Objective To observe the change of serum thyroid peroxidase antibody(TPOAb) in the patients with Hyperthyroidism and Thyroid gland tumor of different phases.Methods The level of TPOAb was observed,the relation between the changed TPOAb level and reduced thyroid function was studied.Results Among 89 cases,50 cases had normal or slightly elevated TPOAb level.However,after treatment,31 cases showed a raised TPOAb level.Of 19 cases with hypothyroidism or its sub-clinical type.There were 39 cases with positive TPOAb.After the treatment,2 cases changed to negative TPOAb,26 cases lowered,and 3 cases had hypothyroidism.There were 29 cases taking thyroid tablets without hypothyroidism.Conclusion The change of TPOAb level can be observed during the treatment for hyperthyroidism and t hyroid gland tumor.The elevated TPOAb level often predicts the decreased thyroid function.The patients with positive TPOAb should be carefully followed,and for hyperthyroidism patients the treatment should be taken with care.

Three hundred cases of E type viral hepatitis were observed with 100 cases of A type as control. We held that the etiology and pathogenesisof E and A types of viral hepatitis were wind, dampness, heat, poisons and stasis, each with its predominance; For A type, its predominant etiology being wind, heat and stasis, while that of E type, dampness, poisons and stasis. For their therapy, the principle of "similar treatment for different diseases " should, adopted. After treatment, ACT, TB, and a markedly decreased, signs and symptoms markedly improved, Epr, IgG also improved to different extents, the cured rate ( rate of negative virus exam) being 80% and 78% for A type and E type respectively. The effect was especially good for simple infection, and rather poor for mixed infection type.

AIM:To establish a rapid in vitro method for mast cell degranulation tracing by raster image corre-lation spectroscopy (RICS).METHODS:RBL-2H3, a basophilic granulocyte mast cell line transfected with CD 63-GFP plasmid, was used for evaluating the methods , including β-hexosaminidase ( HEX) colorimetric assay, scanning electron microscopy (SEM) and RICS in the detection of mast cell degranulation .The sensibilities of these methods were com-pared.RESULTS:The sensitivities of β-HEX colorimetric assay and SEM were 5 mg/L and 3.9 ×10 -2 mg/L, respec-tively.RICS detection showed obvious decrease in the diffusion coefficient at dose of 3.9 ×10 -2 mg/L.CONCLUSION:Fluorescent molecular diffusion dynamic measurement can be used for rapid tracing of allergic substances in vitro.Accord-ing to the results, RICS can achieve nearly the same extent of sensitivity as the SEM does and is far more sensitive than β-HEX colorimetric assay.Compared with SEM, RICS has several advantages: it is faster, simpler and cheaper; it can be used in living cells;it is more suitable for rapid in vitro allergenic compounds tracing .Therefore, RICS is applicable in clinic allergic antigen screening and may also be used in pharmaceutical quality control .

Objective:To evaluate the efficacy and safety of rituximab in pediatric myasthenia gravis (MG).Methods:Case series study. The clinical manifestations, laboratory tests, treatment plans and prognosis of 27 pediatric MG patients treated with rituximab from June 2013 to June 2023 at Children′s Medical Center of Peking University First Hospital were retrospectively collected.Results:There were 5 males and 22 females in 27 MG children. The onset age was 2.1 (1.6, 4.8) years, ranging from 8 months to 11 years. The clinical classification included 20 children (74%) of ocular MG and 7 children (26%) of generalized MG. Seventeen children (63%) had positive MG-related pathogenic antibodies, including 17 children of anti-AchR antibody and 1 of them also had anti-MuSK antibody. Rituximab was used as first-line immunosuppressant in 13 children, second-line immunosuppressant in 13 children and third-line immunosuppressant in 1 child. Immunosuppressants used before rituximab including 8 children of cyclosporine, 3 children of tacrolimus, 1 child of azathioprine, 1 child of mycophenolate mofetil and 1 child of cyclosporine combined with azathioprine. Rituximab was used for at least half a year with a follow-up period of more than 12 months. At the last follow-up after rituximab treatment, all children achieved improved or above, 14 children (52%) achieved complete stable remission, 7 children (26%) achieved pharmacologic remission, 1 child (4%) achieved minimal manifestations, and 5 children (18%) improved. After rituximab treatment, 27 children all could reduce the immunomodulation therapy and shorten the course of glucocorticoid therapy, and 22 children (81%) had stopped the glucocorticoid therapy. Among the 14 children with poor efficacy of other immunosuppressants, rituximab had complete stable remission of 7 children. The most common adverse reaction was respiratory infection (4 children (15%)). Only 2 children had allergic reaction to rituximab and got better after symptomatic treatment.Conclusions:Rituximab has good efficacy and tolerance in pediatric MG. Early application of rituximab can improve the prognosis and shorten the course of glucocorticoid treatment.

