Objective] To probe into a case of bilingual classroom teaching model in a TCM university, expect to find that if the current bilingual teaching could achieve the goal of raising ability both in disciplinary knowledge and language competence advocated by content-based instruction teaching idea, explore the possible problems and propose some corresponding solutions. [Methods] Empirical research method was used to execute quantification statistics on classroom teaching activity and the discourse between teacher and students, combining with qualitative data from questionnaires and interviews. By the methods above, this paper expected to embody the present situation and problems of the bilingual teaching in a TCM university. [Results] For classroom teaching both in disciplinary knowledge and language forms, there was a phenomenon that input and output forms were single, so that the function of other effective classroom activities was ignored. It was still a teacher-centered classroom with teacher as the main body of classroom. Students' insufficient competence and teachers' limited level were still a main problem to be solved. Compared with time of disciplinary knowledge, focus on language was less and the output time of language was compressed. [Conclusion] It's necessary to richen the classroom teaching mode. Cognition of both teacher and students on bilingual teaching shall change, giving consideration to disciplinary knowledge and language competence, overcoming language weakness and facilitating the two-sided promotion.

Objective:To investigate the correlation between white matter hyperintensities (WMHs) and stroke etiology classification in patients with acute isolated penetrating artery territory infarction.Methods:Patients with first-ever acute isolated penetrating artery territory infarction admitted to the Department of Neurology, the Affiliated Hospital of Xuzhou Medical University from January 2017 to May 2020 were enrolled retrospectively. According to the Chinese Ischemic Stroke Subclassification (CISS) system, they were divided into large artery atherosclerosis (LAA) and perforating artery disease (PAD). According to the distribution of infarcts, they were divided into lenticulostriate artery (LSA) territory infarction and paramedian pontine artery (PPA) territory infarction. The demographics, vascular risk factors, baseline clinical data, WMHs location, and Fazekas Scale scores were documented. Multivariate logistic regression analysis was used to identify the independent influencing factors of stroke etiology classification. Results:A total of 440 patients with acute isolated penetrating artery territory infarction were enrolled, including 120 (27.3%) in the LAA group, and 320 (72.7%) in the PAD group; 213 (48.4%) with LSA territory infarction, and 227 (51.6%) with PPA territory infarction. The proportion of patients with total Fazekas score 3-6 and periventricular WMHs (PWMHs) score 2-3 in the PAD group was significantly higher than those in the LAA group (all P<0.05). In patients with LSA territory infarction, the proportion of the patients with hypertension, WMHs total Fazekas score 3-6 and PWMHs score 2-3 in PAD subgroup was significantly higher than those in the LAA subgroup, while the proportion of the patients with hyperlipidemia was significantly lower than that in LAA subgroup (all P<0.05). In patients with PPA territory infarction, the levels of low-density lipoprotein cholesterol and homocysteine in the PAD subgroup were significantly lower than those in the LAA subgroup. Multivariate logistic regression analysis showed that PWMHs score 2-3 was an independent correlation factor of PAD (odds ratio [ OR] 2.220, 95% confidence interval [ CI] 1.085-4.541; P=0.029). In patients with LSA territory infarction, hyperlipidemia was independently correlated with LAA ( OR 0.432, 95% CI 0.192-0.972; P=0.042), and PWMHs score 2-3 was independently correlated with PAD ( OR 3.846, 95% CI 1.193-12.397; P=0.024). In patients with PPA territory infarction, higher low-density lipoprotein cholesterol ( OR 0.660, 95% CI 0.494-0.883; P=0.005), homocysteine ( OR 0.958, 95% CI 0.930-0.987; P=0.005) and C-reactive protein ( OR 0.987, 95% CI 0.977-0.997; P=0.008) were independently correlated with LAA. Conclusions:WMHs are common in patients with acute isolated perforating territory infarction caused by LAA and PAD, and more severe PWMHs suggest that PAD is more likely to be the cause of the acute isolated perforating territory infarction, especially in patients with LSA territory infarction.

Objective To investigate the maternal and fetal outcomes of pregnant women with subclinical hypothyroidism, and clinical observation of thyroxine replacement. Methods From March 2014 to March 2015, the clinical records of 216 women with subclinical hypothyroidism(including 166 cases with thyroxine replacement), and hypothyroidism(n=69)during pregnancy who delivered at our hospital were reviewed. The maternal complications and neonatal outcomes were compared with 406 healthy women who delivered during the same period. Results The age, number of fetus, and morbidity rate of gestational hypertension were without significant differences in those groups. The morbidity of gestational diabetes in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(13.4%, 17.4% vs 0.2%, P<0.05). The rate of thyroid peroxidase antibody and thyroglobulin antibody positive in subclinical hypothyroidism group and hypothyroidism group were significantly higher than those in control group(26.9%, 23.2% vs 9.9%; 15.7%, 23.2% vs 8.1%, all P<0.05). No matter treated or not treated in subclinical hypothyroidism group, the preterm birth, Apgar score, low birth weight, birth defects, and infant congenital hypothyroidism were without significant differences as compared to the control group(P>0.05). Further compared those between treated and untreated subclinical hypothyroidism, the results were also without significant difference(P>0.05). Conclusions Subclinical hypothyroidism had no significant influence on pregnancy outcomes and perinatal events. Thyroxine replacement in subclinical hypothyroidism pregnant women also had no significant influence on pregnancy outcomes and perinatal events.

