Objective To investigate and analyze the examination and acceptance results for coalburning-borne endemic fluorosis control and elimination in Hubei Province.Methods A county-level selfinspection and a provincial-level spot-check were conducted to investigate the status of improved-stove usage,the situation of correctly drying corn and chili,and the dental fluorosis prevalence among children aged 8 to 12 in 501 historic coal-burning-borne endemic fluorosis villages of 6 counties (cities) in Hubei Province from 2012 to 2014.The endemic areas were selected according to the Control Standards of Endemic Fluorosis in Endemic Areas (GB 17017-2010) and Eliminating Standards of Coal-burning Type Endemic Fluorosis.Results The results of county-level inspection showed that the qualified rates of improved stoves,the correct-usage rates of qualified stoves,and the correctly drying rates of corn and chili were all higher than 98％ in targeted villages,and the prevalence rate of dental fluorosis of children was 7.73％ (2 319/30 003).The results of provincial-level recheck were more than 99％ and 8.25％ (353/4 277),respectively.The results of county-level inspection were of good consistency with those of provincial-level recheck (88.89％,48/54).Five counties (cities) but one had met the standard of fluorosis control or elimination.Conclusion Coal-burning-borne endemic fluorosis scope in Hubei Province is narrowed greatly and the prevalence rates are decreased significantly.

Objective To explore the efficacy and safety of irinotecan as neoadjuvant chemotherapy (INAC) plus radical surgery (RS) for cervical cancer.Methods According to International Federation of Gynecology and Obstetrics (FIGO),81 cases were divided into Ⅱ B,ⅡA,and Ⅰ B2 groups.According to the tests of UGT1A1 gene polymorphisms,we adjusted the injection dose of irinotecan.The parameters were analyzed,including the efficacy,operation time and bleeding volume,postoperative pathology,survival time,and adverse reactions.The articles on irinotecan or paclitaxel combined with cisplatin for neoadjuvant chemotherapy between 2005 and 2015 were collected,and compared.Results The effective rate of chemotherapy was 81.5％ (Ⅰ B2 group:85.7％;Ⅱ A group:83.3％;and ⅡB group:72.2％),operation time was (5.3 ± 1.1) h,and blood loss was (781 ± 361.7) ml.After chemotherapy,37 cases were delayed diarrhea,70 cases were nausea,48 cases were vomiting,and 40 cases were bone marrow suppression.The infiltration rate,operation time,and blood loss on Ⅱ B group was significantly higher than that on Ⅱ A and Ⅰ B2 groups(P ＜ 0.05),and there was no significant difference in the chemotherapy efficiency,invasion depth,lymphatic metastasis,survival time and adverse reactions(P ＞0.05).Compared to three articles,the total effective rate in this study was higher than that in previous studies,also in Ⅱ A and Ⅱ B group.Conclusions Irinotecan chemotherapy regimens combined with cisplatin is effective and well tolerated.It is worthy of popularization and application.Detection of UGT1A1 gene polymorphism has guiding significance for chemotherapy regimen on irinotecan combined with cisplatin.

AIM: To study the effect of hypoxia and hypercapnia on nitric oxide (NO) in plasma and superoxide dismutase (SOD), catalase (CAT), soluble guanylate cyclase (sGC), cyclic guanosine monophospholate (cGMP) in lung tissue in rats, and to explore the effect of NO- and H_2O_2-sGC pathway on the development of the pulmonary hypertension. METHODS: The model of hypoxic and hypercapnic 1, 2, 4-week group (HH 1 week, HH 2 weeks, HH 4 weeks) and control group was set up. NO content in plasma, CAT and SOD in rat lung were determined by spectrophotometry. The sGC activity in lung tissue was detected by enzyme kinetic analysis. cGMP content in lung tissue was examined with ~ 125 I-radioimmunoassay. RESULTS: The mean pulmonary artery pressure (mPAP) showed significantly higher in HH 1 week, HH 2 weeks and HH 4 weeks groups compared with control group (all P

Objective Through the dynamical monitoring of the water improvement projects operation,we intend to understand the prevalent trends of endemic fluorosis of children aged 8 to 12 in Hubei,to evaluate the effect of control measures and to provide the basis for making preventive measures.Methods In Hubei,ten surveillance counties were selected,and three epidemic villages were selected as fixed monitoring villages in each county from 2010 to 2014.In those villages,the operation situation of water improvement projects and the fluoride content in drinking water were detected,and the dental fluorosis of children aged 8 to 12 was diagnosed.Results From 2010 to 2014,the normal operation rate of water improvement projects was 75.61％-100.00％,the average of water fluorine content did not change,the differences were not statistically significant (F =2.00,P ＞ 0.05).The numbers of water improvement projects with water fluorine content in excessive amount was increased in the past five years which was only one project in 2010-2012 and was increased to two projects in 2013 and 2014.In 2010-2014,the dental fluorosis prevalence rate of whole children was 9.45％ (525/5 557),the dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was 42.40％ (92/217),the dental fluorosis prevalence rate of qualified villages was 8.11％ (433/5 340).The children's dental fluorosis prevalence rate of exceeding-standard villages of water fluoride content was higher than that in qualified villages;the differences were statistically significant (x2 =282.60,P ＜ 0.05).Conclusions The operation rate of water-improving projects is mostly higher than 90％,and so is the qualification rate of fluoride content in drinking water.The operation condition and water quality of the water-improving projects in Hubei need to be improved.The prevalence of children dental fluorosis of affected villages has dropped significantly after low fluoride water is provided continuously.

