Objective To investigate the correlation between interleukin 1β gene-511C/T polymorphism of and essential hypertension in the Yi ethnic group of Yunnan province.Methods-511C/T polymorphism of interleukin 1β gene was detected by PCR-RFLP in 85 Yi patients with essential hypertension(EH group)and 106 Yi healthy people(control group)in Shuanghe Township,Jinning County,Yunnan Province.Genotype and allele frequencies were analyzed by SPSS 27.0 software,and association analysis was performed.Results The frequency distribution of CC,CT and TT genotypes at the mutation site 511 of the IL-1βgene in EH group was 18.82%,44.71%and 36.47%,respectively,and it was 5.66%,26.42%and 67.92%in the control group.The difference in genotype frequency between the two groups was statistically significant(P<0.05).The allele frequency of C and T in EH group was 41.18%and 58.82%,respectively,and the allele frequency of C and T in control group was 18.87%and 81.13%.The frequency difference of alleles between the two groups was statistically significant(P<0.05).Both genotype frequency and allele frequency found in males and females had statistical differences(P<0.05).Conclusions The distribution of IL-1β gene-511C/T polymorphism is related to the incident of essential hyper-tension among the Yi ethnic group Yunnan Province,and is the susceptibility gene of the Yi ethnic group to essen-tial hypertension.

Objective:
To compare the prevalence and genotype distribution of human papillomavirus (HPV) in female cervix and vulva.
Methods:
Gene chip technique was applied to detect HPV and determine HPV genotypes in 251 female patients with cervical and vulvar exfoliated cell samples. Chi-square test using SPSS was used to analyze the differences between the two sites.
Results:
Out of the 251 patients, 121 (48.21%) had the same HPV test result in the cervix and vulva, and 130 patients (51.79%) had different test result . Among them, the cases who were HPV-positive in the cervical and vulvar region were 128 and 149, and the positive detection rates were 51.00% and 59.36%. In addition, the prevalence rates of HPV and high-risk HPV were significantly higher in vulva than cervix (262 vs. 206, 199 vs.154, all

GGGGCC repeat expansions in the C9ORF72 gene are the most common cause of amyotrophic lateral sclerosis and frontotemporal dementia (c9ALS/FTD). It has been reported that hexanucleotide repeat expansions in C9ORF72 produce five dipeptide repeat (DPR) proteins by an unconventional repeat-associated non-ATG (RAN) translation. Within the five DPR proteins, poly-PR and poly-GR that contain arginine are more toxic than the other DPRs (poly-GA, poly-GP, and poly-PA). Here, we demonstrated that poly-PR peptides transferred into cells by endocytosis in a clathrin-dependent manner, leading to endoplasmic reticulum stress and cell death. In SH-SY5Y cells and primary cortical neurons, poly-PR activated JUN amino-terminal kinase (JNK) and increased the levels of p53 and Bax. The uptake of poly-PR peptides by cells was significantly inhibited by knockdown of clathrin or by chlorpromazine, an inhibitor that blocks clathrin-mediated endocytosis. Inhibition of clathrin-dependent endocytosis by chlorpromazine significantly blocked the transfer of poly-PR peptides into cells, and attenuated poly-PR-induced JNK activation and cell death. Our data revealed that the uptake of poly-PR undergoes clathrin-dependent endocytosis and blockade of this process prevents the toxic effects of synthetic poly-PR peptides.

Objective To evaluate the change of clinicopathological features and prognosis of papillary thyroid cancer over a 15-year period.Methods The clinicopathological features and outcomes of papillary thyroid cancer patients were analyzed in three groups according to the time of diagnosis:group Ⅰ (1997-2001),group Ⅱ (2002-2006),and group Ⅲ (2007-2011).Results As time advanced,the average age of papillary thyroid cancer patients increased,tumor stage,like size,extrathyroid invasion and lymph node metastasis decreased dramatically (P < 0.01).The percentage of multifocality and bilaterality increased.The long-term follow up data (median follow up time was 6.6 years),indicated that the 15-year over all survival was 97.8% and the 15-year disease-free survival was 90.2%.Tumor ≥3 cm,bilaterality,extrathyroid invasion,lymph node metastasis and AJCC stage were correlated with tumor recurrence.By multivariate COX-regression analysis only lymph node metastasis and bilaterality were independent risk factors.Conclusion The clinicopathological features of papillary thyroid cancer changed over 15 years,with the percentage of early-staged patients increased.Lymph node metastasis and bilaterality are two risk factors for tumor recurrence.

Objective To explore the effects of hyperbaric oxygen (HBO) on the incidence of complications and treatment efficacy following decompressive craniectomy(DC) in severe traumatic brain injury.Methods A total of 160 patients who underwent DC for severe traumatic brain injury from January 2010 to December 2014 in the Neurosurgery Department of Yantai Yuhuangding Hospital were chosen for the study.The subjects were divided into the HBO group (86 Patients) and the routine treatment group (74 patients) in accordance with different treatment methods.Incidence of complications,changes in EEG at different time points after surgery,the levels of transforming factor-β1 (TGF-β1) and myelin basic protein (MBP) in cerebrospinal fluid,scores of Glasgow Coma Scale as well as scores of Modified Rankin Scale 6 months after surgery were compared between the two groups.Results Following DC in severe traumatic brain injury,the rates of cerebral herniation (31.4%),postsurgical epilepsy (10.5%) and hydrocrania (11.6%) in the HBO group were all obviously decreased(47.3%,23.0%,24.3%),as compared with those of the control group,and statistical significance could be seen,when comparisons were made between the 2 groups (P < 0.05).The incidence of subdural effusion in the HBO group was 32.6%,while that of the routine treatment group was 41.9%,and there was no statistical significance,when comparisons were made between the 2 groups (P > 0.05).In the HBO group,the levels of TGF-β 1 and MBP in the cerebrospinal fluid 14 and 21 days after surgery were significantly decreased,as compared with those of the routine treatment group.The EEG and GCS scores in the HBO group were significantly improved,1 and 3 months after surgery,as compared with those of the routine treatment group.The scores of the modified Rankin Scale of the HBO group,which were obtained 6 months after surgery,were significantly higher than those of the routine treatment group,and statistical significance could be noted,when comparisons were made between the 2 groups (P < 0.05).Conclusions Following decompressive cranioectomyin,HBO in the treatment of severe traumatic brain injury could obviously decrease the rates of cerebral herniation,postsurgical epilepsy and hydrocrania.HBO could also substantially improve EEG and decrease levels of TGF-β 1 and MBP,14 and 21 days after surgery,and improve the prognosis of the patients.

Clinic expert information provides important references for residents in need of hospital care. Usually, such information is hidden in the deep web and cannot be directly indexed by search engines. To extract clinic expert information from the deep web, the first challenge is to make a judgment on forms. This paper proposes a novel method based on a domain model, which is a tree structure constructed by the attributes of search interfaces. With this model, search interfaces can be classified to a domain and filled in with domain keywords. Another challenge is to extract information from the returned web pages indexed by search interfaces. To filter the noise information on a web page, a block importance model is proposed. The experiment results indicated that the domain model yielded a precision 10.83% higher than that of the rule-based method, whereas the block importance model yielded an F₁ measure 10.5% higher than that of the XPath method.
