ABSTRACT

Stroke is a common disease with complex and diverse clinical manifestations. Fufang Longmai Ningfang has been found to exhibit therapeutic effect on stroke, but its molecular mechanism for treating stroke remains unclear. The aim of this study was to investigate the molecular mechanism of Fufang Longmai Ningfang in the treatment of ischemic stroke by using the method of network pharmacology to define the active ingredients, target and molecular pathway of Fufang Longmai Ningfang. The TCMSP database was used to obtain the potential active components of Fufang Longmai Ningfang in the treatment of stroke. The CNKI database was used to verify the literature. The target was predicted and screened by PharmMapper and UniProt database. The target protein group was collected by TTD database. The Cytoscape software was used to construct a "component-target" network map, "component-target-disease" network map, and "target protein interaction" network map. The EAGLE algorithm was used for cluster analysis, the KEGG database was used for pathway analysis, and the SYBYL software was used for molecular docking for bioactivity verification. We found 39 potential active ingredients and 17 potential effective targets related to stroke. The representative active ingredients were ligustrazine, dioscin, and puerarin, and the related targets were MMP9, NOS3, NOS2, KDR, ALB, IL2, TGFB2, and CPB among others. The study found that carbon metabolism and HIF-1 signaling pathway are the main molecular pathways for treatment of stroke by Fufang Longmai Ningfang. The treatment of ischemic stroke by Fufang Longmai Ningfang may involve reduction of inflammatory response, enhancement of vascular permeability and inhibition of cerebral ischemia-reperfusion injury, providing a theoretical basis for their clinical use.

ABSTRACT

Stroke has become the second leading cause of death in the world, and the most common type is the ischemic stroke. Due to its rapid onset and complex conditions, ischemic stroke is a major neurological disorder that causes disability. Ischemic stroke mainly results from atherosclerosis, and the pathogenesis of ischemic stroke mainly includes energy metabolism disorders in the brain, the toxicity of excitatory amino acids, oxidative/nitrification stress, inflammatory response, apoptosis, and autophagy. With the characteristics of multi-component and multi-target, traditional Chinese medicine could be used to treat ischemic stroke at different stages. This article summarized the latest research progress on the pathogenesis of ischemic stroke and commonly used traditional Chinese medicine for treatment of ischemic stroke in order to provide references for the further research and clinical treatment of ischemic stroke.

ABSTRACT

<p><b>OBJECTIVE</b>To summarize the experience of lymph node dissection patterns in hand-assisted laparoscopic radical gastrectomy.</p><p><b>METHODS</b>One hundred and eleven patients with gastric carcinoma between December 2010 and September 2012 were operated by hand-assisted laparoscopic system designed by us. Clinical data were analyzed retrospectively. The lymph nodes were dissected from left to right together with total tumor resection(reverse lymph nodes scavenge pattern), then digestive tract was reconstructed.</p><p><b>RESULTS</b>Total gastrectomy, distal gastrectomy and proximal gastrectomy were performed in 57, 46 and 8 cases respectively. Combined cholecystectomy and lateral segment of left liver lobe were needed in 4 and 2 patients respectively, and 1 case underwent combined splenectomy and pancreatic body and tail resection. TNM staging of patients in I(, II(, III(A, III(B, and IIII( were 16, 8, 35, 14, and 38, respectively. Histological type was poorly differentiated in 78 cases, moderate differentiation in 26 cases and good differentiation in 7 cases. The incision length was(6.8±0.3) cm, blood loss was(238.4±113.6) ml, operative time was (171.9±23.3) min, number of removed lymph node was 17.2±5.7, hospital stay was (10.1±3.7) d, postoperative complication rate was 9.0%. One case died during perioperative time.</p><p><b>CONCLUSIONS</b>Hand-assisted laparoscopic D2 radical gastrectomy(reverse lymph nodes scavenge pattern) can avoid the multiple conversion of open-laparoscopic operation model, and is beneficial to the standardization for surgical procedure.</p>

