0.05).The medical expenses of the Hysteroscopic Group was significantly lower than that of the Laparoscopic Group(t=-85.584,P=0.000).Conclusions As compared with laparoscopic conservative operation,hysteroscopic tubal catheterization with MTX injection is another simple,cost-effective,and minimally invasive alternative for early tubal pregnancy.

Objective To observe the repeat administration toxicity of Guanxinning Injection in rats.Methods Totally 120 rats (males and females) were randomly divided into vehicle control group and three Guanxinning Injection groups with different dosages (3.40,1.70,and 0.85 g/kg).Rats were administered with Guanxinning Injection by consecutive intravenous injection for 13 weeks.Besides the general conditions were observed,the related indexes were detected,such as body weight,the routine control of blood,hepatic function,renal function,the metabolism condition of lipids,the glycometabolism indexes,and histopathology analysis were determined at 13 weeks of treatments and 4 weeks after the withdrawal,respectively.Results Rats in the Guanxinning Injection group at 3.40,1.70 g/kg apperance shortness of breath,unsteady gait,lying motionless,and other symptoms.There was no obvious abnormal reaction in the 0.85 g/kg dose group.There were two male rats in the Guanxinning Injection group at 3.40 g/kg died at about week 4 of treatments,and there was no death in the 0.85 and 1.70 g/kg dose groups.Compared with vehicle control group,the related indexes of blood,blood biochemistry,organ relative quality,and histopathological showed no obvious abnormalities in Guanxinning Injection 0.85 and 1.70 g/kg group.The levels of urea nitrogen (BUN) and the relative weight of kidney in Guanxinning Injection 3.40 g/kg group were significantly higher than those in vehicle control group at 13 weeks.The change of these parameters regained to normal at 4 weeks after withdrawal and the rest of the detection index showed no obvious abnormality in 3.40 g/kg dase group.Conclusion Intravenous administration of Guanxinning Injection for 13 weeks at high dose could induce reversible damage to kidney.

Objective To evaluate the values of combined detection of soluble mesothelin related proteins (SMRP)and carbohydrate antigen 1 25 (CA1 25)in the diagnosis of malignant peritoneal mesothelioma.Methods 20 patients with malignant peritoneal mesothelioma were selected as the malignant group,50 patients with benign ovar-ian tumor were selected as the benign group,60 healthy women were selected as the control group.Enzyme -linked immunosorbent assay(ELISA)was adopted to detect serum SMRP levels and electrochemiluminescence immunifaction (ECLI)was adopted to detect serum CA1 25 levels.The SMRP,CA1 25 levels were compared among all groups,the sensitivity,specificity of SMRP and CA1 25 in the diagnosis of peritoneal malignant mesothelioma were analyzed. Results Serum levels of SMRP,CA1 25 in malignant group were (1 4.8 ±1 .6 )μg/L,(1 89.1 ±1 5.3 )μg/Lrespectively,which were significantly higher than those in the benign group[(3.9 ±0.9)μg/L,(28.6 ±4.2)μg/L] (t =27.40,49.61 0,all P <0.01 )and the control group[(2.8 ±0.7)μg/L,(1 6.9 ±3.8)μg/L](t =29.877, 53.334,all P <0.01 ).The sensitivities of SMRP,CA1 25 detection alone for malignant peritoneal mesothelioma diag-nosis were 65.0%,50%,respectively,while their specificities were 83.6%,79.1 %.The sensitivity and specificity of combined detection of SMRP and CA1 25 for malignant peritoneal mesothelioma were 95.0% and 93.6%.Conclusion SMRP has some value in the diagnosis of peritoneal malignant mesothelioma.SMRP combined with CA1 25 detection can markedly improve the diagnostic sensitivity and specificity for malignant peritoneal mesothelioma.

