Background: Overactive bladder (OAB) is a prevalent condition that substantially degrades patient quality of life. Acupuncture is recognized as an effective therapeutic approach for various urological diseases. However, there is limited evidence validating the effectiveness and safety of acupuncture for OABs. Objective: To assess the therapeutic efficacy of acupuncture for OAB and to investigate the potential mechanisms by analyzing its effects on relevant urinary biomarkers. Methods: This is a randomized, participants and outcome assessors blinded, sham acupuncture controlled trial. A total of 110 patients with OABs will be randomly divided in a 1:1 ratio between the acupuncture and sham acupuncture groups. Participants in the acupuncture group will undergo 30-min authentic acupuncture, while their counterparts in the sham acupuncture group will undergo sham acupuncture needling non-acupoints superficially three times weekly for a duration of 8 weeks. The two co-primary outcomes will be the change in the mean number of micturitions per 24 h from baseline to the end of the 8-week treatment and 20-week follow-up. The secondary outcomes will encompass the change in Overactive Bladder Symptom Score, Overactive Bladder Questionnaire Short Form, and average 24 h values of urgency, daytime micturition, nocturia, and mean volume voided per micturition from baseline to weeks 8 and 20. Urinary nerve growth factor, brain-derived neurotrophic factor, and monocyte chemoattractant protein-1 levels will be measured at baseline and week 8. Adverse events will also be documented. Discussion The results of this trial will provide evidence for the effectiveness and safety of acupuncture in the management of OAB.

Objective To investigate the clinical and pathological characteristics of IgA nephropathy (IgAN) with macrohematuria (MH).Method 1512 consecutive patients with biopsyproven IgAN diagnosed from January 2006 to December 2011 were enrolled,and divided into MH group and control group respectively,according to whether there existed episodes of MH before renal biopsy.The clinical and pathological characteristics were compared between two groups.Patients in MH group were then divided into three groups according to the interval from the last episode of MH to renal biopsy to clarify the concomitant clinicopathological changes associated with occurrence of MH.Results The rate of MH in history was 22.1％.MH group patients had significantly lower serum creatinine,slighter proteinuria,lower prevalence of hypertension and heavier microhematuria than control group (all P ＜ 0.001).The prebiopsy durations were similar in two groups (P=0.627).In MH group,chronic pathological indicators,including global/segmental sclerosis,tubule atrophy/interstitial fibrosis were all slighter (all P＜ 0.001),whereas activity indicators,including necrosis lesions,crescents and mesangial proliferation were all more severe compared with control group (all P ＜ 0.05).Those who underwent renal biopsy within 30 days of the last episode of MH had more severe proteinuria and microhematuria,higher prevalence of necrosis lesions,more severe crescents formation,and endothelial proliferation (all P ＜ 0.05).Conclusions IgAN patients with MH in history have relatively milder clinical and chronic pathological manifestations,however more active pathological changes especially in those who suffer episode of MH recently.

Objective To investigate the effects of hemodialysis (HD) and peritoneal dialysis (PD) on the complications and outcomes after renal transplantation. Methods Clinical data of 402 renal transplant recipients maintained on dialysis for more than 3 months were retrospectively studied and divided into 2 groups: HD group(n=303)and PD group(n=99). Among them, 345 recipients were followed up for an average of (30.2±15.2) months. The impact of HD and PD on the acute rejection, delayed graft function (DGF), infection, chronic rejection and the graft and patient survival rates were analyzed. Results The mean dialysis duration was significantly longer in PD group and the hepatitis B infection rate was significantly higher in HD group. There were no signiticant differences between the HD and PD groups in regarding to primary disease for end-stage renal disease, age, gender, blood pressure, hemoglobin, HLA match, hot and cold ischemia time, and hepatitis C vires infection. The incidence of DGF, acute and chronic rejection, and cytomegalovirus and other infections between HD and PD groups were not significantly different. However, the graft loss happened more frequently in hepatatis B patients than that in non hepatitis B patients (19.23% vs 8.86%, P=0.021), and the post-transplant infection ocurred less in non hepatits B patients with PD. The acute rejection episodes were higher in HD patients who received pretransplant dialysis for more than 12 months (P<0.05). The overall recipients survival rates of HD and PD groups were similar (1-year: HD 94.34%, PD 91.25%;5-year: HD 92.83%, PD 90%), and the same as the graft survival rates in HD and PD groups (1-year: HD 93.21%, PD 96.25%;5-year: HD 87.17%, PD 91.25%). Conclusions The influences of PD and HD on the complications after renal transplantaton, 1-year and S-year recipients and graft survival rates are similar, so both HD and PD can be chosen as the pretransplant dialysis modality. As the incidence of acute rejection increases with time in HD, it is better to shorten the time of pretransplant dialysis to decrease the complication.

