Objective To observe the effect of the aloe juice reducing skin injury of face and neck caused by radiotherapy in nasopharyngeal cancer patients. Methods Eighty nasopharyngeal cancer patients admitted in hospital from March 2007 to January 2009 were randomly recruited into a control group and a treatment group. The treatment group (n=48) was treated by smearing on face and neck skin with aloe juice after the conventional fractionation radiotherapy. The control group (n=32) received no therapeutic measures after the conventional fractionation radiotherapy. Results In the treatment group there were 21 patients and 13 patients had I degree and II degree of skin lesion respectively; and in the control group, there were 5 patients and 10 patients had the I degree and II degree of skin lesion respectively. There was a significant difference between the two groups (χ~2= 10.6. P<0.05). Conclusion Aloe juice can reduce the injury of skin caused by radiotherapy.

BACKGROUND:Hepatocyte transplantation has attracted more and more attention as a therapeutic measure for liver failure and genetic metabolic liver diseases.OBJECTIVE:TO evaluate the efficacy and safety of human hepatocyte transplantation in treating hepatitis B related liver failure in one case by a 2-year follow-up.DESIGN:A case-report of 2-year follow-up.SETTING:No.9 Department of Infectious Diseases,Bioengineering Research Room,the 302 Hospital of Chinese PLA.PARTICI PANT:One inpatient with hepatitis B related liver failure was selected from the 302 Hospital of Chinese PLA.and she was diagnosed according the laboratory tests.The transplanted hepatocytes were originated frOm the healthy liver of a 24-year-old man,who had signed the protocol for liver donation before death.METHODS:The hepatocyte transplantation was completed in the Department of Radiology,the 302 Hospital of Chinese PLA in December 2004.Liver was isolated to obtain human primary hepatocytes, and then cryopreserved.The hepatocytes were transplanted into recipient spleen via femoral vein after resuscitation.The clinical symptoms,changes of blood biochemical indexes,and changes of spleen MRI signals were observed before and after operation.The patient was reexamined every half a year after operation, including liver function, blood coagulation function,B-mode ultrasonography,gastroscopy and MRI,and she was followed up for 2 years. MAIN OUTCOME MEASURES:Liver function,blood coagulation function, imaging indexes, immunological indexes,complication and rejection.RESULTS:①Totally(1-2)×1010 hepatocytes were harvested,and the viability of rewarmed hepatocytes was 60%,and finally 2×109 hepatocytes were transplanted.②Two months later,the clinical symptoms of the recipient were obviously ameliorated,and serum bilirubin and aspartate aminotransferase(AST)were obviously decreased,while prothrombin activity was markedly increased.20 months later,the MRI results showed that there was hepatocyte image in spleen.Two years after operation.the total bilirubin level was 20 μmol/L,direct bilirubin level was 7 μmol/L, alanine aminotransferase was 416.75 nkat/L,AST was 533.44 nkat/L,albumin was 37 g/L,prothrombin activity was 90%,which were all obviously ameliorated as compared with those before operation(474.5 μmol/L,340.3 μmol/L,400.08 nkat/L,1 200.24 nkat/L,38 g/L,25%).The patient left the hospital 2 months later and could do light-burdened job.No complications of hydroperitonia and liver function failure, etc.were observed,and no rejection occurred.Several reexaminations by B-mode ultrasonography all indicated the further aggravations of liver cirrhosis and esophageal varices.She was admitted to hospital for twice because of esophageal varices bleeding,and cured by endoscopic variceal sclerosis therapy.CONCLUSION:Hepatocyte transplantation can ameliorate liver function without rejection,but it cannot relieve portal hypertension.

Objective:To investigate therapeutic effect of cisplatin sequential recombinant human vascular endostatin thoracic perfusion in treatment of malignant pleural effusion.Methods:A total of 80 patients with malignant pleural effusion in Maoming People's Hospital from January 2018 to February 2021 were enrolled, and all patients were divided into 2 groups according to the random number table methods, each group with 40 cases. The control group was treated with small-bore catheter minimally invasive drainage combined with cisplatin thoracic perfusion, and the study group was treated with small-bore catheter minimally invasive drainage combined with cisplatin sequential recombinant human vascular endostatin thoracic perfusion. And then the clinical efficacy, expressions of vascular endothelial growth factor (VEGF) expression, pain degree and adverse reactions were compared of both groups.Results:The treatment efficacy rate of the study group was higher than that of the control group [90% (36/40) vs. 75% (30/40)], and the difference was statistically significant ( χ2 = 5.04, P < 0.05). After treatment, the level of VEGF in pleural fluid and serum of the study group was lower than that of the control group [(304±106) pg/ml vs. (598±159) pg/ml,(103±43) pg/ml vs. (189±49) pg/ml], and the difference was statistically significant ( t = 6.62, P < 0.001; t = 6.23, P < 0.001). After treatment, the visual analogue scale (VAS) score of the study group was lower than that of the control group [(3.7±0.3) scores vs. (4.4±0.7) scores], and the difference was statistically significant ( t = 2.10, P < 0.05). The incidence of adverse reactions including stethalgia, fever, nausea and vomiting in both groups had no statistically significant differences (all P > 0.05). Conclusions:Cisplatin sequential recombinant human vascular endostatin thoracic perfusion combined with small-bore catheter minimally invasive drainage can effectively ameliorate clinical symptoms, inhibit the expression of VEGF, and alleviate pain degree with no serious adverse reactions in patients with malignant pleural effusion.

Objective To screen key genes and pathways of acute on-chronic liver failure(ACLF)by multiple bioinformatics,and to provide theoretical basis for molecular biology studies and biomarker screening of ACLF.Methods ACLF transcriptome mRNA mi-croarray data set was downloaded from Gene Expression Omnibus(GEO),and limma package in R software was used to analyze the difference expression genes.The gene ontology(GO)function enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG)anal-ysis were analyzed differential genes through David database.Protein-protein interaction(PPI)network was analyzed using STRING da-tabase,the key differential genes were screened by Cytoscape software.Results A total of 329differentially expressed genes were screened,including 185 up-regulated genes and 144 down-regulated genes.GO functional enrichment analysis obtained 385 items,in-cluding immune receptor activity,cytokine receptor activity,T cell receptor binding and other biological functions(P<0.05).KEGG pathway enrichment analysis screened 36signaling pathways,among which the immune and inflammatory pathways including Th1 and Th2 cell differentiation,Th17 cell differentiation pathway,T cell receptor signaling pathway,primary immune deficiency,NF-κB signaling pathway and TNF signaling pathway.Among these key genes,CD3G,CD3D,IL7R,LCK,IL1R2,IL18R1,IL1R1 and MAPK14 related to ACLF were further obtained,which may become potential biomarkers and therapeutic targets of ACLF.Conclusion This study demon-strates that CD3G,CD3D,IL7R,LCK,IL1R2,IL18R1,IL1R1 and MAPK14may become the core genes related to the occurrence and development of ACLF and new therapeutic targets in the future.
