Recommendations for the Management of Patients with Benign Prostatic Hyperplasia in the Context of the COVID-19 Pandemic: A Retrospective Study of 314 Cases

Aim. Through investigation and analysis of the course management of 314 patients with benign prostatic hyperplasia (BPH) during the COVID-19 pandemic, we expected to offer effective recommendations for the management of patients with BPH against the background of the COVID-19 pandemic. Methods. We implemented telephone follow-ups of 314 patients with BPH who were diagnosed at the Urology Clinic of Xiangya Hospital of Central South University before January 24, 2020, and who were admitted to the hospital for reexamination after the epidemic was controlled in China, and we conducted research and analysis of their disease management during the COVID-19 pandemic. Results. In the follow-up, we found 245 patients (79.3%) over 60 years of age and 187 patients (60.5%) with underlying disease. There were 47 patients (15.2%) who returned for consultation during the COVID-19 pandemic, and of these, 18 were admitted to the hospital for follow-up consultation, and 29 patients underwent consultation via the internet or telephone. Eleven patients underwent surgery during the pandemic, and of these, three experienced emergency surgery. We encountered 65 patients (24.4%) who self-administered medications irregularly and 54 patients (20.3%) who self-medicated and adjusted the dosage and drug types themselves. There were 302 patients (97.7%) who wished to be reexamined during the COVID-19 pandemic. In terms of treatment, the proportion of patients “awaiting observation” declined from 13.9% to 4.4%, and the proportion of patients “awaiting surgery” increased from 4.9% to 16.4%. Using the International Prostate Symptom Score (IPSS) scale, the percentage of patients with moderate-to-severe symptoms increased from 79.9% to 90.1%, and the proportion with a rose from 82.5% to 88.9%. The proportions of patients exhibiting storage, voiding, and postmicturition symptoms in lower urinary tract symptoms (LUTS) increased from 77.3%, 21.7%, and 18.8% to 91.9%, 27.5%, and 25.5%, respectively; those manifesting hematuria and urinary retention increased from 0.9% and 0.6% to 2.3% and 1.7%, respectively; those with a rose from 10.0% to 15.1%; patients with a increased from 82.5% to 92.3%, and the proportion with a increased from 8.7% to 15.4%; the individuals with a prostate increased from 94.1% to 97.0%; the percentage of men with a bladder residual urine was augmented from 81.6% to 89.3%, and patients with prostate nodules on physical examination were elevated from 1.0% to 1.7%. We uncovered no prostate cancer in patients, and the proportion of patients administered the combination drug increased from 78.9% to 91.2%. Compared with patients receiving online or telephone consultations, patients undergoing reexamination at the hospital were better controlled. When we conducted a survey of whether patients chose to go to a public or private hospital for follow-up, we found that 46.6% of the patients chose to go to a private medical institution. Conclusions. COVID-19 greatly affected the treatment of patients with BPH. When conditions permit, we recommend that patients first consider going to the hospital for evaluation; however, when this is not possible, medical institutions should provide telephone or online consultation for patients with BPH. Surgical treatment should also be arranged for those in need as soon as possible to avoid delaying the patient’s treatment.

Is Femoral Nerve Block Superior to Fascia Iliac Block in Hip Surgery? Meta-Analysis of Randomized Controlled Trials

Background. Femoral nerve block (FNB) and fascia iliac compartment block (FICB) are alternative methods of pain relief during hip surgery. Nevertheless, the effectiveness and safety of FNB compared with FICB are yet to be fully determined. Methods. Electronic databases were systematically searched. Only randomized controlled trials (RCTs) on hip surgery were included. Postoperatively, the pain scores at different time points, narcotic requirements in 24 h, mean arterial pressure, spinal anesthesia (SA) time, patient satisfaction, and adverse effect rates between the two groups were extracted throughout the study. Results. Fourteen RCTs including 1179 patients were included. Compared to the FICB, FNB decreased the VAS scores postoperatively at 24 h at rest () and the incidence rate of some side effects (nausea, vomiting, and sedation) (). However, compared to the FICB, no significant difference was found in the FNB regarding the VAS scores postoperatively at any of the other time points (2 min, 20 min, 2 h, 24 h at movement, 48 h at rest, and 48 h at movement). Patients in both groups had similar narcotic needs after 24 h, mean arterial pressure, SA time, and patient satisfaction (). Conclusions. FNB has more advantages in reducing VAS scores postoperatively at 24 h at rest and the odds of some adverse effects. A better quality RCT is needed to properly compare FNB with FICB.

Jinlida Granules Reduce Obesity in db/db Mice by Activating Beige Adipocytes

Recent studies indicate existence of beige adipocytes in adults. Upon activation, beige adipocytes burn energy for thermogenesis and contribute to regulation of energy balance. In this study, we have analyzed whether Jinlida granules (JLD) could activate beige adipocytes. JLD suspended in 0.5% carboxymethyl cellulose (CMC) was gavage fed to db/db mice at a daily dose of 3.8 g/kg. After 10 weeks, body weight, biochemical, and histological analyses were performed. In situ hybridization, immunofluorescence, and western blotting were conducted to test beige adipocyte activation in mice. X9 cells were induced with induction medium and maintenance medium containing 400 μg/mL of JLD. After completion of induction, cells were analyzed by Nile red staining, time polymerase chain reaction (PCR), western blotting, and immunofluorescence to understand the effect of JLD on the activation of beige adipocytes. A molecular docking method was used to preliminarily identify compounds in JLD, which hold the potential activation effect on uncoupling protein 1 (UCP1). JLD treatment significantly improved obesity in db/db mice. Biochemical results showed that JLD reduced blood glucose (GLU), triglyceride (TG), and low-density lipoprotein cholesterol (LDL) levels as well as liver aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels in mice. Hematoxylin and eosin staining (H&E) showed that JLD reduced hepatocyte ballooning changes in the liver. Immunofluorescence showed that JLD increased the expression of the thermogenic protein, UCP1, in the beige adipose tissue of mice. JLD also increased the expression of UCP1 and inhibited the expression of miR-27a in X9 cells. Molecular docking results showed that epmedin B, epmedin C, icariin, puerarin, and salvianolic acid B had potential activation effects on UCP1. The results suggest that JLD may activate beige adipocytes by inhibiting miR-27a expression, thereby promoting thermogenesis in beige adipocytes. This study provides a new pharmacological basis for the clinical use of JLD.

