ABSTRACT

OBJECTIVE@#To investigate the effect of bone cement containing recombinant human basic fibroblast growth factor (rhbFGF) and recombinant human bone morphogenetic protein-2 (rhBMP-2) in percutaneous kyphoplasty(PKP)treatment of osteoporotic vertebral compression fracture(OVCF).@*METHODS@#A total of 103 OVCF patients who underwent PKP from January 2018 to January 2021 were retrospectively analyzed, including 40 males and 63 females, aged from 61 to 78 years old with an average of (65.72±3.29) years old. The injury mechanism included slipping 33 patients, falling 42 patients, and lifting injury 28 patients. The patients were divided into three groups according to the filling of bone cement. Calcium phosphate consisted of 34 patients, aged(65.1±3.3) years old, 14 males and 20 females, who were filled with calcium phosphate bone cement. rhBMP-2 consisted of 34 patients, aged (64.8±3.2) years old, 12 males and 22 females, who were filled with bone cement containing rhBMP-2. And rhbFGF+rhBMP-2 consisted of 35 patients, aged (65.1±3.6) years old, 14 males and 21 females, who were filled with bone cement containing rhbFGF and rhBMP-2. Oswestry disability index (ODI), bone mineral density, anterior edge loss height, anterior edge compression rate of injured vertebra, visual analog scale (VAS) of pain, and the incidence of refracture were compared between groups.@*RESULTS@#All patients were followed for 12 months. Postoperative ODI and VAS score of the three groups decreased (P<0.001), while bone mineral density increased (P<0.001), anterior edge loss height, anterior edge compression rate of injured vertebra decreased first and then slowly increased (P<0.001). ODI and VAS of group calcium phosphate after 1 months, 6 months, 12 months were lower than that of rhBMP-2 and group rhbFGF+rhBMP-2(P<0.05), bone mineral density after 6 months, 12 months was higher than that of rhBMP-2 and group calcium phosphate(P<0.05), and anterior edge loss height, anterior edge compression rate of injured vertebra of group rhbFGF+rhBMP-2 after 6 months and 12 months were lower than that of group rhBMP-2 and group calcium phosphate(P<0.05). There was no statistical difference in the incidence of re-fracture among the three groups (P>0.05).@*CONCLUSION@#Bone cement containing rhbFGF and rhBMP-2 could more effectively increase bone mineral density in patients with OVCF, obtain satisfactory clinical and radiological effects after operation, and significantly improve clinical symptoms.

ABSTRACT

ObjectiveTo investigate the antidepressant effect of Sinisan (SNS) by regulating glycogen aynthase kinase-3β (GSK-3β)/tumor necrosis factor alpha-induced protein 3(A20)/CCAAT enhancer binding protein β(C/EBPβ) to inhibit the activation of microglia. MethodA total of 72 male C57/6J mice were randomly divided into the normal group, model group, fluoxetine group (5.0 mg·kg-1), low-dose Sinisan group (4.9 g·kg-1), medium-dose Sinisan group (9.8 g·kg-1), and high-dose Sinisan group (19.6 g·kg-1), with 12 mice in each group. After one week of adaptive feeding, chronic unpredictable mild stress (CUMS) was performed to establish the depression model. In the fifth week, drug treatment was conducted for four weeks. In the ninth week, behavioral tests were performed, including sucrose preference test (SPT), open field test (OPT), elevated plus maze (EPM) test, and forced swimming test (FST). Western blot was used to detect the expression levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), nitric oxide synthase (iNOS), GSK-3β, A20, and C/EBPβ in the cortex. The expression of M1-polarized ionized calcium-binding adapter molecule 1 (Iba1) and cluster of differentiation 68 (CD68) in microglia was detected by immunofluorescence. ResultAfter eight weeks of CUMS, compared with the normal group, the mice in the model group had a significantly reduced sucrose preference rate (P<0.01), and the activity in the central area of the OPT was significantly reduced (P<0.01). The activity in the open arm area of the EPM test was significantly reduced (P<0.05), and the immobility time of FST was increased (P<0.01). The expression levels of inflammatory proteins IL-1β, IL-6, and iNOS were increased (P<0.01), and the fluorescence co-localization index of Iba1 and CD68 was increased (P<0.05). The protein expression levels of GSK-3β and C/EBPβ were significantly increased (P<0.05, P<0.01). After four weeks of SNS intervention, compared with the model group, the mice in the SNS group had significantly increased sucrose preference rate (P<0.01), significantly increased activities in the central area and the open arm area in the OPT and the EPM test (P<0.05), and significantly reduced immobility time in the FST (P< 0.01). The protein expression levels of IL-1β, IL-6, and iNOS were significantly decreased (P<0.05), and the fluorescence co-localization index of Iba1 and CD68 was decreased in the high-dose SNS group (P<0.05). The protein expression levels of GSK-3β and C/EBPβ in the medium-dose and high-dose SNS groups were significantly decreased (P<0.01), and that of A20 was significantly increased (P<0.01). ConclusionThe antidepressant effect of SNS is related to the regulation of GSK-3β/A20/C/EBPβ protein expression and the inhibition of M1-type activation of microglia.

