Objective: To explore the clinical features of hypokalemic periodic paralysis, and compare clinical features of primary group with those of thyrotoxicosis secondary group. Methods: Clinical data of 44 patients with hypokalemic periodic paralysis in Peking University First Hospital from 1996 December to 2008 December were retrospectively analyzed. Results: There were 22 patients in primary group, and 22 in thyrotoxicosis group. Identical clinical features of both the groups; (1 ) It had a predilection in young men. (2)Main symptoms were limb movement disorder and fatigue, and paralysis recurrent attacked in most patients. (3) 40. 9% to 68. 2% patients had obvious incentives, and the common ones were a heavy meal, sweet drinks, or strenuous'exercise. (4) Serum potassium levels of the two groups were obviously lower than the normal range. (5) In 20% patients of primary group and 25% patients of thyrotoxicosis secondary group, CK levels were higher than normal, while LDH and HBDH levels were normal.(6) The doses of potassium replishment were not correlated to serum potassium levels at the onset. Different clinical features of the two groups; (1) Patients of thyrotoxicosis group had hypermetabolism symptoms and thyroid dysfunction. Patients of primary group had no hypermetabolism symptoms, and all of them were euthyroid. (2) Serum potassium levels of thyrotoxicosis secondary group were lower than those of primary group significantly [(2.25±.67) vs (2.78±.49) mmol/L, P=0;007]. (3) Hyperkalemia is easier than primary group to rebound in thyrotoxicosis secondary group, after replenishment of potassium. Conclusion: Hypokalemic periodic paralysis has its clinical features, and patients with early diagnosis and replenishment of potassium in time have good prognosis. The doses of potassium replenishment are not determined by serum potassium levels at the onset. Hyperkalemia is easier to rebound in thyrotoxicosis secondary group after replenishment of potassium, serum potassium levels should be monitored closely, and hyperthyrosis radically cured.

Purpose:To evaluate the effectiveness and safety of the second-line treatment in patients with advanced non small cell lung cancer(NSCLC). Methods:23 patients with histologically and /or cytologically confirmed advanced NSCLC were treated with docetaxel(taxotere) 75mg/m 2 on d1 every 3 weeks. All patients had received prior platinum-containing chemotherapy and relapsed or progressed after receiving one prior chemothergpy regimen. Results:23 patients were available for evaluation: partial response (PR) was 17% (4/23), stable disease(SD)and progressive disease(PD) was 57% (13/23) and 26% (6/23), respectively, there was no complete response (CR). The response rate was 17% (4/23) and the median survival of all patients was 9 months .one -year survival rate was 39% (9/23) . Hematologic toxicity was the main side effect, and they were well tolerated. Conclusions:Taxotere as second-line treatment of NSCLC is effective, and toxicity is tolerated.

0.05). For the toxicity,Neutropenia and anemia were common in the three regimens. Thrombocytopenia was significantly mild on the NP regimen. For the PC regimen,gastrointestinal toxicity and nephrotoxicity were mostly mild,and peripheral neurotoxicity was most common. Conclusions:Efficacy was not significantly different between the three investigated regimens. These regimens could be use as first-line chemotherapy in advanced NSCLC. Toxicities of these regimens were different,so clinicians should apply the chemotherapy according to individual characteristics of patients.

Purpose:To determine the efficacy and toxicity of gemcitabine plus cisplatin in anthracyclin- and taxane-pretreated patients with advanced breast cancer. Methods:Chemo-resistance was defined as no response while rece iving first-line and/or second-line chemotherapy. Patients with advanced and c hemo-resistant breast cancer, which was confirmed histologically, received gemc itabine 1,000 mg/m 2 on d1, 8 and cisplatin 25 mg/m 2 on d1-3, every 3 weeks.2 cycles were delivered at least. Results:30 female patients were enrolled in this trial. All pat ients were evaluable for response and toxicity. The median age was 46 years (ran ge, 34-58 years). After 2-4 (median, 3) cycles of chemotherapy, overall object ive response was 50.0%, with 5 CRs (Complete response 16.7%) and 10 PRs (Partial response 33.3%). Stable disease was seen in 13 patients (43.3%), and disease pr ogression in 2 patiens (6.7%). Toxicities included myelosuppression and gastroin testinal reaction mainly. Grade Ⅲ-Ⅳ toxicites developed in 50% patients. Ther e were no treat-related deaths. The median follow-up time was 12.5 (range: 2- 48) months. Median overall survival was 14 months, and median time to progressio n was 10 months. Conclusions:These data indicate that the combination of gemcita bine and cisplatin is an effective treatment for heavily pretreated breast cance r patients with manageable toxicity.
