ABSTRACT
Objective:To investigate the clinical phenotype and genetic variation of Basel-Vanagaite-Smirin-Yosef syndrome (BVSYS), and to enhance clinicians′ knowledge of the disease.Methods:The clinical data of a child with BVSYS admitted to the Department of Neurological Rehabilitation, Qingdao Women and Children′s Hospital Affiliated to Qingdao University in February 2023 were collected. Whole genome sequencing was used to analyze the pathogenic genes of the child, and Sanger sequencing was used to verify the suspected mutation sites of the family members. The clinical phenotype and genetic variation characteristics were analyzed, and the clinical characteristics of BVSYS were summarized in combination with relevant literature.Results:The patient, a female aged 3 years and 1 month, presented with global developmental delay, speech disorder, distinctive facial features, esotropia, epilepsy, hypotonia and atrial septal defect. Brain magnetic resonance imaging revealed bilateral ventriculomegaly with abnormal signal intensity in the posterior bodies of both lateral ventricles and thinning of the corpus callosum. The whole genome sequencing revealed a homozygous missense mutation c.518 (exon5) T>C (p.IIe173Thr) in the MED25 gene of the child, and Sanger sequencing confirmed that her parents and elder brother carried the aforementioned heterozygous mutation, which was classified as a likely pathogenic mutation according to the guidelines of the American College of Medical Genetics and Genomics. A total of 22 cases from 6 literature sources were retrieved, with no reported cases in China so far. Conclusions:BVSYS is clinically rare. For patients presenting with unexplained global developmental delay or intellectual disability combined with craniofacial, neurological, cardiac, and eye abnormalities, targeted genetic testing can facilitate a definite diagnosis.
ABSTRACT
Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.
ABSTRACT
Objective:To investigate the clinical features of patients with maintenance hemodialysis (MHD) infected with SARS-CoV-2 and analyze the risk factors of death after SARS-CoV-2 infection, and to provide clinical data for early detection of critically ill patients and timely intervention.Methods:It was a cross-sectional investigation study. MHD patients in the hemodialysis centers of four tertiary hospitals with geographical representation in Shanxi province from December 1, 2022 to January 31, 2023 were enrolled, and the demographic data, dialysis-related indicators, laboratory test results and clinical features of SARS-CoV-2 infection were collected by distributing the questionnaires on SARS-CoV-2 infection, and consulting the hospital medical record system and the outpatient hemodialysis information system. SARS-CoV-2-infected patients were divided into survival group and death group according to whether all-cause death occurred and the differences of baseline data between the two groups were compared. Multivariate logistic regression analysis method was used to analyze the risk factors of mortality in MHD patients infected with SARS-CoV-2.Results:A total of 519 MHD patients were included in this study, with 508 patients (97.88%) infected with SARS-CoV-2, 474 patients in the survival group and 34 patients in the death group. The clinical symptoms of MHD patients infected with SARS-CoV-2 were diverse, and the most common initial symptom was fever (314/508, 61.81%). Other initial symptoms included cough and phlegm in 66 patients (12.99%), fatigue in 66 patients (12.99%), poor appetite in 20 patients (3.94%), dyspnea in 20 patients (3.94%), muscle pain in 14 patients (2.76%) and diarrhea in 8 patients (1.57%). Compared with the survival group, the death group had older age ( t=5.229, P<0.001), high proportions of males ( χ2=12.319, P<0.001) and diabetic nephropathy ( χ2=49.423, P<0.001), and lower levels of red blood cells ( t=-5.060, P<0.001), lymphocyte ( t=-2.614, P=0.011), neutrophil ( t=-5.117, P<0.001), serum albumin ( t=-2.940, P=0.012), serum prealbumin ( t=-3.519, P=0.001), blood phosphorus ( t=-3.309, P=0.002), serum creatinine ( Z=-3.607, P<0.001), total triglyceride ( Z=-2.486, P=0.013), total cholesterol ( Z=-3.291, P=0.001) and low-density lipoprotein cholesterol ( Z=-3.292, P=0.001). Among 508 SARS-CoV-2-infected patients, 194 patients (38.19%) were treated with nonsteroidal anti-inflammatory agents, 154 patients (30.31%) were treated with antibiotics, and 98 patients (19.29%) were treated with antiviral drugs. There were 225 (43.29%) vaccinated patients against SARS-CoV-2. Multivariate logistic regression analysis showed that low red blood cells ( OR=0.256, 95% CI 0.014-0.429), low lymphocytes ( OR=0.487, 95% CI 0.193-0.826), low serum albumin ( OR=0.613, 95% CI 0.329-0.917), older age ( OR=1.227, 95% CI 1.066-1.412) and diabetes mellitus ( OR=1.126, 95% CI 1.025-1.235) were the independent influencing factors of all-cause mortality in MHD patients infected with SARS-CoV-2. Conclusions:The clinical manifestations of SARS-CoV-2 infection in MHD patients are varied. Low red blood cells, low lymphocytes, low serum albumin, elder age and diabetes mellitus are the independent risk factors of death after SARS-CoV-2 infection in MHD patients. Strengthening management of MHD patients especially in the elderly, and improving and correcting anemia and malnutrition in time, may reduce the death risk of SARS-CoV-2 infection in MHD patients.
