OBJECTIVEThis study aimed to compare the treatment effects of simultaneous surgical treatment and stage operation for patients with craniomaxillofacial fracture combined with other injuries.
METHODSFifty patients with maxillofacial fractures combined with other injuries were chosen and divided into simultaneous (28 patients) and staging (22 patients) operation groups. In simultaneous operation group, maxillofacial fracture reduction, internal fixation, and other parts of the surgery were simultaneously operated by relevant departments jointly. In the staging operation group, maxillofacial fracture reduction and internal fixation were performed after treatment of other injuries. Data on the treatment efficacy and associated injuries of the two groups were statistically analyzed.
RESULTSIn the simultaneous operation group, 26 patients had good occluding relation, the maximum mouth opening was (34.5 +/- 3.7) mm, the symmetry and shape of hard tissues recovered well, and the bone plate of one patient was removed because of internal fixation infection. In the staging operation group, 14 patients had good occluding relation, the maximum mouth opening was (28.5 +/- 3.5) mm, the symmetry and shape of hard tissues poorly recovered, and the bone plates of 5 patients were removed because of internal fixation infection. Statistical significance was determined among occluding relation, maximum mouth opening, postoperative complications, and length of stay of the two groups (P< 0.05). Treatment of the simultaneous operation group was more effective than that of the staging operation group.
CONCLUSIONWhen a patient's condition is relatively stable, simultaneous surgical treatment of multiple specialties should be conducted to treat craniomaxillofacial fracture combined with other injuries.

This study was aimed to investigate the effect of visceral pain and water metabolism on irritable bowel syndrome with diarrhea (IBS-D) model rats by moxibustion and its products. A total of 40 SD rats were randomly di-vided into the normal group, model group, moxibustion group, non-smoke moxibustion group, and moxa smoke group. IBS-D model was induced by colorectal distension with an inflatable balloon. The general condition of rats was ob-served. Visceral pain was assessed by abdominal withdrawal reflex (AWR) scores. The immunohistochemical method was used in the detection of claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expression. The results showed that compared with the normal group, the AWR scores, claudin-1, AQP3, AQP8 and Na+/K+-ATPase protein expres-sion in the colon were decreased in the model group (P < 0.01). The stool was loose, which was on hair around the anus. After moxibustion, non-smoke moxibustion and moxa smoke stimulation, the stool conditions of IBS-D model rats were improved. The AWR scores were decreased in different degrees (P < 0.05 or P < 0.01). Except Na+/K+-ATPase, expressions of claudin-1, AQP3 and AQP8 in colon were increased in different degrees (P < 0.05 or P <0.01). The comprehensive therapeutic effect showed that moxibustion was better than non-smoke moxibustion; and non-smoke moxibustion was better than moxa smoke stimulation. It was concluded that the combination of warm stimulation, optical radiation and moxa smoke induced best effect in improving visceral pain and water metabolism on IBS-D model rats. Among them, warm stimulation and optical radiation may play the main role.

Objectives To explore the preventive and therapeutic effects of Jianpi Yiqi Shexue Keli ( Spleen-fortifying Qi-tonifyingHemostatic Granule, JPYQSXKL) and its disassembled prescriptions ( Jianpi Granules) in the treatment of zebrafish cerebral hemorrhage induced by simvastatin. Methods 660 mela-nin alleles mutant Albino zebrafishes were randomly divided into normal control group, model group, Jianpi groups ( A, B, C, D) and subgroups of their different concentration (100 μg/mL, 250 μg/mL, 500 μg/mL, 750 μg/mL, and 1000 μg/mL) ( n=30 in each group) . Blinding measures were strictly followed throughout the process. The model of intracranial hemorrhage was established by adding 0. 5μM simvastatin while administering granules of different concentration at the same time. 24 hours later, 20 fi-shes out of each group were observed under the microscope to count the number of hemorrhagic fishes ( S) and thus calculate hemorrhage percentage and its decrease rate. Results ①The incidence rate of hemorrhage in Jianpi groups (100 μg/mL, 250 μg/mL, 500 μg/mL and 750 μg/mL) was 75%, 70%, 60% and 70%;②The incidence rate of hemorrhage in Jianpi Yiqi groups (100 μg/mL, 250 μg/mL and 500 μg/mL) were 60%, 40% and 85%; ③The incidence rate of hemorrhage in Jianpi Yiqi Shengxue (Spleen-fortifying Qi-tonifying Blood-nourishing) groups (100 μg/mL and 250 μg/mL)were 50% and 45%;④The incidence rate of hemorrhage in Jianpi Yiqi Shexue groups(100 μg/mL, 250 μg/mL and 500 μg/mL) were 35%, 25% and 45%. Conclusions No protective effects of Jianpi granule and Jianpi Yiqi granule on intracranial hemorrhage induced by simvastatin in zebrafish were observed. Jianpi Yiqi Shengxue granule and Jianpi Yiqi Shexue granule appeared to have a good effect yet high dose was toxic.

