Objective: To observe the effect of Shenqi compound recipe on glucose and lipid metabolism in patients with Qi and Yin deficiency and blood stasis syndrome newly diagnosed type 2 diabetes mellitus (T2DM), and its intervention effect on intestinal microecology and serum proinflammatory factors. Method: The 106 eligible patients were divided into the observation group (54 cases) and the control group (52 cases) by random number table method. Another 40 healthy volunteers in physical examination center of the hospital during the same period were enrolled as health control group. On the basis of Guidelines for the Prevention and Treatment of Type 2 Diabetes in China(2013 edition), control group was provided lifestyle interventions, such as reasonable diet, weight control, moderate exercise, salt restriction, tobacco control, alcohol restriction and psychological balance. In addition to the therapy of the control group, the observation group was given Shengi compound for oral administration, 2 times/days. Both groups were treated for 8 weeks. The fasting blood glucose (FBG), postprandial 2 h blood glucose (PBG), glycosylated hemoglobin (HbA1c), homeostasis model assessment-insulin resistance index (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) before and after treatment were evaluated. The structure and quantity of intestinal flora before and after treatment were detected. The traditional Chinese medicine(TCM)symptom was scored. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), IL-8, and tumor necrosis factor-α (TNF-α) were measured before and after treatment. Result: FBG, PBG, HbA1c and HOMA-IR levels in observation group were lower than those in control group (PPPPβ, IL-6, IL-8 and TNF-α levels in observation group were lower than those in control group (PZ=2.134, PConclusion: Shenqi compound can regulate blood glucose and blood lipid in patients with newly diagnosed T2DM (Qi and Yin deficiency and blood stasis syndrome), improve IR, intestinal microecology imbalance, and reduce non-specific inflammatory response, with a good clinical efficacy on intestinal microecology of patients with Qi and Yin deficiency and blood stasis syndrome newly diagnosed type 2 diabetes mellitus.

Feasibility of Aortic Dissection Occlusion via Mini-thoracotomy by Trans-esophageal Echocardiography Guidance / 中国循环杂志

Objectives: To explore the feasibility of aortic dissection (AD) occlusion via mini-thoracotomy by trans-esophageal echocardiography (TEE) guidance. Methods: Pre-operative TEE was conducted in 2 AD patients, the findings were compared with trans-thoracic echocardiography (TTE) to confirm the diagnosis with quantitative evaluation in order to accurately guiding the wire and sheath pipe into the rupture crevasse of AD for assessing the position, stability and the effect of closure device on local blood flow. Results: TEE confirmed that 2 patients could be treated by interventional plugging and the crevasses of AD were successfully blocked by TEE guidance. Case 1 had DeBakey II AD, crevasse shunt disappeared upon blocking, false lumen formed thrombosis, the diameter reduced form 40 mm to 28 mm and the cavity was retracted about 40%. Case 2 had the ulcer type AD located in aortic arch, closure device was closely suit to aortic wall, spread well and crevasse shunt disappeared;blood flow in aortic arch was about 110 cm/s which was similar at pre- and post-operation, no vascular stenosis and local dilatation were found, vital sign was stable. Follow-up TTE was performed at 1 month after the operation which showed the position of closure devices were normal in both patients. Conclusions: TEE could effectively confirm pre-operative AD diagnosis and provide intuitive image and quantitative information for accurately guiding closure position and evaluating surgical result. Mini-thoracotomy with TEE guidance is feasible for interventional therapy of AD.

An Interdisciplinary Nutrition Support Team Improves Clinical and Hospitalized Outcomes of Esophageal Cancer Patients with Concurrent Chemoradiotherapy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The prevalence of malnutrition is very high in patients with cancer. The purpose of this study was to investigate whether or not a nutrition support team (NST) could benefit esophageal cancer patients undergoing chemoradiotherapy (CRT).</p><p><b>METHODS</b>Between June 2012 and April 2014, 50 esophageal cancer patients undergoing concurrent CRT were randomly assigned into two groups: The NST group and the control group. The nutritional statuses of 25 patients in the NST group were managed by the NST. The other 25 patients in the control group underwent the supervision of radiotherapy practitioners. At the end of the CRT, nutritional status, the incidence of complications, and completion rate of radiotherapy were evaluated. Besides, the length of hospital stay (LOS) and the in-patient cost were also compared between these two groups.</p><p><b>RESULTS</b>At the completion of CRF, the nutritional status in the NST group were much better than those in the control group, as evidenced by prealbumin (ALB), transferrin, and ALB parameters (P = 0.001, 0.000, and 0.000, respectively). The complication incidences, including bone marrow suppression (20% vs. 48%, P = 0.037) and complications related infections (12% vs. 44%, P = 0.012), in the NST group were lower and significantly different from the control group. In addition, only one patient in the NST group did not complete the planned radiotherapy while 6 patients in the control group had interrupted or delayed radiotherapy (96% vs. 76%, P = 0.103). Furthermore, the average LOS was decreased by 4.5 days (P = 0.001) and in-patient cost was reduced to 1.26 ± 0.75 thousand US dollars person-times (P > 0.05) in the NST group.</p><p><b>CONCLUSIONS</b>A NST could provide positive effects in esophageal cancer patients during concurrent CRT on maintaining their nutrition status and improving the compliance of CRF. Moreover, the NST could be helpful on reducing LOS and in-patient costs.</p>

