Objective To investigate the effect of leg cycle ergometer on walking ability of stroke patients with hemiplegia at convalescent period.Methods Seventy patients with hemiplegia after stroke for 3 to 6 months with a certain walking capability were randomly divided into the treatment group and control group with 35 cases in each group.The control group was treated with routine rehabilitation training;the treatment group was added with leg cycle ergometer training.All patients in the two groups were assessed with simplified Fugl-Meyer Assessment(FMA),Berg Balance Scale(BBS),ambulation capacity(walking time in 10 meters and walking distance in 6 minutes and Holden's functional ambulance classification),changes of spasticity,and the ability of daily living(ADL)at the time of begin and 6 weeks later.Results The motor function of lower extremity,balance performance,walking capability and ADL of the patients in two groups improved(P<0.05)after 6 weeks' treatment,but the therapeutic effect of the treatment group was better than the control group(P<0.05).Conclusion The application of leg cycle ergometer combined with routine rehabilitation training can distinctly improve the motor function of lower extremity,balance performance,walking ability and ADL for patients after stroke.

Objective:To systematically assess the effectiveness and safety of acupuncture for spastic hemiplegia after ischemic stroke. Methods:Randomized controlled trials(RCTs)of acupuncture treatment for spastic hemiplegia after ischemic stroke meeting the inclusion criteria in Cochrane Library,Medline,Excerpta Medica Database(EMBASE),PubMed,China National Knowledge Infrastructure(CNKI),SinoMed,Chongqing VIP Database(VIP),and Wanfang Data Knowledge Service Platform(Wanfang)published from each database's inception to February 2023 were retrieved by computer.Two reviewers independently extracted data and evaluated the risk of bias using Cochrane's risk of bias tool.Review Manager 5.4 was used for data analysis.Continuous data were evaluated using mean difference(MD)with a 95%confidence interval(CI),and dichotomous data were analyzed using risk ratio(RR). Results:A total of 24 trials,including 1 970 participants,were included in the study.The meta-analysis of 7 trials showed that compared to the rehabilitation therapy,acupuncture therapy was more effective in improving the simplified Fugl-Meyer assessment score after 1-month treatments[MD=10.52,95%CI(7.81,13.23),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.18,95%CI(11.34,27.02),P<0.001],and the 6-month treatment course resulted in better outcomes than the 1-month course.The meta-analysis of 8 trials showed that acupuncture had a better improvement on the Barthel index score than rehabilitation therapy after 1-month treatments[MD=10.78,95%CI(8.91,12.64),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.94,95%CI(19.02,20.87),P<0.001],and the 6-month course was better than the 1-month course.The meta-analysis of 2 trials showed that the effective rate of the modified Ashworth scale score improvement was more notable in the acupuncture group after 1-month treatments[RR=1.20,95%CI(1.02,1.40),P=0.020].One trial reported no adverse event,and 1 trial reported 3 adverse events without severe influence. Conclusion:Acupuncture might be an effective and safe therapy for spastic hemiplegia after ischemic stroke,but more high-quality,large-sample objectively-evaluated RCTs are needed to validate the conclusion.

Objective To evaluate the effect of transversus abdominis plane (TAP) block on postoperative cognitive function in elderly patients undergoing laparoscopic surgery under general anesthesia.Methods Forty-eight male patients undergoing laparoscopic tension-free repair of inguinal hernia under general anesthesia,aged 65-75 yr,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,with body mass index of 20-28 kg/m2,were divided into 2 groups (n =24 each) using a random number table method:TAP block combined with general anesthesia group (group TG) and general anesthesia group (group G).Anesthesia was induced with midazolam,cisatracurium besylate,sufentanil and etomidate,and the patients were mechanically ventilated after laryngeal mask airway insertion.TAP block was performed through the anterior superior iliac spine approach,and 0.25％ ropivacaine 30 ml was injected in group TG.Anesthesia was maintained by target-controlled infusion of propofol and remifentanil and muscle relaxation by intravenously injecting cisatracurium.The occurrence of cerebral regional oxygen saturation (rSO2) and low rSO2 events (rSO2 ＜60％) was recorded at 1 min before anesthesia induction (T0),5 min after inserting the laryngeal mask airway (T1),at skin incision (T2),30 min after skin incision (T3),and at the end of surgery (T4).The consumption of propofol and remifentanil was recorded during surgery.Montreal Cognitive Assessment (MoCA) was used to evaluate the cognitive function of patients at 1 day before surgery and 7 days after surgery,and the development of postoperative cognitive dysfunction (POCD,MoCA scores＜ 26) was recorded.Results Compared with group G,the intraoperative consumption of propofol and remifentanil was significantly reduced,rSO2 was increased at T2~,and the incidence of low rSO2 events was decreased,MoCA scores were increased at 7 days after surgery,and the incidence of POCD was decreased in group TG (P＜0.05).Conclusion TAP block can reduce the incidence of POCD in elderly patients undergoing laparoscopic surgery under general anesthesia.

