Objective:To observe the effect of dezocine preemptive analgesia on infraclavicular brachial plexus block and the im-pact of it on postoperative analgesia.Methods:Sixty patients,who were classified by American Society of Anesthesiologists (ASA)criteria as classⅠ-Ⅱ and underwent infraclavicular brachial plexus block,were divided randomly into three groups, with 20 cases in each group.In Group A,5 mg dezocine was combined with local anesthetics(20 mL 0.375 % ropivacaine,15 mL 1% lidocaine and 1mL 1∶200 000 epinephrine)for infraclavicular brachial plexus block;in Group B,5mg dezocine was in-travenously injected 15 minutes before the operation and then the same local anesthetics were used;in Group C,infraclavicular brachial plexus block was performed only with the same local anesthetics.The onset time of anesthesia and the operation time, the visual analogue scale (VAS)at 1 h after anesthesia and 8,12,24,36,48 h after operation and the postoperative analgesia time(the time from the end point of operation to the time point when VAS>3),as well as the side effects were recorded.Re-sults:The onset time of anesthesia in Group A were shorter than that in Group B and C(P <0.05).The VAS at 8 h after operation in Group A and B were significantly lower than that in Group C(P <0.05).The VAS at postoperative 12 and 24 h in Group A were significantly lower than those in Group B and C.There was no statistically significant difference in VAS score at 1 h after anesthesia and at 4,36,48 h after operation among the three groups(P >0.05).The analgesia duration was gradually decreased in Group A ,B and C(P <0.05).There was no statistically significant difference between Group A and B in the in-cidence of side effects.Conclusions:The dezocine preemptive analgesia has exact effect.It could prolong the duration of posto-perative analgesia and has few side effects.

Objective To explore the disruption of circadian rhythm induced by the alteration of il?lumination leads to cognition impairement and mood dysreguation in mice. Methods 36 male C57BL/6 mice were divided into constant light group( CL) ,normal light group( N) and constant darkness group( CD) . Open field test was applied for the comparison of locomotor activity,tail suspension test and forced swimming test were conducted for assessment of mood state,and elevated plus?maze and Morris water maze were con?ducted for assessment of cognitive function. Results ( 1) Different circadian rhythms did not change the lo?comotor activity among three groups (CL:(200 160.00±955.28)cm,N:(208 148.00±578.11)cm,CD:(179 128.00±1 185.80)cm, P>0.05). (2) Compared with the control group,CL and CD mice showed significantly decreased immobility time in both TST (CD:(40.16±3.82)s,N:(18.83±2.27)s,CL:(46.00±2.80)s, P<0.01) and FST(CD:(181.33±9.03)s,N:(118.83±7.68)s,CL:(151.83±3.06)s, P<0.05). (3) Compared with the control group,CL and CD mice spent less time (CD:(21.76±6.88)s,N:(80.67±11.19)s,CL:(12.50±5.23)s, P<0.05) and made fewer entries (CD:3.33±0.49,N:6.83±0.91,CL:2.00±0.77, P<0.05) into open arms in elevated plus?maze, and exhibited less crossings in target quarter in Morris water maze (CL:2.67±0.76,N:5.00±0.26,CD:2.83±0.40, P<0.05). Conclusion Chronic constant light or darkness leads to negative impacts on mood and cognition in mice.

The etiology of deep vein thrombosis (DVT) is still not elucidated nowadays. Based on the accordance between DVT incidence and the anemophilous pollen concentration in the air, we proposed the hypothesis that allergic reaction induced by anemophilous pollen may cause "idiopathic" DVT, and proinflammatory factors may play an important role in the thrombosis process.

