Osteopontin is a part of cell wall, which plays an important role in adherence, migration of cell, repair of tissue. Nearly studies suggest that there are relationship between osteopontin and arthritis.

Objective To explore the efficacy of retroperitoneal laparoscopy in the treatment of parapelvic cyst.Methods From August 2005 to December 2008,16 cases of parapelvic cyst were treated by retroperitoneal laparoscopic deroofing and decompressing in our hospital.Under general anaesthesia,an operational space was established via retroperitoneal route.And then,along the urethra,the parapelvic cyst was explored.Afterwards,the cyst was unroofed 3 to 5 mm from the normal renal tissues.Results The operation was completed in 15 of the patients with a mean operation time of(75?20) minutes and mean blood loss of(28?8) ml.No injuries to the kidney pedicle or pelvis occurred.Another patient was converted to open surgery because of difficulty in exposure of the cyst.This series were followed up for a mean of 13 months(range,6 to 20 months).No one had recurrence during the period.Conclusions Retroperitoneal laparoscopic deroofing is minimally invasive,safe and effective or parapelvic cyst.It should be the first choice for the disease.

OBJECTIVE:To observe the curative effect of tazobactam sodium/piperacillin sodium for injection on the Neonatal infections.METHODS:140neonatal infections cases were randomly divided into treatment group and control group:the treated group were treated with tazobactam sodium/piperacillin sodium for injection100～200mg/(kg?d);while the con?trol group were treated with penicillin-G100000～200000IU/(kg?d).The course of therapy for both groups were5d～10d.RESULTS:The effective rates of the treatment group and the control group were91.43%,52.86%(P

Objective To explore the characteristics of hematological changes in patients with primary Sj(o)gren'syndrome (pSS).Methods The clinical data of 49 cases with pSS were retrospectively analyzed.Resuits The data showed that 25 patients (51%) among 49 cases had hematological changes.of which 15 cases were anaemia (31%).8(16%) were leukopenia,and 10 cases (20%) were thrombocytopenia.And 6 cases had two cell lines involved.2 cases had three cell lines involved.Twenty-three bone marrow aspirations revealed active proliferation or normal cell proliferation and the morphology of all 3 cells lines were normal.Bone marrow examination had strong positive iton stain and 15 cases with anaemia showed positive iron stain.Seven out of 10 patients with thrombocytopenia had megakaryocyte maturation defect.Conclusion Hemotologieal changes are common.and anemia is the most common findings.Cytopenia is related to autoantibodies mediated stem cell damages.but anemia iS caused by iron metabolic disturbance.while thrombocytopenia is generally due to functional impairment of megakaryocytes.

Objective To study the effect of various methods determining lung volume and fraction dose on the lung dose-volume parameters for lung cancer patients. Methods Twenty patients with lung cancer were rantdomly enrolled into our study and the plan of three dimensional eonformal radiation therapy(3DCRT)was designed by Varian Eclipse TPS.The lung volumes and the dose-volume parameters were measured under CT value of-300- -980, -400- -980 and -500- -980.Under CT value of -400- -980,total lung volumes were confirmed.The dose-volume parameters of V30,V20,V10 and mean lung dose(MLD)were reevaluated after GTV,CTV and PTV were subtracted from the total lung volumes and when the fraction dose was elevated from 2.0 Gy to 10.0 Gy. Results When the CT value ranged from-300--980 to-500--980,the median reduction of the total lung volumes(-9.10%)was significantly higher than that of V30,V20,V10 and MLD(-3.18%,-1.13%,0.82%and-0.79%,respectively).When the total lung volume was fixed at CT value of-400--980,the alterations of V30,V20,V10 and MLD became more apparent as the increase of the subtracted lung volume,among which the alteration of V30 was most significant while V10 the least.Among five cases with a fixed total dose of 60 Gy and PTV less than 140 cm3,the V30,V20,V10 and MLD were increased to a similar extent(about 40%)when the fraction dose was increased from 2.0 Gy to 10.0 Gy.MLD was increased(36%)when the fraction dose was above 6.0 Gy. Conclusions When CT value ranges from-300- -980 to-500- -980,the total lung volume is influenced most.The alteration of V30,being statistically significant,might have some significance but is not enough to determine the plan of radiotherapy clinically.The alteration of V20、V10 and MLD is not statistically significant.When the overlapped target volume is subtracted from the total lung volumes,the alteration of V30 is the most sign:tifhcant while V10 the least.The fraction dose,being the most consuming factor(＞10%)when comparing with the CT valHe and targeted volume,can significantly influence the dose-volume parameter.

