Objective:To investigate the efficacy of magnesium sulfate combined with labetalol on severe preeclampsia and the effects on serum levels of soluble intercellular adhesion molecule-1 (sICAM-1), vascular endothelial growth factor (VEGF) and pregnancy associated plasma protein-A (PAPP-A).Methods:Eighty-five patients with severe preeclampsia who received treatment in Jinhua Municipal Central Hospital between January 2019 and June 2020 were included in this study. They were randomly assigned to receive treatment either with magnesium sulfate (control group, n = 42) or magnesium sulfate combined with labetalol (observation group, n = 43). Before and after treatment, 24-hour dynamic blood pressure, 24-hour urinary protein excretion and umbilical artery hemodynamics were determined. In addition, serum levels of sICAM-1, VEGF and PAPP-A were detected. Results:After treatment, 24-hour mean arterial pressure, 24-hour urine protein excretion in the control and observation groups were significantly decreased compared with before treatment. After treatment, the 24-hour mean arterial pressure [(116.45 ± 9.63) mmHg vs. (120.74 ± 9.48) mmHg] and 24-hour urine protein excretion [(1.85 ± 0.52) g vs. (2.33 ± 0.75) g] were significantly lower than those in the control group ( t = 2.069, 3.436, both P < 0.05). The umbilical artery resistance index in the control group, and the peak systolic velocity/end-diastolic velocity ratio and the umbilical artery resistance index in the observation group were significantly decreased after treatment compared with before treatment (all P < 0.05). After treatment, the peak systolic velocity/end-diastolic velocity ratio in the observation group was significantly lower than that in the control group [(2.80 ± 0.50) vs. (3.01 ± 0.45), t = 2.034, P < 0.05]. After treatment, serum sICAM-1 and PAPP-A levels were significantly decreased, and serum VEGF level was significantly increased, in each group (all P < 0.05). After treatment, serum levels of sICAM-1 [(548.52 ± 102.74) mg/L vs. (647.52 ± 124.15) mg/L, t = 4.009, P < 0.05] and PAPP-A [(111.74 ± 28.52) U/L vs. (134.24 ± 35.96) U/L, t = 3.200, P < 0.05] in the observation group were significantly lower than those in the control group, and serum VEGF level in the observation group was significantly higher than that in the control group [(32.12 ± 7.45) ng/L vs. (28.17 ± 6.23) ng/L, t =2.659, P < 0.05]. There was no significant difference in the incidence of poor pregnancy outcome between the control and study groups ( P > 0.05). Conclusion:Magnesium sulfate combined with labetalol exhibits good therapeutic effects on severe preeclampsia. The treatment method can improve umbilical artery hemodynamics, and its mechanism may be related to its effect on vascular endothelial function.

Objective To investigate the effects of dexmedetomidine preconditioning on ischemia-reperfusion(I/R) injury to isolated rat hearts.Methods Twenty-four male Wistar rats weighing 230-260 g were anesthetized with intraperitoneal 10％ chloral hydrate 400 mg/kg and heparin 500 IU/kg.Their hearts were excised and perfnsed in a Langendorff apparatus with K-H solution saturated with 95％O2-5％CO2 at 37 ℃.Twenty-four isolated rat hearts were randomly divided into 3 groups after 10 min of equilibration(n =8 each):group I/R,dexmedetomidine 0.23,2.30 ng/ml preconditioning group (groups D I,D Ⅱ ).In group I/R,the hearts were perfused continuously for another 30 min.In groups D Ⅰ and D Ⅱ,the hearts were perfused with K-H solution containing dexmedetomidine 0.23,2.30 ng/ml for 20 min followed by 10 min washout before ischemia.All hearts were subjected to 30 min of global ischemia followed by 120 min of reperfusion with K-H solution.The activities of creatine kinase(CK) and lactate dehydrogenase(LDH) in coronary effluent were measured at the end of 10 min equilibration(balance),and at 5,30,60 and 120 min of reperfusion.Myocardial tissues were obtained at the end of reperfusion for determination of the activity of SOD and the content of MDA.Results Compared with group I/R,the CK and LDH activities in coronary effluent and MDA content in myocardium were significantly decreased,the SOD activity was significantly increased in groups D I and D Ⅱ ( P ＜ 0.05).Compared with group D Ⅰ,the CK and LDH activities in coronary effluent and MDA content in myocardium were significantly decreased,the SOD activity was significantly in group DⅡ ( P ＜ 0.05).Conclusion Dexmedetomidine preconditioning can attenuate myocardial I/R injury in a concentration-dependent manner in rats.

