Among the 9 constitutions, 102 people (22.32%) had a peaceful constitution, while 355 people (77.68%) had a biased constitution; the top three biased constitutions were qi stagnation constitution 90 people (19.69%), yang deficiency constitution 83 people (18.16%), and phlegm-dampness constitution 56 people (12.25%). The factors that influenced physical constitutions according to the severity of lifestyle were: sleep, diet, mood, exercise, labor, environment, children, and education.Conclusions:Female medical workers have a high proportion of biased constitution, and the main types of biased constitution are qi stagnation constitution, yang deficiency constitution, and phlegm-dampness constitution. According to the existing biased constitution, targeted adjustments and interventions are carried out, and it is of great significance to protect and care for the health of female medical workers from the concept of preventive treatment of diseases with TCM.

The differentiation between benign and malignant thyroid nodules is pivotal in clinical practice. However, current diagnostic systems face challenges, such as heterogeneity in ultrasound interpretation, the invasiveness of fine-needle aspiration cytology and indeterminate of results. Artificial intelligence (AI) has evolved from traditional machine learning to deep learning, enabling advances in image recognition, feature extraction, and multimodal data integration. Nevertheless, AI applications remain constrained by limitations, including the insufficiency of high-quality annotated data and inadequate cross-center generalizability. Future progress will focus on algorithm refinement, multimodal data fusion, and multicenter clinical validation to enhance model generalizability and diagnostic accuracy.

Objective:To investigate the changes of artemin protein expression in diabetic peripheral neuropathy (DPN) and to explore the regulatory effect of human adipose-derived stem cell (ADSC) exosomes on the change of artemin protein expression.Methods:This research was a prospective observational clinical research combined with experimental research. Thirteen DPN patients (9 males and 4 females, aged 32 to 68 years) who were admitted to the First Affiliated Hospital of Air Force Medical University (hereinafter referred to as our hospital) from May 2022 to October 2023 and met the inclusion criteria were selected as DPN group, and 5 non-diabetes patients (4 males and 1 female, aged 29 to 61 years) who were admitted to our hospital in the same period of time and met the inclusion criteria were selected as control group. The toe nerve or sural nerve tissue in the abandoned tissue after debridement or amputation of patients in the two groups was collected. The pathological changes of nerve tissue were observed after hematoxylin-eosin staining; the protein expressions of S100β and artemin in nerve tissue were observed after immunofluorescence staining, and the artemin protein expression was quantified; the protein and mRNA expressions of artemin were detected by Western blotting and real-time fluorescent quantitative reverse transcription polymerase chain reaction, respectively (the sample number in DPN group and control group was 13 and 5, respectively). Twelve male C57BL/6 mice aged 3 to 5 days were collected to isolate Schwann cells, and the cells were divided into conventional culture group cultured routinely, high glucose alone group (cultured with high concentration of glucose solution only), and high glucose+exosome group (cultured with high concentration of glucose solution and extracted human ADSC exosomes). After 24 hours of culture, the cell proliferation activity was detected by cell counting kit 8 ( n=6). After 48 hours of culture, the protein expression of artemin was detected by Western blotting ( n=3). Results:Compared with those in control group, the neural supporting cells decreased and the inflammatory cells increased in the nerve tissue of patients in DPN group, showing typical manifestations of nerve injury. Immunofluorescence staining showed that compared with those in control group, the nuclei was more, and the protein expression of S100β was lower in nerve tissue of patients in DPN group. The protein expression of artemin in nerve tissue of patients in DPN group was 71±31, which was significantly lower than 1 729±62 in control group ( t=76.92, P<0.05). Western blotting detection showed that the protein expression of artemin in nerve tissue of patients in DPN group was 0.74±0.08, which was significantly lower than 0.97±0.06 in control group ( t=5.49, P<0.05). The artemin mRNA expression in nerve tissue of patients in DPN group was significantly lower than that in control group ( t=7.65, P<0.05). After 24 hours of culture, compared with that in conventional culture group, the proliferation activities of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the proliferation activity of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). After 48 hours of culture, compared with those in conventional culture group, the protein expressions of artemin of Schwann cells in high glucose alone group and high glucose+exosome group were significantly decreased ( P<0.05); compared with that in high glucose alone group, the protein expression of artemin of Schwann cells in high glucose+exosome group was significantly increased ( P<0.05). Conclusions:The protein expression of artemin in nerve tissue of DPN patients is lower than that in normal nerve tissue, which may be related to the reduction of proliferation activity of Schwann cells by high glucose. Human ADSC exosomes may improve the proliferation activity of Schwann cells by increasing artemin protein expression, thereby delaying the progression of DPN.

