ABSTRACT

Objective: To investigate the prospective association of physical activity with all-cause, cardiovascular disease (CVD), and chronic kidney disease (CKD) mortality in CKD patients in China. Methods: Cox proportional hazard models were used to evaluate the association of total, domain-specific, and intensity-specific physical activity with the risk of all-cause, CVD, and CKD mortality based on data from the baseline survey of China Kadoorie Biobank. Results: During a median follow-up of 11.99 (11.13, 13.03) years, there were 698 deaths in 6 676 CKD patients. Compared with the bottom tertile of total physical activity, participants in the top tertile had a lower risk of all-cause, CVD, and CKD mortality, with hazard ratios (HRs) (95%CIs) of 0.61 (0.47-0.80), 0.40 (0.25-0.65), and 0.25 (0.07-0.85), respectively. Occupational, commuting, and household physical activity were negatively associated with the risk of all-cause and CVD mortality to varying degrees. Participants in the top tertile of occupational physical activity had a lower risk of all-cause (HR=0.56, 95%CI: 0.38-0.82) and CVD (HR=0.39, 95%CI: 0.20-0.74) mortality, those in the top tertile of commuting physical activity had a lower risk of CVD mortality (HR=0.43, 95%CI: 0.22-0.84), and those in the top tertile of household physical activity had a lower risk of all-cause (HR=0.61, 95%CI: 0.45-0.82), CVD (HR=0.44, 95%CI: 0.26-0.76) and CKD (HR=0.03, 95%CI: 0.01-0.17) mortality, compared with the bottom tertile of corresponding physical activity. No association of leisure-time physical activity with mortality was observed. Both low and moderate-vigorous intensity physical activity were negatively associated with the risk of all-cause, CVD and CKD mortality. The corresponding HRs (95%CIs) were 0.64 (0.50-0.82), 0.42 (0.26-0.66) and 0.29 (0.10-0.83) in the top tertile of low intensity physical activity, and the corresponding HRs (95%CIs) were 0.63 (0.48-0.82), 0.39 (0.24-0.64) and 0.23 (0.07-0.73) in the top tertile of moderate-vigorous intensity physical activity. Conclusion: Physical activity can reduce the risk of all-cause, CVD, and CKD mortality in CKD patients.

ABSTRACT

Tumor metastasis depends on the dynamic balance of the actomyosin cytoskeleton. As a key component of actomyosin filaments, non-muscle myosin-IIA disassembly contributes to tumor cell spreading and migration. However, its regulatory mechanism in tumor migration and invasion is poorly understood. Here, we found that oncoprotein hepatitis B X-interacting protein (HBXIP) blocked the myosin-IIA assemble state promoting breast cancer cell migration. Mechanistically, mass spectrometry analysis, co-immunoprecipitation assay and GST-pull down assay proved that HBXIP directly interacted with the assembly-competent domain (ACD) of non-muscle heavy chain myosin-IIA (NMHC-IIA). The interaction was enhanced by NMHC-IIA S1916 phosphorylation via HBXIP-recruited protein kinase PKCβII. Moreover, HBXIP induced the transcription of PRKCB, encoding PKCβII, by coactivating Sp1, and triggered PKCβII kinase activity. Interestingly, RNA sequencing and mouse metastasis model indicated that the anti-hyperlipidemic drug bezafibrate (BZF) suppressed breast cancer metastasis via inhibiting PKCβII-mediated NMHC-IIA phosphorylation in vitro and in vivo. We reveal a novel mechanism by which HBXIP promotes myosin-IIA disassembly via interacting and phosphorylating NMHC-IIA, and BZF can serve as an effective anti-metastatic drug in breast cancer.

