Study of the mechanism of acupuncture and moxibustion in protecting the intestinal mucosal barrier in DSS-induced UC rats based on the IL-9/IL-9R pathway / 针灸推拿医学（英文版）

Objective:To observe the effects of acupuncture and moxibustion on interleukin(IL)-9/IL-9 receptor(IL-9R)in the colon tissue of rats with ulcerative colitis(UC)and investigate the protective mechanism of acupuncture and moxibustion on the intestinal mucosal barrier in UC rats. Methods:Male Sprague-Dawley rats were randomly divided into a normal control(NC)group and a modeling group.UC models were prepared by giving 4%dextran sulfate sodium(DSS)water for 7 d.After the successful construction of the UC rat model,the modeling group was randomly divided into a UC group,a herb-insulated moxibustion(HM)group,and an electroacupuncture(EA)group.HM and EA interventions at bilateral Tianshu(ST25)were performed once a day for 7 d.Hematoxylin-eosin(HE)staining was used to observe the histopathological changes in the colon.The serum concentrations of IL-9,IL-6,IL-1β,and hemoglobin-H(HbH)were determined by enzyme-linked immunosorbent assay.The protein expression levels of IL-9,IL-9R,claudin-2,zonula occludens-1(ZO-1),and occludin in the colon tissue were measured by Western blotting or immuno-histochemistry.Immunofluorescence was used to detect the co-expression of PU.1 and CD4 with the IL-9 protein. Results:Compared with the NC group,the colon tissue of UC rats was severely damaged and ulcerated with congestion and edema,and the colonic histopathological score increased significantly(P<0.01).The serum HbH concentration decreased significantly(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β increased(P<0.01).The protein expression of colonic ZO-1 and occludin decreased significantly(P<0.01),while the protein expression of colonic IL-9 and IL-9R increased(P<0.05).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 increased in the colon tissue(P<0.05).Compared with the UC group,the colonic mucosal structures were gradually repaired in both HM group and EA group,and healed ulcers could be observed,the colonic histopathological score decreased significantly(P<0.05).The serum concentration of HbH increased(P<0.01),while the serum concentrations of IL-9,IL-6,and IL-1β decreased(P<0.05).The protein expression levels of ZO-1 and occludin increased(P<0.05),while the protein expression levels of IL-9 and IL-9R decreased(P<0.01).The positive co-expression levels of IL-9/PU.1 and IL-9/CD4 decreased in the colon tissue(P<0.05). Conclusion:Both HM and EA can inhibit the protein expression levels of IL-9 and IL-9R in the UC colon by regulating the transcription factor PU.1,promote the repair of intestinal mucosal barrier,and down-regulate protein contents of proinflammatory factors IL-9,IL-6,and IL-1β in the serum,which may be one of the key mechanisms of acupuncture and moxibustion in reducing the inflammation of UC colonic mucosa and protecting the intestinal mucosal barrier.

Quantitative analysis of the developmental potential of cells and tissues based on evolutionary conservation of genes and regulatory regions / 上海交通大学学报（医学版）

Objective·To study the relationship between evolution and the developmental process from the perspective of DNA sequence conservation,and explore their inherent principles.Methods·First,conservation rate(CR)was established by analyzing the conservation of amino acid sequences of coding genes in 100 species to quantify the evolutionary conservation of genes.The relationship between CR and developmental potential was verified by using the feature genes involved in embryonic stem cells pathways.Secondly,cell type-specific genes and their characteristics in conservation were studied by analyzing the RNA sequencing(RNA-seq)data of the three early germ layers(ectoderm,mesoderm and endoderm)and their corresponding mature organs(brain,heart,liver,etc).Then,chromatin immunoprecipitation sequencing(ChIP-seq)data of enhancer histone H3 acetylated at lysine 27(H3K27ac)from early germ layers and mature organs were collected to search for enhancer sites and identify super enhancers in various cells and tissues by using the ROSE procedure.Functional enrichment and signaling pathway analysis of genes was used to examine the identity correlation between SEs-regulated genes and the corresponding cell characteristics,to clarify whether the SEs identified in this study were consistent with the characteristics reported in previous studies.Finally,PhastCons program was used to calculate the DNA conservation score(CS)of non-coding regulatory regions to study their relationship with developmental potential.Results·In the coding region of DNA,CR was successfully established to quantify the conservation of genes.The gene expression data of early germ layers and mature organs showed that the genes with higher conservation rate were more relevant to the stemness and early developmental process,and the differences between the tissues from early and late development could be distinguished by using CR.In the non-coding regions of DNA,it was found that the conservation of regulatory regions was also correlated with development.The CS of the SE sequences in the early developmental germ layers was significantly higher than that of the SE sequences in the corresponding mature organs.However,cell-specific typical enhancers(TEs)did not show such a trend.Conclusion·During the developmental process,CR of genes expressed in the coding region decreases,and CS of super-enhancer DNA in the non-coding region decreases.

