Methods Selected 100 cases with congestive heart failure and ventricular arrhythmia in our hospital from January 2011 to April 2017 as research objectives and divided them into two groups randomly with 50 cases in each group. Provided amiodarone to control group and provided amiodarone combined with bisoprolol to observation group. Compared two groups' arrhythmia and cardiac function, heart rate, ejection fraction, QT time (QTc) corrected for heart rate before and after treatment as well as adverse events. Results Observation group's effective rate of arrhythmia treatment and the effective rate of cardiac function were 94.00％, 96.00％, those were significant higher than control group's 70.00％, 78.00％ (P<0.05). Two groups' heart rate and ejection fraction score after 3 month treatment were significant higher than those before treatment (P<0.05), and observation group's improvement was more significant (P<0.05). Observation group's QTc was significantly prolonged after 3 months of treatment (P<0.05), but control group's QTc did not change significantly. There was no significant difference in the incidence of adverse reactions between the two groups. Results Amiodarone combined with bisoprolol has significant clinical effect on patients with congestive heart failure and ventricular arrhythmia. It is safe and worthy to be promoted clinically.

Objective To investigate the pattern of lymph node metastasis in patients with 17 and middle thoracic esophageal squamous cell carcinoma( ESCC). Methods Retrospective review the clinical data of 246 cases with T2 and middle thoracic esophageal squamous cell carcinoma who were treated by three-field lymphadenectomy. Analyze the relationship between clinical pathological factors and lymph node metastasis. Results Lymph node metastases were found in 129 of the 246 patients (52.4% ).The average number of resected lymph nodes was 25 per patient (rangel5 -59). The rates of lymph node metastasis were 28.9% in the neck, 28.5% in thoracic mediastinum and 22.0% in abdominal cavity for patients with T2 and middle thoracic ESCC. No significant difference in lymph node metastasis' rate was observed among the neck, thoracic mediastinum and abdominal cavity. Logistic-regression showed the length of tumor, tumor cell differentiation and angiolymphatic invasion were factors influencing lymph node metastasis. Conclusion Lymph node metastasis in T2 and middle thoracic ESCC has the characteristics of upward, downward and skip spreading. Patients with T2 and middle thoracic ESCC should be treated with radical surgery with three-field lymphadenectomy.

Objective To discuss the effective surgical treatment of intrahepatic lithiasis combined with high hepa-t ic duct strictures. Methods Two hundreds and sixteen cases of intra hepatic lithiasis and high hepatic duct strictures treated in this hospital fr om January 1993 to October 2002 were analysed retrospectively.Results One hundred and eighty- three cases underwent different selective operation by selected time; 33 case s complicated with acute obstructive suppurative cholangitis underwent emergency were performed single biliary drainage, in which 30 cases were re-operated. Th e operative procedure were: hepatic lobectomy,high cholangiotomy and plastic repair,exposure of hepatic duct of the 2nd and the 3rd order,and plastic re pair with own patch and choledochojejunostomy.Two hundreds and six cases w ere cured,the curative rate was 95.4%; 8 cases improved (3.7 %), and 2 cases died (0.9%).Conclusion The best effective surgical treat ment of intrahpatic lithiasis is hepatic lobectomy. Exposure of hepatic duct of the 2nd and the 3rd order is a satisfactory to release the hepatic duct str ictures and to clear the intrahepatic lithiasis. For patients with normal extr ahepatic bile duct and Oddi's function, plastic repair of bile duct with own patch is possible to keep the normal form and function. Cholang ioscopy may play an important role in the treatment of intrahepatic tr act lithiasis during operation.

Objective To discuss the feasibility of stone removal in laparoscopic choledocholithotomy by routine laparotomic instruments. Methods A total of 73 patients with common bile duct stones were divided randomly into 2 groups: the Experimental Group received laparoscopic stone removal by routine laparotomic instruments; the Control Group received stone removal by choledochoscopic net-basket. The stone-free rate, operative time, total hospitalization costs and postoperative complications between the two groups were compared. Results There were no statistical significances in stone-free rate between the Experimental Group ( 94.4% , 34/36) and the Control Group (94.6%, 35/37) ( ? 2=0.000, P =1.000). The operative time in the Experimental Group (150.9 min?26.8 min) was shorter than that in the Control Group (172.3 min?28.6 min) ( t=3.297, P =0.002), whereas the total hospitalization costs in the Experimental Group (4400 yuan?1100 yuan) was lower than that in the Control Group (5000 yuan?1300 yuan) ( t=2.126, P= 0.037). No severe operation-related complications were observed in both of the groups. Conclusions Laparoscopic choledocholithotomy by either routine laparotomic instruments or choledochoscopy is safe and effective. Stone removal by routine laparotomic instruments has the advantages of low costs and short operative time.

BACKGROUND: The formation of long-term memory includes acquisition, consolidation and reconsolidation. Reconsolidation is very important for the new memory transforming into stable memory. Stress is an important environmental factor in the process of learning and memory. Corticosterone is very important for stress response. At present, research about the impact of corticosterone on reconsolidation of novel object recognition memory is less. Thus, it is very important to test the impact of corticosterone on reconsolidation of novel object recognition memory in rats.
OBJECTIVE: To analyze the effects of corticosterone on the reconsolidation of novel object recognition memory in rats.
METHODS: (1) The rats were intraperitoneal y injected with corticosterone (0.1, 1 and 3 mg/kg) immediately after reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects. (2) The rats were intraperitoneal y injected with corticosterone (3 mg/kg) 6 hours after reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects. (3) The rats were intraperitoneal y injected with corticosterone 3 mg/kg without reactivation. The discrimination index was used to assess memory performance and calculated as the difference in time exploring the novel and familiar objects.
RESULTS AND CONCLUSION: Immediate injection of corticosterone 3 mg/kg after reactivation significantly decreased the discrimination index. At 6 hours after reactivation or without reactivation, corticosterone administration did not impact the discrimination index. These results confirmed that corticosterone administration immediately after reactivation impairs the reconsolidation of novel object recognition memory. The damage effect depends on the reactivation experience and the specific time window after reactivation.
