Twenty four hours after occluding of the middle cerebral artery in rats, thecirculating neutrophils were in activated state and the lipidperoxidation increased in ische-mic brain tissue. Tanshinone inhibited the chemoluminescence of the circulating neutrophilphagocytosis and decreased leukocyte infiltration in infarcted brain tissue. It alsodecreased lipoperoxide, malondialdehyde and increased SOD activity in ischemic cerebralregion. In addition, it reduced cerebral infarction size in the model. The correlationbetween inhibitory effects on leukocyte and reduction in ischemic cerebral damage wassignificant. Dexamethasone used as a positive control had similar effects on neutrophils andischemic cerebral injury. It was shown that the prophylactic effcts of Tanshinone oncerebral infarction might be mainly due to its inhibition on leukocyte function.

Objective The incidence of pancreatic cancer is increasing worldwide, and also in china. The characteristics of the cancer are: short course, rapid progress and high mortality, with median survival time of about 6 months. Unfortunately, the early symptoms of patients are not peculiarity. There are not simple, direct and effective methods of early diagnosis. When the patients have jaundice and abdominal pain, probably they are the advanced disease (stage Ⅲ-Ⅳ) ,with unresectable tumours,and have to perform biliary bypass operation for alleviative treatment. Furthermore, the most of all patients exhibit advanced disease, which is often associated with a reduced performance status, malnourished condition, immune function deficiency, all of which severely limit patients tolerance for toxic chemotherapy regimens. These may result in physiological problems that can alter the metabolism and distribution of cytotoxic drugs and therefor lead to an increase in treatment-related toxicity. Purpose To explore the effect of TPN in the post-palliative operations, Roux-en-Ycholedceho-jejunostomy, of advaneed pancreatic carcinoma patients receiving chemotherapy. Methods From Jan. 1996 to Jan. 1999, 40 cases had receiving combination chemotherapy after palliative operations for relief of jaundice by biliary hypass, and surgical biopsy for histologically cemented. The patients were randomly divided inter 2 groups: (1) treatment group (chemotherapy + TPN), 12 men and 8 women had a median age of 57.8 years old. (2) Control group (chemotherapy + routine treatment), 13 men and 7 women had a median age of 58.2 years old. All the patients received combined chemotherapy, the regimen was 5-Fu+ CF + MMC + DDP/EPI (5-fluorouracil + Calcium folniate + Mitomycin C + Cisplatin or Epirubicin ) or IFN-γ (interferon-γ). Dosages of drugs were modified for bone marrow toxicity, stomatits and declining performance status. After 28 days, the regimen performed once again. The regimen of TPN was: total caloric value (NPC) 20 Kcal/kg·d, nitrogen 0.2kg/kg·d, N/Q = 1g: 125Kcal, Glucose/Fat=6:4. The nutritional & immunological parameters, quality of life, effects of treatment wrer monitored. Results Treatemnt group is superior to control group. After TPN, serum pre. albumin, transferrin concentration, retinol-binding protein, total lymphocyte count, natural killer cells activity, IL-2R+ cells (CD25) percentage of peripheral blood, grades of quality of life and survival time increased significantly (P<0.05, P<0.01 respectively). However, no significant difference was observed in IFN-γ application group (P>0.05). Conelusions The nutritional support can improve nutritional and immune situation and quality of life, and prolong the survival time of the patients, but no relapse-free survival.

Metastasis to liver is the most happened distant metastasis and is the leading cause of death in patients with colorectal cancer.Complete surgical resection of liver metastases from colorectal cancer is major curative method for resectable metasrases.Other methods such as chemotherapy, targeted therapy, hepatic ar-tery intervention, radiotherapy, radiofrequenly ablation or cryo-ablation should be considered.Both systemic and local treatment are.important for liver metastasis from colorectal cancer.

