Objective To explore the medication rules and mechanism of action of traditional Chinese medicine compound patent formulas for vitiligo,and provide ideas for the development and the patent declaration work of new Chinese medicines for vitiligo.Methods China Patent Publication Bulletin website,National Knowledge Infrastructure Database,Patent Information Service Platform of China Intellectual Property Right Net(CNIPR),and Baiten Patent Platform were used to search for the patents of traditional Chinese medicine compound formulas for vitiligo from the establishment of the databases to 30th September,2023.Excel software and Traditional Chinese Medicine Inheritance Computing Platform(TCMICS V3.0)were used to establish a database of compound formulas,and carry out the statistics of frequency,association rules and clustering analysis of the formulas for internal and external prescriptions.The target and mechanism of action of the internal prescriptions of core high-frequency Traditional Chinese Medicine group for the treatment of vitiligo were further explored by Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),Symptom Mapping(Symmap),The Human Gene Database(Genecards),UniversalProtein(UniProt),STRING,Pharmaceutical DataBase(PDB)and other databases as well as software such as R Studio 4.2.2 and Cytoscape 3.9.1,and AutoDock Vina was used for molecular docking validation.Results The internal formulas included 335 patents and the external formulas included 189 patents.The rules of internal and external use are similar.The high-frequency traditional Chinese medicines are Tribuli Fructus,Psoraleae Fructus,Angelicae sinensis,Radix Polygoni Multiflori,Carthami Flos,Angelica dahurica,etc.;the key efficacies of the medicines are based on tonifying the deficiency,activating blood circulation and removing blood stasis;and the properties of the Chinese medicines are the nature of warmth,coldness and flatness,sweetness,bitterness,pungency and attribution to the liver,the spleen,the heart and the kidneys.Commonly used oral medicine pairs are Chuanxiong rhizome-Angelica,Astragalus-Angelica,etc.,high-frequency pairs of external medicines are Fructus mume-Psoraleae fructus,cuscuta-Psoraleae fructus,etc.;internal and external clustering of the core drugs are Psoraleae fructus,Tribuli Fructus,Angelica,Polygonum multiflorum,Angelica dahurica,Safflower,and other high-frequency medicines.The key targets of internal patents for the treatment of vitiligo are genes such as albumin,protein kinase B1,cystatinase 3,etc.The main active ingredients of the internal grouping for the treatment of vitiligo may be quercetin,kaempferol,luteolin,etc.,and the therapeutic mechanism may be related to the end products of glycosylation/receptor for glycosylation end products,tumour necrosis factor signalling pathway,phosphatidylinositol 3-kinase/protein kinase B and other signalling pathways,and involved in the process of blood lipids and atherosclerosis,human cytomegalovirus infection.The molecular docking results confirmed the docking activity of the herbal components with key receptor proteins.Conclusion This study reveals the similarity between the internal and external patented formulas of vitiligo in terms of medication,flavour,and meridian,suggesting that the pathways and indexes such as albumin,interleukin,and tumour necrosis factor of vitiligo patients can be improved by tonifying the liver and kidney,activating blood circulation and removing blood stasis,which also provides a reference for the research and development of new medicines for vitiligo,patent protection,and the use of clinical prescriptions.

