ABSTRACT

Objective To evaluate the performance of myPKFiT,a tool guiding the dosing of antihemophilic factor (recombinant) plasma/albumin-free method (rAHF-PFM),in maintaining the coagulation factor Ⅷ (FⅧ) level above a target threshold at the steady state and estimating the pharmacokinetics (PK) parameters in hemophilia A patients in China. Methods The data of 9 patients with severe hemophilia A in a trial (CTR20140434) assessing the safety and efficacy of rAHF-PFM in the Chinese patients with hemophilia A were analyzed.The myPKFiT was used to predict the adequate dose to maintain a patient's FⅧ level above target threshold at the steady state.Furthermore,the performance of myPKFiT in estimating the pharmacokinetics parameters of individuals was evaluated. Results Twelve combinations of two dosing intervals and six sparse sampling schedules were investigated,and 57%-88% of the patients remained the FⅧ level above the target threshold of 1 U/dl (1%) for at least 80% of the dosing interval.The clearance and time to FⅧ level of 1% obtained from sparse sampling by myPKFiT were similar to those obtained from extensive sampling. Conclusions The myPKFiT can provide adequate dose estimates to maintain the FⅧ level above the target threshold at the steady state in Chinese patients with severe hemophilia A.Moreover,it demonstrates good performance for estimating key pharmacokinetics parameters,including clearance and time to FⅧ level of 1%.

ABSTRACT

Objective:To compare the effects of low-carbohydrate diet (LCD) and low-fat diet (LFD) in the lifestyle intervention of non-alcoholic fatty liver disease (NAFLD) through a meta-analysis of randomized controlled trials.Methods:PubMed, Embase, Web of Science, Cochrane, CNKI and Wanfang were searched for relevant studies and study references and conference proceedings were manually searched. Two authors independently screened the items retrieved, extracted the data and assessed the quality of included studies. Meta-analysis was performed using R4.4.1 and RevMan5.4.1. Data were pooled using random-effects models and potential sources of heterogeneity were investigated using stratified meta-analysis. Funnel plots and Peters' test were used to assess publication bias.Results:Nine studies with a total of 510 participants met our inclusion criteria. Meta-analysis results showed that LCD and LFD interventions had similar effects on the reduction of intrahepatic lipid content in NAFLD patients ( SMD: -0.31,95% CI: 0.97 to 0.35, P = 0.36). There were no significant differences in changes of alanine aminotransferase ( SMD: -0.25, 95%CI: 0.91 to 0.41, P = 0.45) and aspartate aminotransferase ( SMD: -0.45, 95%CI: 1.63 to 0.72, P = 0.45) levels, either. Subgroup analyses implied that the duration of different interventions might be the cause of heterogeneity across studies. No significant publication bias was showed in the meta-analysis. Conclusion:Current evidence from randomized controlled studies does not support the superiority of LCD over LFD in the treatment of NAFLD.

ABSTRACT

Objective:To explore the potential mechanism of Bianketong tablet (BKT) in the treatment of constipation-predominant irritable bowel syndrome (C-IBS) based on network pharmacology and bioinformatics. Method:The BKT-meridian network was constructed for analyzing the combined effect of the nine Chinese herbs in BKT. The active components and targets of BKT were collected from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and then screened according to the oral bioavailability (OB) and drug likeness (DL) criteria. Following the acquisition of C-IBS target set from GeneCards, Online Mendelian Inheritance in Man (OMIM), Drugbank and DisGeNet, the protein-protein interaction (PPI) network was constructed. Cytoscape 3.7.2 was utilized for network visualization. The screened key targets were subjected to gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis using DAVID platform. The C-IBS mouse model was established via intragastric administration of ice water, and the key targets of BKT against C-IBS were verified by enzyme linked immunosorbent assay (ELISA) and immunohistochemistry. Result:The large intestinal meridian was the main site where BKT acted. There were 70 potential active components in BKT, which acted on 227 intersection targets. Through T helper cell 17(Th17) differentiation, Toll-like receptor (TLR), tumor necrosis factor and other signaling pathways, BKT participated in inflammatory response, immune regulation, intestinal nerve regulation, hormonal regulation, and oxidative stress response, thus exerting the therapeutic effects against C-IBS. As reveled by <italic>in vivo</italic> experiments, BKT significantly improved the small intestinal propulsion rate, up-regulated the expression of vasoactive intestinal peptide (VIP) in serum and colon tissue of C-IBS mice, and down-regulated the expression of nuclear transcription factor-<italic>κ</italic>B (NF-<italic>κ</italic>B), interleukin(IL)-6, and TLR2 in serum and colon tissue, which confirmed the reliability of integration analysis. Conclusion:BKT inhibits C-IBS via multiple components, multiple targets, and multiple pathways. This study has provided ideas for further clinical research and experimental verification of BKT in the treatment of C-IBS.

