Associations of TNF-RII rs1061622 With Post-Traumatic Stress Disorder and Their Interplays on Serum Lipids Levels in Adolescents

Objective@#To verify effects of rs1061622 at tumor necrosis factor-α receptor II (TNF-RII) gene (TNF-RII) on post-traumatic stress disorder (PTSD) and its interactive effects with PTSD on serum lipids levels in adolescents. @*Methods@#PTSD was measured by PTSD Checklist-Civilian Version (PCL-C) in 699 adolescent survivors at 6 months after Wenchuan earthquake in China. A polymerase chain reaction and restriction fragment length polymorphism assay were utilized for TNF-RII rs1061622 genotyping followed by verification using DNA sequencing. Serum triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol were tested using routine methods. @*Results@#G (deoxyguanine) allele carriers had higher PCL-C scores than TT (deoxythymidine) homozygotes in female subjects. Female adolescents had higher PCL-C scores than male subjects in TT homozygotes. Predictors of PTSD prevalence and severity were different between G allele carriers and TT homozygotes. Subjects with PTSD had lower TG, TG/HDL-C, TC/HDL-C, and higher HDL-C than adolescents without PTSD in male G allele carriers. G allele carriers had higher TG/HDL-C and TC/HDL-C than TT homozygotes in male adolescents without PTSD, and lower TG and TG/HDL-C in male PTSD patients. G allele carriers had higher TG than TT homozygotes only in female adolescents without PTSD. @*Conclusion@#These results suggest reciprocal actions of TNF-RII rs1061622 with other factors on PTSD severity, interplays of TNF-RII rs1061622 with PTSD on serum lipid levels, and novel treatment strategies for PTSD and comorbidities of PTSD with hyperlipidemia among adolescents with different genetic backgrounds of TNF-RII rs1061622 after experiencing traumatic events.

Prescription and medication rules of traditional Chinese medicine for prevention and treatment of diabetic microangiopathy based on literature mining / 中国中药杂志

This study explored the prescription and medication rules of traditional Chinese medicine(TCM) in the prevention and treatment of diabetic microangiopathy based on literature mining. Relevant literature on TCM against diabetic microangiopathy was searched and prescriptions were collected. Microsoft Excel 2021 software was used to establish a prescription database, and an analysis was conducted on the frequency, properties, flavors, meridian tropism, and efficacy classifications of drugs. Association rule analysis, cluster analysis, and factor analysis were performed using SPSS Modeler 18.0 and SPSS Statistics 26.0 software. The characteristic active components and mechanisms of action of medium-high frequency drugs in the analysis of medication rules were explored through li-terature mining. A total of 1 327 prescriptions were included in this study, involving 411 drugs, with a total frequency reaching 19 154 times. The top five high-frequency drugs were Astragali Radix, Angelicae Sinensis Radix, Poria, Salviae Miltiorrhizae Radix et Rhizoma, and Rehmanniae Radix. The cold and warm drugs were used in combination. Drugs were mainly sweet, followed by bitter and pungent, and acted on the liver meridian. The majority of drugs were effective in tonifying deficiency, clearing heat, activating blood, and resolving stasis. Association rule analysis identified the highly supported drug pair of Astragali Radix-Angelicae Sinensis Radix and the highly confident drug combination of Poria-Alismatis Rhizoma-Corni Fructus. The strongest correlation was found among Astragali Radix, Angelicae Sinensis Radix, Poria, and Salviae Miltiorrhizae Radix et Rhizoma through the complex network analysis. Cluster analysis identified nine categories of drug combinations, while factor analysis identified 16 common factors. The analysis of active components in high-frequency drugs for the treatment of diabetic microangiopathy revealed that these effective components mainly exerted their effects by inhibiting oxidative stress and suppressing inflammatory reactions. The study found that the pathogenesis of diabetic microangiopathy was primarily characterized by deficiency in origin, with a combination of deficiency and excess. Deficiency was manifested as Qi deficiency and blood deficiency, while excess as phlegm-heat and blood stasis. The key organ involved in the pathological changes was the liver. The treatment mainly focused on supplementing Qi and nourishing blood, supplemented by clearing heat, coo-ling blood, activating blood, and dredging collaterals. Commonly used formulas included Danggui Buxue Decoction, Liuwei Dihuang Pills, Erzhi Pills, and Buyang Huanwu Decoction. The mechanisms of action of high-frequency drugs in the treatment of diabetic microangiopathy were often related to the inhibition of oxidative stress and suppression of inflammatory reactions. These findings can provide references for the clinical treatment of diabetic microangiopathy and the development of targeted drugs.

