OBJECTIVE:To investigate the status quo and problems of application of parenteral nutrition in our hospital. METHODS:Cases of parenteral nutrition support(PN)from January to June in 2008 were reviewed and analyzed statistically. RESULTS:The problem of 637 patients treated with PN included indication,duration,prescription composition and incompatibility. CONCLUSION:The application of PN in our hospital is partly rational,nevertheless there are also some problems needed to be improved.

Objective:To summarize the drug repercussion data in outpatient pharmacy and analyze the reasons to provide sugges-tions for the improvement. Methods: The information was collected from the hospital information system ( HIS) during January 1, 2013 and December 31, 2015, including drug name, category, quantity, amount, reasons for drug repercussion and the other statisti-cal data. Results:During the three years, the number of prescription drugs, amount of money and varieties of drug repercussion were increased. The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients. The sum of drug repercussion was positively correlated with the drug price and the amount of drug repercussion. Conclusion:The op-tion simplicity for drug repercussion in HIS is the main reason for drug repercussion bythe other reasons. The occurrence of drug re-percussion should be intervened by such methods as gradually improving the HIS, establishing intervention measures, enhancing the professional quality of pharmacists and so on.

Objective To explore the relationships among mobile phone dependence and attachment,social support among adolescent students.Methods 900 students from two vocational colleges in Shandong province were recruited by stratified sampling.They were assessed with Experiences in Close Relationships Inventory (ECR) Chinese version,Social Support Rating Scale and Mobile Phone Addiction Tendency Questionnaire.Results There were no significant differences of adolescent students'mobile phone dependence on gender,child status,and native place.The score of middle vocational school students'mobile phone dependence (45.84 ± 12.64)was significantly higher than that of higher vocational college students (40.68 ± 9.72),and there was significant difference between them (P ＜ 0.01).Mobile dependence was significantly positively related with attachment anxiety (r =0.469,P ＜ 0.01),and was significantly negatively related with social support (r =0.149,P ＜ 0.01).Attachment anxiety and social support were the direct predictors of mobile phone dependence,and social support played the partial mediating role between attachment anxiety and mobile phone dependence.Conclusions Mobile phone dependence is a common phenomenon among adolescent students,and the middle vocational school students' mobile phone dependence is more serious than that of the higher vocational college students.There are close relationships between mobile phone and attachment,social support.Attachment anxiety is not only directly but also indirectly associated with mobile phone dependence by social support.

Objective To evaluate the short-term and long-term efficacy of conservative laparoscopic surgery combine with goserelin in treatment of severe ovarian endometriosis.Methods From January 2004 to December 2008,206 patients with severe ovarian endometriosis underwent laparoscopy surgery in Nanjing Drum Tower Hospital,Affiliated Nanjing University Medical School were enrolled in this retrospective study.According to the revised classification American Fertility Society (r-AFS), 123( 123/206,59.7％ ) cases were at stage Ⅲ and 83 ( 83/206,40.3％ ) patients were at stage Ⅳ.Among 138 cases presented pelvic pain.All the patients underwent laparoscopic cystectomy,of which 117 patients with childbearing preserving underwent hysteroscopy and hydrotubation examination,including 7 cases with bilateral salpingectomy,2 cases with bilateral tubal obstruction and 108 cases with normal reproduction.After surgery,all cases were administered by goserelin treatment at dose of 3.6 mg per 28 days for 3 to 6 months.At 1 to 5 years following up,pelvic pain,pregnancy and recurrence were observed,those factors associated with pregnancy rate and endometriosis recurrence were analyzed.Results (1)Pelvic pain:complete remission rate of pelvic pain was 76.1％ ( 105/138 ) at 1 to 5 years after surgery.(2) Pregnancy:total pregnancy rate was 70.4％ (76/108),spontaneous pregnancy rate was 68.8％ (66/96) and pregnant rate of in vitro fertilization and embryo transfer (IVF-ET) was 10/12.Pregnancy rate at 1 year was 57.3％( 55/96 ) and accounting for 83.3％ ( 55/66 ) in all pregnant womon.Live birth rates of spontaneous pregnant and IVF-ET were 86.4％ ( 57/66 ) and 9/10,respectively.( 3 ) Recurrence:the total recurrence rate was 8.3％ ( 17/206 ) at 1 to 5 years.The recurrence rates and the cumulative recurrence rates were 3.9％(8/206) and 3.9％ (8/206) at the first year after operation,2.0％ (3/149)and 6.7％ ( 10/149 )at the second year,1.0％ (1/99) and 8.0％ (8/99) at the third year,10.9％ (5/46)and 17.4％ (8/46) at the fourth year,0 and 2/18 at the fifth year,respectively.Conclusion It was suggested that conservative laparoscopic surgery combined with goserelin in treatment of stage Ⅲ or Ⅳ ovarian endometriosis could reduce the recurrence risk of severe ovarian endometriosis and improve the pregnant rate of endometriosisassociated infertility.

