Attention deficit hyperactivity disorder （ADHD） is often accompanied by tic disorder. The core pathogenesis is considered to be ministerial fire scorching yin and internal stirring of deficient wind， which leads to disharmony between the body and spirit， resulting in clinical manifestations. The treatment principles emphasize nourishing yin fluids， calming ministerial fire， and extinguishing endogenous wind （内风）. The method of nourishing yin fluids is applied throughout the entire treatment process， commonly using ingredients such as Shudihuang （Rehmanniae Radix Praeparata）， Shanzhuyu （Corni Fructus）， Gouqizi （Lycii Fructus）， Wuweizi （Schisandrae Chinensis Fructus）， and Tusizi （Cuscutae Semen）. These are combined with approaches to harmonize the zang-fu organs， primarily including extinguishing liver wind， clearing heart fire， nourishing kidney water， and strengthening spleen earth， thereby stabilizing ministerial fire and extinguishing endogenous wind. Additionally， emotional regulation and smoothing emotional constraint are essential to improve clinical symptoms in children with ADHD comorbid with tic disorder.

ObjectiveTo observe the effect of Yulin Hukun decoction on autophagy mediated by phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway in the mouse model of cyclophosphamide-induced diminished ovarian reserve and explore the follicular development-improving mechanism of this decoction. MethodsSixty female ICR mice with normal estrous cycle were assigned into a blank group （n=10） and a modeling group （n=50）. The model was established by intraperitoneal injection of cyclophosphamide （60 mg·kg^-1） for 5 days. The successfully modeled mice were randomly grouped as follows： model， estradiol （0.26 mg·kg^-1）， and high-， medium-， and low-dose （56.42， 28.21， 14.105 g·kg^-1， respectively） Yulin Hukun decoction， with 10 mice in each group. The blank group and the model group received normal saline （10 mL·kg^-1）. The intervention was performed once a day for 21 days. The general conditions， estrous cycle， body weight， and ovary index were observed and recorded for each group. Serum levels of follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol （E₂）， and anti-Müllerian hormone （AMH） were measured by enzyme-linked immunosorbent assay. Histopathological changes in the ovarian tissue were observed by hematoxylin-eosin staining. Western blot was employed to determine the protein levels of PI3K， Akt， mTOR， autophagy-related protein 7 （Atg7）， beclin1， microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ）， ubiquitin-binding adaptor protein （p62）， forkhead box protein O1 （FoxO1）， and acetylated forkhead box protein O1 （Ac-FoxO1） in mouse ovaries. Real-time PCR was adopted to determine the mRNA levels of PI3K， Akt， mTOR， Atg7， beclin1， and LC3Ⅱ in the mouse ovarian tissue. ResultsCompared with the blank group， the model group had disturbed estrous cycle， decreased body weight （P<0.05）， loose ovarian structure with increased atretic follicles， increased serum FSH level （P<0.05）， and decreased AMH and estradiol levels （P<0.05）. Compared with the model group， the treatment groups showed recovered estrous cycles and body weight. The estradiol group and high- and medium-dose Yulin Hukun decoction groups showed declined FSH level （P<0.05） and elevated AMH levels （P<0.05）. In addition， the treatment groups showed downregulated protein levels of Atg7， LC3Ⅱ， beclin1， FoxO1， and Ac-FoxO1 （P<0.01）， upregulated protein levels of PI3K， Akt， mTOR， and p62 （P<0.01） in the ovarian tissue， gradual repair of the ovarian structure， with more intact and numerous follicles of various stages. ConclusionYulin Hukun decoction can inhibit autophagy in ovarian granulosa cells by activating the PI3K/Akt/mTOR signaling pathway and inhibiting the expression of autophagy-related proteins and transcription factors， thereby improving follicular development and ovarian reserve.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Lung cancer is the leading cause of cancer-related deaths worldwide. Radiation pneumonitis is a major complication in lung cancer radiotherapy. Four-dimensional computed tomography (4DCT) imaging provides dynamic ventilation information, which is valuable for lung function assessment and radiation pneumonitis prevention. Many methods have been developed to calculate lung ventilation from 4DCT, but a systematic comparison is lacking. Prediction of radiation pneumonitis using 4DCT-based ventilation is still in an early stage, and no comprehensive review exists. This paper presented the first systematic comparison of functional lung ventilation algorithms based on 4DCT over the past 15 years, highlighting their clinical value and limitations. It then reviewed multimodal approaches combining 4DCT ventilation imaging, dose metrics, and clinical data for radiation pneumonitis prediction. Finally, it summarized current research and future directions of 4DCT in lung cancer radiotherapy, offering insights for clinical practice and further studies.

