Objective To study the histopathological features, diagnosis criteria, the relationship of surgery pattern and prognosis of phyllode tumor of breast. Methods To analyze the histopathological features and clinical outcome of different surgery patterns in 203 patients with phyllode tumor of breast by Chi square test, Cluster, Focater, Logistic and Cox multivariate regression according to the request of SPSS 10. 0. Results 203 patients with phyllode tumor of breast were divided into three groups, i.e. benign 133 cases, borderline 42 cases and malignant 28 cases. Local recurrences in three groups were 28, 19 and 18, respectively. The patients died from tumor were 0, 2 and 16, and circulatory metastases were 0, 1 and 10, respectively. Five-year survival were 100 %,92. 0% and 33. 3% in the three groups of 131 patients by a 5 years' follow-up survey. Conclusions Tumor necrosis has important value in the diagnosis of phyllode tumor. Nature of tumor margin, cellular pleomorphism, frequency of mitoses and tumor necrosis were statistically appropriate composition in histological diagnosis of phyllode tumor. Wide local excision is preferred for the benign and borderline phyllode tumor, while simple mastectomy is indicated for recurred borderline and malignant, but tylectomy should be abolished in the treatment of phyllode tumor. Correlation of histotypes of phyllode tumor with local recurrence and tumor death was statistically significant at a level of P＜0. 001; correlation of infiltrative growth of the tumor with local recurrence was statistically significant at a level of P＜0. 001. Tumor necrosis and mitotic activity were independent prognostic factors.

Objective To explore the influence of body position intervention combined with lying position logo on the compliance of patients after vitrectomy needing to keep lying position. Methods A total of 100 patients, who were hospitalized in ophthalmology ward from January to June 2013,received vitrectomy combined with gas or silicone oil filled were involved. All the patients were divided into intervention group (60 cases) and control group (40 cases) according to the order of admission. Patients in control group received routine nursing after retinal vitreous operation, guiding the proper way to keep lying position, putting a sponge pillow, shaping凹, under patients′heads. And some pertinence measures were applied in intervention group on this basis. Results The percentage of the patients who could keep the special position complying with doctor's orders at 72 h and 1 week after the operation were 95.0%(57/60),91.7%(55/60) in intervention group, which were greater than those in control group 80.0%(32/40),75.0%(30/40), and there were significant differences,χ2=4.090,4.003,P<0.05.The mastery of the body position, and the satisfaction of the nursing care were 96.7%(58/60), 98.3%(59/60) in intervention group, which were better than those in control group 77.5%(31/40), 85.0%(34/40),and there were significant differences, χ2=7.154, 4.666,P <0.05. Conclusions Developing a reasonable nursing plan depending on the body position intervention and relevant nursing measures can help the patients comply with doctor's orders effectively, improve comfort,and extend the time to keep the special position,so as to improve postoperative recovery and ensure the success of the operation.

ObjectiveTo study the treatment and prognosis of the breast phyllodes tumors.MethodsKG1Clinical data, and the results of follow-up in 203 cases of breast phyllodes tumors were analyzed using Logistic analysis and Cox regression in SPSS statistic software.ResultWT5”BZLocal recurrence and tumor mortality were in direct proportion to the pathologic grade of the tumor. There was a direct proportion between local recurrence and tumor infiltration; and between tumor caused-mortality and tumor mitosis and necrosis.Mitotic activity and tumor necrosis were the independent prognostic factors. After surgical resection 21 1% of patients with benign tumor, 45 2% of patients with borderline tumor, 64 3% of patients with malignant tumor suffered recurrence. The 5-year survival rate was 100% in patients with benign phyllodes tumor, 92 0% with borderline tumor, and 33 3% with malignance.KG2Conclusion Local excision is not the appropriate treatment for phyllodes tumor. Patients with benign or borderline phyllodes tumor should undergo wide local excision including a margin of uninvolved tissue, and that with local recurrent borderline and malignant phyllodes tumor receive mastectomy.

OBJECTIVETo study the relationship between pathological features and classification criteria of the breast Phyllodes tumor.

METHODS203 cases of breast phyllodes tumor diagnosed in 22 hospitals since 1956 were analyzed and reappraised by a retrospective study.

