ABSTRACT
Objective To investigate the relationship between the expression level of heat shock protein B1 (HSPB1) and radiotherapy. Methods We used the gastric cancer data from TCGA. The data was randomly splited to two parts,one as testing data,another one as validation data. Results The results showed that the expression did not associate with overall survival,both on testing and validation data. For patients with high expression of HSPB1,there was no significant different between radiotherapy and nonradiotherapy group. The adjusted HR were 1. 08(0. 38 ～ 3. 09) and 1. 38(0. 53 ～ 3. 64),with P values 0. 89 and 0. 51 for testing and validation data,respectively. Interestingly,for patients with low expression of HSPB1,significant different between radiotherapy and nonradiotherapy group was observed. The adjusted HR were 0. 22(0. 06 ～ 0. 81) and 0. 03(0. 003 ～ 0. 220),with P values 0. 02 and 1. 07 × 10 - 3 for testing and validation data,respectively. Conclusion These results suggest that low expression of HSPB1 strongly associates with radiosensitivity. The survival rate of patients with low expression of HSPB1 after radiotherapy is significantly increased,suggesting that HSPB1 may be a potential molecular marker for precision radiotherapy of gastric cancer.
ABSTRACT
Objective To explore the coincidence rates of positive and reverse blood group of infants younger than six months in Xiamen area in recent years,and to analyze the difference of anti-A or anti-B antibody in infants of different age groups and different ABO blood groups.Methods 2 993 hospitalized infants from 0 to 6 months in five hospitals of Xiamen area were selected.EDTA-K2 anticoagulant blood samples were collected.Micro-column gel agglutination assay was used in ABO blood group.All the infants were divided into six groups,which aged from 0-7 days,8-14 days,15-31 days,1-2 months,3-4 months and 5-6 months.The coincidence rates of positive and reverse blood group of each group were compared.Results Of the 2 993 infants,303 cases were AB type.The coincidence rates of positive and reverse blood group of the other infants which aged from 0-7 days,8-14 days,15-31 days,1-2 months,3-4 months and 5-6 months were 57.0%,61.0%,63.0%,71.8%,84.9% and 91.0%,respectively.The coincidence rates of positive and reverse blood group between different blood groups had no statistically significant difference(x2=0.842,P=0.657).The coincidence rates of positive and reverse blood group had statistically significant difference among different age groups(x2=185.683,P<0.05).Conclusion The IgM antibody of ABO blood group is detected in infants younger than six months.Positive and reverse blood group is necessary in ABO blood group identification of infants to guarantee the safety clinical blood transfusion.
ABSTRACT
Objective To investigate the effects of health education on enhancing the compliance behavior of patients with diabetes mellitus (DM). Methods 63 DM patients were provided with systemic health education during their staying in the hospital. A follow-up interview was performed at the 6th month of discharge to gather the information of how importance of compliance behavior on the prognosis of DM. Result After the systemic health education, the patients could take medicine on time and had a good behavior in daily life, which will effectively improved their quality in the future life.Conclusion Systemic the health education can improve the compliance behavior of patients, and thus directly affects the prognosis of DM.
ABSTRACT
Objective We observed the effect of dexamethasone ointment on preventing phlebitis induced by vinorelbine. Methods Patients with malignant tumor who received chemotherapy of vinorelbine through peripheral superficial vein injection were divided into the observation group (70 cases) and the control group (72 cases) according to the date of hospitalization. All patients received vinorelbine four times averagely. Patients in the observation group was given dexamethasone ointment along punctured superficial vein. Patients in the control group received routine nursing measure. The incidence rate, time and degree of phlebitis was compared between these groups. Results The incidence rate and degree of phlebitis was lower than those of the control group (P< 0.01, P< 0.05). The incidence time of phlebitis in the observation group was also later than that of the control group (P<0.05). Conclusion Local application of dexamethasone ointment could effectively reduce the incidence of superficial phlebitis caused by vinorelbine chemotherapy.
ABSTRACT
Objective To investigate the effect of intratumor injection of 131I-3H11 for gastric cancer (GC). Methods 16 patients with GC subjected to endoscopic intratumor injection of 131I-3H11 as a treatment group; 6 GC patients with FAM chemotherapy as a control group. Histological examination of the postoperative specimens of the two group were comparated. Results In treatment group, 75.0%(12/16) of cases were found to have morphological changes with karyopyknosis, karyorrhexis, coagulation of cytoplasm, and invasion of lymphocyte in mesochyma. Most of these changes were medial; but in control group no obvious morphological change was found. Conclusions The results suggest that GC subjected to endoscopic intratumor injection of 131I-3H11 preoperatively has promising application in the clinic.
ABSTRACT
Objective To investigate micrometastasis in axillary lymph nodes and its relationship with nm23 expression of the tumor tissue in breast cancer patients. Methods Paraffin blocks of 832 surgically removed lymph nodes and carcinoma tissues from 52 lymph node negative cases comfirmed by routine pathology were re examined by immunohistochemical staining using monoclonal anti EMA and anti nm23 H1 respectively. Results Micrometastasis were observed in 12 of the 52 patients (23.0%) and in 34 of the 832 lymph nodes ( 4.1% ). The positive rate of micrometastasis that in the tumor larger than 2.0cm or poorly differentiated was significantly higher than in the tumor
