OBJECTIVE To explore comprehensive management and potential issues associated with long-term prescriptions medications of psychiatry， in order to provide a reference for the comprehensive management of long-term prescriptions of psychiatry in psychiatric hospitals and other medical institutions’ pharmacies. METHODS Starting from the applicable principles for long-term prescriptions of psychiatry， this study introduced the standardized assessment and precautions before issuing long-term prescriptions， the formulation and adjustment of the drug list， as well as the rational management of the long-term prescriptions. It also analyzed potential issues that may arise in the comprehensive management of long-term prescription medications and proposed corresponding countermeasures and suggestions. RESULTS & CONCLUSIONS Prior to initiating long-term prescriptions， a standardized assessment should be conducted on patients from the aspects of their psychiatric condition and long-term potential risk factors， pharmacological treatment plans and other non-pharmacological therapies， physical illnesses. Additionally， healthcare providers should fulfill their obligation to inform patients or their family members. The comprehensive management of long-term prescription medications should be jointly established and improved by multiple departments， and the formulation of drug catalogs should avoid including drugs with potential social harm or medication risks while complying with policy requirements. Furthermore， measures such as adding special identifiers to long-term prescriptions， providing patients with reminders about （No.YGLX202537） prescription expiration， or offering online consultations can also effectively enhance the rationality of medication use under long-term prescriptions. Currently， the implementation of long-term prescriptions in psychiatry remains challenged by inconsistencies in prescription duration， incomplete coverage of diagnostic categories， poor patient adherence， and the risk of deviation in clinical assessments. In this regard， measures such as collaborating with multiple departments to strengthen long-term prescription information management， providing matching pharmaceutical services， ensuring the quality and rationality of long-term prescription implementation， and using modern methods to screen high-risk patients can be taken to improve patient medication compliance and safety.

Objective:This study aims to analyze the threshold changes in distortion product otoacoustic emissions（DPOAE） and auditory brainstem response（ABR） in adult Otof-/- mice before and after gene therapy, evaluating its effectiveness and exploring methods for assessing hearing recovery post-treatment. Methods:At the age of 4 weeks, adult Otof-/- mice received an inner ear injection of a therapeutic agent containing intein-mediated recombination of the OTOF gene, delivered via dual AAV vectors through the round window membrane（RWM）. Immunofluorescence staining assessed the proportion of inner ear hair cells with restored otoferlin expression and the number of synapses.Statistical analysis was performed to compare the DPOAE and ABR thresholds before and after the treatment. Results:AAV-PHP. eB demonstrates high transduction efficiency in inner ear hair cells. The therapeutic regimen corrected hearing loss in adult Otof-/- mice without impacting auditory function in wild-type mice. The changes in DPOAE and ABR thresholds after gene therapy are significantly correlated at 16 kHz. Post-treatment,a slight increase in DPOAE was observeds,followed by a recovery trend at 2 months post-treatment. Conclusion:Gene therapy significantly restored hearing in adult Otof-/- mice, though the surgical delivery may cause transient hearing damage. Precise and gentle surgical techniques are essential to maximize gene therapy's efficacy.

Malignant tumors have surpassed stroke and coronary heart disease to become the main cause of death before the age of 70 in the world. The incidence of malignant tumors is increasing year by year， which seriously affects the living standards and social and economic development of Chinese people. Surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy are the main means of Western medicine to intervene in tumors， which are of great significance for prolonging the survival time of patients. However， there are many disadvantages such as adverse reactions and drug resistance. Traditional Chinese medicine has become a research hotspot in recent years because of its definite curative effect and wide application in tumor treatment. Xiao Chaihutang is derived from the Treatise on Febrile and Miscellaneous Diseases. It is composed of Bupleuri Radix， Scutellariae Radix， Ginseng Radix， Pinelliae Rhizoma， Glycyrrhizae Preparata Radix， Ginger， and Jujube. It has the effects of reconciling Shaoyang， reconciling cold and heat Yin and Yang， soothing the liver， and relieving depression. This prescription and the prescriptions based on it are widely used in various stages of tumors. This study summarized the Chinese and foreign research of Xiao Chaihutang in the field of tumors in the past 10 years and explored the role and mechanism of Xiao Chaihutang in blocking precancerous lesions， controlling the development of malignant tumors， reducing the occurrence of adverse reactions after intervention， and alleviating common complications， with a view to expanding the clinical medication ideas.

