Predictors of rebleeding after initial hemostasis with epinephrine injection in high-risk ulcers

AIM: To identify the predictors of rebleeding after initial hemostasis with epinephrine injection (EI) in patients with high-risk ulcers. METHODS: Recent studies have revealed that endoscopic thermocoagulation, or clips alone or combined with EI are superior to EI alone to arrest ulcer bleeding. However, the reality is that EI monotherapy is still common in clinical practice. From October 2006 to April 2008, high-risk ulcer patients in whom hemorrhage was stopped after EI monotherapy were studied using clinical, laboratory and endoscopic variables. The patients were divided into 2 groups: sustained hemostasis and rebleeding. RESULTS: A total of 175 patients (144, sustainedhemostasis; 31, rebleeding) were enrolled. Univariate analysis revealed that older age (≥ 60 years), advanced American Society of Anesthesiology (ASA) status (category Ⅲ , Ⅳ and Ⅴ ), shock, severe anemia (hemoglobin < 80 g/L), EI dose ≥ 12 mL and severe bleeding signs (SBS) including hematemesis or hematochezia were the factors which predicted rebleeding. However, only older age, severe anemia, high EI dose and SBS were independent predictors. Among 31 rebleeding patients, 10 (32.2%) underwent surgical hemostasis, 15 (48.4%) suffered from delayed hemostasis causing major complications and 13 (41.9%) died of these complications. CONCLUSION: Endoscopic EI monotherapy in patients with high-risk ulcers should be avoided. Initial hemostasis with thermocoagulation, clips or additional hemostasis after EI is mandatory for such patients to ensure better hemostatic status and to prevent subsequent rebleeding, surgery, morbidity and mortality.

Link between mutations in ACVRL1 and PLA2G4A genes and chronic intestinal ulcers:A case report and review of literature

BACKGROUND Genetic factors of chronic intestinal ulcers are increasingly garnering attention.We present a case of chronic intestinal ulcers and bleeding associated with mu-tations of the activin A receptor type II-like 1(ACVRL1)and phospholipase A2 group IVA(PLA2G4A)genes and review the available relevant literature.CASE SUMMARY A 20-year-old man was admitted to our center with a 6-year history of recurrent abdominal pain,diarrhea,and dark stools.At the onset 6 years ago,the patient had received treatment at a local hospital for abdominal pain persisting for 7 d,under the diagnosis of diffuse peritonitis,acute gangrenous appendicitis with perforation,adhesive intestinal obstruction,and pelvic abscess.The surgical treat-ment included exploratory laparotomy,appendectomy,intestinal adhesiolysis,and pelvic abscess removal.The patient’s condition improved and he was dis-charged.However,the recurrent episodes of abdominal pain and passage of black stools started again one year after discharge.On the basis of these features and results of subsequent colonoscopy,the clinical diagnosis was established as in-flammatory bowel disease(IBD).Accordingly,aminosalicylic acid,immunotherapy,and related symptomatic treatment were administered,but the symptoms of the patient did not improve significantly.Further investigations revealed mutations in the ACVRL1 and PLA2G4A genes.ACVRL1 and PLA2G4A are involved in angiogenesis and coagulation,respectively.This suggests that the chronic intestinal ulcers and bleeding in this case may be linked to mutations in the ACVRL1 and PLA2G4A genes.Oral Kangfuxin liquid was administered to promote healing of the intestinal mucosa and effectively manage clinical symptoms.CONCLUSION Mutations in the ACVRL1 and PLA2G4A genes may be one of the causes of chronic intestinal ulcers and bleeding in IBD.Orally administered Kangfuxin liquid may have therapeutic potential.