Objective To investigate the single nucleotide polymorphisms(SNPs) rs3733591(C>T) of SLC2A9 gene in Chinese Han population, and to explore the association of this gene polymorphisms with gout susceptibility, tophi, serum uric acid levels, other clinical and laboratory data and the levels of SLC2A9 mRNA of peripheral blood mononuclear cells(PBMCs). Methods ① A total of 297 primary gout arthritis patients(GA) and 211 normal controls(NC) were enrolled into this study. The clinical and laboratory data of patients were collected. The genotypes and alleles frequencies were measured by using TaqMan ?SNP Geno-typing Assays and the possible association between gene polymorphism of SLC2A9 and gout was investigated by Chi-square test. The odds ratios(OR) and 95% confidence intervals(95%CI) were calculated. ② The lev-els of SLC2A9 mRNA on PBMCs of 86 gout patients(46 patients in remission) and controls were measured by real-time quantitative polymerase chain reaction (RT-qPCR). The nonparametric test was used to analyze the expression in different groups. Results The frequencies of genotypes and alleles of rs3733591(C>T) in gout patients were different from controls(P<0.05). The frequency of TT genotype was significantly lower than that in controls (P<0.05) and the relative risk of this genotype to develop gout was 0.647 (95%CI: 0.452-0.925). Moreover, the frequency of T allele in cases was much lower than in controls (60.9% vs 69.2%, χ2=7.324, P=0.007, OR=0.695), but the frequency of C allele was much higher(39.1% vs 30.8%, χ2=1.440, P=0.007, OR=1.440). Interestingly, the levels of SLC2A9 mRNA on PBMCs in gout patients who carried TC genotype of rs3733591 was higher than those who carried TT genotype(P<0.05). There was no difference in the expression of SLC2A9 mRNA on PBMCs among different genotype carriers of rs3733591 in controls (P>0.05). However, there was no significant difference in the distribution of genotypes and alleles between 30 tophaceous gout patients and 190 non-tophaceous gout patients(P>0.05). Conclusion Results of present study suggest the rs3733591(C>T) polymorphism of the SLC2A9 gene might be associated with gout development, but not with tophaceous gout. The C allele predisposes to gout, and TT genotype and T allele might protect Chinese Han population from developing gout. The rs3733591(C>T) polymorphism probably affects the susceptibility to gout by influencing the f expression of SLC2A9 mRNA susceptibility.

Objective To evaluate the change of left ventricular diastolic function and investigate the relation between left ventricular diastolic function and disease activity in rheumatoid arthritis (RA) without clinical manifestations of heart diseases. Methods Seventy consecutive active RA in-patients without clinical manifestations of heart disease were enrolled, while the control group was recruited from outpatient health physical check-up center and consisted of 60 age- and sex-matched healthy subjects. Cardiac related parame-ters were determined by echocardiography and the correlation between left ventricular diastolic function and the disease activity indexes were evaluated. Chi-square test, t test, Pearson or Spearman′s correlation test and Stepwise backward linear regression analysis were used for statistical analysis. Results RA patients had lower mitral inflow E/A ratio (1.2±0.4, 1.5±0.4, P<0.01), higher E/Em ratio (9.6±3.7, 7.8±2.0, P<0.01), longer isovolumetric relaxation time(IVRT)[(64±16) ms,(58±16) ms, P<0.05] than control group. Whilst, RA patients had higher pulmonary venous inflow A wave velocity-time integral (ArVTI) and A wave duration (DAr)[3.2±0.7,(2.8±0.6) cm; 117±11,(102±9) ms, P<0.05]. Moreover, the E/Em was positively corre-lated with C-reactive protein(CRP)(r=0.581, P<0.01), DAS28(r=0.456, P<0.01). Anti-CCP level was also associated with Em and early diastolic pulmonary venous inflow peak velocity(PVD)(r=-0.359, P<0.05;r=-0.305, P<0.05). In addition, multivariate analysis also revealed that there was linear regression relation-ship between E/Em and CRP, DAS28(t=3.266, P=0.002; t=2.949, P=0.005). Conclusion The study has revealed that left ventricular diastolic function is impaired in RA patients and the left ventricular diastolic function parameters is associated with the disease activity indexes. These results suggest that the decline of left ventricular diastolic function is associated with the inflammation activity in RA patients without clinical manifestations of heart disease.

