Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

Objective To investigate the effects of diclofenac sodium suppositories on emergence agitation after sevoflurane maintenance in children undergoing adenotonsilleetomy. Methods Forty-five patients selected for adenotonsillectomy were randomly divided into three groups (n=15). Patients in group 1 were given diclofenac sodium suppositories 12.5 mg right after intubation, those in group 2 were given diclofenac sodium suppositories 12.5 mg immediately after operation, while those in control group were not treated with diclofenac sodium suppositories before or after operation. The extubation time and time spent in post-anesthctic ICU (PACU) were recorded, the modified Aldrete score and pain score were assessed after entrance into PACU, and pediatric anesthesia emergence delirium (PAED) scale was administered 10, 20 and 30 rain after entrance into PACU. Results There was no significant difference in extubation time and time spent in PACU among three groups(P>0.05). Ten minutes after entrance into PACU, the PAED score of group 1 was significantly lower than those of group 2 and control group(P<0.05), while there was no significant difference between the latter two groups(P>0.05). Twenty and thirty minutes after entrance into PACU, the PAED scores of group 1 and group 2 were significantly lower than that of control group(P<0.05). There was no significant difference in the modified Aldrete score right after entrance into PACU among three groups. The pain scores of group 1 and group 2 were signifiantly lower than that of control group(P< 0.05). Conclusion Diclofenac sodium suppositories can decrease the incidence and severity of emergence agitation after sevoflurane maintenance in children undergoing adenotonsillectomy.

OBJECTIVETo explore the correlation between pathological characteristics of target organs and excess evil syndrome in IgA nephropathy.

METHODSData were collected in multicenter cooperation. Totally 266 IgA nephropathy patients were typed into exogenous wind-heat affection syndrome (49 cases), lower energizer damp-heat syndrome (100 cases), damp-phlegm syndrome (43 cases), and blood stasis syndrome (74 cases). Meanwhile, percutaneous renal biopsy was performed in all patients for Hass classification, Oxford classification, Katafuchi integral, and Jiang's classification methods. The correlation between excess evil syndrome and pathological index was analyzed.

RESULTSFour syndrome types were correlated with their Hass levels (r = 0. 341, P <0. 01). Affection of exogenous wind-heat syndrome was correlated with segmental proliferation of endothelial cells and damaged active lesions of segmental capillary loops. Lower-energizer damp-heat syndrome was associated with Hass III level, destroying active lesions of capillary loops, segmental proliferation of endothelial cells, glomerular segmental lesions, focal interstitial infiltration of inflammatory cells, focal interstitial fibrosis and tubular atrophy. Blood stasis syndrome was associated with Hass IV level, glomerular sclerosis, segmental glomerulosclerosis (S)/adhesion, mesangial hypercellularity (M), angiohyalinosis, multi-foci interstitial infiltration of inflammatory cells, multi-foci interstitial fibrosis and tubular atrophy. Phlegm-damp syndrome had higher proportions of Hass I and III levels, but with no association with other pathological parameters.

CONCLUSIONSExcess evil syndrome was associated with partial pathological characteristics of IgA nephropathy. It could reflect pathological damage degree of target organs, activities, chronic lesions, and prognosis of IgA nephropathy to certain extent. Correlated pathological characteristics and its evolution could indicate excess evil syndrome types and their evolution rules.

AIMTo study the effect of angiotensin II (Ang II) on platelet-derived growth factor(PDGF) receptor expression in vascular smooth muscle cell(VSMC).

METHODSRestenosis model was established by balloon injury in rat aorta. The morphologic change and level of Ang II were measured at 14th day after operation. The expression of PDGF-beta receptor was detected by Western blot. The cultured VSMC pretreated with or without losartan were treated with Ang II.

RESULTSCompared with sham group, the sections of injured aorta showed marked intimal thickening with large numbers of VSMCs proliferation throughout intima and media, the level of Ang II obviously increased by 78.8% (P < 0.05), the expression of PDGF-beta receptor significantly increased by 83.9% (P < 0.05) at 14th day after operation. The expression of PDGF-beta receptor in cultured VSMC treated with Ang II was higher than that of control group (P < 0.01). The effect of Ang II was inhibited remarkably by pretreatment with losartan.

CONCLUSIONAng II can stimulate PDGF receptor expression in VSMC, it may be an important mechanism of Ang II-induced VSMC proliferation.

OBJECTIVETo analyze the changes in endogenous small molecule metabolites after benzo[a]pyrene (B[a]P) exposure in rat cerebral cortex and explore the mechanism of B[a]P neurotoxicity.

METHODSFive-day-old SD rats were subjected to gavage administration of 2 mg/kg B[a]P for 7 consecutive weeks. After the exposure, the rats were assessed for spatial learning ability using Morris water maze test, ultrastructural changes of the cortical neurons under electron microscope, and metabolite profiles of the cortex using GC/MS. The differential metabolites between the exposed and control rats were identified with partial least squares discriminant analysis (PLS-DA) and the metabolic pathways related with the differential metabolites were analyzed using Cytoscape software.

