Objective To observe the effect of ginkolide B derivative(XQ) on animal thrombosis.Methods SD male rats were randomized into the model group,troxerutin(48 mg?kg-1?d-1) group,ginkolide B(7.8 mg?kg-1?d-1) group,and low-,middle-and high-dose XQ(in the dose of 3.9,7.8 and 15.6 mg?kg-1?d-1 respectively) groups.The anti-thrombotic effect of XQ was observed on rats mixed thrombosis model induced by arterio-venous shunt method and electrical stimulation.Meanwhile,ICR male mice were randomized into the model group,troxerutin(96 mg?kg-1?d-1) group,ginkolide B(15.6 mg?kg-1?d-1) group,and low-,middle-and high-dose XQ(in the dose of 7.8,15.6 and 31.2 mg?kg-1?d-1 respectively) groups.The anti-thrombotic effect of XQ was also observed on mice acute pulmonary embolism model induced by adenosine diphosphate(ADP).Results XQ at the dose of 7.8 and 15.6 mg?kg-1?d-1 decreased the dry and wet weight of the thrombosis,and obviously prolonged the formation time of rats carotid artery thrombosis as compared to the model group(P

AIM: To investigate the inhibiting effect and mechanism of dimethylaminoethyl ginkgolide B mesylate on platelet aggregation and release function.METHODS: The effect of dimethylaminoethyl ginkgolide B mesylate on inhibiting PAF-induced platelet aggregation was measured by turbidimetry method through giving rabbits dimethylaminoethyl ginkgolide B mesylate at different final concentration via i.v.for 5 days.The release of Ca2 + from PAF-induced platelet in rabbits was assayed with fluorospectrophotometry and the contents of TXA2 and PGI2 were measured by radio-immunity method.RESULTS: Three groups of dimethylaminoethyl ginkgolide B mesylate (1.95,3.90,7.80 mg/kg) had significant effect on inhibiting PAF-induced platelet aggregation in rabbits (compared to normal,P

From the psychology point of view, the stroke patients have the cognitive process from sensation, perception to image and memory on spasticity, limbs synergic movement and normal movement when having rehabilitation. While treating the patients with Bobath or Brunnstrom therapy, the patients' motion perception and thinking memory should be promoted. Because the rehabilitation of body movement and psychological perception activity are influenced each other and inseparable.

Objective To study the impact of HIV and hepatitis C virus ( HCV ) infection on peripheral expression of antiviral protein A3G and plasma IFN-αlevels.Methods Untreated patients with chronic hepatitis C(HCV infection group, n=43), AIDS(HIV infection group, CD4 +T<200 cells/μL, n=45) and HIV/HCV co-infection (CD4 +T<200 cells/μL, n=45) were recruited in the study, and 23 healthy subjects were also enrolled as controls.A3G mRNA in peripheral blood mononuclear cells (PBMC) was measured by quantificational real-time PCR, and plasma IFN-αlevel was determined by enzyme linked immunosorbent assay (ELISA).Rank-sum test and Spearman rank correlation analysis were performed. Results A3G mRNA levels in HIV infected group, HIV/HCV co-infected group, HCV infected group and healthy control group were 4.89 (0.59), 4.85 (0.71), 3.89 (1.08) and 3.69 (0.81) lg copies/mL, respectively.A3G mRNA levels in HIV infected group and HIV/HCV co-infected group were much higher than those in healthy control group (Z=-6.306 and -6.280, P<0.01) and HCV infected group (Z=-7.358 and -7.275, P<0.01).Plasma IFN-αlevels in HIV infected group, HIV/HCV co-infected group, HCV infected group and healthy control group were 2.79 (1.25), 2.05 (1.29), 2.32 (1.84) and 2.16 (2.19) pg/mL, respectively.Plasma level of IFN-αin HIV infected group was higher than that in the HIV/HCV co-infected group (Z=-2.332, P<0.05), but no significant difference was observed among other groups (all P>0.05).There was no significant correlation between plasma IFN-αlevel and A3G mRNA expression (rs =0.04, P>0.05), and the levels of A3G mRNA and IFN-αshowed no correlation with HIV RNA and HCV RNA (all P>0.05).Conclusions A3G is highly expressed in PBMCs from HIV infected patients, and it may not be affected by the infection of HCV.A3G mRNA is not closely correlated with IFN-α, and it has not significant influence on HIV RNA and HCV RNA replication.

