Objective To evaluate the impact of epidural anesthesia with levobupivacaine combined with general anesthesia on colon surgery. Methods Sixty patients undergoing elective radical procedure for colon carcinoma were randomLy divided into four groups: saline group (group S), 0.125% levobupivacaine group (group L1), 0.25% levobupivacaine group (group L2), and 0.5% levobupivacaine group (group L3). Group S received normal saline of 10 mL epidurally and then infusion of 5 mL·h-1 until the procedure was finished; groups L1, L2, and L3 received levobupivacaine instead. Anesthetic induction was performed after epidural puncture. Mean blood pressure and heart rate were recorded at 8 time points including 5 min after entering into the operation room, 1 min after intubation, skin incision, abdominal exploration, 1 h after skin incision, completion of operation, extubation, and leaving PACU; meanwhile blood glucose and cortisol were detected, anesthesia time, time to PACU stay, bleeding, transfusion volume, adverse reaction, and doses of propofol, remifentanil, ephedrine, and fentanyl were noted. Results Time to PACU stay was longer in S group than in other 3 groups. Doses of remifentanil and fentanyl were larger in L1 group than in L2 group and L3 group. Ephedrine dose in L3 group was larger than in other 3 groups. Blood sugar in L1 group was higher than L2 group and L3 group. Cortisol in S group was higher than in other 3 group. Cortisol in L1 group was higher than in L3 group. The number of patients with hypotension was greater in L3 group than other 3 groups. Conclusions Continue epidural infusion of 0.25%levobupivacaine can reduce stress response and opioid uses, shorten PACU stay, whereas it does not increase use of ephedrine.

0.05). The amount of daily body weight gain in early minimal feeding group [(20.8?7.0)g/d] was higher than other groups (P0.05); The incidence of complications (apnea, vomit, abdominal distension, gastrorrhagia) was lower than in gastrogavage group (P0.05). Following all the patients when they were eighteen months old, there was respectively one cerebral palsy in the gastrogavage group and TPN group, and one mental retardation in TPN group. Conclusions Early minimal feeding and early sucking up could reduce the occurrence of feeding complications,shorten the length of hospitalization and reduce the incidence of sequelae in VLBWI.

Objective To improve the method of blood collection from external jugular vein in rats,so as to repeatedly obtain blood samples of high quality and to meet the special requirements of the experiment.Methods The experimental rats were anesthetized by intraperitoneal anesthesia,and the jugular vein was fully exposed with special fixed method.Whereafter,the blood samples were collected by disposable vacuum blood vessels.Results This method had little traumatic effect.The blood samples were collected from 60 rats at an interval of 14 days with 1.8 to 2.5 mL each time.The success rate was above 95%,and the normal activities of the rats were not apparently affected.This vacuum blood collection method guaranteed the quality of serum,and the veracity of blood detection and analysis were also significantly improved.Conclusion On the basis of the principle of animal welfare,the improved rat jugular vein blood collection method has the advantages of simple operation,less trauma,large blood collection,high blood sample quality aod so on,which can ensure the effect of the special experiment.

AIM:To compare the efficiency of fibrin glue to suture technique in pterygium surgery performed with limbal autograft under different methods of anesthesia.
METHODS: A prospective randomised clinical trial was carried out in 60 eyes of 55 patients operated for primary nasal pterygium, which were divided into two groups randomly: experimental group ( 30 eyes in 27 patients ) was under surface anesthesia ( oxybuprocaine ) and control group ( 30 eyes in 28 patients ) was under local anesthesia ( 20g/L lidocaine ). Autologous limbal graft taken from the superotemporal limbus was used to cover the sclera by a fibrin tissue adhesive after pterygium excision. Patients were followed up at least for 6mo. Time of operation, matching degree of graft and VAS score were mainly observed and recorded.
RESULTS: In experimental group the average surgery time was shorter (P=0. 008) and matching degree of graft ( 93%) was better than control group ( 83%) , the differences had statistical significance(P<0.05).
CONCLUSION: The surface anesthesia is enough when using fibrin glue for graft fixation in pterygium surgery, which will shorten surgery time and get better matching degree of graft.

Background and purpose: BRCA1 and BRCA2 mutation carriers have a high lifetime risk of developing breast and ovarian cancer. Through genetic counseling, mutation carriers can take the appropriate measures to reduce such cancer risk. At present, almost all related studies were conducted in Caucasian, while, the studies in Chinese population were rare. This study aimed to investigate the risk of breast cancer in BRCA1 and BRCA2 mutation carriers in Chinese Han population. Methods:Twenty unrelated families with BRCA1 or BRCA2 mutations were re-viewed. Kaplan-Meier analyses were used to estimate the cumulative risks of unilateral breast cancer and contralateral breast cancer for female BRCA1 and BRCA2 mutation carriers. Results:Breast cancer risk to 70 years (penetrance) was 67.2%(sx 0.100) for BRCA1 and 76.8%(sx 0.079) for BRCA2, respectively. Different from BRCA1 mutation carriers, the cumulative incidence of breast cancer in BRCA2 mutation carriers remained increasing after 70 years, reaching 93.1%at age 80. The 10-and 20-year risk for contralateral breast cancer was 19.4%(sx 0.089) and 50.3%(sx 0.155) for BRCA1/2 mutation carriers. Conclusion:BRCA1 and BRCA2 mutation carriers in Chinese Han population have a high risk of developing breast cancer. Thus, it has great clinical signiifcance to test mutations in BRCA1/2 genes in Chinese high-risk population.

OBJECTIVETo discuss the unsuccessful reasons and the preventive methods of the unsuccessful clinic cases.
METHODSThe retrospective analysis was carried on the 80 prosthesis in 70 patients from 1994 to 2001 which were suffered with unsuccessful results after the restoration of the metal crowns and bridges.
RESULTSThere were 68 teeth which had collapsed or broken. 20 teeth had the post loosing or shedding. Root breaking, food impaction, unharmony colors of porcelain and the changing color of gingival were 3, 3, 6 and 2 teeth.
CONCLUSIONIt is necessary to select suitable repairing materials and operate correctly for preventing the occurring of the unsuccessful results in the porcelain-fused-to-metal-crowns and bridges.

OBJECTIVETo explore risk factors of injection-related sharp injury and to provide safety injection guidance to healthcare takers.
METHODSA cross-sectional survey and 1:1 case-control study was used to study the epidemiological features and risk factors of sharp injuries among 3010 clinical nurses and nurse students from 13 hospitals in Guangzhou. Logistic multiple factor analysis was used.
RESULTSEighty-seven point five percent of nurses have suffered injuries at last once time. During the past month, 37.6% of the nurses have suffered injuries at least once time. The frequency of the injuries was 0.84 per person month. Through multiple logistic regression analysis, data showed that the risk factors leading to the sharp injuries in orders were: contacting the needle more frequently, subjectively thinking that the sharp injuries as unavoidable, the atmosphere in the nursing unit was not harmonious enough, recapping habit, carelessness at work, too many patients that not cooperating, breaking the ampule off without using carbasus, crowded and noisy working place, lack of acknowledge on prevention, lack of the awareness on how to avoiding the accident, having an initiative and creative personality etc.
CONCLUSIONThe results provided a foundation for the department of infection control in the hospital and sanitary administration department to constitute safety injection policies.
