Objective Previous studies on the association between lipid profiles and chronic kidney disease(CKD)have yielded inconsistent results and no defined thresholds for blood lipids. Methods A prospective cohort study including 32,351 subjects who completed baseline and follow-up surveys over 5 years was conducted.Restricted cubic splines and Cox models were used to examine the association between the lipid profiles and CKD.A regression discontinuity design was used to determine the cutoff value of lipid profiles that was significantly associated with increased the risk of CKD. Results Over a median follow-up time of 2.2(0.5,4.2)years,648(2.00%)subjects developed CKD.The lipid profiles that were significantly and linearly related to CKD included total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),TC/HDL-C,and TG/HDL-C,whereas low-density lipoprotein cholesterol(LDL-C)and LDL-C/HDL-C were nonlinearly correlated with CKD.TC,TG,TC/HDL-C,and TG/HDL-C showed an upward jump at the cutoff value,increasing the risk of CKD by 0.90%,1.50%,2.30%,and 1.60%,respectively,whereas HDL-C showed a downward jump at the cutoff value,reducing this risk by 1.0%.Female and participants with dyslipidemia had a higher risk of CKD,while the cutoff values for the different characteristics of the population were different. Conclusion There was a significant association between lipid profiles and CKD in a prospective cohort from Northwest China,while TG,TC/HDL-C,and TG/HDL-C showed a stronger risk association.The specific cutoff values of lipid profiles may provide a clinical reference for screening or diagnosing CKD risk.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To investigate the population characteristics,distribution of traditional Chinese medicine(TCM)syndromes and influencing factors of long-term prognosis of diarrhea-predominant irritable bowel syndrome(IBS-D),and to provide evidence for the formulation of intervention program for IBS-D patients.Methods A total of 124 patients with IBS-D admitted to the medical institutions of the project team members from July 2020 to August 2022 were selected.According to the scoring results of IBS Quality of Life Measure(IBS-QOL),the patients were divided into the good prognosis group(81 cases)and the poor prognosis group(43 cases).The distribution of TCM syndromes in patients with IBS-D was explored,and the difference of IBS-QOL scores of the patients between good prognosis group and poor prognosis group was compared.Univariate logistic regression analysis and multivariate logistic regression analysis were used to determine the main risk factors for poor prognosis in patients with IBS-D.Results(1)The analysis of population characteristics showed that there was no significant difference in the proportion of male and female patients with IBS-D.The patients with IBS-D were usually middle-aged,and had a large interval span of the course of disease.The severity of their symptoms was mostly moderate.All of the patients with IBS-D had various degrees of anxiety and depression,and had nutritional imbalance.(2)The distribution of TCM syndromes in the patients with IBS-D were shown as the following:78 cases were identified as liver depression and spleen deficiency type,accounting for 62.90％;26 cases were identified as spleen-qi deficiency type,accounting for 20.97％;20 cases were identified as spleen and kidney yang deficiency type,accounting for 16.13％.(3)Analysis of IBS-QOL score showed that compared with the good prognosis group,the items scores of negative emotion,physical function,behavioral disorder,health status,being fastidious about food,social function,sexual behavior and interpersonal relationship of IBS-QOL in the poor prognosis group were significantly lowered(P＜0.01).(4)The univariate analysis showed that the risk of poor prognosis in patients with IBS-D would be increased by the factors of age,education level,course of disease,severity of symptoms,anxiety state,depression state,TCM syndrome types,Acute Physiology and Chronic Health Evaluation scoring system Ⅱ(APACHE 11)score,complication of neurological diseases,hemoglobin level,albumin level and total protein level(P＜0.01).(5)The multivariate Logistic regression analysis showed that the risk factors for poor prognosis of IBS-D patients involved age,education level below junior high school,the severity of symptoms being severe,Self-Rating Anxiety Scale(SAS)score,Self-Rating Depression Scale(SDS)score,TCM syndrome being liver depression and spleen deficiency type,hemoglobin level,albumin level and total protein level(P＜0.01).Conclusion Most of IBS-D patients exert long-term poor prognosis,and their long-term prognosis is affected by the factors of age,education level,severity of symptoms,anxiety and depression state,nutritional imbalance and TCM syndrome being liver depression and spleen deficiency type.The identification of the risk factors of poor prognosis will provide evidence for the formulation and adjustment of clinical intervention programs.