ObjectiveTo investigate the therapeutic effect and mechanism of coptisine on chronic atrophic gastritis （CAG） in rats based on the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. MethodA CAG rat model was induced by multiple factors， including sodium salicylate， N-methyl-N′-nitro-N-nitrosoguanidine （MNNG）， and irregular feeding. The successfully modeled rats were randomly divided into the model group， folic acid group， and high- and low-dose coptisine groups. The high- and low-dose coptisine groups were given coptisine （50， 10 mg·kg^-1， respectively）， and the folic acid group was given folic acid at 2 mg·kg^-1 for 60 days. The pathological changes were detected by hematoxylin-eosin （HE） staining. The ultrastructure of gastric mucosal cells was observed by electron microscopy. Serum pepsinogen Ⅰ （PGⅠ）， pepsinogen Ⅱ （PGⅡ）， and PGⅠ/PGⅡ ratio （PGR） were detected by immunoturbidimetry. Serum gastrin-17 （G-17） level was detected by radioimmunoassay. The content of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α） and interleukin-1β （IL-1β） in serum of rats was detected by enzyme-linked immunosorbent assay （ELSIA）. Western blot analysis was used to detect the expression levels of TGF-β₁， PI3K， phosphorylated-Akt （p-Akt）， mTOR， and phosphatase and tensin homolog deleted on chromosome 10 （PTEN） in gastric mucosa. The mRNA levels of TGF-β₁， PI3K， Akt， mTOR， PTEN， microtubule-associated protein light chain 3Ⅱ （LC3Ⅱ）， and Beclin-1 were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the normal group， the model group showed atrophy and reduced number of intrinsic glands in the gastric mucosal tissues， as well as inflammatory cell infiltration. The ultrastructure of gastric mucosal cells in the model group displayed nuclear condensation， reduced and swollen mitochondria， and abnormal structure. The serum levels of G-17， PGⅠ， PGR， and the protein and mRNA levels of PTEN in gastric tissues were significantly lower in the model group （P<0.01）， while serum levels of IL-6， IL-1β， TNF-α， and the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR in gastric tissues were significantly higher （P<0.01）. Compared with the model group， various drug intervention groups showed different degrees of improvement in pathological damage and gastric mucosal cell ultrastructure， significantly increased serum levels of G-17， PGⅠ， and PGR （P<0.05，P<0.01）， and significantly decreased levels of IL-6， IL-1β， and TNF-α （P<0.05，P<0.01）. The high-dose coptisine group significantly downregulated the protein and mRNA levels of TGF-β₁， PI3K， Akt， and mTOR （P<0.05，P<0.01）. ConclusionBerberine has a therapeutic effect on CAG in rats， possibly exerting a protective effect on gastric mucosa by inhibiting inflammation and blocking the PI3K/Akt/mTOR signaling pathway.

ObjectiveTo explore the relationships between internet gaming disorder (IGD), interpersonal needs, loneliness, and depression in adolescents through the construction of a chain mediation model, to clarify the underlying mechanisms of these associations, and to provid a theoretical basis for depression prevention and intervention. MethodsBased on the data of the 7th Population Census, using convenient sampling method 1 106 adolescents aged between 10‒19 years in South China (176), North China (147), Central China (332), and East China (451) were selected to conduct a cross-sectional survey, with a ratio of 1∶1∶1.5∶2.5. The survey was conducted with a questionnaire consisting of general information (sex, age, grade, parents’ education level), the Chinese version of the IGDS9-SF, the INQ-15, the short-form of the ULS-8 and the PHQ-9 were used to evaluate the depression status of adolescents. Spearman correlation analysis was used to explore the correlation between the variables. A multiple-mediator model was constructed using IBM SPSS Statistics 22.0 PROCESS to examine the mediating effects of interpersonal needs and loneliness on the relationship between IGD and depression. The significance of the chain mediating effect was tested using the Bootstrap method. ResultsOverall, 39.06% (432/1 106) adolescents experienced depression. The incidence of depression among adolescents with smoking and without smoking was 62.50% and 38.36%, respectively. Similarly, the incidence of depression among adolescents with alcohol consuming and without alcohol consuming was 61.94% and 35.94%, respectively. There were statistically significant differences between IGD, interpersonal needs, loneliness, and depression (P<0.01). The chain mediation model demonstrated a good fit, and the bootstrap test showed that the 95%CI of each mediation path did not include 0, indicating significant mediation effects. The overall effect was 0.337. The direct effect of IGD on depression was significant (effect value=0.138, 95%CI:0.102-0.173, P<0.001). The mediation effects included three paths: ① IGD →interpersonal needs → depression (effect value=0.073, P<0.05), accounting for 21.47% of the total effect;② IGD→ loneliness → depression (effect value=0.093, P<0.05), accounting for 27.35%; and ③ IGD → interpersonal needs → loneliness → depression (effect value=0.036, P<0.05), accounting for 10.59%. ConclusionInterpersonal needs and loneliness independently and jointly mediate the relationship between IGD and depression among adolescents. To reduce depression and improve mental health in this population, measures should be taken to prevent and intervene in IGD, address adolescents’ social and emotional needs, enhance satisfaction of interpersonal needs, and reduce loneliness.

