Objective To explore the change of early stage coagulation function of newborn baby recovery from stifle and its clinical significance.Methods 120 asphyxial neonates were selected randomly as research subjects.The DD,PC,PLT,PT,APTT,TT and Fg were detected and compared with normal newborn baby.Results The statistical analysis showed that DD (t =17.65,P ＜ 0.01),PC (t =7.22,P ＜ 0.01),PLT (tsevere =10.95,P ＜ 0.01 ;tmild=4.12,P＜0.01),PT(tsevers =13.01,P＜0.01;tmild =8.09,P ＜0.01),APTT(tsevers =12.70,P ＜0.01 ;tmild =8.53,P ＜ 0.01),TT(tsevers =6.36,P ＜ 0.01 ; tmild =3.20,P ＜ 0.01) and Fg (t =21.24,P ＜ 0.01) of 120 patients had significant change,especially the severe stifle group had more significant change compared with mild stifle group.The treated babies relieved progressively and their indicators were back to normal.Conclusion There will be coagulation function disorder in early stage of newborn baby recovery from stifle.The degree of coagulation function disorder is related to the degree of stifle.

Objective To compare the anti-inflammatory effects between methotrexate(MTX) and Yangqixue Qufengshi Recipe(YQXQFSR) on mice arthritis induced by collagen II.Methods The model of rheumatoid arthritis was induced by using collagen II in C_(57)BL/6?DBA/1 mice.The rats with arthritis were treated with MTX or YQXQFSR respectively.The indexes such as the onset day of collagen induced arthritis(CIA),the level of CII-reactive antibodies and the pathological scores of CIA were assessed.Results The onset day of CIA and the level of CII-reactive antibodies were not influenced in the treatment of mice arthritis with MTX and YQXQFSR respectively.But MTX could alleviate the damage of cartilage [(1.60?1.51) vs(3.56?1.33) scores,P

[Objective] To investigate the role SPAG5 play in ovarian adenocarcinoma cell mitosis,Taxol sensitivity and ovarian high grade serous carcinoma patients' prognosis.[Methods] Transient knockdown of SPAG5 in SKOV3 cell were performed,and MTT assay and cell cycle flow cytometry assay were carried out.IHC staining of SPAG5 protein in 110 high grade serous carcinoma patients' tumor tissues were performed,and the expression were analyzed with clinical data and prognosis.Finally,SPAG5 were knocked down in OVCAR3 A2780 and SKOV3 cells followed by 0.5μM Taxol treatment,MTT assay were performed to detect cell viability.[Results] SPAG5 knockdown inhibited cell mitosis of ovarian adenocarcinoma cell SKOV3 by G2/M arrest.High grade serous carcinoma patients after neoadjuvant chemotherapy gained the expression of SPAG5.Patients without neoadjuvant chemotherapy with low SPAG5 expression have poor progress free survival,especially in early stage patients.Patients with low SPAG5 expression also have poorer overall survival,but the difference was not statistically significant.Furthermore,SPAG5 knockdown in OVCAR3 A2780 and SKOV3 cells reduced Taxol sensitivity.[Conclusion] SPAG5 regulated cell mitosis and promoted cell proliferation in ovarian adenocarcinoma cell lines.Expression of SPAG5 in patients' tumor tissues predicted patients' prognosis and Taxol sensitivity.As the results,individualized treatment of high grade serous carcinoma patients is necessary.

[Objective]To investigate the disturbance between Th17 and Treg cell balance in ovarian endometriosis patients.[Methods]Case-control study comparing 40 women with histo-pathologically confirmed ovarian endometriosis and with 40 control infertility women without visible endometriosis foci ,pelvic inflammations who were subjected to laparoscopic surgery during the same period. Peripheral blood,peritoneal fluid,ovarian ectopic endometrial tissue and eutopic endometrial tissue of ovarian endometriosis patients and controls were collected during surgery. T lymphocytes subpopulations in peripheral blood were analyzed by flow cytometry using specific monoclonal antibodies recognizing CD4+,CD25+and CD127-markers and CD3+,CD8-and IL-17A+markers. Then, IL-17,IL-22,IL-10and TGF-βconcentration in the serum and peritoneal fluid was determined using enzyme linked immunosorbent assay(ELISA). Also,Q-PCR was performed to verify Foxp3 mRNA and ROR-γt mRNA expression differences in eutopic and ectopic endometrial tissue.[Results]1.The percentage of CD4+CD25+CD127-Treg cells was significantly decreased in the peripheral blood ofwomen with ovarian endometriosis compared with control women. On the other hand ,the proportion of CD3+CD8-IL-17A+Th17 cells was significantly increased in the peripheral blood of women with endometriosis compared with control wom en. 2. Comparing with the controls ,the concentration of IL-17 and IL-22 was significantly higher in the serum of women with ovarian endometriosis ,and the levels of IL-10 and TGF-β were significantly lower in the serum of women with endometriosis. On the contrast ,in the peritoneal fluid of women with ovarian endometriosis ,the concentration of IL-17 and IL-22 were lower ,and the concentration of IL-10 and TGF-β were significantly higher than the controls. 3.Foxp3 mRNA expression level was significantly elevated in ectopic endometrial tissue of patients with ovarian endometriosis compared with eutopic endometrial tissue ,while the ROR-γt mRNA expression level of ectopic endometrial tissue was significantly decreased than eutopic endometrial tissue.[Conclusion]The present study verifies the imbalance of Th17/Treg in peripheral blood ,peritoneal fluid and endometrial tissue in ovarian endometriosis patients ,which implies the immune dysregulation and the disturbance of immunity homeostasis in the establishment and progression of endometriosis.

