Objective To observe the clinical effects of modified Shengxian decoction in the treatment of thyroid cancer postoperative hypothyroidism patients.Methods 60 patients of thyroid cancer postoperative hypothyroidism due to deficiency of spleen and kidney were randomly divided into a control group and a treatment group.The control group (28 cases) was by levothyroxine sodium tablets conventional treatment,while the treatment group (32 cases) was treated with Shengxian decoction based on thecontrol group.The changes of the symptom integral and HAMD-17 were observed between two groups before and after treatment.Results After treatment,the total effective rate was 87.5％ in the treatment group and 64.3％ in the control group,the clinical effect of treatment group was significantly better than the control group (x2=4.499,P＜ 0.05).After treatment,the total score of HAMD-17 was 6.8±2.3 in the treatment group and 15.8±2.1 in the control group,both significantly improved than that before the treatment (which were 19.4±1.45 and 18.9± 1.32 respectively).Compared with the control group,the treatment group improved significantly (P＜ 0.01).Conclusion Shengxian decoction plus western medicine has remarkable curative effect in the treatment of thyroid cancer postoperative hypothyroidism,it can improve the depressive state of patients and improve the quality of life.

Objective To analyze the prognostic factors in patients with initially diagnosed bone-only metastatic nasopharyngeal carcinoma (NPC). Methods We collected the data of 68 patients with initially diagnosed bone-only metastatic NPC admitted to The Affiliated Tumor Hospital of Shantou University Medical College from 1997 to 2015. Forty-nine patients received chemoradiotherapy. The Kaplan-Meier method was used to calculate the overall survival rate;the log-rank test was used for univariate prognostic analysis;the Cox model was used for multivariate prognostic analysis. Results The median follow-up was 953 months. The 1-, 2-, 3-, and 5-year overall survival ( OS) rates were 53%, 38%, 21%, and 15%, respectively. The median OS time was 134 months. The univariate prognostic analysis showed that spinal metastases, the number of bone metastases, lactic dehydrogenase level before treatment, the radiotherapy technology and dose for primary tumor, and the short-term outcome of primary tumor were associated with OS ( P=002, 001, 000, 002, 002, 001 ) . The multivariate prognostic analysis showed that ≤3 bone metastases, dose to primary tumor>65 Gy, and intensity-modulated radiotherapy ( IMRT) were favorable prognostic factors for OS ( P=003,002,004) . Conclusions For patients with initially diagnosed bone-only metastatic NPC, active treatment ( IMRT, dose to primary tumor>65 Gy) should be considered for those with ≤3 bone metastases to achieve a complete response of primary tumor.

OBJECTIVETo study the distribution of poly(ADP-ribose) polymerase(PARP) pseudogene polymorphism and the association with susceptibility to lung cancer in Chinese people.

METHODSThe subjects of this study included 63 patients with lung cancer and 82 healthy controls matched in gender and age. Genome DNA was extracted from white blood cells. Products from PCR with a pair of specific primer were electrophoresized in agarose including EB. Under ultraviolet, observation and imaging were performed.

RESULTSThere was no significant difference in genotype between the cases and controls. The frequencies of B allele in cases and controls were 0.095 and 0.116 respectively. Whether there was B allele or not, smoking was a risk factor of lung cancer (P<0.05). As the genotype was AA and AB or BB, smoking OR was 2.28 and 4.83 respectively. Among non-smokers, the risk at lung cancer did not increase in AB or BB genotypes(P=0.202).

CONCLUSIONFrequency of B allele is relatively lower in Chinese people than in other races. In smokers, B allele may be a susceptible marker of lung cancer, and there is synergistic function between B allele and smoking.

Japan is one of the main trading partners for the import and export of experimental animals in China,and its quarantine and supervision policies for the import and export of experimental animals are very detailed and strict.This article takes experimental dogs,cats,and monkeys as examples to provide an in-depth analysis of the quarantine and supervision policies for the main experimental animals exported to Japan.At the same time,it reflects on the current laws and regulations,import and export management method,standards,biosafety,breeding and management status,as well as the import and export business status of experimental animals in China.Suggestions are provided in improving the laws and regulations,import and export management method,ensuring national biosafety,improving the management level of experimental animal breeding,and promoting the import and export trade of experimental animals,in order to provide reference for comprehensively improving the production,use,and breeding management level of experimental animals in China and strengthening the trade between China and Japan.
