Type 2 diabetes mellitus is a metabolic disorder characterized by hyperglycemia caused by multifactors.The incidence of type 2 diabetes is gradually increased.Its prevention and treatment are paid more and more attention.Intestinal flora is one of the hot spots in recent years.A large number of studies have shown that intestinal flora is closely related to the occurrence and treatment of type 2 diabetes mellitus.Intestinal flora is expected to be a new direction for the improvement and treatment of type 2 diabetes mellitus.In this paper,the relationship between type 2 diabetes and intestinal microflora in recent years,pathogenesis and treatment were summarized.

In medical education,the application of discussion of teaching reform can enhance medical students'interest in learning,stimulate their innovative thinking,develop their clinical thinking and critical thinking.improve their psychological quality and language skills and improve knowledge and comprehensive quality of teachers as well.

Objective To evaluate the role of breast MRI in detecting the primary malignancy in patients presenting solely with axillary lymph node metastases. Methods Thirty-three patients with axillary lynph node metastases but negative findings on either physical examination or mammography underwent breast MRI to identify occult breast carcinoma. MRI of the breast was assessed according to BI-RADS criteria. The pathologic diagnosis was made according to the standard criteria by the WHO Classification of Tumor. Results Among 33 patients presenting solely with axillary metastases, 30 patients underwent modified radical mastectomy. Primary breast carcinoma was proven in 17 patients. MRI detected lesions in 16 patients, including 10 masses and 6 non-mass lesions. Size of the masses ranged from 0. 5 to 2. 6 cm (mean 1.5 cm). Six lesions were smaller than 1.5 cm in size. Non-mass lesions showed ductal enhancement in 4 cases and segmental enhancement in 2 cases. One patient with tumor detected by histopathology showed no abnormal enhancement on MRI. No tumor was found at mastectomy in the other 13 womeu, and negative MR findings were revealed in 9. Four cases with suspicious enhancement on MRI had no corresponding primary foci on pathology. Three patients didn't undergo surgical procedure. The sensitivity, specificity, and accuracy of MRI in the diagnosis of the primary malignancy were 94. 1%,69. 2%, and 83.3%, respectively. Conclusions Small size of mass and ductal or segmental enhancement of non-mass lesion were common MR features of occult malignancy. MRI showed high sensitivity and accuracy in diagnosing occult breast carcinoma. Breast MRI should be taken in search of occult malignancy in patients with axillary metastases.

Objective To identify the characteristics oral fungus in HIV-infected patients with HAART in Kunming.Methods Oral mucosal swab samples were collected from 99 patients with HIV infection with or without HAART.The fungi were isolated and cultured,and were identified by using API 20 C AUX yeast identification system.Results The positive rate of oral Candida in was significantly higher in HIV-infected patients without HAART (53.3％) than those with HAART (20.4％) (x2=11.669,P＜0.01).In 41 strains of isolated candida,C.albicans was the most prevalent (78.0％),followed by C parapsilosis (9.8％),C.glabrata (9.8％) and C tropicalis (2.4％).Conclusions HAART can decrease the positive rate of oral Candida in patients with HIV infection,but has little effect on asymptomatic HIV carrier.

Wearable technology, widely applied in health and medical field, has become an important part of in-telligent healthcare and medicare. However, the data security and privacy protection of wearable health and medi-cal devices are greatly concerned and need to be solved. The characteristics of data security and privacy protection of wearable health and medical devices were thus analyzed and compared with those of traditional health and medi-cal devices. The related studies and laws on domestic and foreign wearable health and medical devices were summa-rized, and the advances, experiences and problems in domestic and foreign wearable health and medical devices were analyzed and compared in order to provide reference for establishing the mechanisms underlying their data se-curity and privacy protection.

Objective To study the clinicopathologic characteristics and the prognostic factors of gastric stump cancer (GSC). Methods A total of forty-seven patients with GSC from Jan 2000 to Dec 2006 were enrolled in this study for retrospective analysis. Initial surgery was performed for gastric benign disease in 39 patients and for malignant disease in 8 patients, which were divided into 2 groups for analysis. The prognosis of all 47 patients were analyzed. Results The mean interval between previous gastrectomy and diagnosis of GSC was 24.4 years. Tumor developed mostly in the patients with Billroth- Ⅱ reconstruction, and male more than female. Tumor located at anastomotic site mostly, at stump stomach and cardia secondly. The mean interval for patients who had undergone their first gastrectomy for malignant disease was shorter than that with benign disease(P＜0.05). Histology, therapy and prognosis showed no significant differences between two groups (P＞0.05). Disease TNM stage and total radical gastrectomy were shown to be significant predictor for the outcome of patients with GSC (P ＜0.01). Conclusion Now the GSC patients with initial surgery performed for malignant disease are increased, which are no siginificant different to patients with benign disease. Early diagnosis and an aggressive surgical approach are crucial to achieve better outcomes for patients with GSC.

Objective To analyze Blimp1 expression difference in the latent and active of tuberculosis patients and the healthy , and assess possibility of as the new tuberculosis diagnostics molecules .Methods 60 patients with active TB (active tuberculosis group) ,50 participants with latent(latent tuberculosis group) ,and 50 healthy people(control group) were enrolled separately .Using fluorescence quantitative polymerase chain reaction were used to determin Blimp 1 mRNA expression in the peripheral blood mono-nuclear cells .Results Blimp1 mRNA expression level of the active tuberculosis group was 15 .35 times than the control group ,and 2 .21 times than the latent tuberculosis group ,the difference was statistically significant (P<0 .05) .Conclusion Blimp1 gene proba-bly plays a role in the immune response to tuberculosis .it provides new ideas for the laboratory diagnosis of tuberculosis and new clues for further exploring the pathogenesis mechanism of tuberculosis .

There have been many reports of clinical and experimental researches of microacupuncture therapy, the relevant systematic works, teaching materials and national standards in recent decades. It shows that microacupuncture system has been formed and its influence has been promoted. While the rapid development of microacupuncture therapy, there are the problems and contradictions on nomenclature, explanation of theoretical basis, optimal indications, and multiple systems and schools, etc. All the above have blocked the clinical application and development. It is considered that we need to unify the nomenclature, condense the theoretical basis, clear the optimal indications, promote the exchange and blend among different schools and sum up the outcomes by systematic review and data mining technique.

OBJECTIVETo compare the effects between mild moxibustion and specific electromagnetic spectrum therapy apparatus (TDP) for obsolete collateral ligament injury of interphalangeal joints.

METHODSSixty patients were randomly divided into a mild moxibustion group and a TDP group, 30 cases in each one. In the mild moxibustion group, pure moxa sticks were used at the affected digital joints locally for 20-30 min a time. In the TDP group, TDP was applied at the affected digital joints locally for 20-30 min a time. The treatment was given once a day for two courses, and 10-day treatment was made into a course. Visual analogue scale (VAS) for pain, swelling degree of the affected digital joints before and after treatment were observed and the clinical efficacy and safety were evaluated in the two groups.

RESULTSThe excellent rate was 56.7% (17/30) and the excellent and, good rate was 83.4% (25/30) in the mild moxibustion group,which were better than 36.7% (11/30) and 76.7% (23/30) in the TDP group respectively (both P < 0.01). After treatment the score of VAS and digital joints swelling degree were improved than those before treatment in the two groups (P < 0.01, P < 0.05), and the improvements of the mild moxibustion group were better than those of the TDP group (P < 0.01, P < 0.05).

CONCLUSIONMild moxibustion can apparently relieve the painful and swelling degree of obsolete collateral ligament injury of interphalangeal joints, which is superior to TDP.
