ABSTRACT
The theory of disease prevention with traditional Chinese medicine is introduced into the prevention of chronic diseases such as hypertension. In order to fully implement the advantages of acupuncture, the three-level prevention strategy is strengthened on the whole-process intervention with acupuncture for hypertension, including prevention before disease onset, starting intervention at the early phase, and prevention disease from exacerbating. Moreover, the comprehensive management scheme, multidisciplinary coordination and participation mechanism are investigated in the field of traditional Chinese medicine for preventive treatment of hypertension.

Lung volume reduction loop uses bronchoscopic lung volume reduction(BLVR) technology to compress and collapse the necrotic emphysema tissue and exhaust the internal gas to achieve the purpose of lung volume reduction to treat emphysema. After the lung volume reduction loop is implanted into the human body, the compressed part of the lung tissue tends to expand with breathing, which makes the lung volume reduction loop expand into a linear trend periodically. Fatigue resistance is one of the most important performance indexes of the lung volume reduction loop. In the paper, Z-direction vibration fatigue machine was used to simulate the changes of human respiratory cycle movement to test the fatigue performance of lung volume reduction loop, which can provide some reference for the test method of in vitro fatigue performance of lung volume reduction related products in the future.

Objective:To observe the effect of microelectronic EMG bridge (EMGB) training on the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury. Methods:From March, 2016 to March, 2017, 20 patients with complete cervical 5 spinal cord injury were randomly divided into control group (n = 10) and experimental group (n = 10). The control group received routine wrist extensor muscle training, and the experimental group received EMGB training in addition, for 180 days. The motor function of the affected limb was evaluated by sEMG of extensor carpi radialis longus, Manual Muscle Test (MMT), Wolf Motor Function Test (WMFT) and Spinal Cord Lesion Independence Measure (SCIM). Results:After treatment, the peak value and average value of sEMG of extensor carpi longus of both sides increased in both groups (t > 2.510, P < 0.05), the peak value and average value of the left side were higher (t > 2.759, P < 0.05), and the peak value of the right side was higher (t = 2.691, P < 0.05) in the experiment group than in the control group, however, there was no significant difference in average value of the right side between two groups (t = 2.063, P = 0.054). The scores of MMT increased in both groups (t > 2.569, P < 0.05), and were higher in the experimental group than in the control group (t > 2.278, P < 0.05). The scores of WMFT and SCIM increased in both groups (t > 3.839, P < 0.05), however, there was no significant difference between two groups (t < 1.498, P > 0.05). Conclusion:EMGB training could improve the motor function of extensor carpi radialis longus in patients with complete cervical 5 spinal cord injury.
ABSTRACT
A chemical investigation on the fermentation products of Sanghuangporus sanghuang led to the isolation and identification of fourteen secondary metabolites (1-14) including eight sesquiterpenoids (1-8) and six polyphenols (9-14). Compounds 1-3 were sesquiterpenes with new structures which were elucidated based on NMR spectroscopy, high resolution mass spectrometry (HRMS) and electronic circular dichroism (ECD) data. All the isolates were tested for their stimulation effects on glucose uptake in insulin-resistant HepG2 cells, and cellular antioxidant activity. Compounds 9-12 were subjected to molecular docking experiment to primarily evaluate their anti-coronavirus (SARS-CoV-2) activity. As a result, compounds 9-12 were found to increase the glucose uptake of insulin-resistant HepG2 cells by 18.1%, 62.7%, 33.7% and 21.4% at the dose of 50 μmol·L

Objective To explore the candidate genes that play significant roles in the interconnection between abdominal aortic aneurysm (AAA) and type 2 diabetes mellitus (DM). Methods We used the Biomedical Discovery Support System (BITOLA) to screen out the candidate intermediate molecular (CIM) "Gene or Gene Product" that are related to AAA and DM. The dataset of GSE13760, GSE7084, GSE57691, GSE47472 were used to analyze the differentially expressed genes (DEGs) of AAA and DM compared to the healthy status. We used the online tool of Venny 2.1 assisted by manual checking to identify the overlapped DEGs with the CIMs. The Human eFP Browser was applied to examine the tissue specific expression levels of the detected genes in order to recognize strong expressed genes in both human artery and pancreatic tissue. Results There were 86 CIMs suggested by the closed BITOLA system. Among all the DEGs of AAA and DM, 8 genes in GSE7084 (ISG20, ITGAX, DSTN, CCL5, CCR5, AGTR1, CD19, CD44) and 2 genes in GSE13760 (PSMD12, FAS) were found to be overlapped with the 86 CIMs. By manual checking and comparing with tissue-specific gene data through Human eFP Browser, the gene PSMD12 (proteasome 26S subunit, non-ATPase 12) was recognized to be strongly expressed in both the aorta and pancreatic tissue. Conclusion We proposed a hypothesis through text mining that PSMD12 might be involved or potentially involved in the interconnection between AAA and DM, which may provide a new clue for studies on novel therapeutic strategies for the two diseases.
