A summary is made from the six aspects.

Objeetive To analyze the clinical significance of serial microproteinuria and urease detection in early diagnosis of antibiotics damage to kidney by observing the changes of urine microalbumin/creatinine ratio (mAlb/Cr),transferrin (TRF),IgG,α1-microglobulin (α1-M G),β2-microglobulin (β2-M G),retinol-binding pmtein(RBP) and N-acetyl-β-D-glucosaminidase(NAG).Methods A total of 161 children with pneumonia whose test results were normal of urine protein,blood urea nitrogen (BUN) and serum creatinine (Scr),and had no related history of kidney diseases were selected.All the patients were divided into three groups according to antibiotics for the treatment,the penicillins (penicillin G,amoxicillin and potassium clavulanate,ticarcillin and potassium clavulanate) group,the cephalosporins (cefazolin,cefuroxime,ceftriaxone,cefoperazone,ceftazidime) group and the macrolides (erythromycin,azithromycin) group.Changes of mAlb/Cr,TRF,IgG,α1-MG,β2-MG,RBP,NAG,BUN,Scr levels of the patients one week before and after use the antibiotics were observed,and statistically analyzed.Results In the penicillins group and macrolides group,the results showed that none of the serial microproteinuria and urease changed(all P ＞ 0.05).In the cephalosporins group,the urine mAlb/Cr,TRF,β2-MG and NAG were higher than before using the antibiotics [(15.56 ± 5.98) mg/g vs.(21.08 ± 10.88) mg/g,(1.61 ± 0,14)mg/L vs.(1.66 ±0.14) mg/L,(0.25 ±0.09)mg/L vs.(0.28 ±0.11)mg/L,(4.62 ±3.80) U/L vs.(4.98 ±3.97) U/L,t =-5.11,-3.24,-2.29,-2.04,P ＜ 0.05 ～ 0.001].The levels of BUN and Scr revealed no change in all the patients(all P ＞ 0.05).Conclusion Combined detection of serial microproteinuria and urease has great clinical significance in judgment and warning of early renal damage by antibiotics.

AIM: To explore the effect of physcion (P) on the level of IL-1? and expression of ICAM-1 and caspase-3 during cerebral ischemia-reperfusion injury. METHODS: The 91 healthy adult SD rats were selected, and were randomly divided into normal group, sham-operated group, cerebral ischemia-reperfusion group (model), low-dose physcion (PLD) and high-dose physcion (PHD) treatment group. The level of IL-1? was detected by radioimmunoassay. The expression of ICAM-1 and caspase-3 was detected by immunohistochemistry. The changes of tissue pathology were also investigated. RESULTS: The level of IL-1? reached the peak at 6 h after ischemia-reperfusion (IR). The protein expression of ICAM-1 and caspase-3 reached the peak at 24 h after IR. The level of IL-1? and the protein expression of ICAM-1 and caspase-3 in PHD group decreased obviously compared with those in model group (P

Objective To determine the value of acute phase protein in the early diagnosis of recurrence after curative gastric cancer surgery. Methods Acute phase serum protein level was measured before and after the gastric cancer surgery in 120 patients,and was compared with that of the control group. At 1, 3, 6, 9, 12 months after the operation in 87 patients undergoing curative gastric cancer surgery, the levels of acute phase proteins were measured. They were followed up for at least 12 months or until death. Results The levels of serum C reactive protein(CRP), ?1 antitrypsin (?1 AT) and ? acid glycoprotein (? AG) in gastric cancer group were significantly higher than those in the control group (P0.05). In patients who underwent curative gastric cancer surgery in a certain period after the operation, the serum levels of CRP, ?1 AT and ? AG were significantly lower than those before the surgery(P0.05).There were significant difference in CRP,?1 AT and ? AG between the recurrence groups and nonrecurrence group before and after the operation (P

OBJECTIVE: To analyze the clinical presentation and gene of 2 pedigrees with suspected oculocutaneous albinism(OCA), and provide basis for clinical classification, genetic counseling and prenatal diagnosis. METHODS: Variants were identified using next-generation sequencing(NGS) and confirmed by Sanger sequencing in 2 pedigrees with suspected OCA. The pathogenicity of the variants was analyzed according to the American College of Medical Genetics and Genomics (ACMG) standard. RESULTS: Two compound heterozygous mutations of TYR and OCA2 genes were identified respectively in 2 pedigrees with suspected OCA. The mutation of c.819+3insATATGCC in TYR and the mutation of c.1870G>C in OCA2 are first reported in this study. The pathogenicity analysis shows that two novel mutations are likely pathogenic by combination of prediction of SIFT, Polyphen-2 and Human Splicing Finder. CONCLUSION The findings of this study expand the mutational spectrum of OCA. Compound heterozygous mutations in the TYR and OCA2 gene may be responsible for clinical manifestations of 2 pedigrees with suspected OCA.

