Informed consent in psychological counseling is the first step for clients to initiate the counseling process， and the degree and effectiveness of informed consent are important factors that determine the subsequent effectiveness and development of psychological counseling. By elaborating on the connotation and importance of informed consent in psychological counseling， the ethical dilemmas of the issue of informed consent in psychological counseling were classified and summarized. There were ethical dilemmas， such as the lack of consensus， procedural guarantee mechanisms， special clients procedures and informed consent principles， as well as non-standard informed consent procedures in online psychological counseling. The paper also proposed to clarify the explanatory obligations of counselors， strengthen procedural ethical constraints， formulate special norms for informed consent for special subjects， and enhance the ethical education and capacity building of psychological counselors.

Ketamine， a non-competitive N-methyl-D-aspartate （NMDA） receptor antagonist， has gained increasing attention for its rapid antidepressant effects in treatment-resistant depression （TRD） and suicidal ideation. Its mechanisms include NMDA receptor blockade， AMPA receptor activation， and upregulation of BDNF/mTOR signaling. Its enantiomers， esketamine and R-ketamine， as well as its metabolites， exhibit differences in efficacy and mechanisms. Intranasal esketamine has been approved in the Europe， United States， and China for TRD， demonstrating rapid efficacy in alleviating depressive symptoms and acute suicidal ideation. In contrast， R-ketamine demonstrates potential for longer-lasting effects and a improved safety profile. This review summarizes recent advances in the pharmacology， pharmacokinetics， and clinical applications of ketamine and its enantiomers in depressive disorders， bipolar disorder， substance use disorders， post-traumatic stress disorder and obsessive-compulsive disorder. Despite ketamine's multifaceted therapeutic potential， safety concerns such as dissociation， cognitive impairment， and abuse liability warrant continued attention.［Funded by Key Project of Natural Science Research for Universities of Anhui Provincial Education Department （number， 2023AH050647）； Anhui Provincial Department of Education Outstanding Young Talent Support Program Project 2022 （number， gxyqZD2022022）］

Objective:To investigate the status of personnel, facilities, and technology of radiation therapy in Henan province in 2023.Methods:A unified online survey questionnaire was designed and distributed from March to April 2023 by the Henan Cancer Diagnosis and Treatment Quality Control Center to various medical institutions throughout the province to investigate the personnel, radiotherapy equipment, quality control equipment, imaging equipment, and radiotherapy technology development of each radiotherapy unit. Descriptive statistical methods were mainly used.Results:As of April 30, 2023, there were a total of 168 units engaged in radiation therapy in Henan province. The number of physicians involved in radiation therapy was 956, along with 365 medical physicists and 680 technicians. The equipment inventory included 212 medical linear accelerators, 1 cobalt-60 therapy machine, 32 afterloading therapy apparatuses, 4 Cyber Knife, 173 CT simulators, 2 MRI simulators and 94 conventional simulators. Linear accelerators were the primary radiotherapy equipment, 2.15 units per 1 million population on average. Additionally, there were 11 units offering 2D radiotherapy, 24 units offering 3D conformal radiotherapy, 130 units offering intensity-modulated radiotherapy, 41 units offering rotational intensity-modulated radiotherapy, and 33 units offering stereotactic radiosurgery. Regarding physical quality control equipment, 16 units were equipped with three-dimensional water tanks, 162 units were equipped with radiation dose meters, 114 units were equipped with morning check meters, 60 units were equipped with film dose meters, and 108 units were equipped with intensity adjustment plan verification systems.Conclusions:In 2023, there is a shortage of radiation therapy professionals in Henan province. Disparities are observed in the distribution of radiation therapy equipment among regions. Intensity-modulated radiotherapy has become the mainstream technology for radiation therapy in Henan province. The configuration of radiation therapy quality control equipment and standardized quality control work should be further improved.

Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

Objective To investigate the efficacy and safety of camrelizumab monoclonal antibody combined with molecular-targeted therapy in elderly patients with unresectable or advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the patients with unresectable/advanced HCC who attended six hospitals from January 1,2019 to March 31,2021,and all patients received camrelizumab monoclonal antibody treatment,among whom 84.8%also received targeted therapy.According to the age of the patients,they were divided into elderly group(≥65 years)and non-elderly group(＜65 years).The two groups were assessed in terms of overall survival(OS),progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),and immune-related adverse events(irAE).The chi-square test or the Fisher's exact test was used for comparison of categorical data between groups;the independent samples t-test was used for comparison of normally distributed continuous data,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.The Kaplan-Meier method was used for survival analysis,and the log-rank test was used for comparison of survival curves.Univariate and multivariate Cox proportional hazards regression analyses were used to determine the independent influencing factors for PFS and DCR at 6 months.Results A total of 99 HCC patients were enrolled,with 27 in the elderly group and 72 in the non-elderly group.The elderly group had an OS rate of 67.8%,an ORR of 44.4%,and a DCR of 74.1%at 12 months and a median PFS of 6.4(95%confidence interval[CI]:3.0-12.4)months,with no significant differences compared with the non-elderly group(all P＞0.05).The median OS was unavailable for the elderly group,while the non-elderly group had an OS of 18.9(95%CI:13.0-24.8)months;there was no significant difference between the two groups(P=0.485).The univariate and multivariate Cox regression analyses showed that major vascular invasion(MVI)was an independent risk factor for PFS(hazard ratio[HR]=2.603,95%CI:1.136-5.964,P=0.024)and DCR(HR=3.963,95%CI:1.671-9.397,P=0.002)at 6 months,while age,sex,etiology of HBV infection,presence of extrahepatic metastasis,Child-Pugh class B,and alpha-fetoprotein＞400 ng/mL were not associated with PFS or DCR at 6 months.For the elderly group,the incidence rates of any irAE and grade 3/4 irAE were 51.9%and 25.9%,respectively,with no significant differences compared with the non-elderly group(P＞0.05),and skin disease was the most common irAE in both groups(39.4%).Conclusion Camrelizumab monoclonal antibody combined with molecular-targeted therapy has similar efficacy and safety in patients with unresectable/advanced HCC aged≥65 years and those aged＜65 years.MVI is associated with suboptimal response to immunotherapy and poor prognosis.

Objective:To investigate the accuracy of magnetic resonance imaging (MRI) cine sequences in determining the range of tumor motion in radiotherapy, providing a basis for the precise delineation of the target volume in motion for radiation therapy.Methods:A modified chest motion phantom was placed in a MRI scanner, and a water-filled sphere was used to simulate a tumor. True fast imaging with steady precession (TrueFISP) MRI cine sequences from Siemens were used to capture the two-dimensional motion images of the simulated tumor. The phantom experiments were divided into three modes: head-foot motion mode, rotation motion mode, and actual respiratory waveform mode. In the head-foot motion mode, respiratory motion period (3, 4, 5, 6, 7 and 8 s), amplitude (5, 10 and 15 mm), and respiratory waveform of the simulated tumor (sin and cos4) were set, resulting in a total of 36 motion combinations. In the rotation motion mode, a cos4 waveform was used for respiration, with respiratory periods of 3, 4, 5, 6, 7 and 8 s, head-foot motion set amplitudes of 5, 10 and 15 mm, and anterior-posterior (AP) and left-right (LR) motion set amplitudes in three combinations ([2.5, 2.5] mm, [2.5, 5.0] mm, [5.0, 5.0] mm), resulting in a total of 54 motion combinations. In the actual respiratory waveform mode, respiratory waveforms of 5 randomly selected patients from Affiliated Cancer Hospital of Zhengzhou University were obtained. Under each motion combination, TrueFISP cine images (30 frames, with an acquisition time of 11 s per frame) were obtained. The code was used to automatically identify the two-dimensional coordinates of the center of the simulated tumor in each image, and sin and cos4 functions were separately employed to fit the tumor position in the motion direction, thereby obtaining the fitted motion period and amplitude. The difference between the maximum and minimum values of the tumor's center coordinates in the head-to-foot direction is taken as the range of movement, referred to as the calculated amplitude. For the actual respiratory waveform, the distance between the measured maximum and minimum positions is used to calculate the amplitude.Results:In the head-foot motion mode, the fitted amplitudes of both sin and cos4 waveforms deviated from the set amplitudes by 0-0.51 mm, with relative deviations of 0%-4.2%. The deviation range between the calculated amplitudes and the set amplitudes of the two waveforms were 0.08-0.94 mm, with relative deviations of 1.1%-6.3%. In the rotation motion mode, the fitted amplitudes deviated from the set amplitudes by 0-0.61 mm, with relative deviations of 0%-6.2%. And the deviation range between the calculated amplitudes and the set amplitudes were 0.16-0.94 mm, with relative deviations of 0%-6.3%. In the actual respiratory waveform motion mode, the deviation range between the calculated amplitudes and the set amplitudes were 0.10-0.48 mm, with relative deviations of 2.2%-8.6%.Conclusion:TrueFISP cine sequences show minimal deviations in determining the range of tumor head-foot motion and effectively captures the tumor's movement state, thereby providing important support for the precise definition of the tumor movement target area during radiotherapy .