Ebolavirus can cause hemorrhagic fever in humans with a mortality rate of 50%-90%. Currently, no approved vaccines and antiviral therapies are available. Human TIM1 is considered as an attachment factor for EBOV, enhancing viral infection through interaction with PS located on the viral envelope. However, reasons underlying the preferable usage of hTIM-1, but not other PS binding receptors by filovirus, remain unknown. We firstly demonstrated a direct interaction between hTIM-1 and EBOV GP in vitro and determined the crystal structures of the Ig V domains of hTIM-1 and hTIM-4. The binding region in hTIM-1 to EBOV GP was mapped by chimeras and mutation assays, which were designed based on structural analysis. Pseudovirion infection assays performed using hTIM-1 and its homologs as well as point mutants verified the location of the GP binding site and the importance of EBOV GP-hTIM-1 interaction in EBOV cellular entry.

Objective To investigate the knowledge, attitude, behavior about Dietary Guidelines for Chinese (2007) among elderly residents in 2 communities in Wenzhou City, and to exoplore the appropriate method for dietary intervention for elderly people. Methods A questionnaire survey was carried out in 784 people aged 50 years and above in two communities in Wenzhou from December, 2014 to January, 2015 about Dietary Guidelines for Chinese (2007) .The awareness of knowledge, attitude and behavior about nutrition were recorded, and multiple linear regressions were taken to evaluate the impression of knowledge. Results The awareness rate of knowledge was 58.28%, and the awareness about 'Which is the healthiest way to cook?' was the hot question (89.29%) while 'Which disease can be prevented by eating iodized salt?' was not (0.89%) . And 53.06% of respondents interested in nutrient knowledge, and 14.54% of them thought they had learned the knowledge about nutrition, and 39.54% of them thought knowledge had impact on health, and 76.53% of them would like to change their unhealthy dietary behavior. About 50.89% of respondents got knowledge about nutrition from TV or radio programs. Intake frequency about vegetables and fish were 88.01% and 62.63%respectively, while intake frequency about milk and milk products and beans and their products were 21.43% and 15.43%respectively. Multiple linear regression promoted that, female, a high degree of education, less number of offspring, people who had married, people whose income came from social insurance had positive impact on the awareness rate of knowledge. Conclusion The awareness rate of knowledge among elderly people was low, and intake frequency about milk and milk products and beans and their products were efficient. But they would like to change their unhealthy behavior. Long-term education about nutrition should be taken for elderly people.

OBJECTIVE: To evaluate the benefits and toxicities of different corticosteroid regimes in preventing relapse in children with steroid sensitive nephrotic syndrome (SSNS). METHODS: MEDLINE (Jan. 1963-Mar. 2007), elsevier (Jan. 1997-Aug. 2006), OVID databank (Jan. 1993-Aug. 2006), Springer databank (Jan. 1994-March 2007), the Cochrane Controlled Trials Register (Cochrane Library, Issue Feb. 2006), Cochrane Renal Group Specialised Register (Jul. 2006), EMBASE (Jan. 1980-Mar. 2007) and CNKI (Jan. 1994-Mar. 2007) etc, were searched by the terms primary nephrotic syndrome, glucocorticoid, corticosteroid, steroid, prednisone, methylprednisolone, dexamethasone and children etc for the human clinical trials about glucocorticoid (GC) administration in primary nephrotic syndrome (PNS) (aged 3 months to 18 years), controlled or semi-controlled ones, including unpublished documents from scientific meetings and theses, and similar documents listed in the references of the above documents were also included. All the studies were evaluated strictly according to Jadad Standard, and the Meta-analysis were adopted. Review manager 4.2 software was used to analyze the data. The odds ratio was calculated for the relapse rate and side effect from the initial episode to the end of follow-up between the patients treated with corticosteroids and the controls. RESULTS: Totally 12 trials with 868 subjects meeting the criteria were included in this review. A Meta-analysis of 7 trials, which compared between 2 months of prednisone and 3 months or more in the first episode, showed that longer treatment duration significantly reduced the risk of relapse at 12-24 months (RR=0.70,95% CI:0.60-0.89),without an increase of side effect. There was a negative linear relationship between the duration of treatment and risk of relapse (r2 =0.66, P=0.05). CONCLUSION (1) Children in their first episode of SSNS should be treated for at least 3 months of GC. The therapeutic effect of patients in the primary nephrotic syndrome treated with GC for 12 weeks was prior to that for 8 weeks, compared with that in the controls. It could reduce the relapse rate of half year, the longer treatment duration in the NS patients at the first relapse was, the lower relapse risk was.(2) Compared with alternative GC administration, standard GC administration can reduce the side effects; Course more than 1 year of GC administration can reduce the 2-year relapse rate. Hence in children who relapse frequently, multicentre, well-designed experiments should be adopted.

