Objective:To learn about the iodine nutrition level and its spatial distribution status in key populations in Hubei Province, so as to provide a basis for adjustment of iodine supplementation policy and the realization of scientific and accurate iodine supplementation.Methods:In 2020, a sampling was carried out in Hubei Province according to the "National Iodine Deficiency Disorders Monitoring Plan (2016 Edition)" to monitor the concentration of salt iodine and urinary iodine of key populations (children ages 8 - 10 years old and pregnant women). The spatial distribution of iodine nutrition levels was analyzed by spatial epidemiology.Results:The median salt iodine of 17 263 children's family salt samples was 25.0 mg/kg, and the median urinary iodine (MUI) was 217.0 μg/L. There was significant spatial aggregation in the distribution of urinary iodine level in children at the county level ( Moran's Index = 0.36, P < 0.001). The significant hot spot areas with high urinary iodine level among children were located in Shiyan City and Xiangyang City, while the significant cold spot areas with low urinary iodine level were mainly concentrated in Yichang City. The median salt iodine of 8 618 pregnant women's family salt samples was 25.1 mg/kg, the MUI was 176.3 μg/L. The urinary iodine level among pregnant women at the county level was spatially clustered ( Moran's Index = 0.22, P = 0.003) . The significant hot spot areas with high urinary iodine level among pregnant women were mainly in Enshi Tujia and Miao Autonomous Prefecture, the significant cold spot areas were mainly concentrated in Yichang City. Conclusions:In 2020, the iodine nutrition of children in Hubei Province is at a super appropriate level (200 - 299 μg/L), and the iodine nutrition status of pregnant women is more sensitive, which is close to the lower limit of the appropriate level (150 μg/L). The urinary iodine level of children and pregnant women has significant spatial aggregation at the county level. Targeted intervention will be needed in counties (dictricts) where the urinary iodine level is lower or higher than the normal range, to achieve accurate and scientific iodine supplementation.

Objective:To investigate the role of integrin-linked kinase (ILK)-small interfering RNA (siRNA)-adeno-associated virus (AAV) in scar formation after glaucoma filtering surgery in rat eyes.Methods:Forty-eight Sprague Dawley rats of SPF grade, aged 8 to 9 weeks old, were selected and divided into blank control group, ILK-siRNA-AAV group, NC-siRNA-AAV group and mitomycin C (MMC) group by random number table method, with 12 rats in each group.Left eyes of the rats were taken as experimental eyes, and no intervention was administered to fellow eyes.The bulbar conjunctival filtering bleb after glaucoma filtration surgery in rats was established by anterior chamber drainage tube implantation.One day after operation, phosphate buffer solution, ILK-siRNA-AAV, and NC-siRNA-AAV were injected into the filtering bleb of blank control group, ILK-siRNA-AAV group and NC-siRNA-AAV group, 5 μl each group, respectively.Cotton tablets containing 0.4 mg/ml MMC were placed under conjunctival flap for 5 minutes during operation in MMC group.Intraocular pressure (IOP) was measured with a handheld tonometer before surgery and at 1, 2, 3, 7, 14, 21, 28 days after surgery.Formation of filtering blebs in rats was observed with a surgical microscope at 1, 2, 3, 7, 14, 21, 28 days after operation, and the bleb survival time was calculated by Kaplan-Meier survival analysis.The mRNA and protein expression levels of ILK in conjunctival and subconjunctival tissues at the surgical sites were detected by reverse transcription PCR and Western blot, respectively, on the 28th day after operation.Silencing of ILK gene was identified.Effect of ILK gene silencing on the morphology of drainage pathway was observed by hematoxylin-eosin staining.Effect of ILK gene silencing on collagen fiber deposition in the bulbar conjunctiva at filtration area was examined by Masson staining, and the percentage of positive area of collagen fiber staining in the total tissue visual field was calculated.The use and care of the animals complied with the ARVO Statement.This research protocol was approved by an Ethics Committee of Xi'an Jiaotong University (No.2013-772). Results:There were statistically significant differences in IOP at different time points between before and after surgery among four groups ( Fgroup=76.84, P<0.001; Ftime=114.49, P<0.001). The IOP of ILK-siRNA-AAV group on the 1st, 7th, 14th and 28th day after operation and the IOP of MMC group on the 2nd, 3rd, 7th, 14th and 28th day after operation were lower than those of blank control group, and the differences were statistically significant (all at P<0.05). The IOP of ILK-siRNA-AAV group was lower on 7th, 14th, 21st and 28th day after operation than those of NC-siRNA-AAV group, with statistically significant differences (all at P<0.05). The bleb survival time of blank control group, NC-siRNA-AAV group, ILK-siRNA-AAV group and MMC group was (3.50±1.51), (5.00±3.41), (31.50±3.15) and (31.33±2.46) days, respectively, with a significant difference among them ( F=395.83, P<0.05). The bleb survival time of ILK-siRNA-AAV group and MMC group was higher than that of blank control group and NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). There were statistically significant differences in the relative expression levels of ILK mRNA and protein among four groups ( F=222.32, 752.69; both at P<0.05), and the relative expression levels of ILK mRNA and protein were significantly lower in ILK-siRNA-AAV group than blank control group and NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). Proliferative fibrous connective tissue and a large number of cells at surgical sites were found in blank control group and NC-siRNA-AAV group, and the fibroblasts were of a high density and grew in clumps.In ILK-siRNA-AAV group, the bulbar conjunctiva was thin, and the arrangement of fibrous connective tissue was loose, and a few proliferative fibroblasts were found.In MMC group, the conjunctival fibrous layer was loose and thin, forming cavities, and scarce cells were found.There was statistically significant difference in the percentage of collagen fiber positive staining area among four groups ( F=741.66, P<0.05). The positive staining percentage of ILK-siRNA-AAV group and MMC group was significantly lower than that of blank control group, among which there was lower positive staining percentage in ILK-siRNA-AAV group than NC-siRNA-AAV group, and the differences were statistically significant (all at P<0.05). Conclusions:Silencing of ILK can inhibit the scar formation after glaucoma filtering surgery and maintain low IOP in rats.

