Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

ObjectiveTo establish a geographical origin identification model for Foeniculi Fructus from Haiyuan， providing a new technical reference for the protection of Haiyuan's geo-authentic medicinal materials and its designation as a national geographical indication agricultural product. MethodsSamples of Foeniculi Fructus were collected from eight producing areas， including Minqin （Gansu）， Bozhou （Anhui）， Qingdao （Shandong）， Dezhou （Shandong）， Urumqi （Xinjiang）， Nujiang （Yunnan）， Gutuo （Inner Mongolia）， and Haiyuan （Ningxia）. Gas chromatography-ion mobility spectrometry （GC-IMS） was used to detect the volatile organic compounds （VOCs） in samples from these geographic origins. VOCs were qualitatively analyzed through dual matching with the National Institute of Standards and Technology （NIST） mass spectral database and the IMS drift time database. Using the Reporter module and Gallery Plot visualization tools within the LAV analytical platform， VOC fingerprint profiles characterizing geographic origins were constructed. A non-targeted analytical strategy was adopted， and 97 VOCs detected via GC-IMS were subjected to principal component analysis （PCA） and partial least squares discriminant analysis （PLS-DA） based on their differential distribution patterns to construct an origin identification model for Foeniculi Fructus from Haiyuan region. Key discriminative markers were screened using variable importance in projection （VIP） values greater than 1. ResultsA total of 97 VOCs were identified， including alcohols， aldehydes， ketones， esters， organic acids， terpenoids， ethers， alkenes， and benzenes. The PLS-DA model， based on VOCs data obtained by GC-IMS， effectively distinguished Foeniculi Fructus in Haiyuan region from those of other origins. During cross-validation， the model achieved a prediction parameter （Q²） of 0.976 and a goodness-of-fit parameter （R²） of 0.936， with no overfitting observed in permutation testing. Twelve key flavor markers with VIP > 1 were identified as characteristic indicators of Haiyuan origin. ConclusionA stable and highly predictive origin identification model for Foeniculi Fructus from Haiyuan was successfully established using GC-IMS technology， PLS-DA， and VIP-based marker screening. This model provides a novel technical strategy for accurately distinguishing Foeniculi Fructus in Haiyuan region from other regional varieties and offers new technical support for its protection as a geo-authentic medicinal material and a nationally designated geographical indication agricultural product in China.

This article reviews relevant literature on the prevention and treatment of cancer with hesperidin published in the past 10 years by searching electronic databases such as China National Knowledge Infrastructure（CNKI）， Wanfang， and PubMed， and summarizes the research progress on the anticancer mechanism of hesperidin. Hesperidin has a wide range of pharmacological effects， including anti-inflammatory， antioxidant， antibacterial， antiviral， anticancer， immune-regulatory， anti-radiation， neuroprotective and cardiovascular protective properties and so on. Its anticancer mechanisms mainly include inhibiting cancer cell proliferation， promoting apoptosis， reducing angiogenesis， inhibiting invasion and migration of cancer cells， regulating immunity and autophagy， and exerting antioxidant and anti-inflammatory effects. As a broad-spectrum anticancer drug， hesperidin manifests chemo-preventive and therapeutic effects across various cancers， contingent upon its multifaceted anticancer mechanisms. Furthermore， this article summarizes the synergistic effects of hesperidin in combination with cisplatin， doxorubicin， cyclophosphamide and paclitaxel. It elucidates that hesperidin can enhance the cytotoxicity of these anticancer drugs against cancer cells while mitigating drug resistance and adverse side effects. Nonetheless， the clinical use is somewhat constrained due to its poor water solubility and limited bioavailability. Therefore， this article also outlines the current strategies for enhancing hesperidin's bioavailability， including structural modification， combination with other chemical substances， and utilization of nano drug carriers.The discovery of derivatives of hesperidin not only preserves the anticancer efficacy of hesperidin, but also effectively overcomes the shortcomings of poor water solubility and low bioavailability of hesperidin, effectively predicting the good application prospects of hesperidin and its derivatives.

Objective To Investigate the cause of a food poisoning incident in a city in Dehong Prefecture， determine the scope of the incident， and to formulate effective prevention and control measures. Methods Field epidemiology and case-control study methods were used to formulate case definition； carry out case search； find suspicious food combined with clinical manifestations， dining history and other information； and collect samples from the suspicious food， cases and environment for laboratory testing. Results A total of 160 cases were found and the incidence rate was 26.02% （160/615）. The main clinical manifestations were diarrhea， leukocytosis， vomiting， nausea and abdominal pain. The average incubation period was 10.89±5.09 h， with 2 h as the shortest and 28 h as the longest. The epidemiological curve suggested the point source exposure mode. The results of case-control study showed that eating roast pork with green shoots was an independent risk factor （OR=13.09， 95%CI： 3.26‒52.54）.16 samples were tested by the local CDC laboratory. Proteus mirabilis was detected in two the anal swabs of two patients He and Chen. Both proteus pani and proteus mirabilis were detected in anal swab of patient Zhou and Proteus pani was detected in roast meat. There was no detection of pathogenic bacteria in other samples. Conclusion Based on the field epidemiological investigation and laboratory test results， we conclude that the food poisoning incident is caused by suspected proteus bacteria. We suggest that the market supervision department should strengthen the supervision of local food hygiene； clarify the sampling rights， responsibilities and technical procedures when medical institutions treat patients with foodborne diseases； ensure finding the causes in time； and take effective prevention and control measures to avoid similar food poisoning events.

