The prognosis of patients with pancreatic cancer is dismal, especially at the advanced stage of the disease. Surgery is considered as the only curative treatment modality for pancreatic cancer;however, less than 20% of patients are candidates for curative surgical resection. Multidisciplinary management, including radiation therapy with concurrent chemotherapy, followed by systemic chemotherapy, is the treatment of choice for locally advanced pancreatic cancer. An early phase Ⅲ clinical trial conducted by GITSG (GI Tumor Study Group) has demonstrated a survival benefit for concurrent chemoradiation as compared to radiation alone in locally advanced disease. 5-FU,capacitabine and gemcitabine are the most investigated chemotherapy agents used with radiation. Currently thecombined use of gemcitabine and radiation therapy is under active investigation, and may provide substantial clinical advantage over other regimens. Multi-agent chemotherapy regimen used in concurrence with radiation has not demonstrated any significant effect but with severe toxicities. Conformal radiotherapy should be routinely used to treat locally advanced pancreatic cancer with doses of 45-50.4 Gy. The target of locally advanced pancreatic cancer is focussed on the gross tumor with safe margins. The use of IMRT is highly recommended for unresectable tumor, and makes further dose escalation possible.

OBJECTIVE: To assess the influence of Qingdu (QD) capsule on the pharmacokinetic of HAART. METHODS: The 36 SD rats were divided into 3 groups. Rats in Group HAART were given, using an intragastric gavage needle, highly active antiretroviral therapy (HAART) containing zidovudine (AZT), 2',3'-dideoxy-3'-thiacytidine (3TC) and efavirenz (EFV). Group HAART+QD were given HAART and QD capsule simultaneously. Group HAART+QD (2 h interval) were given HAART and then given QD capsule 2 h later. Blood samples were collected at 0, 0.5, 1, 2, 3, 4, 6, 8, 10 and 12 h. AZT, 3TC, and EFV concentrations were tested with high performapce liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Pharmacokinetic parameters were compared among different groups. RESULTS: The t1/2 of AZT were statistically different among the three groups (P<0.05), Group HAART+QD (2 h interval) had the lease t1/2 of AZT than the other two groups. There were no statistical differences among groups for the AUC0-12, tmax, ρmax and CL of AZT, and all five parameters of 3TC and EFV. CONCLUSION: QU doesn't show influence on pharmacokinetic parameters of AZT+3TC+EFV regimen, but intention should be paid to individual differences.

Objective To determine if propofol-remifentanil and isoflurane have any different effects on intrapulmonary shunt during one-lung ventilation (OLV). Methods Twenty-four ASA Ⅰ or Ⅱ patients (18 male, 6 female) aged 42-69 yr undergoing radical esophagus cancer resection via left thoracotomy were randomly divided into 2 equal groups ( n = 8 each) : propofol group (Pro) and isoflurane group (Iso) . The preoperative lung function was normal in both groups. The patients were premedicated with intramuscular diazepam 10 mg and atropine 0.5 mg. Radial artery was cannulated and S-G catheter was placed via right internal jugular vein in pulmonary artery. Anesthesia was induced with propofol 1.5-2.0 mg?kg-1, fentanyl 4 ?g?kg-1 and succinylcholine 1.5 mg?kg-1 and maintained with TCI of propofol and remifentanil (target plasma concentration was set at 3.2 ?g?ml-1 and 4.5 ng?ml-1 ) or isoflurane inhalation ( end- tidal isoflurane concentration = 1.5% -2.5 % ) and intermittent i. v. boluses of fentanyl. The patients were mechanically ventilated after endobronchial intubation with double-lumen tube (VT = 8-10 ml, RR= 10-12 bpm, I:E = 1:2) . During OLV VT was reduced to 6-8 ml and RR increased to 14-16 bpm.PaCO2 was maintained at 35-45 mm Hg. ECG, HR, MAP, SpO2, auditory-evoked potential index (AAI), cardiac index (CI), airway pressure and end-tidal isoflurane concentration were continuously monitored during operation. Blood samples were taken from radial artery and pulmonary artery at 10 min after S-G catheter placement (T0, baseline) at 10 min bilateral ventilation (in right lateral position) (T1) at 15, 30, 60, 90 min of OLV (T2-5) for measurement of blood gases and calculation of Qs/Qt.Results The two groups were comparable with respect to age, M/F ratio, body weight and preoperative lung function. AAI was below 30 during operation and PaCO2 and pH were within normal range in both groups. Qs/Qt was significantly increased while PaO2 was significantly decreased during operation (from T1 to T5 ) as compared to baseline values (T0) but Qs/Qt was gradually decreasing while PaO2 was gradually increasing from T2-5 in both groups. Qs/Qt was significantly lower in Pro group than in Iso group at each interval (T2-5) but there was no significant difference in PaO2 at T2-5 between the two groups. Conclusion There is less intrapulmonary shunt during OLV under general anesthesia with propofol-remifentanil than with isoflurane but the difference is not significant enough to affect PaO2.

