【Objective】 To analyze the contributing factors of attention deficit hyperactivity disorder (ADHD) in children and the correlation between bone mineral density and physical growth, in order to provide new clues for the prevention and early intervention of ADHD. 【Methods】 A total of 116 children with ADHD were included into the observation group from June 2020 to June 2022, while another 80 healthy children in the same period were included as the control group.Clinical data of the two groups were compared, and the factors influencing ADHD in children were analyzed using multivariate Logistic regression. Children with ADHD were further divided into boys group and girls group based on gender. Bone mineral density (BMD) and physical growth (height and body weight) of the two groups were measured, and the correlation between the two was analyzed. 【Results】 In the observation group, the proportion of boys, maternal bad behaviors during pregnancy, their educational level below high school, critical parenting, and parental stress index were significantly higher compared to the control group (χ2=14.430, 5.689, 5.630, 6.738, t=6.936, P<0.05). Additionally, family environment score was significantly lower than that in the control group (t=6.328, P<0.05). Logistic regression analysis revealed that factors including boys (OR=3.298, 95%CI: 1.759 - 6.184), maternal bad behaviors during pregnancy (OR=2.730, 95%CI: 1.169 - 6.375), maternal education level of senior high school or below (OR=2.032, 95%CI: 1.127 - 3.663), critical parenting (OR=2.349, 95%CI: 1.223 - 4.513), and parental stress index (OR=1.089, 95%CI: 1.055 - 1.124) were positively correlated with ADHD in children (P<0.05), while family environment score was negatively related to ADHD (OR=0.868, 95%CI: 0.820 - 0.919, P<0.05). There were no significant differences in BMD, height and body weight between boys and girls in ADHD group (P>0.05). Pearson correlation analysis indicated a positive correlation of BMD with height and body weight (r=0.409, 0.317, P<0.05). 【Conclusions】 The development of ADHD in children is associated with gender, maternal bad behavior during pregnancy, family parental style and so on. Bone mineral density is closely related to physical growth in children with ADHD, clinical interventions can be implemented to prevent or early intervene ADHD.

Objective:To observe the occurrence of attention deficit hyperactivity disorder(ADHD) in children aged 3-12 and analyze the related factors of family environment leading to ADHD.Methods:A total of 580 children from June 2020 to December 2021 were selected from the pediatric outpatient clinic of the Children's Hospital of Kunming.According to the diagnostic criteria for children with ADHD in DSM-5, all the subjects were divided into ADHD group ( n=37) and non-ADHD group( n=543). The general data questionnaire and family assessment device (FAD) were used to investigate the relevant data of children.SPSS 25.0 software was used for statistical analysis, and t test, Mann-Whitney U test were used for inter group comparison, and binary Logistic regression model was used to analyze the related factors of family environment of ADHD in children aged 3-12 years. Results:Among 580 children aged 3-12 in pediatric clinic, 37 cases were diagnosed ADHD, accounting for 6.38%.Compared with the non-ADHD group, the breast-feeding time of children in the ADHD group was shorter, the education level of primary caregivers was lower(5.00(2.50, 6.00)months, 9.00(7.00, 11.00)months)( U=7.751), the proportions of families with single parent/reconstituted and parents with criticism and reprimand as the main educational method were higher, and the FAD score((172.35±4.27), (116.29±5.58), t=6.478) was higher (all P<0.05). The results of Logistic regression analysis showed that longer breast-feeding time ( β=-0.561, P<0.001, OR=0.571, 95% CI=0.480~0.678) was the protective factor of ADHD in children aged 3-12 years.Primary and junior high schools as the education level of main caregivers, criticism and reprimand as the main education methods of parents, and poor family function (high FA score) were the related risk factors of family environment of ADHD in children aged 3-12 years. Conclusion:Family environment factors, such as short breast-feeding time, low education level of main caregivers, criticism and reprimand of parents, poor family function, can increase the incidence risk of ADHD in children aged 3-12 years.

