Objective:Exploratory study on the relationship between TCM syndrome types, TCM constitution and clinical symptoms of idiopathic central precocious puberty children and rapidly progressive early development children in Shanghai, so as to provide a basis for early intervention and syndrome differentiation and treatment.Methods:A cross-sectional study and retrospectively enrolled. Through questionnaire survey, the basic information, clinical symptoms and TCM constitution of children diagnosed with idiopathic central precocious puberty and rapidly progressive early development were collected from the Pediatric Endocrinology Clinic of Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from July to August 2022, and the correlation between the distribution, differentiation and clinical symptoms of TCM constitution in children with idiopathic central precocious puberty and children with rapidly progressive precocious puberty in Shanghai were explored through data analysis.Results:① Fast progressive early development children with higher BMI and age than idiopathic central precocious puberty were statistically significant ( P<0.05), and no significant difference in the sex composition ratio between the two groups. ② Among children with idiopathic central precocious puberty and children with rapid progressive early development, the proportion of liver depression fire syndrome was the highest, 59.15% (42/71) and 46.51% (60/129) respectively, and the proportion of Qi depression was the highest, 35.21% (25/71) and 36.43% (47/129) respectively. However, there was no significant difference in the TCM syndrome types and physical distribution of the two groups. ③ The TCM syndrome types of 200 precocious children weres correlated with physical distribution, among which Yin deficiency fire flourishing syndrome was significantly associated with Yin deficiency, liver stagnation fire syndrome was significantly correlated with qi depression, and phlegm dampness obstruction syndrome was significantly correlated with phlegm dampness and Yang deficiency ( P<0.01). ④ A total of 200 children with precocious puberty were more female than male, male BMI was higher than female, and the BMI of children with precocious puberty was higher than other syndrome types, and the differences were statistically significant ( P<0.01). Liver stasis fire syndrome was the highest proportion between boys and girls, but there was no obvious difference in TCM syndrome types between different genders. The highest proportion of breast pain in clinical symptoms was 22.19% (69/311). Conclusion:Children with idiopathic central precocious puberty and rapidly progressive early development children have differences in age and BMI, with no obvious difference in gender composition, TCM syndrome type and physical distribution, but there is a correlation between TCM syndrome type and physical constitution of precocious puberty children.

Objective To assess the value of 18F-fluorodeoxyglucose (FDG) PET/CT in the staging,interim therapeutic and prognostic evaluation of mucosa-associated lymphoid tissue (MALT) lymphoma.Methods Thirty-six MALT lymphoma patients (20 males,16 females;average age:61.7 years) confirmed by pathology from January 2008 to January 2018 were retrospectively analyzed.18F-FDG PET/CT were performed before chemotherapy and radiotherapy for staging.The detective sensitivity was evaluated.The staging results of gastric MALT lymphoma and extragastric MALT lymphoma by PET/CT were compared with Fisher exact probability method.PET/CT was performed in 17 of 36 patients after 4 courses of chemotherapy,and 17 patients were divided into positive group (≥≥4) and negative group (＜4) according to scores of Deauville 5-point scale.The progression-free survival (PFS) was evaluated using Kaplan-Meier survival analysis.Results FDG-positive lesions were found in 31 of 36 patients with the sensitivity of 86.1％ (31/36).The results of PET/CT were negative in stage Ⅰ patients.In stage]Ⅱ-Ⅳ patients,the results of 18F-FDG PET/CT combined with bone marrow biopsy were in accordance with the results of clinical staging.The accuracy of PET/CT in staging of gastric MALT lymphoma patients was 9/17,which was significantly lower than that of extragastric MALT lymphoma patients (17/19;P=0.025).The PFS of negative group evaluated by interim PET/CT was longer than that of positive group (x2 =4.16,P＜0.05).The 2-year PFS rates of the 2 groups were (85.7± 13.2)％ and (27.8 ±21.3)％,respectively.The PFS of patients with low expression of Ki-67 was significantly longer than that of patients with high Ki-67 expression (x2=4.22,P＜0.05).Conclusions In stage]Ⅱ-Ⅳ MALT patients,18F-FDG PET/CT combined with bone marrow biopsy can improve the staging accuracy.The staging accuracy of PET/CT in extragastric MALT lymphoma is significantly higher than that of gastric MALT lymphoma.PET/CT and Ki-67 can provide effective information on the prognostic evaluation for patients with MALT lymphoma.

Objective To understand HIV incidence in community residents and epidemiological characteristics of newly detected HIV infection cases in Dali,Yunnan province.Methods A cohort study was conducted among 146720 community residents who were tested to be HIV negative during 2010-2011,they were followed-up from June 1,2014 to May 31,2015.Results A total of 136356 community residents received follow up (92.9％).The follow-up time was 0.23-5.40 years (medium:3.43 years),cumulatively 459675 person years,and 78 people were found to be HIV positive.The incidence rate of HIV infection was 0.170/1000 person years.The incidence rate was 0.037/1000 person years in age group 15-29 years,0.288/1000 person years in age group 30-44 years,0.210/1000 person years in age group 45-59 years,0.204/1000 person years in age ≥60 years;0.213/1 000 person years in males,0.130/1000 person years in females;0.248/1000 person years inHan ethnic group,0.149/1000 person years in Minorities;0.194/1000 in people with education level ≤junior middle school,0.046/1000 person years in people with education level ＞ junior middle school;0.070/1000 person years in the unmarried,0.194/1000 person years in the married and 0.425/1000person years in the divorced/widowed.Cox proportional hazards regression analysis showed that being male (HR=l.731),aged 30-44 years (HR=13.158),aged 45-59 years (HR=10.329),aged ≥60years (HR=8.291),unmarried (HR=3.162) and divorced/widowed (HR=2.689) were the risk factors for HIV infection,while the education level ＞ junior middle school (HR=0.132) was the protective factor for HIV infection.Conclusions By medium 3.43 years follow up,the cohort study showed that incidence rate HIV infection was 0.170/1000 person years in the community residents in Dali.Male,middle aged and old people,people with low education level,the unmarried and the divorced/widowed had relatively higher risk to be infected with HIV,Close attention should be paid to the prevention and control of AIDS in these populations.
