Objective: Miniscrews are commonly utilized as temporary anchorage devices (TADs) in cases of maxillary protrusion and premolar extraction. This study aimed to investigate the effects and potential side effects of two conventional miniscrew configurations on the maxillary incisors. Methods: Eighty-two adult patients with maxillary dentoalveolar protrusion who had undergone bilateral first premolar extraction were retrospectively divided into three groups: non-TAD, two posterior miniscrews only (P-TADs), and two anterior and two posterior miniscrews combined (AP-TADs). Cone-beam computed tomography was used to evaluate the maxillary central incisors (U1). Results: The APTADs group had significantly greater U1 intrusion (1.99 ± 2.37 mm, n = 50) and less retroclination (1.70° ± 8.80°) compared to the P-TADs (–0.07 ± 1.65 mm and 9.45° ± 10.68°, n = 60) and non-TAD group (0.30 ± 1.61 mm and 1.91° ± 9.39°, n = 54).However, the AP-TADs group suffered from significantly greater apical root resorption (ARR) of U1 (2.69 ± 1.38 mm) than the P-TADs (1.63 ± 1.46 mm) and non-TAD group (0.89 ± 0.97 mm). Notably, the incidence of grade IV ARR was 16.6% in the AP-TADs group, significantly higher than the rates observed in the P-TADs (6.7%) and non-TAD (1.9%) groups. Multiple regression analysis revealed that after excluding tooth movement factors, the AP-TADs configuration resulted in an additional 0.5 mm of ARR compared with the P-TADs group. Conclusions In cases of maxillary protrusion and premolar extraction, the use of combined anterior and posterior miniscrews enhances incisor intrusion and minimizes torque loss of the maxillary incisors. However, this approach results in more severe ARR, likely due to the increased apical movement and composite force exerted.

The Healthy China 2030 Plan set the goal of reducing premature deaths from diabetes by 30% by 2030. However, there has been a lack of assessment of premature mortality for diabetes since the action plan was issued. This study used data from the Global Burden of Disease Study 2021, calculated the premature deaths for diabetes by sex, provinces, and subtypes from 1990 to 2021. We explored the temporal trend of premature mortality using the average annual percent change (AAPC) for different sexes, provinces, and subtypes from 1990 to 2021. Furthermore, we predicted premature mortality for diabetes through 2030 for China and its provinces according to the average annual change rate from 2010 to 2021. There was a first slow upward trend in premature mortality for diabetes from 0.5% in 1990 to 0.6% in 2004, and then a decline until 2021 with premature mortality of 0.4%. By 2030, only Fujian (30.3%) will achieve the desired level of reduction, with only seven provinces meeting the target for females and none for males. There is a large range in the degree of decline between inland and coastal regions, showing obvious geographic differences, and there should be a focus on balancing medical resources.

In orthodontic treatment for protrusion,premolar extraction is a common option.The extraction spaces are closed by the re-ciprocal movement of posterior and anterior teeth.However,the unclear question is,after extracting the first or second premolars in the maxilla or mandible,what amount is the"anchorage loss"(mesial movement)of the molars when the spaces closed using intra-arch re-ciprocal anchorage only.We reviewed a large number of clinical studies on orthodontic treatment involving the extraction of premolars to investigate the factors related to molar anchorage loss.Existing studies have explored the influence of physiological factors such as age,occlusal relationship,and vertical facial profile,as well as treatment factors such as tooth extraction site,appliance system,and gap closure method on the molar anchorage loss in orthodontic cases involving the extraction of premolars.The reported molar anchorage loss under different conditions has certain reference value for the orthodontic extraction plan making and anchorage design.More high-quality clinical studies are needed to further clarify this important clinical issue in the future.

