BACKGROUND: Pulmonary hypertension (PH) is common in patients with idiopathic pulmonary fibrosis (IPF) and is associated with poor outcomes. This study was performed to determine the clinical efficacy of PH-specific therapeutic agents for IPF patients.METHODS: We performed a systematic review and meta-analysis using MEDLINE, EMBASE, and the Cochrane Central Register. We searched randomized controlled trials (RCTs) without language restriction until November 2018. The primary outcome was all-cause mortality to end of study.RESULTS: We analyzed 10 RCTs involving 2,124 patients, 1,274 of whom received PH-specific agents. In pooled estimates, the use of PH-specific agents was not significantly associated with reduced all-cause mortality to end of study compared with controls (hazard ratio, 0.99; 95% confidence interval [CI], 0.92, 1.06; P = 0.71; I² = 30%). When we performed subgroup analyses according to the type of PH-specific agent, sample size, age, forced vital capacity, diffusion lung capacity, and the extent of honeycombing, PH-specific agents also showed no significant association with a reduction in all-cause mortality. A small but significant improvement in quality of life, measured using the St. George Respiratory Questionnaire total score, was found in the PH-specific agent group (mean difference, −3.16 points; 95% CI, −5.34, −0.97; P = 0.005; I² = 0%). We found no significant changes from baseline in lung function, dyspnea, or exercise capacity. Serious adverse events were similar between the two groups.CONCLUSION: Although PH-specific agents provided small health-related quality-of-life benefits, our meta-analysis provides insufficient evidence to support their use in IPF patients.

Obesity is a major public health issue worldwide and is frequently associated with erectile dysfunction (ED). Both conditions may share an internal pathologic environment, also known as common soil. Their main pathophysiologic processes are oxidative stress, inflammation, and resultant insulin and leptin resistance. Moreover, the severity of ED is correlated with comorbid medical conditions, including obesity. Therefore, amelioration of these comorbidities may increase the efficacy of ED treatment with phosphodiesterase 5 inhibitors, the first-line medication for patients with ED. Although metformin was originally developed as an insulin sensitizer six decades ago, it has also been shown to improve leptin resistance. In addition, metformin has been reported to reduce oxidative stress, inflammatory response, and body weight, as well as improve ED, in animal and human studies. Moreover, administration of a combination of metformin and phosphodiesterase 5 inhibitors improves erectile function in patients with ED who have a poor response to sildenafil and are insulin resistant. Thus, concomitant treatment of metabolic derangements associated with obesity in patients with ED who are obese would improve the efficacy and reduce the refractory response to penile vasodilators. In this review, we discuss the connecting factors between obesity and ED and the possible combined treatment modalities.

OBJECTIVE: To explore the clinical therapeutic effect and mechanism of acupuncture on headache in the recovery phase of ischemic stroke. METHODS: A total of 97 patients with headache in the recovery phase of ischemic stroke were randomized into an acupuncture group (57 cases) and a western medication group (40 cases). In the western medication group, flunarizine hydrochloride capsule was taken orally 5 mg each time, once a day. In the acupuncture group, acupuncture was applied at Qiuxu (GB 40), Zulinqi (GB 41), Xuanli (GB 6), Shuaigu (GB 8), Fengchi (GB 20) and Baihui (GV 20) for migraine; Chongyang (ST 42), Neiting (ST 44), Jiexi (ST 41), Zusanli (ST 36), Hegu (LI 4), Cuanzhu (BL 2) and Baihui (GV 20) for forehead pain; Jinggu (BL 64), Kunlun (BL 60), Tianzhu (BL 10), Fengchi (GB 20), Baihui (GV 20) and Sishencong (EX-HN 1) for occipital headache; Taichong (LR 3), Yongquan (KI 1), Sanyinjiao (SP 6), Fengchi (GB 20), Baihui (GV 20) and Sishencong (EX-HN 1) for parietal headache. The needles were retained for 30 min each time, once a day and 5 times a week. Both of the two groups were given consecutive treatment for 14 days. The visual analogue scale (VAS) and the headache scores before and after treatment and the recurrence rate 1 month after treatment were observed to evaluate the therapeutic effect, before and after treatment, the contents of substance P (SP), dopamine (DA), serotonin (5-HT), alpha-endorphin (α-EP) and beta-endorphin (β-EP) in plasma were determined by ELISA in the two groups. RESULTS: Compared before treatment, the VAS scores, the headache scores and the contents of SP, DA and 5-HT in plasma were reduced and the contents ofα-EP andβ-EP in plasma were increased in the two groups (all <0.01). After treatment, the changes of the VAS score, the headache score and the contents of pain-related factors and endogenous opioid peptides in plasma in the acupuncture group were larger than the western medication group (all <0.05). The total effective rate in the acupuncture group was 84.2% (48/57), which was superior to 62.5% (25/40) in the western medication group, and the recurrence rate in the acupuncture group was lower than the western medication group (both <0.01). CONCLUSION The therapeutic effect of acupuncture on headache in the recovery phase of ischemic stroke is superior to flunarizine hydrochloride capsule, and the mechanism may relate to down-regulate the pain-related factors and up-regulate endogenous opioid peptides in plasma.

