AIM: To observe acute coronary syndrome (ACS), including acute myocardial infarction (AMI), and unstable angina pectoris (UAP) and plasma monocyte chemoattractant protein-1 (MCP-1) in patients with restenosis after angioplasty, and compared with normal controls. METHODS: Sixty-eight patients were selected from the Department of Cardiology, Third Hospital Affiliated to Peking University between December 2005 and April 2006, including 30 patients with AMI, 20 patients with UAP and 16 patients with restenosis after angioplasty. Thirty healthy people were selected simultaneously to be the controls. All subjects knew and agreed with the items. The level of blood lipid was determined in all enrolled subjects: ① Blood sample was obtained from the elbow of patients with AMI immediately at hospitalization (2-12 hours from onset). ② Blood sample was obtained from patients of UAP group and patients of restenosis after angioplasty group immediately after the hospitalization (within 24 hours of onset). ③ Blood sample was obtained from fasting subjects of the normal control group in the morning. Blood sample was centrifuged, separated of the plasma and then frozen at -70 ℃. The level of plasma MCP-1 was determined with ELISA for statistical analysis. RESULTS: A total of 98 enrolled subjects were involved in the analysis of results, and no one withdrew from the study. Comparison in plasma MCP-1 among all groups: The plasma MCP-1 in ACS group, UAP group and restenosis after angioplasty group were (166.7?46.5,149.4?54.9,119.7?25.0,89.2?26.4) ng/L respectively, and it was significantly higher in ACS group, UAP group and restenosis after angioplasty group than that in the normal control group (F =21.27,P

Aim To investigate the effect of Dicranostiga Leptodu (Maxim) Fedde (DLF) on experimental liver injury induced by Calmette Guerin bacillus vaccine (BCG) and Lipopolysaccharide (LPS) in mice. Methods Experimental liver injury was induced by Calmette Guerin bacillus vaccine and Lipopolysaccharide in male mice by injecting via tail vein (50 ?g?kg -1 ), and administering LPS (10 ?g?mouse -1 ) 10 d later. Therapeutic groups were given respectively with DLF (0 5,1 0,2 0 g?kg -1 ) before administration of LPS. The level of ALT, AST and LDH and the concentration of ALB and GLB in serum were measured by automatic biochemistry analyzer, and MDA in liver plasma was measured by TBA method and the level of SOD was measured by pyrogallol auto oxidation method. Pathological morphological changes in liver tissue were observed. Results The three experimental groups were found with significant decrease in the elevation of serum GPT and LDH level and the content of MDA in the liver plasma. The liver tissue damages were also ameliorated. Conclusion DLF has protective effect against the experimental liver injury induced by BCG and LPS in mice.

Objective To investigate the epidemic characteristics and trends of incidence and mortality of prostate cancer in cancer registration areas in Zhejiang province from 2000 to 2009.Methods Clinical data incidence and mortality of prostate cancer were collected from 6 cancer registration areas in Zhejiang province,including Hangzhou,Jiaxing,Jiashan,Haining,Shangyu and Xianju.Crude rates,standardized rate and change trend,age-specific rates and annual percent change (APC,95％ CI) of prostate cancer were checked,sorted and analyzed in Zhejiang Cancer Center.Results The prostate cancer incidence rate from 2000 to 2009 was 9.79/100 000,age-standardized incidence rates by world standard population (ASIRW) was 6.39/100 000,and the incidence cumulative risk of males aged 0-74 was 0.72％ ; while the mortality rate was 2.73/100 000,age-standardized mortality rates by world standard population was 1.74/100 000,and the mortality cumulative risk of males aged 0-74 was 0.14％.Age-specific incidence of prostate cancer remained low before 50,years old and peaked at over 85-year-old group (130.30/100 000).Age-specific mortality of prostate cancer increased after 55,and also peaked at over 85-year-old group (81.19/100 000).The annual prostate cancer incidence rate generally grew from 1.39/100 000 (2000) to 13.89/100 000 (2009),and the APC was 14.18％ (95％ CI,9.68％-18.98％).Meanwhile,the prostate cancer mortality rate also increased from 1.52/100 000 (2000) to 3.58/100 000 (2009),and the APC was 11.83％ (95％ CI,5.69％-18.33％).Conclusion Prostate cancer incidence and mortality in Zhejiang cancer registration areas increased sharply,and the prevention and treatment of prostate cancer should be strengthened.

BACKGROUND:The laser applied in the clinical oral medicine is mainly for early diagnosis of caries, removal of carious tissue, pulpotomy for pulp bleeding, dentin hypersensitivity treatment, disinfection of infected root canals, and periodontitis treatment. OBJECTIVE:To explore the changes of basic fibroblast growth factor in inflammatory pulp after laser treatment. METHODS:Five healthy adult beagle dogs were enroled, and six teeth were randomly selected from each dog. Then, these teeth were randomly divided into three groups, 10 teeth in a group, and they were treated with laser irradiation, saline and gentamicin irrigation respectively. At days 1, 2, 3 after operation, exudates from the pulp were colected for detection of basic fibroblast growth factor expression. Meanwhile, the dental pulp was detected by hematoxylin-eosin staining and immunohistochemistry method. RESULTS AND CONCLUSION:In the al three groups, the expression of basic fibroblast growth factor at day 3 was significantly higher than that at days 1 and 2, and there were no differences between days 1 and 2. Moreover, these three groups also showed no significant differences. Under hematoxylin-eosin and immunohistochemical staining, blood vessels in the pulp cavity were in good condition and the pulp arranged tightly. These findings suggest that the laser is safe, convenient and effective for oral clinical application, and has no injury to the inflammatory pulp.

Objective To explore the effect of team resource management mode in reducing the door-to-needle time (DNT) of acute ischemic stroke. Methods A total of 272 acute ischemic stroke patients admitted to our hospital from January to December 2014 were set as the observation group. The observation group adopted the team resource management mode which was composed of emergency triage nurses, thrombolysis group nurses, emergency CT nurses, emergency intensive care nurses, interventional radiology nurses, cerebrovascular medicine nurses and rehabilitation medicine nurses. Another 264 acute ischemic stroke patients admitted to our hospital from January to December 2013 were named as the control group who was given traditional emergency treatment mode. The DNT, the activities of daily living and the nursing service satisfaction of patients were compared between the observation group and the control group. Results The DNT, Barthel index and the nursing service satisfaction of patients in the observation group were (44.93 ±11.47) min, 65.26 ±21.36, 93.39% (240/257), which were better than those of the control group, (111.99±11.10) min, 39.53±20.56, 80.41%(197/245), the differences were significant (t=115.516, 14.559, χ2=18.740, P < 0.01). Conclusions The team resource management mode is an effective tool to shorten the DNT, promote the recovery of patients and improve the quality of patients′life.
