Effects of enriched environment on the expression of ß-amyloid and transport-related proteins LRP1 and RAGE in chronic sleep-deprived mice.

Sleep plays an important role in the learning process and memory consolidation, and sleep deprivation (SD) leads to inadequate memory consolidation and plays an important role in brain development and plasticity. SD increases ß-amyloid levels while impairing cognitive function. We explored the effect of enriched environment (EE) on ß-amyloid and transporter protein LRP1 and receptor for advanced glycosylation end-products (RAGE) expression in chronic sleep deprived mice. We randomly divided mice into four groups (n = 10), the standard environment group (Ctrl group), the sleep deprivation group (SD group), the enriched environment intervention group (EE group), and the sleep deprivation plus environmental enrichment intervention group (SD + EE group). A modified multi-platform SD model was used to sleep deprive the mice for 19 h per day. Five hours of EE intervention was performed daily in the EE group and the SD + EE group, respectively. The behavioral measurements of mice were performed by Y-maze method and new object recognition; the expression levels of Aß1-42, LRP1, and RAGE in prefrontal cortex and hippocampus of mice were measured by immunofluorescence; the expression levels of LRP1 and RAGE in prefrontal cortex and hippocampus were detected by Western blot. The results showed that EE could effectively ameliorate the effects of SD on cognitive impairment, reduce SD induced Aß deposition, and decrease the expression of RAGE, while increase the expression of LRP1.

MicroRNA-221 and microRNA-222 regulate gastric carcinoma cell proliferation and radioresistance by targeting PTEN.

BACKGROUND: MicroRNAs (miRNAs) can function as either oncogenes or tumor suppressor genes via regulation of cell proliferation and/or apoptosis. MiR-221 and miR-222 were discovered to induce cell growth and cell cycle progression via direct targeting of p27 and p57 in various human malignancies. However, the roles of miR-221 and miR-222 have not been reported in human gastric cancer. In this study, we examined the impact of miR-221 and miR-222 on human gastric cancer cells, and identified target genes for miR-221 and miR-222 that might mediate their biology. METHODS: The human gastric cancer cell line SGC7901 was transfected with AS-miR-221/222 or transduced with pMSCV-miR-221/222 to knockdown or restore expression of miR-221 and miR-222, respectively. The effects of miR-221 and miR-222 were then assessed by cell viability, cell cycle analysis, apoptosis, transwell, and clonogenic assay. Potential target genes were identified by Western blot and luciferase reporter assay. RESULTS: Upregulation of miR-221 and miR-222 induced the malignant phenotype of SGC7901 cells, whereas knockdown of miR-221 and miR-222 reversed this phenotype via induction of PTEN expression. In addition, knockdonwn of miR-221 and miR-222 inhibited cell growth and invasion and increased the radiosensitivity of SGC7901 cells. Notably, the seed sequence of miR-221 and miR-222 matched the 3'UTR of PTEN, and introducing a PTEN cDNA without the 3'UTR into SGC7901 cells abrogated the miR-221 and miR-222-induced malignant phenotype. PTEN-3'UTR luciferase reporter assay confirmed PTEN as a direct target of miR-221 and miR-222. CONCLUSION: These results demonstrate that miR-221 and miR-222 regulate radiosensitivity, and cell growth and invasion of SGC7901 cells, possibly via direct modulation of PTEN expression. Our study suggests that inhibition of miR-221 and miR-222 might form a novel therapeutic strategy for human gastric cancer.