BACKGROUND: Previous studies have demonstrated that acidic fibroblast growth factor (aFGF) combined with partially deproteinized bone (PDPB) (aFGF/PDPB) well promotes avascularization in animals with early-stage avascular necrosis of the femoral head (ANFH), but the histological results remain unknown.OBJECTIVE: To observe the histological repairing effects of aFGF/PDPB on early-stage ANFH in rabbits. METHODS: New Zealand rabbits were established models of bilateral ANFH and were randomly divided into a blank group, a simple PDPB group, and an aFGF/PDPB group. PDPB and aFGF/PDPB bone were implanted into the PDPB and aFGF/PDPB group accordingly. The blank group did not receive any implantation. At 2, 4, and 8 weeks after surgery, all animals were sacrificed for histological examination to observe the osteogenesis by hematoxylin-eosin staining.RESULTS AND CONCLUSION: Defects were filled with granulation tissues and fibrous connective tissues, only a little osteoid tissue formed at the borderline in the blank group at the end of the 8th week. In the PDPB group, a little new bone and cavitas medullaris formed. At 8 weeks, lots of graft was absorbed and cavitas medullaris formed with more osteoplasts and myeloid cells in it. The osteogenesis in the aFGF/PDPB group was better than that of PDPB group in each time point. At 4 weeks, the transplanted cavity was filled with osteoid tissues, a lot of osteogenic precursor cells and osteoblasts could be seen. Plenty of micrangium was observed, and osteoid tissues began to rebuild. At 8 weeks, the graft was replaced by bone tissues, and cavitas medullaris were formed with lots of bone marrow cells in it. At the borderline of the bone trabecula, there were lots of osteoplast and little osteoclasts, which may play a role in bone remodeling. There were mature bone cells in bone lacuna. Results indicate that aFGF/PDPB has better repair effect on rabbit model of ANFH than that of simple PDPB.

Objective To study the effect of continuous positive airway pressure(CPAP) therapy for 56 clinical cases neonatal a-cute respiration prostration. Methods Based on the traditional treatment,CPAP assistant therapy were taken on 56 cases. The pressure of CAPA were adjusted according to the variations of clinical condition and blood gas value. Results After 6 - hour assistance of CPAP performance, the symptom of all cases had been abated, pa (O2) was increased, the normal CPAP applaying time was 28 hoours. The remarkable difference had been found compared to those in no CPAP practice(P

Castor(Ricinus communis L.),a high energy-stored and industrial raw-material plant species,is of great value in its application.Progresses in castor biotechnology were summarized in terms of tissue culture and genetic transformation.The results of studies on tissue culture indicated that application of TDZ(thiadiazuron) gave the maximum rate of shoot proliferation in various exogenous hormones when embryo axis was used as explant.On this ground,the in vitro regeneration system was established.The studies on castor genetic transformation showed that the Agrobaterium-mediated method was the most suitable one in different castor transformation methods.The hygromycin is suitable to selection of castor transfomants while castor embryo axis is insensitive to kanamycin.The possibilities of breeding of new castor varieties and improvement of castor production via biotechnology were also discussed.
