Objective To evaluate the value of magnetic resonance imaging in rheumatoid arthritis(RA) of the knee and compare with radiography.Methods 34 cases of RA of the knee were performed MRI and radiography.Enhanced MRI scans were obtained in 13 knees.Results On MRI there were bone erosion in 34 knees,subchondral sclerosis in 21 knees,meniscus destruction in 22 knees,cartilage damage in 15 knees,tibia movement in 10 knees,posterior cruciate ligament dragged in 8 knees.Pannus adhesion,proliferation synovium and joint effusion were showed on enhanced MRI in all of the 13 knees.On radiography bone erosion was showed in 1 knee,subchondral sclerosis in 11 knees,joint space stricture in 16 knees,tibia movement in 8 knees.Conclusion MRI is much better than radiolgraphy for diagnosis of RA of the knee.

Objective To analyze the influence of different types of seizures and nonepileptic events on peripheral white blood cell (WBC)counts. Methods We prospectively collected blood samples from all patients and detered WBC count to evaluate the relation of each type of seizure,duration,frequencies,and ttme lapse between a seizure and collection of blood sample to peripheral WBC count. Results Peripheral WBC count was elevated in about 50% cases after a generalized seizure. The length of a seizures was positively associated, whereas its frequencies and the lapse time was negatively correlated with the increase in WBC counts. Conclusion Peripheral WBC counts increase significantly after a generalized seizure.

The methods of diagnostic imaging for pulmonary embolism is diversified. However, the different characteristic features of diagnostic imaging and diagnostic accuracy impressive influenced the choice of selection by clinicians. Furthermore, the principle and indication of interventional therapy would have great impending force on the outcomings. This article presents a comprehension of diagnostic imagings and interventional therapy for pulmonary embolization.

Objective To investigate the protein expression of cyclooxygenase(COX)-2 and matrix metalloproteinase(MMP)-2 and their correlation in human gastric carcinoma.Methods The protein expression of COX-2 and MMP-2 was determined by immunohistochemistry in tumor tissues and adjacent cancerous tissues (3 cm and 6 cm away from tumor margin) of 30 patients with gastric cancer,and in gastric mucosa of 10 healthy individuals.Results Expression of COX-2 was found in cancer cells of 26 out of 30 cases (86.67%),which was significantly higher than that in normal control (0 of 10,P

OBJECTIVE:To study the chemical constituents in antioxidant activity part of Semiaquilegia adoxoides. METH-ODS:The antioxidant activity part of S. adoxoides were isolated and purified by chromatography on silicagel and Sephadex LH-20 column,and compound structures were identified physicochemical properties and spectral data analysis. RESULTS:Nine com-pounds were isolated from the antioxidant activity part of S. adoxoides,namely magnoflorine (1),griffonilide (2),salidroside (3),ferulic acid(4),genistein(5),2,4-dihydroxybenzoic acid(6),chlorogenic acid(7),caffeic acid(8)and p-coumaric acid (9). CONCLUSIONS:The study confirms the active material basis in antioxidant activity part of S. adoxoides for the first time.

Objective To evaluate the therapeutic efficacy of neoadjuvant chemotherapy in cervical carcinoma. Methods TAC(DDP, EPI and BLM) was applied in 68 patients with cervical carcinoma. Therapeutic efficacy and side effects were documented. Results After 1～3 cycles of neoadjuvant chemotherapy, clinical symptoms remission rares reached 100% ,response rate were 100% (40/40) in Ⅰ b～Ⅱ a,90.9% (20/22) in Ⅱ b and 50% (2/4)in Ⅲ a, respectively. Radical resection reached 91.2 %, and only 6 patients of advanced disease failed to radical resection and turned to radiotherapy. Conclusion Neoadjuvant chemotherapy is a safe and effective therapeutic option which could alleviate clinical symptoms, decrease tumor size, down-staging and increase the radical resection rate.