Impact of tibial transverse transport in tissue regeneration and wound healing with perspective on diabetic foot ulcers

In this editorial,we comment on an article by Liao et al published in the current issue of the World Journal of Diabetes.We focus on the clinical significance of tibial transverse transport(TTT)as an effective treatment for patients with diabetic foot ulcers(DFU).TTT has been associated with tissue regeneration,improved blood circulation,reduced amputation rates,and increased expression of early angiogenic factors.Mechanistically,TTT can influence macrophage polarization and growth factor upregulation.Despite this potential,the limitations and conflicting results of existing studies justify the need for further research into its optimal application and development.These clinical implications highlight the efficacy of TTT in recalcitrant DFU and provide lasting stimuli for tissue re-generation,and blood vessel and bone marrow improvement.Immunomodu-lation via systemic responses contributes to its therapeutic potential.Future studies should investigate the underlying molecular mechanisms to enhance our understanding and the efficacy of TTT.This manuscript emphasizes the potential of TTT in limb preservation and diabetic wound healing and suggests avenues for preventive measures against limb amputation in diabetes and peripheral artery disease.Here,we highlight the clinical significance of the TTT and its importance in healing DFU to promote the use of this technique in tissue regeneration.

Efficacy of Huangma Ding or autologous platelet-rich gel for the diabetic lower extremity arterial disease patients with foot ulcers

BACKGROUND Diabetes foot is one of the most serious complications of diabetes and an important cause of death and disability,traditional treatment has poor efficacy and there is an urgent need to develop a practical treatment method.AIM To investigate whether Huangma Ding or autologous platelet-rich gel(APG)treatment would benefit diabetic lower extremity arterial disease(LEAD)patients with foot ulcers.METHODS A total of 155 diabetic LEAD patients with foot ulcers were enrolled and divided into three groups:Group A(62 patients;basal treatment),Group B(38 patients;basal treatment and APG),and Group C(55 patients;basal treatment and Huangma Ding).All patients underwent routine follow-up visits for six months.After follow-up,we calculated the changes in all variables from baseline and determined the differences between groups and the relationships between parameters.RESULTS The infection status of the three groups before treatment was the same.Procalcitonin(PCT)improved after APG and Huangma Ding treatment more than after traditional treatment and was significantly greater in Group C than in Group B.Logistic regression analysis revealed that PCT was positively correlated with total amputation,primary amputation,and minor amputation rates.The ankle-brachial pressure and the transcutaneous oxygen pressure in Groups B and C were greater than those in Group A.The major amputation rate,minor amputation rate,and total amputation times in Groups B and C were lower than those in Group A.CONCLUSION Our research indicated that diabetic foot ulcers(DFUs)lead to major amputation,minor amputation,and total amputation through local infection and poor microcirculation and macrocirculation.Huangma Ding and APG were effective attreating DFUs.The clinical efficacy of Huangma Ding was better than that of autologous platelet gel,which may be related to the better control of local infection by Huangma Ding.This finding suggested that in patients with DFUs combined with coinfection,controlling infection is as important as improving circulation.

Clinical comprehensive treatment protocol for managing diabetic foot ulcers:A retrospective cohort study

BACKGROUND Diabetic foot ulcers(DFUs)are a common complication of diabetes,often leading to severe infections,amputations,and reduced quality of life.The current standard treatment protocols for DFUs have limitations in promoting efficient wound healing and preventing complications.A comprehensive treatment approach targeting multiple aspects of wound care may offer improved outcomes for patients with DFUs.The hypothesis of this study is that a comprehensive treatment protocol for DFUs will result in faster wound healing,reduced amputation rates,and improved overall patient outcomes compared to standard treatment protocols.AIM To compare the efficacy and safety of a comprehensive treatment protocol for DFUs with those of the standard treatment protocol.METHODS This retrospective study included 62 patients with DFUs,enrolled between January 2022 and January 2024,randomly assigned to the experimental(n=32)or control(n=30)group.The experimental group received a comprehensive treatment comprising blood circulation improvement,debridement,vacuum sealing drainage,recombinant human epidermal growth factor and anti-inflammatory dressing,and skin grafting.The control group received standard treatment,which included wound cleaning and dressing,antibiotics administration,and surgical debridement or amputation,if necessary.Time taken to reduce the white blood cell count,number of dressing changes,wound healing rate and time,and amputation rate were assessed.RESULTS The experimental group exhibited significantly better outcomes than those of the control group in terms of the wound healing rate,wound healing time,and amputation rate.Additionally,the comprehensive treatment protocol was safe and well tolerated by the patients.CONCLUSION Comprehensive treatment for DFUs is more effective than standard treatment,promoting granulation tissue growth,shortening hospitalization time,reducing pain and amputation rate,improving wound healing,and enhancing quality of life.

