Objective:To assess the role of EGFR mutations on pemetrexed response in patients with advanced lung adenocarcino-ma. Method: Forty pulmonary adenocarcinoma patients with evaluable lesions were retrospectively screened .They had been treated with pemetrexed-included chemotherapy and had EGFR gene test results. The evaluation endpoints were overall response rate,disease control rate and progression free survival. Result:No significant statistical difference was seen in overall response rate(ORR) (44.4%VS 31.8%, respectively) and disease control rate(DCR) (88.9%VS 81.8%, respectively ) between EGFR wild group and EGFR muta-tion group, but patients in EGFR wild group had longer progression free survival(PFS) ( 8.9 months VS 5.3 months;P=0.046). Conclu-sion:EGFR mutation status can influence the efficacy of pemetrexed.

Objective To compare the clinical effect of three kinds of gastric canal inserted method on patients with endotracheal intubation.Methods Two hundred and sixty-one cases of patients with endotracheal intubation were divided into group A(conventional group),B(inserting gastrotuhe by a guide-wire in it),C (pulling the tracheal under calm state),with each group of eighty-seven cases.The intubation successful rate,the time of gastric canal insertion,HR and SpO2 before and after inttthation,and the choking and blcoding occurrence during intubation were observed and compared.Results The intubation successful rate showed significantly higher in the group B(83.91%)than in the group A(70.11%,P＜0.05),and significantly higher in the group C(98.85%)than in the groups A and B(all P ＜ 0.01).In the time of gastrotuhe insertion,significantly quicker in the group B(43.25±5.56s)than in the group A(55.30±6.20)s(P ＜0.01),and significantly quicker in the group C(27.75±4.16)s than in the groups A and B(all P ＜ 0.01);In the total time of whole operation,significantly quicker in the group C(103.16±5.36)s than in the groups A and B(111.45±5.85 s、115.35± 5.25 s,all P ＜0.01),and significantly slower in the group B than in the group A(P ＜0.01).Before and after gastrotube insertion,there was no significant difference on HR in groups B and C(all P＞0.05),in the group A HR was obviously increased(P ＜0.05);while SpO2 there was no significant difference in group C,and the remarkably decreased in groups A and B(P ＜ 0.01,P ＜ 0.05).During the gastrotube insertion,The choking and blcoding occurrence in the group C(2.30%、O)was significantly lower than in the groups A(13.79%、9.20%)and B(8.05%,5.75%)(P＜0.01,P ＜ 0.05),and there was no significant difference in groups B and A(all P ＞0.05).Conclusions It shows higher accurate and less side effect for the endotracbeal intubation patients undergoing gastrotuhe insertion by pulling the tracheal under calm state.

OBJECTIVETo evaluate the relationship between sperm motility parameters and sperm morphology.

METHODSSeven hundred and eighty-three semen samples were tested. Sperm motility parameters were analyzed by computer-aided sperm analysis (CASA) , and sperm morphology assessed by automated sperm morphology analyzer (ASMA). The cases were classified based on the World Health Organization criteria. Morphologically 241 of the samples were normal and the other 542 abnormal.

RESULTSVCL, WOB, VAP of the morphologically abnormal group were significantly higher than those of the normal group (P < 0.05, P < 0.001), while MAD, LIN, STR of the abnormal group were significantly lower (P < 0.05, P < 0.001). There were significant positive correlations between the morphologically normal sperm rates and MAD, LIN, WOB, STR, and a significant negative correlation between the morphologically normal sperm rate and ALH.

CONCLUSIONMorphological abnormality of sperm is often accompanied with weak motility, which is probably attributed more to some factors that coact on both sperm motility and morphology than to the influence of sperm morphological abnormality on sperm motility.

Objective To investigate the relationship between nuclear factor kappa B(NF-κB) and matrix metalloproteinase-9 (MMP-9) mRNA in human umbilical vein endothelial cells(HUVECs) stimulated by the serum from children with coronary artery lesions of Kawasaki disease (KD).Methods HUVECs were cultured and were divided into 4 groups:normal serum group,general fever group,Non-CALs group and CALs group.Co-Immunoprecipitation (ChIP) was used to detect the relationship between NF-κB and MMP-9,and RT-PCR was used to detect the mRNA level of MMP-9.Results Compared with control groups,NF-κB p65 could bind the promoter of MMP 9 in HUVECs cultured with 10 ％ serum from KD patients with coronary artery lesions.The mRNA level of MMP 9 was also up-regulated.Conclusion NF-κB p65 can promote the transcription of MMP-9 in HUVECs induced by the serum from KD patients with coronary artery lesions.

