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 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.

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.

BACKGROUND:Vertebroplasty and kyphoplasty can effectively repair osteoporotic vertebral compression fractures, but postoperative change of stress in the fractured vertebrae and adjacent vertebrae can lead to new fractures. OBJECTIVE:To analyze the stress changes of the fractured and adjacent vertebrae with different bone cement injection volume by three-dimensional finite element method. METHODS:One healthy adult male volunteer was selected for lumbar spine CT scan. The acquired images were imported for three-dimensional reconstruction using Mimics. The three-dimensional model was smoothed, polished and denoised by Geomagic software, and then the solid mode was built under Workbench Ansys. The osteoporotic vertebral compression fracture model in L2-L4 segments was established after assignment. Bone cement of 1, 2, 4, 6 mL was injected into the L3 vertebrae respectively and distributed in the middle of the vertebrae as spherical shape. 500 N pre-load was applied on L2 surface with an additional moment of 50 N·m. The lower surface free degree of L4 was restrainted. The L2-L4 forward flexion, extension, right flexion and axial rotation on the right side were stimulated to compare the stress changes of fractured vertebrae and adjacent vertebrae before and after the bone cement injection with different volume. RESULTS AND CONCLUSION:The stresses of fractured and adjacent vertebrae after the bone cement injection were significantly increased; meanwhile, the stresses of fractured and adjacent vertebrae increased with the increase of bone cement injection volume, which may be one of the factors leading to the compression fractures of adjacent vertebrae.

Objective To compare the efficacy between autologous fat and hyaluronic acid in filling nasolabial grooves.Methods Sixty patients who wanted improvement of nasolabial grooves were involved in the study.They were randomly and equally classified into two groups:autologous fat injection group and hyaluronic acid injection group.Photographs were taken before,half a year,and one year after injection.The nasolabial grooves were also graded before,half a year,and one year after injection.The grade improvement was obtained after postoperative grade minus preoperative grade.If the grade improvement was more than 1 grade,the treatment was regarded as effective to evaluate the outcome between the two methods.Results The results of the two groups were tested by SPSS 13.0 software.The effects of the two methods were not significantly different after half a year of filling (P>0.05).The difference was significant one year after filling (P<0.05).In autologous fat injection,the patients had a long and magnificant swelling and redness around the nasolabial grooves;on the contrary,the patients who underwent hyaluronic acid had slight and short-time local reaction like swelling and redness.No other serious complications were found in both the groups.Conclusions The effects of the autologous fat and the hyaluronic acid are equal after half a year of filling.The autologous fat has a longer effect in one year.Both methods are safe and effective.Surgeons can select the method accordingly.