Home-based Detection and Prediction of Diabetic Foot Ulcers at Early Stage Using Sensor Technology and Supervised Learning

For years,foot ulcers linked with diabetes mellitus and neuropathy have significantly impacted diabetic patients’ health-related quality of life(HRQoL). Diabetes foot ulcers impact15% of all diabetic patients at some point in their lives. The facilities and resources used for DFU detection and treatment are only available at hospitals and clinics,which results in the unavailability of feasible and timely detection at an early stage. This necessitates the development of an at-home DFU detection system that enables timely predictions and seamless communication with users,thereby preventing amputations due to neglect and severity. This paper proposes a feasible system consisting of three major modules:an IoT device that works to sense foot nodes to send vibrations onto a foot sole,a machine learning model based on supervised learning which predicts the level of severity of the DFU using four different classification techniques including XGBoost,K-SVM,Random Forest,and Decision tree,and a mobile application that acts as an interface between the sensors and the patient. Based on the severity levels,necessary steps for prevention,treatment,and medications are recommended via the application.

Progress of Research on the Effect of Dietary Care on Patients with Gastritis and Gastric Ulcers

Gastritis gastric ulcer is a common disease of the digestive system,which has a serious impact on the quality of life and health of affected individuals.Dietary care is one of the important measures to treat and prevent gastritis gastric ulcers.This paper reviews the research progress on the impact of dietary care on patients with gastritis and gastric ulcers,including dietary behavioral intervention,dietary habit cultivation,dietary hygiene education,and nutritional support.Studies have shown that rational dietary care was able to improve the clinical symptoms of patients,regulate the intestinal microbial community,anti-inflammatory,antioxidant,and other pathways to improve the pathophysiological state of patients with gastritis and gastric ulcer and prevent recurrence.Therefore,dietary care is of great significance to patients with gastritis and gastric ulcers.

Current scenario of traditional medicines in management of diabetic foot ulcers:A review

Diabetic foot infections and diabetic foot ulcers(DFU)cause significant suffering and are often recurring.DFU have three important pathogenic factors,namely,microangiopathy causing local tissue anoxia,neuropathy making the foot prone to injuries from trivial trauma,and local tissue hyperglycaemia favouring infection and delaying the wound healing.DFU have been the leading cause for non-traumatic amputations of part or whole of the limb.Western medicines focus mainly on euglycaemia,antimicrobials,debridement and wound cover with grafts,and off-loading techniques.Advances in euglycaemic control,foot care and footwear,systemic antimicrobial therapy,and overall health care access and delivery,have resulted in an overall decrease in amputations.However,the process of wound care after adequate debridement remains a major cost burden globally,especially in developing nations.This process revolves around two basic concerns regarding control/eradication of local infection and promotion of faster healing in a chronic DFU without recurrence.Wound modulation with various dressings and techniques are often a costly affair.Some aspects of the topical therapy with modern/Western medicines are frequently not addressed.Cost of and compliance to these therapies are important as both the wounds and their treatment are“chronic.”Naturally occurring agents/medications from traditional medicine systems have been used frequently in different cultures and nations,though without adequate clinical base/relevance.Traditional Chinese medicine involves restoring yin-yang balance,regulating the‘chi’,and promoting local blood circulation.Traditional medicines from India have been emphasizing on‘naturally’available products to control wound infection and promote all the aspects of wound healing.There is one more group of chemicals which are not pharmaceutical agents but can create acidic milieu in the wound to satisfy the above-mentioned basic concerns.Various natural and plant derived products(e.g.,honey,aloe vera,oils,and calendula)and maggots are also used for wound healing purposes.We believe that patients with a chronic wound are so tired physically,emotionally,and financially that they usually accept native traditional medicine which has the same cultural base,belief,and faith.Many of these products have never been tested in accordance to“evidence-based medicine.”There are usually case reports and experience-based reports about these products.Recently,there have been some trials(in vitro and in vivo)to verify the claims of usage of traditional medicines in management of DFU.Such studies show that these natural products enhance the healing process by controlling infection,stimulating granulation tissue,antimicrobial action,promoting fibroblastic activity and collagen deposition,etc.In this review,we attempt to study and analyse the available literature on results of topical traditional medicines,which are usually advocated in the management of DFU.An integrated and‘holistic’approach of both modern and traditional medicine may be more acceptable to the patient,cost effective,and easy to administer and monitor.This may also nevertheless lead to further improvement in quality of life and decrease in the rates of amputations for DFU.

