Objective To explore the mediating effect of triglyceride-glucose(TyG)index on the risk of proteinuria in patients with type 2 diabetes mellitus(T2DM).Methods 734 patients with T2DM who underwent routine physical examination in Quyang Road Community Health Service Center,Shanghai from March 2023 to May 2023 were enrolled.The results of basic information,biochemical indicators,abdominal ultrasound and other results were collected.All patients were divided into the normal group,microproteinuria group,and massiveproteinuria group,and stratification analyses were underwent according to glycated hemoglobin(HbA1c),body mass index(BMI),TyG index,and presence or absence of non-alcoholic fatty liver disease(NAFLD).Factors affecting proteinuria in T2DM patients were analyzed.Multivariate logistic regression was used to analyze the impact of TyG index and NAFLD on proteinuria in type 2 diabetes population.Regression coefficient sequential test was used to analyze whether TyG mediates NAFLD associated proteinuria.Results There were statistically significant differences in age,BMI,urinary creatinine,HbA1c,TyG index,etc.among the normal group,microproteinuria group,and massiveproteinuria group(all P＜0.05);there was no statistically significant difference in gender among the three groups.Multivariate logistic regression analysis showed that taking the HbA1c＜7％and BMI＜24 kg/m2 group as a reference,the patients with HbA1c≥7％and BMI≥24 kg/m2 had the highest risk of proteinuria(P=0.022),followed by the HbA1c≥7％and BMI＜24 kg/m2 group(P=0.039).Taking the TyG index(7.65-8.69)as a reference,the risk of proteinuria in the(9.45-11.90)group was 3.321 times(P＜0.001).The mediation effect analysis showed that the TyG mediated NAFLD associated proteinuria(P＜0.001),with the mediation effect accounting for 55.70％of the total effect.Conclusion TyG index may be an independent risk factor for proteinuria in patients with T2DM,and the prevalence of proteinuria is high in patients with poor control in HbA1c and excessive BMI,and TyG may partially mediate the risk of proteinuria in patients with T2DM.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Wake up ischemic stroke (WUIS),also known as awakening stroke,refers to patients with no new stroke symptoms during sleep,but after waking up,the patients or witness who found the acute cerebral infarction with stroke performance.The key to the treatment of acute ischernic stroke is to effectively restore reperfusion within the time window.The original intravenous recombinant tissue-type plasminogen activator (rt-PA) thrombolytic therapy,is widely recognized as an effective treatment method of choice for 4.5h onset of acute ischemic stroke reperfusion.Because the exact onset time of WUIS is unclear and limited by current scientific and technical levels,intravenous thrombolysis may lead to an increased risk of intracranial hemorrhage.Therefore,the American Heart Association and the American Stroke Association (AHA/ASA) were included in the "Intravenous Thrombolysis".Intravenous thrombolysis is not recommended in the Standard Scientific Statement.Patients who may be suitable for thrombolytic therapy are not able to obtain thrombolytic therapy,resulting in poor clinical prognosis.In recent years,with the further development of relevant clinical research and the rapid development of imaging technology,the latest research found that multi-mode imaging examination is safe and effective for intravenous thrombolytic therapy in patients with poststroke stroke.Multi-mode imaging studies help screening patients with acute reperfusion therapy,so that part of WUIS patients will benefit from the acute reperfusion therapy.This article reviews and summarizes the literature findings of WUIS in recent years.The pathophysiological changes,clinical features and imaging changes of patients with WUIS and non-WUIS are almost unanimously.Early CT and MRI examinations can help to extend acute stroke treatment to patients with WUIS.At present,for this type of patients,there are great research progress in the formulation and implementation of clinical treatment strategies.This article will briefly summarize the research progress and treatment status of WUIS.

