In order to investigate the effects of simvastatin on secretion and mRNA expression of interleukin-6 (IL-6) and adiponectin in 3T3-L1 adipocytes, mouse 3T3-L1 adipocytes were stimulated with lipopolysaccharide (LPS). Production and mRNA expression of IL-6 and adiponectin in 3T3-L1 adipocytes were measured using enzyme-linked immunosorbent assay (ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR), respectively. The results showed that simvastatin could significantly suppress LPS-induced IL-6 production and mRNA expression in adipocytes (P<0.05), but increase the LPS-induced adiponectin secretion and mRNA expression in a dose-dependent manner (P<0.05). It was suggested that simvastatin could exert beneficial effects on prevention of obesity-induced metabolic changes in adipocytes.

Objective To study the feasibility of transumbilical single-incision laparoscopic surgery ( SILS) in the treatment of tubal pregnancy, as compared with conventional multi-port laparoscopic surgery. Methods Sixty-two patients diagnosed as tubal pregnancy undergoing laparoscopic surgery at this hospital between September 2013 and June 2014 were selected for investigation. There were 29 cases of transumbilical SILS ( SILS group) and 33 cases of conventional multi-port laparoscopic surgery ( MPLS group) . We retrospectively reviewed the medical records of all patients and analyzed the surgical outcomes, including operative time, blood loss, surgical complications and hospital stay. Results In both groups, all procedures were performed without failure.No conversion to open surgery or additional skin incision was needed.There were no differences between the SILS and MPLS groups in the operation time [(51.5 ±10.8) min vs.(47.3 ±9.4) min, t=1.637, P=0.107], the mean estimated blood loss [(15.5 ±10.5) ml vs.(18.4 ±12.2) ml, t=-0.996, P=0.323], the absolute decrease of hemoglobin from preoperative to postoperative [(14 ± 5) g/L vs.(13 ±4) g/L, t=0.874, P=0.386], the postoperative hospital stay [(3.5 ±0.9) d vs.(3.8 ±0.8) d, t=-1.390, P=0.170], and the incidence of postoperative fever (2 cases vs.3 cases, χ2 =0.000, P=1.000).Follow-up for 1-3 months ( mean, 1.8 months) in all the cases showed smooth recovery and no postoperative complications. Conclusion SILS is a feasible and safe approach in the treatment of tubal pregnancy.

Objective To detect anti-heterogeneous nuclear ribonucleoprotein A2 (hnRNP A2)/RA33 antibody by ELISA with the purified recombinant hnRNP A2 antigen. Methods The serum of 179 patients with RA, 141 patients with SLE, 97 patients with other diffused rheumatic diseases, 30 patients with seronegative spondyloarthropathies, 10 patients with osteoarthritis, 59 patients with arthralgia/arthritis and 40 controls were detected. In addition, clinical characters and laboratory indexes were compared to study the significance of anti-hnRNP A2/RA33 antibody in RA. Results The sensitivity and specificity of anti-hnRNP A2/RA33 antibody in RA were 36.9% and 87.1%. The positive rates of anti-hnRNP A2/RA33 antibody in SLE, other CTD, seronegative spondyloarthropathies and OA were 19.2%, 7.2%, 6.8% and 0. The positive rate of anti-hnRNP A2/RA33 antibody was 43.3% in early RA patients. Conclusion Detection of anti- hnRNP A2/RA33 antibody with purified recombinant hnRNP A2 antigen is a reliable method for early diagnosis of RA.

Objective To study cost-effectiveness of primary cerebral infarction patients. Methods The neural function of primary cerebral infarction patients was studied by the National Institutes of Health Stroke Scale (NIHSS) with rank test and multiple regression analysis. Results After treatment in hospitals of different grades, no obvious difference was detected in the NIHSS score, but difference was found in therapy cost and therapy time; the NIHSS score and therapy time of primary cerebral infarction patients in different attack positions were obviously different, but therapy cost had no significant statistical difference. The NIHSS score of primary cerebral infarction patients with different treatments was obviously different, but therapy cost and therapy time was not. Conclusions Patients are advised to choose grade hospitals in nearby cities for treatment. Clinician are expected to choose low-cost treatment plan to relieve patients' economic burden.

OBJECTIVE:To evaluate the merits and demerits of automatic oral drug dispensing mode as compared with traditional dispensing mode.METHODS:The medication data in our hospital after adoption of single dose administration system were collected and summarized analytically in respect of drug quality management.RESULTS:The automatic oral drug dispensing mode is superior to traditional dispensing mode.CONCLUSION:Under single dose administration system,the application of automatic oral drug dispensing mode is conductive to the improving of pharmaceutical care level.However,the problems existing in its clinical use remain to be further studied.

Objective:To explore the time course of memory recovery during post-traumatic amnesia after brain injury.Methods: A patient (WGS, aged 34) with lesions in the left temporal lobe was compared with four matched control subjects on various cognitive tests. These tests included Galveston Orientation and Amnesia test, Wechsler Memory Scale-Revised Test, Semantic Memory, and Remote Memory Test. WGS was tested at 20th days and 33rd days after the brain injury. Results: During the period of post-traumatic amnesia, marked recovery was observed for orientation, semantic memory and remote memory (especially the recent and the earlier items). While the recovery of learning for new knowledge was slow, learning curve of association of unrelated items was flat.Conclusion: The differential time courses for recovery of cognitive functions should be well considered in rehabilitative training after traumatic brain injury.
