Objective To investigate the impact of whole body vibration training combined with intermittent blood flow restriction on the motor function and community activity in elderly stroke patients with hemiplegia.Methods A total of 80 convalescent hemiplegic patients after stroke who were hospitalized in the Rehabilitation Medicine Department of Yichang Central People's Hospital(Xiling Campus)from October 2021 to December 2023 were included and randomly divided into control group(n=25),vibration group(n=28)and combination group(n=27)using the random number table method.All patients received conventional rehabilitation training,on the basis;the vabration group received whole body vibration training,while the combination group received whole body vibration training combined with intermittent blood flow restriction.Before and after 6 weeks of training,the balance function was evaluated with Berg balance scale(BBS),while the gait function was tested with 6-minute walking test(6MWT)and the Community Balance and Mobility scale(CB&M)was used to assess the community activity ability.The community balance and mobility(CB&M)were evaluated in the first and third month after discharge.Results There was no significant difference in BBS,CB&M scores and 6MWT walking distance between the three groups before training(P>0.05).After 6 weeks of training,the three groups showed significant increases in the BBS,CB&Mscores and the walk distance of 6MWT(P<0.001).Furthermore,compared with the control group,the combination group and the vibration group were significantly beter(P<0.05),and there was no signifi-cant difference between the combination group and the vibration group(P>0.05).At the first and third month of follw-up after discharge,the CB&M scores of the three groups were significantly higher than those of the control group(P<0.05),while there was no significant difference between the CB&M scores of the combination group and the vibration group at the first month of follow-up(P>0.05).But the CB&M scores of the combination group was higher than those of the vibration group at the third month of follow-up,and the difference was statistically signifi-cant(P<0.05).Conclusion On the basis of conventional rehabilitation,whole body vibration training combined with intermittent blood flow restriction can significantly enhance balance function,balance confidence,walking ability and mobility in early stage of community life for elderly stroke patients with hemiplegia,potentially facilitat-ing their return to community life.

Primary female urethral adenocarcinoma is rare. This paper reports a case of primary urethral mucinous adenocarcinoma complicated with signet ring cell carcinoma. The patient underwent urethral tumor resection in another hospital. Postoperative examination indicated that the tumor remained, and the tumor was completely removed after urethral tumor resection. After 11 months of follow-up, there was no tumor residue or recurrence.

Objective: Many studies have shown that respiratory syncytial virus persistent infection may be the main cause of chronic respiratory pathology. However, the mechanism is unclear. Cystic fibrosis transmembrane conduction regulator (CFTR) is an apical membrane chloride channel, which is very important for the regulation of epithelial fluid, chloride ion, and bicarbonate transport. CFTR dysfunction will lead to changes in bronchial secretions and impair mucus clearance, which is related to airway inflammation. In our previous study, we observed the down-regulation of CFTR in airway epithelial cells in respiratory syncytial virus (RSV) infected mouse model. In this study, we further investigated the expression and function of CFTR by constructing an airway epithelial cell model of RSV persistent infection. Methods: 16HBE14o- cells were infected with RSV at 0.01 multiplicity of infection (MOI). The expression of CFTR was detected by real-time RT-PCR, immunofluorescence, and Western blotting. The intracellular chloride concentration was measured by N-(ethoxycarbonylmethyl)-6-methoxyquinolium bromide (MQAE) and the chloride current was measured by whole-cell patch clamp recording. Results:16HBE14o-cells infected with RSV were survived to successive passages of the third generation (G3), while the expression and function of CFTR was progressively decreased upon RSV infection from the first generation (G1) to G3. Exposure of 16HBE14o-cells to RSV led to the gradual increase of TGF-β1 as well as phosphorylation of Smad2 following progressive RSV infection. Disruption of TGF-β1 signaling by SB431542 prevented Smad2 phosphorylation and rescued the expression of CFTR. Conclusion:RSV infection can lead to defective CFTR function in airway epithelial cells, which may be mediated via activation of TGF-β1 signaling pathway.

