Three-dimensional choroidal vascularity index and choroidal thickness in fellow eyes of acute and chronic primary angle-closure using swept-source optical coherence tomography

AIM:To compare the three-dimensional choroidal vascularity index(CVI)and choroidal thickness between fellow eyes of acute primary angle-closure(F-APAC)and chronic primary angle-closure glaucoma(F-CPACG)and the eyes of normal controls.METHODS:This study included 37 patients with unilateral APAC,37 with asymmetric CPACG without prior treatment,and 36 healthy participants.Using swept-source optical coherence tomography(SS-OCT),the macular and peripapillary choroidal thickness and three-dimensional CVI were measured and compared globally and sectorally.Pearson’s correlation analysis and multivariate regression models were used to evaluate choroidal thickness or CVI with related factors.RESULTS:The mean subfoveal CVIs were 0.35±0.10,0.33±0.09,and 0.29±0.04,and the mean subfoveal choroidal thickness were 315.62±52.92,306.22±59.29,and 262.69±45.55μm in the F-APAC,F-CPACG,and normal groups,respectively.All macular sectors showed significantly higher CVIs and choroidal thickness in the F-APAC and F-CPACG eyes than in the normal eyes(P<0.05),while there were no significant differences between the F-APAC and F-CPACG eyes.In the peripapillary region,the mean overall CVIs were 0.21±0.08,0.20±0.08,and 0.19±0.05,and the mean overall choroidal thickness were 180.45±54.18,174.82±50.67,and 176.18±37.94μm in the F-APAC,F-CPACG,and normal groups,respectively.There were no significant differences between any of the two groups in all peripapillary sectors.Younger age,shorter axial length,and the F-APAC or F-CPACG diagnosis were significantly associated with higher subfoveal CVI and thicker subfoveal choroidal thickness(P<0.05).CONCLUSION:The fellow eyes of unilateral APAC or asymmetric CPACG have higher macular CVI and choroidal thickness than those of the normal controls.Neither CVI nor choroidal thickness can distinguish between eyes predisposed to APAC or CPACG.A thicker choroid with a higher vascular volume may play a role in the pathogenesis of primary angle-closure glaucoma.

Clinicopathological features of 11 cases of chronic hepatitis B infection complicated with primary biliary cholangitis

BACKGROUND Only a few cases of chronic hepatitis B(CHB)with primary biliary cholangitis(PBC)have been reported based on histological evidence from liver biopsies.AIM To observe the clinicopathological features and outcomes of 11 patients with CHB infection complicated by PBC.METHODS Eleven patients with CHB and PBC who underwent liver biopsy at the Zhenjiang Third Hospital,affiliated with Jiangsu University,and Wuxi Fifth People’s Hospital,from January 2005 to September 2020,were selected.All patients initially visited our hospital with CHB and were pathologically diagnosed with CHB and PBC.RESULTS Only five had elevated alkaline phosphatase levels,nine were positive for antimitochondrial antibody(AMA)-M2,and two were negative for AMA-M2.Two had jaundice and pruritus symptoms,10 had mildly abnormal liver function,and one had severely elevated bilirubin and liver enzyme levels.The pathological characteristics of CHB complicated by PBC overlapped with those of PBCautoimmune hepatitis(AIH).When necroinflammation of the portal area is not obvious,the pathological features of PBC are predominant,similar to the features of PBC alone.When the interface is severe,biliangitis will occur,with a large number of ductular reactions in zone 3.Unlike the PBC-AIH overlap pathology,this pathology is characterized by a small amount of plasma cell infiltration.Unlike PBC,lobulitis is often observed.CONCLUSION This is the first large case series to show that the rare pathological features of CHB with PBC are similar to those of PBC-AIH and small duct injury was observed.

Analysis of the Status and Factors Influencing Anxiety and Depression in Patients with Chronic Heart Failure and Their Primary Caregivers: Empirical Quantitative Research

