To explore the clinical effect of alendronate combined with Jintiange capsules in the treatment of postmeno-pausal osteoporosis ( PMOP) . Methods:Ninety-eight cases of PMOP patients were randomly divided into three groups. The combina-tion treatment group (34 cases) was treated with alendronate tablets combined with Jintiange capsules, while the control group A (32 cases) and the control group B (32 cases) was respectively treated with alendronate tablets and Jintiange capsules, and the treatment course was six months. The changes of the clinical symptom score, bone mineral density ( BMD) , serum calcium, serum phosphorus, AKP, hepatorenal function and so on before and after the treatment were recorded. Results:After the six-month treatment, the clinical symptom score of the treatment group was much better than that in the two control groups(P<0. 05). BMD in the three groups was in-creased after the treatment(P<0. 05), and the increase in the treatment group was more notable than that in the two control groups(P<0. 05). Conclusion:Alendronate combined with Jintiange capsules can effectively improve BMD and relieve clinical symptoms in the patients with PMOP, which is worthy of promoted application.

Objective To research the effect of the Kiss-1 gene promoter methylation on the Kiss-1 gene expression in colorectal carcinoma tissue,and to analyze the relationship between the Kiss-1 gene methylation and the clinical pathological features of colorectal carcinoma and its clinical significance.Methods The Kiss-1 gene promotor region methylation,Kiss-1 gene mRNA and protein expressions were detected respectively by methylation-specific PCR, Real-time PCR and Western blotting method in 126 cases of colorectal carcinoma tissue and para-cacinoma normal colorectal tissue.Results The positive rate of Kiss-1 gene methylation in colorectal carcinoma tissue (83.33%)was significantly higher than that in normal tissue (30.16%)(P<0.05).In the cancer tissue,the expression levels of Kiss-1 gene mRNA and protein in Kiss-1 gene promoter methylation positive group was lower than that in Kiss-1 gene promoter methylation negative group (P < 0.05 ). The positive rate of Kiss-1 gene promoter methylation in T3+T4 stage group was higher than that in T1+T2 stage group (P<0.05),but the Kiss-1 gene mRNA and protein expression levels were lower than those in T1+T2 stage group (P<0.05).In the poorly and moderately differentiated group,the positive rate of Kiss-1 gene promoter methylation was higher than that in well differentiated group (P<0.05 ), but the mRNA expression level of Kiss-1 gene was lower than that in well differentiated group (P<0.05 ). In lymph node metastasis group, the positive rate of Kiss-1 gene promoter methylation was higher than that in lymph node negative group (P<0.05),but the mRNA and protein expression levels were lower than those in lymph node negative group (P<0.05 ). And the positive rate of Kiss-1 gene promoter methylation in distant metastasis group was higher than that in non-distant metastasis group (P<0.05), but the mRNA and protein expressions levels were lower than those in non-distant metastasis group (P<0.05). There were no significant associations between the positive rate of Kiss-1 gene promoter methylation and the gender, age,tumor location, and tumor diameter of the patients (P>0.05 ). Conclusion The Kiss-1 gene promoter methylation in colorectal carcinoma tissue is associated with the Kiss-1 gene expression level and the malignant characteristics of colorectal carcinoma;Kiss-1 gene promoter methylation may be used as a reference indicator for predicting the risk of metastasis of colorectal carcinoma.

