Objective To investigate the mRNA expression of secondary lymphoid tissue chemokine (SLC) in human gastric carcinoma. Method The study was designed to investigate semi-quantitatively the expression of SLC mRNA in gastric carcinoma and metastatic lymph nodes by reverse transcription-polymerase chain reaction.Result The expression of SLC mRNA in the gastric cancer tissues was markedly reduced compared with that in adjacent noncancer tissues. The average tumor/normal (T/N) ratio determined by RT-PCR was 0.43?0.08 in 29 patients.Metastatic lymph node/normal ratio was 0.63?0.07.Negative lymph node/normal ratio was 1.19?0.11. As a control,the mean G3PDH T/N ratio was 1.16?0.06,there was no correlation between SLC mRNA expression and clinicopathological characteristics in gastric cancer.ConclusionSLC mRNA expression is suppressed in the gastric tumours. SLC may play an important role in the early stage of carcinogenesis.

Objective To investigate the effect of transabdominal gastroesophageal stapling in management of variceal bleeding in portal hypertension with Hassabi operation and sum up our clinical experience.Methods Retrospective analysis of 48 cases with portal hypertension operated by transabdominal gastroesophageal stapling between May,1998 and Oct.2005.The elimination of oesophagus venous、the rebleeding rate、the operation mortality、the stricture and the fistula rate and the index that influences the liver function were maily observed.Results No case suffered rebleeding and hepatal encephalopathy during the hospitaligation of the patients.Esophageal varices disappeared or reduced in all cases.One case resulted from stricture and one case died of multiple organ failure.Conclusions Transabdominal extensive oesophagogastric devascularization combined with gastrooesophageal stapling is an effective and safe procedure for control of acute variceal haemorrhage with satisfactory short-term control,but the long-term effect needs to be long follow-up for the patients.

Objective To observe the therapeutic efficacy and safety of recombinant tissue plasminogen activator (rt-PA) for treatment of patients with acute cerebral infarction and investigate the prognostic factors of thrombolysis. Methods The clinical data of 60 patients with acute cerebral infarction from January 2009 to November 2013 in Department of Emergency, Hangzhou Traditional Chinese Medicine Hospital were retrospectively analyzed;of them, 30 cases received intravenous rt-PA thrombolytic treatment, being in the thrombolytic group, 0.9 mg/kg rt-PA was given to the patient within 4.5 hours after the disease onset, the total dosage could not exceed 90 mg, in which 10%was intravenously injected and the rest 90%was intravenously dripped slowly within 60 minutes. That another 30 cases did not undergo thrombolytic therapy was assigned as the control group, and they took aspirin, etc anti-platelet aggregation routine treatment. Before and after thrombolytic treatment for 1 hour, 24 hours and 14 days, the National Institutes of Health Stroke Scale (NIHSS) score was evaluated in the two groups;before and after thrombolytic therapy for 0.5, 1.0, and 1.5 hours, the patient's scores of Barthel index (BI) were observed in the two groups. In thrombolytic group, the situations of hemorrhage transformation, symptomatic hemorrhage and modified Rankin scale (mRS) score in 3 months of the patients with different ages, complications and NIHSS scores were observed. Results Before treatment, no statistically significant differences were found in the NIHSS score (15.2±3.6 vs. 15.5±3.3) and BI score (45.0±8.8 vs. 44.1±7.6) between the control group and thrombolytic group (both P>0.05);after treatment with the extension of time, the NIHSS score was gradually reduced, reaching the lowest level on the 14th day after thrombolytic treatment, while the BI score was gradually increased, reaching its peak at 1.5 hours after thrombolytic treatment, the changes being more prominent in thrombolytic group (NIHSS score:9.7±2.6 vs. 12.8±4.2, BI score:82.6±7.8 vs. 69.6±9.8, both P<0.05). In thrombolytic group, there were cerebral hemorrhage transformation 2 cases, gum bleeding 3 cases, skin bleeding 1 case, urethral bleeding 1 case, gastrointestinal bleeding and black stool 1 case. In control group, cerebral hemorrhage transformation was seen in 1 case. There was no obvious systemic hemorrhage in the two groups. In the 30 cases in thrombolytic group, the baseline NIHSS score of patients>80 years old was higher than that in cases≤80 years old (15 vs. 12); the age (years: 71.0±4.1 vs. 61.5±2.6), baseline NIHSS score (14 vs. 11) and bleeding conversion rate [37.50% (3/8) vs. 18.18% (4/22)] of cases with atrial fibrillation were higher than those not complicated with atrial fibrillation; the NIHSS score of cases with elevated international normalized ratio (INR) was lower than those without elevated INR (11 vs. 14);The bleeding conversion rate [16.67%(1/6) vs. 29.17%(7/24)] with NIHSS score≤4 were lower than those with NIHSS score>4;the mRS score in 3 months (4 vs. 2), and percentage of 3-month mRS score≤2 [11.1%(1/9) vs. 52.38%(11/21)] in cases with NIHSS score≥20 was higher than that in cases with NIHSS score<20 (all P<0.05). The fatality rate of two groups was 3.33%. Conclusions The intravenous rt-PA thrombolytic treatment can significantly promote the early recovery of neurologic impairment for patients with acute cerebral infarction. The therapy can improve the prognosis and its safety is relatively good. Meanwhile it is similarly effective for cases over 80, with complications such as atrial fibrillation, raised INR, and with different degrees of severity.