Effect of Bismuth Subgallate/Borneol Combined with Autologous Platelet-Rich Gel in the Treatment of Patients with Diabetic Foot Ulcers

Objective: To explore the effect of Bismuth Subgallate/Borneol (SuileTM BSB) healing dressing combined with autologous platelet-rich gel (APG) in the treatment of diabetic foot ulcer (DFU). Methods: A total of 120 patients with DFU hospitalized in the Changsha Central Hospital from August 2020 to September 2021 were selected and randomly divided into an experimental group (BSB + APG, n = 60) and a control group (BSB, n = 60) according to random number table method. The total therapeutic effect, healing time, hospital stay, level indexes of various inflammatory factors before and after treatment and ulcer area were observed in the two groups. Results: The total effect of the control group was worse than that of the experimental group, and the data between the two groups were significant (P 0.05);after treatment, the levels of inflammatory factors including WBC, CRP, IL-6 and TNF-α in the control group were higher than those in the experimental group, and there was significant difference between the two groups (P 0.05);after 14 days of treatment, the ulcer area in the control group was larger than that in the experimental group, and the data between the two groups were significant (P Conclusion: BSB combined with APG can achieve better therapeutic effect, reduce the inflammatory reaction of patients, and promote wound healing in the treatment of patients with diabetic foot ulcer.

Emerging role of exosomes in ulcerative colitis: Targeting NOD-like receptor family pyrin domain containing 3 inflammasome

Ulcerative colitis(UC)is a chronic recurrent inflammatory bowel disease.Despite ongoing advances in our understanding of UC,its pathogenesis is yet unelu-cidated,underscoring the urgent need for novel treatment strategies for patients with UC.Exosomes are nanoscale membrane particles that mediate intercellular communication by carrying various bioactive molecules,such as proteins,RNAs,DNA,and metabolites.The NOD-like receptor family pyrin domain containing 3(NLRP3)inflammasome is a cytosolic tripartite protein complex whose activation induces the maturation and secretion of proinflammatory cytokines interleukin-1β(IL-1β)and IL-18,triggering the inflammatory response to a pathogenic agent or injury.Growing evidence suggests that exosomes are new modulators of the NLRP3 inflammasome,with vital roles in the pathological process of UC.Here,recent evidence is reviewed on the role of exosomes and NLRP3 inflammasome in UC.First,the dual role of exosomes on NLRP3 inflammasome and the effect of NLRP3 inflammasome on exosome secretion are summarized.Finally,an outlook on the directions of exosome-NLRP3 inflammasome crosstalk research in the context of UC is proposed and areas of further research on this topic are high-lighted.

Advances in the efficacy and safety of nano-silver dressings for diabetic foot ulcers(DFU)healing

As a new antimicrobial material,nano-silver dressing has been widely used in the treatment of diabetic foot ulcer(DFU)wounds in recent years.It not only has achieved a satisfactory effect in promoting the healing of DFU,but also has the advantages in controlling wound infection,relieving pain and reducing the frequency of dressing change.In this review,the principle,efficacy and safety of DFU wound healing were reviewed,and the future research directions were prospected.

