Objective To investigate the effects of different magnitudes of mechanical strain on proliferation and alkaline phosphatase (ALP) activity in mouse osteoblast-like cells (MC3T3-E1). Methods MC3T3-E1 cells were subjected to 0%, 6%, 12%, 18% elongation for 24h and 48h by using multi-passage cell stress loading system respectively. MTT colorimetric method was used to assess the proliferation of the cell, ALP activity was detected by ALP assay kit. Results The proliferation of MC3T3-E1 cells was increased significantly 24h and 48h after mechanical strain treatment concomitant with increasing stretching force (P

OBJECTIVETo observe the effect of Modified Yiqi Chutan Recipe (MYCR) on blood flow perfusion in treating mid-late stage non-small cell lung cancer (NSCLC) patients by using multislice CT perfusion (CTP) , and to assess the relationship between each CTP parameter and the prognosis as well.

METHODSTotally 87 mid-late stage NSCLC patients were randomly assigned to the treatment group (44 cases, Shenyi Capsule + MYCR +chemotherapy) and the control group (43 cases, chemotherapy alone) in the ratio of 1:1. And 21 days consisted of 1 therapeutic course, 4 courses in total. All of them underwent CTP of primary tumor and routine thoracic CT examination (plain CT and enhancement CT) 3 times (before therapy, after 2 and 4 cycles). CT findings were analyzed for tumor size and perfusion parameters [blood flow (BF), blood volume (BV), permeability surface (PS), mean transit time (MTT), and time to peak (TP) before and after treatment, and relationship between perfusion parameters and prognosis was also assessed.

RESULTSIn 87 cases, 7 dropped out and 80 cases were available, 40 in the treatment group and 40 in the control group. (1) The relief rate was 47.5% (19/40) and the total stable rate was 77.5% (31/40) in the treatment group, and they were 40.0% (16/40) and 65.0% (26/40) in the control group, with no statistical difference between the two groups (χ² = 0.672, 1.227; P > 0.05). (2) Compared with before treatment group in the same group, BF and PS decreased, and MTT increased in the two groups after 2 and 4 courses (P < 0.05); BE and PS decreased, and MTT increased in the control group after 2 courses (P < 0.05). Compared with the control group after 4 courses, BE decreased more significantly in the treatment group (P < 0.05). (3) After 4 courses, all patients were assigned to the remission group (35 cases) and the non-remission group (45 cases) according to the RECIST standard. Compared with before treatment in the same group, BF, BF, and PS all decreased, and MTT increased in the remission group after treatment (all P < 0.05); BF increased in the non-remission group after treatment (P < 0.05). (4) All patients were assigned to the BE increase group (34 cases) and the BE decrease group (46 cases) according to changed BE values after treatment. Results showed the mean survival rate was 246 days in the BF increase group (the 1-year accumulative survival rate being 13.0%) and 387 days in the BE decrease group (the 1-year accumulative survival rate being 53.1%). The life span was prolonged and the 1-year accumulative survival rate was elevated in the BE increase group, with statistical difference as compared with the BE decrease group (χ² = 19.057, P < 0.01).

CONCLUSIONSShenyi Capsule plus MYCR could reduce BE in mid-late stage NSCLC patients , improve vascular permeability, showing better synergistic effect with chemotherapy. CTP could not only reflect the change of tumor size, but also reflect vascular function of the tumor. Meanwhile, changes of CTP parameters were closely associated with prognosis. Patients with post-treatment decreased BE value had better prognosis and longer life span.

0.05).In the 16 cases,17 retroperitoneal laparoscopic excisions of pheochromocytoma were successful,only 1 was converted to open surgery due to intraoperative bleeding. The mean operative time was 85?31 (range,45 to 150) min in laparoscopic surgery group vs 155?39 (90 to 240) in open surgery group (P

【Objective】 To assay the naringenin content in different medicinal materials of Exocarpium Citri Grandis (ECG). 【Methods】 High performance liquid chromatography (HPLC) was applied to determine the naringenin content in different medicinal materials of ECG. The chromatographic conditions were: gradient elution being performed with methanol as mobile phase A and water - acetic acid (61: 4) as mobile phase B, flowing rate being 1.0 mL/min; detecting wavelength at 283 nm. 【Results】 In the rage of 0.088～0.880 ?g, naringenin showed a good linearity with the chromatographic peak area, r=0.9999, average recovery rate was 95.49% and RSD=2.00% (n=5). The naringenin content in 23 different samples of ECG was in the range of 0.1～1.0 mg?g~(-1). 【Conclusion】 It is the first time to establish the HPLC method for the determination of naringenin content in ECG and the method is accurate and reproducible. Naringenin content in varieties of ECG is stable and the difference of naringenin content between Citrus grandis Osbeck. Var. tomentosa Hort. and Citrus grandis (L.) Osbeck is not significant.

Objective To evaluate the performance and feasibility of sentinel node biopsy(SNB) in male breast cancer patients using Methylthioninium Chloride Injection.Methods At the First Affiliated Hospital of Zhengzhou University,there are 11 patients in group from March 2010 to December 2014.The clinical stage was cT1-T2N0M0.All patients using Methylthioninium Chloride Injection as the tracer.11 patients are given with sentinel lymph node biopsy,while given the axillary lymph node dissection.Results In 11 cases of male breast cancer patients,10 cases obtained the sentinel lymph nodes,the detection rate was 90.9％ (10/11).The sentinel lymph node is in 1-3,the average is 1.7 gold.Non sentinel lymph nodes are in 8-14,the average is 10.5 gold.The coincidence rate is 90.0％ The sensitivity is 100％ and The precision is 60％.Conclusions Sentinel lymph node biopsy can accurately predict the metastasis of axillary lymph node of breast cancer in male patients.