ABSTRACT

Objective To explore the pharmacokinetic changes of single dose of fentanyl in rats in a simulated high-altitude and contributing factors.Methods Thirty-six healthy female SD rats(6~8 weeks old,250±20 g)were randomly divided into high-altitude-acute-exposure group(group A),high-altitude-chronic-exposure group(group S)and control group(group C)through random number table,with 12 rats in each group.The group A and S were housed in a low-pressure chamber simulating the high altitude of 5000 m above sea level for 3 and 30 d respectively,and the group C was housed out of the chamber(at an altitude of 300 m).A single dose of fentanyl was administered through the femoral vein to 6 rats randomly selected from each group.Liquid chromatography tandem mass spectrometry(LC-MS/MS)was used to detect blood concentrations of fentanyl and WinNonlin 8.2 software was used to calculate the pharmacokinetic parameters,while blood samples were taken through the femoral artery before and in 1,2,4,8,15,30,60,120 and 180 min after administration.The remaining 6 rats were ultrasonographically assessed for portal vein internal diameter(PVD),peak flow velocity(PVV)and blood flow(PVF),and liver tissues were collected for CYP3A1 protein content assay.Results The blood drug concentrations of fentanyl in the group A and group S were significantly lower than those in the group C at 60,120,and 180 min(P=0.002,P<0.001,P= 0.001).Compared with the group C,the clearance rate(CL)of the group A was increased by 54.06%(P=0.021),and the mean residence time(MRTlast)was shortened by 24.21%(P=0.033);CL of the group S was increased by 50.10%(P=0.041),the area under the concentration-time curve(AUC0-t,AUC0-∞)and MRTlast were reduced by 18.92%(P=0.039),27.54%(P=0.018)and 33.61%(P= 0.004),respectively.PVD and PVF in the group S increased by 10.87%(P=0.006)and 42.50%(P= 0.006)when compared with the group C.The CYP3A1 protein content in the group A was 28.74%,which was higher than that in the group C(P=0.048).Conclusion Fentanyl is cleared significantly faster after a single dose in rats in simulated high-altitude,which may be related to the increased liver blood flow and increased CYP3A1 protein expression in liver.

