Objective:To build the evaluation index system of traditiond Chinese medicine(TCM) service capacity in county-level TCM hospitals, for references to improve the TCM service capability in China.Methods:Based on the " structure-process-result" evaluation model, a preliminary screening index system for the evaluation of TCM service capacity in county-level TCM hospitals was established by analyzing relevant literature and policies; Two rounds of Delphi expert consultation were made to screen the evaluation indexes; The combination weighting method based on both expert scoring method and entropy weight method was used to determine the index weight.Results:The evaluation index system of TCM service capacity of county-level TCM hospitals was finally incorporated into 3 first-level indicators, 9 second-level indicators and 33 third-level indicators. The top five third-level indicators in terms of comprehensive weight were the person time of TCM preventive care in the year(12.02%), the person time of manual reduction diagnosis and treatment(9.03%), the person time of acupuncture and moxibustion(6.55%), the proportion of income from inpatient TCM services in medical income(5.87%) and the person time of massage(5.34%).Conclusions:From the perspective of the whole process of TCM service, the evaluation index system of TCM service capacity of county-level TCM hospitals reflectd the health service capacity of county-level TCM hospitals, highlighted the characteristics of TCM.

Objective:To investigate the effects and significance of acute and chronic trauma on brain degree centrality (DC) in patients with post-traumatic stress disorder (PTSD) who lost their only child at resting state.Methods:Retrospectively, the study enrolled a total of 51 parents with PTSD, including 35 PTSD parents whose children was lost in emergencies (acute bereaved PTSD group) and 16 PTSD parents whose children was lost of chronic causes such as diseases (chronic bereaved PTSD group). Fifty local adults were also included as healthy controls (HC group). The clinical administered PTSD scale(CAPS) was used to evaluate the severity of the subjects' clinical symptoms.Resting-state functional magnetic resonance imaging(fMRI) data of all subjects were collected and DC values were calculated.SPSS 22.0 software was used for statistical analysis.Covariance analysis was performed among three groups, while post hoc was performed between any two groups.What's more, correlation analyses were utilized between abnormal brain regions and the scores of CAPS.Results:Significant group effects were found in multiple regions, including the right inferior temporal gyrus (MNI: x, y, z=66, -27, -21), right temporal pole (MNI: x, y, z=54, 15, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15), bilateral medial superior frontal gyri (MNI: right x, y, z=6, 63, 12; left x, y, z=-3, 60, 18), left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with HC group, the DC of two patient groups increased in the right inferior temporal gyrus (MNI: acute x, y, z=63, -27, -21; chronic x, y, z=63, -21, -27); the DC of acute bereaved PTSD group decreased in the right temporal pole (MNI: x, y, z=45, 21, -15) and the right orbital inferior frontal gyrus (MNI: x, y, z=48, 24, -12), while the DC of chronic bereaved PTSD group decreased in the left inferior parietal angular gyrus (MNI: x, y, z=-45, -36, 51) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51). Compared with chronic bereaved PTSD group, the DC of acute bereaved PTSD group increased in the left inferior parietal angular gyrus (MNI: x, y, z=-33, -39, 42) and left postcentral gyrus (MNI: x, y, z=-45, -33, 51), while decreased in the right temporal pole (MNI: x, y, z=51, 12, -9), right orbital inferior frontal gyrus (MNI: x, y, z=42, 21, -15) and bilateral medial superior frontal gyri (MNI: left x, y, z=0, 57, 15; right x, y, z=3, 57, 15). In chronic bereaved PTSD group, the DC of the left postcentral gyrus was negatively correlated with C1 (avoid trauma-related thoughts, feelings) score in CAPS ( r=-0.606, P=0.028). In acute bereaved PTSD group, the DC of the left medial superior frontal gyrus was negatively correlated with D4 (high vigilance) score ( r=-0.416, P=0.020). Conclusion:There exist functional abnormalities of multiple brain regions in acute and chronic bereaved parents with PTSD.The high arousal symptoms of the former may be related with the abnormalities of prefrontal-amygdala neural circuit, while the latter show higher avoidance which may be associated with the dysfunction of somatosensory brain regions such as postcentral gyrus.

