A 51-year-old man presented with a 4-month history of upper abdominal distending pain and 1-month history of cutaneous nodules and plaques on the neck, trunk and bilateral thighs. The patient underwent many gastrointestinal tract examinations in several local hospitals, and symptomatic treatment did not work. The biopsy of nodules on the abdomen revealed medium- to large-sized atypical lymphoid cells within numerous small vessels in lower dermis and subcutaneous fat tissue. Additionally, the atypical cells were present exclusively within vascular lumina. Immunohistochemical labeling showed the reactivity of neoplastic cells to CD2, CD99, CD3ε, CD43, CD56, Epstein-Barr virus-encoded small nuclear RNAs (EBER), and cytotoxic proteins such as T-cell intracellular antigen-1 (TIA-1) and perforin, but not to CD4, CD8, CD20, CD79a,CD30, cytokeratin (CK), S100, or CD68. The endothelial cells lining the involved vessels exhibited the reactivity to CD31 and CD34. Based on the above findings, the patient was diagnosed with intravascular NK/T-cell lymphoma firstly manifesting as gastrointestinal tract symptom and complicated by skin lesions. Following combined chemotherapy with cyclophosphamide, daunorubicin, vincristine, prednisone and etoposide, the patient experienced a quick and satisfactory recovery and the follow-up still continued.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Objective To detect brain natriuretic peptide(BNPs) level in serum in order to confirm its applical value.Methods Forty-eight patients with congestive heart failure(CHF) were chosen,which included 36 patients with pneumonia,12 patients with congenital heart diseases.Forty heathy children were chosen as control group.BNPs level of two groups were detected by enzyme label.Results The level of BNP in patients with CHF(that′s positive group) was obviously higher than that in control group in the stage of CHF and recoverty(t=14.30,20.38 all P0.05),this included that the cardiac function had significantly changes in the stage of CHF,at the same time,the level of BNP had negative correlation to CI and LVEF(r=-0.61,-0.79 all P

OBJECTIVETo compare the effects of puerarin and granulocyte colony-stimulating factor (G-CSF) in treating acute myocardial infarction (AMI) and on the size of infarcted area and cytokines.

METHODSSeventy-nine patients with anterior AMI were randomly divided into three groups, they were treated with conventional Western medical treatment, but to the puerarin group (PG) and the G-CSF group (GCG) puerarin and G-CSF was given additionally, respectively. The infarcted size, plasma G-CSF, matrix metalloproteinase-9 (MMP-9), serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) were detected before and after treatment.

RESULTSThe infarcted size was positively correlated to the levels of G-CSF, MMP-9, IL-6 and TNF-alpha before treatment ( r = 0.45, 0.42, 0.44 and 0.42, P<0.01 ). The infarcted size in the PG and the GCG decreased on the 28th day (P<0.01), the level of G-CSF, MMP-9, IL-6 and TNF-alpha in the PG on the 7th day all decreased (P<0.05), but these indexes in the GCG increased (P<0.05), while those in the control group were unchanged (P>0.05).

CONCLUSIONPuerarin and G-CSF are effective in decreasing infarcted size, but their effects on cytokines are different entirely.

OBJECTIVETo explore the influence of the DNA repair gene ERCC2 single nucleotide polymorphisms (SNPs) rs13181, rs1618536, and rs1799793 on male idiopathic infertility in Ningxia, China.

METHODSUsing MassArray, we conducted a case-control study and genotyped three ERCC2 SNPs rs13181, rs1618536, and rs1799793 for 351 males (aged 31.0 +/- 4.2 years) with idiopathic infertility and another 327 normal fertile men (aged 33.0 +/- 5.9 years) as controls.

RESULTSThe ERCC2 AnyG-anyA-anyA genotypes were significantly associated with an increased risk of idiopathic infertility (OR 0.414, 95% CI 0.176 - 0.970), while the three single ERCC2 SNPs rs13181, rs1618536, and rs1799793 showed no significant differences between the cases and controls (P > 0.05).