Objective To observe the value of quality control system based on artificial intelligence(AI)for improving imaging quality of chest CT.Methods Totally 1 726 CT images obtained from 415 patients were retrospectively collected,among which 1 414 images were used for convolutional neural network(CNN)training and the rest 312 images were used for validation.Precision,Recall,F1-Score,mean average precision(mAP)and intersection over union(IOU)of quality control system based on AI for chest CT scanning were calculated.Meanwhile,21 patients with unsatisfactory chest CT who would undergo re-examination were prospectively enrolled,and chest CT scanning with quality control system based on AI were performed.The results of 2 examinations were compared.Results Precision,Recall,F1-Score,mAP and IOU of quality control system based on AI for chest CT were all good.All 21 cases were diagnosed correctly with re-examination CT based on quality control system.Among 21 cases,the first CT misdiagnosed 19 cases,the displaying of the area,volume and display quality of pulmonary nodules were not significantly different,but the morphology,boundaries,spiny protrusions,vacuolar signs,inflatable bronchial signs of nodules as well as the thickened and twisted blood vessels were obviously different between 2 times examination.The first CT missed 1 case while correctly diagnosed 1 case.Conclusion The quality control system based on AI was helpful for improving imaging quality of chest CT and increasing diagnostic efficacy.

Objective To investigate the effect of early warning score system combined with(situation,background,ssessment,recommendation,SBAR)communication model in early warning of high-risk neonates,therefore to provide an effective communication method for an effective communication method to assess the changes of condition in neonates.Methods A before-after study model was adopted in the study.A total of 270 high-risk neonates admitted to the ward of the Department of Neonatology in a tertiary hospital between August and September 2022 were selected as research subjects.The high-risk neonates admitted in hospital in August were assigned in a control group,and those admitted in September were assigned in an trial group,with 135 neonates per group.Routine care was carried out in the control group,while early warning scoring combined with SBAR communication model were applied in the trial group on top of the cares offered to the control group.The occurrence of early warning events,concordance rate of nurse warning event and doctor handling events,and the satisfaction rate of doctors with the nursing performance were compared between the two groups.Results A total of 63.6%of early warning events were triggered by nurses in the control group,while it was 92.6%in the trial group,with a statistically significant difference between the groups(χ2=16.622,P<0.001).The consistency of handling of early warning events between the nurses and doctors in the trial group(Kappa coefficient=0.926)was higher than that in the control group(Kappa coefficient=0.641).The satisfaction rates of the doctors with the nurses about specialist knowledge,ability in emergency events,mastery of disease,timely observation of disease progress,collaboration between doctors and nurses,working enthusiasm,communication capability and the psychological quality in the trial group were all significantly higher than those in the control group[80.0%-95.0%vs.30.0%-55.0%,all P<0.01].Conclusions The Early Warning Score system combined with SBAR communication model can help nurses to accurately evaluate the changes of disease in neonates,complete the communication with doctors timely and effectively.It improves the observation,communication and handling capability among the nurses as well as the satisfaction rate of doctors with nursing work.

