Objective:To assess the efficacy of "three-step" strategy for preparing autologous pedicled nasal mucosal flaps in repairing cerebrospinal fluid（CSF） leaks following transsphenoidal pituitary adenoma surgery. Methods:A retrospective study was conducted on the clinical data of 25 patients who developed CSF leaks after transsphenoidal pituitary adenoma surgery at the First Affiliated Hospital of Kunming Medical University between July 2012 and June 2022. Surgical repair was selected step by step using nasal septal mucosal flap with either the posterior septal artery or septal branch of the sphenopalatine artery as the pedicle, or a pedicled middle turbinate mucosal flap. All patients underwent ≥2-year endoscopic follow-up to assess flap viability and CSF leak recurrence. Results:The median postoperative hospital stay was 4 days. Five patients developed intracranial infections postoperatively. The follow-up period ranged from 2 to 12 years. Nasal endoscopic examinations showed good mucosal flap growth, with no recurrence of CSF leakage in any of the patients. Conclusion:High-flow cerebrospinal fluid（CSF） leaks following pituitary tumor surgery pose significant challenges for clinical repair. Based on intraoperative nasal septal mucosal preservation and the condition of sellar base CSF leakage, the "three-step" strategy for preparing autologous pedicled nasal mucosal flaps-utilizing posterior septal artery, ethmoidal artery-based, or pedicled middle turbinate mucosal flaps sequentially-is a safe and effective repair method.

Nigella sativa L. seeds have been traditionally utilized in Chinese folk medicine for centuries to treat vitiligo. This study revealed that the ethanolic extract of Nigella sativa L. (HZC) enhances melanogenesis and mitigates oxidative stress-induced cellular senescence and dysfunction in melanocytes. In accordance with established protocols, the ethanol fraction from Nigella sativa L. seeds was extracted, concentrated, and lyophilized to evaluate its herbal effects via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays, tyrosinase activity evaluation, measurement of cellular melanin contents, scratch assays, senescence-associated β-galactosidase (SA-β-gal) staining, enzyme-linked immunosorbent assay (ELISA), and Western blot analysis for expression profiling of experimentally relevant proteins. The results indicated that HZC significantly enhanced tyrosinase activity and melanin content while notably increasing the protein expression levels of Tyr, Mitf, and gp100 in B16F10 cells. Furthermore, HZC effectively mitigated oxidative stress-induced cellular senescence, improved melanocyte condition, and rectified various functional impairments associated with melanocyte dysfunction. These findings suggest that HZC increases melanin synthesis in melanocytes through the activation of the MAPK, PKA, and Wnt signaling pathways. In addition, HZC attenuates oxidative damage induced by H₂O₂ therapy by activating the nuclear factor E2-related factor 2-antioxidant response element (Nrf2-ARE) pathway and enhancing the activity of downstream antioxidant enzymes, thus preventing premature senescence and dysfunction in melanocytes.