Is dorsal vagal complex the key nucleus of acupuncture regulation of gastric function？ / 中国针灸

Acupuncture has remarkable effects on treating functional gastrointestinal diseases, but its central mechanism is not clear. At present, the research has mainly focused on several central nuclei, such as the dorsal vagus complex (DVC), nucleus raphe magnus (NRM), locus coeruleus (LC), subnucleus reticularis dorsalis (SRD), hypothalamic paraventricular nucleus (PVN), cerebellar fastigial nucleus (FN), central amygdala (CeA), etc. It is not clear whether the nuclei are involved in acupuncture regulation of gastric function through certain interrelation. A further summary of related literature indicates that many brain regions or nuclei in the central nervous system are closely related to gastric function, such as DVC, NRM, parabrachial nuclei (PBN), LC, periaqueductal gray (PAG), cerebellum, PVN, arcuate nucleus (Arc), hippocampus, CeA, etc. Most of these nuclei have certain fiber connections with each other, in which DVC is the basic center, and other nuclei are directly or indirectly involved in the regulation of gastric function through DVC. Is DVC the key target in acupuncture regulation of gastric function? Does other nuclei have direct or indirect neural circuit with DVC to participate in the regulation of gastric function by acupuncture, such as the possibility of CeA-DVC neural loop in acupuncture regulating gastric function. Therefore, more advanced techniques such as photogenetics, chemical genetics should be introduced and the central mechanism of acupuncture on regulating gastric function with DVC as center, from the view of nerve loop, will become the focus of further research, which could explain the central integration mechanism of acupoint compatibility by modern neuroscience technology.

Research on Therapeutic Mechanism of Canhuang Tablets on Jaundiced Rats Induced by ANIT / 中国实验方剂学杂志

Objective:To explore the therapeutic mechanism of Canhuang tablets on the mRNA and protein expression of farnesoid X receptor (FXR), uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) and multidrug resistance associated protein 2 (MRP2) in the liver of jaundiced rats induced by α-naphthalene isothiocyanate (ANIT). Method:The rats were divided into normal group, model group, Canhuang tablets (CHP) group and ursodeoxycholic acid tablets (UDCA) group. The jaundice model was reproduced by ANIT. After the intervention of the corresponding drugs, the contents of total bilirubin (TBIL), total bile acid (TBA), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) in serum and the liver histopathology were examined to evaluate the therapeutic effect of CHP. The relative mRNA and protein expressions of FXR, UGT1A1 and MRP2 in rat liver tissues were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot. Result:CHP can significantly reduce the increase of TBIL, TBA, ALT, AST and ALP caused by ANIT in rat serum, and inhibit the liver pathological changes, which showed that the removing jaundice effect of CHP was better than UDCA. Compared with the normal group, ANIT significantly inhibited the mRNA levels of FXR, UGT1A1 and MRP2 in rat liver tissues after modeling (P<0.01). Compared with the model group, CHP and UDCA significantly increased the mRNA levels of target genes of each protein after intervention (P<0.01), and CHP was superior to UDCA in improving the mRNA level of bilirubin metabolizing enzyme UGT1A1 (P<0.01). In the aspect of affecting protein expression, compared with the normal group, ANIT modeling significantly increased the expression of FXR in rats (P<0.05). CHP intervention showed a tendency to promote the expression of FXR, while UDCA did not, but there was no significant difference between them. In the aspects of promoting bilirubin metabolism and bile excretion, the expressions of UGT1A1 and MRP2 were significantly decreased by ANIT modeling (P<0.01), while the expressions of UGT1A1 and MRP2 proteins were significantly increased after treatment of CHP (P<0.01). CHP was superior to UDCA in increasing the expression of bilirubin and bile acid efflux protein MRP2 (P<0.01). Conclusion:The jaundice abating mechanism of CHP is related to activating FXR mRNA expression in liver, promoting the mRNA and protein expression of bilirubin metabolizing enzyme UGT1A1 and bile acid transporter MRP2, improving liver metabolism of free bilirubin and promoting bile acid excretion from the liver, and alleviating cholestatic liver injury.

