ABSTRACT

AIM: To investigate the pharmacokinetic properties of the main active components of Dalitong extract in SD rats after oral administration using UPLC-MS / MS. METHODS: An UPLC-MS / MS method was established to simultaneously detect tetrahydropalmatine, nobiletin and costunolide in the plasma and tissues of SD rats. The method was applied to investigate the pharmacokinetic characteristics and tissue distribution. RESULTS: After a single oral administration, the three active components were rapidly absorbed into the body, with a peak concentration (Cmax) of (13.73 ± 7.50), (27.01 ± 17.69) and (6.73 ± 29.94) ng / mL for tetrahydropalmatine, nobiletin, and costunolide, respectively. The time to reach the peak concentration (Tmax) was (1.40 ± 0.93), (0.63 ± 0.28) and (2.38 ± 8.81) h, respectively. The area under the curve (AUC) was (80.43±40.03), (41.30±28.69) and (303.90 ± 136.69) ng · h · mL

ABSTRACT

BACKGROUND@#Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate.@*OBJECTIVE@#To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis.@*METHODS@#Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests.@*RESULTS@#A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence.@*CONCLUSION@#Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

ABSTRACT

ObjectiveTo explore the clinical effect of core muscle motor control training on postpartum diastasis recti abdominis. MethodsFrom January, 2021 to January, 2022, 30 outpatients with postpartum diastasis recti abdominis were randomly divided into control group (n = 15) and experimental group (n = 15). Manipulative therapy and breathing training were performed simultaneously in both groups. Besides, the control group received conventional core strength training, and the experimental group received core muscle motor control training, for four weeks. Their distance of diastasis recti abdominis, abdominal circumference and waist circumference were compared before and after treatment. ResultsAfter treatment, the distance of diastasis recti abdominis, abdominal circumference and waist circumference reduced in both groups (Z = 3.408, t > 5.927, P < 0.05). The reduction value of diastasis recti abdominis distance was more in the experimental group than in the control group (t = 2.328, P < 0.05). ConclusionCore muscle motor control training can effectively relieve postpartum diastasis recti abdominis, and the effect is better than conventional core strength training.

ABSTRACT

Objective:To evaluate the diagnostic value of 1, 3-β-D glucan (BDG), mannan IgM antibody (Mn-IgM) and mannan IgG antibody (Mn-IgG) in invasive candidiasis and to compare the differences in the diagnostic capability of serological markers used alone or in combination.Methods:Serum samples of 126 patients with invasive candidiasis and 104 healthy people who took physical examination during the same period were collected. BDG was detected by dynamic chromogenic method, and Mn-IgM and Mn-IgG were detected by ELISA. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index, coincidence rate and Kappa value of the three serological markers used alone or in combination in the diagnosis of invasive candidiasis were analyzed and compared. The receiver operating characteristic (ROC) curves were drawn and the areas under the curves (AUCs) were calculated.Results:The levels of BDG, Mn-IgM and Mn-IgG in patients with invasive candidiasis were significantly higher than those in healthy people ( P<0.01). The sensitivity, specificity, Kappa value and AUC of BDG were 48.41%, 92.31%, 0.389 and 0.842. The sensitivity, specificity, Kappa value and AUC of Mn-IgM were 64.29%, 91.35%, 0.540 and 0.829. The sensitivity, specificity, Kappa value and AUC of Mn-IgG were 27.78%, 95.19%, 0.214 and 0.737. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM were 76.19%, 88.46%, 0.637 and 0.921. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgG were 59.52%, 91.35%, 0.491 and 0.856. The sensitivity, specificity, Kappa value and AUC of Mn-IgM+ Mn-IgG were 69.84%, 90.38%, 0.588 and 0.891. The sensitivity, specificity, Kappa value and AUC of BDG+ Mn-IgM+ Mn-IgG were 80.16%, 88.46%, 0.679 and 0.922. Conclusions:The sensitivity of Mn-IgM was higher than that of BDG and Mn-IgG in the diagnosis of invasive candidiasis. When the serological biomarkers were used in combination, BDG+ Mn-IgM and BDG+ Mn-IgM+ Mn-IgG had relatively high Kappa value and AUC, showing high accuracy. The clinical diagnostic value of multiple serological biomarkers used in combination was significantly higher than that of any serological biomarkers used alone. Early combined detection and continuous monitoring of multiple serological biomarkers in patients with high risk of invasive candidiasis could be used clinically to adjust antifungal treatment strategies timely.

