OBJECTIVE To explore the effects of intensive pharmaceutical intervention led by clinical pharmacists on hypertension patients with medium and high risk of ischemic stroke. METHODS The hypertension outpatients with medium and high risk of ischemic stroke， who were assessed by the modified Framingham stroke scale in Zhengzhou People’s Hospital from Oct. 2019 to Apr. 2020， were randomly divided into control group and intervention group， with 200 cases in each group. Patients in the control group received conventional treatment without pharmaceutical intervention； on the basis of conventional treatment， patients in the intervention group received 12-month intensive pharmaceutical intervention （grading management of compliance+ regular follow-up， involving medication education and guidance， blood glucose， blood pressure， blood lipid management and healthy life guidance） provided by clinical pharmacists. The blood glucose indexes， blood lipid indexes， blood pressure compliance rate， medication compliance， 10-year stroke risk and stroke incidence were compared between two groups at baseline and 12 months after enrollment. RESULTS After 12 months of enrollment， the level of low-density lipoprotein cholesterol （LDL-C） in intervention group was significantly lower than that in the same group at baseline， and the levels of fasting blood glucose， glycosylated hemoglobin， total cholesterol and LDL-C in intervention group were significantly lower than those in control group at the same time points （P＜0.05 or P＜0.01）. The compliance rate of blood pressure and medication compliance in intervention group were significantly higher or better than those in control group （P＜0.01）. There were 12 and 15 patients in control group and intervention group turned into low-risk ones respectively， and the proportion of high-risk patients in intervention group was significantly lower than that in control group（P＜0.01）， while the proportion of medium-risk patients was significantly higher than that in control group（P＜0.05）； the incidence of stroke in intervention group was significantly lower than that in control group （1.0% vs. 4.5%， P＜0.05）. CONCLUSIONS The pharmaceutical intensive intervention led by clinical pharmacists can reduce blood glucose and blood lipid levels of hypertensive outpatients， improve their blood pressure compliance rate and medication compliance， and help reduce the risk of stroke.

AIM: To evaluate the clinical efficacy of amoxicillin from volume-based procurement (VBP) and potassium amoxicillin clavulanate in the eradication of helicobacter pylori (Hp) infection, providing basis for the selection of treatment programs. METHODS: Data from the patients who received Hp eradication therapy from May 2021 to May 2022 were recruited from the rational drug use management system. The data from the patients treated by amoxicillin (amoxicillin 1.0 g bid + bismuth potassium citrate 220 mg bid + esomeprazole 20 mg bid + clarithromycin 0.5 g bid, for 14 days) and potassium amoxicillin clavulanate (potassium amoxicillin clavulanate 0.914 g bid + bismuth potassium citrate 220 mg bid + esomeprazole 20 mg bid + clarithromycin 0.5 g bid, for 14 days) were selected and compared. RESULTS: A total of 171 cases were collected in the group treated by Amoxicillin program, and the eradication rate was 87.8% (150/171). A total of 69 cases were collected in the group of potassium amoxicillin clavulanate, and the eradication rate was 76.8% (53/69). There was no significant difference in baseline data between the two groups (P>0.05). There was a significant difference in clinical efficacy between the two groups (P< 0.05). In addition, the cost-effectiveness ratio (C/E) of the Amoxicillin treatment program was lower than that of the potassium amoxicillin clavulanate program CONCLUSION: The clinical efficacy of VBP Amoxicillin program in eradicating Hp infection is better than that of the potassium amoxicillin clavulanate program, which is worthy of clinical recommendation.

Using machine learning algorithms to construct an early prediction model of brucellosis to improve the diagnosis efficiency of Brucellosis. This study was a case-control study. 2 381 brucellosis patients from Beijing Ditan Hospital affiliated to Capital Medical University were retrospectively collected as case group, and healthy people from Beijing Chaoyang Hospital affiliated to Capital Medical University were collected as control group from May 9, 2011 to November 29, 2021. The relevant clinical information and full blood count results of 13 257 data were collected and five algorithms of machine learning were used to construct an early predication model of brucellosis by using machine learning: random forest, Naive Bayes, decision tree, logistic regression and support vector machine;14 074 data (2 143 cases incase group and 11 931 cases in control group) were used to establish the early predication model of brucellosis, and 1 564 (238 cases in case group and 1 326 cases in control group) data were used to test the predication efficiency of the brucellosis model. The results showed that the support vector machine algorithm has the best predication performance by comparing the five machine learning models. The area under receiver curve (AUC) of receiver operating characteristic (ROC) was 0.991, and the accuracy, precision, specificity and Recall were 95.6%, 95.5%, 95.4% and 95.9%, respectively. Based on the SHAP plot, platelet distribution width (PDW) and basophil relative value (BASO%) results were low, and men with high coefficient of variation (R-CV), erythrocyte hemoglobin concentration (MCHC), and platelet volume (MPV) were predicted to be at high risk of brucellosis. Platelet distribution width (PDW) contributed the most to the prediction model, followed by red blood cell distribution width coefficient of variation (R-CV). In conclusion, the establishment of a high-precision early predication method of brucellosis based on machine learning may be of great significance for the early detection and treatment of brucellosis patients.

