ABSTRACT

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

ABSTRACT

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.

ABSTRACT

Objective:To investigate the clinical effect of Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis in the treatment of qi deficiency, blood stasis and dampness and turbidity in chronic kidney disease (CKD) stage 5.Methods:Randomized controlled trial. A total of 102 elderly CKD stage 5 patients with Qi and Yin deficiency and turbid poison inherent type were selected from May 2021 to January 2022 of the Beijing Longfu Hospital. The patients were divided into two groups by random number table method. Control group (51 cases) received hemodialysis treatment for 4 weeks, and the observation group (51 cases) received Shenqi Dihuang Decoction and Xiaochengqi Decoction enema combined with hemodialysis treatment for 4 weeks. The levels of BUN, SCr and β2-microglobulin (β2-MG), and K +, Ca 2+, P 3- content, hemoglobin were detected by automatic blood cell analyzer, and serum CRP and IL-6 levels were detected by latex enhanced immune scattering turbidimetry. The adverse reactions during the treatment and evaluate the clinical efficacy were observed and recorded. Results:During the treatment, 2 patients in the observation group withdrew from the study due to severe diarrhea, and other patients completed the study. There were significant differences in total response rate between observation group and control group [91.84%(45/49) vs. 74.51%(38/51); χ2=5.32, P=0.002]. After treatment, scores of lumbar and knee acerbity, tiredness and fatigue, edema, dizziness and tinnitus, fear of cold and warm, yellow face, dry stool and total score in observation group were significantly lower than those in the control group ( t=8.38, 13.44, 15.14, 13.09, 7.12, 7.73, 11.16, 11.45, P<0.01); the scores of SF-12-PCS and SF-12-MCS were significantly higher than those in the control group ( t=3.24, 4.22, P<0.01). After treatment, levels of serum BUN [(15.02±2.35)mmoL/L vs. (18.02±3.65)mmoL/L, t=4.87], SCr[(155.26±23.65) μmol/L vs. (184.49±35.49) μmol/L, t=4.83], β2-MG[(7.12±1.27)mg/L vs. (9.56±2.14)mg/L, t=6.90] and P 3-[(1.51±0.10) mmol/L vs. (2.02±0.19) mmol/L, t=16.70], K +[(3.65±0.54) mmol/L vs. (4.21±0.63)mmol/L, t=4.76] in observation group were significantly lower than those in the control group ( P<0.01); Ca 2+[(1.86±0.36)mmol/L vs. (2.35±0.42)mmol/L, t=6.25] was significantly higher than that of the control group ( P<0.01). No adverse reactions occurred during the treatment in the two groups ( P>0.05). Conclusion:Shenqi Dihuang Decoction and Xiaochengqi Decoction enema and hemodialysis can improve renal function, correct electrolyte disorder, reduce the level of inflammatory factors, improve the quality of life, and improve the therapeutic effect of the patients with CKD stage 5 and Qi and Yin deficiency and turbid poison inherent pattern.

ABSTRACT

Because the classification system of radical surgery for rectal cancer has not been established, it is impossible to select the appropriate surgical method according to the clinical stage of the tumor. In this paper, we explained the theory of " four fasciae and three spaces " of pelvic membrane anatomy and then combined this theory with the membrane anatomical basis of Querleu-Morrow classification for radical cervical cancer resection. Based on this theory and the membrane anatomy of Querleu-Morrow classification of radical cervical cancer resection, we proposed a new classification system of radical rectal cancer surgery based on membrane anatomy according to the lateral lymph node dissection range of the rectum. This system classifies the surgery into four types (ABCD) and defines corresponding subtypes based on whether the autonomic nerve was preserved. Among them, type A surgery is total mesorectal excision (TME) with urogenital fascia preservation, type B surgery is classical TME, type C surgery is extended TME, and type D surgery is lateral extended resection. This classification system unifies the anatomical terminology of the pelvic membrane, validates the feasibility of using the " four fasciae and three fascial spaces " theory to classify rectal cancer surgery, and lays the theoretical foundation for the future development of a unified and standardized classification of radical pelvic tumor surgery.

