OBJECTIVE To introduce the characteristics and practice of billable pharmacy service programs in the United States， aiming to provide reference for the development of clinical pharmacy service and the establishment of corresponding billing criteria in China. METHODS By searching the official websites of American Pharmacists Association， American Society of Health- System Pharmacists， Centers for Medicare & Medicaid Services and Centers for Disease Control and Prevention， and the PubMed database， the contents of American billable pharmacy service programs， corresponding service billing criteria， the approaches to being paid as pharmacists and the clinical practice evidence were summarized. RESULTS Current major billable pharmacy service programs implemented in the United States included medication therapy management， outpatient pharmacy service， transition of care management， chronic disease management， annual wellness visits， as well as diabetes self-management training/education. Except for diabetes self-management training/education， which lacked robust data on practice outcomes， all other programs mentioned above were demonstrated to have positive impact on patient outcomes， reducing health care cost and/or generating revenues. The most common approaches for pharmacists to obtain reimbursement were “incident to” billing and using procedure codes. CONCLUSIONS Billable pharmacy practice programs in the United States are achieving progress in service specialization and billing standardization. China can learn from successful cases in the United States while considering its own national context， with the ultimate goal of improving the overall health outcomes of patients， so that pharmacy services can become an important part of the medical service system.

Objective To investigate the effects of esketamine on respiration,complications and acute phase inflammatory factors in patients undergoing single-port thoracoscopic surgery under general anesthesia with preserved spontaneous respiration.Methods Ninety patients,aged 16～74 years,BMI 18～28 kg/m2,ASA physical status Ⅰ or Ⅱ,who were scheduled to undergo single-port thoracoscopic surgery under general anesthesia were selected.Patients were randomly divided into two groups by random number table:esketamine group(group E,n=45)and control group(group C,n=45).Esketamine 0.5 mg/kg was given for induction of anesthesia,and 0.25 mg/kg again before cutting skin.In group C,sufentanilwas given at 0.15 μg/kg for induction of anesthesia.Other anesthesia induction and maintenance durgs in both groups were the same.SP02,PaCO2 and PaO2 were recorded at the patient's entrance(T0),before pleuraopening(T1),15 min after pleuraopening(T2),30 min after pleuraopening(T3),and beforelaryngeal mask removal(T4).3 mL of blood was extracted from themedian cubital vein at T0 and 24 h after surgery(T5)todetect the concentrations of TNF-α and IL-6.The length of spontaneous respiration recovery and laryngeal mask removal,the number of respiratory intervention,the incidence of body movement during operation,nausea,vomiting,psychiatric symptom,awareness,the length of hospital stay was recorded.Results Compared with group C,PaO2was significantly decreased and PaCO2was significantly increased in group E at T1,PaO2was significantly increased and PaCO2was significantly decreased at T2(P<0.01).Compared with group C,the length of spontaneous respiration recovery was significantly shortened and the number of respiratory intervention was significantly decreased in group E(P<0.01).Compared with group C,the concen-trations of TNF-α and IL-6 in venous blood in group E at T5 was significantly decreased(P<0.01).There were no significant difference in the length of laryngeal mask removal,and the incidenceofcomplications,hospitalstay between the two groups.Conclusion Esketamine reducesintraoperative respiratory depression,shortens spontaneous respiration recovery,maintains respiratory stability and reduces acute inflammatory response in patients under general anesthesia with preserved spontaneous respiration for single-port thoracoscopic surgery.

Objective:Type H blood vessels are a subtype of bone-specific microvessels(CD31hiEmcnhi)that play an important regulatory role in the coupling of angiogenesis and osteogenesis.Despite reports on the distinct roles of type H and L vessels under physiological and pathological bone conditions,their genetic differences remain to be elucidated.This study aims to construct a competitive endogenous RNA(ceRNA)network of key gene for differencial expression(DE)in type H and L vascular endothelial cells(ECs)through integrated bioinformatic methods. Methods:We downloaded relevant raw data from the ArrayExpress and the Gene Expression Omnibus(GEO)database and used the Limma R-Bioconductor package to screen for DE lncRNAs,DE miRNAs,and DE mRNAs between type H and L vascular ECs.A total ceRNA network was constructed based on their interactions,followed by refinement using protein-protein interaction(PPI)networks to select upregulated and downregulated key genes.Enrichment analysis was performed on these key genes.Random validation was conducted using flow cytometry and real-time RT-PCR. Results:A total of 1 761 DE mRNAs,187 DE lncRNAs,and 159 DE miRNAs were identified,and a comprehensive ceRNA network was constructed based on their interactions.Six upregulated(Itga5,Kdr,Tjp1,Pecam1,Cdh5,and Ptk2)and 2 downregulated(Csf1r and Il10)key genes were selected via PPI network to construct a subnetwork of ceRNAs related to these key genes.Upregulated key genes were mainly enriched in negative regulation of angiogenesis and vascular apoptosis.Results from flow cytometry and real-time RT-PCR were consistent with bioinformatics analysis. Conclusion:This study proposes a ceRNA network associated with upregulated and downregulated type H and L vascular ECs based on selected key genes,providing new insights into the regulatory mechanisms of type H and L vascular ECs in bone metabolism.