Objective:To observe the effects of acupuncture and moxibustion on phosphatase and PTEN-induced putative kinase 1(PINK1)/Parkin signaling pathway in the midbrain substantia nigra of Thy1-α synuclein(αSyn)transgenic model mice with Parkinson disease(PD). Methods:Twenty-four Thy1-αSyn transgenic mice were randomly divided into a model group,an acupuncture group,an acupuncture + moxibustion group,and a Western medicine group.Six wild-type mice in the same litter were used as the wild-type group.In the acupuncture group,Baihui(GV20)and Yanglingquan(GB34)were selected for acupuncture.In the acupuncture + moxibustion group,Guanyuan(CV4)was added on the basis of the acupuncture group.The Western medicine group was given rapamycin intraperitoneal injection at a dose of 10 mg/(kg·bw).The wild-type group and the model group were fixed without intervention.The overall rod performance(ORP)score of mice was observed in each group.The immunohistochemical method was used to detect the tyrosine hydroxylase(TH)positive neurons in the substantia nigra of mice in each group.The αSyn was detected by the immunofluorescence chemical method.The expression levels of αSyn,microtubule-associated protein 1 light chain 3(LC3)-Ⅱ/LC3-Ⅰ,autophagy protein sequestosome-1/protein 62(SQSTM-1/p62),PINK1,Parkin,and ubiquitin-specific protease 30(USP30)proteins were detected by Western blotting assay.The expression levels of LC3B,p62,PINK1,Parkin,and USP30 mRNAs were detected by fluorescence quantitative polymerase chain reaction. Results:Compared with the wild-type group,the ORP score,the p62,PINK1,and Parkin protein expression levels decreased significantly(P<0.01),the PINK1 mRNA expression level decreased(P<0.05),while the protein and mRNA expression levels of USP30 increased(P<0.05)in the model group.Compared with the model group,the ORP score in the acupuncture group and the acupuncture + moxibustion group increased(P<0.05);the expression level of LC3-Ⅱ/LC3-Ⅰ protein in the acupuncture + moxibustion group and the Western medicine group increased(P<0.05);the protein expression levels of p62,PINK1,and Parkin increased(P<0.05),while the USP30 protein expression level decreased significantly(P<0.01)in the acupuncture group,the acupuncture + moxibustion group,and the Western medicine group;the Parkin mRNA expression level in the acupuncture group and the acupuncture + moxibustion group increased(P<0.05);the USP30 mRNA expression level in the acupuncture + moxibustion group decreased(P<0.05). Conclusion:Acupuncture and moxibustion regulate the related molecule expression levels of PINK1/Parkin signaling pathway in the Thy1-αSyn transgenic PD model mice and promote the autophagy degradation of αSyn to exert the protective effect of dopaminergic neurons.

