1.Sentinel Lymph Node Detection in Endometrial Cancer and Clinical Significance of Micrometastases
Chinese Journal of Clinical Oncology 2009;36(24):1426-1429
Sentinel lymph node (SLN) detection in endometrial cancer is still in the exploration stage. But a good many studies have confirmed the feasibility of SLN detection in patients with early endometrial cancer. Higher detection rate of SLN can be achieved by the combination of blue dye and radiocolloid. Compared with intracervical injection, more injections at different sites of the uterine corpus and hysteroscopic injection may improve SLN detection rate and para-aortic SLN detection rate. SLN detection rates are also related to some other factors such as the amount of tracers, the interval between injection and detection, and the depth of myometrium invasion. Serial-step section of SLN combined with immunohistochemistry staining with anti-cyto-keratin may improve the detection of micrometastasis (MM) in SLN. SLN procedure can detect MM which cannot be found by traditional pathological techniques. The ultrastaging will allow better stratification of patients at intermediate risk and can provide valuable informaiton for the selection of adjuvant therapy, thus decreasing the recurrent rate.
2.Changes of PGE_2 and cAMP levels in plasma and c. s. f. during TNF-induced fever in rabbits
Chinese Journal of Pathophysiology 1986;0(02):-
Thirty New Zealand albino rabbits of both sexes were used for the experi-ments which was (1) To observe the febrile response induced by microinjection of TNFinto the lateral ventricle; (2) To measure the PGE_2 & cAMP contents of the plasma andcerebrospinal fluid. The results showed that injection of TNF (50ng/each) into the lateralventricle did induce a definite raise of body temperature (T=0.79?0.14℃). The PGE_2concentration increased markedly in c. s. f. while that in plasma remain unchanged ascompared with the control. However cAMP lever in both, plasma and c. s. f. had nochange. These results suggested that (1) The injection of TNF into the lateral ventriclecaused a raise in PGE_2 synthesis in the brain while there was no alterations of PGE_2found in peripheral blood (2) The increase in PGE_2 didn't followed by an increase incAMP which indicated that the fever induced by TNF must have a different mechanismfrom that induced by leucocyte pyrogent (LP or In-1). PGE_2 might be involved in thefever inducing mechanism but these results don't support the hypothersis that the raiseof PGE_2 level may increase the cAMP content which in turn reduced the fever.

5.Influence of digestion time on the primary culture of cardimyocytes
Journal of Medical Postgraduates 2015;(6):564-568
Objective Primary myocardial cell culture , as an important technique for in vitro experiment , provides an essen-tial basis for the establishment of models of cardiovascular diseases .This study aimed to investigate the influence of digestion time on primary myocardial cell culture and to find some simple primary culture methods for obtaining myocardial cells with high survival rate , purity, and activity. Methods We used only one collagenase for repeated digestion of myocardial tissue for 8 and 10 minutes, re-spectively , and obtained high-purity cardiomyocytes by differential adhesion and Brdu inhibition .We observed the morphological chan-ges of the cardiomyocytes under the optical microscope , measured their vitality according to the beating frequency in different regions , and counted the living cells after typan blue staining. Finally, we established a model of myocyte hypertrophy for verification of cell activity and compared the cell surface area between the experimental ( angiotensinⅡ) and control ( 10%FBS DMEM [H +] medium ) groups. Results After cultured for 48 hours, the primary cardimyocytes in the 10 min group mostly extended pseudopodia , in-terwoven into a network and gradually forming cell clusters , with obviously powerful beating and contraction .After isolation and purifi-cation, the average survival rate of the cells was >90%, significantly higher in the 10 min group than in the 8 min ([95.4 ±0.8]%vs [93.0 ±0.8]%, P<0.05).The positive expression rate of cardiac α-actin was >95%in both of the groups.After cultured with angiotensinⅡfor 48 hours, the 10 min group showed a significantly increased level of atrial natriuretic peptide (ANP) (20.8 ±0.67 vs 15.8 ±0.48, P<0.05) and cell surface area ([34.77 ±8.43] μm2 vs [14.11 ±4.29] μm2, P<0.05) as compared with the 8 min group. Conclusion Primary culture of cardimyocytes with 8 min digestion is simple and time-saving, and what is most important , can obtain high-quality cardiomyocytes .

Chinese Journal of Biochemical Pharmaceutics 2017;37(8):133-134
Objective To study the effect of different doses of dexmedetomidine combined with propofol and remifentanil in patients undergoing abdominal surgery. Methods 200 cases of abdominal operation in our hospital from January 2015 to August 2016 were selected as the subjects, and were randomly divided into the experimental group and the control group, with 100 patients in each group. Patients in the control group received 0.4μg/kg, dexmedetomidine hydrochloride injection combined with propofol and remifentanil anesthesia, and the experimental group received 0.8μg/kg, Dexmedetomidine Hydrochloride Injection anesthesia.
