This study predicts the quality markers(Q-markers) for the cough-relieving and phlegm-expelling effects of Kening Granules based on pharmacodynamics, plasma drug chemistry, network pharmacology, and pharmacokinetics. Strong ammonia solution spray and phenol red secretion assays were employed to evaluate the cough-relieving and phlegm-expelling effects of Kening Granules. Twentysix absorbed prototype components of Kening Granules were identified by ultra high performance liquid chromatography coupled with QExactive Plus quadrupole/Orbitrap high resolution mass spectrometry(UHPLC-Q-Exactive Plus Orbitrap HRMS). Through network pharmacology, 11 potential active components were screened out for the cough-relieving and phlegm-expelling effects of Kening Granules. The 11 components acted on 40 common targets such as IL6, TLR4, and STAT3, which mainly participated in PI3K/Akt, HIF-1, and EGFR signaling pathways. Pharmacokinetic quantitative analysis was performed for 7 prototype components. Three compounds including azelaic acid, caffeic acid, and vanillin were identified as Q-markers for the cough-relieving and phlegm-expelling effects of Kening Granules based on their effectiveness, transmissibility, and measurability. The results of this study are of great significance for clarifying the pharmacological substance basis, optimizing the quality standards, and promoting the clinical application of Kening Granules.

At present, effective antibiotics and comprehensive symptomatic/supportive treatment as early as possible are mainly used for the treatment of severe pertussis in clinical practice. However, some children with severe pertussis have unsatisfactory response to commonly used drugs and treatment measures in the intensive care unit and thus have a high risk of death. Studies have shown that certain treatment measures given in the early stage, such as exchange transfusion, may help reduce deaths, but there is still a lack of uniform implementation norms. How to determine the treatment regimen for severe pertussis and improve treatment ability remains a difficult issue in clinical practice. This article reviews the advances in the treatment of severe pertussis, in order to provide a reference for clinical treatment and research.

BACKGROUND: The proportion of recurrences after discharge among patients with coronavirus disease 2019 (COVID-19) was reported to be between 9.1% and 31.0%. Little is known about this issue, however, so we performed a meta-analysis to summarize the demographical, clinical, and laboratorial characteristics of non-recurrence and recurrence groups. METHODS: Comprehensive searches were conducted using eight electronic databases. Data regarding the demographic, clinical, and laboratorial characteristics of both recurrence and non-recurrence groups were extracted, and quantitative and qualitative analyses were conducted. RESULTS: Ten studies involving 2071 COVID-19 cases were included in this analysis. The proportion of recurrence cases involving patients with COVID-19 was 17.65% (between 12.38% and 25.16%) while older patients were more likely to experience recurrence (weighted mean difference (WMD)=1.67, range between 0.08 and 3.26). The time from discharge to recurrence was 13.38 d (between 12.08 and 14.69 d). Patients were categorized as having moderate severity (odds ratio (OR)=2.69, range between 1.30 and 5.58), while those with clinical symptoms including cough (OR=5.52, range between 3.18 and 9.60), sputum production (OR=5.10, range between 2.60 and 9.97), headache (OR=3.57, range between 1.36 and 9.35), and dizziness (OR=3.17, range between 1.12 and 8.96) were more likely to be associated with recurrence. Patients presenting with bilateral pulmonary infiltration and decreased leucocyte, platelet, and CD4 CONCLUSIONS The main factors associated with the recurrence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) after hospital discharge were older age, moderate severity, bilateral pulmonary infiltration, laboratory findings including decreased leucocytes, platelets, and CD4

Postinfectious glomerulonephritis (PIGN) is most commonly caused by Streptococcus pyogenes in children, but PIGN associated with other pathogens has been described in the literature. A previously healthy 6-year-old boy was admitted with complaints of cough, fever, and right chest pain. The patient was diagnosed with pneumococcal bacteremia and influenza A virus infection and treated with antibiotics and antiviral agent. During hospitalization, generalized edema, hematuria, proteinuria, and increased blood pressure were observed; therefore, we started administering diuretics. The boy was discharged with gross hematuria, and even microscopic hematuria disappeared 14 weeks after discharge. We report a case of PIGN associated with bacteremic pneumococcal pneumonia and influenza A virus infection in children. A urine test and blood pressure measurement should be considered for the early detection of PIGN in children with pneumococcal or influenza A virus infection when they present with nephritic symptoms.

BACKGROUND: Fentanyl-induced cough (FIC) has a reported incidence of 13–65% on induction of anesthesia. Incentive spirometry (IS) creates forceful inspiration, while stretching pulmonary receptors. We postulated that spirometry just before the fentanyl (F) bolus would decrease the incidence and severity of FIC. METHODS: This study enrolled 200 patients aged 18–60 years and with American Society of Anesthesiologists status I or II. The patients were allocated to two groups of 100 patients each depending on whether they received preoperative incentive spirometry before fentanyl administration. Patients in the F+IS group performed incentive spirometry 10 times just before an intravenous bolus of 3 µg/kg fentanyl in the operating room. The onset time and number of coughs after fentanyl injection were recorded as primary outcomes. Any significant changes in blood pressure, heart rate, or adverse effects of the drug were recorded as secondary outcomes. RESULTS: Patients in the F+IS group had a significantly lower incidence of FIC than in the F group (6% vs. 26%) (P < 0.05). The severity of cough in the F+IS group was also significantly lower than that in group F (mild, 5 vs. 17; moderate 1 vs. 7; severe, 0 vs. 2) (P < 0.05). The median onset time was comparable in both groups (9 s [range: 6–12 s] in both groups). CONCLUSIONS: Preoperative incentive spirometry significantly reduces the incidence and severity of FIC when performed just before fentanyl administration.

