Objective To evaluate the efficacy of the continuation of cardiopulmonary resuscitation (CPR) following transportation to the emergency department in a Chinese hospital after unsuccessful emergency medical services (EMS) CPR. Methods From January 2002 to December 2007, emergency records of non-traumatic patients who were transported to a tertiary teaching hospital after unsuccessful EMS CPR were reviewed. Results Eigty-five patients were included, and 13 patients (15%) accomplished restoration of spontaneous circulation in our emergency department. Resuscitative possibility reached zero at around 23 minutes. One patient was discharged with a favourable neurologic outcome. Conclusions This study shows that the continuation of CPR is not futile and may improve outcomes. The outcomes should be re-evaluatad in the future when prehospital information can be combined with in-hospital information.

Objective To observe the pathophysiological changes of heat exposed (41.0-41.5 ℃) rats, including the change of rectal temperature (core temperature, Tco), mean arterial pressure (MAP) , heart rate (HR) and the protein expression characteristic of Hsp70 mRNA in the brain, heart and lung. Methods After Tco was measured, Wistar rats were exposed to the heat environment (a chamber, 41.0-41.5 ℃) till to death. Tco, MAP and HR were monitored continuously by the temperature measurement instrument and remote sensing pressure-monitoring system. The expressions of Hsp70 mRNA and protein in the brain, heart and lung were determined by RT-PCR and Western blot. Results Tco, MAP and HR increased continuously when the rats were exposed to the heat environment. After MAP and HR started decreasing from peak value, heatstroke was induced. The time to induce heatstroke in the heat environment (41.0-41.5 ℃) was (35?2) min. After heatstroke MAP quickly decreased and HR was not normal. At last, Tco increased to the peak (45.0 ℃) and the animal was dead. The expressions of Hsp70 mRNA and protein in the brain and heart were low and the expression in the lung was high while they were obviously induced by heat treatment. The level of Hsp70 mRNA in the brain, heart and lung was approximately 5.19, 6.88 and 1.80 times of that in the normal control group (P

This study collected demographic data, past history, personal history, family history, dosage, solvent, combined medication information of adverse reaction cases from a prospective, multi center, large sample intensive hospital monitoring, and found the influencing factors with cross-tab analysis. The results showed that in the medication group of 19-45, patients with allergic histories had a higher proportion in ADR; in the medication group of 46-65, male patients with allergic histories had a higher proportion in ADR; indication and non-indication group, patients of 19-45 years old, with combined medications and allergy histories had a higher proportion in ADR; Non-indication medication group, patients with combined medication, higher concentration, out-instruction solvent and dosage, had a higher proportion in ADR. So, the ADRs of Shenfu injection were related to the history of drug allergy, and also related to the indication, dosage, solvent, concentration when it was used.

Objectiye To study the mechanism by which transcranial magnetic stimulation (rTMS) affects cognitive dysfunction in vascular dementia (VD). Methods Thirty-six male Wistar rats were randomly divided into a control group, a VD group, a low frequency rTMS group and a high frequency rTMS group. Two-vessel occlusion was employed to induce VD models. Low frequency rTMS group rats were given 0.5 Hz rTMS for six weeks. High frequency rTMS group rats were given 5 Hz rTMS for six weeks. Morris' water maze test was used to measure their spatial learning ability and memory. The ultrastructures of the synapses in the four groups were detected with transmission electron microscopy. The expression of synaptophysin (SYN), brain derived neurotrophic factor (BDNF) and Nmethyl-D-aspartate receptor 1 ( NMDAR1 ) mRNA and protein in the hippocampus were determined by real-time PCR and Western blotting. Results The behavior and morphology of the rats treated with rTMS improved. The average expression of SYN, BDNF and NMDAR1 mRNA and protein in the low frequency rTMS group and the high frequency rTMS group were significantly higher than in the VD group. Conclusion rTMS can provide a rehabilitative effect for VD. The mechanism might be associated with enhancing the expression of SYN, BDNF and NMDAR1 in the hippocampus.