Objective:To explore the influence and its mechanism of allogeneic dermal papilla cells (DPCs) on the wound healing of full-thickness skin defects in mice.Methods:This study was an experimental study. DPCs were isolated from the whisker follicles of five 6-week-old male C57BL/6J mice by combining microdissection with collagenase digestion and were successfully identified. Eighteen 8-week-old male C57BL/6J mice were divided into phosphate buffer solution (PBS) group and DPC group according to the random number table, with 9 mice in each group, and the full-thickness skin defect wound model was created on the back of all mice. On day 2, 4, and 6 after injury, the mice in DPC group were administered 100 μL of cell suspension containing 1×10 6 DPCs of the 4 th passage by subcutaneous injection around the wound, and the mice in PBS group was administered an equal volume of PBS. On day 3, 7, 10, and 14 after injury, the wound healing and hair growth of mice in two groups were observed, and the residual wound area was measured, and the hair coverage area on the wound of mice in two groups was measured on day 14 after injury. On day 14 after injury, the wound tissue samples of mice in two groups were collected. Hematoxylin-eosin staining was performed to observe the condition of newborn hair follicles and the number was counted, Masson staining was performed to observe the collagen deposition in the dermis and the collagen deposition area was measured, the immunofluorescence method was used to detect the protein expressions of Wnt/β-catenin signaling pathway related molecules β-catenin and lymphoid enhancer binding factor 1 (Lef1), and Western blotting and real-time fluorescence quantitative reverse transcription polymerase chain reaction were used to detect the protein and mRNA expressions of β-catenin and Lef1, respectively. The number of samples in each experiment was 3. Results:Compared with those in PBS group, the mice in DPC group had accelerated wound re-epithelialization at each time point after injury, and more hair growth on day 10 and 14 after injury. On day 7, 10, and 14 after injury, the residual wound areas of mice in DPC group were (13.92±2.90), (3.69±1.78), and (1.09±0.14) mm 2, respectively, which were significantly smaller than (26.19±2.06), (10.84±3.59), and (6.75±2.11) mm 2 in PBS group, respectively (with t values of 5.85, 3.09, and 4.63, respectively, P values all <0.05). On day 14 after injury, the hair coverage area on the wound of mice in DPC group was (62±7) mm 2, which was significantly larger than (35±6) mm 2 in PBS group ( t=2.89, P<0.05). On day 14 after injury, compared with those in PBS group, the number of newborn hair follicles in the wound tissue of mice in DPC group was significantly increased ( t=5.43, P<0.05), and the dermal collagen deposition area was significantly reduced ( t=3.56, P<0.05). On day 14 after injury, both the immunofluorescence method and the Western blotting detection showed that the protein expressions of β-catenin (with t values of 5.49 and 4.25, respectively, P values all <0.05) and Lef1 (with t values of 7.50 and 11.54, respectively, P values all <0.05) in the wound tissue of mice in DPC group were significantly higher than those in PBS group; the mRNA expressions of β-catenin and Lef1 in the wound tissue of mice in DPC group were significantly higher than those in PBS group (with t values of 7.68 and 9.67, respectively, P<0.05). Conclusions:DPCs can accelerate the re-epithelialization of full-thickness skin defect wounds in mice by activating Wnt/β-catenin signaling pathway and promote hair follicle regeneration during the process of wound healing.