【Objective】 To investigate setup and respiratory movement residual error with the guidance of online four-dimensional cone beam computed tomography (4DCBCT) and the impact on margins required to internal target volume (ITV) margin during stereotactic body radiotherapy (SBRT) of lung tumor in the middle or lower lobe. 【Methods】 Twenty SBRT treatment patients with lung tumor in the middle or lower lobe were enrolled for treatment residual error retrospective analysis. Thermoplastic masks were used as immobilization devices during SBRT treatment. ITV was determined by 4DCBCT simulation. A total of 76 4DCBCT scans before the treatment were recorded to determine the setup and respiratory residual error for ITV margins. 【Results】 The setup and respiratory movement error were significantly reduced with the guidance of online 4DCBCT during radiotherapy. The setup residual errors were respectively (0.07±0.12)cm, (0.03±0.29)cm and (0.04±0.14)cm in right-left (RL), superior-inferior (SI) directions and anterior-posterior (AP) directions. The respiratory movement residual errors were respectively (-0.06±0.07)cm, (0.02±0.26)cm and (0.02±0.11)cm in RL, AP, and SI directions. Based on setup and respiratory movement residual errors, the PTV margins of NSCLC were reduced from 1.13 cm, 2.15 cm and 0.90 cm to 0.50 cm, 0.59 cm and 0.56 cm in RL, AP and SI directions, respectively, calculated with recipe by VanHerk. 【Conclusion】 With the guidance of online 4DCBCT, the setup and respiratory movement residual error cannot be ignored during SBRT of lung tumor in the middle or lower lobe. The ITV margin required after online 4DCBCT correction for the patients enrolled in the study would be approximatively 0.6 cm around to ensure an accurate dose to the target tumor and reduce the dose to normal tissues.