Objective: To investigate the association between fresh fruit consumption and status of glycemic control, among patients with type 2 diabetes mellitus (T2DM). Methods: Using the stratified cluster sampling method, a cross-sectional study was conducted among 19 473 diabetic patients who were under the Disease Management Program related to the National Basic Public Health Service in Changshu county, Huai’an and Qinghe districts of Huai’an city from December 2013 to January 2014, under the combination of fasting plasma glucose (FPG) and haemoglobin A1c (HbA1c) methods, the glycemic control status in T2DM patients was assessed. Multiple logistic regression method was used to explore the relationship between fresh fruit consumption and status of glycemic control among T2DM patients. Results: 62.4% of the T2DM patients reported their amount of fruits intake in the past year. Both the levels of FPG and HbA1c decreased in T2DM patients, when the frequency and amount of fresh fruit consumption were increasing. Compared with patients who did not take fresh fruits, the risk of poor glycemic control in patients with fresh fruit consumption of 1-4 times/week and ≥5 times/week decreased 20% (OR=0.80, 95%CI: 0.73-0.87) and 30% (OR=0.70, 95%CI: 0.62-0.80), respectively. Patients with fruit consumption of 50-99 g/day and ≥100 g/day had lower risk of poor glycemic control, with ORs (95%CI) as 0.71 (95%CI: 0.62-0.83) and 0.68 (95%CI: 0.59-0.78), respectively. Conclusions The association of fresh fruit intake and glycemic control was statistically significant in patients with type 2 diabetes. With the increase of frequencies and amounts of fresh fruit consumption, the levels of FPG and HbA1c showed a decreasing trend. Our findings suggested that fresh fruit intake seemed helpful for glycemic control.

OBJECTIVETo explore genetic mutation and clinical treatment for a patient with globozoospermia.

METHODSHistomorphology of the sperms was studied by Wright-Giemsa staining and transmission electron microscopy. Potential mutation of the DPY19L2 gene was detected by PCR amplification and Sanger sequencing.

RESULTSWright-Giemsa staining showed that all spermatozoa from the patient were round-headed and lacked the acrosome, with the nuclei of sperm head stained in dark and full. Transmission electron microscopy revealed large round sperm heads, with an even layer of unit membrane surrounding the nuclei and dispersed cytoplasmic vacuoles but no acrosomal structure. The patient has harbored a homozygous deletion of the DPY19L2 gene. With intracytoplasmic sperm injection (ICSI) treatment, fertilization rate of the oocytes has reached 28.6%, which resulted in a successful pregnancy. A healthy male was born.

CONCLUSIONThe homozygous deletion of DPY19L2 probably underlies the globozoospermia in this case, for which ICSI has provided an effective treatment. However, there is still a risk of low oocyte fertilization rate or fertilization failure. Further studies are required.

Objective To explore the association of smoking and smoking cessation with glycemic control in male patients with type 2 diabetes. Methods From December 2013 to January 2014, a total of 7763 male patients with type 2 diabetes, who received national basic public health service in Changshu county of Suzhou city, Huai'an and Qinghe districts of Huai'an city, Jiangsu province, were recruited by cluster sampling. Questionnaire survey and anthropometric measurements were conducted, and fasting plasma glucose (FPG) and hemoglobin A1c (HbA1c) levels were measured. Multiple linear regression model was used to evaluate the association of smoking and smoking cessation with glycemic control. Results The prevalence of current smoking was 45.5%in male patients with type 2 diabetes. The levels of FPG and HbA1c increased with number of cigarettes smoked per day compared with non-smokers (P<0.001). Among patients with drug treatment, the average increase of HbA1c level in current smokers with smoking duration ≥30 years and smoking index ≥40 pack-years were 0.27% (95%CI: 0.05%-0.49%) and 0.38% (95%CI: 0.23%-0.53%),respectively. FPG and HbA1c level decreased obviously with smoking cessation years among former smokers (P<0.05). Among the patients receiving no drug treatment, no dose-response relationships were observed between smoking duration, smoking cessation years and levels of FPG and HbA1c. Conclusion Cigarette smoking was negatively related with glycemic control in male type 2 diabetes patients, especially in patients with drug treatment. Smoking cessation may be beneficial for glycemic control. Smoking cessation should be encouraged for diabetes patients as early as possible.

