The effect of rhGM-CSF/IL-3 on apoptosis of Ara-C-induced myeloid leukemic cell line HL- 60 was investigated. The results indicated that treatment with rhGM-CSF/IL-3 in combination with Ara-C significantly inhibited the colony growth of HL-60 and enhanced the oligonucleosomal DNA fragmentation as compared with Ara-C alone. The Ara-C mediated apoptosis rates of HL-60 cells treated with rhGM-CSF/IL-3 fusion protein alone were markablely improved compared with treatment with rhIL-3 plus rhGM-CSF, it was noted that the Ara-C mediated of apoptosis normal peripheral white blood cells was less affected by rhGM-CSF/IL-3. It suggested that rhGM-CSF/IL-3 could be used as a possible curing drug during the phase of induced remission of leukemia.

Objective: To evaluate the effect of NGX6 with 5-Fu on the apoptosis of colon cancer cells. Methods: The NGX6-transfected HT-29 cell line with 5-Fu was used in the test group. HT-29 cell line with 5-Fu and PDTC was used in the control group. The expression of NF-κB was detected by EMSA. The proliferation of HT-29 cell line was assayed by MTT. The effect of NGX6 on the apoptosis was detected by FCM. HT-29 cells were double-stained by PI/Annexin-V and AO/EB and observed by fluorescence microscopy. Results: The expression of NF-κB was inhibited in NGX6 transfected colon carcinoma cell group and in colon carcino-ma cell group treated with PDTC. Treatment with the chemopreventive compounds 5-Fu and PDTC resulted in different responses in the effects of anti-proliferation and induced apoptosis of colon carcinoma cells. There was no significant difference in apoptosis between NGX6-transfected HT-29 call line with 5-Fu and the cells in the control group. NGX6 gene enhanced the effect of 5-Fu on the proliferation and apoptosis of colon carcino-ma cells. Conclusion: NGX6 gene can induce apoptosis and inhibit the proliferation of colon carcinoma cells. NGX6 gene can enhance the effect of 5-Fu on the proliferation and apoptosis of colon carcinoma cells through NF-κB pathway.

OBJECTIVE: To evaluate 3 published questionnaires for screening diabetes for rural samples in China. METHODS: Three screening questionnaires (Finnish Diabetes Risk Score, Danish Diabetes Risk Score, and Chinese Diabetes Risk Score) were selected through literature review, and were employed in a rural community sample in Wangcheng, Changsha. RESULTS: Sensitivity of these risk scores was 63.72%, 56.64% and 82.30%; the specificity was 79.75%, 62.64% and 46.90%. The area under the receiver operating characteristic curve (AUC) was 0.78 (95% CI: 0.73-0.83), 0.65 (95% CI: 0.60-0.70) and 0.68 (95% CI: 0.63-0.73). CONCLUSION The 3 screening questionnaires show a lower validity than originally described when applied to rural samples in the study. Difference in population characteristics is a possible reason. F-DRS is better than the other two, suggesting that F-DRS is more suitable for diabetes screening in China rural areas.

Background In recent years, the incidence of metabolic syndrome (MS) is increasing significantly in China. Some studies have found that temperature is related to single metabolic index, but there is a lack of research on associated mechanism and identifying path of the influence of temperature on MS. Objective Based on the data of Guangdong Province, to investigate the effect of temperature on MS and its pathway. Methods A total of 8524 residents were enrolled by multi-stage random sampling from October 2015 to January 2016 in Guangdong. Basic characteristics, behavioral characteristics, health status, and physical activity level were obtained through questionnaires and physical examinations, and meteorological data were obtained from meteorological monitoring sites. We matched individual data both with the temperature data of the physical examination day and of a lag of 14 d. A generalized additive model was used to explore the exposure-effect relationship between temperature and MS and its indexes, calculate effect values, and explore the effects of single-day lag temperature. Based on the literature and the results of generalized additive model analysis, a path analysis was conducted to explore the pathways of temperature influencing MS. Results The association between daily average temperature on the current day or lag 14 day and MS risk was not statistically significant. When daily average temperature increased by 1 ℃, the change values of fasting blood-glucose (FBG), systolic blood pressure (SBP), diastolic blood pressure (DBP), and high density lipoprotein cholesterol (HDL-C) were −0.033 (95%CI: −0.040-−0.026) mmol·L⁻¹, −0.662 (95%CI: −0.741-−0.583) mmHg, −0.277 (95%CI: −0.323-−0.230) mmHg, and −0.005 (95%CI: −0.007-−0.004) mmol·L⁻¹ respectively. The effects of average daily temperature on FBG, blood pressure, HDL-C, and waist circumference lasted until lag 14 day. The effects of daily average temperature on SBP and DBP were the largest on the current day. Daily average temperature of current day had direct and indirect effects on FBG and SBP. Temperature had an indirect effect on TG, and the intermediate variables were waist circumference and FBG, with an indirect effect value of −0.011 (95%CI: −0.020-−0.002). The indirect effects of daily average temperature on SBP, FBG, and TG were weak. Conclusion There is no significant correlation between temperature and risk of MS, and daily average temperature of current day could significantly affected blood pressure and FBG with a lag effect. Daily average temperature of current day has indirect effects on FBG and TG.

