AIM:To investigate the effects of gonadotropin-releasing hormone ( GnRH) analogue on the growth of breast cancer cell lines MCF-7 and MDA-MB-231 in vitro and to explore the related mechanisms with PI 3K/Akt or ERK/MAPK pathways .METHODS: The proliferation of human breast cancer cell lines MCF-7 and MDA-MB-231 treatment with triptorelin was detected by MTT assay and the distribution of the cell cycle was determined by flow cytometry .The phosphorylation of the ERK 1/2 and Akt was evaluated by Western blotting .RESULTS:Triptorelin inhibited the prolifera-tion of MCF-7 cells at concentration of 10-5 mol/L after treated for 192 h or at concentration of 10 -4 mol/L after treated for 168 h and 192 h.Triptorelin inhibited the proliferation of MDA-MB-231 cells at concentration of 10 -4 mol/L after treated for 192 h (P<0.05).Treatment with triptorelin for 192 h at concentration of 10 -4 mol/L had no statistical significance effect on phosphorylation of ERK1/2 and Akt(P>0.05).CONCLUSION:Inhibitory effect of GnRH analogue triptorelin on human breast cancer cells is not just the connection with the down-regulation of pituitary hormone , but also a direct in-hibitory effect.The role may not be involved in the activation of ERK /MAPK and PI3K/Akt signaling pathways .

Objective:To investigate the feasibility and safety of fetal intravascular transfusion via the intrahepatic vein in the treatment of fetal anemia.Methods:This was a retrospective analysis of all fetuses requiring intrauterine transfusion (IUT) in the Shanghai First Maternity and Infant Hospital between January 2010 and December 2019. According to the different ways of IUT, they were divided into intrahepatic venous transfusion group and umbilical venous transfusion group, fetal outcomes and the incidence of procedure-related complications between the two groups were compared.Results:A total of 97 IUTs were performed on 48 fetuses. Among them, 16 cases were performed in the intrahepatic vein (31 transfusions), 32 cases were performed in the cord of the umbilical vein (66 transfusions).There were no significant differences between the two groups in age, labor history and the proportion of fetal hydrops before the first transfusion. In the intrahepatic venous transfusion group, the posterior placenta was 14/16, which was significantly higher than 78% (25/32) in the umbilical venous transfusion group ( P<0.01). The live-birth rates of the two groups were 13/16 and 75% (24/32). There was no significant difference between the two groups ( P>0.05). Before intrahepatic venous transfusion, the proportion of fetal hydrops was significantly higher than that of umbilical venous transfusion [55% (17/31) vs 24% (16/66), P<0.05]. Puncture success rate of intrahepatic venous transfusion and umbilical venous transfusion were both 100%. In the umbilical venous transfasion group, the incidence of needle slippage (5%, 3/66) and the abnormality of fetal heart rate (11%, 7/66) were higher than those in the intrahepatic venous transfasion group [0 and 3% (1/31)], but there were no significant differences between the two groups (all P>0.05). There were no cases of fetal loss within 24 hours, premature rupture of membranes, infection within 7 days and emergency cesarean section after IUT in both groups. Conclusions:Fetal intravascular transfusion via the intrahepatic vein is safe and feasible in the treatment of fetal anemia. But the requirements of puncture technique are relatively high, so it is recommended to be carried out in experienced fetal treatment center.

