OBJECTIVETo evaluate the clinical efficacy and safety of phosphodiesterase 5 (PDE-5) inhibitors for erectile dysfunction (ED) in patients with diabetes mellitus and provide some evidence for the clinical treatment of the disease.

METHODSWe searched MedMed, EMbase, Cochrane Library, CNKI, Wan Fang Data, VIP and ZADL for randomized controlled trials on PDE-5 inhibitors for ED in diabetic men and evaluated the methodology of the included trials with the Jadad scale. We used the erectile function domain in the IIEF (IIEF-EF), IIEF questions (IIEF-Q) 3 and 4, SEP-2 and -3, and Global Assessment Questions (GAQ) as the main evaluation indexes and employed the Review Manager 5. 1. 0 software for meta analysis.

RESULTSA total of 13 studies were included, which were all high quality trials with Jadad score > 3. The IIEF-EF scores in 10 of the included studies were subjected to meta analysis using the random-effect model (REM), with a weighted mean difference (WMD) of 5.64 (95% CI 4.41 - 6.83, P < 0.001). The fixed-effect model (FEM) analysis of the IIEF-Q scores in 6 of the studies showed the WMD to be 0.96 (95% CI 0.83 -1.08, P < 0.001) for IIEF-Q3 and 1.11 (95% CI 0.98 - 1.25, P < 0.001) for IIEF-Q4. FEM analysis of the SEP-2 scores showed WMD = 17.67 (95% CI 12. 38 - 22. 97, P < 0.001) in 2 of the studies, and that of the SEP-3 scores WMD = 23.64 (95% CI 17. 49 - 29.79, P < 0.001) in 5 of the studies. The GAQ scores in 11 of the studies were subjected to REM analysis, with OR = 6. 20 and 95% CI 3.65 - 10.52 (P < 0.001). REM analysis was performed on the adverse reactions in 11 of the studies, with OR = 7.43 and 95% CI 4.11 - 13.44 (P < 0.001).

CONCLUSIONPDE-5 inhibitors can effectively and safely improve erectile function in patients with diabetes mellitus.

An endophytic bacterium strain EBS05 from Cinamonum camphra was identified as Bacillus subtilis by morphological taxonomy and sequence analysis of 16S~23S rRNA intergenic spacer regions. Properties of antimicrobial compound produced by EBS05 were assayed. The active compound had the maximum absorbance peak at ?213.5 nm. The antimicrobial activity was stable in solution with pH value from 5 to 8, and decreased significantly in solution with pH value less than 4.0 or more than 9.0. The antimicrobial compound had thermodynamics stability. Its activity changed a little after treated at 60?C~80?C for two hours, and compared with 65% original activity after treated at 1?105 Pa for 30 minutes. The active substance had high resistance to ultraviolet radiation and protease K. Antimicrobial compound was soluble in alcohol solu- tion, which was easily dissolved in methanol and ethanol, but not dissolved in ethyl acetate, acetonitrile and petroleum et al.

