ABSTRACT
Diabetic nephropathy （DN）， a major cause of chronic kidney disease （CKD）， aggravates the prevalence of end-stage renal disease （ESRD） and threatens human health. The pathogenesis of DN is complex， in which inflammation is a key pathological link in the cascade injury. Therefore， the treatment targeting inflammation helps to delay the progression of DN. NOD-like receptor protein 3 （NLRP3）， a classical proteasome， acts as an inducer of innate immune responses. The activated NLRP3 inflammasomes produce and release inflammatory mediators to trigger pyroptosis and uncontrolled autophagy and mediate the stress signals promoting renal fibrosis， thus participating in the development and progression of DN. The NLRP3 inflammasome as a core site inducing inflammation is widely involved in DN progression and may be a novel target. The active components and compound prescriptions of Chinese medicines are increasingly applied in the prevention and treatment of DN. The latest studies have discovered that Chinese medicines can treat DN by regulating the activation of NLRP3 inflammasomes. Although studies have been conducted to explore the mechanism of Chinese medicines in the treatment of DN via NLRP3 inflammasome， the systematic review remains to be carried out. This paper reviews the relevant publications in recent years and introduces the research progress from the assembly and activation of NLRP3 inflammasomes， the mechanism of NLRP3 inflammasomes in the treatment of DN， and the regulation of NLRP3 inflammasomes by Chinese medicines for the prevention and treatment of DN， aiming to lay a foundation for the relevant studies and provide new targets and strategies for the prevention and treatment of DN.
ABSTRACT
Hepatic fibrosis （HF） is a widespread disease caused by various forms of chronic liver injury， significantly impacting human health. HF often has an insidious onset with inconspicuous symptoms， but in its advanced stages， it can progress to cirrhosis or even hepatocellular carcinoma. The pathogenic mechanisms of HF are highly complex， primarily characterized by excessive extracellular matrix （ECM） deposition. Autophagy is a lysosome-mediated degradation system employed by cells to recycle cellular contents， eliminate aggregated proteins， damaged organelles， and invading pathogens （such as viruses and bacteria） to maintain normal cellular function and dynamic balance. Autophagy can regulate various signaling pathways and factors， including mammalian target of rapamycin （mTOR）， adenosine monophosphate-activated protein kinase （AMPK）， and transforming growth factor-β （TGF-β）， to reduce the activation of hepatic stellate cells （HSCs） and hepatocyte necrosis and apoptosis， thereby mitigating ECM deposition and slowing the progression of HF. Numerous studies also suggest that traditional Chinese medicine （TCM） can effectively treat HF， and its mechanism of action may be related to autophagy. This article provides a review by summarizing recent literature in China and abroad on the mechanisms of autophagy， related signaling factors and pathways， as well as the role of TCM in regulating autophagy for the prevention and treatment of HF， aiming to offer insights and references for the development of TCM in the prevention and clinical rational medication in the treatment of HF.