ABSTRACT

<p><b>BACKGROUND</b>Effects of prophylactic somatostatin on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) and hyperamylasemia remain inconclusive. This study aimed to examine whether high-dose, long-term continuous infusion of somatostatin can reduce the incidence of PEP and post-ERCP hyperamylasemia.</p><p><b>METHODS</b>This was a randomized, placebo-controlled pilot trial. One hundred and twenty-four patients scheduled for ERCP from December 2008 to May 2010 randomly received one of the following three interventions: pre-ERCP somatostatin (0.5 mg/h for 24 hours, starting 1 hour prior to ERCP; n = 36), post-ERCP somatostatin (0.5 mg/h for 24 hours, starting 1 hour after ERCP; n = 47), or placebo (saline for 24 hours, starting 1 hour prior to ERCP; n = 41). Serum amylase and lipase concentrations were measured 1 to 3 hours prior to ERCP and 6, 24, and 48 hours after ERCP.</p><p><b>RESULTS</b>The three groups did not differ in age, gender, medical history, or ERCP procedure (catheterization using contrast or guidewire, pancreatic duct visualization, procedure time, or procedure type). The rate of PEP was 13.7% (17/124) in the overall study sample and 16.7% (6/36), 10.6% (5/47), and 14.6% (6/41) in the pre-ERCP somatostatin, post-ERCP somatostatin, and placebo groups, respectively (P = 0.715). The rate of post-ERCP hyperamylasemia was 19.4% (7/36), 21.3% (10/47), and 46.3% (19/41) in the pre-ERCP somatostatin, post-ERCP somatostatin, and placebo groups, respectively (P = 0.011).</p><p><b>CONCLUSIONS</b>High-dose, long-term continuous infusion (0.5 mg/h for 24 hours) of somatostatin, performed as either a pre- or post-ERCP, can reduce the incidence of hyperamylasemia, but not PEP.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the short-term outcomes after hand-assisted laparoscopic radical gastrectomy.</p><p><b>METHODS</b>Between June 2010 and May 2011, a series of 15 patients underwent hand-assisted laparoscopic gastrectomy(HG), 16 patients underwent laparoscopic gastrectomy(LP), and 11 patients underwent open gastrectomy(OP). Short-term outcomes included operative time, blood loss, lymph nodes harvested, and the length of incision were collected after operation.</p><p><b>RESULTS</b>The operative time was 150-200 min in HG, 180-220 min in LP, and 150-200 min in OP respectively. The time of laparoscopic procedure was 18-58 and 70-100 min respectively. The average incision length was 6.8 cm in HG, 5.6 cm in LP, and 13.5 cm in OP. The average number of lymph nodes harvested was 17.6, 15.1 and 16.4 respectively. The average estimated blood loss was 228 ml, 278 ml, and 427 ml respectively. The mean length of hospital stay was 9.9, 10.8, and 12.4 d. No anastomotic leakage, bleeding, or gastric paralysis were found. One wound infection case was found in OP.</p><p><b>CONCLUSIONS</b>Hand-assisted laparoscopic gastrectomy is in concordance with the standardized treatment protocol for gastric cancer. Lymph node dissection is easier by HG, therefore HG can be an alternative for the radical resection of gastric cancer.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To develop 22 Chinese Mandarin monosyllable lists with good psychometrical equivalence. This study was to evaluate the test-retest reliability of these lists when it was used in speech recognition test in normal hearing dialectal speakers.</p><p><b>METHODS</b>Seven cities including Dalian, Shanghai, Hangzhou, Wuhan, Guangzhou, Fuzhou and Xiamen were selected as testing centers which contain 6 typical Chinese dialectal regions including north of China, East of China, north of Fujian, south of Fujian, Guangdong and mid-south of China. At each center, 22 local normal hearing people were selected to join this study. Every participant was tested by each recognition test of all 22 lists twice in two sessions and same test order respectively. The second run of testing was carried out within 10 days-1 month since first run of testing.</p><p><b>RESULTS</b>There was a significant correlations between scores obtained at the two sessions (r = 0.682, P < 0.01). Paired student-t test had shown that a gross score of all dialectal participants was significantly higher than that of initial test to retest (P < 0.01). The mean increment of score was (2.7 +/- 10.1)%. A significant difference of test-retest score in 7 sites was 19.8% and it was equal to 5 test items. A one way ANOVA analysis had indicated that there were statistically significant difference between the score improvement of 7 test sites (P < 0.01). Another analysis had shown that there was no significant correlation between test-retest score improvement and intra-session intervals (P = 0.947).</p><p><b>CONCLUSIONS</b>Mandarin monosyllabic recognition test seems to be more stable, and the present study has indicated a systematic differences in Chinese Mandarin monosyllable recognition scores between test and retest. Monosyllable recognition test is not susceptible to memory effect. Pearson's correction analysis is not suitable to evaluation for test-retest reliability.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore an effective method for treating Gentamicin-induced deafness and the mechanism.</p><p><b>METHODS</b>Guinea pigs were randomly divided into 5 groups: normal control group (group A), model group (group B), Ligustrazine group (group C), acupuncture group (group D) and Ligustrazine plus acupuncture group (group E). The group C, D and E were treated respectively by simple Ligustrazine, simple acupuncture at "Tinggong" (SI 19), "Yifeng" (TE 17), and "Waiguan" (TE 5), and Ligustrazine plus acupuncture. Ten days later, the auditory brainstem response (ABR) thresholds for the wave III , apoptosis and expressions of Bcl-2 and Bax proteins in the organ of Corti of the guinea pig were detected.</p><p><b>RESULTS</b>In the group E, the ABR threshold was significantly lower than that in the group C (P<0.05), and apoptotic cells, the expression of Bax protein and the ratio of Bax/Bcl-2 were lower than those in the group C and D in the organ of Corti, and Bcl-2 protein expression was increased.</p><p><b>CONCLUSION</b>Acupuncture at "Tinggong" (SI 19), "Yifeng" (TE 17), and "Waiguan" (TE 5) has a certain target-synergistic action on Ligustrazine and can increase therapeutic effect of Ligustrazine on Gentamicin-induced deafness, which are possible related with the inhibition of apoptosis, down-regulation of Bax expression and up-regulation of Bcl-2 expression.</p>

