OBJECTIVETo find out an appraisal method of temperature on the first appearance date of Culex tritaeniorhynchus in spring.

METHODSWhole night collection of mosquitoes mosquitoes (from 18:00 hours to 06:00 hours of the following day) with light traps had been carried out in pig sties every night since 1 March in 1982 - 1992 and 2001 - 2002 in Fengxian area Shanghai. The adult mosquitoes caught were anaesthetized, then identified and counted. The density of mosquitoes was calculated by the average number of mosquitos per one trap and one night. Comparative analysis of the mean daily air temperature at 7 days before, the first appearance date and 1 day after, the first appearance date of Culex tritaeniorhynchus.

RESULTSData of the first appearance data of Culex tritaeniorhynchus were judged to mean daily air temperature and cumulative temperature on the day of the first appearance of Culex tritaeniorhynchus and the day before appearance, or 3 days on the day of the first appearance of Culex tritaeniorhynchus and the two days before appearance and the day since appearance with a difference less than 1 - 2 day (91.7%).

CONCLUSIONThe first appearance of Culex tritaeniorhynchus in spring accompanied with a course of influence by the severe warm air advection from south of China, and lowest mean daily air temperature of the first appearance was 11 degrees. Thus the first appearance data of Culex tritaeniorhynchus could be deduced and rehabilitated from observed values of mean daily air temperature or its forecasting values.

The great omentum is an intraperitoneal organ and plays an important role in protecting the environment of the peritoneal cavity. Several specialized innate immune cells including B1 cells and resident macrophages are found in the omentum, which may be attributed to the unique niche and its special stromal cells. However, it is not clear how these omental innate immune cells contribute to the peritoneal immunity. This review attempts to summarize the latest research on the omental innate immunity and discuss its involvement in the immune response of the peritoneal cavity.

's acupuncture school in Gansu,represented byand,is of great influence in China.'s acupuncture school originated from(Inner Canon of Yellow Emperor) and(Classic of Questioning),and shaped aroundDynasty andDynasty. Professorhas formed a unique "'s acupuncture" diagnosis and treatment system by inheritance and innovation. He clinically paid attention to basic training,obtainingand keeping spirit,as well as syndrome differentiation,reinforcing and reducing. Also,he took the priority the pressing hand with bilaterally needle manipulation. Besides,he thought important simplicity,innovation and acupoints selecting according to time. We inherited's acupuncture from his family,teachers'techniques,international communication,college and university education and scientific research. In this article we prescribe the development,the inheritance and the protection measures of's acupuncture school in terms of its origination,academic thought,and inheritance research,etc.,so as to provide references for further study and inheritance.

OBJECTIVE: To analyze the clinical characteristics and prognosis of 40 children with myelodysplastic syndrome (MDS), and provide ideas for clinical diagnosis and treatment. METHODS: The clinical characteristics, risk stratification, and different treatment regimens of 40 cases with MDS admitted in Department of Hematology of Children's Hospital of Soochow University from January 1, 2011 to December 31, 2017 was retrospectively analyzed. Kaplan-Meier survival curve were used to estimate 3-year overall survival (OS) rate and event-free survival (EFS) rate. RESULTS: In 40 cases, the ratio of male to female was 1.4∶1.0, male was more than female, and median age was 6.0 years old. Among them, refractory cytopenia (MDS-RCC) was the most common type, and 11 cases were chromosomal abnormalities, 21 cases genetic abnormalities. Fifteen cases accepted hematopoietic stem cell transplantation (HSCT) treatment, while 25 cases did not but drug therapy alone. The 3-year OS rate of the cases who accepted HSCT or not was (72.2±12.2)% and (35.3±10.2)% (P=0.039), 3-year EFS rate was (65.0±12.9)% and (19.2±8.4)% (P=0.012), respectively. Cox regression analysis showed that age < 7 years old (P=0.0333), initial diagnosed platelet < 50×10⁹/L (P=0.007), presence of complex karyotypes and/or gene mutations (P=0.0002), and treatment without HSCT (P=0.016) were the high-risk factors of prognosis. All the children were classified according to IPSS, WPSS and IPSS-R, while analysis result showed that the above three risk assessment had limitations for risk assessment of MDS in children, they could not comprehensively assess the prognosis of children with MDS. CONCLUSION MDS-RCC in children is more common. Cox multivariate analysis shows that age < 7 years old, initial diagnosed platelet < 50×10⁹/L, presence of complex karyotypes and/or gene mutation, and treatment without HSCT are the high-risk factors of prognosis in children with MDS. HSCT is the most effective treatment to cure children with MDS at present. The current methods such as IPSS-R commonly used in assessment of prognosis in children with MDS show obvious limitation.