[Objective]To investigate the influence of different pre-pregnancy body mass index(BMI)on blood glucose and serum lipid and pregnancy outcome during pregnancy.[Methods]Clinical records of 1115 singleton pregnant women who underwent obstetric examination and delivered in the first affiliated hospital of Sun Yat-sen University between January 1,2013 and December 31,2013 were collected. The patients were divided into 3 groups based on pre-pregnancy BMI,underweight(G1):BMI<18.5 kg/m2, normal weight(G2):18.5 ~ 23.9 kg/m2 ,overweight (G3):≥ 24.0 kg/m2. The characteristics of blood glucose ,serum lipid and pregnancy outcome during pregnancy were analyzed and compared among groups.[Results](1)1 115 cases of pregnant women were Included in the study. The cases of G1 to G3 were 245,757 and 113.(2)With the increase of pre-pregnancy BMI,the blood glucoseof 75 oral glucose tolerance test(OGTT)fasting,1 h and glycosylated hemoglobin(HbA1c)was gradually rising(P < 0.05). The average blood glucose of 75 OGTT fasting among groups were(4.21 ± 0.34)(4.34 ± 0.35)(4.56 ± 0.50)mmol/L,75 OGTT 1 h were (7.51 ± 1.60),(7.83 ± 1.59),(8.83 ± 1.88)mmol/L,HbA1c were(4.81 ± 0.37)(4.90 ± 0.34)(5.03 ± 0.38)%,there was statistical difference among groups(P<0.05). The average FBG of G1 was lower than that of G2 and G3 group(P<0.05). The average blood glucose of 75 g OGTT 2 h of G3 was obviously higher than that of G1 and G2 group(P < 0.05). By Pearson analysis,FBG,75 g OGTT fasting ,1 h ,2 h ,HbA1c had significantly positive relationship with pre-pregnancy BMI(P < 0.05). The incidence of gestational diabetes of G3 group was higher than that of G1 and G2 group,but the incidence of gestational diabetes between G1 and G2 group had no obvious difference.(3)The triglycerides(TG)of G3 was obviously higher than that of G1 and G2 group(P<0.05), the total cholesterol(TC)and high density lipoprotein cholesterol(HDL-C)of G3 was lower than that of G1 and G2(P < 0.05). But There was no statistical difference about apolipoprotein A1(apoA1),B(apoB),E(apoE),Lp(a),Apo A1/Apo B among groups (P > 0.05). By Pearson analysis,TG had significantly positive relationship with pre-pregnancy BMI(P < 0.05),but TC,LDL-C, HDL-C had negative relationship with pre-pregnancy BMI(P<0.05).(4)With the increase of pre-pregnancy BMI,the weight and head circumference of the newborn was gradually rising(P < 0.05). The average weight of the newborn among groups were(3.03 ± 0.42),(3.18 ± 0.45),(3.30 ± 0.46)kg,the head circumference were(32.98 ± 1.59),(33.43 ± 1.64),(33.87 ± 1.60)cm,there was statistical difference among groups(P<0.05). The shoulder circumference of the newborn of G1 was obviously lower than that of G2 and G3 group(P<0.05). Pearson analysis showed that the weight,body length,head circumference,shoulder circumference of the newborn had positive relationship with pre-pregnancy BMI(P < 0.05).[Conclusion]With the increase of pre-pregnancy BMI, the blood glucose at each time point,serum lipid and growth index of the newborn was gradually rising. We suggest that overweight and obese women should lose weight before pregnancy.

