Association of interpregnancy interval and risk of adverse pregnancy outcomes in woman by different previous gestational ages / 中华医学杂志(英文版)

BACKGROUND@#With an increasing proportion of multiparas, proper interpregnancy intervals (IPIs) are urgently needed. However, the association between IPIs and adverse perinatal outcomes has always been debated. This study aimed to explore the association between IPIs and adverse outcomes in different fertility policy periods and for different previous gestational ages.@*METHODS@#We used individual data from China's National Maternal Near Miss Surveillance System between 2014 and 2019. Multivariable Poisson models with restricted cubic splines were used. Each adverse outcome was analyzed separately in the overall model and stratified models. The stratified models included different categories of fertility policy periods (2014-2015, 2016-2017, and 2018-2019) and infant gestational age in previous pregnancy (<28 weeks, 28-36 weeks, and ≥37 weeks).@*RESULTS@#There were 781,731 pregnancies enrolled in this study. A short IPI (≤6 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.63 [1.55, 1.71] for vaginal delivery [VD] and 1.10 [1.03, 1.19] for cesarean section [CS]), low Apgar scores and small for gestational age (SGA), and a decreased risk of diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. A long IPI (≥60 months) was associated with an increased risk of preterm birth (OR [95% CI]: 1.18 [1.11, 1.26] for VD and 1.39 [1.32, 1.47] for CS), placenta previa, postpartum hemorrhage, diabetes mellitus in pregnancy, preeclampsia or eclampsia, and gestational hypertension. Fertility policy changes had little effect on the association of IPIs and adverse maternal and neonatal outcomes. The estimated risk of preterm birth, low Apgar scores, SGA, diabetes mellitus in pregnancy, and gestational hypertension was more profound among women with previous term births than among those with preterm births or pregnancy loss.@*CONCLUSION@#For pregnant women with shorter or longer IPIs, more targeted health care measures during pregnancy should be formulated according to infant gestational age in previous pregnancy.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine （Part 8）： Quality Evaluation with AGREE Ⅱ and RIGHT / 中医杂志

ObjectiveTo evaluate the methodological and reporting quality of clinical practice guidelines for Chinese patent medicine （CPM） with internationally recognized tools the appraisal of guidelines for research and evaluation （AGEREE） Ⅱ and reporting items for practice guidelines in healthcare （RIGHT）， thereby providing refe-rence for the clinical application and future development of CPM guidelines. MethodsDatabases including CNKI， VIP， Wanfang and Sinomed were searched for CPM guidelines， as well as medlive.cn， websites of China Association of Chinese Medicine and Chinese Medical Association， and reference lists of the included papers. The quality of the guidelines was evaluated using the AGREE Ⅱand RIGHT tools， and consistency tests were performed using Interclass Correlation Coefficient， and descriptive analysis and chi-square test were used to analyze the reporting rate for each domain and the average score for each item. ResultsFinally， 140 CPM guidelines were included， of which 51 were disease-oriented and 89 were drug-oriented， all of which were issued by China. For 51 disease-oriented CPM guidelines， the highest average score of all six AGREE Ⅱ domains was 73.32% for clarity， and the lowest was 26.80% for application； for 89 drug-oriented CPM guidelines， the highest average score was 55.62% for scope and purpose， and the lowest was 31.32% for rigour of development. In terms of the seven domains of the RIGHT checklist， the highest reporting rate was 68.26% for background， and lowest was 27.45% for other areas regarding the disease-oriented CPM guidelines； the highest reporting rate was 61.31% for background， and the lowest was 4.49% for other areas regarding drug-oriented CPM guidelines. The average reporting rate was higher for disease-oriented than drug-oriented CPM guidelines in three domains of AGREE Ⅱ （rigour of development， clarity of presentation， editorial independence）， as well as four domains of RIGHT checklist （basic information， evidence， funding and declaration and management of interests， and other areas）. ConclusionThe overall methodology and reporting quality of the current CPM guidelines still need to be improved. It is recommended that future guideline development teams should strictly refer to the AGREE Ⅱ and RIGHT checklist， and take into account of the characteristics of CPM guidelines and relevant methodo-logical suggestions in the development and reporting of CPM guidelines， thereby guiding the clinical use of CPM in a better way.