The Investigation and Analysis of the Situation of COVID-19 Vaccination and Vaccination Willingness in HIV/AIDS Population in Yunnan Province / 昆明医科大学学报

Objective To investigate the vaccination status and vaccination willingness of novel coronavirus in HIV/AIDS population in Yunnan.Methods From October 2021 to June 2022,a questionnaire survey was conducted among 2180 HIV/AIDS patients in Kunming,Qujing,Yuxi,Zhaotong,Puer,Baoshan,Lincang,Honghe,Wenshan,Xishuangbanna,Dali,Dehong and Nujiang prefectures.The questionnaire included age,sex,education,nationality,education level,vaccination,adverse reactions within 7 days after the vaccination,safety of COVID-19 vaccine,awareness of effectiveness,vaccination willingness and so on.Results Among the subjects,2109 completed 3 injections,accounting for 96.74%,and 71 were not vaccinated,accounting for 3.26% .Within 7 days of inoculation,local adverse reactions occurred in 116 cases,accounting for 5.50%,and systemic adverse reactions occurred in 56 cases,accounting for 2.66% .Injection site pain,fatigue and muscle pain accounted for the highest proportion of adverse symptoms in different sex,age and the Han nationality,while the proportion of minority adverse reactions was very low,and there was no difference among the different sex and age(P>0.05).The main reasons for the reluctance of HIV/AIDS population to be vaccinated were(recommended by doctors)that HIV/AIDS patients could not be vaccinated(67.61%)and may have serious adverse reactions after the vaccination(19.72%).The factors affecting the vaccination were found by logistic regression analysis,whether they were worried about infecting novel coronavirus(OR = 0.121,95% CI = 0.083～0.640,P<0.001)and how much they knew about COVID-19 vaccine(OR = 28.932,95% CI = 15.469～54.115,P<0.001),safety of vaccination(OR = 13.953,95% CI = 4.819～40.404,P<0.001)and belief in the preventive effect of vaccine(OR = 14.017,95% CI = 4.752～41.348,P<0.001)were significant factors affecting vaccination.Among the 13 prefectures and cities,Dehong(20),Zhaotong(21)and Lincang(14)had the largest number of unvaccinated people.Conclusion After the mass vaccination,the rate of adverse reaction in HIV/AIDS population is low,the symptoms are mild,the correct and scientific advice and guidance from doctors and the full understanding of the harmfulness of the disease,the safety,prevention and effectiveness of the vaccine are the key to complete vaccination and put an end to vaccine hesitancy.

Impact of low lethal concentrations of buprofezin on biological traits and expression profile of chitin synthase 1 gene (CHS1) in melon aphid, Aphis gossypii.

Buprofezin, a chitin synthesis inhibitor that can be used for the control of hemipteran pests, especially melon aphid, Aphis gossypii. The impact of low lethal concentrations of buprofezin on the biological parameters and expression profile of CHS1 gene were estimated for two successive generations of A. gossypii. The present result shows that the LC15 and LC30 of buprofezin significantly decreased the fecundity and longevity of both generations. Exposure of F0 individuals to both concentrations delay the developmental period in F1. Furthermore, the survival rate, intrinsic rate of increase (r), finite rate of increase (λ), and net reproductive rate (R0) were reduced significantly in progeny generation at both concentrations. However, the reduction in gross reproductive rate (GRR) was observed only at LC30. Although, the mean generation time (T) prolonged substantially at LC30. Additionally, expression of the CHS1 gene was significantly increased in F0 adults. Significant increase in the relative abundance of CHS1 mRNA transcript was also observed at the juvenile and adult stages of F1 generation following exposure to LC15 and LC30. Therefore, our results show that buprofezin could affect the biological traits by diminishing the chitin contents owing to the inhibition of chitin synthase activity in the succeeding generation of melon aphid.

AMP-activated protein kinase α1 serves a carcinogenic role via regulation of vascular endothelial growth factor expression in patients with non-small cell lung cancer.

