Objective To investigate the correlation of uric acid(UA) level and the circadian rhythm of blood pressure in hypertensive patients. Methods Among the individuals who presented to the cardiology clinic, 70 patients who had hypertension and were diagnozed with non- dipper hypertension (non-dipper hypertension group) by 24 h ambulatory blood pressure monitoring (ABPM), 70 patients with dipper hypertension patients (dipper hypertension group), and 52 normotensive individuals (control group) were enrolled in this study. Peripheral venous blood samples were collected from all the patients in order to evaluate the hematological and biochemical parameters. All the assessed parameters were compared among three groups. Results The level of UA in non-dipper hypertension group was the highest, in dipper hypertension group was higher and in contrl group was the lowerst:(393.57 ± 53.52), (280.57 ± 41.64), (267.66 ± 59.38) μmol/L, and there were significant differences (P<0.01). Multivariate Logistic regression analysis revealed that the level of UA was an independent risk factor for non-dipper circadian rhythm of blood pressure (P = 0.003, OR = 2.26, 95% CI: 1.34- 3.89). Conclusions The higher level of UA may be a risk factor for non-dipper circadian rhythm of blood pressure in hypertension patients.

In 1999, the nomenclature and case definitions for neuropsychiatric lupus syndromes were published by American College of Rheumatology (ACR), and the cognition of neuropsychiatric damage of systemic lupus erythematosus (SLE) was gradually unified and standardized. Lupus headache is an intractable problem in SLE, especially in SLE patients complicated with multiple organ injury. In general, vascular headache is common in most SLE patients, and a small number of SLE patients complicated with nervous headache are found in clinic. Moreover, its pathophysiological mechanism is far from being understood. Although early diagnosis is essential for good outcomes, the diagnosis method is rather confused in the world. There still exist some limitations in the proposal of clinical classification of headache from ACR and International Headache Society (IHS), and the proposal does not mention the classification of headache related to psychiatric damage. Current therapeutic regimens are almost exclusively based on empirical evidence. Treatment approaches include symptomatic treatment, immunosuppressive, anticoagulant and anti-aggregant therapies. It provides enormous and hopeful space in research of combined therapy strategy, especially in the field of traditional Chinese medicine. The authors discussed the relationship between lupus headache and headache due to internal injury in the view of integrated traditional Chinese and Western medicine, and suggested that the treatment strategy for lupus headache should be made in argument with the headache due to internal injury. Syndrome differentiation treatment according to deficiency in the root and excess in the branch and the therapy for activating blood to dredge collaterals maybe have great advantages in treatment of the headache in SLE.

Objective:To analyze the public demands for information about congenital birth defects in “Baidu zhidao” based on word frequency retrieval.Methods:Based on discussion between obstetrics and gynecology experts and epidemiological experts, the key words related to congenital birth defects were determined and the search strategy was formulated. Python 2.7 was used for web crawler search. Questions related to congenital birth defects were obtained on the “Baidu zhidao” platform, and then the R 4.0.2 software was used to process the data, complete the semantic analysis of keywords and statistical analysis of word frequency, and draw word cloud graph and polar chart to describe the key results.Results:A total of 16668 non-repetitive questions were retrieved from “Baidu zhidao” platform, and the frequency of semantic words was 15 371. Among them, 35.02% were the names and symptoms of congenital birth defects. In addition, the frequency of congenital heart disease was the highest (26.09%). The results of subject analysis of key words of birth defects showed that the average word frequency of diagnosis and treatment semantic words (49.55) was significantly higher than that of etiology and prevention semantic words (12.47). In addition, the key words of examination, cause, treatment, development and heredity were more frequently used in the semantic words related to the seven types of systemic malformations.Conclusion:The public in China has a high demand for information on congenital birth defect related diseases, and their causes, prevention and treatment, especially congenital heart disease.

BACKGROUND:Pulsed electromagnetic field is a non-invasive and non-radiative treatment method.Clinical use of pulsed electromagnetic fields in the treatment of orthopedic diseases has achieved certain results. OBJECTIVE:To review the current clinical application of the pulsed electromagnetic field in the treatment of orthopedic diseases,providing a scientific theoretical basis for the clinical treatment of orthopedic diseases. METHODS:The first author used a computer to search PubMed,CBM,Cochrane Library,CNKI,and WanFang Data for related studies on the pulsed electromagnetic field in the treatment of orthopedic diseases,using the keywords of"pulsed electromagnetic field,orthopedics,osteoarthritis,osteoporosis,bone healing,electromagnetic navigation"in English and Chinese.For the literature related to the same content,recent publications were selected.A total of 69 articles were selected from the search results for review. RESULTS AND CONCLUSION:Pulsed electromagnetic field has a definite curative effect on fracture healing.It can be used in the treatment of osteomyelitis by antibacterial,bactericidal,anti-inflammatory and promoting bone healing,and can inhibit osteoporosis and its progress.In addition,the treatment of early osteoarthritis,femoral head necrosis and postoperative rehabilitation of late joint replacement through various ways can become a treatment for orthopedic diseases.However,the therapeutic mechanism of the pulsed electromagnetic field for a variety of orthopedic diseases is still unclear,and most of the research is still in the primary stage.In the future,it is still necessary to obtain more reliable evidence from high-quality research and clinical trials to provide a more perfect basis for the clinical treatment of orthopedic diseases.