Objective: To investigate the pathological changes and conduct viral gene analysis of OPA and MVD co-occurrence in Inner Mongolia, China. Methods: Using gross pathology, histopathology, immunohistochemistry, ultrastructural pathology, PCR, and sequence analysis, we investigated the concurrent infection of JSRV and MVV in 319 Dorper rams slaughtered in a private slaughterhouse in Inner Mongolia, in 2022. Results: Of the 319 rams included, 3 showed concurrent JSRV and MVV infection. Gross lung pathology showed diffuse enlargement, consolidation, and greyish-white miliary nodules on the lung surface; the trachea was filled with a white foamy fluid; hilar and mediastinal lymph nodes were significantly enlarged. Histopathology results revealed typical OPA and MVD lesions in the lung tissue. Immunohistochemical results were positive for JSRV envelope protein (Env) in the tumor cells and MVV CA in alveolar macrophages. Transmission electron microscopy showed several virions and autophagosomes in the lung tissue, severely damaged mitochondria, and the induced mitophagy. Nucleotide sequences obtained for JSRV env and MVV gag showed the highest homology with the Inner Mongolian strains of JSRV env (JQ837489) and MVV gag (MW248464). Conclusions and Relevance: Our study confirmed that OPA and MVD co-occurrence and identified the pathological changes in Inner Mongolia, China, thereby providing references for the identification of concurrent JSRV and MVV infections.

Objective:To explore the short-term efficacy of perioperative fecal microbiota transplantation combined with nutritional support in patients with radiation-induced enteritis complicated by intestinal obstruction.Methods:The cohort of this prospective cohort study comprised 45 patients (nine men and 36 women) with radiation-induced enteritis complicated by intestinal obstruction admitted to Shanghai Tenth People's Hospital Affiliated to Tongji University from January 2022 to October 2022. The median age was 53 (42–65) years. Thirty-five of the patients had gynecological tumors and 10 colorectal malignancies. The patients were randomly allocated to a fecal microbiota transplantation group of 20 patients who underwent fecal microbiota transplantation starting 2 weeks before surgery for 6 days, in addition to receiving conventional perioperative treatment, and a conventional treatment group of 25 patients who only received nutritional support during the perioperative period. There were no significant differences in baseline characteristics (sex, age, preoperative nutritional indices, and surgical procedure) between the two groups (all P>0.05). Postoperative recovery (time to passing flatus or a bowel movement, length of stay) and complications were compared between the two groups. Postoperative complications within 30 days after surgery classified in accordance with the international Clavien–Dindo classification of surgical complications (I–V) were statistically analyzed. Improvement in gastrointestinal symptoms, namely abdominal pain, distension, diarrhea, and rectal bleeding) and gastrointestinal quality of life scores (which include 36 problems rated 0–144 points related to physical, psychological, social activities and family life; the lower the score, the more severe the symptoms) were compared between the two groups. Nutritional recovery was assessed by body mass, body mass index, total protein, albumin, prealbumin, and hemoglobin. Results:Compared with the conventional treatment group, the postoperative hospital stay was shorter in the fecal microbiota transplantation group (8.0±4.3 days vs. 11.2±5.4 days, t=2.157, P=0.037) and the time to passage of flatus or having a bowel movement was earlier (2.2±3.2 days vs. 3.9±2.3 days, t=2.072, P=0.044). There were 26 postoperative complications in the fecal microbiota transplantation group and 59 in the conventional treatment group. There were 20 and 36 Grade I to II complications and no and three Grade III to V complications in the transplantation and conventional treatment group, respectively. The overall grade of complication did not differ significantly between the two groups ( P=0.544). However, the incidence of postoperative intestinal inflammatory obstruction was lower in the fecal microbiota transplantation than the conventional treatment group (10.0% [2/20] vs. 40.0% [10/25], P=0.040). One patient in the conventional treatment group died. This patient had complete intestinal obstruction complicated by severe malnutrition preoperatively, and an intestinal fistula complicated by abdominal infection postoperatively, and died despite active treatment. Nineteen and 23 patients in the transplantation and conventional treatment group, respectively, attended for follow-up 1 month after surgery; 19 and 21, respectively, attended for follow-up 3 months after surgery, and 17 and 20, respectively, attended for follow-up 6 months after surgery. There were no significant differences between the two groups in abdominal pain or rectal bleeding 1, 3, or 6 months after surgery (all P>0.05). One month after surgery, the incidence of abdominal distension and diarrhea was lower in the fecal microbiota transplantation than in the conventional treatment group (3/19 vs. 48.0% [11/23], P=0.048; 3/19 vs. 52.2% [12/23], P=0.023). However, at the 3 and 6 month follow-ups the incidence of abdominal distension and diarrhea had gradually decreased in both groups and the differences between the groups were not statistically significant ( P>0.05 for all). Scores for gastrointestinal quality of life improved significantly in both treatment groups compared with preoperative values ( F=71.250, P<0.001; F=79.130, P<0.001, respectively). Scores for gastrointestinal quality of life were higher in the fecal microbiota transplantation than the conventional treatment group at all follow-up time points ( P<0.05). One-way ANOVA showed that body mass, body mass index, and total protein, albumin and hemoglobin concentrations improved in both groups compared with preoperative values (all P<0.05). Prealbumin concentration improved significantly in the transplantation ( F=5.514, P=0.002), but not in the conventional, group ( F=1.535, P=0.211). The improvements in body mass, body mass index, total protein, and albumin were better in the fecal microbiota transplantation than conventional treatment group at 3 and 6 months of follow-up (all P<0.05). Conclusion:Perioperative fecal microbiota transplantation combined with nutritional support is effective in improving early postoperative nutritional status and quality of life in patients with radiation-induced enteritis complicated by intestinal obstruction.

