Postoperative chemoradiotherapy with capecitabine and oxaliplatin vs.capecitabine for pathological stage N2 rectal cancer

Objective:Several studies have been conducted on the effects and toxicity of adding oxaliplatin to fluorouracilbased or capecitabine-based chemoradiotherapy(CRT)regimens as significantly increasing the toxic response without benefit to survival.In this study,we further explored the role of these two postoperative CRT regimens in patients with pathological stage N2 rectal cancer.Methods:This study was a subgroup analysis of a randomized clinical trial.A total of 180 patients with pathological stage N2 rectal cancer were eligible,85 received capecitabine with radiotherapy(RT),and 95 received capecitabine and oxaliplatin with RT.Patients in both groups received adjuvant chemotherapy[capecitabine and oxaliplatin(XELOX);or fluorouracil,leucovorin,and oxaliplatin(FOLFOX)]after CRT.Results:At a median follow-up of 59.2[interquartile range(IQR),34.0−96.8]months,the three-year diseasefree survival(DFS)was 53.3%and 64.9%in the control group and the experimental group,respectively[hazard ratio(HR),0.63;95%confidence interval(95%CI),0.41−0.98;P=0.04].There was no significant difference between the groups in overall survival(OS)(HR,0.62;95%CI,0.37−1.05;P=0.07),the incidence of locoregional recurrence(HR,0.62;95%CI,0.24−1.64;P=0.33),the incidence of distant metastasis(HR,0.67;95%CI,0.42−1.06;P=0.09)and grade 3−4 acute toxicities(P=0.78).For patients with survival longer than 3 years,the conditional overall survival(COS)was significantly better in the experimental group(HR,0.39;95%CI,0.16−0.96;P=0.03).Conclusions:Our results indicated that adding oxaliplatin to capecitabine-based postoperative CRT is safe and effective in patients with pathological stage N2 rectal cancer.

Using multi-omics analysis to explore diagnostic tool and optimize drug therapy selection for patients with glioma based on cross-talk gene signature

Background:The heterogeneity of prognosis and treatment benefits among patients with gliomas is due to tumor microenvironment characteristics.However,biomarkers that reflect microenvironmental characteristics and predict the prognosis of gliomas are limited.Therefore,we aimed to develop a model that can effectively predict prognosis,differentiate microenvironment signatures,and optimize drug selection for patients with glioma.Materials and Methods:The CIBERSORT algorithm,bulk sequencing analysis,and single-cell RNA(scRNA)analysis were employed to identify significant cross-talk genes between M2 macrophages and cancer cells in glioma tissues.A predictive model was constructed based on cross-talk gene expression,and its effect on prognosis,recurrence prediction,and microenvironment characteristics was validated in multiple cohorts.The effect of the predictive model on drug selection was evaluated using the OncoPredict algorithm and relevant cellular biology experiments.Results:A high abundance of M2 macrophages in glioma tissues indicates poor prognosis,and cross-talk between macrophages and cancer cells plays a crucial role in shaping the tumor microenvironment.Eight genes involved in the cross-talk between macrophages and cancer cells were identified.Among them,periostin(POSTN),chitinase 3 like 1(CHI3L1),serum amyloid A1(SAA1),and matrix metallopeptidase 9(MMP9)were selected to construct a predictive model.The developed model demonstrated significant efficacy in distinguishing patient prognosis,recurrent cases,and characteristics of high inflammation,hypoxia,and immunosuppression.Furthermore,this model can serve as a valuable tool for guiding the use of trametinib.Conclusions:In summary,this study provides a comprehensive understanding of the interplay between M2 macrophages and cancer cells in glioma;utilizes a cross-talk gene signature to develop a predictive model that can predict the differentiation of patient prognosis,recurrence instances,and microenvironment characteristics;and aids in optimizing the application of trametinib in glioma patients.