Objective: This study examined the associations between anxiety, depression, and quality of life among hospitalized patients with chronic heart failure and their primary caregivers. Patients and Methods: Between May and September 2018, the data were collected from 61 patients and their caregivers. Demographic information of CHF patients was collected by questionnaires; the Hospital Anxiety and Depression Scale (HADS) and the Minnesota Living with Heart Failure Questionnaire (MLHFQ) were used to assess CHF patient’s anxiety, depression and quality of life (QOL); the HADS, the Family Caregiver Quality of Life (FAMQOL) were used to assess primary caregivers’ anxiety, depression and QOL. Descriptive statistics, correlation analysis, independent-sample t-test, one-way analysis of variance and multiple stepwise regression were used in the statistical analysis. SPSS 17.0 was used to manage and perform statistical analyses. Results: Quality of life, anxiety, and depression of the patients and caregivers had significant positive correlations. Gender, quality of life, number of hospitalizations, duration of patients’ heart failure, and the quality of life of caregivers influenced patients’ anxiety. Gender, quality of life, relationship with the patient, and depression of caregivers influenced their anxiety. The quality of life and anxiety of patients influenced their depression. Daily caregiving time, anxiety, relationship with patients, and the patients’ heart function influenced caregivers’ depression. Conclusion: The patients and caregivers experienced anxiety and depression, which interacts and decreases their quality of life. It is important to regularly assess anxiety, depression, and quality of life in patients with chronic heart failure and their primary caregivers.

Satellite glial cells in sensory ganglia play a wider role in chronic pain via multiple mechanisms

Satellite glial cells are unique glial cells that surround the cell body of primary sensory neurons.An increasing body of evidence suggests that in the presence of inflammation and nerve damage,a significant number of satellite glial cells become activated,thus triggering a series of functional changes.This suggests that satellite glial cells are closely related to the occurrence of chronic pain.In this review,we first summarize the morphological structure,molecular markers,and physiological functions of satellite glial cells.Then,we clarify the multiple key roles of satellite glial cells in chronic pain,including gap junction hemichannel Cx43,membrane channel Pannexin1,K channel subunit 4.1,ATP,purinergic P2 receptors,and a series of additional factors and their receptors,including tumor necrosis factor,glutamate,endothelin,and bradykinin.Finally,we propose that future research should focus on the specific sorting of satellite glial cells,and identify genomic differences between physiological and pathological conditions.This review provides an important perspective for clarifying mechanisms underlying the peripheral regulation of chronic pain and will facilitate the formulation of new treatment plans for chronic pain.

Occult Adrenal Insufficiency in Patients with Chronic Renal Disease

Background: Addison’s disease is a rare disorder of the adrenal cortex that leads to inadequate production of cortisol initially followed by aldosterone and androgens. Its manifestations are usually slow and non-specific with potential for life-threatening adrenal crisis following hypermetabolic demands (infection, trauma, surgery). Patients: Over the past 10 years, 19 CRD-patients were diagnosed with occult PAI in our center. Results: Unprovoked hypotension was the most common manifestations of occult PAI and was the unmasking event in 11 (58%). It was without significant cardiac and/or severe systemic sepsis and was refractory to isotonic saline infusions. Equal number of the remaining patients (n = 2) presented with persistent and inexplicable electrolytes abnormalities viz. 1) hyponatremia despite restricted oral fluid intake, lack of dehydration and massive fluid overload, as well as 2) hyperkalemia despite potassium-restricted diet, hyperkalemic drugs and adequate therapy with Furosemide and low-potassium dialysis-baths. On the other hand, similar proportions presented with unprovoked 3) progressive weight loss, decrease appetite and cachexia as well as 4) frequent hypoglycemic attacks. All patients were treated and were medically stable after 29 (2 - 60) months of follow up. Autoantibodies to 21-hydroxylase enzyme were positive in 16 (90%). At diagnosis, and subsequent follow up, only 7 patients (37%) had multi-endocrine dysfunction of whom 2 with type 1 and 5 with type 2. Conclusion: High index of suspicion should be exerted in diagnosis of PAI in patients with CRD, since its clinical picture is similar to CRD manifestations and complications. In those patients, confirmatory tests and specific management can save their lives. .

Research Progress on the Immunomodulatory Effect of Mesenchymal Stem Cells on Chronic Periodontitis

Periodontal disease is an inflammatory and destructive disease of periodontal support tissue caused by microorganisms in dental plaque. During the development of periodontal disease, host immune regulation plays an important role, and unnecessary excessive immune regulation often exacerbates the course of chronic periodontal disease. Mesenchymal stem cells (MSCs) are adult stem cells with self replication ability and multi-directional differentiation potential. Many studies have found that MSCs have strong immunosuppressive effects on both adaptive and innate immunity. In recent years, literature has reported that MSCs are involved in the immune regulatory effect of chronic periodontal disease, inhibiting its inflammatory response and alveolar bone resorption, but the specific regulatory mechanism has not been elucidated. This article reviews the current research status of the immune regulatory effects of MSCs on chronic periodontitis.

