Objective To investigate the effect and mechanism of miR-20a-5p on human nephroblastoma cell line WiT49 transplanted tumor in nude mice.Methods The gene expression chip was downloaded from GEO database,and the differential gene miR-20a-5p was obtained by GEO2R.The NF-κB gene was positively correlated with the expression of miR-20a-5p through cBioPortal database.The target gene of miR-20a-5p was predicted to be NFKBIB of the NF-κB transcription factor suppressor protein family by targetscan database,and was verified by dual luciferase assay.Nephroblastoma cell line WiT49 was cultured in vitro and transfected into WiT49 cells with lentiviral vectors constructed with miR-20a-5p mimics and its suppressor gene.Twelve nude mice were randomly divided into three groups:WiT49 model group,WIT49-miR-20a-5p overexpression group and WIT49-miR-20a-5p knockdown group.The tumor mass and volume of each group were detected by tumor formation experiment in nude mice.real time fluorescent quantitative polymerase chain reaction(qRT-PCR)was used to detect the expression of miR-20a-5p,NFKBIB and NF-κB in each group;CCK-8 cell proliferation assay was used to verify the proliferation of tumor cells in each group.Results miR-20a-5p is highly expressed in nephroblastoma and is positively correlated with the expression of NF-κB.miR-20a-5p and NFKBIB have mutual binding sites and binding effects.In the tumor formation experiment of nude mice,the tumor volume and mass of WIT49-miR-20a-5P overexpression group were significantly increased compared with WiT49 model group,and the difference was statistically significant(P<0.05).In the qRT-PCR test,the expressions of miR-20a-5p and NF-κB in the WIT49-miR-20a-5p overexpression group were higher than those in the WiT49 model group,and NFKBIB expression in the WIT49-miR-20a-5p overexpression group was lower than that in the WiT49 model group,with statistical significance(P<0.05).CCK-8 cell proliferation assay showed that the absorbance of WIT49-miR-20a-5p overexpression group at 24 and 48 hours was higher than that of WiT49 model group,and the absorbance of WIT49-miR-20a-5p knockdown group at 24,48 and 72 hours was lower than that of WiT49 model group,and the difference was statistically significant(P<0.05).Conclusion miR-20a-5p may promote the growth of human nephroblastoma cell WiT49 transplanted tumor in nude mice by regulating NFKBIB activation of NF-κB pathway.

Objective To retrospective analyze the drug characteristic and clinical effect of Uygur medicine for treating insomnia. Methods Totally 234 cases of insomnia in hospitalized records were selected by record statistical system of HIS. Patients’ general conditions, Uygur medicine utilization rate, combination medication, pathogenic humoral, treatment course and therapeutic effect were retrospectively analyzed. Results Insomnia patients were mainly 30-60 years old (81.82%). Abnormal Sawda and Balgam were the main pathogenic humoral, accounted for 54.27% and 28.63% respectively. And 85 kinds of preparation were involved, including Yinao Wusiti Kudousi syrup and Muniziqii Sawda mixture, 213 and 163 times of frequency (91.03% and 69.66%) respectively. Most of patients used 5-12 kinds of preparation, accounted for 89.13%, and treated for one week to one month, accounted for 73.16%. Conclusion The Uygur medicine for insomnia is unique, and has good clinical efficacy and safety.

Objective To investigate the iodine nutritional status of school children, lactating women and infants in iodine deficient areas of Baicheng and Wushi Counties in Xinjiang Autonomous Region. Methods According to the geographic location of east, south, west and north of county, 10 primary schools of 8 townships were selected. In each school, 10 children among each gender and age group from 8 to 10 years old were selected. A total of 300 school children were chosen. One hundred and four infants aged 0-2 years old and their mother were selected in 8 townships. Iodine content in edible salt at household level, the urinary iodine in school children and lactating women, total goiter rate(TGR) and the status of the intelligence quotient (1Q) of school children, the status of psychological development of infants were observed. Direct titration assay for testing the salt iodine, colorimetric ceric-arsenic assay and vitriolic ammonium assimilation were used for testing urinary iodine. The size of thyroid gland was measured by palpation. The Combined Raven Test for Chinese Rural was used to test the IQ. The psychological development of infants was tested by Danver Development Screening Test (DDST). Results The coverage rate of iodized salt at household level was 73.1% (123/182), however, the proportion of households using adequately iodized salt was 64.1% (118/182). The medium of urinary iodine in school children was 103.7 μ/L, with 47.8%(75/157) less than 100 μg/L and 28.0% (44/157) less than 50 μg/L; it was 123.0 μg/L in Baieheng County, with 44.4%(28/63) less than 100 μg/L and 33.3%(21/63) less than 50 μg/L; it was 100.3 μg/L in Wushi County, 50.0%(47/94) less than 100 μg/L and 24.5%(23/94) less than 50 μg/L. The medium of urinary iodine in locating women was 143.3 μg/L, it was 119.7 μg/L and 184.6 μg/L in Baicheng and Wushi Counties, respectively. The total rate of goiter in school children was 14.3%(43/300), it was 10.8%(13/120) and 16.6%(30/180) in Baicheng and Wushi Counties, respectively. The average IQ in school children was 80.6±11.6, it was 83.0±11.6 and 79.0±11.7 in Baicheng and Wushi Counties, respectively. The proportion of mental retardation in school children (IQ≤69) was 13.0% (39/300), it was 6.7% (8/120) and 17.2%(31/180) in Baicheng and Wushi Counties, respectively. In addition, the proportion of psychological development in infants being normal, suspicious and abnormal was 78.8%(82/104), 12.5% (13/104) and 8.7%(9/104), respectively. Conclusion This study confirms the fact that there is also existence of mental retardation in children and infants, caused by iodine deficiency.

Objective To explore an effective treatment for benign prostatic hyperplasia complicated with bladder stones.Methods Swiss LithoClast Master and transurethral resection of the prostate(TURP)were performed on 33 patients with benign prostatic hyperplasia complicated with bladder stones.Results The operations were completed successfully in all the cases with a mean lithoclasty time of 35 min(15-65 min),and mean TURP time of 85 min(50-110 min).No blood transfusion,TUR syndrome,bladder perforation,or residual stone occurred during and after the operations.Urethral catheter was withdrawn 5 days postoperation,none of the patients had urinary incontinence or dysuria.The diagnosis of benign prostatic hyperplasia was confirmed by pathology examination.Three months after the operations,IPSS decreased from 23.4?5.2 to 7.4?1.2(t=3.732,P=0.000);maximum urinary flow rate increased from(5.4?1.5)ml/s to(18.6?3.2)ml/s(t=2.491,P=0.015);and QOL decreased from 3.9?1.2 to 2.0?0.7(t=2.454,P=0.014).Conclusions EMS LithoClast Master combined with TURP is an effective treatment for benign prostatic hyperplasia complicated with bladder stones.
