AIM: To investigate the guiding role of individualized medication adjustment based on CYP2C19 metabolic typing in the treatment of ischemic stroke with clopidogrel, and to provide reference for clinical individualized medication. METHODS: The total of 80 patients with ischemic stroke were divided into the individualized drug instruction group with gene detection (n=40) and the control group without gene detection (n=40) according to whether they received CYP2C19 gene detection. According to the metabolism of CYP2C19, the individualized medication instruction group was divided into slow metabolic type, intermediate metabolic type, fast metabolic type and ultra-fast metabolic type. Patients with fast and ultra-fast metabolites were given clopidogrel dose of 75 mg once a day. Patients with intermediate metabolic type were given double clopidogrel dose of 150 mg once a day. Patients with slow metabolism were given tigrillo dose of 90 mg twice a day or aspirin dose of 100 mg once a day. The control group received 75 mg clopidogrel once a day. All patients enrolled in the groups were followed up for 3 months by outpatients or telephone. The incidence of vascular events and mRS scale scores were compared between the two groups. RESULTS: The incidence of vascular events in the individualized drug instruction group was significantly lower than that in the control group, and the incidence of mRS score(0-1) was significantly higher than that in the control group, with statistically significant differences (P<0.05). CONCLUSION: The individualized medication for patients with ischemic stroke by CYP2C19 gene detection can significantly reduce the incidence of adverse vascular events and improve the prognosis and living ability of patients.

Objective To compare the clinical efficacy of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with coronary heart disease and left ventricular systolic dysfunction. Methods A computer-based search in PubMed, The Cochrane Library and EMbase up to October 2017, together with reference screening, was performed to identify eligible clinical trials, cohort studies and case-control studies. The outcomes of this meta-analysis included all-cause mortality, myocardial infarction, revascularization and stroke, and the effect sizes for them were presented as relative risk (RR) with its 95% confidence intervals (CI). Results Fifteen cohort studies and 2 randomized controlled trials were finally included with a total of 11 985 patients, of whom 6 322 were in the CABG group and 5 663 in the PCI group. The result of meta-analysis showed that all-cause mortality was significantly lower in the CABG group than that in the PCI group (18.6% vs. 23.0%, RR=0.87, 95% CI 0.81 to 0.94, P<0.001). In addition, CABG was associated with a remarkably reduced risk of revascularization (RR=0.28, 95% CI 0.19 to 0.42, P<0.001) compared with PCI, with no significant difference in incidence of myocardial infarction (RR=0.78, 95% CI 0.47 to 1.32, P=0.36) and stroke (RR=1.28, 95% CI 0.89 to 1.86, P=0.18). Conclusion CABG is superior to PCI in the treatment for patients with coronary heart disease and left ventricular systolic dysfunction. Owing to the limited quality of included studies, additional large, randomized controlled trails are still required to confirm this finding.

OBJECTIVE To provide a reference for the safe use of drugs in patients with complex venous thromboembolism （VTE） and acute renal insufficiency. METHODS Clinical pharmacists participated in the management of anticoagulant therapy for a patient with complex VTE complicated with acute renal insufficiency， and evaluated the patient as high-risk thrombosis and bleeding based on their medical history， laboratory test results， etc.； combined with the complexity of thrombosis and renal insufficiency， clinical pharmacists suggested that enoxaparin sodium should be used in the acute stage of thrombosis （5 to 21 days after onset）， and then warfarin should be adopted for oral anticoagulation treatment. Because the patient’s anticoagulation was not up to the standard （the target range of the international normalized ratio was 2-3）， clinical pharmacists suggested increasing the warfarin dose， detecting the warfarin metabolism genotype， and adjusting the warfarin dose according to the genotype； at the same time， clinical pharmacists developed an anticoagulation monitoring plan to ensure the safety of anticoagulation treatment. RESULTS Doctors had adopted all the recommendations of clinical pharmacists. The patient did not experience adverse events such as bleeding or worsening of thromboembolism during anticoagulation in the hospital. When the anticoagulation met the standards， the patient was allowed to be discharged with medication. CONCLUSIONS By participating in the anticoagulation treatment management of patients with complex VTE and acute renal insufficiency， clinical pharmacists have assisted doctors in formulating personalized anticoagulation plans to promote the compliance with the anticoagulation treatment standard and ensure the safety and effectiveness of medication for patients.

