Objective To explore the diagnostic value of ultrasonography in acute abdomen of women.Methods 269 women with acute abdomen were examined with ultrasonography,the results were compared with clinical and pathological data.Results Of 269 cases,78 cases of ectopic pregnancy,26 cases of ovarian cyst torsion,44 cases of endometriosis("chocolate" cyst),33 cases of ruptured corpus luteum cyst,69 cases of acute pelvic inflammatory mass,6 cases of ovarian cyst rupture,2 cases of pedical of subserous myoma,5 cases of ovarian teratomas,2 cases of ovarian fibromas and 4 cases of red degeneration of uterine myoma were diagnosed by sonography.In comparsion with pathological results,the accorded rates of ultrasonography were 83.3%,84.6%,81.8%,72.7%,82.6%,66.7%,50%,60%,50% and 50% respectively.Conclusion As its convenience and rapid,ultrasonography plays an important role for the diagnosis of acute abdomen in gynecology.

Objective To investigate the clinical efficacy of dexmedetomidine combined with ropivacaine for ilioinguinal and iliohypogastric nerve block in elderly patients undergoing inguinal her-nia surgery.Methods Sixty elderly patients undergoing inguinal hernia surgery were randomly divided into dexmedetomidine group (group D)and control group (group C),30 patients in each group.All patients received ilioinguinal and iliohypogastric nerve block by the same anesthesiologist. 0.375% ropivacaine and dexmedetomidine 1 μg/kg 20 ml were used in ilioinguinal and iliohypogastric nerve block in group D,while 0.375% ropivacaine 20 ml were used in ilioinguinal and iliohypogastric nerve block in group C.Sensory block onset time and blockade duration were recorded.Side effects were recorded in both groups.Results Sensory block onset time in group D was significantly shorter than that in group C (10.6±4.3 min vs 14.4±5.1 min,P <0.05).Sensory block durations in group D was significantly longer than that in group C (832.7±136.6 min vs 669.8±140.1 min,P <0.05). There were two bradycardia cases in group D.No adverse reactions or anaesthesia complications oc-curred in all patients following postoperative follow-up.Conclusion Dexmedetomidine combined with ropivacaine can be used in ilioinguinal and iliohypogastric nerve block safely,and dexmedetomidine shortens the onset time and prolonged the duration of sensory block.

BACKGROUND:Brain microvascular endothelial cel s (BMECs) are important tools in the field of neuroscience research;therefore, how to obtain highly purified BMECs is a key and difficulty in vitro.
OBJECTIVE:To develop a simple method of isolating and culturing highly purified BMECs.
METHODS:C57BL/6 mice aged 6-8 weeks old were selected, and microvessels were obtained using enzyme digestion and gradient centrifugation. Further, endothelia cel s were purified by certain drugs, fol owed by identified by CD31 and GFAP immunofluorescence staining. The expression of Claudin-5 was detected using immunofluorescence staining with anti-Claudin-5 antibody.
RESULTS AND CONCLUSION:Mouse BMECs grew and arranged in spiral or cobblestone-like. Immunofluorescence staining showed that the purity of BMECs reached above 99%and Claudin-5 was highly expressed. In conclusion, a simple method of easy accessibility is developed to obtain highly purified primary mouse BMECs.

OBJECTIVE:To study the effects of rosiglitazone(RH)on body weight,FPG,FFA and other indicators in diabe-tes model rabbit. METHODS:18 rabbits were evenly randomized into control group,model group and dextran group. The latter 2 groups were given alloxan intravenously to induce diabetes model. 3 groups were given RH(0.5 mg/kg)intragastrically,and dex-tran group was additionally given dextran 40 glucose injection(5 ml/kg)intravenously,once a day,for consecutive 3 weeks. Body weight,serum level of FPG,FFA,AngⅡ and NO were determined before and after medication. RESULTS:Compared with be-fore medication,body weight of rabbits in control group were increased after medication,while the levels of FFA and AngⅡ were decreased;the levels of FPG and FFA were decreased in model group;body weight of rabbits were decreased in dextran group af-ter medication,with statistical significance (P<0.01 or P<0.05);other indicators had no statistically significant difference (P>0.05). The level of FFA in dextran group was higher than in model group after medication,with statistical significance(P<0.01). CONCLUSIONS:Rosiglitazone can lead to weight gain by a mechanism which reduce the level of FFA.

Autophagy is an active research area in the biomedical field as its role has been identified in many physiological and pathological processes. Accordingly, there is a growing demand to identify, quantify and manipulate the process accurately. Meanwhile, there is great interest in identifying compounds that modulate autophagy because they may have applications in the treatment of a variety of autophagy-related diseases. In this review, we summarize the current status of autophagy screening systems to facilitate identification of autophagy modulators.