Population pharmacokinetics of mycophenolic acid in pediatric patients with primary IgA nephropathy / 中国药房

OBJECTIVE To develop a population pharmacokinetic （PPK） model for mycophenolate mofetil active metabolite mycophenolic acid （MPA） in children with primary IgA nephropathy， explore the factors affecting the pharmacokinetic parameters of MPA， and provide a basis for clinical individualized therapy. METHODS Retrospective collection was conducted on 636 concentrations and clinical data from 47 pediatric patients with primary IgA nephropathy. PPK analysis was carried out by using the nonlinear mixed-effects model； the covariates were tested with a stepwise method. Goodness-of-fit plots， Bootstrap and visual predictive check were employed to evaluate the final model. RESULTS The pharmacokinetics of MPA in children with IgA nephropathy in vivo conformed to the first-order absorption and elimination two-compartment model （objective function value of 3 276.31）. Covariate analysis suggested that body weight and albumin （ALB） levels were significant influencing factors on apparent clearance rate and apparent distribution volume. The typical values of PPK parameters of MPA in the final model were as follows： the central room had a distributed volume of 5.79 L， the clearance rate was 4.06 L/h， the volume of peripheral ventricular distribution was 430.93 L， the clearance rate between compartments was 15.40 L/h， the oral absorption rate constant was 1.29 h－1. After verification， most of the predicted corrected observed concentration points were within the 90% confidence interval of the predicted corrected simulated concentration， indicating that the MPA final model had good predictive performance. CONCLUSIONS The PPK model of MPA in children with primary IgA nephropathy is established in this study， identifying body weight and ALB levels are significant factors affecting MPA metabolism.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 4）： Evidence Retrieval and Evaluation / 中医杂志

The retrieval and evaluation of evidence is the basis for the development of clinical practice guidelines for Chinese patent medicine. As traditional Chinese medicine has a different development trajectory and utilization characteristics from modern medicine， there is certain differences in terms of evidence composition， retrieval and integration.This paper discussed multi-source body of evidence on Chinese patent medicine based on modern evidence-based medicine and ancient medical literature， and summarized the retrieval strategy as well as the possible problems and solving methods. For different types of evidence on Chinese patent medicine， the corresponding evaluation tools have been recommended， and the order to integrate the evidence based on the quality of the evidence from high to low is suggested. Finally， a multi-source based evidence retrieval-evaluation-integration scheme for Chinese patent medicine has been formed， which will provide a methodological reference for practitioners in the development of clinical practice guidelines for Chinese patent medicine.

Methodology for the Development of Clinical Practice Guidelines for Chinese Patent Medicine（Part 3）： Identification of Clinical Questions / 中医杂志

The identification of clinical questions for clinical practice guidelines of Chinese patent medicine （CPM） is important for subsequent evidence retrieval， evaluation of evidence quality， formation of recommendations. This paper described a methodological proposal for the identification of clinical questions for CPM guidelines to highlight the characteristics of Chinese patent medicine and reflect its effect in specific stage of the disease. Considering four aspects， namely， the drug of Chinese patent medicine （D）， the specific disease stage （S）， comparison （C）， and specific outcome （O）， DSCO framework has been proposed to formulate the clinical questions. Multi-source information through scientific research， policy or standard documents， and clinical data are suggested for collecting clinical questions， and clear selection criteria should be set to finalize the clinical questions to be addressed by the guideline. In addition， the above process needs to be transparently and publicly reported in order to ensure the clarity and completeness of the guidelines.

Signal mining and analysis of adverse events of oseltamivir，zanamivir and baloxavir marboxil / 中国药房

