Abstract
OBJECTIVE The pathogenesis of diarrhea-predominant irritable bowel syndrome (IBS-D) is related to damage to the intestinal mucosal barrier function. Based on the Mast cell (MC)/Tryptase/Protease-activated receptor-2 (PAR-2)/Myosin light chain kinase (MLCK) pathway, this study explored the effect of electroacupuncture (EA) on IBS-D rats and its possible mechanism of protecting the intestinal mucosal barrier. METHODS The IBS-D rat model was established by mother-offspring separation, acetic acid enema, and chronic restraint stress. The efficacy of EA on IBS-D rats was evaluated by observing the rate of loose stool (LSP) and the minimum volume threshold of abdominal withdrawal reflex (AWR) in rats. Mast cells and the ultrastructure of intestinal mucosa were observed by H&E staining, toluidine blue staining, and transmission electron microscopy. The expression levels of Tryptase, PAR-2, MLCK, zonula occludens-1 (ZO-1), and Occludin in rats were detected by ELISA, qRT-PCR, and western blot. RESULTS After 7 days of intervention, compared to the IBS-D group, the loose stool rates of rats in IBS-D + EA group and IBS-D + ketotifen group were decreased (P < 0.01), the minimum volume thresholds of AWR were improved (P < 0.01), the inflammation of colon tissue decreased, the number of MCs were decreased (P < 0.01), the expression of Tryptase, PAR-2, and MLCK were lowered (P < 0.01, P < 0.05), and the expression of ZO-1 and Occludin were enhanced (P < 0.01, P < 0.05). Compared to the EA group, there was no significant difference in each index between the ketotifen groups (P > 0.05). CONCLUSION EA has a good therapeutic effect on IBS-D rats. Regulating the MCs/Tryptase/PAR-2/MLCK pathway may be a mechanism to protect the intestinal mucosal barrier.

Abstract
OBJECTIVES To observe the effect of moxibustion intervention on the hypothalamus-spinal cord-colon axis of rats with irritable bowel syndrome with diarrhea (IBS-D) and explore the mechanism of moxibustion in improving visceral hypersensitivity in rats with IBS-D. METHODS A total of 36 SD rats were randomly divided into normal, model, and moxibustion groups, with 12 rats in each group. The IBS-D model was established by maternal separation + acetic acid stimulation + chronic restraint. Rats of the moxibustion group received bilateral moxibustion on "Tianshu" (ST25) and "Shangjuxu" (ST37) for 15 min, once a day for 7 consecutive days. The body weight, loose stool rate, and minimum threshold volume of abdominal withdrawal reflex (AWR) were measured before and after moxibustion intervention, respectively. The histopathological changes in the colon tissue were observed after HE staining. The number of colonic mucosal mast cells (MCs) was measured by toluidine blue staining. The activation of MCs was determined by tryptase positive expression level and examined by immunohistochemical staining. The content, protein and mRNA expression levels and positive expression levels of corticotropin releasing factor (CRF), substance P (SP), and calcitonin gene-related peptide (CGRP) in the hypothalamus, spinal cord and colon tissues were measured by ELISA, Western blot, real-time fluorescent quantitative PCR and immunofluorescence staining, respectively. RESULTS Compared with the normal group, the loose stool rate was increased (P<0.01);the body weight and minimum threshold volume of AWR were decreased (P<0.01);the inflammatory infiltration of colon tissues was obvious;the number of MCs and positive expression level of tryptase in the colon tissue were increased (P<0.01);the contents, positive expression le-vels, protein and mRNA expression levels of CRF, SP and CGRP in the hypothalamus, spinal cord and colon tissues were increased (P<0.01, P<0.05) in the model group. After the intervention, compared with the model group, all these indicators showed opposite trends (P<0.01, P<0.05) in the moxibustion group. CONCLUSIONS Moxibustion can improve visceral hypersensitivity in rats with IBS-D, and its mechanism may be related to regulating the hypothalamic-spinal-colon axis to reduce the release of CRF, SP and CGRP, and thus to inhibite MC in colon tissue.

