We analyzed retrospectively the result of postoperative RT by electron beam in 314 patients with breast cancer after a radical or modified mastectomy between 1976～1992. The radiation portals covered the supraclavicular, the axillary and the internal mammary lymph node chains and chest wall. D T40～50Gy/4～5w was delivered. The local regional failure and factors affecting the survival rates, such as the clinical stage, the status of axillary lymph nodes and radiation dose were analyzed. The symptomatic radiation pneumonitis (9.4%) was discussed.

objective To develop long-term care demand assessment indicators for the disabled elderly in nursing home.Methods The assessment indicators were formulated based on literature review,semi-structured interviews and expert meeting.Then,Delphi technique was used to identify the indicators through two rounds of consultation among 23 experts.Results The response rates of two rounds consultation were 74.19％ and 95.65％,and the authority coefficients of experts were 0.850 and 0.905.The coordination coefficients of two levels of indicators in the second round were 0.600 and 0.269,respectively (P＜0.001).The long-term care demand assessment indicators for the disabled elderly in nursing homes consisted of 5 first-level indicators and 40 seeond-level indicators.Conclusion The longterm care demand assessment indicators for the disabled elderly in nursing home is reliable and scientific,which can provide references for further developing long-term care contents for the elderly in the nursing home and standardizing quality of long-term care.

Objective To investigate the risk factors of prognosis of gram-positive bacteria associated nosocomial bloodstream infections,and to investigate the drug resistance of the strains.Methods A total of 132 patients with gram-positive bacteria associated nosocomial bloodstream infections were collected from the First Affiliated Hospital of Zhejiang Chinese Medicine University during January 2010 and December 2012.Clinical data including demographic characteristics,underlying diseases,risk factors and use of antibacterial agents were retrospectively analyzed.According to 28-day prognosis,patients were divided into survival group (n =97) and death group (n =35).Binary logistic regression was used to identify the risk factors of 28-day fatality.Results Among 132 patients,49 (37.12％) were infected with coagulase-negative Staphylococcus,46 (34.85％) were infected with Staphylococcus aureus,37 (28.03％)were infected with Enterococcus.The rates of methicillin resistant coagulase negative Staphylococci (MRCNS) and methicillin-resistant Staphylococcus aureus (MRSA) were 77.55％ (38/49) and 54.35％ (25/46),respectively.The rate of linezolid resistant coagulase negative Staphylococci was 8.16％ (4/49) ; Four out of 37 strains (10.81％) of Enterococcus were both resistant to vancomycin and linezolid.Binary logistic regression showed that septic shock (OR =34.344,95％ CI:6.539-180.389,P =0.000),deep venous catheterization (OR =13.411,95％ CI:1.877-95.832,P =0.010),no catheter removal after infection (OR =8.759,95％ CI:2.197-34.911,P =0.002),parenteral nutrition (OR =3.684,95％ CI:1.072-12.663,P =0.038),inappropriate antibacterial therapy in early stage (OR =12.951,95％ CI:2.075-80.836,P =0.006) and Enterococcus associated bloodstream infections (OR =4.227,95％ CI:1.090-16.394,P =0.037) were independent risk factors of 28-day fatality in patients with gram-positive bacteria associated nosocomial bloodstream infections.Conclusions The predominant pathogens are coagulase-negative Staphylococcus,Staphylococcus aureus and Enterococcus in gram-positive bacteria associated nosocomial bloodstream infections.Patients with septic shock,deep venous catheterization,no catheter removal after infection,parenteral nutrition,inappropriate antibacterial therapy in early stage and Enterococcus associated bloodstream infections are likely to have high fatality rate.

