Objective@#To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD.@*Methods@#Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model.@*Results@#A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966).@*Conclusion@#The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Objective:This study compared the prevalence,awareness,treatment and control of hypertension and associated factors in China and the United States(US).Methods:Adult data from nationally representative samples were derived from the Chronic Disease and Risk Factors Surveillance in 2010 and 2013 in China and the National Health and Nutrition Examination Survey in 2010 and 2013 in the US.Multivariable logistic and Poisson regression analysis were conducted to assess associations of the four outcomes with body weight status and behavioral factors.Results:Age-standardized prevalence rates of hypertension was 35.7%(95%confidence interval[CI]:35.4%to 36.1%)in 2010 and 29.8%(95%CI:29.4%to 30.2%)in 2013 in China,and 35.3%(95%CI:33.6%to 37.1%)in 2010 and 37.9%(95%CI:36.0%to 39.7%)in 2013 in the US.Among hypertensive participants,the age-standardized rates of treatment were 18.4%(95%CI:17.9%to 18.9%)in 2010 and 23.8%(95%CI:23.1%to 24.6%)in 2013 in China and 54.5%(95%CI:50.3%to 58.7%)in 2010 and 50.9%(95%CI:46.5%to 55.3%)in 2013 in the US;the age-standardized hypertension control rates were 3.2%(95%CI:3.0%to 3.5%)and 5.7%(95%CI:5.3%to 6.0%)in 2010 and 2013 in China and 50.6%(95%CI:46.2%to 55.0%)and 55.3%(95%CI:50.3%to 60.3%)in the US.Obesity was significantly associated with prevalence,awareness and control rates in both countries.Different from the US,obesity was negatively associated with hypertension control in China.Conclusion:Hypertension prevalence in China is similar to that in the US,but the control rate in China was significantly lower.Obesity was a critical risk factor for poor hypertension control in China.
摘要
Carcinoma of unknown primary (CUP) is a kind of metastatic tumor whose primary origin cannot be identified after adequate examination and evaluation. The main treatment modality of CUP is empiric chemotherapy, and the median overall survival time is less than 1 year. Compared with immunohistochemistry, novel method based on gene expression profiling have improved the sensitivity and specificity of CUP detection, but its guiding value for treatment is still controversial. The approval of immune checkpoint inhibitors and pan-cancer antitumor agents has improved the prognosis of patients with CUP, and targeted therapy and immunotherapy based on specific molecular characteristics are the main directions of future research. Given the high heterogeneity and unique clinicopathological characteristics of CUP, "basket trial" is more suitable for clinical trial design in CUP.

OBJECTIVE@#To study the association of body fat ratio with precocious puberty in girls. Previous studies have shown that body mass index (BMI) is associated with the girls' age of puberty but have not revealed the association of body fat ratio with age of puberty.@*METHODS@#Based on the consensus on the diagnosis and treatment of central precocious puberty (CPP), 128 children with precocious puberty who were admitted to the hospital from July to August, 2017, were divided into a CPP group with 87 children and a peripheral precocious puberty (PPP) group with 41 children. A total of 51 girls without any puberty development signs were enrolled as the control group. Dual-energy X-ray absorptiometry was used to measure the body fat ratios of upper limbs, legs, trunk, android area, gynoid area, and the whole body. The association between body fat ratios and precocious puberty was analyzed with reference to age, BMI, BMI-Z score, bone age, ovarian volume, and hormone levels.@*RESULTS@#Compared with the control group, the CPP and PPP groups had significantly higher body fat ratios of upper limbs, legs, trunk, android area, gynoid area, and the whole body, legs/whole body fat ratio, and (upper limbs+legs)/trunk fat ratio (P0.05). For the girls with precocious puberty, the high body fat ratio group had significantly higher luteinizing hormone (LH) base value, luteinizing hormone releasing hormone (LHRH)-stimulated LH peak value, and LH/follicle-stimulating hormone peak value than the low body fat ratio group (P<0.05). Compared with the control group, both the high body fat ratio and low body fat ratio groups had a significantly higher LH base value (P<0.05).@*CONCLUSIONS@#The increase in body fat may be a factor inducing precocious puberty in girls, but further studies are needed to determine the mechanism.

