Chemical investigation was carried out to study the alkaloids from stems of Nelumbo nucifera and their cytotoxic activities. The constituents were separated by column chromatography, and their structures were elucidated by spectroscopic data analyses. The isolated compounds were evaluated for their cytotoxic activities by MTr method. Fifteen compounds were isolated from the total alkaloids extract and identified as asimilobine (1), isococlaurine (2), N-acetylnorarmepavine (3), crykonisine (4), velucryptine (5), pycnarrhine (6), liriodenine (7), nuciferine (8), nornuciferine (9), armepavine (10), N-methylasimilobine (11), coclaurine (12), N-norarmepavine (13), N-methylcoclaurine (14) and lysicamine (15). Compounds 1-7 and 12-15 were isolated from stems of this plant for the first time, and compounds 2-6 were firstly isolated from the family Nelumbonaceae. Compounds 7-10, 13 and 14 showed significant cytotoxic activities against HL-60 carcinoma cell line with inhibitory ratios of 51.36%, 59.09%, 52.51%, 53.93%, 51.43%, and 64.31% at concentration of 1 x 10(-5) mol x L(-1), respectively.

OBJECTIVETo establish the steriod-induced osteoporosis model with the type of Kidney-Yin deficiency.

METHODSTotally 45 female Kunming mice were randomly divided into normal group,model group and Liuwei Dihuang pills(Chinese character: see text)group. The model was established by intramuscular injecting of Dexamethasone. Liuwei Dihuang pills (Chinese character: see text) group was administered orally with Liuwei Dihuang pills (Chinese character: see text). The signs and symptoms of mice were observed dynamically. All the animals were sacrificed at the end of the 6th weeks. The level of ACTH, cAMP, cGMP, TSH and E2 in serum were detected to evaluate deficiency of Kidney-Yin. Morphological changes and bone density were observed to evaluate osteoporosis.

RESULTS(1) Compared with control group, mice in model group appeared obvious Kidney-Yin deficiency symptoms, including hair dry, restlessness, excitability, hard stool, and yellow. (2) Compared with control group,the weight of mice in model group gained slower (P<0.01); the index of adrenal gland,liver and spleen decreased (P<0.01, P<0.01 ,P<0.01); the level of ACTH and TSH increased (P<0.01 ,P<0.01), the level of E2 decreased (P<0.01) and the ratio of cAMP/cGMP increased (P< 0.05). (3)Compared with control group,the bone density of lumbar vertebra and femur in model group were significantly decreased (P<0.01, P<0.05); HE staining revealed osteoporosis in model group mice. (4)However, the Liuwei Dihuang pills (Chinese character: see text) group can partly antagonize the inhibition of the HPA axis, alter the disordered sex hormone and the ratio of cAMP/cGMP, and reverse the osteoporosis partly.

CONCLUSIONthe model of osteoporosis with type of Kidney-Yin deficiency could be established by Dexamethasone intramuscular injection. With less interference, it wight be a stable and reliable modeling method for integration of disease and syndrome in TCM.

Objective To investigate the therapeutic effect and mechanism of ribavirin to mice viral myocarditis. Methods Onehundred and twenty mice were randomly divided into 3 groups. Group 1 was normal control group 1 .group 2 CVB3 control group, group 3 ribavirintherapy group. In the latter two groups, 0.2 mL CVB3(10-7.5Tcid5o/mL)was infected into abdominal cavity. Ten mice of each group were killed at the 7 th, 14 th,21 st,28 th day. Mice motality,light and electron microscape, myocardial viral tiler, myocardial pathological score,serum cTnI,malonytdialdehyde(MDA) and cardiac myocyte apoptosis rate(CMAR) were examined.Re-sults The motality,myocardial viral titer,myocardial pathological score,cTnI were lower in group 3(ribavirin therapy group) than in group 2(CVB3 control), and MDA and CMAR were no significant differences between ribavirin group and simple CVB3 group. Conclusion Ribavirin has good treatment effect to mice viral myocardilis,and its mechanism is due to decrease viral titer.

Objective:The purpose of this study is to investigate the expression of tumor stem cell marker aldehyde dehydrogE-nase 1 (ALDH1) in breast cancer and its clinical significance. Methods:The expression of ALDH1 protein was examined by immunohistochemical staining in 92 breast cancer tissues. The correlation analysis and diseasE-free survival analysis of patients was evaluated based on the clinical follow-up data. Results:Expression of ALDH1 protein had a significant correlation with progesterone receptor (PR) and cerb-B2 (P<0.05), but had no significant correlation with age, tumor size, clinical staging, and lymph node metastasis (P>0.05). The 2-year diseasE-free survival rate of AlDH1-positive patients was lower than that of ALDH1-negative patients (P<0.05). ALDH1-positive patients, who received CEF regimen chemotherapy and hormone therapy, had lower 2-year diseasE-free survival rate than that of ALDH1-negative patients (P<0.05). Conclusion:The decreased diseasE-free survival rate of ALDH1-positive patients is related with drug resistance. ALDH1 could be used as an independent factor for predicting the prognosis of breast cancer.

OBJECTIVETo study the clinical effect of arthroscopic excision of popliteal cysts through a combined anterior and posterior approach.

METHODSFrom January 2010 to December 2012,20 patients with popliteal cysts were treated with arthroscopic excision. There were 14 males and 6 females, with an average age of 49.5 years old, ranging from 45 to 65 years old. The lump has been found for 4 to 18 months,with a mean time of 12 months. Their mean sagittal diameter was 4.5 cm (ranged from 3 to 7 cm). There were 12 popliteal cysts in the left and 8 popliteal cysts in the right. The main clinical manifestation included lump at popliteal fossa, swelling and pain at knee joint and some extent of dysfunction. All diagnoses were determined according to MRI, which clearly showed the communication of cyst and articular cavity. The cyst was removed under arthroscopy, through the posterior approach and then the intra-articular lesion was treated via the anterior approach. According to Rauschning and Lindgren classification, 2 patients were grade I, 6 patients were grade II, and 12 patients were grade III. The guidelines of Rauschning and Lindgren were used to evaluate the clinical effects.

RESULTSNo complications such as the injury of blood vessel and nerve, or incision infection occurred in all patients. All the patients were followed up, and the duration ranged from 8 to 24 months, with a mean time of 16 months. According to the criteria of Rauschning and Lindgren, there were 14 cases of grade 0, and 6 cases of grade I after operation, which was improved obviously compared with that pre-operation. No cyst reoccurred and the knee joint pain was relieved.

CONCLUSIONTreatment of popliteal cysts with arthroscopic excision through a combined anterior and posterior approach is effective to remove the cyst sac and treat intra-articular diseases simultaneously, resulting in the decrease recurrence rate of cyst.
