Objective:To evaluate the clinical utility of an intelligent endoscope transportation system in the digestive endoscopy center.Methods:A parallel-group controlled trial was conducted at Digestive Endoscopy Center of Qilu Hospital of Shandong University from June 1st to December 31st 2024, comparing robotic intelligent endoscope transport (experimental group) versus manual transport (control group). Performance metrics, including response time, transportation speed, labor efficiency, contamination prevention, closed-loop traceability, and nursing staff satisfaction, were statistically analyzed. Full-time equivalent (FTE) was introduced to quantify the operational efficiency of the experimental group.Results:The study included a total of 60 206 instances of intelligent endoscope transportation and 60 485 instances of manual transportation data. The robotic group demonstrated significantly shorter response times versus manual group for initial dispatch (51.08±14.97 seconds VS 54.44±13.61 seconds, t=35.8, P<0.001) and recovery response time (32.52±11.26 seconds VS 40.20±11.40 seconds, t=103.93, P<0.001). During the 148 days operational period, the success rate was 99.83% (60 104/60 206) and the failure rate was 0.17% (102/60 206) for robotic transports. Primary failure causes were wireless disconnection, pathfinding errors, and mechanical faults, averaging 1.05 malfunctions/month with no adverse events. The success and failure rate was 99.26% (60 043/60 485) and 0.74% (442/60 485) respectively for manual transports. Staff satisfaction was significantly higher for robotic transport in endoscopic transportation (4.65±0.55 scores VS 3.97±0.98 scores, t=96.5, P<0.001) and delivery process (4.71±0.59 scores VS 3.90±1.04 scores, t=210.3, P<0.001). and workload intensity was significantly lower (4.06±0.77 scores VS 4.48±0.63 scores, t=59.9, P=0.025). The system reduced labor requirements by 3.68 FTE, yielding annual savings of ¥657 000. Conclusion:The robotic intelligent endoscope transport system improves work efficiency, reduces nursing labor costs and physical workload, enhances job experience and satisfaction, and enables full-process smart traceability, providing a validated solution for endoscopy center logistics.

OBJECTIVE:
To compare the efficacy of the fourth-generation minimally invasive technique-minimally invasive extra-articular metaphyseal distal transverse osteotomy (META) and Chevron osteotomy in treatment of hallux valgus.
METHODS:
A total of 80 patients with hallux valgus, who underwent single-foot surgery between July 2023 and January 2025 and met the inclusion criteria, were included in the study. Among them, 40 patients were treated with META and 40 with Chevron osteotomy. There was no significant difference in baseline data between the two groups ( P>0.05), including gender, age, height, weight, body mass index, disease duration, lesion site, hallux valgus deformity degree, as well as preoperative scores of each item (pain, function, alignment, total score) in the American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Joint Scale (AOFAS-Hallux-MTP-IP), scores of each item (pain, walking/standing, social interaction, total score) in the Manchester-Oxford Foot Questionnaire (MOXFQ), hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), sesamoid position, and the 1st metatarsal head morphology. The postoperative AOFAS-Hallux-MTP-IP scores, MOXFQ scores, as well as HVA, IMA, DMAA, the 1st metatarsal head morphology, and sesamoid position measured based on weight-bearing foot X-ray films were compared between the two groups; the occurrence of postoperative complications was recorded.
RESULTS:
All patients in both groups were followed up 6-18 months, and there was no significant difference in the follow-up time between the two groups ( P>0.05). At last follow-up, the scores of all items in AOFAS-Hallux-MTP-IP in both groups were higher than those before operation, and the scores of all items in MOXFQ were lower than those before operation, with significant differences ( P<0.05); there was no significant difference in the change values of all items in MOXFQ between the two groups ( P>0.05). The change value in AOFAS function score in the META group was significantly higher than that in the Chevron osteotomy group ( P<0.05), while there was no significant difference in the change value of AOFAS pain score, alignment score, and total score between the two groups ( P>0.05). After operation, 1 case (2.5%) of superficial incision infection and 2 cases (5.0%) of numbness around the incision occurred in the Chevron osteotomy group, while only 2 cases (5.0%) of numbness around the incision occurred in the META group. Imaging reexamination showed that HVA, IMA, and DMAA in both groups were signifncatly smaller than those before operation ( P<0.05), and there was no significant difference in the change values of the above angles between the two groups ( P>0.05). The 1st metatarsal head morphology and sesamoid position in the META group were better than those in the Chevron osteotomy group after operation, with significant differences ( P<0.05).
CONCLUSION
Both META and Chevron osteotomy can correct hallux valgus deformity, improve foot function, and relieve pain, but META has more advantages in correcting metatarsal rotation and reducing dislocated sesamoids.

