Objective To explore the efficacy and safety of omalizumab in the treatment of allergic bronchopulmonary aspergillosis(ABPA).Methods The clinical data of 26 ABPA patients treated with omalizumab in Zhongshan Hospital,Fudan University from November 2018 to December 2023 and 24 ABPA patients treated with prednisone combined with itraconazole in the same period were analyzed retrospectively.The primary outcomes were exacerbation times and oral corticosteroid-sparing effect.The secondary outcomes were respiratory symptoms,circulating eosinophil count,total immunoglobin E(IgE)level,specific IgE for aspergillus,pulmonary function(the percentage value of forced expiratory volume in one second predicted[FEV1%pred]),fraction of exhaled nitric oxide(FeNO),thoracic computed tomography(CT)manifestation and adverse reactions.Results In omalizumab group,the exacerbation times of ABPA after 6 and 12 months of treatment were 0(0,0)times/6 months and 0(0,1)times/6 months,there was no significant difference(P=0.157),which were significantly lower than those of the baseline(1[1,2]times/6 months,P＜0.001).The oral dose of prednisone decreased from 10(5,15)mg/d(before treatment)to 3.125(0,5)mg/d(6 months after treatment,P＜0.001).After 12 months of treatment,the oral dose of prednisone was 0(0,3.125)mg/d,which was significantly lower than that of the baseline dose(P=0.003).After treatment with omalizumab for 12 months,the FeNO level decreased significantly(26[13,36]×10﹣9 vs 30[18,56]×10﹣9,P=0.049).There was no significant difference in blood eosinophil count,total IgE level,specific IgE for aspergillus and FEV1%pred before and after omalizumab treatment.After 6 months of treatment with omalizumab,respiratory symptoms were relieved in 23 patients(88.5%)and radiographic improvement was achieved in eight out of sixteen patients(50%)with mucus plugs.More patients successfully discontinued oral prednisone when treated with omalizumab for 12 months than those in control group(P=0.035).During the treatment of omalizumab,4(15.4%)patients had a slight increase in alanine aminotransferase(ALT),and 1 patient was complicated with hepatocellular carcinoma during follow-up.Conclusions Omazumab treatment can effectively reduce the number of acute episodes of ABPA,reduce the dosage of oral glucocorticoids,improve FeNO,facilitate the absorption of mucus plugs,and has high safety.

Objective:To compare the short-term efficacy of laparoscopic sleeve gastrectomy (LSG) combined with sharp His angle reconstruction (LSG-His) versus traditional LSG.Methods:In this retrospective cohort study we collected clinical data of patients with obesity who had undergone LSG or LSG-His in the Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University, from January to June 2022. After excluding patients with incomplete follow-up data and those with hiatal hernia, 83 obese patients, of which 39 who had undergone LSG (LSG group) and 44 who had undergone LSG-His (LSG-His group), were included in the study. The basic steps in LSG-His are the same as in conventional LSG. After continuous suturing of the gastric staple line, one stitch is placed between the proximal side of the gastric greater curvature staple line and the proximal side of the gastric fundus posterior wall with the left diaphragm, and another stitch between the right side of the gastric fundus and the esophagus, reconstructing the sharp His angle. Clinical data, postoperative complications, and follow-up data on weight loss and gastroesophageal reflux disease (GERD) symptoms 1-, 3-, 6-, and 12-months post-discharge were compared between the two groups. GERD symptoms were assessed using the Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire.Results:There were no significant differences between the two groups in baseline characteristics, length of hospital stay, hospitalization costs, intraoperative bleeding, postoperative nausea and vomiting, dysphagia, or postoperative complications (all P>0.05). Compared with the LSG group, the LSG-His group had significantly longer operative times (92 [80, 100] minutes vs. 80 [70, 100] minutes, U=2.227, P=0.026), higher postoperative 24-hour pain scores (5.2±1.8 vs. 4.3±1.9, t=-2.065, P=0.041), and higher rates of morphine use (70.5% [31/44] vs. 46.2% [18/39], χ2=4.519, P=0.025). The incidence of new-onset GERD 12 months postoperatively was significantly lower in the LSG-His than the LSG group (10.7% [3/28] vs. 61.3% [19/31], χ2=14.00, P<0.001). According to changes in Gastroesophageal Reflux Disease Questionnaire and Reflux Diagnostic Questionnaire scores, the LSG-His group also had significantly lower rates of exacerbation of GERD (2/16 vs. 5/8, χ2=4.27, P=0.021) and higher rates of GERD remission (12/16 vs. 2/8, χ2=3.62, P=0.032) than did the LSG group. Additionally, excess weight loss rates were significantly higher in the LSG-His group at 3 months [(54.7± 18.7)% vs. (46.5±15.0)% , t=-2.166, P=0.033], 6 months [(73.8±24.7)% vs. (64.0±19.1)% , t=-2.018, P=0.047], and 12 months [(82.9±26.7)% vs. (72.2±19.3)%, t=-2.063, P=0.042] than in the LSG group. Conclusion:Compared with LSG, LSG-His is safe and feasible and achieves better short-term control of postoperative GERD and more effective weight loss. Further large-scale, long-term, prospective studies are needed to confirm the long-term efficacy of LSG-His.

