Prognostic value of modified Charlson comorbidity index combined with serum albumin for long-term prognosis in peritoneal dialysis patients / 中华肾脏病杂志

Objective:To assess the prognostic value of modified Charlson comorbidity index (mCCI) combined with serum albumin for long-term prognosis in peritoneal dialysis (PD) patients.Methods:From January 1, 2007 to June 30, 2015, patients who started PD in Nanjing Drum Tower Hospital were enrolled in this retrospective cohort study. Clinical data including gender, age, underlying diseases, laboratory examination and prognosis were collected. The mCCI at the beginning of PD was calculated. Whether the duration of PD exceeded 5 years was used as an indicator to evaluate the prognosis. The patients were divided into≥5 years group and<5 years group according to the duration of PD, and the data were compared between the two groups. Cox regression model was constructed to analyze the influencing factors of all-cause death in PD patients. Multivariate logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the predictive value of mCCI and serum albumin levels on whether patients could maintain long-term PD.Results:Of the 183 patients included [males 106(57.9%), females 77(42.1%); (53.35±16.50) years old; 162 cases (88.5%) with hypertension, 55 cases (30.1%) with diabetes], 97 cases had PD duration for ≥5 years and 86 cases less than 5 years. The overall 5-year technical survival rate was 65.1%. At the beginning of PD, compared with the dialysis age≥5 years group, the patients in the dialysis age less than 5 years group had older age, higher mCCI, lower serum albumin level, and higher C-reactive protein (CRP) level (all P<0.05), but there were no significant differences in gender, education level, electrolyte, mean arterial pressure, high densitv lipoprotein (HDL), low-density lipoprotein (LDL) and PD adequacy index between the two groups (all P>0.05). Multivariate logistic regression analysis showed that increased age ( OR=1.022, 95% CI 1.000-1.043, P=0.046), increased mCCI ( OR=1.620, 95% CI 1.300-2.018, P<0.001) and decreased serum albumin ( OR=0.807, 95% CI 0.730-0.893, P<0.001) were independent predictors for the duration of PD<5 years. ROC curve analysis showed that the area under ROC curves ( AUC) of mCCI, serum albumin level and combined prediction probability of the two for the duration of PD<5 years were 0.647(95% CI 0.568-0.727), 0.655(95% CI 0.577-0.734), and 0.767(95% CI 0.700-0.835), respectively, indicating that the accuracy of combined parameters to predict survival outcome was higher than that of any single parameter. Multivariate Cox analysis showed that increased age ( HR=1.073, 95% CI 1.046-1.100, P<0.001), increased mCCI ( HR=1.198, 95% CI 1.044-1.375, P=0.010) and decreased serum albumin ( HR=0.904, 95% CI 0.843-0.969, P=0.004) were independent influencing factors for all-cause death in PD patients. Conclusions:Old age, high mCCI and low serum albumin level are influencing factors for dialysis age<5 years and all-cause death in PD patients. mCCI combined with serum albumin level can improve the accuracy of predicting the long-term dialysis in PD patients.