Objective:To observe the clinical efficacy of ultrasound cycloplasty (UCP) in the treatment of uncontrolled intraocular pressure (IOP) after glaucoma surgery.Methods:An observational case series study was carried out.Twenty-eight consecutive patients (28 eyes) with uncontrolled IOP after glaucoma surgery who received UCP treatment in The First Affiliated Hospital of Zhengzhou University from July 2018 to October 2019 were enrolled.The IOP of these patients was ≥21 mmHg (1 mmHg=0.133 kPa) under the maximum tolerated dose.According to preoperative IOP and visual acuity, the patients were divided into 8-sector group (17 eyes) and 10-sector group (11 eyes). The duration of UCP operation, preoperative and postoperative 1-day, 1-week, 2-week, 1-month and 3-month IOP and BCVA, the types of drugs for lowering IOP preoperatively and postoperatively, preoperative and postoperative 3-month ocular pain grading and corneal endothelial cell counts, and adverse reactions during the operation and after surgery were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2020-KY-154). Written informed consent was obtained from each subject prior to any medical examination.Results:The duration of UCP operation was 3 to 7 minutes, with an average of (4.30±1.26) minutes.The IOP at 1 day, 1 week, 2 weeks, 1 month and 3 months after operation was (32.96±10.49), (25.89±7.25), (24.50±6.23), (24.07±6.59), (24.32±6.52)mmHg, respectively, which were significantly lower than (45.82±8.81) mmHg before operation (all at P<0.05). There was no significant difference in IOP between the 8-sector group and 10-sector group ( Fgroup=1.271, P=0.270), but there was a significant difference in IOP between the two groups before and after operation ( Ftime=54.388, P<0.01), and the postoperative IOP at various time points in the two groups were lower than the preoperative IOP, showing statistical significances (all at P<0.05). There was no significant difference in BCVA before and after surgery ( F=2.562, P=0.075). There was a statistically significant difference in BCVA between the 8-sector group and 10-sector group ( Fgroup=12.602, P=0.001), but no statistically significant difference was found in BCVA between the two groups before and after surgery ( Ftime=1.701, P=0.139), and the BCVA in the 8-sector group was better than the 10-sector group at various time points (all at P<0.05). The types of IOP lowering drugs used in the 8-sector group and 10-sector group were 3 (2, 3) and 3 (2, 4) before operation respectively, and 0 (0, 1) and 0 (0, 0) at 3 months after operation respectively.The preoperative ocular pain grade was 2 (2, 2), and the postoperative 3-month ocular pain grade was reduced to 1 (0, 1), and the difference was statistically significant ( Z=-4.824, P<0.05). The postoperative 3-month pain grading in the 8-sector and 10-sector groups were significantly lower than the preoperative pain grading ( Z=-3.739, -3.127; both at P<0.05). The corneal endothelial cell count was significantly decreased from (1 967.15±186.06) cells/mm 2 before operation to (1 861.08±206.63) cells/mm 2 at 3 months after operation ( t=2.781, P=0.017). No serious complications occured during the operation.Postoperative adverse reactions included chemosis and bulbar hyperemia, corneal edema, headache, ocular pain, anterior chamber inflammation, etc.Serious complications such as low IOP, macular edema, vision loss or eyeball atrophy were not observed. Conclusions:UCP has no surgical incision.Treatment of both 8 sectors and 10 sectors can effectively reduce IOP, reduce the types of IOP lowering drugs, and relieve ocular pain in patients with uncontrolled IOP after glaucoma surgery with few intraoperative and postoperative adverse reactions.

Objective:To give some suggestions on the policy optimization of the establishment of National Hygienic City from the perspective of policy system.Methods:Policy documents were searched in WanFang Database and websites of ministries and commissions directly affiliated to the State Council with the key words of hygienic city, and analyzed by using the content analysis and quantitative analysis, based on the theory and perspective of policy tools and the two-dimensional analysis framework.Results:Among the 161 policy documents, supply-based, environment-based, and demand-based policy tools accounted for 6.83% (11/161), 83.85% (135/161), and 9.32% (15/161) respectively. Policy planning, policy implementation, policy supervision, and policy evaluation tools accounted for 10.56% (17/161), 63.35% (102/161), 21.74% (35/161), and 4.35% (7/161) respectively.Conclusion:The government should reduce its dependence on environmental policy tools, especially strategic measures, and attach importance to the use of supply-based policy tools and demand-based policy tools.

There were no statistical differences in the incidence of ADR between patients with Shire Yunfu type [OR ＝0.72，95％CI（0.21，2.41），P＝0.59]，Pixu Shiyun type [OR ＝0.31，95％CI（0.01，13.57），P＝0.54]，Xuexu Fengzao type [OR＝1.08，95％ CI（0.18，6.59），P＝0.93] in trial group and control group. After treatment ，the levels of TNF-α [SMD＝－1.67，95％CI（－2.04，－1.31），P＜0.000 01]，IL-6 [SMD＝－1.53，95％CI（－1.88，－1.17），P＜0.000 01] and IL-8 [SMD＝－1.75，95％CI（－2.28，－1.21），P＜0.000 01] in patients with Shire Yunfu type in trial group were significantly lower than control group. There was no statistical significance in CD 4+ levels [SMD ＝1.51，95％CI（－0.37，3.38），P＝0.12] between Shire Yunfu type patients in trial group and control group. CONCLUSIONS ：Therapeutic efficacy of classical prescription in treatment of eczema is better than antihistamines，with similar safety . Modified Longdan xiegan decoction can significantly reduce the levels of inflammatory cytokines in patients with Shire Yunfu type.