ABSTRACT
ObjectiveTo observe the clinical efficacy of Tongdu Huoxue decoction in the treatment of acute lumbar disc herniation (LDH). MethodA total of 316 patients with acute LDH admitted to the orthopedic outpatient department of Hubei Provincial Hospital of Traditional Chinese Medicine and Honghu City Hospital of Traditional Chinese Medicine from January 2020 to June 2023 were randomly divided into two groups. 156 cases in the control group (two cases with stopped follow-up) were treated with meloxicam tablets, while 153 cases in the observation group (five cases with stopped follow-up) were treated with Tongdu Huoxue decoction. Both groups were treated for three months. The clinical efficacy, McGill Pain Score Scale (SF-MPQ), Oswestry Dysfunction Index (ODI) score, and the Japanese Orthopaedic Association (JOA) scores of the two groups before and after treatment were compared. The serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) of the patients before and after treatment were determined by using enzyme-linked immunosorbent assay (ELISA). The NDI-092 type electromyography-evoked potential instrument was adopted to measure the motor conduction velocity and clinical efficacy of the tibial and common peroneal nerves in patients of the two groups before and after treatment, and the clinical safety of the two groups of patients was compared. ResultAfter treatment, the total effective rate in the observation group was 95.4% (146/153), significantly higher than that in the control group of 76.3% (119/156) (χ2 =23.18, P<0.05). After treatment, both groups showed significant reductions in SF-MPQ and ODI scores, as well as the levels of IL-1β, IL-6, and TNF-α (P<0.05), with the observation group showing a more significant reduction (P<0.05). Both groups showed a significant increase in JOA scores and motor conduction velocities of the tibial and common peroneal nerves after treatment (P<0.05), with the observation group showing a more significant increase (P<0.05). ConclusionTongdu Huoxue decoction can alleviate lumbar and leg pain in acute LDH, improve lumbar spine function, and suppress inflammatory reactions. It is highly safe and is worthy of clinical promotion.
ABSTRACT
As a new hypoglycemic drug,Dapagliflozin has attracted much attention because of its unique hypoglycemic mechanism. It has been used in many studies on type 2 diabetes mellitus,but the application of type 1 diabetes mellitus(T1DM)in the eastern population is rare. This article uses Dapagliflozin through a case of obese T1DM to provide new ideas for the treatment of T1DM.
