Journal of Chinese Physician 2001;0(06):-
Objective To study clinical characteristics of the patients with enosinophilic gastroenteritis(EG) and analyze the cause of misdiagnosis.Methods 6 cases of EG were analyzed in clinical characteristics,laboratory tests and endoscopy.The clinical characteristics of EG and the possible cause of misdiagnosis were studied.Results ⑴EG have a various clinical manifestation.The mucosal type have the commonest symptoms,such as epigastric pain,diarrhea.The serosal type was presented with abdominal pain,bloating.and ascites,accompanied with nausea,vomiting and low fewer.The patients in the muscular type had bowel obstruction symptom.⑵Enosinophilic counts in peripheral and bone marrow had high level(43 5?20 5)%,and it was related with condition of illness.⑶ESR,CRP and FIB were in normal range,but the IgG was low level.⑷The ascites were effusion with eosinophilia.⑸Endoscopies showed erosion and edema in antrum,duodenum and cecum,accompanied with eosinophilia infiltration in mucosa.⑹The steroid hormone therapy responsion was sensitive and all symptoms were relieved and eosinophils was recovered to normal value within one week.⑺Though their symptom recurrence was probable,good prognosis was got.Conclusions The key point for diagnsos is eosinophilia counts in peripheral blood and ascites.The biopsy of the gastrointestinal tract mucosa is also very important and helpful.
3.Detection of tumor cell apoptosis in vivo with 99mTc-HYNIC-annexin V after a single dose of radiotherapy
Chinese Journal of Clinical Oncology 2013;(15):883-887
Objective:The aims of this study are to detect the apoptosis of cancer cells after a single dose of radiotherapy with 99mTc-HYNIC-annexin V and to investigate the correlation among early apoptosis, radio-therapeutic dose, and radio-sensitivity. Methods:Ten days after respective inoculations of EL4 lymphoma and S180 sarcoma in their right upper limbs, the mice were randomly divided into imaging group (Group One) and observation group (Group Two). In Group One, 99mTc-HYNIC-annexin V was injected via the caudal vein after different doses of irradiation. Approximately 2 h later, clinical imaging was conducted by single-photon emission-computed tomography. The mice were sacrificed to evaluate the bio-distribution of 99mTc in each specimen. Cell count during apoptosis was conducted through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) method. Observation was conducted in Group Two for 2 weeks after the irradiation. Results:Tumor uptake of 99mTc-HYNIC-annexin V significantly correlated with the number of TUNEL-positive cells, which concordantly increased with the increase of dosage (r=0.892, P=0.000). With the same dose (0 or 8 Gy), the values of%ID/g, T/B, T/M, and TUNEL-positive cell number of EL4 lymphoma were significantly higher compared with those of S180 sarcoma. EL4 lymphoma was entirely minimized after irradiation at 8 Gy. Conclusion: 99mTc-HYNIC-annexin V can detect early apoptosis in vivo in tumors receiving radiation. The irradiation-induced apoptosis in vivo determined with 99mTc-HYNIC-annexin V positively correlates with the curative effect of tumors. The detection of tumor cell apoptosis via 99mTc-HYNIC-annexin V helps estimate radio-sensitivity, and can become a predictive index for radiotherapy.
4.The clinical study of red blood cell distribution width in patients with chronic heart failure
Journal of Chinese Physician 2013;15(7):890-894
Objective To investigate the association between red blood cell distribution width (RDW) level and the change of cardiac function in patients with chronic heart failure (CHF) and explore its possible mechanism by studying the correlation between RDW and left ventricular ejection fraction (LVEF),left ventricular end-diastolic dimension (LVEDD),and high-sensitivity C-reactive protein (hsCRP),and uric acid(UA) in patients with chronic heart failure.Methods Two hundred and eighty patients were included in our study.Each patient received the examinations of echocardiography,electrocar diogram (ECG),blood routine,and blood biochemistry.According to the different LVEF,LVEDD and RDW,the patients were divided into groups A,B,C,and D,respectively.The groups were compared with each other.Results According to the different LVEF,from group A to group D,with a progressive decrease in LVEF,RDW level were increased gradually [(13.48 ± 0.85) %,(14.10 ± 1.46) %,(14.59 ±1.59)%,(14.75±1.42)%,F =12.698,P <0.01].There was significant difference among the four groups (P <0.01).RDW level correlated inversely with LVEF(r =-0.538,P <0.01).According to the different LVEDD,from group A to group D,with a progressive increase in LVEDD,RDW level increased gradually [(13.53 ±0.91)%,(14.12±1.42)%,(14.60±1.68)%,(14.76±1.39)%,F =12.276,P <0.01].There was significant difference among the four groups (P <0.01).RDW level correlated positively with LVEDD (r =0.343,P <0.01).In chronic heart failure patients,there were significant linear correlation between RDW and hs-CRP,LgUA (r =0.486,0.513,P <0.05).Conclusions RDW correlated with the change of cardiac function in patients with chronic heart failure.With a progressive decrease in LVEF and a progressive increase in LVEDD,RDW level increased gradually.RDW had a strong correlation with hs-CRP,LgUA.This indicates that RDW level increase may be related to the inflammation and oxidative reaction in patients with chronic heart failure.

