Objective To investigate the clinical value of antibody D5F3 and Survivin in patients with non small cell lung cancer.Methods 200 paraffin embedded specimens of patients with non small cell lung cancer tested by RT-PCR(including EML4-ALK mutant and wild type)from October 2012 to June 2014 were selected.The gene protein expression were tested by ALK new antibody D5F3 and the sensitivity and specificity were compared by negative and positive(+～3+).ResultsTest results show(+)the coincidence rate is 15.78％,(+ +)the coincidence rate is 27.27％and(+ + +)compliance rate was 87.5％,the difference was statistically significant(P<0.05).The expression of Survivin protein in NSCLC tissues was correlated with clinicopathological features.The positive rate of Survivin protein expression was correlated with the degree of differentiation(P<0.05),but not with other clinical and pathological features,with the decrease of differentiation,the positive rate of Survivin protein expression was significantly increased.Conclusion D5F3 and Survivin antibodies are highly sensitive and specific in patients with NSCLC,with the screening value,save social resources,for the majority of patients with lung cancer services.

Objective To investigate the effect of H 2 S and its synthetase inhibitor propargylglycine ( PAG) on the autophagic function in caerulein-induced acute pancreatitis ( AP) mice.Methods A total of 60 male BALB/c mice were randomly divided into control , AP, NaHS and PAG group using random number method.AP was induced in mice via hourly intraperitoneal injection of caerulein (50 μg/kg) continuously for 6 hours.NaHS and PAG group received NaHS (10 mg/kg) or PAG (50 mg/kg) 1 h before the AP induction . A equal volume of normal saline solution was injected in control group and AP group .All the mice were killed at 12 h after the first caerulein injection and blood sample was collected for the detection of serum amylase and lipase content.Deproteinization spectrometry was used to detect serum H 2 S content, and pancreatic tissue was pathological examined and scored . Real-time PCR detected mRNA expression of CSE , and the protein expression of LC3-Ⅱ/LC3 Ⅰand p62 was measured using Western blot .Results Serum amylase, lipase, H2S, CSE mRNA, LC3Ⅱ/LC3Ⅰand p62 were (2 700 ±100)U/L, (70 ±20)U/L,(22.9 ±1.7)mmol/L, 1.0 ±0.1,0.419 ±0.080, 0.227 ±0.140 in control group; (17 290 ±500)U/L,(520 ±40)U/L, (31.3 ± 3.0)mmol/L, 5.4 ±0.4, 1.184 ±0.120, 1.985 ±0.210 in AP group; (27 784 ±1 200)U/L, (900 ± 80)U/L,(38.6 ±3.3)mmol/L, 6.9 ±0.9,1.600 ±0.210, 4.229 ±0.050 in NaHS group; (13 750 ± 2 000)U/L,(370 ±20)U/L, (24.5 ±2.1)mmol/L, 4.2 ±0.5, 0.745 ±0.130, 1.203 ±0.080 in PAG group.All those biomarkers detected above in AP group significantly increased compared with control group , which were much lower than those in NaHS group , but higher than those in PAG group , and the differences were statistically significant (all P<0.05).Pancreatic histological damage in NaHS group was more severe than that in AP group , which in PAG group was less severe than that in AP group .Conclusions PAG could greatly decrease serum amylase and lipase level , and reduce the damage on autophagy and the severity of AP .

Objective To investigate the parameters of liver tissue in SD rats and beagle dogs and to supply evidence for toxicologic pathological evaluation.Methods Forty SD rats and twenty beagle dogs,male in half,were used for the observation.SD rats were sacrificed at the age of 12 weeks and the beagles at the age of 12 months.After complete necropsy examination,all livers were fixed in 10 % neutral buffered formalin solution,embedded in paraffin,sliced at a thickness of 5 ? m and stained with hematoxylin and eosin(HE).The distance of central vein and portal area,and that of central veins in the neighbored lobules were measured by means of an image analyzer Spot Advanced.The difference of the above distance between beagles and rats,and that between male and female were compared.Results The distance of central veins in the neighbored lobules was about 883 ? m in the beagles and about 496 ? m in SD rats,and the distance between lobule center and portal area was about 511 ? m in beagle dogs and about 410 ? m in SD rats.There was no difference between the male and the female.Conclusion The distance of central veins in the neighbored lobules in beagle dogs is longer than that in SD rats,so does the distance between lobule center and portal area.The sex of the animal has no influnce on the size of the lobules.

Objective To investigate the clinical efficacy of Telmisartan combined with Atorvastatin in treating patients with idiopathic paroxysmal atrial fibrillation(IPAF).Methods 70 cases of IPAF were randomly divided into study group(given treatment of Telmisartan combined with Atorvastatin)and control group(given treatment of Telmisartan),35 cases in each group,all patients got 2 years follow-up visit.The change of CRP and the arrhythmia recurrence were observed after treatment.Results After surgery,patients were better than before,but the efficiency in study group was significantly higher than control group(88.6％ vs 68.6％,P ＜0.05);CRP of the two groups were significantly reduced after treatment,two groups have significant difference(P ＜ 0.05).Conclusion Curative effect of atorvastatin combined with telmisartan on IPAF is better than that of telmisartan treatment and clinical implementation should be promoted.