Objective To explore the method of culture of rat adipose-derived stem cells(ADSCs) and differentiation induction into myoblasts. Methods Adipose tissues were obtained from SD rats,and were isolated by enzyme digestion and cultured into ADSCs.The expression of surface antigen CD90,CD105 and CD34 was detected by immunofluorescence and flow cytometry.ADSCs of the second passage with logarithmic growth were obtained,and culture media containing 5-azacytidine(5-aza) and basic culture media were employed for cells in induction group and control group,respectively.The induction lasted for 7 d,14 d,21 d,28 d and 35 d,respectively.Cell growth and cell morphology were observed by inverted phase contrast microscope,and immunofluorescence and flow cytometry were utilized to detect the expression of myoblast specific antigens desmin and myosin. Results ADSCs were successfully isolated and cultured,and were identified to be stem cells.On the 28th day of induction,cells in induction group displayed "swirl" morpholgy,and multinucleation was observed.It was revealed by immunofluorescence and flow cytometry that the highest expression rates of desmin and myosin were 52.57% and 50.04%,respectively on the 28th day of induction,while there was no expression before induction and in control group. Conclusion ADSCs can be isolated and cultured from rat adipose tissues,and can further differentiate into myoblasts after induction by culture media with 5-aza.The expression of myoblast specific antigen is the highest on the 28th day of induction.

Objective:To study the effect of early nursing intervention to prevent lymphedema of upper limb after breast cancer surgery and its effect on postoperative quality of life.Methods:Between July 2018 and March 2020, one hundred and seventeen cases of breast cancer, all female, admitted to department of thyroid and breast surgery, the affiliated Zhongshan hospital of Dalian University, were underwent modified radical mastectomy with axillary lymph node dissection. Fifty-eight cases were included in the control group whereas fifty-nine cases were in the intervention group. The control group received conventional nursing, the intervention group added early care intervention measures on the basis of conventional nursing. Follow-ups were carried out monthly in a period of 9 months post-surgery. The incidence and grade of lymphedema were compared between the two groups.Results:The incidences of lymphedema at 1,3,9 months after surgery were 8.5% (5/59), 8.5% (5/59), 10.2% (6/59) in the intervention group, which were lower than 31.0% (18/58), 36.2% (21/58), 43.1% (25/58) in the control group. Statistics showed significant difference between the two groups ( χ2 value was 9.425, 13.041, 16.289, P<0.05). The incidence of mild, moderate, and severe lymphedema were statistically different between the two groups ( χ2 value was 10.350, 12.078, 17.422, P<0.05). Follow-up for the quality of life was assessed using a 5-dimension evaluation method, including physical status, social/family status, emotional status, functional status and additional attention. One month follow-up showed 20.36±1.80, 20.03±1.68, 34.63±3.52, 15.86±1.96, 19.81±1.04 in the intervention group, all higher than the control group 17.03±1.36, 17.10±1.46, 19.38±1.51, 10.91±1.22, 18.36±1.21. Three-month follow-up showed 23.56±2.72, 23.73±2.20, 39.93±4.17, 20.31±3.04, 26.37±2.23 in the intervention group, higher than those of the control group 20.90±2.14, 19.12±2.63, 25.79±3.59, 13.97±2.67, 21.02±2.50. Nine month follow-up showed 27.44±2.01, 25.80±1.85, 40.88±3.72, 21.02±2.78, 27.02±2.45 in the intervention group, which were high than the control group 19.93±1.66, 20.67±1.46, 19.38±2.29, 16.33±2.65, 22.29±2.52. The difference between the two groups were statistically significant ( t value was 8.691-34.383, P<0.05). Conclusions:Early nursing intervention could prevent lymphedema of upper limb after breast cancer surgery, delay the progress of lymphedema, reduce the incidence and grade of lymphedema, and promote the rehabilitation of patients' affected limbs, improve quality of Life of patients, which is worthy of clinical application.
