Mongolian medicine external treatment,which called five kinds of treatment in ancient time,is a kind of exter-nal treatment including fire moxibustion,poultice,soaking and other therapies.The therapy was gradually developed and per-fected in the course of Mongolian people's long-term struggle against diseases,which has characteristics of small trauma and suitable for long-term application.In this paper,the research progress of external treatment of orthopedic diseases in Mongolian medicine in recent years was summarized,and it was concluded that external treatment of orthopedic diseases in Mongolian medicine had distinct characteristics and accurate efficacy.However,there are still deficiencies in the standardization of clini-cal operation and the study of the mechanism of therapeutic action,which need further research and improvement.

Bacterial biofilms gave rise to persistent infections and multi-organ failure, thereby posing a serious threat to human health. Biofilms were formed by cross-linking of hydrophobic extracellular polymeric substances (EPS), such as proteins, polysaccharides, and eDNA, which were synthesized by bacteria themselves after adhesion and colonization on biological surfaces. They had the characteristics of dense structure, high adhesiveness and low drug permeability, and had been found in many human organs or tissues, such as the brain, heart, liver, spleen, lungs, kidneys, gastrointestinal tract, and skeleton. By releasing pro-inflammatory bacterial metabolites including endotoxins, exotoxins and interleukin, biofilms stimulated the body’s immune system to secrete inflammatory factors. These factors triggered local inflammation and chronic infections. Those were the key reason for the failure of traditional clinical drug therapy for infectious diseases.In order to cope with the increasingly severe drug-resistant infections, it was urgent to develop new therapeutic strategies for bacterial-biofilm eradication and anti-bacterial infections. Based on the nanoscale structure and biocompatible activity, nanobiomaterials had the advantages of specific targeting, intelligent delivery, high drug loading and low toxicity, which could realize efficient intervention and precise treatment of drug-resistant bacterial biofilms. This paper highlighted multiple strategies of biofilms eradication based on nanobiomaterials. For example, nanobiomaterials combined with EPS degrading enzymes could be used for targeted hydrolysis of bacterial biofilms, and effectively increased the drug enrichment within biofilms. By loading quorum sensing inhibitors, nanotechnology was also an effective strategy for eradicating bacterial biofilms and recovering the infectious symptoms. Nanobiomaterials could intervene the bacterial metabolism and break the bacterial survival homeostasis by blocking the uptake of nutrients. Moreover, energy-driven micro-nano robotics had shown excellent performance in active delivery and biofilm eradication. Micro-nano robots could penetrate physiological barriers by exogenous or endogenous driving modes such as by biological or chemical methods, ultrasound, and magnetic field, and deliver drugs to the infection sites accurately. Achieving this using conventional drugs was difficult. Overall, the paper described the biological properties and drug-resistant molecular mechanisms of bacterial biofilms, and highlighted therapeutic strategies from different perspectives by nanobiomaterials, such as dispersing bacterial mature biofilms, blocking quorum sensing, inhibiting bacterial metabolism, and energy driving penetration. In addition, we presented the key challenges still faced by nanobiomaterials in combating bacterial biofilm infections. Firstly, the dense structure of EPS caused biofilms spatial heterogeneity and metabolic heterogeneity, which created exacting requirements for the design, construction and preparation process of nanobiomaterials. Secondly, biofilm disruption carried the risk of spread and infection the pathogenic bacteria, which might lead to other infections. Finally, we emphasized the role of nanobiomaterials in the development trends and translational prospects in biofilm treatment.

Objective: To investigate the possible pathophysiological mechanism of laryngopharyngeal reflux (LPR) in the development of lingual tonsil hypertrophy (LTH). Methods: The lingual tonsil tissues were collected from 73 patients [48 males and 25 females, aged from 24 to 76 (52.86±12.04) years] who underwent surgery for laryngopharyngeal diseases at the Department of Otolaryngology and Head and Neck Surgery, Southern Hospital of Southern Medical University from October 2019 to December 2020, and the lingual tonsil grade (LTG), reflux symptom index (RSI) and reflux finding score (RFS) were assessed. The expression of pepsin in LTH was detected by immunohistochemistry. The coexpression of pepsin and macrophages were detected by immunohistofluorescence. In vitro, cytological experiments and pathway assays were performed on macrophages stimulated by pepsin. Pathway alterations of macrophages in pepsin-positive high-grade LTH were detected by double-fluorescence immunohistochemistry. Data were analyzed by SPSS 20.0 software. Results: There were 44 clinically significant LPRD patients with LTG 3 and 4, and the pepsin positive rate was 88.6% (39/44). While, the pepsin positive rate of LTG 1 and 2 was 48.3% (14/29). LTG was significantly positively correlated with RFS/RSI positive rate(χ²=23.01/19.62, P<0.001/0.001; r=0.54/0.51, P<0.001/0.001) and pepsin tissue staining intensity (H=21.58, P<0.001; r=0.53, P<0.001), respectively. Pepsin and macrophages were clearly colocalized in high grade LTH. In vitro, pepsin promoted macrophage proliferation (P<0.05) and production of IL-6/IL-8 (P<0.05). Pepsin significantly up-regulated the p38/JNK MAPK pathway in macrophages (P<0.05). Pepsin up-regulated the expression of IL-6 and IL-8 of macrophages by activating the p38 MAPK pathway (P<0.05), and up-regulated the expression of IL-8 by activating the JNK pathway (P<0.05). The p38/JNK MAPK pathways were highly expressed in macrophages of pepsin-positive LTH (P<0.05). Conclusions: LPR is an important pathogenic factor in LTH. Macrophages may mediate pepsin-induced inflammation and the pathogenesis of LTH.