Randomized controlled trials of acupuncture for the treatment of essential hypertension:a meta-analysis / 针灸推拿医学（英文版）

Objective:To systematically assess the efficacy and safety of acupuncture therapy for essential hypertension.Methods:A computerized literature search of the Chinese National Knowledge Infrastructure(CNKI),Chongqing VIP Database(CQVIP),Wanfang Academic Journal Full-text Database(Wanfang),China Biology Medicine Disc(CBM),PubMed,Excerpta Medica Database(EMBASE),and Cochrane Library was conducted to retrieve randomized controlled clinical trials on acupuncture as the main intervention for the treatment of essential hypertension published from the inception of the database to 30 January 2021.The risk-of-bias assessment was carried out for each included study according to the Cochrane Handbook.Data analysis was performed using Review Manager 5.4.1 and Stata 15.0.Results:After the screening,46 randomized controlled trials involving a total of 3 859 subjects were included.Primary outcomes included changes in the diastolic blood pressure after intervention[eight studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[mean difference(MD)=1.45,95%confidence interval(CI)(0.48,2.43),P=0.004,fixed effects model;I2=39%]and changes in the systolic blood pressure after intervention{11 studies showed that the acupuncture plus antihypertensive drug group was better than the antihypertensive drug monotherapy group[MD=8.60,95%CI(7.12,10.07),P<0.00001,fixed effects model;I2=26%]}.The secondary outcome was antihypertensive efficacy,12 studies of acupuncture monotherapy group[risk ratio(RR)=1.20,95%CI(1.12,1.28),P<0.00001,fixed effects model;I2=36%]and 15 studies of acupuncture combined with antihypertensive drug group[RR=1.27,95%CI(1.20,1.34),P<0.00001,fixed effects model;I2=6%]showed better results than the antihypertensive drug monotherapy group in antihypertensive efficacy.In terms of the adverse events,four studies showed that the acupuncture monotherapy group had fewer adverse events than the antihypertensive drug monotherapy group[RR=0.10,95%CI(0.04,0.25),P<0.00001,fixed effects model;I2=0%].Conclusion:Acupuncture combined with antihypertensive drugs is superior to antihypertensive drugs alone in reducing blood pressure,and acupuncture therapy is effective and safe for the treatment of essential hypertension with fewer side effects.However,there is still a lack of high-quality multicenter randomized double-blinded controlled trials in this field.Rigorous large-sample clinical trials are needed to validate these findings.

Conjugated linoleic acid improves glucose and lipid metabolism in diabetic mice / 南方医科大学学报

OBJECTIVE@#To analyze the effect of conjugated linoleic acid (CLA) on glucose and lipid metabolism in obese diabetic (db/db) mice.@*METHODS@#db/db mice were randomized for treatment with saline or CLA mixture administered intragastrically. The changes in body weight, dietary intake, water intake, oral glucose tolerance, triglyceride and total cholesterol were recorded after the treatments. HE staining and oil red O staining were used to assess liver pathologies and fatty acid content. The expression levels of PPARα, PPARγ, CD36, CHREBP and SREBP-1c were detected using real-time PCR and Western blotting. HepG2 cells were treated with CLA and linoleic acid and the expressions of PPARα, ACC, P-ACC, and CD36 were detected; the level of acetyl-CoA in the cell supernatant was detected using ELISA.@*RESULTS@#CLA treatment obviously reduced the dietary and water intake of db/db mice, effectively reduced the body weight and decreased serum triglyceride and cholesterol levels ( < 0.05). CLA significantly reduced fasting blood glucose, increased glucose tolerance, reduced the accumulation of lipid droplets in the liver and improved lipid metabolism in db/db mice. The mice showed significantly increased expression of PPARα ( < 0.05) and lowered CD36 expression ( < 0.001) in the liver after CLA treatment. Cellular experiments showed that CLA significantly up-regulated PPARα ( < 0.001) and P-ACC and decreased the expression of CD36 ( < 0.01). ELISA showed that acetyl-CoA was significantly up-regulated in the cells after CLA treatment ( < 0.01).@*CONCLUSIONS@#The mixture of two conjugated linoleic acid isomers can reduce fasting blood glucose, increase glucose tolerance and improve glycolipid metabolism in db/db mice by enhancing the expression of PPARα, increasing P-ACC and inhibiting CD36 expression.