Objective To evaluate the efficacy and safty of antiviral treatment for chronic hepatitis B ( CHB ) patients in second trimester of pregnancy.Methods Seventy-nine CHB patients in second trimester of pregnancy were collected from Hangzhou First People’ s Hospital and Xixi Hospital of Hangzhou during January 2010 to December 2013.Patients were divided into antiviral treatment group ( n=47) and the control group (n=32) according to their own wishes.Patients in antiviral treatment group were given lamivudine or telbivudine treatment plus hepatoprotective medication, while those in control group were only given hepatoprotective medication.All pregnant women were observed for 12 weeks after childbirth and the neonates were followed-up for 6 months after birth.The liver function, HBV DNA loads, HBV serological markers were measured;adverse effects during pregnancy, blocking rates of mother-to-child transmission and the growth of neonates were documented.t test or Chi-square test was used for statistical analysis.Results Alanine aminotransferase ( ALT) normalization rate and HBV DNA negative rate in antiviral treatment group before childbirth were 88.6%(39/44) and 84.1%(37/44) , while those in the control group were 60.0%(18/30) and 0 (χ2 =8.27 and 50.46, P<0.05).After 12 weeks of childbirth, ALT normalization rate and HBV DNA negative rate in antiviral treatment group were both 100.0% (44/44), which were higher than those in control group (90.0%and 0) (χ2 =4.59 and 74.00, P<0.05).HBeAg seroconversion was observed in 1 (2.8%) and 4 (11.1%) patients in antiviral treatment group before and 12 weeks after childbirth, but it was not observed in the control group.The difference in HBeAg seroconversion rate bwteen two groups was not of statistical significance (P>0.05).No patient in antiviral treatment group terminated pregnancy due to abnormal liver function or adverse effect of drugs, while 2 out of 30 patients (6.7%) in the control group terminated the pregnancy, but the difference between two groups was not of statistical significance (χ2 =1.01, P >0.05).Mother-to-child transmission of HBV was successfully blocked in antiviral treatment group, while 3 cases (11.5%) in control group were failed (χ2 =5.19, P<0.05).No significant differences in gestational age, body mass, body length, Apgar score between two groups were observed (t=0.65, 0.84, 0.25 and 0.77, P>0.05).Conclusion Antiviral treatment can improve liver function, inhibit HBV replication and reduce the risk of mother-to-child transmission, and is safe for CHB patients in second trimester of pregnancy.

Objective To explore the diagnostic accuracy of urine liquid-based cytology(LBC)for diagnosis of urothelial carcinoma(UC).Methods A total of 603 cases in our department from January 2005 to July 2007 were subject to urine liquid-based cytology test(LBC)and followed by histological examination.Using the histological appearance as the gold standard,the accuracy of LBC test was evaluated.Results A total of 436 cases with histological diagnoses were selected.There were 274 cases of UC and 61 cases of other malignant tumors of urinary system.The sensitivity,specificity and accuracy of urine LBC test for malignant tumors were 61.5%,86.5% and 67.1%,respectively.The positive predictive value and negative predictive value were 94.1% and 39.2%,respectively.The sensitivity of urine LBC test for UC and non-urothelial malignant tumors were 68.6% and 29.5%,respectively.The sensitivity for UC Was significantly higher than that for non-urothelial malignant tumors.The diagnostic sensitivity of urine LBC test for UC G1,G1-2;G2,G2-3 and G3 was 53.3%,74.5% and 90.6%,respectively.The diagnostic sensitivity of urine LBC was increased with the increacment of histological grade of UC.Conclusions The sensitivity of urine LBC test for high grade UC is high and has a good clinical value.However,for the diagnosis of low grade UC,the sensitivity of LBC test is low and adjuvant test is needed to improve it.

