Objective:To analyze the clinical characteristics of patients with spontaneous splenorenal shunt (SSRS) in liver cirrhosis, and to compare the effects and prognosis of different treatments.Methods:The data of cirrhotic patients with SSRS at the First Affiliated Hospital of Zhengzhou University between 2016-2022 were retrospectively analyzed.Patients were divided into Group A receiving conservative treatment, Group B by simple embolization, Group C undergoing TIPS combined with embolization, and Group D given liver transplantation. Life status, liver function changes, incidences of adverse events, and survival between groups were compared.Results:SSRS diameter was positively correlated with blood ammonia ( R=0.478) and negatively correlated with portal vein diameter ( R=-0.301). SSRS diameter is a protective factor for gastrointestinal hemorrhage and ascites and a risk factor for hepatic encephalopathy; Blood ammonia decreased and prothrombin time prolonged after treatment in group A ( P<0.05), blood ammonia decreased and albumin increased in group B ( P<0.05). Hemoglobin and bilirubin increased in group C ( P<0.05), blood ammonia and bilirubin decreased and platelets and albumin increased in group D ( P<0.05); Survival analysis showed that the prognosis of groups A and C was related to liver function, and the survival rate of group D was the highest of all ( P<0.05). Conclusions:SSRS embolization is safe and effective, and liver transplantation improves patient survival. Individualized treatment should be selected based on patient symptoms, liver function, and shunt diameter.

Objective To systematically evaluate the efficacy and safety of ciprofol for sedation and anesthesia outside the operating room.Methods Databases such as PubMed,Embase,Cochrane Library,Web of Science,CNKI,Wanfang Data,CBM,and VIP were searched for randomized controlled trials(RCTs)related to the efficacy and safety of ciprofol for sedation and anesthesia outside the operating room.The search covered all publications up to June 2023.Statistical analysis was performed using RevMan 5.4 software and Stata 15.0.Results Twelve RCTs were included,involving 2 192 patients,of which 1 154 were in the ciprofol group and 1 038 in the propofol group.Compared with the propofol group,the anesthesia induction time(MD=0.28 min,95％CI 0.08-0.47 min,P=0.006)and recovery time(MD=1.16 min,95％CI 0.44-1.87 min,P=0.001)were significantly longer in the ciprofol group,and the inci-dences of injection pain(OR=0.04,95％CI 0.02-0.06,P＜0.001),hypotension(OR=0.64,95％CI 0.49-0.83,P=0.0008),hypoxemia(OR=0.44,95％CI 0.21-0.91,P=0.03),and respirato-ry depression(OR=0.19,95％CI 0.11-0.32,P＜0.001)were significantly lower.There were no sta-tistically significant differences between the two groups in terms of sedation success rate,physician satisfac-tion,the difference in heart rate before and after anesthesia induction,incidence of body movement,brady-cardia,nausea and vomiting,and dizziness.Conclusion The anesthetic effect of cyclopofol and propofol is similar when used for anesthesia outside the operating room.Compared to propofol,ciprofol offers comparable anesthetic effects for sedation and anesthesia outside the operating room,with a lesser impact on respiratory function and more stable hemodynamics.Ciprofol also significantly lowers the incidence of adverse reactions such as injection pain,hypotension,hypoxemia,and respiratory depression.

Objective:To evaluate the testing capacity of HIV-1 viral load testing laboratories, and to provide data references for further improving the accuracy of laboratory test result in China.Methods:The test result of 155 positive samples distributed by the National AIDS Reference Laboratory to each laboratory from 2005 to 2019 were summarized and grouped according to the test assay and sample number. The independent sample t-test was used to evaluate the economic status and the proficiency testing (PT) assessment period on the stability of the test results. And, one-way analysis of variance was used to evaluate the influence of the types of laboratories and reagents on the stability of test results.Results:The number of HIV-1 viral load testing laboratories increased from 13 in 2005 to 267 in 2019. The participating institutions were mainly centers for disease control and prevention(CDC)and hospitals. Since 2015, the excellent rate of laboratories has remained above 85%, and the unqualified rate has remained below 3%. The associated factor analysis showed that the laboratory testing stability of HIV-1 viral load associated with the PT assessment period and the types of testing reagents, and the laboratories participating in the PT assessment for more than 5 years showed better stability.Conclusions:Participating in the annual proficiency testing program helped improve the laboratory capability of HIV-1 viral load testing in China.

Objective:To investigate the prognostic factors associated with unresectable (stage Ⅲa-Ⅳ, according to the 7th edition of the AJCC cancer staging manual) lung squamous cell carcinoma.Methods:We retrospectively analyzed 350 patients with inoperable locally advanced, recurrent or metastatic lung squamous cell carcinoma who were admitted to the First Affiliated Hospital of Chinese Medical University from January 2005 to June 2018. The clinical pathological data, treatment and survival follow-up information of the patients were collected. Kaplan-Meier survival was used to compare the overall survival rate of different risk groups. Univariate analysis and multivariate Cox regression analysis were used to determine the independent prognostic factors.Results:A total of 350 patients were enrolled. The median overall survival (OS) of these patients was 16.7 months.

