BACKGROUND: The global rise in diabetes prevalence is a pressing concern. Despite initiatives like "The Healthy Beijing Action 2020-2030" advocating for increased awareness, treatment, and control, the specific situation in Beijing remains unexplored. This study aimed to analyze the trends in diabetes prevalence, awareness, treatment, and control among Beijing adults. METHODS: Through a stratified multistage probability cluster sampling method, a series of representative cross-sectional surveys were conducted in Beijing from 2005 to 2022, targeting adults aged 18-79 years. A face-to-face questionnaire, along with body measurements and laboratory tests, were administered to 111,943 participants. Data from all survey were age- and/or gender-standardized based on the 2020 Beijing census population. Annual percentage rate change (APC) or average annual percentage rate change (AAPC) was calculated to determine prevalence trends over time. Complex sampling logistic regression models were employed to explore the relationship between various characteristics and diabetes. RESULTS: From 2005 to 2022, the total prevalence of diabetes among Beijing adults aged 18-79 years increased from 9.6% (95% CI: 8.8-10.4%) to 13.9% (95% CI: 13.1-14.7%), with an APC/AAPC of 2.1% (95% CI: 1.1-3.2%, P <0.05). Significant increases were observed among adults aged 18-39 years and rural residents. Undiagnosed diabetes rose from 3.5% (95% CI: 3.2-4.0%) to 7.2% (95% CI: 6.6-7.9%) with an APC/AAPC of 4.1% (95% CI: 0.5-7.3%, P <0.05). However, diabetes awareness and treatment rates showed annual declines of 1.4% (95% CI: -3.0% to -0.2%, P <0.05) and 1.3% (95% CI: -2.6% to -0.2%, P <0.05), respectively. The diabetes control rate decreased from 21.5% to 19.1%, although not statistically significant (APC/AAPC = -1.5%, 95% CI: -5.6% to 1.9%). Overweight and obesity were identified as risk factors for diabetes, with ORs of 1.65 (95% CI: 1.38-1.98) and 2.48 (95% CI: 2.07-2.99), respectively. CONCLUSIONS The prevalence of diabetes in Beijing has significantly increased between 2005 and 2022, particularly among young adults and rural residents. Meanwhile, there has been a concerning decrease in diabetes awareness and treatment rates, while control rates have remained stagnant. Regular blood glucose testing, especially among adults aged 18-59 years, should be warranted. Furthermore, being male, elderly, overweight, or obese was associated with higher diabetes risk, suggesting the needs for targeted management strategies.

Objective:To understand the awareness of smoking hazards and intention of smoking concession in residents aged 18-65 years in Beijing, and provide scientific evidence for the development and improvement of tobacco control policies and measures.Methods:Data were collected from the 2017 Beijing Non-communicable and Chronic Disease surveillance. A multi-stage stratified cluster sampling method was used to take samples from 165 communities in 16 districts of Beijing. Logistic regression was used to analyze the influencing factors.Results:Among 11 594 participants, 49.93% had no intention of smoking concession. The percentage of refusing smoking concession was higher in men (50.39%) than in women (43.01%), the difference was significant ( χ2=14.211, P=0.002), and higher in suburban residents (56.78%) than in urban residents (45.30%), the difference was significant ( χ2=51.977, P<0.001). For the smoking cessation motivation, "illness" was the reason for more former smokers (29.88%) compared with current smokers (11.50%), the difference was significant ( χ2=85.865, P<0.001). The awareness rates of smoking hazards was higher in women (34.97%) than in men (32.63%), the difference was significant ( Z=5.612, P<0.001), higher in suburban residents (35.44%) than in urban residents (33.03%), the difference was significant ( Z=-3.734, P<0.001), and higher in never smokers (35.15%) than in smokers (30.06%), the difference was significant ( χ2=62.277, P=0.005). Multiple logistic regression analysis results showed people with general awareness ( OR=0.61, 95 %CI: 0.39-0.94) and poor awareness ( OR=0.67, 95 %CI: 0.50-0.90) of smoking hazards were less likely to quit smoking and people with general awareness ( OR=0.64, 95 %CI: 0.53-0.76) and poor awareness ( OR=0.87, 95 %CI: 0.78-0.98) of smoking hazards were more likely to smoke. Conclusions:Smokers aged 18-65 in Beijing had low willingness for smoking cessation. Health problem was main consideration for smoking cessation. Never-smokers had better awareness of smoking hazards than smokers, and the awareness of smoking hazards was an influencing factor of smoking status.

