CONCLUSIONS:Shenqi fuzheng injection combined with Nimodipine tablet can significantly im-prove the serum hs-CRP and Fractalkine levels,blood rheology indicators,PAI-1 and FIB,and improve tPA activity.

AIM: To investigate the effect of ischemic preconditioning(IPC) on expression of nitric oxide synthase(NOS) in rat smallfor-size liver graft and its significance.METHODS: Sixty SD rats were randomly divided into 3 groups(n=10 pairs/group): nonwarm ischemia group(NWI);warm ischemic group(WI);and ischemic preconditioning group(IPC).The models of rat small-for-size liver transplantation were set up by two-cuff technique.Expression of eNOS mRNA and iNOS mRNA in hepatic tissue were detected by fluorescence-quantitating-PCR.RESULTS: Heptic expression of eNOS mRNA post-IPC was higher than that pre-IPC(P0.05).It was higher in IPC group than that in NWI and WI group(P

Objective To observe the dynamic changes of leptin and transforming growth factor (TGF)-β1 in formation of liver fibrosis in rats,and the role of leptin in liver fibrosis.Methods Six rats were served as normal control(0 week)and killed at the beginning of the study.Thirty-two rats were subcutaneously injected with 60%CCl4 to establish fibrotie models.The rats were than sacrificed at 3,6,9 and 12 weeks with eight each.Expressions of leptin mRNA,Ob-Rb mRNA,TGF-β1 mRNA and TGF-βRⅡmRNA in liver were detected by reverse-transcription polymerase chain reaction(RT-PCR).Expression of Smad3 and Smad7 proteins were determined by Western blot.The expression and loealization of leptin,Ob-Rb and TGF-β1 in liver tissue were detected by immunohistochemistry.Results The expression of leptin mRNA,Ob-Rb mRNA,TGF-β1 mRNA and TGF-βR Ⅱ mRNA in 0 week were 0.43±0.45,0.57±0.21,0.19±0.12 and 0.30±0.22,respectively,and increased to 1.27±0.19,1.70±0.29,1.70±1.00 and 2.14±1.02 at 12 weeks(P＜0.05).At the same times the level of Smad3 increased from 0.44±0.24 at 0 week to 1.75±1.05 at 12 weeks.While the expression of Smad7 was decreased from 1.35±0.12 at 0 week to 0.74±1.21 at 12 weeks(P＜0.05).The expressions of leptin,Ob-Rb and TGF-β1 were increased with the formation of the fibrosis(P＜0.01).Conclusions With the development of liver fibrosis,the expressions of leptin,Ob-Rb mRNA and protein are increased and improved the formation of the fibrosis.Its mechanisms may be correlated with up-regulation of TGF-β1,TGF-βR Ⅱ and Smda3 expressions and down-regulaton of Smad7 expression by leptin.

Objective The paper analyzes the operating patterns of the outpatient process and identifies the links needing reengineering so as to provide scientific basis for the optimal allocation of outpatient resources and process reengineering and prove the rationality and feasibility of using the queuing theory. Methods Using the methods of the queuing theory, the service time and the patients' arrival time at such service links as registration, billing and accounting, internal medicine, and gynecology in the outpatient department of a certain hospital were measured and the operational indexes at various links such as service intensity, average queuing length, average queuing time, average stay, probability of the service desks being idle, and the probability of the patients having to wait were calculated so as to estimate the rational number of service desks and the optimal value of the sum of the cost of waiting and the cost of service. Results Registration, billing and accounting , service intensity in internal medicine, personnel allocation, and queuing time were basically rational in the outpatient department of the hospital surveyed. One more physician should be added to the gynecology department so as to improve efficiency and reduce patients' waiting time and queuing length. There was currently a shortage of medical staff in the hospital. The cost of hospital input was moderate while the cost of waiting was on the high side. Conclusion It is rational and feasible to evaluate the efficiency of the outpatient process with the methods of the queuing theory. The method deserves to be spread.

Objective To compare the difference in recurrence rates between the endovenous laser therapy(EVLT) combined with percutaneous continuous circumsature (PCCS) and simplex EVLT following the treatment of great saphanous vein incompetence through the introduction of propensity score matching (PSM).Methods T the baseline data of 170 patients diagnosed with great saphanous vein incompetence who were treated in Punan Hospital in Pudong New District of Shanghai from 2009 to 2014 were retrospectively analyzed,of which underwent EVLT were 87 cases as EVLT group and EVLT combined with PCCS were 83 cases as EVLT +PCCS group.The groups covariate were balanced based on the PSM function of SPSS software using 1 ∶ 1 nearest neighbor matching method.The recurrence rates of the two groups were estimated by Kaplan-Meier method and the differences between the two groups were evaluated by Log-rank test.Results Sixty-seven pairs of patients were successfully matched.No significant difference between the two matched groups in the basic clinical features.Before PSM,the 1,2,and 3 year cummulative recurrence rates were 3.5％,5.4％ and 7.3％ in the EVLT group,and 0.9％,4.7％ and 4.7％ in the EVLT+PCCS group,respectively,there were no statistically significant differences between the two groups by Log-rank test (P =0.491).After PSM,the 1,2,and 3 year cummulative recurrence rates were 5.2％,5.2％ and 7.1％ in the EVLT group,and 0％,1.0％ and 1.0％ in the EVLT+PCCS group,there were statistically significant differences between the two groups (P =0.031).Conclusion The PSM methods can effectively balanced the covariates of groups in non-randomised study.EVLT combined with PCCS can effectively reduce the recurrence rate after the treatment of great saphanous vein incompetence.

