Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m². Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

Lung cancer （LC） is a significant global public health issue， with both its incidence and mortality rates ranking among the highest worldwide. The age-standardized incidence and mortality rates are increasing annually， posing a serious threat to the life and health of LC patients. Radical surgical resection is the primary treatment for malignant lung tumors. However， postoperative multidimensional functional impairments， including respiratory， mucosal， and psychological functions， are common. These impairments not only reduce patients' quality of life and affect their treatment tolerance and duration， but also negatively correlate with prognosis， facilitating disease recurrence and metastasis. At present， postoperative functional dysfunction after LC surgery remains a key clinical challenge that urgently needs to be addressed. There is a lack of standardized and regulated postoperative rehabilitation treatment management and traditional Chinese medicine （TCM） differentiation and treatment strategies for LC. Focusing on the core underlying pathogenesis of "Qi sinking" after LC surgery， and guided by the classical TCM theory of "lungs governing Qi"， this study， based on the core concept of the "five perspectives on treatment" theory， innovatively proposes the respiratory dysfunction as the core pathogenesis of "Qi sinking in the chest" during the rapid rehabilitation phase， mucosal dysfunction as the core pathogenesis of "Yin deficiency and Qi sinking" during the postoperative adjuvant treatment phase， and the psychological dysfunction as the core pathogenesis of "Qi sinking with emotional constraint" during the consolidation phase. Accordingly， stage-specific dynamic functional protection strategies are constructed. In the rapid rehabilitation phase， the strategy emphasizes tonifying Qi and uplifting sinking Qi， with differentiation and treatment based on the principle of ''descending before ascending''. In the adjuvant treatment phase， the approach focuses on nourishing Yin and uplifting Qi， with prescription combinations that integrate unblocking and tonification. In the consolidation phase， the strategy aims to resolve constraint and uplift Qi， with clinical treatment emphasizing a combination of dynamic and static methods. At each stage of functional rehabilitation， clinical differentiation and treatment should support healthy Qi and eliminate pathogenic factors simultaneously. This study is the first to propose the concept of postoperative functional protection in TCM， offering a new approach for TCM differentiation and treatment in the full-cycle， stage-based， and dynamic protection of postoperative function in LC patients. It is expected to contribute to the construction and development of an integrated TCM-Western medicine comprehensive program for cancer prevention and treatment in China.

The concept of holism is the core idea of traditional Chinese medicine （TCM）. Various organs and tissues coordinate with each other to maintain the body's life activities， with a close and mutual influence between the spleen， stomach， and the central nervous system （brain）. The gut-brain axis plays an important bridging role between the digestive system and the central nervous system， achieving bidirectional information exchange between the brain and the gastrointestinal tract through complex neuroendocrine and immune mechanisms. The theory of cross-organ interaction involves the mutual influence， coordination， and integration between different organs and systems； multimodality， on the other hand， utilizes multiple sensory modalities， such as vision， hearing， and touch， to convey information. By combining TCM theory with the gut-brain axis theory， a cross-organ multimodal characterization system is established to explore its mechanism and application value in refractory diseases such as functional gastrointestinal disorders， precancerous gastrointestinal diseases， Alzheimer's disease， Parkinson's syndrome， type 2 diabetes， and depression.