OBJECTIVE: To determine the effect of trimetazidine on cardiac function and exercise tolerance in primary hypertension patients with type 2 diabetic. METHODS: In this randomized, double-blind, placebo-controlled prospective study, 60 primary hypertensive patients with diabetic were equally assigned into two groups, patients received trimetazidine (20 mg, 3 times a day) or placebo for 1 year. Echocardiography, cardiopulmonary exercise testing were performed; and the plasma N terminal pro B type natriuretic peptide (NT-ProBNP), hr-CRP, TNF-α, angiotensin Ⅱ and endothelin concentration were determined before and after treatment. RESULTS: In trimetazidine group, the left ventricular mass index, the mitral flow velocity E wave to A wave ratio (E/A), the peak early diastolic velocity (V) to late diastolic velocity (V) ratio (V/V) and the peak systolic velocity (Vs) were significantly improved, the plasma NT-ProBNP level was significantly decreased, and the exercise time, metabolic equivalent, maximal oxygen uptake and anaerobic threshold were significantly increased (all <0.05); plasma concentration of hr-CRP, TNF-α, angiotensin Ⅱ and endothelin were significantly reduced after trimetazidine treatment, compared with baseline (all <0.05) and with placebo (all <0.05). There were no significant differences in any of above parameters after treatment in placebo group (all >0.05). No severe adverse reaction was observed in both groups. CONCLUSIONS For patients with both hypertension and diabetes, trimetazidine can improve cardiac function and increase exercise tolerance.

PURPOSE: To describe a patient who presented with central serous chorioretinopathy after 2 months of tadalafil administration without any other underlying disease or medication. CASE SUMMARY: A 49-year-old male patient was transferred from a local clinic with metamorphopsia and decreased visual acuity in the right eye. His visual acuity was 6/20 in the right eye and 18/20 in the left eye. The fundus examination showed a large serous detachment between the superior and inferior blood vessel arcades in the right retina. In his medical history, he used tadalafil three times a week for 2 months. His medication was then stopped, and a follow-up examination was scheduled. After 2 months, a fundus examination showed resolution of the subretinal fluid, and his corrected visual acuity recovered to 20/20. CONCLUSIONS: Tadalafil (Cialis®) is a phosphodiesterase (PDE)-5 inhibitor and predominantly prescribed for the treatment of erectile dysfunction. PDE–5 inhibitors may be potent vasodilators in the retina and choroid, and may induce choroidal vessel engorgement leading to leakage across the retinal pigment epithelium and accumulation of subretinal fluid in selected patients. When making a diagnosis as central serous chorioretinopathy, the physician should confirm the causative drugs that are easy to miss, by performing a thorough review of the patient's medical history and promptly terminating the causative drugs.

OBJECTIVETo study the pharmacokinetics of puerarin (PUE) in Gegen Qinlian Decoction (, GQD), and the effects of PUE dosage variations on the pharmacokinetics of baicalin (BAL) in mice.

METHODSGQD is composed of the concentrated granules of four Chinese herbs. Three dosages with different levels of PUE, including GQD, GQD co-administered with PUE, and GQD co-administration with two times the amount of PUE, were used to research the pharmacokinetics of PUE and BAL in mice. The indirect competitive enzyme-linked immunosorbent assay (icELISA) methods based on an anti PUE-monoclonal antibody (MAb)and BAL-MAb were employed to determine the concentration of PUE and BAL in mice blood.

RESULTSAfter the co-administration of GQD with PUE, the area under the curves (AUC) of PUE increased 2.8 times compared with GQD. At the dose of GQD co-administration at two times that of PUE, the (AUC) of PUE was almost equal to that of GQD co-administration of PUE, showing non-linear pharmacokinetics. The (AUC) of BAL showed a good dose-related increase of PUE (r=0.993) in the range from 100 to 300 mg/kg, indicating that PUE dramatically affects the absorption of BAL in mice. There was no significant difference in the other pharmacokinetic parameters, such as the first time of maximum concentration (T), the second T, or the mean residence time.

CONCLUSIONSThe icELISA methods were successfully applied to pharmacokinetic studies of PUE and BAL in GQD in mice. The dosage variability of PUE of the main ingredient in GQD affects its own pharmacokinetic characteristics and the absorption characteristics of BAL.

BACKGROUNDThe clinical significance of acute vasoreactivity testing (AVT) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) remains unclear. We analyzed changes in hemodynamics and oxygenation dynamics indices after AVT in patients with CTEPH using patients with pulmonary arterial hypertension (PAH) as controls.