ABSTRACT
ObjectiveTo study the clinical efficacy of the Qingre Lishi Huazhuo method on patients with chronic gouty arthritis of dampness-heat obstruction syndrome and the effect on nucleotide-binding oligomerization domain-like receptor 3（NLRP3）/interleukin-1β （IL-1β） signaling pathway to preliminarily explore its mechanism. MethodSixty patients with chronic gouty arthritis of dampness-heat obstruction syndrome were enrolled and divided into a treatment group （30 cases） and a control group （30 cases） according to the random number table method. Thirty people were assigned to the healthy group. Patients in the control group were treated with oral Febuxostat， while those in the treatment group were treated with modified Simiaosan combined with Febuxostat. Treatment lasted four weeks. The general clinical data， traditional Chinese medicine （TCM） syndrome scores， serum uric acid （UA）， serum creatinine （SCr）， blood urea nitrogen （BUN）， fasting blood glucose （FPG）， low-density lipoprotein （LDL）， triglyceride （TG）， total cholesterol （TC）， erythrocyte sedimentation rate （ESR）， and C-reactive protein （CRP） of patients were recorded. Enzyme-linked immunosorbent assay （ELISA） was employed to measure the levels of IL-1β，TNF-α， and IL-6，and the levels of NLRP3，cysteinyl aspartate-specific protease-1 （Caspase-1）， and apoptosis-associated speck-like protein containing a CARD （ASC） were detected by Western blot. ResultBefore treatment， the levels of body mass index （BMI）， systolic blood pressure （SBP），diastolic blood pressure （DBP），UA，SCr，BUN，FPG，LDL，TG，and TC in both groups significantly increased （P<0.05，P<0.01），and the levels of HDL significantly decreased as compared with those in the healthy group（P<0.05）. Additionally， the levels of IL-1β， TNF-α， and IL-6 in both groups significantly increased before treatment （P<0.01）. Compared with the results before treatment， patients in the two groups had significant reductions in tube pain， joint tenderness， joint swelling，joint fever， activity disorders， body fatigue， sliminess， bitter mouth， yellow and red urine， and tongue manifestation scores （P<0.05，P<0.01）. Compared with patients in the control group after treatment， those in the treatment group had a significant decrease in joint fever， body fatigue， sliminess， bitter mouth，sticky stool，yellow and red urine， tongue manifestation score， and pulse score （P<0.05）. The total effective rate in the treatment group was 80.0% （24/30）， higher than 56.7% （17/30）in the control group（χ2=11.916，P<0.05）. Compared with the results before treatment， BMI， SBP， DBP， UA， SCr， BUN， FPG， LDL， TG， TC， ESR，CRP， IL-1β， TNF-α， IL-6 levels， and VAS score in both groups significantly decreased （P<0.05，P<0.01）. Compared with patients in the control group after treatment， those in the treatment group had decreased DBP，ESR， IL-1β levels， and VAS score （P<0.05）. Western blot results showed that before treatment， the protein expression of NLRP3， Caspase-1， and ASC in peripheral blood mononuclear cells （PBMCs） of patients in both groups were higher than those in the healthy group （P<0.01）. Compared with the results before treatment， the protein expression of NLRP3， Caspase-1， and ASC in PBMCs in patients of both groups after treatment decreased （P<0.05，P<0.01）. Compared with the control group after treatment， the treatment group showed decreased expression levels of NLRP3 and Caspase-1（P<0.05）. ConclusionThe Qingre Lishi Huazhuo method can effectively improve the clinical symptoms and reduce inflammation of chronic gouty arthritis of dampness-heat obstruction syndrome with good safety. The mechanism may be related to the inhibition of the NLRP3/IL-1β signaling pathway.
ABSTRACT
Objective:To investigate the application of extracorporeal membrane oxygenation(ECMO)bridging heart transplantation in critically ill children.Methods:The clinical data of two cases of critical infants with venous-arterial ECMO(VA-ECMO)bridging heart transplantation and literature review were retrospectively analyzed.Results:Two cases received orthotopic heart allograft with VA-ECMO support, and were discharged uneventfully without significant postoperative complications.On the 13th day of ECMO assistance, the first child was treated with orthotopic heart transplantation in a hospital qualified for heart transplantation, and the ECMO was evacuated during the operation.After 21 days of the heart transplantation, the patient was discharged from the hospital.The patient was followed up to be healthy after heart transplantation, and had the same development as children of the same age, and had been taking anti-rejection drugs for a long time.On the 10th day of VA-ECMO treatment, the second case received awake ECMO after cardiac function improved.On the 12th day of VA-ECMO treatment, the patient was successfully evacuated from VA-ECMO and waited for heart transplantation.Cardiac orthotopic transplantation was performed after the 17 days after VA-ECMO evacuation.The patient was transferred to the general ward after 6 days of hospitalization in the intensive care unit, and was discharged 23 days after transplantation with conventional anti-rejection therapy.Discharge follow-up in good health, normal school life.Conclusion:When VA-ECMO cannot be withdrawn from the heart of the critically ill children and the end-stage heart, VA-ECMO bridging heart transplantation should be selected at the right time for the children who meet the indications for heart transplantation to create survival opportunity for the previously hopeless children, save the life of the end-stage children, and improve the quality of life.
