Objective To observe the effect of pregnancy double loop cerclage for cervical incompetence. Methods 80 cases of cervical function incompetence according to the type of surgery were divided into two groups, 40 cases in each group,15 -20 weeks of surgery in pregnancy,the treatment group underwent double loop cerclage, the control group underwent McDonald single cerclage.The operation,postoperative cervical length and pregnancy outcome of the two groups were observed.Results There was no difference in operation time and blood loss between the two groups.The length of cervix in the treatment group was (4.63 ±0.52)cm,which was longer than (3.71 ± 0.82)cm of the control group(t =2.106,P <0.05).Pregnancy outcome:20 cases of the treatment group in term birth (50%),preterm birth in 18 cases (45%)(34 -37 weeks in 12 cases,28 -34 weeks in 6 cases),fetal survival in 36 cases (90%),less than 28 weeks pregnant inevitable abortion in 2 cases (5%),abortion did not survive.Average delivery gestational age was 35.2 weeks,and preoperative average abortion pregnant weeks contrast,treatment group delivery gestational weeks extended 13.5 weeks,the average weight of newborns was (3 200 ±200)g.The control group of full -term delivery was 14 cases (35%),premature in 20 cases (50%)(34 -37 weeks in 7 cases and 13 cases of 28 -34 weeks),fetal survival in 33 cases (82.5%),less than 28 weeks pregnant inevitable abortion in 4 cases (10%),abortion did not survive.Average delivery gestational age was 33.2 weeks,compared with the average abortion weeks before operation,the gestational age of the control group was extended by 11.5 weeks.The weight of newborn was (2 900 ±300)g.In the treatment group,the term labor rate,fetal survival rate,neonatal weight were higher than those of the control group,the difference was statistically significant (χ2 =7.83,P <0.05).Conclusion The second trimester cervical double cerclage can maintain effective cervical length,prolong gestational age,improve perinatal survival rate.

Objective To study the effect of astragaloside on proliferation and apoptosis in human keloid fibroblasts.Methods The human keloid fibroblast ceils were treated with different concentration of astragaloside(10、20、40 ng/mL).Cell proliferation was detected by MTT,the gene expreesion levels and protein levels of apoptosis-related proteins,survivin,p53 and Bcl-2.were determined by real-time PCR and Western blot,respectively.Results Comparecl with control group(treated with 0 ng/mL astragaloside),the absorbance values (A490 nm) of each concentration group were significantly reduced,which suggest that the proliferation of all keloid fibroblast were markably inhibited in a dose-dependent way (P＜0.05).The gene expreesion levels and protein levels of apoptosis-related proteins,survivin、Bcl-2 were largely suppressed and P53 werelargely promoted in a dose-dependent.Conclusion The keloid fibroblasts cells proliferation and apoptosis could be regulated by astragaloside.

Objective To explore the effect of suramin on the epithelial-mesenchymal transition (EMT) and the excretion of transforming growth factor-β1 (TGF-β1) in peritoneal mesothelial cells (PMCs) induced by high concentrations of glucose solution (GS).Methods Cultured PMCs were divided into three groups:(1) normal control group; (2) GS-treated group:cells were treated with 1.5％,2.5％,4.25％ GS for 12 h,24 h,48 h,respectively; (3) Suramin-treated group:PMCs cultured with 4.25％ GS were exposed to different doses of suramin (25,50,100 μmol/L) for 48 h.Expression levels of α-smooth muscle actin (α-SMA) and E-cadherin were detected by Western blotting and the concentration of TGF-β1 in the culture supernatant was determined by ELISA.Results Compared with normal control group,GS-treated PMCs exhibited a time-dependent increase in the expression of α-SMA,and decrease in the expression of E-cadherin.GS also stimulated PMCs to secrete TGF-β1.In the presence of suramin,GS-induced α-SMA expression and TGF-β1 production were reduced,E-cadherin expression was increased.Conclusions Suramin can inhibit high glucose-induced EMT of PMCs by down-regulating the expression of TGF-β1.Suramin may be a novel therapeutic agent for the treatment of peritoneal fibrosis.

