Objective To observe the effects of exercise for weight loss summer camp on body composition, blood lipids, serum interleu-kin (IL)-6, tumor necrosis factor (TNF)-αand adiponectin of male obese adolescents. Methods 20 male obese adolescents of closed exer-cise for weight loss summer camp in 2014 were enrolled. They received aerobic exercise and diet program intervention for 4 weeks. Their body composition, blood lipid, serum IL-6, TNF-αand adiponectin were detected before and after exercise. Results Their body mass, lean body mass, body fat mass, percentage of body fat and body mass index (BMI) significantly decreased (P<0.001). And their levels of serum total cholesterol, triglyceride, low-density lipoprotein cholesterol, IL-6, TNF-αand adiponectin also decreased (P<0.05), while their adipo-nectin of per unit body fat significantly increased (P<0.01). Conclusion Exercise for weight loss summer camp can effectively bring down the obese of male obese adolescents, and improve their body composition, blood lipid metabolism and inflammation response.

Objective To investigate the efficacy of jet endotracheal tube (JET) designed by Wei (WEI JET) for tracheal intubation.Methods One hundred and two ASA Ⅰ-Ⅲ and Cormack & Lehane grade Ⅰ-Ⅳ patients of both sexes,aged 15-50 yr,weighing 40-99 kg,requiring tracheal intubation under general anesthesia,were randomly allocated into 2 groups (n =51 each):conventional tracheal tube group (group C) and WEI JET group (group WJ).Groups C and WJ were further divided into 2 subgroups according to Cormack & Lehane grade:difficult airway subgroup (n =16) and non-difficult airway subgroup (n =35).The patients were tracheal intubated with the common Kendall endotracheal tube in group C.Jet ventilation (driving pressure 100 kPa,frequency of ventilation 15 bpm,I∶ E =1∶2) was performed and the patients were simultaneously tracheal intubated with WEI JET of the same internal diameter in group WJ.PETCO2 was recorded immediately after mechanical ventilation.The success rate of tracheal intubation at first attempt and time spent were recorded.The complications were also recorded within 24 h after extubation.Results Compared with group C,the intubation time was significantly prolonged,and the success rate of tracheal intubation at first attempt was increased in patients with a difficult airway than that in the patients without difficult airways in group WJ (P ＜ 0.01).There was no significant difference in PETCO2 recorded immediately after mechanical ventilation,intubation time and the success rate of tracheal intubation at first attempt between the patients with a difficult airway and the ones without difficult airways in group WJ (P ＞ 0.05).PET CO2 recorded immediately after mechanical ventilation was significantly higher and the success rate of tracheal intubation at first attempt was lower in the patients with a difficult airway than in the patients without difficult airways in group C (P ＜ 0.01).No severe barotrauma such as pneumothorax,mediastinal emphysema and subcutaneous emphysema occurred in group WJ.There was no significant difference in the incidences of laryngospasm,sore throat,and flatulence between the two groups (P ＞ 0.05).Conclusion WEI JET can not only provide adequate ventilation safely and effectively in patients requiring tracheal intubation under general anesthesia,but also increase the probability of successful tracheal intubation in patients with a difficult airway.

Objective:To explore the clinical application of NanoString fluorescent barcode technology in the molecular subtyping of diffuse large B-cell lymphoma (DLBCL), and to analyze the correlation between the cell-of-origin subtype and prognosis of patients.Methods:The tumor tissue samples of 12 patients with DLBCL at the Third People's Hospital of Datong of Shanxi Province and 8 patients with DLBCL at Peking University, Health Science Center between January 2014 and December 2019 were collected. According to Hans algorithm, all patients were divided into 1 case of germinal center-derived B-cell (GCB) type and 19 cases of non-GCB type. NanoString platform was used to analyze the expression level differences of 15 genes-related to Lymph2Cx molecular subtyping of all samples at mRNA level. Hierarchical clustering was used to subgroup 20 DLBCL cases and to contrast the prognosis in different subgroups according to the subtyping.Results:NanoString fluorescent barcode technology was used to detect samples of 20 DLBCL cases and hierarchical clustering analysis was performed, and then subtyping results showed that 11 cases were GCB-like type and 9 cases were activated B cell (ABC)-like type. Based on Hans algorithm, 10 GCB-like cases were non-GCB type. According to the survival analysis, GCB-like group had a better overall survival compared with that in ABC-like group ( P=0.019). Conclusion:NanoString fluorescent barcode technology can be successfully applied to the cell-of-origin subtyping of DLBCL, and the molecular subtyping strategy can effectively predict the prognosis of patients.

Objective To study the effects of 5-HT1A receptor in hippocampal dentate gyrus on anxiety behavior of adult rats with Parkinson's disease (PD).Methods PD model in rats was constructed by using 6-hydroxydopamine (6-OHDA) to lesion the medial forebrain bundle (MFB).In lesioned rats and sham-operated rats,we examined the changes of the number of TFH-positive neurons in the SNc and VTA.We also examined how 5-HT1A receptor of hippocampal dentate gyrus (DG) modulates the anxiety-related behavior using open field test and elevated plus-maze test,and examined monoamine neurotransmitter changes in the striatum,medial prefrontal cortex (mPFC),amygdale and ventral hippocampus using reverse-phase high performance liquid chromatography with electrochemical detection.Results In 6-OHDA-lesioned rats,the SNc of the injected side showed a total loss of TH-ir neurons compared with the unlesioned side,and the number of TH-ir neurons in the VTA on the lesioned side decreased significantly to (34± 2)％.The locomotor activity in 6-OHDA-lesioned rats decreased compared with that in sham-operated rats.Unilaterally lesioning the MFB decreased the percentage of time spent in the center in the open-field test and percentages of open arm entries and open arm time of elevated plus maze test when compared with sham-operated rats.In the sham-operated rats,intra-DG injection of 8-OH-DPAT did not affect anxiety-like behavior.In 6-OHDA-lesioned rats,intra-DG injection of 8-OH-DPAT significantly increased the percentage of time spent in the center at a dose of 100 ng and 500 ng when compared with saline injection into the DG.Injection of WAY-100635 did not affect rats in the two groups.Unilateral 6-OHDA lesions of the MFB in rats significantly decreased DA levels in the ipsilateral striatum,mPFC,amygdale and ventral hippocampus compared with those in sham-operated rats,but had no effect on 5-HT or NA levels in those structures.Conclusion Unilateral 6-OHDA lesion of the MFB not only totally damaged DA neurons in SNc and partly damaged DA neurons in VTA,but also decreased DA level in the ipsilateral striatum,mPFC,amygdale and ventral hippocampus.Unilateral 6-OHDA lesion of the MFB induces anxiety-related behavior,and activation of 5-HT1A receptor in the hippocampal dentate gyrus has anxiolytic effect in the rat model of Parkinson's disease.

There are many problems existing in the basic teaching of traditional surgery, such as much more content, difficult operation, fewer learning hours, more passive acceptance while less active learning and so on. Flipped class based on the WeChat and team-based learning (TBL) is based on the on-line and off-line class. We can use WeChat group and subscription to issue relevant learning materials, learning tasks and test before class. Also, we can summarize and explain incisively by discussion after field operation in class, and answer and test in the way of WeChat discussion after class. Finally, the three-dimensional hybrid teaching will be condensed and sublimated by brand competition based on the basis of surgery, achieving knowledge transfer before class, knowledge internalization in class, knowledge consolida-tion after class and brand competition sublimation, in order to improve the teaching effect of surgical basis.