Objective:To investigate the efficacy of virtual simulation-guided unilateral locking plate combined with Jail screw technique for double column tibial plateau fractures involving the posterolateral plateau.Methods:A retrospective case series study was conducted to analyze the clinical data of 32 patients with double column tibial plateau fractures involving the posterolateral plateau admitted to Nanjing Drum Tower Hospital Group Suqian Hospital from March 2018 to March 2022, including 20 males and 12 females, aged 37-69 years [(47.5±6.9)years]. According to AO/OTA classification, the fractures were classified as type 41B in 17 patients and type 41C in 15. According to the three-column classification, the fractures were classified as lateral column+posterior column in 17 patients and medial column+posterior column in 15. Virtual simulation technique was used to simulate surgical operation before surgery. After reduction, the patients′ tibial plateau mirror models of the healthy side were used to simulate the implantation of internal fixators on the affected side. The position data of the placed internal fixators were obtained to guide the personalized treatment with unilateral locking plate combined with Jail screw technique. The total number of Jail screws, average number of Jail screws, distribution and accuracy of screw placement, operative duration, intraoperative blood loss, and fracture healing status were recorded. The posterior tibial plateau angle (PTSA), proximal medial tibial angle (MPTA) and Rasmussen anatomical score were compared before operation, at 1, 3, 6, 12 months after operation and at the last follow-up. The Lysholm scores at 6, 12 months after operation and at the last follow-up were used to evaluate the knee function. At the last follow-up, the knee range of motion was measured. Postoperative complications were observed.Results:All the patients were followed up for 28-36 months [(30.7±2.3)months]. The total number of Jail screws inserted was 48, with an average of (1.5±0.5) screws. In the sagittal direction, 1-2 Jail screws were inserted in each patient, with an accuracy rate of 88% (42/48). The operative duration was 78-116 minutes [(98.7±10.5)minutes]. The intraoperative blood loss was 70-120 ml [(96.6±15.6)ml]. All the fractures had healing of stage I, with a healing time of 4-7 months [(5.4±0.9)months]. At 1, 3, 6, 12 months after operation and at last follow-up, the PTSA, MPTA, and Rasmussen anatomical scores were significantly improved when compared with those before operation ( P<0.05), while there was no statistically significant difference between those at various postoperative time points ( P>0.05). The Lysholm knee scores were (83.6±3.9)points, (88.5±3.6)points, and (93.7±2.6)points at 6, 12 months after operation, and at the last follow-up, respectively, which were gradually increased with the passage of the follow-up time ( P<0.05). The range of motion was (121.4±4.6)° in flexion and was 0.0(0.0, 3.0)° in extension at the last follow-up. Two patients had superficial wound infection and 1 had wound dehiscence after operation, which recovered with dressing change or debridement and suturing. No deep infection, vascular injury or nerve damage occurred. Conclusions:The virtual simulation-guided unilateral locking plate combined with Jail screw technique has the advantages of high accuracy of screw placement, shorter operative duration, less intraoperative blood loss, satisfactory fracture reduction, favorable recovery of knee function and range of motion, and fewer postoperative complications in the treatment of double column tibial plateau fractures involving the posterolateral plateau.

Objective:To analyze the association between continuity of consultation and the management of glycosylated hemoglobin (HbA1c) in diabetes patients contracted by family doctors.Methods:This study was a cross-sectional study. From May 2022 to October 2022, three community health service centers in the urban area of Beijing were selected by convenient sampling. A total of 360 diabetes patients were selected by simple random sampling from the selected centers. Extraction of data from electronic health records were conducted to collect patient characteristics, information on the continuity evaluation indicators for patient visits (usual provider of care, UPC) in 2021 and information of monitoring and control indicators for HbA1c in 2021. The monitoring and control of HbA1c in patients with different continuity of consultations were compared. Chi-square test and logistic regression analysis were used to determine the association between continuity of consultation and HbA1c management (i.e., HbA1c monitoring and control).Results:Of the 360 patients, 167 (46.4%) were male; the age was 68.0 (60.0, 74.0) years and the number of years since diagnosis was 11.0 (7.0, 17.0) years. One hundred and fifty-nine patients (44.1%) had UPC scores below 30%, 101 patients (28.1%) had UPC scores between 30% and 50%, and 100 patients (27.8%) had UPC scores above 50%. The compliance rate for HbA1c monitoring was 66.4% (239/360), and the compliance rate for HbA1c control was 45.8% (165/360). When the UPC score was less than 30%, between 30%-50%, and greater than 50%, the HbA1c monitoring compliance rates were 53.5% (85/159), 73.3% (74/101), and 80.0% (80/100), respectively, and the HbA1c control compliance rates were 37.7% (60/159), 51.5% (52/101), and 53.0% (53/100), respectively, and the differences were statistically significant ( χ2=22.36, 7.57, P<0.05). As the UPC score increased, the likelihood of achieving HbA1c monitoring ( OR=1.020, 95% CI:1.009-1.030 , P<0.001) and control ( OR=1.012, 95% CI:1.003-1.021 ,P=0.008) targets increased. Conclusion:There is an association between the continuity of consultation and the management of HbA1c.

