OBJECTIVE: To evaluate the effects of the therapy mainly for strengthening healthy energy to promote blood circulation in treating diabetic patients with gangrene. METHODS: A series of 112 diabetic patients with gangrene were investigated before and after treatment in the changes of wounds, clinical symptoms and quality of life. RESULTS: Fifty-eight cases were cured, 12 cases showed response, 36 cases improved, and 6 cases failure of treatment. The total obvious effect rate was 62.5% (70/112) and the amputation rate was 8.9% (10/112). The 104 diabetic cases of three-stage gangrene were classified into grade I, II and III. The total effect rates of the diabetic cases of grade I, II and III were 83.3% (30/36), 55.6% (35/63) and 20% (1/5), and the amputation rates were 0%, 12.7% (8/63), and 40% (2/5) respectively. After the treatment, the clinical symptoms, gangrene number, gangrene area and gangrene depth were obviously improved (P<0.05), and the quality of life was obviously improved (P<0.01), especially in physical condition, emotional well-being and therapeutic effects on patients (P<0.05). CONCLUSION: Strengthening healthy energy to promote blood circulation is effective in treating diabetic patients with gangrene.

A new computer-assisted vector-cardiogram analyzing system Model TJ-IV developed based on Model TJ-III, has been using in the routine clinical work in order to evaluate its features and performances. The system employs a 586 computer with a CPU of 120 MHz, a special low-noise amplifier, a 12 bit A/D tranducer and the C language for programming. The examinations of 206 cases were performed and all the vector-cardiograms were analyzed by the computer system and by manipulative methods respectively. In comparison with the manipulative methods the system has a very high accuracy of picture-recognition. The accuracy for distinguishing the onsets and terminals of orthogonal ECG waves is 98% while that for distinguishing the peaks and troughs of the waves is 100%. These waves include P, Q, R, S, R' and S' waves. The new system is capable to provide the parameters of more than 591 items, including 46 newly-developed diagnostic parameters. The testing and analyzing of 12 parameters of orthogonal ECG and plane VCG have proved that the results of the aboved two methods have no difference. The new system has a very high accuracy of picture-recognition and index calculation with many technical problems existing in the old versions, solved--a great improvement of safety and anti-interference and an increase of the detecting & diagnostic speed.

Chronic ulcer of the lower extremities amounts for a grave and serious problem for public health. Western medicine focuses on controlling infection, improving blood circulation, surgical debridement, skin grafting, etc, but there are bottlenecks in the treatment. Traditional Chinese medicine (TCM) has a long history and a legacy of sound clinical efficacy in this area. TCM has developed a unique, effective external theory, and a large number of topical prescriptions and external technology. Through this research, a safe and effective treatment protocol of TCM for chronic ulcer of the lower extremities can be formed. To this end, during China's "Eleventh Five-Year" Plan, special research committees and projects on TCM external treatments and external technologies were established. This study on ulcer of the lower extremities constitutes one of the major research topics.

OBJECTIVESTo transfer 1.3-fold-overlength genome of HBV expression plasmid into HepG2 cells, and observe the dynamic changes of viral replication as well as expression in the transfected cells.

METHODS4.1 kb fragment of HBV genome, derived from pGEM-HBV, was cloned into Hind III site of the eukaryotic expression vector pCDNA3.1 to construct the recombinant plasmid pHBV. Then HepG2 hepatoma, cells were transfected with pHBV, using Lipofectamine2000 transfection reagent. After 24, 48, 72 hours, the levels of HBsAg and HBeAg in the supernatant of HepG2 cells were determined with Abbott MEIA Kit. Intracellular viral DNA and RNA were analyzed by Southern and northern blot hybridization. In addition, viral-specific proteins (HBsAg and HBcAg) were assayed by immunofluorescence staining.

RESULTSThe expression vector pCDNA3.1 was constructed successfully. The levels of HBsAg were 5.36+-0.25, 13.42+-1.24, 7.52+-0.43, and the values of HBeAg were 9.16+-0.32, 22.75+-1.49, 15.96+-1.03 after 24, 48, 72 hours, respectively. All expected HBV replicative intermediates and specific transcripts were verified by Southern and northern blot analysis. The HBsAg-positive cells peaked after 24 hours, and then dropped slowly. HBsAg positive staining scattered in the cytoplasm, whereas HBcAg lied maily in the cytoplasm apart from nuclears.

CONCLUSIONSThis recombinant plasmid, which initiates viral replication efficiently in infected cells, is expected as a novel tool for investigating HBV replication in vitro.
