BackgroundIn recent years， the incidence of depression among adolescents has been increasing steadily， posing a serious threat to their physical and mental health and even leading to severe consequences such as self-harm and suicide. At the same time， the detection rate of subclinical depression symptoms among adolescents is even higher. Although these symptoms do not meet the clinical diagnostic criteria， they have significantly affected their quality of life， and their persistence over time may further develop into depression. Therefore， in-depth exploration of adolescent depression symptoms and the predictive factors holds significant practical significance and research value. However， up to now， no large-scale investigation and research on depression symptoms among children and adolescents has been conducted in Inner Mongolia Autonomous Region. ObjectiveTo understand the prevalence of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region， in order to provide references for formulating scientific and effective prevention strategies and intervention measures. MethodsBy using the cluster stratified random sampling method， 6 281 students from the third grade of primary school to the second grade of high school in 12 leagues and cities of Inner Mongolia Autonomous Region were selected in March 2024. A self-designed questionnaire and the Self-rating Depression Scale （SDS） were used for on-site investigation. ResultsA total of 6 058 （96.45%） children and adolescents completed the valid questionnaire survey， and 2 728 cases （45.03%） were found to have depressive symptoms. There were statistically significant differences in the detection rates of depressive symptoms among children and adolescents of different genders， ages， whether they were only children， different family types， family monthly income， parents' educational levels， and whether the mother was employed （χ²=33.769， 40.618， 48.593， 29.972， 142.648， 195.999， 168.190， 5.445， P<0.05 or 0.01）.The results of the Logistic regression analysis showed that for children and adolescents， being female， aged between 12 and 16， over 16 years old， not being an only child， living in a reconstituted family， having a monthly family income of less than 5 000 yuan， and having parents with an education level of primary school or below were predictors of depressive symptoms （OR=1.241， 1.427， 1.273， 1.177， 1.549， 1.278， 1.462， 1.417， 1.514， 1.929， 1.660， 1.528， P<0.05 or 0.01）. ConclusionThe detection rate of depressive symptoms among children and adolescents in Inner Mongolia Autonomous Region is relatively high. Factors that may predict depressive symptoms in children and adolescents include female gender， ages between 12 and 16， ages over 16 years old， non-only children， families with a restructured structure， monthly family income of less than 5 000 yuan， and parents with an education level of primary school or below. ［Funded by Science and Technology Planning Project of the Inner Mongolia Autonomous Region （number， 2022YFSH0119）］

Blood-bi-syndrome is primarily characterized by localized numbness and mild pain in the limbs.Records about the diagnosis and treatment of blood-bi-syndrome are scattered throughout classical medical literature.According to the theory of Yindan and Yangdan formulas in the classical prescription system,when the body's ascending function of qi movement is insufficiency,Yangdan formulas which contain Astragali Radix can be used for warming and uplifting yang qi.Conversely,when the descending function of qi movement is insufficiency,Yindan formulas which contain containing Bupleuri Radix can be used for astringing,descending,clearing and purging.This article,based on the principles of Yindan and Yangdan formulas,analyzed the fundamental pathogenesis of blood-bi-syndrome developing from the transmission of superficial syndromes,as well as its clinical manifestations during the transmission and change between taiyin disease and yangming disease.And the therapeutic strategies for blood-bi-syndrome were also summarized.It is proposed that taiyin blood-bi-syndrome arises in individuals with constitutionally deficient cold after the attack of pathogenic factors,resulting from fluid depletion,blood insufficiency,and stomach deficiency,which should be treated by Yangdan Formulas with pungent-sweet-warm properties for warming and uplifting yang qi.For the treatment of patients with taiyin blood-bi-syndrome characterized by exterior syndrome,Astragali Radix-containing classical prescriptions like Astragali Radix and Cinnamomi Ramulus Five-Component Decoction(Huangqi Guizhi Wuwu Decoction)can be chosen;for the treatment of patients with taiyin blood-bi-syndrome characterized by interior syndrome,Zingiberis Rhizoma Recens-containing classical prescriptions like Citri Reticulatae Pericarpium and Bambusae Caulis in Taenia Decoction(Jupi Zhuru Decoction)is adopted.Conversely,yangming blood-bi-syndrome occurs in individuals with constitutionally excessive heat after the attack of pathogenic factors,resulting from the internal accumulation of blood stasis and heat and the impairment of the fluid and blood,which should be treated by Yindan Formulas with pungent-sweet-cold or sour-cold properties for astringing,descending,clearing and purging.For the treatment of patients with yangming blood-bi-syndrome characterized by exterior syndrome,Puerariae Lobatae Radix-containing classical prescriptions like Phyllostachydis Henonis Folium and Puerariae Lobatae Radix Decoction(Zhuye Gegen Decoction)can be used;for the treatment of patients with yangming blood-bi-syndrome characterized by interior syndrome,Paeoniae Radix Alba-containing classical prescriptions like Rhei Radix et Rhizoma and Eupolyphaga seu Steleophaga Decoction(Dahuang Zhechong Wan)is recommended.

