OBJECTIVETo investigate the clinical value of Paroxetine combined with mid-frequency electrical pulse acupoint stimulation (EPAS) in the treatment of premature ejaculation (PE).

METHODSTotally 69 PE patients were equally assigned to receive oral Paroxetine 20 mg/d, mid-frequency EPAS, or oral Paroxetine 10 mg/d combined with mid-frequency EPAS (P + EPAS) , all for 8 weeks. We obtained the intravaginal ejaculation latency time (IELT) and Chinese Index of Premature Ejaculation (CIPE-5) scores of the patients before and after treatment, and compared adverse reactions among the three groups of patients.

RESULTSOne patient of the Paroxetine group gave up treatment because of abdominal pain and nausea. Compared with the baseline, the patients in the Paroxetine, EPAS, and P + EPAS groups all showed markedly increased IELT ([0.92 ± 0.11] vs [4.07 ± 0.11] min, P < 0.01; [0.92 ± 0.12] VS [2.78 ± 0.17] min P < 0.05; [0.91 ± 0.09] vs [5.31 ± 0.13], P < 0.01) and decreased CIPE-5 scores (12.5 ± 3.0 vs 22.0 ± 2.1, P < 0.01; 12.8 ± 2.9 vs 19.5 ± 1.9, P > 0.05; 13.1 ± 2.8 vs 25.2 ± 2.1, P 0.01), with statistically significant differences between the P + EPAS group and the other two (P < 0.05). The total effectiveness rate was 95.7% in the P + EPAS group, remarkably higher than in the Paroxetine (72.7%, P < 0.05) and the EPAS group (47.8, P < 0.01).

CONCLUSIONOral Paroxetine combined with mid-frequency EPAS has a higher safety and efficacy than either Paroxetine or EPAS alone in the treatment of PE.

Objective:The present study was designed to test the hypothesis that inflammation is involved in the end-organ damage(EOD) induced by sinoaortic denervation(SAD) in rats.Method:SAD was performed in male Sprague-Dawley rats at the age of 10 weeks.Under anaesthesia,aortic nerves were cut and the sinus region of the carotid artery was stripped and painted with 10% phenol.Pathological evaluation of EOD and the determination of plasma or tissue levels of the factors related to inflammation,including thromboxane B2(TXB2) interleukin-1(IL-1),tumour necrosis factor α(TNF-α) and reactive oxygen species(ROS) were performed at 16 weeks after SAD.Pathological evaluation of EOD included heart weigh ratio,myocardial and blood vessel hydroxyproline and collagen volume fraction,glomerular injury score and number of infiltrating inflammatory cells.Indomethacin(20 mg/kg per day,orally) or vitamin E(100 mg/kg per day,orally) was administered for 12 weeks,beginning from4 weeks after SAD,to observe their effects on SAD-induced EOD.Results:There were significant fibrosis and inflammatory infiltration in the myocardium and blood vessels,represented by higher hydroxyproline and collagen volume fraction,and a large amount of inflammatory cells in the tissues of SAD rats.Heart weight and kidney glomerular injury score were significantly higher in ed significantly after SAD.Indomethacin and vitamin E significantly decreased the contents of some factors related to inflammation in SAD rats.Both drugs also alleviated myocardial and vessel fibrosis,inflammatory infiltration and kidney damage.Conclusion:Inflammation is involved in the organ damage induced by SAD in rats.

Objective To investigate the feasibility of ~1H-MR spectroscopy(~1H-MRS)imaging to quantitatively detect fatty liver.Methods Twenty patients with fatty liver and 11 healthy volunteers underwent plain CT scan,conventional MR imaging and ~1H-MRS analysis.The blood lipid and liver function were tested on the same day as the MR examination.~1H-MRS sequence measured the peaks of H_2O and lipid,and the areas under the peaks.The relative contents of the lipid compound were calculated,and compared with the results of CT scan and liver function tests.Results The CT values of the normal group and the fatty liver group were(59?9)HU and(24?11)HU respectively.On ~1H-MRS a protruding high H_2O peak and a flat low lipid peak were observed in the normal group,while the protruding high H_2O peak and a high lipid peak appeared in the fatty liver group.The values of lipid peak in the normal group and the fatty liver group were(0.05?0.01)?10~5,(0.70?0.24)?10~5 respectively(t=4.32,P0.05),the areas under the lipid peak were(1.36?0.73)?10~9、(2.35?1.15)?10~9 respectively(t=5.21,P0.05).Conclusion ~1 H-MRS imaging is feasible to quantitatively detect liver fat and is a non-invasive method for detecting early fatty liver.

