Method Hypoxanthine was administered via stomach or bait vessel,uricase inhibitor was injected subcutaneouslly,then the relative biochemical indicators of rats were inspected respectively at different periods of time after replicating the model. Results When hypoxanthine(50 g HX?kg-1bait vessel or 100 g HX?kg-1bait vessel) was administered via bait vessel,uricase inhibitor(200mg?kg-1) was injected subcutaneouslly,the uric acid in serum of different groups were much higher than control group(P

Objective To evaluate the clinical efficacy of endoscopic esophageal variceal ligation (EVL) for esophageal variceal bleeding (EVB) in elderly patients with hepatic cirrhosis.Methods From July 2007 to July 2013,clinical data of 198 patients who had been diagnosed with liver cirrhosis presenting with EVB were retrospectively analyzed.Among them,167 patients who had received EVL were divided into the elderly EVL group (n=97,age≥60 years) and the non-elderly EVL group (n=70,aged ＜ 60 years).The other 31 cases (aged ≥ 60 years) had received propranolol therapy.Treatment effectiveness,adverse effects,complications and the one-year survival rate of each group were analyzed.Results The efficacy rates and variceal recurrences were 77.3％ (75/97) and 78.6％ (55/70) in the elderly EVL group and 19.6％ (19/97) and 18.6％ (13/70) in the non-elderly EVL group,respectively,with no significant difference between the two groups (each P＞0.05).The re-bleeding rate was higher in the propranolol treatment group than in the elderly and non-elderly EVL groups [58.1％ (18/31) vs.24.7％ (24/97) vs,22.9％ (16/70),x2 =14.76,P =0.00].One-year survival rates in the elderly group,the non-elderly EVL group and the propranolol treatment group were 86.6 (84/97),88.6％ (62/70),64.5％ (20/31),respectively,with statistically significant differences between the three groups (x2 =10.24,P=0.01).Conclusions EVL is effective for the treatment of hepatic cirrhosis with EVB and can be used as a secondary prophylaxis measure for EVB in elderly patients with hepatic cirrhosis.

Objective To evaluate the efficacy of endoscopic variceal ligation(EVL)in esophageal variceal bleeding (EVB)in elderly patients with hepatic cirrhosis,and the safety of endoscopic operation under anesthesia.Methods From July 2007 to July 2013,170 patients diagnosed as liver cirrhosis complicated with EVB were retrospectively analyzed.Among them,139 patients who received EVL were divided into elderly anesthesia group (n=52,age≥60 years),elderly non-anesthesia group (n=45 ,age≥60 years)and non-elderly anesthesia group (n=42,age<60 years);the other 31 cases (age≥60 years) received propranolol therapy.The degree of satisfaction of visual fields and esophageal peristalsis under the gastroscope,the effect,adverse effects and complications of EVL,the recurrence of EVB and mortality of each group were analyzed.Two-way analysis of variance and crosstabs chi square test were performed for statistical analysis.Results The satisfaction rate of visual fields and esophageal peristalsis under the gastroscope were 82.5 % (104/126)and 89.7% (113/126)in elderly anesthesia group;82.6% (71/86) and 89.5 % (77/86)in non-elderly anesthesia group;40.3% (29/72)and 44.4% (32/72)in elderly non-anesthesia group.The satisfaction rate of visual fields and esophageal peristalsis under the gastroscope in anesthesia group were better than those in non-anesthesia group (χ2 =47.46,64.28;both P <0.01 ). The efficacy rates of EVL in elderly anesthesia group,elderly non-anesthesia group and non-elderly anesthesia group were 84.6%(44/52 ),68.9%(31/45 )and 81 .0%(34/42 ),respectively.The variceal recurrence rates were 19.2% (10/52 ),20.0% (9/45 )and 19.0% (8/42 ),respectively.There was no significant difference among them (all P > 0.05). Rebleeding rate of medication treatment group was 58.1%(18/31),which was obviously higher than that of elderly anesthesia group (19.2%,10/52 ), elderly non-anesthesia group (31 .1 %,14/45 )and non-elderly anesthesia group (23.8%,10/42 ),and the difference was statistically significant (χ2 =15 .10,P <0.01 ).No case of hepatic encephalopathy was found in elderly anesthesia group or non-elderly anesthesia group after EVL.The incidence of pneumonia in elderly non-anesthesia group was 4.2%(3/72),which was higher than that of elderly anesthesia group and non-elderly anesthesia group,and the difference was statistically significant (χ2 =8.93,P =0.01). The mortality within a month after EVL in elderly anesthesia group,elderly non-anesthesia group and non-elderly anesthesia group was 0,8.9% (4/45 )and 0,and the difference was statistically significant (χ2 =9.27,P =0.01).Conclusion The efficacy of EVL under anesthesia in EVB in elderly patients with liver cirrhosis was good,with no induction or aggravation of hepatic encephalopathy or irreversible complications were found.