ABSTRACT
Objective To observe the effect of edaravone on endogenous neural stem cells in rats with permanent cerebral ischemia. Methods The rat model of permanent cerebral ischemia was established by electrocoagulation. Thirty SD rats were randomly divided into three groups; sham operation group, brain injury group and edaravone group. Six hours after the establishment of the model, the edaravone group was intraperitoneally injected with 1.5 g/L edaravone (10 ml/kg) once a day. The sham operation group and the cerebral ischemia group were intraperitoneally injected with saline of equal volume for 7 days. 24 hours after the last administration, BrdU positive cells, Nestin/BrdU positive cells, neuronal class III β-tubulin (Tuj1)/BrdU positive cells and glial fibrillary acidic protein (GFAP)/BrdU positive cells were observed by immunofluorescent staining, Tuj1 and GFAP protein expressions were detected by Western blotting. Results Compared with the cerebral ischemia group, the BrdU positive cells, Nestin/BrdU positive cells, Tuj1/BrdU positive cells and GFAP/BrdU positive cells increased significantly in the infraventricular area and the cortex area around the ischemia in the edaravone group (P<0.05). Compared with the cerebral ischemia group, the expression of Tuj1 and GFAP protein in the cerebral cortex of edaravone group increased ( P<0.05). Conclusion Edaravone can promote the proliferation of endogenous neural stem cells and astrocytes in the subventricular area and the cortex around ischemia, and promote the differentiation of endogenous neural stem cells into neurons.
ABSTRACT
Spinal injuries caused by competitive sports are common. Spinal diseases are important issues that needs to be solved urgently in the fields of sports injury. Return to play recommendations are complicated due to a mix of medical factors, social pressures, and limited outcome data. This article reviewed the current situation of athletes return to play after spine and spinal cord injury based on disease classification, including cervical spine (cervical soft tissue injuries, cervical fracture and dislocation, cervical stenosis, cervical disk herniation, stingers and burners), thoracic spine (thoracic fracture), lumbar spine (lumbar strain, lumbar stenosis spondylolysis and spondylolisthesis, lumbar disk herniation), and spinal cord concussion and spinal cord injury. This article also analyzed the criteria for athletes to return to play after spine and spinal cord injuries. It may provide references for future clinical management and consensus/guidelines.
ABSTRACT
Objective:To analyze the characteristics of athletes' sports injuries during the Winter Olympic and Winter Youth Olympic Games. Methods:The information of registered athletes during the 2010, 2014 Winter Olympics and 2012 Winter Youth Olympic Games, including the injury numbers of each sport, damage sites, types and severity of injuries were collected, and the epidemiological characteristics were analyzed. Results:A total of 6370 person-time registered athletes were collected and 789 sports injuries were recorded. The injury rate per 1000 registered athletes was 123.9. An average of 11% of athletes was injured at least once. There was a significant difference in the injury rate among these events (χ2 = 12.301, P = 0.002). Women were more likely to be injured than men (χ2 = 5.220, P = 0.022). The top three sports with the highest injury rate were snowboarding (23.9%), freestyle skiing (23.2%) and Bobsleigh (18.0%); the top three sports with the largest number of injuries were ice hockey (160 person-time, 20.3%), alpine skiing (128 person-time, 16.2%) and snowboarding (113 person-time, 14.3%). The top three most injured sites were knee (54 person-time, 13.6%), head (41 person-time, 10.3%) and lumbar spine/lower back (27 person-time, 6.8%); the top three types of injury were contusion/haematoma/bruise (123 person-time, 30.9%), sprain (dislocation/subluxation or ligamentous rupture) (71 person-time, 17.8%) and strain (muscle rupture/tear or tendon rupture) (47 person-time,11.8%). A total of 251 injuries (31.8%) were expected to result in time loss for the athlete, 81 out of whom were severe injuries (32.3%). Conclusion:There is a mass of sport injuries in winter sports events with different types and severities. The incidence of injury varies with sports, and it is focused on snowboarding, freestyle skiing and Bobsleigh, ice hockey and alpine skiing. It is needed to research the technical characteristics of specific sports, damage risk factors and mechanism to reduce the sports injuries, and to construct green channels for sports injuries, to promote the recovery of function.
