Peripheral T cells are closely related to nature killer( NK)cells,and share some immunophenotypic and functional properties with NK cells.Peripheral T-cell and NK cell lymphomas are heterogeneous groups of lymphomas,and the subgroup classification is complicated.Currently,the pathogenetic molecular lesions remain not to be deciphered for most entities.However,novel insights into the features of angioimmunoblastic T-cell lymphoma displaying correlation with normal helper T cells,the gene of anaplastic large cell lymphoma,and potential therapeutic biomarkers,have been gained from molecular technology application.

A total of 122 patients with acute left ventricular failure from January 2011 to December 2013 at our hospital were recruited and divided randomly into control group (n =62) and observation group (n =60).Control group received conventional therapy and Bi-level positive airway pressure (Bi-PAP) was added along with conventional therapy for observation group.And 12 and 8 patients died in control and observation groups respectively within 24 h after treatment and there was no statistical difference.The BNP levels of the control group pre-treatment and at 1 h and 24 h post-treatment were (1 040 ± 315),(995 ± 245) and (570 ± 164) ng/L.The BNP levels of observation group pre-treatment and at 1 h and 24 h posttreatment were (1 080 ±209),(995 ±245) and (490 ± 138) ng/L.BNP of observation group at 1 h and 24 h post-treatment decreased significantly compared with that pre-treatment and control group (P ＜0.01).Only at 24 h post-treatment,the BNP level of control group decreased significantly compared with that pretreatment (P ＜ 0.01).

Study of the strategic objectives chosen by hospitals from the perspective of stakeholders is now under the spotlight of researchers at large. To identify whether there exist differences in strategic objectives among various groups in the hospital and probe into the causes, the author called into play the competing values framework as the analysis tool. An evidenced-based study on public hospitals in Hangzhou identified marked differences on choices of strategic objectives among various internal stakeholders in the hospital For example, hospital administrators tend to focus on internal control, while medical doctors tend to focus on interactions between the hospital and the external environment. On this basis, further studies are proposed.

Objective To study the differences of suicide mortalities of the urban and rural residents in Liaoning Province. Methods The 1999-2003 suicidal data form Liaoning CDC were analyzed. Results Average suicide mortality was 6.28 for city and 18.34 for country per 100 000 persons in Liaoning Province during 1999 to 2003. The rural suicide mortality was higher than urban (?2=1626.74, P

Background Application of available technology and objective indexes are very important for the early diagnosis,monitoring and therapeutic evaluation of primary open angle glaucoma (POAG).Many studies have determined retinal damage in structure and function in POAG.However,the study on the association of structural damage and functional abnormality in early POAG is still lack.Objective This study was to evaluate the relationship between structural and functional changes of retina in early stage of POAG.Methods A prospectively pilot study was performed under the approval of Ethic Committee of Shenzhen Eye Hospital from January 2011 to June 2013.Based on Helsinki Declaration,written informed consent was obtained from subject prior to entering the cohort.Ninety-five eyes of 95 POAG patients were included as the study group,and 41 eyes of 41 non-glaucoma subjects were enrolled at the same period as controls.The structural parameters of retinas were measured using RTVue-100 OCT and Cirrus HD-OCT respectively,including macular ganglion cell complex (GCC)-Avg thickness and peripapillary retinal neural fibril layer (RNFL)-Avg thickness;and the functional parameters of retinas were obtained by Humphrey visual filed analyzer and RETI scan 3.15 system respectively,including MD of visual field and PhNR of flash electroretinogram (F-ERG).The associations between the GCC or RNFL thickness and M D or amplitude of PhNR were evaluated by linear and curvilinear regression models.Results The MD,GCC-Avg,RNFL-Avg and PhNR amplitude were (-0.68±1.72)dB,(97.17± 4.82)μm,(102.51±8.74) μm and (49.61±11.01)μV respectively in the control subjects,and those in the POAG patients were (-10.82±9.87) dB,(75.07±12.29) μm,(69.09±12.96) μm and (28.38± 11.52) μV,showing significant differences between them (t =6.549,11.118,-15.061,9.956,all at P=0.001).The curvilinear regression model appeared to better describe the relationship between GCC thickness and MD (R2 =0.595,F=97.089,P＜0.001) ;while a linear regression model seemed to be better fit for the relationship between GCC thickness and amplitude of PhNR (R2=0.437,F=103.413,P＜0.001).RNFL thickness analysis showed the similar regression models with MD and amplitude of PhNR as GCC thickness,but R2 values were higher between the RNFL thickness and MD (R2 =0.606,F =101.666,P＜0.001) or amplitude of PhNR (R2 =0.454,F=54.983,P＜0.001).Conclusions Both GCC thickness and RNFL thickness show a curvilinear relationship with MD and a linear relationship with amplitude of PhNR.Goodness-of-fit of RNFL thickness is superior to GCC thickness.

