Objective: To investigate the effect of the modified Baoyuan Tang (BYT) with different doses on macrophage phagocytosis in restrained stress mice Method: 80 mice were randomly divided into 4 groups receiving different dose of BYT (stress only, 5g/kg, 10g/kg, 15g/kg) Using the intracellular phagocytosis in vivo to assess the phagocytosis ratio (Ph R) and phagocytosis index (Ph I) Result: The Ph R was highest in 10g/kg group The average of Ph I was also highest in 10g/kg group, but the difference between 10g/kg group and 5g/kg group had no statistic significance Conclusion:BTY 10g/kg has the best protective effect for decreased phagocytosis caused by restrained stress in mice

Esophageal cancer is one of the common malignant tumors in China.Although it is currently treated by multidisciplinary treatment,esophageal cancer's prognosis is still poor.The occurrence of esophageal cancer is closely related to the metabolism of trace element zinc.Zinc deficiency can induce the development of esophageal cancer by inducing inflammatory reaction and microRNAs imbalance.Zinc ion can play an important role in esophageal cancer by regulating the activity of ion channel.The formed zinc finger protein can function as an oncogene or a tumor suppressor gene in esophageal cancer.Zinc metabolism is accompanied by complex biological changes in the pathogenesis of esophageal cancer,and multiple mechanisms interact and are closely linked.The article reviews the research results of recent years on the mechanism of zinc deficiency,zinc ion-regulated ion channel and zinc finger protein in the development of esophageal cancer.

Objective Analyze the effect of emergency thrombolytic therapy on door to needle time (DNT) in patients with acute ischemic stroke (AIS) and effect.Method Selected 182 cases of AIS patients underwent intravenous thrombolysis at the First Hospital of Qinhuangdao from May 2015 to June 2017.Thrombolytic therapy group (83 cases),for the May 2015-May 2016 after neurological consultation intravenous thrombolysis patients;Emergency thrombolytic group(99 cases),for the June 2016-June 2017 emergency thrombolysis group Emergency Department of intravenous thrombolysis patients.Compare the two groups of DNT,thrombolytic therapy 24 h symptomatic hemorrhage conversion rate,Thrombolysis 24 h,7 dNIHSS score,7 dthrombolysis and 3 months thrombolysis and thrombolysis 3 months improved Rankin score (mRs).Results There was no significant difference in baseline characteristics between the two groups (P＞0.05).Compared with the consultation group,the DNT[(69.77±11.66)min vs (80.12±15.49) min,t=5.745,P ＜ 0.01] of emergency thrombolytic group was significantly shortened,and the good score[39(39.4％) vs 21(25.3％),x2=4.272,P=0.039] at 3 months after treatment was significantly higher (P＜0.05);Treatment of 24 h intracranial hemorrhage conversion rate[12(12.12％) vs 5(6.02％),x2=1.982,P=0.159]、Treatment 7d mortality rate [10(10.10％) vs 6(7.22％),x2=0.464,P=0.496],3 months mortality rate [14(14.14％) vs 11 (13.25％),x2=0.030,P=0.862]、There was no significant difference in the 24h effective rate [57(57.6％) vs 53(63.8％),x2=0.745,P=0.388] and 7d effective rate [50(50.5％) vs 46(55.4％),x2=0.438,P0.508] after treatment (P＞0.05).Conclusions The emergency thrombolytic model can shorten the DNT of rt-PA intravenous thrombolysis in patients with AIS.The safety and efficacy of DNT are not different from the neurological consultation mode,and can improve the good prognosis rate.