Objective:To investigatethe maternal and infant adverse outcomes of group B streptococcus (GBS) colonization during the late pregnancy.Methods:A total of 567 pregnant women who underwent obstetrics and gynecology examination in Yuyao People′s Hospital from December 2018 to June 2019 were selected for the study. Internal vaginal secretions of all the pregnant women were extracted from the lower 1/3 of the vagina for bacterial culture, and GBS culture and screening were performed on pregnant women. According to the results of GBS screening, pregnant women were divided into GBS negative group (8 cases) and GBS positive group (559 cases). The general condition and pregnancy outcomes of pregnant women were compared between the two groups, and the correlation between pregnancy outcomes and streptococcus colonization was analyzed.Results:There were no statistically significant differences in age, gestational weeks, number of births, number of pregnancies, history of abortion, residence area and ethnicity between the two groups ( P>0.05). The incidence of premature rupture of membranes and fetal distress in GBS positive group were higher than those in GBS negative group:5/8 vs. 7.69%(43/559), 3/8 vs. 5.01%(28/559), and the differences were statistically significant ( P<0.05). Spearman single factor correlation analysis showed that GBS colonization in pregnant women were positively correlated with premature rupture of membranes and fetal distress ( r = 0.632, 0.573, P<0.05). Conclusions:GBS colonization in late pregnancy is closely related to pregnancy outcomes, and strengthening GBS screening has great significance to reduce adverse pregnancy outcomes.

Objective:To investigate the effects of growth hormone combined with triptoreline acetate on growth and sex hormone in girls with central precocious puberty.Methods:Sixty-two girls with central precocious puberty who received treatment in Xin'an International Hospital from January 2017 to December 2019 were included in this study. They were randomly assigned to receive treatment with either triptorelin acetate (control group, n = 31) or triptorelin acetate plus growth hormone (observation group, n = 31) for 12 successive months. Before and after treatment, bone age difference/chronological age difference (△BA/△CA), body height, body weight, uterine and ovarian volume and sex hormone level were compared between the control and observation groups. Results:△BA/△CA in the observation group was significantly lower than that in the control group [(0.64 ± 0.17) vs. (0.95 ± 0.13), t = 8.065, P < 0.05). Body height and weight in the observation group were (127.32 ± 1.08) cm and (33.42 ± 2.37) kg, respectively, which were significantly higher than those in the control group [(126.34 ± 0.87) cm and (31.01 ± 2.15) kg, t = 3.934 and 4.193, both P < 0.05]. Uterine and ovarian volume in the observation group were (1.68 ± 0.29) cm 3 and (1.26 ± 0.18) cm 3, respectively, which were significantly lower than those in the control group [(2.41 ± 0.46) cm 3 and (1.83 ± 0.26) cm 3, t = 7.474 and 10.036, both P < 0.05). After treatment, there were no significant differences in serum estradiol and luteinizing hormone levels between the two groups (both P > 0.05). Conclusion:Growth hormone combined with triptoreline acetate has a good effect on central precocious puberty in girls because it can improve the growth and development of girls and reduce serum levels of estradiol and luteinizing hormone.

Assisted vaginal delivery (AVD) and cesarean section are two delivery methods used to terminate abnormal labor, which may cause physiological and psychological trauma to the parturient women, thus affecting their daily life and even next pregnancy. In recent years, scholars at home and abroad have paid more and more attention to "birth trauma", but its definition is still unclear. In clinical practice, more attention should be paid to the physiological and psychological trauma caused by AVD and cesarean section, but there is still a lack of specific trauma prediction and assessment tools, resulting in insufficient prevention and diagnosis of birth trauma. The authors reviewed the research progress in physiological and psychological trauma of parturient women induced by AVD and cesarean section in order to provide further reference and new ideas for the prevention and treatment of birth trauma.

