Viral infections remain a major cause of morbidity in patients with immunodeficiency,such as recipients of hematopoietic stem cell transplantation (HSCT).Adoptive transfer of donor-derived virusspecific cytotoxic T lymphocytes is a strategy to restore virus-specific immunity to prevent or treat viral diseases and has been tested in the clinical setting for more than 20 years.The 55th ASH annual meeting reported lots of basic and clinical experience about CTL and summarized lots of trails to evaluate it,which will give us some new thought about the antivirus therapy after HSCT.

Progress toward improving management of myelodysplastic syndromes (MDS) occurred every year.This review focused on the new developments of classification,diagnoses,prognostic stratification and therapy on MDS in recent five years.In addiction,a brief introduction of pediatric MDS was presented here.All this were for a better exploration in the future.

To investigate the expression change of BDNF in lamina II of spinal cord from partial deafferented cats, L6 segmentsof spinal cord from 20 adult male cats (5 normal cats, 15 unilateral L6 spared roots cats allowed to survive 3 d, 6 d and 12 d re-spectively) were stained with immunohistochemical technique. The results showed: BDNF positive products were mainly dis-tributed in nerve terminals, varicosities and few neurons of spinal cord lamina II in normal cat. After operation, the density ofpositive nerve terminals and varicosities began to decrease on the third day, reached the lowest level on the 6th day and recoveredto normal level on the 12th day on operated side. But the number of BDNF neurons showed no obvious change. The authors sug-gest that the decreased density of BDNF positive products in lamina II on the 3rd and 6th day was related with the degenerationof the nerve fibers and varicosities after section of the adjacent dorsal roots. On the 12th day, the remaining L6 dorsal roots un-derwent collateral sprouting compensatoryly and reestablished functional connection with target neurons. Therefore, BDNF maybe involved in the normal physiological function and the plasticity of spinal cord after damage.

Breast cancer is one of the most common tumors in the world. HER2 and anti HER2 monoclonal antibody (Herceptin) has been a focus of breast cancer study in recent years. It is believed that HER2 and anti HER2 monoclonal antibody (Herceptin) may be a novel independent prognostic marker and therapeutic target for breast cancer. Herceptin, anti HER2 monoclonal antibody, has been proved to be an effective agent for breast cancer in late stage diseases, recurrent and metastatic lesion.

Objective To investigate the effects of sensorimotor therapy on patients with knee osteoarthritis.Methods Ninety-two patients with knee osteoarthritis were divided into a treatment group and a control group by using random digits table. Both groups received conventional rehabilitation therapy, including knee isometric and isotonic contraction training, ultrashort wave diathermy as well as aerobic exercise. The treatment group was also administered with sensorimotor training, in addition to the conventional training,including the muscle strengthening and control training of quadriceps and hamstring muscle using sling exercise therapy system and on the Thera-band mattress. The visual analogue scale (VAS) for pain, manual muscle testing and knee range of motion as well as the Japanese Orthopedic Association knee function evaluation form were used to evaluate the patients. Results There was no statistic difference between the 2 groups before treatment, with regard to the evaluation parameters used in this study. After 2 months of treatment, both groups improved significantly (P ＜0.05),with the treatment group improved to a significantly greater extent (P ＜0.05). Conclusions Sensorimotor training in addition to the conventional rehabilitation treatment can further relieve the pain of patients with knee osteoarthritis joints arthritis and improve the function of patients with knee osteoarthritis.

Objective To investigate the cost-effect of tele-wound treatment platform with cellular phone terminator and traditional outpatient treatment on chronic lower limb ulcers in remote district.Methods Thirty seven cases with chronic lower limb ulcers from the key hospitals in the district of west Hunan Province were collected by cluster sampling,and randomly divided into the intervention group (25 cases)and the control group (12 cases).They chose remote wound treatment platform intervention with cellular phone terminator and traditional dressing change in clinic.All patients received a 1.5-year follow-up,or cure and amputations were set as the endpoint of the study.The cost-effect,including the incidence of complications in the course of treatment,number of switches,treatment time,the cost of treatment,as well as medical human resources consumption was analyzed and compared between the two groups.Results The incidence of complications in the course of treatment in the intervention was (76.0％) significantly lower than the control group(91.7％).There was a significant increase in the dressing times and the duration of treatment; and there was no significant difference in the cost of treatment and medical human resources consumption between two groups.Conclusions Compared to the traditional outpatients wound treatment,the multimedia message-based tele-wound treatment platform unlikely increased medical human resources consumption and the cost of treatment,and may reduce the incidence of complications and the treatment time.

Objective To analyze the correlation of interleukin(IL)-12B gene single nucleotide polymorphism(SNP)rs6887695 with clinical phenotypes(including age at onset,family history,clinical types,gender)of psoriasis vulgaris in Chinese Han population.Methods This study recruited 575 patients with psoriasis vulgaris and 1403 healthy controls.DNA samples were obtained from these subjects.PCR with Taqman fluorescent probe(ABI 7900 system)was performed to analyze the genotype of SNP rs6887695 in IL-12B gene.Statistical analysis was carried out by using the software SPSS 14.0,and Chi-square test was conducted to compare the frequency of the SNP rs6887695 genotypes and alleles between the patients and controls as well as between patients with different clinical phenotypes of psoriasis.Results The frequency of GG,GC and CC genotype of the SNP rs6887695 was 42.61％,45.39％ and 12.0％ respectively in the patients,compared to 34.42％,47.83％ and 17.75％ in the healthy controls(x2 =16.31,P ＜ 0.01);the frequency of G and C allele of the SNP rs6887695 was 65.30％ and 34.70％ respectively in the patients,compared to 58.34％ and 41.66％ respectively in the healthy controls(x2 =16.54,P＜0.01).Significant differences were observed in the distribution of genotypes and alleles of the SNP rs6887695 between patients with chronic plaque psoriasis(n =543)and those with acute guttate psoriasis(n =32,x2 =18.11,12.19,both P ＜ 0.01).Increased frequency of G allele and GG genotype of the SNP rs6887695 were noted in the patients with psoriasis vulgaris compared with the healthy controls,and in the patients with plaque psoriasis compared with those with guttate psoriasis.However,there was no statistical difference in the distribution of SNP rs6887695 genotypes or alleles between 540 patients with adult onset psoriasis and 35 patients with child onset psoriasis,between 102 patients with family history and 440 patients without family history,or between 341 male patients and 234 female patients(all P ＞ 0.05).Conclusions The IL-12B SNP rs6887695 may be associated with the susceptibility to psoriasis vulgaris in Chinese Han population,especially with the susceptibility to plaque psoriasis,but seems unassociated with the age at onset,family history or gender of patients.