In each district, children aged 0 - 7 years old who underwent physical examination in township hospitals and prevention and health centers were selected to collect urine samples for urine iodine testing. One township was selected from each district, and one primary school was selected from each township. At least 90 children aged 8 to 12 (half boys and half girls) were selected from each primary school to collect urine samples for urine iodine testing. The urinary iodine levels of children of different genders, ages and regions were compared and analyzed.Results:A total of 2 934 urine samples were collected. The median of urinary iodine was 191.9 μg/L, ranging from 1.4 to 627.9 μg/L, the proportion of urine iodine content < 50 μg/L was 5.5% (162/2 934), the proportion of 50 - 99 μg/L was 10.9% (319/2 934), the proportion of 100 - 199 μg/L was 37.4% (1 096/2 934), the proportion of 200 - 299 μg/L was 28.3% (829/2 934), and the proportion of ≥300 μg/L was 18.0% (528/2 934). A total of 1 535 and 1 399 urine samples of boys and girls were collected. The medians urinary iodine of boys and girls were 202.3 and 177.7 μg/L, respectively, and the difference was statistically significant ( Z = - 5.487, P < 0.05). There were 106, 1 539, 753 and 536 cases of infants (0 - 12 months old), early childhood (1 - 3 years old), preschool children (4 - 6 years old), and school-age children (7 - 12 years old), the medians urinary iodine were 169.8, 189.6, 169.9 and 243.7 μg/L, respectively, the difference was statistically significant ( H = 127.395, P < 0.05). There were 642, 699, 422, 738 and 433 cases in different regions (east, west, south, north and middle) and the medians urinary iodine were 194.2, 172.7, 196.8, 200.5 and 196.6 μg/L, respectively, the difference was statistically significant ( H = 29.461, P < 0.05). Conclusions:Children aged 0 - 12 years old in Dongtai City are not deficient in iodine on the whole, but those with urinary iodine value higher than 200 μg/L account for a large proportion. Therefore, a reasonable iodine nutrition plan should be implemented according to the actual situation. In addition, individual iodine deficiency and excess should also be paid attention to.

Construction and application of effect-related near-infrared spectroscopy for traditional Chinese medicines — Exemplification by rhubarb dispensing granules / 药学学报

Consistency in quality of traditional Chinese medicine granules is an important factor to ensure reproducible clinical efficacy. In this study rhubarb dispensing granules were utilized to construct an efficacious near-infrared spectroscopy (eNIRS) assay by combining NIRS and biopotency. A NIR method for assaying rhubarb dispensing particles was established, and information on different batches was collected. The diarrhea-inducing biopotency of rhubarb dispensing granules was determined based on a constipation model induced by diphenoxylate in mice. The animal protocol was approved by the Animal Ethic Committee​ of 302 Hospital of Chinese PLA People's Liberation Army (ID: IACUC-2019-0010). Ten anthraquinones were determined in rhubarb dispensing granules by UPLC. The correlation between NIR and biopotency was analyzed and five characteristic bands that correlated highly with bioactivity were identified, including 4 011-4 390, 4 859-5 461, 7 012-7 493, 10 992-11 312 and 11 871-12 489 cm-1. There were some differences in the main bands of different chemical constituents. In summary, five active bands based on NIRS were identified and found to be able to achieve rapid on-line detection of rhubarb dispensing granule quality. This research model may also provide reference for quality control of other Chinese medicine dispensing granules.

Research on soluble VEGF receptor 1 in retinal neovascularization / 国际眼科杂志(Guoji Yanke Zazhi)

·The common feature of retinal neovascularization is the formation of pathological neovascularization. The primary one of endogenous retinal neovascularization factor in current research is vascular endothelial growth factor (VEGF). SFlt-1, the soluble form of splicing in mRNA extracellular region of VEGFR - 1, which is short of intracellular tyrosine kinase domain can only encode the extracellular domain. Therefore, it only can bind with ligands but can not transmit signals, thus preventing the formation of neovascularization. SFlt-1,as a hot research topic in recent years, may provide a new gene therapy method for this disease. This review focus on the mechanism and research progress of sFlt-1 in retinal neovascularization.

To investigate the hepatoprotective effect of Schisandrae Chinensis Fructus (SCF) on CCl₄-induced liver injury, observe its effect on serum metabolites, explore its scientific connotation in liver preservation and find the biomarkers for hepatoprotective effect of SCF. Liver injury model was established by using CCl₄. The pathological sections of liver tissues were observed and the contents of alanine transaminase (ALT) and aspartate transaminase (AST) in serum were determined. The metabolic skills were adopted based on ultra performance liquid chromatography time-of-flight mass spectrometry (UPLC-Q-TOF-MS), principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) for screening and identification of biomarkers related to liver injury. The results showed the metabolites in blank group, model group and administration group could be easily distinguished, 50 differential compounds were identified and 7 possible metabolic pathways of liver protection were enriched. In this experiment, the hepatoprotective effect of SCF was verified, and the related metabolic pathways such as amino acid metabolism, vitamin metabolism and glycerophospholipid metabolism were discussed.