Prognostic characterization of copper death-related immune checkpoint genes and analysis of immunologic and pharmacologic therapy in bladder cancer

Objective:Copper death-induced tumor cell death and immune checkpoint blockade therapy are highly selective.Combining their advantages and understanding their characteristics in bladder cancer is very important for the development of new targeted therapy.The identification of bladder cancer by screening the characteristic genes of copper death-related immune checkpoints provide a theoretical basis for the selection of adjuvant treatment options and the application of new targets.Methods:The expression samples of normal bladder tissue and bladder cancer were obtained from TCGA and GEO databases,and 13 cop-per death genes and 79 immune checkpoint genes were extracted from previous studies.The mRNA expression of prognostic genes was verified by qPCR.The copper death-related immune checkpoint genes were screened by correlation analysis to construct a prognostic model,and the differences in the efficacy of immunotherapy and chemotherapy between the high-risk group and the low-risk group were evaluated.Results:A prognostic model consisting of BTNL9,CD160,TNFRSF14 and TNFRSF18 was constructed.Its reliable predictive ability was proved in both databases,and qPCR showed that the expression levels of the four genes were significantly different between the normal group and the cancer cell group.The effect of immunotherapy in the lowrisk group was better than that in the high-risk group.Patients in the high-risk group had better chemotherapy efficacy.Conclusion:The copper death-related immune checkpoint gene model can accurately predict the prognosis of patients.Drug and immune analysis provide a basis for clinical treatment,and the discovery of potential targets provides a new solution for clinical decision-making.

Current status of drug therapy for alveolar echinococcosis

Alveolar echinococcosis(AE)is a chronic zoonotic parasitic disease caused by infection with Echinococcus multilocularis.AE is associated with a high mortality rate and poses a significant threat to human health.The primary treatment for AE is surgical resection of the lesions;however,owing to its long incubation period and insidious disease progression,many patients are diagnosed only after the onset of complications such as liver cirrhosis,jaundice,and portal hypertension,which preclude curative surgical intervention.For patients who are unwilling or unable to undergo surgery,lifelong administration of anti-AE medications is necessary.Benzimidazole compounds,such as albendazole and mebendazole,are the current mainstays of treatment,offering good efficacy.Nevertheless,these medications primarily inhibit parasite proliferation rather than eradicate the infection,and their long-term use can lead to significant drug-related toxic effects.Consequently,there is an urgent need to develop new therapeutic strategies that convey better efficacy and reduce the adverse effects associated with current treatments.Recent advancements in AE therapy include novel synthetic compounds such as antiviral agents,antibiotics,antineoplastic agents,immunosuppressants,and antiangiogenic agents,as well as natural compounds derived from traditional Chinese and Tibetan medicine.These new drugs show promising clinical potential because they interfere with parasitic metabolic pathways and cellular structures.This review aims to discuss recent research on AE drug therapy,including mechanisms of action,dosing regimens,signalling pathways,and therapeutic outcomes,with a goal of providing new insights and directions for the development of anti-AE drugs and summarizing current advancements in AE pharmacotherapy.

Continuing episodes of pain in recurrent acute pancreatitis: Prospective follow up on a standardised protocol with drugs and pancreatic endotherapy

AIM To assess the outcomes of drug therapy(DT)followed by pancreatic endotherapy for continuing painful episodes in recurrent acute pancreatitis.METHODS DT comprised of pancreatic enzymes and antioxidants failing which,endotherapy(ET;pancreatic sphincterotomy and stent placement)was done.The frequency of pain,its visual analogue score(VAS),quality of life(Qo L),serum C peptide and faecal elastase were compared between baseline and after 1 year of follow up in all patients and in the two subgroups on DT and ET.Response was defined as at least 50%reduction in the severity of pain to below a score of 5.RESULTS Of the thirty nine patients analysed,21(53.9%)responded to DT and 18(46.1%)underwent ET.The VAS for pain(7.0±2.0 vs 1.3±2.5,P<0.001)and the number of days with pain per month decreased[1.0(1.0,2.0)vs 1.0(0.0,1.0),P<0.001],and the Qo L scores[55.0(44.0,66.0)vs 38.0(32.00,51.00),P<0.01]improved significantly during follow up.Similar significant improvements were seen in patients in the subgroups of DT and ET except for Qo L in ET.The serum C-peptide(P=0.001)and FE(P<0.001)levels improved significantly in the entire group and in the two subgroups of patients except for the C peptide levels in patients on DT.CONCLUSION A standardised protocol of DT,followed by ET decreased the intensity and frequency of pain in recurrent acute pancreatitis,enhanced Qo L and improved pancreatic function.