ABSTRACT

Autism spectrum disorder (ASD) is a highly heritable neurodevelopmental disorder characterized by deficits in social interactions and repetitive behaviors. Although hundreds of ASD risk genes, implicated in synaptic formation and transcriptional regulation, have been identified through human genetic studies, the East Asian ASD cohorts are still under-represented in genome-wide genetic studies. Here, we applied whole-exome sequencing to 369 ASD trios including probands and unaffected parents of Chinese origin. Using a joint-calling analytical pipeline based on GATK toolkits, we identified numerous de novo mutations including 55 high-impact variants and 165 moderate-impact variants, as well as de novo copy number variations containing known ASD-related genes. Importantly, combined with single-cell sequencing data from the developing human brain, we found that the expression of genes with de novo mutations was specifically enriched in the pre-, post-central gyrus (PRC, PC) and banks of the superior temporal (BST) regions in the human brain. By further analyzing the brain imaging data with ASD and healthy controls, we found that the gray volume of the right BST in ASD patients was significantly decreased compared to healthy controls, suggesting the potential structural deficits associated with ASD. Finally, we found a decrease in the seed-based functional connectivity between BST/PC/PRC and sensory areas, the insula, as well as the frontal lobes in ASD patients. This work indicated that combinatorial analysis with genome-wide screening, single-cell sequencing, and brain imaging data reveal the brain regions contributing to the etiology of ASD.

ABSTRACT

This study systematically reviewed the clinical efficacy of acupuncture for lumbar myofascial pain syndrome. The randomized controlled trials (RCTs) regarding acupuncture for lumbar myofascial pain syndrome were searched in PubMed, Cochrane Library, Web of Science, EMbase, Scopus, China national knowledge infrastructure (CNKI), Wanfang database, VIP database, and China biomedical literature service system (SinoMed) from database inception until August 1st, 2022. The Cochrane's risk of bias assessment tool was used to assess the risk of bias in all included studies, and Review Manager 5.3 software was used for statistical analysis of the extracted data. As a result, 12 RCTs, involving 1 087 patients with lumbar myofascial pain syndrome, were ultimately included. The Meta-analysis results showed that the visual analog scale (VAS) score of pain in the observation group was lower than those in the oral non-steroidal anti-inflammatory medication control [SMD=-1.67, 95%CI (-2.44, -0.90), Z=4.26, P<0.000 1] and other treatment control [low-frequency electrical stimulation, tuina, electromagnetic wave irradiation combined with piroxicam gel, SMD=-1.98, 95%CI (-2.48, -1.48), Z=7.74, P<0.000 01]. The pain rating index (PRI) score in the observation group was lower than those in the lidocaine injection control [MD=-2.17, 95%CI (-3.41, -0.93), Z=3.44, P=0.000 6] and other treatment control [low-frequency electrical stimulation, tuina, MD=-5.75, 95%CI (-9.97, -1.53), Z=2.67, P=0.008]. The present pain intensity (PPI) score in the observation group was lower than that in other treatment control [low-frequency electrical stimulation, tuina, MD=-1.04, 95%CI (-1.55, -0.53), Z=4.01, P<0.000 1]. In conclusion, compared with oral non-steroidal anti-inflammatory medication, low-frequency electrical stimulation, tuina, and electromagnetic wave irradiation combined with piroxicam gel, acupuncture is more effective in reducing pain in patients with lumbar myofascial pain syndrome; acupuncture also exhibites advantage over lidocaine injection in improving PRI score and showed better outcomes over tuina and low-frequency electrical stimulation in improving PRI and PPI scores.