ABSTRACT

Objective:To explore the relationship between level of urinary iodine excretion (UIE) before 131I treatment and excellent response (ER) in low-to-intermediate risk differentiated thyroid carcinoma (DTC) patients. Methods:A retrospective analysis was performed with 432 DTC patients (124 males, 308 females, age: (42.1±11.0) years) who were treated with 131I for the first time after total thyroidectomy from June 2017 to October 2018 in Department of Nuclear Medicine, the Second Hospital of Shandong University. All patients were divided into 4 groups: G1, group 1, UIE<50 μg/L; G2, group 2, 50 μg/L≤UIE<100 μg/L; G3, group 3, 100 μg/L≤UIE<200 μg/L; G4, group 4, UIE≥200 μg/L. Patients were given 131I with a fixed dose (3 700 MBq). Response was evaluated 6 to 8 months after 131I treatment: ER, indeterminate response (IDR), biochemical incomplete response (BIR), and structural incomplete response (SIR). χ2 test and Kruskal-Wallis rank sum test were used to analyze the data. The adjusted standardized residual (residual) and Cramer′s V between G1-G4 and different treatment reactions were calculated to judge the difference among groups. IDR, BIR and SIR were classified into non-ER (NER) group, and binary logistic regression analysis and receiver operating characteristic (ROC) curve analysis were performed to find the influencing factors of treatment reactions. Results:There were 51.9%(41/79), 64.9%(98/151), 53.8%(63/117), 30.6%(26/85) patients achieved ER in G1-G4, and the proportion of G4 was significantly lower than that of G1-G3 ( χ2 values: 7.695-25.697, all P<0.05), and there was no significant difference among G1-G3 ( χ2 values: 0.072-3.667, all P>0.05). The UIE level of patients in ER, IDR, BIR, SIR group was 87.5(57.0, 129.0), 97.0(55.7, 211.5), 141.0(74.0, 231.0), 148.0(68.5, 221.0) μg/L( H=15.977, P=0.001), and there was significant difference between those of patients in ER and SIR groups ( χ2=8.729, P=0.019). There was a certain correlation between UIE levels and different treatment reactions (Cramer′s V=0.151, P=0.001). UIE (≥200 μg/L), gender and preablative stimulated thyroglobulin could be used as independent factors affecting ER ( Wald values: 4.029, 7.185, 56.301, all P<0.05). Conclusion:Among DTC patients with low-to-intermediate risk, 131I treatment does not affect ER when the UIE level is less than 200 μg/L, while 131I treatment should be performed carefully when the UIE level is more than 200 μg/L.

