Objective To evaluated the surgical techniques and results of open reduction and internal fixation performed for ankle fracture. Methods Eighty-two patients with ankle fracture were treated with open reduction and internal fixation from March 1995 to June 1999. Fifty-eight patients with complete clinical data were analyzed. The patient group consisted of 36 males and 22 females. According to Weber-AO classification, the group was made up of 30 Weber B cases,28 Weber C cases. All patients were evaluated with modified Baird and Jackson scoring system. The relationship between final result and fracture pattern, fixation methods, the time of exercise initiation after operation were analyzed respectively. Results The followed-up period varied from 2 months to 52 months, with an average of 17 months. The number of patients whose results was excellent, good, fair and poor was respectively 31, 18, 6 and 3. The total percentage of good to excellent clinical results was 84.5%. Fifty-four ankles were completely pain free and the remainders had only slight pain after long time walking. Conclusion Operative treatment may provide satisfactory fracture reduction and clinical results for ankle fracture. Correct fracture pattern estimation and proper internal fixation is of importance to achieve and maitain reduction, and then, to gain better long term results.

Objective:To establish an HPLC method for the fingerprint determination of glycyrrhizae dispensing granules. Meth-ods:Twelve samples were analyzed by HPLC with glycyrrhizic acid as the reference. The analysis was performed on a Waters SunFire C18 column(250 mm × 4. 6 mm,5 μm) with the mobile phase A of acetonitrile and the mobile phase B of 0. 1% phosphoric acid solu-tion with gradient elution. The flow rate was 1. 0 ml·min-1 , the detection wavelength was 237nm, and the column temperature was 30℃. Results:By analyzing the fingerprint, 21 peaks existed including the peak of liquiritin and glycyrrhizic acid. The similarity of the samples was more than 0. 97. Conclusion:The established HPLC fingerprint of glycyrrhizae dispensing granules is dependable and simple. The method can provide scientific basis for the quality control of glycyrrhizae dispensing granules.

Objective To investigate the effect of TanshinoneⅡA (TSN) on the cell hypertrophy induced by angiotensinⅡ(AngⅡ) in the primary culture of neonatal rat cardiomyocytes. Method The effect of TSN on cardiomyocyte was evaluated by the 3-[4, 5-dimethylthiazol-2-yl] -3, 5-diphenylformazan (MTF) assay. As the index of eardiomyocyte hypertrophy, protein synthesis rate was measured by H-Leucine incorporation and the cell size was determined by phase contrast microscope. The proto-oncogene c-los mRNA and c-jun mRNA expression was assessed using reverse transcription polymerase chain reaction (RT-PCR). Results Exposure of the myocytes to TSN (5～80 mmol/L) for 24hours produced no cytotoxicity. Protein synthesis rate and proto-oneogene c-fos and c-Jun mRNA expression of eardinmyoeytes increased significantly after AngⅡtreatment, and TSN inhibited these effect of AngⅡ.Conclusions TSN can prevent the hypertrophy of eardiomyocytes induced by AngⅡ, which be attributable relate to the decreased expression of proto-oncogene c-los and c-jun mRNA by TSN.

Objective:To establish the HPLC fingerprint for Polygonum cuspidatum dispensing granules. Methods:The HPLC fin-gerprint of 12 batches of Polygonum cuspidatum from different manufacturers were determined. The analysis was performed on a Waters SunFire C18 column(250 mm × 4. 6 mm,5μm)with acetonitrile as the mobile phase A and 0. 05% phosphoric acid solution as the mo-bile phase B with gradient elution. The flow rate was 1. 0 ml·min-1 ,the detection wavelength was 230 nm,the column temperature was 30℃,and the injection volume was 10μl. Results:The results were calculated according to“similarity evaluation system for tradi-tional Chinese medicine chromatographic fingerprint”nominated by CFDA combined with the analysis of the HPLC fingerprints. Totally 14 common peaks with similarity above 0. 98 were found in the HPLC fingerprint of Polygonum cuspidatum,including the peak respec-tively for polydatin and emodin. Conclusion:The method can provide more information for the quality control of Polygonum cuspidatum dispensing granules.

Objective To compare the contents of liquiritin and glycyrrhizic acid between Glycyrrhizae Radix et Rhizoma decoction pieces and its formula granules.Methods HPLC method was used with Waters Atlantis T3 column (4.6 mm × 150 mm, 3μm), flow rate of 0.8 mL/min, detection wavelength of 237 nm, and column temperature at 30℃. The mobile phase was acetonitrile-0.1% phosphoric acid solution gradient elution system. The contents of liquiritin and glycyrrhizic acid of Glycyrrhizae Radix et Rhizoma decoction pieces and its formula granules were determined and compared.Results The contents of liquiritin and glycyrrhizic acid in formula granules were less than that in the decoction pieces of Glycyrrhizae Radix et Rhizoma, which was not in conformity with marked concentration multiple.Conclusion The contents of liquiritin and glycyrrhizic acid in formula granules is greatly different with Glycyrrhizae Radix et Rhizoma decoction pieces. The production process of the formula granules needs to be improved.

For a large-scale hospital, management of medical equipment is very important for its economic benefit and development. This paper discusses the implementation of informatization, supermarketization and automatization for medical equipment inventory management with computer network technology.

Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.

Objective To compare the contents of forsythoside A and forsythin in Fructus Forsythia and its dispensing granule. Methods HPLC-gradient elution method was used with SunFire C18 column (4.6 mm×250 mm, 5μm), mobile phase A of acetonitrile and B of acetic acid, flow rate of 1.0 mL/min, detection wavelength of 277 nm, and column temperature at 30 ℃. HPLC was used to determine the contents of forsythoside A and forsythin in Fructus Forsythia and its dispensing granule, and compare the difference between the two contents. Results The content of forsythoside A in dispensing granule was less than that of raw material of Fructus Forsythia, and the concentration of the major components in the commercial Lianqiao Granule were not equivalent to that in the decoction of Fructus Forsythia. The content of forsythin in dispensing granule was equivalent with that of raw material of Fructus Forsythia. Conclusion The original formula granule production process needs to be improved, and the standardized criteria for the quality control and reasonable quality standard of granule should be established.