Objective To improve the clinical blood level Through explore the feasibility of blood free surgery for congenital heart disease.Methods Collected 160 patients with congenital heart disease during January 2014 to December 2016 in our hospital,patients were divided into bloodless surgery experimental group (n =69) and blood transfusion treatment group (n=91) according to perioperative blood use.The basic data which including age,weight and GCS score,preoperative and postoperative hemoglobin(Hb),operation and postoperative pleural effusion drainage,intraoperative extracorporeal circulation time,mechanical ventilation time and blocking time,ICU stay,postoperative hospital stay,total hospital stay,reintubation and re-surgery of the two groups were compared.To investigate the effect of the implementation of bloodless surgical strategy for patients with congenital heart disease.Results 1) The difference between the two groups in age,body weight and GCS was not statistically significant (P＞0.05);2) The differences of Hb and intraoperative and postoperative pleural effusion drainage between two groups were not statistically significant (P＞0.05);3) The differences with cardiopulmonary bypass time,mechanical ventilation time,blocking time,re-intubation,re-surgery and ICU days of two groups were also not statistically significant (P ＞ 0.05);but bloodless surgery patients' postoperative hospitalization days and total hospitalization time was significantly lower than the control group (P＜0.05).Conclusion The implementation of bloodless surgery in congenital heart disease is safe and feasible.It can shorten the patient's hospitalization time.It is worth popularizing in clinical surgical treatment.

Objective: To investigate the role of JAK/STAT signal pathway in myocardial fibrosis (MF) of the chronic viral myocarditis (VMC) of mice and hypericin intervention study. Methods: Sixty healthy male Balb/c mice were used to establish the MF model by intermittent multiple ip injection of coxsackie B3, another 10 mice were used as normal control. Two months after the modeling, survival mice were randomly divided into four groups, model group, low- or high-dose hypericin group, and Captopril group. The mice were treated by Captopril or hypericin, respectively, ig administration, once a day. After 30 d, we took the myocardium of left ventricle to dye with Masson, to observe the cardiac histological changes. The serum type I collagen and type III collagen were detected by the means of ELISA, and the expression of JAK1 and STAT3 was observed with semi-quantitative RT-PCR and immunohistochemistry technique. Results: The model group, serum type I and type III collagen increased significantly, the expression level of JAK1/STAT3 was higher than that of the normal group, and the difference was significant (P < 0.05). While the hypericin and Captopril treatment could significantly reduce serum expression of type I and, type III collagen, and decrease JAK1/STAT3 expression. Histology showed the improvement of myocardial fibrosis degree, and a significant difference was observed when comparing with the model group (P < 0.05). Conclusion: In the process of chronic viral myocarditis, the activation of JAK1/STAT3 pathway may be one of pathological mechanisms of the MF-induced with type I and type III collagen increasing. Hypericin could inhibit the myocardial fibrosis by blocking JAK1/STAT3 pathway.