Objective:To investigate the effect of coping style on the gray matter volume in patients with post-traumatic stress disorder (PTSD) who lost their only child, and the mediating role of gray matter volume in evaluating the influence of coping style in clinical symptoms of these parents.Methods:A total of 57 parents with PTSD (PTSD group) and 162 parents without PTSD (non-PTSD group) who lost their only child from September 2016 to March 2017 were enrolled from Jiangsu Province, China. Brain MRI data at resting state were collected. Voxel-based multiple regression analysis was performed to confirm the brain areas in which coping style main effect, diagnosis main effect and their interaction had significant influences in gray matter volumes. Correlations among gray matter volume of brain areas related to coping style, coping style scale scores, and clinician-administered PTSD scale (CAPS) scores were analyzed. Structural equation modeling was used to analyze the mediating role of gray matter volume in the influence of coping style in clinical symptoms of parents lost their only child.Results:(1) The coping style main effect did not significantly influence the gray matter volume in all subjects, and the diagnosis main effect had significant influence in gray matter volume in the right lingual gyrus; their interaction had significant influence in gray matter volume in the right peritalar fissure cortex and lingual gyrus. The positive coping style in the PTSD group had significant influence in the gray matter volumes of the right peritalar fissure cortex and lingual gyrus. (2) In the PTSD group, the scores of positive coping style were positively correlated with the gray matter volumes of the right talus fissure and the lingual gyrus ( P<0.05); the scores of positive coping style, and the gray matter volumes of the right talus fissure and the lingual gyrus were negatively correlated with scores of CAPS-C 5 and CAPS-C ( P<0.05). (3) In the PTSD group, positive coping style can positively predict the gray matter volumes of the right talus fissure and the lingual gyrus; the gray matter volumes of the right talus fissure and the lingual gyrus can negatively predict the avoidance-related symptoms. Conclusion:Positive coping style has influence in the gray matter volumes of the right talar fissure and lingual gyrus of PTSD patients lost their only child; and less positive coping style may affect the brain areas related to visual information processing, thus aggravating avoidance-related symptoms of PTSD patients.

AIM:To investigate the relationship between the number of dopaminergic neurons and the locomo-tor behavior of animals,and to provide a reference basis for the modeling of mice with different stages of Parkinson disease(PD)and different types of locomotor deficits based on 6-hydroxydopamine(6-OHDA)injection.METHODS:We in-duced lesions in the substantia nigra pars compacta(SNc)by administering various doses of 6-OHDA(3 g/L,6 g/L,and 12 g/L)to create PD mouse models with differing degrees of injury,thereby mimicking the various stages of PD progression observed in patients(early,moderate and advanced stages).On the 14th day post-surgery,we evaluated the behavioral deficits of the mouse models using the rotarod test,pole test,beam traversal test,open field test,and gait analysis.Fur-thermore,the quantification of tyrosine hydroxylase(TH)-positive neurons within the SNc and TH-stained dopaminergic terminals in the corpus striatum caudate-putamen(CPu)was conducted utilizing immunofluorescence staining techniques to assess brain tissue damage.RESULTS:Compared to the control group,the number of dopaminergic neurons in the SNc was significantly reduced in both the high-dose group(P<0.05)and the medium-dose group(P<0.05)following 6-OHDA injection,demonstrating a dose-dependent effect(Spearman correlation,P<0.01).Similarly,the dopaminergic terminals in the CPu were significantly diminished in the high-dose group(P<0.01)and the medium-dose group(P<0.05).Behavioral tests revealed that mice in the high-dose group exhibited severe impairments in motor coordination and hindlimb balance,as evidenced by reduced rotarod test times,gait abnormalities,and asymmetrical forelimb use in the cylinder test.In contrast,mice in the medium-and low-dose groups displayed only mild declines in limb coordination,while their autonomous motor abilities and gait indices remained largely unaffected.CONCLUSION:The results reveal a dose-dependent effect on dopamine neuron damage,with higher doses causing the severest damage.Unexpectedly,signifi-cant locomotion impairments were only manifested in the high-dose group.This suggests that a mouse model induced by higher 6-OHDA dose is effective for studying PD and associated dyskinesia.Conversely,animal models with low to medi-um doses can be useful for exploring the early stages of PD locomotion symptoms.
