Chinese Journal of Primary Medicine and Pharmacy 2009;16(5):771-772
Objective To investigate the effect of batroxobin on the plasma levels of endothelin (ET) and calcitonin gene-related peptide(CGRP) in patients with acute cerebral infarction(ACI). Methods 60 patients with ACI were randomly divided into therapy group(n = 30) and control group(n = 30),500 ml of 5% GS plus 1.0g ramme of Troxerutin was intravenously dripped par day and ticlopidine 250mg/day in the control group. Based on the control group therapy,Batroxobin was intravenously dripped with 10U on the 1st day and 5U on the 3rd and 5th day for seven days. The plasma levels of ET and CGRP were detected pre and post treatment by radioimmunoassay. Results Plasma levels of ET and CGRP in batroxobin therapy group post treatment ( 81.25±27.38 ) ; ( 44. 13±13.30) ng/L were significantly different from those pre treatment(109. 83±38.24) ; (24. 73±13.59) ng/L (all P<0. 01 ) ,and were also significantly different from those post treatment in the control group(98.07±30. 39) ; (37.02±12. 41 )ng/L (all P<0. 01 ). Conclusion Batroxobin can accommodate the equilibration between ET and CGRP, and protect brain cell and blood vessel endothelial cell.

Objective To evaluate the effect of minocycline on the long-term cognitive function after partial hepatectomy in mice.Methods Sixty-four male C57BL/6 mice,aged 3 months,weighing about 20 g,were randomly divided into 4 groups (n =16 each) using a random number table:control group (group C),partial hepatectomy group (group O),PBS group,and minocycline group (Mino group).At 3 days after partial hepatectomy,the rats underwent Morris water maze test.The animals were sacrificed and their hippocampi were immediately removed for determination of tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) mRNA (using real-time fluorescent quantitative PCR) and nuclear factor kappa B (NF-κB) expression in the nuclcar protein of the cells (using Western blot).After the mice regained consciousness after operation,minocycline 50 mg· kg-1 · d-1 was injected intraperitoneally for 30 consecutive days in Mino group,while the equal volume of PBS was given instead of minocycline in group PBS.The parameters mentioned above were then recorded.Results Compared with group C,the escape latency and swimming distance were significantly prolonged,and the expression of TNF-α mRNA,IL-6 mRNA and NF-κB was up-regulated in group O (P < 0.05).Compared with group PBS,the escape latency and swimming distance were significantly shortened,and the expression of TNF-α mRNA,IL-6 mRNA and NF-κB was down-regulated in group Mino (P < 0.05).Conclusion Minocycline can improve the long-term cognitive function after partial hepatectomy in mice and inhibition of inflammatory responses in hippocampi is involved in the mechanism.

Objective: To analyze the influences of implementing essential medicine system on primary medical institutions and give suggestions. Methods: Using system dynamics method to construct the compensation mechanism model for primary medical institutions. Compare the growth in revenue and expenditure of primary medical institutions before and after essential medicine system implementation. Results: After the implement of essential medicine system, the growth in total expenditure and total income of primary medical institutions is steadier; when the annual growth rate of government financial subsidies invested more than 13%, the growth in total receipts will keep balance. Conclusion: It’s better to guarantee the government financial subsidies invested in time, raise medical service price properly and establish comprehensive compensation mechanism for implementing compensation mechanism of primary medical institutions.

Objective To explore the role of OAZ gene in the pathogenesis of systemic lupus erythe-matosus (SLE) by using RNA interfering technique. Methods Peripheral blood mononuclear cells (PBMC) from SLE patients were collected. Each sample was equally divided into four groups for cell culture in 96 well plates. Specific siRNA for OAZ and GAPDH were concordantly added to the experimental group and the positive control group, while nonspecific siRNA was added to the negative control group and only culture medium was added to the Mock control group. Cells and supernatants were harvested after culturing for 72 hours, then RNA was extracted and reverse transcripted to cDNA. OAZ, Id1, Id2, Id3, Id4 mRNA expression levels were analyzed by using real-time PCR. Levels of IFN-γ, IL-4, IL-10, IL-12, IL-21, CCL2, ANA in the supernatant were tested by ELISA. Relationships between the expression levels of OAZ mRNA with levels of cytokines and ANA were analyzed. Results OAZ, Id1, Id2, Id3 gene mRNA expression levels (△Ct: 12.5±1.4, 8.9±1.5, 4.3±0.8, 8.04±1.1) in the experimental group were significantly decreased comparing to those in the negative control group (△Ct: 10.2±1.1, 6.5±1.2, 2.4±1.3, 6.2±1.2 respectively, P<0.05). Levels of IFN-γ, IL-10, IL-12, IL-21 and ANA in the experimental group were significantly lower than those in the negative control group (P< 0.05), but level of CCL2 was higher than the negative control group (P<0.05). Difference of OAZ mRNA expression levels (△△Ct) between the experimental group and the negative control group was negatively correlated with changes of ANA, IL-21 levels, but positively correlated with changes of Th1/Th2, CCL2. Conclusion OAZ siRNA can effectively reduce the expression of genes involved in the OAZ signaling pathway in SLE. OAZ may lead to abnormal production of ANA via regulating Id genes and cytokines.

Clinical data of 23 patients with T2a bladder cancer admitted from March 2008 to August 2013 were retrospectively analyzed.Among 23 patients,11 cases were treated with transurethral resection (TURBT) plus arterial catheterization chemotherapy (study group) and 12 cases were treated with radical cystectomy (control group).The overall survival time and recurrence free survival time of two groups were compared.Patients in study group were followed up for 20-68 months,recurrence occurred in 5 cases (5/11),including 4 cases of invasive recurrence;patients in control group were followed up for 2 ~86 months,1 case had superficial recurrent and underwent TURBT,2 cases dead due to bladder tumor.During the course of chemotherapy,the main adverse effects were digestive reaction (7/11),fever (4/11),bone marrow suppression (2/11),symptomatic treatment was given,which was tolerated.There were no significant differences in overall survival time and recurrence free survival time between two groups (P > 0.05).The quality of life of study group was better than that of control group (P < 0.05).It is suggested that the arterial interventional chemotherapy combined with transurethral resection for T2a stage invasive bladder cancer has a certain curative effect with the advantage of preservation of bladder function and higher quality of life.
