OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective To observe the residual of lumbago and leg pain with contained type(CT)and non-contained type(NCT)lumbar disc herniation(LDH)after transforaminal endoscopic treatment,and to explore the role of hypoxia-inducible factor-1α(HIF-1α)and transient receptor potential vanillate 1(TRPV1)pathway.Methods A total of 68 single-segment LDH patients were selected from July 2021 to October 2022,including 44 males and 24 females;aged 26 to 67 years old with an av-erage of(43.63±11.94)years old;course of disease was 4 to 36(18.91±10.34)months;body mass index was(24.45±4.00)kg·m-2;there were 7 cases of L3.4 segments,32 cases of L4,5 segments,and 29 cases of L5S1 segments.All of them were per-formed with percutaneous intervertebral endoscopic extraction of nucleus pulposus and were divided into contained group(CT group)and non-contained group(NCT group)with 34 cases respectively according to the integrity of outer layer of fibrous an-nulus observed during operation.A total of 17 patients who underwent open surgery for scoliosis or vertebral fracture were se-lected as control group,including 12 males and 5 females;aged 21 to 65 years old with an average of(39.41±12.80)years old;body mass index was(24.86±4.11)kg·m-2.The relative mRNA expression quantity of HIF-1α,TRPV1 in nucleus pulposus were measured by quantitative real-time PCR.The contents of neurokinin 1 receptor(NK1R),nerve growth factor(NGF),vascular endothelial growth factor(VEGF)in nucleus pulposus and the serum substance P(SP)and calcitonin gene-related peptide(CGRP)were detected by enzyme linked immunosorbent assay(ELISA).The threshold of lumbar tenderness was de-tected by a pressure pain meter.The degree of lumbago and lumbar function were evaluated by visual analog scale(VAS)and Oswestry disability index(ODI)separately.The residual rate of postoperative lumbago and leg pain was assessed.Results The mRNA relative expression quantity of HIF-1α and TRPV1,and the contents of NK1R,NGF and VEGF in nucleus pulposus,and the levels of serum SP and CGRP before surgery in the NCT group were higher than those in the CT group(P＜0.05),and those in the CT group were higher than the control group(P＜0.05).At day 7 after surgery,the serum SP and CGRP levels,lum-bago and leg pain VAS scores and lumbar ODI index in two LDH groups were lower than before surgery(P＜0.05),and those in the NCT group were higher than the CT group(P＜0.05),and the threshold of lumbar tenderness in the NCT group was lower than the CT group(P＜0.05).The differences of lumbago and leg pain VAS scores,lumbar ODI index and lumbar tenderness threshold between preoperative and postoperative 7 days in the NCT group were lower than those in the CT group(P＜0.05).The residual rate of lumbago and leg pain at 7 days after surgery in the NCT group was higher than that in the CT group(P＜0.05).Conclusion HIF-1α and TRPV1 pathway promoted the excessive production of NGF,VEGF,NK1R in nucleus pulposus and serum neuropeptides SP and CGRP,which may lead to the higher residual rate of lumbago and leg pain with non-contained lumbar disc herniation postoperative.

