Chromosomal aberrations detection in chronic lymphocytic leukemia by conventional cytogenetics using DSP30 and IL-2 / 中华血液学杂志

Objective@#To study the value of unmethylated cytosine guanine dinucleotide oligodeoxynucleotide (DSP30) and IL-2 in the conventional cytogenetic (CA) detection of the chromosomal aberrations in chronic lymphocytic leukemia (CLL) .@*Methods@#Bone marrow or peripheral blood cells of CLL patients were cultured with DSP30 plus IL-2 for 72 h, following which R-banding analysis was conducted. Fluorescence in situ hybridization (FISH) was performed in 85 patients. CA results were compared with data obtained by FISH.@*Results@#Among 89 CLL patients, the success rate of chromosome analysis was 94.38% (84/89) . Clonal aberrations were detected in 51 patients (51/84, 60.71%) . Of them, 27 (27/51, 52.94%) were complex karyotype. Among 85 CLL patients tested by FISH, chromosomal abnormalities were detected in 74 (74/85, 87.06%) patients, of which 2 (2/74) patients were complex karyotypes, accounting for 2.70%. Of the 85 CLL patients examined by FISH, 50 had abnormal karyotype analysis, 30 had normal karyotype, 5 failed to have chromosome analysis. Among them, 25 cases showed clonal aberrations by FISH assay but normal by CA, and 4 cases were normal by FISH but displayed aberrations in chromosome analysis, and totally 78 (91.76%) cases with abnormality detected by the combination of the two methods. The frequency of 13q- abnormality detected by FISH was significantly higher than that by CA analysis (69.41%vs 16.67%, P<0.001) , while the frequency of 11q-,+12 and 17p- detected by two methods showed no significant difference (P>0.05) . The detection rate of complex abnormalities in conventional karyotype analysis was higher than that in FISH (50.98%vs 2.70%) . In addition, 11 low-risk and 9 intermediate-risk patients according to FISH results showed complex karyotype by cytogenetics, and were classified into high-risk cytogenetic subgroup.@*Conclusion@#DSP30 and IL-2 are effective in improving the detection rate of CA in CLL patients (60.71%) and CA is more effective to detect complex karyotype. However, FISH had a higher overall abnormality detection rate (87.06%) than CA, especially for 13q-. The combination of CA and FISH not only enhanced the detection rate of clonal aberrations to 91.76%, but also provided more precise prognosis stratification for CLL patients, thus to provide more information for clinical implication.

MN1-ETV6 and ETV6-MN1 fusion genes were detected respectively in 4 and 3 patients.@*CONCLUSION@#t(12;22)(p13;q12) is a rare but recurrent chromosomal abnormality in myeloid leukemia, and is related to poor prognosis. allo-SCT is valuable for patients with t(12;22)(p13;q12).

Report of breast cancer incidence and mortality in China registry regions, 2008-2012 / 中华肿瘤杂志

Objective@#The registration data of local cancer registries from 2008 to 2012 were collected by National Central Cancer Registry to estimate the incidence and mortality of female breast cancer in China.@*Methods@#Data from 135 registries were qualified and selected in the final analysis, and each registry at least has submitted data from 2010 to 2012. Cancer incidence and mortality analyses were stratified by area (urban/rural, eastern/middle/western areas) and age group. The age composition of standard population of Chinese census in 2000 and Segi′s population were used for age-standardized incidence and mortality in China and worldwide, respectively.@*Results@#A total of 135 registries were recruited in the analysis, covering 629 333 910 person-years (382 669 450 in urban and 246 664 460 in rural). About 13, 258 cases of female breast cancer were diagnosed and 32 205 cases were dead between 2008 and 2012. Female breast cancer incidence was 42.67/100, 000 and age-standardized rate calculated by worldwide standard population was 28.87/100, 000. The crude incidence of urban area was 51.85/100, 000, higher than 28.29/100, 000 of rural area, and the crude incidence of eastern area was 46.35/100, 000, higher than 36.38/100, 000 of middle area and 27.60/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age 55-59 (96.36/100, 000), and declined at age 60. The age-standardized incidence rate by Chinese standard population increased 30.56% from 2003 to 2012. The increase rate of rural area was 72.32%, faster than 23.48% of urban area. Female breast cancer mortality was 10.36/100, 000 and the age-standardized rate calculated by worldwide standard population was 6.61/100, 000. The crude mortality of urban area was 11.64/100, 000, higher than 8.36/100, 000 of rural area, and the crude mortality of eastern area was 10.81/100, 000, higher than 7.38/100, 000 of middle area and 9.90/100, 000 of western area. The age-specific incidence increased with age and reached the peak at age above 85 (61.25/100, 000). Age-standardized incidence rate by Chinese standard population remained stable during the period of 2003-2012 (6.23%). The mortality rate mainly increased in rural area (54.94%), while decreased 2.32% in urban area over the 10 years.@*Conclusions@#Although the incidence and mortality of breast cancer in China are comparatively low worldwide, in China the incidence and mortality of female breast cancer have rose to the first and sixth place respectively among all the female cancers. The disease burden of breast cancer is very different between urban and rural area. Therefore, the targeted measure and strategy of control and prevention according to the area difference are needed.