Objective To investigate the different components of Acorus tatarinowii and Polygala tenuifolia(volatile oil, aqueous extract)on the expression of phosphorylated Tau protein at site Ser396 and Tau-5 in the hippocampus of rats with Alzheimer′s disease(AD). Methods Male Sprague Dawley rats were randomly divided into 8 groups:normal control group, model control group,low-,middle-,and high-dose groups of volatile oil of Acorus tatarinowii and Polygala tenuifolia,and low-, middle-,and high-dose groups of aqueous extract of Acorus tatarinowii and Polygala tenuifolia. The subacute aging model was established by intraperitoneal injection of D-galactose( D-gal). Rats were given different components of Acorus tatarinowii and Polygala tenuifolia(crude drug dosage,0.6,1.2,1.8 g·kg-1 )in experimental groups,and 0.9% sodium chloride solution in normal control group and model control group,by gavage for 28 days.The levels of phosphorylated Tau protein at site Ser396 and Tau-5 were detected in hippocampal tissues by Western blotting and immunohistochemistry. Results The levels of phosphorylated Tau protein at site Ser396 were significantly enhanced in the model control group,as compared with those in normal control group (P<0.01).The relative expression levels of Tau protein Ser396 were 3.83±0.10,3.35±0.01,3.11±0.01,2.75±0.03,2.93±0.01,2.55± 0.07,and 2.23±0.08 in model control group,low-,middle-,and high-dose groups of volatile oil of Acorus tatarinowii and Polygala tenuifolia,and low-,middle-,high-dose groups of aqueous extract of Acorus tatarinowii and Polygala tenuifolia,respectively.Two components of Acorus tatarinowii and Polygala tenuifolia could dephosphorylate Tau protein Ser396 to vary degrees in a dose-dependent manner.The aqueous extract component was slightly better than the volatile oil component,especially in the high-dose group(P<0.01).But Tau-5 did not change significantly after treatment with Acorus tatarinowii and Polygala tenuifolia(P>0.05). Conclusion Acorus tatarinowii and Polygala tenuifolia could promote the dephosphorylation of Ser396 site of Tau protein in the hippocampus of AD rats,with the aqueous extract component having better effects.

BACKGROUND: Clinically Alzheimer disease (AD) is characterized by obscurity in onset, decline of intelligence, and dysfunctions of behavior and nerve system. The essence of AD is impairment of memory and cognition.OBJECTIVE: To explore the effective mechanism of tiaoxin recipe (TXR)and bushen recipe (BSR) in treating AD.DESIGN: Randomized controlled study.SETTING: Shanghai Institute of Traditional Chinese Medicine for Geriatrics.PARTICIPANTS: Totally 60 AD patients were selected from Shanghai Institute of Traditional Chinese Medicine for Geriatrics from October 1999to January 2000.METHODS: Sixty patients with AD were divided into 3 groups, with 20in each group. The patients in TXR and BSR group took respectively TXR and BSR 10 mL once, 2 times per day. The patients in donepezil (Dp)group took a Dp capsule once a day, h.s (Dp was produced in England Boots Company, 5 mg per capsule). For a course consisted of 12 weeks.The changes of Mini mental state examination (MMSE) score, Activity of Daily Living Scale (ADL) score, neuropsychological testing (NPT) score,including FULD object-memory evaluation (FOM), rapid verbal retrieval (RVR), digit span test (DS) and block design (BD), as well as the overall operational evaluation before and after treatment were analyzed.MAIN OUTCOME MEASURES: Scores of MMSE, ADL, NPT and the overall operational evaluation.RESULTS: Totally 60 patients entered the final analysis. ① MMSE scores in the 3 groups were decreased after treatment as compared with those before treatment (P ＜ 0.01). Total effective rates were 70%, 65% and 75% respectively (P ＞ 0.05). ② ADL scores in the 3 groups were decreased after treatment as compared with those before treatment (P ＜ 0.05or P ＜ 0.01). Total effective rates were 45%, 45% and 40% respectively (P ＞ 0.05). ③ Total effective rates were 70%, 65% and 75% respectively (P ＞ 0.05). ④ Scores of FOM were increased in the TXR and the Dp group after treatment as compared with those before treatment (P ＜ 0.05). RVR scores in the three groups were increased after treatment as compared with tbose before treatment (P ＜ 0.05); DS scores were increased in TXR group and Dp group after treatment as compared with those before treatment (P ＜ 0.05 or P ＜ 0.01); and BD scores in BSR group were increased after treatment as compared with those before treatment (P ＜ 0.05).CONCLUTION: TXR, BSR and Dp can improve cognitive function and daily living ability of AD patients, and TXR and BSR are effective TCM drugs in treating AD.
