OBJECTIVE:To explore the effect of Buchang naoxintong capsule on the myocardial perfusion and platelet activation function in patients with acute myocardial infarction (AMI) after PCI. METHODS:100 AMI patients were randomly divided into control group and observation group by parallel random sampling,50 cases in each group. Control group was given conventional PCI, preoperatively chewing 300 mg aspirin+300 mg clopidogrel,postoperatively taking 100 mg/d aspirin+75 mg/d clopidogrel. Observation group was additionally treated 2-4 with Buchang naoxintong capsules(after bracket release),3 times a day,the treatment course for both groups was 7 d,observation period was 1 month. Infarct-related artery myocardial perfusion grade(TMPG)in 2 groups,platelet activation function indexes [CD62P,CD63 and monocyte platelet aggregation (MPA) positive expression rates] before and after treatment,the incidences of adverse cardiac events (MACE) and complications were observed and compared 15 min after PCI. Meanwhile,the incidence of adverse reactions was recorded. RESULTS:After treatment,the cases of TMPG perfusion grade 3 in observation group were significantly higher than control group,the incidence of MACE was significantly lower than control group, with statistical significance(P<0.05);there was no significant difference in the incidences of complications and adverse reactions in 2 groups(P>0.05). Before treatment,there was no obvious difference in CD62P,CD63,MPA positive expression rates in 2 groups;after treatment,CD62P,CD63,MPA positive expression rates in 2 group were significantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). CONCLUSIONS:In PCI treatment of AMI patients,Buchang naoxintong capsule can rapidly improve platelet activation functions,TMPG perfusion,reduce the incidence of MACE,with good safety and no increase of complications.

With the continuous advancement of health informatization and the wide application of medical big data, electronic health records came into being and spread rapidly. However, because electronic health records contain a large amount of private information, privacy protection is the primary consideration for the sustainable development of electronic health records. By analyzing the shortcomings of privacy protection of electronic health records in law, technology, management and protection consciousness, this paper put forward some countermeasures, such as perfecting the relevant laws and regulations of privacy protection of electronic health records, improving the technical level, improving the management defects of electronic health records, and cultivating the privacy protection consciousness of professionals and the public, so as to improve the overall privacy protection level of China’s health records information management system and provide effective protection for the privacy information of Chinese residents’ electronic health records.

Objective:To observe the effect of modified Bazhentang on the nutritional status and immune function of patients with Qi and blood deficiency syndrome in neoadjuvant chemotherapy （NAC） for gastric cancer. Method:One hundred and ten patients were randomly divided into observation group and control group with 55 cases each. Both groups accepted FOLFOX6 protocol. Patients in control group took Jianpi Shengxue tablets orally， 3 tablets/time， 3 times/day. Patients in observation group received modified Bazhentang， 1 dose/day. The course of treatment was six weeks in both groups. Before and after treatment， scores were graded according to patient generated-subjective global assessment （PG-SGA）， Qi and blood deficiency syndrome， and the Revised Piper Fatigue Scale （PFS-R）. Levels of serum total protein （TB）， albumin （ALB）， prealbumin （PAB）， CD4⁺， CD8⁺， helper T lymphocyte 17 （Th17）， regulatory T cell （Treg）， immunoglobulin G （IgG）， IgM， and IgA were detected before and after therapy. Body mass index （BMI） and fat free mass index （FFMI） were measured before and after treatment. Weight loss was recorded， and the acute or subacute toxicity of anticancer drugs was evaluated. Result:The degree of malnutrition in the observation group was lower than that in the control group （Z=2.401，P<0.01）. The levels of TB， ALB and PAB in the observation group were higher than those in the control group （P<0.01）. The CD4⁺， Treg and CD4⁺/CD8⁺ levels in the observation group were higher than those in the control group （P<0.01）. The CD8⁺， Th17 and Th17/Treg levels were lower than those in the control group （P<0.01）. Besides， the levels of IgM and IgA in the observation group were higher than those in the control group （P<0.01）. The PG-SGA score and weight loss in the observation group were lower than those in the control group （P<0.01）. The BMI and FFMI data of the observation group were higher than those of the control group （P<0.05）. The scores of PFS-R and Qi-blood deficiency syndrome were lower than those of the control group （P<0.01）. The incidence of nausea and vomiting in the observation group was 45.45% （25/55）， lower than 65.45% （36/55） in the control group （χ²=4.452，P<0.05）.