CONCLUSIONThe ERCC2 SNPs rs13181, rs1618536, and rs1799793 play a role of interaction in male idiopathic infertility in Ningxia, contributing to the risk of the disease.

Objective To explore the changes of cardiac muscle enzymogram and heart function before and after transactheter closure of ventricular septal defect(VSD).Methods The serum levels of cardiac troponin(cTnI),carcatine kinase(CK),lactie dehydrogenase(LDH),aspartate aminotransferase(AST)and the left ventricular ejection fraction(LVEF)were detected by two-dimensional echocardiography,and the change before and after intervention was analyzed.Results The serum level of cTnI in VSD patients after treatment was markedly higher than that before intervention[(0.29?0.17)?g/L vs(0.02?0.01)?g/L,t=9.0 P0.05).Conclusion Catheterization to treat VSD may have influence on enzymogram and the heart function,which may be related to the minor myocardial damage during the operation.

Objective To explore the activation and function of Janus protein-tyrosine kinase (JAK)/ signal transducer and activator of transcription (STAT1) signal transduction pathway in kidney,lung and brain of MRL/lpr mice.Methods MRL/lpr mice with systemic lupus erythematosus (SLE) were studied at the age of 12 weeks up.Non-SLE MRL/lpr mice were used as controls.We used phosphospecific antibodies to detect STAT1 activation in kidney,lung and brain by immunohistochemistry and Western blots.Gene expression of the STAT induced feedback inhibitors of cytokine signaling 1 (SOCS-1) was investigated by SYBR green I real-time reverse transcriptase polymerase chain reaction (PCR).Results Phosphorylation of STAT1 protein was markedly activated in these three organs,although renal and pulmonary STAT1 activation were much more evidently activated.SOCS-1 gene expression increased in all three organs,while renal SOCS-1 gene expres- sion increased less than lung and brain.Conclusion The activation of JAK/STATI signal transduction path- way may be pathogenic in the organ involvement and progression of SLE.The pathogenesis of lupus nephritis may also be associated with the down-regulation of SOCS-1 feedback inhibition.

OBJECTIVETo observe the protective effect of Acanthopanax senticosus saponins (ASS) on myocardial ischemia-reperfusion injury in rats.

METHODThe myocardial ischemia-reperfusion model was induced by 30 min left anterior descending coronary occlusion and 120 min reperfusion in rats. The changes of myocardial infarct size (MIS), the serum creatine phosphokinase (CK) and lactate dehydrogenase (LDH) activity, the serum lipid peroxidation (LPO) content and superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity and plasma endothelin (ET), angiotensin II (Ang II), prostacycline (PGI2) and thromboxane A2 (TXA2) levels and myocardial free fatty acid (FFA) content of infarct and noninfarct area were determined.

RESULTIn rats treated by ASS (in a dosage of 25, 50 and 100 mg x kg(-1) i.v. at 30 min after coronary occulusion), the MIS was significantly reduced, the serum CK and LDH activity, the plasma ET, Ang II and TXA2 level and myocardial FFA content declined, while plasma PGI2 level and PGI2/TXA2 was increased signficantly. In addition, serum LPO content declined, SOD and GSH-Px activity were increased markedly.

CONCLUSIONASS has protective effect on myocardial ischemia-reperfusion injury, which may be due to its function of improving free radicals and myocardial metabolism, decreasing plasma ET, Ang II and TXA2 levels and increasing plasma PGI2 level and PGI2/TXA2 ratio etc.

OBJECTIVETo investigate the clinical and pathological characteristics, treatment methods, and prognosis of synchronous primary cancers of the endometrium and ovary.

METHODSThe clinical data of 43 patients with synchronous primary cancers of the endometrium and ovary were retrospectively reviewed. The survival was calculated by Kaplan-Meier method and compared using the log-rank test.

