Objective To investigate the changes of hematoma and perihematomal edema in spontaneous hypertensive rats (SHRs),as well as the correlation between blood pressures and perihematomal edemaMethods A total of 24 6-month-old male SHRs were included.They were randomly divided into intracerebral hemorrhage 1-,3-,5-,and 7-day groups (n =6 in each group).Blood pressure was determined by tail-cuff sphygmomanometry.Collagenase Ⅳ was injected into caudate nucleus in order to induce a model of intracerebral hemorrhage.Magnetic resonance T2 weighted imaging was used to observe hematoma and perihematomal edema.Results On day 1 after modeling,the blood pressure was decreased significantly compared to that before modeling,and it was elevated gradually on day 3.Parallel profile test showed that the overall profile was parallel between the change rate of blood pressure and the change rate of perihematomal edema volume (F =2.820,P =0.063).The coincident profile test showed that both the overall profiles did not coincide (F =10.961,P =0.000).The change rate of systolic blood pressure was significantly positively correlated with the change rate of perihematomal edema volume (r =0.527,P =0.024) and the change rate of perihematomal edema volume (r =0.755,P =0.000) showed a significant positive correlation.Conclusions Brain edema appeared and expanded rapidly on the day of intracerebral hemorrhage in SHRs.It reached the peak on day 3,and then dissipated gradually.The blood pressure decreased significantly on day 1 after intracerebral hemorrhage,and it began to increase from day 3 till day 7.The changing trends of the blood pressure and perihematomal edema volume were parallel to each other,and the change rate of systolic blood pressure and the change rate of perihematomal edema volume showed a positive correlation.

Objective To study the correlation between single nucleotide polymorphisms of -238,-308 G/A in promoter region of tumor necrosis factor -?(TNF-?) gene and the type of juvenile idiopathic arthritis (JIA).Methods Clinical data and blood preparation of 127 children with JIA and 106 healthy children were evaluated.Subgroups of JIA were defined according to the Edmonton criteria.The -238 G/A and -308 G/A polymorphisms in DNA analysis in this study were extracted from the whole blood.The restricted fragment length polymorphisms were determined in the cases of all JIA children and control group.Results 1.The TNF-?-238 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 92.9% and 7.1%,and the control group was 95.3% and 4.7%.The distribution of allele frequencies was no significantly different between JIA group and control group(?2=1.149 P=0.284).But there were significant difference between polyarticular JIA (RF negative) and control group(?2=7.621 P=0.006).2.The TNF-?-308 G/A allele frequencies of JIA group and control group:allele frequency of JIA group was 94.1% and 5.9%,the control group was 95.3% and 4.7%.The distributions of allele frequencies was no significantly different between JIA group and control group(?2=0.322 P=0.571).There were significantly difference between polyarticular JIA (RF negative) and control group (?2=7.621 P=0.006).Conclusions The TNF-?-238,-308 polymorphisms of A in the-238 and-308 TNF-? gene are important to the joint destruction of JIA.The study will be beneficial to provide indirect support to the application of anti-TNF drugs to the treatment of JIA.

Objective To investigate the correlation between the single nucleotide polymorphism(SNP) of macrophage migration inhibitory factor(MIF) gene -173G/C and the susceptibility in patients with juvenile idiopathic arthritis(JIA).Methods Study group consisted of 97 children of JIA.All patients included in this study met the International League of Associations for Rheumatology criteria for JIA.Control group consisted of 102 healthy individuals.Germline DNA was extracted from peripheral blood by AxyPrep blood genomic DNA miniprep kit.Polymerase chain reaction-restrictivon fragment length polymorphism(PCR-RFLP) was used for genotyping the -173G/C polymorphism of MIF.Genotype distribution and allele frequencies were obtained by direct counting.Statistical analysis was performed by using SPSS Bosoftware.Allele and genotype distributions were compared using the chi-square test.The relative risk of alleles was described by odds ratios (OR) and 95% confidence intervals (95%CI).Hardy-weinberg equilibrium was confirmed with the chi-square test.Results We detected 3 kinds of genotypes at the MIF-173 locus.The frequency of each genotype was 54.6%(GG),42.3%(GC),3.1%(CC) in JIA group,and 79.4%(GG),20.6%(GC),0(CC) in control group.The C allele frequencies in the JIA and control group were 24.7% and 10.3%,respectively.There was significant difference was observed between the JIA and control group in the frequencies of mutant genotype(GC and CC) of MIF-173G/C polymorphism(?2=13.872 P=0).Individuals possessing a MIF-173C allele did have an increased risk of JIA(OR=2.79,95% CI 1.62-4.81 P=0).When the genotype and allele distributions of the MIF-173 gene in the subtypes of JIA and contronl group were compared,a significant difference wad found in the systemic JIA and control group (P0.05).Conclusions MIF-173G/C SNP may be associated with the sensitivity of JIA.MIF-173 C allele may increase susceptibility to JIA.

