Objective: To investigate clinicopathological, cytogenetic features and differential diagnoses of high grade endometrial stromal sarcoma (HGESS) with BCOR gene rearrangement. Methods: Five cases of HGESS with BCOR rearrangement were collected from consultant files (2016-2018) at Fudan University Shanghai Cancer Center. Interphase FISH was performed using a dual color break-apart probe. The clinical data, histologic features and immunohistochemical findings were reviewed. Results: All 5 cases occurred in adult women with a median age of 48 (range, 45-55) years. Abdominal pain and abnormal vaginal bleeding were the most common symptoms. Microscopically, the tumors showed mainly tongue-like and/or intersecting myometrial invasion. Stromal myxoid matrix and/or collagen plaques were prominent in all the cases. Most tumors consisted of uniform, haphazard fascicles of short spindle cells with mild to moderate nuclear atypia. Mitotic figures and necrosis were easily identified. Significant nuclear pleomorphism was not seen. Most tumors were rich in thick-walled small vessels. Prominent perivascular tumor cell whorling seen in conventional low-grade endometrial stromal sarcoma was not seen. All tumors expressed CD10 with only focal or absent desmin, SMA and/or h-caldesmon staining. ER or PR expression was seen in 4 tumors and 1 tumor showed both marker expression. Diffuse cyclin D1 was present in 2 tumors. BCOR immunoreactivity was present with strong staining in 3 cases and moderate staining in 1 case respectively. Ki-67 index ranged from 10% to 30%. Fluorescence in situ hybridization confirmed chromosomal aberration of BCOR gene in all tumors, that were previously diagnosed as myxoid leiomyosarcoma (2 cases), spindle cell uterine sarcoma (2 cases) and low-grade endometrial stromal sarcoma (1 case). Limited follow-up information revealed that 3/5 patients developed tumor recurrence, metastasis or death within one year. Conclusion BCOR rearranged HGESS has distinct morphological features and aggressive clinical behavior. In the presence of significant overlapping morphologic features between BCOR rearranged HGESS and other myxoid uterine mesenchymal tumors, especially myxoid leiomyosarcoma, molecular analysis is essential for accurate diagnoses.

Objective To explore the psychological projection on improving the quality of marriage of patients with breast cancer after chemotherapy. Methods From January to December 2015, a total of 32 breast cancer patients with postoperative chemotherapy who admitted to Department of General Surgery Huai'nan North Hospital and Huai'nan Eastern Hospital were selected as the research object. Olson marital quality questionnaire was issued when patients firstly receiving chemotherapy in hospital, at the same time they were evaluated by the Rorschach Inkblot Test. In view of the negative projection in the patient's test, the intervention was carried out by painting projective therapy, sand plate therapy, deep hypnosis and cognitive behavioral therapy. The marital quality of patients were investigated again at 1 month after discharge or the second time receiving chemotherapy. The scores of Olson marital quality questionnaire were compared before and after the intervention. Results Before the intervention of psychological projection, the score of marital satisfaction, husband and wife communication and sexual life dimension in the Olson quality of marriage questionnaire were (33.3±5.6), (30.9±5.5) and (28.2±4.2) respectively. The scores of each dimension after intervention were (36.1±4.6), (34.2±4.3), and (30.7±5.3) respectively. They were all improved in the Olson marital quality questionnaire, and the differences were statistically significant (t=2.19, 2.67,2.09; P<0.05). Conclusions The intervention of psychological projection can relieve the physical and psychological trauma caused by breast cancer in patients with postoperative chemotherapy of breast cancer and improve the quality of marriage.

