Objective To assess the quality of literature of clinical studies on acupuncture in treatment of chronic fatigue syndrome.Methods The literatures between 1998-2008 were searched by means of electronic retrieval.Type and methodology,general condition,criteria for diagnosis and assessment of therapeutic effects,following-up and side effects etc.in clinical studies were evaluated according to principles and methods of clincial epidemiology and evidence-based medicine.Results Of the 78 literatures enrolled,76 were studied in China and published in Chinese journal of China,only 2 were English literature and published in English journal of China.Only 7 were authentic randomized controlled trials(RCTs),21 quasi-randomized controlled trials and RCTs can't contact with authors,3 non-randomized concurrent controlled trials and 47 narrative studies.50 had clear international recognized diagnostic ctriteria.22 mentioned enrolled or excluded criteria.26 adopted TCM criteria for therapeutic effects,27 evaluated therapeutic effects with grading.4 the sample content above 100,33 between 60 and 99,4 mentioned compliance evaluation,3 described retreat cases,2 reported follow-up.11 reported adverse reaction.Conclustion Clinical studies on acupuncture in treatment of chronic fatigue syndrome were mainly carried through in China,and the quality of study and literature is low comparatively.Therefore,high quality's RCTs with strict design are needed urgently in this area and the researchers should contribute to journals overseas.

This study is to investigate the effects of aqueous extract of Schisandra chinensis Baill (WWZ), kadsurin, schisandrin A, schisandrin B and schisandrol B on rat hepatic CYP3A. Rats received a daily gavage of aqueous extract of WWZ for different times. The livers were harvested after gavage and subjected to microsome preparation. Microsomal CYP3A activity was determined by measuring the amount of the metabolite of testosterone (6 beta-hydroxytestosterone) with HPLC. Aqueous extract of WWZ, kadsurin and schisandrin A were incubated with microsomes obtained from rat. Microsomal CYP3A activity was determined by HPLC. Primary hepatocytes were separated and extracted from rat, then were treated with aqueous extract of WWZ, schisandrin A, schisandrin B and schisandrol B. Then, the expression of CYP3A1 mRNA was analyzed by RT-PCR. As for the in vivo assay, aqueous extract of WWZ significantly inhibited the enzyme activity of CYP3A after 12 h gavage. The inhibitory effect was converted to inductive effect after 3-day gavage. Aqueous extract of WWZ could induce the enzyme activity of CYP3A after 6-day gavage. Aqueous extract of WWZ and kadsurin showed a dose-dependent inhibition of CYP3A (IC50 of 487.8 microg mL(-1) and 6.2 micromol L(-1), separately). In rat primary hepatocytes, aqueous extract of WWZ (2.5 mg mL(-1)), schisandrin A (0.1 micromol L(-1)), schisandrin B (0.1 micromol L(-1)) and schisandrol B (10 micromol L(-1)) increased significantly the expression of CYP3A1 mRNA by 23%, 55%, 42% and 27%, respectively. Aqueous extract of WWZ could show dual effect on the enzyme activity of CYP3A in rat in vivo. Meanwhile, kadsurin showed a dose-dependent inhibition of the enzyme activity of hepatic CYP3A in vitro. And schisandrin A, schisandrin B and schisandrol B showed significant inductive effect on the expression of rat CYP3A1 mRNA.

Immunoglobulins ( Ig ) , also called antibodies, are important components in humoral -mediated immunity. Ig can bind with their receptors, called immunoglobulin receptors ( IgR ) , trigger biologic activities respectively. Different sub-types of Igs show different function. And IgRs have been treated as therapeutic targets in inflammation and immunity related dis-eases for many years. This article reviewed the recent progresses in the study of IgR function and its therapeutic role in inflamma-tion and immunity related diseases.

Cerebrovascular disease, also known as a cerebral vascular accident, is named “stroke” in traditional Chinese medicine, there is close correlation between acute cerebrovascular disease and gastrointestinal system. In this paper, we discussed 3 parts about the relationship between the gastrointestinal system and brain. First, in the traditional Chinese medicine theory, there is close relationship between gastrointestinal system and brain from the physiological function and Meridian theory. Secondly, clinical practice indicated that heat phlegm fu-organ syndrome is the main syndrome of acute cerebrovascular disease. The main symptom of this syndrome is the constipation, which is an important part of the disease transition. Furthermore, in acute cerebrovascular disease, the brain-gut peptide esp. CCK and surface colonic electrical physiological changes are the material and electrophysiological basic on the relationship between gastrointestinal system and brain.