ABSTRACT

Objective:To explore the risk factors for the occurrence of thrombocytopenia (TCP) within 2 weeks after pediatric liver transplantation (LT) and examine the relationship between the occurrence of TCP and prognosis.Methods:From January 2021 to November 2021, clinical data were retrospectively reviewed for 162 pediatric LT recipients aged under 4 years at Organ Transplantation Center of Tianjin First Central Hospital.Based upon the lowest value of platelet count at Week 2 post-operation, they were assigned into two groups of TCP (n=90) and non-TCP (n=72). General preoperative profiles, intraoperative findings, postoperative complications, types of commonly used antibiotics, anticoagulant dosing and prognosis of two groups were compared.Univariate and multivariate analyses were utilized for examining the independent risk factors for TCP.Receiver operating characteristic (ROC) curve was plotted for examining the cut-off value of independent risk factors for diagnosing TCP.Results:Among them, 90 (55.56%) developed TCP within 2 weeks post-operation and 25(15.43%) developed TCP at Day 1 post-operation.The median preoperative platelet count was 178×10 9/L and the lowest value was 65×10 9/L at Day 3(1-4) post-operation with a declining rate of 63.5% and platelet count of recipient normalized at Day 6(4-7.25) post-operation.The results of univariate analysis showed statistically significant inter-group differences in operative duration[(574.43±80.53)min vs.(526.75±72.42)min], intraoperative blood loss[400(300, 550)ml vs.320(300, 400)ml], red blood cell transfusion[2(2, 3)U vs.2(1.5, 2.0)U], preoperative platelet count[178.5(141.75, 242.5)×10 9/L vs.257 (209.75, 357)×10 9/L], postoperative infection rate[27.8%(25/90)vs.13.9%(10/72)] and dosing rates of piperacillin sodium and tazobactam sodium[8.9%(8/90)vs.25.0%(18/72)] ( P<0.05). Multivariate Logistic regression analysis revealed statistically significant inter-group differences in operative duration( P=0.008), red blood cell transfusion( P=0.01), preoperative platelet count( P<0.01) and postoperative infection rate ( P=0.02). The results of ROC curve analysis showed that the cut-off values of operative duration, red blood cell transfusion and preoperative platelet count were 535 min, 2.75 U and 183.5×10 9/L respectively.Length of ICU stay was higher in TCP group than that in non-TCP group, and the difference was statistically significant [4(3, 5) vs.3(3, 4) day, P=0.006]. Conclusions:LT children aged under 4 years with intraoperative red blood cell transfusion>2.75 U, operative duration>535 min and preoperative platelet count<183.5×10 9/L are more likely to develop post-transplantation TCP.And occurrence of TCP prolongs the length of ICU stay in pediatric recipients.

ABSTRACT

Objective:To investigate the predictive value of the epithelial cell proliferation(ECP)pathway genes for the prognosis of elderly non-small cell lung cancer patients treated with immunotherapy.Methods:A total of 106 elderly patients aged 70 years and over receiving immunotherapy in the POPLAR and OAK clinical trials were retrospectively analyzed in October 2022.According to the mutation status, patients were divided into an ECP pathway-related gene mutation group(ECP mutation group, n=25)and an ECP pathway-related gene non-mutation group(ECP non-mutation group, n=81). The primary endpoints were overall survival(OS)and progression-free survival(PFS). Differences in survival and efficacy between the two groups were compared, and subgroup analysis was performed on clinical factors and genes involved in the pathway.Pyclone was used to calculate the distribution of major clones and subclones in each patient, and differences in survival were compared.Results:Survival outcomes were worse in the ECP(+ )group than in the ECP(-)group(mOS: 10.9 months vs.17.1 months, HR=1.84, 95% CI: 1.09-3.08, P<0.05; mPFS: 2.8 months vs.4.2 months, HR=1.58, 95% CI: 1.00-2.51, P<0.05). Of all mutations in ECP pathway-related genes, mutations in the RB1 gene had a significant prognostic effect on all patients, with the negative prognostic effect especially prominent in ECP(+ )patients.Compared with ECP(-)patients, ECP(+ )patients had a shorter mOS(6.9 months vs.12.6 months, HR=3.14, 95% CI: 1.10-8.97, P=0.024). Ten patients had clonal mutations and 15 patients had sub-clonal mutations in ECP pathway-related genes and the former had a shorter mPFS than the latter(1.3 months vs.5.3 months, HR=3.23, 95% CI: 1.25-8.37, P=0.011). Conclusions:Gene mutations in the epithelial cell proliferation pathway are a negative prognostic factor in elderly non-small cell lung cancer patients receiving immunotherapy, and mutations located in the clonal cluster have a stronger impact on the prognosis.

