Chinese Journal of Clinical Pharmacology and Therapeutics 2004;0(12):-
AIM: To observe the effect of phagotrophic ability of macrophage on pseudomonas aeruginosa which was cocultured with low concentration of erythromycin. METHODS: The pseudomonas aeruginosa ATCC 27853 was cultured in LB both with low concentration of erythromycin (Group A) and without erythromycin (Group B) for 18 h separately, then incubated with macrophage from murine abdominal cavity for 2 h. The ratio of phagocytosis of macrophage was determined by microscope detection. RESULTS: The ratio of phagocytosis of group A in which erythromycin was added was higher than the group B, and the pseudopodia of macrophage were increased in the group A under electron microscope. CONCLUSION: Low concentration of erythromycin may enhance the phagocytosis ability of macrophage in vitro by influencing the virulent factors of PA.

International Eye Science 2015;(7):1220-1222
AlM:To explore the efficacy and safety of mitomycin C used in trabeculectomy by analyzing intraocular pressure and blood flow.METHODS:A total of 103 patients with glaucoma were divided into 2 groups randomly, and all patients were treated with trabeculectomy, while patients in the observation group were given mitomycin C extra. At 6~12mo follow-up were completed after operation, and the clinical efficacy, complications and hemodynamic characteristics of central retinal artery were compared between groups.RESULTS: The clinical efficacy of the observation group was higher than that of the controls (P<0. 05). There was no significant difference in complication rate between groups (P>0. 05), but the complication type was differentiate to some extent. Low intraocular pressure and photophobia symptoms occurred mostly in the observation group, while cicatricial obstruction occurred mostly in the controls. Before treatment, there was no significant difference in hemodynamic characteristics between groups (P>0. 05). One month after treatment, the peak systolic velocity ( PSV) and end diastolic velocity ( EDV ) of the observation group were obviously lower, while resistance index ( Rl ) and pulsatility index ( Pl ) were higher than those of the controls, the difference was statistically significant ( P<0. 05). Six months after treatment, the PSV and EDV of the observation group were obviously higher, while Rl and Pl were lower than those of the controls, the difference was statistically significant (P<0. 05).CONCLUSlON:Mitomycin C has a short-term harmful effect on glaucoma patients after trabeculectomy, but its long-term effect is safe and reliable.

OBJECTIVETo observe the efficacy difference in the treatment of breast hyperplasia between the combined therapy of auricular point sticking and Xiaopijian and the simple application of Xiaopijian.
METHODSNinety-one patients were randomized into an observation group (46 cases) and a control group (45 cases). In the observation group, the sticking therapy on the auricular points was applied in combination with the oral medication of Chinese herbal medicine, Xiaopijian. Auricular points included Ruxian, Neifenmi (CO18), Luanchan, Shenmen (TF4), Gan (CO2), Pi (CO13). The auricular point sticking therapy was applied once a week on the auricular points of one side alternatively. Xiaopijian was the self-prepared decoction. The main ingredients are radix bupleuri Bupleurum chinense, spica prunellae prunella vulgaris and radix peoniae alba Paeonia lactiflora, 30 mL each time, three times a day. In the control group, Xiaopijian was simply prescribed for oral administration, 30 mL each time, 3 times a day. The treatment was discontinued during menstruation in the two groups. The menstrual cycle of one month made one session of treatment. The treatments for 3 sessions were observed. The scores of symptoms and physical signs, including the degree of breast pain, hardness and size of breast masses as well as the scores of general and supplementary symptoms were compared before and after treatment in the patients of the two groups. The clinical efficacy was compared between the two groups.
RESULTSAfter treatment, the scores of symptoms and physical signs were reduced apparently as compared with those before treatment in the patients of the two groups (both P<0. 05). The score reduction in the observation group was much more than that in the control group (11.02±1. 78 vs 9.82±1. 53, P<0. 05). The total effective rate was 95.7% (44/46) in the observation group, higher apparently than 80. 0% (36/45, P<0. 05).
CONCLUSIONThe combined therapy of auricular point sticking and Xiaopijian achieves the superior efficacy on breast hyperplasia as compared with the simple application of Xiaopijian.

Objective To discuss the diagnosis and management of adrenal cortical carcinoma. Methods 12 cases of adrenal cortical carcinoma were evaluated with regard to clinical,pathologic characteristics and prognosis.Of the 12 patients,6 were male and 6 were female with an average age of 37.The tumor was functional in 4 and nonfunctional in 8.The tumor was on the right side in 10 and on the left in 2.The diameter of the tumor was 3~30 cm.3 cases were Sullivan stage Ⅰ,3 stage Ⅱ,2 stage Ⅲ and 4 stage Ⅳ. Results Tolal ablation of the tumor has been conducted in 11 and biopsy only in 1.Estrogen receptor expression was positive in 5 out of 7 as deteted by immunohistochemistry assay.Five patient died within 1.5 years after operation whereas the other 7 are still surviving including 5 administered with tamoxifen. Conclusions Adrenal cortical carcinoma may be an estrogen-dependant tumor,so tamoxifen is an effective adjuvant drug in the treatment.Tumor size and stage appear to be strongly correlated with prognosis,larger size and higher stage are associated with a poor prognosis.