Study on the Specificity of Meridian Points Via the Effect of Acupuncture at the Primary Points of the Three Yin Meridians of the Foot on Blood Pressure in an Animal Model of High/low Blood Pressure / 上海针灸杂志

Objective To investigate the effect of acupuncture at the primary points of the three yin meridians of the foot on blood pressure in an animal model of high/low blood pressure and explore the specific effect of the meridian points-the primary points of the three yin meridians of the foot.Methods The study included the parts of hypertension and hypotenstion. Both parts were allocated to the primary points of the three yin meridians of the foot, non-acupoint, model and blank groups, six rats each. Except the model and blank groups, all the groups were given acupuncture treatment for seven consecutive days. Blood pressure was measured after the completion of treatment. Five consecutive measurements were made in each rat. Mean values of blood pressure were taken.Results For the part of hypertension, blood pressure at each time point was higher in the acupuncture groups than in the blank control group and lower than in the model group, and there were statistically significant differences (P0.05). The hypotensive effect of Taibai was equal to that of the non-acupoint (P>0.05). For the part of hypotension, blood pressure at each time point was lower in the acupuncture groups than in the blank control group and higher than in the model group, and there were statistically significant differences (P<0.05), indicating that acupuncture at the primary points of the three yin meridians of the foot has a pressor effect. The pressor effect was worse in the the non-acupoint group than in the primary points of the three yin meridians of the foot group (P<0.05). The pressor effects of Taibai and Taixi were equal but worse than that of Taichong (P<0.05).Conclusions Acupuncture at the primary points of the three yin meridians of the foot has a specific bidirectional regulating effect on blood pressure. Of them, point Taichong produces a best bidirectional regulating effect on blood pressure.

Survival analysis of patients with lung cancer in Shanghai / 中国癌症杂志

Background and purpose: The incidence and mortality of lung cancer ranked first in China. This study aimed to describe lung cancer survival in Shanghai, and provide background information for cancer prevention and treatment evaluation. Methods: Data of lung cancer cases diagnosed during 2002-2006, follow-up information and death report were collected from Shanghai Cancer Registry. Life table method and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS) respectively. Related demographic characteristics and status were also analyzed to present the survival situations of the lung cancer survivors in Shanghai. Results: In this study, 41802 lung cancer cases were included in analysis. The 5-year OS and RS for lung cancer were 13.75% and 20.23% respectively, and median survival time was 318 days. Survival rate was higher among females than males, with the 5-year OS of 15.49% and 13.00% respectively. The 5-year OS was higher among suburban residents (14.25%) than urban residents (13.23%). Survival rates decreased with increasing age and advanced stage. Patients aged 0-34 had a 5-year OS of 38.21%, while patients aged above 75 had a 5-year OS of 5.48%. Patients diagnosed with stage Ⅰ had a 5-year OS of 55.47%, while patients diagnosed with stage Ⅳ had a 5-year OS of 5.27%. Survival of lung cancer patients differed by tumor histological subtype. The 5-year OS of squamous lung cancer (24.40%) was higher than other histological types, followed by adenocarcinoma (22.26%), large cell (20.27%) and small cell lung cancer (12.22%). From 1972-1976 to 2002-2006, the 5-year OS of urban male patients increased from 6.8% to 12.4%, and 5-year OS of urban female patients increased from 7.3% to 14.9%. Analysis of RS gave the similar results. Conclusion: During the past 30 years, survival rate of lung cancer patients in Shanghai improved steadily, and the survival condition is above average among different countries and areas. However, survival rate of lung cancer is still low compared with other types of cancer. Future focus should be placed on the control of tobacco smoking, early detection by low-dose helical computed tomography and targeted therapy to further improve lung cancer survival.

