Since the founding of the People’s Republic of China, remarkable achievements have been gained in infectious disease prevention and control, and rich practical experiences have been accumulated. If these experiences are shared with developing countries, it will greatly contribute to global infectious disease control and global health security. Under the framework of Forum on China-Africa Cooperation, a series of China-Africa public health capacity training programs have been recently held in China, in order to help improve the capability of infectious disease control in African countries. This article summarized and refined good design concepts and practices from these programs, so as to provide insights into sustainable optimization of China-Africa public health capacity training and improvements of the training effectiveness.

ObjectiveTo analyze the characteristics and trends of injury-related deaths among the registered residents in Yuyao City, Zhejiang Province from 2014 to 2023, and to provide a scientific basis for the formulation of targeted injury prevention and control strategies. MethodsData on injury-related deaths in Yuyao City from January 1, 2014 to December 31, 2023 were collected from the cause-of-death surveillance module of the chronic disease monitoring and management system of Zhejiang Province. Indicators including constituent ratio, crude mortality rate (CMR), standardized mortality rate (SMR), premature death probability, potential years of life lost (PYLL), average years of life lost (AYLL), and potential years of life lost rate (PYLLR) were calculated. The average annual percentage change (AAPC) was used to analyze the trends in injury mortality over the past 10-year period. ResultsFrom 2014 to 2023, a total of 6 625 injury-related deaths were reported in Yuyao City, accounting for 10.65% of all deaths and ranking fourth among all causes. The CMR was 79.34/100 000 and showed an increasing trend (AAPC=4.396%, t=2.875, P=0.021), while the SMR was 38.99/100 000 with no significant trend (AAPC=-0.585%, t=-0.451, P=0.664). The SMR of females (37.74/100 000) was lower than that of males (40.87/100 000) (χ²=12.468, P<0.001). The top 5 causes of injury-related death were falls, traffic accidents, drowning, suicide, and accidental suffocation. Over the 10-year period, the SMRs for traffic accidents, drowning, and suicide showed downward trends (AAPC=-5.381%, t=-3.428, P=0.009; AAPC=-8.061%, t=-6.924, P<0.001; AAPC=-6.919%, t=-4.039, P=0.004, respectively), while the SMRs for falls and accidental suffocation showed no significant trends (AAPC=3.417%, t=1.767, P=0.115; AAPC=2.228%, t=0.803, P=0.445). Injury mortality increased with age for males, females, and the total population (all P<0.05). The leading causes of injury-related death were drowning among residents aged 0‒<15 years, traffic accidents among those aged 15‒<45 and 45‒<65 years, and falls among those aged 65‒<85 and 85‒110 years. The total PYLL due to injury was 58 708.00 person-years, the AYLL was 21.23 years, and the PYLLR was 7.36‰. ConclusionFrom 2014 to 2023, the crude mortality rate due to injuries in Yuyao City remained at a relatively high level, posing a serious threat to residents’ health and well-being. Falls, traffic accidents, drowning, suicide, and accidental suffocation are key targets for injury prevention and control work.

OBJECTIVE To explore the mechanism by which Cuscuta chinensis flavonoids （CCF） promote decidualization and improve recurrent spontaneous abortion （RSA）. METHODS HTR-8/SVneo cells in logarithmic growth phase were randomly divided into blank group， lipopolysaccharide （LPS） group， CCF group， SGK2 inhibitor （GSK650394， abbreviated as “GSK”） group and CCF+GSK group. Each group was treated with the corresponding agents accordingly. HTR-8/SVneo cells with SGK2 knockdown were randomly divided into small interfering RNA of SGK2 （siSGK2） group and siSGK2+CCF group； additionally， blank group and LPS group were established； each group was treated with the corresponding agents accordingly. The cell survival rate， expression levels of WNK signaling pathway- and decidualization-related proteins and mRNAs， as well as mitochondrial membrane potential levels， were assessed in each group before and after SGK2 knockdown. RSA mice model was constructed and randomly divided into model group， CCF low-dose group， CCF high-dose group， GSK group， and combined dosing group， with 4 mice in each group. Other 4 normal pregnant female mice were selected as the control group. The number of implanted embryos， viable fetuses， and lost embryos in mice was recorded. The morphological changes of endometrium and decidualization were observed， and WNK signaling pathway- and decidualization-related proteins and mRNAs expressing levels as well as mitochondrial membrane potential levels were all detected. RESULTS Compared with the blank group， the cell survival rate， as well as the protein and mRNA expression levels of SGK2， WNK1， WNK4， prolactin， insulin-like growth factor- binding protein-1， oxidative stress responsive kinase 1， and Ste20-like proline-/alanine-rich kinase were significantly reduced in the LPS group （P＜0.05）； compared with the LPS group， the cell survival rate and the expression levels of the above- mentioned proteins and mRNAs were significantly increased in the CCF group， while the cell survival rate and the expression levels of the above-mentioned proteins and mRNAs were significantly decreased in the GSK group （P＜0.05）； compared with the CCF group， the cell survival rate and the expression levels of the above-mentioned proteins and mRNAs were significantly reduced in the CCF+GSK group （P＜0.05）. After knocking down SGK2， compared with the LPS group， the cell survival rate， red/green fluorescence intensity ratio， and the expression levels of the above-mentioned proteins and mRNAs were significantly reduced in the siSGK2 group （P＜0.05）； compared with the siSGK2 group， the cell survival rate， red/green fluorescence intensity ratio， and the expression levels of the above-mentioned proteins and mRNAs were significantly increased in the siSGK2+CCF group （P＜0.05）. The in vivo experimental results showed that CCF treatment can significantly improve the number of implanted embryos and viable fetuses in RSA model mice and reduce lost embryos， the expression levels of the above-mentioned proteins and mRNAs in endometrial tissue were significantly increased， and the red/green fluorescence intensity ratio was significantly increased （P＜ 0.05）； the combined dosing group could reverse the effect of CCF （P＜0.05）. CONCLUSIONS CCF can activate SGK2， up- regulate the WNK signaling pathway， promote endometrial decidualization， and improve RSA.

Protrusive facial deformities, characterized by the forward displacement of the teeth and/or jaws beyond the normal range, affect a considerable portion of the population. The manifestations and morphological mechanisms of protrusive facial deformities are complex and diverse, requiring orthodontists to possess a high level of theoretical knowledge and practical experience in the relevant orthodontic field. To further optimize the correction of protrusive facial deformities, this consensus proposes that the morphological mechanisms and diagnosis of protrusive facial deformities should be analyzed and judged from multiple dimensions and factors to accurately formulate treatment plans. It emphasizes the use of orthodontic strategies, including jaw growth modification, tooth extraction or non-extraction for anterior teeth retraction, and maxillofacial vertical control. These strategies aim to reduce anterior teeth and lip protrusion, increase chin prominence, harmonize nasolabial and chin-lip relationships, and improve the facial profile of patients with protrusive facial deformities. For severe skeletal protrusive facial deformities, orthodontic-orthognathic combined treatment may be suggested. This consensus summarizes the theoretical knowledge and clinical experience of numerous renowned oral experts nationwide, offering reference strategies for the correction of protrusive facial deformities.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.
