Objective To investigate the difference of clinical characteristics and outcomes between different isoforms of BCR/ABL in adults with Philadelphia-positive acute lymphoblastic leukemia (ALL).Methods The data of 106 adults with Ph+ALL diagnosed in our hospital from January 1, 1996 to December 31, 2007 were reviewed. The difference of clinical characteristics between different subgroups of BCR/ABL was compared and their relation with outcomes was studied. Results The median age of the 106 patients was 34 years and the median white blood cell count at baseline was 28. 5 × 109/L. Comparative analysis demonstrated that patients in p210 group had an older age, higher blood platelet count (BPC) and more frequent occurrence of splenomegaly. Referring to the outcomes, the complete remission (CR) rate of the two groups were 92. 2% and 93.9%, respectively. The median overall survival (OS) and relapse free survival (RFS) in p190 group were 13 months and 10 months, the 1,3-year estimated OS were (54. 7±6. 7)% and (5.5±5.2)%, and the 1,3-year estimated RFS were (40. 2±6. 8)% and (7. 8±6. 7)%,while in p210 group, the median OS and RFS were 15 months and 10 months, respectively, the 1,3-year estimated OS were (65.8±8. 9)% and (14. 5±7.4)%, and the 1,3-year estimated RFS were (48. 3±9. 4)% and (12. 9±7. 7)%. All of the above data had no statistic significance between the two groups.Conclusion Majority of the adults with Ph+ALL is p190 positive and patients with p210 have older age, higher BPC and more frequent occurrence of splenomegaly, while there is no significant difference between p190 group and p210 group in CR rate, RFS and OS.

OBJECTIVE:
This study was designed to find out the impact of micro-ecological environment on the incidence of allergic rhinitis after developing a model of allergic rhinitis on mice.
METHOD:
Sixty mice were randomly divided into GF group (n=30) and SPF group (n=30). Mice of GF group were fed in the germ-free environment and mice of SPF group were fed in the specific pathogen-free environment. Then each group were randomly divided into model group (20 mice) and control group (10 mice). Establish allergic rhinitis model in the mice of model group using ovalbumin (OVA) at the age of 6 weeks, observe and score the corresponding symptoms and signs that could been induced. Stain with hematoxylin eosin (HE) staining method for nasal mucosa to observe the morphological changes. Using enzyme linked immunosorbent assay to detect the concentration of IgE, IFN-γ and IL-4 in the peripheral blood serum.
RESULT:
The chi square test showed that the incidence of allergic rhinithis in the mice of GF group was significantly higher than that in the SPF group (P< 0. 05). HE staining showed that the nasal mucosas of allergic rhinitis positive reaction mice were highly congestive and edematous and had a large number of inflammatory cell infiltration, while there was no abnormal morphology of nasal mucosas in mice with no allergic rhinitis reaction. EOS counting displayed that the number of eosinophilic cells in nasal mucosa of positive allergic rhinitis reaction mice was increased significantly. The concentration of IgE and IL-4 in the serum of positive allergic rhinitis reaction mice was highly increased (P <0. 05), and IFN-γ was significantly decreased (P< 0.05).
CONCLUSION
The difference of micro-ecological environment may play a key role in the occurrence of allergic rhinitis in mice.

OBJECTIVETo analyze the characteristics of cytogenetic aberration of adults with Philadelphia chromosome-positive (Ph+) and/or bcr-abl positive (bcr-abl+) acute lymphoblastic leukaemia (ALL), and investigate its influence on patients' outcomes.
METHODRetrospective analysis of 100 adult Ph+ ALL patients from January 1, 1996 to December 31, 2007 was carried out. The type, distribution and frequency of chromosome aberration were summarized, and compared among different subgroups.
RESULTS1) In all cases, 72 had chromosome aberrations, including 22 with sole Ph chromosome, 44 Ph+ with additional abnormalities, which included double Ph, monosomy 7, monosomy 20, trisomy 8 trisomy 21, 9p deletion and 22 deletion. 2) Patients with pseudodiploid and hyperdiploid had higher WBC count, and inferior outcome with lower rates of overall survival (OS) and relapse free survival (RFS). 3) Ph+ group also had higher WBC counts and inferior outcome with low OS and RFS rates. There was no statistic significance between sole Ph+ group and Ph plus additional aberrations group. 4) Patients with both abnormal and normal metaphase (AN) and with solely abnormal metaphase (AA) had higher WBC count, less frequent P190 occurrence and inferior outcome than those only normal metaphase (NN) group, whereas, there was no difference between AA and AN groups. 5) Double Ph chromosome had a lower frequency of P190 and inferior OS than non-double Ph group.
CONCLUSIONAdults with Ph+ ALL have complicated cytogenetic abnormalities, pseudodiploid and hyperdiploid indicate inferior outcome, and double Ph chromosome may be a unfavorable prognostic factor.

Objective To observe the relationship of IL-17 and arterial blood gas, fibrin fragment D (D-D) in patients with both pulmonary embolism (PE) and obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods We collected 20 patients with both PE and OSAHS and 43 patients with only PE who hospitalized in the first ward of pneumology department of the Second Affiliated Hospital of Kunming Medical University, then measured D-D, IL-17 in venous blood and arterial blood gas and recorded them to analysis.Re s ults PO2 in patients with both PE and OSAHS was significantly lower than that in patients with only PE, while D-D and IL-17 of the latter were markedly lesser than the former. Conclus ions The expression of IL-17 between the 2 groups of patients has statistically significant difference. What's more, the expression of IL-17 is positively associated with hypercoagulability and Body Mass Index (BMI), and the result shows a negative relation between arterial blood oxygen partial pressure and IL-17, suggesting that IL-17 may be relate to the common progress of PE and OSASH. Thus, IL-17 can be used in the detection of patients with both PE and OSASH