Objective: To investigate the effect of transcatheter arterial chemoembolization(TACE) combined with three dimensional conformal radiotherapy(3-DCRT) and hyperthermia on inoperable primary hepatic carcinoma. Methods: This study retrospectively analyzed 96 patients with hepatic carcinoma in the Third Hospital of Chengde between 2014 and 2017 who received TACE or combined therapy (TACE combined with 3-DCRT and hyperthermia). Kaplan-Meier curve was used to compare the overall survival(OS) of the two groups. Results: There were 50 cases in the combined therapy group, 46 cases in the TACE group.The effective rate of the combined therapy group was 76.1%, and that of TACE group was 45.6%, the difference was statistically significant(P=0.028). The overall 6-, 12- and 18-month survival rates of the combined therapy group were 98.0%, 89.9% and 63.1%, respectively, which in the TACE group were 91.3%, 67.3% and 46.8%, respectively, the difference between the two groups was significant(χ²=7.836, P=0.005). The incidence of adverse effect of the combined therapy group was low, only 2 patients(4.0%) developed radiation-induced liver disease(RILD), and the liver function recovered to the normal level after 8 weeks. Conclusion TACE combined with 3-DCRT and hyperthermia is more effective than TACE alone for inoperable primary hepatic carcinoma, and with a low incidence of adverse effect.

To investigate the correlation between the trigiuceride-glucose index and early neurological deterioration（END） in patients with mild ischemic stroke（MIS）. Methods This study was retrospective. Patients with acute MIS who were admitted to the Department of Neurology of the First Central Hospital of Baoding from January 2019 to December 2020 for the first time and within 72 h of onset were consecutively included. The National Institute of Health Stroke Scale（NIHSS） scores were recorded at the time of admission，and fasting venous blood was drawn in the early morning of the following day to determine routine blood，liver function，renal function，lipids and other relevant blood indices，and the trigiuceride-glucose index was calculated ln［TG（mg/dl）×FBG（mg/dl）］/2.The patients were divided into END and non-END groups according to their neurological deterioration. Multi-factor logistic regression was used to analyze the factors associated with the occurrence of END in acute MIS patients，and the subject operating characteristic curve（ROC） was used to evaluate the predictive effect of the trigiuceride-glucose index on END in acute MIS patients. Results A final total of 149 patients with acute MIS were included，39 in the END group and 110 in the non-END group. Multi-factor logistic regression analysis showed that neutrophil ratio（OR 1.054，95%CI 1.009～1.101，P=0.017）、TBIL（OR 0.718，95%CI 0.611～0.845，P<0.001）and trigiuceride-glucose index（OR 5.072，95%CI 1.645～15.640，P=0.005） were independent risk factors for the development of END in patients with acute MIS. The ROC curve analysis showed that the diagnostic cut-off value of trigiuceride-glucose index for END was 1.74 with a sensitivity of 53.8% and specificity of 81.8%. Conclusion Elevated trigiuceride-glucose index is one of the risk factors for the development of END in patients with acute MIS and has a predictive role for the development of END in patients with acute MIS.

Objective　To explore the predictive value of the ratio of C-reactive protein to high-density lipoprotein cholesterol (CHR) for carotid plaque vulnerability in patients with ischemic stroke.Methods　A retrospectively enrolled 349 patients with acute ischemic stroke in the Department of Neurology of Baoding First Central Hospital from January 2019 to January 2020.All subjects underwent ultrasound examination to evaluate the condition of carotid artery plaques,and based on the ultrasound results,they were divided into no plaque group,stable plaque group,unstable plaque group.The differences in risk factors,blood lipids,and inflammatory indicators in each group were compared.The receiver operating characteristic (ROC) curve was used to estimate the predictive value of each index on the vulnerability of carotid plaque.Results　C-reactive protein and CHR of the unstable plaque group were higher than those of the stable plaque group,and the difference was statistically significant (P<0.05).ROC curve shows that CHR can predict carotid plaque instability more reliably than a single C-reactive protein.Conclusion　CHR has high predictive value for carotid artery vulnerable plaque and can be used as a new circulating biomarker to identify carotid artery plaque vulnerability.

