Objective To investigate the epidemiological characteristics and risk factors of non-alcoholic fatty liver disease in Jincheng between 2015 and 2020. Methods Clinical data of 8,578 medical check-ups at Physical Examination Center of ou hospital from January 2015 to December 2020 were retrospectively selected. The prevalence of non-alcoholic fatty liver disease in the last 5 years was recorded, and Logistic regression was utilized to identify the risk factors for the development of non-alcoholic fatty liver disease. Results The overall prevalence of non-alcoholic fatty liver disease in Jincheng was 14.57% in 2015-2020. The prevalence of non-alcoholic fatty liver disease was higher in men than in women (16.99% vs 10.98%) and highest in the 40-59 age group (18.76%). No statistical difference was reported in blood urea nitrogen (BUN) and serum creatinine (Scr) between groups (P>0.05), while statistical difference was found in diabetes, hypertension, body mass index (BMI), waist circumference, weekly exercise frequency, daily vegetable intake, triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT) and uric acid (UA) between two groups (P<0.05). Multivariate Logistic regression analysis denoted that BMI (OR=2.794, 95% CI: 1.745-4.550), waist circumference (OR=2.586, 95% CI: 1.585-4.299), diabetes (OR=0.644, 95% CI: 1.425-2.781), hypertension (OR=1.479, 95% CI: 1.121-2.290), weekly exercise ≥6h (OR=0.617, 95% CI: 0.519-0.709), daily vegetable intake ≥300g (OR=0.590, 95% CI: 0.467-0.652), TG (OR=1.481, 95% CI: 1.122-1.996), TC (OR=1.562, 95% CI:1.143-2.135), LDL-C (OR=1.440, 95% CI: 1.139-2.048), HDL-C (OR=0.656 , 95% CI: 0.587-0.783) , ALT (OR=1.591, 95% CI: 1.056-2.183), and UA (OR=1.412, 95% CI: 1.009-1.887) were risk factors for non-alcoholic fatty liver disease (P<0.05) . Conclusion The prevalence of non-alcoholic fatty liver disease in Jincheng City from 2015 to 2020 is 14.57%, the prevalence of males is higher than that of females, and the prevalence rate is the highest in the 40-59 age group. Moreover , diabetes mellitus , hypertension , BMI , waist circumference , weekly exercise , daily vegetable intake , serum TG, TC, LDL-C, HDL-C, ALT, and UA are all associated with the risk of the disease.

OBJECTIVE: To report on a case with severe hemophilia A (HA) due to a large duplication of F8 gene. METHODS: Inversion detection, Sanger sequencing, and multiplex ligation-dependent probe amplification (MLPA) were used to detect the mutation in the proband and his mother. RESULTS: The patient, a 7-year-old boy, was diagnosed with severe HA at 8 months. No inhibitor was developed over 150 exposure days. Intronic inversion detection and Sanger sequencing have failed to identify pathogenic variants, while MLPA revealed a large duplication [Ex 1_22 dup (2 copies)] in the proband, for which his mother was a carrier [Ex 1_22 dup (3 copies)]. Large duplications of the F8 gene have so far been found in 24 HA patients, all of whom had a severe phenotype, only one had a history of inhibitors. CONCLUSION Large duplications of F8 gene are associated with severe HA. The diagnostic rate for HA may be increased by MLPA.

