Objective:To investigate the efficacy of neuromuscular electrical stimulation (NMES) combined with limb rehabilitation therapy in improving limb function of patients with hemiplegia due to stroke.Methods:A randomized controlled study was conducted on 110 patients with hemiplegia due to stroke admitted to the 987 Hospital of the PLA Joint Logistic Support Force from January 2021 to January 2023. These patients were divided into a control group and an observation group, with 55 cases each, using a random number table method. The control group received conventional rehabilitation therapy, while the observation group received NMES combined with limb rehabilitation therapy. All patients were treated for 3 months. The Trunk Impairment Scale, Brunnstrom Motor Function Scale, Surface Electromyography, Brunel Balance Scale, Simple Gait Test Scale, and Modified Ashworth Scale were used to evaluate trunk control function, limb control function, neuromuscular disorders, balance control function (forward-backward inclination angle, left-right inclination angle), gait temporal-spatial parameters, symmetry parameters, and muscle tone recovery in both groups before and after treatment.Results:After treatment, the Total Impairment Scale and Brunnstrom scores for upper and lower limbs in the observation group were higher than those in the control group [(18.31 ± 1.61) vs. (14.38 ± 1.42), (3.78 ± 0.41) vs. (3.01 ± 0.63), (3.75 ± 0.42) vs. (3.28 ± 0.63), t = 13.58, 7.60, 4.60, all P < 0.05]. Additionally, the scores for tibialis anterior, fibularis brevis, fibularis longus, medial gastrocnemius, lateral gastrocnemius muscle control were higher in the observation group compared with the control group. The scores for Berg Balance Scale, forward-backward inclination angle, left-right inclination angle, step frequency, step length, step speed, and step width in the observation group were also superior to those in the control group. All differences were statistically significant ( t = 17.88, 20.15, 24.62, 19.53, 22.80, 3.31, 8.66, 7.88, 6.08, 4.21, 7.43, 3.35, all P < 0.05). Furthermore, the deviations in step length, the ratio of support on the affected side to the unaffected side, and the ratio of swing on the affected side to the unaffected side in the observation group were lower than those in the control group [(3.53 ± 2.55) vs. (5.35 ± 3.21), (1.11 ± 0.04) vs. (1.14 ± 0.03), (1.10 ± 0.06) vs. (1.24 ± 0.09), t = 3.29, 4.45, 9.60, all P < 0.05]. Additionally, the level of muscle tone recovery in the observation group was higher than that in the control group ( Z = 2.53, P = 0.011). Conclusions:In the treatment of hemiplegia due to stroke, NMES combined with limb rehabilitation therapy can effectively improve patients' trunk and limb control, enhance balance function, and greatly promote muscle strength recovery.

Objective:To construct the symptom network of patients after hepatectomy, analyze the core symptoms and bridge symptoms in the network, and provide evidence for symptom management of patients after hepatectomy.Methods:A cross-sectional study was conducted to select the patients after hepatectomy in the Second Affiliated Hospital of Zhejiang University from January to July 2024 by convenient sampling method. M.D. Anderson Sympotom Inventory and the Symptom Module Specific to Primary Liver Cancer were used to investigate the composition of symptoms. Symptom clusters were extracted by exploratory factor analysis, and simultaneous network layout was constructed by R language to describe the relationship between symptoms and analyze the central indicators.Results:A total of 228 questionnaires were distributed and 220 valid questionnaires were collected. There were 174 males and 46 females, aged (60.31 ± 10.69) years old. The four symptom groups were neuroaffective symptom group, gastrointestinal symptom group, fatigue-related symptom group and pain-related symptom group, and the cumulative variance contribution rate was 54.592%.In the concurrent symptom network analysis, distress was the core symptom of node centrality index, and the top 3 bridge symptoms were pain (r bs=2.40), decreased appetite (r bs=2.10) and nausea (r bs=2.00), the correlation stability coefficients of network strength centrality, compact centrality and expected influence values were 0.595, 0.595 and 0.673, the symptom group network was stable. Conclusions:Distress is the core symptom of patients after hepatectomy, and pain, decreased appetite and nausea are bridge symptoms. It is recommended that medical staff construct intervention programs based on core symptoms and bridge symptoms, implement precise symptom management, and improve the outcome of symptom management of patients.