Objective: To investigate the role of JAZF1 gene rearrangement in the diagnosis and differential diagnosis of endometrial stromal sarcomas by fluorescence in situ hybridization (FISH). Methods: JAZF1 gene rearrangement was analyzed by FISH in 129 cases of ESS diagnosed from January 2008 to December 2016 including 105 cases of low-grade endometrial stromal sarcoma (LG-ESS), 21 cases of high-grade endometrial stromal sarcoma (HG-ESS) and 3 cases of undifferentiated uterine sarcoma (UUS). Sixteen cases of the related tumours in uterus were also collected as control group. The results were compared with our previous studies of JAZF1/JJAZ1 fusion gene in ESS by RT-PCR. Results: Detection of JAZF1 gene rearrangement by FISH was successfully analyzed in 144 cases. JAZF1 gene alteration was detected in 63 cases, all of which were LG-ESS, with an overall positivity of 60.6% (63/104), while no JAZF1 gene rearrangement was found in all other cases. JAZF1 gene rearrangement was present in LG-ESS with classic histology (69.3%, 52/75), smooth muscle differentiation (2/10), sex cord-like differentiation (4/5), fibromyxoid change (1/5), clear cell change (0/1), skeletal muscle differentiation (0/1), and schwannoma-like palisading pattern (0/1). The different components in all the cases of LG-ESS with variant histology had the clonal origin, with or without JAZF1 gene alteration. Compared to the results of JAZF1/JJAZ1 fusion gene by RT-PCR, the positive rate of JAZF1 gene rearrangement in LG-ESS by FISH (61.9%, 26/42) was significantly higher than that of RT-PCR (30.0%, 12/40; P<0.01). Conclusions JAZF1 gene rearrangement is present only in LG-ESS, but not in HG-ESS, UUS or other related tumours in uterus. The frequency of JAZF1 gene rearrangement varies between classic LG-ESS and different morphologic variants. It is frequently, but not consistently, present in classic LG-ESS and less often positive in variant cases. The results of JAZF1 gene alterations in LG-ESS with different morphologic variants support the contention that the endometrial stromal and their variant morphologic components have the same clonal origin. Detection of JAZF1 gene rearrangement by FISH is very useful for the diagnosis and differential diagnosis of ESS.

Background: Metastatic colorectal cancer (mCRC) patients with progressive disease after all available standard therapies need new medication for further treatment. Famitinib is a small-molecule multikinase inhibitor, with promis-ing anticancer activities. This multicenter, randomized, double-blinded, placebo-controlled, phase II clinical trial was designed to evaluate the safety and efficacy of famitinib in mCRC. Methods: Famitinib or placebo was administered orally once daily. The primary endpoint was progression-free survival (PFS). Secondary endpoints included objective response rate (ORR), disease control rate (DCR), overall survival (OS), quality-of-life (QoL), and safety. Results: Between July 18, 2012 and Jan 22, 2014, a total of 167 patients were screened, and 154 patients were rand-omized in a 2:1 ratio to receive either famitinib (n = 99) or placebo (n = 55). The median PFS was 2.8 and 1.5 months in the famitinib and placebo groups (hazard ratio = 0.60, 95% confidence interval = 0.41–0.86, P = 0.004). The DCR was 59.8% and 31.4% (P = 0.002) and the ORR was 2.2% and 0.0% (P = 0.540) in the famitinib and placebo groups, respectively. The most frequent grade 3–4 adverse events were hypertension (11.1%), hand-foot syndrome (10.1%), thrombocytopenia (10.1%), and neutropenia (9.1%). Serious adverse events occurred in 11 (11.1%) patients in the famitinib group and 5 (9.1%) in the placebo group (P = 0.788). The median OS of the famitinib and placebo groups was 7.4 and 7.2 months (P = 0.657). Conclusion: Famitinib prolonged PFS in refractory mCRC patients with acceptable tolerability. Trial registration This study was registered on ClinicalTrials.gov (NCT01762293) and was orally presented in the 2015 ASCO-Gastrointestinal Symposium

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

Objective To study the serotypes,virulence features and molecular characteristics of Vibrio parahaemaolyticus isolated in food poisoning cases and surveillance program on diarrhea patients in Guangdong,2009.Methods 95 Vibrio parahaemolyticus strains from food poisoning cases and 15 strains from surveillance program on diarrhea patients were serotyped and detected for tdh(thermostable direct hemolysin,tdh)and trh(tdh-related hemolysin gene,trh)by PCR.81 sero-variant Vibrio parahaemolyticus strains were selected through PFGE subtyping.Results There were 15 Vibrio parahaemolyticus strains isolated from surveillance program on diarrhea patients and 95 strains were isolated from 11 Vibrio parahaemolyticus-caused food poisoning cases in 2009.Among these strains,O3:K6(46.67％ and 44.21％)and O4:K8(33.33％ and 28.42％)were the dominant serotypes,but not the 7 food-borne strains.There were 93(84.54％)tdh +trh-,13(11.81％)tdh-trh-,and 3(3.65％)tdh+ trh + strains.The similarity value was between 57.7％ to 100.0％ of the 81 strains after PFGE sub-typing method and 36 PFGE subtypes were identified.PFGE001 and PFGE029 appeared to be the dominant subtypes.Conclusion O3:K6 and O4:K8 were the most dominant serotypes in Vibrio parahaemolyticus-caused diarrhea and food poisoning cases in Guangdong and tdh were detected in most of the strains.Dominant PFGE subtypes were causing both sporadic and outbreak cases in different areas in Guangdong province.