AMP-activated protein kinase α1 (AMPK α1) is involved in the tumorigenesis of various cancer types. However, the role of AMPK α1 in non-small cell lung cancer (NSCLC) remains unclear. In the present study, 99 NSCLC tumor tissues and paired normal tissues were obtained. The expression levels of AMPK α1 were significantly upregulated in NSCLC tumor tissues compared with those in adjacent non-tumor lung tissues. The patients were further divided into two groups according to their expression levels of AMPK α1 in tumor tissues. The results outlined that overexpression of AMPK α1 was associated with poor prognosis. In addition, vascular endothelial growth factor (VEGF) expression levels were associated with malignant progression in patients with NSCLC. Patients with NSCLC that overexpressed AMPK α1 and VEGF had the worst outcomes. Moreover, AMPK α1 may positively regulate VEGF expression. These results suggest that AMPK α1 serves a carcinogenic role at least in part through the regulation of VEGF expression, and thus represents a potential treatment target in patients with NSCLC.

Objective To observe the value of augmented reality(AR)navigation system for assisting CT-guided puncture of pulmonary nodules in dog models.Methods Five healthy dogs were selected,and 4 target lung rings were implanted in each dog to build pulmonary nodule models.Deferring to crossover design,CT-guided punctures were performed with or without AR navigation 2 and 4 weeks after successful modeling,respectively,while punctures with AR navigation were regarded as AR group and the others as conventional group,respectively.The time duration of puncturing,the times of CT scanning,of needle adjustment,and the deviation distance between needle pinpoint to the center of pulmonary nodule shown on three-dimensional reconstruction were compared between groups.Results The duration time of puncture in AR group and conventional group was(13.62±5.11)min and(20.16±4.76)min,respectively.In AR group,the times of CT scanning,of needle adjustment,and the deviation distance was 2.40±0.50,2.75±0.44 and(2.94±1.92)mm,respectively,while in conventional group was 3.10±0.64,3.70±0.57 and(4.90±3.38)mm,respectively.The introduction of AR navigation was helpful to shortening the duration of puncture,reducing times of CT scanning and needle adjustment,also decreasing positioning error of needle pinpoint(all P＜0.05).In contrast,the variance of puncture sequences and dogs had no obvious effect on the results(both P＞0.05).Conclusion AR navigation system could improve accuracy and efficiency in CT-guided puncture of pulmonary nodules in dog models.

Correlation between Combined Urinary Metal Exposure and Grip Strength under Three Statistical Models: A Cross-sectional Study in Rural Guangxi / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to investigate the potential relationship between urinary metals copper (Cu), arsenic (As), strontium (Sr), barium (Ba), iron (Fe), lead (Pb) and manganese (Mn) and grip strength.@*METHODS@#We used linear regression models, quantile g-computation and Bayesian kernel machine regression (BKMR) to assess the relationship between metals and grip strength.@*RESULTS@#In the multimetal linear regression, Cu (β = -2.119), As (β = -1.318), Sr (β = -2.480), Ba (β = 0.781), Fe (β = 1.130) and Mn (β = -0.404) were significantly correlated with grip strength ( P < 0.05). The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was -1.007 (95% confidence interval: -1.362, -0.652; P < 0.001) when each quartile of the mixture of the seven metals was increased. Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength, with Cu, As and Sr being negatively associated with grip strength levels. In the total population, potential interactions were observed between As and Mn and between Cu and Mn ( P interactions of 0.003 and 0.018, respectively).@*CONCLUSION@#In summary, this study suggests that combined exposure to metal mixtures is negatively associated with grip strength. Cu, Sr and As were negatively correlated with grip strength levels, and there were potential interactions between As and Mn and between Cu and Mn.

