Field application of mosquito nets impregnated with Fendona (alphamethrin) was con-ducted in Jiangpu,Liuhe and Yizheng counties (city) during 1992 in order to control malaria and mosquito vector. Three groups were set for control,i.e. ,using mosquito nets impregnat-ed with deltamethrin, DDT spraying,and a group without preventive measures. The result showed that density of mosquito vector declined significantly after using of mosquito nets im-pregnated with Fendona. Mosquito density declined by 71. 58% ,the long-term efficiency last-ed more than 4 months,and local malaria incidence declined by 72. 73%. The effect of this measure was similar with that of using mosquito nets impregnated with deltamethrin, and was much better than that of DDT spraying. Since Fendona is a cheap,odourless,and effec-tive insecticide it is worthwhile to be recommended in malaria control program in the field.

Objective To investigate the preventive effect of fine management of hospital infection quality of obstetric rooming-in,in order to reduce the incidence of hospital infection.Methods Fine management run through each link of the hospital infection control from 2010,including a sound management system,strict implementation of the regulations for the operation and management of hand hygiene system,improvement of the building layout and work flow,strengthening the company staff and the ward environment management and monitoring,and make the management of hospital infection more standard.Results The obstetric rooming-in nosocomial infection rate decreased from 3.90％ in 2010 to 0.78％ in 2012.Fine management significantly reduced the incidence of nosocomial infection in our hospital.Conclusions The implementation of fine management in obstetric rooming-in is conducive to the effective control of nosocomial infection and promotion of maternal and child safety.

Pancreatic cancer is still a dismal disease.Angiogenesis is very important for the development of pancreatic cancer.Pancreatic stellate cells (PSCs) are the main source of extra-cellular matrix of pancreatic cancer and they provide advantageous microenvironment for cancer cells.PSC could promote the angiogenesis of pancreatic cancer both in vitro and in vivo.Further studies of the angiogenesis of pancreatic cancer are helpful in learning the characteristics of development and metastasis of pancreatic cancer,and provide new treatment method in the cellular and molecular levels.

A method for separation and determination of vitamin E from egg by reverse phase HPLC was introduced.The accuracy and precision of this method were much better than the ordinary method. Standrd deviation of retention time and peak area were 0.012 and 146.92, and the corresponding coefficient of variation was 0.22% and 0.44% respectively. The recovery rate was 100.6 ?3%. This method was suitable for measuring VE in egg, milk powder and cod-liver oil.

0.05).There was a negative correlation between PASP and the level of H2S in 3 groups at time points of pre-operation,1 h and 24 h post-operation (pre-operation,r=-0.66,P

Objective To explore the effect of Chitosan gel (Ⅲ) on the complications from Milligan-Morgan hemorrhoidectomy for treatment of severe mixed hemorrhoids.Methods Seventy-six patients with severe mixed hemorrhoids were randomly divided into treatment group and control group with 38 cases in each group. All patients from the two groups were treated with Milligan-Morgan hemorrhoidectomy. Then Chitosan gel (Ⅲ) was used in the treatment group. The two groups were compared in terms of curative effect, pain level, complications and hospital stay.Results There was no significant difference in the curative effect (P>0.05). But the scores on pain level, hemtochezia, infection and edema of the treatment group were all significantly lower than those of the control group (allP<0.05) and the hospital stay was significantly shorter than that of the control group (P<0.05).Conclusions In the treatment of severe mixed hemorrhoids by Milligan-Morgan hemorrhoidectomy, Chitosan gel (Ⅲ) is effective in relieving pains, reducing hemorrhage, edema and preventing infections and therefore shortens the hospital stay. In view of nursing, it is critical to perform mental care as well as close observations on complications.

Objective To improve the treatment effect of primary hepatic cancer (PHC). Methods Analysis of the influential factors on treatment effect of PHC in China, and propose the countermeasure. Results and Conclusions The main factors influencing the treatment effect of PHC in China are the followings: (1) Most patients with PHC of subclinical type failed to be diagnosed and treatment in time. (2) As a wrong idea PHC has been considered an “uncurable disease", so the treatment strategy is nagative. (3) Unsuitable choice of treatment resulted in some PHC unable to be resected. (4) Intraoperative massive bleeding due to unskill-operative techniques, increase the postoperative morbidity and mortality. (5) The manner of treatment is not positive for PHC patients with portal cancer thrombosis, bile duct cancer hteombosis and portal hyperlension. (6) Combined therapy can not be used or unsuitably used. The following things should be done in order to improve the treatment effect of PHC: (1) Strengthening improving the health-protective consciousness of people and regular examinaton of “high risk" population. (2) Renewing the professional knowledge in time to improve the level of diagnosis, treatment and operative techniques of medical personnel. (3) strengthening the basic medical research to make a break through in PHC treatment.

Object To study the apoptosis induced by sodium artesunate (SA) in human liver cancer cells and its molecular mechanism. Methods Induction of the apoptosis was analyzed by fluorescent microscope, transmission electron micrograph and flow lytometry based on drug treated BEL-7402. Expressions of p53, p21 and bc1-2 were determined by Western blot. Results The expression level of p53 and p21 had no change remarkbly, but the expression level of bc1-2 was reduced compared to that of the control group after the human liver cancer cells were treated by SA. Conclusion The apoptosis in human liver cancer cells (BEL-7402) may be induced by SA, the molecular mechanism of apoptosis may be p53-independent, that is no relative to p53 and p21. Otherwise, it is relative to bc1-2 down-regulation.

Layered anatomy is a both ancient and novel conception, which is derived from topographic anatomy.Topographic anatomy and phylembryogenesis are basic academic knowledges of layered anatomy.With the development of laparoscopic surgery and robotic surgery, less bleeding, more meticulous dissection, faster postoperative recovery and lower recurrence rate are required in surgical operation, because of which layered anatomy is mentioned and valued again.Organs in abdominal cavity are composed of different layered tissues,between them are loose connective tissues which are poor in vessels.Layered anatomy in surgical operation can avoid the en bloc dissection of organs, which not only reach total lesion dissection, but also avoid hurting surrounded normal tissues, showing the best surgical results.

Objective To investigate the characteristics of pathogenic bacteria and drug resistance and susceptible factors of pulmonary infection in patients with severe brain injury and to provide a guideline for the prevention and control of infection.Methods Bacteria culture results combined with clinical data of pulmonary infection in patients with severe brain injury were analyzed retrospectively in our hospital from Jan.2004 to Dec.2008.Results The patients with severe brain injury were often complicated by pulmonary infection.Gramnegative bacilli were main pathogenic bacteria leading to pulmonary infection ( 74.8% ),including pseudomonas aeruginosa ( 21.0% ),Escherichia coli ( 16.5% ),baumanii ( 13.6% ),pneumobacillus ( 7.7% ),enterobacter cloacae (6.3% ) and others.Thirty-nine Gram-positive bacilli were observed including Staphylococcus anreus,coagulase negative staphylococcus,enterococcus and others.There were 21 fungus infection observed.Conclusions Overall and systematically monitoring the condition of pathogenic bacteria distribution and drug resistance of pulmonary infection in patients with severe brain injury have important significance to select antibiotics and effectively prevent and control pulmonary infection.