ABSTRACT

Chinese medicinal resources are the cornerstone of the sustainable development of traditional Chinese medicine industry. However, due to the fecundity of species, over-exploitation, and limitations of artificial cultivation, some medicinal plants are depleted and even endangered. Tissue culture, a breakthrough technology in the breeding of traditional Chinese medicinal materials, is not limited by time and space, and can allow the production on an annual basis, which plays an important role in the protection of Chinese medicinal resources. The present study reviewed the applications of tissue culture of medicinal plants in the field of Chinese medicinal resources, including rapid propagation of medicinal plant seedlings, breeding of novel high-yield and high-quality cultivars, construction of a genetic transformation system, and production of secondary metabolites. Meanwhile, the current challenges and suggestions for the future development of this field were also proposed.

ABSTRACT

Osteoporotic vertebral compression fracture (OVCF) can lead to lower back pain and may be even accompanied by scoliosis, neurological dysfunction and other complications, which will affect the daily activities and life quality of patients. Vertebral augmentation is an effective treatment method for OVCF, but it cannot correct unbalance of bone metabolism or improve the osteoporotic status, causing complications like lower back pain, limited spinal activities and vertebral refracture. The post-operative systematic and standardized rehabilitation treatments can improve curative effect and therapeutic efficacy of anti-osteoporosis, reduce risk of vertebral refracture, increase patient compliance and improve quality of life. Since there still lack relevant clinical treatment guidelines for postoperative rehabilitation treatments following vertebral augmentation for OVCF, the current treatments are varied with uneven therapeutic effect. In order to standardize the postoperative rehabilitation treatment, the Spine Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized relevant experts to refer to relevant literature and develop the "Guideline for postoperative rehabilitation treatment following vertebral augmentation for osteoporotic vertebral compression fracture (2022 version)" based on the clinical guidelines published by the American Academy of Orthopedic Surgeons (AAOS) as well as on the principles of scientificity, practicality and advancement. The guideline provided evidence-based recommendations on 10 important issues related to postoperative rehabilitation treatments of OVCF.

ABSTRACT

Objective:To investigate the clinical efficacy of distal tibiofibular screw fixation combined with ligament repair for the treatment of ankle fracture accompanied with distal tibiofibular syndesmosis injuries.Methods:A retrospective cohort analysis was made on clinical data of 72 patients with ankle fracture accompanied with distal tibiofibular syndesmosis injuries admitted to 909th Hospital of Joint Service Support Force of PLA from September 2017 to September 2020, including 38 males and 34 females, aged 19-65 years [(42.5±12.2)years]. The fracture was type B in 30 patients, type C 1 in 29 and type C2 in 13 according to Danis-Weber classification. A total of 36 patients were treated by distal tibiofibular screw fixation combined with ligament repair (fixation+repair group) and 24 patients by distal tibiofibular screw fixation (fixation group). Operation time, intraoperative blood loss and hospital stay were recorded. Visual analogue scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot score and ankle range of motion (ROM) were determined at 1, 3 months postoperatively and at the final follow-up. Complications were documented. Results:All patients were followed up for 12-22 months [(15.9±2.2)months]. There were no significant differences in operation time, intraoperative blood loss and hospital stay between the two groups (all P>0.05). VAS in fixation+repair group was (3.1±1.0)points and (2.1±0.6)points at 1, 3 months postoperatively, significantly lower than (3.9±0.8)points and (2.6±0.8)points in fixation group (all P<0.05), but the score showed no significant difference between the two groups at the final follow-up ( P>0.05). AOFAS score in fixation+repair group was (64.7±4.0)points, (73.2±3.4)points and (87.2±3.4)points at 1, 3 months postoperatively and at the final follow-up, significantly higher than (60.1±4.9)points, (70.2±1.9)points and (84.1±2.6)points in fixation group (all P<0.05). There was no significant difference in the ROM between the two groups at 1 month postoperatively ( P>0.05), but the ROM at 3 months postoperatively and at the final follow-up in fixation+repair group [(44.4±2.9)° and (52.3±2.5)°, respectively] was significantly higher than that in fixation group [(41.4±2.7)° and (50.1±2.7)°, respectively] (all P<0.05). There was 1 patient with internal fixation loosening in fixation+repair group, with the incidence of complications of 3% (1/36). While the incidence of complications was significantly lhigher in fixation group [17%(6/36)], including 2 patients with re-separation of distal tibiofibular syndesmosis, 2 with internal fixation loosening and 2 with internal fixation breakage ( P<0.05). Conclusion:Compared with distal tibiofibular screw fixation, distal tibiofibular screw fixation combined with ligament repair for the treatment of ankle fracture accompanied with distal tibiofibular syndesmosis injuries is effective to early relieve ankle pain, improve ankle function and ROM, and reduce occurrence of complications.