Objective:To evaluate the reliability and validity of the Chinese version of Consultation and Relational Empathy (CARE) Measure in the Mandarin speaking population.Methods:From March to June 2018, patient interviews and expert consultations were conducted to explore problems of CARE in Mandarin context and preliminary revisions were made to the measure, then the final adapted tool was developed. A questionnaire survey on the validity of the measure was conducted from July to August 2018, among 373 patients from three community health service centers in Beijing Chaoyang District, selected by convenience sampling. The questionnaire included general information of participants and the revised CARE measure. The results of the survey were analyzed for the reliability and validity of Chinese version of CARE measure.Results:In the culture adaptation stage, 30 word-changes and 13 phrase-changes were made to improve the cultural adaptation of CARE. A total of 373 valid questionnaires were were collected with a valid recovery rate of 100.0%. The participants had a mean age of (60.8±13.12) years, with females of 68.6% (256/373), junior high school or high school education of 58.7% (219/373), and retirees of 71.3% (266/373). The results showed that there was a significant difference in scores of each item between the high group (top 27%) and the low group (bottom 27%) ( P<0.001). There was a positive correlation between each item and the total score, with a correlation coefficient between 0.817 and 0.868 ( P<0.001). The reliability analysis results show that the Cronbach′s α of the revised CARE was 0.960. In the content validity analysis, among the 10 items, the proportion of patients who considered the item "not applicable" was between 1.1% and 4.8%, and the proportion who considered the item "important" was between 92.8% and 96.2%. In exploratory factor analysis, KMO=0.944 and Bartlett′s sphericity test P<0.001. One common factor with an eigenvalue>1 was extracted, and the cumulative variance explained by which was 73.85%, with the load value of each item of 0.815-0.909. Conclusion:The revised Chinese version of CARE measure shows good reliability and validity and it can be applied in primary care settings for Mandarin speaking population.

Objective:To analyze the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Methods:This retrospective cohort study utilized data from the Beijing Birth Cohort database established by Beijing Obstetrics and Gynecology Hospital, Capital Medical University. A total of 73 193 pregnant women who underwent regular prenatal examinations and delivered at the hospital between January 2018 and December 2023 were consecutively included. From 2018 to 2020, all participants received nutrition education, and high-risk pregnancies predisposed to macrosomia were referred to nutrition clinics for further follow-up. From 2021 to 2023, obstetricians participated in nutritional assessments and gestational weight gain guidance, with repeated nutrition evaluations and education provided during early, mid, and late pregnancy. A multidisciplinary team (obstetrics and nutrition departments) collaborated to implement an enhanced nutrition management model for all pregnant women. General data, parity, gestational age at delivery, neonatal birth weight, and clinical information were collected. Annual incidences of macrosomia and low birth weight were calculated. Chi-square tests and variance analysis were used to analyzed yearly changes in macrosomia rates and evaluate the impact of the two-phase management strategies on macrosomia incidence, thereby to explore the validity of an enhanced nutrition management model for all pregnant women in reducing the incidence of macrosomia.Results:The number of deliveries included annually from 2018 to 2023 was 14 578, 15 413, 11 496, 11 146, 10 396, and 10 164, respectively. Maternal pre-pregnancy body mass indices in 2022 to 2023 were higher than those in 2018 to 2021 [(22.26±3.50) and (22.23±3.65) vs (21.87±3.27), (21.82±3.31), (21.86±3.34) and (21.94±3.39) kg/m2, respectively (all P<0.05)]. Neonatal birth weights in 2021 to 2022 were lower than those in 2018 to 2020 [(3 271±514) and (3 270±513) vs (3 323±504), (3 314±500), and (3 315±510) g], and the birth weight in 2023 was further reduced compared to that in 2018 to 2022 [(3 236±506) vs (3 323±504), (3 314±500), (3 315±510), (3 271±514) and (3 270±513) g] (all P<0.05). The incidence of macrosomia in 2021 to 2022 was lower than those in 2018 to 2020 (5.55%, 5.75% vs 6.97%, 6.68%, 6.67%), and the incidence in 2023 further decreased compared to those in 2018 to 2022 (4.16% vs 6.97%, 6.68%, 6.67%, 5.55%, 5.75%) (all P<0.05). Conclusion:The enhanced nutrition management model for all pregnant women effectively reduces the incidence of macrosomia, demonstrating significant clinical value for widespread implementation.