Objective To explore the relationship between Stathmin-1 and human papilloma viruse (HPV) persistent infection after conization of uterine cervix, and to show the clinical significance to recurrent of cervical intraepithelial neoplasia (CIN). Methods One hundred and six patients who were treated with conization of uterine cervix for CIN 2-3 grades were enrolled. Thirty-six recurrent patients were enrolled in recurrence group, and the others were enrolled in control group. The expression of Stathmin-1 in primary CIN tissues in two groups was detected by immunohistochemistry. The HPV infection was detected by HPV-DNA test. The relationship of HPV persistent infection and recurrence was analyzed. Results The positive expression rate of HPV persistent infection and HPV persistent infection rate in recurrence group were 88.89%(32/36), 83.33%(30/36), in control group were 34.29%(24/70) and 22.86%(16/70), and there were significant difference (P <0.01). Forty-two patients had HPV persistent infection in 56 patients with stathmin-1 positive expression, and 4 patients had HPV persistent infection in 46 patients Stathmin-1 negative expression. There was positive correlation (r=0.97, P<0.01). The type of HPV persistent infection in two groups was no significant difference (P >0.05). Conclusions Stathmin-1 positive expression is related to HPV persistent infection. The two factors can affect the prognosis of high-grade CIN, and can provide new cues and theory basis for the prevention of recurrence.

Objective To make clear the arsenic distribution in drinking water sources in Hubei Province, make provincial distribution map of high-arsenic water and provide scientific basis for formulating refined measures to prevent and control arsenic poisoning of drinking water type in Hubei Province. Methods In 103 counties of Hubei Province, residents were sampled according to different water supplies (centralized water supply, small centralized water supply in rural areas and decentralized water supply). One water sample was collected from source water and tap water in centralized water supply system and at least 3 samples were collected from decentralized water supply system in a village. Water iodine content was tested using atomic fluorescence spectrometry and a distribution map of high-arsenic water at county level was drawn using ArcGIS 10.2. Results Totally 38 292 water samples were collected. The water-arsenic-concentration median was less than 1.00 μg/L. The high-arsenic water detection rate in urban centralized water supply was 3.7%(80/2 176);which were all 0.1%(4/4 304,30/31 812) in small centralized water supply in rural areas and decentralized water supply. The high-arsenic water sources from centralized water supplies were distributed centrally in the south, the central and the east of Hubei Province and those from dispersed water supplies were distributed dispersedly in the south, the central and the east of Hubei Province.Conclusions There are still some dispersed water supplies with very high arsenic concentration in Hubei Province, which should be included to change the water area as soon as possible. Moreover, high arsenic water samples are found from centralized water supplies, which means the water treatment process should be upgraded or water resources should be changed.

Objective: To analyze physical fitness of students aged 6-22 years old from seven ethnic groups in Yunnan Province, and to provide reference for physical fitness intervention measures. Methods: The nationality, gender, grade, body shape, vital capacity, exercise quality of students were derived from the 2019 Yunnan Student Physical Health Survey Database. Comprehensive physical fitness score was calculated according to the National Student Physical Fitness Standards(revised in 2014). t test, ANOVA, and χ 2 test were used to analyze physical fitness score and level among students with different ethnic groups, gender, and school stages. Results: The average comprehensive score of physical fitness among students from 7 ethnic groups in Yunnan Province was (70.02±9.69）, with the pass rate being 88.91%. The proportion of excellent was 0.93%, good was 17.90%, pass 70.09 %, and failed was 11.09%. Physical fitness score was highest in BMI (94.99 points), followed by 50 meter running (74.13 points), sitting forward bend (72.63 points), endurance running (70.43 points), standing long jump (67.77 points), sit ups ( 65.71 points) , 1 minute skipping rope (65.25 points), vital capacity (62.97 points), pull up (29.04 points). Physical fitness score and pass rate and evaluation level varied significantly by ethnicity and school stage( F =293.53，452.85， χ 2/ χ 2 trend =466.65， 412.57 ； 1 553.22 ，1 045.36， P <0.01). Conclusion The excellent rate of physical fitness among students in Yunnan Province is relatively low. Physical fitness promotion requires specific guidance and training based on ethnicity and school stage.

Objective: To explore the genotype-phenotype correlation among 3 pedigrees affected with congenital aniridia. Methods: Clinical data and genomic DNA were collected and genetic variations were screened by whole-exome sequencing, with an emphasis on PAX6-related genes.Suspected variations were verified by Sanger sequencing and quantitative polymerase chain reaction (PCR). Written informed consent was obtained from the parents of each propositus prior to entering study cohort.This study protocol was approved by Ethic Committee of Henan Eye Hospital (No.HNEECKY-2017(6)). Results: Genetic analysis identified that a nonsense c. 949 C>T variation and an c. 141+ 1 G>T splicing variation of the PAX6 gene in two of the probands, while the remainder has carried a duplication in 11 p13 (chr11: 31531331-31827959) encompassing the PAX6 and ELP4 genes.Phenotype analysis showed that the probands carrying the nonsense and splicing variations had classical features including complete aniridia, macular hypoplasia, microcornea and nystagmus; the proband carrying the 11p13 duplication had microphthalmos, microcornea, macular dysplasia, iris dysgenesis, and nystagmus. Conclusions The 11p13 duplication involving the PAX6 gene may have caused over-expression of PAX6 gene, resulting in severe eye abnormalities including microphthalmos and microcornea, macular dysplasia and nystagmus.The relatively mild iris dysgenesis has distinguishing it from classical aniridia due to PAX6 haploinsufficiency.
