Objective To evaluate the clinical value of loop-mediated isothermal amplification(LAMP)for rapid detection of neonatal infectious pathogens.Methods Biological samples(cord blood and neonatal blood or sputum within 48 hours of birth)of 167 suspected neonates and premature infants delivered in Jinhua Maternal and Child Health Hospital from June 2021 to December 2022 were collected and tested by LAMP method and bacterial culture method respectively.The results of the two methods were compared consistent-ly.Using the bacterial culture method as the standard,the positive rate of LAMP method was evaluated in de-tecting common pathogens in neonatal infections.Results Among the 167 specimens,the positive rate of pathogen detection by LAMP method(24.0％)was higher than that by bacterial culture method(15.0％),and the difference was statistically significant(x2=4.30,P＜0.05).The positive rate of LAMP method for detecting methicillin-resistant Staphylococcus aureus was higher than that of bacterial culture method,and the difference was statistically significant(x2=15.59,P＜0.01).Conclusion Compared with bacterial culture method,LAMP method has a higher positive rate for detecting methicillin-resistant Staphylococcus aureus,and can quickly and accurately diagnose the pathogenic bacteria of neonatal infections,providing a basis for the rapid development of clinical diagnosis and treatment strategies.

Objective To investigate the safety and feasibility of modified gasless trans-subclavian approach endoscopic total thyroidectomy for papillary thyroid carcinoma(PTC).Methods We retrospectively analyzed the clinical data of consecutive 82 patients with PTC who underwent the modified gasless trans-subclavian approach endoscopic total thyroidectomy in the Department of Head and Neck Surgery,Sir Run Run Shaw Hospital,Affiliated with the Zhejiang University School of Medicine,from March 2022 to June 2023.Results All operations were successfully completed under endoscopy approach without transfer to open surgery.The maximum diameter of PTC was(6.6±5.4)mm.The operation duration was(156.5±32.7)min,and the number of lymph nodes in the central compartment was(12.3±6.4).The postoperative hospital stay was(3.3±1.2)d.Postoperative complications included two cases of transient hypoparathyroidism and six cases of transient recurrent laryngeal nerve injury.All the patients recovered in one month.One case of postoperative bleeding was observed.No permanent laryngeal nerve injury,permanent hypoparathyroidism or incision infection occurred.Conclusion The gasless trans-subclavian approach endoscopic total thyroidectomy is a feasible and safety approach in selected PTC patients.The lymph nodes in the central compartment are thoroughly dissected.This approach has obvious advantages in functional protection of the anterior cervical region,and has clinical application value.

OBJECTIVE:Percutaneous sacroiliac screw internal fixation has become the main surgical procedure for the treatment of posterior pelvic ring fractures;however,the unassisted closure operation requires high operator experience and repeated fluoroscopy increases the radiation hazard for patients and medical personnel.This article compares the clinical efficacy of robot-assisted versus unassisted percutaneous sacroiliac screw placement for posterior pelvic ring fractures by meta-analysis. METHODS:Computer searches of CNKI,WanFang,VIP,CBM,PubMed,Embase,Cochrane Library and ClinicalTrials.gov were conducted from the time of database inception to December 2022.The literature on the clinical efficacy of robot-assisted versus freehand percutaneous sacroiliac screw placement in the treatment of posterior pelvic ring fractures was collected in and outside China.The data were independently screened and extracted by two investigators according to the inclusion and exclusion criteria,respectively.The quality of randomized controlled trials was evaluated using Cochrane risk assessment criteria.The quality of included cohort studies was assessed using the Newcastle-Ottawa Scale.Meta-analysis was performed using RevMan 5.4 software for inclusion metrics.Outcome metrics included operative time,intraoperative bleeding,fluoroscopy time,fluoroscopy frequency,number of holes drilled,Majeed postoperative function score,the excellent and good rates of Matta fracture reduction,the excellent and good rates of Gras screw position,fracture healing time and complications. RESULTS:(1)A total of 13 publications were included,2 were randomized controlled trials both referring to randomized methods,11 non-randomized controlled studies were evaluated for quality of literature according to the Newcastle-Ottawa Scale,1 scored 8,9 scored 7;and 1 scored 6;the quality of literature was good.A total of 748 patients were included,including 430 in the robot-assisted group and 318 in the freehand group.