Objective To investigate the effects of hemodialysis combined with hemopurification and comprehensive nursing intervention on the levels of interleukin -6 (IL-6), C-reactive protein (CRP) and β2- microglobulin (β2- MG) in patients with diabetic nephropathy (DN). Methods A total of 68 patients with DN were selected in our hospital, and were treated with hemodialysis combined with hemopurification. The control group was treated with routine nursing intervention, and the observation group was given comprehensive nursing intervention, with 34 cases in each group. The differences in the levels of IL- 6, CRP and β2- MG before and after treatment were compared between the two groups. Results In the control group, the level of IL-6 before treatment [(121.85±34.95) pg/ml] and 1 month after treatment [(120.53 ± 24.95) pg/ml] and 3 months [(119.05 ± 25.73) pg/ml] showed no significant difference (P>0.05). The level of IL-6 in the observation group for 1 month after treatment [(98.90±20.52) pg/ml] and 3 months [(70.32 ± 10.43) pg/ml] was significantly lower than that before treatment, and significantly lower than those in the control group (P<0.05). There was no significant difference in the level of CRPbetween the control group before treatment [(12.64 ± 3.08) mg/L] and 1 month after treatment (12.64±3.15) mg/L] and 3 months [12.89±4.02] mg/L] (P>0.05); the level of CRP at 1 month after treatment [(9.24 ± 3.24)mg/L] and 3 months after treatment [(7.04 ± 2.54)mg/L] in the observation group was significantly lower than that before the treatment, and significantly lower than those in the control group (P<0.05).The level of β2-MG in the control group at 1 month [(10.24±1.79) mg/L] and 3 months after treatment [(9.01 ± 1.47) mg/L] were significantly lower than before the treatment (12.53 ± 3.45) mg/L];thelevel of β2-MG at 1 month [(9.03±1.68) mg/L] and 3 months after treatment [(6.73±1.73)mg/L] in the observation group was also significantly lower thanthat before the treatment, and significantly lower than those in the control group (P<0.05). Conclusions Hemodialysis combined with hemopurification and comprehensive nursing intervention can effectively inhibit the release of inflammatory factors and reduce the inflammatory state, so it has good clinical application value.

Objective: To summarize the gene mutation of early onset epileptic spasm with unknown reason. Method: In this prospective study, data of patients with early onset epileptic spasm with unknown reason were collected from neurological department of Children's Hospital of Fudan University between March 2016 and December 2016. Patients with known disorders such as infection, metabolic, structural, immunological problems and known genetic mutations were excluded. Patients with genetic disease that can be diagnosed by clinical manifestations and phenotypic characteristics were also excluded. Genetic research methods included nervous system panel containing 1 427 epilepsy genes, whole exome sequencing (WES), analysis of copy number variation (CNV) and karyotype analysis of chromosome. The basic information, phenotypes, genetic results and the antiepileptic treatment of patients were analyzed. Result: Nine of the 17 cases with early onset epileptic spasm were boys and eight were girls. Patients' age at first seizure onset ranged from 1 day after birth to 8 months (median age of 3 months). The first hospital visit age ranged from 1 month to 2 years (median age of 4.5 months). The time of following-up ranged from 8 months to 3 years and 10 months. All the 17 patients had early onset epileptic spasm. Video electroencephalogram was used to monitor the spasm seizure. Five patients had Ohtahara syndrome, 10 had West syndrome, two had unclear classification. In 17 cases, 10 of them had detected pathogenic genes. Nine cases had point mutations, involving SCN2A, ARX, UNC80, KCNQ2, and GABRB3. Except one case of mutations in GABRB3 gene have been reported, all the other cases had new mutations. One patient had deletion mutation in CDKL5 gene. One CNV case had 6q 22.31 5.5MB repeats. Ten cases out of 17 were using 2-3 antiepileptic drugs (AEDs) and the drugs had no effect. Seven cases used adrenocorticotropic hormone (ACTH) and prednisone besides AEDs (a total course for 8 weeks). Among them, five cases had no effect and two cases were seizure free recently. A case with GABRB3 (C.905A>G) had seizure controlled for 3 mouths. A case with ARX (C.700G>A) had seizure controlled for 6 mouths. Conclusion The early onset epileptic spasm with unknown reason is highly related to genetic disorders. A variety of genetic mutations, especially new mutations were found. Genetic heterogeneity of epileptic spasm is obvious.

OBJECTIVE: To analyze the clinical phenotype and genetic characteristics of a patient with Alport syndrome. METHODS: A patient with Alport syndrome who had visited the First Affiliated Hospital of Zhengzhou University in November 2020 was selected as the study subject. Clinical data of the patient were collected. High-throughput sequencing was carried out to detect potential variant of the COL4A3, COL4A4 and COL4A5 genes, and Sanger sequencing was carried out for verification of candidate variants in the family. RESULTS: The main clinical manifestations of the patient included hematuria, proteinuria, and impaired hearing. Audiometric testing suggested symmetrical cochlear sensory neural hearing loss on both sides. Renal biopsy revealed mild mesangial proliferative glomerulonephritis. Genetic testing revealed that the patient has harbored compound heterozygous variants of the COL4A4 gene, namely c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp), which were respectively inherited from her father and mother. Neither variant has been reported before, and were predicted to be pathogenic based on the guidelines from the American College of Medical Genetics and Genomics. CONCLUSION The c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp) compound heterozygous variants of the COL4A4 gene probably underlay the Alport syndrome in this patient. Above finding has enriched the mutational spectrum of the COL4A4 gene.

