Adenocarcinoma of exocrine pancreas is a highly malignant tumor with extremely low resectability.Radiotherapy,by inducing necrosis and apoptosis of tumor cells through irradiation effects on cellular DNA,in combination with chemotherapy,has made great contribution to multimodal treatment of this malignancy.The development of radiation therapy for pancreatic carcinoma in recent years was reviewed in neoadjuvant and adjuvant settings,and for locally advanced disease.Further evidence is required to show the impact of radiochemotherapy in the treatment of unresectable disease.

Poly(ADP-ribose) polymerase(PARP) is a protein-modifying and nucleotide-polymerizing enzyme. As a critical element in DNA repair, PARP can be activated by DNA strand breaks. Excessive activation of PARP, however, can deplete NAD + and ATP, leads to cell death. Cleavage of PARP by activated caspase-3 play an important role in cell apoptosis.

Objective　To study distribution of the calcitonin gene-related peptide-immunoreactive fibers in the cremaster arteries of the rat.Methods　The distribution of the calcitonin gene-related peptide-immunoreactive fibers in the cremaster arteries had been studied by means of ABC technique.Results　The calcitonin gene-related peptide-immunoreactive fibers were observed on all branches of cremaster arteries.The immunoreative fibers in first and second branches of the arteries exhibited the denser grains and denser mass,but in third branches,the network of the fibers was obvious.The density of the immunoreactive fibers reduced following the bifurcations of the arteries.The network of the fibers also could be found in the capillary.Conclusion　The results demonstrated that the distribution of calcitonin gene-related peptide immunoreactive fibers might be related to the physiological regulation and microcirculation of the cremaster arteries.It formed the morphological basis for experimental model of researching nerve regulation in the microcirculation.

Objective To explore the significance of Community Mental Health Service funded by the government, organised by the Health Department and participated by the Community Psychiatric Service, which consists of community case managers, policemen, community health station, doctors, nurses and family of patients.Methods 150 patients, having the tendency to cause trouble or disturbance in their psychotic episodes, were placed in a case management system, monitored and treated throughout the year, gathered statistics for their number and extent of violence every month, and scored according to Social Disability Screening Schedule (SDSS).Results After one year's monitoring and treatment, the total number of occurrence of violence 5 grade among the 150 patients decreased from 20 person-times to 0 person-times; violence 4 grade decreased from 68 person-times to 2 person-times; violence 3 grade decreased from 66 person-times to 4 person-times; violence 2 grade decreased from 258 person-times to 12 person-times; violence 1 grade decreased from 432 person-times to 24 person-times. The number of patients who lost their violent tendency increased from 0 person-times to 72 person-times.Conclusion To establish community case management systems, monitor, treatment, conduct follow-up studies and providing appropriate recovery guidance for schizophreniac patients through the Community Psychiatric Service, are the effective ways to decrease the rate of causing trouble or disturbance, reduce the patients' social disability, and facilitate the patients' recovery of social functions.

Objective:To identify the effect of ?-synuclein overexpression on mitochondrial membrane structure with atomic force microscopy. Methods:?-syn expression was mediated by AAV (adeno-associated viral vector) and Recombinant AAV/?-syn and AAV/LacZ viral particles were stereotaxically injected in the left side of rat substantia nigra (SN) for rat model of ?-synuclein overexpression. Mitochondria were isolated from rats SN of Brain. Mitochondria were analysis with JC-1 staining,atomic force microscopy and Western blot. Results:By 16 weeks post-infection of AAV-?-syn,the level of ?-syn increased about 2 times in mitochondrial fraction with Western blot and mitochondrial membrane potential (??) decreased with JC-1 staining. Furthermore,mitochondria swelling and porous like structure formed on the mitochondrial membrane with atomic force microscopy. Conclusion:The data suggested that ?-syn could accumulate in mitochondria,might form mitochondrial membrane pores and lead to ?? decreases. ?-syn might lead to mitochondrial dysfunction in Parkinson's disease.