Variant analysis on steroid 5-reductase type 2 deficiency caused by a novel SRD5A2 mutation / 中国当代儿科杂志

This article reported the clinical characteristics and SRD5A2 gene mutation pattern of a child with steroid 5-α reductase type 2 deficiency. The 2-month-old boy showed hypospadias and short penis shortly after birth. DNA was extracted from the peripheral blood of the child and his parents. The endocrine disease-related genes were captured and sequenced by high-throughput sequencing technology, and the family DNA samples were verified by Sanger sequencing. The results showed that c.680G>A(p.R227Q) and c.608G>A(p.G203D) compound heterozygous mutations existed in the SRD5A2 gene of the child. The c.680G>A mutation inherited from his father, which was a known pathogenic mutation. The c.608G>A mutation originated from his mother, which was a novel mutation discovered in this study. These results provide molecular evidence for the etiological diagnosis of the child and genetic counseling for the family, as well as extend the mutation spectrum of SRD5A2 gene.

Hence, TCEs may be of potential therapeutic value for patients with prediabetes, as an adjuvant therapy along with other treatments. Although the evidence suggests that the intervention is effective for 6 months, the mechanism of TCEs on glycemic control, the minimum exercise dose and their safety remain to be further studied.

Whole body application of nerve growth factor promotes early healing of tibial shaft fracture and improves expression of bone morphogenetic protein-2 and vascular endothelial growth factor in rats / 中国组织工程研究

BACKGROUND: Fracture healing is a very complex, multi-stage physiological process with the coordinated participation of multiple cells. The influence of neurological factors on fracture healing has attracted increasing attention. Nerve growth factor is a bioactive complex protein that promotes cell growth. The mechanism of its role in promoting fracture healing is not clear. OBJECTIVE: To observe the effect of nerve growth factor on the healing of tibial fracture in rats and the mechanism. METHODS: Seventy-two male Sprague-Dawley rats were randomly divided into model group and treatment group. The model of tibial shaft closed fracture was established followed by intramedullary fixation. The treatment group was given intramuscular injection of nerve growth factor; the model group was given intramuscular injection of normal saline. The study was approved by the Experimental Animal Ethics Committee of Fujian Medical University on May 30, 2018, with approval No. FJYKDX-2018-035. RESULTS AND CONCLUSION: The callus volume in the treatment group was significantly higher than that in the model group at 2 and 4 weeks of intervention. At 6 weeks of intervention, the fracture line disappeared, the medullary cavity was recanalized, and the fracture in the treatment group healed earlier than that in the control group. Hematoxylin-eosin staining showed that the trabeculae grew densely and a large number of osteoblasts were observed in the treatment group at 2 and 4 weeks after intervention. The serum alkaline phosphatase level in the treatment group was significantly higher than that in the model group at 2 and 4 weeks of intervention. Immunohistochemical results showed that the positive expression of bone morphogenetic protein 2 and vascular endothelial growth factor in the callus of treatment group was significantly higher than that of model group at 2 and 4 weeks after intervention. The results of quantitative PCR showed that the mRNA expression of bone morphogenetic protein 2 and vascular endothelial growth factor in the treatment group was higher than that in the model group at 2 and 4 weeks after intervention. To conclude, the whole body application of nerve growth factor can enhance the osteogenesis of tibial fracture end and promote the early healing of tibial fracture in rats. At the same time, nerve growth factor can promote the expression of bone morphogenetic protein 2 and vascular endothelial growth factor, which shows certain regularity in different periods, and in turn induces the differentiation and proliferation of osteoblasts as well as formation and calcification of extracellular matrix to promote bone formation and bone healing.