(2)The results of the meta-analysis showed that the operative time(MD=-28.30,95%CI:-40.20 to-16.40),intraoperative bleeding(MD=-6.36,95%CI:-10.06 to-2.66),intraoperative fluoroscopy time(MD=-12.13,95%CI:-19.54 to-4.72),intraoperative fluoroscopy frequency(MD=-17.39,95%CI:-29.00 to-5.78),number of intraoperative needle drillings(SMD=-9.50,95%CI:-14.27 to-4.73)and the excellent and good rates of Gras screw position(OR=8.65,95%Cl:3.26-22.92)in the robot-assisted group were significantly better than those in the freehand group(P<0.05).(3)In the robot-assisted group,the overall postoperative complication rate was significantly reduced(OR=0.10,95%Cl:0.02-0.48,P<0.05).(4)No significant difference was detected in fracture healing time(MD=-0.08,95%CI:-0.21,0.06),the excellent and good rates of Matta fracture repositioning rate(OR=2.06,95%Cl:0.97-4.39),and Majeed functional score(MD=0.91,95%CI:-0.31-2.13)between both groups(P>0.05). CONCLUSION:Compared with freehand sacroiliac joint nailing,robotic assistance shortens the operative time,reduces intraoperative bleeding,decreases radiation damage to patients and medical staff,improves the excellent and good rate of screw position,and reduces the overall incidence of postoperative complications in patients,but there was no significant improvement in fracture reduction quality,fracture healing time,and postoperative function.In the future,more large-sample,multicenter,and high-quality randomized controlled trials are still needed to verify.

Objective:To evaluate the effect of sodium sivelestat on the expression of specialized pro-resolving mediators (SPMs) synthesis enzymes in mice with lipopolysaccharide (LPS)-induced acute lung injury (ALI).Methods:Eighteen SPF healthy male C57BL/6 mice, aged 6-8 weeks, weighing 20-25 g, were divided into 3 groups ( n=6 each) using a random number table method: control group (C group), LPS-induced ALI group (ALI group), and LPS-induced ALI + sodium sivelestat group (ALI+ SV group). ALI was induced by intravenous injection of LPS 15 mg/kg through the tail vein. Sodium sivelestat 50 mg/kg was intraperitoneally injected at 1 h after LPS administration. At 12 h after LPS administration, blood samples were collected from the eyeballs for routine blood tests, and the remaining blood was processed for serum extraction. The mice were sacrificed after anesthesia, and lung tissues were collected to determine the wet/dry weight (W/D) ratio, serum concentrations of interleukin-1beta (IL-1β) and IL-10 (by enzyme-linked immunosorbent assay), expression of neutrophil elastase (NE) and SPMs synthesis enzymes 5-lipoxygenase (5-LOX), 12-lipoxygenase (12-LOX), and 15-lipoxygenase (15-LOX) in lung tissues (by Western blot) and to examine the pathological changes of lung tissues which were scored. Results:Compared with C group, the lung injury scores, W/D ratio, white blood cell counts, percentage of neutrophil, and serum IL-1β and IL-10 concentrations were significantly increased, the expression of NE was up-regulated, and the expression of 5-LOX, 12-LOX and 15-LOX was down-regulated in ALI group ( P<0.05). Compared with ALI group, the lung injury scores, W/D ratio, white blood cell counts, percentage of neutrophil, and serum IL-1β concentration were significantly decreased, the serum IL-10 concentration was increased, the expression of NE was down-regulated, and the expression of 5-LOX, 12-LOX and 15-LOX was up-regulated in ALI+ SV group ( P<0.05). Conclusions:The mechanism by which sodium sivelestat alleviates LPS-induced ALI may be related to up-regulating the expression of SPMs synthesis enzyme and promoting the resolution of pulmonary inflammation in mice.