AIM: To evaluate the binocular visual function in high myopia patients after the implantation of implantable collamer lens(ICL)V4c.METHODS: A total of 35 cases(70 eyes)that received binocular ICL implantation at our hospital from May 2019 to May 2021 were enrolled in this prospective study. Binocular full-range visual acuity, contrast sensitivity, stereopsis, mesopic vision and glare sensitivity, and monocular wavefront and the quality of vision questionnaire were assessed before the surgery and at 1 mo postoperatively.RESULTS: At 1 mo postoperatively, 35 cases(100%)had binocular uncorrected distance visual acuity(UDVA)≤0.00(LogMAR), 16 cases(46%)had binocular UDVA≥preoperative corrected distance visual acuity(CDVA). Binocular UDVA and uncorrected intermediate visual acuity(UIVA,80 cm)were improved compared to preoperative CDVA and distance-corrected intermediate visual acuity(DCIVA,80 cm)(all P<0.05).While there were no differences in the binocular postoperative UIVA(60 cm)and preoperative DCIVA(60 cm),and uncorrected near visual acuity(UNVA,40 cm)and preoperative distance-corrected near visual acuity(DCNVA,40 cm)(all P>0.05). The binocular contrast sensitivity was significantly improved postoperatively(P=0.001), and the postoperative binocular mesopic vision, glare sensitivity(no glare/glare)and binocular stereopsis(5 m/40 cm)had no differences(all P>0.05). The postoperative total higher-order aberration, trefoil aberration, coma and spherical aberration were increased, besides the median of total coma in the right eye with a pupil diameter of 3.0 mm was decreased after surgery. The mean total score of quality of vision questionnaire was significantly increased from 54.87 preoperatively to 80.92 after implantation(P<0.05), with high satisfaction and no obvious visual disturbance in patients.CONCLUSION: Although the monocular high-order aberrations increased in the early stage after ICL V4c binocular implantation in patients with high myopia, the binocular visual function was improved.

Objectives:To explore the influencing factors of inter-arm systolic blood pressure difference(sIAD)in young hypertensive population. Methods:A total of 12 895 young Kailuan employees aged≤40 years,who participated in the physical examination from 2010 to 2020,were enrolled in this study.All of them underwent blood pressure measurements of four limbs in supine position.Young hypertensive group(n=3 584)and young non-hypertensive group(n=3 584)were 1∶1 matched by sex and age(±1 year),and participants were further divided into sIAD＜10 mmHg(1 mmHg=0.133 kPa)and sIAD≥10 mmHg subgroups.A stepwise multivariate logistic regression model was established to analyze the determinants of sIAD≥10 mmHg. Results:The detection rate of sIAD≥10 mmHg was significantly higher in the young hypertensive group than in the young non-hypertensive group(31.72%vs.27.76%,P＜0.001).Stepwise multivariate logistic regression analysis showed that in young hypertensive population,ankle-brachial index(ABI)＜0.9,male,obesity,overweight,elevated low density lipoprotein cholesterol(LDL-C)level,and systolic blood pressure were positively associated with sIAD≥10 mmHg,while college education or above,physical exercise were negatively correlated with sIAD≥10 mmHg(all P＜0.05).In the young non-hypertensive population,ABI＜0.9,systolic blood pressure were positively correlated with sIAD≥10 mmHg,while age was negatively associated with sIAD≥10 mmHg(all P＜0.05). Conclusions:The detection rate of sIAD≥10 mmHg is higher in young hypertensive population than in young non-hypertensive population.Decreased ABI,male sex,obesity,overweight,increased LDL-C level,systolic blood pressure,college education and above,and physical exercise are the influencing factors of sIAD≥10 mmHg in young hypertensive population.

BACKGROUND: Significant brain volume deviation is an essential phenotype in children with neurodevelopmental delay (NDD), but its genetic basis has not been fully characterized. This study attempted to analyze the genetic factors associated with significant whole-brain deviation volume (WBDV). METHODS: We established a reference curve based on 4222 subjects ranging in age from the first postnatal day to 18 years. We recruited only NDD patients without acquired etiologies or positive genetic results. Cranial magnetic resonance imaging (MRI) and clinical exome sequencing (2742 genes) data were acquired. A genetic burden test was performed, and the results were compared between patients with and without significant WBDV. Literature review analyses and BrainSpan analysis based on the human brain developmental transcriptome were performed to detect the potential role of genetic risk factors in human brain development. RESULTS: We recruited a total of 253 NDD patients. Among them, 26 had significantly decreased WBDV (<-2 standard deviations [SDs]), and 14 had significantly increased WBDV (>+2 SDs). NDD patients with significant WBDV had higher rates of motor development delay (49.8% [106/213] vs . 75.0% [30/40], P  = 0.003) than patients without significant WBDV. Genetic burden analyses found 30 genes with an increased allele frequency of rare variants in patients with significant WBDV. Analyses of the literature further demonstrated that these genes were not randomly identified: burden genes were more related to the brain development than background genes ( P  = 1.656e -9 ). In seven human brain regions related to motor development, we observed burden genes had higher expression before 37-week gestational age than postnatal stages. Functional analyses found that burden genes were enriched in embryonic brain development, with positive regulation of synaptic growth at the neuromuscular junction, positive regulation of deoxyribonucleic acid templated transcription, and response to hormone, and these genes were shown to be expressed in neural progenitors. Based on single cell sequencing analyses, we found TUBB2B gene had elevated expression levels in neural progenitor cells, interneuron, and excitatory neuron and SOX15 had high expression in interneuron and excitatory neuron. CONCLUSION Idiopathic NDD patients with significant brain volume changes detected by MRI had an increased prevalence of motor development delay, which could be explained by the genetic differences characterized herein.

