Objective To investigate influence of ureaplasma urealyticum(UU)infection on low genital tract during the pregnancy.The ureaplasma urealyticum was detected by the polymerase chain reaction(PCR) in women vaginal discharge. The patients were divided into infection group and control group.Results 624(25 68%) in 2430 cases of vaginal discharge had ureaplasma urealyticum infection. Infection rates of ureaplasma urealyticum was 24 53% in second trimester and 28 86% in third trimester respectively.184 cases (32 05%) of the premature rupture of membranes in infected group were significantly higher than 20 cases(22%) in control group. The UU infection incidence in small for gestation(SGA) age was increased in the infection group (45/574 vs 2/100)P

Objective To summarize the expreiences of management of triplet and quaternion pregnancy mothers and their in our hospital. Methods The clinical data of seven cases of multiple pregnancy (6 case of triplet and 1 case of quaternion) in our department from 1992 to 2003 were analyzed retrospectively. Results All seven patients had middle or severe anemia and hypoproteinemia in second and third trimester. The preterm sign happened in 2/3 cases in 32-36 gestation weeks. The patients were admitted in hospital in 27-34 gestation weeks because of obstetric complication. 6 triplet cases delivered during 35th-37th gestation weeks, except the quaternion one delivered at 33 gestation weeks. There were 22 newborns in those cases, the all babies Apgar's scores were above 9, the birth weights of all babies were above the 3th percent of Chinese singleton gestation and newborn estimated curves, and the birth weights of half babies were above the 10th percent position. Conclusion The key points for managing the multiple pregnancies, especially larger than 3 babies were the following ⑴All pregnant women had a good prenatal care. ⑵Pregnant women rested well, anemia must be corrected, and the adequate nutrition was supplied, especially in third trimester. ⑶Using ultrasound to determine the cervix length and evaluate the risk of preterm delivery, when the preterm delivery sign happened, the inhibiting drugs must be used cautiously and rationally. ⑷ After the antenatal dexamethasone therapy was applied around 36 gestation weeks, selective cesarean section was preferred to deliver the babies. If good prenatal care can be applied, a good outcome for triplets and quaternion can be achieved, close to that of same gestation weeks singleton.

Objective To investigate the correlation between KLF14 gene rs4731702 locus polymorphism and gestational diabe-tes mellitus (GDM) and relation between its different genotypes with BMI and insulin resistance.Methods This study adopted the case-control method.One hundred pregnant women of GDM (GDM group) and one hundred healthy pregnant women (normal con-trol group) were randomly selected as the research subjects and performed the physical examination ,biochemical indicators detec-tion.HOMA-IR and HOMA-β were calculated.The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was adopted.The genotyping of KLF14 gene rs4731702 locus in the two groups was performed.The genotypes and allele gene frequency were compared between the two groups and the GDM association analysis was conducted.Results The C alleles fre-quency and CC genotype frequency of KLF14 gene rs4731702 locus in the GDM group was significantly higher than that in the con-trol group ,the difference was statistically significant (P< 0.05).The patients with genotype CC in the GDM group had higher BMI ,FPG ,TG ,HbA1c and HOMA-IR as compared with those carrying genotype CT and TT ,the difference was statistically signif-icant(P<0.05).Also they had lower FINS ,HDL and HOMA-βas compared with carriers of genotype CT and TT ,the difference was statistically significant(P<0.05).The multivariate analysis showed that the genotype CC of KLF14 gene rs4731702 locus was closely related with GDM (P=0.005 ,RR=25.128).Conclusion The genotype CC of KLF14 gene rs4731702 locus plays a role in the pathogenesis process of GDM ,may be susceptibility genes for GDM ,which is also related to the abnormal lipid metabolism ,islet dysfunction and obesity.The polymorphism study of KLF14 gene rs4731702 locus helps to reveal the relation between lipid metabo-lism abnormality and insulin resistance with GDM onset.