Objective:To select human chronic myeloid leukemia (CML) cell line K562 as the experimental object, and use lentivirus mediated CRISPR/Cas9 gene editing technology to construct a stable CML cell line K562/TCRP1-KO that knocks out the tongue cancer resistance related protein 1 (TCRP1) gene; and through functional tests such as cell proliferation, apoptosis, and drug sensitivity, compare the phenotypic differences between K562/TCRP1-KO and control cells (K562/cas9-CTL), and preliminarily explore the possible mechanism of TCRP1 gene involvement in the pathogenesis of CML.Methods:The small guide RNA (sgRNA) targeting TCRP1 was designed at a specific location. After annealing, the oligonucleotide fragments were recombined with the linearized Cas9 expression vector, and the lentivirus packaging system was transfected into 293T cells. The purified virus was collected and infected with K562 cells. Positive polyclons were screened for puromycin pressure, and monoclonal K562/TCRP1-KO was further screened by limited dilution method. Stable cell lines were successfully knocked out by sanger sequencing and Western blot detection; Simultaneously, K562 cells transfected with lentiCRISPR vector were constructed as control cell lines (K562/cas9-CTL); Using cell counting method, cell counting kit 8 (CCK8) method, imatinib (IM) gradient dilution method, and flow cytometry cell proliferation, drug sensitivity, and apoptosis analysis were performed on K562/TCRP1-KO and K562/cas9-CTL, respectively.Results:The sgRNA-Cas9 recombinant plasmid vector for TCRP1 knockout was successfully constructed, and after transfection into 293T cells, TCRP1 knockout monoclonal cell lines were successfully screened using limited dilution method. Compared with K562/cas9-CTL cells, the proliferation ability of K562/TCRP1-KO cells was significantly reduced, IM drug sensitivity was significantly enhanced, and the process of cell apoptosis was significantly accelerated (all P<0.05). Conclusions:A CML cell line with TCRP1 knockout was successfully constructed using CRISPR/Cas9. TCRP1 may act as a cancer related gene to affect the proliferation, IM resistance, and apoptosis process of CML cells.

OBJECTIVETo determine the percentage of hypercholesterolemic patients who had met the criteria as total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C), defined by the Chinese National Recommendations for Prevention and Treatment of Dyslipidemia.
METHODSAdult patients with hypercholesterolemia, who had been receiving the same lipid-lowering therapy for at least 2 months, were enrolled. Lipid levels were determined at the time of enrollment, to assess whether the patients' lipid levels had reached the criteria for treatment. Patients' cardiovascular risk factors and lipid-lowering treatments were also collected.
RESULTSOne hundred and eighty patients with mean age of 65.8 were studied. Of these, 6.7% had no risk factors and no definite disease of atherosclerosis (low-risk group), 65.5% had risk factors but no documented atherosclerosis (high-risk group), and 27.8% had established atherosclerosis diseases or diabetes mellitus. Overall, only 44% of patients achieved both TC and LDL-C target levels. The success rates were higher among low and high-risk groups than that among patients with atherosclerosis or diabetes mellitus. The relationship between four different lipid-lowering drug therapies and successful patient outcome was also investigated. The success rates were 51.8% for simvastatin, 42.9% for pravastatin, 31.6% for fluvastatin, 12.5% for other drugs respectively.
CONCLUSIONMore than half of the hypercholesterolemic patients receiving lipid-lowering therapy had not achieved TC and LDL-C target levels. Data from this study indicated that a significant gap still existed between dyslipidemia prevention principles and clinical practices, suggesting that more aggressive treatment of dyslipidemia is needed.

Objective:To compare the efficacy of 3D navigation versus C-arm fluoroscopy for placement of percutaneous double-segment long sacroiliac screws in the treatment of injury to the posterior pelvic ring.Methods:A retrospective study was conducted in the 48 patients with pelvic fracture who had been treated surgically from February 2015 to October 2020 at Department of Orthopaedics, General Hospital of Central Command of PLA. The patients were divided into a navigation group and a fluoroscopy group according to their different auxiliary ways to assist screw placement. In the navigation group of 27 patients, there were 19 males and 8 females, with an age of (45.5±7.4) years; in the fluoroscopy group of 21 patients, there were 14 males and 7 females, with an age of (44.1±10.1) years. The 2 groups were compared in terms of placement time for each screw, fluoroscopy time for each screw, adjustments of guide wire, accuracy of screw position, quality of fracture reduction, fracture union time, pelvic function, and postoperative complications.Results:The 2 groups were comparable because there was no significant difference between them in the preoperative general data ( P>0.05). The placement time for each screw [(12.7±2.2) min], fluoroscopy time for each screw [(40.7±9.3) s] and adjustments of guide wire [1 (0,1) time] in the navigation group were significantly less than those in the fluoroscopy group [(23.7±3.6) min, (71.4±14.1)s and 5 (4,6) times] (all P<0.05); the assessment of screw placement in the former (49 excellent, 4 good and one poor cases) was significantly better than that in the latter (29 excellent, 8 good and 5 poor cases) ( P<0.05). The 48 patients were followed up for 8 to 25 months (mean, 13.1 months). There were no significant differences between the 2 groups in fracture union time, quality of fracture reduction or Majeed scores for the pelvic function (all P>0.05).Symptoms of injury to the L5 nerve root were observed in one patient in the fluoroscopy group; none of the patients reported postoperative complications like wound infection, screw loosening or breaking. Conclusions:Compared with C-arm fluoroscopy, 3D navigation may better assist placement of percutaneous double-segment long sacroiliac screws in the treatment of injury to the posterior pelvic ring, because 3D navigation can significantly shorten the time for screw placement and the fluoroscopy time for screw placement, reduce adjustments of guide wire, and improve accuracy of screw placement.
