1.Management and drug therapy in elderly patients with diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 2014;30(10):876-878
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.
2.Efficacy and safety of PCNL with the use of different percutaneous renal access in treatment of renal calculi
Journal of Chongqing Medical University 2007;0(08):-
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
3.Research progress of checkpoint kinase 1 and DNA damage response pathway in tumors
Cancer Research and Clinic 2016;28(4):279-284
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.

5.Active Pseudomonas aeruginosa OprM efflux phenotype and genetic testing
International Journal of Laboratory Medicine 2010;31(6):538-539
Objective To take the initiative in Huaibei region of Pseudomonas aeruginosa OprM efflux phenotype and the presence of genetic analysis to explore the multi-drug resistant Pseudomonas aeruginosa and the active efflux mechanism.Methods assignment pump inhibitor carbonyl cyano-right-chlorophenyl hydrazone(CCCP)on Pseudomonas aeruginosa ciprofloxacin(CIP) reversal of the sensitivity tests to screen active efflux of Pseudomonas aeruginosa phenotype-positive bacteria;using PCR amplified active efflux phenotype-positive bacteria OprM genes.Results CCCP under the action of 36 Pseudomonas aeruginosa,24 strains of the CIP to improve the sensitivity of four times more active efflux phenotype positive rate was 66.7%(24/36);in OprM gene PCR extension by experiment,there are 16(44.4%,16/36)was amplified 848bp fragment of OprM.Conclusion active efflux phenotype in clinical Pseudomonas aeruginosa in widespread;OprM of Pseudomonas aeruginosa genes in active efflux of the most common bacteria.
7.Antimetastatic activity of liposomes containing muramyl dipeptides activiated macrophages.
Chinese Journal of Immunology 1985;0(06):-
The in vitro tumoricidal activity of peritoneal macrophages harvested from C57BL mice and activiated by li posomes containing water-soluble muramyl dipeptides (MDP) was measured by ~(125)I.UdR release assay. The results demonstrated that liposomes containing MDP could effectively activiate macrophages to become tumoricidal. The percentage of pu(?)monarymetastasis and the average metastatic pulmonary colonies of mice with experimental tumor metastasis decreased after intravenous injection of MDP encapsulated in liposomes. These results suggested that systemic administration liposomes containing MDP whichinduced macrophage activiation might provide a useful immunot heray for tumor, especial1y for pulmonary mini metastasis.
8.Effect of IFN-? on the growth of human cervical cancer transplanted subcutaneously in nude mice
China Oncology 2000;0(06):-
Purpose:To study the effect of interferon-? on the growth of human cervical cancer transplanted subcutaneously in nude mice.Methods:Twenty-eight nude mice transplanted subcutaneously with human cervical cancer were divided into 4 groups: control group,positive control group(DDP group),IFN-? low dose group(1.5?10 7 u/kg) and IFN-? high dose group(3.0?10 7 u/kg). Different drugs were used from day 14 after transplantation and all mice were sacrificed after 49 days. The weight of the mice and the volume of tumor were measured. FCM was used for measuring the proportion of cell cycle S+G 2 -M(%) in tumor cells. Results:The growth inhibiting rates in DDP group,IFN-? low dose group,IFN-? high dose group were 92.8%,73.8% and 93.1% respectively. Except for mice in DDP group,there was obvious increase in the weight of mice in other three groups. As for the proportion of S+G 2 -M(%),there was no difference in control group,IFN-? low dose group and IFN-? high dose group. Conclusions:IFN-? can inhibit markedly the growth of transplanted cervical cancer,which is correlated with the IFN-? dose. The mechanism of IFN-? inhibiting cervical cancer was not due to the suppression of cancer cell proliferation.
9.The Investigate of the Standard of Mental Health in Non-psychology Undergraduates
Chinese Medical Ethics 1994;0(05):-
Using the self-arrangede questionnaire,it is aimed to investigate the aititude of a normal university's 100 non-psychologystudents' attitudes to some of the porpular standard of mental health in undergraduates.Conclusions:(1)most of the non-psychology students are agree with the 30 items standards of the questionnaire.(2)While using "interpersonal relation","mental state","the attitude toward life","moral code","possessiveness"as the standaes of mental health of undergraduate,there is significant difference between non-psychology boys and girls.(3)While using "be good at copping with affairs","accepting dificiency","appropriate expression of emotion",as the standaes of mental health of undergraduate,there is significant difference between non-psychology sophomore and junior.

Objective To get new more sensitive signs reflecting cartilage degeneration,which were added to the present ARA differential criteria of knee osteoarthritis and to compare the sensitivity and specificity before and after new items.Methods Through review analysis of the clinical feature,radiography and operative presentation of 115 adult patients,the new signs reflecting cartilage degeneration as items were found,which were added to the present ARA differential criteria of knee osteoarthritis as new criteria.Then the 112 patients who have received either knee joint replacement or arthroscopy were re diagnosed with both the present ARA criteria and the new criteria.Sensitivity and specificity were calculated and compared.Results "Extensive knee joint tenderness" with cartilage degradation and "lockage on motion or a positive Apler test" were significantly related to the meniscus degradation.A 39 7% sensitivity of these patients was obtained using the present ARA clinical criteria,while it reached 70 6% using the new clinical criteria ( P 0 05).Conclusion The two new items added to the present ARA criteria help to increase the sensitivity for diagnosis of knee osteoarthritis without influence on the specificity.
