Abstract
Objective: To explore the rate of Helicobacter pylori (Hp) resistance to levofloxacin and clarithromycin and the common mutation patterns of resistance genes in Ningxia, and to assess the concordance between phenotypic resistance and genotypic resistance. Methods: Cross-sectional study. Patients diagnosed with Hp infection in 14 hospitals in Ningxia region from February 2020 to May 2022 were retrospectively selected. Hp strains were isolated from gastric biopsy specimens of Hp-infected patients and subjected to phenotypic drug sensitivity testing and detection of resistance genes to analyze the rate of Hp resistance to levofloxacin and clarithromycin and the common mutation patterns of resistance genes in Ningxia region; and the concordance rate and Kappa concordance test were used to assess the concordance between phenotypic resistance and genotypic resistance. Results: A total of 1 942 Hp strains were isolated and cultured, and among the infections, 1 069 cases (55.0%) were male and 873 cases (45.0%) were female, aged (50.0±12.5) years (15-86 years). The rates of Hp resistance to levofloxacin and clarithromycin in Ningxia were 42.1% (818/1 942) and 40.1% (779/1 942), respectively, and the rate of dual resistance to both was 22.8% (443/1 942). The rate of resistance to levofloxacin and clarithromycin of Hp strains from female patients was higher than in male patients (levofloxacin: 50.4%(440/873) vs 35.4%(378/1 069); clarithromycin: 44.4%(388/873) vs 36.6%(391/1 069), both P<0.001). Among the GyrA gene mutations associated with levofloxacin resistance, the differences in mutation rate of amino acid at positions 87 and 91 were statistically significant in both drug-resistant and sensitive strains(both P<0.001), except for Asn87Thr. Hp strains were statistically significant for levofloxacin (Kappa=0.834, P<0.001) and clarithromycin (Kappa=0.829, P<0.001) had good concordance in resistance at the phenotypic and genotypic levels. Conclusion: The resistance of Hp to levofloxacin and clarithromycin in Ningxia region is severe, and there is good consistency between genotypic and phenotypic resistance.

Relationships among the Dosage of Erythropoiesis-Stimulating Agents, Erythropoietin Resistance Index, and Mortality in Maintenance Hemodialysis Patients. Blood Purif 2021; 51:171-181. [PMID: 34175850 DOI: 10.1159/000506536] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2019] [Accepted: 02/13/2020] [Indexed: 11/19/2022]
Abstract
BACKGROUND Erythropoiesis-stimulating agents (ESAs) constitute an important treatment option for anemia in hemodialysis (HD) patients. We investigated the relationships among the dosage of ESA, erythropoietin resistance index (ERI) scores, and mortality in Chinese MHD patients. METHODS This multicenter observational retrospective study included MHD patients from 16 blood purification centers (n = 824) who underwent HD in 2011-2015 and were followed up until December 31, 2016. We collected demographic variables, HD parameters, laboratory values, and ESA dosages. Patients were grouped into quartiles according to ESA dosage to study the effect of ESA dosage on all-cause mortality. The ERI was calculated as follows: ESA (IU/week)/weight (kg)/hemoglobin levels (g/dL). We also compared outcomes among the patients stratified into quartiles according to ERI scores. We used the Cox proportional hazards model to measure the relationships between the ESA dosage, ERI scores, and all-cause mortality. Using propensity score matching, we compared mortality between groups according to ERI scores, classified as either > or ≤12.80. RESULTS In total, 824 patients were enrolled in the study; 200 (24.3%) all-cause deaths occurred within the observation period. Kaplan-Meier analyses showed that patients administered high dosages of ESAs had significantly worse survival than those administered low dosages of ESAs. A multivariate Cox regression identified that high dosages of ESAs could significantly predict mortality (ESA dosage >10,000.0 IU/week, HR = 1.59, 95% confidence intervals (CIs) (1.04, 2.42), and p = 0.031). Our analysis also indicated a significant increase in the risk of mortality in patients with high ERI scores. Propensity score matching-analyses confirmed that ERI > 12.80 could significantly predict mortality (HR = 1.56, 95% CI [1.11, 2.18], and p = 0.010). CONCLUSIONS Our data suggested that ESA dosages >10,000.0 IU/week in the first 3 months constitute an independent predictor of all-cause mortality among Chinese MHD patients. A higher degree of resistance to ESA was related to a higher risk of all-cause mortality.

