Objective To assess the relationship between eosinophil count and intracranial aneurysm (IA).Methods For the retrospective study,we collected data of the count of eosinophils obtained from the peripheral blood samples and other clinical data of 79 patients with IA admitted to our hospital between January 2014 and December 2015 and 65 healthy people as control group.Risk factors for IA were analyzed by multivariate Logistics regression analysis.Results Clinical characteristics were comparable between the two groups (P＞0.05).Compared with those in the control group,eosinophil and platelet counts in IA group were significantly higher [(0.18±0.12)109/L vs.(0.12±0.09)109/L;(196.44±57.33)109/L vs.(178.80±47.23)109/L,respectively;all P＜0.05],while platelet distribution width (PDW) and mean platelet volume (MPV) were lower [(13.95 ± 3.332)fL vs.(15.30±3.5)fL;(11.02±1.73)fL vs.(11.66±1.31)fL,respectively;all P＜0.05].Logistic regression analysis indicated that eosinophil was the independent risk factor for IA.Corclusion Our study demonstrated that increased eosinophil count is the independent risk factor for IA.

Objective To investigate the clinical value of preventive analgesia in patients with radical gastrectomy for gastric cancer.Methods The clinical data of 161 patients undergoing radical gastrectomy for gastric cancer at the Xijing Hospital from July 2012 to June 2013 were prospectively analyzed.A single-blind,randomized,controlled study was performed in the eligibe patients who were randomly divided into the preventive analgesia group and the control group based on a random number table.All the patients received major gastrectomy + Billroth Ⅱ anastomy or total gastrectomy + esophagojejunastomy,and then they received vein combined anesthesia and tracheal intubation.In the preventive analgesia group,10 mg dexamethasone and 200 mg parecoxib were administered by intravenous infusion before operation,7-8 mL ropivacaine (0.5％) were injected at the incisional site and transversus abdominis infiltration at open and close surgery and celecoxib was taken orally for 3 days.In the control group,vein analgesia pump was used after operation.The visual analogue scale (VAS),proportion of patients with postoperative out-off-bed activity time ＞ 8 hours,time of flatus,time of defecation and duration of hospital stay were recorded between the 2 groups.The measurement data with normal distribution were presented as x ± s.The comparison between groups was evaluated with the t test and repeated measures ANOVA.The data with skew distrubution and ordinal data were analyzed by the analysis of variance,and the count data were analyzed using the chi-square test.Results All the 161 patients who were screened for eligibility were randomly divided into the preventive analgesia group (87 patients) and the control group (74 patients).The scores of the VAS at postoperative day 1,2 and 3 were 2.8 ± 0.6,2.6 ± 0.4 and 1.8 ± 0.4 in the preventive analgesia group,and 5.3 ± 0.5,4.2 ± 0.6 and 2.4 ± 0.3 in the control group,with a significant difference between the 2 groups (F =4.25,P ＜ 0.05).The proportion of patients with postoperative first abmulation time ＞ 8 hours at postoperative day 1,2 and 3 were 8,17 and 20 in the preventive analgesia group,and 0,3 and 11 in the control group,with a significant difference between the 2 groups (x2 =7.60,10.26,3.16,P ＜ 0.05).The time of flatus,time of defecation and duration of hospital stay were (51 ± 24) hours,(61 ± 24) hours and (5.5 ± 3.0) days in the preventive analgesia group,compared with (71 ± 23) hours,(83 ± 30) hours and (6.3 ± 2.1) days in the control group,showing a significant difference between the 2 groups (t =5.32,5.04,0.17,P ＜ 0.05).All the patients in the 2 groups normally survived after surgery without respiratory depression,incision infection and adverse drug reaction.Conclusions Preventive analgesia in the perioperative treatment of patients with radical gastrectomy for gastric cancer could relieve the postoperative pain of patients,improve the bowel function and enhance the recovery of patients.Registry This study was registered with the Chinese Clinical Trial Registry with the registry number of ChiCTRTRC-11001440.

Objective To investigate the correlation between augmentation index (AI) of the radial artery and diastolic heart function in patients with hypertension.Methods Echocardiographs were obtained for 305 patients with hypertension.AI,pulse wave velocity (PWV) of peripheral arteries and serum pro-brain natriuretic peptide (proBNP) levels were determined.Correlations and receiver operating characteristic (ROC) curves were drawn between AI values and impaired diastolic function.Results AI levels were significantly increased in patients with impaired diastolic function diagnosed by ultrasound.Assessment of diastolic heart function based on proBNP levels revealed that AI and aortic pulse wave velocity were significantly elevated in patients with impaired diastolic function.The operating curve indicated that AI may be a more accurate and efficient index for the evaluation of impaired diastolic function compared to pWV.Correlation analysis also showed that proBNP levels had altered in parallel with changes in AI and PWV.After adjusting for various factors including age,gender,blood pressure and blood lipid,a positive correlation was observed between proBNP and AI with a correlation coefficient of 0.3697 (P =0.003).However,no correlation between proBNP and aortic PWV was seen after adjustment.Conclusions Changes in radial AI levels may reflect parallel changes in diastolic cardiac function in patients with hypertension,suggesting that AI may be utilized as a non-invasive clinical indicator of diastolic heart function.

