Selective salpingogram(SSG)and hysterosalpingography(HSG)have achieved fairly reliable diagnostic value. SSG and transcervical fallopian tube recanalization(T-FTR)possess rather credible therapeutic value,long-term effect and low risk. Recanalization rate and pregnancy rate,combining with the measurement of tubal perfusion pressures(TPP)and development of ultrasonic technology,can evaluate the therapeutic effect and safety more generally and objectively. Researches in the future should lay emphasis on developing non-radiologic technique,promoting diagnostic veracity,reducing side effects,and establishing randomly control trials together with consolidating the standardized evaluation criteria.(J Intervent Radiol,2007,16: 714-717)

Objective:To study the curative effect of hydrotalcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding. Methods:Seventy-six patients with gastric ulcer and bleeding in the stomach were selected and randomly divided into two groups. Thirty-two patients in the control group were treated with omeprazole alone while 44 patients in the observation group were treated with hydrotalcite combined with omeprazole. The therapeutic effects were compared between the two groups. Results:The total effective rate in the observation group was 100% while that was 87. 5% in the control group,and the difference between the two groups was statistically significant(P<0. 05). The comprehensive score of symptoms of the patients in the observation group was(4. 2 ± 1. 2)while that was(6. 2 ± 1. 4)in the control group,and the difference was significant(P<0. 01). The abdominal pain,abdominal distention and belching remission time in the observation group were slightly shorter than those in the control group(P<0. 05)and the time of hematemesis and hemafecia remission was significantly shorter than that in the control group(P<0. 05). After the 3-month treatment,the re-bleeding rate in the observation group was 6. 82%,which was slightly better than that in the control group,and the difference had no statistical significance(P<0. 05). The incidence of adverse reactions in the observation group was 9. 09% while that was 6. 25% in the control group,and there was no significant difference between the two groups(P>0. 05). Conclusion:Hydro-talcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding is effective and safe.

Objective:To study the protein leakage of mouse lens treated with hydrogen peroxide in vitro, and to identify and carry out bioinformatics analysis of the leaked proteins. Methods:Intact binocular lenses of 42 healthy male C57BL/6J mice were enucleated following sacrifice, and 28 lenses were arbitrarily combined as one sample, with 3 samples in total.Mouse lenses were cultured with medium containing 2 mmol/L hydrogen peroxide for 24 hours to establish a cataract model in vitro.Blank medium M-199 was taken as control sample.Supernatant was subjected to polyacrylamide gel electrophoresis (PAGE). The structure of the supernatant proteins was identified by liquid chromatography coupled with tandem mass spectrometry, and the high-abundant proteins were quantitatively analyzed by label-free quantitative mass spectrometry.The biological information of the identified proteins was analyzed by METASCAPE database.Content of cytokines in the supernatant was determined using the multiplex bead immunoassay system.This study protocol was approved by an Ethics Committee of The First Affiliated Hospital of Chongqing Medical University (No.2019-173), and the use and care of experimental animals complied with the ARVO statement. Results:After 24-hour culturing, the lenses became turbid, and the capsules were intact.The protein concentration in the supernatant was (3.73±0.59)μg/μl.PAGE analysis of the supernatant protein profile revealed that protein bands were below 35 000.A total of 675 proteins were identified with mass spectrometry.Sixteen crystallin proteins accounted for (86.1±0.8)% of the total protein abundance; the biological processes those proteins participated in mainly included cell-cell adhesion, cell transformation, oxidation-reduction, inhibition of apoptosis, and protein translocation; the molecular functions of those proteins mainly involved the activity of hydrolase, oxidoreductase, catalysis, translation initiation factor, and GTPase; the subcellular localization of proteins were mainly in cytoplasm, extracellular exosome, the nucleus, the plasma membrane, and the intercellular space.The results of an antibody-based multiplex bead immunoassay presented 9 cytokines in the supernatant, which included monocyte chemotactic protein-1 and transforming growth factor-β 2 highly expressed in intraocular fluid. Conclusions:There are protein leakages in lens treated with hydrogen peroxide in vitro, and it may have influences on metabolism and/or functions of other intraocular tissues.

In order to prevent the teaching reform of organ system curriculum from fall of teaching quality, the teaching effect of organ system curriculum and subject curriculum system in teaching the basic knowledge of pathophysiology was compared. In organ system curriculum teaching, there was no difference between the grades of students in Batch 2011 and Batch 2012 who conformed to the teaching principle of "gradual improvement" and those of the students taught with subject curriculum system. On the contrary, the students of Batch 2013 and Batch 2014 with insufficient curriculum content integration had a decreasing trend or a significant reduction in the teaching effect of organ system curriculum compared with that of subject curriculum system. After the supplementary for curriculum knowledge was made, the teaching effect of the organ system was significantly improved, which was better than that of the subject curriculum system. In conclusion, we have summarized and reflected on the effectiveness of the teaching reform of organ system curriculum, once again proved that basic medical teaching must also follow the inherent law of medical education, which is the teaching principle of "gradual improvement."

BACKGROUND:Animal models of osteoporosis play an important role in the research of the pathogenesis, occurrence and development of osteoporosis, as wel as in the clinical diagnosis, prevention and treatment of osteoporosis. OBJECTIVE: To summarize and discuss the establishment and research ideas of osteoporosis models, explore the current situation and advance of osteoporosis models, compare the advantages and disadvantages of various methods, and provide evidence for clinical investigation. METHODS: A computer-based online search was conducted in SinoMed, VIP, Wanfang and PubMed databases by using the key words of “animal model, osteoporosis” from January 1969 to October 2015. The language was limited to both Chinese and English. Relevant articles were screened according to inclusion and exclusion criteria. The documents about the methods of osteoporosis model preparation, method improvement as wel as their advantage and disadvantage were summarized. RESULTS AND CONCLUSION:A total of 576 articles were included. Among them, articles published earlier, duplicated, and similarly were excluded, and 53 articles were finaly included. Various animal models of osteoporosis may only focus on the certain causes, certain stage, some of the main symptoms and some pathophysiological changes of disease. Accordingly, appropriate modeling methods and experimental animals should be selected based on research objective. Rat undergoing castration is the most commonly used model in the modeling of osteoporosis. Among drug methods for constructing osteoporosis model, glucocorticoids is the most commonly used one. Disuse method and nutritional method have limitations, and always combined with castration and drug methods. The effects of gene transfer, gene mutation and brain-derived model deserve
