Hemodynamic effects of Laigechongji (LGCJ)were studied in anesthetized open-chest dogs. LGCJ(in doseof 8. 5 and 17.0g/kg,id. )decreased significantly SBP, DBP, MAP, HR, LVSP, +dp/dt max and TPVR, 30~45 mins after medication,and continued for about 90~ 150mins. However,they had no significant effects ondp/dt max,LVEDP,CO,CI,SV and SI. These results suggest that LGCJ may cause hypotension,and its hypotensive effects may be related to its bradycardiac,negative inotropic and vascular resistance reducing activities.

Objective To investigate the relationship between positive peritoneal exfoliated cancer cells and the clinicopathological features of patients with hepatocellular carcinoma before any invasive treatment.Methods Of the 92 patients with hepatocellular carcinoma who underwent laparotomy,ascites fluid was collected in the patients with peritoneal ascites; and peritoneal lavage fluid was collected in those patients without peritoneal ascites.Then,shedded cancer cells in these fluid samples were detected.Results The positive rates of peritoneal cancer cells were associated with the TNM stage,tumor location and tumor size.The positive detection rate of cancer cells in TNM stage Ⅲ and Ⅳ was significantly higher than stage Ⅰ and Ⅱ (38.1％ vs 8.0％ ; P =0.0005).The positive detection rate was higher in tumors located closer to the surface (P =0.0 002),and with larger diameter (P =0.00 007).Conclusion Peritoneal cancer cells were significantly correlated with tumor stage,tumor location and size in hepatocellular carcinoma.

Objective To study the effects of community nursing interventions on stroke patients with attention disorders.Methods A total of 60 stroke patients fulfilling eligibility were divided randomly into two groups.Their data were collected between December 2010 and February 2012.The intervention group was treated by community nurses while the control group trained by family members.Attention was assessed by simple reaction time (SRT) and number cancellation test (NCT).Modified Barthel index was used to assess the activities of daily living (ADL).Both groups were evaluated before and after a 2-month intervention.Results Before treatment,the control group had(0.71 ± 0.25),(662.8 ± 152.7) and(31 ±8)scores at SRT,NCT and MBI respectively.And the intervention group yielded(0.69 ± 0.19),(652.7 ±131.0) and (30 ± 8)scores at SRT,NCT and MBI respectively.There were no significant differences in average value of SRT,NCT and MBI between training and control groups at pre-treatment (P ＞ 0.05).After 2 months,the control group had (0.68 ± 0.20),(637.4 ± 151.7) and (33 ± 8) scores at SRT,NCT and MBI respectively.And the intervention group yielded (0.56 ± 0.16),(540.3 ± 125.9) and(37 ± 8) scores at SRT,NCT and MBI respectively.Very significant difference existed in attention scale scores at Month 2 (P ＜ 0.01) and the difference in ADL scale scores was also significant (P ＜ 0.05).Conclusion For stroke patients with attention disorders,strengthening community nursing interventions may help to improve attention and boost activity of daily living.

Objective To investigate the risks of operative contamination of surgical gear by exfoliated cancer in 78 patients who received surgery for hepatocellular carcinoma.Methods Surgical gear from 78 patients who were operated for primary hepatocellular carcinoma were divided into four groups:A.surgical instruments; B.surgeon gloves; C.gauze and gloves used for cleaning equipment; D.gauze and gauze pad used for cleaning operation area.Saline was used to soak the surgical gear followed by low speed centrifugation.The precipitate was stained and then observed for cancer cells.Results The positive rates of cancer cell on surgical gear were significantly associated with the TNM stage,tumor location,tumor size,and surgical approach.The positive rate of liver cancer cell on surgical gear in TNM stage Ⅲ was higher than TNM stage Ⅰ / Ⅱ (56.3％ vs 21.7％,P=0.002).The positive rate of cancer cell on surgical gear was significantly related to tumor size and location (P=0.006,P=0.001).The positive cancer cell detection rate of non-anatomical liver resection was significantly higher than anatomical resection (53.8 ％ vs 26.9 ％,P =0.019).The positive cancer cell detection rate was significantly associated with different types of surgical gear (P=0.008),in which group C showed the highest cancer cell detection rate.Conclusion The risks of cancer cell contamination of surgical gear were significantly associated with progression of hepatocellular carcinoma,tumor size,location and surgical approach,and also associated with the frequency in the use of surgical gear,the operation scope of contact and the nature of surgical gear.

Objective To incubate the rat neural stem cells with specific inhibitor (PD98059) of MAPKK/MEK to clarify the effect of MAPKK/MEK-MAPK/ERK signaling pathway in neural stem cells (NSC).Methods NSCs derived fiom E15-16 rats were isolated and cultured.After treated with different concentration of PD98059,they were subjected to the detection of cell proliferation,Nesn'n, BrdU and β-tubulin-Ⅲ by WTS-8 assay,immunofluorescent staining or Western Blot respectively.Results PD98059 had an effect on the survival,proliferation and differentiation of NSC at a concentration-dependent manner.The viability of the NSC was significantly decreased than the control (P＜0.05),whereas the numbers of BrdU-positive and β-tubulin-Ⅲ positive cells were notably fewer than the control (P＜0.05) after incubated with the higher concentration of PD98059.The ERK expression was blocked by PD98059 at a concentration-dependent manner.Conclusion The MAPKK/MEK-MAPK/ERK signaling pathway played a vital role in the survival, proliferation and differentiation of NSC.

Objective This study investigated a method to rapidly inactivate tumor cells on surgical instruments intraoperatively.Methods Tumor cells were collected by immersing and washing the surgical instruments in 37 ℃ saline.The precipitation was collected by low speed centrifugation and then was cultured to harvest the tumor cells.The tumor cells were immersed in saline and distilled water of different temperatures for different duration of time.Inverted microscopy was used to investigate the changes in morphology.Results After immersion in 55 ℃ distilled water for 60 seconds,the tumor cells were swollen,the cell membranes disappeared,the sizes of the nuclei were reduced,the chromatin was condensed,and some cells lysed and separated from each other.Additionally,these tumor cells floated in the culture medium and lacked any living cells adhering to the walls of the bottle.In the group of tumor cells treated with 55 ℃ saline for 60 seconds,there were no obvious morphological changes of the tumor cell or nucleus.Conclusion The intraoperative immersion of surgical instruments in 55 ℃ distilled water for 60 seconds could completely inactivate tumor cells.
