ObjectiveTo solve the problem about the shortage of the human specimen,we aimed to reform the anthropotomy experiment teaching mode.MethodsThe nursing specialty students in Grade 2010 were randomly selected with 70 students traditional groups and 71 students teaching reform groups.The students of traditional groups were taught the key contents mainly in class time and were taught on the normally-exposed bottle specimen,while the students of teaching reform groups spend the primary class time on self-study.First,the students of teaching reform groups were informed of key contents and sealed bottle specimen. Second, the students of teaching reform groups observed only sealed bottle specimen in accordance with the main points of teaching materials.ResultsTeaching reform groups' average score of specimen examination is ( 81.30 ± 13.71 ),and theory examination is ( 70.83 ± 11.49 ),while the tradition groups' average score of specimen examination is ( 71.47 ± 16.00 ),and theory examination.is ( 66.29 ± 12.15 ).Results of teaching reform groups are much better than results of tradition groups in specimen test and theory test.Learning interest of teaching reform groups are elevated remarkably.They have improved much in their learning ability,cooperation ability,sense of group honor and the ability of originative thinking.ConclusionTeaching reform students' test result and comprehensive efficiency are promoted.The discussion-based experiment teaching mode is worth spreading.

Chinese medicine health care industry is in a well developmenting atmosphere, though there are still some problems restricting the development, such as small scale of business assert and sales, lack of new products. These happened mainly due to people’s attitudes, such as thinking highly of treatment than prevention, few policies supporting and not perfect regulations. It is recommended to strengthen innovation at the premise of a combination of government and market leading, and establish appropriate safeguards.

TCM health-care service industry is in a rapid growth phase. It is important to stimulate consumption and boost domestic demand in health-care industry. Although TCM has unique advantages in health-care industry, lack of technical standards, industry standards and related policy have led to market chaos. Limited by inherent concept of TCM health-care services and the existing enterprise scale and level, health-care services cannot get sufficient play. This article analyzed current situation and main problems of TCM health-care service industry, and provided measures and suggestions for management system, industry access, and personnel quality.

Objective To share the experience of heart thransplantation. Methods 3 recipients with terminal myocardiosis were reviewed. The transplantation was performed with inferior and superior vena anastomofic technique. During perioperative period, we selected and maintained the recipients, protected donor-isolated heart, supported circulation,decreased immune reaction and controlled infections. Results All the 3 patients survived. Heart function improved from NYHA class 1V before heart transplant to NYHA class Ⅰ, Ⅱ. The follow-up time was 19 months ,28 months and 49 months respectively. Rejection occurred in two cases due to non-compliance to medication. Conclusions Suitable recipient, proper donor heart procurement and preservation, suitable maintenance of circulation, proper managements of anti-immunitive reaction, prevention of infections are critical for successfal heart transplantation. Medicine-take required may avoid or reduce rejection.

Objective To find a way to measure and count plane distribution of cells distributed on single layer and compare differences of undifferentiated mesenchymal cells of periosteum germinal layer from different parts of the body.Methods After counting the number of undifferentiated mesenchymal cells of periosteum germinal layer from different parts of the body microscopically and figuring out the number of cells per area unit in each periosteum specimen,the obtained data were statistically analyzed and the stratum structure of periosteum observed microscopically.Results The homogeneity of variance test showed homoscedasticity,with no statistical significance(P＞0.05).The analysis of variance found homoscedasticity but showed no statistical significance(F=0.253,P＞0.05).The periosteum of patel- la,tibial plateau and costa had two layers,while the periosteum of costal cartilage had three layers. Conclusions There is no conspicuous difference upon proliferation and evoluting activities of periosteum from different parts of body.Therefore,it is unnecessary to choose specific parts for drawing the periote- um in clinical situation.In the meantime,the structure of periosteum from different parts diversifies.

OBJECTIVEThe role of air pollution on asthma can not be ignored, diesel exhaust particles (DEP) in the air is one of the most important pollutants. This study aimed to investigate the effect and mechanism of DEP inhaled on immediate reaction in the asthma rats.

