4-(Cytidine-5-diphospho) -2-C-methyl-D-erythritol kinase is a key enzyme in the biosynthesis pathway of terpenoids. According to the transcriptome database, the specific primers were designed and used in PCR. The bioinformatic analysis of the sequenced TwCMK gene was performed in several bioinformatics software. The Real-time fluorescence quantification polymerase chain reaction (RT-qPCR) were used to detect the expression levels of TwCMK from T. wilfordii after elicitor MeJA supplied. The results showed that the full length of TwCMK cDNA was 1 732 bp encoding 387 amino acids. The theoretical isoelectric point of the putative TwCMK protein was 5.79 and the molecular weight was about 42.85 kDa. MeJA stimulated the rising of TwCMK expression in suspension cell and signally impacted at 24 h. The research provides a basis for further study on the regulation of terpenoid secondary metabolism and biological synthesis.

Objective To evaluate risk and the direct economic burden of malignant tumor due to type 2 diabetes mellitus. Methods Combing the data of chronic disease surveillance, follow-up and the fifth health service investigation, we calculated the population attributable risk and the direct economic burden for malignant tumor due to type 2 diabetes mellitus in order to estimate the direct economic burden for tumor caused by type 2 diabetes mellitus. Results The relative risk was 1.68 (95%CI: 1.68-1.70) for people with type 2 diabetes mellitus to develop the malignant tumor than the people without type 2 diabetes mellitus. The proportions of attributable risk (AR%) and population attributable risk (PAR%) were 40.57% and 2.05%, respectively. Moreover, the annual average hospitalization costs for malignant tumor reached 11 billion CNY, which took part 6.48% of total health service costs. And the direct economic burden for malignant tumor due to type 2 diabetes mellitus was 0.228 billion CNY. In addition, the top two highest population attributable risks were colorectal cancer and liver cancer, while the top three greatest direct economic burdens for malignant tumor or malignant tumor due to type 2 diabetes mellitus were lung cancer, colorectal cancer and stomach cancer. Conclusion From this study, we found that type 2 diabetes mellitus increased the risks of tumor and therefore lead to sharply increasing in medical costs of malignant tumor. In order to decrease the risk of malignant tumor and medical costs, we should pay more attention to the prevention of type 2 diabetes mellitus and the screening of malignant tumor due to type 2 diabetes mellitus.

Abstract: Objective To develop a real-time fluorescent quantitative RT-PCR (qRT-PCR) method for qualitative and quantitative Chikungunya virus (CHIKV) analysis. Methods Based on the systematic analysis of the genomic sequences of Chikungunya and its related arboviruses, the specific nucleic acid sequences for Chikungunya virus were screened and identified, and then the primers and TaqMan probe were designed. Meanwhile, the human GAPDH gene was used as an internal reference. The reaction system for qRT-PCR was systematically optimized by L9(34) orthogonal design, and a rapid detection method for Chikungunya by qRT-PCR based on TaqMan probe methods was established. The sensitivity, specificity, reproducibility, and coverage of the established method were analyzed in detail. The standard curve was made, and the absolute quantitative method was established using the cloned nucleic acid fragments as positive samples. Results A real-time fluorescent quantitative RT-PCR assay was developed for the qualitative and quantitative analysis of Chikungunya virus. The reaction system included Chikungunya virus and reference internal gene specific primers and probe, RT/Taq enzyme mixture, reaction buffer, and negative and positive reference. The established method obtained positive results with the ROSS strain of ECSA subtype, LR2006 strain of IOL branch, 181/25 strain of Asian type and Dongguan 2010 epidemic strains of Chikungunya virus, but there was no cross-reaction with other 18 arboviruses belonging to Flaviviruses, Alphaviruses and Bunyavirus. The minimum detection limit of the established method was 5.80 copies/mL, and a linear relationship was observed between the amount of input plasmid DNA and fluorescence signal value over a range of 5.80×102 copies/mL to 5.80×1010 copies/mL, and the correlation coefficient was 0.999 5. The qRT-PCR amplification efficiency was 91%, and the intra-assay variations and inter-assay variations were 0.01-0.07 and 0.03-0.11, respectively. Conclusions The TaqMan qRT-PCR method developed in this study can qualitatively and quantitatively detect Chikungunya virus rapidly with specificity and sensitivity, providing a technical method for the prevention and control of this viral disease.

OBJECTIVEWe observed the therapeutic effectiveness and safety of different antidepressants as well as the correlation between symptomatic improvement of depression and improvement of chest pain in patients with susceptible "angina pectoris" and negative coronary angiogram complicating comorbid depression.
METHODSIn this double-blinded randomized study, a total of 123 eligible patients were allocated into three groups: (1) Group F: fluoxetine 20 mg QN (n = 41); (2) Group P: Placebo 1 tablet QN (n = 40); (3) Group F + O: fluoxetine 20 mg + olanzapine 2.5 mg QN for the former 2 weeks and only fluoxetine 20 mg QN for the latter 2 weeks (n = 42). The total therapy duration was 4 weeks. HAMD, HAMA and self-evaluation table of chest pain were obtained before therapy, at the end of 1 and 2 weeks after therapy.
RESULTSBaseline HAMD and HAMA scores and self-evaluation score of chest pain were similar among 3 groups and all scores were significantly improved post various therapies in the order of group F + O > group F > group P. The rate of score decrease were seen after 1 week treatment in group F + O and after 2 week treatment in group F. There was a significant positive correlation between the rates of self-evaluation chest pain score decrease and HAMD (r = 0.867, P < 0.001) and HAMA (r = 0.854, P < 0.001) score decreases after 4 weeks therapies (P < 0.05). During the whole course of treatment, no serious adverse reaction was found in all patients.
CONCLUSIONIn patients with suspected "angina pectoris" and negative coronary angiogram complicating comorbid depression, the antidepressants were safe and significantly improved the symptoms of depression and anxiety and chest pain. Low dose fluoxetine plus short term olanzapine regimen was superior to fluoxetine alone regimen in terms of stronger and quicker symptom improvement.

A multiplex RT-PCR assay based on GeXP system was developed in order to detect simultaneously human enterovirus 71 (EV71) and coxsackievirus A16 (CVA16) and other coxsackieviruses (CVA4, 5, 9 and 10, CVB1, 3 and 5). Enterovirus detection was performed with a mixture of 12 pairs of oligonucleotide primers including one pair of published primers for amplifying all known pan-enterovirus genomes and eleven primer pairs specific for detection of the VP1 genes of EV71, C A16, CVA4, CVA5, CVA9, CVA10, CVB1, CVB3 and CVB5, respectively. The specificity of multiplex RT-PCR system was examined using enterovirus cell cultures and positive strains identified previously from hand-foot-and-mouth disease (HFMD) patients. Serial dilution of titrated EV71 and C A16 cell cultures and in vitro transcripted RNA of enterovirus VP1 regions were used to detect the sensitivity of the multiplex RT-PCR system. The limit of detection for this multiplex RT-PCR system was 10(0.5) TCID50/microL for EV71 and C A16 cell cultures and 1000 copies for in vitro transcripted RNA of nine viruses per assay. This multiplex RT-PCR assay is a rapid, sensitive and specific assay for the diagnosis of common enterovirus infection in cases of HFMD outbreak and is also potentially useful for molecular epidemiological investigation.