Objective:To explore the benefits of speech training for young persons with tongue cancer after 125Ⅰ radioactive seed implantation. Methods:Fifty young persons bearing a 125Ⅰ radioactive seed implanted to treat tongue cancer were given up to 40min of daily tongue function training beginning on the second day after the operation. Abnormal sounds were corrected in the seven days before their discharge. An online platform assisted further training in the family combined with biofeedback. Daily 20-30 minute sessions were prescribed. Time domain waveforms, speech spectra and energy waterfalls were recorded from the 50 subjects before the experiment and after 1 week of the speech training. Intelligibility (PI) was quantified before the operation and the speech training, and then 1, 2, 4 and 6 months after discharge. Results:After 1 week of speech training abnormal waveforms had disappeared from the time domain waveform diagram. Fricative disturbance areas in the speech spectrum diagram had improved significantly, and the energy distribution in the energy waterfall diagram was balanced, showing a trend typical of normal speech fluctuation. The average PI before the operation (39.92±8.46) increased to (40.32±8.79) before the speech training and to (42.78±8.24) one month after discharge. It then continued to improve to (72.32±5.55) 6 months after discharge.Conclusion:Speech training can significantly improve the speech intelligibility of patients with tongue cancer after 125Ⅰ radioactive seed implantation.

The abnormal activation of HER family kinase activity is closely related to the development of human malignancies. In this study, we used HER kinases as targets for the treatment of nasopharyngeal carcinoma (NPC) and explored the anti-tumor effects of the novel pan-HER inhibitor HM781-36B, alone or in combination with cisplatin. We found that HER family proteins were positively expressed in tumor tissues of some NPC patients, and the high levels of those proteins were significantly related to poor prognosis. HM781-36B inhibited NPC in vitro and in vivo. HM781-36B exerted synergistic effects with cisplatin on inhibiting proliferation and promoting apoptosis of NPC cells. In NPC xenograft models in nude mice, HM781-36B and cisplatin synergistically inhibited tumor growth. Downregulating the activity of HER family proteins and their downstream signaling pathways and regulating tumor microenvironment may explain the synergistic anti-tumor effects of HM781-36B and cisplatin. In conclusion, our study provides evidence for HER family proteins as prognostic biomarkers and potential therapeutic targets for NPC. The pan-HER inhibitor HM781-36B alone or in combination with cisplatin represents promising therapeutic effects for the treatment of NPC patients, which provides a new idea for the comprehensive treatment of NPC.

Objective:To investigate the short-term effects of articular injection of hyaluronic acid combined with glucocorticoid in patients with knee osteoarthritis.Methods:From October 2017 to June 2018, a total of 188 patients diagnosed with knee osteoarthritis received parallel articular injection. There were 60 cases with mild knee osteoarthritis, 72 with moderate and 56 with severe according to the WOMAC knee functional score. There patients were divided into group rank Ⅰ48 cases, Ⅱ 49 cases, Ⅲ 45 cases, Ⅳ 46 cases according to the knee joint X-ray Kellgren-Lawrence classification. The unified treatment regimen was 2.5 ml Sodium Hyaluronate (SHA) injection for the first time, SHA 2.5 ml and compound betamethasone injection (CBI) 1 ml for the second week, and 2.5 ml of SHA for the third week. WOMAC score and Lequesne index were used to evaluate joint function before the first injection and after SHA and SHA+CBI injection. The improvement rate of Lequesne index ≥30% or improvement rate of WOMAC score ≥25% was regarded as effective treatment.Results:Lequesne index and WOMAC score decreased gradually in the mild, moderate and severe groups after 3 weeks of injection. Among these patients, the improvement rates of Lequesne index after SHA injection and SHA+CBI injection were 36.44%±8.46% and 49.26%±13.75% in the mild group, 23.09%±12.61% and 30.66%±14.95% in the moderate group, and 10.50%±8.78% and 11.07%±6.52% in the severe group. The improvement rate of WOMAC score in the mild group after SHA injection and after SHA+CBI injection was greater than 25%. After SHA injection, the improvement rate of WOMAC score was 13.06%±10.21% in the moderate group, and 27.49%±13.61% after SHA+CBI injection. Those in severe group were all less than 25%. Kendall's staub correlation analysis results showed that there was a strong positive correlation between WOMAC function score and X-ray Kellgren-Lawrence classification ( r=0.744, P<0.001). The Lequesne index and WOMAC scores of the Kellgren-Lawrence X-ray classification decreased gradually after 3 weeks of injection. The improvement rate of Lequesne index period in group rank Ⅰ after SHA and SHA+CBI injection was 36.64%±10.05% and 52.00%±8.19%, respectively. That for group rank Ⅱ was 32.05%±8.09% and 41.95%±10.53%, group rank Ⅲ 16.93%±10.34% and 27.77%±10.25%, group rank Ⅳ 7.52%±5.53% and 7.60%±6.66%. The improvement rate of WOMAC score period in group rank Ⅰ after SHA and SHA+CBI injection was 29.48%±11.77% and 42.59%±13.55%, respectively. That for group rank Ⅱ was 26.72%±10.21% and 30.49%±16.90%, group rank Ⅲ 13.78%±5.96% and 23.05%±9.52%, group rank Ⅳ 4.77%±3.80% and 4.27%±4.23%. Conclusion:For mild or X-ray classification Ⅰ, Ⅱ knee osteoarthritis patients, articular injection SHA or SHA+CBI are effective. Further, SHA+CBI is better than single injection of SHA. SHA+CBI injection was effective for moderate knee osteoarthritis patients. For severe or X-ray classification Ⅲ, Ⅳ patients, SHA or SHA+CBI injection at interval are invalid.

