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 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.

It is generally considered that various regulatory activities between genes are contained in the gene expression datasets. Therefore, the underlying gene regulatory relationship and the biologically useful information can be found by modeling the gene regulatory network from the gene expression data. In our study, two unsupervised matrix factorization methods, independent component analysis (ICA) and nonnegative matrix factorization (NMF), were proposed to identify significant genes and model the regulatory network using the microarray gene expression data of Alzheimer's disease (AD). By bio-molecular analyzing of the pathways, the differences between ICA and NMF have been explored and the fact, which the inflammatory reaction is one of the main pathological mechanisms of AD, is also emphasized. It was demonstrated that our study gave a novel and valuable method for the research of early detection and pathological mechanism, biomarkers' findings of AD.

Objective To evaluate the accuracy of pedicle guide device for the placement of the pedicle screws. Methods Pedicle guide device was designed and made for the anatomical trait of pedicle. The 3-Danatomical data of the thoracic pedicles were measured by multislice spiral CT in two embalmed human cadaveric thoracic pedicles spine(T1 -T10). Depending on transverse section angle(TSA) and sagittal section angle(SSA) of pedicle axis, the degree of horizontal dial and sagittal dial were adjusted in the guide device. The screws wereinserted bilaterally in the thoracic pedicles by using the device. After pulling the screws out, the pathways were filled with contrast media. The TSA and SSA of developed pathways were measured. Results Analysis of the difference between pedicle axis and developed pathway was of no statistical significance(P＞0.05). Conclusion The guide device could be easilyoperated and guarantee high accuracy of the pathways of screws and the incidence of pedicle penetration could be significantly reduced.
ObjectiveTo evaluate liver perfusion in pregnant women with hepatitis between 13 and 41 weeks of gestation by three-dimensional color power Doppler angiography (3D-CPA) vascular indexes. MethodsThis study involved 73 pregnant women with hepatitis and 44 healthy pregnant women who had the pregnancy examination between February 2012 and June 2013. We sampled in the area which was near the right lobe of the pregnant women liver's portal vein branch, and obtained the vascularization index (VI), flow index (FI) and vascularization flow index (VFI) via the virtual organ computer-aided analysis (VOCAL) method. Then, we compared the liver perfusion differences between the pregnant women with hepatitis and healthy pregnant women. ResultsThe hepatic flow indexes obtained by 3D-CPA were significantly different between the HBV-DNA viral load and the control groups. The cutoff values of the three vascular indexes of patients with hepatitis with HBV-DNA viral load and the healthy pregnant women were respectively VI=8.760 (P<3×10-4); FI=22.180 (P<6×10-7); and VFI=1.575 (P<3×10-5). ConclusionApplication of the 3D-CPA on liver perfusion may differentiate pregnant women with hepatitis B from normal ones, thus offer a support for clinical prevention and treatment for pregnant women with hepatitis B.
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.
