AlM: To explore the clinical significances and changes of related parameters of corneal endothelial cell in keratouveitis patients before and after treatment.
METHODS:Fifty-two keratouveitis patients ( 52 eyes ) diagnosed and treated in our hospital from October 2012 to December 2013 were collected. Before and after treatment, the related parameters of corneal endothelial cell in all patients were measured with non - contact corneal specular microscope and these parameters were statistically analyzed.
RESULTS: Compared with the normal group, obvious endothelial cell edema and great variation was observed in diseased group. The shorter duration of treatment, the better the recovery of endothelial cells and the fewer cells lose. Conversely, the longer the healing of normal hexagonal cell ratio was smaller, the larger the coefficient of variation. Before and after treatment, the differences of each parameter were statistical significance (P<0. 05).
CONCLUSlON: The functional recovery of corneal endothelial cell has directly relation with disease times.

[Objective]To analyze the clinical and pathological characteristics of myoepithelial carcinoma of nasopharynx,as well as its relationship with Epstein-Barr virus.[Methods]We report twelve cases of myoepithelial carcinoma of nasopharynx,study its clinical,histopathologic,and immunohistologic features,follow-up data and EBERS in-situ hybridization.[Results]Among age of patients ranged from 24 to 65 years(mean age=46 years).Imagery data demonstrated an extensive nodosity filling the nasopharynx,Of these 12 cgses,myoepithelial markers such as S-100,SMA,P63,CK14,CK5/6 and epithelial markers such as CK,CKL,CKH were not always all expressed at one case,but at less one of these two kind of markers expressed at one cage.The results of EBERS in-situ hybridization of 12 cases were negative.[Conclusion]Myoepithelial carcinoma is a low malignat tumor.It seldom takes place in nasopharynx,dispite its morphologic heterogeneity it has some special morphologic and immuohistologic characteristics as well as special result of EBERS in-situ hybridization,which may support its diagnosis.The combinde radiotherapy and chemotherapy after surgical removal of the tumor will control the recurrence and metabasis effectively.

AIM: To investigate the action of testosterone on atherosclerosis in a rabbit model. METHODS: 37 male cholesterol-fed rabbits were divided into five groups: castration group: castrated rabbits without exogenous testosterone administration; testosterone Ⅰ group: castrated rabbits with exogenous testosterone 0.25 mg?kg -1?d -1; testosterone Ⅱ group: castrated rabbits with exogenous testosterone 2.5 mg?kg -1?d -1; testosterone Ⅲ group: castrated rabbits with exogenous testosterone 12.5 mg?kg -1?d -1. The sham operation group was also set. Three months later, the levels of testosterone, blood lipids (including TG, HDL-C, LDL-C), PAI activity, nitric oxide (NO) content, endothelin (ET), angiotensin Ⅱ (AngⅡ) in blood were detected. RESULTS: It showed that testosterone in castration group was the lowest. There was no significant difference of TG or LDL-C between castration group and the other four groups. HDL-C in castration group was lower than that in other four groups. NO content of castration group was lower than that in others, but PAI activity, ET and AngⅡ concentration were higher than that in other groups. CONCLUSION: Testosterone is a protective factor against atherosclerosis in male rabbits.