ABSTRACT

Objective@#To explore the association between reading and writing posture with the occurrence of myopia in Chinese children and adolescents, so as to provide a reference for reducing its prevalence among primary and secondary school students.@*Methods@#Using data from the 2020 survey on the current status of hyperopia reserve in primary and secondary school students from six provinces/cities, namely Beijing, Zhejiang, Chongqing, Shaanxi, Liaoning, and Henan selected by multi stage stratified cluster probability sampling method during November 2020 to June 2022. A total 16 782 students who completed the optometry examination of cycloplegia according to the Children and Adolescents Myopia Screening Standard and questionnaire survey were included for analyzing analyze the association between reading and writing posture with myopia.@*Results@#The overall detection rate of myopia among primary and secondary school students was 45.7%, of which 35.0% were primary school students, 84.1% junior high school students, and 90.4% senior high school students. Poor reading and writing posture was found in 73.6% of primary and secondary school students. Adjusting for confounding factors such as gender, school period, region, outdoor time every day, and whether parents were myopic, the results of the multilevel Logistic regression showed that the following factors were positively correlated with myopia:poor reading and writing posture ( OR=1.17, 95%CI =1.07-1.28), never/occasionally reading and writing with a reading distance which was more than one foot away between the eyes and book ( OR=1.28, 95%CI=1.08-1.53, OR=1.23, 95%CI = 1.08- 1.40), teachers occasionally reminding the child of their reading and writing posture ( OR=1.13, 95%CI =1.01-1.25), and often/always reading and writing while lying down or with the face on the arm ( OR=1.15, 95%CI=1.01-1.32, OR=1.46, 95% CI = 1.17-1.82), always reading and writing with the head in the hand ( OR=1.56, 95%CI =1.20-2.01). Further, a negative correlation was detected between myopia and parents occasionally reminding their children of their reading and writing posture ( OR= 0.85 , 95%CI =0.76-0.96) ( P <0.05).@*Conclusion@#Poor reading and writing posture is a risk factor for the development of myopia in primary and secondary school students, and interventions for reading and writing posture need to be strengthened to reduce the occurrence of myopia among primary and secondary school students.

ABSTRACT

Apheresis platelets are extensively utilized in clinical practice due to high purity and minimal side effects. These platelets are primarily obtained from regular blood donors. However, there is no consensus on whether plateletpheresis leads to iron deficiency among blood donors. In recent years, increasing attention has been given to the impact of plateletpheresis on the iron nutritional status of these donors. Numerous studies have indicated a prevalence of iron deficiency among plateletpheresis donors. The process of plateletpheresis involves the loss of red blood cells, which can accumulate over time and disrupt iron metabolism, ultimately resulting in iron deficiency anemia. This condition not only affects the physical well-being of the donors but also leads to a decline in their willingness to donate blood. Blood collection and supply institutions should enhance their focus on the iron nutritional status of plateletpheresis donors and implement various measures, such as intensifying health education regarding the significance of iron supplementation, implementing programs for testing iron deficiency, considering the provision of iron supplements and extending blood donation intervals. It is crucial to prevent iron deficiency in plateletpheresis donors. These institutions should explore calculation models that can predict personalized blood donation intervals and iron supplementation strategies, and seek a balanced approach that is optimal for maintaining adequate collections while safeguarding donor health. The article comprehensively reviews literature at home and abroad on the etiology and hazards of iron deficiency in plateletpheresis donors, as well as detection methods and response measures. It serves as a foundation for developing scientific and reasonable care measures for blood donation, while also achieving personalized and scientific management and recruitment strategies for blood donors.

ABSTRACT

The multiple myeloma (MM), the second most common hematologic malignancy, is malignant proliferative disease of plasma cells. Although the application of many targeted drugs has significantly prolonged the survival time of MM patients, it is still an incurable disease. In recent years, the immunosuppression caused by interaction between tumor microenvironment(TME) and tumor cells has attracted people's attention gradually. As a kind of immunosuppressive cells in TME, regulatory T cells (Treg) play an important role in the progress of MM. Treg is related to the proliferation and metastasis of tumors, and can lead to the progress of MM by promoting the angiogenesis and generating immunosuppressive TME. In this review, we briefly summarized the latest research progress on the impact of Treg on the pathogenesis of MM.

