Nerve injury including peripheral nerve injury and central nerve injury has been a global problem. With the development of technology, many innovative approaches for nerve repair have been tested and some of the results are meaningful. It becomes a hot point that repair nerve injured by biological scaffold (nerve conduit). This article reviewed and analyzed several kinds of biological scaffold materials and microenvironment with better effect in recent years. Some new ideas were raised from the three aspects: appropriate materials, microstructure, and bionic microenvironment. It is better to combine multiple measures and achieve the best effect. In addition, nerve scaffold have a bright future in repair of central nervous system.

OBJECTIVETo evaluate the effects on health-related quality of life after short-segment pedicle fixation of thoracolumbar fractures without neurologic injury.

METHODSA total of 55 patients suffered from thoracolumbar fractures without neurological deficit from January 2007 to October 2010 were included in this retrospective study. Of the 55 patients, 35 were male and 20 were female. The mean age was (44.0±10.5) years old (ranged, 7 to 75). Preoperatively, the main clinical symptoms in patients were thoracolumbar pain without neurologic injury and the imaging findings mainly showed that the injured vertebra became wedging or flat with the loss of height. Three questionnaires (ODI, EQ-5D and SF-36) were applied to follow-up in this study.

RESULTSAll operations were successful and incisions got primary healing. The function of thoracolumbar spine fully or basiclly restored and postoperative imagings showed fractures healed without loose screws, broken screws or broken rods. The completion rates of all the queasionnaires were 100% while the mean follow-up period was 4.2 years (ranged, 3 to 6). The ODI scores were 25.8±18.7, which were statistically higher than those of the general population in our country (P<0.05). The EQ-5D index scores were 0.70, which were statistically lower than those of the normal Chinese population (P<0.05). Compared with the normal scores in our country, the scores of 8 items in the SF-36 questionnaire were obviously lower with significant difference (P<0.05).

CONCLUSIONCompared with the normal Chinese population, it should be paid more attention to that the health-related quality of life in patients after short-segment pedicle fixation of thoracolumbar fractures without neurologic injury because of lower scores.

Spinal cord injury is a serious disabling disease caused by a series of internal and external factors in the field of orthopaedics and neuroscience, which is a big problem for doctors all over the world. Lithium has been used to treat dipolar disorder for over 100 years. It has been reported that lithium is benefit for brain neuron. The treatment effect for spinal cord injury gets more and more attention. Researches indicate that lithium is benefit for spinal cord injury by protecting neuron,reducing after-injury inflammation increasing the produce and release of neurotrophins, stimulating neurogenesis, enhancing autophagy and inhibiting apoptosis. This article summaries advances in mechanism of treatment for spinal cord injury with lithium by reviewing and analyzing researches. Therapy combined with lithium has a good application prospect.

Objective To assess excessive daytime sleepiness (EDS) in patients with Parkinson's disease (PD) using the Epworth Sleepiness Scale (ESS) and to examine the main cause of EDS. Methods 96 consecutive PD patients and 98 age-matched healthy controls participated in the study. The severity of the disease was evaluated by Hoehn and Yahr stage (H&Y) and Unified Parkinson's disease Rating Scale-Ⅲ (UPDRS-Ⅲ), and information of anti-PD medications was collected. The correlations among EDS and age, severity of PD, PQSI score, duration of illness and medications were analyzed. Results The mean ESS score was 6.05 (S.D.3.83) in PD patients and 4.24 (S.D.3.21) in controls (P

?Corneal collagen cross-linking ( CXL ) could increase the mechanical strength, biological stability and halt ectasia progression due to covalent bond formed by photochemical reaction between ultraviolet - A and emulsion of riboflavin between collagen fibers in corneal stroma. Corneal melting is an autoimmune related noninfectious corneal ulcer. The mechanism of corneal melting, major treatment, the basic fundamental of ultraviolet- A riboflavin induced CXL and the clinical researches status and experiment in CXL were summarized in the study.

Objective To evaluate the effect of smecta on acute gastroenteritis induced by the radiotherapy in human cervical cancer.Methods seventy-eight patients under radiotherapy received smecta combined with general medicine to control gastroenteritis. All patients were divided into 2 groups:group A: 40 patients were treated with smecta and general medicine.group B:38 patients were only routinely treated. The routine medicine included prednisone, vitamin B 2 and ciprofloxacin.Results The effective rate for acute gastroenteritis in A group was significant higher than in B group ( P

Objective:To understand the mental health state of severe acute respiratory (SARS) for children from medical workers' family and to provide information on clinical psychotherapy and behavior modification during heavy spreading of infectious diseases.Methods:Each school took out two classes from grade four to six, which was from seven different sections of Xi'an, 2000 pupils were chosen randomly to complete.The observatory group (OG) and standard group (SG) include 286 and 615 primary school children whose mother is medical worker and non-medical worker, respectively. Self-made questionnaire was employed for this survey. Results:OG is significantly higher than SG on neurasthenia, fear ,depression and lower on forcer-anxiety,passiveness (P

Objective To study the sleeping quality and correlative factors of key senior middle school students of Beijing. Methods With pittsburg sleeping quality index (PSQI) scale, 344 key senior middle school students participated and completed the questionnaire. Results Percentage of sleep disorder accounted for 24.4% in the senior middle school students;Sleeping time was shorter than 7 hours in total of 61% students. Compared with key class students, sleeping time was shorter(P