ABSTRACT
Most critically ill children are in a state of severe stress and prone to malnutrition, which lead to a decline in the body′s resistance to disease and repair ability, thus aggravating the condition of children.After the initial support treatment of multiple organ functions, nutritional support should be considered as soon as possible to improve the metabolic status and supplement the metabolic needs of children, which can improve the nutritional status of children.Reasonable nutritional support treatment can not only improve nutritional status of the body, but also benefit the recovery and prognosis of the disease.Enteral nutrition is highly valued because it conforms to the gastrointestinal physiology and improves the mucosal barrier function of gastrointestinal tract.
ABSTRACT
Mutations of the X-linked methyl-CpG-binding protein 2 (MECP2) gene in humans are responsible for most cases of Rett syndrome (RTT), an X-linked progressive neurological disorder. While genome-wide screens in clinical trials have revealed several putative RTT-associated mutations in MECP2, their causal relevance regarding the functional regulation of MeCP2 at the etiologic sites at the protein level requires more evidence. In this study, we demonstrated that MeCP2 was dynamically modified by O-linked-β-N-acetylglucosamine (O-GlcNAc) at threonine 203 (T203), an etiologic site in RTT patients. Disruption of the O-GlcNAcylation of MeCP2 specifically at T203 impaired dendrite development and spine maturation in cultured hippocampal neurons, and disrupted neuronal migration, dendritic spine morphogenesis, and caused dysfunction of synaptic transmission in the developing and juvenile mouse cerebral cortex. Mechanistically, genetic disruption of O-GlcNAcylation at T203 on MeCP2 decreased the neuronal activity-induced induction of Bdnf transcription. Our study highlights the critical role of MeCP2 T203 O-GlcNAcylation in neural development and synaptic transmission potentially via brain-derived neurotrophic factor.

Objective:To investigate the clinical efficacy of wrist arthroscopic transosseous footprint repair technique for treating triangular fibrocartilage complex (TFCC) injury.Methods:A retrospective case series study was conducted to analyze the clinical data of 56 patients with TFCC injury admitted to Shenzhen Second People′s Hospital from July 2017 to September 2020, including 38 males and 18 females, aged 17-45 years [(33.5±3.6)years]. All patients had unilateral injury. Physical examination showed instability of the distal radioulnar joint, and MRI and arthroscopy confirmed deep ligament injury of TFCC. All patients underwent repair of deep insertion of the TFCC by using wrist arthroscopic transosseous footprint. The operation time, intraoperative blood loss, wound healing and postoperative complications were recorded. The flexion and extension range of motion of the wrist, radial and ulnal deviation of the wrist, rotation range of motion of the forearm, patient related wrist evaluation (PRWE) score, modified Mayo wrist score, visual analogue scale (VAS), and percentage of grip strength between the affected side and unaffected side were compared preoperatively, at 3 months postoperatively and at 1 year postoperatively.Results:All patients were followed up for 12-18 months [(13.4±5.2)months]. The operation time was (61.3±8.9)minutes, with the intraoperative blood loss of (2.4±1.2)ml. All wounds were healed by first intension. There was no wound infection or ulnar nerve irritation symptom after operation. Four patients experienced clicking on the ulnar side of the wrist in a short period of time post-operation, with spontaneous disappearance of the symptom. At 3 months postoperatively, the radial and ulnar deviation of the wrist was decreased from (52.5±5.9)° preoperatively to (42.6±5.9)°, and rotation range of motion of the forearm was decreased from (94.9±8.4)°preoperatively to (84.6±5.9)° (all P<0.01). The flexion and extension range of motion of the wrist was (93.1±17.4)° preoperatively, with insignificant difference compared with (89.4±5.8)° at 3 months postoperatively ( P>0.05). At 1 year postoperatively, the flexion and extension range of motion of the wrist, radial and ulnar deviation range of motion of the wrist, and rotation range of motion of the forearm were significantly increased to (101.3±13.6)°, (52.4±6.6)°, and (116.4±16.4)° when compared with those at 3 months postoperatively (all P<0.01). At 3 months postoperatively, the PRWE score was increased to (17.1±3.8)points from (10.6±3.2)points preoperatively ( P<0.01), modified Mayo wrist score was decreased to (70.3±6.7) points from (78.1±12.7)points preoperatively ( P<0.01), VAS was decreased to (4.4±1.7)points from (6.2±1.5)points preoperatively ( P>0.05), and percentage of grip strength between the