Objective:To understand the status quo of sleep and its associations with serum hemoglobin A1c (HbA1c) among nondiabetic people of 18-79 years old in Beijing.Methods:Data was gathered from the 2017 Beijing Non-communicable and Chronic Disease Surveillance Program. Multiple classified clusters sampling method was used while the 18-79 years old were sampled from the 16 districts of Beijing. Questionnaires would include information on demographic characteristics, chronic diseases and related risk factors, sleep duration and related problems (snore/asphyxia, difficult to get to sleep, waking often during the night, waking up early or taking sleeping pills) within the last 30 days. Complex sampling logistic regression models were established to analyze the association between sleep-related problems and serum HbA1c.Results:A total of 11 608 non-diabetic participants were involved in this study, with average age, reported sleep duration and median of serum HbA1c level as (43.36±15.27) years old, (7.49±1.29) h/d and 5.30%, respectively. 47.38% of them reported having sleep problems within the last 30 days. With the increasing time of sleep, serum HbA1c level was fluctuating significantly ( F=413.06, P<0.01). Significant differences appeared in serum HbA1c levels among different age groups ( t=358.3, P<0.01). Among participants with several kinds of sleep problems, the serum HbA1c levels were significantly higher than those without, through the single factor analysis ( U=15.11, P<0.01). After adjusting for potential confounding factors, the combination of one sleep-related problem ( OR=1.21, 95% CI: 1.03-1.41) and snore/asphyxia were associated with higher serum HbA1c levels (HbA1c≥5.7%) ( OR=1.37, 95% CI: 1.16-1.61). People under 60 years of age were with higher risk of having higher serum HbA1c levels. Conclusion:Duration and sleep-related problems might affect the serum HbA1c levels, especially among those younger than 60 years of age.

OBJECTIVE: To determine the incidence and genotypes of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Dongguan region of Guangdong Province and assess the efficacy and feasibility of flow-through hybridization. METHODS: Peripheral blood samples were randomly selected and detected by modified G6PD/6PGD ratio method. Flow-through hybridization was used to detect 14 G6PD mutations among all samples. RESULTS: In total 1005 samples were collected, the detection rate for modified G6PD/6PGD ratio method and flow-through hybridization were 2.79% and 20.90%, respectively. The consistency of the two methods was poor(Kappa=0.187). When c.1311C>T mutation is excluded, the consistency of the two methods was good for males (Kappa=0.952) but still poor for females (Kappa=0.194). The most common mutations were c.1376G>T, c.1388G>A and c.95A>G. No G6PD deficiency was found among those only carrying the c.1311C>T mutation. CONCLUSION Flow-through hybridization can simultaneously detect 14 loci, covering over 90% of common mutations in Chinese population, and can be easily expanded. The routine method may miss many females carrying homozygous, compound heterozygous and heterozygous mutations, but the detection rate for male hemizygous mutation was much higher.

A method of ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry ( UPLC-Q-TOF MS) was developed to determine 35 kinds of illegally added chemical fungicides in pesticide formulations. The samples were pretreated based on the ultrasonic extraction by the solvent of methanol, and then separated on a Zorbax C18(100 mm×1. 8 mm, 2. 1 μm) column by a gradient elution with 0. 1% formic acid aqueous solution and acetonitrile as the mobile phase. The mass spectrometer was operated under positive mode. Under the optimal conditions, the recoveries at three spiked levels (0. 2, 0. 4, and 2. 0 mg/kg) were in the range of 81. 0%-101. 3% and the RSDs were 1. 0%-4. 4%. Based on the developed method, 100 samples were analyzed, and among which 6 samples were screened out chemical fungicides. The proposed method was high-efficient, accurate and reliable for the qualitatively screening of illegaly added chemical fungicides.

AIM To explore the effects of glycyrrhetinic acid on the gastric ulcer rats infected by Helicobacter pylori (Hp) and its action mechanism.METHODS Gastric ulcer rat models were induced by acetic acid stress and then followed by Hp infection.After treatment with low and high doses of glycyrrhetinic acid,the ulcer index,gastric acid and proteinase activities in gastric ulcer rats were analyzed.The effects of glycyrrhetinic acid on the expressions of BCL2 and Caspase-3,the GSK3β activity in gastric mucosa and gastric epithelial cells,and the cell apoptosis level were then detected.RESULTS Glycyrrhetinic acid reduced the ulcer index,gastric acid and proteinase activities in rats.Besides,the expression of BCL2 was significantly up-regulated by glycyrrhetinic acid in gastric mucosa and gastric epithelial cells,whereas the expression of Caspase-3,level of cell apoptosis,and GSK3β activity were significantly reduced.After the treatment with GSK3 β activator LY294002,the level of BCL2 was down-regulated,Caspase-3 expression was increased,and the level of cell apoptosis was enhanced.CONCLUSION Glycyrrhetinic acid promotes the healing of gastric ulcer infected by Hp via regulating GSK3β activity and inhibiting apoptosis of gastric epithelial cells.