Objective:To investigate the influencing factors of delayed methotrexate (MTX) elimination after high-dose methotrexate (HD-MTX) treatment in children with acute lymphoblastic leukemia (ALL) and the effects of delayed MTX elimination and HD-MTX reduction on the prognosis of children with ALL.Methods:The clinical data of 242 children with ALL diagnosed and treated in Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology from January 2015 to June 2020 in accordance with the Chinese Children's Cancer Group study ALL 2015 (CCCG-ALL 2015) were retrospectively analyzed. Low risk and intermediate/high risk children respectively received 3 g/m 2 and 5 g/m 2 HD-MTX for 4 times, and the serum MTX concentration was monitored. The serum MTX concentration > 1 μmol/L at 44 h of administration was considered as the delayed elimination, which was divided into mild (> 1 μmol/L and ≤ 5 μmol/L), moderate (> 5 μmol/L and ≤ 10 μmol/L) and severe (> 10 μmol/L) delayed elimination. Univariate and multivariate logistic regression analysis were used to analyze the influencing factors of delayed MTX elimination, and univariate Cox proportional hazards model was used to analyze the related factors of ALL relapse. Results:The 242 children with ALL completed 962 times of HD-MTX chemotherapy. The median serum MTX concentration [ M ( Q1, Q3)] at 44 h of administration was 0.45 μmol/L (0.33 μmol/L, 0.72 μmol/L). The total incidence of delayed MTX elimination was 17.7% (170/962). The incidence of mild, moderate and severe delayed elimination was 13.8% (133/962), 2.6% (25/962) and 1.2% (12/962), respectively. Logistic regression analysis showed that age ≥ 7 years old ( OR = 1.68, 95% CI 1.17-2.41, P = 0.005), MTX dose >3 g/m 2 at each course ( OR = 2.14, 95% CI 1.52-3.03, P < 0.001) and the first course of HD-MTX chemotherapy ( OR = 2.05, 95% CI 1.43-2.93, P < 0.001) were independent risk factors for delayed MTX elimination. The median follow-up time was 50 months (34 months, 68 months), 12.8% (31/242) of the children relapsed, and the median relapse time was 30 months (30 months, 39 months). Univariate Cox regression analysis showed that there were no significant differences in the relapse rates among children with different gender, immunophenotype, risk, the number of delayed MTX elimination, and the completion of HD-MTX chemotherapy (the ratio of MTX average dose to initial planned dose) (all P > 0.05). Conclusions:The independent risk factors of delayed elimination of MTX in children with ALL are age ≥ 7 years old, MTX dose > 3 g/m 2 at each course and the first course of HD-MTX chemotherapy. Delayed elimination of MTX and reduction of HD-MTX have no significant effect on ALL relapse.

Objective To explore the effects of combined exercise program ( fun game + rope skip-ping + figure running) on executive function ( EF) in primary students with Chinese learning difficulties. Methods Fifty-four Chinese learning disabled students were selected and randomly divided into experimen-tal group and control group. Three tasks ( the Flanker task,the 1-back task and the More-odd shifting task) were used to measure pupil’ s EF ( inhibition,updating,shifting) . Results ( 1) Compared with the control group,the primary students with Chinese learning difficulties in experimental group showed a significant en-hancement in executive function (F(1,43)=9.45, P<0.01). (2) The positive effects of 10 weeks combined ex-ercise program on executive function in primary students with Chinese learning difficulties were different. Specifically,a beneficial effect on updating(F(1,43)= 11.37, P<0.01) was got,but there were no significant effects on inhibition (F(1,43)=1.52, P>0.05) and shifting(F(1,43)=2.57, P>0.05). Conclusion The effect of combined exercise program ( fun game+rope skipping+figure running) plays a positive role in promoting updating function of primary school students with Chinese learning difficulties.

OBJECTIVE: To evaluate the extent of endolymphatic hydrops as shown by three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D FLAIR MRI) performed 24 hours after bilateral intratympanic gadolinium administration and discuss the positive rate of endolymphatic hydrops in vestibule and cochlea. METHOD: Twenty-four hours after bilateral intra-tympanic 8 times diluted gadolinium administration, three-dimensional fluid-attenuated inversion recovery MRI, using a three-Tesla unit, was performed in 48 patients, and then assessed the extent of endolymphatic hydrops in the MRI images. RESULT: Forty-eight patients showed different levels of enhancement of perilymth in the inner ear. In these patients, obvious signs of endolymphatic hydrops were visualized in vestibule,including 8 slight hydrops, 17 mild hydrops and 23 severe hydrops with a diagnostic rate of 83.3%. There were almost no complications in all 48 patients after bilateral intra-tympanic injection except short vertigo in some of them. CONCLUSION 3D FLAIR MRI resonance imaging has a high positive diagnostic rate in assessing endolymphatic hydrops of Ménière's disease and provides direct imaging evidence for diagnosing Ménière's disease.

