RESUMEN
Objective To investigate the expression of inflammatory factors and brain-derived neurotro-phic factor(BDNF)in the brain hippocampus of Alzheimer's disease(AD)-like mice caused by amyloid β-protein 25-35(Aβ25-35).Methods A total of 40 six-week-old male Kunming mice were taken to construct an AD-like mouse model using bilateral ventricular injection of Aβ25-35,and were divided into the 0 d,7 d,14 d,and 28 d groups for observation,with 10 mice in each group.The Y-maze and new object recognition assay were used to test the learning and memory functions of the mice.The hematoxylin-eosin(HE)staining was used to observe the neuronal damage in the hippocampal region.Immunohistochemical staining was used to detect the expression levels of phosphorylated-tau(p-tau),CD11b and BDNF in hippocampus.ELISA was used to detect the expression levels of inflammatory factors in hippocampus,including interleukin-1β(IL-1β)and tumor necrosis factor-α(TNF)-α,and real-time quantitative reverse transcription PCR(RT-qPCR)and Western blot were used to detect the mRNA and protein expression levels of BDNF.Results Aβ25-35 could impair memory and cognitive function in the mice.Compared with the 0 d group,the neuron number in the hippocampal tissue of mice in the 14 d and 28 d groups was significantly reduced(P<0.05),and the optical density values of p-Tau and CD11b,and expression levels of IL-1β and TNF-α in the hippocampal region of mice in the 14 d and 28 d groups were significantly increased(P<0.05).In addition,compared with the 0 d group,the relative expression levels of BDNF mRNA and protein in the hippocampal tissue of mice were sig-nificantly increased in the 7 d group(P<0.05),while the relative expression levels of BDNF mRNA and pro-tein were significantly decreased in the 14 d and 28 d groups(P<0.05).Conclusion Aβ25-35 may increase the expression of TNF-α,IL-1β and p-tau in hippocampal tissue by activating microglia,which in turn impaired the memory and cognitive functions of mice,and the expression level of BDNF in hippocampal tissue showed a first increase and then a decrease in the injury period.

RESUMEN
Based on the literature study,the thoughts and possible therapeutic mechanism in treating male infertility from the perspective of spleen and kidney by regulating intestinal flora were explored.Disturbance of intestinal flora is one of the important factors leading to the development of male infertility,and the spleen and kidney have certain similarities to intestinal flora in the physiological function and pathological changes.Moreover,tonifying the kidney and strengthening the spleen can regulate the intestinal flora by fostering the growth of beneficial bacteria,inhibiting the reproduction of pathogenic bacteria,and protecting the barrier of the intestinal mucosa.Therefore,the possible therapeutic mechanisms in treating male infertility with the prescriptions for tonifying the kidney and strengthening the spleen to regulate intestinal flora are as follows:inhibiting the expression of inflammatory factors to reduce the inflammatory reaction of testicular tissues;improving the antioxidant capacity to alleviate the damage of spermatozoa caused by oxidative stress,and improving the bad mood to alleviate the impact of psychological stress on the reproductive system.The exploration of the thoughts for treating male infertility from the perspective of spleen and kidney by regulating intestinal flora may provide a new entry point for modern Chinese medicine clinical treatment of male infertility.

RESUMEN
Diabetic retinopathy(DR)is considered to be a chronic medium-and low-grade inflammatory disease(mi-croinflammation).Inflammation runs through the entire process of DR,manifesting as an increase in ocular and systemic inflammation biomarkers.In the eyes of DR patients,there is an increase in pro-inflammatory mediators,such as interleu-kin(IL)-1 β,IL-6 and tumor necrosis factor-α,as well as activated and increased number of inflammatory cells,such as ac-tivated microglia,Müller cells in the retina,and infiltration of mononuclear macrophage.In addition,immunocytes are also involved in the pathogenesis of DR,such as the involvement of circulating T cells in leukostasis.These indicate that chronic inflammation is an inducing factor of DR,with multiple inflammation-related factors participating and influencing each other,leading to the destruction of the blood-retinal barrier and neuronal injury and exacerbating the development of DR.There-fore,personalized anti-inflammatory therapy is of great significance in the treatment of DR.

RESUMEN
@#Objective: To explore the balance of peripheral blood T helper 17 cells/regulatory T cell (Th17/Treg) ratio and the polarization ratio of M1 and M2 macrophages in lower extremity arteriosclerosis obliterans (ASO). Methods: A rat model of lower extremity ASO was established, and blood samples from patients with lower extremity ASO before and after surgery were obtained. ELISA was used to detect interleukin 6 (IL-6), IL-10, and IL-17. Real-time RCR and Western blot analyses were used to detect Foxp3, IL-6, IL-10, and IL-17 expression. Moreover, flow cytometry was applied to detect the Th17/Treg ratio and M1/M2 ratio. Results: Compared with the control group, the iliac artery wall of ASO rats showed significant hyperplasia, and the concentrations of cholesterol and triglyceride were significantly increased (P<0.01), indicating the successful establishment of ASO. Moreover, the levels of IL-6 and IL-17 in ASO rats were pronouncedly increased (P<0.05), while the IL-10 level was significantly decreased (P<0.05). In addition to increased IL-6 and IL-17 levels, the mRNA and protein levels of Foxp3 and IL-10 in ASO rats were significantly decreased compared with the control group. The Th17/Treg and M1/M2 ratios in the ASO group were markedly increased (P<0.05). These alternations were also observed in ASO patients. After endovascular surgery (such as percutaneous transluminal angioplasty and arterial stenting), all these changes were significantly improved (P<0.05). Conclusions: The Th17/Treg and M1/M2 ratios were significantly increased in ASO, and surgery can effectively improve the balance of Th17/Treg, and reduce the ratio of M1/M2, and the expression of inflammatory factors.

