Thyroid cancer is the one of the most common endocrine tumors. The biological behaviors and prognoses of the thyroid cancer of different histological types remarkably differ. The highly invasive thyroid cancer responds poorly to traditional therapies. Recent research advances in the molecular mechanisms of the pathogenesis of thyroid cancer have revealed the roles of many genetic and epigenetic variations such as gene mutation, abnormal gene amplification, and abnormal gene methylation in the development of thyroid cancer, which provides new insights in the molecular diagnosis, prognosis, and target therapy of the thyroid cancer.

Hepatitis C virus (HCV) core protein is considered to be an attractive candidate for development of protective HCV vaccines. However, this protein may attenuate the induction of systemic immune responses due to its immunomodulatory properties. In this study, we constructed a HCV core gene-containing eukaryotic expression plamid pCI-C, and an in vivo-inducible prokaryotic expression plasmid pZW-C, and transformed the recombinant plasmids into an attenuated Salmonella typhimurium aroA strain SL7207. The resulting bacterial strains SL7207/pCI-C and SL7207/pZW-C were used to orally immunize BALB/c mice, and the immune responses specific to HCV core protein were assessed. Immunization with the recombinant bacteria SL7207/pCI-C led to a persistent drop in percentage of CD3 CD4 T cells, and induced a weak anti-core IgG production. Splenocytes from SL7207/pCI-C immunized mice developed a relatively weak proliferation response and inferior cytotoxic activity compared to those from the mice immunized with bacteria SL7207/pZW-C. Boost immunization with SL7207/ pCI-C yielded limited improvement in immune strength, while the boost with bacteria SL7207/pZW-C significantly enhanced the immune response. These results suggest that de novo synthesis of native HCV core protein may blunt the induction of immune responses. Attenuated S. typhimurium carrying HCV core protein could efficiently activate systemic cellular and humoral responses, and may be a promising strategy for the development of core-based HCV vaccines.

OBJECTIVETo investigate the apoptosis induction effect of vitamin E succinate (VES) on Tca8113 cells and its possible mechanisms.
METHODSThe proliferative activity of Tca8113 was assessed by methyl thiazolyl tetrazolium (MTT) assay. After Tca8113 cells were treated with different concentrations of VES, apoptotic rates were analyzed by flow cytometry (FCM). Fas monoclonal antibody was used for the blocking test. Fas expression was detected by immuocytochemistry(SABC assay) and FCM.
RESULTSVES demonstrated a significant growth inhibitory effect and apoptosis induced effect on the Tca8113 cells in a dose- and time-dependent manner. Fas neutralizing antibody can block the apoptosis induced by VES. After the administration of VES, the expression of Fas protein increased and the kytoplasm staining enhanced. Proteinum quantitative analysis showed that the mean fluorescence intensity increased.
CONCLUSIONVES can induce apoptosis in human tongue cancer cells, and the up-regulation of the cell surface Fas protein may play an important role in the process.

OBJECTIVETo study the feasibility of binding pancreatic duct to mucosa anastomosis (BDM)-a complementary procedure to both binding pancreaticojejunostomy and binding pancreaticogastrostomy.
METHODS(1) Animal experimental study:gastrostomy and jejunostomy were performed on six adult New Zealand rabbits. The gastrostomy and jejunostomy shared a same stent (rubber urethral catheter, silicone tube or plastic infusion tube). Both ends of the stent were placed in gastric and enteric cavity. Purse-string suture was performed around the stent before the jejunum and the stomach were brought together for fixation by few stitches. And to observe whether the purse-string suture around a plastic tube, rubber tube or silicon tube inserted into jejunum and/or stomach can prevent leaking out of the jejunal or gastric content to cause peritonitis. (2) Clinically 7 patients were performed with BDM anastomosis. The procedure was consisted of five steps: preparation of the pancreatic stump;preparation of the jejunum; preparation of the fixing sutures between the pancreatic stump and the jejunum; implementation of the anastomosis; lastly, fixation of the jejunum beside the pancreas stump. Post-operative periodic examination of the blood amylase and the amylase in the abdominal drainage. Pancreatic fistula was classified in to two categories: parenchymal fistula (pancreatic cut surface fistula) and anastomotic leakage.
RESULTSAnimal experiment did not show any leakage around the plastic tube or silicon tube inserted into jejunum and(or) stomach. There was no anastomotic leak in all the patients. There was transient increase of amylase in two cases, but the volume of drainage did not exceed 50 ml/d and the recovery of the patients was not affected.
CONCLUSIONSBDM is a simple, safe and easy procedure to perform. It provides to the surgeons with a new option in different situations to achieve the most ideal surgical result.

