[Tonglong Kaibi Prescription for the treatment of severe benign prostate hyperplasia: A clinical study].

OBJECTIVE: To evaluate the clinical effect of the traditional Chinese medicine (TCM) Tonglong Kaibi Prescription (TKP) in the treatment of severe BPH with kidney deficiency and blood stasis combined with damp heat syndrome. METHODS: We randomly divided 120 cases of severe BPH with kidney deficiency and blood stasis combined with damp heat syndrome into three groups of equal number, treated with TKP, doxazosin mesylate sustained-release tablets (the DM control), and TKP + DM, all for 8 weeks. We obtained the IPSS, TCM symptoms scores, quality of life (QOL) scores, maximum urinary flow rate (Qmax) and postvoid residual urine volume (PVR) from the patients before and after treatment and compared them among the three groups. RESULTS: After 8 weeks of treatment, the effectiveness rate was significantly higher in the TKP + DM than in the DM control group (P < 0.05). The IPSS, TCM symptoms scores, QOL scores and PVR decreased (P < 0.01), while the Qmax increased dramatically (P < 0.01) in all the three groups. Pairwise comparison showed that the IPSS and QOL scores were lower in the TKP + DM than in the TKP and DM control groups (P < 0.05 or 0.01), and so were the TCM syndrome scores in the TKP + DM and TKP groups than in the DM control (P < 0.01). There were no statistically significant differences in PVR and Qmax among the three groups after treatment (P> 0.05), and no serious adverse events during the treatment. CONCLUSION: TKP is safe and effective in the treatment of severe BPH, which can improve the TCM symptoms, reduce the IPSS, QOL scores and PVR and increase the Qmax of the patients. TKP is evidently superior to DM alone in improving TCM symptoms of BPH and combined medication of TKP and DM produces even better clinical efficacy.

[Pricking-reinforcing -reducing therapy improves semen quality and seminal plasma biochemical indexes in patients with varicocele infertility].

OBJECTIVE: To investigate the effect of pricking-reinforcing -reducing therapy (PRRT) on the semen quality and seminal plasma biochemical indexes of varicocele (VC) infertility patients. METHODS: We randomly and equally assigned 160 patients with VC infertility into a PRRT and a control group, the former treated by PRRT and the latter with oral ShengjingCapsules. Before and after treatment, we obtained the semen parameters, sperm morphology, sperm survival rate, sperm acrosin activity, seminal plasma neutral α glucosidase and seminal plasma zinc in the patients and compared them between the two groups. RESULTS: Before treatment, there were no statistically significant differences between the PRRT and control groups in sperm concentration (ï¼»16.81 ± 7.83ï¼½ vs ï¼»16.80 ± 7.54ï¼½ ×106 /ml, P > 0.05), total sperm count (ï¼»42.01 ± 19.57ï¼½ vs ï¼»41.99 ± 18.84ï¼½ ×106, P > 0.05), percentages of progressively motile sperm (PMS) (ï¼»15.37 ± 11.03ï¼½% vs ï¼»14.68 ± 10.27ï¼½%, P > 0.05) and morphologically normal sperm ( MNS) (1.62 ± 1.51ï¼½% vs ï¼»1.62 ± 1.13ï¼½%, P > 0.05), sperm survival rate (ï¼»28.11 ± 18.95ï¼½% vs ï¼»28.23±18.38ï¼½%, P > 0.05) and sperm acrosin activity (ï¼»28.11 ± 14.64ï¼½ vs ï¼»27.19 ± 14.07ï¼½ U/L, P > 0.05). After three months of treatment, all the patients showed evident increases in the above parameters (P < 0.05), even higher in the PRRT than in the control group, more significantly in sperm concentration (ï¼»38.88 ± 30.54ï¼½ vs ï¼»25.60 ± 14.71ï¼½ ×106 /ml, P < 0.05), PMS (ï¼»32.60 ± 12.46ï¼½% vs ï¼»27.67 ± 12.27ï¼½%, P < 0.05) and sperm acrosin activity (ï¼»65.74±31.81ï¼½ vs ï¼»67.94±17.95ï¼½ U/L, P < 0.05), though not significantly in total sperm count (97.20 ± 76.35ï¼½ vs ï¼»88.19 ± 39.56ï¼½ ×106, P > 0.05), MNS (ï¼»2.35 ± 1.83ï¼½% vs ï¼»1.87 ± 1.20ï¼½%, P > 0.05) and sperm survival rate (ï¼»61.44 ± 20.02ï¼½% vs ï¼»59.12 ± 22.48ï¼½%, P > 0.05). Compared with the baseline, after treatment, the patients in the PRRT group also exhibited elevated levels of neutral α-glucosidase (ï¼»14.42 ± 5.90ï¼½ vs ï¼»28.43 ± 19.76ï¼½ U/L, P < 0.05) and seminal plasma zinc (ï¼»2.11 ± 1.22ï¼½ vs ï¼»2.89 ± 1.23ï¼½ mmol/L, P < 0.05), and so did the controls (ï¼»14.44 ± 5.61ï¼½ vs ï¼»26.66 ± 17.69ï¼½ U/L , P < 0.05) and (ï¼»2.09 ± 1.10ï¼½ vs ï¼»2.82±1.08ï¼½ mmol/L, P < 0.05). No statistically significant difference, however, was observed between the two groups after treatment (P > 0.05). CONCLUSION: PRRT can significantly improve semen quality in patients with VC infertility, even more effective than ShengjingCapsules in improving sperm concentration, PMS, sperm survival rate, and sperm acrosin activity, which may be related to its effect of elevating the levels of seminal plasma neutral-α glucosidase and zinc providing sufficient energy for basic sperm metabolism, maturation, energy acquisition and motility.