Objective To observe the pregnancy by transvaginal double slit cervical pregnancy outcome after ligation,and evaluate its clinical application value.Methods The clinical data of 80 cases with cervical incompe-tence were analyzed.All patients had pregnant metaphase inevitable abortion history,the average abortion pregnant was 21.7 week.According to different treatment methods,80 cases were divided into two groups,treatment group (40 cases)in non pregnant women with silk thread woven tape by double vagina and cervix cerclage,another group of 40 cases in 15 -20 weeks of pregnancy by using polypropylene McDonald method with cerclage.The operation,preg-nancy cervical tube length and pregnancy outcome were observed.Results The average operation time and bleeding volume between the two groups had no statistically significant differences.The pregnancy cervical average length of the treatment group was 4.6(4.8 ±0.5)cm,which was significantly longer than 3.9(3.1 ±0.8)cm of the control group (t =2.732,P <0.05).In the treatment group,the full -term delivery rate,preterm delivery rate,mean gestational age at delivery were 55.0%(22 /40),40.0%(16 /40),35.8 weeks,the average abortion was extended 14.1 weeks com-pared with preoperation,fetal survival rate was 90.0%(36 /40),neonatal birth weight was (3 100.0 ±200.0)g;28 gestational weeks following the inevitable abortion rate was 2.5%(1 /40).In the control group,the term delivery rate was 35.0%(14 /40),the rate of premature birth was 50.0%(20 /40),and the rate of abortion was 15.0%(6 /40)in 28 weeks.Mean gestational age at delivery was 33.2 weeks,which was extended 11.5 weeks compared with preoperative average abortion,fetal survival rate was 85.0% (34 /40),neonatal body mass was (2 900.0 ±300.0)g. The term delivery rate,fetal survival rate and neonatal weight in the treatment group were higher than those in the con-trol group.Conclusion Pregnant by double vagina and cervix cerclage treatment cervical function can maintain preg-nancy,cervical length,prolong the time of pregnancy and improve the perinatal survival rate,simple operation,take out stitches convenient,it is worthy of clinical application.

Abstract?AIM: To observe the effect of acute angle closure glaucoma with cataract patients treated with glaucoma trabeculectomy combined two incision phacoemulsification and intraocular lens ( IOL ) implantation ( two incision triple surgery) .?METHODS: Patients admitted in our hospital during Jan.2013 to Jan.2016.The acute angle closure glaucoma with cataract patients in 40 cases ( 58 eyes ) were randomly divided into two groups:the observation group of 20 cases ( 29 eyes ) with two incision triple surgery treatment, and the control group of 20 cases ( 29 eyes ) with single incision triple after treatment.Visual acuity, intraocular pressure, bleb, corneal endothelial cell density, the area at 1mo before and after surgery, and postoperative complications of two groups were analyzed.?RESULTS: Postoperative visual acuity of two groups were significantly improved, but there was no significant difference between groups ( P >0.05 ); postoperative intraocular pressure, bleb formation rate of the observation group were 14.41 ±1.38mmHg, 90%, and the control group 14.40 ±1.40mmHg, 86% without statistical significance ( P>0.05 ), corneal endothelial cell density and area of observation group after 1mo were 1696.6±300. 8/mm2 , 540.8±71.6μm2 , and control group 1410.6±288.5/mm2 and 594.3 ±72.8μm2 with significant differences ( P<0.05).The incidence rate of compli-cation was 17%in the observation group, and 21%in control group (P>0.05).?CONCLUSION: For patients with acute angle closure glaucoma and cataract given two incision triple surgery and single incision triple surgery treatment can get good outcomes, but the effect of double incision on corneal endothelial cell injury is less.