ABSTRACT

Objective: To describe the gene mutation profile of newly diagnosed pediatric B-acute lymphoblastic leukemia (B-ALL) and analyze its effect on minimal residual disease (MRD). Methods: A total of 506 newly diagnosed B-ALL children treated in Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences from September 2018 to July 2021 were enrolled in this retrospective cohort study. The enrolled children were divided into MRD ≥1.00% group and <1.00% group according to MRD results on the 19th day since chemotherapy, and MRD ≥0.01% group and <0.01% group according to MRD results on the 46th day. Clinical characteristics and gene mutations of two groups were compared. Comparisons between groups were performed with chi-square test or Fisher's exact test. Independent risk factors of MRD results on the 19th day and the 46th day were analyzed by Logistic regression model. Results: Among all 506 patients, there were 318 males and 188 females. On the 19th day, there were 114 patients in the MRD ≥1.00% group and 392 patients in the MRD <1.00% group. On the 46th day, there were 76 patients in the MRD ≥0.01% group and 430 patients in the MRD <0.01% group. A total of 187 gene mutations were detected in 487 (96.2%) of 506 children. The most common gene mutations were signal transduction-related KRAS gene mutations in 111 cases (22.8%) and NRAS gene mutations in 99 cases (20.3%). Multivariate analysis showed that PTPN11 (OR=1.92, 95%CI 1.00-3.63), KMT2A (OR=3.51, 95%CI 1.07-11.50) gene mutations and TEL-AML1 (OR=0.48, 95%CI 0.27-0.87), BCR-ABL1 (OR=0.27, 95%CI 0.08-0.92) fusion genes and age >10 years (OR=1.91, 95%CI 1.12-3.24) were independent influencing factors for MRD ≥1.00% on the 19th day. BCORL1 (OR=2.96, 95%CI 1.18-7.44), JAK2 (OR=2.99, 95%CI 1.07-8.42) and JAK3 (OR=4.83, 95%CI 1.50-15.60) gene mutations and TEL-AML1 (OR=0.43, 95%CI 0.21-0.87) fusion gene were independent influencing factors for MRD ≥0.01% on the 46th day. Conclusions: Children with B-ALL are prone to genetic mutations, with abnormalities in the RAS signaling pathway being the most common. Signal transduction related PTPN11, JAK2 and JAK3 gene mutations, epigenetic related KMT2A gene mutation and transcription factor related BCORL1 gene mutation are independent risk factors for MRD.

ABSTRACT

@#Understanding the pattern and molecular mechanisms of tooth, maxilla and mandible development is the prerequisite for studying their regeneration. Tooth development can be divided into three stages: bud-bell stage, tooth crown development stage and tooth root development stage. During these processes, key genes show spatial and temporal expression pattern. Tooth development is a complex process involving interactions between dental epithelium and mesenchyme, precise regulations of enamel knots in cusp patterning, as well as successful eruption into the oral cavity under proper biomechanical stress and signaling transductions. The development of tooth, maxilla and mandible, all of which originate from the first branchial arch, is independent and regulates each other to form a whole during development. Any developmental defects of them will ultimately cause defects to the others. In this paper, we briefly reviewed the development of tooth, maxilla and mandible, proposed that the homeostasis of microenvironment is critical for their development. Moreover, we reviewed the role of Meckel’s cartilage, a special structure and signaling mechanism during mandible development. At last, we proposed an integrated development model of tooth, maxilla and mandible. We also hope that the regeneration of fully functional tooth, maxilla and mandible in human can be achieved based on fundamental knowledge we have gained so far.

ABSTRACT

Chronic lymphocytic leukemia (CLL) is a low-grade lymphoproliferative tumor that occurs frequently in middle-aged and elderly people. Early and precise intervention can effectively improve the clinical prognosis of CLL patients. In the past, chemotherapy was the main treatment plan. With the development of molecular biology and the continuous advent of immune targeting drugs, targeted drugs targeting B cell receptor signaling pathway have shown high clinical application value in the diagnosis and treatment path of CLL. Cellular immunotherapies such as CAR-T also offer hope for patients with relapsed and refractory CLL. Allogeneic hematopoietic stem cell transplantation and multi-drug combination have also shown remarkable results in clinical practice. The purpose of this article is to review the latest research progress in the treatment of CLL.

