Object To investigate the relationship between plasma tumor necrosis factor ?(TNF-?) and insulin resistance in the patients with non obese type 2 diabetes.Methods The levels of plasma TNF-? and serum insulin were measured in 38 patients with type 2 diabetes and 30 healthy subjects by immuno-radioassay. Insulin sensitive index (ISI) and body mass index(BMI) were also calculated. The correlation analysis was done between TNF-? and ISI.Results ⑴ The levels of plasma TNF-? in type 2 diabetes were 30 79?6 64fmol/ml, and higher than those in controls (P

Objective To analyze the histological changes of bone diseases and to investigate the noninvasive measurements for diagnosing renal osteodystrophy (ROD) in maintenance dialysis patients . Methods Ninety-one patients were selected to receive bone biopsy . The bone samples were stained with HE, toluidine blue and Masson, and were examined with light microscopy . The levels of immunoreactive parathyroid hormone (iPTH), osteoprotegerin (OPG),sRANKL and osteocalcin (OCN) were determined in the patients enrolled from 2004 to 2006 . The level of iPTH was measured by radioimmunoassay . OPG and sRANKL were measured by ELISA,and OCN was measured by chemiluminescence . Results The incidence of ROD in the maintenance patients was 100% . According to the histological appearance, 50 cases (54 .9%) were high turnover bone disease (secondary hyperparathyroid bone disease), 9 cases (9 .9%) were low turnover bone diseases(osteomalacia and adynamic bone disease), and 32 cases(35 .2% ) were mixed bone disease . The level of iPTH in patients with ROD was significantly increased compared with healthy controls . It was the lowest in low turnover bone diseases . There was no difference among three types of ROD . OPG level was significantly increased compared with healthy controls [(2176 .58±1576 .08) pmol/L vs (1310 .46±1254 .00) pmol/L, P<0 .05] . The level in high turnover bone diseases was higher than that of the healthy controls [(2261 .85±1712 .22) pmol/L vs (1310 .46±1254 .00) pmol/L, P<0 .05] . There was no difference among three types of ROD .sRANKL level in high turnover bone disease was significantly increased compared with healthy controls [(0 .328±0 .524)pmol/L vs (0 .084±0 .190) pmol/L, P<0 .05] . OCN level was also higher than that of the healthy controls (P<0 .05), and the OCN level in low turnover ROD was the lowest among three types of ROD . OCN level in mixed ROD was dramatically increased as compared to low turnover ROD [(226 .633±66 .455) pmol/L vs (193 .03±104 .269) pmol/L, P <0 .05] .Conclusions The histological changes of bone disease can be indicated by iPTH level, but the types of ROD can not be distinguished according to iPTH level neither be differentiated by the levels of OPG, sRANKL and OCN . Bone histomorphometry is still the golden standard for diagnosing renal osteodystrophy .

Objective To study the brain protection of sequential double-sided antegrade cerebral perfusion to central nervous system in arotie arch surgery. Methods 24 patients received aortic arch replacement under deep hyperthermic circulatory arrest (DHCA) ,with fight-sided, and following double-sided, and left-sided,if necessary, antagrade cerebral perfnsion through right axillary arterial cannula or right femoral arterial eannula homeochronously. Post-operation recovery and the central nervous complications (CNC) were recorded and analyzed. Results 2 cases died, one of whom died of refractory low cardiac output syndrome and the other died of late massive gastrointestinal tract hemorrhage. No patient suffered severe CNC. Conclusion Sequential double-sided antegrade cerebral perfusion combined with DHCA can provide good brain protection in arotic arch replacement.

Objective To explore the prevalence of sialorrhea and its clinical correlation with dysphagia in Chinese patients with Parkinson′s disease ( PD ).Methods One hundred and sixteen consecutive patients with a clinical diagnosis of PD were selected.Demographic data included sex , age, years of education, age at onset of PD, clinical genotype, disease duration, treatment, Hoehn and Yahr (H&Y) stage.Sialorrhea was assessed using the Unified Parkinson′s Disease Rating Scale (UPDRS) Ⅱitem number 6.All patients were studied with videofluoroscopic study of swallowing ( VFSS).Results The prevalence rate of sialorrhea in PD was 59.5% (69/116, 95% CI 50.6%-68.4%).Males were more likely to develop sialorrhea than females (47/70 vs 22/46,χ2 =4.298, P=0.038).PD patients′sialorrhea correlated with oral dysphagia:with food leaking from the mouth ( liquid r=0.229, P=0.014; juice r=0.197, P=0.034;pudding viscosities r=0.231, P=0.013;solid food r=0.255, P=0.006), with more than 1 ml of oral food residues (liquid r=0.319, P<0.01;solid food r=0.185, P=0.047), with delay in food transfer to the root of the tongue (liquid r=0.279, P=0.002; juice r=0.209, P=0.024), and delayed swallow transfer ( pudding viscosities r=0.257, P=0.005).Sialorrhea score was not related to H&Y stage, clinical course and levodopa equivalent doses (LED).The prevalence rate of dysphagia in PD was 87.1%(95% CI 81.0% -93.2%).Liquid was more likely to cause pharyngeal dysphagia ( P=0.03).With the increase in H&Y stage , so did the oral and pharyngeal stages of dysphagia.Late and mid-course was more likely to develop oral and pharyngeal dysphagia than those with early clinical course .Conclusions Sialorrhea and dysphagia are common non-motor symptoms in PD patients.Sialorrhea is more prevalent in males and correlates with oral phase of dysphagia.Liquid is more likely to cause pharyngeal dysphagia.With increase in H&Y stage , so did oral and pharyngeal dysphagia.Even though late clinical course is more likely to develop oral and pharyngeal dysphagia than early clinical course , the comparison between late and intermediate clinical courses does not reach statistical significance .

OBJECTIVE:
To explore the genetic basis for a Chinese pedigree where three siblings were affected with Parkinson's disease.
METHODS:
Multiple ligation-dependent probe amplification (MLPA) and next-generation sequencing (NGS) were employed to detect the causative mutation. Sanger sequencing of cDNA was also used for verify the effect of mutation on the transcription of RNA.
RESULTS:
Heterozygous deletion of exon 3 of the PARK2 gene was detected by MLPA, while a heterozygous splice site variant c.619-3G>C was detected by NGS. Both mutations were shown to result in aberrant transcripts of the PARK2 gene (loss of exons 3 and 6, respectively) by Sanger sequencing of cDNA. Both mutations have co-segregated with the disease in the pedigree.
CONCLUSION
Compound heterozygous mutations of the PARK2 gene probably underlie the disease in this pedigree. Identification of the splice site variant c.619-3G>C has expanded the mutation spectrum of the PARK2 gene.

OBJECTIVE:
To explore the genetic basis of a patient with early-onset Parkinson disease from a consanguineous family.
METHODS:
Homozygosity mapping and Sanger sequencing of cDNA were used to identify the causative mutation.
RESULTS:
A homozygous missense variation (c.56C>G, p.Thr19Arg) in the PARK7 gene was identified in the patient. In silico analysis suggested the c.56C>G variation to be pathogenic.
CONCLUSION
Homozygous c.56C>G variation of the PARK7 gene was the disease-causing variation in this family.
