Objective To explore the rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Design Restrospective case series.Participants 92 cases with idiopathic intracranial hypertension.Meth- otis All patients diagnosed with papilledema from January 1,2000 through May 1,2007 at our ophthalmology center.Consecutive pa- tients with a diagnosis of papilledema were identified.Patients with space-occupying lesions,hydrocepbalus,or meningitis were excluded. The remaining patients were evaluated with lumbar puncture,magnetic resonance imaging(MRI)and magnetic resonance venography (MRV).Main Outcome Measures The rate of incidence of cerebral venous sinus thrombosis(CVST)in patients with idiopathic in- tracranial hypertension(IIH).Results Excluding patients with mass lesions,meningitis,or hydrocephalus,the occurrence of CVST was 7 (7.6%)of 92 patients with presumed IIH.One additional patients had a diagnosis of suspected CVST.Cerebral venous sinus thrombosis was diagnosed in 1 of the 7 patients with MRI alone,whereas it was evident in all 7 patients with MRV.Conclusions Cerebral venous si- nus thrombosis accounts for 7.6% of patients with presumed IIH in our ophthalmology services.Magnetic resonance venography in com- bination with MRI is recommended to identify this subgroup of patients.(Ophthalmol CHN,2007,16:410-413)

As an important synthetic antibacterial drug, sulfonamides play an important role in the anti-infection field. Based on the research and development status of sulfonamides, this paper broke the classical structure of sulfanilamide, and designed and synthesized a series of acetyl-contained sulfanilamide tertiary amine thiol azole compounds and sulfanilamide tertiary amine amino azole compounds. The structures were confirmed by ¹H NMR, ¹³C NMR and HRMS. The antimicrobial activity of synthesized compounds in vitro was tested. The antimicrobial activity of amino triazole compound 7a gave stronger activity against Pseudomonas aeruginosa than that of positive control drug norfloxacin, and its inhibitory activity against Staphylococcus aureus was close to that of norfloxacin. The interaction between compound 7a and calf thymus DNA was studied, and the docking experiment between this compound and DNA was also researched.

OBJECTIVETo investigate the effects of mifepristone on cell proliferation of human androgen-independent prostate carcinoma cell lines DU-145, PC-3 in vitro and the possible mechanisms involved.

METHODSThe A values of the prostate cancer cells DU-145 and PC-3 in each group with various concentrations (1, 10, 50, 100 micromol/L) of mifepristone at various time intervals (24-120 h) were detected with the colorimetric 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl tetrazolium bromide assay. The apoptosis rates of the DU-145 and PC-3 cells treated with 10 micromol/L of mifepristone for 24 h and 48 h were assessed by flow cytometry analysis technique. Immunohistochemical technique was used to determine the expression of bax, bcl-2 and vascular endothelial growth factor (VEGF) proteins after treatment with 10 micromol/L of mifepristone.

RESULTSThe A values of the cancer cells treated with 1 micromol/L of mifepristone were similar to that of controls, while those of the cells treated with 10 micromol/L, 50 micromol/L and 100 micromol/L of mifepristone were significantly different from that of controls (P < 0.01). Mifepristone markedly inhibited cell proliferation of prostate cancer cells DU-145 and PC-3 on a dose- and time-depending manner. The apoptosis rates of 10 micromol/L mifepristone for DU-145 cell line at 24 h, 48 h were respectively 15.3%, 30.4% with flow cytometry method and then PC-3 cell line were respectively 22.2%, 32.0%. Immunohistochemical technique showed the expression of bcl-2 and VEGF in the DU-145 and PC-3 cells treated with 10 micromol/L of mifepristone were significantly decreased, and the expression of bax was increased.

CONCLUSIONSMifepristone can induce apoptosis of androgen-independent prostate cancer cell lines DU-145 and PC-3 in vitro. The apoptosis effect is time-and-dose dependent. Mifepristone could initiate a cell death command via apoptotic pathways decreasing the expression of VEGF protein, downregulating the expression of bcl-2 protein and increasing the expression of bax protein.

Objective To observe the effects of iguratimod ( IT) combined with methotrexate ( MTX) in patients with refractory rheumatoid arthritis ( rRA) . Methods Sixty patients with rRA were randomly divided into 2 groups ( n=30 each group) . The cases in treatment group received 50 mg.d-1 of iguratimod and 10 mg of MTX for 16 weeks. The cases in control group were treated by 10-15 mg of MTX. DAS28 was analyzed. Levels of VEGF and endostatin ( ES) were quantified. Results In the treatment group,after 16-week treatment,DAS28,levels of VEGF and ES were (3.0±1.2),(818.9±178.8) pg.mL-1, (337.8±132.6) ng.mL-1,and those in the control group were (5.7±1.9),(1000.2±245.9) pg.mL-1,(253.8±77.8) ng.mL-1,respectively. In the treatment group,DAS28 and VEGF after the treatment were significantly decreased as compared with those before the treatment ( P<0.01) . The decrement was more significant in the treatment group than in the control group ( P<0.01) . At the 16th week of treatment,ES was significantly increased as compared with that before the treatment ( P<0.01) , and there was a significant difference between the treatment group and the control group (P<0.01). Conclusion Iguratimod combined with MTX have a prominent effect on rRA with high safety. The efficacy of IT on RA might be related with decreasing VEGF release,increasing ES production and alleviating synovium angiogenesis.

