OBJECTIVE:To provide references for the revision of pharmaceutical talents training plan in higher vocational colleges. METHODS:Selecting parts of freshmen,sophomores and junior students majoring in pharmacy in our hospital as subjects, questionnaires were conducted for the effect of hospital“pharmacy trusteeship”policy on their employment selection,and the results were statistically analyzed. RESULTS:Totally 190,390,320 questionnaires were received from junior students,sophomores and freshmen. The surveyed students knew less about“pharmacy trusteeship”policy,only a maximum by junior students of 35.79%(comparison of different grades P<0.05);while among the surveyed students from different career directions,the highest awareness rate about“pharmacy trusteeship”policy was from the students whose hospital pharmacy(41.30%-45.21%)(comparison of different career direction P>0.05). The career direction of hospital pharmacy had the highest proportion of surveyed students in each grade(38.42%-53.13%),especially the freshmen(comparison of different grades P<0.05,comparison of different career direction in a same grade P<0.05). But after knowing the policy,the surveyed students had the lowest recognition for the original career direction,especially the junior students(64.38%)(comparison of different career direction P<0.05). The surveyed freshmen and sophomores were firstly concerned the stability and then the welfare and income of the job,the surveyed junior students were firstly concerned the welfare and income and then authorized strength and the stability of the job. CONCLUSIONS:The pharmacy trusteeship policy has not yet been fully implemented,its effect on employment selection of higher vocational students majoring in pharmacy is relatively backward and the deeper effects have not been appeared completely.

Objective:
To explore the changes in the autophagy marker microtubule-associated protein 1 light chain 3 (LC3) and yeast autophagy-related gene 6 (Beclin1) in rat lungs exposed to free silica (SiO2) dust for different periods.
Methods:
A total of 72 male specific pathogen-free Wistar rats were randomly divided into solvent control group and SiO2 model group. The SiO2 model group received one-time non-exposed intratracheal instillation of suspension of SiO2 particles to establish a model of silicosis. The solvent control group received an equal amount of saline. Six rats each were sacrificed at 1, 7, 14, 21, 28, and 60 days after model establishment. The pathological changes and fibrosis of rat lungs at different time points were evaluated by H&E staining and Masson staining, respectively. Enzyme-linked immunosorbent assay (ELISA) was used to determine the levels of transforming growth factor-β (TGF-β) , interleukin-1 (IL-1) , and tumor necrosis factor-α (TNF-α) in lung tissue homogenate. Western blot was used to determine the relative expression levels of LC3 and Beclin1 in the lung tissue.
Results:
The results of H&E staining showed that the model group had continuous inflammation in the lung tissue from day 1 to day 60, and the inflammatory scores were significantly higher in the model group than in the control group (

Objective:To investigate the electrophysiological features of patients with anti-neurofascin 155 (NF155) IgG4 antibodies positive chronic inflammatory demyelinating polyradiculoneuropathy (CIDP).Methods:The electrophysiological data of 6 anti-NF155 IgG4 antibodies positive CIDP patients in Beijing Tiantan Hospital, Capital Medical University from September 2018 to May 2021 were retrospectively analyzed. Parameters studies included standard motor and sensory nerve conduction studies, electromyography (EMG) and F waves studies. Correlation analysis was made to explore the relationships between clinical indicators and electrophysiological data.Results:There was statistically significant difference in the motor nerve conduction study on abnormal rate of tibial nerve (χ 2=11.08, P=0.011). Motor nerve conduction abnormalities were presented in a majority of patients with decreased motor conduction velocity (MCV) and prolonged distal motor latency (DML). There was no statistically significant difference in the overall abnormal rate between lower limbs and upper limbs (30/32, 93.8% vs 22/22, 100.0%; χ 2=1.43, P=0.508), sensory nerve conduction and motor nerve conduction (52/54, 96.3% vs 42/42, 100.0%; χ 2=1.59, P=0.503). There was statistically significant difference in the overall abnormal rate in median nerve, ulnar nerve and sural nerve (χ 2=14.96, P=0.001;χ 2=10.00, P=0.007; χ 2=9.95, P=0.008),and absent sensory nerve action potential was the most common abnormality in sensory nerve conduction abnormalities. The abnormal rate of EMG was 9/14, which was constituted by upper limbs (4/8) and lower limbs (5/6), and the spontaneous activity accompanied with prolonged duration and increased amplitude of motor unit action potential was common. Significant negative correlations were established between disease duration and compound muscle action potential (CMAP) amplitude and negative area of ulnar nerve ( r=-0.84, P=0.036; r =-0.76, P=0.011), and the correlations between age and MCV of median nerve and ulnar nerve were also found ( r=0.89, P=0.019; r=0.95, P=0.003). The DML of median nerve was negatively correlated with CMAP amplitude ( r=-0.63, P=0.049). Moreover, the correlation analysis revealed associations of the F wave latency with the DML, CMAP amplitude and MCV of tibial nerve ( r= 0.90, P=0.039; r=-0.96, P=0.012; r=-0.96, P=0.010). Conclusions:The motor nerve and sensory nerve, the myelin sheath and axon of peripheral nerves in anti-NF155 IgG4 CIDP patients were largely affected. The CMAP amplitude and negative area of ulnar nerve might be of certain clinical value in reflecting the disease duration.The younger the patients, the more severe the demyelination degree of the upper limbs. The F wave latency of tibial nerve not only reflected the abnormal proximal conduction, but also the distal damage degree of myelin sheath and axon.

