Objective To investigate and analyze the resources and application frequency of radiological diagnosis and treatment in Jinan City in 2023 and provide a basis for the rational application of radiological diagnosis and treatment resources and strengthening radiological health protection management. Methods The health administrative department issued a work plan. A general survey was conducted on radiological diagnosis and treatment institutions (excluding dental clinics) in Jinan City using a questionnaire. The survey covered the basic information of the radiological diagnosis and treatment institutions, the distribution of the radiological diagnosis and treatment equipment, the number of radiological workers, and the frequency of radiological diagnosis and treatment. Results There were 301 radiological diagnosis and treatment institutions in Jinan City, with 1603 sets of radiological diagnosis and treatment equipment and 5789 radiological workers. These institutions included 41 (13.62%) tertiary hospitals, 57 (18.94%) secondary hospitals, 110 (36.54%) primary hospitals, and 93 (30.90%) ungraded hospitals. Tertiary hospitals had the highest proportions of radiological diagnosis and treatment equipment and workers, accounting for 49.53% and 69.10% of the total, respectively. The frequencies of radiological diagnosis and treatment were 868.86 X-ray diagnostic imaging examinations per 1000 population, 5.07 radiotherapies per 1000 population, 14.19 interventional diagnostic and therapeutic procedures per 1000 population, 7.36 nuclear medical diagnostic procedures per 1000 population, and 0.56 nuclear medical therapeutic procedures per 1000 population. The frequency of CT diagnosis was the highest, reaching 407.76 procedures per 1000 population. Conclusion The radiological diagnosis and treatment resources and activities in Jinan City were mainly concentrated in tertiary hospitals, with unbalanced distribution among hospitals of different grades. It is necessary to apply various medical radiations correctly and reasonably and strengthen radiation protection to reduce the frequency of radiation and the collective effective dose.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

Background: and Purpose CGG repeat expansion in the 5' untranslated region (5'UTR) of the Notch 2 N-terminal-like C gene (NOTCH2NLC) has been associated with neuronal intranuclear inclusion disease (NIID) and oculopharyngodistal myopathy type 3 (OPDM3). Few OPDM3 patients have been reported. This report describes two OPDM3 patients with novel imaging findings who presented the typical features of NIID, and reviews all OPDM3 cases available in the literature. Methods: The available clinical, imaging, and pathological information was reviewed and investigated. CGG repeat expansion in the 5'UTR of NOTCH2NLC was tested using the repeatprimed polymerase chain reaction (PCR), followed by the fluorescence amplicon-length PCR to determine the number of CGG repeats. Results: Our two OPDM3 patients and most patients reported in the literature developed the typical clinical characteristics of NIID, including leukoencephalopathy, peripheral neuropathy, cognitive deterioration, pigmentary retinopathy, ataxia, tremor, acute encephalitis-like episodes, pigmentary retinopathy, miosis, and sensorineural hearing loss. In addition to typical imaging findings of NIID, our two patients exhibited diffusion weighted imaging (DWI) hyperintensities in the middle cerebellar peduncles, which have not been described previously. Muscle biopsies revealed rimmed vacuoles and p62-positive intranuclear inclusions in the myofibers in both patients. The skin biopsy performed in one patient detected typical eosinophilic intranuclear inclusions. Genetic analysis identified CGG repeat expansion in NOTCH2NLC as the causative mutation in the two patients. Conclusions Our two patients with OPDM3 had clinical characteristics of NIID and exhibited DWI abnormality in the cerebellum. Our results indicate that OPDM3 is within the spectrum of NIID and that DWI hyperintensities in the cerebellum are helpful for diagnosing NIID or OPDM3.

Objective:To explore the intervention effect of sensorimotor training on cognitive function, balance and fall risk of elderly patients with schizophrenia.Methods:The 60 hospitalized elderly schizophrenic patients in Wuxi Mental Health Center were randomly divided into experimental group and control group from June to September 2021, with 30 cases in each group. The control group implemented traditional exercise on the basis of routine nursing. The experimental group received 8-week and 24 times sensorimotor training on the basis of the routine nursing. The Chinese version of the Mini Mental State Examination (MMSE) was used to assess the cognitive level of patients, the Modified Morse Fall Scale (MMFS) was used to assess the risk of falls, and the Berg Balance Scale (BBS) was used to assess the balance function.Results:After 8 weeks of intervention, the total score of MMSE was (26.72 ± 1.71), higher than the total score of the control group (22.36 ± 1.93), the factor scores of temporal orientation, spatial orientation, recollection, attention and calculation, memory and language ability in the experimental group were (4.90 ± 0.31), (4.72 ± 0.53), (2.86 ± 0.35), (4.66 ± 0.61), (2.83 ± 0.47), (6.76 ± 1.09), higher than scores of the control group (4.36 ± 0.56), (3.93 ± 0.66), (2.57 ± 0.50), (3.64 ± 1.03), (2.18 ± 0.67), (5.68 ± 1.02), and the difference was statistically significant( t values were 2.53-9.06, all P< 0.05). The total score of MMFS in the experimental group was (5.93 ± 1.49), which was lower than that in the control group (8.75 ± 2.30). The difference was statistically significant ( t=-5.51, P<0.01). The total score of BBS in the experimental group was (38.83 ± 1.71), which was higher than that in the control group (30.89 ± 1.93). The difference was statistically significant ( t=16.43, P<0.01). Conclusions:Sensorimotor training can improve the level of balance, cognitive function and reduce the risk of falls in elderly patients with schizophrenia.