RESULTSCompared with the control group, the rats exposed to B[a]P showed significantly increased escape latency (P<0.05) and decreased time spent in the target area (P<0.05). The exposed rats exhibited widened synaptic cleft, thickened endplate membrane and swollen cytoplasm compared with the control rats. Eighteen differential metabolites (VIP>1, P<0.05) in the cortex were identified between the two groups, and 9 pathways associated with B[a]P neurotoxicity were identified involving amino acid metabolism, tricarboxylic acid cycle and Vitamin B3 (niacin and nicotinamide) metabolism.

CONCLUSIONB[a]P can cause disturbance in normal metabolisms and its neurotoxicity is possibly related with disorders in amino acid metabolism, tricarboxylic acid cycle and vitamin metabolism.

OBJECTIVETo extract the active component from the root of Actinidia valvata Dunn and to investigate the effects on hepatocellular carcinoma (HCC) cells in vitro.

METHODSTotal saponin was extracted from the root of A. valvata (TSAVD). HCC cells, such as BEL-7402, HepG2, PLC, SMMC-7721, MHCC-97-H, and MHCC-97-L, were treated with TSAVD in 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenytetrazolium bromide (MTT) assay. BEL-7402 and MHCC-97-H cells were also treated respectively with TSAVD at different concentrations for 24 h in wound healing and adhesion assays, and the effects of TSAVD on BEL-7402 and MHCC-97-H cells mobility and adhesion abilities were observed. Meanwhile, the effects of TSAVD on invasion and migration of BEL-7402 and MHCC-97-H cells were also investigated by transwell chamber in invasion and migration assays.

RESULTSTSAVD at 1.5 mg/mL inhibited BEL-7402 cell proliferation with inhibition ratios (IRs) of 61.08%, 74.12%, 84.55% at 24, 48, and 72 h, respectively. Meanwhile, TSAVD inhibited MHCC-97-H proliferation in a concentration-dependent manner from 1.5 to 0.5 mg/mL, with the IR of 36% at 1.5 mg/mL at 24 h. For SMMC-7721, PLC, and HepG2, the IR was lower than 30% at 1.5 mg/mL at 24 h. In the wound healing assay, mobility abilities of BEL-7402 and MHCC-97-H cells in TSAVD treated groups were significantly weaker than those of the control group. After pretreatment for 24 h with TSAVD, adhesion abilities were reduced in both MHCC-97-H and BEL-7402 cells, with IRs of 48.50%±4.86% and 49.85%±5.25% at 200 μg/mL. The IRs of MHCC-97-H and BEL-7402 cells in the migration assay were 49.13%±2.91% and 79.37%±0.09% at 200 μg/mL. In the invasion assay, IRs were 69.78%±4.88% and 82.48%±0.25% at 200 μg/mL.

CONCLUSIONSOf all HCC cells, the highest inhibition by TSAVD was seen for BEL-7402 proliferation. TSAVD could restrain adhesion, invasion, mobility, and migration abilities of BEL-7402 and MHCC-97-H cells in vitro.

Objective:To investigate the prevalence of dysphagia in old people in nursing homes in Ningbo and analyze its related factors. Methods:From August, 2017 to April, 2018, 997 people aged 60 or above were selected from eight nursing homes in four districts in Ningbo. They were investigated with general questionnaire, Kubota water swallowing test, body mass index (BMI) and Quality of Life Index (QLI), and the data were analyzed with Logistic regression. Results:There were 259 (25.98%) persons with dysphagia. Age, male, hypertension, diabetes, hyperlipidemia, coronary heart disease, stroke and fracture were risk factors for dysphagia (P < 0.01). There were 19.2% with low BMI in total, and 63.3% for dysphagia. The total score of QLI decreased with age (F = 18.706, P < 0.001), more in males than in females (t = 2.516, P = 0.012), and less in those with dysphagia than with normal swallowing (t = 7.176, P < 0.001). Conclusion:Dysphagia is prevalent in the old people in nursing homes in Ningbo, which needs early intervention.

Objective:To assess the usage of β-blocker in patients with acute myocardial infarction (AMI) in early hospitalization period (admission within 24 hours) in Liaoning Province from 2001 to 2011.Methods:By convenience sampling, patients from 10 hospitals in 3 study years (2001, 2006, and 2011) were randomly selected and clinical data were extracted, the usage frequency, types and dosage of β-blocker were analyzed.Results:A total of 1 365 AMI patients from ten hospitals were included in this analysis, and about 296 cases (21.68%) were considered as ideal patients for early β-blocker use (53.10% cases in 2001, 68.70% cases in 2006, and 78% cases in 2011, P<0.001).Logistic regression analysis showed that the heart rate was related to the early usage of β-blocker.The most frequently used β-blocker was metoprolol (90.73%) within 3 years, only 1.46% had the dosage above 50 mg.Conclusions:During the past decade, the utilization rate of βB among the appropriate patients with AMI during the early-phase hospitalization in Liaoning Province present the increasing trend.However, there is a distinct gap between the utilization status and guideline.Although the early application can reduce the occurrence of cardiovascular event, the heart rate of patients and so on are the main causes that influence its application.Therefore, regarding the early application, it is necessary to comply with the evidence-based medical science and combine it with the individualization principle.
