BACKGROUND:Many studies have focused on acupuncture,such as silver needles,for the treatment of lumbar disc herniation,but there are few studies based on the myofascial trigger point theory. OBJECTIVE:To observe the effects of silver needle comprehensive therapy on the ultrasound morphology and clinical efficacy of multifidus muscles in patients with lumbar disc herniation based on the theory of myofascial trigger points. METHODS:A total of 159 patients with lumbar disc herniation who were seen from January 2022 to April 2023 were selected as the research subjects and randomly divided into three groups:conventional group(n=53),traditional acupuncture group(n=53),and silver needle group(n=53).The conventional group received routine western medicine treatment;the traditional acupuncture group used traditional acupuncture therapy based on meridian pathways and symptom localization;and the silver needle group used silver needle warm acupuncture at myofascial trigger points for intervention.All three groups received continuous treatment for 4 weeks.The number of myofascial trigger points,pain assessment,lumbar function evaluation,ultrasound morphology changes of multifidus muscles,clinical efficacy,and traditional Chinese medicine symptom score were recorded before and after treatment in the three groups. RESULTS AND CONCLUSION:(1)After treatment,the number of myofascial trigger points in the lumbar muscles decreased in all groups,and the silver needle group showed a significant reduction compared with the traditional acupuncture group and the conventional group(P<0.05).(2)The pain rating index score,visual analogue scale score,present pain intensity score,Oswestry disability index score,and Roland-Morris disability questionnaire score in the silver needle group were lower than those in the traditional acupuncture group and the conventional group(P<0.05).(3)The ultrasound morphology indexes of multifidus muscles in the silver needle group were superior to those in the traditional acupuncture group and the conventional western medicine group(P<0.05).(4)Traditional Chinese medicine symptom scores in the silver needle group were lower than those in the traditional acupuncture group and the conventional western medicine group(P<0.05).(5)There were significant differences in clinical efficacy among the three groups(P<0.05).To conclude,applying silver needle comprehensive therapy based on the theory of myofascial trigger points can effectively reduce pain,improve clinical efficacy,and enhance lumbar spine dysfunction and multifidus muscle morphology in patients with lumbar disc herniation.

This study analyzed the epidemiological characteristics and trends of respiratory syncytial virus (RSV) infections among inpatients with acute respiratory infections (ARI) in a children′s hospital in Shenzhen City inpatients from 2020 to 2023. From January 2020 to December 2023, multiple reverse transcription polymerase chain reaction (RT-PCR) combined with capillary electrophoresis fragment analysis technology was used to detect the nucleic acids of 12 respiratory pathogens, including RSV, in hospitalized children diagnosed with ARI. The patients were divided into six age groups: 0 to <6 months, 6 months to <1 year, 1 to <2 years, 2 to <5 years, 5 to <10 years, and 10 to <18 years. A total of 53 033 children were tested, including 6 830 RSV positive cases, with an overall positivity rate of 12.88%. The annual RSV positivity rates from 2020 to 2023 were 20.04%, 16.18%, 4.89%, and 13.33%, respectively, with statistically significant differences between the years ( χ2=1 185.994, P<0.001). The positive rate of RSV detection decreased with increasing age across all years (all P trend<0.05). From 2020 to 2023, the proportion of RSV-positive cases aged 2 to 5 years and older showed an increasing trend ( P trend<0.001 for all years). Compared to 2023, the median age of RSV-infected children was lower in 2020 ( Z=7.826, P<0.001) and 2021 ( Z=6.106, P<0.001). The proportion of severe infections requiring ICU admission did not change significantly across all years ( χ2=0.179, P=0.981). The RSV epidemic season in 2020 mainly occurred during 28-43 weeks, and in 2021, it spanned from 22-43 weeks. However, in 2022, the season was delayed until the 49th week and lasted for three weeks. In 2023, the seasonal epidemic appeared earlier, starting in the 14th week and lasting for 28 weeks. From 2020 to 2023, the rate of RSV co-infections with other pathogens (mycoplasma pneumoniae, human parainfluenza virus, human bocavirus, human coronavirus, human metapneumovirus, and influenza A) significantly increased (all P trend<0.01). In conclusion, the epidemiological characteristics of RSV infections in Shenzhen Children′s Hospital changed from 2020 to 2023. In 2022, there were only delayed, low-intensity and short-lived seasonal epidemics. However, in 2023, there was an earlier and prolonged epidemic, with increased infections in children aged 2 to 5 years and older and a rise in co-infections, while the proportion of severe infections requiring ICU admission remained unchanged.

