Objective To investigate the effects of epithelial transformation sequence 2(ECT2)and p33ING1 on the metastatic activity of esophageal squamous cell carcinoma(ESCC)cells.Methods The expressions of ECT2 and p33ING1 in esophageal squamous cell carcinoma tissues and adjacent tissues were detected by immunohistochemistry and Western blotting.Human esophageal squamous carcinoma cell line KYSE140 cells were divided into 4 groups:blank group,negative control(pcDNA 3.1 NC)group,overexpression group(pcDNA 3.1 ECT2)and inhibited expression group(si ECT2).MTT assay and cell colony formation assay were used to study the proliferation and growth ability of cells,Transwell assay and scratch assay used to study the invasion and migration ability of cells,and flow cytometry used to detect apoptosis and cell cycle,Western blotting used to detect the effect of ECT2 on p33ING1 protein.Results ECT2 expression increased and p33ING1 expression decreased in esophageal squamous cell carcinoma tissues.Overexpression of ECT2 significantly increased the growth,colony formation,migration and invasion abilities of KYSE140 cells,and decreased the apoptosis rate and p33ING1 expression of KYSE140 cells.In addition,inhibition of ECT2 expression could reverse the above changes.Conclusion The high expression of ECT2 can promote the growth and metastasis of esophageal squamous cell carcinoma KYSE140 cells and inhibit their apoptosis.The mechanism may be related to the inhibition of p33ING1 expression by ECT2.

Erectile dysfunction (ED) is a common male disease. Some related studies show that the prevalence of ED is nearly 52% in men aged 40 to 70 years and is increasing among younger males. Hypoxia is now considered to be an independent risk factor for ED and the mechanisms of hypoxia inducing ED are varied and complicated. Recently, an idea in penile rehabilitation has attracted much attention, which aims at improving erectile function by increasing oxygen supply to the cavernosum and reducing tissue fibrosis and apoptosis. The approaches to achieve non-sexual penile erection by increasing oxygen supply to the cavernosum, such as behavior therapy, medication, vacuum constriction device, and intracavernous injection, can simulate normal sexual erection and help patients with penile rehabilitation. This review focuses on the strategies for non-sexual penile erection in penile rehabilitation.

ObjectiveTo evaluate the effect of ejaculatory duct dilation combined with seminal vesicle clysis in the treatment of refractory hematospermia.

METHODSUsing ureteroscopy, we treated 32 patients with refractory hematospermia by transurethral dilation of the ejaculatory duct combined with clysis of the seminal vesicle with diluent gentamicin.

RESULTSThe operation was successfully accomplished in 31 cases, with the mean operation time of 32 (26－47) minutes. The patients were followed up for 6－39 (mean 23.6) months. No complications, such as urinary incontinence and retrograde ejaculation, were found after operation. Hematospermia completely disappeared in 27 cases, was relieved in 1, and recurred in 3 after 3 months postoperatively. Those with erectile dysfunction or mental anxiety symptoms showed significantly decreased scores of IIEF-Erectile Function (IIEF-EF) and Self-Rating Anxiety Scale (SAS).

CONCLUSIONSEjaculatory duct dilation combined with seminal vesicle clysis under the ureteroscope, with its the advantages of high effectiveness and safety, minimal invasiveness, few complications, and easy operation, deserves general clinical application in the treatment of refractory hematospermia.

ObjectiveTo investigate the effect of salidroside on the expression of the connexin43 (Cx43) protein in the corpus cavernosum smooth muscle cells (CCSMCs) of hypoxic SD rats.

METHODSCCSMCs were cultured in vitro and identified by immunofluorescence staining. The cells were divided into six groups: normal control (21% O2), hypoxia (1% O2), hypoxia+salidroside (HS) 8 μg/ml,HS 16 μg/ml, HS 32 μg/ml, and HS 64 μg/ml, and cultured for 48 hours. Then the relative expression of Cx43 in different groups was detected by Western blot.

