ABSTRACT

Objective To analyze and compare the epidemiological characteristics of imported malaria in Jiaozuo City before and after malaria elimination, so as to provide insights into the malaria surveillance during the post-elimination stage and prevention of re-establishment of imported malaria. Methods Data pertaining to the epidemic situation and individual investigation of malaria in Jiaozuo City before (from 2010 to 2016) and after malaria elimination (from 2017 to November, 2020) were captured from the National Notifiable Disease Reporting System and the Information System for Parasitic Diseases Control and Prevention of Chinese Center for Disease Control and Prevention and were analyzed statistically. Results A total of 74 imported malaria cases were reported in Jiaozuo City from 2010 to 2021. Imported cases were predominantly Plasmodium falciparum malaria cases in Jiaozuo City before and after malaria elimination, and there was no significant difference in the proportion of malaria parasite species (χ2 = 0.234, P > 0.05). The imported malaria cases was predominantly reported in Wuzhi County, and was identified in overseas male farmers and businessmen at ages of 20 to 59 years, while the greatest number of imported malaria cases was reported in June and December before and after malaria elimination. The imported malaria cases predominantly acquired malaria parasite infections in sub-Saharan African countries; however, the proportion of imported malaria cases returning from Southeast Asian counties increased after malaria elimination than before malaria elimination (χ2 = 5.989, P < 0.05). The longest duration from onset to definitive diagnosis of malaria reduced from 27 days before malaria elimination to 18 days after malaria elimination, and the median duration reduced from 3 days to 2 days, while the proportion of definitive diagnosis of malaria increased from 60.47% before malaria elimination to 83.87% after malaria elimination (χ2 = 4.724, P < 0.05). In addition, the proportion of malaria cases definitively diagnosed and reported by medical institutions increased after malaria elimination than before malaria elimination (χ2 = 5.406, P < 0.05). Conclusions The imported malaria patients were predominantly P. falciparum malaria cases in Jiaozuo City during 2010 to 2021, and the patient’s medical care-seeking awareness and medical staff’s diagnosis and treatment ability have improved after malaria elimination. It is necessary to strengthen and improve malaria surveillance and response system and prevent the re-establishment of overseas imported malaria.

ABSTRACT

Objective:To compare the safety and effectiveness of direct stenting versus deferred stenting for the treatment of acute ST segment elevation myocardial infarction(STEMI)with a high thrombus load in patients aged 60 years and above.Methods:In this study, we analyzed 252 elderly STEMI patients with a high thrombus load(thrombus score ≥ 4 points)who received percutaneous coronary intervention(PCI)at Beijing Anzhen Hospital Affiliated or at the Affiliated Hospital of Beihua University from January 2015 to December 2018.They were divided into the direct stent group(n = 126)and the deferred stent group(n = 126)according to whether the stent was inserted immediately or not.Baseline information, surgical information, clinical outcomes and major adverse cardiac events were compared between the two groups at 1 year follow-up.Cox regression analysis was used to determine whether deferred stent implantation was a prognostic factor.Results:There were no significant differences in the distribution of infarct-related arteries, time from onset to balloon dilatation, thrombus load scores and the number of stents between the two groups(all P> 0.05). The diameter and length of the stent were(3.20 ± 0.47)mm and(18.33 ± 5.06)mm in the deferred stent group and(3.03 ± 0.50)mm and(22.60 ± 5.08)mm in the direct stent group, respectively, with a significant difference between the two groups( t=2.926, 6.678, P=0.004, 0.000). The incidences of slow blood flow, distal embolism and low myocardial perfusion staining in the deferred stent group were 2.38%(3/126), 3.17%(4/126)and 2.38%(3/126), respectively, significantly lower than those in the direct stent group, which were 15.87%(20/126), 24.60%(31/126)and 20.63%(26/126), respectively( χ2=13.827, 24.188, 20.614, all P=0.000). The left ventricular ejection fraction(LVEF)at 1 year in the deferred stent group was (0.60±0.05)%, significantly higher than that in the direct stent group(0.57±0.05)%( t=3.859, P=0.000). There was no significant difference in major adverse cardiac events between the two groups at 1 year follow-up( P> 0.05). Cox regression analysis results showed that deferred stent implantation was not a factor affecting the clinical outcome( HR=0.827, 95% CI: 0.288~2.372, P=0.724). Conclusions:Deferred stent implantation and direct stent intervention are equally safe and effective for STEMI patients aged over 60 with a high thrombus load if admitted to the hospital within 12 hours after onset.Deferred stent implantation can significantly improve the infarct-related artery blood flow classification, reduce the distal embolism rate, increase the grade 3 rate of myocardial perfusion staining, increase the diameter of the stent, reduce the length of the stent and improve left ventricular ejection fraction.