Objective To explore relevant factors influencing self-management of diabetic patients and the effects on whole course health education and nursing. Methods Clinical data of 248 diabetic patients who were admitted to Peo-ple's Hospital of Xinchang County from May 2012 to January 2014 were retrospectively analyzed. They were assigned to two groups according to their nursing methods. Control rate of blood sugar, master rate of knowledge on diabetes,self-management rate and satisfaction of patients were compared between both groups. Results Scores of knowledge on diabetes, self-efficacy, social support, age and cultural background were independent influencing factors for self-management of diabetic patients. Control rate of blood sugar, master rate of knowledge on diabetes, self-management rate and satisfaction of patients in the observation group were all higher than those in the control group, and the dif-ferences were statistically significant (P<0.05). Conclusion Patients' age,cultural background,knowledge on diabetes,self-efficacy and social support are main influencing factors for self-management of diabetes. In clinical settings,whole course health education and nursing can be carried out, so as to improve patients' master rate of knowledge on diabetes,and optimize self-management levels.

Objective To investigate the impact of peritoneal albumin leakage on malnutrition-inflammation-atherosclerosis (MIA) syndrome in continuous ambulatory peritoneal dialysis (CAPD) patients. Methods A cross-sectional study of a cohort of 130 CAPD patients without edema or active infection was performed. In order to identify peritoneal transport characteristics in CAPD patients, a standard peritoneal equilibration test (PET) was carried out. For malnutrition and inflammation, serum albumin and high-sensitivity C-reactive protein (hs-CRP) levels were measured. Mean-carotid artery intima media thickness (IMT) was used to determine atherosclerosis. Residual glomerular filtration rate (rGFR) was defined as the average of 24-hour urinary urea and creatinine clearances. Results Pearson and Spearman correlation analysis showed that peritoneal albumin leakage amount was positively correlated with age, body mass index, night dwell time, blood glucose, 4 h D/P creatinine levels and hs-CRP levels (r=0.204, P<0.05 ;r=0.314, P<0.01; r=0.265, P<0.01; r=0.212, P<0.05; r=0.401, P<0.01; r=0.216, P<0.05); whereas it was negatively correlated with diastolic perssure, serum albumin levels, glucose level of dialyzate and peritoneal Kt/V (r=-0.209, P<0.05; r=-0.123, P<0.05; r=-0.271, P<0.01; r=-0.212, P<0.01). Overall, there was no correlation between peritoneal albumin leakage and IMT. Patients was significantly greater (P<0.01), and there was a positive correlation between peritoneal albumin leakage amount and IMT (r=0.650, P<0.01). Conclusions Peritoneal albumin leakage is significantly associated with peritoneal transport characteristics, malnutrition and inflammatory state in CAPD patients. High peritoneal albumin leakage amount is a risk factor for atherosclerosis in patients with rGFR less than 1 ml·min-1(1.73 m2)-1.

OBJECTIVE: To explore the clinical and pathologic features of angioimmunoblastic T-cell lymphoma(AITL) and provide evidence for diagnosis. METHODS: Eighteen AITL patients (9 males and 9 females aged from 14 to 70 years) were retrospectively analyzed in Xiangya Hospital of Central South University from July 2002 to September 2007. RESULTS: Characteristic features at the presentation of AITL included generalized lymphadenopathy, fever, splenomegaly, and skin rashes with polyclonal hyper-gammaglobulinemia and other hematological abnormalities (such as Coombs-positive hemolytic anemia), which often involved the bone marrow and had well-described histologic features. The positive rate for CXCL13 was 93.3%. CONCLUSION Repeated lymphadenbiopsy is helpful for AITL diagnosis. Routine histological and immunohistochemical examinations (especially including CXCL13) play significant role in the diagnosis and differential diagnosis of AITL.