[Danhong Tongjing Prescription versus microsurgery in the treatment of varicocele-induced infertility: A retrospective multivariate analysis of 218 cases].

OBJECTIVE: To compared the traditional Chinese medicine Danhong Tongjing Prescription (DTP) and microsurgery in the treatment of varicocele (VC)-induced infertility and investigate the factors influencing the recovery of semen parameters of the patients. METHODS: We retrospectively analyzed the clinical data on 218 cases of VC-induced infertility with qi-deficiency and blood-stasis treated with DTP (n = 86) or by microsurgery (n = 132) in our hospital from January 2017 to July 2019, and compared the semen parameters between the two groups of patients after treatment. With age, course of disease, degree of VC, change of the testis volume, estrogen/testosterone (E/T) ratio and levels of FSH and LH as independent variables, and increased semen parameters after treatment as dependent variables, we constructed a multivariate linear regression model and identified statistically significant independent variables. RESULTS: After treatment, sperm concentration and the percentages of progressively motile sperm (PMS) and morphologically normal sperm (MNS) were obviously improved in both the DTP and microsurgery groups, with statistically significant difference between the two groups in sperm concentration and MNS, but not in PMS. Linear regression analysis showed that the severity of VC was an influencing factor for the recovery of sperm concentration after treatment in the DTP group (r = －11.599, Ra2 = 0.044 9) and the course of VC infertility was a factor affecting the recovery of sperm count in the microsurgery group (r = －1.837, Ra2 = 0.035 7). CONCLUSION: DTP is comparable to microsurgery in improving sperm motility while microsurgery is more effective in increasing the percentage of MNS in the treatment of VC-induced infertility. Early surgery is recommended for the treatment of infertility induced by severe bilateral VC, and DTP can be selected for infertility caused by mild or moderate bilateral VC if the patient is unwilling to accept surgery or microsurgery is inaccessible in the hospital.

[Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription for the treatment of CP/CPPS and its effects on secretory IgA, vascular cell adhesion molecule-1 and interleukin-8].

OBJECTIVE: To investigate the therapeutic effect of magnetic resonance and magnetoelectric therapy (MRMT) combined with oral Danhong Tongjing Prescription (DTP) on chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS) and the changes in the levels of cytokine-secretory IgA (sIgA), vascular cell adhesion molecule-1 (VCAM-1) and interleukin-8 (IL-8) after treatment. METHODS: Totally 200 patients with CP/CPPS of the qi stagnation and blood stasis type were randomly divided into three groups to receive MRMT + DTP (n = 68), MRMT (n = 67) and DTP (n = 65), respectively, all for 12 weeks. After treatment, we compared the total effectiveness rate, patients' scores on NIH-CPSI and traditional Chinese medicine (TCM) syndrome, and the expressions of sIgA, VCAM-1 and IL-8 in the EPS among the three groups of the patients. RESULTS: After treatment, the patients in the MRMT + DTP group, compared with those in the MRMT and DTP groups, showed a significantly higher total effectiveness rate (86.76% vs 79.10% and 78.46%, P < 0.05 and P < 0.01) and lower scores on pain or discomfort (4.61 ± 2.37 vs 5.86 ± 3.26 and 6.94 ± 2.25 P < 0.01), abnormal urination symptoms (2.98 ± 1.75 vs 3.85 ± 2.01 and 3.94 ± 1.95) and quality of life (3.26 ± 1.87 vs 4.54 ± 2.13 and 4.69 ± 1.72). There were statistically significant differences in the total NIH-CPSI scores among the three groups (10.64 ± 5.91 vs 4.59 ± 6.87 vs 15.54 ± 5.76, P < 0.05). The MRMT + DTP group also exhibited a remarkably lower TCM syndrome score than the MRMT and DTP groups (5.56 ± 3.42 vs 7.37 ± 4.57 and 8.16 ± 3.65, P < 0.05). Compared with the baseline, the expressions sIgA, VCAM-1 and IL8 were all markedly decreased after treatment in the MRMT + DTP (Z = －7.170, Z = －7.182, Z = －7.18), MRMT (Z = －6.802, Z = －6.973, Z = －6.768) and DTP groups (Z = －5.963, Z = －6.990 Z = －5.618) (P < 0.05), even more significantly in the former than in the latter two groups (P < 0.05). CONCLUSION: Magnetic resonance and magnetoelectric therapy combined with Danhong Tongjing Prescription has a good therapeutic effect on CP/CPPS of the qi stagnation and blood stasis type, probably by regulating sIgA, VCAM-1, IL-8 and other cytokines, activating the function of the immune system, inhibiting inflammation, and promoting the absorption of local inflammatory substances.

