BACKGROUND Currently,pediatric surgeons are challenged by a lack of consensus on the optimal management strategy(conservative or surgical)for children with Bell’s stage II necrotizing enterocolitis(NEC).AIM To evaluate the clinical efficacy of peritoneal drainage in very-low-birth-weight(VLBW)neonates with modified Bell’s stage II *** This was a retrospective analysis of 102 NEC(modified Bell’s stage II)neonates born with VLBW who were treated at the Fujian Children’s Hospital(Fujian Branch of shanghai Children’s Medical Center)between January 2017 and January 2020;these included 24 cases in the peritoneal drainage group,36 cases in the exploratory laparotomy group,and 42 cases in the conservative treatment *** The general characteristics were comparable in the three groups(P>0.05).Compared with conservative treatment,peritoneal drainage was associated with significantly shorter fasting time,abdominal distension relief time,fecal occult blood(OB)negative conversion time,and reduced hospital length of stay(HLOs)(Pspite some advantages of peritoneal drainage over conservative treatment in terms of cure,conversion to laparotomy,intestinal perforation,intestinal stenosis,and abdominal abscess rates,the differences were not statistically significant(P>0.05).Compared to exploratory laparotomy,the fecal OB negative conversion time was significantly shorter in the peritoneal drainage group(Psimilarly,the exploratory laparotomy group showed longer fasting time,abdominal distension relief time,HLOs,and higher complication rate compared to peritoneal drainage group,but the between-group differences were not statistically significant(P>0.05).CONCLUsION Peritoneal drainage,an easy-to-operate procedure,can improve the clinical symptoms of VLBW neonates with Bell’s stage II NEC and help reduce the HLOs.

Identification of components and metabolites of traditional Chinese medicines(TCMs)employing liquid chromatography-quadrupole time-of-flight mass spectrometry(LC-Q-TOF Ms)techniques with information-dependent acquisition(IDA)approaches is increasingly frequent.A current drawback of IDA-Ms is that the complexity of a sample might prevent important compounds from being triggered in IDA *** window acquisition of all theoretical fragment-ion spectra(sWATH)is a dataindependent acquisition(DIA)method where the instrument deterministically fragments all precursor ions within the predefined m/z range in a systematic and unbiased ***,the superiority of sWATH on the detection of TCMs’components was firstly investigated by comparing the detection efficiency of sWATH-Ms and IDA-Ms data acquisition modes,and sanguisorbin extract was used as a mode *** optimizing the setting parameters of sWATH,rolling collision energy(CE)and variable Q1 isolation windows were found to be more efficient for sanguisorbin identification than the fixed CE and fixed Q1 isolation *** importantly,the qualitative efficiency of sWATH-Ms on sanguisorbins was found significantly higher than that of IDA-Ms data *** IDA mode,18 kinds of sanguisorbins were detected in sanguisorbin extract.A total of 47 sanguisorbins were detected when sWATH-Ms was used under rolling CE and flexible Q1 isolation window ***,26 metabolites of sanguisorbins were identified in rat plasma,and their metabolic pathways could be deduced as decarbonylation,oxidization,reduction,methylation,and glucuronidation according to their fragmental ions acquired in sWATH-Ms ***,sWATH-Ms data acquisition could provide more comprehensive information for the component and metabolite identification for TCMs than IDA-Ms.

TiN coating was prepared by reactive plasma spraying in the Ar and N2 containing plasma jet. The resuits of XRD show that the TiN coating consists of TiN and Ti3 O, neither Ti2 N nor TiO2 phases. The toughening mechanism was characterized by analyzing the sEM morphologies of the TiN coating＇s indentation of microhardness and fracture surfaces. The results indicate that the coating possesses a high toughness. The adhesion strength among the TiN layers is 25.88 MPa, which is slightly lower than that of the Ni/AI bonding coating. The oxidation process of the RPs TiN coating is TiN→Ti3 O→TiO2.

介绍李点教授从虚论治胃胀的学术观点及临床经验。胃胀为临床常见病,可单独出现,也可作为兼症出现在其他疾病过程中,多表现为胀满作痛等实证,单纯使用攻法或下法,常难以根治。李点教授认为“至虚有盛候”,因素体不足,或病久失治、误治,或反复发作,胃胀属虚证、虚中夹实、真虚假实者常见,则当从虚论治,以健脾益气、滋阴益胃、温阳健脾、扶正祛邪为法;久病多虚、以补助消,以润胜燥、降浊和胃,慎辨虚实、补泻并用,巧用药对,调畅气机为临证特色,常取得良好的疗效。