Cancer Research and Clinic 2015;27(6):406-408
Objective To investigate the expression of mutant p53,Ki-67,ER and PR in uterine endometrial carcinoma and uterine serous carcinoma,and explore their significance in differential diagnosis.Methods The samples including 37 cases of uterine endometrial carcinoma and 37 cases of uterine serous carcinoma were analyzed.The expression of mutant p53,Ki-67,estrogen receptor and progesterone receptor were performed by using the immunocytochemical (IHC) EnVision system.Data were analyzed with SPSS 11.5 statistic software.Results The positive rate of mutant p53 in uterine endometrial carcinoma was statistically lower than that in uterine serous carcinoma [21.62 % (8/37) vs 64.86 % (24/37) (P < 0.01)].The positive rate of Ki-67 in uterine endometrial carcinoma was statistically lower than that in uterine serous carcinoma [37.84 % (14/37) vs 70.27 % (24/37) (P < 0.01)].The positive rate of estrogen receptor in uterine endometrial carcinoma was statistically higher than that in uterine serous carcinoma [78.38 % (29/37) vs 32.43 % (12/37) (P < 0.01)].The positive rate of progesterone receptor in uterine endometrial carcinoma was statistically higher than that in uterine serous carcinoma [75.67 % (28/37) vs 29.73 % (11/37) (P < 0.01)].Conclusions The expression of mutant p53 and Ki-67 are higher in uterine serous carcinoma.The expression of estrogen receptor and progesterone receptor are higher in uterine endometrial carcinoma.Combined detection of mutant p53,Ki-67,ER and PR has important significance in screening and preventing uterine endometrial carcinoma and uterine serous carcinoma.
7.Progress in the thermoablation of colon cancer with liver metastasis
Chinese Journal of Clinical Oncology 2014;(2):142-146
Thermoablation is a local treatment effectively used to prevent metastasis of colon cancer in the liver and can retain peripheral normal liver tissues. Ablation therapy is less invasive, easier to use, and more repeatable than surgery. This form of therapy also allows the local control of unresectable diseases. Furthermore, thermoablation can be applied as an alternative therapy for small re-sectable lesions in patients who manifest insufficient hepatic function after surgery or those with severe complications. Ablation therapy can artificially increase the surgical margin, thereby increasing the resection rate in patients. Multiple lesions in the liver and surgically inaccessible or unresectable diseases can also be removed. However, several limitations, including the local recurrence of the disease and treatment-related complications in patients, are also observed. The treatment outcome of thermoablation therapy can be further im-proved because this technique is used as a part of multimodality treatment.
8.Sirolimus in kidney transplantation:theory and technology
Chinese Journal of Tissue Engineering Research 2014;(5):779-784
BACKGROUND:Calcineurin inhibitors reduce acute rejection rates and improve short-term graft survival in renal transplantation, but its nephrotoxicity associated with long-term use of calcineurin inhibitors remains an important issue. To both avoid exposure to calcineurin inhibitors and maintain effective immunosuppression, immunosuppressive agents such as sirolimus have emerged.
OBJECTIVE:To summarize the research progress of the two main protocols of sirolimus in kidney transplantation (de novo sirolimus-based therapy without calcineurin inhibitors and protocol conversion from a calcineurin inhibitor based therapy to sirolimus).
METHODS:With the key words of“kidney transplantation, sirolimus”in Chinese and in English, respectively, a computer-based search of articles was performed in CNKI (January 2000 to September 2013) and PubMed (January 1996 to September 2013) databases. Articles with the de novo sirolimus-based therapy without calcineurin inhibitors and protocol conversion from a calcineurin inhibitor based therapy to sirolimus were included.
RESULTS AND CONCLUSION:Sirolimus may obtain the advantages of no renal toxicity, anti-tumor and lower incidence of cytomegalovirus infections when compared with calcineurin inhibitors. But not al patients are suitable for sirolimus, and to screen patients strictly is the key of satisfactory clinical results. An appropriate treatment plan, drug monitoring of sirolimus, prevention and treatment of complications are essential features of the use of sirolimus.
9.Progression of adjuvant radiotherapy upon breast cancer immunity
China Oncology 2014;(5):392-396
Immunity is the basic defense barrier for body, and also closely related to the development, progression, treatment and prognosis of breast cancer. Adjuvant radiotherapy plays an important role in the multidisciplinary treatment of breast cancer. It has long been believed that radiotherapy was immunosuppressive because it could destroy the body’s immune cells directly. While recent studies have shown that radiotherapy can stimulate the host immune system in the antitumor process, including antigen processing, presentation, recognition, and eventually tumor-cell killing. In the clinical aspect, a variety of immune targeted therapies, combined with radiotherapy, have entered clinical trials. The article reviewed research progress and status of the inlfuence of breast cancer adjuvant radiotherapy on antitumor immunity.
10.Advancement and the value of targeted gene related to lung cancer
Journal of International Oncology 2013;40(7):512-515
The occurrence and development of lung cancer are closely related to gene expression and mutations.Recent studies of lung cancer related genes show that the expression of COPS3 gene may play a key role in the lung cancer cell proliferation.Echinoderm microtubule associated protein like 4-anaplastic lymphoma kinase fusion gene and epidermal growth factor receptor mutations coexist.GA733 gene is closely related to lung cancer survival.Fibroblast growth factor receptor 1,high mobility protein family,members of the scavenger receptor class 5 and epidermal growth factor receptor provide new ideas for targeted therapy of lung cancer.For the therapy of lung cancer,multiple gene therapy and gene therapy combined with conventional treatment is required.