ABSTRACT
The incidence and proportion of traumatic spinal cord injury in the elderly are increasing year by year, and it has become the main affected population of spinal cord injury in developed countries. Fall is the main cause of injury. The increase of spinal stenosis, the biomechanical changes of the spine and the hyperextension injuries may be the mechanism of spinal cord injury caused by minor trauma in this population. Traumatic spinal cord injury in the elderly usually requires early surgical treatment. When there are complicated comorbidities, unstable vital signs or mild spinal cord injury without major fracture or dislocation, non-surgical treatment and active rehabilitation can be considered. However, the specific indications and timing of surgery are still controversial. Compared with young people, most elderly patients present with incomplete cervical spinal cord injury and are expected to restore better limb function, following poor recovery of self-care ability. It is important to monitor the functional change throughout rehabilitation and adjust the hours and intensity of training accordingly.
ABSTRACT
BACKGROUND@#There are an increasing number of patients with oral sensory complaints (OSCs) presenting to our dental clinic. For most dentists, it is difficult to distinguish burning mouth syndrome (BMS) from other oral mucosal diseases that may cause symptoms such as burning mouth. It is beneficial to effectively distinguish OSC patients to reduce misdiagnosis and eliminate burning symptoms as much as possible.@*METHODS@#Patients with oral burning sensations in the oral mucosal disease clinic were collected from the Peking University Hospital of Stomatology between September 1, 2014 and December 31, 2018. After excluding oral candidiasis, anemic stomatitis, dental material allergy, and other diseases from patients with oral sensory complaints, basic conditions such as gender, age, education level, job status, hyperglycemia, hypertension, hyperlipidemia, history of brain abnormalities, history of cervical spondylitis, history of thyroid disease, history of thyroid disease and insomnia were obtained. The BMS patients were compared with the control group. The t test and Chi-square test were used for statistical analysis to compare the clinical symptoms of these diseases and explore the risk factors for BMS.@*RESULTS@#In this case-control study, 395 patients (321 females and 74 males, mean age 55.26 ± 10.51 years) with oral sensory complaints and 391 healthy controls (281 females and 110 males, mean age 47.11 ± 13.10 years) were enrolled, among which, 8.4% (33/395) had oral candidiasis, 1.3% (5/395) had dental material allergy, 0.8% (3/395) had anemic stomatitis and 0.5% (2/395) had lichen planus. A total of 352 patients were eventually diagnosed with BMS. Anxiety and depression were more severe in BMS patients, as were the incidences of sleep disorders and brain abnormalities. Logistic regression analysis showed that age (odds ratio [OR] = 2.79, 95% confidence interval [CI]: 1.61-4.83, P < 0.001), total cholesterol level (OR = 2.92, 95% CI: 1.32-6.50, P = 0.009) and anxiety score (OR = 1.75, 95% CI: 1.01-2.77, P = 0.017) significantly increased the incidence of BMS. Patients with hyperglycemia (OR = 0.46, 95% CI: 0.23-0.89, P = 0.022), low body mass index (BMI: OR = 0.57, 95% CI: 0.34-0.93, P = 0.026) and low education level (OR = 3.43, 95% CI: 1.91-6.15, P < 0.001) were more likely to suffer from BMS.@*CONCLUSIONS@#Oral candidiasis, anemic stomatitis, and dental material allergy with burning symptoms should be excluded from patients with BMS. It is recommended to conduct a questionnaire survey (including anxiety and depression), blood cell analysis, and salivary fungus culture for all patients with an oral burning sensation. It is necessary to conduct a patch test on patients with oral burning sensations and metal restorations.

