Professor Li Candong puts forward the"five differentiation"thinking in TCM:symptom differentiation,syndrome differentiation,disease differentiation,person differentiation and mechanism differentiation.This article discussed the thinking and method of application of classical prescriptions based on the mode of"five differentiation".Treatment based on symptom differentiation is a quick method of application of classic prescriptions,which includes searching for specific symptoms or symptom groups and according to special tongue images.Treatment based on syndrome differentiation is a commonly used method in classic prescriptions,distinguishing between primary and secondary syndromes and the authenticity of cold and heat.Treatment based on disease differentiation is the inherent meaning of classic prescriptions,which is mainly to distinguish six meridian diseases and special prescriptions for specific diseases.Treatment based on person differentiation embodies the individual differences in the use of classic prescriptions,which include age,gender,constitution and abdominal syndrome.Treatment based on mechanism differentiation is an ingenious method used by classic prescriptions.When practicing clinical medicine,we should adhere to the integrated mode of"five differentiation"in the application of classic prescriptions,comprehensively considering the five dimensions,in order to improve the accuracy and effectiveness of the application of classic prescriptions,reveal and improve the academic system of classic prescriptions,and better guide their clinical application.

Chronic fatigue syndrome(CFS)is a chronic comprehensive disease with a slow course and often accompanied by a variety of physical and psychiatric symptoms.At present,the incidence rate is on the rise.Based on the theory of"qi-pulse smooth and unobstructed",the pathogenesis of CFS is considered to be the loss of spleen and kidney and the deficiency of qi-pulse as the root;liver and lung disorders,qi-pulse stagnation as the pivot;wind fire invasion,phlegm blood stasis as the superficiality.Treatment should focus on tonifying the spleen and tonifying the kidneys to treat its root cause.According to the degree of deficiency of spleen and kidney and the emphasis of deficiency of qi-blood yin-yang,Buzhong Yiqi Decoction,Guipi Decoction,Shengyang Yiwei Decoction,Linggui Zhugan Decoction and Shenqi Pills should be selected flexibly.The methods of soothing the liver and regulating the lungs to regulate their pivot,harmonizing the liver and lungs,and using both ascending and descending functions should be used.Chaihu Shugan Powder,Xiaoyao Powder,Sini Powder,Guizhi Decoction,Shengmai Powder,etc.could be selected flexibly according to the disease location and disease focus.Clearing wind and clearing heat,eliminating phlegm and promoting blood circulation should be used to treat its superficiality,emphasizing tonifying deficiency and resolving depression.According to the different pathogenesis of patients,the corresponding treatment method should be flexibly chosen to supplement with medication.One medical case was attached in this article as the evidence,in order to provide reference for the TCM treatment of CFS.

Purpose To investigate the protective effect and mechanism of A-485 on renal tubular injury in diabetic mice.Methods Eighteen male C57BL/6J mice were randomly divided into three groups:Control group,diabetic kidney dis-ease(DKD)group and A-485 treatment group.The DKD mice model was established by feeding high-fat diet for 8 weeks and intraperitoneal injection of streptozotocin for 5 days.Subsequent-ly,the A-485 treatment group was given A-485(10 mg/kg/day)by intraperitoneal injection every other day for 4 weeks.After treatment,the renal function,P300 enzyme activity and lipid deposition in renal tissue were measured.Western blot a-nalysis was performed to detect SREBP-1,FASN,ACC,ChREBP,P300,CBP,H3K18ac and H3K27ac protein levels.Results Compared with control mice,the levels of FBG,BUN,Scr and UAE were significantly increased in diabetic mice(FBG:2.52 times,BUN:2.89 times,Scr:2.13 times,UAE:4.21 times),while diabetic mice treatment with A-485 exhibi-ted a remarkable decrease on BUN,Scr and UAE(BUN:0.511 times,Scr:0.636 times,UAE:0.574 times,P＜0.01).The results of the transmission electron microscopy and oil red O stai-ning showed that A-485 treatment prevents lipid droplets forma-tion and up-regulation of SREBP-1,FASN,ACC and ChREBP in renal tubular cells of diabetic mice(SREBP-1:0.544 times,FASN:0.449 times,ACC:0.306 times,ChREBP:0.317 times,P＜0.01).Furthermore,A-485 intervention downregu-lated the enzyme activity of P300(0.546 times)and suppressed the expression of H3K18ac(0.337 times)and H3K27ac(0.308 times,P＜0.01).Conclusion A-485 can significant-ly improve renal lipid metabolic disorder in diabetic mice,which may be achieved by inhibiting p300-induced H3K18ac and H3K27ac.

