OBJECTIVETo study the effect of Qinghuang Powder (QHP) combined Chinese herbs for Pi-strengthening and Shen-reinforcing (CHPSSR) on hypoxia-inducible factor 1alpha (HIF-1alpha) in bone marrow mononuclear cells of myelodysplastic syndrome (MDS) patients.

METHODSChanges of HIF-1alpha in bone marrow mononuclear cells of MDS patients were detected in 25 MDS patients treated by QHP combined CHPSSR using flow cytometry. Meanwhile, 13 healthy subjects were recruited as the control group. Changes HIF-1alpha levels in various serial bone marrow mononuclear cells were detected.

RESULTS(1) Among the 25 patients in the treatment group, there were 19 patients effective and 6 patients ineffective, with the total effective rate being 76%. (2) Compared with before treatment, levels of peripheral blood WBC, Hb, PLT, and ANC significantly increased in the treatment group after treatment, showing statistical difference (P < 0.05, P < 0.01). (3) Compared with before treatment, the HIF-1alpha mean fluorescence intensity was enhanced in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of the treatment group after treatment (P < 0.05, P < 0.01). Compared with the control group, the HIF-1alpha mean fluorescence intensity was weakened in bone marrow lymphocytes, monocytes, and nucleated red blood cells of the treatment group before treatment; while it was obviously enhanced in granulocytes (P < 0.01). But after treatment the HIF-1alpha mean fluorescence intensity increased more in the granulocytes of the treatment group than in those of the control group (P < 0.01), but there was no statistical difference in bone marrow lymphocytes, monocytes, or nucleated red blood cells.

CONCLUSIONQHP combined CHPSSR could improve HIF-1alpha levels in bone marrow lymphocytes, monocytes, granulocytes, and nucleated red blood cells of MDS patients, thus improving Hb levels of MDS patients, and improving their anemia and correlated symptoms.

Objective To establish the in vivo models of adriamycin(ADR)-induced cardiotoxicity in rabbits, investigate the protective effect of oxymatrine (OMT) on ADR-induced cardiotoxicity, and explore the possible mechanism. Methods Twenty-six rabbits were randomly divided into ADR group (n=8, 2 mg/kg ADR), OMT group (n=5, 10 mg/kg OMT), ADR + OMT group (n=8, 10 mg/kg OMT was injected 30 min before ADR injection) and saline group (n=5, same quantity of normal saline), and rabbits in each group were infused with medicine or normal saline through ear marginal vein once a week for 8 weeks. The apoptosis of myocardial cells was detected by TUNEL methods, and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was determined. Results After treatment, the body weight of ADR group was significantly lower than that of the other groups(P < 0.05), the activity of SOD and GSH-Px significantly decreased and the apoptosis index (AI) was significantly higher than that of the other groups(P <0.01). There were similar while minor changes in ADR + OMT group. There was no significant adverse effects in OMT group. Conclusion OMT protects heart from adriamycin-induced injury in rabbits, which may relate to the decrease in level of antioxidant and apoptosis of myocardial cells.

The 1.23 kb DNA fragment encoding the early protein EP0 of pseudorabies virus (PRV) Ea strain was amplified by PCR technique and cloned into pBluescriptII sk+.Three sequencing plasmids containing the partial fragment of the EP0 gene were constructed and the sequences were obtained by Sanger's sequencing technique. Compared with PRV InFh strain, there were multipile site-mutations and a deleted-mutation in the EP0 gene of PRV strain Ea，and the diversity of amino acid residues also existed.Then, the EP0 gene was inserted into an expression vector, pET-28a, fused into the downstream of the 6ΧHis-Tag in frame, to yield the expression plasmid pETEP0. After induction by IPTG, a high expression of fusion protein was obtained, SDS-PAGE analysis and Western blotting showed that the fusion protein was 62kD and the protein was specific to antisera against PRV Ea strain. This indicated that the EP0 gene be expressed in BL21(DE3) and the expression products have immuno-genicity.

