Objective To investite the effect of endotoxin pretreatment on lung injury induced by hepatic ischemia reperfusion in rabbits and its mechanism. Method Forty-eight New Zealand white rabbits were randomly divided into4 groups with 12 rabbits each group:routine control group,pretreatment control group,ischemia reperfusion group (IR group), and preperfusion group( LPS + IR group). Rabbits of routine control group received operative dissector only, and those of pretreatment control group received pretratment of daily intraabdominal injection of lipopo|ysaccharide(O.5,0.5,and 1.0 mg/kg,respectively)in the 3 days before operative dissector.Livers of IR group were rendered and ischeraic for 30 minutes, and repeffused for up to 4 hours. Rabbits of LPS +IR group received the preueaunent before heretic ischemia repeffusion. Four hours after reperfusion, serum endotoxin,tumor necrosis factor-α(TNF-α), wet/dry ratio and broncho-alveolar lavage fluid protein content of lung,malondialdehyde(MDA) and mpenrxide dismutase(SOD) in lung homogenate, lung injury ratio, and activity of Nuclear factor-kB(NF-kB) in alveolar macrophage wene examined. Differences within the groups were analyzed using One way ANOVA. Results Between the two control groups,there were no significant differences in all indexes(P>0.05). The TNF-α[ (48.31±5.31)pg/ml vs.(56.47±5.09)pg/ml, P<0.01],wet/dry ratio [(4.98±0.33)vs. (5.22±0.31), P = 0.03],broncho-alveolar hvage fluid protein content[(0.68±0.11)g/L vs. (0.76±0.10)g/L, P =0.04],MDA[(0.86±0.06)nmol/mg vs. (0.93±0.07)nmol/mg, P =0.02],lung injury ra-tio[(13.4±4.3)% vs. (17.4±4.1)%, P = 0.03],and the activity of NF-gB[(5.82±1.12)OD/mm2 vs.(7.40±1.26)OD/mm2, P<0.01] in alveolar macrophage of the LPS+ IB group were all significantly lower than those of IB group, while the SOD[ (90.30±7.38 )U/rag vs. (84.44±7.90 )U/rag, P = 0.04]of LPS + IR group was significantly higher than that of IR group. Conclusions Endotoxin pretrealment may ameliorate the lung injury induced by hepatic isehernia reperfusion. The mechanism may be that endotoxin pretreatment deoreases production of serum TNF-α and the activity of NF-kB in alveolar maerophage.

Objective To investigate the efficacy of standardized protocol,including prenatal diagnosis,perinatal management and treatment,on babies with meconium peritonitis.Methods A standardized protocol with prenatal diagnosis,perinatal management,treatment and follow-up on congenital anomaly was founded by Capital Institute of Pediatrics and several other obstetric hospitals.Thirty neonates diagnosed as meconium peritonitis prenatally from March 15,2006 to August 27,2012 were intervened according to this protoccl.The data of diagnosis,treatment after birth and prognosis were analyzed.Results (1) Prenatal diagnosis:Abnormal meconium peritonitis relative signs were found by ultrasound in all of these 30 cases.Among them,23 cases presented with intestine dilation,15 with polyhydromnios,nine with ascites,four with abdominal cystic mass and four calcification.(2)Diagnosis after birth (n=27):The most common imaging findings in abdominal X-ray were distention (27 cases),dilated intestine with air-fluid levels (22 cases) and calcification (11 cases).The most common imaging findings in ultrasound were obvious intestinal dilation (19 cases),cystic mass (7 cases) and calcification (7 cases).(3) Operation:Except for three cases without symptoms,the other 27 infants received operation at averagely 42 hours after birth (12 h-5 d).Besides the basic treatment as removal of the fuci and dissection of adhesion,peritoneal drainage was performed in one infant,two-stoma enterostomy in seven infants,inverted T-shape enterostomy in eight infants and primary intestinal anastomosis in 11 infants.Among these 27 cases,24 cases were cured,2 cases refused following treatment after surgery and one case was lost to follow up.Conclusions Standardized protocol with prenatal diagnosis,perinatal management and earlier intervention might improve the prognosis of meconium peritonitis.

In this study, the anti-HBV effects of tea polyphenols (TP) were examined. After cells were exposed to TP for 3, 6, 9 days, amounts of HBsAg, HBeAg and HBV-DNA released into the supernatant of the cultured HepG2 2.2.15 cells were detected. TP, to some extent, inhibited the secretion of HBsAg and strongly suppressed the secretion of HBeAg in a dose-dependent (P<0.01) and time-dependent manner, with 50% maximal inhibitory concentration (IC50) value being 7.34 microg/mL on the 9th day, but the time-dependence was not significant (P=0.051). Expression of HBV-DNA in the supernatant of the cell culture also was significantly decreased in a dose-dependent fashion (P<0.01). The IC50 of TP in inhibiting HBV DNA was 2.54 microg/mL. It concluded that TP possessed potential anti-HBV effects and may be used as a treatment alternative for HBV infection.

