Objective: To investigate the expression of molecular marker ABCG2 of stem cells and tumor angiogenesis-related gene products including vascular endothelial growth factor (VEGF), CD34 and very late antigen alfa-2 (VLA-2α) in human glioma-bearing nude mice and observe the patterns of angiogenesis in transplanted tumors by CD34-PAS double staining. Methods: The human glioma cells were subcutaneously transplanted in 30 nude mice. Six normal brain tissues were as controls. The hematoxylin and eosin staining and immunohistochemical examination were performed to determine the positive rate and the hot-spot of gene product expression. The patterns of angiogenesis were observed under light microscope. Results: The positive rates of ABCG2, VEGF, and VLA-2α expression were all 100% in transplanted tumors. The average percentage of positive cells was (3. 93 ± 1. 438)%, (34. 84 ± 6.212)% (30.33 ± 4.428)%, respectively. The value of micro-vascular density (MVD) labeled by CD34 averaged at 29. 78 ± 5.88. All the three microcirculation patterns, endothelium-dependent vessels, mosaic vessels and vasculogenic mimicry, were present in xenografted human glioma tissue samples. Conclusions: The ABCG2-overexpressed cells tended to be located close to blood vessels. VEGF and VLA-2α play an important role in angiogenesis of transplanted tumors in nude mice. There exist three different microcirculation patterns in high malignant transplanted tumors.

This paper is aimed to study the differences of allelopathic effects of Panax notoginseng under different allelopathic chemicals resources and selection of appropriate rotation crops. The additive main effects and multiplicative interaction ( AMMI) model had been used to evaluate the stability of allelopathic effects of P. notoginseng on the varieties of corn, wheat and rice properly. The model could use not only to evaluate the stability of non-regional trial data but also explore the interaction between the rotation crop genotypes and donor substances more efficiently. Meanwhile, correspondence analysis can be used in the AMMI to evaluate genotype stability and donor substances. Ejingza No. 1 (g6) had stronger allelopathic effects with high stability, but Yunrui No. 1 (g9) which was appropriate rotation crop genotype, had weaker allelopathic effects with high stability. These findings will aid in choosing appropriate rotation crops and establishing proper rotation system.

Objective To determine the dietary nutritional status of rural residents in Midwestern Shandong Province,in order to improve the dietary pattern and health status of them.Method 11 987 residents,from 10 273 households,were included in this study by multi-stage randomized cluster sampling in 8 counties located in Midwestern Shandong Province.Questionnaire of Food Frequency (QFF) was applied to collect the information about the amount and frequency of food consumed by the subjects in the past year.Results The average intake of cereal,vegetable,fruit,meat,egg,milk,bean,oil and salt per reference man per day was 553.9 g,310.6 g,58.2 g, 36.3 g,50.1 g,16.7 g,34.4 g,44.8 g and 12.3 g,respectively.The average intake of energy,carbohydrate,protein,fat and dietary fiber per reference man per day was 12 095.6 kJ,451.8 g,85.6 g,78.8 g and 18.7 g as well Cereal food provides 66.1% of total energy; however,the meat provides only 6.6% of that.Carbohydrate,protein and fat amount to around 63.2%,12.0% and 24.8% of total energy, respectively.24.0% of fat intake was from animal food,while 76% of that was from vegetable food.Conclusions The intake of energy, protein,fat was sufficient for these subjects;however,the intake of vegetable,fruit,bean and meat was lower than the dietary reference intake.Moreover,oil and salt intake in these subjects was much higher than Chinese Recommended Nutrient Intakes.Thus,the amelioration of dietary pattern in rural residents will be an important task for nutrition workers in rural area of Midwestern part of Shandong Province in the future.

OBJECTIVE: To share the process of analysis and intervene the adverse drug reaction (ADR) caused by octreotide, and to provide reference for the work mode of clinical pharmacist. METHODS: One case of hypoglycemia possibly caused by octreotide was discovered. The clinical pharmacist recommend the doctor to replace octreotide as somatostatin after a review of the relevant information and literatures. Then the clinical pharmacist investigated awareness of hypoglycemia ADR of octreotide among the ICU doctors, and introduced the ADR of octreotide and the difference between octreotide and somatostatin among them. RESULTS: After the intervention, the hypoglycemia was corrected and the patient was cured and clinical pharmacists' working mode was identified. CONCLUSION: Clinically, pharmacists should not only have good professional knowledge, but also master the ways and means of communication, in addition to assisting doctors monitoring of adverse drug reactions, also need to continue to explore the work mode.

