Objective To explore the effect of biliary obstruction caused acute acalculous cholecystitis (AAC) on ultrastructure of gallbladder interstitial cells of Cajal (ICCs),and the possible mechanism of impaired contraction of gallbladder smooth muscle. Methods Total 60 healthy adult guinea pigs were in this study. The guinea pigs AAC model was induced by common bile duct ligation (BDL). The guinea pigs were divided into five groups equally,including sham control group (Sham),BDL for 12 hours (BDL-12),24 hours (BDL-24),48 hours (BDL-48) and 72 hours (BDL-72)groups. The gallbladder specimens were collected by the end of study. Gallbladder pathological changes were observed with HE staining under light microscope. Three muscle strips were collected of each gallbladder,fixed in constant temperature water bath with different concentration of eight peptide cholecystokinin agonist (CCK-8,1010 mmol/L,10-9 mmol/L,10-8 mmol/L,10-7 mmol/L and 10-6mmol/L),acetylcholine (Ach,10-8 mmol/L,107 mmol/L,10-6 mmol/L,10-5 mmol/L,10-4 mmol/L)and potassium chloride (KC1) (60 mmol/L). The contraction activity of gallbladder muscle strips was recorded by tonotransducer. The ultrastracture changes of gallbladder ICC in sham,BDL-12 and BDL-72 groups was examined by transmission electron microscopy. Results There was no obvious inflammation in Sham and BDL-12 groups. Compared with sham group,there were significant differences of biology score of gallbladder in BDL-48 and BDL-72 groups (P<0. 05). After adding CCK-8,Ach and KC1,the contraction amplitude of gallbladder muscle increased in each group,and in dose-dependent manner. Compared with sham group,the effect value of each other groups decreased significantly (P<0. 05). Compared with sham group,the morphology of ICC changed in BDL-12group,and more obvious in BDL-72 group. Conclusion Biliary obstruction can induce AAC. At the earlier stage of ACC,the impaired contraction of gallbladder smooth muscle present even without gallbladder inflammation occurrence. ICC may play an important role in impaired contraction.

ObjectiveTo investigate the genomic and non-genomic effects of 17β-estradiol on gallbladder smooth muscle strips of guinea pig and their possible mechanism. MethodsAfter ovariectomized operation (OVX) and subcutaneous injection of 17β-estradiol, the contents of serum estradiol and cholecystokinin-octopeptide (CCK-8) of the sham operation group (Sham) guinea pigs, the OVX group, the OVX and subcutaneous injection 17β-estradiol for 1 day (OVX+E2, 1 d), 3 days (OVX+E2, 3 d) and 7 days (OVX+E2, 7 d) were detected by EILSA respectively. The effects of CCK-8/Ach on constriction of gallbladder muscle strip were observed among various groups by using tension transducer, and the acute effects of 17β-estradiol on guinea pig gallbladder smooth muscle strips were observed to probe its possible mechanism. ResultsCompared with the Sham group, the serum contents of estradiol and CCK-8 decreased in OVX group (P< 0. 05) whereas the sensitivity of OVX guinea pigs gallbladder muscle strips to CCK-8/Ach increased (P<0.05). With the extension of the subcutaneous injection 17β-estradiol time (for 1, 3, 7 days), both the serum estradiol and CCK level increased (P< 0.05) while the guinea pig gallbladder strips sensitivity to CCK-8/Ach decreased (P<0.05).17β-estradiol at concentration ranging from 10 9 to 10-7 mol/L have no effect on the guinea pig gallbladder strips contraction (P>0.05), but at concentration of 10-6 and 10 5 mol/L, it can inhibit the gallbladder contraction (P<0.05). The blocking agents, such as nimodipine, atropine, devazepide, ICI 182,780 and Y-27632, can block the inhibited effects of 17β-estradiol. ConclusionThe 17β-estradiol can affect the gallbladder motility, both by genomic and non-genomic pathway.