Objective To establish a weightlessness simulation animal model using miniature pigs, leveraging the characteristic of multiple systems’ tissue structures and functions similar to those of humans, and to observe pathophysiological changes, providing a new method for aerospace research. Methods Nine standard-grade miniature pigs were selected and randomly divided into an experimental group (n=7) and a control group (n=2). The experimental group was fixed using customized metal cages, with canvas slings suspending their hind limbs off the ground, and the body positioned at a -20° angle relative to the ground to simulate unloading for 30 days (24 hours a day). Data on body weight, blood volume, and blood biochemistry indicators were collected at different time points for statistical analysis of basic physiological changes. After the experiment, the miniature pigs were euthanized and tissue samples were collected for histopathological observation of the cardiovascular, skeletal and muscle systems HE and Masson staining. Statistical analysis was also conducted on the thickness of arterial vessels and the diameter of skeletal muscle fibers. Additionally, western blotting was employed to detect the expression levels of skeletal muscle atrophy-related proteins, including muscle-specific RING finger protein 1 (MuRf-1) and muscle atrophy F-box (MAFbx, as known as Atrogin-1), while immunohistochemistry was used to detect the expression of glial fibrillary acidic protein (GFAP), an indicator of astrocyte activation in the brain, reflecting the pathophysiological functional changes across systems. Results After hindlimb unloading, the experimental group showed significant decreases in body weight (P<0.001) and blood volume (P<0.01). During the experiment, hemoglobin, hematocrit, and red blood cell count levels significantly decreased (P<0.05) but gradually recovered. The expression levels of alanine aminotransferase and γ-glutamyltransferase initially decreased (P<0.05) before rebounding, while albumin significantly decreased (P<0.001) and globulin significantly increased (P<0.01). Creatinine significantly decreased (P<0.05). The average diameter of gastrocnemius muscle fibers in the experimental group significantly shortened (P<0.05), with a leftward shift in the distribution of muscle fiber diameters and an increase in small-diameter muscle fibers. Simultaneously, Atrogin-1 expression in the gastrocnemius and paravertebral muscles significantly increased (P<0.05). These changes are generally consistent with the effects of weightlessness on humans and animals in space. Furthermore, degenerative changes were observed in some neurons of the cortical parietal lobe, frontal lobe, and hippocampal regions of the experimental group, with a slight reduction in the number of Purkinje cells in the cerebellar region, and a significant enhancement of GFAP-positive signals in the hippocampal area (P<0.05). Conclusion Miniature pigs subjected to a -20° angle hind limb unloading for 30 days maybe serve as a new animal model for simulating weightlessness, applicable to related aerospace research.

Pheretima,also called"earthworms",is a well-known animal-derived traditional Chinese medicine that is extensively used in over 50 Chinese patent medicines(CPMs)in Chinese Pharmacopoeia(2020 edi-tion).However,its zoological origin is unclear,both in the herbal market and CPMs.In this study,a strategy for integrating in-house annotated protein databases constructed from close evolutionary relationship-sourced RNA sequencing data from public archival resources and various sequencing al-gorithms(restricted search,open search,and de novo)was developed to characterize the phenotype of natural peptides of three major commercial species of Pheretima,including Pheretima aspergillum(PA),Pheretima vulgaris(PV),and Metaphire magna(MM).We identified 10,477 natural peptides in the PA,7,451 in PV,and 5,896 in MM samples.Five specific signature peptides were screened and then validated using synthetic peptides;these demonstrated robust specificity for the authentication of PA,PV,and MM.Finally,all marker peptides were successfully applied to identify the zoological origins of Brain Heart capsules and Xiaohuoluo pills,revealing the inconsistent Pheretima species used in these CPMs.In conclusion,our integrated strategy could be used for the in-depth characterization of natural peptides of other animal-derived traditional Chinese medicines,especially non-model species with poorly annotated protein databases.

