Behavioural Variant Frontotemporal Dementia due to CCNF Gene Mutation: A Case Report.

BACKGROUND: Frontal, temporal lobe dementia (FTD) and amyotrophic lateral sclerosis (ALS) are fatal neurodegenerative diseases. Studies have found that CCNF mutations have been found in patients with familial and sporadic ALS and FTD. Behavioural variant frontotemporal dementia (bvFTD) is a clinical syndrome characterized by progressive deterioration of personality, social behaviour, and cognitive function, which is most closely related to genetic factors. As the early symptoms of bvFTD are highly heterogeneous, the condition is often misdiagnosed as Alzheimer's disease or psychiatric disorders. In this study, a bvFTD patient had a CCNF gene mutation, which led to ubiquitinated protein accumulation and ultimately caused neurodegenerative disease. Genetic detection should be improved urgently for bvFTD patients and family members to provide a clinical reference for early diagnosis of frontotemporal dementia. CASE PRESENTATION: In this case, the patient was 65 years old with an insidious onset, early-onset memory loss, a significant decline in the episodic memory, an early AD diagnosis, and oral treatment with donepezil hydrochloride for 3 years with poor efficacy, followed by a change to oral memantine hydrochloride tablets, which controlled the condition for several months. His medication was switched to sodium oligomannate capsules, and his condition was gradually controlled, but no significant improvement was observed. After spontaneous drug withdrawal, the patient's condition progressed rapidly; therefore, he visited our hospital and underwent neuropsychological tests for moderate to severe cognitive impairment. AD cerebrospinal fluid markers showed no significant abnormalities, and cranial MRI revealed frontotemporal lobe atrophy and decreased hippocampal volume. Genetic testing for the presence of the CCNF gene revealed a c.1532C > A (p. T511N) heterozygous variant, which might be a diagnostic criterion for bvFTD. Therefore, the patient's symptoms recurred after transient improvement with the combination of donepezil, oral memantine hydrochloride tablets, and sodium oligomannate, but his overall condition was improved compared to that before, and this treatment regimen was continued to observe changes during the follow-up. CONCLUSION: The early clinical manifestations of bvFTD are complex and variable, and the condition is easily misdiagnosed, thus delaying treatment. Therefore, for patients with a high clinical suspicion of FTD, in addition to a detailed understanding of their medical history and family history and improvement of relevant examinations, genetic testing should be performed as early as possible to help confirm the diagnosis. For diseases closely related to genes, genetic testing of other family members should be optimised as much as possible to allow early diagnosis and intervention and guide fertility in the next generation.

The role of SUMOylation in the protective mechanisms of therapeutic hypothermia on neonatal hypoxic-ischemic encephalopathy / 中国新生儿科杂志