Abstract The study elaborates on the historical development of the home-school-community partnership in the United States, as well as physical activity strategies to prevent overweight and obesity in school age children. Feasible suggestions are proposed for implementing the home-school-community collaboration in China. The finding suggests that in addition to cooperation with schools, families and communities need to take initiatives to actively support children s participation in various physical activities and provide facilities and guarantees. Schools should also do a top level design that links with families and communities, and incorporate their participation into long term physical education planning, making them an integral part of a closely interconnected collaborative network to further prevent overweight and obesity in school age children.

Objective:To measure the anatomical parameters of three-dimensional available space of S 1 and S 2 vestibules on Chinese adults by imaging methods, and discuss their clinical values. Methods:Data of 200 cases of pelvic CT with complete posterior ring were collected from January 2015 to January 2021, included 110 males and 90 females. The ages ranged from 21 to 63 years (average, 40.72±10.70 years). Then the parameters of both the left vestibule and the right vestibule of S 1 and S 2 such as vestibular width, vestibular height and vestibular area were measured by the three-dimensional CT reconstructions. Statistical analyses were performed among the groups which were classified according to the gender, side of vestibule to compare the difference of vestibular morphological characteristics among different groups. Results:The average vestibular area of S 1 was 425.71± 45.07 mm 2 (range, 296.3-604.4 mm 2), which was 449.80±28.62 mm 2 (range, 338.3-604.4 mm 2) in males and 388.25±34.01 mm 2 (range, 296.3-498.4 mm 2) in females. The average vestibular width was 28.52±4.34 mm (range, 17.1-36.3 mm), 31.77±2.33 mm (range, 22.46-36.30 mm) in males and 24.55±2.55 mm (range, 17.1-26.1 mm) in females. The mean vestibular height was 21.05±2.29 mm (range, 17.5-32.0 mm), with 21.34±2.37 mm (range, 18.5-32.0 mm) of men and 20.69±1.60 mm (range, 17.5-25.6 mm) of women. The mean S 2 vestibular area was 230.19±35.57 mm 2 (range, 142.5-297.3 mm 2), which was 258.91±28.04 mm 2 (range, 218.3-297.3 mm 2) in males and 205.61±24.12 mm 2 (range, 142.5-258.6 mm 2) in females. The average vestibular width was 15.94±1.72 mm (range, 12.4-20.3 mm), 16.51±1.59 mm (range, 14.4-20.3 mm) in male and 15.25±1.63 mm (range, 12.4-18.1 mm) in female. The mean vestibular height was 14.30±1.20 mm (range, 12.9-17.8 mm), 15.49±1.46 mm (range, 13.6-17.8 mm) in males and 13.73±0.93 mm (range, 12.9-16.1 mm) in females. There were significant differences in vestibular width, height and area between S 1 and S 2 (vestibular width t=3.934, P< 0.001; vestibular height t=3.692, P< 0.001; vestibular area t=4.816, P< 0.001). There were significant differences in S 1 vestibular width, S 1 vestibular height, S 1 and S 2 vestibular area between male groups and female groups (S 1 vestibular width: t=2.969, P=0.003; S 1 vestibular height: t=0.316, P=0.049; S 1 vestibular area: t=1.975, P=0.049; S 2 vestibular area: t=2.023, P=0.044). While there was no significant difference in S 2 vestibular width and height between the two gender groups. There were significant differences in S 1 and S 2 vestibular width, height and area between male and female groups ( P < 0.001). There were no significant difference in parameters between the left and right values of the same vestibular site. Conclusion:The parameters of S 1 sacral vestibule are larger than that of S 2. It implies that S 1 was more feasible to insert iliosacral screws than S 2; lesser diameter iliosacral screws should be selected to insert into S 2. The female S 1 vestibule is smaller than the male, so the iliosacral screws placement has more stringent requirements on the selection of the insertion point and the direction of the screw. And the surgeon can utilize the intact contralateral sacral vestibule as the damaged side to proceed the iliosacral screw inserted simulation.