OBJECTIVE: To investigate the position change of the fibular bone after maxillary reconstruction by free fibular flap and to analyze the factors affecting the position change. METHODS: Patients who underwent maxillary reconstruction by free fibular flap in the Department of Oral and Maxillofacial Surgery, Peking University School and Hospital of Stomatology from November 2012 to November 2016 were enrolled in this study. CT scans 1 week and 1 year postoperatively were collected and stored in DICOM format. The ProPlan CMF software was used to reconstruct the CT scans and separate the maxilla and each segment of the fibular flap. The Geomagic Control software was used to measure the long axis direction vector of each fibular segment. And the position change direction was recorded. The patients were divided into groups according to the use of the fibula or titanium plate to reconstruct the zygomaticmaxillary buttress. RESULTS: A total of 32 patients were enrolled. Among them, 21 were in the titanium plate group and 11 in the fibula bone group. The angle between the long axis of the fibular segment and the X axis in the X-Y plane was 95.65°±53.49° and 95.53°±52.77°, 1 week and 1 year postoperatively, and there was no statistical difference (P>0.05). The angle between the long axis of the fibular segment and the X axis in the X-Z plane was 96.88°±69.76° and 95.33°±67.42°, respectively, with statistical difference (P=0.0497). The angular changes of the long axis of the fibular segment in the titanium plate group and the fibular bone group were 3.23°±3.93° and 1.94°±1.78°, respectively, and the angular changes in the X-Z plane were 6.02°±9.89° and 3.27°±2.31°, respectively. There was no significant difference between the groups (P>0.05). The long axis changes of the fibular segment in the X-Y plane for reconstruction of the anterior alveolar, posterior alveolar, and buttress were 3.13°±3.78°, 2.56°±3.17°, and 5.51°±4.39°, respectively. There was a statistical difference (P = 0.023) between the posterior and buttress. In the X-Z plane, theses were 4.94°±4.75°, 5.26°±10.25°, 6.69°±6.52°, respectively. There was no statistical difference among the three groups (P>0.05). The main positional deviation directions of the titanium plate group and the fibular bone group were interior and superior sides, and there was no statistical difference between the two groups (P>0.05). CONCLUSION One year postoperatively, the position of the free fibular flap was changed compared with 1 week postoperatively. The position of the free fibular flap was mainly changed to the interior and superior sides.

OBJECTIVETo compare the efficacy of different points combination in the treatment of menopausal insomnia.

METHODSNinety-six cases of menopausal insomnia were randomized into 3 groups, Xinshu (BL 15), Shenshu (BL 23), Sishencong (EX-HN 1), Shenmen (HT 7), Sanyinjiao (SP 6) were chosen in the restore interaction between the heart and the kidney group (group A, 32 cases); Zhaohai (KI 6), Jiaoxin (KI 8), Shenmai (BL 62), Pucan (BL 61) were chosen in the acupuncturing qiao mai group (group B, 32 cases); auricular Shenmen (TF4) and sensitive spot at the distribution area of auricular vagus nervus were chosen in the ear acupuncture group (group C, 32 cases). Six days made one session and the treatments were finished after 4 courses. The polysomnography (PSG) and Pittsburgh sleep quality index (PSQI) were employed before and after treatment to evaluate the alleviation of insomnia.

RESULTSThe parameters of the sleep latency (SL), rapid wave sleep latency (RL) and sleep efficiency (SE) were significantly improved in the three groups, and the differences were statistically significant (P < 0.05, P < 0.01). The SL and awaking time (AT) in group C [SL (401.08 +/- 16.54) min and AT (4.87 +/- 2.64) times] were significantly superior to those in the other two groups [SL (50.36 +/- 18.47) min, (54.87 +/- 20.92) min, AT (5.98 +/- 2.11) times, (6.13 +/- 3.04) times, all P < 0.05]. The S(3+4) (%) in group C was also significantly higher than those in the other two groups (both P < 0.05). It was indicated by PSQI that the sleep quality of group C (0.78 +/- 0.12) was significantly superior to that in group B (1.32 +/- 0.29), the total score and cured and markedly effective rate in group C [(4.34 +/- 1.43), 68.8% (22/32)] were superior to those in group A [(7.48 +/- 3.09), 53.1% (17/32), both P < 0.05].

CONCLUSIONEar acupuncture has a better curative effect than the restore interaction between the heart and the kidney group and acupuncturing qiao mai group, it is worth of being promoted.

OBJECTIVETo observe the clinical efficacy on pain in postmenopausal osteoporosis treated with the warm acupuncture therapy and discuss its effect mechanism.

