Objective To determine the change in humeral head anterosuperior migration after releasing the coracoacromial l igament in shoulders from cadavers with simulated intact or irreparable teared rotator cuff, to provide biomechanical basis for preserving the coracoacromial l igament or not during hemiarthroplasty. Methods Twelve freshfrozen cadaveric glenohumeral joints of adult preserving the scapula, upper 2/3 of the humerus, articular capsule and the coracoacromial l igament, were divided into 2 groups. The suprascapularis was preserved in group A (6 shoulders) and excised in group B (6 shoulders). Positioning the joint in a combination of 30° extension, 0° abduction and 30° external rotation, and imposing a 50 N axial compressive load to the humeral shaft, the anterosuperior displacement of the humeral head weremeasured before and after excising the coracoacromial l igament. Results In group A, the displacement of the humeral head was (5.96 ± 0.77）mm with intact coracoacromial l igament and (6.83 ± 0.84）mm after transecting the l igament. In group B, the displacement of the humeral head was (8.07 ± 2.46）mm with intact coracoacromial l igament and (9.92 ± 3.29）mm after transecting the coracoacromial l igament. So the mean increase of anterosuperior migration of the humeral head was (0.88 ± 0.34) mm (P lt; 0.01) in group A, and (1.85 ± 0.99) mm (P lt; 0.01) in group B, which was greater than the former (P lt; 0.05). Conclusion The coracoacromial l igament restrained anterosuperior translation of the humeral head, especially for patients with rotator cuff deficiency, so it should be preserved as far as possible during hemiarthroplasty.
Objective To evaluate the efficacy of Wechat combined with continuing nursing on the quality of life of epilepsy children with ketogenic diet, parents' mood and the time commitment of medical staff. MethodsData were collected from 140 children with intractable epilepsy with ketogenic diet admitted to the Department of Neurology, Children's Hospital Affiliated to Chongqing Medical University from November 2014 to June 2022, including 116 males and 24 females, with an average age of (8.42±2.44) years. The random sampling method was divided into control group (continuing nursing) 71 cases, intervention group (Wechat combined with continuing nursing) 69 cases. The quality of life of the children (QOLCE-16) in the two groups was compared before discharge and 3 months after discharge, as well as parental anxiety (SAS), depression (SDS), and the amount of time medical staff spent with both groups. ResultsThere was no difference in the quality of life and parental emotion between the two groups before intervention. After 3 months, the quality of life of the two groups was significantly improved [(43.59±10.00) vs. (40.14±10.44), P<0.05], and the QOLCE-16 score of the intervention group was higher than that of the control group (P<0.05). The parental mood SAS and SDS in both groups were significantly improved [(37.19±2.90) vs. (50.85±3.76), (40.14±3.52) vs. (49.29±3.37), P<0.01], and the SAS and SDS scores of anxiety and depression of parents in the intervention group were lower than that of the control group (P<0.01). Medical staff spent more time on intervention group [(136.17±7.43) vs. (65.55±7.48), P<0.01]. ConclusionContinuing nursing can improve the quality of life of children with ketogenic diet and the negative emotions of their parents. The combination of Wechat and continuing nursing can further strengthen this positive effect, and requires more time of medical staff.

Objective To investigate the safety and feasibility of preoperative non-indwelling catheter in primary unilateral total knee arthroplasty (TKA) without tourniquet . Methods From January 2016 to January 2017, a total of 60 patients undergoing primary unilateral TKA surgery were randomly divided into preoperative non-indwelling catheter group (group NIC, n=30) and indwelling catheter group (group IC, n=30) . The patients in group NIC were not retained catherter, and the patients in group IC were retained catherter. All patients did not use tourniquet. The time of first urination, the volume of first urination, and the occurrence of urine retention, urinary irritation symptoms and urinary tract infection of patients in two groups were analyzed. The incidence of venous thrombosis of the lower extremity was also recorded. Results There were statistical differences (P<0.05) between group NIC and group IC in the time of first urination [(3.2±0.6) vs. (4.5±1.8) hours] and urine volume [(262.5±29.4) vs. (391.6±50.2) mL], but there was no significant difference (P>0.05) between the two groups in urinary retention (6.7% vs. 16.7%), urinary tract irritation (33.3% vs. 23.3%), or urinary tract infection (0.0% vs. 16.7%). Conclusion Preoperative non-indwelling catheter in primary unilateral TKA without tourniquet is safe and feasible.
