Objective To Explore the feasibility and value of deep learning technology for quality control of echocardiography images.Methods A total of 180985 echocardiography images collected from Sichuan Provin-cial People's Hospital between 2015 and 2022 were selected to establish the experimental dataset.Two task models of the echocardiography standard views quality assessment method were trained,including intelligent recognition of seven types of views(six standard views and other views)and quality scoring of six standard views.The predictions of the models on the test set were compared with the results of the sonographer's annotation to assess the accuracy,feasibility,and timeliness of the runs of the two models.Results The overall classification accuracy of the stan-dard views recognition model was 98.90%,the precision was 98.17%,the recall was 98.18%and the F1 value was 98.17%,with the classification results close to the expert recognition level;the average PLCC of the six standard views quality scoring models was 0.933,the average SROCC was 0.929,the average RMSE was 7.95 and the average MAE was 4.83,and the prediction results were in strong agreement with the expert scores.The single-frame inference time after deployment on the 3090 GPU was less than 20 ms,meeting real-time requirements.Conclusion The echocardiography standard views quality assessment method can provide objective and accurate quality assessment results,promoting the development of echocardiography image quality control management towards real-time,objective,and intelligent.

Objective:To observe the effect of point application-invigorate the spleen and kidney, circulation of blood formula (PA) combined with five-animal exercise (FAE) on improving the nutritional status for asthenia of patients with dialysis, and provide evidence for the rehabilitation treatment of dialysis patients.Methods:According to the random number table method, a total of 80 patients treated with regular dialysis at Department of Nephrology, the Affiliated Hospital of Nanjing University of Chinese Medicine from April 2020 to December 2021 were randomly divided into experimental group and control group, with 40 cases in each group. Participants in the control group received regular dialysis, basic treatment and diet nursing (RBD). Participants in the experimental group received RBD plus PA+FAE. Labaratory test results, Subjective Global Assessment scale score and Traditional Chinese medicine symptom score were measured at baseline and 12-weeks after the intervention. The Fried Frailty scale score was measured at baseline, 4, 8, and 12 weeks after the intervention.Results:The control group aged (54.08 ± 11.34) years old, 23 males, 17 females; the experimental group aged (57.38±9.89) years old, 19 males, 21 females. After 4, 8 and 12 weeks of intervention, the Fried Frailty Scale scores of the experimental group at different time points were 2 (2, 2), 1 (1, 2) and 1 (0, 1), respectively, lower than 3 (2, 4), 2 (2, 3) and 2 (2, 3) of the control group, and the differences in time effect, inter-group effect and interaction effect were statistically significant ( F=105.76, 18.38, 46.67, all P<0.01). Further pairwise comparisons within groups indicated significant differences of Fried Frailty scale scores at different time points ( Z=-2.78, -4.01, -6.08, all P<0.01). After 12-week of intervention, the results of hemoglobin, serum albumin and serum prealbumin were (107.88 ± 15.58) g/L, (39.10 ± 4.92) g/L, and (289.36 ± 72.05) mg/L in the experimental group, respectively, higher than (100.15 ± 17.62) g/L, (36.93 ± 4.72) g/L, (255.63 ± 75.35) mg/L in the control group ( t=-2.08, -2.01, -2.05, all P<0.05). Subjective Overall Assessment scale was found a significant difference between the 2 groups ( χ2=10.91, P<0.01): the number of grade A (good nutrition) and B (mild to moderate malnutrition) were 36 and 4 in the experimental group and 23 and 17 in the control group. Traditional Chinese medicine symptom score was (4.68 ± 2.50) in the experimental group, lower than (9.58 ± 4.40) in the control group ( t=6.13, P<0.01). Conclusions:Point application-invigorate the spleen and kidney and circulation of blood formula combined with five-animal exercise can effectively improve the nutritional status of dialysis patients and reduce the weakness of patients

