Objective:To study the correlation between hair fluorine level and hypertension of permanent residents in high altitude areas of Tibet Autonomous Region (Tibet).Methods:A random cluster sampling method was used to select 5 villages in the high altitude areas of Tibet from June to August 2021 and June to August 2022, respectively, and questionnaire survey, physical examination, and biochemical indicator testing were conducted on permanent Tibetan residents in the above mentioned villages. At the same time, hair samples were collected, the hair fluorine level was determined by ion selective electrode method, and the correlation between various indicators and hair fluorine level and hypertension was analyzed.Results:A total of 227 individuals were included, with hair fluorine level of (15.06 ± 0.16) mg/kg. Correlation analysis showed that there was no correlation between the study subjects' systolic blood pressure, diastolic blood pressure, body mass index, pulse, neck circumference, chest circumference, uric acid level and hair fluorine level ( P > 0.05). Abdominal circumference, hip circumference, and hemoglobin level were positively correlated with hair fluorine level ( r = 0.23, 0.14, 0.29, P < 0.05), while blood glucose level and finger pulse oxygen were negatively correlated with hair fluorine level ( r = - 0.23, - 0.24, P < 0.001). Binary logistic regression analysis showed that age ( OR = 1.04, 95% CI: 1.01 - 1.06), chest circumference ( OR = 1.10, 95% CI: 1.01 - 1.20), and hair fluorine level ( OR = 1.22, 95% CI: 1.02 - 1.46) had an impact on hypertension ( P < 0.05). Conclusion:There is a certain correlation between hair fluoride level and hypertension in the population of high altitude areas in Tibet.

Sodium valproate (VPA) is a widely used antiepileptic drug and mood stabilizer in both neurology and psychiatry. Valproate-induced hyperammonemic encephalopathy (VHE) is a rare but serious complication associated with its use. This paper reports a clinical case of a patient with bipolar disorder who developed VHE after self-administering, a rapid short-term dose escalation of VPA. The patient exhibited symptoms including nausea, vomiting, altered consciousness, and disorientation shortly after the dosage increase. Following prompt discontinuation of VPA and symptomatic treatment including cathartic therapy to promote drug elimination, the patient gradually regained consciousness and physical symptoms resolved. Through a review of this case and relevant literature, this article discusses the pathophysiological mechanisms, clinical manifestations, diagnosis, and treatment of VHE, to provide clinical reference for healthcare professionals.

Background::Breast cancer is ranked among the most prevalent malignancies in the Chinese female population. However, comprehensive reports detailing the latest epidemiological data and attributable disease burden have not been extensively documented.Methods::In 2018, high-quality cancer surveillance data were recorded in 700 population-based cancer registries in China. We extracted data on female breast cancers (International Classification of Diseases, Tenth Revision [ICD-10]: C50) and estimated the incidence and mortality in 2022 according to the baseline data and corresponding trends from 2010 to 2018. Pathological types were classified according to the ICD for Oncology, 3rd Edition codes. Disability-adjusted life years (DALYs) were calculated as the sum of the years of life lost (YLLs) and years lived with disability (YLDs).Results::In 2022, approximately 357,200 new female breast cancer cases and 75,000 deaths occurred in China, accounting for 15.59% and 7.94% of total new cancer cases and deaths, respectively. The age-standardized incidence rate (ASIR) was 33.04 per 100,000. When analyzed by pathological type, the ASIRs for papillary neoplasms, invasive breast carcinoma, rare and salivary gland-type tumors, and other types were 1.13, 29.79, 0.24, and 1.88 per 100,000, respectively. The age-standardized mortality rate (ASMR) was 6.10 per 100,000. A total of 2,628,000 DALYs were found to be attributable to female breast cancer in China, comprising 2,278,300 YLLs and 349,700 YLDs. The ASIR, ASMR, and age-standardized rate (ASR) for DALYs in urban areas were consistently higher than those in rural areas. We observed a four-fold increase in the ASIR and ASR for DALYs and an eight-fold increase in the ASMR among females over 55 years compared with those aged under 55 years.Conclusion::These data provide invaluable insights into the latest epidemiology of female breast cancer in China and highlight the urgency for disease prevention and control strategy formulation.

