A 20-year-old male patient presented to the Department of Dermatology of Peking Union Medical College Hospital with complaints of an 8-year history of facial scarring, swelling of the lower limbs, and a 4-year history of scalp thickening. Physical examination showed thickening furrowing wrinkling of the skin on the face and behind the ears, ciliary body hirsutism, blepharoptosis, and cutis verticis gyrate. Both lower limbs were swollen, especially the knees and ankles. The skin of the palms and soles of the feet was keratinized and thickened. Laboratory examination using bone and joint X-ray showed periostosis of the proximal middle phalanges and metacarpals of both hands, distal ulna and radius, tibia and fibula, distal femurs, and metatarsals.Genetic testing revealed two variants in SLCO2A1, c.1658T > A and c.96+4A > C.Through multidisciplinary consultation, we confirmed the diagnosis of pachydermoperiostosis.

Wilson disease is a copper metabolism disorder caused by mutations in the ATP7B gene， which encodes a copper-transporting ATPase β， and can result in multisystem damage. The kidneys are the third most commonly affected organs after the liver and brain. In recent years， numerous diagnostic and treatment guidelines for Wilson disease have emerged. However， most of these focus primarily on hepatic and neurological manifestations and their management， with limited coverage of renal involvement. The high incidence， low awareness， and lack of clinical specificity of Wilson disease-related renal damage （WDRD） have made early detection and intervention particularly challenging in clinical practice. To further optimize the treatment of patients with WDRD， improve clinical diagnosis and management， and enhance patients' quality of life， the Neurology Committee of the Chinese Association of Integrative Medicine， in April 2024， initiated a revision of the first expert consensus on the integrated diagnosis， treatment， and management of WDRD. This effort brought together experts in hepatology， encephalopathy （neurology）， and nephrology from many tertiary-level grade A hospitals and research institutions across China. Through comprehensive literature review and integration of frontline clinical experience， the expert group jointly developed Chinese Expert Consensus on Integrated Chinese and Western Medicine Management of Wilson Disease-related Renal Damage （hereinafter referred to as the "Consensus"）. This article provides a detailed interpretation of the Consensus in terms of diagnostic criteria， traditional Chinese medicine （TCM） syndrome differentiation and treatment classification， and comprehensive disease management， aiming to better guide clinical application. Regarding diagnostic criteria， the Consensus integrates the latest standards in China and abroad， highlights the importance of biochemical diagnosis， and compensates for the limitations of genetic testing. In the area of TCM syndrome differentiation and treatment， the Consensus refines four major syndrome types， introduces a newly defined syndrome， i.e.， phlegm， blood stasis， and heat accumulation， and elaborates on treatment principles， prescriptions， and clinical modification rules for each syndrome. For comprehensive disease management， the Consensus emphasizes multi-dimensional intervention strategies， including diet， exercise， emotional regulation， medication， and medical care， with the goal of maximally controlling the progression of renal dysfunction and helping patients achieve a better quality of life.

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.

ObjectiveTo analyze the fertility characteristics of the registered population in a neighborhood in Jing’an District， Shanghai from 2013 to 2022， and to provide a reference for population development planning and allocation of public health resources. MethodsData on newborns and puerperae registered in the neighborhood were collected through the Shanghai Birth Medical Information System and Public Security Department information system. Statistical analysis was conducted using Excel 2010， and the Joinpoint regression model was used to describe the changes. ResultsFrom 2013 to 2022， the crude birth rate， general fertility rate， and total fertility rate showed a declining trend， with average annual percent change （AAPC） values of -7.62%， -6.99%， and -4.54%， respectively. The average age of first childbirth and the age of childbearing among women gradually increased， with AAPC values of 1.24% and 1.28%， respectively. In the past 10 years， the total number of newborns showed a downward trend， with an AAPC value of -6.15%. After the implementation of the two-child policy， the proportion of second children showed an increasing trend， with an AAPC value of 7.37%. ConclusionThe fertility level of the population in the neighborhood is declining. The two-child policy has not significantly improved fertility rates， and the age of childbearing in women continues to rise. Diverse measures are needed to encourage childbirths and promote healthy births.