New Mutation of Coenzyme Q Monooxygenase 6 Causing Podocyte Injury in a Focal Segmental Glomerulosclerosis Patient / 中华医学杂志(英文版)

Background@#Focal segmental glomerulosclerosis (FSGS) is a kidney disease that is commonly associated with proteinuria and the progressive loss of renal function, which is characterized by podocyte injury and the depletion and collapse of glomerular capillary segments. The pathogenesis of FSGS has not been completely elucidated; however, recent advances in molecular genetics have provided increasing evidence that podocyte structural and functional disruption is central to FSGS pathogenesis. Here, we identified a patient with FSGS and aimed to characterize the pathogenic gene and verify its mechanism.@*Methods@#Using next-generation sequencing and Sanger sequencing, we screened the causative gene that was linked to FSGS in this study. The patient's total blood RNA was extracted to validate the messenger RNA (mRNA) expression of coenzyme Q monooxygenase 6 (COQ6) and validated it by immunohistochemistry. COQ6 knockdown in podocytes was performed in vitro with small interfering RNA, and then, F-actin was determined using immunofluorescence staining. Cell apoptosis was evaluated by flow cytometry, the expression of active caspase-3 was determined by Western blot, and mitochondrial function was detected by MitoSOX.@*Results@#Using whole-exome sequencing and Sanger sequencing, we screened a new causative gene, COQ6, NM_182480: exon1: c.G41A: p.W14X. The mRNA expression of COQ6 in the proband showed decreased. Moreover, the expression of COQ6, which was validated by immunohistochemistry, also had the same change in the proband. Finally, we focused on the COQ6 gene to clarify the mechanism of podocyte injury. Flow cytometry showed significantly increased in apoptotic podocytes, and Western blotting showed increases in active caspase-3 in si-COQ6 podocytes. Meanwhile, reactive oxygen species (ROS) levels were increased and F-actin immunofluorescence was irregularly distributed in the si-COQ6 group.@*Conclusions@#This study reported a possible mechanism for FSGS and suggested that a new mutation in COQ6, which could cause respiratory chain defect, increase the generation of ROS, destroy the podocyte cytoskeleton, and induce apoptosis. It provides basic theoretical basis for the screening of FSGS in the future.

<p><b>OBJECTIVE</b>To investigate the difference in the vulnerability of carotid atherosclerotic plaques in patients with unilateral and bilateral intraplaque hemorrhage (IPH).</p><p><b>METHODS</b>A retrospective analysis was conducted among 44 patients with unilateral IPH (30 cases) or bilateral IPH (14 cases) in the carotid plaques detected by magnetic resonance imaging (MRI) in our hospital between December, 2009 and December, 2012. The age, maximum wall thickness and incidence of fibrous cap rupture were compared between the two groups.</p><p><b>RESULTS</b>Compared with those with unilateral IPH, the patients with bilateral IPHs had a significantly younger age (66.6∓9.4 years vs 73.7∓9.0 years, P=0.027), a significantly greater maximum plaque thickness (6.3∓1.9 mm vs 5.0∓1.3 mm, P=0.035) and a higher incidence of ulcers (50% vs 13.3%, P=0.025). Logistic regression analysis revealed a significant association between bilateral IPHs and the occurrence of ulcer with an odd ratio (OR) of 6.5 (95% confidence interval [CI]: 1.5-28.7, P=0.014). After adjustment for gender in Model 1, bilateral IPHs were still significantly associated with presence of ulcer (OR=5.7, 95%CI: 1.1-29.2, P=0.036). But after adjustment for age (P=0.131) or maximum plaque thickness (P=0.139) in model 2, no significant correlation was found between bilateral IPHs and the presence of ulcer.</p><p><b>CONCLUSION</b>Compared with patients with unilateral IPH, those with bilateral IPHs are at a younger age and have a greater plaque burden and a higher incidence of fibrous cap rupture, suggesting a greater vulnerability of the carotid plaques in patients with bilateral IPHs.</p>

