Mental matching is a strategy of teaching materials transacting in emotional latitude of teaching psychology. Used properly, psychology matching strategy can improve the unification between teaching materials and students' need to adjust to the students' learning interests. This paper introduces the connotations and functions of mental matching strategy, and two types of mental matching strategies in the nursing ethics teaching are analyzed.

In order to improve the scientificity and rationality of materiel management,we developed the materiel management system and realized the computerizing of material management. This system can solve all problems in material computerizing which occur during the process from the material application to its abandonment. Aiming at solving disadvantages in human management,the utilization of this system will greatly reduce the staff's work load,enhance the working efficiency and make the material management standardized.

Objective To investigate the potential factors which have impact on the working space for surgeons in gasless laparoscopic cholecystectomy and to probe into the specifications of gasless surgeries.Methods Clinical data of 49 cases of gasless laparoscopic cholecystectomy between March 2007 and July 2010 were summarized.The impacts of body mass index,bowel preparation and means of anesthesia on operation time and conversion to laparotomy were analyzed.Results For patients with body mass index ≤25and ＞ 25,operation times were (43.0 ± 5.4) min,and (52.8 ± 7.4 ) min,respectively,and rates of conversion to laparotomy were 0/34 and 4/15,respectively.Both indices in the first group were higher.For patients with and without bowel preparation,operation times were (44.5 ± 5.4) min and (46.1 ± 8.0)min,respectively,and rates of conversion to laparotomy were 2/26 and 2/23,respectively.For patients with epidural anesthesia and lumbar/epidural anesthesia,operation times were (46.5 ± 7.9) min and (44.1 ±6.8) min,respectively,and rates of conversion to laparotomy were 2/24 and 2/25,respectively.Conclusions The operation time of gasless laparoscopic cholecystectomy could be affected by many factors,such as body mass index.Gasless operations can be improved by evaluating the conditions of patients correctly and by selecting suitable operation methods,anesthesia means and bowel preparation.

Objective To investigate the protective effects of leptin on neonatal seizure in rats by behavioral tests and Bcl2 expression.Methods Twenty Sprague-Dawley (SD) rats were divided into four groups:control group,leptin group,RS group and RS+leptin group on postnatal day 6 (P6),5 rats in each group.From P6 to P12,repeated neonatal seizure model was induced by flurothyl in RS and RS+leptin group rats.From P13 to P22,leptin (2 mg · kg-1 · day-1) was administered by intraperitoneal injection in leptin group and RS+leptin group rats.Forelimb hanging test and open field test were implemented on P30.Bcl2 expression was detected by western blot on P34.Results (1) Neurobehavioral tests:the time of forelimb suspension in RS group((7.10± 1.02) s)was significantly shorter (P＜0.05) than the control group((15.95± 6.11)s) and the time of forelimb suspension in RS+leptin group((13.90±2.64) s)was significant longer (P ＜0.05) than the RS group.In open field test,the number of horizontal movement in RS group (119.80± 28.83) was significantly reduced (P＜0.05) than that in the control group(191.00±37.27) and the number of horizontal movement in RS+leptin group(164.20±26.46) was increased than that in the RS group,but the difference was not significant.The number of modification and stool in RS group was significantly increased (P＜0.05) than that in the control group and the number of modification and stool in RS+leptin group was significantly reduced (P＜0.05) than that in the RS group.(2)Western blot:the expression of Bcl2 in RS group (0.24±0.07),leptin group(0.89±0.09) and RS+leptin group(0.56±0.07) was significantly decreased compared with control group(1.02±0.01) (P＜0.05),and the expression of Bcl2 in RS +leptin group was significantly increased compared with RS group (P＜0.05).Conclusion Leptin improves the brain injury induced by flurothyl on neonatal rats by Bcl2 signaling pathway.