Abstract
OBJECTIVE To observe the effect of moxibustion on the expression of miR-345-3p, miR-216a-5p and nuclear factor-κB p65(NF-κB p65) in colonic tissue of rats with diarrhea-predominant irritable bowel syndrome (IBS-D), so as to explore its anti-inflammatory mechanism in relieving IBS-D. METHODS SD rats were randomly divided into normal control (n=12), model (n=12), moxibustion (n=12) and ammonium pyrrolidine dithiocarbamate (PDTC,n=12) groups. The IBS-D model was established by neonatal mother-child separation combined with acetic acid enema stimulation and chronic binding methods. The rats in the moxibustion group received moxibustion stimulation of "Tianshu"(ST25) and "Shangjuxu"(ST37) for 20 min, once a day, for 7 days, and those of the PDTC group received intraperitoneal injection of PDTC (50 mg·kg-1·d-1) once daily for 7 days. After the intervention, the body weight, loose stool rate and the minimum volume threshold of abdominal withdrawal reflex (AWR) were observed, and histopathological changes of colonic mucosa were observed by HE staining. The contents of interleukin-1β (IL-1β), interleukin-4 (IL-4), interleukin-6 (IL-6) and tumor necrosis factor α (TNF- α) in serum were measured by ELISA. The expression of miR-345-3p, miR-216a-5p and NF-κB p65 mRNA in the colon tissue were detected by quantitative real-time PCR, and the immunoactivities of IL-1β, IL-6, TNF-α and NF-κB p65 in the colon tissue were determined by immunofluorescence histochemistry. RESULTS Compared with the normal control group, the loose stool rate, contents of IL-1β, IL-6 and TNF-α, experssion of NF-κB p65 mRNA and the immunoactivities of IL-1β, IL-6, TNF-α and NF-κB p65 were significantly increased (P<0.01), whereas the body weight, minimum volume threshold of AWR, content of IL-4, and the relative expression of miR-345-3p and miR-216a-5p were remarkably decreased in the model group (P<0.01). In comparison with the model group, the loose stool rate, contents of IL-1β, IL-6, TNF-α, expression of NF-κB p65 mRNA and the immunoactivities of IL-1β, IL-6, TNF-α and NF-κB p65 were considerably down-regulated (P<0.01), while the content of IL-4 and the relative expressions of miR-345-3p and miR-216a-5p were obviously up-regulated in both moxibustion and PDTC groups (P<0.01, P<0.05). The content of IL-6 in serum was significantly lower in the PDTC group than in the moxibustion group (P<0.01). CONCLUSION Moxibustion can reduce the level of intestinal inflammation and visceral hypersensitivity in IBS-D rats, which may be related to its functions in increasing the expression levels of miR-345-3p and miR-216a-5p and in inhibiting the expression of NF-κB p65, thus reducing the levels of inflammatory factors.

