Knockdown of ACC1 promotes migration of esophageal cancer cell / 中华肿瘤杂志

Objective: To investigate the effect of acetyl-CoA carboxylase 1 (ACC1) knockdown on the migration of esophageal squamous cell carcinoma (ESCC) KYSE-450 cell and underlying mechanism. Methods: Lentiviral transfection was conducted to establish sh-NC control cell and ACC1 knocking down cell (sh-ACC1). Human siRNA HSP27 and control were transfected by Lipo2000 to get si-HSP27 and si-NC. The selective acetyltransferase P300/CBP inhibitor C646 was used to inhibit histone acetylation and DMSO was used as vehicle control. Transwell assay was performed to detect cell migration. The expression of HSP27 mRNA was examined by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR) and the expressions of ACC1, H3K9ac, HSP27 and epithelial-mesenchymal transition-related proteins E-cadherin and Vimentin were detected by western blot. Results: The expression level of ACC1 in sh-NC group was higher than that in sh-ACC1 group (P<0.01). The number of cell migration in sh-NC group was (159.00±24.38), lower than (361.80±26.81) in sh-ACC1 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC group were statistically significant compared with sh-AAC1 group (P<0.05). The migrated cell number in sh-NC+ si-NC group was (189.20±16.02), lower than (371.60±38.40) in sh-ACC1+ si-NC group (P<0.01). The migrated cell number in sh-NC+ si-NC group was higher than that in sh-NC+ si-HSP27 group (152.40±24.30, P<0.01), and the migrated cell number in sh-ACC1+ si-NC group was higher than that in sh-ACC1+ si-HSP27 group (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-NC+ si-NC group were significantly different from those in sh-ACC1+ si-NC and sh-NC+ si-HSP27 groups (P<0.01). The protein expression levels of E-cadherin and Vimentin in sh-ACC1+ si-NC group were significantly different from those in sh-ACC1+ si-HSP27 group (P<0.01). After 24 h treatment with C646 at 20 μmmo/L, the migrated cell number in sh-NC+ DMSO group was (190.80±11.95), lower than (395.80±17.10) in sh-ACC1+ DMSO group (P<0.01). The migrated cell number in sh-NC+ DMSO group was lower than that in sh-NC+ C646 group (256.20±23.32, P<0.01). The migrated cell number in sh-ACC1+ DMSO group was higher than that in sh-ACC1+ C646 group (87.80±11.23, P<0.01). The protein expressions of H3K9ac, HSP27, E-cadherin and Vimentin in sh-NC+ DMSO group were significantly different from those in sh-ACC1+ DMSO group and sh-NC+ C646 group (P<0.01). The protein expression levels of H3K9ac, HSP27, E-cadherin and Vimentin in sh-ACC1+ DMSO group were significantly different from those in sh-ACC1+ C646 group (P<0.01). Conclusion: Knockdown of ACC1 promotes the migration of KYSE-450 cell by up-regulating HSP27 and increasing histone acetylation.

Research progress of soluble growth stimulating gene 2 protein in cardiovascular disease / 中国基层医药

Growth stimulating gene 2 (ST2) protein is a member of the interleukin-1 receptor family. It is mainly divided into a soluble secreted form sST2 and a transmembrane form ST2L. sST2 is a decoy receptor that competitively binds to interleukin-33 to block the interleukin-33/ST2L signaling pathway, worsening myocardial hypertrophy, fibrosis, and ventricular dysfunction. Measuring sST2 is of important value for diagnosis and/or prognosis evaluation of cardiovascular diseases. This paper mainly reviews the research progress in the relationship between cardiovascular diseases such as heart failure, coronary heart disease, hypertension, atrial fibrillation, myocarditis, cardiomyopathy, acute aortic dissection, and pulmonary hypertension, and sST2.

