Research progress of local characteristic drugs for treatment of rheumatoid arthritis in Xinjiang

Rheumatoid arthritis(RA)is a systemic autoimmune disease characterized by synovitis.This disease tends to recur,persist,and is difficult to cure.The pathogenesis of RA is complex.Currently,the commonly used treatments for RA—non-steroidal anti-inflammatory drugs(NSAIDs),disease-modifying anti-rheumatic drugs(DMARDs),glucocorticoids,and immunosuppressants—have notable side effects with long-term use and may be ineffective for some patients.Therefore,it is crucial to find drugs with limited side effects and significant curative effects.Xinjiang's local characteristic drugs have a long history,abundant resources,and are known for their safety and effectiveness in treating RA.In recent years,many studies have reported on the mechanisms of action and therapeutic effects of Xinjiang's local characteristic drugs on RA.This article reviews the pathogenesis of RA,as well as the research progress and treatment characteristics of Xinjiang-featured drugs.

Compared efficacy of University of Wisconsin and histidine-tryptophan-ketoglutarate solutions in ex-situ liver resection and autotransplantation for end-stage hepatic alveolar echinococcosis patients

Background: The University of Wisconsin (UW) and histidine-tryptophan-ketoglutarate (HTK) solutions are the two most frequently used liver graft preservation fluids. The present study aimed to compare their efficacy in end-stage hepatic alveolar echinococcosis patients who underwent ex-situ liver resection and autotransplantation (ELRA). Methods: A total of 81 patients received ELRA from August 2010 to March 2018. They were allocated into UW ( n = 48) and HTK groups ( n = 33) based on the type of solutions used. Demographic and operational data were retrospectively analyzed. Primary outcomes included 90-day mortality, incidence of early graft loss, primary dysfunction, and postoperative complications. Results: Demographic and operational characteristics were similarly distributed in the two groups. No statistically significant differences were observed with regard to 90-day mortality (12.77% vs. 12.12%) and early graft loss rate (8.51% vs. 9.09%) between the two groups. Patients in the UW and HTK groups showed a primary dysfunction rate of 27.66% and 27.27%, respectively. The UW group exhibited a higher incidence tendency of biliary complications, albeit with no statistical significance. Conclusions: This is the largest cohort study comparing the efficacy of the UW and HTK organ-preserving solutions in end-stage hepatic alveolar echinococcosis patients in ELRA settings. UW and HTK solutions presented similar efficacy and safety. A randomized clinical trial with larger scale is needed for further investigation in future clinical applications.

BACKGROUND Traumatic amputation of the penis is a rare surgical emergency,usually caused by self-mutilation,accidents,circumcision,assault and animal attacks.This study aimed to summarize our treatment experience involving penile reconstruction in a rare case of a self-strangulation induced chronical penile partial amputation.CASE SUMMARY A 22-year-old man presented with self-strangulation induced chronical penile partial amputation for 3 mo where the penile proximal part was 1 cm far from the pubis.Reconstruction methods included end-to-end anastomosis of the urethral mucosa,proximal anastomosis of the corpus cavernosum and tunica albuginea of the penis,anastomosis of the deep dorsal vein,dorsal artery,and superficial dorsal vein.Patient urinated smoothly after the catheter was removed on day 21.3 mo after the surgery,the patient's penile preliminary cosmetic appearance was satisfactory,with occasional morning erections.Distal penile sensation was preserved,yet erection hardness of the distal penis was not satisfactory.CONCLUSION Complete preoperative assessment and prompt surgical intervention decreases loss of residual penile functions.

Human papillomavirus distribution and cervical cancer epidemiological characteristics in rural population of Xinjiang,China