Network pharmacology-based approach for exploring the biotargets and mechanisms of vitamin A for the treatment of diabetic foot ulcers

Background:In some developing countries,people have little knowledge about the causes of diabetic foot ulcers.Therefore,public health education for patients on these conditions is a prerequisite for effective pharmacological treatment.Diabetic foot ulcers are a complex symptom of diabetes and are hard to cure due to the lack of efficacious medicine and alternative treatment approaches.Vitamin A(VA)is known to have potent biological functions,including skin repair and immunoregulation.However,the potential pharmacological effects and molecular mechanisms of VA on foot ulcers are still to be discovered.Methods:By using bioinformatic/computational analyses,including network pharmacology,gene ontology and the Kyoto Encyclopedia of Genes and Genomes enrichment analysis,we aimed to identify and reveal the pharmacological targets,molecular mechanisms,biological functions,and signaling pathways of VA in the treatment of diabetic foot ulcers.Results:A total of 66 intersection genes were identified as candidate targets of VA,which are related to diabetic foot ulcers.Therein,18 core genes/targets,namely JUN,MAPK1,THRB,MAPK14,MTNR1B,CXCR3,ESR1,AR,HDAC1,IL-10,CNR1,DRD2,EGFR,ADRA2A,CCND1,RXRB,RARA,and RXRA,were further identified.Furthermore,the biological processes,cell components,and molecular functions which may underlie the effects of VA against diabetic foot ulcers were characterized.Conclusion:Based on our findings,we concluded that the pharmacological effects of VA on diabetic foot ulcers primarily involve the promotion of cellular regeneration and proliferation and the inhibition of inflammatory response.The core genes/targets may potentially serve as promising biomarkers for the diagnosis of diabetic foot ulcers.

Efficacy of tibial transverse transport combined with platelet-rich plasma versus platelet-rich plasma alone in the treatment of diabetic foot ulcers:A meta-analysis

Background:Diabetic foot ulcers(DBFU)are one of the main complications of diabetes.Platelet-rich plasma(PRP)treatment is a commonly used treatment option.Tibial transverse transport(TTT)also has a therapeutic effect on DBFU.Some studies have found that the TTT combined with PRP(TTT&PRP)has a significant effect on DBFU.Methods:PubMed,Cochrane Library,Web of Science,EMBASE,Chinese Biomedical Literature,CNKI,VIP,and Wanfang databases were used to find literature on the treatment of DBFUs using the TTT and PRP treatment according to the inclusion criteria.The specific inclusion criteria are as follows:(1)research type:clinical controlled trials,including retrospective cohort and randomized controlled studies;(2)diagnosis of DBFUs that does not include a definitively diagnosed traumatic ulcer;(3)original materials of Chinese and English literature published in full text.The exclusion criteria are:(1)the research group was not defined or grouped;(2)nonrandomized controlled trials,non-cohort studies,non-case-control studies,retrospective studies,and case reports;(3)repetitive research and animal experimentation;(4)ulcers caused by other diseases;(5)conservative treatment or no use of invasive treatment methods.Review Manager software(version 5.3)was used to conduct a meta-analysis of the included results.Result:The literature included 6 randomized controlled studies,including 508 patients,254 patients in the PRP treatment group,and 254 patients in the TTT&PRP group.The meta-analysis results showed that in terms of treatment efficacy,the TTT&PRP combined treatment group had a higher efficacy than the PRP group.After treatment,the TTT&PRP group had better treatment effects in psychological function,physiological function,and social function compared to the PRP group.After treatment,the TTT&PRP group showed a significant increase in serum epidermal growth factor(EGF),vascular endothelial growth factor(VEGF),basic fibroblast growth factor(bFGF),and platelet-derived growth factor(PDGF)levels compared to the PRP group.In terms of wound healing after treatment,the TTT&PRP group performed better than the PRP group in terms of postoperative wound reduction rate,bacterial clearance rate,granulation tissue coverage rate,and granulation tissue growth thickness.Conclusion:TTT combined with PRP was more effective than PRP alone in treating DBFUs.