The study was a prospective observational study. A total of 24 patients who underwent maintenance hemodialysis (MHD) at Haidian Hospital in Beijing from May 2024 to June 2024 were included as the study subjects. The safety and efficacy of a new single-needle dialysis in MHD patients were evaluated. The reasons for using single-needle dialysis included waiting for the maturity of internal fistula(7 cases, 29.17%), autogenous arteriovenous fistula thrombosis occurred (6 cases, 25.00%), puncture difficulty occurred (7 cases, 29.17%), and pain sensitivity or elderly (4 cases, 16.67%). The results showed that the average blood flow was (155.65±5.90) ml/min, total blood volume was (35.92±2.65) L during single-needle dialysis. One patient had slight puncture leakage, and the puncture success rate was 95.83%. Relevant indicators of dialysis adequacy showed that the average urea clearance (Kt/V) was 0.90±0.42, urea reduction ratio was 58.31%±7.93%, and online real-time Kt/V monitoring average value was 0.98±0.55. The results suggest that the application of the new improved single-needle dialysis mode in MHD patients is safe and effective.

Objective:To evaluate the efficacy of modified splenic arteriovenous shunt surgery at the distal pancreatic tail in combined pancreas-kidney transplantation.Methods:A retrospective analysis was conducted on 24 recipients who underwent combined pancreas-kidney transplantation with the modified splenic arteriovenous shunt at the pancreatic tail from November 2023 to October 2024 (shunt group) and 231 recipients who received conventional splenic artery and vein ligation since 2016 (ligation group). The incidence of perioperative thrombosis and severe adverse events was compared between the two groups using the chi-square test or Fisher's exact test. Independent sample t-tests were performed to assess postoperative pancreatic and renal function recovery as well as blood perfusion in 15 recipients from the shunt group and 20 from the ligation group who underwent CT perfusion imaging (CTP).Results:The incidence of perioperative splenic arteriovenous thrombosis was lower in the shunt group (0) compared to the ligation group (4.76%, 11/231), though the difference was not statistically significant ( P=0.606). One month postoperatively, the shunt group demonstrated significantly lower serum amylase levels than the ligation group (99.61±19.62 vs. 148.20±70.67 U/L, P=0.018). However, at the time of CTP examination, serum lipase (67.87±32.35 vs. 45.11±17.94 U/L, P=0.014) and creatinine levels (131.79±26.41 vs. 112.1±24.98 μmol/L, P=0.034) were significantly higher in the shunt group. Urea nitrogen levels were also significantly higher in the shunt group both one month postoperatively (11.24±4.64 vs. 8.51±3.01 mmol/L, P=0.043) and at the CTP examination (10.41±1.78 vs. 6.87±1.91 mmol/L, P=0.001). Regarding pancreatic perfusion, blood volume in both the pancreatic head (15.99 ± 3.51 vs. 20.67 ± 5.47 ml/100 g, P = 0.024) and tail (17.19±4.24 vs. 27.40±19.80 ml/100 g, P=0.039) was significantly lower in the shunt group. After one minute of splenic artery perfusion, the shunt group exhibited significantly higher splenic artery blood flow (755.85±101.50 vs. 574.00 ± 142.06 ml·min -1· (100 g) -1, P<0.001) and blood volume (58.90 ±19.93 vs. 23.21±17.02 ml/100 g, P=0.007) compared to the ligation group. These differences persisted after two minutes of perfusion (blood flow: 793.83±68.57 vs. 503.78 ± 130.80 ml·min -1· (100 g) -1, P<0.001; blood volume: 64.22±15.74 vs. 34.32±20.39 ml/100 g, P=0.002). For the transplanted kidney, the shunt group had significantly lower blood flow (113.10±28.55 vs. 232.76±113.37 ml·min -1· (100 g) -1, P<0.001), blood volume (28.95±10.79 vs. 38.36±12.38 ml/100 g, P=0.047), and capillary surface permeability (PS) (26.49±16.57 vs. 43.02±20.37, P = 0.042) in the upper pole. Similar reductions in blood flow, blood volume, and PS were observed in the middle dorsal region ( P=0.018, 0.021, and 0.048, respectively) and lower pole ( P<0.001, P=0.048, and P=0.012, respectively). Conclusion:The modified splenic arteriovenous shunt at the pancreatic tail appears to be a safe and effective approach to reducing the risk of pancreatic graft thrombosis. This technique facilitates effective diversion of pancreatic parenchymal blood flow into the splenic vein, alleviating hyperperfusion of the transplanted pancreas. While renal blood perfusion was reduced postoperatively, it did not adversely affect renal function.