Eleven compounds were isolated and purified from the ethyl acetate part of 80% ethanol extract of Ferula feruloides root by a combination of normal-phase silica gel column chromatography, Sephadex LH-20 dextran gel column chromatography and semi-preparative liquid chromatography and then modern wave spectrometry methods (NMR, MS, UV, IR) were used to identify the structures of the compounds, which were identified as baigene D (1), baigene E (2), baigene F (3), β-kirialovin (4), α-kirialovin (5), falcarindiol (6), ammoresinol (7), dshamirone (8), 2,3-dihydro-7-hydroxy-2S*,3R*-dimethyl-3-[4-methyl-5-(4-methy1-2-furyl)-3(E)-pentenyl]-furo[3,2-c]coumarin (9), 2,3-dihydro-7-hydroxy-2S*,3R*-dimethyl-2-[4,8-dimethyl-3(E),7-nonadi-enyl]-furo[3,2-c]coumarin (10), and baigene C (11). Compounds 1-3 are new coumarin analogues, and compounds 4-6 are firstly isolated from F. feruloides.

Objective:To compare the difference between the Evidence Quality Grading System for Public Health Decision-making(PHE-Grading)and the Grading of Recommendations Assessment,Development and Evaluation(GRADE)System in evaluating the quality of evidence for public health decision-making.Methods:Systematic reviews about topic"Public health"were electronically searched in the Cochrane Library database from inception to February 27,2024.EndNote 20 software was used for literature screening,Excel 2021 and SPSS 22.0 software were used for data collation and analysis,and the forest plot was drawn by RevMan 5.4.1 software.Results:A total of 61 systematic reviews were finally included for evidence quality evaluation.The forest plot of GRADE and PHE-Grading evidence grading results showed that high grade[OR:2.39,95%CI(1.21 to 4.75)],moderate grade[OR:0.40,95%CI(0.31 to 0.52)],low grade[OR:0.37,95%CI(0.29 to 0.46)],and extremely low grade[OR:85.11,95%CI(34.80 to 208.11)],and the differences in evidence quality grading results between the two systems were statistically significant.Conclusions:Compared with GRADE,PHE-Grading may be more accurate in grasping the certainty of public health decision-making evidence.Currently,the quality of public health decision-making evidence is still concentrated in low and middle level,and high-quality research still needs to be strengthened to support scientific decision-making.

Objective:To investigate the clinicopathologic features of sarcomatoid carcinoma of the pancreas.Methods:The clinicopathological data of 7 cases with sarcomatoid carcinoma of the pancreas admitted in the Affiliated Lihuili Hospital of Ningbo University from September 2013 to August 2021 were retrospectively analyzed, including clinical manifestations, laboratory examination, imaging examination, pathological examination of tissue specimens, surgical methods and adjuvant treatments. Expressions of mesenchymal markers and epithelial markers in tumor tissues were determined by immunohistochemical staining.Results:Among the 7 cases of sarcomatoid carcinoma of the pancreas, there were 4 male and 3 female. The patient age ranged from 51 to 88 years old, and the mean age was 69 years old. All the patients underwent CT examimation before surgery. 3 tumors were located in the head, 3 in the body and 1 in the tail of the pancreas. CT examination also showed that 4 tumors were cystic solid and 3 were cystic. Six patients underwent radical surgery and one underwent partial resection for biopsy. Microscopically, the tumor was predominantly composed of sarcomatoid spindle-shaped cells. Immunohistochemical staining showed that the tumor expressed both mesenchymal markers vimentin and epithelial marker CK7, CK19, CK(pan) and CAM5.2. The overall prognosis of the patients was poor, 4 cases died within 1 year after surgery, and the other 3 cases survived without recurrence.Conclusions:The clinical manifestations of sarcomatoid carcinoma of the pancreas were not typical, but the pathological and immunohistochemical features are obvious and the prognosis is poor.