XB130 inhibits healing of diabetic skin ulcers through the PI3K/Akt signalling pathway

BACKGROUND Diabetic skin ulcers,a significant global healthcare burden,are mainly caused by the inhibition of cell proliferation and impaired angiogenesis.XB130 is an adaptor protein that regulates cell proliferation and migration.However,the role of XB130 in the development of diabetic skin ulcers remains unclear.AIM To investigate whether XB130 can regulate the inhibition of proliferation and vascular damage induced by high glucose.Additionally,we aim to determine whether XB130 is involved in the healing process of diabetic skin ulcers,along with its molecular mechanisms.METHODS We conducted RNA-sequencing analysis to identify the key genes involved in diabetic skin ulcers.We investigated the effects of XB130 on wound healing using histological analyses.In addition,we used reverse transcription-quantitative polymerase chain reaction,Western blot,terminal deoxynucleotidyl transferasemediated dUTP nick end labeling staining,immunofluorescence,wound healing,and tubule formation experiments to investigate their effects on cellular processes in human umbilical vein endothelial cells(HUVECs)stimulated with high glucose.Finally,we performed functional analysis to elucidate the molecular mechanisms underlying diabetic skin ulcers.RESULTS RNA-sequencing analysis showed that the expression of XB130 was up-regulated in the tissues of diabetic skin ulcers.Knockdown of XB130 promoted the healing of skin wounds in mice,leading to an accelerated wound healing process and shortened wound healing time.At the cellular level,knockdown of XB130 alleviated high glucose-induced inhibition of cell proliferation and angiogenic impairment in HUVECs.Inhibition of the PI3K/Akt pathway removed the proliferative effects and endothelial protection mediated by XB130.CONCLUSION The findings of this study indicated that the expression of XB130 is up-regulated in high glucose-stimulated diabetic skin ulcers and HUVECs.Knockdown of XB130 promotes cell proliferation and angiogenesis via the PI3K/Akt signalling pathway,which accelerates the healing of diabetic skin ulcers.

Gastroprotective Effect of Alpinia zerumbet(Pers.)Burttet Smith on Ethanol-induced Gastric Ulcers in vivo and vitro

[Objectives]To explore the protective effect of Alpinia zerumbet(Pers.)Burttet Smith ethanol extraction(YSJ)on gastric ulcers.[Methods]The ethanol-induced gastric ulcer model was generated by male Kunming mice.The mice were divided into six groups,including control,model(GU),positive omeprazole enteric-coated capsules(18 mg/kg),YSJ low(1.17 g/kg),medium(2.34 g/kg)and high(4.68 g/kg)dose groups.To observe the state of gastric tissues,hematoxylin and eosin(H&E)staining was applied and immunohistochemistry(IHC)was used to evaluate the expression of nuclear factor kappa-B p65(NF-κB p65),interleukin 6(IL-6),tumor necrosis factor-α(TNF-α),and Cyclooxygenase-2(COX-2)in gastric tissues.The ulcer index,biochemical parameters,and inflammatory proteins were evaluated.In vitro,GES-1 cells were induced by anhydrous ethanol to found gastric ulcer model.The groups were the same as in vivo experiment.Cytotoxicity was tested by MTT and IL-1β,TNF-α,and IL-6 were detected by Elisa assays.[Results]The injuries of gastric tissue in the model group were unambiguously observed and improved after YSJ treatment.The levels of interleukin 1 beta(IL-1β),interleukin 6(IL-6),interleukin 8(IL-8),and TNF-αin serum and tissues were decreased(P<0.05 or 0.01),whereas interleukin 4(IL-4)and prostaglandin E 2(PGE 2)were increased after treatment with YSJ(P<0.05 or 0.01).The levels of IL-1β,IL-6,TNF-α,and IL-8 were decreased in YSJ groups,while IL-4 and PGE 2 presented the opposite trend.The protein expression of p-NF-κB,NF-κB,p-IκBα,IκBα,and TNF-αwas inhibited after treatment with YSJ(P<0.05 or 0.01).[Conclusions]These results demonstrate that YSJ alleviates the occurrence and development of gastric ulcers via inhibiting inflammation.

