Objecttve To investigate the effects of snfentanil and ropivacaine used in labor combined spinalepidural analgesia(CSEA)and its influence on labor course and infants and its side effects.Methods 160 primiparas who chose deliver analgesia were randomly divided into two groups:group A intrathecal 5μg sufentanil plus saline up to 2.5ml,extradural 0.2μg/ml sufentanll plus 0.1% ropivacaine and saline up to 100 ml;group B extradural ropivacaine 1.5mg plus glucose 100g/L up to 2ml;group C have no analgesia.Then to investigate the effects of analgesia VAS scores,labor course duration,caesarean section rate,flooding volume,neonatal Apgar scores and its side effects.Results Compared with group C,the analgesia effects of group A and B were definitely(P＜0.05,P＜0.01);visual analogue score(VAS)at 5min,10min and 30min in group A were(3.4±1.2),(1.6 ±0.7)and(0.7 ±0.5)respectively,while in group B were(5.3±1.5),(4.3±1.8)and(3.1±1.7),which had significant difference in two groups(all P＜0.01);they all could reduce the first labor course duration,caesarean section rate,and there were no difference with group C(P＞0.05);and the flooding volume and neonatal Apgar scores had no differences(P＞0.05).Conclusion Sufentanil and ropivacaine combined used in CSEA has stronger effect and longer duration without prolonged labor coulee and poor side effects,which would be a more perfect analgesia worth clinical application in obstetrics.

The peroneal artery chimeric bone flap combined with chimeric flap of lateral femoral circumflex artery was applied in the repair of a case defects of both ulna and radius arteries combined with large extensive ring-like soft tissue defects of forearm in November, 2018, causing no blood supply to the hand. In the one-stage surgical procedure, anastomosis of the ulnar and radial arteries with the pedicle of the 2 flaps by Flow-through anastomosis were performed and the blood supply of the forearm and hand was restored. Six months after the surgery, the rotation functions of forearm, wrist joint and fingers were recovered. The patient was able to carry out daily activities and some of precision tasks.

Objective To explore the treatment effect of peripherally inserted central catheter (PICC) in parenteral nutrition of infants and observation and nursing of its complication.Methods Clinical data of 32 cases of infants who underwent parenteral nutrition through PICC were analyzed.The nursing experience and observation and handling of common nursing problems were summarized.Results 2 cases failed catheterization,the others succeeded,1 case through scalp,2 cases through axillary,27 cases through basilic vein.2 cases completed TPN treatment with a second try of PICC.The shortest indwelling time of PICC was 3 days,the longest was 34 days.Catheter blockage happened in 1 case,leakage in 1 case,and catheter-related infections in 1 case.Conclusions Difficulty exists in application of PICC in infants,but the complications were less.The tube can be retained for a long time,which conforms to higher intravenous nutrition requirement of infants,and this method possesses wide application perspective.

Objective To establish the triplex Taqman probes real-time RT-PCR method for simultaneously detecting of EV71,CA16 and EV.Methods Retrospective study.Specific primers and probes were designed based on conserved regions of EV71,CA16 and EV.The sensitivity,specificity and reproducibility were assessed by the optimized reaction system.A total of 176 throat swabs as the experimental group were collected from children with suspected hand foot mouth disease (HFMD),who admitted from April 2012 to July 2012 in Nanjing Children's Hospital affiliated to Nanjing Medical University.During this time,10 cases of healthy children,10 cases of outpatients with flu-like symptoms and 90 cases of inpatients in pneumology department of our hospital were recruited as control group,whose throat swabs were also collected.All of 286 samples were tested by the triplex Taqman probes real-time RT-PCR for simultaneously detecting EV71,CA16 and EV.SPSS13.0 was used to analyze the results.Results The sensitivities of the triplex Taqman probes real-time RT-PCR was 1.0 × 103 copies per milliliter for EV71,CA16 and EV.It showed 100％ specificity for 9 enterovirus and 3 non-enterovirus.Analysis with 1.0 × 103-1.0 × 105 copies per milliliter constructed plasmids demonstrated high reproducibility with coefficient of variation of 0.44％-1.04％ for EV71,0.38％-0.73％ for CA16,and 0.46％-0.90％ for EV.More over 176 samples collected from children with suspected HFMD were detected by triplex Taqman probes real-time RTPCR and real-time RT-PCR.The results showed 97.2％ (171/176)agreement and 0.94 Kappa value with high concordance.Conclusions The triplex Taqman probes real-time RT-PCR detecting EV71,CA16 and EV simultaneously has been established successfully.The assay,with high sensitivity and specificity,provide good basis for the rapid clinical diagnosis of EV71,CA16 and EV and open up broad prospects for clinical and relevant researches.

