BACKGROUND:Ossification of the ligamentum flavum was previously considered to be rare in the population.As research has progressed,its incidence rate is increasing gradually,which has aroused the interest of a large number of researchers. OBJECTIVE:To visualize and analyze the research results on ossification of the ligamentum flavum from the Web of Science Core Collection since 1999 using bibliometric methods,and to review the research history of ossification of the ligamentum flavum,highlighting important literature,summarizing research hotspots,and providing ideas for researchers to find research directions. METHODS:Using the Web of Science Core Collection as the data source,relevant papers on ossification of the ligamentum flavum were searched and screened.VOSviewer 1.6.19 and CiteSpace 6.2.R6 were used to conduct the visual analysis of annual publication volume,research countries,institutions,citations,journals,authors,and keywords. RESULTS AND CONCLUSION:(1)A total of 347 papers were included.Since 1999,the number of published papers has increased in a spiral pattern.China's research started later than Japan's,but the number of publications has come up later,with Peking University being the institution with the most publications,and Prof.Chen Zhongqiang from Peking University being the scholar with the most publications.(2)Five of the 10 most frequently cited publications were related to the surgical treatment of the disease.(3)Excluding keywords directly related to the research topic and synthetically analyzing frequencies and betweenness centralities of key words,terms such as"thoracic myelopathy,""dural ossification,""minimally invasive surgery,"and"ossification of the posterior longitudinal ligament"occupied a central position in this field.(4)Keywords clustering analysis showed that clinical manifestations and surgical treatment of ossification of the ligamentum flavum accounted for a large proportion of study.(5)The timeline and burst analysis of keywords revealed that"minimally invasive surgery"appeared as a keyword around 2015,with the highest burst strength and the latest burst start time,and began to receive extensive attention from researchers in 2019.The burst of the keyword"dural ossification"has not yet ended.(6)Surgical treatment for ossification of the ligamentum flavum has been at the forefront of research.Development and research of minimally invasive surgery and research on dural ossification secondary to ossification of the ligamentum flavum are both current research hotspots and possible future research trends.

Parkinson’s disease （PD） is a common chronic neurodegenerative disease with movement disorders as the main clinical manifestation. The nuclear factor-erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） signaling pathway is closely associated with the occurrence and progression of PD. TCM flavonoid monomers （luteolin， rutin， etc.）， alkaloids （camptothecin， sinomenine， and alkaloids extracted from Uncaria rhynchophylla）， terpenes （tanshinone ⅡA， carvacrol， paeoniflorin）， phenols （ellagic acid， rosmarinic acid）， saponins （ginsenoside RK1）， and traditional Chinese medicine compounds （Wuzi yanzong pill and PD formula-2） can resist oxidative stress damage， inhibit inflammatory responses and abnormal aggregation of α-synuclein， and regulate neurotrophic factors by activating the Nrf2/HO-1 signaling pathway， thereby alleviating dopaminergic neuronal damage.

ObjectiveTo develop a standardized living will manual suitable for promotion in China， combining existing literature and the current implementation status of living will both domestically and internationally as well as the characteristics of modern medicine. MethodsA pool of manual entries was constructed through hospital interviews and literature retrieval. A Delphi method expert correspondence was conducted to modify and supplement the manual entry settings. The results of the correspondence were statistically analyzed to verify the reliability and scientific validity of the manual and the correspondence. ResultsThis study constructed a pool of manual entries by conducting interviews in four hospitals in Beijing and retrieving and including 155 pieces of literature，and developed a preliminary version of the manual with a total of 40 entries in four sections， namely medicine， psychology， society， and farewell. The manual items were revised through two rounds of the Delphi method correspondence with a total of 88 experts. The expert response rates in the two rounds of the correspondence questionnaires were 100% and 90%， respectively； the expert authority coefficients were 0.84 and 0.865， respectively； and Kcndall W was 0.141 and 0.077， respectively. In terms of the reliability test， the Cronbach’s α coefficients of the two rounds of correspondence were 0.941 and 0.969， respectively， and the Guttman coefficients were 0.862 and 0.857， respectively. As for the validity test， the Pearson correlation coefficient for 39 entries was R>0.4 in the first round of correspondence， and for 41 entries was R>0.4 in the second round of correspondence； a total of 20 entries in the first round of correspondence had an I-CVI ≥ 0.780， and the scale’s S-CVI was 0.786； a total of 31 entries in the second round of correspondence had an I-CVI ≥ 0.780， and the scale’s S-CVI was 0.846.