OBJECTIVE: To investigate the efficacy and adverse effect of mycophenolate mofetil (MMF) in the treatment of frequently relapsing nephrotic syndrome in children. METHODS: The study population consisted of 37 children (24 simple nephrotic syndrome and 13 nephritis-type syndrome) suffering from frequently relapsing nephrotic syndrome. Patients received 20-30 mg/(kg d) of MMF in conjunction with 1 mg/(kg d) prednisone for 3-6 months. RESULTS: Out of 24 patients suffered from simple nephrotic syndrome, 17 patients (70.8%) with complete relief, 4 patients (16.7%) with partial relief and 3 patients (12.5%) with non-relief, whereas out of 13 patients suffered from nephritis-type syndrome 6 patients (46.2%) with complete relief, 3 patients (23.1%) with partial relief and 4 patients (30.7%) with non-relief. Eight patients with Minimal Change Disease (MCD) achieved complete relief. Of 23 patients with Mesangial Proliferative Glomerulonephritis (MsPGN) or Membranoproliferative Glomerulonephritis (MPGN), complete relief was observed in 17 patients (73.9%), partial relief in 4 patients (17.4%) and non-relief in 2 patients. CONCLUSION These Results suggest that MMF has better efficacy against simple renal disease than against nephritis-type syndrome, and MMF may be more suitable for the treatment of frequently relapsing nephrotic syndrome characterized by proliferative lesions.

OBJECTIVE: To explore the relationship between pathological features and clinical manifestations in children with nephropathy under 6 years old. METHODS: Renal biopsy by rapid percutaneous puncturation was performed on 313 children under 6 who were all diagnosed clinically as kidney diseases of 14 different kinds. The specimens were divided into 3 parts for microscope, electron microscope and immuno fluorescence examination respectively and processed by HE, PAS, PASM, and Masson staining. Immunofluorescence was used to detect the deposition of IgG, IgM, IgA, C3, C4, C1q, and Fb in the renal tissues. Additional examinations were done to detect HBs-Ag, HBeAg and HBcAg deposition in some cases with positive serum HBs-Ag. Altogether 290 of the specimens (290/313, 92.65%) were examined by electron microscope. RESULTS: All the renal biopsy performances were successful. The clinical manifestations comprised of persistent haematuria (32.92%, 103/313), idiopathic nephritic syndrome (26.1%, 82/313), acute nephritic syndrome (20.14%, 63/313), Henoch Schonlein purpura nephritis (8.32%, 26/313), HBV-nephritis (4.79%, 15/313), and isolated proteinuria (2.56%, 8/313). The main pathological patterns of glomerular disease were identified as mesangial proliferation (51.75%, 162/313), IgM nephropathy (8.31%,26/313), minor and minimal change (7.99%, 25/313), IgA nephropathy (7.35%, 23/313), endocapillary proliferative glomerulonephritis (5.11%, 16/313), focus segmental glomerulosclerosis (4.47%, 14/313), thin basement membrane nephropathy (4.47%, 14/313), and membrane nephropathy (4.47%, 14/313). Alport syndrome, congenital nephrotic syndrome, and thin basement membrane nephropathy can be diagnosed by electron microscope, white IgA nephropathy, IgM nephropathy and C1q nephropathy by immunopathology. CONCLUSION Similar clinical manifestations may differ in the pathology and the clinical features of one pathological diagnosis may vary greatly. Renal biopsy is of great help to the diagnosis, treatment and the prognosis evaluation for children with nephropathy under 6. Electron microscopes also play an important role in the diagnosis of nephropathy.
