Objective To study the relationship of different histological types and degrees of infiltration of gastric adenocarcinoma on lymph node metastasis.Methods The clinical data of 1 615 cases of gastric adenocarcinoma were analyzed retrospectively,and the rate and number of lymph node metastasis in different histological types and with different depths of invasion were statistically analyzed.Results There were 46 227 lymph nodes collected from 1615 cases,with an average of 28.62 per case. Lymph node metastasis was found in 1046(64.77%) cases of gastric cancer and 10 173(22.01%) lymph nodes. Different TNM stages showed different rates of metastasis: T1(M)2.78%,T1(SM)13.61%,T2 55.59%,and T3 84.84% respectively,while the metastatic rate for histolgically well-differentiated carcinoma was 50.25%,and for low-differentiated earcinoma was 78.95%,and both had statistically significant difference(P

Objective To analyze dynamic features of TCM syndrome elements according to the neuropsychological characteristics of cognitive function impairment after ischemic stroke.Methods The hospitalized cerebral infarction patients without dementia were evaluated dynamically with the mini-mental state examination (MMSE) and Montreal Cognitive Assessment (MoCA) (Beijing Version) after IQCODE screens at different phase points.And they were divided into groups according to the severity of cognitive function impairment.The occurring frequency of TCM syndrome elements at all phase points for diagnosis was compared.Results The phase points and TCM syndrome elements closely related with the cognitive function impairment after ischemic stroke were as following:the 3rd day with fire and yin deficiency,the 7th day with yin deficiency,the 1st month with fire,phlegm,and blood stasis,and the 3rd month with fire,phlegm,blood stasis,qi deficiency,and yin deficiency.Conclusion The neuropsychological characteristics of cognitive function impairment of ischemic stroke are closely related with TCM syndrome elements and their evolvement as well as their different combinations.

Objective To evaluate the effects of hydroxyethyl starch (HES) on the renal function and blood coagulation of patients with acute pancreatitis (AP). Methods 151 patients with acute pancreatits were divided into treatment group (treated with HES, n=62) and control group (treated with crystalloid solutions, n =89). The two groups were compared by retrospective analysis of the indices such as serum creatinine (Scr), blood urea nitrogen (Bun), platelet count(Plt), prothrombin time activity (PTA), international normalized ratio (INR), activated partial thromboplastin time (APTT) and fibrinogen (FIB) before and after treatment. Results Before hospitalization, there were insignificant differences in respect of Scr and Bun in the two groups respectively. But at discharge, Scr and Bun in the treatment group were significantly increased (P<0.05), while Bun was significantly decreased 24 h right after infusion of crystalloid solutions in the control group (P<0.05). There were no differences between the two groups in terms of Scr and Bun. As for indices of coagulation, APTT in the treatment group was significantly increased after infusion of HES (P<0.05). The hospital stay in the treatment group was longer than the control group (P < 0.05). Conclusions HES may adversely affect renal function and intrinsic pathway of blood coagulation of patients with AP. Renal function and blood coagulation should be monitored when using HES.

Background Gene encoding optineurin (OPTN) is a causative gene for glaucoma and amyotrophic lateral sclerosis,with a more expression in retina.Our previous study isolated OPTN-interacting proteins and identified that the gene encode the basic leucine zipper (bZIP) transcription factor neural retina leucine (NRL) zipper,a causative gene for retinitis pigmentosa,and further study demonstrated the interaction between OPTN and NRL proteins in nuclei of cultured HeLaS3 cells.Objective This study was to determine the protein binding site of OPTN necessary for NRL binding.Methods A deletion series of OPTN-expression plasmids were constructed and co-expressed with hemagglutinin (HA)-tagged NRL in HeLaS3 cells,respectively.The cytoplasmic and nuclear fractions were used to perform co-immunoprecipitate (CoIP) and Western blot with anti-tag antibodies.Results In the nuclear fractions of cells transfected with the del1 st,del2nd or del3rd plasmid,a band of coimmunoprecipitated HA-labelled NRL (HA-NRL) was detected.However,the del4th plasmid did not produce a band.The NRL band was not found in cytoplasmic fractions from transfected cells with any of the deletion plasmids or with the whole-length OPTN plasmid.Conclusions The protein binding site of OPTN necessary for NRL binding is determined.This result demonstrates the binding of Flag-OPTN and HA-NRL in HeLaS3 cells.A series of partial-deletion OPTN plasmids demonstrated that the tail region (423-577 amino acids) of OPTN was necessary for binding with NRL.

Objective We want to study the therapeutic efficiency of autologous ADMSC transplantation in myocardial infarction.And we try to find out a good way to improve the therapeutic efficiency by using the combination of gene therapy and cell therapy.Anti-apoptotic protein XIAP was selected to fight against the ischemic environment of myocardic infaction.Methods ADMSC was isolated from rat inguinal fat tissue.ADMSC was cultivated with DMEM.XIAP experession plasmid was elertco-transduced to ADMSC.The anti-apototic function of XIAP was tested by serum stavation induced apotosis.The method of ligation of the left anterior descending artery was used to prepare the Myocardial infarction model.Then rats were randomly separated into three groups to receive direct epicardial injections of normal saline,or ADMSCs cell suspension or XIAP modified ADMSCs cell suspension at five sites in central zones of myocardial infarction and border zone.Cardiac function and the infarct size were evaluated 4 weeks after ADMSCs transplantation.Results West blotting suggest that,XIAP over-expression block serum starvation induced apotosis.It showed that there are significant statistic difference among XIAP modified ADMSC transplantation group,ADMSC transplantation group and control group 4 weeks after myocardial infarction (P ＜ 0.05).Left ventricular ejection fraction(LVEF) showed a significant improvement in ADMSCs transplantation group compared to control group (P ＜0.05).Left ventricular end systolic diameter(LVDs) and left ventricular end diastolic diameter(LVDd) of ADMSCs group were smaller than control group(P ＜ 0.05).The area of myocardial infarction was significantly reduced in the ADMSCs transplantation group compared to the saline group(P ＜0.05).Compared to ADMSCs transplantation group,effect of the XIAP modified ADMSC in rats with myocardial infarction is more obvious.The reduction of LVEF of XIAP modified ADMSCs group was signific antly lower(9％) than the ADMSCs group(16％) (P ＜ 0.01).Infarction area in XIAP modified ADMSCs group(3.26 ±0.95)％ was smaller than ADMSCs group(5.17 ±2.03)％ (P ＜0.05).Conclusion Autologus ADMSC transplantation is an efficient therapeutic tool in myocardial infarction therapy.Over expression of XIAP can partly inhibit lowserum induced apotosis of ADMSC in vitro,and it can improve left ventricular function better in vivo.Over expression XIAP of ADMSC can improve the therapeutic efficiency compare to ADMSC transplantation.

The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO(2) were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P<0.05), but the level of serum albumin was significantly increased (P<0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P<0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P<0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.
