OBJECTIVE: Since Omicron will likely persist, this trial evaluates the safety and efficacy of Shufeng Jiedu Granule (SFJDG) for mild Omicron infection, aims at finding new therapies especially for home-treated patients. METHODS: This randomized, double-blind, placebo-controlled, multi-center phase III trial involves 844 patients, divided into a treatment group (422) and control group (422). Participants will receive SFJDG or placebo for 7 d (1.2 g/bag, 2 bags, 3 times/d). Hospital evaluations will be done on days 1 and 8, with telephone assessments on days 3 and 5. Follow-up continues on days 10 and 14. Diary cards will track symptom scores and safety data. The primary outcome is the time to sustained clinical recovery from corona virus disease 2019 (COVID-19) symptoms. An interim analysis will occur after 70 % of patients complete follow-up, with Type I error correction (α1 = 0.015) at interim analysis based on O'Brien-Fleming-type cumulative error spending function. RESULTS: This phase III trial evaluates the efficacy and safety of SFJDG for mild COVID-19, focusing on real-world applicability for home-managed patients. The study's randomized, double-blind, placebo-controlled design ensures methodological rigor, while its comprehensive outcome measures address both symptom recovery and treatment safety. By emphasizing symptom resolution and recovery time, the trial aligns with the clinical priorities for managing mild cases of COVID-19. The findings could offer valuable insights into SFJDG's role in improving patient outcomes and addressing gaps left by existing antiviral therapies, particularly in symptom management. CONCLUSION The global risk assessment remains high due to the ongoing virulence of SARS-CoV-2 Omicron sub-lineages. This Phase III study adopts a robust methodology to investigate SFJDG as a treatment for mild COVID-19 as well as it's effectiveness and safety. Furthermore, this study aim to provide sufficient scientific evidence for the market registration of SFJDG especially for home-treated patients. If successful, SFJDG could be a meaningful addition to therapeutic options for mild infections, supporting public health strategies in managing the ongoing impact of SARS-CoV-2.

ObjectiveThis paper aims to verify the therapeutic effect of Cranial Painkiller pills' extract powder prepared by the new process on the rat's trigeminal neuralgia model caused by infraorbital injection of Talci Pulvis， evaluate its potential clinical application value， and compare the therapeutic effect with that of Cranial Painkiller granules， so as to provide data support for the application of the Cranial Painkiller pills' extract powder and precise treatment. MethodsThe rat's trigeminal neuralgia model was constructed by infraorbital injection of Talci Pulvis， and the rats were randomly divided into the normal group， model group， carbamazepine group （60 mg·kg^-1）， Cranial Painkiller granules group （2.70 g·kg^-1）， and low， medium， and high dosage groups of Cranial Painkiller pills' extract powder （1.35， 2.70， 5.40 g·kg^-1） according to the basal mechanical pain thresholds， and there were 10 rats in each group. The drug was administered by gavage to each group 2 h after modeling， and distilled water was given by gavage to the normal and model groups under the same conditions once a day for 10 d. Von Frey brushes were used to measure mechanical pain thresholds in rats. Hematoxylin-eosin （HE） staining was used to detect pathological changes in the trigeminal ganglion， and enzyme-linked immunosorbent assay （ELISA） was used to detect the inflammatory factors interleukin-1 （IL-1）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， and tumor necrosis factor-α （TNF-α） levels in rat serum， as well as neuropeptide substance P （SP） and β-endorphin （β-EP） levels in rat brain tissue. Western blot technique was used to detect the levels of NLRP3， ASC， Caspase-1， and OTULIN proteins in rat brain tissue. ResultsCompared with the normal group， the pain threshold of rats in the model group showed a continuous significant decrease （P<0.01）. The pathological damage of brain tissue was significant （P<0.01）， and the inflammatory levels of IL-1， IL-6， IL-8， and TNF-α in serum were significantly elevated （P<0.01）. The level of the SP in the brain tissue was significantly elevated （P<0.01）， and the level of β-EP was significantly reduced （P<0.01）， while the level of OTULIN was significantly reduced， and NLRP3， ASC， and Caspase-1 protein levels were significantly elevated （P<0.01）. After administration of the drug， compared with the model group， the pain threshold of each dose group of the Cranial Painkiller pills' extract powder and the Cranial Painkiller granules group significantly increased （P<0.01）. The inflammatory levels of IL-1， IL-6， IL-8， and TNF-α and SP levels significantly decreased （P<0.01）， and the β-EP levels were significantly elevated （P<0.01）， while the levels of OTULIN protein were significantly elevated （P<0.05， P<0.01）， and the levels of NLRP3， ASC proteins were decreased （P<0.01）in high dose Cranial Painkiller pills' extract powder. Meanwhile， compared with those in the model group， the trigeminal ganglion lesions of rats in the Cranial Painkiller pills' extract powder and Cranial Painkiller granules groups showed different degrees of improvement （P<0.05， P<0.01）. ConclusionThe Cranial Painkiller pills' extract powder has significant therapeutic effects on the rat model of trigeminal neuralgia induced by infraorbital injection of Talci Pulvis， and its mechanism is related to the improvement of OTULIN-regulated neuroinflammation.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective:To evaluate the safety and efficacy of laparoscopes adhesiolysis in the treatment of adhesive intestinal obstruction.Methods:A retrospective analysis was conducted on the clinical data of 30 patients with adhesive intestinal obstruction who underwent laparoscopes adhesiolysis at the First Affiliated Hospital, Zhejiang University School of Medicine between January 2021 and December 2024. The demographics, surgical parameters and postoperative complications were recorded.Results:Among the 30 patients, 16 were male and 14 were female, with age of (55.93 ± 13.83) years. A history of abdominal surgery was present in 25 patients (83.3%). Of the surgeries, 4 cases (13.3%) were performed as emergency procedures and 26 cases (86.7%) were elective. The operative time was (125.57 ± 48.25) min, and intraoperative blood loss was (26.17 ± 16.90) ml.

