Objective To investigate the prevalence and pattern of androgenetic alopecia (AGA) in Shanghai through a community-based survey. Methods A cluster sampling survey was done among the residents in Beixinjing Community, Changning District, Shanghai. All the subjects were asked to fill a questionnaire to provide their general information, including sex, age, native place, physical status, life habit, family history, etc. The diagnosis of AGA was made by dermatologists. To determine the pattern of hair loss,Norwood-Hamilton classification system and Ludwig classification system were used for male AGA and female AGA, respectively. All the data were statistically analyzed by EpiData and SPSS11.5 software. Results Totally, 7056 subjects completed the questionnaire, including 3519 males and 3537 females, and the response rate was 72.5%. AGA was diagnosed in 809 patients, consisting of 701 males aging from 19 to 91 years (mean 64.16±11.9 years) and 108 females aging from 35 to 91 years (mean 70.46±18.89 years). The standardized prevalence (SP) was 9.47% in total, 15.73% in males and 2.73% in females; the difference was significant between males and females (χ2=356.00, P<0.001). A family history of AGA was observed in 52.7% of all subjects including 391 (55.78%) males and 35 (32.41%) females. Type Ⅲ vertex involvement was the most common type in men aging from 20 to 70 years old, and type Ⅵ in those over 70 years old. Grade Ⅰ and Ⅱ predominated in female AGA. Conclusions The results of this survey indicate that the prevalence of AGA is remarkably higher in men than that in women. Furthermore, the prevalence is steadily increased with advancing age in Shanghai.

BACKGROUND/OBJECTIVES:
Activating brown adipose tissue (BAT) and browning of white adipose tissue (WAT) can protect against obesity and obesity-related metabolic conditions.Cryptotanshinone (CT) regulates lipid metabolism and significantly ameliorates insulin resistance. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a receptor for cellular energy metabolism, is believed to regulate brown fat activity in humans.MATERIALS/METHODS: The in vivo study included high-fat-fed obese mice administered orally 200/400 mg/kg/d CT. They were evaluated through weight measurement, the intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), cold stimulation test, serum lipid (total cholesterol, triglycerides, and low-density lipoprotein) measurement, hematoxylin and eosin staining, and immunohistochemistry.Furthermore, the in vitro study investigated primary adipose mesenchymal stem cells (MSCs) with incubation of CT and AMPK agonists (acadesine)/inhibitor (Compound C).Cells were evaluated using Oil Red O staining, Alizarin red staining, flow cytometry, and immunofluorescence staining to identify and observe the osteogenic versus adipogenic differentiation. Quantitative real-time polymerase chain reaction and the Western blot were used to observe related gene expression.
RESULTS:
In the diet-induced obesity mouse model mice CT suppressed body weight, food intake, glucose levels in the IPGTT and IPTT, serum lipids, the volume of adipose tissue, and increased thermogenesis, uncoupling protein 1, and the AMPK pathway expression. In the in vitro study, CT prevented the formation of lipid droplets from MSCs while activating brown genes and the AMPK pathway. AMPK activator enhanced CT’s effects, while the AMPK inhibitor reversed the effects of CT.
CONCLUSION
CT promotes adipose tissue browning to increase body thermogenesis and reduce obesity by activating the AMPK pathway. This study provides an experimental foundation for the use of CT in obesity treatment.

Objective To explore the relationship of quality of life with optimisms and sense of coherence in adult kidney transplant recipients. Method A total of 295 kidney transplant recipients participated in the study by a self-designed general questionnaire, revised life orientation test (LOT-R), sense of coherence (SOC-13) and the MOS 36-item short form health survey (MOS SF-36). Results The mean score of mental health scale (PCS) was 47.02±7.30, which differed with different age, employment status and transplant vintage (P <0.01). The mean score of phyical health scale (MCS) was 46.87 ±11.14, which differed with education, economic burden and transplant vintage (P <0.05). PCS and MCS were positively correlated with the total score of sense of coherence (52.05%) and optimism (23.45%) (P<0.001). Optimism played a partially mediating role in the relationship between sense of coherence and quality of life. Conclusions The quality of life of kidney transplant recipients needs to be improved, which was at a low level.Optimism (medium to high level) and sense of coherence (medium to low level) are influencing factors of the quality of life. Improving accessment of mental state of patients with kidney transplant receients, paying more atentent and support to their mental change can improve their optimism and sense of coheherce and then life quiality.

