The myelodysplastic syndrome (MDS) is a clonal disorder characterized by inefficient haematopoiesis,dysplasia of hematopoietic cells in bone marrow and unable production of mature cells with normal differentiation resulting in peripheral cytopenias.The incidence of MDS is increased with the increasing age,suggesting that the accumulation of genetic or epigenetic changes lead to DNA mutations in hematopoietic stem cell,activation of oncogenes and inactivation of tumor suppressor genes,increasing limitless self-proliferation,and eventually resulting in aberrant clonal hematopoiesis and the occurrence of MDS.About thirty percentage of patients with MDS will transform into acute myeloid leukemia (AML) at last.MDS is always not sensitive to cytotoxic drugs,but targeted drugs maybe help to improve the prognosis.

JAK2 V617F gene mutation positive myeloproliferative neoplasms (MPN) consists of polycythemia vera (PV),essential thrombocythemia (ET) and primary myelofibrosis (PMF).This article focuses on their risk scoring systems and treatment including first-and second-line therapies,JAK2 inhibitors,cytoreduction,antifibrosis and other single-agent or combination therapy.

Objective To investigate the relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P ＜ 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P ＜ 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P ＜ 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ～ 0.48,P ＜ 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ～-0.51,P＜0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.

Objective To explore surgical options and clinical outcome of preperitoneal hernia repair (TAPP) and totally ext raperitoneal hernia repair (TEP) in inguinal hernia repair.Methods The clinical data of 302 patients underwent laparoscopic herniorrhaphy were retrospectively analyzed.Results None of patient s was changed to open operation.The TAPP and TEP outcome measures:the unilateral hernia surgery time from (31.2 ± 8.3) min and (55.3 ± 15.2) min,bilateral hernia surgery time was (46.2 ± 11.2)min and (80.2 ± 23.2) min; blood loss was (6.4 ± 2.0) ml and (7.2 ± 1.6) ml,bed activity for the first was (16.0 ± 1.8) h and (16.0 ± 1.5) h,hospital stay was (3.0 ±0.6) d and (3.1 ±0.8) d.Conclusions Laparoscope herniorrhaphy is safe due to lower recurrence and complications.It also has the advantages of slight pain and rapid recovery.

Objective To analyze cancer incidence and mortality in Fujian in 2012 and to provide sci-entific basis for tumor prevention .Methods In accordance with the methods and criteria of data quality control made by NCCR,7 regristries data qualified from 9 submitted regritries in Fujian after data assessment were mer-ged and analyzed.Results In 2012,the cancer incidence rate was 251.44/105 (308.44/105 in male and 193.03/105 in female),age standardized incidence by Chinese standard population (ASR China)and by world standard population(ASR world)were 205.15/105 and 201.11/105.The cumulative incidence(0~74 age)was 23.51%.The mortality rate was 161.85/105(220.87/105 in male and 101.37/105 in female).ASR China and ASR world were 128.54/105 and 127.70/105 the cumulative incidence(0~74 age)was 15.04%.The age-spe-cific incidence and mortality reached maximum value in 75 ages and 80 ages respectively .The top 5 cancer inci-dences were lung cancer ,stomach cancer ,liver cancer ,esophagus cancer and breast cancer .The top 5 cancer mor-tality were lung cancer ,liver cancer ,stomach cancer ,esophagus cancer and colorectum cancer .Conclusion Di-gestive malignancies ,lung cancer ,and breast cancer in female were the most frequent in Fujian province ,and the prevention and control for those cancers should be enhanced .

ObjectiveTo investigate the treatment effects of comprehensive nursing intervention on patients with chronic obstructive pulmonary disease(COPD) treated by non-invasive mechanical ventilation with BiPAP mode.Methods96 patients with diagnosed COPD and using non-invasive mechanical ven- tilation with BiPAP mode were randomly divided into the control group(46 cases) which was treated with routine measures and the comprehensive nursing intervention group (50 cases) which adopted comprehen- sive nursing intervention according to experimental design. The frightening degree, incidence rate of com- plications and clinical treatment effect by ventilator were compared between the two groups.ResultsPa- tients compliance with treatment and clinical treatment effect by ventilator in the comprehensive nursing in- tervention group was better than that of the control group. The frightening degree and incidence rate ofcomplications were lower than those of the control group (P < 0.01 ).ConclusionsComprehensive nurs-ing intervention with non-invasive mechanical ventilation with BiPAP mode can improve the treatmentcompliance of COPD patients,reduce complications followed by non-invasive mechanical ventilation andreach the prospective treatment effect.

Objective To explore the expression of cadherin (Cad) genes in patients with chronic myeloid leukemia (CML),and to elucidate the significance of Cad genes in the development of CML.Methods E-Cad and N-Cad gene expression levels in bone marrow mononuclear cells (BM-MNC) from 48 CML patients (29 in chronic phase,19 in progressive phase) were detected by real time quantitative polymerase chain reaction (qRT-PCR).Results Gene expression of E-Cad and N-Cad was detectable in CML BM-MNC.E-Cad gene expression level was lower in progressive CML than that in chronic CML (0.20 ± 0.35 vs 1.19 ± 0.87,P ＜ 0.01),while N-Cad was highly expressed in progressive CML than in chronic CML (0.89 ± 0.45 vs 0.57 ± 0.47,P ＜ 0.05).E-Cad gene expression level was negatively corrclatcd with thc pcrccntagc of peripheral blood progenitor cells (r =-0.705,P ＜ 0.01).Conclusion E-Cad and N-Cad gene expression correlates with the progression of CML,and might be used as an evaluation index for disease development.

Objective To study the relationship between the changes of ten elemental contents in serum and schizophrenia.Methods Calcium (Ca), magnesium (Mg), zinc (Zn), iron (Fe), aluminum (Al), arsenic (As), selenium (Se), copper (Cu), lead (Pb), manganese (Mn) in serum in the of schizophrenic patients and normal subjects are measured by inductively coupled plasma mass spectrometer and inductively coupled plasma emission spectrometer, compared the content of elements between the schizophrenia and normal.Results There were significant differences ( P<0.05) in other elements between two groups except lead.The contents of Ca,Fe,Mg,Zn,As,Se,Cu in the patients with schizophrenia were significantly lower than those in control, while Al, Mn were significantly higher than those in control.Most of elements in serum between case and control groups were correlated (P<0.05).Some of element ratios which have physiological significance were significant statistically (P<0.05), such as: Ca/Mg, Ca/Fe and so on.Conclusion These findings suggest that the patients with schizophrenia might have an abnormal elemental metabolism.Given the relationship among the elements, the element ratios are more valuable in reflecting the relationship between schizophrenia and elements.
