Background:Alcohol consumption and some other dietary habits are thought to be associated with lung cancer ***,the effects of these habits on lung cancer prognosis have been studied *** purpose of this study was to address these gaps in ***:We studied a cohort of 1052 Chinese men in Hong Kong who were diagnosed with primary lung *** proportional hazards models were used to determine the prognostic values of consumption of alcohol,fresh fruits or vegetables,meat,and fried or preserved ***:Compared with never drinkers,men who drank alcohol 1-3 days per week had a more favorable lung cancer prognosis(hazard ratio[HR]:0.82,95%confidence interval[CI]0.68-0.97);however,this survival advantage was not significant in men who drank alcohol more frequently(HR:0.91,95%CI 0.73-1.14).Compared with men who consumed preserved or fried food only occasionally,men who consumed these foods frequently had a higher risk of lung cancer mortality(HR:1.20,95%CI 1.00-1.42).Conclusions:Occasional consumption of alcohol was a favorable survival factor for Chinese men with lung ***,this survival benefit did not exist for frequent drinkers of *** men with lung cancer who were frequent consumers of fried or preserved food had a worse prognosis than those who consumed these foods only occasionally.

Subfertility can be caused by acquired or genetic factors. Y chromosome microdeletion is one of the genetic factors associating with male infertility.1 Azoospermia factors (AZFa, AZFb and AZFc) have been mapped to different subregions in Yq11.2 So far, two gene families, RNA-binding motif (RBM) and deleted in azoospermia (DAZ) from interval 6, were proposed as candidate spermatogenesis genes for AZF.3,4 Recent studies demonstrated that microdeletions were detected at a frequency of 5% to 18% in the AZF region of oligospermic and azoospermic men.5-7 With the development of assisted reproductive technologies, particularly intracytoplasmic sperm injection (ICSI), these men can now father a child and the genetic abnormalities in defective spermatozoa could be transmitted to future offspring. To examine the possible transmission of the Y-chromosome microdeletion to the offspring via ICSI treatment, we performed both cytogenetic and molecular analyses of the Y chromosome on both an infertile patient with Y chromosome microdeletion and his offspring.

三相电压源型并网换流器由于含有大量电力电子开关器件及相应控制环节,是一种强非线性系统。在交直流混合系统中受到电网侧故障或直流侧负载变化等扰动影响,大容量换流器将产生复杂的响应行为,给电网带来难以预计的影响。文中考虑电网中三相电压暂降的典型故障,基于平均模型分析了三相电压源型换流器电流环的非线性特性。在此基础上,根据李雅普诺夫稳定性判据分析了故障前后换流器的稳定性,并以故障深度和故障持续时间为指标对换流器故障耐受能力进行评估。最后,通过并网系统的逐周期仿真验证了理论分析和计算的有效性。

Primary squamous cell carcinoma (SCC) of the liveris rare. Totally nine such cases have been reportedin the literature. Primary SCC of the liver has beenreported to be associated with hepatic teratoma,hepatic cyst, or hepatolithiasis. Complete remission ofpoorly differentiated SCC of the liver could be achievedby systemic chemotherapy followed by surgery orremarkably respond to hepatic arterial injection of lowdose chemotherapeutic drugs. Here we report the fi rstcase of primary SCC of the liver presenting as a solidtumor and receiving successful hepatic resection with9-mo disease free survival.

发光二极管(light-emitting diode,LED)的伏安特性易受温度影响,且个体间存在差异,当多条LED支路并联连接于同一电压源时,会出现不均流现象。电流大的LED支路老化加速,光效衰减,甚至过早熄灭,严重影响了LED照明的可靠性。针对此问题,提出一种最小导通电流幅值反馈控制的脉宽调制(pulse width modulation,PWM)均流电路,该电路在常见的PWM均流基础上,自动调整LED支路的供电电压,使得LED支路中存在至少一条支路的均流占空比为1,其他支路的占空比尽可能大,有效提高LED光源的发光效率。此外,在该均流电路上,可容易实现LED支路的独立调光,无需增加电路和成本。最后,以Buck变换器驱动3条LED支路为例,搭建实验样机。实验结果证明了所提出的均流电路可有效实现LED支路均流,提高LED发光效率,并具有独立调光功能。

Although declining in the US due to restrictions of asbestos exposure, malignant pleura/mesothelioma （MPP） remains a very serious thoracic malignancy that is rising in incidence worldwide （1）. Trirnodality therapy with chemotherapy and radiotherapy combined with extrapleural pneumonectomy （EPP） has gained acceptance given the acceptable mortality rate （〈5%） and long term survival reported in patients with epithelial histology, negative margins, and no extrapleural lymph node involvement after trimodalitv treatment （2）.