OBJECTIVETo evaluate the 3-D position changes of periorbital structures after midface distraction osteogenesis in patients with Crouzon syndrome.

METHODSThe CT data of 8 cases who had accepted the midface distraction osteogenesis following Le Fort III osteotomy were retrospectively analyzed. The patients were averagely 11.9 years old, and the CT was performed before and one year after operation. After 3-D image reconstruction, a right-hand coordinate system based on the preoperational Frankfurt Plane was then established. The pre- and post-operative positions of the superior orbit point (SOr), inferior orbit point (IOr), median orbit point (MOr), lateral orbit point (LOr), anterior ocularis point (AO), ocularis eyeball point (PO) and the four insertion ocularis rectus were documented and compared. The positions of these marked points in normal controls were also documented and compared with those in patients.

RESULTSAfter midface distraction osteogenesis, the position of AO was not changed significantly on the y-axis and z-axis, but the distance between two AO points on x-axis was reduced by 3.40 mm; IOr moved averagely 12.24 mm on y-axis and 4.25 mm on z-axis, MOr moved averagely 10.11 mm on y-axis and 2.80 mm on z-axis, LOr moved averagely 9.86 mm on y-axis and 2.31 mm on z-axis. The Inferior Rectus attachment moved averagely 3.63 mm on y-axis and 2.98 mm on z-axis. No other significant change was observed on other marked points.

CONCLUSIONSMidface distraction osteogenesis following Le Fort III osteotomy can significantly move the medial, lateral and inferior peri-orbital bone structure anteriorly and inferiorly. The eyeballs have no markedly sagittal position changes after distraction except slight medial, downwards movements and anterior-upwards rotations.

OBJECTIVE: To explore the molecular basis for a pedigree affected with spondyloepiphyseal dysplasia congenita (SEDC). METHODS: The proband was subjected to whole exome sequencing. Suspected variant was verified by Sanger sequencing. RESULTS: All patients from the pedigree were found to carry a novel missense variant c.1394G>C (p.Gly465Ala) of the COL2A1 gene. The variant was not reported previously. Provean, Polyphen-2 and Mutation Taster software predicted that the variant is highly likely to be pathogenic. CONCLUSION The c.1394G>C (p.Gly465Ala) variant of the COL2A1 gene probably underlies the SEDC in this pedigree.

To investigate the expression of nucleolar and spindle?associated protein 1 (NUSAP1) in non?small cell lung cancer ( NSCLC) and analyze its relationship with the prognosis of NSCLC patients. Methods Real?time fluorescent quantitative PCR and immunohistochemical staining were performed to determine the expression of NUSAP1 in NSCLC tissues and adjacent tissues collected from hospital. The relationship between NUSAP1 expression and prognosis of NSCLC patients was analyzed by online database. Results The expression level of NUSAP1 mRNA in tumor tissues was significantly higher than that of adjacent tissues (P＜0.05). The high expression rate of NUSAP1 protein in NSCLC tissues was 58.0%( 29／50), significantly higher than 22.0%( 11／50) of adjacent tissues ( P＜0.05). The high expression of NUSAP1 protein in NSCLC tissues was closely correlated with tumor size, lymph node metastasis and TNM stage ( P＜0.05), but was not related to age and gender. The data showed that the expression level of NUSAP1 mRNA was inversely associated with the overall survival ( OS) of NSCLC patients ( P＜0.001). The expression of NUSAP1 mRNA was significantly correlated with the pathological grade, clinical stage, gender, chemotherapy, smoking history, and histological type of NSCLC patients (P＜0.05). Conclusions The expression of NUSAP1 is up?regulated in NSCLC, which is correlated with the growth and development of NSCLC and prognosis of the patients. These results indicate that NUSAP1 can be used as a potential prognostic marker for NSCLC.