Objective To study the influence of high-fluoride on thyroid function and brain damage. Methods Thirty-six Wistar rats were randondy divided, according to weight and gender into 3 groups(12 rats each), i.e. control group, high fluoride group, and high fluoride plus thyroid tablet treatment group. The rats were fed with normal tap water containing no more than 5 mg/L NaF and the tap water added 100,100 mg/L NaF, respectively. After 7 months of experiment, the rats in high fluoride plus thyroid tablet treatment group were given with 0.04% thyroid tablet( 1.8 ml·kg~(-1)·d~(-1)) by gastric perfusion for three weeks. The contents of TT_3 and TT_4 in serum were detected by radio-immunological assay; the histomorphology in thyroids and brains were observed under microscopy; and the protein level of NMDAR2B subunit of glutamate receptor in the hippocampal CA1 and CA3 was measured by immunohistochemistry. Results As compared to the values of TT_3 and TT_4 in serum of rats in control group[ (0.97 ± 0.15), (84.03 ± 12.45)nmol/L], TT_3 and TT_4 in high fluoride group were obviously lower [(0.24 ± 0.07), (15.16 ± 2.08)nmol/L, all P < 0.01]; while no changes in TT_3 and TT_4 were detected in high fluoride plus thyroid tablet treatment group[ (1.02 ± 0.19), (85.63 ± 9.55)nmol/L, all P < 0.05] as compared to controls, but higher than those in high fluoride group(all P < 0.01 ). The pathological changes including partial hyperplasy, arrangement disorder, atrophy, and decreased colloid of the thyroid follicular epithelial cells in high fluoride group were observed under microscopy. In high fluoride plus thyroid tablet treatment group, the degree of the thyroid cellular hyperplasy was relatively slight as compared to high fluoride group. The swelling and disarrangement of neurons in the hippocampus were observed in high fluoride group, whereas the changes of the neurons were not so obvious in high fluoride plus thyroid tablet treatment group. The grey values of NMDAR2B positive cells in the hippocampal CA1 and CA3 in high fluoride group(167.05 ± 7.31 ) were significantly increased as compared to controls (92.53 ± 9.67 ) or high fluoride plus thyroid tablet treatment group( 101.66 ± 12.21, all P < 0.01 ). Conclusions High fluoride can induce the decreased function and changed histomorphology in thyroid and result in pathological damages in the brains of rats. However, treated with thyroid tablet to those having damages induced by high fluoride, the thyroid function and morphology can be normal, and the brain damages can be alleviated. The results indicate that hypothyroidism caused by high fluoride might be an important participating factor in brain damages caused by fluorosis.

Objective To analyze the pregnancy outcome of laparoscopic cervical cerclage before pregnancy, discuss the clinical value of the treatment of cervical incompetence.Methods 40 cases with cervical insufficiency during 2012.1 -2016.3 before pregnancy underwent laparoscopic ligation.All patients had a history of abortion or premature birth,and the average gestational age was 23.7 weeks.Preoperative cervical length was less than 2.5cm. The operation condition and the pregnancy outcome after operation were observed.Results The average time of oper-ation was 35.6(40.2 ±10.4)min and the amount of bleeding was 10.3(15.7 ±3.2)mL.Postoperative pregnancy cervical average length was 3.61 (4.35 ±0.52)cm.Pregnancy outcome:37 weeks of gestation and above delivery 20 cases (50.0%).34 -37 weeks 16 cases (40.0%),28 -34 weeks in 3 cases,received cesarean section,the aver-age gestational was 35.6 weeks.Compared with the preoperative abortion,the gestational week of delivery was pro-longed by 12.1 weeks.Neonatal survival in 38 cases (95.0%),1 case of gestational 28 +3 weeks premature death. Neonatal birth weight was 2 800(3 079 ±500)g;1 case (2.5%)was difficult to avoid abortion at 23 weeks of gesta-tion.Conclusion Laparoscopic pre -pregnancy cervical cerclage suture in cervix mouth,postoperative can maintain effective cervical length,prolong gestational age,improve the pregnancy outcome,can be used as effective treatment for the pregnant cerclage failure or cervical length less than 2.5cm of cervical insufficiency patients.

