AlM:To explore the efficacy and safety of mitomycin C used in trabeculectomy by analyzing intraocular pressure and blood flow.METHODS:A total of 103 patients with glaucoma were divided into 2 groups randomly, and all patients were treated with trabeculectomy, while patients in the observation group were given mitomycin C extra. At 6~12mo follow-up were completed after operation, and the clinical efficacy, complications and hemodynamic characteristics of central retinal artery were compared between groups.RESULTS: The clinical efficacy of the observation group was higher than that of the controls (P<0. 05). There was no significant difference in complication rate between groups (P>0. 05), but the complication type was differentiate to some extent. Low intraocular pressure and photophobia symptoms occurred mostly in the observation group, while cicatricial obstruction occurred mostly in the controls. Before treatment, there was no significant difference in hemodynamic characteristics between groups (P>0. 05). One month after treatment, the peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of the observation group were obviously lower, while resistance index ( Rl ) and pulsatility index ( Pl ) were higher than those of the controls, the difference was statistically significant ( P<0. 05). Six months after treatment, the PSV and EDV of the observation group were obviously higher, while Rl and Pl were lower than those of the controls, the difference was statistically significant (P<0. 05).CONCLUSlON:Mitomycin C has a short-term harmful effect on glaucoma patients after trabeculectomy, but its long-term effect is safe and reliable.

Interventional treatment via portal vein system plays an important role in treating some liver diseases,such as interventional treatment for portal vein tumor thrombus,portal hypertension with liver cirrhosis,portal vein thrombosis and selective portal vein embolization inducing compensatory hypertrophy of the remnant liver.The author introduces the routes,methods and efficacies of the interventional treatment via portal vein.

Objective:To investigate and compare the effect of sodium hyaluronate and chitosan in the prevention of thyroid post-operative adhesion. Methods:Totally 84 patients with thyroid operation in our hospital from August 2012 to August 2013 were select-ed, and according to the admission time, the patients were respectively divided into group A and B with 42 cases each. In order to pre-vent postoperative adhesion, group A was treated with sodium hyaluronate, and group B was treated with chitosan. The clinical curative effect of the two groups was compared. Results: The adhesion rate in group A was 14. 3%(6/42), which was higher than that in group B (3/42 7. 1%), while the difference was not statistically significant (P>0. 05). All the patients showed no bleeding, aller-gies and other adverse reactions, only in group A, 2 mild infection (4. 8%) occurred. The adverse reactions in the two groups were without significant difference (P>0.05). Conclusion: Sodium hyaluronate and chitosan both have the preventive effect on thyroid postoperative adhesion with similar efficiency and adverse reactions.

In this paper, a systematical and retrospective review was made on how the drug purchasing system of Chinese healthcare institutions has evolved from decentralized purchasing to centralized purchasing based on four stages as budding stage, initial stage, adjustment stage and deepening stage. In each stage, the working characteris-tics, achievements and problems have been analyzed. Targeting at the problems and challenges confronted with cur-rent drug purchasing, recommendations was made to reform and improve public hospitals’ centralized purchasing sys-tem, such as persisting centralized purchasing online at provincial level, sticking to “four favorable” principles, breaking through the mechanism of compensating medical cost with drug-selling profits, promoting coordinated inter-action reforms in healthcare insurances, distribution and pricing, strengthening comprehensive services and supervi-sion, etc.

To explore an appropriate teaching model in medical computer science in China, this paper, based on the actual state of medical computer science,points out that PBL teaching model accords with our disciplinary goal in training medical education talents in medical university and discusses how PBL teaching model is applied to medical computer science.

Androgen deprivation therapy can effectively suppress the progression of prostate cancer, but accumulating evidence for the relationship of testosterone with prostate cancer challenges the conventional wisdom. High levels of testosterone are not risk factors for prostate cancer, nor promote its development. On the contrary, a low testosterone level indicates a worse pathological stage. So far there has been no strong evidence to prove the role of testosterone in the occurrence and progression of prostate cancer. Therefore, the relationship between testosterone and prostate cancer is quite complicated and deserves further investigation.

Objective To study the effect of a distal protection device (Pereusurge GuardWire: GW) on epicardial blood flow and myocardial perfusion in primary percutaneous coronary intervention. Method Acute STEMI patients treated with primary PCI were eligible to be studied. Inclusion criteria were: (1) within 12 hours from the onset of chest pain;(2) culprit leision with diameter stenosis≥70% and TIMI flow grade≤2. Exclusion criteria were:(1) patients undergoing thrombolytic therapy before PCI; (2) a culprit lesion in the left main coronary artery;(3)reference vessel diameter

Biocontrol bacteria 308R(pKSH) with hrpN of Erwinia amyloyora. It can secrete the Harpin protein which can induce plant resistance. After successive growth in antibiotic-free LB medium for 50 generations, only 23.1% of the cell still retained the plasmid pKSH, in comparison with 4.75% of the cosmid pCPP430. Sprayed onto the leaves of tomato, the recombinant strain maintained a population density of over 10~ 5 cfu/cm~ 2 when kept under high humidity in thirteen days, but if without humidity, the strain keep 10~ 4 cfu/cm~ 2 over in five days. On the tomato leaves, the stability of the recombinant strain 308R(pKSH) was higher than the strain 308R(pCPP430). The experiment indicated that the recombinant strain 308R(pKSH) had higher stability compared with the strain 308R(pCPP430), but that was not enough. In this paper reasons for unstability and strategies for improving were discussed for the recombinant strain.

By using ~3H—TdR incorporation and CTLL—2 cell line,we observed effects of RU486,anantagonist of type Ⅱ glucocorticoid receptor,on dexamethasone inhibition of lymphocyte prolifer-ation and interleukin—2(IL—2)production in rat spleen.It was shown that RU486 obviouslyantagonized the inhibitory actions of dexamethasone on lymphocyte proliferation and IL—2 pro-duction.By means of dot hybridization and Northern blot analysis,effects of dexamethasone andRU486 on IL—2 gene expression were investigated in lymphocytes of rat spleen.The datademonstrated that dexamethasone markedly decreased IL—2 mRNA production,RU486 alonedidn't affect IL-2 mRNA levels,but obviously reversed dexamethasone-mediated downregala-tion of IL—2 mRNA production in ConA—activated lymphocytes.These results suggest thatthe above effects of dexamethasone may be mediated by glucocorticoid receptor in lymphocytesof rat spleen.