Objective To investigate the prevalence of elevated serum alanine aminotransferase ( ALT) and ALT-related dysmetabolism and risk factors. Methods A total of 12 789 adult participated,with no hepatitis B virus infection or alcohol over-intake, received health check-up, including blood pressure measurement, blood glucose and lipid profile test, liver function evaluation and ultrasonography. The subjects were then assigned into two groups according to the serum level of ALT. Metabolic composition was compared between the two groups. Results The prevalence of elevated ALT activity was 8.69%. The waist circumstance,body mass index (BMI) ,systolic blood pressure (SBP) ,diastolic blood pressure (DBP) ,total cholesterol (TC) ,triglyceride (TG) , low-density lipoprotein cholesterol (LDL-C) , urine acid (UA) , fasting blood glucose (FBG) ,HbAlc,total bilirubin (TBIL) ,-y-glutamyltransferase (GGT) ,alkaline phos-phatase ( ALP) of the elevated ALT group were significantly higher than those of the normal ALT group. However,age and high-density lipoprotein cholesterol ( HDL-C) in the elevated ALT group were lower than those in the normal ALT group ( P < 0. 05 ) . The occurrence of overweight, obesity, hyperlipidemia, impaired fasting glucose,diabetes, increased DBP, hyperuricacidemia and fatty liver in the elevated serum ALT group was significantly more than that in the normal ALT group ( P < 0. 05 ) . Multiple logistic regression analysis demonstrated that fatty liver, DBP, BMI.TC, HbAlc were risk factors of elevated serum ALT. Conclusion Non-alcoholic fatty liver disease, lipid metabolic disorders and obesity may be the main risk factors of elevated ALT.

Objective: To observe the clinical efficacy of combining two needling manipulations, Er Long Xi Zhu (two dragons playing with a pearl) and Guo Yan Re (heat produced to reach the eyes), in treating dry eye syndrome (DES) of lung-yin deficiency pattern. Methods: Fifty-six eligible DES patients of lung-yin deficiency were randomized into an observation group and a control group, with 28 cases in each group. Same acupoints were selected in the two groups: Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20) were chosen as the major points and Feishu (BL 13) and Chize (LU 5) as the adjuvant. Er Long Xi Zhu and Guo Yan Re needling manipulations were applied in the observation group while twirling reinforcing manipulation was used in the control group. Treatment was conducted once per day in both groups, for two sets of 15 consecutive days at a 2-day interval. Changes in the symptom score, tear break-up time (BUT) and tear production were observed afterwards, and the clinical efficacy was also compared between the two groups. Results: The total effective rate was 92.8％ in the observation group, higher than 71.4％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the symptom score, tear BUT and tear production showed significant improvements in both groups (all P<0.05); the symptom score, BUT and tear production in the observation group were significantly different from those in the control group (all P<0.05). Conclusion: Given the same acupoint selection, combining Er Long Xi Zhu and Guo Yan Re needling manipulations can produce more significant clinical efficacy than twirling reinforcing manipulation in treating DES of lung-yin deficiency pattern.

Objective To investigate the expression levels of interferon -inducible genes (MNDA)in the peripheral blood mononuclear cells (PBMCs)of patients with systemic lupus erythematosus (SLE),and the relations between the gene expression levels and disease activity were explored.Methods Reverse transcription polymerase chain reaction(RT -PCR)method was used to detect the expression levels of MNDA in 30 patients with SLE and 25 controls.The associations between the expression levels of MNDA and urine protein,complement C3,C4,anti -double stranded DNA antibody and SLEDAI scores in patients with SLE were analyzed.Results (1)The expression level of MNDA mRNA in the SLE patients was significantly higher than that of the normal controls(t =6.99,P <0.01).(2)The expression level of MNDA in the urinary protein positive patients was significantly higher than that of the urinary protein negative patients (t =3.08,P <0.01),they were all significantly higher than the normal controls (t =9.32,4.87,all P <0.01).(3)The expression levels of MNDA mRNA were positively correlated with anti -double stranded DNA antibody and SLEDAI scores(r =0.534,0.508,all P <0.05),and not correlated with comple-ment C3 and C4(r =-0.472,-0.349,all P >0.05 ).Conclusion The expression levels of MNDA mRNA in patients with SLE are significantly higher than those of the normal controls.It is linked to kidney damage and disease activity,and helpful in evaluating SLE disease activity and severity.