OBJECTIVETo compare the efficacy difference in the treatment of chronic pelvic pain syndrome of Sev-damp-heat stagnation pattern between acupoint catgut embedding therapy and western medication.

METHODSenty cases were randomized into a catgut embedding group (40 cases) and a western medication group (30 cases) at the ratio of 4 : 3. In the catgut embedding group, the catgut embedding therapy was applied to Sanyinjiao (SP 6), Quchi (LI 11), Huiyin (CV 1), Zusanli (ST 36), Zhongji (CV 3), Shenshu (BL 23), etc. The treatment was given once every two weeks, the treatment for 4 weeks was as one session and totally 2 sessions were required. In the western medication group, tamsulosin hydrochloride capsules 0. 2 mg, oral administration, once a day, and Indometacin sustained release tablets, 75 mg, once a day, 3 tablets each time were prescribed. The symptom score of TCM, score of NIH Chronic Prostatitis Symptom Index (NIH-CPSI), lecithin body number in prostatic fluid, (SAS) score of Self-Rating Anxiety Scale and score of Self-Rating Depression Scale (SDS) were compared before and after treatment in the patients of the two groups. The efficacy was evaluated in the two groups.

RESULTS(1)The total effective rate was 91. 9% (34/37) in the catgutembedding group and was 86. 2% (25/29) in the western medication group. The efficacy in the catgutembedding group was better than that in the western medication group (P<0. 05). (2) The symptom score of TCM was all reduced significantly after treatment in the two groups (both P<0.01), and the result in the catgut embedding group was superior to the western medication group (6.42 +/-2. 81 vs 10. 99+/-3. 11 ,P<0. 01). (3) Lecithin body number was increased apparently in the two groups after treatment (both P<0.01), and the result in the catgut-embedding group was superior to the western medicine group (33.56+/-5.88 vs 29. 78+/-7. 06,P<0. 05). (4) Total score of NIH-CPSI, score of pain, score of SAS and score of SDS were all improved apparently after treatment in the two groups (all P<0. 01), and the results in the catgut embedding group were superior to the western medication group (P<0. 01, P<0. 05).

CONCLUSIONThe acupoint catgut embedding therapy achieves the superior efficacy on chronic pelvic pain syndrome of damp-heat stagnation pattern as compared with conventional western medicine. This therapy relieves clinical symptoms, improves the states of anxiety and depression and increases lecithin body number obviously.

OBJECTIVETo investigate the clinical significance of matrix metalloproteinase-9 (MMP-9) and tissue factor (TF) secreted by cultured monocyte-derived macrophages (HMDM) from patients with coronary heart disease (CHD) in vitro, and to evaluate the intervenient effect of puerarin (Pur) on them.

METHODSA total of 40 patients were enrolled, including 12 patients with acute myocardial infarction (AMI), 16 patients with unstable angina pectoris (UAP), 12 patients with stable angina pectoris (SAP). Besides, 8 healthy subjects with normal coronary arteriograph were set as controls. Monocytes acquired from their peripheral blood were incubated for 48 h and induced to differentiate into macrophages by phorbolester 12-myristate 13-acetate (PMA), the contents of MMP-9 and TF in supernatant were assayed, and the relationship of them with patients' age, risk factors of CHD and coronary artery lesion scores were analyzed. HMDMs randomly from selected 12 patients with acute coronary syndrome (ACS) were arranged for observing the intervenient effects of different concentrations of Pur on the levels and activity of MMP-9 and TF.

RESULTSThe levels of MMP-9 and TF in UAP and AMI patients were significantly higher than those in SAP patients and healthy subjects (P < 0.01), but no statistical correlation was found between levels of MMP-9 and TF with different CHD risk factors, as well as patients' age and coronary artery lesion scores. The levels and activity of MMP-9 and TF in the 12 ACS patients were significantly decreased in a dose-dependent manner after Pur intervention when compared with the controt group.

CONCLUSIONThe levels of MMP-9 and TF secreted in vitro by HMDM from CHD patients could be taken as indexes for evaluating patient's condition of ACS. Pur can inhibit the expression and the activity of MMP-9 and TF secreted by HMDM, stabilize the plaque and improve the vulnerability of blood to certain extent.
