Objective To observe the effect of atorvastatin on intraabdominal fat and microalbuminuria (MAU) in patients with metabolic syndrome (MS). Methods Forty-four MS patients were divided into the atorvastatin group and the control group. Blood pressure and blood glucose were controlled in both groups, in addition, atorvastatin was administered to the patients in the atorvastatin group. Blood pressure, blood glucose, body weight, abdominal wall fat, intraabdominal fat and MAU were compared before and after 12 weeks’ treatment. Results Obvious decrease of the intraabdominal fat and MAU was found in the atorvastatin group compared with those before the treatment Intraabdominal fat: non-ACE1/ARB (41.76?3.61) mm vs (33.23?2.47) mm, P

Objective To investigate the effect of human papilloma virus (HPV) DNA detection on cervical cancer and its precancerous lesions screening.Methods A total of 2 852 patients participated in cervical screening in Sichuan Provincial People's Hospital from January 2014 to December 2016 were enrolled.The HPV DNA testing and pathological biopsy were conducted in all patients,and the pathological examination results were defined as the gold standard.The influences of age,regions of residence (rural and urban) and obesity on the positive rate of HPV DNA were analysed.The results of HPV DNA testing in different pathological types were compared,and the sensitivity,specificity,positive predictive value,negative predictive value of of HPV DNA testing were analysed,as well.Results The positive rate of HPV DNA in the 18-＜35 age group was significantly higher than that in the 35-＜50 age group and 50-58 age group,the differences were statistically significant (P＜0.05).There was no statistically significant difference in positive rate of HPV DNA between the 35-＜50 age group and 50-58 age group (P＞0.05).The positive rate of HPV DNA of patients in urban areas was significantly lower than that of those patients in rural areas (P＜0.05),while no statistically significant difference was found in the positive rate of HPV DNA between patients with normal weight and patients whose weight exceeded the standard (P＞0.05).Among patients with positive HPV DNA testing results,the detection rate of cervical cancer and its precancerous lesions based on pathological examination was 1.60 ％ and 28.60 ％,respectively.The sensitivity,specificity,positive predictive value,negative predictive value and missed diagnosis rate of HPV DNA testing was 87.79％,86.98 ％,30.20 ％,99.11％ and 12.21％,respectively.Conclusion HPV DNA detection has a high sensitivity and specificity in cervical screening.

Objective To explore the rapid diagnosis and clinic treatment of donor-derived carbapenem-resistant Klebsiella pneumoniae (CRKP) infection in renal transplant recipients .Methods Retrospective analysis was performed for clinical data and the diagnosis and treatment of 9 renal transplant recipients with donor-derived CRKP infection from March 2017 to May 2019 .Results Among 526 renal transplant recipients ,nine were diagnosed with donor-derived CRKP infection by bacterial culture or KPC enzyme gene test .The infection rate was 1 .71％ .One recipient receiving carbapenem and tigecycline died while the remainders survived after a treatment of ceftazidime-avibactam and carbapenem . One recipient underwent graft resection . Among 8 recipients on ceftazidime-avibactam ,5 cases received a standard dose of 3 .75 g/d while another 3 cases had a high dose of 7 .5 g/d .One patient in standard-dose group underwent graft resection due to an arteriorrhexis of artery anastomosis .After graft resection ,the patient received a high dose of ceftazidime-avibactam and survived to date .The grafts of three patients in high-dose treatment group survived .Conclusions KPC enzyme gene detection plus injecting lavage fluid into blood culture bottle for bacterial culture is rapid and accurate for diagnosing donor-derived CRKP infection . A combination of ceftazidime-avibactam plus carbapenem is effective for donor-derived CRKP infection .A high dose of ceftazidime-avibactam may improve the efficacy without obvious side effects .

BACKGROUND:Laser therapy is a non-invasive and painless treatment that is considered to be an effective method suitable for the treatment of osteoarthritis due to its simplicity and non-invasive nature.Currently,the mechanism of action of laser therapy is unclear and the results of studies on its clinical application are controversial. OBJECTIVE:To review and summarize the latest research progress of laser therapy on chondrocytes,animal experiments and clinical efficacy,and to explore the possible mechanism of laser-mediated multi-pathway biological effects,so as to provide a theoretical basis for further research on the laser treatment of osteoarthritis of the knee joint. METHODS:A literature search was performed in CNKI,WanFang Data,VIP and PubMed databases for relevant literature published from 2018 to 2023,with"laser therapy,low level laser therapy,high level laser therapy,photobiomodulation,knee osteoarthritis,chondrocytes"as the search terms in Chinese and English,respectively.Together with 14 articles searched manually,70 articles were finally included for review. RESULTS AND CONCLUSION:Laser therapy in the treatment of knee osteoarthritis is mainly categorized into two types:low-level laser therapy and high-level laser therapy.Differences in laser parameters and treatment protocols have a direct impact on laser efficacy.When appropriate parameters are used,low-level lasers show positive effects in cellular experiments,animal models,and clinical efficacy.High-level lasers have been less studied in the treatment of knee osteoarthritis,but some preliminary clinical studies have shown positive results.Cell experiments have shown that low-level laser promotes chondrocyte proliferation and cartilage matrix synthesis,thereby reducing inflammatory response.Animal experiments have shown that low-level laser can reduce the release of pro-inflammatory factors,promote cartilage matrix synthesis,inhibit matrix degradation,and effectively improve the repair process of cartilage tissue.Low-level laser is also able to reduce oxidative stress damage and relieve pain in knee osteoarthritis.In clinical trials,both low-and high-level laser can reduce patients'pain and improve functional activities.The combination of laser therapy and exercise therapy modalities may improve the therapeutic effect.Lasers may affect intracellular signaling and cellular functions through photobiological or thermodynamic effects.This provides direct evidence that laser promotes articular cartilage regeneration.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.

Ankylosing spondylitis (AS) combined with spinal fractures with thoracic and lumbar fracture as the most common type shows characteristics of unstable fracture, high incidence of nerve injury, high mortality and high disability rate. The diagnosis may be missed because it is mostly caused by low-energy injury, when spinal rigidity and osteoporosis have a great impact on the accuracy of imaging examination. At the same time, the treatment choices are controversial, with no relevant specifications. Non-operative treatments can easily lead to bone nonunion, pseudoarthrosis and delayed nerve injury, while surgeries may be failed due to internal fixation failure. At present, there are no evidence-based guidelines for the diagnosis and treatment of AS combined with thoracic and lumbar fracture. In this context, the Spinal Trauma Academic Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate the Clinical guideline for the diagnosis and treatment of adult ankylosing spondylitis combined with thoracolumbar fracture ( version 2023) by following the principles of evidence-based medicine and systematically review related literatures. Ten recommendations on the diagnosis, imaging evaluation, classification and treatment of AS combined with thoracic and lumbar fracture were put forward, aiming to standardize the clinical diagnosis and treatment of such disorder.

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.