The paper reports a case of coenzyme Q10 deficiency nephrotic syndrome associated with coenzyme Q2 gene mutation and reviews the literature on this topic. The patient presented with hematuria, proteinuria, and a diminution of vision as clinical manifestations. But the proteinuria was not relieved after sufficient doses of glucocorticoids for over 2 months. The patient′s birth history was unremarkable, and his parents were both healthy and not consanguineous. Whole exome sequencing revealed that the patient had a mutation of coenzyme Q2 gene at c.973A>G(p.T325A) and c.517C>T(p.R173C). Combined with renal biopsy pathology, the patient was diagnosed with hereditary nephropathy and started the supplements of coenzyme Q10 after stopping glucocorticoid treatments immediately. After 5 weeks of therapy, the patient′s 24-h urine protein quantification decreased from 6.01 g to 1.53 g.

Objective:To investigate the relationship between number of daily steps and insomnia in patients with chronic insomnia using "WeChat Sports" program.Methods:A total of 190 patients with insomnia who received treatment in Department of Neurology, Zhejiang University of Traditional Chinese Medicine Affiliated Wenzhou Hospital between October 2017 and October 2019. General data (age, sex, body mass index, history of smoking and alcohol use) and the number of daily steps recorded by "WeChat Sports" program were collected. Patients whose average number of daily steps was greater than 7500 were assigned to the sufficient exercise group ( n = 68), and the remaining patients were assigned to the insufficient exercise group ( n = 122). Patient symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI), The Patient Health Questionnaire-9, and generalized Anxiety Disorder scale-7. Scale evaluation and data collection were performed by two trained investigators. Data were compared between the two groups. The correlation between average number of daily steps and each scale score was analyzed. Results:Total PSQI score in the sufficient exercise group was significantly lower than that in the insufficient exercise group [(12.94 ± 3.14) points vs. (14.93 ± 2.99) points, t = 4.31, P < 0.001]. Scores of subjective sleep quality, sleep latency, habitual sleep efficiency, use of sleep medication, and daytime dysfunction were significantly lower in the sufficient exercise group than those in the insufficient exercise group ( P = 0.011, 0.008, 0.025, 0.039, 0.006). The Patient Health Questionnaire-9 and Generalized Anxiety Disorder Scale-7 scores in the sufficient exercise group were significantly lower than those in the insufficient exercise group ( P = 0.011, P = 0.002). The average number of daily steps was significantly negatively correlated with total PSQI score, Patient Health Questionnaire-9 score, Generalized Anxiety Disorder Scale-7 score, and score of each PSQI component (subjective sleep quality, sleep latency, habitual sleep efficiency, and daytime dysfunction) ( r = -0.29, -0.16, -0.19, -0.24, -0.15, -0.18, -0.23). Conclusion:Insomnia patients with insufficient daily exercise have more serious insomnia and emotional symptoms than those with sufficient daily exercise. Daily average exercise is correlated with the severity of insomnia and emotional symptom.