Objective To evaluate the clinical efficacy and safety of different stitching methods,over-the-scope-clip (OTSC) and metal clips combined with nylon rope (King closure),for full-layer gastric wall defect.Methods Data of 75 cases,who underwent endoscopic full-thickness resection (EFTR) of gastric SMTs from May 2015 to May 2018 in our endoscopy center were retrospectively analyzed.According to the closure method,the patients were divided into the OTSC group (20 cases) and the King closure group (55 cases).Comparison was made in gender,age,the largest diameter of tumor,the location of tumor,defect surface diameter,total operating time,defect closure time,closure success rate,the length of hospital stays,cost and postoperative complications between the two groups,Results The baseline data were comparable,and there were no significant differences in age,gender,tumor location,tumor diameter,and defect surface diameter between the two groups(all P＞0.05).The success rate of closure was 100％ in both groups.In terms of length of hospital stay,there was no significant difference between the two groups (t =1.13,P=0.268).The total operating time was 63.24±43.22 min in the King closure group versus 47.60± 18.13 min in the OTSC group (t =2.20,P =0.030).The closure time of the defect surface was 20.85 ± 16.35 min in the King closure group versus 10.95±5.20 min in the OTSC group (t =2.65,P=O.010).Hospitalization costs were 24 200±800 yuan in the King closure group versus 36 200±2 350 yuan in the OTSC group (t=6.21,P＜0.001).Postoperative abdominal elevation radiographs in both groups indicated a small amount of subphrenic free gas,and no intervention was given due to the small amount of gas and no obvious symptoms.No late bleeding,recurrent perforation,infection or other complications occurred after operation,and all patients were discharged successfully.Six months after surgery,15 patients (27％) in the King closure group developed metal clips or nylon rope residue,which were successfully removed by endoscopy.The anastomosis clamp of nighteen patients (95％) in the OTSC group were in the original position.None of the patient received open surgery.Conclusion OTSC and King closure are both safe and effective in the treatment of full-thickness defect of gastric wall.OTSC has the advantages of short total operation time and short closure time,but with high cost.

Objective:To design a modified S1PR3 specific agonist, GPS-725.017, and investigate its protective effect on acute lung injury by promoting macrophage clearance of bacteria.Methods:A short peptide derived from the intracellular region of S1PR3 receptor was named GPS725.017, which was modified with norleucine (Nle) and myristicacid (myr) at its N terminus. Mice were divided into the sham operation group, solvent group and GPS-725.017 treatment group. The acute lung injury model was induced by endotracheal injection of E. coli (5×10 6 CFU), and the experimental group was treated with GPS-725.017 (10 mg/kg). The 48-h survival rate of mice was recorded. After 5 h of modeling, the bacterial load and inflammatory cytokines in peripheral blood and lung were detected, and Vps34 protein content in alveolar macrophages was determined by Western blot. After 12-h of modeling, lung tissues were collected for H&E staining and pathological scores. Results:Compared with the solvent group, the survival rate of mice in the GPS-725.017 treatment group was significantly improved ( P<0.01), the bacterial CFU in blood and alveolar lavage fluid was significantly lower than that in the solvent group ( P<0.001), and the levels of TNF-α and IL-1β in blood and alveolar lavage fluid were significantly lower than those in the solvent group ( P<0.001). Western blot showed that the expression level of Vps34 protein in alveolar macrophages was significantly higher than that in the solvent group ( P<0.01). Histopathology result showed that the pathological damage of lung in the treatment group was significantly less than that in the solvent group ( P<0.001). Conclusions:The modified synthetic S1PR3 specific agonist GPS-725.017 could specifically activate the S1PR3 receptor on the membrane of alveolar macrophages and up-regulate the expression level of intracellular Vps34 protein, which can promote the removal of bacteria in alveolar macrophages, significantly reduce the degree of lung injury and improve the survival rate in ALI mice.