Objective:To construct a recombinant herpes simplex virus 2 (HSV-2) expressing enhanced green fluorescent protein (EGFP) using clustered, regularly interspaced, short palindromic repeat/CRISPR-associated nuclease 9 (CRISPR/Cas9) technology.Methods:Four strategies for inserting exogenous EGFP gene into HSV-2 genome using CRISPR/Cas9 technology were designed: (1) conventional homology-directed repair: circular two homology arm donor-mediated gene knock-in; (2) linearized single homology arm donor-mediated gene knock-in; (3) homology-independent targeted integration; (4) conventional homology-directed repair-mediated by cell lines stably expressing Cas9 and sgRNA.Results:The recombinant virus HSV-2-EGFP was successfully constructed based on the second, the third and the fourth strategies. The second strategy was the most efficient, followed by the third and the fourth strategies. The purified recombinant virus could stably express green fluorescent protein in seven passages and shared similar growth characteristics in Vero cells to the parental virus.Conclusions:Linearized single homology arm donor could increase the efficiency of gene knock-in, and cell lines stably expressing Cas9 and sgRNA could increase the efficiency of gene knock-in mediated by homology-directed repair.

Objective:To investigate the effects of genomic location of a foreign gene in Shanghai-191 strain measles virus (MV) vector on gene expression and virus replication.Methods:The nucleotide sequence encoding S1 protein of SARS-CoV-2 was inserted at different positions in MV antigenome (the upstream of the N gene, between P and M genes, between H and L genes), and co-transfected into 293T cells with helper plasmids coding T7 RNA polymerase and N, P, and L proteins, respectively. The transfected cells were lysed and the supernatants were used to infected Vero cells to harvest recombinant viruses. S1 proteins expressed by the recombinant viruses were identified by RT-PCR, indirect immunofluorescence assay, Western blot and ELISA. Growth kinetics of the recombinant viruses were analyzed.Results:Recombinant viruses were failed to be rescued when the S1 protein-coding sequence was cloned into the upstream of N gene. Two recombinant viruses, MV-M-S1 and MV-L-S1, were successfully rescued when cloning the S1 protein-coding sequence into the intergenic region between P and M genes, or H and L genes, and could express S1 protein. MV-M-S1 expressed more S1 protein than MV-L-S1, but the titer of MV-M-S1 was lower.Conclusions:Inserting a foreign gene at different positions in the MV genome might have different effects on gene expression and virus replication. This study provided reference for the subsequent construction of MV vector.

Herpes simplex virus (HSV), the main pathogen of human herpetic diseases, is an attractive viral vector due to a wide range of host cell types and a large capacity of foreign gene. The manipulation on herpes simplex virus genome, up to 152 kb, has been the key process and has undergone the improvement from homologous recombination to bacterial artificial chromosome (BAC) and CRISPR/Cas9. However, homologous recombination is imperfect because the efficiency of recombination is relatively low and the product is too complex to purify. Construction of recombinant HSV based on BAC is time-and labor-consuming. Currently, CRISPR/Cas9 has been applied to genetic engineering of various species by more and more researchers due to its convenience, good repeatability, low cost, and then the manipulation of viral genome is more accurate and efficient. Application of CRISPR/Cas9 in the research of HSV gene function, HSV infection therapy and viral vector were summarized in this review, in order to provide reference for corresponding research.

AIM: To investigate the role and possible mechanism of gastrodin combined with dexamethasone in myocardial cell injury induced by oxygen-glucose deprivation. METHODS: Oxygen-glucose deprivation (OGD) model was established. The cells were divided into 5 groups: normal control group, OGD group, DEX group, GAS group and DEX+GAS group. The activity of myocardial cells was detected by CCK-8 test in each group. The activity of LDH was detected by colorimetry in each group. The apoptosis of myocardial cells was detected by TUNEL method in each group. The ELISA assay was used to detect the inflammatory factors in culture medium of myocardial cells in each group. Western blot was used to detect the expression of Notch1, Bax, Bcl-2 and Beclin1 in myocardial cells in each group.RESULTS: The results showed that GAS combined with DEX could significantly increase the activity of myocardial cells and decrease the apoptosis, reduce production of TNF-α, IL-6, IL-1β and promote production of IL-10, decrease the release of LDH significantly of myocardial cells induced by OGD. The results of Western blot showed that GAS combined with DEX increased the expression of Notch1, Bcl-2 and autophagy-related gene Beclin1, but decreased the expression of Bax of myocardial cells induced by OGD. CONCLUSION: The combination of GAS and DEX may promote autophagy and increase cell activity, inhibit apoptosis and inflammatory reaction by activating Notch signaling pathway, thereby reducing OGD-induced myocardial cells damage.