RESULTSThe in vitro cultured CCSMCs grew well and 90% of the cells showed positivity for α-SMA and desmin on immunohistochemistry. Salidroside ≤64 μg/ml produced no obvious toxicity on the CCSMCs. The expressions of Cx43 and phosphorylated proteins were dramatically increased in the hypoxia group as compared with the normal control (P<0.01 and P<0.05). The HS groups all showed significantly higher expression of Cx43 than the hypoxia group (P<0.01), but the phosphorylation rate of the Cx43 proteins was remarkably decreased (P<0.01).

CONCLUSIONSHypoxia increases the expression of Cx43 in the CCSMCs of SD rats. Salidroside ≤64 μg/ml cannot reverse the hypoxia-induced change but can reduce the dephosphorylation of Cx43 in CCSMCs. It is deduced that salidroside can protect CCSMCs by decreasing the phosphorylation of Cx43 and suppressing hypoxia-induced formation of the gap junction channel.

Objective To analyze the clinicopathological characteristics and the prognostic survival factors of young patients who have undergone hepatectomy for primary hepatic carcinoma.Methods Clinicopathological da-ta and treatment outcomes in 79 young (≤40 years old)and 67 elderly (≥65 years old)patients who underwent hep-atectomy for primary hepatic carcinoma between 2008 and 2012 were retrospectively collected and compared using various parameters.Then the survival rate and prognostic factors of the younger patients were analyzed using Kap-lan-Meier and COX multivariate proportional hazards model.Results The positive rate of HBs-antigen and alpha-fetoprotein level were significantly higher in the younger patients than in the elderly patients (P<0.05).However, the positive rate of Anti-HCV-Ab was markedly lower in the younger patients (P<0 .0 5 ).The two groups did not significantly differ in gender,clinical symptoms,intraoperative parameters or pathological features (P>0.05).The overall survival rate was similar between the two groups.COX multivariate proportional hazards model analysis showed that the independent prognostic factors of overall survival were pre-operative albumin level <3 5 g/L and maximum tumor diameter ≥5 cm.Conclusion Hepatectomy is a safe and feasible treatment for young and elderly patients with primary hepatic carcinoma.The independent prognostic factors of survival for young patients are pre-operative albumin level <3 5 g/L and the maximum tumor diameter ≥5 cm.

OBJECTIVETo investigate the effect of salidroside on hypoxia-induced apoptosis of corpus cavernosum smooth muscle cells (CCSMCs) in rats.

METHODSRat CCSMCs were cultured in vitro by the enzyme digestion method and identified by immunofluorescent staining of anti-alpha-SMA and anti-Desmin. The non-toxic dose of salidroside was determined by MTT assay. Low-oxygen mixed gas (1% O2, 5% CO2, and 94% N2) was piped into a modular incubator chamber to induce hypoxia. The CCSMCs were divided into a normal, a hypoxia, and a 32 microg/mL salidroside intervention group. The apoptosis of the CCSMCs was detected by flow cytometry and the expression of the caspase-3 protein determined by Western blot.

RESULTSThe majority of the CCSMCs were positive for alpha-SMA and Desmin at immunofluorescent staining. Salidroside at < 32 microg/ml produced no obvious toxicity to CCSMCs. Compared with the normal control group, the rates of early and late apoptosis of CCSMCs were both increased significantly in the hypoxia group ([12.77 +/-1.41]% vs [18.69 +/- 1.29]%, P < 0.01 and [14.63 +/- 2.00]% vs [21.03 +/- 1.530]% , P < 0.05). Western blot showed a markedly increased expression of cleaved caspase-3 (P < 0.01). Intervention with 32 microg/ml salidroside significantly reduced hypoxia-induced early apoptosis of CCSMCs ([13.46% +/- 1.87]%, P < 0.01) and decreased the expression of cleaved caspase-3 (P < 0.01).

CONCLUSIONSalidroside can reduce the expression of cleaved caspase-3 and inhibit hypoxia-induced apoptosis of CCSMCs in rats.

OBJECTIVETo observe the clinical effect of low-dose once-daily tadalafil combined with Shuganyiyang Capsules in the treatment of mild-to-moderate erectile dysfunction (ED).

