OBJECTIVETo observe the effect of Qianliean Pill (QP) on inflammatory factors such as IL-1β, IL-10, and tumor necrosis factor α (TNF-α) in chronic nonbacterial prostatitis (CNP) model rats, and to explore its therapeutic mechanism.

METHODSCNP rat model was established by castration and estradiol benzoate injection. Totally 50 rats were randomly divided into 5 groups, i.e., the model group, the positive medicine group, the high dose QP group, the medium dose QP group, and the low dose QP group, 10 in each group. Besides, 10 normal rats were recruited as a normal control group. Since the 8th day of castration, Pulean Tablet (PT) at 10. 80 g/kg was administered to rats in the positive medicine group by gastrogavage. QP at 11.00, 5.50, and 2.75 g/kg was administered to rats in high, medium, and low dose QP groups by gastrogavage. Distilled water at 2 mL/100 g was administered to rats in the model group and the normal control group by gastrogavage, once daily for 30 successive days. After 30 days of medication all rats were sacrificed and their prostate tissues were extracted. The prostatic index was calculated. Pathological changes of rat prostate were observed under light microscope. Meanwhile, levels of IL-1β, IL-10, and TNF-α were detected using enzyme linked immunosorbent assay.

RESULTSCompared with the normal control group, the prostate index obviously decreased, levels of IL-1β, TNF-α, and IL-10 in the prostate tissue significantly increased in the model group (P < 0.01). Compared with the model group, the prostate index obviously decreased in high and medium dose QP groups, and the positive medicine group (P < 0.01); levels of IL-1β, TNF-α, and IL-10 obviously decreased in each QP group and the positive medicine group (P < 0.01). Compared with the positive medicine group, the TNF-α level decreased more obviously in the high dose QP group (P < 0.05). Compared with the normal control group, inflammatory reactions occurred obviously in rats' prostate of the model group. Compared with the model group, inflammatory reactions were milder in rats' prostate of each QP group and the positive medicine group, and their degrees were improved to some extent.

CONCLUSIONQP could treat CNP, which might be achieved by regulating local immune state of the prostate, relieving inflammatory reactions of the prostate, and lowering levels of IL-β, TNF-α, and IL-10 in the prostate tissue.

Meridian essence has been investigated through anatomy, electrophysiology, biophysics, and biochemistry. Various hypotheses of meridian essence exist, but no hypothesis can truly reflect the internal character of Chinese medicine (CM). The research of meridian essence requires a holistic viewpoint and innovative awareness. Initially, any hypothesis regarding meridian essence should begin with observation of the human body. Secondly, the research should arise from the meridians' physical functions and pathological changes, so as to maintain the fundamental nature of the meridians themselves. Thirdly, the research should be based upon the theory of CM, yet coupled with the integration of modern techniques to deepen our understanding of the scientific contents of meridians. Fourthly, theoretical research should be combined closely with clinical practice, in order to test the achievements in actual conditions. Lastly, more attention should be given to negative results in studies to more accurately discover the real essence of meridians.

Objective　To explore the risk factors and indications for perioperative tracheostomy in patients with myasthenia gravis. Methods　A total of 174 patients with myasthenia gravis undergoing thymectomy were reviewed retrospectively between April 1980 and August 1999. Perioperative tracheostomy was performed on 44(25.3%) cases. Myasthenic or cholinergic crisis happened in 38 cases (21.8%). The relationship of the crisis incidence and Osserman classification, state of illness, present of thymoma, preoperative pulmoary function and the dose of anticholinergic agents given preoperatively were analyzed. At the same time the indications of perioperative tracheostomy were discussed. Results　The highest incidence of myasthenic or cholinergic crisis and perioperative tracheostomy were found in cases with long history of the disease, high dose of anticholinergic agents administration, Osserman classification over stageⅡb, with infiltrated thymoma, and preoperative pulmoary function impairment. Conclusion Perioperative tracheostomy and artificial ventilation are most important approaches when myasthenic or cholinergic crisis after thymectomy appeared. But the indications for postoperative prophylactic tracheostomy and artificial ventilation must be strictly selected.

Currently,the quick development of information technology is enriching the traditional teaching.As a new form of teaching resource,a micro-lecture focused on a specific topic is a good combination of information technology and traditional teaching.It not only increases the vividness and visualization of teaching,but also boosts the learning interest of students in the course.What's more,it helps to show an integral time-consuming experiment in 5-10 minutes'micro-vedio,which broadens the contents of the course and offers convenience of self-teaching for students.In this article,we took the example of micro-lecture"Western blot"in the course of immunologic technology to post-graduates in Shanghai University of Traditional Chinese Medicine to clarify the advantages and the procedures of a typical micro-lecture,and to discuss about it.The experience achieved from the construction of this micro-lecture may offer a new idea of modern information education reform.

