Objective To investigate the distribution modes of NOS nerves and interstitial cells of Cajal (ICCs) in myenteric plexus of human fetal intestine. Methods Small intestine samples from 12 fetuses were collected for the preparation of whole mount preparations and cryo sections examined by immunocytochemistry for c kit receptor tyrosine kinase and histochemistry for NADPH diaphorase. Results ICCs associated with the myenteric plexus in the fetal small intestine were observed in the shape of spindle or ovoid with two to three slender processes forming an independent and complete cellular network. While NOS positive nerves, which constitute the main neuronal component of ganglia, connecting strands, and nerve fibers, were found within the circular muscle layer and myenteric plexus of the small intestine and the latter was especially rich of this kind of nerves. Most of these positive neurons were Dogiel I type neurons and they often gathered in cluster in the ganglia. Each ganglion contained several to dozens of NOS positive neurons. Although no colocalization of ICCs and NOS positive nerves was found by double staining of whole mount preparations and cryo sections, they were closely distributed. Conclusion Our results indicate that NO released by myenteric plexus, an inhibitory neurotransmitter, may possess the function of regulating ICCs and smooth muscle in late stage of the fetus.

Objective To investigate the clinical efficacy,operative essentials and indications of hybrid spinal fusion surgery for cervical spondylotic myelopathy.Methods From August 2008 to December 2011,thirty-eight patients with cervical spondylotic myelopathy underwent hybrid spinal fusion surgery in our hospital.There were 27 males and 11 females,aged from 33 to 70 years (average,51 years).A total of 86 segments were treated (fusion 48 vs.non-fusion 38).Twenty-eight patients underwent a two-level surgery,and ten patients received a three-level surgery.The Japanese Orthopaedic Association (JOA) score and Visual analogue scale (VAS) were used to evaluate pre-and post-operative neurological function and pain,respectively.The pre-and post-operative range of motion of the cervical spine was measured according to Xrays.Moreover,the surgical complications were recorded and analyzed.Results Thirty-seven patients were followed up for 15 to 55 months (average,29.1 months).The improvement of neurological function was obtained in 36 patients.The JOA score was improved from preoperative 10.5±1.57 to 14.3±1.97 at final follow-up,with an improvement rate of 58.46％,and the results were excellent in 16 cases,fair in 20 cases and poor in 1 case.The VAS was improved from preoperative 7.3±1.04 to 3.2±1.41 at final follow-up.The Cobb angle changed from preoperative 25°±3.21°to 20°±2.56°at final follow-up.After operation,the neurological function was not restored in 1 case; hoarseness and bucking occurred in 2 cases; sore throat occurred in 22 cases; anterior displacement of prosthesis (PCM) occurred in 3 cases.Other patients had no complications,such as displacement,loosening and heterotopic ossification.Conclusion In hybrid spinal fusion surgery,the lesions segments are decompressed fully,the severely degenerative segments are fused,and the motion of the non-fusion segments is reserved.As a result,not only the stability of the cervical spine is achieved,but also an obvious improvement of symptoms and a satisfactory short-term efficacy can be obtained.Therefore,this method is an alternative procedure for cervical spondylosis myelopathy.

Acute increase of serum alanine aminotransferase(ALT) and aspartate aminotransferase(AST) was also reported in association with significant decrease of albumin .The patients were treated with comprehensive measures targeting shock ,infection ,heart failure ,respiratory failure ,and relevant symptoms .The overall mortality was 66 .7% (20/30) .The mortality was significantly higher in Child‐Pugh C cirrhotic patients than Child‐Pugh A or B patients .Conclusions The ischemic hepatitis in association with liver cirrhosis is mainly induced by hypovolemic shock ,severe sepsis ,heart failure ,and respiratory failure .Typical laboratory findings are sharp elevation of serum ALT and normalization after treatment . Liver cirrhosis complicated with ischemic hepatitis features high mortality ,particularly in Child‐Pugh C cirrhosis .