Analysis of Serum Transcriptome Characteristics of Patients with Yin and Yang Syndromes of Acute Ischemic Stroke / 中国实验方剂学杂志

Objective:To obtain the regulatory relationship between genes by screening the differentially expressed long non-coding ribonucleic acid(lncRNA), microRNA(miRNA) and messenger RNA(mRNA) in serum of patients with Yin and Yang syndromes of acute ischemic stroke, and to discuss the material basis and biological mechanism of formation of Yin and Yang syndromes of acute ischemic stroke from the transcriptome level. Method:The microarray chips were adopted to detect expression of lncRNA, mRNA and miRNA in serum of ischemic stroke patients with Yin and Yang syndromes and non-stroke subjects(10 cases each). Differential expression profiles related to Yin and Yang syndromes were selected by conjoint analysis. Further, the obtained differential genes were subjected to antisense lncRNA and mRNA co-expression analysis, gene ontology(GO) and Kyoto encyclopedia of genes and genomes(KEGG) functional pathway analysis, and the intergenic regulatory relationship was obtained to predict the target genes of lncRNA. Partial differential genes in 40 patients(10 with Yang syndrome and 30 with Yin syndrome) were verified by real-time fluorescence quantitative polymerase chain reaction(Real-time PCR). Result:The expression of 227 lncRNA, 54 mRNA and 4 miRNA were closely related to Yang syndrome, 394 lncRNA and 206 mRNA were closely related to Yin syndrome. Antisense lncRNA RP11-647P12.1 and RP11-677M14.2 may regulate the expression of neuron-derived neurotrophic factor(NDNF) and neurogranin(NRGN) by up-regulating the expression level in Yang syndrome. The differential expression of mRNA between Yin syndrome and Yang syndrome was mainly related to neurotransmitter receptor activity regulation, endocrine hormone regulation, inflammatory response, renin-angiotensin system and other pathways. Conclusion:There are differences in the expression profiles of lncRNA, miRNA and mRNA between Yin syndrome and Yang syndrome in acute ischemic stroke, which may be regulated by multiple pathways, such as blood pressure regulation, adrenergic receptor regulation, renin-angiotensin system and γ-aminobutyric acid(GABA). The transcriptome characteristics provide scientific basis for studying the biological basis of Yin syndrome and Yang syndrome in acute ischemic stroke.

Wound transplant flap was survived, no obvious scar tissue formation, appearance was flat, skin color was a little deeper than normal skin, the overall effect was satisfactory.@*CONCLUSIONS@#Three-step sequential method has good curative effect for patients suffered from limb skin soft tissue defect with bone or tendon exposed wound and refused to repair the flap, and has advantage of simple operation, operation risk, less invasive.

Different mini skin flaps in repairing finger soft tissue with bone defect / 中国骨伤

OBJECTIVE@#To explore surgical methods and clinical effects of three different types of mini skin flap transplantation for repairing finger soft tissue with bone defect.@*METHODS@#Thirty-three patients with finger soft tissue or bone defect were treated from December 2014 to October 2016, including 24 males and 9 females aged from 21 to 52 years old with an average of (36.42±5.70) years old, and soft tissue defect area ranged from 1.3 cm×1.8 cm to 2.3 cm×4.2 cm. According to damage degree, nature and patients' options, 15 finger of 15 cases were adopted retrograde dorsal metacarpal artery perforators fascia flap, 10 fingers of 9 cases were treated with free foot artery descending branch wrist skin flap, 9 fingers of 9 cases were treated with free the second toe details phalanges compound flap. Survival rate, postoperative complications and finger function assessed by Dargan functional criteria at the latest follow up were observed.@*RESULTS@#All flaps were survived, both of donor site and recipient site were without deep infected. The donor site of one patient occurred necrotic, and the distal donor site of one patient occurred surface necrotic, then healed by active dressing change. All patients were followed up from 6 to 16 months with an average of(8.34±1.28) months. Two points of finger recognition were restored between 8 and 12 mm with an average of (8.84±0.43) mm, and the appearance, texture and sensory functions of skin flap were restored. No obvious complications were observed on the donor site. According to Dargan function evaluation of finger joints, 18 patients got excellent results, 14 moderate and 1 good.@*CONCLUSIONS@#Three kinds of mini skin flap could receive good results in repairing soft tissue of finger or bone defect. Reverse dorsal metacarpal artery perforator fascia flap is not necessary with anastomosing blood vessels and has advantages of safe, simple and high survival rate. Descending branch of superior cutaneous branch of free ulnar artery could cut multiple other perforator flaps simultaneously, and the scar is small and hidden. Dissociated the second toe combined metatarsal phalangeal flap could repair shape and function of finger to the maximum extent and donor site is hidden.

