Objective To investigate effects of intrathecal injection of sufentanil combined with bupivacaine on postoperative analgesia and immunity function in elderly patients under lower extremity orthopaedic surgery.Methods Totally 60 elderly patients with ASA Ⅰ or Ⅲ under lower extremity orthopaedic surgery were randomly divided into two groups:bupivacaine and sufentanil group (each n =30).3 ml bupivacaine (2 ml 0.75％ bupivacaine plus 1 ml 0.9％ normal saline) were given in bupivacaine after successful spinal anesthesia and 3 ml sufentanil (1 ml 0.75 ％ bupivacaine plus 1 ml 0.9％ normal saline and 1 ml with 5 μg sufentanil) were used in sufentanil group respectively.The anesthetic feeling and block level before operation recovery time were recorded postoperation.Visual analogue scale (VAS) and adverse reaction were recorded at 1,6,12,24 and 48 h after surgery.Cellular and humoral immunity function were recorded at the following time points:T0,the day before surgery; T1,the day after surgery; T2,the first 5 postoperative days; T3,the first 10 postoperative days; T4,the first 15 postoperative days.Results The sensory and motor block levels in sufentanil group were T9～～T10 and T11～T12 respectively,which were higher than in bupivacaine (T7～T8 and T8～T10).The recovery time in sufentanil group was shorter than in the bupivacaine (P＜0.05).There were no significant differences in VAS scale between the two groups at any postoperative time points (P＜0.05).The incidence of skin pruritus was higher in sufentanil group (6 cases) than in bupivacaine (P＜0.05).There were significant differences in the indexes for the immune condition including CD3+,CD4+/CD3+,CD4/HLADR,CD8/HLADR,B-cell,NK-cell between time points of T2[(48.7±2.3)％,(33.4±1.8)％,(10.2±1.8)％,(0.75±0.07)％,(1.02±0.16)％,(3.12 ±0.19) ％,(2.53±0.14)％,respectively] and T0 in bupivacaine (P＜0.05).There were significant differences in the indexes for the immune condition including CD3+,CD4+/CD3+,CD4/HLADR,CD8/HLADR,B-cell,NK-cell at T2 between sufentanil group [(54.5 ± 2.4) ％,(36.3 ± 1.7) ％,(15.1±1.6)％,(1.32±0.11)％,(1.25±0.14)％,(4.96±0.25)％,(4.17±0.10)％,respectively] and bupivacaine (P＜0.05).Conclusions Intrathecal injection of 5 μg sufentanil combined with low concentration bupivacaine can be safely and effectively applied in elderly patients under lower extremity orthopaedic surgery,and can reduce local anesthetic concentration,shorten recovery time of anesthesia and accelerate the recovery of postoperative immunity function.

At present, the theory and experiment teaching of forensic toxicology are faced with difficulties such as lake of practical cases and toxic types, content being abstract and difficult to un-derstand. On that account, we collected and collated many typical cases from Public Security Bureau and our school's medico legal expertise center, and then a relatively systematic and complete teaching case base in forensic toxicology has been constructed, and will be supplement constantly, so as to pro-vide extensive teaching resources and improve the teaching quality of forensic toxicology.

