Objective To evaluate the effects of apolipoprotein-J(ApoJ)on hypoxia/reoxygenation(H/R)induced neonatal rat ventricular cells(NRVCs)injury and its related signaling pathways.Methods ApoJ high expression was achieved by infection with recombinant adenovirus in NRVCs.The three gas incubator was used to establish H/R model,SOD mimetic Mn(Ⅲ) tetrakis(4-benzoic acid)porphyrin chloride and eIF2α dephosphory inhibitor Salubrinal were performed the pretreatment.The NRVCs were divided into four groups:normal control group,H/R,ApoJ group,ApoJ+ H/R group,Mn(Ⅲ)TBAP+H/R group and Salubrinal +-H/R group.The cell viability was measured by MTT assay;the leakages of LDH,the expression of SOD and caspase-3/7 activity were detected by ELISA.The protein expression levels of ApoJ,Nox2/gp91phox,caspase-12,CHOP,and the phosphorylation level of eukaryotic initiation factor 2α(eIF2α)were determined by Western blot.Results ApoJ protein in myocardial cells was highly expressed after infection by recombinant adenoviru.Compared with the control group,the cell viability and the activity of SOD were significantly decreased,the leakages of LDH and the activity of caspase-3/7 were increased in the H/R group,the pro tein expression level of Nox2/gp91phox,caspase-12 and CHOP and the phosphorylation level of eIF2α were increased.Compared with the H/R group,the leakages of LDH and the activity of caspase-3/7 in the ApoJ overexpression group,Mn(Ⅲ)TBAP group and Salubirnal group were significantly decreased.ApoJ overexpression significantly increased the cell viability and the activity of SOD.Moreover,the protein expression level of Nox2/gp91phox,caspase-12 and CHOP were significantly decreased,while the phosphorylation level of eIF2α was markedly increased.Conclusion ApoJ alleviates H/R induced myocardial cellular injury by antioxidative stress and endoplasmic reticulum stress.

Objective To investigate The effect of Heat shock protein 70(HSP70) antisense oligonucleotides (ASO)to bladder carcinoma in mouse loaded with tumor.Methods The 40 mice loaded with tumor subcutaneously were established by cultured BIU-87 cells,and divided into 4 groups randomly when the subcutaneous neoplasms grew to about 100 mm3,namely,HSP70 mRNA ASO plus mitomycin C(MMC)group;HSP70 mRNA ASO group;MMC and blank control.HSP70 mRNA ASO were injected into neoplasms,10mmg/kg weight,twice every week,and MMC 0.1mg/kg weight,twice every week,and the above schemes were replaced with normal saline to blank.The neoplasms were peeled off,photograghed and weighed in 30 days.HSP70 expressions were examined with reverse transcription polymerase chain reaction (RT-PCR),mierovaseular density(MVD)was evaluated by immunohis to chemical staining and the tumor cells apoptosis was detected by terrainal deoxynucleotidyl transferase(TdT)-mediated dUTP-biotin nick end labeling technique (TUNEL).Results The tumor inhibition rate in ASO+MMC surpassed 50%.more than ASO or MMC respectively,and the differences were significantly(P＜0.05).The ASO and MMC exceeded blank group respectively(P＜0.05).The ASO was the same as the MMC(P＞0.05).The apoptotic index(AI)in ASO+MMC surpassed the other three groups (P＜0.05).The difference between ASO and MMC was not significant (P＞0.05),while the A1 of ASO or MMC was more than blank respectively(P＜0.05).The results of MVD were in accordance with the above results.Conclusion The injection of HSP70 mRNA ASO in tumor locally can inhibit neoplasm growth,and this effect might correlate with the inhibition of apoptosis and microvascular forming resulting from the ASO.

OBJECTIVETo investigate the main factors that influence measles morbidity and the genotype of measles virus, so as to provide evidence for scientific decision making to further control the prevalence of measles.

