Objective To compare the obesity-related laboratory results between single abdominal obesity and symmetric obesity in adolescents. Methods A total of 11 460 young students in two provinces were surveyed.Among them 31 students with symmetric obesity (SO group) and 39 students with single abdominal obesity (SAOgroup) were enrolled into the analysis. The age, gender, and body weight were matched between two groups.Blood pressure (Bp), lipids, leptin (LP), fasting plasma glucose (FPG), fasting insulin (FINS), insulin sensi-tivity index (ISI), and serum uric acid (UA) were measured. Liver ultrasonic imaging was performed. The differ-ences of the laboratory results were compared. Results Compared with the SO group, in the SAO group, the inci- dence of fatty liver ( P = 0. 04 ), triglyceride ( P < 0. 001 ), apelipoprotein B ( P < 0. 005 ) as well as FINS, LP,and UA (all P <0. 001 ) were significantly higher, while apolipoprotein A was significantly lower (P <0. 005). LP were positively correlated with FINS (P <0. 001 ) and negatively correlated with ISI (P <0. 001 ). FINS were posi-tively correlated with UA ( P < 0. 001 ) and negatively with ISI ( P < 0. O01 ). Conclusion Adolescents with ab-dominal obesity have higher risks of endocrine and cardiovascular diseases than those with ymmetrical obesity.

Objective To investigate the regulatory effects of miR-145 on the proliferation,cell cycle and apoptosis of a human keratinocyte cell line HaCaT.Methods miR-145 mimics and negative control (NC) mimics were chemically synthesized and then transiently transfected into HaCaT cells respectively.After additional culture for different durations,real-time PCR was performed to determine the expression level of miR-145,MTS assay to estimate cell proliferation,and flow cytometry to detect cell apoptosis and cycle.Luciferase assay,real-time PCR and Western blot were conducted to determine whether NRAS was the target gene of miR-145.Results The miR-145 expression level in miR-145 mimic-transfected cells increased by 85.00 ± 1.21 folds compared with NC mimic-transfected cells (t =115.90,P ＜ 0.0001).The transfection with miR-145 mimics significantly inhibited the proliferation of HaCaT cells (F =8.76,P =0.008),and the inhibitory effect significantly varied with the duration (24-96 hours) of culture after transfection,with no interaction effect between the transfection with miR-145 mimics and culture duation (F =1.21,P =0.18).Compared with NC mimic-transfected cells,those transfected with miR-145 mimics showed a significant increase in the proportion of early apoptotic cells (18.9％ ± 4.1％ vs.4.3％ ± 1.2％,t =7.126,P ＜ 0.01),late apoptotic cells (9.3％ ± 2.3％ vs.3.6％ ± 1.6％,t =12.38,P ＜ 0.01),G1-phase cells (85.83％ ± 5.2％ vs.62.08％ ± 6.23％,t =11.78,P =0.007),but a significant decrease in the percentage of G2-phase cells (6.26％ ± 1.2％ vs.19.36％ ± 3.45％,t =7.610,P =0.017) and S-phase cells (7.91％ ± 1.3％ vs.18.56％ ± 5.23％,t =7.230,P=0.019).As luciferase assay showed,luciferase activity was significantly lower in HaCaT cells cotransfected with miR-145 mimics and a recombinant luciferase reporter vector psi-CHECK2-NRAS-wild carrying the wild-type 3'UTR of NRAS than in those cotransfected with NC mimics and the vector psi-CHECK2-NRAS-wild (t =11.09,P =0.008),but similar between cells cotransfected with miR-145 mimics and a recombinant luciferase reporter vector psi-CHECK2-NRAS-mut carrying the mutant-type 3'UTR of NRAS and those cotransfected with NC mimics and the vector psi-CHECK2-NRAS-mut (P ＞ 0.05).Real-time PCR and Western blot revealed that the overexpression of miR-145 mimics had no significant effect on NRAS mRNA expression (P ＞ 0.05),but significantly inhibited NRAS protein expression (1.52 ± 0.07 vs.0.20 ± 0.02,t =28.43,P＜ 0.01).Conclusion miR-145 might inhibit proliferation and promote apoptosis of HaCaT cells by influencing cell cycle via NRAS.

