Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.

OBJECTIVETo analyze the causes of delayed union or nonunion of the ulna after intramedullary nailing in pediatric forearm fractures.

METHODSFrom February 2005 to February 2010,5 patients with forearm fractures who were treated with titanium elastic nailing (TEN) were identified to fulfill the criteria of having developed a delayed union or nonunion of the ulna. The causes of delayed union or nonunion were investigated according to mechanism of injury, fracture location, treatments methods and postoperative management. All patients were male and the age was 3 to 14 years old with an average of 9.4 years. All fractures were located on the mid-third part of forearm. Two cases had a re-fracture. Among them, 3 cases caused by high-energy injury and 2 cases by falling down. Open reduction were performed in 4 cases while the other one was treated with closed reduction. Four patients were immobilized in an above-elbow cast, postoperatively.

RESULTSAll patients were followed up from 7 to 19 months with an average of 11.4 months. There were 4 delayed union and 1 nonunion. Three patients healed after the removal of the nail and avoidance of weight-bearing. Two patients healed by replacing another fixation. No patients had soft-tissue irritation or nail-entry-site infections.. The clinical effect was evaluated according to Daruwalla and Price scores with 3 excellent and 2 good of the results.

CONCLUSIONSUsing titanium elastic nailing for the treatment of pediatric both-bone forearm fractures is a good method. However,strict indication selection should be followed to avoid delayed union or nonunion.

OBJECTIVETo investigate the precise locations of the blood vessels and nerves surrounding the seminal vesicles (SV) in men and provide some anatomical evidence for SV-related minimally invasive surgery.

METHODSWe observed the courses and distribution of the blood vessels and nerves surrounding SVs and obtained the data for positioning the SV neuroplexes in 20 male pelvises.

RESULTSOne branch of the neuroplexes was distributed to the SVs bilaterally with the neurovascular bundles, (2.85 ± 0.18) cm from the median sulcus of the prostate (MSP), while another branch ran through the Denonvillier fascia behind the SV, (0.81 ± 0.06) cm from the MSP. The arterial SVs (ASV) originated from the inferior vesical artery and fell into 4 types, 55% going directly to the SVs as one branch, 15% running between the SV and the ampulla of the deferent duct as another branch, 25% downward as 2 branches to the SV and between the SV and the ampulla of the deferent duct respectively, and 5% as the other ASVs. The shortest distance from the ASV through the prostatic neuroplexus to the posterior SV was (1.08 ± 0.09) cm.

CONCLUSIONIn SV resection, neuroplexus injury can be reduced with a bilateral distance of < 2.85 cm and a posterior distance of < 0.81 cm from the MSP, and so can bleeding by vascular ligation between the SV and the ampulla of the deferent duct.

Objectives To assess treatment outcomes and prognosis in infants with atrial flutter (AFL).Methods Thirty-four (34) cases of infants with AFL in Hunan Children's Hospital had been analyzed for clinical features, treatment outcomes and follow-up between March, 2009 and September, 2015. Based on ECG characteristics, the patients had been divided into simple and complex AFL groups. Based on age, they had been divided into neonates and non-neonates group. The aim of this study is to compare the clinical effects of drug treatment in different types of AFL.Resultsb With digitalis alone, the cardioversion rate was 37.5%,no signiflcant difference was observed between simple and complex AFL groups (45.8% vs 12.5%,P=0.206). Combining with other drugs, the cardioversion rate was 54.5%, which showed signiflcant difference between simple and complex AFL groups (76.9% vs 22.2%,P=0.036). The overall cardioversion rate was 70.6%, which showed signiflcant difference between simple and complex AFL groups(87.5% vs 30%,P=0.003). There was no signiflcant difference in pharmaceutical cardioversion rate between neonates and non-neonates group (85.7% vs 60.0%,P=0.216). Two cases with symptoms of heart failure used synchronized cardioversion. One patient restored to sinus rhythm, and another case was still recurrent of AFL after repeated electrical cardioversion, and eventually died of cardiogenic shock. After treatment, 9 patients were still with paroxysmal AFL and atrial tachycardia episodes, including 3 cases of simple type and 6 cases of complex type who were discharged with oral digoxin and propafenone treatment at home. 24 patients were followed up (3 months to 3 years and 4 months). 16 cases restored to sinus rhythm during hospitalization had no recurrence of AFL.Conclusions The overall treatment effects of AFL in infants were good. In simple type of AFL, most of patients did not need long-term antiarrhythmic drug therapy and the prognosis was good. The prognosis of treatment with conventional drug was poor in complex AFL group, with a higher rate of recurrence of AFL.