Application of self-developed rapid tracheotomy apparatus for acute tracheotomy / 中国基层医药

Objective:To investigate the application effects of self-developed rapid tracheotomy apparatus for acute tracheotomy.Methods:A total of 120 patients who underwent an acute tracheotomy in the Weihai Branch of The 970 Hospital of PLA Joint Logistics Support Force from January 2019 to December 2020 were included in this study. These patients were randomly divided into a rapid group and a conventional group, with 60 patients in each group. Patients in the rapid group underwent tracheotomy with a self-developed rapid tracheotomy apparatus. Patients in the conventional group underwent the standard steps of traditional tracheostomy. The operation time, incision length, amount of bleeding, and incidence of postoperative complications were compared between the two groups.Results:The operation time in the rapid group was significantly shorter than that in the conventional group [(4.5 ± 0.9) minutes vs. (19.3 ± 4.7) minutes, t = 23.86, P < 0.001]. The length of incision in the rapid group was significantly shorter than that in the conventional group [(2.8 ± 0.3) cm vs. (4.2 ± 1.3) cm, t = 8.68, P < 0.001]. The amount of bleeding during the surgery in the rapid group was significantly less than that in the conventional group [(4.4 ± 1.6) mL vs. (11.8 ± 4.1) mL, t = 12.99, P < 0.001]. The incidence of postoperative complications in the rapid group was significantly lower than that in the conventional group ( χ2 = 4.66, P = 0.031). Conclusion:The self-developed rapid tracheotomy apparatus for acute tracheotomy can be used to establish an artificial airway quickly and minimally invasively by simplifying the operational steps.

Relationship between interleukin-1β and silicosis development / 中国基层医药

Silicosis is a diffuse pulmonary fibrosis disease caused by occupational exposure to silica, which is one of the occupational diseases with high incidence in developing countries. Up to now, there is no definite drug to relieve or reverse the lung injury caused by silicosis, so it is very important to prevent, diagnose and treat pulmonary fibrosis as soon as possible. Studies have shown that a chronic inflammatory environment contributes to pulmonary fibrosis to a certain extent. Interleukin-1β is a cytokine that increases the number of inflammatory factors in the microenvironment in the immune response and plays a key role in inflammatory reaction. Therefore, the release of interleukin-1β is of great significance in the pathogenesis of silicosis. This paper aims to systematically expound the development course of silicosis, the signal pathway of interleukin-1β production, and the relationship between them.

Expanded Applications of Traditional Chinese Medicine Four Examination Techniques in Asymptomatic Spleen-Stomach Diseases / 中医杂志

Asymptomatic spleen-stomach diseases refer to diseases without related symptoms and signs of abdo-minal pain， bloating， diarrhea an others in patients， but showing lesions or pathological changes discovered by modern medical techniques such as endoscopy， CT， MRI. The four examination techniques of traditional Chinese medicine （TCM） are based on symptoms and signs of patients， which are the advantage of TCM but also have certain limitations. In the context of the increasingly modernized diagnosis and treatment in TCM， it is proposed to expand the application of the four examination techniques from three aspects including microcosmic syndrome differentiation， data sharing， and artificial intelligence in asymptomatic spleen-stomach diseases， in order to achieve the goals of dynamically observing the disease process， collecting disease data in multiple dimensions， and intelligently processing disease data. This will strengthen the modern requirements of early diagnosis and treatment in TCM， and highlight the advantages of TCM in “treating disease before it arises and treating the symptoms beforehand”.

Fatty Acid Binding Protein 5 (FABP5) Promotes Aggressiveness of Gastric Cancer Through Modulation of Tumor Immunity

Purpose@#Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. @*Materials and Methods@#We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). @*Results@#Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokinecytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. @*Conclusions@#These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

Effect of intermittent theta burst transcranial magnetic stimulation on non-fluent aphasia after stroke / 中国康复理论与实践