affected side and unaffected side was decreased to (55.7±8.7)% from (74.4±15.2)% preoperatively ( P<0.01). At 1 year postoperatively, the PRWE score was increased to (2.0±0.9)points, modified Mayo wrist score was increased to (94.8±3.3)points, VAS was decreased to (2.1±1.1)points, and percentage of grip strength between the affected side and unaffected side was increased to (93.2±8.7)% when compared with those at 3 months postoperatively (all P<0.01). Conclusion:Wrist arthroscopic transosseous footprint repair technique can effectively treat deep ligament injury of TFCC, with advantages of significantly improving postoperative joint range of motion and functional score, relieving the pain on the ulnar side of the wrist and enhancing grip strength.
ABSTRACT
Objective:To summarize the experience of transthoracic epicardial insertion pacemaker for isolated congenital third-degree atrioventricular block (CAVB), and explore the necessity and feasibility of permanent pacemaker in the treatment of CAVB in neonates and infants.Methods:The clinical data and follow-up of four children with CAVB admitted to the Senior Department of Pediatrics, the Seventh Medical Center of PLA General Hospital from September 2010 to February 2022 were analyzed retrospectively.Two patients were implanted with permanent cardiac pacemakers during an early stage (less than one year old), and two patients were implanted during the non-early stage (one year old and above). All patients were diagnosed based on clinical symptoms, electrocardiogram and echocardiographic examination.After treatment, the pacing threshold, atrial sensing function, clinical symptoms, electrocardiogram and echocardiography examination of four patients were followed up.Results:All patients were successfully implanted with permanent cardiac pacemakers.One patient of non-early implantation was died of severe pneumonia and sepsis.During the follow-up period, pacing threshold, amplitude, impedance, minute ventilation and sensor function indicated pacemakers worked well in other three patients.Heart rates in these patients were significantly recovered, and showed growth trends in line with percentile curves for Chinese children and good movement skills.Conclusion:A pacemaker implantation performed by an experienced operator is a safe and feasible treatment for children with CAVB diagnosed in neonates and infants period with good prognosis.
ABSTRACT
OBJECTIVE@#To analyze the independent risk factors of long-term ischemic stroke and establish a nomogram for predicting the long-term risks in elderly patients with obstructive sleep apnea (OSA).@*METHODS@#This multicenter prospective cohort study was conducted from January, 2015 to October, 2017 among consecutive elderly patients (≥60 years) with newly diagnosed OSA without a history of cardio-cerebrovascular diseases and loss of important clinical indicators. The follow-up outcome was the occurrence of ischemic stroke. The baseline demographic and clinical data, sleep parameters, laboratory and ultrasound results were collected from all the patients, who were randomized into the modeling group (n=856) and validation group (n=258) at a 3∶1 ratio. LASSO regression was used for variable reduction and dimension screening, and the risk score prediction model of ischemic stroke was established based on Cox proportional hazard regression.@*RESULTS@#In the total of 1141 patients enrolled in this study, 58 (5.08%) patients experienced ischemic stroke during the median follow-up of 42 months (range 41-54 months). The cumulative incidence of ischemic stroke was 5.14% in the model group and 4.91% in the verification group (P < 0.05). Age (HR=3.44, 95% CI: 2.38- 7.77), fasting blood glucose (FPG) (HR=2.13, 95% CI: 1.22-3.72), internal diameter of the ascending aorta (HR=2.60, 95% CI: 1.0- 4.47), left atrial anteroposterior diameter (HR=1.98, 95% CI: 1.75-2.25) and minimum oxygen saturation (LSpO2) (HR=1.57, 95% CI: 1.20-1.93) were identified as independent risk factors for ischemic stroke (P < 0.05 or 0.01). A long-term ischemic stroke risk score model was constructed based the regression coefficient ratios of these 5 risk variables. Before and after the application of the Bootstrap method, the AUC of the cohort risk score model was 0.84 (95% CI: 0.78- 0.90) and 0.85 (95% CI: 0.78- 0.89) in the model group and was 0.83 (95% CI: 0.73-0.93) and 0.82 (95%CI: 0.72-0.90) in the verification group, respectively, suggesting a good prediction efficiency and high robustness of the model. At the best clinical cutoff point, the cumulative incidence of ischemic stroke was significantly higher in the high-risk group than in the low-risk group (P=0.021).@*CONCLUSION@#This model can help to identify high-risk OSA patients for early interventions of the risks of ischemic stroke associated with OSA.