Abstract
Objective: To investigate the relationship between the expression of hepatocyte nuclear factor-1 α (HNF-1α) and the occurrence and development of liver inflammation and fibrosis in liver tissues of patients with chronic hepatitis B. Methods: Sixty-four patients with chronic hepatitis B who were diagnosed and treated in our hospital from 2011 to 2018 were selected. All patients underwent ultrasound-guided aspiration liver biopsy. The pathological results of liver biopsy were collected for inflammation grading and fibrosis staging. The liver puncture biopsies was collected by paraffin sectioning. The expression of HNF1α in the liver tissue was detected by immunohistochemical staining. Mantel-Haenszel χ(2) test was used for bidirectional ordered grouping data, and Spearman's rank-correlation test was used for rank correlation analysis. Results: There were varying degrees of inflammatory necrosis and fibrosis in the liver tissues of patients with chronic hepatitis B. There was a linear relationship between the expression of HNF1α and the level of inflammation in liver tissues (χ (2)(MH) = 40.70, P < 0.05). The expression of HNF1α in liver tissues of patients with chronic hepatitis B was decreased with the increase of liver inflammation. The expression intensity of HNF1α was negatively correlated with the inflammation grade (r(s) = -0.815, P < 0.05). There was a linear relationship between the expressions of HNF1α and the degree and stage of liver fibrosis (χ (2)(MH) = 31.95, P < 0.05). The expression level of HNF1α in liver tissue was gradually decreased with the aggravation of liver fibrosis. The expression intensity of HNF1α was negatively correlated with fibrosis stage (r(s) = -0.713, P < 0.05). Conclusion: HNF1α is closely related to the occurrence and development of liver tissue inflammation and fibrosis, and is expected to be a sensitive indicator for evaluating the level of liver tissue inflammation and fibrosis in patients with chronic hepatitis B. In addition, its down-regulation may be involved in the process of occurrence and development of liver inflammation and liver fibrosis, and may become a new target for the treatment of chronic hepatitis B.

JOURNAL OF INTEGRATIVE MEDICINE-JIM 2021; 19:111-119. [PMID: 33589406 DOI: 10.1016/j.joim.2021.01.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 12/16/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m2, and 24-hour proteinuria level of 0.5-3.0 g, were recruited in 41 hospitals across 19 provinces in China and were randomly divided into five groups: SYKFT, losartan potassium 50 mg or 100 mg, SYKFT plus losartan potassium 50 mg or 100 mg. MAIN OUTCOME MEASURES The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Environmental Exposure-Associated Human Health Risk of Dioxin Compounds in the Vicinity of a Municipal Solid Waste Incinerator in Shanghai, China. BULLETIN OF ENVIRONMENTAL CONTAMINATION AND TOXICOLOGY 2020; 105:173-179. [PMID: 32632464 DOI: 10.1007/s00128-020-02903-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2020] [Accepted: 06/09/2020] [Indexed: 06/11/2023]
Abstract
In order to assess environmental exposure-associated human health risk of dioxin compounds for the population in the vicinity of a municipal solid waste incinerator (MSWI) in Shanghai, the atmospheric samples (n = 24) and soils samples (n = 96) were collected and analyzed to obtain the concentration level, pollution characteristics and seasonal changes of dioxin compounds in environmental medias. The toxicity equivalent concentration range of 2,3,7,8-substituted polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) was 30.9-409 fg WHO-TEQ·m-3 in atmosphere and 0.362-8.55 ng WHO-TEQ·kg-1 in soil. The non-carcinogenic health risk and carcinogenic health risk from PCDD/Fs environmental exposure of people living in the vicinity of the MSWI in Shanghai were all within the allowable range of the US Environmental Protection Agency, which implied that the MSWI in Shanghai did not produce additional risk for the population living in its vicinity.

