OBJECTIVE To understand the development status and existing problems of traditional Chinese medicine（TCM） pharmacists in public TCM hospitals in China， aiming to provide suggestions for the competent departments to formulate management policies for TCM pharmacists and promote the healthy development of TCM. METHODS The data on the number and professional titles of TCM pharmacists in public TCM hospitals in China from 2019 to 2023 were collected. Descriptive analysis was employed to analyze the number， distribution and professional titles of TCM pharmacists in public TCM hospitals across the country， and to measure the quantity shortfalls of the number of TCM pharmacists in these hospitals. RESULTS From 2019 to 2023， the number of TCM pharmacists in public TCM hospitals in China grew slowly， with an average annual growth rate of 2.56%. However， the proportion of TCM pharmacists to the total number of pharmacists in public TCM hospitals gradually decreased， with an average annual growth rate of －0.65%. In terms of hospital grades， the number of TCM pharmacists in tertiary public TCM hospitals showed positive growth， while those in secondary and primary public TCM hospitals showed negative growth. In terms of hospital types， the average annual growth rate of TCM pharmacists in TCM hospitals was 2.22%， in integrated Chinese and Western medicine hospitals it was 7.97%， and in ethnic minority medicine hospitals it was 2.74%. The development of TCM pharmacists in different provinces was uneven. The annual growth rate of TCM pharmacists in Guizhou exceeded 10%， while the growth rate in Hunan and Heilongjiang was negative. In 2023， the number of TCM pharmacists per thousand population in public TCM hospitals was 0.03， indicating a relatively low staffing level. The professional titles of TCM pharmacists in public TCM hospitals were mainly primary and E-mail：601907549@qq.com intermediate， with a total of 67.33%. According to the calculation that the proportion of TCM pharmacists to pharmacists was not less than 60%， public TCM hospitals and hospitals of integrated TCM and Western medicine should be reconfigured with TCM pharmacists 6 212 and 1 288 people， respectively. CONCLUSIONS The number of TCM pharmacists in public TCM hospitals is growing slowly， with insufficient staffing levels， relatively low professional titles， and uneven distribution and development across provinces. It is suggested that relevant competent departments strengthen policy guidance， increase the attention given by the state level to TCM pharmacists， strengthen the construction of the talent team for TCM pharmacists， improve the quality and optimize the allocation of TCM pharmacist talents in order to promote the high-quality development of TCM services.

Objective: To investigate the difference in behavioral characteristics among different phenotypes of attention deficit hyperactivity disorder (ADHD) using amplitude of low-frequency fluctuation (ALFF), so as to provide insights into clinical differentiation of behavioral characteristics among different phenotypes of ADHD. Methods: The children with ADHD admitted to The Affiliated Hospital of Hangzhou Normal University were enrolled and classified into the inattentive type (ADHD-I), hyperactive/impulsive type (ADHD-HI) and combined type (ADHD-C). The reaction time (RT) was measured using integrated visual and auditory continuous performance test, and the mean (RT-mean) and standard deviation of RT (RT-SD) were estimated. In addition, the ALFF was calculated at 0.010 to 0.027, 0.027 to 0.073, 0.073 to 0.167 Hz, and the difference of ALFF was compared among children with different types of ADHD. Results: A total of 107 children with ADHD were enrolled, including 95 boys and 12 girls, with a mean age of (8.89±1.93) years. There were 69 children with ADHD-I, 8 children with ADHD-HI and 30 children with ADHD-C. The RT-SD was significantly higher among children with ADHD-C than among children with ADHD-I [(126.003±51.619) ms vs. (97.720±45.302) ms; P=0.007]; however, there was no significant difference in RT-mean among children with various ADHD phenotypes (F=1.386, P=0.255). There was an interaction between frequency and ADHD phenotypes (F=2.754, P=0.032), and the ALFF was significantly higher among children with ADHD-C than among children with ADHD-I at 0.010 to 0.027 [(5 590.567±231.595) ms vs. (4 694.001±154.397) ms; P=0.002] and 0.073 to 0.167 Hz [(4 312.609±174.709) ms vs. (3 690.805±116.473) ms; P=0.005]. Conclusions The ALFF varies in ADHD phenotypes, and there is a frequency-specific difference.

