Expression of epidermal growth factor receptor (EGFR) in SK BR 3 cells, a human breast carcinoma cell line,was analysed with immunohistochemistry. Inhibitory effects of TP40 on SK BR 3 cells growth and protein synthesis were analysed with crystal violet staining and 3 H leucine incorporation. Competitive assays were performed by the addition of excess of EGF. The results showed that the SK BR 3 cells exhibited large amounts of brown immunoperoxidase reaction indicative of EGFR. When the concentration of TP40 was in the range of 1 100?g/L,TP40 inhibited SK BR 3 cell growth and protein synthsis in a dose dependent form. An excess of EGF could completely block inhibitory effects of TP40. The results suggested that the human breast carcinoma SK BR 3 cells express EGFR at a high level. TP40 could significantly inhibit the growth of SK BR 3 cells. The cytotoxic effects of TP40 were specifically mediated by EGFR.

[Objective] To compare and analyse the clinical effect of tiny incision blind-cut suck-erasion on unhairing and preserving armpit hair in bromhidrosis.[Method] Select 429 cases of 851 sides in our hospital, divide them into treatment group(blind-cut suck-erasion+unhairing) 308 cases with 609 sides, and control group(blind-cut suck-erasion+preserving armpit hair) 121 cases with 242 sides. Make statistics and compare their complications in recent and forward stages, also the recurrence and residual of peculiar smel after 1 year. [Result] For the treatment group, 38 sides had the recent compli-cation of hematoncus, 30 sides had partly skin necrosis, 12 had bad cut cure, 70 had early slight hardening and contracture skin; for the forward complica-tions: 27 sides had focal slight scar, 3 severe scar, 23 focal subcutaneous sac lump with infection, 3 peculiar smel residual and recurrence. To the control one, for the recent complications, 11 sides had hematoncus, 9 partly skin necrosis, 5 bad cut cure, 13 early slight hardening and contracture skin; for for-ward complications, 8 sides had focal slight scar, 1 severe scar, 3 focal subcutaneous sac lump with infection, 38 peculiar smel residual and recurrence. By comparison, on early slight hardening and contracture skin and focal subcutaneous sac lump with infection, the treatment group was higher than control one;other complications had no difference of statistical meaning;on radical cure rate, the treatment group was obviously more than control one, with dif-ference of statistical meaning. [Conclusion] The tiny cut blind-cut suck-erasion is definite in treating bromhidrosis, the operation removes subcutaneous apocrine sweat gland, meanwhile removes the hair fol icle and sebaceous gland complexus, the therapy is very thorough, with better cure effect, less recur-rence, without increasing complications.

Objective To compare the curative effects and safety of mirtazapine and fluoxetine in treatment of elderly depressive patients with insomnia.Methods 92 cases of elderly depressive patients with insomnia were randomly divided into two groups: the mirtazapine treatment group and the fluoxetine treatment group. The period of treatment was six weeks. The antidepressant effect was assessed with the drop rate of Hamilton Depression Scale (HAMD),the effect of improving sleep was assessed with HAMD sleep disturbance factor and the Pittsburgh Sleep Index (PSQI), and the administration of security was assessed with vice Treatment Emergent Symptom Scale (TESS).Results After treatment, the effective rate of the mirtazapine group was 90.9% (40/44), that of the fluoxetine group was 84.1% (37/44). In the end of 1st, 2nd, and 4th weeks after treatment, the difference between the two groups were significant (P<0.001). At the end of 6th week, the difference was not significant (P>0.05) in HAMD; the difference was significant in HAMD sleep disturbance factor and PSQI score (P<0.05).Conclusion The clinical effects of mirtazapine in treatment of depression are similar to that of fluoxetine, but mirtazapine takes effects fast, can improve the symptoms of insomnia, has higher safety and better compliance, and is more appropriate for the depressive elderly patients with insomnia than fluoxetine.