Purpose::To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.Methods::A total of 282 healthy young male volunteers aged 18 -20 years participated in this cohort study. Injury location, degree, and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries. The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly. The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5, 50, 100 and 200 kHz to obtain 4 impedance values. The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution. Data of normal distribution were shown as mean ± SD and analyzed by t-test, while those of non-normal distribution were shown as median (Q 1, Q 3) and analyzed by Wilcoxon rank sum test. The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy. Results::Among the 282 subjects, 78 (27.7%) developed training injuries. Lower extremity training injuries revealed the highest incidence, accounting for 23.4% (66 cases). These patients showed higher percentages of lean body mass ( p = 0.001), total body water (TBW, p=0.006), extracellular water ( p=0.020) and intracellular water ( p=0.010) as well as a larger ratio of basal metabolic rate/total weight ( p=0.006), compared with those without lower extremity muscle injuries. On the contrary, the percentage of body fat ( p=0.001) and body fat mass index ( p=0.002) were lower. Logistic regression analysis showed that TBW percentage > 65.35% ( p=0.050, odds ratio =3.114) and 3rd space water > 0.95% ( p=0.045, odds ratio =2.342) were independent risk factors for lower extremity muscle injuries. Conclusion::TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower extremity muscle injuries in young males following training.

Objective To explore the effects of low-dose esketamine on the median effective dose(ED50)of ciprofol for sedation in elderly patients undergoing ultrasound-guided transperineal prostate biopsy.Methods Forty-nine elderly male patients,aged 65-75 years,BMI 18.5-30.0 kg/m2,ASA physical stutas Ⅰ-Ⅲ,who underwent ultrasound-guided transperineal prostate biopsy,were randomly as-signed into the esketamine-ciprofol group(group E,n=23)and the ciprofol group(group C,n=26).After intravenous administration of sufentanil 0.1 μg/kg,patients in group E received esketamine 0.2 mg/kg,while patients in group C received the same volume of normal saline.The up-and-down sequential allocation method was used to calculate the effective dose of ciprofol.The initial dose of ciprofol was 0.2 mg/kg in group E and 0.3 mg/kg in group C,and the dose gradient was 0.05 mg/kg for both groups.If there was no body movement during the first puncture of prostate after the loss of eyelash reflex,the ciprofol dose in the next patient was reduced by 0.05 mg/kg.Otherwise,the ciprofol dose in the next patient was in-creased by 0.05 mg/kg.The study was completed until 7 inflection points alternating between non-body movement and body movement achieved.The total amount of ciprofol,surgical time,recovery time,stay in recovery room,hypotension,bradycardia,respiratory depression,injection pain,nausea and vomiting,and adverse reaction of the mental system were recorded.The Probit method was used to calculate the ED50 and 95%effective dose(ED95)with 95%confidence interval(CI)of ciprofol for inhibition of body movement.Results Compared with group C,the total amount of ciprofol in group E was significantly reduced(P＜0.05).There were no significant differences between the two groups in surgical time,recovery time,stay in recovery room,and adverse events.The ED50 of ciprofol in group E was 0.22 mg/kg(95%CI 0.19-0.26 mg/kg),and the ED50 in group C was 0.38 mg/kg(95%CI 0.31-0.46 mg/kg).Compared with group C,the ED50 in group E was significantly reduced(P＜0.05).The ED95 of ciprofol in group E was 0.28 mg/kg(95%CI 0.25-0.49 mg/kg),and the ED95 in group C was 0.51 mg/kg(95%CI 0.44-1.25 mg/kg).Compared with group C,the ED95 in group E was significantly reduced(P＜0.05).Conclusion The ED50 of ciprofol for inhibition of body movement in elderly patients undergoing ultrasound-guided transperi-neal prostate biopsy was 0.38 mg/kg,which was reduced to 0.22 mg/kg by using lose-dose esketamine 0.2 mg/kg as an adjuvant.
