Objective To explore the correlation factors of hospital stay and hospitalization costs among patients with acute ischemia stroke (AIS). Methods The clinical data of the patients with first diagnosis of AIS at Peking University Third Hospital in China from January 1 , 2012 to December 31 , 2012 were retrospectively analyzed to investigate the correlation factors of hospital stay and hospitalization costs using univariate analysis and multiple regression analysis. Results The study involved 496 patients, with a mean age of 63.38 years (range:26~88 years). Multivariate regression analysis showed the significant impact factors for LOS were age, pneumonia, the total score on NIHSS, medication for secondary prevention and stroke subtype. The significant impact factors for cost of hospital stay were payment method, stroke subtype, age, the total score on NIHSS and medication for secondary prevention. Conclusions Age, pneumonia, the total score on NIHSS, stroke treatment and its subtypes are the significant impact factors affecting hospital stay. Payment method, stroke subtype, age, the total score on NIHSS and medication for secondary prevention are the significant impact factors affecting costs of hospitalization.

BACKGROUND:Knee osteoarthritis and rheumatoid arthritis are common arthritis in the knee.In late stage of arthritis,severe deformation and activity obstacle are found,which require total knee replacement.The total knee replacement not only can significantly relieve symptom,but also correct deformation and improve joint function.OBJECTIVE:To summarize classification of knee joint,techniques of knee replacement surgery and complications following replacement.METHODS:We retrieved Vip Database (http://www.cqvip.com) for titles and abstracts with the key words of "knee replacement,prosthesis,complication".Articles concerning clinical application of knee prosthesis were included.Articles in the same field that published recently or in authorized journals were included.A total of 20 literatures were included for review according to inclusion criteria.RESULTS AND CONCLUSION:Various artificial total knee prostheses were used in different patients in accordance with patients' condition,joint limitation degree,fixation method and meniscus function.Indication of different knee prostheses depends on bone and soft tissue of the knee,and quality and status of knee ligament,joint deformation and destruction degree of articular cartilage are responsible for the choice of prosthesis.Thrombosis of deep veins of the lower limb,pulmonary embolism,infection surrounding the prosthesis and prosthesis loose are common complications in joint replacement.

Objective To explore clinical effect of nedaplatin combined gemcitabine on chemotherapy of advanced non-small cell lung cancer (NSCLC),and to observe the prognosis and complications of these patients. Methods 106 patients with advanced NSCLC were selected,they were randomly divided into the treatment group and the control group with 53 cases each group,according to the single and double of order registration number.The con-trol group were given cisplatin combined gemcitabine chemotherapy,the treatment group were administrated nedaplatin combined gemcitabine chemotherapy,three weeks repeat.The treatment effect was estimated after two cycles of chemo-therapy,and progression-free survival ( PFS) ,patients quality of life with KPS after treatment,and the adverse reac-tions were assessed.Results The disease control rates (DCR) of the treatment group was 77.36% (41/53),the control group was 71.70%(38/53),there was no statistically significant difference (χ2 =2.46,P>0.05).PFS of the treatment group were (4.26 ±0.38) months,the control group was (3.72 ±0.30) months,there was no statisti-cally significant difference (t=2.94,P>0.05).KPS of the treatment group was (74.48 ±4.04)points,which was higher than (69.76 ±3.28)points of the control group,the difference was statistically significant (t =7.33,P<0.05).The total adverse reaction of the treatment group was 81.13%(43/53),which was lower than the control group 90.57%(48/53),the difference was statistically significant (χ2 =7.61,P<0.05).Conclusion There is preferably clinical effect of nedaplatin combined gemcitabine treatment of NSCLC,the adverse reactions was lower sig-nificantly,the patients prognosis is good,and which is worth clinical promotion.

In order to improve the teaching effect ,we tried to use problem-based learning(PBL)in combination with traditional teaching method to teach medical students in clinical probation of Gynecology and Obstetrics. The results showed that PBL in combination with traditional teaching method was possible and effective. PBL was helpful to cultivating the clinical consciousness and comprehensive diathesis of medical students.