OBJECTIVETo study the effect of enteral nutrition via jejunostomy catheter on the quality of life in gastric cancer patients who have undergone gastrectomy.
METHODSWe retrospectively analyzed clinical data of 104 consecutive patients who had undergone curative resection for gastric cancer in Peking Union Medical College Hospital in 2011.All data were obtained from a prospectively maintained database of gastric cancer.The quality of life was compared between jejunostomy tube group(n=49)and tube-free group(n=55).
RESULTSThe two groups were matched in gender,age,tumor size,tumor location,histological type,pTNM stage,type of surgery,body mass index(BMI),quality of life scales,and cycles of postoperative adjuvant chemotherapy(all P>0.05).Also,the global health status(P=0.154),physical function score(P=0.321),role function score(P=0.492),and fatigue symptom score(P=0.845)were not significantly different between these two groups one month after surgery.Three and 6 months after the surgery,patients in the jejunostomy tube group had significantly higher overall health status scores( P<0.001,P=0.038),physical function scores(P=0.004,P=0.005),and role function scores(P=0.002,P=0.038)and significantly lower fatigue symptom scores(P=0.020,P=0.043)when compared to patients from tube-free group.
CONCLUSIONEnteral nutrition via jejunostomy catheter can improve the quality of life of gastric cancer patients who have undergone gastrectomy.

OBJECTIVETo study the correlation of homocysteine (Hcy) in plasma with nitric oxide synthetase (NOS) and endogenous carbon monoxide (CO) in the penile corpus cavernosum of type 2 diabetic rats.
METHODSThis study included 40 male Wistar rats, 10 as controls (Group A) and the other 30 as diabetes mellitus (DM) models. Four weeks after the model establishment, the model rats were divided into a DM group (Group B, n = 10), an insulin treated group (Group C, n = 10), and a folic acid and vitamin B12 treated group (Group D, n = 10). All the rats were injected with apomorphine and observed for penile erection at 8 and 12 weeks, and the levels of total plasma Hcy (tHcy), NOS and CO in the penile corpus cavernosum were measured at 12 weeks.
RESULTSCompared with Group A, the level of tHcy was significantly increased, while NOS and CO activities in the penile cavernous tis-sue and erectile function remarkably decreased in Group B (P < 0.01). The incidence rate of high Hcy was 55% in the DM rats. In comparison, the level of tHcy was obviously decreased, and the NOS activity and erectile function markedly increased in Groups C and D (P < 0.01). The Hcy level showed a significant negative correlation with NOS activity (rA = -0.89, rB = -0.76, rc = -0.91, rD = -0.91) and CO content (TA = -0.82, r, = -0.77, rc = -0.93, rD = -0.81).
CONCLUSIONHigh plasma Hcy can decrease NOS and CO activities in the penile corpus cavernosum, and consequently induce erectile dysfunction in DM rats, while insulin, folic acid and vitamin B12 can improve their penile erectile function by increasing NOS and CO activities.

OBJECTIVETo establish and evaluate a real-time PCR assay to detect Mycoplasma pneumoniae (M.pneumoniae) in clinical specimens.
METHODSBy analysing the whole p1 gene sequence of 60 M.pneumoniae clinical isolates in Beijing of China, an optimized real-time PCR assay (MpP1) using p1 gene conserved region was designed. The specificity and sensitivity of this assay were evaluated and compared with other two reported assays (RepMp1 and Mp181) using 40 positive and 100 negative clinical specimens.
RESULTSThe detection limit of the new assay was 8.1 fg (about 1∼3CFU) M.pneumoniae DNA. The sensitivity of MpP1, RepMp1, and Mp181 assays appeared to be 100%, 100%, and 85%, respectively.
CONCLUSIONMpP1 assay is suitable for the detection of M.pneumoniae in Chinese clinical specimens.