Role of hippocampus NMDAR subunits in electroacupuncture at "Zhongwan" (CV 12) and "Weishu" (BL 21) for gastric motility / 中国针灸

OBJECTIVE@#To observe the effects of electroacupuncture (EA) on gastric motility, protooncogene c-fos and hippocampus N-methyl-D-aspartate (NMDA) receptor subunits in rats with functional dyspepsia (FD), and to discuss the molecular mechanism of hippocampal in EA at "Zhongwan" (CV 12) and "Weishu" (BL 21) for gastric motility.@*METHODS@#Eighty-four Sprague Dawley (SD) rats were randomly divided into a normal group, a model group, a Zhongwan group, a Weishu group, an acupoint combination group and a non-acupoint group, 14 rats in each one. Except for the normal group, FD model were established by moderate tail-clipping infuriation method and irregular feeding. The rats in the Zhongwan group, Weishu group, acupoint combination group and non-acupoint group were treated with EA at corresponding acupoints, 20 min per treatment, once a day for 7 days. The rats in the normal group and the model group received no treatment; grabbing and fixation were applied in the model group. The stress transducer was used to record gastric motion waveforms; immunohistochemistry method was used to detect the expression of c-fos in hippocampus; Western blot method was used to detect the expression of NMDA receptor subunits NR1, NR2A and NR2B in hippocampus.@*RESULTS@#Compared with the normal group, the gastric motility range was decreased (0.05). Compared with the model group, the gastric motility range was increased, the expression of hippocampus c-fos and expression of hippocampus NR2A was increased but expressions of NR1 and NR2B were reduced in the Weishu group, Zhongwan group and acupoint combination group (0.05). Compared with the Zhongwan group and the Weishu group, the gastric motility range was increased, the expression of hippocampus c-fos and NR2A was increased but the expression of NR1 and NR2B was reducedin the acupoint combination group (0.05).@*CONCLUSION@#EA at "Zhongwan" (CV 12) and "Weishu" (BL 21) could increase gastric motility of FD rats, which is likely to be related with activating hippocampal neurons, upregulating the level of NR2A and downregulating NR1 and NR2B.

Epithelial defect repair in the auricle and auditory meatus by grafting with cultured adipose-derived mesenchymal stem cell aggregate-extracellular matrix / 中华医学杂志(英文版)