Objective:To investigate the current situation of key endemic disease prevention and control in Shanxi Province, and provide a scientific basis for further strengthening the implementation of prevention and control measures.Methods:In 2021, monitoring of key endemic disease prevention and control projects in Shanxi Province was carried out in accordance with the current national monitoring plans for iodine deficiency disorders and water source high iodine areas, for endemic fluorosis, endemic arsenic poisoning, Kashin-Beck disease, and Keshan disease. The effect of prevention and control measures was evaluated in accordance with the "Evaluation Measures for Key Endemic Disease Control and Elimination (2019 Edition)". Patient management services and treatment subsidy projects were carried out in accordance with the "Management Service Standards for Endemic Disease Patients" and the "Management Measures for Treatment of Endemic Disease Patients".Results:All 117 counties (cities, districts, hereinafter referred to as counties) in Shanxi Province had reached the national elimination standards for iodine deficiency disorders, and the overall iodine nutrition of the population was generally suitable. However, the consumption rate of qualified iodine salt in 8 counties was ≤90%, and the iodine nutrition of pregnant women in 13 counties was insufficient. The water improvement rate in 295 villages in 12 counties across the province with high water iodine level was 80.68% (238/295), and the proportion of villages with qualified water iodine after water improvement was 38.31% (113/295). The prevention and control measures of 93.55% (58/62) of the counties in the province with endemic fluorosis caused through drinking water reached the national control standards. Totally 20 counties ravaged by coal-burning borne endemic fluorosis, 16 counties ravaged by drinking water borne endemic arsenicosis (high arsenic areas), 35 counties ravaged by Kashin-Beck disease, and 11 counties ravaged by Keshan disease met the national elimination standards. In 2021, 11 197 patients with endemic diseases were followed up and managed in Shanxi Province, and drug treatment programs were carried out on 3 413 patients with skeletal fluorosis, 2 088 patients with Kashin-Beck disease, and 10 patients with chronic Keshan disease.Conclusions:The overall prevention and control of key endemic diseases in Shanxi Province remains under control or elimination. However, the water improvement in some drinking water borne endemic fluorosis areas still needs to be further strengthened. Measures for water improvement and supply of non-iodized salt in water source high iodine areas still need to be coordinated and promoted. Key endemic disease patients in Shanxi Province have basically achieved standardized management.

AIM:To investigate the molecular mechanisms of KG-1 cell proliferation by profiling its responses to various protein kinase inhibitors.METHODS:CCK-8 assay,real time quantitative PCR(qRT-PCR)and Western-blot were used to detect the effect of various protein kinase inhibitors on KG-1 cell proliferation,the expression levels of mRNA and phosphorylation level of signaling pro-teins in the FGFR1 downstream pathways.RE-SULTS:NVP-BGJ398 and PD173074 effectively in-hibited the proliferation of KG-1 cells,indicative of a crucial role of FGFR downstream signaling.After treatment with FGFR inhibitors,the levels of p-FG-FR1OP2-FGFR1 and p-STAT5 decreased significantly(P<0.001),p-AKT decreased slightly(P<0.05),with-out affecting the p-ERK level(P>0.05).CONCLU-SION:FGFR1OP2-FGFR1 mainly acts on the down-stream STAT5 signaling pathway to promote cell proliferation.Comprehensive protein kinase inhibi-tion analysis is a reliable and direct approach to identify functional drivers of cancer cell prolifera-tion.

Objective:To investigate the prevalence of thyroid disease in adults in different water iodine areas and to explore the association between iodine and thyroid disease.Methods:In May of 2016, using cross-sectional survey, Gaoche Village and Maxi Village of Wenshui County were selected in Shanxi Province as a high-iodine area and a low-iodine area, respectively, Xiwenzhuang Village of Taiyuan City as an appropriate-iodine area. Questionnaire surveys, urinary iodine levels, thyroid ultrasound, determination of thyroid function and autoantibody were conducted for permanent residents aged 18 - 65.Results:A total of 898 people were investigated, including 288 in high-iodine area, 324 in low-iodine area and 286 in appropriate-iodine area. The medians urinary iodine were 417.8, 126.6 and 216.5 μg/L in high, low and appropriate-iodine areas, respectively, and the difference was statistically significant ( H = 288.61, P < 0.05). After age and sex standardization, the detection rates of hyperthyroidism in low, appropriate and high-iodine areas were 0.27%, 1.06% and 1.43%, respectively. The detection rates of sub-clinical hyperthyroidism were 0.57%, 0.31% and 0.30%, respectively. The detection rates of hypothyroidism were 1.45%, 1.15% and 1.85%, respectively. The detection rates of sub-clinical hypothyroidism were 19.34%, 28.50% and 32.76%, respectively. The detection rates of thyroid nodule were 20.51%, 20.17% and 33.78%, respectively. The positive rates of anti-thyroglobulin antibodies (TgAb) were 18.13%, 19.41% and 11.99%, respectively. The positive rates of thyroid peroxidase antibody (TPOAb) were 9.25%, 12.04% and 8.97%, respectively. The appropriate-iodine area was used as control, logistic regression analysis showed that only the detection rate of thyroid nodule in high-iodine area was significantly higher than that in appropriate-iodine area [odds ratio ( OR) = 0.488 5, 95% confidence interval ( CI) = 0.327 2 - 0.729 2 , P < 0.05]. Conclusion:In Shanxi Province, the detection rate of thyroid nodules is different in different areas of water iodine, and the detection rate of thyroid nodule in adults in high-iodine area is higher than that in other areas.