Objective We aimed to compare the efficacy and prognosis of percutaneous coronary intervention(PCI)in complex and high-risk patients with coronary heart disease(CHD)treated with extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)assistance,and explore the application value of combined use of mechanical circulatory support(MCS)devices in complex PCI.Methods A total of patients who met the inclusion criteria and underwent selective PCI supported by MCS at the Department of Cardiology,the First Affiliated Hospital of the Air Force Medical University from January 2018 to December 2022 were continuously enrolled.According to the mechanical circulatory support method,the patients were divided into ECMO+IABP group and IABP group.Clinical characteristics,angiographic features,in-hospital outcomes,and complications were collected.The intra-hospital outcomes and major adverse cardiovascular events(MACE)at one month and one year after the procedure were observed.The differences and independent risk factors between the two groups in the above indicators were analyzed.Results A total of 218 patients undergoing elective PCI were included,of which 66 patients were in the ECMO+IABP group and 152 patients were in the IABP group.The baseline characteristics of the two groups of patients were generally comparable,but the ECMO+IABP group had more complex lesion characteristics.The proportion of patients with atrial fibrillation(6.1％vs.0.7％,P=0.030),left main disease(43.9％vs.27.0％,P=0.018),triple vessel disease(90.9％vs.75.5％,P=0.009),and RCA chronic total occlusion disease(60.6％vs.35.5％,P＜0.001)was higher in the ECMO+IABP group compared to the IABP group.The proportion of patients with previous PCI history was higher in the IABP group(32.9％vs.16.7％,P=0.014).There was no statistically significant difference in the incidence of in-hospital complications between the two groups(P=0.176),but the incidence of hypotension after PCI was higher in the ECMO+IABP group(19.7％vs.9.2％,P=0.031).The rates of 1-month MACE(4.5％vs.2.6％,P=0.435)and 1-year MACE(7.6％vs.7.9％,P=0.936)were comparable between the two groups.Multivariate analysis showed that in-hospital cardiac arrest(OR 7.17,95％CI 1.27-40.38,P=0.025)and after procedure hypotension(OR 3.60,95％CI 1.10-11.83,P=0.035)were independent risk factors for the occurrence of 1-year MACE.Conclusions Combination use of ECMO+IABP support can provide complex and high-risk coronary heart disease patients with an opportunity to achieve coronary artery revascularization through PCI,and achieve satisfactory long-term prognosis.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To explore the application value of transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) in preoperative screening of different residual types of atrial septal defect (ASD) occlusion.Methods:A retrospective analysis was conducted on the clinical data of 120 ASD patients who received interventional treatment for atrial septal defect at the Second People′s Hospital of Liaocheng from January 2020 to December 2021. Patients underwent TTE and TEE examinations before surgery, and were divided into two groups based on the results of the preoperative TTE examination: those with strong echogenicity of the defect margin and swing amplitude<5 mm were classified as group A ( n=60); Patients with fine echoes and a swing amplitude of ≥5 mm at the defect margin were classified as group B ( n=60). The study compared the differences in measuring the maximum diameter of atrial septal defect between two groups of patients using TTE and TEE, and evaluated the correlation between the maximum diameter of the defect measured by these two methods and the waist diameter of the occluder. Results:There was no statistically significant difference in the maximum diameter of atrial septal defect measured by TTE and TEE in group A ( P>0.05), while there was a statistically significant difference in group B ( P<0.01). In group A patients, the correlation between the maximum diameter of ASD measured by TTE and TEE and the diameter of the occluder waist was good ( r=0.993, 0.991); In group B patients, the correlation between the maximum diameter of ASD measured by TEE and the diameter of the occluder waist was higher ( r=0.995), significantly greater than the correlation with TTE measurements ( r=0.897). The difference between the waist diameter of the occluder and the values measured by TTE and TEE in group A patients was small and not statistically significant ( P>0.05); The difference between the waist diameter of the occluder and the TEE measurement value in group B patients was significantly smaller than the difference with the TTE measurement value ( P<0.01). Conclusions:For patients with atrial septal defect with strong residual echo and small amplitude of oscillation, TTE and TEE have considerable application value and can be used instead of TEE in case screening; For patients with atrial septal defect with thin residual echoes and large oscillation amplitude, further TEE examination is needed to help surgeons more accurately select suitable occluders.