OBJECTIVETo explore the neutralization capacities of different types of human serum to measles virus epidemic strains and vaccine strain.

METHODSNeutralization antibody (NT) to Shanghai 191 and measles virus isolates in 2005 were tested using acute and convalescent serum samples from diagnosed measles patients, children serum samples collected before and after vaccination and serum samples of migrant residents, from 3 different regions. Additionally, animal immune serum referring to vaccine strain and 3 epidemic strains were prepared and used to undergo crossing neutralization test with corresponding strains mentioned-above. Antigenic ratios were calculated.

RESULTSGMT value of NT of after-immune serum to vaccine strains was 50.82,1.86 times higher than that to MVi/ZJ/05/7 (GMT was 27.35), whereas GMT value of convalescent serum to MVi/ZJ/05/7 (GMT was 386.95) was obviously higher than that to vaccine strain (GMT was 1:151.83),and GMT value of migrant residents' serum in 3 regions to MVi/ZJ/05/7 were 2.22-4.17 times lower than that to vaccine strain. Meanwhile,the antigenic ratios between MVi/ZJ/ 99/1, MVi/ZJ/04/1, MVi/ZJ/05/7 and vaccine strain were found to be 4.28,5.24 and 5.66 respectively. Additionally,low NT titers to vaccine strain were found in patients' acute sera and GMT value was over 1:4.

CONCLUSIONThere were obvious differences on neutralization antibody of different types of serum to measles vaccine strain and epidemic strains which indicating the antigenic diversity of epidemic strains had influenced the protective effectiveness of vaccine antibody to epidemic strains. It was of significance to carry on research projects on the antigenic diversity and effectiveness of measles vaccine.

OBJECTIVETo evaluate the sex therapy for erectile dysfunction (ED).

METHODSWe recommended the sex therapy to ED patients and their partners (11 couples in all) in the outpatient department. Of the total number of volunteers, 2 males were accompanied by ejaculation disorder, another 2 with hyposexuality, and 1 female had vaginismus. The effect of the therapy was assessed and the problems with it analyzed by interviews with the subjects and the results of International Index of Erectile Function (IIEF) before and after the treatment.

RESULTSOf the 11 pairs of volunteers, 5 quitted halfway and 1 discontinued at the therapists' decision. The 5 couples who accomplished the whole therapy felt more satisfied with their sexual life and general relationship, with improved scores on all the items of IIEF, particularly on erectile function (EF), with the only exception of sexual desire (SD).

CONCLUSIONThe sex therapy is effective not only for ED but also for other accompanying sexual dysfunctions, the sexual dysfunctions of the patients' partners and the improvement of the general relationship of the couples.

OBJECTIVETo discuss the factors that affect the clinical application of sex therapy for erectile dysfunction (ED).

METHODSUrological researchers recommended free sex therapy to ED patients and their partners in the outpatient department and studied the factors affecting the patients of Medicaid their partnersology, acceptance of sex therapy by interview and observation.

RESULTSMany patients refused sex therapy. Only 11 pairs of volunteers underwent it, of whom 5 pairs gave up halfway, 1 pair were stopped by the therapist due to the breakup of their marriage, and merely 5 pairs accomplished the whole course. Among the 5 pairs of quitters, 2 pairs thought of their problem as organic and turned to drug therapy, 1 pair withdrew because the patient's girlfriend broke up with him, 1 pair gave up because they lived in another city too far away from the clinic, and the other pair discontinued because they could not spare the time from their work.

CONCLUSIONSMany factors affect the clinical application of sex therapy for ED in China. Apart from the shortage of qualified professional sex therapists, some factors from the patients and their partners are at work, such as stress of work, lack of time, home location, education background, relationship between the patient and his partner, attitude to sex therapy, and so on.

OBJECTIVETo detect CCL20 and CXCR4 expressions in epidermis infected with condyloma acuminatum (CA) and normal epidermis and investigate the effect of their expressions on Langerhans cells in CA epidermis.

METHODSGene expression of CCL20 and CXCR4 in 3 epidermal CA lesions and in 3 normal epidermis specimens were detected using Affymetrix oligonucleotide microarrays HG-U 133A 2.0, and the protein levels of CCL20 and CXCR4 in these specimens were measured by Western blotting.

RESULTSMicroarray analysis revealed markedly down-regulated mRNA expressions of CCL20 and CXCR4 in the 3 epidermal CA lesions as compared with those in the normal specimens. Western blot analysis showed that the protein expressions of CCL20 and CXCR4 in the CA lesions were significantly lower than those in normal epidermis.

CONCLUSIONThe protein and mRNA expressions of CCL20 and CXCR4 are markedly down-regulated in epidermal CA lesions, which may contribute to decreased number and backflow disturbance of Langerhans cells in these lesions.
