ObjectiveTo study the associated factors with pelvic lymph node metastasis of endometrial carcinoma and the effect of pelvic lymphadenectomy on prognosis of the disease MethodsTotally 102 patients with endometrial carcinoma who underwent pelvic lymphadenectomy (90 patients) or lymph node biopsy (12 patients) in our hospital from Jan 1981 to Dec 2002 were recruited The relationship between various clinicopathologic factors and pelvic lymph node metastasis was analyzed Prognosis of ninety patients with pelvic lymphadenectomy was compared with 90 patients without pelvic lymphadenectomy (control group) in the same period The 5-year survival was calculated by life table method Results The incidence of pelvic lymph node metastasis increased in patients with low grade(46%),deep myometrium invasion(42%), cervical involvement(44%), positive peritoneal cytology(52%), adenexal metastasis(75%) and distant spread(100%) The 5-year survival was lower in patients with lymph node metastasis (37%) than that without lymph node metastasis (89%, P

CXCR4, a receptor for stromal cell-derived factor-1 (SDF-1, also know as CXCL12) and a member of the chemokine receptor family, has been shown to play an important role in the proliferation, migration, invasion and metastasis of breast cancer cells. CXCR4 expression is an early event in breast cancer development and may serve as a biomarker for early detection and diagnosis of breast cancer. Expression of CXCR4 has been demonstrated to correlate with metastasis and poor prognosis in breast cancer. Inhibition of CXCR4 expression may be a potential target of breast cancer treatment.

Objective To evaluate the safety and efficacy of microsurgical resection of large acoustic neurinoma via the suboccipital retrosigmoid approach.Methods Forty-nine patients with large acoustic neurinoma(≥4 cm) underwent microsurgical resection through suboccipital retrosigmoid approach.The craniotomy was performed by way of an unilateral S-shaped suboccipital incision.With microsurgical techniques the outmost layer of the arachnoid membrane was preserved in order to avoid damaging to the surrounding vital structures.The tumor was resected intracapsularly from the superior pole and the internal auditory meatus was finally opened.The last pieces of tumor were removed by sharp dissection from the facial nerve bidirectionally,and were resected cautiously in a piecemeal fashion.Results Of the 49 patients,45 patients(92%) received a total resection of the tumors,and 4 patients(8%) subtotal resection.No patients died.The facial nerve was preserved anatomically in 42 patients(86%) and functionally in 36 patients(73%).The acoustic nerve was preserved anatomically in 7 patients(14%) and functionally in 3 patients(6%).One patient experienced a postoperative haematoma,and a re-operation was required.No recurrence was seen in 37 patients during a follow-up for 6 months ～ 5 years(mean,2.8 years).These patients had recovered for normal work and daily activities.Conclusions Microsurgical operation through suboccipital retrosigmoid approach is a favorable treatment for large acoustic neurinomas.The procedure can improve the rate of total resection,decrease the morbidity and mortality,and effectively protect the function of the acoustic and facial nerves.

Objective:To compare the effect of curing polymyalgia rheumatica either by using both Biqi capsule and prednisone or by using prednisone alone. Methods: Thirty-nine patients of polymyalgia rheumatica were randomly divided into two groups, 18 patients in the treatment group treated with Biqi capsule and small dosage of prednisone; 21 patients in the control group treated with small dosage of prednisone. The therapeutic course was 12 weeks. The patients' symptoms of muscle ache, inflexibility in the morning and T-cell subsets determination (CD4, CD8)were observed and scores of clinical practice was made. Results: The respective total effective rate was 94.44% for the treatment group and 66.67% for the control group. There was distinctive difference in the scores for the treatment group and the control group in relieving the patients of the symptoms of polymyalgia rheumatica. The treatment group would help the patients of polymyalgia rheumatica to improve their immunity ability. Conclusion: The combination of Biqi capsule and prednisone can help to improve the effect of curing polymyalgia rheumatica.

Applying the specialized Master of Public Health (MPH) degree education is one of the most important parts of our nation's medical degree system innovation. It has a positive effect on the development of health care in our country. To ensure the quality of the MPH degree, we should be more careful with course studies, do better in field and social practice, be stricter with degree dissertation rejoining, and supervise and control the process of the training.

Objective To summarize the experience of pterional craniotomy microsurgical resection of giant tuberculum sellae meningiomas. Methods A total of 18 patients with giant tuberculum sellae meningiomas were treated microsurgically in this hospital from February 2000 to November 2004. The patients were operated on by use of pterional craniotomy on the side of worse vision. The basal part of the tumor was firstly dissected to control the blood supply of the lesion. Through the cerebral cisterns at the sellar region and the interfaces between the tumor and the adjacent structures, the tumor was removed to the greatest possible extent with minimal invasion to the neighbouring structures. Results[WTBZ] A total resection was conducted in 16 patients (88.9%), and a subtotal resection, in 2 patients (11.1%). No surgery related death was observed. Follow-up examinations in 14 patients for 3 months ~ 4 years (mean, 2.5 years) found no recurrence of meningiomas. Conclusions[WTBZ] The pterional approach provides excellent exposure of the middle fossa and the parasellar area. Pterional approach microsurgical technique can improve the rate of total resection of giant tuberculum sellae meningiomas.
