Fossil remains of snakes in Quaternary localities are most often represented by vertebrae.Therefore,it is necessary to carry out a comparative study of the vertebrae of modern species in the areas of interest to identify fossil materials.In this study,we examined 52 specimens of viperids(7 specimens of Gloydius intermedius,12 specimens of Gloydius ussuriensis,6 specimens of Gloydius halys,4 specimens of Vipera sakhalinensis,16 specimens of Vipera berus,and 7 specimens of Vipera renardi).The features of the trunk,cervical,cloacal and caudal vertebrae of 6 species from 2 genera are described.The vertebrae of the Viperidae are highly similar across species,with variation along the vertebral column.Nevertheless,they can be distinguished if their exact position within the vertebral column is known.The most important diagnostic feature is the shape of the hypapophysis,especially when identifying the cervical vertebrae.Among other morphological features,it is important to consider the shape of the ventral surface of the vertebra,prezygapophyseal and parapophyseal processes,neurapophysis,and zygapophysis.For the epistropheus,the position of the anterior edge of the neurapophysis in relation to the anterior edge of the neural arch is also significant.The caudal vertebrae bear the greatest resemblance.There is a significant overlap between the ratios of different measurements(indices)in different species.However,if an index is out of the overlapping zone,it is possible to identify a vertebra more or less accurately,especially when considering it in conjunction with other indices and morphological characteristics. 展开更多

BACKGROUND Although percutaneous vertebral augmentation(PVA)is a commonly used procedure for treating vertebral compression fracture(VCF),the risk of vertebral refracture should be considered.Chronic kidney disease-mineral and bone disorder(CKD-MBD)is a systemic disease of mineral and bone metabolism.It is associated with an increased risk of fracture.Few studies have reported the use of PVA in patients with CKD-MBD.We herein report a rare case wherein the cemented vertebra and the adjacent vertebra refractured simultaneously in a CKD-MBD patient after PVA.CASE SUMMARY A 74-year-old man suffered from low back pain after taking a fall about 3 wk ago.According to physical examination,imaging and laboratory findings,diagnoses of T12 VCF,CKD-MBD,and chronic kidney disease stage 5 were established.He then received percutaneous vertebroplasty at T12 vertebra.Fourteen weeks later,he presented with T12 and L1 vertebral refractures caused by lumbar sprain.Once again,he was given PVA which was optimized for the refractured vertebrae.Although the short-term postoperative effect was satisfactory,he reported chronic low back pain again at the 3-month follow-up.CONCLUSION It is necessary that patients with CKD-MBD who have received PVA are aware of the adverse effects of CKD-MBD.It may increase the risk of vertebral refracture.Furthermore,the PVA surgical technique needs to be optimized according to the condition of the patient.The medium-and long-term effects of PVA remain uncertain in patients with CKD-MBD. 展开更多

BACKGROUND The appendix vermiformis is a part of the gastrointestinal tract,situated in the lower right quadrant of the abdomen.Acute appendicitis,acute inflammation of the appendix vermiformis,is the most common cause of acute abdomen requiring surgical intervention.Although computed tomography(CT)offers high diagnostic efficacy in assessing the appendix across various anatomical positions,it also involves radiation exposure.Reducing exposure factors and narrowing the field of view(FOV)are ways to decrease the radiation dose to the patient.To narrow the FOV,appendix locations within the population must be defined using metric markers.AIM To determine the location of the appendix vermiformis on CT using the vertebrae and the right iliac bone as anatomical landmarks.METHODS This retrospective study examined 470 patients presenting with abdominal pain who underwent abdominal CT scans between January 01,2015 and January 01,2018.Forty-three patients were excluded due to various reasons.The most superior and inferior points and the origin of the appendix were measured separately in relation to the vertebrae and right iliac bone for localization.The population was divided into normal and acute appendicitis groups,and the relationship between appendix location and anthropometric parameters relationship was examined.P values below 0.05 were considered statistically significant.RESULTS The final analysis included 427 adult patients(206 females and 221 males)with a mean age of 42.1±19.5 years.An ascending appendix course was the most common(90.4%).The appendix ranged from the L2 vertebral body level to the coccygeal vertebral level relative to the vertebrae.The appendix ranged between(−)140.5 mm and(+)87.4 mm relative to the right iliac bone.A negative correlation was found between patient age,height,body mass index,and the highest and lowest points of the appendix in regard to the vertebrae.CONCLUSION The study’s findings unveiled the locations of the appendix in the population in relation to the bony anatomical landmarks.These data can be used as the basis for future research aimed at reducing patient exposure to ionizing radiation. 展开更多

