ABSTRACT

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020, the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS, and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time, a nested case-control study (the ratio of trial group and control group was 1∶4) was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients, 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection, with the incidence of 0.076%. There was no serious adverse event, and the occurrence time was 2 days after medication; adverse drug events mainly include elevated liver function indicators (alanine transaminase, aspartate transaminase, total bilirubin), which were mild and untreated, and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline, and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high, and the occurrence of adverse events is more related to it.

ABSTRACT

Objective: This article investigated the clinical characteristics and distribution of drug resistance mutation sites in HBV RT region of hepatitis B infected patients. Methods: Retrospective analysis was made on 1 948 patients with HBV infection, who had been tested for NAs resistance mutation and had a medical history of NAs in the Laboratory Department of the Fifth Medical Center of the PLA General Hospital from January 2020 to December 2021. Basic clinical information and drug resistance related mutation information were recorded. Meanwhile, the serological index data of hepatitis B were collected. Drug resistance gene mutant group and non-mutated group were grouped according to whether the drug resistance genes had a mutation in HBV RT region, and the clinical characteristics and genotype distribution of the two groups were statistically analyzed. The pattern of drug resistance gene mutation, number of mutation sites, drug resistance type and mutation of NAs resistance-related sites were analyzed in 917 patients with drug resistance gene mutation in HBV RT region. χ2 Inspection was used for counting data. Meanwhile, two independent samples t-test and Wilcoxon rank sum test were used for measurement data. Results: Among the 1 948 patients with chronic HBV infection, 917 patients had drug resistance gene mutation in RT region (47.07%). The proportion of patients with acute hepatitis B and CHB in HBV RT resistance gene mutant group was lower than that in the non-mutated group, while the proportion of patients with HBV-related cirrhosis was higher than that in the non-mutated group, these differences were statistically significant. Compared with the non-mutated group in HBV RT region, the age, the positive rates of HBeAg and HBV DNA, and HBV DNA load of these patients were increased in drug resistance gene mutant group, these differences were statistically significant. Genotypes of patients in both groups were dominated by C, followed by B and D. The proportion of patients with genotype C in HBV RT drug resistance gene mutant group was higher than that of non-mutated group, the difference was statistically significant. There were 53 gene mutation patterns in 917 patients with drug resistance gene mutation in HBV RT region, and the main pattern was rtL180M+rtM204V+rtS202G (9.70%). The mutation sites were dominated by 3 (20.74%). There were 5 types of drug resistance, LAM+Ldt (21.25%) was the most. Among the 18 sites that were clearly associated with LAM, ADV, ETV and Ldt resistance in the HBV RT region, 14 sites were mutated, and the most common mutation sites were rtL180M, rtM204V, rtM204 and rtS202G. what's more, the proportion of patients with NAs drug resistance was LAM>Ldt>ETV>ADV. Conclusion: In order to prevent adverse consequences of this study such as disease recurrence or disease progression caused by HBV drug resistance, HBV infected patients, who have long-term use of NAs antiviral therapy, should monitor the level of HBV DNA and drug resistance genes in HBV RT region in order to optimize the treatment plan in time or guide individualized treatment.

ABSTRACT

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is characterized by diffuse alveolar injury primarily caused by an excessive inflammatory response. Regrettably, the lack of effective pharmacotherapy currently available contributes to the high mortality rate in patients with this condition. Xuebijing (XBJ), a traditional Chinese medicine recognized for its potent anti-inflammatory properties, exhibits promise as a potential therapeutic agent for ALI/ARDS. This study aimed to explore the preventive effects of XBJ on ALI and its underlying mechanism. To this end, we established an LPS-induced ALI model and treated ALI mice with XBJ. Our results demonstrated that pre-treatment with XBJ significantly alleviated lung inflammation and increased the survival rate of ALI mice by 37.5%. Moreover, XBJ substantially suppressed the production of TNF-α, IL-6, and IL-1β in the lung tissue. Subsequently, we performed a network pharmacology analysis and identified identified 109 potential target genes of XBJ that were mainly involved in multiple signaling pathways related to programmed cell death and anti-inflammatory responses. Furthermore, we found that XBJ exerted its inhibitory effect on gasdermin-E-mediated pyroptosis of lung cells by suppressing TNF-α production. Therefore, this study not only establishes the preventive efficacy of XBJ in ALI but also reveals its role in protecting alveolar epithelial cells against gasdermin-E-mediated pyroptosis by reducing TNF-α release.