ObjectiveTo explore the therapeutic effect and mechanism of intermittent theta burst transcranial magnetic stimulation (iTBS) on non-fluent aphasia after stroke. MethodsFrom August, 2021 to August, 2022, 50 patients with non-fluent aphasia after stroke in the First People's Hospital of Lianyungang were randomly divided into sham stimulation group (n = 25) and iTBS group (n = 25). Both groups accepted speach training. iTBS group accepted iTBS, and the sham stimulation group received sham iTBS, for four weeks. The serum brain-derived neurotrophic factor (BDNF) was measured, and they were assessed by China Rehabilitation Research Center Standard Aphasia Examination (CRRCAE) and Boston Diagnostic Aphasia Examination before and after treatment. ResultsTwo cases in the sham stimulation group and three cases in iTBS group dropped down. The BDNF level, and listen and understand, repeat, name, read aloud, and total score of CRRCAE improved in two groups after treatment (|t| > 5.012, P < 0.001); and they were better in iTBS group than in the sham stimulation group (|t| > 3.968, P < 0.001). The total effective rate was more in iTBS group than in the sham stimulation group (χ2 = 8.835, P < 0.05). ConclusioniTBS can improve speech function in patients with non-fluent aphasia after stroke, which may associate with the promotion of BDNF.

Clinical effects and pathological characteristics of gastric tumors of fundic gland type treated with endoscopic submucosal dissection / 中华消化内镜杂志

To evaluate the clinical effects and pathological characteristics of gastric tumors of fundic gland type treated with endoscopic submucosal dissection (ESD), data of 7 patients who treated by ESD and whose postoperative pathology indicated gastric adenocarcinoma of fundic gland type or gastric oxyntic gland adenoma in Endoscopic Center of Beijing Chao-Yang Hospital of Capital Medical University from August 2018 to June 2022 were collected. The clinical characteristics, surgical complications, preoperative and postoperative pathological data and follow-up data were evaluated. The lesions of the 7 patients were all located at gastric fundus, and were treated by ESD successfully. No bleeding, perforation or other complications occurred during and after the operation. Postoperative pathology showed that tumor cells originated from deep mucosa with an invasive growth pattern. Most of tumor surfaces were covered with normal concave epithelium. Tumors infiltrated into submucosa in 4 patients, and submucosa infiltration depth was more than 500 μm (550 μm) in 1 patient. Immunohistochemistry showed that MUC-6 was diffusely positive, indicating that the tumor originated from the main cell source. The expressions of MUC-2, MUC-5AC, CDX-2, CD10, and CgA were negative in all cases. With the mean follow-up time of 21 months, the ulcer healed well after the operation, with no recurrence. Gastric tumors of fundic gland type have relatively unique biological characteristics, and ESD is the preferred treatment. In addition, the histological characteristics can be used to differentiate from other gastric tumors by immunohistochemistry.

Clinical outcomes of selecting the vertebra above sagittal stable vertebra as distal fusion level for Scheuermann's thoracic kyphosis / 中华骨科杂志

Objective:To investigate the clinical outcome and complications associated with utilizing sagittal plane stable vertebra-1 (SSV-1) as the distal instrumented vertebra (LIV) in posterior fusion of thoracic kyphosis with Scheuermann's Disease kyphosis (STK).Methods:A longitudinal study on patients with STK who underwent posterior correction and fusion surgery from January 2018 to June 2021 were conducted. All participants had a follow-up duration over two years. Patients were divided into two groups according to the segment of LIV: the SSV group, where LIV was located in SSV; and the SSV-1 group, where LIV was located in the vertebral body above SSV. The radiographic parameters, including global kyphosis (GK), lumbar lordosis (LL), and sagittal plane (SVA), LIV offset distance (LIV translation), pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS), were compared between the two groups. The SRS-22 scale was used to evaluate health-related quality of life at pre-operation and last follow-up, and the incidence of postoperative distal junctional kyphosis (DJK) was also recorded. Analytical techniques, such as Analysis of Variance and Mann-Whitney tests, were employed to compare inter-group differences.Results:A total of 57 patients were included in the study, 36 in the SSV group and 21 in the SSV-1 group. The average age for patients were 16.1±2.3 years (range 13-20 years), and the average follow-up time was 32.8±6.8 months (range 24-53 months). There were no statistically significant differences between the two groups in terms of gender, age, follow-up time, surgical time, intraoperative bleeding volume, and fusion level. Before surgery, the LIV deviation distance in the SSV group was significantly lower than that in the SSV-1 group (-7.9±11.0 mm vs. 31.5±11.5 mm, t=7.64, P<0.001). In the SSV group, the preoperative GK was 79.3°±10.5°, and the last follow-up GK was 44.4°±8.5°, which was significantly improved compared to preoperative value ( t=28.28, P<0.001); in the SSV-1 group, the preoperative GK was 81.1°±10.6°, and the value at 1-week post-operative was 44.9°±7.8°, which was significantly improved compared to pre-operative value ( t=22.23, P<0.001). At the last follow-up, it was 45.1°±8.7°, with a correction rate of 44.3%±8.5%. No significant difference was observed between the two groups in terms of GK, LL, SVA, PI, PT and SS at pre-operative, 1-week post-operative and last follow-up ( P>0.05). All patients had no intraoperative complications of nerve injury. During the follow-up period, one patient (1/21, 4.8%) developed DJK without complications such as proximal kyphosis, pseudarthrosis, or failed internal fixation. At the last follow-up, the functional score of SRS-22 in SSV-1 group improved from preoperative (3.5±0.54) to postoperative (4.1±0.62), with an average improvement rate of 19.2%±3.2%, and the difference was statistically significant ( t=3.74, P=0.001). These results indicating that the surgical treatment was effective in relieving the symptoms of the patients. Conclusion:Selecting SSV-1 as LIV in corrective surgeries for STK appears to produce commendable clinical results with minimal implant-associated complications over a two-year observation period.

