Objective To evaluate the correlation between pathological findings and clinical characteristics of patients with Sj(o)gren's syndrome (SS). Methods Eighty-four patients diagnosed with SS from 119 suspected ones at Peking University First Hospital were recruited. According to the pathological changes of lip biopsy, 64 patients were focus score (FS)( + ) and 20 patients were FS (-). In the FS( + ) group, 20 patients had germinal center (GC)( + ) and 44 patients had no GC. x2 test and t test were used for statistical analysis. Results The duration of symptoms of dry eyes or dry mouth in the FS (+) group was longer than that in the FS (-) group (P＜0.05). In the FS ( + ) patients, those with GC (+) had significantly longer duration of xerothalmia or xerostomia, higher serum IgG levels, greater FS score, and higher incidence of system involvement than those without GC patients (P＜0.05). In the FS (-) group, lip biopsies showed degenerative changes in 6 (30%) patients. Those with degenerative changes had longer duration of dry eyes and dry mouth and higher incidence of system involvement. Conclusion GC (+) in FS (+) patients and degenerative changes in FS (-) patients from lip biopsy are associated with severer clinical manifestations in patients with SS, suggesting that more clinical attention should be paid to this subgroup of patients.

Objective To investigate the feasibility of serum cardiac troponin T(cTnT) as a marker of cardiovascular events and hemodialysis (HD) adequacy in maintainence hemodialysis (MHD) patients.Methods Forty-seven cases of MHD patients were randomly divided into two groups (group A and group B).Group A received intermittent HD 4 h thrice one week,and group B received intermittent HD 4 h twice one week plus high-flux hemodiafiltration(HDF) 4 h once one week.Serum examination for blood biochemical indicator,cTnT and echocardiogram was performed every three months and at the time of recruitment.All the patients were followed up until the occurrence of death or cardiovascular events.Results After 3 months treatment,serum cTnT deceased significantly in group B compared with group A,and maintained the lower levels throughout the follow-up.E/A and LVEF had been reduced since 3 months treatment in group A,but stable in group B,E/A was lower in group A after 18 months treatment than that in group B,LVEF was lower in group A after 12 months treatment than that in group B.There were positive correlations between cTnT and E/A or LVEF in 42 cases who accomplished the follow-up of 12 months (r =0.54,0.66,P ＜0.05).Kaplan-Meier survival curve showed that the occurrence of cardiovascular events in patients with cTnT≥0.1μ g/L was higher than that with cTnT ＜0.1 μg/L in (28.5 ± 9.7) months' follow- up (Log-rank test: P =0.02).Both survival analysis and Cox analysis indicated that serum cTnT was a predictor of cardiovascular events in MHD patients.Conclusions Serum level of cTnT can be used as a marker of HD adequacy,and it is a predictor of cardiac events in MHD patients.Regular high-flux HDF increases the adequacy of HD treatment and improves the quality of life in MHD patients.

Objective To investigate the activation and clinical significance of the mammalian target of rapamycin (mTOR) pathway related protein and eukaryotic translation factor 4E-binding protein 1 (4E-BP1) in gastric cancer.Methods The activation of mTOR and 4E-BP1 in gastric cancer tissues of 38 surgical patients were detected by immunohistochemical method.The differences of phosphorylated mTOR and 4E-BP1 expression among cancerous tissues,para-cancerous tissues and normal gastric mucosa tissues and dinicopathological variables were analyzed by Chi square test and Kruskal-Wallis test.Results The positive expression rate of phosphorylated mTOR in the gastric cancerous tissues was significantly higher than that of para-cancerous tissues and normal tissues [71.1％ (27/38),50.0 ％ (19/38) and 44.7 ％ (17/38),x2 =11.031,P =0.026].The positive expression rate of downstream protein 4E-BP1 in the gastric cancer tissues was also significantly higher than that of paracancerous tissues and normal tissues [68.4％(26/38),57.9％(22/38) and 28.9％ (11/38),x2 =13.943,P=0.007].There was no correlation between phosphorylated mTOR and 4E-BP1 expression and tumor Lauren's sub-type,infiltration,differentiation degree,lymph node metastasis and patient's age.There was statistical significant difference between activated 4E-BP1 expression and tumor size in gastric cancer (H=3.86,P＜0.05).Conclsions mTOR pathway was over activated in gastric cancer.There was difference between phosphorylation degree of its downstream protein 4E-BP1 and the tumor size.

Objective To explore the difference of the oxytocin levels between social phobia patients and normal controls,and the relationship of symptoms severity of social phobia with the oxytocin levels and the relationship of drug effects with oxytocin levels.Methods Twenty seven 16-26 years old social phobia patients and thirty one normal controls were tested by an enzyme-linked immunosorbent assay to evaluate the oxytocin levels,and the Liebowitz Social Anxiety Scale was used to evaluate the symptoms severity of social phobia in patient group.Paroxetine was used to treat the patients with the drugs of 20mg per day,the Clinical Global Impression Scale were used to evaluate the drug effects after 4 weeks treatment.Results Mann-Whitney test showed there were significantly differences in oxytocin level between patients and controls ( (202.93 ± 145.06) pg/ml vs ( 152.29 ± 101.89 ) pg/ml,Z =- 1.307,P=0.030).Multiple liner regression analyses showed that the level of oxytocin was an impact factor of the severity of social phobia symptom (adjusted R2 =0.158,F=5.888,P=0.023 ).Logistic regression analyses showed that the level of oxytocin was an impact factor of the effective of drug treatment( OR=3.132,P =0.029 ).Conclusion This study indicate that the value of plasma oxytocin maybe significantly differences between social phobia and normal controls and the plasma oxytocin level maybe a factor which influence the symptoms severity and the effective of drug treatment in social phobia patients.

