Objective To study the effect of systematic prenatal education on the outcome of childbirth. Methods Pregnant women (200 cases) were randomly divided into 2 groups, 100 pregnant women who were willing to attend the maternity club to accept the systematic prenatal education were set as the experimental group, while 100 pregnant women who only accepted the regular prenatal health education as the control group. The experimental group not only received regular prenatal health education, but also had classes about prenatal gymnastics training exercise, the simulant delivery process, Lamaze pain relieving delivery, various postures of 3 delivery processes, the knowledge of husband assistance, the physical and psychological change and relevant coping method during gestation and postpartum, etc. The control group only accepted the regular prenatal health education, which was watching breastfecding VCD, having classes about the basic health knowledge and the physical process of pregnant period, delivery period, and puerperal period, the breasffecding knowledge, etc. Results The cesarean section rate and the total stage of labor of the experimental group was significantly less and shorter than that of the control group(P<0.05 and P<0.01). Conclusions The systematic prenatal e-ducation can improve pregnant women's knowledge of pregnancy and parturition, improve pregnant women's confidence of natural delivery, help to regulate nerve and the function of different organs, shorten the childbirth process, and reduce the cesarean section rate.

Objective To investigate the improved approach and bile duct approach of laparoscopic biliary tract exploration for the treatment of the elderly patients with common bile duct stones. Methods Ninety-two elderly patients with common bile duct stones were enrolled and randomly divided into the improved group and the conventional group ,with 46 cases in each group. The time of hemorrhage ,the time of common bile duct suture,the recovery time of gastrointestinal function,the time of hospitalization,body temperature,albumin and total bilirubin levels,complications and recurrence of stones were recorded and compared between the two groups. Results The time of hemorrhage,the time of common bile duct suture,the recovery time of gastrointestinal func-tion and the time of hospitalization in the improved group were lower than those in the conventional group(P<0.05, respectively). The body temperature of patients in the improved group was lower than that in the conventional group on 3 days after surgery(P<0.05). The overall incidence of postoperative complications in the improved group was lower than that in the conventional group (P < 0.05). No recurrence of stones was observed in both two groups. Conclusion The improved approach for laparoscopic common bile duct exploration surgery results in less bleed-ing,short common bile duct suture time,rapid postoperative recovery,less body temperature fluctuations and less complications,deserving popularization.

Objective To identify and classify six isolates of swine-originated Trichinella from China. Methods Five specific pairs of primers were synthesized based on DNA sequence of expansion segment V region and internal tran-scribed spacers (ITS1 and ITS2) of ribosomal DNA repeat from Trichinella. International reference strains of five Trich-inella species [Trichinella spiralis (T1), T. nativa (T2), T. britovi (T3), T. pseudospiralis (T4) and T. nelsoni(T7)] were used as control. Six swine Trichienlla isolates from Henan, Yunnan, Harbin, Tongjiang of Heilongjiang, Hubei and Tianjin were identified by multiplex PCR and its effecting factors of PCR amplification were observed. Results Electrophoresis results of multiplex PCR products of Trichinella larvae showed that the band (173 bp) of the six isolates was the same as T. spiralis(T1). The specific band (173 bp) was detected by multiplex PCR through amplification from issues of single T. spiralis larva, the larvae conserved in 80% ethanol for 6 months, the larvae stored in 10% formaldehyde, in 0.05% formaldehyde, 0.2% sodium azide or 0.05% merthiotate for 2 weeks,or fresh mouse muscle with larvae. Conclusion All the six swine Trichinella isolates are identified as T. spiralis (T1) by multiplex PCR.

Objective To investigate the risk factors associated to malnutrition in elderly inpatients for supplying clinical evidences for the prevention and therapy of malnutrition. Methods A one-to-one matched case-control study was used to investigate the risk factors associated to malnutrition in elderly inpatients over 60 years old. Results Eight-five pairs were included. Single factor analysis suggested that serum total protein. hemoglobin, serum total cholesterol, non auto -selective food, anorexia, dysphasia, confinement in the bed and infectious diseases might be associated with malnutrition in elderly inpaticnts (all P＜ 0.05 ). Logistic regression analysis demonstrated that serum total protein, hemoglobin, anorexia, dysphasia and confinement in the bed were the major risk factors (P＜0.05). Hosmer-Lemeshow test showed the predicable results and practical results had better similarity (x2 =4. 957, P= 0. 762). Receiver operation characteristic curve ( ROC curve) also revealed the area under curve of serum total protein and hemoglobin were 0 760 and 0.621(P=0.000 and P=0.006 respectiuely), therefore, 56.8 g/L of serum total protein and 108 g/L of hemoglobin might be appropriate reference points for evaluating the malnutrition. Conclusions Serum total protein, hemoglobin, anorexia, dysphasia and confinement in the bed may play crucial roles for malnutrition in elderly inpatients, the status of malnutrition will be improved if the reversible risk factors are amendable.