Objective To study the relationship between viral infection and chronic obstructive pulmonary disease (COPD),and the effect of viral infections on the changes of Th1/Th2 in COPD patients. Methods The se-ra from 81 patients with acute exacerbations of COPD,25 patients with stable COPD and 22 healthy subjects were tested for specific IgM of respiratary syncytial virus(RSV) ,herpes simplex virus type 1 (HSV-1), parainfluenza vi-rus (PIV), adenovirus (ADV) and cytomegalovirus (CMV) by indirect enzyme-linked immunosorbent assay (ELISA). Supernatant INF-γ and IL-4 cultured with PHA were determined. Results The positive rates of IgM in patients with acute exacerbations of COPD compared with those in patients with stable COPD and healthy subjects were significantly different(P <0.001 ). The level of INF-γ, and IL-4 in patients with acute exacerbations of COPD and stable COPD compared with normal control group;the level of INF-γ (242±43) and the of IL-4(42±9) in pa-tients with acute exacerbations of COPD was not significantly different as compared with the level of INF-γ( 198±32) and the level of IL-4(56±11 ) in patients with stable COPD (P<0.05), but the level of INF-γ was increased (90±18)and IL-4 was decreased (141±24) in control group (P<0.05). Compared with those in IgM negative group, the levels of INF-γ were significantly higher and the levels of IL-4 were significantly lowerIL-4 in lgM positive group( P<0.01 ). Conclusion Virus infection is a rather important factor in acute exacerbations of COPD, and COPD is characterized by a predominance of Th1-type response,and there is more significant Th1 response predomi-nance in COPD with virus infection.

Objective To investigate iodine nutrition status in healthy adults in Xinjiang Urumqi city and their relationship to ethnicity, gender and age. Method A cross-sectional survey was performed in 2 100 residents of Xinjiang Urumqi 2 communities in May 2013, of which 1 835 healthy adults aged 18-84 years, mean age 46.3 ± 14.2 years were enrolled. Urine iodine with arsenic-cerium catalytic spectrophotometry and salt iodine and water iodine of the residents were measured. Result The water iodine content was 3.14 μg/L, salt iodine was 27.75 mg/kg, 1 835 urine samples were collected, the urinary iodine median(MUI) was133.4 μg/L, iodine deficiency accounted for 32.37% (595 cases), iodine sufficient 42.94% (788 cases), iodine super-sufficient 14.44%(265 cases), iodine excess 10.19%(187 cases). The urine iodine level in Han ethnic group was higher than those in Uygur adults, no significant difference was observed between men and women (P>0.05). Urinary iodine levels among different age groups had no statistical difference, but in the older groups the level was lower than that in young or middle age adults. The urinary iodine level decreased gradually with the age increasing. Conclusion There was a sufficient pattern of iodine nutrition levels in healthy adults in Xinjiang Urumqi; there was a correlation between the level of iodine nutrition and the ethnicity but not with gender;iodine nutrition level in older age group was lower than those in younger age groups. Monitoring the urinary iodine continually and decreasing iodine intake may be necessary for part of iodine excess population.

Objective:To analysis the effect of health-promoting lifestyle and patient activation on self-management among tumor patients with PICC of the intermission of chemotherapy, so as to provide a basis for the targeted caring intervention programs.Methods:Using cross-sectional survey methods, from January 2021 to December 2022, the tumor patients with PICC of the intermission of chemotherapy of Tianjin Third Central Hosptial were investigated, using the General Demographic Questionnaire, Cancer Patients PICC Self-management Scale, Health Promotion Lifestyle Profile Ⅱ and Patient Activation Measure. Pearson correlation analysis and multiple linear stepwise regression analysis were used to analyze the data, and the structural equation model between related factors were established.Results:A total of 251 patients were collected in the this study, the scores of self-management were (153.12 ± 20.33) points, health-promoting lifestyle were (98.58 ± 16.05) points, and patient activation were (50.52 ± 6.51) points. The dimensions scores and total scores of self-management were positively correlated with the health-promoting lifestyle and patient activation in tumor patients with PICC ( r values were 0.503-0.910, all P<0.01). Multiple linear regression analysis showed that the health-promoting lifestyle and the patient activation were the influencing factors of the patient's self-management ability ( t=2.67, 1365, both P<0.05). Pathway analysis results showed that patient activation played a partially mediating role between health-promoting lifestyle and self-management, the effect value was 0.33 (95% CI 0.301-0.557), accounting for 46.5% of the total effect. Conclusions:Health-promoting lifestyle and the patient activation were the influencing factors of the self-management ability of tumor patients with PICC, patient activation played a partially mediating role between health-promoting lifestyle and self-management.