OBJECTIVE To provide reference for safe drug use in clinic by mining the adverse drug events （ADE） of 3 kinds of anti-influenza A virus drugs （oseltamivir， zanamivir， baloxavir marboxil）. METHODS The ADE data of oseltamivir， zanamivir and baloxavir marboxil were collected from the FDA adverse event reporting system （FAERS） between the first quarter in 2004 and the third quarter in 2022， and mined by using reporting odds ratio （ROR） method. The designated medical events （DME） were estimated. The system organ class （SOC） in the Medical Dictionary for Regulatory Activities （MedDRA， version 25.0） was used for the classification and statistics of drug ADE terminology. RESULTS A total of 12 636， 1 749 and 1 283 ADE reports were retrieved for oseltamivir， zanamivir and baloxavir marboxil， involving 26， 16 and 17 SOCs， respectively. Oseltamivir was strongly associated with sleep terror， abnormal behavior， hallucination and delirium. Zanamivir was implicated in abnormal behavior， delirium， incoherence， and altered state of consciousness with prominent signal intensity. Baloxavir marboxil was strongly associated with ischemic colitis， hemorrhagic cystitis， erythema multiforme and melaena. Erythema multiform was detected in the DME of three drugs with strong signals. CONCLUSIONS When clinically administering the three drugs， it is crucial to pay close attention to both common adverse reactions and those ADEs that are not explicitly mentioned in the drug instructions. For oseltamivir， clinicians should exercise caution due to the potential risk of acute kidney injury and fulminant hepatitis， necessitating regular monitoring of the patient’s liver and kidney function. When prescribing zanamivir， caution should be exercised due to ADEs related to the respiratory system， including acute respiratory distress syndrome and respiratory failure， necessitating close monitoring of the patient’s respiratory status. Similarly， for baloxavir marboxil， clinicians should be vigilant for potential ADEs such as erythema multiforme and rhabdomyolysis.

MethodThe clinical information form of CIS complicated with OSAHS formulated by the research group was used for syndrome survey， and the four-examination information of 300 patients with CIS complicated with OSAHS was collected. The four-examination information of patients was analyzed by latent structure method and comprehensive cluster analysis， and the common syndrome elements of CIS complicated with OSAHS were extracted by combining the TCM basic theory and clinical experience. On this basis， the characteristics of TCM syndromes and the syndrome types in line with reality were summarized. ResultThe top five syndrome elements in patients with CIS and OSAHS are sleep snoring， open mouth breathing， physical obesity， night awakening and dizziness. The top five tongue and pulse manifestations are enlarged tongue， slippery pulse， slippery coating， thick and white coating and purple tongue. The disease locations are the lung， spleen， stomach， kidney， liver and brain. The nature of disease includes deficiency， depression， blood stasis， phlegm， dampness and fire. The clinical syndrome types include the syndrome of stagnation of phlegm and dampness， syndrome of phlegm-dampness blocking the mind， syndrome of spleen deficiency with dampness， syndrome of Yin deficiency leading to fire hyperactivity， syndrome of Qi depression blocking collaterals， syndrome of liver depression and blood stasis， syndrome of Qi deficiency with dampness， and syndrome of Yang deficiency induced water retention. ConclusionIn addition to the common phlegm-， dampness- and blood stasis-related syndromes in patients with CIS and OSAHS， there are also depression- and deficiency-related syndromes. The main etiology and pathogenesis is the disturbance of Qi movement. In clinical practice， attention should be paid to the specific situation of individual patients to differentiate between deficiency and excess， and the treatment should be performed by the method of soothing and reinforcing， or unblocking and clearing， or both.

Influence of personality traits， resilience and coping style on the efficacy of sertraline treatment in female adolescents with first-episode depressive disorder / 四川精神卫生

BackgroundDepressive disorders are prevalence among adolescents， with a higher incidence in females compared to males， often accompanied by more severe depressive symptoms. Sertraline is commonly prescribed for adolescent depressive disorder， however， its efficacy is only evident in certain patients. Currently， there is limited research on predicting the therapeutic efficacy of sertraline in female adolescents with depressive disorder. ObjectiveTo explore the relationship between personality traits， psychological resilience， coping style and the clinical efficacy of sertraline treatment in female adolescents with first-episode depressive disorder， in order to provide references for the treatment of this population. MethodsA total of 112 female adolescent patients with first-episode depressive disorder， meeting the diagnostic criteria of the International Classification of Diseases （tenth edition） （ICD-10）， and undergoing a 4-week treatment regimen with sertraline， were selected from the Second People's Hospital of Guizhou Province from February 2019 to January 2021.General demographic questionnaire， NEO Five-Factor Inventory （NEO-FFI）， Resilience Scale for Chinese Adolescents （RSCA）， Coping Style Scale for Middle School Students （CSSMSS）， Hamilton Anxiety Scale （HAMA） and Hamilton Depression Scale-17 item （HAMD-17） were used for assessment. Logistic regression analysis was used to investigate the factors influencing the clinical efficacy of sertraline in the treatment of female adolescents with first-episode depressive disorder. ResultsNeuroticism （β=-0.115， 95% CI： 0.807~0.984） could negatively predicted the therapeutic efficacy of sertraline in female adolescents with first-episode depressive disorder， whereas agreeableness （β=0.129， 95% CI： 1.025~1.264） and RSCA score （β=0.062， 95% CI： 1.004~1.128） could positively predict its therapeutic efficacy. ConclusionHigh neuroticism， low agreeableness and low psychological resilience may be the risk factors for the poor therapeutic effect of sertraline in the treatment of female adolescents with first-episode depressive disorder. ［Funded by 2019 Guiyang Science and Technology Program （number， Zhuke Contract ［2019］9-3-1）］

