Objective To investigate the change ofpermeability surfaces (PS) of CTperfusion(CT-p) before chemotherapy and early period treatment with chemotherapy (the first cycle of chemotherapy) in advanced non-small cell lung cancer and explore the correlation with the efficacy of chemotherapy.Methods Eighty patients with advanced non-small cell lung cancer which confirmed by pathology were taken standardized treatment by first-line drug.All patients performed with the CT-p technique before chemotherapy and one cycle after chemotherapy.The efficacy was evaluated by RECIST after 4 cycles of chemotherapy,the patients were divided into complete remission (CR) + partial response (PR),stable (SD),development (PD) according to the results and the change of PS was compared among these groups before chemotherapy and after 1 cycle of chemotherapy.Results Seventy-four patients' values of PS were useful.The remission rate and the stability rate was 32.4％ (24/74) and 78.4％ (58/74) respectively after 4 cycles of chemotherapy.PS after 1 cycle of chemotherapy in CR +PR (24 cases) and SD (34 cases) was lower than that before chemotherapy (12.38 ± 1.86 vs.18.13 ± 2.45,13.24 ± 1.97 vs.17.93 ± 2.38),and there was significant difference (P ＜0.05).There was no obvious change in PS before chemotherapy and after 1 cycle of chemotherapy in PD (16 cases),and there was no significant difference(P＞ 0.05).Conclusions The value of PS which reflects the change of perfusion in tumor vessel at early chemotherapy and the prognosis of the non-small cell lung cancer.Use the change of PS to predict the prognosis of patients with chemotherapy.It could be the norm of calculating the curative effect of chemotherapy in non-small cell lung cancer.

Hepatocellular carcinoma (HCC) complicated by arterioportal shunt (APS) is commonly seen in clinical practice,with an incidence rate of 28.8％-63.2％.It is manifested as abdominal pain,diarrhea,and ascites and can also lead to serious complications of portal hypertension including gastrointestinal bleeding.Although there are various therapeutic methods,they tend to have poor clinical effects.APS is one of the most important causes of death in patients with HCC.This article introduces the etiology,typing,clinical manifestation,and therapies of HCC complicated by APS and points out that although there are various therapeutic methods for HCC complicated by APS,interventional treatment remains the most important method.The exploration of interventional treatment helps to improve patients' prognosis.

Mutual promotion, mutual assistance and mutual inhibition are commonly for the compatibility of Chinese herbs, but they are also existed among the acupoints. In the paper, the relevant literature on acupoint, compatibility was collected and the mutual promotion, mutual assistance and mutual inhibition relationships of acupoints were described. The laws of the above mentioned combinations, the theoretic evidences and modern researches were summarized briefly. The mutual promotion and mutual assistance refer to the coordination of acupoints, presenting the relationship of the primary and the secondary about the mutual assistance. Hereby, the acupoints could be divided into the simple assistant acupoints and the acupoints from the affected meridians. The mutual inhibition is used to describe the antagonism effect in acupoint combination. There are more researches on the mutual promotion of acupoint combination but less ones on the mutual inhibition and its mechanism is just hypothetic. It is very important to have the deep study on those compatibility relationships for the improvement of acupuncture efficacy and to elaborate the effect mechanism.

Gastric cancer is a kind of disease with high incidence and mortality rate,most gastric cancer cases are diagnosed in an advanced,and chemotherapy is the main treatment.Drug resistance is one of the most important causes of therapy failure in gastric cancer patients.It has revealed that the mechanism of tumor resistance mainly involves alterations in cell cycle and proliferation,enhanced DNA repair capacity,defective apoptosis,damaged host immune,altered metabolism of drugs and so on.In recent years,an important molecule-microRNA(miRNA)that regulates the biological behavior of cell has attracted more and more attention.Studies have confirmed that numerous miRNAs can regulate the drug resistance of gastric cancer cells via BCL-2 signaling pathway,PTEN/PI3K/AKT pathway,ABCB1(MDR1/P-gp),autophagy,cell cycle and so on.

