Recent advances on clinical treatment of congenital pseudarthrosis of the tibia WU Chunxing, NING Bo 2024, 13 (3):  181-185.  doi: 10.3969/j.issn.2095-378X.2024.03.001 Abstract ( 46 )   PDF (579KB) ( 50 )   Save Congenital pseudarthrosis of the tibia（CPT） is a rare tibia disease in children's orthopedics, which is prone to bone nonunion, pseudarthrosis, and lower limb deformity, and is difficult to cure. Successful treatment remains challenging for orthopedic surgeons, despite many treatments developed for this disease. In recent years, with the in-depth study of CPT, the invention of new surgical methods such as "4-in-1 fusion" and "Cross-union" of tibia and fibula, and the comprehensive use of new drugs such as bisphosphonates and bone morphogenetic proteins, the cure rate has gradually increased and the rate of refracture has reduced. The present status and progress of treatment of CPT in recent years were summarized in this paper, aiming to provide reference for clinical treatment. References | Related Articles | Metrics

Application of radiomics nomogram in predicting risk of cardiovascular diseases in patients with diabetic kidney disease LI Le, WANG Shuo, PANG Yanping, WANG Xiuyan 2024, 13 (3):  186-191.  doi: 10.3969/j.issn.2095-378X.2024.03.002 Abstract ( 69 )   PDF (3193KB) ( 49 )   Save Objective To establish and validate a nomogram model based on multimodal ultrasound radiomics to predict the risk of cardiovascular diseases （CVD） in patients with diabetic kidney disease （DKD）. Methods A retrospective analysis of baseline clinical data and multimodal ultrasound images from 167 DKD patients was conducted. The ultrasound images were segmented and radiomic features were extracted using 3D Slicer software. A radiomics score was generated for each patient using the least absolute shrinkage and selection operator （LASSO） algorithm. Based on these scores and clinical predictors related to CVD, a nomogram model was established to predict the risk of CVD in DKD patients. The model was internally validated using the receiver operating characteristic （ROC） curve, calibration curve, and decision curve analysis （DCA）. Results Utilizing the LASSO algorithm, five radiomic features closely related to the incidence of CVD were extracted from the dual mode elastography of each patient. The radiomics score, which was constructed based on these features, predicted the risk of CVD with an area under ROC curve （AUC） of 0.764. In terms of clinical features, age, body mass index, low-density lipoprotein cholesterol, and glycated hemoglobin were identified as independent risk factors for developing CVD. A radiomics nomogram, built based on these factors and the radiomics score, significantly outperformed the radiomics score alone in predicting the risk of CVD, with an AUC of 0.897. The calibration curve demonstrated a high consistency between the predicted probability of CVD occurrence by the nomogram and the actual incidence. DCA further validated that the nomogram achieved a net clinical benefit at different threshold probabilities. Conclusion The radiomics nomogram established in this study demonstrates excellent performance in predicting the risk of DKD patients developing CVD. It holds promise to aid clinicians in achieving individualized management and early intervention for DKD patients. References | Related Articles | Metrics