OBJECTIVEThis study described the clinical, surgical, and radiographic findings of simple bone cysts.

METHODSA retrospective study was conducted for patients diagnosed with simple bone cysts in the Department of Oral and Maxillofacial Surgery of the Affiliated Stomatological Hospital of Nanchang University from March 2005 to March 2015. Clinical, radio-graphic, surgical, and follow-up data were gathered. Results were statistically analyzed by central tendency and dispersionusing SPSS 20.0 software.

RESULTSEleven cases of simple bone cysts were collected, including three male and eight female patients. Ten cases (90.9%) were asymptomatic and one case developed symptoms of swelling. All of the cases had no history of trauma in the affected area, and all were solitary; ten cases (90.9%) were unilocular, and one (9.1%) was multilocular.The shape of each lesion could be assigned to four categories: cone (3 cases), round (2 cases), oval (4 cases), and irregular (2 cases). The treatment in 10 cases consisted of surgery to explore the cavity and curettage of the bone walls. During surgery,the bone cavity in seven cases (70%) was vacant, whereas serous fluid was found in two cases (20%) and serous-bloody fluid in one case (10%). Of the ten cases, three cases exhibited complete bone healing and seven cases showed new bone formation.

CONCLUSIONSimple bone cysts of the jaws are usually asymptomatic and appear incidentally on routine radiographies. The prevalence is higher in the mandible and young people. The patient usually has no history of trauma, and the bone cavity of lesion is mostly vacant. Curettage of the bone walls of the lesion is suggested for simple bone cysts. Systemic clinical and radiologic follow-up are necessary to ensure successful treatment.

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy. Spinal stereotactic radiosurgery and minimally invasive techniques, such as vertebro- plasty and kyphoplasty, percutaneous pedicle screw fixation, radiofrequency ablation are promising options for treatment of cer- tain selected patients with spinal metastases.

OBJECTIVETo explore the clinical significance of serum free light chain (sFLC) levels in nonsecretory multiple myeloma (NSMM).

METHODSNine NSMM patients were hospitalized in our department from Feb 2002 to Sep 2006 and no M-components was found in their serum and urine by immunofixation electrophoresis (IFE). sFLC was assayed by immuno-nephelometry. The clonality of sFLC was estimated by serum kappa:lambda sFLC ratio. Meanwhile, serum immunoglobulin, total kappa and lambda light chain level were also determined in these patients.

RESULTSIncreased serum concentrations of either kappa or lambda sFLC (and abnormal kappa/lambda ratios) were detected in 6 of 9 patients with NSMM although their serum immunoglobulin levels were not elevated and total kappa:lambda light chain ratios (1.32 - 2.20) were in the reference range. All the 9 patients had clonal IgH gene rearrangements.

CONCLUSIONQuantification of sFLC by immuno-nephelometry is more sensitive than that of serum total light chain measurement and is helpful in estimating the clonality of the light chain in patients with NSMM.

OBJECTIVETo analyze the clinical and laboratory features and risk factors of multiple myeloma (MM) with extramedullary disease (EM) and its extraosseous localizations at diagnosis and during the course of MM.

METHODSThe clinical features, survival rate and prognostic factors were retrospectively analyzed in 40 patients having EM from a total of 418 MM patients hospitalized in Changzheng Hospital from 1993 to 2006.

RESULTSAmong the 40 patients, the first three localizations of EM involved soft tissue, pleura or peritoneum and central nervous system (CNS). Median duration of follow-up was 30 months. The median overall survival (OS) was 28 months. Twenty-five patients (6%) were found to have EM at diagnosis (group A), and their median OS was 16 months and 15 patients (3.6%) developed EM during the course of the disease (group B), and their expected median OS was 72 months. There was a significant difference between group A and B (P = 0.0045) for OS. Compared with those in group A, patients in group B had a higher percentage of plasmacytes (P = 0.022) and plasmablasts (P = 0.029) in bone marrow, and less advanced stage for international staging system (ISS) (P = 0.027). Log-rank univariate analysis showed that higher CRP level, higher serum LDH, Stage II and III for ISS, Hb < 110 g/L at diagnosis were poor prognostic factors. However, multivariate analysis with COX model showed none of them were statistically significant.