Objective To evaluate the injury of retinal microstructure using optical coherence tomography (OCT) and investigate the role of aquaporin 4 antibody (AQP4 Ab) in this injury process.Methods Forty patients with neuromyelitis optica spectrum disorders (NMOSD) were retrospectively studied,each of whom reported at least one episode of optic neuritis (ON),namely 59 ON eyes involved in all.All patients were divided into two subgroups based on AQP4 Ab tests including 25 patients (37 ON eyes) with AQP4 positive (Ab+/NMOSD group) and 15 patients (22 ON eyes) negative (Ab-/NMOSD group).In addition,10 healthy controls (20 eyes) matched for age and sex (HC group) were analyzed.Spectral domain optical coherence tomography (SD-OCT) was used to quantify peripapillary retinal nerve fiber layer (RNFL).Nonparametric test was used to compare differences between groups.Results Age distribution and gender ratio were comparable in three groups (P＞0.05).Visual acuity in ON eyes of Ab+/NMOSD group was worse than that of Ab-/NMOSD group (P=0.02).There were no significant differences between Ab+/NMOSD and Ab-/NMOSD in aspects of disease duration (2.6 vs.1.9 year),ON episodes (2 vs.1),longitudinal extensive transverse myelitis (LETM) ratio (48.0％ vs.66.7％),NMOSD specific intracranial lesions ratio (32.0％ vs.53.3％),positive autoimmune antibody ratio (52.0％ vs.20.0％) (P=0.13,0.08,0.25,0.18,0.06,respectively).The thickness of temporal,superior,nasal,inferior and average RNFL in ON eyes of both Ab+/ NMOSD and Ab-/NMOSD group were thinner than those in eyes of HC group (all P＜0.05).The thickness of superior and inferior RNFL in ON eyes of Ab+/NMOSD were 61.0 μm and 62.0 μm,which was thinner than those of Ab-/NMOSD 94.5 μm and 97.0 μm (P=0.03 and 0.01,respectively).Conclusions RNFL reflects the injury of retinal microstructure in NMOSD patients.AQP4 Ab seropositivity is correlated to the severity of RNFL damage,implying the potential role of AQP4 Ab in this pathological process.

Objective To investigate the epidemiological characteristics of cerebral palsy(CP)in children aged 1-6 years in China,including the incidence,prevalence,type of CP,etiology,prevention and rehabilitation status. Methods The survey was carried out by standard questionnaires,multi-center collaboration,stratified-cluster ran-dom sampling method.The surveyed adopted the following principles:streets in the city and villages in the rural areas, and the number of the urban and rural children was the same,and the proportion of children in each age group was balanced.The investigation areas included provinces and autonomous regions,including Heilongjiang,Beijing,Henan, Shandong,Shanxi,Shaanxi,Anhui,Hunan,Guangxi,Guangdong,Chongqing and Qinghai,and 323 858 children were in-vestigated.Results The incidence of CP was 2.48‰(155/62 591 cases),and the prevalence was 2.46‰(797/323 858 cases)(1-6 years old).The prevalence varied in different regions,in which the highest prevalence was 5. 40‰(54/9 998 cases)in Qinghai province,and the lowest prevalence was 1.04‰(47/45 133 cases)in Shandong province.The prevalence of the males(2.64‰,461/174 391 cases)was higher than that of the females(2.25‰, 336/149 467 cases),and the difference was statistically significant(P<0.05).The types of CP were spastic type (58.85%,469/797 cases),mixed type(13.17%,105/797 cases),dyskinetic(9.79%,78/797 cases),hypotonic (8.28%,66/797 cases),ataxia(6.25%,52/797 cases)and rigid(3.39%,27/797 cases)respectively in 797 CP children.The first three risk factors for CP were long -term exposure to harmful physical factors during pregnancy, whether there were birth defects among the three generations of relatives of the children,such as children's peers, parents or grandparents,whether there were birth defects among the children's peers,parents or grandparents,and neonatal jaundice or persistent jaundice.Among 797 CP children,79.67% of the children with CP were timely detected and treated in the local hospitals,while the other 19.93% of them were not timely treated.The places which could give them timely detection and early diagnosis and treatment were general hospitals(42.97%),Maternity and Infant Hospitals (27.03%)and Children's Hospitals(20.31%). The main rehabilitation methods for 797 children with CP were 34.58% in the hospitals or rehabilitation centers,31.61% in the communities(including at home),33.80% mainly in the medical institution,and in the communities they could also receive partially rehabilitation services. Conclusions The prevalence of CP in China is coincident with international levels.The prevalence rate of CP in males is higher than that in females.The types of CP distribution are accorded with international distribution characteristics.There were still some children with CP who could not receive timely detection and treatment.Rehabilitation at the medical institutions is the chief way and proper rehabilitation guidance should be carried out in the communities.