Objective:To learn about the status of iodine deficiency disorders (IDD) and iodine nutrition of residents in Shanxi Province since the implementation of the standard of "Iodine Content in Edible Salt" (GB 26878-2011), to evaluate the level of prevention and control of IDD, and to provide scientific basis for adjusting prevention and control strategies.Methods:The data of core indicators monitored by Shanxi Province in accordance with the requirements of the national iodized salt and IDD monitoring program for each year from 2012 to 2021 were comprehensively reviewed, and the change trends of the indicators such as coverage rate of iodized salt, consumption rate of qualified iodized salt, children's median urinary iodine and goiter rate, and pregnant women's median urinary iodine were analyzed; the evaluation of IDD elimination in counties (cities and districts, hereinafter referred to as counties) was analyzed.Results:From 2012 to 2021, the coverage rate of iodized salt in Shanxi Province was remained > 95%; from 2012 to 2014 (transition period between new and old standard iodized salt), the consumption rate of qualified iodized salt had an upward trend (χ 2trend = 2 703.32, P < 0.001), with a downward trend from 2015 to 2017 (before and after the reform of the salt industry system, χ 2trend = 122.18, P < 0.001), and with an upward trend from 2018 to 2021 (after the reform of the salt industry system, χ 2trend = 455.11, P < 0.001), from 2018, the consumption rate of qualified iodized salt remained > 90%; from 2015 to 2021, the average content of salt iodine was between 23 - 25 mg/kg, and the coefficient of variation of salt iodine was 15% - 18%. From 2014 to 2021, the median urinary iodine of children in Shanxi Province remained at 200 - 250 μg/L, the median urinary iodine of pregnant women remained at 150 - 200 μg/L, and the goiter rate of children remained below 5%. Every year, iodine nutrition of pregnant women in some counties was insufficient. In 2016, the proportion of counties with insufficient iodine nutrition of pregnant women was high, reached 30.0% (12/40); from 2018 to 2021, the proportion of counties with insufficient iodine nutrition of pregnant women had a downward trend (χ 2trend = 9.37, P = 0.002), which was 11.1% (13/117) in 2021. In 2020, 117 counties in the province reached the IDD elimination standard, with a compliance rate of 100.0%. Conclusions:Since the implementation of the current salt iodine content standard for 10 years, the consumption rate of qualified iodized salt has gradually stabilized and remained at a high level, which can ensure that IDD is in a sustainable state of elimination in Shanxi Province, and the iodine nutrition of school-age children and pregnant women is generally at a suitable level. However, there are a certain number of counties with insufficient iodine nutrition of pregnant women. It is recommended to guide pregnant women to supplement iodine or set the average standard of salt iodine for pregnant women separately.

Objective:To study the relationship between thyroid volume (TV) and thyroid autoantibodies in patients with autoimmune thyroid disease (AITD), and to explore the factors affecting goiter in patients with AITD.Methods:The newly diagnosed AITD adult patients in the Affiliated Hospital of Shanxi Institute for Endemic Disease Prevention and Control from November 2019 to October 2020 were selected for questionnaire survey, physical examination, thyroid function and thyroid autoantibody test, determination of serum iodine content and thyroid ultrasound, and the correlation between thyroid volume and thyroid autoantibody was analyzed.Results:A total of 147 newly diagnosed adult AITD patients were included, including 63 cases of Graves' disease (GD, 30 males and 33 females) and 84 cases of chronic lymphocytic thyroiditis (HT, 29 males and 55 females). The TV of male and female patients with GD was positively correlated with the levels of thyrotropin receptor antibody (TRAb) ( rmen = 0.515, rwomen = 0.412, P < 0.05). The TV of male and female patients with HT was not correlated with the levels of thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb, rmen = - 0.137, 0.168, rwomen = 0.184, - 0.088, P > 0.05). There were no correlation between TPOAb levels and TGAb levels in male and female HT patients ( rmen = 0.153, rwomen = 0.102, P > 0.05). The TV of male and female patients with GD or HT was not correlated with the serum levels of iodine ( rmen = 0.230, 0.013, rwomen = 0.096, 0.069, P > 0.05). Conclusion:TRAb level is positively correlated with the TV in GD patients.