BACKGROUND@#Blood glucose control is closely related to type 2 diabetes mellitus (T2DM) prognosis. This multicenter study aimed to investigate blood glucose control among patients with insulin-treated T2DM in North China and explore the application value of combining an elastic network (EN) with a machine-learning algorithm to predict glycemic control.@*METHODS@#Basic information, biochemical indices, and diabetes-related data were collected via questionnaire from 2787 consecutive participants recruited from 27 centers in six cities between January 2016 and December 2017. An EN regression was used to address variable collinearity. Then, three common machine learning algorithms (random forest [RF], support vector machine [SVM], and back propagation artificial neural network [BP-ANN]) were used to simulate and predict blood glucose status. Additionally, a stepwise logistic regression was performed to compare the machine learning models.@*RESULTS@#The well-controlled blood glucose rate was 45.82% in North China. The multivariable analysis found that hypertension history, atherosclerotic cardiovascular disease history, exercise, and total cholesterol were protective factors in glycosylated hemoglobin (HbA1c) control, while central adiposity, family history, T2DM duration, complications, insulin dose, blood pressure, and hypertension were risk factors for elevated HbA1c. Before the dimensional reduction in the EN, the areas under the curve of RF, SVM, and BP were 0.73, 0.61, and 0.70, respectively, while these figures increased to 0.75, 0.72, and 0.72, respectively, after dimensional reduction. Moreover, the EN and machine learning models had higher sensitivity and accuracy than the logistic regression models (the sensitivity and accuracy of logistic were 0.52 and 0.56; RF: 0.79, 0.70; SVM: 0.84, 0.73; BP-ANN: 0.78, 0.73, respectively).@*CONCLUSIONS@#More than half of T2DM patients in North China had poor glycemic control and were at a higher risk of developing diabetic complications. The EN and machine learning algorithms are alternative choices, in addition to the traditional logistic model, for building predictive models of blood glucose control in patients with T2DM.
ABSTRACT
Objective:To study the regularity of clinical symptoms of sympathetic cervical spondylosis. Methods:A retrospective study was conducted on 110 patients with sympathetic cervical spondylosis admitted to the outpatient department from 2017 to 2019. The regularity of clinical symptoms of the patients was analyzed, including the sympathetic symptoms of different systems, the property of dizziness, the sequence, time interval and correlation of the symptoms, and whether the numbness of the limbs was accompanied by the symptoms and signs of cervical spondylotic radiculopathy and cervical spondylotic myelopathy. Results:The sympathetic symptoms were complex, involved in digestive system (71.82%), cardiovascular system (83.64%), respiratory system (63.64%), sweat gland (48.18%), eyes (81.82%), ears (60.91%), brain (68.18%) and limbs (70%), mainly sympathetic excitatory. The dizziness of the patients was mainly manifested as muddled brain (66.36%), a few patients were accompanied by external objects or their own rotation and sloshing (23.64%), and a very few patients showed external objects or their own rotation and sloshing (8.18%). Most patients complained chronic neck pain before dizziness and other sympathetic symptoms, accounting for 58.18%. The mean time for progression from neck pain to dizziness was (68.98±64.42) months. There were 77 patients complaining limb numbness, but none of them was found symptoms or signs of cervical spondylotic radiculopathy or cervical spondylotic myelopathy. It seemed to be a part of sympathetic symptoms in the limbs. The severity of dizziness was positively correlated with the course of disease (r = 0.610, P < 0.001), and was also positively correlated with the score of sympathetic symptom (r = 0.301, P = 0.004). Conclusion:The symptoms of sympathetic cervical spondylosis are complex. Muddled brain is the main symptom of dizziness, not vertigo. As the disease progresses, dizziness and sympathetic symptoms gradually worsen. Most sympathetic cervical spondylosis develops from cervical spondylosis. Cervical spondylotic radiculopathy or cervical spondylotic myelopathy may be the more severe forms of cervical spondylosis that develop on this basis。
ABSTRACT
Metabolic syndrome characterized by obesity, hyperglycemia and liver steatosis is becoming prevalent all over the world. Herein, a water insoluble polysaccharide (WIP) was isolated and identified from the sclerotium of Poria cocos, a widely used Traditional Chinese Medicine. WIP was confirmed to be a (1-3)-β-D-glucan with an average Mw of 4.486 × 10 Da by NMR and SEC-RI-MALLS analyses. Furthermore, oral treatment with WIP from P. cocos significantly improved glucose and lipid metabolism and alleviated hepatic steatosis in ob/ob mice. 16S DNA sequencing analysis of cecum content from WIP-treated mice indicated the increase of butyrate-producing bacteria Lachnospiracea, Clostridium. It was also observed that WIP treatment elevated the level of butyrate in gut, improved the gut mucosal integrity and activated the intestinal PPAR-γ pathway. Fecal transplantation experiments definitely confirmed the causative role of gut microbiota in mediating the benefits of WIP. It is the first report that the water insoluble polysaccharide from the sclerotium of P. cocos modulates gut microbiota to improve hyperglycemia and hyperlipidemia. Thereby, WIP from P. cocos, as a prebiotic, has the potential for the prevention or cure of metabolic diseases and may elucidate new mechanism for the efficacies of this traditional herbal medicine on the regulation of lipid and glucose metabolism.