Abstract
The present study aimed to assess LH effects on in vitro maturation (IVM) and apoptosis and also to explore the gene expressions of LHR and FSHR in cumulus-oocyte complexes (COCs) of the sheep. COCs were in vitro matured 24h in the IVM medium supplemented with varying concentrations of LH (0, 5, 10, 20 and 30 μg/mL). They were allocated into LH-1 (control group), LH-2, LH-3, LH-4 and LH-5 groups, respectively. FSH (10 IU/mL) addition was as a positive control (FSH group). COCs apoptosis was assessed by TUNEL. The qPCR and Western blotting were utilized to detect mRNA and protein expressions of FSHR and LHR, respectively. The results showed maturation rates of oocytes improved as LH concentration increased from 0 to 10 μg/mL (IU/mL), reaching a peak value of 44.3% in the LH-3 group. Maturation rate of LH-5 group was lower than that of LH-3 and FSH-treated groups. The lowest apoptosis rate was found in LH-3 group. The germinal vesicle break down (GVBD) rates of LH-2, LH-3 and LH-4 groups were also increased in comparison with that found in LH-1 group (control group). GVBD rate of LH-5 was lower than that in LH-3 group. The germinal vesicle (GV) rates in LH-3 and LH-4 groups were lower than those in LH-1 and LH-5 groups (p<0.05, or p<0.01). The lowest GV rate was found in LH-3 group. GV rates in LH-2, LH-4 and LH-5 groups were higher than that in FSH group (p<0.05). At hours 20, 22 and 24 after oocytes IVM, caspase-3 concentrations in four LH-treated groups were decreased in comparison with that in LH-1 group. At 24h, caspase-3 concentrations of LH-2 and LH-3 groups were lower than that in LH-1 group (p<0.05). Expression levels of FSHR and LHR mRNAs rose when LH concentrations in IVM medium increased. The greatest expressions of FSHR and LHR mRNAs were found in LH-5 and LH-3 groups (p<0.01) in comparison with those in the control group (LH-1). Meanwhile, FSHR mRNA expressions in LH-2, LH-3 and LH-4 groups were lower than that in FSH group (p<0.01 or p<0.05). Expression levels of FSHR proteins revealed no significant differences among all groups. Expression levels in LHR proteins were increased. LHR protein level in LH-2 group was higher than that in LH-1 group. In conclusion, LH treatment could promote the maturation rate and GVBD rate. LH reduced apoptosis rate, GV rate of sheep oocytes, and caspase-3 concentrations in IVM medium fluids and additionally enhanced expressions of FSHR and LHR mRNAs of sheep COCs.

Abstract
To enhance in vitro dissolution of Cur by preparing Cur solid dispersions. The ability of HPMCAS-HF,HPMCAS-MF,HPMCAS-LF and PVPK30 to maintain supersaturated solution was investigated by supersaturation test. Amorphous solid dispersions were prepared by the solvent-evaporation method. The prepared samples were characterized using infrared spectroscopy( IR) and differential scanning calorimetry( DSC),and in vitro dissolution was investigated. DSC and IR results showed that in 1 ∶3 and 1 ∶9 solid dispersions,Cur was amorphously dispersed in the carrier,and the interaction existed between drug and carrier. The supersaturation test showed that the order of the ability of polymer to inhibit crystallization of Cur was MF>HF>LF>K30. The dissolution results showed that Cur-K30 amorphous solid dispersion had the highest drug release rate; Cur-K30 and Cur-LF amorphous solid dispersions had a quicker but not stable dissolution rate,and the drug concentration decrease after 4 h; Cur-MF and Cur-HF solid dispersions had a low dissolution,which however increased steadily,attributing to the strong ability of the polymers to inhibit the crystallization of Cur. HPMCAS could inhibit the degradation of Cur better than K30,especially MF and HF. The amorphous solid dispersions of cur significantly enhanced the dissolution of Cur and improved the chemical stability of Cur. This study can provide a basis for the rational selection of the polymer used for Cur solid dispersion.