METHODA retrospective analysis included 182 children in Children's Hospital of Fudan University, diagnosed with measles from January 1, 2012 to December 31. The clinical and epidemiological characteristics, including the gender, age, the incidence of seasonal trends, measles vaccine vaccination history, contact history and other clinical manifestations, laboratory test results, and so on were analyzed. And the reverse transcription PCR (RT-PCR) was adopted to detect sputum specimens from suspected patients with measles,who were selected randomly,the sequence of the part of the PCR products was analyzed.

RESULT(1) Clinical and epidemiological data: Totally were 182 children with measles (125 males, 57 females) were enrolled into this study. The age of the patients ranged from 3 months to 89 months, 127 cases were younger than 9 months (69. 8%). The prevalence season was from April to August, while the peak month was April and May (22. 5%, 23. 1%). Among 182 hospitalized children, only 11 cases underwent measles vaccination (6. 0%), and among them 5 cases were within 2 weeks before disease onset. A total of 167 cases (91. 8%) had not been vaccinated, most of whom were immigrants, and the measles vaccination history of the remaining 4 cases were unknown. There was a positive correlation between the measles vaccination ratio in children of the floating population (8. 45%, 6/71) and the settled children (29.4%, 5/17, χ =8. 11 P =0. 004). In total, 24 cases (13. 2%) had definite measles exposure history, with 153 cases (84. 1%) of unknown origin,5 cases (2.7%) without any history of contact. (2) Clinical manifestations: All the 182 patients had fever (100%) and obvious rashes (100%), among them 145 cases had body temperature higher than 39 °C (79. 7%). The fever period ranged from 2 to 38 days. Among 182 hospitalized children,165 cases (90. 7%) had typical measles,17 cases had atypical measles. Among the 17 cases, two had severe measles, one had heterotypic measles. (3) The common complica tions: 96 cases had pneumonia (52. 8%), 80 had laryngitis (44. 0%), 38 had bronchitis (20. 9%),15 had hepatic dysfunction (8. 2%), 11 had myocardial damage (6. 0%), 3 had febrile seizures (1. 6%), and no patient had encephalitis. Of the 96 cases with pneumonia, 92 received sputum test; 38 were sputum culture positive (41%). The dominant pathogens were Streptococcus pneumoniae(11/38,29%), Haemophilus influenzae (6/ 38,16%), Moraxella catarrhalis (4/38, 11%), Escherichia coli (4/38, 11%), Candida albicans (4/38, 11%), Mycoplasma pneumoniae (4/38, 11%) and Staphylococcus aureus (3/38, 8%). (4) The H1a genotype was the only one genotype in the detected sequence of 54 measles virus strains.

CONCLUSIONMeasles was more often seen in the children under the age of 9 months from the floating population. The morbidity peak month was from April to May in Shanghai. The H1a genotype was the only one genotype. We should try to improve vaccination coverage rate in the children who are at the age for vaccination, so as to prevent measles outbreak.

The aim of this study was to investigate the effect of Compound Yihe Tea on improving insulin resistance in obesity mice. Thirty-two male C57BL/6J mice were randomly divided into 4 groups: the normal fat diet group(NFD group), high fat diet group(HFD group), Compound Yihe Tea low dosage group［20 mg/(kg ·d), YH-L group］ and high dosage group［40 mg/(kg ·d), YH-H group］. NFD group was given standard feed, and the remaining mice were administered with high fat diet. After 6 weeks, YH-H and YH-L groups were given Compound Yihe Tea for 6 weeks. Blood glucose was measured at week 11 and serum levels of total cholesterol(TC), serum triglyceride(TG), low-density lipoprotein cholesterol(LDL-C)and high-density lipoprotein cholesterol(HDL-C)were measured at week 12. Liver tissues were prepared for oil red O and HE staining. Immunohistochemical analysis was used to test the protein expression of GLUT4 in liver. Protein expressions of PI3K, Akt and GLUT4 in epididymis white adipose tissue(WAT)were tested by Western blot. The results showed that Compound Yihe Tea could effectively reduce body weights and the serum levels of TC, TG and LDL-C. Furthermore Compound Yihe Tea could improve the histopathological changes of liver, up-regulate the protein expression of PI3K, Akt and GLUT4 in epididymis WAT and the protein expression of GLUT4 in liver. Compound Yihe Tea can reduce the fat accumulation in liver tissue, improve the indexes of blood glucose and lipid levels, and improve insulin resistance via PI3K-AKT-GLUT4 pathway.