ABSTRACT

Gemcitabine (GEM) is a commonly used drug in the clinical treatment of non-small cell lung cancer. Due to the accumulation of cells mediating immune escape and T cell depletion after chemotherapy, tumor microenvironment (TME) tends to be immunosuppressive status, which ultimately leads to tumor metastasis. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Jiangsu Provincial Academy of Chinese Medicine. Therefore, we observed the immunomodulatory effects of micro-particulate Ganoderma lucidum spore β-glucan (PGSG) on macrophages in vitro experiments. Next, mice subcutaneous Lewis lung cancer models were established to observe the anti-tumor effects of PGSG through oral administration of PGSG combined with GEM. Flow cytometry analysis was used to analyze the ratio of anti-tumor T cells in tumors and spleen, as well as the proportion of myeloid-derived suppressor cells (MDSC), tumor-associated macrophages (TAM) and regulatory cells (Tregs). The results showed that PGSG can up-regulate the expression of major histocompatibility antigens (MHC-II), CD40, CD86 and CD80 on the surface of macrophages, enhance the ability to phagocytosis of neutral red and further mediate the release of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4) and interleukin-10 (IL-10). In vivo experiments, combined administration can significantly decrease the volume and weight of tumors, reduce the ratio of MDSC (CD11b+Gr-1+), M-MDSC (CD11b+Ly6G-Ly6Chigh) and Treg (CD4+Foxp3+). At the same time, PGSG promoted the conversion of M2 (F4/80+CD206+) to M1 (F4/80+MHC-II+) and enhanced the response of helper T cell-1 (Th1) (CD4+IFN-γ+) and cytotoxic T lymphocyte (CTL) (CD8+IFN-γ+), which is of great significance for killing tumors. These results suggest that PGSG can regulate innate and adaptive antitumor immune responses, reshape the immunosuppressive microenvironment and enhance the anti-lung cancer effect of GEM.