Objective To investigate primarily the correlation between depression and prognosis in patients with coronary heart disease(CHD).Methods 246 CHD patients were divided into the depression group and non-depression group.The relation between depression and incidence of short term cardiovascular events was compared.Results The incidence of angina pectoris,ST-segment elevated myocardial infarction,non ST-segment elevated myocardial infarction,congestive heart failure,ventricular tarchycardia,ventricular fibrillation and sudden death in the near future were 75.6%,11.1%,17.8%,26.7%,12.2%,8.9% and 7.8% respectively.Depression was an independent predictive factor of all cardiovascular events.Conclusion CHD patients complicated by depression have a high incidence of cardiovascular events,and the depression is an independent predictive factor of all cardiovascular events.

OBJECTIVE: To investigate the molecular mechanisms underlying the effect of baicalin on prostate cancer (PCa) progression both in vivo and in vitro. METHODS: The in situ PCa stem cells (PCSCs)-injected xenograft tumor models were established in BALB/c nude mice. Tumor volume and weight were respectively checked after baicalin (100 mg/kg) treatment. Hematoxylin-eosin (HE) staining was used to observe the growth arrest and cell necrosis. mRNA expression levels of acetaldehyde dehydrogenase 1 (ALDH1), CD44, CD133 and Notch1 were determined by reverse transcription-polymerase chain reaction. Protein expression levels of ALDH1, CD44, CD133, Notch1, nuclear factor κB (NF-κB) P65 and NF-κB p-P65 were detected by Western blot. Expression and subcellular location of ALDH1, CD44, CD133, Notch1 and NF-κB p65 were detected by immunofluorescence analysis. In vitro, cell cycle distribution and cell apoptosis of PC3 PCSCs was assessed by flow cytometry after baicalin (125 µmol/L) treatment. The migration and invasion abilities of PCSCs were assessed using Transwell assays. Transmission electron microscopy scanning was utilized to observe the structure and autophagosome formation of baicalin-treated PCSCs. In addition, PCSCs were infected with lentiviruses expressing human Notch1. RESULTS: Compared with the control group, the tumor volume and weight were notably reduced in mice treated with 100 mg/kg baicalin (P<0.05 or P<0.01). Histopathological analysis showed that baicalin treatment significantly inhibited cell proliferation and promoted cell apoptosis. Furthermore, baicalin treatment reduced mRNA and protein expression levels of CD44, CD133, ALDH1, and Notch1 as well as the protein expression of NF-κB p-P65 in the xenograft tumor (P<0.01). In vitro, the cell proliferation of PCSCs was significantly attenuated after treatment with 125 µmol/L baicalin for 72 h (P<0.01). The cell migration and invasion rates were decreased following treatment with baicalin for 48 and 72 h (P<0.01). Baicalin notably induced cell apoptosis and seriously damaged the structure of PCSCs. The mRNA and protein expressions of CD133, CD44, ALDH1 and Notch1 in PCSCs were significantly downregulated following baicalin treatment (P<0.01). Importantly, the inhibitory effects of baicalin on PCa progression and stemness were reversed by Notch1 overexpression (P<0.05 or P<0.01). CONCLUSION Mechanistically, baicalin exhibited a potential therapeutic effect on PCa via inhibiting the Notch1/NF-κB signaling pathway and its mediated cancer stemness.

