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.

AIM: To evaluate the anatomic and visual outcomes of 25-gauge vitrectomies combined with air tamponade for the treatment of idiopathic macular hole (IMH).METHODS: Thirty eyes of 27 patients with IMH were included in this prospective interventional study.All patients underwent 25-gauge pars plana vitrectomy (PPV) combined with phacoemulsification and air tamponade.Best corrected visual acuity (BCVA, logMAR), perimetry and multifocal electroretinography (mfERG) were conducted before and after the operation.Anatomical changes were evaluated with optical coherence tomography (OCT).RESULTS: The macular holes closed successfully in 28 eyes after the primary vitrectomy.The mean BCVA improved from 0.72±0.22 logMAR preoperatively to 0.29±0.18 logMAR postoperatively (P<0.001).In the visual field of central 10°, the average mean deviation (MD) decreased from-3.59±1.83 dB preoperatively to-2.51±1.36 dB postoperatively (P<0.001) and the average pattern standard deviation (PSD) decreased from 1.86±0.68 dB preoperatively to 1.33±0.32 dB postoperatively (P=0.001).The retinal response densities of mfERG in the foveal and perifoveal area increased significantly, and implicit times of rings 4-6 prolonged significantly (P<0.05).The symptom duration and baseline N1 amplitude densities at ring 1 had a significant impact on postoperative BCVA (P<0.001, P=0.001, respectively).CONCLUSION: The 25-gauge PPV and air tamponade with 1 day prone positioning produce favorable anatomic and functional outcomes.

OBJECTIVETo observe the effects of electroacupuncture (EA) on the apoptosis of brain tissue cells and the expression of Caspase-3 in the rats with cerebral-cardiac syndrome (CCS).

METHODSA total of 70 healthy SD rats were selected. Ten was randomly recruited as the sham-operation group, and the rest were used for CCS model preparation. Thirty successfully modeled rats were divided into the model group, the EA group, and the non-EA group, 10 in each group. The model was prepared using injecting collagenase + heparin into the caudate nucleus. Equal volume of 0.9% sodium chloride injection was injected to rats' caudate nucleus in the sham-operation group. EA was started on the 1st day of modeling. Shuigou (GV26), Fengfu (GV16), Neiguan (PC6), and Xinshu (BL15) were needled in the EA group. Four points in the hips were needled in the non-EA group. The EA needling lasted for 20 min each time, once daily, for 3 successive times. No EA was administered to the sham-operation group or the model group. The apoptosis of brain tissue around the hematoma and the expression of Caspase-3 were detected using TUNEL and immunochemical assay.

RESULTSTUNEL cells could be occasionally seen with fewer Caspase-3 expression in the sham-operation group. More TUNEL positive cells appeared in the tissue around the hematoma of the model group with a large amount of Caspase-3 expression. The TUNEL positive cells and Caspase-3 expression were obviously less in the EA group than in the model group and the non-EA group (P < 0.01).

CONCLUSIONSEA could inhibit the apoptosis of brain tissue cells in CCS rats. Its mechanisms might be associated with down-regulating the Caspase-3 expression of the brain tissue around the hematoma.

OBJECTIVEGlutamine has protective effects against renal injuries. This study was designed to explore the possible mechanism underlying the protections by examining the effects of glutamine on extracellular signal regulated kinase (ERK) and p38MAPK expression in the kidney in rats with endotoxemia.

METHODSOne hundred and twenty-one 18-day-old Wistar rats were randomly injected with LPS (4 mg/kg; n=55), LPS (4 mg/kg)+glutamine (1 mL/kg) (n=55), or normal saline (control group; n=11). The two LPS groups were subdivided into five groups sacrificed at 2, 4, 6, 24 and 72 hrs after administration (n=11 each). ERK-2 and p38MAPK mRNA and protein expression in the kidney were measured by RT-PCR and immunohistochemistry.

RESULTSCompared to the control group, the mRNA and protein expression of both ERK-2 and p38MAPK in the LPS group significantly increased 2, 4, 6, 24 and 72 hrs after administration (P<0.01), and reached a peak at 6 hrs (P<0.01). In the LPS+glutamine group, the trend of ERK-2 and p38MAPK expression was similar to the LPS group but their expression levels were significantly lower than those in the LPS group at all time points (P<0.05 or 0.01).

CONCLUSIONSBoth ERK-2 and p38MAPK expression increased in young rats with LPS-induced endotoxemia. Glutamine alleviates renal injuries possibly by decreasing the expression of both.

OBJECTIVETo assess the clinical efficacy and safety of three different methods of anesthesia during transrectal ultrasound guided prostate biopsy.

METHODSFrom July 2006 to October 2008, a total of 120 patients who underwent 12-core prostate biopsy with transrectal ultrasound guidance because of elevated prostate specific antigen and/or abnormal digital rectal examination were randomized into 4 groups, each group consisted of 30 patients. Group A received no anesthesia. Group B received an injection of 10 ml dose of 1% lidocaine (5 ml per side) into the region of the prostatic vascular pedicle at the prostate base just lateral to the junction between the seminal vesicle and prostate on each side for periprostatic nerve block (PNB). Group C received intrarectal lidocaine gel plus PNB. Group D received an injection of 4 ml dose of 1% lidocaine (2 ml per side) into 2 sites of the right and left sides of prostate for intraprostatic anesthesia plus PNB. The efficiency of anesthesia was assessed by a visual analog pain scale (VAS). All patients were followed up within one week for the evaluation of complications.

RESULTSThe combination of intraprostatic anesthesia and PNB provided significantly better pain control than PNB alone. According to VAS, only group C (2.7 +/- 1.1) scores showed significantly better pain control than other groups (P < 0.05) during probe insertion, and only group D (3.9 +/- 1.3) scores showed significantly better pain control than other groups (P < 0.05) during biopsy. No difference was observed regarding the complications rate in the 4 groups (P > 0.05).

CONCLUSIONSCombination of intraprostatic anesthesia and PNB is effective and safe technique during transrectal ultrasound guided prostate biopsy without increasing the incidence of complications. PNB or PNB plus intrarectal lidocaine gel couldn't significantly reduce pain during biopsy.