[Danhong Tongjing Prescription improves sperm quality in patients with bilateral varicocele after varicocelectomy].

OBJECTIVE: To investigate the effect of Danhong Tongjing Prescription (DTP) on sperm quality in patients with bilateral varicocele (VC) after microsurgical varicocelectomy. METHODS: We randomly assigned 68 patients with bilateral VC to receive microsurgical varicocelectomy (the control group, n = 34) or microsurgical varicocelectomy followed by oral administration of DTP for a course of 90 days (the DTP group, n = 34). Before and after treatment, we obtained the sperm concentration, total sperm count, total sperm motility, the percentage of progressively motile sperm (PMS), sperm acrosomal enzyme activity, inhibin B (Inh-B) level, and sperm DNA fragmentation index (DFI) from the patients and compared the parameters between the two groups. RESULTS: There were no statistically significant differences in sperm concentration, PMS, acrosomal enzyme activity or sperm DFI among the patients with different degrees of VC preoperatively. After 3 months of medication, sperm concentration, total sperm count, total sperm motility, PMS and acrosomal enzyme activity were all increased while DFI decreased in both the control and DTP groups, even more significantly in the DTP group than in the control, and the Inh-B level was also markedly elevated in the DTP group in comparison with the baseline. CONCLUSIONS: The severity of bilateral VC is not correlated with the reduction of semen quality. DTP can improve sperm quality by improving total sperm count, PMS and acrosomal enzyme activity and reducing DFI in VC patients after varicocelectomy. The underlying mechanisms of the prescription may be related to its anti-oxidative stress action and abilities of improving reproductive hypoxia, spermatogenic environment and the function of Sertoli cells, but the specific signaling pathway involved is not yet clear.

[Lingze Tablets for BPH with kidney-deficiency, blood stasis and dampness resistance: A phase-â £ open-label single-arm multicenter clinical study and safety evaluation].

OBJECTIVE: To evaluate the efficacy and safety of Lingze Tablets in the treatment of BPH with kidney deficiency, blood stasis and dampness resistance. METHODS: Totally 235 eligible BPH patients, aged 50－80 years and meeting the inclusion criteria, were enrolled and treated with Lingze Tablets orally, 4 tablets per time, tid. Before and after an 8-week course of medication, IPSS, quality of life (QOL) and TCM syndromes scores were obtained from the patients. RESULTS: Of the total number of patients, 211 completed the whole course of treatment. Compared with the baseline, the IPSS was dramatically reduced after 4 and 8 weeks of medication (18.28 ± 5.29 vs 12.82 ± 4.66 and 9.23 ± 4.21, P < 0.01), and so were the QOL scores (6.44 ± 1.99 vs 4.95 ± 1.64 and 3.16 ± 1.53, P < 0.01) and TCM syndromes scores (17.49 ± 5.30 vs 12.45 ± 3.74 and 9.17 ± 3.24, P < 0.01). The incidence rates of adverse events and drug-related adverse reactions were 15.2% and 1.9%, respectively, and no organ function impairment was observed. CONCLUSIONS: Lingze Tablets are definitely effective and safe for the treatment of BPH with kidney deficiency, blood stasis and dampness resistance.

Limited Clinical Utility of Remote Ischemic Conditioning in Renal Transplantation: A Meta-Analysis of Randomized Controlled Trials.