Efficacy of Low-Dose Rituximab in Primary Immune Thrombocytopenia

Objective:To explore the effect of low-dose rituximab in primary immune thrombocytopenia.Methods:From January 2022 to January 2023,60 patients with primary immune thrombocytopenia were randomly divided into two groups.The control group was treated with standard doses of rituximab,and the observation group was treated with low doses of rituximab.Rituximab was used for treatment,and the clinical curative effect of the two groups was observed.Results:Before treatment,there was no statistically significant difference in platelet count(PLT),anti-GPⅡb/Ⅲa antibody,and anti-GPⅠb/Ⅸantibody between the two groups(P>0.05).After treatment,the PLT of the two groups increased significantly.Antibodies were all decreased,and there was no significant difference between the two groups(P>0.05).The incidence of adverse reactions in the observation group was 13.33%,and that in the control group was 40.00%.The adverse reactions in the observation group were significantly lower than the control group(P<0.05).Conclusion:In the clinical treatment of primary immune thrombocytopenia,low-dose rituximab can control the progression of the disease,improve blood routine indicators,and have fewer adverse reactions.

Diffusion tensor imaging of optic nerve and optic radiation in primary chronic angle-closure glaucoma using 3T magnetic resonance imaging

AIM: To evaluate the value of quantitative diffusion tensor imaging (DTI) in assessing the axonal and myelin damage of the optic nerves and optic radiations in patients with chronic primary angle -closure glaucoma (PACG) by using high -field magnetic resonance (MR) imaging (3T). METHODS: Twenty patients with bilateral chronic PACG and twenty age - and sex matched disease -free control subjects were enrolled. Conventional MRI and DTI were performed on all subjects using 3T MR scanner. Mean diffusivity (MD), fractional anisotropy (FA), axial diffusivities (AD) and radial diffusivities (RD) of each optic nerve and each optic radiation were measured by using post -processing software of DTI studio 2.3, and then compared between left eyes and right eyes and between patients group and control group. The pairedsample t- test were used. RESULTS: There was no abnormality in the shape and signal intensity of the optic nerves and optic radiations in patients group and control group on the conventional MRI. No significant differences were observed in the FA, MD, AD and RD between the right and left optic nerves and optic radiations within patients group and control group (P>0.05). The optic nerves and optic radiations of patients with chronic PACG, as compared with control subjects, had significantly higher MD, AD, RD and significantly lower FA (P<0.05). CONCLUSION: The diffusivity of optic nerves and optic radiations in chronic PACG group showed abnormal and diffusivity parameters could be used markers of axonal and myelin injury in glaucoma.

Effect of liniment levamisole on cellular immune functions of patients with chronic hepatitis B

AIM: To explore the effects of liniment levamisole on cellular immune functions of patients with chronic hepatitis B. METHODS: The levels of T lymphocyte subsets and mlL-2R in peripheral blood mononuclear cells (PBMCs) were measured by biotin-streptavidin (BSA) technique in patients with chronic hepatitis B before and after the treatment with liniment levamisole. RESULTS: After one course of treatment with liniment levamisole, the levels of CD3+, CD4+, and the ratio of CD4+/CD8+ increased as compared to those before the treatment but the level of CD8+ decreased. The total expression level of mIL-2R in PBMCs increased before and after the treatment with liniment levamisole. CONCLUSION: Liniment levamisole may reinforce cellular immune functions of patients with chronic hepatitis B.

Effects of Maxingloushi decoction on immune inflammation and programmed death markers in mice with chronic obstructive pulmonary disease

BACKGROUND: To investigate effects of Maxingloushi decoction on lung inflammation and programmed death markers(programmed death-1 [PD-1], programmed death-ligand 1 [PD-L1]) in the lung tissue, peripheral blood, and bronchoalveolar lavage fl uid(BLF) in a mouse model of chronic obstructive pulmonary disease(COPD).METHODS: Thirty-six mature male BALB/C mice were randomly divided into normal group(group A, n=6), COPD model group(group B, n=10), Maxingloushi decoction + COPD group(group C, n=10), and PD-1 inhibitor + COPD group(group D, n=10). The COPD model was established by smoke inhalation combined with lipopolysaccharide(LPS). Levels of PD-1 and PD-L1 in plasma and BLF were measured by enzyme-linked immunosorbent assay(ELISA). Histopathological techniques were used to semi-quantitatively analyze the immuno-fluorescence optical density(IOD) value of the lung tissue. RESULTS: In plasma and BLF, the expression of PD-1 in the group B was higher than that in the group A, and the expression of PD-L1 was lower than that in the group A. The expression of PD-1 and PD-L1 in the lung tissue was normalized in the group C in comparison with the group B(P<0.05) and the group D(P<0.05), and infl ammatory cell infiltration in the lung tissue was also improved.CONCLUSIONS: These findings reveal that COPD causes an immune imbalance in the peripheral blood and lung tissue, and that both Maxingloushi decoction and PD-1 inhibitor treatment can mitigate lung inflammation in COPD by reducing PD-1 expression and increasing PD-L1 expression. The treatment effect of Maxingloushi decoction may be superior to that of PD-1 inhibitor.