Immunotherapy for recurrent hepatocellular carcinoma

Hepatocellular carcinoma(HCC)is presented frequently in late stages that are not amenable for curative treatment.Even for patients who can undergo resection for curative treatment of HCC,up to 50%recur.For patients who were not exposed to systemic therapy prior to recurrence,recurrence frequently cannot be subjected to curative therapy or local treatments.Such patients have several options of immunotherapy(IO).This includes programmed cell death protein 1(PD-1)and cytotoxic T-lymphocyte associated protein 4 treatment,combination of PD-1 and vascular endothelial growth factor inhibitor or single agent PD-1 therapy when all other options are deemed inappropriate.There are also investigational therapies in this area that explore either PD-1 and tyrosine kinase inhibitors or a novel agent in addition to PD-1 with vascular endothelial growth factor inhibitors.This minireview explored IO options for patients with recurrent HCC who were not exposed to systemic therapy at the initial diagnosis.We also discussed potential IO options for patients with recurrent HCC who were exposed to first-line therapy with curative intent at diagnosis.

Pharmacological interventions targeting the microcirculation following traumatic spinal cord injury

Traumatic spinal cord injury is a devastating disorder chara cterized by sensory,motor,and autonomic dysfunction that seve rely compromises an individual's ability to perform activities of daily living.These adve rse outcomes are closely related to the complex mechanism of spinal cord injury,the limited regenerative capacity of central neurons,and the inhibitory environment fo rmed by traumatic injury.Disruption to the microcirculation is an important pathophysiological mechanism of spinal cord injury.A number of therapeutic agents have been shown to improve the injury environment,mitigate secondary damage,and/or promote regeneration and repair.Among them,the spinal cord microcirculation has become an important target for the treatment of spinal cord injury.Drug inte rventions targeting the microcirculation can improve the microenvironment and promote recovery following spinal cord injury.These drugs target the structure and function of the spinal cord microcirculation and are essential for maintaining the normal function of spinal neuro ns,axons,and glial cells.This review discusses the pathophysiological role of spinal cord microcirculation in spinal cord injury,including its structure and histopathological changes.Further,it summarizes the progress of drug therapies targeting the spinal cord mic rocirc ulation after spinal cord injury.

Efficacy and Safety of Iron Isomaltoside Compared with an Oral Iron Supplement in the Management of Patients with Iron Deficiency Anemia

Objective: To evaluate the treatment outcome of iron isomaltoside compared with an oral iron supplement in the management of iron deficiency anemia (IDA). Methods: The study included patients with IDA who visited the Outpatient Clinic of the Department of Hematology, the Affiliated Hospital of Qingdao University from October 2021 to August 2022 and met the inclusion and exclusion criteria. According to the actual application of iron supplementation, the patients were divided into two groups: iron isomaltoside treatment group and oral iron treatment group. Baseline measurements were collected before the start of treatment, and measurements were collected subsequently at intervals of 1 week, 1 month, and 3 months. The hematological parameters analyzed included Hemoglobin (Hb), Mean corpuscular hemoglobin (MCH), Mean Hemoglobin content (MCH), Mean corpuscular Hemoglobin concentration (MCHC), and Platelet (Plt). Safety data and adverse event profiles were recorded. Results: Intra-group comparisons: After 1 month of treatment, the Hb significantly improved (P 0.05). Inter-group comparisons: The biochemical parameters were significantly improved (P 0.05) in the iron isomaltoside group compared with those in the oral iron group after 1 month of iron supplementation in patients with mild and moderate anemia. Adverse reactions were tolerable for the patients in both iron isomaltoside group and oral iron group. Only 1 patient in iron isomaltoside group developed anaphylactic shock during medication and recovered after aggressive rescue. Conclusions: Iron isomaltoside which increases Hb more rapidly compared with the oral iron supplementation has few adverse reactions and good acceptance.