RESULTSThe median age at diagnosis was 49 years (range, 28-73 years). The most common symptoms were abnormal vaginal bleeding (69.8%) and abdominal or pelvic pain (44.2%).Pelvic masses were found in 39.5% of the patients and enlarged corpus in 27.9% at physical examination, while pelvic masses were found in 67.4% of the 43 patients (29 cases) and thickening or abnormal endometrium in 23.3% (10 cases) during ultrasound examination. Of 25 patients examined by CT/MRI, pelvic masses were found in 13 cases and enlarged uterus in 11 cases. All 15 patients who underwent endometrial biopsies were proven to have endometrial carcinomas. Serum CA125 level was found to be elevated in 22 of the 34 examined cases (64.7%) with a median value of 500 U/ml (range, 39-3439 U/ml). FIGO stages of endometrial carcinomas: IA 18 cases, IB 20 cases, IC 2 cases, IIA 3 cases; Stages of ovarian carcinomas: IA 19 cases, IB 4 cases, IC 7 cases, II 4 cases, III C 9 cases. Twenty-four patients (55.8%) were in stage I both endometrial and ovarian carcinomas. Thirty-one patients underwent total hysterectomy plus bilateral salpingo-oophorectomy with omentectomy and appendectomy, meanwhile, 12 patients had pelvic lymph node dissection. Thirty-eight of the 43 patients (88.4%) had a pathologically proven endometrial adenocarcinoma. The predominant ovarian histology was endometrioid or mixed tumor with endometrioid components (30/43, 69.8%). Postoperatively, 26 patients (60.5%) received adjuvant chemotherapy alone, 12 had chemotherapy plus radiotherapy, only one patient had radiation alone and the remaining 4 cases received no adjuvant treatment. The 3- and 5-year survival rates of the group were 87.4% and 71.1%, respectively. The 3- and 5-year survival rates of patients with both endometrioid and ovarian carcinomas were higher than that of those with non-endometrioid or mixed subtypes (93.8%, 82.0% vs. 79.7%, 69.0%). The 3-year and 5-year survival rates of patients with early stage disease were better than those of the other patients (93.3%, 93.3% vs. 69.7%, 36.7%). Recurrence developed in 15 patients (34.9%). It was showed by univariate analysis that lower CA125 level, early FIGO stage, and adjuvant chemotherapy plus radiotherapy significantly and positively affect the 5-year survival rates, while only early FIGO stage and chemotherapy plus radiotherapy were revealed by multivariate analysis as independent prognostic factors.

CONCLUSIONSynchronous primary cancers of the endometrium and ovary are different from either primary endometrial carcinoma or ovarian cancer, while it can usually be detected in early stage and with a good prognosis. The impact of the CA125 level on prognosis needs to be further studied. Surgical treatment alone may be enough for early stage patients. Chemotherapy plus radiotherapy may be necessary for advanced stage patients.

OBJECTIVETo study serum levels of brain natriuretic peptide (BNP) in children with Kawasaki disease (KD) and the correlation between BNP levels and the heart function.

METHODSForty-three children with KD and thirty healthy children were enrolled. Serum levels of BNP were measured using ELISA. KD children received an echocardiographic examination, including measurements of left ventricular ejection fraction (LVEF), left ventricular shorten fraction (LVSF), cardiac index (CI) and left ventricular inflow velocity through the mitral annulus.

RESULTSMean serum level of BNP at the acute stage in children with KD was significantly higher than that at the recovery stage as well as the control group (p<0.01). The LVEF, LVSF and CI levels at the acute stage were significantly lower than those at the recovery stage in children with KD (p<0.05). The linear regression analysis showed that the BNP level was negatively correlated with the levels of LVEF, LVSF and CI (r=-0.63, -0.52, -0.53, p<0.05).

CONCLUSIONSThe serum BNP levels increase significantly in KD children at the acute stage, and are negatively correlated with the levels of LVEF, LVSF and CI. Measurement of serum BNP level is useful for the early diagnosis of KD.