Objective To descript the current situation and to analyze the impact factors of the stigma among the community women with urinary incontinence in Jinan.Methods This was a crosssectional survey by purposive sampling.506 women with urinary incontinence from 3 communities in Jinan were measured by the International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF) and the revised version of the Social Impact Scale(SIS)in order to get the information about the urinary incontinence type,severity degree and the stigma.Results The participants' total score of the SIS was (39.62±8.10) points and the score index was 55％.Score index of three subscale including social isolation,social exclusion and inner sense of shame were 58％,45％,70％; age and severity degree of urinary incontinence were independent factors and totally accounted for 14.0％ of the variance in stigma.Conclusions It suggested that,to make patients drop the cognitive errors about being incontinence,then decrease the stigma and improve the quality of life,the Health Care Sector should positively broadcast the relative knowledge of urinary incontinence and encourages patients to seek help,screen,diagnose,and get treatment earlier,and complete the tertiary prevention.

Objective To evaluate the killing effect and the uptake of 125I-UdR on human lymphoma Raji and Daudi cell lines. Methods The amount of 125I-UdR in the cells and cell nuclei were determined after incubation of different time in RPMI 1640 culturing medium containing different concentrations of 125I-UdR. The killing effects of 125I-UdR on Raji and Daudi cell lines were estimated through MTT assay and cell cycle was analyzed by propidium iodide (PI) staining. Results The amounts of 125I-UdR in Raji and Dandi cells and cell nuclei were much higher than that of Na125I(P < 0.05). The amounts of 125l-UdR in Raji and Daudi cells were 14414±95 and (6916± 53.69) Bq/106 cell when the concentration was 100 kBq/ml. The amounts of Na125I were 68± 3.8 and (324±32.8) Bq/106 cell. The uptake of 125I-UdR in Raji and Daudi cells and cell nuclei increased with the 125I-UdR concentration and incubated time. The cell surviving fractions of 125I-UdR groups was much lower than that of Na125I groups (P < 0.05). When the concentration was 500 kBq/ml and incubated time was 48 hours, the Raji and Dandi cell surviving fractions of125I-UdR groups were (19.78 ± 1.39)% and (43.17 ± 2.69) % ;those of Na125I groups were (79.10 ± 1.79) % and (80.36 ± 6.12) %. The surviving fractions of 125I-UdR groups reduced with the 125I-UdR concentration. Conclusions 125I-UdR can be specially ingested by Raji and Daudi cells and incorporated into DNA, then the cells will be killed. The uptake of 125I-UdR is dose and time dependent.

This study is to report the preparation of complexes of Ad5 and anionic liposomes (AL-Ad5), the amplification of adenoviruses with enhanced green fluorescent protein (eGFP) reporter gene performed by HEK 293 cells, the adenoviral vectors purified by cesium chloride gradient centrifugation, and the titer of adenovirus determined by cytopathic effect (CPE) method, hexon capsid immunoassay and quantitative-PCR (Q-PCR), separately. The prescription and experiment conditions were optimized by central composite design (CCD). The complexes of Ad5 and AL-Ad5 were formulated by the calcium-induced phase change method. The morpholopy, particle size and zeta potential were detected by dynamic light scattering (DLS) and transmission electron microscopy (TEM), respectively. Additionally, the bicolourable fluoresce-labeled complexes (F(labeled)-AL-Ad5) were prepared and their intracellular location in MDCK cells was detected by confocal laser scanning microscopy (CLSM). The results indicate that the complexes of AL-Ad5 exhibited a uniform distribution with a particle size of 211 +/- 10 nm and a zeta potential of -41.2 +/- 2.2 mV. The result of CLSM demonstrates that the intracellular location of red fluoresce-labeled adenovirus was consistent with that of green fluoresce-labeled liposomes suggesting that the naked adenovirus was well encapsulated by the anionic liposomes in complexes of AL-Ad5.

Radiation therapy is one of the important comprehensive treatment strategies for thoracic neoplasms,but it also can cause radiation-induced heart disease (RIHD) which can affect the quality of life and even endanger the lives of patients while killing tumor.With the development of comprehensive treatment for cancer,the patients achieve better survival outcomes.And the study reported about RIHD increased as well,which made RIHD became an important complication of thoracic neoplasms' treatment.Though modem radiotherapy techniques and new therapeutic principles have significantly made the incidence of RIHD decreased,the harm of RIHD should not be ignored.In this article,we review the research progress of RIHD.
