Objective To observe the influence of pravastatin to the CRP in patients with Unstable angina Pectoris。Methods 56 cases with unstable angina pectoris were randomly divided into two groups, contrast group and experimental group. The contrast group had a normal treatment.Besides a normal treatment,the experimental group took 10mg CRP after supper per day. The course lasted for 4 weeds.Levels of CRP and blood fat were checked before and after the treatment.Results In light of significant differences compared with the contrast group, the level of CRP were apparently reduced after the therapy, Yet the level of blood fat had no notable changes.Conclusions Pravastatin can reduce the levels of CRP evidently, and has the effect of anti-inflammation,Which is independent of the function of blood fat reduction.

P～ 27 gene that has been found in recent years can inhibit cancer.It codes P～ 27 protein named CDKI.CDKI plays an important role in regulating the cell cycle.The symptom of carcinoma of the pancreas in early stage isn't distinctiveness.Once it is found,it has been in later stage.To explore the biological meaning of P～ 27kipl and carcinoma of the pancreas,we measure the expression of P～ 27kipl protein in carcinoma of the pancreas and normal pancreas tissue by using the method of immune tissue chemistry SP.

Some transport systems are foun d both in intestine and kidney with functional and morphological similarities, suc h as peptide transport system, organic anion transport system, organic cation tr ansport system, and P-glycoprotein-mediated transport system. All these transp ort systems participate in the transporting process of ?-lactam antibiotics in different extent. It suggests that inhibitors of renal transport may also affec t the drug absorption of the intestine.

AIM:To study the sedation, diuresis and anticoagulation effects of Ji-Ming-San (JMS) in animal models for exploring the circadian variations of the dosing action and verifying the rationality of administering JMS on special time. METHODS: The sedation effect and circadian difference were determined by observing the time session of ambulation, raising double-forefoot test and autonomic activity of model mice. The diuretic effect and the circadian variation in rats were examined by metabolic cage test while the anticoagulation and the circadian change were observed by glass test. RESULTS: JMS produced significant sedation effect by reducing time session of ambulation, raising upper limbs frequencies/time and autonomic activity and the built-in rhythm with autonomic activity disappeared after JMS administration. JMS had satisfactory diuretic effect and total urinary output in water-loaded rats was increased after dosing. The diuretic effect of dosing showed a circadian rhythm with more significant output during the night than that during the daytime. Also, JMS prolonged the clotting time significantly and the action exhibited circadian difference. As compared with administration at the night, the clotting time was more prolonged at the daytime. CONCLUSION: JMS can produce obvious sedation, diuresis and anticoagulation effects with varied circadian rhythm. The findings suggest that the effect of administering JMS is better at the end of rest phase than other time session.

AIM:To observe effects of Jiming Powder(Semen arecae,Pericarpium citri reticulatae,Fructus Chaenomelis,Fructus Evodiae,Folium Perillae,Radix Platycodonis,and Rhizoma Zingiberis recens) on anticoagulation and hemorheology and on the circadian variations in order to verify the rational practice of timing administering the drug by our ancestors. METHODS:The effect of Jiming Powder on clotting time(CT) was observed by using glass-tube method in mice. Quick test was used to determine the prothrombin time(PT) and circadian variations in rats. The experimental animal models of blood stasis syndrome were prepared by subcutaneous injection of adrenaline in combination with ice water bath for observing the effect of Jiming Powder on hemorheology in such types of animals,and the maximum rate of platelet aggregation was determined by method of Born turbidimetry. RESULTS:Jiming Powder could significantly delay CT and PT characteristic of circadian rhythm. As compared with the administration at daytime,CT and PT were greatly prolonged during the night. Besides,the hemorheological parameters were improved markedly in blood,plasma and fibrinogen viscosity,which suggested that the drug administration was more effective during the night than daytime. Also,the findings showed that Jiming Powder could prevent platelet aggregation induced by adenosine diphosphate. CONCLUSION:Jiming Powder plays a role in anticoagulation and improves the indication of hemorhelogy in the blood-stasis rats model,showing dosing time-dependent.