Objective To analyze the status of hepatitis B and BCG vaccination in children with special health status, and analyze the reasons for the delay of vaccination, so as to improve the timely vaccination rate. Methods A total of 1 129 children with special health status who were registered and vaccinated in our hospital from September 1, 2018 to January 23, 2020 were selected. All children were classified according to the major diseases based on the discharge records. The first injection time of hepatitis B and BCG vaccine was extracted, and the children were divided into different groups based on the number of people who delayed vaccination. The comparison between groups was performed by χ² test. Results A total of 87 children without hepatitis B vaccination and 85 children without BCG vaccination were immediately vaccinated in our hospital after the establishment of the archives in our hospital. None of the 1 129 children with special health status had serious adverse reactions after vaccination. The most common diseases in the delayed hepatitis B vaccination children were premature infants, cardiovascular diseases, and nervous system diseases. The most common diseases in the delayed BCG vaccination children were premature infants, cardiovascular diseases, and neonatal disease. There was a significant difference between the number of delayed hepatitis B vaccination and the number of delayed BCG vaccination, with the number of delayed BCG vaccination being more (χ²=278.24, P<0.00). Conclusion Delayed vaccinations are common in children with special health status. Normal vaccination does not increase the incidence of adverse reactions in children with special health status. Medical staff’s understanding of diseases, types of diseases, and types of vaccines are important factors affecting the vaccination of children with special health conditions. Support from social environment, the understanding and cooperation from children's parents and guardians, and the understanding of medical workers on vaccines and diseases are the keys to truly improve the vaccination rate of children..

The research team on the National Key Scientific Program of China: "Transcriptomic regulation and molecular mechanism research of polygenic tumor at different stages" has focused on the field of transcriptomics of 4 common polygenic tumors, including nasopharyngeal carcinoma(NPC), breast cancer, colorectal cancer, and glioma. Extensive laboratory work has been carried out on the expression and regulation of tumor transcriptomics; identification of tumor suppressor/susceptible genes; mechanism of tumor epigenetics including miRNAs, and comparative study of specific gene/protein cluster of tumor transcriptomics and proteomics. Genes including SPLUNC1, LTF, BRD7, NOR1, BRCA1/2, PALB2, AF1Q, SOX17, NGX6, SOX7, and LRRC4 have been identified as the key transcriptional regulation genes during the stage of tumor initiation and invasion. Accordingly,the NPC gene signal regulation network of "SPLUNC1-miR-141-target genes", the breast cancer interaction signal pathway of "miR-193b-uPA",the glioma signal network of "miR-381- LRRC4-MEK/ERK/AKT", and the miRNA-target gene network of colorectal cancer metastasis related gene NGX6 have been thoroughly elucidated. These fruitful Results imply that the changes of key molecules in crucial signal pathway will cause severe dysfunction in signal transduction and gene regulation network in polygenic tumors, indicating that in the category of pathogenesis,these tumors may further classify as the "Disease of gene signal transduction and gene regulation network disorder". The researches have laid solid foundation for revealing the molecular mechanism and transcriptomic regulation of polygenic tumors at different stages.