Parkinson's disease (PD) is the second most common neurodegenerative disease, but none of the current treatments for PD can halt the progress of the disease due to the limited understanding of the pathogenesis. In PD development, the communication between the brain and the gastrointestinal system influenced by gut microbiota is known as microbiota-gut-brain axis. However, the explicit mechanisms of microbiota dysbiosis in PD development have not been well elucidated yet. FLZ, a novel squamosamide derivative, has been proved to be effective in many PD models and is undergoing the phase I clinical trial to treat PD in China. Moreover, our previous pharmacokinetic study revealed that gut microbiota could regulate the absorption of FLZ
ABSTRACT
Objective:In this study, a gait acquisition and analysis system is developed to provide a cheap, easy-to-use solution for quantitative recording and analysis of patients' gaits.Methods:From April 2017 to October 2018, we collected the gait data of 19 patients with knee osteoarthritis and 19 healthy volunteers in the orthopaedic outpatient department. Among 19 patients, there were 9 males and 10 females, aged 50.1±9.4 years old. Among 19 healthy volunteers, there were 8 males and 11 females, aged 50.7±10.3 years old. Then, from the collected gait data, the static gait features such as gait speed, step length, stride, and dynamic gait features were automatically calculated, and the statistical difference analysis was finished to determine the correlation between these quantitative gait features and knee osteoarthritis.Results:Firstly, the gait data collected by the depth camera was compared with the data from the multi infrared camera-based motion analysis system (gold standard). The average angle error of the collected knee joint angle was 0.98 degrees, which proved the correctness of the gait data recorded by the depth camera. The statistical difference analysis of gait characteristics between the patient group and the healthy group showed that the gait characteristics with P<0.05 included: gait speed ( r=-0.922, P<0.001), step length ( r=-0.897, P=0.004), stride ( r=-0.914 , P<0.001), dynamic characteristics of angle of knee joint ( r=0.775, P=0.001). Conclusion:The gait acquisition and analysis system based on the depth camera can accurately record and store the gait data of the patients with knee osteoarthritis. Moreover, the extracted quantitative gait features have statistical differences between the patients and the healthy group, which is helpful for the gait analysis of bone joint.