Methods Scorpions amplification refractory mutation system ( scorpions ARMS) fluorescence quantitative PCR was performed to investigate 205 driver gene mutation status in NSCLC in correlation with clinicopathological characteristics of the patients.Results Driver gene mutations were detected in 146 of 205 (71.2%) patients with NSCLC, including 81.7%( 138/169 ) adenocarcinomas, in which mutations of nine genes were found:EGFR (63.3%,107/169), KRAS (5.9%,10/169), PIK3CA (4.1%,7/169), ALK (4.1%,7/169), ROS1 (3.0%,5/169), RET (3.6%,6/169), HER2 (1.8%,3/169), NRAS (0.6%,1/169) and BRAF (0.6%,1/169).The frequencies of driver gene mutations were higher in adenocarcinomas, female patients and non-smokers (P<0.01, P=0.003, P<0.01, respectively).Driver gene mutation status showed no correlation with either the age or the clinical stage (P=0.281, P=0.490, respectively).However, EGFR mutations tended to occur in adenocarcinoma, female, non-smokers, and patients of≥62 years of age ( P<0.01, P<0.01, P=0.002, P=0.012, respectively) .The frequency of EGFR mutation was positively correlated with the tumor histology of lepidic, acinar, papillary and micropapillary predominant growth patterns.There was no relationship between EGFR mutation and the clinical stage ( P =0.237 ) .The frequency of KRAS mutation was higher in solid predominant and invasive mucinous adenocarcinomas ( P=0.015); that of PIK3CA mutation was higher in patients of ≥62 years of age, invasive mucinous adenocarcinoma and fetal adenocarcinoma ( P =0.015, P =0.006, respectively) .ALK, ROS1 or RET mutation positive NSCLC tended to occur in nonsmokers and have solid predominant tumors and invasive mucinous adenocarcinoma ( P=0.012, P=0.017 respectively).The frequency of EML4-ALK mutation was higher in the early stage patients with solid predominant tumors and invasive mucinous adenocarcinomas ( P=0.025, P =0.014, respectively ); that of ROS1 rearrangement was higher in invasive mucinous adenocarcinomas (P=0.049).NRAS, BRAF and HER2 gene mutations were infrequent and their clinical significance remained to be elucidated.Conclusions The relationship between mutations of well-known driver genes and clinicopathological characteristics in patients with NSCLC has diversity, the rate of mutations is higher in non-smoking female patients with adenocarcinoma.

Objective:To study the potential mechanism of Ganwei Baihe Decoction in the treatment of gastric ulcer (GU) based on bioinformatics and validate it through animal experiments.Methods:TCMSP, DisGeNET, and GeneCards databases were used to retrieved active components and action targets of Ganwei Baihe Decoction. After obtaining the intersection, protein interaction data of the intersection genes were obtained through the STRING database. A PPI network was constructed by Cytoscape 3.10.0 software and the key genes and key components were obtained. DAVID online analysis database was used for GO functional enrichment and KEGG pathway enrichment analysis of key targets. Animal experiments were used for verification. Totally 36 SD rats were divided into blank group, model group, Omeprazole group and Ganwei Baihe Decoction group according to the random number table method, with 9 rats in each group. After 7 days of gavage of the corresponding drugs to each group of rats, they fasted and but with water for 24 hours, and then re-gavaged once. After 1 hour of administration, a gastric ulcer rat model was prepared by gavage of 80 mg/kg of indomethacin. After 3 hours of administration, anesthesia was used to extract the sample. The expression level of Caspase-3 protein in the gastric tissue of rats was to be determined by Western blot method.Results:There were 234 effective active components with 290 targets in Ganwei Baihe Decoction, and 6 496 therapeutic targets for GU. 213 potential targets for GU were screened out. There were 437 GO function and 153 KEGG pathway enriched entries. Compared with the model group, the protein expression of Caspase-3 in the Ganwei Baihe Decoction group and Omeprazole group decreased ( P<0.05). Conclusion:The mechanism of Ganwei Baihe Decoction in treating GU may be through key components such as quercetin and β-sitosterol acting on key targets such as AKT1 and CASP3, regulating the Apoptosis pathway, PI3K-Akt signaling pathway, MAPK signaling pathway, etc. to exert inhibitory effects on apoptosis.