OBJECTIVE:To study clinical effect of argatroban for progressive stroke patients of different cerebral ischemic ranges. METHODS:A total of 116 progressive stroke patients selected from neurology department of our hospital during Feb. 2015-May 2016 were divided into anterior circulation (ischemia) group (n=60),posterior circulation (ischemia) group (n=50) and lacunar(cerebral infarction)group(n=6)according to cerebral ischemic ranges. They all received routine treatment combined with argatroban,and given continuous intravenous infusion of argatroban 60 mg/d on the day and 2nd day of disease aggravation, and then continuous intravenous infusion of argatroban 5th day after relieving,3 h/time,bid,7 d as a treatment course. NIHSS scores,modified RANKIN (mRS) scores,APTT and ADR were compared among 3 groups. RESULTS:Forteen days after treat-ment,NIHSS scores and mRS scores of 3 groups were decreased significantly compared to before treatment,with statistical signifi-cance (P<0.05). There was statistical significance between anterior circulation group and posterior circulation group (P<0.05). Two hours after treatment,APTT of 3 groups were prolonged significantly,especially in lacunar group,with statistical significance (P<0.05). Forty hours after treatment,APTT of 3 groups were recover to normal,without statistical significance (P>0.05). No obvious ADR was found in 3 groups. CONCLUSIONS:Argatroban shows significant therapeutic efficacy for progressive stroke of different ischemic ranges with good safety;especially for the patients with anterior circulation ischemics stroke,the effect is quick and anticoagulant effect is significant.

ObjectiveTo study the different clinical effects of using 5 kinds of hemostatic surgeries to manage the intractable postpartum hemorrhage and analyse the risk factors of failed hemostasis.Methods From Jan.2007 to Jul.2011,96 patients with intractable postpartum hemorrhage were studied retrospectively and grouped by the first step surgical treatment.The hemostatic surgeries included uterine tamponade (tamponadegroup ), pelvicbloodvessels ligation(ligationgroup), pelvical arterial embolization (embolization group), uterine compression sutures (sutures group)and uterine compression sutures combining tamponade (combined group).The intraoperative and postoperation datum were compared among groups,so dose the treatment outcomes.Multivariate analysis were used for failed hemostasis.Results( 1 ) The blood loss of 96 patients ranged from 1200 to 9100 ml,and 71 patients had a succeed hemoatasis after employing these surgeries and 25 failed.(2) The blood loss before hemostasis surgeries in tamponade group and embolization group was statisically greater than in sutures group ( P < 0.05 ).Blood loss during the hemostasis surgeries in ligation group was statistically greater than in embolization and sutures groups ( P <0.05).The operating time of embolization group was statistically shorter than ligation group,sutures group and the combined group (P < 0.05 ).(3) Fine of 96 patients had uterine atony and 43 had a successful hemostasis with the success rate about 78%.Forty-six had placenta previa and 39 success with success rate 85%.Thirty-three had placenta accrete and 13 of which succeed in hemostasis with success rate about 39%.In patients with uterine atony and placenta previa,the difference of hemostasis rate in groups had no statistically significant ( P > 0.05 ).In patients with placenta accrete,the hemostasis rate in embolization group was higher than in others groups (P < 0.01 ). (4) The multivariate analysis found that scar uterus,placenta accrete and coagulation defects were the risk factors of failed hemotasis.The OR value respectively was 2.9 (95 % CI:1.1 - 7.6 ),17.9 ( 95 % CI:5.6 - 56.3 ) and 16.2 ( 95 % CI:3.2 - 83.5 ).Embolization had some extent of protective effection ( OR =0.9,95 % CI:0.8 - 0.9 ).Conclusions ( 1 ) Five kinds of hemostatic surgeries were all effective.Though the success rate among groups did show statistical difference,pelvical arterial embolization has the comparative advantage of shorter operating time,less operating blood loss and higher success rate in placenta accrete.(2) Since scar uterus,placenta accrete and coagulation defects were the risk factors of failed hemostasis,sufficient preparation should be made for patients with these risk factors and the hemostatic surgeries should be choosed individually.
