Objective To explore the indication of implant prosthesis immediately after removing polyacrylamide hydrogel for augmentation mammaplasty. Methods MRI and pathologic examinations were made in 226 patients with the postoperative complications of augmentation mammaplasty by injecting polyacrylamide hydrogel and with the specific conditions in operation to analyze the possibility of implant prosthesis while removing polyacrylamide hydrogel. Based on MRI examination, physical examination and specific conditions in operation, we chosen 61 cases who requested for implant prosthesis while removing polyacrylamide hydrogel. Results The patients who did the operation for simply removing polyacrylamide hydrogel recovered well and symptoms such as pain, sclerosis, mass and others disappeared almostly; the patients who did implanting at the same time were satisfied with the breast shape and had no side-effect occured. Conclusion With MRI examination, physical examination and specific conditions in operation, it can achive good effects to do implanting immediately after removing polyacrylamide hydrogel for those suitable and willing to implant prosthesis.

Objective To observe the correlation between CD64 index levels in peripheral blood and the severity and prognosis factors of postoperative traumatic sepsis,and investigate the clinical effect of these changes in the development of postoperative traumatic sepsis.Methods A total of 560 patients with trauma were enrolled in the study,and these patients were divided into the postoperative traumatic sepsis group (210 cases) and the postoperative general trauma group (350 cases) according to clinical manifestations.According to the severity of the postoperative traumatic sepsis,these patients were divided into low-risk group (64 cases),moderate-risk group (75 cases) and high-risk group (71 cases).According to clinical prognosis,these patients with post-traumatic sepsis were divided into survival group (178 cases) and death group (32 cases).The CD64 index in peripheral blood and APACHE Ⅱ score were analyzed and measured by flow cytometry.The differences and correlation between CD64 index levels and APACHE Ⅱ score were compared and analyzed,and the relationship between CD64 index levels and the severity and prognosis of postoperative traumatic sepsis were also assessed.Results The CD64 index levels of postoperative traumatic sepsis group were higher than the postoperative general trauma group (P<0.05).The differences in terms of CD64 index,APACHE Ⅱ score and mortality rate among low-risk group,moderate-risk group and high-risk group were statistically significant,in which high-risk group was the highest,followed by moderate-risk group,and low-risk group was the lowest(P<0.05).Compared with the survival group,the death group had higher CD64 index levels and APACHE Ⅱ score (P<0.05).The CD64 index levels were positive correlated with APACHE Ⅱ score (r=0.72,P=0.00) and mortality (r=0.56,P=0.00).ROC curves analysis results showed that the area under curve of CD64 index was 0.874 (95%CI:0.765~0.896), and the optimal operating point was 7.08,which had 82.6% sensiticity and 86.4% specificity.Conclusion The increased CD64 index levels in postoperative traumatic sepsis are closely related to the severity and prognosis of disease,and the CD64 index levels can be effective predictor with some clinical application value.

OBJECTIVE:To study the liver damage mechanism in mice caused by the incompatibility of Daphne genkwa com-bined with Glycyrrhiza uralensis in aspect of liver transporter. METHODS:40 mice were equally randomized into a normal control (isometric normal saline)group,a group of G. uralensis [15 g(medicinal matierias)/kg],a group of D. genkwa [15 g(medicinal tatierias)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶1 [15 g(crude drug)/kg],a group of D. genkwa with G. uralensis in the ratio of 1∶3 [15 g(medicinal matierias)/kg](n=8). The mice were given the corresponding drug,ig,once a day for 7 consecutive days. HE staining was performed and then the pathomorphology of liver tissues were observed under the light mi-croscope,and calculation was made for pathological grading. Western blot method was employed to determine the protein expre-ssion of the transporter Ntcp protein in the livers of mice. The contents of total bile acids(TBA)in livers of mice were determined. RESULTS:Compared to the mice in the normal control group,those in the group of 1∶1 and 1∶3 demonstrated higher protein ex-pression of Ntcp. In the group of 1∶1,the mice with grade“+++”hepatocyte degeneration were more (8). The mice with grade“+++”and“++”hepatocyte degeneration in the groups of 1∶3 were more (2 and 8 respectively). CONCLUSIONS:D. genkwa combined with G. uralensis can induce liver damage in mice by a mechanism which may be related to the accumulation of a large amount of TBA in the liver as a result of the increase in the expression of Ntcp in mice.