PURPOSE: Numerous previous studies have reported inconsistent results about the differences between synchronous contralateral breast cancer (sCBC) and metachronous contralateral breast cancer (mCBC). This study aimed to compare the clinical characteristics and outcomes between sCBC and mCBC and determine predictive factors for the survival of sCBC and mCBC patients. METHODS: Using the Surveillance, Epidemiology, and End Results Program database, we identified sCBC or mCBC patients from 2000 to 2010. The Kaplan-Meier method and Cox proportional hazards regression analysis were used to analyze overall survival and breast cancer-specific survival (BCSS) rates of sCBCs and mCBCs, respectively. RESULTS: Overall, 14,057 sCBC (n = 8,139, 57.9%) and mCBC (n = 5,918, 42.1%) patients were included. The first tumors of sCBC were more likely to have higher stage and more lymph and distant metastases, whereas those of mCBC were more often infiltrating ductal carcinoma (IDC), had localized stage, were estrogen receptor (ER) and progesterone receptor (PR) negative, and had less axillary nodal involvement. The second tumors of mCBC tended to be IDC and have higher grade, adverse stage, ER and PR-negativity; and more axillary nodal involvement, compared to the second tumors of sCBC. mCBC patients had significantly favorable 5-year BCSS but worse long-term BCSS compared with sCBC patients. Moreover, subgroup analysis revealed no significant difference of BCSS between sCBC and mCBC among patients aged 18–60 years. Multivariate analysis indicated that age, grade, and stage of 2 tumors; surgery for second tumor; and ER status of the second tumor were independent prognostic factors for BCSS of contralateral breast cancer (CBC). CONCLUSION: The characteristics and outcomes of sCBCs and mCBCs were substantially different. sCBC and mCBC patients may have different prognosis, and the prognosis of CBC depends on the first and second tumors.

Objective: To investigate the spectrum of gene mutations in adult patients with B-acute lymphoblastic leukemia (B-ALL), and to analyze the influences of different gene mutations on prognosis. Methods: DNA samples from 113 adult B-ALL patients who administered from June 2009 to September 2015 were collected. Target-specific next generation sequencing (NGS) approach was used to analyze the mutations of 112 genes (focused on the specific mutational hotspots) and all putative mutations were compared against multiple databases to calculate the frequency spectrum. The impact of gene mutation on the patients' overall survival (OS) and recurrence free survival (RFS) was analyzed by the putative mutations through Kaplan-Meier, and Cox regression methods. Results: Of the 113 patients, 103 (92.0%) harbored at least one mutation and 29 (25.6%) harbored more than 3 genes mutation. The five most frequently mutated genes in B-ALL are SF1, FAT1, MPL, PTPN11 and NRAS. Gene mutations are different between Ph+ B-ALL and Ph- B-ALL patients. Ph- B-ALL patients with JAK-STAT signal pathway related gene mutation, such as JAK1/JAK2 mutation showed a poor prognosis compared to the patients without mutation (OS: P=0.011, 0.001; RFS: P=0.014,<0.001). Patients with PTPN11 mutation showed better survival than those without mutation, but the difference was not statistically significant (P value > 0.05). Besides, in Ph+ B-ALL patients whose epigenetic modifications related signaling pathway genes were affected, they had a worse prognosis (OS: P=0.038; RFS: P=0.047). Conclusion: Gene mutations are common in adult ALL patients, a variety of signaling pathways are involved. The frequency and spectrum are varied in different types of B-ALL. JAK family gene mutation usually indicates poor prognosis. The co-occurrence of somatic mutations in adult B-ALL patients indicate the genetic complex and instability of adult B-ALL patients.

OBJECTIVE:
To observe the effects of auricular thumbtack needle on breast feeding and lactation function in primiparous women with cesarean section, and to explore its mechanism of action from the perspective of lactation-related gene expression.
METHODS:
One hundred cases of primiparous women with cesarean section were randomly divided into an observation group (50 cases, 3 cases dropped off) and a control group (50 cases, 2 cases were eliminated). The patients in the control group were treated with routine obstetric care. Based on the treatment of the control group, the patients in the observation group were treated with auricular thumbtack needle at Neifenmi (CO18), Xiong (AH10), Xiongzhui (AH11), Shenmen (TF4), and Jiaogan (AH6a), etc., with one side of auricular point selected, only once for a total of 3 d. The lactation initiation time, lactation adequacy rate at postpartum 72 h, exclusive breastfeeding rate at postpartum 42 d, and breastfeeding score after treatment were compared between the two groups. Real-time quantitative PCR and Western blot method were used to detect the mRNA and protein expression levels of TDP-43, Btn1A1 and XDH.
RESULTS:
After treatment, the lactation initiation time in the observation group was earlier than that in the control group (P<0.01), and breastfeeding score in the observation group was higher than that in the control group (P<0.01). The lactation adequacy rate at postpartum 72 h was 63.8% (30/47) in the observation group, which was higher than 41.7% (20/48) in the control group (P<0.05). The exclusive breastfeeding rate at postpartum 42 d was 72.3% (34/47) in the observation group, which was higher than 47.9% (23/48) in the control group (P<0.05). The mRNA and protein expression levels of TDP-43 and Btn1A1 in breast milk in the observation group were higher than those in the control group (P<0.01), while there was no statistically significant difference in mRNA and protein expression of XDH in breast milk between the two groups (P>0.05).
CONCLUSION
The auricular thumbtack needle in addition to routine care could promote lactation initiation, improve lactation adequacy rate and exclusive breastfeeding rate in primiparous women with cesarean section, and the action mechanism may be related to up-regulation of TDP-43 and Btn1A1 expression.

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.