Objective To investigate the association between placental sharing,vascular anastomoses,cord insertion and perinatal outcome in uncomplicated monochorionic diamniotic (MCDA) placentas.Methods Between January 1,2012 and July 31,2013,60 uncomplicated (seclective fetal growth restriction,twin anemia-polycythemia sequence and twin-twin transfusion dyndrome) MCDA placentas were studied.These uncomplicated MCDA placentas were divided into the placenta equally shared group with placental territory discordance (PTD) ＜0.25 and the placenta unequally shared group with PTD ≥ 0.25.Angioarchitecture,cord insertion type and the distance between two cord insertions were compared using the Chi-square test and nonparametric test.Results Mean maternal age was (30.3±4.1) years.There were 39 cases (65％) in the placenta equally shared group and 21 (35％) in the placenta unequally shared group.Vascular anastomoses were observed in all placentas,arterioarterial anastomoses in 58 placentas (97％),and venovenous anastomoses in 17 placentas (28％).The overall diameter and the maximum diameter of arterioarterial anastomoses in the placenta equally shared group were (0.19±0.11) cm and (0.18±0.09) cm,respectively,and were lower than those in the placenta unequally shared group [(0.27±0.11) cm and (0.27±0.12) cm,respectively] (T were-2.39 and-2.94,P＜0.05,respectively).No significant differences in the number,the overall diameter and the maximum diameter of venovenous anastomoses were observed between the two groups (all P＞0.05).The incidence of cord velamentous insertion and cord velamentous insertion plus cord marginal insertion were 14％ (11/78) and 42％ (33/78),respectively,in the placenta equally shared group,and were similar to those in the placenta unequally shared group [14％ (6/42) and 33％ (14/42),x2 were 1.00 and 0.43,P＞0.05,respectively].The mean distance between two cord insertions was shorter in the placenta unequally shared group than in the placenta equally shared group [(14.3±6.3) cm vs (18.2±6.0) cm,T=2.37,P＜0.05].Conclusions In cases with unequally shared placenta,the distance between two cord insertions is shorter and the diameter of arterioarterial anastomoses is larger,which may compensate for their unequal placental territories,leading to no complications in these MCDA twin.

To assess the perinatal outcomes following selective feticide through radiofrequency ablation (RFA) in complex monochorionic pregnancies. Methods In this retrospective observational study, 34 cases of complex monochorionic pregnancies treated with RFA for selective feticide and delivered at the Shanghai First Maternity and Infant Hospital between January 1, 2012 and December 31, 2013, were included. Gestational age at RFA, the number of RFA cycles, maternal and fetal complications, gestational age at delivery, neonatal outcomes at 28 days after birth and neonatal development after birth were recorded. Fetal survival rate were defined as the number of survivors at 28 days after birth divided by the number of remaining fetuses after RFA. Factors affecting fetal survival rate were also analyzed. Statistical analysis was performed using Fisher's exact test. Results (1) The process for RFA:The gestatinal age for the procedure was (20.7±3.1) weeks(16+1-27+6 weeks). The successful rate of procedures was 100%(34/34) and the cycle number for RFA was 1-6 times. (2)Fetal complications and survival rate of remaining fetuses after RFA:there were six pregnant women suffering from premature rupture of membrane (PROM) before 28 weeks. Among those women, one had miscarriaged at 25 weeks, one chose to terminate at 26 weeks and the remaining four chose to continue the pregnancy. There were three remaining fetuses developing fetal severe anemia with hydrops after RFA. Two of them had fetal demises 2 days after the procedures and one chose to have termination. Another two cases with discordant fetal anomalies had fetal demises with unknown reasons one day after RFA. There were 27 remaining fetuses after RFA who survived until 28 days after birth. The mean gestational age at delivery was(36.4±4.1)weeks (26+4-40 weeks) and the mean birth weight was (2 913± 978) g (1 080-4 600 g). The overall fetal survival rate 28 days after birth was 79%(27/34). There were no abnormal findings in antenatal magnetic resonance imaging (MRI) four weeks after the procedure and no abnormal development of nervous system in the surviving neonates between 3 months old and 1.5 years old. (3) Factors affecting fetal survival rate :There were no significant differences identified in the rate of fetal severe anemia and fetal demise (2/15, 2/13 and 1/6), the rate of PROM before 28 weeks (1/15, 4/13 and 1/6) and survival rate of 28 days after birth (13/15, 10/13 and 4/6)among three groups with different gestational age (16+1-, 20- and 24-27+6 weeks) for RFA(all P>0.05). The indications for RFA included severe selective intrauterine growth restriction (50%, 17/34), discordant for fetal abnormalities(24%, 8/34) , twin reversed arterial perfusion sequence(18%, 6/34)and dichorionic or monochorionic triamniotic pregnancy (9%, 3/34). There were also no significant differences noted in the rate of fetal complications and fetal demise(3/17, 2/8, 0/6, 0/3), the rate of PROM before 28 weeks (3/17, 0/8, 2/6, 1/3)and survival rate of 28 days after birth among different groups (12/17, 6/8, 6/6, 3/3) with different indications for RFA(all P>0.05) . No significant differences observed in the rate of fetal complications and fetal demise(10% and 2/5)and the rate of PROM before 28 weeks (17%and 2/5)between two groups with different cycle numbers for RFA (<3 times and≥3 times, all P<0.05), while the group with cycle number ≥ 3 times had lower survival rate 28 days after birth than the group with cycle number<3 times for RFA (2/5 vs 86%, P<0.05). Conclusions RFA is one of effective and safe procedures for selective feticide in complex monochorionic pregnancies.