ABSTRACT

Objective:To analyze the status of the dyadic coping in spouses of young and middle-age cervical cancer patients undergoing synchronous radiotherapy and chemotherapy, and to explore the influencing factors in bi-directional of patients and their spouses.Methods:With the convenience sampling method, a total of 150 cervical cancer patients undergoing synchronous radiotherapy and chemotherapy who were hospitalized in the Radiotherapy Department of Tianjin Medical University Cancer Institute and Hospital from March 2021 to February 2022 and their spouses were selected. A cross-sectional study was conducted by the Dyadic Coping Inventory, the Lock-Wallace Marital Adjustment Test, the General Self-Efficacy Scale, the Hospital Anxiety and Depression Scale, etc. Besides, multiple linear regression was used to identify predictors of the dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy.Results:The total score of dyadic coping, marital quality, general self-efficacy, anxiety and depression in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (121.69 ± 19.67), (97.23 ± 25.05), (25.13 ± 5.19), (9.98 ± 3.46), (8.19 ± 4.06) points. The scores of anxiety and depression of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy were (10.57 ± 3.60), (9.10 ± 4.12) points. Multiple linear regression analysis showed that factors of the patients′ anxiety and depression, spouse′s perception of marital quality, spouse′s general self-efficacy, changes in family relationship, family income, and period of radiotherapy were the main influencing factors ( P<0.01), which accounted for 55.7% of total variation. Conclusions:The level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy was medium, the marriage quality remains to be further improved,and its influence factors involved in the bi-directional of patient and spouse, including patients′ anxiety and depression, the changes of the family relationship, period of radiotherapy, spouses perception of marital quality and self-efficacy and family income. Clinical medical staff can improve the level of dyadic coping in spouses of cervical cancer patients undergoing synchronous radiotherapy and chemotherapy by improving their cognition of disease, reducing the incongruence of dyadic illness appraisals, and taking multiple measures to reduce the economic burden felt of the spouses.

ABSTRACT

Objective:To explore the mechanism of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair in delaying heart aging based on animal experiments, network pharmacology and molecular docking. Methods:Mice were divided into control group, aging group, metformin group and TCM group according to random number table method. All the groups were injected subcutaneously by D-galactose except the control group to build the subacute aging model. Two weeks later, the metformin group was given metformin suspension (150 mg/kg), the TCM group was given Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma lyophilized powder solution (650 mg/kg), and the control group and aging group were given an equivalent volume of ultrapure water by gastric gavage, once a day, six times a week, for 10 weeks. The level of heart TERT mRNA was detected by PCR; the expression of heart p53 was observed by immunohistochemical staining; the morphology of heart tissue was observed by HE staining. TCMSP and SwissTargetPrediciton databases were used to retrieve the active components and targets of Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma medicinal pair; TTD, OMIM, Gene, HAGR, DisGeNET and other data platforms were used to screen the targets of heart aging; after the drug and disease targets were intersected, the active components of them were collected; STRING database, Cytoscape 3.8.0 software, etc. were used to make PPI of the intersection targets, and screen out the key targets; FunRich was used to perform enrichment analysis of cellular components, molecular functions, biological processes, and biological signal pathways for key targets; Schr?dinger Maestro software was used to do the molecular docking of the screened active components and key targets, and docking results were visualized via PyMOL 2.1 software. Results:Experiment results showed that Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma could significantly ameliorate the damage of aging heart tissues, elevate TERT mRNA level, while significantly reducing the positive expression of p53. A total of 32 active components from the medicinal pair were screened, corresponding to 637 target genes. There were 263 targets for heart aging, and 67 intersection targets of drug active component targets and heart aging targets. 31 key targets were obtained after screening. Enrichment analysis showed that molecular functions were related to transcription factor activity and protein-tyrosine kinase activity. Biological processes involved signal transduction and cell communication. Signaling pathways mainly involved PDGFR-beta, PI3K-Akt, S1P1, Glypican, TRAIL, and Glypican 1. The molecular docking results showed that kaempferol, suchilactone, and ginsenoside Rg5_qt in the medicinal pair had a strong binding ability to p53. Conclusion:Ginseng Radix et Rhizoma- Notoginseng Radix et Rhizoma- Chuanxiong Rhizoma may achieve the effect of delaying heart aging by inhibiting p53 expression, providing a foundation for further research on mechanism of invigorating qi and activating blood circulation drugs to delay heart aging.