Genetic analysis of a Chinese pedigree with an allele dropout at the HLA-B locus / 中华医学遗传学杂志

OBJECTIVE@#To delineate a deletional mutation of the HLA-B gene in a Chinese pedigree.@*METHODS@#A female patient with acute myeloid leukemia who had visited Liuzhou People's Hospital in April 2022 was selected as the study subject. Routine human leukocyte antigen (HLA) was determined by using PCR-sequence specific oligonucleotide polymorphism (PCR-SSOP) and PCR-sequence-based typing (PCR-SBT) methods. Next generation sequencing (NGS) was used to validate the candidate variant in the HLA-B gene.@*RESULTS@#The PCR-SBT and SSOP results for the HLA-B locus were inconsistent for the patient and her daughter. The SSOP results of the two individuals were HLA-B*35:01, 40:02 and HLA-B*35:01, 40:01, respectively. However, the PCR-SBT results has indicated a mismatch with the nearest HLA-B*35:01 at exon 4. NGS results showed that the HLA-B*35:01 had a 9 bp deletion in the intron 5. The patient's husband was HLA-B*40:01, 58:01, which was normal.@*CONCLUSION@#The variant in intron 5 of the HLA-B gene in this pedigree has mapped to a primer-binding region for the SBT reagent, which has affected the accuracy of PCR-SBT results.

The postoperative pathology met the Sedlis standard. All patients were divided into RT alone group (100 cases) and CRT group (110 cases) according to the different adjuvant treatment regimens; and the efficacy and adverse reactions of both groups were also analyzed.Results:The 3-year progression-free survival (PFS) rate was 82.8%, 81.5%, respectively in RT alone group and CRT group ; 5-year PFS rate was 80.6%, 77.4%, respectively in RT alone group and CRT group; and there were no statistically significant differences in the PFS of both groups ( χ2 = 0.29, P = 0.591). The 3-year overall survival (OS) rate was 88.5%, 86.7%, respectively in RT alone group and CRT group; 5-year OS rate was 86.4%,82.6%, respectively in RT alone group and CRT group; and there were no statistically significant differences in the OS of both groups ( χ2 = 0.59, P = 0.443). The local recurrence rate was 8.0% (8/100) and 9.1% (10/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 0.08, P = 0.778); the distant metastasis rate was 11.0% (11/100) and 12.7% (14/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 0.15, P = 0.699); the incidence of bone marrow suppression was 42.0% (42 /100) and 61.8% (68/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 8.25, P < 0.01). The incidence of gastrointestinal reactions was 23.0% (23/100) and 77.3% (85/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 49.94, P < 0.01);the incidence of radiation cystitis was 3.0% (3/100) and 3.6% (4/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 0.06, P = 0.798). The incidence of radiation proctitis was 5.0 %(5/100) and 4.5% (5/110), respectively in RT alone group and CRT group, and the difference was statistically significant ( χ2 = 0.02, P = 0.877). Conclusions:For cervical cancer patients with intermediate-risk factors, CRT shows no survival benefit and increases the incidence of adverse reactions compared with RT alone.

miRNA-3653-3p reduces the proliferation and invasion ability of endometrial cancer cells by inhibiting PLAC8-Wnt-β-catenin signaling pathway / 肿瘤研究与临床