Objective:To analyze the status quo of bystander cardiopulmonary resuscitation (BCPR) for out-of-hospital cardiac arrest (OHCA) in Qinhuangdao area and its influence on the prognosis of cardiopulmonary resuscitation (CPR).Methods:Based on the Utstein model CPR database of Qinhuangdao, data of 1 162 OHCA patients admitted to the Health Emergency Dispatch Center of Qinhuangdao City from January 2018 to January 2019 were collected, and they were divided into two groups according to whether BCPR was performed or not. The patients' demographic parameters (gender, age), precardiac arrest parameters (location of cardiac arrest), the parameters of the CPR (first aid response time before hospital, initial diagnosis of causes of cardiac arrest, initial cardiac rhythm) and the parameters of the CPR results [whether to achieve on-site restoration of spontaneous circulation (ROSC) and 30-day survival rate] were collected. Multivariate Logistic regression analysis was performed for the relationship between BCPR and on-site ROSC rate. The social characteristics of bystanders implementing BCPR, including gender, age, occupation, educational background, and acquisition method of CPR knowledge, were analyzed.Results:Among the 1 162 OHCA patients, the patients witnessed by professional medical personnel in nursing homes, hospitals and other places and pre-hospital emergency personnel were excluded. 852 OHCA patients were enrolled, among which only 24 patients obtained BCPR (2.8%), and the remaining 828 patients did not obtain BCPR (97.2%). There were no statistically significant differences in gender, age, location of cardiac arrest, pre-hospital emergency response time, primary diagnosis of cardiac arrest causes and initial cardiac rhythm between the two groups. Compared with the non-BCPR group, the on-site ROSC rate and the 30-day survival rate of the BCPR group were significantly increased [on-site ROSC rate: 16.7% (4/24) vs. 5.2% (43/828), 30-day survival rate: 8.3% (2/24) vs. 1.3% (11/828), both P < 0.05]. Multivariate Logistic regression analysis showed that BCPR [odds ratio ( OR) = 32.132, 95% confidence interval (95% CI) was 11.129-65.471], location of cardiac arrest ( OR = 0.080, 95% CI was 1.212-3.125) and response time during pre-hospital emergency treatment ( OR = 0.121, 95% CI was 0.174-0.816) were important factors for on-site ROSC of OHCA patients (all P < 0.01). A total of 30 bystanders participated in the implementation of OHCA patients' BCPR, excluding 2 bystanders of lost follow-up, 28 bystanders with effective return visit. The 28 bystanders of BCPR practitioners were mainly male (85.7%), the age was mainly 18-40 years old (57.1%), the occupation was mainly in the tourism service industry (21.5%), students (17.9%), soldiers (14.3%) and bus drivers (10.7%), and the education background was mainly junior college or above (85.7%), the methods of acquiring CPR knowledge mainly included APP and new media (42.9%) and lectures (21.4%). Conclusions:The BCPR implementation rate of OHCA in Qinhuangdao was only 2.8%. BCPR can improve the success rate of pre-hospital CPR and the 30-day survival rate of OHCA patients. Targeted selection of tourism service industry, students, military personnel and bus drivers as CPR training targets may obtain more significant social benefits.

Purpose: Gamma-glutamyl transferase (GGT) has been reported as being involved in tumor progression. Previous studies documented a potential relationship between serum GGT level and survival outcome in several types of human malignancies. However, the association between serum GGT levels and response to neoadjuvant chemotherapy (NAC) has not yet been reported. The present study aimed to evaluate the association between pre-therapeutic serum GGT level and the efficacy, long-term survival, and adverse reactions of NAC and to investigate its role in predicting NAC sensitivity in patients with breast cancer. Methods: A total of 129 patients were recruited and stratified into 2 groups according to serum GGT level (< 29 U/L and ≥ 29 U/L). The association between pre-therapeutic serum GGT levels and clinicopathological parameters was examined. The correlation between pre-therapeutic serum GGT levels and pathological complete response (pCR) was analyzed using univariate and multivariate logistic regression. Survival analyses of relapse-free survival (RFS) and disease-free survival (DFS) were performed. Pearson's χ 2 test and multivariate logistic regression model were used to analyze the correlation between pre-therapeutic serum GGT levels and adverse reactions. Results: Pre-therapeutic serum GGT levels were associated with pCR among breast cancer patients treated with NAC. Multivariate analysis showed that low-level GGT significantly increased pCR rate. Patients in the high-level GGT group had poorer survival than those in the low-level GGT group. Subgroup analysis demonstrated that serum GGT level was potentially related to RFS and DFS in the hormone receptor-positive group. Low levels of GGT are significantly associated with a higher incidence of neutropenia. Conclusion Pre-therapeutic serum GGT level is an independent and novel biomarker for predicting the efficiency, prognosis, and adverse reactions to NAC in breast cancer patients.Patients with low pre-therapeutic serum GGT levels are more likely to have higher pCR rates, better RFS and DFS, and higher hematologic toxicity.