Purpose To investigate the clinicopathological features of multilocular cystic renal cell carcinoma ( MCRCC) , and to im-prove the understanding of this disease. Methods Thirty-two of MCRCC were studied by clinic data, pathological features and immu-nophenotype. All the thirty-two cases were followed up. Results In this study, thirty-two patients were diagnosed as MCRCC with a male-to-female ratio of 2.2 : 1, thirteen of whom had the tumor in the left kidney, eighteen in the right kidney, another in the double kidneys. The mean of tumor diameter was 4.6 cm (1.0~8.0 cm). Eleven patients underwent radical nephrectomy while the other 21 patients received nephron sparing surgery. Microscopically, all the cases were multiocular, lined in the cyst wall by a single layer of tumor cells with the clear or pale cytoplasm and Fuhrman grade 1 nuclei. Occasionally, the lining consisted of several layers of tumor cells or a few small papillae were present. The linings of the cyst wall were rich in thin-wall blood vessels. Immunohistochemically, the tumor cells were positive for CK(32/32), CK7(25/32), EMA(32/32), CD10(23/32) and vimentin(20/32), while negative for CD68. Conclusions MCRCC is characteristic by low grade nuclei, lacking solid nodules, and in the cyst wall, and has a favourable prognosis. The rich in thin-wall blood vessels and the lining cells with the clear or pale cytoplasm are diagnosis clues.

Objective To study MRI manifestations of cerebral developmental venous anomaly (DVA)and to analyze the diagnos-tic value of different sequences.Methods Conventional MRI and contrast enhancement 3D-T1 WI were performed in all 10 patients who were collected in our hospital.Among the 10 cases,6 patients underwent MRA and 4 patients underwent MRV.The diaplay of the draining veins and medullary veins were assessed.Results All 10 cases were sporadic lesion,the lesions of 9 cases were located in supra tentorium and which of 1 case was located in infra tentorium.Abnormal signals without characteristics of draining veins in 6 cases and dilated medullary veins in 4 cases were found in conventional MRI,while 6 draining veins showed flow void signal on T2 WI and 3 of the 4 medullary veins showed hypointensity on T1 WI and hyperintensity on T2 WI.Contrast enhancement 3D-T1 WI displayed the markedly enhanced draining veins and dilated medullary veins in all 10 cases of DVA.Numerous medullary veins gath-ered together into large draining veins radially and flowed into superficial or deeper veins,so-called“caput medusae”appearance were found as the characteristics in all cases.MRA and MRV revealed draining veins only partially but no medullary veins.Conclusion MRI could diagnose DVA clearly,the sensitivity of detecting DVA on conventional MRI is low and there are no characteristics ap-pearances.Contrast enhancement 3D-T1 WI is the most accurate and sensitive method,MRA and MRV are not highly worthwhile for diagnosing DVA.

Objective To study the feasibility of using fractional flow reserve (FFR) to guide whether to perform coronary revascularization of non-culprit moderate stenosis in patients with unstable angina and estimate their clinical prognosis. Methods This study enrolled unstable angina patients with multivessel disease. First successful stenting of the culprit artery, then the other non-culprit moderate coronary stenosis were randomized into PCI guided by angiography or guided by FFR measurements. Death from any cause, nonfatal myocardial infarction, unplanned hospitalization leading to urgent revascularization and clinical manifestations with angina were followed during the first year. Results 71 patients were included, among them 35 patiens were randomly assigned to angiography-guided PCI and 36 patients to FFR-guided PCI. In FFR-guided PCI group, FFR was successfully measured in all of non-culprit moderate coronary stenosis. In 23 stenosis, the FFR was greater than 0.80, and stents were not placed in these stenosis. In 13 stenosis with FFR<0.8, stent were inplant and FFR was raised≥0.95 after stenting. The percentage of patients who had a primary end-point event was higher in the angiography-guided PCI group than the FFR-guided PCI group (P<0.05). Neither the rate of mortelity from any cause nor the rate of non-fatal myocardial infarction had significant difference between the 2 groups. Related to the target vessels rates of nonfatal myocardial infarction (5.6%vs. 28.6%) and target lesion revascularization (5.6%vs. 31.4%) were statistically different (P<0.01 and P<0.05, respectively). Conclusions In patients with unstable angina, it is safe to use FFR values to guide decisions on the revascularization of angiographically moderate non-culprit stenosis. Routine measurement of FFR in addition to angiographic guidance, as compared with PCI guided by angiography alone, results in a significant reduction in major adverse events at 1 year, particularly in urgent revascularization, and clinical manifestations with angina get better.