Objective:To study the role of SUMOylation in the process of therapeutic hypothermia on neural stem cells (NSCs) in neonatal hypoxic-ischemic encephalopathy.Methods:SUMOylation is an essential post-translational modification involving small ubiquitin-like modifiers (SUMOs). Primary-cultured NSCs from mice were assigned into four groups: control group, hypoxia group, hypothermia group and hypoxia+hypothermia group. Western Blot was used to detect the protein levels of SUMO2/3, hypoxia-inducible factor-1α (HIF-1α), peroxisome proliferator-activated receptor γ coactivator factor 1α (PGC-1α) and octamer binding transcription factor 4 (Oct4). The diameters of NSCs were compared. ELISA was used to detect lactate dehydrogenase (LDH) level. Apoptosis was examined using flow cytometry. Immunofluorescence method was used to measure the differentiation of NSCs into neuronal cells.Results:Compared with the control group, the levels of SUMO2/3, HIF-1αand PGC-1α in NSCs of the hypoxia group increased 33%, 126% and 140%, respectively ( P<0.05). Compared with the control group, the levels of SUMO2/3 and PGC-1α in NSCs of the hypothermia group increased 52% and 536%, respectively ( P<0.05). Compared with the hypoxia group, the levels of SUMO2/3, HIF-1α, PGC-1α and Oct4 in the hypoxia+hypothermia group increased 44%, 40%, 230% and 59%, respectively ( P<0.05). The diameters of NSCs in hypoxia group, hypothermia group and hypoxia+hypothermia group were smaller than control group, and hypoxia+hypothermia group smaller than hypoxia group ( P<0.05). No significant differences existed in LDH levels between hypothermia group and control group ( P>0.05). LDH level in hypoxia+hypothermia group were significantly lower than hypoxia group ( P<0.05). No significant differences existed in the cell death rates between hypothermia group and control group ( P>0.05). The cell death rate in hypoxia+hypothermia group was significantly lower than hypoxia group ( P<0.05). Compared with the control group, the expressions of Nestin in both hypoxia group and hypothermia group were increased, but neuron specific enolase (NSE) were decreased ( P<0.05). Compared with hypoxia group and hypothermia group, the level of Nestin in hypoxia+hypothermia group was further increased, while NSE was further decreased ( P<0.05). Conclusions:Therapeutic hypothermia may increase the tolerance of NSCs to hypoxia by enhancing SUMO modification of proteins, providing theoretical basis for the treatment of hypoxic-ischemic encephalopathy with therapeutic hypothermia.

A control study of steroid withdrawal protection strategy after kidney transplantation in children / 中华儿科杂志

Objective: To study the influence of steroid withdrawal protection strategy on height growth in pediatric patients after kidney transplantation. Methods: The prospective cohort study enrolled 40 stage 5 chronic kidney disease children receiving kidney transplantation from July 2017 to September 2022 at Guangzhou Women and Children's Medical Center. Based on the primary preoperative disease, patients with immune abnormality-associated glomerular diseases or unknown causes were assigned to the steroid maintenance group, in which patients received steroid tapering within 3 months after surgery to a maintenance dose of 2.5 to 5.0 mg/d. While patients with hereditary kidney disease or congenital urinary malformations were assigned to the steroid withdrawal group, in which patients had steroids tapered off within 3 months. The characteristics of height catch-up growth and clinical data were compared between the 2 groups at baseline, 6, 12, 18 and 24 months after kidney transplantation. T-test, repeated measurement of variance analysis, Mann-Whitney U test, and Fisher exact test were used for the comparison between the 2 groups. Results: Among the 40 children, 17 were males, 23 were females, 25 were in the steroid withdraw group ((7.8±2.8) years old when receiving kidney transplantation) and 15 cases were in the steroid maintenance group ((7.6±3.5) years old when receiving kidney transplantation). The study population was followed up for (26±12) months. The total dose per unit body weight of steroids in the steroid withdrawal group was lower than that in the steroid maintenance group ((0.13±0.06) vs. (0.36±0.19) mg/(kg·d), t=5.83, P<0.001). The height catch-up rate (ΔHtSDS) in the first year after kidney transplantation in the steroid withdraw and steroid maintenance groups was 1.0 (0.7, 1.4) and 0.4 (0.1, 1.0), respectively; in the second year, the ΔHtSDS in the steroid withdraw group was significantly higher than that in the steroid maintenance group (1.1 (0.2, 1.7) vs. 0.3 (0, 0.8), U=28.00, P=0.039). The HtSDS in the steroid withdrawal group at the five follow-up time points was -2.5±0.8, -2.0±0.8, -1.5±0.8, -1.3±0.9 and -0.5±0.3, respectively, while in the steroid maintenance was -2.4±1.3, -2.2±1.1, -2.0±1.0, -1.8±1.0 and -1.6±1.0, respectively. There were statistically significant differences in HtSDS at different follow-up time points in both 2 groups (F=19.81, P<0.01), but no statistical differences in overall impact between the 2 groups (F=1.13, P=0.204). The steroid treatment was interaction with the increase of follow-up time (F=3.62, P=0.009). At the 24th month after transplantation, the HtSDS in the steroid withdrawal group was significantly higher than that in the steroid maintenance group (P=0.047). Six patients in the steroid withdrawal group experienced antibody-mediated immune rejection (AMR), while 3 did in the steroid maintenance group. Moreover, there was no significant difference in AMR between the two groups (χ2=0.06, P=0.814). Conclusion: The steroid withdrawal protection strategy favors the height catch-up growth in pediatric patients after kidney transplantation and does not increase the risk of postoperative antibody-mediated immune rejection.