Objective:To master the prevalence of thyroid nodule in adults in different water iodine areas and to explore the association between high iodine intake through drinking water and thyroid nodule prevalence.Methods:Xiwenzhuang Village of Taiyuan City was selected as iodine-adequate area, and Gaoche Village and Maxi Village of Wenshui County as high-iodine area and low-iodine area, respectively, in Shanxi Province. Questionnaire surveys were conducted, thyroid ultrasound was used and urinary iodine levels were determined of residents aged 18 to 65 years. Analysis of the prevalence of thyroid nodules in adults in different wated iodine areas.Results:A total of 868 person were investigated, including 286 in high-iodine area, 270 in iodine-adequate area and 312 in low-iodine area. The medians urinary iodine in high, adequate and low iodine areas were 418.7, 218.5 and 127.1 μg/L, respectively, and the differences were statistically significant ( H = 289.70, P < 0.05). The detection rate of thyroid nodule in adults with high, adequate and low iodine levels were 31.1% (89/286), 27.4% (74/270) and 19.2% (60/312), respectively, the differences were significant statistically among three groups (χ 2 = 11.65, P < 0.05). The detection rates of solitary nodule in adults were 17.8% (51/286), 14.1% (38/270), and 13.1% (41/312), respectively, the differences were not significant statistically among the three groups (χ 2 = 2.83, P > 0.05). The detection rate of multiple nodules in adults were 13.3% (38/286), 13.3% (36/270), and 6.1% (19/312), respectively, the differences were significant statistically among the three groups (χ 2 = 10.89, P < 0.05) high-iodine area and iodine-adequate area have higher detection rates than low-iodine area ( P < 0.05). The thyroid nodules were mainly the cyst nodules in high-iodine area. Conclusions:The detection rate of thyroid nodule in adults is the lowest in adequate iodine nutrition level. More iodine intake is probably a risk factor for thyroid multiple nodules.

