Feasibility of a novel type of complex anterior cervical fixation by using Mimics software / 中国骨伤

OBJECTIVE@#To investigate the feasibility of mimics software in analyzing a new type of complex anterior cervical fixation -- anterior transpedicular screw fixation+zero notch internal fixation.@*METHODS@#From January 2021 to September 2022, 50 normal pedestrians who underwent cervical spine CT scanning were selected for C1-C7 segment scanning, including 27 males and 23 females, aged from 25 to 65 years old with an average of (46.0 ± 9.0) years old. The dicom format is exported and engraved into the CD, and use the mimics software to perform 3D reconstruction of each segment. A simulated screw is placed on the image according to the critical value of zero notch screw (head and tail angle 44°, internal angle 29°). The position of zero notch screw in each segment is observed to determine the feasibility of anterior transpedicular screw fixation plus zero notch internal fixation.@*RESULTS@#For the upper zero notch screws the three-dimensional images of the cervical spine across all 50 subjects within the C3-C7 segments demonstrated safe position, with no instances of intersection with ATPS. For the lower zero notch screw, in C3-C4 and C4-C5, 4 out of 50 subjects are in the safe position in the three-dimensional images of cervical vertebrae, and 46 cases could achieve secure screw placement when the maximum caudal angle is(32.3±1.9) ° and (36.1±2.2) °, respectively. In C5-C6 and C6-C7 segments, no lower zero notch screws intersected with ATPS, and all screws are in safe positions.@*CONCLUSION@#Lower cervical anterior pedicle screw fixation plus zero notch internal fixation can achieve successful nail placement through the selected entry point and position.

Effect of nerve growth factor on elderly degenerative knee osteoarthritis pain / 中国骨伤

OBJECTIVE@#To explore effect of nerve growth factor (NGF) antibody on knee osteoarthritis (KOA) pain model was evaluated by in vitro model.@*METHODS@#Thirty male SPF rats aged 28-week-old were divided into blank group (10 rats with anesthesia only). The other 20 rats were with monoiodoacetate (MIA) on the right knee joint to establish pain model of OA, and were randomly divided into control group (injected intraperitoneal injection of normal saline) and treatment group (injected anti-NGF) intraperitoneal after successful modeling, and 10 rats in each group. All rats were received retrograde injection of fluorogold (FG) into the right knee joint. Gait was assessed using catwalk gait analysis system before treatment, 1 and 2 weeks after treatment. Three weeks after treatment, right dorsal root ganglia (DRG) were excised on L4-L6 level, immunostained for calcitonin gene-related peptide (CGRP), and the number of DRGS was counted.@*RESULTS@#In terms of gait analysis using cat track system, duty cycle, swing speed and print area ratio in control and treatment group were significantly reduced compared with blank group (P<0.05). Compared with control group, duty cycle and swing speed of treatment group were significantly improved (P<0.05), and there was no significant difference in print area ratio between treatment group and blank group (P>0.05). The number of FG-labeled DRG neurons in control group was significantly higher than that in treatment group and blank group (P<0.05). The expression of CGRP in control group was up-regulated, and differences were statistically significant compared with treatment group (P<0.05).@*CONCLUSION@#Intraperitoneal injection of anti-NGF antibody inhibited gait injury and upregulation of CGRP in DRG neurons. The results suggest that anti-nerve growth factor therapy may be of value in treating knee pain. NGF may be an important target for the treatment of knee OA pain.

Comprehensive analysis of insulin products complex disulfide bonds structure by high resolution mass spectrum / 药学学报

The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.