Abstract
OBJECTIVE To observe the effects of moxibustion on the stem cell factor (SCF)/tyrosine kinase receptor (c-kit) signaling pathway and immune function in rats with diarrhea irritable bowel syndrome (IBS-D), and to explore the mechanism of moxibustion for IBS-D. METHODS Among 52 young rats born from 6 healthy pregnant SPF rats, 12 rats were randomly selected into the normal group, and the remaining 40 rats were treated with the three-factor combination method of maternal separation, acetic acid enema and chronic restraint stress to establish the IBS-D rat model. Thirty-six rats with successful IBS-D model were randomly divided into a model group, a moxibustion group, and a medication group, 12 rats in each group. The rats in the moxibustion group were treated with suspension moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37); the rats in the medication group were treated with intragastric administration of rifaximin suspension (150 mg/kg). All the treatments were given once a day for 7 consecutive days. The body mass, loose stool rate (LSR), the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were measured before acetic acid enema (35 days old), after modeling (45 days old), and after intervention (53 days old). After intervention (53 days old), HE staining was used to observe the morphology of colon tissue, and spleen and thymus coefficients were measured; ELISA method was used to detect serum inflammatory factors (tumor necrosis factor a [TNF-a], interleukin [IL]-10, IL-8), T-lymphocyte subsets (CD+4, CD+8, CD+45), value of CD+4/CD+8 and immune globulin (IgA, IgG, IgM); real-time PCR method and Western blot method was used to detect the expression of SCF, c-kit mRNA and protein in colon tissue; immunofluorescence staining method were used to detect positive expression of SCF and c-kit. RESULTS After intervention, compared with the normal group, in the model group, the body mass and the minimum volume threshold when AWR scored 3 were decreased (P<0.01), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+45, CD+4/CD+8, IgA, IgG, IgM were increased (P<0.01), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were decreased (P<0.01), and the positive expression of SCF and c-kit was decreased (P<0.01). Compared with the model group, in the moxibustion group and the medication group, the body mass and the minimum volume threshold when AWR scored 3 were increased (P<0.01, P<0.05), LSR, spleen and thymus coefficients, serum levels of TNF-α, IL-8, CD+4, CD+8, CD+45, CD+4/CD+8, IgA, IgG, IgM were decreased (P<0.01, P<0.05), serum IL-10 level and protein and mRNA expression of SCF and c-kit in colon tissue were increased (P<0.01), and the positive expression of SCF and c-kit was increased (P<0.01). Compared with the medication group, in the moxibustion group, the level of serum CD+4 was decreased (P<0.05), the value of CD+4/CD+8 was increased (P<0.01), and there was no significant difference in other indexes (P>0.05). The expression of SCF and c-kit mRNA was positively correlated with the minimum volume threshold when AWR scored 3 and IL-10 (P<0.01), and negatively correlated with remaining indexes (P<0.01, P<0.05). CONCLUSION Moxibustion could reduce visceral hypersensitivity, improve symptoms of abdominal pain and diarrhea in IBS-D rats, and its mechanism may be related to up-regulation of the expression of SCF/c-kit signaling pathway and improvement of IBS-D immune function.

Abstract
OBJECTIVE To observe the effect of moxibustion on the regulation of nuclear factor-kappa B (NF-κB) and inflammatory factors by multiple microRNAs (miRNAs) in rats with diarrhea-predominant irritable bowel syndrome (IBS-D), and to explore the anti-inflammatory mechanism of moxibustion on IBS-D. METHODS Twelve of 52 newborn rats were randomly selected into a normal group. The remaining rats were made into IBS-D model. A total of 36 rats with successful model were randomly divided into a model group, a medication group and a moxibustion group, 12 rats in each group. The rats in the medication group were intraperitoneally injected with pyrrolidine dithiocarbamate (PDTC). The rats in the moxibustion group were treated with moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) for 20 min each time. All the intervention was given once a day for 7 days. Before and after modeling as well as after intervention, the body mass, loose stool rate and the minimum volume threshold of abdominal withdrawal reflex (AWR) were measured. After intervention, the contents of serum tumor necrosis factor α (TNF-α), interleukin (IL)-1β and IL-8 were detected by ELISA method; the morphology of colon tissues was observed by HE staining, and the expressions of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in colon tissues were detected by real-time PCR. The expressions of NF-κB p65, TNF-α, IL-1β and IL-8 protein in colon tissues were detected by immunofluorescence. RESULTS After modeling, the body mass and the minimum volume threshold of AWR in the model group were lower than those in the normal group (P<0.01); the rates of loose stool in the model group were higher than those in the normal group (P<0.01); after intervention, in the model group, the inflammatory infiltration of colon tissues was obvious, and the serum levels of TNF-α, IL-1 β, IL-8 were higher than those in the normal group (P<0.05); the expression of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in colon tissues was higher than that in the normal group (P<0.05); the protein expression of NF-κB p65, TNF-α, IL-1β, IL-8 was also higher than that in the normal group (P<0.01). After intervention, the body mass and the minimum volume threshold of AWR in the medication group and the moxibustion group were both higher than those in the model group (P<0.05); the loose stool rate in the medication group and the moxibustion group were lower than those in model group (P<0.05); the inflammatory cells infiltration in the colon tissues was less, the serum levels of TNF-α, IL-1β and IL-8 as well as the protein expression of NF-κB p65, TNF-α, IL-1β and IL-8 in the colon tissues in the medication group and the moxibustion group were lower than those in the model group (P<0.05, P<0.01). The expression of miR-125b, miR-31, miR-18a and NF-κB p65 mRNA in the medication group were lower than those in the model group (P<0.05). The expression of miR-155, miR-125b, miR-29b, miR-31, miR-18a and NF-κB p65 mRNA in the moxibustion group were lower than those in the model group (P<0.05). The miR-155, miR-125b, miR-29b, miR-31, miR-18a were positively correlated with NF-κB p65 mRNA (0<r<1, P<0.01). CONCLUSION The anti-inflammatory mechanism of moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) for IBS-D rats may be related to regulating multiple miRNAs to inhibit NF-κB signal pathway and reduce the expression of inflammatory factors.

