OBJECTIVE: To examine the effectiveness of Chinese medicine (CM) Lianhua Qingwen Granule (LHQW) and Jingyin Gubiao Prescription (JYGB) in asymptomatic or mild patients with Omicron infection in the shelter hospital. METHODS: This single-center retrospective cohort study was conducted in the largest shelter hospital in Shanghai, China, from April 10, 2022 to May 30, 2022. A total of 56,244 asymptomatic and mild Omicron cases were included and divided into 4 groups, i.e., non-administration group (23,702 cases), LHQW group (11,576 cases), JYGB group (12,112 cases), and dual combination of LHQW and JYGB group (8,854 cases). The length of stay (LOS) in the hospital was used to assess the effectiveness of LHQW and JYGB treatment on Omicron infection. RESULTS: Patients aged 41-60 years, with nadir threshold cycle (C_T) value of N gene <25, or those fully vaccinated preferred to receive CM therapy. Before or after propensity score matching (PSM), the multiple linear regression showed that LHQW and JYGB treatment were independent influence factors of LOS (both P<0.001). After PSM, there were significant differences in LOS between the LHQW/JYGB combination and the other groups (P<0.01). The results of factorial design ANOVA proved that the LHQW/JYGB combination therapy synergistically shortened LOS (P=0.032). CONCLUSIONS Patients with a nadir C_T value <25 were more likely to accept CM. The LHQW/JYGB combination therapy could shorten the LOS of Omicron-infected individuals in an isolated environment.

Objective:To investigate the clinical characteristics and genetic etiology of Duchenne muscular dystrophy (DMD) with myogenic tumors.Methods:The clinical data of 2 children with DMD combined with myogenic tumors diagnosed in Children′s Hospital Affiliated to Zhengzhou University in July 2021 and February 2022 were collected. The relevant literature was reviewed to summarize the clinical characteristics and explore the mechanism of the dystrophin ( DMD) gene in myogenic tumors. Results:A 6-year and 10-month-old boy with DMD (deletion of exon 45) and a 12-year-old boy with DMD (deletion of exon 51) were diagnosed with tumors. They were diagnosed with DMD for delayed motor development in the Department of Neurology of Children′s Hospital Affiliated to Zhengzhou University. They presented with painless masses in the waist. Postoperative pathological diagnosis: the pathology and immunohistochemistry of case 1 showed an alveolar rhabdomyosarcoma (ARMS) and both myogenin and myogenic differentiation 1 positive; the pathology and immunohistochemistry of case 2 showed an alveolar soft part sarcoma(ASPS) and transcription factor enhancer 3 positive; both cases were myogenic tumors. Literature review (including this paper) showed that there were in total 14 cases with DMD combined with myogenic tumors including 13 cases of rhabdomyosarcoma (RMS) and 1 case of ASPS. All of them are male, and the age of onset of the tumors was 4-17 years. Pathological subtypes were described in 6 cases of ARMS and 5 cases of embryonal RMS, and were not described in 2 cases. The 9 cases described all had large deletions in the DMD gene which can change the reading frame of the DMD gene, and all gene mutations did not exceed exon 62. Conclusions:DMD gene with deletion may increase the risk of having myogenic tumors, and RMS is more common, which is manifested as painless mass in early stage. All DMD gene deletions do not exceed exon 62 and lead to change of the gene reading frame with severe clinical phenotype and degenerative changes in muscle function.

Coronary perforation is when a contrast agent or blood flows outside a blood vessel through a tear in a coronary artery.In this case,we reported a case of percutaneous coronary intervention for coronary calcified lesions,which led to iatrogenic coronary perforation and cardiac tamponade after the use of Shockwave balloon to treat intracoronary calcified nodules,and the management of PCI-related CAP was systematically reviewed through the literature.

Hashimoto's thyroiditis(HT)is a common endocrine disease,which can be classified into the category of goiter disease in traditional Chinese medicine.Professor LIU Min believes that the pathogenesis of HT is closely related to the heart and gallbladder,and its pathogenesis is due to the gallbladder constraint failing to descend and the disturbance of pivot,together with insufficient heart-qi and the disharmony between the nutritive qi and the defensive qi.For the treatment of HT,the modified Chaihu Guizhi Decoction is often used,which is mainly composed of Bupleuri Radix,Cinnamomi Ramulus,Scutellariae Radix,Pinelliae Rhizoma Praeparatum,Ginseng Radix et Rhizoma Rubra,Glycyrrhizae Radix et Rhizoma Praeparata cum Melle,Jujubae Fructus,Paeoniae Radix Alba,Os Draconis,Ostreae Concha,and Zingiberis Rhizoma Recens.Chaihu Guizhi Decoction has the actions of soothing gallbladder and relieving depression,restoring the function of shaoyang pivot,regulating nutritive qi and the defensive qi,and benefiting heart spirit,which exactly accords with the HT's pathogenesis of gallbladder constraint failing to descend and insufficient heart-qi.In the clinical treatment of HT,the modification of the drugs should be performed according to the concurrent syndromes of the patients,and the dosage of the drugs should also be adjusted.In addition to drug treatment,the attention should also be addressed to the adjustment of patients'lifestyle and dietary habits and to the emotional counseling,thus to achieve significant effect.

Objective To find potential biomarkers and analyzing metabolic pathways of the treatment by honey-processed Hedysari Radix,the cecal contents of rats with spleen-Qi deficiency were used as samples for analysis.Methods Sixty male SD rats were randomly divided into blank,model,experimental and control groups.The rats in other groups except the control group were carried out by using the three-factor compound modeling method of bitter-cold diarrhea,excessive exertion and hunger and satiety disorders.Experimental group was given 12.60 g·kg-1 honey-processed Hedysari Radix;control group was given 0.63 g·kg-1 lactobacillus bifidum triplex tabletsa;control and model groups received with equal volume of distilled water for a total of 15 days.Measure body weight,anal temperature,immune organ index of rats.Ultra-pressure liquid chromatography-quadrupole-exactive-mass spectrometry technology was used to measure the levels of endogenous metabolites in cecum contents.Orthogonal partial least squares discriminant analysis and database"Kyoto Encyclopedia of Genes and Genomes"were used to identify potential differential metabolites and possible metabolic pathways.Results After the intervention,the average body weight of the experimental,control,model and blank groups was(216.87±7.85),(210.96±9.03),(159.47±5.18)and(293.51±22.98)g;anal temperature was(36.14±0.48),(35.40±0.64),(34.50±0.78)and(36.61±0.34)℃;the thymus indexes were(1.19±0.20),(1.24±0.25),(0.47±0.15)and(1.31±0.21)mg·g-1;the spleen indexes were(1.95±0.33),(2.18±0.28),(1.61±0.27)and(2.29±0.24)mg·g-1.Compared with the model group,the above indexes of the experimental group and the control group were significantly increased(all P＜0.01).A total of 14 potential biomarkers of Honey-processed Hedysari Radix in treating spleen-Qi deficiency syndrome were screened out in this study,which mainly involved amino acid metabolism such as tryptophan and glutamate,riboflavin metabolism and adenosine 5'-monophosphate-activated protein kinase metabolism.Conclusion Honey-processed Hedysari Radix can further protect the intestinal mucosal barrier and reduce the intestinal inflammatory response by improving the metabolic level of cecum contents in rats with spleen-Qi deficiency in cecum contents,thus exerting the effect of strengthening the spleen and tonifying the Qi.
