Objective To explore the related risk factors of non-alcoholic fatty liver disease (NAFLD) in Uygurs population of Xinjiang area.Methods A total of 966 Uygurs individuals undergoing physical examination in the First Affiliated Hospital and physical examination center of Xinjiang Medical University were collected and performed the questionnaire investigation,blood biochemical detection and B-type ultrasound examination;the subjects were divided into the NAFLD group (569 cases) and non-NAFLD group (397 cases) according to the physical examination situation.The NAFLD group was performed the correlation analysis of risk factors according to the body mass index (BMI) and waist to height ratio (WHtR) stratification.Results BMI and WHtR had statistical difference between the two groups(P＜0.05);overweight(OR =2.527,P＜0.05) and obesity(OR=1.938,P＜0.05) were the risk factors of NAFLD.The multivariate Logistic regression analysis showed that BMI,fasting plasma glucose (FPG) and triacylglycerol (TG) were associated with NAFLD(P＜0.05) and the risk factors of NAFLD.Conclusion BMI,WHtR,FPG and TG are the risk factors of NAFLD,and have a certain clinical significance in the evaluation and prediction of NAFLD high risk population.

OBJECTIVE:To provide references for the revision of pharmaceutical talents training plan in higher vocational colleges. METHODS:Selecting parts of freshmen,sophomores and junior students majoring in pharmacy in our hospital as subjects, questionnaires were conducted for the effect of hospital“pharmacy trusteeship”policy on their employment selection,and the results were statistically analyzed. RESULTS:Totally 190,390,320 questionnaires were received from junior students,sophomores and freshmen. The surveyed students knew less about“pharmacy trusteeship”policy,only a maximum by junior students of 35.79%(comparison of different grades P<0.05);while among the surveyed students from different career directions,the highest awareness rate about“pharmacy trusteeship”policy was from the students whose hospital pharmacy(41.30%-45.21%)(comparison of different career direction P>0.05). The career direction of hospital pharmacy had the highest proportion of surveyed students in each grade(38.42%-53.13%),especially the freshmen(comparison of different grades P<0.05,comparison of different career direction in a same grade P<0.05). But after knowing the policy,the surveyed students had the lowest recognition for the original career direction,especially the junior students(64.38%)(comparison of different career direction P<0.05). The surveyed freshmen and sophomores were firstly concerned the stability and then the welfare and income of the job,the surveyed junior students were firstly concerned the welfare and income and then authorized strength and the stability of the job. CONCLUSIONS:The pharmacy trusteeship policy has not yet been fully implemented,its effect on employment selection of higher vocational students majoring in pharmacy is relatively backward and the deeper effects have not been appeared completely.

Primary central nervous system lymphoma (PCNSL) is a kind of highly aggressive and rare extranodal non-Hodgkin lymphoma, and the treatment effect and survival prognosis of these patients are still not satisfied. In recent years, domestic and foreign researchers have devoted themselves to find more effective prognostic indicators from clinical hematological indicators, as well as gene and protein levels, so as to guide the diagnosis and treatment of PCNSL more accurately in clinical practice and improve the prognosis of PCNSL patients to a greater extent. This paper provides a review of such studies by reviewing PubMed.

The implementation methods were mainly regular disinfection, continuous disinfectionandregular combined with continuous disinfection. The concentration of disinfectant used for regular disinfection was 0.1%-10%, and the concentration of disinfectant used for continuous disinfection was 0.008%-0.250%. The commonly used evaluation index were the total number of colonies, qualified rate, pathogenic bacteria detection rate and biofilm.Conclusions:Both disinfectants can effectively control the pollution of DUWLs, and the antibacterial effect of hydrogen peroxide silver ion is better. It is possible to combine continuous and regular disinfection, regularly check the water quality of oral diagnosis and treatment, and adjust the disinfection strategy in time.