ABSTRACT
Objective:To explore clinical factors of poor prognosis in patients with anti-melanoma differentiation-associated gene 5 andtibody positive dermatomyositis (MDA5-DM).Methods:One hundred and twenty-six enrolled adults with MDA5-DM were divided into the survival group and the deceased group according to the outcomes. Survival time, clinical manifestations, laboratory tests, pulmonary function tests, myositis antibodies and treatments were collected for statistical analysis. Serum concentrations of IL-15, HMGB1, and sCD163 were measured by ELISA in MDA5-DM patients and healthy controls. Mann-Whitney U nonparametric test and Student′s t-test were used to compare the continuous variables between the two groups, and χ2 or Fisher′s exact test were used for comparison of categorical variables. Cox regression analysis was used to assess the survival predictors in MDA5-DM patients. The cumulative survival rate was calculated by Kaplan-Meier curve analysis, and Log-rank tests were used to examine differences in survival curves. P<0.05 was considered statistically significant. Results:Cox multivariate regression analysis revealed that age > 57 years [ HR (95% CI)=3.05 (1.20, 7.80), P=0.020], RP-ILD [ HR (95% CI)=25.07 (5.42, 115.98), P<0.001], and levels of anti-Ro52 antibody [ HR (95% CI)=3.41 (1.36, 8.53), P=0.009] were important prognostic factors independent of multiple clinical parameters. The ELISA test results showed that the levels of serum IL-15[0.91 (0.66, 2.00)pg/ml vs. 0.51(0.39, 0.72)pg/ml, Z=-4.57, P<0.001] and HMGB1 [230.53(90.40, 394.31)ng/ml vs. 32.66 (17.82, 46.21)ng/ml, Z=-6.52, P<0.001] in MDA5-DM patients were significantly higher than those in healthy controls, but there were no significant differences in the level of serum IL-15 [1.21(0.63, 2.12)pg/ml vs. 0.91(0.68, 1.66)pg/ml, Z=-0.30, P=0.766], HMGB1[267.61(167.03, 444.23)ng/ml vs. 228.35(74.74, 344.32)ng/ml, Z=0.82, P=0.413], and sCD163 [112.70(93.45, 148.51)ng/ml vs. 132.72(96.79, 203.18)ng/ml, Z=-0.62, P=0.536] between the survival group and the deceased group. Conclusion:Older age, RP-ILD, and high levels of anti-Ro52 antibody significantly increase the risk of death in MDA5-DM patients. Intensive follow-up of patients with the above factors in the early stages may help to improve the prognosis.
ABSTRACT
Fusobacterium nucleatum (F. nucleatum) is an early pathogenic colonizer in periodontitis, but the host response to infection with this pathogen remains unclear. In this study, we built an F. nucleatum infectious model with human periodontal ligament stem cells (PDLSCs) and showed that F. nucleatum could inhibit proliferation, and facilitate apoptosis, ferroptosis, and inflammatory cytokine production in a dose-dependent manner. The F. nucleatum adhesin FadA acted as a proinflammatory virulence factor and increased the expression of interleukin(IL)-1β, IL-6 and IL-8. Further study showed that FadA could bind with PEBP1 to activate the Raf1-MAPK and IKK-NF-κB signaling pathways. Time-course RNA-sequencing analyses showed the cascade of gene activation process in PDLSCs with increasing durations of F. nucleatum infection. NFκB1 and NFκB2 upregulated after 3 h of F. nucleatum-infection, and the inflammatory-related genes in the NF-κB signaling pathway were serially elevated with time. Using computational drug repositioning analysis, we predicted and validated that two potential drugs (piperlongumine and fisetin) could attenuate the negative effects of F. nucleatum-infection. Collectively, this study unveils the potential pathogenic mechanisms of F. nucleatum and the host inflammatory response at the early stage of F. nucleatum infection.

Objective:To investigate the prevalence of thyroid nodules (TN) among people undergoing physical examination in Taiyuan City, and evaluate the impact of hyperuricemia (HUA) on the risk of TN.Methods:Using a prospective design, a total of 42 966 people who underwent routine physical examination at Shanxi Shangning Health Examination Center from October 2020 to October 2021 were selected as subjects and divided into the HUA group ( n = 7 235) and the non-HUA group ( n = 35 731) based on the serum uric acid levels. The propensity score matching (PSM) method was used to balance the confounding factors between groups, and logistic regression was used to analyze the impact of HUA on the risk of TN. Results:The total detection rate of TN in the physical examination population was 55.6% (23 907/42 966). The detection rate of TN in females [61.0% (15 011/24 618)] was higher than that in males [48.5% (8 896/18 348)], and the difference was statistically significant (χ 2 = 664.55, P < 0.001). A total of 2 438 pairs of matching data were obtained after PSM, and the distribution of confounding factors in HUA and non-HUA groups reached equilibrium (the absolute values of standardized differences < 0.10). Logistic regression analysis before PSM showed that HUA was a protective factor for the incidence of TN in general population and males [odds ratio ( OR) = 0.696, 0.817, 95% confidence interval ( CI): 0.661 - 0.732, 0.768 - 0.868], while HUA was a risk factor for the incidence of TN in females ( OR = 1.370, 95% CI: 1.192 - 1.574). After PSM, HUA was not a influencing factor for the incidence of TN in general population and males ( P > 0.05), but it was still a risk factor in females for the onset of TN ( OR = 1.373, 95% CI: 1.014 - 1.858). Conclusion:In the physical examination population in Taiyuan City, HUA is an independent risk factor for TN in females.
