This systematic review was aimed to evaluation the effectiveness and safety of supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. Dtabases both at home and abroad were electronically searched for randomized controlled trials (RCTs) on supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. And meta-analyses were performed using RevMan 5.0 software. The results showed that 27 studies were included, which contained 2 908 cases. There were 1 490 cases in the treatment group, and 1 418 cases in the control group. The results of meta-analyses indicated that supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had significant differences in the effective rate for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (OR = 5.39, 95%CI (4.03, 7.22),P < 0.000 01). The treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on neurological function defects for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (WMD = -2.99, 95%CI (-3.26, -2.72),P < 0.000 01). In addition, the treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on improving the activity of daily living (WMD = 9.65, 95%CI (8.36, 10.93),P < 0.000 01). Adverse reaction and event was mild in 2 included research reports. It was concluded that the treatment of supplementingqi and activating blood circulation prescription or it combined with routine treatment in modern medicine was quite effective in the treatment of cerebral ischemic stroke by the existed limited evidences. It can also improve the nerve dysfunction and the ability of daily living. Due to the limited quantity of the included studies and the evidence with limited strength, further high-quality RCTs were needed to verify the forementioned conclusion.

Background Stickler syndrome is a genetic connective tissue disorder that affects the ocular,skeletal,orofacial and auditory systems.To determine the gene mutation loci can offer a basis for genetic diagnosis and management of Stickler syndrome.Objective The aim of this study was to research the clinical characteristics of a pedigree with Stickler syndrome and identify the disease-causing gene mutation.Methods This study was approved by Ethic Committee of Peking Union Medical College Hospital.The clinical study and pedigree analysis were performed in one family with Stickler syndrome type Ⅰ (STL Ⅰ).Nine family members were examined with informed consent.The entire coding regions of COL2A1 gene with flanking intronic regions were amplified by PCR and directly sequenced.The detected sequence change was confirmed to be mutationloci by examining whether they existed in normal control individuals.Mutant proteins were predicted with online software.Results There were 4 generations and 11 members in this family,and 2 members died,including 1 patient.Three patients were found in 9living families.Inheritance of this family complicd with an autosomal dominant inheritance mode.All affected individuals showed the consistent phenotypes with STL Ⅰ,including high myopia,membranous vitreous anomaly and surface central flat,short nose,palatoschisis,etc.Mutation screening of COL2A1 gene revealed that the first base of intron 12 was deleted(IVS12+1G del).Nucleotide sequence analysis showed that this mutation led to the functional abnormal of this gene by forming termination cordon in advance.This mutation occurred in all affected individuals,however,no mutation was observed in any unaffected member or 100 normal unrelated individuals.Conclusions This study identifies a novel splice-site mutation(IVS12+ 1G del)in COL2A1 gene in a Chinese STL Ⅰ pedigree.This is the first report on a mutation in a Chinese STL Ⅰ family.

Objective The aim of this study was to analyze risk factors which may affect prognosis of patients with hepatits B virus (HBV)-related liver failure,and to construct a model for prognostic evaluation and further assess its predictive ability.Methods In this retrospective cohort study,569 hospitalized patients who were diagnosed with HBV-related liver failure from January 2007 to December 2010 were enrolled.All the patients were followed up and survival analysis was performed using the Kaplan-Meier method.Univariate and multivariate COX proportional hazards regression analyses were applied to variables such as age,sex,complications,biochemical markers,coagulation markers,and HBV DNA levels to construct a model for prognostic evaluation,and 79 independent cases of HBV-related liver failure were used to confirm the model's predictive ability.Accuracy of the constructed model and model for end-stage liver disease (MELD) was evaluated by receiver operating characteristic (ROC) curves.Results The median survival time for all the patients was 59 days.The survival rates at 1,3,6 months were 58.9％,46.2％ and 45.5％,respectively;and survival rates at 1 and 3 years were 44.9％ and 44.5％,respectively.Hepatic encephalopathy,pulmonary infection,upper gastrointestinal bleeding (UGIB),albumin (Alb),aspartate aminotransferase (AST),creatinine (Cr),international normalized ratio (INR) were determined to be independent risk factors (all P＜0.01) which may affect survival of patients with HBV related liver failure.Accordingly,the prognostic index (PI) of the constructed model for prognostic evaluation 4.98 × assignment of hepatic encephalopathy + 4.57 × assignment of pulmonary infection + 4.41 ×assignment of UGIB-9.69 ×lm[Alb (g/L)]+2.46 ×ln[AST (U/L)]+5.18×ln[Cr (mmol/L)]+3.35×ln (INR) 15.36.The area under receiver operating characteristic curve was 0.838 for the constructed model assessing 90-d survival of the patients,and was 0.751 for model for end-stage liver disease,with no significant difference between the two models (Z=1.085,P =0.278).Conclusions Prognosis of patients with HBV-related liver failure can be accurately predicted by the constructed prognostic assessment model,which is consisted of hepatic encephalopathy,pulmonary infection,UGIB,Alb,AST,Cr,and INR as independent risk factors,and is able to predict the 90 d survival.

Objective:To design an intra-abdominal pressure measuring device applied to children on peritoneal dialysis (PD), and evaluate the feasibility and safety of the application of the device.Methods:The device consisted of a three-way stopcock with extension tubing, a three-way stopcock, a manometer tube, and a "Y" system peritoneal dialysis bag. The intraperitoneal pressure of different fill volumes was measured when a child was supine and relaxed in a horizontal position. The subjects of the study were children who received PD at the Pediatric Hospital of Fudan University from May 2019 to February 2020 and had PD dialysis age of>1 month. The children's demographic and clinical information were collected. During the measurement, the child’s complaints of pain, bloating, vital signs, and catheter-related contamination were recorded. Additionally, the occurrence of dialysis-related infections and complications during the hospitalization and outcomes of PD after three months of the measurement were tracked. A scatter plot and Pearson correlation test were used to explore the correlation between fill volumes and the intraperitoneal pressure.Results:Nine PD children were included in our study. The age of the children was (8.4±4.7) years old. The body surface area is (0.84±0.29) m 2. The intraperitoneal pressure was (12.6±1.9) cmH 2O at the fill volume of 1 000 ml/m 2 and (13.8±1.9) cmH 2O at the fill volume of 1 200 ml/m 2. The measurement was smoothly and safely taken without any case of contamination and dialysis-related infections during the hospitalization. After three months of the measurement, one child was transferred to temporary hemodialysis due to the aggravation of the umbilical hernia. Conclusions:The intraperitoneal pressure measuring device is feasible and safe to perform among children with PD. It can achieve non-invasive and continuous measurement of intra-abdominal pressure, and has guiding significance for the dialysis prescription of children with PD.