ABSTRACT

The unipolar/bipolar pacing mode of pacemaker is related to its circuit impedance, which affects the battery life. In this study, the in vitro experiment scheme of pacemaker circuit impedance test was constructed. The human blood environment was simulated by NaCl solution, and the experimental environment temperature was controlled by water bath. The results of in vitro experiments showed that under the experimental conditions similar to clinical human parameters, the difference between the circuit impedance of bipolar mode and unipolar mode is 120~200 Ω. The results of the in vitro experiment confirmed that the circuit impedance of bipolar circuit was larger than that of unipolar mode, which was found in clinical practice. The results of this study have reference value to the optimization of pacing mode and the reduction of pacemaker power consumption.

ABSTRACT

In this paper, the name, origin, quality evaluation, producing area and processing methods of Platycodonis Radix used in the famous classical formulas are researched by consulting related materia medicas, prescription books and medical books of the past dynasties. It was found that Platycodonis Radix was the correct name in the materia medicas of the past dynasties, which was named for its "roots are strong but the stems are straight". Its dominant base of the past dynasties was Platycodon grandiflorus, and since the Ming and Qing dynasties, Hexian county of Anhui has been respected as the representative authentic producing area. In modern times, it has been concluded that the quality of Platycodonis Radix is best if the body is dry, thick and uniform, solid, white in color, and bitter in taste. In ancient times, the processing methods of Platycodonis Radix were mainly removing the reed head and floating skin, rice simmering and drying, and slicing and micro-frying. In modern times, its processing methods have been mainly simplified to peeling and cutting into thick slices. Therefore, it is recommended to use the dry roots of P. grandiflorus and its raw products in the famous classical formulas.

ABSTRACT

As a treatment of rectal cancer, lateral lymph node dissection (LLND) is still a controversial issue. The argument against LLND is that the procedure is complicated, and consequently results in a high incidence of postoperative urogenital dysfunction. The surgical modality from fascia to space is adopted by lateral lymph node dissection in "two spaces". This operation has significant advantages of clear location of nerves and blood vessels and simplified surgical procedures, so the surgical procedure can be repeated and modulated. The fascia propria of the rectum, urogenital fascia, vesicohypogastric fascia and parietal fascia constitute the dissection plane for lateral lymph node dissection.Two spaces refer to Latzko's pararectal space and paravesical space. During the establishment of fascia plane, the dissection of external iliac lymph node (No.293), commoniliac lymph node (No.273) and abdominal aortic bifurcation lymph node (No.280) can be performed. While in the "space" dissection, internal iliac lymph node (No.263), obturator lymph node (No.283), lateral sacral lymph node (No.260) and median sacral lymph node (No.270) can be removed. LD2 or LD3 lateral lymph node dissection prescribed by the Japanese Society of Colorectal Cancer can be completed according to the needs of the disease. This article describes the anatomical basis and standardized surgical procedures.

ABSTRACT

OBJECTIVES@#To study the relationship between water temperature and floating time of aquatic cadavers, providing a reference for more precise positioning and searching for floating corpses.@*METHODS@#The floating model of guinea pig after drowning at 17-30 ℃ was established, and the floating times of carcasses were recorded. The collected data of 32 floating corpse cases in the Pearl River were sorted out and analyzed according to the floating time of corpses corresponding to each degree of water temperature. The relationship models between water temperature and the floating time of guinea pig carcass, and between that and the floating time of real cases were established.@*RESULTS@#The floating time of the cadaver was negatively correlated with water temperature. The power function fitting equation of the relationship between floating time and water temperature of guinea pig carcass was y=1×1015x-10.530(R2=0.871, P<0.01), and the power function fitting equation of the relationship between corpse floating time and water temperature was y=3×106x-3.467(R2=0.802, P<0.01).@*CONCLUSIONS@#It is found that average floating cadaver time has a power function with water temperature, which provides a reference for locating floating cadavers and establishing search models.