Prevalence and treatment of anemia in chronic kidney disease patients based on regional medical big data / 中华流行病学杂志

Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.

Quality evaluation of Bupleuri Radix in Shanxi Province by LC-MS based pseudotargeted metabonomics / 药学学报

Bupleuri Radix is commonly used in the traditional Chinese medicine, and saikosaponins are the important active ingredients. In this study, we first established a relative quantitative method for 25 saikosaponins using ultra high performance liquid chromatography-triple quadrupole mass spectrometry (UHPLC-QTrap-MS) in the scheduled multiple reaction monitoring (sMRM) mode. The established method showed good intra-day and intra-day precision, linearity, repeatability and stability. Then the method was applied to compare 37 batches of Bupleuri Radix from different planting areas. The results showed that there was no significant difference in the saikosaponins composition of Bupleuri Radix from different planting areas in Shanxi Province, which indicating that Bupleuri Radix is well adapted to the environment, so it is suitable for widely planting. However, Bupleuri Radix harvested at spring and autumn were differed from those harvested at summer, which indicated that the traditional harvesting experience was reasonable. Correlation analysis showed that saikosaponins a and d were positively correlated with some saponins, and 4 saponins (such as clinoposaponin XII) showed bigger content variation were identified by coefficient of variation analysis. The LC-MS based pseudotargeted metabonomic method established in this study can be applied to the comprehensive detection of saikosaponins, which providing new method for the quality evaluation of Bupleuri Radix.

Based on the metabolic mechanism of UHPLC-Q-Exactive-MS Hippocampus to delay the aging of Drosophila melanogaster / 药学学报

Based on the UHPLC-Q-Exactive-MS metabonomics technology, the effect of Hippocampus kuda Bleeker on the life span of Drosophila melanogaster was studied, and the change rule of endogenous metabolites in the aging process of Drosophila melanogaster after the intervention of Hippocampus kuda Bleeker japonicus was explored to clarify the anti-aging mechanism of Hippocampus. The natural aging model of Drosophila melanogaster was used. Different doses of raw Hippocampus and fried Hippocampus were given to observe the effects on the life span, climbing ability, sexual activity, and antioxidant enzyme activity of Drosophila melanogaster. Based on UHPLC-Q-Exactive-MS metabolomics technology, the metabolic profile of the aging Drosophila melanogaster was analyzed using metabonomics technology to explore the mechanism of Hippocampus kuda Bleeker delaying the aging of Drosophila melanogaster. The results showed that raw Hippocampus and crispy Hippocampus (1, 4 mg·mL-1) could significantly prolong the average life span, median life span and maximum life span of male fruit flies, and significantly improve the climbing ability and sexual vitality of fruit flies. Catalase (CAT) and aldehyde content were increased, while malonaldehyde (MDA) content was decreased. Through metabonomics technology, it was identified that the Hippocampus can significantly recall 16 metabolites and participate in the biosynthesis of phenylalanine, tyrosine and tryptophan, starch and sucrose metabolism, tyrosine metabolism, cysteine and methionine metabolism, and histidine metabolism. The anti-aging mechanism is related to amino acid metabolism and sugar metabolism, which provides a substantial scientific basis for the development and utilization of Hippocampus and clarifying its role in senile diseases. The animal experiment of this study was approved by the Ethics Committee of Shanxi University (approval number: SXULL2021028).

