Objective: To compare the calibration result of standard X-ray RQR radiation field between SSDL (NIRP) and CEA LIST LNHB(France), and to explore the feasibility of calibrating H_p(3) in standard X-ray RQR radiation field of SSDL(NIRP). Methods: Using a column model with a diameter and high of 20 cm, TLD was calibrated in SSDL (NIRP) and CEA LIST LNHB (France) to measure the personal dose equivalent eye lens dose H_p(3), X-ray RQR radiation field included RQR4(60 kV), RQR7(90 kV), RQR9(120 kV), with energy response, angle response and linear response. Results: In terms of energy response, the calibration results of TLD in both SSDL (NIRP) and CEA LIST LNHB (France) were in good agreement. The difference between exposure value and response value was less than 10%. In terms of angle response, the calibration result of TLD in CEA LIST LNHB (France) was better in SSDL(NIRP). The difference between exposure value and response value in CEA LIST LNHB (France) was less than 6%, while the difference between exposure value and response value in SSDL(NIRP) was more than 10% at angle of 20°. In terms of linear response, both calibration result of SSDL (NIRP) and CEA LIST LNHB (France) were in good agreement. Conclusions The standard X-ray RQR field in SSDL (NIRP) can be used for the calibration of H_p(3).

Objective To observe the influence of Buyang Huanwu Decoction ( BYHWD) on the inhibition of rat myocardial H9C2 cell activity and SH2-containing tyrosine phosphatase-1 ( SHP-1) activity induced by trastuzumab, and to explore the possible regulatory mechanism after observing the intervention of BYHWD on rat myocardial H9C2 cell transfected with SHP-1 or SHPC/S-1 gene. Methods The eukaryotic expression vectors pcDNA3.1 (+)- SHP-1 and pcDNA3.1 (+) -SHPC/S–1 were constructed and then were transfected to rat myocardial H9C2 cells using the method of liposome transfection. The cells with positive clones were screened out with G418, and then were cultured with trastuzumab for maintaining growth. Using quantitative RT-PCR, we detected the expression of SHP-1 gene and SHPC/S - 1 gene in rat myocardial H9C2 cells. The phosphatase activity analysis was used for observing the regulatory effect of BYHWD on SHP-1 in myocardial cells. Furthermore, we observed the apoptosis of rat myocardial H9C2 cells by methyl thiazolyl tetrazolium (MTT) assay after treatment with BYHWD. Results Sequencing results indicated the successful construction of eukaryotic expression vectors, which had stable expression in myocardial H9C2 cells even under the intervention of trastuzumab. The results of phosphatase analysis showed that H9C2-SHP-1 had the highest activities of phosphatase, but the activities were decreased after the intervention with BYHWD ( P<0.05) . The results of MTT assay also showed the apoptotic rate of H9C2-SHP-1 cells was decreased after treatment with BYHWD ( P <0.05) . Conclusion BYHWD can promote the proliferation of myocardial H9C2 cells inhibited by trastuzumab, and can regulate the expression of SHP-1 in myocardial cells, which will supply reference to the further study of treatment of trastuzumab-induced cardiac toxicity.

ABSTRACTOBJECTIVE To observe the preventive effect of oxaliplatin induced peripheral neuropathy treated by fumigation of Siteng Yixian decoction.METHODS Totally 150 colorectal cancer patients from oncology department Of Hainan provincial hospital of TCM between January 2010 and December 2014 were enrolled in this study.And they were randomized into two groupswith 75 cases in each.The patients in the control group only received oxaliplatin based chemotherapy.While the pa-tients in the treatment group were given the chemotherapy combined with fumigation of Siteng Yixian decoction.The fumiga-tion lasted for forty minutes a timetwice a day.After the treatment of two cycles chemotherapythe incidence rate and sever-ity classification of peripheral neuropathy was analyzed one month later to evaluate the preventive effect.RESULTS The difference of incidence rate of peripheral neuropathy was significantwith the rate being 18.7% in the treatment group and 56. 0% in the control groupP <0.01.The severity classification was evidently higher in the control group90.37than those in the treatment group60.63and there exised a statistical significanceP <0.05.Among the patients who had second degree peripheral neuropathy or abovethe oxaliplatin accumulative dose was1 054.76±124.6in the treatment group and823.47 ±190.67 in the control groupand the difference was statistically significantP <0.05.Logistic regression indicated that fu-migation of Siteng Yixian decoction was the protective factor for the oxaliplatin?induced peripheral neuropathy.CONCLUSION Fumigation of Siteng Yixian decoction can reduce the incidence ratedecline the severity classification of oxaliplatin?induced peripheral neuropathy and increase the oxaliplatin tolerance dose.It is the independent preventive factor for oxaliplatin?induced peripheral neuropathy.

Objective To investigate the clinical significance of IL-27 in hepatocellular carcinoma ( HCC) in the early stage , and to compare it with alpha-fetoprotein ( AFP) in diagnostic performance .Methods Enzyme-linked immunosorbent assay was used to detect the serum level of IL-27 in the HCC group and control group .Receiver operator characteristic ( ROC) curve was used to ana-lyze two indicators and the logistic regression model predicted value ( PRE) was obtained .Results The study indicated the concentra-tion of IL-27 in HCC group [(364.19 ±177.55)pg/ml] was significantly higher than the control group [(255.49 ±94.33)pg/ml], the area under the curve (AUC) of IL-27 and AFP were (0.804) and (0.818), respectively.Logistic regression obtained the regres-sion model PRE that contains AFP and IL-27, with a predicted area under the ROC curve for HCC (0.901), while the diagnostic sen-sitivity (84.8%) and specificity (96.7%) were significantly higher than the capability of individual diagnosis of each indicator .Con-clusions In this study we obtained the model which can be used for clinical diagnosis of hepatocellular carcinoma in future .

Portal hypertension, as one of the major complications of liver cirrhosis, is a common clinical syndrome characterized by an increased portal pressure and the formation of portal-systemic collaterals. Currently no ideal therapeutic agent has been available for portal hypertension. Sorafenib is an oral tyrosine kinase inhibitor that has been shown to significantly improve blood flow dynamics, inhibit angiogenesis, reduce liver fibrosis and decrease portal pressure in the treatment of portal hypertension. The authors review the progress in the research of sorafenib in the treatment of portal hypertension and the mechanisms of its actions.

We report a case of multiple endocrine neoplasia (MEN) type 2A and summarize the clinical characteristics, diagnosis and treatment of this condition. The diagnosis of MEN type 2A relies on a comprehensive evaluation of the findings of ultrasound, CT and laboratory examinations, and early diagnosis and treatment is critical to improving the prognosis. Genetic testing of RET is the gold standard for diagnosis of MEN type 2A and 2B. Surgical intervention currently remains the primary choice of treatments of this disease.
