Objective To investigate the clinical and laboratory characteristics of anticentromere antibody (ACA)and anti-SSA antibody expressions in patients with Primary Sj(o)gren's Syndrome (PSS). Methods Twelve PSS patients with ACA positive but SSA negative(ACA PSS)and 19 PSS patients with SSA positive but ACA negative(SSA PSS)were enrolled into the study and classified into two groups. We compared the age,laboratory data,occurrence of Raynaud's phenomenon(RP),and histological changes in minor labial salivary glands biopsies of the patients from two group. Results The mean age of the ACA PSS group(68.4 ± 7.9)years was significantly higher than that of the SSA PSS(54. 6 ± 16. 2)years group(P ＜ 0. 05). Serum IgG level of ACA PSS group(17. 89 ±4. 08)g/L was close to the normal range,which was significantly lower than that of SSA PSS(27.90 ±6. 72)(P ＜0. 01). Leukocytopenia was less frequently observed in ACA PSS than in SSA PSS(P ＜ 0. 05),the difference between two groups was statistically significant. We also found more frequent RP in the ACA PSS group than SSA PSS group(P ＜ 0. 05). Conclusions Our data confirm that ACA positive PSS differs from SSA positive PSS at several clinical respects and laboratorial examinations.

Objective To investigate the effect of continuous health education on the control of glucose and the changes of behavior. Methods One hundred and twenty-six newly diagnosed type 2 diabetic patients were randomly divided into control group and observation group,each group included 63 patients. The control group just received health education in hospitalization period,and the observation group received continuous health education both in and after hospitalization. The control of glucose and the changes of behavior were evaluated 3 months and 1 year later. Results After 3 months and 1 year treatment,the FPG,2hPG and HbA1c were significantly decreased compared to pre-treatment both in control group and observation group(P<0. 05). The FPG,2hPG and HbA1c were significantly decreased in the ob-servation group compared to the control groups(P<0. 05). The behaviors contained that mastery of diabetic knowledge,control of food in-take,persist in physical exercise, rational administration, self-monitoring of blood glucose and regular reexamination were significantly im-proved both in control group and observation group compared to pre-treatment (P<0. 05),and the behaviors were significantly improved in the observation group compared to the control group (P<0. 05). Conclusion Compared to control group,observation group had more ad-vantages in the control of glucose and the changes of behavior in newly diagnosed type 2 diabetic patients.

Objective To investigate the effect of the administrative intervention on smoking cessation of medical personnel and demonstrate the feasibility and the validity of this approach.Methods Two comparable hospitals were selected,one hospital with 136 smoking medical staff members was used as the intervention group;the other hospital which had 127 smoking medical staff members was used as the control group.We applied administrative intervention and health education to the intervention group and health education only to the control group.The intervention time was 10 months,we used the questionnaire survey before and after intervening to evaluate the smoking rate,the intention to quit smoking,the willingmess to accept the help of quitting and the proportion of those who quitted smoking.Results The smoking rate of intervention group (37.4％) was lower than that of control group (77.2％),the difference was statistically significant (x2=40.99,P＜0.01).The proportion of control group smokers in planning(51.1％) is statistically significant as compared with intervention group (46.18％) (x2=46.18,P＜0.01).The proportion of people who were willing to accept the help from families and friends and smoking cessation counseling in intervention group was significanly higher than that in the control group.(x2=10.04,x2=7.73,x2=7.58;P＜ 0.01).But the proportion of accepting the medicine for quitting smoking was not significantly different (x2=0.16,P＞0.05).The proportion of smokers who wanted to quit smoking on their own willingness in control group was significantly higher than that in intervention group (x2=36.27,P＜0.01).After10 months,61 people (46.6％) in the intervention group succeeded in quitting smoking and 13 (10.6％) people in control group succeeded (x2=28.21,P＜0.01).Conclusion Administrative intervention has feasibility and validity when hospitals take activities for smoking cessation.

Objective: To investigate the safety and efficacy of pingyangmycin (bleomycin A5) sclerotherapy for early peripheral arteriovenous malformations (AVM). Methods: Thirteen cases of early-stage [Schobinger clinical stage (Ⅰ/Ⅱ)] peripheral AVM patients (11 stage Ⅰ and 2 stage Ⅱ patients) aged between 3 months and 51 years were selected between January 2012 and May 2015. Pingyangmycin sclerotherapy injections were administered with B-scan ultrasonography or digital subtraction angiography positioning. All patients underwent relevant supplementary examinations before and after the procedure, and clinical evaluation was performed based on the improvement of the clinical symptoms of the patient and re-examination of lesion by imaging. Results: A total of 88 injections were administered to the 13 patients with an average of 6.7 injections per patient, 3-6 years of follow-up. Based on clinical evaluation, 7 patients were generally cured, 3 patients had significant improvement, 2 patients had partial improvement, and 1 patient had no improvement. Seven patients had different levels of postoperative swelling that resolved on its own. No serious complications occurred. Conclusions Pingyangmycin sclerotherapy for treatment of early peripheral AVM was effective and had few complications. It can control further progression of pathological changes.