ABSTRACT

MLL3 is also known as lysine methyltransferase 2C (KMT2C). The mutation of MLL3 can occur in a variety of human cancers, including leukemia, liver cancer, and stomach cancer. The effect of MLL3 in different cancers is also different, for example, MLL3 is carcinogenic in pancreatic and liver cancer, while it acts as a tumor suppressor in acute myeloid leukemia and esophageal squamous cell carcinoma. The effects of genes in tumors depend on certain environment and conditions, and the mechanism of the suppressive effect of MLL3 in leukemia is still not clear. This paper reviews the research progress of the antitumor mechanism of MLL3 in leukemia.

ABSTRACT

Pro-inflammatory macrophages play key regulatory role in the occurrence and development of rheumatoid arthritis (RA). In this study, we constructed a celastrol (Cel)-loaded polyamide-amine dendrimer (PAMAM) drug delivery system, which could target folate receptor and mitochondria. It could target inflammatory macrophages and realize chemo-photothermal synergistic therapy. Using PAMAM as the nano-carrier, folate receptor-targeting group folic acid (FA) and mitochondria-targeting group IR808 (also known as the photothermal agent) were conjugated with PAMAM through amide reaction, and then complexed with anti-inflammatory drug Cel to prepare the FA-PAMAM-IR808/Cel nanocomplex. In vitro characterization results showed that the drug loading efficiency of the nanocomplex was 50.90%, particle size was between 130 and 160 nm, average potential was between 1.0 and 3.5 mV, the drug release showed pH sensitivity, temperature reached to 42.5 ℃ after near-infrared (NIR) light irradiation for 10 min. In vitro cellular uptake experiments showed that the nanocomplex had obvious folate receptor-targeting and mitochondria-targeting ability. Following irradiation with NIR light, the cytotoxicity and cellular apoptosis enhanced. The secretion of pro-inflammatory factors tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6 and nitric oxide (NO) decreased in a concentration-dependent manner. This study provided insights for the development of novel anti-RA nanomedicines.

ABSTRACT

It is generally believed that high-quality Bupleurum scorzonerifolium roots possess specific morphological characteristics, being red, robust, and long with strong odor. However, the scientific connotation of these characteristics has not been elucidated. According to the theory of "quality evaluation through morphological identification", we studied the correlations between appearance traits(the RGB value of root surface, root length, root diameter, dry weight, and ratio of phloem to xylem) and content of main chemical components(volatile oils, total saponins, total flavonoids, total polysaccharides, and seven saikosaponins) of B. scorzonerifolium roots. Epson Scanner and ImageJ were used to scan the root samples and measure the appearance traits. Ultraviolet spectrophotometry and HPLC were employed to determine the content of chemical components. The correlation, regression, and cluster analyses were performed to study the correlations between the appearance traits and the content of chemical components. The results showed that the content of volatile oils and saikosaponins were significantly correlated with RGB value, root length, and root diameter, indicating that within a certain range, the roots being redder, longer, and thicker had higher content of volatile oils and saikosaponins. According to the appearance traits and chemical component content, the 14 samples from different producing areas were classified into four grades, and the differences in morphological traits and chemical component content were consistent among different grades. The findings in this study demonstrate that appearance traits(RGB value, root length, and root diameter) can be used to evaluate the quality of B. scorzonerifolium roots. Meanwhile, this study lays a foundation for establishing an objective quality evaluation method for B. scorzonerifolium roots.

