OBJECTIVE:To optimize the inclusion technology of Eugenol-β-cyclodextrin (β-CD) inclusion complex,and to identify and characterize it. METHODS:With the molar ratio of eugenol to β-CD,inclusion temperature and inclusion time as fac-tors,using the yield of inclusion compounds as index,the inclusion technology was optimized by orthogonal test. The formation of inclusion compound was identified by the spectra change of FT-IR,XRD and 1H NMR. Its structure was characterized by 1H RO-ESY NMR. RESULTS:The optimized inclusion conditions were that the molar ratio of eugenol to β-CD was 1.0:1;inclusion tem-perature was 60 ℃;inclusion time was 2.0 h. And the yield of inclusion compound was 73.86%(RSD=0.17%,n=3). 1H NMR results ofβ-CD and its inclusion complex indicated that the optimum qualitative ratio of the inclusion complex was 1.0:1. The inter-molecular interaction between eugenol and β-CD was confirmed by the spectrum analysis of FT-IR and XRD. 1H ROESY NMR re-sults indicated the structure of inclusion complex mainly was that the phenyl of eugenol was in the cavity of β-CD,the vinyl was outside. CONCLUSIONS:The inclusion technology is reasonable and feasible,and can be used for the inclusion of eugenol andβ-CD. The formation of inclusion compound is confirmed by the spectrum analysis.

Objective: To investigate the proliferation, adhesion, migration, invasion, and contraction capacities of carcinoma-associated fibroblasts (CAFs) in human breast cancer microenvironment. Methods: The protein expressions of fibronectin (FN), alpha-smooth-muscle actin (α-SMA) and fibroblast activation protein (FAP) were detected by Western blotting, so as to distinguish CAFs cells from normal fibroblasts (NFs). The proliferation of CAFs and NFs was detected by Roche xCellingence system, cell counting, and cell counting kit-8 (CCK-8) assay. The adhesion, migration, invasion and contraction capacities of CAFs were evaluated by the cell adhesion experiment, Roche xCellingence system, Transwell invasion assay and collagen gel contraction assay, respectively. Results: The primary CAFs and NFs cells which were isolated from human breast cancer grew in good condition with active proliferation. The linear types and trends of their growth curves were accorded with the cell growth characteristics. While compared with NFs, CAFs had a robust proliferation capacity, and the obviously stronger abilities of adhesion, migration, invasion, and contraction. Conclusion: There are prodigious differences of proliferation and migration between CAFs and NFs cells in human breast cancer microenvironment. CAFs have the stronger abilities of proliferation, adhesion, migration, invasion, and contraction than NFs. Copyright © 2013 by TUMOR.

Nitrous oxide/oxygen is one of the inhaled anesthetics that receives attention by scholars at home and abroad for its unique characteristics of excellence comparing with intravenous sedation analgesia which is more commonly used.

Hepatocellular carcinoma (HCC) is one of the most prevalent and deadly malignancies world-wide,with many patients failing to benefit sustainably from emerging immunotherapies and targeted thera-pies due to drug resistance.Current commonly used biomarkers,such as alpha-fetoprotein (AFP ),tumor mutation burden (TMB),and programmed cell death protein 1 (PD-1),lack efficacy in indica-ting the outcomes of HCC immunotherapy and targeted therapy.Therefore,identifying effective biomark-ers to accurately predict therapeutic efficacy is crucial for optimizing clinical decision-making.Recent studies have shown that N6-methyladenosine (m6 A) modification,one of the most common and important RNA modifications in eukaryotes,plays a significant role in the HCC resistance to immunotherapy and targeted therapy.We summarize the research progress regarding to the roles and mechanisms of m6 A modification and its functional proteins in the resistance to immunotherapy and targeted therapy in HCC,and also discuss the potential application of m6 A modification as biomarkers for predicting the efficacy of these treatments.

INTRODUCTIONBicuspid aortic valve (BAV) is the most common form of adult congenital heart disease. When compared to patients with a normal trileaflet aortic valve, dilatation of the aortic root and the ascending aorta (Asc Ao) are the common findings in patients with BAV, with consequent higher risk of developing aortic aneurysm, aortic dissection and rupture. We aim to determine the site of the Asc Ao where maximum dilatation occurs in Asian adult patients with BAV.

MATERIALS AND METHODSAll subjects underwent full echocardiography examination. The diameter of the Asc Ao was measured at 3 cm, 4 cm, 5 cm, 6 cm and 7 cm from the level of aortic annulus to the Asc Ao in 2D from the parasternal long-axis view.

RESULTSA total of 80 patients (male/female: 45/35; mean age: 45.3 ± 16.2 years) with congenital BAV and 30 normal control group (male/female: 16/14; mean age: 45.9 ± 15.1 years) were enrolled. The indexed diameters of the Asc Ao were significantly larger than the control group. In patients with BAV, maximum dilatation of Asc Ao occurred around 6 cm distal to the aortic annulus.

CONCLUSIONIn patients with BAV, dilatation of Asc Ao is maximal at the mid Asc Ao region around 6 cm distal to the aorta annulus.