Objective To understand the iodine nutritional status and thyroid function of different populations after 20 years of universal salt iodization in iodine deficiency area of Shanxi Province, and to provide data support for scientific iodine supplementation according to local conditions. Methods In 2014, six townships (Chengguan, Dadeng, Dengzhuang, Gucheng, Xiangling and Fencheng townships) in Xiangfen County, Linfen City, Shanxi Province, were selected as the place of investigation. Four hundred school-age children aged 6 - 12 years (school-age children), 400 child-bearing women aged 18 - 44 (child-bearing women), 400 pregnant women, 400 lactating women and their 0 - 6 months breast-feeding infants (breast-feeding infants), and 400 children aged 7 -24 months were selected by two-stage sampling method. Water samples of school-age children's domestic drinking water and salt samples for domestic consumption were collected, and the water iodine and salt iodine were detected by arsenic and cerium catalytic spectrophotometry ( recommended by the National Iodine Deficiency Disorders Reference Laboratory) and "General Test Method in Salt Industry-Determination of Iodine" (GB/T 13025.7-2012). Random urine samples of all subjects were collected, urine iodine was detected by "Method for Determination of Iodine in Urine by As3+-Ce4+ Catalytic Spectrophotometry" ( WS/T 107-2006 ) . Samples of filter paper dried blood spots (DBS) of school-age children, child-bearing women, pregnant women, lactating women and breast-feeding infants were collected, and serum total thyroxine (TT4) and thyroid stimulating hormone (TSH) levels were detected by time-resolved fluorescence immunoassay. Results A total of 290 water samples were collected, and the median of water iodine was 9.37μg/L. A total of 406 salt samples were collected, the median of salt iodine was 25.0 mg/kg, the coverage rate of iodized salt was 98.52％ (400/406), and the consumption rate of qualified iodized salt was 92.61％ (376/406). Urine samples of 389 school-age children, 379 child-bearing women, 363 pregnant women, 365 lactating women, 366 breast-feeding infants, and 366 children aged 7 - 24 months were collected, and the medians of urine iodine were 200.7, 175.0, 186.0, 113.2, 285.8 and 204.8 μg/L, respectively. Among them, school-age children, breast-feeding infants, and children aged 7-24 months were over the appropriate level, while the rest populations were at the iodine appropriate levels. Blood samples of 402 school-age children, 397 child-bearing women, 398 pregnant women, 390 lactating women, and 386 breast-feeding infants were collected, and the medians of TT4 were 127.2, 110.2, 141.7, 95.8 and 139.0 nmol/L, respectively; the medians of TSH were 1.2, 0.9, 0.8, 0.9 and 0.9 mU/L, respectively, and they were all within the reference ranges. The abnormal rates of TT4 (8.46％, 33/390) and TSH (7.95％, 31/390) in lactating women were higher than those in school-age children, child-bearing women, pregnant women and breast-feeding infants [TT4 abnormal rates were 0.25％(1/402), 1.26％ (5/397), 0.50％ (2/398), 1.04％ (4/386), respectively; TSH abnormal rates were 1.24％ (5/402), 1.51％ (6/397), 1.51％ (6/398) and 0.78％ (3/386), respectively, P < 0.05]. The rate of thyroid dysfunction in lactating women (7.95％, 31/390) was higher than those in the rest populations [1.24％ (5/402), 1.51％ (6/397), 1.51％ (6/398), 0.78％ (3/386), P < 0.05]. Conclusions The iodine intake of different populations in the survey area is generally sufficient, and the current salt iodine content standard can meet the iodine nutrition needs of different populations. Lactating women have a high rate of thyroid dysfunction. It is suggested to stick to the strategy of universal salt iodization to prevent iodine deficiency hazards in iodine deficiency areas, and further strengthen the monitoring of iodine nutrition and thyroid function of pregnant women and lactating women.

Objective? To explore the effect of rehabilitation nursing based on 5E concept in patients after SuperPath minimally invasive total hip replacemen(t THR). Methods? From February 2016 to February 2018, 194 patients who underwent THR through SuperPath approach in Huzhou Central Hospital of Zhejiang Province were selected as the study subjects. The patients were randomly divided into observation group (n=97) and control group by coin flipping method. The control group was given routine nursing care while the observation group was given the rehabilitation nursing based on 5E concept on the basis of that in the control group. The degree of pain, hip function score, incidence of complications and compliance of functional exercise were compared between the two groups. Results? The Harris score of the patients in the observation group was (65.25±5.29) at 1 month, (87.69±6.47) at 3 months and (93.85±8.66) at 6 months after operation, while that of the control group was (55.84±4.14), (77.48±5.89), (82.45±7.69). There were significant differences between the two groups (t=13.767, 11.511, 9.465;P＜ 0.05). The incidence of postoperative complications was 4.12% (4/97) in the observation group and 27.84% (27/97) in the control group (χ2=20.310, P＜ 0.05). The total compliance rate of functional exercise was 95.88% (93/97) in the observation group and 87.63% (85/97) in the control group, the difference was statistically significant (χ2=4.359,P＜ 0.05). The nursing satisfaction of patients in the observation group was 96.91% (94/97) and 81.44% (79/97) in the control group. The difference was statistically significant (χ2=12.015,P＜0.05). Conclusions? The application of comprehensive rehabilitation nursing based on 5E concept in SuperPath minimally invasive THR can effectively promote the recovery of hip function, reduce the occurrence of complications after operation, enhance the compliance of patients with functional exercise, and significantly improve the satisfaction of patients with nursing.
