Objective To observe the clinical efficacy of Jin's triple-needle therapy combined with bilateral high-frequency repetitive transcranial magnetic stimulation in the treatment of post-stroke hemiplegia.Methods A total of 116 patients diagnosed with post-stroke hemiplegia and admitted to the wards and outpatient clinics of Yan'an City Hospital of Traditional Chinese Medicine from January 2023 to June 2024 were selected as the study subjects.The patients were randomly divided into an observation group and a control group using a random number table,with 58 patients in each group.The control group received bilateral high-frequency repetitive transcranial magnetic stimulation,while the observation group received Jin's triple-needle therapy in addition to the control group's treatment.After 30-day treatment,the clinical efficacy of the two groups was evaluated.Changes in traditional Chinese medicine(TCM)syndrome scores,Fugl-Meyer Assessment(FMA)scores for limb motor function,and Stroke-Specific Quality of Life(SS-QOL)scores were observed before and after treatment.Changes in neuron-specific enolase(NSE),glial fibrillary acidic protein(GFAP),and central nervous system-specific protein(S100-β)levels were compared between the two groups before and after treatment.The safety and incidence of adverse reactions in both groups were also evaluated.Results(1)The total effective rate in the observation group was 91.38%(53/58),compared to 75.86%(44/58)in the control group.The observation group showed significantly better efficacy than the control group,with a statistically significant difference(P＜0.05).(2)After treatment,both groups showed significant improvements in TCM syndrome scores and FMA scores for limb motor function(P＜0.05),and the observation group was significantly superior to the control group in improving TCM syndrome scores and FMA scores,with a statistically significant difference(P＜0.05).(3)After treatment,both groups showed significant improvementss(P＜0.05)in NSE,GFAP,and S100-β level,and the observation group was significantly superior to the control group in improving NSE,GFAP,and S100-β levels,with a statistically significant difference(P＜0.05).(4)After treatment,both groups showed significant improvements in SS-QOL scores for quality of life(P＜0.05),and the observation group was significantly superior to the control group in improving SS-QOL scores,with a statistically significant difference(P＜0.05).(5)The incidence of adverse reactions in the observation group was 12.07%(7/58),compared to 8.62%(5/58)in the control group.There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion Jin's triple-needle therapy combined with bilateral high-frequency repetitive transcranial magnetic stimulation can significantly improve clinical symptoms,enhance limb motor function,reduce levels of brain injury markers,and improve the quality of life in patients with post-stroke hemiplegia.The treatment is safe and shows significant efficacy.

BACKGROUND:Diabetic nephropathy is an important cause of end-stage renal disease,and intestinal barrier damage plays an important role in the occurrence and development of diabetic nephropathy. OBJECTIVE:To observe the protective effect of human umbilical cord mesenchymal stem cells on the intestinal barrier in rats with diabetic nephropathy. METHODS:Thirty 8-week-old male SD rats were randomly assigned to healthy control group,model group and human umbilical cord mesenchymal stem cell group,with 10 rats in each group.Rats in the human umbilical cord mesenchymal stem cell group were injected with 1×106 human umbilical cord mesenchymal stem cells through the tail vein once a week for 4 weeks after the model establishment of diabetic nephropathy.Rats in the healthy control group and the model group were injected with an equal volume of PBS at the same time.1 week after the last injection,the histomorphological changes in the kidney and colon were observed under a light microscope.The expressions of ZO-1 and Occludin in the colon tissue of rats were detected by immunohistochemistry.Serum D-lactic acid and lipopolysaccharide levels were detected by ELISA.In addition,the distribution of human umbilical cord mesenchymal stem cells labeled with DiR dye in rats was observed by in vivo imaging system.The expression of human mesenchymal stem cell surface marker antigens CD44 and CD90 in colon tissue was detected by immunohistochemistry. RESULTS AND CONCLUSION:(1)Compared with the model group,human umbilical cord mesenchymal stem cell transplantation significantly inhibited the increase of urea nitrogen,serum creatinine,24-hour urine protein level and urinary albumin/creatinine ratio in diabetic nephropathy rats(all P<0.05).(2)The expression of human mesenchymal stem cell surface markers CD44 and CD90 was found in the colon of diabetic nephropathy rats.(3)Compared with the healthy control group,the expression levels of tight junction proteins Occludin and ZO-1 in the colon tissue of the model group were significantly reduced,while the expressions of Occludin and ZO-1 were significantly increased after treatment with human umbilical cord mesenchymal stem cells.(4)Compared with the model group,human umbilical cord mesenchymal stem cell transplantation significantly reduced serum D-lactic acid and lipopolysaccharide levels in diabetic nephropathy rats.(5)The results suggest that human umbilical cord mesenchymal stem cells may protect the intestinal barrier function by enhancing the expression of intestinal tight junction proteins in diabetic nephropathy rats.

Objective:To explore the effect of out-of-hospital nursing based on gratitude extension-construction theory on self-management efficacy of young and middle-aged patients undergoing percutaneous coronary intervention (PCI) .Methods:A total of 136 young and middle-aged patients who underwent PCI in Coronary Heart Disease Ward of Department of Cardiology in Henan Provincial People's Hospital were selected as the research objects by the convenient sampling method. The patients were randomly divided into the control group and the observation group by the envelop method, with 68 patients in each group. The control group received routine out-of-hospital nursing, while the observation group received out-of-hospital nursing based on gratitude extension-construction theory. Self-management efficacy was compared before and after intervention between the two groups.Results:After intervention, the scores for self psychological management, self-management confidence, self-management behavior, self-management cognition and self-management information in the observation group were higher than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:Out-of-hospital nursing based on gratitude extension-construction theory can significantly improve self-management efficacy of young and middle-aged patients undergoing PCI.

