Objective To investigate the analgesic efficacy of intravenous administration of lidocaine in patients following laparoscopic cholecystectomy. Methods Twenty-five ASA Ⅰ or Ⅱ patients, aged 30-55 yr,weighing 50-70 kg, scheduled for laparoscopic cholecystectomy, were enrolled in this study. Lidocaine 1.5 mg/kg was injected intravenously immediately before anesthesia. Anesthesia was induced with intravenous fentanyl 2 μg/kg, propofol 2 mg/kg and rocuronium 1 mg/kg and maintained with inhalation of isoflurane (end-tidal concentration 1.5%-2.0%) and intermittent iv boluses of rocuronium after tracheal intubation. Lidocaine was infused abdominal intravenously at a rate of 1.5mg·kg-1·h-1 form the end of ofperation to 24 h after operation. The degree of abdominal pain and shoulder pain was assessed with VAS score at 1, 6, 12 and 24 h after operation. The effective analgesia was defined as VAS score of ≤ 3. The adverse reactions were recorded. Results The effective analgesia rate was 100% within 24 h after operation. No adverse reactions occurred. Conclusion Intravenous administration of lidocaine exerts satisfactory analgesia in patients after laparoscopic cholecystectomy.

Objective To evaluate the effects of health education of house-to-house visit in malaria prevention and control in the border and minority areas. Methods A health education of house-to-house visit in malaria prevention and control was car-ried out,and baseline and follow up surveys were conducted by qualitative and quantitative methods to document the changes of local villagers’knowledge,attitudes and behaviors(KAP)of malaria prevention and control in 2 counties of Yunnan Province, and the results before and after the interventions were analyzed and compared. Results After the intervention,the cognition rates about malaria symptoms and signs,transmission mode,preventive measures and health-seeking behaviors were 99.3%, 98.9%,79.9%and 99.3%respectively in the local residents,and those were 39.2%,8.2%,47.0%and 49.9%respectively be-fore the intervention,and all the differences were statistically significant(P all<0.01). Conclusions KAP related to malaria among the targeting population has improved after the interventions and the house-to-house visit is an effective community-based health education approach.

Objective To evaluate an improved technique of vertical mammaplasty with purse string suture for correction of breast ptosis and its clinical application.Methods The adjustable markings of vertical mammaplasty was improved with an upper pedicle for the areola,and breast reduction was adapted with the lower part.The breast tissue was lifted and fixed on the second rib level to reshape the breast,which did not rely on the skin,with purse string suture for the lower half of vertical incision.32 patients with breast ptosis had been operated from May 2009 to February 2014.Results 32 cases were treated with vertical mammaplasty with short scar.The shape of the breasts was strengthen,without obvious scar,and follow-up results of patients were satisfied.Conclusions The vertical mammaplasty with short scar design is simple,operation is convenient,breast shape is plump,and postoperative long-term effect is great.This procedure can be used as one of the feasible operation for breast ptosis correction.

Objective To investigate mechanism involved in the differentiation of FBL-3 cells(eryth-roleukemia cells)induced by dendritic cells(DC). Methods To cultural the FBL-3 cells together with the DC supematant of different concentration for 72 hours,then we used the Wright's staining methed to record the ma-ture monocyte cell population, the transmission electron microscope to observe the ultramicrostructure, the flow eytoraetry to detect the expression rate of the surface molecular CD14. Results The Wright's staining methed, the transmission electron microscope and the flow cytometry all presented that after being induced by the super-natant of the DC ,the FBL-3 cells can partly differentiate into monocytes,inversion monocyte consistent with the personal characteristics. And the intensity of the DC supernatant was connected with interleukin-12. Conclusion The DC supernatant can induce the FBL-3 cells into monocytoid cell, the differentiated cells correspond to monocyte in macro-appearance,uhramicrostructure and phenotype. The competence of the DC supematant are partly concerned with interleukin-12.

Objective To investigate the effects of inhalation of different concentrations of carbon monoxide (CO) on brain death (BD)-induced lung injury in rats. Methods Thirty-two pathogen free adult male Wistar rats weighing 250-300 g were randomly divided into 4 groups ( n= 8 each): group Ⅰ sham operation (group S);group Ⅱ brain death (group BD) and group Ⅲ and Ⅳ BD + CO 0.025% and 0.050% (group C1, C2 ). The animals were anesthetized and tracheally intubated. Fogarty catheter was inserted into the skull. BD was induced by inflating the balloon slowly at 20 μl/min until apnea developed. The animals were then mechanically ventilated (VT 10 ml/kg, RR 50 bpm, PEEP 2 cm H2O) with 40% O2 in N2 . In group Ⅲ and Ⅳ CO 0.025% and 0.050%were added to the air mixture respectively. In group S the balloon was not inflated. BD was confirmed by apnea,dilated pupils and flat EEG. In group BD,C1 and C2, MAP was maintained at 80-120 mm Hg by norepinephrine infusion. The arterial blood gas analysis was performed before (baseline) and immediately after BD was confirmed (T1) and at 30, 60, 90 and 120 min (T2-5) of CO inhalation. The animals were then sacrificed. The plasma concentrations of IL-6 and TNF-α and the activity of myeloperoxidase (MPO) in the lungs were measured. The W/D lung weight ratio and lung injury score (LIS) were recorded. Results BD significantly decreased PaO2/FiO2, BE and pH while increased plasma IL-6 and TNF-α concentrations, MPO activity in the lungs, the W/D ratio and lung injury score as compared with group S. CO inhalation ameliorated the deleterious effects induced by BD. The antiinfiammatory effect of 0.050% CO was better than that of 0.025 % CO. Conclusion Inhalation of 0.025 % or 0.050% CO can ameliorate BD-induced lung injury in rats, but there is no significant difference in the efficacy.

ObjectiveTo investigate the effect of finasteride on hemorrhage in peri-operation of transurethral plasmakinetic enucleation of prostate (TUPKEP).Methods150 patients with benign prostatic hyperplasia (BPH) were randomly divided into 3 groups:control group without finasteride (n= 50),treatment groupl 1 with finasteride 5 mg daily for 7 days(n= 50) and treatment group 2 with finasteride 10 mg daily for 7 days(n= 50) before and after operation.All patients received TUPKEP and the data were recorded,including total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time after operation,amount of washing fluid after operation,and rebleeding rate within 3 months after operation.ResultsThe 150 patients successfully received TUPKEP.The total blood loss,amount of washing fluid during operation,operation time,blood loss per gram tissue,amount of washing fluid after operation,washing time after operation and rebleeding rate within 3 months after operation in treatment group 1 and 2 significantly reduced as compared with control group (P＜0.05).The blood loss per minute were (1.77±0.89) ml/min,(1.71±0.82) ml/min and (1.70±0.81) ml/min in 3 groups,respectively,and there were no significant differences among groups (P＞ 0.05).There were no significant differences between treatment group 1 and 2 in the total blood loss,operation time,amount of washing fluid during operation,blood loss of per gram tissue,blood loss per minute,washing time and amount of washing fluid after operation (P＞0.05).The rebleeding rate within 3 months after operation in treatment group 1 (8/35) and treatment group 2 (3/26) decreased as compared with control group (17/39) (x2= 3.544 and 7.523,P=0.016 and 0.025)and it was lower in treatment group 2 than in treatment group 1 (x2 = 1.293,P = 0.044).Conclusions The application of finasteride in peri-operation of TUPKEP can reduce hemorrhage.