Objective To study the changes and the significance of the frangible lymphocyte in patients with fulminant viral hepatitis and investigate the relationship between the degree of frangible lymphocyte and the severe of fulminant viral hepatitis. Methods 32 cases confirmed with fulminant viral hepatitis, 66 cases with chronic hepatitis have been studied. 15 cases children from 3 to 5 years old and 46 cases adults have been used with control groups. 100?l lymphocytes (1?106/ml) and 100?l tumor cells(1?105/ml) mixed with 100?l self-serum at 37℃ for 5min to 30min. The fragmental lymphocyte can defined as a frangible lymphocyte. The lymphocyte attached with tumor cell is undestroyed anything can be regarded as negative frangible lymphocyte. Less than 30 percent of lymphocyte attached with tumor cells is destroyed will be conformed as low-grade frangible lymphocyte, between 30 percent to 60 percent regard as mid-grade, and more than 60 percent as severe-grade mode. Results The equiform frangible lymphocyte is detected in fulminant viral hepatitis and other groups like that in SARS in 2003 years. There is none of children have frangible lymphocyte. Only 3 person’s lymphocytes show severe-grade frangible and 9 people display mid-grade in 46 adult individuals. Contrarily There is high of 46.9 percent of cases with fulminant viral hepatitis show severe-grade frangible lymphocytes, only 4 cases is negative and 3 cases is recovered in one months of them. The frangible lymphocytes in fulminant viral hepatitis are significantly lower than those in chronic hepatitis patients not only in mid-grade frangible but in severe type. There is no significant recovery of frangible lymphocyte from acute to recover in fulminant viral hepatitis, but the degree of the lymphocytes are closely relate to the state of an illness. Conclusion The percent of frangible lymphocytes in children is lowest among adult people, chronic hepatitis and fulminant viral hepatitis. The proportion of frangible lymphocytes in fulminant viral hepatitis is highest, and significantly higher than that in chronic hepatitis. The phenomenon of frangible lymphocytes may be an important characteristic of an innate immunology reaction of the body.

M ethods:C-myc expression was determined by SP method in 37 cases of sarc oma and 14 benign mesenchymal tumors in oral and maxillofacial region. R esults:C-myc expression was detectd in 22 cases (40.54%) of sarcoma and in none of the benign tumor. In sarcoma of gradeⅠ, Ⅱand Ⅲ, the positive r ates of C-myc expression were 16.70%, 30% and 66.67% respectively, and a statis tical significance was only observed in C-myc expression between gradeⅠand Ⅲ( P

Mammalian target of rapamycin (mTOR) plays an important role in the regulation of cell proliferation,growth,energy metabolism and so on.Clinical research demonstrate that many tumors have its excessive expression, and the mTOR inhibitors rapamycin can resist the development of gastric cancer.Research of mTOR signaling pathway combined with its upstream and downstream has larger value for the early diagnosis,monitoring curative effect and prognosis.

High mobility group box-1 (HMGB1) is a nonhistone nuclear protein.Normally,as one component of the chromatin,HMGB1 regulate life activities such as genetic transcription,recombination and gene repair.HMGB1 can be realeased to the outside of the cell,which can be bound up with cells multiplication,differentiation,migration and the growth of nerve axon.Studies show that HMGB1 is correlated with tumor (s) occurrence,development,invasion and metastasis,such as lung cancer,colorectal cancer,pancreatic cancer and so on.The studies about the relativity between HMGB1 and gastric cancer play an important role in the diagnosis and treatment of gastric cancers.

Objective To analyze the related factors of local recurrence in patients with rectal cancer after Dixon operation. Methods A retrospective analysis of clinical data of 100 patients from September 2005 to September 2007 in our hospital by TME standard surgicai treatment of low rectal cancer was carried out. Results Of 100 patients, the pre-sacral recurrence rate was 10. 0%, with gender, age, tumor size, tunor invasion lumen circumference,depth of invasion,lymph node metastasis and Duke's stage has nothing to do with the gross type,histological type and lumen,peritoneal tumor cell shedding,and as an independent prognostic factor. Of 90 patients without local recurrence,the 5-year survival rate was 76. 0% ,haff of the survival of 62 months;10 cases of local recurrence,5-year survival rate was 5. 0%, half of the survival of 24 months, suggested that local recurrence in patients influenced the prognosis. Conclusion The low local recurrence of rectal cancer related factors were gross type,histological type and the intestine, peritoneal tumor cells shed, seriously affect the prognosis of patients with local recurrence.