Abstract
Objective: To detect 20 common deafness gene mutations in non-syndromic hearing loss patients in China using the melting curve method, and analyze and summarize the mutation data to explore the clinical value of this method. Methods: The real-time fluorescence PCR melting curve method was used to detect 20 common mutations of four deafness genes(GJB2,GJB3,SLC26A4 and mtDNA) in 492 patients with non-syndromic hearing loss recruited between March 2014 and September 2016 from the Otolaryngology Department of Xiangya Hospital, Central South University(283 males and 209 females, the age ranged from 1 to 48 years old). The Sanger sequencing method was used to compare the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the deafness mutation detected by the real-time fluorescence PCR melting curve method. Results: A total of 492 samples were detected. 193 wild-type samples, 93 homozygous mutant samples, 145 heterozygous mutant samples, 59 composite heterozygous mutant samples and 2 samples with unknown mutations were detected using the real-time fluorescence PCR melting curve method within the range of 20 gene mutations, whichwere identical to the Sanger sequencing results.The two samples were detected as unknown mutations by the real-time fluorescent PCR melting curve method were confirmed by Sanger sequencing, including a composite heterozygous mutant sample and a homogenous mutation sample. GJB2 c.235delC and SLC26A4 c.919-2 A>G were the most common hotspot mutations in this study, followed by mtDNA m.1555 A>G. Compared with the Sanger sequencing method, the sensitivity, specificity, positive predictive value, negative predictive value, and total coincidence rate of the real-time fluorescence PCR melting curve method were 100%, the Youden's index was 1.0, and the Kappa value was 1. Conclusions: The real-time fluorescence PCR melting curve method is suitable for the detection of deafness gene mutations. It has the advantages in terms of simple, rapid, high sensitivity and strong specificity and can accurately detect the 20 gene mutations of 4 common deafness genes in Chinese population, which is expected to be used for the clinical detection of deafness genes in the future.

Abstract
Background Effective evaluation or prediction of therapy response could be helpful for treatment of chronic kidney disease (CKD), which may rely on accurate biomarkers. Acylcarnitines are involved with lipid metabolism and mitochondrial function. The relation of acylcarnitines with treatment response in patients with CKD is unknown. The purpose of this study is to investigate the association of plasma acylcarnitines with renal function and its alteration by intervention in patients with IgA nephropathy (IgAN). Methods A retrospective study was performed in 81 IgAN patients with treatment by traditional Chinese medicine (TCM). Multivariate linear regression analyses were performed to identify the association of acylcarnitines with baseline estimated glomerular filtration rate (eGFR) and eGFR changes after treatment. Results Twenty-seven acylcarnitines were measured at baseline and after 1-year TCM intervention. Certain short-chain and median-chain acylcarnitines were independently associated with baseline eGFR and eGFR alterations after 1 year treatment. Particularly, patients with high C5:1(β = − 0.42), C8:1(β = − 0.49), C3DC(β = − 0.5), C10:1(β = − 0.36) and C5DC(β = − 0.64)at baseline would have worse prognosis and treatment response. Moreover, certain acylcarnitines could be changed along with the eGFR alteration after 1-year TCM treatment. Conclusions The findings indicate a significant association between plasma acylcarnitines with prognosis and treatment responses in patients with IgAN, which suggest its role as a potential penal of biomarker for IgAN.

Abstract
Background: Patients on hemodialysis have a high-mortality risk. This study analyzed factors associated with death in patients on maintenance hemodialysis (MHD). While some studies used baseline data of MHD patients, this study used the most recent data obtained from patients just prior to either a primary endpoint or the end of the study period to find the characteristics of patients preceding death. Methods: Participants were selected from 16 blood purification centers in China from January 2012 to December 2014. Patients’ data were collected retrospectively. Based on survival status, the participants were divided into two groups: survival group and the death group. Logistic regression analysis was performed to determine factors associated with all-cause mortality. Results: In total, 4104 patients (57.58% male, median age 59 years) were included. Compared with the survival group, the death group had more men and more patients with diabetic nephropathy (DN) and hypertensive nephropathy. The patients preceding death also had lower levels of diastolic blood pressure, hemoglobin, serum albumin, serum calcium, serum phosphate, Kt/V, and higher age. Multivariate analysis revealed that male sex (odd ratio [OR]: 1.437, 95% confidence interval [CI]: 1.094–1.886), age (OR: 1.046, 95% CI: 1.036–1.057), and presence of DN (OR: 1.837, 95% CI: 1.322–2.552) were the risk factors associated with mortality. High serum calcium (OR: 0.585, 95% CI: 0.346–0.989), hemoglobin (OR: 0.974, 95% CI: 0.967–0.981), albumin (OR: 0.939, 95% CI: 0.915–0.963) levels, and dialysis with noncuffed catheter (OR: 0.165, 95% CI: 0.070–0.386) were protective factors based on a multivariate analysis. Conclusions: Hemodialysis patients preceding death had lower hemoglobin, albumin, and serum calcium levels. Multivariate analysis showed that male sex, age, DN, low hemoglobin, low albumin, and low serum calcium were associated with death in hemodialysis patients.