Role of heteroplasmic mutations in the mitochondrial genome and the ID4 gene promoter methylation region in the pathogenesis of chronic aplastic anemia in patients suffering from Kidney yin deficiency / 中国结合医学杂志

<p><b>OBJECTIVE</b>To analyze changes in gene amplification in the mitochondrial genome and in the ID4 gene promoter methylation region in patients with chronic aplastic anemia (CAA) suffering from Kidney (Shen) yin deficiency or Kidney yang deficiency.</p><p><b>METHODS</b>Bone marrow and oral epithelium samples were collected from CAA patients with Kidney yin deficiency or Kidney yang deficiency (20 cases). Bone marrow samples were collected from 20 healthy volunteers. The mitochondrial genome was amplified by polymerase chain reaction (PCR), and PCR products were used for sequencing and analysis.</p><p><b>RESULTS</b>Higher mutational rates were observed in the ND1-2, ND4-6, and CYTB genes in CAA patients suffering from Kidney yin deficiency. Moreover, the ID4 gene was unmethylated in bone marrow samples from healthy individuals, but was methylated in some CAA patients suffering from Kidney yin deficiency (positive rate, 60%) and Kidney yang deficiency (positive rate, 55%).</p><p><b>CONCLUSIONS</b>These data supported that gene mutations can alter the expression of respiratory chain enzyme complexes in CAA patients, resulting in energy metabolism impairment and promoting the physiological and pathological processes of hematopoietic failure. Functional impairment of the mitochondrial respiration chain induced by gene mutation may be an important reason for hematopoietic failure in patients with CAA. This change is closely related to maternal inheritance and Kidney yin deficiency. Finally, these data supported the assertion that it is easy to treat disease in patients suffering from yang deficiency and difficult to treat disease in patients suffering from yin deficiency.</p>

Advances in studies on pharmacological action of main chemical constituent of Curcuma Zedoary in preventing in-stent restenosis / 中国中药杂志

Traditional Chinese medicine Curcuma Zedoary ( E'Zhu) contains essential oil, curcuminoid and other effective constituents, with such pharmacological actions as anti-platelet aggregation, lowing blood lipid, anti-oxidation and anti-inflammation. In recent years, studies have showed that certain extracts and chemical components of E'Zhu could mitigate myocardial cell mitochondria injury and protect vascular endothelium by enhancing heme oxygenase-1 activity, inhibit nuclear factor NF-kappaB, target genes interleukin-associated kinase-1 (IRAK-1), tumor necrosis factor receptor-6 (TRAF-6) and vascular cell adhesion molecule-1 (VCAM-1), reduce inflammatory infiltration, and inhibit growth factor-induced smooth muscle cells (SMCs) proliferation and migration by impacting oxidation of cellular phosphatases. Due to its different functions in vascular endothelial cells and smooth muscle cells, E'Zhu has been applied in drug-eluting stents, with a potential effect in preventing in-stent restenosis and thrombogenesis. In this paper, studies on pharmacological effects and mechanisms of extracts and main chemical constituents from E'Zhu in preventing vascular restenosis were summarized.