Abstract
BACKGROUND Advanced prostate cancer etiology is poorly understood. Few studies have examined associations of anthropometric factors (e.g. early adulthood obesity) with advanced prostate cancer risk. PATIENTS AND METHODS We carried out pooled analyses to examine associations between body fatness, height, and prostate cancer risk. Among 830 772 men, 51 734 incident prostate cancer cases were identified, including 4762 advanced (T4/N1/M1 or prostate cancer deaths) cases, 2915 advanced restricted (same as advanced, but excluding localized cancers that resulted in death) cases, 9489 high-grade cases, and 3027 prostate cancer deaths. Cox proportional hazards models were used to calculate study-specific hazard ratios (HR) and 95% confidence intervals (CI); results were pooled using random effects models. RESULTS No statistically significant associations were observed for body mass index (BMI) in early adulthood for advanced, advanced restricted, and high-grade prostate cancer, and prostate cancer mortality. Positive associations were shown for BMI at baseline with advanced prostate cancer (HR = 1.30, 95% CI = 0.95-1.78) and prostate cancer mortality (HR = 1.52, 95% CI = 1.12-2.07) comparing BMI ≥35.0 kg/m2 with 21-22.9 kg/m2. When considering early adulthood and baseline BMI together, a 27% higher prostate cancer mortality risk (95% CI = 9% to 49%) was observed for men with BMI <25.0 kg/m2 in early adulthood and BMI ≥30.0 kg/m2 at baseline compared with BMI <25.0 kg/m2 in early adulthood and BMI <30.0 kg/m2 at baseline. Baseline waist circumference, comparing ≥110 cm with <90 cm, and waist-to-hip ratio, comparing ≥1.00 with <0.90, were associated with significant 14%-16% increases in high-grade prostate cancer risk and suggestive or significant 20%-39% increases in prostate cancer mortality risk. Height was associated with suggestive or significant 33%-56% risks of advanced or advanced restricted prostate cancer and prostate cancer mortality, comparing ≥1.90 m with <1.65 m. CONCLUSION Our findings suggest that height and total and central adiposity in mid-to-later adulthood, but not early adulthood adiposity, are associated with risk of advanced forms of prostate cancer. Thus, maintenance of healthy weight may help prevent advanced prostate cancer.