The utilization of second sacral alar-iliac screw fixation technique in the treatment of adult spinal deformity: analysis of risk factors for postoperative sagittal imbalance / 中华骨科杂志

Objective:To evaluate the clinical outcomes and complications of second sacral alar-iliac (S 2AI) technique utilized in degenerative spinal deformity patients, and to analyze the potential risk factors for postoperative sagittal imbalance. Methods:From January 2014 to October 2020, a consecutive cohort of 39 degenerative spinal deformity patients who were treated with S 2AI were retrospectively reviewed, including 4 males and 35 females, aged 63.1±6.7 years (range, 43-73 years). All of the patients had a minimum of 2-year follow-up. According to the sagittal vertical axis (SVA) at the final follow-up, patients were divided into 2 groups. Sagittal balance group (SVA≤50 mm) and sagittal imbalance group (SVA>50 mm). Radiographic parameters including the Cobb's angle, coronal balance distance (CBD), thoracic kyphosis (TK), lumbar lordosis (LL), SVA, pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS) were measured in the standing radiographs before and after operation and at the latest follow up. Comparison was made between the two groups and the differences with statistical significance were analyzed with binary logistic regression analysis. Intraoperative and postoperative complications were recorded. The Scoliosis Research Society-22 (SRS-22) score were employed to evaluate the quality of life. Results:The average follow-up period was 30.3±9.1 months (range, 43-73 months). Eighteen patients (46%) were identified with sagittal imbalance at the last follow-up. Compared with the patients in the sagittal balance group, the preoperative SVA was significantly larger (83.1±56.2 mm vs. 48.1±51.1 mm, t=2.04, P=0.049) and the postoperative TK was significantly greater (27.8°±9.6° vs. 18.9°±13.4°, t=2.36, P=0.024) for patients in the sagittal imbalance group. Scores of pain domain (3.2±0.5 vs. 3.7±0.6) and self-image domain (3.4±0.8 vs. 3.8±0.6) in sagittal imbalance group were significantly lower than those of sagittal balance group ( P<0.05). Logistic regression analysis showed that larger preoperative SVA ( OR=1.02, P=0.028) and greater postoperative TK ( OR=1.09, P=0.022) were independent risk factors for the occurrence of sagittal imbalance during the follow-up periods. Conclusion:S 2AI screw fixation can achieve satisfying coronal deformity correction and great sagittal reconstruction after surgery in patients with degenerative spinal deformity. However, sagittal imbalance may still occur during the follow-up periods. Larger preoperative SVA and greater postoperative TK are independent risk factors for the occurrence of sagittal imbalance.

