The establishment of quality evaluation of traditional Chinese medicine system that not only accords with Chinese medicine function characteristics but also is recognized as international medical circles, is an arduous task in urgent need of solving the current modernization of traditional Chinese medicine in the process of internationalization. It is difficult to evaluate atraditional Chinese medicine by detection of single active components in traditional Chinesemedicinewiththe western medicine quality controlmethod due to the overall effects of traditional Chinese drugs, the components of the overall diversity, targets, and the complexity of the interaction between components of unpredictable make the Long-term since, domestic and foreign scholars continue to explore and put forward a series of quality evaluation of traditional Chinese medicine to promote the development of traditional Chinese medicine. This article summarized the related academic ideas and developments to, providea new thought and perspective for the quality control of traditional Chinese medicine.

Background and purpose:Tumor microenvironment plays an important role in the introduction of foreign factors that mediate tumor acquired resistance. The antitumor effects of many chemotherapeutic agents depend on the level of oxygen pressure (pO2) in tumor microenvironment. This study aimed to evaluate electron paramagnetic reso-nance (EPR)-based monitoring on an oxygen-enriched tumor microenvironment to increase chemotherapeutic sensitivity. Methods:MCF-7 cells were used to establish human breast cancer in nude mice. EPR was used to directly measure pO2 levelin vivo. Tumor tissues were collected, and mitochondrial activity was assayed on the basis of the kinetics of enzyme-catalyzed reactions. A laser Doppler monitor was used to detect regional blood flow. Tumor apoptotic rate was analyzed by flow cytometry.Results:The tumor volume decreased more evidently in the chemotherapy group with oxy-gen-enriched environment than that in the conventional chemotherapy group after the treatment was administered (P<0.01). After chemotherapy was completed, the apoptotic rate of tumor cells was significantly higher in the chemotherapy group with oxygen-enriched environment than that in the conventional chemotherapy group (P<0.001). This study examined the mechanism ofpO2 changes in tumor microenvironment: This was related to the change of the balance between the oxygen consumption and the regional blood flow in the tumor tissues after chemotherapy.Conclusion:Based on the characteristics ofpO2 changes in the tumor microenvironment after chemotherapy was completed, the selection of chemotherapy mode forthe treatment inpO2 peak time window improves the sensitivity of chemotherapy, which provides a new idea for individual-ized chemotherapy in clinical applications.

Objective To investigate the effect of the polymorphisms of multidrug resistance 1 (MDR1) C3435T and G2677T on Tacrolimus (Tac) individualized treatment and prognosis of grafts in the renal transplantation recipients (RTRs).Methods One hundred and twenty-seven RTRs who treated with Tac regimen and had a stable graft function were enrolled,and were divided into adjuvant treatment group and non-adjuvant treatment group according to whether given adjuvant drugs to raise Tac trough concentrations. MDR1 C3435T and G2677T SNPs were detected by using sequence specific primers PCR.Tac trough concentrations of whole blood were measured by using enzymelabeled immunosorbent assay.Tac concentration-to-dose ratio (C/D) standardized by body weight was compared according to the various genotypes and haplotypes of MDR1 C3435T and G2677TA SNPs.Results Adjuvant treatment group including 36 recipients had a higher frequency of C genotype of C3435T than un-adjuvant treatment group (68.05％ vs 48.35％,P ＜ 0.01 ). The frequency of G2677TA polymorphisms was of no significant difference between the two group recipients (P＞ 0.05).As to non-adjuvant treatment recipients,the mean Tac DD required and C/D were not significantly different among various polymorphisms of MDR1 G2677T/A and C3435T or various haplotypes (P＞0.05).During A follow-up period of 4 years,13 recipients suffered graft dysfunction in which 84.6％ (11/13) carried 3435C genotype (P＞0.05).Conclusion The frequency of MDR1 C3435T polymorphisms in RTRs is high in the recipients given adjuvant treatment to raise Tac concentrations.Recipients with 3435C genotype were prone to graft dysfunction.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.
