Kidney deficiency syndrome is a common clinical syndrome in traditional Chinese medicine （TCM）. With the progress of science and technology， clinical and animal experiments on kidney deficiency syndrome have made remarkable progress. Research on kidney deficiency and the nature of "kidney" involves a large number of physiological and pathological bases， which are closely related to physiological and pathological links in the human body， among which the neuroendocrine-immune network shares the closest relationship. However， there are still many challenges in modern research on kidney deficiency syndrome， such as expert consensus on clinical diagnostic criteria and evaluation indexes and optimization of animal experimental models. In the past decade， a large number of clinical and animal experiments have been reported in the literature on kidney deficiency syndrome， among which the literature focusing on the combination of disease and syndrome is predominant， and most of them focus on kidney Yang deficiency and kidney Yin deficiency， involving the exploration of many pathological mechanisms. Research on the mechanisms related to kidney deficiency syndrome encompasses multiple signaling pathways and various biochemical indicators， including the phosphatidylinositol 3-kinase/protein kinase B/nuclear factor-erythroid 2-relatedfactor-2（PI3K/Akt/Nrf2） signaling pathway， the Toll-like receptor 4/myeloid differentiation factor88/nuclear factor-κB（TLR4/MyD88/NF-κB） signaling pathway， the Janus kinase 2/signal transducer and activator of transcription 3（JAK2/STAT3） signaling pathway， Osteoprotectin/nuclear factor-κB receptor activator ligand/receptor activator of nuclear factor-κB （OPG/RANKL/RANK） signaling pathway. The biochemical indicators cover the cyclic adenosine monophosphate/cyclic guanosine monophosphate （cAMP/cGMP） ratio， Na⁺-K⁺-ATPase activity， Ca²⁺-Mg²⁺-ATPase activity， adrenocorticotropic hormone （ACTH）， polycorticosterone （CORT）， 17-OHCS， and other sex hormone indicators， providing crucial reference values for diagnosing kidney Yang deficiency or kidney Yin deficiency. The literature related to kidney deficiency syndrome over the past decade was collated and excavated， with a view to providing a reference for research on kidney deficiency syndrome.

Objective:To investigate the effects of intra-articular injection of exosomes derived from dental pulp stem cells from hu-man exfoliated deciduous teeth(SHED-EXO)on subchondral bone homeostasis in rat temporomandibular joint osteoarthritis(TMJ OA)process.Methods:36 male SD rats were randomly divided into 3 groups(n=12):control(CON),sodium iodoacetate(MIA)-induced TMJ OA(MIA),and SHED-EXO injection into TMJ OA(SHED-EXO)groups.At 2 and 6 weeks post-treatment,Micro-CT,Double labeling,TRAP staining,and immunohistochemical staining were employed to detect osteoclasts and osteoblasts in the subchondral bone.Additionally,the mRNA expression levels of ADAMTs5,IL-1β,OCN and OPG/RANKL were analyzed by qRT-PCR.Results:The MIA group exhibited significant bone loss and an enlarged bone marrow cavity.In comparison with the CON group,BV/TV and Tb.Th were lower(P＜0.001),while BS/BV,Tb.Sp,and Tb.N were higher(P＜0.01).Additionally,the bone formation rate within 5 days was low-er than that of the control group(P＜0.001).When compared to the MIA group,the SHED-EXO group showed a significant increase in bone morphology and bone mass.BV/TV and Tb.Th were increased(P＜0.01),while BS/BV,Tb.Sp and Tb.N were decreased(P＜0.05).The bone formation rate was higher(P＜0.01).Compared with both the control and treatment groups,the MIA group exhibited a significant increase in the number of osteoclasts in the subchondral bone(P＜0.01),along with a notable decrease in H-type blood vessels and OCN-positive areas(P＜0.01).Conclusion:Intra-articular injection of SHED-EXO can reg-ulate condylar subchondral bone homeostasis in TMJ OA of rats by promoting osteogenesis and inhibiting osteoclasts.

