Objective:To explore the application and effect of flipped classroom in community clinical pharmacist training.Methods:Seventeen pharmacists trained in 2017-2018 were used as the control group and received traditional teaching mode. Fourteen pharmacists trained in 2019-2020 were used as the experimental group and received the flipped classroom teaching mode. Finally, the teaching effect was evaluated through the trainees' graduation examination results and satisfaction degree. The SPSS 25.0 was used to conduct the t test and chi-square test. Results:The task performance, prescription audit scores, clinical practice scores, and total scores in the experimental group were significantly higher than those in the control group ( P<0.05). However, there was no significant difference in usual performance between the two groups ( P>0.05). For satisfaction survey, the total score of Likert scale in the experimental group was (20.1±3.4), which was significantly higher than that in the control group (16.9±3.4). However, there was no significant difference in the satisfaction of clinical practice and teachers' level between the two groups ( P>0.05). Conclusion:Flipped classroom can improve the enthusiasm of community clinical pharmacist trainees to participate in learning, increase the level of the trainees' theoretical knowledge and professional practice, and is conducive to the cultivation of high-quality community clinical pharmacists.

Brain edema could be secondary to cerebral lesion caused by a variety of reasons, severe cases may result in brain herniation or even death. Accurate real-time monitoring of cerebral edema, rational application of dehydrating drugs, and timely treatment of cerebral edema were very important for patients. However, there were defects in the monitoring methods commonly used in clinical practice. Noninvasive brain-edema monitoring was a new method, which can quantify the degree of brain edema by electromagnetic disturbance and directly reflect the state of brain edema. This article reviews the application of noninvasive brain-edema monitoring in the treatment of in critically ill patients with traumatic brain injury.

Mitogen-activated protein kinase (MAPK) cascade system is one of the highly conserved signal systems in eukaryotic cells, which participates in the regulation of many biological processes. Under the stimulation of different signals (such as cytokines, neurotransmitters, and hormones), MAPK cascade activates downstream targets and controls a variety of cellular processes, including growth, immunity, inflammation, and stress response. In different cells, the effects of MAPK cascade on cells vary with the stimuli and the duration of stimulation. MAPK cascade induces Th differentiation and participates in T cell receptor signal pathway and B cell receptor signal pathway. MAPK cascades regulate various cellular activities related to the occurrence and development of cancer. A thorough and systematic understanding of the specific regulatory effects of MAPK cascade on various cellular processes will provide theoretical guidance for treating various diseases.

Objective:To study the regulatory effect of Wumen-Yiji powder on 5-hydroxytryptamine (5-HT) signal transduction system in intestine and hypothalamus of diarrhea irritable bowel syndrome (IBS-D) model rats. Methods:Sixty male SD rats were randomly divided into blank group (10 rats) and diarrhea irritable bowel syndrome group (50 rats). The diarrhea irritable bowel syndrome group formed the diarrhea irritable bowel syndrome model after 2 weeks of senna leaf gavage and restraint stress. They were randomly divided into model group, deshute group (1.5 mg/kg), low, medium and high dose group of Wumen-Yiji San (6, 12, 24 g/kg), with 10 rats in each group. After continuous administration for 2 weeks, the contents of 5-HT in serum, colon and hypothalamus were detected by ELISA; HE staining was used to observe the pathological changes of colon in each group. The protein and mRNA levels of tryptophan hydroxylase 1 (TPH-1), serotonin receptor 3 (5-HT3R), serotonin receptor 4 (5-HT4R), serotonin transporter (SERT) in colon and hypothalamus were detected by Western blot and RT-PCR, respectively. Results:Compared with the model group, the pathological morphology of colon in each treatment group was improved. Compared with the model group, the level of 5-HT in serum and colon significantly decreased ( P<0.05), and the level of 5-HT in hypothalamus of rats in the low, medium, high dose group of Wumen-Yiji San significantly increased ( P<0.05). The expression of TPH-1, 5-HT3R and 5-HT4R protein significantly decreased ( P<0.05), and the expression of SERT protein in the medium, high dose group of Wumen-Yiji San significantly increased ( P<0.05). The expression of TPH-1, 5-HT3R and 5-HT4R protein in hypothalamus increased ( P<0.05), and the expression of SERT protein in the high dose group of Wumen-Yiji San significantly decreased ( P<0.05). The mRNA levels of TPH-1 (4.778 ± 0.604, 3.278 ± 0.668, 1.670 ± 0.361 vs. 6.877 ± 0.148), 5-HT3R (3.807 ± 0.463, 2.697 ± 0.455, 1.132 ± 0.136 vs. 6.322 ± 0.778), 5-HT4R (4.521 ± 0.234, 2.801 ± 0.351, 1.331 ± 0.142 vs. 6.741 ± 0.293) in colon tissue of low, medium and high dose groups of Wumen-Yiji San decreased ( P<0.05). The level of 5-HT4R mRNA (0.616 ± 0.208, 0.726 ± 0.226 vs. 0.521 ± 0.062) increased ( P<0.05), and the level of SERT mRNA (1.563 ± 1.023 vs. 2.612 ± 1.035) in medium, high dose group of Wumen-Yiji San decreased ( P<0.05). Conclusion:The result showed that Wumen-Yiji San could regulate the expression of 5-HT signaling system relating proteins and mRNA in the colon and hypothalamus of IBS-D rats within a certain dose range, so as to improve the symptoms of IBS-D.