Objective To investigate the clinical allocation significance of modified early warning score (MEWS) for emergency department patients.Methods MEWS of 1 069 patients in medical emergency department from August 2011 to March 2013 were recorded and analyzed.The admitted differences of MEWS among in intensive care unit(ICU),general wards and emergency transfer observing patients were compared.Results The MEWS of emergency department patients were different.The deaths and ICU patients together as ICU patients,MEWS ≥ 7 scores the proportion of patients admitted to ICU were significantly higher than those of MEWS 3-6 scores and 0-2 scores [37.8％(14/38) vs.2.1％ (6/289) and 0.1％(1/742)](P＜0.01).Conclusion MEWS provides an objective allocation basis for emergency department patients.

Objective To analyze the influences of lacrimal secretion and tear film after interferon-alpha therapy in patients with chronic viral hepatitis.Methods Sixty patients with chronic viral hepatitis who would accept the interferon-alpha therapy,including 30 cases of hepatitis B and 30 chronic viral hepatitis C,visited our department of ophthalmology and were enrolled in this study.All cases received eye examination,including medical history,slit lamp examination,corneal fluorescein staining ( FL) ,tear film break-up time ( BUT) and schirmer test before inter-feron-alpha therapy and two months after the therapy.Results In the 60 cases of chronic viral hepatitis,there were 19 dry eye cases (31.67%) and 41 non-dry eye cases (68.33%).In dry eyes group,9 of them (47.37%) were hepatitis B patients and 10 of them were hepatitis C patients (52.63%) .There was significant difference in FL grade (t=-5.288,P<0.05),BUT (t=5.799,P<0.05),Schirmer Ⅰ(t=5.319,P<0.05) test in hepatitis B before and two months after interferon-alpha therapy.Statistical significance had been found before and two months after therapy in FL grade (t=-9.103,P<0.05),BUT (t=5.682,P<0.05),SchirmerⅠtest (t=4.592,P<0.05). The incidence of dry eye syndrome in hepatitis B patients increased from 26.70%to 53.30%two months after treated with interferon-alpha,while the incidence of dry eye syndrome in hepatitis C patients increased from 33.30% to 60.00% two months after treated with interferon-alpha.Conclusion Dry eye syndrome is one of common complica-tions in patients with chronic viral hepatitis.Interferon-alpha therapy would influence the lacrimal secretion and dam-age tear film,which increased the dry symptoms in patients.We should pay attention to the side effects of interferon-alpha therapy.

Objective To investigate the trends in and characteristics of syphilis epidemiology in China,and to provide a scientific basis for the development of control strategies.Methods An epidemiological study was performed on syphilis cases reported from 31 provinces,autonomous regions and municipalities between 2000 and 2013.Results The reported syphilis incidence increased yearly from 6.43 per 100 000 person-years in 2000 to 32.86 per 100 000 person-years in 2013,with an average annual growth rate of 13.37％.Syphilis was reported in most (99％) counties/districts in China mainland except for a few remote mountain areas,with a significant difference in the incidence of syphilis between different regions.The regions with a high incidence of syphilis included minority areas in Northwest China (Xinjiang,Qinghai and Ningxia),Minjiang River area,Yangtze River Delta (Zhejiang,Shanghai),Zhujiang River Delta (Guangxi,Guangdong),etc.There had been a rapid increase in the incidence of syphilis in some regions previously reported to have a low incidence (such as Guizhou,Shaanxi,Henan,etc).Among the reported cases,female patients predominated with an average male/female ratio of 0.92 ∶ 1.The incidence of syphilis was highest in the age group of 20-39 years,but increased yearly by more than 30％ in the population aged ＞ 60 years.Of 20 occupations,peasant workers accounted for the highest proportion (31.56％) of syphilis cases,and retired population showed the most rapid increase by about 27.35％ per year.The constituent ratio of primary and secondary syphilis in all the syphilis cases had declined yearly,while that of latent syphilis increased by more than 50％ after 2010.Conclusions Syphilis remains a major public health issue in China,and measures based on the epidemiological features are urgently needed to effectively control epidemic syphilis.