OBJECTIVE To provide reference for the management of antithrombotic therapy in thrombocytopenia patients with atrial fibrillation and atherosclerosis. METHODS The clinical pharmacist participated in the treatment of a thrombocytopenia patient with atrial fibrillation and atherosclerosis， and analyzed the causes of thrombocytopenia according to the patient’s medical history and laboratory examination results. At the same time， the risk of thrombosis-bleeding was evaluated according to the relevant guidelines， and the clinicians were assisted in formulating individual antithrombotic therapy plan and pharmaceutical care plan for the patient. The literature on antithrombotic therapy related to thrombocytopenia was collected and analyzed by retrieving CNKI. RESULTS Thrombocytopenia was considered as primary thrombocytopenia in this patient， and the main risk of bleeding was age ≥65 years old， bleeding tendency， and combined use of antithrombotic drugs. After the clinical pharmacist assessed the risk of thrombosis and bleeding， the clinician was recommended to give full dose of Bemiheparin sodium injection + Dronedarone hydrochloride tablets + Metoprolol succinate sustained-release tablets. In view of thrombocytopenia， the clinician gave Compound zaofan pill， Caffeic acid tablet and Sheng xuexiaoban capsule， but the patient developed diarrhea after the medication. The clinical pharmacist suggested stopping Sheng xuexiaoban capsule， and the clinician adopted the clinical pharmacist’s suggestion. When the patient was discharged from hospital， the clinical pharmacist suggested that the antithrombotic therapy plan for discharge was anticoagulation alone or selective anticoagulation. The clinician chose selective anticoagulation treatment considering that the patient’s current thrombocytopenia， urinary occult blood （+） and fecal occult blood were weakly positive， and ordered the patient to take Metoprolol succinate sustained-release tablets + Atorvastatin calcium tablets at discharge. Literature analysis showed that the causes of thrombocytopenia of patients with thromboembolism mainly included heparin induced-thrombocytopenia， immune thrombocytopenia， etc. All patients were improved after symptomatic treatment. CONCLUSIONS By participating in the management of antithrombotic therapy for the thrombocytopenia patient with atrial fibrillation and atherosclerosis， clinical pharmacists can help effectively control the patient’s condition and ensure the safety and effectiveness of drug use.

Objective To understand the prevalence and risk factors of Blastocystis hominis infection in inpatients in Jiangjin District, Chongqing City. Methods A cross-sectional study was conducted in a community hospital in Jiangjin District, Chongqing City, and the inpatients were surveyed by questionnaires. After obtaining the informed consent from the inpatients or legal guardians, the stool and blood samples were collected and examined by microscopy and PCR from April 17 to May 1, 2018. The univariate analysis and logistic regression analysis were used to analyze the risk factors of the B. hominis infection. Results A total of 198 hospitalized patients were investigated, and the infection rate of B. hominis was 10.61% (21/198), and the infection rate of the females (12.10%) was higher than that of the males (8.11%), but the difference was not statistically significant. The highest rate of infection was 19.23% in the age group of 10 to 20 years, followed by 17.74% in the age group of 60 years and above, and the lowest rate was 2.38% in the age group of 20 to 40 years. The difference in infection rates of B. hominis among the different age groups was statistically significant (P < 0.05). The infection rate of B. hominis in the people who used dry pail latrines was 33.30%, which was higher than that of the people who used water flush toilets (9.10%) (P < 0.05). The genotypes of B. hominis were ST1, ST3, ST6 and ST7, and ST6 and ST3 being the most predominant genotypes which accounted for 47.62% (10/21) and 38.10% (8/21) respectively, and among the infected males, the genotypes were only ST3 and ST6. The multiple logistic regression analysis showed that among the factors affecting B. hominis infection, only keeping pets was a risk factor [OR = 3.798, 95% CI (1.245, 11.581), P < 0.05]. Conclusion A high prevalence of B. hominis infection is found in the inpatients in Jiangjin District, Chongqing City, the predominant genotypes are ST6 and ST3, and keeping pets may be one of the main risk factors.