Effects of Treadmill Running on Intramyocellular Lipid Deposition and VEGFB Expression in Soleus Muscle of High-fat Diet Mice / 中国运动医学杂志

Objective To observe the effect of treadmill running on skeletal muscle lipid deposition,and the expression of vascular endothelial growth factor-B(VEGFB)and its receptor in soleus muscles of high-fat diet mice.Methods Thirty-two 5-week-old C57BL/6 male mice were randomly divided into a control group(n=8)and a high-fat diet group(n=24),and fed with normal and high-fat diet respectively.Eight weeks later,16 obesity mice were selected from the latter group and randomly divided into a sedentary group(n=8)and a treadmill running group(n=8).The running group underwent treadmill running at 25 m/min for an hour every day,five days a week for 8 weeks,while the other two groups did not do any exercises.The weight was measured before the mice were killed.The soleus lipid deposition level was determined using oil red O staining,The expression of VEGFR1 and Neuropilin-1(NRP1)was determined using the immunohistochemical staining,while the mRNA expression of VEGFB,VEG-FR1,NRP1 and peroxisome proliferator-activated receptor-γcoactivator-1α (PGC-1α) was detected using the real-time PCR.Results Compared with the control group,a significant increase was observed in the weight and the soleus lipid deposition of the high-fat diet group,while there were no significant differences in the expression of VEGFB,NRP1,VEGFR1 and PGC-1α.mRNA between the two groups.Compared with the sedentary obese mice,significant decrease in the body weight and soleus lipid deposition,significant increase in VEGFR1 mRNA expression,but no significant changes in the expression of VEGFB,NRP1 and PGC-1α mRNA were observed in the treadmill-running obese mice.Conclusion The treadmill running has no effect on the VEGFR1 expression in soleus of obese mice,but significantly up-regulates the expression of its receptors.It indicates that the treadmill running can lower the intramyocellular lipid deposition as it can strengthen the VEGFB/VEGFR1 in soleus muscles.

Application of problem-based learning in dermatology and venereology teaching of clinical medicine / 中华医学教育探索杂志

Objective To explore the application of PBL in dermatology and venereology teaching. Method According to random principle, 120 students were divided into experimental group and control group (60 students per group). The experimental group received PBL, and the control group received tradi-tional teaching. The teaching contents included systemic lupus erythematosus, pemphigus, psoriasis, syphilis. The course needed 16 periods totally . the traditional teaching group applied 8 classes extensive class teaching and 8 classes clinical trainee, and the PBL teaching group implemented case-based teaching 4 hours each time. Teaching satisfaction evaluation and test scores would be analyzed at the end of the semester. SPSS 17.0 was used for t test. Results The teaching satisfaction (contains professional values and ethics, communication skills, clinical skills, community health and health systems, information management, critical mind and research, etc.) of experimental group was higher than control group (P<0.05); The test scores of experimental group was higher than control group (P<0.05), especially in total score of theoretical examina-tion, comprehension and application. The difference mainly came from PBL teaching (P<0.05). Conclusion PBL is conductive not only to the comprehension and application of knowledge but to training the students' abilities of independent learning.

The role of different KIR haplotypes in haplo-identical hematopoietic stem cell transplantation / 中华血液学杂志

<p><b>OBJECTIVE</b>To investigate the role of different immunoglobulin- like receptor (KIR)haplotypes in haplo- identical hematopoietic stem cell transplantation (HSCT).</p><p><b>METHOD</b>Killer cell KIR genotyping was performed on 468 individuals from 156 unrelated families by PCR-SSP. A total of 624 KIR haplotypes from the parents were used for haplotype analysis. Ninety-two patients received haplo-identical HSCT from one of the parents.</p><p><b>RESULTS</b>The family study showed segregation of one A haplotype and at least 20 unique B haplotypes. The frequency of haplotype A was 72.92% (455/624). The most commonly observed haplotypes in group B were B1, B2, and B3, present at a frequency of 10.26%, 5.77%, and 4.48%, respectively. Compared to KIR gene matched donors (n=17), grafts from KIR gene mismatched donors (n= 14) had a positive effect on survival after haplo- identical HSCT for AML/MDS patients (OS: 88.2%vs 42.9%,P=0.015; RFS: 88.2%vs 35.7%,P=0.007). No effect was observed for ALL/NHL patients (OS: 76.0%vs 75.0%,P=0.727; RFS: 68.0%vs 65.0%,P=0.866). A significantly lower survival rate was observed for transplants from AA (n=52) and AB1/AB2 donors (n=15), compared to other group Bx donors (n=25) (OS: 53.3%vs 96.0%,P=0.017; RFS: 53.3%vs 92.0%,P=0.019). Meanwhile, the risk of relapse was much higher in AA group (n=52) compared to Bx group (n=40) (25.0%vs 5.0%,P=0.009). A higher risk of TRM was observed in AB1/AB2 group (P=0.012). In addition, transplant from donors carried Cen-B was associated with an increased survival compared with Cen-A homozygous donors (OS: 94.7%vs 68.5%,P=0.036; RFS: 89.5%vs 64.4%,P=0.045).</p><p><b>CONCLUSION</b>Overall, KIR genotyping and haplotype analyses should be useful for selection of the most optimal donors with favorable KIR gene grafts. KIR gene mismatch donors should be preferred for AML/MDS patients. Selecting donors carried Cen- B and avoiding the selection of donors of KIR genotype AA/AB1/AB2 was strongly advisable for haplo-identical HSCT.</p>