ABSTRACT

Currently,human health due to corona virus disease 2019(COVID-19)pandemic has been seriously threatened.The coronavirus severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)spike(S)protein plays a crucial role in virus transmission and several S-based therapeutic approaches have been approved for the treatment of COVID-19.However,the efficacy is compromised by the SARS-CoV-2 evolvement and mutation.Here we report the SARS-CoV-2 S protein receptor-binding domain(RBD)inhibitor licorice-saponin A3(A3)could widely inhibit RBD of SARS-CoV-2 variants,including Beta,Delta,and Omicron BA.1,XBB and BQ1.1.Furthermore,A3 could potently inhibit SARS-CoV-2 Omicron virus in Vero E6 cells,with EC50 of 1.016 pM.The mechanism was related to binding with Y453 of RBD deter-mined by hydrogen-deuterium exchange mass spectrometry(HDX-MS)analysis combined with quan-tum mechanics/molecular mechanics(QM/MM)simulations.Interestingly,phosphoproteomics analysis and multi fluorescent immunohistochemistry(mIHC)respectively indicated that A3 also inhibits host inflammation by directly modulating the JNK and p38 mitogen-activated protein kinase(MAPK)path-ways and rebalancing the corresponding immune dysregulation.This work supports A3 as a promising broad-spectrum small molecule drug candidate for COVID-19.

ABSTRACT

A male infant, aged 6 days, was admitted to the hospital due to respiratory distress and systemic desquamative rash after birth. The infant presented with erythema and desquamative rash, respiratory failure, recurrent infections, chronic diarrhea, hypernatremic dehydration, and growth retardation. Comprehensive treatment, including anti-infection therapy, intravenous immunoglobulin administration, and skin care, resulted in improvement of the rash, but recurrent infections persisted. Second-generation sequencing revealed a homozygous mutation in the SPINK5 gene, consistent with the pathogenic variation of Netherton syndrome. The family opted for palliative care, and the infant died at the age of 2 months after discharge. This report documents a case of Netherton syndrome caused by the SPINK5 gene mutation in the neonatal period, and highlights multidisciplinary diagnosis and therapy for this condition.

ABSTRACT

【Objective】 To evaluate the clinical efficacy and safety of platelet-rich plasma(PRP) in acute achilles tendon injury by meta-analysis. 【Methods】 Literature on clinical randomized controlled trial of PRP in the treatment of acute achilles tendon injury from Wanfang database, CNKI, VIP database, The Chinese Biological Literature Database, The Chinese Clinical Trials Registry, PubMed, Embase, Cochrane and The US Clinical Trials Registry as of August 2023 were retrieved. The control group received conventional treatment for acute achilles tendon injury, while PRP treatment group received additional PRP treatment. The primary outcome measure was visual analogue pain scale, and the secondary outcome measures were the achilles tendon fracture score, maximum heel rise height, calf circumference and ankle range of motion. The quality of the literature was assessed using the Cochrane manual, and a meta-analysis of qualified literature was performed using RevMan 5.3 software. 【Results】 Seven articles were finally included, involving 421 patients with acute achilles tendon injury, including 212 patients in the PRP treatment group, and 209 patients in the conventional treatment group. The results of meta-analysis showed that there was no difference between the conventional treatment group and the PRP treatment group in terms of the visual analogue pain scale(SMD=-0.44, 95%CI: -0.94~0.06, P>0.05), calf circumference (MD=1.14, 95% CI: -1.56-3.84, P>0.05), ankle joint toe flexion range of motion (SMD=1.85, 95%CI: -1.38-5.09, P>0.05), ankle dorsiflexion range of motion(SMD=2.61, 95%CI: -0.95-6.17, P>0.05), achilles tendon fracture score (MD=-5.60, 95%CI: -15.36-4.16, P>0.05) and the maximum heel rise height (MD=-2.48, 95%CI: -5.30-0.33, P>0.05). And there was no difference in the incidence of adverse reactions between the two groups (X2=2. 455, P>0.05). 【Conclusion】 PRP injection for acute achilles tendon injury does not improve the biomechanical and clinical outcomes of patients, and the use of PRP does not increase the occurrence of adverse reactions.

