Objective To investigate the effect of fat-1 gene encoding n-3 fatty acid desaturase on the proliferation and apoptosis of colon cancer cell HT-29. Methods fat-1 gene was transfected into HT-29 cells by liposomal reagent. The expression of fat-1 gene was detected by fluorescent micrographs and RT-PCR. Gas chromatography, MTT and flow cytometry were used to examine the change in n-6/n-3 PUFAs ratio, proliferation, cell cycle and apoptosis, respectively. Results After transfection of fat-1 gene, n-6/n-3 PUFAs ratio decreased significantly. Apoptosis of HT-29 cells was induced and cell cycle was changed. Apoptosis mainly appeared in the synthesis phase. Conclusion fat-1 gene encoding n-3 fatty acid desaturase can significantly decrease n-6/n-3 ratio. Consequently, apoptosis was triggered and cell cycle was changed. Tranfection of fat-1 gene into HT-29 cells may be a new potential treatment for colon cancer.

Objective We investigated the value of endoscopic evacuation and craniotomy of the hypertensive in?tracerebral hemorrhage to determine which methods are more suitable for the patients. Methods One hundred twenty pa?tients with hypertensive intracerebral hemorrhage participated this study. They were divided into classic surgical evalua?tion group (n=60) and endoscopic surgical evaluation group (n=60) according to their corresponding surgery strategies. Each patient was assessed by the preoperative Glasgow Coma Scale (GCS), the mean rate and time of hematoma evacua?tion from onset to operation, the postoperative GCS, the mean time of admission in neuro-intensive care unit (NICU) and Glasgow Outcome Score (GOS) at 3 month after surgery. Results The continuous (≥3 months) follow-up surveys were all completed by 120 patients. There was no statistical difference in clinical data before operation between two groups (P>0.05). However, clearance of hematoma was much faster and more efficient in endoscopic surgical group than in classic surgical evaluation group (1.5 ± 0.4 vs.3.9 ± 0.6 h, P<0.01; 95.84 ± 2.72% vs.87.48 ± 7.84%, P<0.01). The GCS scores were 10(6,12),12(8,13) and 13(10,13) in endoscopic surgical group whereas were 6(5,9),7(5,11).8(5, 12) in craniotomy group at 1,3 and 7 d followed operation. GCS scores were higher in surgical group than in craniotomy group at all time points (P<0.01). In addition, patients receiving endoscopic treatment showed a shorter NICU admission time than those receiving craniotomy (3.55±4.21d vs. 9.10±4.72d, P<0.01). The intracranial infection and hypostatic pneumonia were sig?nificantly lower in endoscopic than in craniotomy surgery group (0 vs.6 cases; 5 vs. 41 cases, P<0.05). The endoscopic treatment significantly improved the GOS score compared with craniotomy [3(3, 4)vs. 2(2, 3)] (P<0.01). Conclusion Endoscopic evacuation of hematoma for hypertensive intracerebral hemorrhage is efficient and minimally invasive, which is superior to craniotomy.

Objective To identify the association of thyroid stimulating hormone receptor ( TSHR ) gene intron 1 susceptible loci and 4p14 susceptible locus rs6832151 polymorphisms with Graves’ disease ( GD) in Han Chinese population in Bengbu, Anhui, China. The gene-gene interaction among TSHR intron 1 susceptible loci and 4p14 susceptible locus rs6832151 was also investigated. Methods The genotypes of the single-nucleotide polymorphisms ( SNPs) were analyzed by Taqman probe technique on Fluidigm EP1 platform in 611 patients with GD and 555 control subjects, and linkage analysis, correlation analysis, haplotype analysis, and epistasis analysis with them were performed. Results Six SNPs in two candidate genes(rs12101261, rs4903964,rs179247, rs2284722 and rs17111394 in TSHR, rs6832151 in 4p14) were associated with GD (all P<0. 05). The frequency distributions of haplotypes of SNPs in TSHR intron 1 ( AGTA, GGCG, AATA, and CC) were significantly different between GD and control groups(all P<0. 01). There existed the interactions between rs179247 and rs12101261 in TSHR(P=0. 001) and among rs179247(TSHR),rs4903964(TSHR) and rs6832151(4p14) (P=0. 001). Conclusions rs683215 in 14p14 and rs12101261, rs4903964, rs179247, rs2284722 and rs17111394 in TSHR intron 1 were susceptible loci of GD in the Chinese Han population from Bengbu. The haplotypes in TSHR intron 1 were associated with GD. There exists the interaction between the SNPs in TSHR and 4p14,which may change the risk of GD.