Prevalence and trend of gastrointestinal malignant tumors in the elderly over 75 years old in China / 中华胃肠外科杂志

Gastrointestinal malignant tumors are the most common malignant neoplasms among the elderly people over 75 years old in China. There are 122.1 thousand new gastric cases and 78.2 thousand new colorectal cancer cases diagnosed each year in China, which accounts for 42.73% and 18.08% respectively of the cases with same age in the world. The gastric cancer accounts for 25.13% and colorectal cancer accounts for 28.86%of all the malignancies in the elderly. The gastric cancer death accounts for 36.38% and colorectal cancer death accounts for 44.68% in those people over 75 years old in China. It was estimated that the risk of developing gastrointestinal malignant tumors of these elderly people was about 5-6 times and the risk of death of gastrointestinal malignant tumors was about 7-8 times of the general population. Compared with the general population and the people of 55-74 years old, the incidence of gastric cancer in the elderly decreased more slowly and the incidence of colorectal cancer increased more quickly over the past 40 years, which brought significant double burden. The survival rate of gastrointestinal malignant tumors in these elderly was lower than that of the general population. We summarized the incidence, mortality, survival and trend of gastrointestinal malignant tumors in the Chinese elderly, in order to provide data for predicting the age distribution and disease burden in the future, to improve the awareness for cancer prevention and control among these elderly, and to call attention to epidemiology, preclinical and clinical medicine for the elderly, especially in the field of study on the influence between comorbidity and cancer treatment, with the aim of improving survival and quality of life among the elderly.

However the frequency of Th17 cells,serum levels of IL?6,IL?17,IL?23 in severe HFMD groups were significantly increased( F=646. 81,5. 904,10. 557,3. 490 respectively;P<0. 05) . Conclusion The changes of Treg and Thl7 cells and related cytokines appear in peripheral blood of patients with HFMD in the initial stage of infection caused by Enterovirus 71 virus. The frequency of Treg cell is decreased,however,the frequency of Thl7 cells frequency is increased,as a result,which may spread inflammato?ry reaction and cause complication.

Effects of electroacupuncture at points selected by orthogonal experiment on the extracellular signal regulated kinase signal pathway in a rat model of cerebral ischenia-reperfusion injury / 中国组织工程研究

BACKGROUND:Acupuncture point matching is little reported in the electroacupuncture for cerebral ischemia-reperfusion injury. OBJECTIVE:To explore the influence of electroacupuncture acupoints selected by orthogonal experiment on rats with cerebral ischemia reperfusion and extracel ular signal regulated kinase (ERK) signal pathway. METHODS:150 Sprague-Dawley rats were randomly divided into five groups:sham operation group rats were exposed the middle cerebral artery only;models of cerebral ischemia reperfusion were established in the rats in model and orthogonal groups. Then rats in the orthogonal groups 1 (Baihui (DU 20), Quchi (LI 11), Zusanli (ST 36), and Chize (LU 5)), 2 (Baihui (DU 20), Zusanli (ST 36), Chize (LU 5), and Sanyinjiao (SP 6)) and 3 (Hegu (LI 4), Zusanli (ST 36), Chize (LU 5) and Sanyinjiao (SP 6)) were given electroacupuncture at acupoints selected by orthogonal experiment, respectively. RESULTS AND CONCLUSION:Compared with the model group, in al orthogonal groups, the neurological function deficit scores were decreased, infarct volume was smal er, the number of microvessel density in the ischemia region and the p-ERK expression level in the cortex and hippocampal CA1 region of ischemic hemisphere were increased, and significant changes were found in the orthogonal group 3. These findings indicate that electroacupuncture at points of Hegu (LI 4), Zusanli (ST 36), Chize (LU 5) and Sanyinjiao (SP 6) selected by orthogonal experiment can significantly reduce the infarct volume of cerebral ischemia-reperfusion injury in rats possibly by regulating the ERK signaling pathway.

