The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

Objective To describe the MRI features and pathologic findings of biliary cystadenocarcinoma(BCAC)and to assess the diagnostic value of MRI in those tumors.Methods Five cases of BCAC were collected.All cases were proved by pathology.Non-enhanced and multiphase-enhanced MRI were performed in all cases.MRCP were performed in two cases.The MRI features of the five cases were reviewed retrospectively and correlated with pathologic findings.Results Histological evidence demonstrated five cases of BCAC.Four cases were solitary,whereas the other case was multifocal.All cases were solid and cystic lesions.Two cases were unilocular,whereas the other three cases were multilocular. Multiple mural nodules and irregular thickening cystic walls were presented in all cases.The cystic parts of the lesions were homogeneous in signal intensity and showed no enhancement after contrast administration in the five BCAC.Septa were present in three BCAC with multilocular cyst.On MRCP the bile duct dilatation was found in two BCAC.Conclusion MRI can reveal the characteristic findings of BCAC and accurate preoperative diagnosis can be made.

Objective: This study aims to analyze the therapeutic effect and prognostic factors of carcinoma of parotid gland (CPG). Methods: Data on 103 CPG patients were retrospectively analyzed. The patients were divided into the simple surgery group (Group One) and post-operative radio-chemotherapy group (Group Two). Kaplan-Meier survival analysis, Log-rank test, and Cox re-gression analysis were employed to analyze the five-year overall survival. Chi-square test was applied to compare the local control rate and recurrence-free survival. Logistic regression analysis was used to determine the correlation between all factors and the local control rate. Results:For all patients, the five-year local control rate, five-year recurrence-free survival rate, and five-year overall survival rate were 71.49%, 69.61%, and 76.10%respectively. The five-year local control ratio (81.96%vs. 61.90%), five-year recurrence-free surviv-al (78.69%vs. 59.52%), and five-year overall survival (88.12%vs. 68.50%) were significantly improved in Group Two compared with Group One. The logistic regression analysis showed that the therapeutic method, T staging, as well as pN(+) neck and tumor differentia-tion were significantly correlated to the five-year local control rate and five-year recurrence-free survival (P<0.01). Cox regression anal-ysis showed that therapeutic method, T stage, as well as pN(+) neck and tumor differentiation were significantly correlated to the five-year overall survival (P<0.01). Conclusion:Post-operative radio-chemotherapy can improve the local control and overall survival rates. This therapeutic method is applicable to patients with T3-4 tumors, as well as pN(+) neck and middle-low differentiation.

BACKGROUND: After the damage of central nervous system, F-waves of electromyography is the valuable way for detecting tendon reflex and muscular tension below injured segment. The increase of spasm, stiffness and muscular tension induced by upper motor neuron injury can revoke change of F-waves.However, change of F-waves after spinal injury, and relationship between Fwaves and spasm of lower limb after injury are still unclear at present.OBJECTIVE: To analyze the correlation of minimal latency, occurrence rate and every index of dispersion-time degree of F-waves with post-injured spinal cord spasm in patients with spinal injury.DESIGN: Case-control observation.SETTING: Department of Rehabilitative Medicine, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: Totally 29 patients with traumatic spinal cord injury,who were hospitalized at Department of Rehabilitative Medicine, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology between June 2002 and March 2004, were selected as spinal injury group. Another 29 normal healthy volunteers were enrolled as normal control group in the same period. METHODS: Spasm level of both lower extremities in patients with spinal injury was graded with Ashworth scale to assess flexion of both coax, flexion of knee joint and Ashworth grade of dorsiflexion of ankle. F-waves was detected with Kepoint1.5 type EMG instrument produced by Denmark.Minimal latency, maximal latency and occurrence rate of F-waves of tibial nerve of both lower extremities were recorded. The discrete-time degree (difference value of maximal latency of F-waves and minimal latency of Fwaves) and mean occurrence rate of F-waves were calculated.MAIN OUTCOME MEASURES: The difference of each index between patients with spinal injury and normal persons was compared and the correlation of spasm with discrete-time degree, occurrence rate and minimal latency of F-waves in patients with spinal injury was analyzed.RESULTS: A total of 29 patients and 29 normal persons were involved in the result analysis. ①The discrete-time degree of F-waves in patients with spinal injury was higher than that in the normal persons, which had significant difference [(9.2±1.9), (6.7±1.0) ms, P ＜ 0.000 1]. ②The occurrence rate of F-waves in patients with spinal injury was lower than that in normal persons, which had significant difference [(84.5±6.2)%, (89.5 ±5.7)%, P ＜ 0.05]. ③The minimal latency of F-waves in patients with spinal injury was higher than that in normal persons, which had insignificant difference ( P ＞ 0.05). ④The discrete-time degree of F-waves in patients with spinal injury had positive correlation linearly with score of spasm Ashworth (r=0.790 31, P＜ 0.000 1). The occurrence rate of Fwaves in patients with spinal injury had positive correlation linearly with score of spasm Ashworth (r=0.742 03, P ＜ 0.000 1 ). The minimal latency of F-waves in patients with spinal injury had insignificant correlation with score of spasm Ashworth (r=0.081 68, P ＞ 0.05).CONCLUSION: The discrete-time degree and occurrence rate of F-waves can be used as sensitive index to evaluate electrophysiology in patients with spinal injury so as to assess the level of spasm in patients with spinal injury.