Background:Cervical cancer remains a major public health issue for the Uyghur women and other women living mainly in rural areas of Xinjiang.This study aims to investigate the distribution of human papillomavirus(HPV)infection and cervical cancer in rural areas of Xinjiang,China.Methods:Cervical cancer screening was performed on rural women aged 35 to 64 years from Xinjiang,China in 2017 through gynecological examination,vaginal discharge smear microscopy,cytology,and HPV testing.If necessary,colposcopy and biopsy were performed on women with suspicious or abnormal screening results.Results:Of the 216,754 women screened,15,518 received HPV testing.The HPV-positive rate was 6.75%(1047/15,518).Compared with the age 35-44 years group,the odds ratios(ORs)of HPV positivity in the age 45-54 years and 55-64 years groups were 1.18(95%confidence interval[Cl]:1.02-1.37)and 1.84(95%Cl:1.53-2.21),respectively.Compared with women with primary or lower education level,the ORs for HPV infection rates of women with high school and college education or above were 1.37(95%Cl:1.09-1.72)and 1.62(95%Cl:1.23-2.12),respectively.Uyghur women were less likely to have HPV infection than Han women,with an OR(95%Cl)of 0.78(0.61-0.99).The most prevalent HPV types among Xinjiang women were HPV 16(24.00%),HPV 33(12.70%),and HPV 52(11.80%).The detection rate of cervical intraepithelial neoplasia(CIN)2+was 0.14%and the early diagnosis rate of cervical cancer was 85.91%.The detection rates of vaginitis and cervicitis were 19.28%and 21.32%,respectively.Conclusions:The HPV infection rate in Xinjiang is low,but the detection rate of cervical cancer and precancerous lesions is higher than the national average level.Cervical cancer is a prominent public health problem in Xinjiang,especially in southern Xinjiang.

The pathologic relevance of metabolic criteria in patients with biopsy-proven nonalcoholic fatty liver disease and metabolic dysfunction associated fatty liver disease:A multicenter cross-sectional study in China

Background:This study aimed to assess the association between metabolic syndrome(Met S)and severity of nonalcoholic fatty liver disease(NAFLD),and to discuss the pathological relevance of the diagnostic criteria in metabolic(dysfunction)associated fatty liver disease(MAFLD).Methods:This was a multicenter,cross-sectional study.Patients with NAFLD confirmed by liver biopsy were enrolled between July 2016 and December 2018 from 14 centers across the mainland of China.Anthropometric and metabolic parameters were collected to assess the pathological relevance.Results:Of 246 enrolled patients with NAFLD,150(61.0%)had the comorbidity of Met S.With the increase of metabolic components,the proportions of nonalcoholic steatohepatitis(NASH)and significant fibrosis were notably increased.The comorbid three metabolic components significantly increased the proportion of NASH,and further increase of metabolic components did not increase the proportion of NASH.However,the increase of metabolic components was parallel to the increase of the proportion of liver fibrosis.Among the 246 patients,239(97.2%)met the diagnostic criteria of MAFLD.Although non-MAFLD patients had less NASH,they present with similar proportion of significant fibrosis and cirrhosis.In the diagnostic criteria of MAFLD,BMI≥23 kg/m2 was related to NASH(Mantel-Haenszel Common Estimate OR:2.975;95%CI:1.037–8.538;P=0.043),and T2 DM was related to significant fibrosis(Mantel-Haenszel Common Estimate OR:2.531;95%CI:1.388–4.613;P=0.002).The homeostasis model assessment of insulin resistance(HOMA-IR)≥2.5 was the most significant factor for NASH(OR:4.100;95%CI:1.772–9.487;P=0.001)and significant factor for liver fibrosis(OR:2.947;95%CI:1.398–6.210;P=0.004)after the adjustments of the BMI and diabetes.Conclusions:Metabolic dysregulations are important risk factors in NAFLD progression.The insulin resistance status may play a predominant role in the progression in MAFLD patients.

lncRNA AC005224.4/miR-140-3p/SNAI2 regulating axis facilitates the invasion and metastasis of ovarian cancer through epithelial-mesenchymal transition

