Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

Objective To design a wearable cardiopulmonary monitoring system and validate its performance through preliminary human trials.Methods The wearable cardiopulmonary monitoring system was composed of a data collector,a wearing vest and an information management platform.The data collector used an EFM32GG330 SCM as the main microcon-troller unit(MCU),which included a respiratory modulation module,an ECG modulation module,a body position modulation module,a wireless communication module(involving in a Bluetooth module and a Wi-Fi module),a storage module and a power management module.The wearable vest had a cardigan-type structure,and was equipped with ECG sensors and respiratory motion sensors at its inner side.The information management platform was developed with Client/Server(C/S)architecture and Java/JavaScript.The system developed was compared with Mindray's IPM10 Patient Monitor routinely used in hospitals through preliminary human trials to verify its effectiveness in monitoring human heart rate and respiratory rate.Results The system developed could continuously monitor the human heart rate and respiratory rate for a long time,and the monitoring results had high consistency with those of Mindray's IPM10 Patient Monitor.Conclusion The system can be used for medical monitoring of cardiopulmonary indicators during training or exercise,providing accurate physiological information for health management.[Chinese Medical Equipment Journal,2024,45(4):51-55]

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.

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 summarize and analyze the clinical phenotypes,hereditary features and treatment and follow-up strategies of different hereditary pheochromocytoma/paragangliomas(PCC/PGL)and related syndromes.Methods Forty-four clinically diagnosed PCC/PGL patients admitted in our hospital from January 2000 to August 2022 were enrolled,and the clinical data of them and their family members were collected.Second-generation sequencing was performed on 43 patients for genetic detection,and Sanger sequencing was applied to verify the mutation of the probands and family members.Results There were 15 patients diagnosed with hereditary PCC/PGL,including 7 cases of von Hippel-Lindau(VHL)syndrome,3 cases of multiple endocrine neoplasia type 2(MEN2),and 5 cases of familial paraganglioma syndrome.Seven VHL syndrome families were diagnosed as VHL2A(c.500G＞A),VHL2B(c.239G＞T and c.444_457del),and VHL2C(c.293A＞G)according to their clinical manifestations.All probands received surgical treatment,and 2 cases of recurrent PCC and the patients with multiple renal cancer also received targeted therapy with sunitinib.Three MEN2 families carried c.1901G＞C,c.1832G＞A,and c.1901G＞A missense mutations,respectively,and were diagnosed with MEN2A clinically.All of them underwent adrenalectomy and thyroidectomy,including one for preventive thyroidectomy.Among the 5 familial paraganglioma syndrome families,4 patients carried SDHB mutations(SDHB:c.343C＞T,c.541-2A＞G,c.575G＞A,c.268C＞T)and 1 patient carried an SDHD mutation(SDHD:c.337_340del).Sporadic retroperitoneal PGL were most common.Conclusion More than 1/3 of PCC/PGL patients carry germline gene mutations,showing obvious genotype-phenotype correlation.Genetic diagnosis technology plays an important guidance role for clinical precision treatment and follow-up,and genetic counseling.

