1.Experimental study on radio frequency ablation(RFA) combined with chemotherapy drug for treatment of Hepatic VX_2 carcinoma rabbit model
Journal of Chongqing Medical University 1987;0(01):-
Objective: To observe the therapeutic effects of RFA combined with chemotherapy drug on hepatic VX: carcinoma in rabbits and to explore its mechanism.Methods: 40 rabbit models with VX: carcinoma were used for this study.they were divided into four groups at random.We watched the changes in serolog ALT,diameter of tumor and pathomorphology.And we also utilized terminal deoxynucleotidyl ransferase-mediated dUTP nick-end-labeling and immunohistochemistry to observe the apoptosis and proliferation.Results: ⑴The blood ALT significantly increased at the first day after treatment,then descended at the third day,and at the seventh day it descended to the level of pretreatment stage in group RFA combined with epirubicin.(2) The diameter of tumor showed significant difference between combined treatment and other groups.(3) Two weeks after treatment,the complete necrotic area slightly extended.it was clearly seen that the zone consisted of normal liver constitution,inflammation hyperemia zone and amorphous necrotic constitution by HE staining in combined treatment group.(4) The apoptosis index of the combined treatment group was bigger than that in other groups by TUNEL technology,but the PCNA index in the combined treatment group was lower than other groups.They all had significant difference.There was negative correlation between apoptosis index and PCNA index in the combined treatment group(r=-0.745,P

The progress of modality therapy has improved both survival rate and quality of life of retinoblastoma(RB) patients.However,some problems are still left and unsolved.Parts of the RB relapse after they are treated for the first time.Even more remarkable,the related individuals to the RB patients run a risk of RB.Gene diagnosis and treatment are emerging and appear to solve these problems.Some researches in developed countries and Hong Kong have successfully made progress in gene diagnosis of RB.However,the detection rate of Rb1 gene mutation is very low.Researches documented for many years that gene diagnosis for RB is extremely complex,so we should go further to achieve a goal of gene diagnosis.Gene diagnosis of RB is still an initiation in China.We should strengthen relevant study and spread this technique.
5.Portable instrument for arteriosclerosis assessment.
Chinese Journal of Medical Instrumentation 2014;38(1):6-10
A portable instrument for arteriosclerosis assessment containing sensor module, acquisition board and embedded module was developed for home care in this paper. The sensor module consists of one ECG module and three pulse wave extraction modules, synchronously acquiring human ECG and pulse wave signal of carotid, radial, and dorsal, respectively. The acquisition board converts the sensor module's analog output signals into digital signals and transmits them to the embedded module. The embedded module realizes the functions including signal display, storage and the calculation and output of pulse wave velocity. The structure of the proposed portable instrument is simple, easy to use, and easy to expand. Small size, low cost, and low power consumption are also the advantages of this device. Experimental results demonstrated that the proposed portable instrument for arteriosclerosis assessment has high accuracy, good repeatability and can assess the degree of atherosclerosis appropriately.

7.Analysis of cleaning quality of medical instruments in disinfection supply room by alkaline cleaning agent
Chinese Journal of Biochemical Pharmaceutics 2017;37(9):375-376
Objective To observe the application of alkaline cleaning agent in disinfection and supply room cleaning of medical devices, to evaluate the cleaning quality. Methods The 800 contaminated medical instruments collected from February 2016 to February 2017 in municipal maternal and child health hospital were divided into control group (February 2016 to August 2016) and study group (September 2016 to March 2017 ) according to different time periods,with 400 pieces in each group.In the reference group, the instrument was washed with multienzyme detergent, and the study group was cleaned with alkaline detergent. The cleaning of 2 groups of instruments was observed and compared. Results The total excellent and good rate of instrument cleaning in the study group was 97.25% (389/400), in the reference group was 89.50%(358/400), the difference between the two groups was statistically significant (P<0.05); the cleaning safety, practicality, economy, comprehensive score difference of the study group was significantly better than the reference group (P<0.05). Conclusion The effect of alkaline cleaning agent used in disinfection supply room cleaning medical instruments is remarkable, and the equipment residue and microorganism can be effectively eliminated, and the utility model has the advantages of high safety and low economic cost, and has the important practical value.
8.Immunomodulatory features of chemotherapeutics
Journal of Medical Postgraduates 2004;0(01):-
Chemotherapeutic drugs conventionally used for their cytotoxic activity can also exert their influence on the immune system by grooming the tumor microenvironment,abrogating immune tolerance and inciting immune reconstitution.Due to their immunomodulatory features,chemotherapeutics,used as a preconditioning regimen and combined with subsequent immunotherapy,can mobilize the immune system to generate antitumor immune response.The synergy between chemotherapy and immunotherapy has brought some enlightenment to the development of new protocols for cancer treatment.
9.Administration status of enteric-coated aspirin among diabetic patients in Xujiahui subdistrict of Shanghai
Chinese Journal of General Practitioners 2011;10(6):404-405
The administration status of enteric coated aspirin in 348 diabetic patients aged over 40 from Xujiahui Subdistrict of Shanghai was surveyed. One hundred and two out 348 patients ( 29. 3% ) used aspirin regularly, among them only 36 cases used the correct dosage (75 - 162 mg/d), accounting for 10. 3% (36/348) of all patients surveyed. The results indicate that aspirin was not used properly in diabetic patients to prevent the heart and cerebrovascular diseases,and it is necessary for medical providers to promote health education for diabetic patients.
10.Clinical analysis of 145 death cases from the department of emergency internal medicine
Clinical Medicine of China 2011;27(3):276-278
Objective To summarize and analyse the clinical data of death cases in the department of emergency internal medicine. Methods The clinical data of patients presenting at the department of emergency internal medicine from January 2005 to July 2010 were analyzed retrospectively. Results Among 13 211 patients of department of emergency internal medicine, 145 died. More cases died in winter( 32.0% , 39/122 ).More than half of deaths occurred within 6 hours after admission( 54.5% ,79/145 ). The top six death causes were sudden death, pulmonary infection, cerebrovascular accident, advanced cancer, gastrointestinal bleeding,cardiovascular diseases and the occurrence rates were 18. 6%, 13.8%, 13.8%, 10.3%, 9. 7% and 9.0%respectively. Conclusion The first three death causes in department of emergency internal medicine were sudden death, cerebrovascular accident, pulmonary infection. Prevention of these diseases, cooperation between emergency department and other departments and special training on standardized treatment of critically ill patients should be enhanced.
