Chinese Journal of Hepatobiliary Surgery 2017;23(4):277-281
Tumor recurrence is the main factor affecting the postoperative prognosis of hepatocellular carcinoma.The forecast of tumor recurrence by monitoring biomarker can effectively improve the prognosis of such disease.To improve the detection rate of early cancer recurrence can be achieved by detecting the level of the alpha-fetoprotein (AFP),Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3),des-γ-carboxyprothrombin (DCP),or combined detection.In recent years,the researches on the miRNA and Long Noncoding RNAs (LncRNA),which are key regulators in the upstream of signal pathways,could provide a new way for HCC recurrence monitoring.The combined detection of biomarkers in different control levels,maybe is the effective measure to improve the tumor recurrence detection rate,and is also the focus of the further research.

Objective To study the effect of temperature on the emission of tbrmaldehyde trom the blockboard.Methods A 0.25 m3 simulation chamber was used to explore the emission of formaldehyde from blockboard at the temperature of 15,17,19,21, 23,25,27,and 29 ℃,respectively.The relative humidity,the ventilation velocity and the loading factor in simulation chamber was (50?1)%,1.0 L/min,and(1?0.03)m~2/m~3 respectively.Results A hyperbolic logarithm variation in formaldehyde concentration with time in the chamber was observed at different temperatures.Formaldehyde concentration in the chamber increased remarkably once the temperature exceeded 25 C.The chamber stabilization formaldehyde concentration varied with temperature in accordance with an exponent equation of y=0.921 9?0.024 9e~(0.176 4x)(R~2=0.996 9).Conclusion The temperature can greatly influence formaldehyde emission from the blockboards.Higher temperature will facilitate formaldehyde emission from the blockboards.
3.Recognition of anti-VEGF therapy base on the mechanism of VEGF in wet age-related macular degeneration
Chinese Journal of Experimental Ophthalmology 2012;30(4):289-292
Age-related macular degeneration (AMD) is the leading cause of visual impairment among older population worldwide,and wet AMD is more threatened to vision because of the choroidal neovascularization.Some physical therapies are thought to destroy the lesions but can not improve the visual acuity.Therefore,anti-VEGF drug therapy is becoming a new approach to the management of wet AMD.Vascular endothelial growth factor(VEGF) is thought to play an important role in the complicated pathogenesis,which can be addressed by disease reduction strategies.Among the anti-VEGF drug therapies,anti-VEGF monoclonal antibodies are proved to maintain and improve visual acuity.Other therapies have been or now being developed for the treatment of neovascular AMD with the goal of inhibiting VEGF.These inhibitors include VEGF receptor decoy aflibercept,small interfering RNA-based therapies (bevasiranib) and tyrosine kinase inhibitors (vatalanib),which could offer the potential for further advances.To completely realize the active mechanism of VEGF in wet AMD is helpful for the rational use of anti-VEGF drugs.

Objective To explore effects of fosinopril and losartan on renal Klotho expression and oxidative stress in spontaneously hypertensive rats (SHR) and the mechanisms underlying the protection against renal damage. Methods Fifteen male SHRs (22 weeks old) were randomly divided into 3 groups (n=5 in each group): a SHR group, a fosinopril group [10 mg/(kg?d)], and a losartan group [50 mg/(kg?d)]. Age-matched Wistar-Kyoto (WKY) rats were chosen for a control group. Eight weeks later, tail arterial pressure, 24 hours urinary protein (Upro),urinary N-acetyl-β-D-glucosaminidase (NAGase) were measured. Renal pathological changes were examined under light microscopy by HE staining. The renal mRNA and protein expression of Klotho were determined by RT-PCR, immunohistochemical staining or Western blot. The levels of total antioxidant capacity (TAOC), malondialdehyde (MDA), Cu/Zn superoxide dismutase (Cu/Zn-SOD), Mn superoxide dismutase (Mn-SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) were determined.Results The typical pathological characteristics of hypertensive renal damage were observed in the kidney of the SHR group.Compared with the SHR group, the systolic pressure, Upro, and urinary NAGase, the content of MDA and renal pathological damage was reduced while the renal Klotho expression and activities of TAOC, Cu/Zn-SOD, CAT, and GSH-Px were increased (P<0.05 or P<0.01) in the fosinopril or losartan group. There was no significant difference in renal Mn-SOD level among the 4 groups (P>0.05). Conclusion Fosinopril and losartan can exert protection against hypertensive renal damage through upregulating Klotho expression as well as reducing oxidative stress.

