BACKGROUND:As for patients with one-side backleg pain who were candidates for surgery treatment of lumbar intervertebral disc herniation, the common treatment includes lumbar vertebral plate opening and decompression, and laminectomy in combination with compression and bilateral pedicle screw fixation. However, these therapeutic approaches are not satisfactory. OBJECTIVE:To explore the feasibility and efficiency of single-side lumbar interbody fusion and unilateral pedicle screw fixation for treatment of lumbar intervertebral disc herniation patients with one-side backleg pain. METHODS:Forty patients with single-side lumbar disc herniation, suffering from unilateral backleg pain, were recruited from Shihezi People’s Hospital, China and were treated with single-side lumbar interbody fusion and unilateral pedicle screw internal fixation. The neurological function of patients was assayed using Japanese Orthopaedic Association score system before and after treatment, the improvement rate and excellent/good rate were calculated. Suk criterion was used to determine fusion status. RESULTS AND CONCLUSION:The mean fol ow-up period for 40 patients was ranging from 6 months to 60 months. Al incisions healed wel , with no infection. The Japanese Orthopaedic Association score after 6 months of treatment was significantly higher than that before treatment (P<0.05), with the excellent and good rate up to 88%. According to Suk criterion, 38 patients achieved bone graft fusion or possible fusion, with interbody fusion rate 95%, as revealed by radiographic and CT evidence. The remaining two patients were detected fusion at 9 months after treatment. Our findings indicate that, single-cage lumbar interbody fusion combined with single-side pedicle screw fixation is the feasible surgical technique and provides satisfactory effects in treating single-side lumbar disc herniation.

To introduce the international registration condition of acupuncture clinical research. With the examples of World Health Organization International Clinical Trials Registry Platform and the U. S. National Institutes of Health Clinical Registration Platform, the registration method and current condition of acupuncture clinical trials in international clinical trials registration platform were analyzed. The results indicate that the number of acupuncture clinical trials registration is gradually increased and the registration number from China is on the rise as well. But most domestic acupuncture clinical researches haven't been registered arid the researchers' valuing degree for clinical trials registration and methodology research needs to be improved.

Objective To introduce the clinical significance and pathophysiologic aspects of the circulatory and cardiac complications in terminal stage cirrhosis.Methods Recently relevant literatures were reviewed and summarized.Results Haemodynamic changes in cirrhosis arose on the basis of combined humoral and nervous dysregulation,with abnormalities in cardiovascular regulation,volume distribution and cardiac performance.Conclusion Comprehending the mechanisms of cardiovascular complications will contribute a lot for the treatment of terminal stage cirrhosis.

Atomoxetine is a noradrenaline transmitter reuptake inhibitor which can selectively inhibit presynaptic noradrenaline transport protein,strengthen noradrenaline's resupination effect,and increases noradrenaline's activity released by synaptic cleft to improve the symptoms of the attention deficit hyperactivity disorder(ADHD)patients.ADHD patients often accompany with other psychological diseases like oppositional defiant disorder,anxiety disorder,which may hinder the diagnosis of ADHD.There is still no accepted effective medicine nowadays.Currently,research on the treatment of the ADHD is more and more popular.Good therapeutic effect of atomoxetine to treat ADHD has been found in resent studies.This article summarized the current management of using atomoxetine to treat ADHD.

Objective To evaluate positive p-mTOR expression and its significance in gastric cancer.Methods Original studies published for the correlation between p-mTOR and clinicopathological parameters as well as prognostic significance were enrolled from Cohrane Library,Pubmed,EMbase database and CBM,CNKI.Analyses were performed by software REVMAN 5.0.Age,gender,TNM stage,lymph node metastasis,type were analyzed using pooled odds ratio (OR) with 95％ confidence interval (CI),and OS were analyzed using pooled hazard ratio (HR) with 95％ CI.Results Seven studies including 2 477 gastric cancer patients were enrolled in the meta analysis.p-mTOR expression was positive in 1 089 of the cases.p-mTOR positive expression was correlated with age,OR =0.74,95％ CI:0.62-0.89,dcpth of invasion OR =0.76,95％ CI:0.60-0.97,lymph node metastasis,OR =1.95,95％ CI:1.59-2.39,TNM stage,OR =0.57,95％ CI:0.38-0.84,type,OR =0.64,95％ CI:0.50-0.83,and OS,HR =1.86,95％ CI:1.60-2.16.Gastric cancer patients with p-mTOR positive expression tend to be younger,had a higher risk of lymphatic invasion,later TNM stage and poor prognosis.Its positive expression had no relation with the gender.Conclusion p-mTOR positive expression is a significant predictor for advanced TNM stage,more lymph node metastasis,intestinal type and poorer OS.

Objective To analyze the clinical features and image manifestations of hepatic inflammatory myofibro-blastie tumor( HIMT), and to investigate the optimal management of this disease. Methods From January 2000 to January 2007, clinical data with HIMT verified by pathology were retrospectively analyzed. Results Eight patients 5 men, 3 women were included in the analysis. The mean age was 41.3 years. All eases did not have a history of previous hepatitis and liver cirrhosis, and 6 with no typical clinical symptoms. Hepatic functions, serum levels of AFP, CEA, CA199 in these patients were all within the normal ranges. Preoperative imaging by ultrasonography and computed tomography(CT) were not indicative of HIMT. Morphologic features by CT scan were summarized: at nonenhanced CT, the masses appeared as low density lesions. At contrast enhanced CT, the masses exhibited mod-erate intensification in the solitary areas, and the intensification peak appeared during the period of artery. During the period of portal vein and delayed scan, the masses showed low to moderate intensification in the solitary areas, in which the degree of intensification was a little lower than that in peripheral liver parenchyma. Gross specimens showed single solid masses, 3～12 cm, without classic envelope. All the patients underwent surgery whereas no incidence of perioperative death. Diagnosis of HIMT was confirmed by pathology of surgical specimens. Condusion Although typical presentation and the diagnostic workup are still lacking for HIMT, CT is helpful in diagnosing HIMT as well as combined with clinical findings. Surgical management would be likely the optimal treatment of this disease.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.
