Kaposi sarcoma-associated herpesvirus (KSHV),also known as human herpesvirus 8 (HHV-8),is discovered in 1994 from Kaposi's sarcoma (KS) lesion of an acquired immunodeficiency syndrome (AIDS)patient.In addition to its association with KS,KSHV has also been implicated as the causative agent of two other AIDS-associated malignancies:primary effusion lymphoma (PEL) and multicentric Castleman's disease (MCD).KSHV is a complex DNA virus that not only has the ability to promote cellular growth and survival for tumor development,but also can provoke deregulated angiogenesis,inflammation,and modulate the patient's immune system in favor of tumor growth.As KSHV is a necessary but not sufficient etiological factor for KS,human immunodeficiency virus (HIV) is a very important cofactor.Here we review the basic information about the biology of KSHV,development of pathogenesis and interaction between KSHV and HIV.

The myelodysplastic syndrome(MDS) comprise a heterogeneous group of clonal disorders.A unique aspect of MDS is the notion that both bone marrow failure and the propensity toward development of acute leukemia coexist. Origin of abnormal clone with MDS occurs at the level of multipotent progenitors or above it. Recently some kinds of MDS were observed the abnormal clone has been potentially originated from normal CD+34 CD-38 Thy-1 + hematopoietic stem cells. The abnormal clones with different chromosomal abnormality have different distribution. With the propotion of abnormal clonality increasing MDS has aggravated. Coherent result will provide new insight into the clinical diagnosis, treatment and prognosis of MDS by strengthening the research of MDS clonality.

Abstract?AIM: To discuss clinical efficacy and safety of 10g/L atropine with short covering for children with amblyopia.?METHODS: Eighty -eight children ( 88 eyes ) with amblyopia, staying in hospital from February 2011 to February 2014 for treatment, were divided into control group ( n =44 ) and observation group ( n =44 ) . The control group only given short covering therapy was observed.Observation group was given 10g/L atropine treatment besides covering.Clinical efficacy, treatment compliance, visual acuity, corrected spherical degree of amblyopia eye and adverse events were observed and compared.?RESULTS:1) After treatment, total effective rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group ( 80%, 35/44, P<0.05 ); 2 ) excellent compliance rate of the observation group was 95% ( 42/44 ) , significantly higher than that of control group (82%, 36/44, P<0.05);3) visual acuity of the two groups when the disease was first diagnosed was not significantly different (P>0.05), but increased number of lines of vision and corrected spherical degree of amblyopia eye in the observation group were significantly higher (P<0.05);4) in the observation group total rate of adverse events was 9% ( 4/44 ) , significantly lower than that in the control group (23%, 10/44, P<0.05).?CONCLUSION: The combined therapy, 1% atropine with short covering, is effective and safe for amblyopia in children.

To study the influence of 5?-reductase on the pathogenesis of human benign prostatic hyperplasia (BPH), the activity of this enzyme was measured in mechanically separated stroma and epithelium from 7 normal and 16 hyperplastic prostates. Samples were incubated in the presence of tritium labelled testosterone. The yield of DHT was used to estimate the enzyme activity. The results showed that the specific activity of the enzyme (pmol DHT / mg protein/30 rain) was91.4?18,1 and 28.6?7.4 in stroma (S) and epithelium (E) of BPH, 44.7?8.9 and 23.9?6.8 in S and E of normal prostates respectively. It indicated that the enzyme is predominantly localized in the stroma and is elevated ia BPH, the primary abnormality of BPH is in the stroma and the increase of 5?-reductase may have some contribution to the pathogenesis of BPH.