Objective: To explore the changes in the autophagy marker microtubule-associated protein 1 light chain 3 (LC3) and yeast autophagy-related gene 6 (Beclin1) in rat lungs exposed to free silica (SiO₂) dust for different periods. Methods: A total of 72 male specific pathogen-free Wistar rats were randomly divided into solvent control group and SiO₂ model group. The SiO₂ model group received one-time non-exposed intratracheal instillation of suspension of SiO₂ particles to establish a model of silicosis. The solvent control group received an equal amount of saline. Six rats each were sacrificed at 1, 7, 14, 21, 28, and 60 days after model establishment. The pathological changes and fibrosis of rat lungs at different time points were evaluated by H&E staining and Masson staining, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of transforming growth factor-β (TGF-β) , interleukin-1 (IL-1) , and tumor necrosis factor-α (TNF-α) in lung tissue homogenate. Western blot was used to determine the relative expression levels of LC3 and Beclin1 in the lung tissue. Results: The results of H&E staining showed that the model group had continuous inflammation in the lung tissue from day 1 to day 60, and the inflammatory scores were significantly higher in the model group than in the control group (P<0.05) . The results of Masson staining showed that rats in the model group had a small amount of collagen fibers in the lung tissue on day 14 and a large amount of collagen fibers on day 60. The fibrosis score was significantly higher in the model group than in the control group (P<0.05) . No collagen fibrosis was observed in the lung tissue in the control group. The results of ELISA showed that the model group had significantly higher levels of IL-1, TNF-α, and TGF-β in lung tissue homogenate than the control group at each time point after exposure (P<0.05) . The results of Western blot showed that the model group had decreased expression of Beclin1 protein in the lung tissue on days 7, 14, 21, 28, and 60, which was significantly higher than that of the control group (P<0.05) . The model group also had a decreased ratio of LC3II/LC3I on days 1, 7, 14, 21, 28, and 60, which were significantly higher than that of the control group (P<0.05) . Conclusion In the rat model of silicosis induced by free SiO₂ dust, the expression levels of autophagy-related proteins, LC3 and Beclin1, are correlated with different stages of silicosis. In the early stage of silicosis, the lung tissue has inflammation, substantially increased ratio of LC3II/LC3I and expression of Beclin1, and active autophagy. With the progression of silicosis, the ratio of LC3II/LC3I and expression level of Beclin1 gradually decrease and autophagy becomes weak.

Objective:To explore the effect of ICX ? tablets on controlling the pollution of dental unit waterlines. Methods:From September 30, 2018 to February 23, 2019, convenience sampling was used to select dental chair unit (DCU) with the dental pulp professional brand of A-dec which was newly put into use in a stomatology hospital for numbering. Using the method of random number table, four DCUs were selected and included in this study, including two in experimental group and two incontrol group. In control group, distilled water was added into two DCUs in dependent water storage tanks. In experimental group, two DCUs independent water storage tanks were added with distilled water and ICX ? tablets. From the first day of clinical use, water samples were collected continuously for 7 days, and the ICX ? tablets group was continuously sampled for 12 weeks for bacterial culture, and the number and qualified rate of colonies were counted. Results:A total of 280 water samples were collected.The number of colonies at the water outlet of the new DCU that used distilled water added with ICX ? tablets as dental unit waterlines was lower than that of distilled water group from the first day, and the difference was statistically significant ( P=0.007) . The qualified rate of colony number at the water outlet of the new DCU that used distilled water added with ICX ? tablets as dental unit waterlines was higher than that of distilled water group from the second day, and the difference was also statistically significant ( P=0.007) . Conclusions:ICX ? tablets can effectively control the pollution of dental unit waterlines and can keep the number of colonies in dental unit waterlines at a low level for a long time, but it still needs to be combined with regular monitoring and enhanced disinfection.

Objective:To explore the associations between perceived built environment attributes and adults’ leisure-time physical activity in four cities of China.Methods:Multistage cluster random sampling method was used to select adults aged 25 to 64 in Hangzhou, Suzhou, Chengdu, and Qingdao. Data were collected from June 2017 to July 2018. The perception of the urban built environment was assessed by the neighborhood environment walkability scale-abbreviated (NEWS-A), and the physical activity was assessed by the International Physical Activity Questionnaire. Generalized linear mixed models were used to explore the relationship between the perceived built environment and leisure-time physical activities.Results:A total of 3 789 participants were included in the analysis. After adjusting for potential confounders, better access to public services ( OR=1.34, 95% CI: 1.02-1.75) and higher aesthetic quality ( OR=1.37, 95% CI: 1.09-1.73) were positively associated with the possibility of engaging in leisure-time physical activity in the past week. Similarly, these two attributes were positively associated with leisure-time walking. Higher scores on the perception of street connectivity were positively associated with leisure-time walking [ exp( β)=1.09, 95% CI: 1.00-1.19]. Higher residential density [ exp( β)=1.000 4, 95% CI:1.000 0-1.000 8], better access to physical activity destinations[ exp( β)=1.09, 95% CI: 1.00-1.19], and better aesthetics [ exp( β)=1.11, 95% CI:1.00-1.22] were associated with higher leisure-time physical activity. Similarly, these three attributes were positively associated with the possibility of meeting the WHO recommendations. Conclusion:Changing some urban built environment attributes may increase leisure-time physical activity.