Abstract
Objective: To assess the effectiveness and safety of sacral neuromodulation (SNM) therapy for men with idiopathic dysuria. Methods: From January 2012 to December 2016, a total of 26 patients treated with SNM therapy from multi-center across the country were retrospectively studied. The age ranged from 19 to 86 years with an average age of 45.2 years. Patients suffered from one or multiple urinary symptoms such as frequency of urination, urgency, urinary retention, etc. All patients had received more than two types of conservative therapy including oral and behavioral therapy, but had poor or no improvement. The voiding diary, urgency score and the quality of life score before implantation, in stageⅠ after implantation and stage Ⅱ after permanent implantation were recorded and compared. Results: A total of 22 patients chose to receive IPG at the end of stageⅠ therapy while 4 patients refused further stage Ⅱ therapy because of dissatisfactory effect. The conversion rate of stage Ⅰ to stage Ⅱ was 84.6% (22/26). The average follow-up time was 19.2 months, ranging from 3 to 63 months. The baseline of residual urine, voiding frequency and average voiding amount and those after stage Ⅰ therapy were [5 (0, 137.5) ] ml vs [0 (0, 40) ] ml, 14.6±6.1 vs 9.1±2.8, [100 (80, 135) ] ml vs [190 (150, 210) ] ml, respectively. The differences were statistically significant(all P<0.05).However, no significant differences were found in urination volume and quality of life (QoL) before and after implantation(P>0.05). During an average follow-up time of 19.2 months after the permanent implantation, over 80% patients had an improvement of residual urine volume by more than 50% after permanent implantation while the improvement was 55.6% after stage Ⅰ therapy, suggesting that the improvement of residual urine volume might be positively correlated with the duration of regulation. No significant differences were found in other parameters between stage Ⅰ and Ⅱ therapy. No adverse events like wound infection and electrode dislocation happened during our study. Conclusions: SNM is an effective and safety procedure for male patients with idiopathic dysuria, with a relatively high transfer rate. The medium-term curative effect is stable. The duration of regulation may be positively correlated with the improvement of residual urine.

Abstract
OBJECTIVE To investigate the optimal starvation conditions of human umbilical vein endothelial cells (HUVECs) and establish a highly efficient and stable method for separating HUVECs. METHODS HUVECs harvested from human umbilical cords by digestion with 0.1% collagenase II for 15 min were cultured in endothelial culture medium (ECM) containing 5% fetal bovine serum (FBS), 1% endothelial cell growth factor (ECGS) and 1% penicillin/streptomycin solution(P/S) at 37 degrees celsius; in 5% CO2. The cells were observed for cell morphology under an inverted microscope and identified with immunofluorescence assay. The purity of HUVECs was detected using flow cytometry (FCM). The cell cycles of HUVECs cultured in the presence of 0, 0.1%, 0.5%, and 1% FBS for 0, 6, 12, 18, and 24 h were analyzed with flow cytometry. RESULTS s The purity of HUVECs harvested by digestion with 0.1% collagenase II reached 99.67%. The primary HUVECs showed a cobblestone or volute appearance in vitro. Immunocytochemistry showed that HUVECs highly expressed VIII-related antigen. Cell culture in the presence of different concentrations of FBS for 6 h resulted in 70% G0/G1 phase cells, which increased to 80%-90% at 12 h of cell culture, and further to around 95% at 18 and 24 h. CONCLUSION Digestion with 0.1% collagenase II can obtain high-purity primary HUVECs. Culturing HUVECs in serum-free medium for 12 h can result in a high purity (over 80%) of G0/G1 phase cells.

Abstract
This report is based on an audit of the delivery outcome of a specific care pathway for women who had made a maternal request for caesarean section (MRCS). The study took place in a UK inner city National Health Service maternity unit with 6,000 births per year. All 31 multiparous and 16 nulliparous women on the pathway were included. All of the former group had delivered vaginally, all reported having experienced their previous birth as traumatic, and all subsequently delivered vaginally. Of the 16 nulliparous women, six delivered by planned caesarean section; four delivered vaginally; four had an instrumental delivery and two had an emergency caesarean section. A designated multidisciplinary care pathway that incorporates education and support may have the potential to help more women to achieve a normal delivery. More research is needed to assess its potential for reducing unnecessary caesarean deliveries and for improving user experience.

