Objective To evaluate the efficacy and safety of butyl flufenamate ointment for the treatment of solar dermatitis.Methods Sixty-four patients with solar dermatitis were randomly divided into the observation group (n =32) and control group (n =32) to topically apply butyl flufenamate ointment and diclofenac sodium cream,respectively,for 3 weeks.The efficacy was evaluated by lesion scores and a visual analog scale for pruritus.Results At the end of the treatment,4 patients in the observation group were clinically cured,19 markedly improved,17 improved,and 2 showed no improvement; meanwhile,2 patients in the control group were clinically cured,11 markedly improved,14 improved,and 5 showed no improvement.The total response rate was significantly higher (93.8％ vs.84.4％,P ＜ 0.05),while the pruritus score was significantly lower (P ＜ 0.05) in the observation group than in the control group.Conclusion Butyl flufenamate ointment is superior to dicofenac sodium cream in terms of both efficacy and anti-pruritic effect.

Objective To discuss effects of Wugong Baidu Drink on expressions of Bcl-2, NF-κB mRNA genes related to the apoptosis of HaCaT in psoriasis. Methods Wistar rats were randomly divided into 6 groups:blank group, Western medicine control group, TCM control group, and Wugong Baidu Drink high, medium, and low dose groups. They were given normal saline, methotrexate suspension, compound natural indigo capsule suspension, and the different doses of Wugong Baidu Drink for gavage, respectively. Drug-containing serum of each group was prepared, and was put in the HaCaT respectively to subculture. The intervention effect of different Drug-containing serums on expressions of objective genes were detected through PR-PCR method. Results Drug-containing serum of each group could decrease the expressions of Bcl-2 mRNA and NF-κB mRNA. The most obvious effects were shown in the groups of Western medicine control group and Wugong Baidu Drink high dose group. All Wugong Baidu Drink groups showed a dose-response relationship. Conclusion Wugong Baidu Drink probably can promote the apoptosis of HaCaT by reducing the gene expressions of Bcl-2 and NF-κB. It can also decrease immune response by regulating serum factors related to T cells to play the role of anti-psoriasis.

Currently,the environment for establishing anesthesiologic undergraduate education no longer exists,and the side-effects of its narrow professional content are more and more apparent,so canceling undergraduate education of anesthesiology is becoming imperative.The education of anesthesia must be reformed.However,the direction of reform is not clear.Anesthesia long-term system education and Anesthesia and preoperative medical education are two optical reform directions with its own advantages and disadvantages.Comparing these two directions,the Anesthesia and preoperative medical education seems to be the better one.

BACKGROUND:Injection of isoproterenol is known to induce proliferation and hypertrophy of acinar cells in rodent salivary glands. However, the clonal proliferation ability of stem/progenitor cells of salivary glands by isoproterenol remains unclear.
OBJECTIVE:To study the proliferation and activation ability of stem/progenitor cells of submandibular gland with colony assay by intraperitoneal injection of isoproterenol.
METHODS:Sprague-Dawley rats were randomly divided into two groups, isoproterenol and control groups, respectively intraperitonal y injected with isoproterenol and normal saline for 5 consecutive days. The gland tissues were harvested, and the stem/progenitor cells of submandibular gland were obtained by enzyme digestion in vitro. The number of clonal colonies of each group was analyzed. The larger colony cells were col ected for immunohistochemistry staining with CD90.1, laminin andα6β1.
RESULTS AND CONCLUSION:The number of middle and low proliferative potential colony-forming cells was less but high proliferative potential colony forming cells were significantly more in isoproterenol group compared with control group (P<0.05). However, there was no significant difference in the total number of the colonies between two groups (P>0.05). The high proliferative potential colony forming cells were positive for CD90.1, laminin andα6β1. Results showed that isoproterenol treatment model cannot increase the cellnumber, but enhance the proliferation ability of stem/progenitor cells from the submandibular gland.

Objective To investigate the role of NF-κB activation in the inflammatory mechanism of chronic obstructive pulmonary disease (COPD).Methods Monocyte were collected from patients with COPD and were cultured,and stimulated with lipopolysaccharide (LPS) ; NF-κB p65 activation was measured by immunohistochemistry; SOD ,MDA and IL-8 and lung function were determined synchronously.Results The NF-κB p65 was induced by LPS in monocyte in all subjects, but it was most markedly done in COPD patients with exacerbateions; There was positive correlation between the NF-κB p65 activation of monocytes and levels of IL-8 and MDA in circulation, but it was negative correlation to SOD.Conclusion NF-κB plays a vital role in regulating product of IL-8 in monocyte in COPD.
