Extracorporeal membrane oxygenation (ECMO) is a key continuous extracorporeal life support technology that can partially or completely replace a patient's cardiopulmonary function, thereby winning valuable time for the diagnosis and treatment of the primary disease. With the widespread application of ECMO, the need for transport has increased. However, during transfers, the standard heater unit is often large and inconvenient to carry, while alternative warming measures tend to be ineffective. This frequently leads to complications such as hypothermia or the inability to maintain body temperature, which can seriously affect the patient's prognosis. In response to this challenge, the medical and nursing staff of the critical care medicine department at Zhongda Hospital Affiliated to Southeast University jointly designed an insulation device for ECMO transport pipelines. The device was successfully granted a National Utility Model Patent of China (patent number: ZL 2021 2 0653569.3). It primarily consists of key components such as a heating pad, velcro straps, a cover layer, a backing layer, an electric heating layer, and a wiring plug. Its advantages include portability, the ability to effectively wrap around and warm the ECMO circuit during transit, and a reduction in the incidence of hypothermia-related complications. Furthermore, its transparent material design allows for real-time monitoring of the ECMO system's status, making it both economical and practical.

Objective To observe the value of radiomics models based on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced hepatobiliary phase(HBP)MRI for assessing clinical pathological stage of hepatic fibrosis(HF).Methods Data of 240 patients with pathologically/clinically diagnosed and clinical pathological staged HF who underwent Gd-EOB-DTPA enhanced MR examination were retrospectively analyzed.The liver-to-muscle signal intensity ratio(SIR1)and liver-to-spleen signal intensity ratio(SIR2)were measured based on HBP images.Radiomics features of HBP images were extracted and screened to construct radiomics models.The signal intensity ratio(SIR)-radiomics combined models were constructed based on SIR and radiomics signatures.Receiver operating characteristic(ROC)curves were drawn to evaluate the efficacy of each model for assessing clinical pathological stage of HF.Results The area under the curve(AUC)of SIR1 and SIR2 models for assessing clinical pathological stage of HF were 0.63-0.70 and 0.65-0.71,respectively.The most effective radiomics model for assessing HF,significant HF,advanced HF and early cirrhosis was support vector machine(SVM),SVM,light gradient boosting machine and K-nearest neighbor model,respectively,with the AUC in validation set of 0.87,0.82,0.81 and 0.80,respectively,while the AUC of SIR-radiomics combined models in validation set of 0.88,0.82,0.82 and 0.81,respectively.Conclusion The radiomics models based on Gd-EOB-DTPA enhanced HBP MRI were helpful for assessing clinical pathological stage of HF.Combining with HBP SIR could improve their efficacy.

Objective To measure the change of facial volume maintenance rate after autologous fat grafted for repaired progressive facial hemiatrophy by using three-dimensional digital technology.Methods 3D scanner was used to acquire facial data in 10 patients with progressive facial hemiatrophy before operation;Mimics 17.0 software was used to reconstruce patients' facial 3D model and to calculate the volume of facial tissue defect;autologous fat was grafted to repair facial deformity.The facial volume maintenance rate was calculated in all the patients 3 months and 6 months after operation.Results We had performed facial 3D data acquisition and facial repaired with autologus fat grafted in 10 patients;patients' facial morphology was improved.The mean facial volume maintenance rate was (35.80±3.44)％ in 3 months and (27.82±3.80)％ 6 months after surgery.Conclusions The mean facial volume maintenance rate in postoperative 3 months is inferior to that in 6 months in single autologous fat grafted for repairing progressive facial hemiatrophy.

Hepatitis C virus (HCV) is a blood-borne virus transmitted through contact with blood and blood products,and it is a major cause of liver cirrhosis and hepatocellular carcinoma.Many epidemiological studies have confirmed the association between HCV infection and renal disease.Membranoproliferative glomerulonephritis associated with mixed cryoglobulinemia is the most common type of HCV-related renal disease manifesting as nephropathy or nephritic syndrome,proteinuria,hematuria,and reduced glomerular filtration rate.The treatment of HCV-related renal disease includes antiviral therapy,B cell clearance,and non-specific immunosuppressive therapy.At the same time,the launch of rnew antiviral drugs has brought hope to the patients who cannot tolerate conventional regimens.This article reviews the research advances in epidemiology,clinical manifestations,pathogenesis,and treatment of HCV-related renal injury.

