Objective　To evalute long-term effect of combined therapy (radical or palliative resection of carcer and intraperitoneal hyperthermic perfusion (IPHP) chemotherapy) for advenced garstric cancer (GC) from October 1987 to October 1997 in our haspital. The cases were randomly divided into two groups: IPHP group (37 cases) and control group (34 cases). In IPHP group, before suture the abdomine, heated 5-Fu solution in abdominal cavity should be maintained at 42～43℃ for 60 minutes. Results　After IPHP chemotherapy, 12 patients with cancer cells widespreading in abdominal carity, refractable ascites were disappeared. All the patients were dischargd after IPHP. The 5-year survival rate in IPHP group (51.6%) was significanfly highter than that in control group (32.3%) (P<0.05).

Objective To investigate the clinical value of contrast-enhanced ultrasound (CEUS) in the diagnosis of postoperative complications after pancreas transplantation.Methods Eighty-six post pancreastransplantation patients were examined by CEUS to observe the perfusion of contrast agent,plot timeintensity curve (TIC),and compare to the results of enhanced CT,MRI and pathology.Results Eleven cases of thrombosis,13 cases of rejection and 13 cases of pancreatitis were observed among 86 patients.Result from CEUS showed that:① Distribution of normal pancreatic grafts vascular and parenchyma was even,TIC follows positive skewed distribution.②Thrombosis:there was no perfusion in the embolic vessels and no enhancement or low uneven enhancement in the parenchyma.③ Rejection:perfusion of the parenchyma was slow,peak value was decreased,rising and falling slope of the TIC was reduced with blunt peak.④Pancreatitis:perfusion of the parenchyma was uneven,the regional low enhanced area was visible,clear of the contrast agent was relatively slow,rising slope of TIC was reduced and the peak value was decreased.Conclusions CEUS can monitor the perfusion of the pancreatic grafts vascular and parenchyma,and get useful perfusion parameters.It has been proven as an effective method to definitely diagnose postoperative complications after pancreas transplantation.

Background and purpose:Patients with colorectal cancer are often accompanied by the increase of plasma ifbrinogen concentration. This study aimed to investigate the distribution characteristics of beta-ifbrinogen gene-448G/A, -148C/T, -1420G/A and -854G/A polymorphism and plasma ifbrinogen (Fg) concentration in patients with colorectal cancer. Furthermore, we analyzed their effects on the occurrence and development of cancer.Methods:The level of plasma Fg was quantiifed by using Clauss clotting method.FGBβ gene polymorphisms were identiifed by re-al-time lfuorescence quantitative PCR (RTFQ-PCR) in 194 colorectal cancer patients and 74 healthy controls.Results:The plasma Fg levels in tumor metastasis group and non-metastasis group were signiifcantly higher than that in control group, respectively (P<0.05). Compared with control group, the frequencies of -148T allele and mutation genotype were notably higher in disease group (P<0.05). In all the groups, the plasma Fg levels of those with -148T allele were higher than those without -148T allele (P<0.05). In stageⅣ patients, there was no difference in PFS between -148T wild gen-otype group and mutation genotype group (P>0.05).Conclusion:Plasma Fg concentration in patients with colorectal cancer was signiifcantly raised, which suggests that Fg may play a role in the occurrence and development of colorectal cancer. The beta-ifbrinogen gene -148C/T polymorphism is one of the reasons that cause plasma Fg elevation, but has no correlation with prognosis of patients with stageⅣ colorectal cancer.

This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.

Objective To investigate the clinical characteristics of purulent meningitis caused by streptococcus pneumoniae.Methods We studied clinical features of 12 children with purulent meningitis caused by streptococcus pneumoniae who were hospitalized from Jan 2007 to Oct 2011 in our hospital.Results Twelve children were penicillin-resistant streptococcus pneumoniae.The ages ranged from 2 months to 10 years.Nine cases(75％) were aged less than 5 years,and 5 cases(41.6％) were aged less than 2 years.All cases were with fever,and with the nervous system symptoms involvement.All cases were with complications:9 cases(75％) with septicemia,8 cases (66.7％) with pneumonia.The white blood cells,blood C-reactive protein,peripheral blood procalcitonin,erythrocyte sedimentation rate,white cells and protein in cerebrospinal fluid were mostly significantly high,sugar in cerebrospinal fluid were low significantly.Eleven cases were eventually treatmented by vancomycin plus 3rd to 4rd generations of cephalosporins antibiotics or other antibiotics.Eight cases were cured,2 cases with serious sequela,and 2 cases died.Conclusion We should attach importance to the meningitis caused by streptococcus pneumoniae.For clinical suspects pneumonia streptococcus meningitis,to given the powerful therapy by vancomycin plus the other antibiotics,as early as possible.

Objective To investigate the value of acoustic radiation force impulse (ARFI)and color Doppler flow imaging (CDFI)in the diagnostic of acute rejection (AR)after liver transplantation.Methods B mode ultrasound,CDFI and ARFI exams were performed on fifty-eight patients who was diagnosed with AR through liver biopsy in our hospital.The liver allograft size,mean velocity of portal vein,hepatic vein spectrum waveform and shear-wave velocity were obtained and compared with the results of 30 healthy subjects as control group.Results Compare to control group,the AR group had a significant increase in liver allograft,decrease in mean velocity of portal vein,the elimination of triphasic wave of hepatic vein,and a significant increase in shear-wave velocity (P =0.000,0.000,0.007,0.000,respectively).The correlation coefficient between four criteria and grouping was 0.478,0.557,0.286,0.483,respectively.The area under ROC curves for diagnosing AR using the four criterias mentioned above was 0.914.Conclusions Combination of CDFI and ARFI in diagnosing of AR after liver transplantation has higher sensitivity and accuracy.