Objective:To evaluate the improvement in the outcome of intracapsular condylar fractures(ICFs)treatment with pre-cise soft tissue reduction in combination with open reduction and internal fixation(PSTR-ORIF)by comparson with traditional open reduction and internal fixation(T-ORIF).Methods:40 patients with ICFs were treated by T-ORIF and PSTR-ORIF(n=20)re-spectively.Preoperative and 6-month postoperative whole-mouth panoramic tomography,CT and MRI imaging data were analyzed,the repositioning of the soft and hard tissues of temporomandibular joints(TMJs),the Helkimo index,clinical symptoms and subjec-tive symptoms were compared between the 2 groups.Results:In PSTR-ORIF(26 sides)and T-ORIF(27 sides)groups,the rate of complete anatomical restoration of fractured segments at 6 months after surgery was 96.15％and 81.48％,and the overall effective rate of ICF articular disc restoration was 96.15％and 74.07％respectively,the height of the ascending mandibular branch was bet-ter restored in patients with B-type fracture after surgery(P＜0.05).At 6 months postoperatively,patients in the PSTR-ORIF group showed significant improvement in mouth opening,mandibular anterior extension distance,and lateral movement compared with the T-ORIF group(P＜0.05).The Helkimo index showed that the PSTR-ORIF group got a significant improvement in the complaint symptom index score and the clinical symptom index score compared with the T-ORIF group(P＜0.05).Conclusion:PSTR-ORIF is more effective than T-ORIF in the treatment of ICFs for the healing of condylar fractures,restore postoperative TMJ mobility and reduce the postoperative joint discomfort through good repositioning of soft tissues.

Objective:To analyze the status of nurse-led clinics at home and abroad, and to explore the research hotspots and development trends.Methods:China National Knowledge Infrastructure and Web of Science Core Collection database were searched for literature on nurse-led clinics. The search period was from January 1, 2000 to May 26, 2024. Visual analysis was implemented using CiteSpace software on the collected literature.Results:A total of 206 articles in Chinese and 1 990 articles in English were included. The number of English language publications in nurse-led clinics was higher than that of Chinese language publications, and the top three countries in terms of English language publications were the United Kingdom (533), the United States (420), and Australia (355). The number of publications in the Chinese literature grew slowly, and the journal with the highest number of publications was Chinese Nursing Management (69). Keywords such as "nurse specialist", "nursing management" and "health education" in the Chinese literature and "quality of life", "management" and "randomized controlled trial" in the English literature had a high degree of centrality. Rehabilitative care and hospice care for oncology patients was a common research trend in international nurse-led clinics. Conclusions:Nurse-led clinics have gained widespread attention as a model of advanced nursing practice. China's nurse-led clinics in general show a good development trend, but the amount of relevant research publications is relatively small, and the level of research still needs to be further improved.

Objective:To explore the screening value of platelet parameters from blood cell analysis for MYH9-related disorders(MYH9-RD).Methods:A cross-sectional study was conducted with 38 patients diagnosed with MYH9-RD at Shenzhen Children's Hospital from May 1, 2016, to August 31, 2024, including 24 males and 14 females; the median age was 11.5 (3.8, 35) years; categorized by gene mutation location into "head region" ( n=8 ) and "tail region" ( n=30); and by clinical manifestations into " isolated hematological manifestations" ( n=16) and "hematological manifestations with extra-hematological involvement"( n=22). The control groups included 39 cases of immune thrombocytopenia (ITP), 38 cases of acute lymphoblastic leukemia (ALL), and 40 healthy individuals. Platelet-related parameters were detected by hematology analyzer, and platelet counts and sizes were confirmed by manually counting and microscopic observation. Kruskal-Wallis test was used to compare platelet parameters between MYH9-RD and control groups. Receiver operating characteristic (ROC) curves were used to assess the diagnostic efficacy of platelet parameters for MYH9-RD. Results:In MYH9-RD patients the median value of mean platelet volume (MPV) was 13.4 (11.2, 14.7) fl, immature platelet fraction (IPF) was 52.7% (43.5%, 58.0%), platelet large cell ratio(PLCR) was 57.6 %(45.0%, 62.9%), and microscopic large platelet ratio (PLCR-M) was 30.0% (25.0%, 30.0%).And those values weresignificantly higher than in ITP, ALL, and healthy controls (all P<0.05). Patients with MYH9 gene "head region" mutations had a lower platelet count [24.5 (15.0, 47.5)×10 9/L]than those with "tail region" mutations [69.0 (49.5, 86.3) ×10 9/L]( Z=-3.493, P<0.001), but a higher IPF ( t=2.024, P=0.044).Patients with "extra-hematological involvement had a lower platelet count than those with "isolated hematological manifestations" ( t=-2.015, P=0.043). The optimal cutoff value for diagnosing MYH9-RD with IPF was 26.7%, with a sensitivity of 100% and specificity of 98.7%; the area under the curve was 0.999 (95% CI 0.995-1.000), which was superior toMPV, PLCR and PLCR-M parameters. Conclusion:IPF is superior to other platelet parameters sush as MPV,showing high diagnostic efficacy in distinguishing MYH9-RD from ITP and ALL. It can be used as a simple and effective indicator for early screening of MYH9-RD.