ABSTRACT

Objective:To analyze the incidence and epidemiological characteristics of traumatic spinal cord injury in China in 2018.Methods:Multi-stage stratified cluster sampling was used to randomly select hospitals capable of treating patients with spinal cord injury from 3 regions,9 provinces and 27 cities in China to retrospectively investigate eligible patients with traumatic spinal cord injury admitted in 2018. National and regional incidence rates were calculated. The data of cause of injury,injury level,severity of injury,segment and type of fracture,complications,death and other data were collected by medical record questionnaire,and analyzed according to geographical region,age and gender.Results:Medical records of 4,134 patients were included in this study,with a male-to-female ratio of 2.99∶1. The incidence of traumatic spinal cord injury in China in 2018 was 50.484 / 1 million (95% CI 50.122-50.846). The highest incidence in the Eastern region was 53.791 / 1 million (95% CI 53.217-54.365). In the whole country,the main causes of injury were high falls (29.58%),as well as in the Western region (40.68%),while the main causes of injury in the Eastern and Central regions were traffic injuries (31.22%,30.10%). The main injury level was cervical spinal cord in the whole country (64.49%),and the proportion of cervical spinal cord injury in the Central region was the highest (74.68%),and the proportion of lumbosacral spinal cord injury in the Western region was the highest (32.30%). The highest proportion of degree of injury was incomplete quadriplegia (55.20%),and the distribution pattern was the same in each region. A total of 65.87% of the patients were complicated with fracture or dislocation,77.95% in the Western region and only 54.77% in the Central region. In the whole country,the head was the main combined injury (37.87%),as well as in the Eastern and Central regions,while the proportion of chest combined injury in the Western region was the highest (38.57%). A total of 32.90% of the patients were complicated with respiratory complications. There were 23 patients (0.56%) died in hospital,of which 17(73.91%) died of respiratory dysfunction. Conclusions:The Eastern region of China has a high incidence of traumatic spinal cord injury. Other epidemiological features include high fall as the main cause of injury cervical spinal cord injury as the main injury level,incomplete quadriplegia as the main degree of injury,head as the main combined injury,and respiratory complications as the main complication.

ABSTRACT

Objective:To evaluate the efficacy of unilateral puncture techniques in high-viscosity cement percutanueous vertebroplasty (PVP) in treatment of type I chronic symptomatic osteoporotic vertebral compression fracture (CSOVCF).Methods:A retrospective case control study was conducted to analyze the clinical data of 119 patients with type I CSOVCF admitted to Honghui Hospital affiliated to Xi'an Jiaotong University School of Medicine from December 2013 to December 2016. There were 42 males and 77 females, aged 58-95 years [(79.2±15.6)years]. All patients had bone mineral density of -4.5--2.5 SD [(-3.9±0.2)SD] (T score). The fractured segments included L 1-L 2 in 56 patients and L 3-L 5 in 63. All patients were treated by high-viscosity cement PVP with the unilateral puncture of transverse process and superior articular process in unilateral group ( n=60) and by the bilateral puncture approach with the Magerl method in bilaleral group ( n=59). The operation time, cement injection volume, and intraoperative fluoroscopy frequency were recorded. The visual analogue scale (VAS), Oswestry dysfunction index (ODI), anterior height ratio of injured vertebrae and Cobb angle were measured before operation, at postoperative 1 day and at the last follow-up. The adjacent vertebral fracture, cement leakage and other complications were recorded. Results:All patients were followed up for 12-48 months [(24.1±5.6)months]. The operation time in unilateral group [(21.5±6.5)minutes] was significantly shorter than that in bilateral group [(37.8±7.4)minutes] ( P<0.05). The cement injection volume in unilateral group [(4.2±0.7)ml] was less than that in bilateral group [(6.5±1.1)ml]( P<0.05). The intraoperative fluoroscopy frequency in unilateral group [(14.2±3.0)times] was less than that in bilateral group [(31.4±6.4)times] ( P<0.05). Both groups showed significant improvements in VAS, ODI, anterior height ratio of injured vertebrae and Cobb angle at postoperative 1 day and at the last follow-up compared with these before operation ( P<0.05), but there were no significant differences after operation between the two groups ( P>0.05). The incidence of adjacent vertebral fracture was 5%(3/60) in unilateral group and 8% (5/59) in bilaleral group ( P>0.05). Four patients (7%) had cement leakage in unilateral group and 11 patients (19%) in bilateral group ( P<0.05). No complications of wound infection, nerve injury or pulmonary embolism occurred. Conclusion:Compared with Magerl bilateral puncture approach, high-viscosity cement PVP with unilateral puncture of transverse process and superior articular process in treatment of type I CSOVCF has advantages of shorter operation time, less trauma, less radiation exposure and lower cement leakage rate.

