Objective To explore dyslipidemia in the people in the part of enterprises in Beijing.Methods Total cholesterol, triglyceride, high-density lipoprotein cholesterol, etc., in blood were detected in the physical examination of 12908 subjects in enterprises in Beijing. Dyslipidemia was analysed for the distribution of gender and the trend of age.Results The findings showed that the occurrence of hypercholesteremia is 21.3% with 20.3% for male vs 23.0% for female; hypertriacylglycerolemia is 30.4% with 36.19% for male vs 20.49% for female; and low level of high-density lipoprotein is 6.5% with 9.4% for male vs 1.6% for female. The trend of dyslipidemia increased with age. The subjects with coronary artery disease and related high risk diseases, who need medicine care, occupied 80.6% of the subjects with dyslipidemia.Conclusion Dyslipidemia increases with age and so regular detection of lipid is necessary especially for the subjects with coronary artery disease and related high risk diseases.

Objective To assess the efficiency of an iontophoresis-based screening method (EZSCAN) in the detection of impaired glucose tolerance (IGT),diabetes mellitus (DM) and metabolic syndrome (MS).Methods A total of 166 subjects without medical history of dysglycaemia underwent fasting plasma glucose (FPG) and HbA1c measurement and oral glucose tolerance test (OGTT) by using traditional or EZSCAN method.Variance analysis (GLM),SNK analysis,logistic regression analysis,and ROC analysis were used to evaluate the diagnostic value of those screening techniques.Results DM,IGT,normal glucose tolerance (NGT) +MS,and NGT were found in 4,26,25 or 111 participants,respectively.For traditional test,FPG of 7.0 mmol/L showed a lower sensitivity to detect DM (0%).The sensitivity of EZSCAN to detect DM,IGT or MS was 50%,77% and 64%,respectively.Conclusions FPG may have lower sensitivity to detect DM,although EZSCAN could show higher sensitivity to detect IGT,DM,and MS.

Objective To investigate the relationship of lower urinary tract symptoms (LUTS)with ageing in elderly population of Beijing. Methods From January 2010 to July 2010, the males over 40 years of age, who came to take routine health examination in Beijing Hospital, received a questionnaire related to urinary symptoms. Eligible men were classified into age groups spanning 10 years, and the urinary symptoms of each group were analyzed. Results Among the 2357 males who were investigated, the incidence of urinary symptoms increased, and the satisfaction of urinate decreased with ageing. In 40-49 age group, 44.94 % of males owned at least one urinary symptom and 71.47% of males were satisfied with their symptoms. In over-80 age group, these figures were 94.97% and 27.67%, respectively. Each symptom was associated with the satisfaction. Nocturia was the commonest symptom in each age group. Conclusions LUTS are common in elderly males and the incidence increases with ageing. Nocturia is the commonest symptom in elderly males.

To identify acute renal allograft rejection biomarkers in human serum, two-dimensional differential in-gel electrophoresis (2-D DIGE) and reversed phase high-performance liquid chromatography (RP-HPLC) followed by electrospray ionization mass spectrometry (ESI-MS) were used. Serum samples from renal allograft patients and normal volunteers were divided into three groups: acute rejection (AR), stable renal function (SRF) and normal volunteer (N). Serum samples were firstly processed using Multiple Affinity Removal Column to selectively remove the highest abundance proteins. Differentially expressed proteins were analyzed using 2-D DIGE. These differential protein spots were excised, digested by trypsin, and identified by RP-HPLC-ESI/MS. Twenty-two differentially expressed proteins were identified in serum from AR group. These proteins included complement C9 precursor, apolipoprotein A-IV precursor, vitamin D-binding protein precursor, beta-2-glycoprotein 1 precursor, etc. Vitamin D-binding protein, one of these proteins, was confirmed by ELISA in the independent set of serum samples. In conclusion, the differentially expressed proteins as serum biomarker candidates may provide the basis of acute rejection noninvasive diagnosis. Confirmed vitamin D-binding protein may be one of serum biomarkers of acute rejection. Furthermore, it may provide great insights into understanding the mechanisms and potential treatment strategy of acute rejection.

