Objective To evaluate the changes of platelet activity before and after anti-platelet treatment in pa?tients with coronary heart disease, and their responsiveness to clopidogrel through detecting the phosphorylation levels of va?sodilator stimulated phosphoprotein (VASP). Methods Twenty-eight cases of healthy people were selected as control group . Patients with chronic stable angina pectoris (CSA, n=95) were randomly divided into A (48 cases) group and B (47 cases) group,and were given clopidogrel 75 mg/d or 150 mg/d respectively;Patients with non ST segment elevation acute coronary syndrome (NST-ACS, n=67) were all given 300 mg loading dose of clopidogrel at the first time, then randomly divid?ed into C (33 cases) group and D (34 cases) group, and given clopidogrel 75 mg/d and 150 mg/d respectively. Blood were tak?en to examine the phosphorylation levels of serum VASP by ELISA before taking clopidogrel, at time point of loading dose and the fifth day of clopidogrel administration . Results Before treatment, phosphorylation levels of serum VASP were low?er in A, B, C, D groups than those in the normal control group(P<0.05). After treatment of clopidogrel for 5 days: ① In group A and group B ,phosphorylation levels of serum VASP did not change compared to that before treatment (P>0.05).②In group C and group D, phosphorylation levels of serum VASP were significantly increased at loading dose and the fifth day of clopidogrel administration than those before treatment (P<0.05), but there were no significant differences in phosphory?lation level of VASP was lower group between group C and group D after serum treatment (P > 0.05). Conclusion The phosphorylation level of serum VASP was lower in patients with coronary heart disease than that in normal control group. Clopidogrel can improve the phosphorylation level of serum VASP in NST-ACS patients .

Objective To investigate the clinical characteristics, location, treatment and prognosis of periosteal osteosarcoma. Methods The data of 1 patient with periosteal osteosarcoma was retrospectively analyzed, and the 35 cases reported in CNKI database in recent years were analyzed. Results The patient of periosteal osteosarcoma was female and 16 years old. Periosteal osteosarcoma occurred in the tibia. The patient was treated with extensional resection, and had no recurrence and metastasis 3 months after operation. Among the 35 patients reported in the literature, the age of onset ranged from 14 to 35, the female was slightly more than the male (19 cases vs. 16 cases), and the lesion site was mainly in the tibia and femur. The 35 patients underwent surgical treatment, and 4 cases had metastasis;6 cases were treated by surgery combined with chemotherapy. Conclusions Female patients with periosteal osteosarcoma were slightly more than male, and the lesion site is mainly in the tibia and femur. The chemotherapy effect is not exact, and extensional resection is the most effective treatment method. The transfer site and the characteristics are not exact.

BACKGROUND:In recent years, the incidence of diabetic foot is sharply increasing, which tends to cause foot ulcers, amputation and death.
OBJECTIVE:To investigate the clinical therapeutic effect of autologous bone marrow stem cel transplantation combined withdanggui huoxue tangon diabetic foot.
METHODS:Sixty patients with diabetic foot accompanied by chronic lower limb ischemia were randomly divided into conventional treatment group including 20 cases with 38 affected limbs, and autologous bone marrow stem cel transplantation group (cel transplantation group) including 20 cases with 36 affected limbs, and combined group (autologous bone marrow stem cel transplantation combined withdanggui huoxue tang) including 20 cases with 39 affected limbs. After 12 weeks of treatment, indicators such as limb cold-feeling, pain, skin temperature, claudication distance and ankle brachial index were measured, and meanwhile, complications and adverse reactions were observed in the folow-up visit.
RESULTS AND CONCLUSION: In the conventional treatment group, there was no significant change before and after treatment (P > 0.05). However, these indicators were significantly improved in the other two groups after treatment (P < 0.05) as wel as compared with the conventional treatment group (P < 0.05). In addition, there was no adverse reaction in the cel transplantation group. These findings indicate that the combination of autologous bone marrow stem cel transplantation anddanggui huoxue tang has effective effects on diabetic foot.