Abstract
We investigated in vitro antioxidant activities of 49 endophytic fungi isolated from the liverwort Scapania verrucosa. Based on morphological and molecular identification, the endophytic fungi isolated were classified into seven genera (Hypocrea, Penicillium, Tolypocladium, Chaetomium, Xylaria, Nemania, and Creosphaeria), all belonging to one family (Xylariaceae). By screening with the 2,2'-azino-di(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) decolorization assay, the ethyl acetate extracts of five endophytic fungi (T7, T21, T24, T32, and T38 strains), which exhibited remarkable Trolox equivalent (TE) antioxidant capacity (ranging from 997.06 to 1248.10 μmol TE/g extract), were selected and their antioxidant capacity was further evaluated by assays for 2,2'-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging, hydroxyl radical scavenging, reducing power, and ferrous ion chelating. The ethyl acetate extracts of two endophytic fungi (T24 and T38) were found to have comparable scavenging abilities on both DPPH-free radicals (93.9 and 88.7%, respectively, at 50 μg/mL) and hydroxyl radicals (97.1 and 89.4%, respectively, at 2 mg/mL) when compared with those of the positive controls (ascorbic acid and butylated hydroxytoluene, respectively). Although their reducing powers were similar to that of butylated hydroxytoluene, as indicated by absorbance (0.35 and 0.30 at 50 μg/mL, respectively), only the T38 strain's ethyl acetate extract showed ferrous ion chelating ability (92.9% at 1 mg/mL) comparable to that of the EDTA-2Na control. These endophytic fungi in S. verrucosa are a potential novel source of natural antioxidants.

Abstract
AIM To comparatively evaluate the efficacy and post-operative complications of the Madigan's prostatectomy (MPC) and suprapubic prostatectomy (SPPC). METHODS A total of 43 patients with benign prostatic hyperplasia were divided into two groups: 21 underwent MPC and 22, SPPC. In all the patients, the international prostate symptom score (IPSS) and urinary pressure-flow studies were assessed before and 6 months after operation. The International Continence Society (ICS) nomogram, Abrams-Griffiths (AG) number and linear passive urethral resistance relation analysis (L-PURR) were used to diagnose and grade bladder outlet obstruction (BOO). The IPSS and the urodynamic parameters before and after operation, as well as the advantages and post-operative complications were recorded and compared. RESULTS Patients of both the MPC and SPPC groups had a significant improvement in IPSS and urodynamic parameters. Obstruction was relieved in 81.0% of MPC and 86.4% of SPPC patients. MPC has the advantages of the absence of postoperative hematuria and post-catheter stricture, a shorter period of hospitalization, and lower incidence of retrograde ejaculation and erectile dysfunction. CONCLUSION Both MPC and SPPC can effectively relieve BOO. MPC has certain advantages and a lower incidence of complications as compared with SPPC.

Abstract
The beta-NADPH histochemical method was used to study the effect of lead on activity of nitric oxide synthase(NOS) in neurons and vessel smooth muscles of intestinal wall in rats. The results showed that the number of NOS positive neurons and fibers was decreased and degenerative changes of some NOS positive neurons were found after the lead acetate intraperitoneal injection. The activity of NOS in the vessel smooth muscles was reduced. It suggests that lead colic may be induced by reduction of NO in the neurons which innervate the gut smooth muscles.

