The clinical effect of Traditional Chinese Medicine (TCM) in the treatment of primary bronchial lung cancer is good. To a certain extent, TCM can control the progress of the disease and improve quality of life by the treatment of syndrome differentiation, disease-modified prescription, experience prescription, Chinese patent medicine, TCM injection, acupuncture and acupoint application, which have been combined with chemotherapy. The mechanism of TCM in the treatment of primary bronchial lung cancer mainly includes inhibition of lung cancer cell proliferation, induction of lung cancer cell apoptosis, improvement of body immunity and overcoming chemotherapy resistance.

Objective To research the mechanism or pathway through which Substance P(SP) inhibits r-aminobutyric acid(GABA) activated currents in bullfrog dorsal root ganglion(DRG) neurons.Method The experiment was conducted on freshly isolated bullfrog dorsal root ganglion neurons using a whole-cell patch-clamp technique.Results SP could caused a slow inward current when SP was applied to DRG neurons;SP could inhibits GABA-activated currents;The inhibition could be reduced largely when protein kinase C(PKC) inhibiter,1-(5-isoquinolinesulphorry)-2-methylpiperazine(H-7), was dialyzed in cell body.Conclusion The SP ton inhibit GABA-activated currents through protein kinase C.

Objective:To investigate the prognostic value of estrogen receptor (ER), progesterone receptor (PR), and Ki-67 in breast can-cer patients receiving neoadjuvant chemotherapy (NAC) and explore the association of chemotherapy regimens and cycles with the outcome of NAC. Methods:Clinical data of cancer patients receiving NAC were retrospectively analyzed. All the patients were admit-ted in Tianjin Medical University Cancer Institute and Hospital from January 2015 to December 2015. All statistical analyses were per-formed using SPSS version 19.0. The relationship among the outcome of NAC, molecular subtype, expression levels of ER, PR, and Ki-67, and chemotherapy regimens and cycles was investigated. Results:Only five HER-2(+) patients accepted the addition of trastuzum-ab in treatment, and few cases were excluded from the statistical analysis based on the effect of chemotherapy regimens. The effec-tiveness of NAC was positively correlated with the expression of Ki-67 whereas negatively correlated with the expression levels of ER and PR (P<0.05). In patients receiving NAC, the patients with Luminal subtype had worse outcome than those with non-Luminal sub-type (P=0.033). The invalid efficacy of pathologic evaluations of Luminal and non-Luminal NAC were 10.1%and 1.3%, respectively. No significant difference was found in the outcome among patients receiving TE, TEC, or EC-T;however, patients who received more than four cycles of NAC had better outcome than others (P=0.016). The outcome was statistically significant when the cut-off value of Ki-67 was 25%. Conclusion:Ki-67 proliferative index could be used as a prognostic marker to NAC in breast cancer patients. The cut-off value of Ki-67 should be determined on the basis of the data of each cancer patient. The curative effect of NAC was poor, and Luminal pa-tients with chemotherapy were insensitive and could be considered for surgical treatment. Patients who received less than four cycles of NAC had worse outcome than others, and prompt NAC foot treatment could improve the efficiency.

In this study, the effects of hyperosmolality on the expression of urea transporter A2 (UTA2) and aquaporin 2 (AQP2) were investigated in transfected immortalized mouse medullary collecting duct (mIMCD3) cell line. AQP2-GFP-pCMV6 and UTA2-GFP-pCMV6 plasmids were stably transfected into mIMCD3 cells respectively. Transfected mIMCD3 and control cells were cultured in different hypertonic media, which were made by NaCl alone, urea alone, or an equiosmolar mixture of NaCl and urea. The mRNA and protein expression of AQP2 was elevated by the stimulation of NaCl alone, urea alone and NaCl plus urea in AQP2-mIMCD3 cells; whereas NaCl alone and NaCl plus urea rather than urea alone increased the mRNA and protein expression of UTA2 in UTA2-mIMCD3 cells, and all the expression presented an osmolality-dependent manner. Moreover, the mRNA and protein expression of UTA2 rather than AQP2 was found to be synergistically up-regulated by a combination of NaCl and urea in mIMCD3 cells. It is concluded that NaCl and urea synergistically induce the expression of UTA2 rather than AQP2 in mIMCD3 cells, and hyperosmolality probably mediates the expression of AQP2 and UTA2 through different mechanisms.

OBJECTIVETo discuss the effect of matrine on nitric oxide (NO) and asymmetric methylarginine (ADMA) metabolism pathways in serum and tissues of mice with lipopolysaccharide (LPS) -induced intestine tissue inflammation.
METHODKunming mice were randomly divided into five groups: the normal control group, the LPS group and matrine (80, 40, 20 mg x kg(-1) x d(-1)) groups. The mice were intragastrically administered with drugs for 3 d (distilled water of the same volume for the normal control group and the LPS group). One hour after the last intragastrical administration, normal saline or LPS (1 mg x kg(-1)) were intraperitoneally injected. Twelve hours later, serum and tissues were collected to determine NO and ADMA levels and observe the pathological changes of intestinal tissues. The Western blot method was adopted to detect the protein expressions of arginine methyltransferases 1 (PRMT1) and dimethylarginine dimethylaminohydrolase 2 (DDAH2) in intestinal tissues.
RESULTCompared with the model group, matrine (80, 40, 20 mg x kg(-1) x d(-1)) groups showed lower NO content in serum and tissues, higher ADMA level in serum and increased PRMT1 expression in intestinal tissues, but without effect on DDAH2 expression.
CONCLUSIONMatrine could inhibit LPS-induced intestine tissue inflammation in mice. Its action mechanism is related to the decreased NO content in serum and tissues and increased ADMA level in serum and PRMT1 expression in intestinal tissues.
