Objective To systematically evaluate the effect of exercise interventions on respiratory function,cough ability and swal-lowing function in patients with Parkinson's disease,and to compare the efficacy of different types of exercise in-terventions.Methods After constructing a PICO framework,randomized controlled trials(RCT)investigating the effects of exercise on respiratory function in Parkinson's disease were retrieved from Web of Science,PubMed,Cochrane Library,Embase,CNKI,Wanfang Data,VIP and CBM databases from the establishment of the databases to July 25th,2025.The risk of bias was assessed using the Cochrane Risk of Bias tool 5.1.0 and PEDro scale.RevMan 5.3 was used to create risk of bias graphs,and Stata 17.0 was used for meta-analysis.Results A total of eleven RCT involving 471 patients were included,with PEDro scale score of five to eight.Exercise in-terventions significantly improved forced vital capacity(FVC)(MD=0.42,95%CI 0.27 to 0.58,P<0.001),forced expiratory volume in first second(MD=0.32,95%CI 0.24 to 0.39,P<0.001),slow vital capacity(MD=0.80,95%CI 0.68 to 0.93,P<0.001),maximal inspiratory pressure(MD=11.53,95%CI 7.45 to 15.60,P<0.001),maximal expiratory pressure(MEP)(MD=16.75,95%CI 11.90 to 21.60,P<0.001),and peak expiratory flow(MD=55.77,95%CI 49.87 to 61.66,P<0.001)in patients with Parkinson's disease.Respiratory muscle training(RMT)significantly improved reflex peak cough flow(MD=3.51,95%CI 2.40 to 4.61,P<0.001)and voluntary peak cough flow(MD=3.09,95%CI 2.12 to 4.06,P<0.001).Subgroup analysis revealed that RMT was superior to non-ventilatory specific exercise(NVS)in improving MEP(P<0.05),whereas NVS was superi-or to RMT in improving FVC(P<0.05).Conclusion Exercise interventions can effectively improve respiratory function in patients with Parkinson's disease.NVS shows better efficacy in improving pulmonary function,while RMT can enhance cough ability,with more significant effect on respiratory muscle strength.

Objective To investigate the effectiveness and technical points of anatomical liver resection by trans-Glisson Sheath methylene blue staining in treatment of hepatolithiasis of right posterior lobe.Methods The clinical data of 12 cases of hepatolithiasis of right posterior lobe treated with anatomical liver resection by Glisson sheath methylene blue staining were retrospectively analyzed.Result 6 of 12 patients had undergone more than 2 previous biliary surgeries.All patients underwent contrast-enhanced CT scan and portography,hepatolithiasis of segment Ⅵ in 4 cases,right posterior lobe in 8 cases,accompanied by left lateral lobe bile duct stones in 2 cases,the right caudate lobe bile duct stones in 1 case.Methylene blue was injected into the portal vein,the methylene blue interface of segment Ⅵ or right posterior lobe displays well.Methylene blue interface was larger than the ischemia interface,which is in accordance with the anatomy.Along the methylene blue interface,hepatic resection was performed including right posterior lobe resection (n =9),segment Ⅵ resection (n =3),and combined with left lateral lobe resection (n =2) and the right caudate lobe resection (n =1).There was no postoperative mortality.Incision infection occurred in 5 cases,4 had right pleural effusion and 2 had a biliary fistula that were treated conservatively.With a mean follow-up period of 3.2 years,all patients are symptoms free and stone free.Conclusions Anatomical liver resection by methylene blue staining is a safe and effective treatment for hepatolithiasis of right posterior lobe.

Objective To investigate kupffer cells (KCs) expressing indoleamine 2,3-dioxygenase(IDO)in the inhibition of allogeneic T-cell proliferation in vitro. Methods Real-time PCR was used to investigate the expression of IDO mRNA and FasL mRNA in KCs pretreated with or without IFNγ. High performance liquid chromatography was used to analyze the catabolism of tryptophan by IDO from KCs. Allogeneic T-cell response was used to confirm the inhibition of KCs in vitro. The proliferation of lymphocytes was detected using [3 H] thymidine incorporation. Cell cycle and lymphocyte apoptosis were evaluated by flow cytometric assay. Results Real-time PCR revealed IDO mRNA and FasL mRNA expression in KCs pretreated with IFN-γ. IDO catabolic effect was confirmed by a decrease in tryptophan and increase in kynurenine concentration. KCs expressing IDO and FasL from BABL/c mice acquire the ability to suppress the proliferation of T-cells from C57BL/6, which could be blocked by the addition of 1-methyl-tryptophan and anti-FasL antibody. The co-cultured T-cells with KCs expressing IDO and FasL could induce allogeneic T-cell apoptosis and exhibited cell-cycle arrest in G1. Conclusion In addition to the Fas/FasL pathway, IDO may also play an important role in KCs to inhibit allogeneic T-cell proliferation in vitro.