Objective:To investigate the association of peripheral axial lengths and retinal curvatures with refractive status.Methods:A cross-sectional study was conducted out.Two hundred and eighty-seven eyes of 287 consecutive children aged 6-15 years old who recieved eye examinations at Beijing Tongren Hospital from July to October 2021 were enrolled, including 154 males and 133 females.Uncorrected and best corrected visual acuity were tested with a standard logarithmic visual acuity chart.Spherical equivalent (SE) was measured via an auto refractometer after cycloplegia with tropicamide.The hyperopic, emmetropic and myopic groups were defined with a SE >+ 0.5 D, SE >-0.5 D to ≤+ 0.5 D and SE≤-0.5 D, respectively.Central and 30° peripheral eye lengths (nasal, temporal, superior, inferior) were obtained using the Lenstar LS900.Retinal coordinates were derived from partial coherence interferometry modeling and converted to retinal curvatures.According to the median horizontal peripheral eye length differences (absolute difference between nasal and temporal), participants were assigned to H1 group (absolute difference <0.35 mm) or H2 group (absolute difference ≥0.35 mm). According to the median vertical peripheral eye length differences (absolute difference between superior and inferior), participants were assigned to V1 group (absolute difference <0.32 mm) or V2 group (absolute difference ≥0.32 mm). Four groups of V1H1, V1H2, V2H1 and V2H2 were constructed according to the grouping methods in both directions above.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Beijing Tongren Hospital, Capital Medical University (No.TRECKY2021-162). Written informed consent was obtained from guardians of each subject prior to any medical examination.Results:The central axial length was 23.53(22.93, 24.10)mm.Peripheral eye lengths of temporal, nasal, superior and inferior were 22.75(22.11, 23.22)mm, 22.99(22.32, 23.45)mm, 23.24(22.58, 23.75)mm and 23.12(22.52, 23.56)mm, respectively.Temporal eye length was shorter than nasal, showing a statistically significant difference ( Z=-3.58, P<0.01). Compared with H2 group, H1 group had shorter central, nasal, superior and inferior eye lengths, showing statistically significant differences (all at P<0.05). Compared with V2 group, V1 group had shorter central, nasal and superior eye lengths, showing statistically significant differences (all at P<0.05). SE of H1 group was + 0.06 (-1.06, + 0.75) D, which was significantly greater than -0.32 (-1.64, + 0.56) D of H2 group ( Z=-2.10, P=0.04). SE of V1 group was + 0.13 (-0.81, + 0.80) D, which was significantly greater than -0.56 (-1.83, + 0.48) D of H2 group ( Z=-3.39, P<0.01). The myopia ratio of V1 group was 33.5% (58/173), which was significantly lower than 50.5% (53/105) of V2 group ( χ2=7.83, P<0.01). There was a significant overall difference in SE among VIH1, V1H2, V2H1 and V2H2 groups ( H=24.79, P<0.01). SE was greater in V1H1 group than V1H2, V2H1 and V2H2 groups (all at P<0.01). There was a significant difference in both horizontal and vertical retinal curvatures among different refractive groups ( H=22.34, 19.30; both at P<0.01). The retical curvature in both directions of hyperopic and emmetropic groups were significantly larger than those of myopic group (both at P<0.01). Conclusions:Peripheral eye lengths are asymmetric in school-aged children.Higher asymmetry is associated with myopic shifts.Myopic children have a steeper retina than the hyperopic and emmetropic children.

Transrectal contrast-enhanced ultrasound (CEUS) is an important examination for rectal tumors. The inhomogeneity of the CEUS images has important clinical significance. However, there is no objective method to evaluate this index. In this study, a method based on gray-level co-occurrence matrix (GLCM) is proposed to extract texture features of images and grade these images according the inhomogeneity. Specific processes include compressing the gray level of the image, calculating the texture statistics of gray level co-occurrence matrix, combining feature selection and principal component analysis (PCA) for dimensionality reduction, and training and validating quadratic discriminant analysis (QDA). After ten cross-validation, the overall accuracy rate of machine classification was 87.01%, and the accuracy of each level was as follows: Grade Ⅰ 52.94%, Grade Ⅱ 96.48% and Grade Ⅲ 92.35% respectively. The proposed method has high accuracy in judging grade Ⅱ and Ⅲ images, which can help to identify the grade of inhomogeneity of contrast-enhanced ultrasound images of rectal tumors, and may be used to assist clinical doctors in judging the grade of inhomogeneity of contrast-enhanced ultrasound of rectal tumors.
