Objective: To study the effect of zinc deficiency(ZD)on the gene expression of vitamin D receptor(VDR)and CaBP in duodenal mucosa of rats. Methods: Thirty weaning male rats were randomly divided into three groups:ZD,paired-fed(PF),zinc adaquate(ZA). After 15 d feeding, took the duodenal mucosa to extract RNA,and measured the levels of VDR mRNA and CaBP mRNA in duodenal mucosa by real time fluorescent quantity PCR. Results: The VDR gene expression of ZD group was downregulated 88.89% as that of PF group,and 50.00% as that of ZA group. CaBP gene expression of ZD group was downregulated 80.16% as that of the PF group,and 88.50% as that of ZA group. Conclusion: Zinc deficiency, by changing the activity of VDR and the mRNA expression of VDR,affects the transcription of the target gene CaBP,and then the absorption of calcium that causes allo-osteogenesis.

Objective To study the effectiveness of EEG bio-feedback in ameliorating the attention of children with attention deficit/hyperactivity disorder (ADHD) compared to a control group receiving methylphenidate treatment; and to explore the effectiveness of EEG bio-feedback in treating ADHD children refractory to methylphenidate. Methods Forty-four ADHD children were randomly assigned to an EEG bio-feedback group or a methylphenidate group. An additional twenty ADHD children refractory to methylphenidate were referred to as EEG bio-feedback group B. The two EEG bio-feedback groups received training in enhancing their beta activity and suppressing their theta activity. The methylphenidate group were treated with methylphenidate for 3 months. The subjects′ attention stability was measured using a number cancellation test. Their attention allocation and attention shift were tested using a neuropsychological behavioral test instrument, including trail-making test. All groups received re-tests during treatment, post-treatment and during a 6 month follow-up. Results During treatment, the cancellation speed of children in the EEG bio-feedback group A was slower than that of children in the MPH group. At the end of the treatment, there were no significant differences in speed between the two groups. Six months to one year after treatment the cancellation speed of the EEG bio-feedback group A was significantly faster than that of the MPH group. The EEG bio-feedback group B demonstrated significant increases in their cancellation speeds after 20 treatments and during a 1 year follow-up. During treatment and post-treatment, Q scores were significantly lower in EEG bio-feedback group A than in the methylphenidate group. Six months to one year after treatment the Q scores were significantly higher in EEG bio-feedback group A than in the methylphenidate group. There was no significant increase in the Q scores in EEG bio-feedback group B during treatment, but they increased significantly post-treatment. There was no significant difference in the trail-making time between EEG bio-feedback group A and the methylphenidate group during the treatment. Six months to one year after treatment, the trailmaking times in EEG bio-feedback group A were significantly less than in the MPH group. EEG bio-feedback group B showed significant decreases in trailmaking time post-treatment and during follow-up. Conclusions EEG bio-feedback may produce significant and long-term improvements in attention stability, attention allocation and attention shift. EEG bio-feedback may be useful for children with ADHD when methylphenidate is ineffective.

Objective To assess surgical strategies and its therapeutic effect on treating tumors invading of the great vessels. Methods 23 patients underwent tumor resection along with reconstruction of great vessels from Jan. 2001 to Dec. 2005 were retrospectively reviewed. Results 19 cases (82.6%) experienced radical resection along with reconstruction of great vessels, 4 cases (17.4%) underwent palliative resections. 20 cases (86.9%) were followed up by various imaging examination methods. 4 cases (17.4%) died perioperatively and 7 cases (30.4%) had complications in perioperative period. Up to Aug. 2005, the postoperative survival times in patients were from 1.5 to 59.0 months. 3 cases (15.0%,3/20) existed more than 48 months, 4 cases (20.0%,4/20) more than 36 months, 6 cases (30.0%,6/20) more than 24 months, 9 cases (45.0%,9/20) more than 12 months and 12 cases(55.0%,11/20)more than 6 months. No complications related to vascular graft occlusion and tumor recurrence next to grafts occurred in these patients. In 2 cases appeared partial thrombosis in grafts in perioperatively. Conclusion Combination of radical resection of tumor and reconstruction of great vessels could extend survival time and improve quality of life in selected patients with tumor invading thoracic and abdominal great vessels.

Parkinson's disease (PD) is a complicated disease, commonly diagnosed among the elderly, which leads to degeneration of the central nervous system. It presently lacks an effective therapy for its complex pathogenesis. Adverse effects from Western drug-based medical intervention prevent long-term adherence to these therapies in many patients. Traditional Chinese medicine (TCM) has long been used to improve the treatment of PD by alleviating the toxic and adverse effects of Western drug-based intervention. Therefore, the aim of this study is to evaluate the efficacy and safety of Xifeng Dingchan Pill (XFDCP), a compound traditional Chinese herbal medicine, taken in conjunction with Western medicine in the treatment of PD patients at different stages in the progression of the disease.

Objective To determine the contents of four effective constituents in Euphorbiae Semen decoction;To provide evidence for Euphorbiae Semen decoction into clinical application. Methods Established quantitative analysis multi-components by single marker method was used to determine the contents of diterpenoids constituents, such as euphorbia storoid, euphorbia factor L2, and euphorbia factor L3. HPLC method was used to determine the contents of aesculetin. Results Contents of euphorbia storoid, euphorbia factor L2, and euphorbia factor L3 in smashed Euphorbiae Semen decoction were 0.015 9%, 0.005 9% and 0.024 1%, respectively. However, the contents of the above three constituents could not be detected in whole Euphorbiae Semen decoction. The content of aesculetin (0.693 6%) in smashed Euphorbiae Semen decoction was more than that in whole Euphorbiae Semen decoction (0.288 2%). Conclusion Decoction digestion effect of diterpenoids constituents in Euphorbiae Semen decoction is not good. Decocting with water is not suitable for the clinical application of Euphorbiae Semen for purgation and diuresis. Aesculetin in smashed Euphorbiae Semen decoction has good decoction digestion effect, in which clinical use for antisepsis and anti-inflammation is effective.