Effects of Etanercept on TNF-α Inhibition in Rats with Adenine-Induced Chronic Kidney Disease

Introduction. Chronic kidney disease (CKD) constitutes a chronic inflammatory state associated with an increase in inflammatory mediators and profibrotic molecules such as tumor necrosis factor-α (TNF-α). Etanercept (ETA) is a TNF inhibitor widely used in treatment of autoimmune inflammatory diseases. However, the effects of TNF-α inhibition in the establishment of CKD have not been fully elucidated. We evaluate the effects of TNF inhibition by ETA in adenine- (Ad-) induced CKD in rats. Methods. Rats were divided into three groups: control, renal injury model, and model plus ETA (2 mg/kg, 3 times per week (w); sc). Renal injury was induced by Ad administration (100 mg/kg, daily for 2 or 4 w; orogastric). Serum TNF-α levels and biochemical parameters for renal function were evaluated. Histopathological changes in the kidney were assessed using H&E and Masson’s trichrome staining and also immunostaining for tubular cells. Results. Ad administration produced a renal functional decline, tubular atrophy, interstitial inflammation, and fibrosis for 2 w, followed by renal anemia, several renal dysfunctions, tubular atrophy, and fibrosis at 4 w. A significant increase in serum TNF-α levels was observed from 2 w of Ad administration and remained elevated up to 4 w. Treatment with ETA partially reduced kidney damage but was very effective to blocking serum TNF-α. Conclusion. Although inhibition of TNF by ETA was very effective in reducing serum TNF-α, this strategy was partially effective in preventing Ad-induced CKD.

Histopathological Investigations and Molecular Confirmation Reveal Mycobacterium bovis in One-Horned Rhinoceros (Rhinoceros unicorns)

Mycobacterium bovis causes tuberculosis in dairy and wild animals. Presence of tuberculosis in animals poses a threat not only to their herd mates but also for public. No reports are available about the clinical, pathological, and molecular investigation of naturally occurring tuberculosis (TB) due to M. bovis in one-horned rhinoceros. One-horned female rhinoceros (Rhinoceros unicorns) at the age of 41 years died in a public park in Pakistan. Postmortem and other investigations were carried out to know the cause of death. The present study describes necropsy, histopathology, and molecular-based confirmation of TB in a captive female rhinoceros that died of this infection. Clinically, the rhinoceros showed nonspecific clinical signs including anorexia, lethargy, dyspnoea, coughing, and sudden death. At necropsy, the trachea exhibited mild congestion and contained catarrhal exudate at the bronchial bifurcation. Macroscopic examination revealed characteristic tubercles on all parenchymatous organs. The lungs showed consolidation, grey hepatization, and contained granulomatous lesions packed with cheesy exudate. Histopathological examination showed severe pneumonic changes in the form of granulomatous inflammation consisting of lymphocytes, multinucleated giant cells, caseous materials, and mineralized foci surrounded by a fibrous capsule. PCR amplicon of 500 bp confirmed the presence of M. bovis in multiple hepatic and pulmonary tissue samples, as well as in uterine exudates. It was concluded that the presence of tuberculosis in rhinoceros may pose potential transmission risk to other animals and the application of practical tools to determine TB status in the rhinoceros is crucial.

Clinical Effect of Nicorandil Combined with Aspirin in the Treatment of Myocardial Ischemia

Objective. To investigate the clinical effect of nicorandil combined with aspirin in the treatment of myocardial ischemia. Methods. A total of 104 patients with myocardial ischemia were admitted to our hospital from June 2019 to August 2020. These patients were selected as the research objects and randomly divided into two groups: the control group and the observation group. The control group was given asilin, and the observation group was given nicorandil tablets based on the control group. Both groups were given continuous treatment for 3 months. The curative effect, cardiac function indexes, dynamic electrocardiogram, and the occurrence of adverse reactions were observed in the two groups. Results. The total effective rate of the observation group was 96.15% (50/52), which was higher than that of the control group (61.54%, 32/52), and the difference was statistically significant (). After treatment, left ventricular ejection fraction (LVEF) and peak early/late diastolic flow velocity (E/A) were increased (), while peak early diastolic flow velocity to peak mitral annular root movement velocity (E/Ea) was decreased (). After treatment, LVEF and E/A in the observation group were higher than those in the control group, while E/Ea was lower than that in the control group (). The frequency, duration of ST segment, and a total load of myocardial ischemia in the ST segment within 24 h after treatment were decreased compared with those before treatment (). The frequency and duration of ST segment decreased, and the total load of myocardial ischemia in the observation group was lower than those in the control group within 24 h after treatment (). After treatment, the total occurrence of adverse reactions in the observation group was lower than that in the control group (). Conclusion. Nicorandil combined with aspirin in the treatment of patients with myocardial ischemia has a significant effect, which can effectively improve the electrocardiogram and cardiac function indicators of patients and reduce the incidence of adverse reactions and is worthy of clinical application.