ABSTRACT
Objective:To analyze clinical factors related to nosocomial infection in children with extracorporeal membrane oxygenation(ECMO)support.Methods:General data, infection data and relevant factors in children with ECMO support in Bayi Children′s Hospital, the 7 th Medical Center of People′s Liberation Army General Hospital and Henan Provincial People′s Hospital from September 2012 to February 2020 were reviewed.Relevant factors of nosocomial infection in them were analyzed. Results:Among 163 cases, 36(22.1%) children supported with ECMO had infections during the period of ECMO, and 72 pathogenic microorganisms were detected, including 67 bacteria (33 Acinetobacter baumannii, 21 Klebsiella pneumoniae, and 6 Pseudomonas aeruginosa) and 5 fungi.Pathogens from the respiratory system, blood system, urinary tract and abdominal cavity were detected in 45 cases(62.5%), 25 cases (34.7%), 1 case (1.4%), and 1 case (1.4%), respectively.Drug sensitivity analysis of the Acinetobacter baumannii showed that it was the extensively resistant strain.Compared with uninfected children supported with ECMO, ECMO support time[(10.0±6.7) d], hospitalization[(34.0±25.3) d], hospitalization cost[(234 368±113 234) yuan], preoperative oxygenation index(52.8±23.0) and lactate value[(9.6±5.9) mmol/L]were significantly higher in nosocomial infection ones[(4.6±3.2) d, (24.3±19.8) d, (161 416±65 847) yuan, 35.6±10.4, (5.6±5.4) mmol/L] supported with ECMO (all P<0.05). There was no significant difference in the mortality between 2 groups ( P>0.05). In addition, lactate level (9.8 mmol/L) and oxygenation index (36.0±12.7) were significantly higher in died children(2.7 mmol/L, 22.1±10.4) with nosocomial infection during the period of ECMO support than those of survivors (all P<0.05). Multivariate Logistic regression analysis showed that ECMO support time( OR=7.054, 95% CI: 2.206-25.525) and preoperative lactate value( OR=2.250, 95% CI: 1.378-4.611) were independent risk factors of nosocomial infection. Conclusions:Correcting underlying diseases of ECMO supporting and shortening the duration of ECMO can reduce the incidence and mortality of nosocomial infection in children who are supported with ECMO.

ABSTRACT
To systematically review the efficacy of Xuebijing Injection combined with western medicine in the treatment of systemic inflammatory response syndrome(SIRS). In this study, CBM, CNKI, Wanfang, VIP, PubMed and EMbase databases were retrieved for clinical randomized controlled trials on the effect of Xuebijing Injection combined with western medicine in the treatment of SIRS from the establishment of the database to July 31, 2020. After screening, Meta-analysis was conducted by RevMan 5.3 software, trial sequential analysis was conducted by TSA 0.9.5.10 beta software, and the evidence quality level was evaluated by GRADEprofiler 3.6.1 software. Meta-analysis showed that Xuebijing Injection combined with western medicine could reduce white blood cell count(MD=-2.32, 95%CI[-2.44,-2.21], P<0.000 01), C-reactive protein count(MD=-22.70, 95%CI[-29.61,-15.79], P<0.000 01), APACHE Ⅱ score(MD=-2.15, 95%CI[-2.43,-1.87], P<0.000 01), tumor necrosis factor alpha count(SMD=-1.23, 95%CI[-1.48,-0.99], P<0.000 01) and interleukin-6 count(SMD=-0.92, 95%CI[-1.15,-0.69], P<0.000 01), improve treatment efficiency(RR=1.39, 95%CI[1.23, 1.56], P<0.000 01), reduce incidence of multiple organ dysfunction(RR=0.47, 95%CI[0.35, 0.64], P<0.000 01) and mortality(RR=0.22, 95%CI[0.13, 0.37], P<0.000 01), which were better than western medicine treatment alone. Trial sequential analysis showed that in terms of reducing the incidence of multiple organ dysfunction and C-reactive protein count, the cumulative Z value passed through the traditional threshold, TSA threshold and expected information value, and reached the required number of cases. GRADE evaluation showed that the level of evidence was low or very low. According to the findings, Xuebijing Injection combined with western medicine is effective in treating SIRS. However, as the low quality of the included studies may affect the reliability of the conclusion, more high-quality studies shall be included for further verification in the future, so as to provide better suggestions for clinical medication.

