OBJECTIVE: To investigate the clinical features of primary biliary cirrhosis (PBC) and its treatment by integrated traditional Chinese and western medicine. METHODS: 16 PBC patients were observed. Ursodeoxycholic acid (UDCA) was used in the dose of 13 to 15 mg.kg(-1).d(-1), with some traditional Chinese herb prescription. Results (1) The proportion of women to men was 15:1, the mean age was 52.5 years. AMA-M2 was positive in 14 subjects (87.5%). Biliary tract enzymes and ESR were elevated in all subjects. The ratio of hypercholesterolemia (CHOL) and abnormality in IgM was high (62.5%). Fatigue, pruritus, arthralgia, jaundice, splenomegaly were noted in more than half cases. Every patient had one to four complications. (2) ALP, GGT and Glb declined evidently after 3 months' treatment by western medicine associated with traditional Chinese medicine, and declined markedly after 12 months' treatment (P<0.05 respectively). TBIL and CHOL declined gradually during the treatment course. Symptoms and signs were lightened. CONCLUSION: PBC has complicated and especial clinical features. UDCA therapy is effective in PBC, while traditional Chinese medicine has extraordinary effect in treating the symptoms and signs.

OBJECTIVE:To observe analgesic efficacy of oxycodone acetaminophen after posterior lumbar fusion,and to opti-mize spinal postoperative analgesia plan. METHODS:In retrospective study,120 patients underwent posterior lumbar fusion were selected from the Affiliated People's Hospital of Hubei Medical College during Jun. 2013-Jun. 2014,and then divided into observa-tion group and control group according to therapy plan,with 60 cases in each group. Observation group was given oxycodone acet-aminophen 330 mg orally 6 h after surgery,and then 330 mg orally on 1st,2nd day after surgery,tid. Control group was given celecoxib 200 mg 6 h after surgery,and then 200 mg on 1st,2nd day after surgery,bid. Postoperative analgesic efficacy (VAS score) at resting state and active state,postoperative gastrointestinal motility recovery (the time to flatus) and the occurrence of ADR were observed in 2 groups after surgery. RESULTS:Whether at the resting state or the active state 24,48,72,120 h after surgery,VAS score of observation group was significantly lower than that of control group,with statistical significance(P<0.05). There was no statistical significance in the time to flatus and the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Oral administration of oxycodone acetaminophen possesses good effect to relieve spinal postoperative pain,showing fast and safe analgesic efficacy.

The property theory of Chinese herbal medicine (CHM) is regarded as the core and basic of Chinese medical theory, however, the underlying mechanism of the properties in CHMs remains unclear, which impedes a barrier for the modernization of Chinese herbal medicine. The properties of CHM are often categorized into cold and heat according to the theory of Chinese medicine, which are essential to guide the clinical application of CHMs. There is an urgent demand to build a cold/heat property classification model to facilitate the property theory of Chinese herbal medicine, as well as to clarify the controversial properties of some herbs. Based on previous studies on the cold/heat properties of CHM, in this paper, we described a novel strategy on building a cold/heat property classification model based on herbal bio-effect. The interdisciplinary cooperation of systems biology, pharmacological network, and pattern recognition technique might lighten the study on cold/heat property theory, provide a scientific model for determination the cold/heat property of herbal medicines, and a new strategy for expanding the Chinese herbal medicine resources as well.