In unicompartmental replacement surgery, there are a wide variety of commercially available unicompartmental prostheses, and the consistency of the contact surface between the common liner and the femoral prosthesis could impact the stress distribution in the knee after replacement in different ways. Medial tibial plateau fracture and liner dislocation are two common forms of failure after unicompartmental replacement. One of the reasons is the mismatch in the mounting position of the unicompartmental prosthesis in the knee joint, which may lead to failure. Therefore, this paper focuses on the influence of the shape of the contact surface between the liner and the femoral prosthesis and the mounting position of the unicompartmental prosthesis on the stress distribution in the knee joint after replacement. Firstly, a finite element model of the normal human knee joint was established, and the validity of the model was verified by both stress and displacement. Secondly, two different shapes of padded knee prosthesis models (type A and type B) were developed to simulate and analyze the stress distribution in the knee joint under single-leg stance with five internal or external rotation mounting positions of the two pads. The results showed that under a 1 kN axial load, the peak contact pressure of the liner, the peak ACL equivalent force, and the peak contact pressure of the lateral meniscus were smaller for type A than for type B. The liner displacement, peak contact pressure of the liner, peak tibial equivalent force, and peak ACL equivalent force were the smallest for type A at 3° of internal rotation in all five internal or external rotation mounting positions. For unicompartmental replacement, it is recommended that the choice of type A or type B liner for prosthetic internal rotation up to 6° should be combined with other factors of the patient for comprehensive analysis. In conclusion, the results of this paper may reduce the risk of liner dislocation and medial tibial plateau fracture after unicompartmental replacement, providing a biomechanical reference for unicompartmental prosthesis design.

Objective:To investigate the current status and related influencing factors of blood uric acid levels of active-duty sailors.Methods:A total of 538 active-duty male sailors who received physical examination in a level-3 Grade A hospital in an island of Zhejiang Province from July 2019 to June 2020 were selected according to the random number table method. The results of laboratory examination, ultrasound examinations of abdomen and urinary system, and anthropometric exam were collected. Questionnaires on behavioral habits were also conducted. Single factor χ 2 test, Pearson correlation, and Logistic regression were used to analyze the influencing factors of hyperuricemia in male sailors on active duty. Results:The average blood uric acid level of male sailors was (361.63±74.39) μmol/L, and the prevalence of hyperuricemia was 17.66%. Fatty liver or intrahepatic fat ( OR=3.448, 95% CI=2.064-5.763, P<0.001), and blood creatinine level ( OR=1.075, 95% CI=1.046-1.105, P<0.001) are the risk factors for hyperuricemia in active-duty male sailors; and the average daily water drinking ≥2 000 ml ( OR=0.331, 95% CI=0.154-0.711, P<0.01), the average daily fruit and vegetable intake ≥500 g ( OR=0.509, 95% CI=0.308-0.842, P<0.01), college education or above ( OR=0.538, 95% CI=0.327-0.885, P<0.05), and medium labor intensity or above ( OR=0.583, 95% CI=0.350-0.972, P<0.05) are the protective factors of hyperuricemia in active-duty male sailors. Conclusion:When delivering health education for sailors, it is necessary to instruct them to drink more water, eat more fresh fruits and vegetables, maintain appropriate labor intensity, control the incidence of fatty liver or intrahepatic fat, and reduce the prevalence of hyperuricemia. Thus, these will eventually improve the overall health of sailors.

Solar energy, which is essential for the origin and evolution of all life forms on Earth, can be objectively recorded through attributes such as climatic ambient temperature (CAT), ultraviolet radiation (UVR), and sunlight duration (SD). These attributes have specific geographical variations and may cause different adaptation traits. However, the adaptation profile of each attribute and the selective role of solar energy as a whole during human evolution remain elusive. Here, we performed a genome-wide adaptation study with respect to CAT, UVR, and SD using the Human Genome Diversity Project-Centre Etude Polymorphism Humain (HGDP-CEPH) panel data. We singled out CAT as the most important driving force with the highest number of adaptive loci (6 SNPs at the genome-wide 1 × 10-7 level;401 at the suggestive 1 × 10-5 level). Five of the six genome-wide significant adaptation SNPs were successfully replicated in an independent Chinese population (N = 1395). The corresponding 316 CAT adaptation genes were mostly involved in development and immunity. In addition, 265 (84%) genes were related to at least one genome-wide associationstudy (GWAS)-mapped human trait, being significantly enriched in anthropometric loci such as those associated with body mass index (x2;P<0.005), immunity, metabolic syndrome, and cancer (x2;P<0.05). For these adaptive SNPs, balancing selection was evident in Euro-Asians, whereas obvious positive and/or purifying selection was observed in Africans. Taken together, our study indicates that CAT is the most important attribute of solar energy that has driven genetic adaptation in development and immunity among global human populations. It also supports the non-neutral hypothesis for the origin of disease-predisposition alleles in common diseases.