ABSTRACT

Objective@#This study aimed to identify internal ribosome entry sites (IRESs) in the open reading frame (ORF) of the Coxsackievirus B3 (CVB3) genome.@*Methods@#The sequences of P1, P2, or P3 of the CVB3 genome or the truncated sequences from each antithymocyte globulin (ATG) to the end of the P1, P2, or P3 gene were inserted into the pEGFP-N1 vector. After transfection, possible IRES-dependent green fluorescent protein (GFP)-fused proteins were detected by anti-GFP western blotting. The sequences of possible IRESs were inserted into specific Fluc/Rluc bicistronic vectors, in which the potential IRESs were determined according to the Fluc/Rluc activity ratio. Expression of Fluc and Rluc mRNA of the bicistronic vector was detected by RT-qPCR.@*Results@#After transfection of full length or truncated sequences of the P1, P2, or P3 plasmids, six GFP-fused protein bands in P1, six bands in P2 and nine bands in P3 were detected through western blotting. Two IRESs in VP2 (1461-1646 nt) and VP1 (2784-2983 nt) of P1; one IRES in 2C (4119-4564 nt) of P2; and two IRESs in 3C (5634-5834 nt) and 3D (6870-7087 nt) of P3 were identified according to Fluc/Rluc activity ratio. The cryptic promoter was also excluded by RT-qPCR.@*Conclusion@#Five IRESs are present in the CVB3 coding region.

ABSTRACT

Objective: To study the effects of exosome secreted by ovarian cancer (OC) cell on the differentiation and metastasis of normal fibroblasts (NFs). Methods: NFs were collected from patients who underwent hysteromyoma resection in the Affiliated Hospital of Qingdao University from May to December 2019. Exosome was extracted from the culture supernatant of SKOV3 cells by using ultra-high-speed centrifugation. The NFs were co-cultured with condition medium (CM), exosome of SKOV3 (SKOV3-exo) and control medium. The expression levels of fibroblast activation protein (FAP) and α-smooth muscle actin (α-SMA) were detected by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and western blot. The metastatic ability of NFs was detected by Transwell array. Results: Under the transmission electron microscope, the extracellular vesicles extracted from the culture supernatant of SKOV3 were 30-100 nm in diameter with cup holder-like bilayer membrane structure, and the protein expression levels of TSG101 and HSP27 in exosomes (1.00±0.05 and 1.12±0.13) were higher than those of ovarian cancer SKOV3 cells (0.22±0.21 and 0.36±0.14, respectively, P<0.05). PKH67 fluorescently labeled exosomes could be taken up by NFs. The expression levels of α-SMA and FAP mRNA in CM group(2.91±0.15 and 3.21±0.33)and SKOV3-exo group (3.50±0.21 and 4.63±0.24, respectively) were higher than that in blank group (1.00±0.06 and 1.00±0.13, P<0.05). The protein expression levels of α-SMA and FAP in CM group and SKOV3-exo group (0.89±0.11 and 1.25±0.09, 0.81±0.09 and 1.20±0.12) were higher than those in the blank group (0.12±0.31 and 0.11±0.19, respectively, P<0.05). The migrated numbers of cells in the CM group and SKOV3-exo group [(215.01±14.80) and (389.72±19.43), respectively] were higher than that in the blank group [(113.73±4.70), P<0.05]. Conclusion: The exosome secreted by SKOV3 cells can be taken up by NFs, which makes it to differentiate into cancer associated fibroblasts (CAFs) and significantly enhances its metastatic ability, indicating that OC cells may promote the transformation of normal ovarian mesenchymal fibroblasts to CAFs through exosome pathways, and then promote the development of ovarian cancer.

