Objective:To observe any effects of repetitive high-frequency transcranial magnetic stimulation (rTMS) on the upper limb motor function of stroke survivors with right hemiplegia.Methods:Forty stroke survivors with right hemiplegia were divided at random into a high-frequency rTMS group and a sham stimulation group, each of 20. In addition to routine rehabilitation, the high-frequency rTMS group was given daily high-frequency rTMS 5d per week for 2 weeks, while the sham stimulation group was provided with sham rTMS. Before and after the treatment, both groups were evaluated using the Fugl-Meyer Upper Extremity motor function evaluation scale (FMA-UE), surface electromyography (sEMG), and electroencephalographic microstatus testing. Any adverse reactions in the course of the treatment were recorded.Results:After the treatment, the average FMA-UE scores of both groups had improved significantly, with the average of the high-frequency rTMS group significantly higher than the other group′s average. After the treatment the peak-to-peak sEMG value of the radial long extensor carpi radialis longus muscle in the high-frequency rTMS group was significantly higher than before the treatment and significantly higher than that of the other group. The temporal coverage of microstate B, the average duration and temporal coverage of microstate C, and the temporal coverage and frequency of occurrence of microstate D after treatment of both groups were also significantly improved. The mean duration of electroencephalographic (EEG) microstate A was negatively correlated with the FMA-UE scale scores ( r=-0.57) and its temporal coverage was positively correlated with the peak-to-peak sEMG value of the ulnar lateral wrist flexor. The mean duration of EEG microstate B was positively correlated with the peak-to-peak sEMG value of the triceps brachii and deltoid, and the mean duration of EEG microstate C was also positively correlated with the peak-to-peak sEMG value of the deltoid muscle. Conclusions:High-frequency rTMS can effectively improve the upper limb motor functioning of stroke survivors with right hemiparesis. After high-frequency rTMS, the functional network activity related to EEG microstate B increases significantly, while that related to microstates C and D decreases significantly.

The male patient,one day old,was admitted to the hospital due to hypoglycemia accompanied by apnea appearing six hours after birth.The patient had transient hypoglycemia early after birth,and acute heart failure suddenly occurred on the eighth day after birth.Laboratory tests showed significantly reduced levels of adrenocorticotropic hormone and cortisol,and pituitary magnetic resonance imaging was normal.Genetic testing results showed that the patient had probably pathogenic compound heterozygous mutations of the TBX19 gene(c.917-2A＞G+c.608C＞T),inherited respectively from the parents.The patient was conclusively diagnosed with congenital isolated adrenocorticotropic hormone deficiency caused by mutation of the TBX19 gene.Upon initiating hydrocortisone replacement therapy,cardiac function rapidly returned to normal.After being discharged,the patient continued with the hydrocortisone replacement therapy.By the 18-month follow-up,the patient was growing and developing well.In neonates,unexplained acute heart failure requires caution for possible endocrine hereditary metabolic diseases,and timely cortisol testing and genetic testing should be conducted.[Chinese Journal of Contemporary Pediatrics,2024,26(3):321-324,V]

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To compare the therapeutic effects of different inhaled medications on patients with frequent cough in chronic obstructive pulmonary disease (COPD), including changes in symptoms and acute exacerbation.Methods:This study was based on the RealDTC study, and the study subjects were stable COPD patients from the Department of Pulmonary and Critical Care Medicine, the Second Xiangya Hospital, Central South University from December 2016 to March 2023. The demographic characteristics, smoking status, history of biofuel exposure, history of acute exacerbation in the past year, lung function, COPD Assessment Test (CAT) score, modified British Medical Research Council Respiratory Difficulty Questionnaire (mMRC) score, and inhalation medication regimen of the patients were collected. Patients with frequent cough are defined as having a cough score of ≥2 in the first item of the CAT score. According to the type of inhaled medication, patients with frequent cough are divided into l long-acting muscarine anticholinergic (LAMA), long-acting β2 agonists (LABA)+ LAMA, inhaled corticosteroids (ICS)+ LABA, and ICS+ LABA+ LAMA groups. At the 6th month follow-up, CAT scores were collected and symptom control was evaluated, including minimum clinical improvement (MCID) (defined