Objective: To explore the impact of renal function injury on diagnostic value of NT-proBNP in patients with heart failure (HF).
Methods: A total of 420 patients with cardiovascular disease at (50-75) years of age were divided into 2 groups based on left ventricular ejection fraction (LVEF): Control group, the patients with normal cardiac function, LVEF≥40%,n=232 and HF group, LVEF<40%,n=188. According to estimated glomerular ifltration rate (eGFR), each group contained 4 subgroups by Normal renal function (eGFR≥90 ml/min·1.73m2), Mild renal injury (90>eGFR≥60 ml/min·1.73m2), Moderate renal injury (60>eGFR≥30 ml/min·1.73m2) and Severe renal injury (eGFR<30 ml/min·1.73m2). The changes of NT-proBNP level at different subgroups were observed and the optimal cut-off values of NT-proBNP for HF diagnosis were measured.
Results: Compared with Control group, HF group had increased blood level of NT-proBNP,P<0.05; NT-proBNP level was negatively related to eGFR (in all patients:r=-0.664, in Control group:r=-0.686 and in HF group:r=-0.721,P<0.05). Within Control group, NT-proBNP level was similar between Normal renal function and Mild renal injury subgroups,P>0.05, while it was much higher in Moderate and Severe renal injury subgroups than Normal renal function subgroup,P<0.05. Within HF group, Severe renal injury subgroup had increased NT-proBNP level than other subgroups,P<0.05. The best cut-off value of NT-proBNP for HF diagnosis in patients with normal or mild renal injury was 1070 pg/mL (sensitivity: 91.8% and speciifcity 72.6%); with moderate renal injury was 7121 pg/mL (sensitivity: 80.2% and speciifcity: 89.7%); with severe renal injury was 33344 pg/mL (sensitivity: 83.3% and speciifcity: 80%).
Conclusion: Moderate to severe renal function injury could increase circulating level of NT-proBNP and therefore, the cut-off value of NT-proBNP for HF diagnosis should be elevated accordingly in patients of HF combing renal injury.

Objective To investigate the influence of breast pure mucinous carcinoma size on sonographic characteristics and diagnostic accuracy.Methods Sonographic characteristics of 101 breast pure mucinous carcinoma in 1 00 patients were analyzed retrospectively.All lesions were divided into three groups according to maximum diameter at ultrasound.These were group Ⅰ with lesions less than 20 mm,group Ⅱwith lesions greater than or equal 20 mm,less than 40 mm,and group Ⅲ with lesions greater than or equal 40 mm.The relationship between lesions size and ultrasound parameters were analyzed.Results There were 38 lesions in group Ⅰ,52 lesions in group Ⅱ and 1 1 lesions in group Ⅲ.The patients age in group Ⅲwere older than that in group Ⅰ(F=3.442,P =0.036).Among these sonographic appearances,only shape (χ2=9.813,P =0.005)and blood flow (χ2=27.952,P =0.000)indicated significant differences.The accuracy of ultrasound diagnosis of breast cancer was 85.1%,the smaller the lesions were,the higher misdiagnosis rate the lesions were.Conclusions With lesions size increased,the lobular and internal blood flow of pure mucinous carcinoma increased.More smaller the lesions were,more higher misdiagnosis rate of lesions were.

Objective To evaluate the efficacy of integrated traditional Chinese medicine(TCM)and western medicine in treatment of acute exacerbations of chronic obstructive pulmonary disease(AECOPD)combined with respiratory failure,TCM syndromes of spleen-kidney-yang deficiency and phlegm-dampness by comparison between the integrated therapy and simple western therapy in treatment of the disease. Methods 160 patients with AECOPD combined with respiratory failure,spleen-kidney-yang deficiency and phlegm-dampness syndrome in the intensive care units(ICU)of Affiliated Hospital of Chengdu University of TCM and other four hospitals were randomly allocated into two groups in this double-blinded,multicenter,prospective,randomized,controlled trial. In the control group (78 cases),western medicine and placebo were given to the patients,and in the treatment group(82 cases), conventional western medicine plus fei-shuai mistura 25 mL were administered,four times per day,the therapeutic course lasting for 2 weeks in both groups. The all-cause mortality,respiratory failure-cause mortality,improvement of modified Medical Research Council(mMRC)Dyspnea Scale grades,6 minutes walk distance(6MWD),the forced expiratory volume in 1 second/forced vital capacity(FEV1/FVC)were observed in the 28 days after the end of treatment. Results In the comparisons between the control and treatment groups,there were no statistical significant differences in the all-cause mortality〔54.87%(45/82)vs. 64.10%(50/78)〕and the cases of FEV1/FVC(both P>0.05)in the 28 days after the end of treatment;the 28 day respiratory failure-cause mortality was significantly decreased〔19.51%(16/82)vs. 33.33%(26/78),P<0.05〕,the number of patients with mMRC Dyspnea Scale grades (1-2)was obviously increased(22 cases vs. 7 cases,P<0.05),and the number of patients with 6 MWD grades (4-6)was markedly enhanced in the treatment group(21 cases vs. 8 cases,P<0.05). Conclusions The integrated TCM and western medicine has better therapeutic results in improvement of the patients' degree of dyspnea, 6 MWD and respiratory failure mortality than simple treatment with western therapy for treatment of patients with AECOPD combined with respiratory failure, spleen-kidney-yang deficiency and phlegm-dampness syndrome. However,in regard to the effect on pulmonary function and all cause mortality,the integrated therapy for treatment of such patients in short term has no significant effect.