Objective To discuss the safety and efficacy of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture.Methods There was an retrospective analysis on operation videos and clinical data for 16 participants of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture with the period from March in 2012 to September in 2015. And these were statistically analyzed including the operation time, intraoperative bleeding volume, postoperative drainage volume, removal time of drainage tube, admission time after operation and the incidence of postoperative complications of vesicoureteric reflux and stenosis.Results The operations of 16 participants were completed successfully without converting to open surgery. The operation time was 60 ~ 125 min (Mean time: 85 min); intraoperative bleeding volume was 20 ~ 50 ml (Mean volume: 32 ml); postoperative drainage volume was 60 ~ 400 ml (Mean volume: 106 ml); removal time of drainage tube was 3 ~ 6 d (Mean time: 4.2 d) and admission time after operation was 7 ~ 10 d (Mean time: 8.5 d). There was the follow-up with 6 ~ 18 months (Mean time: 12 months) for participants. No anastomotic stenosis was present. In addition, one participant was suffered from mild vesicoureteric relfux. And there was no aggravation during 18 months.Conclusions The inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture was safe and effective. It was found that the operation time was significantly shortened and the incidence of postoperative complications of vesicoureteric relfux and anastomotic stenosis was not increased. By contrast, the six-stitch suture could reduce the incidence of anastomotic stenosis.

Objective To investigate the indication and result of parental artery occlusion, embolization with coils, stents in treatment of the traumatic carotid artery pseudoaneurysm. Methods There were six patients with traumatic carotid artery pseudoaneurysm including three patients of cavernous pseudoaneurysm combined with carotid-cavernous fistula (CCF), two with simple traumatic carotid artery pseudoaneurysm and one with traumatic carotid artery pseudoaneurysm that was found after CCF embolization with detachable balloon. The treatment included balloon occlusion for CCF and traumatic carotid pseudoaneurysm in one patient, coil embolization in three and intenal carotid artery balloon occlusion in two. The Clinical manifestations, imaging data, choice of treatment, clinical efficacy, follow-up data and literatures were analyzed to discuss the indications for three treatments. Results There was no cerebral ischemia or surgically-related complication. No epistaxis occurred. The eyeball protrusion restoration was found in three patients and intracranial bruit vanishing in three. Vision was improved one patient after half a year follow-up. The pupils shrank in three patients during follow - up. Digital subtraction angiography (DSA) showed no recurrence of pseudoaneurysm. Conclusions Endovascular treatment is the preferred choice of treatment for traumatic carotid artery pseudoaneurysm. The occlusion or parent artery balloon occlusion can be used when the pseudoaneurysm is combined with CCF. Coil embolization can be used for shoes with narrow neck, stent technology combined with coil embolization for those with wide neck and the covered stent for the rock section of the internal carotid artery.

To investigate the relationship between the expression of RASSF1A protein and promoter hypermethylation of RASSF1A gene, RASSF1A protein expression was measured by Western blotting in 10 specimens of normal bladder tissues and 23 specimens of bladder transitional cell carcinoma (BTCC). The promoter methylation in BTCC and normal bladder tissues was detected by methylation-specific PCR (MSP). The results showed that the expression level of RASSF1A protein was significantly lower in BTCC tissues than that in normal bladder tissues. However, it was not correlated with its clinical stages and pathological grades. The frequency of promoter methylation of RASSF1A gene was higher in BTCC tissues than that in normal bladder tissues. In 14 patients with the aberrant promoter methylation, 13 showed loss or low expression of RASSF1A protein. It is concluded that RASSF1A gene promoter methylation may contribute to the low level or loss of RASSF1A protein expression, the inactivation of RASSF1A gene and the genesis of BTCC. But, it may bear no correlation with its clinical stages and pathological grades.

Pinch-3 protein is an important constituent of cell membranes, which directly affects the cell morphology and mechanical properties. We observed and compared the change of morphology and cell traction force of glomerular podocytes before and after Pinch-3 gene inhibition by gene interference technology in this experiment. We found that a number of pores appeared on the cell surface, and the cell projected area were increased at the same time, with an approximate average about an increase of 40% after Pinch-3 gene inhibition. The results showed that the cell traction force of glomerular podocytes was significantly reduced, with an approximate average decrease of 40%, the maximum value of the cell traction force was reduced and the distribution of cell traction force became dispersive. All this suggested that after Pinch-3 gene inhibition, some pores created on the cell surface influenced the physical properties of glomerular podocytes and then affected the cell projected area and influenced the formation and distribution of cell traction force of the glomerular podocytes as well.