Objective: To evaluate the applicability, reliability and validity of the Rey-Osterrieth Complex Figure Test (CFT)in Chinese normal elderly. Methods: A total of 111 normal elderly were assessed by the CFT (Form A) and the mini-mental state examination (MMSE). Among these subjects, 40 were also administered the CFT (Form B), the Block Design and the Visual Reproduction tests. Results: No significant difference was found between CFT (Form A) and CFT (Form B) with respect to copy, delayed recall and recognition. Recall performance was related to copying strategy and level of organization. Details of accuracy and their respective placement were evaluated in both copy and delayed recall trials for CFT (Form A). Conclusion: As a measure for visual-spatial constructional ability and visual memory, the CFT (Form A & B) was assessed to be psychometrically reliable and valid to be used in normal Chinese elderly.

Objective To test the efficacy and safety of nicergoline in treatment of vascular dementia patients with mild or moderate cognitive impairment. Methods A multicenter,double blind,randomized,efficient drug controlled clinical trial was carried out All the subjects met the DSM-Ⅲ criteria for vascular dementia We used MMSE and WMS as main assessing items and ADL,CGI as secondary assessing items. Results 103 subjects were assessed MMSE were raised in both groups after the treatment and more obvious in nicergoline group than in anecetan group (1 62?2 33 and 2 88?2 85 respectively) WMS raised in nicergoline group (5 04?10 61),but not in anecetan group (1 98?9 49) ADL and CGI (SI) showed decreased scores in both groups Total efficiency of nicergoline was 80 0% and of anecetan was 56 6%. Conclusions Nicergoline was an effective drug in treatment of vascular dementia and more effective than anecetan Using nicergoline 60 mg per day was safe

In this study,we isolated and characterized chlorobenzene degrading bacteria from the effluent and sludge samples of one chemical plant.Minimal medium supplemented with chlorobenzene as sole car-bon source was used during the enrichment and domestication process.Seven major bacterial isolates were obtained and purified.Their 16S rRNA genes were amplified by PCR for sequencing and their identities were determined with homology comparisons.Five of the seven isolates belong to Actinomycetales in-cluding Kocuria KD139,Rhodococcus KD140,Rhodococcus KD142,Arthrobacter KD230,and Ar-throbacter KD232;one is classified as Bacillus d KD178;and another one as Stenotrophomonas KD237.The phylogenetic tree was also constructed based on the analysis of 16S rRNA gene sequences.Chloro-benzene concentrations were quantified with gas chromatography to investigate the bio-degradation rates of the isolated strains.Stenotrophomonas KD237 degraded 60.78% chlorobenzene in the minimal medium within 24 h.

Methamphetamine is a powerful stimulant of amphetamine type in the central nervous system (CNS),and recently it has become the major drugs of abuse.A lot of research results show that MA may induce dopaminergic neurotoxicity in the animal and human striatum.The mechanisms include effects on dopaminergic signaling and dopamine oxidation,glutamate induced excitotoxicity,oxidative stress and inflammatory cytokines,disruption of mitochondfia,apoptosis,activation of glial cells and hyperthermia.However the mechanisms by the MA-induced dopaminergic neurotoxicity are not completely understood.The paper reviewed recent progress of study on them to provide reference materials for related research.

Objective: To develop Auditory Verbal Memory Test (AVMT) suitable for Chinese elderly. Method:100 normal elderly and 22 patients with mild to moderate Alz heimer' s disease were evaluated by AVMT, mini mental state examination. 40 person randomly selected from the 100 sample were assessed in follow up by AVMT, Wechsler Memory Scale ( Chinese Revised Version), information and similaritias subtests of Wechsler Adult Intelligence Scale - Chinese Revised Version (WAIS- RC) . Results: The correlation between inter- raters was 0.99, test- retest reliability at 3 months interval were 0.87～0.94. Education was a prominent influence factor of memory and recognition of AVMT. There were significant correlation between third recall, short delayed recall and total scores of VMS- RC, between long delayed recall and verbal sceres of WAIS - RC. Semantic clustering strategy showed gradual strongly correlation with measures of recall ability in higher education group. Performance of Alzheimer group was poorer than that of matched normal control. Scores of long delayed re call differed most obviously in group comparison. Conclusion: AVMT had good reliability and validity
