Purpose To investigate the MSCT diagnosis and differential diagnosis of rare pancreatic tumors.Materials and Methods The MSCT features were analysied respectively of 31 cases with pancreatic tumors confirmed by surgery and pathology.Results There were serous cystadenoma in 7 cases,mucinous cystadenoma in 9 cases,mucinous cystadenocarcinoma in 1 case,solid-pseudopapillary tumor in 8 cases,islet cell tumor in 4 cases,carcinoid tumor in 1 case and intraductal papillary adenocarcinoma 1 case.The MSCT appearances were different each other.Conclusion MSCT is very helpful in diagnosis and differential diagnosis for the rare pancreatic tumors.

The binding capacity (R_o) and apparant dissociation constant (K_d) of glucocrticoid binding sites in hepatic cytosol of normal and scalded rats were measured by pseudoscatchard analysis. Compared with control group, the levels of Ro of glucocorticoid receptor was significantly decreased 1 h after scalding, partialy recovered at 12h after scalding and fully recovered at 24 h after scalding. The levels of low-affinity glucocorticoid binding sites were also decreased 12 h after scalding, but had no statistical significance. The possible significance of these results has been discussed.

Objective To investigate multi-slice spiral CT manifestations and its diagnostic value of extragastrointestinal stromal tumor(EGIST).Methods CT data in 19 patients with EGIST proved pathologically were retrospectively reviewed.Results Of the 19 cases,the lesions located in reteoperitoneum in 8 cases,adrenal,greater omentum,omentum and mesentery in one case respectively,mesentery in 4 cases,and abdominal cavity in 4 cases.2 cases were benign,4 cases were potential malignant,and 13 cases were malignant.The size of tumors ranged 4.1～35 cm.The tumors were round or oval in 5 cases,lobulated in 5 cases and irregular in 9 cases.The tumors in 4 cases were uniform density on plain CT scans,1 case of uniform and moderate enhancement,1 case of non-uniform enhancement,2 cases of apparent enhancement as ring on contrast-enhanced CT scans;15 cases showed unhomogeneous density,on contrast-enhanced scans,moderate or remarkable enhancement was seen in the parenchyma of the tumor,while no enhancement was revealed in the necrosis and cystic areas of the tumors.Conclusion EGIST have certain imaging characteristics and MSCT was valuable in diagnosing and differential diagnosing EGIST.

Objective:To investigate the effect and safety of sertraline tablets with oral administration in the diabetes patients com-plicated with depression. Methods:Totally 74 diabetes patients complicated with depression were randomly divided into 2 groups with 37 ones in each. All the patients were orally given dimethyldiguanide 500 mg,tid,and the observation group was given sertraline tablets additionally,50-100 mg,qd. The treatment course was 8 weeks. The changes of sugar metabolism and the scores of self-rating depres-sion scale( SDS)and quality of life scale( DMQLS)in the two groups were compared. Results:After the 8-week treatment,the blood sugar,SDS scores and DMQLS scores in the two groups were significantly improved when compared with those before the treatment( P<0. 05). The levels of FBG,2hPG and HbAlc and SDS scores in the observation group were significantly lower than those in the con-trol group(P<0. 05),while the scores of DMQLS disease,psychology,society and satisfaction dimension were significantly higher in the observation group(P<0. 05). The incidence of adverse reactions showed no statistically significant difference between the two groups(P>0. 05). Conclusion:Sertraline tablets can improve the depression of diabetes patients and enhance the blood sugar control and quality of life.

Purpose:To study the connection between the blocking of N-acetylglucosaminyltransferase V(GnT-V) and endoplasmic reticulum stress(ER stress). Methods:The recombinant plasmid expressing siRNA of GnT-V was constructed and transfected into SMMC-7721. The key molecules such as GRP78,XBP1 and PERK during ER stress was analyzed in mRNA and protein levels. Results:GRP78 mRNA and protein levels were upregulated, the spliced forms of XBP1 mRNA and protein appeared and ER eIF2? kinase PERK was activated. Conclusions:These results suggest the blocking of GnT-V in SMMC-7721 induces cellular ER stress.

Several cytokines which play key role in asthma patients with chronic inflammation and reconstruction of air duct,are important targets for anti-asthma agents.In this review,we summarize the latest advancement of anti-asthma agents which targeted for cytokines(interleukins,TNF,eotaxin)and investigation development of new anti-asthma agents emerged in recent years.

Dysregulation of cell metabolism, especially glucose metabolism, is implicated in tumorigenesis and tumor progression.Cancer cells uptake a large amount of glucose and prefer to perform glycolysis in the cytosol even under normal oxygen condition, which fuels fast cell growth and proliferation.Dysregulation of glucose metabolism leads to tumorigenesis and promotes cancer development.Conversely, the initiation and development of cancer reprograms glucose metabolism to confer cancer cells the ability to survive and proliferate.Oncogenes, tumor suppressors or non-coding RNAs could regulate glucose metabolism.Meanwhile, the enzymes and metabolites involved in glucose metabolism could regulate the expression of factors related to cancer.Enzymes, the direct executor of cell metabolism, play a key role in dysregulation of glucose metabolism, tumorigenesis and tumor development.

Objective:To observe the clinical efficacy of warm acupuncture in the treatment of diabetic peripheral neuropathy and its effects on the conduction velocity of the tibial nerve and common fibular nerve.Methods:Fifty.two subjects were evenly randomized into two groups and treated by conventional therapy;in addition,the control group was given mecobalamin injection at 500 μg,once a day for four weeks,and treatment group was given warm acupuncture,6 times a week for 4 weeks.The clinical efficacy and the conduction velocity of the tibial nerve and common fibular nerve were observed and compared between the two groups.Results:After four-week treatments.the total effective rate Was 88.5% in the treatment group and 61.5% in the control group,with a higher rate in the treatment group than in the control group (P＜0.05):the conduction velocity of tibial nerve and common fibular nerve Was higher in both groups(P＜0.05),with higher conduction velocity in the treatment group than in the control group (P＜0.05).Conclusion:Warm acupuncture is quite effective to treat diabetic peripheral neuropathy and to improve nerve velocity.