Objective:To approach the role of lymphangiogenesis in oral squamous cell carcinoma(OSCC). Methods: Immunohistochemical double staining technique was utilized to distinguish lymphatic vessels from blood vessels. MLVD was determined by manual counting to analyze the relationship with lymph node metastasis. Results: MLVD was significantly higher in 40 OSCC than 14 normal mucosa(P<0.01). MLVD in OSCC showed a statistically significant relationship with regional lymph node metastasis, depth of invasion(P<0.01). Conclusion: Lymphangiogenesis might occur in growth, infiltration and metastasis of OSCC. Detection of MLVD in OSCC might be important to evaluate tumor metastasis and judge prognosis.

Objective Studying information disclosure at China' s public hospitals and recommending on information disclosure policies.Methods Collecting and analyzing the websites of 80 public hospitals in five main Chinese cities (Beijing,Shanghai,etc.).Results Information disclosure by these hospitals is found to be identical,with a slight difference in information publicity.By percentage,the information disclosure of hospital profile,department navigation,specialists characteristics,hospital news,health education,and doctor-seeking guidance,is 100.0％,98.3％,95.0％,93.3％,90.0％and 88.3％respectively.The disclosure is found to be lack of general planning,objectivity,timeliness and sufficiency.ConclusionEstablishing the information disclosure system based on mandatory information disclosure,stipulating the content,approach and timing for public hospitals information disclosure.

AIM: To investigate pharmacokinetics of salvia miltiorrhiza injection in rats. METHODS: A dose of salvia miltiorrhiza injection (standardized as Dhpl 40 mg?kg -1 , iv) was given in rats and plasma Dhpl concentrations were determined by a HPLC method. The 3p87 software was used to calculate the pharmacokinetic parameters of Dhpl. RESULTS: The main parameters were as follows: T 1/2? = 0.29 ? 0.23 h, T 1/2? = 1.75 ? 0.99 h, V d= 0.83 ? 0.70 L?kg -1 , Cl= 0.33 ? 0.16 L?h -1 ?kg -1 , and AUC (0-inf) =149?66 mg?h?L -1 . CONCLUSION: Data of the blood concentration time of salvia miltiorrhiza injection can be fitted to a two compartment open model.

Objective To investigate the effects of ketamine on endotexin-induced production of proinflammatory cytokines(IL-6, TNF-?) and activation of their medulating factor NF-?B in vivo. Methods Forty adult male SD rats weighing 200-250 g were randomly divided into 4 groups: (Ⅰ)control group(n=10); (Ⅱ) endotoxin group received intravenous endotoxin(Escherichia coli O111: B4, Sigma) 5 mg?kg~(-1)(n=10); (Ⅲ, Ⅳ)endotexin+ketamine group received ketamine or 5 or 10mg?kg~(-1)?h~(-1) after endotoxin(n=10). The animals were anesthetized with urethane i.p. (1g?kg~(-1)). Carotid artery was cannulated for BP and HR monitoring and jugular vein was cannulated for fluid or drug administration. Two hours after endotoxin administration the animals were sacrificed by exsanguination. Blood was collected and peripheral blood monocytes(PBMC) were isolated. NF-?B activity in PBMC was measured by EMSA and plasma TNF-? and IL-6 levels were determined by ELISA. Results Progressive hypotension and tachycardia developed after endotoxin administration. Endotexin also increased NF-?B activity in PBMCs and plasma TNF-? and IL-6. Ketamine 10 mg?kg~(-1) attenuated the endotexin-induced hemedynamie levels. Ketamine(5, 50 mg?kg~(-1)?h~(-1)) suppressed NF-?B activity in PBMC and inhihited plasma TNF-? level but plasma IL-6 level was not affected. Conclusion Ketamine can suppress endotoxin-induced NF-?appa B activation. Subanesthetic dose of ketamine has anti-inflammatory action.
