ObjectiveTo evaluate the efficacy and safety of Xiaoji Hufei Formula in protecting children with close contact exposure to influenza， and to provide reference and evidence-based support for better clinical prevention and treatment of influenza in children. MethodsA multicenter， prospective， non-randomized， parallel， controlled trial was conducted from October 2021 to May 2022 in five hospitals， including Dongfang Hospital of Beijing University of Chinese Medicine. Confirmed influenza cases and influenza-like illness （ILI） cases were collected， and eligible children with close contact exposure to these cases were recruited in the outpatient clinics. According to whether the enrolled close contacts were willing to take Xiaoji Hufei formula for influenza prevention， they were assigned to the observation group （108 cases） or the control group （108 cases）. Follow-up visits were conducted on days 7 and 14 after enrollment. The primary outcomes were the incidence of ILI and the rate of laboratory-confirmed influenza. Secondary outcomes included traditional Chinese medicine （TCM） symptom score scale for influenza， influenza-related emergency （outpatient） visit rate， influenza hospitalization rate， and time to onset after exposure to influenza cases. ResultsA total of 216 participants were enrolled， with 108 in the observation group and 108 in the control group. Primary outcomes： （1） Incidence of ILI： The incidence was 12.0% （13/108） in the observation group and 23.1% （25/108） in the control group， with the observation group showing a significantly lower incidence （χ²=4.6， P<0.05）. （2） Influenza confirmation rate： 3.7% （4/108） in the observation group and 4.6% （5/108） in the control group， with no statistically significant difference. Secondary outcomes： （1） TCM symptom score scale： after onset， nasal congestion and runny nose scores differed significantly between the two groups （P<0.05）， while other symptoms such as fever， sore throat， and cough showed no significant differences. （2） Influenza-related emergency （outpatient） visit rate： 84.6% （11 cases） in the observation group and 96.0% （24 cases） in the control group， with no significant difference. （3） Time to onset after exposure： The median onset time after exposure to index patients was 7 days in the observation group and 4 days in the control group， with a statistically significant difference （P<0.05）. ConclusionIn previously healthy children exposed to infectious influenza cases under unprotected conditions， Xiaoji Hufei formula prophylaxis significantly reduced the incidence of ILI. Xiaoji Hufei Formula can be recommended as a specific preventive prescription for influenza in children.

Objective To investigate the mechanism of Chonghe soft extract on ulcer wound healing in diabetic rats through protein kinase B(Akt)/mammalian Sirolimus target protein(mTOR)-mediated nucleotides binding oligomeric acid domain-like receptor protein 3(NLRP3)inflammasome inactivation.Methods Thirty six SD rats with diabetic ulcer,which were established by feeding with high glucose and high fat diet and injecting intraperitoneally with streptozocin(STZ)combined with skin defect,were randomly divided into model group,Chonghe soft extract group and growth factor group,with twelve rats in each group.Another twelve SD rats were injected an equal dose of citric acid-sodium citrate buffer solution and used as blank group.The blank group and the model group were not received drug intervention,but the Chonghe soft extract group and the growth factor group were externally applied Chonghe soft extract and growth factor gel,respectively.The wound healing of each group was observed and recorded.After 7 days and 14 days of treatment,the histopathology of wound were observed by HE staining and the number of fibroblasts were counted.The levels of IL-1β,IL-18 and TNF-α in serum were detected by ELISA.The expression of autophagy-related protein Beclin-1 and LC3Ⅱ in granulation tissue was detected by immunohistochemistry.The expression of NLRP3,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),Caspase1,Pro-Caspase1 and Akt/mTOR autophagy pathway-related proteins Akt,p-Akt,mTOR and p-mTOR were detected by Western Blot.Results Compared with the blank control group,the pathological wound repair of the model group was delayed on the 7th day and 14th day,the number of fibroblasts per unit area was decreased(P<0.01).The levels of IL-1β,IL-18 and TNF-α were increased(P<0.01).The expression levels of ASC,Pro-Caspase1,Caspase1,and NLRP3 were increased in the wound tissues(P<0.01),while the expression levels of Beclin-1,LC3-Ⅱ,mTOR,p-mTOR,Akt and p-Akt were decreased in the wound tissues(P<0.01).Compared with the model group,the pathological injury in Chonghe soft extract group and growth factor group was significantly improved on the 7th day and 14th day.The number of fibroblasts per unit area was significantly increased(P<0.01).The levels of IL-1β,IL-18 and TNF-α were significantly decreased(P<0.01).The expression levels of ASC,Pro-Caspase1,Caspase1,and NLRP3 in the wound tissues were decreased(P<0.01),while the expression levels of Beclin-1,LC3-Ⅱ,mTOR,p-mTOR,Akt and p-Akt were increased(P<0.01,P<0.05).Conclusion Chonghe soft extract can reduce inflammatory reaction,promote the generation of fibro,regulate the Akt/mTOR-mediated NLRP3 inflammasome inactivation,improve the level of autophagy in wound,and promote ulcer wound healing in diabetic rats.