Objective To determine the effects of adiponectin on high glucose induced BeWo cell proliferation in vitro. Methods BeWo cells were seeded in 96-well plates at the appropriate density. After treatments with high glucose (25 mmol/L), western blot analysis of cyclin D1 and a colorimetric assay (cell counting kit-8, CCK-8) were used to analyse BeWo cells′proliferation, and western blot was used to detect the expression of adiponectin. Moreover, we added adiponectin (20μg/ml) in the culture medium and three methods were utilized for cell proliferation analysis: CCK-8, cell cycle analysis (by flow cytometry) and proliferating cell nuclear antigen (PCNA) immunocytochemical staining. Results Compared to BeWo cells cultured by normal glucose and high mannitol, the proliferation of BeWo cells treated by high glucose increased (P<0.05). Compared with BeWo cells cultured by high mannitol, the expression of adiponectin in BeWo cells treated by high glucose decreased. After added adiponectin in the culture medium, the proliferation of BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose (0.770±0.050 versus 0.990±0.070, P<0.05);the proportion of G2+S phases of BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose [(40.7±2.1)%versus (44.9± 3.9)%, P<0.05];the rate of PCNA positive cell in BeWo cells treated by adiponectin+high glucose decreased than that of cells treated by high glucose [(28 ± 5)% versus (44 ± 5)%, P<0.05]. Conclusion Adiponectin could inhibit proliferation of high glucose induced BeWo cells in vitro.

Objective:To compare the maternal and fetal outcomes of women with cervical insufficiency (CI) undergoing McDonald cerclage (MC) and laparoscopic cervicoisthmic cerclage (LCC), so as to provide evidence for the selection of cerclage methods.Methods:A retrospective trial was carried out in the First Affiliated Hospital of Sun Yat-sen University from January 2010 to December 2020. A total of 221 women who underwent the prophylactic cerclage were divided into MC group ( n=54), LCC with MC history group ( n=28) and LCC without MC history group ( n=129) by the mode of operation and whether the pregnant women who underwent LCC had MC history. General clinical data, pregnancy complications and pregnancy outcomes were compared between the three groups. Results:(1) General clinical data: the proportion of women accepted cervical cerclage during pregnancy in MC group, LCC with MC history group and LCC without MC history group were 100.0% (54/54), 7.1% (2/28) and 27.1% (35/129), respectively ( P<0.001). The indications of the three groups showed statistical significance ( P=0.003), and the main indication was the history of abortion in the second and third trimester [75.9% (41/54) vs 89.3% (25/28) vs 84.5% (109/129)]. (2) Pregnancy complications: the incidence of abnormal fetal position [7.8% (4/51) vs 17.4% (4/23) vs 19.8% (24/121)], placenta accrete [5.9% (3/51) vs 13.0% (3/23) vs 11.6% (14/121)], uterine rupture [0 vs 4.3% (1/23) vs 5.8% (7/121)] in the MC group were all lower than those in LCC with MC history and LCC without MC history groups. However, there were no statistical significances (all P>0.05). Intrauterine inflammation or chorioamnionitis [15.7% (8/51) vs 0 vs 0.8% (1/121)] and premature rupture of membrane [23.5% (12/51) vs 4.3% (1/23) vs 0] were both significantly higher in MC group than those in LCC with MC history and LCC without MC history groups (all P<0.001). (3) Pregnancy outcomes: the cesarean section rate was significantly lower in MC group (41.2%, 21/51) than that in LCC with MC history group (100.0%, 23/23) and LCC without MC history group (100.0%, 121/121; P<0.001). MC group was associated with lower expenditure than LCC with MC history and LCC without MC history groups (12 169 vs 26 438 vs 27 783 yuan, P<0.001). The success rates of live birth cerclage did not differ significantly in MC (94.4%, 51/54), LCC with MC history (82.1%, 23/28) and LCC without MC history (93.8%, 121/129) groups ( χ2=5.649, P=0.059). There was no significant difference in neonatal intensive care unit occupancy, neonatal birth weight and neonatal asphyxia between the three groups (all P>0.05). Conclusions:Both LCC and MC are the treatment choice for women with CI, which may get similar liver birth. However, MC has the advantages of low cesarean section rate, economical and easy operation. Therefore, MC is recommended as the first choice for CI patients, and LCC is for women with failed MC.

The clinical practice teaching reform of pediatrics based on TBL combined with medical simulation teaching model was carried out. TBL teaching plan writing under the model of medical simulation teaching was researched. The principles, requirements, contents and procedures of compiling teaching plans were formed. Emphasis should be placed on medical simulation teaching, team cooperation, humanistic quality education and humanistic skills training. The purposes of the reform were to achieve standardized operation skills, improve clinical ability, ensure medical safety, and improve the quality of medical purposes, but still the reform need further improvement in the teaching practice.

