OBJECTIVE: To identify the difference of CA IX and P-gp expression level between laryngeal squamous cell carcinoma (LSCC) and benign tissues, evaluate the relationship of these two proteins in LSCC, and their correlation with clinical and pathological features. METHOD: Immunohistochemical detection of CA IX and P-gp were performed in 47 cases of LSCC and 20 cases of vocal cord polyps. RESULT: Overexpression of CA IX and P-gp both in LSCC and in vocal cord polyp (P < 0.05) were confirmed, with a correlation between the two proteins in LSCC (r = 0.324, P < 0.05). The expression of CA IX was related to clinical staging and lymph node metastasis in LSCC (P < 0.05). While P-gp was related to clinical staging and histological grading in LSCC (P < 0.05). CONCLUSION The overexpression of CA IX and P-gp may play a role in LSCC progression.

OBJECTIVETo observe the effectiveness of Bushen Huoxue Decoction in improving the erectile function of male patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) with stent implantation.

METHODSEighty male CHD patients after PCI with stent implantation were equally assigned to receive conventional Western medicine (control group) and combination of Western medicine with Bushen Huoxue Decoction (treatment group), both for 3 months. Then we compared the pre- and post-medication IIEF-5 scores between the two groups of patients.

RESULTSCompared with pre-medication, the total IIEF-5 score was significantly increased after 3 months both in the treatment group (8.19 ± 2.87 vs 17.83 ± 4.92, P <0.05) and in the control (7.98 ± 2.96 vs 12.18 ± 3.69, P <0.05), even higher in the former than in the latter group (P <0.05), and so were the scores on the 5 specific items (all P <0.05). The total effectiveness rate was 72.5% in the treatment group, significantly higher than 47.5% in the control (P <0.05). No obvious adverse reactions and events were observed during the treatment in either of the groups.

CONCLUSIONBushen Huoxue Decoction can obviously improve the erectile function and the quality of the sexual life of CHD patients after PCI with stent implantation.

OBJECTIVE To discuss the surgical methods and their long term efficacy of management of the parotid tumor.METHODS The clinical data of 86 cases with parotid tumor underwent operation between 1997 and 2004 in our hospital were retrospectively analyzed.There were 53 male and 33 female with their age from 23 to 84 years(mean 57 years old). All the patients underwent superficial parotidectomy or extensive superficial parotidectomyenl or total parotidectomy.Selective or functional neck dissection was carried out in some cases.The function of facial nerve was evaluated after operation in all patients. Postoperative radiotherapy was performed in all malignant cases with a dose of 50 to 70 Gy.The patients were followed-up for 36 to 120 months.RESULTS There were 73 benign cases and 13 malignant cases. Five of 8 malignant tumors were found in deep lobe gland.Only one benign tumor locally recurred.The local- regional control rate of the benign tumor was 98.3%. The 3-year survival rate and local-regional control rate in malignant neoplasm were 69.2 % and 84.6 % respectively.The cervical lymph nodes metastasis rate was 23.1% in postoperative pathologic study.The facial nerve preservation rates were 97.3 % and 69.2 % in benign and malignant cases respectively.CONCLUSION The superficial parotidectomy is the basic surgical method.Extensive superficial parotidectomy or total parotidectomy can be used if necessary.The facial nerve and its branches should be preserved during operation. The malignant tumor is more frequently found in deep lobe of the parotid gland.

OBJECTIVETo observe the efficacy and safety of Jingui Shengqi Pill in treating partial androgen deficiency in aging males (PADAM), and to explore the new approach in improving the quality of life in PADAM patients.

METHODSForty patients with PADAM were treated with JSP, the efficacy was evaluated with international index of erectile function (IIEF) scoring, PADAM questionnaire scoring, hormone, prostatic specific antigen (PSA), etc., and the data before treatment were compared with those after treatment in the same group.

RESULTSAfter 3 months of treatment, PADAM scoring and IIEF scoring were all significantly improved. Symptoms regarding physical ability, vasomotion, and psychical and mental condition all got improved more markedly than symptoms regarding sexual hypofunction. The serum level of testosterone was 3.85 +/- 0.36 before treatment and 5.02 +/- 0.83 after treatment (P < 0.05); luteinizing hormone of 7.33 +/- 2.14 and 4.84 +/- 1.43 (P < 0.01), follicle-stimulating hormone of 10.22 +/- 4.48 and 6.47 +/- 3.28 (P < 0.01), respectively. The level of PSA failed to change significantly (1.94 +/- 0.55 and 2.06 +/- 0.47, P > 0.05).

CONCLUSIONJSP is effective and safe in treating PADAM, the mechanism of it is different from supplementing extrinsic androgen. It may have produced the effect by means of favorably regulating the condition of sex hormone to improve the balance of pituitary-sex gland axis, so it has more extensive clinical application.

OBJECTIVETo investigate the anti-inflammatory effects on the vessel wall of rosuvastatin in apolipoprotein E-deficient mice.

METHODSEight-week-old apolipoprotein E-deficient mice fed a normal chow diet were treated with vehicle or various doses of rosuvastatin (1, 5, or 20 mg/kg) by subcutaneous injection for 2 or 6 weeks prior to sacrifice. Endothelial adhesiveness for monocytes was determined by functional binding assay. The expressions of vascular cell adhesion molecule-1 and monocyte chemotactic protein-1 in the vessel wall were detected by quantitative real-time polymerase chain reaction.

RESULTSEndothelial adhesiveness for monocytes was significantly attenuated after 2 or 6 weeks treatments with 5 or 20 mg/kg rosuvastatin. Rosuvastatin also significantly reduced the expressions of vascular cell adhesion molecule-1 and monocyte chemotactic protein-1 in the vessel wall.

CONCLUSIONThe anti-inflammatory effects of suvastatin might be responsible for attenuating the pathogenesis of atherogenesis in apolipoprotein E-deficient mice.