Background:Ovarian cancer is one of the most widespread malignant diseases of the female reproductive system worldwide.The plurality of ovarian cancer is diagnosed with metastasis in the abdominal cavity.Epithelial-mesenchymal transition(EMT)exerts a vital role in tumor cell metastasis.However,it remains unclear whether long non-coding RNA(lncRNA)are implicated in EMT and influence ovarian cancer cell invasion and metastasis.This study was designed to investigate the impacts of lncRNA AC005224.4 on ovarian cancer.Methods:LncRNA AC005224.4,miR-140-3p,and snail family transcriptional repressor 2(SNAI2)expression levels in ovarian cancer and normal ovarian tissues were determined using real-time quantitative polymerase chain reaction(qRT-PCR).Cell Counting Kit-8(CCK-8)and Transwell(migration and invasion)assays were conducted to measure SKOV3 and CAOV-3 cell proliferation and metastasis.E-cadherin,N-cadherin,Snail,and Vimentin contents were detected using Western blot.Nude mouse xenograft assay was utilized to validate AC005224.4 effects in vivo.Dual-luciferase reporter gene assay confirmed the targeted relationship between miR-140-3p and AC005224.4 or SNAI2.Results:AC005224.4 and SNAI2 upregulation and miR-140-3p downregulation were observed in ovarian cancer tissues and cells.Silencing of AC005224.4 observably moderated SKOV3 and CAOV-3 cell proliferation,migration,invasion,and EMT process in vitro and impaired the tumorigenesis in vivo.miR-140-3p was a target of AC005224.4 and its reduced expression level was mediated by AC005224.4.miR-140-3p mimics decreased the proliferation,migration,and invasion of ovarian cancer cells.SNAI2 was identified as a novel target of miR-140-3p and its expression level was promoted by either AC005224.4 overexpression or miR-140-3p knockdown.Overexpression of SNAI2 also facilitated ovarian cancer cell viability and metastasis.Conclusion:AC005224.4 was confirmed as an oncogene via sponging miR-140-3p and promoted SNAI2 expression,contributing to better understanding of ovarian cancer pathogenesis and shedding light on exploiting the novel lncRNA-directed therapy against ovarian cancer.

New Algorithm Rules Out Acute-on-chronic Liver Failure Development within 28 Days from Acute Decompensation of Cirrhosis

Background and Aims:Approximately 10%of patients with acute decompensated(AD)cirrhosis develop acute-on-chronic liver failure(ACLF)within 28 days.Such cases have high mortality and are difficult to predict.Therefore,we aimed to establish and validate an algorithm to identify these patients on hospitalization.Methods:Hospitalized patients with AD who developed ACLF within 28 days were considered pre-ACLF.Organ dysfunction was defined accord-ing to the chronic liver failure-sequential organ failure as-sessment(CLIF-SOFA)criteria,and proven bacterial infec-tion was taken to indicate immune system dysfunction.A retrospective multicenter cohort and prospective one were used to derive and to validate the potential algorithm,re-spectively.A miss rate of<5%was acceptable for the calcu-lating algorithm to rule out pre-ACLF.Results:In the deri-vation cohort(n=673),46 patients developed ACLF within 28 days.Serum total bilirubin,creatinine,international normalized ratio,and present proven bacterial infection at admission were associated with the development of ACLF.AD patients with≥2 organ dysfunctions had a higher risk for pre-ACLF patients[odds ratio=16.58195%confidence interval:(4.271-64.363),p<0.001].In the derivation co-hort,67.5%of patients(454/673)had≤1 organ dysfunction and two patients(0.4%)were pre-ACLF,with a miss rate of 4.3%(missed/total,2/46).In the validation cohort,65.9%of patients(914/1388)had≤1 organ dysfunction,and four(0.3%)of them were pre-ACLF,with a miss rate of 3.4%(missed/total,4/117).Conclusions:AD patients with≤1 organ dysfunction had a significantly lower risk of developing ACLF within 28 days of admission and could be safely ruled out with a pre-ACLF miss rate of<5%.

Ex vivo liver resection followed by autotransplantation for end-stage hepatic alveolar echinococcosis