Objective: To evaluate the effects of extended nursing mode on the asthmatic children with allergic rhinitis (AR). Methods: Totally116 children aged 6-14 years old with asthma and AR were enrolled to this study from November 2015 to October 2016 in our hospital. They were divided into the regular nursing group and the extended nursing group according to the voluntary principle. The patients in regular nursing group were received routine nursing care in or out of hospital, while the patients in extended nursing group received extended care besides routine nursing. The children were required to record diary about asthma and AR And participate in asthma action projects. Before and after intervention we observed the quantitative score of symptoms and signs, the times of acute attack, the times of oblivion medication, the average days of stay in hospital, the days of fail to School or kindergarten, the lung function and the fractional exhaled nitric oxide (FeNO) in children with asthma and AR within 1 year. These above marks were assessed five times respectively at starting (baseline) , 3 months, 6 months, 9 months and 12 months (1 year) The differences between two groups were compared with appropriate statistical methods. Results: 1 year later, out of 58 cases in extended nursing group, 40 patients (68.97%)were in good control and 18 cases (31.03%) in partial control. Out of 58 cases in regular nursing group, 22 cases (37.93%) were in good control and 36 patients (62.07%) in partial control. There were significant differences between two groups in the effect of disease (χ²=11.23, all P<0.01), the experimental group was significantly better than the control group. The symptoms and signs of allergic rhinitis average scores in regular nursing group were 1.88 ± 0.72, extended nursing group were 0.79 ± 0.71, the difference was statistically significant (t=8.080, P<0.01) with the extended nursing group much better that the regular nursing group. The symptoms and signs of asthma average scores in regular nursing group were1.83 ± 0.75, extended nursing group were 0.88 ± 0.67, the difference was also statistically significant (t=7.133, P<0.01) with the extended nursing group much better that the regular nursing group. In extended nursing groups within 1 year the numbers of acute attack (0.60±0.59), the times of oblivion medication (11.05±7.40), the average days of stay in hospital (8.83±2.79) days,the average days of failing to school or kindergarten (8.69±5.46) days, while in regular nursing group within 1 year the numbers of acute attack(2.94±1.52), the times of oblivion medication (35.28±8.84), the average days of stay in hospital(20.95±5.46 days), the average days of fail to school or kindergarten(24.72±5.92) days, the differences were also statistically significant (t=10.50-15.87, P<0.01). The lung function in extended nursing group (PEF: 82.02±6.04, FEVI: 88.19±5.10, FEV25: 80.67±4.88, FEV50: 80.07±3.73, FEV75: 81.52±3.85) and in regular nursing group (PEF: 79.02±6.12,, FEV1: 80.52±4.72, FEV25: 75.05±7.79, FEV50: 77.59±4.60, FEV75: 78.41±4.19) . The differences were also statistically significant (t=2.90-6.15, P<0.01).The FeNO(13.66±2.87) ppb in extended nursing group and (14.95±3.12) ppb in regular nursing group. There were statistical significant differences between the two groups (t=2.30, P<0.05) with extended nursing group much better than regular nursing group. Conclusion The effect of extended care group is better than that of regular nursing group, and extended care is much more benefit to control asthma and allergic rhinitis in children.

