Objective To establish a rat model of venous thrombosis in a plateau hypobaric hypoxic environment and to investigate the effect of this environment on venous thrombosis.Methods A total of 144 healthy male SD rats were assigned randomly to four groups(n=36 rats per group):a plains sham operation(A)group,plains operation(B)group,plateau altitude 6000 m+sham operation(C)group,and plateau altitude 6000 m+surgery(D)group.Rats in A and B groups were maintained in a plains normoxic environment,while rats in C and D groups C and D were subjected to a plateau environment.Rats in the surgical groups underwent quantitative constriction to incompletely obstruct the inferior vena cava blood flow.Each group was further divided into subgroups based on time:1,3,5,7,14,and 21 d(n=6 rats per group).Regular vascular ultrasound monitoring was conducted,and blood samples were taken for whole blood viscosity testing and the assessment of inflammatory indicators,including endothelin-1(ET-1),interleukin-6(IL-6)and tissue factor(TF).Coagulation function was evaluated through the activated partial thromboplastin time(APTT),prothrombin time(PT),thrombin time(TT),fibrinogen(FIB)and D-dimer.After the observation period,the experimental animals were sacrificed and the limbs were removed.Thrombus samples were stained with hematoxylin/eosin(HE),and the thrombus wet mass was measured.Results The thrombosis incidence was significantly higher in the plateau D group than in B group,accompanied by a marked increase in blood viscosity and hematocrit(P<0.01).Additionally,levels of ET-1,IL-6,and TF were significantly elevated(P<0.05),indicating a coagulation disorder.Conclusions A plateau hypoxic environment model can be successfully simulated by quantitative coarctation of the inferior vena cava,combined with a specialized environmental chamber.The findings of this study suggest that a plateau hypoxic environment promotes venous thrombosis.

Cholangiocarcinoma is the most common malignant tumor of the biliary tract, with a relatively high mortality rate and an incidence rate increasing year by year. Due to atypical symptoms in the early stage and complex anatomical location, it is often difficult for patients with cholangiocarcinoma to be diagnosed in the early stage, and therefore, they often miss the optimal treatment period and tend to have poor prognosis. In recent years, studies have shown that miRNAs play a key role in the pathophysiological process of the development and progression of cholangiocarcinoma. This article reviews the regulatory role of miRNAs in the development, invasion, metastasis, drug resistance, and tumor microenvironment of cholangiocarcinoma and introduces the latest advances in exosome miRNA and cholangiocarcinoma, so as to provide potential treatment strategies for cholangiocarcinoma.

Objective To evaluate the effect of mild hypothermia on the expression of phosphorylated eukaryotic translation initiation factor 2α (p-eIf2αt) in the hippocampus in a mouse model of cerebral ischemia-reperfusion (I/R).Methods Sixty pathogen-free healthy male C57BL6 mice,aged 8-12 weeks,weighing 20-30 g,were divided into 3 groups (n =20 each) using a random number table:sham operation group (group S),group I/R and mild hypothermia group (group H).Cerebral I/R was induced by 15-min occlusion of bilateral common carotid arteries followed by reperfusion in chloral hydrate-anesthetized mice.Surface cooling was started immediately after reperfusion to maintain the rectal temperature at 32-34 ℃ for 3 h in group H.The neurologic deficit score was evaluated at 24 h of reperfusion.The mice were then sacrificed,brains were immediately removed,and hippocampi were isolated for examination of pathologic changes of hippocampal CA1 region and for determination of neuroapoptosis (by TUNEL) and expression of peIf2α (by Western blot).The apoptosis rate was calculated.Results Compared with group S,the neurologic deficit scores at 24 h of reperfusion and apoptosis rate of hippocampal neurons were significantly increased,and the expression of p-eIf2α was up-regulated in I/R and H groups (P<0.05).Compared with group I/R,the neurologic deficit scores at 24 h of reperfusion and apoptosis rate of hippocampal neurons were significantly decreased,and the expression of p-eIf2α was down-regulated in group H (P< 0.05).Conclusion Mild hypothermia reduces endoplasmic reticulum stress and inhibits neuroapoptosis through inhibiting the expression of p-eIf2α in the hippocampus in a mouse model of cerebral I/R.

Objective To investigate the continuous ambulatory peritoneal dialysis (CAPD) and daytime ambulatory peritoneal dialysis (DAPD) on sleep and quality of life. Methods In this is a multi-center cross-sectional survey, we used the Pittsburgh Sleep Index Scale (PSQI) and the Chinese version of peritoneal dialysis patient quality of life scale, the unified investigating time, the organized trained peritoneal dialysis nurses qualified to conduct research full-time. Survey content includes general information, sleep and quality of life, laboratory tests, dialysis adequacy and other indicators, and the results were pooled analysis. Results A total of 325 hospitalized peritoneal dialysis patients were included in the study, including 177 patients in CAPD, 148 patients in DAPD. The total scores of QOL, physical function, physical factors, psychological status, social function and life satisfaction were (72.61± 10.94), (19.44±3.65), (59.69±7.31), (32.65±5.65), (24.82±6.03), (15.42±5.47)and (74.06±13.59), (20.16± 2.95), (58.99 ± 5.86), (34.58 ± 6.17), (25.10 ± 5.01), (15.36 ± 4.28). The score of CAPD in the mental state dimension was significantly lower than that in DAPD patients (t=-3.715, P<0.01). Else, there was no significant difference between the two groups (P> 0.05). Conclusions Sleep and quality of life in peritoneal dialysis patients are lower than normal adults. Dialysis modes have an impact on sleep andquality of life of patients, health care workers should fully assess the physical and mental state of the patients in order to select the appropriate mode of dialysis.

Objective To determine the dose-response relationship of sufentanil blunting responses to double-lumen endotracheal intubation when combined with propofol given by target-controlled infusion (TCI) in patients with pulmonary tuberculosis.Methods One hundred patients of both sexes with pulmonary tuberculosis,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 24-58 yr,with body mass index <30 kg/m2,with Mallampati grade Ⅰ or Ⅱ,undergoing thoracic surgery under general anesthesia,were divided into Ⅰ-Ⅴ groups (n =20 each) using a random number table.Anesthesia was induced with iv sufentanil 0.35 μg/kg (group Ⅰ),0.40 μg/kg (group Ⅱ),0.45 μg/kg (group Ⅲ),0.50 μg/kg (group Ⅳ) and 0.55 μg/kg (group Ⅴ),and propofol TCI (target plasma concentration 3.5 μg/ml) and iv vecuronium 0.15 mg/kg.The patients were endotracheally intubated and mechanically ventilated.The response to double-lumen endotracheal intubation was defined as positive when mean arterial pressure increased by> 20% of the baseline value and/or heart rate > 90 bpm within 5 min after intubation.The median effective dose (ED50),ED95 and 95% confidence interval (95% CI) of sufentanil blunting the responses to double-lumen endotracheal intubation were calculated by Probit analysis.Results The ED50 (95% CI) and ED95 (95% CI) of sufentanil blunting the responses to intubation were 0.411 (0.370-0.441) μg/kg and 0.635 (0.556-0.888) μg/kg,respectively,when combined with propofol given by TCI.Conclusion When combined with propofol given by TCI (target plasma concentration 3.5 μg/ml),the ED50 and ED95 of sufentanil blunting the responses to double-lumen endotracheal intubation are 0.411 and 0.635 μg/kg,respectively,in patients with pulmonary tuberculosis.
