Objective To evaluate hepatectomy for liver metastasis in patients of gastric carcinoma.Methods Clinical data of 32 gastric cancer cases undergoing hepatectomy for hepatic metastatic tumor were reviewed retrospectively from 2006 to 2012.16 cases underwent radical gastrectomy and synchronous hepatectomy for liver metastasis,the remaining 16 cases underwent radical resection of gastric cancer and liver resection heterochronously.The relationship between prognosis and clinicopathology was analyzed.Results The overall survival rates were 84％,50％ and 37％ in 1 year,3 years and 5 years.The median survival time was 32 months.Gastric cancer invasion depth,intravascular tumor thrombi,lymphatic metastasis and intraoperative blood transfusion was related to poor prognosis by single factor analysis,while gastric serosal invasion,tumor thrombus and liver metastasis tumor ＞ 5 cm related to poor prognosis by multiple factors analysis.Conclusions Gastric cancer patients with liver metastasis who underwent hepatic resection can achieve good prognosis if hepatic metastatic tumor ＜ 5cm or the primary gastric cancer does not invade the serosa and without tumor thrombus.

An analytical method for simultaneous determination of five quinolones in spicy soup was developed. Spicy soup samples were firstly extracted by EDTA-Mcllvaine buffer at pH 4, then purified and concentrated by a novel Packed fiber solid phase extraction ( PFSPE ) coulumn. The extracted liquid supernatant was loaded onto the column, rinsed with water, and then eluted with 2% ammoniated methanol. The mobile phase was methanol-water-phosphoric acid (25:75:0. 1, V/V, adjusting the pH to 2. 8 with triethylamine) . These analytes were quantified by high performance liquid chromatography-fluorimetric detector( HPLC-FLD) at excitation and emission wavelength of 280 nm and 450 nm respectively. Recoveries of spiked quinolone antibiotics in spicy soup were from 72 . 1% to 110 . 3% with intraday relative standard deviation (RSD) between 1. 6% and 4. 3% and inter-day RSD from 2. 0% to 4. 3%. Limit of detection (LOD) and limit of quantitation(LOQ) were from 1. 2 to 5. 4 μg/L and from 3. 9 to 18 μg/L, respectively. The method could be applied to determine the quinolones in spicy soup.

Purpose: To investigate the relationship between quantity of suppurative moxibustion and its effect on allergic asthma. Methods: The patients were randomly divided into suppurative moxibustion 9 cones group, 3 cones group and 6 cones group. The biggest area, scar-losing time, suppurating time and scarring time of post-moxibustion sore, and the clinical effects of each group were observed. Results: The biggest post-moxibustion sore area of 9 cones group was bigger than 3 cones group but had no difference with 6 cones group,and scar-losing time, suppurating time and scarring time of post-moxibustion sore of each group were of no difference. The clinical effects of 9 cones were better than 3 cones group but have no difference with 6 cones group. Conclusion: The quantity of suppurative moxibustion is in close association with the effects in the treatment of allergic asthma, and eventually becomes the key factor for good results.

Objective To observe the effects of extracorporeal shock wave therapy (ESWT) on spasticity of biceps brachii after stroke. Methods 12 patients with spasticity of biceps brachii after stroke were divided into control group (n=6) and ESWT group (n=6). The ESWT group received a session of ESWT and the control group received placebo treatment. All patients were assessed before and immediately after treatment, including integrated electromyogram (iEMG) and co-contraction ratio during maximum isometric voluntary contraction (MIVC) of elbow extension with surface electromyography, the modified Ashworth Scale (MAS) and content of shoulder and elbow of Fugl-Meyer Assessment (FMA). Results The scores of MAS and FMA, the iEMG and the cocontraction ratio of biceps brachii improved in the ESWT group after the treatment (P<0.05), and improved more than those in the control group (P<0.05). Conclusion ESWT can immediately relieve the spasticity of biceps brachii, inhibit the cocontraction of biceps brachii during elbow extension and improve the motor function of upper limb in patients post stroke.