Objectives To evaluate the effectiveness and safety of peramivir trihydrate in patients with influenza.Methods This was a randomized,double-blind,double-dummy,placebo and positive control,multicenter clinical trial,comparing peramivir trihydrate with oseltamivir and placebo.The inclusive criteria were 15-70 years old,onset within 48 h,positive rapid influenza antigen test,and febrile(＞38℃) accompanied with at least two associated symptoms.The severe cases complicated with chronic pulmonary and cardiac diseases,malignancies,organ transplantation,hemodialysis,uncontrolled diabetes,immunocompromised status,pregnancy and coexistence of bacterium infections were excluded.All patients were randomized 2:2:1 to receive peramivir,oseltamivir and placebo respectively.The primary endpoint was the disease duration,the secondary endpoints included time to normal axillary temperature and normal living activities,viral response,and adverse effects.Results Following informed consent,133 patients were included in this study.Four patients were exclude due to missing medical records,not fitting inclusion or exclusion criteria and poor compliance.A total of 129 patients were finally analyzed,including 49 cases,54 cases and 26 cases in peramivir group,oseltamivir group and placebo group.The median disease duration were 96 (76,120)hours,105(90,124) hours,and 124 (104,172)hours in three groups respectively(P＞0.05).The time to normal axillary temperature,normal living activities and viral response were not significantly different in three groups(P＞0.05).Conclusion The value of antiviral therapy in patients with mild influenza needs to be further determined.

OBJECTIVE:To observe long-term efficacy of intensive rosuvastatin therapy in the treatment of acute coronary syn-drome (ACS) and explore its possible mechanism,so as to provide reference for clinical diagnosis and treatment. METHODS:ACS patients receiving rosuvastatin after cured in our hospital during Jan. 2013-Jan. 2015 were divided into observation group(55 cases)and control group(47 cases)according to the dose of rosuvastatin. Under same guidance of physicans,2 groups were addi-tionally given Rosuvastatin calcium tablets(20 mg for observation group,10 mg for control group,qd,po)orally on the basis of routine treatment. Both groups were treated for 1 year. The incidence of 1-year accumulative main adverse cardiac event (MACE) were compared between 2 groups as well as the levels of blood lipid and serum cytokines,the occurrence of ADR before treat-ment,after 3 months of treatment. RESULTS:The incidence of accumulative MACE in observation group was significantly lower than control group,with statistical significance (P<0.05). After treatment,the levels of TC and LDL-C in 2 groups were de-creased significantly;the level of LDL-C was inCreased significantly compared to before treatment,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). The levels of IL-1β and TNF-α in 2 groups were decreased significantly (P<0.05);the observation group was significantly lower than the control group,with statistical signifi-cance (P<0.05). The peripheral blood LDL-C was positively correlated with IL-1β and TNF-α in observation group after treat-ment,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Intensive rosuvastatin therapy can significantly improve the long-term prognosis for ACS patients,which may associate with lipid metabolic regulation and anti-inflammatory effect.