The rate of corneal graft rejection is still high for high-risk keratoplasty although immune suppression drug is routinely used.The role of traditional Chinese medicine in corneal transplantation is concerned gradually.Heijingpaichitang on the prevention and treatment of rats with high-risk corneal allograft rejection needs further study.Objective This study was to investigate the inhibitory effect of heijingpaichitang on high-risk corneal transplantation immune rejection in rats.Methods Sixteen female SD rats were used as the donors and 32female Wistar rats were served as recipients.The high-risk corneal trasplantation models were established by corneal suture in 32 Wistar rats,and then homogeneity variant SD-Wistar corneal transplantation was performed.The recipients were randomized into model control group,cyclosporinc A (CsA)group,heijingpaichitang group and CsA +heijingpaichitang group.CsA,heijingpaichitang and CsA + heijingpaichitang was orally administered 4 days after operation once per day for 15 days,and normal saline solution was used at the same way in the model control group.Ocular anterior segment reaction was examined under the slit lamp and corneal opacification,edema and neovasculation were scored based on Larkin' s criteria.Rejection index of the corneal graft was recorded and the graft survival time was calculated.The pathological examination of the corneal graft was carried out in all rats,and the inflammatory cells in the corneas and CD4+ cells in the periphery blood were assayed using flow cytometry.The use of the animals complied with ARVO Statement.Results Corneal graft rejection occurred in 10 days after operation in the model control group,12-13 days in the CsA group and heijingpaichitang group and 22 days in the CsA +heijingpaichitang group.Compared with model control group,the scores of the corneal opacification,corneal edema and neovascularization were significantly lower in the CsA group,heijingpaichitang group and CsA+heijingpaichitang group (P＜0.05),and all the scores were declined in the CsA+ heijingpaichitang group compared with CsA group and heijingpaichitang group(P＜0.01),but no significant differences were seen in the scores between the CsA group and heijingpaichitang group(P＞0.05).The mean survival time of grafts was (10.38 ±1.69)days in the model control group,(22.50 ± 3.07) days in the CsA + heijingpaichitang group,with the significant difference (t =-9.790,P =0.000).The pathological examination of graft showed that the lymphocytes and new blood vessels were less in the CsA+heijingpaichitang group compared with CsA group and heijingpaichitang group 15 days after operation.Flow cytometry verified that the number of lymphocytes in graft,CD4+cells and CD4+/CD8+ in periphery blood were significantly lower in the heijingpaichitang group,CsA group and CsA+heijingpaichitang group compared with model control group (P＜0.05).Conclusions Heijingpaichitang can inhibit immune rejection to certain extent in high-risk corneal transplantation rat and has a similar effect to 0.1％ CsA.Heijingpaichitang and 0.1％ CsA have a synergistic effect.

To explore the potential of the anti-sense nucleic acid of CyclinD1 in lung cancer therapy, the expression vector containing the anti-sense nucleic acid of CyclinD1 was constructed and named pcDNA3.1-CyclinD1. The A549 cells were transfected with pcDNA3.1-CyclinD1 vectors. After being screened by G418, the stable expression positive clones were obtained. MTT method and flow cytometry technique were used to detect cell proliferation and apoptosis, respectively. The results showed the transfected cells exhibited significantly increased apoptosis and inhibited cell growth, compared with negative control and empty vector groups. To investigate the mechanism for anti-sense nucleic acid of CyclinD1 inducing A549 cells apoptosis, the expression levels of retinoblastoma protein (pRb), adenovirus E2 factor-1 (E2F-1), vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2 and MMP-9 were detected by Western blot, and the results showed the expressions of these proteins were all decreased significantly in anti-sense nucleic acid of CyclinD transfected group, compared with those in negative control and empty vector groups. In a word, anti-sense nucleic acid of CyclinD1 induces the apoptosis of lung adenocarcinoma cancer cells, and the depressions of pRb, E2F-1, VEGF, MMP-2 and MMP-9 expressions may be the possible mechanism.

To examine the feasibility of low-charge electrotherapy (LCE) in treating geriatric major depressive disorder (MDD) patients. Bi-temporal LCEs (approximately 25 mC) were performed with an electroconvulsive therapy (ECT) instrument three times per week. We used the Hamilton Depression Scale 17 (HAMD-17) and the Hamilton Anxiety Scale (HAMA) to assess the effects of LCE and the Mini-Mental State Examination (MMSE) to evaluate the cognitive function change before and after LCE. Six visits occurred at the baseline, after LCE sessions 3, 6, and 9, after the last session, and at the end of the one-month follow-up period. Four patients were enrolled in the study. Two patients completed all LCE sessions. Two patients withdrew during the trial, one due to the adverse event of uroschesis potentially caused by atropine and the other due to her own will. All four patients completed the follow-up sessions. The HAMD-17 and HAMA scores were reduced significantly at the last LCE session and the end of the follow-up period compared with the scores at the baseline. As measured by the MMSE, cognitive impairment showed no significant changes at the last LCE session and the end of the follow-up period compared with that at the baseline. In this case series, LCE showed potential as an alternative current-based treatment for treating geriatric MDD patients. Further research is needed to assess the efficiency and safety of LCE.

Objective To explore the relationship between the tumor necrosis factor-α(TNF-α) T1031C and C863A gene polymorphisms and senile ischemic stroke (IS) in elderly patients.Methods One hundred and fifty patients with IS and 110 age and gender-matched controls were recruited in this study. The T1031C and C863A gene polymorphisms were detected by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay in these subjects. Data were coded and analyzed in SPSS Windows (version 11.5): the differences of genotype and allele frequencies were analyzed and compared byx2 test; multiple logistic regression analysis was employed to analyze the effect of various risk factors on IS. Results The frequencies of CA+AA genotypes (0.387) and A allele (0.203) at the position of-863 in the IS group were significantly higher than those in the control group ([0.255 and 0.127]; [χ2=5.004, P=0.025] and [χ2=5.176, P=0.023]). Further analysis indicated that the frequencies of genotypes and alleles were statistically different between male IS subgroup (0.430 and 0.227) and controls ([0.212 and 0.106]; [x=7.968, P=0.005] and [χ2=7.557, P=0.006]). No differences of TC+CC genotypes and C alleles at the position of-1031 were observed between IS group and controls ([χ2=1.463, P=).226] and [χ2=2.849, P=0.091]). Multiple logistic regression analysis revealed that hypertension, diabetes mellitus, hyperlipidemia and the A allele of C863A gene polymorphism were independent risk factors for IS in elderly patients (P=0.022, OR=1.846, 95%CI: 1.075～3.169).Conclusion The TNF-α C863A gene polymorphism may be an independent risk factor for senile IS.The T1031C gene is unlikely to contribute to the IS.
