OBJECTIVE: To investigate the accuracy of color Doppler ultrasound (CDU) and CT angiography (CTA) in the preoperative evaluation of perforator vessels in free posterior interosseous artery perforator (PIAP) flaps. METHODS: Between January 2020 and December 2023, 19 patients with hand skin and soft tissue defects caused by trauma were admitted. There were 11 males and 8 females, with a median age of 45 years (range, 26-54 years). The interval between injury and admission was 5-11 days (mean, 7.2 days). The skin and soft tissue defects were located on the dorsum of the hand in 8 cases and on the fingers in 11 cases. The size of defect ranged from 4.0 cm×2.5 cm to 7.5 cm×3.5 cm. After locating the perforator vessels through CDU and CTA before operation, the free PIAP flaps were designed to repair hand defects, with the size of 4.5 cm×3.0 cm-7.5 cm×4.0 cm. The defects of donor sites were directly sutured. The number and diameter of perforator vessels in the posterior interosseous artery detected by CDU and CTA were compared. The differences in localization of perforator vessels using CDU and CTA and their clinical effects were also compared to calculate the accuracy and recognition rate. During follow-up, the survival of the skin flap was observed, and the Vancouver scar scale (VSS) score was used to evaluate the healing of the donor site, while the visual analogue scale (VAS) score was used to evaluate the patient's satisfaction with the appearance of the skin flap. RESULTS: The number and the diameter of PIAP vessels was 5.8±1.2 and (0.62±0.08) mm assessed by CDU and 5.2±1.0 and (0.60±0.07) mm by CTA, showing no significant difference between the two methods ( P>0.05). The number, course, and distribution of perforator vessels of the PIAP vessels observed during operation were basically consistent with those detected by preoperative CDU and CTA. Compared with intraoperative observation results, the recognition rates of dominant perforating vessels by CDU and CTA were 95.0% (18/19) and 89.5% (17/19), respectively, and the accuracy rates were 100% (19/19) and 84.2% (16/19), with no significant difference between the two methods ( P>0.05). All flaps survived after operation, and all wounds and incisions at donor sites healed by first intention. All patients were followed up 6-13 months (mean, 8.2 months). At last follow-up, the skin flaps had elasticity and soft texture，with the patient satisfaction VAS score of 9.2±0.8. The donor sites had no obvious scar hyperplasia with the VSS score of 11.7±0.9. CONCLUSION CDU and CTA accurately identify the dominant perforator vessels and provide reliable information for vessel localization, facilitating precise flap harvesting and minimizing donor site injury. However, CDU offers superior visualization of distal end of perforator vessels in the forearm compared to CTA.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Objective:To investigate the self-care contribution and binary coping level of spouse caregivers for middle-aged and young stroke patients and explore the relationship between the two, in order to improve the quality of self-care contribution of spouse caregivers to middle-aged and young stroke patients.Methods:A cross-sectional survey was conducted among 200 middle-aged and young stroke patients ′ spouse caregivers in the People ′s Hospital of Xinjiang Uygur Autonomous Region from January to June 2023 by the general data questionnaire, the Caregiver Contribution to Self-care of Stroke Patient Scale, the Dyadic Coping Inventory. The correlation between self-care contributions and binary coping strategies of spousal caregivers was analyzed, and the factors that affect their self-care contributions were screened. Results:Finally, 192 middle-aged and young stroke patients ′ spouse caregivers were included, including 70 males and 122 females, aged 18-59 years old. The total score of self-care contribution of spousal caregivers of middle-aged and young stroke patients was (75.43 ± 6.80) points, and the total score of binary coping was (117.12 ± 9.59) points, both of which were positively correlated ( r=0.691, P<0.05). Hierarchical regression analysis showed that after controlling for the influence of general data, binary coping could explain 28.4% variation in the self-care contribution of spouse caregivers of middle-aged and young stroke patients ( P<0.05). Conclusions:The duality coping level positively predicts the quality of spouse caregivers ′ self-care contribution to middle-aged and young stroke patients. Medical staff should assess the dual coping level of middle-aged and young stroke patients and their spouses, and carry out targeted dual intervention measures to improve the quality of caregivers' contribution to stroke patients ′ self-care.