Objective To investigate the feasibility of monitoring the tumor's hypoxic changes by 99Tcm-2-(2-methyl-5-nitro-1H-imidazol-1-yl) ethyl eihydrogen phosphate (MNLS) imaging after radiotherapy.Methods (1) H22 cells were cultured and mice model with liver cancer xenografte was made.The mice were imaged at 0.5,1,2,3,4,6 and 8 h (six mice in each group) after injected with 7.4 MBq 99TcmMNLS when the tumor size reach about 1 cm.Then the mice were sacrificed.The T/NT and ％ID/g of each time point was calculated.(2) The liver cancer bearing mice of radiotherapy group (25 Gy) and control group were imaged at 0,24,48 h,and then the technique of ROI was adopted to calculate the T/NT at each time point in the two groups.Immunohistochemical stain method was used to evaluate the expression level of HIF-1α in liver cancer.(3) One-way analysis of variance,the least significant difference t test,two-sample t test and Spearman correlation analysis were performed.Results (1) The uptake of 99TcmMNLS in the liver cancer bearing mice was significant at 2 h after injection and the ％ID/g was the highest.99Tcm-MNLS was excreted mainly through kidneys.(2) The T/NT and HIF-1α expression level in radiotherapy group at 24 h (2.65±0.27,(50.62±3.78)％) were lower than those at the instant (3.35±0.19,(85.32±0.94)％,t=5.640,6.701,both P＜0.05),but higher than those at 48 h (2.23±0.52,(21.69±0.75)％,t=7.674,4.911,both P＜0.05).The T/NT and HIF-1α expression in the radiotherapy group were significantly higher than those in the control group at the instant (2.74 ± 0.29,(28.26 ± 1.70) ％,t =4.235,3.473,both P＜0.05) but lower at 48 h (3.15±0.88,(67.64±3.55) ％,t =7.902,3.258,both P＜0.05).However,no significant difference was observed at 24 h between radiotherapy group and the control group (2.98±0.16,(58.45±0.98) ％,t =0.525,2.043,both P＞0.05).The change of T/NT closely correlated with the expression of HIF-1α in both the radiotherapy group and control group(r,=0.793,0.756,both P＜0.05).Conclusion 99Tcm-MNLS hypoxia imaging has potential to monitor changes of hypoxia in tumor after radiotherapy.

Lymphoma is a malignancy of mature lymphocytes. Signalling through the B cell receptor ( BCR ) is central to the development and maintenance of B cells. In light of the numer-ous proliferative and survival pathways activated downstream of the BCR, it comes as no surprise that malignant B cells would co-opt this receptor to promote their own growth and survival. Compounds that inhibit various components of this pathway, in-cluding spleen tyrosine kinase(Syk), Bruton’s tyrosine kinase (Btk), and phosphoinositol-3 kinase(PI3K), have been devel-oped. In this paper,the B-cell receptor signaling and its targeted inhibitors of lymphoid malignancies are reviewed.

Purpose To explore the features of 99Tcm-AnnexinⅤscintigraphy of venous thrombus and its feasibility of discriminating fresh venous thrombus from old one. Materials and Methods The rabbits (n=15) were randomly divided into three groups (fresh thrombus group, old thrombus group and control group). The inferior vena cava thrombus models were developed in the rabbits of thrombus groups by inserting screw cooper wire into inferior vena cava. The rabbits of control group received sham operation. 99Tcm-AnnexinⅤwas injected in the rabbits of fresh thrombus group and control group one day after operation;the same was done in the rabbits of old thrombus group 14 days after operation. Planar anterior abdominal images were obtained at 30, 60, 90 and 120 min after 99Tcm-AnnexinⅤinjection in all groups respectively. The ratios of thrombus to background of the two thrombus groups and the ratios of the area correspondent to the thrombus groups to background of the control group were calculated by ROIs counts. Then rabbits were executed, and thrombus was used for pathology examination. Results 99Tcm-AnnexinⅤuptake in thrombi was clearly visualized in all rabbits of the fresh thrombus group;whilst negative images showed in all rabbits of the old thrombus group and control group. The thrombus to background ratios of the fresh thrombus group (4.06±0.49) were higher than that of the old thrombus group (2.46±0.38), and also higher than the inferior vena cava below inferior pole of right kidney level to background ratios (2.27±0.24) of the control group (t=5.746, 7.318;P<0.05). All the thrombi of the fresh thrombus group were confirmed as fresh mixed thrombi by HE staining, and those of the old thrombus group were confirmed as old mixed organized thrombi. Conclusion 99Tcm-AnnexinⅤmay become a new acute venous thrombus imaging tracer used to discriminate fresh venous thrombus from old one.

Objective To research the influence of tangerine peel and pinellia ternata on the expression of VCAM-1 and MMP-9 in carotid atherosclerosis rabbits, and explore its mechanism. Methods Totally 25 male rabbits were divided into control group, model group and Chinese medicine group. Control group was treated with basic diet, model group and Chinese medicine group were treated with both high-fat diet and carotid artery intima-air drying technique. Chinese medicine decoction group was treated with tangerine peel and pinellia ternata decoction, as 10, 8, 6 mL/kg, for 4 weeks. Then the right carotid was cut and fixed, and pathological changes were observed by HE staining. The expressions of VCAM-1 and MMP-9 were observed by immunol histochemistry SABC method. Results Compared with control group, the expression of VCAM-1 and MMP-9 in model group was significantly increased (P<0.01). And compared with model group, tangerine peel and pinellia ternata decoction significantly restrained VCAM-1 and MMP-9 expression (P<0.05). Conclusion Tangerine peel and pinellia ternata could restrained VCAM-1 and MMP-9 expression in carotid atherosclerosis rabbits, suggesting that its mechanism may be related with inhibiting vascular inflammatory reaction and stabilizing plaques.
