Targeting S100A9 attenuates social dysfunction by modulating neuroinflammation and myelination in a mouse model of autism.

Growing evidence supports a role for dysregulated neuroinflammation in autism. However, the underlying mechanisms of microglia-evoked neuroinflammation in the development of autistic phenotypes have not been elucidated. This study aimed to investigate the role and underlying mechanisms of microglial S100 calcium-binding protein A9 (S100A9) in autistic phenotypes.

Staged angioplasty in 2 patients with severe carotid artery stenosis: A case report and literature review.

Rationale: Cerebral infarction is a common ischemic cerebrovascular disease, associated with high rates of morbidity, disability, and recurrence, that can seriously affect patient physical and mental health, as well as quality of life. Carotid artery stenosis is an independent risk factor of cerebral infarction. Following rapid developments in interventional technology and materials science, carotid artery stenting has arisen an important treatment option for carotid artery stenosis.

Mesenchymal stem cell-derived extracellular vesicles in skin wound healing: roles, opportunities and challenges.

Skin wounds are characterized by injury to the skin due to trauma, tearing, cuts, or contusions. As such injuries are common to all human groups, they may at times represent a serious socioeconomic burden. Currently, increasing numbers of studies have focused on the role of mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in skin wound repair.

Exploration of the Risk Factors of Anemia in Patients with Tuberculous Meningitis in South China.

Objective: Central nervous system (CNS) infection has a high incidence and mortality worldwide. Tuberculous meningitis (TBM) accounts for approximately 5-6% of all extrapulmonary tuberculosis (TB), and is considered an extremely lethal form of CNS TB, which has become an important threat to human health. Anemia is a common symptom of TB, and its prevalence is generally higher in patients with TBM than in other meningitis patients and healthy individuals.

The protective effect of manganese superoxide dismutase from thermophilic bacterium HB27 on hydrochloric acid-induced chemical cystitis in rats.

Purpose: To evaluate the effects of manganese superoxide dismutase (Mn-SOD) from thermophilic bacterium HB27 (name as Tt-SOD) on chemical cystitis.

Methods: Control and experimental rats were infused by intravesical saline or hydrochloric acid (HCl) on the first day of the experiments. Saline, sodium hyaluronate (SH) or Tt-SOD were infused intravesically once a day for three consequent days.

[Efficacy of apolipoprotein 2-Jifusheng in the treatment of osteomyelitis in rabbits].

Objective: To evaluate the effect of one-stage treatment of bone morphogenetic protein 2 combined with Jifusheng in the experimental model of osteomyelitis in rabbits.

Methods: The model of chronic osteomyelitis of tibia was established in 30 3-month-old male New Zealand white rabbits with a body weight of (2.0±0.

Association between kidney stones and risk of developing stroke: a meta-analysis.

Background: Many studies have described the relationship between kidney stones and stroke, but the results are controversial, so we conducted this meta-analysis to estimate the relationship between kidney stones and the risk of developing stroke.

Methods: Studies were marked with a comprehensive search of PubMed, EMBASE, Google, and ISI Web of Science databases through 25 March 2020. Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted, and a random-effects model or fix-effects model was used to compute the pooled combined risk estimate.

Effect of glycated hemoglobin index and mean arterial pressure on acute ischemic stroke prognosis after intravenous thrombolysis with recombinant tissue plasminogen activator.

To determine whether glycated hemoglobin and mean arterial pressure (MAP) during thrombolysis are prognostic factors of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) for acute ischemic stroke (AIS).A total of 125 AIS patients, who received rt-PA intravenous thrombolysis in our hospital, were included into the present study, and divided into good prognosis group and poor prognosis group. Univariate and multivariate logistic regression analyses were used to determine the prognostic factors of AIS treated by rt-PA thrombolysis, Spearman correlation analysis was used to analyze the correlation of the accumulated cigarette consumption in the smoking subgroup and glycated hemoglobin in the diabetic subgroup with the prognosis after intravenous thrombolysis and the symptomatic intracranial hemorrhage (sICH).

Pathfast presepsin assay for early diagnosis of systemic inflammatory response syndrome in patients with nephrolithiasis.

It is relatively difficult to diagnose bacterial sepsis in nephrolithiasis patients. The aim of the study is to evaluate the diagnostic ability of presepsin in the differential diagnosis including SIRS, infection, or sepsis and to compare its diagnostic value with other markers, mainly as CRP, procalcitonin (PCT), and white blood cell (WBC) in patients of nephrolithiasis presenting with SIRS. 39 patients of nephrolithiasis who were diagnosed as SIRS were prospectively investigated.

Peroxidase-like activity of water-soluble cupric oxide nanoparticles and its analytical application for detection of hydrogen peroxide and glucose.

Water-soluble cupric oxide nanoparticles are fabricated via a quick-precipitation method and used as peroxidase mimetics for ultrasensitive detection of hydrogen peroxide and glucose. The water-soluble CuO nanoparticles show much higher catalytic activity than that of commercial CuO nanoparticles due to their higher affinity to hydrogen peroxide. In addition, the as-prepared CuO nanoparticles are stable over a wide range of pH and temperature.

[Analysis of fatal risk factors for severe acute pancreatitis: a report of 141 cases].

Objective: To investigate the risk factors affecting the mortality of severe acute pancreatitis (SAP).

Methods: The clinical data of 141 patients with SAP treated from January 2001 to October 2005 were analyzed retrospectively. All the patients were divided into 2 groups, the death group and the survival group.

[Study of effect and mechanism of c-myb on the fertilization in mouse].

Aim: To investigate the distribution of c-myb, an oncoprotein, in mouse oocytes-cumulus cell complex and sperm immunohistochemically.

Methods: To study the effect of c-myb on mouse fertilization in vitro, various concentration of c-myb antisense-oligodeoxynucleotides (c-myb ASODNs) were incubated with sperms and oocytes during fertilization. To explore the possible mechanism involved in fertilization, the relationship between c-myb ASODNs and GABA or dbcAMP or Verapamil or Progesterone in fertilization was also observed by immunohistochemical methods.

[Experimental study of c-erbB2 on the fertilization in mouse].

Aim And Methods: The distribution of ErbB2 in mouse testis, epididymidis, ovaries, oocyte-cumulus cells-complexes in oviducts and sperms was investigated immunohistochemically. To study the effect of c-erbB2 on mouse fertilization in vitro, various concentrations of c-erbB2 antisense oligonucleotides (c-erbB2 ASODNs) were incubated with sperms and oocyte-cumulus cells-complexes during fertilization in vitro. To explore possible mechanisms involved in fertilization, the relationship between c-erbB2 ASODNs and GABA, or dbcAMP, or verapamil during fertilization in vitro was also observed.

[Expression of c-fos in various functional state of rat ovaries].

Aim And Methods: The method of labeled streptavidin biotin was used to study the expression of c-fos in various functional state of rat ovaries and its relationship with the levels of serum estradiol and progesterone.

Results: (1) In the mature rat, c-fos expression was found higher in interstitial gland and stroma of proestrous ovaries and lower in estrous ovaries, and was found higher in luteal cells and stroma of pregnant ovaries and lower in diestrous ovaries. There was a positive correlation between the area and optical density of c-fos expression and the levels of serum E2 and P.
