Objective To analyze the handling measure in period of ambo-operation and postoperative care of patients with abdominal surgery in advanced age over 80 years. Methods A retrospective analysis of 102 integrity data of patients with abdominal surgery in advanced age over 80 years was done. Results 100 patients recovery and discharged. The incidence of postoperative complications was 55.9% (55/102). Postoperative death was oberserved in two patients. Conclusion In patients over 80 years old,handling measure in period of ambo-operation is very impor-tant. Degeneration of organ function and more comorbidities made operation more dangerous. A well preoperative prep-aration and postoperative care, an intensive treatment of comorbiditius, the prevention of apoplexia and reducing the chance of emergency operation, will make operation more effective.

AIM:To investigate the effects of amnion epithelial cell ( AEC) suspension liquid on the biological behavior of the rabbit's corneal epithelium, combined with the in vitro and in vivo experiments. · METHODS: The rabbit's corneal epithelium were cultured in the lower chamber of transwell, and AEC suspension liquid was dropwised in the upper chamber. There was only culture medium in the upper chamber of the control group. The proliferation of rabbit's corneal epithelium was observed with CCK-8 automated colorimetry and the expression of PCNA was detected by immunocytochemistry. We used the scratch wound assay to detect the migration of corneal epithelial cell ( CEC ) . The in vivo models were established by placing a 10mm diameter corneal trephine in the center of the cornea, within 1mol/L NaOH for 1min. We divided those into three groups: treatment group of AEC suspension liquid eye drop, AEC suspension liquid subconjunctival injection and the control group without any treatment. Using the slit- lamp biomicroscope and fluorescence staining to observe the cornea per week. After 28d we took the eyeballs with the HE staining. The expression of VEGF was detected by immunohistochemistry. ·RESULTS: The activity of CEC with AEC treatment was much higher than the control group ( P< 0. 05 ). The expression of PCNA increased in AEC group (P<0. 05). And the migration of CEC in the AEC group was faster than the control one. In vivo, the inflammation of the corneal and the CNV of the AEC group were all significantly reduced compared with the control group (P<0. 05 ). There were less invasive cells and more ordered organization arrangement in ACE group observed by the HE staining. The expression of VEGF and mcp-1 in these two AEC treatment groups all significantly decreased compared with the control group (P<0. 05). ·CONCLUSION: AEC suspension liquid can promote the proliferation and migration of the rabbit's corneal epithelium. The potential of AEC suspension liquid as a therapy for acute corneal alkali burn.

This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

Objective To investigate the routine methods of α-amylase (AMY) test in scrum which meets the requirements of ISO 15189.Methods Fifty human serum samples with different concentrations of AMY (40- 750 U/L) were collected from March to December in 2008,to form the patients' frozen serum group.Four AMY measurement systems including Roche,Wako,MINDRAY and MAKER were used.The frozen standard materials with concentrations of ( 70.1 ± 3.7 ) U/L and ( 418.3 ± 22.1 ) U/L and the patients' frozen serum group were measured simultaneously by using IFCC reference method and 4 AMY measurement systcms based on 7170A automatic biochemistry analyzer.Thc linear regression analysis was made between the measurement results of each system and IFCC reference method.The equivalence,agreement and trueness were also evaluated by using the file EP9-A2 method.Bland-Altman GraphicalAnalysis and the improved Bland-Altman Graphical-Analysis of MVS1.80 software.Results Judging by the standards of IFCC reference method,the measurement results of 4 measurement systems were obviously different. ( 1 ) When measuring standard materials the results were 66.4,70.6,69.4 and 49.2 U/L respectively and 394.0,456.4,406.7,302.4 U/L respectively.The measurement results of MINDRAY were in agreement with that of IFCC reference method.( 2 ) When mcasuring the patients' scrum group by 4 measurement systems and IFCC reference method,the slopes of the linear regression equations were 0.934,1.070,0.930 and 0.731.respectively.And the intercepts were 0.886,6.249,5.388 and 3.574,respectively.According to the EP9-A2 method,the measurement results of Roche Wako,MINDRAY were equivalent to that of IFCC reference method.According to Bland-Altman Graphical-Analysis, the measurement results of Roche and MINDRAY were in agreement with that of IFCC reference method.The average biases of each measurement system were - 6.11％ ( Average bias ± 2s were 2.81％ and -9.40％ ),1.99％ ( Average bias ± 2s were 10.35％ and - 6.36％ ),- 2.70％ (Average bias ± 2s were 2.37％ and -7.77％ ) and -34.72％ ( Average hias ±2s were -24.20％ and -45.24％ ),respectively.According to the improved Bland-Altman Graphical-Analysis, the measurement results of MINDRAY are correct.The average biases of each measurement system were - 5.92％ (Average bias ± 2s were -2.81％ and -9.03％),2.10％ (Average bias ±2s were 10.74％ and -6.53％),-2.64％ ( Average bias ± 2s were2.24％ and -7.51％ ) and - 29.51％ ( Average bias ± 2s were 21.82％ and - 37.21％ ),respectively.Conclusions ( 1 ) The measurement results of different measurement systems do not necessarily have crreet results though they have claimed to have traceability.(2) The trueness of measurement results using the same system may not come to the same conclusion when evaluated by different methods.So laboratories should select and establish a procedure to evaluate trueness of routine methods and adopt those meeting the trueness requirements of ISO 15189.