@#Objective To retrospectively analyze the features and related factors of deep venous thrombosis(DVT)in patients with traumatic paraplegia during early rehabilitation. Methods Inpatients of our hospital from June,2014 to June,2017 were included and patients with traumatic paraplegia during early rehabilitation were analyzed.The clinical information,lower limbs deep vein ultrasonic testing and laboratory examination were collected to analyze features and related factors of DVT. Results A total of 269 patients with traumatic paraplegia during early rehabilitation were analyzed and 62 patients had DVT in lower limbs(23.0%),in which 50 patients had an isolated distal DVT and 28 cases occurred in bilateral lower limbs(45.2%).No patients younger than 14 had DVT in lower limbs(n=31).Logistic regression analysis showed that increased D-dimer (OR=1.348, 95% CI 1.193~1.525), advanced age (OR=3.450, 95% CI 1.372~8.674),male(OR=2.872,95% CI 1.095~7.533)and diabetes(OR=5.319,95% CI 1.094~25.872)were indepen-dent related factors for DVT. Conclusion The incidence of DVT in lower limbs of traumatic paraplegia patients during early rehabilitation is high. DVT develops mainly distally to the popliteal vein and bilaterally of lower limbs. Prepubertal children have a low incidence of DVT.Increased D-dimer,advanced age,male and diabetes are independent related factors for DVT.
ABSTRACT
Objective To further explore the complication of spinal cord injury occured after transcatheter arterial chemoemboliza-tion(TACE)for hepatocellular carcinoma via inferior phrenic artery. Methods The clinical and imaging data of one patient with spinal cord injury caused by TACE for hepatocellular carci-noma via inferior phrenic artery was retrospectively analyzed.The pathologic mechanism,risk factors and out-come of rehabilitative treatment were discussed after literature review. Results The abnormal opening of communicating branches between inferior phrenic artery and spinal cord blood supply-ing was the underlying mechanism inducing spinal cord injury after TACE. The risk factors included contrast agent,chemotherapy drug,embolic agent,and multiple interventional therapy,etc.Most patients returned almost to normal state within several months after early rehabilitation. Conclusion Spinal cord injury occurred after TACE for hepatocellular carcinoma via inferior phrenic artery is an ex-tremely rare complication.Most patients have a favorable outcome with early detection and timely rehabilitation.
