Objective To evaluate the effectiveness of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, so as to provide insights into echinococcosis control. Methods Administrative villages were sampled using a multi-stage cluster random sampling method from Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, and all residents at ages of 12 years and older in the sampled villages were screened for echinococcosis, and schools were sampled using a cluster sampling method, and all children at ages of 12 years and older in the sampled schools were screened for echinococcosis. Domestic dogs were sampled using a systematic random sampling method, and one domestic dog stool sample was collected from each household. Stray dog stool samples were collected outside the villages, and Echinococcus coproantigens were detected using enzyme-linked immunosorbent assay in domestic and stray dogs. In addition, echinococcosis was screened in sheep and cattle in designated slaughterhouses in Tianzhu Tibetan Autonomous County. The trends in the prevalence of echinococcosis in humans and livestock and the positive rate of Echinococcus coproantigens in dogs were examined with the Cochran-Armitage trend test. In addition, individuals screened for echinococcosis were randomly sampled from 2007 to 2022 for survey on the awareness of echinococcosis control knowledge. Results A total of 290 356 person-times were screened for echinococcosis among residents at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 094 residents detected with cystic echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ² = 358.602, P < 0.001). A total of 32 931 person-times were screened for echinococcosis among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 296 children detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a gradual decline over years (χ² = 267.673, P < 0.001). A total of 33 230 domestic dog stool samples were tested for Echinococcus coproantigens in Tianzhu Tibetan Autonomous County, Gansu Province from 2007 to 2022, with 1 777 Echinococcus coproantigens-positive samples tested, and the positive rate of Echinococcus coproantigens appeared a tendency towards a decline in domestic dogs over years (χ² = 2 210.428, P < 0.001), while the positive rate of Echinococcus coproantigens showed a tendency towards a rise in domestic animals from 2016 to 2022 (χ² = 37.745, P < 0.001). The positive rate of Echinococcus coproantigens remained relatively stable in stray dogs in Tianzhu Tibetan Autonomous County, Gansu Province from 2019 to 2022 (χ² = 0.315, P = 0.575). A total of 10 973 sheep were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2007 to 2022, with 334 sheep detected with echinococcosis, and the detection of echinococcosis appeared a tendency towards a decline in sheep over years (χ² = 53.579, P < 0.001); however, there was no significant change in the detection of echinococcosis during the period from 2015 through 2022 (χ² = 1.520, P = 0.218). A total of 2 400 cattle were screened for echinococcosis in Tianzhu Tibetan Autonomous County from 2017 to 2022, with 231 cattle detected with echinococcosis, and the detection of echinococcosis showed a tendency towards a decline over years (χ² = 5.579, P < 0.05). The awareness of echinococcosis control knowledge increased from 44.37% in 2007 to 94.00% in 2022 among residents at ages of 12 years and older and from 52.50% in 2007 to 92.50% in 2022 among children at ages of 12 years and older in Tianzhu Tibetan Autonomous County, respectively. Conclusions There has been a reduction in the detection of echinococcosis in humans and domestic animals and the positive rate of Echinococcus coproantigens in dogs and a rise in the awareness of the echinococcosis control knowledge following the implementation of the central government-funded echinococcosis control programme in Tianzhu Tibetan Autonomous County, Gansu Province; however, integrated echinococcosis control measures are still required for further control of the prevalence of echinococcosis.

Objective: To investigate the current status of myopia in children and adolescents in Qamdo, Tibet, and analyze related influencing factors, so as to provide a basis for the prevention and control of adolescents in plateau areas. Methods: A cross sectional study was conducted among 959 children and adolescents randomly selected from one district and two counties in Qamdo (from the fourth grade of elementary school to the second grade of high school) for visual acuity and refraction tests and filled out a vision related behavior questionnaire to analyze the incidence of myopia among adolescents in the region and its associated factors. Results: The myopia rate of adolescents in grades 4-11 was 54.43%, the rate of undercorrection of refractive errors was 85.25%, and the percentage of students wearing eyeglasses was 34.67%,fully vision correction rate was 42.54%. The myopia rate of students in grades 4-6 was 35.14%, 64.71% in grades 7-9, and 73.48% in grades 10-11. The myopia rate increased with grades( χ 2= 101.18 , P <0.01). The myopia rate (70.40%) of urban students (grades 4-9) was higher than that of county level(41.45%), and the myopia rate of students with myopia from either parent (68.24%) was higher than that of students without myopia (51.91%) , the myopia rate of girls (59.96%) was higher than that of boys (48.36%)( χ 2=53.19，13.46，12.98， P <0.01). Use electronic products for more than 2.5 hours per day, electronic devices usage after bedtime, the light low indoor brightness when studying on a sunny day, and only use one of the table lamps or roof lights when studying at night, preference for fried food, poor sleep quality, in the morning the students who still feel tired are at higher risk of myopia( χ 2=10.35, 10.91, 6.87, 4.25, 4.97, 5.71, 12.11, P < 0.05). Multivariate regression analysis showed that the occurrence of myopia was related to region, grade, gender, parental myopia, time spent on electronic products every day in the past 5 months, and sleep quality( P <0.05). Conclusion The high rate of myopia in children and adolescents in Qamdo may be related to the quality of sleep, the length of time electronic products are used, the eye environment, and the frequency of eating fried foods. Outdoor activities do not show significant differences.