ObjectiveTo study the curative effect of early intervention on selective head sub-hypothermia in full term infant with severe asphyxia.MethodsForty two full term infant with severe asphyxia were randomly divided into treatment(n =22) and control ( n =20) group,all patients were treated according to three supportive therapy and three heteropathy after resuscitation,and meanwhile the treament group combined with selective head sub-hypothermia.In the 2 groups,heart and breath oxygen saturation,blood sugar were measurded within 72 hours after treatment,and the Chinese 20-item neonate nerve behaviors were evaluated 28 days after birth.Test were conducted with the Bayley infant development scale in 2 months after birth.ResultsAfter 72 hours of treatment,the heart rate of treatment group reduced and showed significant difference from that of contol group and restored to normal.There were no significant differences in breath,blood pressure(BP),degree of blood ozygen saturation,blood sugar between the 2 groups.After 28 days of birth,scores of neonate nerve behaviors were ( 37 ± 3) in treatment group and (31 ± 3) in control group,respectively ;which showed significant difference ( P ＜ 0.01 ).In the 2nd months of birth,scores of Bayley infant development scale were (91 ± 3 ) in treatment group and ( 86 ± 4 ) in control group,respectively,which showed significant difference(P ＜ 0.05 ).ConclusionSelective head sub-hypothermia was convenient and safe,and had reliable curative effect by relieving or prenventing sequel and raising quality of life.

Objective To investigate the role of adiponectin (ADP) and its receptors (ADR) in pati ents with primary gouty arthritis (GA).Methods Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of plasma ADP in 88 GA and 80 healthy controls (NC).Real time quantitative polymerase chain reaction (RT-qPCR) was employed to study the expression of ADR1 and ADR2 mRNA in peripheral blood mononuclear cells (PBMCs).The biochemical indicator of TG,HDL,LDL,VLDL,apoA1,apoB100 and uric acid (UA) were detected at the same time.T test,Spearman's correlations and regression analysis were used for statistical analysis.Results The concentration of plasma ADP was significantly lower in GA than that in NC [(6±7) μg/ml,(8±6) μg/ml,t=-3.71,P＜0.01 ],the expression of ADR1 and ADR2 mRNA in GA (ADR1:0.09±0.08,ADR2:0.0122±0.0164) was significantly increased when compared to the NC (ADR1:0.05±0.03,ADR2:0.0054±0.0024) (t=2.71,2.35,P＜0.05).In the GA patients,the level of ADP was negatively correlated with the lymphocytes count (LY) and UA (r=-0.32,-0.36,P＜0.05),and it was positively correlated with ESR and LDL level (r=0.31,0.39,P＜0.05).The expression of ADR1 mRNAwas negatively correlated with TG (r=-0.43,P＜0.05 ),but positivdy correlated with ESR and CRP level (r=0.45,0.57,P＜0.05).The expression of ADR2 mRNA was negatively correlated with glucose and UA(r=-0.50,-0.59,P＜0.05).Conclusion Altered expression of ADP and its receptors may be involved in thepathogenesis of gouty inflammation.
