Based on the etiology and clinical diagnostic criteria of type 2 diabetes mellitus （T2DM）， identification and typing of treatment from the perspective of traditional Chinese and western medicine， the criteria for evaluating the clinical compatibility of traditional Chinese and western medicine in animal models of T2DM were set up. The literature was reviewed to sort out and analyze the existing commonly used modeling methods， summarize the mechanism， compare the advantages and disadvantages， and calculate the consistency between the animal model and the clinical symptoms， syndromes， and indicators from the perspective of traditional Chinese and western medicine. The authors found that spontaneous animal models and high-fat diets combined with multiple low-dose streptozotocin （STZ） induction models were more in line with modern medical pathogenesis of T2DM. However， it fails to form some special syndromes required for traditional Chinese medicine （TCM） research. In addition， there are many methods of combining the etiology and pathogenesis of TCM， which can be divided into three categories： intervention carried out by drug administration， behavioral stimulation， or environmental changes according to TCM， or use of hormones according to clinical evidence and combination of the two methods mentioned above. All of them can successfully establish different types of animal models. However， different methods of establishing syndrome models have their own advantages and disadvantages， and there is no unified standard for the stability and evaluation of syndrome models. As for the clinical consistency criteria of traditional Chinese and western medicine established in this paper， the animal model with 100% consistency has not been calculated due to the conditions of incomplete symptoms and syndromes described in the studies and different selection indicators. Consequently， the establishment of a simple， easy-to-use， and affordable T2DM animal model with both traditional Chinese and western medicine disease characteristics and the improvement of the Chinese and western medicine evaluation system for different evidence types are of great significance for the future development of TCM research on T2DM.

Tuberculosis is a zoonotic disease posing a substantial public health threat.Immunological diagnosis and vaccine im-munization are both necessary to control tuberculosis prevalence.However,the identical antigenic components in diagnostic reagents and vaccines hinder the use of animal vaccines and limit the specificity of clinical diagnosis in humans.Differentiating infected from vaccinated animals can overcome these problems.This article reviews the progress in differential diagnosis research from three as-pects:the diagnostic effects of antigens,methods for discovering new antigens,and screening of new host immune markers,to provide a theoretical basis for future research.

Two male patients with bifid rib-basal cell nevus-jaw cyst syndrome (BCNS) were admitted to Department of Stomatology, the First Affiliated Hospital of Bengbu Medical College due to radiological findings of multiple low density shadows in the jaw. Clinical and imaging findings showed thoracic malformation, calcification of the tentorium cerebellum and falx cerebrum as well as widening of the orbital distance. Whole exon high-throughput sequencing was performed in two patients and their family members. The heterozygous mutations of c.C2541C>A(p.Y847X) and c.C1501C>T(p.Q501X) in PTCH1 gene were detected in both patients. Diagnosis of BCNS was confirmed. The heterozygous mutations of PTCH1 gene locus were also found in the mothers of the two probands. Proband 1 showed clinical manifestations of low intelligence, and heterozygous mutations of c.C2141T(p.P714L) and c.G3343A(p.V1115I) were detected in FANCD2 gene. Proband 2 had normal intelligence and no FANCD2 mutation. The fenestration decompression and curettage of jaw cyst were performed in both patients. Regular follow-up showed good bone growth at the original lesion, and no recurrence has been observed so far.

Chronic inflammation induced by Helicobacter pylori is considered to be one of the main causes of gastric cancer,and CagA is a main virulence factor of H.pylori.The study aimed to investigate the role and mechanism of CagA in host inflammatory response.Mass spectrometry was used to identify the interacting proteins of CagA in AGS cells.By immunoprecipitation and immunofluorescence,the interaction was validated.Pathway expression was detected by immunoblotting after knockdown by using siRNA,and mRNA levels of inflammatory cytokines were detected by quantitative PCR.CagA-induced inflammatory responses were detected in clinical samples using hemoglobin-eosin staining(H&E).Data showed that CagA interacted with SHARPIN.And CagA activated the NF-κB signaling pathway and upregulated the mRNA and protein levels of the inflammatory cytokines IL-6,IL-8,and TNF-α,as compared with the CagA knockout strain(all P<0.05).Knockdown of SHARPIN by siRNA reduced inflammation levels and partially inhibit NF-κB signaling.In clinical samples,CagA-positive samples exhibited stronger inflammatory responses.To sum up,CagA promoted the host inflammatory response,and CagA-induced inflammatory response was reduced when SHARPIN was partially inhibited,suggesting that CagA activates the NF-κB signaling pathway through binding to SHARPIN.

Objective:To investigate the radiosensitizing effect and underlying mechanism of STING agonist (c-di-AMP) on cutaneous melanoma cells.Methods:Human cutaneous melanoma cells (A375) were divided into four groups: the control group, 10 μmol/L c-di-AMP group, X-ray irradiation group and X-ray irradiation combined with c-di-AMP group. The radiosensitizing effect of c-di-AMP on A375 cells was detected by CCK-8-based viability assay, lactate dehydrogenase (LDH) release assay, flow cytometry-based apoptosis assay, and colony formation assay. Western blot analysis was used to determine the expressions of cell death-related proteins.Results:In combination with 10 Gy X-ray irradiation, 10 μmol/L c-di-AMP showed significant radiosensitization effect in A375 cells, which was evidenced by decreased cell activity ( t=5.11, P<0.05), increased cytotoxicity ( t=10.15, P<0.05) and cell apoptosis ( t=4.41, P<0.05) and reduced clone viability( t=6.30, 3.55, 5.45, 3.55, P<0.05). The calculated radiosensitization ratio of c-di-AMP to A375 cells was 1.88. Moreover, 10 μmol/L c-di-AMP further increased the expressions of cell death-related proteins induced by radiation in A375 cells. Conclusions:The STING agonist c-di-AMP can be used as a radiosensitizer for cutaneous melanoma, which may provide a novel strategy for radiotherapy.

Objective:To investigate the clinical effect of thin superficial inferior epigastric artery flaps in repairing soft tissue defects after buccal cancer surgery.Methods:From January 2018 to October 2019, 6 patients with buccal cancer who underwent surgery were constructed with thin superficial inferior epigastric artery flaps, including 2 males and 4 females, aged 43 to 68 years, with an average of 61.5 years. Doppler ultrasound was utilized of all patients to design flap preoperatively . According to the size of the affected area defect, according to the shape and direction of the blood vessels, a thin superficial inferior epigastric artery flap was elevated above the Scarpas fascia layer and transferred to repair soft tissue defects after buccal cancer surgery. The survival and functional recovery of the flap were observed.Results:All 6 flaps survived. The superficial inferior epigastric artery flaps ranged from 5.0 cm×7.0 cm to 7.0 cm×9.0 cm. The thickness of the flaps ranged from 0.5 cm to 1.3 cm, and the average thickness was 0.8 cm. The pedicle length is 6.0-9.0 cm.Four of them anastomosed to the superficial inferior epigastric veins and companion vein, 2 cases only anastomized superficial inferior epigastric veins . The follow-up period ranged from 3 to 12 months, with an average of 10 months. The cheek shape was good, the mouth opening was normal, there was no obvious bloating, and no secondary surgery was required. Linear scars were left on the donor site, with concealed location and no impairment of abdominal wall function.Conclusions:The donor site of the thin superficial inferior epigastric artery flap is small, the scar is concealed, the cheek is not bloated, and the opening degree of mouth is satisfactory. It is a good choice for reconstructing postoperative defect of cheek cancer.
