Objective To study the blood pressure control and its influencing factors in community standardized management of hypertension patients,to provide basis for clinical diagnosis and treatment.Methods 120 hypertension patients with community standardized management were selected as study group,another 120 hypertension patients were selected as control group.The blood pressure control was compared between the two groups,and the influencing factors were analyzed.Results The systolic and diastolic blood pressur before treatment between the two groups had no statistically significant differences (all P >0.05).The systolic blood pressure,diastolic blood pressure after admin-istration of the study group were (129.4 ±3.2)mmHg,(87.5 ±2.8)mmgHg,which in the control group were (138.3 ±10.1 )mmHg,(95.7 ±4.3 )mmHg,the differences were statistically significant compared with before treatment (t =9.478,9.074,8.278,8.687,all P <0.05),the differences between the two groups were statistically significant (t =7.654,7.061,all P <0.05).Logistic regression analysis showed that age,body mass index,obesity, smoking,blood pressure level,taste and triglyceride were the influencing factors of blood pressure control (OR =20.564,0.995,0.746,1.092,0.749,1.153,0.854,all P <0.05).Conclusion Community standardized management can enhance the effect of blood pressure control,age,body mass index,obesity,blood pressure level,smoking and so on are the influencing factors.

Objective To establish a pure planarian Dugesiaasexual strain in China.Methods The planarian worms were collected from a wild stream,and then made the worm grow after amputation in the lab.To establish an asexual strain through cutting and culturing for the single worms.Results After ten years and more than ten thousand experiments,an asexual pure planarian strain Dugesia ZB-1 originated from Shandong Zibo area was established.It grows stably under laboratory controlled conditions.Conclusions The establishment of DugesiaZB-1 Priovides a solid foundation for further experiments and promoting planarian research in our country and participation in the field of the international planarian research.

Objective To investigate the effects of DNA methylation on the expression of lympho-cyte activation gene 3 (lag3) in different human T cell lines.Methods A quantitative PCR and a flow cy-tometry analysis were performed to measure the expression of lag3 gene in various T cell lines at mRNA and protein levels.The distribution of CpG sites within the promoter and body of lag3 gene was detected to locate the potential regulatory region(s) (CpG island and CpG island shore).The levels of DNA methylation in each cell line were analyzed.The T cell lines were demethylated with 5-Aza-2′-deoxycytidine (5-Aza-2′-dc) for further investigation on the changes of lag3 gene expression and DNA methylation.Results Jurkat E6-1 cells showed the highest expression level of lag3 gene as compared with J.CaM1.6 and CEM cells.Hyperm-ethylated CpG islands were detected in cells of each cell line.The methylation levels of CpG island shore in J.CaM1.6 and CEM cells were higher than that in Jurkat E6-1 cells.Treatment of J.CaM1.6 and CEM cells with 5-Aza-2′-dc significantly promoted the expression of lag3 gene at mRNA and protein levels as well as the demethylation of CpG island shore.No significant differences with the expression of lag3 gene and the methylation of CpG island were observed in Jurkat E6-1 cells with or without 5-Aza-2′-dc stimulation.Con-clusion Methylation and demethylation of CpG island shore played important roles in regulating the tran-scription of lag3 gene.

【Objective】 To investigate the anemia status of infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture, Gansu Province, and to comprehensively evaluate the differences in feeding behaviors between anaemic and normal children through the infant and child feeding index (ICFI) and feeding knowledge scores, so as to provide reference for the guidance of infants and young children feeding in ethnic minority areas and the promotion of children′s growth and development. 【Methods】 Taking infants and young children aged 6 - 24 months in Linxia Prefecture as the study subjects, a multi-stage random sampling method was used to select children who met the requirements from 5 townships and 5 villages in 7 counties in 2019 and 2020.Periphral blood samples were collected to test the level of hemoglobin, so as to determine the anemia status.Meanwhile, physical examination was performed and a questionnaire survey of guardians was conducted to analyze the association betweenanaemia and feeding patterns 【Results】 A total of 3 901 infants and children were included in this study, of whom 729 (18.70%) were anaemic, with a mean ICFI score of 12.56±2.70 and a mean feeding knowledge score of 1.97±1.01.There was no statistically significant association of low feeding knowledge score and low ICFI with anaemia after adjusting for confounders (P>0.05), Unqualified meat addition in ICFI was a risk factor for anaemia (OR=1.355, P=0.042), while non-bottle feeding in the past 24 hours (OR=0.762, P=0.021), and breastfeeding in the past 24 hours of infants and toddlers aged 12 - 24 months (OR=0.228, P=0.018) were protective factor for anemia in infants and toddlers aged 12 - 24 months. 【Conclusions】 The average prevalence of anemia in infants and toddlers aged 6 - 24 months in Linxia Hui Autonomous Prefecture of Gansu Province is high, but the level of infant feeding and the level of feeding knowledge of caregivers are low.Early adherence to breastfeeding, timely addition of supplementary food, and more comsumpution of meat for children are conducive to preventing anemia.

Objective:To investigate the effect of intraoperative body temperature on prognosis of elderly patients with strangulated small bowel obstruction.Methods:The clinical data of 113 elderly patients with strangulated small intestinal obstruction and perform partial resection and anastomosis admitted to the Affiliated Hospital of Southwest Medical University from December 2017 to June 2022 were retrospectively analyzed. The ROC curve was used to analyze the relationship between the intraoperative body temperature(T) and the prognosis of patients, so as to obtain the optimal cutoff point (Ta). According to the relationship between T and Ta, all patients were divided into hypothermia group (33 cases) (T

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.