18F-2-fluro-D-deoxy-glucose (18F-FDG) is used by positron emission tomography/computed tomography (PET/CT) examination as an imaging agent,by observing the uptake of the agent of the lesion to determine its metabolism,and make a diagnosis.It can provide anatomical and functional at the same time,not only qualitative but also position and can significantly improve the accuracy of diagnosis.Currently PET/CT has been widely used in the clinical aspects of the differential diagnosis of benign and malignant tumors,prognostic assessment and so on.The property of pleural effusion is important to the treatment and prognosis of the disease.

Objective:To study the chemical constituents in the seed of Cassia leschenaultiana.Methods: The compounds were separated and purified by column chromatography , thin-layer chromatography and recrystallization .The structures were identified by the physicoche mical identification and spectral analysis .Results:Seven compounds were isolated from the seeds of Cassia leschenaultiana and identified as 1-desmethylchryso-obtusin (Ⅰ) , aurantio-obtusin (Ⅱ) , ale-emodin (Ⅲ) , obtusin (Ⅳ) , chryso-obtusin (Ⅴ) , ob-tusifoline(Ⅵ)and aurantio-obtusin(Ⅶ).Conclusion:All of the compounds are isolated from the seeds of Cassia leschenaultiana for the first time.

Objective:To establish the HPLC fingerprint of Cassia leschenaultiana from different regions. Methods: The column was SinoChrom ODS-BP (250 mm × 4. 6 mm, 5 μm). The mobile phase consisted of acetonitrile-0. 1% phosphoric acid with gradient elution. The flow rate was 1. 0 ml·min-1 , the detection wavelength was 285 nm, the column temperature was 25℃, and the injection volume was 10 μl. Results: The fingerprint consisted of 13 common peaks. The range of similarity for ten batches of Cassia le-schenaultiana was 0. 839-0. 998. And the reference fingerprint of Cassia leschenaultiana was established by HPLC. Conclusion: The fingerprint method is simple and reproducible, which can provide basis for the quality control and the medicinal resources exploration.

OBJECTIVE To study the level of plasma fibrinogen in patients with common facial paralysis, and investigate the relationship between the plasma fibrinogen and the pathogenesis of facial paralysis.METHODS A total of 157 inpatients with different kinds of facial paralysis were studied from December 2006 to December 2008.They were etiologically divided into five groups:severe Bell's palsy group(60 cases), moderate Bell's palsy group(19 cases), Ramsay-Hunt syndrome group(28 cases), temporal bone fracture with facial palsy(28 cases), and facial nerve tumor group(22 cases).They were tested for plasma fibrinogen level right after admitted to hospital.RESULTS Plasma fibrinogen level in severe Bell's palsy group was(4.08?0.90)g/L, which was significantly higher than that in other groups and the normal value(2.0～4.0)g/L(P

400?109/L and anemia was defined as Hb

To examine the protective action and therapeutic effect of anisodamine on acute lung injure and its molecular mechanism,63 rats were randomly divided into three groups :normal control group(NS),lipopolysaccharide (LPS) group and anisodamine (ADM) group.Rat model of acute lung injure(ALI) was produced by injecting LPS(5mg/kg) into the tail vein.The lung index(LI),WBC count,the percentage of polymorphonuclear leukocyte(PMN) in the bronchoalveolar lavage fluid(BALF) were observed at 0,1,3,5 hours(T 0,T 1,T 2,T 3).The concentration of TNF-? were measured both in BALF and plasma at four time points.The expression of P65 was analyzed by immunohistochmical method five hours after injecting LPS.The results showed that LI of ADM group were significantly lower than that of LPS group at T 2 after injecting LPS(P

OBJECTIVE To compare the BacT/Alert FN with Botai SN anaerobic blood culture bottles for detection of commonly encountered anaerobes.METHODS Using these two types of anaerobic bottles to culture 5 commonly encountered anaerobes in automatic blood culturing system and BacT/Alert system,and then to analyze the results.RESULTS There were all 32 anaerobic bottles reported positive results by BacT/Alert FN bottles,and only 8 positive bottles were reported by Botai SN bottles.CONCLUSIONS The performance of the BacT/Alert FN is much better than Botai SN anaerobic blood culturing bottle when it is used to detect commonly encountered anaerobes.