Retinal pigment epithelium ( RPE ) is a vital tissue for the maintenance of photoreceptor function and environment of outer retina, also the predominant cell type of proliferative vitreoretinopathy ( PVR ) . lt is also affected by many diseases of the retina and choroid, including diabetic retinopathy ( DR) , age-related macular degeneration ( AMD ) and retinal pigmentosa ( RP ) . Although of neural origin, the RPE is capable of local repair, and cells may migrate and take on altered characteristics. These findings indicate that RPE-based therapy is a promising option for congenital or degenerate disease of the retina.

A systematic review was undertaken, including studies that evaluated the incidence of the blood system adverse events of Tripterygium wilfordii (TWP). Medline, Embase and the Cochrane library were searched for relevant studies, including RCT, cohort studies and case series, of patients treated with TWP published in English and Chinese from inception up until May 25th, 2013 with the keywords including "Tripterygium wilfordii", "toxicity", "reproductive", "side effect", "adverse", "safety" and "tolerability". Relevant information was extracted and the incidence of the blood system adverse events was pooled with MetaAnalyst software. Besides, subgroup and sensitivity analyses were performed based on age, mode of medicine, observation time and disease system. According to inclusion and exclusion criteria, a total of 49 articles were included in the meta-analysis, they were split into 54 researches incorporated in the analysis. There is a large degree of heterogeneity among the studies, so data was analyzed using random-effects model and the summary estimates of incidence of the blood system adverse events was 6.1%. The weighted combined incidence of three major blood system adverse events were white-blood cells decreasing 5.6% (95% CI, 4.3% - 7.3%), hemoglobin decreasing 1.7% (95% CI, 0.5% - 5.0%) and platelet decreasing 1.8% (95% CI, 1.0% - 3.1%), respectively . Sensitivity analyses based on 45 studies with high quality showed the combined value was close to the summary estimate of total 54 studies. The current evidence indicates that the incidence of the blood system adverse events induced by TWP was high; attentions should be paid on to the prevention and treatment of the blood system adverse events.

BACKGROUND: Directly percutaneous injection of protein-denaturant hydrochloric acid (PDHA) into tumors can lead to fast killing of tumor, sustained drug release and prevention of in situ recurrence of tumor. However, whether implants can be used combined with denaturant still remains unknown. OBJECTIVE: To investigate the compatibility of fluorouracil implants and PDHA (6 mol/L). DESIGN, TIME AND SETTING: Observational study was performed in the Hefei Industry University between October 2006 and March 2007. MATERIALS: A total of 78 Wistar rats, weighing (200i20) g, half males and half females, were used for testing drug release in vivo. Drugs fluorouracil implants (H20030345; columniform particle, diameter 0.8 mm, length 4 mm; specifications: Fluorouracil 2 mg/particle; batch number: 20060922; meeting the National Drug Quality Standards [WS1-(X-103)-2005Z]) were provided by Wuhu Zhongren Pharmaceutical Company,Ltd. Hydrochloric acid (37%) was analytical reagent. METHODS: 96 tubes of the implants and PDHA were kept at (37.0± 0.5) ℃. Each time, six samples were collected at 1, 8, 16, 24, 96, 120, 168, 240, 360, 432, 480, 528, 600, 720, and 960 hours after incubation. Appearance of the implants was observed by microscope. Stability of fluorouracil in PDHA was determined by HPLC and ultraviolet absorb method. Based on the entering quantity and residual quantity of fluorouracil, the release rates were calculated. MAIN OUTCOME MEASURES: The approximate solubility, stability and morphological change of fluorouracil in denaturant and the corresponding drug release character in both denaturant and rats in vivo. RESULTS: At (37.0±0,5) ℃, the fluorouracil was stable for 960 hours in PDHA, the saturated concentration of fluorouracil was (22.72±0.04) g/L. The appearance of implants was intact. The surface was porous. Compared with the speed of releasing drug in rats, the speed of releasing drug was faster in the early stage of release process and slower in the later stage. The drug release was incomplete. At 1, 24, 96, 360 and 960 hours, the implants' release rates were (11.9±6.7)%, (37.9±5.3)%, (52.6±4.5)%, (75.3±3.8)%, and (85.5±2.1)%, respectively. CONCLUSION: The fluorouracil implants and hydrochloric acid (6 mol/L) are compatible and no influence is detected during the observation.