Objective:To compare the clinical efficacy of robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Medical Journal Full-text Database, PubMed, Web of Science and ScienceDirect were searched for literature on robot-assisted versus fluoroscopy-assisted sacroiliac screw internal fixation for posterior pelvic ring fractures. The search time was from the establishment of each database to March 2023. Meta-analysis was performed on the included literature. The random-effects model was used when the heterogeneity between groups was large, and the fixed-effects model was used when the heterogeneity between groups was small.Results:A total of 15 studies were included in the meta-analysis, including 465 patients in the robot-assisted group and 396 patients in the fluoroscopy-assisted group. Meta-analysis showed that the number of fluoroscopies [ SMD=-3.12, 95% CI (-4.34, -1.89), P<0.001], the number of guide pin adjustments [ SMD=-3.75, 95% CI (-6.77, -0.72), P=0.015], intraoperative blood loss [ SMD=-0.83, 95% CI (-1.18, -0.49), P<0.001], and operative time [ SMD=-2.59, 95% CI (-4.11, -1.08), P<0.001] were smaller than those in the fluoroscopy-assisted group. The rate of excellent screw implantation [ OR=10.13, 95% CI (3.67,27.98), P<0.001] of the robot-assisted was larger than the fluoroscopy-assisted group. There was no significant difference in Majeed functional score [ SMD=0.28, 95% CI (-0.0003, 0.55), P=0.050] and fracture healing time [ SMD=-0.14, 95% CI (-0.46, 0.17), P=0.367] between the two groups. Conclusion:Robot-assisted percutaneous sacroiliac screw fixation for posterior pelvic ring fractures has the advantages of less fluoroscopy, less guide pin adjustment, less intraoperative blood loss, shorter operation time, and higher rate of excellent screw position. However, there is no difference in Majeed score and fracture healing time between robot-assisted percutaneous sacroiliac screw fixation and fluoroscopy-assisted percutaneous sacroiliac screw fixation.

Objective To evaluate the efficiency and safety of micropulse laser trabeculoplasty (MLT) for open angle glaucoma ( OAG) patients and ocular hypertension ( OHT) patients. Methods A prospective self-controlled study was designed. Fifty-six eyes of 56 OAG and OHT patients in Peking University Third Hospital were recruited from June 2016 to June 2017,including 32 males and 24 females with the age of (50. 4±19. 0) years old. The diagnosis included 48 eyes of primary open angle glaucoma (POAG),3 eyes of normal tension glaucoma and 5 eyes of OHT. The best corrected vision acuity ( BCVA) was 0. 7 ±0. 3 before treatment. The intraocular pressure (IOP) before MLT was (20.4±5.8) mmHg,the average types of antiglaucoma medications was 1.7,including systemic medication and local drug use. The general information, BCVA, IOP and antiglaucoma medication were recorded. Only one eye of each patient was treated by MLT. The IOP at different follow-up time points (2 hours, 1 day,1 week, 1 month, 3 months post-treatment) and the number of antiglaucoma medication before and after treatment were compared. This study protocol was approved by Ethic Committee of Peking University Third Hospital (No. 2014166). Written informed consent was obtained from each subject prior to any medical examination. Results The IOP after MLT was (20. 2±6. 7),(17. 6±4. 4),(18. 1±4. 5),(17. 4±3. 4) and (17. 0±2. 1)mmHg at 2 hours, 1 day,1 week,1 month and 3 months,respectively,with significant difference among the different time points ( F=7. 320,P<0. 001). Compared with the IOP before treatment,the IOP at 1 day,1 week,1 month and 3 months after treatment were significantly decerased,with significant differences between them (all at P<0. 05). Three months after treatment,the average number of glaucoma medications used was 1. 5, and only local administration was used. Infection,hyphema,cornea injury,burns and other complications were not seen in all the patients. Conclusions MLT is effective and safety for OAG and OHT patients,and reduce the use of glaucoma drugs.