Abstract
Objective: To explore the effects of allogeneic bone marrow mesenchymal stem cells (BMSCs) on polarization of peritoneal macrophages isolated from rats with sepsis induced by endotoxin/lipopolysaccharide (LPS). Methods: (1) BMSCs were isolated, cultured and purified from 5 SD rats with whole bone marrow adherent method. The third passage of cells were collected for morphologic observation, detection of expressions of stem cell surface markers CD29, CD44, CD45, and CD90 with flow cytometer, and identification of osteogenic and adipogenic differentiation. (2) Another 45 SD rats were divided into sham injury group (SI, n=5), LPS control group (LC, n=20), and BMSCs-treated group (BT, n=20) according to the random number table. Rats in groups LC and BT were injected with LPS (5 mg/kg) via tail vein to induce sepsis; rats in group SI were injected with the same amount of normal saline to simulate the damage. At post injury hour (PIH) 1, rats in group BT were given 1 mL BMSCs (2×10(6)/mL) via tail vein injection; rats in another two groups were injected with equal volume of phosphate buffer saline. Five rats in group SI at PIH 24 and in groups LC and BT at PIH 6, 12, 24, and 48 were sacrificed to harvest lung tissue for pathological observation with HE staining. In addition, rats in group SI at PIH 24 and in groups LC and BT at PIH 24 and 48 were simultaneously performed with intraperitoneal injection of low-glucose DMEM. Then peritoneal fluid was harvested to culture peritoneal macrophages. Flow cytometer was used to assess the positive expression of cell makers of macrophages including CD68 (making gate), CD11c, and CD206 in group SI at PIH 24 and in groups LC and BT at PIH 24 and 48. Data were processed with one-way analysis of variance and LSD test. Results: (1) The third passage of cells showed uniform fiber-like shape similar to fibroblasts. These cells showed positive expressions of CD29, CD44, CD90 and weak positive expression of CD45. They were able to differentiate into osteoblasts and adipocytes. These cells were identified as BMSCs. (2) At PIH 24, the structure of pulmonary alveoli of rats in group SI was clear and complete with no congestion or inflammatory cell infiltration. At PIH 6, the structure of pulmonary alveoli of rats in groups LC and BT was clear with a small amount of inflammatory cell infiltration, slight congestion and pulmonary interstitial thickening. At PIH 12, the inflammatory responses in lung tissue of rats in group LC were more severe than those in group BT with a large amount of inflammatory cell infiltration, serious congestion, and obvious pulmonary interstitial thickening. The pathological results of rats in group BT at PIH 12 was consistent with the results at PIH 6. At PIH 24, the pathological results of rats in groups LC and BT were similar to the results at PIH 12. At PIH 48, the structure of pulmonary alveoli tissue of rats in group LC was still severely disrupted, with a large number of inflammatory cell infiltration and congestion in lung tissue, but pulmonary interstitial thickening was slightly alleviated than before. The condition of rats in group BT nearly recovered to that in group SI. (3) At PIH 24, the positive expression rate of CD11c in peritoneal macrophages of rats in group LC [(83±10)%] was close to that in group BT [(87±7)%, P>0.05], and they were both significantly higher than the rate in group SI [(55±12)%, with P values below 0.01]. The positive expression rate of CD11c in peritoneal macrophages of rats in group LC [(59±11)%] at PIH 48 was close to that in group SI at PIH 24 (P>0.05), and they were both significantly higher than the rate in group BT [(20±11)%] at PIH 48 (with P values below 0.01). At PIH 24, the positive expression percentages of CD206 in peritoneal macrophages of rats were similar among the three groups (with P values above 0.05). The positive expression percentage of CD206 in peritoneal macrophages of rats in group SI at PIH 24 was close to that in group BT at PIH 48 (P>0.05), and they were both significantly lower than the percentage in group LC at PIH 48 (with P values below 0.01). Conclusions: BMSCs can reduce the pathological inflammatory responses in the lung of rats with sepsis and inhibit peritoneal macrophages from polarizing into M1 phenotype, whereas they can not promote macrophages to polarize into M2 phenotype.