Objective To study the changes and significance of serum intestinal fatty acid binding protein (IFABP) in children with traumatic brain injury(TBI) complicaled with acute gastrointestinal injury (AGI). Methods A total of 95 children suffering from TBI hospitalized in the PICU of the First Affiliated Hospital of Zhengzhou University from January 2017 to March 2018 were enrolled in the study. According to the modified Glasgow coma score combined with clinical classification criteria for acute closed head injury, the cases were devided into mild(43 cases),moderate (23 cases),and severe(29 cases). Children were gra-ded according to AGI (AGI Ⅰ42 cases,AGI Ⅱ 30 cases,AGI Ⅲ 13 cases,and AGI Ⅳ 10 cases). Thirty healthy children who underwent physical examination at outpatient service were enrolled as the control group. Blood samples were collected at the time of admission and on the 3rd day after admission. Serum IFABP was detected by ELISA,and the differences of serum IFABP concentrations were compared among groups. The correlations between IFABP with TBI classification and AGI grade were analyzed. The receiver operating characteristic (ROC) curve was drawn,and the predictive values of IFABP for the diagnosis of children with TBI complicated with AGI were evaluated. Results On the day of admission,the serum levels of IFABP in mild,moderate and severe brain injury group were significantly higher than that in control group (all P <0. 01). And serum IFABP concentration gradually increased with the increase of brain injury (all P < 0. 01).Serum IFABP levels in children with AGI grade Ⅰto Ⅳ were significantly higher than those in control group (all P < 0. 01). The levels of serum IFABP also increased with the increase of AGI level (all P < 0. 01). The concentration of serum IFABP was positively correlated with the grade of TBI and AGI (rs = 0. 82,P < 0. 01;rs = 0. 70,P < 0. 01). In each group,the levels of serum IFABP on the 3rd day after admission were lower than those on admission (all P < 0. 01). The ROC curve analysis showed that serum IFABP was of high diag-nostic value in children with TBI complicated with AGI,and the area under the ROC curve was 0. 88. When the cutoff value of IFABP was 431. 36 ng/ L,the sensitivity and specificity were 71. 61％ and 90. 00％ ,re-spectively. Conclusion Serum IFABP can be used as a sensitive indicator for the early diagnosis and disease assessment in children with TBI complicated with gastrointestinal dysfunction.

Objective: To analyze the disease burden and trend of attention deficit hyperactivity disorder (ADHD) in China from 1990 to 2019, so as to provide the basic theoretical basis for the health administrative departments to formulate policies. Methods: Using the 2019 Global Burden of Disease Database, the incidence, prevalence and disability adjusted life year (DALY) rates of ADHD were analyzed for both sex and different age groups, and the trends of ADHD were predicted. Results: In 2019, the incidence, prevalence and DALY rate of ADHD in China were 70.41/100 000, 1 546.15/100 000 and 18.87/100 000 respectively. Compared with 1990, the rates decreased by 27.30%, 25.35% and 55.80% respectively, and these rates of females were lower than those of males. In 2019, the incidence rate of ADHD was the highest in the age group 5-9 years old (837.76/100 000), while the highest prevalence and DALY rates were found in ages groups of 10-14 years old (5 740.47/100 000 and 70.49/100 000). The results of the Joinpoint regression model showed that the incidence, prevalence and DALY rate had a downward trend from 1990 to 2019. The AAPC was -1.35%, -1.16% and -1.16%, respectively, with a statistically significant difference ( P <0.05). The prediction results of grey prediction model GM (1,1) indicated that the incidence and prevalence rate of ADHD in China would decline from 2020 to 2030. Conclusion The burden of ADHD in China showed a decreasing trend from 1990 to 2019, indicating that the prevention and treatment effect of ADHD in children and adolescents of China was effective. China should take active preventive measures to reduce the burden of ADHD in children and adolescents.

