Objective: To compare the intervention effects of sitagliptin combined with metformin and insulin aspart combined with metformin among patients with type 2 diabetes mellitus (T2DM), so as to provide the reference for optimizing blood glucose control strategies among patients with T2DM. Methods: T2DM patients admitted to the department of endocrinology of Jinhua Central Hospital from January 2018 to December 2024 were selected as the research objects. According to the propensity score matching, T2DM patients were divided into sitagliptin combined with metformin group and insulin aspart combined with metformin group at a ratio of 1∶1. The basic information, capillary blood glucose, glycosylated hemoglobin blood glucose (HbA1c), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG), body mass index (BMI), systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the two groups were collected by questionnaire survey, physical examination and laboratory test. The generalized estimating equation was used to analyze the changes of various indicators before and after treatment between the two groups of patients, and the intervention effect was compared. Results: There were 69 cases in the sitagliptin combined with metformin group. Among these 42 cases were males, accounting for 60.87%, and 27 cases were females, accounting for 39.13%.Forty-two cases were younger than 60 years, accounting for 60.87%. There were 69 cases in the insulin aspart combined with metformin group. Among these 47 cases were males, accounting for 68.12%, and 22 cases were females, accounting for 31.88%. Forty-five cases were younger than 60 years, accounting for 65.22%. There were no statistically significant differences in gender, age, education level, smoking, drinking, vegetable and fruit intake, and disease duration between the two groups (all P>0.05). After 6 months of treatment, there was an interaction between group and time in capillary blood glucose and HbA1c in the two groups (all P<0.05), and the reduction of capillary blood glucose and HbA1c in the sitagliptin combined with metformin group was greater than that in the insulin aspart combined with metformin group. There were no statistically significant differences between groups and time in TC, HDL-C, TG, BMI, SBP, and DBP, and no interaction effect was found between groups and time (all P>0.05). Conclusion Sitagliptin combined with metformin is more effective than insulin aspart combined with metformin in controlling blood glucose among patients with T2DM.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To develop an indicator system for defining the health services provided by family doctors within the "Healthy Subdistrict" initiative in China.Methods:An initial set of indicators was developed through literature review and qualitative research, followed by the design of an expert consultation questionnaire. Twenty-one experts with extensive experience in community family doctor services in Beijing were selected. Two rounds of Delphi consultations were conducted via email between December 2024 and February 2025. Expert demographics and authority coefficients were collected and the indicator system was finalized.Results:The response rate was 100% for both rounds. The average expert authority coefficient ( Cr) was 0.860 (range: 0.700-1.000). Kendall′s W for importance and feasibility increased from 0.129 and 0.196 in the first round to 0.230 and 0.268 in the second round (all P<0.001), indicating strong consensus. The final system includes 5 first-level and 23 second-level indicators, categorized as: Integrated Preventive and Clinical Care Services, Healthy Community Promotion Services, Basic Medical Services, Public Health Services, and Services for Promoting Equity in Citizen Health and Well-being. The highest-weighted first-level indicators were Basic Medical Services (0.281) and Integrated Preventive and Clinical Care Services (0.281), followed by Services for Promoting Equity in Citizen Health and Well-being (0.191), Healthy Community Promotion Services (0.124), and Public Health Services (0.124). All indicators had importance and feasibility scores above 3.5. Conclusion:This study establishes a weighted indicator system to guide and evaluate the health services provided by family doctors within the "Healthy Subdistrict" initiative, clarifying key service priorities.

