ABSTRACT

Objective To analyze the changes of CD4+ T cell numbers at different periods of antiviral therapy in HIV-infected and AIDS patients (HIV/AIDS) in Yichang City. Methods The relevant information was retrieved from the National AIDS Comprehensive Prevention Information System-Antiretroviral Treatment Management Database. Changes in the number of CD4+ T cells were analyzed in HIV/AIDS patients who started receiving highly active antiretroviral therapy (HAART) and continued the treatment for 3 years from January 1, 2003 to December 31, 2017 in Yichang. Results The number of CD4+T lymphocytes in 550 HIV/AIDS cases increased significantly at various time points within 3 years after treatment, and increased with the increase of treatment time(F=100.20,P<0.001). The CD4+T cell counts of different baseline level groups were statistically different before and after treatment(F=8.57,P<0.01). The CD4+ T cell counts of patients who started treatment at age of 15-30 years old increased faster than those who started treatment at age of over 30 years old(F=1.27,P<0.05). Conclusion HAART has a significant effect on the increase of CD4+T cells, and the early treatment is more effective. Early detection, diagnosis and treatment should be promoted, and anti-viral treatment should be actively carried out.

ABSTRACT

The present study explored the potential mechanism of Jingfang Granules in relieving alcohol and protecting liver by network pharmacology and molecular docking and verified the effects and related pathways by animal experiments. The active components of Jingfang Granules were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Targets of drugs and diseases were obtained from PubChem, Swiss Target Prediction and CTD. The common targets were uploaded to STRING to plot the protein-protein interaction(PPI) network. The core targets were screened out and the target organs were identified by Bio GPS and Metascape, followed by Gene Ontology(GO) analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis of common targets. The acute drunk mouse model was established and the effects of Jingfang Granules on serum ethanol level and the expression of proteins related to the phosphatidylinositol 3-kinase(PI3 K)/protein kinase B(Akt) signaling pathway in the liver tissue of mice were observed. A total of 187 active components of Jingfang Granules were obtained, including 47 common targets with alcoholic liver injury. GO enrichment analysis and KEGG pathway analysis showed that Jingfang Granules might play the role of relieving alcohol and protecting liver through the PI3 K-Akt signaling pathway. The drug-component-target and component-target-pathway networks revealed that the important active components of Jingfang Granules in relieving alcohol and protecting liver included quercetin, 5-O-methylvisamminol, glyasperin M, glyasperin B and hederagenin. Molecular docking showed that the active components had a good affinity with AKT1, EGFR, ESR1 and PTGS2. Experimental results showed that Jingfang Granules(15 and 10. 5 g·kg-1) could significantly reduce the content of serum ethanol in mice and up-regulate the protein expression ratios of p-PI3 K/PI3 K and p-Akt/Akt in the liver tissue. Jingfang Granules could relieve alcohol and protect liver through multi-component and multitarget, and the mechanism may be related to the activation of the PI3 K-Akt signaling pathway.

ABSTRACT

OBJECTIVE@#To investigate the relationship between spine-pelvic sagittal parameters and clinical efficacy before and after oblique lumbar interbody fusion(OLIF).@*METHODS@#A retrospective analysis of clinical data of 65 patients with lumbar degenerative diseases treated with OLIF were performed from July 2017 to July 2018. There were 26 males and 39 females aged from 33 to 79 years old with an average of (62.72±10.23) years old. Oswestry Disability Index (ODI) and visual analogue scale (VAS) before and at the latest follow up were evaluated. Disc height (DH) and spine- pelvic sagittal parameters of the surgical segment were measured before and at the latest follow- up, including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and lumbar lordosis (LL). According to the difference of PI-LL, it was judged whether PI and LL match and the patients were grouped, PI-LL ranged from -9° to 9° was set as matching group, and PI-LL less than -9° or larger than 9° was set as mismatching group. The spine-pelvic sagittal parameters were analyzed before and at the latest follow-up of OLIF in patients with lumbar degenerative diseases, and the correlation between changes and clinical efficacy was compared.@*RESULTS@#All patients were followed up from 8 to 20 months with an average of (14.20±3.68) months. Operation time was (91.54±25.97) min, intraoperative blood loss was (48.15±10.14) ml, and the hospitalization time ranged from 6 to 19 days with an average of (9.28± 2.50) days. Totally 84 surgical levels, 46 patients were single segment and 19 patients were double segments. VAS and ODI score were improved from (4.88±0.99) point, (67.60±13.73) % preoperatively to (2.85±1.30) points, (30.57±6.48) % at the latest follow-up. There were significant differences in VAS and ODI scores between before and at the latest follow-up. The sagittal parameters of LL, PT, SS, PI, PI -LL and the surgical level DH were (42.80 ±16.35)° , (23.22 ±10.91)° , (26.95 ± 13.30)°, (50.22±14.51)°, (7.53±16.13) °, (0.91±0.29) cm preoperatively and improved to the latest follow-up (49.95± 12.82) °, (17.94±9.24) °, (33.71±12.66) °, (51.65±10.26) °, (1.68±17.00) °, (1.20±0.40) cm;there were statistical differences in LL, PT, SS, PI-LL, DH before operation and at the latest follow up, while no difference in PI. LL of preoperative PI-LL in matched group was (48.76±11.09)° , and (38.00±18.37)° in PI-LL mismatch group, there was difference between two groups. There were no differences in VAS, ODI, PT, SS, PI and DH between two groups. At the latest follow-up, ODI between PI-LL matched group and PI-LL mismatched group were (29.40±5.93)% and (32.86±7.02)% respectively, and had difference in ODI between two groups;while there were no significant differences in VAS, LL, PT, SS, PI, and DH. Pearson correlation analysis showed preoperative PT-LL was positively correlated with VAS;PT was positively correlated with ODI at the latest follow-up.@*CONCLUSION@#OLIF has a good surgical effect on lumbar degenerative diseases, and could change spine-pelvic sagittal parameters of patient to a certain extent, and further restoring the balance of the sagittal plane of lumbar spine.