AIM: To investigate the effect of 3-bro-mopyruvate cholesterol ester (3-BP-Cl) on the sensitivity of breast cancer to tamoxifen (TAM). METHODS: MTT assay and Calcein AM/PI staining were used to detect the effect of drugs on the viability of breast cancer cells. Kim's formula was used to detect synergistic anti-breast cancer effect of cholesterol 3-bromopyruvate and tamoxifen. The inhibitory effect of drugs on proliferation of breast cancer cells was detected by colony-forming assay. Flow cytometry was used to detect the apoptosis of breast cancer cells. Western blot assay was used to detect the expression of hexokinase 2, Bcl-2 and Bax proteins. RESULTS: MTT results showed that combination 3-BP-Cl and TAM could significantly inhibit the activity of MCF-7 cells (P1.15). Calcein AM / PI staining showed that the number of dead cells was the highest in the combination group. Colony-forming assay showed that the combination group had stronger inhibitory effect on the proliferation of MCF-7 cells than that of single drug groups. AnnexinV flow cytometry results showed that, the cell apoptosis in the combination group was significantly increased (P<0.01). Western blot results showed that 3-BP-Cl inhibited the expressions of hexoktokinase 2 and Bcl-2, and enhanced the expression of Bax in MCF-7 cells. CONCLUSION: 3-BP-Cl could increase the sensitivity of breast cancer cells to tamoxifen, and synergically inhibit the proliferation of breast cancer cells. The mechanism is possibly related to its effects of inhibiting the expression of HK2/Bcl-2, and enhancing the expression of Bax.

Research progress in quality control of Bufonis Venenum in preparations / 中国中药杂志

Bufonis Venenum, an animal medicinal material, is widely used for treating cardiovascular diseases and pain induced by rheumatics or malignant tumors. In view of the high activity and high toxicity, it is of great significance to pay attention to the quality control of Bufonis Venenum to ensure the safety and effectiveness of its preparations. China's drug standards involve 102 preparations(474 batch numbers) containing Bufonis Venenum approved for sale, including 14 preparations in the Chinese Pharmacopoeia(2020 edition) and 68 preparations in the standards issued by the Ministry of Health Drug Standard of the People's Republic of China. Bufonis Venenum is mostly used in pill and powder preparations in the form of raw powder, with the main functions of clearing heat, removing toxin, relieving swelling and pain, replenishing qi, activating blood, opening orifice, and awakening brain. Except the high level of quality control for Bufonis Venenum in the preparations in the Chinese Pharmacopoeia(2020 edition), the quality control standards of Bufonis Venenum in other preparations are low or even absent. Therefore, it is urgent to conduct research on the improvement of quality standards for the preparations containing Bufonis Venenum. This study retrieved the reports focusing on the quality evaluation and quality control of the preparations containing Bufonis Venenum from CNKI, PubMed, and Web of Science. Qualitative and quantitative analysis methods for 64 preparations containing Bufonis Venenum have been reported, mainly including thin-layer chromatography, HPLC fingerprint, and multi-component content determination. The index components mainly involved bufadienolides, such as gamabufalin, arenobufagin, bufotalin, bufalin, cinobufagin, and resibufogenin. According to the literature information, this paper suggests that attention should be paid to the correlations between the analysis methods and detection indexes of medicinal materials, decoction pieces and preparations, the monitoring of indole alkaloids, and the content uniformity inspection for further improving the quality standards for the preparations containing Bufonis Venenum.

Application of exosomes in brain-targeted delivery / 药学学报

Brain-targeted delivery plays an important role in the diagnosis and treatment of neurological diseases, but the existence of blood brain barrier (BBB) limits the development of brain-targeted delivery. As cell-derived nanovesicles, exosomes can participate in the transportation of substances between cells to mediate the communication between cells to play a biological regulatory role in vivo. Due to the low immunogenicity, low toxicity, high engineering and natural crossing over BBB, exosomes play an important role in brain-targeted delivery. In this paper, the composition of exosomes, the mechanism of brain targeted delivery and its role in various brain diseases are systematically described.

