2.Advance in study of monitoring acute rejection of pancreas allograft transplant
Chinese Journal of Clinical Pharmacology and Therapeutics 2000;0(02):-
The syndrome of insulin-dependent diabetes mellitus(IDDM)includes not only abnor-mal glucose metabolism but also specific microvascular complications that include nephropathy,retinopathy and neuropathy.In the short term,improvement in the quality of life and possible prevention of further morbidity associated with diabetes makes pancreas trans-plantation an important therapeutic option,particularly when combined with a kidney trans-plant,in appropriately selected diabetic patients.The focus of the early management of the pancreas transplant recipient is the prevention of acute rejection.In this article we review the methods for clinical diagnosis of the early acute rejection due to pancreas transplanta-tion.
3.Progress on functions of lateral habenula and related mechanisms
Chinese Pharmacological Bulletin 2015;(11):1502-1504,1505
Lateral habenula ( LHb ) , which is situated in the dorsal diencephalon of all vertebrates, is an important component of the habenular complex. The neural network outlined in previ-ous studies indicates that LHb acts not only as an important relay station to link the forebrain with the midbrain regions that in-volved in regulating behavioral responses to reward and mediating the transmassion of negative feedback information, but also is closely connected with 5-HT system. Indeed, recently studies demonstrate that experimental manipulations of LHb are followed by behavioural alterations in relation to drug addiction, reward-a-version responses, pain, sleep, depression and so on. This arti-cle mainly reviews the mechanisms of LHb involved in all kinds of physiological activities.

The potential of 99mTc labeled P1, P4-di (adenosine-5')-tetraphosphate (Ap4A) for imaging experimental atherosclerotic plaques was evaluated in New Zealand white (NZW) rabbits. To label the 99mTc to Ap4A, stannous tartrate solution was used. 99mTc-Ap4A was purified on a Sephadex G-25 column. The radiochemistry purities of 99mTc-Ap4A were 85% to 91%. Biodistribution study revealed 99mTc-Ap4A cleared from blood rapidly. Thirty min after 99mTc-Ap4A administrated on NZW atherosclerotic rabbits, lesion to blood (target/blood, T/B) ratio was 3.17 +/- 1.27, and lesions to normal (target/non-target, T/NT) ratio was 5.23 +/- 1.87. Shadows of atherosclerotic plaques were clearly visible on radioautographic film. Aortas with atherosclerotic plaques also could be seen on ex vivo gamma camera images. Atherosclerotic abdominal aortas were clearly visible on in vivo images 15 min to 3 h after 99mTc-Ap4A administration. 99mTc-labeled Ap4A can be used for rapid noninvasive detection of experimental atherosclerotic plaque.

Objective To investigate the oxidative damage of lead acetate and sodium arsenite to human immortalized keratinocytes line HaCaT and the protective effects of TFBP extracted from the leaves of broussoneria papyifera. Methods Cultured immotlalized keratinocytes line HaCaT were treated by 0.1 mmol/L lead acetate and 5.0 ?mol/L sodium arsenite respectively,and 0~200 mg/L TFBP were added to the culture media at the same time. The contents of malondialdehyde(MDA?雪,the activities of superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)in the cultured HaCaT cells were determined. The protective effects of TFBP at different concentrations were evaluated. Results 0.1 mmol/L lead acetate caused oxidative damage to HaCaT cells markedly. When the concentrations were increased to more than 100 mg/L,TFBP had certain protective effects from the damage induced by lead acetate with the decrease of the MDA levels from 4.23 ?mol/L to 1.87 ?mol/L and the increase of the SOD levels from 25.90 U/mg Pro to 37.12 U/mg Pro,while the activities of GSH-Px showed no significant change. The activities of SOD and GSH-Px were increased in the cultured cells treated by sodium arsenite with 150 mg/L and 200 mg/L TFBP. Conclusion Lead acetate and sodium arsenite could cause significant oxidative damage to HaCaT cells and TFBP had certain protective effects on the cells from the oxidative damage induced by lead acetate and sodium arsenite under the conditions of this study.

Objective:To investigate the expression of anti-endothelial cell antibodies(AECA) in patients serum with anti-neutrophil cytoplasmic antibody( ANCA) negative pauci-immune deposition type crescentic glomerulonephritis and its relationship with clinical signatures. Methods:We selected 94 pauci-immune deposition type crescentic glomerulonephritis patients from 2010 to 2015 treated in our hospital,45 of which with ANCA-negative( observation group) and 49 cases of ANCA-positive patients ( control group) , AECA levels of each groups serum were detected by Western blot test. Results: The average age of the observation group and Bermingham vasculitis activity score(BVAS) respectively (41. 08 +9. 43) years old and (15. 03 +3. 82),significantly lower than the control group (P<0. 05);the observation group had fever,joint pain accounted for 26. 67% and 13. 33%,significantly lower than the control group ( P<0. 05 );the observation group of nephrotic syndrome accounted for 48. 89%, higher than the control group ( P<0. 05);observation group positive rate of serum AECA was 46. 67%,significantly lower than the control group 81. 63% (P<0. 05);the observation group IgG-AECA identified 7 proteins,while the control group had identified 11 proteins,of which the observation group the positive rate of anti 90 kD antibody was 13. 33%( 6/45 ) , significantly lower than the control group 51. 02%( 25/49 ) ( P<0. 05 );observation group of anti 76 kD antibody positive patients had rash ratio of 100%, significantly higher than negative patients ( P<0. 05),anti 200 kD antibody positive the BVAS score of the patients was (18. 02 + 2. 51),which was significantly higher than that of the negative patients ( P < 0. 05 ) . Conclusion: The different level of AECA in ANCA negative pauci-immune crescentic glomerulonephritis patients may be associated with certain clinical manifestations;clinical manifestations differences between the ANCA negative and positive patients may be associated with different expression of the AECA related,the detail need a further study.

The paper introduced the multi-site physician practice operational in the modes of hospital departmental support,hospital trusteeship,and public-private hospital management,and summarized the merits of such a practice adopted in the background of cooperative hospital operations as follows.A cooperation of common interests enjoys supports of all stakeholders and minimum resistance;better policies and conditions mobilize physicians'incentives; better continuity of medical practice; better public benefits of the hospital.The paper also probed into such issues as setbacks of the practice in such a background,complicity of medical disputes definition and resolution,possible talent drain of public hospitals,and possible impacts on branding and core competence of public hospitals.