Survival analysis of liver cancer between 2002 and 2006 in Shanghai / 中国癌症杂志

Background and purpose:China is a high incidence area of liver cancer. The latest monitoring data in Shanghai show that liver cancer is one of the most common cancers with very high disease burden. This study aimed to describe and analyze the population-based survival rates of patients with liver cancer in Shanghai.Methods:Data of liver cancer cases diagnosed between 2002 and 2006, including follow-up information and death report, were collected from Shanghai Cancer Registry. Life table and Ederer Ⅱ were used to calculate observed survival (OS) and relative survival (RS). The related demographic characteristics and status were also analyzed to relfect the survival situations of the liver cancer survivors in major areas of Shanghai.Results:In this study, 20 702 liver cancer cases were included in analysis. Five-year OS rate for liver cancer was 11.72%, whereas RS rate was 15.45%. The OS of male liver cancer patients was higher than that of female patients. Patients whose age ranged from 0-34 years had the highest survival rates than patients from other age groups. The survival of patients with hepatocellular carcinoma was higher than that of patients with other histologic types of liver cancer. Signiifcant difference in survival had also been found among patients with various stages of liver cancer. The survival rate of patients with stageⅠliver cancer was much higher than that of patients with stageⅢ andⅣ liver cancers. There was no signiifcant difference in the survival of liver cancer patients between urban and rural residents. Over the past 3 decades, the 5-year OS increased dramatically in Shanghai. Conclusion:The survival of patients with liver cancer in Shanghai is improved signiifcantly. The prognosis is poor compared with other common malignant tumors. It is necessary to strengthen the risk factors and high-risk population control and intervention in the future.

Survival analysis of patients with gastric cancer in Shanghai / 中国癌症杂志

Background and purpose:Incidence and mortality of gastric cancer have increased gradually in China. Population-based cancer survival rate can relfect improvements in cancer diagnosis and treatment, as well as provide evidence for gastric cancer prevention and control.Methods:Data from gastric cancer incidence and follow-up between 2002 and 2006 were collected by the Shanghai Cancer Registry. Life table and EdererⅡ were used to calculate observed survival (OS) and relative survival (RS).Results:A total number of 28 243 gastric cancer cases were documented between 2002 and 2006 in Shanghai. The 5-year OS and RS of gastric cancer were 32.15% and 45.81%, respectively. Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type, but not by gender. Patients aged 35-44 years who were diagnosed at stageⅠ or with tubular adenocarcinoma, had the highest survival rates. Moreover, patients in rural areas had higher 5-year OS than those in urban areas. During the period 2002-2006,both 5-year OS and RS of gastric cancer increased dramatically, as compared with 1972-1976. Conclusion:Survival rates of gastric cancer varied by age, residence, diagnostic stage, and tumor histological type. The 5-year OS and RS signiifcantly increased in Shanghai over the past three decades, but are still far below developed countries. Early diagnosis of gastric cancer would be an effective strategy to improve survival and prognosis of patients with gastric cancer.