BackgroundNegative effects of mobile phone addiction on undergraduate students have led to several health problems including depression， anxiety， attention deficit disorder， cognitive impairment and sleep disturbance. The undergraduate nursing students serve as an important reserve force of the clinical nursing work， and their poor psychological health would have a non-ignorable impact on the quality of the nursing work and the nurse-patient relationship in the future. ObjectiveTo investigate the relation between neuroticism and tendency of mobile phone addiction among undergraduate nursing students， and to examine the pathways through which perceived stress and self-control play a role in the relation by constructing a chain-mediated model. MethodsFrom February to March 2023， a total of 900 undergraduate nursing students across 10 universities in Xi'an， Shaanxi Province were selected through convenient sampling method. Several scales were adopted to assess undergraduate nursing students respectively， including the neuroticism subscale of Eysenck Personality Questionnaire-Revised Short Scale for Chines （EPQ-RSC）， Perceived Stress Scale （PSS）， Self-Control Scale （SCS） and Mobile Phone Addiction Tendency Scale （MPATS）. The assessment were conducted on multiple aspects of these students including neurotic personality， subjective stress， self-control and mobile phone addiction tendency. Model 6 in the SPSS Macro Process 4.1 was used to examine the mediating effect of perceived stress and self-control between neuroticism and mobile phone addiction tendency among undergraduate nursing students. Results① Among the 900 students， 314 cases （34.89%） were found to be addicted to mobile phones. ② The score of neuroticism subscale in EPQ-RSC of nursing undergraduates was positively correlated with the total scores of PSS and MPATS （r=0.400， 0.287， P<0.01）， and negatively correlated with score of SCS （r=-0.364， P<0.01）. The total score of MPATS was positively correlated with the total score of PSS （r=0.362， P<0.01）， and negatively correlated with the total score of SCS （r=-0.468， P<0.01）. The total score of SCS was negatively correlated with the total score of PSS （r=-0.515， P<0.01）. ③ Perceived stress and self-control performed partial mediation between neuroticism personality and mobile phone addiction tendency （with indirect effect values of 0.056 and 0.065， respectively， accounting for 19.72% and 22.89% of the total effect）. Perceived stress and self-control played a chain mediating role between neuroticism personality and mobile phone addiction tendency （with an indirect effect value of 0.064， accounting for 22.54% of the total effect）. ConclusionNeuroticism personality， perceived stress and self-control are confirmed to play important roles in mobile phone addiction tendency among undergraduate nursing students. Neuroticism personality not only directly affects the tendency of mobile phone addiction， but also affects their mobile phone addiction tendency through the chain mediating effect of perceived stress and self-control.［Funded by The 2020 Annual Project of the 13th Five-Year Plan of Education Science in Shaanxi Province （number， SGH20Y1386）］

Objective:To compare the efficacy and safety of low-dose and standard-dose radiotherapy (LD-RT vs. SD-RT) in the treatment of oropharyngeal cancer patients with positive human papillomavirus (HPV). Methods:All comparative studies of low-dose versus standard-dose radiotherapy in the treatment of HPV-positive oropharyngeal cancer were searched from PubMed, Web of Science, Cochrane Library, EMbase, Chinese Biomedical Literature Database (CBM), CNKI, Chongqing VIP, and Wanfang databases from January 1, 2000 to February 9, 2023. According to the inclusion and exclusion criteria, the data were strictly screened, and the RevMan 5.4 software was used for meta-analysis.Results:A total of 8 studies were included. The pooled results showed that the overall survival (OS) and progression-free survival (PFS) of patients in the LD-RT group were similar to those in the SD-RT group ( HR=0.83, 95% CI=0.59-1.18, P=0.31; HR=0.97, 95% CI=0.53-1.78, P=0.92), but the rate of percutaneous endoscopic gastrostomy (PEG) insertion was significantly reduced ( RR=0.45, 95% CI=0.28-0.72, P=0.001). Conclusion:LD-RT yields similar efficacy and lower rate of PEG insertion compared with SD-RT in HPV-positive oropharyngeal neoplasm patients.