Objective To investigate the role of cardiac rehabilitation program in the early recovery after minimally invasive incision coronary artery bypass grafting with general anesthesia. Methods A retrospective study was performed on the patients who underwent minimally invasive incision coronary artery bypass grafting from January 2015 to January 2020 with general anesthesia in our hospital. The patients were divided into a cardiac rehabilitation group and a control group. The clinical data of the patients were collected in 6 months and 12 months after the beginning of cardiac rehabilitation program and were analyzed by propensity score-matching analysis with a ratio of 1∶1. The main outcomes were the peak oxygen uptake (VO2 peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialties in tertiary hospitals during the follow-up period (20 months). Results A total of 600 patients were enrolled, including 200 patients in the cardiac rehabilitation group [137 males and 63 females, aged 61.00 (56.00, 65.00) years] and 400 patients in the control group [285 males and 115 females, aged 60.00 (56.00, 65.00) years]. After matching, 176 patients were included in each group, and the basical clinical data of the pateints were comparable (P>0.05). The VO2 peak of the cardiac rehabilitation group after 6 months and 12 months of cardiac rehabilitation was significantly different from that of the control group [6 months: 1.96 (1.59, 2.38) L/min vs. 1.72 (1.38, 2.12) L/min, P<0.001; 12 months: 2.40 (2.21, 2.63) L/min vs. 2.12 (1.83, 2.45) L/min, P<0.001]. During the follow-up period, there was a statistical difference in the cardiovascular specialist visits in tertiary hospitals (P=0.004). Conclusion Cardiac rehabilitation program has a positive effect on the recovery of minimally invasive incision coronary artery bypass grafting with general anesthesia, and can improve the exercise ability of patients.

Objective To investigate the epidemiological characteristics of foodborne diseases in Liuzhou City, and to provide reference for formulating the prevention and control measures of foodborne diseases. Methods The surveillance data of foodborne diseases in 25 sentinel hospitals in Liuzhou City from 2018 to 2020 were collected for statistical analysis. Results From 2018 to 2020, a total of 9 317 cases of foodborne diseases were reported in Liuzhou City, and 2 158 samples were collected for pathogen detection. A total of 311 cases were detected positive , with a detection rate of 14.41%. Norovirus had the highest detection rate (8.63%), followed by Salmonella (4.08%) and Escherichia coli (3.10%). July to October was a period of high incidence of foodborne disease（ 41.17%）. The proportion of patients aged 60 and over was the highest (18.49%), followed by the age group of 30-39 (18.03%). Suspicious foods were mainly meat and meat products (22.35%) and aquatic animals and their products (13.89%). The suspicious eating places were mainly families (40.43%) and restaurants (13.63%). Conclusion The high incidence of foodborne diseases in Liuzhou occurs in summer and autumn. The main pathogens are Salmonella and norovirus. Infected patients are concentrated in the age group of 60 years and above and the age group of 30 to 39 years old. The family is the main place of foodborne disease, followed by the restaurants and hotels. Suspicious foods include mainly meat and meat products and aquatic animals and their products. It is necessary to strengthen monitoring ability and food safety education to reduce the occurrence of foodborne diseases.

Objective:To investigate short-term safety, efficacy and the learning curve of this self-developed novel transcatheter valve repair system (Neonova?) in patients with mitral regurgitation, and explore the role of perioperative echocardiography.Methods:Ten patients who visited the Union Hospital of Tongji Medical College, Huazhong University of Science and Technology from June 2021 to March 2022 and met the inclusive criteria were prospectively enrolled. All the patients were at high risk of surgery with moderate to severe or severe mitral regurgitation (MR). Clamps of Neonova? were implanted under guidance of transesophageal echocardiography and digital subtraction angiography. Clinical outcomes, echocardiography indexes and learning curves of this technique were evaluated immediately after intervention, 7 d, 1 month and 3 months post-intervention.Results:The technical success rate was 100% with MR relieved in all patients immediately after intervention. The device and procedural success rates were both 90.0% with 1 patient received surgical replacement at 37 days post-intervention while the others′ reduced to mild (8/9) and moderate (1/9) MR. New York Heart Association class and the Kansas City Cardiomyopathy Questionnaire improved significantly (all P<0.001). Mean mitral valve pressure gradient didn′t increase significantly after intervention when compared with that before intervention( P=0.324), and no mitral stenosis was observed. Left ventricular end-diastolic diameter decreased significantly ( P=0.008) during follow up.Procedure duration ranged from 60 to 300 (175.8±75.2)minutes. The simple linear regression model between procedure volume and duration showed that procedure duration decreased significantly with the increase of procedure volume ( F=15.857, P=0.004). Conclusions:Neonova? implantation can improve MR severity and clinical symptoms safely and effectively. Transthoracic echocardiography and transesophageal echocardiography are essential for perioperative management of transcatheter mitral valve repair.