Crocetin, a naturally occurring carotenoid, possesses antioxidant and antiatherosclerotic properties, of which the underlying mechanism remains unclear. In the present study, we examined the effects of crocetin (0.1, 1, 10 μmol·L(-1)) on angiotensin II (Ang II, 0.1 μmol·L(-1)) induced expression of vascular cell adhesion molecule-1 (VCAM-1) in human umbilical vein endothelial cells (HUVECs) and monocyte-endothelial cell adhesion. The effects of crocetin on the activation of nuclear factor kappa B (NF-κB) and intracellular reactive oxygen species (ROS) were also observed. The results demonstrated that crocetin notably suppressed Ang II induced NF-κB activation (P<0.01) and VCAM-1 expression (P<0.05, P<0.01) in HUVECs, accompanied by a markedly reduced monocyte-endothelial cell adhesion (P<0.05, P<0.01). In addition, preincubation with crocetin resulted in a significant enhancement of cellular antioxidant capacity (P<0.05, P<0.01), while Ang II induced intracellular ROS decreased markedly (P<0.05, P<0.01). These results indicated that crocetin was capable of suppressing Ang II induced VCAM-1 expression and monocyte-endothelial cell adhesion by suppression of NF-κB activation, which might be derived from the enhancement of antioxidant capacity and subsequent reduction of intracellular ROS.

Objective:To study the expression of coxsackievirus group B3 gene fragment encoding VP1 in procaryon and to explore its application.Methods:Stablie expression of VP1 gene of CVB3 in E.coli was obtained.The expressed protein was purified by NAT chromatography and its immunoactivity was identified by indirect ELISA.Results:The expressed product of VP1,similar to native protein antigen of CVB3,could strong bind with the mouse's antibody serum against CVB3(polyclonal antibody).Irrelevant monoclonal antibody as contrast presents negative activity. Using the expressed VP1 product,we have had a special IgM ELISA for the patient's serum of the clinical acute viral myocarditis.The result was same with the cellular protein antigens of the tissue-cultivated CVB3.Conclusion:The protein antigen CVB3-VP1 which is obtained by the method of gene engineering has character of high product, and its immunoactivity after being purified was basically unchanged. At present, this kind of antigen is difficult to be obtained from the viral cullture medium and a potent hazard for being infected by this virus may take place in such manipulateion. By the method of gene engineering we can obtain antigenic VP1 of CVB3 and use as immuneogen for the detection of serum antibody,by which to provide reliable test reference for the early-stage diagnosis and clinical therapy of the acute myocarditis.