METHODSWe analyzed retrospectively the results of AVT in 80 patients with PAH and 175 patients with CTEPH registered in the research database of Beijing Chao-Yang Hospital between October 2005 and August 2014. Demographic variables, cardiopulmonary indicators, and laboratory findings were compared in these two subgroups. A long-term follow-up was conducted in patients with CTEPH. Between-group comparisons were performed using the independent-sample t-test or the rank sum test, within-group comparisons were conducted using the paired t-test or the Wilcoxon signed-rank test, and count data were analyzed using the Chi-squared test. Survival was estimated using the Kaplan-Meier method and log-rank test.

RESULTSThe rates of positive response to AVT were similar in the CTEPH (25/175, 14.3%) and PAH (9/80, 11.3%) groups (P > 0.05). Factors significantly associated a positive response to AVT in the CTEPH group were level of N-terminal pro-brain natriuretic peptide (≤1131.000 ng/L), mean pulmonary arterial pressure (mPAP, ≤44.500 mmHg), pulmonary vascular resistance (PVR, ≤846.500 dyn·s-1·m-5), cardiac output (CO, ≥3.475 L/min), and mixed venous oxygen partial pressure (PvO2, ≥35.150 mmHg). Inhalation of iloprost resulted in similar changes in mean blood pressure, mPAP, PVR, systemic vascular resistance, CO, arterial oxygen saturation (SaO2), mixed venous oxygen saturation, partial pressure of oxygen in arterial blood (PaO2), PvO2, and intrapulmonary shunt (Qs/Qt) in the PAH and CTEPH groups (all P > 0.05). The survival time in patients with CTEPH with a negative response to AVT was somewhat shorter than that in AVT-responders although the difference was not statistically significant (χ2 =3.613, P = 0.057). The survival time of patients with CTEPH who received calcium channel blockers (CCBs) was longer than that in the group with only basic treatment and not shorter than that of patients who receiving targeted drugs or underwent pulmonary endarterectomy (PEA) although there was no significant difference between the four different treatment regimens (χ2 =3.069, P = 0.381).

CONCLUSIONSThe rates of positive response to AVT were similar in the CTEPH and PAH groups, and iloprost inhalation induced similar changes in hemodynamics and oxygenation dynamics indices. A positive response to AVT in the CTEPH group was significantly correlated with milder disease and better survival. Patients with CTEPH who cannot undergo PEA or receive targeted therapy but have a positive response to AVT might benefit from CCB treatment.

PURPOSE: Calcium channel blockers diltiazem and nitrate have been used as selective coronary vasodilators for patients with significant coronary artery spasm (CAS). However, no study has compared the efficacy of diltiazem alone versus diltiazem with nitrate for long-term clinical outcomes in patients with CAS. MATERIALS AND METHODS: A total of 2741 consecutive patients without significant coronary artery disease with positive CAS by acetylcholine (Ach) provocation test between November 2004 and May 2014 were enrolled. Significant CAS was defined as a narrowing of >70% by incremental intracoronary injection of 20, 50, and 100 µg of Ach into the left coronary artery. Patients were assigned to either the diltiazem group (n=842) or the dual group (diltiazem with nitrate, n=1899) at physician discretion. To adjust for potential confounders, a propensity score matching (PSM) analysis was performed using the logistic regression model. After PSM analysis, two well-balanced groups (811 pairs, n=1622, C-statistic=0.708) were generated. RESULTS: At 5 years, there were similar incidences in primary endpoints, including mortality, myocardial infarction, revascularization, and recurrent angina requiring repeat coronary angiography between the two groups. Diltiazem alone was not an independent predictor for major adverse cardiovascular events or recurrent angina requiring repeat coronary angiography. CONCLUSION: Despite the expected improvement of endothelial function and the relief of CAS, the combination of diltiazem and nitrate treatment was not superior to diltiazem alone in reducing mortality and cardiovascular events up to 5 years in patients with significant CAS.

PURPOSE: The aim of this study was to explore characteristics of and risk factors for accidental inpatient falls. METHODS: Participants were classified as fallers or non-fallers based on the fall history of inpatients in a tertiary hospital in Seoul between June 2014 and May 2015. Data on falls were obtained from the fall report forms and data on risk factors were obtained from the electronic nursing records. Characteristics of fallers and non-fallers were analyzed using descriptive statistics. Risk factors for falls were identified using univariate analyses and logistic regression analysis. RESULTS: Average length of stay prior to the fall was 21.52 days and average age of fallers was 61.37 years. Most falls occurred during the night shifts and in the bedroom and were due to sudden leg weakness during ambulation. It was found that gender, BMI, physical problems such elimination, gait, vision and hearing and medications such as sleeping pills, antiarrhythmics, vasodilators, and muscle relaxant were statistically significant factors affecting falls. CONCLUSION: The findings show that there are significant risk factors such as BMI and history of surgery which are not part of fall assessment tools. There are also items on fall assessment tools which are not found to be significant such as mental status, emotional unstability, dizziness, and impairment of urination. Therefore, these various risk factors should be examined in the fall risk assessments and these risk factors should be considered in the development of fall assessment tools.
