This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.

According to the theory of in vitro radioassay, using TSHAb as binder and 125I-staphylococcal protein A (125I-SPA) as tracer agent, a new method for detecting the abnormal immunoglobulin (aIgG) in the sera of patients with Graves disease (GD) was reported. In the initial study of the method, the most appropriate interacting conditions of TSHAb with aIgG were explored and compared with ELISA using ganglioside (GLS) as a binder. The relationship between aIgG and thyroid-stimulating imunoglobulin(TSI) was probed into. The results showed that TSHAb could interact specifically with aIgG in vitro; but it could not interact with IgG from sera of normal subjects, systemic lupus erythematosis (SLE) patients and diabetic patients. With aIgG as an evaluating index, the mean value in 29 normal subjects was 1. 06?0. 17. When the sera of 72 patients with GD in different clinical stages were studied, the aIgG index was positive in 83% of untreated GD patients (n = 24), in 12% of GD patients in clinical remission (n = 25) and in 82% of relapsed GD patients (n = 23). Very significant difference was observed between normal subjets and untreated and relapsed patients with GD (P

The mechanisms of rHu-EPO attenuating the apoptosis after myocardial infarction in rats were studied. Thirty-two rats were divided into three groups: sham operation group (Sham), acute myocardial infarction group (MI) and rHu-EPO-treated group (MI+ EPO). Acute myocardial infarction model was made by ligating the anterior descending coronary artery. rHu-EPO was administered i. p. in MI+EPO group at the dose of 5 000 IU/kg body weight immediately after the ligation. Each rat in MI+EPO group received the same dose of rHu-EPO daily the next 6 days. On the 14th day all rats underwent hemodynamic measurements and then killed. The samples were examined with HE stain, immunohistochemistry technique (bcl-2, bax) and TUNEL dyeing. The results showed that hemodynamic function in MI+ EPO group was much better than in MI group. The number of the cells positive for bax and TUNEL in MI+ EPO group was less than that in MI group. The number of the cells positive for bcl-2 in MI+ EPO group was more than that in MI group. These findings suggested that rHu-EPO could treat myocardial infarction by preventing apoptosis and attenuating post-infarction deterioration in hemodynamic function.

According to the designed specific primers of gene fragment based on the Salvia miltiorrhiza transcriptome data, a full-length cDNA sequence of SQS2 from S. miltiorrhiza f. alba was cloned by the method of reverse transcription polymerase chain reaction (RT-PCR). The SmSQS2 cDNA sequence was obtained, this sequence is named SmSQS2 and its GenBank registration number is KM244731. The full length of SmSQS2 cDNA was 1245 bp, encoding 414 amino acids including 5'UTR 115 bp and 3'UTR 237 bp. Sequence alignment and phylogenetic analysis demonstrated that SmSQS2 had relative close relationship to the SQS2 of S. miltiorrhiza. The induction of E. coli [pET28-SQS2] in different temperature, induction time, IPTG concentrations and density of inducing host bacterium (A600) were performed, Shaking the culture at 30 degrees C until the A600 is approximately 0.6 and add IPTG to final concentration of 0.2 mmol x L(-1), and then the optimal expression of SmSQS2 recombinant protein were accumulated after the induction time of 20 h. The research provided important base for the study of sterol and terpene biosynthesis of SQS2 in S. miltiorrhiza f. alba.

Objective To observe the position and mobility of the tape after tension-free vaginal tape-obturator(TVT-O) surgery using transperineal two and three dimensional ultrasonography in patients with stress urinary incontinence.Methods A total of 32 patients with stress urinary incontinence who had TVT-O surgery and cured were enrolled.Transperineal two and three dimensional ultrasonography were performed after operation 3 months later.Both the position,morphology and mobility of the tape at rest and during Valsalva menuaver were observed.Results The tapes were mainly located in the 1/3 connection of the middle and distal urethra.The length of the urethra and the length of the urethra between the bladder neck and the proximal tape at valsalva menuaver were longer than those at rest.The tapes moved front-down at valsalva manuaver according to the mean distance between the tape and the symphysis pubis.The angles of the tapes were smaller at valsalva manuaver without significant difference.Conclusion It is useful to observe the position,morphology and mobility of the tape using transperineal two and three dimensional ultrasonography.The changes of the position and morphology of the tapes at valsalva menuaver were not significant.But the tapes can strengthen the urine control in the middle of urethra.

Objective To investigate the effects of total flavonoids in Gingko Biloba on glucose and lipid metabolism and liver function in rats with insulin resistance. Methods Forty SD rats were randomly divided into normal control group,model group,total flavonoids in Gingko Biloba group and rosiglitazone group(positive drug control group)(n=10).Models of insulin resistance were established by high glucose and high fat diet in model group,total flavonoids in Gingko Biloba group and rosiglitazone group.After treatment for 12 weeks,serum glucose,serum lipids,and parameters of insulin resistance,liver function and anti-oxidation capability were detected in each group,and histologic observations of liver tissues were conducted with adipose staining. Results The serum glucose,insulin resistance index(HOMA-IR),insulin action index(IAI),serum total cholesterol(TC),triglyceride(TG),liver malondialdehyde(MDA) and serum transaminase activity in total flavonoids in Gingko Biloba group were significantly lower than those in model group(P

AIM: To investigate the effect of interleukin-13 (IL-13) on cell proliferation and interleukin-6 (IL-6) production in mesangial cells. METHODS: Cell proliferation was tested by MTT method. The protein synthesis of IL-6 in mesangial cells was measured by ELISA. The expression of IL-6 mRNA in mesangial cells was evaluated by RT-PCR. RESULTS: IL-13(1 ?g/L-100 ?g/L) inhibited the proliferation of mesangial cell in a dose-dependent manner. Both mRNA and protein of IL-6 in mesangial cells were increased significantly in the presence of LPS and this increase could be reversed by IL-13 (1?g/L-100?g/L). However, this increase could not be reversed by IL-13 if the dose was lower than 0.1?g/L and if the mesangial cells were cultured in 5% FCS RPMI1640. CONCLUSION: IL-13 could inhibit IL-6 expression induced by LPS in mesangial cells . We suggested that IL-13 may be an inhibitory cytokine in the regulation of the mesangial cell proliferaltion and inflammatory reaction in glomerulonephritis.