Objective:To explore the feasibility and safety of long-distance urological nephrotomy with the support of 5G communication technology by using the domestic robot.Methods:Clinical data of the patients with remote robot-assisted laparoscopic nephrectomy, which were completed from March to April 2021 by the Affiliated Hospital of Qingdao University (as the host hospital where the main operating system located) were retrospectively analyzed. There were 3 patients, including 2 males and 1 female.The average age was 61 (49-73) years, and the average body mass index was 23.73 (20.00-27.76) kg/m 2. One patient had a ASA classification of grade 2, and the other 2 patients had grade 3. All patients met the surgical criteria for non-functional nephrectomy. The chief surgeon who performing the telesurgery was located at the Affiliated Hospital of Qingdao University. The surgeon remotely controlled the bedside operating system (slave system) in 3 local hospitals located in other cities in Shandong Province (network communication distances of 82.5, 141 and 229 km, respectively) by manipulating the master system located in Qingdao. Images and operating instructions during surgery were transmitted using 5G wireless communication technology. Intraoperative network conditions, robot operation, and patient perioperative data were summarized. Results:All 3 tele-nephrectomies were successfully completed. The average network signal latency time was 27.3 (23-30) ms, with no packet loss, and the average total latency time was 177.3(173-180) ms. The mean resection time was 79.3 (52-111) min, and the average intraoperative blood loss was 31.1 (15.6-41.9) ml. There were no network related adverse events occurred during the operation, and the robot-related adverse events occured 3 times, all three of which were characterized by inconsistent master and slave movements of the manipulator arm and the bedside robotic arm. None of these adverse events affected the successful performance of the telesurgery. The mean postoperative exhaust time was 60.5 (38.5-78.0) h. The mean postoperative VAS score at 24 hours was 3.7 (3-4). The Clavien-Dindo classification were all grade I. No significant abnormality was found on the 30th day after surgery, and the patients recovered well at the follow-up until 6 months postoperatively.Conclusions:It is safe and feasible to perform remote robot-assisted laparoscopic nephrectomy based on 5G communication technology with no serious adverse events or surgical complications.However, the conclusion needs to be further verified by large sample and multi-center prospective study.

ObjectiveTo explore the effective components， targets， and mechanism of Houttuynia cordata against lung cancer by means of systems pharmacology and further to provide a reference for the further development and clinical application of this medicinal. MethodChemical components of H. cordata were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the active components were screened based on oral bioavailability （OB） and drug-likeness （DL）. Then the potential targets were predicted， followed by enrichment analysis. Finally， sodium houttuyfonate （SH） was selected for verifying the anti-tumor mechanism. Cell counting kit-8 （CCK-8） assay was used to evaluate the effect of SH on the in vitro proliferation of two lung cancer cell lines： A549 and LLC， and the regulation of tumor-related proteins by SH was verified by Western blot. ResultA total of 7 active compounds and 352 targets of the active components were screened out. According to the enrichment analysis of targets， H. cordata had potential therapeutic effects on cancer. SH had inhibitory effect on both A549 and LLC. Western blot results showed that G₁/S-specific Cyclin D₁， E₁ and cyclin-dependent kinase （CDK）2， CDK4 all tended to be down-regulated， and Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） also changed significantly. ConclusionH. cordata has the potential anti-tumor effects by arresting the tumor cells in the G₁ phase through the JAK2/STAT3 pathway.

To analyze the endoscopic ultrasonography (EUS) and histopathological features of esophageal epithelial malignant tumors misdiagnosed as esophageal submucosal tumors (SMT), data of patients diagnosed as having esophageal SMT preoperatively but confirmed as esophageal epithelial malignant tumor by pathology after operation in Nanjing Drum Tower Hospital from January 2012 to December 2020 were retrospectively analyzed, and the clinical data including age, gender, size and location of the lesion, origin and echo of the lesion under EUS, endoscopic treatment and postoperative pathology were recorded. Among the 11 patients, there were 9 males and 2 females, aged (65.5±6.2) years. The length diameter of 9 lesions was ≤2 cm, and 8 lesions were located in the middle thoracic esophagus. Among the 11 patients, 10 underwent EUS before operation. The lesions originated from submucosa in 6 cases, muscularis propria in 2 cases and muscularis mucosa in 2 cases. The echo of the lesions was hypoechoic in 9 cases and isoechoic in only 1 case. Of the 11 patients, 3 underwent endoscopic mucosal resection, 6 underwent endoscopic submucosal dissection, and 2 underwent submucosal tunneling endoscopic resection. The histopathological types included 3 cases of moderately to poorly differentiated squamous cell carcinoma, 3 cases of basaloid squamous cell carcinoma, 2 cases of adenoid cystic carcinoma (including 1 case of adenoid cystic carcinoma colliding with squamous cell carcinoma), 2 cases of adenocarcinoma, and 1 case of esophageal sarcomatoid carcinoma with basaloid squamous cell carcinoma. Endoscopic manifestations of submucosal eminence in esophageal epithelial malignant tumors are extremely rare. EUS is helpful for differential diagnosis, and diagnostic treatment can make a definite diagnosis.