Sequential treatment for diabetic foot ulcers in dialysis patients:A case report

BACKGROUND Diabetic foot ulcers(DFUs)are common in patients with diabetes,especially those undergoing hemodialysis.In severe cases,these ulcers can cause damage to the lower extremities and lead to amputation.Traditional treatments such as flap transposition and transfemoral amputation are not always applicable in all cases.Therefore,there is a need for alternative treatment methods.CASE SUMMARY This report describes a 62-year-old female patient who was admitted to the hospital with plantar and heel ulcers on her left foot.The patient had a history of renal failure and was undergoing regular hemodialysis.Digital subtraction angiography showed extensive stenosis and occlusion in the left superficial femoral artery,left peroneal artery and left posterior tibial artery.Following evaluation by a multidisciplinary team,the patient was diagnosed with type 2 DFUs(TEXAS 4D).Traditional treatments were deemed unsuitable,and the patient was treated with endovascular surgery in the affected area,in addition to supportive medical treatment,local debridement,and sequential repair using split-thickness skin and tissue-engineered skin grafts combined with negative pressure treatment.After four months,the wound had completely healed,and the patient was able to walk with a walking aid.CONCLUSION This study demonstrates a new treatment method for DFUs was successful,using angioplasty,skin grafts,and negative pressure.

Immune function, gastrointestinal hormone levels, and their clinical significance in patients with gastric ulcers complicated with depression

BACKGROUND Gastric ulcer(GU)is a common digestive tract disease,and medical records of GU combined with depression are increasingly common.Currently,the risk factors and pathogenesis of GU complicated with depression remain unclear.Low immune function and gastrointestinal hormone levels may also be significant risk factors.Therefore,this study explored the immune function and gastrointestinal hormone levels in patients with GU combined with depression.AIM To explore the immune function,gastrointestinal hormone level,and clinical significance of patients with GU combined with depression.METHODS A retrospective analysis was conducted on 300 patients with GU combined with depression admitted to Guizhou Provincial People’s Hospital from January 2021 to June 2022 as the study subjects.According to the Hamilton Depression Scale(HAMD)score,patients were divided into mild-to-moderate(n=210)and heavy(n=90)groups.Basic data,immune function indices[immunoglobulin A(IgA),IgM,IgG,serum CD4+and CD8+percentage,and CD4+/CD8+ratio],and gastrointestinal hormone indices[serum gastrin(GAS),cholecystokinin(CCK),and motilin(MTL)levels]were collected.The basic data of the two groups were compared,and the immune function and gastrointestinal hormone indices were analyzed.Multivariate logistic regression was used to analyze the factors influencing the severity of GU complicated with depression.The receiver operating characteristic(ROC)curve and area under the ROC curve(AUC)were used to analyze the value of the immune function index,gastrointestinal hormone index,and combined index in predicting the severity of GU complicated with depression.RESULTS There were no marked differences in sex,age,body mass index,abdominal distension,abdominal pain,belching,nausea,vomiting,or sleep disorders between the heavy and mild-to-moderate groups(P>0.05).There was a marked difference in the family history of depression between the heavy and mild-to-moderate groups(P<0.05).There were significant differences in serum IgA and IgM levels and serum CD4+,CD8+,and CD4+/CD8+ratios between the heavy and mild-to-moderate groups(P<0.05).Multivariate analysis showed that IgA,IgM,GAS,and CCK serum levels influenced the severity of GU with depression(P<0.05).The AUC of the ROC curve for serum IgA level predicting GU with depression severity was 0.808[95%confidence interval(CI):0.760-0.857],the AUC of the serum IgM level was 0.757(95%CI:0.700-0.814),the AUC of the serum GAS level was 0.853(95%CI:0.810-0.897),the AUC of the serum CCK level was 0.762(95%CI:0.709-0.822),the AUC of immune function(IgA,IgM)and gastrointestinal hormone levels(GAS,CCK)for the prediction of GU with depression severity was 0.958(95%CI:0.933-0.976).CONCLUSION Important factors influencing GU complicated with depression are serum IgA,IgM,GAS,and CCK indicators.They can be used as indicators to predict the severity of GU complicated with depression.

