OBJECTIVE: To investigate effectiveness of arthroscopic superior capsular reconstruction using a "sandwich" patch combined with platelet-rich plasma (PRP) injection in treating massive irreparable rotator cuff tears. METHODS: A clinical data of 15 patients (15 sides) with massive irreparable rotator cuff tears, who were admitted between September 2020 and March 2023 and met the selective criteria, was retrospectively analyzed. There were 8 males and 7 females with an average age of 62.1 years (range, 40-80 years). The rotator cuff tears were caused by trauma in 7 cases and other reasons in 8 cases. The disease duration ranged from 5 to 25 months, with an average of 17.7 months. According to the Hamada grading, the rotator cuff tears were rated as grade 1 in 2 cases, grade 2 in 8 cases, and grade 3 in 5 cases. All patients were underwent superior capsular reconstruction using the "sandwich" patches (autologous fascia lata+polypropylene patch+autologous fascia lata) combined with PRP injection on patches. The pre- and post-operative active range of motion (ROM) of the shoulder joint, American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, University of California, Los Angeles Shoulder Rating Scale (UCLA) score, and visual analogue scale (VAS) score were recorded. The subacromial space was measured on the imaging and rotator cuff integrity was assessed based on Sugaya grading. RESULTS: All incisions healed by first intention after operation without any complications such as infection. All patients were followed up 12-18 months (mean, 14.4 months). At last follow-up, the active ROMs of flexion, abduction, external rotation, internal rotation of the shoulder joint, subacromial space, ASES score, Constant-Murley score, and UCLA score increased, and VAS score decreased, showing significant differences when compared with preoperative values ( P<0.05). There was no significant difference in the Sugaya grading between last follow-up and immediately after operation ( P>0.05). CONCLUSION For massive irreparable rotator cuff tears, arthroscopic superior capsular reconstruction using the "sandwich" patches combined with PRP injection can restore stability of the shoulder joint, relieve pain, promote rotator cuff healing, and achieve good short-term effectiveness.

OBJECTIVE: To investigate the effect and mechanism of Hyssopus cuspidatus Boriss. extract (HCE) in ovalbumin (OVA)-induced allergic asthma. METHODS: Components identification of HCE was conducted using ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry. Mice were sensitized with OVA to establish asthmatic model, and dexamethasone was used as positive control. Respiratory reactivity, white cells counting in bronchoalveolar lavage fluid and peripheral blood, cytokine level measurement in serum and lung tissue, and histologic examination were performed to evaluate the therapeutic effect of HCE on asthma. Network pharmacology approach was used for mechanism prediction. Western blotting and untargeted lipidomics method were applied for mechanism validation. RESULTS: Fifty-two compounds were identified in HCE, predominantly terpenoids and flavonoids. HCE markedly reduced airway resistance, the eosinophil infiltration in lung tissues, and the levels of immunoglobulin E, interleukin-4, interleukin-5, and interleukin-13. Network pharmacology analysis suggested phosphatidylinositol 3-kinases (PI3K), c-Jun N-terminal kinase (JNK), and p38 Mitogen-activated protein kinase (p38 MAPK) may be key proteins of HCE in the treatment of allergic asthma. Western blot results indicated that the levels of phosphorylated PI3K, JNK, and P38 were downregulated in HCE-treated group. Moreover, HCE significantly upregulated the levels of ceramide and sphingomyelin and downregulated the level of phosphatidylcholine. CONCLUSION HCE inhibited allergic asthma via PI3K/JNK/P38 signaling pathway and lipid homeostasis regulation.

OBJECTIVE: To explore effectiveness of arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique in the treatment of recurrent anterior dislocation of shoulder joint. METHODS: A clinical data of 14 patients with recurrent anterior dislocation of shoulder joint and glenoid bone defect, who were met the selective criteria and admitted between February 2021 and February 2022, was retrospectively analyzed. All patients were treated with arthroscopic Eden-Hybinette procedure and the bone blocks were fixed by using Triple-Pulley and four point anti-rotation fixation technique. There were 9 males and 5 females with an average age of 31.2 years (range, 22-40 years). Shoulder dislocation occurred 4-10 times (mean, 6.8 times). The time from the initial dislocation to the admission was 1-6 years (mean, 3.3 years). The Instability Severity Index Score (ISIS) was 7.2±0.8, the Beighton score was 2.9±2.4, and the width ratio of glenoid bone defect was 26.64%±1.86%. Pre- and post-operative visual analogue scale (VAS) score, the University of Califonia-Los Angeles (UCLA) shoulder score, Constant score, and American Association of Shoulder and Elbow Surgeons (ASES) score were used to evaluate shoulder pain and function. The position, healing, resorption, and remodeling (glenoid area) of the bone blocks were evaluated by CT of shoulder joint. RESULTS: All patients underwent surgery successfully without any serious complications. All patients were followed up 11.5-13.8 months (mean, 12.0 months). The VAS scores of shoulder joint after operation decreased compared to preoperative levels, while the UCLA score, Constant score, and ASES score all increased, with significant differences ( P<0.05). And with the prolongation of time, the above indicators further improved, and the differences between different time points were significant ( P<0.05). Imaging reexamination showed that the bone block completely filled the glenoid defect, with good position and no significant displacement. Over time, the bone block healed and partially absorbed and remodelled. The postoperative glenoid area increased significantly compared to preoperative area ( P<0.05). With the prolongation of time, the glenoid area significantly decreased, but the difference was not significant between different time points ( P>0.05). CONCLUSION For the recurrent anterior dislocation of shoulder joint, Triple-Pulley and four point anti-rotation fixation technique in Eden-Hybinette procedure can effectively prevent bone rotation, make fixation more reliable, and easy to operate and achieve good effectiveness.

