1.Regulating effect of graft-versus-host-disease and graft-versus-leukemia
Chinese Journal of Tissue Engineering Research 2007;0(31):-
Through thorough understanding of the pathophysiology of graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect, especial the effects of immune cells and cytokines, the article is designed to find out multiple ways to reduce GVHD and reserve or enhance GVL effect. Many kinds of cytokines are involved in the pathophysiologic mechanisms of GVHD and GVL effect. Different cytokines have different effects on GVHD and GVL effect. Immune cells play important roles in regulating GVHD and GVL effect. Studies shows that some cytokines and specific immune cells are able to reduce GVHD, as well as reserve or enhance GVL effect at the same time, which make the separation of GVL from GVHD can be achieved. On the whole, through thorough understanding of the mechanism of immune cells and cytokines in GVHD and GVL effect, we can find out multiple ways to reduce GVHD, as well as reserve or enhance GVL effect.

4.Allogeneic hematopoietic stem cell transplantation for the treatment of chronic myeloid leukemia in blast crisis
Journal of Leukemia & Lymphoma 2013;22(6):330-335
The treatment for chronic myeloid leukemia is still a challenge,at present.Tyrosine kinase inhibitors can partially control chronic myeloid leukemia in blast crisis (CML-BC),but the effect is not durable.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only way that can cure CML-BC.This paper presents a review of the treatment before allo-HSCT for CML-BC,the selection of condition regimen,donor and hematopoietic stem cell,the monitoring of MRD post-transplant,the prophylaxis and intervention of relapse.
5.Survey and Analysis on the Influence Factors of Interns’ Rational Drug Use on Patients
China Pharmacy 2001;0(09):-
OBJECTIVE:To study influence factors of medical students’rational drug use in clinical practice and to provide references for improvement of medical educations and rational drug use. METHODS:The information was obtained by 325 designed questionnaire"questionnaire for prescription behaviors of medical students’rational drug use"performed by students in two medical colleges of Jiangxi Province and was inputted using Epidata3.0 software. SPSS13.0 software was adopted to analyze data by means of descriptive statistical analysis and multiple linear regression analysis methods. RESULTS & CONCLUSIONS:The level of medical students’rational drug use was just a little below the average level. It was positive correlated to the self-evaluation on instructors’conducting frequency and the achievements in medical course,but with negative correlation to the performances of rational drug use knowledeg. The achievements in medical course in self-evaluation has great impact on rational drug use behaviors while the performances of rational drug use knowledge has little impact on it.

OBJECTIVE To evaluate the role of real-time fluorescent quantitative PCR assay in the early diagnosis of invasive aspergillosisi(IA) after allo-hematopoietic stem cell transplantation.METHODS All 123 serum samples from 18 IA patients and 38 no-invasive fungal infection(IFI) patients were detected by TaqMan-based real-time PCR to explore the cutoff of this array,while the primer and probe could amplificate five major Aspergillus species including A.fumigatus,A.flavus,A.niger,A.terreus and A.oryzae.RESULTS The optimal value could be acheived while the cutoff was set as two or more consecutive sample DNA≥15pg/?l in a week,and the sensitivity and specificity was 94.4% and 100.0%,respectively.CONCLUSIONS Real-time fluorescent quantitative PCR is helpful in early diagnosis of invasive aspergillosis.

Taxoid 14?-hydroxylase directs a side-route of taxol pathway that leading to a large number of 14?-hydroxy taxoid side products. A RNAi vector was used to suppress the expression of taxoid 14?-hydroxylase (14OH) gene in Taxus?media suspension cells. The dsRNA expression unit was introduced into Taxus?media cells via Agrobacterium tumefaciens-mediated transformation approach. PCR-Southern blot analysis of transgenic cells showed that the dsRNA unit was integrated into the genome of Taxus?media. The levels of transcripts for 14OH gene in transformed and the control cell lines were determined by using RT-PCR method. In addition,the yield of taxoids were analyzed by HPLC. The transcription of 14OH gene was suppressed and the total amount of three C-14 oxygenated taxoids (yunnanxane,sinenxan A,sinenxan C) in Taxus?media transgenic cell lines reduced significantly as compared to those in the non-transgenic control. Inhibition of the 14OH gene via RNAi might provide a new way to enhance the production of Taxol in Taxus cells.

Objective To assess the effect of Ambroxol combined with Naloxone on respiratory insufficiency on premature infants. Methods A total of 168 premature infants treated from 2006 to 2009 in our hospital were divided into two groups randomly. Additionally to the conventional treatment, Ambroxol (5 mg pertime) combined with Naloxone (0.1mg pertime) intravenously injected 2 to 3 times one day for 3 to 5 days in the treatment group(86 cases). The control group (82 cases) was treated by routine Aminophylline injection,3- 5 mg/kg pertime, 2 to 3 times one day. Respiratory rates, regulately or not,breathholding, cyanosis and apnea,mechanically ventilated time,time of oxygen inhaling, time of hospital stay and the overall response rate were measured. Results The overall response rate was 80% (69/86) in the treatment group and 56% (46/82)in the control group, with significant difference between the two groups ( P < 0. 05 ). Mechanically ventilated time,time of oxygen inhaling and hospital stay in the treatment group was (110.5±45.1) hrs, (169.3±58.6) hrs and ( 12±3) days, which were all significantly lower than that in the control group ( 181.1±81.2) hrs, (236.6±87.8)hrs and (16±5)days,respectively(P<0.01 or 0.05). Conclusion Ambroxol and Naloxobe additional to conventional treatment could improve the respiratory function in premature infants with respiratory insufficiency safely with less side effects. Moreover,breathing machine could be removed to some extent,which made it more applicable in primary hospitals.

Objective To explore the clinic effect of arthroscopic in the treatment of Haglund deformity.Methods Sixteen patients with Haglund deformity were treated with arthroscopy from June 2009 to December 2011,including 7 males and 9 females,with an average age of 28.8 years (range,17-39 years).All 16 patients were suffered ankle back pain,exacerbations of pain during active and passive plantar flexion.This group of patients was chosen arthroscopic surgery to treat Haglund deformity as conservative treatment was invalid.With the prone position for surgery,we selected two approaches next to the Achilles tendon.Use the C-arm X-ray fluoroscopy observed calcaneus orthopedic during the operation.From the posteromedial approach to the posterolateral approach to alternately use the shaver and ArthroCare to clean up the front of the inflammation of the Achilles tendon bursa,by which could form arthroscopic operations security zone.All operating equipment was on the back toward the Achilles tendon,which could maximize the protection Achilles tendon.Postoperative plaster or brace short brake was used for two weeks.16 cases of postoperative patients were followed up; the mean follow-up time was 13 months (9-18 months).According pain visual analogue scale (VAS) and the American Orthopaedic Foot and Ankle (AOFAS),the clinic effects were evaluated.Results At the last follow-up,the AOFAS hindfoot score of 91.5±2.8 was significantly higher than the preoperative 71.0±3.7 (t=17.38,P=0.014),postoperative VAS score 1.3±0.6 was significantly lower than the preoperative 5.10±0.44 (t=19.20,P=0.022).Conclusion The treatment of Haglund deformity by means of arthroscopic minimally invasive,with smaller trauma,faster recovery and lower complications,is effective and safe in clinical practice.However,dues to its steep learning curve,this method requires doctors to carry out who had relatively large arthroscopic surgery experience.
