ABSTRACT

Objective:To investigate the effect of the problem-based learning (PBL)-case-based learning (CBL) integrated teaching model in the training of clinical professional postgraduates on rotation in endocrinology.Methods:A total of 80 clinical professional postgraduates on rotation in endocrinology were randomly divided into experimental group (using PBL-CBL integrated teaching) and control group (using traditional teaching), with 40 students in each group, and the rotation period was 3 months. Professional examination scores were recorded for the two groups at the time of enrollment and graduation, and a questionnaire survey was performed to investigate their self-confidence, learning initiative, and interpersonal skills. SPSS 20.0 was used to perform the t-test and the chi-square test. Results:The two groups had similar conditions at baseline. After three months of rotation, the experimental group showed significant improvements in department examination scores, self-confidence, learning initiative, and interpersonal skills ( P<0.001). Conclusion:The PBL-CBL integrated teaching model has a better effect than traditional teaching and can help to improve the learning ability and performance of clinical professional postgraduates on rotation in endocrinology, and therefore, it holds promise for further application.

ABSTRACT

OBJECTIVE: To optimize the extraction technology of total vitamin E in Euryale ferox. METHODS: With the extraction amount of total vitamin E as reference index, using extraction time, extraction times, ultrasound power and comminution degree as reference factors, single fator test and Box-Behnken design-response surface methodology was used to optimize the extraction technology of total vitamin E from E. ferox. The validation tests were conducted for 3 times (the amounts of E. ferox were 2.0, 20.0, 40.0 g). RESULTS: The optimal extraction technology of vitamin E included that extraction time of 80 min, extraction times of 3 times, ultrasound power of 240 W, comminution degree of 80 mesh. In validation test, extraction rates of total vitamin E were 2.063, 2.103, 2.085 mg/g (RSD=2.6%, 1.5%, 1.3%, n=3), the relative errors of which to predicted value (2.092 mg/g) were 0.14%, 0.53% and 0.33%, respectively. CONCLUSIONS: The optimal extraction technology is reasonable, stable and feasible, and can be used for the extraction of total vitamin E in E. ferox.

ABSTRACT

Objective:To establish a GC method for the imultaneous determination of cinnamaldehyde, bornyl acetate, costunol-ide,dehydrocostus lactone,magnolol and honokiol in Dutong pills. Methods: The determination was performed on an HP-5 column (30 m ×0.32 mm,0.25 μm) with programmed temperature. The carrier gas was nitrogen with the flow rate of 2.0 ml·min-1. The injection volumn was 1 μl and the sample split ratio was 5:1. The inlet temperature was 280 ℃. The detector was a flame ionization detector with temperature at 300 ℃. Results:The linear ranges were 32.28-516.40 μg·ml-1for cinnamaldehyde(r=0.999 3), 27.06-433.00 μg·ml-1for bornyl acetate(r=0.999 2),25.65-410.40 μg·ml-1for costunolide(r=0.999 3),26.10-417.60 μg ·ml-1for dehydrocostus lactone(r=0.999 3),24.01-384.20 μg·ml-1for magnolol(r=0.999 0) and 18.32-293.10 μg·ml-1 for honokiol(r=0.999 4). The average recovery was 99.71%(RSD=0.67%),99.34%(RSD=1.18%),100.16%(RSD=0. 34%),100.40%(RSD=0.39%),99.32%(RSD=1.22%) and 99.58%(RSD=0.58%)(n=6),respectively.

ABSTRACT

Objective To investigate the role of Glial cells missing 2 (Gcm2) in pathogenesis of hypoparathyroidism by knocking out Gcm2 gene in adult mice.Methods Tamoxifen was used to induce conditional knock-out of Gcm2 gene in Gcm2E2fl/flCre-ER mice.Genotypes of knock-out mice were identified by PCR.The protein expression level of Gcm2 was measured by Western blotting.The serum calcium and phosphorus were detected by the calcium and phosphorus assay kits, and the serum parathyroid hormone (PTH) level was detected by ELISA.Parathyroid cell proliferation was tested by Ki-67 immunohistochemical assay.The mRNA expression levels of PTH and calcium sensing receptor (CaSR) were detected by Real-time PCR.Bone mineral density was detected by micro CT.Results Gcm2 gene of parathyroid was confirmed to be knocked out by PCR.Compared with wild type and solvent control groups, Gcm2 knock-out group showed markedly lower protein expression of Gcm2, notably higher serum phosphorus and lower serum calcium and PTH concentrations (all P<0.01).The proliferation of parathyroid cells in Gcm2 knock-out mice were significantly higher(both P<0.01).The mRNA levels of PTH and CaSR in parathyroid gland of the knock-out group were significantly reduced (all P<0.01).Bone mineral density was significantly higher in Gcm2 knock-out group (all P<0.01).Conclusion Knockout of Gcm2 can lead to hypoparathyroidism in adult mice, indicating that Gcm2 is probably a therapeutic target for hypoparathyroidism.

ABSTRACT

Objective To investigate the therapeutic effect of different methods of dressing on the wound after local debridement of dia-betic foot. Methods A total of 53 patients which underwent local debridement of diabetic foot were divided into control group and treatment group. Patients in control group were dressed on traditional measurement,while patients in the treatment group were dressed on the external medicinal wine for the diabetic foot basic on the traditional treatment. The local transcutaneous oxygen partial pressure,ulcer healing rate,av-erage healing time and the amputation rate were observed. Results The healing rate and percutaneous oxygen partial pressure of the treat-ment group were significantly increased than those in the control group (P<0. 05). The average healing time and amputation rate of the treat-ment group were significantly less than those in the control group (P<0. 05). Conclusion Dressing on external medicinal wine after local debridement of diabetic foot can improve the wound healing in the diabetic foot.

ABSTRACT

Animal medicine is an important part of traditional Chinese medicine with a long application history in China. Systematically understanding the history of the development of animal medicine is of great significance to scientific protection and rational use of animal medicine resources. It has certain guiding significance to protection of wild resources, exploitation of new substitutes, standardization and summary of artificial breeding, and artificial reproduction technology. Taking the development of bezoar as an example, this article expounded the following four aspects:the development history of animal medicine, national animal protection, technical development, and prospect forecast by summarizing the Chinese ancient medical books and consulting the relevant laws and regulations. The entire above are about to offer new ideas for the sustainable development, the development of new medicine resources, and the development of animal medicine related preparation product.

ABSTRACT

Objective To evaluate the treatment effect of negative pressure wound therapy ( NPWT) followed by ultrasonic debridement surgical system ( UDSS) in patients with diabetic foot. Methods Forty-seven diabetic foot ulcer patients( WagnerⅡ~Ⅲ) were divided into two groups,of which 26 patients treated with UDSS combined NPWT,and 21 patients treated with traditional surgical debridement combined NPWT were control group. Cure rate, markedly effective rate and adverse reaction and complication were compared between two groups. Results Compared with control group,the experiment group had higher markedly effective rate in the first week(P<0. 05),and healing rates were higher in the 2th,4th,6th,12th weeks (P<0. 05). There were no differences in the adverse reactions and complications between the two groups. Conclusion UDSS combined with NPWT can accelerate wound cure,may play an important role for the treatment of diabetic foot ulcer.