ABSTRACT

Objective:To evaluate the effect of paclitaxel on the mast cell-CCL2-macrophage axis in rats with pulmonary hypertension.Methods:Thirty SPF-grade healthy male Sprague-Dawley rats, aged 8-10 weeks, weighing 180-220 g, were divided into 3 groups ( n=10 each) using a random number table method: control group (group C), pulmonary hypertension group (group PH), and paclitaxel group (group PTX). The model of pulmonary hypertension was established by subcutaneous injection of monocrotaline 60 mg/kg in rats.At 25 days after establishing the models, paclitaxel 2 mg/kg was injected via the tail vein once every four days, for 4 times in total in group PTX.The equal volume of normal saline was injected in the remaining 2 groups.The mean pulmonary artery pressure (mPAP) was performed at 40 days after establishing the model.The heart was removed and dried, the right ventricle (RV) and left ventricle plus ventricular septum (LV+ S) was weighed, and the Fulton index [RV/(LV+ S)] was calculated.The inferior lobe of left lung was taken, the ratio of media wall thickness of pulmonary vessels was calculated by HE staining, the number of Tryptase + , CD68 + , CD163 + , and Ki67 + cells was recorded by immunohistochemistry, the mean value was calculated, the percentage of Ki67-positive cells in blood vessels was recorded, and the proportion of muscularized blood vessels was calculated.The content of CCL2 was measured by enzyme-linked immunosorbent assay, and the expression of cleaved caspase-3 and Cyclin D1 was detected by Western blot. Results:Compared with group C, the mPAP, Fulton index, ratio of media wall thickness, proportion of muscularized blood vessels, the number of Tryptase + , CD68 + and CD163 + cells and percentage of Ki67 + cells were significantly increased, and the expression of cleaved caspase-3 was down-regulated in PH and PTX groups ( P<0.05), the expression of Cyclin D1 was significantly up-regulated in group PH ( P<0.05), and no significant change was found in group PTX ( P>0.05). Compared with group PH, the mPAP, Fulton index, ratio of media wall thickness, percentage of muscularized blood vessels, the number of Tryptase + , CD68 + and CD163 + cells and percentage of Ki67 + cells were significantly decreased, the expression of CCL2 and Cyclin D1 was down-regulated, and the expression of cleaved caspase-3 was up-regulated in group PTX ( P<0.05). Conclusion:The mechanism by which paclitaxel alleviates pulmonary hypertension is related to inhibiting the mast cell-CCL2-macrophage axis in rats.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a Chinese pedigree affected with X-linked hereditary Alport syndrome.@*METHODS@#Next generation sequencing was carried out for the pedigree. Candidate variant was validated by Sanger sequencing. Pathological changes of renal basement membrane and expression of COL4A5 protein were analyzed by renal biopsy and immunofluorescence assay, respectively.@*RESULTS@#All patients from the pedigree manifested progressive renal damage, gross hematuria, proteinuria and nephrotic syndrome. Renal biopsy of the proband revealed thickening of the basement membrane. No expression of the COL4A5 gene was detected by immunofluorescence. High-throughput sequencing and Sanger sequencing indicated that the proband has carried a c.3706delC (p.1236Pfs*69) variant in exon 41 of the COL4A5 gene. The same variant was also found in his mother and two brothers whom were similarly affected.@*CONCLUSION@#The novel c.3706delC (p.1236Pfs*69) variant of the COL4A5 gene probably underlay the pathogenesis of X-linked hereditary Alport syndrome in this pedigree. Above findings have enriched the spectrum of COL4A5 gene variants and provided a basis for the diagnosis and genetic counseling for the pedigree.

ABSTRACT

Fermentative production of amino acids is one of the pillars of the fermentation industry in China. Recently, with the fast development of metabolic engineering and synthetic biology technologies, the metabolic engineering for production of amino acids has been flourishing. Conventional forward metabolic engineering, reversed metabolic engineering based on omics data and in silico simulation, and evolutionary metabolic engineering mimicking the natural evolution, have shown increasingly promising applications. A series of highly efficient and robust amino acids-producing strains have been developed and applied in the industrial production of amino acids. The increasingly fierce market competition has put forward new requirements for strain breeding and selection, such as developing high value-added amino acids, dynamic regulation of cellular metabolism, and adapting to the requirements of new process. This review summarizes the advances and prospects in metabolic engineering for the production of amino acids.

ABSTRACT

Objective To analyze the clinical manifestation, diagnosis and pathological features of abdominal ectopic spleen (AES) cases. Methods The clinical and pathological characteristics were retrospectively analyzed along with the followup data of patients diagnosed as AES in the Changhai Hospital affiliated to Naval Medical University from Jan. 2013 to Dec. 2018. Results A total of 13 cases of AES were diagnosed, of whom 7 cases (53.8%) were found due to medical examination, and only one case was diagnosed before operation, while the rest were considered as having tumor of the abdominal organ near the mass. Out of the 13 cases, the AES in 6 cases were located at the pancreas tail. The surgical excision samples showed an appearance of nodular lesion with clear contour, and the structure of spleen parenchyma could be identified under microscope. Among the 13 cases, spleen trabecular and obvious central arterioles were absent in 2 cases with history of surgery, while the rest 11 cases shared the pathological features of spleen trabecular, central arterioles and secondary follicles. All the 13 patients survived except one died due to progression of gastric cancer and another one missing of follow-up. Conclusions The AES lacks specific clinical features, which requires antidiastole with abdominal tumors. It is inferred from clinicopathological features that splenosis may differ from accessory spleen, that is, splenosis may lack typical spleen white pulp.