Supracondylar humerus fractures represent the most prevalent type of upper limb fractures in pediatric patients. As a result of the interplay of external forces, muscular contractions, and periosteal reactions, these fractures are prone not only to axial displacement but also to rotational displacement in a certain degree. Rapid and accurate assessment of the rotational displacement holds a paramount importance for intraoperative realignment, choice of fixation modalities, and anticipation of postoperative function. Currently, methods to evaluate the rotational displacement involve X-ray, CT, and ultrasound, but the various assessment techniques and criteria often pose challenges in differentiation. This paper reviews the current diverse imaging modalities for assessment of the rotational displacement, aiming to translate the intricate three-dimensional spatial rotation into single-plane rotations within the coronal, sagittal, and horizontal planes, thereby aspiring to furnish those concerned with clinical guidance.

Objective To investigate the expression and potential diagnostic value of six-transmembrane epithelial antigen of prostate 1(STEAP1)in bladder transitional cell carcinoma.Methods 52 patients with transitional cell carcinoma of the bladder who underwent surgical treatment at the 940th Hospital of Joint Lo-gistics Support Force of the Chinese People's Liberation Army from June 2021 to December 2022 were select-ed as the observation group.In addition,52 patients with benign tumors of the bladder who matched basic clin-ical data such as age,gender,and disease incidence were selected as the control group.The relative expression levels of STEAP1 and STEAP1 mRNA in bladder tumor tissues of patients in the two groups were deter-mined by enzyme-linked immunosorbent assay and real-time fluorescence quantitative PCR,and the relative expression levels of STEAP1 and STEAP1 mRNA in bladder tumor tissues of patients with different patho-logical parameters were compared.Spearman correlation analysis and binary Logistic regression analysis were used to screen the risk factors for the occurrence and clinical stage of bladder transitional cell carcinoma.Re-ceiver operating characteristic(ROC)curve and area under the curve(AUC)were used to evaluate the diagnos-tic and predictive value of each indicator for bladder transitional cell carcinoma.Results The relative expres-sion levels of STEAP1 and STEAP1 mRNA in bladder tumor tissues in observation group were significantly higher than those in control group,with statistical significance(P＜0.05).The relative expression levels of STEAP1 and STEAP1 mRNA in bladder tumor tissues of patients with middle and advanced bladder transi-tional cell carcinoma were significantly higher than those of patients with early bladder transitional cell carci-noma,with statistical significance(P＜0.05).Binary Logistic regression analysis showed that the relative ex-pression level of STEAP1 and STEAP1 mRNA in bladder tumor tissues of patients were independent risk fac-tors for the development of bladder transitional cell carcinoma and middle and advanced bladder transitional cell carcinoma(P＜0.05).ROC curve analysis showed that the AUC of STEAP1 and STEAP1 mRNA inde-pendently predicting the occurrence of bladder transitional cell carcinoma was 0.841(95％CI:0.760-0.922,P＜0.001)and 0.936(95％CI:0.893-0.980,P＜0.001),respectively,both of which had high predictive ef-ficacy.Conclusion The relative expression levels of STEAP1 and STEAP1 mRNA in bladder tumor tissues of patients are positively correlated with the occurrence of bladder transitional cell carcinoma and the middle and advanced bladder transitional cell carcinoma,suggesting that STEAP1 can be used as a potential marker for di-agnosis and prediction of the occurrence and development of bladder transitional cell carcinoma.

