The incidence of pancreatic cancer is gradually increasing worldwide. The overall 5-year survival rate of pancreatic cancer is about 5%, because the early diagnosis is difficult and the radical resection rate is low in pancreatic cancer. The keys of improving the poor prognosis of pancreatic cancer are early diagnosis and radical resection. Detection of serum tumor markers has an important utility in the diagnosis, prognosis and surveillance of pancreatic cancer. CA19-9 is the most widely used and best validated serum tumor marker for pancreatic cancer although it has some limits. With the development of molecular biological techniques in recent years, several potential serum tumor markers for pancreatic cancer are undergoing evaltation, including MIC- 1, M2- PK, OPN, RCAS1, and so on. This paper is to review the current status of serum tumor markers of pancreatic cancer.

OBJECTIVE:To observe clinical efficacy and safety of Brucea javanica oil combined with gemcitabine and cisplat-in in the treatment of advanced non small cell lung cancer(NSCLC). METHODS:Totally 131 advanced NSCLC patients selected from Huanggang Hospital of TCM during Feb. 2014 to Jan. 2016 were divided into observation group(71 cases)and control group (60 cases)according to random number table. Control group was given Gemcitabine for injection(1st and 8th day)+Cisplatin injec-tion (2nd day),every 21 days,twice as a treatment course. Observation group was additionally given Breucea javanica oil oral emulsion 20 mL,po,2-3 times/d,for consecutive 14 d (3 days before chemotherapy). Both groups received treatment for 87 d and followed up until Jul. 1,2016. Clinical efficacy,the levels of T cell subsets (CD3+,CD4+,CD8+),survival time were ob-served in 2 groups. Single factor and multiple factor analysis was conducted for survival time. The occurrence of ADR was record-ed. RESULTS:The total response rate of observation group (32.39%) was higher than that of control group (25.00%),without statistical significance(P>0.05). Before treatment,there was no statistical significance in the levels of CD3+,CD4+ and CD8+ be-tween 2 groups(P>0.05). After treatment,the levels of CD3+ and CD4+ in observation group were increased significantly,while CD8+ level was decreased significantly;there was statistical significance compared to control group at corresponding period (P<0.05). Four patients withdrew from the study in observation group and 3 patients in control group. The survival time of observation group [(14.02 ± 4.10) months] was longer than control group [(13.21 ± 5.22) months],without statistical significance (P>0.05). Single factor analysis showed that the survival time of patients aged <70 were significantly longer than those of patients aged ≥70;those of patients with pleural effusion were significantly shorter than those of patients without pleural effusion;there was statis-tical significance (P<0.05). Multiple factor analysis showed that with or without pleural effusion,age were influential fac-tors for survival time of patients with advanced NSCLC(OR=1.685 and 0.647,P=0.012 and 0.043). There was no statistical significance in the incidence of ADR between observation group (50.70%) and control group (53.33%)(P>0.05). CONCLU-SIONS:Brucea javanica oil combined with gemcitabine and cisplatin in the treatment of advanced NSCLC patients,although not significantly improve the therapeutic effect,but can significantly improve the cellular immune function. With or without pleural effu-sion and age are infuential facters for survival time of advanced NSCLC patients.

The endophytic microorganisms found widely in many kinds of plants mediate various effects to theirs hosts. In this study, seven different dominant endophytes (SDE01 to 07) isolated from a Hy-peraccumulator-Solanum nigrum L. were resistant to Cd2+, and the strain SDE06 survived even in the medium containing 80 mg/L of Cd2+. Bacteria strain SDE06 was identified as Bacillus sp.. The removal of Cd2+ of SDE06 in different conditions were studied. Under the optimal conditions, the incubating time was 36 h, the solution pH 6.0, the temperature was 37?C and the Cd2+ concentration of medium was 20 mg/L, the highest removal rate was up to 80.2% at this condition.