Clinicopathological features of clear cell papillary renal cell tumour： Report of four cases WU Yunjin, LI Jie, ZHANG Tingting, FAN Desheng 2024, 13 (3):  192-196.  doi: 10.3969/j.issn.2095-378X.2024.03.003 Abstract ( 59 )   PDF (3099KB) ( 46 )   Save Objective To investigate the clinical and pathological characteristics, diagnosis, and differential diagnosis of clear cell papillary renal cell tumour （CCPRCT）, aiming to enhance the understanding of this tumour. Methods Clinical data, histopathological patterns, immunohistochemical and molecular assay results of four patients with CCPRCT were retrospectively analysed, followed up and reviewed in the literature. Results The study included four patients, two males and two females, aged between 39 and 73 years. One of the patients had a history of end-stage renal disease. The masses observed had a maximum diameter ranging from 1 to 3.5 cm, were well-defined, either solid or cystic, and had a color ranging from grayish-white to grayish-yellow and grayish-red. Under the light microscope, the tumour cells were arranged in tubular, papillary, vesicular or cystic shapes with varying proportions. The tumour cells were small and cubic with transparent cytoplasm. The World Health Organization/International Society of Urological Pathology （WHO/ISUP） nuclear grading was 1-2 for the tumour cells, and the characteristic nuclei were neatly arranged at the lumen edge away from the basement membrane. There was no renal sinus invasion, vascular invasion, coagulation necrosis, or other aggressive tumour features. The immunophenotypes of the tumour cells were positive for cytokeratin （CK）7, carbonic anhydrase （CA）Ⅸ, pan-cytokeratin （panCK） AE1/AE3 and vimentin, partially positive for CD10, and negative for P504S, CD117 and TFE3. The fluorescence in situ hybridization did not show any 3p deletion. Follow-up was conducted on three cases for 8-78 months, and none of them experienced tumour recurrence or metastasis. Conclusion CCPRCT is a rare renal tumour with a good clinical prognosis. It is important to differentiate it from common low-grade clear cell renal cell carcinoma and papillary renal cell carcinoma. Accurate diagnosis can improve the quality of patients' survival. References | Related Articles | Metrics

Methods A total of 86 patients with inverted papilloma of nasal cavity and paranasal sinuses admitted from January 2019 to August 2022 were randomly divided into an observation group and a control group according to random number method, with 43 cases in each group. The observation group received treatment via the endoscopically assisted approach targeting the anterior lacrimal recess, while the control group was treated with endoscopically assisted Caldwell-Luc approach. The sinus function scores, surgery-related indicators,objective inspection indexes, and 1-year recurrence rate were compared between the two groups. Results Six months post-operation, the observation group showed significant improvements in nasal symptoms, sleep disturbances, emotional well-being, and symptom scores, surpassing those in the control group （P<0.05）. Surgical duration, blood loss during surgery, and lengths of hospital stays were also notably reduced in the observation group compared to the control group （P<0.05）. The scores of objective evaluations of conditions such as polyps, mucosal swelling, and nasal discharge in the observation group were significantly lower than those in the control group （P<0.05）. Furthermore, the rates of complications like nasolacrimal duct damage, channel adhesion, numbness around the wound, and narrowing of the wound were significantly lower in the observation group than in the control group （P<0.05）. Although the 1-year recurrence rate in the observation group was lower than that in the control group, this difference did not reach statistical significance （P>0.05）. Conclusion Endoscopy-assisted anterior lacrimal recess approach for the treatment of inverted papilloma of nasal cavity and paranasal sinuses has more significant advantages in improving sinus function, and reducing operation-related indicators, objective examination indicators and complications than the Caldwell-Luc approach.

Methods A total of 86 patients with cN0 stage unilateral papillary thyroid carcinoma who underwent surgical treatment from January 2020 to June 2023 were randomly divided into a control group and an observation group, with 43 patients in each group. The control group underwent endoscopic thyroidectomy via the oral vestibular approach, while the observation group underwent endoscopic thyroidectomy via the axillary approach. The surgical time, intraoperative blood loss volume, postoperative drainage volume, number of central lymph node dissections, visual analog scale （VAS） score, total incidence of complications, and postoperative satisfaction were observed and compared between the two groups of patients. Results The intraoperative blood loss volume, postoperative drainage volume, and VAS score of the observation group were all lower than those of the control group （P<0.05）, but the number of central lymph node dissection was higher （P<0.05）. There was no statistically significant difference in surgical time and hospitalization time between the two groups of patients （P>0.05）. There was also no statistically significant difference in the total incidence of complications between the observation group （16.27%） and the control group （18.60%） （P>0.05）, but the postoperative satisfaction rate （97.67%） of the observation group was higher than that of the control group （79.07%）, and the difference was statistically significant （P<0.05）. Conclusion Transaxillary endoscopic thyroidectomy can better protect the anterior cervical functional area and reduce postoperative discomfort in the anterior neck. Comparably, transoral vestibular endoscopic thyroidectomy features smaller operating space, higher difficulty, overall longer surgical time, and higher risks of postoperative infection, despite better cosmetic effect. Therefore, transaxillary endoscopic thyroidectomy is more effective in the treatment of cN0 unilateral papillary thyroid carcinoma. References | Related Articles | Metrics