ABSTRACT

OBJECTIVES@#To establish a nomogram model for predicting the risk of death of very preterm infants during hospitalization.@*METHODS@#A retrospective analysis was performed on the medical data of 1 714 very preterm infants who were admitted to the Department of Neonatology, the Third Affiliated Hospital of Zhengzhou University, from January 2015 to December 2019. These infants were randomly divided into a training cohort (1 179 infants) and a validation cohort (535 infants) at a ratio of 7∶3. The logistic regression analysis was used to screen out independent predictive factors and establish a nomogram model, and the feasibility of the nomogram model was assessed by the validation set. The area under the receiver operating characteristic curve (AUC), calibration curve, and decision curve analysis (DCA) were used to assess the discriminatory ability, accuracy, and clinical applicability of the model.@*RESULTS@#Among the 1 714 very preterm infants, 260 died and 1 454 survived during hospitalization. By the multivariate logistic regression analysis of the training set, 8 variables including gestational age <28 weeks, birth weight <1 000 g, severe asphyxia, severe intraventricular hemorrhage (IVH), grade III-IV respiratory distress syndrome (RDS), and sepsis, cesarean section, and use of prenatal glucocorticoids were selected and a nomogram model for predicting the risk of death during hospitalization was established. In the training cohort, the nomogram model had an AUC of 0.790 (95%CI: 0.751-0.828) in predicting the death of very preterm infants during hospitalization, while in the validation cohort, it had an AUC of 0.808 (95%CI: 0.754-0.861). The Hosmer-Lemeshow goodness-of-fit test showed a good fit (P>0.05). DCA results showed a high net benefit of clinical intervention in very preterm infants when the threshold probability was 10%-60% for the training cohort and 10%-70% for the validation cohort.@*CONCLUSIONS@#A nomogram model for predicting the risk of death during hospitalization has been established and validated in very preterm infants, which can help clinicians predict the probability of death during hospitalization in these infants.

ABSTRACT

Objective:To document the clinical features of children with cerebral palsy (CP) using magnetic resonance imaging (MRI).Methods:The gross motor functioning of 325 children diagnosed as having CP was graded using the gross motor function classification system (GMFCS). The GMFCS grades were correlated with MRI results in univariate and multivariate logistic regression analyses. The significance of any relationship between the MRI results and co-morbidities was tested using chi-squared tests.Results:Cerebral dysplasia, cerebroventricular enlargement, periventricular leukomalacia (PVL), abnormal signals in the thalami, and morphological changes after hypoxic ischemic encephalopathy were all found to be significantly correlated with GMFCS grading. Moreover, the chi-squared tests indicated that PVL children, children with thinning of the corpus callosum and/or abnormal signals in the thalami were significantly more likely to have visual, auditory or speech impairment complications and/or mental retardation.Conclusions:The findings from MRI correlate well with types of CP, GMFCS grades and co-morbidities among CP children. MRI can be an effective tool for early diagnosis and prognosis of CP in children, indicating needs for clinical rehabilitation.

ABSTRACT

Objective:To analyze the epidemiological characteristics and genotypes of human rhinovirus (HRV) in patients with upper respiratory tract infection in Qingdao in the winter of 2020.Methods:Throat swab samples were collected from 101 patients with upper respiratory tract infection in Qingdao from November 2020 to January 2021. Quantitative PCR was used to detect 15 common respiratory viruses in the samples. HRV-positive samples were further analyzed with RT-PCR to amplify and sequence HRV VP4/VP2 gene. A phylogenetic tree was constructed based on the sequencing results and homology analysis was conducted.Results:Six common respiratory viruses were detected in the 101 patients. Thirty-four cases (34/101, 33.66%) were single pathogen infection and two cases were multiple infection (2/101, 1.98%). The positive rate of HRV was the highest (21.78%, 22/101). Twenty HRV VP4/VP2 sequences were successfully amplified. Phylogenetic analysis showed that there were 16 strains of HRV-A subtype and four strains of HRV-C subtype and 14 serotypes were involved.Conclusions:HRV was one of the leading viral pathogens causing upper respiratory tract infection in Qingdao in the winter of 2020 and the predominant subtype was HRV-A.

ABSTRACT

BACKGROUND@#Core muscle functional strength training (CMFST) has been reported to reduce injuries to the lower extremity. However, no study has confirmed whether CMFST can reduce the risk of low back pain (LBP).@*OBJECTIVE@#This study identified the effects of CMFST on the incidence of LBP in military recruits.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#We performed a prospective, open-label, randomized, controlled study in a population of young healthy male naval recruits from a Chinese basic combat training program. Participants were randomly assigned to either the core group or the control group. In additional to normal basic combat training, recruits in the core group underwent a CMFST program for 12 weeks, while recruits in the control group received no extra training.@*MAIN OUTCOME MEASURES@#At the beginning of the study and at the 12th week, the number of participants with LBP was counted, and lumbar muscle endurance was measured. In addition, when participants complained of LBP, they were assessed using the visual analog scale (VAS) and Roland Morris Disability Questionnaire (RMDQ).@*RESULTS@#A total of 588 participants were included in the final analysis (295 in the core group and 293 in the control group). The incidence of LBP in the control group was about twice that of the core group over the 12-week study (20.8% vs 10.8%, odds ratio: 2.161-2.159, P < 0.001). The core group had better lumbar muscle endurance at 12 weeks than the control group ([200.80 ± 92.98] s vs [147.00 ± 84.51] s, P < 0.01). There was no significant difference in VAS score between groups, but the core group had a significantly lower RMDQ score at week 12 than the control group (3.33 ± 0.58 vs 5.47 ± 4.41, P < 0.05).@*CONCLUSION@#This study demonstrated that the CMFST effectively reduced the incidence of LBP, improved lumbar muscle endurance, and relieved the dysfunction of LBP during basic military training.

