This paper summarizes Professor ZHAI Shuangqing's clinical experience in using metal and mineral medicines to treat mental disorders. Based on xiang thinking， the symptoms of mental disorders are classified into five categories， depression-xiang， wind-xiang， fire-xiang， phlegm-xiang， and deficiency-xiang， and the mechanisms of disease development are discussed accordingly. Metal and mineral medicines are key treatments for mental disorders， not only having the function of calming the mind but also promoting qi， stabilizing wind， expelling evil， and tonifying. In clinical practice， the emphasis is placed on harmonizing the disease and its symptoms. Based on self-developed prescription formulas， the appropriate metal and mineral medicines are selected according to the properties， flavors， meridian tropism， and actions of the medicines， as well as the xiang patterns of the mental disorder. For example， Attention Deficit Hyperactivity Disorder （ADHD） is treated by Modified Xiehuang Powder （泻黄散） with Sijunzi Decoction （四君子汤） and adding Fulonggan （Testudinis Carapax） and Longgu （Os Draconis）. Persistent insomnia is treated by combining a self-developed insomnia formula with Longgu （Os Draconis）， Hupo （Succinum）， and Cishi （Magnetitum）. Obsessive-compulsive disorder （OCD） is treated by combining a self-developed OCD formula with Longchi （Dens Draconis）， Qingmengshi （Fluoritum）， and Zheshi （Haematitum）. Epilepsy is treated by combining an anti-epilepsy decoction with Qingmengshi （Fluoritum）， Longchi （Dens Draconis）， and Shengtieluo （Ferrum Rudis）.

Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

AIM: To investigate the association between HOXA1 and FOXF2 gene variants and genetic susceptibility in multigenerational families with exotropia, and to elucidate the molecular genetic etiological mechanisms of exotropia.METHODS:A total of 10 multigenerational families with a definitive history of exotropia were recruited from September 2023 to February 2025, comprising 165 members(87 exotropia patients and 78 normal controls). Detailed ophthalmological examinations were performed, family pedigrees were constructed, peripheral blood samples were collected, genomic DNA was extracted, and PCR amplification followed by Sanger sequencing were used to detect exons and flanking sequences of the HOXA1 and FOXF2 genes. Identified variants were subjected to pathogenicity classification and association analyses.RESULTS:Among the 10 families, 5 variant sites in HOXA1(c.218G>A, c.385C>T, c.496A>G, c.652T>C, c.874C>T)and 4 in FOXF2(c.102C>T, c.344G>A, c.576T>C, c.892A>G)were identified. The HOXA1 c.496A>G variant showed statistically significant differences between carrier and noncarrier in exotropia angle, exotropia type, stereoscopic vision, and parallax(all P<0.05). The age of onset of FOXF2 gene c.344G>A mutation carrier group was younger than that of the non-carrier group(t=3.55, P=0.004).CONCLUSION:HOXA1 and FOXF2 gene variants are significantly associated with genetic susceptibility to exotropia, particularly influencing age of onset and deviation angle, offering novel targets for molecular diagnosis and precision treatment of exotropia.

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:To explore the clinical efficacy of areola approach endoscopic thyroidectomy (AET) and gasless axillary approach endoscopic thyroidectomy (GAET) in the treatment of papillary thyroid carcinoma (PTC) patients.Methods:A total of 96 PTC patients from the Thyroid Surgery Department of Linyi People’s Hospital from May. 2019 to May. 2022 were selected and randomly divided into 48 patients using a random number table method.

