Objective:To discuss the regulatory effect of berberine(BBR)on fatty acids in the human glioma T98G cells and its effect on the cell proliferation,migration,and invasion,and to clarify its potential mechanism.Methods:The T98G cells at logarithmic growth phase were divided into control group and different concentrations(25,50,and 100 mg·L-1)of BBR groups.Cell wound healing assay was used to detect the migration rates of the cells in various groups;Transwell chamber assay was used to detect the invasion rates of the cells in various groups.The T98G cells at logarithmic growth phase were divided into control group and 100 mg·L-1 BBR group,and Mass spectrometry was used to detect the fatty acid contents in the cells in two groups.The T98G cells at logarithmic growth phase were divided into control group and different concentrations(50,100,and 150 mg·L-1)of BBR groups;Western blotting method was used to detect the expression levels of phosphatidylinositol 3-kinase(PI3K),phosphorylated PI3K(p-PI3K),protein kinase B(AKT),phosphorylated AKT(p-AKT),sterol regulatory element-binding protein 1(SREBP-1),and fatty acid synthase(FASN)in the cells in various groups.The expression of FASN was suppressed by gene silencing technology,and the T98G cells at logarithmic growth phase were divided into control group,shFASN1 group,and shFASN2 group.Western blotting method was used to detect the expression levels of FASN protein in the cells in various groups;clone formation assay was used to detect the clone formation of the cells in various groups;cell wound healing assay was used to detect the migration rates of the cells in various groups.Results:Compared with control group,the migration rates and invasion rates of the cells in different concentrations of BBR groups were decreased in a concentration-dependent manner(P<0.01),and the fatty acid content in the cells in 100 mg·L-1 BBR group was significantly decreased(P<0.01).Compared with control group,the expression levels of p-PI3K,p-AKT,SREBP-1,and FASN proteins in the cells in 150 mg·L-1 BBR group were significantly decreased(P<0.05 or P<0.01),and the expression level of SREBP-1 protein in the cells in 100 and 150 mg·L-1 BBR groups were significantly decreased(P<0.01).After suppression of FASN expression,compared with control group,the expression levels of FASN protein in the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the expression level of FASN protein in the cells in shFASN2 group was lower than that in shFASN1 group(P<0.05);compared with control group,the numbers of clone formation and migration rates of the cells in shFASN1 and shFASN2 groups were significantly decreased(P<0.01),and the migration rate of the cells in shFASN2 group was significantly lower than that in shFASN1 group(P<0.05).Conclusion:BBR interferes with fatty acid synthesis in the glioma T98G cells by reducing the expression of the PI3K/AKT/SREBP-1/FASN pathway related proteins,and decrease their migration and invasion capabilities.

To summarize the experience of Professor WANG Qingguo in diagnosing and treating wind-cold-dampness arthralgia based on the principle that "the nutrient-defense qi does not merge with wind-cold-dampness qi， so it did not result to arthralgia". By analyzing the relationship between nutrient-defense qi and wind-cold-dampness arthralgia， it is believed that the occurrence of wind-cold-dampness arthralgia is closely related to the movement of nutrient qi and defense qi， and the key to the treatment of this disease is to regulate nutrient qi and defense qi and remove the combination of nutrient-defense qi and wind-cold-dampness qi. The core pathogenesis of wind-cold-dampness arthralgia in the early stage is the initial combination of nutrient-defense qi and wind-cold-dampness qi， and the treatment should harmonize nutrient-defense qi and eliminate the pathogen and release pathogenesis， with Chaihu Guizhi Decoction （柴胡桂枝汤） as the main prescription； the core pathogenesis of the middle stage is nutrient-defense qi and wind-cold-dampness qi cemented together， and the treatment should harmonize and tonify nutrient qi and defense qi and separate the pathogen to alleviate disease， with self-prescribed Chuanteng Tongbi Decoction （穿藤通痹汤） as the main prescription； the core pathogenesis of the late stage is deficiency and stagnation of nutrient-defense qi， wind-cold-dampness qi still exist， and the treatment should tonify and free nutrient qi and defense qi to eliminate pathogen and arthralgia， with self-prescribed Chuanqing Haijia Decoction （穿青海甲汤） plus Duhuo Jisheng Decoction （独活寄生汤） as the main prescription.