OBJECTIVE: To investigate the prehospital intervention based on emergency medical services (EMS) in patients with acute ischemic stroke (AIS) for door-to-needle time (DNT) with intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) impact. METHODS: 112 emergency patients receiving rt-PA intravenous thrombolysis admitted to the First Hospital of Qinhuangdao City based on EMS from June 2016 to December 2017 were enrolled. According to whether or not to receive prehospital interventions, patients were divided into prehospital intervention group (n = 42) and routine treatment group (n = 70). Both groups followed the general principles of first aid, including assessment and support of the airway, respiration, and circulation, and blood glucose, electrocardiogram, and dynamic vital signs were monitored. Based on the general principle of EMS, first-aid personnel in the prehospital intervention group screened suspected acute stroke patients requiring prehospitalization according to Los Angeles prehospital stroke screening table (LAPSS), and established fluid ways, and got blood samples to evaluate rt-PA intravenous thrombolysis and risks. Factors influenced DNT compliance were analyzed through multivariate Logistic regression, which included the education level of the patient, whether there were risk factors related to cerebrovascular disease (hypertension, coronary heart disease, diabetes), visit time, National Institute of Health stroke scale (NIHSS) score, whether received EMS intervention or not. The average DNT, DNT ≤ 60 minutes compliance rate, communication time, and decision time for thrombolysis were compared between the two groups. NIHSS score was used to evaluate the effective rate of thrombolysis for 7 days. The modified Rankin score (mRs) was used to evaluate the neurological function after 3 months of thrombolysis (a mRs score of 0-2 was defined as a good nerve function). RESULTS: Univariate analysis showed that the DNT of patients with NIHSS score > 5 was significantly shorter than those with NIHSS score ≤ 5, and DNT in patients received EMS intervention was significantly shorter than the non-receiver; but education level, visiting time, and risk factors associated with cerebrovascular disease had nothing to do with DNT. Multivariate Logistic regression analysis showed that NIHSS score and EMS intervention were the influencing factors of DNT compliance [NIHSS score: odds ratio (OR) = 0.452, 95% confidence interval (95%CI) = 0.162-1.263, P = 0.030; EMS intervention: OR = 3.077, 95%CI = 1.260-7.514, P = 0.014]. Compared with conventional treatment group, DNT of intravenous thrombolytic in prehospital intervention group was significantly shortened (minutes: 62.00±11.07 vs. 78.03±21.04), DNT ≤ 60 minutes compliance rate was significantly increased [35.7% (15/42) vs. 12.9% (9/70)], communication time [minutes: 4 (3, 6) vs. 6 (5, 9)] and decision-making thrombolytic time (minutes: 5.81±2.48 vs. 6.70±2.15) were significantly shortened, the differences were statistically significant (all P < 0.05). The 7-day effective rate in the prehospital intervention group [33.3% (14/42) vs. 14.3% (10/70), χ² = 5.657, P = 0.017] and the 3-mouth good rate of nerve function [38.1% (16/42) vs. 14.3% (10/70), χ² = 10.759, P = 0.001] were significantly higher than those in the conventional treatment group. CONCLUSIONS Prehospital interventions based on EMS can shorten DNT of intravenous thrombolysis in the patients with AIS, improve treatment efficiency, and improve prognosis.

Objective To investigate the mutations of IDH1,IDH2,p53 gene,and Ki-67 protein expression in different grade of gliomas and identify the association with its clinical relevance. Methods The mutations of IDH1,IDH2 and p53 gene were detected by direct DNA sequencing,and protein expression of Ki-67 was analyzed by immunohistochemistry. The correlations between gender,age,tumor site,differentiation degree and pathological type of patients were analyzed. Results R132H mutation of IDH1 gene was detected in 32.6% samples (14/46 cases),of which the proportion of WHO classification grade Ⅱ was 40.0%,and grade Ⅲ was 58.3%. IDH1 mutations were shown correlated with age,pathology level Ⅱ-Ⅲ,and Ki-67 low expression. p53 mutations were detected in 4 glioblastomas,with mutations located at exon 7,8. IDH1 gene mutation was negatively correlated with Ki-67 expression. Conclusions The proportion of IDH1 gene mutation in different pathological types of gliomas is different,which is the highest in gradeⅡ~Ⅲ. It is suggested that the subtypes should be listed independently by routine tests. Mutations in p53 gene are more common in primary glioblastomas and may be associated with adverse outcomes. The combined detection of DH1,p53 and Ki-67 is conducive to the diagnosis and prognosis of glioma.