Recent research on the application of defoamers in children undergoing digestive endoscopy / 中国当代儿科杂志

Endoscopy is a common tool for the diagnosis and treatment of gastrointestinal disorders in children. The presence of bubbles in the gastrointestinal tract is one of the important factors affecting the clarity of endoscopic visual field, and the application of defoamers can significantly reduce bubbles in the gastrointestinal tract, improve the quality of gastrointestinal preparation, and further increase disease detection rate. Various studies have been conducted on gastrointestinal preparation before endoscopy in children, but there still lacks a uniform protocol for the application of defoamers. This article summarizes the use of defoamers in children before digestive endoscopy and related research advances and points out that existing studies on defoamers have a small sample size and that there are still controversies over the selection and timing of administration, so as to provide a reference for in-depth research on defoamers in the future.

Characterization and phylogenetic analysis of complete chloroplast genome of cultivated Qinan agarwood / 中国中药杂志

"Tangjie" leaves of cultivated Qinan agarwood were used to obtain the complete chloroplast genome using high-throughput sequencing technology. Combined with 12 chloroplast genomes of Aquilaria species downloaded from NCBI, bioinformatics method was employed to determine the chloroplast genome characteristics and phylogenetic relationships. The results showed that the chloroplast genome sequence length of cultivated Qinan agarwood "Tangjie" leaves was 174 909 bp with a GC content of 36.7%. A total of 136 genes were annotated, including 90 protein-coding genes, 38 tRNA genes, and 8 rRNA genes. Sequence repeat analysis detected 80 simple sequence repeats(SSRs) and 124 long sequence repeats, with most SSRs composed of A and T bases. Codon preference analysis revealed that AUU was the most frequently used codon, and codons with A and U endings were preferred. Comparative analysis of Aquilaria chloroplast genomes showed relative conservation of the IR region boundaries and identified five highly variable regions: trnD-trnY, trnT-trnL, trnF-ndhJ, petA-cemA, and rpl32, which could serve as potential DNA barcodes specific to the Aquilaria genus. Selection pressure analysis indicated positive selection in the rbcL, rps11, and rpl32 genes. Phylogenetic analysis revealed that cultivated Qinan agarwood "Tangjie" and Aquilaria agallocha clustered together(100% support), supporting the Chinese origin of Qinan agarwood from Aquilaria agallocha. The chloroplast genome data obtained in this study provide a foundation for studying the genetic diversity of cultivated Qinan agarwood and molecular identification of the Aquilaria genus.

A myeloid program associated with COVID-19 severity is decreased by therapeutic blockade of IL-6 signaling

Altered myeloid inflammation and lymphopenia are hallmarks of severe infections, including with SARS-CoV-2. Here, we identified a gene program, defined by correlation with EN-RAGE (S100A12) gene expression, which was up-regulated in airway and blood myeloid cells from COVID-19 patients. The EN-RAGE program was expressed in 7 cohorts and observed in patients with both COVID-19 and acute respiratory distress syndrome (ARDS) from other causes. This program was associated with greater clinical severity and predicted future mechanical ventilation and death. EN-RAGE+ myeloid cells express features consistent with suppressor cell functionality, with low HLA-DR and high PD-L1 surface expression and higher expression of T cell-suppressive genes. Sustained EN-RAGE signature expression in airway and blood myeloid cells correlated with clinical severity and increasing expression of T cell exhaustion markers, such as PD-1. IL-6 treatment of monocytes in vitro upregulated many of the severity-associated genes in the EN-RAGE gene program, along with potential mediators of T cell suppression, such as IL-10. Blockade of IL-6 signaling by tocilizumab in a placebo-controlled clinical trial led to a rapid normalization of ENRAGE and T cell gene expression. This identifies IL-6 as a key driver of myeloid dysregulation associated with worse clinical outcomes in COVID-19 patients and provides insights into shared pathophysiological mechanisms in non-COVID-19 ARDS.