Objective:To investigate the effect of miRNA-3653-3p (miR-3653-3p) on the proliferation and invasion ability of endometrial cancer cells and its related mechanisms.Methods:The data of 356 endometrial cancer patients were downloaded from the OncoLnc database (http://www.oncolnc.org, updated version 2020), and the Kaplan-Meier method was used to analyze the relationship between the expression level of miR-3653-3p and the overall survival of endometrial cancer patients. The miRGator database (https://bio.tools/mirgator_v2.0, updated version 2019) was used to predict the target gene binding to miR-3653-3p. Human endometrial cancer cell lines AN3CA, HEC-1A, HEC-1B, Ishikawa and human normal endometrial epithelial cell line ESC were selected, and the relative expression level of miR-3653-3p was detected by using quantitative real-time fluorescent polymerase chain reaction (qRT-PCR). The cell line with the lowest expression of miR-3653-3p was selected as the research object, which was divided into the negative control group and miR-3653-3p group, and transfected with the control empty vector plasmid and miR-3653-3p overexpression plasmid. CCK-8 method was used to detect the proliferation ability of cells, Transwell method was used to detect the invasion ability of cells, and qRT-PCR and Western blot were used to detect the expression of miR-3653-3p target gene. The effect of miR-3653-3p on the related protein expression of Wnt- β-catenin signaling pathway was detected by using Western blot.Results:Data analysis in the OncoLnc database showed that compared with endometrial cancer patients with low miR-3653-3p expression, patients with high miR-3653-3p expression had better overall survival ( P < 0.01). Compared with human normal endometrial epithelial ESC, the expression levels of miR-3653-3p in endometrial cancer cell lines AN3CA, HEC-1A, HEC-1B, and Ishikawa were all decreased (all P < 0.05), and the relative expression level of miR-3653-3p was the lowest in HEC-1A cells, and HEC-1A cells were selected for subsequent experiments. The result of CCK-8 showed that compared with the negative control group, the ability of HEC-1A cells in the miR-3653-3p group decreased on the 2nd, 3rd, 4th, and 5th days (all P < 0.05). The result of the Transwell chamber invasion test showed that the number of HEC-1A cell invasion after culturing for 26 h in the negative control group and the miR-3653-3p group was (80±11) and (21±4), respectively, and the difference was statistically significant ( t = 5.18, P < 0.01); compared with the negative control group, the number of cell invasion in the miR-3653-3p group decreased. The miRGator database was used to predict that the target gene of miR-3653-3p might be placenta-specific protein 8 (PLAC8). The relative expression levels of PLAC8 mRNA in HEC-1A cells in the negative control group and miR-3653-3p group were (6.26±0.83) and (0.97±0.31), respectively, and the difference was statistically significant ( t = 6.00, P < 0.01); the relative expression level of PLAC8 mRNA in the miR-3653-3p group was lower than that in the negative control group. Compared with the negative control group, the PLAC8 protein of HEC-1A cells decreased, and the expression of Wnt-β-catenin signaling pathway related proteins β-catenin, transforming growth factor β (TGF-β), GSK-3β, and Rac1 decreased in the miR-3653-3p group. Conclusions:miR-3653-3p may inhibit the proliferation and invasion of endometrial cancer cells by regulating the PLAC8-Wnt-β-catenin signaling pathway.

Objective:To observe the effects of sparrow-pecking moxibustion at Shenque(CV8)and Guanyuan(CV4)on the writhing reaction and score,the temperature and blood flow perfusion of moxibustion point area and uterus,the serum levels of arginine vasopressin(AVP),prostaglandin(PG)F2α,and thromboxane(TX)B2 in rats with primary dysmenorrhea(PD)due to cold-dampness stagnation,and to explore the possible mechanism of sparrow-pecking moxibustion in treating PD.Methods:Thirty-two healthy non-pregnant female Wistar rats were randomly divided into a normal group,a model group,an ibuprofen group,and a sparrow-pecking moxibustion group,with 8 rats in each group.Except for the normal group,the other three groups were subjected to modeling with cold water bath combined with estradiol benzoate and oxytocin injection.Rats in the sparrow-pecking moxibustion group were treated with sparrow-pecking moxibustion at Shenque(CV8)and Guanyuan(CV4)on the 8th day of modeling,30 min/time,once a day for 3 d;those in the ibuprofen group were treated with 0.8 mL ibuprofen solution(a specification of 125 mg in 10 mL)on the 8th day of modeling,once a day for 3 d;those in the normal group and the model group were given 0.8 mL normal saline,once a day for 3 d.On the 11th day,rats in each group were intraperitoneally injected with oxytocin(2 U/rat),and the writhing incubation period and writhing score in 20 min were observed;the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus in vivo were detected;the serum levels of AVP,PGF2α,and TXB2 were determined.Results:The writhing incubation period was significantly longer(P<0.01)and the writhing score was significantly lower(P<0.01)in the sparrow-pecking moxibustion group and the ibuprofen group than in the model group;compared with the ibuprofen group,the writhing incubation period was prolonged(P<0.01)and the writhing score was decreased(P<0.01)in the sparrow-pecking moxibustion group;compared with the normal group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly decreased,while the serum PGF2α,AVP,and TXB2 levels were significantly increased(P<0.01)in the model group;compared with the model group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly increased,and the serum levels of PGF2α,AVP,and TXB2 were significantly decreased in the ibuprofen group and the sparrow-pecking moxibustion group(P<0.05 or P<0.01);compared with the ibuprofen group,the temperature and the blood perfusion of Shenque(CV8),Guanyuan(CV4),and uterus were significantly increased(P<0.05),the serum AVP and TXB2 levels were significantly decreased(P<0.05),while the serum PGF2α level had no statistical difference in the sparrow-pecking moxibustion group(P>0.05).Conclusion:Sparrow-pecking moxibustion had a remarkable analgesic effect on the rats with PD due to cold-dampness stagnation,and the mechanism may be related to the increased temperature and blood perfusion of the moxibustion point area and uterus,as well as the decreased serum PGF2α,AVP,and TXB2 levels.