Objective To examine the role of β-tubulin on the interaction between the cholecystokinin B receptor (CCKBR),dopamine D5 receptor(D5R), and water-sodium metabolism. Methods Normotensive and hypertensive renal proximal tubular cells(RPTC)were equally randomized into three separate groups: a gastrin group, fenoldopam group,and gastrin+nocodazole group. Immunofluorescence was used to determine localization of β-tubulin,CCKBR,and D5R. Western blotting was used to detect CCKBR, D5R, and Na-K-ATP expression. Results Gastrin stimulation in normotensive RPTC increased D5R expression(P < 0.05)and decreased Na-K-ATP expression(P < 0.05). These changes were blocked by a tubulin inhibitor(P < 0.05). However, interaction between CCKBR, D5R, and Na-K-ATP expression was not significantly affected in hypertensive RPTC. Immunofluorescence showed that CCKBR and D5R can induce one another,followed by transport to the plasma membrane, which can prevented by a tubulin inhibitor. Further, tubulin is disordered in hypertensive RPTC,which cannot support intracellular CCKBR and D5R transport. Conclusions tubulin plays a key role in the interaction between CCKBR, D5R, and water-sodium metabolism by improving protein transfer from the cytoplasm to cell membrane.

Objective To explore the role of Sestrin2 in pulmonary alveolar type II epithelial cell injury induced by cigarette smoking and its mechanism of action. Methods The cell injury model was induced by cigarette smoke extract (CSE)in the human pulmonary alveolar type II epithelial A549 cells. The generation of ROS was detected by DCFDA fluorescence probe. The levels of inflammatory factors TNF-α and IL-8 were determined by ELISA, and the expression of Sestrin2 and the peroxiredoxin,Prx-SO2/3H,was detected by Western blot. In addition,all the events were also measured in the A549 cells which were transfected with Sestrin2 siRNA and treated with azithromycin. Results After the CSE treatment,the expression of Sestrin2 in the A549 cells was decreased, the expression of Prx-SO2/3H was increased, the ROS production,secretion of cytokines TNF-α and IL-8 were increased(P < 0.05). These changes were partly reducedby azithromycin, indicating that azithromycin significantly relieved CSE-induced oxidative stress and inflammatory injury.Silencing of Sestrin2 in the A549 cells result ed in an increase of Prx-SO2/3 H expression, ROS production and the secretionof the cytokines TNF-α and IL-8. However, oxidative stress and inflammatory injury were not alleviated with the addition ofazithromycin in the Sestrin2 siRNA silencing A549 cells. Conclusions Sestrin2 plays an protective role in the pulmonaryalveolar type II epithelial cell injury induced by cigarette smoking through negatively regulating the level of intracellularROS via catalyzing the reduction of the hyperoxidized peroxiredoxin Prx-SO2/3 H.

PURPOSE: Endothelial progenitor cells (EPCs) play a key role in tissue repair and regeneration. Previous studies have shown that infusion of human umbilical cord blood-derived endothelial colony-forming cells improves outcomes in mice subjected to experimental traumatic brain injury (TBI). However, the efficiency of cell transplantation is not satisfactory. Oxidative stress plays a significant role in the survival of transplanted cells following ischemic reperfusion injury. This observational clinical study investigated the correlation between the number of circulating EPCs and plasma levels of superoxide dismutase (SOD) and malonyldialdehyde (MDA). MATERIALS AND METHODS: Peripheral blood samples were collected from 20 patients with mild TBI at day-1, day-2, day-3, day-4, and day-7 post TBI. The number of circulating EPCs and the plasma levels of SOD and MDA were measured. RESULTS: The average of circulating EPCs in TBI patients decreased initially, but increased thereafter, compared with healthy controls. Plasma levels of SOD in TBI patients were significantly lower than those in healthy controls at day-4 post-TBI. MDA levels showed no difference between the two groups. Furthermore, when assessed on day-7 post-TBI, the circulating EPC number were correlated with the plasma levels of SOD and MDA. CONCLUSION: These results suggest that the number of circulating EPCs is weakly to moderately correlated with plasma levels of SOD and MDA at day-7 post-TBI, which may offer a novel antioxidant strategy for EPCs transplantation after TBI.

Objective Little is known about the effects of antioxidant on the micturition function in diabetic cystopathy .In this study, we investigated the effects of antioxidant sulforaphane on bladder micturition function in diabetes mellitus ( DM)mice with bladder underactivity . Met hods We established DM models in mice by intraperitoneal injection of a single dose of streptozotocin (STZ)at 65 mg/kg and randomly divided them into three groups , sulforaphane treatment (n=10), vehicle treatment (n=10), and DM model (n=10), with another 10 normal healthy mice included as blank controls.At 24 weeks of the experiment, we obtained and analyzed such indexes of mice as the body weight , fasting blood glucose (FBG), 24-hour urine volume (24 h UV) and bladder wet weight ( BWW ) , results of cystometrography , and cystometric parameters including intercontraction interval ( ICI ) , maximum bladder pressure during micturition ( Pmax ) , maximum cystometric capacity (MCC), void volume (VV), post-void residual urine vol-ume (PVR) and residual urine rate (RUR). Results Compared with the blank controls , the DM models with bladder underactivity showed significantly increases in BWW ([67.96 ±2.35]mg), 24 h HU ([22.47 ±1.93]mL), MCC ([0.70 ±0.03]mL), VV (0[.23 ±0.01]mL), PVR ([0.49 ±0.02]mL), RUR ([70.10 ± 0.80]%), and ICI, but a remarkable decrease in Pmax .Sulforaphane treatment significantly reduced BWW ([576.9 ±2.41]mg), 24 h HU ([16.27 ±1.51] mL), MCC ([0.54 ±0.03]mL), PVR ([0.34 ±0.02]mL), RUR ([62.71 ±1.26]%), and ICI of the diabetic mice . Conclusion Sulforaphane could improve bladder micturition function in mice with STZ-induced DM , which might be related to its action mechanism of antioxidative stress damage .