OBJECTIVES: To investigate the clinical phenotypes, genetic characteristics, and pathological features of children with disorders of sex development (DSD). METHODS: A retrospective analysis was conducted on epidemiological, clinical phenotype, chromosomal karyotype, gonadal pathology, and genotype data of 165 hospitalized children with DSD at Children's Hospital of Hebei Province and Tangshan Maternal and Child Health Hospital from August 2008 to December 2022. RESULTS: Among the 165 children with DSD, common presenting symptoms were short stature (62/165, 37.6%), clitoromegaly (33/165, 20.0%), cryptorchidism (28/165, 17.0%), hypospadias (24/165, 14.5%), and skin pigmentation abnormalities/exteriorized pigmented labia majora (19/165, 11.5%). Chromosomal karyotype analysis was performed on 127 cases, revealing 36 cases (28.3%) of 46,XX DSD, 34 cases (26.8%) of 46,XY DSD, and 57 cases (44.9%) of sex chromosome abnormalities. Among the sex chromosome abnormal karyotypes, the 45,X karyotype (11/57, 19%) and 45,X/other karyotype mosaicism (36/57, 63%) were more common. Sixteen children underwent histopathological biopsy of gonadal tissues, resulting in retrieval of 25 gonadal tissues. The gonadal tissue biopsies revealed 3 cases of testes, 3 cases of dysplastic testes, 6 cases of ovaries, 11 cases of ovotestes, and 1 case each of streak gonad and agenesis of gonads. Genetic testing identified pathogenic/likely pathogenic variants in 23 cases (23/36, 64%), including 12 cases of 21-hydroxylase deficiency congenital adrenal hyperplasia caused by CYP21A2 pathogenic variants. CONCLUSIONS Short stature, clitoromegaly, cryptorchidism, hypospadias, and skin pigmentation abnormalities are common phenotypes in children with DSD. 45,X/other karyotype mosaicism and CYP21A2 compound heterozygous variants are major etiological factors in children with DSD. The most commonly observed gonadal histopathology in children with DSD includes ovotestes, ovaries, and testes/dysgenetic testes.

AIM:To observe the clinical efficacy of modified Buyang Huanwu Decoction in treating non-proliferative diabetic retinopathy(NPDR)of qi and yin deficiency and stagnation of collaterals, and to quantitatively analyze the changes in peripapillary vessel density before and after treatment using optical coherence tomography angiography(OCTA).METHODS:A randomized controlled trial was used to collect a total of 58 patients(99 eyes)with qi and yin deficiency and stagnation of collaterals NPDR who visited our hospital from June 2022 to November 2022, and patients were randomly divided into an observation group(n=29, 51 eyes)and a control group(n=29, 48 eyes). The control group received basic treatment according to the recommendations for DR published by the American Academy of Ophthalmology in 2019(blood glucose control, diabetes health education, and regular follow-up for patients with mild NPDR; and add local/grid-like laser photocoagulation if necessary for patients with moderate NPDR), while the observation group received modified Buyang Huanwu Decoction in addition to the basic treatment for 1mo. The best-corrected visual acuity(BCVA), traditional Chinese medicine(TCM)efficacy, peripapillary telangiectasia vessel density(ppVD), and changes in peripapillary retinal nerve fiber layer(pRNFL)thickness were compared between the two groups before and after treatment.RESULTS:The BCVA(LogMAR)of the observation group was 0.20(0.10, 0.30)after 1mo of treatment, which was significantly improved compared with that of the control group of 0.30(0.20, 0.40; P<0.05). The TCM efficacy in the observation group after 1mo of treatment was better than that in the control group(P<0.05). The ppVD in all quadrants of the observation group showed a significant improvement at 1mo after treatment, and the ppVD in all quadrants of the observation group was higher than that of the control group(P<0.05). The pRNFL thickness in the superior, temporal, and average peripapillary areas of the observation group increased after 1mo of treatment, and the pRNFL thickness in the superior, temporal, inferior quadrants, and average peripapillary area of the observation group was higher than that of the control group(P<0.05).CONCLUSION:Modified Buyang Huanwu Decoction can improve visual acuity and enhance TCM efficacy in patients with NPDR of qi and yin deficiency and stagnation of collaterals. It may be related to its ability to improve ppVD and reduce damage to the pRNFL.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.