Abstract
Cerebral edema causes intracranial hypertension (ICH) which leads to severe outcome of patients in the clinical setting. Effective anti-edema therapy may significantly decrease the mortality in a variety of neurological conditions. At present drug treatment is a cornerstone in the management of cerebral edema. Osmotherapy has been the mainstay of pharmacologic therapy. Mannitol and hypertonic saline (HS) are the most commonly used osmotic agents. The relative safety and efficacy of HS and mannitol in the treatment of cerebral edema and reduction of enhanced ICP have been demonstrated in the past decades. Apart from its osmotic force, HS exerts anti-edema effects partly through inhibition of Na(+)-K(+)-2Cl(-) Cotransporter-1 (NKCC1) and aquaporin 4 (AQP4) expression in astrocytes. Melatonin may also reduce brain edema and exert neuroprotective effect on several central nervous system diseases through inhibition of inflammatory response. The inhibitors of Na/H exchanger, NKCC and AQP4 may attenuate brain edema formation through inhibition of excessive transportation of ion and water from blood into the cerebral tissue. In this review we survey some of the most recent findings in the drug treatment of brain edema focusing on the use of osmotherapy, melatonin and inhibitors of ion cotransporters and water channels. A better understanding of the molecular mechanism of these agents would help to improve in the clinical management of patients with brain edema.

Abstract
This was the first multicenter, cross-sectional survey to assess the prevalence of anemia, patient awareness, and treatment status in China. Data of patients with chronic kidney disease (CKD; age, 18-75 years; both out- and inpatients) from 25 hospitals in Shanghai, seeking medical treatment at the nephrology department, were collected between July 1, 2012 and August 31, 2012. The prevalence, awareness, and treatment of anemia in patients with nondialysis CKD (ND-CKD) were assessed. Anemia was defined as serum hemoglobin (Hb) levels ≤12 g/dL in women and ≤13 g/dL in men. A total of 2420 patients with ND-CKD were included. Anemia was established in 1246 (51.5%) patients: 639 (51.3%) men and 607 (48.7%) women. The prevalence of anemia increased with advancing CKD stage (χtrend = 675.14, P < 0.001). Anemia was more prevalent in patients with diabetic nephropathy (68.0%) than in patients with hypertensive renal damage (56.6%) or chronic glomerulonephritis (46.1%, both P < 0.001). Only 39.8% of the anemic patients received treatment with erythropoietin and 27.1% patients received iron products; furthermore, 22.7% of the patients started receiving treatment when their Hb level reached 7 g/dL. The target-achieving rate (Hb at 11-12 g/dL) was only 8.2%. Of the 1246 anemia patients, only 7.5% received more effective and recommended intravenous supplementation. Anemia is highly prevalent in patients with ND-CKD in China, with a low target-achieving rate and poor treatment patterns. The study highlights the need to improve multiple aspects of CKD management to delay the progression of renal failure.

Abstract
We compared polychlorinated dibenzo-p-dioxin and dibenzofuran (PCDD/F) concentrations [expressed as toxic equivalent quantities (TEQs)] in agricultural soil samples from Chongming Island (Shanghai, China) determined using two analytical approaches, an enzyme-linked immunoassay (EIA) method and a high resolution gas chromatography-high resolution mass spectrometry (HRGC/HRMS) method. The PCDD/F concentrations in all 31 soil samples were at background levels (7.30-16.7 pg EIA-TEQ/g from the EIA analysis and 0.526-1.99 pg WHO-TEQ/g from the HRGC/HRMS analysis). Although, the EIA method overestimated the PCDD/F concentrations compared with the concentrations determined using the HRGC/HRMS method. The absence of false-negatives showed by the EIA analysis verified that this method is useful for preliminary sample screening (prior to HRGC/HRMS analysis) and the preliminary characterization of potentially contaminated sites.

