Alzheimer's disease and nerve growth factor gene therapy / 中南大学学报(医学版)

Gene therapy plays an important role in Alzheimer's disease (AD). In recent years, the research on gene delivery vector has gradually transferred from adenovirus vector, adeno-associated virus vector and lentivirus vector to liposomes and nanomaterial carrier systems. Graphene, the newest member of nanomaterial carrier system, has attracted extensive attention for its well permeability and biocompatibility. The methods of gene therapy can be divided into direct and indirect method. The stem cell therapy, which is the most-well studied one, belongs to the indirect method. In the gene therapy of AD, the selection of appropriate carrier and method will determine the therapeutic effect.

Evaluation on the performance of clinical laboratory automation system / 中华检验医学杂志

Objective By analysis of the key performance indexes of the clinical laboratory automation system, to clarify the advantage and optimize the comprehensive performance of the laboratory automation system.Methods Key performance indexes were Collected from January 2017 to April 2017 in biochemistry and immunoassay group of Clinical Laboratory of Shanghai Tong Ren Hospital.(1)The data were collected and compared by the before-and-after method,the starting time of the automation system and initial sample test were analyzed.(2)Key performance indexes were analyzed for the time of specimen registration,inspection,and reporting.(3)The specimen turnaround time(TAT)was analyzed based on two months operation of the laboratory automation system.In view of disadvantage of infectious assays, setting up priority sample absorption, then TAT performance was re-evaluated.(4)By the assessment of total serum dosage required in the automation system, the number of blood vacuum tubes were reduced reasonably.The pros and cons of laboratory automation system were analyzed and the potential improvement were proposed.Results (1)According to the sample peak shift forward,the system start time could move forward 30 minutes earlier.(2)With the adopting of railway logistics,the specimens were sent to the lab and the registration time was at 7:25 am,and the time required for specimen delivery was greatly reduced which made specimen test,report and audit time all moved forward accordingly.(3)Data has shown that specimen TAT declined dramatically based on the performance of the first two month operation of the automation system,biochemical items were shortened 2 h,and the immunoassay shortened 4 h,respectively.Moreover the trend keeps better gradually.With setting up priority absorption infectious tests,the TAT was improved greatly,TAT reduced the average by 40 min.(4)500 μl(including the sample in dead space of vacuum tube)were needed for all the 65 biochemical items included in the system, and 1 495 μl serum were used for the 28 immunoassay.As a result, a total of 2 000 μl serum will be enough for sample analysis by the system, which provided the feasibility to reduce 3 vacuum tubes averagely.Considering the current automation system does not include all the analysis items in our lab directory, a few tests remain to be performed on offline instruments respectively.The methodology for some infectious agents are different from previous method, therefore some test results may need a period of time for comprehensive clinical appreciation.Furthermore,due to the parallel connection of multiple instruments included in the system, more rigorous and frequent quality control becomes a necessity,which may rely on more strict quality control procedure to guarantee the quality.Conclusions The application of the automation system significantly enhanced the efficiency of clinical laboratory all round.In addition, by the quantitative indicators, it is possible to monitor the system operation performance real time, which may feedback and facilitate the improvement constantly,and result in auto confirmation the majority results,eventually.

Efficacy of Baclofen Combined with Esomeprazole and Mosapride on Refractory Gastroesophageal Reflux Disease / 胃肠病学

Background:Gastroesophageal reflux disease( GERD)that does not respond satisfactorily to standard proton pump inhibitor is defined as refractory gastroesophageal reflux disease( rGERD). Combined therapy is used to treat rGERD, however,the addition of baclofen is rarely studied. Aims:To investigate the efficacy of baclofen combined with esomeprazole and mosapride on rGERD. Methods:Seventy-two patients with rGERD from March 2013 to April 2014 at the First Hospital of Putian City were enrolled and randomly divided into group A and group B. Patients in group A were orally administrated with esomeprazole 20 mg bid + mosapride 5 mg tid + baclofen 5 mg tid. Patients in group B were treated with esomeprazole 20 mg bid + mosapride 5 mg tid. The treatment course was 8 weeks. The efficacy on symptoms, esophagitis under endoscopy and adverse effects were compared between the two groups. Results:After 8-week treatment, score of heartburn,regurgitation,retrosternal pain,dysphagia and overall symptom were significantly decreased in the two groups than before the treatment. The overall symptom alleviating rate was significantly higher in group A than in group B (90. 6% us. 70. 0%;χ2 =4. 585,P=0. 032). Esophagitis under endoscopy in the two groups was significantly improved, the effective rate was significantly higher in group A than in group B(93. 8% us. 75. 0%;χ2 =4. 500,P=0. 034). The main adverse effects of baclofen were somnolence,dizziness and fatigue,all the patients were well tolerated. Conclusions:Baclofen combined with esomeprazole and mosapride is an efficient option for rGERD.

Fast onset of action of sublingual immunotherapy in dust mite caused allergic rhinoconjunctivitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate whether sublingual immunotherapy(SLIT) can take effect during the early phase in allergic rhinoconjunctivitis.@*METHOD@#Sixty subjects diagnosed as allergic rhinoconjunctivitis were enrolled and divided into the SLIT group and the control group. The daily symptom and medication scores were recorded and analyzed.@*RESULT@#After 4 weeks treatments, the daily symptoms score had significantly reduced in SLIT group(P 0.05). Whereas, the daily symptoms score and daily medication score in control group had shown changes with fluctuations. The correlation analysis had indicated that the daily medication score in the control group had a significant negative correlation with the daily symptom score (F = 554.9, P < 0.01). No serious adverse events occurred in this study.@*CONCLUSION@#SLIT could take effect in patients with allergic rhinoconjunctivitis sensitive to house dust mite as fast as the 4th week.

Coblation plasma surgery system in the treatment of perennial allergic rhinitis / 中国耳鼻咽喉头颈外科

OBJECTIVE To compare the effect and safety of coblation plasma surgery and beclomethasone dipropionate nasal spray in the treatment of perennial allergic rhinitis. METHODS A stratified,randomized,controlled trial of surgery and medicament was performed in the treatment of perennial allergic rhinitis. A total number of 102 patients were involved in the trial,including 56 cases with swelling of inferior turbinate,28 cases in surgery group,28 cases in medicament group; and 46 cases without swelling of inferior turbinate,23 cases in surgery group,23 cases in medicament group. Coblation plasma surgery was performed in all surgery groups. Each patient was given 50?4?2 ?g/d of beclomethasone dipropionate nasal spray in all medicament groups,Treatment time was 3 months. The symptom scores (SS)and visual analogue scale(VAS)were recorded. RESULTS Effect assessment showed that both methods had significant repressive effect on allergic symptoms,the effect of surgery group was better than that of medicament group at the 14th day,28th day and 3th month in cases with swelling of inferior turbinate. Difference between the surgery group and medicament group in cases without swelling of inferior turbinate had no statistic significance. CONCLUSION Both coblation plasma surgery and beclomethasone dipropionate nasal spray are effective to treat perennial allergic rhinitis. But coblation plasma surgery is better than medicament in cases with swelling of inferior turbinate.
