Objective To analyze the predictive value of preoperative magnetic resonance imaging(MRI)indexes in patients with full thickness rotator cuff tear(FTRCT)undergoing arthroscopic rotator cuff repair(ARCR).Methods Clinical data of 451 patients with FTRCT undergoing ARCR from January 2020 to December 2023 were retrospectively included as the study objects.All patients were followed up for 1 year after surgery.Patients were divided into the shoulder joint function improvement group(n=415)and the shoulder joint function non-improvement group(n=36)according to scores of disabilities of the arm shoulder and hand(DASH).The preoperative MRI indicators and clinical indicators of the two groups were compared,and the risk factors of the outcome after ARCR in patients with FTRCT were analyzed by multivariate Logistic regression,and the receiver operating characteristic curve(ROC curve)was drawn.The predictive value of preoperative MRI indexes alone and in combination in patients with FTRCT undergoing ARCR was analyzed.Results 451 patients with FTRCT after ARCR were followed up for 1 year.The incidence of shoulder joint function non-improvement was 7.98％.Compared with the shoulder joint function improvement group,the shoulder joint function non-improvement group had longer preoperative tendon tear width and tendon retraction distance,higher degree of tendon degeneration,and shorter acromial humeral space(P＜0.05).Acromial humeral space ≤7.15 mm(OR=2.208,95％CI:1.255～3.883),tendon degeneration degree 2-3(OR=1.817,95％CI:1.066～3.096),tendon tear width＞2.16 cm(OR=2.246,95％CI:1.242～4.059)and tendon retraction distance＞2.10 cm(OR=2.186,95％CI:1.311～3.646)were risk factors for non-improvement of the shoulder joint in patients with FTRCT after ARCR(P＜0.05).Positive as shoulder joint function nonimprovement was included and negative as shoulder joint function improvement,ROC was drawn,and the predictive value of preoperative MRI indexes detection alone and combined in patients with FTRCT after ARCR was analyzed.The area under the curve(AUC)was 0.903,the sensitivity was 86.11％,and the specificity was 87.47％.Conclusion Patients with FTRCT who underwent ARCR surgery have better outcomes.Tendon tear width＞2.16 cm,tendon retraction distance＞2.10 cm,tendon degeneration degree of grade 2 to 3,acromial humeral space ≤7.15 mm are risk factors for poor outcomes,and the combined detection of preoperative MRI indexes has high predictive value.

Objective:To investigate the relationship between preoperative plasma fibrin degradation products (FDP) level and clinicopathological features of patients with completely resected non-small cell lung cancer (NSCLC).Methods:A retrospective case series study was performed. The clinical data of 521 patients who were pathologically diagnosed with NSCLC in Beijing Friendship Hospital Affiliated to Capital Medical University from January 2016 to December 2017 were retrospectively analyzed. Among 521 cases, 406 cases were postoperatively pathologically confirmed as non-lymph node and non-distant metastasis (non-metastasis group) and 115 cases were postoperatively pathologically confirmed as lymph node or distant metastasis (metastasis group). The preoperative FDP level and clinicopathological characteristics as well as the clinicopathological characteristics of NSCLC patients with different FDP levels were compared between the two groups. The correlation between preoperative FDP level and TNM staging was analyzed by using Spearman correlation analysis.Results:Among 521 NSCLC patients, 266 cases were female, 255 cases were male; the age [ M( Q1, Q3)] was 59 years (54 years, 65 years); 441 cases were adenocarcinoma and 70 cases were squamous cell carcinoma. The preoperative median FDP level was 2.78 mg/L (2.35 mg/L, 3.13 mg/L) and 2.99 mg/L (2.56 mg/L, 4.16 mg/L), respectively of NSCLC patients in non-metastasis group and metastasis group, and the difference was statistically significant ( Z = 6.13, P < 0.001). The preoperative FDP level was 2.56 mg/L (2.35 mg/L, 3.20 mg/L) and 2.99 mg/L (2.56 mg/L, 3.20 mg/L), respectively in the early-stage NSCLC (stage Ⅰ-Ⅱ) and advanced NSCLC (stage Ⅲ-Ⅳ) patients, and the difference was statistically significant ( Z = 8.42, P < 0.001). Spearman correlation analysis showed that preoperative FDP level was positively correlated with tumor diameter ( r = 0.287, P < 0.001). There was a positive correlation between preoperative FDP level and the number of metastatic lymph nodes in 115 patients with lymph node metastasis ( r = 0.679, P < 0.001). According to the preoperative median FDP (2.78 mg/L), all patients were divided into FDP ≤2.78 mg/L group and FDP >2.78 mg/L, and there were statistically significant differences in age, metastasis, tumor staging, tumor diameter, the metastatic number of lymph node and histological types of NSCLC patients in both groups (all P < 0.05). Conclusions:The increase of preoperative plasma FDP level may be related to the tumor metastasis and clinical stage of NSCLC patients

Objective To study the effect of acupuncture Zusanli on brain functional magnetic resonance imaging.Methods 96 healthy volunteers were randomly divided into acupoint group and non-acupoint group.The acupoint group received acupuncture Zusanli,and the non-acupoint group received manipulation,acupuncture and sham acupuncture.The functional brain imaging was determined by MRI,the brain functional images were compared between two groups.Results All subjects were matched with the end of the experiment,the acupoint group received acupoint stimulation,had obvious needling sensation,the non-acupoint group had mild needling sensation.The acupoint group activated 13 brain regions,non-acupoint group in 10 brain regions,the thalamus,pons,supramarginal gyrus in non-acupoint group without the activation.In the basal ganglia (28 cases vs.5cases) and temporal lobe (38cases vs.21cases) between the two groups were activated,the difference was statistically significant(x2 =36.250,P ＜ 0.05).In the temporal lobe,the left hemisphere response rate(73.68％) was significantly higher than the right hemisphere (36.84％),the difference was statistically significant (x2 =8.265,P ＜ 0.05).In the basal ganglia,left hemisphere activation (67.86％) was higher than that of the right hemisphere(42.86％),but the difference was not statistically significant (x2 =0.724,P ＞ 0.05).Conclusion The research of acupuncture by brain functional magnetic resonance imaging showed that Zusanli acupoint can activate the brain function area through brain regulation and treatment of body organs,so as to prove the existence of its own and meridian sensing characteristics.

Objective To investigate the effect of group cognitive behavioral therapy on anxiety and depression in patients with chronic heart failure ( CHF ) .Methods One hundred patients with CHF were recruited from January 2012 to December 2013 in cardiovascular department , and were divided into the intervention group and the control group , with 50 patients each .Comprehensive intervention including routine heart failure care and group cognitive behavioral therapy combined with other therapies was adopted on the patients in the intervention group .The Self-rating Anxiety Scale ( SAS ) and the Self-rating Depression Scale ( SDS) were used to compare the difference of anxiety and depression between groups .Results At the baseline, the incidence of anxiety was 25%, within which 11 patients had mild anxiety , and 10 patients had moderate anxiety, and 4 patients had severe anxiety.The incidence of depression was 39%, within which 19 patients had mild depression , and 14 patients had moderate depression , and 6 patients had severe depression .The score of SAS and SDS in the intervention group after intervention were (36.90 ±8.465) and (27.53 ±7.162), respectively, which were significantly lower than (40.91 ±8.019) and (36.78 ±10.562) in the control group (t=9.244,10.335, respectively;P<0.01).Conclusions Group cognitive behavioral therapy can effectively relieve the anxiety and depression in patients with chronic heart failure .