The intraoperative bleeding volume was (14.19±4.16) mL, which was less than that of the areola group (22.65±7.39) mL, and the number of lymph nodes cleaned was 5.06±1.02, which was more than that of the areola group (4.23±1.14) ( P<0.05) ; there was no significant difference in postoperative drainage volume and hospital stay between the two groups ( P>0.05) ; Peripheral blood WBC in the armpit group on the 1st and 3rd day after surgery [ (5.69±0.15) ×10 9/L, (5.52±0.14) ] ×10 9/L, ESR [ (8.21±0.55) mm/h, (7.64±0.60) mm/h], CRP [ (10.06±1.78) ng/L, (8.93±1.33) ng/L] were lower than those in the areola group [ (5.83±0.21) ×10 9/L, (5.70±0.23) ×10 9/L, (8.87±0.74) mm/h, (8.19±0.68) mm/h, (12.45±1.90) ng/L, (10.45±1.50) ng/L] ( P<0.05). There was no significant difference in the levels of the above biochemical indicators 5 days after surgery ( P>0.05). There was no significant difference in peripheral blood PTH and calcium levels between the two groups on the 1st, 3rd, and 5th postoperative days ( P>0.05). The pain level [ (3.25±0.32) scores, (2.53±0.27) scores, (1.82±0.22) scores] and discomfort level [ (6.85±0.71) scores, (5.24±0.66) scores, (3.51±0.57) scores] in the axillary group were lower than those in the areola group [ (3.78±0.40) scores, (2.89±0.34) scores, (2.06±0.26) scores, (7.46±0.84) scores, (6.09±0.73) scores, (4.16±0.60) scores] on the 1st, 3rd, and 5th postoperative days ( P<0.05). The neck flexion, lateral flexion, and extension range of motion in the axillary group on the 3rd day after surgery were (33.16±3.09) °, (27.63±2.57) °, and (30.44 2.73) °, respectively, which were greater than those in the areola group[ (30.08±2.76) °, (25.14±2.30) °, and (27.98±2.54) °], and the swallowing disorder index was (30.16±4.97) points lower than the (34.83±4.13) points in the areola group ( P<0.05). The incidence of complications in the axillary group was 4.17% (2/48), lower than the 16.67% (8/48) in the areola group. Conclusion:GAET treatment for PTC patients can improve the effect of lymph node dissection, reduce the degree of surgical trauma, postoperative pain and discomfort, accelerate early postoperative recovery of neck function, and reduce complications.

Objective To investigate the value of single photon emission computed tomography/computed tomography(SPECT/CT)fusion imaging for post-implantation dose verification of 125I particles in patients with bone metastases.Methods Forty patients with metastatic bone tumors treated with 125I particles implantation were selected.Within 24 h after 125I particles implantation,patients underwent SPECT/CT fusion imaging and the radioactivity per unit(RPU)was calculated.The treatment planning system(TPS)was then used to obtain the isodose profiles of SPECT/CT fusion imaging results and to calculate the tumor target coverage.The patient's preoperative and postoperative 1 month clinical outcomes,including local tumour remission,pain assessment,quality of life and serum alkaline phosphatase(ALP)levels were compared,and a receiver operating characteristic(ROC)curve was applied to evaluate the predictive value of tumor target coverage on postoperative outcomes.Results The mean number of particles implanted in the target area was 32.52±12.87.Within 24 h of 125I particles implantation,SPECT/CT fusion imaging analysis confirmed a strong positive correlation between the RPU of the radioactive concentration area and the mean dose received by the patient(r=0.786,P<0.05).The predicted area under the curve(AUC)for local tumor remission,pain relief,quality of life improvement and change in ALP levels was 0.789,0.757,0.804 and 0.833,respectively.Conclusion SPECT/CT fusion imaging can be used for postoperative dose verification of 125I particles for metastatic bone tumors and has some predictive value for clinical outcomes.

Objective To study the changes of tinnitus after cochlear implantation in post-lingual adault recip-ients and analyze the factors that affect tinnitus.Methods A total of 47 postilingually-deafened adult subjects with tinnitus who underwent cochlear implantation at the Department of Otology,the first affiliated hospital of Zheng-zhou University,from January 2017 to December 2021.The subjects were evaluated using tinnitus handicap invento-ry(THI)and visual analogue scale(VAS)before cochlear implantation and 6 months after cochlear implant surger-y.Results Among 47 subjects who were eligible for this study,the THI scores were 36.94±13.337,14.48± 12.726,respectively,before CI and 6 months after cochlear implantation.The VAS scores were 5.13±1.676 be-fore and 2.34±1.903 after cochlear tmplantation.Statistical analysis showed significant differences in THI and VAS scores before and after cochlear implantation(P＜0.05).A total of 18 patients experienced complete tinnitus suppression,14 patients experienced alleviation of tinnitus,tinnitus remained unchanged in 13 patients,tinnitus worsened in 2 patients,and the overall efficiency was 66.0％(31/47).The tinnitus alleviation rate was signifant higher in the patients with tinnitus history of ≤5 years than the patients with tinnitus history of＞5 years(P＜0.05).There was a statistically significant difference in tinnitus alleviation between the patients with mild tinnitus and the patients with more than mild tinnitus before surgery(P＜0.001).Conclusion Cochlear implantation has an inhibitory effect on tinnitus in adults.Patients with shorter duration of the tinnitus and higher tinnitus handicap are more likely to experience tinnitus improvement after cochlear implantation.