Objective To investigate the correlation between the level of oxidative stress indicators in placental tissues and placental perfusion level in twin-to-twin transfusion syndrome (TTTS). Methods A total of 105 cases of dichorionic monoamniotic monozygotic twin pregnant women were included in the study. They were divided into control group of 90 cases and observation group of 15 cases based on whether TTTS occurred during pregnancy. The levels of oxidative stress indicators[malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX)]in placental tissues below the attachment points of the two umbilical cords in the two groups were detected. The maximum diameters of arterio-arterial (AA) anastomosis, veno-venous (VV) anastomosis, and arterio-venous (AV) anastomosis, as well as the difference ratio of placental tissue areas (PTD), were compared between the two groups. The correlation between the levels of oxidative stress indicators in placental tissues and placental perfusion level was analyzed. Results Compared with placental A and placental B in the control group, the MDA level in the placental tissues of the blood supply end and the blood recipient end in the observation group was increased, while the SOD and GSH-PX levels were decreased, and the maximum diameter of AA anastomosis was reduced, there were statistically significant differences (P < 0.05). In the observation group, the MDA level in the placental tissues of the blood supply end was higher than that of the blood recipient end, the SOD and GSH-PX levels were lower than those of the blood recipient end, and the maximum diameter of AA anastomosis was smaller than that of the blood recipient end, with statistically significant differences (P < 0.05). The maximum diameters of AV anastomosis and PTD in the observation group were larger than those in the control group (P < 0.05). There was no significant difference in the maximum diameter of VV anastomosis between the two groups (P>0.05). Pearson correlation analysis showed that there were no significant correlations of MDA, SOD and GSH-PX levels with the maximum diameter of AA anastomosis and PTD in the placental tissues of the control group (P>0.05).In the placental tissues of the blood supply end and the blood recipient end in the observation group, MDA levels showed a strong negative correlation with the maximum diameter of AA anastomosis and a strong positive correlation with the maximum diameter of AV anastomosis and PTD (P < 0.05). SOD and GSH-PX levels showed strong positive correlations with the maximum diameter of AA anastomosis and strong negative correlations with the maximum diamete of AV anastomosis and PTD (P < 0.05). Conclusion There is a significant imbalance of oxidative stress in placental tissues of TTTS pregnant women, and the decrease in antioxidant activity of placental tissues may be an important cause of placental perfusion injury.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Objective: To investigate the antimicrobial resistance in and multilocus sequence typing (MLST) of Campylobacter jejuni in meat and meat products in Liaoning Province, so as to provide insights into the management of C. jejuni infection. Methods: Nine C. jejuni isolates from meat and meat products in 2020 were subjected to whole genome sequencing, and the minimum inhibitory concentration was measured with the agar dilution method. MLST of C. jejuni isolates was performed with the microbial resistance mechanism traceability reference database and analysis system. Results: Six drug-resistant C. jejuni isolates were detected, and there were four multidrug-resistant isolates. There were six C. jejuni isolates resistant to tetracycline, five isolates resistant to nalidixic acid, four isolates resistant to ciprofloxacin, two isolates resistant to florfenicol, one isolate resistant to gentamicin and one isolate resistant to streptomycin. Nine C. jejuni isolates showed sensitive to azithromycin, chloramphenicol and clindamycin. MLST identified six ST types in nine C. jejuni isolates, with ST45 and ST2274 as the predominant type, and detected one isolate with unclassified ST type. Phylogenetic analysis showed that KW028 and KW029 of ST45 type were closely related and had high homology, and KW040 and KW042 of ST2274 type were closely related with high homology, while KW007 of ST6701 type was closely related to KW040 and KW042 of ST2274 type, with only one pgm housekeeper gene in difference. Conclusions High resistance to tetracycline, nalidixic acid and ciprofloxacin was detected in nine C. jejuni isolates from meat and meat products, and ST45 and ST2274 were predominant ST types of C. jejuni.

Primary prostate synovial sarcoma (PPSS) is rare in clinic. One patient was admitted to our hospital in May 2021. The patient was admitted to the hospital because of the physical examination. Preoperative pelvic enhanced MR, PETCT and preoperative puncture pathology suggested that pelvic soft tissue sarcoma was likely. Robot-assisted radical resection of pelvic tumor was performed, and the unilateral PPSS was diagnosed by postoperative pathology, immunohistochemistry and gene detection. Patients were treated with ifosfamide + adriamycin adjuvant chemotherapy one month after operation, and Proton therapy radiotherapy five months after operation. Follow-up for more than 2 years showed that the patients were generally in good condition, and no recurrence or metastasis was found in imaging.