Objective:To preliminary explore the potential application value of ultrasound shear wave elastography (SWE) in assessing functional defecation disorders compared with anorectal manometry and X-ray defecography.Methods:From July 2022 to December 2022, the results of SWE, anorectal manometry and X-ray defecography of 39 patients with functional defecation disorders visited Sir Run Run Shaw Hospital, School of Medicine of Zhejiang University were retrospectively analyzed. Non-parametric tests were used to analyze the changes in elastic modulus values of anorectal muscle groups at different phase.Chi-square test and Bland-Altman plots were used to assess the consistency between SWE, X-ray defecography and anorectal manometry in evaluating spastic pelvic floor syndrome, as well as the changes in the anorectal angle measured by SWE and X-ray defecography (from resting phase to contraction phase, resting phase to strain phase (Valsalval maneuver).Results:The elastic modulus values measured by SWE of the puborectalis muscle, internal anal sphincter, and external anal sphincter of patients with functional defecation disorders during strain phase were 32.4 kPa (19.1 kPa, 60.3 kPa), 25.3 kPa (17.0 kPa, 53.8 kPa), and 28.6 kPa (21.3 kPa, 55.1 kPa), respectively, which had no statistically significant differences compared to elastic modulus values in resting phase (33.5 kPa (22.1 kPa, 44.9 kPa), 28.9 kPa (22.4 kPa, 45.1 kPa), and 32.4 kPa (23.1 kPa, 49.4 kPa), all P>0.05). The consistency between SWE and X-ray defecography in the diagnosis of spastic pelvic floor syndrome was poor (Kappa=0.190). The consistency between SWE and anorectal manometry in the diagnosis of dyssynergic defecation was poor (Kappa=0.160). The differences in the changes of anorectal angle detected by SWE and X-ray defecography were within the 95% consistency limit ( P=0.429 and 0.582). Conclusion:SWE is sensitive in evaluating changes in anorectal angle, and it shows good consistency with defecography in assessing angle changes.

Objective To improve the quality control of Dilong Shenmai oral liquid. Methods TLC was used for the qualitative identification of Astragali Radix, Ophiopogonis Radix and Schisandrae Chinensis Fructus in Dilong Shenmai oral liquid. HPLC was used to determine the contents of schisandrin and ethylparaben in the preparation. Wondasil C₁₈ column (250 mm×4.6 mm, 5 μm) was used with acetonitrile-water as the mobile phase at the flow rate of 1.0 ml/min for gradient elution. The detection wavelength was set at 254 nm, and column temperature was 30 ℃. Results TLC spots were clear and well-separated without negative interference. The linear ranges of schisandrin and ethylparaben were 5.81−58.06 μg/ml (r=0.999 9) and 25.29−252.94 μg/ml (r=0.999 9). The average recoveries were 99.35% (RSD=1.02%) and 99.72% (RSD=0.76%). Conclusion This method is simple, quick and accurate. It can be used for effective quality control of Dilong Shenmai oral liquid.

OBJECTIVE: To analyze clinical features, surgical treatment and outcomes of neurilemmoma and carotid body tumors in bifurcation of carotid artery. METHODS: The clinical data of 17 patients with neurilemmomas and 76 patients with carotid body tumors at the bifurcation of carotid artery, who were surgically treated in Zhongshan Hospital of Fudan University from March 2012 to November 2016, were retrospectively analyzed. The clinicopathological characteristics, surgical procedures and outcomes were compared between two groups. RESULTS: No difference of preoperative clinical demographic data was found between two groups. Operation time of the neurilemmoma group was significantly shorter than that of the carotid body tumor group[(93.9±30.8) min vs. (159.3±52.9) min, <0.01]. The neurilemmoma group had lower volume of intra-operative blood loss[(110±96) mL vs. (356±239) mL, <0.01] and lower rate of external carotid artery resection (11.8% vs. 68.4%, <0.01) than the carotid body tumor group. In the neurilemmoma group, 17 tumors were completely resected and no malignant disease was found. In the carotid body tumor group, 76 patients underwent complete surgical resection for the tumor, of which 5 (6.6%) were malignant. Tumor size of the neurilemmoma group was larger than that of the carotid body tumor group[(4.5±1.4) cm vs. (3.1±1.0) cm, <0.01]. There was no significant difference in the incidence of peri-operative complications and length of hospital stay between two groups (>0.05). CONCLUSIONS The clinical manifestations of neurilemmoma and carotid body tumors at carotid artery bifurcation are similar. The carotid body tumor group has a longer operating time, larger intra-operative blood loss, higher external carotid resection rate and relative higher incidence of malignancy. More cautions should be given when carotid body tumors at carotid artery bifurcation are treated.
