Objective To investigate the value of enhanced CT radiomics combined with CT features model(combined model)for differentiating squamous cell carcinoma(SNSCC)and sinonasal lymphoma(SL).Methods Totally 68 patients with SNSCC and 63 patients with SL were retrospectively collected and divided into training set(n=92,including 48 SNSCC and 44 SL)and verification set(n=39,including 20 SNSCC and 19 SL)at the ratio of 7:3.Univariate analysis and logistic regression were used to analyze clinical data and CT manifestations in training set,and the independent predictive factors for differentiating SNSCC and SL were screened and used to construct a CT features model.Based on enhanced venous phase CT of training set,the best radiomics features of lesions were extracted and screened.The radiomics model was then established,and the radiomics label was calculated.The combined model was finally constructed based on CT model and radiomics labels,and its nomogram was drawn.Receiver operating characteristic(ROC)curve were drawn,and the areas under the curve(AUC)were calculated to evaluate the efficacy of each model for differentiating SNSCC and SL.Calibration and decision curve analysis were used to evaluate the calibration efficacy and clinical benefit of the obtained combined model.Results The primary location of the lesion and bone invasion showed on CT were both independent predictive factors for SNSCC and SL(both P＜0.05),and CT model was constructed.Based on enhanced venous phase CT,3 best radiomics features were selected to establish the radiomics model.The AUC of CT,radiomics and combined model in training set was 0.895,0.730 and 0.925,respectively,and significant differences of AUC were found among 3 models(Z=-3.964 to-1.833,all P＜0.05).The AUC of CT,radiomics and combined model in verification set was 0.845,0.684 and 0.868,respectively,of combined model was greater than of radiomics model(Z=-2.568,P=0.010).The combined model had good calibration.Taken 15％-62％ and 85％-92％ as the thresholds in training set and 88％ to 95％ in validation set,the clinical net benefit of combined model was high.Conclusion The obtained enhanced CT radiomics combined with CT features model could be used to effectively differentiate SNSCC and SL.

Objective: By implementing the best practice of bedtime and position after diagnostic adult lumbar puncture,we hope to establish a scientific and standardized nursing routine for lumbar puncture, shorten the bed-rest time after lumbar puncture, and improve the comfort of patients. Methods: By reviewing literatures related to positions after adult lumbar puncture and post-dural puncture headache, six best practice were concluded. By combining the best evidence and the clinical circumstances, the evidenced-based criteria were established and then applied in the Neurology Department. Results: After two rounds of reviews, the results showed that except the 93.3% compliance with the new evidence, all other four criteria had 100% complacence. Comparing before and after applying the evidence, there was no statistically significant difference for the occurrence of post-dural puncture headache or dizziness(P>0.05), there was a statistically significant reduction of back pain from 28.3%(30/106) to 15.1%(18/119)(χ² value was 5.799, P<0.05) when the evidence was applied. Conclusions The best practice shows that patients needn′t lie on bed for 4 to 6 hours after lumbar puncture, the occurrence of back pain is lowered and the comfort level of the patient is improved in those who rest with pillow or activities.

Objective:To construct the intelligent medical cloud management platform of diabetes education clinic in ClassⅢ general hospital and observe the clinical effects.Methods:A total of 260 young and middle-aged patients with type 2 diabetes mellitus (T2DM) who were admitted to Department of Endocrinology in the First Affiliated Hospital of Henan University from June to December 2019 were selected by convenience sampling method. They were divided into the control group and the experimental group by the random number table method, with 130 cases in each group. Patients in the control group were given routine diabetes outpatient follow-up, while the experimental group was given group education, case management, behavioral intervention, condition supervision and online follow-up intervention based on the intelligent medical cloud management platform of the diabetes education clinic. The blood glucose control status and the self-management ability of the two groups before and after 3 months of intervention were compared.Results:After intervention for 3 months, fasting plasma glucose (FPG) , 2h plasma glucose of 75g oral glucose tolerance test (OGTT 2h PG) and hemoglobin A1c (HbA1c) of patients in two groups were reduced than those before intervention, and FPG, OGTT 2h PG and HbA1c levels in the experimental group were lower than those in the control group. The differences were statistically significant ( P<0.05) . The mean blood glucose (MBG) and mean amplitude of plasma glucose excursions (MAGE) in the experimental group were lower than those in the control group, and the difference was statistically significant ( P<0.05) . After 3 months of intervention, blood glucose was monitored 6 833 times in the control group and 7 279 times in the experimental group. The incidence of hypoglycemia in the experimental group was lower than that in the control group [0.77% (56/7 279) vs. 2.82% (193/6 833) , χ 2=85.885, P<0.05]. After 3 months of intervention, the scores of diet, exercise, blood glucose monitoring, prevention of complications and medical compliance in the two groups were all higher than those before intervention, and the scores of diet, exercise, blood glucose monitoring and medical compliance in the experimental group were higher than those in the control group. The differences were statistically significant ( P<0.01) . Conclusions:The construction and application of intelligent medical cloud management platform of diabetes education clinic can better improve blood glucose control and improve self-management ability of patients.