METHODSNinety cases of postmenopausal osteoporosis were randomized into a warm acupuncture group, an electroacupuncture group and a medication group, 30 cases in each group. In the warm acupuncture group and the electroacupuncture group, Dazhu (BL 11), Shenshu (BL 23) and Xuanzhong (GB 39) were selected bilaterally and stimulated with the warm acupuncture and electroacupuncture therapies respectively, once a day for 30 days totally. In the medication group, caltrate-D tablets were prescribed, 600 mg, once a day for 30 days totally. The changes in the bone density T value, visual analogue scale (VAS) score, serum insulin like growth factor 1 (IGF-1), interleukin 6 (IL-6) and tumor necrosis factor (TNF-alpha) were observed before and after treatment in the three groups.

RESULTS(1) The bone density T value in the patients of postmenopausal osteoporosis did not change obviously after 30 days treatment with the three therapies; (2) VAS score was all reduced after treatment, in which, the result in the warm acupuncture group was the most obvious (6.73 +/- 0.24 before treatment vs 4.43 +/- 0.26 after treatment). The value after treatment in the warm acupuncture group was different significantly as compared with the electroacupuncture group (5.13 +/- 0.31) and the medication group (5.17 +/- 0.33, both P < 0.05). (3) The level of serum IGF-1 was improved after treatment in the warm acupuncture therapy [(119.5 +/- 20.1) ng/mL before treatment vs (156.5 +/- 23.9) ng/mL after treatment], which was more apparent as compared with the electroacupuncture group [(136.3 +/- 24.5) ng/mL] and the medication group [(127.7 +/- 22.1) ng/mL, all P < 0.05]. Concerning to reducing the levels of IL-6 and TNF-alpha in serum, the results in the warm acupuncture group were superior to the other two groups (all P < 0.05).

CONCLUSIONThe warm acupuncture therapy achieves the significant efficacy on pain in postmenopausal osteoporosis, which could be related to increasing the level of IGF-1, decreasing the levels of IL-6 and TNF-alpha, promoting bone formation and inhibting bone absorption.

OBJECTIVETo investigate the protective effect of phosphodiesterase type 5 inhibitors (tadalafil) on the testis following testicular ischemia-reperfusion injury in rats.

METHODSEighty-four healthy adult male SD rats were randomly and equally divided into groups A (sham operation), B (testicular torsion + low-dose tadalafil), C (testicular torsion + high-dose tadalafil), and D (testicular torsion + placebo). Models were established in the latter three groups by 7200 torsion of the right testis for 2 hours. The animals in groups A and B were treated by gavage with tadalafil at the dose of 0. 5 mg per kg per day, those in group C at 2 mg per kg per day, and those in group D with saline at the same dose. After 3, 7, and 14 days of treatment, the torsioned testes were harvested for evaluation of the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis tissue. The pathological changes in the testis were observed under the light microscope.

RESULTSAt 3, 7, and 14 days, the SOD activity was (254.46 +/- 7.43), (278.49 +/- 8.33), and (317.99 +/- 3.31) nU/mg prot in group B, and (277.12 +/- 8.80), (309.40 +/- 2.14), and (320.39 +/- 4.72) nU/mg prot in group C, all obviously higher than in D ([223.21 +/- 4.65], [231.45 +/- 4.16] and [248.28 +/- 5.74] nU/mg prot), while the MDA content was lower in the former two groups than in the latter. At 3 and 7 days, the SOD activity was significantly higher and the MDA level significantly lower in group C than in B (both P < 0.01) , while at 14 days, neither showed any remarkable differences between the two groups (P > 0.05). No obvious histopathological change was observed in the testis tissue of group A. At 3 and 7 days, pathological examination of the testis tissue revealed significant differences in the number of seminiferous epithelial layers, testicular histological score, and seminiferous tubule diameter in group B (P < 0.01), but the three indexes at 14 days in group B and at 7 days in group C exhibited no remarkable differences from those at 14 days in group A.

CONCLUSIONTadalafil can alleviate testicular ischemia-reperfusion injury following testis torsion/detorsion in a time- and dose-dependent manner.