OBJECTIVETo observe the mechanism of the optimized traditional acupuncture prescription for accouchement on cervical ripening based on the molecular biology by observing related indices of cervical ripening in late-stage pregnant rats.

METHODSTwenty initial pregnant Wistar rats were randomly divided into an electroacupuncture (EA) group (n = 10) and a model group (n = 10), and other 10 non-pregnancy female rats with same lot were selected as a blank control group. EA group was treated with the optimized traditional acupuncture prescription for accouchement on the 20th day of pregnant, which performed EA at bilateral "Hegu" (LI 4) for 20 min and then at bilateral "Sanyinjiao" (SP 6) for 5 min with 2 Hz/50 Hz sparse-dense wave, while the other groups without acupuncture intervention. The contents of matrix metalloproteinase 9 (MMP-9) and interleukin 8 (IL-8) in cervix tissue were detected by ELISA method.

RESULTSCompared with the blank control group, the contents of MMP-9 and IL-8 in the model group were increased significantly (both P < 0.01). Compared with the model group, the contents of MMP-9 and IL-8 in the EA group were increased significantly (P < or = 0.05).

CONCLUSIONOptimized traditional acupuncture prescription for accouchement can increase the contents of MMP-9 and IL-8 in cervix tissue of late-stage pregnant rats so as to promote cervical ripening, and the mechanism of EA in promoting cervical ripening is explained from the perspective of molecular biology.

In order to construct RGD-mSAK mutant with reduced immunogenicity, and identify its biological activity after purification, mSAK gene fragment was amplified by over-lapping extension PCR. Then the gene was inserted into the prokaryotic expression vector pBV220 with P(R)P(L) promoters after confirmed by DNA sequencing; the expression plasmid pBV220-RGD-mSAK was constructed, and then was transformed into E. coli. DH5alpha. After temperature induction, the mutant Staphylokinase was over-expressed and much of protein was in the supernate of lysate, which is over 50% of total protein in the host. The protein was isolated and purified in Q-Sepharose FF, Sephacryl S-200 and SP, high purity protein was obtained and its purity was over 98%. The thrombolysis activity of the RGD-mSAK protein is 1.68 x 10(5) u/mg by fibrin plate assay, which is slightly higher than that of the wild-type, and antiserum titers raised against this protein in guinea pigs were much lower than those of wild-type SAK, determined by ELISA. In anti-platelets aggregation assay in vitro, the RGD-mSAK protein has obvious inhibition activity of platelet aggregation in low concentration comparing to the control group and wild-type SAK group. So the RGD-mSAK protein is a low immunogenicity, bi-function molecular with both thrombolysis activity and anti-embolism activity. It provided the basis for further research of RGD-SAK.

OBJECTIVETo compare the incidence of emotional disorder in patients with acute or stable coronary heart disease.

METHODSA total of 298 patients with suspected coronary heart disease (CHD) were designed into three groups based on of coronary angiography results: acute coronary syndrome (ACS, n = 128), stable angina pectoris (SAP, n = 108) and non-CHD (n = 62). All patients were evaluated by Zung Self-rating Depression Scale (SDS), Zung Self-rating Anxiety Scale(SAS) and Hamilton Depression Rating Scale (HRSD) for depression and anxiety before coronary angiography (CAG), 3 days after CAG, and 1 day before discharge.

RESULTSIncidences of depression and anxiety were significantly higher the ACS group (65.6%and 78.9% before CAG; 60.9% and 70.3% 3 days post CAG; 45.3%and 64.8% before discharge) compared patients with SAP (18.5% and 26.9% before CAG; 17.6% and 28.7% 3 days post CAG; 15.7% and 26.9% before discharge, all P < 0.05 vs. ACS) and non-CHD patients (32.3% and 25.8% before CAG; 27.4% and 24.2% 3 days post CAG; 29.0% and 30.6% before discharge, all P < 0.05 vs. ACS) while the depression and anxiety incidences were similar between patients with SAP and non-CHD in this cohort (P > 0.05).

CONCLUSIONEmotional disorder is common in patients with suspected heart diseases, especially in patients with ACS. Psychological distress of patients with suspected heart disease should be evaluated and treated.