OBJECTIVES: To compare the clinical effect on Bell's facial palsy in the acute stage between the staging comprehensive treatment with acupuncture-moxibustion and western medication. METHODS: Sixty patients with Bell's facial palsy in the acute stage were randomly divided into an observation group and a control group, with 30 cases in each one. The patients in the control group were administered orally with prednisone acetate tablets and methylcobalamin tablets until the 28th day of illness. In the observation group, the staging comprehensive treatment with acupuncture-moxibustion was adopted. On the affected side, Qianzheng (EX-HN 16), Yifeng (TE 17), Sibai (ST 2), Yangbai (GB 14), Jiache (ST 6), Dicang (ST 4) and Touwei (ST 8), etc. were stimulated. In the acute stage (Day 1 to 7 of illness), the routine acupuncture and the point-toward-point needle insertion were delivered, no any manipulation was exerted at acupoints, and the needles were retained for 30 min. In the subacute stage (Day 8 to 14 of illness), on the base of the treatment as the acute stage, the depth of needle insertion was adjusted at a part of acupoints and the even needling technique was operated by twisting needle. Besides, electroacupuncture (EA) was attached to Qianzheng (EX-HN 16) and Dicang (ST 4), with continuous wave of low intensity and high frequency, 100 Hz, for 20 min. In the recovery stage (Day 15 to 28 of illness), on the base of the treatment as the subacute stage, the heavy stimulation of acupuncture was given, in which, the sticking and lifting needle techniques were delivered after the needles were inserted from Sibai (ST 2) toward Dicang (ST 4), and from Dicang (ST 4) toward Jiache (ST 6), separately; warm needling was operated at Yifeng (TE 17), and EA changed to stimulate the acupoints with the intermittent wave of high intensity and low frequency, 2 Hz, for 30 min. Acupuncture-moxibustion was given once every other day until the end of the 28th day of illness. The level of House-Brackmann facial nerve function rating scale (H-B grade),the score of Sunnybrook facial nerve grading system (Sunnybrook), the score of facial disability index (FDI), the temperature difference in the infrared thermal imaging facial area and electromyogram (EMG) situation of the affected muscle group were observed before and after treatment in the two groups. Using musculoskeletal ultrasound,the facial nerve diameter was detected and the clinical effect was compared between the two groups. RESULTS: After treatment, the level of H-B grade, Sunnybrook score, the scores of physical function and social life function in FDI were improved when compared with those before treatment in the patients of either group (P<0.01, P<0.05), and the results of these evaluations in the observation group were better than those of the control group (P<0.05). After treatment, the temperature difference of the frontal area, the eye area, the zygomatic area and the mouth corner was declined in comparison with that before treatment in the two groups (P<0.05), and the temperature difference in each area in the observation group was lower than that of the control group (P<0.05).The root mean square (RMS) of the frontal muscle group, the zygomatic muscle group and the orbicularis muscle group on the affected side increased in comparison with that before treatment in the two groups (P<0.01), and RMS of the observation group was higher than that of the control group (P<0.05) after treatment. Before treatment, the diameter of the facial nerve on the affected side was larger than that on the healthy side (P<0.01), and after treatment, the diameter on the affected side was reduced when compared with that before treatment in the two groups (P<0.01); the diameter of the facial nerve on the affected side in the observation group was smaller than that of the control group (P<0.05), while, the diameter on the affected side was larger when compared with the healthy side in the control group (P<0.05). The total effective rate of the observation group was 93.3% (28/30), higher than that of the control group (83.3% [25/30], P<0.05). CONCLUSIONS The staging comprehensive treatment with acupuncture-moxibustion is clearly effective on Bell's facial palsy in the acute stage, which affirms the effectiveness of acupuncture-moxibustion for the acute stage of Bell's facial palsy in comparison with conventional western medication.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive dysfunction and behavioral impairment, and there is a lack of effective drugs to treat AD clinically. Existing medications for the treatment of AD, such as Tacrine, Donepezil, Rivastigmine, and Aducanumab, only serve to delay symptoms and but not cure disease. To add insult to injury, these medications are associated with very serious adverse effects. Therefore, it is urgent to explore effective therapeutic drugs for AD. Recently, studies have shown that a variety of enzyme inhibitors, such as cholinesterase inhibitors, monoamine oxidase (MAO)inhibitors, secretase inhibitors, can ameliorate cholinergic system dysfunction, Aβ production and deposition, Tau protein hyperphosphorylation, oxidative stress damage, and the decline of synaptic plasticity, thereby improving AD symptoms and cognitive function. Some plant extracts from natural sources, such as Umbelliferone, Aaptamine, Medha Plus, have the ability to inhibit cholinesterase activity and act to improve learning and cognition. Isochromanone derivatives incorporating the donepezil pharmacophore bind to the catalytic active site (CAS) and peripheral anionic site (PAS) sites of acetylcholinesterase (AChE), which can inhibit AChE activity and ameliorate cholinergic system disorders. A compound called Rosmarinic acid which is found in the Lamiaceae can inhibit monoamine oxidase, increase monoamine levels in the brain, and reduce Aβ deposition. Compounds obtained by hybridization of coumarin derivatives and hydroxypyridinones can inhibit MAO-B activity and attenuate oxidative stress damage. Quinoline derivatives which inhibit the activation of AChE and MAO-B can reduce Aβ burden and promote learning and memory of mice. The compound derived from the combination of propargyl and tacrine retains the inhibitory capacity of tacrine towards cholinesterase, and also inhibits the activity of MAO by binding to the FAD cofactor of monoamine oxidase. A series of hybrids, obtained by an amide linker of chromone in combine with the benzylpiperidine moieties of donepezil, have a favorable safety profile of both cholinesterase and monoamine oxidase inhibitory activity. Single domain antibodies (such as AAV-VHH) targeted the inhibition of BACE1 can reduce Aβ production and deposition as well as the levels of inflammatory cells, which ultimately improve synaptic plasticity. 3-O-trans-p-coumaroyl maslinic acid from the extract of Ligustrum lucidum can specifically inhibit the activity of γ-secretase, thereby rescuing the long-term potentiation and enhancing synaptic plasticity in APP/PS1 mice. Inhibiting γ-secretase activity which leads to the decline of inflammatory factors (such as IFN-γ, IL-8) not only directly improves the pathology of AD, but also reduces Aβ production. Melatonin reduces the transcriptional expression of GSK-3β mRNA, thereby decreasing the levels of GSK-3β and reducing the phosphorylation induced by GSK-3β. Hydrogen sulfide can inhibitGSK-3β activity via sulfhydration of the Cys218 site of GSK-3β, resulting in the suppression of Tau protein hyperphosphorylation, which ameliorate the motor deficits and cognitive impairment in mice with AD. This article reviews enzyme inhibitors and conformational optimization of enzyme inhibitors targeting the regulation of cholinesterase, monoamine oxidase, secretase, and GSK-3β. We are hoping to provide a comprehensive overview of drug development in the enzyme inhibitors, which may be useful in treating AD.