A 1-year and 9-month-old male proband presented with clustered rice grain-sized flat smooth red papules on the face, trunk and limbs for 1.5 years, without fever, joint swelling, or pain. The proband′s sister aged 7 years ever experienced swelling and pain in the finger joints of both hands at the age of 2 years, and had intermittent fever and papules all over the body at the same time, and the papules gradually regressed with the subsidence of fever. The proband′s mother aged 27 years suffered from swelling and pain in the finger joints of both hands when she was young, gradually leading to finger deformities, and experienced intermittent knee swelling and pain at the age of 12 years without obvious skin lesions on the body. No abnormality was found in ophthalmological and systemic physical examinations of the 3 patients. Whole-exome sequencing showed that the proband, his sister and mother all had a heterozygous missense mutation c.1001G>A (p.R334Q) in exon 4 of the NOD2 gene. A diagnosis of Blau syndrome was made. The proband was treated with topical moisturizing cream all over the body; during the 52-week follow-up, no joint swelling and pain or eye symptoms were found in the proband, while erythema and depressed scars were observed on the face, trunk and limbs. The proband′s sister and mother were treated with subcutaneous injections of adalimumab at initial doses of 40 mg and 80 mg respectively, followed 1 week later by injections at 20 mg and 40 mg respectively, and then treated with injections at 20 mg and 40 mg respectively every 2 weeks; after 12-week treatment, the joint swelling and pain were markedly relieved in the proband′s sister and mother, and most skin lesions subsided in the proband′s sister; at week 52 during the follow-up, there was no joint swelling, pain or skin lesions in the proband′s sister, and there was no swelling or pain in the knee joints of the proband′s mother, while no improvement was observed in her finger deformities. During the treatment, no eye symptoms or adverse reactions were observed neither in the proband′s sister nor in his mother.

Objective:To investigate changes in disease status and their influencing factors in patients with moderate to severe plaque psoriasis treated with biologics during the coronavirus disease 2019 (COVID-19) pandemic.Methods:Through printed or electronic questionnaires during February 10 th - 20 th, 2023, data were collected from patients with moderate to severe plaque psoriasis treated with biologics in Henan Provincial People′s Hospital from June 2019 to January 2023, and changes in the disease condition during the COVID-19 pandemic were investigated. The t test or chi-square test was used for comparisons between groups, univariate analysis and multivariate logistic regression analysis were conducted to investigate the factors contributing to the exacerbation of psoriasis, and stratified analysis was employed to evaluate the disease progression among the patients receiving different biologic therapies following treatment delays. Results:A total of 177 patients with moderate to severe plaque psoriasis were collected, including 115 males and 62 females; they were aged 6 - 83 (38.69 ± 14.18) years, with disease duration of 1 - 50 (13.48 ± 9.70) years. Among the patients, 74 (41.81%) experienced psoriasis exacerbation, 154 (87.01%) developed COVID-19, and 90 (50.85%) experienced delays in psoriasis treatment due to the pandemic. The results of univariate analysis indicated significant associations of psoriasis exacerbation with treatment delays, irregular treatment before the pandemic, and incomplete clearance of skin lesions ( P < 0.001 or 0.05), while no correlations were observed between psoriasis exacerbation and COVID-19 or gender (both P > 0.05). Multivariate logistic regression analysis demonstrated that psoriasis exacerbation was associated with treatment delays due to COVID-19 ( OR = 3.34, 95% CI: 1.35 - 8.22, P = 0.009) and incomplete clearance of skin lesions ( OR = 3.10, 95% CI: 1.28 - 7.50, P = 0.012), but not associated with irregular treatment before the pandemic ( P = 0.130). Among the patients treated with adalimumab, secukinumab, ustekinumab, and ixekizumab, those experiencing treatment delays exhibited higher rates of psoriasis exacerbation than those without treatment delays (all P < 0.05) . Conclusion:Patients with moderate to severe plaque psoriasis undergoing biologic therapy are prone to disease exacerbation when treatment is delayed due to COVID-19, especially those with incomplete lesion clearance.