Objective:To compare the postoperative effects of double eyelid surgery with different exophthalmos to find its influence on the surgery and necessary changes in preoperative design and during operation.Methods:A total of 50 female patients with single eyelid seeking beauty from June 2021 to March 2022 were selected from the Department of Plastic Surgery, Affiliated Hospital of Qingdao University. The ocular protrusion was measured by HETEL ophthalmostatometer before surgery. Both eyes at 12-15 mm were taken as normal group ( n=26), both eyes at 16-18 mm as mild protrusion group ( n=14) and both eyes at 19-22 mm as severe protrusion group ( n=10). All the patients were treated with double-eyelid surgery by orbital septum and unified postoperative nursing. Results:After six months of follow-up, there was no difference in eyelid width with closed eyes (all P>0.05). The width of double eyelid with open eyes in normal group was smaller than that in mild protrusion group ( F=23.23, all P<0.05), and the width of double eyelid with open eyes in mild protrusion group was smaller than that in severe protrusion group ( F=47.70, all P<0.05). There was no difference in the improvement rate of facial aesthetics among the three groups ( P>0.05). The " feeling of meet" and scar formation in the normal group were less than those in the mild protrusion group ( F=16.92, F=33.45, all P<0.05), and the " feeling of meet" and scar formation in the mild protrusion group were less than those in the severe protrusion group ( F=27.93, F=28.53, all P<0.05). The improvement rate of normal group was higher than that of mild and severe protrusion group (χ 2=7.25, 7.89, all P<0.05). There was no difference in the improvement rate between the mild and severe protrusion groups ( P>0.05). Conclusions:In clinical practice, it is necessary to make corresponding changes in the preoperative design and operation of double eyelid surgery for patients with high eyeball protrusion.

Objective:To propose an automatic planning approach for Eclipse15.6 planning system based on Eclipse scripting application programming interface (ESAPI) and evaluate its clinical application.Methods:20 patients with nasopharyngeal carcinoma and 20 cases of rectal cancer were selected in the clinical planning. The developed automatic planning script SmartPlan and RapidPlan were used for automatic planning and dosimetric parameters were compared with manual planning. The differences were compared between two groups by using Wilcoxon signed rank test. Results:The dosimetric results of automatic and manual plans could meet clinical requirements. There was no significant difference in target coverage in nasopharyngeal carcinoma planning between two groups ( P>0.05), and automatic plans were superior to manual plans in organs at risk sparing ( P<0.05). Except for the homogeneity index of PTV and the maximum dose of bowel in rectal cancer plans, the other dosimetric parameters of the automatic plans were better than those of the manual plans (all P<0.05). Conclusions:Compared with the manual plans, the automatic plans have the same or similar target coverage, similar or better protection of organs at risk, and more convenient implementation. The developed SmartPlan based on ESAPI has clinical feasibility and effectiveness.

Objective:To build a systemic and automatic importing scheme for importing CT images and structures into the treatment planning systems (TPSs) of Eclipse and Monaco.Methods:Based on two TPSs of Eclipse and Monaco, the files of CT images and structures were automatically transported from OAR auto-delineation system to the importing directory of these two TPSs using batch script in Windows system. Following the standard importing procedures of these two TPSs, the automatically importing script of CT images and structures were developed using the application of UiBot. Finally, the CT images and structures were imported into these two TPSs opportunely.Results:By comparing the importing time using script and manual methods, the script not only achieved auto-importing CT images and structures into TPSs, but also yielded almost the same efficiency to manual method. The number of imaging layers in most patients was between 130 and 180, and the average manual and automatic importing time within this interval was 76 s and 75 s.Conclusions:Automatic scripts can be developed by using the automation function of UiBot combined with the actual problems of radiotherapy and repeated workflow. The efficiency of radiotherapy work can be significantly improved. Manual and time costs can be saved. It provides a novel alternative for the automation of radiotherapy procedures.