ABSTRACT

A sensitive and efficient method was established and validated for qualitative and quantitative analysis of total alkaloids from the extract of Eurycoma longifolia by high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(HPLC-Q-TOF-MS) combined with ultra-performance liquid chromatography coupled with triple quadrupole tandem mass spectrometry(UPLC-QQQ-MS/MS). The HPLC-Q-TOF-MS conditions are as follows: Welch Ultimate XB-C_(18) column(4.6 mm×250 mm, 5 μm) with acetonitrile(containing 0.1% formic acid)-0.1% formic acid in water as mobile phase for gradient elution. The UPLC-QQQ-MS/MS conditions are as below: Agilent Eclipse Plus C_(18) column(2.1 mm×50 mm, 1.8 μm) with acetonitrile(containing 0.1% formic acid) and 0.1% formic acid in water as mobile phase for gradient elution. MS data were collected by electrospray ionization in positive ion mode. According to the comparison with reference standards and the accurate masses of molecules, a total of 17 alkaloids in E. longifolia extract were identified by HPLC-Q-TOF-MS. The UPLC-QQQ-MS/MS quantitative analysis result of 3 alkaloids showed that the linear ranges of them were good(r≥0.999 7) and the overall recoveries ranged from 108.8%-110.2%, with RSDs of 2.9%-5.3%. The method is accurate, reliable, and efficient, which can comprehensively reflect the constituents and content of alkaloids in E. longifolia. The result can serve as a reference for further elucidating its therapeutic material basis and quality control.

ABSTRACT

OBJECTIVE@#To study the mechanism of the anti-tumor effect of Morinda citrifolia (noni).@*METHODS@#The influences of noni juice on cell proliferation, apoptosis, invasion, migration and the activity of AKT/nuclear factor- κ B (NF- κ B) signaling pathway in A549 human lung cancer cells were detected by MTT, cell counting kit-8, colony formation, Annexin V/PI double labeling, transwell, scratch test and immunoblotting assay, respectively. A549 cells were inoculated into the right axilla of nude mice, followed by noni juice treatment. The body weight of the nude mice was weighed, and the tumor volume and weight were measured. Cell proliferation and expression of apoptosis-related proteins were measured by immunohistochemistry, and the activity of NF- κ B signaling pathway was measured by immunoblotting.@*RESULTS@#The in vitro studies showed that noni juice inhibited the A549 cells proliferation, migration and invasion. Noni juice also promoted cells apoptosis in A549 cells. Immunoblotting assay showed that the phosphorylation level of AKT, p50, and STAT3 proteins was inhibited to different extents after noni juice treatment. The in vivo studies showed that noni juice effectively suppressed tumor formation of A549 cells in nude mice. Noni juice treatment inhibited the expression of Ki67, PCNA, and Bcl-2 protein in the tumor; while promoted the expression of caspase-3 protein. Additionally, we also found that noni juice treatment could restrain the activity of AKT/NF- κ B signaling pathway in the tumor tissue.@*CONCLUSION@#Noni juice inhibited the proliferation of A549 lung cancer cells, induced apoptosis, and inhibited cell invasion and migration via regulating AKT/NF- κ B signaling pathway.

