Objective To explore the function of electroacupuncture(EA)on body mass,fasting blood glucose,heat pain threshold,and transient receptor potential vanilloid 4(TRPV4)in the dorsal root ganglia(DRG)of rats with diabetic neuropathic pain(DNP).Methods A DNP rat model was formed by intraperitoneally injecting the animals with STZ.From days 15 to 21,bilateral Zusanli and Kunlun points of the DNP rat model were treated with electroacupuncture once daily for 30 min.We then measured their body mass,fasting blood glucose,and heat pain threshold.The co-expression of TRPV4 and NeuN in the rat L4～L6 DRG was detected by immunofluorescence.The effects of the TRPV4 agonist GSK1016790A on body mass,fasting blood glucose,and the heat pain threshold of DNP rats treated with electroacupuncture were detected.Results After the 7th day,body mass was significantly decreased(P<0.01)and fasting glucose was significantly increased(P<0.01)in the model group compared with the normal group.After the 21st day,compared with the model group,heat pain threshold of the model+electroacupuncture group was significantly higher(P<0.01);the results of co-expression of TRPV4 and NeuN immunofluorescence on rat L4～L6 DRG showed that:the expression of positive cells in the model group was significantly higher(P<0.01)than that in the normal group,the co-expression of TRPV4 and NeuN positive cells in L4～L6 DRG of rats in the model+electroacupuncture group was significantly lower(P<0.01)than that in the model group.The TRPV4 agonist GSK1016790A can reverse the downregulation of thermal pain threshold induced by electroacupuncture in DNP rats(P<0.01).Conclusion Electroacupuncture alleviated the DNP induced by STZ,and its mechanism may involve the inhibition of TRPV4 protein expression in the DRG.

Objective:To systematically synthesize the real experiences of cancer patients undergoing prehabilitation and provide a reference for the development of targeted prehabilitation programs.Methods:A systematic search was conducted in China National Knowledge Infrastructure, Wanfang Data, VIP, China Biology Medicine disc, Web of Science, PubMed, Embase, CINAHL, and Cochrane Library databases for qualitative studies on the prehabilitation experiences of cancer patients. The quality of the included studies was appraised, and the findings were integrated using a Meta-aggregative approach. The search covered publications up to June 30, 2024.Results:A total of 17 studies were included, yielding 76 themes. These were synthesized into 12 categories and further integrated into four integration results: heavy physical and psychological burden with low adherence to programs; positive cognition supported by multiple factors leads to high adherence under appropriate interventions; unmet practical needs require urgent attention; physical and psychological benefits are sustained and influential.Conclusions:Multiple factors affect patients' adherence to prehabilitation, and unmet needs are common. Future research should aim to identify barriers and meet patients' needs.

Objective:Explore the feasibility and advantages of using proximal and distal ends of thoracodosal artery and vein as recipient vessels in deep inferior epigastric perforator flap immediate breast reconstruction.Methods:The clinical data of patients who underwent breast reconstruction surgery using the proximal and distal ends of the thoracodorsal vein as recipient vessels at the Department of Breast and Thyroid Surgery of the Second Affiliated Hospital of Hainan Medical University from March 2022 to June 2023 were analyzed retrospectively. Preoperative examinations included thoracoabdominal angiography and color Doppler ultrasonic localization of the main trunk and perforators of the inferior epigastric vessels. The procedure began with mastectomy and axillary lymph node dissection, followed by the isolation of bilateral perforators and the main trunk of the abdominal flap. The main trunks of the bilateral inferior epigastric arteries were then transected, and their vascular pedicles exposed and anastomosed respectively to the proximal and distal ends of the thoracodorsal artery and vein. Both arteries and veins were joined end-to-end. The flap after trimming and reconstruction was then implanted into the cavity left after mastectomy through the incision. Breast positioning was performed with the patient in a knee-bent and hip-flexed position. After adjusting the shape of the reconstructed breast. The donor site was closed, the umbilicus was reconstructed, drainage tubes were placed, and the breast incision was closed. Postoperative follow-up monitored complications associated with the flap and patient satisfaction with the breast reconstruction, utilizing a self-assessment method.Results:Four female patients were included, aged (46.0±6.5) years, ranging from 37 to 52 years. All four patients had bilateral vascular pedicles in the donor area, with three patients having thoracodorsal vessels at the distal and proximal ends as recipient vessels, and one patient having anterior serratus branch of the thoracodorsal vessels at the distal and proximal ends. All drainage tubes were removed within 7 to 10 days after surgery. Patients were discharged. Follow-up period ranged from 1 to 15 months, averaging 6 months. The patients recovered well postoperatively, with no flap-related complications occurring. All four patients were satisfied with the result of the reconstruction.Conclusion:The simultaneous application of the proximal and distal ends of the thoracodorsal artery and vein can ensure the safety of flap survival while reducing damage to the ribs and intercostal muscles, achieving better aesthetic result.