ABSTRACT

Objective:To conduct the integrated management of hospital, community and family for patients with insulin injection at home, in order to explore the influence of this trinity health education model on the knowledge of medical waste and the standard disposal of discarded needles.Methods:The self-designed questionnaire was used to investigate the knowledge and disposal of medical waste in outpatients, and the causes were analyzed carefully after the problems were found. The hospital, community and family were timely communicated and fed back to the ward and community. After 1, 3 and 6 months of educational intervention, the disposal of insulin needles, the knowledge of medical waste and the recovery of sharp instrument boxes were observed.Results:After 1, 3 and 6 months of health education, the final rate of insulin needles mixed into domestic waste was 51.8% (144/278), 15.1% (42/278) and 4.7% (13/278), respectively. Compared with the first result of 99.6% (277/278), the difference was statistically significant ( χ2=173.046, 406.136, 502.346, P<0.01); The first survey found that the correct rate of responding to medical waste knowledge items was low. After health education for 1, 3 and 6 months, the correct rate of medical waste related knowledge items was significantly higher than that of the first survey, and the difference was statistically significant ( OR=3.016-3 548.810; 95% CI 2.108-917.869, 4.315-19 777.062; χ2=25.180-524.895; P<0.01) ; After 1, 3 and 6 months of health education, the qualified rate of medical waste knowledge was 82.4% (229/278),75.9% (211/278) and 97.1% (270/278), respectively, which was significantly higher than the first result of 6.5% (18/278). The difference was statistically significant ( χ2=324.328, 273.712, 453.832, P<0.01). The sharp box recovery of hepatitis B patients was relatively good. Conclusion:Hospital-community-family Trinity health education model can improve the breadth and depth of education objects, not only can improve the knowledge of medical waste related to insulin injection patients at home, but also can improve the standardized disposal ability of insulin waste needles. With the passage of time, the effect of health education continues to be good. This integrated health education model is worth popularizing in clinic.

ABSTRACT

Overlap extension PCR is a common method for site-directed mutagenesis. As objective gene sequence growing longer, it is often difficult to obtain the target product in the second round of PCR, and it is highly possible to introduce unexpected mutations into a long gene fragment by PCR. To circumvent these problems, we can only amplify a small gene fragment which contain the target mutation by overlap extension PCR, and then ligate it with vector to get target plasmid. If the restriction site at the end of the amplified fragment was not a single one on plasmid vector, double fragments ligation method could be used to construct target plasmid. Partial amplification, combined with double fragments ligation, could solve lots of problems in long gene mutagenesis. Taking retinoblastoma gene 1 S780E mutagenesis as an example, it is difficult to amplify whole retinoblastoma gene 1 by overlap extension PCR because of long fragment interfering the overlapping extension of second round PCR. However, it is relatively easy to amplify the F3 (1 968-2 787) fragment which contains target mutation S780E. There is a Nhe I site which can be used for ligation on 5' end of F3 fragment, but another Nhe I site on the plasmid restrained from doing so directly. In order to circumvent this obstacle, we ligated F3 fragment, combining with F2 (900-1 968) fragment which was digested from wild type plasmid, with the vector which contain F1 (1-900) fragment of the gene. That double fragments ligated with one vector at the same time, though less efficient, can recombine into a complete plasmid. The sequences of the two selected recombinant plasmids were consistent with the target mutation, which verified the feasibility of this scheme. As an improvement of overlap extension PCR, partial amplification and double fragments ligation methods could provide solutions for site directed mutagenesis of many long genes.

ABSTRACT

OBJECTIVE@#To evaluate the clinical effects of debridement and bone grafting with internal fixation via anterior approach in treatment of tuberculosis of lower cervical vertebrae.@*METHODS@#The clinical data of 15 patients with tuberculosis of lower cervical vertebrae who accepted the treatment of one-stage debridement and bone grafting with internal fixation from June 2010 to December 2018 were retrospectively analyzed. There were 9 males and 6 females, aged from 39 to 72 years with an average of (54.67±10.75) years. The lesion segment was C to C. Pre- and post-operative neurologic functions were evaluated by ASIA grade. All the patients underwent the X-ray films of positive and lateral of cervical spine before and after the operation and accepted the periodic review of CT to evaluate the bone grafting.@*RESULTS@#All the 15 operations were successful, no neurological or vascular injury occurred during the operation, and all patients were followed up for 18 to 52 months. The clinical symptoms improved significantly during the follow-up period and CT showed good bone grafting fusion. One patient suffered a relapse of the illness 3 years later, but was healed during the follow-up visit by strengthening the anti tuberculosis therapy.@*CONCLUSION@#For the patients with vertebral destruction and loss of cervical stability, one-stage debridement and bone grafting with internal fixation via anterior approach has definite curative effects. On the basis of standard anti tuberculosis treatment before operation, the long-term standard anti-tuberculosis treatment after operation is the key to healing the tuberculosis of lower cervical vertebrae.