OBJECTIVE: We conducted this meta-analysis of randomized controlled trials (RCTs) to investigate whether remote ischemic conditioning (RIC) could improve graft functions in kidney transplantation. METHODS: PubMed, Web of Science, and Cochrane Library were comprehensively searched to identify all eligible studies by October 5, 2016. The treatment effects were examined with risk ratio (RR) and weighted mean difference with the corresponding 95% confidence intervals (CI). The statistical significance and heterogeneity were assessed with both Z-test and Q-test. RESULTS: A total of six RCTs including 651 recipients, were eventually identified. Compared to the controls, RIC could reduce the incidence of delayed graft function (DGF) after kidney transplantation (random-effects model: RR = 0.89; fixed-effect model: RR = 0.84). However, the decrease did not reveal statistical significance. The subgroup analysis by RIC type demonstrated no significant difference among the three interventions in protecting renal allografts against DGF. Furthermore, no significant difference could be observed in the incidence of acute rejection, graft loss, 50% fall in serum creatinine, as well as the estimated glomerular filtration rate and hospital stay between the RIC and Control groups. CONCLUSIONS: This meta-analysis suggested that RIC might exert renoprotective functions in human kidney transplantation, and further well-designed RCTs with large sample size are warranted to assess its clinical efficacy.

MicroRNA expression profiles in muscle-invasive bladder cancer: identification of a four-microRNA signature associated with patient survival.

Bladder cancer ranks the second most common genitourinary tract cancer, and muscle-invasive bladder cancer (MIBC) accounts for approximately 25 % of all bladder cancer cases with high mortality. In the current study, with a total of 202 treatment-naïve primary MIBC patients identified from The Cancer Genome Atlas dataset, we comprehensively analyzed the genome-wide microRNA (miRNA) expression profiles in MIBC, with the aim to investigate the relationship of miRNA expression with the progression and prognosis of MIBC, and generate a miRNA signature of prognostic capabilities. In the progression-related miRNA profiles, a total of 47, 16, 3, and 84 miRNAs were selected for pathologic T, N, M, and histologic grade, respectively. Of the eight most important progression-related miRNAs, four (let-7c, mir-125b-1, mir-193a, and mir-99a) were significantly associated with survival of patients with MIBC. Finally, a four-miRNA signature was generated and proven as a promising prognostic parameter. In summary, this study identified the specific miRNAs associated with the progression and aggressiveness of MIBC and a four-miRNA signature as a promising prognostic parameter of MIBC.

Expression Profiles and Clinical Significance of MicroRNAs in Papillary Renal Cell Carcinoma: A STROBE-Compliant Observational Study.

Papillary renal cell carcinoma (pRCC) is the second most prevalent subtype of kidney cancers. In the current study, we analyzed the global microRNA (miRNA) expression profiles in pRCC, with the aim to evaluate the relationship of miRNA expression with the progression and prognosis of pRCC.A total of 163 treatment-naïve primary pRCC patients were identified from the Cancer Genome Atlas dataset and included in this retrospective observational study. The miRNA expression profiles were graded by tumor-node-metastasis information, and compared between histologic subtypes. Furthermore, the training-validation approach was applied to identify miRNAs of prognostic values, with the aid of Kaplan-Meier survival, and univariate and multivariate Cox regression analyses. Finally, the online DAVID (Database for Annotation, Visualization, and Integrated Discover) program was applied for the pathway enrichment analysis with the target genes of prognosis-associated miRNAs, which were predicted by 3 computational algorithms (PicTar, TargetScan, and Miranda).In the progression-related miRNA profiles, 26 miRNAs were selected for pathologic stage, 28 for pathologic T, 16 for lymph node status, 3 for metastasis status, and 32 for histologic types, respectively. In the training stage, the expression levels of 12 miRNAs (mir-134, mir-379, mir-127, mir-452, mir-199a, mir-200c, mir-141, mir-3074, mir-1468, mir-181c, mir-1180, and mir-34a) were significantly associated with patient survival, whereas mir-200c, mir-127, mir-34a, and mir-181c were identified by multivariate Cox regression analyses as potential independent prognostic factors in pRCC. Subsequently, mir-200c, mir-127, and mir-34a were confirmed to be significantly correlated with patient survival in the validation stage. Finally, target gene prediction analysis identified a total of 113 target genes for mir-200c, 37 for mir-127, and 180 for mir-34a, which further generated 15 molecular pathways.Our results identified the specific miRNAs associated with the progression and aggressiveness of pRCC, and 3 miRNAs (mir-200c, mir-127, and mir-34a) as promising prognostic factors of pRCC.