Objective To explore the effect of intermittent hypoxia (IH) on RhoA/ROCK pathway in lung and on the muscularization in pulmonary vascular in rat model. Methods Wistar rats (n=40) were randomly divided into two groups:the normal oxygen control group (n=20) and the IH group ( n=20). For 4 weeks, rats in control group and IH group were ex?posed to intermittent normal oxygen (21%O2) or IH (5%-21%O2) respectively. Then, mRNA transcription and protein trans?lation levels of RhoA/ROCK were examined by Real-time PCR and Western blot. Expression of proliferation cell nuclear an?tigen (PCNA) andα-smooth muscle actin (SM-α-actin ) of lung and pulmonary artery were detected by immunohistochemis?try. Results RhoA mRNA transcription level(0.463 ± 0.067 vs 0.182 ± 0.040), ROCK mRNA transcription level(0.384 ± 0.062 vs 0.192 ± 0.052), RhoA protein expression level(0.827 ± 0.065 vs 0.424 ± 0.075)and ROCK protein expression level (0.488±0.088 vs 0.336±0.102)were higher in IH group than those in control group(P<0.05);Levels of PCNA in lung tissue [(54.67±1.80)%vs (9.14±0.91)%], PCNA in pulmonary artery [(49.40±1.21)%vs (8.38±1.13)%], SM-α-actin in lung tis?sue [(42.66±1.63)%vs (35.44±1.41)%] and SM-α-actin in pulmonary artery [(62.62±2.53)%vs (45.54±2.58)%] were also higher in IH group than those in control group(P<0.05). Conclusion Rho/ROCK pathway may play an important role in developing pulmonary hypertension (PH) associated with IH;and IH can promote the muscularization in pulmonary vascular to accelerate PH.

Objective To observe the early reperfusion therapy status for patients with ST elevation acute myocardial infarction (STEMI) hospitalized in tertiary and secondary hospitals in Henan province.Methods Baseline data, early reperfusion treatment and in-hospital mortality of STEMI patients hospitalized in 17 hospitals in Henan province (8 tertiary hospitals, 9 secondary hospitals) from June 2011 to June 2012 were obtained using a uniformed questionnaire.Results One thousand six hundred and eighty six patients were enrolled, of which 886 patients were hospitalized in tertiary hospitals and 880 patients were early hospitalized in secondary hospitals.Six hundred and fifty four patients (38.8％, 654/1 686) underwent early reperfusion therapy (543 with thrombolysis and 111 with primary percutaneous coronary intervention (PCI)).There was no difference in the proportion of early reperfusion therapy between tertiary and secondary hospitals (40.1％ (355/886) vs.37.4％ (299/800), P =0.257).The median time from symptom onset to first medical contact, door-to-needle and door-to-balloon was 132 min, 18 min and 60 min, respectively.The median time from symptom onset to first medical contact (150 min vs.120 min, P =0.001), door-to-needle (30 min vs.18 min, P =0.003) and symptom onset-to-thrombolysis (3.5 h vs.2.7 h, P =0.001) were significantly longer in tertiary hospitals than in secondary hospitals.No difference was found in median time of door-to-balloon, symptom onset-to-primary PCI or symptom onset-to-elected PCI between tertiary and secondary hospitals (all P ＞0.05).The proportion of door-to-needle≤30 min was lower in tertiary hospitals than in secondary hospitals (46.4％ (84/181) vs.62.2％ (153/246), P =0.001).However, there was no difference in the proportion of door-to-balloon ≤90 min between tertiary and secondary hospitals (58.8％ (60/102) vs.57.1％ (4/7), P =1.000).In-hospital mortality was also similar between tertiary and secondary hospitals (5.8％ (51/886) vs.5.5％ (44/800), P =0.820).Conclusions Early reperfusion rate is low, and thrombolysis is the main early reperfusion therapy in both tertiary and secondary hospitals in Henan province.Tertiary hospitals did not take advantage of their primary PCI capability.There is great room for improvement in early reperfusion therapy in tertiary and secondary hospitals.

Objective To affirm the expression of Toll like receptor 4 (TLR4) on the surface membrane of platelet and to explore the immunomodulatory factors[(interlukine-8(IL-8),β-thromboglobulin(β-TG), soluble CD40 ligand(sCD40L)] released by platelets after platelets stimulated by TLR4 ligand.Methods TLR4 expressed on the platelet was detected by flow cytometry. Monoclonal anti-human FcγRⅡantibody(Ⅳ.3)-treated human platelets were cultured with LPS in the presence or absence of blocking monoclonal antibody to human TLR4. The release of IL-8, β-TG, sCD40L were measured by specific enzymelinked immunosorbent assay. Results Human platelets could express functional TLR4. The detection rate of TLR4 on platelets were decreased after LPS involvement(P<0.01). It was noted that sCD40L and β-TG were present in large concentration in the release of platelets stimulated by TLR4 ligand but the release of IL-8 was independent of platelet activation after TLR4 engagement. The concentration of sCD40L and β-TG had no statistical difference between 1-5 μg/ml LPS. The effects of LPS on the modulation of secretory factors were attenuated by preincubation of platelets with an anti-TLR4 monoclonal antibody. Conclusion The TLR4 on platelet could recognize and link LPS, induce the release of sCD40L, β-TG by platelet, but could not influence IL-8.