· AIM: To investigate the expression and the possible implication of CD40/CD40L costimulatory molecules in erythema nodosum of patients with Beh(c)et's disease.· METHODS: Sampling was done from erythema nodosum of 5 patients with Beh(c)et's disease and normal skin of 2 healthy individuals. Immunohistochemical staining was performed to examine the expression of CD4, CD8, CD19, CD68, HLA-DR,CD40 and CD40L molecules in the obtained tissues.· RESULTS: Approximately 90% of epidermic cells in erythema nodosum expressed CD40 molecule. In the dermis and subcutaneous tissue, a significantly increased number of CD4+Tcells, CD8+Tcells, CD19+cells, CD68+cells, HLA-DR+cells,CD40L+cells, and CD40+cells were observed in the erythema nodosum as compared with that in normal skin. Double staining showed that CD40L molecules were expressed on 45% of CD4+T cells. CD40 molecules were expressed on 100% CD68+ cells and 59.2% of HLA-DR+cells respectively.· CONCLUSION: A number of CD40/CD40L costimulatory molecules are upreguiated in the erythema nodosum of patients with Behcet's disease.

Background Retinal angiomatous proliferation (RAP) is a subtype of neovascular age-related macular degeneration (AMD).There are currently very few studies on RAP.Objective This study was to explore the pathogenic mechanism of RAP in apolipoprotein E-deficient (ApoE-/-) mice with dyslipidemia.Methods Twenty-four 2-month-old SPF ApoE-/-mice were randomly divided into the high fat diet group and the normal diet group,and twelve 2-month-old C57BL/6 mice received the normal diet as controls.A diet with a higher content of fat was given for 4 consecutive months in the high fat diet group,and normal diet was given in the same way in the mice of the normal diet group.The mice were sacrificed at 6 months of age.The expression of vascular endothelial growth factor (VEGF) in the retinal pigment epithelial (RPE) cells,the expression of vascular endothelial growth factor receptor-2 (VEGFR-2) in the outer plexiform layer (OPL),microvascular density (MVD) and microvascular area (MVA) in the OPL were examined by immunohistochemistry and semi-quantitatively by histopathology with the Mias 2000 Imaging Analyzer System.The expression of VEGF protein in the retina was examined by Western blot.Results The MVD in the retinal OPL were (20.67±3.20) and (19.50± 1.87),respectively,in the ApoE-/-mice of the high fat diet group and the normal diet group,which were significantly higher than that (12.50±1.87) of the C57BL/6 normal diet group (all at P＜0.01).MVA in the retinal OPL were (626.49± 120.99) μm2 and (514.06±88.83) μm2 in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with the (336.52±84.96) μm2 of the C57BL/6 normal diet group (P＜0.01).The staining area of VEGF in RPE cells was (21 048±1849) μm2 in the ApoE-/-mice of the high fat diet group,showing a significant increase in comparison with the (17 116±2023) μm2 of the C57BL/6 normal diet group.However,no significant difference was found in the staining area of VEGF between the ApoE-/-mice with normal diet group and the C57BL/6 normal diet group ([17 854±2967] μm2 vs.[17 116±2023] μm2) (P＞0.05).Significant elevation was also seen in the staining area of VEGFR-2 in the retinal OPL of the ApoE-/-mice of the high fat diet group (12 193±3806)μm2 and the ApoE-/-mice of the normal diet group (11 969± 3616)xm2 compared with C57BL/6 mice of the normal diet group (5387±2225)μm2(all at P＜0.01).The relative expression values (VEGF/β-actin) of VEGF in the retinas were (1.51 ±0.32) and (1.17±0.39) in the ApoE-/-mice of the high fat diet group and the normal diet group,respectively,showing a significant increase in comparison with (0.28±0.14) of the C57BL/6 normal diet group (P＜0.01).Conclusions The expression of VEGF and VEGFR-2 in the retinas increases in the ApoE-/-mouse,which leads to the enlargement of MVD and MVA in the retinal OPL and subsequent RAP occurrence.

