This paper summarizes Professor SHI Zaixiang's clinical experience in treating high fever caused by sepsis using Chaihu Guizhi Ganjiang Decoction （柴胡桂枝干姜汤）. He holds that the key pathogenesis of sepsis involves constrained heat in the shaoyang and internal accumulation of water and fluids. The clinical manifestations such as high fever， chills， and alternating sensations of cold and heat are attributed to pathogenic heat constrained in the shaoyang. Meanwhile， soft tissue edema and serous cavity effusions are due to shaoyang dysfunction and internal water retention. In clinical practice， treating sepsis-related high fever requires addressing both the shaoyang-constrained heat and the associated edema and effusions. The therapeutic approach focuses on harmonizing the shaoyang and resolving internal fluids， using Chaihu Guizhi Ganjiang Decoction as the base formula with flexible modifications. Professor SHI emphasizes that this formula shows a rapid antipyretic effect， particularly in cases where multiple anti-infective treatments have failed.

LC3-associated phagocytosis (LAP) is a special phagocytosis occurring at the intersection of the two pathways of phagocytosis and autophagy. A hallmark event of the LAP process is the recruitment of microtubule-associated proteinⅠlight chain type 3-Ⅱ(LC3Ⅱ) to the phagosome surface of the monolayer membrane structure. The LAP pathway relies on the functions of the RUN domain and cysteine-rich domain containing, Beclin 1-interacting protein (Rubicon) and reduced nicotinamide adenine dinucleotide phosphate (NADPH) oxidase. The LC3-associated phagosome (LAPosome) binds to the lysosome to digest and degrade the contents. In recent years, increasing studies have found that LAP plays an important role in the infections caused by pathogenic microorganisms including fungi and bacteria. LAP is a crucial way in the host to resist and degrade the infection of pathogenic microorganisms. However, some pathogenic microorganisms can effectively escape from LAP in the host and even use LAPosome as a place for colonization and replication. This article summarized the recent progress in the role of LAP in host defense against pathogenic microorganism infection and the significance of it in the occurrence and development of diseases.

Objective: To compare the postoperative efficacy of simple double-row suture bridge technique and double-row suture bridge technique combined with type Ⅱ "Chinese way" in treating huge massive rotator cuff injury. Methods: The clinical data of 74 patients with unilateral massive rotator cuff injury admitted to Department of Orthopedic, Beijing Chaoyang Hospital, Capital Medical University, from January 2019 to September 2021 were retrospectively analyzed. There were 39 males and 35 females, aged (60.2±7.8) years (range: 42 to 77 years). During operation, 44 patients were treated with single double-row suture bridge technique (the simple group), and 30 patients were treated with double-row suture bridge technique combined with type Ⅱ "Chinese way" treatment (the combined group). In the simple group, only internal and external row anchors were used to fix the fractured rotator cuff, while in the combined group, the biceps long head tendon was first transposed to the footprint area and fixed with an internal row anchor tail thread, and then the remaining rotator cuff fracture was repaired with double-row suture bridge technique. The operation conditions were recorded. The range of motion of shoulder joint, visual analogue scale (VAS), American Society for Shoulder and Elbow Surgeons (ASES) score, University of California, Los Angeles (UCLA) score, Constant-Murley shoulder joint score before operation, 6 months after operation and at the last follow-up were compared between the two groups. Postoperative complications and imaging results were recorded. The difference values of each observation index before and after operation were calculated. The repeated measures analysis of variance was used for repeated measurement data, and LSD multiple comparison method was used for the data at different time points in the two groups. Results: All the patients successfully completed the operation, and no serious complications occurred during or after operation. The patients were followed up for (14.6±5.4) months (range: 6 to 24 months). In all patients, the shoulder range of motion, VAS, ASES score, UCLA score and Constant-Murley shoulder score at 6 months after operation and at the last follow-up were significantly improved compared with those before operation (all P<0.01), and the results at the last follow-up were also better than those at 6 months after operation (all P<0.01). The results of the combined group at 6 months after operation and at the last follow-up (all P<0.01) were better than those of the single group. At 6 months after operation and at the last follow-up, the anteroposternal X-ray showed no significant progress in the degeneration of shoulder joint. Of the 27 patients who completed MRI during follow-up, 14 patients re-injured of reconstructed rotator cuff tissue (type Ⅳ and type Ⅴ) was found in 14 cases, the incidence was 22.7% (10/44) in the simple group and 13.3%(4/30) in the combined group. There was no significant difference between the two groups(χ²=1.026, P=0.311). Conclusion: Compared with the simple double-row suture bridge technique, the method of double-row suture bridge technique combined with type Ⅱ "Chinese way" for repairing massive rotator cuff injury has better effect on improving the short-term pain symptoms, joint range of motion, restoring joint function, and has lower incidence of complications.