Objective Compare and analyze the value of β-hydroxybutyrate from two kinds of blood ketone instruments (Optium Xceed blood ketone body instrument from American Abbott laboratories and TBS-1 blood ketone body instrument from Beijing Yicheng company), and provide instructions for clinical applications. Methods Select 7 children patients with epilepsy which have a response to ketogenic diet. The two kinds of blood ketone instruments were used to test blood ketone value of whole blood synchronously in five different periods, and compare the 70 results. Results The measuring results obtained from these two kinds of blood ketone body instruments have statistical difference significantly. The value acquired from TBS-1 blood ketone body instrument is lower than that from Optium Xceed blood ketone body instrument. Measurements using a paired t test, the value of t=12.14, P<0.01. The results from two kinds of blood ketone body instruments are statistically significant. Conclusion The values from 2 kinds of blood ketone instruments are different, which would influence the clinical judgment. At present, the key problem is that there is lack of special blood ketone measure technology for patients with ketogenic diet. How to improve the measure accuracy of high-level blood ketone value remains the future work.
Objective To explore the clinicopathological characteristics which were associated with lymph node metastases in early gastric cancer patients. Methods Clinical data of 187 early gastric cancer patients who received surgical treatment in The Second People’s Hospital of Jiaozuo between January 2009 and January 2016, were retrospectively analyzed, and then exploring the clinicopathological characteristics which were associated with lymph node metastases in early gastric cancer, including age, gender, tumor location, diameter of tumor, number of tumor, depth of invasion, macroscopic type, histological type, venous invasion, and local ulcer. Results In this study, 187 patients with early gastric cancer were included, and lymph node metastasis was detected in 32 patients (17.1%). Results of multivariate logistic regression analysis showed that, lymph node metastasis was significantly closely related with diameter of tumor (OR=2.080,P=0.022), depth of invasion (OR=21.048,P=0.001), histological type (OR=3.507,P=0.018), venous invasion (OR=2.406,P=0.009), and local ulcer (OR=2.738,P=0.001), patients with diameter of tumor larger than 2 cm, infiltration depth of submucosa, histological types of undifferentiated type, vascular infiltration, and local ulcer had higher lymph node metastasis rate. Conclusion The clinicopathological characteristics, including diameter of tumor, depth of invasion, histological type, venous invasion, and local ulcer are risk factors for lymph node metastasis of early gastric cancer patients, which should be paid high attention.
Objective To evaluate the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in treating stroke patients with motor dysfunction. Methods The Cochrane Library, MEDLINE, EMbase, CBM, CNKI and WanFang Data were searched from inception to January 2012, and the references of the included studies were also retrieved to collect the randomized controlled trials (RCTs) on rTMS in treating stroke patients with motor dysfunction. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan 5.0.2 software, and evidence quality and recommendation level were assessed using the GRADE system. Results A total of 11 RCTs involving 376 patients were included. The results of meta-analysis (including 3 RCTs, low quality) showed that, compared with the routine rehabilitation treatment, 2 to 4 weeks of rTMS was much beneficial to stroke patients with motor dysfunction, with significant differences (WMD=11.02, 95%CI 2.56 to 19.47). The other 8 studies only adopted descriptive analysis accordingly. Conclusion It is still uncertain of the effectiveness of rTMS in improving motor dysfunction of stroke patients, so rTMS should be applied with caution in clinic.
ObjectiveTo explore the selection and application value of preoperative stereotactic localization in the surgical treatment of secondary hyperparathyroidism.MethodsThe preoperative ultrasound, CT, and methoxyisobutylisonitrile (MIBI) scan data of 54 patients with secondary hyperparathyroidism confirmed by pathological examination in the Department of General Surgery of the 900th Hospital of the Joint Logistics Team from September 2016 to January 2020 were retrospectively analyzed, to explore the localization accuracy of the three methods alone or in combination.ResultsIn this study, a total of 207 parathyroids were detected, 1 was misdiagnosed (ectopic thymus),9 were missed, and 216 parathyroids were removed. The preoperative localization accuracy of CT, ultrasound, and MIBI was the highest (95.39%, 207/217), followed by ultrasound and MIBI (93.55%, 203/217) and CT+MIBI (89.40%, 194/217), compared with other single or two methods, the differences were statistically significant (P<0.05). The accuracy of CT combined with ultrasound localization (82.49%, 179/217) was slightly higher than that of MIBI scan alone (78.80%, 171/217), but the difference was not statistically significant (P=0.060). Although the location accuracy of MIBI scan was slightly higher than that of ultrasound localization (77.88%, 169/217), the difference was not statistically significant (P=0.084).ConclusionIn order to maximize the accuracy of preoperative stereotactic localization of secondary hyperparathyroidism, ultrasound, CT, and MIBI should be combined.