Objective To investigate the status of the cognition ,attitude and behavior related to hepatitis B among the college students in the business school ,and to provide the reference for making a reasonable and effective measures of prevention and health education .Methods A self‐designed questionnaire was used to surveyed 548 college students .Results The total awareness rate a‐bout the core information of hepatitis B prevention and treatment among the students was 81 .81% ,and rate of awareness of each hepatitis B question was between 54 .56% and 95 .44% .The total awareness rate of girls(82 .45% )was higher than boys(80 .69% ) (χ2 =5 .536 ,P=0 .019) .The total awareness rate of students in grade 3 and 4 (83 .13% )was higher than that of students in grade 1(79 .44% )(χ2 =17 .247 ,P=0 .000) .78 .83% student treated hepatitis B patients with the right mental attitude and students ac‐quired knowledge mainly from TV‐broadcast(75 .55% ) .Conclusion The college should strengthen health education on hepatitis B to improve students′awareness of hepatitis B ,eliminate hepatitis B discrimination and to improve the students′consciousness of prevention and treatment .

Objective To explore the incidence rate and the risk factors of deep vein thrombosis (DVT) in patients with traumatic fractures so as to provide references for prevention of DVT.Methods All of 534 Patients with fresh four extremities or pelvic fracture between January 2010 and December 2013 were involved in this study.The incidence of DVT under 5 risk factors including general state, injury type, fracture condition, operation and laboratory examination were analyzed.Each patient underwent three Doppler ultrasound exams in actions as the epidemiology diagnostic criterion for DVT.Results The total incidence rate of DVT in 534 patients was 11.99％.The univariate analysis showed that male patients with age≥60 years, BMI≥25 kg/m2, history of smoking, lack of exercises, history of diabetes, hypertension and coronary artery disease had higher incidence rate of DVT.In different injury types, the fall injury caused the highest incidence rate of DVT (45.71％).There were different DVT rates for different fracture sites, with the highest incidence rate of DVT for femur shaft fracture (20.69％).The incidence rate of DVT was 50.00％ for fractures of more than three parts, 15.29％ for fractures of two parts and only 3.98％ for sole part.The incidence rate of DVT for comminuted fractures was higher than others.The operation duration, massive transfusion during operation and general anesthesia were related with the increase of incidence of DVT.Positive ACA and enhancement of D-dimer, Fib and CRP were related with the increase of incidence of DVT.Conclusion The incidence of DVT in patients with traumatic fractures approaches a considerable level.It has relationships with age≥60 years, BMI≥25 kg/m2, history of smoking, fall injury, fracture of femoral shaft and hip, more than three parts of fractures, comminuted fractures, operation duration≥2 hours, largely blood transfused, massive transfusion during operation, general anesthesia, positive ACA, enhancement of D-dimer, Fib and CRP.The surgeons should recognize the importance to prevent DVT and PE in the traumatic patients.

Objective To study the respiratory function tests reference values of healthy children in China with impulse oscillometry(IOS).Methods The respiratory function tests reference values of 102 children were measured by using masterscreen IOS and analysed it.Results Impedance and airway resistance reference values decreased as age and body height increased step by step,at the same time capacitance decreased.The difference was significant while the predicted values compared to the measured data.Conclusion We shall use respiratory function tests reference values which are established by us,and the difference is significant compared with the foreign predicted(values.)