Long-term alpha interferon and lamivudine combination therapy in non-responder patients with anti-HBe-positive chronic hepatitis B:Results of an open,controlled trial

AIM: To investigate the safety and efficacy of long-term combination therapy with alpha interferon and lamivudine in non-responsive patients with anti-HBe-positive chronic hepatitis B.METHODS: 34 patients received combination treatment (1 month lamivudine, 12 month lamivudine+interferon, 6month lamivudine), 24 received lamivudine (12 months),24 received interferon (12 months). Interferon was administered at 6 MU tiw and lamivudine at 100 mg orally once daily. Patients were followed up for 6 months after treatment.RESULTS: At the end of treatment, HBV DNA negativity rates were 88 % with lamivudine+interferon, 99 % with lamivudine and 55 % with interferon, (P=0.004, combination therapy vs. interferon, and P=0.001 lamivudine vs.interferon), and serum transaminase normalization rates were 84 %, 91% and 53 % (P=0.01 combination therapy vs. interferon, and P=0.012 lamivudine vs. interferon). Six months later, HBV DNA negativity rates were 44 % with lamivudine+interferon, 33 % with lamivudine and 25 % with interferon, and serum transaminase normalization rates were 61%, 42 % and 45 %, respectively, without statistical significance. No YMDD variants were observed with lamivudine+interferon (vs. 12 % with lamivudine). The combination therapy appeared to be safe. CONCLUSION: Although viral clearance and transaminase normalization are slower with long-term lamivudine+interferon than that with lamivudine alone, the combination regimen seems to provide more lasting benefits and to protect against the appearance of YMDD variants. Studies with other regimens regarding sequence and duration are needed.

Advances in Drug Therapy for Alzheimer’s Disease

Alzheimer’s disease(AD)is a chronic neurodegenerative disease that mainly causes dementia.It is a serious threat to the health of the global elderly population.Considerable money and effort has been invested in the development of drug therapy for AD worldwide.Many drug therapies are currently under development or in clinical trials,based on two known mechanisms of AD,namely,Aβtoxicity and the abnormal Tau hyperphosphorylation.Numerous drugs are also being developed for other AD associated mechanisms such as neuroinflammation,neurotransmitter imbalance,oxidative damage and mitochondrial dysfunction,neuron loss and degeneration.Even so,the number of drugs that can successfully improve symptoms or delay the progression of the disease remains very limited.However,multi-drug combinations may provide a new avenue for drug therapy for AD.In addition,early diagnosis of AD and timely initiation of treatment may allow drugs that act on the early pathological processes of AD to help improve the symptoms and prevent the progression of the condition.

Azithromycin-containing versus standard triple therapy for Helicobacter pylori eradication:A meta-analysis

AIM： To evaluate whether adding azithromycin to firstline Helicobacter pylori （H pylorl） eradication improved eradication and reduced side effects. METHODS： Eligible articles were identified by searches of electronic databases. We included all randomized trials that compared azithromycin-containing with standard triple-therapy regimens for first-line treatment of H pylori infection. Statistical analysis was performed with Review Manager 5.0.10. Sub-analyses were also performed. RESULTS： We identified 14 randomized trials （1431 patients）. Pooled Hpylori eradication rates were 72.01% （95% CI： 58.09%-85.93%） and 69.78% （95% CI： 66.47%-73.09%） for patients with or without azithromycin by intention-to-treat analysis, and the odds ratio （OR） was 1.17 （95% CI： 0.64-2.14）. The occurrence of side effects differed significantly and was 15.81% （95% CI： 12.50%-19.12%） and 25.20% （95% CI： 21.44%-28.96%） for treatment with or without azithromycin, respectively, and the summary OR was 0.58 （95% CI： 0.41-0.82）. Furthermore, the azithromycin-containing group had a lower occurrence of diarrhea, nausea and taste disturbance. CONCLUSION： Our review suggests that azithromycincontaining triple-therapy regimens could be equally effective in eradication of Hpylori compared with standard first-line triple-therapy regimens.

