Objective To explore the anesthesia management experience in the interventional treatment of pediatric congenital heart diseases (CHD) percutaneously guided by transthoracic echocardiography (TTE) on a mobile operating platform. Methods From March to July 2023, a total of 13 patients from remote areas underwent interventional treatment for CHD on the mobile operating platform of Fuwai Yunnan Cardiovascular Hospital. Patients who received non-tracheal intubation general anesthesia were retrospectively included. Results Eight children who had difficulty cooperating with the surgery (due to young age, emotional tension, crying) received monitored anesthesia care with local anesthesia supplemented by sedative and analgesic drugs while maintaining spontaneous breathing under the monitoring and management of an anesthesiologist (i.e., non-tracheal intubation general anesthesia). Among them, there were 5 males and 3 females, with an age of (6.95±3.29) years and a body weight of (19.50±6.04) kg. Through transthoracic echocardiography, they were diagnosed with atrial septal defect (6 patients), residual shunt after patent ductus arteriosus ligation (1 patient), and severe pulmonary valve stenosis (1 patient). The surgery proceeded smoothly, with satisfactory anesthesia and surgical effects, complete analgesia, and satisfactory postoperative recovery. There was 1 patient of body movement and 1 patient of respiratory depression during the operation, and both patients completed the surgery successfully after treatment. All children had no serious surgery- and anesthesia-related complications. The anesthesia time was 40.5 (34.5, 47.5) min, the surgery time was 39.0 (33.0, 45.5) min, and the recovery time was 43.0 (28.0, 52.5) min Conclusion Interventional surgery for CHD guided by TTE at a mobile platform is a minimally invasive approach without radiation damage. Non-tracheal intubation general anesthesia with spontaneous breathing can be safely and effectively implemented in children who cannot cooperate.

Neural precursor cells-expressed developmentally down-regulated protein-8 (NEDD8) is one of the important members of the ubiquitin family, which plays an important role in maintaining cell stability, cell cycle regulation, signal transduction, transcription, and translation, DNA repair, and tumorigenesis through covalently bound substrates (also known as neddylation modification). In recent years, studies have found that the dysfunction of NEDD8 and its related enzymes is common in liver diseases, and is widely involved in the biological processes of hepatitis, liver fibrosis, proliferation, invasion, apoptosis and autophagy of liver cancer cells. This article focuses on the research progress of NEDD8 in liver diseases.

Objective Neonatal sepsis (NS) is one of the main causes of neonatal death.Immune therapy is an important way in the comprehensive treatment of NS.This study investigated several databases in order to find the clinical evidence for the immunological treatment of neonatal sepsis (NS),and to explore its clinical application value.Methods Systematic reviews and randomized (or quasi-randomized) controlled trials (RCT) for immunological treatment of NS in newborn infants were searched from the databases of MEDLINE,EMBASE and Cochrane Library.The relevant literatures were statistically analyzed.Results Six systematic reviews (including 37 RCTs) were found to be involved in the therapy,and the drugs included intravenous immunoglobulin (containing high level of IgM),antistaphylococcal immunoglobulins,neutrophile granulocyte,granulocyte colony-stimulating factor,granulocyte-macrophage colony-stimulating factor,pentoxifylline and glutamine.Pentoxifylline could decrease the mortality (Z =2.71,P =0.006 8),shorten the hospitalization (Z =2.01,P =0.044),and reduce the incidence rate of necrotizing enterocolitis (NEC) (Z =1.67,P =0.095) of the NS infants.No therapeutic effect was found for other drugs in the treatment of NS.Conclusions Current clinical evidence for the immunological treatment of NS indicates that only Pentoxifylline could decrease the mortality,reduce the incidence rate of NEC and shorten the hospitalization of infants with NS.However,current evidence is only a small scale sampling and lacks multicenter studies.Researchers are encouraged to undertake large scale and well-designed multicenter trials to confirm the effectiveness of the immunological treatment of NS.

Objective To investigate palmar hyperhidrosis (PH) and the effects on mental health in a military command.Methods 26 392 soldiers were enrolled in this study by stratified-cluster random sampling.Each was required to complete a self-administered questionnaire regarding PH.The soldiers were assessed with symptom checklist-90 (SCL-90) and the factor scores were compared with army norm and civilian norm.Results A total of 25680 subjects fulfilled the questionnaires,and the response rate was 97.3％.The prevalence of PH in the survey sample was 2.66％ and the mild,moderate,and severe PH were 1.49％,0.83％,and 0.34％,respectively.The total mean score of SCL-90 in soldiers with PH (1.72±0.54) was higher than those none PH soldiers (1.65±0.58),civilian norm (1.49±0.41) and military norm (1.63±0.30).Multiple regression analysis showed that age,level of education and severity of PH were important factors for mental health of soldiers with PH (P＜0.05).Conclusion PH is more common in the military,which affect the mental health.The health service departments should pay attention to the treatment and psychological intervention of PH.

Objective:　To compare the dynamic changes of int erleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF) in intermingled skin graft with those in other types of skin grafts in rats. 　　Methods:　A 10%-15% third-degree burn was created in 180 Spreg ue-Dawley (SD) rats. After removing the scar, skin grafts were performed on the open wounds immediately with autoskin (aus, n=54), allosk in (als, n=54) and intermingled skin (n=36). That is to say, in the intermingled skin graft, a big piece of alloskin (mals) was grafted first, and 3 days later, small pieces of autoskin (maus) wer e embedded in the alloskin. The rest 36 rats were taken as the controls. And the biological activities of IL-1, IL-6 and TNF in graft sheets in each group wer e detected after skin graft. 　　Results:　The levels of IL-1, IL-6 and TNF in the aus group de creased steadily after their initial elevations, whereas in the als group they i ncreased significantly and kept on the peak level in the later phases. In the in termingled group, there appeared a lowest IL-1 level in the mals and a highest one in the maus simultaneously at 7 (4) days (The number out of parenthesis is t he days after transplanting with alloskin sheets, and the number in parenthesis is the days after embedding autoskin sheets in the intermingled skin graft. Simi larly hereinafter.) after skin graft (P<0.01), and the high level in the maus abruptly decreased at 14 (11) days after skin graft. At exactly the same phase on day 7 (4), a prominent peaked IL-6 in the mals occurr ed. In the later phases, the levels of TNF remained relatively low both in the m als and in the maus. From day 7 (4) on, each cytokine fluctuation in the mals sy nchronized with that in the maus. The longer the post transplantation period las ted, the more the positive cytokine correlated between the mals and the maus. 　　Conclusions:　The low levels of IL-1 and TNF may be important f actors to lighten the intensity of local rejection in the intermingled skin graf t. The temporarily peaked IL-6 is both an inducer which induces the production of local IL-1 receptor antagonists and soluble TNF receptors and a signal which indicates a local enhancement of Th2 cells. The mild rejection process and th e synchronized cytokine level during the later phases suggest a possible chimeri sm between the mals and the maus.

More than 20 protein bands with molecular weights of 19—175 KD in 18 strains of Ureaplosma urealyticum were detected by SDS-PAGE and thin layer scanning analysis. The molecular weights of major proteins were between 32 KD and 140 KD. Among them, the percentages of 67, 78 and 140 KD proteins were similar in all strains, but those of 32, 43 and 94 KD proteins were greatly different. Thus, Ureaplasma urealyticum can be divided into two groups: group A including serovars 2,5,7,9,10,11,12, and local isolates C,D, E, F; group B including serovars 1,3,6,13,14, and local isolates A, B. The serovars of Ureaplasma urealyticum could not be distinguished by using SDS-PAGE alone.