Objective To establish a reference range for specific thyroid function during pregnancy and to explore the influencing factors of hypothyroxinemia during pregnancy.Methods A retrospective analysis of 2 996 cases of thyroid function in the pregnant women who were with single pregnancy and without thyroid diseases and family history of those diseases.Results (1) Establish a unified reference range for specific thyroid function during pregnancy;the early,middle,and late trimesters thyrotropin (TSH) ranges were 0.02-6.39,0.16-6.23,0.64-6.59 mU/L,respectively,while free thyroxine (FT4) ranges were 11.32-23.00,9.39-18.92,8.54-16.73 pmol/L respectively.The specific reference ranges of Han and Uygur pregnant women were established separately.There was no difference in the detection rates of various thyroid diseases when using their respective reference ranges and the unified reference range of the hospital (P ＞ 0.05).(2) The detection rate of various thyroid diseases (except subclinical hyperthyroidism) of our subjects with China guideline reference range was significantly higher than the reference range with the hospital (P＜0.05).(3) The detection rates of hypothyroxinemia in all pregnant women with FT4 cut points of P2.5 and P5 were 4.3％ and 7.4％,respectively,of which the Han population was 4.3％ and 7.1％,respectively,and the Uygur population was 4.3％ and 7.9％,respectively.(4) Comparing the mean age,gestational age,median urine iodine,and thyroid antibody positive rate between the hypothyroxinemia group and the control group,only the mean age and gestational age were different (P＜0.05);Logistic binary regression analysis showed that age was the risk factor for hypothyroxinemia during pregnancy (OR =1.035,95％ CI 1.006-1.066,P ＜ 0.05).Conclusions The Han and Uygur pregnant women in this area both can use the thyroid reference range of our hospital during pregnancy.The establishment of thyroid reference range may avoid over-diagnosis of thyroid disease during pregnancy.Age is a possible influencing factor of hypothyroxinemia during pregnancy.

Objective To investigate clinical and hematological features of myeloid neoplasms with eosinophilia and abnormal PDGFRA/B and the effect of imatinib. Methods The data of three eosinophilia patients with abnormal PDGFRA/B fusion gene in Changhai Hospital, the Second Military Medical University and 22 Chinese cases reported in Chinese medical journals were analyzed. Thirty-one cases of idiopathic hypereosinophilic syndrome from Changhai Hospital, the Second Military Medical University were used as the controls. Results Compared with idiopathic hypereosinophilic syndrome, no differences were found in age, percentage of bone marrow eosinophils and counts of platelets in peripheral blood in myeloid neoplasms with eosinophilia and abnormal PDGFRA/B (all P ＞0.05), but statistical differences were found in gender (χ2＝5.080, P ＝ 0.016), peripheral blood white blood cell count (t ＝ 4.908, P ＝ 0.001), eosinophilic granulocyte absolute value (χ2＝ 17.230, P ＝ 0.001) and hemoglobin concentration (t ＝ 2.770, P ＝ 0.013). The median follow-up time was 17 months (3-108 months) in 24 myeloid neoplasms patients with eosinophilia and abnormal PDGFRA/B from Chinese report. Complete hematopoietic remission (CHR) rate was 91.7 % (22/24) after the treatment of imatinib. The total complete molecular remission (CMR) rate was 75.0 % (18/24). The median time of remission was 3 months (1-8 months). CMR in patients with PDGFRA and with PDGFRB was 76.5 % (13/17) and 85.7 % (6/7), respectively. Only one patient (4.2 %) died of disease relapse. Conclusion Imatinib has a favorable effect on myeloid neoplasms with eosinophilia and abnormal PDGFRA/B featured by distinct hematologic and clinical manifestations.

OBJECTIVETo investigate the efficacy and safety of precise laparoscopic Roux-en-Y gastric bypass(LRYGB) in the treatment of obesity and metabolic diseases.

METHODSClinical and follow-up data of obese patients underwent precise LRYGB in our department between June 2011 and April 2013 were analyzed retrospectively.

RESULTSA total of 140 obese patients were included in this study. All the precise LRYGB procedures were successfully performed with no conversion to open surgery or perioperative death. Average operation time was (138.0±21.3) min, postoperative hospital stay was (5.2±1.2) d. No severe complications was observed. The percentages of excess weight loss in 1, 3, 6, and 12 month after operation were (26.4±8.6)%, (53.3±6.7)%, (75.3±7.9)%, (78.5±8.5)%, respectively. The improvement rates of fatty liver, hyperlipidemia, hypertension and type 2 diabetes mellitus were 84.6%(33/39), 92.3%(12/13), 77.3%(17/22) and 82.4%(14/17).

CONCLUSIONSPrecise LRYGB is a modified and optimized traditional surgical technique which does not significantly increase the operative time. It is safe and feasible. The postoperative weight loss effect is significant and it can effectively improve the related co-morbidities.