ABSTRACT

<p><b>OBJECTIVE</b>Irinotecan (CPT-11), a specific inhibitor of topoisomerase I, has been proven to be effective in the treatment of refractory or metastatic colorectal cancer. Furthermore, several first line phase III trials of the combination therapy (FOLFIRI) using CPT-11 and fuorouracil/leucovorin (5-Fu/LV) were reported to have significant improvement in treatment result. Therefore, we designed a multicenter clinical study to observe the overall survival (OS), time to death (TTD), time to progression (TTP), efficacy and safety of FOLFIRI regimen for patients with refractory or metastatic colorectal cancer after first line chemotherapy failure.</p><p><b>METHODS</b>Patients with metastatic or refractory colorectal cancer after first line oxaliplatin-based chemotherapy failure were enrolled into this prospective, one arm and open-labeled multicenter study. Irinotecan 180 mg/m2 was administered biweekly on D1, LV 200 mg/m2 by intravenous infusion in 2 hours before bolus intravenous injection of 5-Fu 400 mg/m2, then followed immediately by intravenous infusion of 5-Fu 2.4 g/m2 in 46 hours. OS, TTD, TTP, response rate (RR) and adverse events were assessed according to RSCIST criteria and NCIC-CTG CTCAE (3.0).</p><p><b>RESULTS</b>Sixty-six patients were valuable for safety assessment and and 61 for efficacy. There was no CR patient in this series. Ten patients had PR, 35 SD (57.4% ) and 16 PD (26.2%) with a response rate of 16.4% (10/61). The median TTP was 5.0 months (1-12 months), median TTD 9.9 months (5-27 months)and median OS 18.2 months (7-33 months). The adverse events including nausea,vomiting, anorexia,diarrhea, leucopenia and cholinergic syndrome were frequent, but usually in I - II degree. The rate of III/IV degree diarrhea and leucopenia was 7.6% and 22.7%, respectively.</p><p><b>CONCLUSION</b>The regimen of irinotecan plus fuorouracil/leucovorin (FOLFIRI) is effective and well-tolerated as a second-line chemotherapy and may prolong the overall survival for the patient with refractory or metastatic colorectal cancer.</p>
