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.

BACKGROUND: Study on bone tissue-engineered material is one of the most successful fields in tissue engineering, but the mechanism on synthesis of artificial bone has not been known in many aspects.OBJECTIVE: To explore the mechanism of collagen and calcium phosphate (CP) in artificial bone synthesis.DESIGN: Single sample experiment was designed.SETTING: Material Research Room of Honghe University.MATERIALS: The experiment was performed in Material Research Room of Honghe University from July to August 2003. The materials included collagen (10 g/L acetic acid solution), calcium chloride, sodium dihydrogen phosphate (SDP), sodium hydroxide (NaOH), Tris, hydrochloric acid and deionized water (DI water).METHODS: Liquid nitrogen freezing and freeze-drying were used to prepare collagen-CP complexes A and B and the samples at different times during mineralization. UV spectrophotometer was used to determine the biomineralized dynamic curve of collagen-CP. Based on law of curve, the different times of sample collection were determined in preparation of electronic microscopic samples. According to electronic microscopic pictures and spectral data, mechanism analysis was carried on.MAIN OUTCOME MEASURES: Morphology of collagen-CP complex and law of its structure with time changeRESULTS: ①Under agitation, collagen-CP complex A was sheaf-like or needle-like in structure manufactured with retarded neutralization. ②Under static state, with biomineralization, collagen-CP complex B was in layered structure at initial phase of mineralization, which was similar to the self-assembled structure of pure collagen and the molarratio of C, O, P and Ca was 7.26: 20: 0: 2. At the end of mineralization, the structure was strip-like in high density with a certain grains and very fine rills and the molar ratio of C, O, P and Ca was 11.02: 22.5:1.06: 2.CONCLUSION: At the early phase of biomineralization, collagen iscoordinated initially with calcium ion, calcium-carrier layered collagen template is formed with the self-assembling of collagen, and then phosphates is combined with calcium ion to manufacture calcium phosphate in the formed template. By controlling agitation and acting time, collagen complex material of reticular and spinal structure is obtained.

Objective To explore the perinatal outcomes of women with pulmonary hypertension complicating congenital heart disease(CHD).Methods Clinical data of 45 cases of pregnant women with pulmonary hypertension complicating CHD from Apr 1995 to May 2007 were analyzed and they were divided into three groups:29 cases of slight group[pulmonary hypertension of 30 mm Hg(1 mm Hg=0.133 kPa) to 49 mm Hg],8 cases of moderate group(pulmonary hypertension of 50 mm Hg to 79 mm Hg)and 8 cases of severe group(pulmonary hypertension equal to or higher than 80 mm Hg).The types of CHD,cardiac functional status(New York heart association,NYHA),gestational weeks of pregnancy termination,mode of delivery,pregnancy after CHD operation and outcomes of infants were compared between the groups. Results(1)The highest incidence of CHD were atrial septal defect and ventricular septal defect(58%, 26/45).The rate of pregnant women after CHD operation was 29%(13/45),they were mainly in slight group and their NYHA class were in Ⅰ-Ⅱ.(2)The occurrence rate of NYHA class Ⅲ-Ⅳ was 7/8 in severe group.The rate of NYHA class Ⅰ-Ⅱ as 6/8 in moderate group.The rate of NYHA class Ⅰ- was 97%(28 /29)in slight group.(3)The rate of term delivery was 93%(27/29),preterm labor 3% (1/29),abortion 3%(1/29),and the birth weight was(3153?399)g on average in slight group.The rate of term delivery was 5/8,preterm labor occurred in 3 cases in moderate group.The rate of term delivery was 5/8,preterm labor occurred in 2 cases,and iatrogenic abortion in 1 case in severe group.The average birth weight between slight group and moderate or severe group had a significant difference.(4)Caesarean section rate was 78 %(35/45)among all patients.The rate of cesarean section delivery was 76%(22/29)in slight group,6/8 in moderate group,and 7/8 in severe group.(5)The rate of pregnant women who had portent heart failure or heart failure was 24%(11/45),overall maternal mortality was 4%(2/45).Conclusions The higher the pulmonary hypertension,the worse the outcome of the mother and fetus;The pregnant women with good heart function after cardiac operation would have a good perinatal outcome.Cesarean section is more suitable for those women.

In order to explore the clinical hypolipidemic features of Daidai flavone extract, the pharmacokinetics features of characteristic active ingredients of Daidai flavone extract in normal and hyperlipemia rats were studied and compared. The study established the quantitative determination method of naringin and neohesperidin in plasma by UPLC-MS. Study compared the pharmacokinetics differences of naringin and noehesperidin in normal and hyperlipemia rats on the basis of establishment of hyperlipemia model. Results indicated that the pharmacokinetics features of characteristic active ingredients of Daidai flavone extract in normal and hyperlipemia rats showed significant differences. The C(max) of naringin and neohesperidin in hyperlipemia rats plasma after oral administration of Daidai flavone extract increased obviously, while t1/2, MRT and AUC0-24 h decreased, compared to normal rats. But t(max) showed no differences to that of normal rats. The results further proved Daidai flavone extract would have better hypolipidemic effect in the hyperlipemia pathological status. And the characteristic active ingredients naringin and noehesperidin were the material base of Daidai flavone extract to express the hypolipidemic effect.

OBJECTIVETo diagnose achondroplasia prenatally by FGFR3 gene detection.

METHODSSeventy-eight fetuses affected by short-limb dysplasias were recruited. Umbilical blood sampling was employed to obtain fetal blood for karyotyping and FGFR3 gene detection. Genomic DNA was extracted, and the exon 10 of the FGFR3 gene was amplified. PCR amplicons were analyzed by DNA sequencing and restriction fragment length polymorphism with Bfm I. The FGFR3 exon 10 from the parents of the positive fetuses was screened by the same method.

RESULTSIn 78 fetuses affected with short-limb dysplasias, 8 cases had G1138A heterozygotic mutation and normal karyotype, and were diagnosed as achondroplasia. The other 70 fetuses had normal nucleotide at nucleotide 1138 in exon 10 of FGFR3, therefore were excluded from achondroplasia. Only one father in parents of the 8 achondroplasia fetuses also had the G1138A mutation.

CONCLUSIONAchondroplasia could be diagnosed prenatally in the fetuses affected with short-limb dysplasias by using PCR-RFLP and DNA sequencing of the exon 10 of the FGFR3 gene.