OBJECTIVE: To purify and identify HMGB1 secreted by liver cells HepG2 and immune cells U937. METHODS: We cultured the liver cell lines HepG2 and immune cell lines U937, and stimulated them with HMGB1 (400 ng/mL) for 20 h. Then the supernatant was collected. Ultrafiltration centrifugation, CM-Sepharose cation, DEAE-Sepharose anion exchange chromatography, Sephadex G75-gel filtration chromatography, and immunoprecipitation were used for purification. The molecular weight and identity of HMGB1 was confirmed by SDS-PAGE and Western blot. RESULTS: A sharp stained protein band with a molecular weight of about 26 kD was obtained by SDS-PAGE analysis and shown to be HMGB1 confirmed by Western blot. CONCLUSION High purified HMGB1 can be separated from these two cell lines.

Objective To analyze the changes of heart rate turbulence (HRT) and heart rate variability (HRV) in coronary heart disease (CHD), and evaluate the relationship between CHD and coronary artery disease (CAD) and two parameters of HRT and HRV, and investigate the correlation between the 2 parameters.Methods We performed coronary angiography in all 103 patients with CHD (group A), who were classified into 3 subgroups: 35 patients of stable angina pectoris ( group A1 ), 28 patients of unstable angina pectoris ( group A2 ) and 40 patients of AMI ( group A3 ), and 30 structurally normal patients with ventricular premature contraction who were included in healthy control group ( group B).The 24-hour ambulatory electrocardiogram was performed in all the patients, and the parameters of HRT and HRV were obtained.Results The value of the TO onset of group A was significantly higher than that of group B( -4.17± 2.75, - 3.16 ± 3.18, - 0.96 ± 2.92; - 6.30 ± 3.47 ), the value of TS of group A was lower than that of groupB(6.81±3.18,5.12±3.31,3.20±1.71;9.52±3.85) (P ＜0.05 orP ＜0.01).The values of SDNN, PNN50, and HF of group A were significantly lower than those of group B (P＜ 0.05).TO was positively correlated with Gensinies score, while TS, SDNN, PNN50 and HF were negatively correlated with Gensinies score, and TS showed the strongest negative correlation with Gensini score (r=-0.45).TO was negatively correlated with SDNN, PNN50, and HF, while TS was positively correlated with SDNN, PNN50 and HF, and TS showed much stronger correlation with HF (r=0.47).Conclusions HRT was dramatically blunted and HRV in patients with CHD was significantly lower;.HRT and HRV of group A1 were significantly correlated with Gensini score, and TS had the strongest correlation with Gensini score.TO and TS were correlated with SDNN, PNN50 and HF, and TS had much stronger relationship with HF.

OBJECTIVE: To evaluate the efficacy and safety of implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy-defibrillators (CRT-D) avoiding defibrillation threshold (DFT) testing when treating ventricular tachycardia (VT) or ventricular fibrillation (VF). METHODS: We analyzed a continuous database of the 21 patients who had avoided DFT during ICD implantation from Oct. 1999 to Aug. 2008. Follow-up data were completed and analyzed in the 21 patients with ICD implantation. RESULTS: ICDs were implanted successfully in 17 patients with VT or VF, and CRT-D were implanted successfully in 4 myocardiopathy patients with severe heart failure who avoided DFT during ICD or CRT-D implantation. Eight patients accepted DFT 1 week later, VT or VF was not induced in 3 patients (37.5%). During the mean follow-up of 1 approximately 7 (4.2+/-1.9) years, malignant ventricular arrythmia was recorded in 16 patients. Among them, 89 episodes were successfully terminated by defbrillation (100%), 120 VT events were terminated by the first run of antitachycardia pacing (51.1%) and 22 by low energy cardioversion (59.2%). All patients took antiarrhycardia drugs after ICD or CRT-D implantation. No patient died from malignant ventricular arrythmia during the follow-up. CONCLUSION No application of routine DFT may avoid complications associated with DFT during ICD or CRT-D implantation. ICD or CRT-D implantation may effectively treat fatal ventricular tachyarrhythmias and prevent sudden cardiac death.