Background For patients with end-stage hepatic alveolar echinococcosis （AE）, in vivo resection of the involved parts of the liver is usually very difficult, therefore, allogenic liver transplantation is indicated. However, we hypothesize that for selected patents, ex vivo liver resection for thorough elimination of the involved tissues and liver autotransplantation may offer a chance for clinical cure. Methods We presented a 24-year-old women with a giant hepatic AE lesion who was treated with hepatectomy, ex vivo resection of the involved tissue and hepatic autotransplantation. The patient had moderate jaundice and advanced hepatic AE lesion which involved segments I, IV, V, VI, VII, VIII and retrohepatic inferior vena cava. The lateral segments （II and III） of the left liver remained normal with over 1000 ml in its volume. No extrahepatic metastases （such as to the lung or brain） could be found. As the first step of treatment, X-ray guided percutaneous transhepatic cholangiodrainage （PTCD） was performed twice for bile drainage in segment III and II separately until her serum total bilirubin decreased gradually from 236 to 88 umol/L. Total liver resection was then performed, followed by extended right hepatic trisegmentectomy and the entire retrohepatic vena cava was surgically removed en bloc while her hemodynamics parameters were stable. Neither veino-veinous bypass nor temporary intracorporeal cavo-caval or porto-caval shunt was used during the 5.7-hour anhepatic phase. The remained AE-free lateral segments of the-left liver were re-implanted in situ. The left hepatic vein was directly anastomosed end-to-end to the suprahepatic inferior vena cava due to the lack of the retrohepatic inferior vena cava with AE total infiltration. Because compensatory retroperitoneal porto-caval collateral circulation developed, we enclosed remained infrahepatic inferior vena cava at renal vein level without any haemodynamics problems. Results During a 60-day following-up after operation, the patient had a good recovery except for a mildly elevated serum total bilirubin. Conclusions As a radical approach, ex vivo liver resection and liver autotransptantation in a case has shown a optimal potential for treatment of the end-stage hepatic AE. Strict compliance with its indications, evaluation of vessels of patients pre-operatively, and precise surgical techniques are the keys to improve the prognosis of patients.

Diagnosis, treatment, and misdiagnosis analysis of 28 cases of central nervous system echinococcosis

Background:To explore central nervous system(CNS)involvement in this disease,from the perspectives of diagnosis,treatment,and misdiagnosis Methods:Twenty-eight patients with CNS echinococcosis were included in this retrospective study,including 18 males(64.3%)and 10(35.7%)females.The average age of all the patients were 23.5 years(ranged 4–60 years).Twenty-three(23)patients(82.1%)received the first surgical resection in our hospital.Five(5)patients(17.9%)gave up surgical treatment for multiple-organ hydatidosis and previous surgery history at other hospitals,and albendazole was applied for a long-term(3–6 months)adjunct therapy for the 5 patients.The average follow-up time was 8 years.Results:For the 28 patients,23 cases received surgical treatments,and the diagnosis was confirmed by pathological examinations.The diagnosis of 4 cases of brain echinococcosis and 2 cases of spinal cord echinococcosis could not be confirmed,resulting in a misdiagnosis rate of 21.4%(6/28).For the pathological examination,a total of 17 cases were infected with Echinococcus granulosus(including 2 cases of spinal cord echinococcosis),and 6 cases were infected with Echinococcus alveolaris.Conclusion:The diagnosis should be specifically considered in endemic regions.The clinical features of CNS hydatidosis were intracranial space-occupying lesions.For the treatment,the surgical removal of cysts should be necessary.In addition,the adjuvant therapy with drug and intraoperative prophylaxis is also suggested.The misdiagnosis may have resulted from atypical clinical features and radiographic manifestations,as well as the accuracy of hydatid immunologic test.

Recent advances in the development of activatable multifunctional probes for in vivo imaging of caspase-3

Caspases are a family of proteases that play critical roles in controlling inflammation and cell death.Apoptosis is a caspase-3 mainly controlled behavior to avoid inflammation and damage to surrounding cells,whereas anomalistic cell apoptosis may be associated with many diseases.The detection and imaging of caspase-3 will be of great significance in evaluating the early therapeutic effect of tumors.Developing smart fluorescent probes may be helpful for the visualization of the rapeutic effect compared with "always on" probes.Thus,more and more works toward activatable fluorescent probes for caspase-3 imaging have been reported.In addition,multifunctional probes have also been designed to further improve the imaging of caspase-3.Herein,this review systematically summarized the representative wo rk of caspase-3 from the perspective of molecular design that it will play a guiding role in the design of probes that respond to caspase-3.Also,challenges and perspectives toward the field for imaging of cell apoptosis(caspase-3) are also discussed.

