Objective To observe the effect of different analgesic methods including patient controlled epidural analgesia (PCEA) and patient controlled intravenous analgesia (PCIA) on stress response and anxiety in surgical patients with lower limb fracture. Methods A total of 120 surgical patients with lower limb fractures were employed and divided randomly into Groups PCEA, PCIA and C (40per group). All patients were anaesthetized by using combined spinal-epidural anesthesia. After operation, PCEA and PCIA were applied in the patients of Groups PCEA and PCIA, respectively. No analgesic method was employed in the Group C. The dynamic indices including mean blood press (MAP) and heart rate (HR), blood serum cortisol (COR) and blood sugar (BS) were measured at different time points,ie, T0 ( pre-anesthesia), T1 ( the end of the operation), T2 (24 hours after operation) and T3 (48 hours after operation). The visual analogue pain score was conducted at time points of T1, T2 and T3. The measurement of anxiety score was done at pre-operation and at days 1 and 7 after operation. Results There were no significant changes in HR and MAP of Groups PCEA and PCIA (P＞0.05, compared with T0) at every time point after operation. Whereas, HR and MAP of Group C were increased at time points of T1 and T2 (P ＜ 0.05, compared with T0 ), with statistical difference compared with Groups PCEA and PCIA at the same time points (P ＜ 0.05 ). VAS in Group PCEA was lower than that in Group PCIA at time points of T2 and T3 ( P ＜ 0.05). Meanwhile, VAS in Groups PCEA and PCIA was lower than that in Group C (P＜0. 05). COR and BS in Group PCEA were significant lower than those in group PCIA at time points of T2 and T3 (P ＜ 0. 05 ). Meanwhile, COR and BS in Groups PCEA and PCIA was lower than that in Group C (P＜0.05 or ＜0.01 ). Moreover, the changes were more significant in Group PCIA than that in Group PCEA (P ＜ 0. 05 ). The anxiety score in Groups PCEA and PCIA was lower than that in Group C (P ＜ 0.05). Conclusions Two analgesic methods of PCEA and PCIA can provide safe and effective postoperative analgesia and attenuate the stress response and anxiety in surgical patients with lower limb fracture. Meanwhile, PCEA takes more advantages than PCIA.

Background Heat shock proteins (HSPs) are highly conserved proteins that are induced in cells when confronted with a wide variety of proteotoxic stresses.HSP27 has a high degree of similarity with α-crystallin protein.The abnormality of HSP27 structure and expression are closely related to the formation of cataracts.Our previous study showed sodium salieylate has the protective effect on H2O2-induced lens damage.Objective This study was to investigate the roles of MAPK signal pathway in sodium salicylate-induced the expression of HSP27 in human lens epithelial cells (LECs) in vitro.Methods Human LECs were incubated in the fresh media containing sodium salicylate at different concentrations (0-55 mmol/L) for different times (1-5 hours) and allowed to be recovered in fresh medium without sodium salicylate for 1-24 hours with or without pretreatment with P38MAPK inhibitor (SB203580), ERK1/2 inhibitor (PD98059) and JNK/SAPK inhibitor ( SP600125). The expressions of P38MAPK, EBK1/2, JNK/SAPK, phosphorylated P38MAPK, phosphorylated ERK1/2, phosphorylated JNK/SAPK and HSP27 were detected by Western blot. HSP27 mRNA was detected by RT-PCR. The expression of HSP27 was also detected by immunohistochemistry. Results There was only weak expression of HSP27 in normal human LECs.After stimulation of 35-55 mmol/L sodium salicylate was removed and human LECs were cultured again for 6 hours,the expression of HSP27 in LECs were significantly increased ( F= 509. 953,P<0. 01). HSP27 was absent expressed in human LECs in 55 mmol/L sodium salicylate stimulation for 1-5 hours groups, but LECs were re-cultured for 3,6 hours after removed the stimulation, the expression of HSP27 was elevated (F = 452. 534, P<0. 01). Activation of P38 M APK occurred after sodium salicylate stimulation 30 minutes and 1 hour ( F = 865.68, P<0. 01). However, ERK 1/2 was expressed after sodium salicylate was eliminated for 1-6 hours ( F = 388.84, P<0. 01). JNK/SAPK was inactived by sodium salicylate. The expression of HSP27 could be down-regulated with the pretreatment of SB203580 and PD98059. Conclusion Sodium salicylatc can induce the expression of HSP27 in human (LECs) . The effects are mediated,at least in part ,through the activation of P38MAPK and ERK1/2 signaling pathway .