During the hospital stay, the physical indexes of the two groups of preterm infants were observed and recorded every day, the neonatal growth and development indexes of the two groups before discharge were recorded, and two independent samples were analyzed by t-test. Results The general data of preterm infants in the two groups were balanced at baseline, the weight and body length of preterm infants in the intervention group were higher than those in the control group after the implementation of family-integrated care （P<0.05）, and the head circumference of the intervention group was higher than that of the control group, but the difference was not statistically significant （P>0.05）. Conclusion The educational content of neonatal care should be homogeneous. Standardized family-integrated care promotes the growth and development of premature infants, which is worthy of clinical application. References | Related Articles | Metrics

Application of “three fixed” emergency mode in emergency rescue of patients with ectopic pregnancy and massive bleeding LI Yina, WU Binbin, LIN Jinshi, HUANG Guoliang 2024, 13 (3):  265-268.  doi: 10.3969/j.issn.2095-378X.2024.03.019 Abstract ( 47 )   PDF (636KB) ( 19 )   Save Objective To study the application effect of "three fixed" emergency mode in emergency rescue of patients with ectopic pregnancy and massive bleeding. Methods A total of 87 patients with ectopic pregnancy and massive bleeding admitted from January 2021 to May 2023 were selected and divided into a routine group （n=45） and a three fixed group （n=42）. The routine group received routine emergency nursing, while the three fixed group received “three fixed”emergency nursing.The evaluation indicators of emergency response timeliness, shock index, emergency nursing satisfaction of the two groups of patients were recorded, and the stress level of nurses before and after intervention, satisfaction of rescue medics, and skill scores of nursing staff were compared. Results The rescue time and total rescue and nursing time of the three fixed group were shorter than those of the routine group, and the total bleeding volume was lower （P<0.05）. The shock index of the three fixed group after intervention was significantly better than that of the routine group （P<0.05）. The nursing satisfaction of patients in the three fixed group was 97.62%, which was higher than 82.22% in the routine group （P<0.05）. The stress score of nurses in the routine group was higher than that in the three fixed group, while the satisfaction score of rescue medics was lower （P<0.05）. The basic abilities, professional first aid skills, and other skills of the nursing staff in the three fixed groups were significantly improved compared to the routine group（P<0.05）. Conclusion The implementation of the“three fixed” emergency mode for patients with ectopic pregnancy and massive bleeding can help improve the efficiency of medical staff's emergency response, relieve shock of patients, reduce the pressure of nursing staff on emergency response, and increase the satisfaction of patients and rescue medics, which is worthy of promotion.

Malakoplakia of the vaginal stump： A case report WANG Zhiyu, XU Han, OUYANG Yiqin 2024, 13 (3):  269-272.  doi: 10.3969/j.issn.2095-378X.2024.03.020 Abstract ( 38 )   PDF (6254KB) ( 44 )   Save Malakoplakia is a rare, curable, and self-limited chronic granulomatous inflammatory disease. The diagnosis of malakoplakia depends on histopathological examination. Malakoplakia can be treated with strong antibiotics or antibiocits combined with surgery. Case reports of malakoplakia are rarely seen in China at present. It occurs more often in the genitourinary system, and hardly in the vaginal stump. Here we reported the diagnosis and conservative treatment of an elderly female case of vaginal stump malakoplakia, aiming to raise the understanding of the disease.