Association of IL-1, IL-18, and IL-33 gene polymorphisms with late-onset Alzheimer׳s disease in a Hunan Han Chinese population. Brain Res 2014; 1596:136-45. [PMID: 25446437 DOI: 10.1016/j.brainres.2014.11.019] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2014] [Revised: 11/02/2014] [Accepted: 11/06/2014] [Indexed: 12/14/2022]
Abstract
Interleukin (IL)-1 plays an important role in Alzheimer׳s disease (AD), and single nucleotide polymorphisms (SNPs) in the IL-1 gene have been shown to be associated with AD susceptibility. IL-18 and IL-33 are proinflammatory cytokines of the IL-1 family, and increasing evidence has accumulated to support their crucial role in AD pathogenesis. To examine whether SNPs in IL-1α (rs1800587), IL-1β (rs1143627), IL-18 (rs187238), and IL-33 (rs11792633) are associated with late-onset Alzheimer׳s disease (LOAD) in a Hunan Han Chinese population, we carried out a case-control study involving 201 LOAD patients and 257 healthy controls. No significant differences were found in genotype frequencies of rs1800587 between LOAD patients and controls (P=0.079), but the T allele of rs1800587 was associated with a significantly increased risk of LOAD (P=0.032, odds ratio (OR)=1.592). Significant differences in genotype (P=0.004) and allele (P=0.001) frequencies of rs11792633 were found between LOAD patients and controls, but not for rs1143627 (P=0.535, 0.262, respectively) or rs187238 (P=0.257, 0.139, respectively). The T allele of rs11792633 was found to be a protective factor for LOAD (OR=0.648). These findings suggest that the IL-1α SNP rs1800587 and IL-33 SNP rs11792633, but not the IL-1β SNP rs1143627 or the IL-18 SNP rs187238, contribute to LOAD susceptibility in the Hunan Han Chinese population.

Abstract
Sepsis-associated encephalopathy (SAE) is a neurological dysfunction induced by sepsis, which is associated with high morbidity and mortality. However, at present, the cellular and molecular mechanisms of SAE have remained elusive. The pathogenesis of SAE is complex and multifactorial, in which activated inflammation is recognized as a major factor. Pathological characteristics of SAE include blood- brain barrier (BBB) disruption, reduction of cerebral blood fluid (CBF) and glucose uptake, inflammatory response and activation of microglia and astrocytes. The BBB disruption induces the leakage of immune cells and inflammatory mediators, which trigger an inflammatory response in the brain. Inflammatory mediators released by activated microglia and astrocytes cause neuronal loss and brain function defect. In the review we describe the most recent findings in the pathogenesis of SAE and focus on summarizing the major mechanisms related to SAE pathogenesis.

Abstract
BACKGROUND A multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage. METHODS Adult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices. RESULTS Changes of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that. CONCLUSIONS The domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.

Abstract
AIM OF THE STUDY Podocytes injury mediated by complement complex C5b-9 is the main feature of membranous nephropathy (MN). Little work has been done to prove that ginsenoside-Rg1 could inhibit this process. Our study aims to investigate the efficacy of ginsenoside-Rg1 in protecting the podocyte from complement mediated injury. MATERIALS AND METHODS We chose sublethal C5b-9 induced podocyte injury as the model of MN in vitro. Ginsenoside-Rg1 was given as an intervention. Morphological changes were observed by electron microscope and fluorescence microscope. The production of reactive oxygen species (ROS) was detected by flow cytometry. The expression of the mitogen activated protein kinase (MAPK) including JNK, ERK and P38 was detected by western-blot technique. RESULTS Ginsenoside-Rg1 could protect foot processes of podocytes, suppress the damage of F-actin, decrease the production of ROS, and inhibit the activation of P38 kinase pathway. CONCLUSION These results suggest that ginsenoside-Rg1 could protect podocyte from sMAC-induced injury partly because of its antioxidant property and inhibit the activation of P38 kinase pathway.

Abstract
A study was conducted on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/F) in agricultural soils at 41 sites within a radius of 3 km from two municipal solid waste incinerators in Shanghai. The PCDD/F concentrations ranged from 71.32 to 3,881.44 pg g⁻¹ (0.64-61.15 pg I-TEQ g⁻¹). The highest PCDD/F concentrations were found approximately 1,000 m from the municipal solid waste incinerators. The PCDD/F homologue profiles of all soil samples were compared with the profiles from suspected PCDD/F sources by multivariate statistical analysis. The results showed that, the PCDD/F pollutions in some soil samples can be attributed to emissions from the municipal solid waste incinerators.