ABSTRACT
Objective:To systematically evaluate the effects of protein restriction, low-sodium diet and alkaline diet on renal outcomes, the rate of change in estimated glomerular filtration rate (eGFR) and all-cause mortality in chronic kidney disease (CKD) patients.Methods:Three main databases, Ovid, EMBASE and the Cochrane Library database, were searched for randomized controlled trials about the effects of protein restriction, alkaline diet, low-sodium diet in chronic kidney disease. The primary outcome was renal composite endpoint events, the annual rate of change in eGFR and all-cause mortality. Renal composite endpoint events was defined as >25% or 50% decrease from baseline in eGFR, doubling of serum creatinine, or the development of end-stage renal diseaseas during follow-up.The studies were selected according to inclusion and exclusion criteria and assessed for quality using Jadad Scale. Two investigators were chosen to search, extract and evaluate the data independently. Software Stata 16.0 and RevMan 5.4 were used for meta-analysis.Results:A total of 34 studies with 5 589 participants were included. Protein restriction ( RR = 0.78, 95% CI: 0.64 to 0.96, P < 0.001), alkaline diet ( RR = 0.64, 95% CI: 0.43 to 0.98, P < 0.001) and low-sodium diet ( RR = 0.45, 95% CI: 0.28 to 0.73, P < 0.01) reduced the risk of renal composite outcomes. Protein restriction ( MD = 1.85, 95% CI: 0.77 to 2.93, P = 0.001), alkaline diet ( MD = 1.45, 95% CI: 0.53 to 2.37, P < 0.001) and low-sodium diet ( MD = 1.84, 95% CI: 1.06 to 2.63, P < 0.001) also decreased the rate of delince in eGFR. But these dietary patterns did not show a clear beneficial effect for all-cause mortality ( RR = 1.15, 95% CI: 0.76 to 1.73, P = 0.167 for protein restriction, RR = 0.96, 95% CI: 0.31 to 3.02, P = 0.546 for alkaline diet and RR = 0.82, 95% CI: 0.48 to 1.40, P = 0.057 for low-sodium diet). Conclusion:The three dietary interventions may decline the rate of renal function exacerbation and decrease the risk of unfavourable renal outcomes in CKD patients, while have no clear beneficial effect on all-cause mortality.
ABSTRACT
Objective:To investigate the effects of fractional CO 2 laser, focused ultrasound and simple drug treatment of gynecological vulva white lesions. Methods:A prospective study was conducted on 126 patients with white lesions of the vulva admitted to Hainan Cancer Hospital from August 2018 to December 2020. They were divided into drug group, focused ultrasound group and fractional CO 2 laser group by random number table method, with 42 patients in each group. The drug group was treated with mometasone furoate cream or dexamethasone acetate cream, and the focused ultrasound group was treated with focused ultrasound; the fractional CO 2 laser group was treated with fractional CO 2 laser. The serum interleukin-2 (IL-2), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and human epidermal growth factor (EGF) levels before and after treatment, and Visual Analogue Scale (VAS) and Dermatology Life Quality Index (DLQI) scores of the three groups were compared. Results:Before treatment, there was no significant difference in the levels of IL-2, TNF-α, CRP and EGF among the three groups (all P>0.05). After treatment, the levels of IL-2, TNF-α, CRP and EGF in the three groups were significantly decreased, and the levels of IL-2, TNF-α, CRP and EGF in the focused ultrasound group and fractional CO 2 laser group were lower than those in the drug group, with statistically significant difference (all P<0.05). Before treatment, there was no significant difference in the white lesions, dry pruritus, sexual pain and chapped skin scores of the three groups (all P>0.05); After treatment, scores of all dimensions of the three groups were significantly decreased, and scores of all dimensions of the focused ultrasound group and fractional CO 2 laser were lower than those of the drug group, with statistical significance (all P<0.05). Before treatment, there was no significant difference in the scores of symptoms and feelings, daily activities and interpersonal relationship of the three groups (all P>0.05); After treatment, scores of all dimensions of the three groups were significantly decreased, and scores of all dimensions of the focused ultrasound group and fractional CO 2 laser were lower than those of the drug group, with statistical significance (all P<0.05). Conclusions:Fractional CO 2 laser has a remarkable effect in the treatment of gynecological vulva white lesions, which can reduce the level of inflammatory factors in patients, improve the pain condition, and improve the quality of life.
