Recent researches have shown that resectable pancreatic cancer can benefit from post-operative adjuvant chemoradiation, regardless its surgical margins, tumor size, lymph node involvement and the level of cell differentiation. Several phase Ⅱ clinical trials indicated a good tolerance to preoperative chemoradiation. Although there is no gold standard for treating locally advanced unresectable pancreatic cancer, gemcitabine-based chemotherapy or chemoradiation therapy can increase survival rate compared with best supportive care.

The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

To investigate the potential role of hepatitis B virus(HBV) preS1 protein in mediating HBV adhesion to liver cell, we prepared recombinant proteins of HBV preS1 in yeast. PCR was performed to amplify the gene of HBV preS1 from the plasmid pCP10/HBV ayw subtype containing the whole fragment of HBV and the PCR product was cloned into pGEM T vector. The gene of HBV preS1 was cut from pGEM T vector and cloned into yeast expression plasmid pGBKT7, the pGBKT7 plamids containing preSl were transformed into yeast cell AH109. The yeast protein was isolated and analyzed by sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS PAGE) and Western blotting. The results showed that the presence of HBV presl proteins in yeast cells was confirmed by Western slot analysis. the molecular weight of the expressed product was about 30000 Da. The findings indicated that HBV preS1 was successfully expressed in yeast system.

Objective There are still different news on the preemptive analgesia. We aimed to investigate the preemptive analgesic effect of rofecoxib on the tetrodotoxin-resistant (TTX-R) sodium current in dorsal root ganglion (DRG) neurons m a rat model of acute pain. Methods Seventy-five male SD rats weighing 100-140 g were randomly divided into five groups with 15 animals in each group: (A) sham operation + placebo group; (B) operation control group received placebo orally before operation; (C) preoperatine rofecoxib group received oral rofecoxib 10mg?kg-1 h before operation; (D) and (E) postoperatire, rofecoxib group Ⅰ and Ⅱ received oral rofecoxib 10mg?kg immediately (D) and 1 h (E) after operation. Acute pain was produced by an 1 cm long incision in the plantar surface of the right hindpaw through skin, fascia and muscle. Pain threshold to mechanical stimulation with von Frey filament was measured before (baseline) and 2, 6,12, 48, 96 h after operation. The animals were killed by cervical dislocation before and 24, 48, 96 h after incision. DRGs at L3.5 on the operated side were isolated and minced. DRG neurons were isolated by digestion with collagenase Ⅰ A and trypsin TTX-R Na-current density in DRG neurons were measured by using whole-cell patch clamp technique. Results There was no significant change in pain threshold to mechanical stimulation and Na-current density in DRG neurons during the experiment in group A, The withdrawal threshold to mechanical stimuli was significantly decreased after operation compared to the baseline in the four groups ( B, C, D, E). The decrease in pain threshold was significantly less in group C,D,E than that m group B at 2, 6, 12, 24, 48 h after operation and was the least in group C Current density (pA/pF) was significantly increased at 24 h and 48 h after operation compared to baseline in group B, C, D, E. The increase in current density was significantly less in group C, D, E than in group B and was the least in group C.Conclusion Rofecoxib given before operation has preemptive analgesic effect in a rat model of acute pain. Stronger inhibition of TTX-R Na-current m DRG neurons may contribute to the underlying mechanism.

Post-traumatic stress disorder ( PTSD) is an anxiety disorder that can develop following a traumatic event.Neuro-imaging techniques offer a noninvasive means to elucidate the brain circuit underlying PTSD, and may help to find effective biomarkers for diagnosis and treatment evaluation of this disorder.In this article, we review recent brain structural MRI studies in PTSD.Problems of the current research and possible directions for future research are also presented.

Liver volume can reflect the change of parenchyma volume and functional reserve of liver.Liver volumetry is commonly achieved by imaging methods such as ultrasound,CT and MRI,while CT volumetry is most commonly used in clinical practice.This article discussed the decision making among different liver volumetry methods and associated applications in hepatectomy.

Objective To investigate the factors influencing the lipid control success rate among patients with coronary heart disease (CHD).Methods Questionnaire and clinical data reviews were conducted to investigate the general information,disease characteristics and patients controlling blood lipid and by blood biochemical tests were done to detect the lipid levels.The relationships between lipid control success rate and general information,disease characteristics and patients' behaviors were analyzed by chi-square test and logistic regression analysis.Results The blood lipid success rate was only 67.09％ in patients with CHD combined dyslipidemia.The education level,cardiovascular disease risk grading,complications,body mass index,medication compliance and dietary evaluation were the main factors influencing the patients' success in blood lipid control.Conclusion The lipid control success rate can be raised by taking measurements to help patients with CHD and dyslipidemia control weight and increase medication compliance and dietary behavior.
