    Abstract Bacteria develop a variety of extracellular fibrous structures crucial for their survival, such as flagella and pili. In this study, we use cryo-EM to identify protein fibrils surrounding lab-cultured Bacillus amyloiquefaciens and discover an unreported fibril species in addition to the flagellar fibrils. These previously unknown fibrils are composed of Vpr, an extracellular serine peptidase. We find that Vpr assembles into fibrils in an enzymatically active form, potentially representing a strategy of enriching Vpr activities around bacterial cells. Vpr fibrils are also observed under other culture conditions and around other Bacillus bacteria, such as Bacillus subtilis, which may suggest a general mechanism across all Bacillus bacterial groups. Taken together, our study reveals fibrils outside the bacterial cell and sheds light on the physiological role of these extracellular fibrils.

    Abstract Rationale: HELLP syndrome, a rare but serious obstetric complication, is often overdiagnosed due to its nonspecific symptoms and inappropriate clinical testing.
    Patient concerns: A 30-year-old nulliparous pregnant Chinese woman at gestational age of 28+1 weeks was admitted to our hospital because Doppler ultrasonography at a local hospital had detected loss of fetal umbilical artery end-diastolic blood flow lasting 12 hours. On admission to our hospital, the patient showed elevated blood pressure (148/84 mm Hg), but blood pressure and laboratory indicators after admission were normal. However, the patient developed abdominal pain during hospitalization.
    Interventions: Dexamethasone was given after admission to our hospital to promote fetal lung maturation, magnesium sulfate was given to protect fetal brain nerves, and maternal blood pressure was closely monitored. In addition, fetal umbilical artery blood flow was dynamically monitored. After three days in hospital with normal blood pressure, the patient developed abdominal pain accompanied by diarrhea. She was positive for Murphy's sign and laboratory tests showed no obvious abnormalities. Acute cholecystitis was suspected, but symptomatic and supportive treatment did not relieve abdominal pain and her blood pressure increased progressively to 212/130 mm Hg. Magnesium sulfate was given immediately to prevent spasm, and nitroglycerin was administered intravenously against hypertension. Liver enzymes, blood coagulation, and routine urinalysis were abnormal. The patient was diagnosed with HELLP syndrome, and an emergency cesarean section was performed.
    Diagnosis: HELLP syndrome.
    Outcomes: After the cesarean section, platelet (PLT) count continuously decreased and transaminase and bilirubin levels continously increased. The newborn was transferred to the neonatal intensive care unit after birth and discharged at a corrected gestational age of 34 weeks. By postoperative day 6, laboratory indicators had returned to normal and the patient was discharged.
    Lessons subsections: Our case highlights that HELLP syndrome is a serious complication, and it should be diagnosed carefully and not arbitrarily on the basis of some abnormal indicators and stable clinical manifestations. Accurate early identification, active monitoring and management are essential for improving prognosis and avoiding maternal or infant mortality.

    Abstract Partial nitrification is an effective process for treating high-strength ammonium landfill leachate with low C/N ratio, for the cooperation with denitrification can save almost 40% carbon addition in biological nitrogen removal. However, high ammonia loading often causes the instability of partial nitrification process. Less carbon addition can promote the stability of partial nitrification and increase the nitrite accumulation ratio (NAR). Nevertheless, the microbial mechanisms within remain further elusive. In this study, two laboratory-scale sequencing batch reactors were constructed and operated for 125 days, which were fed with ammonia synthetic wastewater with C/N of 0.6 (CN system) and C/N of 0.0 as the control (N system). CN system performed more stably and had the highest NAR of 100%. Extracellular polymeric substances (EPS) generated from carbon source provided spatial and nutrient niches to tighten the cooperation of functional microorganisms, thus, enhanced the stability and efficiency of partial nitrification. Thauera was the dominant denitrifier in CN system. Nitrosomonas was one of the most important autotrophic ammonia oxidizing bacteria, while Paracoccus and Flavobacterium were the main heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria in CN system. The enrichment of HN-AD bacteria outcompeted nitrite oxidizing bacteria (NOB), therefore leaded to higher nitrite accumulation in CN system. The findings of this study may be conducive to increasing the understanding of the microbial collaboration mechanisms of partial nitrification, thereby provides theoretical support for the improvement of biological nitrogen removal technology.

    Abstract Backgroud: Toll-like receptor 4 (TLR4), a key mediator of inflammatory responses, which is associated with vascular remodeling. The association between TLR4 and NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome in the regulation of vascular smooth muscle cell (VSMC) proliferation remains unclear. This study was to explore the role and underlying mechanisms of TLR4 in the proliferation of VSMC in hypertension.
    Methods: VSMC proliferation after TLR4 overexpression or downregulation was determined by CCK-8, EdU Incorporation and colony formation assays. Western blots were carried out to investigate the expression of TLR4 and NLRP3 inflammasome components in VSMCs. Next, blood pressure measurements and Hematoxylin and Eosin (HE) staining assays were performed in spontaneously hypertensive rats (SHR). Media thickness (M) and diameter lumen (L) were measured as indicators of vascular remodeling. The expression of TLR4, PCNA and NLRP3 inflammasome complex was analyzed by Western blots in the aorta of SHR.
    Results: We showed that TLR4 overexpression with cDNA enhanced, while knockdown of TLR4 with shRNA inhibited Ang II-induced VSMC proliferation. Besides, TLR4 overexpression upregulated the proteion expression of the NLRP3 inflammasome components including NLRP3, ASC and caspase-1, whereas their corresponding levels of expression were observed to decrease in TLR4 shRNA-transfected VSMCs. Knockdown of TLR4 attenuated vascular remodeling, blood pressure (BP) and the levels of NLRP3, ASC, caspase-1, IL-1β and IL-18 in SHR aortas.
    Conclusion: This study revealed that TLR4 regulated Ang II-induced VSMC proliferation through modulating the NLRP3 inflammasome. Knockdown of TLR4 attenuated the BP and vascular remodeling by inhibiting the expression of the NLRP3 inflammasome component in SHR. Our results support that TLR4 regulates VSMC proliferation in hypertension via triggering the NLRP3 inflammasome.

    Abstract To explore the effect of individualized comfortable nursing on prognosis of vacuum sealing drainage (VSD) in patients with orthopedic trauma. 110 patients with orthopedic trauma VSD were randomly divided into the control group and the observation group, with 55 patients in each group receiving routine care and comfortable care. The wound healing time, visual analog scale, quality of life score, the level of inflammatory factors, the incidence of complications, and patient satisfaction were compared between the 2 groups. The average time of wound healing in the observation group was significantly lower than that in the control group (P < .01). The satisfaction rate in the observation group was significantly higher than that in the control group (P = .029). Meanwhile, the results showed that visual analog scale and quality of life scores in the observation group was significantly improved than that of the control group after receiving intervention (P < .05). After receiving intervention, the levels of TNF-α and IL-6 of patients in both groups were decreased, and the levels of TNF-α and IL-6 in the observation group were significantly decreased than those in the control group. Moreover, the incidence rate of adverse reaction in the observation group was significantly lower than that in the control group (P < .01). Comfortable nursing can reduce the wound healing time, the postoperative pain level, the incidence of complications, and improve patient satisfaction, which is of great significance for the prognosis of VSD in patients with orthopedic trauma.