OBJECTIVETo explore clinical significance of monitoring the level of minimal residual disease (MRD) at different time point in the risk stratification and prognosis of Childhood B-lineage Acute Lymphoblastic Leukemia.

METHODSThree hundred and eighty cases of children's B-ALL from Augest 2008 to January 2013 in our hospital were enrolled in this study. MRD levels were detected at day 15, day 33 and week 12 after initial chemotherapy. The event-free survival(EFS) and overall survival (OS) were measured on the basis of MRD levels at different stages of chemotherapy and were compared by Kaplan Meier analyses.

RESULTSThe patient's age, initial white blood cell count, chromosome, MLL, BCR/ABL, pretreatment reaction, bone marrow MRD at days 33 were closely related with the 5-year EFS rate. Multiparameter flow cytometry showed the marked MRD and unmarked MRD were not significantly different between their 5-year EFS rate(P>0.05), and the every immune phenotype was also no significantly different between the 5-year EFS rate(P>0.05). The children with MRD≥10at day 15(P<0.01), MRD≥10at day 33 (P<0.01) and MRD≥10on week 12(P<0.01) have a decreased 5-year EFS rate and overall survival, which related with poor prognosis obviously. The 5-year EFS rates at the MRD<10(negative), 10-10, 10-10and ≥10at day 33 were 86.6±2.7%, 77.5±4.9%, 70.1±8.0%, and 44.8±9.9%(P<0.01) with significant difference respectively; the 5-year OS rate was 89.5±2.7%, 80±4.9%, 76.0±7.8%, and 53.2±10.1% with statistically significant difference(P<0. 01).

CONCLUSIONThe MRD≥10at day 33 is a high risk factor for significant reduction of the 5-year EFS rate and the 5-year OS rate of children with B-ALL. Thus, dynamic monitoring the MRD level can predict relapse of B-ALL after remission.

OBJECTIVES: To examine the reliability and accuracy of Walker's model for estimating the sex of Han adults in western China by using cranium three-dimensional (3D) CT reconstruction, and to study the suitable cranial sex estimation model for Han people in western China. METHODS: A total of 576 cranial CT 3D reconstructed images from Hanzhong Hospital in Shaanxi Province from 2017 to 2021 were collected. These images were divided into the experimental group with 486 samples and the validation group with 90 samples. Walker's model was used by observer 1 to estimate the sex of experimental group samples. The logistic function applicable to Han people in western China was corrected by observer 1. The 90 samples in the validation group were scored and substituted into the modified logistic function to complete the back substitution test by observer 1, 2 and 3. RESULTS: The accuracy of sex estimation of Han adults in western China was 63.2%-77.2% by applying Walker's model. The accuracy of modified logistic function was 82.9%. The accuracy of sex estimation through back substitution test by 3 observers was 75.6%-91.1%, with a Kappa value of 0.689 (P<0.05) for inter-observer consistency and 0.874 (P<0.05) for intra-observer consistency. CONCLUSIONS There are great differences in bone characteristics among people from different regions. The modified logistic function can achieve higher accuracy in Han adults in western China.