OBJECTIVE:To study the effect of natural emulsifier acacia senegal on in vivo and in vitro performance of chloro-genic acid self-microemulsion. METHODS:Chlorogenic acid self-microemulsion containing acacia senegal(new chlorogenic acid self-microemulsion)was prepared by using acacia senegal to gradually replace polysorbate 80 in chlorogenic acid self-microemul-sion containing nonionic emulsifier (traditional chlorogenic acid self-microemulsion). The appearance,morphology,particle size,conductivity,pH value,stability,in vitro release and intestinal absorption kinetics of the 2 kinds self-microemulsions were evaluated. RESULTS:50％of polysorbate 80 was replaced by acacia senegal in new chlorogenic acid self-microemulsion. The tradi-tional and new chlorogenic acid self-microemulsions had clear appearance,and approximately spherical drops. Particle sizes were (24.53 ± 3.03),(35.51 ± 5.91) nm;dectrical conductivities were (195.6 ± 0.3),(189.5 ± 0.4)μs/cm;and pH were 3.87 ± 0.02, 4.08 ± 0.03 (n=3),respectively. Compared with traditional chlorogenic acid self-microemulsion,the absorption rate constant,ef-fective permeability coefficient and absorption amount of the new one in duodenum,jejunum,ileum were increased a little (P>0.05);the above indexes in colon were obviously decreased (P<0.05). CONCLUSIONS:The new chlorogenic acid self-micro-emulsion can maintain the performance of traditional one,and increase absorption of chlorogenic acid in small intestine.

<p><b>OBJECTIVE</b>To determine whether the extent of prolongation of the transisthmus interval after ablation predicts complete bidirectional block.</p><p><b>METHODS</b>Since 1996 to 2002, 30 consecutive patients underwent ablation procedures for isthmus-dependent atrial flutter. There were 23 males and 7 females [mean age (47.85 +/- 9.35) years]. With the use of fluoroscopic view of anatomy, radiofrequency ablation was performed during coronary sinus pacing at a cycle length of 600 ms.</p><p><b>RESULTS</b>Bidirectional block was achieved with ablation in 29 (97%) of 30 patients. The transisthmus intervals before ablation and after complete transisthmus block were (73.82 +/- 13.01) ms and (140.47 +/- 20.48) ms, respectively, in the clockwise direction (P < 0.0001), and (77.63 +/- 8.36) ms and (138.17 +/- 15.55) ms, respectively, in the counterclockwise direction (P < 0.0001). A period of incomplete isthmus block was observed during 17 (58%) of the 29 ablation procedures. The clockwise transisthmus intervals during incomplete block [(107.65 +/- 21.33) ms] were (45.5 +/- 8.7)% longer than the baseline transisthmus intervals. An increase in the transisthmus interval by > or = 50% in both directions after ablation predicted complete bidirectional block with 100.0% sensitivity and 83.3% specificity. The positive and negative predictive values were 90.6% and 100.0%, respectively. The diagnostic accuracy of a > or = 50% prolongation in the transisthmus interval was 83.3%.</p><p><b>CONCLUSION</b>The analysis of transisthmus interval is a valuable method for determining complete bidirectional isthmus block.</p>