Alterations in intestinal microbiota composition coincide with impaired intestinal morphology and dysfunctional ileal immune response in growing-finishing pigs under constant chronic heat stress

Background:Previous studies had shown that short-term acute heat stress(HS)affected the host’s metabolism and intestinal microbiota independent of feed intake(FI)reduction,and long-term calorie restriction caused intestinal morphological injuries and gut microbial alterations.However,research on the effects of constant chronic HS on intestinal microbial composition and the roles of FI reduction played in is limited.This study aimed to investigate the effects of 7-day constant chronic HS on the composition of intestinal microbes in growing-finishing pigs,and its relationship with pigs’performance,intestinal morphology,and ileal immune response.Twenty-four growingfinishing pigs(Duroc×Large White×Landrace,30±1 kg body weight)were randomly assigned to three treatments(n=8),1)thermal neutral(TN)conditions(25±1℃)with ad libitum FI,2)HS conditions(35±1℃)with ad libitum FI,3)pair-fed(PF)with HS under TN conditions to discriminate the confounding effects of dissimilar FI,and the FI was the previous day’s average FI of HS.The small intestinal segments(duodenum,jejunum,and ileum)and feces were collected on d 8.Results:Results indicated that HS drastically declined(P<0.05)average daily gain(ADG)and average daily feed intake(ADFI)(about 61%)in comparison with TN,and caused hyperpyrexia,meanwhile PF caused hypothermia.Morphological observation by light and electron microscopes showed that both HS and PF treatment decreased(P<0.05)the villus and microvillus height compared with TN.Additionally,HS increased(P<0.05)protein expression of heat shock protein 70 in the duodenum,jejunum,and ileum.Furthermore,the expression of tight junction protein zonula occluden-1(ZO-1)in the duodenum and ileum,and Occludin in the ileum were enhanced(P<0.05)compared with TN and PF.Moreover,HS significantly enhanced(P<0.05)the mRNA relative expression of inflammatory cytokines(TLR-2,TLR-4,and tumor necrosis factor-α(TNF-α),IL-6,IL-8,PG1–5,β-defensin 2(pBD-2)),mucins(mucin-1 and mucin-2)and P65 protein level in the ileal mucosa tissue.Intestinal microbiota analysis by 16S rRNA sequencing showed lower(P<0.10)αdiversity in both HS and PF,and a separated cluster ofβdiversity among groups.Compared with TN,HS but not PF mainly reduced(FDR<0.05)Bacteroidetes(phylum),Bacteroidia(class)and elevated the proportions of Proteobacteria(phylum,FDR<0.05),Bacillales(order,FDR<0.05),Planococcaceae(family,FDR<0.05),Kurthia(genus,FDR<0.05),Streptococcaceae(family,FDR<0.10)and Streptococcus(genus,FDR<0.10).Notably,Lactobacillales(order)was decreased(FDR<0.05)by PF alone.Furthermore,the Spearman correlation analysis indicated that the microbes prevalent in HS were positively(P<0.05)associated with intestinal morphological injuries indicators and ileal immune response parameters,and the microbes reduced in HS were negatively(P<0.05)with the performance data.Conclusions:Intestinal morphological injuries and ileal immune response caused by constant chronic HS independent of FI showed close connections with alterations in intestinal microbiota in growing-finishing pigs.

Heterogeneity of immune control in chronic hepatitis B virus infection:Clinical implications on immunity with interferon-αtreatment and retreatment

Hepatitis B virus(HBV)infection is a global public health issue.Interferon-α(IFN-α)treatment has been used to treat hepatitis B for over 20 years,but fewer than 5%of Asians receiving IFN-αtreatment achieve functional cure.Thus,IFN-αretreatment has been introduced to enhance antiviral function.In recent years,immune-related studies have found that the complex interactions between immune cells and cytokines could modulate immune response networks,including both innate and adaptive immunity,triggering immune responses that control HBV replication.However,heterogeneity of the immune system to control HBV infection,particularly HBV-specific CD8^(+)T cell heterogeneity,has consequential effects on T cell-based immunotherapy for treating HBV infection.Altogether,the host’s genetic variants,negative-feedback regulators and HBV components affecting the immune system's ability to control HBV.In this study,we reviewed the literature on potential immune mechanisms affecting the immune control of HBV and the clinical effects of IFN-αtreatment and retreatment.