AIM:To explore the mechanisms behind the inhibition of lymphangiogenesis in pregnant rats with obstructive nephropathy and assess the protective effects on kidney function.METHODS:Forty nulliparous female Wi-star rats were randomly assigned to four groups:sham operation,sham operation+pregnancy,model,and Esaxerenone groups,with 10 rats in each group.Renal injury was induced in the model and Esaxerenone groups via unilateral ureteral obstruction(UUO).The other two groups underwent ureteral dissociation without ligation.Nine weeks post-UUO,female rats in the sham operation+pregnancy,model,and Esaxerenone groups were mated with male rats(2:1 ratio)to establish a rat model of obstructive nephropathy during pregnancy.Starting the day after UUO,rats in the Esaxerenone group re-ceived Esaxerenone at 1 mg·kg-1·d-1.On the 18th day of pregnancy,24-hour urine was collected using metabolic cages.The following day,the rats were sacrificed,serum samples collected,and the contralateral kidney removed.Blood urea ni-trogen(BUN)was measured using standard biochemical methods,and endogenous creatinine clearance rate(Ccr)was calculated.Kidney tissue pathology was assessed using HE,Masson,and Sirius red staining.Serum aldosterone levels were determined via ELISA.Immunohistochemistry,real-time PCR,and Western blot were employed to assess mineralo-corticoid receptor(MR)activation,lymphangiogenesis,signaling pathways,and fibrosis-related markers.RESULTS:Renal function tests revealed increased BUN levels and decreased Ccr in the model group(P<0.01).Pathological exami-nation showed dilated renal tubules,significant collagen deposition,and inflammatory cell infiltration in the model group.ELISA results indicated a significant increase in serum aldosterone levels in the model group(P<0.01).Immunohisto-chemistry showed enhanced nuclear translocation of MR in the kidneys of the model group post-activation.Western blot and real-time PCR demonstrated a marked increase in neutrophil gelatinase-associated lipocalin(NGAL)expression in the model group(P<0.01).Additionally,the expression of vascular endothelial growth factor C(VEGF-C)and its receptor VEGFR3 was significantly elevated in the renal tubulointerstitium of the model group,as shown by both immunohistochem-istry and real-time PCR(P<0.01).The PI3K/Akt signaling pathway was activated in the model group,with significantly increased phosphorylation levels observed primarily in renal tubular epithelial and interstitial cells(P<0.01).Collagen type III(Col III)expression,primarily in the renal tubulointerstitium,was also significantly upregulated in the model group,consistent with real-time PCR results(P<0.01).Esaxerenone treatment improved renal function,reduced patho-logical damage,inhibited aldosterone secretion,and downregulated the expression of MR,NGAL,VEGF-C,VEGFR3,phosphorylated PI3K,phosphorylated Akt,and Col III(P<0.01).CONCLUSION:Esaxerenone mitigates aldosterone-induced MR activation,modulates the PI3K/Akt signaling pathway,reduces lymphangiogenesis in the contralateral kidney of pregnant rats with obstructive nephropathy,decreases collagen deposition,and delays the progression of renal intersti-tial fibrosis.

Pulmonary adenocarcinoma in situ is reclassified as precursor glandular lesions in the fifth edition of WHO classification of thoracic tumours, causing widespread attention and heated debate among domestic thoracic oncologists, radiologists, pathologists and surgeons. We would like to comment on the topic and make a few suggestions on the management of pulmonary nodule during lung cancer screening. We are open to all suggestion and welcome debates.

Background and objective As computed tomography (CT) screening for lung cancer becomes more common in China, so too does detection of pulmonary ground-glass nodules (GGNs). Although anumber of national or international guidelines about pulmonary GGNs have been published,most of these guidelines are produced by respiratory, oncology or radiology physicians, who might not fully understand the progress of modern minimal invasive thoracic surgery, and these current guidelines may overlook or underestimate the value of thoracic surgery in the management of pulmonary GGNs. In addition, the management for pre-invasive adenocarcinoma is still controversial. Based onthe available literature and experience from Shanghai Pulmonary Hospital, we composed this consensus about diagnosis and treatment of pulmonary GGNs. For lesions which are considered as adenocarcinoma in situ, chest thin layer CT scan follow-up is recommended and resection can only be adopt in some specific cases and excision should not exceed single segment resection. For lesions which are considered as minimal invasive adenocarcinoma, limited pulmonary resection or lobectomy is recommended. For lesions which are considered as early stage invasive adenocarcinoma, pulmonary resection is recommend and optimal surgical methods depend on whether ground glass component exist, location, volume and number of the lesions and physical status of patients. Principle of management of multiple pulmonary nodules is that primary lesions should be handled with priority, with secondary lesions taking into account.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.