OBJECTIVETo investigate the changes in serum interleukin-2 (IL-2) level in a hamster model bearing cheek pouch carcinoma after heavy ion beams irradiation.

METHODSThe serum levels of IL-2 were detected using enzyme-linked immunosorbant assay in 40 hamsters bearing cheek pouch carcinoma before and after exposure to heavy ion beam irradiation, with 8 normal animals as control.

RESULTSSerum IL-2 level was 0.16∓0.01 in the tumor-bearing hamsters before the irradiation, lower than that in the control group. After heavy ion beams irradiation at 4, 6, 8, and 12 Gy, serum IL-2 levels in the tumor-bearing hamsters were 0.18∓0.04, 0.22∓0.05, 0.15∓0.03, and 0.13∓0.04, respectively, showing a peak level after irradiation at 6 Gy and an obvious decrease following irradiation at greater doses.

CONCLUSIONHeavy ion beam irradiation causes alterations in serum IL-2 level with a dose-effect relation between them in hamsters bearing cheek pouch carcinoma.

Scavenger receptor CD36 could bind and endocytose oxLDL into macrophages which were then differentiated into foam cells that constitute the atherosclerotic lesion core, and was considered to be a potential target to treat atherosclerosis. In the establishment of the compound library of berberine (BBR, 1) analogues, we discovered that 13-hexylberberine (2) showed an antagonistic activity against CD36. Taking 2 as the lead compound, 21 derivatives were synthesized and their antagonistic activities were evaluated via an ELISA-like high-throughput screening (HTS) model. The primary structure-activity relationships were studied. It was indicated that the introduction of suitable groups at the 2- and 3-position of the aromatic ring A or at the 9-position of the aromatic ring D could enhance the activity. Among the 21 studied compounds, 7g bearing a benzyloxyl group at the 9-position provided a highest CD36 antagonistic activity with the IC50 value of 7.7 micromol L(-1). Besides, its antagonistic activity was further verified with Sf9 insect cell HTS model. So berberine analogues are a new family of CD36 receptor antagonists and worthy to be studied further.

Objective To approach the effect on mechanical barricade of the mucous membrane of small intestine caused by non-steroidal anti-inflammatory drugs(NSAIDs).Methods Thirty-two male SD rats were randomly divided into control group and model group.The rats of the model group were given 7.5 mg/kg diclofenac by gavage,bid;the rats of the control group were given the same dose of saline.Then thev were further randomly divided into two subgroups(n=8)at the first day and the fifth day after making the models to observe the scores of anatomical lesion on stomach and small intestine and the scores of tissue damage of mucous membrane and to quantitatively analyze the height of villi,as well as the thickness and the section area of mucous membrane with Carl Zeiss Imaging Systems.Observation of the change of ultrastructural organization of mucous membrane was carried out with transmission electron microscope.Results The mucous membrane of stomach of the model groups was slightly edematous.There was no difference between the scores of the model groups and control groups.It was seen that the mucous membrane of small intestine of the first day model group presented with erythema,anabrosis and ulcer.The ulcer was distributed along mesentery.The mucous membrane of small intestine of the fifth day model group showed bleeding,perforation and sinus tract formation,and the scores of anatomical lesion was higher than that of the control group(P＜0.05).The scroes of the lesions of the first and fifth day model groups were 3.5 and 5.0.The difference had statistical significance when compared with those of the control groups(the scores were O)(P＜0.05).Cell degeneration and cellular necrosis of epithelial mueosa of small intestine wag also seen in the first day model group.The top of villi was ablated.The height of the pile on jejunum was (126.9±32.0)μm and that on ileum wag(118.6±22.9)μm They were lower than those of the control group(P＜0.05).However there was no difference of the thickness and section area between them,but the thickness and section area showed a tendency of decrease.It was also seen that there were apomorphosis and sphacelism of epithelial cells in the fifth day model group.Some villi were ablated and laminae propna exposed.The height of villi on jejunum[(73.4±25.4)μm]and that on ileum[(109.3±17.6)μm]decreased significantiy.The thickness of mucous membrane[(123.8±51.6)μm and(165.7±37.4)μm]decreased alnd the section area[(2.48±1.01)mm2 and(3.27±0.76)mm2]became smaller(P＜0.05 vs control group).The mucous membrane of the villi on small intestine wag continuous but arranged disorderly.Cytochondriome swelled,endocytoplasmic reticulia expanded with different degrees,intercellular junction widened Dartly.The microviili in the fifth day model group were ablated more obviously and intercellular iunctions were broken and destroyed gravely.Conclusions Diclofenac can cause damage to the function of mucous membrane barricade of small intestine.It could also lead to shortening of the villi,thinning of the mucous membrane,ablation of the microvilli,and widening of the tight intercellular junction as the characteristic morphological change.

OBJECTIVETo study the kinetogenic effects of serum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala on the colonic smooth muscle cells of rats.

METHODSSerum containing Chinese materia medicas was made according to standard methods. Smooth muscle cells were isolated from the muscle layers of Wistar rat's colon, referred to modified Bitar's method. The contractile response of colonic smooth muscle cells to serum containing Chinese materia medicas (10%, 50%, 100% concentration) and other medicines (blank and 1 x 10(-3) mol/L acetylcholine) were separately observed. The contractility was presented by the decrease of the cell length between the drug groups and the control.

RESULTSSerum containing each Chinese materia medica can make dose-dependent contraction at different concentrations (P < 0.05), but the strongest effect of each serum had no significant difference (P > 0.05).

CONCLUSIONSerum containing Semen Arecae, Dandelion, Semen raphani and Atractylodes macrocephala can make notable contraction on colonic smooth muscle cells in rats.