Objective:To analyze the thalassemia screening and genotyping in Southwest Guizhou Autonomous Prefecture (referred it as Qianxinan Prefecture), this essay provides the theoretical reference for clinical diagnosis of thalassemia and suspicious cases.Methods:The pregnant women, spouses and neonates who were screened for thalassemia gene in Qian Xi Nan People's Hospital from January 2016 to December 2020 were selected as the research subjects, and peripheral blood or umbilical cord blood samples were collected to extract DNA. The gap-polymerase chain reaction (Gap-PCR) and next-generation sequencing (NGS) technology were used to screen thalassemia, and ArcMap 10.8 software was adopted to map the local spatial distribution of thalassemia based on the screening data.Results:A total of 67 185 cases of people from various regions in Qianxinan Prefecture were screened, and 8 202 cases of thalassemia gene carriers were detected, with a total detection rate of 12.21%. Among them, 5 660 cases of α-thalassemia, with a detection rate of 8.42%; 2 132 cases of β-thalassemia, with a detection rate of 3.17%; 410 cases of αβ complex thalassemia, with a detection rate of 0.61%. In the detection of thalassemia genes, 27 genotypes of α-thalassemia were detected, mainly αα/-α 3.7, accounting for 41.13% (2 328/5 660); 33 genotypes of β-thalassemia were detected, mainly β CD17(A>T)/β A, accounting for 44.09% (940/2 132); 55 genotypes of αβ complex thalassemia were detected, and αα/-α 3.7 complexed β CD17(A>T)/β A dominated, accounting for 21.22% (87/410). There were high incidence areas in the spatial distribution of thalassemia, which were Wangmo County and Ceheng County, and the detection rate was 26.76% (1 438/5 374), 24.39% (1 314/5 387), respectively. Conclusions:The detection rate of thalassemia gene in Qianxinan Prefecture is relatively high, mainly αα/-α 3.7 genotype of α-thalassemia. Wangmo County and Ceheng County are high-incidence areas of thalassemia, and screening efforts should be continued.

Objective:To investigate the electrophysiological features of patients with anti-neurofascin 155 (NF155) IgG4 antibodies positive chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).Methods:The electrophysiological data of 6 anti-NF155 IgG4 antibodies positive CIDP patients in Beijing Tiantan Hospital, Capital Medical University from September 2018 to May 2021 were retrospectively analyzed. Parameters studies included standard motor and sensory nerve conduction studies, electromyography (EMG) and F waves studies. Correlation analysis was made to explore the relationships between clinical indicators and electrophysiological data.Results:There was statistically significant difference in the motor nerve conduction study on abnormal rate of tibial nerve (χ 2=11.08, P=0.011). Motor nerve conduction abnormalities were presented in a majority of patients with decreased motor conduction velocity (MCV) and prolonged distal motor latency (DML). There was no statistically significant difference in the overall abnormal rate between lower limbs and upper limbs (30/32, 93.8% vs 22/22, 100.0%; χ 2=1.43, P=0.508), sensory nerve conduction and motor nerve conduction (52/54, 96.3% vs 42/42, 100.0%; χ 2=1.59, P=0.503). There was statistically significant difference in the overall abnormal rate in median nerve, ulnar nerve and sural nerve (χ 2=14.96, P=0.001;χ 2=10.00, P=0.007; χ 2=9.95, P=0.008),and absent sensory nerve action potential was the most common abnormality in sensory nerve conduction abnormalities. The abnormal rate of EMG was 9/14, which was constituted by upper limbs (4/8) and lower limbs (5/6), and the spontaneous activity accompanied with prolonged duration and increased amplitude of motor unit action potential was common. Significant negative correlations were established between disease duration and compound muscle action potential (CMAP) amplitude and negative area of ulnar nerve ( r=-0.84, P=0.036; r =-0.76, P=0.011), and the correlations between age and MCV of median nerve and ulnar nerve were also found ( r=0.89, P=0.019; r=0.95, P=0.003). The DML of median nerve was negatively correlated with CMAP amplitude ( r=-0.63, P=0.049). Moreover, the correlation analysis revealed associations of the F wave latency with the DML, CMAP amplitude and MCV of tibial nerve ( r= 0.90, P=0.039; r=-0.96, P=0.012; r=-0.96, P=0.010). Conclusions:The motor nerve and sensory nerve, the myelin sheath and axon of peripheral nerves in anti-NF155 IgG4 CIDP patients were largely affected. The CMAP amplitude and negative area of ulnar nerve might be of certain clinical value in reflecting the disease duration.The younger the patients, the more severe the demyelination degree of the upper limbs. The F wave latency of tibial nerve not only reflected the abnormal proximal conduction, but also the distal damage degree of myelin sheath and axon.