Objective To investigate the clinical effect and hearing loss of endolymphatic sac decompression(ESD)combined with one or two semicircular canal obstruction(SCO)in treating the patient with stage Ⅲ or stageⅣ Meniere disease.Methods Forty-three patients with stage Ⅲ or stage Ⅳ Meniere disease,who failed to respond to conventional conservative treatment and had the expectation of preserving residual hearing function,were enrolled in the study.They were divided into three groups according to the operation they underwent:ESD combined with lateral and posterior semicircular canal obstruction(ESD+LPSCO)13 cases,ESD combined with lateral semicircu-lar canal obstruction(ESD+LPSCO)14 cases,and ESD only 16 cases.Data of vertigo,ear fullness and tinnitus be-fore and after operation was collected,analyzed and compared.Hearing function before and after the operation was also evaluated.Results The number of vertigo attacks in the three groups(ESD+LPSCO,ESD+LSCO,and ESD)were all significantly reduced after operation.The vertigo control rate were 92.3％,78.6％and 62.5％re-spectively.Compared with pre-operation,the vertigo severity post-operation in the three groups were also signifi-cantly reduced.And the improvement rate of vertigo severity after ESD+LPSCO and ESD+LSCO were both 100％,which were significantly higher than that of ESD(68.8％).The discomfort of tinnitus and ear fullness in the three groups were significantly improved compared with that of pre-operation.The improvement rates of tinnitus in the three groups were 46.2％,50.0％and 43.8％respectively,with no significant difference.The improvement rate of ear fullness in the three groups were 61.5％,57.1％and 50.0％respectively,with no significant difference either.The proportion of patients with decreased hearing after operation in the three groups was 15.4％,7.1％and 18.8％,respectively,and the differences were insignificant.Conclusion ESD combined with one or two SCO can effectively control vertigo and other symptoms of patients with stage Ⅲ or Ⅳ Meniere's disease who had failure to conventional conservative treatment,and can preserve the residual hearing function in considerable extent.

ObjectiveTo mine the medication patterns of Chinese medicines for neurodermatitis based on contemporary medical cases in published articles. MethodThe medical cases of treating neurodermatitis with Chinese medicines were retrieved from the medical case articles published by contemporary famous and old Chinese medicine doctors in the library of Shandong University of Traditional Chinese Medicine， CNKI， VIP， and Wanfang Data. A case library was established， and SPSS Statistics 26.0 and SPSS Modeler 18.0 were employed to analyze the symptoms and syndromes of neurodermatitis and mine the medication patterns. ResultAccording to the inclusion and exclusion criteria， 130 medical case articles were included in this study. Neurodermatitis was prevalent in young adults between 20 and 39 years old （female patients of 30-49 years old and male patients of 20-39 years old）， and male patients were more than female patients. The patients mainly presented the clinical manifestations of itchy rashes， thickened skin， and lichenification. Symptoms included skin injury， emotional abnormalities， and Yin damage caused by prolonged illness. Red tongue， thin white or yellow tongue coating， and wiry pulse were common in the patients. The patients with the syndrome of blood deficiency and wind dryness were often treated with Angelicae Sinensis Radix， Rehmanniae Radix， Glycyrrhizae Radix et Rhizoma， Tribuli Fructus， and Chuanxiong Rhizoma. The commonly used herb pairs included Chuanxiong Rhizoma-Paeoniae Radix Alba， Chuanxiong Rhizoma-Glycyrrhizae Radix et Rhizoma， and Rehmanniae Radix Praeparata-Saposhnikoviae Radix， and the commonly used prescriptions were Siwutang and Dangguiyinzi. The patients with the syndrome of muscle and skin dystrophy were mainly treated with Rehmanniae Radix， Sophorae Flavescentis Radix， Paeoniae Radix Alba， Tribuli Fructus， and Dictamni Cortex. The commonly used herb pairs included Polygoni Multiflori Caulis-Sophorae Flavescentis Radix， Polygoni Multiflori Caulis-Dictamni Cortex， and Salviae Miltiorrhizae Radix et Rhizoma-Paeoniae Radix Alba， and the commonly used prescriptions were Jingjie Siwutang and Baixianpiyin. The patients with the syndrome of liver depression transforming into fire were often treated with Rehmanniae Radix， Gentianae Radix et Rhizoma， Gardeniae Fructus， Bupleuri Radix， and Scutellariae Radix. The commonly used herb pairs included Gentianae Radix et Rhizoma-Polygoni Multiflori Caulis， Polygoni Multiflori Caulis-Gardeniae Fructus， and Gentianae Radix et Rhizoma-Saposhnikoviae Radix， and the commonly used prescriptions were Longdan Xiegantang and Danzhi Xiaoyaosan. ConclusionThis study enriches the knowledge about neurodermatitis， clarifies the treatment principles and methods as well as the medication patterns， and provides a theoretical basis for clinical treatment and medication based on syndrome differentiation.

