ABSTRACT
OBJECTIVE@#To investigate the potential mechanisms that mediate the inhibitory effect of porcine recombinant NKlysin (prNK-lysin) against liver cancer cell metastasis.@*METHODS@#HPLC-tandem mass spectrometry was used to identify the differentially expressed proteins in prNK-lysin-treated hepatocellular carcinoma SMMOL/LC-7721 cells in comparison with the control and PBS-treated cells. GO functional annotation and KEGG pathway analysis of the differentially expressed proteins were performed using GO and KEGG databases. RT-qPCR was used to determine the mRNA expression levels of polypeptide-N-acetylgalactosaminotransferase 13 (GALNT13), transmembrane protein 51 (TMEM51) and FKBP prolyl isomerase 3 (FKBP3) in the cells, and the protein expression of FKBP3 was verified using Western blotting.@*RESULTS@#Proteomic analysis identified 1989 differentially expressed proteins in prNK-lysin-treated cells compared with the control cells, and 2753 compared with PBS-treated cells. Fifteen proteins were differentially expressed between PBS-treated and the control cells, and 1909 were differentially expressed in prNK- lysin group compared with both PBS and control groups. These differentially expressed proteins were involved mainly in the viral process, translational initiation and RNA binding and were enriched mainly in ribosome, protein process in endoplasmic reticulum, and RNA transport pathways. RT-qPCR showed that compared with the control group, prNK-lysin treatment significantly increased the mRNA expressions of GALNT13 (P < 0.05) and TMEM51 (P < 0.01) and lowered FKBP3 mRNA expression (P < 0.05). Western blotting also showed a significantly decreased expression of FKBP3 protein in prNK-lysin-treated cells (P < 0.001).@*CONCLUSION@#Treatment with prNK-lysin causes significant changes in protein expression profile of SMMOL/LC-7721 cells and inhibits hepatocellular carcinoma metastasis by downregulating FKBP3 protein and affecting the cellular oxidative phosphorylation and glycolysis pathways.

ABSTRACT
Objective:To study the effects of early breastfeeding volume on neonatal necrotizing enterocolitis (NEC) and feeding intolerance in very low birth weight infants.Methods:This study retrospectively analyzed the clinical data of 275 cases of very low birth weight infants (birth weight<1 500 g) born in Shenzhen Maternity & Child Healthcare Hospital from June 2017 to May 2018. Based on whether breastfeeding or not and the ratio of breast milk intake over the total volume of intake within two weeks after birth, they were divided into three groups: breast milk intake>50% group (>50% group, n=199), breast milk intake≤50% group (≤50% group, n=55) and formula group ( n=21). Differences in the incidence of NEC and feeding intolerance among the three groups were analyzed using Chi-square test (or Fisher's exact test). Effects of breast milk intake on the incidence of NEC and feeding intolerance were evaluated using univariate and multivariate logistic regression analysis. Results:The incidence of NEC in the >50% group, ≤50% group and formula group was 1.5% (3/199), 27.3% (15/55) and 9.5% (2/21), respectively ( P<0.01), and the incidence of feeding intolerance was 17.6% (35/199), 56.4% (31/55) and 28.6% (6/21), respectively ( χ2=34.826, P<0.01). Univariate logistic regression analysis showed that compared with the >50% group, the risk of NEC in the≤50% and formula group increased ( OR=24.500, 95% CI: 6.755-85.594; OR=6.877, 95% CI: 1.081-43.744); that of feeding intolerance increased in the≤50% group ( OR=6.316, 95% CI: 3.293-12.113). Multivariate logistic regression analysis showed that compared with the >50% group, the risk of NEC in the≤50% and formula groups increased ( OR=28.452, 95% CI: 7.280-111.195; OR=8.610, 95% CI: 1.262-58.766); that of feeding intolerance increased in the≤50% group ( OR=7.207, 95% CI: 3.601-14.425). Conclusions:Breastfeeding accounting for more than half of the total volume of intake within two weeks after birth may reduce the incidence of feeding intolerance and NEC in very low birth weight infants.