  Objective  To understand the current status of surgical treatment for hemophilia osteoarthropathy (HO) in China.  Methods  Using an online questionnaire, select domestic hospitals that partici-pated in the compilation of the 'Guideline for perioperative management of hemophilia patients undergoing orthopaedic surgery in China ', in addition to members of the National Joint Surgery Group, and the Orthopedic Branch of the Chinese Medical Association for targeted investigation and analysis.  Results  A total of 17 domestic hospitals were included, all of which were general hospitals. Hospitals that started HO surgery treatment before 2000 accounted for 35.29%. A total of 3057 surgical cases of HO were reported by those hospitals. The most commonly performed surgical procedures were hip and knee joint replacement. The most commonly used coagulation factor replacement regimen was recombinant coagulation factor preparation. Ten hospitals reported finding patients with transfusion-related infectious diseases. Bleeding and hematoma formation were the most frequently reported surgical complications. Excessive length of hospital stay and high economic costs were the most frequently reported problems.  Conclusions  Surgical treatment for HO in 17 hospitals is mainly carried out in some large comprehensive medical centers in the eastern region. Compared with the patient base, the popularity and number of surgeries are still relatively insufficient. It is necessary to further standardize the treatment system by standardizing factor replacement and strengthening rehabilitation to improve surgical treatment outcomes.

Objective    To investigate the surgical strategies and clinical efficacy of transmitral septal myectomy in the treatment of recurrent left ventricular outflow tract obstruction (LVOTO) after alcohol septal ablation. Methods    The clinical data of patients with recurrent LVOTO after alcohol septal ablation from July 2020 to July 2021 in the Department of Cardiac Surgery, Guangdong Provincial People's Hospital were retrospectively analyzed. Patients were preoperatively evaluated by echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography, 3D modeling and printing technology. A personalized surgical strategy was preoperatively developed according to multimodality imaging assessment, while visual exploration was performed on the digital model and simulated surgical resection was performed on the printed model. Results     Two female patients were enrolled, aged 62 years and 64 years, respectively. Totally endoscopic transmitral extended myectomy was successfully performed on both patients with aortic cross-clamping time of 96 min and 85 min, respectively. LVOTO was relieved immediately (subaortic peak pressure gradient decreased from 100 mm Hg to 4 mm Hg and from 84 mm Hg to 6 mm Hg, respectively) and the mitral regurgitation significantly improved after the procedure. No patient had complete atrioventricular block or required permanent pacemaker implantation. The patients were discharged uneventfully without postoperative complications. Conclusion    Personalized totally endoscopic transmitral extended myectomy combined with multimodality imaging assessment and 3D modeling and printing has an acceptable clinical effect in patients with recurrent LVOTO after alcohol septal ablation. The procedure can precisely resect the hypertrophic septal myocardium while avoiding serious complications such as septal perforation or complete atrioventricular block.

In order to further strengthen the training and management of clinical teachers, broaden the career development channels of clinical teachers, and truly stimulate their teaching enthusiasm and initiative, this study further classifies clinical teachers according to the principle of the Snell model, focuses on the training of educational clinicians, and explores the training mechanism of teaching talents in line with the actual development needs of hospitals affiliated to universities from the aspects of selection, training, incentive, and assessment. The results of practice show that related practices have a good effect, and the mean number of teaching achievements was 1.98 for the 56 educational physicians, which was 3.9 times that for non-educational physicians. The per capita teaching achievements of educational physicians tended to increase every year compared with those of non-educational physicians. The training path for educational physicians provides useful experience for the construction of clinical teaching team and the high-quality development of education and teaching, and at the same time, it is necessary to further strengthen the dynamic adjustment of talent echelon, the improvement of operating mechanism, and the introduction of new technology.

