The accurate and timely detection of biochemical coagulation indicators is pivotal in pulmonary and critical care medicine. Despite their reliability, traditional laboratories often lag in terms of rapid diagnosis. Point-of-care testing (POCT) has emerged as a promising alternative, which is awaiting rigorous validation. We assessed 226 samples from patients at the First Affiliated Hospital of Guangzhou Medical University using a Beckman Coulter AU5821 and a PUSHKANG POCT Biochemistry Analyzer MS100. Furthermore, 350 samples were evaluated with a Stago coagulation analyzer STAR MAX and a PUSHKANG POCT Coagulation Analyzer MC100. Metrics included thirteen biochemical indexes, such as albumin, and five coagulation indices, such as prothrombin time. Comparisons were drawn against the PUSHKANG POCT analyzer. Bland-Altman plots (MS100: 0.8206‒0.9995; MC100: 0.8318‒0.9911) evinced significant consistency between methodologies. Spearman correlation pinpointed a potent linear association between conventional devices and the PUSHKANG POCT analyzer, further underscored by a robust correlation coefficient (MS100: 0.713‒0.949; MC100: 0.593‒0.950). The PUSHKANG POCT was validated as a dependable tool for serum and whole blood biochemical and coagulation diagnostics. This emphasizes its prospective clinical efficacy, offering clinicians a swift diagnostic tool and heralding a new era of enhanced patient care outcomes.

Objective:To observe the efficacy of external diaphragm pacing (EDP) combined with recombinant human growth hormone (rhGH) in the treatment of severe chronic obstructive pulmonary disease (CDOP).Methods:By the prospective study method, 80 patients with severe COPD were admitted to the Xianju People′s Hospital(Zhejiang Southeast Campus of Zhejiang Provincial People′s Hospital)/Xianju Hospital Affiliated to Hangzhou Medical College from April 2021 to April 2023 were divided into the combined group and the conventional group by the random number table method, with 40 cases in each group. All of them received anti-infection, nutritional support, and other conventional treatment. In addition, the combined group was given EDP+rhGH treatment, and they were intervened for 20 d. The diaphragm function, nutrition, pulmonary function, and serum levels of interleukin (IL-6), IL-23, type Ⅱ alveolar cell surface antigen (KL-6) changes before and after treatment and prognosis were compared between the two groups.Results:After treatment, the diaphragm function index diaphragm maximum expiratory pressure (MIP), diaphragm thickness (DTei), and diaphragm mobility (DE) in the combined group were higher than those in the conventional group: (45.36 ± 7.04) cmH 2O (1 cmH 2O = 0.098 kPa) vs. (42.28 ± 6.43) cmH 2O, (0.32 ± 0.12) cm vs. (0.27 ± 0.06) cm, (3.40 ± 1.02) cm vs. (1.85 ± 0.64) cm, there were statistical differences ( P<0.05). After treatment, the nutritional status indexes of serum albumin (ALB), transferrin (Tf), and total protein (TP) in the combined group were higher than those in the conventional group: (34.62 ± 5.13) g/L vs. (31.75 ± 4.93) g/L, (2.21 ± 0.46) g/L vs. (2.00 ± 0.42) g/L, (63.80 ± 8.25) g/L vs. (60.24 ± 6.97) g/L, there were statistical differences ( P<0.05). After treatment, the percentage of forced expiratory volume in the first second (FEV 1) to the expected value (FEV 1%) and the ratio of FEV 1 to forced vital capacity (FEV 1/FVC) in the combined group were higher than those in the conventional group: (60.17 ± 6.30)% vs. (57.25 ± 6.24)%, (61.30 ± 7.04)% vs. (57.12 ± 7.25)%, there were statistical differences ( P<0.05). After treatment, the levels of IL-6, IL-23, and KL-6 in the combined group were lower than those in the conventional group: (23.13 ± 4.26) ng/L vs. (26.60 ± 4.75) ng/L, (20.84 ± 6.16) μg/L vs. (25.00 ± 5.89) μg/L, (375.10 ± 45.18) kU/L vs. (400.25 ± 46.27) kU/L, there were statistical differences ( P<0.05). The mechanical ventilation time and intensive care unit stay time in the combined group were shorter than those in the conventional group: (150.46 ± 10.24) h vs. (189.67 ± 15.43) h, (7.00 ± 2.03) d vs. (9.84 ± 2.72) d, there were statistical differences ( P<0.05). The rate of extubation within 1 week in the combined group was higher than that in the conventional group, and the 28-day mortality was lower than that in the conventional group: 90.00%(36/40) vs. 72.50%(29/40), 5.00%(2/40) vs. 22.50%(9/40), there were statistical differences ( χ2 = 4.02, 5.16, P<0.05). Conclusions:In the patients with severe COPD, EDP combined with rhGH can significantly improve the diaphragm function, nutritional status, and lung function, decrease serum IL-6, IL-23, and KL-6 levels, shorten the mechanical ventilation time, and reduce the 28-day mortality.