Prevalence and distribution of ossification of ligamentum flavum at the adjacent segment of the apex in patients with degenerative kyphosis / 中华骨科杂志

Objective:To evaluate the prevalence and distribution of ossification of ligamentum flavum (OLF) at the segments adjacent to the apex in patients with degenerative kyphosis.Methods:All of 74 patients with degenerative kyphosis from January 2018 to December 2021 were retrospective reviewed. All patients were taken anteroposterior and lateral radiographs, CT scan and magnetic resonance imaging (MRI) of the entire spine. Global kyphosis, the morphology of kyphosis and the occurrence of OLF at three segments adjacent to the kyphosis apex were recorded.Results:Of the 74 patients, 54 patients (73%) developed OLF in three segments adjacent to the kyphotic apex. The mean age of the 54 patients was 61.4±6.8 years, and the mean global kyphosis was 49.5°±21.2°. Among other 20 patients without OLF, the mean age was 56.1±7.5 years, and the mean kyphosis angle was 52.1°±19.1°. There was a statistically significant difference in ages ( t=2.92, P=0.005), but no statistically significant difference was observed regarding global kyphosis ( t=0.48, P=0.634). In these 74 patients, 9 patients had angular kyphosis, of which 8 (89%) developed OLF; of the 65 patients without angular kyphosis, 46 patients (71%) developed OLF. There was no significant difference between them (χ 2=1.32, P=0.251). Among the 54 patients diagnosed with OLF, 5 patients (9%) suffered ossification of the posterior longitudinal ligament (OPLL) and 20 patients (37%) suffered dural ossification; 43 patients (80%) developed OLF at proximal segments of apex, 6 patient (11%) developed OLF at distal segments of apex, and 5 patients (9%) developed OLF both at proximal and distal segments of apex. Thirty-two patients (59%) developed OLF at the first segment adjacent to the kyphotic apex, 27 patients (50%) developed OLF at the second segment, and 15 patients (28%) developed OLF at the third segment. Conclusion:Among patients with degenerative kyphosis, about 73% may development OLF within three segments adjacent to the kyphotic apex, and it mostly occurred within two segments adjacent to the apex proximally.

The late-onset spine deformity in patients underwent myelomeningocele repair: radiologic characteristic and surgical strategy / 中华骨科杂志

Objective:To investigate the imaging features and surgical strategies of late-onset spinal deformity after myelomeningocele (MMC) repair.Methods:A total of 23 patients with late-onset spinal deformity after MMC repair from January 2006 to December 2019 were retrospectively analyzed, including 16 males and 7 females, aged 15.4±5.9 years (range, 6-28 years). All patients underwent MMC resection and repair in infancy (0-4 years). The complications of MMC, imaging characteristics of spinal deformity (Cobb angle of scoliosis, coronal balance, regional kyphosis), surgical methods, clinical outcomes and incidence of complications were analyzed. The Scoliosis Research Society-22 (SRS-22) score and Oswestry disability index (ODI) were used to evaluate the quality of life.Results:All patients were followed up for 2.4±0.8 years (range, 1-4 years). Among 23 patients, MMC occurred in the upper thoracic segment in 3 cases, thoracic segment in 1 case, thoracolumbar segment in 13 cases, and lumbosacral segment in 6 cases. 16 patients had scoliosis or kyphosis with the apex of the spine in the same segment as the MMC lesion. Among 13 patients with MMC located in thoracolumbar segment, 12 patients had scoliosis and 9 patients had kyphosis. Among 6 patients with MMC located in lumbosacral segment, 3 patients had pelvic tilt. Vertebral deformities included widening of pedicle space in 21 cases, enlargement of spinal canal in 19 cases, absence of spinous process in 17 cases, malsegmentation in 17 cases, and hemivertebra deformity in 9 cases. Intramedullary lesions included split cord in 6 cases and tethered cord in 9 cases. The overall implant density was 57.2%±17% (range, 16.6%-100%). At the last follow-up, the Cobb angle of scoliosis was 40.9°±19.1°, which was significantly smaller than 71.5°±28.2° before operation ( P<0.001). The local kyphosis angle was 26.7°±12.9°, which was significantly lower than that before operation (40.4°±21.5°), the difference was statistically significant ( P<0.001).The coronal balance was 16.1±13.6 mm, which was smaller than that before operation 28.5± 23.7 mm, the difference was statistically significant ( P<0.001). The total score of SRS-22 was 18.7±0.7, which was higher than that before operation 17.7±0.9, and the difference was statistically significant ( t=-9.74, P<0.001); ODI was 25.5%±6.2% after operation, which was significantly lower than that before operation (44.8%±10.1%), the difference was statistically significant ( t=13.66, P<0.001). Dural rupture occurred in 4 patients, including postoperative cerebrospinal fluid leakage in 2 cases; postoperative pleural effusion in 1 patient; and screw malposition in 2 patients. Three patients had broken rods and one had deep infection at final follow-up. Conclusion:About 70% of MMC patients who underwent resection and repair in early childhood developed late-onset spinal deformity in adulthood with the lesion at the parietal vertebrae. Posterior correction can obtain satisfactory clinical results. If the posterior element of the apical vertebral body is hypoplastic, the implant density can be increased by anterior vertebral screw, lamina hook fixation, and S 2 sacroiliac screw.