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of T helper cell 9 (Th9) and its cytokine interleukin 9(IL-9) in peripheral blood of patients with chronic lymphocytic leukemia(CLL).@*METHODS@#A total of 43 newly diagnosed patients with chronic lymphocytic leukemia in the First Affiliated Hospital of Xinjiang Medical University from June 2021 to June 2022 were selected as the case group. The patients were divided into Binet A group (13 cases), Binet B group (20 cases) and Binet C group (10 cases) by Binet staging system, and 20 healthy volunteers who underwent physical examinationin in our hospital in the same period served as control group. The proportion of Th9 cells in peripheral blood was detected by flow cytometry, the expression level of Th9 specific transcription factors PU.1 and IRF4 was detected by Western blot, and the expression level of serum cytokine IL-9 was detected by ELISA. The proportion of Th9, the expression of PU.1, IRF4 and IL-9 in each group were compared, and the correlation between the proportion of Th9, IL-9 and clinicopathological indexes of CLL patients was analyzed.@*RESULTS@#The proportion of Th9, the expression of PU.1, IRF4 and IL-9 in CLL group were significantly higher than those in control group (P<0.05), the proportion of Th9 and the expression of IL-9 in Binet B and C group were higher than those in Binet A group (P<0.05), but there was no significant difference in the proportion of Th9 cells between Binet B group and C group (P>0.05). The expression of IL-9 in Binet C group was significantly higher than that in Binet B group (P<0.05) . The proportion of Th9 cells and IL-9 were highly expression in patients with β2 microglobulin abnormality, IGHV unmutation, P53 abnormality and hepatosplenic lymph node enlargement(P<0.05), but not related to age and sex (P>0.05). The results of Spearman correlation analysis showed that the proportion of Th9 in patients with CLL was negatively correlated with the lymphocytic account and lymphocyte proportion(rs=-0.32,rs=-0.34). The proportion of Th9 and IL-9 were positively correlated with Binet stage, Rai stage and CLL-IPI Scoring (rs=0.79,rs=0.54,rs=0.58; rs=0.72,rs=0.63,rs=0.45), but not with WBC, CD4+ T cells and CD8+T cells (P>0.05). The proportion of Th9 was positively correlated with IL-9 (rs=0.53).@*CONCLUSION@#Th9 cells and IL-9 are abnormally highly expressed in CLL, which is related to the poor prognosis of CLL.

ABSTRACT

Objective:To analyze the application value of sakubatril valsartan in the treatment of chronic heart failure (CHF) based on cardiopulmonary test system.Methods:One hundred and thirty-five CHF patients admitted to the Affiliated Hospital of Jining Medical Collegefrom January 2019 to August 2020 were divided into the observation group (67 cases) and the control group (68cases) by random number table method. Both groups were treated with bisoprolol. The observation group was treated with the combination of sakubatril valsartan, and the control group was treated with the combination of benapril. The efficacy and cardiac function indicators of the two groups were compared. The cardiopulmonary exercise test system was used to measure the patient′s maximum exercise time (Tmax), maximum exercise Watt (Wmax), peak volume oxygen (Peak VO 2) and volume of anaerobic threshold oxygen (VO 2AT), and the incidence of adverse reactions were calculated. Results:The total effective rate in the observation group was higher than that in the control group: 92.54% (62/67) vs. 77.94%(53/68), the difference was statistically significant ( χ2 = 5.70, P<0.05). After the treatment, the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and soluble ST2 (sST2) in the observation group were lower than those in the control group: (2 000.47 ± 517.85) ng/L vs. (2 777.39 ± 812.49) ng/L, (0.33 ± 0.10) μg/L vs. (0.37 ± 0.09) μg/L, and the left ventricular ejection fraction (LVEF) was higher than that in the control group: (8.12 ± 6.44)% vs. (41.93 ± 6.73)%, the differences were statistically significant ( P<0.05). After the treatment, the left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), left ventricular mass index (LVMI), left atrial volume index (LAVI) in the observation group were lower than those in the control group: (55.47 ± 6.93) mm vs. (62.00 ± 7.18) mm, (37.14 ± 6.36) mm vs. (41.35 ± 6.43) mm, (136.76 ± 7.13) mg/m 2 vs. (140.98 ± 7.47) mg/m 2, (28.23 ± 2.59) ml/m 2 vs. (31.98 ± 2.17) ml/m 2; the Tmax, Wmax, PeakVO 2 and VO 2AT in the observation group were higher than those in the control group: (619.08 ± 65.36) s vs. (58.70 ± 52.44) s, (142.96 ± 16.05) W vs. (124.19 ± 13.38) W, (20.00 ± 5.74) ml/(min·kg) vs. (18.13 ± 3.58) ml/(min·kg), (13.89 ± 3.69) ml/(min·kg) vs. (11.23 ± 2.36) ml/(min·kg), the differences were statistically significant ( P<0.05). However, there was no statistically significant in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Sakubatril valsartan in the treatment of CHF can not only optimize the efficacy and improve cardiac function, but also benefit cardiac exercise rehabilitation of patients, and not increase the safety risk.