BACKGROUND:Pulmonary pericytes are located at the concavity where pulmonary vessels are interconnected,which is closely related to the formation and stability of pulmonary vascularization.However,there are few studies on how pulmonary pericytes affect the activity of pulmonary vascular endothelial cells in the pathogenesis of broncho-pulmonary dysplasia. OBJECTIVE:To analyze the relationship between the quantity of subgroups of pulmonary pericytes and endothelial cells in different stages of broncho-pulmonary dysplasia and to explore the effects of PDGFR-β+NG2+α-SMA+ pericytes on the early tube-forming activity of pulmonary vascular endothelial cells. METHODS:(1)Animal experiment:Twelve newborn C57BL/6 mice were randomly divided into normoxia and hyperoxia groups within 24 hours of birth,with six mice in each group.Mice in the hyperoxia group were exposed to an 85%O2 environment to build the mouse models of broncho-pulmonary dysplasia,while those in the normoxia group were fed in the same room air.The lung tissues of the mice in the two groups were taken at 7 and 14 days after birth.The pathological changes of the lung tissues were observed by hematoxylin-eosin staining.Three subgroups of pulmonary pericytes were measured by flow cytometry:PDGFR-β+NG2+α-SMA-,PDGFR-β+NG2+α-SMA+,and PDGFR-β+NG2-α-SMA+ cells.(2)Cellular experiment:Passage 3 PDGFR-β+NG2+α-SMA+ pericytes were co-cultured with mouse pulmonary vascular endothelial cells(experimental group)at a ratio of 1:4.Mouse pulmonary vascular endothelial cells cultured alone were used as controls.The tube-forming difference between two groups was analyzed after 15 hours of co-culture. RESULT AND CONCLUSION:(1)Animal experiment:Hematoxylin-eosin staining revealed that on day 7,the lung tissue of mice in the normoxia group had regular structure,obvious alveolar structure,and uniform size,while the number of alveoli in the lung tissue of mice in the hyperoxia group was less and the morphology of alveoli was irregular.On day 14,the alveoli of mice in the normoxia group gradually developed and matured,the alveolar structure gradually became regular and uniform in size,and the alveolar density gradually increased.The lung tissue structure of mice in the hyperoxia group was relatively disordered and the alveolar formation was delayed with the size gradually increasing and the alveolar structure being simplified.Flow cytometry results indicated that the number of PDGFR-β+NG2-α-SMA+ and PDGFR-β+NG2+α-SMA+ pericytes was increased in the hypoxia group compared with the normoxia group(P＜0.01),while the number of PDGFR-β+NG2+α-SMA-pericytes and pulmonary vascular endothelial cells was decreased(P＜0.01,P＜0.04).(2)Cellular experiment:In the control group,the pulmonary vascular endothelial cells arranged in cords and extended around,and lumen-like structures formed in some areas.In the experimental group,PDGFR-β+NG2+α-SMA+ pericytes and their pseudopodia were not observed,the irregular grid structure of pulmonary vascular endothelial cells was significantly less than that of the control group,and the endothelial cells mainly clustered in clumps.To conclude,α-SMA+ pericyte subgroups are predominant in mice with broncho-pulmonary dysplasia.PDGFR-β+NG2+α-SMA+ pericytes can directly inhibit the tube-forming activity of pulmonary vascular endothelial cells,which may be involved in the process of abnormal vascularization in broncho-pulmonary dysplasia.