Objective To evaluate the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP)-based comprehensive minimally invasive treatment for biliary anastomotic stenosis (BAS) after liver transplantation. Methods Clinical data of 60 BAS recipients after liver transplantation were retrospectively analyzed, 54 male and 6 female, aged (48±10) years. ERCP was initially carried out. If it succeeded, plastic or metallic stents were placed into the biliary tract. If it failed, percutaneous transhepatic cholangial drainage (PTCD) or single-operator cholangioscopy (SpyGlass) was adopted to pass through the stenosis. If all these procedures failed, magnetic anastomosis or other special methods were delivered. The incidence and treatment of BAS after liver transplantation were summarized. The efficacy, stent removal and recurrence were observed. Results The median time of incidence of BAS after liver transplantation was 8 (4, 13) months. Within postoperative 1 year, 1-2 years and over 2 years, 39, 16 and 5 recipients were diagnosed with BAS, respectively. All 60 BAS recipients after liver transplantation were successfully treated, including 56 cases initially receiving ERCP, and 41 completing BAS treatment, with a success rate of 73%. The failure of guide wire was the main cause of ERCP failure. The success rates of PTCD, SpyGlass and magnetic anastomosis were 5/9, 5/7 and 7/8, respectively. Two recipients were successfully treated by percutaneous choledochoscope-assisted blunt guide wire technique and stent placement in the biliary and duodenal fistula. After 3 (3, 4) cycles of ERCP and 13 (8, 18) months of stent indwelling, 38 recipients reached the stent removal criteria, including 25 plastic stents and 13 metallic stents. The indwelling time of plastic stents was longer than that of metallic stents (P < 0.05). Six cases suffered from stenosis recurrence at 12 (8, 33) months after stent removal, and the recurrence rate was 16%. Six patients were treated with ERCP, and 5 of them did not recur after the stents were successfully removed. Multivariate analysis showed that delayed diagnosis of stenosis and frequent ERCP before stent removal were the independent risk factors for BAS recurrence (both P < 0.05). Conclusions ERCP-based comprehensive minimally invasive treatment may improve the success rate of BAS treatment after liver transplantation and yield satisfactory long-term efficacy. Delayed diagnosis of BAS and high frequent ERCP required for stent removal are the independent risk factors for BAS recurrence.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective:To discuss the type, treatment and results of different therapies of biliary fistula after orthotopic liver tansplantation(OLT).Methods:Data of 24 patients who developed biliary fistula after OLT in the First Affiliated Hospital of Xi′an Jiaotong University from January 2000 to March 2019 were retrospectively analyzed. Patients with biliary fistula were classified into 4 types according to presence or absence of stricture. All patients were treated by endoscopic retrograde cholangiopancreatography (ERCP) or interventional therapy, including endoscopic nasobiliary drainage (ENBD), endoscopic retrograde biliary drainage (ERBD) or percuteneous transhepatic cholangial drainage (PTCD). Main outcome measurements were the onset time of biliary fistula, the site of biliary fistula, the complications of ERCP or PTCD, the time of removing abdominal or biliary drainage tube, and the onset of new biliary stricture.Results:Biliary fistula was found in (46.5±36.6) days (6-122 days) after OLT. The numbers of patients in four types of biliary fistula were 6, 14, 2 and 2, respectively. Biliary fistula was cured in 22 patients, with clinical cure rate of 91.7%. All patients underwent ERCP first, and the technical success rate and clinical cure rate were 87.5% (21/24) and 85.7% (18/21), respectively. The clinical cure rates of ERCP forⅠ-Ⅳ biliary fistula were 6/6, 84.6%(11/13), 1/2, and 0, respectively. The clinical cure rates of ENBD and ERBD were 8/10 and 6/8, respectively. Five cases in whom ERCP failed, underwent PTCD, with technical success and clinical cure rates of 4/5 and 3/4 respectively. Eight patients(33.3%)developed cholangitis after treatment, and the incidence rate seemed higher in type Ⅱ biliary fistula than that in type Ⅰ [35.7% (5/14) VS 16.7% (1/6)]. Incidence of cholangitis was higher in patients with non-anastomotic stricture than those with anastomotic stricture [83.3%(5/6) VS 16.7%(3/18)].Conclusion:The first line treatment for biliary fistula after OLT is ERCP, followed by PTCD. The best procedures of biliary fistula typeⅠ-Ⅳ were ENBD, ENBD combined with ERBD, ENBD and PTCD, respectively.

Objective: To investigate the molecular mechanism of high phosphorylation levels of cofilin-1 (p-CFL-1) associated with paclitaxel resistance in epithelial ovarian cancer (EOC) cells. Methods: Cells displaying varying levels of p-CFL-1 and CFL-1 were created by plasmid transfection and shRNA interference. Cell inhibition rate indicating paclitaxel efficacy was assessed by Cell Counting Kit-8 (CCK-8) assay. Apoptosis was assessed by flow cytometry and protein levels were detected by western blotting. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to measure the expression levels of phosphokinases and phosphatases of CFL-1. Survival analysis evaluated the correlation between the prognosis of EOC patients and the levels of p-CFL-1 and slingshot-1 (SSH-1). Results: High levels of p-CFL-1 were observed in EOC cells that survived treatment with high doses of paclitaxel. SKOV3 cell mutants with upregulated p-CFL-1 showed impaired paclitaxel efficacy, as well as decreased apoptosis rates and pro-survival patterns of apoptosis-specific protein expression. Cytoplasmic accumulation of p-CFL-1 inhibited paclitaxel-induced mitochondrial apoptosis. SSH-1 silencing mediated CFL-1 phosphorylation in paclitaxel-resistant SKOV3 cells. Clinically, the high level of p-CFL-1 and the low level of SSH-1 in EOC tissues were closely related to chemotherapy resistance and poor prognosis in EOC patients. Conclusion The SSH-1/p-CFL-1 signaling pathway mediates paclitaxel resistance by apoptosis inhibition in EOC and is expected to be a potential prognostic predictor.
