Objective To analyze the therapy method and the therapeutic effect of Jones fracture by using hollow screw internal fixation.Methods All the Jones fractures were treated by open reduction hollow screw internal fixation and the plaster external fixation were not used after operation.Results The 32 cases with Jones fractures got excellent 25 cases,good 6cases and poor 1 case which used by Maryland foot score system to appraisal.All the cases were followed up for 6 months to 30 months and the average follow-up time is 18 months.Conclusion The treatment of hollow screw internal fixation was a satisfactory method to cure Jones fracture,which had get advantages of simple operation,small wound,short operation time,not external fixation,quick recovery and few complications.

Objective To observe the effect of nasal inhalation of Compound Acorus Liquid(CAL) and oxygen on the recovery of nervous function in cerebral infarction patients.Methods Forty ischemic stroke patients were equally randomized into the treatment group and the control group.The two groups received anti-fibrinogen drug,antiplatelet aggregation drug,and symptomatic treatment;additionally,the treatment group received nasal inhalation of CAL and oxygen,and the control group received nasal inhalation of CAL and oxygen.Ten times constituted one treatment course,and the treatment lasted two courses.Therapeutic effect was evaluated,and the changes of nervous function were assayed by MESSS scoring and Barthel index,and activities of daily life(ADL) were also observed.Results The total effective rate was 90.0% in the treatment group and 55.0% in the control group(P

Objective: To study the chemical constituents in the twigs and leaves of Ervatamia hainanensis. Methods: The chemical constituents were isolated by silica gel, ODS, Sephadex LH-20 column chromatographies, and preparative HPLC. The structures were elucidated on the basis of physicochemical properties and spectral analysis. Results: Four lignans were isolated and identified as threo-7-O-ethylguaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (1), threo-guaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (2), erythro-guaiacylglycerol-8-O-4'-(coniferyl alcohol) ether (3), and dehydrodiconiferyl alcohol (4). Conclusion: Compound 1 is a new 8-O-4'-neolignan and named as hainanervaligan A (1), and compounds 2-4 are obtained from the plants of Ervatamia (A. DC.) Stapf for the first time.

Objective To investigate enhanced CT scanning in differentiation of solitary pulmonary nodule and relationship between the degree and pattern of enhancement and vascularity. Methods 11 patients with surgically confirmed pulmonary carcinoma and 13 patients with inflammatory nodules and 6 patients with tuberculoma were studied with plain chest CT sean and enhanced scanning after injection of 100 ml iodinated contrast medium to observe the enhancement degree and pattern of the lesion before the surgery. Vaseularity of specimens of 11 carcinoma and 13 inflammatory nodules and 6 tuberculoma were examined pathologically and correlated with degree of enhancement. Results The pulmonary carcinoma and inflammatory nodules showed a significantly higher degree of enhancement than tuberculoma. But the carcinoma and the inflammation showed no differences in degree and pattern of enhancement. The degree of enhancement was positively correlated with the number of blood vessles. The vascularity of carcinoma and inflammation was far richer than that of tuberculoma. Conclusion The results suggested that the enhanced CT scanning are distinctively different between carcinoma and tuberculoma,whereas little different between carcinoma and inflammation. Vascularity of the lesion plays an important role in the manifestation of enhancement.

Mutations detection of circulating tumor DNA can be divided into quantitative and qualitative classifications:the forumer mainly detects the total amount of circulating DNA (serum or plasma),whereas the latter mainly detects the specific genetic variations in serum or plasma DNA,such as gene mutations,methylations of tumor suppressor genes,and microsatellite alterations,etc.Both of them may reflect the tumor presence and disease severity.In this paper,mutations detection and its clinical significance of circulating tumor DNA in patients with hepatocellular carcinoma are reviewed.

