Estrogen has many physiological functions. It can prevent atherosclerosis, coronary heart disease and osteoporosis etc. Phytoestrogen is a kind of natural compounds in plants that is structurally similar to estrogen and has estrogen-like effects. The studies on the effects of estrogen and phytoestrogen on the hypoxia at present is limited and its mechanism is being researched.

ObjectiveTo investigate the diagnosis and treatment of gastric paralysis after gastric operation.MethodsThe clinical data of 21 patients with gastric paralysis after gastric operation were reviewed retrospectively.Results3.9% of patients occurred gastric paralysis in this group. The diagnosis was depended on patient's symptoms, X-ray graph of the upper digestive tract and gastroscopy. The patients were healed after conservative treatment.ConclusionThe combined conservative treatment is the ideal method to treat the gastric paralysis syndrome.

Gentisate (2,5 dihydroxybenzoate) pathway is one of three typical routes for bacterial aromatic catabolism Although it is less common than either of the extensively studied pathways through catechols, the gentisate pathway also plays an important role in bacterial aromatic catabolism This article reviews recent developments of this pathway, both in biochemistry and molecular biology

This paper reported all kinds of assay of soybean isoflavone on the basis of collecting and analyzing relating literatures at home and abroad. The assay conditions were listed and compared in this paper. The authors believed that the assay should be selected according to the circumstances.

Objective:To investigate ?-catenin expression during check pouch carcinogenesis in golden hamster.Methods:Expression of ?-catenin was examined with immunohistochemical SABC method in 23 cases of check normal buccal epithelium of golden hamster,22 of hyperplasitic epithelium,22 of dysplastic epithelium,29 of squamous cell carcinoma.Results:Normal buccal epithelium showed strong pericellular staining in the basal,suprabasal and prickle cell layers.Positive rates(%) of ?-catenin in normal buccal epithelium,hyperplastic epithelium,dysplastic epithelium and squamous cell carcinoma were 100,100,77.3 and 41.4 respectively.Conclusion: The decreased expression of ?-catenin may be related to the carcinogenesis of golden hamster check pouch.

OBJECTIVE: To explore the diagnostic value of the proposed thyroid imaging reporting and data system (TI-RADS) classification in thyroid nodules, and to investigate interobserver variability among different observers using TI-RADS classification for ultrasound. METHOD: We reviewed 667 thyroid nodules conventional ultrasound image data from 532 patients who were confirmed by Pathological diagnosis. Those ultrasound images were reviewed by 4 experienced sonographers who can independently assessed the sonographic characteristics and analyzed according to the TI-RADS classification. It is to assess the diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the TI-RADS classification. The multirater kappa statistics were used to assess the interobserver agreement among different observers. RESULT: The overall sensitivity, specificity, negative predictive value (NPV) and Accuracy were 94%, 79%, 97% and 81%, respectively. Positive predictive values (PPVs) for categories 4 and 5 were 55% and 92%. There was substantial interobserver agreement for categories 3, 4B and 5 (Kappa = 0.62, 95% CI, 0.58-0.65), and was moderate agreement for category 4A (Kappa = 0.57) and 4B(Kappa = 0.60). CONCLUSION The diagnostic criteria of TI-RADS for differentiating between benign and malignant thyroid nodules have a high diagnostic value. There was substantial interobserver agreement in different experienced sonographers. The TI-RADS diagnostic criteria have a high diagnostic value and has great practical value in making a proper and further treatment plan.

Objective To study the characteristic of operation design and analyze curative effect of laser sub-epithelial keratomileusis (LASEK) on low and midrange myopia in aged patients. Method Fiftyeight patients ( 114 eyes) no less than 35 years old were treated with LASEK by monoblepsis. The subjects were examined and analyzed at 3 days, 7 days, 1 month,3 months and 6 months after operation. Results Seventy-one corneas(62.28%) recovered well at 3 days after operation. At 1 month after operation, the acuity of vision of all patients achieved or exceeded corrected vision before operation,and lasted to 6 months after operation. The break up time of 63 eyes were lower than normal at 3 months after operation,but 6 months after operation all of them recovered to normal. The satisfaction of patients raised gradually. Conclusions LASEK is effective for no less than 35 years old myopic patients. Make operation plan refer to monoblepsis and patients' needs can receive more satisfaction.

Objective To know the effect of using clustering intervention on insulin injection in the patients with type 2 diabetes.Methods 123 patients with type 2 diabetes were selected in the research.Clustering intervention was carried out in these patients with a series of effective measures to develop and integrate the application.Compared the controlling condition of blood sugar and the condition of insulin injection in patients by self control.Results The fasting blood glucose and the postprandial blood glucose after the intervention was (5.91±0.41) mmol/L and (8.27±0.53)mmol/L respectively,which was significant lower than that of before the intervention [(8.94±1.32) mmol/L and (11.15±1.34)mmol/L respectively,P＜0.01].Conclusion Clustering intervention can regulate insulin injections,improve patients' ability of self-management and the treatment compliance,effectively control blood sugar and delay or reduce complications after the implementation of cluster intervention.

Chemotherapy is one of the primary treatment for malignant tumors.Platinum drugs as the most commonly used cycle non-specific clinical antitumor drugs show good curative effect in the clinical treatment of solid tumors,however,resistance or cross-resistance of theplatinum analogous has become one of the main obstacles for platinum and its analogous,which limits their clinical applications.miRNAs play an important role in biology,including cell proliferation,differentiation,apoptosis,stress tolerance,and physiological metabolism.There is a close relationship between miRNAs target gene regulation and tumor drug-resistance.This article is mainly about the role of miRNAs in tumor of platinum resistance.

Objective To explore the necessity and effect of the motivational interviewing/MIcurriculum in medical school students. Methods Helping smoking cessation in standard patients with coronary heart disease was assumed as the expected goal. MI was carried out for medical school students to master basal knowledge and skills of MI and help using MI methods in persuading smoking quitting. The teaching mode of MI curriculum was comprised of a lecture series and small group dis-cussion with videotaped practice in role plays. Motivational Interviewing Treatment Integrity (MITI) scoring tool was applied to assess the teaching effect of MI curriculum with students' performance videotapes. Questionnaire was used to evaluate the quality and efficacy of the MI curriculum, and SPSS 13.0 was used to t test measurement data. Results Analysis of the MITI scores showed students had general mastery of MI knowledge. Nevertheless, they did not reach recommended professional profi-ciency level. The scores of empathy and MI spirit in global ratings were (4.11 ±0.32) and (5.82 ± 0.17), respectively (recommended level, 6 score). In the videotape evaluation of behavior counts, MI adherentreached (70.96%±24.34%) (recommended level, 90%). Open question reached (31.42%±8.51%) (recommended level, 70%). Total refection counts were (7.84±3.22) counts per video (recom-mended level, 10). The standard questions recommended in MI for behavior change were better used by students. 93.75%and 87.50%students used ranking questions to evaluate the importance and con-fidence of smoking quitting. Nevertheless, the exploration questions about importance and confidence were less used to know the reason behind their ranking . The results of questionnaire showed that 83.33%students felt MI curriculum effective to help them improve confidence and skills in counseling with patients. 97.91%students thought the mastery of MI methods as an important skill for physicians to have. Conclusion The teaching practice of MI curriculum in medical school students is necessary and feasible with good teaching results. It is worth for professional counseling regarding unhealthy be-havior change in patients.
