Objective To assess if evaluating with Peabody's fine motor development scale with 4 degree grading is more sensitive than with 3 degree grading, and whether or not it is feasible to evaluate by quantization with monthly averages. Methods A total of 864 normal children aged 1 month to 60 months were evaluated with the Peabody scale using 4 degree grading and 3 degree grading. The development results were averaged by month to express the development. Results Both ways, the monthly averages of children 4-9 months old were higher than the others. The values obtained with 4 degree grading were lower than those with 3 degree grading in each functional area, and the difference was more obvious with increasing age, but the differences were not statistically significant. With 3 degree grading the total score was equal to the actual score after the age of 9 months, but with 4 degree grading this was not true until at least 18 months. Conclusions Evaluating with Peabody's fine motor scale with 4 degree grading and quantization using monthly averages is reliable and more sensitive than 3 degree grading.

Objective To evaluate the functional magnetic resonance (MR) imaging in the assessment of renal involvement and pathological changes in patients with lupus nephritis (LN).Methods Seventeen patients with LN and 10 healthy controls underwent coronal echo-planar diffusion-weighted (DW) MR imaging and blood oxygen level dependent (BOLD) MR imaging of the kidneys with a single breath-hold time of 16 s.The apparent diffusion coefficient (ADC) and R2* value of the kidneys were calculated with high b values (b=500 s/mm2).The correlation between the renal injury variables and the ADCs or R2* values was evaluated.Results The mean ADC value of kidneys in patients with LN was (2.43+0.24)×10-3 mm2/s,the mean R2* values of the renal cortex and medulla were (11.72+2.35)/s and (13.07+2.35)/s respectively,which were all significantly lower than those in volunteers (P=0.045,P=0.048and P=0.001,respectively).In the patients with LN,the mean ADC values were positively correlated with estimated glomerular filtration rate (eGFR) (r=0.558,P＜0.05).There was a negative correlation between the ADC values of the right kidneys and pathological chronic indexes (r=-0.493,P＜0.05).Moreover,the R2*values of the renal medulla were negatively correlated with 24 hours proteinuria,serum creatinine,pathological active indexes.The patients were assigned to group A (class Ⅲ,Ⅳ,Ⅴ,n=8) and group B class Ⅴ + Ⅲ and Ⅴ + Ⅳ,n=9).The tubulointerstitial lesions in group B were more severe than those in group A,while the mean ADC values and R2* values of the renal cortex in group B were lower as compared to group A.Conclusion DW MR imaging and BOLD MR imaging may be used to non-invasively monitor the disease activity and evaluate the efficacy in lupus nephritis.

Objective To investigate the utility of diffusion weighted imaging (DWI) and blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI) in the assessment of renal hypoxia in an experimental model of mice with lupus nephritis (LN).Methods MRL/lpr mice (n=13) were studied and C57BL/6 mice (n=10) served as controls.Urinary albumin to creatinine ratio (ACR),serum creatinine (Scr),anti-ds-DNA antibody,and complement C3 levels were measured.The mice underwent coronal echo-planar DWI and BOLD MRI of the kidneys when they were 14-16 weeks old.Hypoxyprobe was administered intraperitoneally to the mice 1 hour before they were sacrificed.The distribution of HypoxyprobeTM-1,hypoxia-inducible factor 1 α (HIF-1 o) and heme oxygenase-1 (HO-1) in renal tissues was detected by immunohistochemical analysis and Western blotting.Results Urinary ACR,Scr and anti-ds-DNA antibody levels in MRL/lpr mice were significantly higher than that in C57BL/6 mice.It was found that HypoxyprobeTM-1,HIF-1o and HO-1 distributed widely in the renal tissue of MRL/lpr mice,and closely associated with the renal tubulointerstitial lesion.The mean apparent diffusion coefficient (ADC) value of kidneys in MRL/lpr mice was (1.52±0.27) × 10-3 mm2/s,and the mean R2* values of the renal cortex and medulla were (30.95 ±4.59)/s and (23.43± 3.06)/s respectively,all significantly lower than that in C57BL/6 mice (P=0.037,P=0.030 and P=0.043,respectively).The ADC of medulla was negatively correlated with urinary albumin to creatinine ratio (r=-0.364,P=0.032;r=-0.329,P=0.050),the ADC of cortex was negatively correlated with the level of serum creatinine (r=-0.814,P=0.014;r=-0.755,P=0.031) when b value was 500 s/mm2 and 800 s/mm2,and the mean R2* value was negatively correlated with the degree of tubulointerstitial lesions and the expression of hypoxia parameters (all P ＜ 0.05).Conclusions Renal hypoxia may play an important role in renal tubulointerstitial lesion.Functional MRI may be used to monitor renal function changes,pathological injuries and renal hypoxia in LN.

