Analysis of learning curve of mouse neck heart allograft model WANG Hui, LIU Yiwei, LIU Yuan, YANG Pengjie, LIANG Yue 2024, 13 (1):  7-12.  doi: 10.3969/j.issn.2095-378X.2024.01.002 Abstract ( 111 )   PDF (2079KB) ( 161 )   Save Objective To investigate the learning curve of mouse cervical heart allograft model. Methods A retrospective analysis was conducted of 60 cases of mouse cervical heart allograft. The total transplantation time, recipient preparation time, donor preparation time, arteriovenous cannulation time, and donor cardiovascular connection time were recorded during the operation. Cumulative sum （CUSUM） analysis method and the best fitting curve were used to obtain the minimum number of animals required to pass the learning period in the learning curve of each surgery stage. The mice were divided into a learning stage group and a mature stage group with the minimum number of cases for the surgery stage with the longest learning curve as cut-off point, and the differences in operation time and failure rate were compared between the two groups. Results Sixty mice completed neck heart allograft. The total transplantation time was （119.80±43.17） min, the recipient preparation time was （76.43±26.46） min, the donor preparation time was （29.85±9.82） min, the arteriovenous cannulation time was （32.10±21.62） min, and the donor cardiovascular connection time was （17.47±8.43） min. A cubic CUSUM learning curve was best fit to the data. The minimum number of surgical cases corresponding to the learning curve of each surgery stage was 25 cases for recipient surgery, 19 cases for donor surgery, 29 cases for arteriovenous cannulation, 24 cases for donor cardiovascular connection, and 25 cases for the whole operation. Taking the 29 cases for the surgery stage with the longest learning curve （arteriovenous cannulation） as cut-off point, compared with the learning stage group, the total transplantation time [（156.80±32.80） min vs. （85.06±9.45） min], recipient preparation time [（95.41±18.89） min vs. （50.94±7.45） min], donor preparation time [（37.03±9.51） min vs. （23.13±2.95） min], arteriovenous cannulation time [（50.41±16.65） min vs. （14.97±5.74） min], and donor cardiovascular connection time [（24.38±7.16） min vs. （11.00±1.55） min] were significantly reduced in the mature stage group （P<0.01）. The surgical failure rate of the mature stage group was significantly lower than that of the learning stage group （48.28% vs. 9.68%, P=0.0013）. Conclusion The learning curve of the cervical heart allograft model is slightly different in each operation stage, and the surgical technique is basically mature when the sample number reaches 29 cases. After the surgical technique is mature, the operation time and the mature success rate will be significantly improved. References | Related Articles | Metrics

Methods Sixty patients with spinal tuberculosis who received surgical treatment in our hospital from January 2021 to December 2022 were selected as the observation group, and 60 patients without spinal tuberculosis who underwent spinal surgery were selected as the control group （Some cases were from partner hospitals in the Fund）. The expression levels of TLR-4, TNF-α, IL-6, and IL-17 in serum and lesion tissues of the two groups were detected. According to the prognosis 6 months after operation, patients in the observation group were divided into a good prognosis group and a poor prognosis group. Serum expression levels of TLR-4, TNF-α, IL-6, and IL-17 were compared between the two groups before and 6 months after operation. Pearson correlation was used to analyze the relationships between the expression levels of serum TLR-4, TNF-α, IL-6, and IL-17 before surgery and the score of modified Babbitt index （MBI） 6 months after surgery in patients with spinal tuberculosis. Receiver operating characteristic （ROC） curve was used to analyze the predictive efficacy of serum TLR-4, TNF-α, and IL-6 combined with IL-17 for postoperative poor prognosis of spinal tuberculosis. Results The expression levels of TLR-4, TNF-α, IL-6, and IL-17 in serum and lesion tissues of the observation group were higher than those of the control group before operation, with significant differences （P<0.05）. The levels of TLR-4, TNF-α, IL-6, and IL-17 in the poor prognosis group were higher than those in the good prognosis group,with significant differences （P<0.05）. Six months after surgery, the expression levels of TLR-4, TNF-α, IL-6, and IL-17 in serum of the good prognosis group were significantly lower than those before surgery, and the differences were statistically significant compared with those of the poor prognosis group （P<0.05）. By Pearson correlation analysis, the expression levels of serum TLR-4,TNF-α, IL-6, and IL-17 in patients with spinal tuberculosis before surgery were negatively correlated with MBI scale score 6 months after surgery （P<0.05）. According to ROC curve analysis, the area under curve of preoperative serum TLR-4, TNF-α, and IL-6 combined with IL-17 for predicting poor prognosis after spinal tuberculosis surgery was 0.921. Conclusion Serum TLR-4, TNF-α, IL-6, and IL-17 after spinal tuberculosis surgery are significantly lower than those before surgery, which is closely related to prognosis. Preoperative serum TLR-4, TNF-α, and IL-6 combined with IL-17 can predict poor prognosis effectively, which is worthy of clinical attention. References | Related Articles | Metrics