ABSTRACT

Based on the UHPLC-Q-Exactive-MS metabonomics technology, the effect of Hippocampus kuda Bleeker on the life span of Drosophila melanogaster was studied, and the change rule of endogenous metabolites in the aging process of Drosophila melanogaster after the intervention of Hippocampus kuda Bleeker japonicus was explored to clarify the anti-aging mechanism of Hippocampus. The natural aging model of Drosophila melanogaster was used. Different doses of raw Hippocampus and fried Hippocampus were given to observe the effects on the life span, climbing ability, sexual activity, and antioxidant enzyme activity of Drosophila melanogaster. Based on UHPLC-Q-Exactive-MS metabolomics technology, the metabolic profile of the aging Drosophila melanogaster was analyzed using metabonomics technology to explore the mechanism of Hippocampus kuda Bleeker delaying the aging of Drosophila melanogaster. The results showed that raw Hippocampus and crispy Hippocampus (1, 4 mg·mL-1) could significantly prolong the average life span, median life span and maximum life span of male fruit flies, and significantly improve the climbing ability and sexual vitality of fruit flies. Catalase (CAT) and aldehyde content were increased, while malonaldehyde (MDA) content was decreased. Through metabonomics technology, it was identified that the Hippocampus can significantly recall 16 metabolites and participate in the biosynthesis of phenylalanine, tyrosine and tryptophan, starch and sucrose metabolism, tyrosine metabolism, cysteine and methionine metabolism, and histidine metabolism. The anti-aging mechanism is related to amino acid metabolism and sugar metabolism, which provides a substantial scientific basis for the development and utilization of Hippocampus and clarifying its role in senile diseases. The animal experiment of this study was approved by the Ethics Committee of Shanxi University (approval number: SXULL2021028).

ABSTRACT

Lilii Bulbus is a commonly used Chinese herbal medicine with both medicinal and edible values, while the market products usually has the problem of sulfur fumigation. Therefore, the quality and safety of Lilii Bulbus products deserve attention. In this study, ultra-high performance liquid chromatography-time of flight-tandem mass spectrometry(UPLC-Q-TOF-MS/MS) was combined with principal component analysis(PCA) and orthogonal partial least squares discriminant analysis(OPLS-DA) to analyze the differential components of Lilii Bulbus before and after sulfur fumigation. We identified ten markers generated after sulfur fumigation, summarized their mass fragmentation and transformation patterns, and verified the structures of phenylacrylic acid markers of sulfur fumigation. At the same time, the cytotoxicity of the aqueous extracts of Lilii Bulbus before and after sulfur fumigation was evaluated. The results showed that in the concentration range of 0-800 mg·L~(-1), the aqueous extract of Lilii Bulbus after sulfur fumigation had no significant effect on the viability of human liver LO2 cells, human renal proximal tubular HK-2 cells, and rat adrenal pheochromocytoma PC-12 cells. Moreover, the viability of the cells exposed to the aqueous extract of Lilii Bulbus before and after sulfur fumigation showed no significant difference. This study identified phenylacrylic acid and furostanol saponins as markers of sulfur-fumigated Lilii Bulbus for the first time, and made clear that proper sulfur fumigation of Lilii Bulbus would not produce cytotoxicity, providing a theoretical basis for the rapid identification and quality and safety control of sulfur-fumigated Lilii Bulbus.

ABSTRACT

OBJECTIVE@#The relationship between the distal screws and the wrist articular surface was assessed by the additional lateral oblique fluoroscopic view during the operation, and the dorsal tangential view of the wrist was used to observe whether the distal screw penetrated the dorsal cortex, so as to evaluate the clinical efficacy of the volar locking plate in the treatment of distal radius fractures.@*METHODS@#From January 2020 to June 2021, 45 cases of fresh distal radius fractures were treated using the volar Henry's approach, including 20 males and 25 females, aged from 32 to 75 years old with an average of (52.4±8.1) years old. During the operation, they were divided into 2 groups according to the different intraoperative fluoroscopic views:the control group of 20 cases, treated with standard anteroposterior and lateral fluoroscopic view;25 cases in the observation group, additional lateral oblique fluoroscopic view and dorsal tangential view of the wrist were taken. The wrist joint function score and postoperative complications were evaluated at 6 weeks, 3 and 6 months after operation between two groups.@*RESULTS@#All 45 patients were followed up and the duration ranged from 6 to 14 months, with an average of (10.8±1.7) months, all patients achieved bone union and the incision healed well. The incidence of postoperative complications in the observation group was lower than that in the control group, and the difference was statistically significant (P<0.05). In terms of Gartland-Werley score of wrist joint function, the score of wrist function in the observation group was (4.58±1.31) at 6 weeks, (2.98±0.63) at 3 months and (1.95±0.65) at 6 months post-operatively, which were better than those in the control group (6.32±1.96) at 6 weeks, (3.63±0.76) at 3 months and (2.43±0.73) at 6 months. The difference was statistically significant (P<0.05). In the observation group, 7/25 cases(28%) were found to have screw penetration during the operation by additional lateral oblique and dorsal tangential radiograph fluoroscopic views of wrist.@*CONCLUSION@#The addition of lateral oblique and dorsal tangential during the operation could improve the accuracy of distal screw placement, reduce postoperative complications, and achieve early functional exercise.