Objective:To compare gamma pass rates for ultra-long target volumes of cervical cancer between individual measurements by moving the phantom isocenter and segmented measurements combined with merging and to assess the influence of scattering blocks on verification result during segmented measurements.Methods:A retrospective study was conducted on 24 cervical cancer patients with ultra-long target volumes (lengths: 23.5–36.0 cm) treated using helical tomotherapy. Two measurement methods were used to verify the gamma pass rates: individual measurements by moving the phantom isocenter and segmented measurements combined with merging. For the first measurement method, the patients′ treatment plans were transferred to the ArcCheck phantom. After the dose distribution was calculated and exported, the gamma pass rates measured and calculated were compared. For the segmented measurements, a 50-cm-long virtual phantom was imported, and the treatment plans of patients were then transferred to the virtual phantom. Afterward, the dose distribution of the virtual phantom was calculated and exported. Then, two dose measurements were conducted under upward and downward setup of the ArcCheck phantom. Two dose measurement files were obtained and then fused to produce a merged file. Then, the γ pass rates were calculated. Repeated measurements were conducted after scattering blocks were installed. The γ-pass rates were assessed using varying dose criteria.Results:Under various evaluation criteria, no statistically significant differences in γ pass rates were observed between the individual measurements by moving the phantom isocenter and the segmented measurement in the presence of scattering blocks ( P > 0.05). In contrast, there existed statistically significant differences in γ pass rates between the individual measurements by moving the phantom isocenter and the segmented measurement in the absence of scattering blocks according to the (global) criterion of 3%/2 mm absolute dose ( Z = -2.31, P = 0.02). Additionally, the segmented measurement in the presence of scattering blocks enhanced pass rates, with statistical significant difference under the criterion of 3%/2 mm relative dose ( Z = -2.11, P = 0.04). Conclusions:In the case where ArcCheck is used to measure the dose distribution of ultra-long target volumes in cervical cancer, it is advisable to preferentially use individual measurements by moving the phantom isocenter. When segmented measurements combined with merging are required, it is necessary to install scattering blocks during measurements. This will improve γ-pass rates during verification and ensure the accuracy of dose verification.

Objective:Pediatric chronic sinusitis （CRS） is a common disease within the field of otolaryngology-head and neck surgery. Due to the immaturity of sinus development and immune competence in children, its etiology and pathophysiology are complex, and its clinical features and outcomes differ significantly from those in adult patients. Currently, there are issues in the diagnosis and treatment of pediatric CRS, particularly in areas such as antibiotic use and surgical interventions, owing to a lack of sufficient attention. In recognition of this, the Chinese Rhinopathy Research Cooperation Group developed this expert consensus based on a systematic review of the latest literatures from both domestic and international sources, with reference to the latest evidence-based medical evidence worldwide, and in combination with their own clinical experience. The consensus covers various aspects including epidemiology, predisposing factors, pathophysiology, diagnosis and differential diagnosis, as well as treatment strategies such as medical therapy and surgical intervention. It aims to standardize the clinical diagnosis and treatment of pediatric CRS, improve clinical efficacy and patient satisfaction, reduce clinical expenditures, and decrease the occurrence of adverse reactions.
