Objective To compare adaptive support ventilation (ASV) and pressure-controlled assist/control ventilation (PCMV) and evaluate the clinical effects of ASV. Methods 12 cases of acute respiratory failure patients induced by all causes were selected in the study. All patients with breathing independently underwent endotracheal intubation. The patterns of mechanical ventilation was PCMV-ASV-PCMV. the two settings of PCMV were uniformity. With ASV mode mechanical ventilation,we adjusted the percentage of minute ventilation (MV%) and ideal body weight (IBW) of patients,so as to reach the same minute ventilation volume of PCMV. We compared the blood gas,respiratory mechanics,work of breathing(WOB),airway occlusion pressure (P0.05). Compared with the first of PCMV,various indicators and blood gas of ASV had no significant difference,work of breathing (WOB),airway occlusion pressure (P=0.1) and inspiratory pressure time product (PTP) were significantly lower (P0.05). Conclusion ASV can get similar goals with conventional ventilation,and reduce patient′s effort and the central respiratory drive.

This paper proposed the idea of building the applied anatomical experiment and research platform for surgical postgraduates with professional degree,establishing double-tutorial system and applying applied anatomical teaching in basis course learning,clinical skill training and research capacity cultivating after analyzing the reasons of poor applied anatomical background of surgical postgraduates with professional degree.These ideas were intended to improve the cultivation quality.

Objective To compare the curative effect of percutaneous endoscopic lumbar discectomy (PELD) and microendoscopic discectomy (MED) in lumbar disc herniation.Methods A literature search was performed in PubMed, Web of Science, Embase, Wanfang, CNKI. Two authors reviewed all articles individually. The methodological quality of RCTs was assessed by the Cochrane risk of bias tool, and the quality of retrospective studies was evaluated by the modified Newcastle-Ottawa scale. The data was extracted by the Review Manager 5.30.Results A total of 19 articles were brought into this Meta-analysis. The outcomes were divided into primary outcomes and secondary outcomes. Excerpt for the short-term VAS score was lower in PELD group (P = 0.010), other index, including long-term VAS score (P = 0.120), ODI score (P = 0.260), complication (P = 0.100) and recurrence (P = 0.100), didn't had significant difference in two groups. The blood loss (P = 0.000), hospital stay (P = 0.000) and the length of incision (P = 0.000) were all superiority in PELD group. Whereas the operative time was shorter in MED group (P = 0.001).Conclusion PELD was a more minimally invasive and secure technique in lumbar disc herniation.

In this study, the "150-cavity", next to the H5N1 influenza virus neuraminidase activity site, has been used as the target to design and synthesize a structural analogue of chlorogenic acid, N-caffeoyl-GABA, using the flexible docking simulation. The docking study showed that the N-caffeoyl-GABA could be inserted into the "150-cavity" and combined with the Arg156 side chain by hydrogen bond. The best binding free energy of H5N1 NA-N-caffeoyl-GABA complex was -7.70 kcal mol(-1), equivalent that of the NA-oseltamivir. At the same time, using the H5N1 pseudotyping virus-based NA inhibitors screening model, we determined the inhibitory effect of oseltamivir, chlorogenic acid and N-caffeoyl-GABA on the NA. Compared with chlorogenic acid, N-caffeoyl-GABA significantly enhanced the inhibitory effect on NA, but less than oseltamivir. This study showed that the "150-cavity" could possibly be used as a new neuraminidase inhibitors target, and provided a path for the development of new neuraminidase inhibitors.

Starting from the characteristics of nervous system,breaking the traditional subject-centered teaching model,combining the nervous system-related basic and clinical courses,Chongqing Medical University has established a nervous-module organ-system integration curriculum since 2010.This new teaching model is introduced and practiced in 5-year outstanding medical class of Chongqing Medical University.The new integrated curriculum guides students to learn knowledge from points to surface,helps them to combine knowledge vertically and horizontally,and simplifies the duplicate teaching content,so as to promote students to develop coherent and innovative thinking mode.Integrated curriculum pattern is an inevitable trend in medical education reform.

Objective:To assess the effectiveness of Vision Therapy System 4 (VTS4) combined with traditional comprehensive training for ametropic amblyopia.Methods:A non-randomized controlled clinical study was performed.A total of 168 children aged 4-10 years with ametropic amblyopia were enrolled in The First Affiliated Hospital of Zhengzhou University from January 2018 to March 2021.The children were assigned to conventional comprehensive training combined with Vision Therapy System 4 group (conventional+ VTS4 group) and conventional group according to the preference of their guardian.Patients in conventional+ VTS4 group (84 children) received conventional comprehensive training combined VTS4 and patients in conventional group (84 children) were treated with conventional comprehensive training only, and the intervention was continuously used for over a year.Best corrected visual acuity (BCVA) of the patients converted to the logarithm of the minimum angle of resolution (LogMAR) units was examined by international standard visual acuity chart before and after therapy.Spherical equivalent of the patients was detected by optometry under cycloplegic conditions and skiascopy.Binocular and fusion vision was examined with a synoptiscope.The stereopsis was evaluated using Titmus Stereogram.The ocular axial length (AL) and mean keratometry (Km) were measured with the IOLMaster 500.The basic cure rate, BCVA, reconstruction rate of stereopsis, △SE, △AL and △Km following training were compared to evaluate the effectiveness and myopic shift between two groups.The patients in conventional+ VTS4 group were divided into 4-5 years old group and 6-10 years old group, with 42 cases in each group, and the basic cure rate, BCVA, reconstruction rate of stereopsis were compared to evaluate the therapeutic effect between the two groups.The basic cure was defined as acuity improved to ≥0.9, with reduced myopic diopter and stable therapy outcome over 6 months.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2021-KY-0891-002). Written informed consent was obtained from guardians prior to any medical examination.Results:The basic cure rate of conventional+ VTS4 group was 58.33%(49/84), which was significantly higher than 40.48%(34/84) of conventional group ( χ2=5.358, P=0.021). The BCVA in the conventional+ VTS4 group was better than that in conventional group, showing a statistically significant difference ( Z=-2.537, P=0.011). The recovery rates of binocular vision, fusion vision and stereo vision were 87.93%(51/58), 78.33%(47/60) and 70.77%(46/65) in conventional+ VTS4 group, which were higher than 65.57%(40/61), 57.81%(37/64) and 52.86%(37/70) in conventional group, respectively, with significant differences between them ( χ2=8.259, 5.968, 4.566; all at P<0.05). No significant difference was found in △SE, △AL, and △Km between conventional group and conventional+ VTS4 group (all at P>0.05). The basic cure rate was 69.05%(29/42) in the children aged 4-5 years group, which was higher than 47.62%(20/42) in 6-10 years group, respectively, showing a significant difference ( χ2=3.967, P=0.046). Both BCVA and the stereo vision recovery rate in the 4-5 years old group were better than those in the 6-10 years old group ( Z=-2.046, P=0.041; χ2=4.624, P=0.032). Conclusions:A combination therapy of VTS4 and conventional comprehensive training can improve the visual acuity and reconstruct the fusion and stereopsis of children with ametropic amblyopia, without causing additional myopic drift.

Anti-seizure medications (ASMs) are the main therapy for epilepsy.There are many kinds of ASMs with complex mechanism of action, so it is difficult for pharmacists to examine prescriptions.This paper put forward some suggestions on the indications, dosage forms/routes of administration, appropriateness of usage and dosage, combined medication and drug interaction, long-term prescription review, individual differences in pathophysiology of children, and drug selection when complicated with common epilepsy, for the reference of doctors and pharmacists.
