Objective:To determine the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema using Mendelian randomization (MR) analyses.Methods:This study was a secondary data analysis based on the summary data of genome-wide association studies (GWAS), which involved 293 723 participants (educational attainment) from the Social Science Genetics Association Consortium and 462 013 participants [allergic rhinitis and (or) eczema] from the UK Biobank. Genetic variants that were closely related to educational attainment were identified as instrumental variables. Two-sample MR analyses, including inverse-variance weighted (IVW), MR-Egger regression, weighted median method and weighted model-based estimation, were performed to investigate the causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, in which the odds ratio ( OR) values were used as indicators. Results:A total of 70 single-nucleotide polymorphisms (SNPs) were chosen as instrumental variables. The MR-Egger regression results suggested that the genetic pleiotropy was unlikely to bias our results ( P=0.107). In the univariable MR analyses, IVW regression showed that the risk of allergic rhinitis and (or) eczema was OR=1.044 (95% CI: 1.020-1.069, P<0.001) and OR=1.170 (95% CI: 1.074-1.256, P<0.001), respectively, for the increase in the duration of education by one year or one standard deviation ( SD) (3.71 years). In the reverse MR analysis, IVW regression showed little evidence that allergic rhinitis and (or) eczema affected educational attainment ( OR=1.020, 95% CI: 0.927-1.023, P=0.683). The results of the weighted median method and weighted mode-based estimation were consistent with the results of IVW. Conclusion:This study suggests that there is a positive causal relationship between educational attainment and the risk of allergic rhinitis and (or) eczema, which means that educational attainment can increase the occurrence of allergic rhinitis and (or) eczema.

It is believed that wind pathogen is one of the core pathogenic factors of small cell lung cancer （SCLC）. The nature and pathogenic characteristics of wind pathogen are closely related to the occurrence and metastasis of SCLC. Mainly manifested as deficiency of both qi and yin， healthy qi deficiency of SCLC makes it susceptible to invasion of external wind. Simultaneously， there are internal wind pathogenesis such as yin deficiency causing wind， blood deficiency causing wind， phlegm， stasis and toxin causing wind， liver yang transforming into wind. The internal and external winds together lead to the disease. Therefore， it is proposed to treat SCLC from wind theory， that is， boosting qi and nourishing yin to extinguish wind with taizishen （Radix Pseudostellariae）， wuweizi （Fructus Schisandrae Chinensis） and others； resolving phlegm and moving stasis to dispel wind with wind-dispelling and phlegm-resolving medicinals such as jiangcan （Bombyx Batryticatus）， muhudie （Semen Oroxyli）， fangfeng （Radix Saposhnikoviae）， tianma （Rhizoma Gastrodiae）， quanxie （Scorpio） and blood-invigorating and wind-dispelling medi-cinals such as danggui （Radix Angelicae Sinensis）， chuanxiong （Rhizoma Chuanxiong） and danshen （Radix et Rhizoma Salviae Miltiorrhizae）； attacking toxin and dissipating masses to dispel wind with shuizhi （Hirudo）， dilong （Pheretima）， fengfang （Nidus Vespae）， quanxie， baihuashe （Agkistrodon）， jiuxiangchong （Aspongopus） and other drastic medicinals； calming liver and extinguishing wind to prevent brain metastasis of SCLC with Tianma Gouteng Beverage （天麻钩藤饮） modification.

Objective:To compare the efficacy and safety of omacycline with meropenem plus linezolid in the treatment of patients with pulmonary infection.Methods:The clinical data of 58 patients with pulmonary infection admitted to the First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou Red Cross Hospital and Jiande First People’s Hospital from December 2021 to May 2022 were retrospectively analyzed. The patients were divided into the omacycline group ( n=29) and the meropenem combined with linezolid group (combined group, n=29). The omacycline group was given intravenous omacycline 200 mg or 100 mg, q. d, and the combined group was given intravenous meropenem (1 000 mg, t.i.d) and linezolid (600 mg, b. i.d). The clinical efficacy and drug-related adverse events of two groups were observed. SPSS 22.0 statistical software was used for data analysis. Results:In the omacycline group, 8 cases (27.6%, 8/29) were cured, 19 cases (65.5%, 19/29) were improved, and 2 cases (6.9%, 2/29) were worsened. In the combined group, 1 case (3.4%, 1/29) was cured, 26 cases (89.7%, 26/29) were improved, and 2 cases (6.9%, 2/29) died. There was a statistically significant difference between the two groups ( χ2=6.533, P=0.038). The respiratory failure occurred in 3 cases (10.3%, 3/29) of the omacycline group and 5 cases (17.2%, 5/29) of the combined group ( χ2=0.580, P=0.446). In those patients who were cured or improved, the median time from treatment initiation to disease remission was 3.0 (2.0, 5.5) d in the omacycline group and 5.0 (4.0, 6.0) d in the combined group ( Z=-2.122, P=0.034). There was no significant difference in the incidence of adverse reactions between the two groups [6.9% (2/29) vs. 13.8% (4/29), χ2=0.744, P=0.389]. Conclusion:Omacycline exhibits a good efficacy and safety in the treatment of patients with pulmonary infection, which may be prioritized for the treatment of pulmonary infections.

Objective To evaluate the safety of immediate breast reconstruction using deep inferior epigastric perforator (DIEP) flaps in the patients after neoadjuvant treatment. Methods From January 2019 to February 2021, the data of patients with breast cancer undergoing total mastectomy and immediate breast reconstruction using DIEP flap in Comprehensive Breast Health Center, Department of General Surgery, Ruijin Hospital were collected. Comparison of clinicopathological features was done between neoadjuvant treatment group and control group. Univariate analysis was used to compare the rate of surgical complications between two groups. Results A total of 110 patients were enrolled with 23 cases (20.9%) in neoadjuvant treatment group and 87 cases (79.1%) in control group. None of carcinoma in situ (0 vs. 19.5%, P=0.003) and higher pTNM stage (P<0.001) was present in neoadjuvant treatment group compared with those in control group. However, there were no significant differences in the number of flap perforator of DIEP (P=0.472), the proportion of bipedicled flaps (P=0.489), operative time (P=0.651) and hospital length of stay (P=0.275) between two groups. No significant difference was found in the incidence of postoperative complications between two groups. Breast seroma was the most common recipient complication (13.0%, 3 cases) without donor complication in neoadjuvant treatment group. The most common complication was fat necrosis (12.6%, 11 cases) in recipient site and abdominal seroma (3.4%, 3 cases) in donor site of control group. Reoperation was done in one case (4.3%) of neoadjuvant treatment group and 4 cases (4.6%) of control group. DIEP flap necrosis with total flap loss occurred in 2 cases (2.3%) in control group, but none in neoadjuvant treatment group. Conclusions The imme-diate breast reconstruction with epigastric free flap for breast cancer patients after neoadjuvant treatment would be a safe surgical scheme.