A total of 78 patients were recruited from Department of Orthopedics in the Fourth Affiliated Hospital of Guangxi Medical University from January to June in 2008.Forty patients admitted in odd day,and they received the therapy of vacuum sealing drainage including vacuum sealing drainage to dress wound and semipermeable film for vacuum aspiration,namely curing group;38 patients' hospital admission time was in even day,and they underwent a common therapy to dress a wound again,namely control group.Two groups of patients were compared addressing the free skin grafting,skin flap transfer or free skin flap transplantation.Results showed that the healing ratio of the curing group was higher,it's infection rate was lower,and the length of hospital stay was also shorter than the control group.Vacuum sealing drainage is a better method in clinical medicine to cure the refractoriness raw surface.

Objective To investigate the relationship between growth inhibiting effect of arsenic trioxide(As_2O_3) and phosphorylation of P27kip threonine residue 187(P27T187) in human hepatocellular carcinoma(HCC) cell line SMMC-7721.Methods SMMC-7721 were treated for 72 h with 2 ?mol/L As_2O_3.The cell growth inhibition was detected by cell counting and the cell cycle was detected by flow cytometry(FCM).The expression and localization of P27,T187 phosphorylated P27(p-P27T187) were detected by Subcellular Fractionation,Western blot and immunoflurescence.Results As_2O_3 significantly inhibited the proliferation of SMMC-7721 cell and cell cycle was arrested in G2/M.A significant decrease in p-P27T187 expression and a reciprocal increase in P27 expression were found in 2 ?mol/L As_2O_3-treated SMMC-7721 cell.Meanwhile,As_2O_3 decreased the protein levels of Cdk2 and cyclinE.The location of P27 was transferred from cytoplasm to nuclei and the expression of p-P27T187 was decreased in nuclei.Conclusion As_2O_3 inhibits the phosphorylation of P27T187,thereby promoting P27 accumu-lation in SMMC-7721 cell nuclei,inducing cel1 cycle arrest and growth inhibition.

Objective To investigate the expression of C-JUN activation domain binding protein 1(JAB1)and its relationship with expression of P27 protein in human hepatocellular carcinoma(HCC),and to determine whether JAB1 is associated with clinicopathological parameters and prognosis of HCC.Methods Immunohistochemical analysis was performed to investigate the expression of JAB1 and P27 in 76 cases of HCC and adjacent nontumorous tissues.Fresh tumor tissues and their adjacent nontumorous tissues from 8 cases of HCC were collected for Western blot and immunoprecipitation assays.Results The expression of JAB1 in HCC was significantly higher than that in adjacent nontumorous tissues.In contrast,P27 level was higher in nontumorous liver tissues than that in HCC.JAB1 overexpression was correlated with histological differentiation,serum alpha-fetoprotein(AFP)level and metastasis(P

OBJECTIVETo observe the ultrastructures of rat alveolar type II cells and change of composition of phospholipid(PL) and content of protein in pulmonary surfactant(PS), to investigate the relation between change in composition of PL and activity of alveolar type II cells.

METHODSThe rats lung injury models were made by intratracheally instilling bleomycin(BLM) (4 mg/ml, 5 mg/kg). 28 rats were divided into four groups: 3-day group, 7-day group, 14-day group and 28-day group. Preparations of each group were stained histochemically and examined by electron microscope, content of PL in BALF, composition of PL and content of protein of each group were determined respectively.

RESULTS(1) Rats lungs in experimental groups were found that PS lost continuously, appeared homogenous and chorionic, dropped in the pulmonary alveolies. 3-day group was more apparent. Ruthenium red attaching on pulmonary surfactant was thicker in 3-day group, and the colour deeper, no difference in 7-day group and 14-day group, thinner in 28-day group. Content of PL in PS of BALF was increasing. Content of phosphatidylglycerol(PG) increased in 3-day group, decreased in 7-day, 14-day and 28-day group. The change of content of phosphatidylinositol(PI) was reversed. (2) Alveolar type II cells degenerated, necrotized, even disintegrated in 3-day group and 7-day group. 3-day group was more apparent. Proliferations of alveolar type II cells were found in each group, 7-day group was more apparent. We found that type II cells transformed to type I cells in 14-day group, extended and attached on bare basement membrane. Content of protein in PS was the highest in 3-day group, almost equal to the content of the control group in 28-day group.

CONCLUSIONMorphologic change and alternation of quality and quantity of PS after bleomycin-induced pulmonary injures specifically reflect the activity of alveolar type II cells. Measuring content of PL in BALF is one of simple and feasible method judging activity of alveolar type II cells when lungs of the rats are injured early by bleomycin.