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

Objective To investigate whether Liuwei Dihuang Pills enhances the antigen cross-presenting ability of dendritic cell(DC)by increasing gap junctional intercellular communication(GJIC),and to explore the mechanisms involved.Methods Western Blot and immunofluorescence were used to observe the effects of Liuwei Dihuang Pills-containing serum on the expression and membrane localisation of gap junction protein connexin43(Cx43)in mouse melanoma cells(B16);Calcein-AM/DiI fluorescence tracer assay was used to observe the effects of Liuwei Dihuang Pills-containing serum on the function of GJIC in B16 cells;flow cytometry was used to observe the role of GJIC in the enhancement of DC antigen presenting ability by Liuwei Dihuang Pills-containing serum;and propidium iodide(PI)/Hoechst staining assay was used to observe the immunocidal effect of CD8+ T-lymphocytes.Results Western Blot and immunofluorescence experiments showed that Liuwei Dihuang Pills-containing serum led to the up-regulation of Cx43 expression;fluorescence tracer experiments proved that the GJIC function of B16 cells was significantly enhanced by Liuwei Dihuang Pills-containing serum;flow cytometry analyses showed that the DC antigen-presenting ability was enhanced by Liuwei Dihuang Pills-containing serum;and the results of PI/Hoechst staining showed that the immuno-killing effect of CD8+T-cells was more significant after the intervention of Liuwei Dihuang Pills-containing serum in B16-OVA.Conclusion Liuwei Dihuang Pills improve the GJIC function by up-regulating the Cx43 expression of melanoma cells,and then enhance the cross-presenting ability of DCs thus activating stronger CD8+ T-cell immunocidal responses.

BACKGROUND:Due to the young age of children,the occipital condyle and foramen magnum are not fully developed,and they are prone to various diseases and injuries in the occipitocervical junction,which requires surgical treatment in severe cases.However,anatomical parameters for the development of the occipital condyle and foramen magnum in children are lacking. OBJECTIVE:To measure the morphological structure of the occipital condyle and foramen magnum by three-dimensional reconstruction technique,and to provide important anatomical parameters for occipitocervical junction lesions,related surgical procedures and forensic identification. METHODS:Imaging data of 389 cases of primitive children and adolescents involved in skull base undergoing spiral CT scanning(247 males and 142 females)aged 1-18 years were collected and divided into 1-3-year-old group,4-6-year-old group,7-9-year-old group,10-12-year-old group,13-15-year-old group,and 16-18-year-old group according to their age.Mimics 16.0 software was used to reconstruct the skull base and measure the length and width of the foramen magnum.A formula was used to calculate the area and index of the foramen magnum.We measured the length,width and height of the occipital condyle,the angle between the long axis and the sagittal axis of the occipital condyle(O-S angle),the included angle between the midpoint of the front and back edges of the foramen magnum and the connection between the back edge of occipital condyle and the intersection point of the foramen magnum(F-O angle),and the included angle between the midpoint of the front and back edges of the foramen magnum and the midpoint of the back wall of the sublingual neural tube(F-H angle).Gender,side and age differences were analyzed among the indicators. RESULTS AND CONCLUSION:(1)In foramen magnum measurement,there was no significant difference between sexes in the index of the foramen magnum(P>0.05),but there were significant differences in length,width and area of the foramen magnum(P<0.05).(2)The O-S angle,F-O angle and F-H angle of the occipitral condyle were not significantly different between genders(P>0.05),but length,width and height of the occipital condyle were significantly different between genders(P<0.05).(3)There were no significant differences in the length of the occipital condyle among different groups(P>0.05),but there were significant differences in the width and height of the occipital condyle,O-S angle,F-O angle and F-H angle among different groups(P<0.05).(4)Length,width and area of the foramen magnum,length,width and height of the occipital condyle showed a wavy increasing trend with the increase of age,while O-S,F-O and F-H angles showed a wavy decreasing trend with the increase of age,while the index of the foramen magnum showed no significant change.(5)In conclusion,there are gender and lateral differences in the morphological indexes of the foramen magnum and the occipital condyle in children.These differences can provide an important reference for clinical surgical approach selection and forensic examination.