Primary balloon angioplasty for chronic occlusion of intracranial internal carotid artery: A case report

Chronic occlusion of large intracranial arteries is the main cause of ischemic stroke in China.Patients with symptomatic intracranial artery occlusion and hemodynamic impairment are at high risk of recurrent stroke.Chronic occlusion of the intracranial segment of the internal carotid artery is a common type of intracranial artery occlusion.Medical management is regarded as the standard treatment for this disease.With the development of endovascular treatment,some patients with chronic cerebral artery occlusion have achieved satisfactory results with endovascular therapy.We reported a patient with symptomatic chronic occlusion of the ophthalmic segment of the internal carotid artery.Simple balloon angioplasty was performed,and the occluded ophthalmic segment of the internal carotid artery was successfully recanalized without perioperative complications.At 4 months followup,the internal carotid artery remained patent and perfusion of the right cerebral hemisphere improved dramatically.In addition,we briefly reviewed the relevant literature.

Primary Chronic Angle-closure Glaucoma in Chinese——A Clinical Exploration of Its Pathogenesis And Natural Course

Using an potic microgauge attached to the slit-lamp, the entrance of anterior chamber angle was...

The Primary Motor Cortex Stimulation Attenuates Cold Allodynia in a Chronic Peripheral Neuropathic Pain Condition in <i>Rattus norvegicus</i>

Background: The primary motor cortex (M1) stimulation (MCS) is a useful tool for attenuation of the peripheral neuropathic pain in patients with pharmacologically refractory pain. Furthermore, that neurological procedure may also cause antinociception in rodents with neuropathic pain. Cold allodynia is a frequent clinical finding in patients with neuropathic pain, then, we evaluated if an adapted model of neuropathy induced by chronic constriction injury (CCI) of the ischiadicus nervus (sciatic nerve) produces cold allodynia in an animal model of chronic pain. In addition, we also investigated the effect of the electrical stimulation of the M1 on chronic neuropathic pain condition in laboratory animals. Methods: Male Wistar rats were used. An adapted model of peripheral mononeuropathy induced by CCI was carried out by placing a single loose ligature around the right sciatic nerve. The acetone test was used to evaluate the cold allodynia in CCI or Sham (without ligature) rats. The MCS (M1) was performed at low-frequency (20 μA, 100 Hz) during 15 s by deep brain stimulation (DBS-Thomas Recording device) 21 days after CCI or Sham procedures. The cold allodynia was measured before and immediately after the neurostimulation of M1 in the following time-window: 0, 15 and 30 min after MCS. Results: Cold allodynia threshold increased in animals with chronic neuropathic pain submitted to the acetone test 21 days after the CCI surgery. The M1-stimulation by DBS procedure decreased the cold allodynia immediately and until 30 min after M1-stimulation in rats with chronic neuropathic pain. Conclusion: The current proposal for a CCI model by a single loose ligature of the sciatic nerve can be employed as an experimental model of chronic neuropathic pain in rats submitted to peripheral nervous system injury. The M1-stimulation produced antinociception in rats with chronic neuropathic pain. Thus, we reinforced that the MCS decreases cold allodynia in laboratory animals submitted to persistent sciatic nerve constriction and can be a more reasonable procedure for the treatment of chronic intractable neuropathic pain.

Polypharmacy in Primary Care Practices among Chronic Elderly Patients in Gaza Strip