Objective:To explore the impact of clinical features, serological indicators, and pulmonary function test (PFT) on the prognosis of rheumatoid arthritis-associated interstitial lung disease (RA-ILD).Methods:Clinical data of RA-ILD patients who were diagnosed by HRCT and were followed up in Changhai Hospital or Yancheng First People's Hospital from 2011 to 2021 were collected Respiratory functional impairment of the patients was evaluated according to the changes of HRCT score and PFT, and the patients were divided into progressive group and stable group. COX survival analysis and ROC curve were used to determine the factors related to the progression of RA-ILD.Results:Finally 98 RA-ILD patients were included. The mean age of ILD onset was (62.9±12.1) years old, the median course of RA was 7.0 (1.0, 15.3)years, and the median follow-up time was 36.5 months (14.0, 79.5). There were 49 cases in the progressive group, and the clinical characteristics and laboratory tests of the two groups were compared. The results showed that: progressive time [(23(8.5,43.0)months vs 63(32.5,90.9) months, Z=-4.55, P=0.001)], HRCT score [(115(109,135) vs 111(105,116), Z=-2.70, P=0.007)], forced vital capacity(FVC) predicted [(70.1±15.7)% vs (80.8±19.7)%, t=2.12, P=0.039)], diffusing capacity of the lungs for CO(DLCO) predicted [(57.5±16.3)% vs (83.4±18.8)%, t=4.87, P=0.001)], male [(44.9% vs 18.4%, χ2=7.97, P=0.005)], UIP pattern [(36(73.5%) vs 9(18.4%), χ2=29.96, P<0.001)], RF>200 U/ml[(21(65.6%) vs 18(41.9%), χ2=4.15, P=0.042)], anti-CCP>75 U/ml [(42(91.3%) vs 35(71.4%), χ2=6.10, P=0.013], all had significantly different between the two groups. In multivariate analyses, UIP[ HR(95% CI)=3.25(1.62,6.50), P<0.001], anti-CCP antibody >75 U/ ml[ HR(95% CI)=3.85 (1.20,12.33), P=0.023] and smoking [ HR (95% CI): 5.74(1.10, 30.13), P=0.039] were significantly correlated with the progression of pulmonary fibrosis in RA-ILD patients. PFT was performed in only 44 patients with RA-ILD. The univariate analyses and ROC curve suggested that DLCO predicted [ HR (95% CI)=1.04 (1.02,1.06), P<0.001] was a significant risk factor for the progression of RA-ILD, and the area under curve (AUC) of DLCO was 0.845 [95% CI=(0.729,0.961)]. Conclusion:UIP pattern, high titer of anti-CCP antibody, smoking, and reduced DLCO predicted % may be potential predictors for poor prognosis of RA-ILD patients.

Objective:To investigate the safety and efficacy of short-segment fixation covering the fractured vertebrae via posterior intermuscular approach plus percutaneous kyphoplasty (PKP) through the outer upper edge of the base of the fractured vertebral pedicle in the treatment of osteoporotic thoracolumbar burst fracture.Methods:A retrospective case series study was used to analyze the clinical data of 56 patients with osteoporotic thoracolumbar burst fracture admitted to Ningbo No.6 Hospital from January 2018 to February 2021, including 24 males and 32 females; aged 56-72 years [(63.5±4.6)years]. All patients underwent short-segment fixation covering the fractured vertebrae via posterior intermuscular approach combined with PKP through the outer upper edge of the base of the fractured vertebral pedicle. The operation time, intraoperative blood loss, hospitalization day and surgery-related complications were recorded. The visual analogue score (VAS) of back pain, ratios of the anterior, middle and posterior height of the fractured vertebrae and kyphotic Cobb angle were compared before operation, at postoperative 2 days and at the final follow-up.Results:All patients were followed up for 12-28 months [(14.5±2.2)months]. The operation time was 55-85 minutes [(62.0±12.1)minutes], intraoperative blood loss was 80-150 ml [(94.0±18.5)ml], and hospitalization day was 5-9 days [(7.4±1.1)days]. Based on CT examination at postoperative 2 days, there were 2 patients with paravertebral cement leakage, 2 with intervertebral space leakage and 1 with intracanal leakage, but none reported associated clinical symptoms. No implant failure or fractures of adjacent segments was detected during the follow-up period. The VAS was significantly decreased from preoperative (7.5±1.2)points to (3.2±0.8)points at postoperative 2 days ( P<0.01), and the score was further lowered to (2.2±0.8)points at the final follow-up when compared with that at postoperative 2 days ( P<0.01). The ratios of the anterior, middle and posterior height of the fractured vertebrae and kyphotic Cobb angle were significantly improved at postoperative 2 days [(89.5±13.2)%, (85.8±7.9)%, (89.5±9.0)% and (5.6±3.2)°] when compared with those before operation [(48.9±11.8)%, (61.9±11.9)%, (79.9±9.8)% and (26.3±5.6)°] (all P<0.01). Slight losses were observed in the ratios of the anterior, middle and posterior height of the fractured vertebrae and kyphotic Cobb angle at the final follow-up [(87.0±12.7)%, (82.1±7.8)%, (88.6±10.0)% and (5.4±3.2)°], but not significantly different from those at postoperative 2 days (all P>0.05). Conclusion:Short-segment fixation covering the fractured vertebrae via posterior intermuscular approach plus PKP through the outer upper edge of the base of the fractured vertebral pedicle can safely and effectively treat osteoporotic thoracolumbar burst fracture, for it can significantly improve back pain, restore the height of the fractured vertebrae and correct the kyphotic deformity.