ABSTRACT
Objective:To explore the status of coronavirus disease 2019 (COVID-19) vaccines, safety and the influencing factors of adverse reactions in maintenance hemodialysis (MHD) patients.Methods:The study was a retrospective study. The MHD patients vaccinated with COVID-19 vaccines in Tianjin city from January 2020 to July 2022 were enrolled in the study. The data of general information, vaccination situation, adverse reactions, and laboratory tests before and after vaccination were collected. Logistic regression analysis was used to analyze the risk factors of adverse reactions after vaccination.Results:A total of 7 375 patients were registered to receive hemodialysis treatment in Tianjin city, of whom 1 036 patients (14.05%) vaccinated with COVID-19 vaccines were enrolled from 53 hemodialysis centers in the study, with age of (54.00±13.27) years old (17-88 years old), and 676 males (65.25%). There were 171 patients (16.51%) receiving the first dose of vaccines only, 464 patients (44.79%) receiving two doses of vaccines, 401 patients (38.71%) receiving three doses of vaccines, and 67 patients (6.47%) had adverse reactions. No serious adverse reaction occurred. The number of neutrophils after vaccination was lower than that before vaccination ( P < 0.05), while the number of lymphocytes, alanine aminotransferase, glutamic oxaloacetic aminotransferase, and serum albumin after vaccination were higher than those before vaccination (all P < 0.05). Logistic regression analysis showed that age ( OR=0.967, 95% CI 0.946-0.990, P=0.005), previous allergic history ( OR=0.013, 95% CI 0.001-0.151, P < 0.001), serum uric acid ( OR=1.004, 95% CI 1.001-1.008, P=0.020), numbers of vaccinations administered ( OR=0.505, 95% CI 0.330-0.774, P=0.002), leukocytes ( OR=0.766, 95% CI 0.628-0.935, P=0.009) and lymphocytes ( OR=0.082, 95% CI 0.045-0.148, P < 0.001) were independently correlated with the incidence of adverse reactions. Conclusions:The proportion of MHD patients vaccinated with COVID-19 vaccines is 14.05%. The incidence of adverse reactions is 6.47%, and there is no serious adverse reaction. Age, previous allergic history, serum uric acid, and numbers of vaccinations administered, leukocytes and lymphocytes are independently correlated with the incidence of adverse reactions in MHD patients.

