Based on advancements in modern medical research regarding the intricate connection between the endocrine and exocrine functions of the pancreas， as well as the relationship between pancreatic functions and traditional Chinese medicine （TCM） spleen system， this paper discussed the categorization of the pancreas. It is proposed that the pancreas is neither a true zang organ nor a fu organ， but possessed the attributes of an extraordinary fu-organ and can be classified under the spleen. The spleen governs transportation and transformation， ascent of the clear and dispersion of essence， which encompasses the endocrine and exocrine functions， and pancreatic enzymes and glucose-regulating hormones form the material basis for the spleen's function of dispersing essence. Diseases of the pancreas exhibit characteristics of both zang-organ deficiency and fu-organ excess， so treatment should simultaneously supplement zang-organ disease and regulate fu-organ disease when pancreas showing endocrine and exocrine co-morbidities， with focus on restoring the pancreas （spleen）'s dispersing essence function. Therapeutic strategies include supplementing spleen qi， nourishing spleen yin to strengthen spleen earth， unblocking spleen collaterals， raising spleen yang， and removing spleen turbidity to support the spleen's dispersing essence function， so as to replenish the essential qi of zang-fu organs， ensure their distribution throughout the body， and improve the endocrine and exocrine functions of the pancreas.

Right atrial diverticulum is a rare congenital cardiac malformation with a very low incidence and few reports in the literature. It is a sac-like structure originating from the free wall of the right atrium or the right auricle，and the wall of the diverticulum is mostly composed of normal myocardial tissue. Patients with diverticulumare asymptomatic in the early stage of the disease，and it is mostly detected by imaging examinations. The patient was a 96-year-old male admitted to the Second Hospital of Hebei Medical University with intermittent chest tightness，shortness of breath，and dizziness for more than half a month. Echocardiography and contrast echocardiography were performed 1 d after the patient was admitted to the hospital，suggesting the diagnasis of right atrial diverticulum with thrombosis，and coronary CT angiography was performed 4 d after the patient was admitted to the hospital，which considered right atrial diverticulum，with an internal filling defect，and suspected thrombus formation. The patient was older and did not receive further diagnosis and treatment，and cardiac ultrasound was repeated 1 month later，with no significant change in the size and morphology of the mass within the right atrial diverticulum. By analyzing in detail a case with right atrial diverticulum initially misdiagnosed as pericardial effusion，this article aimed to raise cardiac sonographers' awareness of the diagnosis of right atrial diverticulum and to explore the key role of cardiac acoustic contrast technology in cardiac ultrasound diagnosis.

Objective:To compare the clinical outcomes and costs in arthroscopic repair of small and medium-sized supraspinatu tendon tears between double-pulley suture-bridge (DPSB) and traditional suture bridge (SB).Methods:A retrospective study was conducted at Department of Joint Surgery, The Second Hospital Affiliated to Hengyang Medical School to analyze the data of 26 patients with small and medium-sized supraspinatus tendon tears who had been treated by SB repair from May 2018 to December 2020 (SB group) and those of 35 patients with small and medium-sized supraspinatus tendon tears who had been treated by DPSB repair from January 2021 to December 2022 (DPSB group). There were 61 patients in the 2 groups, including 44 males and 17 females, with an age of (59.1±7.5) years. The left shoulder was affected in 26 patients and the right shoulder in 35 patients. The tear size was small in 25 cases and medium in 36 ones. The total number of anchors used, total anchoring costs, and surgical time were recorded and compared between the 2 groups. Visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score and shoulder range of motion were used to evaluate the clinical outcomes of the 2 groups before surgery and at the last follow-up. Comparisons were made within and between the 2 groups. Tendon integrity was assessed using MRI or ultrasound at 3, 6, 12 months or at the last follow-up.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). DPSB and SB groups were followed up for (28.1±3.5) and (27.1±1.8) months, respectively. There was no statistically significant difference between DPSB group and SB group in surgical time or total number of anchors ( P>0.05). The total costs of anchoring in DPSB group [(6,028.6±173.4) yuan] were significantly lower than those in SB group [(13,257.1±554.2) yuan] ( P<0.05). At the last follow-up, the anterior flexion, abduction, external rotation and internal rotation of the shoulder, as well as VAS pain score, ASES score and UCLA score, were significantly better in both DPSB group and SB group than their preoperative values ( P<0.05), but there were no statistically significant differences between DPSB group and SB group ( P>0.05). There was no significant difference either in tendon retear between DPSB group (2 cases) and SB group (1 case) ( P>0.05). No such complication as wound infection or nerve damage was found in either group. Conclusions:In arthroscopic repair of small and medium-sized supraspinatu tendon tears, both DPSB and SB techniques can achieve satisfactory and comparable clinical outcomes. However, DPSB leads to lower total costs of anchoring.

OBJECTIVE: To describe a novel arthroscopic technique of modified tri-anchor double-pulley suture-bridge in repairing medium-sized supraspinatus tendon tears and evaluate the early effectiveness. METHODS: Between June 2021 and January 2024, 26 patients with medium-sized supraspinatus tendon tears who underwent arthroscopic modified tri-anchor double-pulley suture-bridge repair and met the selective criteria were included. There were 11 males and 15 females with an average age of 61.4 years (range, 43-74 years). Five patients had a significant history of trauma, while the remaining 21 patients had no apparent cause. The time from symptom onset to hospitalization was 3-25 months (mean, 7.9 months). The effectiveness was evaluated during follow-up, including the scores of University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES), visual analogue scale (VAS), the range of forward flexion, abduction, external rotation, and internal rotation, and patient's satisfaction. Either MRI or ultrasound examination were used to evaluate structural integrity of the tendon. RESULTS: The operation time was 65-110 minutes (mean, 81.8 minutes). All patients were followed up 12-43 months (mean, 23.0 months). At 3 and 12 months after operation, the shoulder range of flexion, abduction, external rotation, and internal rotation, and the scores of VAS, UCLA, and ASES significantly improved when compared with those before operation ( P<0.05). The improvement was further observed at 12 months compared to 3 months ( P<0.05). At last follow-up, 13 patients were very satisfied with the effectiveness, 11 patients were satisfied, 1 was relatively satisfied, and 1 was dissatisfied. During follow-up, 15 patients underwent imaging examination and imaging reexamination showed that the re-tear rate of tendon was 6.6%(1/15). The remaining 11 patients refused imaging examination. Complications included partial anchor withdrawal in 1 case, shoulder stiffness in 5 cases, and mild pain in shoulder joint in 2 cases in physical activity or heavy physical activity. CONCLUSION Arthroscopic modified tri-anchor double-pulley suture-bridge technique is a novel surgical technique that uses double-loaded suture anchors as medial- and lateral-row anchors. In repairing medium-sized supraspinatus tendon tears, 6 sets of double-pulley suture-bridges can be created from one medial-row anchor; knotless medial-row can reduce re-tear rate of the tendon; good early effectiveness is obtained.

OBJECTIVE: To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears. METHODS: A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up. RESULTS: All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%). CONCLUSION Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.