Severe kyphoscoliosis patients with type III spinal cord on preoperative apex MRI: preoperative traction does improve the safety of correction surgery / 中华骨科杂志

Objective:To analyze the radiographic improvements after Halo-gravity traction in severe kyphoscoliosis patientswith type III spinal cord on preoperative apex MRI, and to assess the clinical outcomes and surgical safety of Halo-gravity traction in this cohort.Methods:A total of 47 severe thoracic kyphoscoliosis patients with type III spinal cord on preoperative apex MRI who underwent preoperative Halo-gravity traction followed by one-stage posterior spinal fusion from February 2019 to June 2021 in the Nanjing Drum Tower Hospital were retrospectively analyzed. There were 18 males and 29 females with an average age of 22.5±12.8 years (range, 9-60 years). The average duration of traction was 7.4±3.9 weeks (range, 4-16 weeks). Radiographic parameters were measured including the coronal Cobb angle, distance between C 7 plumb line and center sacral vertical line (C 7PL-CSVL), sagittalglobal kyphosis (GK) and sagittal vertical axis (SVA) atpre-traction, post-traction and post-operation, respectively. The traction correction rate was measured as "traction degree before traction-traction degree after traction)/traction degree before traction" and the surgical correction rate was represented as "traction degree before traction-postoperative degree)/ traction degree before traction". The Frankel scoring system was used for the evaluation of neurological status at pre-traction, post-traction and post-operation. Results:All of 47 patients underwent the Halo-gravity traction and posterior spinal correction surgery. The C 7PL-CSVL was 35.7±16.9 mm at initial visit. At post-operation, C 7PL-CSVL was improved to 22.0±13.7 mm ( t=13.75, P<0.001), and the improvement rate was 39.9%±15.5%. The GK was 110.9°±22.1° at initial visit, which was improved to 84.1°±19.9° ( t=8.84, P<0.001) after Halo-gravity traction with an average correction of 23.7%±8.9%. At post-operation, GK was improved to 65.3°±19.3° ( t=10.63, P<0.001), and the improvement rate were 40.1%±20.7%. The SVA was 43.8±19.5 mm at initial visit. At post-operation, SVA was improved to 21.1±14.9 mm ( t=10.32, P<0.001), and the improvement rate were 53.1%±27.0%. A total of 14 patients showed neurological deficits of lower limbs at pre-traction, of which 8 patients had significant neurological improvement after Halo gravity traction; 3 patients had significant neurological improvement after surgery, and the remaining 3 patients had no significant neurological improvement during treatment. No new neurological deficits were observed after Halo-gravity traction or surgery. Conclusion:For severe kyphoscoliosis patients with type III spinal cord on preoperative apex MRI, the Halo-gravity traction could effectively correct the deformity, improve neurological function, enhance the tolerance of spinal cord to surgery and reduce the risk of intraoperative iatrogenic neurological deficit.

