Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

Background and Aims:Totally implantable venous access port(TIVAP)are widely used for chemotherapy,blood transfusion,and nutritional support in patients with malignancies.Among them,upper arm port(UAP)are increasingly recommended in clinical practice due to their advantages in avoiding thoracic complications and providing more concealed incisions.Currently,two main implantation techniques are used for UAP:the tunnel needle-transverse incision technique and the puncture point-transverse incision technique.This study aims to compare the clinical outcomes of these two techniques in patients with hematological malignancies,focusing on safety and cosmetic appearance,to provide evidence for clinical decision-making.Methods:A retrospective analysis was conducted on 412 patients with hematological malignancies who underwent UAP implantation at Xiangya Hospital of Central South University between December 2021 and December 2024.Based on the implantation method,patients were divided into the tunnel needle-transverse incision group(n=200)and the puncture point-transverse incision group(n=212).Intraoperative variables(operative time,intraoperative pain score,catheter kinking at the pocket,intraoperative blood loss)and postoperative indicators(incidence of complications and incision aesthetic satisfaction)were compared between the two groups.Results:There were no significant differences in baseline characteristics between the two groups(all P>0.05),indicating comparability.The puncture point-transverse incision group showed superior performance in operative time[(32.99±4.91)min vs.(41.42±5.35)min],catheter kinking rate(1.4％vs.8.5％),and incision aesthetic satisfaction(7.99±0.58 vs.6.26±0.86)compared with the tunnel needle-transverse incision group(all P<0.05).Although the puncture point group had slightly more intraoperative bleeding[(4.52±1.02)mL vs.(4.16±0.83)mL],the difference,while statistically significant,was of limited clinical relevance.No significant differences were observed between the two groups in intraoperative pain scores or incidence of postoperative complications(both P>0.05).Conclusion:The puncture point-transverse incision technique offers significant advantages in terms of operative efficiency,reduced catheter kinking,and improved incision aesthetics,without compromising safety.It represents a promising alternative to the traditional tunnel needle-transverse incision method and has strong potential for broader clinical adoption.The puncture point-transverse incision technique offers advantages such as shorter operative time,lower catheter kinking rate,and higher incision aesthetic satisfaction.It is a promising alternative to the traditional tunnel needle-transverse incision technique and has good potential for clinical application and promotion.

The polyfoliate perforator flap is a new type of flap that was developed on the basis of the traditional polyfoliate myocutaneous flap, polyfoliate fascial flap and perforator flap. It overturns the traditional idea that the deep fascial vascular network is the fundamental for a survival of the flap, and enables the flaps to achieve the best profile and function of the recipient areas with minimal damage to the donor area. In order to improve the understanding of the polyfoliate perforator flap and further standardise its clinical application, this paper forms a consensus on the definition, classification, indications, operative points and precautions of the polyfoliate perforator flap, so as to provide references in diagnosis and treatment process and practical application for the surgeons.

Preeclampsia is the main cause of poor maternal-fetal outcomes. A series of cell and animal experiments, and a small number of clinical studies have shown that pravastatin can prevent and treat preeclampsia by regulating angiogenesis, increasing the expression of heme oxygenase, and stimulating the production of nitric oxide without any reported adverse effects during pregnancy. We review the latest progress on the mechanism, effect, and safety of pravastatin in the prevention and treatment of preeclampsia.

Objective:To explore the effect of the operation process query system and the psychological impact on the surgical patient's family members.Methods:From April to October 2019, 198 family members of patients whose operation time> 1 hour were selected from the Shanghai East Hospital, Tongji University. The patients were divided into a control group and an observation group according to the order of operation, with 99 cases in each group. Both groups implemented preoperative visits, preoperative assessments, and preoperative education. The control group performed routine nursing of Operating Room and did not specifically inform family members of the information about the operation process during the operation. The family members of the observation group could view information about the operation process in the operation progress query system. The State-Trait Anxiety Inventory (S-AI) was used to assess the anxiety of the family members of the two groups of patients, and we compared the changes of pulse, respiration and blood pressure before and during the operation of the two groups of family members, and compared the satisfaction of the family members of the two groups after the operation.Results:The anxiety scores and vital signs of the family members of the two groups of patients during the operation were higher than those before the operation. The family members of the observation group had an intraoperative anxiety score of (49.01±7.91) , pulse (92.97±8.76) times/min, respiration (20.13±1.64) times/min, systolic blood pressure (122.06±11.69) mmHg, diastolic blood pressure (82.86±6.45) mmHg, all lower than those of the control group, the differences were statistically significant ( t=20.494, 6.749, 26.784, 4.387, 8.139; P<0.01) . The total satisfaction of the family members of the observation group after the operation was 95.96% (95/99) , and that of the control group was 63.64% (63/99) , and the difference was statistically significant (χ 2=34.932, P<0.01) . Conclusions:The application of the operation query system can effectively alleviate the psychological anxiety of the family members of the surgical patients and improve the satisfaction of the family members of the patients with the operation.

Objective:To investigate the effects of microskin transplantation with antigen-free porcine peritoneum (AFPP) as substitutive carrier for allogeneic skin graft in treating patients with extensive deep burns.Methods:Medical records of 32 patients with extensive deep burns, hospitalized in Changhai Hospital of Naval Medical University meeting the inclusion criteria were investigated from January 2014 to December 2017. Twenty patients [12 males and 8 females, aged (35.4±2.2) years]with microskin transplantation using allogeneic skin graft as microskin carrier were included in allogeneic skin graft group and 12 patients [6 males and 6 females, aged (32.1±4.8) years] with microskin transplantation using AFPP as microskin carrier were included in AFPP group. On post injury day 3-7, the vital signs of patients were stable and escharectomy and autologous microskin grafting of head were performed. The expansion ratio of microskin, the application time of albumin and antibiotics, the percentage of infectious autologous microskin grafting area, the survival rate of microskin, and dressing change times of patients in 2 groups were recorded. Data were statistically analyzed with t test. Results:The expansion ratio of microskin of patient in AFPP group was 14.8±0.6, which was close to 13.5±0.6 of allogeneic skin graft group ( t=1.531, P>0.05). The application time of albumin and antibiotics of patients in AFPP group were close to those of allogeneic skin graft group ( t=0.027, 1.121, P>0.05). The percentage of infectious autologous microskin grafting area of patients in AFPP group was (8.5±1.2)%, which was significantly lower than (18.1±0.6)% in allogeneic skin graft group in 4 weeks after surgery( t=7.593, P<0.01), the survival rate of microskin of patients in AFPP group was (82.5±1.1)%, which was significantly higher than (72.5±0.6)% in allogeneic skin graft group ( t=8.689, P<0.01). The dressing change time of patients in AFPP group was significantly less than that in allogeneic skin graft group ( t=4.743, P<0.01). Conclusions:Compared with allogeneic skin graft, microskin transplantation with AFPP as carrier can reduce wound infection, improve the survival rate of microskin graft, and reduce dressing change time, so that AFPP is a good carrier of microskin.
