Eleven type 1 diabetic patients who received fixed regime of insulin Glargine were included in the study.The levels of fasting serum insulin were measured for each subject at 6:00 in three consecutive mornings.The variability of mean fasting serum insulin in each subject was 3.3%-41.5% (mean 15.4%).The variability did not correlate with the dose of Glargine statistically.

Objective To analyze the expression of synaptophysin (SY) in hippocampal dentate gyrus of rats with hypoxic-ischemic brain damage(HIBD) after the injection of bone marrow stromal cells(BMSCs) and its supernatant into the lateral ventricle and to explore the mechanism of potential effects. Methods Eighty 7-day-old sprague-dawley(SD) rats were randomly divided into sham group, control group, cell group and supernatant group, with 20 rats in each group. The HIBD model was established via the ligation of left carotid arteries followed by 2-hour hypoxia. One week later, control group was injected with 0.01 mol/L PBS via the left ventricle. Meanwhile, cell and supernatant group were injected with BMSCs and supernatant harvested from BMSC culture, respectively, via the same route. For spam group, the left carotid arteries were separated but not ligated, and no hypoxia treatment was imposed on this group. They also received 0.01mol/L PBS injection one week post surgery. After 8 weeks, the expression of SY in the dentate gyrus of rats was measured. Results Compared with sham group, model group showed significantly lower IOD (integral optical density) of SY positive material in the dentate gyrus(P < 0.05). Compared with model group, supernatant group and cell group exhibited significantly increased IOD values (P < 0.05), but there was no significant difference between cell group and supernatant group (P > 0.05). Conclusions BMSCs and supernatant injected via the lateral cerebral ventricle can increase SY expression in the hippocampal dentate gyrus of HIBD rats and promote synapse formation. The mechanism of this effect may be related to cytokine secretion by BMSCs which promotes synapse formation.

Objective To compare the effects of transforaminal peripheral nerve stimulation(PNS) and spinal cord stimulation(SCS) in treatment of postherpetic neuralgia.Methods A total of 64 patients with postherpetic neuralgia in our hospital from January 2015 to January 2016 were divided into PNS group and SCS group according to random number table.Both two groups were treated with PNS or SCS for 14 days,respectively.Visual analogue scale(VAS) and piasburgh sleep quality index(PSQI) were adapted to assess the effects at the different time of preoperation, postoperation 1 day,1 week,1 month,2 months.Results At the preoperation and 2 months postoperation,in PNS group,the VAS were (8.4±1.6) and (1.4±1.0),the PSQI were (16.1±2.1) and (5.8±1.3),respectively;meanwhile in the SCS group,the VAS were (8.6±1.8) and (2.9±1.2),the PSQI were (15.6±2.3),(7.5±1.5),respectively.Obviously,the VAS and PQSI at different follow-up stages were improved after transforaminal PNS or SCS treatment, the differences were signicant(P<0.05).Moreover,the PNS group had lower VAS and higher PQSI compared with the SCS group at different follow-up stages,the differences were signicant(P<0.05).Conclusion The transforaminal PNS achieved satisfying outcomes on pain relief and quality of sleep improvements for the postherpetic neuralgia patients,which was superior to that of the SCS.

Objective To analyze the differential expression of microRNA-146a (miR-146a) in monocyte-macrophage cell line (THP-1 cells) after induction by Cryptococcus neoformans (C.neoformans,reference strain WM148) or Cryptococcus gattii (C.gattii,reference strain R265),and investigate the mechanism of miR-146a in regulating the inflammatory response of cryptococcal meningitis.Methods The cultured THP-1 cells were divided into two groups to be induced by C.neoformans or C.gattii,respectively.THP-1 cells were induced with inactivated WN148 (or R265) strains at multiplicity of infection (MOI) of 5 in all experiments.The supematant and the cell pellet were collected separately after incubation.The expression of miR-146a was measured by real-time quantitative PCR (qRT-PCR) technique.The levels of TNF-u and IL-6 release were assayed by ELISA.Results The expression of miR-146a increased significantly in the C.neoformans induction group compared to 0 h.It reached peak at 3 h (P＜0.01),and then declined gradually.The level of TNF-α increased in supematant and reached peak at 12 h.The expression of IL-6 did not change significantly at each time point.The expression of miR-146a and TNF-α increased gradually and reached peak at 12 h in the C.gattii induction group (P ＜0.01),but the change did not reach statistical significance at 3 h,6 h time points.The expression of IL-6 gradually increased,and reached peak at 12 h time point.Conclusions Following stimulation with C.neoformans or C.gattii,the expression ofmiR-146a in THP-1 cells showed different patterns over time.The expression levels of TNF-α and IL-6 showed different patterns.These findings suggest that there may be different regulatory mechanisms in the THP-1 cells-associated inflammatory response after stimulation by inactivated C.neoformans and C.gattii strains.

Objective To investigate the health-related quality of life(HRQOL)of the recovered patients with depression and its influential factors.Methods From March 2008 to April 2009,150 depressive patients andergoing the following up treatment were recruited,and finally 124 patients rocovered,and quality of life for patients recovered were compared to published norms for the general Chinese people.The general demography material seale.Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),personality traits(Eysenck personality Inventory-EQP)the short form 36 item(SF-36)questionnaire and social support scale(SSS)were applied to an subjects.The SPSS 13.0 software for data processing,the group t test and the multiple linear regression analysis was adopted.Results ①The average score of seven domains of quality of life(RP,BP,GH,VT,SF,RE,MH )for the recovered patients were better than that of the pre-treatment patients(P<0.01),except the PF(89.23±14.09,87.23±16.81,t=1.044,P>0.05).But the average score of seven domains of quality of life for the re-covered patients were worse than that of the healthy people(P<0.01),except the PF(89.23±14.09,89.01±15.73,t=1.266,P>0.05).②The quality of life 0f the recovered patients remarkably related with the anxiety level, neuroticism, extraversion, recurrent depression,economic condition and social support(P<0. 01) . Conclusion The recovered depressive patient s health-related quality of life were improved significantly afer treatment, what were influenced by neuroticism,extraversion,anxiety as a trait,recurrent depression,economic condition and social support.Above mentioned factors should be taken into account when rehabilitation.

Objective To investigate the variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group [(25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.

Objective The combination of vasopressin and epinephrine has long been thought to be more effective then epinephrine alone in cardiopulrnonary resuscitation (CPR), evidence is not enough to make such a clinical recommendation. This meta-analysis compared the efficacy of vasopressin and epinephrine used together versus epinephrine alone in cardiac arrest (ca) in order to verify the truth. Method MEDLINE and EMBASE were searched for the data of randomized trials in comparing the results of co-administration of vasopressin and epinephrine with epinephrine alone in adults with cardiac arrest. The primary outcome was the restoration of spontaneous circulation (ROSC). Results Six randomized trials in 485 articles were analyzed. We failed to get the results supporting the effectiveness of this combination therapy, except for the rate of 24 hours survival (OR: 2.99,95%CI:1.43 ~ 6.28). No evidence supported that vasopressin combined with epinephrine was better than epinephrine alone in ROSC. Conclusions This systematic review indicates the combination of vasopressin and epinephrine is better for the rate of 24 hpurs survival in only 122 patients. Further investigation is needed to support the use of combination therapy for cardiac arrest.