Objective:To understand the contents of edible salt iodine and urinary iodine of children and pregnant women in Yunnan Province, and to evaluate the iodine nutrition status, so as to provide a basis for scientific prevention and treatment of iodine deficiency disorders (IDD).Methods:From November to December 2020, one county (city) was selected from each prefecture (city), two townships (towns and streets) were selected from each county (city) and two villages (neighborhood committees) were selected from each township (town and street) from each of the 16 prefectures (cities) in Yunnan Province as the investigation sites. A total of 20 non-boarding children (male and female balanced) aged 8 - 10 years old were selected from each primary school in each village (neighborhood committee) to collect salt and urine samples. A total of 80 children were investigated in each county (city). A total of 20 pregnant women were selected from each township (town and street) to collect salt and urine samples. A total of 40 pregnant women were investigated in each county (city). All salt samples and urine samples were tested for iodine contents.Results:A total of 2 009 salt samples and 2 041 urine samples (1 375 for children, 666 for pregnant women) were collected from children aged 8 - 10 years old and pregnant women in 16 counties (cities) of Yunnan Province. Among them, the median salt iodine was 26.0 mg/kg, the coverage rate of iodized salt was 100.0% (2 009/2 009), the qualified rate of iodized salt was 98.7% (1 982/2 009), and the consumption rate of qualified iodized salt was 98.7% (1 982/2 009). The difference of salt iodine content in key populations in different counties (cities) was statistically significant ( H = 258.98, P < 0.01). The median urinary iodine of children aged 8 - 10 years old was 188.5 μg/L. There was statistically significant difference in urinary iodine content among children of different ages ( H = 29.45, P < 0.01), but there was no statistically significant difference in urinary iodine content among children of different genders ( H = 1.43, P > 0.05). In addition, the median urinary iodine of pregnant women was 141.9 μg/L, 52.1% (347/666) was < 150 μg/L. There was statistically significant difference in urinary iodine content of pregnant women in different counties (cities, H = 88.32, P < 0.01). Conclusions:The qualified rate of iodized salt, the coverage rate of iodized salt and the consumption rate of qualified iodized salt in key populations of Yunnan Province are more than 90%, and the iodized salt supply is good. Iodine nutrition of children aged 8 - 10 years old is at an appropriate level (100 - 199 μg/L); iodine nutrition of pregnant women is in an state of iodine deficiency ( < 150 μg/L). It is suggested to strengthen IDD monitoring and health education among key populations, improve residents' awareness of disease prevention, and make scientific iodine supplementation.

Objective: To investigate the policies and coverage of influenza vaccine during the influenza epidemic seasons of 2020-2021 and 2021-2022 in China. Methods: The national influenza vaccination policy and vaccination rate were investigated in counties and districts and described in the two epidemic seasons. Results: In the epidemic seasons of 2020-2021 and 2021-2022, the vaccination coverage of influenza in China was 3.16% and 2.47%, respectively. The free vaccination policy had the highest vaccination coverage (51.75% and 38.32%), followed by the medical insurance reimbursement policy (9.74% and 7.36%). During the epidemic season of 2021-2022, the number of counties and districts implementing the free vaccination policy in China decreased 61 compared with the previous year, but the number of people covered increased by 51.29%. However, the vaccination coverage of the vast population decreased significantly, with the medical staff (75.69% and 40.15% for two epidemic seasons), preschool children (58.86% and 26.15%), and the elderly (45.71% and 32.94%). During the epidemic season of 2021-2022, the number of counties and districts implementing the medical insurance reimbursement policy increased by 6 compared with the previous year, and the number of people covered increased by 11.12%, but the vaccination coverage decreased. Conclusion: The influenza vaccination rate in China is low, and the implementation of cost preferential policy can greatly improve the influenza vaccination rate.