Objective: To assess the use of statins and low-density lipoprotein cholesterol (LDL-C) levels at admission in hospitalized patients aged 75 years and older with acute coronary syndrome (ACS) in China. Methods: Data used in this study derived from the Improving Care for Cardiovascular Disease in China (CCC)-ACS project, a nationwide registry with 150 tertiary hospitals reporting details of clinical information of ACS patients. This study enrolled patients 75 years and older with ACS in CCC-ACS project from November 2014 to June 2017. Patients were divided into two groups according to the history of atherosclerotic cardiovascular disease (ASCVD). Pre-hospital statin use, LDL-C levels at admission and prescription of statins at discharge were reported. Results: A total of 10 899 patients 75 years and older with ACS were enrolled. The median age was 79 years and 58.7% (6 397 cases) were male. Among patients with history of ASCVD, 33.9% (1 028 cases) of them received statins before hospitalization. Among patients without history of ASCVD, 12.7% (996/7 871) received statins before hospitalization. The mean level of LDL-C was (2.4±0.9) mmol/L and LDL-C was <1.8 mmol/L in 24.7% (747 cases) of patients with history of ASCVD. The mean level of LDL-C was (2.6±0.9) mmol/L and LDL-C was <2.6 mmol/L in 51.7% (4 072 cases) of patients without history of ASCVD. At discharge, 91.2% (9 524/10 488) of patients were prescribed with statins in patients without contraindications for statin. Conclusion In elderly patients with recurrent ASCVD, there was an inadequate statin use before hospitalization and most patients did not reach the LDL-C target level when they had the recurrent events. In the elderly ACS patients without history of ASCVD, more than half of the patients had an ideal LDL-C level. It seems that ideal LDL-C level for primary prevention of ACS in elderly people needs to be reevaluated with further studies.

Objective:To assess the predictive performance of the risk of cardiovascular diseases (CVD) derived from the China Kadoorie Biobank (CKB-CVD) model, prediction for atherosclerotic cardiovascular disease (ASCVD) risk in China (China-PAR) model, and the risk of fatal and nonfatal ischemic cardiovascular diseases derived from the USA-People′s Republic of China Collaborative Study (USA-PRC) model in Chinese Multi-provincial Cohort Study (CMCS).Methods:In this prospective cohort study, a total of 21 948 individuals aged ≥35 years without CVD were selected from 8 provinces and cities in China during the CMCS survey from 1992 to 2005 for 10-year follow-up. The occurrence of CVD or ASCVD events during the follow-up period was used as the gold standard. The CKB-CVD and China-PAR models were used to calculate the predicted risk of CVD events, while the USA-PRC model was used to calculate the predicted risk of ASCVD events. The discrimination of the models was evaluated using the C-statistic, and the calibration was assessed using the Hosmer-Lemeshow χ2 test and decile plot. Results:During the 10-year follow-up, a total of 955 (4.4%) CVD events, including 791 (3.6%) ASCVD events, were recorded among the study participants. The C-index for the CKB-CVD, China-PAR, and USA-PRC models were 0.775 (95% CI: 0.757-0.793), 0.781 (95% CI: 0.763-0.798), and 0.769 (95% CI: 0.750-0.789) for men, and 0.762 (95% CI: 0.737-0.788), 0.769 (95% CI: 0.745-0.794), and 0.767 (95% CI: 0.741-0.794) for women, respectively. China-PAR model showed good calibration for men ( χ2=2.20), however, both CKB-CVD and USA-PRC models demonstrated poor calibration in both men and women ( χ2>20). The results indicated that the CKB-CVD model overestimated the risk of CVD events in both males and females, while the China-PAR model underestimated the risk in females. Furthermore, the USA-PRC model underestimated the risk of ASCVD in both males and females in most decile groups, but overestimated the risk in the highest decile group. Conclusion:The CKB-CVD, China-PAR, and USA-PRC risk assessment models show some degree of deviation from the actual risk of events in the CMCS cohort, but all exhibit good discrimination.

Objective To explore the pathogenesis of Russell-Silver syndrome (RSS). Methods Two milliliter peripheral blood samples were collected from 6 male patients aged 6 to 8 years with suspected RSS phenotype, the parents of 2 patients and 5 healthy boys. Mononuclear cells were isolated and genomic DNA was extracted. The methylation level of the H19 imprinting control region(ICR)1 on chromosome 11p15.5 was detected by pyrosequencing.The methylation status and the copy number variation in the corresponding region of one RSS patient with positive results by pyrosequencing were analysed by methylation-specific multiplex-ligation-dependent probe amplification assay (MS-MLPA). Results Pyrosequencing analysis revealed that the methylation rates on the 6 CpG targeting sites in H19 differentially methylated region(DMR)in the 6 RSS patients were about 11%~29%, which were significantly lower than those in their parents and normal controls (44%~59%). The MS-MLPA results of one patient with positive pyrosequencing showed that the methylation rates of 4 sites in H19-DMR were about 10%,which was obviously lower than the normal level.The methylation rates of the 4 sites in KCNQ1OT1 gene were about 50%, which was in the normal range. The copy number variations from all samples detected were in the normal range. Conclusion There is methylation aberration of H19-DMR in ICR1 in children with RSS.