Objective To observe the effect of catgut embedding(CE) at "Shimen"(CV 5) on the endometrial receptivity,pinopodes expression of the endometrial surface and leukaemia inhibitory factor(LIF) immunoactivity during periimplantation period.Methods Thirty Kunming mice were randomly divided into control,CE of "Shimen"(CV 5,CE-CV 5) and medication groups(n=10/group).For mice of CE-CV 5 group,a piece of catgut was embedded into the subcutaneous tissue of "Shimen"(CV 5) on the day when the vagina-discharged epistom was found(pregnancy day 1,Pd 1).On Pd 4,mifepristone(0.1 mL,diluted in propylene glycol) was subcutaneously injected into CV 5 in rats of medication group.The expression of endometrial pinopodes(sampled on Pd 5) was observed by scanning electron microscopy.The immunoactivity of LIF of the endometrium was detected by immunohistochemistry.Results Compared with control group,the mean optical density(OD) values of LIF in CE-CV 5 and medication groups decreased significantly(P0.05).Electronic microscopic observation showed 1) abundant mature pinopodes on the endometrial surface,with a large number of well-stacked ecphyma in control group;2) fewer pinopodes and well-arranged smooth epithelial cells on the endometrial surface in catgut embedding group;and 3) no pinopodes found in the endometrium of medication group.Conclusion Catgut embedding at "Shimen"(CV 5) can suppress the establishment of the mouse endometrial receptivity,which is possibly related to its effect in inhibiting the expression of endometrial pinopodes and LIF.

Objectives To investigate the effect of bilateral arcuate artery suture hemostasis of corpus uteri (haemostasia) for postpartum hemorrhage due to uterine inertia during caesarean section,and to explore the change of blood vessels and blood flow of the uterus after surgery.Methods From May 2009 to Dec.2011,the 212 patients in No.202 People's Liberation Army Hospital received bilateral arcuate artery suture hemostasis of corpus uteri for postpartum hemorrhage due to uterine inertia during caesarean section.Among them,127 patients who failed to respond to conservative management and received haemostasia were defined as the ‘ haemostasia' group.23 patients who received the suture after they failed to respond to conservative management and other conventional surgical hemostasis were defined as the ‘ other +haemostasia' group.62 patients who received the suture simultaneously with conservative management were defined as the ‘ drug + haemostasia' group.The suture was done by the following steps:(1) The uterus should be exteriorised,and the fundus of uterus should be towards the head.(2)Transfix the anterior and posterior wall of corpus uteri with big blunt round needle and absorbable suture.The entry point was 2 cm above the uterine incision and 2 cm to lateral border of corpus uteri.The suture spanned the fundus of uterus,and was stretched tightly in front of the fundus,then tied knots were made.Bleeding volume,prompt hemostatic rate,effect rate,total effect rate and operation time were recorded.The resistance index (RI) of uterine artery,systolic/ diastolic blood pressure (S/D),the visualization ratio of uterine artery and the mean value of artery diameter were obtained through color Doppler ultrasonography and enhancement CT 6-12 months after the surgery.Results (1) In the ‘ drug + haemostasia' group,the bleeding volume was (532 ±28) ml.The operation time was (34 ± 3) min,and the prompt hemostatic rate was 97％.While the ‘ haemostasia' group had more bleeding volume,longer operation time and lower prompt hemostatic rate than the ‘ drug + haemostasia' group,with no statistically significant difference (P ＞ 0.05).In ‘ other + haemostasia' group,the bleeding volume was (1379 ± 95) ml.The operation time was (79 ± 15) min,and the prompt hemostatic rate was 78％.The differences were significant when compared to the other groups (P ＜ 0.01).There was no statistically significant difference on total effect rate among the three groups (P ＞ 0.05).(2) There was no statistically significant difference on the RI and S/D of bilateral uterine artery among all the groups 6-12 months after the surgery.(3)The visualization ratio of left uterine artery of the ‘ other + haemostasia' group was lower (87％) than the ‘ haemostasia' group (97％) and the ‘ drug +haemostasia' group (95％,P ＜ 0.05).There was no statistically significant difference between the ‘ haemostasia' group and the ‘ drug + haemostasia' group on the visualization ratio of bilateral uterine artery and the mean value of bilateral uterine artery diameter (P ＞ 0.05).Conclusions The bilateral arcuate artery suture hemostasis of corpus uteri is a simple,rapid,effective and safe method to control postpartum hemorrhage due to uterine inertia during caesarean section.The ovary and uterine blood flow are not affected after the surgery.

