SMAD2/3 Phosphorylation Is Downregulated in T Cells in HIV-Infected Patients.

Persistent inflammation contributes to the exhaustion of immune system and non-AIDS-defining events in HIV-infected patients. Transforming growth factor β (TGF-β) is generally considered an anti-inflammatory cytokine. It is unclear that why high-level TGF-β coexists with chronic inflammation during HIV infection.

Nursing Skill Assessment of Hospital Nurses in Management of Critically Ill Patients.

Objective: To analyze the application of standardized nursing procedures in critically ill patients' nursing evaluation.

Methods: 90 cases of critically ill patients aged from 18 to 65 who were treated in our hospital from April 2020 to April 2021 were selected and divided into the control group and observation group, respectively, with 45 cases according to the drawing method. The rescue time, blood pressure, heart rate before and after nursing, adverse mood, length of stay, incidence of adverse events, ICU transfer and death, and satisfaction of 2 groups were statistically analyzed and compared.

Transarterial Onyx Embolization for Patients with Cavernous Sinus Dural Arteriovenous Fistulas Who Have Failed Transvenous Embolization.

Transvenous embolization is the treatment of choice for cavernous sinus dural arteriovenous fistulas (csDAVFs) despite occasional difficulty in transvenous catheterization. We reported our experience in the treatment of csDAVFs by transarterial Onyx embolization in patients who had failed transvenous catheterization. We reviewed the clinical and radiographic records of csDAVFs patients receiving transarterial Onyx embolization after failed transvenous Onyx embolization at our institution over a period of 31 months.

The length of an internal poly(A) tract of hibiscus latent Singapore virus is crucial for its replication.

Hibiscus latent Singapore virus (HLSV) mutants were constructed to study roles of its internal poly(A) tract (IPAT) in viral replication and coat protein (CP) expression. Shortening of the IPAT resulted in reduced HLSV RNA accumulation and its minimal length required for HLSV CP expression in plants was 24 nt. Disruption of a putative long range RNA-RNA interacting structure between 5' and 3' untranslated regions of HLSV-22A and -24A resulted in reduced viral RNA and undetectable CP accumulation in inoculated leaves.

Antioxidant and antiinflammation capacities of some pear cultivars.

Unlabelled: Five commercial pear cultivars were investigated for total phenolics and flavonoids contents, the main phenolic compounds, and their antioxidant and antiinflammation capacities. Four in vitro oxidant and 2 in vivo antiinflammation models were used to evaluate the pharmacological activities of the different pears. The main phenolic compounds were determined by high-performance liquid chromatography with diode-array detector, which result indicated that gallic acid ranged from 5.

Evaluation of the in vivo anti-inflammatory effects of extracts from Pyrus bretschneideri Rehd.

Pyrus bretschneideri Rehd., as a pharmaceutical supplement, is widely used in northern China to treat respiratory diseases. Our previous studies showed the ethanol extract of P.

Removal of nitrogen, phosphorus, and organic pollutants from water using seeding type immobilized microorganisms.

Objective: To study the possibility of removing nitrogen, phosphorus, and organic pollutants using seeding type immobilized microorganisms.

Methods: Lakes P and M in Wuhan were chosen as the objects to study the removal of nitrogen, phosphorus, and organic pollutants with the seeding type immobilized microorganisms. Correlations between the quantity of heterotrophic bacteria and the total nitrogen (TN), total phosphorus (TP), and total organic carbon (TOC) in the two lakes were studied.

Radical microsurgical treatment of intramedullary spinal cord tumors.

Background: The surgical treatment of intramedullary spinal cord tumor aims at complete removal and minimal postoperative deficit. This study was undertaken to evaluate the microsurgical features of intramedullary spinal cord tumors and the time for surgery and prognosis.

Methods: Twenty-one patients with intramedullary spinal cord tumor who had been treated at Nanfang Hospital, Guangzhou, China since 2000 were studied retrospectively.

Preparation of seeding type immobilized microorganisms and their degradation characteristics on Di-n-butyl phthalate.

Objective: To study the preparation of seeding type immobilized microorganisms and their degradation characteristics on di-n-butyl phthalate (DBP).

Methods: Diatomite, clinoptilolite, silk zeolite, and coal fly ash were chosen as reserved materials and modified. Their adsorption capacity and intensity in the bacteria were determined and the best carrier was picked out.

[A correlative study on heterotrophic bacteria and the main pollutant in city lakes' water].

Objective: To provide scientific basis for bioremediation of city lake, the distribution of heterotrophic bacteria and its correlation with major pollutions condition were studied.

Methods: Puping Lake and Moshui Lake of Wu Han City were choosen as the objects of our study. COD(cr) TOC, TP and TN were determined in sampled freshwater and sediment via the standard methods.

[A study on the model of tuberculous pleurisy and intrapleural inflammatory and immunological responses in rats].

Objective: To develop a rat model of tuberculous pleurisy and to explore the mechanism of intrapleural inflammatory and immunological responses.

Methods: Fifty Wistar rats were injected intrapleurally with 0.03 mg of standard human mycobacterium tuberculous bacilli H37Rv each.

[Radiation-induced rat cerebral neuron apoptosis].

Objective: To explore the correlation between X-ray-induced rat cerebral neuron apoptosis and radiation doses.

Methods: In a controlled experiment, the rats in the experimental group received X-ray radiation at different doses (2, 4, 6 and 8 Gy), and the apoptotic cerebral neurons were counted after in situ end-labeling and immunohistochemical staining.

Results: X-ray radiation induced apoptosis of rat cerebral neurons, and the apoptotic rate varied with the radiation doses.
