Objective:To investigate the awareness of diabetes knowledge among the health examination population and its influencing factors.Methods:A cross-sectional study. From september to november 2022, the subjects of six health examination centers located in six different cities (Beijing, Shanghai, Tianjin, Chongqing, Xiamen, Hangzhou) in China were investigated in the form of questionnaires to investigate the awareness of diabetes core information and the level of trust to different information sources of diabetes knowledge. According to the questionnaire results, the subjects were divided into a high awareness group of diabetes core information and a low awareness group. Logistic regression was used to analyze the influencing factors of diabetes core information awareness; the t-test was used to compare the trust degree of the two groups to different information sources. Results:A total of 9 315 people were included in the six centers, including 4 932 men (52.90%) with an average age of (39.36±12.64) years and 4 383 women (47.10%) with a mean age of (37.47±11.85) years. Only 36% of the people had high awareness of diabetes core information; variables such as gender, age, education level, physical examination frequency in the past three years, package price of this physical examination, self-evaluation of diabetes knowledge, diabetes status, and city of residence were variables that affect the level of awareness of core information related to diabetes (all P<0.05). Compared with the low awareness group of diabetes core information, the high awareness group trusted professional medical staff ( t=-9.597, P<0.05) and community health promotion more ( t=-5.014, P<0.05), but did not trust the emerging popular science propaganda means, such as WeChat official accounts/WeChat groups/QQ groups, Internet web page, Tiktok/Kwai and other short video APPs. Conclusion:The awareness rate of diabetes knowledge among the health examination population is low, and it is affected by many factors; Health education on diabetes knowledge should be carried out for people undergoing physical examination.

BACKGROUND: Weather conditions are a possible contributing factor to age-related macular degeneration (AMD), a leading cause of irreversible loss of vision. The present study evaluated the joint effects of meteorological factors and fine particulate matter (PM_2.5) on AMD. METHODS: Data was extracted from a national cross-sectional survey conducted across 10 provinces in rural China. A total of 36,081 participants aged 40 and older were recruited. AMD was diagnosed clinically by slit-lamp ophthalmoscopy, fundus photography, and spectral domain optical coherence tomography (OCT). Meteorological data were calculated by European Centre for Medium-Range Weather Forecasts (ECMWF) reanalysis and were matched to participants' home addresses by latitude and longitude. Participants' individual PM_2.5 exposure concentrations were calculated by a satellite-based model at a 1-km resolution level. Multivariable-adjusted logistic regression models paired with interaction analysis were performed to investigate the joint effects of meteorological factors and PM_2.5 on AMD. RESULTS: The prevalence of AMD in the study population was 2.6% (95% CI 2.42-2.76%). The average annual PM_2.5 level during the study period was 63.1 ± 15.3 µg/m³. A significant positive association was detected between AMD and PM_2.5 level, temperature (T), and relative humidity (RH), in both the independent and the combined effect models. For PM_2.5, compared with the lowest quartile, the odds ratios (ORs) with 95% confidence intervals (CIs) across increasing quartiles were 0.828 (0.674,1.018), 1.105 (0.799,1.528), and 2.602 (1.516,4.468). Positive associations were observed between AMD and temperature, with ORs (95% CI) of 1.625 (1.059,2.494), 1.619 (1.026,2.553), and 3.276 (1.841,5.830), across increasing quartiles. In the interaction analysis, the estimated relative excess risk due to interaction (RERI) and the attributable proportion (AP) for combined atmospheric pressure and PM_2.5 was 0.864 (0.586,1.141) and 1.180 (0.768,1.592), respectively, indicating a synergistic effect between PM_2.5 and atmospheric pressure. CONCLUSIONS This study is among the first to characterize the coordinated effects of meteorological factors and PM_2.5 on AMD. The findings warrant further investigation to elucidate the relationship between ambient environment and AMD.

