Objective: To study the influence of different amino group introductions on the antiplatelet aggregation activities of pyridazinone derivatives. Methods: The target compounds were designed and synthesized by inletting different substitution amino groups using acetyl fragment as the connecting segment. Born method was used for preliminary pharmacological test in vitro. Results: Ten target compounds were designed and synthesized; 8 of them were reported firstly and all of them were confirmed by 1HNMR spectra. The results of preliminary pharmacological test showed that all the target compounds exhibited potent antiplatelet aggregation activity. The antiaggregation activities of compounds (6f), (6g), (6h) and (6j) were stong; compounds (6g) and (6j) showed a 5-time higher activity than 6-[4-(pyridin-4-yl-amino) phenyl]-4, 5-dihydro-3 (2H)-pyridazinone (MCI-154). Conclusion: Inletting different substitution amino groups can enhance the antiplatelet aggregation activity of the compounds.

Objective To apply the virtual reality training in clinical education of rehabilitation therapy. Methods 26 undergraduate students majored in rehabilitation therapy were randomly divided into 2 groups during clinical education of physiotherapy. The experimental group (n=14) received virtual reality training first, and then with routine teaching, while the control group (n=12) learnt with routine teaching only. Self-assessment and physiotherapy test were conducted after training. Results The experimental group reported more interested, initiative and positive in training than those of the control group. The experimental group achieved higher scores in practical tests than the control group (P<0.05), while no significant difference in the theoretical examination between the groups. Conclusion Application of virtual reality training may improve the teaching of physiotherapy.

Objective:To evaluate the relationship between breast reconstruction and postoperative complications by meta-analysis.Methods:Through a defined search strategy, related literature was collected in databases from PubMed, MEDLINE, EMBASE, Cochrane, CNKI, Wanfang Database and VIP Database, from January 1990 to November 2017. Data were extracted and each merged data was analyzed using RevMan 5.3 software. The postoperative complications between transverse rectus abdominis musculocutaneous-flap (TRAM) and deep inferior epigastric perforatorflap (DIEP), TRAM and latissimus dorsiflap (LDF), LDF and LDF+ prosthesis, LDF+ prosthesis and simple prosthesis implantation were compared.Results:Twenty-nine papers met inclusion criteria of our study. The Meta-analysis results showed that the risk of local flap necrosis, seroma, infection, fat liquefaction, abdominal wall hernia and abdominal bulging in TRAM group were higher than those in DIEP group, and the differences were significant. There was no significant difference in total flap necrosis, wound dehiscence, venous congestion between the two groups; the risk of total flap necrosis, wound dehiscence and infection in TRAM group were higher than those in LDF group, and the differences were significant. The risk of seroma in TRAM group was lower than that in LDF group, and the differences were significant. There was no significant difference in fat liquefaction between the two groups; there was no significant difference in the postoperative complications between LDF group and LDF+ prosthesis group; the risk of seroma in LDF+ prosthetic group was higher than that in prosthetic group, and the differences was significant. The risk of prosthetic capsular contracture and prosthesis displacement in LDF+ prosthetic group were lower than those in prosthetic group, and the differences were significant. There was no significant difference in prosthesis exposure and infection between the two groups.Conclusions:DIEP has most of the advantages of TRAM and fewer complications. It plays an important role in breast reconstruction in the future. We should make a choice of breast reconstruction methods according to the patient＇s conditions as far as possible in clinical practice.

Objective To systematically evaluate the clinical effectiveness and safety of Breviscapine injection combined with conventional therapy in the treatment of unstable angina pectoris (UAP).Methods The literature were systematicly retrieved about the randomized controlled trials (RCTs) of Breviscapine injection for UAP. The Cochrane Risk of Bias Assessment Table was used to evaluate the methodological quality of the RCTs and then the data were extracted and meta-analysed by RevMan 5.3 software.Results A total of 15 RCTs with 1202 participants were included. In the meta-analysis, the combination of Breviscapine injection and conventional therapy in the treatment of UAP can achieve better angina pectoris curative effect (Z=7.74,P<0.01), theRR(95% CI) was 1.23 (1.17,1.30), and the electrocardiogram curative effect (Z=6.26,P<0.01), the RR(95% CI) was 1.32(1.21, 1.44). Furthermore, Breviscapine injection can improve hemorheologic parameters. And there was no major or serious adverse drug event.Conclusions The Breviscapine injection combined with conventional therapy shows good therapeutic effect on UAP.

7% (OR=4.640,95%CI=1.064 to 20.239,P=0.041) were the high risk factors for myocardial ischemia in patients with type 2 diabetes.Conclusion Poor control of the 4 factors is the high risk factor for myocardial ischemia in patients with type 2 diabetes.Overall and effective control of such risk factors can decrease the incidence of myocardial ischemia and improve its treatment.

AIM: To discuss the safety of hands chopping phacoemulsification in patients with microcoria cataract.METHODS:Hands chopping phacoemulsification with intraocular lens implantation was used for the microcoria cataract of 30 patients ( 32 eyes ) . Their visual acuity, pupil, and complication were observed in postoperative 1d,1wk and 1mo.
RESULTS: Postoperative naked vision be or more than 0. 3 were in 27 eyes (84. 4%) at one day, be or more than 0. 3 were in 30 eyes (93. 8%) at one week, be or more than 0. 5 were in 28 eyes (87. 5%) at one month. All pupil returned to round or oval. No synechia happened in postoperative 1mo.
CONCLUSION:Hands chopping nucleus operation is safe and effective for uveitis combined with microcoria phacoemulsification.

ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female (P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow (P<0.01). Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different.

Tamoxifen and letrozole are two of the most effective pharmaceuticals mainly used in hormonal dependent) breast cancer therapy. A trace analytical method using ultra performance liquid chromatography/tandem mass spectrometry(UPLC-MS/MS) was developed to simultaneously detect these two drugs in both influent) and effluent of municipal sewage treatment plant. Sewage samples were passed through an Oasis HLB cartridge, then an amino solid phase extraction cartridge was connected with Oasis HLB cartridge. Target compounds) was firstly eluted with 6 mL methanol and then 3 mL methanol was used to elute the amino solid phase extraction cartridge, collected and pooled the elutants. After concentration, target compounds were separated) on a BEH C_(18)) column using a gradient elution profile with a mobile phase consisting of 0.1% formic acid aqueous) solution and acetonitrile and detected by an electro spray ionization tandem mass spectrometry with multiple reactions monitoring(MRM). Satisfactory linearity(R~2>0.997) was obtained over the range of 1.0-100 μg/L) and 0.1-100 μg/L for tamoxifen and letrozole, respectively, with limits of quantification(LOQ) of 1.0 and 0.1 ng/L. Mean recoveries of two target compounds(spiked in sewage samples at three concentration levels) ranged from 68.8% to 103.0%, with relative standard deviations(RSD) less than 15%. This method can be applied for the analysis of target drugs sewage samples.