Objective:To investigate the effects of different connection schemes of continuous renal replacement therapy (CRRT) and extracorporeal membrane oxygenation (ECMO) on arterial pressure (PA), venous pressure (PV), and transmembrane pressure (TMP), and to provide a theoretical basis for choosing a suitable connection scheme.Methods:① In vitro study: the different connection schemes of CRRT and ECMO were simulated and divided into 6 schemes according to the connection between CRRT and ECMO circuits at different positions. Scheme A: connected to the front and back points of the oxygenator; scheme B: connected to the points behind and in front of the oxygenator; scheme C: connected to the points in front of the oxygenator and in front of the centrifugal pump; scheme D: connected to the points behind the oxygenator and in front of the centrifugal pump; scheme E: connected to the points in front of the oxygenator and the return catheter; scheme F: connected to the points after the oxygenator and the return catheter. Each set of ECMO circuits was measured 5 times under each connection scheme and different flow rates (2, 3, 4, 5, 5.5 L/min). Six ECMO circuits for a total of 30 measurements, and the PA, PV, and TMP of the 6 schemes were compared. ② In vivo study: the patients who were treated with ECMO combined with CRRT in the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College from August 2017 to August 2021 changed the connection scheme due to high PA or PV (from scheme A or B to scheme E or F) were retrospectively analyzed. The changes of PA and PV before and after changing the scheme were compared. Results:① In vitro study results: there was no significant difference in PA between schemes A and B, C and D, E and F under different ECMO blood flow (2-5.5 L/min). The PA of schemes C and D was the lowest, followed by schemes E and F. PV of scheme B was higher than that of scheme A under different ECMO blood flow (2-5.5 L/min). There was no significant difference in PV between schemes C and D, E and F under high ECMO blood flow (3-5.5 L/min), and the absolute value of PV was lowest in schemes E and F. Compared with schemes A and B [partial PA > 300 mmHg (1 mmHg≈0.133 kPa) at high flow rate], C and D (partial PV > 350 mmHg at high flow rate), schemes E and F were more reasonable connection schemes. TMP was negative in schemes C and D at ECMO blood flow of 5 L/min and 5.5 L/min (mmHg; 5 L/min: scheme C was -29.14±11.42, scheme D was -42.45±15.70; 5.5 L/min: scheme C was -35.75±13.21, scheme D was -41.58±15.42), which indicated the presence of dialysate reverse filtration. Most of the differences in TMP among schemes A, B, E, and F under different ECMO blood flow (2-5.5 L/min) were statistically significant, and the absolute value of mean fluctuation was 9.89-49.55 mmHg, all within the normal range. ② In vivo study results: a total of 10 patients who changed the connection scheme (from scheme A or B to E or F) due to high PA or PV were enrolled, including 8 males and 2 females; 7 cases of venous-arterial ECMO (VA-ECMO) and 3 cases of venous-venous ECMO (VV-ECMO), all used continuous veno-venous hemodiafiltration (CVVHDF) mode. After changing the scheme, both PA and PV decreased significantly as compared with those before changing [PA (mmHg): 244.00±22.58 vs. 257.20±21.92, PV (mmHg): 257.20±18.43 vs. 326.40±15.41, both P < 0.01], and PV decreased more significantly than PA [difference (mmHg): 69.20±6.55 vs. 13.20±5.45, P < 0.01]. Conclusion:For patients treated with ECMO in combination with CRRT, the scheme of connecting the access line of CRRT to the pre-oxygenator or post-oxygenator and connecting the return line to the point of the return catheter can significantly reduce PA and PV and maintains normal CRRT operation even running high-flow ECMO.