Objective:To explore the evolution of imaging findings on dynamic chest high resolution CT（HRCT） in patients with mild COVID-19.Methods:The data of epidemiology, clinical data and continuous dynamic chest high-resolution CT images of the patients with mild COVID-19 were analyzed retrospectively. Twenty-five patients (including 24 common type and 1 mild) were enrolled in the group, including 14 males and 11 females, with age of （42±12） years and hospital stay of （19±5） days. The basic images and dynamic images of HRCT were analyzed and compared by the radiologists.Results:The clinical manifestations were fever (22 cases), cough (18 cases), expectoration (8 cases), pharyngeal pain (6 cases). Most laboratory tests lacked specificity. There were no significant abnormalities on chest CT of one mild patient. HRCT findings of the common type were as follows: (1) the distribution of the lesions: most of the multiple lesions involved both lungs (19 cases), with average of 3 (3±1) lobes, located in the peripheral pulmonary zone near the pleura (22 cases); (2) the morphology and density of the lesions: most of the lesions were ground glass density foci (22 cases), which were patchy and massive (18 cases), nodular (10 cases) and arc broadband (7 cases); with the development of the disease, the density of some lesions increased with localized pulmonary consolidation (10 cases), accompanied by air bronchus sign (5 cases) and halo sign (5 cases). Dynamic changes of HRCT images in the chest: the positive manifestations were found on the 5th (5, 6) day after the onset of the disease, the progressive time of CT lesions was 5 (5, 7) days, the peak time of CT lesions was 11 (10, 13) days, and the turning time of CT lesions was 9 (8, 11) days.Conclusions:Dynamic chest HRCT can monitor the basic evolution process of the disease in patients with mild COVID-19, and provide a more intuitive basis for clinical early diagnosis and treatment.

The contractile force of hepatic stellate cells plays a very important role in liver damage, hepatitis and fibrosis. In this paper, a method based on polydimethylsiloxane (PDMS) thin micropillar arrays is proposed to measure the contractile force of human hepatic stellate cell line LX-2, which enables dynamic measurement of the subcellular distribution of force magnitude and direction. First, thin micropillar arrays on glass bottom dish were fabricated using two-step casting process in order to meet the working distance requirement of 100× objective lens. After hydrophilic treatment and protein imprint, cells were seeded on the micropillar arrays. LX-2 cells, which were quiesced by growth in serum-free medium, were activated by adding fetal bovine serum (FBS). The deflections of the micropillars were achieved by image processing technique, and then the contractile force of cells exerted on the micropillars was calculated according to mechanical simulation results, and was analyzed under both quiescent and activated conditions. The experimental results show that the average traction force of quiescent cells is about 20 nN, while the contractile force of activated cells increased to 110 nN upon adding FBS. This method can quantify the contractile force of LX-2 cell on subcellular scale in both quiescent and activated states, which may benefit pathology study and drug screen for chronic liver diseases resulted from liver fibrosis.

Objective To investigate the effects of citicoline combined with rehabilitative training on motor function after focal cerebral ischemia. Methods One hundred and twenty male adult Sprague-Dawley rats ( 3 months old) were subjected to left middle cerebral artery occlusion (MCAO) by suturing. Ninety-six of them were randomly divided into four groups of 24: a control group, a drug group, a rehabilitative training group, and a drug combined with rehabilitative training group. The rats in the control group did not receive any treatment. Three days after reperfusion, those in the drug group received 500 mg/kg of citicoline daily; those in the rehabilitative training group received motor training including balancing, grasping, rotating and walking exercises; those in the combined group received both citicoline and the motor training program. Behavioral tests were administered at the 7th, 14th and 21st days after MCAO. At the same time points, immunohistochemistry was used to detect calcium-binding protein S100 and β-tubulin expression in the peri-ischemia region of the cortex. Results ①As compared with the control group, the drug group at the 7th, 14th and 21st day after MCAO and the other two groups at the 7th day after MCAO showed no significant difference in average behavior scores. But at the 14th and 21st day the rehabilitative training group as well as the drug combined with rehabilitative training group had average behavior scores significantly superior to those of the control group, especially in the drug combined with rehabilitative training group. ②As compared with the control group, the expression of S100 and β-tubulin in the drug and rehabilitative training groups at the 7th day after MCAO showed no significant difference. In the drug combined with rehabilitative training group the average score was significantly higher than in the other groups at the 7th day after MCAO. All the other groups had average scores significantly higher than that of the controls at the 14th and 21st day after MCAO, especially the drug combined with rehabilitative training group. Conclusions Citicoline combined with rehabilitative training can significantly improve motor function recovery in rats. The effect of the combined modalities was more obvious, and the functional enhancement might be partially attributable to the up-regulation of S100 and β-tubulin in the cortex.