OBJECTIVE To study the pharmacokinetics of Esketamine hydrochloride nasal spray in rats and ciliary toxicity to maxillary mucosa of bullfrog. METHODS The plasma concentration of esketamine hydrochloride in rats was determined by LC-MS/ MS after intravenous injection of esketamine hydrochloride solution and nasal administration of esketamine hydrochloride； the pharmacokinetic parameters were calculated by using Phoenix WinNonlin 8.1.0 software. Using the maxillary mucosa of isolated bullfrog as a model， the morphological changes of maxillary mucosa were investigated， and the duration and recovery of ciliary oscillation were recorded after nasal administration of esketamine hydrochloride. RESULTS The peak of blood concentration occurred 2 min after nasal administration of esketamine hydrochloride； cmax was （814.58±418.80） ng/mL， AUC0－∞ was （203.75± 92.76） ng·h/mL， and the absolute bioavailability was 60.68%. After nasal administration of esketamine hydrochloride， it was observed that the cilia of bullfrog were arranged neatly， the edges were clear， the cilia tissue structure was complete and the cilia moved actively. The cilia movement time was （178.17±13.30） min for the first time， and after the cilia moved again， the ciliary movement time measured again was （24.50±9.19）min with a relative movement percentage of 53.56%. CONCLUSIONS Esketamine hydrochloride nasal spray has a rapid onset of action， high bioavailability， and low ciliary toxicity.

Objective To investigate the value of thrombomodulin(TM),thrombin-antithrombin complex(TAT),α2 plasmin inhibitor-plasmin complex(PIC)and tissue plasminogen activator-inhibitor complex(t-PAIC)in the diagnosis and prognosis of neonatal disseminated intravascular coagulation(DIC).Methods Eighty-seven DIC neonates(the observation group)were included and divided into the survival group(66 cases)and the death group(21 cases)based on their outcomes at discharge.And 50 healthy newborns born in the same period were selected as the control group.The clinical data of neonates were collected,and risk factors of neonatal DIC were analyzed by Logistic regression.The differences of TM,TAT,PIC and t-PAIC levels in different groups were analyzed.The receiver operating characteristic(ROC)curve was used to analyze values of TM,TAT,PIC and t-PAIC in the diagnosis and prognosis of neonatal DIC.Results The incidence of low Apgar score,birth asphyxia,IVH,sepsis and maternal pregnancy induced hypertension syndrome(PIH)were higher in the observation group than those in the control group(P＜0.05).Multivariate Logistic regression analysis showed that low Apgar score,birth asphyxia,sepsis and PIH were independent risk factors for neonatal DIC.TM,TAT,PIC and t-PAIC levels were higher in the observation group than those in the control group(P＜0.05).ROC curve showed that the combined diagnosis value of TM,TAT,PIC and t-PAIC was better than that of single diagnosis of neonatal DIC.TM and TAT levels were higher in the death group than those in the survival group(P＜0.05),and there were no significant differences in PIC and t-PAIC levels between the two groups.Multivariate Logistic regression analysis showed that elevated TAT level was an independent risk factor for neonatal DIC prognosis.ROC curve showed that when TAT was 21.72 μg/L,the area under the curve for predicting neonatal DIC prognosis was 0.772(95%CI:0.666-0.878),and the sensitivity and specificity were 76.2%and 71.2%,respectively.Conclusion The combined application of TM,TAT,PIC and t-PAIC has important clinical value in diagnosis and prognosis evaluation of neonatal DIC.