Low eradication rate of Helicobacterpyloriwith triple 7-14 days and quadriple therapy in Turkey

AIM:The eradication rate of Helicobacter pylori (H pylori) shows variation among countries and regimens of treatment. We aimed to study the eradication rates of different regimens in our region and some factors affecting the rate of eradication. METHODS:One hundred and sixty-four H pylori positive patients (68 males,96 females;mean age:48±12 years) with duodenal or gastric ulcer without a smoking history were included in the study.The patients were divided into three groups according to the treatment regimens.Omeprazole 20mg,clarithromycin 500mg,amoxicillin 1g were given twice daily for 1 week (Group Ⅰ) and 2 weeks (Group Ⅱ). Patients in Group Ⅲ received bismuth subsitrate 300mg, tetracyline 500mg and metronidazole 500mg four times daily in addition to Omeprazole 20mg twice daily.Two biopsies each before and after treatment were obtained from antrum and corpus,and histopathologically evaluated. Eradication was assumed to be successful if no H pylorus was detected from four biopsy specimens taken after treatment.The effects of factors like age,sex,H pylori density on antrum and corpus before treatment,the total H pylori density,and the inflammation scores on the rate of H pylori eradication were evaluated. RESULTS:The overall eradication rate was 42%.The rates in groups Ⅱ and Ⅲ were statistically higher than that in group Ⅰ (P<0.05).The rates of eradication were 24.5%, 40.7% and 61.5% in groups Ⅰ,Ⅱ and Ⅲ,respectively.The eradication rate was negatively related to either corpus H pylori density or total H pylori density (P<0.05).The median age was older in the group in which the eradication failed in comparison to that with successful eradication (55 yr vs 39 yr,P<0.001).No correlation between sex and H pylori eradication was found. CONCLUSION:Our rates of eradication were significantly lower when compared to those reported in literature.We believe that advanced age and high H pylori density are negative predictive factors for the rate of H pylori eradication.

Azithromycin in a triple therapy for H.pylori eradication in active duodenal ulcer

AIM:To assess and compare the efficacy and safety of two triple regimes:A)metronidazole,amoxicillin and omeprazole, which is still widely used in Russia,and B)azithromycin, amoxicillin and omeprazole in healing active duodenal ulcer and H.pylori eradication. METHODS:100 patients with active duodenal ulcer were included in the open,multicentre,randomized study with comparative groups.Patients were randomly assigned to one of the following one-week triple regimes:A) metronidazole 500 mg bid,amoxicillin I g bid and omeprazole 20 mg bid(OAM,n=50)and B)azithromycin 1 god for the first 3 days(total dose 3 g),amoxicillin 1 g bid and omeprazole 20 mg bid(OAA,n=50).Omeprazole 20 mg od was given after the eradication course as a monotherapy for three weeks.The control endoscopy was performed 8 weeks after the entry.H.pyloriinfection was determined in the entry of the study and four weeks after the cessation of treatment by means of histology and CLO-test. RESULTS:97 patients completed the study according to the protocol(1 patient of the OAM group did not come to the control endoscopy,2 patients of the OAA group stopped the treatment because of mild allergic urticaria).Duodenal ulcers were healed in 48 patients of the OAM group(96 %, C190.5-100 %)and in 46 patients of the OAA group(92 %, CI 89.5-94.5 %)(p=ns).H.pyloHinfection was eradicated in 15 out of 50 patients with OAM(30 %,CI 17-43 %)and in 36 out of 50 patients treated with OAA(72 %;CI 59-85 %) (P<0.001)-ITT analysis.CONCLUSION: The triple therapy with omeprazole, amoxicillin and metronidazole failed to eradicate H.pylori'vc\ the majority of patients, which is an essential argument to withdraw this regimen out of the national recommendations. Macrolide with amoxicillin are preferable to achieve higher eradication rates. Azithromycin (1 g od for the first 3 days) can be considered as a successful component of the triple PPI-based regimen.

