BACKGROUND:Spinal cord ischemia-reperfusion injury is a serious secondary injury of the spinal cord. Multifactor could contribute to the mechanism of this injury, and many therapeutic measures emerge, but the therapeutic effect is not ideal.
OBJECTIVE:To investigate the protective effects and mechanism of hydrogen-rich saline on spinal cord ischemia-reperfusion injury in rabbits.
METHODS:ZIVIN method was adopted to prepare the model of spinal cord ischemia-reperfusion injury. The rabbit models were randomly divided into model group, sham operation group, and hydrogen-rich saline group.
RESULTS AND CONCLUSION:Improved Tarlov scores for the evaluation of motor function were significantly increased in hydrogen-rich saline group compared with the model group at 6, 12, 24, 72 hours after reperfusion (P<0.01). The contents of malondialdehyde were significantly lower (P<0.05), while catalase activity was significantly higher (P<0.05) in hydrogen-rich saline group than that in model group at 72 hours after reperfusion. Hematoxylin-eosin staining revealed that, spinal cord anterior-horn motor neurons maintained intact structure in sham operation group;more necrotic spinal cord anterior-horn motor neurons were found in model group, and granular-vacuolar degeneration occurred in the endochylema. In hydrogen-rich saline group, the structure of spinal cord anterior-horn motor neurons was basical y intact, only a smal amount of spinal cord anterior-horn motor neurons appeared vacuolar degeneration. TUNEL staining showed no apoptotic spinal cord anterior-horn motor neurons in sham operation group. Many inflammatory cel s and apoptotic neurons were found in model group. There were few inflammatory cel s and apoptotic neurons in hydrogen-rich saline group. Hydrogen-rich saline can prevent the apoptosis of spinal cord anterior-horn motor neurons in rabbits with spinal cord ischemia-reperfusion injury, and the underlying mechanism is associated with antioxidative effect.

OBJECTIVE: To investigate the preventive effect of Bushen Huoxue Recipe (BSHXR), a compound traditional Chinese herbal medicine, on autoimmune premature ovarian failure (POF) in mice. METHODS: Ovarian antigen was prepared with the ovarian tissue of female BALB/c mice. A mouse model of POF was established by immunization injection of the ovarian antigen of isotype female mice on multiple subcutaneous sites and two posterior soles. The POF mice were treated with BSHXR after the first and third immunization. The levels of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in peripheral blood were detected by enzyme linked immunosorbent assay. RESULTS: Lymphocyte infiltration was appeared in ovarian stroma of POF mice. The levels of FSH and LH were evaluated and the E(2) level was decreased significantly (P<0.05). BSHXR could reduce the increased levels of FSH and LH, increase the level of E(2) and the number of growing and mature follicles. The efficacy of early treatment was better than that of late treatment. CONCLUSION: BSHXR can recover ovarian function in POF mice mainly by regulating the indiscriminate hormone level, and BSHXR has preventive effect on autoimmune POF in mice.

UNLABELLEDOBJECTIVE; To evaluate the efficacy and safety of Jiangtang Xiaozhi Capsule (JTXZC) in treating type 2 diabetes mellitus (T2DM) of qi-yin deficiency phlegm-stasis inter-obstruction syndrome (QYDPSIOS), and to observe its effect on inflammatory factors and fibrinolytic factors.

METHODSBy adopting a randomization grouping, parallel control, and prospective study, 73 T2DM patients of QYDPSIOS were assigned to two groups by random digit table, the Pioglitazone Tablet group (36 cases, as the control) and the JTXZC group (37 cases). All patients maintained their basic therapies and lifestyle as previous after recruitment. Patients in the JTXZC group took JTXZC, 4 pills each time, three times per day, while those in control group took Pioglitazone Tablet, 15 mg each time, once daily. The therapeutic course for all was 8 weeks. The body weight (BW), the height, body mass index (BMI), waist circumference (WC), hip circumference, waist-to-hip ratio (WHR), and scoring of Chinese medicine (TCM) symptoms were observed. Levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h PBG), glycated hemoglobin (HbA1c), tumor necrosis factor alpha (TNF-alpha), nuclear factor kappaB (NF-kappaB), and plasminogen activator inhibitor 1 (PAL-1) were detected. The safety indices such as liver and renal functions and adverse reactions were also observed.

RESULTSCompared with before treatment, BW, BMI, HbA1c, and PBG were obviously lower after 8-week treatment than before treatment in the JTXZC group (P < 0.05). There was no statistical difference in post-treatment BW, BMI, HbA1c, or 2 h PBG between the two groups (P < 0.05). Compared with before treatment, levels of TNF-alpha and PAI-1 were lowered after 8 weeks of treatment in both groups (P < 0.01). The level of NF-kappaB was obviously lowered after 8 weeks of treatment in the control groups (P < 0.05), but it also decreased in the JTXZC group with no statistical difference. The scorings of CM symptoms were somewhat improved after treatment in the two groups (P < 0.01). Besides, better effects were obtained in the JTXZC group (P < 0.05). No severe adverse event occurred in either group during the whole therapeutic course.

CONCLUSIONSJTXZC showed similar therapeutic effect to pioglitazone. Both of them could effectively improve patients' clinical symptoms, the inflammation and fibrinolytic activities in different pathways, with no severe adverse reaction.

Objective To evaluate the clinical effect and feasibility in treating urethral stricture caused by benign prostatic hyperplasia in elder with transurethral implanted stent(Memotherm) under X-ray guided.Methods 47 patients included in this study,they ranged in age from 72 to 93 years,with an average age of 78.3 years,the symptom of dysuria ranged from 7 to 21 years.After 1% Lidocaine urethra mucous membrane anaesthesia,the processes of transurethral implanted stents at the most narrowing area of the urethra under X-ray guided were performed.Results The treating processes were successful in all cases(100%) one time,of them,the micturition in 43 cases was free and could act on one's own immediately after stent implantation.None having urethral restricture and lithiasis occured.Conclusion The clinical therapeutic effect was obvious using the memory alloy net-like stent for the treatment of urethral stricture caused by benign prostatic hyperplasia,it is worth promoting application in clinic.

Objective To construct the recombinant adenovirus of mouse Osf2/Cbfal gene and to observe its ability to infect NIH3T3 fibroblasts. Methods The Osf2/Cbfal gene fragment was cloned into the shuttle plasmid pAdTrack-CMV to form the transfer vector by the method of homogenous recombination in bacteria. Then the recombinant adenovirus was transfected into NIH3T3 cells using Lipofectine DOTAP, The target gene was detected by poly-merase chain reaction (PCR). The titer and its infection rate were determined using the green fluorescent protein (GFP) expression in the shuttle plasmid. Results Restriction endonuclease and PCR analyses confirmed that the Osf2/Cbfal gene was successfully inserted into the adenovirus vector. The titer of the recombinant adenovirus was 1.6?1012 pfu/ml. The adenovirus had a strong effect on NIH3T3 cells. Conclusion The recombinant adenovirus containing Osf2/Cbfal gene was successfully constructed by the method of homogenous recombination in bacteria.