METHODSNinety patients with mild-to-moderate ED were equally randomized to groups A, B and C to receive Shuganyiyang Capsules, tadalafil, and tadalafil + Shuganyiyang Capsules, respectively. The scores of the patients on IIEF-5 and SF-PAIRS (15-Item Short Form of Psychological Interpersonal Relationship Scales) were recorded before and at 1 and 3 months after treatment.

RESULTSThe IIEF-5 scores of groups A, B and C were 10.13 +/- 1.55, 11.00 + 1.60 and 10.73 +/- 1.91 before treatment, and 13.77 +/- 2.11, 17.77 +/- 2.13 and 17.17 +/- 3.84 at 1 month after treatment, significantly higher in B and C than in A (P <0. 001) , but with no remarkable difference between B and C (P =0. 411). At 3 months after treatment, the IIEF-5 scores were 15.77 +/- 2.05, 18.07 +/- 2.24 and 19.37 +/- 3.76 in the three groups, dramatically higher in B and C than in A (P <0.001) as well as in C than in B (P<0.05). The scores on sexual self-confidence, sexual spontaneity and time concerns in SF-PAIRS were 3.90 +/-0.80, 8.67 +/- 1.94 and 14.43 +/- 1.92 before medication, 5.83 +/- 1.02, 9.90 +/- 1.75 and 11.17 +/- 1.68 at 1 month and 6.73 +/- 0.98, 11.07 +/- 2.08 and 10.67 +/-1.60 at 3 months after medication in group A; 4.17 +/- 0.87, 9.37 +/-1.43 and 14.47 +/-1.57 before medication, 6.47 +/-0.78, 10.83 +/- 2.18 and 10.20 +/-1.56 at 1 month and 6.83 +/-0.91, 11.30 +/- 1.88 and 9.47 +/- 1.57 at 3 months in group B; and 4.23 +/-0. 94, 9.50 +/- 1.89 and 14.67 +/- 2.91 before medication, 8.03 +/- 1.67, 13.43 +/-1.10 and 9.70 +/-1.21 at 1 month and 8.93 +/- 1.78, 14.70 +/- 1.26 and 8. 87 +/- 0. 97 at 3 months in group C. Compared with the baseline, the SF-PAIRS scores of the three groups were all significantly improved after treatment (P <0. 05) , and markedly higher in C than in the other two groups (P <0.05).

CONCLUSIONLow-dose once-daily tadalafil combined with Shuganyiyang Capsules is obviously effective in the treatment of mild-to-moderate ED, which not only improves the patients'erectile function, sexual self-confidence and sexual spontaneity, but also reduces their time concerns.

OBJECTIVETo explore the effects of salidroside on the phenotypic modulation of corpus cavernosum smooth muscle cells (CCSMC) in hypoxic SD rats.

METHODSCCSMCs were cultured in vitro and identified by immunohistochemistry. The cells were divided into six groups: normal control (21% O2), hypoxia (1% O2), hypoxia + salidroside 1 mg/L, hypoxia + salidroside 3 mg/L, hypoxia + salidroside 5 mg/L and hypoxia + PGE1 0.4 microg/L, and then cultured for 48 hours. The relative expressions of alpha-actin and osteopontin (OPN) in each group were determined by RT-PCR.

RESULTSThe in vitro cultured CCSMCs grew well, with anti-alpha-smooth muscle actin monoclonal antibodies immunohistochemically positive. The relative expression of alpha-actin was markedly decreased while that of OPN remarkably increased in the hypoxia group as compared with the normal control group (P < 0.01). The hypoxia + salidroside 5 mg/L group showed a significantly higher expression of alpha-actin and lower expression of OPN than the hypoxia group (P < 0.01), but exhibited no significant differences from the hypoxia + PGE group (P > 0.05).

CONCLUSIONHypoxia can reduce the relative expression level of alpha-actin and increase that of OPN in the CCSMCs of SD rats, namely, induce their phenotypic modulation from the contraction to the non-contraction type. Salidroside can restrain hypoxia-induced phenotypic modulation of CCSMCs, and its inhibitory effect at 5 mg/L is similar to that of PGE1.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.