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

OBJECTIVE: To observe the effect of preoperative, intraoperative and postoperative electroacupuncture (EA) intervention on postoperative urination function in patients with mixed hemorrhoid surgery. METHODS: A total of 240 patients with mixed hemorrhoid surgery under lumbar anesthesia were randomly divided into an EA preconditioning group (group A, 60 cases, 9 cases dropped off), an intraoperative EA group (group B, 60 cases, 4 cases dropped off), a postoperative EA group (group C, 60 cases, 6 cases dropped off), and a non-acupuncture group (group D, 60 cases, 3 cases dropped off). In the groups A, B and C, EA was exerted at Zhongliao (BL 33) and Huiyang (BL 35) , with disperse-dense wave, 4 Hz/20 Hz in frequency, and lasting 30 min, at 30 min before lumbar anesthesia, immediately after lumbar anesthesia and 6 h after surgery, respectively. No EA intervention was performed in the group D. The postoperative urination smoothness score in each group was observed 24 h after surgery. The first urination time, first urination volume, urine residual volume after first urination were recorded, and incidence of indwelling catheterization, postoperative visual analogue scale (VAS) score, number of remedial analgesia, and the incidence of postoperative nausea and vomiting were observed in each group. RESULTS: In the groups A, B and C, the postoperative urination smoothness scores were superior to the group D (P<0.05), and the time of first urination was earlier than the group D (P<0.05). In the group C, the time of first urination was earlier than the group A and the group B (P<0.05), the first urination volume was higher than the group D (P<0.05), and the urine residual volume after first urination was lower than the group D (P<0.05). There was no significant difference in the incidence of indwelling catheterization and postoperative nausea and vomiting among the 4 groups (P>0.05). The VAS scores of the group A, B and C were lower than that in the group D (P<0.05), and the number of remedial analgesia cases was lower than that in the group D (P<0.05). CONCLUSION EA intervention could promote the recovery of urination function and relieve postoperative pain in patients with mixed hemorrhoids surgery. Early postoperative EA intervention is more conducive to the recovery of urination function.

Objective To investigate the effect of rehabilitation training combined with acupuncture ( RTA) on upper limb function of stroke patients by Kinect. Methods Stroke patients with upper limb dysfunction werrandomly divided into control group (rehabilitation training) and treatment group ( RTA), with 15 cases in each group. The modified Barthel Index ( MBI), Fugl Meyer assessment ( FMA), and Wolf motor function test (WMFT) were compared between two groups before and after treatment. The changes in motor time ( MT), motor unit number (MUN), index of curvature (IC), elbow flexion angle (EFA), shoulder flexion angle (SFA),and shoulder adduction angle ( SAA) during three actions, namely, placing forearm on the table, extending elbow and drinking water, were evaluated by Kinect and then compared between two groups before and after treatment. Results After 6 weeks of intervention, the scores of MBI, FMA, WMFT and elbow extension in treatment group were higher than those in control group (P<0. 05). The scores of MBI, FMA, WMFT and three actions after treatment were higher than those before treatment (P<0. 05). For three actions, the improvement of MT, MUN, IC, EFA, SFA, and SAA in treatment group were better than those in control group ( P< 0. 05). Compared with pre-treatment, for the action of forearm placement on the table and elbow extension, both treatment group and control group showed an increase in EFA (P<0. 05), and a decrease in MT, MUN, IC, SFA and SA (P<0. 05). For the action of drinking water, both treatment group and control group showed an increase in EFA and SAA (P< 0. 05), and a decrease in MT, MUN, IC and SAA ( P< 0. 05). Conclusions RTA can improve the upper limb function of stroke patients. Kinect can accurately reflect the changes in upper limb function of stroke patients, and it is suitable for clinical work.

In recent years, the prevalence of hyperglycemia has been increasing, and patients’ bodies have been seriously damaged. Compared with conventional Western drugs, natural products have fewer adverse reactions and delay the complications of hyperglycemia. As a valuable natural product resource, Small-leaf Kuding (SLK) contains various beneficial components for the human body. The aim of this study was to study the regulation effect of SLK extract at different doses on blood glucose metabolism in hyperglycemic mice. Lipopolysaccharide and streptozotocin were used to induce hyperglycemia in mice. Extract of SLK were administered intragastrically at low, medium, and high doses (5 g·kg

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

Renal pelvic hemangioma is a rare benign tumor, presenting with intermittent, total, painless, gross hematuria, accompanied by low back pain, abdominal pain or other symptoms in some cases. Four cases of pyelonephric hemangioma were treated, which were misdiagnosed as malignancy before surgery. For middle-aged patients with intermittent hematuria, if the imaging data cannot rule out renal pelvic hemangioma, it is recommended to perform renoscopy, renal artery angiography or renal puncture biopsy. For patients diagnosed with renal pelvic hemangioma, either partial nephrectomy, ureteroscopic cauterization, or selective renal artery embolization can achieve good results.