Objective To study the effect of antiapoptosis factors PED/PEA-15 and XIAP on prostate cancer cells(PC-3)apoptosis.Methods The expressions of XIAP and PED/PEA-15 in prostate cancer cells(PC-3)were respectively assayed using the RT-PCR technique.XIAP and PED/ PEA-15 specific siRNA vectors were designed and constructed and then were transiently cotransfected into PC-3 cells under induction of liposome.The effects of siRNA vectors on PED/PEA-15 and XIAP transcription were assayed by RT-PCR technique,and the effect of XIAP and PED/PEA-15 on cancer cell apoptosis were determined by flow cytometry and microscope observation.Results PED/PEA- 15 and XIAP were both highly expressed in PC-3 cells.Enzyme digestion analysis and DNA sequencing confirmed that the PED/PEA-15 and XIAP-specific siRNA expression vectors were constructed successfully.The designed siRNA sequences of PED/PEA-15 and XIAP could specifically inhibit their transcription.The PC-3 cells which were cotransfected with PED/PEA-15 and XIAP- specific siRNA vectors were more sensitive to doxorubicin.The apoptosis rate of cotransfected cells was significantly increased.Conclusions PED/PEA-15 and XIAP might be involved in the development of prostate cancer.

AIM To establish an HPLC-ELSD method for the simultaneous content determination of gastrodin,parishin A,parishin B,ginsenosides Rg1,Re,Rf,Rb1 and Rd in Tiantai No.1 Tablets (Ginseng Radix et Rhizoma,Gastrodiae Rhizoma,Cistanches Herba,etc.).METHODS The analysis of methanol extract of this drug was performed on a 45 ℃C thermostatic Alltima C1scolumn (4.6 mm × 250 mm,5 μm),with the mobile phase comprising of acetonitrie-0.1％ phosphoric acid flowing at 1.0 mL/min in a gradient elution manner.RESULTS Eight constituents showed good linear relationships within their own ranges (r ＞ 0.999 0),whose average recoveries were 96.94％-97.93％ with the RSDs of 1.06％-2.48％.CONCLUSION This simple,accurate and reliable method can be used for the quality control of Tiantai No.1 Tablets.

Objective To evaluate the difference of internal diameter of bronchial artery in big lung cancer,small lung cancer,and normal lung with multiple slice CT.Methods MSCT angiographies of 44 patients with lung cancer confirmed by pathology were retrospectively analyzed,and 29 patients were with big lung cancer(≥3 cm)and 15 patients with small lung cancer(

OBJECTIVE To explore the clinical effect of tonsil temperature-controlled bipolar radiofrequency ablation technology in the treatment of snoring and mild-moderate-obstructive sleep apnea hyponea syndrome(OSAHS). METHODS Forty-six patients were selected,of which 17 were snoring and 29 were mild-moderate-obstructive sleep apnea-hyponea syndrome cases. Tonsil temperature-controlled bipolar radiofrequency with varying probes was used for all patients. RESULTS A follow-up of 6～18 months was carried out. 9 of 17 snoring cases resulted in recovery. The procedure was effective in 6 cases and not effective in 2 cases. 15 of 29 OSAHS cases resulted in recovery. The procedure was effective in 10 cases and not effective in 4 cases. Overall successful rate was 86.9 %(40/46). The size of tonsils, apnea hyponea index(AHI),snoring scale and Epworth sleepiness score(ESS)were significantly decrease dafter operation(P

AIM:To investigate the effect of compound of cordyceps sinensis(CS) and tripterygium hypoglaucum on survival time of the heterologous human-pig graft skin.METHODS: CS solution were used to hatch the skin graft and CS was used locally.Ciclosporin A(CsA) and normal saline solution(NS) were used in control.Besides,skin HE staining was detected and CD4,CD8,IL-2 and IL-10 were also examined before and after operation.RESULTS: The survival time of the graft skin treated with CS was(21.20?3.19) days,while the control group treated with NS was(10.17?1.94) days(P