ABSTRACT

Annexin A3(ANXA3), is a crucial member of the membrane associated protein superfamily, whose function research is still insufficient. Previous researches have confirmed that Annexin A3 is involved in a variety of cellular processes, but its function is still unclear. Accumulating evidences suggested that Annexin A3 is closely related to various malignant tumors, and plays an important role in tumor development, metastasis, invasion and drug resistance. Therefore, Annexin A3 is expected to be a new therapeutic target for malignant tumors. This article provided an overview about the role of Annexin A3 in malignant tumors.

ABSTRACT

Objective To investigate the association between depression behavior and the expression of calreticulin precursor, tropomyosin I, milogen activated prolein kinase 1 and dual specificity mitogen-activated protein kinase 1 in spontaneous diabetes mellitus rats. Methods Twenty adult male healthy rats (control group) and 40 spontaneous diabetic rats were studied. Forty spontaneous diabetic rats were further divided into diabetes group and diabetic depression group, and the latter was to construct depression model. The depressive behavior of the 3 groups was measured by sucrose water consumption test and wilderness test. The expression level of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogen-activated protein kinase 1 in the hippocampus of the 3 groups was measured by western blot. Results In the 15 th day and 22 nd days of stress, the amount of sucrose water drinking of the rats in diabetic depression group was significantly lower than that of the control group and the diabetes group (P < 0.05) , and there was no significant difference between the control group and the diabetic group (P> 0.05). The score of field test and vertical score in the diabetic depression group were significantly lower than those of the control group and the diabetes group (P < 0.05) , but there was no significant difference between the control group and the diabetic group (P> 0.05). The expression of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogen-activated protein kinase 1 in the hippocampus of diabetic depression group was significantly lower than that in the control group and the diabetic group (P < 0.05) , and there was no significant difference between the control group and the diabetic group (P> 0.05).Conclusions The depressive behavior of spontaneously diabetic rats is associated with the decrease of the expression level of calreticulin precursor, tropomyosin 1, milogen activated prolein kinase 1, and dual specificity mitogenactivated protein kinase 1 in the hippocampus of rats.

ABSTRACT

OBJECTIVE@#To investigate whether kirenol, the major pharmacologically active compound of the Chinese medicinal herb , can protect mice from dextran sulfate sodium (DSS)-induced ulcerative colitis (UC).@*METHODS@#C57BL/6 mice with or without kirenol pretreatment were treated with DSS in drinking water for 7 days to induce UC. The symptoms of UC including weight loss, diarrhea and bloody stool were observed daily and graded using the disease activity index (DAI). Colon injury of the mice was assessed by measuring the length of the colon and HE staining of the colon tissue. The levels of inflammatory cytokines produced by the mesenteric lymph nodes (MLNs) lymphocytes were measured using enzyme-linked immunosorbent assay; the apoptosis of the lymphocytes and CD4 T cells was analyzed using flow cytometry.@*RESULTS@#The mice receiving pretreatment with kirenol showed obviously ameliorated symptoms of UC and milder pathological changes in the colon as compared with the control mice. Kirenol treatment significantly down-regulated the secretion of IFN-γ, IL-17A, IL-6 and TNF-α by the MLNs lymphocytes and increased the apoptosis of lymphocytes, especially CD4 T cells in the DSS-treated mice.@*CONCLUSIONS@#Kirenol can protect against T cell-mediated colon injury in DSS-treated mice possibly by suppressing the secretion of inflammatory mediators and inducing apoptosis of the inflammatory lymphocytes.

