Objective To analyze the efficacy and safety of transarterial chemoembolization (TACE) with chemotherapy regimen containing platinum in the treatment of primary liver cancer. Methods 86 patients with advanced hepatocellular carcinoma treated in our hospital from December 2015 to December 2016 were selected and randomly divided into two groups with 43 cases each group. Lipiodol chemotherapy was performed with Lobaplatin, epirubicin hydrochloride and mitomycin in the study group, control group while Lipiodol chemotherapy was performed with oxaliplatin, epirubicin hydrochloride and mitomycin in the control group. The gelatin sponge was used to block tumor blood vessels and the treatment lasted for 2 courses. According to the curative effect evaluation standard of solid tumor (RECIST), the curative effect was evaluated and the adverse reactions were compared between the two groups. Results The total effective rates of the two groups were not significantly different , but the effective rate of the study group (20.93%) was significantly higher than that of the control group (6.98%), and the difference was statistically significant (P<0.05). The incidence of hematologic toxicity in the study group (30.23%) was slightly higher than that in the control group (20.93%), the incidence of gastrointestinal reactions (44.19%) and liver and kidney damage (13.95%) were lower than that of the control group respectively by 60.47% and 25.58%, but there was no significant difference . The incidence of neurotoxicity in the study group (2.33%) was significantly lower than that in the control group (27.91%), and the difference was statistically significant (P<0.05). Conclusion For patients with advanced hepatocellular carcinoma, there was no significant difference between the efficacy and safety of transarterial chemoembolization with chemotherapy regimen containing platinum and oxaliplatin chemotherapy regimen, and adverse reactions are similar, but the incidence of neurotoxicity is low.

OBJECTIVETo obtain the Escherichia coli strains expressing N-Acetyl-D-neuraminic acid aldolase (Neu5Ac aldolase).

METHODSThe gene (nanA) coding Neu5Ac aldolase was cloned from Escherichia coli C600, and the recombinant plasmid was sequenced and expressed in Escherichia coli.

RESULTSSequencing data revealed that the open reading frame was 894 bp and predicted to encode a protein consisting of 298 amino acids. The patterns of SDS-PAGE showed that the purified enzyme protein as a single protein band with a molecular weight of 33 kD, which was consistent with those reported in the reference. In the recombinant plasmid pRY1, the expression of nanA gene was controlled by the lac promoter with the induction of IPTG or lactose. The plasmid pRY3 was constructed, in which the nanA gene ws controlled by the tac promoter. The protein of Neu5Ac aldolase was constitutively expressed using the recombinant strain, E.coli DH5 alpha/pRY3 without induction of IPTG or lactose. The crystal was finally obtained with the efficiency of 90.2% of Neu5Ac. The HPLC indicated that the Neu5Ac crystal prepared in this experiment was same as Simga product.

CONCLUSIONThe protein products expressed by two recombinant strains E.coli BL21(DE3)/pRY1 and DH5 alpha/pRY3 has the characteristics of Neu5Ac.

Objective To improve the precision of the traditional segmentation of echocardiogram, by suppressing the influence from inherent speckle noises in medical ultrasonic images. Method An automatic segmentation method based on reconstructed morphology was proposed in this paper. First, the opening and closing operations by reconstruction were imposed to the ultrasonic image. Second, the top-hat operation was used to extract the bright and/or dark features and to find out the boundaries corresponding to these features, whereby implemented the automatic segmentation. Result The segmented echocardiogram had less artificial boundaries resulted from speckle noise, and could accurately be extracted the artery and ventricle. Conclusion The presented method can detect both dark and bright objects accurately, and the boundary has a fine continuity. In addition, the algorithm is also applicable to the extraction of sole bright/dark features, accordingly to reduce the complexity and time needed and to improve the accuracy.

Objective To study the mental health condition of occupational female and influencing factors of mental health. Methods 827 occupational females in Dongguan city were investigated using the questionnaires, the contents included the basic personal information, mental health condition and influencing factors of mental health.Results The results showed that there existed higher ratio of mental disorder in people of age over 50 years, post-graduate educational background, monthly income levels of 4001 to 5000 yuan and divorced occupational females.Moreover, the influential factors on mental health of occupational females were correlated with age, culture degree,family population and society. Conclusion We should pay more attention to occupational females and take effective measure to relieve their mental stress. This is the demands of woman as well as society.

Objective To evaluate and compare the diagnosis and treatment quality of 15 tertiary hospitals in Beijing with the quality-evaluation model of STEMI.Methods The quality-evaluation model has been formatted with the document analysis method and expert consultation method,with the indicators weighted by analytic hierarchy process.By collecting the data of 15 hospitals,we can get the values of indicators,then synthetically evaluate and compare the diagnosis and treatment quality at these 15 hospitals with the method of WRSR.Results In the diagnosing and treating the cases of STEMI at the hospitals,gaps are found between the clinical guidelines and the tests,patient evaluation,reperfusion treatment and drug therapy,with some indicators falling even below 22％.Also,there are significant differences in the diagnosis and treatment quality among hospitals.All hospitals are consistent on the five dimensions-tests,patient evaluation,reperfusion treatment,drug therapy and prognosis.Conclusion The quality-evaluation model of STEMI can comprehensively reflect the diagnosis and treatment quality of cardiovascular medicine,and partly reflect hospital's overall management level,so as to provide operating methods in improving hospital diagnosis and treatment quality.

Objective To compare the clinical evaluation in diagnosis of thyroid nodules between fine needle aspiration(FNA) and core needle biopsy(CNB).Methods 82 cases with thyroid nodules undergoing FNA and 33 cases with thyroid nodules undergoing CNB were selected.Cytology,histopathology,and postoperative results were compared with postoperative pathology as the gold standard.Results The accuracy,sensitivity,specificity,positive predictive value,negative predictive value,false positive rate,false negative rate of FNA and CNB were 91.5％ vs 87.9％,93.2％ vs 87.5％,87.0％ vs 88.9％,94.8％ vs 95.5％,83.3％ vs 72.7％,13.0％ vs 11.1％,6.8％ vs 12.5％,respectively.There was no significant difference between FNA and CNB (P＞0.05).Conclusion Both of FNA and CNB examination show high accuracy,sensitivity and specificity in diagnosis of benign and malignant thyroid nodules,but FNA is more economical,safe,convenient and thus has more extensive clinical application.For lymphoma or borderline tumor,CNB examination combined with immunohistochemistry is of more advantages.