as a decrease of ≥2 points from baseline in CAT scores at the 6th month) and improvement in cough symptoms (defined as a decrease of ≥1 point from baseline in cough scores). During a one-year follow-up, the number of acute exacerbations was evaluated. The relationship between different inhaled medications and prognosis in patients with frequent cough in COPD was evaluated using multivariate logistic regression analysis.Results:A total of 653 patients with frequent cough in COPD were included, with a CAT score of (16.4±6.1) and a cough score of 3(2, 3). After 6 months of follow-up, 403 patients (61.7%) achieved MCID, and 394 patients (60.3%) had improved cough symptoms; During a one-year follow-up, 227 patients (34.8%) experienced acute exacerbation. After receiving inhalation medication treatment, the CAT scores and cough scores of four groups of patients with frequent cough, namely LAMA, LABA+ LAMA, ICS+ LABA, and ICS+ LABA+ LAMA, decreased compared to before treatment (all P<0.05). There was a statistically significant difference in the proportion of △CAT score, MCID, and acute exacerbation among the four groups of LAMA, LABA+ LAMA, ICS+ LABA, and ICS+ LABA+ LAMA (all P<0.05), while there was no statistically significant difference in the proportion of △cough score and cough score reduction ≥1 point (all P>0.05). The results of multivariate logistic regression analysis showed that compared with patients treated with LAMA or ICS+ LABA drugs, patients with frequent cough in COPD treated with LABA+ LAMA or ICS+ LABA+ LAMA drugs were more likely to achieve MCID and less likely to experience acute exacerbation (all P<0.05). Conclusions:Compared with LAMA or ICS+ LABA, patients with frequent cough in COPD who receive LABA+ LAMA or ICS+ LABA+ LAMA drug treatment are more likely to improve symptoms and have a lower risk of acute exacerbation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the effects of different concentrations of lidocaine infiltration and analgesia in pleural cavity after lung cancer surgery on rehabilitation of patients.Methods A total of 86 patients with lung cancer were selected and divided into the high concentration group(43 cases)and low concentration group(43 cases)by random number table method.Patients in the high concentration group received injection of 2.0%lidocaine hydrochloride in pleural cavity through the epidural catheter 1st day after surgery,and patients in the low concentration group received injection of 1.5%lidocaine hydrochloride in pleural cavity.In addition,patients in the two groups were treated with patient-controlled intravenous analgesia after surgery.The first time of getting out of bed,first time of exhaustion,first time of defecation and hospital stay after surgery of the two groups were compared.The visual analogue scale(VAS)scores 6 hours,12 hours,24 hours and 48 hours after surgery,the occurrence of agitation during the postoperative awakening period,and the number of analgesic pump compressions and the dosage of analgesic drugs within 24 hours after surgery were compared.The incidence of adverse drug reactions 24 hours after surgery were recorded and the quality of recovery of patients 24 hours after surgery was evaluated by 40-item quality of recovery score(QoR-40).Results The first time of getting out of bed,first time of exhaustion,first time of defecation and hospital stay after operation of patients in the high concentration group were shorter than those in the low concentration group(P<0.05).The VAS scores of the two groups 12 hours and 24 hours after surgery were higher than those 6 hours after surgery(P<0.05),the VAS scores 24 hours and 48 hours after surgery were lower than those 12 hours after surgery(P<0.05),and the VAS scores 48 hours after surgery were lower than those 24 hours after surgery(P<0.05).The VAS scores 6 hours,12 hours,24 hours,and 48 hours after surgery of patients in the high concentration group were lower than those in the low concentration group(P<0.05).The occurrence of agitation during the postoperative awakening period,and the number of analgesic pump compressions and the dosage of analgesic drugs within 24 hours after surgery for patients in the high concentration group were lower/less than those in the low concentration group(P<0.05).There was no significant difference in the total incidence of adverse drug reactions between the two groups(P>0.05).The total QoR-40 score of patients in the high concentration group were higher than those in the low concentration group(P<0.05).Conclusion The use of 2.0%lidocaine infiltration and analgesia in pleural cavity for patients after lung cancer surgery can reduce the agitation during the awakening period,alleviate the postoperative pain,improve the quality of postoperative recovery,and promote the postoperative recovery of the patients,with certain safety.