Objective To explore the impact of predictive nursing intervention under the guidance of the"5S"management model on the rehabilitation effect and pulmonary infection rate of hypertensive intracerebral hemorrhage patients.Methods A total of 120 patients with hypertensive intracerebral hemorrhage who were treated at the Second Affiliated Hospital of Wenzhou Medical University from January 2022 to January 2023 were selected as the research subjects.Patients were divided into a predictive nursing intervention group and a conventional nursing group using a random number table method,with 60 patients in each group.The routine nursing group received routine care,while the predictive nursing intervention group received predictive nursing intervention guided by the"5S"management model.The modified Rankin scale(mRS)was used to evaluate the patient's neurological function.The mini-mental state examination(MMSE)was used to evaluate the cognitive function of patients.The differences of mRS and MMSE scores between two groups of patients with different nursing interventions were compared,and the incidence of complications,hospital stay,and disability rate were recorded between both groups.Results After the intervention,the cognitive function score of the predictive nursing intervention group was significantly higher than before the intervention,while the neurological function score was significantly lower than before the intervention.After intervention,the cognitive function score of the predictive nursing intervention group was significantly higher than that of the conventional nursing group(28.02±2.03 vs.24.57±2.25,P＜0.05).The neurological function score was significantly lower than that of the conventional nursing group(1.55±0.67 vs.2.20±0.48,P＜0.05).The hospitalization time and disability rate in the predictive nursing intervention group were significantly lower than those in the conventional nursing group[hospitalization time(days):14.94±6.02 vs.25.33±7.03,disability rate:8.33%(5/60)vs.23.33%(14/60),both P＜0.05].The incidence of pressure injury,lung infection,and urinary system infection was significantly lower than that of the conventional nursing group[pressure injury:1.67%(1/60)vs.10.00%(6/60),lung infection:1.67%(1/60)vs.11.67%(7/60),urinary system infection:0%(0/60)vs.6.67%(4/60),all P＜0.05].Conclusions Under the guidance of the"5S"management model,predictive nursing can significantly improve postoperative cognitive and neurological dysfunction in patients with hypertensive cerebral hemorrhage,reduce disability rates,shorten hospital stay,and reduce the incidence of complications such as pulmonary infections.It has good clinical application prospects.

Objective: To observe the effects of electroacupuncture (EA) at Neiguan (PC6) on arrhythmia during acute myocardial ischemia-reperfusion and the expression of connexin 43 (Cx43) in rats. Methods: A total of 40 Sprague-Dawley male rats were used. Ten rats were randomly selected as the blank group, and the remaining 30 rats were randomly divided into a model group and an EA group, with 15 rats in each group. Before modeling, rats in the EA group received one session of EA intervention at bilateral Neiguan (PC6) for 30 min; the other groups were treated with the same grasping and anesthesia for 30 min without intervention. PowerLab physiological recorder was used to record electrocardiograph within 30 min of infarction. After the experiment, cardiac tissue and serum were collected from rats. Hematoxylin-eosin (HE) staining was used to observe the morphological changes of myocardial tissue in the ventricular infarction area of rats in each group. The expression of Cx43 protein in the myocardium of each group was detected by Western blotting (WB). Enzyme-linked immunosorbent assay (ELISA) was used to determine the activity of Na+-K+-ATPase in myocardial tissue and the serum content of endogenous digitalis-like factor (EDLF) in rats. Results: There was no statistical difference in arrhythmia score between the EA group and the model group, but the total duration and average duration of arrhythmia in the EA group were decreased (P<0.01). HE staining showed that compared with the blank group, myocardial cells in the model group were disorganized and seriously damaged. The pathological changes in the EA group were similar to those in the model group, but the damage was relatively minor. The results of WB showed that compared with the blank group, the Cx43 expression in myocardial tissue of the model group was decreased (P<0.01); compared with the model group, the Cx43 expression in the EA group was increased (P<0.01); compared with the blank group, the Na+-K+-ATPase activity in myocardial tissue of the model group was significantly decreased (P<0.01); compared with the model group, the Na+-K+-ATPase activity in the EA group was increased (P<0.01). ELISA results showed that compared with the blank group, the serum EDLF content in the model group was significantly increased (P<0.01); compared with the model group, the EDLF content in the EA group was decreased (P<0.01). Conclusion: EA at Neiguan (PC6) can delay and reduce the onset of arrhythmia during myocardial infarction in the rat model of myocardial ischemia-reperfusion. Its mechanism of action may be related to the regulation of the Cx43 expression in myocardial tissue, improvement of the activity of Na+-K+-ATPase in myocardial tissue, and increase in the content of serum EDLF.