Objective To evaluate the value of stroke prognostication using age and National Institute of Health Stroke Scale index (SPAN) for outcome after early endovascular treatment for anterior circulation large vessel occlusion.Methods The patients who underwent early endovascular treatment were prospectively,sequentially collected in Yijishan Hospital of Wannan Medical College from December 2014 to September 2017 and Jinling Hospital from March 2014 to March 2017.Individuals whose age in years plus NIHSS score was greater than or equal to 100 were designated as SPAN-100-positive patients,while those with a score less than 100 were designated as SPAN-100-negative patients.We compared the baseline data and perioperative data between the two groups.The 90 days modified Rankin Scale score≤2 was regarded as favorable outcome.Single factor and multivariable Logistic regression analyses were used to determine the association between SPAN-100 and outcomes.Results One hundred and ninety patients were enrolled,20 (10.5％) of which were SPAN-100 positive,and 170(89.5％) were SPAN-100 negative.There were no significant differences between the two groups on postoperative intracerebral hemorrhage and 90 days mortality.Ninety days independence rates were higher in SPAN-100-negative patients (77/170,45.3％) than in SPAN-100 positive patients (4/20,20.0％;x2 =4.681,P =0.030).Multi-factor Logistic regression analysis showed that the higher preoperation systolic pressure (OR =1.030,95％ CI 1.008-1.052,P =0.007),the lower Alberta Stroke Program Early CT Score (OR =1.609,95％ CI 1.056-2.453,P =0.027) and poor collateral circulation(OR =5.714,95％ CI 1.668-19.570,P =0.006) were the independent risk factors of outcomes.Conclusion SPAN-100 is not an independent predictor of favorable outcome after adjusting for factors of outcomes in patients with anterior circulation large vessel occlusion.

Objective:To investigate the relationship of eosinophil cationic protein (ECP) levels in sera and blister fluids with bullous pemphigoid (BP) .Methods:From January 2012 to October 2019, 40 patients with newly diagnosed BP and 40 healthy individuals were enrolled from Department of Dermatology, Peking Union Medical College Hospital, and serum ECP levels were detected by enzyme-linked immunosorbent assay. Meanwhile, another 33 patients with newly diagnosed BP and 41 patients with non-autoimmune bullous diseases were enrolled, and the ECP level was detected in blister fluids by enzyme-linked immunosorbent assay. Pathological sections of skin lesions of 1 patient with BP and 1 with contact dermatitis were subjected to immunohistochemical staining for ECP. Normally distributed data were compared between 2 groups by using t test or t′ test, while enumeration data were compared by using chi-square test. Pearson′s correlation coefficient was used to analyze the relationship between serum levels of ECP and proportions of peripheral blood eosinophils in patients with BP. Results:The serum level of ECP was significantly higher in the BP group (116.9 ± 19.3 ng/L) than in the healthy control group (93.3 ± 15.9 ng/L, t = 5.96, P<0.001) , and the blister fluid level of ECP was also significantly higher in the BP group (665.8 ± 189.0 ng/L) than in the non-autoimmune bullous disease group (547.5 ± 240.6 ng/L, t = 2.31, P = 0.02) . Immunohistochemical study showed more brown-yellow particles in the cytoplasm of ECP-positive cells in the BP group than in the contact dermatitis group. There was no significant correlation between the serum level of ECP and proportion of peripheral blood eosinophils in the BP patients ( r = -0.15, P = 0.35) . Conclusion:The levels of ECP in the sera and blister fluids markedly increased in the patients with BP, and blister fluid levels of ECP were much higher than serum levels of ECP, suggesting that ECP may be involved in the occurrence of BP.