ABSTRACT

Objective: To observe the effects of Aconitum carmichaelii on serum metabolites in mice by metabolomics technology, and to explore biomarkers and metabolic pathways and targets related to its treatment of various ailments such as cardiovascular diseases, in order to uncover its molecular mechanism of efficacy. Methods: Twenty male mice were randomly divided into two groups, and A. carmichaelii decoction and distilled water were orally administered with the dose of 15 mL/(kg∙d) for consecutive 4 d respectively. Collected blood samples of each group were analyzed using UPLC-MS/MS technology, and data pattern recognition was performed using PCA, PLS-DA and other analytical methods. Meanwhile, differential metabolites were screened out based on VIP greater than 1 and manual integral calculation. The differential metabolites were used for pathway analysis. Network modular analysis and targets screening were performed by Cytoscape and MetScape. Results: When performing data pattern recognition, the aconite group and the control group could be completely separated. A total of 18 differential metabolites were screened out, and their contents were up-regulated. Pathway analysis was performed to obtain five related pathways, namely linoleic acid metabolism, arachidonic acid metabolism, starch and sucrose metabolism, nicotinate and nicotinamide metabolism, and inositol phosphate metabolism. Fourteen modules were obtained using the network analysis, the largest two of which were arachidonic acid metabolism pathway and linoleic acid metabolism pathway. The degree of arachidonic acid (59), linoleic acid (55), nicotinamide (26), and palmitic acid (11) were greater than the mean value (8.010) in the network, and the related pathways were arachidonic acid metabolism, linoleic acid metabolism, nicotinate and nicotinamide metabolism, and saturated fatty acid beta-oxidation pathway respectively. A total of 26 genes were screened out, all of which belonged to the cytochrome P450 enzyme system. Conclusion: A. carmichaelii may affect arachidonic acid metabolism by acting on CYP450, thereby improving the body's energy metabolism and producing therapeutic effects.

ABSTRACT

OBJECTIVE@#To investigate the surgical technique and efficacy of large retractor assisted maintenance of proximal femoral nail antirotation(PFNA) in the treatment of femoral intertrochanteric fracture in the absence of a retractor.@*METHODS@#A total of 55 patients with intertrochanteric fractures treated with PFNA internal fixation were selected from April 2012 to December 2016 with a large retractor assisted in maintaining reduction, including 18 males and 37 females with an average age of 75.65 years old ranging from 47 to 90 years old; 31 cases were on the left side and 24 on the right side. All patients had preoperative ipsilateral hip pain, limited mobility, ipsilateral lower extremity extreme external rotation malformation or accompanied by shortening, and preoperative radiographs were clearly diagnosed intertrochanteric fractures. The operative time, intraoperative blood loss, and intraoperative fluoroscopy time were recorded. Postoperative hip function were evaluated.@*RESULTS@#The average operation time was 45.35 min, the average intraoperative blood loss was 117.64 ml and the mean intraoperative fluoroscopic time was 3.42 min. All the fractures were well restored. All patients were followed up from 12 to 24 months with an average of 16.43 months. All the intertrochanteric fractures were bone healed without hip varus deformity, and there were no complications such as internal fixation loosening and fracture. According to Harris hip function score criteria, the results were excellent in 40 cases, good in 8 cases, fair in 5 cases, poor in 2 cases.@*CONCLUSIONS@#Large retractor assisted in maintaining the use of PFNA under reposition can fix various types of femoral intertrochanteric fractures. It has simple requirements for surgical position, low equipment requirements, short operation time, less trauma, reliable fixation, and good postoperative recovery. The surgical procedure can be carried out in a primary hospital without a traction bed.