In Treatise on Cold Pathogenic and Miscellaneous Diseases,there are five articles concerning"diet as usual".When many doctors annotate such articles,they mostly interpret"diet as usual"as normal diet or because of stomach qi not affected by disease,ignoring the true significance of"diet as usual"and its role in clinical differential diagnosis.Through sorting out and summarizing the relevant provisions of"diet as usual",combining with the comments of Shuowen Jiezi and various ancient and modern doctors on the relevant provisions of"diet as usual"to explore the meaning behind it,the author believes that"diet as usual"can only be understood as"diet as before".Because it exists in a variety of diseases,it cannot be blindly extended to"normal diet"."Diet as usual"has two functions in clinical differential diagnosis:on the one hand,the stomach is empty,and no solid no drink blocks the qi movement,or there is stagnant heat in the stomach and intestines,but has not yet formed dry feces;on the other hand,when the middle jiao becomes one of the pathogenic factors of the disease,"diet as usual"can exclude the influence of the middle jiao.

AIM: To investigate the pathogenic bacteria, drug resistance, therapy and prognosis of infectious endophthalmitis secondary to different ophthalmic surgeries.METHODS:A retrospective analysis was conducted on the clinical data of 37 patients(37 eyes)with infectious endophthalmitis secondary to different ophthalmic surgeries. All these patients were treated in the Ophthalmology Department of Hebei General Hospital between January 2009 and June 2023. The pathogenic bacteria, drug resistance and therapeutic effects of early intravitreal injection of antibiotics or vitrectomy combined with silicone oil filling were analyzed.RESULTS:There were 24 eyes following cataract phacoemulsification combined with intraocular lens implantation, 4 eyes following vitrectomy, 2 eyes following combination surgery for glaucoma and cataract, 2 eyes following anti-glaucoma surgery, 2 eyes following corneal transplantation, 2 eyes following anterior chamber puncture, and 1 eye following intravitreal injection among the 37 eyes with infectious endophthalmitis. Totally 37 samples of intraocular fluid were submitted for bacterial and fungal culture, and 20 strains of pathogenic bacteria were identified, including 17 Gram-positive bacteria, 2 Gram-negative bacteria, 1 fusarium, and 12 cases were staphylococcus epidermidis. According to the final therapy, 7 eyes only treated by intravitreal injection, 11 eyes treated by intravitreal injection and vitrectomy, and 19 eyes only treated by vitrectomy. At the last follow-up, the best corrected visual acuity(BCVA)was ≤0.05 in 15 eyes, 0.06-0.3 in 15 eyes, and 0.4-1.0 in 7 eyes. Compared to before treatment(no light perception - hand movement in 31 eyes, counting fingers -0.05 in 3 eyes, 0.06-0.3 in 3 eyes), the difference was statistically significant(P<0.001).CONCLUSION: For infectious endophthalmitis patients with relatively mild ocular manifestation and good initial visual acuity, intravitreal injection of antibiotics remains an economically viable and effective therapy option. Early vitrectomy may effectively prevent the progression of infectious endophthalmitis, reduce the number of surgeries, and significantly improve the vision outcomes.

Objective: To explore the network structure characteristics and core items of rural middle school students suffering from campus bullying and anxiety symptoms, so as to provide a reference basis for the precise prevention and intervention of the comorbidity of campus bullying and anxiety symptoms. Methods: From September 2021 to March 2022, a multi stage random cluster sampling method was used to select 1 920 rural middle school students from Xuzhou. The Chinese version of the Olweus Bully/Victim Questionnaire was used to investigate the situation of campus bullying, and the Chinese version of the Generalized Anxiety Disorder (GAD-7) was used to assess anxiety symptoms. The network analysis method was used to construct the network between suffering from campus bullying and anxiety symptoms of rural middle school students to evaluate the centrality, bridge strength, stability and accuracy of each item. Results: The total score of suffering from campus bullying symptoms of rural middle school students was (10.42±3.26) points, and the total score of anxiety symptoms was (11.47±4.93) points. The symptom with the highest strength and expected influence was "unable to stop or control one s worry emotions", and the node strength and expected influence value was 1.041 7. The nodes "feel nervous, anxious or irritable" and "unable to stop or control one s worry emotions" were most closely related. The symptoms with the highest bridge strength were "others give me ugly nicknames to scold me or make fun of and satirize me" and "unable to stop or control one s worry emotions". Conclusions Rural middle school students suffering from campus bullying is related to anxiety symptoms. Accurate intervention according to the intervention targets may minimize the negative impact of suffering from campus bullying and anxiety symptoms on rural middle school students.

