Objective To analyze the equipment and the working model of Pakistan international medical rescue team in Wenchuan earthquake in order to provide the first hand references for our medical rescue. Methods We analyzed the aim, the staff composition, the medical equipment, the logistic material and the working model of the Pakistan international medical rescue team by working with the Pakistan team, and summarized its strengths and weaknesses. Result The main aim of the Pakistan international medical rescue team is to search, rescue and treat the wounded and sick in mass casualty incident. The team consisted of 28 staffs, including 2 leaders (the executive leader was an epidemic expert, and the vise leader was an administrative officer), 6 clinical doctors, 2 nurses, 3 medical technicians, 10 field search and rescue staffs and 5 logistics staffs. The medical equipment included a field ambulance, 7 field tents and 2 marine satellite phones. The medical equipment and instruments include an X-ray table, a B-ultrasound scanner, an ECG tester, a set of surgery operation equipment and 2 sets of ICU instruments. The main medicines included antibiotics, analgesics and for trauma treatment. Narcotic drugs and surgical supplies supported 200 patients; fluid infusion and drugs were enough for 500 patients; other laboratory reagents were enough for 500 patients; oral drugs, disinfection cotton and bandages were for 3 000 patients. Logistics materials contained a set of cooking appliances, 2 sets of toilet facilities and enough rice, flour and water for the whole team for two weeks. The field tent hospital was built in one day. In the field tent hospital, 1 256 patients were treated, 14 surgeries were performed, 236 X-ray and B-ultrasound examinations as well as 314 biochemical examinations were conducted within 10 days. Conclusion With complete disciplines and rational structure, the configuration of the Pakistan team is fitful for its aim, and it balances the function of search, rescue and public health. Apart from equipment and instruments enough for 300-500 patients rescue, the team also considers both its own survival and environmental protection. The outcome would be better if they could arrive at the spot in the first week after the earthquake happened.
ObjectiveTo study the expression of cyclooxygenase2 (COX2) and its clinical significance in gastric carcinoma. MethodsThe expression of COX2 in 47 cases of gastric carcinoma and 16 cases of normal gastric tissue were detected by SP immunohistochemical technique. Helicobacter pylori (H.pylori) infection was diagnosed by urease experiment and Giemsa staining.ResultsThere was no positive signal of COX2 detected in normal gastric tissue. The positive expression rate of COX2 was 63.8%(30/47) in gastric carcinoma.The expression of COX2 was correlated with TNM stage, lymph node metastasis and H.pylori infection（P＜0.01）. Positive COX2 expression rate in H.pylori infection group was 72.4%(21/29), significantly higher than that in the group without H.pylori infection.Conclusion COX2 expression is involved in the carcinogenesis and malignant progression of gastric carcinoma.The examination of COX2 may be helpful to judge biological behavior of gastric carcinoma.
Objective To investigate the cl inical effect of Meek technique skin graft in treating exceptionally large area burns. Methods The cl inical data were retrospectively analysed from 10 cases of exceptionally large area burns treated with Meek technique skin graft from April 2009 to February 2010 (Meek group), and were compared with those from 10 casesof exceptionally large area burns treated with the particle skin with large sheet of skin allograft transplantation from January 2002 to December 2006 (particle skin group). In Meek group, there were 8 males and 2 females with an average age of 34.5 years (range, 5-55 years), including 6 cases of flame burns, 2 cases of hot l iquid burns, 1 case of electrical burn, and 1 case of hightemperature dust burn. The burn area was 82.6% ± 3.1% of total body surface area (TBSA). The most were deep II degree to III degree burns. The time from burn to hospital ization was (3.5 ± 1.3) hours. In particle skin group, there were 8 males and 2 females with an average age of 36.8 years (range, 18-62 years), including 5 cases of flame burns, 2 cases of hot l iquid burns, and 3 cases of gunpowder explosion injury. The burn area was 84.1% ± 7.4% of TBSA. The most were deep II degree to III degree burns. The time from burn to hospital ization was (4.9 ± 2.2) hours. There was no significant difference in general data between 2 groups (P gt; 0.05). Results The skin graft survival rate, the time of skin fusion, the systemic wound heal ing time, and the treatment cost of 1% of burn area were 91.23% ± 5.61%, (11.14 ± 2.12) days, (38.89 ± 10.36) days, and (5 113.28 ± 552.44) yuan in Meek group, respectively; and were 78.65% ± 12.29%, (18.37 ± 4.63）days, (48.73 ± 16.92) days, and (7 386.36 ± 867.64) yuan in particle skin group; showing significant differences between 2 groups (P lt; 0.05). Conclusion Meek technique skin graft has good effect in treating exceptionally large area burns with the advantages of high survival rate of skin graft, short time of skin fusion, and low treatment cost of 1% of burn area.