Stroke rescue features strong time sensitivity and high complexity. Minimizing the time of consumption in pre-hospital and in-hospital stroke rescue is key to improve stroke rescue efficiency and reduce the disability rate. In December 2017, a tertiary hospital launched the construction of a one-stop stroke rescue platform. This platform was centered on " multi-mode image fusion operating room" , operating as a one-stop rescue mode integrating emergency admission, imaging examination, intravenous thrombolytic therapy, mechanical thrombolytic therapy, postoperative evaluation, and so on. The seamless convergence workflow of pre-hospital, in-hospital and post-hospital could effectively optimize the physical rescue pathway. In order to ensure the efficient and orderly operation of the platform, the hospital adopted such measures as multidisciplinary integration, pre-hospital and in-hospital integration construction, and regional stroke care network. Since its operation in September 2019, the platform has treated more than 1 000 patients by December 2021. The application of the platform had effectively improved the efficiency of stroke rescue, led the development of regional stroke rescue system, and provided the reference for raising the stroke rescue capacity and management level in China.

Objective:To evaluate the efficacy of scalp nerve block combined with general anesthesia in optimizing anesthesia in the patients with moyamoya disease undergoing revascularization.Methods:A total of 154 patients with moyamoya disease, aged 18-64 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective revascularization, were divided into 2 groups ( n=77 each) using a random nunber table method: scalp nerve block combined with general anesthesia group (GN group) and general anaesthesia group (G group). Anesthesia was induced with intravenous midazolam 0.05 mg/kg, sufentanil 0.5-1.0 μg/kg, rocuronium 0.6 mg/kg and etomidate 0.2-0.3 mg/kg.After the patients were tracheally intubated after anesthesia induction, ipsilateral scalp nerve block (2 ml for supraorbital nerve block, 2 ml for supratrochlear nerve block; 3 ml for auriculotemporal nerve block, 3 ml for greater occipital nerve block, 3 ml for less occipital nerve block) was performed with 0.5% ropivacaine in GN group.The equal volume of normal saline was locally injected in G group.Anesthesia was maintained by inhalation of sevoflurane and intravenous infusion of remifentanil 0.05-0.10 μg·kg -1·min -1 and cisatracurium 0.1 mg·kg -1·h -1.The consumption of intraoperative remifentanil, requirement for postoperative rescue analgesia, nausea and vomiting, length of postoperative hospital stay, and early neurological complications were recorded.The modified Rankin Scale scores were evaluated before operation, at discharge and at 6 months after operation. Results:Compared with G group, the consumption of intraoperative remifentanil and requirement for postoperative rescue analgesia were significantly decreased ( P<0.05), and no significant change was found in the incidence of postoperative nausea and vomiting, incidence of neurological complications, length of postoperative hospital stay, and modified Rankin Scale scores at each time point in GN group ( P>0.05). Conclusions:Scalp nerve block combined with general anesthesia can increase the perioperative analgesic efficacy and is helpful in achieving a low-opioid anesthesia mode when used in the patients with moyamoya disease undergoing revascularization.