Methods The clinical data of 112 patients with HBV-related cirrhosis were studied retrospectively. The patients were divided into non-EV (NEV) group (30 cases) and EV group (82 cases) according to the results of gastroscopy. In EV group, there were mild varices in 21 cases (mild EV group), moderate varices in 47 cases (moderate EV group) and severe varices in 14 cases (severe EV group). The age, gender, platelets, glutamyl transpeptidase, prothrombin time, albumin, bilirubin, portal vein diameter, spleen vein diameter and thickness of spleen were compared, and the relationship was analyzed between each index and EV. Results There were no statistical differences in gender, age, albumin, bilirubin, prothrombin time and glutamyl transpeptidase between NEV group and EV group (P>0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in EV group were significantly higher than those in NEV group:(14.1 ± 3.1) mm vs. (10.6 ± 2.3) mm, (8.9 ± 2.1) mm vs. (7.6 ± 1.6) mm and (4.8 ± 0.9) mm vs. (3.8 ± 1.0) mm, the platelets in EV group was significantly lower than that in NEV group:(86.8 ± 20.2) × 109/L vs. (163.5 ± 18.1) × 109/L, and there were statistical differences (P<0.01 or<0.05). The portal vein diameter, spleen vein diameter and thickness of spleen in moderate EV group and severe EV group were significantly higher than those that in NEV group and mild EV group: (13.5 ± 2.1) and (14.8 ± 3.6) mm vs. (10.6 ± 2.3) and (11.2 ± 3.1) mm, (8.3 ± 2.1) and (9.1 ± 1.1) mm vs. (7.6 ± 1.6) and (8.1 ± 1.9) mm, (4.7 ± 1.1) and (4.9 ± 0.9) mm vs. (3.8 ± 1.0) and (4.1 ± 1.2) mm, the platelet levels were significantly lower than those in NEV group and mild EV group: (72.8 ± 11.6) × 109/L and (63.8 ± 15.6) × 109/L vs. (163.5 ± 18.1) × 109/L and (100.2 ± 10.3) × 109/L, and there were statistical differences (P<0.05). The area under curve of response operating characteristic for predicting the presence of moderate and severe EV with portal vein diameter and platelets were 0.719 and 0.735, and the cut off value were 14 mm and 69 × 109/L. Conclusions The portal vein diameter and platelets can predict the presence of moderate and severe EV in patients with HBV-related cirrhosis.

Long-term survival analysis of different breast cancer molecular subtypes: Shanghai Breast Cancer Survival Study / 中华外科杂志

<p><b>OBJECTIVES</b>To analyze the survival of breast cancer molecular subtypes and to examine the effect of therapy on the long-term prognosis of different subtypes.</p><p><b>METHODS</b>This study included 3 586 breast cancer patients with estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2) information in Shanghai Breast Cancer Survival Study, a population-based prospective cohort study established in 2002. Molecular subtypes, based on immunohistochemistry were categorized as follows: Luminal A, Luminal B, HER2, and triple-negative subtype. Characteristics and clinical data were collected through questionnaires and medical records at baseline survey and sequential follow-up surveys. Survival rates of different molecular subtypes were analyzed and compared with Log-rank tests. Multiple Cox regression models were used to evaluate the effect of therapy on long-term prognosis of different molecular subtypes.</p><p><b>RESULTS</b>Among the 3 586 cases, Luminal A, Luminal B, HER2 and triple-negative breast cancer subtypes accounted for 54.5%, 16.6%, 13.9%, and 14.9%, respectively. With a median follow-up of 10.3 years (ranging 0.6 to 12.8 years), the 10-year overall survival (OS) rates for the four subtypes were 82.7% (95% CI: 80.9% to 84.4%), 77.7% (95% CI: 74.1% to 80.8%), 76.3% (95% CI: 72.3% to 79.8%), and 74.8% (95% CI: 70.9% to 78.3%), respectively. The 10-year disease to free survival (DFS) rates were 79.0% (95% CI: 76.7% to 81.0%), 76.0% (95% CI: 71.9% to 79.5%), 73.6% (95% CI: 68.9% to 77.7%), and 74.5% (95% CI: 69.4% to 78.9%), respectively. Significant difference in survival among four subtypes was observed (Log-rank test, P<0.01). Multivariate Cox regression indicated that hormonal therapy can significantly reduce the long-term risk of total mortality and recurrence breast cancer specific mortality among Luminal A subtype patients. Adjuvant chemotherapy could improve the long-term prognosis of triple-negative breast cancer. No benefit from radiotherapy was observed for four subtypes of breast cancer in terms of long-term prognosis.</p><p><b>CONCLUSIONS</b>Molecular subtypes based on ER/PR/HER2 could provide important information to predict breast cancer prognosis. The hormonal status was an important basis for individualized therapy and precision medicine.</p>

8p11 myeloproliferative syndrome with CEP110-FGFR1 fusion in a patient / 中华医学遗传学杂志