[ ABSTRACT] AIM:To study the effect of idazoxan ( IDA) on the permeability of blood-brain barrier ( BBB) and the expression of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) in mouse ex-perimental autoimmune encephalomyelitis (EAE).METHODS: Female C57BL/6 mice (n=36) were randomly divided into control group, EAE group and IDA group, with 12 mice in each group.EAE was induced by myelin oligodendrocyte glycoprotein 35-55 ( MOG35-55 ) .IDA (2 mg/kg, ip, bid) was administered for 15 d after immunization.The neurological defects of the mice were observed daily and scored.The pathological changes were observed under microscope with HE stai-ning and LFB myelin staining.The BBB permeability was detected by Evans blue extravasation.The expression of MMP-9 and TIMP-1 in the brain of EAE mice was determined by Western blotting.RESULTS: Compared with EAE group, the score of neurological defects in IDA group was decreased, the inflammation was relieved, the BBB permeability was re-duced, and the expression MMP-9 and the ratio of MMP-9/TIMP-1 were decreased ( P<0.05 ) .CONCLUSION: The neuroprotective effect of IDA on mouse EAE might be related to the down-regulation of MMP-9 and the ratio of MMP-9/TIMP-1, thus reducing the degradation of BBB and the permeability of BBB, and ameliorating the pathologic process of EAE.

Objective:To demonstrate the state of the art and trends on the global status of chronic disease management of patients with systemic lupus erythematosus (SLE) in recent 30 years.Methods:Literature relating to chronic disease management of patients with lupus from 1989 to 2018 was retrieved from Web of Science TM, using Mesh terms "lupus" and "management". CiteSpace was used to analyze countries/institutions, authors/cited authors, cited references and keywords. The information visualization analysis of centrality and counts was used to reveal countries/institutions, active authors, cited references, hot topics and frontiers. Results:A total of 3 328 papers were included, and a year-by-year increase of the number of publications were noticed. Most productive authors were from Europe, who were also open to communication and collaboration. Dr. M Petri is a representative figure in the area of lupus and antiphospholipid syndrome. She was involved in the composition of lupus classification and treatment guidelines, and played important roles in the arena of lupus treatment. Most productive countries/organizations were/from the United States, the United Kingdom, Spain, Italy, since European countries and organizations paid much attention to colaboration. The basis was focused on the treatment and management of lupus nephritis, the classification of lupus, the classification criteria of APS, and the usage as wells efficacy evaluation of belimumab in lupus. According to the time trend, the most popular key words were treatment, classification, antiphospholipid syndrome, disease activity, pregnancy, which could be categorized to 14 clusters. We could predicted that comprehensive evaluation including the clinical efficacy and safety of biological agents, as well as studies on quality of life and psychological state of lupus patients would become the main stream in this area. The research focus shifted from the diagnosis and treatment of lupus to the quality of life of patients.Conclusion:CiteSpace is used to collect the information of the literatures about chronic disease management of lupus. The results have shown that chronic disease management is still a hot topic. CiteSpace could help us to identify authors and institutions that are collaborative, as well as the research subjects that may lead the directions and future development.

OBJECTIVETo investigate the value of the liquid-based cytology (LBC) of brushing specimens obtained via fiberoptic bronchoscopy for clinical diagnosis of lung cancer.

METHODSWe retrospectively analyzed the LBC cases in our hospital from January 2011 to May 2012, and evaluate its role in the diagnosis of lung cancer.

RESULTSThe clinical data of a total of 4 380 cases were reviewed and 3 763 of them had histopathological or clinical follow-up results (including 3 306 lung cancer cases and 457 benign lesion cases). The sensitivity, specificity, and accuracy of LBC diagnosis for lung cancer were 72.4% (2 392/3 306), 99.3% (454/457) and 75.6% (2 846/3 763), respectively. Of the 1 992 lung cancer cases diagnosed by brushing LBC, 528 cases (26.5%) were failed to take forceps biopsy and 113 cases (5.7%) showed negative forceps biopsy results. The accurate rate of subtyping of LBC for non-small cell carcinoma and small cell carcinoma was 99.0% (1 487/1 502) (P < 0.001). Take the resection histopathology as gold standard, the accurate rates of subtyping squamous cell carcinoma, adenocarcinoma and small cell carcinoma by LBC were 95.6% (351/367), 95.6% (351/367) and 100% (367/367), respectively, (P < 0.001). The accurate rates of subtyping of squamous cell carcinoma, adenocarcinoma and small cell carcinoma by forceps biopsy were 97.0% (293/302), 97.4% (294/302) and 99.7% (301/302), respectively, (Kappa = 0.895, P < 0.001). There was no significant difference in subtyping respectively between forceps biopsy and brushing LBC (P > 0.05).

CONCLUSIONSFiberoptic bronchoscopic brushing liquid-based cytology can significantly improve the detection rate of lung cancer, and have a high specificity and accurate rate of subtyping. It is an effective tool for the diagnosis and subtyping of lung cancer.