Objective To summarize the epidemiological and clinical features of infectious diseases of the central nervous system(CNS)by a single-center analysis.Methods A retrospective analysis was conducted on the data of 1247 cases of CNS infectious diseases diagnosed and treated in the First Medical Center of PLA General Hospital from 2001 to 2020.Results The data for this group of CNS infectious diseases by disease type in descending order of number of cases were viruses 743(59.6％),Mycobacterium tuberculosis 249(20.0％),other bacteria 150(12.0％),fungi 68(5.5％),parasites 18(1.4％),Treponema pallidum 18(1.4％)and rickettsia 1(0.1％).The number of cases increased by 177 cases(33.1％)in the latter 10 years compared to the previous 10 years(P<0.05).No significant difference in seasonal distribution pattern of data between disease types(P>0.05).Male to female ratio is 1.87︰1,mostly under 60 years of age.Viruses are more likely to infect students,most often at university/college level and above,farmers are overrepresented among bacteria and Mycobacterium tuberculosis,and more infections of Treponema pallidum in workers.CNS infectious diseases are characterized by fever,headache and signs of meningeal irritation,with the adductor nerve being the more commonly involved cranial nerve.Matagenomic next-generation sequencing improves clinical diagnostic capabilities.The median hospital days for CNS infectious diseases are 18.00(11.00,27.00)and median hospital costs are ￥29,500(￥16,000,￥59,200).The mortality rate from CNS infectious diseases is 1.6％.Conclusions The incidence of CNS infectious diseases is increasing last ten years,with complex clinical presentation,severe symptoms and poor prognosis.Early and accurate diagnosis and standardized clinical treatment can significantly reduce the morbidity and mortality rate and ease the burden of disease.

Background/Aims: Chronic hepatitis C (CHC) patients who failed antiviral therapy are at increased risk for hepatocellular carcinoma (HCC). This study assessed the potential role of metformin and statins, medications for diabetes mellitus (DM) and hyperlipidemia (HLP), in reducing HCC risk among these patients. Methods: We included CHC patients from the T-COACH study who failed antiviral therapy. We tracked the onset of HCC 1.5 years post-therapy by linking to Taiwan’s cancer registry data from 2003 to 2019. We accounted for death and liver transplantation as competing risks and employed Gray’s cumulative incidence and Cox subdistribution hazards models to analyze HCC development. Results: Out of 2,779 patients, 480 (17.3%) developed HCC post-therapy. DM patients not using metformin had a 51% increased risk of HCC compared to non-DM patients, while HLP patients on statins had a 50% reduced risk compared to those without HLP. The 5-year HCC incidence was significantly higher for metformin non-users (16.5%) versus non-DM patients (11.3%; adjusted sub-distribution hazard ratio [aSHR]=1.51; P=0.007) and metformin users (3.1%; aSHR=1.59; P=0.022). Statin use in HLP patients correlated with a lower HCC risk (3.8%) compared to non-HLP patients (12.5%; aSHR=0.50; P<0.001). Notably, the increased HCC risk associated with non-use of metformin was primarily seen in non-cirrhotic patients, whereas statins decreased HCC risk in both cirrhotic and non-cirrhotic patients. Conclusions Metformin and statins may have a chemopreventive effect against HCC in CHC patients who failed antiviral therapy. These results support the need for personalized preventive strategies in managing HCC risk.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.
