Hemiplegics after stroke are often disabled in sit-to-stand(STS).This article discussed the biomechanics of STS in the hemiplegic stroke patients,in terms of kinematics,kinetics and surface electromyography,and the rehabilitation for the stroke patients with STS dysfunction.It was found that the stability,duration,symmetry of support and degree and se-quence of muscular activation were different when the patients finished the STS task in three foot positions of natural, symmetrical and unaffected foot behind.The early STS rehabilitation training or other rehabilitation may improve the function of the hemiplegic lower extremity to prevent falls and apraxia.

OBJECTIVETo evaluate the efficacy and safety of the combination therapy of Xipayimaizipizi Capsules and Tamsulo- sin in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe randomly assigned 60 BPH patients to a control and a combination group of equal number, the former aged 62.03 ± 10.19 years with a disease course of 3.24 ± 2.18 years and the latter aged 64.77 ± 10.33 years with a disease course of 4.09 ± 2.63 years. We treated the patients in the control group with Tamsulosin at 0.2 mg qd and those in the combination group with Tamsulosin at 0.2 mg qd plus Xipayimaizipizi at 0.5 g tid, respectively, both for 4 weeks. Then, we obtained the mean frequency of nocturnal urination, maximal urinary flow rate (Qmax), residual urine volume, International Prostate Symptom Score (IPSS) , and quality of life scores (QOL) of the patients, and recorded their adverse reactions.

RESULTSBefore treatment, the nocturnal urination frequency, Qmax, IPSS, and QOL were 3.60 ± 1.81, (10.40 ± 3.53) ml/min, 22.47 ± 8.58, and 4.43 ± 1.50 in the control group, as compared with 3.43 ± 1.61, (10.14 ± 3.43) ml/min, 21.93 ± 8.79, and 4.73 ± 1.31 in the combination group. After 4 weeks of medication, the combination group showed more significant improvement than the control in the nocturnal urination frequency (1.30 ± 1.18 vs 2.27 ± 1.60), Qmax ([13.85 ± 3.15] vs [14.36 ± 3.03] ml/min), IPSS (13.00 ± 1.53 vs 17.20 ± 8.43), and QOL (2.57 ± 1.61 vs 2.93 ± 1.68), all significantly better than the baseline (P < 0.05). The combination therapy achieved remarkable improvement as compared with the control in the nocturnal urination frequency (- [2.13 ± 1.11] vs -[1.73 ± 1.07]), IPSS (- [8.93 ?6.01] vs -[4.80 ± 3.87]), and QOL (- [2.17 ± 1.12] vs -[1.50 ± 1.01]) (P < 0.05), but exhibited no significant differences from the latter in Qmax ([3.72 ± 2.281 vs [3.95 ± 2.53] ml/min) and residual urine volume (- [34.30 ± 37.43] vs - [26.43 ± 30.49] ml) (P > 0.05). Adverse reactions were found in 5 cases in the combination group (16.67%) and 3 cases in the control (10%) , with no remarkable differences between the two groups (P > 0.05).

CONCLUSIONThe combination therapy of Xipayimaizipizi Capsules and Tamsulosin can improve the symptoms of BPH and the patients quality of life of.

Objective: Sex differences have been observed in many aspects of schizophrenia, including cognitive deficits. Despite extensive research into the relationship between metabolic factors and cognitive deficits in schizophrenia, few studies have explored the potential sex difference in their association. Methods: We recruited 358 schizophrenia patients and 231 healthy controls. The participants underwent measurements of body mass index (BMI), waist circumference, blood pressure, triglycerides, high-density lipoprotein cholesterol, and fasting blood glucose. Metabolic risk factors included abdominal obesity, hypertension, hyperglycemia, and dyslipidemia. A collection of these metabolic risk factors has been defined as metabolic syndrome. These diagnoses were based on the criteria of the National Cholesterol Education Program’s Adult Treatment Panel III. Cognitive performance was measured using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). A descriptive analysis, difference analysis, and linear regression model were used to identify the metabolic risk factors for cognitive function in schizophrenia. Results: Our findings revealed sex differences in the rate of abdominal obesity and hypertension in schizophrenic patients. Additionally, we observed sex differences in the association between metabolic risk factors and cognitive impairment in schizophrenia. Specifically, hyperglycemia was associated with the immediate memory index score of RBANS in male patients, while dyslipidemia was associated with language, attention, delayed memory index scores, and RBANS total score in female patients. Conclusion Our results suggest that sex should be considered when evaluating the impact of metabolic disorders on the cognitive function of schizophrenic patients. Moreover, our study identifies hyperglycemia and dyslipidemia as potential targets for precise treatment by sex stratification, which could benefit the improvement of cognitive impairment in schizophrenic patients.