Objective: To explore the optimal and rapid imaging acquisition time and clinical applicability when using high- and low-dose one day rest/stress myocardial perfusion imaging (MPI) with cadmium-zinc-telluride heart dedicated SPECT (CZT-SPECT). Methods: The MPI data with high-dose rest/stress protocol in 51 patients (22 males, 29 females, age: (55.4±8.5) years) between November 2017 and December 2017 and those with low-dose protocol in 50 patients (27 males, 23 females, age: (59.1±12.8) years) between July 2018 and October 2018 were retrospectively analyzed. The MPI was performed with CZT-SPECT. Each patient received 296-370 MBq rest dose of ⁹⁹Tc^m-methoxyisobutylisonitrile (MIBI) for high-dose protocol, 111-222 MBq rest dose of ⁹⁹Tc^m-MIBI for low-dose protocol. Stress dose was 3 times of the corresponding rest dose. Rest and stress scans were acquired 6 min and 4 min for high-dose protocol, while 8 min and 6 min for low-dose protocol in total. All rest or stress imaging data were reconstructed from list-mode raw data to obtain scan durations of 1 min, 2 min, etc, up to the maximum of acquisition time. Image quality at different acquisition times were evaluated, and myocardial perfusion and function parameters were compared. Paired t test, Wilcoxon signed rank test, Pearson correlation and Bland-Altman analyses were used for data analysis. Results: The image quality was rated as excellent/good in all patients (100%, 51/51) when acquisition time ≥3 min and ≥2 min respectively for rest and stress imaging with high-dose protocol, the similar results was obtained (100%, 50/50) when acquisition time ≥4 min and ≥3 min respectively for rest and stress imaging with low-dose protocol. The quantitative perfusion parameters(summed rest scores, summed stress scores, total perfusion deficit) and left ventricle ejection fraction (LVEF) at shorter acquisition times (3 min/2 min, 4 min/3 min) were not significantly different from the results at the longer acquisition times (6 min/4 min, 8 min/6 min; t values: from -1.196 to 1.597, z values: from -1.963 to 1.945, all P>0.05). Those parameters at shorter and longer acquisition times showed strong correlations (all r>0.700, all P<0.001), and Bland-Altman analysis revealed good agreement between them. Conclusion The optimal acquisition time is 3 min/2 min for high-dose one-day rest/stress CZT-SPECT MPI, and 4 min/3 min for low-dose protocol, which can significantly shorten the MPI acquisition time, then reliable perfusion parameters and LVEF can be obtained under the premise of ensuring image quality, making it the better clinical applicability.

Objective: To examine the effects of ursodeoxycholic acid combined with Traditional Chinese Medicine on biochemical response in patients with primary biliary cholangitis. Methods: According to the method of receiving treatment, 197 patients with primary biliary cholangitis were divided into Traditional Chinese Medicine plus Western medicine group (93 cases, 47.2%) and Western medicine group (104 cases, 52.8%). From the baseline date, the combined group was treated with ursodeoxycholic acid plus traditional Chinese medicine decoction or Chinese patent medicine for at least one month and the Western medicine group simply took ursodeoxycholic acid . Additionally, Traditional Chinese medicine decoction prescriptions were mainly Xiaoyaosan and Yinchenhao. Chinese patent medicine were restricted to Biejia Ruangan tablets, Fuzheng Huayu capsules, Jiuweigantai capsules and Yinzhihuang capsules, which were used to treat liver fibrosis and cholestasis. The primary efficacy endpoint was defined as ALP level < 1.67 × ULN and ≥ 15% decrease in ALP with baseline level and TBIL≤ULN after 12 months of treatment. Results: The overall biochemical response rate of patients was 35.0% (69/197). The response rate of TCM+ Western medicine group was 43.0% (40/93), and that of Western medicine group was 27.9% (29/104). The difference between the two groups was statistically significant (χ² = 4.936, P < 0.05). Further analysis showed that the Chinese and Western medicine group was superior to the Western medicine group alone in reducing γ-glutamyltransferase (GGT) and TBiL [the median decline were GGT: 160.1 U/L and 111.3 U/L (Z = -2.474, P < 0.05), TBiL: 5.2 umol/l and 3.1 umol/l (Z = -2.125, P < 0.05)]. Conclusion UDCA combined with TCM therapy can remarkably improve the biochemical response rate in patients with PBC and distinctly decrease the TBIL and GGT levels than UDCA monotherapy.