Objective To find out the social competence level of school-age children with speech sound disorders after cleft palate operation and functional speech sound disorders.Methods Thirty-four school-age children with postoperative cleft palate speech sound disorders and thirty-seven school-age children with functional speech sound disorders attending a specialty clinic for the diagnosis and treatment of childhood speech and language disorders in 2023 were selected,and 32 age-and gender-matched normal children in a local elementary school were also randomly selected as the normal group.The Achenbach Child Behavior Checklist was used to assess the so-cial competence of the three groups of children and a cross-sectional study was conducted.Results Children with cleft palate speech sound disorders and functional speech sound disorders had lower scores on activity,communication and academic ability,with specific manifestations varying in different gender groups,but there was no significant difference in scores between the two groups.In contrast,the activity and communication scores of the functional speech sound disordergroup were significantly lower than those of the normal group(P＜0.05).Conclusion School-age children with cleft palate speech sound disorders and functional speech sound disorders are at a higher risk of difficulties in social functioning,in terms of activity,communication and academic ability,whereas speech sound disorders may be one of the most important influencing factors of such difficulties and cleft palate does not have an additional impact on the social competence level of the child.

Purpose To investigate the diagnostic value of 18F-FDOPA PET/CT imaging and semi-quantitative analysis platform for the diagnosis of Parkinson's disease(PD).Materials and Methods There were 27 healthy controls and 56 clinically diagnosed PD patients,including 33 early PD(Hoehn-Yahr class Ⅰ-Ⅱ)and 23 advanced PD(Hoehn-Yahr class Ⅲ-Ⅳ),underwent 18F-FDOPA PET imaging in Nanjing First Hospital,Nanjing Medical University were consecutively enrolled from January 2018 to December 2019.The striatal to occipital ratio(SORs)in radioactivity was calculated by HERMES BRASS platform,thereby completing the semi-quantitative analysis of the brain based on regions of interest and observing the asymmetry of the striatal subregions in early-stage PD and late-stage PD patients.Using artificial intelligence techniques to perform principal component analysis on the SORs of the striatal subregions in PD group and healthy control group,the degree of data aggregation and the distinguishability between groups were observed.Results The SORs was significantly reduced in the whole caudate,anterior,posterior putamen and striatum of advanced PD patients(t=9.02-11.72,P<0.000 1).The area under the curve was 0.952,0.973,0.995 and 0.982,respectively.Compared with the healthy control group,the loss of striatal asymmetry index(mean)in each subregion of the striatum in early PD group was caudate(7.61±5.50)%,anterior putamen(11.43±8.97)%,posterior putamen(17.17±11.63)%,and whole striatum(10.65±7.46)%,respectively.The uptake of 18F-FDOPA in the striatum of PD patients was significantly reduced,and the most obvious loss of early PD patients was contralateral posterior putamen,with a decrease of 34%.Conclusion The platform semi-quantitative analysis of 18F-FDOPA PET/CT images provides objective semi-quantitative values for early diagnosis and differential diagnosis of PD.Asymmetry in the striatum,especially in the putamen,may be an important parameter for early diagnosis of PD..

Objective:Partial stereotactic ablative boost radiotherapy(P-SABR)is a method to deliver SABR boost to the gross tumor boost volume(GTVb), followed by conventionally fractionated radiotherapy to the whole tumor area(GTV). GTVb is the max volume receiving SABR while ensuring the critical organ-at-risk(OAR)falloff to 3 GyE/f. We investigated the potential advantage of proton therapy in treating bulky non-small cell lung cancer(the tumor length greater than 8 cm).Methods:Nine patients with bulky NSCLC treated with photon P-SABR in our institute were selected. For the treatment planning of proton therapy, the GTVb target area was gradually outwardly expanded based on the photon GTVb target area until the dose to critical OARs reached 3 GyE/f. The GTV and CTV areas remained the same as photon plan. A proton intensity-modulated radiation treatment plan(proton-IMPT), a photon intensity-modulated radiation treatment plan(photon-IMRT)and a photon volumetric modulated arc therapy(photon-VMAT)were created for each patient, respectively. The dosimetric parameters of different treatment plans were compared.Results:The volume ratio of GTVb-photon and GTVb-proton to GTV was(25.4±13.4)% and(69.7±30.0)%,respectively( P<0.001). In photon-IMRT, photon-VMAT, and proton-IMPT plan groups, the mean dose of CTV was(76.1±4.9)Gy, (78.2±3.6)Gy, and(84.7±4.9)Gy, respectively; the ratio of tumor volume with Biologic Effective Dose(BED)≥ 90 Gy to GTV volume was(70.7±21.7)%, (76.8±22.1)%,and(97.9±4.0)%,respectively. The actual dose and BED to the tumor area of the proton-IMPT plan group were significantly higher than those of the photon plan group(both P<0.05). Besides, the OARs dose was significantly decreased in the proton-IMPT group, with(49.2±22.0)%, (56.8±19.0)% and(16.1±6.3)% of the whole lung V5 for photon-IMRT, photon-VMAT and proton-IMPT, respectively(all P<0.001). Conclusions:Larger GTV boost target volume, higher BED and reduced OARs dose can be achieved in proton plans compared with photon plans. Proton P-SABR is expected to further improve the local control rate of bulky NSCLC with fewer adverse effects.