Objective: The study was designed to analyze the clinicopanthologic characteristics, treatments and outcomes of a series of patients with primary angiosarcoma. Methods: The clinical, surgical and pathological data and treatment of 68 patients with pathologically confirmed angiosarcoma admitted to Peking Union Medical College Hospital from January 1990 to June 2017 was retrospectively analyzed. Kaplan-Meier method and Log rank test were used for univariate survival analysis and Cox regression model was used for multivariate survival analysis. Results: A total of 68 patients were enrolled, 38 were male, 30 were female. The median age at diagnosis was 50.5 years. The time from symptom onset to diagnosis was (7.5±7.5) months. The primary sites included face and scalp, breast, chest wall, lung, heart, liver, spleen, extremities, bones and so on. At diagnosis, the mean size of tumors were (7.4±7.3) cm, 28 patients (41.2%) had localized disease (stage Ⅰ+ Ⅱ) and 40 patients had metastatic disease (stage Ⅲ+ Ⅳ). There were 37 patients treated with surgery alone, three receiving radiotherapy alone, five receiving chemotherapy alone and sixteen receiving comprehensive treatment with 5 underwent surgery plus radiotherapy, three treated by surgery plus chemotherapy, four had surgery plus interventional therapy, two had chemoradiotherapy, one had radiotherapy and interventional therapy and 1 had surgery plus chemoradiotherapy and targeted therapy. Five patients received only palliative treatment, and 2 patients lost follow-up after diagnosed. Fifty patients were followed up with a median overall survival time of 8.5 months. The median survival time of patients with metastatic angiosarcoma was 6.6 months, significantly shorter than that of patients with localized disease (15.0 months, P=0.020). The median survival time of patients with cardiac angiosarcoma was 3.0 months, significantly shorter than that of patients with angiosarcoma at other sites (11.5 months, P=0.010). The median survival time of patients receiving comprehensive treatment was 31.0 months, significantly longer than that of patients without comprehensive treatment (5.6 months, P=0.007). Multivariate analysis showed that staging, heart occurrence and comprehensive treatment were independent factors for the prognosis of primary angiosarcoma (all P<0.05). Conclusions Angiosarcoma is a rare malignancy, and patients with metastatic disease or cardiac occurence have poor prognosis. Comprehensive treatment can improve the prognosis of patients with angiosarcoma.

Objective: To explore the changes in root volume and root resorption in incisor arteries from adult patients with skeletal class Ⅲ malocclusion before and after camouflaged orthodontic treatment and to provide a reference for the clinic. Methods : Thirty permanent dentition adult patients with skeletal class Ⅲ malocclusion were included from the Orthodontic Department. CBCT data of each patient at pretreatment and posttreatment were acquired, and 3D digital root models were reconstructed. The whole and segmented root volumes (cervical part, bodily part and apical part) of the right incisors were calculated. Results: The root volumes (whole, cervical part, bodily part and apical part) posttreatment were smaller than those pretreatment (P<0.001). Maxillary central incisors and lateral incisors showed similar resorption in the cervical root and bodily root and more changes in the apical root, but there was no significant difference (P>0.05). Mandibular central incisors and lateral incisors showed more root resorption in the apical root than in the cervical root and bodily root (P<0.01). The absorption ratio of all segmented roots in each incisor showed a significant difference (P<0.001), and apical absorption was the most obvious. There were no significant differences in root volume change amounts or the absorption ratio of the whole, cervical part and bodily part in all incisors (P>0.05). The absorption ratio showed a significant difference in the mandibular lateral incisors (P = 0.028). Conclusion After camouflaged orthodontic treatment of adult skeletal class Ⅲ malocclusion, incisor root resorption occurred mainly in the apical part, but the cervical and bodily parts should also be considered. There was a high risk of root resorption in the mandibular incisors.