ABSTRACT

OBJECTIVE To explore the material basis and potential mechanism of Kazakh classic prescription Wuzdekh (WZDK) in the treatment of enteritis. METHODS LC-MS/MS technology was used to analyze the chemical components in WZDK. Through network pharmacology and molecular docking technology, the main chemical components of WZDK were screened and the target was predicted; therapeutic effect and target of WZDK on acute enteritis were verified through in vivo experiments. The acute enteritis model of mice was induced by dextran sulfate sodium salt; the general condition of the mice was observed during administration and the disease activity index (DAI) score was calculated; pathological changes of the intestine and mRNA expression of core target were validated by HE staining and quantitative real-time PCR. RESULTS A total of 316 chemical components were obtained by LC-MS/MS. The core targets of network pharmacological analysis mainly included interleukin 1β(IL- 1β), protein kinase B1 (AKT1), tumor protein p53 (TP53), IL-6, tumor necrosis factor (TNF) and so on. The results of molecular docking showed that chemical components such as mairin, lappadilactone, costunolide and dehydrocostus lactone were stable in binding to the core target. The results of in vivo experiment showed that, compared with model group, high dose (5.00 g/kg) of WZDK could significantly reduce the DAI score (P<0.05), improve inflammatory cell infiltration and mucosal tissue damage of colon tissue, and significantly down-regulated mRNA expressions of IL-6, TNF-α, IL-1β and TP53 in colon tissue(P< 0.05 or P<0.01). CONCLUSIONS Chemical components of WZDK such as mairin, lappadilactone, costunolide and dehydrocostus lactone may play the role of improving the imbalance of local inflammatory factors in the intestine and repairing damage of colonic mucosal tissue by down-regulating mRNA expressions of TNF-α, IL-6, IL-1β and TP53 in colon tissue.

ABSTRACT

AIM: To compare the changes of optic disc parameters, peripapillary retinal nerve fibers layer(pRNFL)thickness and macular ganglion cell layer(mGCL)thickness among patients with early diabetes retinopathy and healthy controls by Cirrus HD-optical coherence tomography(OCT).METHODS: In this cross-sectional comparative study, 45 non-diabetic retinopathy(NDR), 52 mild nonproliferative diabetic retinopathy(NPDR), 55 moderate NPDR with type 2 diabetes mellitus(T2DM)and 64 age-matched healthy controls were included. The fasting blood glucose(FBG), duration of diabetes, glycosylated hemoglobin(HbA1c)and past history of the patients were collected in detail. Optic disc parameters(i.e., binocular RNFL thickness symmetry percentage, rim area, optic disc area, cup-to-disc ratio, cup volume), pRNFL thickness and mGCL thickness were measured by Cirrus HD-OCT. The comparison of different groups was performed by one-way analysis of variance.RESULTS: Compared with the control group, the binocular RNFL thickness symmetry percentage and rim area were significantly decreased, while the average C/D and vertical C/D were significantly increased in the NDR group, mild NPDR group and moderate NPDR group(all P&#x003C;0.05). Compared with the control group, the peripapillary RNFL thicknesses(superior, temporal, inferior, nasal)and macular GCL thickness(average, minimum, superior, supero-temporal, infero-temporal, inferior, supero-nasal, and infero-nasal)became thinner in the NDR group, mild NPDR group, and moderate NPDR group(all P&#x003C;0.05).CONCLUSION: Patients with early DR have significantly decreased binocular RNFL thickness asymmetry, rim area, pRNFL and mGCL thickness, while they have significantly increased cup-to-disc ratio when compared to healthy controls. The results support the statement that DM causes inner retinal neurodegenerative changes even in T2DM patients without overt microangiopathy.