The development of medical imaging diagnosis technology has brought forward higher requirements for the teaching of oral and maxillofacial medical imaging diagnostics, In this study, we intro-duce the methods and concepts of comparative imaging to guide students to analyze and compare oral and maxillofacial diseases from different perspectives, and to promote the students' understanding of the disease image and mastery of disease diagnosis, improve the students' ability to choose the appropriate imaging method in the future clinical work. Comparative imaging is one of the important teaching methods in the diagnosis of oral and maxillofacial medical imaging, and it is also the direction of its future development.

Objective To learn the psychological needs of the hospital staff in terms of their life,medical care and psychological health.Methods 2910 hospital staff were interviewed with questionnaires and the outcomes analyzed with x2 test and descriptive analysis.Results 96.9％of the surveyed found themselves in need of psychological counseling; considerable consulting needs of the staff; most of them turn to friends to complain instead of their leaders.Conclusion The psychological counseling should be enhanced to build effective communication channels and ease stress of the staff.

Background Mesenchymal stem cells (MSCs) have been applied in basic and clinical researches of organ transplantation.Our previous study showed that intravenous injection of MSCs prolonged corneal allograft survival in rat.However,the effect of local administration of MSCs on corneal allograft rejection remains unclear.Objective The aim of this study was to investigate the effect of subconjunctival injection of MSCs on corneal allograft rejection in rat model of keratoplasty.Methods MSCs were isolated and cultured from femur and tibia bone marrow of clean Wistar rats,and then the cells were identified by induced differentiation of osteoblast and adipocyte.The third generation of MSCs was used in subsequent experiment.Allogenic penetrating keratoplasty was performed with the bilateral corneas of 20 Wistar rats as donor grafts and the right eyes of 40 Lewis rats as recipients.PBS 0.1 ml containing 2 × 106 MSCs and 0.1 ml PBS only was subconjunctivally injected immediately and postoperative 3 days respectively in randomized two groups,and another 6 normal Lewis rats served as the normal control group.Corneal rejection response was evaluated under the slit lamp after surgery based corneal opacity,edema and neovascularization,and the grafts were scored according to the criteria of Larkin.The corneal samples were extracted from 12 rats of the PBS control group and the MSCs group separately 10 days after surgery.The relative expressions of Th1 cytokines (interferon-γ [IFN-γ] mRNA and interleukin-2 [IL-2] mRNA) and Th2 cytokines (IL-4 mRNA and IL-10 mRNA) were detected by real-time quantitative PCR.Protein levels of IL-4 and IL-10 proteins in the corneas were assayed by ELISA.All experimental protocols involving rats were approved by the laboratory animal care and use committee of the Tianjin Medical University and treated with the ARVO statement for the use of animals in ophthalmic and vision research.Results The cells grew well with the orange stain for alizarin red in differentiated the osteoblasts and red stain for Oil red O in differentiated adipocytes.The survival time of corneal graft in the MSCs group was (11.8±1.6) days,it was significantly longer than (9.6±1.4) days in the PBS control group (P=0.004).The levels of IL-4 mRNA and IL-10 mRNA in the MSCs group were significantly higher than those in the PBS control group (both at P =0.00);while the levels of IFN-γ mRNA and IL-2 mRNA were not significantly different between the groups (both at P＞0.05).The IL-10 protein contents were (22.74 ±7.06),(68.40±12.83) and (215.41 ±44.66)pg/ml in the normal control group,PBS control group and MSCs group,showing significant difference among the three groups (F =55.06,P =0.00) and a significant increase in the MSCs group compared with the PBS control group and the normal control group (both at P ＜ 0.05).Conclusions Subconjunctival injection of MSCs prolongs the survival time of cornea allograft in penetrating keratoplasty probably by modulating the balance between Th1 and Th2 cytokines,especially by up-regulating Th2 cytokines.