OBJECTIVE: To discuss the elbow skin fold extension line in Kirschner wire internal fixation of extended supracondylar humeral fractures in children. METHODS: The clinical data of 58 children with extended supracondylar fractures of the humerus who met the selection criteria between August 2021 and July 2024 were retrospectively analyzed. In 28 cases, needle placement of medial epicondyle of humerus was performed with the assistance of the elbow skin fold extension line (study group), and 30 cases were assisted by routine touch of the medial epicondyle of the humerus (control group). There was no significant difference in baseline data such as gender, age, side, cause of injury, Gartland type, Kirschner wire configuration, and time from injury to operation between the two groups ( P>0.05). The closed reduction rate, total operation time, time of medial humeral condyle pin placement, fluoroscopy times during medial pin placement, rate of one-time determination of medial entry point, ulnar nerve injury incidence, and fracture healing time were recorded and compared between the two groups. At the same time, the closed reduction rate of patients with the time from injury to operation ≤24 hours and >24 hours was compared. The elbow function was evaluated by Mayo elbow function score. RESULTS: The closed reduction rate of the study group was significantly higher than that of the control group ( P<0.05). Among all patients, the closed reduction rate of patients with the time from injury to operation ≤24 hours [73.3% (22/30)] was significantly higher than that of patients >24 hours [42.9% (12/28)] ( χ ²=5.545, P=0.019). The total operation time, medial needle placement time, and fluoroscopy times in the study group were significantly less than those in the control group, and the one-time determination rate of medial needle entry point in the study group was significantly higher than that in the control group ( P<0.05). There were 4 cases of ulnar nerve injury in the control group, and no ulnar nerve injury in the study group, but there was no significant difference in the incidence of ulnar nerve injury between the two groups ( P>0.05). All patients were followed up 6-12 months (mean, 8 months). There was no bone nonunion in both groups, and the fracture healing time of the study group was significantly shorter than that of the control group ( P<0.05). Volkmann ischemic contracture, heterotopic ossification, myositis ossificans, and premature epiphyseal closure were not observed after operation. No complications such as loosening or fracture of Kirschner wire occurred. At last follow-up, the Mayo elbow joint function score was used to evaluate function, and there was no significant difference between the two groups ( P>0.05). CONCLUSION In the treatment of extended supracondylar fractures of the humerus in children, the elbow skin fold extension line can help to quickly locate the medial epicondyle of the humerus, quickly insert Kirschner wire, and reduce the operation time and trauma.
