Standardized training of residents in the department of orthodontics is an important learn-ing stage for stomatology students before carrying out clinical orthodontic diagnosis and treatment work. At present, there are some deficiencies in the standardized training system of the residents in the Department of Orthodontics, such as the single teaching mode, imperfect training items, and unclear evaluation criteria. The department of orthodontics of Stomatology Hospital of Southern Medical University carried on a prelim-inary study on the training pattern of resident doctors in the refinement of the training content, optimizing curriculum design, implementation of tutorial teaching mode, the combination of theoretical study and clini-cal training, regular training evaluation and quantitative assessment indicators. The results showed that the trainees' acceptance and satisfaction were higher, which was beneficial to the improvement of clinical com-prehensive ability of orthodontics.

Objective : To systematically evaluate the incidence of suicide ideation among HIV/AIDS patients in China, so as to provide insights into prevention of suicidal behaviors among HIV/AIDS patients. Methods : All publications pertaining to suicide ideation were jointly retrieved in electronic databases from database creation to May 22, 2022, including CNKI, CMB, Wanfang Data, VIP, PubMed and Web of Science. The quality of literatures was evaluated using the 11 quality indicators for cross-sectional studies recommended by the United States Agency for Healthcare Research and Quality (AHRQ), and a meta-analysis was performed using the software Stata 16.0. The stability of the study results was evaluated using sensitivity analysis, and the publication bias was evaluated using Begg's test. Results : A total of 1 557 publications were screened and 32 literatures covering 12 917 HIV/AIDS patients were included in the final analysis, including 21 Chinese publications and 11 English publications, and 19 high-quality publications and 13 moderate-quality publications. Meta-analysis showed that the incidence of suicide ideation was 30.3% (95%CI: 23.2%-37.4%) among HIV/AIDS patients in China, and subgroup analysis showed higher incidence of suicide ideation in unemployed HIV/AIDS patients than in employed patients (P<0.05). Sensitivity analysis showed stable study results, and Begg's test revealed no significant publication bias. Conclusions The incidence of suicide ideation is 23.2% to 37.4% among HIV/AIDS patients in China. High attention paid to psychological health and early psychological interventions are required to prevent the development of suicide ideation.

Through random sampling,a total of 300 residents of Beijing Changping Ming Tombs Town were selected for home-based questionnaires.The smoking rate of interviewed residents was 21.4％ (53/248).The rate in men (42/125,33.6％ ) was bigber than that in women ( 11/123,8.9％ ).The rate in those with higher education was lower than that in those with lower educational level ( x2 =27.12,P ＜ 0.05 ).The population awareness of tobacco hazards was 80.6％ (200/248).Awareness in smokers was lower than the average awareness of ex-smokers and nonsmokers ( x2 =5.07,P ＜ 0.05 ).The higher the education level,the higher the awareness of tobacco health hazards ( x2 ≈ 19.72,P ＜ 0.05 ).There were differences in awareness among different age groups (x2 =13.37,P ＜ 0.05 ).

The liver in the traditional Chinese medicine (TCM) theory of visceral manifestation has rich connotations. Thestructure and function of liver differed from that of liver in modern recognition. Research on TCM theory has partiallyexplained the liver theory. The function of controlling dispersion of liver was associated with neuro-endocrine-immunesystem, liver sinus endothelial function, and metallothionein, etc. While the activity of storing blood of liver related withblood coagulation factors, anticoagulant and so on. The functional interaction between Zang-organ and Fu-organ maycorrelate with the lung-liver axis and liver-intestine axis. The review summarized the modern explanation on liverfunction in TCM and its relationship with Fu-organs to help the development of TCM basic theory in liver function.

Objective:To explore the relationship between weight change and metabolic control of type 2 diabetic patients after 1 year treatment under the standardized metabolic disease management model.Methods:From November 2017 to November 2021, 950 patients with T2DM in the Standardized Metabolic Management Center of Suzhou Municipal Hospital were recruited in this research, who were divided into normal(BMI 18.5-23.9 kg/m 2), overweight(BMI 24.0-27.9 kg/m 2), and obese(BMI≥28 kg/m 2)groups according to baseline BMI. The metabolic indicators and control rates were compared. The overweight and obese 599 patients were divided into weight reduction(<-3 kg), maintenance(-3-1 kg) and gain(>1 kg)groups according to weight changes by one year, and metabolic indicators and control rates were compared to analyze the influence of weight change on metabolic control of overweight and obese patients. Results:(1) The overweight and obese groups had worse metabolic control at baseline and the obese group was younger. After 1 year, the metabolic indicators of three groups were significantly improved. (2) After 1 year, the metabolic control was better in weight reduction group and worse in weight gain group. The control rates were increased in weight reduction and maintenance groups. (3) For every 1 kg reduction in body weight of overweight and obese patients, blood glucose, blood lipids, blood pressure and comprehensive control rate increased by 1.206, 1.046, 1.069 and 1.107 times, respectively. There was a positive linear relationship between weight reduction and metabolic improvement.Conclusion:Standardized metabolic disease management model promotes metabolic control in type 2 diabetic patients, especially in overweight and obese patients who actively lose weight. In the future we should strengthen the management of overweight and obese patients, enhance self-management ability, and manage body weight scientifically and effectively.

