Prescription Research and Clinical Application of Yiguanjian / 中国实验方剂学杂志

By systematically sorting out the ancient medical books and modern clinical literature of Yiguanjian， the historical evolution of this formula， including its source， composition， origin， processing， dosage， preparation and usage， functions and indications， evolution of prescription meaning， is textual so as to clarify the historical evolution and clinical application of Yiguanjian. On the basis of fully considering the actual demand of development of famous classical formula preparation and the usage habit of modern clinical practice， the feasible development suggestions were put forward. Yiguanjian is composed of six herbs， which is derived from Yifang Jiedu (《医方絜度》) . It is an ancient book of traditional Chinese medicine edited by QIAN Min-jie in Qing dynasty. The original medicinal plants and medicinal parts of the formula were basically the same as those recorded in the 2020 edition of Chinese Pharmacopoeia. The raw products should be selected for decoction pieces and processed according to the methods recorded in the 2020 edition of Chinese Pharmacopoeia. The reference dose of the medicine in this formula is set out in Yifang Jiedu. According to dosage of one Qian（钱）=3.73 g， the dosages of Glehniae Radix， Ophiopogonis Radix and Angelicae Sinensis Radix were 5.60 g， the dosages of Lycii Fructus and Rehmanniae Radix were 11.19 g， the dosage of Toosendan Fructus was 7.46 g. These decoction pieces were boiled and warm decoction was taken. According to ancient medical records， the formula always has the effect of nourishing Yin and relieving Qi of liver. It is used to treat syndrome of stagnation of liver-Qi and deficiency of liver-Yin and kidney-Yin， which can be seen with pain in chest， stomach and flank， acerbity and vomiting， dry throat and mouth， red tongue， weak pulse or deficiency of string and hernia. Here， the source， processing and others of Yiguanjian were clarified， providing a literature reference for the development and application of this famous classical formula.

Analysis on anti-vascular inflammatory mechanism in vitro of total flavones from Artemisia anomala / 中国中药杂志

<p><b>OBJECTIVE</b>To study the impact of total flavones from Artemisia anomala (TFAS) on activation of macrophages, cell oxidative stress, auto-nitration of CuZn-SOD, platelet aggregation and isolated vascular tension.</p><p><b>METHOD</b>LPS and IFN-gamma induced activation of macrophages and oxidative stress in rats; H2O2 and nitrite induced auto-nitration of CuZn-SOD; ADP, AA and collagen induced platelet aggregation in vitro in mice; PE stimulates isolated vascular tension; nitrite content of macrophages was measured by Griess assay; MTT assay and FRAP assay was applied for cell viability and total cell antioxidant capacity; auto-nitration of CuZn-SOD was measured by Western blot and colorimetric methods; platelet aggregation was detected by turbidimetry; and aorta ring relaxation was recorded by isolated vascular function experience devices for rats.</p><p><b>RESULT</b>TFAS demonstrated dose dependence (25, 50, 100, 200 mg x L(-1)) on inhibiting induced macrophages NO production from generating, while increasing cell viability and total anti-oxidant capacity. Auto-nitration of CuZn-SOD was suppressed by TFAS in dose dependence (0.5, 5, 50 mg x L(-1)). TFAS showed an inhibitory effect on collagen-induced platelet aggregation at 50 mg x L(-1) and an endothelium-dependent relaxation effect on PE-induced vasoconstriction at 1 g x L(-1).</p><p><b>CONCLUSION</b>TFAS shows effect on anti-inflammation, anti-oxidation, anti-nitration, anti-platelet aggregation and vasodilatation in experiment in vitro, which may inhibit vascular inflammatory by regulating multiple target points. It is among material bases for promoting blood circulation and removing blood stasis.</p>

Expression of caspase apoptosis pathway genes mRNA in colorectal cancer and polyps / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate mRNA expression of caspase apoptosis pathway genes in colorectal cancer, polyps and normal mucosa.</p><p><b>METHODS</b>Nineteen patients with colorectal cancer, 86 patients with polyps and 10 normal controls were enrolled from 2008 to 2010. Fluorescence quantitative RT-PCR was performed to detect the mRNA expression of caspase apoptosis pathway genes (caspase-2,-3,-6,-7,-8,-9 and -10) in colorectal cancer, polyps and normal mucosa.</p><p><b>RESULT</b>There were no statistically significant differences of demographic characteristics between patients with colorectal cancer, patients with polyps and normal controls. Compared with normal control group, the mRNA expression of all selected genes except for caspase-3 were lower; however, the P values did not reach statistic significance. Highly positive correlations were observed between mRNA expression of all selected genes except caspase-9.</p><p><b>CONCLUSION</b>There are no significant changes in mRNA expression levels of caspase apoptosis pathway genes from normal mucosa to polyps to cancer. The mRNA expressions of most caspase pathway genes are highly correlated with each other.</p>

Association of miR-605 and miR-149 genetic polymorphisms with related risk factors of lung cancer susceptibility / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To explore association of miR-149 and miR-605 polymorphisms with other risk factors of lung cancer susceptibility among Chinese population.</p><p><b>METHODS</b>Two hundred and forty-four patients with lung cancer and 243 cancer-free controls matched by age and sex were enrolled from 2002 to 2008. Peripheral venous blood samples were collected from all subjects. Single nucleotide polymorphisms (SNPs) of miR-149 and miR-605 were genotyped by PCR-RFLP. Multiple-variable logistic regression model was used to assess the association of SNPs and cancer related risk factors for lung cancer.</p><p><b>RESULT</b>There was not significant association of SNPs of miR-149 and miR-605 with lung cancer. A marginal significance was observed while the males with at least one G allele of miR-605 had higher risk of lung cancer (OR=1.5, 95% CI:1.0-2.3) than those with AA genotype. Increased frequency of smoking was associated with lung cancer risk. Compared with no-smoker, the subjects with <20 and >20 cigarettes/day had higher risk of lung cancer: OR (95%CI)=1.7(1.0-3.0) for <20 cigarettes, OR (95%CI)=4.2(2.3-7.6) for >20 cigarettes. There was no interaction between two genes and smoking on lung cancer.</p><p><b>CONCLUSION</b>miR-149 polymorphisms may not affect lung cancer susceptibility. miR-605 gene mutant might be increase the risk of lung cancer among males. Cigarette smoking increased a risk of lung cancer, but there were not interactive effects between two gene and smoking on lung cancer.</p>