OBJECTIVE@#To develop and validate a three-year risk prediction model for new-onset cardiovascular diseases (CVD) among female patients with breast cancer.@*METHODS@#Based on the data from Inner Mongolia Regional Healthcare Information Platform, female breast cancer patients over 18 years old who had received anti-tumor treatments were included. The candidate predictors were selected by Lasso regression after being included according to the results of the multivariate Fine & Gray model. Cox proportional hazard model, Logistic regression model, Fine & Gray model, random forest model, and XGBoost model were trained on the training set, and the model performance was evaluated on the testing set. The discrimination was evaluated by the area under the curve (AUC) of the receiver operator characteristic curve (ROC), and the calibration was evaluated by the calibration curve.@*RESULTS@#A total of 19 325 breast cancer patients were identified, with an average age of (52.76±10.44) years. The median follow-up was 1.18 [interquartile range (IQR): 2.71] years. In the study, 7 856 patients (40.65%) developed CVD within 3 years after the diagnosis of breast cancer. The final selected variables included age at diagnosis of breast cancer, gross domestic product (GDP) of residence, tumor stage, history of hypertension, ischemic heart disease, and cerebrovascular disease, type of surgery, type of chemotherapy and radiotherapy. In terms of model discrimination, when not considering survival time, the AUC of the XGBoost model was significantly higher than that of the random forest model [0.660 (95%CI: 0.644-0.675) vs. 0.608 (95%CI: 0.591-0.624), P < 0.001] and Logistic regression model [0.609 (95%CI: 0.593-0.625), P < 0.001]. The Logistic regression model and the XGBoost model showed better calibration. When considering survival time, Cox proportional hazard model and Fine & Gray model showed no significant difference for AUC [0.600 (95%CI: 0.584-0.616) vs. 0.615 (95%CI: 0.599-0.631), P=0.188], but Fine & Gray model showed better calibration.@*CONCLUSION@#It is feasible to develop a risk prediction model for new-onset CVD of breast cancer based on regional medical data in China. When not considering survival time, the XGBoost model and the Logistic regression model both showed better performance; Fine & Gray model showed better performance in consideration of survival time.

Improvement of high-quality evaluation criteria of Chinese patent medicines based on whole process control / 中国中药杂志

Chinese patent medicines(CPMs) are unique therapeutic drugs in China. Establishing and improving the evaluation criteria is an important measure to promote the high-quality development of CPMs. Based on the "evaluation criteria of high-grade CPMs with quality as the core index" established by our group in 2018, the "high-quality evaluation criteria for CPMs based on whole process control" was proposed in the present study in 2022. The scope of application and basic principles of the new criteria were clarified. A quality evaluation scoring table was established in the new criteria, including five parts: raw material selection, production process, quality control, efficacy evaluation, and brand building. The technical evaluation indexes involved have increased from 20% in the original criteria to 70% in the new criteria, and efficacy evaluation has been added in the new criteria. The subjective evaluation indicators account for a large proportion in the original criteria, which is prone to bias. The improved criteria overcome this shortcoming. It is expected that the new criteria as a basis can play a better role in the selection of high-quality products of CPMs, guide enterprises and institutions to participate actively in the evaluation and research of high-quality CPMs, and promote the high-quality development of CPMs.

Intervention effect of Tuina pressing and kneading the Huantiao (GB30) acupoint on NF-κB p65 protein at spinal cord dorsal horn in sciatica rats / 中国骨伤