ABSTRACT

OBJECTIVES@#To investigate the current status of sleep initiation patterns, influencing factors for sleep initiation patterns, and the influence of sleep initiation patterns on sleep quality in infants and young children.@*METHODS@#A total of 521 infants and young children, aged 0-35 months, who underwent physical examination at the outpatient service of the Department of Growth and Development in Shenzhen Bao'an Women's and Children's Hospital Affiliated to Jinan University were enrolled as subjects. A self-designed questionnaire and Brief Infant Sleep Questionnaire were used to collect the information on family background, parenting behaviors, and sleep quality in the past one week. A multivariate logistic regression analysis was used to evaluate the influencing factors for sleep initiation patterns. A multiple linear regression analysis was used to evaluate the influence of sleep initiation patterns on the number of nighttime awakenings.@*RESULTS@#Among the 521 infants and young children, 258 (49.5%) were breastfed/bottle fed to initiate sleep, 62 (11.9%) were rocked/held to initiate sleep, 39 (7.5%) slept independently, and 162 (31.1%) initiated sleep accompanied by parents. The multivariate logistic regression analysis showed that the children with breastfeeding and a younger age were more likely to be breastfed/bottle fed to initiate sleep (P<0.05) and that the children with a younger age were also more likely to be rocked/held to initiate sleep (P<0.05). The multiple linear regression analysis showed that sleep initiation with breastfeeding/bottle feeding significantly increased the number of nighttime awakenings (P<0.05).@*CONCLUSIONS@#Most infants and young children initiate sleep by being breastfed/bottle fed, rocked/held, or accompanied. The sleep initiation pattern is associated with the age of children and whether they are still breastfeeding. Sleep initiation with breastfeeding/bottle feeding can increase the number of nighttime awakenings. io.

ABSTRACT

The paper aims to establish the method to determine the monosaccharide composition and monosaccharide ratio in propylene glycol alginate sodium sulphate (PSS). Samples were hydrolyzed with trifluoroacetic acid, neutralized with sodium hydroxide solution after the reaction conditions for sample pretreatment were optimized via orthogonal analysis. A high performance anion exchange chromatograghy (HPAEC) coupled with pulsed amperometric detector (PAD) was performed on a CarboPac®PA20, using 200 mmol·L-1 sodium hydroxide solution and 1 mol·L-1 sodium acetate solution as mobile phase. The established HPAEC-PAD method was validated by testing the linear relationship, precision and accuracy, and showed exclusive, sensitive, rapid and wide use. The monosaccharide composition of PSS from different manufacture can be accurately determined with great significance for the structural identification of PSS.

ABSTRACT

Spontaneous cerebellar hemorrhage accounts for about 10% of all cases of cerebral hemorrhage and 15% of all cases of cerebellar stroke. The mortality is about 30%-50% in 30 d after onset. Patients with cerebellar hemorrhage can rapidly deteriorate due to enlarged hematoma and/or brain stem compression, leading to coma and death. Therefore, hematoma evacuation is the preferred treatment for spontaneous cerebellar hemorrhage, especially in patients with hematoma diameter >3 cm and accompanied by brainstem compression or hydrocephalus.