Development of SYBR Green I real-time RT-PCR for the detection of Ebola virus / 病毒学报

In order to establish a rapid and accurate method for the detection of Ebola virus (EBOV), the primers used in SYBR Green I real-time RT-PCR were designed based on the EBOV NP gene sequences published in GenBank. The SYBR Green I real-time RT-PCR was established and optimized for the detection of EBOV. The EBOV RNA that was transcribed in vitro was used as a template. The sensitivity of this method was found to reach 1.0 x 10(2) copies/microL and the detection range was 10(2) - 10(10). No cross reaction with RNA samples from Marburg virus, Dengue virus, Xinjiang hemorrhagic fever virus, Japanese encephalitis virus, Influenza virus (H1N1 and H3N2) and Porcine reproductive and respiratory syndrome virus E genomic RNA was found. The method would be useful for the detection and monitoring of EBOV in China.

Objective To investigate the dynamics and development trends of drinking water type of endemic fluorosis after water improvement in Xinbaerhuyouqi of Hulunbeir city, Inner Mongolia and to provide a scientific evidence for the development of countermeasures. Methods We mainly selected Adunchulusumu and Kerlunsumu in Xinbaerhuyouqi of Hulunbeir city as the two monitoring points after water improvement in 2000 -2009. Of these, 1 sample of centralized water supply source water and 3 samples of tap water and 5 samples of noncentralized water supply source water according to water well locations of east, west, south, north and center were collected and the levels of water fluoride were tested; the prevalence of dental fluorosis of school children aged 8 to 12 were examined; from 2002 onwards, the urine samples of 30 children aged 8 to 12(five age groups, six urine samples for each age group) were collected, and all urine samples were collected in the case of less than 30, and urine fluoride was tested. Dental fluorosis was diagnosed using Dean method; water fluoride was tested using fluoride ion selective electrode(WS/T 106-1999); urinary fluoride was tested by determination of fluoride in urine using ion-selective electrode(WS/T 89-1996). Results In 2000 - 2009, the mean levels of fluorine in drinking water in Adunchulusumu and Kerlunsumu were 1.79 - 4.35 mg/L and 1.38 - 3.18 mg/L, respectively; the detection rate of dental fluorosis of children aged 8 to 12 were 45.24％(19/42) - 89.78％(123/137) and 40.00％ (28/70) - 74.47％ (70/94), respectively; the median urinary fluoride of them were 2.30 - 4.15 mg/L and 2.73 - 4.55 mg/L, respectively. ConclusionsThe detection rate of children's dental fluorosis remains high in Xinbaerhuyouqi during the past 10 years after changing water. The endemic fluorosis remains a serious disease. Effective prevention and control measures must be taken to control the occurrence of fluorosis in the future.

Influential factors on the effectiveness of 131I treatment on post-surgical differentiated thyroid cancer patients / 中华核医学杂志

Objective To investigate the influential factors on the effectiveness of the first 131I ablation therapy on thyroid remnant and of 131I treatment on metastatic lesions in differentiated thyroid cancer (DTC) patients. Methods Retrospectively,46 DTC cases (divided into complete-ablation group and incomplete-ablation group) of first 131I ablation were enrolled,and 40 DTC cases (divided into remission group and in-remission group) of consecutive 131I treatments on metastatic lesions were enrolled. Influential factors were analyzed (t-test,t'-test,x2-test,Fisher exact test) and logistic regression analysis was performed. Results For the first 131I ablation effectiveness,surgical method,remnant thyroid weight,thyroid stimulating hormone (TSH) level,interval between surgery and 131I ablation therapy,metastatic status were selected as influential factors (x2 = 5. 804,t' = - 5. 258,t' = 7. 376,x2 = 8. 867,x2 = 8. 615,all P ＜0. 05). After logistic regression analysis,formula was obtained as y = 3. 766 - 0. 947x1 ( remnant thyroid weight) -3. 149 x2 (lymph node metastasis) -3. 373 x3 (distant metastasis). For metastatic treatment effectiveness,remission rate of papillary DTC was higher than that of follicular DTC,remission rate of patients with lymph node metastasis was higher than that of distant metastasis,remission rate of total thyroidectomy was higher than that of other types of thyroidectomy ( Fisher exact test,x2 = 7. 278,P ＜ 0. 05 ). In remission group,serum TSH level was much higher and thyroglobulin (Tg) level was much lower before the first ablation therapy (t =4. 489,t' = -4.906,all P ＜0.01 ). After logistic regression analysis,formula was obtained as y = - 0. 363 + 0. 065 x4 ( TSH level) - 0. 250 x5 ( Tg level). Conclusions Influential factors of success rate of the first 131I ablation therapy included surgical method,remnant thyroid weight,TSH level,interval between surgery and 131I ablation therapy and metastatic status,while determinant factors were thyroid remnant weight,lymph node metastatic status and distant metastatic status. The influential factors of success rate of 131I treatment on metastatic lesions included pathological type,surgical method,metastatic status,TSH level and Tg level,while determinant factors were TSH level and Tg level before the first 131I ablation therapy.