Objective To observe the immunological effect of tumor cell vaccines to mouse hepatoma A(HepA) treated by Haematoxylin. Methods HepA cell was treated by 0.1% Haematoxylin and made into three vaccines: HepA vaccine with complete Freund' s adjuvant, HepA vaccine with incomplete Freund' s adjuvant; and HepA vaccine without any adjuvants. Five times of immunization were given the grouped mice with the above three vaccines, then active HepA cells (1×105 for each mouse) were inoculated by intraperitoneal injection to attack them; reckoning the mean survival time (MST) of the grouped mice, comparing the immunoprotective action of the three vaccines to the tmnor-bearing mice. Those mice only receiving normal saline (equal volume to the vaccine) were as a control group. Results MST of control group was (23.30±1.24) day; MST of mice receiving H22 vaccine with complete adjuvant was (43.90±15.20) day (P<0.02); MST of mice receiving H22 vaccine with incomplete adjuvant was (39.60±13.77) day (P<0.05); and MST of mice receiving HepA vaccine without any adjuvant was (38.40±12.54) day (P<0.05); As compared with the control group, the three treated groups showed a life-lengthening rate (LLR) 88.41%, 69.96 % and 64.81% respectively. Conclusion The vaccines treated by Haematoxylin give a marked immunoprotective action to those tumor-bearing mice. The HepA vaccine' s immunological effect is increased by the Freund' s adjuvant (complete or incomplete).

Objective To investigate the performance of MSCT in the diagnosis of metanephric adenoma.Methods The imaging data of 5 cases of metanephric adenoma confirmed by operation and pathology in our hospital were collected and analyzed retrospectively.The location, size, shape, density and enhancement of the lesion were further retrospectively analyzed.Results In the incorporated 5 cases of metanephric adenoma, the male to female ratio of cases was 1:4, all were unilateral, including 2 cases of the right kidney,3 cases of the left kidney,2 cases were located in the upper pole, 2 cases in the polar region, 1 case in the lower pole of the kidney.Maximum diameter of the metanephric adenoma ranged from 2.9 cm to 8.4 cm, with an average value of 4.8 cm.The shape of metanephric adenoma was classified into: round (3 cases) and oval (2 cases).On plain scanning slightly lower density was found in 2 cases, equidensity in 2 cases and slightly higher density in 1 case.Furthermore,1 case had small punctatel calcification in the edge of the lesion,1 case with renal papillary carcinoma.4 cases underwent plain and enhanced scanning,and 1 case plain scanning,in which slight density increase after intravenous enhancement was showed in 3 cases,moderate enhancement in 1 case,more uniform enhancement in 3 cases,uneven enhancement in 1 case,delayed enhancement in 4 cases.Conclusion The characteristic MSCT features of metanephric adenoma have a certain specificity.Preoperative correct understanding is helpful to guide the operation scheme.

Objective: To study the inhibitory effect of total alkaloids from lotus seed on human hepatoma HepG2 cells.Methods: The effect of total alkaloids from lotus seed on the growth of HepG2 cells was studied by CCK-8 kit.The apoptosis rate of HepG2 cells was detected by flow cytometry.Results: When the action time was the same, with the increase of drug concentration, the inhibitory rate of total alkaloids from lotus seed on HepG2 cells increased, in a dose-dependent manner.At 72 h, the half inhibitory concentration (IC50) of total alkaloids from lotus seed on HepG2 cells was 1.501 μg·ml-1.At the same concentration, the inhibitory rate of the total alkaloids from lotus seed on HepG2 cells increased with the extension of the action time.At 72 h, the inhibition rate of 10 μg·ml-1 total alkaloids from lotus seed reached 72%.After treated with the total alkaloids from lotus seed at different concentrations, the apoptosis rate of HepG2 cells significantly increased in a dose-dependent manner.Compared with the blank control group, the difference was statistically significant (P <0.05), and the apoptosis rate of HepG2 cells was 85.6% treated with 20 μg·ml-1 total alkaloids from lotus seed.Conclusion: The total alkaloids from lotus seed can induce cell apoptosis and inhibit the proliferation of human hepatoma HepG2 cells.