METHODSixty male Wistar rats of "Clean" grade, 6 - 7 week-old, with an average weight of (140 +/- 20) g were used in this study. The rats were randomly divided into 6 groups, 10 in each. Group A was treated with normal saline attack as a negative control, Group B with ovalbumin attack as a positive control. After ovalbumin attack, groups C, D, E, F continued to inhale DEP for 1 week, 2 weeks, 3 weeks and 4 weeks, respectively. The concentration of DEP was 200 microg/ml, the animals were subjected to inhalation of ultrasound nebulized DEP for 30 min per day. One week after all the attacks were concluded, Group A was stimulated with normal saline for 30 min, other groups were stimulated with ovalbumin. Then the airway resistance was determined with multi-channel signal acquisition and processing system and compared. The changes in neutrophils, eosinophils, and other inflammatory cells of BALF and the pathological changes in lung tissue, including epithelial cells loss, the inflammatory cells infiltration around the airway, basement membrane fibrosis, goblet cell hyperplasia etc. were observed. The concentration of IL-5 and gamma-interferon in the lung tissues, and the changes of serum IgE etc. were determined.

RESULTAirway resistance values of group A, B, C, D, E, F after ovalbumin excitation for 30 min were (3.56 +/- 0.21), (7.06 +/- 0.63), (6.46 +/- 0.38), (7.47 +/- 0.33), (8.87 +/- 0.61), (11.00 +/- 0.69) cm H2O/(ml.s). No airway hyperresponsiveness occurred in group A, while Groups B, C, D, E, F had higher airway resistance than group A, group E and F had higher airway resistance than that of group B, the differences were statistically significant. And the airway resistance was different in each group among 0 min, 10 min, 20 min and 30 min (F = 160.646, 148.901, 162.204, 156.186, P < 0.01 for both). The time of DEP inhalation and the airway resistance was positively correlated (r = 0.948, P < 0.01); IgE concentrations of the serum between groups B, C, D, E, F was not significantly different (P > 0.05), but higher than that of group A (F = 2.639, P < 0.01). The infiltrated inflammatory cells included eosinophils and lymphocytes, etc. The percentages of neutrophil(%) were (4.3 +/- 2.0), (9.7 +/- 5.2), (10.3 +/- 5.6), (13.0 +/- 5.2), (42.6 +/- 18.3), (55.3 +/- 6.9). The groups E and F had higher percentage than Group A and Group B (F = 114.226, P < 0.01). The percentages of eosinophils(%) were 0, (11.9 +/- 3.8), (15.8 +/- 6.3), (13.0 +/- 4.9), (21.1 +/- 5.6), (27.1 +/- 4.8). The difference between Groups B, C, D, E, F and Group A was statistically significant. There was significant difference between groups C, D, E, F and group B (F = 46.462, P < 0.05); Lung tissue biopsy in group A showed that the epithelial cells were intact, no inflammatory cells infiltrations were found around the airways, instead, mainly ciliated columnar epithelial cells and only a small number of goblet cells were seen without basement membrane fibrosis. With the inhalation of DEP, the epithelial cells showed gradual necrosis, disruption and loss, goblet cells showed hyperplasia, and infiltrations with inflammatory cells were seen around the airway. In the lung tissue, concentrations of IL-5 in group B, C, and E were (12.8 +/- 2.8), (17.1 +/- 5.2), (18.6 +/- 4.2) pg/mg, the difference between groups C, E and group B was statistically significant (F = 4.236, P < 0.01), the difference in gamma-interferon concentration among all groups was not statistically significance (F = 1.185, P > 0.05).

CONCLUSIONDEP inhalation increased the airway responsiveness of asthma rats in immediate reaction, promoted the lung epithelial cell loss, inflammatory cell infiltration, basement membrane fibrosis and goblet cell hyperplasia.