Objective To evaluate the effect of health education path on advanced schistosomiasis patients with splenomega-ly in perioperative period. Methods A total of 60 advanced schistosomiasis patients with splenomegaly in perioperative period were randomly divided into an observation group and a control group (30 cases each group). The patients in the observation group were intervened by the nursing and health education from admission to discharge according to the standardized process of health education path,while those in the control group were implemented with the conventional health education. Then the satis-faction of nursing work,hospital stays,hospitalization expenses and mastery of health knowledge of the patients in the two groups were investigated and the results were compared. Results The satisfaction rates of nursing work of patients in the obser-vation group and the control group were 90%and 60%,respectively,the difference between them was statistically significant (χ2=7.57,P<0.05). The average hospitals stays of the above two groups were 14.0 ± 3.5 d and 19.0 ± 6.8 d(t=2.85,P<0.01),respectively,and the average hospitalization expenses were(1.5 ± 0.5)thousand Yuan and(2.2 ± 0.7)thousand Yuan (t=24.57,P<0.01),respectively,both of the differences were statistically significant. On the 10th day after surgery,the mas-tery rates of the health knowledge of the two groups were 96.7%and 50.0%,respectively,the difference was statistically signifi-cant(χ2=16.86,P<0.001). Conclusions The implementation of the health education path can promote the rehabilitation of advanced schistosomiasis patients with splenomegaly,and increase the satisfaction as well as improve the mastery of the health knowledge of the patients. Meanwhile,it also can cut down the hospital stays and save the hospitalization expenses.

Objective To discuss the allocation of oral medical resource in west area of Chongqing,and investigate the caries prevalence in these population.Methods Study samples was raised with the multistage stratified random cluster sampling method,then data was analyzed to compare the allocation of oral medical.Resource,awareness degree on oral health and caries prevalence in each age grade between urban and rural area.Results In west area of Chongqing,the allocation of oral medical resource and awareness degree on oral health were better in urban area than those in rural area.In each age grade,the caries prevalence is higher in rural area,when compared with that in urban area.In addition,the caries prevalence of 5 years old group and 12 years old group is the same between male and female in both urban area and rural area (P＞0.05).Nevertheless,in 35-44 years old and 65-74 years old group,the caries prevalence was higher in female compared with male in both urban area and rural area (P＜0.05).Conclusion In west area of chongqing,the rural allocation of oral medical resource is bad and needs improvement,the awareness of oral hygiene is weak among population of rural area.In west area of Chongqing,women in 35-44 years and 65-74 years old should pay more attention to caries prevention and treatment.

OBJECTIVETo investigate the incidence of the second mesiobuccal canal (MB2) in the mesiobuccal root of the maxillary first and second molars in Chinese population using three techniques, including the clearing technique, spiral CT scanning and serial root sections.

METHODSA total of 216 extracted human first and 334 second maxillary molars were randomly divided into two groups respectively: group A and B. The teeth in group A were cleared. The specimens in group B were subjected to spiral CT scanning, and then the roots were cross-sectioned every 1 mm from the root apex. Under the Dental operating microscope (DOM), the incidence of MB2 were recorded.

RESULTS(1) The incidence of MB2 in the first and the second maxillary molars were 81.48% and 49.70% respectively by clearing, and 77.78% and 47.31% from S-CT scanning, 88.89% and 53.89% respectively from serial root section. The occurrence of MB2 in maxillary first molars was statistically higher than in maxillary second molars (P < 0.05, chi square test). (2) There was no significant difference among the three approaches for detecting the MB2 canal (P > 0.05, chi square test).

CONCLUSIONSBoth the maxillary first molars and the second molars have high incidence of MB2.
