Objective To compare the response of haemodynamics and intraocular pressure (IOP) to laryngeal mask airway (LMA) and tracheal intubation (TT) in children with glaucoma.Methods A prospective,randomized study was conducted in 50 glaucomatous children,scheduled to undergo trabeculectomy and divided into LMA group (25 cases) and TT group (25 cases) by random digits table method.Endotracheal intubation or placement of the laryngeal mask operation time and the dosage of midazolam was noted in each patient.Heart rate (HR),mean arterial pressure (MAP),tip perfusion index (TPI),IOP were measured after anesthesia induction (T1),endotracheal intubation or placement laryngeal mask immediately (T2),endotracheal intubation or placement after laryngeal mask 1 min (T3),2 min (T4),3 min(T5),5 min(T6).Results There was no significant difference in endotracheal intubation or placement of the laryngeal mask operation time and the dosage of midazolam between two groups (P ＞ 0.05).Compared with T1,HR,IOP were increased at T2-T4,MAP was increased at T2-T3,TPI was decreased at T2-T5 in TT group,there was significant difference(P ＜ 0.05).There was no significant difference in HR,MAP,TPI,IOP among different points in LMA group (P ＞ 0.05).HR,MAP,IOP in LMA group at T2-T4 were lower than those in TT group [HR:(119.3 ±8.9),(117.6 ±8.5),(115.2 ±6.9) beats/min vs.(131.3 ±7.1),(128.1 ±6.8),(123.2 ± 8.6)beats/min,MAP:(36.9 ± 5.1),(37.1 ±4.8),(34.7 ±4.6) mmHg (1 mmHg =0.133 kPa) vs.(44.1 ± 4.9),(42.8 ± 5.5),(41.9 ± 7.1) mmHg,IOP:(27.6 ± 2.5),(27.0 ± 2.0),(25.9 ± 2.3) mmHg vs.(34.2 ± 2.2),(32.9 ± 1.6),(31.1 ± 2.2) mmHg],TPI at T2-T5 was higher than that in TT group (3.25 ± 0.28,2.99 ± 0.26,3.15 ± 0.31,3.40 ± 0.30 vs.2.69 ± 0.29,2.22 ± 0.27,2.41 ± 0.30,2.66 ± 0.33),and there was significant difference (P ＜0.05).Conclusion Insertion of LMA in glaucomatous children is not associated with significant changes in haemodynamics and IOP response and offers advantages over tracheal intubation.

Furbenicillin is a broad-spectrum semisynthetic penicillin with strong antibacterial activity against Gram-negative bacteria. Furbenicillin sodium is determined by volumetric method in current criteria. However, the criteria does not contain an assay of related substances of furbenicillin sodium. In this study, we established a method for detection and analysis of furbenicillin sodium and its related substances by HPLC. The analysis was performed with a C18 column under a gradient elution, the detection wavelength was 225 nm, and the column temperature was 35 degrees C. The reliability and accuracy of established method was validated in this study. Pure samples of furbenicillin sodium and its related substances were prepared. The structures, biological activities, and chromatographic retention behaviors of furbenicillin sodium and its related substances were identified using NMR, CLSI agar dilution method, and HPLC. All results in the current study provide ample evidence that this method is able to determine the reasonable limits in the quality-control protocol for furbenicillin sodium.