Objective:To explore the prevalence and independent associated factors of vascular calcification (VC) in non-dialysis chronic kidney disease (CKD) patients of stage 3-5.Methods:It was a single-center cross-sectional observational study. Non-dialysis stage 3-5 CKD patients ≥18 years old who were admitted to the Department of Nephrology, the First Affiliated Hospital of Sun Yat-sen University from May 1, 2022 to December 31, 2022 with VC evaluation were enrolled. The patients' general information, laboratory examination and imaging data were collected. Coronary artery calcification (CAC), thoracic aorta calcification (TAC), abdominal aorta calcification (AAC), carotid artery calcification and aortic valve calcification (AVC) were evaluated by cardiac-gated electron-beam CT (EBCT) scans, lateral lumbar x-ray, cervical macrovascular ultrasound and echocardiography, respectively. The differences in clinical data and the prevalence of VC at different sites of patients with different CKD stages were compared, and the prevalence of VC at different sites of patients in different age groups [youth group (18-44 years old), middle-aged group (45-64 years old) and elderly group (≥65 years old)] and patients with or without diabetes were compared. Multivariate logistic regression analysis was used to analyse the independent associated factors of VC for different areas.Results:A total of 206 patients aged (51±14) years were included, including 129 (62.6%) males. There were 44 patients with CKD stage 3 (21.4%), 51 patients with CKD stage 4 (24.8%), and 111 patients with CKD stage 5 (53.9%). CKD was caused by chronic glomerulonephritis [104 cases (50.5%)], diabetic kidney damage [35 cases (17.0%)], hypertensive kidney damage [29 cases (14.1%)] and others [38 cases (18.4%)]. Among 206 patients, 131 (63.6%) exhibited cardiovascular calcification, and the prevalence of CAC, TAC, AAC, carotid artery calcification, and AVC was 37.9%, 43.7%, 37.9%, 35.9% and 9.7%, respectively. The overall prevalence of VC in young, middle-aged and elderly patients was 24.6%, 73.6% and 97.4%, respectively. With the increase of age, the prevalence of VC in each site gradually increased, and the increasing trend was statistically significant (all P<0.001). The overall prevalence of VC in CKD patients with diabetes was 92.5% (62/67), and the prevalence of VC at each site in the patients with diabetes was significantly higher than that in the patients without diabetes (all P<0.001). Multivariate logistic regression analysis revealed that age (every 10 years increase, OR=2.51, 95% CI 1.77-3.56, P<0.001), hypertension ( OR=5.88, 95% CI 1.57-22.10, P=0.009), and diabetes ( OR=4.66, 95% CI 2.10-10.35, P<0.001) were independently correlated with CAC; Age (every 10 years increase, OR=6.43, 95% CI 3.64-11.36, P<0.001) and hypertension ( OR=6.09, 95% CI 1.33-27.84, P=0.020) were independently correlated with TAC; Female ( OR=0.23, 95% CI 0.07-0.72, P=0.011), age (every 10 years increase, OR=3.90, 95% CI 2.42-6.29, P<0.001), diabetes ( OR=5.37, 95% CI 2.19-13.19, P<0.001) and serum magnesium ( OR=0.01,95% CI 0-0.35, P=0.014) were independently correlated with AAC. Moreover, age and diabetes were independently correlated with carotid artery calcification, AVC and overall VC Conclusions:The prevalence of VC in non-dialysis CKD patients of stage 3-5 is 63.59%, of which CAC reaches 37.9%, TAC is the most common one (43.7%), while AVC is the least one (9.7%). Age and diabetes are the independent associated factors for VC of all sites except TAC, while hypertension is an independent associated factor for both CAC and TAC.