ObjectiveTo clarify the therapeutic effect of Huashi Baidu prescription on pneumonia in mice caused by influenza A （H1N1） virus and explore its mechanism based on the transcriptome. MethodA mouse influenza viral pneumonia model was built by intranasal infection with influenza A virus， and mice were continuously administered the drug for five days， so as to investigate the general condition， lung index， viral load， pathological morphology of lung tissue， survival time， and prolongation rate of survival time of mice and clarify the therapeutic effect of Huashi Baidu prescription on influenza viral pneumonia. Transcriptome technology was used to detect the differentially expressed genes in the lung tissue of mice in the model group and the normal group， as well as the Huashi Baidu prescription group and the model group， and the potential core target of the Huashi Baidu prescription for the treatment of influenza viral pneumonia was screened. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to verify the effect of Huashi Baidu prescription on the mRNA expression level of core target genes. ResultCompared with the normal group， the lung index and viral load in the lung tissue of the model group were significantly increased （P<0.05， P<0.01）. Compared with the model group， the high-dose group of Huashi Baidu prescription significantly prolonged the survival time of mice infected with influenza A virus （P<0.05） and significantly reduced the lung index value of mice （P<0.05） and the viral load of lung tissue. The high-dose， medium-dose， and low-dose groups of Huashi Baidu prescription could significantly reduce lung tissue inflammation， blood stasis， swelling， and other pathological changes in mice （P<0.05， P<0.01）. Transcriptome analysis of lung tissue showed that core genes were mainly enriched in the nuclear transcription factor-κB （NF-κB） signaling pathway， interleukin-17 （IL-17） signaling pathway， cytokine-cytokine receptor interaction， and other pathways after the intervention of Huashi Baidu prescription. TRAF6， NFKBIA， CCL2， CCL7， and CXCL2 were the top five node genes with combined score values. Real-time PCR validation showed that Huashi Baidu prescription significantly downregulated the mRNA expression of key genes TRAF6 and NFKBIA in the NF-κB signaling pathway， as well as chemokines CCL2， CCL7， and CXCL2 （P<0.05， P<0.01）. ConclusionHuashi Baidu prescription has a therapeutic effect on influenza viral pneumonia， possibly by inhibiting the expression of key nodes TRAF6 and NFKBIA in the NF-κB signaling pathway and that of chemokines CCL2， CCL7， and CXCL2， reducing the recruitment of inflammatory cells and viral load， and exerting anti-influenza viral pneumonia effects.

As a promising modality for cancer therapy, photodynamic therapy (PDT) still acquired limited success in clinical nowadays due to the extremely serious hypoxia and immunosuppression tumor microenvironment. To ameliorate such a situation, we rationally designed and prepared cascade two-stage re-oxygenation and immune re-sensitization BSA-MHI148@SRF nanoparticles via hydrophilic and hydrophobic self-assembly strategy by using near-infrared photodynamic dye MHI148 chemically modified bovine serum albumin (BSA-MHI148) and multi-kinase inhibitor Sorafenib (SRF) as a novel tumor oxygen and immune microenvironment regulation drug. Benefiting from the accumulation of SRF in tumors, BSA-MHI148@SRF nanoparticles dramatically enhanced the PDT efficacy by promoting cascade two-stage tumor re-oxygenation mechanisms: (i) SRF decreased tumor oxygen consumption via inhibiting mitochondria respiratory. (ii) SRF increased the oxygen supply via inducing tumor vessel normalization. Meanwhile, the immunosuppression micro-environment was also obviously reversed by two-stage immune re-sensitization as follows: (i) Enhanced immunogenic cell death (ICD) production amplified by BSA-MHI148@SRF induced reactive oxygen species (ROS) generation enhanced T cell infiltration and improve its tumor cell killing ability. (ii) BSA-MHI148@SRF amplified tumor vessel normalization by VEGF inhibition also obviously reversed the tumor immune-suppression microenvironment. Finally, the growth of solid tumors was significantly depressed by such well-designed BSA-MHI148@SRF nanoparticles, which could be potential for clinical cancer therapy.

Objective:To investigate the relationship between plasma levels of complements before treatment and the clinicopathological feathers and prognoses of diffuse large B-cell lymphoma (DLBCL) patients treated with Rituximab (R)-CHOP or R-CHOP-like therapy.Methods:The clinicopathological data of 105 DLBCL patients treated in cancer Hospital of Chinese Academy of Medical Sciences from 2010 to 2016 were collected. The plasma samples from 105 DLBCL patients treated with R-CHOP or R-CHOP-like therapy and 80 healthy controls were used to detect 34 complement levels before treatment by utilizing antibody microarray. The relationship between plasma levels of complements and the clinicopathological feathers and prognosis of DLBCL patients were analyzed.Results:The signal values of C1QA and CR1L in patients with international prognostic index (IPI) scores of 3-5 were 1 261.43±138.9 and 2 214.69±98.58, respectively, higher than 950.79±80.19 and 984.67±121.79 in patients with IPI scores of 0~2 (both P<0.05). The levels of C1QA and CR1L in the non-complete response (CR) group were 1 165.43±98.56 and 2 263.13±145.63, respectively, higher than 914.70±100.77 and 1 821.34±84.68 in the CR group (both P<0.05). Cox regression analysis showed that elevated C1QA signal value was associated with poor progression-free survival (PFS) and poor overall survival (OS) (PFS: HR=2.063, 95% CI: 1.220-3.489, P=0.007; OS: HR=2.23, 95% CI: 1.036~4.798, P=0.040). After IPI correction by Cox multivariate model, the elevated C1QA signal value was still correlated with poor PFS ( HR=1.765, 95% CI 1.034~3.013, P=0.037). Conclusions:The baseline plasma levels of C1QA and CR1L are correlated with IPI scores and therapeutic effects of DLBCL patients treated with R-CHOP. The baseline plasma level of C1QA has a certain predictive value for the prognostic evaluation of DLBCL.