Objective To investigate the epidemiologic characteristics of diabetes mellitus (DM) in Uygur residents in Kashgar of Xinjiang.Methods The survey was conducted among the Uygur residents aged ≥ 18 years selected through stratified cluster sampling in Kashgar by means of questionnaire survey,physical examination and basic laboratory test.The prevalence of different groups were calculated and risk factors of DM was analyzed by logistic vegression model.Results A total of 4 608 adults were surveyed.The prevalence of DM was 11.31％ (standardized prevalence:10.59％) and the prevalence was 13.65％ (standardized prevalence:12.34％) in males and 10.04％ (standardized prevalence:9.83％) in females.The prevalence increased with age.The prevalence of DM was higher than the prevalence of impaired fasting glucose (IFG) in people aged ＞60 years,especially in females.The rates of awareness,treatment and control of DM were 28.02％,21.31％ and 5.57％,respectively.Multivariate logistic regression analysis indicated that people aged 45-55,55-65 and ＞65 years had higher risk of DM and the odds ratio were 2.08 (95％CI:1.24-3.48),2.73 (95％CI:1.63-4.56) and 3.90 (95％ CI:2.24-6.78) for men and 2.63 (95％ CI:1.71-4.02),3.14 (95％ CI:2.00-4.94) and 5.56 (95％CI:3.47-8.92) for woman,respectively.Family history of DM (OR=2.88 for men,95％Cl:1.45-5.72;OR=2.52 for women,95％CI:1.49-4.26) and BMI≥28.0 kg/m2 (OR=1.77 for men,95％CI:1.19-2.64,OR.=1.80 for women,95％CI:1.30-2.50) were also risk factors for DM.Conclusion The prevalence of DM was high in Uygur residents in Kashgar,but the rate of awareness,treatment and control of DM were low.It is necessary to improve the detection rate of DM and conduct targeted prevention and control of DM.

Objective To understand the prevalence of dyslipidemia and normal blood lipids level in Uygur diabetes patients in Kashgar prefecture in southern area of Xinjiang.Methods A total of 5 078 local residents aged ≥ 18 years (42.56％ were men) selected through cluster random sampling in Kashgar were surveyed by means of questionnaire survey,physical examination and laboratory test,and 521 diabetes patients were screened.Results The overall prevalence of dyslipidemia in diabetes patients was 59.50％ (310/521) with adjusted rate as 49.39％.Age ≥65 years,overweight,obesity and abdominal obesity increased the risk for dyslipidemia by 0.771 times (95％ CI:1.015-3.088),1.132 times (95％CI:1.290-3.523),1.688 times (95％CI:1.573-4.592) and 0.801 times (95％CI:1.028-3.155) respectively.Compared with males,female was a protective factor for dyslipidemia (OR=0.507,95％CI:0.334-0.769).The overall normal rate of blood lipids level including total cholesterol (TC),triglycerides (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) for type 2 diabetes patients was 11.13％.Female,higher BMI and abdominal obesity were the factors influencing the overall normal blood lipids level.The normal rate of LDL-C level decreased with increase of age,BMI and waist circumferences (trend test x2=18.049,P＜ 0.001;trend testx2=10.582,P=0.001;x2=19.081,P＜0.001),but increased with educational level (trend testx2=9.764,P=0.002).Conclusion The prevalence of dyslipidemia in Uygur diabetes patients in Kashgar was high,however,the overall normal rate of blood lipid level was relatively low.Obesity was the most important risk factor for dyslipidemia in this area.More attention should be paid to dyslipidemia prevention in women.

Objective To investigate the prevalence of hypertension and risk factors in Uygur adults in Kashgar of Xinjiang.Methods A total of 4 748 Uygur adults aged ≥ 18 years selected through cluster random sampling in Shufu county of Kashgar prefecture were surveyed by means of questionnaire survey,physical examination and laboratory test.The prevalence,awareness,treatment and control rate of hypertension of different groups were calculated and risk factors of hypertension was analyzed by using non-conditional logistic regression model.Results The overall prevalence of hypertension was 15.73％ (age-adjusted prevalence was 13.75％).The prevalence rates of hypertension in men and women were 16.36％ (age-adjusted prevalence was 12.96％),15.39％ (age-adjusted prevalence was 14.34％),respectively.The rates of awareness,treatment and control of hypertension were 59.57％,52.74％,21.29％,respectively.The prevalence of hypertension increased with age.Compared with age group 18-34 years,the age groups 55-64,≥65 years had higher risk of hypertension and the OR values were 10.53,20.96 for men and 16.27,33.20 for women.The overweight (OR=1.47 for men,OR =1.82 for women,P＜0.05) and obesity (OR =1.88 for men,OR=2.66 for women,P＜0.05) also increased the risk of hypertension.The groups with family history of hypertension (OR=3.85 for men,OR=2.34 for women,P＜0.05) also had higher risk of hypertension.Hypertriglyceridemia was positively correlated with the prevalence of hypertension in men (OR=1.62,95％CI:1.09-2.41).Conclusions The prevalence of hypertension in Uygur adults in Kashgar area of Xinjiang was at relatively low level.The related risk factors were age,overweight,obesity,family history and hypertriglyceridemia in men and the risk factors were similar in women except hypertriglyceridemia.