Objective: By taking the holism and differentiation concepts of traditional Chinese medicine (TCM) as the guidance, physical, mental and workplace factors were recruited in the observation of depression in employees, and were systematically classified to establish a workplace-related Liver Meridian-depression scale, for providing an evaluation index for depression in employees. Methods: NVIVO 11 software was adopted to assort ancient TCM classics. Based on the holism and differentiation concepts of TCM and well-developed scales, the item pool was determined via brain storm and screened by Delphi method after classified; a Wechat questionnaire was handed out 240 times via the online system 'Wen Juan Xing', and the results were statistically analyzed by the SPSS 17.0 version software. Results: Five dimensions consisting of 80 items were obtained after classification, and 60 items were selected by Delphi method; a total of 216 questionnaires were returned and the return rate was 90%. Of which, 215 questionnaires were valid ones, and the valid rate was 99%. By exploratory factor analysis (EFA), 44 items were obtained, and the aggregate split-half reliability coefficient was 0.922. The Cronbach's alpha coefficient for the five dimensions, i.e. Liver Meridian, relevant meridians, basic psychological activities, work cognition and emotional reactions, was respectively 0.841, 0.842, 0.914, 0.836 and 0.839, indicating a content internal consistency. The score of each item was highly correlated with the corresponding dimension, and the intercommunity was between 0.474 and 0.801. Nine factors were generated, 2 in the dimension of Liver Meridian, 3 in the dimension of relevant meridians, 2 in the dimension of basic psychological activities, 1 in the dimension of work cognition, and 1 in the dimension of emotional reactions, and the load of each factor was between 0.438 and 0.859. The reliability and validity of the scale were well examined. Conclusion: The scale can be applied to evaluate the qi activities of Liver Meridian and depression symptoms related to workplace.

The antagonism of two strains B1 and B2 of Bacillus spp. against pea root rot pathogen Fusarium oxysporum f. sp. pisi was studied. The result of pairing culture showed that B1 and B2 strains of Bacillus spp. had strong antifungal activity to the pathogen. The colonial color of the pathogen changed from gray to white, aerial hyphas increased and entangled into group after treatment with the cell-free fermentational filtrate of B1 or B2. Observation under optical microscope showed that hyphas and spores of the pathogen swelled and distorted with concentrated cytoplasm after treatment, the spores could not germinate or germinated abnormally . A lot of vesicles appeared at the top of the hyphas, and the hyphas stopped growing and broke finally, their cytoplasm spilled from the cell. The cell-free fermentational filtrate of B1 or B2 strains contained 1795.53?g/mL and 1345.93?g/mL protein respectively, from which two antifungal proteins of 103.5 kD (B1 ) and 127.6 kD (B2) were purified.

Aim To compare the bioavailability of two ubiquinone tablets in healthy volunteers. Methods A HPLC method was used to determine the serum ubiquinone 10 concentrations at 0,1,2,3,4,6,8 and 12 h after oral administration for 7 days ( 20 mg, tid ) in a cross-over test. Results AUC, Cmax and Tpeak of the test tablets were (5.91?1.78)?g?h?ml-1 ,(0.66?0.17)?g?ml-1 and (4.00?1.25) h, respectively,and these of the reference tablets were (6.30?2.09)?g?h?ml-1,(0.70?0.20)?g?ml-1 and (4.60?1.58)h , respectively . All of these parameters between the two kinds of tablets were not significantly different statistically. Conclusion The related bioavailability of the test tablets versus the reference tablets is 93.9%. The two formulations of ubiquinone 10 are bioequivalent.