ABSTRACT
<p><b>OBJECTIVE</b>To explore the proangiogenic activity of exsomes released by human umbilical cord mesenchymal stem cells (MSCs) stimulated by erythropoietin and platelet-derived growth factor BB (PDGF-BB).</p><p><b>METHODS</b>Human umbilical cord-derived MSCs were seeded and maintained in culture overnight. The media were then replaced by alpha-MEM containing EPO (1 U/ml) and/or PDGF-BB (50 ng/ml), and the culture was maintained for 72 hours. The exosomes from the culture supernatants were isolated with a routine ultra-catrifagation method. Flow cytometric analysis was performed to identify the origin of the exosomes, and their morphological features were observed by using a transmission electron microscopy. The exosomes were added at a concentration of 10 µg/ml into the culture system of human umbilical cord vein endothelial cells. MTT assay was used to evaluate the proliferative status. The Matrigel assay was used to observe the formation of net-work structures which were calculated after culture for 12 hours.</p><p><b>RESULTS</b>Flow cytometric analysis showed that microparticles released by human umbilical cord MSCs expressed CD9, CD63 and CD81, which was in accordance with the surface molecular features of exosomes. Under an electron microscope, the exosomes took the featured cystic shape. The protein contents of exosomes released by untreated, EPO-stimulated, PDGF-BB-stimulated and EPO plus PDGF-BB stimulated MSCs (10 cells) were 256±124 µg, 1021±392 µg, 830±265 µg and 2207±733 µg, respectively. The results revealed that MSCs treated by EPO and PDGF-BB released significantly higher amounts of exosomes (P<0.01). MTT assay proved that the exosomes from EPO and PDGF-BB treated MSCs had more potent proliferation-promoting activity on human umbilical cord vein endothelial cells than those from untreated MSCs. The Matrigel assay showed that the numbers of capillary-like structures in untreated, EPO-, PDGF-BB and EPO plus PDGF-BB-treated groups were 2.6±0.84, 4.6±1.57, 4.2±0.78 and 6.3±1.34 per high power objective. Treatment with EPO or PDGF-BB dramatically enhanced the numbers of capillary liue structure, compared with that of untreated group (P<0.01) and those in EPO and PDGF-BB combination group was significantly greater than those of EPO or PDGF-BB group (P<0.01).</p><p><b>CONCLUSION</b>EPO and PDGF-BB can stimulate MSCs to release exosomes with more potent proangiogenic activity.</p>

OBJECTIVE: To investigate the causes for failed anterior cervical surgery and the outcomes of secondary laminoplasty. METHODS: Seventeen patients failed anterior multilevel cervical surgery and the following conservative treatments between Feb 2003 and May 2011 underwent secondary laminoplasty. Outcomes were evaluated by the Japanese Orthopaedic Association (JOA) Scale and visual analogue scale (VAS) before the secondary surgery, at 1 week, 2 months, 6 months, and the final visit. Cervical alignment, causes for revision and complications were also assessed. RESULTS: With a mean follow-up of 29.7+/-12.1 months, JOA score, recovery rate and excellent to good rate improved significantly at 2 months (p0.05). Mean VAS score decreased postoperatively (p0.05). The causes for secondary surgery were inappropriate approach in 3 patients, insufficient decompression in 4 patients, adjacent degeneration in 2 patients, and disease progression in 8 patients. Complications included one case of C5 palsy, axial pain and cerebrospinal fluid leakage, respectively. CONCLUSION: Laminoplasty has satisfactory results in failed multilevel anterior surgery, with a low incidence of complications.

<p><b>OBJECTIVE</b>To investigate the clinical outcomes of semicircular decompression in treating old thoracolumbar fractures and intractable neuropathic pain.</p><p><b>METHODS</b>From September 2009 to September 2013, 21 patients with old thoracolumbar fracture and intractable neuropathic pain were treated with semicircular decompression. Among initial surgery, posterior pedicle screw fixation was used in these patients, with or without laminectomy. All patients were male, range in age from 20 to 28 years old with an average of (25.00±2.38) years. Vertebral body residual bone block resulted in intra-spinal placeholder more than 50%. All patients were complete spinal cord injury (ASIA grade) or cauda equina injury. VAS scores was from 6 to 10 points with the mean of 7.14±0.91. In these patients, MRI, CT, X-rays were performed; denomination and dosage of analgesics were recorded; nerve function and pain status were respectively evaluated by ASIA grade and VAS score before and after operation.</p><p><b>RESULTS</b>All patients were followed up from 8 to 32 months with an average of (17.29±6.02) months. All bone fragments of spinal canal were removed and spinal cord decompressions were achieved. At final follow-up, VAS scores were from 0 to 8 points with an average of (2.43±2.46) points, and were obviously reduced than peroperative data (P<0.05). Eleven cases of them stopped analgesic intake and 7 cases reduced using. Three patients' symptoms and VAS scores were not improved.</p><p><b>CONCLUSION</b>Old thoracolumbar fractures and intractable neuropathic pain need receive imaging examination as soon as possible and consider semicircular decompression therapy if bone fragments were in vertebral canal and spinal canal stenosis existed. This therapy can effectively relieve pain and profit nerve functional recovery.</p>