ObjectiveTo establish an allele-specific polymerase chain reaction （PCR） method for identifying Scolopendra dispensing granules， so as to ensure the quality and therapeutic effects of Scolopendra and its preparations. MethodThe primer interval suitable for the PCR was selected based on the cytochrome c oxidase subunit 3（COX-3） gene sequence of Scolopendra， and the single nucleotide polymorphism （SNP） loci of Scolopendra and its adulterants were mined from the interval for the design of specific primers. The samples of Scolopendra and its adulterants were collected. The PCR system was established and optimized regarding the annealing temperature， cycles， Taq enzymes， DNA template amount， PCR instruments， and primer concentrations， and the specificity and applicability of this method were evaluated. ResultThe PCR system was composed of 12.5 μL 2×M5 PCR Mix， 0.4 μL forward primer （10 μmol·L-1）， 0.4 μL reverse primer （10 μmol·L-1）， 2.5 μL DNA template， and 9.2 μL sterile double distilled water. PCR parameters： Pre-denaturation at 94 ℃ for 3 min， 30 cycles （94 ℃ for 20 s， 62 ℃ for 20 s， 72 ℃ for 45 s）， and extension at 72 ℃ for 5 min. After PCR amplification with the system and parameters above， the electrophoresis revealed a bright band at about 135 bp for Scolopendra and no band for the adulterants. ConclusionThe established allele-specific PCR method can accurately identify the medicinal materials， decoction pieces， and standard decoction freeze-dried powder of Scolopendra， as well as the intermediates and final products of Scolopendra dispensing granules， which is of great significance for ensuring the quality and clinical efficacy of Scolopendra and its preparations.

Study on the potential allergen and mechanism of pseudo-allergic reactions induced by combined using of Reduning injection and penicillin G injection based on metabolomics and bioinformatics / 药学学报

Based on the strategy of metabolomics combined with bioinformatics, this study analyzed the potential allergens and mechanism of pseudo-allergic reactions (PARs) induced by the combined use of Reduning injection and penicillin G injection. All animal experiments and welfare are in accordance with the requirements of the First Affiliated Experimental Animal Ethics and Animal Welfare Committee of Henan University of Chinese Medicine (approval number: YFYDW2020002). Based on UPLC-Q-TOF/MS technology combined with UNIFI software, a total of 21 compounds were identified in Reduning and penicillin G mixed injection. Based on molecular docking technology, 10 potential allergens with strong binding activity to MrgprX2 agonist sites were further screened. Metabolomics analysis using UPLC-Q-TOF/MS technology revealed that 34 differential metabolites such as arachidonic acid, phosphatidylcholine, phosphatidylserine, prostaglandins, and leukotrienes were endogenous differential metabolites of PARs caused by combined use of Reduning injection and penicillin G injection. Through the analysis of the "potential allergen-target-endogenous differential metabolite" interaction network, the chlorogenic acids (such as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, and isochlorogenic acid A) and β-lactam allergens in the combination of the two may be mainly regulated by PLD1, PLA2G12A and CYP1A1. The three upstream signal target proteins mainly activate the arachidonic acid metabolic pathway, promote the degranulation of mast cells, release downstream endogenous inflammatory mediators, and induce PARs.

The mechanism of chlorogenic acid against neuropathic pain induced by cisplatin / 药学学报

This study aimed to investigate the analgesic effect of chlorogenic acid on cisplatin-induced neuropathic pain and explored the underlying molecular mechanisms. The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Xinxiang Central Hospital, in compliance with the Institutional Animal Care Guidelines. Von Frey hair and a radiant heat was employed to measure mechanical allodynia and thermal hyperalgesia; Western blot was used to examine transient receptor potential vanilloid type-1 (TRPV1) protein expression in the rat dorsal root ganglion (DRG); patch clamp was used to record TRPV1 currents in DRG neurons. The experimental results showed that chlorogenic acid could attenuate cisplatin-induce mechanical allodynia and thermal hyperalgesia in rats. The expression of TRPV1 protein in DRGs was increased in cisplatin-treated rats, while chlorogenic acid also could reverse cisplatin-induced the upregulation of TRPV1 protein. Forthermore, chlorogenic acid could attenuate cisplatin-mediated the upregulation of TRPV1 current density. These above results indicated that chlorogenic acid could alleviate cisplatin-induced pain hypersensitivity through inhibition of the expression and function of TRPV1 in rats.

So, adequate protection of children’s safety and rights is the key to ethical review. This paper analyzed the current status of drugs clinical trials for rare disease in children, including trial difficulties and guarantee system; explained the ethical principles that should be followed in clinical trials, such as the principle of informed consent and the principle of no harm; and discussed the path of protecting children’s safety and rights, so as to raise awareness and attention of the importance of ethical review of clinical trials.