OBJECTIVE: To analyze the effects of Astragalous Injection on oxidative stress and micro-inflammatory status in patients undergoing maintenance hemodialysis (MHD). METHODS: Sixty MHD patients were included and randomized into treatment group and control group, with another 10 healthy volunteers as normal control. The patients in the treatment group were treated with Astragalous Injection and the patients in the control group were treated with normal saline for 12 weeks. A spectrophotometric method was used for the measurement of plasma concentrations of oxidative parameters including advanced glycation end products (AGEs), advanced oxidation protein product (AOPP), malondialdehyde (MDA) and vitamin E (Vit E). The content of C-reactive protein (CRP) was evaluated by enzyme-linked immunosorbent assay. RESULTS: Compared with the normal control group, the plasma levels of AGEs, AOPP, MDA and CRP were significantly increased, while plasma level of Vit E was significantly decreased in MHD patients ( P<0.01). After Astragalous Injection treatment, the plasma levels of AGEs, AOPP, MDA and CRP were decreased as compared with the control group ( P<0.01), while there was no significant difference in plasma Vit E level between the treatment group and control group. CONCLUSION: There exist oxidative stress and micro-inflammation in MHD patients. Astragalous Injection can ameliorate the accumulation of oxidative products and micro-inflammatory status, but it has no significant effect on plasma Vit E level.

OBJECTIVEThis study aimed to induce carcinogenesis of lingual mucosa in C57BL/6 mice by feeding them 4-nitroquinoline 1-oxide (4NQO) solution.
METHODSA total of 85 C57BL/6 mice were randomly divided into distilled water control group (DD group, n=5), 1,2-propylene glycol control group (PG group, n=5), and experimental group (EP group, n= 75). The mice in the experimental group were medially fed in 15 cages. By contrast, the mice in DD, EP, and PG groups were watered with distilled water, 50 mg.L-1 4NQO solution, and 1,2-propylene glycol solution. The mice in EP group were executed every two weeks from week 0, and the mice in the control groups were sacrificed at the 28th week. The mice were weighed. Mucosal lesions were measured by macroscopic observation and histopathologic detection.
RESULTSOne mouse in EP group died of unknown reason. The weight of the mice in EP group presented weight loss compared with the mice in DD and PG groups after the 24th week. Seventy-nine macroscopic lesions were observed in the lingual mucosa, oral floor, and upper palatal and buccal mucosa. A total of 70 macroscopic lesions (88.6%) were located in the lingual mucosa. Mucosal lesions changed from simple hyperplasia to squamous cell carcinomas. Well-differentiated squamous cell carcinomas were observed in all mice of EP group by pathological section at the 28th week. No lesion was found in the mice of DD and PG groups.
CONCLUSIONThe animal model of lingual squamous cell carcinomas was successfully established. The periods from 12th to 16th week and 20th to 28th week were the ideal times for the research on pathogenesis of early and medial-advanced stage during carcinogenesis of squamous cell carcinomas.

Objective To study the prognostic value of fragmented QRS (fQRS) in the recurrence of cardiac events in acute STEMI patients underwent emergency percutaneous coronary intervention (PCI). Methods Ninety-two acute STEMI patients who underwent emergency PCI were enrolled. The presence of fQRS was evaluated by a 12-lead ECG in 72 h after PCI. Cardiac events (myocardial infarction, need for revascularization or cardiac death) and all-cause mortality were recorded in all patients during 12 months follow-up. Results Cardiac event rate[15 (31.3%) vs. 4 (9.1%)]were higher in the fQRS group (n=48) compared with the non-fQRS group (n=44) during a mean follow-up of 12 months. A Kaplan-Meier survival analysis revealed significantly lower event-free survival for cardiac events in the fQRS group (P < 0.004). The results of Cox regression model analysis revealed that signiifcant fQRS was an independent signiifcant predictor for cardiac events (HR 2.19, 95%CI 1.38-3.50, P=0.023). Conclusions The presence fQRS is an independent risk factor for poor prognosis in STEMI patients undergoing emergency PCI.