Objective To observe the clinical efficacy of application at Shenque (CV8) in treating primary dysmenorrhea due to blood stagnation.Method Sixty patients with primary dysmenorrhea due to blood stagnation were enrolled and randomized into a treatment group and a control group to receive the corresponding intervention, started 3 d prior to menstruation. The treatment group was intervened by application at Shenque with Chinese herbal medicinewhile the control group was by orally taking Ibuprofen sustained release capsules, successively for 3 menstrual cycles. The pre-treatment, short-term and follow-up dysmenorrhea scores and traditional Chinese medicine symptom and sign scores for blood stagnation were recorded, and the clinical efficacies of the two groups were observed.Result The short-term total effective rate was 93.3% in the treatment group, slightly lower than 96.7% in the control group, while the long-term therapeutic efficacy in the treatment group (93.3%) was obviously higher than that in the control group (50.0%). The changes in the symptom and sign scores for blood stagnation in the treatment group were more significantthan those in the control group, especially in the scores of menstruation amount, blocked menstrual flow, color of menstrual blood and blood clots (P<0.01). No adverse events occurred during the whole study. Conclusion Application at Shenque can effectively release menstrual pain and improve the symptoms of dysmenorrhea due to blood stagnation.

Objective To explore the influences on biological function induced by hyperthermia in human lung cancer cell line H1299, and to investigate the possible molecular mechanism. Methods H1299 cells were cultured in vitro and divided into 2 groups. The cells in culture flasks of hyperthermia group were immersed into a water bath at 43 ℃for 1 h, and the cells of control group were cultured at 37 ℃. The cell growth was detected by CCK8 assay, and the cell cycle and apoptosis rates were detected by flow cytometry [propidium iodide (PI) staining and PI/Annexin V staining]. The effects of hyperthermia on migration and invasion abilities of H1299 cells were determined by Transwell migration and invasion assays, respectively. The expression of LLGL1 was measured by Western blot. Results The cell cycle had no significant difference between the two groups, but the apoptosis rate was significantly higher in hyperthermia group [(24.81 ±2.80) %] than that in control group [(11.73 ±1.55) %] (t= 7.709, P= 0.0021). The migrating cell number was decreased in hyperthermia group (25.67±4.81) than that in control group (85.00±10.31) (t=5.182, P=0.0066). The invasive cell number was also decreased in hyperthermia group (22.00±2.08) than that in control group (108.3.0±10.14) (t=8.342, P=0.0011). The expression level of LLGL1 protein in hyperthermia group was 4.2 times that in control group(t=3.028, P=0.0389). Conclusion Hyperthermia induces the cell apoptosis and inhibits migration and invasion abilities of H1299 cells, which maybe associate with increasing LLG1 expression.

Objective The various influencing factors in the process of nano-silver preparation were studied in order to prepare nano-silver that has uniformity particle size distribution and good crystallinity. Methods Through the method of liquid reduction at room temperature,the nano-silver powders were prepared directly using silver nitrate as raw material,water as the reactive medium,polyvinylpyrrolidone(PVP) as protecting agent and ammonium formate as reducing agent. By means of EDS and TEM(transmission electron microscopy),the prepared silver particles were characterized. The various influencing factors in the process of preparation were also discussed. Results With the increasing concentration of AgNO3,the particle diameter of nano-silver changed obviously. When the concentration of silver nitrate was 0.25-0.30 mol/L,the size of product is the smallest. With the increasing concentration of reductant,the diameter of nano-silver decreased gradually. While at the concentration of 0.70 mol/L HCOOH,the average diameter of nano-silver is not more than 10 nm. Smaller and more well-distributed silver powder could be prepared at ratio of concentration of PVP to AgNO3 with the value of 1.5-1.0,at which PVP presented effective protection. Conclusions This method can prepare particle of nano-silver which revealed well dispersed and uniform size. The process is stable and reliable,easy to operate,high yields and suitable for industrial production.