Methods A total of 76 patients with traumatic multiple rib fractures from July 2020 to January 2023 were selected as study subjects and divided into two groups, 38 cases in each group. The control group was treated with external fixation with chest guard plate, and the observation group was treated with internal fixation with preformed rib locking titanium plate. The clinical efficacy, the first out-of-bed time, visual analogue scale （VAS） score at 7 d postoperatively, mechanical ventilation time, hospitalization time, and fracture healing time were compared between the two groups. The forced expiratory volume in the first second （FEV1）, forced vital capacity （FVC）, and ratio of forced expiratory volume in the first second to forced vital capacity （FEV1/FVC） were detected with a pulmonary function measuring device at 7 d and 3 months after operation, respectively. The incidence of postoperative complications was also compared. Results Compared to the control group, the excellent and good rate of the observation group was significantly higher （P<0.05）; the first out-of-bed time, VAS score at 7 d postoperatively, mechanical ventilation time, hospitalization time, and fracture healing time in the observation group were significantly shorter （P<0.05）. There was no significant difference in FEV1, FVC, and FEV1/FVC between the two groups 7 d after operation （P>0.05）. FEV1, FVC, and FEV1/FVC in the two groups increased 3 months after operation, and the observation group showed higher levels than the control group （P<0.05）. The incidence of postoperative complications in the observation group was significantly lower than that in the control group （P<0.05）. Conclusion For patients with traumatic multiple rib fractures, the effect of internal fixation with preformed rib locking titanium plate is better than that of external fixation with chest guard plate, which can promote the early recovery of patients, improve long-term lung function, and reduce the incidence of postoperative complications.

Invasive stratified mucin-producing carcinoma： Clinicopathological analysis of three cases and literature review CHEN Xue, ZENG Yu, BI Xiaohan, ZHANG Suxia 2024, 13 (1):  39-43.  doi: 10.3969/j.issn.2095-378X.2024.01.009 Abstract ( 95 )   PDF (12411KB) ( 155 )   Save Objective To conduct a case study on invasive stratified mucin-producing carcinoma （ISMC）, a newly named human papillomavirus （HPV）-related cervical mucinous adenocarcinoma, and provide clinical and pathological data for this rare disease. Methods Three cases of ISMC were retrospectively analyzed, and the pathological characteristics, immunophenotype, HPV genotyping, and prognosis were explored in combination with relevant literature. Results ISMC tumor cells exhibited a diversity of structural patterns and cell morphology. The cytoplasm of the tumor cells contained different amounts of mucus, and neutrophil infiltration could be seen around the nests and intratumorally. Apoptotic bodies and mitosis were found in all three cases. Immunohistochemistry showed p16 and CK7 were diffuse and strong （+）, while PAX8, p40, and CK5/6 were slight （+） around the nests . Conclusion ISMC is a rare, HPV-associated adenocarcinoma with a broad morphological spectrum. The unique expression patterns of PAX8, CK5/6, and p40 can be used as effective markers for ISMC diagnosis. ISMC has a poor prognosis, and it is important that even if a small amount of ISMC components are detected, their percentages should be noted in the diagnosis.

Influences of multidimensional support intervention based on ERAS on postoperative training compliance, pain, and joint function rehabilitation in patients with calcaneal fractures ZHAO Haiyan, LI Xia 2024, 13 (1):  80-82.  doi: 10.3969/j.issn.2095-378X.2024.01.020 Abstract ( 99 )   PDF (1250KB) ( 335 )   Save Objective To observe the effects of multidimensional support intervention based on the concept of enhanced recovery after surgery （ERAS） on recovery of patients after calcaneal fracture surgery. Methods A total of 53 patients with calcaneal fractures who underwent surgical treatment from February 2022 to September 2023 were included in the study. They were randomly divided into a control group （n=26, conventional nursing intervention） and an observation group （n=27, multidimensional support intervention based on the concept of ERAS） by random number table method. The compliance with training, pain level （verbal rating scale, VRS）, and joint function [American Orthopaedic Foot & Ankle Society （AOFAS） ankle-posterior foot score] were compared between the two groups before and after intervention. Results After intervention, the compliance score and AOFAS ankle-posterior foot score in the observation group were higher than those in the control group, while the VRS score was lower （P<0.05）. Conclusion Multidimensional support intervention based on the REAS concept can improve the compliance of patients with calcaneal fractures in postoperative training, effectively alleviate postoperative pain, and have positive effects on promoting joint function rehabilitation.

Effects of diversified nursing on functional rehabilitation and quality of life of patients with hand and foot trauma undergoing vacuum sealing drainage JIN Lichen, ZHANG Ying, YANG Haojun 2024, 13 (1):  83-86.  doi: 10.3969/j.issn.2095-378X.2024.01.021 Abstract ( 58 )   PDF (1373KB) ( 210 )   Save Objective To investigate the effects of diversified nursing on functional rehabilitation and quality of life in patients with hand-foot trauma who underwent vacuum sealing drainage （VSD）. Methods A total of 112 patients with hand and foot trauma treated with VSD in our hospital from June 2022 to April 2023 were selected and divided into an observation group （56 cases） and a control group （56 cases） by random number table method. Patients in the control group received routine nursing intervention, while patients in the observation group received diversified nursing intervention. The functional recovery, quality of life scores （emotion index, life satisfaction index, and health index）, and complications （such as infection, joint stiffness, and folliculitis） were compared between the two groups. Results After intervention, 31 patients in the observation group had excellent functional recovery, 23 cases were good, and 2 cases were poor. The excellent and good rate was 96.4% in the observation group, which was higher than 78.6% in the control group （P<0.05）. There was no difference in the health index, emotion index, and life satisfaction index between the two groups of patients before intervention （P>0.05）, but after intervention, the scores of all indicators in the observation group were higher than those in the control group （P<0.05）. In terms of complications, only 1 case of infection and 1 case of joint stiffness occurred in the observation group, with a complication rate of 3.6%, which was significantly lower than that of 30.4% in the control group （P<0.05）. Conclusion The use of diversified nursing for the intervention of patients with hand and foot trauma after VSD is helpful to promote the functional rehabilitation, reduce the occurrence of complications, and improve the quality of life.