The Montreux definition established in 2017 made it clear that the neonates can not be excluded from the diagnosis of acute respiratory distress syndrome (ARDS), which supported the urge of emphasizing the specificity and importance of neonatal ARDS (nARDS) in the past ten years in China. Neonatal idiopathic respiratory distress syndrome is caused primarily by insufficient pulmonary surfactant system, which pathologically and clinically presented as typical respiratory distress syndrome. While the causes of nARDS often coexisted with underlying conditions, and its pathological and clinical features are a superposition of both respiratory distress syndrome and underlying conditions. Therefore, superimposition is the key to understanding the etiology, pathology, diagnosis, and treatment of nARDS, which is crucial for optimizing the clinical practice of nARDS.
ABSTRACT
Objective:To investigate the difference of curative effect between zero-profile bridge-shaped locking cage (ROI-C) and anterior cage combined with titanium plate fixation in the treatment of two-level and three-level cervical spondylotic myelopathy.Methods:A total of 85 patients (43 males and 42 females), aged 52.3±8.0 years (range from 28 to 66 years) with bi- and three-level cervical spondylotic myelopathy who received surgical treatment from June 2017 to October 2019 were retrospectively analyzed. There were 63 cases of two levels and 22 cases of three levels. 45 cases were treated with zero-profile bridge-shaped locking cage ROI-C (ROI-C group), and 40 cases with anterior cage combined with titanium plate fixation (titanium plate group). The main observation indicators include operation time, intraoperative blood loss, cervical Cobb angle, fusion segment Cobb angle, average intervertebral height, pain visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) Score and neck disability index (NDI).Results:All of 85 patients were followed up for 16.9±2.0 months (range 12 to 22 months). The operation time of two-level ROI-C group was 110.37±8.25 min, which was shorter than 139.5±10.54 min of titanium plate group; the intraoperative blood loss was 15.74±8.10 ml, which was less than 23.71±9.70 ml of titanium plate group; the operation time of three-level ROI-C group was 130.00±5.70 min, which was shorter than 162.83±5.59 min of titanium plate group, while the difference in the intraoperative blood loss between the two groups had no statistical significance. One year after operation, Cobb angle of cervical vertebra in double and three-level ROI-C groups were 15.31°±1.55° and 15.20°±0.42°, respectively, which were largerthan 11.23°±2.03° and 9.20°±1.14° before operation; in titanium plate group, they were 15.89°±1.13° and 16.08°±1.88°, which were higher than 11.25°±2.01° and 9.00°±1.60° before operation, and the differences had statistical significance. The differences between the two groups before operation and 1 year after operation had no statistical significance. One year after operation, the VAS scores of double and three-level ROI-C groups were 1.83±0.66 points and 2.60±0.52 points, respectively, which were less than the preoperative 7.49±0.51 points and 7.60±0.52 points; the titanium plate group was 1.79±0.50 points and 2.41±0.51 points, which were less than the preoperative 7.61±0.63 points and 7.42±0.52 points, and the differences had statistical significance. There was no significant difference between the two groups before operation and 1 year after operation. One year after operation, the JOA scores of double and three-level ROI-C groups were 15.00±0.84 points and 14.70±0.95 points, respectively, which were higher than the preoperative 7.20±0.87 points and 6.60±1.27 points; the scores of titanium plate group were 15.29±0.85 points and 14.83±0.58 points, which were higher than the preoperative 6.89±1.03 points and 6.92±0.67 points, and the differences had statistical significance. The differences between the two groups had no statistical significance. The postoperative JOA improvement rate was excellent. Postoperative dysphagia occurred in 1 case (2.22%, 1/45) in ROI-C group and 8 cases (20.00%, 8/40) in titanium plate group, and the difference in the incidence rate between two groups had statistical significance ( χ2=5.32, P=0.02). Conclusion:Both ROI-C and anterior cage combined with titanium plate fixation in the treatment of double and three-level cervical spondylotic myelopathy can achieve good short-term clinical efficacy, with shorter operation time and lower incidence rate of postoperative dysphagia using ROI-C.
