Objective:To investigate the clinical value of total parenteral nutrition for patients with tetanus. Methods:TPN was used in 13 tetanus patients. The nutrition parameters were recorded in these patients and compared with those in 25 tetanus patients without TPN. Results:Compared with the control, body weight, albumin, Hb, peripheral lymphocyte count in TPN group were higher and the complication and mortality were less. Conclusions:Total parenteral nutrition can improve nutrition parameters and prognosis of tetanus patients.

Objective To study the expression of BRG1 gene in colon cancer and its relationship with histological grade and clinicopathological stages characteristics.Methods The expression of BRG1 -positive cancer cells were detected by immunohistochemistry in 100 cases of colon cancer,and the relationship with histological grade and clinicopathological stages characteristics was analyzed.Results Of the 100 colon cancer specimens analyzed,the positive expression rate was 82.0%.The expression of BRG1 in colon cancer tissue with histological grade and TNM staging was significantly different (χ2 =23.509,P =0.024;χ2 =25.659,P =0.002).The higher the histological grade,the stronger the BRG1 expression in colon cancer tissue.BRG1 expression in advanced colon cancer tissue was significantly enhanced in the early stage.Conclusion The appearance of BRG1 -positive cancer cells is associated with histological grade and clinicopathological stages characteristics.BRG1 might play an important role in the development of colon cancer.

Objective: To investigate a new method for improving the therapeutic effect on malignant glioma. Methods: A new type of killer cells, named GS-LAK, was induced by means of costimulating the peripheral ginsenoside(GS) and interleukin-2 (IL-2). Comparing with control group-LAK cells, cytotoxicity of GS-LAK cells against malignant glioma cells(BT325) was examined with MTI method. Results: It showed that GS-LAK cells exhibited some advantages over LAKcells in proliferation, cytotoxicity, as well as the utilizing of IL-2. Conclusion: The application of GS-LAK cells mightopen a new prospect to clinical therapeutic approach to malignant glioma.

Objective:To study the CT manifestations of malignant hepatic perivascular epithelioid cell carcinoma (PEComa).Methods:Clinical data of nine patients undergoing surgery with histologically confirmed malignant hepatic PEComa in Yueqing People's Hospital, Wenzhou People's Hospital, and Yongjia County People's Hospital from January, 2010 to June, 2022 were retrospectively collected, including two males and seven females with a median age of 47 (43, 56) years old. The CT findings, including tumor size, shape, boundary, density, and enhancement patterns, were analyzed.Results:CT scans showed that all nine tumors were single lesions. Five tumors were located in right liver lobe, three in left lobe, and one in caudate lobe. The median tumor diameter was 5.7 (range, 3.3-16.0 ) cm. In terms of tumor shape, three were round, four were quasi-circular, and two were irregular. Eight tumors had well-defined boundaries, while one was ill-defined. Nine tumors showed uneven densities and were lower than the adjacent liver parenchyma. Four tumors had a false capsule, one contained fatty tissue, and six had necrotic and cystic changes. In the arterial phase of contrast-enhanced CT scanning, two tumors showed moderate enhancement and seven showed significant enhancement. In the portal venous and delayed phases, enhancement decreased significantly in four cases, showing a " fast-in and fast-out" pattern. In four cases, the enhancement persisted, showing a " fast-in and slow-out" pattern. One case showed no enhancement in any phase but had a strip-like enhanced vessel inside the tumor. Five cases had significantly thickened vessels around the tumor.Conclusion:The CT manifestations of PEComa are as follows: round or quasi-circular lesions with well-defined boundaries, uneven low densities, significant enhancement in the arterial phase and rapid washout or persistent enhancement in the portal venous and delayed phases.

OBJECTIVE: To investigate the level of formaldehyde in the air of anatomical laboratories and to explore the effect of different prevention measures on reducing the level of formaldehyde. METHODS: The level of formaldehyde in two morphological laboratories of a medical college of a university were measured with a comprehensive atmospheric sampler at different physical ventilation time,different time after spraying biological enzymes and different masks. RESULTS: The level of formaldehyde decreased with the increase of ventilation time in front,middle and back of the laboratory( P < 0. 05).The level of formaldehyde at 30 and 60 minutes after spraying bio-enzymes in three parts of the laboratory was lower than that at 0 minute in the same part of the laboratory( P < 0. 05),and lower than that in the bio-enzymes non-spraying laboratory at the same part and same time point( P < 0. 05). At 0,30 and 60 minutes ventilation time points,the level of formaldehyde in the activated carbon mask group was lower than that in the normal sampling group,the non-woven mask group and the defatted gauze mask group at the same time point( P < 0. 05). CONCLUSION: Both physical ventilation and bio-enzyme degradation can reduce indoor formaldehyde pollution. Active carbon mask can achieve good protection effect.

Objective To study the changes of blood coagulation function in early stage of acute renal failure patients, and illustrate its significance. Methods From October 2011 through January 2013, 80 patients with acute renal failure in the Nephrology Department and Pediatrics Department of Yuebei People’s Hospital were enrolled in this study,50 health people in the same period as control group,then compare the differences in creatinine, blood urea nitrogen, blood platelet(PLT), activated partial thromboplastin time(APTT), prothrombin time(PT), thrombin time(TT), plas-ma fibrinogen (FIB) between the two groups. Results The FIB levels and PLT count in observation group were higher than those of controls group (P<0.05), but APTT,PT,TT showed no statistically significant difference (P>0.05). Con-clusion Hypercoagulabale state could occur in patients with acute renal failure in early stage, abnormal clotting may be participates in occurrence of acute renal failure.