Objective:To explore the association of peripheral blood neutrophil lymphocyte ratio(NLR) with primary osteoporosis (POP) in Chinese elderly women.Methods:From December 2015 to April 2019, a total of 788 elderly women in Chongqing Three Gorges Central Hospital were included in this study.They were divided into three groups according to bone mineral density: 242 cases of osteopenia, 206 cases of normal bone mineral density and 340 cases of osteoporosis.Their height, weight, statuses of bone of left femoral neck and results of blood tests were recorded, and the values of BMI, NLR and OSTA were calculated.The SPSS statistics software was used to analyze the differences of parameters among the three groups.Logistic regression analysis was used to get significant independent related factors for osteoporosis.The relationship of NLR and OSTA with T-score of left femoral neck was confirmed by Pearson correlation test.ROC curves were used to define the values of NLR and OSTA in diagnosis of osteoporosis.Results:There were statistically significant differences in age(median values: 66, 68 and 70, χ 2=71.596, P<0.001), BMI(median values: 23.46, 24.04 and 25.415, χ 2=64.936, P<0.001) and NLR(median values: 1.97, 2.435 and 2.84, χ 2=106.218, P<0.001) among the three groups(all P<0.01). Logistic regression analysis demonstrated that age, BMI and NLR were all independent significant related factors.There was correlation of NLR, OSTA with T-score of left femoral neck.In diagnosis of osteoporosis, the cut-off value, maximum Youden index, sensitivity and specificity were 2.395, 0.299, 70.3%, 59.6% for NLR, and -1.315, 0.174, 73.6%, 43.5% for OSTA. Conclusion:NLR has intermediate sensitivity and specificity in screening POP in Chinese elderly women, and deserves future researches.

Objective To analyze the frequency of interleukin (IL)-22+CD161+CD4+ T cells in the peripheral blood mononuclear cells (PBMCs) in rheumatoid arthritis (RA) patients compared with healthy control subjects and investigate the relationship of IL-22+CD4+CD161+ T lymphocyte frequency changes with RA disease activity.In addition to explore the pathogenesis of RA,and to look for new treatment targets for RA.Methods Twenty-one RA cases were included in the Department of Rheumatology of Tangshan Gongren Hospital from 2017 to 2018.Fourteen patients were female and 7 were male with the age ranged from 36 to 74 years old.The average age of this group of patients was (55±10) years,the average disease course was (60±50) months.All patients fulfilled the classification criteria of American College of Rheumatology [American College of Rheumatology (ACR)].Twenty-one subjects were enrolled as the control group,all of them came to Tangshan Gongren Hospital for regular health check-up.Fifteen subjects in the control group were female and 6 were male.Their age ranged between 40-78 years old with the average age of (55±9) years.IL-22+CD4+CD161+ T cells in PBMCs were detected by flow cytometry.The frequency variation of different CD4+CD161 + T was compared between case and control groups.The correlation was studied between the frequency and RA disease activity score (DAS28),tender joints number,swollen joints number,red blood cell sedimentation rate,high sensitive C reactive protein and white blood cell counts,red blood cell counts,platelet counts,IgG,IgA,IgM,complement C3 level,complement C4 level.T-test or Mann-Whitney U test were used for single-factor analysis,Pearson's test was used for correlation analysis.Results The percentage of RA group secreted CD4+ T cells (0.33± 0.20)％ of INF-γand IL-22,CD4+ T cells (0.51±0.29)％ of IL-22,and CD4+CD161+ T cells of IL-22 simultaneously.The number (0.55 ±0.28)％ was.significantly higher than that of the healtby control group [(0.22±0.14)％,(0.25±0.18)％,(0.36±0.24)％],and the differences were statistically significant [P=0.002,P=-0.0.45,P=0.026].Conclusion The percentage of IL-22+CD4+CD161+ T lymphocytes in the peripheral blood monocytes in RA patients is significantly higher than that in the healthy controls.The results of this study suggest that IL-22+CD4+CD161+ T lymphocytes in RA patients maybe related to RA disease activity and joint lesions.