Objective To explore the factors associated with laryngeal cancer relapse after postoperative radiotherapy,discuss the relationship between radiotherapy dose under various surgical procedures and relapse,and analyze their effects on survival rate.Methods The clinical data of 134 patients with laryngeal cancer treated with postoperative radiotherapy in Shijiazhuang People's Hospital were retrospectively analyzed.The risk factors of postoperative relapse were analyzed with univariate analysis,followed by multivariate Logistic regression analysis.The relationships between radiotherapy doses under various surgical procedures and the relapse were discussed.Kaplan-meler method and Log rank test were used to analyze the 2-year survival rate of laryngeal cancer patients.Results Thirty out of the 134 patients relapsed after treatment,and there was no recurrence in the remaining 104 patients.Multivariate Logistic regression analysis identified clinical stage(Ⅲ-Ⅳ),T stage(T3-T4),N stage(N1-N3),radiotherapy dose(low-dose),thyroid cartilage invasion(yes)and surgical margin(positive)as independent risk factors for postoperative laryngeal cancer relapse(OR>1,P<0.05).The relapse rates of patients receiving high-dose radiotherapy after laser vocal cord mass resection/partial laryngectomy and total laryngectomy under self-retaining laryngoscope were lower than those of patients receiving low-dose radiotherapy,with a statistically significant difference in overall relapse rate(P<0.05).As of June 2023,the median follow-up time of 134 patients undergoing postoperative radiotherapy for laryngeal cancer was 14.23 months(1-24 months),and there were 8 deaths in low-dose group and 2 deaths in high-dose group.The estimated median survival times in low-and high-dose groups were 19.13 months and 22.13 months.The survival curves in two groups were different(Log rank P=0.20),with high-dose group outperforming low-dose group.Conclusion The overall therapeutic effect of surgery combined with postoperative radiotherapy for laryngeal cancer is favorable.However,clinical stage,T stage,N stage,low-dose radiotherapy,tumor invasion into thyroid cartilage,positive surgical margin,and>11 weeks from postoperation to radiotherapy completion were risk factors for disease relapse.In clinical practice,the radiotherapy dose should be appropriately increased based on the patient's condition to improve prognosis and extend survival duration.

Objective To investigate the effects and the mechanisms of sulforaphane(SFN)on endothelin-1(ET-1)-induced proliferation in rat vascular smooth muscle cell(VSMC).Methods Rat VSMC were cultured by using the modified tissue explant technique in vitro and were randomly divided into control group(normal culture),model group(treated with 0.1 μmol·L-1 ET-1)and experimental-L,-M,-H groups(treated with 5,10,20 SFN+0.1 μmol·L-1 ET-1).The survival rate of VSMC were measured by methyl thiazolyl tetrazolium.The proliferation and apoptosis related genes in mRNA level in VSMC were respectively examined with real-time quantitative polymerase chain reaction;the relative fluorescence intensity of reactive oxygen species(ROS)in VSMC were measured by fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate;the protein expression of B-cell lymphoma-2(Bel-2),cysteinyl aspartate-specific proteinase-3(caspase-3),p38 mitogen-activated protein kinases(p38MAPK),phosphorylated p38 mitogen-activated protein kinases(p-p38MAPK),and p53 in VSMC were investigated by Western blot.Results The proliferation activities of the control group,model group,experimental-L,-M,-H groups were 0.27±0.02,0.50±0.04,0.40±0.03,0.38±0.03 and 0.34±0.03;the expression levels of Bcl-2 mRNA were 1.57±0.28,1.00±0.00,0.87±0.05,0.75±0.08 and 0.41±0.18;the expression levels of caspase-3 mRNA were 0.84±0.10,1.00±0.00,1.33±0.10,1.61±0.15 and 1.83±0.16;the relative fluorescence intensities of ROS in VSMC were 6.05±1.50,31.45±3.12,30.03±1.85,18.39±5.62 and 17.18±1.97;the relative expression levels of Bel-2 protein were 0.65±0.02,0.60±0.02,0.49±0.02,0.48±0.03 and 0.49±0.01;the relative expression levels of caspase-3 protein were 0.03±0.00,0.25±0.01,0.42±0.01,0.46±0.02 and 0.64±0.03;the protein expression ratios of p-p38MAPK/p38MAPK were 0.97±0.05,1.44±0.04,1.62±0.10,2.18±0.05 and 2.70±0.05;the relative expression levels of p53 protein were 0.20±0.01,0.30±0.01,0.34±0.02,0.37±0.01 and 0.42±0.01 respectively.There were statistically significant differences in the above indicators between model group and control group,between model group and experimental-M,-H groups(P＜0.05,P＜0.01).Conclusion These demonstrate that SFN may inhibit proliferation and prompt apoptosis in ET-1-stimulated VSMC by anti-oxidant and activating p38MAPK and p53-depended apoptosis signal pathway.
