OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.

METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).

RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).

CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.

Using high pressure homogenization method combined with spray-drying, budesonide-loaded chitosan microparticles were prepared and the in vitro release profile was investigated. The microparticles were then blended with lactose using a vortex mixer, influence of mixing speed, mixing time on drug recovery rate and content homogeneity were investigated. Meanwhile, influence of lactose content on drug recovery rate, content homogeneity, powder flowability and in vitro deposition were studied. It turned out that budesonide was released from the microparicles in a sustained manner, with fine particle fraction as high as 46.0%, but the powder flowability was poor. After blending with 10 times of lactose, the drug recovery rate was 96.5%, with relative standard deviation of drug content 2.5%, and fine particle fraction of the formulation increased to 59.6% with good flowability. It's demonstrated that using a vortex mixer, budesonide sustained-release dry powder for inhalation with good recovery and content homogeneity could be prepared, the formulation had good flowability and was suitable for pulmonary inhaling.

Objective To explore the related factors for the prognosis in elderly cancer patients with cerebral metastases,to study the adaptability of brain metastasis in recursive partitioning analysis (RPA)and the prognosis Assessment (GPA) Scale,in order to provide the basis for the prognosis assessment and treatment in the elderly patients with brain metastasis.Methods A retrospective analysis was studied in 102 elderly cancer patients with brain metastasis (aged 60 years and over) with complete follow-up data in our hospital from January 2005 to January 2012.Survival analysis was performed by using the Kaplan-Meier method.Univariate analysis of ethnicity,age,Karnofsky score,gender,smoking,primary tumor origin,the number of intracranial metastatic tumor,intracranial and extracranial metastasis,the efficacy of treatment for primary tumor,the treatment of brain metastases were analyzed by Log-rank test.Results The median survival time was 6 months.The 6-month and 12-month survival rates were 54.90％ and 16.67％ respectively.Univariate analysis showed that Karnofsky score,smoking,the number of intracranial metastatic tumor,time to diagnosis and treatment,the efficacy of treatment for primary tumor and other underlying diseases were the relative factors for prognosis of elderly cancer patients with brain metastases (x2 =20.828,5.737,7.395,5.379,11.556,6.844,all P＜0.05).Cox multivariate regression analysis showed that the Karnofsky score,the number of intracranial metastatic tumor,the efficacy of treatment for primary tumor and other underlying diseases were the independent prognostic factors (all P＜0.05).The median survival periods in RPA class Ⅰ,Ⅱ,Ⅲ were 11,7,4 month respectively (x2 =27.358,P＜0.001).The median survival periods in GPA class Ⅰ,Ⅱ,Ⅲ-Ⅳ were 5,8,13 months respectively (x2 =29.570,P＜0.001).Conclusions Karnofsky score,the number of intracranial metastatic tumor,the efficacy of treatment for primary tumor and other underlying diseases are the independent factors for the prognosis in elderly cancer patients with cerebral metastases.RPA and GPA classification have a good adaptability in elderly patients with brain metastases.

Objective To investigate the processing characteristics of locative prepositions in patients with Chinese aphasia,and to provide the theoretical evidence for the rehabilitation of aphasia.Methods Twenty aphasic patients caused by left-hemisphere stroke and twenty matched normal controls were studied.Using the locative prepo- sition repeating task(single words,locative preposition phrases and words in sentences),the comprehension task, filling-gap task,the visual-spatial function task and the short-term memory task,we compared the performance be- tween these two groups.Results The aphasic patients had more difficulty in repeating locative prepositions in sen- tences,in comprehension task and filling-gap task,their short term memory was impaired.Both groups did well in re- peating single words and phrases.Conclusion The processing of locative prepositions was impaired in Chinese aphasics.The repetition of locative prepositions was more difficult than that of phrases and single words.The preposi- tions were often omitted.It might be due to the impairment of their short-term memory,or it might have something to do with role they played in the syntactic structure.The latter might also impact the comprehension and filling-gap score.We should make plans before rehabilitation therapy.