CONCLUSIONEM tumors are not a rare manifestation of MM. Soft tissue in the commonest area involved. Higher serum CRP and LDH level, more advanced stage for ISS, anemia and having EM are poor prognostic factors of MM.

OBJECTIVETo express SPAG4L, a novel human testis gene in E. coli and purify it's fusion protein.

METHODSThe fragment encoding SPAG4L126-379 was amplified by RT-PCR and the PCR products were cloned into PUCm-T vectors. After digestion by EcoR I and Hind III, the fragment was subcloned into PQE-30, a prokaryotic expression vector with 6×His tag. The recombinant plasmid PQE-30-SPAG4L was sequenced and transformed into E.coli M15. The expression of his-tagged fusion protein was induced by IPTG. The fusion protein was identified by Western blotting and purified using Ni-NTA magnetic agarose beads.

RESULTSThe recombinant plasmid PQE-30-SPAG4L was constructed successfully and expressed in E.coli M15. The fusion protein SPAG4Lwith 6×his-tag was confirmed by Western blotting. The micro-scale purification system of 6×His-tagged SPAG4Lprotein was established and purified fusion protein was obtained.

CONCLUSIONThe recombinant plasmid PQE-30-SPAG4L can be expressed in vitro and used for studying the biological function of SPAG4L in spermatogenesis.

OBJECTIVETo explore the relationship of beta-catenin and sensitivity to Bortezomib of myeloma cell lines.

METHODSMyeloma cell lines RPMI8226, CZ-1 and NCI-H929 were treated with Bortezomib and 2ME2, alone or in combination. Typan blue dye exclusion and modified MTT were used to assess the cell viability with or without treatment. Annexin V-FITC and PI staining was performed to detect apoptosis rate. RT-PCR was used to detect beta-catenin mRNA and western blot to analyze beta-catenin protein.

RESULTSThe basic expression level of beta-catenin was different in tested myeloma cell lines: RPMI8226 was the most while NCI-H929 the least and CZ-1 the intermediate. IC50 of RPMI8226, CZ-1 and NCI-H929 were (49.8 +/- 0.6), (24.7 +/- 0.4) and (8.4 +/- 0.2) nmol/L, respectively. After the treatment of Bortezomib (at 0, 1, 5, 10 nmol/L), beta-catenin level of tested cell lines accumulated in a time and dose dependent manner for western blot, while no significant change was observed in the result of RT-PCR. The beta-catenin protein levels in the Bortezomib (5 nmol/L) and 2ME2 (1 micromol/L) treated cell group were much lower than that in Bortezomib (5 nmol/L) group, the decrease of the gray scale of beta-catenin/beta-actin was 64.03% for RPMI8226, 52.56% for CZ-1, 51.48% for NCI-H929, and the apoptosis rates were 8.00, 1.86 and 1.19 times increase compared to untreated group.

CONCLUSIONMyeloma cell lines with higher beta-catenin level are less sensitive to Bortezomib, and combination treatment of low dose 2ME2 and Bortezomib can reduce beta-catenin accumulation and enhance the sensitivity to Bortezomib.

OBJECTIVEThe exercise rehabilitation in patient with chronic heart failure (CHF) is standard clinical practice, but it is rare using CardioPulmonary Exercise Testing (CPET) guide to prescribe exercise rehabilitation in China.

METHODSWe performed symptom limited maximal CPET in 10 patients with CHF, randomly divided into two groups: 5 patients as control without exercise and 5 exercise patients used Δ50%W intensity to exercise 30 min/d, 5 d/w, x12 w. Before and after 12 w rehabilitation, we evaluated functions.

RESULTSThere were no significant difference between two groups patients (P > 0.05). The exercise duration was increased from 8 min to 23 min after rehabilitation (P < 0.001); distance 6 minutes walking was increased from 394 m to 470 m (P < 0.05); score of Minnesota quality of life was decreased from 25 to 3 in exercise group (P < 0.01). However, there were nosignificant changes in control group (P>0.05) and their changes were smaller than those in exercise group (P < 0.01).

CONCLUSIONThe CPET guiding exercise rehabilitation is safe and effective for patients with CHF.