Objective To explore a new mode of prenatal diagnosis and counseling for congenital heart disease (CHD) by interdisciplinary cooperation and the value of Grading scale of fetal echocardiography in disease management.Methods The Grading scale of fetal echocardiography and a new integrative service mode of prenatal diagnosis and counseling for CHD with multidisciplinary team,including obstetric sonographers,obstetricians,pediatric cardiologists and geneticists,was established.For pregnant women referred to prenatal clinic in Shanghai First Maternity and Infant Hospital from January 1,2011 to December 31,2012,counseling about the diagnosis,severity,treatment options and long-term prognosis would be provided based on detailed fetal echocardiography and the grading scales.The significance of such mode in the prenatal management of CHD was analyzed and the rate of pregnancy termination was compared by Fisher exact test.Result According to the Grading scale of fetal echocardiography,there were four categories:Class Ⅰ,minor anomalies probably without treatment requried; Class Ⅱ,simple defects with normal life quality following after-born therapy; Class Ⅲ,complex anomalies with reasonable life quality after treatment; Class Ⅳ,severe malformation requiring multiple stage surgical repair or with very poor prognosis.There were a total of 54 pregnancies confirmed to have fetal cardiac anomalies by echocardiography,among which 27 were terminated.The average age of pregnant women was (29±3) years old,the average gestational week was 28.0±3.8.The abortion rate in women with the fetuses diagnosed as Class Ⅳ CHD was 17/19,higher than that in Class Ⅰ,Ⅱ and Ⅲ (3/15,3/10 and 4/10,Fisher exact test,all P＜0.01).In 19 Class Ⅳ cases,only two twin pregnant women continued their pregnancies because the other fetuses were healthy.Abortion was conducted in all 7 fetuses associated with extra-cardiac,chromosome anomaly or genetic syndrome.Conclusion The establishment of new integrated mode of prenatal diagnosis and counseling for CHD and Grading scale of fetal echocardiography in a multidisciplinary manner could provide comprehensive and authentic information and ethical advices for the families.

Objective: 16 S rDNA sequencing technology was used to analyze the changes of intestinal flora in rats with anti-tuberculosis drug-induced liver injury(ADLI) induced by rifampicin(RFP). Methods: Twenty-four male SD rats were randomly divided into control group(D0 group),RFP gavage group for 10 days(R10 group),and RFP gavage group for 28 days(R28 group).The fecal specimens of 4 rats in each group were selected by random number table method for 16 S rDNA sequencing. Results : Compared with the D0 group, the α diversity and β diversity of the R10 and R28 groups both changed(allP<0.05),the abundance ofBacteroidetesincreased at the phylum level, the abundance ofFirmicutesdecreased(allP<0.05),and the abundance ofUnclassified＿f＿Prevotellaceae,Blautia,Prevotellaceae＿NK3B31＿group,Erysipelotrichaceae＿uCG-003,Fournierella,increased at the genuslevel,Lactobacillus,Romboutsia,Ruminococcaceae＿uCG-014 decreased in abundance(allP<0.05). Conclusion In the process of RFP-induced ADLI in rats, the number of intestinal flora decreased, the structure and composition changed, the beneficial bacteria decreased, and the pathogenic bacteria increased, but the diversity of the flora remained unchanged.