ABSTRACT

Objective: To investigate the clinical effect of disk-up sinus reamer (DSR) in maxillary sinus floor elevation with maxillary sinus septum. Methods: Twenty-four patients were included between January 2019 to January 2020 in Department of Oral Implantology, The Affiliated Hospital of Qingdao University. There were 10 males and 14 females with the age of (39.3±11.7) years old (range 22-56 years). Pre-operative(T0) cone-beam CT (CBCT) was taken for measurement and analysis. All patients were divided into group E (easy situations, septum located anterior to the zygo-matic process), group M (moderate situations, septum located pos-terior to the zygo-matic process) and group D (difficult situations, sagittally oriented septum). The maxillary sinus floor was grafted through the crestal approach by DSR and implants were placed simultaneously. Permanent repair was performed 6-8 months after operation. All patients underwent CBCT before surgery, after surgery immediately (T1), 6 months after surgery(T2), 1 year after surgery(T3), 2 year after surgery(T4). The residual bone height (RBH) and the vertical bone height (VBH) were analyzed. The mucosal perforation rate, implant survival rate were counted. Results: All the 24 patients completed the Maxillary sinus lift surgery successfully and 24 implants were placed simultaneously. All patients had no headache, dizziness. The mucosal perforation rate was 0. The survival rate of implants during the healing period was 100%(24/24). The RBH was (5.81±2.56) mm pre-operation, the VBHT1, VBHT2, VBHT3 and VBHT4 were (11.82±1.09), (10.98±0.52), (10.66±0.44) and (10.40±0.33) mm, respectively. The differences between the groups by pairing test were statistically significant (F=187.70, P0.001), expect VBHT3 and VBHT4 (P=0.071). Bone resorption and remodeling mainly occurred 1 year after surgery. One patient developed peri-implantitis 18 months after surgery. Conclusions: With the RBH of implant site>2 mm and existence of maxillary sinus septum, using DSR for sinus floor elevation has a high success rate. It can obtain enough bone height and complete the simultaneous implantation to form a good osseointegration. The DSR is simple, safe and controllable, and can shorten the operation time.

ABSTRACT

Based on data mining technology, the acupoints compatibility rules of acupuncture for depression diseases were explored. The randomized controlled trial (RCT) articles regarding acupuncture for depression diseases published from establishment of database to September 2nd, 2022 were searched in CNKI database, Wangfang database, VIP database, SinoMed database, PubMed, EMbase, Web of Science and Cochrane Library. The use frequency of acupoints, meridian tropism, selection of special acupoints and acupoint association rules for five common depression diseases, including primary depression, post-stroke depression, menopausal syndrome, psychoneurosis and anxiety disorder, were analyzed by Python programming language. Cytoscape software was used to analyze the acupoint association and the disease-acupoint co-occurrence network. As a result, totally 387 articles were included, and 319 acupoints prescriptions for the above five common depression diseases were extracted, involving 159 acupoints. The use frequency of acupoints was 2 574 times in total. The frequently-used acupoints were Baihui (GV 20), Sanyinjiao (SP 6), Taichong (LR 3), Neiguan (PC 6), Shenmen (HT 7), Yintang (GV 24+), Zusanli (ST 36), Hegu (LI 4), Sishencong (EX-HN 1) and Taixi (KI 3), etc. The frequently involved meridians were the governor vessel, foot-taiyang bladder meridian, foot-taiyin spleen meridian, and foot-jueyin liver meridian. The frequency of the special acupoints from high to low was crossing points, five-shu points, yuan-primary points, back-shu points, luo-connecting points, and eight confluent points, etc, which were often used in combination with "Baihui (GV 20)-Yintang (GV 24+)" (the highest degree of association). At the same time, the analysis of the co-occurrence network of depression diseases and acupoints showed that the core acupoints group of acupuncture for depression diseases were Baihui (GV 20), Taichong (LR 3), Shenmen (HT 7), Zusanli (ST 36), Neiguan (PC 6) and Sanyinjiao (SP 6). In conclusion, acupuncture treatment for depression diseases has gradually formed a rule of acupoint compatibility, with special acupoint as the main body and "unblocking the governor vessel, and regulating the spirit and qi " as the main therapeutic principle.