ABSTRACT
Objective To analyse the risk factors associated with spontaneous intestinal perforation (SIP) in extremely premature infants/extremely low birth weight infants. Method From January 2015 to December 2018, infants with gestational age (GA)<28 weeks or birth weight (BW)<1000 g admitted to our neonatal intensive care unit were enrolled to the retrospective nested case-control study.The clinical data of SIP infants (SIP group) and infants with the same GA but without SIP (control group) were randomly selected and compared. Multivariable Logistic regression was used to analyse the risk factors of SIP. Result A total of 409 extremely premature infants/extremely low birth weight infants were born during the study period. Among them, 25 SIP infants and 55 controls were enrolled. The incidence of SIP in infants with GA 22～25 weeks was 11.8％(16/136), which is higher than infants with GA 26～27 weeks (2.0％, 5/247) (χ2=16.057, P<0.001). The incidence of SIP in infants with BW 400～749 g was 13.0％(14/108), which is higher than infants with BW 750～999 g (3.4％, 8/236) (χ2=11.343, P=0.001). Multivariate Logistic regression analysis showed that twins (OR=4.153, 95％CI 1.392～12.384, P=0.011), umbilical veins catheterization (OR=15.942, 95％CI 1.026～247.789, P=0.048) and ibuprofen use within 3 days after birth (OR=15.387, 95％CI 1.519～155.883, P=0.021) were independent risk factors of SIP. Conclusion The smaller the GA and BW, the higher the incidence of SIP. Twins,umbilical veins catheterization and ibuprofen use early after birth may be independent risk factors of SIP.

ABSTRACT
Objective To construct the Markov models to reflect the reality of prevention and treatment interventions against hepatitis B virus (HBV) infection,simulate the natural history of HBV infection in different age groups and provide evidence for the economics evaluations of hepatitis B vaccination and population-based antiviral treatment in China.Methods According to the theory and techniques of Markov chain,the Markov models of Chinese HBV epidemic were developed based on the national data and related literature both at home and abroad,including the settings of Markov model states,allowable transitions and initial and transition probabilities.The model construction,operation and verification were conducted by using software TreeAge Pro 2015.Results Several types of Markov models were constructed to describe the disease progression of HBV infection in neonatal period,perinatal period or adulthood,the progression of chronic hepatitis B after antiviral therapy,hepatitis B prevention and control in adults,chronic hepatitis B antiviral treatment and the natural progression of chronic hepatitis B in general population.The model for the newborn was fundamental which included ten states,i.e.susceptiblity to HBV,HBsAg clearance,immune tolerance,immune clearance,low replication,HBeAg negative CHB,compensated cirrhosis,decompensated cirrhosis,hepatocellular carcinoma (HCC) and death.The susceptible state to HBV was excluded in the perinatal period model,and the immune tolerance state was excluded in the adulthood model.The model for general population only included two states,survive and death.Among the 5 types of models,there were 9 initial states assigned with initial probabilities,and 27 states for transition probabilities.The results of model verifications showed that the probability curves were basically consistent with the situation of HBV epidemic in China.Conclusion The Markov models developed can be used in economics evaluation of hepatitis B vaccination and treatment for the elimination of HBV infection in China though the structures and parameters in the model have uncertainty with dynamic natures.

ABSTRACT
Background and purpose:Cancer is a major public health issue in China and worldwide, which se-riously threatens human beings as well as social and economic development. This study explored the relationships between the cancer distribution characteristics and cancer prevalences in Chinese cancer surveillance regions to provide scientific evidence for cancer prevention and management.Methods:The data were obtained from the book named“Prevalence and Mortality of Cancer in China from 2003-2007” including incidence of 23 cancer types in 32 regions of China published by the Academy of Military Medical Sciences of the Chinese PLA in 2012. Correspondence analysis was used to gain the relation between the prevalence and area distribution. Cluster analysis was used to obtain the classifications with special significance by putting the cancers or regions with similar characteristics into a cluster.Results:Esophageal cancer, gastric cancer, liver cancer, lung cancer, colorectal and anal cancer have high incidence and mortality in both genders. The districts with high incidence of esophageal cancer and gastric cancer were grouped together. The counties or cities (Shexian, Yangcheng, Linzhou, Yanting, Yangzhong and Jianhu) with high incidence of esophageal cancer and gastric cancer were classified into same cluster frequently. Fusui was grouped along because of the lower incidence of various cancers than the national average except for liver cancer. Guangzhou, Sihui and Zhongshan were the districts with high incidence of nasopharyngeal carcinoma in both genders. Rural areas in Qidong and Haimen were classified into a cluster in male and total data for the high incidence of liver cancer. Colorectal cancer, anal cancer and breast cancer in women also had high incidence in urban areas. Cervical cancer had the second level high incidence in women following diseases of digestive system, breast cancer and lung cancer.Conclusion:Similar pathogenic factors may exist in counties or cities of Shexian, Cixian, Yangcheng,etc, because of the high prevalence of esophageal cancer. Similar pathogenic factors may also exist in other districts or cancers that were classified into the same cluster.