OBJECTIVETo investigate the influence of sex on the cough-preventing effect of target-controlled infusion(TCI)of remifentanil during anesthetic emergence.

METHODSA total of 25 female(group F)and 25 male(group M)patients undergoing thyroidectomy were recruited in the current study. Anesthesia was maintained with sevoflurane and remifentanil TCI.At the end of the surgery,inhalational anesthetics were discontinued,and remifentanil TCI at an effect-site concentration(Ce)of 2.0 ng/ml was maintained during emergence until extubation. The cough score,blood pressure,and heart rate(HR)during peri-extubation period as well as the respiratory rate,calm score,and sore throat score after extubation were evaluated.

RESULTSDuring extubation,the proportion of patients with no cough or just a single cough was significantly higher in group F than in group M(88% vs. 64%,P=0.047). Mean arterial pressure(P=0.025,P=0.037)and HR(P=0.035)were significantly increased during extubation compared with preoperative levels in group M.

CONCLUSIONSSex may influence the cough-preventing effect of remifentanil TCI during anesthetic emergence. At a Ce of 2.0 ng/ml,remifentanil has better cough-preventing effect and more stable hemodynamic status in females than in males.

This study was aimed to investigate the relevance of nilotinib in combination with tetrandrine (Tet) on reversing multidrug resistance and inducing apoptosis of K562/A02 cell line and its mechanism. Methyl-thiazol tetrazolium (MTT) assay was employed to examine the pharmacological effect of nilotinib or Tet alone on K562/A02 cell line, the IC(50) of daunorubicin (DNR) on K562/A02 cell line treated with nilotinib and Tet was calculated; the flow cytometry (FCM) was employed to detect the apoptosis rate of K562/A02. The expression of bax/survivin mRNA was determined by RT-PCR, and the expression of bax/survivin protein was assayed by Western blot. The results showed that after being treated by 5 nmol/L nilotinib or 1.0 µml/L Tet for 48 hours, IC(50) of DNR to K562/A02 was 5.71 ± 0.72 mg/L or 6.52 ± 0.43 mg/L, respectively, while in their combined treatment, IC(50) decreased to 3.12 ± 0.13 mg/L. Nilotinib or Tet alone could increase DNR-inducing apoptosis rate of K562/A02 cell, while the apoptosis rate of K562/A02 increased remarkably in combination treatment of nilotinib with Tet. After being treated with 5 nmol/L nilotinib or 1.0 µml/L Tet alone for 48 hours, the expressions of bax mRNA and BAX protein was up-regulated, while both effects were more obvious in combination treatment of nilotinib with Tet. Treatment with 5 nmol/L nilotinib or 1.0 µmol/L Tet alone for 48 hours down-regulated the expression of survivin mRNA and its protein, while treatment of nilotinib in combination with Tet had more significant effect on down-regulation of their expression. It is concluded that the K562/A02 cells are resistant to DNR, nilotinib or Tet alone both can partially reverse resistance of K562/A02 cells to DNR, increase the apoptosis rate of K562/A02 cells. Combination of nilotinib with Tet shows obvious synergistic action, mechanism of which may associate with up-regulation of bax mRNA and BAX protein expressions and down-regulation of survivin mRNA and its protein expressions.

To clone human interleukin-26 (hIL-26) and express it in E. coli efficiently. Two pairs of primers were synthesized according to the hIL-26 gene reported on GenBank. The hIL-26 gene was cloned by nest PCR following the first round RT-PCR from human peripherial blood monocytes total RNA, and then the PCR product was cloned into pMD18-T vector. Colony PCR, restriction analysis and sequence analysis showed that the gene cloned was the same as the reported hIL-26. The recombinant was cut with BamHI and EcoR I to obtain the hIL-26 fragment, and then the fragment was inserted into pBV220 which was cut with the same enzymes. The recombinant expression vector was induced to express hIL-26 at 42 degrees C, SDS-PAGE analysis showed that the recombinant protein accounted for up to 20% of the whole protein of E. coli, and the protein was also confirmed by Western blotting. Purity of the protein was found to be above 90% after purified with molecular sieve. After renaturalized with glutathione buffer, the promoting effect of it on the production of IFN-y in PBMC was detected by RT-PCR. A recombinant bacterial strain for expressing hIL-26 with biological activity was constructed successfully.
