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.

Objective:To investigate the effects of different tube voltages combined with artificial intelligence reconstruction algorithm(CI)on the computed tomography(CT)imaging quality and radiation dose of chest phantom on the basis of the CT scan for an adult male simulated chest phantom(PH-N1).Methods:A 512-slice CT scanner of ultrahigh-end was adopted to conduct scan,and the images were divided into 70 kV group,80 kV group,100 kV group and 120 kV group according to different tube voltage.For 4 groups of CT scan images with different tube voltages,the 10%,30%,50%,70%and 90%CI were adopted to reconstruct 1mm thin layer image.The CT volume dose index(CTDIvol)and the dose-length product(DLP)of the scans of 4 groups were compared.The CT values and standard deviation(SD)values of the aorta,abdominal wall fat and erector spine muscle were measured.Two senior diagnostic physicians with more than 5 years of work experience independently and double-blindly evaluated the image quality by using 5-point scale.A Kappa consistency test was conducted.One-way analysis of variance was adopted to compare the differences of CT values and SD values of the tissues of image targets.The Friedman rank-sum test was adopted to compare the differences of subjective image qualities among different groups.Results:The differences of CTDIvol and DLP among 4 groups with different tube voltages were significant(F=1855.617,3996.118,P<0.05),respectively.Under 70 kV tube voltage,there were no significant differences in CT values of the aorta,abdominal wall fat and erector spine muscle,which were reconstructed by using 10%,30%,50%,70%and 90%CI(P>0.05),while the differences of SD values among them were statistically significant(F=32.267,53.327,14.873,P<0.05),respectively.Under the different tube voltages of 4 groups,which were reconstructed by 90%CI,the CT values of aorta,abdominal wall fat and erector spine muscle gradually decreased with decreasing of tube voltage,the differences were significant(F=139.899,2563.93,219.231,P<0.05),respectively.The consistency of subjective scores between two diagnostic physicians was better for each group of images(Kappa=0.712～0.869).Conclusion:Compared with 80 kV,90 kV and 120 kV images,the reconstructed images with 90%CI algorithm under 70 kV tube voltage can significantly reduce the radiation dose,and the images have a favorable signal-to-noise ratio at the same time.

Objective To observe the effect of pre-hospital and intra-hospital collaborative ther-apeutic model in the treatment of patients with acute cerebral infarction.Methods A total of 67 pa-tients with acute cerebral infarction were selected as the research objects,and they were divided into observation group(n=37)and control group(n=30)according to the therapeutic model.The con-trol group was conducted with the traditional therapeutic model,while the observation group was con-ducted with the pre-hospital and intra-hospital collaborative therapeutic model.The time efficiency of intravenous thrombolysis,early recovery of nerve function and oxidative stress indexes were compared between the two groups.Results There was no significant difference in the time from onset to visit between the two groups(P＞0.05);the time from seeing a doctor to thrombolysis and the time from seeing a doctor to signing the informed consent for intravenous thrombolysis in the observation group were significantly shorter than those in the control group(P＜0.05).On the hospital admission,there was no significant difference in the National Institutes of Health Stroke Scale(NIHSS)score be-tween the two groups(P＞0.05);at the time points of 7 days after admission and 90 days after thrombolysis,the NIHSS scores of patients in the observation group were significantly lower than that in the control group(P＜0.05).There were no significant differences in the levels of serum glutathione peroxidase(GSH-Px)and malonaldehyde(MDA)between the two groups(P＞0.05);the level of serum superoxide dismutase(SOD)in the observation group was significantly higher than that in the control group(P＜0.05).One patient died in the control group,with a mortality rate of 3.33％;no patient died in the observation group.Conclusion Pre-hospital and intra-hospital collaborative therapeutic model can effectively improve the time efficiency of intravenous thrombolysis for patients with acute cerebral infarction,alleviate the neurological damage,and reduce degree of oxidative stress reaction and death risk.

