Objective To investigate the safety and feasibility of the domestic SA-1000 single-port single-arm robot-assisted laparoscopic system in total hysterectomy.Methods Data from 16 patients who underwent total hysterectomy using the SA-1000 system at the Department of Obstetrics and Gynecology,The Second Affiliated Hospital of Naval Medical University,between Mar.2023 and Jan.2024 were retrospectively collected.Surgical parameters were analyzed.Postoperative pain was assessed using the visual analogue scale(VAS)at 24 h after surgery and before discharge.Incision cosmesis was evaluated 3-5 weeks postoperatively using the body image questionnaire(BIQ,score range 3-24).Results All 16 procedures were successfully completed using the SA-1000 system without conversion to open surgery,achieving a 100.0%procedural success rate.The mean whole surgery time was(234.40±56.24)min.The median robotic arm setup time was 8.0(4.0,13.5)min,and the median console operating time was 128.0(100.0,151.0)min.The median intraoperative blood loss was 100.0(100.0,200.0)mL.No perioperative complications,such as hemorrhage,infection,injury to adjacent organs(ureters,bladder,bowel),poor wound healing,or incisional hernia,were observed.The mean wound pain score at 24 h postoperatively was 3.81±1.64,decreasing to a median of 3.0(2.0,4.0)before discharge.The BIQ score assessed at 3-5 weeks postoperatively was 21.88±1.15.Conclusion The application of the domestic SA-1000 single-port single-arm robot-assisted laparoscopic system for total hysterectomy is safe and feasible,demonstrating favorable surgical outcomes.It holds promise for broader implementation and promotion in domestic medical centers.

Objective:To investigate the improvement effect of the freeze-dried garlic powder on acute myocardial ischemia and its effect on phosphatidylinositol 3 kinase/protein kinase B/nuclear factor erythroid 2-related factor 2 (PI3K/Akt/Nrf2) signaling pathway.Methods:SD rats were randomly divided into sham-operation group, model group, positive drug group, and garlic freeze-dried powder low-, medium-, and high-dosage groups using a random number table method, with 12 rats in each group. The garlic freeze-dried powder low-, medium-, and high-dosage groups were orally administered with 0.58, 1.16, and 2.32 g/kg of garlic freeze-dried powder solution, the positive reference drug group was orally administered with 0.26 g/kg of compound Danshen tablet solution, and the model group and sham-operation group were orally administered with equal volumes of distilled water once a day for 14 consecutive days. Except for the sham-operation group, all other groups were prepared with acute myocardial ischemia models in rats by ligating the left anterior descending coronary artery. Electrocardiogram testing was performed. The incidence of ventricular premature beats, ventricular tachycardia, and ventricular fibrillation in each group was counted. Myocardial infarction was observed through TTC staining, and the myocardial infarction rate was calculated; serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), LDH, cardiac troponin T (cTnT), total antioxidant capacity (T-AOC), SOD, MDA, IL-1β, TNF-α levels were detected, and Western blot was used to detect myocardial tissue p-PI3K, p-Akt, Nrf2, HO-1 and Keap1 proteins.Results:Compared with the model group, the incidence of premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation in rats in each treatment group was reduced. Compared with the model group, the positive drug group and garlic freeze-dried powder medium- and high-dosage groups showed a decrease in myocardial infarction rate in rats ( P<0.05); compared with the model group, the levels of serum T-AOC and SOD in each treatment group increased ( P<0.05 or P<0.01), while the level of MDA decreased ( P<0.05 or P<0.01); the levels of CK, LDH, cTnT, IL-1β, and TNF-α in the serum of rats in the positive drug group and garlic freeze-dried powder high-dosage group decreased ( P<0.05 or P<0.01), while the expressions of p-PI3K, p-Akt, Nrf2, and HO-1 proteins in myocardial tissue increased ( P<0.05 or P<0.01), and the expression of Keap1 protein decreased ( P<0.05 or P<0.01). Conclusions:Garlic freeze-dried powder can improve acute myocardial ischemia of rats by reducing the release of serum myocardial enzymes and exerting antioxidant and anti-inflammatory effects. The mechanism may be related to regulating PI3K/Akt/Nrf2 signaling pathway.