AIM:To investigate the effect of compound of cordyceps sinensis(CS) and tripterygium hypoglaucum on survival time of the heterologous human-pig graft skin.METHODS: CS solution were used to hatch the skin graft and CS was used locally.Ciclosporin A(CsA) and normal saline solution(NS) were used in control.Besides,skin HE staining was detected and CD4,CD8,IL-2 and IL-10 were also examined before and after operation.RESULTS: The survival time of the graft skin treated with CS was(21.20?3.19) days,while the control group treated with NS was(10.17?1.94) days(P

AIM: To detect the association between the polymorphism of Fc receptor ? chain gene at position-29 in promoter and systemic lupus erythematosus(SLE). METHODS: The genotypes at position -29 in promoter of Fc receptor ? chain gene were determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 180 patients with SLE and 140 ethnically matched controls in southern China. RESULTS: The frequencies of TT genotype(33.3%) and T allele (54 4%) at position -29 in patients with SLE were significantly higher than those in controls (17 9%, respectively), whereas, the frequencies of GG genotype (24 4%) and G allele (45 6%) in patients with SLE were remarkably lower than those in controls (31 4% and 57 1%, respectively) ( P 0 05) . CONCLUSION: Our results indicate that the T allele at position -29 in promoter of Fc receptor gene probably contributes to the susceptibility to SLE, but does not play a role in the occurrence of lupus nephritis.

Objective:To systematically evaluate the effects of low protein diet combined with α-keto acid on calcium and phosphorus metabolism and nutritional status in patients undergoing hemodialysis.Method:Randomized controlled Trials were searched in Cochrane Library, Web of Science, PubMed, Embase, CBM, CNKI, Wanfang and VIP databases from the establishment of respective database until July 2021, and meta-analysis is conducted using RevMan 5.4.Results:A total of 8 studies including 556 patients were selected. Meta-analysis showed that after receiving low protein diet combined with α-keto acid, patients demonstrated significantly reduced blood phosphorus [MD = -0.17, 95% CI (-0.25, -0.7), P < 0.01], calcium- phosphorus product [MD = -6.17, 95% CI (-6.67, -5.58), P < 0.01] and parathyroid hormone levels [MD = -35.36, 95% CI (-40.89, -29.83), P < 0.01]. There was no significant difference in serum calcium [MD = 0.03, 95% CI (-0.00, 0.07), P = 0.08] and serum albumin [MD = 0.41, 95% CI (-0.12, 0.95), P = 0.13]. Conclusion:Low protein diet combined with α-keto acid can reduce the levels of serum phosphorus, calcium-phosphorus product and parathyroid hormone in hemodialysis patients while the effects on serum calcium and serum albumin are undetermined and need further verification.

A 1 270 bp full-length cDNA fragment was obtained from the Schistosoma japonicum (Chinese strain) adult cDNA library after the 3′ and 5′ ends of the incomplete expression sequence tag (EST) of hypoxanthine-guanine phosphoribosyltransferase of Schistosoma japonicum (SjHGPRT) were amplified by the anchored PCR with 2 pairs of primer that were designed according to the published incomplete SjHGPRT EST and the sequence of multiclone sites of library ?gt11 vector. Sequence analysis indicated that this fragment, with an identity of 82% to hypoxanthine-guanine phosphoribosyltransferase of Schistosoma mansoni (SmHGPRT), contained a complete open reading frame(ORF). The deduced amino acid sequence showed 83% identity to that of SmHGPRT. This fragment was cloned into the prokaryotic expression vector pQE30, and subsequently sequenced and expressed in Escherichia coli. SDS-PAGE revealed that M of the recombinant protein was about 28 ku. Western-blot analysis showed that the recombinant protein was recognized by the polyclonal antisera from rabbits immunized with Schistosoma japonicum adult worm antigen. Mice vaccinated with recombinant protein revealed significant worm burden, liver eggs per gram (LEPG), fecal eggs per gram (FEPG) and intrauterine eggs of the female worms reduction percentage, compared with the controls. Taken together, the SjHGPRT full-length cDNA can be cloned and expressed in E.coli as a recombinant protein that elicited immunity against the challenge infection with Schistosoma japonicum, indicating its potential as a partial protection vaccine candidate.
