OBJECTIVE: To investigate the current status of long-term quality of life in patients with severe acute pancreatitis (SAP) who have been cured and discharged, and to analyze the influencing factors affecting long-term quality of life in SAP cured patients after discharge. METHODS: A retrospective collection was conducted. Patients who were received standardized treatment before being cured and discharged from the hospital admitted to the first department of critical care medcine of the Second Affiliated Hospital of Anhui Medical University from January 2017 to December 2023 were enrolled. According to the 36-item short form health survey scale (SF-36) score, patients were divided into high score group (high quality of life, the top 50% of patients with total SF-36 score) and low score group (low quality of life, the bottom 50% of patients with total SF-36 score). The gender, age, history of hypertension and diabetes, etiology of pancreatitis, acute physiology and chronic health evaluation II (APACHE II), sequential organ failure assessment (SOFA), CT severity index (CTSI), laboratory indicators such as C-reactive protein (CRP), procalcitonin (PCT), blood glucose, and triglycerides upon admission, use of vasoactive drugs, non-invasive/high-flow ventilation, invasive ventilation, retroperitoneal puncture and drainage, open pancreatic surgery treatment and secondary infection during hospitalization were collected, as well as the retention of abdominal drainage tubes at discharge from hospital. Distribute follow-up questionnaires or telephone follow-up surveys through WeChat and Question Star programs to investigate the pancreatic secretion function, chronic abdominal pain, and recurrence of pancreatitis of patients after discharge. Multivariable Logistic regression was used to analyze the relevant factors affecting the long-term quality of life of cured patients with SAP. RESULTS: A total of 86 patients were ultimately enrolled. There were 43 patients in both the high and low score groups. Among 86 patients, 20 experienced acute pancreatitis recurrence, with a recurrence rate of 23.26%. Twenty-two (25.58%) experienced chronic abdominal pain after discharge, and 5 patients (5.81%) needed medication to relieve pain. Thirty-three patients (38.37%) had pancreatic exocrine dysfunction after discharge, characterized by abdominal distension, constipation or diarrhea. Twenty-two patients (25.58%) suffered from pancreatic endocrine dysfunction, and were diagnosed with diabetes. Univariate analysis showed that compared with the high score group, the low score group had more patients with hypertension, initial renal dysfunction, initial severe metabolic acidosis, initial serum calcium < 2.0 mmol/L, blood glucose > 11.1 mmol/L and cultured Gram positive bacteria (from blood/body fluid/pancreatic necrotic tissue) during treatment (48.84% vs. 16.28%, 60.47% vs. 32.56%, 18.60% vs. 4.65%, 88.37% vs. 62.79%, 55.81% vs. 30.23%, 34.88% vs. 13.95%), had higher CTSI score (6.60±1.61 vs. 5.77±1.32), lower hemoglobin level at discharge (g/L: 102.30±18.78 vs. 110.72±16.68), and a lower proportion of etiological interventions after discharge (34.88% vs. 67.44%), the differences were statistically significant (all P < 0.05). Multivariate Logistic regression analysis showed that hypertension [odds ratio (OR) = 4.814, 95% confidence interval (95%CI) was 1.196-19.378], initial serum calcium < 2.0 mmol/L (OR = 6.688, 95%CI was 1.321-33.873) and initial blood glucose > 11.1 mmol/L (OR = 6.473, 95%CI was 1.399-29.950) were risk factors for long-term quality of life in cured SAP patients (all P < 0.05), while post discharge prophylactic intervention was a protective factor for long-term quality of life (OR = 0.092, 95%CI was 0.020-0.425, P < 0.01). CONCLUSIONS Cured SAP patients have varying degrees of impaired secretion function and the possibility of recurrence of acute pancreatitis. Hypertension, initial serum calcium < 2.0 mmol/L and blood glucose > 11.1 mmol/L are independent influencing factors for low long-term quality of life in cured SAP patients. Prevention and intervention targeting the etiology of pancreatitis after discharge can improve the long-term quality of life of cured SAP patients.