[Objective]To investigate the curative effect of intermittent pneumatic compression(IPC) in the treatment of deep venous thrombosis(DVT) after interventional thrombolysis.[Method]Fifty-two cases of DVT were treated from December 1998 to August 2007,and divided into 2 groups randomly.In the first group,all cases received low molecular heparin and warfarin after routine or interventional thrombolysis.In the second group,IPC was used on the basis of group one.Two groups were compared about cases for repeated thrombolysis,time point of symptom relief,reduction of swelling at 7 days after surgery,re-canalization of vein at 1 month after surgery.[Result]Three cases in the first group needed repeated thrombolysis while none was found in the second group.In the second group,quicker symptom relief,more obvious reduction of swelling,wider re-canalization of vein were observed compared with the first group.[Conclusion]IPC is proved effective in the comprehensive therapy of DVT.

Objective To investigate the effects of glucocorticoid(GC) on the expression of CD80 and CD4+CD25+T cells in peripheral blood lymphocyte of patients with multiple sclerosis (MS). Methods With flow cytometer,the positive rates of CD80 and CD4+CD25+T cells in peripheral blood lymphocyte were detected in 21 acute MS patients pre and post treatment separately,and compared with the nomal control group.The secols of Expanded Disablility Status Scale(EDSS) were compared pre and post treatment in MS patients.Results The positive rate of CD80[(5.031?1.782)%]in the MS patients pre treatment was obviously less than that in control group's [(6.436?2.035)%](P

Objective: To study the chemical constituents in the leaves of Morus atropurpurea and their biological activity. Methods: The chemical constituents were isolated by silica gel, ODS, Sephadex LH-20 column chromatographies, as well as HPLC. Their structures were elucidated on the basis of physicochemical properties and spectral analysis. The inhibitory effect of the compounds on α-glucosidase was tested by pNP method. Results: Eighteen compounds were isolated from the leaves of M. atropurpurea. Their structures were identified as 1-deoxynojirinycin (1), fagomine (2), cytidine (3), 2-(1', 2', 3', 4'-tetrahydroxybutyl)-5-(2″, 3″, 4″-trihydroxybutyl)-pyrazine (4), 2-(1', 2', 3', 4'-tetrahydroxybutyl)-6-(2″, 3″, 4″-trihydroxybutyl)-pyrazine (5), 2-(1', 2', 3', 4'-tetrahydroxybutyl)-5-(1″, 2″, 3″, 4″-tetrahydroxybutyl)-pyrazine (6), quercetin 3-O-β-D-glucopyranoside (7), kaempferol 3-O-β- D-glucopyranoside (8), kaempferol 3-O-β-rutinoside (9), cichorioside (10), roseoside (11), phytol (12), umbelliferone (13), 1H-indole-3-aldehyde (14), ethyl trans-caffeate (15), sucrose (16), β-sitosterol (17), and daucosterol (18). Conclusion: Compounds 5, 6, 14, and 15 are isolated from the plants of Morus Stapf. for the first time, and compounds 3, 4, 7-13, and 16 are firstly reported from M. atropurpurea.

Objective: To compare the in vivo pharmacokinetics of curcumin-phospholipid complex-chitosan microspheres (Cur-PLC-CM), Cur-PLC, Cur-CM, and crude drug of Cur, and to discuss the advantage of PLC-CM as carrier. Methods: SD rats were ig administered with the above four preparations 100 mg/kg (corresponding to Cur), respectively. Then blood samples were obtained at certain time points. The concentration of Cur in blood was analyzed by HPLC method using emodin as internal standard. The mobile phase was acetonitrile-2% acetic acid (55:45). Concentration-time curve was drawn and the data were analyzed by DAS program. Results: The tmax and t1/2 of Cur-PLC-CM were 2.0 and 3.2 h, respectively, which were much longer than those of crude drug (0.6 and 1.2 h), Cur-CM (1.4 and 2.3 h), and Cur-PLC (1.2 and 1.7 h). The AUC of Cur-PLC-CM was 7.49, 2.07, and 2.67 times as those of crude drug, Cur-CM, and Cur-PLC. Conclusion: The PLC-CM have better sustained-releasing and absorption property than CM and PLC, which may have a great potential to be used as oral delivery system for the low solubility and short half-life drug.
