College English education in TCM universities should set up its own unique education system characterized by the TCM characteristics, manipulability and generalizability. Here the Beijing University of Chinese Medicine was taken as an example to discuss the necessity, theoretical basis, specific methods and preliminary achievements of the application ability-oriented college English education reform in the past six years that serves students' learning needs and career development as well as the university's talents cultivation.

Objective:To investigate the expressions of Th 1-Th2-Th17 cytokines in the coxsackievirus B 3-induced mice chronic viral myocarditis(VMC).Methods:BALB/c mice were intraperitoneally(i.p) infected with increased CVB3 for establishing chronic VMC models.Control mice were treated with phosphate-buffered saline(PBS)i.p.Cardiac tissues were obtained 8 weeks after CVB3 in-jection,myocardial histopathologic changes were observed by HE and Masson staining .Th1-Th2-Th17 cytokines in plasma were detected by protein array technology , and their cardiac mRNA expressions were measured by RT-PCR.Results: Compared with the control group,levels of IL-2,IL-5,IL-10,IL-13,IL-17,IL-6,IL-22,IL-21 and TGF-βobviously increased in chronic VMC group (P all<0.05). Conclusion:The imbalance of Th1-Th2-Th17 cytokines may play an important roles in the pathogenesis of chronic VMC .

Objective To study the effect of the toothpaste containing FE enzyme on oral care to for critically ill patients with stroke. Methods Sixty cases of critically ill stroke patients were randomly divided into the experiment group and the control group with 30 cases in each group.The toothpaste containing FE enzyme was used in experiment group for oral care,and the routine oral care was used in the control group.The two groups were compared in terms of the oral cleaning effect,dental plaque and costs for the oral care.Results The incidences of bad breath,oral uncleanness and oral infection were significantly lower than those of the control group(P<0.01 or P<0.05). The dental plaque index after oral care was significantly lower in the experiment group than that in the control group(P<0.001).The cost in the experiment group was significantly lower than that in the control group(P<0.01).Conclusion Oral care using toothpaste containing FE enzymecan not only achieve an effective oral cleaning purpose,but also reduce the cost of oral care.

Objective:To analyze the effect of insulin aspart on the islet cell secretion function, ultrasound imaging indicators and maternal and infant outcome in patients with gestational diabetes mellitus (GDM).Methods:The clinical data of 120 patients with GDM in Beijing Obstetrics and Gynecology Hospital Affiliated to Capital Medical University from February 2017 to July 2019 were retrospectively analyzed. Among them, 60 cases were treated with insulin aspart (observation group) and 60 cases were treated with biosynthetic human insulin (control group). The efficacy indexes, ultrasound imaging indexes and maternal and infant outcome were compared.Results:The 2 h postprandial blood glucose (2 h PBG) after breakfast on the third and fifth day of treatment in observation group was significantly lower than that in control group: (6.85 ± 0.87) mmol/L vs. (7.47 ± 1.35) mmol/L and (6.24 ± 0.59) mmol/L vs. (6.60 ± 0.87) mmol/L, and there was statistical difference ( P<0.01); there was no statistical difference in 2 h PBG after breakfast on the first day of treatment and after lunch and dinner on the first, third and fifth day of treatment between 2 groups ( P>0.05). The homeostasis model assessment-insulin resistance index (HOMA-IR) after treatment in observation group was significantly lower than that in control group (2.57 ± 0.25 vs. 3.00 ± 0.35), the homeostasis model assessment- β cell function index (HOMA-β) was significantly higher than that in control group (72.45 ± 12.33 vs. 63.66 ± 10.72), and there were statistical differences ( P<0.01). There were no statistical differences in pre-lunch blood glucose, pre-lunch initial insulin amount, pre-lunch final insulin amount and blood glucose target time between 2 groups ( P>0.05); the incidence of pre-meal hypoglycemia in observation group was significantly lower than that in control group: 8.33% (5/60) vs. 23.33% (14/60), and there was statistical difference ( P<0.05). The umbilical artery and renal artery resistance index (RI), maximum systolic blood flow velocity and end-diastolic blood flow velocity ratio (S/D) after treatment in observation group were significantly lower than those in control group (RI: 0.49 ± 0.16 vs. 0.59 ± 0.15 and 0.69 ± 0.17 vs. 0.76 ± 0.12; S/D: 2.09 ± 0.22 vs. 2.38 ± 0.26 and 5.17 ± 0.45 vs. 5.77 ± 0.63), and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in gestational age, delivery mode, neonatal body weight and the incidences of macrosomia, neonatal hypoglycemia and neonatal referral between 2 groups ( P>0.05). Conclusions:Insulin aspart can significantly improve the islet cell secretion function and ultrasound imaging indexes in the treatment of GDM, and can reduce the risk of pre-meal hypoglycemia, but the effect on maternal and infant outcome remains to be explored.

