OBJECTIVETo assess the safety and clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with various stents for treating patients with cirrhosis and esophageal gastric varices bleeding.
METHODSOne hundred and five patients were stratified according to stent type: bare stent group, covered stent-grafts group, combined stents group. Rates of success, shunt insufficiency, rebleeding, patient survival, and major complications were observed. The shunt insufficiency rate, rebleeding rate, and survival rate were calculated by the life tables method, the Kaplan-Meier analytical curve, and the log-rank test; a p-value less than 0.05 was considered statistically significant.
RESULTSThe overall success rate of all TIPS for treating the esophageal gastric varices bleeding was 100%. The overall shunt insufficiency rates at 6-, 12-and 24-months post-TIPS were 8%, 9% and 16%, rebleeding rates were 2%, 6% and 17%, and survival rates were 100%, 97% and 94%. The shunt insufficiency rate was 26% in the bare stent group, 14% in the covered stent-grafis group, and 5% in the combined stents group (x2=1.00, P=0.61). The rebleeding rate was 33% in the bare stent group, 7% in the covered stent-grafts group, and 3%in the combined stents group (x2=1.69, P=0.43). The survival rate was 92% in the bare stent group, 93% in the covered stent-grafts group, and 100% in the combined stents group (x2=1.91, P=0.39). The shunt insufficiency rates were higher in patients with splenectomy than in those without splenectomy (30% vs.14%; x2=4.15, P=0.04). The intraperitoneal hemorrhage rates in the covered stent-grafis group and the combined stents group were significantly lower than that in the bare stent group (0% vs 0% vs 13%; x2=8.88, P=0.01).
CONCLUSIONSTIPS with an 8 mm stent effectively treated and prevented esophageal gastric varices bleeding in patients with cirrhosis. Intraperitoneal hemorrhaging caused by TIPS was significantly decreased in the covered stent-grafts group and combined stents group,which represented an improvement in safety of this treatment. However, the influence of covered stent-grafis and combined stents towards the clinical efficacy of TIPS needs further study.

Objective:To revise the 2017 classification of irreducible intertrochanteric fractures and summarize reduction techniques of 2021 classification.Methods:A retrospective analysis was conducted of the 17 patients with irreducible intertrochanteric fracture who had been treated at Department of Orthopaedic Surgery, The Ninth People's Hospital of Shanghai, Shanghai Jiaotong University School of Medicine from January 2015 to December 2019. They were 7 males and 10 females, with an age of (73.2 ± 16.1) years. On the basis of 2017 classification, the irreducible intertrochanteric fractures were classified into 2 types in the present 2021 classification. Type Ⅰ were interlocking fractures which were further classified into 3 subtypes: type ⅠA were sagittal interlocking ones (7 cases), type ⅠB greater trochanter interlocking ones (one case) and type ⅠC lesser trochanter interlocking ones (one case). Type Ⅱ were separating fractures which were further classified into 4 subtypes: type ⅡA were sagittal separating ones (4 cases), type ⅡB coronal separating ones (one case), type ⅡC rotational separating ones(one case) and type ⅡD complete separating ones (2 cases). All patients were treated by closed reduction and intramedullary nailing with different reduction strategies corresponding to their fracture types (application of ejector rods, clamps or prying techniques, etc.). A total of 132 patients with reducible femoral intertrochanteric fracture who had been admitted during the same period were selected as the control group. The fracture reduction time, intraoperative blood loss and Harris hip score at the last follow-up were compared between the 2 groups.Results:The 2 groups were comparable because there was no significant difference in their preoperative general data ( P>0.05). Type ⅠA accounted for the highest proportion of irreducible intertrochanteric fractures [41.3% (7/17)], followed by type ⅡA [23.6% (4/17)]. The fracture reduction time [(44.6 ± 6.7) min] in the irreducible group was significantly longer than that in the control group [(39.2 ± 9.6) min] ( P<0.05). There was no significant difference in intraoperative blood loss or Harris hip score at the last follow-up between the 2 groups ( P>0.05). Conclusions:Compared with the "2017 classification" , the "2021 classification" is more concise and easy to remember, and can directly prompt the corresponding proper fracture reduction techniques. The patients with irreducible intertrochanteric fracture using proper reduction techniques can obtain functional recovery similar to that in the patients with reducible intertrochanteric fracture after reduction and fixation.

【Objective】 To detect autoantibodies in Chinese systemic sclerosis (SSc) patients and analyze the relationship between clinical phenotype and autoantibodies in SSc. 【Methods】 We sequentially included 93 SSc patients. Their general information and clinical data were gathered. The differences in clinical characteristics among autoantibody negative and positive groups were analyzed statistically. 【Results】 Anti-nuclear antibodies were detected in 82 (88.2%) SSc patients. The positive rate of autoantibodies was detected in 26 cases (28.0%) of anti-Scl-70 antibody, 24 cases (25.8%) of anti-SSA/Ro-52 antibody, 19 cases (20.4%) of anti-U1-snRNP antibody, and 16 cases (17.2%) in anti-CENP-B antibody, respectively. The patients with positive anti-SSA/Ro-52 antibody had a significantly higher morbidity rate of pulmonary arterial hypertension (P=0.016). Patients with anti-Scl-70 antibody showed a higher incidence rate of digital tip ulcers or gangrene (P=0.004) and cardiac damage (P=0.014). The patients with anti-U1-snRNP antibody had a higher prevalence of pulmonary arterial hypertension (P=0.047) and Raynaud’s phenomenon (P=0.019), and showed an increased trend in the occurrence of interstitial lung disease (P=0.058). Those with anti-CENP-B antibody had a lower IgG level (P=0.049) and higher ALP (P=0.010) and γ-GT (P=0.003). The incidence of autoimmune liver disease was increased in anti-CENP-B positive patients (P=0.001). 【Conclusion】 Different autoantibodies in SSc are associated with clinical phenotype, and may contribute to the diagnosis, evaluation, and prognostic judgment of the disease.
