2.Advances in clinical study of postoperative radiotherapy and chemotherapy for patients with esophageal carcinoma
Journal of International Oncology 2010;37(12):919-921
Local recurrence and distant metastasis is the major factor of impacting long-term survival for patients with esophageal carcinoma after radical resection. Postoperative radiotherapy and chemotherapy is expected to reduce the rate of local recurrence and distant metastasis, but views for the value of postoperative radiochemotherapy were inconsistent in the past. In recent years, scholars have performed much more clinical studies on postoperative radiotherapy and chemotherapy and found that the combined postoperative radiotherapy and chemotherapy after surgery significantly reduces the recurrence rate and distant metastasis rate and can enhance the survival of the patients.

5.Comparison of two different drug therapies for acute retinal necrosis syndrome
International Eye Science 2016;16(7):1366-1368
AIM: To investigate clinical efficacy of two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin) for acute retinal necrosis syndrome.
METHODS: Thirty patients (40 eyes) with acute retinal necrosis syndrome in our hospital were randomly divided into group A and B. Group A was treated with acyclovir with prednisone acetate tablets, and group B was given ganciclovir with prednisone acetate tablets and aspirin. Clinical effects in the two groups were observed and compared.
RESULTS: After treatment, the overall response rate in group B (90%) was obviously higher than that in group A (70%), both of two regimens were effective, without significant difference (P>0. 05). There was no significant difference on the pre - treatment visual acuity between the two groups (P>0. 05). After different treatments, the visual acuity in group B was ≥0. 5 in 12 eyes, 0. 1≤and<0. 5 in 4 eyes, 0. 02 ≤ and < 0. 1 in 3 eyes, and no photosensitive in 1 eye. The visual acuity in group A was≥0. 5 in 9 eyes, 0. 1≤and<0. 5 in 3 eyes, 0. 02≤and<0. 1 in 6 eyes, and no photosensitive in 2 eyes. The recovery of visual acuity in group B was obviously better than that in A group ( P < 0. 05). The incidence of complications such as retinal tear, herpes, mouth ulcers, chickenpox, viral encephalitis and central nervous system diseases in group B (10%) was significantly lower than that in A group (35%,P<0. 05).
CONCLUSION: Two drug therapies ( acyclovir with prednisone acetate tablets, ganciclovir with prednisone acetate tablets and aspirin ) both have positive therapeutic effect, but the latter can better restore visual acuity and decrease the complications.
6.Artificial ossicular chain reconstruction:biocompatibility, properties and laryngecartilage defect repair
Chinese Journal of Tissue Engineering Research 2016;20(25):3713-3719
BACKGROUND: Defected Laryngeal cartilage has many alternatives, including autologous cartilage, al ograft cartilage and metal stents. Although these materials can achieve desired outcomes in laryngeal cartilage defect repair, certain limitations exist. OBJECTIVE: To investigate the biocompatibility and properties of artificial ossicular chain reconstruction materials, and to explore the effect of artificial ossicular chain reconstruction materials on laryngeal cartilage defect repair. METHODS: Porous hydroxyapatite otosteon was prepared by high-temperature calcination of hydroxyapatite, fol owed by cultured in bone morphogenetic protein solution extracted from fresh human bone to construct bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material. And then, the biocompatibility and characteristics of the material were analyzed. Forty adult male New Zealand white rabbits were randomly divided into porous hydroxyapatite group and artificial ossicular chain reconstruction material group (n=20 per group), and underwent repair with porous hydroxyapatite material and bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material respectively after modeling of laryngeal cartilage defect. RESULTS AND CONCLUSION: There was a significant difference in compressive strength of artificial ossicular chain reconstruction materials with different porosities. No symmetry sphere formed in hol ows of the outer surface of the material, with polygonal appearance and with a pore size of 100-200 μm. There were no obvious adverse reactions in both two groups after implantation, but in the artificial ossicular chain reconstruction material group, numerous fibrous connective tissues and obvious bone nodules appeared, and the degradation rate of the material was faster. These results suggest that the bone morphogenetic protein-hydroxyapatite artificial ossicular chain reconstruction material exhibits good biocompatibility and properties, which wil obtain satisfactory outcomes for laryngeal cartilage defect repair. So, the material holds a great value of clinical application.

O-linked N-acetylglucosamine (O-GlcNAc) glycosylation is an important form of posttranslational protein modification,mainly intracellular.It is closely related to cellular signaling pathways,and is involved in signal transduction,gene transcription and other important biological processes.Studies have found that O-GlcNAc glycosylation is directly related with diabetic retinopathy (DR),further studies may help us to uncover the DR mechanism,and develop new strategies for the diagnosis and treatment of this disease.

AIM: Tumor necrosis factor-?(TNF-?) participates in the establishment of inflammatory lesions in pneumonia.High production of TNF-? may relate to the severity of pneumonia.There have already been several studies examining the association between pneumonia and single nucleotide polymorphisms(SNPs) that affect cytokine productivity.SNPs of TNF-?,-1 031,-863,-857,-308 and-238 have been identified.The variant alleles of these SNPs have suggested to be related to high TNF-? production and the severity of pneumonia.Therefore,the aim of this study is to examine the association between the severity of pneumonia in Chinese and the following SNPs: five in the TNF-? gene promoter(-1 031,-863,-857,-308,-238).METHODS: A total of 117 Chinese individuals were enrolled in this study.They were 67 patients with pneumonia and 50 healthy subjects.TNF-? was genotyped by polymerase chain reaction-restriction fragment length polymorphism for all subjects.The frequency distributions of genotypes in different groups were analyzed by SPSS 11.5 program.RESULTS: Frequency of subjects who carried at least one variant allele in TNF-?-1 031,-863,-857,-308,-238 SNPs among pneumonia patients was significantly higher than that in healthy subjects.And frequency of subjects who carried variant allele in TNF-?-863,and-308 SNPs among severe adult community acquired pneumonia patients was significantly higher than that in common pneumonia patients.CONCLUSION: TNF-?-863 and-308 SNPs appear to be associated with severe adult community acquired pneumonia in Chinese populations.

Objective To investigate the effects of oxymatrine on liver fibrosis and its mechanism. Methods The rat model of liver fibrosis induced by CCl 4 was set up. The effect of oxymatrine anti-liver fibrosis were evaluated by comparing liver weight index, serum/tissue biochemical indices and the change of tissue pathology before and after oxymatrine intervention. The levels of serum HA,PⅢP,LN and Ⅳ-C were also measured before and after oxymatrine treatment. Results In CCL4-induced liver fibrosis model rats, the levels of serum HA,PⅢP,LN and Ⅳ-C significantly decreased(P