" Day surgery hospital-community joint follow-up model " results newly from the deepening implementation of the hierarchical medical system policy. It is designed to follow up the patients discharged from hospital but not fully recovered in time to ensure the prevention of adverse events after surgery. It can also improve the quality and efficiency of follow-up, and ensure the safety and integrity of the whole day operation management. In this context, through a comparative study of 720 patients discharged from daytime surgery in the region, patients in the combined follow-up group were followed up by telephone on the 3rd day after the operation by nurses from the day surgery ward. On the 10th and 20th days after the operation, the family doctor from the community health service center will visit the patient at home and follow up the patient by telephone. One month later, the patient returned to the hospital for follow-up consultation. Follow-up results show day surgery hospital-community joint mode as a helpful aid in keeping track of the patients postoperative rehabilitation, reducing complications and handling in time, while improving the ambulatory surgery perioperative safety.

Femoroacetabular impingement (FAI) is a common cause of hip pain and limited range of motion among young and middle-aged active adults and athletes. The acetabular labral tear and cartilage damage secondary to FAI may increase the risk of hip osteoarthritis. FAI is characterized by pathologic impact between the femoral headneck junction and the acetabular rim secondary to bony deformity. According to the pathological anatomy leading to impingement, the FAI can be divided into the femoral cam-type deformity (Cam), the acetabular over-coverage deformity (Pincer) and a combination of both. In recent years, arthroscopic osteoplasty of the femoral head-neck junction is the main way to treat the Cam deformity; However, there still remain some controversies about how to perform an adequate and effective arthroscopic femoroplasty. Based on this problem, the present article reviewed the preoperative diagnosis, intraoperative evaluation, surgical techniques and postoperative evaluation of Cam-type FAI to explore how to adequately correct Cam deformity under arthroscopy. In the present study, a total of 1928 related articles were obtained by searching PubMed, Web of Science, Cochrane library, China Knowledge Network, Wanfang Full-text Database and Weipu Science and Technology Journal Database. According to the inclusion and exclusion criteria, 43 papers were finally included. After summarizing the above literatures, it was found that anatomical structures such as Cam deformity, femoral neck anteversion, and acetabular coverage can be evaluated preoperatively by X-ray, three-dimensional CT and MRI. X-ray fluoroscopy and arthroscopic dynamic examination are performed during the femoroplasty to locate the Cam deformity and to determine whether the femoral neck offset radio and the spherical structure of femoral head are corrected, at the same time, it is necessary to consider the overall anatomy of the hip joint to achieve an adequate resection of the Cam deformity and restore the normal mobility of the hip joint.

