BACKGROUND:The biomechanical analysis of scoliosis cases is limited,with only independent analysis focusing on the spine or lower limbs,thus lacking a comprehensive evaluation of the multidimensional body.As a result,it becomes challenging to reflect the movement relationship between the trunk and lower limbs during daily activities,which hinders comprehensive clinical treatment guidance. OBJECTIVE:To explore the relationship between different segments of the spine and the kinematics/kinetics of the lower limbs during gait activities by measuring spinal kinematics in scoliosis patients,to provide a comprehensive and multi-level assessment of the biomechanical differences between scoliosis patients and the normal population,consequently offering evidence-based guidance for the prevention and treatment of scoliosis. METHODS:A cross-sectional study was conducted from July 2020 to June 2021 at the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine in Fuzhou University City.A total of 28 scoliosis patients and 28 normal individuals in the same age group were included.Three-dimensional motion capture system was used to capture gait kinematic data at a sampling frequency of 100 Hz.Two force plates(AMTI 400600,sampling frequency 1 500 Hz)were embedded in a 10-meter-long 2.4-meter-wide level ground walkway(with an effective data collection length of 4 m)to collect kinetic data.The differences in spatial-temporal parameters,kinematics,and kinetics of gait between the two groups were compared.Immediately after inclusion,all subjects underwent full spinal X-ray measurements to compare the differences between the scoliosis and normal groups. RESULTS AND CONCLUSION:(1)Patients with scoliosis exhibited reduced relative rotational range of motion between the shoulder and trunk,as well as between the thorax and pelvis,compared to the normal group(P<0.05).However,the rotational range of motion in the pelvis was larger in patients with scoliosis compared to the normal group(P<0.05).(2)Patients with scoliosis showed decreased range of motion in the hip and knee joints,as well as reduced peak torque in hip joint flexion and extension,and lower peak values of ground reaction forces in the concave and convex directions,in comparison to the normal group(P<0.05).(3)Patients with scoliosis demonstrated greater asymmetry indices in knee joint range of motion,relative rotational range of motion between the shoulder and trunk,and between the thorax and pelvis,when compared to the normal group(P<0.05).(4)These findings illustrate a rigid movement pattern among the shoulder,thorax,and pelvis in patients with scoliosis during level walking.There is a reduction in range of motion in the hip and knee joints,as well as decreased peak torque values in hip joint flexion and extension,and ground reaction forces in the concave and convex directions.These characteristics can serve as foundational elements for assessing rehabilitation and developing treatment plans.

A retrospective study was conducted on data of 23 patients with pancreatic duct diseases who were underwent peroral pancreatoscopy (POPS) at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from August 2020 to October 2022. The intraoperative observation, postoperative complications, and the diagnosis and treatment of POPS for pancreatic duct diseases were analyzed. All patients underwent POPS and achieved technical success. Among them, 7 patients were diagnosed as having intraductal papillary mucinous neoplasm of pancreas and 3 pancreatic malignant tumor. Eight patients with pancreatolithiasis accepted laser or eletrohydraulic lithotripsy under POPS. Abdominal pain improved in 2 patients with chronic pancreatitis after treatment. Melena disappeared in 2 patients with pancreatic duct hemorrhage or pancreatic enterostomy inflammation after conservative treatment. The symptom of 1 patient with pancreatic enterostomy stenosis improved after balloon dilation. There was no complication in the 23 patients, and the operation time was 35-90 min. The results indicate POPS is safe, effective with distinctive advantages in the diagnosis and treatment for pancreatic duct diseases.

Objective:To evaluate the value of CT angiography (CTA) for vertebral artery (VA) injury in the transverse foramen region of cervical vertebra.Methods:The clinical and CTA imaging data of 56 patients with cervical spine trauma in People's Hospital of Yuxi City from January 2016 to December 2019 were retrospectively analyzed. To observe the VA were or not injuried and their degrees, and the relationship between fracture in transverse foramen region and injured of the VA by applying post processing techniques such as volume reconstruction (VR), image fusion, curved planar reconstruction (CPR), multi-planar reconstruction (MPR), vascular analysis and so on.Results:There were 35 cases in the positive group of transverse perforation stenosis among the 56 patients, and 21 cases in the negative group. There were 19 cases injuried the VA in the positive group of stenosis, but just 5 cases′VA were injuried in the negative group of stenosis, with statistically significant differences ( P<0.05). The risk of VA injuried caused by different degrees of transverse perforation stenosis in the positive stenosis group was statistically significant ( P<0.05). The VA damaged distribution were: 3 cases in V1 segment, 16 cases in V2 segment, 5 cases in V3 segment. The degree of luminal stenosis were: 9 cases of mild stenosi, 7 cases of moderate stenosis, 5 cases of severe stenosis, and 3 cases of luminal occlusion. Conclusions:The CTA of VA can clearly show its anatomical route, degree of injury, range and its adjacent relationship with the fracture end of the transverse foramina of cervical vertebra, which can provide evidences of objective and reliable imaging for spinal surgeons to assess their conditions and select the treatment plans.

