48 hours.The expressions of leukocyte common antigen(LCA) and intercellular adhesion molecule-1(ICAM-1) in the brain tissues collected during the surgery were detected by immunohistochemistry staining method.Results LCA and ICAM-1 immunopositive cells and microvessels were verified in all 29 cases of ICH groups,and the expressions were more than control group(all P48 hours group were higher than that in 6~24 h group(both P48 hours group.Conclusions Acute inflammatory reaction occurs in acute period of ICH.Expression of ICAM-1 reinforces gradually during early 48 hours since the onset of ICH.

Objective To observe the pathological changes of cerebral arterioles around hematom in patients with acute period of intracerebral hemorrhage. Methods Brain tissue fragments were collected from the drainage effluents of 43 patients who received mini-invasive puncture drainage treatment of acute intracereal hemorrhage. Pathological changes of arterioles were analyzed under light microscope by routine HE and Congo red staining, respectively. Results The primary pathological changes of cerebral arteriole around hematom was arteriosclerosis and hyaline degeneration, which accounted for 28 cases (65.12%). Other pathological etiological factors included atherosclerosis in 3 cases (6.98%) and thrombosis in 5 cases (11.63%). Light microscopy also showed neutrophilic granulocytes sticking on the endothelial cells and exuding around vessels in 10 cases (23.26%) from 6h to 4d, and mini-focal hemorrhage in 8 cases (18.6%) from 24 to 48h.Conclusions Arteriosclerosis is the principal pathological etiology for spontaneous intracerebral hemorrhage. Neutrophilic granulocytes infiltrating was one of the most important pathological changes in acute stage of intracerebral hemorrhage.

Effect of 8 fungal fermented filtrates on mycelial growth, encystment and germination of zoospores, appressorium formation, and penetration hyphae formation of Phytophthora infestans was investigated. Of which, the fermented filtrates from Rhizoctonia solani and Colletotrichum gloeosporioides showed the strongest inhibition against P. infestans. The results indicated that they are potential for controlling the diseases caused by P. infestans.

Electric and electronic products are required to pass through the certification on electrical safety performance before entering into the market in order to reduce electrical shock and electrical fire so as to protect the safety of people and property. The leakage current is the most important factor in testing the electrical safety performance and the test theory is based on the perception current effect and threshold. The traditional method testing the current threshold for perception only depends on the sensing of the human body and is affected by psychological factors. Some authors filter the effect of subjective sensation by using physiological and psychological statistical algorithm in recent years and the reliability and consistency of the experiment data are improved. We established an experiment system of testing the human hody's current threshold for perception based on EEG feature analysis, and obtained 967 groups of data. We used wavelet packet analysis to detect a wave from EEG, and used FFT to do spectral analysis on alpha wave before and after the current flew through the human body. The study has shown that about 97.72% alpha wave energy changes significantly when electrical stimulation occurs. It is well proved that when the EEG feature identification is applied to test the human body current threshold for perception, and meanwhile alpha wave energy change and human body sensing are used together to confirm if the current flowing through the human body reaches the perception threshold, the measurement of the human body current threshold for perception could be carried out objectively and accurately.

As one of the major geriatric syndromes,frailty exerts adverse effects on life expectancy and quality of life of the elderly.Because of its importance,a number of methods and tools have been introduced for the assessment of frailty.Malnutrition,as an independent risk factor,interacts with frailty and is involved in its progression.This article reviews recent studies on frailty and malnutrition.

Objective To evaluate the efficacy and safety,particularly eye safety of hydroxychloro-quine(HCQ)treatment in primary Sj(o)gren's syndrome(pSS)patients.Methods Forty pSS patients were en-rolled and treated with HCQ 400 mg/day for 12 months.This is a prospective open-label study.Clinical mani-festations,clinical efficacy,biochemical and immunoserological parameters as well as ophthalmological exami-nations were investigated every three months to assess the safety and tolerability.Results There were signifi-cant decrease in the erythrocyte sedimentation rate(ESR),immunoglobulin G(IgG),immunoglobulin M (IgM)and rheumatoid factor(RF)level after 6 months treatment with HCQ(P<0.01 or P<0.05).No changewas detected in serum antinuclear antibody(ANA),anti-SSA/SSB antibodies after treated for 12 months.Somepatients had partial improvement in symptoms such as dry mouth,dry eyes and arthralgia.During the treat-ment,no significant effect on serum alanine aminotransferase (ALT),blood urea (BUN),serum creatinine (Cr),whole blood count(WBC)or hemoglobin(Hb)could be discovered.Central semus retinopathv(CSR)was found in one patient after 6 months treatment with HCQ.However,its association with HCQ could not be confirmed since it was not compatible with the usual HCQ retinopathy.Conclusion HCQ can improve svmp-toms of some pSS patients and can significantly decrease ESR,IgG,IgM and RF level.The safety profile of HCQ is generally good.However,ophthalmological examination before and after a 6-month interval may be necessary in long term HCQ treatment.

Objective To explore the feasibility of using the quantitative reference extract of ginkgo leaf total lactones instead of single component reference for the quantitative assay of Ginkgo Folium.Methods HPLC-ELSD method was performed by using a Diamonsil C18 column (250 mm×4.6 mm,5 μm) with methanol-water as the mobile phase at the gradient elution mode.Flow rate was 1.0 mL·min-1.The parameters of ELSD detector were as follows,the drifit tube temperature was 105 ℃,and the flow rate of nitrogen(N2) was 3 L·min-1.Results The linear ranges of ginkgolide A,ginkgolide B,ginkgolide C,and bilobalide were 0.735-5.879 μg (r=0.999 6),0.404-6.060 μg (r=0.999 6),0.296-4.439 μg (r=0.999 6),and 1.001-6.006 μg (r=0.999 7),respectively.The recoveries and RSD of the four components were 95.6% (4.0%),97.3% (4.5%),99.3% (5.0%),and 100.4% (2.1%),respectively.Conclusion The quantitative reference extract of ginkgo leaf total lactones can be used as the substitute for the determination of terpene lactones.