Objective:To investigate the prognosis and influencing factors in critically ill surgical patients of different feeding intolerance trajectories.Methods:The retrospective cohort study was conducted. The clinical data of 354 critically ill surgical patients who were admitted to 69 medical centers in the Chinese Critical Care Nutrition Trials Group -NEED database from March 2018 to July 2019 were selected. There were 247 males and 107 females, aged 58(46,68)years. According to the trajectory model of feeding intolerance change, 354 patients were divided into 3 categories as feeding intolerance, decreased feeding intolerance, continuous feeding intolerance, including 164, 49, 141 cases respectively. Observation indicators: (1) general situations of patients of different feeding intolerance trajectories; (2) treatment of patients of different feeding intolerance trajectories; (3) survival of patients of different feeding intolerance trajectories; (4) analysis of pro-gnostic factors in critically ill surgical patients. Measurement data of normal distribution were expressed as Mean± SD, and one-way analysis of variance was used for comparison between groups. Measurement data of skewed distribution were expressed as M( Q1, Q3), and Kruskal-Wallis rank sum test was used for comparison between groups. Count data were expressed as absolute numbers or percentages, and chi-square test was used for comparison between groups. Ordinal data were compared using the Kruskal-Wallis rank sum test. Bonferroni correction was used for pairwise comparison. Group-based trajectory model was constructed according to Traj plug-in in Stata17.0 statistical software, and the optimal trajectory model was evaluated by Bayesian information criterion and average posterior probability parameter. The Kaplan-Meier method was used to draw the survival curve and calculate the survival rate, and Log-Rank test was used for survival analyses. Univariate and multivariate analyses were conducted using the COX proportional hazard regression model. Results:(1) General situations of patients of different feeding intolerance trajectories. Of 354 critically ill surgical patients, 257 cases underwent enteral nutrition and 97 cases underwent enteral plus parenteral nutrition. The acute physiological and chronic health score (APACHEII) was 17(13,21), and the sequential organ failure score (SOFA) was 6(5,8). The modified Critical Illness Nutritional risk score (mNUTRIC) was 4 (2,5), the number of complications was 2(1,3). There were 293, 55 and 6 patients with grade Ⅰ, grade Ⅱ and grade Ⅲ acute gastrointestinal injury (AGI), and there were 224, 17 and 61 patients who were treated with mechanical ventilation, continuous renal replacement therapy and vasoactive drugs, respectively. The incidence of feeding intolerance in 354 patients increased first and then decreased, reaching a peak of 25.42%(90/354) on the third day and 53.67%(190/354) within 7 days. Of 354 critically ill surgical patients, cases with no feeding intolerance, decreased feeding intolerance, continuous feeding intolerance had the APACHE Ⅱ as 16(12,20), 17(14,25), 18(13,22), mNUTRIC as 3(2,5), 4(3,6), 4(3,5), the number of complications as 2(1,2), 2(2,3), 2(2,3). There were 152, 27, 114 cases with grade Ⅰ AGI, 12, 22, 27 cases with grade Ⅱ-Ⅲ AGI, 95, 39, 90 cases with mechanical ventilation. There were significant differences in the above indicators among the three groups ( H=6.14, 13.11, 28.05, χ2=37.96, 7.65, P< 0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance and continuous feeding intolerance had the higher number of complications and grade of AGI ( Z=60.32, 54.69, χ2=39.72, 9.52, P<0.05), patients with decreased feeding intolerance had the higher mNUTRIC scores and ratio of mechanical ventilation ( Z=53.41, χ2=7.59, P<0.05). (2) Treatment of patients of different feeding intolerance trajectories. Cases with prokinetic drugs use and post-pyloric feeding were 36, 13 of patients with no feeding intolerance, 25 and 10 of patients with decreased feeding intolerance, 46 and 19 of patients with continuous feeding intolerance, respectively, showing significant differences in the above indicators among the three groups ( χ2=15.76, 6.20, P<0.05). Further analysis showed that compared with patients with no feeding intolerance, patients with decreased feeding intolerance had higher ratio of prokinetic drugs use and ratio of post-pyloric feeding ( χ2=15.60, 6.10, P<0.05). (3) Survival of patients of different feeding intolerance trajectories. The 28-day overall survival rates of patients with no feeding intolerance, decreased feeding intolerance, and continued feeding intolerance were 96.96%, 95.92%, and 87.94%, respectively, showing a significant difference ( χ2=10.39, P<0.05). Further analysis showed a significant difference between patents with no feeding intolerance and patients with continuous feeding intolerance ( χ2=9.19, P<0.05). (4) Analysis of prognostic factors in critically ill surgical patients. Multivariate analysis showed that continuous feeding intolerance was an independent risk factor for 28-day death in critically ill surgical patients ( hazard ratio=3.92, 95% confidence interval as 1.43-10.79, P<0.05). Conclusion:For surgical critically ill patients, patients with continuous feeding intolerance have a higher 28-day mortality than patients with no feeding intolerance, and the continuous feeding intolerance is an independent risk factor for 28-day death in critically ill surgical patients.