OBJECTIVE To explore the clinical and laboratory features of a patient with 8p11 myeloproliferative syndrome (EMS) and CEP110-FGFR1 fusion. METHODS Combined bone marrow cytology, fluorescence in situ hybridization, fusion gene detection was used to analyze the patient. RESULTS Clinically, the patient had many features similar to those with chronic myelomonocytic leukemia, which included hyperleukocytosis, marked eosinophilia, monocytosis, myeloid hyperplasia and hyperplasia. Fluorescence in situ hybridization analysis for FGFR1 gene rearrangement was positive. Further study of the mRNA also confirmed an in-frame fusion between exon 38 of the CEP110 gene and exon 9 of FGFR1 gene. CONCLUSION EMS with CEP110-FGFR1 fusion is a very rare and distinct myeloproliferative neoplasm. FISH and molecular studies may improve its diagnosis.

Influence of Exterior-interior Meridian Acupoint Selection on Hippocampal Cell Apoptosis and Expression of c-jun N-terminal Kinase in Rats with Ischemia-reperfusion Injury / 广州中医药大学学报

Objective To observe the influence of exterior-interior meridian acupoint selection on hippocampal cell apoptosis and c-Jun N-terminal kinase ( JNK) in ischemia-reperfusion injury rats, and to explore the possible protective mechanism for ischemia-reperfusion injury. Methods One hundred and twenty SD rats were randomly divided into sham-operation group (SH), model group (I/R), electroacupuncture (EA) group and JNK inhibitor SP600125 ( SP) group. The ischemia-reperfusion model was established by occlusion of middle cerebral artery with intraluminal thread. EA group was given EA on acupoints of Zusanli ( ST 36) , Sanyinjiao ( SP 6) , Chize ( LU 5) , Hegu ( LI 4) , once a day, based on the method of exterior-interior meridian acupoint selection. We observed the neurological behavioral changes by Longa neurological function standard, detected the activation of phosphorylated JNK ( p-JNK) by immunohistochemical method and examined the hippocampal apoptotic index by TUNEL method. Results The neurologic impairment scores of EA group and SP group were lower than I/R group (P<0.05) . Apoptotic index of I/R group was higher than SH group (P<0.01) and that of EA group and SP group was lower than I/R group (P <0.05) . The level of p-JNK in I/R group was higher than SH group ( P <0.01) and that of EA group and SP group was lower than I/R group ( P <0.05). Conclusion Exterior-interior meridian acupoint selection therapy has certain effect on alleviating neurologic impairment and reducing apoptosis in ischemia- reperfusion injury rats, and the mechanism might be associated with the inhibition of the activation of JNK signaling pathway.

Colorectal cancer survival analysis in major areas in shanghai China / 中国癌症杂志

Background and purpose:The incidence and mortality of colorectal cancer increased gradually in China, cancer survival rate plays an important role in guiding cancer prevention and treatment.Methods:Data of colorectal cancer cases diagnosed during 2002-2006, follow-up information and death report were from Shanghai Cancer Registry, Life Table and EdererⅡ were used to calculate observed survival (OS) and relative survival (RS), the related demographic characteristics and status were also analyzed to relfect the survival situations of the colorectal cancer survivors in major areas in Shanghai.Results:In this study, 16 682 colon cancer cases and 11 906 rectum cancer cases were included in analysis, 5-year OS rates for colon cancer and rectum cancer were 48.84% and 51.65%, RS rates were 70.50% and 71.31%. Signiifcant difference in survival had been found among the various diagnostic stages, the survival rate in stageⅠ was much higher than those in stageⅢ and stageⅣ. The survival of colorectal cancer patients with different gender, age, tumor histological and residential areas were also found with differences, female was higher than male, age ranged from >44-54 years had the highest survival rates than other age groups. The survival of epithelial tumors was higher than other histologic types in colon cancer, and the survival of non-epithelial tumors was higher than other histologic types in rectum cancer. Over the past 3 decades, the 5-year OS increased dramatically in Shanghai. Conclusion:The level of survival of colorectal cancer in Shanghai is similar with it in developed counties. Colorectal cancer survival rate with different population characteristics may provide suggestions and evidence for further improvement of early screening, diagnosis and treatment.