ObjectiveA growing body of research suggests a strong link between metabolic imbalance and Alzheimer’s disease (AD). In recent years, the development of metabolomics makes it possible to study the characteristic changes of peripheral metabolism in AD. Serum levels of tryptophan and tyrosine were associated with mild cognitive impairment (MCI) and AD. The purpose of this study is to further characterize tryptophan and tyrosine levels in MCI and AD. MethodsWe stratified 765 participants from the Alzheimer’s Disease Neuroimaging Initiative-1 (ADNI-1) cohort into cognitively normal (CN; n=207), stable mild cognitive impairment (sMCI; n=201), progressive mild cognitive impairment (pMCI; n=171), and dementia due to AD (n=186). Serum tryptophan and tyrosine were analyzed for diagnostic value of MCI and AD. To evaluate the relationships between serum tryptophan and tyrosine and cerebrospinal fluid (CSF) biomarkers, brain structure (magnetic resonance imaging, MRI), cerebral glucose metabolism (¹⁸F-fluorodeoxyglucose-positron emission tomography, FDG-PET), and cognitive declines, through different cognitive subgroups. ResultsSerum tryptophan was decreased in patients with AD, pMCI or sMCI compared with CN. Serum tyrosine was decreased in patients with AD or pMCI compared with CN. Serum tryptophan has diagnostic value for pMCI and AD. Serum tyrosine has diagnostic value for AD. ConclusionSerum tryptophan and tyrosine contribute to the early diagnosis of AD. The detection of tryptophan and tyrosine can contribute to the pathogenesis of AD. Serum tryptophan and tyrosine were not significantly associated with core AD markers, cognitive function, brain structure and brain metabolism, so serum tryptophan and tyrosine may not be good peripheral AD biomarkers.