Impact of assisted reproductive technology on birth weight discordance in twins / 中国当代儿科杂志

OBJECTIVES@#To explore the association between assisted reproductive technology (ART) and birth weight discordance in twins (BWDT).@*METHODS@#A retrospective analysis was conducted on twin infants born between January 2011 and December 2020 at the Third Affiliated Hospital of Guangzhou Medical University, with complete basic birth data. The impact of ART on the occurrence of BWDT was identified by the multivariate logistic regression analysis.@*RESULTS@#A total of 3 974 pairs of twins were included, with 1 431 conceived naturally and 2 543 through ART. Neonates in the ART group had higher birth weights than those in the naturally conceived group (P<0.001). The incidence of BWDT was lower in the ART group compared to the naturally conceived group (16.17% vs 21.09%, P<0.001). The multivariate logistic regression analysis, adjusting for confounding factors such as maternal age, parity, pre-pregnancy body mass index, gestational diabetes, hypothyroidism, gestational age, and chorionic properties, showed no significant difference in the risk of BWDT between the ART and naturally conceived groups (P>0.05).@*CONCLUSIONS@#ART is not associated with the risk of BWDT.

Association between vaccination and the risk of immunoglobulin A vasculitis in children / 中国当代儿科杂志

OBJECTIVES@#To study the effect of vaccination on the short-term risk of immunoglobulin A vasculitis (IgAV) in children.@*METHODS@#A retrospective analysis was conducted on the general data and the vaccination history within one year prior to onset in children with IgAV hospitalized in the Children's Hospital Affiliated to Zhengzhou University from November 2021 to January 2023. Vaccine exposure rates in the risk period (3 months prior to IgAV onset) and the control period were compared by autocontrol-case crossover analysis, and the odds ratio and 95% confidence interval (95%CI) were calculated. A sensitivity analysis for the one-month and two-month risk periods was conducted.@*RESULTS@#A total of 193 children with IgAV were included, with a median age of 7.0 years. Among the 193 children, 36 (18.7%) received at least one dose of the vaccine within 1 year prior to IgAV onset, and 14 (7.3%) received at least one dose of the vaccine during the 3-month risk period. Compared to the unvaccinated IgAV group, the vaccinated IgAV group had a significantly younger age of onset (P<0.05). There were no significant differences in the proportions of children with gastrointestinal involvement, renal involvement, and joint involvement between the two groups (P>0.05). The odds ratio for developing IgAV after receiving any type of vaccine within 3 months prior to IgAV onset was 2.08 (95%CI: 0.82-5.27, P>0.05). Further sensitivity analysis for the 1-month and 2-month risk periods demonstrated that the odds ratios for developing IgAV after receiving any type of vaccine were 2.74 (95%CI: 0.72-10.48, P>0.05) and 2.72 (95%CI: 0.95-7.77, P>0.05), respectively.@*CONCLUSIONS@#Vaccination dose not increase the risk of IgAV, nor does it exacerbate clinical symptoms in children with IgAV.

OBJECTIVE@#To investigate the effectiveness of finger reconstruction using nail flap anastomosing the nerve branch of the first toe nail bed.@*METHODS@#Between January 2016 and December 2022, 18 patients (18 fingers) with thumb or finger nail bed defects were admitted. There were 12 males and 6 females, with an average age of 32 years (range, 19-42 years). Four cases were finger tip tissue damage caused by machine compression, and 4 cases were distal tissue necrosis after finger replantation. There were 9 cases of thumb injury, 3 cases of index finger injury, 5 cases of middle finger injury, and 1 case of ring finger injury. There were 11 cases of distal nail damage and 7 cases of distal nail root (including nail root) damage. The time from injury to admission was 1-5 hours, with an average of 2 hours. After debridement and anti-infection treatment for 5-7 days, the wounds in size of 1 cm×1 cm to 4 cm×3 cm were reconstructed by using nail flaps anastomosing the nerve branches of the first toe nail bed. The size of the nail flaps ranged from 1.5 cm×1.5 cm to 4.5 cm×3.5 cm. The donor sites were repaired with the flaps in 16 cases and skin graft in 2 cases.@*RESULTS@#All nail flaps, flaps, and skin grafts survived after operation and the wounds healed by first intention. All patients were followed up 6-12 months (mean, 10 months). The nails of 18 cases were all grown, in which 16 cases had smooth nails with satisfactory appearances, 1 case had uneven nails, and 1 case had obvious scar hyperplasia around the suture opening. At 6 months after operation, the two-point discrimination of the skin flap was 4-8 mm (mean, 6 mm). Meanwhile, the skin grafts and flaps at the donor sites regained protective sensation, good abrasion resistance, and had no negative effect upon walking and wearing shoes.@*CONCLUSION@#The application of a nail flap that anastomoses the nerve branch of the first toe nail bed for finger reconstruction has minimal damage and can achieve good nail bed repair results.