BACKGROUND:
Cutaneous wound healing represents a common fundamental phenomenon requiring the participation of cells of distinct types and a major concern for the public. Evidence has confirmed that photobiomodulation (PBM) using near-infrared (NIR) can promote wound healing, but the cells involved and the precise molecular mechanisms remain elusive.
METHODS:
Full-thickness skin defects with a diameter of 1.0 cm were made on the back of rats and randomly divided into the control group, 10 J, 15 J, and 30 J groups. The wound healing rate at days 4, 8, and 12 postoperatively was measured. HE and Masson staining was conducted to reveal the histological characteristics. Immunofluorescence staining was performed to label the epidermal stem cells (ESCs) and hair follicle stem cells (HFSCs). Western blot was performed to detect the expressions of proteins associated with ESCs and HFSCs. Cutaneous wound tissues were collected for RNA sequencing. Gene ontology and the Kyoto Encyclopedia of Genes and Genomes analysis was performed, and the hub genes were identified using CytoHubba and validated by qRT-PCR.
RESULTS:
PBM can promote reepithelialization, extracellular matrix deposition, and wound healing, increase the number of KRT14+/PCNA+ ESCs and KRT15+/PCNA+ HFSCs, and upregulate the protein expression of P63, Krt14, and PCNA. Three hundred and sixty-six differentially expressed genes (DEGs) and 7 hub genes including Sox9, Krt5, Epcam, Cdh1, Cdh3, Dsp, and Pkp3 were identified. These DEGs are enriched in skin development, cell junction, and cadherin binding involved in cell–cell adhesion etc., while these hub genes are related to skin derived stem cells and cell adhesion.
CONCLUSION
PBM accelerates wound healing by enhancing reepithelialization through promoting ESCs and HFSCs proliferation and elevating the expression of genes associated with stem cells and cell adhesion. This may provide a valuable alternative strategy to promote wound healing and reepithelialization by modulating the proliferation of skin derived stem cells and regulating genes related to cell adhesion.

Objective:To clarify the clinicopathological features, prognosis, and recurrence pattern of early-onset gastric cancer (EOGC).Methods:Using data from the gastric cancer database of Zhongshan Hospital, Fudan University, we performed a retrospective, large-scale, real-world study of 5046 patients with gastric cancer who had undergone redical or palliative gastrectomy from January 2013 to December 2018, including 425 patients with EOGC (age ≤45 years) and 4621 controls. All those patients were pathologically confirmed adenocarcinoma with complete follow-up of five years. Residue gastric cancer and patients without complete clinical or follow-up data were excluded. We used a combination of outpatient and telephone follow-up, ending in October 2022 (median duration of follow-up 60 months), and compared the clinicopathological features and prognosis of the two groups.Results:The clinicopathological features of EOGC included female predominance (61.1% [262/425 vs. 26.3% [1217/4621], χ 2=234.215, P<0.001), fewer comorbidities (31.3% [133/425] vs. 58.5% [2703/4621], χ 2=34.378, P<0.001), poorer differentiation (90.6% [385/425] vs. 78.2% [3614/4621], χ 2=30.642, P<0.001), higher proportion of diffuse type (53.9% [229/425] vs. 18.3% [846/4621], χ 2=274.474, P<0.001), higher proportion of T4 stage (44.7% [190/425] vs. 37.5% [1733/4621], χ 2=17.535, P=0.001), more lymph node metastases (60.5% [257/425] vs. 53.9% [2491/4621], χ 2=6.764, P=0.009), and higher proportion of pathological stage III/IV (47.5% [202/425] vs. 42.4% [1959/4621], χ 2=4.093, P=0.043). The 5-year overall survival rates of the EOGC and control groups were 55.1% and 49.1%, respectively. Overall survival was significantly better in the EOGC than in the control group ( P<0.001). According to subgroup analysis, the prognosis of pathological stage I/II/III EOGC was better than that of the control group. Recurrence rates were similar in the two groups, whereas patients with EOGC had a higher proportion of peritoneal recurrence (7.8% [33/425] vs. 3.2% [146/4621], χ 2=23.741, P<0.001) and a lower proportion of distant metastasis (4.9% [21/425] vs. 8.3% [385/4621], χ 2=6.247, P=0.012). Conclusion:EOGC has unique clinicopathological features and recurrence patterns and resectable EOGC has a better prognosis, suggesting that patients with EOGC should be actively treated with the focus on preventing peritoneal recurrence.
