Objective To study the current research status of minichromosome maintenance protein 2 (MCM2), the cell cycle proliferation marker, in the diagnosis of colorectal carcinoma. Methods Literatures about the application of MCM2 in the study of colorectal carcinoma were collected and reviewed.Results MCM2, as a marker of cell dysplasia and malignancy, was usually used in the study of carcinoma. The study on expression of MCM2 in the cell of colorectum in different proliferational stage might help to screen colorectal carcinoma as early as possible. Conclusion As a relatively specific and sensitive marker of cell proliferation, MCM2 might become a promising mark for diagnosing colorectal carcinoma in the early stage.

This paper discusses issues involved in the deployment of the shelters of campaign-grade rapid medical support system in such aspects as entering of the vehicles,unloading of the shelters and grouping of the staffs. It suggests that the vehicles should rapidly move in at their positions and be butted bidirectional. As the system is deployed,such things should all be fixed as the position of the vehicles & equipments as well as the deployment motions and sequence. The system is positioned at hard surface,the shelters should be pushed towards the immobilized vehicles,but for the system located at soft surface,it is quite the contrary. With the above-mentioned measures implemented,the duration for shelters of campaign-grade rapid medical support system can be reduced largely.

Objective To explore the impact of patients with esophageal cancer knowing diagnosis on the mental health of their children and investigate the factors.Methods 107 family carriers whose parent diagnosed esophageal cancer in General Hospital of Jinan Command were interviewed.Respondents were categorized into two groups:one group was those whose parents knew their diagnosis(Group A,n=45)and the other group was those whose parents did not know(Group B,n=62).The Chinese version of Self-reporting Inventory(SCL-90) was used.Results The scores of 107 children of esophageal cancer patients in depression(1.62±0.30),anxiety(1.78±0.34) and hostility (1.93±0.47) were higher than national norms (P＜0.01).Compared with group A,group B showed a significant higher degree of anxiety((1.89±0.33) vs (1.62±0.33),P＜0.01).In multiple regression analysis,age and the knowledge of esophageal cancer diagnosis had statistically significant difference (P＜ 0.05).Conclusion Patients' knowledge of the esophageal cancer diagnosis contribute to relieving family carers' symptoms of anxiety.

Objective　 To investigate the efficacy and security of the treatment for the with visual function in neovascular glaucoma with Ahmed glaucoma value(AGV ).Methods　Twenty-six cases (26 eyes) with visual function in neovascular glaucoma underwent AGV implantation. Results　After surgery，the follow-up periods lasted for 4 to 26 months (mean 8 months ),the visual acuity of 22 eyes (86.4%) was improved or remained the same，no case of the blindness was found. The mean intraocular pressure was between 0.8～2.8kPa in 17 eyes，and the Yate of control reaches to 65.4% , the postoperative complication included transicent hyphema, Early hypotony, obstruction of the tube tip and drop out of the plate.Conclusion　The AGV implantation treating those with visual function in neovascular glaucoma is an effective and safe method.

It is very necessary to apply case-teaching method to Emergency Medicine in Universities of TCM. To establish the case-teaching system,we ourselves have written teaching materials,trained teachers, and designed all sorts of the medical records. Moreover, we have deployed other methods and principles to put this teaching into practice, used clinical skill practising as a essential supplement of teaching effect. Comparing with the traditional teaching method, it is clear that case-teaching method could make students' learning initiative and positivity improved significantly, their test scores promoted obviously. Thus, carrying out case-teaching method in Emergency Medicine could advance students capability of acquisition of knowledge and their clinical thinking .

Objective: To study the effects of rapid eye movement sleep (REMS) deprivation on active behavior and the expression of mRNA coding for inducible nitric oxide synthase (iNOS) of hypothalamus in rats. Methods: The flower pot technique was adopted to deprive the REMS of Sprague Dawley rats for 24 h, 48 h and 72 h respectively. The active behavior of rats were examined by the open field test (OFT). The expression of mRNA coding for iNOS of hypothalamus in rats was assayed by reverse transcription polymerase chain reaction (RT PCR). Results: The OFT scores were significantly increased in rats subjected to 24 h and 48 h REMS deprivation ( P 0.05). There was no difference in the expression of iNOS mRNA among 24 h, 48 h REMS deprivation and the control groups, but the expression was significantly increased in 72 h REMS deprivation group ( P

The present study was to examine the effect of stellate ganglion block (SGB) on bilateral regional cerebral oxygen saturation (rSO2) and postoperative cognitive function. Eighty patients undergoing selective coronary artery bypass graft with cardiopulmonary bypass (CPB) were randomly and equally divided into two groups. The patients in group S were given right SGB with ropivacaine, while the patients in group C were injected with normal saline. We compared the bilateral rSO2 after SGB. Minimum Mental State Examination (MMSE), Visual Verbal Learning Test (VVLT), and Digital Span Test (DST) were applied to observe the effect on cognitive function. We found that the incidence of postoperative cognitive dysfunction (POCD) 7 days after surgery in group S was lower than that in group C. The level of blocked side rSO₂ of S group were significantly higher before CPB time of rewarming than that before SGB (P < 0.05), much higher than corresponding non-blocked side rSO₂ before CPB (P < 0.05), and much higher than rSO₂ level in group C before CPB and after CPB (P < 0.05). The non-blocked side rSO₂ in group S before anesthesia were much lower than basic levels and those in group C (P < 0.05). It could be concluded from the above results that there was significant increase in the blocked-side rSO₂ compared to the non-blocked side and there was significant decrease in the incidence of POCD compared to the control group after SGB.

BACKGROUND:The preliminary findings confirm that bone marrow mesenchymal stem celltransplantation is safe and effective in the treatment of acute myocardial infarction, but its exact mechanism is unclear. There are few studies addressing the survival status of transplanted stem cells and its acting timing.
OBJECTIVE:To study the survival of rat bone marrow mesenchymal stem cells transplanted into the infracted myocardium. METHODS:Bone marrow mesenchymal stem cells were cultured using density gradient centrifugation. Eighty rat models of myocardial infarction were prepared. Bone marrow mesenchymal stem cells were injected via a microsyringe at four sites around the infarcted region at 14 days after modeling. Then, 70 rats with living cells were selected for detecting the survival of bone marrow mesenchymal stem cells at days 3, 5, 7, 10, 20, 28 after transplantation. RESULTS AND CONCLUSION:Under ×400 visual field, the number of Brdu-positive bone marrow mesenchymal stem cells was (36±12) at 3 days posttranplantation, (33±13) at 5 days, (28±9) at 7 days, (15±5) at 10 days, (5±3) at 14 days, 0 at 20 days, and 0 at 28 days, showing a overal downward trend after transplantation. The number of bone marrow mesenchymal stem cells was negatively correlated with transplant days (P<0.01, r=-0.47). The number of cells decreased most significantly within 1 week after transplantation, and then decreased to 0 at 20 days. These findings indicate that transplanted bone marrow mesenchymal stem cells in the myocardium cannot survive for a long term and also cannot be transformed into myocardial tissue.