ABSTRACT
Objective:To explore the clinical efficacy of ultrasound-indicated cervical cerclage in twin pregnancies.Methods:This retrospective cohort study included 96 asymptomatic twin pregnancies with cervix length (CL)≤2.5 cm at 16-27 +6 weeks indicated by transvaginal ultrasound from January 2013 to May 2022 in Fujian Maternity and Child Health Hospital. They received either cervical cerclage (cerclage group, n=45) or conservative treatment (conservative group, n=51). The subgroup analysis was further performed after stratifying the subjects into the CL≤1.0 cm subgroup, the CL>1.0-≤1.5 cm subgroup, and the CL>1.5 cm subgroup. Two independent samples t-test, Mann-Whitney U test, and Chi-square test were used to compare the differences in the pregnancy and perinatal outcomes between different groups. Multivariate logistic regression was used to analyze the impact of cervical cerclage on pregnancy outcomes of women with different CLs. Results:The average gestational age at delivery and the prolonged gestation were significantly greater in the cerclage group than those in the conservative group [35.9 (34.9-37.0) weeks vs 34.9 (29.1-36.1) weeks; 10.7 (9.6-13.1) weeks vs 8.7 (4.8-11.0) weeks, Z=-2.59 and -3.63, both P<0.05]. The incidences of preterm birth before 34 weeks and 28 weeks, chorioamnionitis, and preterm premature rupture of membrane were lower in the cerclage group than those in the conservative group [17.8% (8/45) vs 45.1% (23/51), χ2=8.16; 2.2% (1/45) vs 15.7% (8/51), Fisher' exact test; 8.9% (4/45) vs 25.5% (13/51), χ2=4.52; 15.6% (7/45) vs 33.3% (17/51), χ2=4.03; all P<0.05]. There were no statistically significant differences in the proportion of postpartum hemorrhage and live births between the two groups (both P>0.05). In the women with CL≤1.0 cm, the cerclage group had a greater gestational age at delivery [36.0 (34.8-37.3) weeks vs 34.9 (28.6-35.4) weeks, Z=-2.61, P=0.009], greater prolonged gestation [12.3 (9.7-13.9) weeks vs 7.3 (3.4-9.1) weeks, Z=-3.34, P=0.001], higher birthweight [2 430.0 (2 173.8-2 646.3) g vs 1 900.0 (1 372.5-2 435.0) g, Z=-3.06, P=0.002], lower incidence of adverse neonatal outcomes [16.7% (6/36) vs 36.7% (11/30), χ2=4.22, P=0.048] compared with the conservative group. Multivariate Logistic regression analysis showed that cerclage reduced the risks of preterm birth before 34 and 32 weeks [ aOR (95% CI)=0.083 (0.009-0.790) and 0.092 (0.009-0.939), both P<0.05]. However, cerclage did not reduce the risk of preterm birth in women with CL>1.5 cm or CL>1.0-≤1.5 cm (both P>0.05). Conclusion:Ultrasound- indicated cervical cerclage can reduce the risk of preterm birth before 34 and 32 weeks, prolong pregnancy, and improve perinatal outcomes in asymptomatic twin pregnancies with CL≤1.0 cm.
ABSTRACT
Objective:To investigate the expression of long non-coding RNA (lncRNA) MTATP6P1 in melanoma and its effect on the proliferation, migration and invasion of melanoma cells by targeting miRNA-411-5p (miR-411-5p).Methods:A total of 461 samples of melanoma tissues and paracancerous tissues (>2 cm from the tumor margin) were collected from the tumor-associated lncRNA database (TANRIC database updated in July 2021), and the expression of MTATP6P1 was compared between the two groups. The bioinformatics software lncRNA Disease v2.0 was used to predict the possible binding site microRNA (miRNA) of MTATP6P1. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression level of MTATP6P1 in melanoma cells A-375, WM266-4, VMM5A, A2058 and normal human epidermal melanocytes PIG1; and the lowest relative expression level of cells in MTATP6P1 were divided into MTATP6P1 group (transfected with MTATP6P1 overexpression plasmid) and NC group (transfected with blank plasmid). The proliferation ability of A-375 cells was detected by using CCK-8 method; the migration ability of A-375 cells was detected by using scratch test; the invasion ability of A-375 cells was detected by using Transwell assay; the targeting relationship between MTATP6P1 and miR-411-5p was detected by using dual luciferase reporter gene assay; Western blot was used to detect the expression of ERK signaling pathway related proteins in cells.Results:The relative expression levels of MTATP6P1 in melanoma tissues and adjacent tissues were 