Objective:To observe the effect of warm joint needling plus rehabilitation techniques on the balance function and quality of life (QOL) of patients with spastic hemiplegia after ischemic cerebral stroke.Methods:Ninety patients with spastic hemiplegia after ischemic cerebral stroke were randomized into a rehabilitation group,a warm joint needling group and an observation group,with 30 cases in each group.The rehabilitation group was intervened by Bobath therapy,the warm joint needling group was treated with joint needling on the affected side plus warm needling,and the observation group was given the same rehabilitation treatment as the rehabilitation group together with the same warm joint needling as the warm joint needling group.The three groups were treated once another day,1 month as a treatment course for 6 months.Before the treatment,and respectively after 2-week,1-month,3-month,and 6-month treatment,the modified Ashworth scale (MAS) was used to measure the anti-spasm ability of the lower limb,the Berg balance scale (BBS) was adopted to evaluate the balance function,and the stroke-specific quality of life scale (SS-QOL)was employed to estimate the QOL.Results:After 3-month and 6-month treatment,the lower-limb MAS scores in the observation group were significantly better than those in the rehabilitation group and the warm joint needling group (all P<0.05).After 1-month,3-month and 6-month treatment,the BBS scores in the observation group were significantly better than those in the rehabilitation group and the warm joint needling group (all P<0.05).After 2-week,1-month,3-month and 6-month treatment,the SS-QOL scores in the observation group were markedly better than those in the rehabilitation group and the warm joint needling group (all P<0.05).Conclusion:Warm joint needling plus rehabilitation can effectively improve the lower-limb spasticity state,balance function and QOL in patients with spastic hemiplegia after ischemic cerebral stroke.
摘要
Objective@#The purpose of this study was to explore the surgery-first approach in sequential combined orthodontic-orthognathic treatment to shorten total treatment duration and improve the clinical outcome.@*Methods@#This study included 185 patients with Angle classⅢ malocclusion. The patients were divided into 3 different types according to cephalometry analyses and facial features. ①Type Ⅰ: mandibular prognathism or asymmetry mandibular prognathism; ②Type Ⅱ: mandibular prognathism and maxillary retrusion; ③ Type Ⅲ: mild Angle′s Class Ⅲ malocclusion, cross bite in anterior teeth, or normal overlap and overbite relation with midfacial hypoplasia. All of patients received surgery first approach therapy. The surgical procedures were chosen according to different malformation types. Type Ⅰ was treated with the sagittal split ramus osteotomy (SSRO). Type Ⅱ was treated by Le Fort Ⅰmaxillary osteotomy combined with SSRO. Type Ⅲ underwent anterior subapical osteotomy combined pyriform aperture augmentation with biomaterials as well as maxillary anterior orthodontics. All patients received postoperative rapid orthodontic treatment for 6-12 month after 2 weeks of operation. Using the straight arch wire techniques and the class Ⅲ intermaxillary traction, we removed the overcrowding upper and lower teeth, the compensatory axial tilt of teeth, and the deviation of the dental arch and maintained the neutral relationship of the molar. The mandible Hawley retaining devices were used during the maintaining stage.@*Results@#The cases in study acquired satisfactory clinical outcome, which included the shortened overall treatment duration, the significantly improved facial features, the corrected occlusion relationship, and the restored function of mastication and temporomandibular joint. There were some complications as follows: intraoperative fracture (6 cases, 3.24%), the inferior alveolar nerve bundle injury (2 cases, 1.1%), and temporary open-bite that diminished by inter-maxillary elastic distraction one month after operation (19 cases, 10%). All cases in this study accepted postoperative orthodontic treatment. Follow-up time ranged from 6 months to 5 years. The cephalometric analysis results of 126 cases who had complete image data and over 6 months of follow-up showed that hard and soft tissue indexes were restored to normal range after combined orthognathic-orthodontic treatment. The stability of the maxillary and occlusive relationship of SFA(surgery-first approach) was similar to that of the COS(conventional orthodontics-first system) [relapse ratio=(T2-T1)/(T1-T0)×100%]. Over six months of follow-up , SNB and ANB showed that the average relapse ratio were 22% and 19.8%, whereas the relapse angle are less than 2°.@*Conclusions@#The Surgery-first approach could be used to treat most patients with Angle skeletal Class Ⅲ malocclusion, but the indications and the surgical procedures should be noticed and chosen.

摘要
The well-known detrimental effects of cadmium (Cd) on plants are chloroplast destruction, photosynthetic pigment inhibition, imbalance of essential plant nutrients, and membrane damage. Jasmonic acid (JA) is an alleviator against different stresses such as salinity and drought. However, the functional attributes of JA in plants such as the interactive effects of JA application and Cd on rapeseed in response to heavy metal stress remain unclear. JA at 50 µmol/L was observed in literature to have senescence effects in plants. In the present study, 25 µmol/L JA is observed to be a "stress ameliorating molecule" by improving the tolerance of rapeseed plants to Cd toxicity. JA reduces the Cd uptake in the leaves, thereby reducing membrane damage and malondialdehyde content and increasing the essential nutrient uptake. Furthermore, JA shields the chloroplast against the damaging effects of Cd, thereby increasing gas exchange and photosynthetic pigments. Moreover, JA modulates the antioxidant enzyme activity to strengthen the internal defense system. Our results demonstrate the function of JA in alleviating Cd toxicity and its underlying mechanism. Moreover, JA attenuates the damage of Cd to plants. This study enriches our knowledge regarding the use of and protection provided by JA in Cd stress.