The distribution differences and characteristics of eight major components(ferulic acid, caffeic acid, neochlorogenic acid, cryptochlorogenic acid, benzoyl oxypaeoniflorin, tracheloside, loganin, and paeoniflorin) in rat liver, lung, heart, spleen, and kidney tissues were determined after oral administration of the Liangxue Tuizi Mixture at a dose of 42 g·kg~(-1) in both normal physiological and HSP states at 0.5, 1, 2, 6, and 12 hours. The results showed that the distribution patterns of the eight components of Liangxue Tuizi Mixture in the tissues of normal and HSP model rats were different. The main component, paeoniflorin, in Moutan Cortex and Paeoniae Radix Alba had higher content in all tissues. The eight components were predominantly distributed in the liver, lung, and kidney tissues, followed by spleen and heart tissues.

Efficacy and safety of flurbiprofen cataplasms versus loxoprofen sodium cataplasms in knee osteoarthritis: a randomized controlled trial / 中华医学杂志(英文版)

BACKGROUND@#Clinical trial evidence is limited to identify better topical non-steroidal anti-inflammatory drugs (NSAIDs) for treating knee osteoarthritis (OA). We aimed to compare the clinical efficacy and safety of flurbiprofen cataplasms (FPC) with loxoprofen sodium cataplasms (LSC) in treating patients with knee OA.@*METHODS@#This is an open-label, non-inferiority randomized controlled trial conducted at Peking University Shougang Hospital. Overall, 250 patients with knee OA admitted from October 2021 to April 2022 were randomly assigned to FPC and LSC treatment groups in a 1:1 ratio. Both medications were administered to patients for 28 days. The primary outcome was the change of pain measured by visual analog scale (VAS) score from baseline to day 28 (range, 0-10 points; higher score indicates worse pain; non-inferiority margin: 1 point; superiority margin: 0 point). There were four secondary outcomes, including the extent of pain relief, the change trends of VAS scores, joint function scores measured by the Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and adverse events.@*RESULTS@#Among 250 randomized patients (One patient without complete baseline record in the flurbiprofen cataplasms was excluded; age, 62.8 ± 10.5 years; 61.4% [153/249] women), 234 (93.6%) finally completed the trial. In the intention-to-treat analysis, the decline of the VAS score for the 24-h most intense pain in the FPC group was non-inferior, and also superior to that in the LSC group (differences and 95% confidence interval, 0.414 (0.147-0.681); P <0.001 for non-inferiority; P = 0.001 for superiority). Similar results were observed of the VAS scores for the current pain and pain during exercise. WOMAC scores were also lower in the FPC group at week 4 (12.50 [8.00-22.50] vs . 16.00 [11.00-27.00], P = 0.010), mainly driven by the dimension of daily activity difficulty. In addition, the FPC group experienced a significantly lower incidence of adverse events (5.6% [7/124] vs . 33.6% [42/125], P <0.001), including irritation, rash and pain of the skin, and sticky hair uncovering pain.@*CONCLUSIONS@#This study suggested that FPC is superior to LSC for treating patients with knee OA in pain relief, joint function improvement, and safety profile.

