Nowadays,aging is the general trend of population development in the world.Type 2 diabetes is one of the most common chronic diseases in the elderly.Because of the atypical symptoms and signs,accompaniment of chronic cardiovascular disease and vulnerability to low blood glucose in the elder patients with diabetes,we should to make safe,effective,and individualized therapeutic programs for them.This paper will review the current prevalence,characteristics,and oral drug selection among elderly individuals with T2DM.

The main reason of recurrence and metastasis in breast cancer is the resistance for the radiotherapy and chemotherapy,and the mechanism of radio-resistance and chemo-resistance may be related to the DNA damage response (DDR).There is a complicated system of the DDR pathway,including cell cycle checkpoint,DNA repair,transcription and apoptosis to maintain the integrity of cell genes.In the cancer treatment,DDR occurs in various kinds of cytotoxic drugs and radiation to cause genetic damage,which limits the curative effect of chemotherapy and radiotherapy.This promotes the targeted therapy of DDR pathway,especially checkpoint kinase 1 (CHK1).Recently,the new viewpoint supports that CHK1 is a main marker of the DDR pathway activation,which shows that CHK1 not only activates the check point but also affects the DNA repair and apoptosis directly.Thus,the role of CHK1 in DDR will promote CHK1 inhibitor to be one of the new treatment strategies for the cancer patients who resist the radiation and chemotherapy.

Objective:To investigate the clinical efficacy and safety of PCNL with the use of different percutaneous renal access in treatment of renal calculi.Methods:Percutaneous renal minimal access(F14～F16)or small access(F18～F20)was established randomly in 142 patients,and PCNL were performed in all patients.The clinical parameters including operative time,complication and stone-free rate were compared in the two groups.Results:The operative time of simple renal calculi were(78.3?15.6)min and(91.2? 18.2)min(P0.05)in small access group and minimal access group respectively.The operative time of complicated renal calculi were(115.3?20.1)min and(130.7?28.7)min(P

As a new technique, photedynamic therapy was introduced in the end of 1970s and has been put into clinical application from experimental tests in recent years. Its mechanisms was established on the basis that a series of special typed cells and tissues could selectively absorb photosensitive drugs and generate photore-sponsive effects by light irradiation of definite wavelengths. Currently, the photodynamic theraputics is applied mainly in non surgical treatment of tumor betided in body superfacial and hollow viscus. Its application area has been expanded unceasingly in modern clinic due to the discovery of the selective aggregation of photoresponsive drugs to many pathological tissues and pathogenic microorganisms other than tumors, and the development of new photoresensitizer. In this paper, review is given on the effect mechanisms, the light sources and photosensitizer, as well as the application of photodynamic treatment of tumors in head and neck and its treatments of mucosal dis-ease and oral pathogenic microorganism infected diseases.

Objectives To study the reliability,validity and feasibility of the Chinese version of memory alteration test(M@T).Methods Cross-sectional survey with a convenience sample was employed to interview 220 elderly people over 60 years old,39 patients with mild cognitive impairment(MCI),20 with Alzheimer's disease(AD),and 161 normal cognitive elderly.The survey was,then evaluated with internal consistency,content validity,criterion validity,principal component/factor analysis and influencing factors.Results A Cronbach's α coefficient of 0.818 was obtained in M@T. The correlation coefficients which were the score of the subtest and the total were 0.5-0.9.The correlation coefficient of the scores of the Mini.mental State Examination(MMSE)and the M@T Was 0.933.The 5 factors were extracted with the factor analysis,which could explain the total variance of 69.449%,and the corresponding factors of the proieets have a satisfied amount of factor loading(≥0.4).There were significant diffeFences in the score of M@T among the different cognitive level groups with good discriminant validity(cognitive normal group:39.0±3.7,MCI group:29.0±3.7,AD group:16.9±3.7;F=498.419,P<0.05).There were no significant differences in the score of M@T among the different gender,age,occupation and education level groups.Conclusions The Chinese version of M@T has good reliability and validity and feasibility.The score of the M@T is not affected by gender,age,occupation,education level and other factors.

Magnesium and its alloys possess the features of low density,high strength and rigidity,good biocompatibility and biodegradability.Their elastic modulus is similar to human bone,which endows them with a broad application prospect in the field of orthopedic biomedical materials.This paper reviews the current research status of magnesium and its alloys as the orthopedic implant materials and as porous scaffold materials in bone tissue engineering.Methods to improve corrosion resistance of magnesium-based metals ale briefly described as well.

Human cervical cancer oncogene(HCCR) is newly identified in cervical cancer tissues,and expresses in most human tumors. Resarches show that HCCR is a candidate marker for human hepatocelular carcinoma and breast cancer. Moreover,the expression of HCCR is regulated by mitogen-activated protein kinase (MAPK)and phosphatidylinositol 3-kinase signal pathway. The proliferation,apoptosis,migration and invasion of tumor cells could be inhibited by siRNA of HCCR.

The rapid cooling contracture in myocardial protection is getting more and more attention. Rapid cooling contracture is referred to as the undepolarized myocardial contracture induced by rapid cooling, which is related with the sudden increase of Ca2+. The Ca2+ released from sarcoplasmic reticulum subsequently causes myocardial contracture through the myofilaments sliding. Its deleterious effects include: more energy consumption, impaired cardiac function, Ca2+ overload, et al. And some investigators have put forward some principals to prevent the bad influences of rapid cooling contracture.

Objective To explore the relationship between transitional care model and diabetic patients. Methods 112 patients with type 2 diabetes mellitus were divided into observation group and control group according to random number table. Control group used the doctor as the center patient management mode. The observation group used thepatient-centeredpatient management, application of home nursing service. Results Glycosylated hemoglobin (HbA1c), triglyceride (TG), high-density lipoprotein (HGL), 2 h postprandial blood glucose (2hPBG), fasting blood glucose (FBG), body mass index (BMI) of observation group before treatment respectively were (11.2±2.4)%, (3.7±1.3) mmol/L, (0.5±0.2) mmol/L, (13.6±2.4) mmol/L, (11.8±2.9) mmol/L, (25.9±4.9) kg/m2. Patients discharged from hospital after care for 3 months respectively were (6.8±0.9)%, (1.0±0.3) mmol/L, (2.5±0.4) mmol/L, (8.9±1.5) mmol/L, (6.8 ± 2.0) mmol/L, (20.8 ± 5.8) kg/m2. There was statistically significant difference (t=3.5-6.6,P<0.05). Control group before treatment respectively were (11.9 ± 3.6) %, (3.8 ± 1.5) mmol/L, (0.6 ± 0.3) mmol/L, (13.9 ± 2.9) mmol/L, (11.6 ± 3.2) mmol/L, (25.9 ± 6.8) kg/m2,while patients discharged from hospital for 3 months respectively were (10.9±3.4)%, (3.3±0.7) mmol/L, (0.7±0.2) mmol/L, (12.8±4.2) mmol/L, (10.6± 2.6) mmol/L, (25.1 ± 6.6) kg/m2, there was no statistically significant difference (t=0.05-1.36,P>0.05). Patients discharged from hospital after 3 months, perception, diet, medication, exercise adherence score of observation group was (34.98 ± 5.67), (41.98 ± 5.00), (40.29 ± 5.60), (40.45 ± 7.21) points, which were obviously higher than (21.18±4.75) , (28.46±4.26), (21.88±4.58), (20.98±2.69) points of control group, the difference was statistically significant (t=13.96-19.03,P<0.01). Conclusions Using home nursing service mode in type 2 diabetes care is helping to improve blood sugar levels and improve patient compliance after discharge, fully improve the patients′prognosis.
