Objective To observe the interference of glucose-6-phosphate dehydrogenase (G6PD) deficiency on glycated hemoglobin (HbA1c) detected by three measurement systems.Methods A total of 286 cases of blood and serum samples were collected at Zhongshan Hospital of Sun Yat-Sun University from August 2012 to April 2016.The blood samples were divided into healthy control group (122 cases),diabetes group (82 cases),glucose-6-phosphate dehydrogenase deficiency group (61 cases) and diabetes with G6PD deficiency group (21 cases).The levels of HbA1 c were detected by three measurement systems,including Primus Ultra2,Variant lⅡ Turbo 2.0 and Modular P.The results of HbA1c were converted into the estimated average blood glucose concentration (eAG).The values of A eAG-FPG in different groups were calculated and statistical analysis was performed for evaluation of the differences from the three measurement systems.Results The HbA1c results measured by the three systems and AeAG-FPG values in G6PD deficiency group were all lower than healthy control group(all P ＜0.05).The measured results were similar in both diabetes group and diabetes with G6PD deficiency group.Conclusion G6PD deficiency may cause false H-bA1c results detected by three measurement systems.In the case of HbA1c for evaluating blood glucose control,the interference of G6PD deficiency should be noticed.

Objective To study the treatment efficacy of auricular point sticking for primary dysmenorrhea in college students, and to seek a convenient effective treatment method for primary dysmenorrhea.Method A total of 144 female college students with primary dysmenorrhea were randomized into an auricular point sticking group, a medication group, and a blank control group to receive the corresponding intervention. The dysmenorrhea intensity score and traditional Chinese medicine symptoms score for dysmenorrhea were used for observation.Result After the intervention, the recovery rate and total effective rate were respectively 64.6% and 91.7% in the auricular point sticking group, versus 39.6% and 70.8% in the medication group. There was a significant difference in comparing the therapeutic efficacy between the auricular point sticking group and medication group (P<0.05).Conclusion Auricular point sticking can produce a significant efficacy in treating primary dysmenorrhea in female college students, without adverse effects and convenient, and has a content long-term efficacy.

Objective: To investigate the personal wellbeing index (PWI) among elderly aged 55 and above from the elderly day care centers in Macao, Hong Kong and Guangzhou, and associated factors. Methods: We used convenient sampling to select participants from 16 elderly day care centers in Macao, Hong Kong and Guangzhou. Inclusion criteria were: females aged 55 or above, males 60 or above, the participants who were conscious and clearly understood the questionnaire. Informed consent form was signed by the participants. A total of 324 elderly participated in the study: 90 from Macao, 100 from Hong Kong, and 134 from Guangzhou. Close-end questionnaire was used to collect demographic information and PWI inventory (Cantonese version) was used to assess the PWI scores. Comparison in the PWI scores difference was conducted. Multiple regression method was used to analyze factors associated with PWI. Results: The PWI was 7.3±1.9 (Macao: 7.7±1.9, Hong Kong: 7.2±1.7, Guangzhou: 7.0±1.9) (F=3.32, P=0.037). The multiple regression analysis showed that comparing to those who did exercised 3 times or less, or single/devoiced/separated, or had no education, the elderly who did exercised 4 times or more per week or married/widowed, or received education in primary school or above had higher PWI scores. The beta values (95%CI) were 0.82 (95% CI: 0.31-1.34), 1.03 (95% CI: 0.12-1.94), 0.51 (95% CI: 0.04-0.99) respectively. Conclusion The elderly participants aged 55 or above who went to elderly day care centers in three cities had higher PWI score generally. Marital status, participate in sufficient physical activity and advanced education level were significant related to PWI.

Objective To assess and compare the efficacy and safety of ecabet sodium-based quadruple therapy versus bismuth-based quadruple therapy for Helicobacter pylori (Hp) eradication.Methods A multicenter,randomized,positive controlled clinical trial was carried out.The object of the study were chronic gastritis patients at 8 hospitals in Xi'an,Beijing,Shanghai and Guangzhou from June 2009 to June 2011.All patients were divided into treatment group and control group.In treatment group,patients received ecabet sodium-based quadruple therapy (two times per day,omeprazole magnesium 20 mg,amoxicillin 1000 mg,clarithromycin 500 mg and ecabet sodium 1.0 g each time for 10 days.In control group,patients were assigned to receive bismuth-based quadruple therapy (two times per day; omeprazole magnesium 20 mg,amoxicillin 1000 mg,clarithromycin 500 mg and bismuth potassium citrate 220 mg each time) for 10 days.The Hp eradication was determined by 13C or 14C urea breath test at the 38th day after the treatment and the eradication rate was calculated.Side effects were recorded and analyzed.The data were analyzed by chi square test and Fisher's exact test.Results A total of 311 patients were recruited,and 155 patients were allatted in treatment group and 156 in control group.The per-protocol (PP) analysis indicated that the eradication rates of treatment group arid control group were 75.71％(106/140) and 77.37％(106/137) respectively,and there was no significant difference x2 =0.106,P=0.745).The intention-to-treat (ITT) analysis indicated that the eradication rates of treatment group and control group were 68.39％ (106/155) and 67.95％ (106/156) respectively,and there was no significant difference x2 =0.007,P=0.934).The side effects rates of treatment group and control group were 20.00％ (31/155) and 25.64％(40/156) respectively,and the difference was not statistically significant (Fisher's exact test,P=0.280).No serious side effect was observed in two groups.Conclusion The efficacy and safety of ecabet sodium-based quadruple therapy for Hp eradication in chronic gastritis patients may be the same as bismuth-based quadruple therapy.