Abstract
OBJECTIVE To observe the correlation between traditional Chinese medicine (TCM) syndromes ("deficiency of qi and yin" and "deficiency of liver yin and kidney yin") and A267G in 5'-untranslated region within exonal of megsin gene, and to search the substantial genetic basis for micro-differentiation of TCM syndromes in primary immunoglobulin A nephropathy (IgAN). METHODS A total of 120 IgAN cases meeting the diagnostic criteria were enrolled. The sequence of single nucleotide polymorphism (SNP) of A267G in 5'-untranslated region within exonal of megsin gene was tested. The correlation between SNP and TCM syndromes was observed. RESULTS There were 83 cases carrying GG genotype, 34 cases carrying GA genotype and 3 cases carrying AA genotype in 120 cases of primary IgAN. There was a high proportion of "deficiency of liver yin and kidney yin" in IgAN cases with AA and GA genotypes, and a high proportion of "deficiency of qi and yin" in IgAN cases with GG genotype (P<0.01). Odds ratio in TCM syndrome distribution between GG genotype and GA plus AA genotype was 9.800, and 95% confidence interval was 3.969-24.199. The discrepancy also resided in IgAN patients with different genders and ages. CONCLUSION A267G in 5'-untranslated region within exonal of the megsin gene may be one of the substantial genetic basis for differentiating "deficiency of liver yin and kidney yin" syndrome and "deficiency of qi and yin" syndrome in primary IgAN.

Abstract
Osmotherapy with 10% hypertonic saline (HS) alleviates cerebral edema through osmotic force. Aquaporin-4 (AQP4) has been reported to be implicated in the pathogenesis of cerebral edema resulting from a variety of brain injury. This study aimed to determine if 10% hypertonic saline ameliorates cerebral edema through downregulation of AQP4 expression in the perivascular astrocytes in the ischemic cerebral edema. Adult male Sprague-Dawley (SD) rats were subjected to permanent right-sided middle cerebral artery occlusion (MCAO) and treated with a continuous i.v. infusion of 10% HS. Brain water content (BWC) analyzed by wet-to-dry ratios in the ischemic hemisphere of SD rats was attenuated after 10% HS treatment. This was coupled with the reduction of neuronal apoptosis in the peri-ischemic brain tissue. Concomitantly, downregulated expression of AQP4 in the perivascular astrocytes after 10% HS treatment was observed. Our results suggest that in addition to its osmotic force, 10% HS exerts anti-edema effects possibly through downregulation of AQP4 expression in the perivascular astrocytes. The reduction of brain edema after 10% HS administration can prevent ischemic brain damage.

Abstract
OBJECTIVE To evaluate the therapeutic effect of integrative Chinese and Western medicine in treating mid-advanced crescentic nephritis (MACN). METHODS Thirty-two patients, their diagnosis was confirmed as MACN by renal biopsy, were divided, adopting randomized, controlled method, into two groups, the treated group and the control group, they were all, excepting one, treated with impact therapy of methyl-prednisolone followed with oral intake of prednisone, to part of them cyclophosphamide or mycophenolate mofetil was given in addition, to those with hypo-hemoglobin (< 90 g/L), subcutaneous injection of erythropoietin was administered. Decoction of Qingre Huoxue recipe (QHR), consisted of oldenlandia herb 30 g, honey-suckle stem 30 g, violet herb 30 g, red peony root 15 g, rehmannia root 15 g, solomonseal rhizome 15 g, asiabell root 30 g, red sage root 30 g, prepared rhubarb 12 g and giant-hyssop herb 12 g, were additionally given one dose per day to patients in the treated group. The renal function, improvement of anemia and immunosuppressive agents needed in patients were observed after 3 months treatment. RESULTS After treatment, renal function was improved in both groups, but the effect in the treated group was better than that in the control group (P < 0.05). Anemia was partially alleviated in the two groups with no significant difference. The dosage of glucocorticoids used in the treated group was obviously lesser than that used in the control group (P < 0.01). CONCLUSION Integrative Chinese and western medicine could treat crescentic nephritis to obtain good effect, and reduce the quantity of glucocorticoid necessity for treatment.