Objective To investigate the combined inhibition effect and the potential mechanism of rapamycin (mammalian target of rapamycin inhibitor) and PD98059 (mitogen-activated protein kinase/extracellular signal-regulated kinase kinase (MEK) inhibitor) on mouse colorectal cancer (CRC). Methods S-ICR mice were subcutaneously injected with 20 mg/kg of 1,2-dimethylhydrazine dihydrochloride in the nape for 20 weeks to induce CRC. From the 16th week, the mice were treated with alone or combined injection with 0.25 mg/kg rapamycin and 2.5 mg/kg PD98059. The drugs were administered for 8 weeks. Subsequently, the animals were sacrificed and dissected, the tumor sizes were measured, and the tumors were harvested for pathological assay. Furthermore, the phosphorylation of mTOR, p70S6K, and 4E-BPl proteins was detected by using immunohistoehemistry. Results The mice treated with rapamycin (44. 44 %) or PD 98059 (either alone (38.89%) or combination treatment (6.67%) were significantly less likely to develop cancer compared with mice receiving none of them (77.78%, P<0. 05). The average size of tumors was (6.15±2. 192), (8.85±3. 983), (2.917±0. 191), (16.36±6.855) mm3 respectively (P<0.05).The anti-cancer effect of the combination treatment was substantially significant. The proteins of phospho-mTOR, phospho-p70s6K and phospho-4E-BPl were significantly down-regulated after treatments (all P values < ,0.05). Conclusions Combined treatment was more effective than single-drug treatments of rapamycin or PD98059 alone for the prevention and treatment of mouse CRC. The mTOR signal pathway might be involved in the inhibitory mechanism.

ObjectiveTo investigate the status of benefit finding in diabetic patients,and mediating effect of resilience between family support and benefit finding in diabetic patients.MethodsFive hundred and thirteen diabetic patients from a hospital of Harbin were recruited as investigative subjects from September 2015 to June 2016.The resilience scale,family adaptability,cohesion scale and benefit finding scale were used in the study.ResultsThe scores of benefit finding,resilience and family adaptability and cohesion were 55.67±12.87,70.65±10.39 and 104.25±15.38,separately.The total score of family adaptability and cohesion was positively related to the total score of benefit finding(r=0.389,P<0.05).The total score of resilience was positively related to the total score of benefit finding(r=0.155,P<0.05).The total score of family adaptability and cohesion was positively related to the total score of resilience(r=0.112,P<0.05).Benefit finding as the dependent variable,the results of hierarchical regression analysis indicated that family adaptability and cohesion (β=0.382,P<0.01),resilience(β=0.098,P<0.01)entered the regression equation.There was a partial mediating effect of resilience between family support and benefit finding in diabetic patients.The mediating effect was 0.011,accounted for 2.8% of the total effect.The resilience was the important protective factor for benefit finding.ConclusionFamily support has a direct influence on benefit finding and an indirect effect mediated by resilience on benefit finding.

Background Clinical work found that triamcinolone acetonide (TA)bleeding during vitrectomy in proliferative diabetic retinopathy (PDR),but its mechanism is not clear.Objective This study was to explore the anastalsis of TA in vitrectomy for PDR.Methods A prospective study was performed.Twelve eyes of 12 patients who received vitrectomy combined with the intraocular use of TA for PDR were in cluded in Tianjin Medical University General Hospital from 2011 to 2014 and served as TA group.Thirty-two eyes of 32 patients who underwent vitrectomy for epimacular membrane or macular hole were enrolled as control group.The vitreous specimens of 0.6 ～0.8 ml was collected during the surgery.The concentrations of urokinase plasminogen activator (u-PA),tissue plasminogen activator (t-PA) and plasminogen activator inhibitors 1 (PAI-1) in vatreous were measured by ELISA.Results The mean contents u-PA,t-PA and PAI-1 in the vatreous were 25.45,127.44 and 0.42 ng/ml respectively in the TA group,and those the mean contents in the control group were 22.94,142.37 and 0.27 ng/ml respectively,shouwing a significant difference between the TA group and the control group (Z=-2.268,P＜0.05).NO significant difference was found in vitreous t-PA and PAI-1 between TA and control groups (Z =-0.092,-1.847,both at P＞0.05).Conclusions Vitreous u-PA content is increased in PDR eyes,which is more likely to lead bleeding.Anastalsis of TA during vitrectomy for PDR may be relatived to decreasing vitreous t-PA and u-PA contents as well as increasing PAI-1 contents.

Objective To evaluate the effects of body position and cuffed endotracheal tube (cETT) position on the intracuff pressure during tonsillectomy in the pediatric patients.Methods Sixty pediatric patients,aged 3-12 yr,scheduled for elective tonsillectomy under general anesthesia,were divided into group A and group B using a random number table,with 30 patients in each group.The cETTs were placed on one side of the blade of Davis retractor in group A.The cETTs were placed between the blade of Davis retractor and the body of tongue in group B.The intracuff pressure was recorded when the head was in the neutral position (T1),after changing to the head back position (T2) and when the retractor was placed for operation (T3).Results The intracuff pressure was significantly higher at T2 than at T1 in the two groups (P＜0.01).The intracuff pressure was significantly higher at T3 in group A and lower at T3 in group B than at T2 (P＜0.01).Compared with group A,the intracuff pressure was significantly decreased at T3 (P＜0.01),and no significant change was found in the intracuff pressure at T1,2 in group B (P＞0.05).Conclusion The intracuff pressure is affected by body position and cETT position during tonsillectomy in the pediatric patients,and routine monitoring of the intracuff pressure is recommended.