Objective To study the clinical pathological features, treatment and prognosis of umbilical metastases of colorectal carcinoma. Methods From January 2000 to September 2010, 10 umbilical metastases of colorectal carcinoma cases were admitted. The clinical features were reviewed. Results Four radical resection of colon cancer and resection of the umbilical plexus metastases cases with chemotherapeutic intraperitoneal perfusion lived 9,11,14 and 18 months respectively, 1 ileum-transverse colon anastomosis case with chemotherapeutic intraperitoneal perfusion lived six months, 2 patients with systemic widely transfer and umbilical transfer with pure venous chemotherapy lived 3, 3.5 months respectively, 3 colon intra-operative cases with venous chemotherapy lived 5 ,5. 5 and 7 months respectively. Conclusion Surgical resection of the primary focal and periumbilical metastases can prolong survival time with adjunctive therapy.

AIM: To evaluate the relationship between the medial rectus cells counts in concomitant exotropia and surgical results. METHODS: A total of 32 pieces of medial rectus muscle were collected for HE staining in this study, of which 18 pieces were from patients with concomitant exotropia and 14 pieces were from healthy individuals. A method of strabismus score was used to assess the operative effect.RESULTS: The difference of strabismus score before and after the operation in the intermittent exotropia group was significantly higher than that in constant exotropic group (P<0.01). Under light microscope, the loosen muscle fibers and the increased stromal components in the cross sectional area of medial rectus were observed in strabismic group. The muscle cells counts was obviously lower in strabismic group than in control group (P<0.01), which was related to the difference of strabismus score before and after the operation (P<0.05).CONCLUSION: The decreased medial rectus cells counts induce concomitant exotropia directly. It is the crucial causes of the bad surgical results.

Purpose Polypoid endometriosis is an uncommon and distinctive variant of endometriosis, and its detailed histopathological features have been investigated and analysed. Methods A retrospective analysis was performed in 10 cases with polypoid endometrio-sis by comparing clinical data, histopathologic and immunohistochemical changes. Results The patients were 27 to 54 years ( mean 39. 4 years) of age. The most common clinical presentations were a pelvic mass. The intraoperative findings suggested a neoplasm. Sites of involvement in order of frequency included ovary, uterine serosa and cervix. Polypoid, pink, gray or tan masses ranged up to 9 cm in maximal dimension. On microscopic examination, the polypoid masses were composed of an admixture of endometriotic glands and stroma. Most commonly glandular architectural patterns were simple hyperplasia. Tubal epithelial metaplasia was common. The stroma was fibrous, resembling to some extent the stroma of the endometrial polyp and atypical stromal cells can be seen. Nine cases were associated with usual endometriosis. Follow-up data in nine patients indicated that all of patients were alive without evidence of re-sidual disease. The main lesion in the differential diagnosis is a mullerian adenosarcoma. Conclusion Polypoid endometriosis is a rare manifestation of endometriosis, and probably is overgrowth of local ectopic endometrium based on endometriosis. Understanding of such lesions is avoided misdiagnosing for other benign or malignant tumors on clincal, intraoperative or pathologic assesment, and influ-ences the clinical treatment.
