Correlation between matrix metalloproteinase-2, matrix metalloproteinase-9, and tissue inhibitor of metalloproteinases-1 and white matter hyperintensities in patients with cerebral small vessel disease based on cranial magnetic resonance 3D imaging.

Objective: The objective of this study was to investigate the correlation between serum levels of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinases-1 (TIMP-1) levels and their ratios with the severity of white matter hyperintensities (WMHs) in patients with cerebral small vessel disease (CSVD).

Methods: This cross-sectional study was done on a prospective cohort of patients with CSVD. Qualitative and quantitative analyses of WMHs were performed using Fazekas grading and lesion prediction algorithm (LPA) methods.

Correlation between lipid-lowering therapy and cerebral microbleeds.

Objective: To investigate if there is a correlation between lipid-lowering treatment with statins and the occurrence, number, and location of cerebral microbleeds (CMBs) among patients with ischemic cerebrovascular disease (ICVD), and also to compare treatment with atorvastatin and rosuvastatin in terms of the occurrence of CMBs and their differences.

Methods: In this retrospective study, we included patients who were diagnosed with ICVD and underwent susceptibility weighted imaging (SWI) in a grade A tertiary hospital from October 1, 2014 to October 1, 2022. We collected information on previous statin use, past medical history, clinical test indicators, and imaging data.

A comprehensive health classification model based on support vector machine for proseal laryngeal mask and tracheal catheter assessment in herniorrhaphy.

In order to classify different types of health data collected in clinical practice of hernia surgery more effectively and improve the classification performance of support vector machine (SVM). A prospective randomized study was conducted. Sixty patients undergoing hernia repair under general anesthesia were randomly divided into two groups, PLMA group ( = 30) and ETT group ( = 30), for airway management.

[Identification of RhCcEe Mixed Visual Field in Patients with Regular Blood Transfusion and Efficacy Analysis of the Matched Transfusion].

Objective: To explore the feasibility of RhCcEe blood group antigen mixed visual field identification in patients with regular blood transfusion, to follow up and evaluate the efficacy of matched transfusion and its clinical significance.

Methods: RhCcEe genotyping for 142 patients with regular transfusion in our hospital was carried out by PCR-SSP method. According to the results of genotyping, 48 patients voluntarily selected the continuous transfusion of RhCcEe matched red blood cells, 46 patients received random blood transfusion (RhCcEe mismatched transfusion), 42 patients received partial RhCcEe matched transfusion (unable to provide fully matched RhCcEe donors each time), and 6 patients' blood transfusion data were lost.

Phytoremediation of Mn-contaminated paddy soil by two hyperaccumulators (Phytolacca americana and Polygonum hydropiper) aided with citric acid.

The purpose of this study was to investigate the phytoremediation potential of two hyperaccumulator plants, Phytolacca americana L. and Polygonum hydropiper L., on manganese-contaminated paddy soils.

[Stenting of subtotal conclusion of internal carotid artery and comparing the cerebral embolic load of proximal balloon protection device with distal filter protection device].

Objective: To study the safety, efficacy and perioperative complications of endovascular therapy in the treatment of subtotal conclusion of internal carotid artery(ICA) in patients. To compare the cerebral embolic load of proximal balloon protection device versus distal filter protection device during the operation.

Methods: Review all the operations of stenting for subtotal conclusion of ICA in Xuanwu hospital.

Inhibition activities of polysaccharide (RG4-1) from Gentiana rigescens against RSV.

Respiratory syncytial virus (RSV) is the most important cause of lower respiratory tract infection in infants and young children. With the emergence of drug-resistant strains of RSV, new antiviral agents are needed urgently. Gentiana rigescens is a kind of Chinese herb, belonging to Gentianaceae, which has long been used as a folk medicine for curing inflammation, bacterial infection, viral infection, and so on.

Concentration and potential health risk of heavy metals in market vegetables in Chongqing, China.

Concentration and daily intake (DI) of heavy metals (Pb, Zn, Mn, Cu, Cd and Cr) in market vegetables in Chongqing of China are investigated and their potential health risk for local consumers is simultaneously evaluated by calculating the target hazard quotient (THQ). The results showed that the measured Pb and Cd concentrations exceeded the safety limits given by FAO/WHO and Chinese regulations, indicating serious contamination of market vegetables by these metals. As respective DI values for Pb, Mn and Cd were also above the international guideline bases, health risk to the consumers is obvious.

[Effect of an active component from Forsythia suspensa (Thunb.) Vahl against respiratory syncytial virus in vitro].

Objective: To study the extraction of an active component LC-4 from Forsythia suspensa (Thunb.) Vahl and anti-respiratory syncytial virus (RSV) effect in vitro.

Methods: The extration from boiling water of Forsythia suspensa were extracted by hot water extraction and were precipitated by ethanol and were elicited by macroporous adsorptive resins column chromatography.

An improved embryonated chicken egg model for the evaluation of antiviral drugs against influenza A virus.

Influenza is a serious global public health problem and an economic burden. With the continual emergence of new influenza A virus strains, new antiviral drugs are needed urgently. In this study, an improved embryonated chicken egg model for evaluating antiviral activity against Influenza A virus was developed.

Copper and Zinc in a paddy field and their potential ecological impacts affected by wastewater from a lead/zinc mine, P. R. China.
