Objective To explore preliminary clinical results of a new anatomical shape allogeneic bone posterior lumbar fusion cage. Methods Follow-up patients used the allogeneic bone posterior lumbar fusion cage and use imaging methods and clinical score (VAS, ODI) to evaluate the patients′ clinical efficacy. Results 14 patients were followed up for 6 months or more , with an average follow-up time of 9.7 months , mean preoperative VAS 6.8 ± 1.1, ODI 32.7 ± 4.5. The mean preoperative disc height was (9.7 ± 2.0) mm and the average intervertebral height of 3 days post operation was (13.2 ± 1.7) mm. All patients got bony fusion in 6 months post operation, pain and function scores improved significantly compared with the pre-operation: VAS 2.4 ± 0.8 (P =0.000), ODI 9.8 ± 2.5 (P = 0.000), the average intervertebral height was (13.1 ± 1.7) mm (P = 0.000). The average was VAS 2.1 ± 0.1 (P = 0.000), average ODI was 8.9 ± 0.9 (P = 0.000) at last follow up. Average of intervertebral height was (13.0 ± 1.8) mm, no significant difference compared to three days after surgery (P=0.831). No serious complications and deep surgical site infection was observed. All implants were found no fragmentation, shift, cutting boards, and obviously sinking. Conclusion The anatomical shape allogeneic bone posterior lumbar fusion device is suitable for posterior lumbar interbody fusion , advantages of high fusion rate , satisfactory clinical results in the initial clinical trials , but its long-term efficacy requires further observation.

Objective: To determine the changes of serum Tau protein, glial fibrillary acidic protein (GFAP), tumor necrosis factor alpha (TNF-α), and malonaldehyde (MDA) in rats after blast-related traumatic brain injury (BTBI) and to provide relative information for further studies on BTBI mechanism and seek specific biomarkers for BTBI.
Methods: Ninety male Sprague-Dawley rats were randomly assigned into three groups: control group, moderate blast injury group, and severe blast injury group (n=30 for each). Rats in the moderate and severe blast injury groups were respectively exposed to corresponding levels of BTBI. After explosion, serum levels of Tau, GFAP, TNF-α, and MDA in each group were determined by Elisa assay at different time points after injury (8 h, 24 h, 3 d, and 6 d). The extent of brain damage was detected by Nissl staining and TUNEL assay.
Results: Serum levels of Tau and GFAP rapidly increased and reached the peak at 24 h after either moderate or severe blast injury. All the values were significantly higher than control group at all time points (P<0.05). Serum TNF-α level of both injury groups peaked at 8 h after BTBI and stayed significantly higher than control group at all time points (P<0.05). Serum MDA of two injury groups began to significantly increase at 3 d and the level stayed significantly higher than control group until 6 d (P<0.05). Moreover, unlike the other biomarkers, serum MDA of severe blast injury group was significantly higher than moderate blast injury group at 6 d (P<0.05).
Conclusion: The changes of serum Tau, GFAP, and TNF-αshowed a good sensitivity at the acute phase after BTBI (within 24 h). However, their specificity and correlation with the extent of injury were limited in this experiment. Moreover, although the change of serum MDA showed a poor sensitivity and specificity to the diagnosis of BTBI during the first few days, it can reflect the injury degree at 6 d after injury. Therefore, further studies are needed to improve the methods of detecting more serum markers and investigate the significance of multiple markers in diagnosing BTBI.

Dimethyl sulfide (DMS) has been historically recognized as a metabolite of the marine microorganism or a disgusting component for the smell of halitosis patients. In our recent study, DMS has been identified as a cytoprotectant that protects against oxidative-stress induced cell death and aging. We found that at near- physiological concentrations, DMS reduced reactive oxygen species (ROS) in cultured PC12 cells and alleviated oxidative stress. The radical-scavenging capacity of DMS at near-physiological concentration was equivalent to endogenous methionine(Met)-centered antioxidant defense. Methionine sulfoxidereductase A (MsrA), the key antioxidant enzyme in Met-centered defense, bound to DMS and promoted its antioxidant capacity via facilitating the reaction of DMS with ROS through a sulfonium intermediate at residues Cys72, Tyr103, Glu115, followed by the release of dimethyl sulfoxide (DMSO). MTT assay and trypan blue test indicated that supplement of DMS exhibited cytopro?tection against 6-hydroxydopamine and MPP + induced cell apoptosis. Furthermore, MsrA knockdown abolished the cytoprotective effect of DMS at near- physiological concentrations. The present study reveals new insight into the potential therapeutic value of DMS in Parkinson disease.

Objective To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF)and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF.Methods One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF(the main stem of portal veins are visible).However,there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible).After the embolization,all of the 26 patients who have severe HAPVF stopped bleeding.Among them,the main stem of hepatic arteries are occluded in 2 patients. Conclusion The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients,and it can be diagnosed through hepatic artery DSA.Orifice embolization is the most effective method for such kind of hemorrhage.

OBJECTIVETo investigate the correlation of vasectomy with the risk of prostate cancer in Chinese men.
METHODSWe systematically searched the databases CNKI, VIP, Wanfang, PubMed, Embase, and Cochrane Library for the literature relating the relationship between vasectomy and the risk of prostate cancer in Chinese males up to December 2014. According to the inclusion and exclusion criteria, two investigators independently selected the eligible publications, evaluated their quality, and extracted relevant information, followed by a meta-analysis with the software STATA 12.0.
RESULTSNine studies were included in the analysis involving 1 202 cases of prostate cancer and 4,496 controls. Random-effect model analysis revealed no statistically significant correlation between vasectomy and the risk of prostate cancer (OR = 1.05; 95% CI 0.62-1.79), with an obvious heterogeneity (P < 0.001, I2 = 85.7%). No significant publication bias was found among the included studies (Egger, P = 0.824; Begg, P = 0.348).
CONCLUSIONThe results of our meta-analysis do not support the association of vasectomy with the increased risk of prostate cancer in Chinese population.