ABSTRACT

OBJECTIVE: To investigate the effect of electroacupuncture (EA) on silent information regulator 1 (SIRT1), forkhead transcription factor O1 (FoxO1), and proopiomelanocortin (POMC) in the hypothalamus of rats with high-fat diet-induced obesity (DIO), as well as the mechanism of EA in regulating central appetite peptides to help lose weight. METHODS: Male Wistar rats were randomly divided into normal group, model group, EA group, EA+inhibitor group, inhibitor group, and sham-operation group, with 10 rats in each group. High-fat diet was used to establish a rat model of DIO. The rats in the EA group and EA+inhibitor group were given EA at "Fenglong" (ST40), "Zhongwan "(CV12),"Guanyuan "(CV4), and"Zusanli" (ST36) with continuous wave at a frequency of 2 Hz and an intensity of 1 mA, for 10 minutes each time. The rats in the EA+inhibitor group and inhibitor group were given tube placement in the third ventricle and injection of the specific SIRT1 antagonist EX-527. The rats in the sham-operation group were given tube placement in the third ventricle and injection of artificial cerebrospinal fluid. The above treatment was given 3 times a week for 8 weeks in total. Body weight, food intake, and Lee's index were observed before and after treatment. An automatic biochemical analyzer was used to measure the serum levels of total cholesterol (TC), triglyceride (TG), and free fatty acid (FFA), and Western blot was used to measure the protein expression of SIRT1, FoxO1, acetylated FoxO1(AC-FoxO1), and POMC in the hypothalamus. RESULTS: Before treatment, the model group, the EA group, the EA+inhibitor group, the inhibitor group, and the sham-operation group had significantly higher body weight and food intake than the normal group (P<0.01), and the model group and the sham-operation group had a significantly higher Lee's index than the normal group (P<0.05). Compared with the model group after treatment, the EA group and the EA+inhibitor group had significant reductions in body weight, food intake, TC, and the protein expression of AC-FoxO1 (P<0.01, P<0.05) and significant increases in the protein expression of SIRT1, FoxO1 and POMC (P<0.01, P<0.05); the EA group had significant reductions in Lee's index and the levels of TG, FFA(P<0.05,P<0.01);the inhibitor group had significant increases in food intake, the serum levels of TC, TG, FFA(P<0.01) and significant reductions in the protein expression of SIRT1, FoxO1 and POMC (P<0.01,P<0.05). Compared with the EA group, the EA+inhibitor group and the inhibitor group had significant increases in body weight, food intake, Lee's index, the levels of TG, FFA and the protein expression of AC-FoxO1 (P<0.01, P<0.05) and significant reductions in the protein expression of SIRT1, FoxO1 and POMC (P<0.01); the inhibitor group had significant increases in the serum levels of TC (P<0.01). Compared with the EA+inhibitor group, the inhibitor group had significant increases in body weight, food intake, the serum levels of TC, TG, FFA, and the protein expression of AC-FoxO1 (P<0.01), as well as significant reductions in the protein expression of SIRT1, FoxO1 and POMC (P<0.01). CONCLUSION: In rats with DIO, EA can effectively up-regulate the expression of SIRT1 in the hypothalamus, exert a deacetylation effect on FoxO1, and promote the expression of the downstream appetite-inhibiting peptide POMC, which may be one of the mechanisms of EA to help lose weight by regulating central appetite peptides in the obesity model.

ABSTRACT

Objective@#To investigate the incidence of human rhinovirus (HRV) infection in hospitalized patients in emergency department.@*Methods@#A total of 94 emergency patients admitted to the emergency department from November to December of 2018 were enrolled in this study. The rhinovirus infection and related risk factors were analyzed.@*Results@#HRV infection occurred in 17 out of 94 hospitalized patients in emergency department, the infection rate was 18.09%; Multiple HRV serotypes were prevalent from November to December of 2018, which were A9, A10, A16, A31, A73, B42 and C3. Elderly patients are at high risk of rhinovirus infection; Rhinovirus infection may increase the course of inpatients.@*Conclusions@#From November to December of 2018, multiple serotypes of HRV infections in the emergency department of Bengbu, Anhui, and HRV easily infected elderly inpatients.

ABSTRACT

Objective@#To isolate and identify human rhinovirus (HRV) from throat swab samples from patients with acute respiratory infection in Anhui Bengbu.@*Methods@#The throat swab specimens from 108 patients with acute upper respiratory tract infection diagnosed in the Anhui Bengbu were selected as samples. RNA was extracted and detected by HRV universal primers; H1-Hela cells were infected with the positive samples for virus isolation, and HRV VP1 gene amplification was performed and gene phylogenetic tree analysis of the successfully isolated HRV strains was done.@*Results@#Only 5 samples were positive for HRV by the real-time PCR, and only one sample showed significant cytopathic effects after three passages of H1-Hela cells were infected, and the HRV VP1 gene was amplified by RT-PCR in the sample that was named TYZQ201901. The sequence analysis showed that the VP1 nucleotide homology of the strain with other representative HRV A strains was over 95%. The gene phylogenetic tree analysis showed that the strain had the closest genetic distance to the RMH127/2013 strain, and both were on a branch and was confirmed to be HRV type A virus.@*Conclusions@#An HRV type A strain virus was isolated from throat swab samples from patients with acute respiratory infection in Anhui Province by the H1-Hela cells, and the HRV virus separation technology system were initially established.
