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.

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.

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.

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.

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.

Objective To compare the operation situation of pancreatico duodenectomy (PD) and pylorus‐preserving pancreatico duodenectomy (PPPD) ,and analyze the clinical efficacy of PPPD .Methods Data of 47 patients with periampullary carcinoma and pancreatic head carcinoma underwent pancreatico duodenectomy from January 2010 to December 2013 were retrospectively analyzed and divided into PPPD group (20 cases) and PD group (27 cases) according to different surgery method .Then compare the situa‐tion of intra‐operative and post‐operative situation in two groups of patients .Results The operation time of PPPD group was sig‐nificantly lower than that of PD group (P<0 .05);the incidence of postoperative complication rate of PPPD group was obviously lower than PD group (P< 0 .05);and postoperative infection rate of PPPD group was significantly lower than PD group (P<0 .05);there was no significant difference between two groups in pancreatic leakage ,bile leakage ,gastrointestinal leakage ,post oper‐ative bleeding ,mortality and the incidence of delayed gastric emptying after surgery (P>0 .05) .Conclusion PPPD operation could shorten the operation time ,promote post‐operative recovery ,lower complication rates and shorten hospitalization time ,and could al‐so help to improve the nutritional status of patients ,improve the postoperative quality of life of patients ,thus it should be further promoted .

Abstact:Aim To identify whether the petroleum e-ther fraction of Yueju pill (YJ-PE)could exhibit a po-tent rapid antidepressant effect and to investigate the underlying biological mechanism involved.Methods Fourty-four male KM mice were randomly assigned to five groups:the control group (saline group),low dosage of YJ-PE,middle dosage of YJ-PE,high dos-age of YJ-PE and ketamine.After a single drug admin-istration,we used tail suspension test (TST)to test the rapid antidepressant effect of YJ-PE in KMmice at 30 min.Another twenty-four male KM mice were ass-inged to three groups:control group,screened effective low dosage of YJ-PE group and ketamine group.We usd TST to assess these mice at 24 h post a single ad-
ministration.Western blot was performed to examine the expression of BDNF and TrkB in hippocampus of KMmice at 30 min and 24 h post a single administra-tion.Results An acute administration of YJ-PE de-creased the immobility time of KMmice in TST and in-creased the expression of BDNF and TrkB as soon as 30min post a single administration and lasted at least for 24 hours.Conclusion YJ-PE (low dosage)ex-hibits a rapid antidepressant-like potent,and the po-tent rapid antidepressant effects of YJ-PE are associat-ed with the up-regulation of BDNF and TrkB.

Objective To analyze the serum samples of young and middle-aged patients with hypertension of different syndromes and healthy patients by means of metabonomics; To confirm its biomarker; To reveal the nature of phlegm dampness retention syndrome in essential hypertension. Methods The syndrome types of 34 hypertension patients were differentiated into 14 cases of liver-fire hyperactivity syndrome group, 14 cases of phlegm dampness retention syndrome group and 6 cases of yin deficiency and yang hyperactivity syndrome group. 15 healthy volunteers were selected as control group. 1H-NMR technique combined with partial least squares-discriminate analysis (PLS-DA) method was used to look for the biomarkers. And the levels of UA, TC and TG were recorded. Results The level of UA in phlegm dampness retention syndrome group was significantly higher than the other three groups (P<0.05). The level of TC in yin deficiency and yang hyperactivity syndrome group was higher and had significantly difference with the control group (P<0.05). The level of TG in phlegm dampness retention syndrome group was higher and had significantly difference with control group (P<0.05). The metabonomics study based on the 1H-NMR method could distinguish the phlegm dampness retention syndrome group from the normal control group, liver-fire hyperactivity syndrome group and yin deficiency and yang hyperactivity syndrome group. Compared with the control group, the levels of acetone, VLDL, and LDL were significantly higher and the levels of lactate, serine, glucose, methionine, alanine were significantly lower in phlegm dampness retention syndrome group; compared with the liver-fire hyperactivity syndrome group, levels of citrate, alanine, VLDL, and LDL were significantly higher and the levels of glucose, lysine, glutamate, proline lactate were significantly lower; compared with yin deficiency and yang hyperactivity syndrome group, the level of creatinine was significantly higher. Conclusion There are lipoprotein metabolism, amino acid metabolism and glucose metabolism disorder in the young and middle-age hypertensive patients with phlegm dampness retention syndrome.