The COVID-19 epidemic has spread to the whole world for three years and has had a serious impact on human life, health and economic activities. China's epidemic prevention and control has gone through the following stages: emergency unconventional stage, emergency normalization stage, and the transitional stage from the emergency normalization to the "Category B infectious disease treated as Category B" normalization, and achieved a major and decisive victory. The designated hospitals for prevention and control of COVID-19 epidemic in Tianjin has successfully completed its tasks in all stages of epidemic prevention and control, and has accumulated valuable experience. This article summarizes the experience of constructing a hospital infection prevention and control system during the "Category B infectious disease treated as Category A" period in designated hospital. The experience is summarized as the "Cluster" hospital infection prevention and control system, namely "three rings" outside, middle and inside, "three districts" of green, orange and red, "three things" before, during and after the event, "two-day pre-purification" and "two-director system", and "one zone" management. In emergency situations, we adopt a simplified version of the cluster hospital infection prevention and control system. In emergency situations, a simplified version of the "Cluster" hospital infection prevention and control system can be adopted. This system has the following characteristics: firstly, the system emphasizes the characteristics of "cluster" and the overall management of key measures to avoid any shortcomings. The second, it emphasizes the transformation of infection control concepts to maximize the safety of medical services through infection control. The third, it emphasizes the optimization of the process. The prevention and control measures should be comprehensive and focused, while also preventing excessive use. The measures emphasize the use of the least resources to achieve the best infection control effect. The fourth, it emphasizes the quality control work of infection control, pays attention to the importance of the process, and advocates the concept of "system slimming, process fattening". Fifthly, it emphasizes that the future development depends on artificial intelligence, in order to improve the quality and efficiency of prevention and control to the greatest extent. Sixth, hospitals need to strengthen continuous training and retraining. We utilize diverse training methods, including artificial intelligence, to ensure that infection control policies and procedures are simple. We have established an evaluation and feedback mechanism to ensure that medical personnel are in an emergency state at all times.

Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.

Objective:To revise and evaluate the reliability and validity of the Healthcare Provider Perceptions of Team Effectiveness (Provider-PTE) .Methods:The English version of the Provider-PTE was translated literally and back in accordance with the Brislin translation principles. Questionnaire culture debugging and item revision were conducted through Delphi method and pre-survey. In March 2022, a survey was conducted among 641 nurses from two ClassⅢ Grade A hospitals in Qingdao to test the reliability and validity of the questionnaire. A total of 641 questionnaires were distributed, and 605 valid questionnaires were recovered, with an effective recovery rate of 94.4%.Results:The Chinese version of Provider-PTE included five dimensions, including role development, team support, team meetings, team operations, and care outcomes, with a total of 26 items. Through exploratory factor analysis, the cumulative variance contribution rate of the five common factors was 84.783%. The average scale content validity index of the Provider-PTE was 0.928, and the item content validity index was 0.875 to 1.000. The Cronbach's α coefficient of the Chinese version of Provider-PTE was 0.859, and the retest reliability was 0.873.Conclusions:The Chinese version of Provider-PTE has good reliability and validity, and can be used to assess the team effectiveness of nursing staffs.

OBJECTIVE: To compare the effectiveness of open reduction of posterior cruciate ligament (PCL) avulsion fracture at tibial insertion of knee joint with absorbable screws fixation and absorbable screw combined with suture anchor fixation. METHODS: The clinical data of 26 patients with PCL avulsion fracture at tibial insertion who met the selection criteria between March 2015 and October 2021 were retrospectively analyzed. Among them, 14 patients were fixed with simple absorbable screw (group A), and 12 patients were fixed with absorbable screw combined with suture anchors (group B). All patients were confirmed by X-ray film, CT, or MRI preoperatively, and got positive results in preoperative posterior drawer tests. There was no significant difference in gender, age, side of affected limb, time from injury to operation, comorbidities, and preoperative Meyers & McKeever classification, Lysholm score, and International Knee Documentation Committee (IKDC) score between the two groups ( P>0.05). The operation time and postoperative complications were recorded and compared between the two groups. At last follow-up, Lysholm score and IKDC score were used to evaluate the improvement of knee function. RESULTS: There was no significant difference in operation time between the two groups ( P>0.05). All incisions healed by first intention, and no complication such as vascular and nerve injury or venous thrombosis occurred. All 26 patients were followed up 9-89 months, with an average of 55.3 months. The follow-up time of group A and group B was (55.7±23.2) and (56.8±29.3) months, respectively, with no significant difference ( t=-0.106, P=0.916). Radiographs showed bone healing in both groups at 3 months after operation, and no complication such as infection and traumatic arthritis occurred. At last follow-up, the posterior drawer test was negative in both groups, and the Lysholm score and IKDC score significantly improved when compared with the pre-operative values ( P<0.05). However, there was no significant difference in the improvement value between the two groups ( P>0.05). CONCLUSION For PCL avulsion fracture at tibial insertion of the knee joint, the open reduction and absorbable screw combined with suture anchor fixation can achieve reliable fracture reduction and fixation, which is conducive to the early rehabilitation and functional exercise, and the postoperative functional recovery of the knee joint is satisfactory.