Objective: To observe the clinical efficacy of acupuncture plus navel acupuncture for patients with urinary retention after radical hysterectomy for cervical cancer. Methods: A total of 64 patients with urinary retention after radical hysterectomy for cervical cancer was divided into a navel acupuncture group (22 cases), an acupuncture group (18 cases) and an acupuncture plus navel acupuncture group (24 cases). All three groups received bladder function training and neuromuscular electrical stimulation. In addition, navel points were combined in the navel acupuncture group. Electroacupuncture was conducted to Qihai (CV 6), Zhongji (CV 3), Dahe (KI 12), Shuidao (ST 28), Ciliao (BL 32) and Huiyang (BL 35) in the acupuncture group. The acupuncture plus navel acupuncture group received both treatments. The catheter was removed after 3 d of treatment. Spontaneous urination, residual urine volume, urinary catheter dependence and recurrence after 3 d, 6 d and 9 d of treatment in each group were observed, respectively. Results: In the acupuncture plus navel acupuncture group, the markedly effective rates after 3 d, 6 d and 9 d of treatment were significantly higher than those in the navel acupuncture group and the acupuncture group; the urinary catheter dependence was lower than that of the other two groups, and the differences were statistically significant (P<0.05, P<0.01); the spontaneous urination time was shorter than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (P<0.05, P<0.01); the residual urine volume was significantly less than that of the navel acupuncture group and the acupuncture group, and the differences were statistically significant (both P<0.01). After the catheter was removed, recurrence was observed from the next day after spontaneous urination was resumed. There were 2 cases of recurrence in the navel acupuncture group, 2 cases in the acupuncture group and 1 case in the acupuncture plus navel acupuncture group. The recurrence rate of the acupuncture plus navel acupuncture group was significantly lower than that of the navel acupuncture group and the acupuncture group (both P<0.01). Conclusion: Acupuncture plus navel acupuncture has satisfactory efficacy for urinary retention after radical hysterectomy for cervical cancer. It can significantly shorten the urinary retention time, reduce the patient's dependence on urinary catheter, and reduce the residual urine volume.

OBJECTIVETo investigate the effect of losartan on prostatic hyperplasia in spontaneous hypertension rats (SHRs) and its pathophysiological mechanism.

METHODSWe randomly divided 36 male SHRs into three groups of equal number to be treated intragastrically with high-dose losartan (30 mg per kg per d), low-dose losartan (15 mg per kg per d) and distilled water (control group). After 6 weeks of intervention, we measured the body weight and tail artery blood pressure of the rats and compared them with the baseline data. We collected blood from the heart for determination of the levels of serum angiotensin II (Ang II), insulin-like growth factor-1 (IGF-1) and interleukin-6 (IL-6) by enzyme-linked immunosorbent assay (ELISA), and harvested their prostates for measurement of their weight, observation of the tissue ultrastructures under the electron microscope and detection of the expression of endothelial nitric oxide synthase (eNOS) in the prostate tissue by immunohistochemistry.

RESULTSCompared with the control group, the low- and high-dose losartan groups showed significant decreases in systolic blood pressure ([203.75 +/- 10.28] vs [184.54 +/- 16.90] mmHg, P = 0.013; [203.75 +/- 10.28] vs [166.88 +/- 14.74] mmHg, P = 0.001) and diastolic blood pressure ([151.58 +/- 9.96] vs [136.71 +/- 14.28] mmHg, P = 0.022; [151.58 +/- 9.96] vs [122.71 +/- 11.56] mmHg, P < 0.001) of the lower tail artery after treatment, as well as in the prostate weight ([0.73 +/- 0.08] vs [0.64 +/- 0.10] mg, P = 0.011; [0.73 +/- 0.08 ] vs [0.50 +/- 0.17] mg, P < 0.001). Electron microscopy revealed edema of the basal and columnar epithelial cells, concentrated and marginated heterochromatin and widened nuclear gap of interstitial fibroblast nuclei, and reduced mitochondria and endoplasmic reticula in the low-dose losartan group, and even more obvious in the high-dose group. The level of serum Ang II was remarkably higher in the low- and high-dose losartan groups than in the control ([61.32 +/- 2.49] vs [54.85 +/- 7.20] pg/ml, P = 0.021; [65.49 +/- 6.78] vs [54.85 +/- 7.20] pg/ml, P < 0.001]) , that of serum IGF-1 was lower in high-dose losartan than in the control group ([1.50 +/- 0.11] vs [1.60 +/- 0.10] ng/ml, P = 0.03), but the serum IL-6 levels exhibited no significant differences among the three groups. The expression of eNOS in the prostate tissue was significantly higher in the losartan groups than in the controls (P = 0.022), even higher in the high-dose than in the low-dose group.

CONCLUSIONLosartan can suppress the progression of prostate hyperplasia in spontaneous hypertension rats by inhibiting RAS, IGF-1 and angiogenesis.