ABSTRACT

Objective:To compare the efficacy of sakubatril valsartan and valsartan in the treatment of patients with chronic cardiac insufficiency and the influence on zinc finger protein A20 and nuclear factor-κB (NF-κB) in peripheral bloodmononuclear cells (PBMCs).Methods:Ninety-senven patients with chronic cardiac insufficiency admitted to the Affiliated Hospital of Jining Medical College from February 2019 to January 2020 were continuously selected and randomly divided into the control group (48 cases) and the observation group (49 cases). Both groups received routine anti-heart failure according to the guidelines. The control group added with valsartan and the observation group added with sakubatril valsartan treatment. Before the treatment and after 3 months of treatment, the changes of cardiac function indexes and the changes of inflammatory markers such as hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), matrix metalloproteinase 9 (MMP-9), and N-terminal pro B-type natriuretic peptide (NT-proBNP) were compared. PBMCs was extracted to detect zinc finger protein A20 and NF-κB levels. The incidence of adverse reactions in the two groups was recorded, and the relationship between zinc finger proteins A20, NF-κB and the myocardial injury marker NT-proBNP were analyzed.Results:After 3 months of treatment, the changes of cardiac function indexes in the observation group were better than those in the control group and the levels of hs-CRP, TNF-α, MMP-9, NT-proBNP in the observation group were lower than those in the control group: (1.96 ± 0.57) mg/L vs. (2.87 ± 0.79) mg/L, (7.11 ± 1.46) μg/L vs. (8.24 ± 1.57) μg/L, (110.14 ± 10.63) μg/L vs. (129.52 ± 17.96) μg/L, (716.91 ± 105.78) ng/L vs. (965.25 ± 97.41) ng/L, there were statistical differences ( P<0.05). After 3 months of treatment, the levels of finger protein A20, NF-κB in the observation group were lower than those in the control group: (3.57 ± 1.13) % vs. (4.41 ± 1.32) %, (29.87 ± 6.58) ng/L vs. (35.71 ± 10.02) ng/L, there were statistical differences ( P<0.05). Finger protein A20 and NF-κB in patients with chronic cardiac insufficiency were positively correlated with NT-proBNP ( r = 0.487, 0.738, P<0.01). Conclusions:On the basis of conventional treatment, compared with valsartan, the addition of sakubatril valsartan, can improve the cardiac function of patients with chronic cardiac insufficiency, reduce the body′s inflammatory response, reduce the expression of myocardial injury marker NT-proBNP, inhibit the activation of PBMCs NF-κB, and reduce the level offinger protein A20.