Objective:To investigate the clinical efficacy and safety of percutaneous kyphoplasty at different surgical timings in the treatment of osteoporotic vertebral compression fracture(OVCF)based on the theory of“dynamic-static integration”.Methods:Patients with OVCF who underwent percutaneous kyphoplasty in our hospital were selected and divided into Groups A,B,and C for those undergoing surgery within 7,7—21,and>21 days of fracture occurrence.The variations in the amount of bone cement injected,pre-and post-operative pain levels,functional activity,deformity correction of the injured vertebrae,bone cement leakage,and vertebral body height loss were compared among the three groups.Results:Regarding pain relief and functional activity,the postoperative Visual Analog Scale and Oswestry Disability Index scores of the three groups significantly improved.Furthermore,the deformities of the injured vertebrae in the three groups were significantly corrected,with Groups A and B exhibiting superior correction compared to Group C.Moreover,the bone cement leakage rates in groups A and C were higher than that in Group B.At the 3-month follow-up,the loss of vertebral height in Group C was significantly higher than those in groups A and B.Conclusion:Kyphoplasty is effective for OVCF treatment.Early surgery can effectively restore the vertebral height of the injured vertebra,reduce kyphosis,and reduce height loss of the injured vertebra after surgery;nevertheless,treatment within 1—3 weeks of the fracture can reduce the occurrence of bone cement leakage,making the surgery safer.Therefore,surgical treatment within 1—3 weeks of fracture is safer and can achieve satisfactory therapeutic effects.From the perspective of traditional Chinese medicine,PKP surgery can transform the fracture end from a micromotion state to a fixed state,which fully embodies the theory of“dynamic-static integration”. 展开更多

To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A (n=20) were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B (n=50) did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B (group A: 6.4 degree; group B: 5.4 degree)/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B (P=0.0001). Postoperatively, greater anterior height was achieved in group A than in group B (P〈0.01). During follow-up study, anterior vertebral height was maintained only in Group A (P〈0.001). Both group A and group B showed good Denis pain scores (P1 and P2) but group A outdid group B in terms of control of severe and constant pain (P4 and P5). By Frankel criteria, the changes in neurological functions in group A was better than those of group B (P〈0.001). It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting. 展开更多

Although quantitative trait loci(QTLs) for number of thoracic-lumbar vertebrae have been identified on Sus scrofa chromosomes(SSCs) 1 and 7, the influence of these QTLs on the thoracic and lumbar vertebrae is not clear. The aim of this study was to identify single nucleotide polymorphisms(SNPs) associated with total number of thoracic-lumbar vertebrae and for each trait(number of thoracic and lumbar vertebrae) separately. A total of 581 individuals from an F2 Large White×Minzhu population were genotyped using an SNP60 K chip. Performing a genome-wide association study(GWAS) for total number of thoracic-lumbar vertebrae, 38 significant SNPs were identified in two QTL regions located on SSC1 and SSC7. Performing a GWAS for number of thoracic vertebrae only, 72 significant SNPs were located on SSC7. While performing a GWAS for number of lumbar vertebrae only, 17 significant SNPs were identified on SSC1. Gene mining suggested that the gene encoding orphan nuclear receptor, germ cell nuclear factor(NR6A1) on SSC1 was a strong candidate affecting the number of lumbar vertebrae in pigs. Additionally, genes encoding vertnin(VRTN), prospero homeobox 2(PROX2), Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog(FOS), and transforming growth factor beta 3(TGFB3) may be important candidates affecting the number of thoracic vertebrae in pigs. QTLs on SSC1 and SSC7 independently influenced the numbers of thoracic and lumbar vertebrae. These results shed light on the complex genetic background of vertebrae development in pigs. 展开更多

To evaluate the therapeutic efficacy of Yinxing Damo (银杏达莫, YXDM) combined with Betahistine Hydrochloride Injection (BHI) on vertebra basilar artery ischemic vertigo (VBIV). Methods: Ninety patients with VBIV were randomly divided into two groups; 45 patients (the treated group) were treated with YXDM and BHI intravenous dripping, once a day for 14 days. Another 45 patients (control group) were treated with Xueshuantong (血栓通) and BHI intravenous dripping, once daily for 14 days. The clinical syndromes and the index of the transcranial Doppler (TCD) and hemorheology were observed. Results: The total effective rate was 100% in the treated group, which was better than that in the control group 90.5%, (P〈0. 05). The indexes of TCD and hemorheology in the treated group were obviously improved after treatment, (P〈0.01). Conclusion: YXDM combined with BHT injection had better effect in treating patients with VBIV is an ideal drug for VBIV. 展开更多