Objective To establish a simultaneous detection approach for 34 emerging contaminants(ECs)in tap water by liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Human health risk assessment was performed according to the detection results from 43 tap water samples.Methods Tap water samples were concentrated and extracted by solid phase extraction,and then blown to near dry by nitrogen at 40℃.The sample extracts were dissolved in methanol-water solution(95:5,VN)to 0.5 mL for analyzing.Agilent Jet Stream Electrospray Ionization(AJS ESI)and the multiple reaction monitoring(MRM)mode were performed for MS to acquire the data of 34 ECs.A database including precursor ion,product ion and retention times was established accordingly.Results The average linear correlation coefficients(r)of 34 kinds of ECs was 0.995 9.The limits of detection were 0.01～0.60 ng/L and the recoveries were between 60.7％and 119.8％.The intra-group precisions were between 0.05％～9.89％and the intra-day precisions were between 0.20％～14.40％for the spiked samples.The method was applied to analyze 43 tap water samples and a total of 15 ECs were detected.According to the results,the detection rate of caffeine was the highest(84％),and the concentration range was ND～74.42 ng/L.Among all the ECs detected,1,2,3-benzotriazole had the highest concentration(ND～361.15 ng/L),where detection rate was 44％.Humans may be exposed to these ECs by drinking the tap water.The human health risk assessments of 12 kinds of ECs were carried out,however,the estimated risk was negligible(risk quotient＜0.01).Conclusion The method is simple,highly sensitive and selective,and could meet the detection needs of ECs at trace level in tap water.There was no human health risk posed for ECs identified in 43 tap water samples analyzed by this method.

Objective:To investigate the effects of low-frequency and high frequency repetitive transcranial magnetic stimulation (rTMS) combined with levodopa and benserazide hydrochloride on mild cognitive impairment in patients with Parkinson disease (PD).Methods:Totally 90 PD patients with mild cognitive impairment who visited from January 2020 to June 2022 were included , and they were divided into a simple drug group ( n=30), drug+ low-frequency group ( n=30), and drug+ high-frequency group ( n=30) according to the order of admission.The patients in the simple drug group were treated with oral levodopa and benserazide hydrochloride, while the patients in drug+ low-frequency and drug+ high-frequency groups were treated with low-frequency or high-frequency rTMS on the basis of oral levodopa and benserazide hydrochloride.Montreal cognitive assessment(MoCA), digital span (DS), Chinese auditory learning test (CALT), the judgment of line orientation test (JLOT) and verbal fluency test (VFT) were used to evaluate the cognitive function of patients before and after 4 weeks of treatment.SPSS 26.0 was used for statistical analysis.The paired t-test was used for intra-group comparison before and after treatment, while one-way ANOVA was used for inter-group comparison. Results:There were no significant differences in MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT, and VFT scores among patients in the simple drug group before and after 4 weeks of treatment( t=-1.157, -0.648, -0.215, -0.290, -0.154, -0.782, -0.960, all P>0.05). After 4 weeks of treatment, MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT scores in drug+ low-frequency group and drug+ high-frequency group were higher than before treatment (drug+ low frequency group: t=-16.357, -11.379, -7.999, -11.805, -16.624, -15.996, -17.241, all P<0.05; drug+ high-frequency group: t=-25.198, -13.971, -13.904, -25.831, -26.382, -20.108, -15.643, all P<0.05). There were no statistically significant differences in the scores of MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT among the three groups before treatment (all P>0.05). After treatment, there were statistically significant differences in the scores of MoCA, DS anterograde, DS backward, CALT immediate recall, CALT delayed recall, JLOT and VFT among the three groups (simple drug group : (20.37±1.96), (4.37±1.19), (2.80±0.55), (6.93±1.70), (5.17±1.09), (15.50±2.69), (10.73±1.55); drug+ low-frequency group: (23.83±2.32), (5.87±0.94), (3.87±0.73), (9.17±1.74), (8.13±1.50), (20.77±2.19), (13.30±1.73); drug+ high-frequency group: (27.17±1.64), (6.73±1.01), (4.80±0.81), (11.20±2.06), (10.03±1.54), (25.17±3.14), (15.87±2.05)) (all P<0.05). Further analysis showed that both the drug+ low-frequency and drug+ high-frequency groups had higher scores than the simple drug group, and the drug+ high-frequency group had higher scores than the drug+ low-frequency group(all P<0.05). Conclusion:The combination of drug+ low-frequency or drug+ high-frequency rTMS and drug therapy can help improve cognitive function in patients with PD, and the efficacy of drug+ high-frequency rTMS may be more significant, which provides a new therapeutic idea for clinical treatment of patients with PD.