Objective To determine the perinatal outcomes and its risk factors of fetuses prenatally diagnosed with the double bubble sign on ultrasound scanning.Methods The clinical data of 57 cases of fetal double bubble sign which was prenatally diagnosed by ultrasound in Xin Hua Hospital from January 1,2000 to December 31,2013 were retrospectively analyzed.The neonates survived not less than 42 days were as surviving group,and who survived lower than 42 days were as dead group.The t test,x2 test and Logistic regression were used for statistical analysis of the data.Results Of 57 fetuses with the double bubble sign,the incidence of polyhydramnios,intrauterine fetal death and associated anomalies was 88％ (50/57),4％ (2/57) and 23％ (13/57),respectively.Induced labor to terminate the pregnancy was occurred in eight cases,the other 49 cases had live births but ten neonates abandoned therapy.Thirty-nine live babies accepted surgical treatment with one dead,and the other 38 neonates survived not less than 42 days.The overall 42-day survival rate was 67％ (38/57) and the surgical survival rate was 97％ (38/39).Compared with surviving neonates,the neonates who died had lower gestational age [(35.8±3.0) vs (38.1 ± 1.9) weeks,t=2.859,P＜0.01] and birth weight [(2 229±567) vs (2 830±558) g,t=3.136,P＜0.01],and a higher incidence of prenatally diagnosed structural anomalies [3/11 vs 3％ (1/38),P＜0.05] and karyotype anomalies detected after birth [3/11 vs 3％ (1/38),P＜0.05].Logistic regression analysis showed that the fetuses with the double bubble sign and fetal growth restriction had a higher risk of complications (OR=9.893,95％CI:1.758 55.661,P=0.009).Conclusions Fetuses with double bubble sign have adverse outcome if they complicating preterm delivery,low birth weight,prenatally diagnosed structural anomalies and karyotype anomalies.

Objective To explore the prenatal diagnosis and factors influencing prognosis of congenital diaphragmatic hernia (CDH).Methods Fifty seven cases of CDH prenatally diagnosed by ultrasound in the Department of Obstetrics,Xinhua Hospital from January 1,2006 to March 31,2013 were retrospectively reviewed.Prognosis and risk factors were analyzed by ultrasound characteristics and newborn status.Statistical analysis was performed using t test,x2 test and Logistic regression.Results Forty-five (79％)of all cases were left-side CDH and the rest 12 (21％)were right-side.Fourteen fetuses were aborted.Thirty three were delivered and treated surgically,twenty-three infants survived after surgery and ten died,with an overall survival rate of 40％ (23/57).The other ten cases were delivered,but died of no treated surgically.The birth weight of the surviving neonates was heavier than that of those who died [(3 173 ±348) vs (2 846±568)g,t=2.238,P=0.033].The gcstational age at diagnosis of the aborted fetuses was younger than that of the surviving neonates [(24.0 ± 4.1) vs (30.0± 6.0) weeks,t=3.181,P=0.003].Twenty-one (91％,21/23) of the surviving neonates had a lung-to-head ratio (LHR) ≥ 1.4.A linear trend test showed a negative correlation between LHR and adverse outcome (x2=9.223,P=0.002) with a correlation coefficient-0.730 (P=0.000).LHR＜1.4 (OR=35.867,95％CI:1.861-691.341,P=0.018) and polyhydramnios (OR=9.285,95％CI:1.102-78.212,P=0.040) were risk factors for neonatal death.Right-side CDH (OR=0.158,95％CI:0.009-2.824,P=0.210),liver herniation into the thorax (OR=1.730,95％CI:0.144 20.707,P=0.665) and birth weight (OR=l.002,95％CI:0.999-1.005,P=0.135) were not risk factors.Conclusions The survival rate of CDH is still low.Gestational age on diagnosis,presence of polyhydramnios and LHR＜ 1.4 predict an adverse outcome.

