Aural vertigo frequently encountered in the otolaryngology department of traditional Chinese medicine （TCM） mainly involves peripheral vestibular diseases of Western medicine， such as Meniere's disease， benign paroxysmal positional vertigo， vestibular neuritis， and vestibular migraine， being a hot research topic in both TCM and Western medicine. Western medical therapies alone have unsatisfactory effects on recurrent aural vertigo， aural vertigo affecting the quality of life， aural vertigo not relieved after surgery， aural vertigo with complex causes， and children's aural vertigo. The literature records and clinical practice have proven that TCM demonstrates unique advantages in the treatment of aural vertigo. The China Association of Chinese medicine sponsored the "17th youth salon on the diseases responding specifically to TCM： Aural vertigo" and invited vertigo experts of TCM and Western medicine to discuss the difficulties and advantages of TCM diagnosis and treatment of aural vertigo. The experts deeply discussed the achievements and contributions of TCM and Western medicine in the diagnosis and treatment of aural vertigo， the control and mitigation of the symptoms， and the solutions to disease recurrence. The discussion clarified the positioning and advantages of TCM treatment and provided guidance for clinical and basic research on aural vertigo.

【Objective】 To analyze the association of sexual development characteristics and phases with the cognitive and behavioral development of adolescents aged 10 to 14 in rural areas of Shaanxi Province, in order to provide scientific reference for enhancing adolescent health. 【Methods】 The study population was selected from a birth cohort study′s follow-up data for the adolescent phase. The Tanner quintile method was used to assess sexual development, the Wechsler Intelligence Scale for Children, Fourth Edition (WISC-Ⅳ) was used to assess cognitive development, and the Youth Self-Rating Scale(YSR-2001) was used to assess behavioral development. Generalized linear models was used to examine the association of the stages of adolescent sexual development with their cognitive and behavioral development. 【Results】 A total of 1 887 adolescents were enrolled in this study, with 1 111 (58.9%) boys. The proportion of boys and girls who have started sexual development was 78.22% and 89.30%, respectively. The detection rate of behavioral problems in adolescents was 9.70%, with 11.80% in boys and 6.70% in girls, and the gender difference was significant (χ²=13.517, P<0.001). Compared to adolescents in Tanner stage Ⅰ, adolescents in stage Ⅲ had a higher total cognitive score of 2.19 (95%CI: 0.15 - 4.23), and a higher total score of 3.84 (95%CI: 0.85 - 6.83,P<0.05) in stages Ⅳ-Ⅴ. The detection rate of total behavioral problems of children in Tanner stages Ⅳ-Ⅴ was 2.63 times (95%CI:1.27 - 5.46,P<0.05) higher than that in stage Ⅰ. In boys, the rate of detection of internalizing problems was 3.96 times(95%CI:1.60 - 9.81,P<0.01) higher than that in stage Ⅰ, and the detection rate of internalizing problems was 2.88 times(95%CI:1.19 - 7.01,P<0.05) higher than that in stage Ⅰ. 【Conclusions】 There is a significant correlation of sexual developmental phrase with cognitive and behavioral development among adolescents aged 10 - 14 years in rural Shaanxi Province. The detection rate of adolescent behavioral problems increases with the increase of sexual development level and cognitive level, and there are significant gender differences.

【Objective】 To explore the impact of intrapartum antibiotic prophylaxis (IAP) on antibiotic resistance genes (ARGs) in the gut microbiota of infants up to 6 months of age and their longitudinal changes, in order to provide theoretical basis for the rational use of antibiotics and antibiotic resistance control. 【Methods】 Fecal samples were collected within 3 days, 2 months, and 6 months from a maternal and birth cohort conducted between January 2018 and June 2019. A panel of 6 common ARGs (aac(6′)-Ib, qnrS, blaTEM, ermB, mecA, tetM) were tested, the absolute abundance and positive detection rate by qPCR were calculated. Nonparametric and linear mixed model (LMM) analysis were used to assess the influence of IAP on the absolute abundance of antibiotic resistance genes and the longitudinal changes in their abundance at the three time points. 【Results】 A total of 157 samples from 65 singleton infants were analyzed, including 15 mothers (23.1%) who received IAP. The detection rate of ARGs was high in infants up to six months of age, and the abundance of ARGs tended to increase over time. IAP significantly increased the abundance of the mecA gene in the gut microbiota of vaginally delivered infants at 6 months of age (6.1±1.1 in the VDIAP group vs. 3.8±4.6 in the VDno-IAP group, P=0.046). Additionally, in cesarean section infants, there was a significant increase in the abundance of aac(6′)-Ib genes at 2 months (β=3.81, ,P<0.05), P<0.05] and 6 months of age (β=4.89, ,P<0.001), P<0.001) compared to 3 days of age. 【Conclusions】 The findings suggest that IAP can increase the abundance of ARGs in 6-month-old infants, and this effect is still significant after stratifying by delivery mode. Therefore, the rational and standardized use of intrapartum antibiotics may help reduce the development of antibiotic resistance.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.