RESUMEN
ObjectiveTo explore the clinical effectiveness and safety of stick-point sinew-soothing and bone-setting manipulation for scapulohumeral periarthritis. MethodsUsing prospective randomised controlled trial method， 60 cases of patients with scapulohumeral periarthritis were collected and randomly divided into 30 cases each in control group and trial group. Both groups of patients were orally treated with celecoxib， on the basis of which the control group was treated with traditional bonesetting manipulation once every other day for 14 days， while the trial group was treated with stick-point sinew-soothing and bone-setting manipulation once every 3~5 days for 14 days. Both groups were treated for 2 courses. The main observation indexes were pain visual analogue scale （VAS） score and shoulder pain and dysfunction index （SPADI）， which were evaluated once before treatment and after 2 and 4 weeks of treatment. The secondary effectiveness indicators included the university of California at Los Angeles shoulder rating scale （UCLA）， traditional Chinese medicine syndrome score （including symptom scores as joint pain， pain in a fixed place， activity limitation， local stiffness）， and serum interleukin （IL-6） and tumour necrosis factor α （TNF-α） levels before and after the treatment， in order to evaluate the clinical effectiveness， and to record the adverse reactions that occurred in the process of diagnosis and treatment. ResultsCompared with the groups before treatment， the pain VAS score， SPADI and scores of joint pain， pain with a fixed place， activity limitation and local stiffness were lower， UCLA score was higher， and serum IL-6 and TNF-α levels were lower at 4 weeks of treatment in the two groups （P＜0.05）. When comparing the two groups between the groups at 2 and 4 weeks of treatment， the pain VAS score， SPADI and TCM scores of each symptom in the study group were lower than those in the control group， the UCLA score was higher than those in the control group （P＜0.01）， and the serum IL-6 and TNF-α levels were lower than those in the control group at 4 weeks of treatment （P＜0.01）. The clinical effectiveness rate of the study group was 66.67%， which was significantly higher than that of the control group， which was 40.00% （P = 0.038）. No adverse reactions were seen in both groups during the study. ConclusionCompared with the traditional massage manipulation， the treatment of scapulohumeral periarthritis with stick-point sinew-soothing and bone-setting manipulation has more advantages in relieving pain symptoms， reducing inflammatory reaction， and promoting the recovery of shoulder joint function.
RESUMEN
ObjectiveTo investigate the effect of total alkaloids of Corydalis saxicola on a rat model of lipopolysaccharide（LPS）-induced depression， as well as the pharmacokinetic characteristics of 8 of its major components. MethodTwenty-four male SD rats were randomly divided into normal group， model group， fluoxetine group（10 mg·kg-1） and total alkaloids of C. saxicola group（210 mg·kg-1）， with 6 rats in each group. In addition to the normal group， the rats were injected intraperitoneally with LPS to establish the inflammation model of depression， and the drug administration was started 1 week after modeling， and the administration groups were gavaged according to the corresponding dose， and the normal and model groups were intragastric administration with equal volume of distilled water， and the administration was performed along with the modeling. After two weeks of continuous administration， the effect of total alkaloids of C. saxicola on the behavior of depressed rats were tested by sucrose preference， forced swimming and open field experiments， the levels of tumor necrosis factor-α（TNF-α）， interleukin（IL）-1β and IL-6 in serum of rats were determined by enzyme-linked immunosorbent assay（ELISA）， the histopathological changes of rat hippocampus were observed by hematoxylin-eosin（HE） staining. After the last administration， blood was collected from orbit according to the set time， and ultra-high performance liquid chromatography-triple quadrupole tandem mass spectrometry（UPLC-QqQ-MS） was established to simultaneously detect the concentrations of dehydrocavidine， tetrahydropalmatine， coptisine， palmatine， jatrorrhizine， berberine， berberrubine and epiberberine in plasma， and drug-time curves were drawn. The pharmacokinetic parameters were analyzed by DAS 2.0 software. ResultCompared with the normal group， the model group exhibited a decrease in sucrose preference rate， total distance traveled in the open field， as well as an increase in swimming immobility time and serum inflammatory factor expression（P<0.01）. In contrast， compared with the model group， rats in each administration group showed an increase in sucrose preference rate and total distance traveled in the open field， a decrease in swimming immobility time， and a reduction in serum inflammatory factor expression（P<0.05， P<0.01）. Additionally， HE staining results revealed that neurons in the hippocampus of rats from the model group were characterized by loss， disorganization and residual vacuoles， whereas those from the total alkaloids of C.saxicola group displayed an increase in number with orderly arrangement and clear cytoplasm. Pharmacokinetic results showed that the time to peak（tmax） and half-life（t1/2） of the 8 active ingredients were 0.19-2.06 h and 3.71-8.70 h after continuous administration of total alkaloids of C. saxicola. Among them， the area under the curve（AUC0-∞） of tetrahydropalmatine was the highest and the t1/2 was the shortest， and the AUC0-∞ of coptisine， palmatine， jatrorrhizine， berberine， berberrubine and epiberberine were low. The curves of dehydrocavidine， coptisine， palmatine， berberine and epiberberine showed obvious double peak phenomenon. ConclusionTotal alkaloids of C. saxicola can improve the depression-like behavior of rats， inhibit the expression of inflammatory factors in serum， improve the pathological injury of hippocampus， and has the antidepressant effect. Meanwhile， the effective site is absorbed quickly and eliminated slowly in the depressed model rats， and the efficacy is maintained for a long time.