Objective To explore the diagnostic value and optimal cut-off point of symptom index (SI) in gastroesophageal reflux-induced chronic cough (GERC).Methods The recordings of multichannel intraluminal esophageal impedance and pH monitoring were retrospectively analyzed in 118 patients with suspicious GERC.SI for all the refluxes,acid reflux and non-acid reflux was calculated respectively by analyzing the temporal association between detected reflux and cough recorded on diary card.Based on the favorable response to the anti-reflux therapy,the diagnostic value for GERC of SI was evaluated and compared with that of the symptom association probability (SAP).Results GERC was definitely determined in 100 patients (84.7％).When SI for all the refluxes was used for the diagnosis of GERC,the cut-off point of ≥45％ had the highest diagnostic efficacy,with the sensitivity of 56.0％,the specificity of 83.3％and Youden index of 0.393.SI for acid or non-acid reflux had the same optimal cut-off point of ≥30％ and presented with the similar efficacy in the diagnosis of acid or non-acid GERC.Compared with SAP of ≥75％,SIforall the refluxes of ≥45％ had a lower sensitivity (56.0％ vs 75.0％,x2 =7.988,P=0.005),a higher specificity (83.3％ vs 44.4％,x2 =5.900,P =0.015) and the comparable positive or negative predictive value in the diagnosis of GERC.The diagnostic accuracy for GERC was further improved when combining SI for all the refluxes with SAP.Conclusion SI for all the refluxes has a diagnostic value similar to SAP and its optimal cut-off point for GERC may be ≥45％.

Objective: To evaluate the effects and partly mechanism of Qileng decoction(QLD,芪棱汤) resisting focal cerebral ischemia/reperfusion(I/R) injury in rats by apoptosis and signal transduction pathway.Methods: The rats were randomly divided into three groups including sham operation group,normal saline(NS) control group and QLD group.The model of focal cerebral I/R injury was induced by using modified thread embolizing in rats.Rats were evaluated by neurologic function score at 2 hours after ischemia and 2,4,6,12,24 and 48 hours after cerebral reperfusion,and the pathological changes of nerve cells and mitochondria ultrastructure at pallium and hippocampus CA1 region were observed at 24 hours after reperfusion.Immunohistochemical method was performed to examine the expression of cytochrome C(cyt C) and caspase-9 at different time points after reperfusion.Apoptosis of nerve cells in ischemic penumbra(IP) was also characterized by terminal deoxynucleotidyl-transferase mediated dUTP-biotin nick end labeling(TUNEL) method.Results: Compared with NS control group,neurologic function scores at different reperfusion time points were improved and the pathological changes were ameliorated at 24 hours after cerebral I/R in QLD group.Mitochondria hydropsia was alleviated,mitochondrial cristae fragmentation and granulum basale shedding were diminished,and mitochondrial basical morphology was retained.Meanwhile,apoptosis index(AI) was decreased and the expressions of cyt C and caspase-9 were reduced in IP in QLD group.Conclusion: QLD intervenes in mitochondria mediated and caspase-9 dependent apoptopic pathway.QLD lowers AI and plays a role of protecting nerve by maintaining mitochondrial basical form,stabilizing mitochondrial membrane and inhibiting the release of cyt C and activation of caspase-9.The above actions are possibly some parts of mechanisms of QLD resisting focal cerebral I/R injury.

Objective:To investigate the relationship between fester capacity and clinical efficacy on allergic asthma treated by scarring moxibustion.Methods:The patients were randomly divided into scarring moxibustion 9-cone group,3-cone group and 6-cone group.The biggest area,scab-lost time,first-festering time and scarring time of moxibustion sore,and the clinical efficacy in each group was observed.Results:The biggest post-moxibustion sore area in 9-cone group was larger than that in 3-cone group,but had no difference in comparison with 6-cone group;the scab-lost time,first-festering time and scarring time of post-moxibustion sore in each group were of no difference.The clinical efficacy was better in 9-cone group than in 3-cone group,but had no difference in comparison with the 6-cone group.Conclusion:Fester capacity in treating allergic asthma by scarring moxibustion is related to the clinical efficacy and definite fester capacity is the key to good results on allergic asthma.