BACKGROUND: In China, stroke burden remains severe as it is a major cause of mortality and disability. Detailed analyses across different subtypes will help optimize intervention strategies, enhance resource allocation efficiency, and ultimately reduce the overall disease burden. METHODS: We conducted a descriptive analysis of the incidence, prevalence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lived with disability (YLDs) of stroke and its subtypes using data (1990-2021) from the Global Burden of Disease (GBD) database. A Joinpoint regression model was applied to quantitatively analyze the indicators and calculate the annual percentage change (APC) and average annual percentage change (AAPC). We applied the Bayesian age-period-cohort (BAPC) model to project trends for 2022-2040. RESULTS: Incidence of stroke increased by 100.64% from 1990 to 2021, with ischemic stroke (IS) exhibiting the largest increase (201.13%) among all the subtypes, and the incidence being consistently higher in males than in females. The YLL/YLD ratio for stroke and its subtypes has decreased, with the YLL/YLD ratio falling from 20.13 to 9.48 in 1990-2021, indicating an increase in non-fatal burden. After adjusting for age, the age-standardized incidence rates (ASIRs) of stroke and its subtypes declined, except for IS. The age-standardized mortality rate (ASMR) for subarachnoid hemorrhage (SAH) decreased significantly (APC: -15.31%; 2000-2004), with the largest reduction in the age-standardized DALY rate (ASDR) also occurring during this period (APC: -14.22%). Furthermore, BAPC projections (2022-2040) indicate that stroke ASIRs in males will slightly decline but increase in females. Meanwhile, the ASIR of IS is expected to continue to rise. Overall, the ASMR and ASDR are projected to decline. CONCLUSIONS Although China has made some progress in stroke prevention and control, several challenges remain. Controlling IS must be prioritized, especially due to the high stroke burden among males.

Objective:To study the phenotypes and genotypes of neonatal nonketotic hyperglycinemia (NKH).Methods:A neonate with severe NKH admitted to our hospital was retrospectively analyzed. Using keywords 'glycine cleavage enzyme', 'glycine decarboxylase', 'nonketotic hyperglycinemia' and 'glycine encephalopathy' (both in Chinese and English), multiple medical databases were searched until December 31, 2022. The clinical phenotypes and genotypes of neonatal NKH were summarized.Results:For our case, the neonate was lethargy and had no appetite on the second day of life, followed by recurrent seizures and irregular breathing, requiring mechanical ventilation. She died at 3 weeks of age. Two compound heterozygous variants were found in GLDC gene from whole exome sequencing , one was c.848C>G(p.A283G) of maternal origin and one was c.1607G>A(p.R536Q) of paternal origin. The former was a novel mutation. A total of 54 cases (including this case) were collected. The main clinical manifestations included poor feeding, decreased muscle tone, hiccups, progressive lethargy, irregular breathing, apnea and neonatal seizures. 42 cases (77.8%) had GLDC gene mutations, 9 cases (16.7%) had AMT gene mutations, 2 cases (3.7%) had LIAS gene mutations and 1 case (1.9%) had GCSH gene mutations. Conclusions:Neurological manifestations are most common in neonatal NKH with wide clinical variations. GLDC gene mutations are the predominant pathogenic mutations.

Objective:To prepare a phase-change lipid nanoparticle modified by tumor homing membrane-penetrating peptide (tLyP-1) and carrying paclitaxel (PTX) engineered by metal polyphenol network (TA-Fe 3+ ), and evaluate the therapeutic effects of tumor targeting, ultrasound/photoacoustic imaging and photothermal combined chemotherapy in vitro. Methods:Phase-change lipid nanoparticles (t-P@TFP) with TA-Fe 3+ engineered PTX mediated by tLyP-1 were prepared by solvent replacement method, thin film hydration method and double emulsification method. Its detection and characterization, in vitro targeting ability, photothermal conversion ability, in vitro photoacoustic and ultrasonic imaging ability, CCK-8 method, cell live and death double staining method and flow cytometry method were used to detect the safety of nanoparticles and the killing effects of different nanoparticles on 4T1 cells. Results:t-P@TFP nanoparticles were successfully prepared. Transmission electron microscopy showed that the nanoparticles were spherical with uniform shape and size, with a particle size of (209.8±1.56)nm and a potential of (-25.9±1.36)mV. Laser confocal scanning microscopy showed that t-P@TFP nanoparticles could gather around 4T1 cells in a targeted manner. It had an efficient photothermal conversion effect, and nanoparticles could quickly become microbubbles after being irradiated by near-infrared laser, which enhanced the in vitro ultrasonic imaging effect; The photoacoustic signal of nanoparticles increased with the increase of concentration. CCK-8 method, double staining of living and dead cells and flow cytometry showed that t-P@TFP combined photothermal chemotherapy had the best anti-tumor effect. Conclusions:t-P@TFP nanoparticles are successfully prepared. The nanoparticles have good targeting ability for photoacoustic and ultrasonic imaging and have good photothermal effect, killing breast cancer cells, which is expected to realize the integration of diagnosis and treatment.