Validation the clinical value of good outcome following attempted resuscitation scores in Chinese populations in predicting the prognosis of in-hospital cardiac arrest / 中华危重病急救医学

Objective:To verify the clinical value of the good outcome following attempted resuscitation (GO-FAR) score in predicting the neurological status of patients with in-hospital cardiac arrest (IHCA) in the Chinese population.Methods:The clinical data of patients with IHCA who were admitted to the Zigong Fourth People's Hospital from January 1 to December 31, 2020 were retrospectively analyzed. Used Glasgow-Pittsburgh cerebral performance category (CPC) score 1 point as the end point, the subjects were divided into 4 groups according to the score: ≤ 0 group, 1-8 group, 9-20 group and ≥ 21 group. Taken the group which GO-FAR score ≤ 0 as the reference group, the odds ratio ( OR) of the other three groups compared with this group was calculated. The receiver operator characteristic curve (ROC curve) was performed to evaluate the predictive value of the GO-FAR score in favorable neurological outcome. A calibration curve was drawn for the Hosmer-Lemeshow test to analyze the degree of calibration of the GO-FAR score for predicting good neurological outcome. Results:A total of 230 IHCA patients were enrolled in the study, including 130 males, aged 74 (65, 81) years old, and 23 case (10.0%) had good neurological prognosis. There were statistically significant differences in GO-FAR-related variables, including age, a normal neurological function on admitted, acute stroke, metastatic cancer, septicemia, medical noncardiac admission, hepatic insufficiency, hypotension, renal insufficiency or dialysis, respiratory insufficiency, pneumonia, etc (all P < 0.05). Taken the GO-FAR score ≤ 0 group as the reference group, the OR values of good neurological prognosis in the GO-FAR score 1-8 group were 0.54 [95% confidence interval (95% CI) was 0.17-1.53, P = 0.250], 9-20 group were 0.17 (95% CI was 0.02-0.67, P = 0.009) and ≥ 21 group were 0.25 (95% CI was 0.05-0.85, P = 0.025). The area under the ROC curve (AUC) of the GO-FAR score for predicting favorable neurological outcome in IHCA patients was 0.653 (95% CI was 0.529-0.777, P = 0.015) and there was no significant difference in Hosmer-Lemeshow test ( P = 0.311). All these suggested that there was no significant difference between the predicted value and the actual value. Conclusions:GO-FAR score can be applied to predict neurological prognosis of IHCA patients in Chinese population. It can help clinicians to predict the prognosis of cardio-pulmonary resuscitation (CPR) and propose critical recommendations in treatment for these patients or their families.

Objective To analyze the trend of death level and the probability of premature death caused by chronic obstructive pulmonary disease (COPD) in Jinshan District of Shanghai from 1980 to 2020, and to provide reference for the formulation of prevention and control measures of COPD. Methods The death cases of COPD in Jinshan District from 1980 to 2020 were collected through the death cause registration information system. The crude mortality, standardized mortality, age group mortality, early death probability and annual change percentage in different periods were calculated. Results From 1980 to 2020, the crude mortality of COPD in Jinshan District was 154.38/100 000, and the standardized mortality was 82.66/100,000. In the past 41 years, the standardized mortality of COPD showed a downward trend in males and females (APC=-1.79%, -2.52%, P<0.001). In the same period, the mortality of COPD in subjects aged 30-69 years old and subjects aged 70 years old and above also decreased (APC=-8.79%, -4.79%, P<0.001), and the probability of premature death caused by COPD showed a downward trend in males and females (APC=-9.61%, -10.71%, P<0.001). Conclusion The mortality rate and the probability of premature death of COPD in Jinshan District have decreased in the past 41 years. However, COPD is still one of the major chronic diseases that pose a serious threat to the health of residents in Jinshan District. Comprehensive prevention and treatment measures should be taken to reduce the mortality and the probability of premature death of COPD.