ABSTRACT

Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred. For the older patients(≥35 years old) with degeneration and wear of glenoid labrum, biceps tenodesis is more preferable, and interference screw fixation technique is recommended. As for patients with failed SLAP repair, biceps tenodesis can achieve a high success rate as a revision surgery. By review of the relevant literature in recent years, this paper summarizes the adaptation of different surgical methods of arthroscopic treatment of SLAP injury, intraoperative anchoring techniques, fixation methods and other improved surgical techniques.

ABSTRACT

The shoulder joint is the most flexible joint in the body with the largest range of motion, and the movement pattern is more complex. Accurate capture of three-dimensional motion data of the shoulder joint is crucial for biomechanical evaluation. Optical motion capture systems offer a non-invasive and radiation-free method to capture shoulder joint motion data during complex movements, enabling further biomechanical analysis of the shoulder joint. This review provides a comprehensive overview of optical motion capture technology in the context of shoulder joint movement, including measurement principles, data processing methods to reduce artifacts from skin and soft tissues, factors influencing measurement results, and applications in shoulder joint disorders.

ABSTRACT

OBJECTIVE@#To systematically evaluate obesity on the outcome of rotator cuff repair.@*METHODS@#Literatures on the relationship between obesity and outcomes after rotator cuff repair were searched from PubMed, Embase, Cochrane Library, Web of Science, China biology medicine(CBM), CNKI, Wanfang and VIP databases from building database to August 1, 2022, and were screened independently by two authors according to inclusion and exclusion criteria. Endnote X9 and Excel 2019 were used for literature extraction, management and data entry, and Newcastle-Ottawa Scale (NOS) was used to evaluate quality of the included literatures. STATA 16.0 and RevMan 5.4 softwares were used to evaluate postoperative retear rate, reoperation rate, complication rate, American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale (VAS), operative time and external rotation angle of shoulder joint pain were analyzed.@*RESULTS@#Totally 13 literatures were included, including 6 retrospective studies, 5 case-control studies, 1 prospective cohort study, and 1 abstract of a study for which the full text was not available, with 85 503 patients (31 973 in obese group and 53 530 in non-obese group). Meta-analysis showed there were statistical differences between two groups in retear rate [OR=2.58, 95%CI(1.23, 5.41), P=0.01], reoperation rate[OR=1.31, 95%CI(1.21, 1.42), P<0.00], complication rate [OR=1.57, 95%CI(1.31, 1.87), P=0.00], ASES score[MD=-3.59, 95%CI(-5.45, -1.74), P=0.00], and VAS[MD=0.24, 95%CI(0.00, 0.49), P=0.05]. While there were no differences between two groups in operative time[MD=6.03, 95%CI(-7.63, 19.69), P=0.39], external rotation angle of shoulder joint[MD=-1.79, 95%CI(-5.30, 1.71), P=0.32].@*CONCLUSION@#Obesity is associated with higher rates of retear, resurgery, complications, poorer shoulder function and pain after rotator cuff repair.