Objective To observe the influence of different energy windows of the medium-energy general-purpose(MEGP)collimator on image quality,so as to optimize the energy window of yttrium-90(90Y)bremsstrahlung SPECT imaging.Methods 90Y bremsstrahlung spectrum was acquired,and the sensitivity,percentage of the source counts in useful field of view(S/FOV%)and signal-to-background ratio(S/B)of 90Y bremsstrahlung SPECT imaging at MEGP under different energy windows were compared.Results The energy spectrum of 90Y bremsstrahlung was a continuous curve,with the peak of 76.2 keV with MEGP collimator.The images obtained with MEGP collimator were clear,and no significant differences of S/FOV%nor S/B was found between 10%and 20%window width groups(both P＞0.05),but the sensitivities of the latter was higher than the former(P＜0.05).The sensitivity of 70-90 keV images was relatively high,while the S/FOV%and S/B had decreased.The S/FOV%and S/B of images ranging from 40-60 keV were high,but the sensitivity was low.Images acquired with 100 keV±20%showed fairly high sensitivity,S/FOV%and S/B,which was 69.73%,0.62 and 1.64,respectively.Conclusion When performing 90Y bremsstrahlung SPECT with MEGP collimator,the image quality at 20%window width was better than at 10%window width,and 100 keV±20%showed fairly high sensitivity and not significantly decreased S/FOV%and S/B.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective This study aims to observe the clinical effect of bone plate reduction in combination with a re-sorbable plate on large mandibular cysts.Methods Between October 2017 and September 2022,patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study.Intraoral approach was performed for bone plate reduction.Cone beam computed tomography(CBCT)scan was reviewed at 3,6,and 9 months postoperatively to observe postoperative complications.Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure.Results Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated.The average thickness of the cortical bone on the labial and buccal sides was measured to be about(1.98±0.37)mm before surgery,with a mean value of(0.73±0.17)mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate.The cystic cavities were well re-vealed during the surgeries,which were completed suc-cessfully.Postoperatively,the wounds healed in one stage without infection.The percentages of cyst shrinkage were 20.01%,41.76%,and 73.41%at 3,6,and 9 months after surgery,respectively.Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software.The bone mineral densities of the adult bone were 313.78,555.85,and 657.45 HU at the 3,6,and 9 month time intervals,respectively.No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale.Conclusion Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial re-gion with the presence of cortical bone.

Objective To study the relationship between serum Melatonin,macrophage inflammatory pro-tein-1α(MIP-1α)and nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)inflamma-some and prognosis in children with acute respiratory distress syndrome(ARDS).Methods A total of 140 children with ARDS who were admitted to the hospital from January 2021 to January 2023 were enrolled as the ARDS group,and 100 healthy children who underwent physical examination during the same period were enrolled as the control group.According to the clinical outcome on 28 d after admission,the children with ARDS were divided into a death group(29 cases)and a survival group(111 cases).Enzyme-linked immu-nosorbent assay was used to detect the serum levels of Melatonin,MIP-1α,interleukin(IL)-1β,and IL-18.Re-al-time fluorescent quantitative PCR was used to detect the mRNA levels of NLRP3 and Caspase-1.Pearson correlation was used to analyze the correlation between serum levels of Melatonin and MIP-1α and NLRP3 in-flammasome related indicators(NLRP3 mRNA,Caspase-1 mRNA,IL-1β,IL-18)in children with ARDS.Mul-tivariate Cox regression analysis was used to analyze the factors affecting the prognosis of children with ARDS.According to the mean levels of serum Melatonin and MIP-1α,the children with ARDS were divided in-to a high/low Melatonin group and MIP-1α group.The Kaplan-Meier method was used to draw the survival curves of ARDS children with high/low levels of serum Melatonin and MIP-1α.The receiver operating charac-teristic(ROC)curve was used to analyze the predictive value of serum Melatonin and MIP-1α for death in children with ARDS.Results Compared with the control group,the ARDS group had a significantly decreased serum Melatonin level and significantly increased serum MIP-1α,IL-1β,IL-18 and NLRP3 mRNA and Caspase-1 mRNA levels in peripheral blood mononuclear cells(P＜0.05).Pearson correlation analysis showed that the serum Melatonin level of ARDS children was negatively correlated with NLRP3 mRNA,Caspase-1 mRNA,IL-1β and IL-18(P＜0.05),the level of MIP-1α was positively correlated with NLRP3 mR-NA,Caspase-1 mRNA,IL-1β and IL-18(P＜0.05).Multivariate Cox regression analysis showed that acute physiology and chronic health evaluation Ⅱ score,NLRP3 mRNA,Caspase-1 mRNA,IL-1β,IL-18 and MIP-1αwere independent risk factors affecting the prognosis of children with ARDS.Melatonin was an independent protective factor(P＜0.05).Kaplan-Meier survival curve analysis showed that the 28 d survival rate in high Melatonin group was higher than that in low Melatonin group(P＜0.05),and the 28 d survival rate in high MIP-1α group was lower than that in low MIP-1α group(P＜0.05).ROC curve analysis showed that the area under the curve of Melatonin and MIP-1α combined to predict the death of ARDS children was 0.881(95％CI 0.816-0.930).It was higher than 0.785(95％CI 0.708-0.850)and 0.778(95％CI 0.700-0.844)predic-ted by Melatonin or MIP-1α alone.Conclusion The serum Melatonin level is decreased and MIP-1α level is in-creased in children with ARDS,which is closely related to NLRP3 inflammasome and prognosis.Combined de-tection of serum Melatonin and MIP-1α levels has a high predictive value for the prognosis of children with ARDS.

Objective To develop and evaluate the equivalence of the Mandarin test material for tracking of noise tolerance(TNT)test.Methods Six different speech materials were developed(themes including daily life,entertainment,family,festivals,outdoors,and school).Four-minute TNT tests were measured in 21 normal hear-ing subjects using six different test materials.For each session,the tolerable noise level(TNL)and TNT scores were acquired and calculated for 3 time windows(31～240 s,31～120 s,151～240 s).Results Statistic analysis showed significant differences in the TNL(F=43.611,P＜0.05)among the normal hearing listeners.There were statistically significant differences in standardize z-scored TNT scores of the six different materials in the three time windows(P＜0.05).Post-hoc comparisons revealed that all significant differences involved the family and daily life themes.Conclusion Entertainment,festival,outdoors and school themed test materials can serve as the materials of Mandarin tracking of noise tolerance test and can be appied in research and clinical testing.