Postoperative rehabilitation effect and influence factors of adult prelingual deafness with cochlear implant / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate whether pre-lingual deafness adult caused by inadequate auditory compensation in childhood can benefit from cochlear implants and the related influencing factors. Methods: A total of 26 prelingual deafness as experimental group [11 males and 15 females, the age of operation was (24.5±5.7) years] and 13 postlingual deafness as control group [5 males and 8 females, the age at the time of operation was (42.2±11.4) years] were recruited. Objective assessment included hearing threshold and speech recognition rate tests while wearing cochlear implants. Subjective assessment used Nijmegen Cochlear Implant Questionnaire to assess hearing-related quality of life of subjects. The changes of hearing ability in the prelingual deafness group before and after operation and the differences with the postlingual deafness group were compared, and the correlation between speech recognition ability and the age diagnosed as severe or profound deafness, the age of hearing aid invalid, and duration of wearing cochlear implant were analyzed as factor indicators. All statistical results were analyzed by SAS 9.4 software. Results: In terms of objective indicators, the speech recognition rate of pre-lingual deafness was significantly lower than that of post-lingual deafness [(35.4±28.0)% vs (80.9±8.0)%,t=7.67, P<0.001], while there was no statistical difference in hearing threshold between the two groups [(34.8±4.0) dB HL vs (33.1±3.7) dB HL, t=1.30, P>0.05]. The indicators in the subjective questionnaire showed that the prelingual deafness group was only weaker in advanced sound perception, confidence and total mean score than the post-lingual deafness group (P<0.05), and there was no significant difference in other aspects(P>0.05), meanwhile, all indicators of the prelingual deafness group were significantly improved compared with the preoperative level (P<0.001). There was a moderate positive correlation between the hearing quality and the speech recognition rate in the prelingual deafness group(r=0.51, P=0.008). The regression analysis showed that the invalid age of hearing aid was the exact influencing factor of speech recognition rate. Conclusions: Certain prelingual deaf adults can adapt to cochlear implants and obtain different degrees of auditory assistance. Compared with the improvement of objective auditory ability assessment, the patient who received cochlear implantation gain more improvement in auditory related quality of life subjectively. The ineffective age of preoperative hearing aid is an important factor, which needs to be aroused sufficient preoperative attention.

Treated with interferon and the gene polymorphism of CGRP and its receptor.

OBJECTIVE: This case-control study aims to investigate the relationship of polymorphisms of four gene loci (CGRP rs155209 and rs3781719, RAMP1 rs3754701 and rs7590387) with the prognosis of interferon therapy for chronic hepatitis B (CHB). MATERIALS AND METHODS: A total of 317 CHB patients receiving interferon alone for the first time were recruited in northern China, and peripheral blood samples were obtained. The single-nucleotide polymorphisms (SNPs) in rs155209, rs3781719, rs3754701, and rs7590387 were genotyped using Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS). Univariate and multivariate logistic regression methods were employed to assess the correlation between CHB prognosis treated with interferon and polymorphisms of these gene loci. RESULTS: The study clearly demonstrated the relevance of polymorphisms of rs155209, rs3781719, rs3754701, and rs7590387 with DNA response and ALT response after interferon treatment. CHB patients with CGRP rs155209C had a lower risk of developing DNA response (CT vs. TT: OR = 0.159, 95% CI = 0.086-0.294, Padj < 0.001; CC vs. TT: OR = 0.131, 95% CI = 0.059-0.288, Padj < 0.001), as well as a lower risk of developing ALT response (CT vs. TT: OR = 0.530, 95% CI = 0.323-0.869, Padj < 0.05). Moreover, CHB patients with RAMP1 rs3754701T allele were more prone to develop DNA response (AT vs. AA: OR = 2.061, 95% CI = 1.237-3.435, Padj < 0.05; TT vs. AA: OR = 5.676, 95% CI =1.247-25.837, Padj < 0.05), and they also more likely to develop ALT response (AT vs. AA: OR = 1.766, 95% CI = 1.098-2.840, Padj < 0.05). We did not find a significant association between CGRP rs3781719 or RAMP1 rs7590387 and DNA response or ALT response. CONCLUSION: This study revealed that CGRP rs155209 and RAMP1 rs3754701 polymorphisms, but not CGRP rs3781719 and RAMP1 rs7590387, were correlated with interferon therapy prognosis for CHB in Han Chinese population, and RAMP1 rs3754701T was a protective factor for ALT response and DNA response, but CGRP rs155209C carriers were less prone to DNA and ALT responses.