To develop and validate a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for the quantification of epirubicin hydrochloride (EPI) in rat plasma, daunorubicin hydrochloride was used as internal standard. The plasma samples were deproteinated with methanol, and separation was performed on a reversed-phase CAPCELL PAK C18 column (3.0 mm x 50 mm, 3 microm). The mobile phase contained methanol-0.1% formic acid (80:20). Detection was carried out by multiple reaction monitoring on a HP1200-6410 QQQ LC/MS system. Different preparations of EPI solution, EPI-LIP (EPI-liposome) and EPI-LTSL (EPI-thermosensitive liposome) was administered in rats by i.v with the same dosage (12 mg kg(-1)). The pharmacokinetic model and parameters were fitted and calculated by the DAS ver2.0 software. The calibration curve was linear in the range of 0.01-50 microg mL(-1). The limit of quantification was 0.01 microg mL(-1). RSDs of intra- and interbatch precisions were all less than 11.9%. The average extract recovery was 89.3% and 92.1%, respectively. The pharmacokinetics of EPI in rats with all preparations were fitted to three compartments, which all fast distributed and slowly eliminated. The t1/2 alpha, t1/2 beta, t1/2 gamma, AUC(0-infinity), and MRT(0-infinity) of EPI-LTSL group were 7.5, 1.3, 12.6, 12.9, 3.7 times those of EPI solution group; and 1.6, 1.4, 12.3, 2.9, 2.6 times those of EPI-LIP group. Moreover, the CL of the latter two groups was about 13.4 times of the former EPI-LTSL group. EPI-LTSL can significantly improve AUC and prolong the circulation time of EPI in rat plasma.

Associations between "lipid-related" candidate genes, blood lipid concentrations and coronary artery disease (CHD) risk are not clear. We aimed to investigate the effect of three newly identified lipids loci from genome-wide association studies on CHD and blood lipid levels in Chinese Han population. The genotypes of SNPs at three newly identified lipid loci and blood lipids concentrations were examined in 1360 CHD patients and 1360 age- and sex-frequency matched controls from an unrelated Chinese Han population. Allele T of rs16996148 occurred less frequently in CHD patients with the odds ratio (OR) being 0.64 (95% CI 0.50 to 0.81), after adjusting for conventional risk factors and was associated with a 33% decreased CHD risk (P<0.01) comparing with the major allele G. Individuals with GT genotype had the lowest CHD risk. No associations were found between the polymorphisms of other two loci with CHD risk and all three SNPs had no effect on lipid profile in this population. SNP rs16996148 on chromosome 19p13 is significantly associated with lower risk for CHD in Chinese Han population. However, it remains unresolved why these lipid-related loci had significantly less effects than the correspondingly expected effects on blood lipids levels in this population.

Translational medicine has become the current focus in the field of medicine and health.To promote the development of translational medicine,the government should play multiple roles as planner,investor,coordinator,and supervisor,and to take its due responsibilities.

Objective To evaluate the contrast-enhanced 64-slice spiral CT(64-SCT) features and pathologic findings of coloniccancer comparatively.Methods 56 cases of colonic cancer underwent 64-SCT dynamic enhancement scans.All cases were classifiedaccording to 64-SCT features of arterial phase and then analysed pre-operatively with pathological comparation.Results There werecharacteristic manifestations on arterial phase of contrast-enhanced CT scan in all cases,the tumors with well differentiation appeared as slight-medial homongeneous enhancement in 23 cases,while undifferentiation tumors appeared as obviously inhomogeneous enhancement or layer-like enhancement in 33 cases.The tumors were classified according to their features on contrast-enhanced CT,the accuracy rate was 91.07%,the accuracy rate evaluated pre-operation was 92.86%.Conclusion 64-SCT dynamic scan has distinctive superiority in diagnosis and treatment of the colonic tumor.

Objective To investigate the nutrition status and quality of life(QOL)in the perioperative patients with laryngeal cancer and to analyze the effect of nutrition status on quality of life.Methods Sixty-six patients with laryngeal cancer were surveyed respectively by self-designed general situation questionnaire,nutritional risk srcreening 2002(NRS2002)and European organization for research and treatment of cancer quality of life core questionnaire(EORTC QLQ-C30).The impact of nutritional status on QOL was analyzed by the multiple linear regression analysis.Results The total score of nutritional risk of perioperative patients with laryngeal cancer was 3.53±1.51 and the incidence of nutritional risk was 28.79%.The nutrition status influenced on QOL, physiological function,cognitive function and pain area(P<0.05).Conclusion Nurses should assess the nutritional status of the patients and correct malnutrition without delay in order to improve the physical function and QOL of the patients.