RESULTS133 cases were benign, 42 cases were borderline and 28 were malignant. The follow-up (6 to 372 months) showed that 28/133 benign, 19/42 borderline and 18/28 malignant cases recurred, and 17 patients (2 borderline and 15 malignant) died. The statistic cluster analysis demonstrated that stromal cellar atypia, margin involvement, mitotic activity and tumor necrosis were retained in the variable group, and no error distinguish were showed.

CONCLUSIONSThe breast phyllodes tumor can be classified as the following three types: benign, borderline and malignant. It is important to diagnose and classify the breast phyllodes tumor according to the involvement of tumor margin, stromal cellar atypia, mitotic activity, stromal overgrowth and tumor necrosis. There are significant differences of 5 years survival rates, recurrent rates and death rates between the benign, borderline and malignant breast phyllodes tumor. With wide excision the recurrence of the tumor decreased suggesting that broad excision is preferred for the benign phyllodes tumor and mastectomy is indicated for recurred borderline and malignant tumors.

Objective Although principal components analysis profiles greatly facilitate the visualization and interpretation of the multivariate data,the quantitative concepts in both scores plot and loading plot are rather obscure.This article introduced three profiles that assisted the better understanding of metabolomic data.Methods The discriminatory profile,heat map,and statistic profile were developed to visualize the multivariate data obtained from high-throughput GC-TOF-MS analysis.Results The discriminatory profile and heat map obviously showed the discriminatory metabolites between the two groups,while the statistic profile showed the potential markers of statistic significance.Conclusion The three types of profiles greatly facilitate our understanding of the metabolomic data and the identification of the potential markers.

OBJECTIVETo evaluate the efficacy of combined modality treatment and determine the prognostic factors for small cell lung cancer (SCLC).

METHODSFrom January 1974 to December 1995, 1260 patients with SCLC treated were retrospectively evaluated, with limited lesions in 732 patients, extensive lesions in 500 and stage unrecorded in 28. 553 patients were alloted into chemotherapy + radiotherapy (C + R) group, 355 into C + R + C group, 97 into R + C group, 126 into C group, 64 into R group and 65 into surgery (S + C + R) group. Patients with limited lesions received 2 - 4 cycles of chemotherapy including COMC, COMP, COMVP and CE-CAP. Radiotherapy was given to a dose of 40 - 70 Gy/4 - 7 w. Radiation portals for patients with limited lesions encompassed the primary tumor, hilar lymphatic drainage areas, partial mediastinum and bilateral supraclavicular regions. Patients with extensive lesions mainly received chemotherapy with or without palliative irradiation.

RESULTSThe overall CR and PR rates were 26.7% and 52.3%. Local recurrence and distant metastasis rates were 58.8% and 61.5%. The 1-, 3- and 5-year survival rates were 50.2%, 14.7% and 11.7%, with median survival time of 12 months. The era, sex, age, tumor stage and treatment modality were all significant prognostic factors by both uni-variate and multi-variate analyses (P < 0.05). The result of S + C + R rated the best among these modalities and the result of C + R + C was superior to C + R, though the difference of which was not significant.

CONCLUSIONSurgical resection should be considered as one part of comprehensive therapy for small cell lung cancer patients with limited lesions whenever possible. On top of routine chemotherapy early administration of radiotherapy is advisable.

OBJECTIVETo detect the contaminating minimal residual disease (MRD) in autologous peripheral blood stem cells (APBSC) and evaluate its impact on the prognosis of non-Hodgkin's lymphoma NHL patients.

METHODSMinimal residual disease was detected in 72 APBSC samples from 33 NHL patients through PCR or PCR combined with DNA single-strand conformation polymorphism analysis (SSCP) with the BCL-2/IgH, clonal rearrangement of IgH and TCR gamma gene as markers. Minimal residual disease was also monitored in bone marrow samples collected pre-, post-induction chemotherapy and post-transplantation.

RESULTSMRD was positive in 17/72 (23.6%) APBSC samples. The incidence of positive MRD in bone marrow pre-, post-induction chemotherapy and post-transplantation was 44.0% (11/25), 28.1% (9/32) and 11.5% (3/26) respectively. Six (66.6%) of 9 patients with positive MRD in pre-mobilization bone marrow, compared with 2 (8.7%) of 23 patients with negative MRD in bone marrow, were positive in contamination (P < 0.01). The estimated overall 3-year post-transplantation survival rate for patients with positive and negative MRD in their APBSC would be 71.4% and 71.2% respectively, and the estimated 3-year disease free survival rates of 25.0% and 61.5% respectively (P = 0.53).