Objective:To evaluate the accuracy of two-dimensional ultrasound(2D-US), three-dimensional volume ultrasound (3D-US) and ultrasound strain elastography (USE) in the measurement of preoperative tumor size of breast cancer and its influencing factors.Methods:A total of 101 patients with breast cancer in Nanfang Hospital of Southern Medical University from April to November 2016 were recruited in this study. The maximum diameter of the lesion was examined by 2D-US 3D-US and USE before core needle biopsy or surgery biopsy. The Bland-Altman analysis and intraclass correlation coefficient (ICC) were used to analyze the consistency between the ultrasonic technique measurements and the pathological measurements of postoperative lesion. Chi-square test or Fisher exact test was used to analyze whether the accuracy of three imaging techniques was affected by different clinical pathologic factors and imaging characteristics.Results:3D-US showed better agreement with histology than 2D-US and USE, with a higher ICC (ICC 3D-US=0.90>ICC 2D-US=0.81>ICC SUE=0.78) and low variation. In 3D-US, the accuracy rate of the age >40 years old group was higher than ≤40 years old group. In 2D-US, the measurement accuracy of invasive ductal carcinoma (IDC) without intraductal carcinoma in situ (DCIS) group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. The long diameter of lesion ≤2 cm group was more accurate than >2 cm group, IDC group was more accurate than invasive lobular carcinoma(ILC) group. In USE, the measurement accuracy of IDC without DCIS group was higher than DCIS with DCIS group, non-microcalcifications group was more accurate than microcalcifications group. All the differences mentioned above were statistically significant(all P<0.05). Conclusions:For accurate measurement of the size of breast cancer lesions, 3D-US is the best, which is least affected by clinicopathological factors and imaging features, followed by 2D-US and USE. This has certain significance for clinically determining the extent of breast cancer lesions.

Objective To discuss the serum value of human epididymis protein 4(HE4) in the diagnosis of lung can-cer and to analyse the serum levels of HE4 in different pathological types and TNM staging of lung cancer patients. Meth-ods Forty-seven patients with lung cancer and thirty-one healthy controls were selected to join this study. According to various pathological types and TNM staging, the selected lung cancer patients were divided into different subgroups under the two categories. The serum HE4 levels were compared between subgroups. ROC curves of serum HE4 level and serum CEA level were drawn for the diagnosis of lung cancer with the pathological diagnosis as the golden standard. Results There was significantly higher level of serum HE4 in lung cancer group[(253.47±170.03) pmol/L] than that of healthy group [(84.09±51.03) pmol/L](t=5.365). There were no significant differences in serum levels of HE4 between different pathological subgroups of lung cancer patients [non-small cell carcinoma group (241.34±161.81) pmol/L vs small cell carcinoma group (293.5±198.76) pmol/L, t=0.847;squamous cell carcinoma group (304.29±287.61) pmol/L, adenocarcinoma group (224.39± 122.15) pmol/L and small cell carcinoma group F=0.969;and different TNM staging subgroups [ (stageⅠ~Ⅲgroup (255.27± 183.04) pmol/L vs stageⅣgroup (288.16±216.49) pmol/L, t=0.528]. Compared with ROC curves of serum HE4 and serum CEA,the area under the curve (AUC) of serum HE4 (0.902) was larger than that of serum CEA(0.765),( P>0.001). When the serum level of HE4 was 149.145 pmol/L, the sensitivity and specificity in the diagnosis of lung cancer were 72.3% and 90.3%. When the serum level of CEA was 4.685μg/L, the sensitivity and specificity in the diagnosis of lung cancer were 57.4%and 83.9%. Conclusion The serum level of HE4 is a sensitive and specific tumor marker in lung cancer. There are no significant differences in the serum levels of HE4 between different pathological types and different TNM staging in lung cancer patients. The detection of serum levels of HE4 are useful for the diagnosis of lung cancer.

Quantitative NMR (qNMR) is a technology based on the principle of NMR. This technology does not need the references of the determined components, which supplies a solution for the problem of reference scarcity in the quantitative analysis of traditional Chinese medicines. Moreover, this technology has the advantages of easy operation, non-destructiveness for the determined sample, high accuracy and repeatability, in comparison with HPLC, LC-MS and GC-MS. NMR technology has achieved quantum leap in sensitivity and accuracy with the development of NMR hardware. In addition, the choice of appropriate experimental parameters of the pre-treatment and measurement procedure as well as the post-acquisition processing is also important for obtaining high-quality and reproducible NMR spectra. This review summarizes the principle of qHNMR, the various experimental parameters affecting the accuracy and the precision of qHNMR, such as signal to noise ratio, relaxation delay, pulse width, acquisition time, window function, phase correction and baseline correction, and their corresponding optimized methods. Moreover, the application of qHNMR in the fields of quantitation of single or multi-components of traditional Chinese medicines, the purity detection of references, and the quality analysis of foods has been discussed. In addition, the existing questions and the future application prospects of qNMR in natural product areas are also presented.
