Objective: To investigate the characteristics of peripheral circulating lymphocyte subsets in severe hepatitis patients with chronic HBV infection (SHPCHI). Methods: The numbers of circulating lymphocyte subsets, including CD3+, CD4+ and CD8+, NK cells (CD3- /CD16+ /CD56+), and NKT cells (CD3+ /CD16+ CD56+), were determined in SHPCHI (n=61),patients with chronic hepatitis B (CHB, n=21), patients with cirrhosis (LC, n=26) and healthy volunteers (n=10) by flow cytometry. The absolute values of each lymphocyte subset were calculated and statistically analyzed. Results: The absolute numbers of circulating CD3+, CD4+ and CD8+ T cells were significantly reduced in SHPCHI group compared with those in the other 3 groups (P<0.01 or P<0.05). There was a decreasing trend in the absolute numbers of peripheral CD3+, CD4+, CD8+ and NK cells in non-surviving SHPCHI compared with surviving SHPCHI,but the decrease was not statistically significant. Conclusion: SHPCHI has an disorderd cellular immune function, which might be related to the prognosis of SHPCHI.

Objective To study the influence of HBV replication regulator,enhancer I and Pre- S2,on the immune response of HBV DNA vaccine.Methods DNA fragments of HBsAg,PreS2 HBsAg,HBsAg-enhancer I and PreS2-HBsAg-enhancer I region of HBV were amplified by PCR using the complete genome DNA of HBV adr subtype,and inserted into VR1012 vectors,respective- ly.The recombinant plasmids were transfected into HepG2 cells,and injected into Balb/C mice.The expression of HepG2 cells and the cellular and humoral immune response of mice were tested by cell immuno-chemistry,ELISA and ELISPOT.Results The target protein were expressed by transfected HepG2 cells,enhancer I and Pre-S2 can promote the expression of HBsAg in transfected cells.The HBsAb and the HBsAg specific CTL in inoculated mice were found in the second week after injection, PreS2 but not enhancer I can promote the immune response in inoculated mice.Conclusions When inserted into HBV DNA vaccine,enhancer I and PreS2 can promote the expression of HBsAg in transfected HepG2 cells,PreS2 can promote the immune response in inoculated Balb/C mice.

As the number of patients with compromised immune function increases and fungal resistance develops, so does the risk of contracting deadly fungi in humans. Both fungi and humans are eukaryotes, so identifying unique targets for antifungal drug development is difficult. In addition, the existing antifungal drugs are limited by toxicity, drug interaction and drug resistance in practical application, which leads to the increasing incidence and fatal rate of fungal infections. Therefore, it is urgent to develop new antifungal drugs. The semi-synthetic technology using microbial fermentation products from natural sources as lead compounds has become the most used method in structural modification of antifungal drugs due to its advantages of few reaction steps and easy operation. This paper will introduce the current status of natural antifungal drugs in clinical use, as well as the latest progress in the research and development of new semi-synthetic antifungal drugs, and summarize their mechanism of action, structural modifications, advantages and disadvantages, so as to provide reference for the subsequent development of new antifungal drugs.

AlM:To observe the changes of corneal endothelium after phacoemulsification cataract surgery in different types of cataract patients.
METHODS: Randomly selected age-related cataract, diabetic cataract and cataract of high myopia 30 eyes of 30 cases, respectively, in our hospital. All patients underwent phacoemulsification combined with intraocular lens implantation, corneal endothelial density and the percentage of hexagonal cells were measured by corneal endothelial cell instrument without touching before surgery and one week after surgery.
RESULTS: The difference of the preoperative corneal endothelial cell density and the percentage of hexagonal cells among three groups were not statistically significant (P>0. 05). One week after surgery, the cell density in three groups were respectively 2 496. 86 ± 298. 96/mm2 , 2 379. 51 ± 375. 13/mm2 , 2 425. 38 ± 312. 68/mm2 , the percentage of hexagonal cells were respectively ( 46. 20 ± 12. 03)%, (43. 44±13. 99)%, (44. 35±8. 13)%. Both the cell density and the percentage of hexagonal cells one week after surgery were lower than those before operation. There were significant difference in three groups ( P <0. 05). Both the measurements in diabetic cataract group and cataract of high myopia group after surgery were lower than those in age-related cataract group, the cell density and the percentage of hexagonal cells in diabetic cataract group were lower obviously compared with those in age- related cataract group and the difference was significant (P<0. 05).
CONCLUSlON:The tolerance of corneal endothelial cell to phacoemulsification cataract surgery is lower in cataract with diabetes and high myopia. Corneal endothelium should be assessed preoperatively and protected intraoperatively.
