1.Analysis on twins recruitment in 6 to 16 years old in Chongqing
Journal of Chongqing Medical University 2007;0(12):-
Objective:This study is to explore available approaches to selling up a twin registry, which was based on their mental development and status of their mental health. Methods:In order to choose suitable approaches to setting up the twin registu, police, education committee-school and newspaper approaches are compared. Two-step-method is adopted to construct the twin registry. The first step is In collect basic data of twins and the second step is to contact children's guardians, get the signatures to the comprehending and consent document from the guardians and then bring the twins into the registry formally. Result:The successful recruit ratios of the police approach, the education commiltee-school approach and the newspaper approach are 4%, 42.6% and 29.2%. The refusing ratios of the education committee-school approach and the newspaper approach are 57.4% and 70.8%. Then we adopted a series of methods to reduce the refusing ratios. The refusing crowds were contacted again. The re-refusing ratio of the education committee-school approach and the newspaper approach are 31.03% and 55.88%. The overall refusing ratio of the education commillee-school approach and the newspaper approach are 17.82% and 39.58%. Conclusions:Every approach has its own advantages and disadvantages. The available approaches should be adopted to setting up the twin registry according to the characteristics of the research.
2.Cardiovascular risk factors in hypertensives complicated with non-alcoholic fatty liver but normal aminotransferase
Chinese Journal of General Practitioners 2011;10(8):552-554
Objective To explore cardiovascular risk factors in patients of hypertension (HTN) complicated with non-alcoholic fatty liver but normal aminotransferase. Methods Forty-four cases (control group) of uncomplicated hypertension and 56 cases (study group) of hypertension complicated with nonalcoholic fatty liver but normal aminotransferase were screened from those who visited physical examination center of the hospital for regular checks-up during October 2009 to June 2010. Blood pressure ( BP), body mass index ( BMI), fasting plasma glucose (FPG), total serum cholesterol (TC) , triglyceride (TG), highdensity lipoprotein-cholesterol ( HDL-C ), low-density lipoprotein-cholesterol ( LDL-C ), gammaglutamyltransferase ( GGT ), uric acid ( UA ) , highly-sensitive C-reactive protein ( hs-CRP) and homocysteine (Hey) of the two groups were compared. Results Comparing with the control group, the study group had higher diastolic blood pressure ( DBP) (t = 1898. 5, P < 0. 05) , BMI (t = - 5. 036, P < 0.01), FPG (t= -2.026, P<0.05), TG (t = 1923. 5, P<0.05), GGT (t = 1789, P <0.01), UA 0 = 1715, P<0.01), hs-CRP (t = 1832.5, P < 0.01) and lower level of HDL-C (t =2357.0, P< 0. 01). Serum activity of GGT correlated positively with BMI (rs = 0. 349, P = 0. 000), TG ( rs = 0.413,P =0.000), UA (rs =0.446, P= 0.000) and hs-CRP (rs =0.350, P = 0.000), respectively.Conclusions When patients of hypertension complicated with non-alcoholic fatty liver but normal aminotransferase, their cardiovascular risk factors clustered further, with serum activity of GGT obviously increased which correlated positively with various risk factors, indicating increase in cardiovascular risks.