BACKGROUND@#Several patients experience persistent otorrhea after a flawless surgical procedure because of insufficient epithelial healing. Several efforts, such as autologous tissue allograft and xenograft, have been made to halt otorrhea. However, a stable technology to induce temporal epithelial repair is yet to be established. Therefore, this study aims to investigate whether implantation of seeding adipose-derived mesenchymal stem cell (ADMSC) aggregates on extracellular matrix (ECM; herein, ADMSC aggregate-ECM) into damaged skin wound promotes skin regeneration.@*METHODS@#ADMSC aggregate-ECM was prepared using a previously described procedure that isolated ADMSCs from rabbits and applied to the auricle and auditory meatus wound beds of New Zealand white rabbits. Wound healing was assessed by general observation and hematoxylin and eosin (H&E) staining. Secretion of growth factor of the tissue was evaluated by western blotting. Two other groups, namely, ECM and control, were used. Comparisons of three groups were conducted by one-way analysis of variance analysis.@*RESULTS@#ADMSCs adhered tightly to the ECM and quickly formed cell sheets. At 2 weeks, general observation and H&E staining indicated that the wound healing rates in the ADMSC aggregate-ECM (69.02 ± 6.36%) and ECM (59.32 ± 4.10%) groups were higher than that in the control group (43.74 ± 12.15%; P = 0.005, P < 0.001, respectively) in ear auricle excisional wounds. At 7 weeks, The scar elevation index was evidently reduced in the ADMSC aggregate-ECM (2.08 ± 0.87) and ECM (2.31 ± 0.33) groups compared with the control group (4.06 ± 0.45; P < 0.001, P < 0.001, respectively). In addition, the scar elevation index of the ADMSC aggregate-ECM group reached the lowest rate 4 weeks in advance. In auditory meatus excisional wounds, the ADMSC aggregate-ECM group had the largest range of normal skin-like structure at 4 weeks. The ADMSC aggregate-ECM and ECM groups secreted increased amounts of growth factors that contributed to skin regeneration at weeks 1 and 2, respectively.@*CONCLUSIONS@#ADMSC aggregate-ECM and ECM are effective repair materials for wound healing, especially ADMSC aggregate-ECM. This approach will provide a meaningful experimental basis for mastoid epithelium repair in subsequent clinical trials.

Famous veteran traditional Chinese medicine doctors' medication rules in treating spermatorrhea / 中国中药杂志

To explore famous veteran traditional Chinese medicine( TCM) doctors' medication rules in treating spermatorrhea based on the medical cases about spermatorrhea collected from Hundred TCM Clinical Doctors of Hundred Years in China and Proven Cases and National Medical Master Test Case. Researchers extracted such data as medicinal and therapies from these cases according to the inclusion and exclusion criteria. Then,Excle 2010,SPSS Clementine 12. 0 and SPSS 22. 0 were adopted respectively for frequency analysis,association rules analysis,cluster analysis and factor analysis. Cluster analysis was carried out by Ochiai algorithm of binary variable data,one of the systematic clustering methods. And principal component analysis was used for factor analysis. Finally,27 medical cases and 41 prescriptions were included in total. The frequency analysis showed that the most common therapy was the astringent therapy( n = 28),which was followed by the tonifying method,tranquilizing method,heat-clearing method,damp-dispelling method and Qiregulating method. The top three kinds of high-frequency traditional Chinese medicines were Poria,Ostreae Concha and Dioscoreae Rhizoma. The association rules analysis found out 11 association rules of medicine pairs,23 association rules of medicine combinations of the three kinds of herbs and 6 association rules of medicine combinations of five kinds of herbs. Among them,the representatives were Rubi Fructus→Fossilia Ossis Mastodi,Rehmanniae Radix Praeparata + Corni Fructus→Dioscoreae Rhizoma,and Pinelliae Rhizoma→Citri Reticulatae Pericarpium,which showed the therapeutic characteristics of astringing,tonifying the kidney and replenishing essence,fortifying the spleen and dispelling dampness. Moreover,7 medicine groups with relevance were extracted from the tree map generated by cluster analysis,including " Phellodendri Chinensis Cortex and Anemarrhenae Rhizoma" and " Angelicae Sinensis Radix,Rehmanniae Radix,Bupleuri Radix and Glycyrrhizae Radix et Rhizoma",which demonstrated the effects of nourishing Yin and purging fire,tonifying and soothing the liver. Besides,totally 12 common factors were obtained according to factor analysis,including 14 drug combinations,like " Amomi Fructus,Anemarrhenae Rhizoma and Phellodendri Chinensis Cortex" and " Nelumbinis Stamen,Moutan Cortex,Poria and Scrophulariae Radix",which indicated the compatibility characteristics of tonifying the spleen and purging fire,dispelling dampness and clearing heat. In conclusion,data mining techniques( including frequency analysis,association rules analysis,cluster analysis and factor analysis) were used to comprehensively analyze the famous veteran TCM doctors' medication rules in treating spermatorrhea,which was helpful for guiding the clinical practice of treating spermatorrhea in TCM.