Radiotherapy, as a common modality for the treatment of head and neck cancer (HNC), frequently induces oral and maxillofacial complications. However, the complex tissues and diverse pathogeneses of these regions lead to limited treatment protocols and research progress currently. This paper systematically summarizes radiation-induced oral mucositis, salivary gland injury, and dental caries in radiotherapy for HNC and reviews existing pathogenetic hypotheses, treatment, and research progress. The purpose is to provide some reference for further research on relevant pathological mechanisms and the development of new preventive and treatment methods.

Objective:To explore the clinical effects of combined medial and lateral approaches in treating of calcaneal fractures combined with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint.Methods:Four adult cadaver specimens (8 feet) were selected, of which two (4 feet) were dissected on the medial side of the calcaneus to observe the adjacency and exposure range of sustentaculum tali. The other two specimens were simulated as medial and lateral approaches to reduce and fix calcaneal fractures. Retrospective analysis of 9 cases (9 feet) of Sanders II-IV type calcaneal fractures with combined medial and lateral approaches in the treatment of fractures and/or dislocations of sustentaculum tali-talus joint was performed. The average age was 49.9±11.3 (25-58) years. During the operation, the medial incision was made first, and the sustentaculum tali fracture was temporarily reduced and fixed to the talus. Then the lateral incision was made to expose the lateral side of the calcaneus, and the fracture fragments were reduced and fixed; the sustentaculum tali was fixed laterally with screws, and 2 cases were additionally fixed medially with absorbable rods. At the same time, six cases (8 feet) of calcaneal fractures with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus were treated with lateral approach as a control group. The lateral sides of both groups were fixed with calcaneal locking plate and implanted with demineralized bone matrix into the cavity after articular surface reduction. The B?hler and Gissane angles of the two groups of patients were measured at 1 year after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used to evaluate the clinical efficacy.Results:The sustentaculum tali-talus joint had a shape of an inverted "V" with two divided parts. The tip of the sustentaculum tali was exposed through the front window of the posterior tibial tendon. The sustentaculum tali and the medial side of the calcaneal body was completely exposed and fixed through the window between the posterior tibial tendon and the flexor digitorum longus tendon. The postoperative incision blood loss in the combined medial and lateral approach group was 73.6±4.3 ml, which was greater than that in the lateral approach group (70.6±7.1 ml) ( t=2.18, P=0.045). The lateral incision healed in both groups. The medial incision healed delayed in 1 patient in the combined medial and lateral approach group. The fractures in the combined medial-lateral approach group and the lateral approach group were both healed. The healing duration was 12.2±2.1 weeks and 12.8±2.8 weeks, respectively, without significant difference ( t=0.50, P=0.622). The B?hler angles of the combined medial-lateral approach group and the lateral approach group were 37.0°±5.7° and 27.9°±4.0° at 1 year after operation, respectively. These values were greater than the preoperative values of 4.7°±3.4° and 3.9°±2.9° ( P<0.05), with significant difference between groups ( t=3.76, P=0.002). The Gissane angles were 133.2°±9.8° and 139.1°±9.4° respectively, which were lower than those of 172°±7.3° and 175.6°±5.6° before operation ( P<0.05). There was no significant difference between the groups ( t=1.26, P=0.226). The AOFAS score of the combined medial and lateral approach group was 93.6±4.0 points, which was higher than that of the lateral approach group (84.3±8.2 points) ( t=3.03, P=0.008). Conclusion:Intra-articular calcaneal fractures combined with a high probability of sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint. Compared with the simple lateral approach, the use of the combined medial-lateral approach and the medial-lateral surgical sequence is beneficial to restore the calcaneal alignment and anatomic shape, especially the alignment relationship of the medial calcaneus and talus, so as to obstain better early clinical outcomes.