Objective To discuss prenatal ultrasound features and fetal outcomes of meconium peritonitis.Methods This is a retrospective study of all cases of fetal meconium peritonitis (n=26) registered in the Department of Obstetrics,Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from April 1,2004 to December 31,2014.Prenatal ultrasound features,surgical findings and fetal outcomes were discussed.Variance analysis,Chi-square test or Fisher's exact test were applied for statistics.Results Among the 26 cases,25(96.2％) were diagnosed prenatally,24 (92.3％) underwent neonatal surgery,and 24 (92.3％) survived.Prenatal ultrasound findings included bowel dilatation (88.5％,23/26),intra-abdominal calcification (42.3％,11/26),fetal ascites (30.8％,8/26),intra-abdominal pseudocysts (15.4％,4/26) and polyhydramnios(50.0％,13/26).Surgical findings confirmed the diagnosis of meconium peritonitis was due to jejunal atresia[16.7％(4/24)],ileal atresia[75％(18/24)],and atresia of jejunal and ileal junction [8.3％(2/24)],respectively.However,no statistical significance was shown in the incidence of bowel dilatation,intra-abdominal calcification,fetal ascites,pseudocysts and polyhydramnios among the three groups of different etiology (all P＞0.05).Conclusions The prenatal ultrasound features of meconium peritonitis may vary a lot.But bowel dilatation combined with intra-abdominal calcification,fetal ascites or pseudocysts prompts the diagnosis of meconium peritonitis.Early surgical intervention in neonatal period could reduce the neonatal mortality remarkably,thus comprehensive and standardized perinatal management are necessary to improve fetal outcomes.

Objectives To explore the influence of standardized treatment and technical flow improvement on the diagnosis and treatment of congenital diaphragmatic hernia (CDH) after prenatal diagnosis. Methods The clinical data of neonates diagnosed with CDH who were hospitalized in neonatal intensive care unit from January 2005 to August 2016 was analyzed retrospectively. Based on the start time of standardized treatment implementation, 93 cases of CDH hospitalized from January 2010 to August 2016 were divided into the intervention group while 15 cases of CDH hospitalized from January 2005 to December 2009 were divided into the control group. The survival rate and complications of clinical outcomes between two groups were compared. Results There was no significant difference in sex, gestational age, birth weight, Apgar score, and CDH position between two groups (P >0.05). The total survival rate was 81.7％ in the intervention group and 53.3％ in the control group, and there was statistical difference (P<0.05). The difference of mechanical ventilation mode and pneumothorax rate between two groups also had statistical difference (P >0.05). The median operation time in the control group was 4.5 h and the intervention group was 49.5 h. The postoperative survival rate was 61.5％ in the control group and 90.5％ in the intervention group, and the differences between two groups were significant (P >0.05). The first blood gas analysis of deaths cases in both groups showed that there were significant differences in pH and PCO2 values (P >0.05). Conclusions Optimization of the clinical management during perioperative period can improve the survival rate of CDH and reduce complications. However, the dead cases in the intervention group had more severe pulmonary hypoplasia.

Objective To observe the application effect of bladder full-course management program based on the 5A model in patients after radical hysterectomy for cervical cancer. Methods A total of 94 patients undergoing radical hysterectomy for cervical cancer were selected and randomly divided into control group and study group, with 47 patients in each group. The control group received routine nursing intervention, while the study group received the bladder full-course management program based on the 5A model in addition to the routine nursing intervention. The indwelling catheter time, recovery of bladder function, quality of life scores, incidence of catheter-associated urinary tract infection, occurrence of lower urinary tract symptoms, and discharge satisfaction were compared between the two groups. Results The bladder function recovery rate was higher in the study group than in the control group, and the first catheter removal time and postoperative indwelling catheter time were shorter in the study group than in the control group(P < 0.05). The incidence of catheter-associated urinary tract infection was lower in the study group than that in the control group [2.13% (1/47) versus 14.89%(7/47), P < 0.05]. The incidence of lower urinary tract symptoms was lower in the study group than in the control group (P < 0.05). The scores of all dimensions of quality of life were higher in the study group than in the control group (P < 0.05). The discharge satisfaction rate was higher in the study group than that in the control group (95.74% versus 78.72%, P < 0.05). Conclusion The application of the bladder full-course management program based on the 5A model in the treatment of patients undergoing radical hysterectomy for cervical cancer can promote bladder function recovery, shorten the postoperative indwelling catheter time, improve quality of life, reduce the incidence of lower urinary tract symptoms and catheter-associated urinary tract infections, thereby enhancing patients' satisfaction.