ABSTRACT

Objective:To explore the curative effect of the "domino" sequential method with prosthesis preservation in the treatment of infection around the prosthesis after limb salvage surgery for bone tumors.Methods:A retrospective analysis of 11 patients with peripheral prosthetic infections after limb salvage surgery with prosthesis preserving "domino" from January 2016 to January 2020 was retrospectively analyzed, including 8 males and 3 females; age 21-74 years old, with an average of 51.8 years old. There were 6 cases of knee prosthesis for distal femoral tumor, 2 cases of proximal tibia knee prosthesis, 2 cases of pelvic prosthesis infection, and 1 case of middle femoral prosthesis. Before the operation, 8 cases had fever, and 2 cases had sinus. Sequential treatment failure is defined as: recurrence of infection. The treatment method is the debridement and lavage of the prosthesis and the systemic combined local application of drug-sensitive antibiotics to evaluate the patient's blood routine, C-reflective protein, erythrocyte sedimentation rate and other indicators, X-ray and CT of the surgical site, and the Musculoskeletal Tumor Society (MSTS) score.Results:The positive rate of microorganism culture was 72.7% (8/11), including 2 cases of Staphylococcus aureus, 1 case of Staphylococcus epidermidis, 1 case of methicillin-resistant Staphylococcus epidermidis, 1 case of methicillin-resistant Staphylococcus aureus, abalone There were 2 cases of Acinetobacter mannifolia and 1 case of Streptococcus degalactiae. The MSTS score before treatment and at the last follow-up after treatment increased from 10.91±2.31 points to 20.73±3.52 points, the difference was statistically significant ( t=7.162, P<0.05). A total of 3 cases of sequential treatment failed to control infection, and the operation success rate was 72.7% (8/11). One case was amputation, one case was long-term replacement of wound dressing, and one case was switched to antibiotic bone cement combined with intramedullary nail reverse double insertion technique to control infection. Conclusion:For bone tumors with clinical infection symptoms less than one month after limb salvage surgery, the use of prosthesis-preserving "domino" sequential method for treatment of prosthetic infections is desirable for early and mid-term clinical efficacy.

ABSTRACT

Objective:To compare the clinical efficacy between puncture assisted by a "TINAVI" orthopaedic robot versus freehand puncture in vertebroplaty for osteoporotic vertebral compression fracture(OVCF) of the upper thoracic vertebra.Methods:A retrospective study was conducted of the 19 patients (20 vertebral bodies) with OVCF of the upper thoracic vertebra who had been treated at Department of Spine Surgery, Honghui Hospital from January 2018 to March 2019 by robotic vertebroplasty (robot group) and of another 21 counterpart patients (21 vertebral bodies) who had been treated by conventional vertebroplasty from January 2016 to December 2017 (freehand group). Puncture was conducted by a "TINAVI" orthopaedic robot in the robotic vertebroplasty but freehand in the conventional vertebroplasty. The robot group had 5 males and 14 females, aged from 62 to 88 years; the freehand group had 6 males and 15 females, aged from 64 to 83 years. The 2 groups were compared in terms of operation time, bone cement volume, postoperative complications (cement leakage, infection and embolism), visual analogue scale (VAS), Oswestry disability index (ODI), anterior height (AH) and kyphosis angulation (KA) of the injured vertebra at day 1 and last follow-up after surgery.Results:The 2 groups were comparable because there were no significant differences between them in the preoperative general data ( P>0.05). Vertebroplasty via unilateral puncture approach was completed uneventfully in the 19 patients (20 vertebral bodies) in the robot group and in the 21 patients (21 vertebral bodies) in the freehand group. The 40 patients were followed up for 6 to 12 months (mean, 8.3 month). The operation time [(37.9±8.2) min], bone cement volume [(2.3±0.9) mL] and rate of cement leakage (10.0%, 2/20) in the robot group were all significantly less or lower than those in the freehand group [(46.2±9.4) min, (4.2±1.3) mL and 42.9% (9/21)] ( P<0.05). No infection or embolism was observed in either group. There were no significant differences between the 2 groups in VAS, ODI, AH or KA of the injured vertebra at day 1 or last follow-up after surgery ( P>0.05). Conclusion:In vertebroplaty for OVCF of the upper thoracic vertebra, compared with conventional freehand puncture, puncture assisted by a "TINAVI" orthopaedic robot can lead to satisfactory clinical efficacy because it reduces operation time, volume of bone cement injection, and thus incidence of bone cement leakage.