Objective To analyze the identification, drug resistance and clinical significance of a rare bacterium of Bordetella holmesii ( B. holmesii) to improve its detection and clinical diagnosis and treat-ment. Methods A strain isolated from a bacteremia case was identified by bacterial culture, biochemical tests and 16S rRNA gene sequencing. Mega 7. 0 software was used to conduct a similarity analysis of 16S rRNA gene sequences between the type strains of Bordetella spp. and the isolate, and then a phylogenetic tree was constructed. Antibiotic resistance of the isolate was determined by E-test. Changes in bacterial growth were measured after adding different concentrations of riboflavin or its inhibitor lumiflavin to the cul-ture medium. Results B. holmesii ABD2 was the pathogen causing bacteremia in the immunocompetent pa-tient. It was deposited under the number of CGMCC 1. 13721 in China General Microbiological Culture Col-lection Center (CGMCC), and the 16S rRNA gene sequences were deposited in National Center for Biotech-nology Information ( NCBI) with the accession number of KT828544. 1. Unrooted tree showed that the B. holmesii strain was highly homologous with B. pertussis. Antibiotic susceptibility test showed that the mini-mum inhibitory concentrations ( MIC) of piperacillin, ceftazidime, cefepime, imipenem, meropenem, cipro-floxacin, levofloxacin, gentamicin, amikacin, erythromycin, tetracycline and polymyxin B against the isolate were low, while the MIC values of cefazolin, cefuroxime, cefoxitin, cefotaxime, aztreonam and trime-thoprim-sulfamethoxazole were high. Riboflavin accelerated the growth of B. holmesii ABD2, while its inhibi-tor lumiflavin had an inhibitory effect. Conclusions As B. holmesii is hard to isolate and identify, limited clinical, microbiological and epidemiological data are available. It is an under-recognized pathogen with a considerable amount of information that remains to be studied.

Non-coding RNAs (ncRNAs) are genomic transcripts that do not encode proteins.They are also closely associated with tumor initiation and progression,as they play regulatory roles in gene transcription,post-transcription,and translation.Moreover,ncRNAs may enter circulatory system in the form of microvesicles or exosomes,or in combination with protein.The circulating ncRNAs are stable and widely existed in body fluids such as blood and urine.Certain circulating ncRNAs are differentially expressed in tumors,suggesting that they have potential value as novel tumor biomarkers.This article briefly reviews the progress of circulating microRNA (miRNA),long non-coding RNA (lncRNA) and circular RNA (circRNA) as breast cancer biomarkers,and discusses the clinical value of circulating ncRNA as a novel biomarker for breast cancer diagnosis and prognosis.

Objective To investigate the influencing factors of epileptic seizure in chronic renal failure (CRF) patients.Methods CRF patients,admitted to our hospital from March 2014 to October 2018,were chosen in our study,and divided into epilepsy group (n=40) and non-epilepsy group (n=3653) according to whether the patients were with or without epilepsy.Clinical data,as length of hospital stays,dialysis methods,presences of infection,sites of infection,and use of antibiotics,and laboratory variables,as blood routine examination,straw aminotransferase (AST),and alanine aminotransferase (ALT),were collected and retrospectively analyzed.Logistic regression analysis was used to determine the independent factors affecting seizures in patients with CRF.Results The patients in the epilepsy group had significantly longer duration of dialysis and length of hospital stays,statistically higher incidence of infection and proportion of dialysis,and significantly worse prognosis than the patients from non-epilepsy group (P＜0.05).The leukocyte count of the epilepsy group was significantly higher than that of the non-epilepsy group,the contents of hemoglobin,ALT and albumin were significantly lower than those of the non-epilepsy group,and the contents of urea nitrogen,creatinine and serum potassium were significantly higher than those of the non-epilepsy group (P＜0.05).Logistic regression analysis showed that epilepsy was associated with serum potassium,creatinine,urea nitrogen and dialysis.Conclusion The etiology of epilepsy is complex,which is related to dialysis,toxin levels,and electrolyte imbalance;the mortality rate of those patients is high and the prognosis is not good.