Objective:To construct machine learning models based on CT imaging and clinical parameters for predicting progression-free survival (PFS) of locally advanced cervical cancer (LACC) patients after concurrent chemoradiotherapy (CCRT).Methods:Clinical data of 167 LACC patients treated with CCRT at Shandong Cancer Hospital from September 2015 to October 2021 were retrospectively analyzed. All patients were randomly divided into the training and validation cohorts according to the ratio of 7 vs. 3. Clinical features were selected by univariate and multivariate Cox proportional hazards model ( P<0.1). Radiomics models and nomograms were constructed by radiomics features which were selected by least absolute shrinkage and selection operator (LASSO) Cox regression model to predict the 1-, 3- and 5-year PFS. Combined models and nomogram models were developed by selected clinical and radiomics features. The Kaplan Meier-curve, receiver operating characteristic (ROC) curve, C-index and calibration curve were used to evaluate the model performance. Results:A total of 1 409 radiomics features were extracted based on the region of interest (ROI) in CT images. CT radiomics models showed better performance for predicting 1-, 3-and 5-year PFS than the clinical model in the training and validation cohorts. The combined model displayed the optimal performance in predicting 1-, 3-and 5-year PFS in the training cohort [area under the curve (AUC): 0.760, 0.648, 0.661, C-index: 0.740, 0.667, 0.709] and verification cohort (AUC: 0.763, 0.677, 0.648, C-index: 0.748, 0.668, 0.678).Conclusions:Combined model constructed based on CT radiomics and clinical features yield better prediction performance than that based on radiomics or clinical features alone. As an objective image analysis approach, it possesses high prediction efficiency for PFS of LACC patients after CCRT, which can provide reference for clinical decision-making.

【Objective】 To explore the clinical characteristics and risk factors of renal function deterioration in children with renal dysplasia and chronic kidney disease (CKD), so as to provide a basis for the diagnosis, treatment, and management. 【Methods】 The clinical data of children with renal dysplasia complicated with CKD treated in the Children’s Hospital of Chongqing Medical University during 2012 and 2022 were retrospectively analyzed, including the gender, age of diagnosis, growth index, concomitant malformation and complications. According to the diagnostic criteria and staging standard of KDIGO2020 guidelines, patients with disease deteriorated to CKD stage 4-5 were enrolled into the regression group. Factors affecting the deterioration of renal function were determined with Cox regression analysis. 【Results】 A total of 122 children were involved, including 66 (54.1%) with CKD stag 4-5. There were more boys than girls. Bilateral and unilateral renal dysplasia occurred in 88 (72.13%) and 34 (27.87%) cases, respectively, and 64 (52.46%) cases were complicated with other urinary diseases. There were significant differences in weight, height and body mass index (BMI) among patients with CKD stage 1-5 (P<0.01). The age of onset of CKD <10 years, BMI lower than the 3rd percentile of the same sex and age, bilateral renal dysplasia, and one or more complications of congenital renal and urinary tract abnormalities (CAKUT) were the risk factors of deterioration of renal function (P<0.05). 【Conclusion】 Renal dysplasia complicated with CKD are more common in boys, with high incidence of bilateral renal dysplasia. Bilateral renal dysplasia, age of onset of CKD <10 years, BMI lower than 3% and complications are important influencing factors of renal dysplasia in children with CKD.

Objective:To establish a candidate reference procedure for the enumeration of cell particles in urine and applied to the multi-center performance evaluation of an automated urine formed elements analyzer.Methods:According to the standardized mannual microscopic examination of fresh non-centrifuged urine samples and the recommended reference method for enumeration of cell particles in urine published by ISLH, we established a candidate reference procedure for the enumeration of cell particles in urine. From four class A tertiary hospitals′ clinical laboratories, three rigorous trained technicians per hospital tested the same specimen respectively using the reference procedure. Each specimen was repeatedly counted 5 times, obtaining the quantitative results of cell particles were obtained in urine. Four hospitals used the established candidate reference measurement procedure and the automated urine formed elements analyzer to detect 40 to 60 urine specimens from September 2020 to January 2021, and evaluate the established reference method, meanwhile evaluate the accuracy and consistency of the each count from automated urinalysis analyzer.Results:Using the candidate reference measurement procedures, the coefficient of variation of results derived from three trained technicians per hospital was less than 6.98% (red blood cells), 6.99% (white blood cells), 13.94% (epithelial cells) and met the quality requirements. The performance evaluation results of automated urine formed elements analyzer showed that the accuracy of red blood cells, white blood cells and epithelial cells met the requirements (bias≤4.98%) and was well consistent with the reference measurement procedure ( R2≥0.989). Conclusions:A candidate reference measurement procedure for the enumeration of urine cell particles was successfully established with satisfactory precision and accuracy. This procedure was applied to multicenter performance evaluation of an automated urine formed elements analyzer with good accuracy and consistency.