ABSTRACT

OBJECTIVE@#Small ubiquitin-related modifiers (SUMOs) are a group of post-translational modification proteins extensively expressed in eukaryotes. Abnormal SUMOylation can lead to the development of various diseases. This article summarizes the progress on research of the role of SUMOs in various types of kidney diseases to further increase the understanding of the regulatory functions of SUMOylation in the pathogenesis of kidney diseases.@*DATA SOURCES@#This review was based on articles published in the PubMed databases up to January 2018, using the keywords including "SUMOs," "SUMOylation," and "kidney diseases."@*STUDY SELECTION@#Original articles and critical reviews about SUMOs and kidney disease were selected for this review. A total of 50 studies were in English.@*RESULTS@#SUMO participates in the activation of NF-κB inflammatory signaling pathway, playing a central regulatory role in the inflammation and progression of DN, and the secretion of various chemokines in AKI. SUMO involves in the regulation of TG2 and Nrf2 antioxidant stress, affecting renal tubular injury in AKI. SUMO affects the MAPK/ERK pathway, regulating intracellular signal transduction, modulating the transcription and expression of effector molecules in DN. SUMO contributes to the TGF-β/Smad pathway, leading to fibrosis of the kidney. The conjugate combination of SUMO and p53 regulates cell proliferation and apoptosis, and participates in the regulation of tumorigenesis. In addition, SUMOylation of MITF modulates renal tumors secondary to melanoma, Similarly, SUMOylation of tumor suppressor gene VHL regulates the occurrence of renal cell carcinoma in VHL syndrome.@*CONCLUSIONS@#Tissue injury, inflammatory responses, fibrosis, apoptosis, and tumor proliferation in kidney diseases all involve SUMOs. Further research of the substrate SUMOylation and regulatory mechanisms of SUMO in kidney diseases will improve and develop new treatment measures and strategies targeting kidney diseases.

ABSTRACT

Objective@#To examine the influences of overweight and obesity on left ventricular hypertrophy (LVH) in school-aged children, and to provide the scientific reference for early screening and making interventional measures for the damage of their heart structure.@*Methods@#Based on a cross-sectional survey conducted in Jinan between 2012 and 2014, a total of 327 students aged 6-17 who had hypertension were selected. Covariance analysis and trend chi-square test were used to analyze the trend of left ventricular mass index (LVMI) and abnormal LVH rate across different categories of body mass index (BMI) after adjusted for age, gender and blood pressure (BP). Logistic regression analysis was used to evaluate the effects of overweight and obesity on LVH.@*Results@#After adjusting for age, gender and BP, covariance analysis indicated that with the increase of BMI, the levels of LVMI [(26.8±1.8, 34.7±1.5, 40.1±0.9)g/m2.7] and prevalence of LVH (80.%, 22.4%, 41.4%) showed upward trends (F/χ2=22.68, 24.28, P<0.05). Compared with normal weight school-aged children, the risk of LVH increased for overweight and obese school-aged children, and the odds ratios (95% confidence intervals) were 3.83 (1.16-12.61) and 9.18 (3.10-27.19), respectively.@*Conclusion@#Overweight and obesity significantly increase the risk of LVH in school-aged children. Effective prevention and treatment of overweight and obesity may reduce the risk of abnormal cardiac structure in school-aged children.

