Objective To analyze the causes of misdiagnesis and mistreatment of traumatic abdominal hernia. Methods In this study,11 cases of traumatic abdominal hernia admitted during 1971 to 2004 were retrospectively analyzed.Hernia located subcutaneously in 8 cases including incarcerated hernia in 2 csses.Hernia located intermuscularly in 2 cases with one case being incarcerated.and the other strangulated.One located retroperitoneally.Among the 11 cases,3 were simple hernia,8 were complicated with injuries of other organs. Results Eight cases were misdiagnosed,5 were operated on with wrong incision,and in one case the herniated intestinal loop,mistaken as hematoma,was incised.All these 5 cases underwent a second surgery due to failure in repairing the hernia. Condusion For traumatic abdominal wall hernia,correct diagnosis,the correct timing of operation and an appropriate incision chosen insure good therapeutic results.

The expression of proliferating cell nuclear antigen (PCNA) was studied in 50 cases of squamous cell carcinoma of the skin using immunohistochemistry and PCNA cyclin monoclonal antibody. PCNA staining was found in the nuclei of tumour cells, two types of staining were seen, a granular pattern and a more diffuse nuclear staining. The expression of PCNA showed a significant positive correlation with degrees of differentiation of the carcinoma cells and lymph node metastasis (P

The expressions of p53 protein, PCNA and macrophage count in 50 cases of skin squamous cell carcinoma were studied by LSAB immunostaining of monoclonal antibodies (PC-10, CD68 and Do-7). The relationship between the proliferation of cancer cell and the count of stroma macrophage to the degree of differentiation was studied and observed in situ. The results showed that the positive rates of expression of both p53 protein and PCNA in the squamous cell carcinoma were 56% and 100%, respectively. The distribution and strength of the expression of p53 protein and PCNA were positively correlated to the degree of cell differentiation. Macrophoge regularly located in the margin of cancer nest. The macrophage count was reversely correlated to the degree of differentiation. It is concluded that the degree of differentiation is parallel to the expression of p53 protein and PCNA, whereas, the macrophages in the stroma to some extent inhibits the cancer cell proliferation.

The skin organ model can be cultrured in ways of organ culture and organotypic raft culture It can be used in skin transplantation,pharmacy or investigate the mechanism of pigmentation. Though there are many ways in culturing skin organ model,how to further improve technology to produce more similar to human's skin organ,and put it in treating dermatosis still needs further exploring. The model of skin organ provides a good platform for new drug development,toxicology experiment and physiological function research. Some tissues engineering skin products have been approved by Food and Drug Administration in America for clinical use. It is believed that following the development of tissue engineering and relative subjects,skin organ culture model in vitro will become one of the effective means on dermatosis study.

Objective To investigate correlation study of serum hs-CRP,UA level and the correlation of dis-ease in elderly acute myocardial infarction patients , and provide a reference basis for clinical judgment for patients with illness development and prognosis prediction .Methods 40 aged patients with acute myocardial infarction pa-tients were selected as the research object ,and protionally random according to time admission the same period ran-domly selected were 40 cases of elderly patients with unstable angina pectoris ,40 cases of elderly patients with stable angina,40 cases of clinic medical normal healthy old people for controlled object .The levels of serum hs-CRP,UA and correlation was analyzed.Results The serum hsCRP,UA in the myocardial infarction group were (34.67 ±12.18)mg/L, (412.46 ±68.93)μmol/L,which in the unstable angina pectoris group were (17.21 ±8.39) mg/L,(274.19 ± 46.62)μmol/L,which in stable angina pectoris group were (5.25 ±1.40) mg/L,(297.41 ±37.43)μmol/L,which in the health group(4.96 ±1.24)mg/L,(279.64 ±34.78)μmol/L,the differences among the myocardial infarction group,unstable angina pectoris,stable angina pectoris group had statistical significance (P<0.05), the differences between myocardial infarction group and health group had statistical significance (P<0.05);Myocardial infarction patients prognosis group hs-CRP,UA group was obviously higher than that of the prognosis was good ,compared with statistical significance difference ( P <0.05 );In myocardial infarction group , unstable angina pectoris group , the hsCRP was associated with positive correlation exists between UA (P<0.05),stable angina pectoris group no correla-tion(P>0.05);Different prognosis in patients with myocardial infarction hsCRP is associated with UA has positive correlation between ( P<0.05) .Conclusion Elderly acute myocardial infarction patients serum hs-CRP,UA obviously increased ,and illness development correlation ,a high level of hs-CRP,UA patients often indicates poor prognosis .