Objective:To investigate the efficacy and safety of intravesical injections of botulinum toxin A (BTX-A) for the treatment of pediatric refractory urinary frequency and incontinence (UFI), and to analyze the factors predicting the therapeutic effect of BTX-A injections.Methods:A retrospective case series study was made on 35 children with UFI [(12.3±4.2) years old], including 13 males (37.1%) and 22 females (62.9%), treated in the First Affiliated Hospital of Zhengzhou University from January 2021 to March 2024.Urotherapy and drug treatments were ineffective in all children, who then received intravesical injections of BTX-A.The urodynamic study (UDS) was performed 1 week before treatment and 3 months after treatment, and the Overactive Bladder Symptom Score (OABSS) and Incontinence Quality of Life (I-QOL) were collected.Perioperative and postoperative adverse events were also recorded.A global response assessment (GRA) score of ≥2 at 3 months postoperatively was defined as effective treatment.According to the postoperative GRA score, the patients were divided into effective and ineffective groups to explore the predictive factors affecting the outcome of BTX-A treatment, such as age, gender, preoperative urodynamic parameters, and the types of urinary incontinence. t-test was used to compare quantitative data such as age, UDS parameters, OABSS, and I-QOL scores.The comparison of count data such as gender and urinary incontinence types was conducted using Fisher′s exact test. Results:The bladder compliance, bladder capacity ratio, OABSS and I-QOL scores of patients significantly improved after BTX-A injection (all P<0.05).The 77.1% (27/35) of the patients were satisfied with BTX-A treatment effects.The main adverse event during the follow-up was a temporary increase in postvoid residual urine after injecting BTX-A (7 cases), which was alleviated by the Creade action or clean intermittent catheterization.There was significant difference in age [(13.00±4.32) years vs.(10.00±2.67) years] and preoperative bladder compliance [(11.21±5.74) mL/cmH 2O vs.(5.13±2.42) mL/cmH 2O] between effective (27 cases) and ineffective groups (8 cases) ( t=2.383, 2.899, all P<0.05).The differences in preoperative bladder capacity ratio, maximum filling detrusor pressure, postvoid residual urine, voiding efficiency, gender, and the types of urinary incontinence were not statistically significant between the two groups (all P>0.05). Conclusions:Intravesical injection of BTX-A is a safe and effective treatment for children with refractory UFI.A young age and poor bladder compliance at treatment are associated with poor prognosis of BTX-A treatment.

The clinical data, laboratory testing, genetic testing results, diagnosis and treatment process of a child with PERCHING syndrome diagnosed and treated in the Department of Neonatology, the Third Affiliated Hospital of Zhengzhou University in June 2022 were retrospectively analyzed, and the relevant literatures were reviewed.The proband mainly presented with dyspnea and feeding difficulties after delivery, facial nevus flammeus, protrusion of eyes, small fissure of eyes, wide nasal root, limited opening of mouth, slightly high palatal arch, special posture, cryptorchid, hypospadias, and high muscle tone of limbs.Magnetic resonance imaging of the brain suggested possible agenesis of corpus callosum.Genetic testing showed complex heterozygous variations in the KLHL7 gene, and the two mutation sites have not been previously reported.A case of PERCHING syndrome caused by the KLHL7 gene mutation in China was reported for the first time, which provided new ideas for the diagnosis and treatment of children with PERCHING syndrome and reliable genetic evidence for family reproduction.

Objective:To analyze the accuracy of lung ultrasound and chest X-ray in the diagnosis of neonatal pulmonary disease.Methods:We prospectively collected newborns that needed chest X-ray examination to diagnose pulmonary disease from twelve neonatal intensive care units across the country between June 2019 and April 2020.Each newborn was examined by lung ultrasound within two hours after chest X-ray examination.All chest X-ray and lung ultrasound images were independently read by a radiologist and a sonographer.When there was a disagreement, a panel of two experienced physicians made a final diagnosis based on the clinical history, chest X-ray and lung ultrasound images.Results:A total of 1 100 newborns were enrolled in our study.The diagnostic agreement between chest X-ray and lung ultrasound(Cohen′s kappa coefficient=0.347) was fair.Lung ultrasound(area under the curve=0.778; 95% CI 0.753-0.803) performed significantly better than chest X-ray(area under the curve=0.513; 95% CI 0.483-0.543) in the diagnosis of transient tachypnea of the newborn( P<0.001). The accuracy of lung ultrasound in diagnosing neonatal respiratory distress syndrome, meconium aspiration syndrome, pneumonia and neonatal pulmonary atelectasis was similar to that of chest X-ray. Conclusion:Lung ultrasound, as a low-cost, simple and radiation-free auxiliary examination method, has a diagnostic accuracy close to or even better than that of chest X-ray, which may replace chest X-ray in the diagnosis of some neonatal lung diseases.It should be noted that both chest X-ray and lung ultrasound can only be used as auxiliary means for the diagnosis of lung diseases, and it is necessary to combine imaging with the clinical history and presentation.