Association between genetic predisposition to childhood obesity and the risk of adult ischemic heart disease in China / 中华流行病学杂志

Objective: To examine the associations of childhood obesity, assessed by genetic variations of childhood body mass index (BMI), with the risk of adult ischemic heart disease (IHD) and major coronary event (MCE). Methods: More than 69 000 participants from the China Kadoorie Biobank were genotyped. After excluding those with coronary heart disease, stroke, or cancer at baseline, a total of 64 454 participants were included in this study. Based on genome-wide significant single nucleotide polymorphisms (SNPs), childhood BMI genetic risk score were constructed for every participant and divided into quintiles, with the lowest quintile as the low genetic risk group and the highest quintile as the high genetic risk group. Cox proportional hazards regression models were used to estimate the association between genetic predisposition to childhood obesity and the risk of ischemic heart disease. Results: During a median of 10.7 years of follow-up, 7 073 incident cases of IHD and 1 845 cases of MCE were documented. After adjusting for sex, age, region, and the first ten genetic principal components, the HRs (95%CIs) for IHD and MCE in the high genetic risk group were 1.10 (1.02-1.18) and 1.10 (0.95-1.27), compared with the low genetic risk group. IHD risk increased by 4% (2%-6%) for each one standard deviation increase in genetic risk score (trend P=0.001). After further adjustment for baseline BMI, the differences between genetic risk groups were not statistically significant, but there was still a linear trend between genetic risk score and IHD risk (trend P=0.019). Conclusions: IHD risk increased with genetic predisposition to childhood obesity, suggesting that childhood obesity is an important risk factor for the development of IHD in China. As an easily identifiable feature, changes of childhood BMI should be monitored regularly to realize early intervention of IHD in adults.

ObjectiveTo retrospectively analyze the clinical data of 52 patients with coronavirus disease-2019 （COVID-19） and explore the clinical efficacy of modified Sanxiaoyin on mild/moderate COVID-19 patients. MethodThe propensity score matching method was used to collect the clinical data of mild or moderate COVID-19 patients enrolled in the designated hospital of the Second Hospital of Jingzhou from December 2019 to May 2020. A total of 26 eligible patients who were treated with modified Sanxiaoyin were included in the observation group， and the 26 patients treated with conventional method were the regarded as the control. The disappearance of clinical symptoms， disappearance time of main symptoms， efficacy on traditional Chinese medicine （TCM） symptoms， hospitalization duration， laboratory test indicators， and CT imaging changes in the two groups were compared. ResultThe general data in the two groups were insignificantly different and thus they were comparable. After 7 days of treatment， the disappearance rate of fever， cough， fatigue， dry throat， anorexia， poor mental state， and poor sleep quality in the observation group was higher than that in the control group （P<0.05）， and the difference in the disappearance rate of expectoration and chest distress was insignificant. For the cases with the disappearance of symptoms， the main symptoms （fever， cough， fatigue， dry throat， anorexia， chest distress） disappeared earlier in the observation group than in the control group （P<0.01）. After 7 days of treatment， the scores of the TCM symptom scale of both groups decreased （P<0.01）， and the decrease of the observation group was larger that of the control group （P<0.01）. All patients in the two groups were cured and discharged. The average hospitalization duration in the observation group ［（12.79±2.68） d］ was shorter than that in the control group ［（15.27±3.11） d］ （P<0.01）. The effective rate in the observation group （92.31%， 24/26） was higher than that in the control group （76.92%， 20/26） . After 7 days of treatment， the lymphocyte （LYM） count increased （P<0.05）， and white blood cell （WBC） count and neutrophil （NEUT） count decreased insignificantly in the two groups. Moreover， levels of C-reactive protein （CRP）， erythrocyte sedimentation rate （ESR）， and procalcitonin （PCT） reduced in the two groups after treatment （P<0.01） and the reduction in the observation group was larger than that in the control group （P<0.01）. Through 7 days of treatment， the total effective rate on pulmonary shadow in the observation group （90.00%， 18/20） was higher than that in the control group （77.27%， 17/22） （P>0.05） and the improvement of lung shadow in the observation group was better than that in the control group （P<0.01）. ConclusionModified Sanxiaoyin can significantly alleviate fever， cough， fatigue， anorexia， chest distress， poor sleep quality， and other symptoms of patients with mild or moderate COVID-19， improve biochemical indicators， and promote the recovery of lung function. This paper provides clinical evidence for the application of modified Sanxiaoyin in the treatment of mild or moderate COVID-19.