Objective To establish the characteristic spectrum of ginkgo leaf tablets,ginkgo leaf capsules,and ginkgo leaf dropping pills.Methods HPLC-ELSD analysis was performed on an Agilent Poroshell 120 EC-C18 column(150 mm×4.6 mm,2.7 μm)with the methanol-0.1% formic acid as mobile phase at the gradient elution mode,flow rate was 0.8 mL·min-1.Results Referring to the reference extract,a total of 12 peaks were established in the characteristic spectrum and selected as the characteristic common peaks.Conclusion The established method was simple and sensitive with good reproducibility,so it could be used to control the quality of ginkgo leaf preparations.

Objective To understand the prevalence of hypercholesterolemia and related risk factors in residents aged 18-65 years in Beijing and provide scientific evidence for the prevention and control of hypercholesterolemia.Methods The data were collected from Beijing Non-communicable and Chronic Disease Survey and stratified cluster sampling method was used to select study subjects,and questionnaire investigation,physical measurement and laboratory examination were conducted to collect information.Results The prevalence of hypercholesterolemia and borderline hypercholesterolemia was 6.26％ and 21.34％ respectively in 17 662 residents surveyed,the average total cholesterol level was (4.69 ± 0.95) mmol/L.The prevalence of hypercholesterolemia was 6.33％ in men and 6.20％ in women,the difference was not significant (Z=1.64,P=0.10).The prevalence was higher inurban area than in suburb (6.73％ vs.5.59％;Z=-7.27,P＜0.01).The prevalence of hypercholesterolemia increased with age (trend x2=308.85,P＜0.01).The trend was observed in men (trend x2=81.65,P＜0.01),in women (trend x2=318.04,P＜0.01),in urban area (trend x2=201.77,P＜0.01) and in suburb (trend x2=114.65,P＜0.01).Multiple logistic regression showed age,being female (OR=1.23,95％CI:1.04-1.45),overweight (OR=1.56,95％CI:1.34-1.81),obesity (OR=1.82,95％CI:1.54-2.16),smoking (OR=1.24,95％CI:1.03-1.50),alcohol use (OR=1.40,95％CI:1.12-1.75),beef and mutton intake ＞ 1 time per week (OR=1.19,95％CI:1.02-1.39) were risk factors.Conclusion The prevalence of hypercholesterolemia in Beijing was lower than national level,and age,gender,location,BMI,smoking,alcohol use,beef and mutton intake were main influencing factors.

Objective To study the clinical management way for HPV+/papanicolaou (Pap)-during cervical cancer screening.Methods To analyze retrospectively the data from the patients who had loop electrical excision procedure (LEEP) for biopsy confirmed cervical intraepithelial neoplasia (CIN)Ⅱ in Peking University People's Hospital from Jan.2010 to Dec.2014.Results (1) For biopsy confirmed CINⅡ,HPV positive rate was 98.5％ (135/137),Pap test positive [≥atypical squamous cell of undetermined significance (ASCUS)] rate was 69.3％ (95/137),there was significant difference between them (x5=43.32,P＜0.01).(2) For the 42 patients with HPV+/Pap-,whose cytology slides were reviewed again.Among them,the interpretations of there were 16 cases confirmed as the same before,while 26 cases were changed to abnormal (≥ASCUS).Cytology be misdiagnosed was 19.0％ (26/137) at the first review.Among the 26 cases,13 (50.0％) cases were missed for the little amount of abnormal cells,8 (30.8％) cases for mild atypical morphology changed;the other 5 (19.2％) cases missed for stain problems.(3) For the cervical LEEP samples,37 cases of the pathology diagnosis were upgrade to CIN Ⅲ+,among them,2 cases of microinvasive cervical carcinoma,1 case of invasive cancer,34 cases of CIN Ⅲ;37 cases were CINⅠ or no lesion found;63 cases were still CIN Ⅱ.Four to six months later after LEEP,the cytology abnormal rate was 11.7％ (16/137),and the HR-HPV positive rate was 34.3％ (47/137).Conclusions Compared with cytology alone,cytology combined with HPV testing increase the sensitivity of cervical high grade lesion.For the cases of HPV+/Pap-cases,the cytology slides should be reviewed.The quality control of cervical exfoliate sample collection and interpretation should be strengthened.LEEP procedure is not only a treatment method,but also it could provide samples to confirm the diagnosis.