A study of the frequencies of HLA-DQA1 alleles and their clinical application values in the donor-recipient HLA-10/10 matched hematopoietic stem cell transplantation / 中华微生物学和免疫学杂志

Objective To analyze the frequencies of HLA-DQA1 alleles and their clinical values in the donor-recipient HLA-A,-B,-C,-DRB1,-DQB1 (10/10) matched hematopoietic stem cell transplantation (HSCT).Methods This study recruited 127 patients who received allogeneic HSCT and 127 unrelated donors.High-resolution (High Res) DNA typing for HLA-DQA1 alleles were performed on the 254 subjects by using sequence specific oligonucleotide probes (SSOP) and high resolution of sequence specific primer(High Res SSP).Results The DQA1 allele genotypes of 36 pairs of donor-recipient were directly identified by using SSOP.The ambiguous DQA1 allele genotypes of the rest 91 pairs were identified by using High Res SSP.Among the 127 pairs of donor-recipient,5 pairs were HLA-DQA1 alleles mismatched,while the others were all matched.No significant differences in the distribution of HLA-DQA1 alleles were observed between the donors and the recipients.Sixteen HLA-DQA1 alleles were detected in the 127 donors,which were DQA1 * 02 ∶ 01 (19.3％),DQA1* 01 ∶ 02(19.3％),DQA1 * 03 ∶ 02/03 (17.0％),DQA1 *01∶03 (9.8％),DQA1*06∶01(9.1％),DQA1*05∶ 01(7.1％),DQA1*05∶05(5.9％),DQA1*03∶01 (4.7％),DQA1*01 ∶04(2.4％),DQA1*01∶05(2.0％),DQA1*01∶01(1.2％),DQA1*05 ∶ 03(0.8％),DQA1 *05 ∶ 08(0.8％),DQA1*04 ∶ 01(0.4％),DQA1*05 ∶ 06(0.4％) from high to low frequency.Moreover,a new allele was detected in the patients.The haplotypes' frequencies and linkage disequilibrium(LD) analysis of HLA-DQA1 and HLA-DQB1 showed that the most common haplotype was DQA1 *02 ∶ 01-DQB1 *02 ∶ 02(16.1％),followed by DQA1 *03 ∶ 02/03-DQB1 *03 ∶ 03 (11.8％)and DQA1 *01 ∶ 03-DQB1 * 06 ∶ 01 (9.1％).Stronger LD were observed between DQA1 * 02 ∶ 01 and DQB1*02 ∶ 02,DQA1 *03 ∶ 02 and DQB1*03 ∶ 03,DQA1 *01 ∶ 03 and DQB1*06 ∶ 01,HLA-DQA1*06∶01 andDQB1*03 ∶ 01,DQA1*05 ∶ 01 and DQB1*02 ∶ 02(P＜0.001).Conclusion There was strong linkage disequilibrium between HLA-DQA1 and HLA-DQB1 genes.The polymorphism of HLA-DQA1 gene was less than that of HLA-DQB1 gene.No more guidance was provided to donor selection in unrelated donor-recipient HLA matched HSCT by adding HLA-DQA1 genotyping,but it might have clinical application values in HSCT with HLA Ⅱ locus mismatched donor and recipient.