Background & Objective: Radiotherapy and temozolomide are the standard therapy for newly diagnosed glioblastoma multiforme (GBM). However, it is unclear whether adding another agent to the commonly used radiotherapy-temozolomide (RT + TMZ) benefits newly diagnosed GBM patients. The present network meta-analysis aimed to assess the efficacy of combining other agents with RT + TMZ for GBM treatment. Methods: A comprehensive literature search was conducted on PubMed, EMBASE.com, Web of Science, and the Cochrane Central Register of Controlled Trials from inception to September 23, 2014, to include all randomized controlled trials of RT + TMZ-based therapy in GBM patients. Pairwise and network meta-analyses were performed to compare the therapeutic regimens. Results: Seventeen studies involving 4,148 patients were identified. The results of pairwise meta-analysis indicated no significant differences among most comparison groups, except for bevacizumab + RT + TMZ versus RT + TMZ for progression-free survival (hazard ratio [HR] = 0.71, 95% confidence interval [CI]: 0.59–0.86; P = 0.000) and RT + TMZ versus RT alone for overall survival (HR = 0.71, 95% CI: 0.58–0.88; P = 0.001). The results of network meta-analysis also showed no significant differences in most comparisons; however, adverse events were more common among patients receiving additional therapeutic agents other than RT + TMZ. The ranking probability analysis indicated that bevacizumab + RT + TMZ and nimustine + cisplatin + RT + TMZ were associated with the best progression-free and overall survival, but they also caused the most adverse events in GBM patients. RT + bevacizumab + irinotecan had the highest probability of being the best regimen for minimizing adverse events. Conclusions: The addition of other targeted agents, particularly bevacizumab and nimustine, to RT + TMZ could be slightly effective for the treatment of newly diagnosed GBM patients; however, adverse events remained common.

AIM: To investigate the expression of connective tissue growth factor (CTGF) and α-SMA in human lens epithelium cell (HLEC) line B3 after transfection by liposome-coated siRNA targeting CTGF.METHODS: HLECs were transfected with small interfering RNA (siRNA) targeting CTGF,labeled with 5`-fluorescein isothiocyanate (5`-FITC) and coated with lipofectamine.The transfection ratio was evaluated via fluorescence intensity.Cell counting kit-8 (CCK-8) assay was performed to assess cytoviability of both non-transfected and transfected HLECs.Quantitative RT-PCR,cell immunochemistry and Western blot analysis were conducted to detect the expression changes of CTGF and α-SMA after transfection.RESULTS: A highly effective transfection ratio was observed in siRNA co-transfected with lipofectamine.The transfection ratio reached 95% at 24h.The proliferation of HLECs was inhibited by siRNA after 72h transfection.The expression of CTGF and α-SMA significantly decreased in HLECs after transfected by CTGF siRNA for 24h.This effect was not found in negative control siRNA.CONCLUSIONS: SiRNA targeting CTGF decreased CTGF and α-SMA expression in HLECs,which is a potential therapeutic strategy for posterior capsular opacification.

Objective To explore the effect of recovery sleep on the executive function after 36 h of total sleep deprivation by event related potential technology.Methods Thirteen healthy male college students participated in two trials. At the first trial normal sleep as control was investigated. At the second trial participants experienced 36 h of sleep deprivation and then accepted 8 h recovery sleep. In each trial six Go/Nogo tests were employed to test the executive control function and the ERP data were recorded. Results There was no statistical difference in behavior and ERP results at each time point as the subjects had normal sleep. After 36 h of sleep deprivation, the behavior results were statistically significant when compared to the baseline. The amplitude and latency of Nogo-N2, Nogo-P3 on Fz electrode, the amplitude and latency of Nogo-P3 on Cz electrode showed statistical significance when compared to the baseline. After 8 h recovery sleep, the average correct reaction time and the Go correct reaction rate had statistical significance compared to 36 h value. The amplitude of Nogo-N2 and Nogo-P3 had no statistical significance compared to the baseline.However,it was of statistical significance[(-6.80 3.95)vs(-3.37 2.63)μV,(10.63±6.62)vs(5.63±5.45)μV,(9.49±7.37)vs(6.08±6.56)μV] compared to 36 h value. The latency of the recovery value of Nogo-N2 and Nogo-P3 was statistically significant[(254.14±15.55)vs(243.08±13.97)ms(382.14±41.07)vs(349.17±30.36)ms,(369.86±26.48)vs(347.48±29.24)ms]compared to the baseline.Conclusion As the time of sleep deprivation is prolonged, the executive function is impaired and the executive function is not completely recovered after 8 h recovery sleep.