OBJECTIVES: To evaluate the response to cardiac resynchronization therapy (CRT) and the correlation between CRT and pulmonary artery hemodynamic parameters. METHODS: The patients with chronic heart failure indicator for CRT were enrolled. The left ventricular end-systolic volume (LVESV) was measured by echocardiography and New York Heart Association (NYHA) classification was evaluated between one week before and six months after CRT. Mean pulmonary artery pressure (mPAP), pulmonary artery systolic pressure (PASP) and pulmonary vascular resistance (PVR) were measured by right heart catheterization. Left ventricular reverse remodeling (LVRR) is defined as a decrease of 15% or more in LVESV at the 6th month after CRT; Clinical response is defined as a decrease of NYHA classification at or above grade 1 at the 6th month after CRT. Pulmonary hypertension (PH) was defined as mPAP≥25 mmHg. According to the response, patients were divided into 3 groups: group A (LVRR+clinical response), group B (no LVRR+clinical response) and group C (no LVRR+no clinical response). The changes of NYHA classification, echocardiographic and pulmonary hemodynamic parameters were observed in the 3 groups. The Kaplan-Meier survival curve was used to analyze the differences in all-cause mortality, combined end-point events of death or re-hospitalization due to heart failure among different groups. RESULTS: A total of 45 patients with CRT implantation [aged (63.27±9.55) years, 36 males] were included. The average follow-up period was (33.76±11.50) months. Thirty-one patients (68.89%) were in group A, 9 of whom with PH. Eight patients (17.78%) were in group B, 7 of whom with PH. Six patients were in group C, all with PH. Cardiac function including NYHA classification, echocardiographic and pulmonary hemodynamic parameters had been significantly improved in group A after CRT implantation (<0.05). In group B, NYHA classification and pulmonary hemodynamic parameters were decreased significantly (<0.05), but echocardiographic parameters did not change obviously (>0.05). There were no significant changes in NYHA classification, echocardiographic and pulmonary hemodynamic parameters in group C (>0.05). Compared with group C, group A and group B had lower all-cause mortality (=0.005) and lower incidence of composite endpoint events (=0.001). CONCLUSIONS Patients with LVRR and clinical response after CRT have a good prognosis. Patients with clinical response but without LVRR have a better prognosis than those without clinical response and LVRR, which may be related to the decrease of pulmonary hemodynamic parameters such as mPAP and TPG.

Objective To investigate the prevalence and risk factors of Blastocystis infections among primary school students in Jiangjin District, Chongqing City. Methods A cross-sectional questionnaire survey was conducted among students sampled from a primary school in Jiangjin District, Chongqing City on April, 2018, and their stool samples were collected for microscopic examinations, in vitro culture and PCR assays to analyze the prevalence of Blastocystis infections and subtype of the parasite. In addition, the risk factors of Blastocystis infections among primary school students were identified using univariate analysis and multivariate logistic regression analysis. Results A total of 466 primary students were surveyed, and the subjects had a mean age of (9.81±1.66) years and included 236 males (50.64%) and 230 females (49.36%). The prevalence of Blastocystis infections was 15.24% (71/466) among the study students, and there was no significance difference in the prevalence between male and fe- male students (16.52% vs. 13.91%; χ2 = 0.616, P = 0.433). In addition, there was a significant difference in the prevalence of Blastocystis infections among grade 1 (6.35%, 4/63), grade 2 (5.17%, 3/58), grade 3 (21.74%, 15/69), grade 4 (25.30%, 21/83), grade 5 (10.19%, 11/108) and grade 6 students (20.00%, 17/85) (χ2 = 15.410, P = 0.009). There were four Blastocystis subtypes characterized (ST1, ST3, ST6 and ST7), in which ST6 was the most common subtype (45.07%, 32/71), followed by ST3 (25.35%, 18/71). Multivariate logistic regression analysis revealed that minority ethnicity [odds ratio (OR) = 4.259, 95% confidential inter- val (CI) : (1.161, 15.621)] and low maternal education level (primary school and below) [OR = 9.038, 95% CI: (1.125, 72.642)] were identified as risk factors of Blastocystis infection among primary school students in Jiangjin District, Chongqing City. Conclusions There is a high prevalence of Blastocystis infections detected among primary school students in Jiangjin District, Chongqing City, and ST6 and ST3 are predominant subtypes. Minority ethnicity and low maternal education level (primary school and below) are risk factors for Blastocystis infections in primary school students.