Objective:To investigate the perioperative total blood loss of robot-assisted total knee arthroplasty (TKA).Methods:A total of 60 patients with knee osteoarthritis who underwent initial unilateral TKA in Peking Union Medical College Hospital from February to June 2022 were retrospectively analyzed. According to whether they received robot-assisted surgery, they were divided into robot-assisted group and traditional surgery group. In the robot-assisted group, there were 32 patients, including 6 males and 26 females, aged 70.22±5.88 years (range, 57 to 79 years). Left side 14 cases, right side 18 cases; grade of Kellgren-Lawrence: 1 case of grade Ⅱ, 14 cases of grade Ⅲ, 17 cases of grade Ⅳ. In the traditional surgery group, there were 28 patients, including 5 males and 23 females, aged 68.61±6.79 years (range, 57 to 87 years). Left side 16 cases, right side 12 cases; grade of Kellgren-Lawrence: 2 cases of grade Ⅱ, 12 cases of grade Ⅲ, 14 cases of grade Ⅳ. There was no significant difference in baseline data between the two groups ( P>0.05). Postoperative hemoglobin, hematocrit, and their decreased values were recorded in the two groups, and perioperative range of motion (ROM) of knee and Hospital for Special Surgery (HSS) scores were compared between the two groups. Results:All patients successfully completed the surgery and were followed up, with a follow-up time of 9.93±0.83 months (range, 8-11 months) in the robotic-assisted group and 9.59±0.97 months (range, 8-11 months) in the traditional surgery group. The application time of tourniquet in the robot-assisted group was 96.19±10.21 min, which was higher than that in the traditional surgery group (62.68±16.54 min), and the difference was statistically significant ( t=9.57, P<0.001). The total perioperative blood loss in the robot-assisted group was 534.59(411.85, 859.26) ml, which was higher than 411.32(313.42, 613.52) ml in the traditional surgery group, and the difference was statistically significant ( Z=-2.37, P=0.018). There were no significant differences in hemoglobin or hematocrit between the two groups at day 1 and 3 after surgery ( P>0.05). The hemoglobin decrease value in the robotic-assisted group was 19.63±9.73 g/L, which was greater than 14.71±5.84 g/L in the traditional surgery group, and the difference was statistically significant ( t=2.40, P=0.020). The decrease value of hematocrit in the robot-assisted group was 5.77%±3.14%, which was greater than 4.09%±1.57% in the traditional operation group ( t=2.56, P=0.013). At the last follow-up, knee ROM of the two groups were 123.03°±5.91° and 125.82°±6.59°, respectively, which were higher than the preoperative values of 95.69°±11.64° and 90.29°±23.08°. Postoperative HSS scores were 89.50±4.19 points and 90.70±4.34 points, which were higher than 62.58±10.52 points and 61.09±12.66 points before operation, the differences were statistically significant ( P<0.05), and there was no significant difference between groups ( P>0.05). There were 6 cases of postoperative deep vein thrombosis of the lower extremities in the robot-assisted group and 2 cases in the traditional surgery group, and the difference was not statistically significant (χ 2=0.88, P=0.348). Conclusion:Compared with traditional TKA, robotic-assisted TKA increased perioperative blood loss, and there was no difference in postoperative knee function between the two groups.

Objective:To explore the effect of multiple integration correction training for articulation disorder in children with functional alalia disorders (FAD) .Methods:From January 2020 to June 2021, 68 children with FAD who received language function training in the Affiliated Huaian First People 's Hospital of Nanjing Medical University were selected by convenience sampling. The children were divided into control group and observation group with the method of random number table, 34 cases each. The control group received routine speech training, while the observation group received multiple integration correction training for articulation disorder on the basis of the control group. The motor function of articulation organs, articulation syllable assessment results and speech function recovery were compared between the two groups before intervention (T1) , three months after intervention (T2) and six months after intervention (T3) . Results:After intervention, the longest articulation time, head control, lip strength, tongue extension range, left and right lip swing power of the observation group were higher than those of the control group, with statistical differences ( P<0.05) . At T1, T2 and T3, there were interaction, inter group and time effects in the assessment results of articulation syllables of children in the two groups, and the differences were statistically significant ( P<0.05) . The scores of the modified Frenchay Dysarthria Assessment (FDA) in the two groups had interaction, inter group and time effects, and the differences were statistically significant ( P<0.05) . Conclusions:In FAD children, the implementation of multiple integration correction training for articulation disorder can improve the motor function of articulation organs and the ability of articulation syllable repetition, thereby promoting the recovery of the children's speech function.
