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 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 explore the regulation of PI3K-mTOR signaling pathways on autophagy of hippocampus nerve cells after subarachnoid hemorrhage (SAH)in rats.Methods We randomly divided 72 male Sprague-Dawley rats into sham group,SAH model group and LY294002 group with 24 rats in each group.We established SAH model with the secondary injection of blood method while the sham group was not injected with blood.PI3K signaling pathways specific inhibitor LY294002 was injected with 500μmol per rat 30 minutes before modeling.After 6,24,72 and 144 h morphologic changes of hippocampus CA1 neural cells were observed by microscopy;the expression levels of PI3K,mTOR,Beclin-1 and LC3-Ⅱ were detected by immunohistochemical method.Results The density of survival neurons in the SAH group was significantly lower than that in the control group (P<0.05),PI3K-mTOR signaling pathways were activated obviously,and the expressions of Beclin 1 and LC3-Ⅱ were significantly higher than those in the control group (P<0.05 ).The number of survival neurons significantly decreased in the LY294002 group compared with the SAH group at each time point (P<0.05),PI3K-mTOR signaling pathways were suppressed.The expressions of Beclin-1 and LC3-Ⅱ were significantly lower than those in the SAH group (P<0.05).Conclusion PI3K-mTOR signaling pathways protect neurons by activating the autophagy of neurons after SAH.

Objective To investigate the effect of BQ-123 on the ability of learning and memory and nerve cell autophagy in hippocam-pus in rats with subarachnoid hemorrhage (SAH). Methods 72 male Sprague-Dawley rats were randomly divided into sham group, SAH model group (SAH group) and BQ-123 group with 24 rats in each group. SAH model was established by injecting the autologous blood into cisterna magna twice. The sham group was not injected blood. BQ-123 group received intracerebroventricular injection with BQ-123 18μg 30 minutes before modeling. 6, 24, 72 and 144 hours after modeling, the passive avoidance latency (PAL) and active avoidance reaction rate (AARR) were tested with Shutter Box Test, the nerve cell morphological changes of hippocampus were observed with HE staining, and the expressions of Beclin-1 and LC3-II were detected with immunohistochemical staining. Results Compared with the sham group, the PAL pro-longed, the AARR decreased (P<0.05), the nerve cells in the hippocampus reduced (P<0.05), and the expressions of Beclin-1 and LC3-II in-creased (P<0.05) in SAH group. Compared with SAH group, PAL shortened (P<0.05), AARR increased (P<0.05), the nerve cells in the hip-pocampus increased (P<0.05), and the expressions of Beclin-1 and LC3-II increased (P<0.05) in BQ-123 group. Conclusion BQ-123 can promote the recovery of learning and memory ability, which may relate to the activation of nerve cell autophagy in the hippocampus.

Object To investigate the effects of Congsheng Capsule (CSC) on free radical change after cerebral ischemia reperfusion, and analyze the mechanisms of CSC anti cerebral ischemia action. Methods Bilateral carotid artery occlusion and reperfusion combined with tail bleeding hypotension were employed in this study. Changes in free radicals were observed by means of spectro photometry. Results CSC 1, 3, 9 g/kg could enhance SOD activity, reduce the MDA content, and decrease NOS activity and NO content. Conclusion The protective effects of CSC on cerebral ischemia may be mediated by its anti free radical and NO damage.

Object To investigate the profective effects of Congsheng Capsule (CSC) on cultured cerebral cortical neurons after cerebral ischemia reperfusion in order to study the anticerebral ischemia effect of CSC. Methods Drug containing serum was used to study the protective effect of CSC on neurons damaged during hypo glucos and hypoxia (3 h)/reoxygenation (0, 3, 6, 18 h), the demage to neurons was reflected by the increase in activity of lactate dehydrogenase (LDH) released from cells into culture medium and the changes of apoptosic cells which were studied by flow cytometry. Results The serum preparation of CSC (2, 4, 8 g/kg) attenuated neuronal damage during hypo glucos and hypoxia (3 h)/reoxygenation (0, 3, 6, 18 h) by decreased LDH and changes in apoptosic cell numbers. Conclusion CSC has protective effects on cerebral ischemic damage.