Tubulointerstitial fibrosis score was reduced by 17.5%±1.1% at day 7 and by 20.0%±1.2% at day 14 in the UCG-treated group, compared with the UUO group. The UCG could maintained expression of E-cadherin and suppressed expression of vimentin and α-SMA in kidney tissues of UUO rats at days 7 and 14, as determined by Western blot analysis and immunofluorescence staining. Rat serum containing the UCG partially inhibited TGF-β1-induced fibroblast phenotype of HK-2 cells and maintained the epithelial morphology of HK-2 cells in vitro. This occurred partially through a reduction of vimentin expression and an increase of E-cadherin expression.</p><p><b>CONCLUSION</b>These results suggest that the UCG prevents tubular EMT and may be a promising agent for treating tubulointerstitial fibrosis.</p>

Observation on the immediate effects of acupuncture at Yanglingquan(GB 34) on passive movement in cerebral infarction patients / 中国针灸

<p><b>OBJECTIVE</b>To observe central immediate effect of acupuncture at Yanglingquan (GB 34) on passive movement of cerebral infarction paitents with hemiplegia by functional magnetic resonance imaging (fMRI) and provide reference for clinical treatment.</p><p><b>METHODS</b>With 1. 5 T MRI scanner, six cases of right cerebral infarction paitents with left hemiplegia in recovery stage were scanned during passive fingers movement before and after acupuncture at Yanglingquan (GB 34), which was controlled with sham-acupoint acupuncture to observe immediate activated part of the corresponding brain.</p><p><b>RESULTS</b>The activated areas of the passive movement in all the patients were mainly motor sensory cortex on the right side. Compared with sham-acupoint, in the left anterior insula, in ferior frontal gyrus, central gyrus, fusiform gyrus, cerebellum, acupuncture at Yanglingquan (GB 34) has better central effect. These areas were involved with several brain networks.</p><p><b>CONCLUSION</b>The acupuncture at Yan glingquan (GB 34) could promote recover of helmiplegia by regulating motor-related network.</p>

Glycated albumin may be a choice, but not an alternative marker of glycated hemoglobin for glycemic control assessment in diabetic patients undergoing maintenance hemodialysis / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>It has been suggested that glycated hemoglobin (HbA1c) underestimate the actual glycemic control levels in maintenance hemodialysis (MHD) patients, because of anemia and the using of erythropoietin (EPO); it was recommended that glycated albumin (GA) should be an alternative marker. Therefore, the assessment performances of glycemic control were compared between GA and HbA1c in this research by referring to mean plasma glucose (MPG) in diabetes mellitus (DM) patients undergoing MHD or not.</p><p><b>METHODS</b>MPG was calculated according to the data registered at enrollment and follow-up 2 months later and corresponding HbA1c, albumin (ALB), GA, etc. were measured in 280 cases. A case-control study for comparing GA and HbA1c was done among the groups of MHD patients with DM (n=88) and without DM (NDM; n=90), and non-MHD ones with DM (n=102) using MPG for an actual glycemic control standard.</p><p><b>RESULTS</b>In these 3 groups, only for DM patients' (whether undergoing MHD or not), GA and HbA1c correlated with MPG significantly (P < 0.01). Through linear regression analysis, it could be found that the regression curves of GA almost coincided in MHD and non-MHD patients with DM, because the intercepts (2.418 vs. 2.329) and slopes (0.053 vs. 0.057) were very close to each other. On the contrary, regression curves of HbA1c did not coincide in the two groups, because variance of the slopes (0.036 vs. 0.052) were relatively large. Through comparing receiver operating characteristic (ROC) areas under the curve (AUC), it could be understood that the assessment performances of GA and HbA1c in MHD patients were lower than those in non-MHD ones, and assessment performance of HbA1c in MHD patients was better than GA (P < 0.05). In addition, the effects of Hb and EPO dose on HbA1c, or that of ALB on GA were unobvious in our study.</p><p><b>CONCLUSIONS</b>Actual glycemic control level in MHD patients with DM may be underestimated by HbA1c, and it could be avoided by GA; however, glycemic evaluating performance of HbA1c may be still better than that of GA. Therefore, HbA1c should not be replaced completely although GA can be used as a choice to monitor glycemic level.</p>