OBJECTIVE: To explore the influence of hyperbaric oxygen (HBO) treatment on neural plasticity and it's mechanism in experimental rats with cerebral ischemia. METHODS: Ninety-healthy male adult Sprague-Dawley rats (3 to approximately 4 month old) were randomly divided into a pseudo-operative group, a model group, and an HBO therapy group. The middle cerebral artery occlusion model was duplicated with suture methods, then we used beam walking test (BWT) to determine the motor skill of the rats and immunohistochemistry method to detect the distribution and location of microtubule-associated protein-2 (MAP-2) and glial fibrillary acidic protein (GFAP). Quantitative real-time PCR was used to detect the expression of Map-2 mRNA and GFAP mRNA. RESULTS: Immunohistochemistry showed that the fluorescence gray scale value of Map-2 in the HBO group was the highest in 3 groups at 1st week and 2nd week (P<0.05).The value of GFAP was lower than that of the model group but higher than that of the sham operated group (P<0.05). Real-time fluorescence-quantitative PCR indicated that the Map-2 mRNA of HBO group was the highest in 3 groups at 1st week and 2nd week (P<0.05); but the value of GFAP mRNA in the HBO group is lower than that of the model group,but higher than that of the sham operated group at 1st week and 2nd week (P<0.05). CONCLUSION After cerebral infarction, giving hyperbaric oxygenation treatment can improve the limbs motor function, and hyperbaric oxygenation treatment can increase the expression of Map-2 and decrease the expression of GFAP, which promote neural plasticity.

BACKGROUND: Procalcitonin (PCT), C-reactive protein (CRP), and white blood cells (WBCs) are inflammatory markers used to diagnose severe bacterial infections. We evaluated the diagnostic role of these markers and compared their accuracy for spontaneous bacterial peritonitis (SBP) associated with chronic severe hepatitis B (CSHB). METHODS: PCT and CRP concentrations, WBC count, and other hematological parameters were measured in serum from 84 well-characterized patients with CSHB, of whom 42 had SBP. Receiver operating characteristics (ROC) curve analysis was performed to assess the diagnostic accuracy. RESULTS: PCT and CRP concentrations were significantly higher in the CSHB patients with SBP (n=42) than CSHB patients without SBP (n=42). PCT and CRP concentrations were more accurate than WBC count for the diagnosis of CSHB-associated SBP. The optimal cutoff value of PCT was 0.48 ng/mL. The PCT concentration was significantly correlated with the CRP concentration and WBC count. CONCLUSIONS: Serum PCT and CRP seems to be better markers than WBC for the diagnosis of CSHB patients with SBP.

OBJECTIVETo analyze the epidemiological characteristics of hospitalized children with burn injuries in Fujian Medical University Union Hospital, so as to provide evidence to complete an adequate, timely, and effective prevention and treatment system of children with burn injuries.

METHODSMedical records of children with burn injuries, aged 14 and under, hospitalized in the Department of Burns from July 2012 to June 2015 were collected. Data of gender and age, location and cause of injury, time of injury, state of injury, admission time after injury, first aid, length of hospital stay, and treatment and so on were recorded. They were divided into 4 age brackets: less than or equal to 1 year old, more than 1 year old and less than or equal to 3 years old, more than 3 years old and less than or equal to 7 years old, more than 7 years old and less than or equal to 14 years old, then gender and cause of injury of children in the 4 age brackets were analyzed. Admission months of the children were divided into spring (March to May), summer (June to August), autumn (September to November) and winter (December to February of the following year), and then the cause of injury of children in each season was analyzed. Severities of male and female children, length of hospital stay of children with different causes of injury were analyzed. Data were processed with chi-square test, Wilcoxon rank-sum test.

RESULTSOut of 2 608 inpatients with burn injuries, 1 407 children with burn injuries, aged 14 and under, accounting for 53.9%, were admitted in the recent 3 years. The ratio of male to female was 1.6 ∶1.0. Children more than 1 year old and less than or equal to 3 years old ranked the largest number (68.3%, 961/1 407) in the 4 age brackets. There was statistically significant difference in constituent ratios of gender of children among the 4 age brackets (χ(2)=11.00, P=0.012). One thousand three hundred and seventy-two children were burned indoors (97.5%), while 35 children were burned outdoors (2.5%). Scalding with hot fluids was the most common cause of burn (95.0%, 1 337/1 407). There was statistically significant difference in constituent ratios of injury cause of children among the 4 age brackets (χ(2)=107.23, P<0.01). There was statistically significant difference in constituent ratios of injury cause of children more than 7 years old and less than or equal to 14 years old compared with those of the other 3 age brackets (with χ(2) values from 12.88 to 119.85, P values below 0.01). Most burn accidents occurred between 17: 00-20: 59 (33.5%, 472/1 407). Burns were more likely to happen in April to October. July (10.4%, 146/1 407) and August (10.5%, 148/1 407) were the crest-time. Most of the children were burned in summer (35.3%, 496/1 407). There was statistically significant difference in the injury cause of children among each season (χ(2)=14.61, P=0.024). The burn degrees of male and female children were mainly mild or moderate, and there was no statistically significant difference in the severity (Z=-0.39, P>0.05). The trunk was the most involved anatomic site (61.1%, 859/1 407). Most of children were admitted to hospital within 2 hours post burn (79.7%, 1 121/1 407). Majority of children were taken off clothes as first aid on spot or did not receive any treatment. Most of the children were discharged within 2 weeks after admission (80.0%, 1 126/1 407). There was statistically significant difference in length of hospital stay of children with causes of hot liquid scald, flame burn, electric burn, high temperature solid burn, chemical burn (χ(2) =17.33, P=0.002). Most of the children were treated with non-surgical methods, and the majority of the children got better condition or totally recovered and then discharged.

CONCLUSIONSThe majority of hospitalized children with burn injuries in our unit are young boys in preschool period, who were burnt by hot fluid at the time of dinner and bathing at home during summer. So we should make more effort on popularization of prevention about burn.