OBJECTIVE@#To observe the analgesic effect of Tuina by pressing and kneading the Huantiao (GB30) acupoint on rats with chronic constriction injury (CCI) and to explore the analgesic mechanism of Tuina on sciatica rats.@*METHODS@#Thirty-two SPF male SD rats weighing 180 to 220 g were randomly divided into fore groups:blank group (without any treatment), sham group (only exposed without sciatic nerve ligating), model group (sciatic nerve ligating) and Tuina group (manual intervention after lsciatic nerve ligating). The CCI model was prepared by ligating the right sciatic nerve of the rats, on the third day of modeling, the rats in the Tuina group were given pressing and kneading the Huantiao (GB30) point for 14 days, and the changes of paw withdrawal threshold(PWT), paw withdrawal latency(PWL) were measured before and on the 1st, 3rd, 7th, 10th, 14th and 17th days after modeling. The changes of sciatic functional index(SFI) were measured before and on the 1st and 17th day after modeling. The morphological changes of the sciatic nerve were observed by hematoxylin-eosin(HE) staining;and the differences in NF-κB protein expression in the right dorsal horn of the spinal cord of rats were detected.@*RESULTS@#Following modeling, there was no significant difference in PWT, PWL and SFI between the blank group and the sham group (P>0.05), but the PWT, PWL and SFI of the model group and the Tuina group decreased significantly (P<0.01). After manual intervention, the pain threshold of rats in Tuina group increased. On the 8th day of manual intervention (the 10th day after modeling), PWT in Tuina group increased significantly compared with that in model group (P<0.01). On the 5th day of manual intervention (the 7th day after modeling), the PWL of the massage group was significantly higher than that of the model group (P<0.01). The pain threshold of rats in Tuina group continued to rise with the continuous manipulation intervention. After 14 days of manipulative intervention, the sciatic nerve function index of rats in the Tuina group increased significantly(P<0.01). Compared with the blank group and sham group, the myelinated nerve fibers of sciatic nerve in the model group were disordered and the density of axons and myelin sheath was uneven. Compared with the model group, the nerve fibers of rats in the Tuina group were gradually continuous and the axons and myelin sheath were more uniform than those in the model group. Compared with the blank group and sham group, the expression of NF-κB protein in the right spinal dorsal horn of the model group was significantly increased(P<0.01). Compared with the model group, the expression of NF-κB protein in the right spinal dorsal horn of rats in Tuina group decreased significantly(P<0.01).@*CONCLUSION@#Pressing and kneading the Huantiao (GB30) point restores nerve fiber alignment;and improves the PWT、PWL and SFI in the CCI model by decreasing NF-κB p65 protein expression in the spinal dorsal horn. There fore, Tuina demmstrates an analgesic effect and improves the gait of rats with sciatica.

Network Meta-analysis of Chinese patent medicines in treatment of idiopathic membranous nephropathy / 中国中药杂志

This study aimed to systematically evaluate the efficacy and safety of different Chinese patent medicines in the treatment of idiopathic membranous nephropathy. The relevant randomized controlled trial(RCT) was retrieved from PubMed, EMbase, Cochrane Library, CNKI, SinoMed, Wanfang, and VIP with the time interval from database inception to December 2022. The Cochrane risk of bias assessment tool was employed to evaluate the quality of the included RCT, and Stata 15.0 and GEMTC to perform the Bayesian network Meta-analysis. Finally, 51 RCTs were included, involving 9 Chinese patent medicines and 3 591 patients. The results of network Meta-analysis showed that in terms of the total effective rate and the increase in plasma albumin, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Bailing Capsules + conventional western medicine, and Tripterygium Glycosides Tablets + conventional western medicine. In terms of reducing 24-hour urine total protein, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Shenfukang Capsules +conventional western medicine, and Huangkui Capsules + conventional western medicine. In terms of reducing serum creatinine, the top three interventions were Shenfukang Capsules + conventional western medicine, Bailing Capsules + conventional western medicine, and Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine. In terms of safety, Chinese patent medicines combined with conventional western medicine had fewer adverse reactions than the control group. The results suggest that Chinese patent medicines combined with conventional western medicine can improve the therapeutic effect on idiopathic membranous nephropathy, and differentiated medications can be adopted according to the specific symptoms of patients in clinical treatment. Further validation needs to be carried out in the future with multi-center, large-sample, and high-quality RCT.

Early experience of femoropopliteal calcified lesion debulking with Rotarex ? S / 中国医师杂志

Objective:To investigate the clinical value of Rotarex ? S in debulking the femoropopliteal calcified lesion. Methods:The data of 5 patients with femoropopliteal calcified lesions treated with Rotarex ? S combined with drug balloon treatment admitted to the First Affiliated Hospital of Dalian Medical University from March 2020 to December 2021 were retrospectively analyzed.