Vitamin D deficiency among outpatients and hospitalized patients with diabetic foot ulcers:A systematic review and meta-analysis

BACKGROUND The definition of diabetic foot syndrome(DFS)varies depending on the location and resources.Few classifications are available according to the indication.DF ulcers and vitamin D deficiency are common diseases among patients with diabetes.Previous literature has shown an association between DF ulcer(DFU)and vitamin D deficiency.However,the available meta-0analysis was limited by substantial bias.AIM To investigate the association between DFUs and vitamin D levels.METHODS We searched PubMed,MEDLINE,and Cochrane Library,EBSCO,and Google Scholar for studies comparing vitamin D levels and DF.The keywords DFU,DFS,diabetic septic foot,vitamin D level,25-hydroxy vitamin D,vitamin D status,and vitamin D deficiency were used.The search engine was set for articles published during the period from inception to October 2022.A predetermined table was used to collect the study information.RESULTS Vitamin D level was lower among patients with DFU compared to their counterparts[odds ratio(OR):-5.77;95%confidence interval(CI):-7.87 to-3.66;χ2 was 84.62,mean difference,9;I2 for heterogeneity,89%;P<0.001 and P for overall effect<0.001].The results remained robust for hospitalized patients(OR:-6.3295%CI:-11.66 to-0.97;χ2 was 19.39;mean difference,2;I2 for heterogeneity,90%;P=0.02).CONCLUSION Vitamin D was lower among outpatients and hospitalized patients with DFUs.Further larger randomized controlled trials are needed.

Intravitreal conbercept injection with panretinal photocoagulation for high-risk proliferative diabetic retinopathy with vitreous hemorrhage

AIM:To assess the clinical efficacy and safety of combining panretinal photocoagulation(PRP)with intravitreal conbercept(IVC)injections for patients with high-risk proliferative diabetic retinopathy(HR-PDR)complicated by mild or moderate vitreous hemorrhage(VH),with or without diabetic macular edema(DME).METHODS:Patients diagnosed with VH with/without DME secondary to HR-PDR and received PRP combined with IVC injections were recruited in this retrospective study.Upon establishing the patient’s diagnosis,an initial IVC was performed,followed by prompt administration of PRP.In cases who significant bleeding persisted and impeded the laser operation,IVC was sustained before supplementing with PRP.Following the completion of PRP,patients were meticulously monitored for a minimum of six months.Laser therapy and IVC injections were judiciously adjusted based on fundus fluorescein angiography(FFA)results.Therapeutic effect and the incidence of adverse events were observed.RESULTS:Out of 42 patients(74 eyes),29 were male and 13 were female,with a mean age of 59.17±12.74y(33-84y).The diabetic history was between 1wk and 26y,and the interval between the onset of visual symptoms and diagnosis of HR-PDR was 1wk-1y.The affected eye received 2.59±1.87(1-10)IVC injections and underwent 5.5±1.02(4-8)sessions of PRP.Of these,68 eyes received PRP following 1 IVC injection,5 eyes after 2 IVC injections,and 1 eye after 3 IVC injections.Complete absorption of VH was observed in all 74 eyes 5-50wk after initial treatment,with resolution of DME in 51 eyes 3-48wk after initial treatment.A newly developed epiretinal membrane was noted in one eye.Visual acuity significantly improved in 25 eyes.No complications such as glaucoma,retinal detachment,or endophthalmitis were reported.CONCLUSION:The study suggests that the combination of PRP with IVC injections is an effective and safe modality for treating diabetic VH in patients with HR-PDR.

Are we ready to use new endoscopic scores for ulcerative colitis?

For ulcerative colitis(UC),the variability in inflammatory activity along the colon poses a challenge in management.The focus on achieving endoscopic healing in UC is evident,where the UC Endoscopic Index of Severity and Mayo Endoscopic Subscore are commonly used for evaluation.However,these indices primarily consider the most severely affected region.Liu et al recent study validates the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting(TIGER)score offering a comprehensive assessment of inflammatory activity across diverse segments of the colon and rectum and a reliable index correlating strongly with UC Endoscopic Index of Severity and moderately with Mayo Endoscopic Subscore(MES).Despite recommendation,certain aspects warrant further invest-igation.Fecal calprotectin,an intermediate target,correlates with TIGER and should be explored.Determining TIGER scores defining endoscopic remission and response,evaluating agreement with histological activity,and assessing inter-endoscopist agreement for TIGER require scrutiny.Exploring the correlation between TIGER and intestinal ultrasound,akin to MES,adds value.