Objective To observe the expressions of serum insulin-like growth factor (IGF)- Ⅰ ,Ⅱ and IGF binding protein (IGFBP) 3, 5 and to explore the clinical significances in patients with clear cell carcinoma of kidney. Methods Enzyme-linked immunosorbent assay (ELISA) methods were adopted to examine serum expressions of IGF-Ⅰ , Ⅱ and IGFBP 3, 5 in 40 cases with clear cell carcinoma of kidney (renal carcinoma group) and 16 cases with hydronephrosis (control group) from May 2007 to December 2009. Results IGF- Ⅰ , Ⅱ and IGFBP 3,5 in renal carcinoma showed higher expressions before operation (985. 7 μg/L, 1154.0 μg/L,46.6 μg/L and 9.6 μg/L, respectively)than after operation (431.4 μg/L, 632.6 μg/L, 26.7 μg/L, and 6.7 μg/L, respectively, all P＜0. 05 ～0.01). There were no significant differences in those indexes between pre- and post- operation in control group (P＞ 0. 05). Conclusions There are high expressions of serum IGF-Ⅰ , Ⅱ and IGFBP 3, 5 in renal carcinoma patients, and IGF- Ⅱ has clinical significance in diagnosis.

Objective: To study the characteristics of lung adenocarcinoma driver gene variants detected by next generation sequencing (NGS) and quantitative fluorescence PCR. Methods: NGS was performed on 372 surgical resections from primary lung adenocarcinoma patients to detect 10 driver gene mutations, single-nucleotide variants(SNV), insertion/deletion and gene fusions; and quantitative fluorescence PCR were performed on 169 surgical resections from primary lung adenocarcinoma patients to detect nine driver gene hotspot mutations. Variants of VAF (variant allele frequency)≥1.0% were classified into 1 of 4 levels according to the guidelines and the precision oncology knowledge base of OncoKB, and the characteristics were investigated. Results: Sixty seven variants(leve1-4) were found by NGS, the positive rate of total mutations was 86.6% (322/372), in which variants at four levels were detected: levelⅠvariant, which was recognized as biomarker predictive of response to an FDA/NMPA approved drug in non-small cell lung cancer (NSCLC), was 71.2% (265/372);level Ⅱ variant, which was recognized as being standard care by the NCCN or other expert panels, was 3.0% (11/372); levelⅢA, a variant with compelling clinical evidence supports the biomarker as being predictive of response to a drug in this indication 3.0% (11/372); levelⅢB, a variant with compelling clinical evidence supports the biomarker as being predictive of response to a drug in another indication, was 4.3% (16/372); and level Ⅳ, a variant with compelling biological evidence supports the biomarker as being predictive of response to a drug, was 8.1% (30/372). The positive rate of unknown clinical significance and/or benign/likely benign variants was 18.8% (70/372). The positive rate of mutations detected by quantitative fluorescence PCR was 81.7% (138/169). Eighteen of the 20 samples showed concordance between NGS and quantitative fluorescence PCR. The two discordant cases could be due to the lack of coverage of two mutation sites in fluorescence PCR: EGFR c. 2571_2573delinsTCG(p. L858R), and HIP1-ALK_H19:A20 fusion. Conclusions Lung adenocarcinoma driver gene variants occur mainly in hotspot region, and NGS can comprehensively detect the driver gene variants of significant and potential clinical significance. NGS should be recommended when multiple genes need to be tested.