Objective To discuss the value of diagnosing gastrointestinal dysfunction in.critically ill children.Methods Seventy-six critically ill patients were reviewed,48 cases combined with gastrointestinal dysfunction.Plasma D-lactate,intestinal fatty acid binding protein(IFABP)of serum and urine were performed in all patients,detected the sensitivity and specificity,ealculated the area under the ROC curve (AUC).Results Plasma D-Iactate level≥9.63 mg/L had a sensitivity of 85.2%,specificity of 70.9%,and AUC of 0.822 for diagnosing gastrointestinal dysfunction.Serum IFABP level≥0.129μg/L had a sensitivity of 65.2%,specificity of 63.8%,and AUC of 0.744 for diagnosing gastrointestinal dysfunction.Urine IFABP ≥0.330μg/Lhad a sensitivity of 78.3%,specificity of 72.3%,and AUC of 0.820 for diagnosing gastrointestinal dysfunction.There was no significant difference in AUC between plasma and urine IFABP(P＞0.05),there was no significant difference in AUC between serum D-lactate and serum IFABP(P＞0.05).Conclusions Plasma D-Lactgte,serum and urine WABP may be useful markers as warning gastrointestinal dysfunction of critically ill children.Plasma D-lactate and urine IFABP level may be more sensitively,but they need to be further studied.

Laparoscopic vagal-sparing esophagogastrectomy for the treatment of early esophageal cancer has the advantages of minimal invasion,functional sparing and better quality of life,and it can radically resect the tumor.The clinical data of 3 patients in the Daping Hospital of Third Military Medical University and 9 patients in the Xijing Hospital of Digestive Diseases who received laparoscopic vagal-sparing esophagogastrectomy from September 2009 to August 2013 were retrospectively analyzed.All the 12 patients were followed up for 1-24 months.One patient was complicated with transit hoarseness and 1 with cervical anastomotic fistular,and they were cured by conservative treatment; 1 patient was complicated with cervical anastomotic stricture,and was cured by dilatation for 3 times; no dysphagia and recurrence was observed in the other 9 patients during the follow-up.Laparoscopic vagal-sparing esophagogastrectomy is a good option for early esophageal cancer and benign esophageal diseases.

Objective To explore the effect of Exosomes isolated from the A549 lung cancer cells on the proliferation of these cells and their ho?mologous tumor cells,HCC827,and the role of the PI3K/Akt and SRC signaling pathways in this process. Methods Exosomes were isolated from the supernatant after density gradient centrifugation of A549 cells. The Exosomes morphology was observed by transmission electron microscopy. The expression of the Exosome?specific proteins was analyzed using Western blotting. Cell proliferation was investigated using the MTT assay. Re?sults The A549?derived Exosomes were 30?100 nm in diameter and had a bilayer membrane.Western blotting showed that CD9 was detected in these Exosomes. The isolated Exosomes promoted the proliferation of the A549 and the HCC827 cells in a dose?and time?dependent manner,ac?companied by the activation of Akt and SRC. Conclusion Exosomes isolated from A549 cells promote the proliferation of the secreting cells and the homologous tumor cells in a dose?and time?dependent manner. The mechanism may be related to the activation of Akt and SRC.

OBJECTIVE: To evaluate the efficacy and safety of Dinggui Oil Capsule in treating irritable bowel syndrome (IBS) with stagnation of qi and cold. METHODS: A prospective, randomized, placebo-controlled, double-blind clinical study was undertaken. One hundred and ninety-eight patients with IBS and syndrome of stagnation of qi and cold were randomly divided into high-dose Dinggui Oil group (DGO-H, 1.2 g, 3 times daily; n=66), low-dose Dinggui Oil group (DGO-L, 0.8 g, 3 times daily, n=66), and placebo group (placebo, 5.0 g, 3 times daily, n=66). Patients in the three groups were all treated for 2 weeks. RESULTS: The total significant effective rates for IBS were 54.1%, 28.8% and 21.9% in the DGO-H, DGO-L, and placebo groups, and the total effective rates for the syndrome of stagnation of qi and cold were 54.1%, 25.8% and 23.4% in the three groups, respectively. Dinggui Oil Capsule showed a higher efficacy than the placebo in relieving the abdominal pain (P<0.01). No adverse effects were found in this trial. CONCLUSION: Dinggui Oil Capsule is effective and safe in relieving abdominal pain due to IBS with stagnation of qi and cold.

BACKGROUNDTo summarize the preliminary experience on Iressa for refractory non-small cell lung cancer (NSCLC).

METHODSFifty-five patients with NSCLC, who failed after surgery, radiotherapy, chemotherapy or combination of the above modalities, were registered in this clinical trail. Prior to Iressa, 50 patients were in stage IV, and 5 in stage III. Iressa was administered orally at 250 mg, once a day until cancer progressed or severe toxicity occured, which made patients intolerable. The median time for administration of Iressa was 4 months.

RESULTSThe toxicity of Iressa was tolerable with 47% of skin toxicity (rash) and 2%-7% of diarrhea, nausea, orally mucosal ulceration and alopecia. Overall response rate was 20%. Different sites of distant metastases responded to Iressa in different ways with higher response rate for pulmonary disseminations. One quarter of patients felt improvement of their symptoms over 2 weeks. Median survival time for entire group was 5 months (1-17 months). Median time to progression (TTP) was 3.6 months. Survival at 6 months was 67%. Prognostic predictor, which could imply the outcome, was skin toxicity with higher response rate and longer survival time ( P < 0.05), and no relationship with sex, histological types of NSCLC and distant metastasis had been found.

CONCLUSIONSIressa could be tolerated by refractory NSCLC patients with acceptable side-effects, and have palliative effects.
