Objective To investigate the clinical efficacy and prognosis of lung transplantation in the treatment of cystic fibrosis (CF). Methods Clinical data of one patient with end-stage CF undergoing allogeneic bilateral lung transplantation were retrospectively analyzed. Clinical characteristics, diagnostic methods and treatment strategies of the CF recipient were summarized. Results The recipient had suffered from relevant symptoms since childhood including repeated cough and purulent sputum for 30 years, complicated with recurrent pulmonary infection combined with acute exacerbation, chronic sinusitis and extremely severe malnutrition. Prior to lung transplantation, the patient had to depend upon the invasive ventilator due to respiratory muscle weakness, and admitted to intensive care unit (ICU) for a long time. Imaging examination revealed multiple cystic columnar bronchiectasis accompanied with infection in bilateral lungs. The diagnosis of CF was further confirmed by sweat test and gene detection. The recipient underwent bilateral lung transplantation on August 17, 2017 and received rehabilitation treatment. The lung function was gradually restored to normal. The recipient had obtained the same quality of life to the healthy counterparts since the date of manuscript submission (over 2 years). Conclusions Lung transplantation is an efficacious treatment for end-stage CF, which can not only save patients' lives, but also significantly improve the quality of life of patients.

The objectives of this study were to prepare pitavastatin-loaded poly lactic-co-glycolic acid nanoparticles(PLGA), to characterize their pharmaceutical properties, to conduct in vitro drug-release from the nanoparticles, and to observe the effects on the proliferation of endothelial progenitor cells. Both pitavastatin-loaded PLGA and blank PLGA nanoparticles were prepared using emulsion-solvent diffusion method with PLGA being carrier materials. Morphology of the nanoparticles was observed by scanning electron microscopy(SEM), and particle size was analyzed by laser nanometer particle size analyzer. The drug loading and encapsulation efficiency were assayed using high-performance liquid phase. Impact of blank and pitavastatin-loaded nanoparticles on the viability of endothelial progenitor cells was investigated by CCK8 method. Pitavastatin-loaded PLGA nanoparticles exhibited the structure with spherical shape, smooth surface and average diameter of(230. 1±45)nm. The drug loading capacity and encapsulation efficiency were(10. 00±1. 83)% and(35. 54±5. 40)%, respectively. In vitro sustained-release of pitavastatin from the nanoparticles was found. The blank PLGA nanoparticles had no effect on the viability of the endothelial progenitor cells in different concentrations. Compared with pitavastatin group, pitavastatin-loaded nanoparticles(0. 01 μmol/L, 0. 1 μmol/L)had more effects on the proliferation of endothelial progenitor cells. In conclusion, emulsion-solvent diffusion method is applicable in preparation of pitavastatin-loaded PLGA nanoparticles with good shape and sustained-release of interest. Pitavastatin-loaded nanoparticles could significantly improve proliferation of the endothelial progenitor cells.

Objective To illustrate the semiological characteristics of the three sub-types within the broad bilateral asymmetric tonic seizures (BATS),summarize their predictive values on lateralization and localization of seizure onset zone (SOZ),and analyze the difference between BATS and asymmetrical tonic limb posturing (ATLP).Methods A retrospective review of 385 patients who underwent stereotactic electrode implantation in the Sanbo Brain Hospital,Capital Medical University from September 2011 to May 2018 was performed.As long as there was a clinical epileptic seizure in the presence of BATS or ATLP,the patients were classified into the corresponding groups.Postoperative prognosis was assessed using Engel's grading criteria for a follow-up of no less than six months.Seizure descriptions were based on the classification of epileptic seizures introduced by Lüiders,which used arrows to connect the symptoms in chronological order.Results There was no statistically significant difference between the classic BATS and bilateral proximal tonic seizure in terms of whether it could be an independent seizure,as the onset and end of the seizure,with version and generalized tonic-clonic seizure (P＞0.05).Compared with the ATLP,except for whether it could be an independent seizure (P=1.000) and onset before versive seizure (P=0.068),the BATS showed significantly different semiological features (P＜0.05).The classic BATS and secondary motor area epilepsy had a 100.0％ predictive accuracy on the lateralization of SOZ.In the patients with broad BATS,the SOZ distribution was more extensive,but it was rare in the orbitofrontal gyrus,frontal pole and mesial temporal lobe.Compared with the bilateral proximal tonic seizures from the other regions,those originated from supplementary somatosensory motor area and its adjacent areas were rare and showed no statistically significant difference (0/8 vs 40.0％ (18/45),x2=3.226,P=0.072) but a low trend.The predictive value of BATS on lateralization of SOZ was higher than that of ATLP (84.9％ (45/53) vs 57.1％ (24/42),x2=9.086,P=0.003),and BATS was less originated from temporal lobe than ATLP (3.8％ (2/53) vs 23.8％ (10/42),x2=8.523,P=0.004).Conclusion Different from ATLP,the broad BATS are characterized by tonic proximal upper limb posturing,and have a higher predictive value on lateralization and localization of SOZ.

