OBJECTIVE:To study the effect of catalpol on the activity and apoptosis of osteoclasts (OC) in the osteoblasts (OB)-OC co-culture system and its mechanism. METHODS:OB and OC were isolated respectively from the SD rats of 1-3 days and 5-7 days old to establish OB-OC co-culture system. After treated with 0(blank control),0.05,0.5,5,50 and 100 mg/L catal-pol for 48,72 and 96 h,the number of bone absorption lacuna for OC was observed by inverted microscope to reflect OC activity. After treated with 0(blank control)and 0.05 mg/L catalpol for 48,72 and 96 h,the activity of tartrate resistant acid phosphatase (TRACP)in OC was detected,and the apoptosis rate of OC was calculated. After treated with 0(blank control)and 0.05 mg/L ca-talpol,mRNA expression of osteoprotegerin(OPG)in OB was detected. RESULTS:In OB-OC co-culture system,the number of bone absorption lacuna in 0.05-50 mg/L catalpol groups was significantly lower than blank control group(P<0.01),indicating ca-talpol could inhibit OC activity,especially 0.05 mg/L catapol. Compared with blank control,0.05 mg/L catapol lowered the activity of TRACP but increased the apoptosis rate of OC(P<0.05);mRNA expression of OPG was up-regulated in OB(P<0.01). CON-CLUSIONS:In OB-OC co-culture system,catalpol can inhibit the activity of OC and induce the apoptosis of OC,and its mecha-nism may be associated with the mRNA expression up-regulation of OPG in OB.

BACKGROUND:Studies have shown the bone mineral density of postmenopausal women is closely related to parathyroid hormone. But there are differences in different areas.
OBJECTIVE:To investigate the association between BstBⅠ polymorphism of parathyroid hormone gene with bone mineral density in postmenopausal women from Fuzhou area.
METHODS:The bone mineral densities of the lumbar spine, femoral neck, trochanter and Ward’s triangle were measured in 150 postmenopausal women by dual energy X-ray absorptiometry. The genotype of parathyroid hormone gene was determined by polymerase chain reaction-restriction fragment length polymorphism.
RESULTS AND CONCLUSION:(1) The distribution of parathyroid hormone genotypes were BB genotype 68.8%, Bb 24.1%, and bb 7.1%. The B al elic gene frequencies reached 81%, while b was 19%. The distribution fol owed the Hardy-Weinberg equilibrium. (2) Analysis of the relationship between the genotypes and bone mineral density:There was no significant difference in the bone mineral densities of the lumbar spine, femur, neck, trochanter and Ward’s triangle among the three genotypes (P>0.05). BstBⅠ gene polymorphism of parathyroid hormone gene is not correlated to bone mineral density, and there is no enough evidence to support genotype of parathyroid hormone gene as a genetic marker in predicting the risk of developing osteoperosis in Fuzhou postmenopausal women.

Objective To discuss the effect of group social skills training on improving psychiatric symptoms and disability and the family relationship in patients with schizophrenia.Methods 101 followup patients of rehabilitation with schizophrenia in mental health center of a top three hospital and in a community were chosen from June 2011 to August 2012.Based on the principle of voluntary,45 and 56 patients were grouped into the control group and the intervention group,respectively.The scores of psychiatric symptoms,mental disability and family relationship were compared between two groups by independent sample test.Results At the end of six months,the score of positive and negative symptoms and mental disability were lower in the intervention group,and there was significant difference in different measuring time,the interaction existed between the intervention and the measuring time.Meanwhile,the total score of family concern in the intervention group was higher than that in the control group,and there was significant difference in different measuring time,no interaction existed between the intervention and the measuring time.Conclusions Group training of social skills could improve psychiatric symptoms and the family relationship of patients with schizophrenia,reduce mental disability and promote recovery of patients.

Objective To study the clinical and pathological characteristics of breast ductal carcinoma in situ (DCIS) and with microinvasion (DCIS-MI). Methods From June 1999 to June 2003, a total of 41 patients with DCIS and DCIS-MI patients were retrospectively studied. Results Pathology varies between DCIS type Ⅰ, type Ⅱ and DCIS-MI patients. Mammographic calcification was the only presenting symptom in 9.76% of patients with DCIS accounting for 50% of these cases. The accordance rate of mammography with final diagnosis was 80%, and 33.3% of mammography in DCIS-MI type 2 showed mass or chaos of gland construction. The initial symptom in 57% of patients was nipple discharge. For fiberoptic ductoscopy, the accordance rate was 95.65%. There were two local recurrent cases in DCIS-MI type 2. Conclusion Breast ductal carcinoma in situ and with microinvasion had their own characteristics, including different prognosis.

Testing of hypothesis was affected by statistical analysis set division which was an important data management work before data base lock-in. Objective division of statistical analysis set under blinding was the guarantee of scientific trial conclusion. All the subjects having accepted at least once trial treatment after randomization should be concluded in safety set. Full analysis set should be close to the intention-to-treat as far as possible. Per protocol set division was the most difficult to control in blinded examination because of more subjectivity than the other two. The objectivity of statistical analysis set division must be guaranteed by the accurate raw data, the comprehensive data check and the scientific discussion, all of which were the strict requirement of data management. Proper division of statistical analysis set objectively and scientifically is an important approach to improve the data management quality.

Missing data is a common but unavoidable issue in clinical trials. It not only lowers the trial power, but brings the bias to the trial results. Therefore, on one hand, the missing data handling methods are employed in data analysis. On the other hand, it is vital to prevent the missing data in the trials. Prevention of missing data should take the first place. From the perspective of data, firstly, some measures should be taken at the stages of protocol design, data collection and data check to enhance the patients' compliance and reduce the unnecessary missing data. Secondly, the causes of confirmed missing data in the trials should be notified and recorded in detail, which are very important to determine the mechanism of missing data and choose the suitable missing data handling methods, e.g., last observation carried forward (LOCF); multiple imputation (MI); mixed-effect model repeated measure (MMRM), etc.