Objective:To explore the application value of combined detection of troponin I (cTnI) and creatine kinase isoenzyme mass (CKMBmass), interleukin-6 (IL-6) and fibrinogen degradation products (FDP) in the diagnosis and treatment of acute myocardial infarction (AMI).Methods:A total of 102 AMI patients in Wanbei Coal Power Group General Hospital from July 2019 to June 2020 were selected as the AMI group. In addition, 60 patients diagnosed with chest pain (CP) and chest distress (CD) during the same period were selected as the CPCD group, and 60 healthy patients were selected as the healthy control group. The levels of cTnI, CKMBmass, IL-6 and FDP in the peripheral blood of the three groups were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of cTnI, CKMBmass, IL-6, and FDP. The AMI group was given thrombolytic therapy. The clinical data of patients with different curative effects, the trend of changes in peripheral blood cTnI, CKMBmass, IL-6 and FDP levels before and after treatment were compared, and the relationship between the above indicators and clinical indicators and curative effects were analyzed.Results:The levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in the AMI group were higher than those in the CPCD group and the healthy control group, and the levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in CPCD group were higher than those in the healthy control group ( P<0.05). The area under the curve (AUC) values of cTnI, CKMBmass, IL-6 and FDP in the combined diagnosis of CPCD and AMI were 0.898 and 0.926, respectively, which were higher than those of single diagnosis. The time from onset to thrombolysis, infarct location, diabetes, diastolic blood pressure (DBP), systolic blood pressure (SBP), left ventricular end systolic volume (LVESV), left ventricular end systolic diameter (LVESD), left ventricular end diastolic volume (LVEDV), left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) on admission of effective patients and ineffective patients were statistically significant ( P<0.05). The levels of peripheral blood cTnI, CKMBmass, IL-6, and FDP of effective patients were lower than those of ineffective patients when they were admitted to the hospital and 6, 12, 24, 48, and 72 h after treatment ( P<0.05). The peripheral blood cTnI, CKMBmass, IL-6, and FDP on admission were positively correlated with DBP, SBP, LVESV, LVESD, LVEDD, LVEDV, and was negatively correlated with LVEF ( P<0.05). Multiple linear stepwise regression analysis showed that after the onset to thrombolysis time, infarct location, smoking, diabetes, SBP, DBP, LVESV, LVESD, LVEDD, LVEDV, LVEF and other factors at admission were controlled, the levels of peripheral blood cTnI, CKMBmass, IL-6, FDP were still significantly related to the efficacy ( P<0.05). Conclusions:The peripheral blood cTnI, CKMBmass, IL-6, and FDP are all abnormally expressed in AMI patients. Combined detection has clinical significance for the diagnosis and treatment of AMI.

Objective To explore the role of mitogen-activated protein kinase(MAPK)in lipopolysaccharide(LPS)-induced iNOS expression and NO production in rat Schwann cells by the use of inhibitors PD98059 selective for extracellular signal-regulated kinase 1/2(EPK1/2), SB202190 for P38 MAPK and SP600125 for the c-Jun NH_2-terminal kinase (JNK). Methods Schwann cells were pretreated with PD98059 (30, 50, 70?mol/L), SB202190 (10, 20, 40?mol/L) and SP600125 (10, 30, 50?mol/L) at the indicated concentrations for 1 hour before the stimulation with LPS (10mg/L) for 4 hour. The estimation of iNOS mRNA, IL-6 mRNA and TNF-? mRNA was performed by RT-PCR; the changes of iNOS protein expression were investigated by Western blotting. The NO level was observed with measurement of nitrite in the cell culture medium. Results LPS could significantly activate MAPK signal pathway and lead to the expression of iNOS and NO production. The iNOS expression and NO production induced by LPS stimulation were significantly inhibited by the three highly specific inhibitors of MAPK. In addition, the inhibitors decreased LPS-induced the expression of IL-6 mRNA and TNF-? mRNA. Conclusion Activation of MAPK pathway is involved in iNOS expression and NO production in rat Schwann cells, and the inhibition of the signal transduction pathway can be effective to reduce the production of iNOS and NO, which may be a useful strategy against inflammatory and immune reaction after peripheral nerve injury.
