Lung cancer is one of the commonest of malignant tumor in the world.It is a major threat to human health in China with highest morbidity and mortality.Steady increase in incidence rates have been observed worldwide in the last few decades in young patients,but previous studies have provided conflicting data about the clinical characteristics and prognoses of young patients with lung cancer.Consequently,we have difficulty in comparing their results with each other,as the cutoff ages defining"young"were different in each study.Therefore,this article focuses on the clinical characteristics and the different results of researches for the young patients with primary lung cancer.

Background Laser peripheral iridotomy(LPI) is used as the primary therapy for the eyes at risk of angle closure.But there are still 28% eyes with primary angle closure suspect occur angle closure within 2 years after LPI.It is necessary to explore the associated factors of the efficacy of LPI.Objective The aim of this study was to explore the changes of intraocular pressure(IOP) and anterior chamber angle in the fellow eyes of patients with unilateral acute attack of primary angle closure glaucoma (PACG) and analyze the relevant factors influencing the successful rate of LPI.Methods Eighty-seven fellow eyes received LPI from 87 patients with unilateral acute attack of PACG were included in this study and retrospectively analyzed.The IOP and gonioscopy were performed before and 1 week,3,6,9,12 months after LPI.Successful signs of LPI were defined as an IOP 6-21mmHg without any anti-glaucoma medication,none of glaucomatous neuropathy and the coincident visual field loss,and no need of additional glaucomatous medication or surgery.This study was approved by Ethic Committee of the First Hospital of Xinxiang Medical College,and written informed consent was obtained from each patient.Results Seventy-nine eyes of 79 cases finished the medical visit throughout the follow-up duration with the age 61.4±0.4 years and 33(41.8%) males and 46(58.2%) females.The mean IOP was lowed in various time points after LPI in comparison with before operation with the general difference among different time visiting groups(F=4.056,P＜0.01).Shaffer grade was increased in superior,temporal and nasal quadrants and significant differences were found between 1 week group,3 months group or 6 months group and before operation group (P＜0.05).LPI lessened the range of appositional angle closure (AAC) in postoperative 1 week group and 3 months group compared with pre-operative group (P＜0.05),but no statistically significant reduce was seen in range of AAC from 6 months through 12 months after LPI in comparison with pre-operation (P＞0.05).LPI was determined as successful in 61 cases (77.2%) during one-year fellow-up period.Several variables,such as preoperative IOP,Shaffer grade of each quadrant,mean Shaffer grade and the extent of AAC,were significantly different between LPI success and failure group(P＜0.01).Cox stepwise regression analysis found that the success rate was significantly associated with the extent of AAC (Wald=48.150,RR=1.963,P＜0.01) rather than pre-IOP,Shaffer grade of each quadrant,mean Shaffer grade,age and gender (P＞0.05).Conclusion LPI can widen the anterior chamber angle and low IOP in the fellow eyes of PACG attack eyes.The success rate of LPI is associated with the extent of pre-AAC,suggesting that it is necessary for LPI in consideration of the extent of pre-AAC.

Pseudomonas aeruginosa is one of the most common causes of nosocomial infection due to its intrinsic resistance to antibiotics. In the host,glutathione(GSH) ,one of the most important intracellular antioxidants,provides protection against high levels of oxidative stress. A decrease in GSH levels in tissues infected with P. aeruginosa has been observed while interactions between pyocyanin and GSH maybe partially attribute to P. aeruginosa infection. In this review,the relationship between GSH and the pathogenicity of P. aeruginosa has been discussed based on the author's own research results and the latest literature.

OBJECTIVETo explore effective approaches of treating elderly patients with distal tibiofibular fractures.

METHODSFrom August 2008 to October 2012,175 elderly patients with distal tibiofibular fractures were treated with locking compression plate (LCP) through anterior tibial. There were 112 males and 63 females with an average of 71.3 (ranged 60 to 83) years old. Of them,89 cases were treated by anterior tibial tension reduced incision with LCP,including 62 males and 27 females with a mean age of (71.8 +/- 6.4) years old. Eighty-six patients were treated by distal tibial incision with LCP,including 58 males and 28 females with a mean age of (70.3 +/- 6.7) years old. Swelling time, operation time, intraoperative blood loss, hospital stay, healing time, complications and AOFAS scores were compared between two groups after operation.

RESULTSSwelling time in anterior tension reduced incision with LCP and distal tibial incision with LCP was (5.6 +/- 1.3) and (9.7 +/- 2.1) days, healing time was (4.2 +/- 1.4) and (5.4 +/- 1.9) months,and complications were found 3 in tension reduced incision and 10 in distak tibial incision respectively;and all data shown statistically significant differences between two groups (P < 0.05). At 12 months after operation,AOFAS score was 89.0 +/- 9.7, 87.9 +/- 9.4; and there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONTension reduced incision through anterior tibial combined with locking compression plate fixation in treating elderly patients with distal tibiofibular fractures can provide good clinical effects with quick fracture healing and low complications.

Objective To screen for differential expression of genes in bone marrow mesenchymal stem ceils (MSCs) stimulated by electromagnetic fields (EMFs) and to study the mechanism of differentiation of the bone mar- row MSCs induced by EMFs.Methods Mouse bone marrow MSCs were isolated and cultured in vitro.The third- passage cells were stimulated by EMFs,then the total RNA was extracted,purified to cDNA and reversely transcribed to yield a cRNA probe.The cRNA probes from stimulated and control cells were labelled with Cy5 and Cy3,respec- tively.The two samples were hybridized with a mouse oligo microarray,and the hybridization signals were scanned. The reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the interesting genes:Duspl and Rabl.Results A total of 153 differentially expressed genes were found comparing the stimulated group and the control group.There were 74 up-regulated genes and 79 down-regulated genes in the stimulated group.Semi-quantita- tive RT-PCR confirmed that the Duspl and Rabl mRNA expression levels of the stimulated group were up-regulated. Conclusion The gene expression profiles of the bone marrow MSCs were altered after EMF exposure.The genes are involved in cell proliferation and differentiation,transcription control,metabolism and response to stress.These re- sults provide deeper insight into the mechanism of differentiation of the bone marrow MSCs.

Objective To study the effects of 50 Hz magnetic fields on the in vitro proliferation of human osteosareoma cell line MG-63 with different cell densities.Methods Four different magnetic intensities(1 mT, 2 mT,3 roT,4 mT)were used to stimulate the cells,and the experiment was repeated with different cell densities. The method of MTT was employed to evaluate the level of proliferation.Results Fifty Hz magnetic fields signifi- cantly affected the level of proliferation of human osteosareoma cell line MG-63,and the 2 mT intensity exerted the greatest influence on it.The effects of the magnetic field differed with different cell densities.Conclusion The effect of 50 Hz magnetic fields on the in vitro proliferation of human osteosarcoma cell line MG-63 was not only relat- ed to the magnetic intensity,but also the cell density,