Immunogenicity and safety levels of inactivated quadrivalent influenza vaccine in healthy adults via meta-analysis.

Objective: The aim of the current study was to evaluate immunogenicity and safety levels of human inactivated quadrivalent influenza vaccine (QIV) which includes two A strains (A/H1N1, A/H3N2) and two B lineages (B/Victoria, B/Yamagata) in healthy adults via meta-analysis. Methods: Searches were conducted in PubMed, Cochrane Library, ClinicalTrials.gov, and EMBASE databases published in 2011-2020 according to inclusion and exclusion criteria. The purpose was to collect and perform meta-analysis of related randomized clinical trial (RCT) data concerning safety and immunogenicity levels of human QIV compared with inactivated trivalent influenza vaccine (TIV). Results: A total of 9 literatures were included. There was no significant difference in the seroconversion(SCR) and seroprotection(SPR) between QIV and TIV for influenza A strains (A/H1N1, A/H3N2) and the B lineage included in the TIV. QIV showed superior efficacy for the B lineage not included in the TIV: SCR RR of 2.20 (95%CI: 1.44-3.37, p = .0003) and SPR RR of 1.34 (95%CI: 1.10-1.63, p = .004) for B/Victoria, and SCR RR of 1.88 (95%CI: 1.53-2.31, p < .00001) and SPR RR of 1.11 (95%CI: 1.03-1.19, p = .006) for B/Yamagata, respectively. There were no significant differences between QIV and TIV for local and systemic adverse events(AE) post-vaccination. Conclusion: In adults 18-64 years old, QIV not only produced similar immunogenicity and safety levels to TIV, but also had better immunogenicity against influenza B vaccine strains not included in TIV.

Effect of Canine-assisted Therapy on Family Function of Autism Spectrum Disorder / 中国康复理论与实践

Objective:To evaluate the effect of canine-assisted therapy on family function of autism spectrum disorder. Methods:The randomized controlled trials (RCT) about the effect of canine-assisted therapy on family function of autism spectrum disorder were retrieved from the Cochrane Library, PubMed, Web of Science, CNKI, CBM, VIP, and Wanfang Data from establishment to February, 2021. Brief Family Assessment Measure-III-General Scale (FAM-III-GS) was used to access the family function, and Children's Depression Inventory-Second Edition (CDI-2) and Spence Children's Anxiety Scale (SCAS) were used to access the psychological behavior. The quality of included studies was evaluated according to the method recommended by the Cochrane Collaboration and Joanna Briggs Institute Reviewers' manual. RevMan 5.4 software was used for meta-analysis. Results:Finally, four RCTs involving 190 patients were included. There were too less RCTs to do a meta-analysis. Two RCTs showed that the score of FAM-III-GS improved in the experimental group than in the control group. Conclusion:Canine-assisted therapy might improve the family function of patients with autism spectrum disorder.

Effect of combined application of inorganic and organic fertilizers on growth and quality of Salvia miltiorrhiza / 中国中药杂志

The study is aimed through field experiments to study the effect of combined application of organic and chemical fertilizers on the growth and quality of Salvia miltiorrhiza, provide ideas for reducing fertilization while increasing the efficiency as well as improving the quality of produces. The experiment included 6 treatments viz., no fertilization(CK), full application of chemical fertilizer(F), 25% orga-nic fertilizer with 75% chemical fertilizer(M25), 50% organic fertilizer with 50% chemical fertilizer(M50), 75% organic fertilizer with 25% chemical fertilizer(M75), and fully apply organic fertilizer(M100). The results showed that:(1)from the perspective of yield and economic benefits, M75 was the best and M100 second;(2)for effective components, the combined application of organic and chemical fertilizers increased the content of main water-soluble components and the total content of effective components, among which M25 and M50 were better.