Objective:To explore the clinical and genetic features in a case of fatal familial insomnia (FFI).Methods:A case of 39 years old woman diagnosed as progressive supranuclear palsy based on the preliminary manifestation of imbalance and frequent falls was reported. The clinical features, imaging characteristics, electroencephalogram and polysomnography of the patient were analyzed, and the blood samples from the patient were collected for the sequencing of prion protein (PRNP) gene.Results:This patient is a middle-aged woman, whose clinical manifestations were posture instability and retropulsion, rapid progressive dementia and dysarthria, sleep-related dyspnea and laryngeal stridor, with autonomic symptoms of hypertension, sweating, tachycardia and irregular breathing. The results of PRNP gene sequencing revealed that the mutation of gene D178N/129M was detected.Conclusions:Laryngeal stridor plays an important role in the diagnosis of FFI. Posture instability and retropulsion are relatively rare in the FFI clinical symptom spectrum. Here, a case of FFI presenting with posture instability and retropulsion during the early stage with Met/Met at the polymorphic codon 129 is reported in China.

The fatality rate of traumatic cardiac arrest (TCA) is extremely high, and it is very different from that of non-traumatic cardiac arrest (NTCA) in resuscitation strategy. Only when the standard resuscitation process is combined with rapid treatment of various reversible causes can the mortality rate of patients be decreased. In this paper, the key factors leading to TCA are reviewed, such as hypovolemic shock, asphyxia, tension pneumothorax, pericardial tamponade, crush syndrome, craniocerebral injury, cerebral hernia, and the control measures are elaborated respectively, so as to provide references for clinical treatment of patients with severe trauma, and reduce TCA incidence and mortality.

Objective To explore the situation and question of standardized training of residents/graduate students in cardiac surgery by questionnaire survey. Methods From September 2010 to May 2012, 61 resident physicians/graduate students were chosen as research objects in Department of Cardiac Surgery, Peking University Third Hospital. A total of 61 questionnaires were sent out, with a recovery rate of 100%,and an effective rate of 95.1%.The contents of investigation included standardized training content design, standardized training management, the time and"environment" pressure, compliance training effect analysis,student opinion and others,a total of 14 options.EpiData 2.1a software was used to sort and record the data. SPSS 17.0 software was used for statistical analysis. The enumeration data were compared by chi square test.Results During the period of training,the most expected teaching method was"small lecture", accounting for 63.8%; The most difficult part of the process of cardiac surgery training was "postoperative care", accounting for 69%; 100% of the trainees thought that it would be helpful for future work through cardiac training;8.3% of the trainees thought the teachers of cardiac surgery teaching consciousness was not strong; resident weekend "in the hospital" was higher than the proportion of graduate students, and most graduate students chose weekend "in the experiment and research work", the difference was statistically significant (P<0.05). Conclusion Appropriate standardized training program should be combined with the students' background; Teaching team construction and clinical reasonable and effective clinical skills train-ing system is an important link to ensure the quality of teaching.The combination of residents' standardized training and postgraduate education of professional degree remains to be tracked and evaluated in a long time.The feedback from all aspects of the training should be paid more attention to,and the training details should be improved.

Sirt3 is a kind of nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases.Sirt3 is localized in mitochondria and has been involved in a wide range of mitochondrial biological functions, such as nutrient oxidation、ATP generation, reactive oxygen species (ROS) detoxification and mitochondrial homeostasis.Sirt3 plays an important role in the occurrence and development of cardiovascular diseases.Increased expression of Sirt3 gene has been associated with extended lifespan of humans.

[Summary] SIRT3 is a member of the silent information regulator 2 ( Sir2) family, located in the inner mitochondrial membrane, with a strong effect of deacetylation. SIRT3 not only modulates energy metabolism, cell apoptosis, tumor growth, anti-aging etc. , but also plays an important role in the field of cardiovascular diseases. In this review, we summarize recent findings related to SIRT3 with metabolic syndrome and cardiac hypertrophy, to provide a theoretical basis for the further study on the potential role of SIRT3 in cardiovascular diseases.