Objective To investigate the clinico-pathological features and renal outcomes of primary IgA nephropathy (IgAN) with glomerular IgM deposition.Methods Primary IgAN diagnosed with biopsy from January 2006 to December 2011 were recruited.Patients were divided into groups according to IgM deposition (Group A) and without IgM deposition (Group B).In addition,Group A was subdivided into two groups based on the position of IgM deposits as the mesangium (Group A1) and both mesangium and capillary wall (Group A2).Renal outcomes were defined as end stage renal disease (ESRD) and/or the doubling of baseline serum creatinine.Clinico-pathological features were retrospectively compared.Kaplan-Meier was conducted for renal outcomes,and Cox regression model was used to analyze the prognostic value of IgM deposition and the position of IgM deposition in the progression of nephropathy in IgAN patients.Results 939 patients were enrolled with 422 (44.9％) having IgM deposition (Group A).Of the 422 patients,382 patients were divided as Group A 1,whereas 40 patients were noted as Group A2.Compared to Group B,hemoglobin,serum protein,albumin and serum IgG levels in group A were significantly lower,and the cholesterol and serum IgM levels were significantly higher (all P ＜ 0.05).There was no significant difference in serum creatinine,estimated glomerular filtration rate (eGFR),urinary protein,blood pressure and uric acid between group A and B.In terms of pathological manifestations,patients in Group A exhibited more severe histological lesions including glomerular sclerosis,S1,M1 and interstitial inflammatory cell infiltration (all P＜0.05).Immunofluorescence showed that the proportion of IgG,C1q and Fg deposition in group A was significantly higher than that in group B (all P ＜ 0.05).By Kaplan-Meier,cumulative renal survival rate has no significant difference between Group A and B (Log-rank test x2=0.019,P=0.891).Univariate and muhivariable Cox regression analysis showed that IgM deposition had no significant effect on the renal progression in IgAN patients.Subgroup analysis showed that patients in Group A2 exhibited higher urine protein,creatinine and blood pressure,and lower eGFR and serum albumin,also had worse histological lesions including M1,E1 and T1-2 of Oxford classification (all P＜0.05),Immunofluorescencc showed that the proportion of IgG,C1q and Fg deposition in group A2 was significantly higher than that in group A1 (all P ＜ 0.05).By Kaplan-Meier,renal survival rates calculated from outcomes were lower in Group A2 (Log-rank test x2=1 8.207,P ＜ 0.001).In addition,IgM deposited both in the mesangium and capillary wall was a risk factor for renal progression of IgAN patients with IgM deposition by a univariate Cox hazards regression mode and multivariable-adjusted Cox models (HR=3.621,95％CI 1.924-6.814,P＜ 0.001;HR=2.309,95％CI 1.176-4.533,P=0.015respectively).Conclusions The IgAN patients with IgM deposition relatively had more severe clinicopathological changes,especially those with IgM deposited both in the mesangium and capillary wall.In this study,IgM deposition was not found to be an independent risk factor for the prognosis of kidney in IgAN patients.However,IgM deposited both in the mesangium and capillary wall was an independent risk factor for renal prognosis in IgAN patients with IgM deposition.

Objective: To analyze epidemiological characteristics of influenza-like illness outbreaks in mainland China during 2017-2018 surveillance season, and to provide scientific evidence for developing influenza prevention and control strategies. Methods: We collected the data on reported influenza outbreaks in 2017-2018 surveillance season from China Influenza Surveillance Information System and China Public Health Emergency Management Information System and analyzed the data of laboratory-confirmed influenza-like illness outbreaks by descriptive epidemiological methods. Results: During the surveillance season, a total of 2 398 influenza-like illness outbreaks (with 10 or more incidences in an outbreak) in mainland China were reported, involving 87 084 patients, of which 2 323 were influenza outbreaks, involving 85 531 patients. The reported influenza-like illness outbreaks occurred most frequently from November 2017 to January 2018 in both the southern and northern regions and the highest peaks were in December 2017. During the period 1 850 influenza-like illness outbreaks (77.15%) were reported in the southern region, and 548 influenza-like illness outbreaks (22.85%) were reported in the northern region. The most of the outbreaks occurred in primary, secondary schools and nursery care schools, with a total of 2 210 reports (92.16%). And the majority of the outbreaks involved 10-29 incident cases. The dominant isolated virus strains for the outbreaks were influenza B (1 505 outbreaks, 62.76% of all the outbreaks). Conclusion Seasonality of influenza outbreaks were observed in mainland China during 2017-2018 surveillance season and the reported influenza outbreaks were most frequently occurred in autumn-winter season and in southern China. Primary, secondary schools and nursery care schools are high-risk places for outbreaks, and the dominant isolated virus strains for the outbreaks were influenza B.