OBJECTIVE: Preliminary assessment of rabies virus neutralizing activity, safety and immunogenicity of a recombinant human rabies antibody (NM57) compared with human rabies immunoglobulin (HRIG) in Chinese healthy adults. METHODS: Subjects were randomly (1:1:1) allocated to Groups A (20 IU/kg NM57), B (40 IU/kg NM57), or C (20 IU/kg HRIG). One injection was given on the day of enrollment. Blood samples were collected on days -7 to 0 (pre-injection), 3, 7, 14, 28, and 42. Adverse events (AEs) and serious AEs (SAEs) were recorded over a period of 42 days after injection. RESULTS: All 60 subjects developed detectable rabies virus neutralizing antibodies (RVNAs) (> 0.05 IU/mL) on days 3, 7, 14, 28, and 42. The RVNA levels peaked on day 3 in all three groups, with a geometric mean concentration (GMC) of 0.2139 IU/mL in Group A, 0.3660 IU/mL in Group B, and 0.1994 IU/mL in Group C. At each follow-up point, the GMC in Group B was significantly higher than that in Groups A and C. The areas under the antibody concentration curve over 0-14 days and 0-42 days in Group B were significantly larger than those in Groups A and C. Fifteen AEs were reported. Except for one grade 2 myalgia in Group C, the other 14 were all grade 1. No SAEs were observed. CONCLUSION The rabies virus neutralizing activity of 40 IU/kg NM57 was superior to that of 20 IU/kg NM57 and 20 IU/kg HRIG, and the rabies virus neutralizing activity of 20 IU/kg NM57 and 20 IU/kg HRIG were similar. Safety was comparable between NM57 and HRIG.

Objective To investigate the role of tolerogenic dendritic cell (tolDC) in inducing immune tolerance in liver transplantation. Methods Liver transplantation rat models of spontaneous tolerance [Brown Norway (BN)→Lewis, tolerance group, n=6] and acute rejection (AR) (Lewis→BN) were established. In AR rat models, tolDC transfusion was performed in the study group (tolDC group, n=6) and no intervention was given in the control group (AR group, n=6). The survival time of rats in each group was observed. The transplant liver tissues of rats were prepared for pathological examination in each group. The expression of myeloid dendritic cell (mDC) and plasmacytoid dendritic cell (pDC) in rat peripheral blood, transplant liver, spleen and lymph nodes in each group was detected by flow cytometry. The expression levels of serum interleukin (IL)-10 and interferon (IFN)-γ in each group were measured by enzyme-linked immune absorbent assay. Results Pathological manifestations of rats in the AR group mainly included inflammatory cell infiltration and tissue structural disorder in transplant liver, and the survival time was 7-14 d. In the tolDC and tolerance groups, the transplant liver tissues were almost normal, and the longest survival time exceeded 100 d. Compared with the AR group, the expression levels of CD11⁺mDC in peripheral blood, transplant liver, spleen and lymph nodes of rats were significantly down-regulated in the tolerance and tolDC groups (all P < 0.05), and those of CD86 and major histocompatibility complex (MHC)Ⅱon the surface of CD11⁺mDC were also significantly down-regulated (all P < 0.05). Compared with the AR group, the expression levels of pDC in peripheral blood, transplant liver, spleen and lymph nodes of rats were significantly up-regulated in the tolerance and tolDC groups (all P < 0.05), whereas those of MHCⅡon the surface of pDC were all significantly down-regulated (all P < 0.05). Compared with the AR group, the expression levels of serum IL-10 were significantly up-regulated, and IFN-γ were significantly down-regulated in the tolerance and tolDC groups (all P < 0.05). Conclusions As tolDC subsets, mDC and pDC play a positive role in regulating the incidence of graft immune tolerance in rats after liver transplantation.