ABSTRACT
Objective To explore the association between the CpG methylation level of positive regulatory domain containing 16(PRDM16)gene promoter and obesity or body mass index(BMI). Methods A total of 116 patients(91 female adults and 25 male adults) with abdominal operation in a municipal hospital of Henan province were enrolled in this study and they were divided into two groups:normal weight group(n=50), overweight or obesity group ( n=66 ) . Fasting plasma glucose, total cholesterol, triglyceride, high density lipoprotein and low density lipoprotein were measured in peripheral blood. DNA was extracted from white blood cells in peripheral blood and modified by bisulphite. Then the CpG methylation level of PRDM16 gene promoter was detected by mass spectrometry. Finally, all data were analyzed by IBM SPSS Statistics 21. 0 at the 5% level. The essential features and biochemical indexes of research objects between two groups were compared by two independent sample t-test, except chi-square test for gender. The correlation between CpG methylation level of PRDM16 gene and BMI was analyzed by multiple linear regression. Results There were no significant differences ( P>0. 05 ) in the methylation levels of PRDM16 gene's effective CpG sites(including CpG5. 6, CpG8, CpG9, CpG12, CpG13. 14. 15, CpG26. 27, CpG28 and CpG29) between two groups. The methylation level of CpG26. 27 had positive linear relation with BMI in overweight or obesity group with the standardized coefficients of 46. 928(P=0. 015), which means the higher the methylation level is, the higher the BMI would be. Conclusion The CpG26. 27 methylation level of PRDM16 gene promoter region may have relationship with the risk of obesity.
ABSTRACT
Objective To Study the effect of efflux pump-inhibitors(EPI)-Verapamil in photodynamic therapy (PDT) using hematoporphyrin monomethylether (HMME) as photosensitizer on the cariogenic bacteria in dental plaque biofilms.Methods According to the administrator order of the verapamil and photosensitizer in PDT,streptococcus mutans,streptococcus sanguis,eosinophilic lactobacillus and actinomyces viscosus were used to establish the dental plaque biofilm model.The experiment was divided into five groups,group A was incubated with the photosensitizer and verapamil group,group B using verapamil before incubated the photosensitize,group C suing photosensitizer before incubated verapamil,group D with PDT only,group E was control group.After laser treatment,the influence of the dental plaque biofilms was observed by confocal laser scanning microscope.Results As saline-treated group is a group of normal the dental plaque biofilms.In PDT only group,compared with the saline group,red fluorescence increased significantly,the bacteria lose accumulation capacity,and were isolated and scattered in dispersed state.In PDT plus verapamil group,compared with only PDT group,green staining increased,bacterial activity increased.In group B,cells were incubated with verapamil before incubated the photosensitizer group,green staining increased significantly,red fluorescence reduced,indicating live bacteria increased,and bacteria activity was significantly increased.Conclusion PDT is an effective method in eliminating cariogenic bacteria of dental plaque biofilms.Bacterial efflux pump inhibitors can lower HMME-PDT inhibition cariogenic bacteria in dental plaque biofilm,and pre-verapamil administration could significantly inhibit the effect of PDT treatment of dental caries.
ABSTRACT
Objective The purpose of this study was to assess the antibacterial effects of hematoporphyrin monomethylether-photodynamic therapy (HMME-PDT) on Enterococcus faecalis within infected simulated lateral canals in vitro with different energy.Methods Simulated lateral canals were prepared on extracted teeth.The specimens were infected with Enterococcus faecalis and then were randomly divided into eight groups.Group A was considered as negative control,its specimens were irrigated with physiological saline.Group B was the positive control,they were irrigated with 5.25％ NaClO.Other groups were incubated with HMME at concentration of 40 μg/ml for 5 min,followed by exposure to light at 532 nm for 120 s with different powers in a spiral pattern.Groups were named C-H,in corresponding with the power 50,60,70,80,90,100 mW.Microbial samples (the dentin chips from simulated lateral canals) were taken before and after the treatments.The survival fractions in each simulated lateral canal was calculated by counting colony-forming units(CFUs).Results 1.The HMME-PDT-treated groups resulted in a significant reduction in the number of E.faecalis in simulated lateral canals compared with the negative controls(P＜0.05).2.The antibacterial effects of group D、E、F、G、H were higher than the NaCl0-irrigated group(P＜0.05).3.The difference of antibacterial effects between the F、G、H groups was in significant(P＞0.05).Conclusion HMME-PDT had significant inhibitive efficacy on Enterococcus faecalis within infected simulated lateral canals and the efficacy was power-depended.It can play the best effect with the power of 80 mW.