Objective:To determine the optimal irradiation energy and frequency for the establishment of melasma mouse model using simple ultraviolet irradiation, and to provide guidance on animal strains and irradiation protocols for the successful establishment of melasma model.Methods:Animal models of melasma were established using BALB/c female mice and C57BL/6JNifdc female mice. BALB/c female mice were divided into 4 groups using a simple randomization method: A, B, C and G, with 5 mice in each group. C57BL/6JNifdc female mice were divided into 4 groups: D, E, F and H, with 5 mice in each group. All mice were irradiated with 8.428 mW/cm 2 of ultraviolet light. The irradiation time was 15 s (single irradiation energy of 0.13 J/cm 2) in groups A and D, 15 min (single irradiation energy of 7.59 J/cm 2) in groups B and E, and 30 min (single irradiation energy of 15.17 J/cm 2) in groups C and F. Each cycle consisted of 5 consecutive days of irradiation followed by 2 days of cessation, totaling 4 cycles of irradiation. Groups G and H were not irradiated. At the end of irradiation, all mice were kept under normal conditions. One week later, 3 mice from each group were selected for HE, Masson-Fontana, Masson, and immunohistochemical staining. Quantitative analysis was performed to measure the thickness of the acanthocyte layer, melanin granules, collagen percentage, and interleukin-1 (IL-1) levels. The remaining mice were kept for an additional week, depilated and photographed to observe the changes in coloration. Data were analyzed using SPSS 27.0 software, measurement data that did not conform to normal distribution were represented by M( Q1, Q3) and comparisons between groups were made using the Kruskal-Wallis rank sum test. Results:During the entire irradiation process, no visible discoloration was observed in the BALB/c female mice in all groups. In contrast, varying sizes of discoloration appeared in the C57BL/6JNifdc female mice in groups D, E, and F after irradiation in the second week. However, by the third week, the discoloration in group D gradually disappeared, while the discoloration in group E was more obvious than before. At the same time, group F exhibited significant discoloration, with some mice exhibited signs of skin peeling, burning and breakage on their backs. After the 4th week of irradiation, no new discoloration was formed in group D. The discoloration was more obvious in group E, and most mice in group F showed skin burn breakage. Two weeks after the completion of irradiation, there was no obvious discoloration on the dorsal skin of BALB/c female mice in all groups. In C57BL/6JNifdc female mice, group D showed no obvious discoloration, group E exhibited lighter discoloration compared to the 4th week post-irradiation, and group F had crusted skin at the burn sites with lighter discoloration than before. However, the discoloration in groups E and F was still obviously visible to the naked eye. HE staining showed that the difference in the thickness of the echinocyte layer was not statistically significant in groups A, B, C, and G ( H=1.08, P=0.782); whereas the difference was statistically significant in groups D, E, F and H ( H=12.85, P=0.005). The thickness of the echinocyte layer decreased gradually with the extension of the irradiation time. Additionally, there was a disruption in the arrangement of epidermal spindles in group F, and this situation was not observed in groups D and E. Masson-Fontana staining revealed no significant pigmentation in any of the BALB/c female mice. The difference in melanin granule counts between groups A, B, C, and G was not statistically significant ( H=7.77, P=0.051). In contrast, C57BL/6JNifdc female mice exhibited more noticeable pigmentation in the epidermis and dermis in groups E and F. The difference in melanin particle counts among groups D, E, F and H was statistically significant ( H=17.61, P<0.001), with melanin deposition increasing gradually with the duration of irradiation. Masson staining showed that the difference in collagen percentage between groups A, B, C, and G was not statistically significant ( H=7.26, P=0.064). However, significant disorganization of fibers and a loose structure were observed in groups E and F. The difference in collagen percentage between groups D, E, F, and H was statistically significant ( H=8.65, P=0.034). Immunohistochemical results showed that the difference in IL-1 expression levels between groups A, B, C, and G was statistically significant ( H=17.86, P<0.001); also between groups D, E, F, and H was statistically significant ( H=14.19, P=0.003), suggesting that ultraviolet irradiation stimulated an inflammatory response in the skin of mice. Conclusion:BALB/c female mice are not suitable for melasma models under the frequency and duration of irradiation in this experiment. C57BL/6JNifdc female mice are irradiated with a single irradiation energy dose of 7.59 J/cm 2 five days a week for 4 weeks, which can establish stable animal models of melasma with a specific level of pigmentation that persisted for at least 2 weeks.

Objective:To explore the key copy number variation (CNV) regions, abortion candidate genes and signaling pathways associated with recurrent spontaneous abortion (RSA).Methods:A retrospective cohort study was conducted based on the data of 1 870 miscarriage cases of RSA patients who received CNV analysis by high-throughput sequencing technology in the Laboratory Medicine Department of the Third Affiliated Hospital of Zhengzhou University from January 2016 to September 2022. These cases were divided into different groups based on the age of miscarriage and gestational age of the pregnant women. Chi-square test or Fisher's exact test was used to analyze the distribution of chromosome abnormalities and CNV. Gene functions and signaling pathways in RSA-related CNV were identified by gene enrichment analysis.Results:Among the 1 870 tissues, 1 001 (53.53%) cases were detected with chromosomal abnormalities. A total of 140 CNVs were detected in 93 tissues (9.29%), including 34 submicroscopic CNVs (segment<10 Mb) and 106 large CNVs with segment≥10 Mb. Submicroscopic pathogenicity CNVs with statistical differences were involved 1p36.33p36.23, 2q37.3, 4p16.3, 22q11.21 (χ 2=6.99, P=0.008) in early RSA embryos (≤12 weeks). 16p11.2 and Xp11.23p11.22 microdeletion were firstly reported in abortion cases. Significantly recurrent large CNVs were mainly involved 18q22q23 (del/dup), 4p16p15, 9p24p22, 8p23p22, and Xp22.3 regions, and the candidate genes mainly concentrated on PI3K-Akt and JAK-STAT signaling pathway. Conclusion:Rare submicroscopic CNVs and recurrent large CNVs were associated with RSA in early pregnancy. GO and KEGG database analysis revealed potential abortion candidate genes and signaling pathways, providing new information for the genetic etiology of RSA.