Objective:To evaluate and compare efficacy of intravenous immunoglobulin (IVIG) versus recombinant human tumor necrosis factor-α receptor Ⅱ:IgG Fc fusion protein (rhTNFR:Fc) in the treatment of toxic epidermal necrolysis (TEN) .Methods:Clinical data were collected from patients with TEN treated with IVIG or rhTNFR:Fc in Wuhan No.1 Hospital from 2013 to 2019. There were 11 patients in the IVIG group, including 3 males and 8 females, aged 25-72 years, and the median TEN-specific severity-of-illness score (SCORTEN) was 3 points; there were 10 patients in the rhTNFR:Fc group, including 5 males and 5 females, aged 32-84 years, and the median SCORTEN was 2 points. These patients all showed no response to the 5-day treatment with prednisolone acetate at a dose of 0.6-1.0 mg·kg -1·d -1, and then received IVIG at a dose of 400 mg·kg -1·d -1 for 5 consecutive days, or subcutaneous injection of rhTNFR:Fc at a dose of 25 mg every other day for 4-6 sessions. Changes in skin lesions and adverse events were recorded in the 2 groups. Statistical analysis was carried out by using Mann-Whitney U test. Results:Compared with the rhTNFR:Fc group, the IVIG group showed a significant decrease in the time to onset of reduction of skin lesion exudate (1.73 ± 1.19 days vs. 3.00 ± 1.56 days, P < 0.05) , time to onset of pain relief in the lesion area (1.64 ± 1.28 days vs. 3.70 ± 1.63 days, P < 0.05) , time to lightening of color of the lesion base (2.45 ± 1.12 days vs. 3.90 ± 1.59 days, P < 0.05) , time to onset of new epidermis growth (3.09 ± 1.13 days vs. 5.20 ± 1.22 days, P < 0.05) , and in the time to onset of lesion drying at the intertriginous sites (4.82 ± 2.22 days vs. 7.90 ± 3.14 days, P < 0.05) . However, there was no significant difference in the length of hospital stay between the IVIG group (17.70 ± 8.33 days) and rhTNFR:Fc group (16.70 ± 4.71 days, P > 0.05) . No adverse reactions were observed during the treatment, and no recurrence or complications were found in the 21 patients during the follow-up of 6 months. Conclusion:IVIG and rhTNFR:Fc are both effective in the treatment of TEN, but IVIG is superior to rhTNFR:Fc in terms of the time to onset of pain relief, skin lesion exudate reduction and epidermal growth.

Objective To study the prevalence of hyperuricemia and its risk factors in elderly people of Yiyang District,Hunan Province,China.Methods A total of 1363 elderly people undergoing physical examination in our hospital were divided into hyperuricemia group (n=245) and control group (n=1118).Their general clinical data were recorded and compared.The risk factors for hyperuricemia were analyzed.Results The age was significantly older,number of males was significantly larger,the serum TG,LDL-C,urea,UA levels and body height,BMI,SBP were significantly higher while the serum TC and HDL-C levels and Cr clearance rate were significantly lower in hyperuricemia group than in control group (P＜0.05,P＜0.01).Pearson correlation analysis showed that serum UA level was positively related with age,serum TG and urea level,BMI,SBP and DBP,but negatively related with Cr clearance rate and serum TC,LDL-C,HDL-C levels (P＜ 0.01).Binary logistic regression analysis showed that age,male gender,hyperlipidemia,and obesity were the independent risk factors for hyperuricemia after adjustment of age (OR=1.857,95 ％ CI:1.302-2.649,P=0.001;OR=1.866,95％CI:1.363-2.555,P=0.000;OR=2.214,95％ CI:1.716-2.856,P=0.000).However,serum HDL-C level and Cr clearance rate were the protective factors for hyperuricemia (OR =0.388,95 ％ CI:0.242-0.623,P =0.000;OR =0.948,95％CI:0.937-0.959,P=0.000).Conclusion The prevalence of hyperuricemia is rather high in elderly people of Yiyang Distric,Hunan Province,China,suggesting that the lifestyle of elderly people should be improved and hyperuricemia should be treated with appropriate drugs.

Objective To investigate the expression of human leucocyte antigen G (HLA-G) in urothelial carcinoma after renal transplantation,and to analyse the relationship between HLA-G expression and the various clinical and pathological parameters.Methods 29 patients with urothelium carcinoma after renal transplantation for the first time from January 2005 to June 2016 were selected as the experimental group,the age range was 32-70 years,with an average of (55.5 ± 8.1) years.29 non-transplanted patients with urothelial carcinoma as the control group 1,the age range was 36-74 years,with an average of (57.9 ± 8.2) years.15 cases of normal urinary tract epithelial were from cystoscopy biopsy as the control group 2.Immunohistochemical method was used to detect the difference of HLA-G expression between the three groups.The clinical and pathological data of patients with urothelial carcinoma after renal transplantation were analyzed.Results The expression rate of HLA-G was 79.3％ (23/32) in patients with urothelial carcinoma after renal transplantation,37.9％ (11/32) in non-transplanted group and 0 (0/15) in normal urinary tract epithelium group.The expression rate of HLA-G in non-transplanted group was significantly higher than that in normal urinary tract epithelium group (P ＜ 0.05).The expression rate of HLA-G in patients with urothelial carcinoma after renal transplantation was significantly higher than that in nontransplanted group and normal urinary tract epithelium group (P ＜ 0.05).Conclusions HLA-G is associated with the occurrence of urothelial carcinoma after renal transplantation.It may provide a new idea for the prevention and treatment of urinary tract epithelium after renal transplantation.

