ObjectiveTo identify the chemical composition of stem, leaf and peel ofCynanchumchinese R.Br..MethodsFourier IR spectra, the second derivative spectrum and two-dimensional correlation spectroscopy were adopted to identify IR of different parts ofCynanchumchinese R.Br..ResultsIt was found that the IR spectra of the leaf was similar to that of the peel but was different from the stem. What’s more, in the second derivative spectra of the leaf, it showed that the absorption peak was strong at the position of 1 543 cm-1, 1 515 cm-1, 1 499 cm-1 and 1 467 cm-1, respectively and there existed carbonyl absorption peak at 1 738 cm-1 and 1 659 cm-1 in addition. Therefore, it was inferred that flavonoids were the major components while less in the stem and peel.ConclusionsThe differences of the three parts aboutCynanchumchinese R.Br. were studied through IR spectrum macroscopically, which provided reference for exploring the constituents and clinical medication.

Objective To investigate the therapeutic effect of Xiaoxuan Kangfu capsule in treating psoriasis vulgaris. Methods All patients were divided into two groups randomly (60 patients in a control group and 60 patients in a treatment group). In the control group complex Qingdai capsule was given to the patients, with 4 pills for each time and 3 times daily. While in treatment group Xiaoxuan Kangfu capsule was given to the patients with 6 pills for each time and twice daily. 30 days consisted one treatment period for both groups. The patients undertook one to three treatment period according to the patients' pathogenetic condition. The rates of recovery and improvement and were compared. Results In the treatment group, 34 patients were cured (42.5%), and the total effective rate was 87.5%; while in the control group 14 patients were cured (7.5%), and the total effective rate was 72.5%. There was statistic difference between the two groups (P＜0.05). The average heal time of the treatment group was shorter than that of the control group, showing statistic difference (P＜0.05).Conclusion Xiaoxuan Kangfu capsule showed higher recovery rate, shorter healing time and lower recurrence rate in treating psoriasis vulgaris than complex Qingdai capsule. The treatment is deserving clinical spread.

BACKGROUND:Extracorporeal shock wave (ESW) therapy is using principles of liquid-electric conversion and transfer to produce energy gradient difference and torsional tension in tissues with varied density.It is a matured technique in treating urinary and digestive system calculosis.However,the applications of ESW in treating nonunion or delayed osseous union are few.OBJECTIVE:To explore the therapeutic effects of ESW in treating nonunion or delayed osseous union by animal experiment and clinical verification.METHODS:The effect of ESW on periosteal metabolism was explored by focusing extracorporeal wave on bone tissues,and the autoradiography of H~(3-)TdR labeling rate was observed by animal experiment.ESW was used to treat nonunion patients (n=16) or delayed osseous union patients (n=16),and the follow-uP results were evaluated.RESULTS AND CONCLUSION:By autoradiography,the H~(3-)TdR labeling rate was greater in the experimental sides than that of the control sides at 1 and 2 weeks after operation (P＜0.05-0.01),which confirmed that the mitotic activity of periosteal osteoblasts was increased,namely,endosteal osteogenesis was enhanced.Clinical verification results demonstrated that,at 16 weeks after operation,16 patients with delayed union were all cured,13 were cured among the 16 cases of nonunion,and the remained 3 cases had notably callus formation.No adverse events occurred in all cases.The results suggested that it is reliable to treat nonunion or delayed osseous union using ESW therapy.

Silicone rubber with advantages of stable performance, easy-shaping, considerable product bene- fits, has been widely used in biomedical engineering field and health care industries. Nevertheless, the application of silicone rubber in biomedicine is still challenged by its inherent shortcomings. In biocompatibility aspects, disad- vantages of silicone rubber products need to be overcome, including.'hydrophobic surface, poor imaging compatibili- ty, and occurrence of calcification after long-term implantation in body. Experts from all over the world have been studying on means of modifications over the past few years and the researches mainly focus on increasing the surface wettability, enhancing the function of X-ray resistance, and anti-calcification pre-treating. Although initial results are encouraging, biocompatibility of medical silicone rubber is not yet satisfactory.

It is proposed that surviving leukemia stem cell (LSC) is a major contributing factor to leu-kemic relapse because of its molecular and cellular features.Several recent studies have proved that LSC can be eliminated by target therapy.

By introducing the job contents classification of hospital, the paper analyzes each sub-system including its information contents, structure features and construction factors, discusses the plan for establishing electronic medical records with combination of the component of medical records, from sequencing of the system, management mode, noted issues, moreover, suggests that each hospital should accord to own situation establishing own system.