Objective To investigate the genetic diversity of five populations of cultivated Morinda officinalis in Guangdong Province using random amplified polymorphic DNA(RAPD).Methods Sixty-four individuals in five populations of cultivated M.officinalis were analyzed by RAPD markers to determine the genetic variations among the populations.The data of genetic diversity were analyzed with Popgen32 software.Results The levels of genetic variation and patterns of population structure in M.officinalis were investigated using RAPD markers.Of the 100 primers screened,15 primers produced highly reproducible RAPD bands,using these primers,224 discernible DNA fragments were generated with 112(50.00%) polymorphic fragments,indicating considerable genetic variation at the species level.In contrast,there were relatively high levels of polymorphism at the population level with the percentage of polymorphic bands ranging from 37.05% to 53.13%,and the mean percentage of polymorphic loic(P=45.86%).Genetic variation among populations was detected based on Nei's genetic diversity analysis(0.175 6),Shannon's diversity index(0.287 6) for every population with Shannon's index 0.103 3—0.236 2 and Nei's indexes 0.074 5—0.154 0.Conclusion There is a little genetic differentiation among populations of cultivated M.officinalis and result in different cultivated types,the genetic diversity with M.officinalis(POP2) is higher than that of other populations.It may be the main reason of the difference of cultivated M.officinalis quality.

Objective To investigate the expression and clinical significance of BRMS1 ( breast cancer metastasis suppressorl ) protein in colon cancer.Methods The expression of BRMS1 protein was detected by using EliVision immunohistochemical techniques in 46 cases of colon cancer,and adjacent non cancerous colon tissues.The clinical significance with histopathologic records was aralyzed.Results The expression levels of BRMS1 ( 34.8％ ) in the colon cancer tissues was significantly lower than those of adjacent non cancerous colon tissues( x2 =23.92,P ＜0.01 ).The expression of BRMSl was significantly correlated with tumor size,clinical stage,and lymph node status (x2 =6.02,4.28,4.35,all P＜0.01) ;BRMS1 had no correlation with age,pathological type.Conclusion BRMS1 might synergistically promote the metastasis of colon cancer.Detection of the expression of BRMS1 may be hdpful in determineing the prognosis of colon cancer.

OBJECTIVE: To investigate the pathological factors of syndrome pathomechanism through studying the correlation between syndromes of posthepatitic cirrhosis and biological parameters. METHODS: Clinical information of three hundred and fifty-five patients with posthepatitic cirrhosis was collected and the database was established. Parameters with statistical significance were analyzed with multi-factor regression analysis to investigate the main influencing factors of the syndromes of posthepatitic cirrhosis. RESULTS: Formulae of six syndromes, including syndrome of yin deficiency of liver and kidney, syndrome of damp heat, syndrome of stagnated heat smoldering, syndrome of yang deficiency of spleen and kidney, syndrome of stagnation of liver qi and spleen deficiency and syndrome of blood stasis due to qi deficiency, were established with stepwise regression analysis. CONCLUSIONS: One of the pathophysiological bases of syndrome of blood stasis due to qi deficiency in cirrhosis is synthetic dysfunction of hepatocytes. The pathophysiological basis of syndrome of damp heat is inflammatory injury, which is also syndrome of stagnated heat smoldering in cirrhosis patients. The relationship between syndrome of yin deficiency of liver and kidney and stasis and damp heat may be the pathophysiological basis of the posthepatitic cirrhosis..

A total of 144 patients with Graves disease were divided into 3 groups according to their disease courses (≤ 1 year,1 year ＜ course ≤ 5 years,＞ 5 years).The bone metabolic biochemical markers and bone mineral density (BMD) of 144 patients with Graves disease and 26 normal controls were observed.Compared with control group,serum levels of calcium,phosphate,alkaline phosphatase and urinary levels of phosphate and magnesium in Graves disease patients were significantly increased(P ＜ 0.01 or P ＜ 0.05),but serum levels of magnesium and 25 (OH) D3,1,25 (OH)2D3 were significantly decreased (P ＜ 0.01 or P ＜ 0.05).BMD of all sites in patients were significantly lower than that of normal controls (P ＜ 0.01 or P ＜ 0.05).