9.82±0.58 and 11.56±0.16, respectively. The expression level of MTATP6P1 in melanoma tissues was lower than that in paracancerous tissues ( t = 9.56, P = 0.009). The relative expression levels of MTATP6P1 in normal human epidermal melanocyte PIG1 and melanoma cells A-375, WM266-4, VMM5A, and A2058 were 1.01±0.13, 0.12±0.02, 0.66±0.04, 0.39±0.07, 0.49±0.05; the relative expression level of MTATP6P1 in melanoma cells was lower than that in PIG1 cells (all P < 0.05), and then A-375 cells with the lowest relative expression level were taken to perform the subsequent experiments. The relative expression levels of MTATP6P1 in A-375 cells of MTATP6P1 group and NC group were 14.83±1.67 and 1.02±0.30, respectively ( t = 8.13, P < 0.001). After 16, 24, 32, and 40 h of culture, the proliferation ability of the cells in the MTATP6P1 group was lower than that in NC group (all P < 0.05). The scratch healing rates of A-375 cells in MTATP6P1 group and NC group were (26±7)% and (55±4)%, respectively; the scratch healing rate in MTATP6P1 group was lower than that in NC group ( t = 3.48, P = 0.009). The invasive number of A-375 cells in MTATP6P1 group and NC group were (32±12) and (116±17), respectively; the number of invasive cells in MTATP6P1 group was lower than that in NC group ( t = 4.11, P = 0.006). The results of dual luciferase reporter gene assay showed that there was a targeting relationship between MTATP6P1 and miR-411-5p. The relative expression level of miR-411-5p in A-375 cells of MTATP6P1 group and NC group was 1.04±0.16 and 5.37±0.68, respectively; the expression level of miR-411-5p in MTATP6P1 group was lower than that in NC group ( t = 6.20, P < 0.001). The expressions of ERK signaling pathway proteins p-Ras, p-Raf, p-MEK1, p-RSK, and AP-1 in A-375 cells of MTATP6P1 group were lower than those in NC group. Conclusions:MTATP6P1 inhibits the proliferation, migration and invasion of melanoma A-375 cells through targeting miR-411-5p.
ABSTRACT
Objective To evaluate the effect of the current immunization strategy for hepatitis B virus (Hepatitis B) in blocking mother-to-infant transmission in Hubei Province, and to explore the mechanism and possible influencing factors of failure of mother-to-infant blockade. Methods A multi-stage random sampling method was used to select 2 counties or districts in Hubei Province. Through maternity hospital health handbook, neonatal health record or hospital medical record system, hepatitis B virus (HBV) surface antigen (HBsAg)-positive pregnant women in 2012-2018 years were included to retrospectively investigate their delivery status and the HBV infection status of their children. Results Among the 302 newborns, 32 were positive for HBsAg, and the success rate of blockade of mother-to-infant transmission of hepatitis B was 89.45%. Further analysis showed that 68.21% (206 / 302) of newborns were delivered in township hospitals, 66.23% (200 / 302) were delivered by caesarean section and 41.72% (126 / 302) were breastfed, while 16.89% (51/302) were positive for hepatitis B virus e antigen (HBeAg), and 41.06% (124/302) were positive for anti-HBe. The vaccination rate of hepatitis B immunoglobulin (HBIG) during pregnancy was 3.31% (10/302), and the newborn HBIG vaccination rate was 94.37% (285/302). There were 84.11% (254/302) of pregnant women taking protective measures in daily life. Logistic regression analysis showed that township hospitals (OR=2.82, P<0.05), HBeAg positivity during pregnancy (OR=8.68, P<0.05), and HBIG vaccination during pregnancy (OR=12.62 , P<0.05) were risk factors for failure of mother-to-infant blockade, while anti-HBe positivity during pregnancy (OR=0.22, P<0.05), vaccination of newborns with HBIG (OR=0.20, P<0.05), and protective measures taken in daily life (OR=0.28, P<0.05) were protective factors for mother-to-infant interruption. Conclusion Deliveries in township hospitals and HBeAg-positivity during pregnancy are more likely to fail in blocking of mother-to-infant transmission of hepatitis B. HBIG vaccination during pregnancy does not reduce the risk of blockade failure. Neonatal HBIG vaccination, anti-HBe positivity during pregnancy, and protective measures in daily life can reduce the risk of blockade failure of mother-to-infant transmission of hepatitis B.