ObjectiveTo investigate the risk factors associated with macrovascular disease in patients with newly-diagnosed type 2 diabetes. MethodsAccording to arterial intima-media thickness(IMT)measured by color duplex ultrasonography,232 cases of newly-diagnosed type 2 diabetic patients were divided into two groups:one group were 95 cases with macrovascular disease(MD),and the other group were 137 cases without macrovascular disease (non-MD).Then various clinical data between the two groups were compared and the correlated risk factors for macrovascular disease were analyzed. Results (1)95 patients(40.9%)showed macrovascular disease in 232 patients.(2)Age,BMI,SI,systolic blood pressure,diastolic blood pressure,TC,LDL-C,CRP and 24h UmAlb were significantly higher in MD group compared with those in non-MD group(all P＜0.05);But ISI was significantly lower in MD group compared with that in non-MD group(P＜0.05).(3)Pearson correlation analysis showed that risk factors were old age,BMI,smoking,higher systolic blood pressure,higher diastolic blood pressure,TC,LDL-C,CRP and microalbuminuria. ConclusionMacrovascular disease was related to many factors.It was important to control some risk factors earlier for preventing the happening and progress of macrovascular disease.

To explore one-step method for the preparation of Ganoderma lucidum multicomponent microemulsion, according to the dissolution characteristics of triterpenes and polysaccharides in Ganoderma lucidum, formulation of the microemulsion was optimized. The optimal blank microemulsion was used as a solvent to sonicate the Ganoderma lucidum powder to prepare the multicomponent microemulsion, besides, its physicochemical properties were compared with the microemulsion made by conventional method. The results showed that the multicomponent microemulsion was characterized as (43.32 +/- 6.82) nm in size, 0.173 +/- 0.025 in polydispersity index (PDI) and -(3.98 +/- 0.82) mV in zeta potential. The contents of Ganoderma lucidum triterpenes and polysaccharides were (5.95 +/- 0.32) and (7.58 +/- 0.44) mg x mL(-1), respectively. Sonicating Ganoderma lucidum powder by blank microemulsion could prepare the multicomponent microemulsion. Compared with the conventional method, this method is simple and low cost, which is suitable for industrial production.

Objective To investigate the effects of azithromycin on airway remodeling and the expression of transforming growth factorβ1 (TGF-β1) in asthmatic mice.Methods BALB/c male mice were random divided into 3 groups:control group(A),asthma group (B),and azithromycin treated group (C),with 10 mice in each group.Bronchoalveolar lavage fluid was collected to count the number of white blood cells and eosinophilic granulocytes EOS.The morphological parameters of the bronchi were measured by computer image analysis and the pathologic changes of the bronchi and lung tissue were observed by HE staining.The expressions of TGF-β1 were detected by immunohistochemistry.Results The number of EOS in B group was significantly higher than that in control group(8.12 ±0.54 vs 0.70 ±0.40;8.12 ±0.54 vs 0.87 ±0.25,P ＜0.01).WAt and WAi and WAm in group C was significantly lower than that in group B (10.15 ±0.95 vs 15.36 ±0.85,4.16 ±0.32 vs 10.64 ± 1.03,3.77 ±0.15 vs 7.97 ±0.17,P ＜0.01)but higher than that in group A.The expression of TGF-β1 in group C was significantly lower than that in group B but higher than that in group A.TGF-β1 expression of lung tissue in C group was significantly correlated with EOS,(r =0.840,P ＜0.01) and WAt(r =0.735,P ＜0.01) and WAm (r =0.870,P ＜0.01).Conclusion Azithromycin inhibited airway remodeling in asthmatic mice,which might possibly be achieved through inhibiting the expression of TGF-β1.