BACKGROUND:At present,a large number of studies have found that Liuwei Dihuang Pill can be used to treat osteoporosis,but there are few related studies on the differentiation and mineralization of osteoblasts induced by wear particles using Liuwei Dihuang Pill. OBJECTIVE:To investigate the positive effect of different concentrations of Liuwei Dihuang Pill-containing serum on titanium particle-induced mouse MC3T3-E1 osteoblast in vitro osteolysis model. METHODS:Drug-containing serum was extracted after oral administration of Liuwei Dihuang Pill.The best concentration of Liuwei Dihuang Pill-containing serum and titanium particles on the viability of MC3T3-E1 cells was screened.MC3T3-E1 cells were divided into three groups.The blank group was given osteoblastic differentiation culture.The model group was given titanium particles(5 μg/mL)ossification culture.The drug-containing serum group was given titanium particles(5 μg/mL)+ Liuwei Dihuang Pill-containing serum(10%,15%and 20%doses).Osteoblast viability was detected by CCK-8 assay.Cell alkaline phosphatase activity was detected by alkaline phosphatase staining.Cell mineralization was detected by silver nitrate(Von Kossa)and alizarin red staining.Expression levels of bone differentiation-related genes Runx-2,Osterix,Ocn,Axin,Alp,and Opn were detected by qRT-PCR.Wnt/β-catenin signaling pathways β-catenin,p-GSK-3β,GSK-3β,Runx2 and Osterix protein expression levels were detected by western blot assay. RESULTS AND CONCLUSION:(1)Liuwei Dihuang Pill-containing serum culture reversed the decrease in alkaline phosphatase activity of MC3T3E-1 cells induced by titanium particles,increased the alizarin red staining and calcification of MC3T3E-1 cells,increased the expression of osteogenesis-related genes in MC3T3E-1 cells,and increased the expression of proteins related to the Wnt/β-catenin signaling pathway.(2)These findings indicate that Liuwei Dihuang Pill-containing serum can reverse the inhibitory effect of titanium particles on the differentiation and mineralization of osteoblasts,upregulate the expression of osteogenesis-related genes,and its mechanism is related to the regulation of Wnt/β-catenin signaling pathway,suggesting that Liuwei Dihuang Pill is expected to become an effective drug for preventing aseptic loosening of artificial joints.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective To investigate the role and mechanism of circular RNA SNRK (circSNRK) in ischemia-reperfusion injury (IRI). Methods A hypoxia-reoxygenation (IRI) cell model was established. The expression level of circSNRK after IRI treatment and the effect of overexpression of circSNRK on cell proliferation and apoptosis were detected. The targets of circSNRK were identified. HK2 cells were divided into the blank group (Mock group), IRI group, control plasmid+IRI group (IRI+NC group), human circSNRK overexpression+IRI group (IRI+circSNRK group), human circSNRK overexpression+IRI+protein kinase B (Akt) inhibitor group (IRI+circSNRK+MK2206 group) and control plasmid group (NC group). Cell proliferation and apoptosis were detected in the Mock, IRI, IRI+NC and IRI+circSNRK groups. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses of the target of circSNRK were carried out. The expression levels of CDKN1A, Akt, B-cell lymphoma (Bcl)-2, cysteinyl aspartate specific proteinase (Caspase)-9 messenger RNA (mRNA), and those of p21, Bcl-2, Caspase-9, Akt and p-Akt proteins were detected in the Mock, IRI, IRI+NC and IRI+circSNRK groups, respectively. Cell proliferation and apoptosis were determined in the NC, IRI+NC, IRI+circSNRK and IRI+circSNRK+MK2206 groups. Results Compared with the Mock group, the expression level of circSNRK was lower, and cell proliferation capability of HK2 cells was decreased and cell apoptosis was increased in the IRI group. In the IRI+circSNRK group, cell proliferation capability was higher, whereas cell apoptosis was lower than those in the IRI+NC group. circSNRK could act on 648 targets through 51 microRNAs (miRNAs). GO enrichment analysis revealed that the targets of circSNRK were mainly enriched in biological processes (such as cell process and biological regulation), cell components (such as cell parts, cells and extracellular parts), and molecular functions (such as binding, binding proteins and enzymes). KEGG enrichment analysis showed that the targets of circSNRK were mainly enriched in cancer signaling pathway, phosphatidylinositol 3-kinase (PI3K)-Akt signaling pathway, miRNA in cancer and other related signaling pathways. Compared with the Mock group, the relative expression levels of CDKN1A and Caspase-9 mRNA were higher, the expression level of miR-99a-5p RNA was higher and the relative expression levels of Akt and Bcl-2 mRNA were lower in the IRI group. Compared with the IRI+NC group, the relative expression levels of CDKN1A and Caspase-9 mRNA were lower, those of Akt and Bcl-2 mRNA were higher, and the expression level of miR-99a-5p RNA was lower in the IRI+circSNRK group, and the differences were statistically significant (all P < 0.05). Compared with the Mock group, the expression levels of p21 and Caspase-9 proteins were higher, while those of p-Akt, Akt and Bcl-2 proteins were lower in the IRI group. Compared with the IRI+NC group, the expression levels of p21 and Caspase-9 proteins were lower, whereas those of p-Akt, Akt and Bcl-2 proteins were higher in the IRI+circSNRK group. The miR-99a-5p binding sites were observed in circSNRK and Akt. Compared with the NC group, cell proliferation capability was declined in the IRI+NC group. Compared with the IRI+NC group, cell proliferation capability was elevated in the IRI+circSNRK group. Compared with the IRI+circSNRK group, cell proliferation capability was declined in the IRI+circSNRK+MK2206 group (all P < 0.05). The cell apoptosis level in the IRI+NC group was higher than that in the NC group. The cell apoptosis level in the IRI+circSNRK group was lower compared with that in the IRI+NC group. The cell apoptosis level in the IRI+circSNRK+MK2206 group was higher than that in the IRI+circSNRK group. Conclusions Under IRI conditions, circSNRK may affect the proliferation and apoptosis of HK2 cells probably via the Akt signaling pathway.
