Objective:To investigate the risk factors of wet ear status and its impact on the efficacy of endoscopic type Ⅰ tympanoplasty. Methods:A retrospective analysis was conducted at the Department of Otolaryngology Head and Neck Surgery, the First Affiliated Hospital of Chinese People's Liberation Army（PLA）Air Force Medical University, on 160 ears that underwent endoscopic type Ⅰ tympanoplasty; these were assigned to a dry-ear group （n= 118） and a wet-ear group （n= 42）.Univariate analysis and binary logistic regression were used to identify risk factors for wet ear status. Postoperative outcomes, including tympanic meoombrane healing rate and hearing improvement across frequencies, were compared between groups. Results:①Significant intergroup differences were observed in age, residual tympanic membrane status, external auditory canal condition, mastoid pneumatization（MC0）, and middle ear ventilation dysfunction（P<0.05）; ②The degree of mastoid pneumatization being MC0 is an independent risk factor for wet ear（P<0.05）; ③No significant difference in tympanic membrane healing rates was found（P>0.05）; ④The wet ear group showed significantly higher pre-and postoperative air-conduction（AC） and bone-conduction（BC） thresholds at 2 kHz and 4 kHz compared to the dry ear group（P<0.05）, though the postoperative air-bone gap（ABG） improvement was comparable. Conclusion:Poor mastoid pneumatization is a risk factor for wet ears. The wet ear state has no effect on tympanic membrane healing and air-bone conduction gap, but patients in the wet ear group may have more severe inner ear or auditory nerve pathway damage.

Acute urinary retention(AUR)occurs frequently among astronauts on orbit.The current treatment is complex and easy to damage the urethra,which seriously affects the life and work of astronauts.In contrast,acupuncture,a traditional Chinese remedy,has shown promising results in managing urinary retention.However,the specific acupoints that could potentially prevent AUR remain uncertain due to the unique physiological conditions experienced by individuals in space compared to those on Earth.To address this gap,our research delved into the mechanisms of AUR and acupuncture within both traditional Chinese medicine and modern medical practices.We conducted a thorough literature review from Pubmed,Web of Science,CNKI,Wanfang database,VIP database and Chinese Medical Code database.A hierarchical evidence-scoring approach was utilized to analyze the included literatures,thus devised acupuncture protocols for the treatment of AUR.The outcomes of our study aim to establish a foundation for the application of acupuncture in managing AUR.

Under the influence of long-term space flights and the confined space environment,it is very easy to induce space depression syndrome,mainly manifested as decreased emotional stability,sleep disorders,mental fatigue,etc.,which seriously affect the living conditions and working abilities of astronauts.The current treatment methods mainly focus on psychological support and drug intervention.Acupuncture has a good effect in treating depression.Therefore,starting from the TCM pathogenesis and modern medical pathogenesis of aerospace depression syndrome,we conducted literature retrieval from databases such as the Chinese Medical Classic,China National Knowledge Infrastructure(CNKI),Wanfang,VIP,PubMed,and Web of science.For the included literature,we adopted the stratified evidence scoring method and combined the TCM mechanism and modern medical mechanism of the effect of acupuncture.A prescription for acupuncture points was constructed to provide a basis for selecting acupuncture points for the prevention of aerospace depression syndrome through acupuncture.

Objective:To explore the influence of social exclusion on the relapse tendency of female drug re-hab patients,and the mediating role of self-esteem and the moderating role of positive psychological capital.Method:A total of 288 female drug rehabilitation patients were selected,and the Social Exclusion Question-naire(SEQ)was used to assess the degree of social exclusion experienced by the patients.The Relapse Tendency Questionnaire(RPQ)was used to evaluate the current tendency of drug relapse.The Rosenberg Self-Esteem Scale(RSES)was used to evaluate the self-esteem level of the patients,and the Positive Psychological Capital Question-naire(PPCQ)was used to evaluate their level of positive psychological capital.Results:The SEQ scores of female drug rehab patients were positively correlated with the RPQ scores(β=0.41,P＜0.001),The RSES scores had a mediating effect between the scores of SEQ and RPQ,with a mediation effect size of 0.09(95％CI:0.04-0.15,accounting for 20.6％of the total effect).The PPCQ scores had a moderating effect between the scores of RSES and RPQ(β=-0.08,P＜0.05)and between the scores of SEQ and RPQ(β=0.10,P＜0.05).Conclusion:So-cial exclusion could not only directly affect but also indirectly affect the relapse tendency through self-esteem of fe-male drug rehab patients.Positive psychological capital could moderate the relationship between social exclusion,self-esteem,and relapse tendency.