Anti-CD19 chimeric antigen receptor (CAR)-T cell therapy has achieved 40%-50% long-term complete response in relapsed or refractory diffuse large B-cell lymphoma (DLBCL) patients. However, the underlying mechanism of alterations in the tumor microenvironments resulting in CAR-T cell therapy failure needs further investigation. A multi-center phase I/II trial of anti-CD19 CD28z CAR-T (FKC876, ChiCTR1800019661) was conducted. Among 22 evaluable DLBCL patients, seven achieved complete remission, 10 experienced partial remissions, while four had stable disease by day 29. Single-cell RNA sequencing results were obtained from core needle biopsy tumor samples collected from long-term complete remission and early-progressed patients, and compared at different stages of treatment. M2-subtype macrophages were significantly involved in both in vivo and in vitro anti-tumor functions of CAR-T cells, leading to CAR-T cell therapy failure and disease progression in DLBCL. Immunosuppressive tumor microenvironments persisted before CAR-T cell therapy, during both cell expansion and disease progression, which could not be altered by infiltrating CAR-T cells. Aberrant metabolism profile of M2-subtype macrophages and those of dysfunctional T cells also contributed to the immunosuppressive tumor microenvironments. Thus, our findings provided a clinical rationale for targeting tumor microenvironments and reprogramming immune cell metabolism as effective therapeutic strategies to prevent lymphoma relapse in future designs of CAR-T cell therapy.

Objective:To investigate the clinical effect of early bronchoalveolar lavage on patients with aspiration pneumonia.Methods:A retrospective study was conducted on 55 patients with aspiration pneumonia who met inclusion criteria but not exclusion criteria in the Intensive Care Department of our hospital from January 2020 to April 2021. The patients were divided into the control group (32 cases) and the bronchoscopic lavage group (23 cases) according to whether they received bronchoscopic lavage within 24 h after aspiration. Basic information (sex, age, body mass index, chest X-ray score, oxidation index, temperature, heart rate, respiratory rate, white blood cells, PCT, IL-6, CPR and APACHE Ⅱ score), etiology changes at the early stage (≤ 3 d) and later stage (4-7 d after admission), and changes in prognostic indexes (mechanical ventilation time, length of ICU stay, length of stay and mortality) were compared between the two groups. The clinical efficacy of early endoscopy lavage for aspiration pneumonia was evaluated.Results:The positive rate of early etiological culture was 85.2%, the bacterial positive rate was 72.9% and the fungal positive rate was 14.6%. Pseudomonas aeruginosa accounted for 20.8%, Klebsiella pneumoniae accounted for 14.6%, Staphylococcus aureus and Streptococcus accounted for 12.5%, and there was no significant difference in the distribution between the bronchoscopic lavage group and the control group (all P>0.05). The positive rate of late etiological culture was 88.6%, the bacterial positive rate was 85.7% and the fungal positive rate was 2.9%. The positive rate of late bacterial culture was significantly decreased in the bronchoscopic lavage group ( P < 0.05), and the other results were not significantly different from the control group (all P>0.05). After early bronchoscopic lavage, the duration of mechanical ventilation, length of ICU stay and length of stay were significantly shortened, and the fifth day CPIS score was significantly decreased (all P< 0.05). Conclusions:Early endotracheal lavage can reduce mechanical ventilation time, length of ICU stay and length of stay of aspiration pneumonia, and reduce the positive rate of bacterial culture in the lung at the later stage, which needs to be further verified by a large randomized controlled study.