Objective To understand the distribution,molecular characteristics and virulence genes of the O1 and O139 Vibrio cholerae isolates from the Pearl River Estuary water.Methods Vibrio cholerae isolates collected from the Pearl River estuary waters from January 2009 to December 2010,were tested by PCR for eight virulence-related genes,including cholera toxin(ctxA),zonula occludens toxin(zot),accessory cholera enterotoxin(ace),hemolysin(hlyA),toxin-coregulated pilus (tcpA),outer membrane protein(ompU),and the regulatory protein genes(tcpⅠ,toxR).Genetic relation was assessed by pulsed-field gel electrophoresis(PFGE)and the patterns were clustered by BioNumerics.Results From 1152 aquatic samples,69 isolates were identified,including 41 Inaba,18 Ogawa and 10 O139.All the isolates showed ctxA negative,while the hlyA and toxR genes were positive in all the isolates.34.15％(14/41)of the Inaba strains were hlyA + toxR + ompU + ace + zot + tcpI+,while 66.67％(12/18)belonged to Ogawa strains and 70％(7/10)of the O139 strains were hlyA + toxR+.Through PFGE analysis,the O1 isolates formed three clusters in this study.The patterns of O1 isolates differed widely,with the similarity as 72.8％-100.0％,while the patterns of O139 isolates having the similarity of 69.9％-95.5％.Conclusion The non-toxigenic O1 and O139 V.cholerae had a wide distribution in the environment of Pearl River estuary water during the nonepidemic period of cholera.All the aquatic isolates presented diversities on the related virulent genes.

Objective To understand the phenotypic characteristics of foodbome Vibrio parahaemolyticus in Guangdong province through carrying out a comprehensive comparison including pulse field gel electrophoresis,ribotyping and serotyping.Methods 74 different Vibrio parahaemolyticus strains isolated from seafood and cases due to food poisoning in Guangdong province were under serotyping and susceptibility testing,in addition to the testing of direct heat hemolysin(tdh)and the heat hemolysin-related hemolysin hormone(trh)via PCR.Ribosomal genotyping(ribotyping)with EcoR Ⅰ restriction enzyme was utilized on 74 different Vibrio parahaemolyticus isolates,whereas pulsed-field gel electrophoresis(PFGE)with the Not Ⅰ restriction enzyme was used on 74 different Vibrio parahaemolyticus isolates.BioNumerics software was used to compare the isolates from different sources,times and places in order to elicit the correlation between different strains.Results Although Vibrio parahaemolyticus was 100.00％ sensitive to chloramphenicol,it still presented different levels of resistance against 13 other antibiotics.Among the 74 different strains of Vibrio parahaemolyticus under testing,24.32％ showed positive for the tdh virulence gene,whereas 4.05％ positive for trh.74 different Vibrio parahaemolyticus strains were found to belong to 26 serotypes,where the O5:K17 and O2:K28 serotypes were dominant in those isolates that causing seafood-poisoning.The O3:K6 serotype was found to be the dominant of those isolates that causing food-poisoning.Based on ribosomal genotyping,the 74 Vibrio parahaemolyticus isolates were divided into 62 different ribotypes,whereas the 74 strains of Vibrio parahaemolyticus were divided into 67 different PFGE types,thus exhibiting considerable genetic diversities of the strains.Conclusion Majority of the isolates causing food-poisoning carried tdh virulence gene.PFGE was shown to have the highest resolution,followed by ribotyping with serotyping being the lowest,where the combination of the three could improve the resolution.
