ABSTRACT
This paper aims to study the effect of Xiangqin Jiere Granules(XQ) on lipid metabolism and chronic inflammation in different obesity model mice. The monosodium glutamate(MSG) obese mouse model was established by subcutaneous injection of MSG in newborn mice, and the high fat diet(HFD) obese mouse model was established by feeding adult mice with HFD. The normal mice were assigned into the control group; the MSG obese mice were assigned into MSG model group, XQ4.5 group(Xiangqin Jiere Granu-les, 4.5 g·kg~(-1)), XQ22.5 group(Xiangqin Jiere Granules, 22.5 g·kg~(-1)); the HFD obese mice were assigned into HFD model group, XQ4.5 group, and XQ22.5 group. The mice were intragastrically administrated with saline or XQ for 5 weeks. After that, the body weight, visceral fat mass, liver and thymus weight, and the organ indexes in each group were measured. The levels of triglyceride(TG), total cholesterol(TC), and low-density lipoprotein cholesterol(LDL-c) in serum and liver tissue were detected by the kits. The mRNA expression levels of acetyl CoA carboxylase 1(ACC1), fatty acid synthetase(FAS), diacylgycerol acyltransferase 1(DGAT1) and hepatic lipase(HTGL) involved in lipid metabolism in mouse liver tissue were detected by quantitative real-time PCR(qPCR). The protein levels of tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6) in serum were detected by ELISA, and the mRNA levels of TNF-α and IL-6 in liver tissue were detected by qPCR. Compared with the control group, MSG and HFD mice showed increased body weight, abdominal circumference, Lee index and visceral fat mass as well as elevated levels of TG, TC, and LDL-c in serum. The model mice had up-regulated gene levels of ACC1, FAS and DGAT1 while down-regulated gene level of HTGL in the liver. Furthermore, the mRNA and protein levels of IL-6 increased in the model mice. Compared with the model mice, XQ treatment decreased the body weight, abdominal circumference, Lee index, and visceral fat mass, lowered the levels of TG, TC, and LDL-c in se-rum, down-regulated the gene levels of ACC1, FAS, and DGAT1 in liver tissue, up-regulated the gene level of HTGL, and down-regulated the mRNA and protein levels of IL-6. To sum up, XQ has good therapeutic effect on different obesity model mice. It can improve lipid metabolism and reduce fat accumulation in obese mice by regulating the enzymes involved in lipid metabolism, and alleviate obesity-related chronic low-grade inflammation.

Objective To develop a simple,multi-dimensional self-screening questionnaire for som-atoform symptoms(SQSS). Methods Based on theoretical framework,the study developed the items of the questionnaire. The first draft of the questionnaire was screened through the expert evaluation method. Four groups of 359 subjects were selected to test the reliability and validity of questionnaire. Results The explor-atory factor analysis showed that the four factors(somatic symptoms,negative perception,illness behavior and social function) were extracted and the interpretable percentage of variance was 61. 165%. The correlation between the subscales and the total scales was 0. 740-0. 887,and the correlation coefficient between the sub-scales was 0. 503-0. 625. The Crobanch's α coefficient of the questionnaire was 0. 926,and the Spearman-Brown score of the questionnaire was 0. 868. The retest correlation coefficient of the total scale was 0. 876. A cutoff of 23 points in the SQSS was identified for screening somatoform disorders, and the sensitivity was 0. 880 and the specificity was 0. 606. Conclusion SQSS has good reliability and validity,and can be prelim-inarily used as a self-screening tool for patients with somatoform symptoms or disorders in clinical settings.
ABSTRACT
Objective:To test the psychometric characteristics of the Chinese Version of the Illness Attitudes Scale(IAS-CV).Methods:Totally 297 patients (with somatoform disorders,major depressive disorder,generalized anxiety disorder,panic disorder,and obsessive-compulsive disorder diagnosed with ICD-10) and 212 normal people were assessed with IAS-CV,Beck Depression Inventory-Ⅱ and Beck Anxiety Inventory.Results:The confirmation factor analysis result of the nine-factor model of IAS-CV was x2/df=1.99,GFI =0.86,RMSEA =0.06.The total score of IAS-CV was correlated with BAI scores (r =0.45,P ＜0.01) and BDI-Ⅱ scores(r =0.42,P ＜0.01).Patients with somatoform disorders (62 ± 17) had higher scores than patients with other disorder,such as depression (43 ± 16),anxiety (46 ± 21),obsessive compulsive disorder (46 ± 15),and normal controls (35 ± 13).The Cronbach's α coefficients were 0.91 for IAS-CV and 0.62-0.91 for each subscale.The test-retest coefficients were 0.95 for the total scale and 0.67-0.93 for each subscale (P ＜ 0.01).Split-half coefficient was 0.94.The cut-off score of IAS-CV for screening somatoform disorders was 44.Conclusion:It suggests that the Chinese Version of the Illness Attitudes Scale(IAS-CV) has good psychometric features and could be used in clinical practice and research in China.
ABSTRACT
The paper analyzes the papers of national and provincial Centers for Disease Control and Prevention (CDC) on the Web of ScienceTM from 2007 to 2016 based on h-index,ESI highly cited papers,ESI hot papers and other bibliometrics indexes,contrasts the academic influence of China CDC and five provincial CDCs with top 5 number of SCI papers,and puts forward the suggestions that China CDC should play the role of an academic leader,and the provincial CDCs should continuously give full play to their advantages in their respective research fields.
ABSTRACT
This paper describes the development of the combined tumor therapeutic equipment based on the theory of 1 + 1 = 3 or 1 + 1 > 3 tumor combined treatment synergism. It has become a promising and valuable method dealing with cancer tumors for its good adaptability, better effectiveness and convenience. The therapeutic equipment is combined with PC and MS windows operation system, and adopts intellectual temperature control device, which realizes homogeneous and smooth heating to intracavity tumor focus and automatic processing and statistical management of all case data. The equipment works stably and is of great value in clinical applications.

The development of a RF ablation therapeutic instrument based on improved PID algorithm is introduced here. It is based on the theory of radio frequency local destruction. By adopting the improved PID temperature control algorithm, the problem of the temperature control precision reduction due to tumor tissue characteristic changing by heating has been solved, thus ensuring homogeneous and smooth radio frequency heating to tumor foci. Experiments demonstrate that the new algorithm has strong adaptability and anti-disturbance capability, the equipment works stably and reliably, and can control therapeutic temperature precisely (+/- 2 degrees C), which indicates a good clinical application value.