Objective To study the expression of reversion-inducing-cysteine-rich protein with Kazal motifs (RECK) in human pancreatic carcinoma tissues and pancreatic carcinoma cell lines; the effects of recombinant lentiviruses carrying RECK gene(LV-RECK) therapy on human pancreatic carcinoma xenograft in nude mice; and to find out the relationship between the expression of RECK and the prognosis of pancreatic carcinoma.Methods Immunohistochemical method was used to detect the expression of RECK in the resected specimens of pancreatic carcinoma and their corresponding normal pancreatic tissues in 42 patients.Western blotting was used to examine the expression of RECK in human pancreatic carcinoma cell lines (PANC-1,MIAPaCa-2,AsPC-1).Statistical analyses were performed to determine the relationship between RECK expression and the clinicopathological characteristics and prognosis in pancreatic carcinoma.Subcutaneous xenograft tumor models of human pancreatic carcinoma were established in nude mice.These nude mice were then divided into the experimental group,the negative control group and the blank control group randomly.The three groups of nude mice were intratumorally injected with LV-RECK,LV-EGFP and normal saline (NS) respectively.The antitumor effect was studied.Immunohistochemical method was used to detect the expression of RECK and microvessel density (MVD).Terminal deoxynucleotidyl transferase mediated dUTP-DIG nick end labeling (TUNEL) was used to detect the apoptosis of tumor cells.Survival analysis was performed.Results All three pancreatic carcinoma cell lines did not express RECK.The overall positive rate of RECK expression was 45.2 ％ (19/42) in pancreatic carcinoma,and 88.1 ％ (37/42) in normal pancreatic tissue.The expression level of RECK was significantly lower in the tumor tissues than in the normal tissues (P＜0.01).The expression of RECK was significantly associated with TNM stage,lymph node metastasis and local infiltration of pancreatic carcinoma (P＜0.05).Kaplan-Meier survival analysis revealed that the survival time was significantly longer in the RECK positive patient group than in the RECK negative patient group.Univariate Cox regression analysis revealed that RECK expression,TNM stage,lymph node metastasis and local infiltration were significantly related with prognosis for pancreatic carcinoma (P＜0.05).Multivariate Cox regression analysis revealed that only RECK expression remained as an independent significant factor in predicting the prognosis of pancreatic carcinoma (P ＜ 0.001).When compared with the negative control and the blank control groups,the volume of subcutaneous xenograft tumor in the experimental group was significantly decreased (P＜0.05).RECK protein in the experimental group was re-expressed.MVD of the experimental group was significantly less than those of the control groups (P＜0.05).Apoptotic index (AI)of the experimental group was significantly higher than those of the control groups (P＜0.05).The survival time of nude mice in the experimental group was significantly longer than those in the control groups (P＜0.05).Conclusions RECK expression was closely related to invasion,metastasis and prognosis of pancreatic carcinoma and it was an independent prognostic marker.RECK gene over-expression inhibited neovascularization of pancreatic carcinoma,induced apoptosis of tumor cells,inhibited the growth of tumor xenograft and improved the prognosis of tumor-bearing mice.These results suggest a possible new treatment for pancreatic carcinoma.

A 59-year-old man was admitted to the Department of Ear, Nose and Throat with a complaint of six-month history of left facial numbness and toothache. There was no special previous medical history in addition to smoking. No obvious abnormality in routine electrocardiogram, chest X-ray, abdominal B ultrasound were found. (1) CT scans showed heterogeneous shadows in maxillary sinus with the lesions on the left max- illary bone and evidently destruction of alveolar bone. The histopathological examination revealed bone tissue which was partly covered by an intact adenocarcinoma cell. (2) Immunohistochemical staining foe CK7, CD117, thyroid transcription factor-1, and novel aspartic proteinase A were positive and thus compatible with metastatic lung adenocarcinoma. (3) Chest CT scans showed a 1 cm x 2 cm mass on the superior lobe of the left lung, with destruction of sternum and rib, confirming that the lesions in the paranasal sinuses were lung cancer metastases. Therefore, this patient conclusively diagnosed as lung adenocarcinoma with multiple bone metastases.