OBJECTIVETo observe the effectiveness and safety of electrothermal acupuncture in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in the cancerous patients of phlegm-stasis interaction in cisplatin-containing chemotherapy.

METHODSSixty cases of phlegm-stasis interaction in cisplatin-containing chemotherapy were randomized into a trial group and a control group, 30 cases in each one. In the control group, the intravenous drip of granisetron hydrochloride injection was adopted, 3 mg before and after cisplatin-containing chemotherapy 30 min, continuously for 3 days. 43 to 45℃ electrothermal acupuncture at zusanli(ST 36) for 30 min was used on the basis of the treatment as the control group in the trial group,once a day for 3 days. CINV, anti-nausea effects, Karnofsky score, the syndrome score of phlegm-stasis interaction, and relevant indices of safety were observed on the 1st and 7th days of cisplatin-containing chemotherapy separately.

RESULTS1.Regarding CINV and anti-nausea effect, CINV did not occur before chemotherapy in the patients of the two groups. On the 1st and 7th days of chemotherapy, CINV in the trial group were milder than those in the control group (both<0.05).The anti-nausea effects in the trail group were better than those of the control group.2.Regarding Karnofsky score and the syndrome score of phlegm-stasis interaction, the improvements on the 7th days of chemotherapy in the trial group were better than those in the control group, indicating the significant differences (both<0.05). 3.Regarding the safety indies, there was no adverse reaction during the treatment in the two groups.

CONCLUSIONSThe electrothermal acupuncture effectively relieves CINV, and improves self-care dbility and the symptoms of phlegm-stasis interaction.

Objective To discriminate whether chemical compounds are micronuclei-inducing by counting the ratio of bone marrow micronucleus polychromatic erythrocytes ( MNPCE) dyed with a single fluorescence reagent ( acriding organe, AO) by single-laser flow cytometry.Methods Treating male KM mice and SD rat with cyclophosphamide ( CP) respectively, and counting their frequencies of micronucleated polychromatic erythrocytes ( MNPCE) as well as frequencies of micronucleated normochromatic erythrocytes ( MNNCE ) in bone marrow by AO and a single_laser flow cytometer (FCM), comparing and analyzing the results from different methods.Results The results showed that, along with increasing dose of CP, the ratio of MNPCE also corresponding increase, suggesting significant quantative-efficiency correlation.MNPCE were also counted manually by fluorescence microscopy, and the results showed no significant difference with that by flow cytometry.Conclusions AO_FCM fully automated detection method for the detection of MNPCE and MNNCE in mice and rat bone marrow micronucleus rate is reliable.

ObjectiveTo explore the histopathological changes of bile duct,liver and local tissue for injurious biliary stricture(IBS). MethodTo observe the morphological and pathological changes of bile duct, local tissue and liver in different periods with dogs as the established animal model for IBS. ResultBile duct obstruction due to injury can expand the proximal bile duct up to 18.91 ±1.85 mm as the pressure goes up. Damage to local tissue triggers acute inflammation. In early injury phase (within 10 d), inflammatory cell infiltration and proliferation appears on the wall of the duct with increased mucosal edema as well as thickening of the biliary ductile wall. In the late injury phase (15 d), the degree of infiltration of inflammatory cells, edema and mucosal thickness were reduced whereas fibroblast and collagen tissue were proliferated extensively. The wall of biliary duct also becomes fibrotic and thickens. Quantitative analysis of the inflammatory edema shows the most severe outcome on the 5th day (HE staining WBC count of 54.2±5.8 unit) and its severity progressively subsides on the 15th day. (HE staining WBC count of 41.7±7.2 vs 54.2±5.8 a, P＜0.0,5). In the early obstruction (5 d and 10 d), the liver cells showed mild to moderate swelling and its degeneration is often associated with steatosis and sinusoidal expansion and congestion. As the obstruction time increases in the 20 d and 30 d group, liver cells starts to show extensive vacuolation and sinusoidal occlusion. ConclusionsEarly phase (5 days) of acute bile duct obstruction due to injury shows rapid expansion of the bile duct, edema in the bile duct itself as well as its surrounding tissue and liver damage. After 15 days, the local inflammatory edema is greatly reduced and is replaced by hyperplasia of fibers and collagen. Liver damage appears to be irreversible after 20 days. Considering local environmental and systemic conditions, the optimal time frame to repair obstruction of bile duct surgically is between 10-20 days.