Abstract
AIM To study the behavior of external urethral sphincter in chronic prostatitis (CP) patient under natural filling. METHODS Twenty-one CP patients and 17 normal volunteers were involved in the study. Both the patients and volunteers underwent ambulatory urodynamic monitoring (AM) and conventional medium filling cystometry (CMG). Urodec 500 was used for AM and Menuet for CMG. AM findings from CP patients were compared with those from normal volunteers, and the results from AM were compared with those from CMG. RESULTS In AM, the resting and voiding external urethral sphincter (EUS) pressures and maximum urethral closure pressures (MUCP) were significantly higher in CP patients [(121.5 +/- 10.3) and (85. 6 +/- 3.5) cm water, respectively] than in normal volunteers [(77.6 +/- 11.4) and (10.3 + 1.6) cm water, respectively)]. CONCLUSION The behavioral changes of EUS in CP patients included spasm and instability of EUS, which were demonstrated using AM under natural filling; the findings were also in accord with the results of CMG.

Abstract
Polymerase chain reaction (PCR) amplification was set up with double primer pairs of major immediate-early and late gene in order to detect human cytomegalovirus (HCMV) from urine. This method was applied to the detection of HCMV in clinical samples of urine from renal transplant recipients. The result indicated that the primers did not cross react with other members of the herpes family of virus and human genomic DNA; that the HCMV AD169 tissue culture mixture used and the dilutions to estimate the sensitivity of PCR relative to tissue culture, 2.5 microliters of a 10(-3) dilution of the culture (625fg HCMV DNA) assayed were detected by direct gel analysis; that 25 of 30 samples of urine from the renal transplant recipients (serum HCMV IgM positive) were positive. It is conclude that PCR amplification is a valuable tool for diagnoses of HCMV infection in renal transplant recipients.

Abstract
Acute allograft glomerulopathy (AAG) is a distinctive glomerular lesion of renal allografts. Its clinical signs and symptoms, pathology and etiology were studied. The frequency of AAG was 57.6% in renal transplant recipients. The clinical signs and symptoms included urinary protein, cast, WBC and RBC, etc. The pathologic features were diffuse endothelial hypertrophy and necrosis accompanied by accumulation of periodic acid-schiff (PAS) positive material and mononuclear cells that resulted in obliteration of glomerular capillaries, basilar membrane proliferation and immune complexes deposition. To elucidate the pathogenesis of AAG, we diagnosed HCMV infection of renal transplantation recipients by using polymerase chain reaction (PCR) and ELISA. Circulating T cell subsets were detected with APAAP method. OR of AAG occurrence in HCMV infection group was 32.4 times as high as in non-HCMV infection one (P < 0.01). OR of AAG occurrence in CD4/CD8 < 1.5 group was 12 times as high as in CD4/CD8 > 1.5 one (P < 0.01); so AAG was strongly associated with HCMV infection and T cell subsets changes (decreased or inverted CD4/CD8 ratio) induced by HCMV.

Abstract
In mice, CI-930 0.5-2 mg.kg-1 ip not only prolonged the tail bleeding time but also protected the mice from sudden thromboembolic death induced by arachidonic acid (AA, 100 mg.kg-1, i.v.) or TXA2/PGH2 mimetic U46619 (200 micrograms.kg-1, i.v.). CI-930 0.625 and 2.5 mg.kg-1 i.v. exhibited a dose-dependent inhibitory effect on thrombus formation in rat arteriovenous shunt. All these effects of CI-930 were more potent than those of dazoxiben, a known antiplatelet drug. In rabbit, AA 0.75 mg.kg-1 i.v. caused a rapid and marked increase in pulmonary vascular resistance and a concomitant sharp decrease in cardiac output and carotid arterial pressure. CI-930 itself 0.5 mg.kg-1 i.v. resulted in a long-lasting fall in carotid arterial pressure, systemic vascular resistance, and a slight decrease in cardiac output. In addition, CI-930 protected rabbit from all the harmful hemodynamic responses to the occlusion of pulmonary microcirculation, which was induced by AA. The results suggest that CI-930 possess a potent anti-hemostatic, antithrombotic, and probably antihypertensive effects on experimental animals.