Objective:To explore the diagnosis, surgical methods and therapeutic effect of primary duodenal malignant tumor.Methods:The clinical data of 116 patients with primary duodenal malignant tumor from January 2010 to December 2018 were retrospectively analyzed.Results:Among 116 patients, adenocarcinoma was in 74 cases, interstitial tumor was in 25 cases, carcinoid was in 9 cases, the others was in 8 cases. Before operation, duodenoscopy was performed in 107 cases, and CT examination was performed in 76 cases. There were 57 cases of pancreaticoduodenectomy, 15 cases of duodenal segmental resection, 13 cases of subtotal gastrectomy and duodenal bulbar resection, 13 cases of duodenal partial resection, and 18 cases of palliative short circuit operation. The total incidence of postoperative complication was 31.9% (37/116), including pancreatic fistula in 8 cases (grade B 5 cases, grade C 3 cases), biliary fistula in 6 cases, abdominal infection in 5 cases, pulmonary infection in 4 cases, intestinal fistula in 3 cases, delayed gastric emptying in 3 cases, and hemorrhage in 8 cases. Four cases (3.4%) died during the perioperative period. Single factor Cox regression analysis result showed that the postoperative survival time was related to the tumor differentiation degree, operation method, tumor infiltration degree and lymphatic metastasis ( P<0.05 or <0.01); multi-factor Cox regression analysis results showed that the operation method, tumor infiltration degree and lymphatic metastasis were the independent risk factors for the postoperative survival time of patients with primary duodenal malignant tumor ( P<0.05). The patients were followed up until June 2021, and 9 cases were lost to follow-up. Kaplan-Meier survival curve analysis result showed that the postoperative overall 1-,3- and 5-year survival rates were 82.11%, 57.56% and 33.11%, respectively. Conclusions:Adenocarcinoma is the main primary malignant tumor of duodenum. Duodenoscopy and CT are the main examination methods. Radical resection is the most effective treatment for primary duodenal malignant tumor, and pancreaticoduodenectomy is the first choice. Surgical method, tumor infiltration degree and lymphatic metastasis are the independent risk factors affecting the prognosis of patients.

Objective To investigate the effects of CTNND2 knockout on cerebellar neuronal development and motor function in mice, as well as its possible mechanisms. Methods The mice were divided into two groups (n = 10 in each group), all of them were 7 weeks old : wild-type (WT) C57BL/6J mice were treated as control group, and homozygous of CTNND2 knockout (CTNND2 7) mice were treated as experimental group, the genotype of CTNND2 7 mice were detected with PCR. The motor function of two groups were detected by beam walking test, hanging wire test and gait analysis test. The changes of cerebellar Purkinje cells were detected by immunofluorescence staining and Golgi staining. Western blotting was performed to detect the expression levels of synapse-associated proteins phosphorylated synapsin 1 (p-Synl), synapsin 1 (Synl), ELKS and postsynaptic density protein 95(PSD95), as well as phosphoinositide 3-kinase (PI3K), phosphorylated protein kinase B (p-Akt), protein kinase B (Akt), phosphorylated mammalian target of rapamycin (p-mTOR) and mammalian target of rapamycin (mTOR). Results Compared with the WT mice, except the increase in time to traverse the beam, there was a decrease in the proportion of pass on the beam, or latency to fall from the hanging wire, or score of hanging wire, or fore-stride length and hind-stride length of CTNND2 7 mice. There was also a decrease in numbers of Purkinje cells and its dendritic arborization in cerebellum of CTNND2 7 mice. The ratio of p-Synl/ Synl, p-Akt/Akt and p-mTOR/mTOR, as well as the expression levels of ELKS, PSD95 and PI3K were lower than those of WT mice. Conclusion CTNND2 knockout can affect the number and dendritic architecture of Purkinje cells, as well as synthesis of synapse-associated proteins in cerebellum by down-regulating PI3K/Akt/mT0R signaling pathway, resulting in cerebellar developmental disorder, thereby affecting motor function of mice.
