[Component Properties and Heavy Metal Accumulation Characteristics of Contaminated Rice Straw Biochar During Oxygen-controlled Pyrolysis].

Pyrolysis is an important technology to achieve the harmlessness and recycling of contaminated biomass. In this study, the effects of oxygen-controlled atmosphere on the component properties and heavy metal accumulation characteristics of contaminated rice straw biochar were studied. The results showed that low-oxygen pyrolysis could effectively produce biochar using contaminated rice straw and improve the stability of heavy metals in biochar.

Altered gut microbiota composition in children and their caregivers infected with the SARS-CoV-2 Omicron variant.

Background: Gut microbiota alterations have been implicated in the pathogenesis of coronavirus disease 2019 (COVID-19). This study aimed to explore gut microbiota changes in a prospective cohort of COVID-19 children and their asymptomatic caregivers infected with the severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) Omicron variant.

Methods: A total of 186 participants, including 59 COVID-19 children, 50 asymptomatic adult caregivers, 52 healthy children (HC), and 25 healthy adults (HA), were recruited between 15 April and 31 May 2022.

[Lactose intolerance in neonates with non-infectious diarrhea].

Objective: To investigate the development of lactose intolerance in neonates with non-infectious diarrhea and its association with diarrhea, and to evaluate the diagnostic values of fecal pH value and urine galactose determination for neonatal lactase deficiency.

Methods: Seventy hospitalized neonates who developed non-infectious diarrhea between October 2012 and June 2015 were enrolled as the diarrhea group, and 162 hospitalized neonates without non-infectious diarrhea were enrolled as the non-diarrhea group. Test paper was used to determine fecal pH value.

[Different expression of TNF-alpha in brain and peripheral organs after cerebral contusion of rats].

Objective: To compare the expression of tumor necrosis factor-alpha (TNF-alpha) between brain and peripheral organs after cerebral contusion in order to provide the scientific theoretical basis for forensic pathological diagnosis and wound age estimation.

Methods: Brain and peripheral organs including heart, liver, spleen, lung, kidney tissues of 45 SD rats after the cerebral contusion were obtained and TNF-alpha of these tissues were analyzed with immunohistochemistry methods.

Results: TNF-alpha was detected at 1 h in brain, reaching maximum at 6 h and 3 d after the cerebral contusion, and then decreased but still kept at high expression level at 7 d.

[Effect on PGF2alpha in plasma in primary dysmenorrhea treated with eye acupuncture].

Objective: To observe the clinical curative effect of primary dysmenorrhea and the content of prostaglandin F2alpha (PGF2alpha) in peripheral blood of menstrual periods treated with eye acupuncture therapy.

Methods: One hundred and ten cases of primary dysmenorrhea were randomly divided into an eye acupuncture group (60 cases) and a medication group (50 cases). In eye acupuncture group, low energizer area, liver area, kidney area, heart area and spleen area etc.

[Eye acupuncture for treatment of renal and ureteral colic].

Objective: To observe the therapeutic effect of eye acupuncture on renal and ureteral colic induced by ureterolith.

Methods: One hundred and eighty cases were randomly divided into an eye acupuncture group (n=90), a Morphine group (n=40) and a Bucinnazine group (n=50). The eye acupuncture group were treated with acupuncture at eye acupoints for killing pain, the Morphine group with intramuscular injection of Morphine and Atropine, and the Bucinnazine group with intramuscular injection of Bucinnazine and Atropine.