Objective To explore the current status of posttraumatic growth (PTG) among nurses at psychiatric department and analyze its latent profiles and population characteristics. Methods A total of 357 nurses from psychiatric departments of five tertiary Grade A hospitals were selected as the research subjects using the convenience sampling method. The PTG and professional quality of life were studied using the Posttraumatic Growth Inventory and the Chinese version of the Compassion Fatigue Scale. Results The PTG score of the nurses was (56.6±23.2). The scores of compassion satisfaction, burnout, and secondary traumatic stress among nurses were (32.6±7.2), (26.9±5.9), and (26.0±5.4), respectively. The result of potential profile analysis showed that the nurses could be divided into three latent profiles based on PTG levels: low PTG group (34.4%), moderate PTG group (44.0%), and high PTG group (21.6%). The results of multinomial logistic regression analysis showed that the nurses who slept 7-8 hours per day were at higher risk of being in the high PTG group compared with those who slept more than eight hours per day (P<0.05). Psychiatric nurses who took regular exercise were at higher risk of being in the high PTG group compared with those who took irregular exercise (P<0.05). The nurses who had high job satisfaction scores were at higher risk of being in the high PTG group compared with those who had low job satisfaction scores (P<0.01). The nurses with higher compassion satisfaction scores increased the risk of being in the high PTG group compared with those with lower compassion satisfaction scores (P<0.01). The nurses with higher burnout scores increased the risk of being in the low PTG group compared with those with lower burnout scores (P<0.01). Conclusion The PTG characteristics of the nurses exhibit heterogeneity and can be categorized into three distinct profiles. Sleep duration, regular exercise, job satisfaction, compassion satisfaction, and burnout are influencing factors for the PTG latent profiles of nurses working at psychiatric department.

Objective:To analyze the status quo of type D personality, intolerance of uncertainty and family support in first-episode stroke patients, and to explore the mediating role of family support between type D personality and intolerance of uncertainty in first-episode stroke patients, in order to provide reference for formulating relevant clinical intervention measures to promote the physical and mental health of first-episode stroke patients.Methods:This study was a cross-sectional investigation. A total of 300 patients with acute first-episode stroke who met the inclusion and exclusion criteria in the Department of Neurology of the General Hospital of Ningxia Medical University and the First People′s Hospital of Yinchuan from May 2023 to September 2023 were selected as the study objects by convenience sampling method. The general data questionnaire, Type D personality Scale-14, Family Caring Index Scale and the Intolerance of Uncertainty Scale were used to investigate them. Pearson correlation analysis was used to test the correlation between variables, and SPSS plug-in PROCESS 3.5 was used to test the mediation effect.Results:Finally, 300 questionnaires were effectively collected, including 228 males and 72 females. Patients aged ≥ 60 years old were the majority, accounting for 49.3% (148/300). The detection rate of type D personality in the first stroke patients was 37.3% (112/300), and the total score of Type D personality inventory, family support and intolerance of uncertainty of type D personality in the first stroke patients were (22.16 ± 9.95), (6.40 ± 2.23), (27.82 ± 7.93) points. The correlation analysis results showed that the intolerance of uncertainty of type D personality in the first stroke patients was positively correlated with type D personality scores ( r=0.675, P<0.001). There was a negative correlation with family support score ( r=-0.644, P<0.001). The results of mediating effect analysis showed that family support played a partial mediating role in the relationship between type D personality and intolerability of uncertainty in first-stroke patients, and the mediating effect accounted for 34.94% of the total effect. Conclusions:The mediating role of family support between type D personality and intolerability of uncertainty in first-stroke patients is established. In the future, the level of family support of patients can be continuously improved to reduce their intolerability of uncertainty, so as to promote the physical and mental health of patients and improve their quality of life.