Objective:To explore the clinical effect of the composite reduction labiaplasty by divisional design.Methods:From January 2020 to February 2022, the clinical data of patients with complex labia minora and clitoris prepuce hypertrophy who were treated in the Medical Cosmetic Center of Beijing Friendship Hospital Affiliated to Capital Medical University were collected and analysed. The inner side of their labia minora showed no chalasis in the vertical direction, but the outer side were slack with folds, accompanied by clitoris prepuce hyperplasia. We adopted the composite reduction labiaplasty by divisional design. The outer side of the labia minora and the clitoral prepuce were considered as a whole, and a wedge-shaped incision line was designed to remove the excess tissue in the vertical direction. On this basis, an arc was projected on the inner side of the labia minora to form an arcuate incision line on the inner side. The composite reduction labiaplasty was performed with the combination of wedge resection and edge resection. The postoperative follow-up observations included: postoperative complications, the symmetry of the labia minora and clitoris prepuce, the improvement of frictional discomfort, the cleanliness of the labia minora and the clitoris prepuce, and the patient's satisfaction with the shape of the labia minora and clitoris prepuce. For patients with sexual experience, follow-up content also includes changes in sexual satisfaction.Results:A total of 17 female patients aged 20 to 35 years, with an average age of 27 years, were included in this study. Follow-up was conducted 2 months after the operation. All incisions healed by first intention with no sawtooth-like deformity at the incision margin, and had natural appearance. Patients felt that the bilateral labia minora and clitoral foreskin were completely symmetrical in 3 cases, basically symmetrical in 12 cases, and partially asymmetric in 2 cases. These 2 cases of partial asymmetry did not require further surgical repair. In all 17 patients, the frictional discomfort was completely resolved, and the labia minora and clitoral foreskin were easier to clean. The patients were very satisfied with the appearance in 5 cases, satisfied in 10 cases, and dissatisfied in 2 case. There were 15 patients with previous sexual life experience, of which 10 patients had improved sexual satisfaction, and 5 patients had no change in sexual satisfaction after the operation.Conclusions:Through the divisional design, wedge resection and edge resection are performed in the composite reduction labiaplasty, which can solve the friction and discomfort caused by the hyperplasia of labia minora and clitoris prepuce in a single operation, and achieve better aesthetic results at the same time.

Objective: To explore clinical efficacy and safety of Wumeiwan combined with triple therapy for treatment of chronic atrophic gastritis (CAG). Methods: According to the random indicator method, 113 patients with CAG were divided into control group (n=56) and treatment group (n=57). Patients of control group were treated with triple therapy, while treatment groupwere treated Wumeiwan combined with triple therapy. The two groups were treated for 3 months. Clinical effect was evaluated after treatment. The helicobacter pylori (Hp) conversion to negative of the two groups was compared and recorded. The Hp overcast conditions of the two groups were compared. The serum TNF-α, IL-6, IL-8 and peripheral blood CD3⁺, CD4⁺, CD8⁺, CD4⁺/CD8⁺ of the two groups before and after treatment were compared. The adverse reactions of the two groups during the treatment were compared. Results: Total effective rate of treatment group was 94.7% (54/57), which was significantly higher than the control group 82.14% (46/56), and the difference was statistically significant (χ²=4.401, P=0.036). Hp overcast rate of treatment group was 88.2% (45/51), which was significantly higher than the control group 48.0%(24/50), and the difference was statistically significant (χ²=18.883, P=0.000). After treatment, the serum TNF-α (1.43 ± 0.17 mg/L vs. 1.97 ± 0.22 mg/L, t=14.615), IL-6 (30.79 ± 3.65 ng/L vs. 41.13 ± 4.10 ng/L, t=14.166), IL-8 (7.52 ± 1.32 ng/L vs. 9.60 ± 1.77 ng/L, t=7.090) in the treatment group were lower than those in the control group (P<0.05). After treatment, the peripheral blood CD3⁺ (75.12% ± 16.44% vs. 67.33% ± 14.37%, t=2.680), CD4⁺ (39.02% ± 11.41% vs. 33.49% ± 10.61%, t=2.667), CD4⁺/CD8⁺ (1.58 ± 0.35 vs. 1.19 ± 0.32, t=6.179) in the treatment group were higher than those in the control group (P<0.05), the peripheral blood CD8⁺ (24.75% ± 9.69% vs. 28.12% ± 11.29%, t=1.704) in the treatment group were higher than those in the control group (P<0.05). There was no significantly difference of the adverse reaction rates of the two groups during treatment (χ²=0.134, P=0.714).