Objective:To explore the relative concentration changes of oxygenated hemoglobin (Oxy Hb) in the prefrontal cortex (PFC) and brain region activation during emotional face recognition tasks in women with perimenopausal depression.Methods:From February to April 2023, forty perimenopausal women were recruited, including 20 women with perimenopausal depression (experimental group) and 20 women with non-perimenopausal depression (control group). All participants were evaluated by the modified Kupperman score, 24-item Hamilton depression scale (HAMD-24), and patient health questionnaire (PHQ-9). Functional near-infrared spectroscopy (fNIRS) equipment was used to measure the relative concentration of Oxy-Hb in the PFC in two groups under the emotional face recognition task. Statistical analysis was performed by SPSS 26.0 software. Data were analyzed by a t-test, rank sum test, and Pearson correlation. Results:There were statistically significant differences in the results of the modified Kupperman score((23.20±3.66), (18.10±1.28)), HAMD-24((15.95±5.47), (3.35±1.84)), and PHQ-9(7.00(5.00, 10.75), 1.50(1.00, 3.00)) scales between the the experimental group and control group ( P<0.05). There was a positive correlation between the modified Kupperman score and the HAMD-24 score in the experimental group ( r=0.685, P=0.01). The reaction time of the experimental group in identifying negative and neutral emotional faces was statistically significant compared to the control group( t=4.01, 4.80, both P<0.05). Compared with identifying neutral emotions, PFC activation was stronger in the experimental group and control group when identifying negative emotions ( P<0.05). The PFC activation in the experimental group was stronger than that in the control group when identifying negative emotions ( P<0.05). There was no statistically significant difference in the activation level between the two groups when identifying neutral emotions ( P>0.05). Conclusion:Women with perimenopausal depression exhibit specificity in emotional processing, with increased PFC activation when identifying negative emotions, impaired emotional processing function of PFC, and dysfunction of aerobic metabolism.

Acute kidney injury (AKI) is one of the common early complications after lung transplantation, which not only increases the short-term and long-term fatality of lung transplant recipients, but also significantly increases the incidence of long-term chronic renal insufficiency after surgery. In recent years, early AKI after lung transplantation has attracted high attention along with the rapid development of lung transplantation in China. In this article, research progresses on diagnosis, incidence, risk factors, prevention and treatment of early AKI after lung transplantation around the globe were reviewed, aiming to better identify the risk factors and poor prognosis of early AKI after lung transplantation, and provide theoretical and practical guidance for early clinical interventions.

Background and Objectives: This study investigated the relative incidence of contrast induced nephropathy (CIN) and long-term outcomes between iso-osmolar contrast media (IOCM) and low-osmolar contrast media (LOCM) undergoing elective percutaneous coronary intervention (PCI). Methods: A total of 9,431 patients receiving elective PCI were enrolled in the cohort. The patients were divided into IOCM group and LOCM group. Propensity score matching (PSM) was applied to minimize the selection bias between groups. Results: The multivariate analysis showed that the use of IOCM compared with LOCM did not affect the CIN incidence (odds ratio [OR], 0.912; 95% confidence interval [CI], 0.576–1.446; p=0.696). After PSM, the incidence of CIN was 1.5% and 4.0% in IOCM group (n=979) and LOCM group (n=979), respectively, p=0.001. IOCM significantly reduced the incidence of CIN compared with LOCM (OR, 0.393; 95% CI, 0.214–0.722; p=0.003). After 2 years of follow-up, the all-cause mortality was higher in IOCM group than LOCM group (2.1% vs. 0.9%, p<0.001). Cox regression analysis showed IOCM was not independent risk factor of 2-years all-cause mortality (OR, 0.849; 95% CI, 0.510–1.412; p=0.528). After PSM, the difference of all-cause death between groups disappeared (1.7% vs. 1.9%, p=0.739). Cox regression analysis showed that the use of IOCM compared with LOCM did not affect the incidence of 2-year all-cause mortality (OR, 1.037; 95% CI, 0.534–2.014; p=0.915). Conclusions Compared with LOCM, IOCM significantly reduced the incidence of CIN after elective PCI, but had no significant effect on 2-year all-cause mortality.
