0. 05), respectively. Conclusion: Repeated +Gz stress may disorder the ratio of ET and NO. This imbalance may be one of the causes which lead to pathology changes in masseter musscles.

Objective To explore the efficacy and prognostic independent factors of modified island flap(OIF)and urethroplasty(tip)in the treatment of hypospadias in children.Methods The 164 children with hypospadias analyzed retrospectively were treated from February,2013 to February,2021.They were divided into two groups according to the operation method.82 patients in tip group were treated with tip and 82 patients in OIF group were treated with OIF.The treatment effects of the two groups were compared.Then they were divided into two groups according to the cure condition,namely,the good prognosis group(cured by operation,151 case)and the poor prognosis group(not cured by operation,13 case).Independent factors affecting the prognosis of children were analyzed by binary logistic regression.Results The cure rate of OIF group was 96.34％,which was higher than that of the tip group(87.8％),and the incidence of postoperative complications in OIF group was 7.32％,which was lower than that of the tip group(23.17％,P＜0.05).The operation time in tip group(95.95±12.35)min,which was shorter than that of the OIF group(P＜0.05).At the same time,the binary logistic regression analysis showed that the degree of hypospadias and the classification of barcat were the prognostic factors of children with hypospadias.The degree of penis bending,the width of penis head and the method of operation were suspicious factors.Conclusion OIF and tip have good effects in the treatment of hypospadias in children.OIF has a higher success rate,tip has a shorter operation time and fewer postoperative complications.However,the independent factors affecting the prognosis of children are preoperative hypospadias classification and barcat classification.This operation method is not an independent factor affecting the prognosis.

ObjectiveTo investigate the effect of Xinfeng capsules on immunoinflammatory indicators in patients with rheumatoid arthritis （RA） due to spleen deficiency and dampness exuberance. MethodA total of 102 patients were randomly divided into control group and observation group according to the random number table method， with 51 cases in each group. All patients were treated with methotrexate tablets， while those in the observation group received additional Xinfeng capsules. The course of treatment in both groups was 12 weeks. The 28-joint disease activity score （DAS28）， visual analogue scale （VAS） scores， morning stiffness time， erythrocyte sedimentation rate （ESR）， high-sensitivity C-reactive protein （hs-CRP）， rheumatoid factor （RF）， anti-cyclic citrullinated peptide （anti-CCP） antibody， vascular endothelial growth factor （VEGF）， and serum amyloid A （SAA） of the two groups before and after treatment were compared. The efficacy and incidence of adverse events were compared between the two groups. The Apriori association rule model and random walk model were constructed to evaluate the effect of Xinfeng capsules in improving hs-CRP， ESR， RF， SAA， VEGF， and anti-CCP. ResultThere were no dropouts in this study. There was no statistical difference in the indicators between the two groups before treatment. After 12 weeks of treatment， the total effective rate in the observation group was 90.19% （46/51）， which was higher than 74.51% （38/51） in the control group （χ²＝4.320，P<0.05）. DAS28， VAS score， and morning stiffness time in the observation group were improved compared with those in the control group （P<0.05）. Apriori association rule model results showed that the application of Xinfeng capsules in the observation group had a strong correlation with the reduction of RF， ESR， hs-CRP， SAA， and VEGF. The results of the random walk model showed that the improvement coefficients of hs-CRP， ESR， RF， SAA， and VEGF in the observation group were all better than those of the control group， and the improvement coefficient of anti-CCP in the control group was better than that of the observation group. The improvement degree of hs-CRP， ESR， RF， SAA， and VEGF in the observation group was superior to that of the control group （P<0.05）. The incidence of adverse reactions in the observation group was lower than in the control group （χ²＝4.057，P<0.05）. ConclusionOn the basis of the treatment with methotrexate tablets， Xinfeng capsules can effectively improve the immunoinflammatory level in RA due to spleen deficiency and dampness exuberance and reduce the incidence of adverse reactions.