Objective To explore the biomechanical properties of posterior occipital condyle screws compared with common occipitocervical fusion internal fixation and it's impacts upon stress of hypoglossal canals.Methods Finite element models based on the occipitocervical CT data of one 28-year-old male healthy volunteer were built,including normal model,instability model,internal fixation model by occipital condyle screws,internal fixation model by occipital plate screws,and internal fixation model by transarticular screws.Fifty N gravity and 1.5 N · m torque were exerted upon the surface of occipital bone so that the models could perform lateral bending,flexion,extension,and rotational motions.The motion range and stress distribution of internal fixation were compared under varying conditions among different occipitocervical fusion models.In addition,the impact of occipital condyle screw upon hypoglossal canals was examined.Results Compared with instability model,the motion range in the internal fixation model by occipital condyle screws declined by 96.8％,95.6％,95.0％ and 98.5％ respectively in lateral bending,flexion,extension and rotation.In the internal fixation by occipital plate screws,the motion range decreased by 96.3％,95.7％,98.4％ and 99.6％ respectively.In the internal fixation by transarticular screws,the motion range exhibited a decline of 95.7％,94.0％,94.3％ and 98.9％,respectively.The stress peaks in the occipital condyle screw were 192.4 MPa,201.6 MPa and 187.6 MPa under lateral bending,flexion,and rotation conditions,respectively.The stress peaks in the occipital plate screw were 279.6 MPa,213.7 MPa,and 154.1 MPa,respectively.The stress peaks in the transarticular screw were 232.4 MPa,220.9 MPa,and 224.5 MPa,respectively.The stress impact peak of occipital condyle screw on the hypoglossal canals wall was 12.96 MPa,and the content deformationunder the hypoglossal canal was 0.64％.Conclusions The occipital condyle screw internal fixation has similar stability with common occipitocervical fusion fixations.The occipital condyle screw has more uniform stress distribution and less effect on the hypoglossal canals,and hence is safe and reliable as anchor point on the cranial side in occipitocervical fusion.

Objective To assess the effects of axial spinous process-muscle-vascellum complex transplantation for posterior atlantoarial fusion.Methods Data of 27 cases with altantoarial disease who were treated by posterior atlantoarial fusion using axial spinous process-muscle-vascellum complex transplantation from June 2015 to June 2016 were retrospectively analyzed.There were 19 males and 8 females aged from 9 to 68 years old (mean,41.0±15.4 years old).Two cases were diagnosed with atlanto-axial instability.Fourteen cases were diagnosed with atlas fracture and eleven cases were diagnosed atlanto-axial fracture.All the 27 patients suffered from neck pain or limitations of cervical motion.All patients were assessed clinically by atlantoaxial reduction and bone graft fusion.The pre-operative and post-operative atlanto-dens interval (ADI),visual analogue scale (VAS),Japanese Orthopaedic Association scores (JOA),improvement rate of JOA score and axial symptoms were measured and statistically analyzed.Complications were recorded.Clinical outcome of latest follow-up was evaluated by X-ray and CT scan.Results The time of operation was 2.0-2.5 h and blood loss was 150-300 ml.All the patients were followed-up for 9 to 18 months (mean,11.5±2.1 months).The VAS of neck pain improved from 3.6±2.7 (range,2.0-5.0) pre-operatively to 1.4±0.2 (range,0-2.0) 12 months postoperatively (P=0.000).The JOA score improved from 11.7± 1.9 (range,10.0-15.0) pre-operatively to 15.3±0.6 (range,14.0-17.0)12 months post-operatively (P=0.000).The improvement rate of JOA score at the latest follow-up was 54.1％± 12.4％,including 23 cases (85.19％) excellent,and 4 cases (14.81％) good.The results of axial symptoms were no-symptom in 22 cases (81.48％) and mild symptoms in 5 cases (18.52％).Postoperative cervical spine X-ray and CT showed that the sagittal cervical spine alignment was restored.There was statistically significant difference between ADI of 4.3±1.1 mm (range,3.9-4.5 mm) pre-operatively to 2.5± 0.4 mm (range,2.1-2.6 mm) 12 months post-operatively,which was improved significantly (P=0.000).There were no complications found during the follow-up.Conclusion The application of axial spinous process-muscle-vascellum complex transplantation for posterior atlantoaxial fixation can preserve the dynamic function of muscles and reduce the postoperative pain,as well as avoid donor site morbidity.