CONCLUSIONAPBSC collected from NHL patients after mobilization by chemotherapy combined with colony stimulating factor may be contaminated by lymphoma cells. The presence of minimal residual disease in bone marrow at mobilization may increase the incidence of APBSC contamination.

Plague is a virulent infectious disease caused by Yersinia pestis. There have been three plague pandemics in the world history, of which the third plague pandemic started in Yunnan, China in 1772, and became a global pandemic in 1894, affecting many countries in Asia, Europe, America, Oceania and Africa. It has been reported that the third plague pandemic was caused by the branch of Yersinia pestis 1.ORI. This paper summarizes the origin, transmission route, distribution area and ecological environment of 1.ORI clade and the relationship with the third plague pandemic, which has guiding significance for further understanding and studying the epidemiological pattern of plague, formulating appropriate surveillance programmes and prevention and control measures.

Objective:To explore the biochemical characteristics, virulence factors and other phenotypes of the strains of Yersinia pestis isolated in Jianchuan County Yunnan Province in 2017, and to analyze the nature and source of the new plague epidemic. Methods:Three strains of Yersinia pestis (JC109 rat, JC109 fleas and JC113) isolated from Daqing Village, Jinhua Town, Jianchuan County, Dali Prefecture, Yunnan Province in 2017, and 2 associated strains of Yersinia pestis (LJ01 in Yulong County, Lijiang City and LJ04 in Gucheng District of Lijiang City), 5 control strains ( Yersinia pestis JC1332, LJ485, BN2636, EV-76 and Yersinia pseudotuberculosis PST-1), preserved by the Central Laboratory of Yunnan Institute for Endemic Disease Control and Prevention were collected. The biochemical characteristics and ecotypes of Yersinia pestis were analyzed by using arabinose, rhamnose, denbiose, maltose and glycerol fermentation experiments and nitrate reduction experiments. Combining pigmentation factor (pgm), virulence antigen (VW) detection and nutritional requirements test results to determine the virulence of Yersinia pestis. Results:The Yersinia pestis JC109 rat, JC109 fleas and JC113 all fermented arabinose, maltose and glycerol, but didn't ferment rhamnose and denbiose; and the nitrate reduction test was positive. The ecological type belonged to the Himalayan Marmot plague strain of Qinghai-Tibet plateau. The virulence factors pgm and VW tests were positive, the nutritional requirement type was phenylalanine dependent and glutamate independent. It had the same phenotype as the LJ01 strain, but different from the JC1332 strain. Conclusions:The newly isolated strains in Jianchuan County are the same as those in the Lijiang Yulong wild rodent plague foci. This outbreak may have been imported from the Lijiang Yulong wild rodent plague foci to the south.

Objective:To study the basic situation of Yunnan Province Suncus murinus carrying plague phage and to explore its epidemiological significance. Methods:From 2015 to 2018, a survey of plague host animals was carried out in 10 investigation sites in the historical plague foci, new plague foci (after 1982) and stubborn plague foci of domestric mouse in Yunnan Province. The plague phage was isolated and cultured from the intestinal specimens of Suncus murinus. The growth of plaque was observed by double-layer plate method, and the morphology and structure of plague phage were observed under electron microscope. At the same time, intestinal samples were taken to detect the structural gene caf1 of F1 antigen of Yersinia pestis. Results:In this study, a total of 157 Suncus murinus were captured and 16 strains of plague phage were isolated, with a total isolation rate of 10.19%. There was no difference in plague phage isolation rate between historical plague foci (10.00%, 1/10) and stubborn plague foci (16.22%, 12/74), new plague foci (4.11%, 3/73, χ 2 = 0.00, P = 0.965; Fisher test, P = 1.000). However, there was a difference in plague phage isolation rate between stubborn plague foci and new plague foci (χ 2 = 5.88, P = 0.015). There was no significant difference in the isolation rate of plague phage among different sex, growth period and habitat ( P > 0.05). The plaque morphology of the isolated plague phage was diverse, of which four strains were myotavirus phages; and all samples were negative for F1 antigen structural gene caf1. Conclusions:Suncus murinus is widely distributed in the domestic mouse plague foci in Yunnan Province, and the animals carry a certain number of plague phage. Regular surveillance of Suncus murinus and their plague phage has a certain guiding significance for the surveillance and early warning of plague in Yunnan Province.
