Objective: The aim of this survey is to investigate the oral heath status of the oldsters over 65_year_old in Chengdu of China.Methods: The oral health status, including oral hygiene, caries, periodontal diseases and the tooth loss of 468 elderly individuals over 65 years old were surveyed and analyzed. Results: It was found that all these older individuals brushed their teeth everyday, but most of them had tooth decay, gingivitis and periodontitis. About 7.47% of them were edentulous, and 2.56% of them were half edentulous. The masticatory ability of most of them declined and the chewing ability of them was low. Conclusion: The oral health status of these elderly individuals in Chengdu is poor. It is therefore necessary to improve the health status of this population.

Objective To investigate whether the proportions of Th17/Treg balance were impaired in the peripheral blood of patients in different phases of synovitis acne pustulosis hyperostosis osteitis (SAPHO) syndrome.Methods We studied 22 cases diagnosed as SAPHO syndrome and 11 healthy controls.According to the scores of VAS pain,BASDAI and BASFA,the 22 patients were divided into active group and stable group.By means of flow-cytometry,the frequencies of total and different subsets of Th17 and Treg cells in peripheral blood mononuclear cell of different groups of SAPHO syndrome and healthy controls were studied.The values of Th17/Treg balance were analyzed.The relationship was analyzed with Kruskal-Wallis test,Mann-Whitney test and Pearman's test.Results The mean percentage of Th17 cells was markedly higher in the active group [(2.74±0.25)％] than in the stable group [(1.16±0.09)％] (U=0.000,P＜0.01) and healthy controls [(1.13±0.11)％] (U=0.000,P＜0.01).No differences were found among active group [(2.10±0.20)％],stable group [(2.51±0.20)％] and control group [(2.44±0.22)％] (x2=2.16,P=0.339 4).The ratio of Th17 cells to Treg cells was markedly higher in active group [(1.48±0.25)％] than in the other two groups [(0.47±0.03)％] (U=0.000,P＜0.01).We also found the positive correlation of the ratios of Th17/Treg cells with the values of VAS in SAPHO syndrome patients (r=0.752 7,P＜0.01).Conclusion The results demonstrate that the development of SAPHO syndrome is closely related to the imbalance of systemic Th17/Treg cells,Increased ratio of Th17/Treg cells may be the main factor that cause disease recurrence,and then,lead to the manifestations of high levels of inflammation and joint pain.

Objective:To investigate the effect of autologous fat grafting in hand rejuvenation and to provide effective clinical treatment for the aging hand.Methods:A total of 52 patients received autologous fat grafting in hand. Fat was collected by liposuction from the abdomen or thigh regions utilizing the superwet technique. The harvested fat was washed and injected to the dorsal hand. Standardized photographs were taken before and after the operation, and the patients＇ satisfaction was evaluated.Results:Picture scores between preoperative and postoperative had statistically significant differences ( P<0.01). The majority of patients (75%) were satisfied with their results. All patients were followed up for 6 months with no infection, fat liquefaction, cysts and other complications occurred. Conclusions:This study provides the clinical basis for fat grafting in hand rejuvenation with high satisfactory rates.

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 rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response.Methods:An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated.Results:When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources.Conclusions:There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.
