OBJECTIVETo compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation.

METHODSFrom January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups.

RESULTSIn treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects.

CONCLUSIONT-shaped locking internal fixation with postoperative functional exercise for the treatment of dorsal Barton's fracture fits for biomechanics demands,and has advantages of stable fixation,rapid recovery, less complications and good functional recovery, it has better clinical effects.

OBJECTIVETo provide basis for strengthening safety of acupoint-injection and increasing clinical therapeutic effect.

METHODSAnalyze and study on the relative articles from the databank of whole articles of Chinese periodicals of CNKI by information retrieval with computer, with acupoint-injection, nerve injury as key words.

RESULTSMost of clinical reports focus on acupoint-injection for treatment of nervous injury induced by trauma and birth injury. The studies indicate that the injuries of the peripheral nerves induced by acupoint-injection can be divided into 3 grades and the injury mechanisms can be divided into 3 classifications. The injuring causes include improper posture of the patients, improper angle and depth of injection and improper medicine selection.

CONCLUSIONAcupoint-injection can be applied more widely as soon as the accomplishment of the standardization of operation.

17 strains of bacterium that produced a large amount of ?-PGA when it was grown aerobically in a culture medium containing ammonium salt and sugar as sources of nitrogen and carbon respectively,were isolated from bean products.With the following identifications of colony morphology,physiological and biochemistry experiments,and genetics,the strain PGA-O-7 was classified as a Bacillus subtilis.The PGA production 2.8 (mg/mL) was obtained when it was grown in a medium containing 3% ammonium sulfate and 4% glucose at 30℃ for 72h with sharking.

A high productive poly ?-glutamic acid(?-PGA) strain PGA-N in a culture medium containing no L-glutamine was isolated from fermentation products.With the following identifications of colony mor-phology,physiological and biochemistry experiments,and genetics,the strain PGA-N was classified as a Bacillus licheniformis.According to the product environment,the base culture medium having no L-glutamine was simulated.In order to enhance the production of the strain PGA-N,the fermentation condi-tions,such as carbon source,nitrogen source,were optimized and the ?-glutamic acid production reached 5.16 g/L after getting the optimum formulation of this culture medium.PGA-N was mutagenized with com-bination of NTG and UV.A mutant PGA-N-C10 was screened which PGA production was increased from 5.16 g/L to 8.82 g/L.The study also investigated the effects of agitation speed on the cell biomass,?-PGA production and the ?-PGA molecular weight.The ?-PGA yield of PGA-N-C10 was as high as 11.00 g/L when the agitation speed was 400 r/min.

Acetic acid bacteria are Gram-negative,obligate aerobic bacteria that have the ability to incompletely oxidize alcohols or sugars to organic acids as end products. The taxonomy of acetic acid bacteria has undergone many changes in the last 30 years. The early classification systems for these bacteria were based on morphological and biochemical characteristics. Today,the acetic acid bacteria are classified as the consensus result of a polyphasic analysis,combining phenotypic,chemotaxonomic and genotypic data. This paper reviewed the polyphasic taxonomy of acetic acid bacteria,mainly introduced the current classification of acetic acid bacteria,then discussed the application of phenotypic,chemotaxonomic and genotypic method in the taxonomy of acetic acid bacteria.

Objective: To explore the relationship between expression of tumor necrosis factor-α( TNF-α) and electrophysiological heterogeneity in isolated heart tissues and isolated rat ventricular myocytes.The arrhythmogenic mechanisms of TNF-αwere further studied.Methods:Langendorff perfused heart tissues models were used to verify the arrhythmogenic effects of TNF-α.The monophasic action potentials( MAPs) of the endocardium and epicardium from the isolated heart tissues were recorded by elec-trophysiological experiments.The isolated rat ventricular myocytes were obtained by enzymatic dissociation.K+currents(Ito,IK1)were recorded by using whole cell patch clamp technique.Results: Compared to the control group, the difference in MAPD between endocardium and epicardium dramatically increased with TNF-α( P<0.05 ) .TNF-αcould cause MAP duration ( MAPD ) prolongation, and a single dose of TNF-αdifferentially affected the MAPs of endocardium and epicardium of isolated heart tissues.Compared to the control group,the K+currents(Ito,IK1)were dose-dependently decreased with TNF-αin rat ventricular myocytes(P<0.05).However, etanercept had no effects on the MAPD in the absence of TNF-α.Conclusion:TNF-α-induced heterogeneity of MAPD between the endo-cardium and epicardium may provide the substrate for the onset of ventricular arrhythmias during acute myocardial infarction.The effect might be associated with TNF-αcontribute to re-entrant ventricular arrhythmias which resulted from decreased K+currents(Ito,IK1).

Objective To study the characteristics and clinical features of positive response during head - up tilt test (HUT) in children. Methods Forty- nine cases of syncope and aura of syncope were included in the study. All of them underwent HUT (tilt angle 60 degree,lasting 45 minutes). During the test,children' blood pressure,heart rate.electrocardiography and clinical symptoms and signs were dynamically observed. Results The common syncope aura symptoms were headache, dizziness, chest distress, difficulties in breathing, pale, perspiration, blurred vision, auditus depression and symptoms related to digestive symptoms. Among the 28 positive cases, 7 cases were of vaso - inhibitory pattern (25%), with a decrease in blood pressure and an increase in heart rate, 3 cases inhibitory pattern (11%), with a decrease in heart rate but withoilt'blood pressure changes, 4 cases mixed pattern (14 %), with decreases in heart rate and blood pressure obviously, 10 eases POTS (36%), with an increase in heart rate by 30 bpm or up to 120 bpm within 10 minutes while testing, and 4 cases orthostatic hypotension (14%), with a decrease in blood pressure within 3 minutes. Conclusion HUT can be regarded as the main tool in differential diagnosis of unexplained syncope in children.

Objective To discuss the clinical diagnostic method of postural orthostatic tachycarda syndrome(POTS) in children.Methods Thirty-six children with POTS were selected for the research.Among them 15 were boys,21 cases were girls.The age ranged from 5.9 to 16 years,average age 12.3 years.Among them 28 patients(78%) were in between 11-16 years.The age distribution,clinical courses and hemodynamic indexes were analyzed and also the incidence of clinical manifestations and investigation reports were observed.Results Among 81 patients of orthostatic regulation disturbance,36 patients were diagnosed POTS,which was 47% of total.The clinical courses ranged from 1 day to 5 years,average clinical course 10.2 months.The clinical courses of more than half of the total patients were within 6 months(56%).The common clinical features of POTS were chest tightness on standing,vertigo,fatigue,palpitation,syncope,orthostatic regulation disturbance.Ten patients were also associated with gastrointestinal symptoms like nausea,vomiting.The most common feature of POTS patients was tachycardia(HR increased by ≥30 times/min) within 10 min after head-up tilt test(HUT).Average HR increased by 38 times/min.In some patients HR increased up to ≥120 times/min.There were no significant changes in blood.In 23 cases(64%),the T waves were descended by ≥0.2 mV in 2 or more than 2 leads in ECG reading.Investigations reports showed that there were 12 cases whose urine specific gravity was increased.In 11 cases HCO_3~-decreased.Conclusions POTS is commonly seen in schooling female children.The common symptoms are vertigo,chest tightness,fatigue,palpitation.HUT is an important method for the diagnosis of POTS.