Introduction: The increasing number of elderly, and drug use among the elderly, emphasizes the need for continuous monitoring of drug utilization. Chronic diseases are frequent among the older population;the rate of drug related problems and drug-drug interactions (DDIs) with the medical and financial consequences are enormous. Polypharmacy (PP) is defined as the concomitant use of 5 or more medications. We studied PP among chronic elderly patients in Gaza Strip and its distri- bution among primary health care clinics in different areas. Materials and Methods: This study is a descriptive analytical study, analyzing prescription data from general practices during a 3-month time period, to measure the prevalence of PP and medication errors among chronic elderly pa- tients. Data were collected directly from the prescriptions and medical records, which contain per- sonal data for patients like patient age and gender, included the current illness, drug treatment for the current illness, chronic disease/s and drug treatment for chronic disease/s. SPSS software was used to analyze the obtained data. Results: Percent of major PP was the highest among patients aged 60 - 69 years when compared with other ages categories of study population but not reached to be statisticaly significant (0.012). Major PP was higher in female patients than that in male patients but difference wasn’t statistically significant (0.5). The average number of drug per prescription was 3.4 drug;and the minimum value per prescription was 1 meanwhile maximum value was 9 (SD + 1.7). Conclusion: PP (use of five drugs or more) is more prevalent among elderly patients with multiple diseases. Female patients consume more drugs than male do. There were some regional differences in drug utilization not explained by morbidity, suggesting some varia- tions in prescribing behaviors.

Risk factors for post-hepatectomy liver dysfunction in primary liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis

Objective:The purpose of this study was to analyze risk factors for development of post-hepatectomy liver dysfunction in primary liver cancer(PLC)patients with concurrent hepatic schistosomiasis and chronic hepatitis.Methods:A retrospective analysis of 73 PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis,of which 16 patients developed liver dysfunction(persistent ascites or pleural effusion or occurrence of liver-related potentially fatal complications)following hepatectomy,was performed.After clinical characteristics were recorded,preoperative liver function parameters and surgery-related parameters in these patients were assessed.Seventeen potential risk factors for post-hepatectomy liver dysfunction were identified.The association between these potential risk factors and post-hepatectomy liver dysfunction then was analyzed.Results:Univariate analysis showed that liver cirrhosis,intraoperative blood loss,and preoperative total bilirubin were associated with the development of post-hepatectomy liver dysfunction.Multivariate logistic regression analysis of these three factors revealed that intraoperative blood loss≥600 mL and cirrhosis were two independent risk factors for post-hepatectomy liver dysfunction in PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis.Conclusion:Keeping intraoperative blood loss below 600 mL can help avoid the development of post-hepatectomy liver dysfunction in liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis.For patients with concomitant liver cirrhosis,every effort should be made to minimize potential liver function impairment induced by other adverse factors.

Staged Revascularization for Chronic Total Occlusion in the Non-IRA in Patients with ST-segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention:An Updated Systematic Review and Meta-analysis

Objectives:Meta-analysis was performed to evaluate the effect of staged revascularization with concomitant chronic total occlusion(CTO)in the non-infarct-associated artery(non-IRA)in patients with ST-segment elevation myocardial infarction(STEMI)treated with primary percutaneous coronary intervention(p-PCI).Methods:Various electronic databases were searched for studies published from inception to June,2021.The primary endpoint was all-cause death,and the secondary endpoint was a composite of major adverse cardiac events(MACEs).Odds ratios(ORs)were pooled with 95%confidence intervals(CIs)for dichotomous data.Results:Seven studies involving 1540 participants were included in thefinal analysis.Pooled analyses revealed that patients with successful staged revascularization for CTO in non-IRA with STEMI treated with p-PCI had overall lower all-cause death compared with the occluded CTO group(OR,0.46;95%CI,0.23–0.95),cardiac death(OR,0.43;95%CI,0.20–0.91),MACEs(OR,0.47;95%CI,0.32–0.69)and heart failure(OR,0.57;95%CI,0.37–0.89)com-pared with the occluded CTO group.No significant differences were observed between groups regarding myocardial infarction and repeated revascularization.Conclusions:Successful revascularization of CTO in the non-IRA was associated with better outcomes in patients with STEMI treated with p-PCI.

Research Progress on Chinese Medicine Immunomodulatory Intervention for Chronic Primary Immune Thrombocytopenia: Targeting Cellular Immunity

Chronic primary immune thrombocytopenia(CITP) is the most common acquired autoimmune disease that seriously threaten the physical and mental health of patients. Compared with Western medicine treatment, the intervention and treatment of Chinese medicine(CM) has shown certain therapeutic advantages. This paper reviewed the new pathogenesis progress on T cell immune abnormality in CITP, and CM studies on interferes effects of cellular immune regulation of CITP in recent years. Qi deficiency failing to control blood and internal obstruction of blood stasis are the two common types of CM syndromes in CITP patients, the corresponding treatments include invigorating Pi(Spleen), supplementing qi, activating blood, as well as tonifying qi and activating yang, regulating Gan(Liver) to invigorate Pi. The authors also mentioned the problems in the research field of CM for CTIP treatment, and put forward new ideas for the research in the future.