Objective To explore the risk factors of initial surgery and postoperative complications of Crohn's disease (CD).Methods The retrospective case-control study was conducted.The clinical data of 227 patients with CD who were admitted to the Cangzhou Central Hospital from April 2011 to July 2015 were collected.Treatment principles included reducing the clinical symptoms,promoting healing of intestinal mucosa under endoscopy,delaying CD progression and preventing intestinal exhaustion and related complications.The medication was performed in the early period.The resection of partial intestines was applied to patients if there was poor effect of medication or combined with intestinal obstruction,intestinal fistula,digestive tract perforation,abdominal abscess and complex anal fistula.Observation indicators:(1) treatment situation,(2) follow-up situation,(3) related factors analysis affecting initial surgery of patients with CD,(4) related factors analysis affecting postoperative complications of patients after initial surgery for CD.Follow-up using regular telephone interview and outpatient examination was performed up to May 2016.Follow-up included the wound infection,abdominal abscess,intestinal obstruction,anastomotic fistula and pulmonary infection.Measurement data with normal distribution were represented as-x ± s and comparison between groups was analyzed using the t test.Count data were represented as the proportion and analyzed by the chi-square test.The univariate analysis was done using the chi-square test and Kruskal-Wallis test,and multivariate analysis was done using the Logistic regression model.Results (1) Treatment situation:of 227 patients,68 underwent initial surgery and 159 didn't undergo surgery.The duration from diagnosis to initial surgery in 68 patients was (4.7 ± 2.5) months.Of 68 patients with surgery,28 received the emergency surgery and 40 received the selective surgery.Operation time and volume of intraoperative blood loss were (175 ±44) minutes and (285 ± 110) mL,respectively.The side-to-side anastomosis was conducted in 47 patients and non-side-to-side anastomosis in 21 patients.Other 159 patients without surgery received the medication of mesalazine,hydrocortisone,methotrexate and infliximab.(2) Follow-up situation:68 patients with initial surgery were followed up for 5-61 months,and 22 had postoperative complications.Of 9 patients with anastomotic fistula,6 had enterocutaneous fistula (5 patients with enterocutaneous fistula were improved by selective surgery,and the other patient was progress to acute diffuse peritonitis and then was improved by peritoneal lavage,adequate drainage and nutritional support therapy after emergency surgery).Three patients with anastomotic abscess were improved by adequate drainage.Six patients with secondary intestinal obstruction were improved by conservative treatment.Three patients with abdominal abscess were improved after antiinflammatory treatment and adequate drainage.Two patients with wound infection were improved by regular dressing change.Two patients with pulmonary infection were improved by anti-inflammatory and phlegm conservative treatment.(3) The related factors analysis affecting initial surgery of patients with CD.The results of univariate analysis showed that age of diagnosis,smoking history and behavior of disease were the related factors affecting initial surgery of patients with CD (Z =-2.120,x2 =5.082,50.512,P＜ 0.05).The results of multivariate analysis showed that A3 of age of diagnosis,B2 and B3 of pattern of disease were the independent risk factors affecting initial surgery of patients with CD [OR =15.624,10.535,28.509,95％ confidence interval (CI):4.856-29.375,3.609-17.637,8.526-79.228,P ＜ 0.05].(4) The related factors analysis affecting postoperative complications of patients after initial surgery for CD.The results of univariate analysis showed that preoperative levels of albumin (Alb) and hemoglobin (Hb),emergency surgery,operation time and anastomotic method were the related factors affecting postoperative complications of patients after initial surgery for CD (x2 =10.757,7.639,6.773,4.309,16.346,P ＜ 0.05).The results of multivariate analysis showed that preoperative Alb≤28 g/L,Hb≤ 100 g/L,emergency surgery and non-side-to-side anastomosis were the independent risk factors affecting postoperative complications of patients after initial surgery for CD (OR =9.592,8.849,6.538,12.645,95％CI:2.209-25.235,2.034-24.773,1.846-15.893,3.935-38.873,P ＜ 0.05).Conclusions The age of diagnosis ＞ 40 years,B2 and B3 of CD are high risk group of initial surgery.The poor preoperative nutritional status,emergency surgery and non-side-to-side anastomosis are independent risk factors affecting postoperative complications of patients after initial surgery for CD.