Objective To analysis the causes and preventive measures of acquired pressure ulcers in hospitalized patients, and to provide evidences and references for strengthening hospital management of pressure ulcers.Methods We took a retrospective study to collect relevant information of 201 patients with hospital-acquired pressure ulcers from January 2012 to December 2014, and conducted a descriptive statistical analysis on the cause of the developed, high-risk departments and high-risk areas, then came up with preventive suggestions.Results The high incidence of 201 hospital-acquired pressure ulcers was oncology department, which accounted for 33.83%;the most common part was the sacrococcygeal region, which accounted for 59.2%;stage II was the most common stage of pressure ulcer, which accounted for 76. 12%; 64. 67% of the pressure ulcers happens within the first two weeks in hospital. Braden scoring less than 12 points that accounted for 58. 21%;anemia accounted for 72. 14%; hypoalbuminemia accounted for 75. 62%; forced postures caused by pain or hydrothorax and ascite accounted for 26.87%; medical equipment pressure accounted for 10.95%. The use of vacuum pad accounted for 87.56%;turning over once every 2 hours accounted for 41.79%. Skin nursing according to the guide accounted for 62. 19%; nutritional support through the mouth or vein accounted for 38.81%. Reporting to the nursing department timely after the occurrence accounted for 95.52%; found in ward rounds accounted for 1.99%; reported by patients or their families accounted for 1.49%; failure to report and found in the medical records accounted for 1.00%,the patient or family members to report accounted for 1.49%. Conclusions Cancer patients are high-risk groups of nosocomial pressure ulcers. The sacrococcygeal region is the high-risk area;stage II is the most common stage, and most of them happens within the first 2 weeks in hospital. Main reasons are hypoalbuminemia, anemia, forced postures, unable to turn over periodically, and the preventive care implementation is not enough. For cancer patients, preventive care is recommended, especially those patients with cancer pain, malnutrition and forced postures.

Objective:To understand the current situation of nurses in 52 hospitals in China on mastery of knowledge about skin injury in the elderly based on the background of mixed-mode homogenization training.Methods:Using the convenient sampling method, a total of 1 067 nurses from 52 hospitals in China were selected as the research objects in January 2021. A self-designed questionnaire on knowledge of skin injury in the elderly was used to investigate the nurses through the questionnaire star and univariate analysis was used to analyze the influencing factors. A total of 1 067 questionnaires were distributed and 1 067 valid questionnaires were recovered, and the effective recovery rate was 100%.Results:The knowledge scores of pressure injury, incontinence-associated dermatitis, skin tear and xerosis cutis among 1067 nurses were (95.66±7.37) , (95.65±9.15) , (91.37±15.45) and (87.67±15.91) , respectively. The results of univariate analysis showed that hospital grade was the influencing factor of nurses' knowledge score of pressure injury, skin tear and incontinence-associated dermatitis ( P<0.05) , educational background was the influencing factor of nurses' knowledge score of skin tear ( P<0.05) , professional title was the influencing factor of nurses' knowledge scores of pressure injury, incontinence-associated dermatitis and xerosis cutis ( P<0.05) . Conclusions:Hospitals at all levels need to strengthen the theoretical and practical knowledge training for nurses on skin xerosis and skin tear in the elderly, especially for nurses with primary titles and lower education in grassroots hospitals.