Objective: To analyze the clinical features of patients with odontogenic sinusitis (OS) treated by endoscopic sinus surgery (ESS). Methods: A retrospective investigation was carried out in our 27 (16 males and 11 females) cases with OS aged (49.74±14.42) years old. Subjects were hospitalized between January 2018 and November 2020 from Department of Otorhinolaryngology Head and Neck Surgery, Beijing Chaoyang Hospital. The medical history, symptoms, result of nasal endoscopy and paranasal sinus computed tomography (CT) were analyzed statistically by SPSS 19.0. Results: OS mainly occured on unilateral sinuses, with a duration of (8.56±11.79) months. Seventy point four percent (19/27) of the patients had a course within six-month, only 11% was over 12 months (3/27). Symptoms mostly showed as nasal obstruction (88.9%; 24/27), runny nose (81.5%; 22/27), nasal stinks (16/19) and postnasal drip (10/10). Sixty-three percent (17/27) of the OS patients had a dental history. Nasal endoscopic examination revealed a swelling of the ostiomeatal complex (77.8%; 21/27), medial wall interhal displacement of maxillary sinus (55.6%; 15/27), white emulsion-like purulent secretion in the middle meatus (70.4%; 19/27) and nasal polyps (59.3%; 16/27). Etiology of OS included implant-related problems (14.8%; 4/27) and periodontal disease (85.2%; 23/27). Conclusions: OS is usually unilateral sinusitis with a short history. Its clinical features show nasal stinks, white emulsion-like purulent secretion in the middle meatus and imaging findings of unilateral maxillary sinusitis with tooth-related lesions.

Objective To screen and identify the hub genes closely related to cardiac hypertrophy by using bioinformaticsmethod and biological experiments. Methods The chip data related to cardiac hypertrophy in mice were downloaded from the Gene Expression Omnibus (GEO) database, and the GE02R online tool was adopted to screen for differentially expressed genes; DAVID 6.7, String 11.0 and Cytoscape 3.7. 0 softwares were used to analyze differentially expressed genes; Kunming mice were randomly divided into a normal saline group (n = 6) and an angiotensin II (Ang II) group (n = 6) to establish a cardiac hypertrophy model, the expression of hub gene in Kunming mouse model of cardiac hypertrophy induced by Ang II was detected by Real-time PCR method. Results A total of 202 common differentially expressed genes and 12 hub genes were selected; the Real-time PCR result demonstrated that decorin(Dcn), HADHA and heat shock protein (HSP) 90αA 1 were significantly down-regulated in the Angli group. Conclusion The selected hub genes can influence the development of cardiac hypertrophy in Kunming mice through extracellular matrix and transforming growth factor β(TGF-β).

Aging is the process spontaneously occurred in living organisms. Cardiac fibrosis is a pathophysiological process of cardiac aging. Mangiferin is a wellknown C-glucoside xanthone in mango leaves with lots of beneficial properties. In this study, rat model of cardiac fibrosis was induced by injected with 150 mg/kg/d Dgalactose for 8 weeks. The age-related cardiac decline was estimated by detecting the relative weight of heart, the serum levels of cardiac injury indicators and the expression of hypertrophic biomakers. Cardiac oxidative stress and local inflammation were measured by detecting the levels of malondialdehyde, enzymatic antioxidant status and proinflammatory cytokines. Cardiac fibrosis was evaluated by observing collagen deposition via masson and sirius red staining, as well as by examining the expression of extracellular matrix proteins via Western blot analysis. The cardiac activity of profibrotic TGF-β1/p38/MK2 signaling pathway was assessed by measuring the expression of TGF-β1 and the phosphorylation levels of p38 and MK2. It was observed that mangiferin ameliorated D-galactose-induced cardiac aging, attenuated cardiac oxidative stress, inflammation and fibrosis, as well as inhibited the activation of TGF-β1/p38/MK2 signaling pathway. These results showed that mangiferin could ameliorate cardiac fibrosis in D-galactose-induced aging rats possibly via inhibiting TGF-β/p38/MK2 signaling pathway.