ObjectiveTo analyze the epidemiological features and influencing factors of rabies in Shanxi Province，and to provide evidence to further promote the elimination of rabies in Shanxi Province. MethodsThe incidence data of rabies in Shanxi from 2011 to 2022 were collected and subjected to descriptive analysis. ResultsFrom 2011 to 2022， a total of 348 rabies cases were reported in Shanxi Province， with an average annual incidence of 0.080 3/10⁵. The incidence of rabies showed a downward trend overall. The highest incidence was in August. The cases were mainly farmers， mostly males， and most cases were reported between 50 and 69 years old. The data of cases showed that dogs were the main animals attacking human （93.96%）. The incubation period of most cases was 1‒3 months （37.37%）.The main exposure site was hand（51.33%）. Only 2.66% cases with grade Ⅲ exposure were injected with passive immune agents. ConclusionThe incidence of rabies in Shanxi Province continues to decrease， but there are still loopholes in prevention and control measures. It is necessary to strengthen the management and immunization of dogs，health education， and standardized procedures after exposure to maintain the achievements in the prevention and control of rabies.

ObjectiveTo observe the clinical efficacy and safety of Modified Guomin Decoction （加味过敏煎， MGD） in patients with mild to moderate atopic dermatitis （AD） of the traditional Chinese medicine （TCM） pattern of heart fire and spleen deficiency， and to explore its possible mechanisms. MethodsIn this randomized， double-blind， placebo-controlled study， 72 patients with mild to moderate AD and the TCM pattern of heart fire and spleen deficiency were randomly divided into a treatment group and a control group， with 36 cases in each group. The treatment group received oral MGD granules combined with topical vitamin E emulsion， while the control group received oral placebo granules combined with topical vitamin E treatment. Both groups were treated twice daily for 4 weeks. Clinical efficacy， TCM syndrome scores， Visual Analogue Scale （VAS） for pruritus， Dermatology Life Quality Index （DLQI） scores， Scoring Atopic Dermatitis （SCORAD） and serum biomarkers， including interleukin-33 （IL-33）， interleukin-1β （IL-1β）， immunoglobulin E （IgE）， and tumor necrosis factor-α （TNF-α） were compared before and after treatment. Safety indexes was also assessed. ResultsThe total clinical effective rates were 77.78% （28/36） in the treatment group and 38.89% （14/36） in the control group， with cure rates of 19.44% （7/36） and 2.78% （1/36）， respectively. The treatment group showed significantly better clinical outcomes compared to the control group （P＜0.05）. The treatment group exhibited significant reductions in total TCM syndrome scores， including erythema， edema， papules， scaling， lichenification， pruritus， irritability， insomnia， abdominal distension， and fatigue scores， as well as reductions in VAS， DLQI， SCORAD， and serum IgE and IL-33 levels （P＜0.05 or P＜0.01）. Compared to the control group， the treatment group had significantly better improvements in all indicators except for insomnia （P＜0.05）. No adverse events occurred in either group. ConclusionMGD is effective and safe in treating mild to moderate AD patients with heart fire and spleen deficiency pattern. It significantly alleviates pruritus， improves TCM syndromes and quality of life， and enhances clinical efficacy， possibly through modulation of immune responses.

Isolation rearing (IR) enhances aggressive behavior, and the central serotonin (5-hydroxytryptamine, 5-HT) system has been linked to IR-induced aggression. However, whether the alteration of central serotonin is the cause or consequence of enhanced aggression is still unknown. In the present study, using mice deficient in central serotonin Tph2 and Lmx1b, we examined the association between central serotonin and aggression with or without social isolation. We demonstrated that central serotonergic neurons are critical for the enhanced aggression after IR. 5-HT depletion in wild-type mice increased aggression. On the other hand, application of 5-HT in Lmx1b mice inhibited the enhancement of aggression under social isolation conditions. Dopamine was downregulated in Lmx1b mice. Similar to 5-HT, L-DOPA decreased aggression in Lmx1b mice. Our results link the serotoninergic system directly to aggression and this may have clinical implications for aggression-related human conditions.