Objective To investigate the clinical efficacy of nerve growth factors in the treatment of sudden deafness.Methods A retrospective analysis was performed on 124 cases of hospitalized patients who suffered from unilateral sudden deafness from November 2013 to February 2015.The patients were divided into two groups: 59 in the treatment group and 65 in the control group.Each group was further divided into four subgroups according to different audiometric curves: the low-frequency declining type, the high-frequency declining type, the flat type, the completely deafness type.The control group: the patients were treated with the conventional therapy according to different audiometric curves.The treatment group: intramuscular mouse nerve growth factor treatment was added on the basis of conventional therapy mentioned above.The both treatments lasted 10 days.The total efficiency of two groups was compared ,and the efficiency of the subgroups was also compared.Results The total efficiency of the treatment group was 64.40% and 44.62% for the control group.The total efficiency of the treatment group was significantly higher than the control group.The analysis revealed as having statistically significant differences (x2=4.877,P=0.032<0.05).The total efficiency of the sub-groups by different audiometric curves was further analyzed.All the total efficiency of the sub-groups in treatment group were higher than the sub-groups in the control group, but the results were notconsidered as significantly different(P>0.05).Conclusion The mouse nerve growth factor has a positive effect on the treatment of sudden deafness, and has shown the acceptable clinical efficacy without side-effect.Thus the mouse nerve growth factor is a safe and effective drug for treating sudden deafness.

Objective To assess whether there was strong association between antiphospholipid antibodies(APA) and coronary heart disease(CHD), to study the environmental factors of APA production and APA pathogenic mechanism in patients with CHD.Methods Blood samples from 76 patients with CHD and 30 controls were tested for anticardiolipin antibodies IgG(ACA-IgG),human cytomegalovirus IgG,IgM(HCMV-IgG,IgM) by enzyme-link immunosorbant assay(ELISA) and 6-keto-PGF1a,endothelin(ET) by radioimmunoassay(RIA).Results A total of 27 patients(35.53%) were ACA positive in 76, as compared to 2 of 30(6.67%) healthy individuals, P＜0.05. There was no difference in ACA among acute myocardial infarction(AMI,39.13%), old myocardial infarction(OMI,26.53%), unstable angina pectoris(UA,38.40%), P＞0.05. The number of ACA positive subjects was higher in HCMV infection patients with CHD than no HCMV infectious patients with CHD. There was no PGI2 and ET level difference between ACA-IgG positive and negative CHD.Conclusion There are strong association between APA and CHD. The HCMV infection may be an environmental factor of APA production in CHD patients with raised ACA. The alteration of PGI2 and ET are not the pathogenic mechanism of ACA in patients with CHD.

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.

Pro-inflammatory macrophages play key regulatory role in the occurrence and development of rheumatoid arthritis (RA). In this study, we constructed a celastrol (Cel)-loaded polyamide-amine dendrimer (PAMAM) drug delivery system, which could target folate receptor and mitochondria. It could target inflammatory macrophages and realize chemo-photothermal synergistic therapy. Using PAMAM as the nano-carrier, folate receptor-targeting group folic acid (FA) and mitochondria-targeting group IR808 (also known as the photothermal agent) were conjugated with PAMAM through amide reaction, and then complexed with anti-inflammatory drug Cel to prepare the FA-PAMAM-IR808/Cel nanocomplex. In vitro characterization results showed that the drug loading efficiency of the nanocomplex was 50.90%, particle size was between 130 and 160 nm, average potential was between 1.0 and 3.5 mV, the drug release showed pH sensitivity, temperature reached to 42.5 ℃ after near-infrared (NIR) light irradiation for 10 min. In vitro cellular uptake experiments showed that the nanocomplex had obvious folate receptor-targeting and mitochondria-targeting ability. Following irradiation with NIR light, the cytotoxicity and cellular apoptosis enhanced. The secretion of pro-inflammatory factors tumor necrosis factor α (TNF-α), interleukin (IL)-1β, IL-6 and nitric oxide (NO) decreased in a concentration-dependent manner. This study provided insights for the development of novel anti-RA nanomedicines.

The target compounds were prepared from 5-aminobenzimidazolone by two steps reaction, and their AChE inhibitory activities were measured by Ellman method in vitro. The AChE inhibitory activity of compound 4d is the best of them, and its IC50 value is equal to 7.2 μmol·L(-1), which is better than that of rivastigmine; moreover the 4d had no inhibitory activities to BuChE. Therefore, the inhibitory activities of 5-aminobenzimidazolone derivatives to acetylcholinesterase are worth further researching.