BACKGROUND As one of the most common complications of osteoporosis,osteoporotic vertebral compression fracture(OVCF)increases the risk of disability and mortality in elderly patients.Percutaneous vertebroplasty(PVP)is considered to be an effective,safe,and minimally invasive treatment for OVCFs.The recollapse of cemented vertebrae is one of the serious complications of PVP.However,the risk factors associated with recollapse after PVP remain controversial.AIM To identify risk factors for the recollapse of cemented vertebrae after PVP in patients with OVCFs.METHODS A systematic search in EMBASE,MEDLINE,the Cochrane Library,and PubMed was conducted for relevant studies from inception until March 2020.Studies investigating risk factors for the recollapse of cemented vertebrae after PVP without additional trauma were selected for analysis.Odds ratios(ORs)or standardized mean differences with 95%confidence interval(CI)were calculated and heterogeneity was assessed by both the chi-squared test and the I-squared test.The methodological quality of the included studies was assessed according to the Newcastle-Ottawa Scale.RESULTS A total of nine case-control studies were included in our meta-analysis comprising 300 cases and 2674 controls.The significant risk factors for the recollapse of cemented vertebrae after PVP in OVCF patients were fractures located at the thoracolumbar junction(OR=2.09;95%CI:1.30 to 3.38;P=0.002),preoperative intravertebral cleft(OR=2.97;95%CI:1.93 to 4.57;P<0.00001),and solid lump distribution pattern of the cement (OR = 3.11;95%CI: 1.91 to 5.07;P < 0.00001).The analysis did not support that age, gender, lumbar bone mineral density,preoperative visual analogue scale score, injected cement volume, intradiscalcement leakage, or vertebral height restoration could increase the risk forcemented vertebra recollapse after PVP in OVCFs.CONCLUSIONThis meta-analysis suggests that thoracolumbar junction fractures, preoperativeintravertebral cleft, and solid lump cement distribution pattern are associatedwith the recollapse of cemented vertebrae after PVP in OVCF patients. 展开更多

Objective To investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. Methods Orchiectomized and ovariectomized rat models are used to investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. A rat vertebral body can be longitudinally divided into central portion, which contain more trabecular bone, and para-endplate portions which contain more compact bone. In matured male and female Wistar and Sprague-Dawley rat lumbar spines, we investigated baseline bone mineral density (BMD) characteristics and the differential segmental responses in bone loss within the lumbar vertebral body post gonadal surgery with clinical multidetector computed tomography. Results Para-endplate sections had a higher BMD than central sections. The cephalad para-endplate sections had a higher BMD than the caudad para-endplate sections. Eight weeks after gonadal removal, there was more bone loss in central sections than para-endplate sections. The relative difference of bone loss between para-endplate and central sections was more apparent in male rats than in female rats. There was more bone loss in caudad sections than cephalad sections; this lead to a further increase of BMD difference between caudad para-endplate sections and cephalad para-endplate sections post gonadal surgery. Conclusion The approach described in this study provided a consistent way to study BMD change within predominantly compact bone portion and trabecular bone portion of the vertebral body. 展开更多

Numbers of vertebrae is an important economic trait associated with body size and meat productivity in animals.However,the genetic basis of vertebrae number in donkey remains to be well understood.The aim of this study was to identify candidate genes affecting the number of thoracic(TVn)and the number of lumbar vertebrae(LVn)in Dezhou donkey.A genome-wide association study was conducted using whole genome sequence data imputed from low-coverage genome sequencing.For TVn,we identified 38 genome-wide significant and 64 suggestive SNPs,which relate to 7 genes(NLGN1,DCC,SLC26A7,TOX,WNT7A,LOC123286078,and LOC123280142).For LVn,we identified 9 genome-wide significant and 38 suggestive SNPs,which relate to 8 genes(GABBR2,FBXO4,LOC123277146,LOC123277359,BMP7,B3GAT1,EML2,and LRP5).The genes involve in the Wnt and TGF-βsignaling pathways and may play an important role in embryonic development or bone formation and could be good candidate genes for TVn and LVn. 展开更多