Objective To investigate the relationship among Helicobacter pylori (Hp) infection, serum gastrin level and colorectal carcinoma. Methods Fasting serum samples from 47 consecutive patients with colorectal carcinoma and 30 demoographically matched colonoscopy-negative controls were detected for serum gastrin levels and IgG antibodies against Hp (Hp IgG) by enzyme linked immunosorbent assay. Some of them accepted 14C urease breath test and/or rapid urease test after undergoing endoscopy. Hp infection was affirmed when at least two of the three tests were positive. Results The Hp infection incidence was significantly higher in patients with eoloreetal carcinoma (61.7%, 29/47) as compared with controls (36.7%, 11/30) (P<0.05). The Hp infection incidence in distal distribution of carcinoma was higher than that in controls, and in female carcinoma was higher than that in female controls(P <0.05). Mean fasting serum gas-trin levels were significantly higher in patients with coloreetal carcinoma[(139.7±53.3 ) ng/L]than those in controls [(89.5±26.1 ) ng/L] (P < 0.01 ). There was a significant association between hypergastrinemia and distal distribution of carcinoma. Conclusion Increasing serum gastrin levels, higher Hp infection incidence has a positive relationship with colorectal carcinoma.

Objective To study the methylation status of secreted frizzled-related protein (SFRP) 1 and SFRP2 genes in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and the relationship between the methylation status of the two genes and the development of HCC.Methods Using methylation-specific polymerase chain reaction (MSP) to detect methylation status of SFRP1 and SFRP2 genes of 45 specimens of HCC tissue and adjacent non-tumorous liver tissue from HCC patients during operations,and 6 normal liver tissues from patients with cholecystolithiasis or hepatic hemangiomas. The data were analyzed by chi-square test and Fisher exact test. Results SFRP1 gene methylation was detected in 28 HCC tissues and 16 adjacent non-tumorous liver tissues,accounted for 62.2% and 35.6%,respectively;and SFRP2 gene methylation was detected in 23 HCC tissues and 13 adjacent non-tumorous liver tissues,accounted for 51.1% and 28.9%,respectively;while no methylation was detected in 6 samples of normal liver tissues. There was no significant difference between the methylation of SFRP1 and SFRP2 genes in HCC tissues and gender,age,HBV serum markers,types of adjacent non-tumorous liver tissues,metastasis and pathological stage (P＞0.05).The abnormal methylation status between SFRP1 and SFRP2 genes was linear correlated in HCC tissues (r=0.381,P=0.01).Conclusion Hypermethylation of SFRP1 and SFRP2 genes frequently occurs in HBV-related HCC,which may be an important molecular biomarker for prediction of hepatocarcinogenesis in the future.

Objective To explore the effect of Botulinum toxin type A (BTX-A) injection combined with rehabilitation training and medicated bath on spasm for children with cerebral palsy. Methods 80 children with spastic and mixed cerebral palsy were randomly divided into two groups with 40 cases in each group. The control group received physical therapy, and the observation group received BTX-A injection and rehabilitation training and medicated bath. They were assessed with modified Ashworth scale (MAS) and Gross Motor Function Measure (GMFM-88) before and 3 months after treatment. Results The scores of MAS and GMFM were better in 2 groups after treatment (P<0.05) and the observation group was better than that of the control group (P<0.05). Conclusion BTX-A injection combined with medicated bath can reduce muscle tension, improve gross motor function of children with spastic and mixed cerebral palsy.

Objective To evaluate the application of cough reflex testing with various concentrations of citric acid for dysphagia post stroke. Methods 20 normal controls (NC), 20 stroke patients with dysphagia (SD) and 20 stroke patients without dysphagia (SND) were tested with cough reflex inhalated 4 kinds of dosage of citric acid: 0.2 mol/L, 0.4 mol/L, 0.6 mol/L and 0.8 mol/L. Results The incidence of pass (coughed twice or more) decreased in the SD compared with those in the NC as inhalated citric acid of 0.2 mol/L and 0.4 mol/L (P< 0.05), and decreased under 0.4 mol/L compared with the SND (P<0.05). There was no significant difference between the SND and the NC (P>0.05). 90% of the NC passed as inhalated citric acid of 0.4 mol/L; however, it was 45% in the SD, and increased when they inhalated more dosage of citric acid (P<0.05). The incidence of pass decreased under 0.2 mol/L citric acid in the SND compared with other concentration (P<0.05). The result of the test was reliable interrater (κ=0.97). The incidence of cough was consistent of 96.8% with the same concentration. No asthma and asphyxia was observed. Conclusion Cough reflex testing with citric acid inhalation can be used to assess the defensive function of airway in lower concentration for dysphagia after stroke.

Objective To evaluate the utility of multi-slice computed tomography (MSCT) in assessing acute non-reperfused myocardial infarct size. Methods Seven domestic pigs (mean weight 17.3 ± 1.9 kg) underwent ligation of the distal left anterior descending artery to establish a model of acute myocardial infarction (MI). MSCT and triphenyltetrazolium chloride (TTC) staining were performed two hours later. The following data were acquired and analyzed:MI volume (%), CT values of the infarcted region, left ventricular cavity and normal cardiac tissue at various scanning time-points (1, 5, 10, 15, 20 min after contrast injection). Results Using MSCT, the overall MI volume showed a time-dependent decrease, with a reduction of 28.87%after 20 min. The greatest reduction occurred at the 5 min time-point. In TTC staining, MI volume was 9.87%± 2.44%. When MI size, as determined by MSCT, was compared with that by TTC staining in Bland-Altman plots, there was a better agreement at 5, 10, and 15 min time-points at 1 and 20 min. Conclusions The study indicates that double-phase scanning examination using MSCT is a useful tool to assess MI size, and the optimal late-phase scanning time-point set within 5-15 min of contrast injection.
