Objective To compare the effect of ropivacaine mesylate with ropivacaine HC1 for patient-controlled epidural analgesia ( PCEA) after transabdominal hysterectomy. Methods Forty-four ASA 1 or D patients aged 18-65 yrs weighing 45-80 kg undergoing elective abdominal hysterectomy performed under epidural anesthesia with either 0.75% ropivacaine HO (control group, n = 22) or 0.894% ropivacaine mesylate (study group, n= 22) . An epidural catheter was placed at L2,3 and advanced 3 cm into the epidural space. After operation PCEA was performed with 0.2% ropivacaine HCl ( control group) or 0.237 % ropivacaine mesylate (study group) respectively. Postoperative pain was assessed using VAS (0-10, 0 = no pain, 10 = worst pain) . Motor blockade was assessed using the Bromage scoring system. The patients' satisfaction level and adverse events were also recorded. Results There were no significant differences in VAS scores, motor blockade and incidence of adverse events between the two groups. The number of effective pressing in study group was significantly less than that in control group. Starting from 4h after operation the drug consumption in study group was significantly less than that in control group. Conclusion 0.237 % ropivacaine mesylate can be used for PCEA after transabdominal hysterectomy as safely as 0.2% ropivacaine HCl.

Objective To investigate the clinical appliance value of plantar pressure measurement in hemiplegic patients with acute cerebral infarction(ACI).Methods Plantar pressure was measurered and recorded by the means of Germany-made Zebris in 21 hemiplegic patients with ACI before and 30 d after treatment.Results Although plantar pressure on foot of the paralysed side was found remarkably decreased compared to that of the contralateral side before treatment(all P

Objective To analyze the expression profile of long non-coding RNA (lncRNA) in the lipopolysaecharide (LPS)-induced inflammation of monocyte-derived macrophages.Methods Peripheral blood mononuclear cells were derived from healthy donor and induced into macrophages. The macrophages were divided into blank control group and LPS (1 mg/L) stimulated 12 hours group. Culture supernatants and cell pellets were harvested in each group, enzyme linked immunosorbent assay (ELISA) was used to assay the production changes of interleukins (IL-1β and IL-6), and tumor necrosis factor-α (TNF-α) in the supernatant. The technique of lncRNA microarray was used to test the lncRNA expression profile in LPS-induced inflammation of macrophages and control macrophages. The raw data of lncRNA were pretreated for normalization. Five lncRNA expressions were validated by real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Furthermore, qRT-PCR was used to detect the expression of NR_028034 in macrophages after LPS-induced inflammation.Results ① The contents of IL-1β (ng/L:562.93±61.17 vs. 59.74±15.68), IL-6 (ng/L: 702.46±92.31 vs. 71.66±18.25) and TNF-α (ng/L: 794.50±63.89 vs. 85.12±22.07) in the LPS group were significantly higher than those in the blank control group (allP < 0.01). These results indicated that the inflammatory model of human macrophages was constructed successfully. ② Compared with blank control group, and 1479 lncRNA which have more than 2 folds variation and significant difference (P < 0.05) by statistical analysis was defined as lncRNA with differential expression. Among these lncRNA, LPS group showed 953 up- regulated and 526 down- regulated genes by 2 folds and 49 up- regulated and 35 down- regulated genes by 5 folds. ③ qRT-PCR results were generally consistent with the microarray data. ④ The expression of NR_028034 was increased by (4.41±0.65), (11.56±2.04), (18.58±1.36) folds compared with blank control group at 3, 6, 12 hours after LPS stimulation (allP < 0.01).Conclusions These data show a significantly altered lncRNA expression profile in the LPS-induced inflammation of monocyte-derived macrophages, suggesting that lncRNA may be involved in regulation of macrophages inflammatory response.

With the continuous development in microfluidic fabrication technology, microfluidic analysis has evolved from a concept to one of research frontiers in last twenty years. The research of enzymes and enzyme inhibitors based on microfluidic devices has also made great progress. Microfluidic technology improved greatly the analytical performance of the research of enzymes and enzyme inhibitors by reducing the consumption of reagents, decreasing the analysis time, and developing automation. This review focuses on the development and classification of enzymes and enzyme inhibitors research based on microfluidic devices.

Objective To investigate the effects of body-weight support treadmill training(BWSTT) on function of lower limbs.Methods 46 hemiplegic patients after stroke were randomly divided into the therapy group(n=23) and control group(n=23).The subjects of both groups were administered with standardized rehabilitation program.The therapy group was also given BWSTT in addition.Both groups were evaluated before and after treatment using Functional Ambulation Category(FAC),Fugl-Meyer Assessment(FMA),Berg Balance Scale(BBS).Results Before treatment,there was no significant difference between these 2 groups in terms of scores with FAC,FMA and BBS.After treatment,both groups were significantly improved regard to their scores with FAC,FMA and BBS(P<0.01),with the therapy group scored significantly better than the control group(P<0.01).Conclusion BWSTT can significantly improve walk ability and balance function of the hemiplegic patients after stroke.

Objective To investigate the effects of lincRNA-cox2 on the polarization of murine RAW264. 7 macrophages by analyzing the expression of lincRNA-cox2 in RAW264. 7 macrophages of M1 and M2 phenotypes. Methods Murine RAW264. 7 cells were induced by IFN-γand LPS to polarize to M1 phenotype, and were induced by IL-4 to polarize to M2 phenotype. The expression of lincRNA-cox2 in M1 and M2 macrophages were analyzed by real-time quantitative PCR ( RT-PCR) . We designed and synthesized siRNA oligo for lincRNA-cox2 and unrelated sequences. Then the siRNA oligo and NC oligo were transfected into RAW264. 7 cells by LipofectmineTM 2000. The transfected RAW264. 7 cells were induced by IFN-γand LPS or by IL-4 to polarize to M1 or M2 macrophages. Enzyme linked immunosorbent assay ( ELISA) was performed to measure the secretion of IL-10 and IL-12 induced in different conditions. The expression of in-ducible nitric oxide synthase ( iNOS ) , TNF-α, arginase 1 ( Arg-1 ) and found in inflammatory zone 1 (Fizz1) at mRNA level were detected by RT-PCR. The M1 macrophages were transfected with siRNAs to knock down the expression of lincRNA-cox2 for analyzing the biological effects of lincRNA-cox2 on the polar-ization of macrophages. Results The relative expression of lincRNA-cox2 in M1 macrophages was signifi-cantly higher than that in RAW264. 7 cells and M2 macrophages. Compared with the control group, the RAW264. 7 cells transfected with lincRNA-cox2-siRNA showed decreased secretion of IL-12 and inhibited expression of iNOS and TNF-αat mRNA level after IFN-γand LPS induction, but increased secretion of IL-10 and enhanced expression of Arg1 and Fizz1 at mRNA level after IL-4 induction. Transfecting the M1 mac-rophages with lincRNA-cox2-siRNA inhibited the secretion of IL-12, but promoted the secretion of IL-10. Conclusion This study indicated that lincRNA-cox2 was involved in the regulation of macrophage pheno-types by promoting the polarization to M1 macrophages and inhibiting the polarization to M2 macrophages.