Ménière's disease （MD） is an inner ear disease characterized by vertigo， tinnitus， hearing loss， and ear stuffiness. Modern therapies such as drugs， surgery， and vestibular function rehabilitation have limited effects in relieving the symptoms and reducing the recurrence. Traditional Chinese medicine （TCM） can alleviate the symptoms of MD with simple operation and mild adverse reactions while emphasizing psychological adjustment. The TCM treatment of MD is individualized depending on different stages and pathogenic factors. The internal treatment mainly targets phlegm， dampness， water， wind， fire， deficiency， and blood stasis. External interventions include acupuncture and moxibustion. This paper reviewed the published articles about the treatment of MD with TCM. In recent five years， the published studies were mainly clinical trials and experience discussion （or case reports）， and few reports of fundamental research were published. In these studies， the Western medicine diagnosis of MD mostly refers to the Diagnostic Basis and Efficacy Evaluation of Ménière's Disease （Guiyang， 2006） and the Guidelines for Diagnosis and Treatment of Ménière's Disease （2017）， while the TCM diagnosis mostly refers to the Criteria of Diagnosis and Therapeutic Effect of Diseases and Syndromes in Traditional Chinese Medicine issued by the National Administration of TCM in 1994. The efficacy was mostly evaluated based on clinical efficacy， scales， syndrome scores， pure tone audiometry， etc.， while caboratory indexes were rarely used. The available clinical studies about the treatment of MD with TCM generally have low quality of evidence and single intervention means. In the future， the research on the treatment of MD with TCM can be improved by standardizing the research program， improving the quality of evidence， exploring more intervention methods， and strengthening basic research.

Objective:To investigate the clinical efficacy of carbomer hemorrhoid gel in the treatment of second-degree internal hemorrhoid bleeding.Methods:A total of 160 anorectal outpatients with second-degree internal hemorrhoid bleeding who received treatment in Zhuhai Hospital of Integrated Traditional Chinese and Western Medicine from January 2017 to January 2021 were included in this study. They were randomly divided into an observation group and a control group ( n = 80/group). In the observation group, carbomer hemorrhoid gel was used to plug the anus, while in the control group, a hemorrhoid suppository was used to plug the anus. All patients were treated for 7 days. Clinical efficacy was compared between the two groups. Results:After 4 days of treatment, the bleeding score in the observation group was lower than that in the control group [1(0) point vs. 2(1) points, Z = -6.70, P < 0.05). After 7 days of treatment, the bleeding score in the observation group was significantly lower than that in the control group [0(1) point vs. 1(1) point, Z = -4.73, P < 0.05]. After 4 days of treatment, there was no significant difference in the size score of the hemorrhoids between the two groups ( P > 0.05). After 4 days of treatment, the size score of hemorrhoids in the control group did not differ significantly compared with before treatment ( P > 0.05). After 4 days of treatment, the size score of hemorrhoids in the observation group differed significantly compared with before treatment ( Z = -3.16, P < 0.05). After 7 days of treatment, the size score of the hemorrhoids in the observation group was lower than that in the control group [1(1) point vs. 1(0) point, Z = -4.48, P < 0.05]. The total response rate in the observation group was significantly higher than that in the control group [97.5% (78/80) vs. 75% (60/80), Z = -4.50, P < 0.05]. Conclusion:Carbomer hemorrhoid gel is a new drug used to treat hemorrhoids. It has a new dosage form, has no stimulation to the rectum, and is safe to use. Carbomer hemorrhoid gel is highly effective on second-degree internal hemorrhoid bleeding and deserves clinical popularization.

While neuroblastoma accounts for 15% of childhood tumor-related deaths, treatments against neuroblastoma remain scarce and mainly consist of cytotoxic chemotherapeutic drugs. Currently, maintenance therapy of differentiation induction is the standard of care for neuroblastoma patients in clinical, especially high-risk patients. However, differentiation therapy is not used as a first-line treatment for neuroblastoma due to low efficacy, unclear mechanism, and few drug options. Through compound library screening, we accidently found the potential differentiation-inducing effect of AKT inhibitor Hu7691. The protein kinase B (AKT) pathway is an important signaling pathway for regulating tumorigenesis and neural differentiation, yet the relation between the AKT pathway and neuroblastoma differentiation remains unclear. Here, we reveal the anti-proliferation and neurogenesis effect of Hu7691 on multiple neuroblastoma cell lines. Further evidence including neurites outgrowth, cell cycle arrest, and differentiation mRNA marker clarified the differentiation-inducing effect of Hu7691. Meanwhile, with the introduction of other AKT inhibitors, it is now clear that multiple AKT inhibitors can induce neuroblastoma differentiation. Furthermore, silencing AKT was found to have the effect of inducing neuroblastoma differentiation. Finally, confirmation of the therapeutic effects of Hu7691 is dependent on inducing differentiation in vivo, suggesting that Hu7691 is a potential molecule against neuroblastoma. Through this study, we not only define the key role of AKT in the progression of neuroblastoma differentiation but also provide potential drugs and key targets for the application of differentiation therapies for neuroblastoma clinically.