ABSTRACT

Objectives:To investigate the relationship between the changes of blood lipids and the progression of non-target lesions after percutaneous coronary intervention (PCI). Methods:Consecutive patients hospitalized in Beijing Anzhen Hospital of Capital Medical University from January 2013 to December 2016 for acute coronary syndrome (ACS) with coronary angiography evidence of multivessel disease, in which single vessel disease (Target lesion) stenosis> 75%, and the single vessel was treated with PCI, and the remaining non-target lesions with stenosis <50%, and re-hospitalized due to chest pain within 6 to 24 months, were eligible for this study. A total of 3 071 patients met the inclusion criteria were enrolled in this study. According to the quantitative analysis of 3-dimensional reconstruction coronary angiography (QCA), patients were divided into A, B groups:group A (n=1 541) refers patients with progressive non-target lesions (stenosis from <50% to >75%), group B (n=1 530) refers progression-free non-target lesions (stenosis <75%). Blood lipid levels at two hospitalizations, blood lipid changes and the lipid control rate, LDL-C control rate = (<1.8 mmol/L patients + LDL-C decline>50%)/ total number of patients, were compared between the two groups. Results:The LDL-C level [group A:(2.68 ± 0.88) mmol/L vs group B:(2.72 ± 0.92) mmol/L, P=0.509] and the LDL-C control rate (group A:14% vs group B:13.1%, P=0.476) at the first hospitalization were similar between the two groups. At the second hospitalization, the level of LDL-C was significantly lower in group B than that in group A ([1.91 ± 0.64] mmol/L vs [2.17 ± 0.76] mmol/L, P<0.001). The LDL-C control rate was significantly higher in group B than in the group A (43.66% vs 35.37%, P<0.001). Moreover, the reduction of total cholesterol and triglyceride was more significant in group B ([0.85±0.81] mmol/L and [0.24±1.58] mmol/L) compared to group A ([0.58±1.01] mmol/L and [0.17±1.37] mmol/L, both P<0.001) at the second hospitalization. Multivariate Logistic regression analysis showed that age, diabetes, hypertension, smoking, family history of coronary heart disease, hyperlipidemia and non-target lesions were not associated with progression of non-target lesions; LDL-C level at the second hospitalization (OR=1.686, 95%CI:1.508~1.885; P<0.001) and regular statin use after PCI (OR=0.275, 95%CI:0.230~0.328; P<0.001) were associated with progression of non-target lesions. Conclusions:Our results indicate that poor lipid control post PCI is one of the reasons leading to the progression of non-target lesions.

ABSTRACT

Objective To explore the protective effect of gallic acid in Phyllanthus emblica on high glucose-induced apoptosis of pancreatic islet β cells, and to provide a reference for the discovery of natural compounds for the treatment of diabetes. Methods In vivo experimental model, wistar male rats were used as in vivo subjects and 50 mg/kg STZ was injected intraperitoneally. After the model was successfully established, 25 mg/kg of gallic acid was given orally, and the positive drug was Sitagliptin. After 4 weeks of administration, the blood was taken and the pancreas was removed for HE staining. Western blot was used to measure the expression of NLRP3 and TXNIP in pancreatic tissue in high sugar state. In vitro model, insulinoma cell line INS-1 cells were used as in vitro targets to establish high levels. In sugar-induced apoptosis model, INS-1 cells were cultured in glucose-free RPMI 1640 complete medium supplemented with 25 mmol/L glucose. Gallic acid was used as the test sample. Experiments were divided into normal controls, high-sugar models, and low, medium and high levels of gallic acid groups. The cell viability was measured by MTT assay. The mRNA expression of NLRP3 and TXNIP in INS-1 cells was detected by QPCR and Western blot, and the expression of NLRP3 and TXNIP protein was detected.Results (1) INS-1 cells were cultured in a medium with glucose concentration of 25mmol/L for 48h, and the apoptosis rate was increased compared with the control group (P<0.01), indicating that the apoptosis model was established successfully under high glucose conditions. (2) 10, 5, and 2.5 μmol/L GA were used to treat the control group and the high glucose model group cells respectively. The survival rate of the control group did not change significantly (P>0.05) . Compared with the control group, the expression of NLRP3 and TXNIP in INS-1 cells in the high glucose model group was significantly different (P<0.05);the protein expression level was significantly downregulated after GA treatment, and there was a statistical difference (P<0.05) . Compared with the control group, the expression of NLRP3 protein in INS-1 cells in the high glucose model group was statistically different (P<0.01), and the protein expression level was significantly downregulated after GA treatment (P<0.01) ; The protein expression level was up-regulated (P<0.05);the protein expression level after GA treatment was significantly down-regulated (P<0.05); (4) The expression of NLRP3 and TXNIP mRNA in INS-1 cells was increased in the high glucose model group compared with the control group (P<0.01) ; The expression of protein was significantly down-regulated after GA treatment (P<0.01) . Conclusion The cells were cultured for 48 h in glucose-free RPMI 1640 complete medium supplemented with 25 mmol/L glucose. GA has no effect on the proliferation of normal INS-1 cells. GA protects INS-1 cells from apoptosis under high glucose conditions. The mechanism may be related to GA down-regulation of NLRP3 and TXNIP gene expression.