Applications and developments of gene therapy drug delivery systems for genetic diseases

Genetic diseases seriously threaten human health and have always been one of the refractory conditions facing humanity.Currently,gene therapy drugs such as siRNA,shRNA,antisense oligonucleotide,CRISPR/Cas9 system,plasmid DNA and miRNA have shown great potential in biomedical applications.To avoid the degradation of gene therapy drugs in the body and effectively deliver them to target tissues,cells and organelles,the development of excellent drug delivery vehicles is of utmost importance.Viral vectors are the most widely used delivery vehicles for gene therapy in vivo and in vitro due to their high transfection efficiency and stable transgene expression.With the development of nanotechnology,novel nanocarriers are gradually replacing viral vectors,emerging superior performance.This review mainly illuminates the current widely used gene therapy drugs,summarizes the viral vectors and non-viral vectors that deliver gene therapy drugs,and sums up the application of gene therapy to treat genetic diseases.Additionally,the challenges and opportunities of the field are discussed from the perspective of developing an effective nano-delivery system.

Evaluation of menopausal status among breast cancer patients with chemotherapy-induced amenorrhea

Objective： In patients with chemotherapy-induced amenorrhea （CIA）, the menopausal status is ambiguous anddifficult to evaluate. This study aimed to establish a discriminative model to predict and classify the menopausalstatus of breast cancer patients with CIA.Methods： This is a single center hospital-based study from 2013 to 2016. The menopausal age distribution andaccumulated incidence rate of CIA are described. Multivariate models were adjusted for established and potentialconfounding factors including age, serum concentration of estradiol （E2） and follicle-stimulating hormone （FSH）,feeding, pregnancy, parity, abortions, and body mass index （BMI）. The odds ratio （OR） and 95% confidenceinterval （95% CI） of different risk factors were estimated.Results： A total of 1,796 breast cancer patients were included in this study, among whom, 1,175 （65.42%） werepremenopausal patients and 621 （34.58%） were post-menopause patients. Five hundred and fifty patients wereincluded in CIA analysis, and a cumulative CIA rate of 81.64% was found in them. Age （OR： 1.856, 95% CI：1.732-1.990）, serum concentration of E2 （OR： 0.976, 95% CI： 0.972-0.980） and FSH （OR： 1.060, 95% CI：1.053-i.066）, and menarche age （OR： 1.074, 95% CI： 1.009-1.144） were found to be associated with the patients＇menopausal status. According to multivariate analysis, the discriminative model to predict the menopausal status isLogit （P）=-28.396＋0.536Age-0.014E2＋0.031FSH. The sensitivities for this model were higher than 85%, and itsspecificities were higher than 89%.Conclusions： The discriminative model obtained from this study for predicting menstrual state is important forpremenopausal patients with CIA. This model has high specificity and sensitivity and should be prudently used.

Medical therapy for clinical benign prostatic hyperplasia:α1 Antagonists,5α reductase inhibitors and their combination

Medical therapy for clinical benign prostatic hyperplasia(BPH)has advanced significantly in the last 2 decades.Many new a1 antagonists and 5a reductase inhibitors(5ARi)are now commercially available.The practicing urologist must decide on the most appropriate medication for his patients,taking into consideration various factors like efficacy,dosing regime,adverse effects,cost,patient’s socioeconomic background,expectations,drug availability and his own clinical experience.The use of combination therapy added further to the complexity in clinical judgment when prescribing.We highlight some of the key points in prescribing a1 antagonists,5ARi and their combination,based on our viewpoints and experience as urologists in an Asian clinical setting.