Objective To evaluate the changes of adenosine metabolism pathway related molecules and their contribution to inflammatory injury in primary biliary cholangitis (PBC).Methods The consecutive samples of 49 subjects with PBC from The First People's Hospital of Taicang and The Second People's Hospital of Changshu were recruited from October 2016 to October 2017,and 36 healthy controls were involved in this study.The expression of CD39 and CD73 on CD4+T cells and Foxp3 + regulatory T cells were assayed by flow cytometry and the concentration of adenosine triphosphate (ATP) in serum was analyzed by ultraperformance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF/MS).The correlations between Tregs,ATP and liver function were analyzed,i.e.,alanine aminotransferase (ALT),aspartate aminotransferase (AST),gamma-glutamyltransferase (GGT),alkaline phosphatase (ALP) and Mayo scores.Results In the patients with PBC,low proportions of CD4+CD39+T cells were noted compared with healthy controls [(5.28 ± 1.92) ％ vs (11.0l ± 3.19) ％,t =10.25,P ＜ 0.01].The patients with PBC also had significantly low proportion of CD4+CD25 + Foxp3+ CD39+ T cells compared with healthy controls [(23.75 ± 9.48) ％ vs (54.68 ± 5.18) ％,t =13.79,P ＜0.01].No significant difference of the proportion of CD4+CD73+T or CD4+CD25+ Foxp3+CD39+T cells was found between PBC and control groups (t values were 2.235 and 1.083,P ＞ 0.05).The level of serum ATP was higher in the patients with PBC than that of healthy controls [(200.28 ± 79.41) μg/L vs (89.20 ± 33.76) μg/L,t =8.367,P ＜ 0.01].A significant correlation was demonstrated between the proportion of CD39 + Treg in total Treg cells and the levels of ATP (r =-0.413,P =0.003),GGT (r=-0.378,P=0.007) and Mayo score (r=-0.382,P=0.007).Conclusion The low proportion of CD39+ Treg cells may contribute to the down-regulation of ATP hydrolysis in the patients with PBC.No significant change of CD73 + Treg cells was found in PBC patients.

Objective: To investigate the therapeutic effect of free superficial circumflex iliac artery perforator (SCIP)flap for reconstruction of soft tissue defects secondary to resection of retromolar and lateral buccal squamous cell carcinoma. Methods: From January 2014 to January 2017, eight patients with retromolar and lateral buccal squamous cell carcinoma received radical resection and reconstructed with SCIP flap immediately. CTA and color Doppler sonography were routinely performed before the surgery. According to the size of the defect in the recipient area, the flap vascularized by the perforator vessel was carefully prepared and transferred to the buccal-pharynx-palate composite defect. The recipient area and donor area were sutured tightly after arteriovenous anastomosis under microscope. The survival and functional recovery of the flap were observed after operation. Results: The flap sizes ranged from 5 cm× 6 cm to 7 cm×9 cm.The mean diameter of the superficial circumflex iliac arteries was 0.65 mm. And the mean diameter of the veins was 1.2 mm. The mean arterial pedicle length was 7.0 cm, and the venous pedicle length was 8.0 cm. Eight flaps were all survived. The shape of the buccal-parapharyngeal-palate was good and the mouth opening was normal after operation. Conclusions Superficial circumflex iliac artery perforator flap was a good choice for repairing the defect of parapharyngeal squamous cell carcinoma in the posterior molar region.

[Objective] Based on the resting state functional magnetic resonance imaging to investigate the abnormal features of the functional connectivity of resting brain neural network in the patients with primary insomnia,by using voxel-wise whole-brain finctional networks analysis of degree centrality (DC) for imaging evidence of neural mechanisms underlying primary insomnia.[Methods] The resting state fMRI were performed in 59 PI patients and 47 age,education,and sex-matched normal healthy subjects.Analysis of DC map changes between the two patient groups and the control group were performed by two sample t test.(threshold at P ＜ 0.05).[Results] Compared with the control group,the patients with PI showed significantly reduced DC value in bilateral medial frontal gyrus (MFG),bilateral anterior cingulate gyrus (ACG),and right insula;and increased DC value in right middle temporal gyrus (MTG),and left cuneus,(CUN),P ＜ 0.05.[Conclusion]Changes of DC value occurred in some region of brain in the P[patient groups when compared with the control group.It was indicated that DC,as a novel resting-state fMRI parameter in the voxel-wise whole-brain functional networks,might be an appealing alternative approach for further study on pathologic and neuropsychological states of PI.
