0.05). Conclusion The quality of life of SARS patients was not high one month after discharged. The patients needed the further rehabilitation treatment including restoration of function and appropriate psychological treatment.

ObjectiveTo explore the effects of insomnia on heart rate variety(HRV) in aged hypertension patients. Methods259 subjects were divided into healthy group (74 cases),simple hypertension group (71 cases),coexisting hypertension and insomnia group (114 cases) which was sub-grouped to ＜5 years,5-9 years and ≥-10 years according to the duration of insomnia.All subjects had 24 h recordings of ECG.The data of HRV time domain (SDNN,SDANN and ASDNN) were collected and compared.ResultsHRV time domain was lower in healthy group than in the other two groups (F=12.02,10.54 and 4.27,P＜0.01),and decreased more significantly in coexisting hypertension and insomnia group compared with simple hypertension group(P＜0.01).The values of SDNN and SDANN in 5-9 years and ≥ 10 years subgroups decreased as compared with ＜ 5 years subgroup (F=8.63 and 4.54,P＜0.01),and these values further lower in ≥10 years subgroup than in 5-9 years subgroup (P＜ 0.01 ). ConclusionsInsomnia may lead to more serious disorder of automatic nervous system and further aggravated disorders appear in the elderly with hypertension along with increasing years of insomnia.

ObjectiveTo investigate the clinical efficacy of bidirectional Glenn shunt with noncardiopulmonary bypass(CPB) for treating congenital heart disease.MethodsThe clinical data of forty-four patients receiving bidirectional Glenn shunt from August 2005 to August 2011 were analyzedretrospectively,twenty-three cases of which were treated by bidirectional Glenn shunt with non-CPB (non-CPB group) and twenty-one with CPB (CPB group).The duration of ventilator-assisted breathing,chest drainage volume,amount of blood product usage,postoperative hospital stay and pulse oxygen saturation (SpO2) before leaving the hospital were compared and analyzed between two groups.ResultsForty-four patients were all cured.The duration of ventilator-assisted breathing,chest drainage volume and the amount of blood product usage of non-CPB group were less than those of CPB group [ (4.5 ± 1.3 ) h vs.(6.7 ± 1.5 ) h,(4.6 ± 1.4 ) ml/kg vs.(7.7 ± 3.1 ) ml/kg,( 221.8 ± 97.6 ) ml vs.( 423.4 ± 149.7 ) ml,P ＜ 0.05 ].There was no significant difference of the postoperative hospital stay and SpO2 before leaving the hospital between non-CPB group and CPB group[ (7.4 ± 2.3 ) d vs.(7.8 ± 1.9) d,0.91 ± 0.05 vs.0.88 ± 0.39,P ＞ 0.05 ].Conclusion Bidirectional Glenn shunt with non-CPB is a safe and feasible surgical approach,which is worthy of promotion.

Sixty-four patients with Graves' diseases were divided into methimazole group ( n =30 ) and propylthiouracil group( n =34 ).20 healthy volunteers were used as the control group.The levels of interleukin (IL) -2,IL-6,and TSH receptor antibody (TRAb) were determined by ELISA after serum samples were eollected before treatment and after treatment for 3 and 6 months.The results showed that the general data of two groups were not significantly different before treatment.IL-2 and IL-6 levels at 6 months after treatment were significantly different from the baseline (P＜ 0.05 ),IL-2 being gradually increased while IL-6 decreased with time.The level of IL-6 in methimazole group was lower than that in propylthiouracil group after treatment for 6 months ( P＜ 0.05 ).There was no significant difference in TRAb levels between two groups before treatment while differences became significant at 3 and 6 months of treatment ( all P＜ 0.01 ),being gradually decreased with time. IL-2/IL-6 ratio became significantly greater at 3 and 6 months of treatment compared with that before treatment in the same treatment group( P＜0.05 ) and the ratio in methimazole group was higher than that in propylthiouracil group by 6 months of treatment ( P＜0.05 ).IL-6level was positively correlated with FT3 and FT4 levels,and IL-2 level was negatively correlated with FT3,FT4,and TRAb levels in GD patients before treatment.The correlations of IL-2 and IL-6 with FT3 and FT4 disappeared by 3 and 6 months of treatment.IL-2 and IL-6 levels were related with TRAb level before and after treatment in methimazole group. These results suggest that the immunosuppressive effect of methimazole is more evident than that of propylthiouracil in patients with Graves' disease.

Objective To investigate the effects of a highly selective dopamine D4 receptor (ABT-724)on behaviors in Spontaneously hypertensive rats (SHR),a rat model of attention-deficit hyperactivity disorder (ADHD).Methods After intervention of methylphenidate(5mg/kg) and three different doses of ABT-724(0.04mg/kg,0.16mg/kg,0.64mg/kg),behaviors of SHR were verified by open-field test,Morris water maze and Làt maze.Results Number of square crossing after intervention of methylphenidate and ABT-724 in SHR( 70.67 ± 8.59,76.50 ± 10.75,79.17 ± 10.44,65.67 ± 20.62) was less than the saline control group( 130.33 ± 1 1.40) (P＜0.05).During Morris water maze,SHRs(52.50 ± 4.04,52.17 ± 2.99,61 ± 8.15,53.83 ± 9.87 ) after intervention of both had a better spatial memory ability than control group(38.83 ±7.17) (P＜0.05).In Làt maze,number of rearing after intervention of both in SHRs(57.17 ± 5.67,60.83 ± 8.28,55.17 ± 9.45,65.33 ± 9.50 ) was less than saline control group(78.00 ± 13.84) (P＜0.05).Conclusion ABT-724 could improve behaviors of spontaneous locomotor activity,cognitive ability,non-selective attention in SHR.