Objective To investigate the morbidity, diagnostic profile and perinatal outcome of pregestational diabetes mellitus (PGDM) in 15 hospitals in Guangdong province. Methods A total of 41338 women delivered in the 15 hospitals during the 6 months,195 women with PGDM(PGDM group) and 195 women with normal glucose test result(control group)were recruited from these tertiary hospitals in Guangdong province from January 2016 to June 2016. The morbidity and diagnostic profile of PGDM were analyzed. The complications during pregnancy and perinatal outcomes were compared between the two groups. In the PGDM group, pregnancy outcomes were analyzed in women who used insulin treatment (n=91) and women who did not (n=104). Results (1)The incidence of PGDM was 0.472%(195/41338). Diabetes mellitus were diagnosed in 59 women (30.3%, 59/195) before pregnancy, and 136 women (69.7%,136/195) were diagnosed as PGDM after conceptions. Forty-six women (33.8%) were diagnosed by fasting glucose and glycohemoglobin (HbA1c) screening. (2) The maternal age, pre-pregnancy body mass index (BMI), prenatal BMI, percentage of family history of diabetes, incidence of macrosomia, concentration of low density lipoprotein were significantly higher in PGDM group than those in control group (all P<0.05). Women in PGDM group had significantly higher HbA1c concentration((6.3±1.3)% vs (5.2±0.4)%), fasting glucose [(6.3±2.3) vs (4.8±1.1) mmol/L], oral glucose tolerance test(OGTT)-1 h glucose((12.6±2.9) vs (7.1± 1.3) mmol/L)and OGTT-2 h glucose [(12.0±3.0) vs (6.4±1.0) mmol/L] than those in control group (P<0.01). (3)The morbidity of preterm births was significantly higher (11.3% vs 1.0%, P<0.01), and the gestational age at delivery in PGDM group was significantly smaller [(37.6±2.3) vs (39.2±1.2) weeks, P<0.01]. Cesarean delivery rate in the PGDM group (70.8% vs 29.7%) was significantly higher than the control group (P<0.01). There was significantly difference between PGDM group and control in the neonatal male/female ratio (98/97 vs 111/84, P=0.033). The neonatal birth weight in PGDM group was significantly higher((3159±700) vs (3451±423) g, P<0.01). And the incidence of neonatal hypoglycemia in the PGDM group was higher than the control group (7.7% vs 2.6%, P=0.036).(4)In the PGDM group, women who were treated with insulin had a smaller gestational age at delivery [(36.9±2.9) vs (37.9±2.5) weeks, P<0.01], and the neonates had a higher neonatal ICU(NICU)admission rate (24.2% vs 9.6% , P<0.01). Conclusions The morbidity of PGDM in the 15 hospitals in Guangdong province is 0.472%. The majority of PGDM was diagnosed during pregnancy; HbA1c and fasting glucose are reliable parameters for PGDM screening. Women with PGDM have obvious family history of diabetes and repeated pregnancy may accelerate the process of diabetes mellitus. Women with PGDM have higher risk for preterm delivery and neonatal hypoglycemia. Unsatisfied glucose control followed by insulin treatment may increase the need for NICU admission.

Objective To study the characteristics of fluid intake and central venous pressure (CVP) within 4 days after birth in very low birth weight (VLBW) premature infants complicated with bronchopulmonary dysplasia (BPD).Method From February 2015 to March 2019,VLBW preterm infants without serious complications were enrolled in two hospitals.Their CVP were measured every 4 ～ 6 hours after birth.They were assigned into BPD group and non-BPD group,and the fluid intake and CVP within 4 days after birth were compared between these two groups.Result A total of 45 VLBW preterm infants were included,including 17 in the BPD group and 28 in the non-BPD group.The fluid intake in the BPD group showed no significant difference with the non-BPD group within 4 days after birth (P ＞ 0.05).No significant correlation existed between the mean liquid intake and the mean CVP in 1 ～ 4 days after birth (r =0.093,P=0.542).From day1 to day4,the CVPs of the BPD group were (3.97 ± 0.68),(4.49 ± 0.75),(4.55 ± 0.66),(4.02 ± 1.05) cmH2O,and the non-BPD group were (3.66 ± 1.09),(3.96 ±0.76),(3.81 ± 0.69),(3.91 ± 0.65) cmH2O.The differences between the BPD group and the nonBPD group were statistically significant (P ＜ 0.05).The CVP of the BPD group was increasing from day 2 to day 3 (P ＜ 0.05).Conclusion VLBW premature infants complicated with BPD may have higher CVP at the early stage of life,which may not be related with the fluid intake.