ABSTRACT
In order to achieve the overall victory of the 2019 novel coronavirus disease epidemic in this 'war’, especially to prevent the disease recurrence from rebounding during the resumption of labor, the government has not loosened any control of personnel mobility, which has obviously affected the normal examination and treatment of lung cancer patients under the influence of this epidemic. During the epidemic period, cancer patients with low immunity levels face the double ordeals of disease and epidemic situation. Compared with the general population, they are more likely to be infected with the new coronavirus. Among the infected cancer patients, lung cancer is the most common type. It is necessary to provide more appropriate individualized treatment recommendations for patients with lung cancer based on the epidemic situation of the patient's location and in combination with the patient's own condition. Through active prevention of infection, timely conversion of treatment strategies, online and offline joint control, and positive psychological counseling, we significantly hope to help patients with lung cancer to survive this difficult period.
ABSTRACT
OBJECTIVE@#A3 intertrochanteric fracture is an extremely unstable fracture, which is often treated with intramedullary nail, but the implant failure is common due to the posterior medial fragment cannot be reconstructed. A new medial sustainable nail (MSN-Ⅱ) which can reconstruct the femoral medial support by sustainable screw was introduced in this study. The mechanical effect was verified by biomechanical experiment.@*METHODS@#The loss medial support model of intertrochanteric fracture (A3) was made by artificial Sawbones model, fixed with MSN-Ⅱ and PFNA-Ⅱ, underwent axial loading and axial failure tests. The axial stiffness, yield load, displacement of head-neck fragment and torsional angle of fracture site of these nails were recorded and compared for biomechanical differences. The effect of early reconstruction of medial support with MSN-Ⅱ was determined.@*RESULTS@#The axial stiffness, yield load, the displacement of head and neck fragment when the axial load was 1 800 N and torsional angle of the fracture site after the axial failure test of MSN-Ⅱ were (222.76 ±62.46) N /mm, (4 241.71 ±847.42) N, (11.51 ±0.62) mm, (1.71 ±0.10)° respectively, while the PFNA -Ⅱ was (184.58±40.59) N /mm, (3 058.76±379.63) N, (16.15±1.36) mm, (2.52±0.26)°respectively. The difference between the two groups was statistically significant.@*CONCLUSION@#The axial stiffness of MSN-Ⅱ is better than that of PFNA-Ⅱ. The MSN-Ⅱ can bear more loads when fixed A3.3 intertrochanteric fracture and has greater axial and rotational stability. It is an effective means to reconstruct the medial support of A3 intertrochanteric fracture.

ABSTRACT
BACKGROUND@#Catheter ablation is effective in restoring sinus rhythm and left atrial appendage closure (LAAC) is increasingly used for stroke prevention in patients with atrial fibrillation (AF). We aimed to observe the feasibility and safety of performing AF ablation and LAAC in a single (one-stop) procedure.@*METHODS@#Consecutive AF patients who underwent the combined procedure of AF ablation and LAAC with WATCHMAN device between March 2017 and September 2018 were prospectively enrolled. Baseline and intra-procedural parameters were evaluated. Three-month and subsequent 1-year follow-up were performed in all and earlier-enrolled subjects, respectively.@*RESULTS@#A total of 178 AF patients (94 males, 68.9 ± 8.1 years) underwent the one-stop procedure with CHA2DS2-VASc score 3.3 ± 1.5 and HAS-BLED score 1.6 ± 1.0, respectively. Pulmonary vein isolation was achieved in all patients while additional linear ablation was applied if the operator deemed necessary, yielding immediate ablation success rate of 98.9% (176/178). In the subsequent LAAC, satisfactory seal (residual leak <5 mm) was achieved in all patients. One stroke and four cardiac perforations occurred peri-operatively. At 3-month follow-up, sinus rhythm and satisfactory seal were maintained in 153/178 (86.0%) and 178/178 (100%) patients, respectively. One stroke and one delayed cardiac tamponade occurred, while no device-related thrombus or device migration was observed. During the 1-year follow-up for the earlier enrolled subjects, 52/72 (72.2%) of the patients maintained sinus rhythm. There was no stroke or systemic embolism observed.@*CONCLUSION@#Combining catheter ablation and LAAC in a single procedure can be successfully and safely performed in non-valvular AF patients of Chinese population.
