Deoxynivalenol induces apoptosis in PC12 cells via the mitochondrial pathway

Deoxynivalenol (DON) has broad toxicity in animals and humans. In this study the impact of DON treatment on apoptotic pathways in PC12 cells was determined. The effects of DON were evaluated on (i) typical indicators of apoptosis, including cellular morphology, cell activity, lactate dehydrogenase (LDH) release, and apoptosis ratio in PC12 cells, and on (ii) the expression of key genes and proteins related to apoptosis, including Bcl-2, Bax, Bid, cytochrome C (Cyt C), apoptosis inducing factor (AIF), cleaved-Caspase9, and cleaved-Caspase3. DON treatment inhibited proliferation of PC12 cells, induced significant morphological changes and apoptosis, promoted the release of Cyt C and AIF from the mitochondria, and increased the activities of cleaved-Caspase9 and cleaved-Caspase3. Bcl-2 expression decreased with increasing DON concentrations, in contrast to Bax and Bid, which were increased with increasing DON concentration. These data demonstrate that DON induces apoptosis in PC12 cells through the mitochondrial apoptosis pathway.

In situ growth of ZIF-67 on a nickel foam as a three-dimensional heterogeneous catalyst for peroxymonosulfate activation

Advanced oxidation processes based on sulfate radicals have been widely used to eliminate contaminants. In this study, an efficient cobalt-based three-dimensional heterogeneous catalyst was fabricated through in situ growth of ZIF-67 on nickel foam (NF/ZIF-67). The factors influencing NF/ZIF-67-activated peroxymonosulfate (PMS) were investigated. Enhanced RhB degradation was observed using NF/ZIF-67-activated PMS under neutral conditions and high temperatures. Sulfate radicals were the dominant active species for the oxidative decolorization of RhB with NF/ZIF-67-activated PMS. NF/ZIF-67 was easily separated from the solution, and it also retained high catalytic stability. This study provides a rapid and mild method for the fabrication of promising three-dimensional heterogeneous catalysts for PMS activation and wastewater treatment.

目的探讨西格列汀与阿卡波糖对初发2型糖尿病的治疗效果及胃肠道相关激素的影响。方法选取该院2012年5月—2013年12月收治的58例初发2型糖尿病患者为研究对象,随机将其分为两组,各29例,A组患者给予西格列汀治疗,B组患者给予阿卡波糖治疗,对两组患者血糖控制情况（空腹血糖、餐后2 h血糖及糖化血红蛋白）及胃肠道相关激素（胃饥饿素及胃泌素）变化进行比较。结果治疗后两组间血糖、血脂及体重质量指数变化比较,差异无统计学意义（P〉0.05）。A组患者治疗后空腹、餐后2 h胃饥饿素及胃泌素较治疗前明显下降,差异有统计学意义（P〈0.05）,B组患者上述指标则无显著变化,差异无统计学意义（P〉0.05）。结论西格列汀与阿卡波糖治疗初发2型糖尿病疗效均良好,但西格列汀可显著降低患者空腹及餐后胃饥饿素,更安全。     

3- to 24-month Follow-up on COVID-19 with Pulmonary Tuberculosis Survivors after Discharge: Results from a Prospective,Multicenter Study

ObjectiveCoronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors.MethodsFrom January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13 hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge.ResultsThirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9%) were men. Among them, nearly two-thirds (62.5%) of the survivors were moderate, three (9.4%) were severe, and more than half (59.4%) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6% at 3 months to 15.8% at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1%) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period.ConclusionThe proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

乙型肝炎病毒DNA定量检测对乙型肝炎产妇母乳喂养的临床指导价值

目的探讨乙型肝炎（乙肝）病毒DNA（HBV—DNA）定量检测对乙肝产妇母乳喂养的临床指导价值。方法选择2012年1～lO月检测乙肝表面抗原（HBsAg）阳性（＋）的产妇100例设为研究组,其中大三阳组产妇32例,小三阳组产妇41例,HBsAg（＋）,乙肝核心抗体（＋）组产妇27例。选择同期健康产妇100例设为对照组,分别检测各组产妇血清及乳汁中HBV—DNA水平情况,并对结果进行综合分析。结果研究组3个小组产妇血清和乳汁HBV—DNA阳性率均在85．0％以上,明显高于对照组的0．0％,差异均有统计学意义（P〈0．05）;研究组各组产妇血清和乳汁HBV—DNA水平分别两两比较,差异均有统计学意义（P〈0．05）;研究组产妇乳汁HBV—DNA水平与血清HBV—DNA水平呈正相关f相关系数（r）=0．9569,P〈0．05]。结论乙肝产妇产后能否实施母乳喂养与产后产妇血清及初乳中HBV—DNA的水平有关,因此,必须依据检测结果决定喂养方式．以保证婴儿的哺乳安全。