OBJECTIVE@#To observe the effects of Xingnao Kaiqiao (regaining consciousness and opening orifices) acupuncture therapy on the expression of hypoxia-inducible factor 1α (HIF-1α) and Nod-like receptor protein 3 (NLRP3) in cerebral ischemia-reperfusion rats, and to explore the mechanism of acupuncture against cerebral ischemia-reperfusion injury.@*METHODS@#Seventy-two male SD rats were randomly divided into a sham-operation group, a model group, an acupuncture group and a non-point acupuncture group, with 18 rats in each one. Using modified Longa thread embolization method, the rat model of acute focal cerebral ischemia was prepared; and after 2 h ischemia, the reperfusion was performed to prepared the model of cerebral ischemia-reperfusion. Immediately after reperfusion, Xingnao Kaiqiao acupuncture method was applied to bilateral "Neiguan" (PC 6) and "Shuigou" (GV 26) in the acupuncture group, while in the non-point acupuncture group, acupuncture was delivered at non-points and all of the needles were retained for 30 min in these two groups. The samples were collected 24 h after reperfusion in the rats of each group. Zea-Longa neurological deficit score was used to evaluate the degree of cerebral neurological impairment, TTC staining was adopted to observe the volume percentage of cerebral infarction, HE staining was provided to observe the morphological changes of brain, and Western blot was applied for detecting the expression of HIF-1α and NLRP3 proteins in the cerebral cortex on the right side.@*RESULTS@#Compared with the sham-operation group, neurological deficit score and volume percentage of cerebral infarction were increased in the model group (P<0.01), and HIF-1α and NLRP3 protein expression was elevated (P<0.01). Compared with the model group, neurological deficit score and volume percentage of cerebral infarction were decreased (P<0.01), and HIF-1α and NLRP3 protein expression was lower (P<0.01) in the acupuncture group. There was no significant difference in above indexes in the non-point acupuncture group compared with the model group (P>0.05). Compared with the sham-operation group, the brain tissue of the rats in the model group and the non-point acupuncture group was loose and edema, and the nuclei were shriveled. The brain tissue morphology in the acupuncture group was similar to that of the sham-operation group.@*CONCLUSION@#Acupuncture can alleviate cerebral ischemia-reperfusion injury, and its mechanism may be related to the regulation of HIF-1α/NLRP3 signaling pathway to attenuate inflammatory response.

Environmental enrichment ameliorates anxiety and depression-like behaviors in paternally stressed offspring mice through upregulation of hippocampal LASP1 / 西安交通大学学报(医学版)

【Objective】 To explore the role of environmental enrichment (EE) in paternal stress-induced anxiety and depression-like behaviors in offspring and its potential mechanisms. 【Methods】 Male C57BL/6 mice (F0) were treated with unpredictable chronic mild stress (UCMS) and subsequently mated with normal females to obtain F1 offspring mice. The standard environment (SE) and enriched environment (EE) were administered to F1-UCMS offspring mice during their early life (3-5 weeks of age). Anxiety-like behaviors were detected by open field test (OFT) and elevated plus-maze test (EPM); depression-like behaviors were detected via forced swimming test (FST) and sucrose preference test (SPT) at the age of 8 weeks. The expressions of LIM and SH3 domain protein 1 (LASP1) in the hippocampus of adult F1 offspring mice were detected by Real-time fluorescence quantitative PCR (RT-qPCR) and Western blotting. 【Results】 Compared to F1 offspring of normal paternal (F1-Nor), F1 offspring mice of the stressed paternal (F1-UCMS) showed significantly anxiety-like behavior with reduced percentage of time spent in the central region of OFT and in the open arm of EPM (P<0.05); mice from the F1-UCMS group showed a significantly increased percentage of immobility in FST and a reduced percentage of sugar consumption in SPT (P<0.01), which demonstrated significant depression-like behaviors. Compared to the SE group, mice in the EE group had an increased percentage of time spent in the central region of the OFT [males: (7.44±0.75)% vs. (14.93±1.74)%, P<0.01; females: (8.89±1.06)% vs. (15.10±1.82)%, P<0.05] and an increased percentage of time in the open arm of EPM [males: (8.09±1.05)% vs. (14.15±1.88)%, P<0.05; females: (9.13±1.14)% vs. (14.04±1.37)%, P<0.05]. This indicated that EE ameliorated anxiety-like behavior in F1-UCMS mice with paternal stress. Compared to the SE group, mice in the EE group had an decreased percentage of immobility in FST [males: (58.63±4.51)% vs. (42.15±3.81)%, P<0.05; females: (57.96±4.19)% vs. (43.25±4.22)%, P<0.05] and an increased percentage of sugar consumption in SPT [males: (50.38±3.47)% vs. (70.39±3.12)%, P<0.01; females: (52.42±2.84)% vs. (69.99±3.55)%, P<0.01]. This indicated that EE ameliorated depression-like behavior in F1-UCMS mice with paternal stress. Hippocampal LASP1 expression was reduced in SE group compared to F1-Nor group (males: P<0.01; females: P<0.05), while LASP1 was increased in EE group compared to SE group (P<0.05) detected by RT-qPCR and Western blotting. 【Conclusion】 EE ameliorates paternal stress-induced anxiety and depression-like behaviors in F1-UCMS mice, and the mechanism may be associated with increased hippocampal LASP1 expression in F1-UCMS mice.