OBJECTIVETo study the effects of immunoglobulin on the neuronal expression of IL-1beta and IL-1ra and the neuronal death at hippocampus in rats with convulsion induced by pentylenetetrazol.

METHODSThe epilepsy model was established by injecting intraperitoneally pentylenetetrazol (PTZ) into Wistar rats. Forty-five rats were randomly divided into three groups, normal control group, PTZ plus intravenous immunoglobulin (PTZ-IVIG); PTZ plus normal saline (PTZ-NS). Neuronal death was assessed by light microscopy with the hematoxylin-eosin (HE) staining and with in situ terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL). IL-1beta and IL-1ra expressions were examined by histochemistry.

RESULTSThe ratio of IL-1beta/IL-1ra at hippocampal CA(1) region in PTZ-IVIG group (0.5 +/- 0.1) was significantly lower than that in PTZ-NS group (1.9 +/- 0.5, t = 12.9, P < 0.05). Apoptotic cell numbers at the hippocampal CA(1) region were significantly decreased in the PTZ-IVIG group, compared to PTZ-NS group (t = 27.1, P < 0.05). The numbers of positive cells were 16.4 +/- 3.3/1000 microm(2) in the former and 41.7 +/- 3.5/1000 microm(2) in the latter. Necrotic cell numbers at the hippocampal CA(1) region were significantly decreased in the PTZ-IVIG group (19.0 +/- 2.6/1000 microm(2)), compared to PTZ-NS group (42.3 +/- 4.9/1000 microm(2), t = 20.9, P < 0.05).

CONCLUSIONImmunoglobulin could inhibit neuronal death induced by convulsion and its possible mechanism might be the regulation of IL-1 system in neurons.

Objective:To explore the mechanism of herb-partitioned moxibustion in relieving rat intestinal inflammation by focusing on the neutrophil extracellular traps(NETs)in Crohn disease(CD)development. Methods:Rats were randomly divided into a normal group,a model group,a herb-partitioned moxibustion group,and a mesalazine group.The CD rat model was prepared with 2,4,6-trinitrobenzene sulfonic acid except for rats in the normal group.Rats in the normal group and model group did not receive any treatment but had the same fixation as the other groups.Rats in the herb-partitioned moxibustion group received herb-partitioned moxibustion at Qihai(CV6)and bilateral Tianshu(ST25).Rats in the mesalazine group received intragastric administration of mesalazine enteric-coated tablets.The general situation of rats in each group was recorded,and the histopathological changes in the colon were observed and scored by hematoxylin-eosin staining.The serum concentrations of NETs DNA(NETs-DNA),neutrophil elastase(NE)-DNA,and myeloperoxidase(MPO)-DNA were detected by ABC enzyme-linked immunosorbent assay,and the citrullinated histone 3(citH3),MPO,and NE protein and mRNA expression levels in rat colon tissue were observed by immunofluorescence and real-time quantitative polymerase chain reaction. Results:Compared with the normal group,the mucosal ulcer reached the muscularis,the epithelium was incomplete,the goblet cells decreased obviously with significant inflammatory cell infiltration in the colon;the colonic mucosa damage index(CMDI)score increased significantly(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations increased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue increased significantly in the model group(P<0.01 or P<0.05).Compared with the model group,the mucosal epithelium in the herb-partitioned moxibustion group and the mesalazine group was repaired and the goblet cells increased with a few infiltrating inflammatory cells in the colon;the CMDI score decreased(P<0.01);the serum NETs-DNA,NE-DNA,and MPO-DNA concentrations decreased(P<0.05);the NE,citH3,and MPO protein and mRNA expression in the colonic tissue was down-regulated(P<0.01 or P<0.05). Conclusion:Herb-partitioned moxibustion reduced the serum NETs complex and inhibited the protein and mRNA expression of NETs complex in the colon tissue,which may be one mechanism of herb-partitioned moxibustion in relieving colon mucosal inflammation in CD.