Primary lung cancer is the first malignant tumor in our country and in the world with an increasing mortality trend, which seriously endangers the human health. By digging the deep relationship between high-dimensional imaging features and pathophysiological features, radiomics can establish a predictive model to distinguish pathological types, tumor stages, distant metastases and survival, guide individualized diagnosis and treatment strategies, and improve prognosis. PET/CT has higher diagnostic accuracy and specificity by reflecting tumor tissue metabolism. This article reviews the application of PET/CT radiomics in the treatment of non-small-cell lung cancer (NSCLC).

Objective:To investigate clinical characteristics of acquired palmoplantar keratodermas (PPK) and the effect of metal implants (MIs) on plasma cytokines in patients with PPK.Methods:An observational study was conducted. Patients with acquired PPK were collected from Department of Dermatology, General Hospital of Eastern Theater Command from June 2020 to December 2021, and health checkup examinees during the same period served as controls. The PPK area and severity index was evaluated according to the eczema area and severity index, metal allergens were detected by metal patch test (MPT) , and plasma levels of cytokines, including tumor necrosis factor (TNF) -α, interferon (IFN) -γ, interleukin (IL) -4, IL-13, IL-17A and IL-8, were detected by enzyme-linked immunosorbent assay. Non-normally distributed measurement data were expressed as median (quartile 1, quartile 3) , and analyzed by rank sum test; intergroup comparisons of enumeration data were performed by chi-square test.Results:A total of 81 PPK patients were collected, including 42 males and 39 females, and their average age was 48 years (range, 21 - 65 years) . In vivo MIs were found in 37 (45.7%) patients, including dental implants in 34, orthopedic implants in 2, and cardiac implants in 1. During the same period, 36 healthy subjects were included in the control group, and there was no significant difference in the age and gender composition between the two groups ( P > 0.05) . No significant difference was observed in the PPK area and severity index between the MI group (37 cases, 0.40 [0.27, 0.75] points) and non-MI group (44 cases, 0.38 [0.19, 0.70] points; Z = 1.21, P = 0.225) . Forty-six patients in the PPK patient group and 30 in the control group were subjected to MPT, and the positive rate of MPT was significantly higher in the patient group (14/46) than in the control group (2/30, χ2 = 6.17, P = 0.013) , and was significantly higher in the patients with in vivo MIs (10/25) than in the patients without (4/21, adjusted P < 0.017) . Plasma cytokines were detected in 36 cases in the patient group and 36 in the control group. The plasma levels of TNF-α and IFN-γ were significantly lower in the patient group (66.2 [58.7, 69.3] pg/ml, 645.0 [571.5, 681.1] pg/ml, respectively) than in the control group (71.5 [64.5, 73.9] pg/ml, 716.5 [620.4, 785.0] pg/ml, respectively; both P < 0.05) , but there was no significant difference in the levels of plasma IL-4, IL-13, IL-17A and IL-8 between the two groups (all P > 0.05) . Conclusions:Positive MPT reaction is more common in acquired PPK patients, especially in patients with in vivo MIs. There may be a correlation between metal and acquired PPK, and changes in plasma TNF-α and IFN-γ levels may be related to the onset of some acquired PPK.

Postzygotic mutations are acquired in normal tissues throughout an individual's lifetime and hold clues for identifying mutagenic factors.Here,we investigated postzygotic mutation spectra of healthy individuals using optimized ultra-deep exome sequencing of the time-series samples from the same volunteer as well as the samples from different individuals.In blood,sperm,and muscle cells,we resolved three common types of mutational signatures.Signatures A and B represent clock-like mutational processes,and the polymorphisms of epigenetic regulation genes influence the pro-portion of signature B in mutation profiles.Notably,signature C,characterized by C＞T transitions at GpCpN sites,tends to be a feature of diverse normal tissues.Mutations of this type are likely to occur early during embryonic development,supported by their relatively high allelic frequencies,presence in multiple tissues,and decrease in occurrence with age.Almost none of the public datasets for tumors feature this signature,except for 19.6％of samples of clear cell renal cell carcinoma with increased activation of the hypoxia-inducible factor 1(HIF-1)signaling pathway.Moreover,the accumulation of signature C in the mutation profile was accelerated in a human embryonic stem cell line with drug-induced activation of HIF-1α.Thus,embryonic hypoxia may explain this novel signature across multiple normal tissues.Our study suggests that hypoxic condition in an early stage of embryonic development is a crucial factor inducing C＞T transitions at GpCpN sites;and indi-viduals'genetic background may also influence their postzygotic mutation profiles.
