Objective To build rat models and observe changes of behavior and monoamine of PDD. Methods The rats were injected with 6-OHDA and accepted CUMS for the establishment of PDD model , so as to assess its behavior changes and detect brain tissue monoamine contents by ELISA. Results Significant behavioral and monoamine abnormalities can be observed in model rats. Behavioral and monoamine improvement can be observed after treated with Chaigan Jieyou. Conclusion The PDD model can be established by 6-OHDA and CUMS. Chaigan Jieyou decoction may reach therapeutic purposes by increasing monoamine contents.

Objective Comparing with traditional teaching methods of oral histopathology, to probe whether the interactive teaching system of the digital microscope can improve the teaching effi-ciency of experiment of oral histopathology courses. Methods The subjects were the 2010 grade students (40 students) and the 2011 grade students (38 students) majoring in stomatology of South Medical University, and they were evenly divided into 2 groups at random. In the first part of the ex-periment of Grade 2010, the teaching of traditional optical microscope was used in a group of experi-mental courses, and interactive teaching with digital microscope was used in the other group. In the second part of the experiment the two groups swapped the teaching method. While in the whole exper-iment of Grade 2011, traditional optical microscopes were adopted in one group, and in contrast, the interactive teaching system of the digital microscope was adopted in the other group. The P values of the 5 indexes were less than 0.05. After the courses, the 2010 grade students received the questionnaire survey and the 2011 grade students received the quiz about the experimental course, and then the evaluation results of the two groups were compared for t inspection, using SPSS software t test. Result The questionnaire results of Grade 2010 showed that the scores of digital microscope interactive group were higher than those of traditional teaching group in satisfaction with teaching , teacher-student interaction, classroom atmosphere active degree, learning interest, and the understanding of the teach-ing content. The experiment course content test results of Grade 2011 showed that the digital interactive group students averaged 46.26, while the average score of the traditional teaching group was 42.78%. The difference between the two groups had statistical significance, P=0.001. Conclusion Compared with the traditional teaching methods, the interactive teaching system of the digital microscope can enhance the academic grades, improve the teaching efficiency of experiment of oral histopathology courses, and elevate the teaching quality.

Objective To construct 2 recombinant plasmids carrying cassette chromosome recombinase C(ccrC)and ccrAB respectively and introduce the plasmids into methicillin-resistant Staphlococcus aureus(MRSA)strain 81/0432,and to observe the precise excision of Staphylococcal cassette chromosome mec(SCCmec)island from bacterial chromosome.Methods ccrC and ccrAB genes were amplified with chromosomal DNAs isolated from MRSA strains 81/0342 and N31S as PCR templates.We constructed recombinant plasmids pSR5C and pSR2AB by cloning ccrC and ccrAB genes into temperature-sensitive plasmid pYI3,after introducing them into MRSA strains 81/0432 and N315 by electroporation.PCR was performed to identify SCCmec excision from the bacterial chromosome.The transformants were serial passaged for 10 days,and then the drug resistance of these rransformants was detected by replica experiment.Results The fragment length of ccrC gene was 1.9 kb,smaller than the fragment length of ccrAB from N315.The recombinant plasmids of pSR5C and pSR2AB were successfully constructed.After these 2 recombinant plasmids were introduced into MRSA strain 81/0342,type-V SCCmec island was excised from the chromosome and formed a closed circular structure in the bacteria.However,type-Ⅱ SCCmec island could be excised only in N31S strain after the expression of pSR2AB.Replica experiment verified that transformed strains of 0342(pSR2AB),0342(pSR5C),and N315 (pSR2AB)were mostly susceptible to ceftizoxim or tobramycin after the excision of SCCmec island.Conclusion cciC could serve as a recombinase as ccrAB,which could mediate precise excision of SCCmec island from the chromosome of type-V MRSA strain.This study shows that type-V SCCmec island is widely disseminated between Staphylococcus aweus strains in community setting.

OBJECTIVE:To investigate general regularity and characteristics of adverse drug reactions/events(ADR/ADE)in-duced by Dezocine injection,and to provide reference for safe and rational drug use in clinic. METHODS:Retrieved from Jiangsu Province ADR Database during Jan. 2009-Aug. 2016,ADR/ADE induced by Dezocine injection was analyzed statistically in re-spects of patient's gender and age,usage and dosage,organs/systems involved in ADR,clinical manifestations and outcome. RE-SULTS:Among 1290 ADR/ADE induced by Dezocine injection,there were 40 cases of severe ADR/ADE(3.10%);medical insti-tutions were main reporting units (1276 cases,98.81%). In ADR/ADE cases,female was more male,with ratio of male to fe-male was 1:1.45. ADR/ADE mostly occurred in 45-65 age group(43.49%). Intravenous medication was main route of administra-tion (1137 cases,88.14%). Initial dose of 577 cases was excessive dose (50.75%). ADR/ADE mainly involved gastrointestinal system (54.99%),central and peripheral nervous system (24.72%) and systemic lesions (5.20%). Severe ADR/ADE manifested as anaphylactic shock,palpitation and dyspnea,etc. But anaphylactic shock was not mentioned in drug package inserts. 1283 ADR/ADE(99.46%)were cured or improved . CONCLUSIONS:It is necessary to strengthen drug safety reevaluation of Dezocine injec-tion after being on the market,improve drug package inserts and enhance patients education as so as to reduce and avoid the occur-rence of ADR/ADE.

BACKGROUND:Transient receptor potential channel C6 (TRPC6) is a new and important slit diaphragm-associated protein in podocytes involved in regulating glomerular filter function. Glomerular TRPC6 expression is closely associated with proteinuria in diabetic kidney disease. OBJECTIVE: To investigate the expression of canonical TRPC6 in mouse podocytes induced by high glucose, and to explore the possible mechanism of diabetic kidney disease. METHODS:Mouse podocyte cels were cultured and divided into normal glucose group (5.6 mmol/L D-glucose), normal control group (5.6 mmol/L D-glucose+25 mmol/L mannitol) and experimental groups which were in the environment of high glucose (30 mmol/L). The experimental groups included high glucose group, valsartan treatment groups (10-5 mol/L) and U73122 control group (10μmol/L U73122). After 48 hours, the expressions of mRNA and proteins of TRPC6, nephrin and angiotensin II (AngII) were detected respectively by real-time quantitative PCR and western blot analysis. RESULTS AND CONCLUSION:Compared with the normal control group, the expressions of mRNA and proteins of TRPC6 and angiotensin II were markedly elevated in the high glucose group (P < 0.01), while the expressions of mRNA and proteins of nephrin were decreased (P < 0.01). The mRNA and proteins of TRPC6 and angiotensin II expressions were significantly down-regulated by valsartan (P < 0.05,P < 0.01), while the mRNA and protein expressions of nephrin were effectively up-regulated (P < 0.05). Compared with the high glucose group, the expressions of mRNA and proteins of TRPC6 and angiotensin II were ameliorated in the U73122 control group. The expressions of mRNA and proteins of TRPC6, nephrin and angiotensin II had no statistical significance between the normal control group and normal glucose group (P > 0.05). Angiotensin II-TRPC6 signaling pathway may mediate high glucose-induced podocyte injury, meanwhile it provides a new theoretical basis for the treatment of diabetic kidney disease, by which the angiotensin receptor blockers can protect podocytes in diabetic kidney disease.