Objective:To analyze the etiological distribution and phylogenetic characteristics of hand, foot and mouth disease (HFMD) in Qujing city of Yunnan Province in 2020.Methods:Stool samples were collected from HFMD cases in Qujing city in 2020 and virus RNA was extracted directly from treated stool suspensions. Virus VP4 gene sequences were firstly amplified using MD91/OL68-1 primer pairs and sequenced, then the virus serotypes were determined by BLAST search on the GenBank. Virus entire VP1 gene sequences were amplified and sequenced. Virus serotypes were identified online using Enterovirus Genotyping Tool Version 0.1. Sequences of reference virus genotypes/sub-genotypes were downloaded according to references. Phylogenetic trees were constructed by MEGA5.2 software and the genetic characteristics were analyzed.Results:A total of 47 strains of enteroviruses (EVs) were detected with a detection rate of 10.22% (47/460). The detected viruses were coxsackievirus A4 (CVA4, 0.65%, 3/460), CVA6 (7.83%, 36/460), CVA10 (0.87%, 4/460) and CVA16 (0.87%, 4/460). All were enterovirus species A (EVA), while other group viruses were not detected. The predominant virus was CVA6, accounting for 7.83% (36/460). EVA71 was not detected. CVA4 strains of C2 and C4 subgenotypes were co-circulating strains in Qujing city. CVA6 subgenotype D3a and CVA16 subgenotype B1a were also circulated in Qujing city. All CVA10 strains were in a separate lineage.Conclusions:Similar to the previous situation in China, the detection rates of EVA71 and CVA16 were very low, even zero. This study showed that CVA6 was the predominant virus, indicating a HFMD outbreak caused by CVA6 in Qujing city in 2020. The phylogenetic analysis showed CVA10 isolates belonged to a separate lineage, which might be unique to Qujing city. Laboratory and molecular epidemiological surveillance of non-EVA71 and non-CVA16 viruses, especially CVA6 and CVA10 should be strengthened in the future.
9.Analysis of the Impact of Upright Sitting Delivery on Fetal Head Descent and Maternal and Infant Outcomes in the Second Stage of Labor
Journal of Practical Obstetrics and Gynecology 2024;40(6):474-478
Objective:Using intrapartum ultrasound monitoring to observe and analyse the impact of upright sit-ting delivery on fetal head descent and maternal and infant outcomes during the second stage of labor.Methods:This study used a prospective randomized controlled study,including 110 pregnant women with full-term and com-plete opening of the cervix who were able to undergo vaginal delivery at Beijing Obstetrics and Gynecology Hospi-tal,Capital Medical University from February to September 2023.They were randomly divided into a control group(n=56)and an upright group(n=54)by simple randomization.The control group was delivered in routine supine or semi-supine positions,and the upright group was delivered in upright positions.The parturients in both groups were examined by color Doppler ultrasound at the beginning of the second stage of labor when the cervix was full-y opened to guide delivery and 30 minutes after guidance of the second stage of labor.Abdominal and perineal two-dimensional ultrasound was used to detect fetal head angle of progression(AOP),fetal head perineal dis-tance(HPD),and fetal orientation.At the same time,the time of the second stage of labor and delivery outcome were recorded.The changes in AOP,angle and position of HPD,delivery duration,and maternal and fetal out-comes between the two groups were analyzed.Results:At the beginning of the second stage of labor,there was no significant difference in AOP,HPD,and the rate of non-occipital anterior position of fetal position between the two groups(P>0.05).After 30 minutes of guiding delivery,compared with the control group,the AOP angle in-creased,the HPD distance shortened,and the proportion of non-occipital anterior fetal position was reduced in the upright position group,and all the differences were statistically significant(P<0.05).At the same time,compared with the control group,the spontaneous delivery rate,the duration of the second stage of labor,forceps delivery rate,lateral perineal incision rate,perineal edema rate,and oxytocin use rate were significantly decreased in the upright position group,and all the differences were statistically significant(P<0.05).All newborns were born a-live,and the 1-minute Apgar score was 10 for all newborns in both groups.There was no significant difference in birth weight between the two groups(P>0.05).Conclusions:When the parturient delivers in an upright sitting position in the second stage of labor,the AOP increases,the HPD shortens,and the time of the second stage of labor is accelerated to increase the natural delivery rate,reduce medical intervention,and reduce maternal and in-fant complications during delivery.