Chorioretinal disease has become a significant problem affecting human vision. Abnormal expression of vascular endothelial growth factor(VEGF)leads to increased fundus permeability and neovascularization. Vitreous injection of anti-VEGF agents can rapidly inhibit the level of VEGF in the eye and effectively control the development of the disease. At present, anti-VEGF agents are widely administered in ophthalmology. However, studies have shown that intravitreal anti-VEGF agents can reduce plasma VEGF concentration after entering the circulatory system, and the pointless off-target effects of drugs may lead to systemic adverse reactions. For elderly patients, patients with serious comorbidities, lactating women, premature infants and other special populations, attention should be paid to systemic VEGF inhibition after multiple injections. In this paper, in order to provide reference for clinical anti-VEGF therapy, the pharmacokinetics therapy, systemic adverse reactions, contralateral eye effects, and effects of anti-VEGF on breast milk and preterm infants were discussed, and the systemic effects of vitreous injection of anti-VEGF agents were reviewed.

OBJECTIVE To explore in vitro dissolution and in vivo pharmacokinetics of Luteolin solid dispersion in Beagle dogs. METHODS The dissolution of Luteolin solid dispersion was investigated according to the second method （paddle method） of the “dissolution determination method” in the 2020 edition of Chinese Pharmacopoeia （Part Ⅳ）. UPLC-MS/MS method was established to determine the concentration of luteolin in the plasma of Beagle dogs. Twelve Beagle dogs were randomly divided into luteolin group and Luteolin solid dispersion group， with 6 dogs in each group. They were given relevant medicine orally at the dose of 10 mg/kg luteolin. Blood was collected before medication （0 h）， at 5， 10， 15， 30， 45 min and 1， 2， 4， 6， 8， 10， 12， 24， 48 h after administration. After protein precipitation with acetonitrile， the blood concentration of luteolin in Beagle dogs was determined by UPLC-MS/MS and the major pharmacokinetic parameters were calculated with non-compartmental models by using DAS 3.2.8 pharmacokinetic software. RESULTS The dissolutions of Luteolin solid dispersion in purified water and 0.1% sodium dodecyl sulfate solution was significantly higher than those of luteolin； the dissolution rate reached 95% in 0.1% sodium dodecyl sulfate solution for 120 minutes. The peak concentration （cmax） of luteolin in the Luteolin solid dispersion group of Beagle dogs was 5.62 times higher than the luteolin group， and the relative bioavailability was 348%. Compared with luteolin group， cmax and the area under the drug time curve of luteolin in the Luteolin solid dispersion group of Beagle dogs were significantly increased， while the apparent distribution volume was significantly reduced （P＜0.05）. CONCLUSIONS Luteolin solid dispersion can improve in vitro dissolution and bioavailability of luteolin in Beagle dogs.

AIM:To observe the different effects of three intervention approaches on related biometric parameters in children diagnosed with latent myopia, and to investigate different control effects on children with latent myopia.METHODS:Prospective cohort concurrent controls trials. A total of 60 cases(120 eyes)of children who were initially diagnosed as latent myopia and untreated previously at ophthalmology clinic of the Affiliated Hospital of Chengde Medical University from December 2021 to May 2022 were recruited. They were randomly divided into three groups, with 20 cases(40 eyes)in group A treated with 0.01% Atropine eye drops, 20 cases(40 eyes)in group B treated with vision training with a flip chart, and 20 cases(40 eyes)in group C treated with esculin and digitalis glycosides eye drops. They were followed-up for 12 mo, and the spherical equivalent(SE), axial length(AL), corneal curvature(CC), accommodative facility(AF), and macular retinal thickness of the three groups of children were compared at 6 and 12 mo post-intervention.RESULTS:Significant statistical differences were found in AL, SE and AF of the three groups of children at 6 and 12 mo(all P<0.05), and there were significant differences between 6 and 12 mo after the intervention(all P<0.05). SE and AF in the group B and C were higher than those in the group A(all P<0.05). However, there were no significant differences in CC before and after the intervention(all P>0.05). The retinal thickness of the temporal, nasal, inferior and macular fovea of the outer ring at 6 and 12 mo after intervention in the three groups was significantly different from that at the initial diagnosis(all P<0.05), and there was significant difference between 6 mo and 12 mo after intervention(all P<0.05). There was no significant difference in the retinal thickness of the other macular areas among the three groups before and after intervention(all P>0.05).CONCLUSION:When it comes to preventing and controlling myopia, 0.01% Atropine is more effective than flip chart training and esculin and digitalis glycosides eye drops. Therefore, the administration of 0.01% atropine and the implementation of flip chart training can effectively slow down the advancement of latent myopia.