ABSTRACT

This present study aimed to explore the molecular mechanism of Erzhi Wan(a prescription of nourishing Yin and toni-fying liver and kidney) in treatment of aging by network pharmacology. The active constituents and target proteins of Erzhi Wan were searched from Traditional Chinese Medicine Systems Pharmacology Database(TCMSP) and PubChem databases respectively. Aging-related genes were searched from Gene and HAGR databases. Based on the Ingenuity Pathway Analysis(IPA), we analyzed the common molecular network, biological pathway and interaction sites between these two parts, and verified some of them by Western blot. Twelve active constituents of Erzhi Wan were screened by TCMSP databases, 69 protein targets were predicted through PubChem, and 148 aging-related genes were found in Gene and HAGR databases. IPA comparison showed that the molecular networks of these two were complex, with diversity of biological functions. The common pathways involved 292 pathways, mainly related to tumors. They acted on hypoxia inducible factor-1α gene(HIF1α), nuclear factor-E2 related factor(Nrf2/NFE2 L2), tumor necrosis factor(TNF) and other sites. Western blot results suggested that Erzhi Wan could down-regulate the expression of HIF1α, with statistical difference(P<0.05). It was concluded that, Erzhi Wan could intervene aging through improving pseudo-hypoxic microenvironment and inflammation. The molecular mechanism of Erzhi Wan in delaying aging was preliminarily revealed, which laid a foundation for further stu-dying the anti-aging mechanism of Erzhi Wan, and also provided a reference for the compatibility mechanism and extended application of Chinese medicine compounds.

ABSTRACT

West Nile virus (WNV) causes West Nile fever and West Nile encephalitis. Because infection by WNV creates serious public health problems, its simple, rapid, and visual detection is very important in clinical practice, especially in resource-limited laboratories. We have developed a rapid, specific, and highly sensitive internally controlled reverse transcription recombinase-aided amplification (RTRAA) assay to detect WNV, using both real-time fluorescence and the lateral flow dipstick (LFD) at 39.0 °C for 30 min. The analytical sensitivity of the RT-RAA assay was 10 plasmid copies and 1.6 pfu per reaction with real-time fluorescence, and 1,000 plasmid copies per reaction with the LFD. No crossreaction with other control viruses was observed. Compared with the RT-qPCR assay, the RT-RAA assay demonstrated 100% sensitivity and 100% specificity for WNV.

ABSTRACT

OBJECTIVE@#Tick-borne encephalitis virus (TBEV) is an emerging pathogen in Europe and North Asia that causes tick-borne encephalitis (TBE). A simple, rapid method for detecting TBEV RNA is needed to control this disease.@*METHODS@#A reverse-transcription recombinase-aided amplification (RT-RAA) assay was developed. This assay can be completed in one closed tube at 39 °C within 30 minutes. The sensitivity and specificity of RT-RAA were validated using non-infectious synthetic RNA representing a fragment of the NS5 region of the wild-type (WT) TBEV genome and the Senzhang strain. Additionally, 10 batches of tick samples were used to evaluate the performance of the RT-RAA assay.@*RESULTS@#The analytical limit of detection of the assay was 20 copies per reaction of the TBEV synthetic transcript and 3 plaque-forming units (pfu) per reaction of TBEV titers. With the specific assay, no signal due to other arboviruses was observed. Of the 10 batches of tick samples obtained from the Changbai Mountains of China, three were TBEV-positive, which was consistent with the results of the quantitative real-time PCR assay.@*CONCLUSION@#A rapid, highly sensitive, specific, and easy-to-use method was developed for the detection of the TBEV Far-Eastern subtype.