ABSTRACT

Objective: To investigate the distribution of chronic kidney disease (CKD) in participants from the China Kadoorie Biobank (CKB) study and evaluate the association between lifestyle risk factors and CKD. Methods: Based on the baseline survey data and follow-up data (as of December 31, 2018) of the CKB study, the differences in CKD cases' area and population distributions were described. Cox proportional hazards regression model was used to estimate the association between lifestyle risk factors and the risk of CKD. Results: A total of 505 147 participants, 4 920 cases of CKD were recorded in 11.26 year follow up with a incidence rate of 83.43/100 000 person-years. Glomerulonephropathy was the most common type. The incidence of CKD was higher in the urban area, men, and the elderly aged 60 years and above (87.83/100 000 person-years, 86.37/100 000 person-years, and 132.06/100 000 person-years). Current male smokers had an increased risk for CKD compared with non-smokers or occasional smokers (HR=1.18, 95%CI: 1.05-1.31). The non-obese population was used as a control group, both general obesity determined by BMI (HR=1.19, 95%CI: 1.10-1.29) and central obesity determined by waist circumference (HR=1.27, 95%CI: 1.19-1.35) were associated with higher risk for CKD. Conclusion: The risks for CKD varied with area and population in the CKB cohort study, and the risk was influenced by multiple lifestyle factors.

ABSTRACT

Objective: To evaluate the household secondary attack rates of the SARS-CoV-2 Delta variant and the associated factors. Methods: A COVID-19 outbreak caused by the Delta variant occurred in Nanjing in July 2021. A total of 235 cases with current addresses in Nanjing were reported from 171 households. The subjects in this study were selected from household close contact(s) of infected cases. The information on household index cases and their contacts were collected, and the household secondary attack rate (HSAR) and the risk factors were analyzed by the multi-factor logistic regression model. Results: A total of 234 cases of household close contacts and 64 household secondary cases were reported from 103 households, and the HSAR was 27.4% (64/234, 95%CI:22.0% to 33.4%). The proportions of household size for 2 to 3, 4 to 5, and 6 to 9 were 64.1% (66), 26.2% (27) and 9.7% (10), respectively. A total of 35 cases of household cluster outbreaks were reported (35/103, 34.0%). The number of the first case in the household (FCH) was 103 and males accounted for 27.2% (28 cases), with the median age (Q1, Q3) of 49 (9, 56). The number of household close contacts was 234 and males accounted for 59.0% (138 cases), with the median age (Q1, Q3) of 42 (20, 55) and the median exposure period (Q1, Q3) of 3 (1, 3) days. The multi-factor logistic regression model showed that the higher HSAR was observed in the FCH with the features of airport staff (OR=2.913, 95%CI:1.469-5.774), detection from home quarantine screening (OR=6.795, 95%CI:1.761-26.219) and detection from mass screening (OR=4.239, 95%CI:1.098-16.368). Meanwhile, higher HSAR was observed in cases with longer household exposure (OR=1.221, 95%CI:1.040-1.432), non-vaccination (OR=2.963, 95%CI:1.288-6.813) and incomplete vaccinations (OR=2.842, 95%CI:0.925-8.731). Conclusion: The generation interval of the Delta variant is shortened, and the ability of transmission within the household is enhanced. In the outbreak in Nanjing, the associated factors of HSAR are occupation, detection route, vaccination and exposure period.

ABSTRACT

Ferroptosis is defined as an iron-dependent regulated form of cell death driven by lipid peroxidation. In the past decade, it has been implicated in the pathogenesis of various diseases that together involve almost every organ of the body, including various cancers, neurodegenerative diseases, cardiovascular diseases, lung diseases, liver diseases, kidney diseases, endocrine metabolic diseases, iron-overload-related diseases, orthopedic diseases and autoimmune diseases. Understanding the underlying molecular mechanisms of ferroptosis and its regulatory pathways could provide additional strategies for the management of these disease conditions. Indeed, there are an expanding number of studies suggesting that ferroptosis serves as a bona-fide target for the prevention and treatment of these diseases in relevant pre-clinical models. In this review, we summarize the progress in the research into ferroptosis and its regulatory mechanisms in human disease, while providing evidence in support of ferroptosis as a target for the treatment of these diseases. We also discuss our perspectives on the future directions in the targeting of ferroptosis in human disease.