3.Application of Serum miRNA-720 and miRNA-484 in the Staging and Early Diagnosis of Colon Cancer
Journal of Modern Laboratory Medicine 2017;32(1):77-79,83
Objective To investigate whether serum miRNA-720 and miRNA-484 can be used as non-invasive biomarkers of colon cancer.Methods Real time-polymerase chain reaction was used to detect the expressions of miRNA-720 and miRNA-484 in serum from 104 colon cancer patients(divided intoⅠ~Ⅱ-stage group andⅢ~Ⅳ-stage group)compared with 60 ad-ditional healthy controls.ROC curve was performed to analyse the diagnostic usefulness of both miRNAs distinguishing be-tween different stages of colon cancer patients.Results Compared with healthy controls,the miRNA-720 was upregulated close to 2 times inⅠ~Ⅱ-stage group (t=1.997,P<0.05),and was upregulated about 3 times inⅢ~Ⅳ-stage group (t=2.133,P<0.05).The miRNA-484 was downregulated almost 2 times inⅠ~Ⅱ-stage group (t=2.585,P<0.05),but was upregulated over 3 times in Ⅲ~Ⅳ-stage group (t=3.416,P<0.01).The area under the ROC curve (AUC)for the diag-nosis of colon cancer were 0.76 (95%CI:0.67~0.86)and 0.79 (95%CI:0.69~0.89)respectively.The combined use of both miRNAs could make the AUC up to 0.87 (95%CI:0.77~0.96).Conclusion Serum miRNA-720 and miRNA-484 can be used as non-invasive biomarkers to diagnose early colon cancer.They can also distinguish between different stages of co-lon cancer patients.
4.Effects of Monosodium Glutamate on Survival and Reproductive Ability of Drosophila melanogaster
Journal of Environment and Health 1992;0(04):-
Objective To study the effects of monosodium glutamate on viability and fertility of filial generation Drosophila.Methods Different concentrations(15,30,45 g/L)of L,H,T monosodium glutamate(MSG)were added in the medium for wildtype Drosophila melanogaster,and the non-MSG medium was taken as the control group,3 pairs of Drosophilas in each bottle and 3 repeats in each group,the first and second filial generation adult Drosophila's eclosion time(growth period) and the number of offspring within 7 days(reproduction quantity),and the death count in 30 days of 20 Drosophilas were observed and recorded.Results Compared with the control group,the reproduction quantity of Drosophila significantly increased,the growth period shortened in the first filial generation in 15 g/L of T MSG group.As the MSG concentrations increased,the reproduction quantity reduced significantly,the survival rate of Drosophila in 30 days declined significantly.The reproduction quantity in second filial generation increased at the initial stage of exposure and then decreased as the MSG concentrations increased.Conclusion The results of the present paper indicates that low-dose of MSG may be the advantage for survival and reproduction of Drosophila,but high doses will produce adverse effects.

9. Establishing the pediatric clinical medicine comprehensive evaluation system: Exploration of the method and path
Journal of International Pharmaceutical Research 2016;43(4):585-590
Due to the weak foundation of clinical trials, the pre-market data of pediatric medicine is insufficient. Therefore, a comprehensive evaluation system of pediatric clinical medicine is urgently needed to safeguard the children’s medication safety. This article provides the method and builds path to establish the comprehensive evaluation system from the aspects of biulding organizational structure, operational process and evaluation methodology, respectively. Further, based on the concept of "Evidence-based or otherwise evidence-created", and following the example of "Mini-Sentinel" of the United States, the big data in medicine can be used to overcome the "Evidence-created" difficulty in the evaluation of pediatric medication. Thus more extensive comprehensive evaluation can be made through collecting the clinical data generated from the real world for the pediatric medication. In the future, the comprehensive evaluation system of pediatric clinical medicine established on the basis of big data can be linked to the "Precision Medicine" Project in our country, the evaluation bases can be the "Mini-Sentinel" to collect big medical data and biological samples, thus to bring a steady flow of power for promoting the pediatric medicine active surveillance and pediatric precision medicine, and finally to safeguard the children’s health in our country.
10.Biological treatment for intervertebral disc degeneration.
China Journal of Orthopaedics and Traumatology 2016;29(6):576-580
Neck shoulder pain or lumbocrural pain caused by intervertebral disc degeneration (IDD) could seriously affect the qualities life of patients. Current treatments mainly focus on alleviating pain and the symptoms of nerve compression, which could not radically stop the process of intervertebral disc degeneration, but conversely lead to high recurrence rate. In recent years, scholars have turned to study the biological treatment for repair and rebuild the intervertebral disc by biological molecular therapy, gene therapy, cell therapy and tissue engineering to solve the problem of intervertebral disc degeneration, while most of the above methods are still in animal experiments or in vitro experiments and the clinical application is still a long way to go.