With the acceleration of the population aging in China, the health problems and the demands of health services such as health check-up for rural residents should attract the attention of the whole society. The group standard entitled Health check-up guide for rural residents (T/CHAA 005-2019), was written by experienced researchers from Chinese Center for Disease Control and Prevention and other professional institutes coordinated by Chinese Health Association. The standard aims to establish a service model that takes health information collection as a means, health risk assessment, health risk intervention and information services as the core, improving the health of rural residents as the target.

The study aims to investigate whether there is difference in pre-treatment white matter parameters in treatment-resistant and treatment-responsive schizophrenia. Diffusion tensor imaging (DTI) was acquired from 60 first-episode drug-naïve schizophrenia (39 treatment-responsive and 21 treatment-resistant schizophrenia patients) and 69 age- and gender-matched healthy controls. Imaging data was preprocessed via FSL software, then diffusion parameters including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) were extracted. Besides, structural network matrix was constructed based on deterministic fiber tracking. The differences of diffusion parameters and topology attributes between three groups were analyzed using analysis of variance (ANOVA). Compared with healthy controls, treatment-responsive schizophrenia showed altered white matter mainly in anterior thalamus radiation, splenium of corpus callosum, cingulum bundle as well as superior longitudinal fasciculus. While treatment-resistant schizophrenia patients showed white matter abnormalities in anterior thalamus radiation, cingulum bundle, fornix and pontine crossing tract relative to healthy controls. Treatment-resistant schizophrenia showed more severe white matter abnormalities in anterior thalamus radiation compared with treatment-responsive patients. There was no significant difference in white matter network topological attributes among the three groups. The performance of support vector machine (SVM) showed accuracy of 63.37% in separating the two patient subgroups ( = 0.04). In this study, we showed different patterns of white matter alterations in treatment-responsive and treatment-resistant schizophrenia compared with healthy controls before treatment, which may help guiding patient identification, targeted treatment and prognosis improvement at baseline drug-naïve state.

Objective:To investigate the effect of different cleaning methods on the cleaning effect of Da Vinci robotic electrosurgical instruments and the feasibility of adenosine triphosphate(ATP) fluorescence detection technology for evaluating the cleaning effect of Da Vinci robotic electrosurgical instruments.Methods:A total of 180 electrosurgical instruments were divided into control group and test group by random digits table method from June 2018 to June 2019 after robotic surgery. For the control group, 90 cases were manually cleaned to complete the device cleaning process, and for the test group, 90 cases were mechanically cleaned to complete the device cleaning process. Through visual observation, magnifying glass examination and ATP fluorescence detection technology, the cleaning effect of the two methods and the correlation between the evaluation results obtained by ATP fluorescence detection technique and traditional inspection method were compared.Results:The qualified rate of visual observation, magnifying lens examination and ATP fluorescence detection in the control group were 95.56%(85/90), 86.67% (78/90) and 84.44% (76/90), respectively, and that in the test group were 100.00% (90/90), 97.78% (88/90) and 98.89% (89/90), respectively. The test group was higher than the control group. The difference between the two groups was statistically significant ( χ2 values were 4.310, 7.745, 12.291, P<0.05 or 0.01). In the control group, there was a positive correlation between the qualified rate of ATP fluorescence detection and visual observation ( r value was 0.374, P < 0.01), and a significant positive correlation between the qualified rate of magnifying lens examination ( r value was 0.538, P < 0.01). In the test group, There was also a significant positive correlation between the qualified rate of ATP fluorescence detection and visual observation ( r value was 0.754, P < 0.01), and between the qualified rate of magnifying lens examination( r value was 0.556, P < 0.01). Conclusions:Mechanical cleaning is used to clean Da Vinci robotic electrosurgical instruments, which is superior to traditional manual cleaning. ATP fluorescence detection technology is feasible for evaluating the cleaning effect of Da Vinci robotic electrosurgical instruments.