Objective:To translate and revise the Quality of Life Questionnaire for Women with Gestational Diabetes Mellitus (GDMQ-36) , and test its reliability and validity.Methods:Brislin translation mode was used to translate the GDMQ-36 forward and back. Cultural adjustment and revision of the translated questionnaire were conducted through Delphi method and pre-survey method to form GDMQ-34. From January to May 2020, the questionnaire was used to conduct quality of life survey on 220 patients with gestational diabetes mellitus (GDM) in the Obstetrics Department of four ClassⅢ Grade A hospitals in Qingdao to evaluate its reliability and validity.Results:A total of 220 questionnaires were issued and 203 were effectively returned, with an effective recovery rate of 92.3%. The Chinese version of GDMQ-34 had 34 items, including 6 dimensions of pregnancy worry, behavioral restraint, physical symptoms, psychological symptoms, medications and social support. The total Cronbach's α coefficient of the Chinese version of GDMQ-34 was 0.772, and the test-retest reliability was 0.820, and the Cronbach's α coefficients of each dimension were 0.855, 0.902, 0.868, 0.880, 0.896 and 0.880 respectively. The content validity index at the average scale level of the questionnaire was 0.982, and the content validity index at the item level was from 0.867 to 1.000. The exploratory factor analysis extracted 7 common factors, and the cumulative variance contribution rate was 68.591%.Conclusions:The Chinese version of GDMQ-34 has good reliability and validity, and it is scientific and practical, and can be used as a simple tool for evaluating the quality of life of patients with GDM.

Objective:To explore the clinical effect of R-MAD (rituximab, methotrexate, cytarabine, dexamethasone) regimen in the treatment of primary ocular adnexal double-expression diffuse large B-cell lymphoma (DLBCL).Methods:The clinical data of an elderly patient with primary ocular adnexal double-expression DLBCL who was treated with R-MAD regimen in June 2019 in Fujian Medical University Union Hospital was retrospectively analyzed. The clinical manifestations, diagnosis and treatment, prognosis were also analyzed, and the related literature was reviewed.Results:The patients was a 71-year-old male. After initial treatment of R-CHOP chemotherapy, the patient's eye mass did not shrink, the swelling and pain became worse, the curative effect was not good, and the disease progression continued. After the patient was given R-MAD chemotherapy for 3 courses, the eye swelling subsided and pain symptoms were significantly improved, satisfactory results were obtained, and no obvious adverse reactions occurred.Conclusions:R-MAD regimen has an ideal effect on the patient with primary ocular adnexal double-expression DLBCL, which can significantly improve symptoms, delay disease progression, and improve the quality of life of patients, but the prognosis still needs to be followed up in the long-term.

Objective:To investigate the orthopedists' cognition on Chinese Osteoarthritis Guideline (2018 Edition).Methods:Questionnaire about Chinese Osteoarthritis Guideline (2018 Edition) was developed and sent to orthopedists via an invitation link to fill out after authorization from Chinese Osteoarthritis Association. The content of the questionnaire included the basic personal information of the physician, the awareness rate of the guidelines, the evaluation of the guidelines, and its application effects. The survey duration was from September 2019 to December 2019. Multivariate logistic regression and linear regression analysis were performed for the guideline awareness rate and comprehensive score, respectively.Results:A total of 628 physicians completed the questionnaire, of which 623 of 628 (99.2%) were available. About 72.4% of the orthopedists knew the guideline. The awareness rate was statistically related to the education of the physicians ( P<0.05). Respondents' overall score for the guideline was 8.39 with methodological score 8.28. A total of 41.2% of orthopedists thought that the guideline was very good compared with the European and American guidelines, and the clinical problem coverage rate was 78.6%. There is a statistically significant difference in the appraisal of the recommendations ( χ2=138.9, P<0.05) . More than 40% of orthopedists believed that the guidelines were of great help to orthopedists and patients, and that the guide could be promoted to the primary hospitals. Conclusion:After one year publication of Chinese Osteoarthritis Guideline (2018 Edition), most orthopedists have understood the present guideline and applied recommendations in clinical practice. However, the guideline need to be further promoted and disseminated in the future.