Neural precursor cell Expressed‚Developmentally Down-regulated protein 4 (NEDD4-1‚ also known as NEDD4 in some papers) is a tumor-related protein that has attracted much attention in recent years. It belongs to the E3 HECT (homologous to E6 associated protein C terminus) ubiquitin ligase‚ which could ubiquitinate various proteins that are subsequently degraded in lysosomes or proteasomes‚ or mediate their nuclear-cytoplasmic translocation‚ or indirectly affect various signaling pathways of different malignant tumors. With the deepening of a large number of tumor-related experiments‚ it has been found that NEDD4-1 can affect the biological behavior of tumors by regulating cell cycle‚ invasion and metastasis of cancer cells‚ antagonize drug resistance and many other pathways. In digestive system tumors‚ NEDD4-1 mainly promotes the proliferation‚ invasion and migration of hepatocellular carcinoma through multiple pathways such as PTEN/ PI3K/ Akt‚ TGF-β‚ Hippo and LDLRAD4. In pancreatic cancer‚ NEDD4-1 acted as an oncogene in the PI3K/ Akt signaling pathway‚ but acted as a tumor suppressor gene in the Myc-Sirt2 signaling circuit. In gastric and colorectal cancer‚ the NEDD4-1-related signaling pathways are different from other digestive system tumors. NEDD4-1 promotes gastric cancer progression and metastasis (via the EGFR signaling pathway) and inhibits colorectal cancer tumor growth (via the Wnt signaling pathway) independently of the PTEN/ PI3K/ Akt pathway. NEDD4-1 has become a hot research direction for therapeutic purposes. In this paper‚ we summarize the functions‚ signaling pathways and potential inhibitors of NEDD4-1 in different digestive system tumors‚ and discuss the relationship between NEDD4-1 and different signaling pathways‚ aiming to provide important reference data for cancer therapy.

TGFβ/smad pathway is recognized as an important signal pathway to promote the pathogenesis of atherosclerosis (AS). Peroxisome proliferator-activated receptor γ (PPARγ) activation is considered to be important in modulating AS. Herein, we investigated the regulation of PPARγ on c-Ski, the repressor of TGFβ/smad pathway, in rat AS model and cultured vascular smooth muscle cells (VSMCs). c-Ski mRNA and protein expression were detected by real-time PCR and Western blot, respectively, in vivo and in vitro with treatment of PPARγ agonist rosiglitazone and antagonist GW9662. The proliferation and collagen secretion of VSMCs after c-Ski transfection were investigated. The underlying mechanism was further investigated by online program NUBIScan and luciferase reporter gene analysis. Results showed that both mRNA and protein expressions of c-Ski in the AS lesions was down-regulated in vivo, while in cultured VSMCs, c-Ski transfection significantly suppressed the proliferation and collagen secretion of rat VSMCs. Rosiglitazone significantly up-regulated mRNA and protein levels of c-Ski in VSMCs, which could be blocked by GW9662. Online NUBIScan analysis suggested possible PPARγ binding sites in the promoter region of c-Ski. In addition, luciferase activity of c-Ski reporter gene was also increased obviously in the presence of rosiglitazone. These results indicate that c-Ski is one of the newly found target genes of PPARγ and thus involved in the anti-AS effect of PPARγ.

Objective To study the prevalence and risk factors for personality disorder (PD)outpatients attending in for psychiatric and psychological counseling in Shanghai. Methods 3075 subjects were sampled by systematic sampling method from outpatients in psycho-counseling clinics and psychiatric clinics in Shanghai Mental Health Center. Based on DSM- Ⅳ criteria, personality disorders were assessed by both questionnaires (personality diagnostic questionnaire, PDQ-4+) and interviews (structured clinical interview for DSM- Ⅳ Axis Ⅱ , SCID- Ⅱ ). Logistic regression analysis was performed to determine the significant independent contributor to PD. Results 71.3% of the outpatients were found having pathological personality by using questionnaire of self rating PD scale. 982 outpatients (31.9%) met criteria for at least one personality disorder by using structured clinical interview. Younger age (OR= 1.8, 95% CI: 1.5-2.1 ), single or divorced (OR = 1.6, 95%CI:1.4-1.9), psychological counseling outpatients (OR=1.2, 95%CI: 1.1-1.3), mood and outpatients with neurosis disorders (OR = 1.7, 95%CI: 1.4-2.0) were more frequently assigned as personality disorders. Data from logistic regression analysis showed that patients of tender age, not nurtured and raised by their parents, with introvert characters were related risk factors of PD. Conclusion High prevalence rate of PD was found in this sample of Chinese outpatients, especially in thosepsychological counseling outpatients with mood or neurosis disorders. More attention should be paid to the recognition and intervention of PD in outpatients with mental disorders.