Objective To discuss The Clinical Significance of Eosinophil (EOS) in urosepsis. Methods A total of 99 patients of urosepsis in Department of Urology,Guangdong Provincial TCM Hospital from Mar. 2013 to Jul. 2016 were selected as research objects by retrospective analysis. The patients were classified into groupEOS= 0 andgroup EOS > 0,group PCT(procalcitonin)≥ 2 ng/mL andgroup PCT < 2 ng/mL,the differences of PCT concentration and percentage of EOS in two groups were analyzed comparatively. 99 patients of urosepsiswere also compared the difference of the percentage of EOS with another group including 100 patients of urinary tract infection (UTI) without Sepsis. Results The percentage of EOS was significantly decreased in 86.9%(86/99)of patients of urosepsis. The paired student t test show the percentage of EOS in two days after treatment,four days after treatment, before hospital discharge were higher than that before the treatment, the difference wassignificant (P < 0.05). The Independent-Sample Test show that the PCTconcentration in EOS = 0 group were higher than EOS > 0 group,the percentage of EOS in PCT≥2 ng/mL groupwere lower than PCT<2 ng/mL group,difference were significant(P<0.05). And The Independent-Sample Testalso showed that the percentage of EOS of the Urosepsis group was definitely lower than the UTI group without Sepsis. Difference was statistically significant. Concusions The percentage of EOS could be applied to assess the severity of urosepsis, monitor the disease progression and evaluate the infection control. The cost was lower than PCT in therapeuticprocess ofurosepsis.

Objective To investigate the causes,diagnosis and treatment of small intestine bleeding.Methods Sixty-eight cases of small intestine bleeding from January 2000 to June 2010 were retrospectively analyzed.Among all cases,4 underwent routine hemostatic treatment under colonoscopy,40treated with open surgery and 24 patients with laparoscopic therapy.Among them,57 cases underwent part resection for some small intestine,completely laparoscopic resection of diverticula was performed in 7patients.Results Neoplasms was the leading cause of small intestine bleeding,accounting for 48.5％ (33/68)in these patients,followed by small intestine diverticulum accounted for 29.4％ ( 20/68 ),intestinal infective diseases accounted for 14.7％ ( 10/68 ) and vascular disease accounted for 7.4％ ( 5/68 ).Conclusion The clinical manifestations of small intestinal bleeding showed no specific signs.Neoplasm,intestine diverticulum and intestinal infective diseases are the most common causes of small intestinal bleeding.Small intestinal bleeding can be diagnosed in intraoperative colonoscopy.Surgery is the most effective treatment for small intestinal bleeding.

A total of 105 patients with first-episode schizophrenia (male =51,female =54) and 99 normal controls (male =51,female =48) were included into this retrospective case-control study.Childhood trauma questionnaire-28 item short form (CTQ-SF) was used to assess the experience of childhood abuse.The result of binary logistic regression showed that emotional abuse (β =0.630,P ＜ 0.05) and emotional neglect(β =0.270,P ＜ 0.05) were included into the final model of predicting schizophrenia.It indicates that patients with first-episode schizophrenia experienced more early life stress than controls.Particularly emotional abuse and emotional neglect may play important roles in the onset of schizophrenia.

Objective To investigate the objective factors that affect the image quality of infant cranial CT using different mAs. Materials and Methods Ninety infants were divided into three groups randomly. The maximum anteroposterior diameter (MAPD) of skull of each infant was measured. Three reference levels, cerebellar, basal ganglia and centrum semiovale levels were selected respectively. Only one level was studied in each group and scanned with 150, 100 and 80 mAs. The subjective quality grade and the objective noise of all images were recorded and analysed statistically. Result The average MAPD of ninety patients was (148.0 ± 17.4)mm. On the cerebellar level, the subjective quality grade was lower than the other two levels, which were 6.3% , 9.4% and 22.9% respectively when mAs were 150, 100 and 80 mAs. Both quality grade of image and objective noise were significantly correlated with MAPD.Conclusion The inherent high noise of cerebellar level and MAPD were the objective factors that affect the image quality of low-dose cranial CT of infant.