Hemophilia A is a hereditary hemorrhagic disease.Vaccination can prevent certain diseases,while intramuscular vaccination may lead to muscle hematoma in children with hemophilia A,even become a high risk factor for increasing production of inhibitors.Therefor,there are concerns about vaccination of hemophilia A.Children with hemophilia A can be vaccinated in a relatively safe manner,such as subcutaneous injections,or vaccinated after replacement treatment.There is no clear correlation between the immune response induced by vaccination and the mechanism of inhibitor production,and the safety of vaccination remains to be further studied.This review focuses on the progress of vaccination for children with hemophilia A.

ABSTRACT

Objective To describe the prevalence of preterm birth (PB),low birth weight (LBW),and small for gestational age (SGA) among HIV-infected pregnant women and to identify associated risk factors in Hunan province.Methods This study appeared a retrospective one on HIV-infected pregnant women retrieved from Information System of Prevention of Mother-to-child Transmission of HIV management in Hunan province,between January 2011 and December 2017.Information regarding demographic characteristics,pregnancy,antiretroviral therapy (ART),husbands/partners' relevant situation and pregnancy outcomes,among these HIV-infected pregnant women were collected and analyzed.The incidence rates on PB,LBW and SGA were calculated.Multivariate logistic regression was used to analyze the associated risk factors.Results A total of 780 HIV-infected pregnant women were enrolled.The prevalence rates on PB,LBW and SGA in HIV-infected pregnant women appeared as 7.9% (62/780),9.9% (77/780) and 21.3% (166/780),respectively.Results from the multivariate logistic regression analysis showed that factors as pregnancy related diseases as moderate/severe anemia,hypertensive,initial time of ART <14 gestational weeks (compared to those women without ART during pregnancy) and husbands/partners' age >35 years old (compared to husbands/partners' age 26-30 years old) etc.,were associated with an increased risk of PB with adjusted OR as 4.59 (95%CI:1.51-13.95),4.90 (95%CI:1.56-15.46),2.40 (95%CI:1.26-4.56) and 2.29 (95%CI:1.21-4.36).For LBW,pregnancy moderate/severe anemia,pregnancy HBV infection and initial time of ART < 14 gestational weeks were associated with an increased risk of LBW,with adjusted OR as 3.28 (95%CI:1.13-9.54),4.37 (95%CI:1.42-13.44) and 2.68 (95%CI:1.51-4.76),respectively.For SGA,pregnancy HBV infection and initial time of ART < 14 gestational weeks were risk factors for SGA,with adjusted OR as 4.41 (95%CI:1.43-13.63) and 2.67 (95%CI:1.51-4.73),respectively.Conclusion Preterm birth,LBW and SGA were common adverse pregnancy outcomes for HIV-infected pregnant women and were associated with factors as pregnancy complications,ART and husbands/partners' age.

ABSTRACT

This prospective study was conducted to compare risk factors and pregnancy outcomes between women with complete placenta previa and those with incomplete placenta previa diagnosed in mid-pregnancy.The study was carried out from April 2014 to December 2015,during which 70 patients with complete previa and 113 with incomplete previa between 20+0 weeks and 25+6 weeks of gestation were included.Maternal demographics and pregnancy outcomes were compared between the two groups.Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test.Resolution ofprevia occurred in 87.43% of the studied women.The mean gestational age at resolution was 32.1±4.4 weeks.Incidence of maternal age ≥35 years and incidence of prior uterine operation >3 were high in women with complete previa (28.6%vs.8.8%,P=0.003;28.6% vs.8.8%,P=0.003).Resolution of previa occurred less often in complete previa group (74.3% vs.95.6%,P=0.001).Women with complete previa admitted earlier (37.3±2.0 weeks vs.38.1±1.4 weeks,P=0.011) and delivered earlier (37.7±1.2weeks vs.38.3±1.4 weeks,P=0.025).Maternal age ≥35 years and prior uterine operation >3 increase the risk of complete previa in mid-pregnancy.Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in midpregnancy.What is more,women with complete previa in mid-pregnancy deliversearlier.