Objective To explore the clinical characteristics of the neuromyelitis optica spectrum disorders (NMOSD) with the area postrema syndrome as the initial symptom.Methods A total of 14 cases were enrolled in the study with the diagnose of NMOSD and the area postrema syndrome as the initial symptom.All the clinical data and imaging profiles by the contrasted magnetic resonance imaging (MRI) of the head and spinal cord were collected and analyzed.Results The median age of onset was (38.1 ± 17.0)years old and the gender ratio of female to male was 10:4.The serum aquaporin-4 (AQP4)-IgG was positive in 11 subjects and several autoimmune antibodies was positive in 7 subjects.The lesions revealed by MRI of the head mainly located in the area postrema and ependymal periphery which often presented as the linear medullary lesion,while linear lesions over three pieces of vertebra were shown by MRI of the spinal cord which mainly in the grey matter and with aH shape around the spinal central canal.Misdiagnose happened in 11 subjects with seven of gastroesophageal reflux disease,two of neurogenic vomiting,one of spinal cord tuberculosis and one of stroke.Conclusions NMOSD should be considered in patients with unexplained intractable nausea,vomiting and/or hiccups lasted for 48 hours or above,especially in those with positive nervous signs.Contrasted MRI and serum AQP4-IgG need to be performed in the suspected patients.Early detection is crucial for patients with NMOSD.

Objective To investigate how to improve the survival rate,and to avoid the serious complications in fat grafting.Methods Under comprehensive design of facial filling area,the fat was harvested by concentration in mesh;under the micro autologous fat transplantation gun with blunt needle injection technique,the fat was filled into the face to achieve the effect of improving the facial contour and the rejuvenation.From June 2014 to July 2015,78 patients with facial contour and facial soft tissue relaxation depression were treatment by the technique.Results The follow-up of 2 months to 1 year showed that 64 patients had the soft,young,significantly enhanced facial contour;7 patients had second times grafts and the remaining were satisfied.7 patients gave up the second times grafts because the other reasons.The surgical complications such as facial nerve injury and infection and embolism were not seen.Conclusions This technique by comprehensive design and purification of autogenous fat granules achieves a better effect on facial rejuvenation with fewer complications.

Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure. Methods During the period from July 2011 to Oct. 2013, a total of 45 patients with pure ostium secundum defect were admitted to authors’ hospital to receive percutaneous transcatheter closer. The patients were divided into ASD without pulmonary hypertension (PH) group (group A, n = 28) and ASD with PH group (group B, n = 17). By using 3-D echocardiography and right cardiac catheterization, the right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV), right ventricular ejection fraction (RVEF), right ventricular cardiac output (RVCO), pulmonary artery systolic pressure (PASP) and the mean pulmonary artery pressure (mPAP) were determined before and after the percutaneous transcatheter closer. The results were compared between the two groups. Results After the treatment a statistically significant reduction in RVEDV, RVESV, RVSV and RVCO were seen in all patients (P < 0.05). In group A, RVEF decreased significantly after ASD closure when compared with that determined before transcatheter closer (P < 0.05), while no significant reduction in RVEF was seen in group B (P > 0.05). Pulmonary artery pressure (PAP) decreased significantly in group B after ASD closure when compared with that obtained before Objective To evaluate the changes of right ventricular (RV) volume and function by using single beat real-time three dimensional (3-D) echocardiography in patients with atrial septal defect (ASD) before and after percutaneous closure.

Pulmonary artery pressure (PAP) decreased significantly in group B after ASD closure when compared with that obtained before transcatheter closer (P < 0.05). Conclusion Single beat real-time 3-D echocardiography is a newly-developed technique. This technique can quickly and accurately assess the right ventricular volume and function. Right ventricular volume will decrease after ASD closer. In ASD patients without PH the right ventricular function will decrease after ASD closer, while in ASD patients with PH the right ventricular function shows no changes after ASD closer although their PAP will decrease.

Objective To explore the role of brain-derived neurotrophic factor (BDNF) in pathogenesis of autism. Methods 12.5 d pregnantWistar rats were injected sodium valproate (VPA) 600 mg/kg or normal saline (NS). Their newborn rats were observed ethologically.The expression of BDNF was measured in their temporal cortex with immunohistochemical stain. Results Compared with NS group, VPAgroup expressed less body mass (P<0.05), eyes opening delay (P<0.05), poorer coordination response (P<0.05), slower taxis response (P<0.05). The number of social behavior decreased (P<0.05), latency increased (P<0.05), duration shortened (P<0.05), repetitive activities increased(P<0.05). Purkinje cells reduced in cerebellum. The expression of BDNF increased significantly in temporal cortex 1 d, 7 d and 14 dpostnatally (P<0.01), but decreased 35 d and 49 d postnatally (P<0.01). Conclusion BDNF plays a role in the pathogenesis of autism.