Effects of acupuncture at Houxi(SI3)and Huantiao(GB30)on NF-κB/iNOS/NO pathway in lumbar disc herniation model rats / 针灸推拿医学（英文版）

Objective:To observe the effects of acupuncture at Houxi(SI3)and Huantiao(GB30)on the expression levels of nuclear factor kappa B(NF-κB),inducible nitric oxide synthase(iNOS),and nitric oxide(NO)of NF-κB inflammatory signaling pathway in L5 spinal nerve root of lumbar disc herniation(LDH)model rats and explore the mechanism of acupuncture in LDH treatment.Methods:Forty specific-pathogen-free healthy male Sprague-Dawley rats were randomly divided into a sham operation group,a model group,acupuncture group 1,and acupuncture group 2,with 10 rats in each group.The non-compression nucleus protrusion model was made by puncturing L4-L5 spinous process space and injecting autologous nucleus suspension.Acupuncture at bilateral Shenshu(BL23),Dachangshu(BL25),and Weizhong(BL40)was carried out in acupuncture group 1,and acupuncture at bilateral Houxi(SI3)and Huantiao(GB30)in acupuncture group 2.All rats were treated with balanced reinforcing and reducing needling manipulations,and the needles were retained for 30 min/time with one episode of needling manipulation every 10 min,once a day,14 times in total.The threshold value of paw withdrawal pain was measured by a thermal stimulation pain instrument;the serum NF-κB,iNOS,and NO levels were measured by enzyme-linked immunosorbent assay.The pathomorphological changes of spinal nerve roots were observed by hematoxylin-eosin(HE)staining;quantitative reverse transcription polymerase chain reaction was used to detect iNOS mRNA expression in spinal nerve roots;the NF-κB and iNOS protein expression in spinal nerve roots was detected by the immunofluorescence method.Results:Compared with the sham operation group,the threshold of paw withdrawal pain in the model group was decreased,and the expression levels of serum NF-κB,iNOS,and NO were increased;HE staining showed many degenerated and dissolved Schwann cells in spinal nerve roots with vacuolar changes;meanwhile,the expression levels of NF-κB and iNOS proteins,and the iNOS mRNA in spinal nerve roots were increased.Compared with the model group,the paw withdrawal pain thresholds in acupuncture group 1 and acupuncture group 2 were increased,and the increase in acupuncture group 2 was greater(P<0.05);the expression levels of serum NF-κB,iNOS,and NO in acupuncture group 1 and acupuncture group 2 were decreased,especially in acupuncture group 2(P<0.01);the vacuolar changes of spinal nerve roots,and the degeneration and lysis of Schwann cells in acupuncture group 1 and acupuncture group 2 were decreased,which were more obvious in acupuncture group 2;the NF-κB and iNOS protein expression and the iNOS mRNA expression levels in spinal nerve roots of acupuncture group 1 and acupuncture group 2 were decreased,especially in acupuncture group 2(P<0.01).Conclusion:Acupuncture at Houxi(SI3)and Huantiao(GB30)can improve the morphology of spinal nerve roots,inhibit the NF-κB and iNOS protein expression levels in spinal nerve roots and the serum NO level,and relieve the pain caused by inflammation of spinal nerve roots,which may be one of the mechanisms of acupuncture in LDH treatment.