ABSTRACT

Objective: To investigate the distribution of HIV-1 genetic subtypes and pretreatment drug resistance (PDR) among men who have sex with men (MSM) from 19 cities of 6 provinces in China. Methods: From April to November 2019, 574 plasma samples of ART-naive HIV-1 infected MSM were collected from 19 cities in Hebei, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong provinces, total ribonucleic acid (RNA) was extracted and amplified the HIV-1 pol gene region by nested polymerase chain reaction (PCR) after reverse transcription. Then sequences were used to construct a phylogenetic tree to determine genetic subtypes and submitted to the Stanford drug resistance database for drug resistance analysis. Results: A total of 479 samples were successfully amplified by PCR. The HIV-1 genetic subtypes included CRF01_AE, CRF07_BC, B, CRF55_01B, CRF59_01B, CRF65_cpx, CRF103_01B, CRF67_01B, CRF68_01B and unrecognized subtype, which accounted for 43.4%, 36.3%, 6.3%, 5.9%, 0.8%, 0.8%, 0.4%, 0.4%, 0.2% and 5.5%, respectively. The distribution of genetic subtypes among provinces is statistically different (χ2=44.141, P<0.001). The overall PDR rate was 4.6% (22/479), the drug resistance rate of non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, and protease inhibitors were 3.5% (17/479), 0.8% (4/479) and 0.2% (1/479), respectively. The PDR rate of recent infections was significantly higher than that of long-term infections (χ2=4.634, P=0.031). Conclusions: The HIV-1 genetic subtypes among MSM infected with HIV-1 from 19 cities of 6 provinces in China are diverse, and the distribution of subtypes is different among provinces. The overall PDR rate is low, while the PDR rate of recent infections was significantly higher than that of long-term infections, suggesting the surveillance of PDR in recent infections should be strengthened.

ABSTRACT

Parkinson′s disease (PD) is a complex neurodegenerative disorder typically known for characteristic loss of dopaminergic neurons in the substantia nigra striatum. To date, therapeutic approaches for PD are still lacking due to the multifactorial etiology and complicated pathogenesis. Thus, the studies relative to the biological mechanisms and drug development of PD are the hotspot in this field. In recent years, numerous studies suggest that the PD is associated with mitochondrial dysfunction which is affected by multiple genes regulation. Genome-wide association studies have proved that monogenic PD gene locus is associated with mitochondrial dysfunction. Although there are many studies on how PD pathogenic genes regulate mitochondrial dysfunction then affect neuronal physiological function and ultimately lead to the PD, the effects of mutations in PD-associated genes on mitochondrial dysfunction remain not fully understood. In this review, the literature discussing the mechanisms of mitochondrial dysfunction in the context of PD was summarized with the aim to implicate the potential opportunities for therapeutically targeting mitochondria.

ABSTRACT

Folate receptor(FR)overexpression occurs in a variety of cancers,including pancreatic cancer.In addi-tion,enhanced macropinocytosis exists in K-Ras mutant pancreatic cancer.Furthermore,the occurrence of intensive desmoplasia causes a hypoxic microenvironment in pancreatic cancer.In this study,a novel FR-directed,macropinocytosis-enhanced,and highly cytotoxic bioconjugate folate(F)-human serum albumin(HSA)-apoprotein of lidamycin(LDP)-active enediyne(AE)derived from lidamycin was designed and prepared.F-HSA-LDP-AE consisted of four moieties:F,HSA,LDP,and AE.F-HSA-LDP presented high binding efficiency with the FR and pancreatic cancer cells.Its uptake in wild-type cells was more extensive than in K-Ras mutant-type cells.By in vivo optical imaging,F-HSA-LDP displayed prominent tumor-specific biodistribution in pancreatic cancer xenograft-bearing mice,showing clear and lasting tumor localization for 360 h.In the MTT assay,F-HSA-LDP-AE demonstrated potent cytotoxicity in three types of pancreatic cancer cell lines.It also induced apoptosis and caused G2/M cell cycle arrest.F-HSA-LDP-AE markedly suppressed the tumor growth of AsPc-1 pancreatic cancer xenografts in athymic mice.At well-tolerated doses of 0.5 and 1 mg/kg,(i.v.,twice),the inhibition rates were 91.2%and 94.8%,respectively(P<0.01).The results of this study indicate that the F-HSA-LDP multi-functional bioconjugate might be effective for treating K-Ras mutant pancreatic cancer.