Objective To analyze the application effect of multidisciplinary collaborative nursing based on the Information-Knowledge-Attitude-Practice(IKAP)theory in patients undergoing lobectomy via thoracoscopy.Methods A total of 168 patients undergoing lobectomy via thoracoscopy were se-lected,and randomly divided into control group and observation group using a random number table,with 84 patients in each group.The control group received routine nursing,while the observation group received multidisciplinary collaborative nursing based on the IKAP theory in addition to routine nurs-ing.The postoperative recovery,pulmonary function indicators[forced vital capacity(FVC),maxi-mum voluntary ventilation(MVV)and ratio of forced expiratory volume in the first second to forced vi-tal capacity(FEV1/FVC)],self-efficacy[General Self-Efficacy Scale(GSES)score]and self-man-agement ability[Chronic Disease Self-Management Questionnaire(CDSMQ)score]before and after intervention were observed and compared between the two groups.Results The observation group had shorter first ambulation time,first flatus time and length of hospital stay compared with the control group(P＜0.05).Before intervention,there were no statistically significant differences in FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores between the two groups(P＞0.05).After inter-vention,the observation group had higher FVC,MVV,FEV1/FVC,CDSMQ scores and GSES scores compared with the control group(P＜0.05).Conclusion Multidisciplinary collaborative nursing based on the IKAP theory can effectively promote the recovery process in patients undergoing lobec-tomy via thoracoscopy,improve postoperative pulmonary function,self-management ability,and self-efficacy,thereby enhancing the quality of rehabilitation.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Objective By comparing with arthroscopic rotator cuff repair alone,to explore the efficacy and difference of leukocyte poor platelet-rich plasma(LP-PRP)and leukocyte rich platelet-rich plasma(LR-PRP)in arthroscopic rotator cuff repair.Methods Sixty patients with total rotator cuff tear accompanied by arthroscopic rotator cuff repair admitted to the Affiliated Hospital of North China University of Science and Technology from October 2021 to September 2022 were included and randomly divided into control group(n=20),LP-PRP group(n=20)and LR-PRP group(n=20).The control group only received arthroscopic rotator cuff repair.The LP-PRP group was injected with leukocyte poor platelet-rich plasma(LP-PRP)into the sutured torn tendon after the same operation,and the LR-PRP group was injected with leukocyte rich platelet-rich plasma(LR-PRP)into the sutured torn tendon after the same operation.The postoperative rehabilitation training plan of the three groups was the same,and the postoperative follow-up and evaluation were conducted for 1 year.It included pain score(VAS score),shoulder joint function score(CMS,UCLA,ASES score),retear rate and related complications.Results All patients were followed up.(1)VAS score:Compared with the LR-PRP group and the control group,the results were statistically significant only at 1,3 and 6 weeks after surgery(P<0.05);There was no statistical significance between the LR-PRP group and the control group at 1 week,3 weeks,6 weeks,3 months,6 months and 12 months after surgery(P>0.05).(2)CMS,UCLA and ASES scores:There were no significant differences between the LP-PRP group and the LR-PRP group at 3 months,6 months and 12 months after surgery(P>0.05);Compared with LP-PRP group and LR-PRP group,there were significant differences in each follow-up time point of control group(P<0.05).(3)Retear rate:In the LP-PRP group,there was 1 retear in the LR-PRP group(tear rate 5%),and 3 in the control group(tear rate 15%).There was no statistically significant difference between the three groups(P>0.05).(4)There were no postoperative complications in 60 patients.Conclusions Compared with arthroscopic rotator cuff repair alone,although the application of LP-PRP and LR-PRP could not reduce the rate of retear,it could significantly improve the shoulder joint function of patients,and LP-PRP could significantly reduce the pain of patients with rotator cuff injury in the early postoperative period(within 6 weeks),with no postoperative complications,and the short-term clinical results of patients were satisfactory.

Objective To observe the effect of family-involved nursing model under the concept of rapid recovery in perioperative nursing for patients with pulmonary nodules. Methods A total of 180 patients with surgical treatment for pulmonary nodules were selected and randomly divided into control group and observation group, with 90 cases in each group. The control group was conducted with routine nursing, while the observation group was conducted with family-involved nursing model under the concept of rapid recovery. The time-related outcomes, preoperative anxiety, family burden, and postoperative training enthusiasm were compared between the two groups. Results The duration of chest tube indwelling and total hospital stay in the observation group were significantly shorter than those in the control group (P<0.05). After the intervention, the scores of the Amsterdam Preoperative Anxiety and Information Scale (APAIS) and the Family Burden Scale (FBS) in the observation group were significantly lower than those in the control group (P<0.05). The level of postoperative training enthusiasm in the observation group was significantly higher than that in the control group (P<0.05). Conclusion The implementation of family-involved nursing model under the concept of rapid recovery can promote early recovery of patients with pulmonary nodules after surgery, alleviate preoperative anxiety, reduce family burden, and improve the enthusiasm of patients for postoperative rehabilitation training.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the relationship between spicy diet and uremic pruritus(UP)in the patients with maintenance haemodialysis(MHD).Methods A total of 403 patients receiving the treat-ment in the blood purification center of this hospital from December 2023 to February 2024 were selected as the study subjects and grouped by the sum of the scores of frequency and degree of pepper intake.The visual analogue rating scale(VAS)was used to conduct the preliminary pruritus score in all patients,and the pa-tients with the score＞0 point conducted the multidimensional evaluation by the 14-item uremic skin pruritus scale.The blood routine and itch-related blood biochemical indexes levels of all patients were measured.Results There were 65 cases in the bland diet group,119 cases in the mild spicy diet group and 219 cases in the spicy diet group,and there was no significant difference in the number of genders between the groups(P＞0.05).There were statistically significant differences in age,dialysis age and lymphocyte count among the groups(P＜0.05).There was no statistically significant difference in the degree of pruritus among the groups(Z=9.301,P=0.157),but it was seen that the proportion of moderate and severe pruritus in the mild spicy diet group and the spicy diet group was decreased,and the proportions of no pruritus and mild pruritus showed the increasing trend.The itching score of the bland diet group was higher than that of the mildly spicy diet group and spicy diet group,and the difference was statistically significant(P＜0.05),but there was no statistically significant difference between the mild spicy diet group and spicy diet group(P＞0.05).There was a statistically significant difference in the itch score of the patients aged 40-60 years in each group(P＜0.05),and there was no statistically significant difference in the itch score between the patients aged＞60 years old and＜40 years old in each group(P＞0.05).There was no statistically significant difference in the itch-related blood biochemical indexes among the groups(P＞0.05).Conclusion The spicy diet may reduce the degree of pruritus in patients with MHD,moreover which is not affected by the age and other factors,and may be associated with lymphocyte level decrease in the patients.