Objective:To investigate the application value of auricular point pressing with beans combined with Chinese medicine for rehabilitation in older adults after total hip arthroplasty.Methods:This is a prospective case-control study. A total of 80 older adult patients with femoral neck fractures who underwent total hip arthroplasty at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from September 2020 to January 2022 were included in this study. These patients were randomly divided into a control group and an observation group, with 40 patients per group. The control group underwent conventional interventions, while the observation group underwent auricular point pressing with beans combined with Chinese medicine. Clinical efficacy was compared between the two groups.Results:The overall response rate in the observation group was 85.00% (34/40), which was significantly higher than 65.0% (26/40) in the control group ( χ2 = 4.27, P = 0.036). Before surgery, there were no significant differences in various indicators between the two groups (all P > 0.05). At 2 weeks after surgery, the hemoglobin level and Harris scores in the observation group were higher than those in the control group ( t = -7.11, -5.81, both P < 0.05). At 1 and 3 days and 2 weeks after surgery, the D-dimer level, prothrombin time, activated partial thrombin time, thrombin time, Visual Analogue Scale score, and Pittsburgh Sleep Quality Index (PSQI) in the observation group were significantly lower than those in the control group (all P < 0.05). At 3 days and 2 weeks after surgery, C-reactive protein, thigh and calf circumference of the affected limb in the observation group were significantly lower than those in the control group ( t = 2.34, 6.85, 4.47, 3.89, 6.63, 4.35, all P < 0.05). After surgery, the time to get off the bed and the length of hospital stay in the observation group were (3.58 ± 2.43) days and (7.14 ± 2.18) days, respectively, which were significantly shorter than (5.47 ± 2.35) days and (9.13 ± 2.14) days in the control group ( t = 3.54, 4.12, both P < 0.001). The incidence of postoperative deep vein thrombosis in the observation group was 5.00% (2/40), which was significantly lower than 10.00% (4/40) in the control group ( χ2 = 0.72, P = 0.396). Conclusion:Auricular point pressing with beans combined with Chinese medicine can promote rapid rehabilitation of older adult patients with femoral neck fractures after total hip arthroplasty.

Objective:To compare two different methods for the harvest of the costal cartilage cortical slice with perichondrium preserved for rhinoplasty patients, and to explore a simple and less invasive method for the costal cartilage cortical slice.Methods:From September 2019 to December 2020, the rhinoplasty patients using the techniques of nasal tip "double arch" stent combined with prosthesis were selected in Shanghai Time Plastic Surgery Hospital, they were randomly divided into observation group and control group. In the observation group, only the cortical slice of costal cartilage with perichondrium was cut and the continuity of costal cartilage was preserved. While in the control group, with the superficial perichondrium preserved, the whole costal cartilage was dissected first, and then pruned it and harvested the cortical slice of costal cartilage with perichondrium. The operation were performed by the same clinicians in both groups. Different variables were compared between the two groups, including the operation time, intraoperative blood loss, length of incision, the degree of chest pain after postoperative 6, 24, 72 h, 1 week, the incidence of intraoperative complications and so on. The severity of chest pain was assessed by visual analogue scale (VAS). The measurement data of the two groups were analyzed by t-test, and the enumeration data were analyzed by χ2 test. Results:For both observation group and the control group, 61 patients were included. In the observation group, there were 3 males (4.9%) and 58 females (95.1%), aged (28.6±5.4) years old, and BMI (21.76±1.65) kg/m 2. In the control group, there were 2 males (3.3%) and 59 females (96.7%), aged (45.8±5.7) years old, and BMI (22.25±1.47) kg/m 2. There were no significant differences in gender composition, age and BMI between the two groups ( P>0.05). The double arch stent of nasal tip could be made by the costal cartilage cortical slices obtained in the two groups. In the control group, two cases of pleural rupture occurred and their prognosis was good after effective treatment, with no complications such as hematoma, infection or pleural injury. In the observation group, there were no complications such as hematoma, infection or pleural injury. The operation time, incision length and intraoperative blood loss in the observation group were significantly lower than those in the control group [(18.54±3.62) min vs. (25.75±3.75) min; (1.68±0.26) cm vs. (2.16±0.32) cm; (16.79±7.86) ml vs. (25.46±8.49) ml; P<0.05]. The VAS score in the observation group was lower than that in the control group after postoperative 6, 24, 72 h, 1 week [(2.76±0.62) vs. (3.87±0.68)scores; (2.37±0.45) vs. (3.12±0.55) scores; (1.76±0.45) vs. (2.57±0.53) scores; (1.17±0.44) vs. (1.85±0.51) scores; P<0.05]. Conclusions:Compared with the conventional method of whole costal cartilage harvest, the method of harvesting the costal cartilaginous cortical slice with the costal perichondrium preserved and preserving the continuity of the costal cartilage can reduce the trauma and bleeding, shorten the operation time, simplify the operation process, and significantly reduce the postoperative chest pain.