ObjectiveTo observe the influence of mitochondrial cytochrome c oxidase(COX) decrease on cholinergic and dopaminergic system in brain of model rats.MethodsRats were administrated with 1mg/kg/h or 2mg/kg/h subcutaneously via an Alzet minipump for 30 days. Choline-acetyl-transfertase(ChAT) and acetylcholinesterase(AChE) activity in hippocampus and cortex of rats were measured by radiochemical method and hydroxylamine colorimetry separately. The contents of Norepinephrine(NE), dopamine, 5-hydroxytryptamine(5-HT) and their metabolic products in striatum were measured by HPLC.ResultsChAT activity was significantly inhibited in hippocampus and cortex of model rats, however, the activity of AChE increased in hippocampus and was not affected at the cortex. Therefore, the ratio of ChAT/AChE decreased in model rats. The content of NE, dopamine, 5-HT and their metabolic products in striatum were not different among all groups.ConclusionsCOX deficiency can induce abnormality of ChAT and AChE activity in model rats. Dysfunction of neurotransmitter-acetylcholine would be account for learning-memory deficiency. Model rats indicated cholinergic system deficit without any dopaminergic system abnormality, so chronic infusion of sodium azide via minipump may specially serve as a tool for developing the experimental model of Alzheimer's disease.

Objective:To investigate the treatment and prognosis of children with propionic acidemia (PA).Methods:This study involved 82 children with PA treated in the Department of Pediatric Endocrinol-ogy and Genetic Metabolism, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from December 2002 to June 2020. Clinical data, including manifestations, laboratory test results, treatment strategy, and follow-up data, were summarized and analyzed using t-test or Mann-Whitney U test. Results:(1) Among the 82 cases consisting of 50 (61.0%) boys and 32 (39.0%) girls, 59 (72.0%) were diagnosed after clinical onset; 22 (26.8%) were diagnosed by newborn screening, including eight asymptomatic ones; the other one (1.2%) was asymptomatic but confirmed after the diagnosis of PA in the patient's sibling. The average age at first onset was 4.5 months (2 d-5 years) in 73 subjects, of which 28 (38.4%) were early-onset PA (within three months after birth). (2) Cranial MRI was performed on 26 cases, and abnormality was identified in 19 (73.1%) cases. (3) Hyperlactatemia was found in 16 cases among 30(53.3%) who underwent relevant examination with the average lactic acid level of 3.5 (2.1-4.3) μmol/L, while 35 out of 40 patients (87.5%) had hyperammonemia with an average blood ammonia level of 105.4 (34-907) μmol/L. (4) Among the 28 early-onset PA cases, 16 (57.1%) died, and 12 (42.9%) survived. There was no significant difference in the serum propionylcarnitine level, propionylcarnitine to acetylcarnitine ratio, urine 3-hydroxypropionic acid, or methylcitrate level between the survival and death cases. (5) Genetic mutations were detected in 75 patients (91.5%), among which 26 (34.7%) carried PCCA gene mutations and 48 (64%) with PCCB gene mutations. One patient (1.3%) harbored one known pathogenic mutation in each of the PCCA and PCCB genes. All mutations were inherited from the parents. (6) Followed up to June 2020, 57 (69.5%) patients survived, and 25 (30.5%) died from multiple organ failure secondary to severe acidosis, including 16 early-onset and nine late-onset cases. Conclusions:The primary treatment of PA is dietary control. Most PA patients are diagnosed after clinical onset, but symptoms may recur and even have developmental retardation despite treatment. Some of those diagnosed through newborn screening are asymptomatic after treatment. Newborn screening using tandem mass spectrometry is recommended for early diagnosis and treatment of PA.

Objective To investigate the current status of agitated behaviors among institutionalized elderly with dementia. Methods The Cohen-Mansfield Agitation Inventory (CMAI) and General Information questionnaire were used to collect information of agitated behaviors among 141 institutionalized elderly with dementia in a long-term care facility in Guangzhou. Results Nearly 90.07％(127/141) of the elderly with dementia had the symptoms of agitation. Among the four categories of the agitated behaviors, the incidence for physically non-aggressive behaviors (82.27％, 116/141) was the highest, followed by physically aggressive behaviors (78.72％ , 111/141), verbally non- aggressive behaviors (74.47％, 105/141) and verbally aggressive behaviors (64.54％, 91/141). Spitting, repetitive sentences or questions, complaining occurred frequently. Conclusions The incidence of the agitated behaviors was high and the manifestation and types of agitated behaviors were varied, which should be paid attention to by the institution. It is necessary to develop the personalized, systematic, standardized nursing intervention to provide the support for caregivers and help the elderly with dementia to cope with agitation.