AIM: To improve the prevent efficacy of peptide p277 in autoimmune diabetes. METHODS: The recombinant expression plasmid pET28-Hsp65-6×p277 was constructed by inserting 6×p277 which were amplified by PCR into the vector pET28-Hsp65. The plasmid pET28-Hsp65-6×p277 was transformed into E.coli BL21 (DE3) and the fusion protein (Hsp65-6×p277) was expressed effectively as soluble protein after inducing by lactose. The fusion protein was purified and then used to immunize 4-week old female NOD mice with three times of i.n. inoculations in the absence of adjuvants. Serum samples from the immunized mice were collected at monthly interval. The concentrations of blood glucose and antibodies were measured by automatic analyzer. RESULTS: Administration with the Hsp65-6×p277 to NOD mice could prevent the development of diabetes. CONCLUSION: The fusion protein Hsp65-6×p277 might be further developed to a vaccine against insulin-dependent diabetes mellitus.

Objective:To observe the effects of hydrogen on osteogenic capacity of human periodontal ligament cells(hPDLCs)stim-ulated with P.g-LPS.Methods:hPDLCs were cultured and divided into 4 groups:control(C)group,osteogenic induction(OI) group,OI +1 00 ng/ml LPS(OILPS)group and OIPLS +3%H2 (H2 OIPLS)group,and treated respectively.Alizarin red staining (ARS)was carried out 3 weeks after treatment.ALP and OC mRNA expression of the cells was examined by RT-PCR after 7-d treat-ment.Results:LPS decreased A value of ARS(P <0.01 ),ALP mRNA expression(P <0.001 )and OC mRNA expression(P <0.001 )of the cells.H2 increased the A value(P <0.05),ALP mRNA expression(P <0.01 )and OC mRNA(P <0.01 )of the cells treated by LPS.Conclusion:High concentration of P.g-LPS can inhibit osteogenic capacity of hPDLCs,while hydrogen can impair the P.g-LPS induced suppression of hPDLC's osteogenesis.

Objective To investigate the relationship between blood vessel invasion (BVI) and clinicopathologic features and prognosis in patients with gastric cancer,and analyze related factors affecting the prognosis of patients.Methods The clinicopathological data of 206 patients with gastric cancer who were admitted to the Nanjing Hospital Affiliated to Nanjing Medical University from January 2007 to December 2010 were retrospectively analyzed.The BVI of surgical tumor specimens in all patients was detected by immunohistochemical staininng.All the patients were followed up via outpatient examination and telephone interview up to March 2014.The count data were analyzed using the chi-square test.The survival curve was drawn by Kaplan-Meier method.The survival analysis and univariate analysis were done using the Log-rank test,and multivariate analysis was done using the COX regression model.Results The BVI rate of 206 patients was 27.67％ (57/206).The BVI rate of tumor tissues,tumor differentiation,perineural invasion,T stage,N stage and TNM stage in all patients with gastric cancer were compared,showing significant differences (x2=14.396,9.569,15.579,43.453,30.732,P ＜ 0.05).After operation,188 patients were followed up for 6.0-60.0 months (median,34.0 months),with the follow-up rate of 91.26％ (188/206).Among 188 patients with follow-up,the median survival time and 5-year cumulative survival rate in patients with BVI and with negative BVI were 32.4 months and 19.6％,40.7 months and 42.0％,respectively,with a significant difference in the survival of patients (x2 =9.364,P ＜ 0.05).The results of univariate analysis showed that the diameter of tumor,tumor differentiation,perineural invasion,BVI,T stage,N stage and TNM stage were factors affecting the prognosis of patients with gastric cancer (x2=9.241,17.486,11.243,9.364,27.666,216.745,49.887,P ＜ 0.05).The results of multivariate analysis showed that the diameter of tumormore than 5 cm,BVI,stage T4,stage N3 and stage Ⅲ were independent risk factors affecting the prognosis of patients with gastric cancer (HR =0.502,0.456,0.052,0.001,0.735; 95％ confidence interval:0.334-0.754,0.289-0.720,0.004-0.664,0.000-0.006,0.159-3.398,P ＜ 0.05).Conclusions BVI in patients with gastric cancer is associated with the progression of tumors.The diameter of tumor more than 5cm,BVI,stage T4,stage N3 and stage Ⅲ are independent risk factors affecting the prognosis of patients with gastric cancer,and BVI may be a predictor of poor prognosis of patients with gastric cancer.

Objective To investigate the value of endoscopic ultrasonography (EUS) and abdominal CT (CT) in diagnosis of periampullary lesions and to make comparison between the two procedures. Methods The patients suspected of surrounding lesions of ampullary from 2009 to 2013 in our hospital were included in this study. All the patients received both EUS and abdominal CT. The accuracy rate of these two examination methods was compared. Results 151 patients were confirmed as surrounding lesions of ampullary, including choledocholithiasis, ampullary tumors, ampullary inflammation, tumors of the pancreatic head and pancreatic cysts. The accuracy rate of these diseases was 83.6%, 90.6%, 6.5%, 100.0%, and 100.0%for EUS;while was 52.2%, 56.3%, 43.5%, 91.3%, and 100.0%for abdominal CT. The tatal accuracy rate for diagnosing periampullary lesions by EUS was significantly higher than that by abdominal CT (84.1% vs. 59.6%). Conclusions Endoscopic ultrasonography has higher value in diagnosis of periampullary lesions, and its accurate rate was higher than that of abdominal CT.
