Objective To analyze the relative factors for the prognosis in elderly patients with stroke,and provide theoretical basis for improving prognosis.Methods 188 elderly patients with stroke were treated in our department from Jan.2011 to Nov.2013,and clinical data was analyzed.The prognosis and relative risk factors for stroke were statistically analyzed.Results 99 cases had good prognosis,89 cases had poor prognosis,and the recovery rate were 52.7％ (99/188) and 47.3％ (89/188) respectively.The age was older in group of good prognosis than in group of poor proghosis (t=1.7930,P＜0.05).Univariate analysis showed that the age,position of cerebral infarction,size of lesions,hypertension,diabetes,drinking and smoking were associated with the prognosis of stroke (t=1.7930,x2 =8.6473,15.046,13.1334,4.1536,5.7004,5.9043,respectively,all P＜0.05),while the prognosis was not associated with gender,a family history of stroke,hyperlipidemia and heart disease.Multivariate logistic regression analyses revealed the prognosis of stroke was related with risk factors of age (OR=1.072),size of the lesion (OR=3.481),hypertension (OR=2.034),diabetes (OR=1.631) and smoking (OR=3.144).Conclusions It is beneficial to the prognosis of patients with stroke to stop bad habits and to treat hypertension and diabetes actively.

OBJECTIVETo search for the optimal strategies for sperm collection from the patient with temporary penile erectile dysfunction (ED) on the day of oocyte pick-up ( OPU) in in vitro fertilization embryo transfer (IVF-ET).

METHODSWe retrospectively analyzed 93 cases of temporary ED on the OPU day of IVF-ET from January 2011 to May 2014, with fresh semen for 45 cases (group A), cryopreserved sperm before oocyte retrieval for 30 cases (group B), and frozen oocytes for 18 cases (group C). Group A was again subdivided into A1 (n = 18) and A2 n = 27) , the former intervened with oral sildenafil while the latter left untreated. We compared the rates of fertilization, high-quality embryo, and pregnancy among different groups.

RESULTSNo statistically significant differences were found among groups A, B and C in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and rates of cleavage, or in the percentages of normal fertilization (80.78% vs 80.43% vs 84.77%), high-quality embryo (53.27% vs 52.97% vs 47.69%) and pregnancy (60.00% vs 56.77% vs 44.44%) (all P > 0.05). The rate of 3PN was markedly lower in group C (0.63%) than in A (9. 61%) and B (4.34%) (P < 0.05). There were no significant differences between groups A1 and A2 in the age of the males and females, duration of infertility, numbers of obtained and mature oocytes, and the rates of fertilization, cleavage, high-quality embryo, and pregnancy (all P > 0.05).

CONCLUSIONOn the OPU day of IVF-ET, oral sildenafil can help temporary ED men to achieve penile erection and ejaculation without affecting the outcomes of assisted reproduction. Cryopreserved sperm can be used in case of predicted temporary ED and frozen oocytes can also be employed if sperm retrieval fails. However, to avoid puncture injury to the epididymis or testis, fresh semen should be the first choice.

Objective To investigate the effects of partial body weight supported treadmill training (BW- STT) on post-stroke depression (PSD) and on patients' quality of life.Methods Sixty patients with PSD were re- cruited and divided into a training group (n=30,male 17,female 13) and a control group (n=30,male 16,fe- male 14).All patients were treated with routine internal medication and rehabilitation.The patients of the training group also received BWSTT in addition to their routine treatment.All patients' neurological impairment was evaluated using the Modified Edinburgh-Scandinavian Stroke Scale (MESSS).The Hamilton depression scale (HAMD) was used for evaluating the degree of depression.The Fugl-Meyer scale and the Barthel index were used to assess ambula- tion and balance,and facility in the activities of daily living.All patients were assessed before and after the treat- ment.Results After four weeks of treatment,depression in the training group had improved significantly more than in the control group.Conclusion BWSTT intervention is very important for patients with PSD:it can reduce the degree of depression and improve the quality of life.

Objective To study the safety and efficacy of transhepatic arterial infusion embolization using microspheres combined with lipiodol for treatment of hepatocellular carcinoma(HCC).Methods Transhepatic arterial chemoembolization(TACE)was performed with 1-2 ml 300-500?m mierospheres and 10-20 ml lipiodol for treatment of HCC.Changes of liver function,AFP,responses of tumor and complications related to embolization were analyzed before and after TACE.Results Thirty six patients with HCC were enrolled into this study.After TACE,patients' liver function got worsen and tumor size decreased significantly(P＜0.05).Conclusion TACE with use of microspheres combined with lipiodol is an effective treatment for HCC,but should be taken carefully to avoid hepatic failure.

To investigate the structure disruption of BSA (1mg/ml, dissolved in PBS) induced by ultrasonication and the French press. The BSA solution was passed through the French press and received ultrasound irradiation, and then detected by HPLC(High-performance liquid chromatography),DLS(Dynamic Light Scattering),CD(Circular Dichroism)and nondenaturing SDS-PAGE. Detection results showed that BSA was polymerized after ultrasound irradiation and the polymerization can be reduced by adding mannitol (free radical scavenger). This means that the free radical play an important role in this process. However, the BSA passing through the French press for several times wasn’t polymerized, and the secondary structure was somewhat destroyed. These results suggested that ultrasound irradiation and French press destroy the molecular structure in different manners, so that the suitable cell lyses methods should be selected according to the characteristics of the protein.