ABSTRACT

Objective To observe the relationship of IL-17 and arterial blood gas, fibrin fragment D (D-D) in patients with both pulmonary embolism (PE) and obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods We collected 20 patients with both PE and OSAHS and 43 patients with only PE who hospitalized in the first ward of pneumology department of the Second Affiliated Hospital of Kunming Medical University, then measured D-D, IL-17 in venous blood and arterial blood gas and recorded them to analysis.Re s ults PO2 in patients with both PE and OSAHS was significantly lower than that in patients with only PE, while D-D and IL-17 of the latter were markedly lesser than the former. Conclus ions The expression of IL-17 between the 2 groups of patients has statistically significant difference. What's more, the expression of IL-17 is positively associated with hypercoagulability and Body Mass Index (BMI), and the result shows a negative relation between arterial blood oxygen partial pressure and IL-17, suggesting that IL-17 may be relate to the common progress of PE and OSASH. Thus, IL-17 can be used in the detection of patients with both PE and OSASH

ABSTRACT

Objective To explore the value of using sPESI score and hs-TnT in the evaluation of short-term prognosis in hemodynamically stable pulmonary embolism. Methods We collected 99 patients with hemodynamically stable PE from our department. According to the sPESI score and hs-TnT, patients were divided into high risk group (sPESI score≥1) and low risk group (sPESI score=0), positive group (hs-TnT≥0.014 ng/mL) and negative group (hs-TnT<0.014 ng/mL) . Then all patients were treated and followed up for 30 days. The sensitivity, specificity, positive predictive value and negative predictive value of adverse events of prognosis were calculated, and ROC curve was drawn to analyze the values in different grouping methods for the prognostic evaluation.Results Thirteen adverse events occurred in all patients. The single test showed that sensitivity, specificity, positive predictive value, and negative predictive value of hs-TnT for predicting adverse events were respectively 84.6%,55.2%,22%,and 96%. When sPESI was used alone, sensitivity, specificity, positive predictive value and negative predictive value were 92.3%, 48.8%, 21.1% , and 97.7% . Results of combined testing showed 100% sensitivity, 29% specificity, 17.6% positive predictive value, and 100% negative predictive value. The ROC curve area of the sPESI, hs-TnT, sPESI and hs-TnT are 0.832 (95% CI, 0.705-0.958), 0.825 (95%CI, 0.694-0.957),0.872 (95%CI, 0.773-0.971) . Conclusions PESI and hs-TnT have clinical value in evaluating the short-term prognosis of hemodynamically stable pulmonary embolism. sPESI combined with hs-TnT has higher significance, especially in patients with low-risk PE.

ABSTRACT

OBJECTIVE@#To better understand the pathological causes of bone loss in a space environment, including microgravity, ionizing radiation, and ultradian rhythms.@*METHODS@#Sprague Dawley (SD) rats were randomly divided into a baseline group, a control group, a hindlimb suspension group, a radiation group, a ultradian rhythms group and a combined-three-factor group. After four weeks of hindlimb suspension followed by X-ray exposure and/or ultradian rhythms, biomechanical properties, bone mineral density, histological analysis, microstructure parameters, and bone turnover markers were detected to evaluate bone loss in hindlimbs of rats.@*RESULTS@#Simulated microgravity or combined-three factors treatment led to a significant decrease in the biomechanical properties of bones, reduction in bone mineral density, and deterioration of trabecular parameters. Ionizing radiation exposure also showed adverse impact while ultradian rhythms had no significant effect on these outcomes. Decrease in the concentration of the turnover markers bone alkaline phosphatase (bALP), osteocalcin (OCN), and tartrate-resistant acid phosphatase-5b (TRAP-5b) in serum was in line with the changes in trabecular parameters.@*CONCLUSION@#Simulated microgravity is the main contributor of bone loss. Radiation also results in deleterious effects but ultradian rhythms has no significant effect. Combined-three factors treatment do not exacerbate bone loss when compared to simulated microgravity treatment alone.

ABSTRACT

Japanese encephalitis (JE) is a serious public health issue. This study was undertaken to better understand the relationship between JE distribution and environmental factors in China. JE data from 2005 to 2010 were retrieved from National Notifiable Disease Report System. ArcGIS, remote sensing techniques, and R software was used to exhibit and explore the relationship between JE distribution and environmental factors. Our results indicated that JE cases were mostly concentrated in warm-temperate, semitropical and tropical zones with annual precipitation > 400 mm; Broad-leaved evergreen forest, shrubs, paddy field, irrigated land, dryland, evergreen coniferous forest, and shrubland were risk factors for JE occurrence, and the former five were risk factors for counties with high JE incidence. These findings will inform the effective allocation of limited health resources such as intensive vaccination, surveillance and training in areas with high environmental risk factors.