Objective:To explore the application of formative assessment in clinical skills simulated training course.Method:s The clinical skills simulated training course for excellent doctors in our school was selected as the research focus, students of Grade 2014 adopted traditional summative evaluation (control group), and the multi-station examination was used as evaluation method. Students of Grade 2015 adopted the formative evaluation on the basis of summative evaluation (experimental group), a diversified evaluation system was established, including inter-group evaluation by students, random evaluation by teachers, feedback of operation videos of different stages and real-time feedback of students' opinions after class. Questionnaires were conducted among students and teachers at the end of the course.Result:s The scores of the experimental group were higher than those of the control group, with differences being statistically significant ( P<0.05). Questionnaires showed that the proportion of "good" selected by teachers and students in the feedback of formative assessment was markedly higher than that of "just so-so" and "bad", indicating that formative assessment is conducive to increasing students' initiative for self-studying, improving students' learning effect, comprehensively and accurately evaluating students' clinical operational skills, as well as improving the teaching level of clinical practice skills. Conclusion:The diversified evaluation system, which combines formative evaluation with summative evaluation, has achieved good teaching results in clinical skills simulated training course and it is worth to be widely applied.

Objective:To analyze the clinical course and targeted therapy of pyogenic sterile arthritis, pyoderma gangrenosum, and acne (PAPA) syndrome.Methods:The clinical history of a 6-year-old boy with PAPA syndrome, who was admitted to Hong Kong University Shenzhen Hospital in September 2017, was reviewed. His genetic diagnosis was confirmed by whole exome sequencing. The response to targeted therapy was evaluated by comparing the inflammatory markers (erythrocyte sedimentation rate (ESR) and C reactive protein (CRP) and serum cytokines (interleukin (IL)-1, IL-6 and tumor necrosis factor-α (TNF-α)) before and after biological agents treatment. For literature review, "PAPA syndrome" and"PSTPIP1 gene"were used as keywords to retrieve papers published from January 1997 to December 2019 from Pubmed, Wanfang and CNKI database.Results:The patient was a 6-year-old boy, admitted to the hospital due to recurrent joint swelling and pain for more than 4 years. Before treatment, the CRP (256 mg/L), ESR (105 mm/1 h) and cytokines including serum TNF-α (7.43 ng/L), IL-1 (<5 ng/L), IL-6 (301 ng/L) were significantly elevated. Culture of the joint effusion was negative, but the IL-6 level was above 1 000 ng/L. MRI showed osteomyelitis at the lower end of the right femur. Gene detection found a heterozygous variation of PSTPIP1 gene (c.748G>A, p.E250K). Arthralgia once alleviated after the initiation of tocilizumab and infliximab, but recurred after 1 year of treatment. Thereafter, the anti-IL-1 receptor antagonist (Anakinra) was commenced, followed by a significant improvement of the arthralgia, and a complete remission during the follow-up. Besides, the level of CRP, ESR, serum TNF-α, IL-1 and IL-6 were all decreased to normal on the last followed up in December 2019. Literature review found 29 articles and 87 patients in total. The initial symptoms included those of arthritis ( n=58), pyoderma gangrenosum ( n=33), and acne ( n=24). Among all the cases, 13 genotypes were confirmed, and 47 variations involved amino acid p.E250. Steroid and/or biological agents were used in most patients. Conclusions:PAPA syndrome should be suspected in children with recurrent pyogenic sterile arthritis, and an early diagnosis could be achieved by genetic test. Targeted treatment with biological agent may control the symptoms effectively. Biological agents can control symptoms of this disorder effectively.
