Objective To identify the reason and preventive methods from misdiagnosed cases of multiple myeloma(MM) initially manifested as lumbago.Methods Medical history and clinical data of 25 MM patients in department of hematology in our hospital were retrospectively analyzed to explore the clinical characteristics,misdiagnosis and prognosis of them.Results The 25 patients with initial presentation of lumbago were most misdiagnosed as bone and joint diseases,including 6 cases of lumbar disc,7 cases of lumbar compression fractures,6 cases of osteoporosis.And 1 cases of bone tuberculosis,3 patients of rheumatoid arthritis.And there were 2 cases of bone metastases,who were later diagnosed when anemia,neutropenia,thrombocytopenic and renal dysfunction appeared.The average misdiagnosed time was 7 months with a range of 3 months to 13 months.The median survival time was (29.2 ± 5.2) months in this group of patients.Conclusion MM,with the first manifestation of lumbago,has a single clinical manifestation and is often misdiagnosed as bone and joint diseases.Specialists who are not from hematology department should raise awareness and vigilance of the disease.Laboratory examinations results should be referred to in the diagnosis.Sum up experience in order to improve the early diagnosis of this disease and to effectively improve patient's prognosis and quality of life.
3.Tumor markers for early diagnosis of human hepatocellular carcinoma
Journal of International Oncology 2011;38(4):296-300
Early detection of HCC is critical for a good prognosis. Therefore, the development of tumor markers that can detect HCC at even earlier stages is urgent. Recent researches show that the human cervical cancer oncogene, gamma-glutamyl transferase mRNA, human telomerase reverse transcriptase mRNA, the proteins such as glypican-3, golgi protein 73, vascular endothelial growth factor and transforming growth factor-β1 could serve as markers for early detection of HCC.
4.Suppression of Growth and Tumorigcnicity in Human Gastric Cancer Cells by the Introduction of Exogenous p53 Gene
Chinese Journal of Cancer Biotherapy 1994;0(01):-
The p53 gene is one of the most common targets for genetic abnormalities in human tumors. Restoring wild - type p53 gene (wt-p53) into cancer cells which have p53 deletion is a strategy in cancer gene therapy. In order to explore the feasibility of this hypothesis, we selected a gastric cancer cell line BGC823 which was confirmed having deletion of chromosome 17pl3 and decreased expression level of p53 mRNA . We transfected construct pC53SN3 containing wt - p53 into BGC823 cell line with lipofectin mediated gene transferration, and G418 resistant colonies were characterized by using analysis of PCR, Southern blot hybridization, Northern blot hybridization and Western blot hybridization. These data showed that exogenous wt-p53 had successfully transferred into BGC823 cells and obtained high expression. The cell growth rates in regular medium and soft agar were inhibited from 30 to 40 percent in the BGC823 cells transfected with wt - p53. The tumorigenicity in nude mice showed that one of four mice failed to form tumor and three of them delayed to form tumor from 7 to 14 days comparing with monk and parent BGC823 cells. These results suggested that exogenous wt -p53 could suppress the growth ability and tumorigenicity of human gastric cancer cells. The method of using lipofectin mediated wt-p53 gene transfection may have a potentially therapeutic effect on human gastric cancer.

Objective To investigate the rule of the aquaporin 4 (AQP 4) expression in the acute ischemic cerebral tissues, and to study the molecular biologic mechanism of diffusion weighted imaging (DWI). Methods Thirty six Wistar rats were divided into 2 groups randomly, including control group ( n = 12) and operation group ( n =24). The operation group was studied after the right middle cerebral artery was unilaterally occluded (MCAO) at an interval of 15 min, 30 min, 1 h, 3 h, 6 h, and 24 h, respectively ( n =4 for each sub group). The operation process of the control group was the same as the operation group except MCAO. All rats in both groups were examined with DWI. The relative ADC (rADC), relative density (rd), and relative area (rs) of the biggest hyperintensity signal layer on DWI were measured. After that, the animals were sacrificed and perfused with the mixture solution consisting of TTC at different time intervals. The biggest layer of the ischemic cerebral tissues stained with TTC and corresponding to that of DWI was examined with immunochemistry and in situ hybridization. The AQP 4 expression AQP 4 (△S and ?) was measured with the Image Analyzer. Meanwhile, histologic examination was performed at each group. Results There was no significant change of the DWI and the pathology, as well as the AQP 4 expression in the control group. In the operation group, abnormal high intensity was found in DWI of ipsilateral MCA territory at 15 min after MCAO, and rADC value decreased quickly within 1 h after MCAO, while the AQP 4 expression, the rd DWI, and the rs DWI increased rapidly in the stage. With the progress of the time, the rADC value further decreased at 3 h, and then began increasing slowly till 24 h . But the AQP 4 expression (△S and ?) and the rd as well as the rs continuously increased slowly between 1 h and 6 h after MCAO, then they had an increasing peak except the rd. The AQP 4 expression, rd DWI, and rs DWI all showed positive linear relationship with time, presenting as 2 peaks and a plateau. The corresponding sequential pathologic changes were gradual increase of intracellular edema (

Tianjin Medical Journal 2016;44(3):373-376
Objective To investigate the symptoms of diarrhea and the behavior of medical treatment after diarrhea in 2013 in Tianjin City, and provid background information for the future population monitoring. Methods A stratified sam?pling method was used to investigate the symptoms, medical treatment and self medication behavior of 4028 residents in Tianjin. Results The number of people who had diarrhea in 2013 was 324, and the incidence rate of diarrhea was 8.04%. Diarrhea was mainly occurred in May-October (n=241, 74.38%). The incidence of diarrhea was the highest in 60-74 years old group, followed by 75-years old and 0-14 years old groups. The incidence of diarrhea was the lowest in 15-29 years old grouop. A total of 121 patients with diarrhea chose to go to hospital (47.08%), 78 patients chose to buy medicine for treat?ment (30.35%) and 58 patients did not do any disposal (22.57%). Among the patients with diarrhea, the highest proportion of patients chose to go to the first grade and the following medical institutions (68.59%, 83/121). There were 14.05%(17/121) and 17.36%(21/121) patients chose to go to the second and the third levels of medical institutions for the treatment. The av?erage cost for patients with diarrhea was 60 (20, 200) yuan. The purchasing expenditure median was 20 (11,50) yuan. The medical spending was more than the purchase of medicines (Z=2.412, P<0.05). The average cost of medical treatment was more higher in the second and the third levels of medical institutions than that of the first medical institution ( Z=50.709,P<0.05). The average cost of medical treatment was in turn increased for patients with diarrhea treated in Baodi county, Xiqing county, Hangu county and Heping county (Z=74.282,P<0.05). There was no statistical significance in medical expenses be?tween patients with different ages and patient with or without medical insurance. Conclusion There are high incidence of diarrhea in patients under 15 years old and patients over 60 years old. Residents suffering from diarrhea mainly choose their own medicine and the treatment in the first and following medical institutions.