ABSTRACT
Objective:To assess two methods for peritoneal dialysis catheter removal in elderly patients on peritoneal dialysis.Methods:A retrospective cohort study was conducted and clinical data were collected for 107 elderly patients on peritoneal dialysis with catheters removed at the peritoneal dialysis center of the Second Hospital of Shanxi Medical University from August 2010 to May 2020.The 107 patients were divided into the open surgical extubation group and the 'pull' technique group.Sex, age, disease leading to dialysis, dialysis age, reason for extubation and preoperative test results were compared between the two groups.Operative time, length of postoperative hospitalization, perioperative pain and postoperative complications of the two groups were examined.Results:Higher levels or values were observed in operative time[(71.2±13.4)min vs.(19.3±5.6)min, t=16.933, P<0.01], length of postoperative hospitalization[(9.5±1.8)d vs.(2.2±0.5)d, t=10.988, P<0.01]and intraoperative pain score(4.4±1.6 vs.1.4±1.1, t=6.909, P<0.01)and pain score 24h after surgery(3.7±1.4 vs.0.5±0.3, t=9.995, P<0.01)in the open surgical extubation group than in the 'pull' technique group, but there was no statistical difference in the incidence of postoperative complications between the two groups(6.8% vs.5.0%, χ2=0.037, P>0.05). Conclusions:either the open surgical removal method or 'pull' technique.can safely and effectively remove the peritoneal dialysis catheter in elderly patients on peritoneal dialysis of the two methods, the 'pull' technique has advantages including less trauma, shorter and simpler surgery, helping achieve improved quality of life for elderly patients on peritoneal dialysis.
ABSTRACT
Acute intermittent porphyria(AIP) is a rare inherited metabolic disease that can cause severe and fatal acute attacks. This article shares the treatment and management of a severe AIP patient. It is proposed that (1) avoiding incentives is essential; (2) emotional problems easily overlooked should be paid attention; (3) long-term follow-up and patient education can improve the prognosis. The patient underwent renal biopsy during the remission period. We found a red-brown-yellow-white refractive index crystal under a polarized light microscope that had not been reported in the previous literature, which was speculated to be a porphyrin crystal.
ABSTRACT
Objective:Rat osteoarthritis (OA) model with different experimental cycles was established, analysis of small molecule metabolites in urine were carried out, in order to study the OA biomarkers and/or biomarker clusters with disease and/or the severity of disease indicator function.Methods:Using random number table method, sixty male SPF sprague-dawley (SD) rats weighing 300 - 350 g were randomly divided into model group and control group according to their body weights with 30 rats in each group. The experimental cycles were 4, 8 and 12 weeks, respectively. Rat OA model was established by modified Hulth method. At the end of each experiment, knee joint tissue and urine samples were collected. The knee joint histopathological slides were used to observe modeling situation under light microscope. High performance liquid chromatography quadrupole ion trap tandem mass spectrometer [HPLC-(Q-TRAP)-MS/MS] was used to quantitatively detect the candidate substance in the urine of rats. SPSS 20.0 was used to process and analyze the measurement data. Wilcoxon rank-sum test was used for comparison between groups. Python 3.0 was used to plot the receiver operator characteristic (ROC) curve. P < 0.05 was considered to be statistically significant. Results:Histological observation showed that in model group, the joint space narrowed or disappeared, the cartilage became thinner, damaged or extensively exfoliated. The chondrocytes were degenerated, necrotic or absence. With the extension of the experimental cycles, the lesions worsened. Targeted metabolomics study found that 7 different metabolites were screened at 4 weeks, namely fumaric acid, succinic acid, oxaloacetic acid, malic acid, cis-aconite acid, α-ketoglutaric acid and sulfoalanine. Sulfoalanine was low expressed in model group and other 6 organic acids were high expressed ( P < 0.05). At 8 weeks, a total of 12 different metabolites were screened, including histidine, lysine, tyrosine, tryptophan, threonine, valine, leucine, aspartic acid, creatinine, α-ketoglutaric acid, oxaloacetic acid and malonyl carnitine, all of them were highly expressed in model group ( P < 0.05). At 12 weeks, a total of 4 different metabolites were screened, among which sulfoalanine, cysteine and sarcosine were low expressed in model group, and succinic acid was high expressed ( P < 0.05). Conclusions:Typical OA pathology changes and disease progress in the rats of model group are exhibited, the model is established successfully. The urinary small molecular metabolite profiles of OA rats with different disease progress are different, mainly organic acids and amino acids. The metabolites related to urinary tricarboxylic acid cycle and essential amino acids can be used as biomarker clusters of OA.