BACKGROUND: The Id2 gene is an endogenous negative regulator of basic helix-loop-helix factor, which is involved in the cell proliferation, differentiation and existence. Id2 also shows functional diversity in the progression and infiltration of different types of tumors OBJECTIVE: To observe the changes of proliferation and invasiveness of PC-3 human prostate cancer stem cells after shRNA-Id2 transfection. METHODS: PC-3 human prostate cancer stem cells in logarithmic growth phase were harvested to isolate tumor stem cell spheres by serum-free suspension culture. The expression of CD44+CD24-on the surface of tumor stem cells was detected by flow cytometry. The shRNA-Id2 expression vector was constructed and transfected into PC-3 human prostate cancer stem cells. Untransfected PC-3 human prostate cancer stem cells were used as control. At 48 hours after transfection, the expression of Id2 gene and protein in shRNA-Id2 transfected prostate cancer stem cells, NC-shRNA empty vector transfected prostate cancer stem cells and untransfected prostate cancer stem cells were detected by RT-PCR and western blot, respectively. The proliferation and invasion of shRNA-Id2 transfected prostate cancer stem cells and untransfected prostate cancer stem cells were detected by MTT assay and Transwell chamber, respectively. The expressions of E-cadherin, vimentin and Twist were detected by western blot and RT-PCR. RESULTS AND CONCLUSION: Tumor stem cell spheres were successfully isolated by the serum-free suspension culture. The expression rate of CD44+CD24-on the surface of the third-generation PC-3 human prostate cancer stem cells was (85.69±8.96) ％, indicating that the cultured tumor stem cell spheres overexpressed the phenotype of tumor stem cells. At 48 hours after transfection, the expression of Id2 gene and protein was significantly lower in the shRNA-Id2 transfection group than the non-transfection group (P < 0.05) , indicating that the expression of Id2 was successfully interfered with the expression of PC-3 prostate cancer stem cells. The invasive ability of the cells in the shRNA-Id2 transfection group was significantly lower than that in the non-transfection group (P < 0.05). Western blot and RT-PCR detection showed that the expression of E-cadherin, an epithelial marker of PC-3 prostate cancer stem cells, in the shRNA-Id2 transfection group was significantly higher than that in non-transfection group (P < 0.05) , while the expression of vimentin, a marker of mesenchymal stem cells, and Twist, a transcription factor regulating cell-mesenchymal transformation, in the shRNA-Id2 transfection group was significantly lower than that in the non-transfection group (P < 0.05). These findings indicate that RNA interference with Id2 gene can inhibit the proliferation and invasion of PC-3 prostate cancer stem cells by regulating the expression of E-cadherin, vimentin and Twist.

Objective To explore pathogenesis and influencing factors of poor outcome in patients with wake-up stroke.Methods In this prospective study,patients with acute ischemic stroke who were hospitalized in the Department of Neurology of the Second Affiliated Hospital of Xuzhou Medical University from October 2016 to December 2017 were continuously collected.All patients were divided into wake-up stroke group and non-wake-up stroke group according to the onset time.The clinical data of demographics,vascular risk factors,imaging examination,laboratory examination of the two groups were collected to identify the pathogenesis of wake-up stroke.Followed up to six months of onset,the patients were divided into poor outcome (modified Rankin Scale (mRS) score ＞2) and good outcome (mRS score 0-2) subgroups according to mRS score.Multivariate Logistic regression analysis was used to determine the influencing factors of poor outcome in patients with wake-up stroke.Results A total of 178 patients with acute ischemic stroke were enrolled in the study,including 42 patients (23.60％) in the wake-up stroke group and 136 patients (76.40％) in the non-wake-up stroke group.Followed up to six months of onset,11 patients lost,and 167 patients were followed up finally.There were 40 patients (23.95％) in the wake-up stroke group,including 17 patients (42.50％) with poor outcome and 23 patients (57.50％) with good outcome.There were 127 patients (45.64％) in the non-wake-up stroke group,including 32 patients (25.20％) with poor outcome and 95 patients (74.80％) with good outcome.The difference of poor outcome between the two groups was statistically significant (x2=4.393,P=0.036).Comparison of the demographic and baseline data of the wake-up stroke group and the non-wake-up stroke group showed that the differences between variables such as atrial fibrillation and double-dose hypertension were statistically significant.Univariate analysis showed that there were statistically significant differences in vascular risk factors,Trial of Org 10172 in Acute Stroke Treatment etiology,stroke severity,number of stroke lesions,treatment patterns,and number of cerebral microbleeds between the poor and good outcome subgroups.Multivariate Logistic regression analysis showed that the moderate to severe stroke (odds ratio (OR)=3.838,95％ confidence interval (Co 2.162-5.890,P=0.018),the number of lesions in cerebral microbleeds (OR=2.113,95％CI 1.291-2.868,P=0.049) were independent risk factors for poor outcome of wake-up stroke.Intravenous thrombolysis (OR=0.427,95％CI 0.242-0.615,P=0.036) was an independent protective factor for poor outcome of wake-up stroke.Conclusions The onset of wake-up stroke is closely related to atrial fibrillation and reverse scoop hypertension with higher incidence of poor outcome.Early adequate imaging screening and stroke severity assessment have important reference to guide clinical treatment and predict outcome.
