AIM: To observe the effect of combined goniosynechialysis in treating absolute glaucoma after trabeculectomy.
METHODS:Phacoemulsification combined goniosynechialysis was performed on 16 patients ( 16 eyes ) with absolute glaucoma after trabeculectomy, and they were followed up for 6 ~12mo, The postoperative intraocular pressure ( IOP ) and anterior chamber depth, preoperative and postoperative medication types (quantity), preoperative and postoperative 1 month's status of anxiety and depression, symptoms of ocular surface were observed. RESULTS: The IOP decreased significantly after phacoemulsification combined goniosynechialysis. The mean IOP was 35. 00±15. 43mmHg preoperatively, and it was 12. 00±6. 69mmHg, 15. 00±4. 26mmHg and 15. 3±5.2mmHg on 1d, 6 and 12mo after the surgery. The statistic difference was found between preoperative and postoperative (t=6. 22, P<0. 05). The anterior chamber depth was 1. 45 ± 0. 19mm before the surgery, and increased to 3. 37±0. 13mm after the surgery (t=6. 65, P<0. 05). After the surgery, 2 patients needed two kinds of drugs, 2 patients needed one kind of drug. After 12mo of follow-up, anxiety and depression status were improved in all 16 patients. Subjective discomfort symptoms of 16 patients such as eye bilges, eye pain were relieved. All of the patients' eyeballs were preserved, and no serious complications.
CONCLUSION: Phacoemulsification combined goniosynechialysis in treating absolute glaucoma after trabeculectomy is a safe and effective surgical option.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.

Objective To investigate the effects of in vivo electroporation on plasmid mediated reporter gene expression and immunogenicity of DNA vaccine. Methods Luciferase expression plasmid was administered intramuscularly to BALB/c mice at 8μg and 40μg dosage level through injection with or without eletroporation Luciferase expression level in murine muscle was detected by IVIS imaging system 24 h after injection. DNA vaccine plasmid p1.0-gp1455m carrying codon-optimized env gene of CN54 strain ( HIV-1 CRF07_BC) was administered to mice at dosages of 8μg and 40μg through the two approaches mentioned above. Mice were immunized at week 0,2 and 4. Env-specific immune responses were detected at two weeks post the second and the third vaccinations. Env-specific antibody immune responses were determined by ELISA. Euv-specific cellular immune responses were determined by IFN-γ ELISPOT. Results Luciferase expression level in murine muscle was significantly increased as much as 35 folds through in vivo eletroporation. Results of ELISA and ELISPOT revealed that in vivo eletroporation could significantly enhance both the humoral and cellular immune responses induced by DNA vaccination. The responses induced by electrodelivered p1.0-gp1455m at 8 μg dosage were better than those induced by simple intramuscular injection with 40 μg of plasmid DNA. On the other hand, 2 injections followed by electroporation elicited comparable level of humoral and cellular immune responses with those induced by 3 injections without electroporation. Conclusion In vivo electroporation was capable of enhancing both the plasmid-mediated gene expression and immunogenicity of DNA vaccine.

Objective To assess and compare the difference in image quality and exposure dose between single-sided reading image plate(IP)and dual-sided reading IP.Methods A contrast-detail phantom CDRAD 2.0 was exposed by single-sided and dual-sided reading IP with different mAs sets.The entrance surface doses were recorded for all images.Images were then presented to two radiologists on a high resolution monitor of diagnosis workstation.The image quality figure(IQF)was measured for each image. Statistical analysis was performed using Spearman's correlation test and Wilcoxon signed-rank test to compare the difference in image quality and exposure dose between single-sided IP and dual-sided reading IP. Results With different tube current dosage of 5.6,12.0,20.0,25.0,and 40.0 mAs,IQF values of single-sided reading IP were 47.95,37.68,34.31,28.61,and 24.65,respectively,while those of dual- sided reading IP were 38.83,29.81,29.65,25.16,and 21.43,respectively.The IQF difference between them showed statistical significance(P

The use of monoclonal antibodies (mAbs) for cancer therapy has achieved considerable success in recent years. Approximate 17 monoclonal antibodies have been approved as cancer therapeutics since 1997. Antibody-drug conjugates (ADC) are powerful new treatment options for cancer, and naked antibodies have recently achieved remarkable success. The safety and effectiveness of therapeutic mAbs in oncology vary depending on the nature of the target antigen and the mechanisms of tumor cell killing. This review provides a summary of the current state of antibody-based cancer therapy, including the mechanisms of tumor cell killing by antibodies, tumor antigens as antibody targets, clinical effectiveness of antibodies in cancer patients and nanoparticles-based ADCs.

OBJECTIVETo evaluate the roles of N-terminal lectin-like domain of thrombomodulin (TM-N) and receptor for advanced glycation end products (RAGE) in acute hepatic failure using a mouse model system.

METHODSAcute hepatic failure was induced in Kunming mice by intraperitoneal injection of D-galactosamine (D-Galn at 600 mg/kg) and lipopolysaccharide (LPS at 5 mug/kg) and mice were divided into groups for injection with saline, recombinant (r)TM-N protein, or recombinant soluble (rs)RAGE protein. Unmanipulated model mice served as the negative controls. Effects on liver expression of high mobility group box-1 (HMGB1) were detected by immunohistochemistry and real time RT-PCR. Effects on serum levels of tumor necrosis factor-alpha (TNFa) and interleukin-1 beta (IL)-1b were quantified by ELISA.

RESULTSTreatment with rTM-N and rsRAGE both alleviated the acute liver damage induced by D-Galn/LPS exposure, and decreased the hepatic expression of HMGB1 as well as the serum levels of TNFa and IL-1b.

CONCLUSIONIntraperitoneal delivery of rTM-N and rsRAGE can alleviate acute liver damage by modulating the expression of necrosis- and inflammation-related factors.
