Objective To study the applicability of hysteroseopy for abnormal uterine bleeding of women and to analyze the etiology.Methods 679 cases of women with abnormal uterine bleeding were examined by hysteroscopy,whose situations were showed first under bimanual or trimanual examinations,then trams abdominal or traps vaginal B-ultrasonograpy.Results The postive rate of uterie abnormality was 98.6% detected by hysteroscopy and biopsy.Endometrial hyperplasia and endometrialpolyp were the main cause of abnormal uterine bleeding,which occupied 56.7%,then were myoma and endometritis.Women of child-bearing age were the largdy group that in volved.Conclusion Hysteorscopic examination was useful for abnormality uterine bleeding of women.We can underatand the relationship with abnormal uterine bleeding and intra-uterine disease,and the distribution of the different diseases in different age to enhance accurate diagnosis.

Objective To elucidate the effects of endothelin-1(ET-1) on expression of extra-regulated kinase 1(ERK 1), cell cycle and changes of Ca 2+ in activated hepatic stellate cells (HSCs). Methods Effects of different concentra tions of ET-1 on ERK 1 expression were determined by Western blotting. Effects of ET- 1 on cell cycle were observed by flow cytometry(FCM) analysis. Effects of ET-1 on changes of calcium concentration and cell area were observed by laser scanning confocal microscopy (LSCM). Results ET-1 could inhibit the expression of ERK 1 i n a dose-dependent manner, compared with the control, the expression of ERK 1 in E T-1 highest concentration group decreased 10.91%?3.36% (P

Objective: To investigate the effects of five kinds of flavonoids (calycosin, formononetin, ononin, isoliquiritigenin, and medicarpin) from Hedysari Radix on promoting osteogenic differentiation of rat bone marrow stromal cells (rBMSCs) and rat calvarial osteoblasts (ROBs). Methods: rBMSCs were isolated according to plastic adherence. ROBs were isolated by enzyme digestion method. The proliferation of rBMSCs and ROBs were detected by MTT assay. ALP activity and calcium content of rBMSCs and ROBs cells were detected by alkaline phosphatase kit and calcium kit. Mineralized nodule formation was detected by alizarin red staining. Results: The five components could promote proliferation, increase ALP activity, increase calcium content, and increase the area and number of calcified nodules of rBMSCs and ROBs (P < 0.05). Among them, calycosin had the best effect on promoting the osteogenic differentiation of rBMSCs, and medicarpin promoted the osteogenic differentiation of ROBs with the best effect, followed by calycosin. Conclusion: Five flavonoids promoted the improvement of osteogenic function, while calycosin has better osteogenic activity on rBMSCs and ROBs and can be used as an excellent osteoinductive factor.

[Objective]To investigate the effects of YIGUTANG contaning serum on osteoblasts proliferation which was from the skull of newborn SD rat in vitro.[Methods] The osteoblast from newborn SD rats’skull adopted, take the method of collagenase-pancreatic enzyme digestion,then respectively culture these osteoblasts with different concentration of the YIGUTANG drug containing serum fluid together.[Results]YIGUTANG drug containing serum could stimulate the proliferation of osteoblast, and the high,the middle and the low concentrations groups contrasted with the control group, all could promote the proliferation of cell .The drug containing serum groups had insignificant difference from the blank control group(P

AIM: To study Qinzhi Capsule(Radix Scutellaniae,Fructus Gardeniae) against virus and bacteria. METHODS: The mice were infected separately by Ⅰ、Ⅱ type flu virus,staphylococcus aureus or pneumococcus in the experiment.The protective action of Qinzhi Capsule on them was observed in vivo.and detemined mininum inhibition concettation(MIC). RESULTS: Qinzhi Capsule could prolong markedly the survival periods of mice(P

AIM: To study the anti-inflammatory,analgesic and antipyretic effects of Qinzhi Capsule(Radix Scutellariae,Fructus Gardeniae,etc). METHODS: Qinzhi Capsule was taken orally.The experimental methods were as follow: abdomen capillary permeability in mouse induced by actetic acid,mouse ear swell induced by dimethylbenzene,mouse pain threshold induced by heat stimulation,animal fever induced by yeast to rat and endotoxin to rabbit,et al. RESULTS: Qinzhi Capsule could inhibit markedly the increase in abdomen capillary permeability in mouse induced by acetic acid(P

AIM: To determine the suitable condition and the optimal parameters for the extraction and purifiction process of total flavonoid compounds in Scutellaria baicalensis. METHODS: It was investigated by orthogonal experiment design of form L_9(3~4) with the extraction percentage of the total flavonoid compounds and baicalin from Scutellaria baicalensis as the standard. RESULTS: The optimal condition of extraction was with water as much as ten times of the medicine amount and was boiled for 2 h and three times,and the optimal condition of purifiction was as follows: solution concentration 0.25 g(crude medicinal materials) /mL,adjusting pH to 2,80 ℃ heat preservation up to 60 min, 50% alcohol as precipitant and the precipitated adjusted pH to 4.0. CONCLUSIONS: The optimal process is rational,practical and adapted to industry production.

Objective To summarize our experience in choledochofiberscopic treatment for residual stones of biliary tract. Methods 1105 cases of residual stones of biliary tract diagnosed and treated with choledochofiberscope in the past 19 years were reviewed retrospectively. Results The 1067 patients with residual stones of bile duct were treated with choledochofiberscope for 1483 times altogether. The stones were completely removed in 1035 cases, while the stones were not cleared in other 32 cases. The clearance rate of residual stones was 97.0%(1035/1067). No patient died of choledochofiberscopic treatment. Conclusions Choledochofiberscopic treatment plays an important role in the treatment of residual stones of bile duct, because it not only reduces residual stones of bile duct to avoid repeated operation, but also has some advantages such as excellent safety, minimal invasion, low cost and quicker recovery.