Objective To assess the bone tunnel area at different times and sites of the tunnel after the anterior cruciate ligament(ACL) reconstruction in rabbits using Micro-CT.Methods Fifteen rabbits were performed ACL reconstruction using semitendinosus tendon autograft and randomly allocated into 3 groups and killed at 3,6,and 12 weeks after the operation.All samples undertook the micro-CT scanning(using SkyScan 1176,Bruker,U.S.A.) and were analyzed the areas of bone tunnels of femur and tibia after the 3-demension image rebuilding.For each tunnel,the area of the entrance,middle and exit of the tunnel were measured 3 times respectively and compared.Results The average area of the femoral tunnel did not change significantly with time,being 4.84 mm2,4.57 mm2 and 4.46 mm2 at 3,6 and 12 weeks after the operation(P=0.99).At the very beginning,the femoral tunnel area at the entrance was the biggest,while that of the middle was the smallest.Six weeks after the operation,significant differences were observed between the femoral tunnel area at the entrance and middle,as well as that between the exit and middle(P=0.0011,P=0.0106);However,12 weeks after the operation,significant differences were observed only between that at the entrance and middle(P=0.0227).The average tibial tunnel area increased significantly at 6 weeks(6.577 mm2) and decreased at 12 weeks(3.103 mm2) after the operation(P=0.0005).Moreover,no significant differences were observed in the average tibial tunnel area at different time points and sites(P＜0.05).At different sites,the average tibial tunnel area expanded at 6 weeks,and then declined at 12 weeks after the operation.Conclusion The bone tunnel area changes with time after the ACL reconstruction,first increasing followed by decreasing in the average tibial tunnel area.The femur and tibial tunnel have significant differences in the tunnel area at different sites,which change differently with time.The bone tunnel expansion after the anterior cruciate ligament reconstruction can be comprehensively measured repeatedly at different sites.

Objective To investigate the effect of arthroscopy-assisted latissimus dorsi transfer (LDT) on posterosuperior massive rotator cuff tear (psMRCT) and analyze factors related to the outcome.Methods A retrospective case cohort study was conducted to analyze 31 patients with psMRCT admitted from January 2013 to December 2015.There were 13 males and 18 females,aged 52-67 years [(58.4 ± 4.5) years].The mean duration of symptoms was (1.9 ± 0.9) years.All patients received arthroscopy assisted LDT combined with rotator cuff repair.Postoperative rehabilitation training was carried out according to the standard procedures.Before operation and at the last follow-up,X-ray films were taken to measure the acromiohumeral talus,and magnetic resonance imaging was obtained to check the integrity of repaired tissue.Visual analog scale (VAS),active range of motions,Constant-Murley score and Fudan University Shoulder Score (FUSS) were measured to assess the shoulder joint function,and complications were documented.Furthermore,subgroup analysis was made according to "concomitant subscapularis tendon tear or not","concomitant pseudoparalysis or not","Goutallier Ⅲ/Ⅳ level fatty infiltration","complete or partial rotator cuff repair",and " Hamada Ⅰ/Ⅱ level acromiohumeral distance".Pearson correlation analysis was performed to detect the relationship of subgroup factors with postoperative Constant-Murley score and FUSS score.Results All patients were followed up for (38.8 ± 13.0) months.No complications including fever,infection,adhesion or neural malfunction were reported.Mean acromiohumeral distance increased from preoperative (5.4 ± 0.9) mm to (7.0 ± 1.0) mm at the last follow-up (P ＜ 0.05).MRI image showed intact fixation of rotator cuff and transferred latissimus dorsi tendon.At the last follow-up,VAS score decreased from preoperative (4.8 ± 1.4)points to (0.6 ± 0.7)points;the active range of motions was restored significantly;the Constant-Murley score improved from (32.9 ± 9.5) points to (67.4 t 6.7) points;the FUSS score increased from (53.3 ± 9.1) points to (85.1 ± 4.8) points (all P ＜ 0.01).Pearson Correlation analysis indicated that,among subgroup factors,only partial rotator cuff repair was significantly inversely associated with ConstantMurley score (P ＜ 0.05) and FUSS score (P ＜0.01),and the Constant-Murley score and FUSS score of patients with complete repair were significantly higher than those of patients with partial repair (P ＜ 0.05 and P ＜ 0.01,respectively).Conclusions For psMRCT,the effect of arthroscopy-assisted LDT is confirmed,which can relieve pain,restore range of motion and improve shoulder function.Preoperative pseudoparalysis,subacapularis tendon tear,Goutallier Ⅳ level fatty infiltration and Hmada Ⅱ level acromiohumeral distance do not significantly influence postoperative outcome.The torn rotator cuff tear should be repaired as possible.