Astronauts are affected by the space environment,and there are health problems in many systems of the body,which seriously affect the on-orbit work efficiency and the health recovery after landing.Although measures have been taken,there are still deficiencies.Acupuncture can regulate the body in a multi-target,multi-level and multi-system way to protect the health of astronauts,which is an effective measure to protect the health problems of astronauts.But there is no acupoint group database for aerospace medical problems,which limits the application of acupuncture in space.The aim of this paper is to solve the possible aerospace medical problems of astronauts by acupuncture.Firstly,the acupuncture indications in aerospace medicine are determined through literature research,expert consultation and expert consensus,and then the evidence collection,evidence evaluation and evidence aggregation are carried out through the"stratified evidence evaluation method"for ancient literature,modern literature and expert experience.Finally,acupoint prescriptions were recommended based on the comprehensive score of acupoints,and acupuncture prescriptions for all acupuncture indications in aerospace medicine were integrated to form an acupoint group database,so as to contribute more Chinese wisdom and solutions to solve aerospace medicine problems.

Objective To evaluate the efficacy and safety of high intensity focused ultrasound(HFIU)combined with endometrial ablation in the treatment of adenomyosis(AM)patients with heavy menstrual bleeding(HMB).Method A total of 199 patients with AM combined with HMB who underwent HIFU treatment at the Obstetrics and Gynecology Center of Affiliated Hospital of Chengdu University of TCM from July 2020 to September 2022 were selected and divided into two groups according to the ablation range.The combined ablation group included 80 cases with lesion and endometrial ablation(endometrial ablation rate≥30%),while the lesion ablation group 119 cases with simple lesion ablation.A 1∶1 propensity score matching was performed on the two groups,resulting in 59 patients in each group.A 6-month follow-up was conducted.The clinical manifestations(menstrual volume,degree of dysmenorrhea,uterine and lesion volume),quality of life(MS-QOL,UFS-QOL),and postoperative adverse reactions between the two groups before and 6 months after surgery was compared.Results Menstrual volume,degree of dysmenorrhea,uterine and lesion volume,MS-QOL score,and UFS-QOL score of the both groups were improved 6 months after surgery,when compared to those before surgery(P<0.05).Significantly reduced menstrual volume,degree of dysmenorrhea,and lower MS-QOL score were observed in the combined ablation group when compared with the lesion ablation group(P<0.05),but there was no statistical significance in uterine and lesion volume and UFS-QOL score(P>0.05).There was no difference in the incidence of adverse reactions between the two groups(P>0.05),but the combined ablation group had longer vaginal bleeding and fluid flow time(P<0.05).Conclusion The combined HIFU and endometrial ablation can effectively reduce menstrual flow,alleviate dysmenorrhea,and improve quality of life in patients with AM combined with HMB.Although it increases vaginal bleeding and fluid flow time,reasonable symptomatic management can effectively prevent the occurrence of adverse consequences such as infection.

Objective: To examine the association of pre-pregnancy body mass and weight gain during pregnancy with macrosomia. Methods: From January 2015 to December 2015, a total of 20 477 pregnant women were recruited by probabilistic proportional scale sampling with simple randomization in Sichuan, Yunnan and Guizhou Provinces. Basic information of pregnant women, weight gain during pregnancy and weight of newborn were collected. A multiple logistic regression model was used to assess the association between the pre-pregnancy body mass and gestational weight gain indicators with macrosomia. Results: 20 321 mother-infant were included in the final analysis. 20 321 pregnant women were (30.09±4.10) years old and delivered at (39.20±1.29) weeks, among which 12 341 (60.73%) cases were cesarean delivery. The birth weight of 20 321 infants were (3 292.26±431.67) grams, and 970 (4.77%) were macrosomia. The multiple logistic regression model showed that after adjusting for the age of women, compared to the normal weight group in the pre-pregnancy, the overweight and obesity group elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.69−2.35) and 4.05 (95%CI: 3.05−5.39), respectively. After adjusting for the age, the pre-pregnancy BMI, delivery weeks, delivery mode and infant′s gender, compared to the weight-gain appropriate group, higher weight gain rate in the mid-pregnancy and excessive total gestational weight gain elevated the risk of macrosomia, with OR (95%CI) about 1.99 (95%CI: 1.66−2.39) and 1.80 (95%CI: 1.55−2.08), respectively. Conclusion The overweight before pregnancy, obesity before pregnancy, the rate of weight gain in the second trimester and the high total weight gain during pregnancy could increase the risk of macrosomia.
