Distribution channel of Chinese herbal medicines has been changing. From Han to Ming Dynasty, Chinese herbal medicine were mainly trafficked to urban by dealers or farmers; From the Ming Dynasty to the foundation of new China, distribution channels are primarily intermediated with township "bazaar" and national distribution center with fixed place and regularly trading hours. In the planned economy period, the state-owned herbal medicine company was the sole medium with monopoly nature. From the mid1980s to the end of last century, planned economy and market economy have been co-existing. Stepping into 21st century, producing area highlighted in the distribution channels. Presence or absence and rise or fall of different types of distribution market went throughout the changing process of distribution channels, which became an important clue. Changes were motivated by economical consideration of channel subject, which originated from commodity characteristic and social environment changes.

OBJECTIVETo explore the features of various mediastinal lymphadenopathies using computed tomography perfusion (CTP).

METHODSCTP parameters (CTPs) of the selected mediastinal nodes from 59 patients with pathology-proven malignant lymph nodes and of those from 29 patients with clinically diagnosed or pathology-proven inflammatory lymphadenopathies were collected. Patients were divided into subgroups by etiology and phase of primary disease, including different pathological malignant nodes and diverse inflammatory nodes. CTPs were defined as blood flow (BF), blood volume (BV), mean transit time (MTT), permeability (PMB), and time to peak (TTP). Differences of CTPs were compared between malignant and benign nodes, and among subgroups, respectively.

RESULTSIn the mediastinum, no significant differences of CTPs were found between malignant and benign groups (all P>0.05), the same for subgroups of malignant nodes (all P>0.05). Acute lymphadenitis had higher BF and BV than chronic inflammatory, lymphoid tuberculosis, sarcoidosis and malignant nodes. The BF of malignant nodes was markedly slower than that of acute lymphadenitis (P=0.01), but faster than chronic inflammatory nodes (P=0.04) and sarcoidosis (P=0.03), with no significant difference compared with lymphoid tuberculosis. Pneumonia-complicated lymphoid tuberculosis showed the longest MTT while sarcoidosis displayed the shortest MTT, and inflammatory nodes, lymphoid tuberculosis without complicated pneumonia and malignant nodes had moderate MTT.

CONCLUSIONCTPs show promising potential in distinguishing various lymphadenopathies in the mediastinum, but more studies are needed to improve their specificity.

Objective To investigate the effect of hyperbaric oxygen(HBO)on p38 MAPK signal pathway in neuropathic pain,and explore its mechanism. Methods The experiment was divided into two parts with thirty SD rats in each part. Each part was then randomly divided into 3 groups:sham operation group(S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group),with 10 rats in each group. Part one:Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. Phosphorylative p38 was detected by Western blot method and the P2X4 receptor was detected by immunohistochemistry method on the 28th day. Part two:All the rats were treated with SB203580. Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. P2X4 receptor was detected by immunohistochem?istry method on the 28th day. Results CCI and HBO groups were significantly lower than S group in pain?related behaviors(P<0.05). CCI group was significantly lower than that in HBO group(P<0.05). The content of phosphorylative p38 and P2X4 receptor in CCI and HBO group were increased(P<0.05),and the expression of phosphorylative p38 and P2X4 in CCI group was significantly increased than that in HBO group (P<0.05). When p38 MAPK was inhibited,pain?related behavior in HBO and CCI group increased significantly than the pain?related behavior of HBO and CCI group in Part 1(P<0.05). But the difference between group CCI and HBO was not significant(P>0.05). Though the expression of P2X4 receptor in CCI group and HBO group was significantly higher than that in S group(P<0.05),the difference between group CCI and HBO was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can affect the expression of p38 MAPK through P2X4 receptor in rats of neuropathic pain.

0.05). The average and maximal heart rates of subjects in bench stepping during exercise were higher than those in home stepping (P 0.05), however, the correlation between the direct calculation and home stepping was high (r=0.46, P 0.05).③The correlation between two step experiments for male students was high (r=0.73, P 0.05), however, the difference for female students was significant (P 0.05). CONCLUSION: Two indirect test protocols need further improvements, but home step is more appropriate for a large sample of constitution assessment by comparison of measurement efficiency and precision.

Objective　To examine the left ventricular diastolic function of patients with coronary artery diseases by noninvasive echocardiography and invasive coronary angiography.Methods　Mitral and pulmonary venous Doppler signals were recorded by the continuous wave Doppler technique in 62 patients, both coronary angiography and left ventricle pressure were measured. Patients were divided into normal and abnormal groups based on coronary angiography.Results　Left ventricular end diastolic pressure (LVEDP) (17.6 mm Hg vs 13.2 mm Hg,P<0.05),the left ventricular negative Δp/Δt before atria contraction ［-(224.63±52.18),-(87.81±24.41),P<0.05］,and the elevated value of left ventricular pressure derived from atria contraction ［(6.66±0.92)mm Hg vs (0.96±1.87)mm Hg,P=0.0094］ in abnormal group were more than those in the normal. The ratio of slope in pulmonary vein and mitral A wave peak was less in normal group than that in the abnormal (5.10±0.31 vs 4.12±0.20,P＝0.0106). But the isovolume relaxation parameters had no differences between the two groups.Conclusions　Coronary arter ischemia is an important cause of left ventricular impaired relaxation aggravation and stiffness, the diastolic abnormalities existed in the whole diastolic duration. Except ischemia, other factors also could cause relaxation disfuction and even elevate the LVEDP.

Objective To investigate whether hyperbaric oxygen(HBO)affected neuropathic pain through autophagy and verify the HBO effect. Methods A total of 60 male SD rats were selected for the study and randomly divided into 4 groups:control group(C group),sham operation group (S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group). LC3Ⅱand P62 were determined by Western blot method and the autophagy was detected by electron microscopy on the 7th day. Results CCI and HBO groups were significantly higher than C and S group in Western blot(P<0.05). There was no difference between group C and group S(P>0.05). The expression of LC3Ⅱin HBO group was significantly higher than that in CCI group(P<0.05). And the expression of P62 in CCI group was significantly higher than that in HBO group(P<0.05). The autophagy in CCI and HBO group were significantly increased comparing to the C and S groups(P<0.05). However,the difference be?tween group C and S was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can induce autophagy for anti?neuropathic pain.

OBJECTIVE: To investigate the molecular mechanism of Huanglian Jiedu Decoction (HLJDD), a traditional Chinese compound herbal medicine, in treating type 2 diabetes mellitus (T2DM) by observing its effects on glucose transporter 4 (GLUT4) protein expression and translocation in adipose and skeletal muscle tissues of rats with T2DM. METHODS: T2DM was induced in rats by intravenous injection of a small dose of streptozotocin (STZ, 30 mg/kg) plus high fat and high caloric laboratory chow. Then animals were divided into untreated group, aspirin-treated group and HLJDD-treated group. Normal rats fed with common chow were designated as normal control group. Ten weeks later, the oral glucose tolerance test (OGTT) was performed in all animals, and the changes of murine body weight, fasting blood glucose (FBG), fasting serum insulin (FINS) and the expression of GLUT4 protein in skeletal muscle and adipose tissues before and after insulin treatment were routinely determined. RESULTS: Compared with the untreated group, the result of OGTT of HLJDD-treated group was improved. The levels of the body weight and FBG were decreased, while the GLUT4 protein expression and translocation were elevated obviously. CONCLUSION: It is suggested by the present results that the therapeutic effects of HLJDD on T2DM might be related to its ability of increasing GLUT4 protein expression and translocation in adipose and skeletal muscle tissues of T2DM rats.