OBJECTIVETo compare the effect difference for stroke between meridian-collateral diagnosis and therapy byand conventional acupuncture with syndrome differentiation.

METHODSTotally 148 patients were assigned into an observation group(72 cases) and a control group(76 cases) by random number table,with 10 cases dropping out in the observation group. In the observation group,meridians were examined and differentiated and then the treating meridians and acupoints were defined. Corresponding acupuncture was used according to them. In the control group,acupuncture was applied at acupoints by internal differentiation and experience. Treatment was given once a day and five times a week,with total 20 times. The motion function of limbs and coloboma degree of nerve function were assessed by Fugl-Meyer score and National Institutes of Health Stroke Score(NIHSS) before and after treatment as well as at three-month follow-up.

RESULTSAfter treatment,the Fugl-Meyer scores increased and the NIHSS scores decreased in the two groups compared with those before treatment(all<0.05). At follow-up three months after treatment,Fugl-Meyer score upgraded in the observation group (<0.05) and NIHSS score declined in the two groups (both<0.01) than those before treatment,and NIHSS scores were statistically different between the two groups(<0.05).

CONCLUSIONSMeridian-collateral diagnosis and therapy byhas better long-term efficacy when it is compared with conventional acupuncture with syndrome differentiation for motion function of limbs and nerve function of stroke.

Objective To study effects of Rupixiao granules on contraction of uterus of mice in vitro. Methods Mouse model with isolated uterine contraction was established. The mice pretreated with estradiol benzoate were sacrificed and then the uteri were taken out. The normal contractions were recorded by the biological function system. Effects of 10, 20, 30, 40, 50, 60 mg.mL-1 Rupixiao granules on spontaneous and oxytocin-induced (5 U.L-1) uterine contractions were recorded,inhibition of Rupixiao granules on mean constriction amplitude,constriction frequency and contraction activity of pitocin-pretreated uterus was observed and the inhibition rates were calculated. Results Compared with the baselines, the amplitude, frequency, activity of spontaneous uterine contraction were significantly down-regulated by Rupixiao solution at a range of 10-60 mg.mL-1 ,as well as it could inhibit oxytocin-induced spasmodic contraction of isolated uterus at 10-50 mg . mL-1 ( P<0. 01 ) . Conclusion The Rupixiao granules inhibits spontaneous contraction of isolated mouse uteri and oxytocin-induced spasm of uterine smooth muscle in vitro.

Objective:To investigate the anti-inflammatory and analgesic effects of Rupixiao granules. Methods:Activity of Rupixi-ao granules against xylene-induced ear edema in mice was measured to evaluate the anti-inflammatory effect, while the analgesic effect was evaluated by acetic acid induced writhing test and hot plate test in mice. Results:Compared with the control group, Rupixiao gran-ules groups (1. 0, 2. 0 and 4. 0 g·kg·d-1) could significantly inhibit ear swelling in mice(P<0. 05 or 0. 001), and reduce the acetic acid induced writhing times(P<0. 01 or 0. 001). Rupixiao granules at medium and high dose could significantly increase the pain thresh-old of mice in the hot plate test. Conclusion:Rupixiao granules exhibit significant anti-inflammatory and analgesic activities.

PURPOSE: The purpose of this study was to develop and preliminarily evaluate the reliability and validity of the Symptom-Management Self-Efficacy ScaleeBreast Cancer (SMSES-BC) related to chemotherapy. METHODS: The study included three stages. This paper presents the results of stage 2 and stage 3. In total, 34 items in the SMSES-BC were found during stage 1 from qualitative findings, a literature review, and expert suggestions; the 34 items were used for the psychometric properties test. Test-retest reliability and Cronbach alpha were assessed in the first sample, which included 45 participants for the pilot test (stage 2). The second sample, which included 152 patients, was used to assess the construct validity and concurrent validity (stage 3). RESULTS: The pilot test results revealed a test-retest reliability of .73 (p < .001) and Cronbach alpha coefficient of .96 for the total scale. Three factors (managing chemotherapy-related symptoms, acquiring problem solving, and managing emotional and interpersonal disturbances) were identified from exploratory factor analysis. Correlation coefficient r was .40 (p < .001), which supported the association between SMSES-BC and the General Self-Efficacy Scale for concurrent validity. CONCLUSIONS: The study results demonstrate acceptable reliability and validity for the SMSES-BC that was developed for measuring symptom-management self-efficacy related to chemotherapy for patients with breast cancer. This study suggests further research to validate the construct of the SMSES-BC.