BACKGROUND: Stem cells are still controversial for the treatment of old myocardial infarction. Multimodal imaging evaluation is one of the key points in the study of stem cell transplantation, which can evaluate the therapeutic efficacy of stem cell transplantation from the perspective of molecular imaging. OBJECTIVE: To evaluate the therapeutic efficacy of coronary artery bypass graft (CABG) with different stem cell transplantation in patients with old myocardial infarction using multimodal imaging technology. METHODS: Sixty patients with old myocardial infarction were enrolled and randomly divided into three groups to receive CABG, CABG+autologous bone marrow stem cell transplantation (CABG+BMC) or CABG+autologous peripheral blood stem cell transplantation (CABG+PBSC), respectively. All the patients were scanned with gated PET/CT (13N-NH3?H2O/18F-FDG), echocardiography and coronary angiography at different time points orderly (at baseline, 1, 12 and 24 months after treatment). We compared the degree of coronary stenosis (%), left ventricular ejection fraction (LVEF), percentage of defect size with myocardial perfusion/metabolic abnormal radioactive distribution (A) and the ratio of defect area (R).RESULTS AND CONCLUSION: In the diagnosis of survival myocardial segments, the sensitivity, specificity, positive predictive value and negative predictive value for the gated PET/CT were 92.1%, 85.6%, 93.4% and 78.4%, respectively. After the above treatments, the extent of coronary stenosis decreased significantly in the three groups (P < 0.05), which was improved most at 1 month after treatment (P < 0.05). In the CABG+BMC and CABG+PBSC groups, the LVEF value increased significantly after treatment (P < 0.05). In the CABG+BMC group, the A value decreased significantly at 1 and 24 months after treatment as compared with the baseline (P < 0.05), and the A value was further decreased, indicating a significant difference at 12 and 24 months after treatment (P < 0.05). In the CABG+BMC group, the R value significantly decreased at 1 month after treatment compared with the baseline (P=0.019). To conclude, the multimodal imaging is better to evaluate the prognosis of patients undergoing CABG with different stem cell transplantation, which is beneficial for the selection of treatment and therapeutic evaluation in myocardial infarction patients. CABG combined with stem cell transplantation can improve the left ventricular function of patients in a short time, and CABG+BMC is superior to CABG+PBSC to improve the survived myocardial function in patients.

OBJECTIVETo evaluate the safety and effectiveness of GreenLight 120-W laser photoselective vaporization of the prostate (PVP) versus transurethral resection of the prostate (TURP) for benign prostatic hyperplasia (BPH).

METHODSWe searched PubMed, Medline, Embase, Cochrane Library, Wanfang, CNKI, and VIP for randomized control trials and their references addressing 120-W PVP versus TURP in the treatment of BPH. Based on the inclusion and exclusion criteria, two reviewers independently accomplished the screening, quality assessment, and data extraction of the identified studies and performed meta-analyses using RevMan 5.2.

RESULTSTotally, 6 randomized control trials were included in this analysis, involving 703 cases, 351 treated by PVP and 352 by TURP. Compared with TURP, PVP showed significantly decreased time of catheterization (by 32. 55 hours, 95% CI 15.3 -49.8, P < 0.01), hospital stay (by 1.85 days, 95% CI 1.2-2.5, P < 0.01), and intraoperative blood loss (by 15.6 g/L, 95% CI 10.0-21.2, P < 0.01), but increased time of operation (by 9.37 minutes, 95% CI 5. 1-13.6, P < 0.01). There was also a significant reduction in blood transfusion, TUR syndrome, and capsular perforation in the PVP group. At 12 months after surgery, no statistically significant differences were found between the two groups in the improvement of maximum urinary flow rate, IPSS, postvoid residual, and sexual function.

CONCLUSIONGreenLight 120-W laser PVP is a safe and effective procedure for the treatment of BPH, with similar effectiveness to TURP but less blood loss, shorter time of catheterization and hospital stay, and lower incidences of blood transfusion, TUR syndrome and capsular perforation.

Eight compounds from six Chrysanthemum morifolium cv. 'Hangju' were determined and multivariate statistics, including principle component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) were used to investigate the potential damaging effect of sulfr-fumigating process. Meanwhile, S, Mn, Fe, Cu, Pb were also detected by using ICP-MS and ICP-OES. In this study, dramatic chemical changes were found that the contents of flavonoid aglycones remarkably increased while those of glycosides and hydroxycinnamoylquinic acids were significantly reduced. The PCA score plots showed six samples were clearly classified into the non-fumigated and sulfur-fumigated types. And according to VIP > 1, the most important chemical markers were luteolin, apigenin and luteolin-7-O-glucoside which indicated that the extracted three components might have a marked effect on the discrimination among different group samples. And then, it was found that the residue of sulfur of SHJ were significantly higher than NHJ (P < 0.05). The established approach was applied to rapidly discriminate sulfur-fumigated HJ with combining the quantitative chemical analysis and multivariate statistical analysis, and then the result will provide some evidence to evaluat the quality of HJ and control its processing.

OBJECTIVETo verify the efficacy of Jianpi-xingniao needling therapy on prevention and treatment of motion sickness.

METHODSSixty volunteers of motion sickness were randomized into an acupuncture group and a delayed acupuncture group, 30 cases in each one. In the acupuncture group, acupuncture was given at Baihui (GV 20), Sishencong (EX-HN 1), Neiguan (PC 6), Zusanli (ST 36) and Hegu (LI 4). The needles were retained for 20 min. The treatment was given twice a week and 10 treatments were required. In the delayed acupuncture group, acupuncture was postponed, meaning no acupuncture during observation stage. Graybel scale was adopted to observe the score of symptoms and physical signs of the subjects of motion sickness before and after intervention. The efficacy was compared between the two groups.

RESULTSTwenty-five cases in the acupuncture group and 22 cases in the delayed acupuncture group were included in the statistical analysis. The score of symptoms and physical signs of motion sickness was reduced significantly after treatment in the acupuncture group as compared with that before treatment (10.12 +/- 3.37 vs 0.92 +/- 0.40, P < 0.05). The score in the acupuncture group was lower apparently than that in the delayed acupuncture group (0.92 +/- 0.40 vs 9.86 +/- 2.53, P < 0.05). The difference was not significant before and after treatment in the self-comparison of the delayed acupuncture group (P > 0.05). The total effective rate was 96.0% (24/25) in the acupuncture group, which was significantly better than 0.0% (0/22) in the delayed acupuncture group (P < 0.01).

CONCLUSIONJianpixingniao needling therapy relieves the symptoms of motion sickness in the patients and achieves a better clinical efficacy.