ABSTRACT

OBJECTIVE@#To analyze the effect of CD56 expression on the prognosis of newly diagnosed multiple myeloma (MM) patients and explore the relationship between CD56 with clinical characteristics.@*METHODS@#In this retrospective study, the clinical data and laboratory parameters of 175 newly diagnosed MM patients from February 2015 to December 2020 in the Second Hospital of Anhui Medical University were collected. The patients were divided into CD56+ and CD56- groups based on the expression of CD56, and the general data and laboratory parameters of the two groups were compared. The patients were followed up to June 30, 2021, and progression-free survival (PFS) and overall survival (OS) were recorded. PFS and OS curves of the two groups were plotted respectively, and the survival differences were compared. Univariate and multivariate Cox regression analyses were performed to analyze the effect of CD56 on the prognosis of newly diagnosed MM patients.@*RESULTS@#In 175 newly diagnosed MM patients, 57(32.6%) cases were in the CD56-group and 118 (67.4%) cases in the CD56+ group. There was significant correlation between CD56 expression and ISS stage, ECOG score, platelets, β2-microglobulin, creatinine, and extramedullary disease (all P <0.05). The incidence of extramedullary disease in the CD56- group was significantly higher than that in the CD56+ group (29.8% vs 12.7%, P =0.006). The median follow-up time of the whole cohort was 23.6 (1.0-78.6) months. The median PFS of patients in CD56+ group and CD56- group were 18.6 (1.2-77.6) and 12.2 (1.0-49.0) months, respectively, and the median OS of the two groups were 27.6 (1.4-77.7) and 19.7 (1.0-78.6) months, respectively. The 2-year PFS rate in the CD56+ group was significantly higher than that in the CD56- group (57.6% vs 36.8%, P =0.010), and the 2-year OS rate in the CD56+ group was higher than that in the CD56- group, but it didn't reach statistical significance (74.6% vs 64.9%, P =0.158). The results of univariate Cox regression analysis showed that the PFS was significantly shorter in newly diagnosed MM patients with advanced age, type IgG, high ECOG score, decreased platelet count, increased lactate dehydrogenase level, extramedullary disease, and CD56- (all P <0.05), the OS was significantly shorter in patients with high ECOG score, decreased platelet count, increased lactate dehydrogenase level, extramedullary disease, and CD56- (all P <0.05). The results of multivariate Cox regression analysis showed that advanced age, type IgG, elevated lactate dehydrogenase level, extramedullary disease, and CD56- were independent prognostic factors for poor PFS (all P <0.05); and decreased platelet count, elevated lactate dehydrogenase level, and extramedullary disease were independent adverse prognostic factors for OS (all P <0.05), while there was no significant independent correlation between CD56 and OS (P >0.05).@*CONCLUSION@#Most of the newly diagnosed MM patients have positive expression of CD56. Loss of CD56 expression was associated with unfavorable biological and clinical parameters and poor prognosis, suggesting that CD56 has important clinical value in the prognosis of newly diagnosed MM patients.

ABSTRACT

OBJECTIVES@#To study the genetic characteristics, clinical characteristics, and prognosis of children with primary dilated cardiomyopathy (DCM).@*METHODS@#A retrospective analysis was performed on the medical data of 44 children who were diagnosed with DCM in Hebei Children's Hospital from July 2018 to February 2023. According to the genetic testing results, they were divided into two groups: gene mutation-positive group (n=17) and gene mutation-negative group (n=27). The two groups were compared in terms of clinical data at initial diagnosis and follow-up data.@*RESULTS@#Among the 44 children with DCM, there were 21 boys (48%) and 23 girls (52%). Respiratory symptoms including cough and shortness of breath were the most common symptom at initial diagnosis (34%, 15/44). The detection rate of gene mutations was 39% (17/44). There were no significant differences between the two groups in clinical characteristics, proportion of children with cardiac function grade Ⅲ or Ⅳ, brain natriuretic peptide levels, left ventricular ejection fraction, and left ventricular fractional shortening at initial diagnosis (P>0.05). The median follow-up time was 23 months, and 9 children (20%) died, including 8 children from the gene mutation-positive group, among whom 3 had TTN gene mutation, 2 had LMNA gene mutation, 2 had TAZ gene mutation, and 1 had ATAD3A gene mutation. The gene mutation-positive group had a significantly higher mortality rate than the gene mutation-negative group (P<0.05).@*CONCLUSIONS@#There is no correlation between the severity of DCM at initial diagnosis and gene mutations in children. However, children with gene mutations may have a poorer prognosis.
