Objective To study the relationship between Epstein-Barr virus(EBV) and Hapatocellular carcinoma (HCC). Methods Polymerase chain reaction (PCR) and immunohistochemical staining were applied to detect EBV in paraffin tissue sections from 78 HCC patients. Results EBV DNA was detected in 22 patients (28 2%) by PCR. Immunohistochemical staining of EBV LMP1 revealed that the positive signals were mainly localized in the tumor cells. Conclusions These observations suggest that EBV may pay a role in the development of HCC.

Objective To compare the clinical effects of palliative drainage to pancreatic and periampullary carcinoma which could not be excised with the operation.Methotis A retrospective study was accomplished on the palliative drainage treatment of 68 patients with pancreatic and petiampullary carcinoma hospitalized from 1996 to 2003.Results The disease course was two days to eight months.A definite preoperative diagnosis was made for 64 cases.Among them.single test diagnosed 24 cases and multiple tests diagnosed 40 cases.56 patients suffered from jaundice before operation.34 patients were treated by Roux-Y choledochojejunostomy.Choledochoduodenostomy was performed in 16 patients,cholecystduodenostomy for biliary by pass Was performed in 8 patients and stented internal drainage of the biliary duct in the liver and duodenostomy was performed in 10 patients.After reducing jaundice,12 patients was performed surgical resection.The second operation was performed in 4 patients because of postoperative jaundice and in 3 patients because of pylofic obstruction.The pefioperative compllcations include 4 cases of jaundice pyloric,3 cases of obstruction,2 cases of postoperative bleeding and 5 cases of infection of incisional wound.The aver-age stay in hospital waa 13.3 days(8～22 days).Conclusion Multiple tests were helpful to make a definite preoper-ative diagnosis.The selection of palliative drainage method based on the condition of patients had good curative effect in clinic.Surgocal exploration and reducing jaundice could set win conditions for second operation.

Objective To observe the clinical efficacy of Qianyang Mixture for the treatment of perimenopause hypertension. Methods Eighty cases of perimenopause hypertension patients were randomly divided into treatment group and control group, with 40 cases in each group. The two groups were given Amlodipine Besylate Tablets for oral taking, one tablet each time, once a day. The treatment group was treated with Qianyang Mixture, 35 mL for each time, twice a day, 1 h after meal. Course of treatment was 12 weeks. The changes of blood pressure, heart rate and sex hormone level of patients in both groups were observed, and efficacy of TCM syndrome were evaluated. Results After treatment, the heart rate, average daily blood pressure and morning blood pressure of the treatment group were lower than those of the control group, with statistical significance (P<0.05);After the treatment, the levels of estradiol in the treatment group were higher than those in the control group, with statistical significance (P<0.05). The total effective rate was 92.5% (37/40) in the treatment group and 80.0% (32/40) in the control group, with statistical significance (P<0.05). Conclusion Qianyang Mixture can obviously reduce blood pressure and heart rate of patients with perimenopause hypertension, and can regulate hormone levels, improve TCM symptoms.

Objective Exploration of TSH, FT3, FT4 changes in critical condition prior to death.Methods 84 patients that were anti-tumor therapy acceptable and not associated with the treatment of thyroid disease in patients with terminal tumors. Age from 24 to 85-year-old, male 56, female 28. The use of SELDI technology (surface-enhanced laser description / ionization time-of-flight mass spectrometry protein chip technology) checks to M/Z for the 11 100 + H～11 900 + H peak of the cluster, divided into the positive group for critically ill patients with early warning protein (LGT) and the negative group for it. All patients were given TSH, FT3, FT4 inspection. The results were statistically analyzed. Results TSH, FT3, FT4 in the LGT positive group was significantly lower than in the negative LGT group. There was no correlation between TSH,FT3 and FT4 in the LGT positive group;In the negative LGT group FT3 and FT4 had a positive correlation,and FT3 and TSH no relevance. Conclusion Thyroid function is normal in the stage of cancer patients stable condition. Possible pituitary-hypothyroidism may occur as the disease advances to the end or before death.This may be an important factor causing the acceleration to the death of the patients. However, the cause and effect between this phenomenon and the early warning of protein fingerprint group(LGT) is still not clear. In critical condition checking thyroid function and render supplementary amount of thyroid hormone in accordance with the checking results may be beneficial.

Objective To evaluate the feasibility of endooscopic minimally invasive McKeown esophagectomy in the treatment of esophageal carcinoma. Methods From June 2012 to August 2015, the data of 180 patients with esophageal carcinoma was retrospectively analyzed. The patients were divided into endoscopy McKeown esophagectomy group (EME group) and open McKeown esophagectomy group (OME group), each group had 90 patients. The clinical pathological data, perioperative data and postoperative complications between the two groups were analyzed. Results The operation time in EME group was longer than that in OME group [(289 ± 30) min vs. (252 ± 28) min, t= 8.063, P< 0.05]. The intraoperative blood loss and postoperative blood loss on the first day after operation in EME group were less than those in OME group [(178.94 ± 47.84) ml vs. (323.44 ± 59.51) ml, t=17.952, P<0.05; (220.93 ± 49.07) ml vs. (362.59 ± 68.37) ml, t= -15.968, P< 0.05]. There was no significant difference between the two groups in the number of lymph node dissection (t= -1.913), postoperative hospitalization days (χ2= 4.858) and postoperative complications (exact probability method) (all P> 0.05). Conclusions Endoscopic minimally invasive McKeown esophagectomy has the same effect as open surgery, and trauma is small. Therefore, for the patients who are suitable for the minimally invasive surgery, it can be preferred.

Objective To investigate the safety and therapeutic effect of intra-carotid infusion with cold sa line in rats with acute focal cerebral ischemia-reperfusion injury.Methods 60 rats were randomly divided into six groups:sham operated group,normal infusion group,stroke group,local hypothermic group,local normothermic group,and systemic infusion group.Brain infarct volume and cerebral water content were analyzed 48 h after ischemia.Neurological deficits were assessed using the mNSS 24 h and 48 h after infarction.Results In the local hypothermic group,brain temperature was reduced to 33 to 34 ℃ within 5 to 10 minutes,and this significantly low temperature maintained to nearly 60 minutes after infusion continued.Physiological variables were not significantly different among each time point (P ＞ 0.05).No significant morphological abnormality was found in brain sections stained with TTC and HE.Animals receiving local cold infusion significantly decreased infarct volume and brain water content compared to stroke group (P ＜ 0.05).Both 24 h and 48 h mNSS in local hypothermic group was significantly lower than those in other groups (P ＜ 0.05).Conclusions Intra-carotid infusion with cold saline can quickly and effectively reduce brain temperature and is a relatively safe cooling method.Local hypothermia significantly reduced brain infarct volume,decreased brain water content and improved neurological functional outcomes after brain ischemia.