ObjectiveTo compare the therapeutic efficacies between acupoint thread embedding plus Western medication and dry Western medication in treating metabolic syndrome.MethodTotally 320 patients with metabolic syndrome were randomized into a treatment group and a control group, 160 cases in each group. The control group was intervened by ordinary Western medication, while the treatment group was by acupoint thread embedding in addition to the Western medication given to the control group, and Yishu (Extra), Geshu (BL17), Ganshu (BL18), Pishu (BL20), Shenshu (BL23), Tianshu (ST25), Daimai (GB26), and Guanyuan (CV4) were selected as the major points. The therapeutic efficacies, metabolism-related parameters, liver function, and kidney function were compared between the two groups, and the therapeutic efficacies of different syndromes were also compared.ResultThe markedly effective rate and total effectiverate of the treatment group were significantly higher than that of the control group (P<0.01). After treatment, there was no significant difference in comparing the HDL-C between the two groups (P>0.05), but there were significant inter-group differences in comparing the rest parameters including liver and kidney functions (P<0.05), and the treatment group was superior to the control group. Acupoint thread embedding produced a more significant efficacy in treating metabolic syndrome due to heat in liver-stomach and phlegm-dampness stagnancy compared to the control group (P<0.05), and the efficacy of acupoint thread embedding in treating metabolic syndrome due to phlegm-dampness stagnancy was significantly different from that of the control group (P<0.01).ConclusionAcupoint thread embedding plus Western medication can produce a more significant therapeutic efficacy in treating metabolic syndrome compared to Western medication alone, and it’s safe; of all the patterns, phlegm-dampness stagnancy responds thebest to acupoint thread embedding.

Objective:To explore the effect of venetoclax-based therapy on relapsed/refractory multiple myeloma (MM) patients harboring t(11;14).Methods:The data of a relapsed/refractory MM patient harboring t(11;14) treated with venetoclax-based regimen admitted to Shanghai Changzheng Hospital in June 2019 was retrospectively analyzed and the literatures were reviewed.Results:The relapsed/refractory MM patient harboring t(11;14) had progression of disease after 3 lines of therapies, and then was treated with the selective bcl-2 inhibitor venetoclax combined with daratumumab and dexamethasone. As a result, the patient achieved partial remission and better hemogram recovery. The Eastern Cooperative Oncology Group (ECOG) score of physical status decreased from 3 to 1, and the quality of life was improved significantly.Conclusions:The relapsed/refractory MM patients harboring t(11;14) could benefit from venetoclax-based therapy. In the future, the safety, sensitivity and other performances of venetoclax in the treatment of MM should be further explored.

Objective:To study effects of large dose thymopeptides on T cell subpopulations of patients with malignant tumor under radiotherapy.Methods:Fifty one patients with malignant tumor under radiotherapy were divided into 2 groups with 100 mg and 200 mg thymopeptides respectively.The patients we re given thymopeptides,100 mg/d or 200 mg/d,iv, for 10 days.The positive percent ages of CD4,CD8,CD25 and CD56 in T cells of peripheral blood before and after thymopeptide treatment were determined by flow cytometry.Results:The positive percentages of CD4 and CD25 in T cells of peripheral bl ood after 100 mg/d thymopeptide treatment were significantly higher than those befor e thymopeptide treatment (P<0.05),while those of CD4，CD8，CD25 and CD56 in T cells of peripheral blood after 200 mg/d thymopeptide treatment all increased significantly (P<0.05 or P<0.01). Conclusion:These results suggest that large dose of thymopeptides can increase i mmune function of patients with malignant tumor under radiotherapy,and the curat ive effect of 200 mg/d thymopeptides is better.

Conclusion Chongqing wild Fritillaria taipaiensis resources are wide distributed and with long history of medical usage. Chongqing is the original producing area of Fritillaria taipaiensis, which has been destroyed by human factors. Fritillaria taipaiensis resources in several districts have become extinct, however, the cultivated Fritillaria taipaiensis resources is developing rapidly.

Based on the transcriptome data, we cloned the open reading frame of IiHCT gene from Isatis indigotica, and then performed bioinformatic analysis of the sequence. Further, we detected expression pattern in specific organs and hairy roots treated methyl jasmonate( MeJA) by RT-PCR. The IiHCT gene contains a 1 290 bp open reading frame( ORF) encoding a polypeptide of 430 amino acids. The predicted isoelectric point( pI) was 5.7, a calculated molecular weight was about 47.68 kDa. IiHCT was mainly expressed in stem and undetectable in young root, leaf and flower bud. After the treatment of MeJA, the relative expression level of IiHCT increased rapidly. The expression level of IiHCT was the highest at 4 h and maintained two fold to control during 24 h. In this study, cloning of IiHCT laid the foundation for illustrating the biosynthesis mechanism of phenylpropanoids in I. indigotica.