Using boosting tree to learn imbalanced data

In case of machine learning,the problem of class imbalance is always troubling,i.e.one class of the samples has a larger magnitude than the other classes.This problem brings a preference of the classifier to the majority class,which leads to worse performance of the classifier on the minority class.We proposed an improved boosting tree(BT) algorithm for learning imbalanced data,called cost BT.In each iteration of the cost BT,only the weights of the misclassified minority class samples are increased.Meanwhile,the error rate in the weight formula of the base classifier is replaced by 1 minus F-measure.In this study,the performance of the cost BT algorithm is compared with other known methods on 9 public data sets.The compared methods include the decision tree and random forest algorithm,and both of them were combined with the sampling techniques such as synthetic minority oversampling technique(SMOTE),Borderline-SMOTE,adaptive synthetic sampling approach(ADASYN) and one sided selection.The cost BT algorithm performed better than the other compared methods in F-measure,G-mean and area under curve(AUC).In 6 of the 9 data sets,the cost BT algorithm has a superior performance to the other published methods.It can promote the prediction performance of the base classifiers by increasing the proportion of the minority class in the whole samples with only increasing the weights of the misclassified minority class samples in each iteration of the BT.In addition,computing the weights of the base classifiers with F-measure is helpful to the ensemble decisions.

Comparison of outcomes after human leukocyte antigen-matched and haploidentical hematopoietic stem-cell transplantation for multiple myeloma

Background:Allogeneic stem-cell transplantation (SCT) is a well-established immunotherapeutic strategy for multiple myeloma (MM) with a potent and often sustained graft-vs.-myeloma effect.This multicenter investigation aimed to analyze the complications and survival of haploidentical SCT in patients with MM,and compare the main outcomes with matched-related donors (MRDs).Methods:Haploidentical and MRD SCT was identified from a cohort of 97 patients with MM who received a myeloablative transplantation in 13 hospitals from May 2001 to December 2017.A matched-pair analysis was designed.For each haplo recipient,the recipients were randomly selected from the MRD group and were matched according to the following criteria:year of the hematopoietic SCT (±2 years),disease status at transplantation,and the length of follow-up.ults:Seventy cases received MRD and 27 received haploidendcal transplantation.The two groups showed no significant ifferences regarding age,gender,cytogenetic risk,and diagnostic stage.The cumulative incidences of non-relapse mortality (NRM) at1 and 3 years based on donor type were 20.5%(95% confidence interval [CI],10.90-30.10%) and 24.2%(95% CI,13.81-34.59%) for the MRD group and 16.80%(95% CI,1.71-31.89%) and 28.70%(95% CI,8.71-48.69%) for the haplo group,respectively.Cumulative incidence of NRM did not differ significantly between the two groups (x2 =0.031,P =0.861).The cumulative incidences of progression-free survival (PFS) and 1 year and 3 years by type of donors were 59.8 %(95 % CI,48.24-71.36 %) and 45.4 %(95 % CI,33.44-57.36%),and 65.6%(95% CI,47.18-84.02%) and 26.8%(95% CI,7.59-46.01%) for MRD and haploidentical donor,respectively.Cumulative incidence of PFS did not differ significantly between the two groups (x2 =0.182,P =0.670).In multivariate analyses,no statistically significant differences were observed between haploidentical and MRD for relapse,NRM,PFS,and overall survival.There were no statistically differences on main outcomes after haploidentical and MRD.Conclusion:Haploidentical SCT could be performed safely and feasibly for patients with MM in need.

Analysis of Factors Influencing the Cumulative Pregnancy Outcome of In Vitro Fertilization-Embryo Transfer in Women Aged 35 Years and Older with Normal Ovarian Reserve

Background:To investigate the factors associating with the cumulative clinical pregnancy outcome of in vitro fertilization-embryo transfer(IVF-ET)in women aged 35 years and older with normal ovarian reserve.Methods:A total of 358 patients undergoing IVF-ET at the Department of Reproductive Medicine,the First Affiliated Hospital of Xinjiang Medical University between January 2014 and June 2016 were analyzed by the Kaplan-Meier method and Cox proportional hazards model.Results:The probability of pregnancy in women 35-37 years of age and 38-40 years of age was 75.9%(95%confidence interval[CI]:75.1%-76.7%)and 66.9%(95%CI:65.6%-68.2%),respectively,and it was 37.8%(95%CI:34.7%-41.1%)in women aged 40 years and older.Univariate analysis(hazard ratio[HR]:2.50,95%CI:1.647-3.774)and multivariate analysis(HR:2.17,95%CI:1.427-3.268)showed a correlation between the number of retrieved oocytes and successful pregnancy.Conclusions:The number of retrieved oocytes plays a key role in the pregnancy outcome of women aged 35 years and older with normal ovarian reserve.We recommend the number of retrieved oocytes be increased for women aged 35 years and older with normal ovarian reserve.