Objective To evaluate the feasibility and clinical efficacy of intra-abdominal exposure instruments in laparoendoscopic single-port nephrectomy(LESS-N).Method From February 2012 to July 2016,61 cases of LESS-N were performed in our center.There were 34 males and 27 females with a mean age of (60.3 ± 9.4) years old (ranging 36-72 years old).There were thirty-nine cases of renal tumors and twenty two cases of nonfunctioning kidney.The patients were divided into two groups.Group A included 39 cases that underwent conventional LESS-N (22 radical nephrectomy/17 simple nephrectomy).Group B included 22 cases that underwent intra-abdominal exposure instruments assisted LESS-N (17 radical nephrectomy/5 simple nephrectomy).The perioperative and postoperative data were collected and analyzed retrospectively.Results All the procedures of these two groups were completed successfully.In Group A,four patients were added one 5 cm additional trocar and two patients were converted to open surgery.No additional trocars or conversion to open surgery were needed in Group B.For LESS radical nephrectomy,there were no significant differences of mean tumor diameter (5.7cm vs.5.4 cm,P =0.65) between two groups.The average operative time was (95.1 ± 43.9) min in Group B which was lower than that in Group A (127.4 ± 61.9) min (P ＜ 0.01).The mean renal vascular processing time was declined from (25.4 ± 10.1)rmin in Group A to (18.8 ± 8.9)min in Group B (P ＜ 0.05).The mean estimated blood loss was (128.6 ± 51.1) ml in Group A and (98.7 ±-57.6) ml in Group B (P ＜ 0.05).No severe intraoperative and postoperative complications occurred in both group.Conclusions Intra-abdominal exposure instruments are feasible and effective for LESS-N.This system may shorten the operation time,reduce the amount of bleeding and improve surgical accuracy.

The top 4 of drug resistant bacteria were dominated by Gram‐negative bacteria .The drug resistance rate of Klebsiella pneumoniae in RICU was higher than that in the respiratory outpatients department and wards(P<0 .05) ,the resistance rate in the respiratory outpatients department ,wards and RICU to commonly used antibacterial drugs was similar;the multiple drug resistance of ESBLs‐producing strains was obviously higher than that of non‐ESBLs‐producing strains (P<0 .05) .Pseudomonas aeruginosa maintained the higher antibacterial activity to quinolone ,aminoglucosides ,cefepime ,imipenem ,cefoperazone/sulbactam ,and piperacillin/tazobactam ,but the resistance rate in RICU was significantly higher that in the respiratory outpatient department and wards (P<0 .05);the drug resistance of Acinetobacter baumanii in the respiratory wards and RICU was higher than that in the respiratory out‐patient department ,the resistances to imipenem were 64 .6% and 70 .4% respectively .The resistance of MRSA to rifampin in RICU was higher than that in the respiratory outpatient department and wards(P<0 .05) .Conclusion The distribution constituent and drug‐resistance rates have obvious differences among the respiratory outpatient department ,wards and RICU .Except being familiar with the drug resitant bacterial distribution and drug resistance rate monitoring situation ,clinical doctors should grasp the drug re‐sistance situation of drug resistant bacteria among different areas in various departments of own unit in order to rationally and effec‐tively use antibacterial drugs .

Objective To evaluate the clinical efficacy of the local drug resistance spectrum antibiotics and foreign guideline in the treatment of patients with community acquired pneumonia(CAP). Methods A prospective,randomized,single blind,and positive drug parallel controlled design was used in the treatment. CAP patients with no underlying disease outpatients and inpatients<48 hours were selected as the research object. The patients in the trial group were given sensitive local drug resistance spectrum antibiotics: moxifloxacin,400 mg and 1 times a day. The patients in the control group were given azithromycin tablets(each 500 mg,once daily) promulgated by the 2007 version of the IDSA / ATS adult CAP guideline. Results There were 106 cases of CAP patients,of which 77 cases completed treatment,including 39 cases in the experimental group and 38 cases in the control group. There were significant differences in the clinical efficacy and bacterial clearance rate between the two groups,with the clinical efficacy of 89.7% and 68.4%(P < 0.01),the bacterial clearance rate of 87.9% and 54.5%(P < 0.05),respectively. Conclusion The clinical efficacy of drug resistant spectrum sensitive antibiotics in the treatment of CAP in Kunming was better than that of IDSA/ATS. Clinicians should pay attention to the characteristics and composition of resistance of common pathogenic bacteria in our country during the study and reference from foreign guideline,and adjust the therapeutic regimen according to the changes of the local drug resistance monitoring data rather than copy the recommended treatment plan by foreign countries.