Objective:To investigate the clinical application value of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area.Methods:Twenty-six patients who underwent laparoscopic cholecystectomy based on the concept of enhancing recovery after surgery using the LEER model in People's Hospital of Jinkouhe District of Leshan from January to October 2021 were included in the observation group. An additional 20 patients who concurrently underwent laparoscopic cholecystectomy and conventional intervention were included in the control group. Clinical efficacy, postoperative complications and postoperative pain were compared between the two groups.Results:Postoperative fasting time, length of hospital stay, and total hospital days in the observation group were 6 (6, 6) hours, 2 (2, 3) days and 4 (4, 6) days respectively, which were significantly shorter than 24 (24, 36) hours, 5 (5, 6) days, 7 (7, 9) days in the control group ( H = 351.00, 407.50, 458.00, all P < 0.05). Hospitalization cost in the observation group was 5 454.58 (5 014.11, 6 016.58) yuan, which was significantly lower than 6 611.91 (6 192.68, 7 841.73) yuan in the control group ( H = 420.00, P < 0.05). There were no significant differences in operative time and postoperative complications between the two groups (both P > 0.05). At postoperative 6 hours, Visual Analogue Scale score in the observation group was 3 (3, 4) points, and patients with mild pain accounted for 73.07% (19/26). At postoperative 24 hours, Visual Analogue Scale score in the observation group was 2 (2, 3) points, and patients with mild pain accounted for 92.31% (24/26). Overall pain was well controlled after surgery. Patient satisfaction rate in the observation was 96.15% (25/26). All patients recovered and were discharged. Conclusion:Application of enhanced recovery after surgery using the LEER model in patients subjected to laparoscopic cholecystectomy in basic hospitals of Yi nationality area can promote postoperative recovery, contribute to changing the theory of diagnosis and treatment, and improve overall medical quality. The enhanced recovery after surgery protocol using the LEER model has a good application value.

This article aims to comprehensively review the concept, etiology, classification, classical cortical mapping, assessment, a proposed flowchart for the diagnosis and differential diagnosis, treatment, rehabilitation, mechanisms of development and recovery, prognosis, and influencing factors for post-stroke aphasia(PSA)types in the Chinese language.We emphasize the necessity and significance of neuroimaging assessment of the brain and blood vessels and neuropsychological assessment in the diagnosis and differential diagnosis of PSA in Chinese.We also recommend and encourage the use of the dichotomies of internal vs.external and anterior vs.posterior as a starting point, based on the association of anatomical locations of the brain and blood vessels with brain language areas and language disorders.A classification system of PSA in Chinese developed from this approach in the form of a flowchart is well-suited for guiding the clinical treatment of cerebral stroke.Incorporating the "four elements" , the flowchart enables convenient diagnosis, classification and differential diagnosis of PSA in Chinese and facilitates targeted and personalized rehabilitation planning to benefit the patient.This article introduces the use of memantine, piracetam, donepezil and other drugs for PSA treatment, evaluates clinical trials on memantine conducted in China and abroad and its mechanisms of action for the treatment of PSA, and discusses how rehabilitation therapy achieves therapeutic effects.For the treatment of PSA, clinical research and practice using drugs such as memantine, piracetam and donepezil in combination with non-pharmacotherapy and rehabilitation training should be promoted.

Objective:To explore the current situation of motoric cognitive risk syndrome (MCR) in the community elderly in Taiyuan and analyze its influencing factors.Methods:From January to April 2021, convenience sampling was used to select 500 elderly people from 5 communities in Taiyuan as the research object. The elderly were investigated with the General Information Questionnaire, Mini-Mental State Examination (MMSE) , simplified Geriatric Depression Scale-15 (GDS-15) , Short-Form Mini Nutritional Assessment (MNA-SF) and Lubben Social Network Scale-6 (Lubben-6) , and 4-meter walk test.Results:A total of 500 questionnaires were distributed, and 492 valid questionnaires were recovered, with a valid recovery rate of 98.40%. The prevalence of MCR among 492 community elderly people in Taiyuan was 11.38% (56/492) . Univariate analysis showed that there were statistically significant differences in the incidence of MCR among the community elderly in Taiyuan with different age, education level, obesity, living alone, number of diseases, diabetes, coronary heart disease, stroke, number of medications, chronic pain, nutritional status, depression and social isolation ( P<0.05) . Logistic regression analysis showed that educational level, obesity, diabetes, chronic pain, nutritional status, depression, and social isolation were the influencing factors of MCR in the elderly in Taiyuan ( P<0.05) . Conclusions:The incidence of MCR among the elderly in Taiyuan is high. Individualized interventions should be formulated according to the influencing factors to prevent or delay the occurrence of MCR in the community elderly.