Objective: To improve the clinical outcomes and critical care quality for pediatric extracorporeal membrane oxygenation (ECMO), the multidisciplinary team including doctors, nurses and respiratory therapist designed a daily checklist for patients with ECMO and evaluated the effect of the checklist. Methods: A daily checklist for ECMO patients was designed based on the expert consensus and multi-centers relevant researches. ECMO patients from January 2015 and May 2017 in the pre-application group, while the other patients from June 2017 to December 2018 in the post-application group were compared in the clinical outcomes. Results: All 78 pediatric patients used the venoarterial extracorporeal membrane oxygenation (VA-ECMO) including 27 patients in the pre-application group and the other 51 patients in the post-application group. The mortality rate was 49.02%(25/51) in the post-application group and 81.48%(22/27) in the pre-application group, the differences were significant (χ²=7.768, P=0.005). The rates of central line-associated bloodstream infection, pressure injury and the body weight change was 2/5, 4/5, -2.70(-3.50--2.05) in the pre-application group and 3.85%(1/26), 26.92%(7/26), -0.09(-1.00-0.00) in the post-application group,the differences were significant (χ²=4.505, 5.161, Z=3.252, P<0.05 or 0.01). Conclusions It is helpful for clinical staff to follow up the progress of the multiple organs when using the daily checklist, to facilitate team communication for, and to improve nursing management through setting the daily targets for individual VA-ECMO patients.

Objective:pH low insertion peptide (pHLIP)-variant 7 (var7)-fluorescein isothiocyanate (FITC) was used to explore an accurate imaging tool that targeted burn wounds to better perform burn debridement.Methods:Twelve rat models of burn wound were established and pHLIP-var7-FITC with different concentrations (0.5, 1.5 and 2.0 mg/ml) were injected from the rat tail vein for in vivo fluorescence imaging. By determining the concentration of fluorescent conjugates to the burn wound, the scope of wound injury necrosis was judged by combining pathological sections, and its residue and toxicity in important organs such as heart, liver, kidneys, and brain were detected. The Kruskal-Wallis rank sum test, Bonferroni correction method and one-way analysis of variance were used for data analysis. Results:Within 24 h, the fluorescence photons per unit area of the burn wound in the group of 0.5 mg/ml, 1.5 mg/ml and 2.0 mg/ml were 1.49(1.31, 1.65), 2.46(1.88, 2.68), 2.77 (1.94, 3.10)×10 7 p·s -1·cm -2·Sr -1, with significant differences in the overall distribution of fluorescence photons ( H=73.55, P<0.001). The fluorescence intensity was stronger in the group with higher concentration, but with no significant difference in the number of fluorescence photons between the group of 1.5 mg/ml and 2.0 mg/ml ( P=0.263, Bonferroni correction method). At 14 time points (0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 5.0, 6.0, 7.0, 8.0, 12, 24 h), there was no significant difference in the overall mean of fluorescence photons ( F=1.04, P=0.419), and the tissue with burn necrosis seen in tissue sections was highly consistent with the fluorescence imaging region. There was no obvious fluorescence residue in the heart, liver, kidney and brain sections. Conclusion:In superficial second-degree burn tissue, pHLIP-var7-FITC can accurately target and gather on the burn wound within 24 h, showing a clear boundary between burn tissue and normal tissue, which can assist clinical surgical debridement to determine the extent of injury.

Objective To investigate the interventional effect and mechanism of a novel ampe-lopsis hydrogel on dampness-heat accumulation syndrome of gouty arthritis.Methods A total of 90 patients with gouty arthritis who met the diagnostic criteria of western medicine and were differentiated as damp-heat accumulation syndrome of traditional Chinese medicine(TCM)were randomly divided into treatment group,control group and blank group,with 30 patients in each group.The blank group was treated with etoricoxib only,the control group was treated with etoricoxib combined with ampelop-sis hydrogel,and the treatment group was treated with etoricoxib combined with external application of ampelopsis hydrogel.The clinical efficacy,time to symptom improvement,safety,comfort,changes in syndrome scores of TCM,serum inflammatory factors[C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),erythrocyte sedimentation rate(ESR)],NF-κB signaling pathway-related pro-teins,Visual Analogue Scale(VAS)scores for pain,and joint mobility were compared among the three groups before and after treatment.Results The total effective rates in the treatment group and control group were 93.33％and 90.00％,respectively,which were higher than 70.00％in the blank group(P＜0.05).The time for improvement of pain,redness,tenderness,and limited joint mobility in the treatment group was shorter than that in the control group and blank group(P＜0.05).After 7 days of treatment,the TCM syndrome score in the treatment group was lower than that in the con-trol group and blank group,and the levels of serum CRP,TNF-α,and ESR and the expressions of NF-κB signaling pathway-related proteins P50 and P65 in the treatment group and control group were lower than those in the blank group(P＜0.05).After 7 days of treatment,the VAS score in the treatment group was lower than that in the control group and blank group,and the comfort score in the treatment group was higher than that in the control group(P＜0.05).There was no significant differ-ence in the incidence of adverse reactions among the three groups(P＞0.05).Conclusion The effect of ampelopsis hydrogel in treating gouty arthritis is better than that of ampelopsis paste,and its mechanism may be related to the regulation of the NF-κB pathway and inhibition of inflammatory fac-tor expression.The hydrogel is easy to use,hygienic,and comfortable,and is expected to become a safe,effective,and convenient external medicine for gouty arthritis.