Objective To explore the diagnostic value of non-real-time radial probe endobronchial ultrasound (RP-EBUS) guided transbronchial lung biopsy (TBLB) for peripheral lung cancer and analysis of false negative results. Methods A retrospective analysis of the clinical and imaging data of 256 patients with peripheral lung cancer between March 2013 and December 2016, all the cases underwent non-real-time RP-EBUS guided TBLB, then evaluate its significance in the diagnosis of peripheral lung cancer and analyze the reasons of false negative results. Result In 256 patients who received non-real-time RP-EBUS examinations, 73.83% (189/256) of peripheral lung cancer were detected by RP-EBUS and the positive rate of RP-EBUS guided TBLB was 61.33% (157/256). The positive rate of non-real-time RP-EBUS guided TBLB was correlated with lesions >2 cm in diameter, lesions close to visceral pleura, ultrasonic image characteristics and the RP-EBUS probe surrounding by lesion (P < 0.05). The positive rate of non-real-time RP-EBUS guided TBLB was not correlated with RP-EBUS probe passed through lesions and times of biopsy (P > 0.05). Complications including bleeding, chest pain and pneumothorax recovered spontaneously. Conclusion Non-real-time RP-EBUS guided TBLB was a practical technology for diagnosis of peripheral lung cancer with high diagnostic rate and good safety. Lesion size, connection to visceral pleura, ultrasonic image characteristics and the RP-EBUS probe surrounding by lesion influenced the diagnostic yield. Improvement of operative skills can reduce false negative results.

Objective@#To study the feasibility of 18F-fluoro-L-dihydroxyphenylalanine positron emission tomography/Computed tomography (18F-DOPA PET/CT) scanning in the localization and differential diagnosing of focal versus diffuse form of pancreas lesions in patients with hyperinsulinemic hypoglycemia (HH).@*Method@#Twenty-four patients were diagnosed with HH between January, 2016 and February, 2017 in the Department of Pediatric Endocrinology and Inherited Metabolic Diseases, Children′s Hospital of Fudan University using an integrated clinical and biochemical diagnostic protocol, domestic 18F-DOPA PET/CT imaging technique were applied after MRI and ultrasound failed to detect pancreas lesions. Pancreas 18F-DOPA standardized uptake values (SUV) were measured, and pancreas′ lesions were dually analyzed via visual method and pancreas percentage SUV method. Among these patients, 9 patients received surgical pancreatic lesion resections, the correlations among surgical outcomes, histopathological findings and 18F-DOPA PET/CT scan results were analyzed.@*Result@#Seven patients were detected with focal form of pancreas lesions, the mean peak of SUV was 4.7±1.7(2.6-7.1), and 17 patients were found to have diffuse form lesions after 18F-DOPA-PET/CT scanning. Among the 24 cases, 9 patients (7 showed focal and 2 showed diffuse 18F-DOPA PET/CT pancreatic uptake)were euglycemic without any medical support after surgery; the resected pancreatic tissue histopathological results were consistent with that of PET/CT imaging. Only one patient, who responded to medical treatment before surgery, had temporary hyperglycemia after operation.@*Conclusion@#Domestic 18F-DOPA PET/CT could successfully locate and differentiate the pancreatic lesions and thus improve the success of surgery.
摘要
Microglial activation and resultant neuroinflammatory response are implicated in various brain diseases including Alzheimer's disease and Parkinson's disease. Treatment with anti-neuroinflammatory agents could provide therapeutic benefits for such disorders. Protosappanin A (PTA) is a major bioactive ingredient isolated from Caesalpinia sappan L.. In this work, the anti-neuroinflammatory effects of PTA on LPS-stimulated BV2 cells were investigated and the underlying mechanisms were explored. Results showed that PTA significantly inhibited the production of TNF-α and IL-1β in LPS-activated BV2 microglia. Moreover, the mRNA expressions of IL-6, IL-1β, and MCP-1 were reduced by PTA in a dose-dependent manner. Furthermore, PTA suppressed JAK2/STAT3-dependent inflammation pathway through down-regulating the phosphorylation of JAK2 and STAT3, as well as STAT3 nuclear translocation against LPS treatment. These observations suggested a novel role for PTA in regulating LPS-induced neuroinflammatory injuries.