ABSTRACT

Despite the concept of membrane anatomy has been widely used in minimally invasive colorectal surgery, the definition of membrane anatomy and the establishment of membrane plane remain controversial. Therefore, it is difficult to establish a unified theoretical system of membrane anatomy. Through embryological studies and anatomical findings on the integrity and continuity of membranes, we try to discuss the theoretical system of membrane anatomy in colorectal surgery from three aspects: membrane anatomical system, membrane anatomical elements and membrane anatomical mechanism. The establishment of a unified theoretical system of membrane anatomy will not only contribute to the standardization operative procedures, but also to the establishment of uniform surgical standards for colorectal cancer.

ABSTRACT

Synthetic cathinones are a class of new psychoactive substances with a structure similar to amphetamine drugs, which can produce excitatory effects similar to drugs such as amphetamine and cocaine after being taken. In recent years, the abuse of synthetic cathinones worldwide has become increasingly serious, posing a serious threat to social security and public health. This article focuses on several common synthetic cathinones, collects their research results in animal autonomous activity experiments and drug dependence model experiments and summarizes their relevant experimental conclusions in animal body temperature regulation, learning and memory, and anxiety, in order to provide data reference and method guidance for the domestic development of related drug research.

ABSTRACT

BACKGROUND: Our previous studies have found that Bushen Tiaogan prescription can significantly reduce pain and improve the clinical symptoms of traditional Chinese medicine in elderly patients with osteoporosis. The clinical effect is positive, but there is no relevant experimental evidence. OBJECTIVE: To explore the safety of Bushen Tiaogan prescription and its therapeutic effect on prednisolone-induced osteoporosis. METHODS: The zebrafish juveniles 5 hours after fertilization were evenly distributed into 24-well plates at a density of 20 per well. Different concentrations of Bushen Tiaogan prescription (crude drug concentrations 10, 50, 100, 250, 500 mg/L) were added to the corresponding wells. The development of the embryos was observed at 24, 48, 72, 96 hours after fertilization, and the cumulative survival rate and hatching rate were used to evaluate the safety of Bushen Tiaogan prescription. The zebrafish juveniles 3 days after fertilization were randomly divided into blank control group (0.5% dimethyl sulfoxide), 25 µmol/L prednisolone model group, alendronate sodium positive drug group and Bushen Tiaogan prescription (10, 50, 100, 250, 500 mg/L) groups, with 40 in each group. The culture fluid was changed every day and executed at the 8th day. Zebrafish juveniles were dyed using alizarin red for microscopic detection and digital imaging and the bone staining area was quantitatively analyzed by image software to evaluate the anti-osteoporosis activity of Bushen Tiaogan prescription. RESULTS AND CONCLUSION: The low-concentration Bushen Tiaogan prescription had no effect on embryo survival rate and hatching rate, while the high-concentration Bushen Tiaogan prescription could reduce embryo survival rate and hatching rate. Prednisolone, 25 µmol/L, was able to successfully induce significant loss of bone mass in zebrafish. Compared with the model group, 50, 100 and 250 mg/L Bushen Tiaogan prescription could resist prednisolone-induced zebrafish osteoporosis in a concentration-dependent manner. At low concentrations, there was no significant anti-osteoporosis effect, and at high concentrations, anti-osteoporosis effect showed a downward trend. These findings indicate that 25 µmol/L prednisolone successfully induces the establishment of zebrafish osteoporosis model, and successfully evaluates the initial safety of Bushen Tiaogan prescription. Bushen Tiaogan prescription begins to show an anti-osteoporosis effect at 50 mg/L, and has the most significant anti-osteoporosis effect at 250 mg/L.
