Integrase inhibitors (INSTIs) are the newest class of antiretroviral drug which are available to people living with the human immunodeficiency virus (HIV). Since 2007, five types of INSTIs have been marketed: Raltegravir, Elvitegravir, Dolutegravir, Bictegravir and Cabotegravir, all of which were approved by the US Food and Drug Administration (FDA) for use in the initiation of antiretroviral therapy (ART) in treatment-na?ve individuals. Compared with other types of antiretroviral drugs, INSTIs have better efficacy and tolerability, so many countries around the world have listed INSTIs-containing regimens as the preferred regimen for HIV ART. In recent years, with the widespread use of INSTIs, some research data suggest that INSTIs may have some adverse effects (AEs), such as central nervous system symptoms, abnormal lipid metabolism, weight gain, abnormal liver and kidney function, etc. This review summarizes the current use of INSTIs in people living with the HIV, and highlights the clinical efficacy and their AEs among the five types of INSTIs in China.

Inertial microfluidics,as a microfluidic technology with the ability to precisely manipulate particles and cells with high throughput,has attracted widespread attention.However,challenges remain in achieving particle focusing with insensitivity to flow rates in large-scale channels,mainly due to the instability of secondary flows within the inertial microfluidic chip.This study developed a microstructure-assisted ultra-low aspect ratio spiral microchannel,which utilized the stability and acceleration of secondary flows to achieve inertial particle focusing.The research results demonstrated successful particle focusing within a 1 mm-wide spiral channel chip,for different diameter sizes(7.3 μm and 15.5 μm),within a wide range of flow rates(0.5-3 mL/min).The focusing efficiencies for these particles were measured to be above 94%and 99%,respectively.Additionally,it was observed that the particle focusing position was approximately 100 μm away from the channel walls,significantly larger than other inertial focusing chips.Consequently,by incorporating ordered microstructures within the spiral channel chip,the stability and enhancement of secondary flows were achieved,resulting in flow rate and particle size-insensitive inertial focusing.Compared to traditional methods of inertial focusing,this design had advantages of not requiring additional sheath flow operations,and boasted high throughput and ease of manufacturing.This innovative structure opened up vast prospects for the development of portable inertial microfluidic chips,and could be used in the fields such as cell analysis and detection,flow cytometry,and online sample processing.

ObjectiveTo evaluate the lipid-lowering activity of Quansanqi tablets(QSQ), an innovative new drug of Panax notoginseng. MethodMice and golden hamsters were used to establish a hyperlipidemia model by injecting egg yolk milk and feeding high-fat diets. The levels of total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were detected, and liver function indicators [alanine aminotransferase (ALT), aspartate amino-transferase (AST), and alkaline phosphatase (ALP)] of golden hamsters were detected. Hematoxylin-eosin (HE) staining was used to observe the degree of liver injury. In the experiments, a normal group, a model group, an atorvastatin calcium group, and low-, medium-, and high-dose QSQ groups (0.32, 0.64, 1.28 g·kg-1 for mice, and 0.16, 0.32, 0.64 g·kg-1 for golden hamsters) were set up. ResultCompared with the normal group, the acute hyperlipidemia model mice showed increased TC, TG, and LDL-C levels (P<0.01), and the hyperlipidemia model mice showed increased TC and LDL-C levels (P<0.01). Additionally, the hyperlipidemia model golden hamsters showed increased serum TC, TG, LDL-C, ALT, AST, and ALP levels (P<0.05, P<0.01). HE staining indicated the presence of fat accumulation in the liver, accompanied by inflammatory reactions. Compared with the model group, QSQ of various doses could reduce TC, TG, and LDL-C levels in acute hyperlipidemia model mice (P<0.05, P<0.01), and the high-dose QSQ could reduce TC and LDL-C levels (P<0.01) and increase HDL-C level (P<0.05) in hyperlipidemia model mice, as well as reduce TC, TG, and LDL-C levels in hyperlipidemia model golden hamsters (P<0.05, P<0.01), especially in the first two weeks. In addition, atorvastatin calcium could further increase ALT, AST, and ALP levels (P<0.05, P<0.01) and aggravate liver function damage, while low-dose QSQ could reduce ALT, AST, and ALP (P<0.05), and medium- and high-dose QSQ did not cause further liver function damage. ConclusionQSQ have a significant lipid-lowering effect on different hyperlipidemia model animals and can improve liver function and liver injury.

Objective: To identify the main metals involved in cognitive impairment in the Chinese oldest old, and explore the association between these metal exposures and cognitive impairment. Methods: A cross-sectional study was conducted on 1 568 participants aged 80 years and older from Healthy Aging and Biomarkers Cohort Study (2017 to 2018). Fasting venous blood was collected to measure the levels of nine metals (selenium, lead, cadmium, arsenic, antimony, chromium, manganese, mercury, and nickel). The cognitive function of these participants was evaluated by using the Chinese version of the Mini-Mental State Examination (CMMSE). The random forest (RF) was applied to independently identify the main metals that affected cognitive impairment. The multivariate logistic regression model and restricted cubic splines (RCS) model were used to further verify the association of the main metals with cognitive impairment. Results: The age of 1 568 study subjects was (91.8±7.6) years old, including 912 females (58.2%) and 465 individuals (29.7%) with cognitive function impairment. Based on the RF model (the out-of-bag error rate was 22.9%), the importance ranking of variables was conducted and the feature screening of five times ten-fold cross-validation was carried out. It was found that selenium was the metal that affected cognitive function impairment, and the other eight metals were not included in the model. After adjusting for covariates, the multivariate logistic regression model showed that with every increase of 10 μg/L of blood selenium levels, the risk of cognitive impairment decreased (OR=0.921, 95%CI: 0.889-0.954). Compared with the lowest quartile(Q1) of blood selenium, the ORs (95%CI) of Q3 and Q4 blood selenium were 0.452 (0.304-0.669) and 0.419 (0.281-0.622) respectively. The RCS showed a linear dose-response relationship between blood selenium and cognitive impairment (Pnonlinear>0.05). Conclusion: Blood selenium is negatively associated with cognitive impairment in the Chinese oldest old.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