Objective To evaluate the role of phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2) in 17β estradiol-induced inhibition of propofol-caused neuroapoptosis in the hippocampus of newborn rats.Methods Seventy-eight male Sprague-Dawley rats,aged 7 days,weighing ll-18 g,were divided into 6 groups (n =13 each) using a random number table:dimethyl sulfoxide (DMSO) group,fat emulsion group (group F),17β estradiol group (group E),propofol group (group P),propofol plus 17β estradiol group (group PE) and propofol plusl7β estradiol plus mitogen-activated protein kinase kinase 1/2 inhibitor U0126 group (group PEU).17β estradiol 600 μg/kg was injected subcutaneously every 24 h for 7 consecutive days in group E,and the equal volume of DMSO was given instead in group DMSO.Propofol 75 mg/kg was injected intraperitoneally every 24 h for 7 consecutive days in group P,and the equal volume of fat emulsion was injected instead in group F.Propofol 75 mg/kg was injected intraperitoneally,and 17β estradiol 600 μg/kg was injected subcutaneously every 24 h for 7 consecutive days in group PE.Propofol 75 mg/kg was injected intraperitoneally,17β estradiol 600 μg/kg was injected subcutaneously,and U0126 10 mg/kg was injected intraperitoneally every 24 h for 7 consecutive days in group PEU.At 15 min after the last injection,3 rats in each group were randomly selected,and arterial blood samples from the cardiac apex were collected for determination of arterial oxygen partial pressure.The animals were sacrificed at 24 h after the last injection for determination of the expression of activated caspase-3 (by immunohistochemistry) and p-ERK1/2 (by Western blot).Results There was no significant difference in arterial oxygen partial pressure between the six groups (P＞0.05).Compared with group F,the expression of activated caspase-3 was significantly up-regulated,and the expression of p-ERK1/2 was downregulated in group P (P＜0.05).Compared with group P,the expression of activated caspase-3 was significantly down-regulated,and the expression of p-ERK1/2 was up-regulated in group PE (P＜0.05).Compared with group PE,the expression of activated caspase-3 was significantly up-regulated,and the expression of p-ERK1/2 was down-regulated in group PEU (P＜0.05).Conclusion The mechanism by which 17β estradiol inhibits propofol-caused neuroapoptosis in the hippocampus is related to up-regulation of the expression of p-ERK1/2 in newborn rats.

Objective To investigate the expression of matrix metalloproteinases(MMP) related to oncogene C-myc and tumor differentiation of cutaneous squamous cell carcinoma (CSCC). Methods Expression of MMP2,MMP9 and C-myc was detected by immunohistochemistry in 68 paraffin embedded specimens of CSCC. Results Distribution of MMP2 and MMP9 was demonstrated within cytoplasm of tumor and stromal cells, especially for those cells at the interface of tumor and interstitial tissues. No expression of MMP2 and MMP9 was observed in the horny centers of tumor cell nests. Expression of MMP2 and MMP9 increased along with the decreasing of the differentiation of tumor tissue and the increasing of C-myc expression. Conclusions Expression of MMP2 and MMP9 might be a common event for both tumor and stromal cells but parenchymal tumor cells might predominate over the activation of MMP2 and MMP9. Oncogene C-myc protein might promote the secretion of MMP2 and MMP9 by tumor cells.