PURPOSE: During emergence from anesthesia for a craniotomy, maintenance of hemodynamic stability and prompt evaluation of neurological status is mandatory. The aim of this prospective, randomized, double-blind study was to compare the effects of dexmedetomidine and remifentanil on airway reflex and hemodynamic change in patients undergoing craniotomy. MATERIALS AND METHODS: Seventy-four patients undergoing clipping of unruptured cerebral aneurysm were recruited. In the dexmedetomidine group, patients were administered dexmedetomidine (0.5 µg/kg) for 5 minutes, while the patients of the remifentanil group were administered remifentanil with an effect site concentration of 1.5 ng/mL until endotracheal extubation. The incidence and severity of cough and hemodynamic variables were measured during the recovery period. Hemodynamic variables, respiration rate, and sedation scale were measured after extubation and in the post-anesthetic care unit (PACU). RESULTS: The incidence of grade 2 and 3 cough at the point of extubation was 62.5% in the dexmedetomidine group and 53.1% in the remifentanil group (p=0.39). Mean arterial pressure (p=0.01) at admission to the PACU and heart rate (p=0.04 and 0.01, respectively) at admission and at 10 minutes in the PACU were significantly lower in the dexmedetomidine group. Respiration rate was significantly lower in the remifentanil group at 2 minutes (p<0.01) and 5 minutes (p<0.01) after extubation. CONCLUSION: We concluded that a single bolus of dexmedetomidine (0.5 µg/kg) and remifentanil infusion have equal effectiveness in attenuating coughing and hemodynamic changes in patients undergoing cerebral aneurysm clipping; however, dexmedetomidine leads to better preservation of respiration.

In the present study, we examined the effect of pertussis toxin (PTX) administered centrally in a variety of stress-induced blood glucose level. Mice were exposed to stress after the pretreatment of PTX (0.05 or 0.1 µg) i.c.v. or i.t. once for 6 days. Blood glucose level was measured at 0, 30, 60 and 120 min after stress stimulation. The blood glucose level was increased in all stress groups. The blood glucose level reached at maximum level after 30 min of stress stimulation and returned to a normal level after 2 h of stress stimulation in restraint stress, physical, and emotional stress groups. The blood glucose level induced by cold-water swimming stress was gradually increased up to 1 h and returned to the normal level. The intracerebroventricular (i.c.v.) or intrathecal (i.t.) pretreatment with PTX, a Gi inhibitor, alone produced a hypoglycemia and almost abolished the elevation of the blood level induced by stress stimulation. The central pretreatment with PTX caused a reduction of plasma insulin level, whereas plasma corticosterone level was further up-regulated in all stress models. Our results suggest that the hyperglycemia produced by physical stress, emotional stress, restraint stress, and the cold-water swimming stress appear to be mediated by activation of centrally located PTX-sensitive G proteins. The reduction of blood glucose level by PTX appears to due to the reduction of plasma insulin level. The reduction of blood glucose level by PTX was accompanied by the reduction of plasma insulin level. Plasma corticosterone level up-regulation by PTX in stress models may be due to a blood glucose homeostatic mechanism.

OBJECTIVETo investigate the influence of sex on the cough-preventing effect of target-controlled infusion(TCI)of remifentanil during anesthetic emergence.

METHODSA total of 25 female(group F)and 25 male(group M)patients undergoing thyroidectomy were recruited in the current study. Anesthesia was maintained with sevoflurane and remifentanil TCI.At the end of the surgery,inhalational anesthetics were discontinued,and remifentanil TCI at an effect-site concentration(Ce)of 2.0 ng/ml was maintained during emergence until extubation. The cough score,blood pressure,and heart rate(HR)during peri-extubation period as well as the respiratory rate,calm score,and sore throat score after extubation were evaluated.

RESULTSDuring extubation,the proportion of patients with no cough or just a single cough was significantly higher in group F than in group M(88% vs. 64%,P=0.047). Mean arterial pressure(P=0.025,P=0.037)and HR(P=0.035)were significantly increased during extubation compared with preoperative levels in group M.

CONCLUSIONSSex may influence the cough-preventing effect of remifentanil TCI during anesthetic emergence. At a Ce of 2.0 ng/ml,remifentanil has better cough-preventing effect and more stable hemodynamic status in females than in males.

BACKGROUND: Desflurane has lower solubility and shows a more rapid induction and recovery than sevoflurane, although it often induces increased cardiovascular response, emergence delirium, and respiratory complications. The change of anesthetic agent from sevoflurane to desflurane after induction may provide a smooth induction and rapid emergence. The aim of this study was to evaluate the effect of changing sevoflurane to desflurane after induction on the cardiovascular response, emergence delirium, and recovery characteristics during pediatric strabismus surgery. METHODS: For the study, 135 children scheduled for strabismus surgery were randomly divided into three groups: the S group (n = 45) and D group (n = 45) received sevoflurane or desflurane, respectively, for induction and maintenance, while the C group (n = 45) received sevoflurane for induction and desflurane for maintenance. Cardiovascular responses, pediatric anesthesia emergence delirium (PAED) scale scores, post-anesthesia care unit (PACU) length of stay, and the incidence of postoperative complications were compared between groups. RESULTS: The blood pressure of the D group was significantly different from that of the S and C groups (P < 0.05). The time to extubation and first crying were significantly longer in the S group (P < 0.001). There were no significant differences in PAED score, PACU length of stay, and the incidence of postoperative complications, except for cough, among the three groups. CONCLUSIONS: The change of desflurane after sevoflurane induction in pediatric strabismus surgery provided rapid emergence compared with sevoflurane, and attenuated cardiovascular responses and lesser respiratory complications as compared to desflurane. The emergence delirium was not influenced by either inhalational anesthetic.
