Objective Objective To explore the reasons of lung hypervolemia after liver transplantation and the corresponding treatment strategies.Method 291 patients received liver transplantation,in which 35 cases underwent pulmonary edema at early stage (pulmonary hypervolemia group),and the rest without pulmonary hypervolemia served as control group.Average central venous pressure (CVP) was recorded pre-,intra-and post-operatively.Total intake,total discharge and fluid balance were also recorded intraoperatively and 3 days post-operatively.Result In pulmonary hypervolemia group,CVP was (12.33 ± 5.08),(14.33 ± 3.03) and (16.50 ± 4.57) mmHg pre-,intra-and post-operatively,significantly higher than that in control group (P＜0.05 for all).Total intake,total discharge and fluid balance in pulmonary hypervolemia group were significantly higher than those in control group intraoperatively and 3 days post-operatively (P＜0.05 for all).After diuretic therapy and hemodialysis,30 cases in pulmonary hypervolemia group recurred,and 5 cases died of infection.Conclusion Pulmonary hypervolemia at early stage after liver transplantation is related to fluid balance.The reasonable control of total intake,total discharge and fluid balance is necessary.

ObjectiveTo evaluate the priority application of thin adrenal CT scanning in out-patients with hypertension for early diagnosis of adrenal hypertension.MethodsThe patients with hypertension were collected from January to August 2009,in whom the secondary hypertension ( including endocrine and renal hypertension) and malignant cancers were excluded.All patients accepted the adrenal CT scan firstly,and then the patients with the positive result of morphological abnormalities in the adrenal CT( including adenoma and hyperplasia)were evaluated for endocrine function of adrenal glands.Results A total 362 cases of hypertension were studied,in.cluding 162 males and 200 females.The average age was (60.9 ±9.3 ) year-old,the average duration of hypertension was ( 13.8 ±5.3 ) year.After adrenal thin layer scanner CT scan,35 patients ( 9.6％ ) with adrenal abnormalities were found.Endocrine functional assessments of adrenal glands were carried out among these patients,17 cases (4.7％) with functional lesions were diagnosed,including 14 cases(3.9％ )with primary hyperaldosteronism,2 cases(0.6％ )with Cushing's syndrome,and 1 case ( 0.3％ ) with pheochromocytoma.Conclusion This study revealed that the percentage of adrenal lesions in outpatients with hypertension was 9.6％.The percentage of adrenal hypertension was 4.7％.Thin layer CT scan seems to effectively screen the adrenal hypertension with adrenal lesions,and would be helpful to the diagnosis of endocrine hypertension.

Aim To investigate ALEX1 gene expres-sion in cervical cancer tissues and adjacent non-can-cerous tissues, and to explore the ALEX1 genetic influ-ence on cell proliferation,cycle and apoptosis of human cervical cancer cell line HeLa. Methods ALEX1 protein expression in cervical cancers and in non-can-cerous cervical tissues was evaluated using immunohis-tochemical method. A small interference RNA targeting ALEX1 gene was transfected into HeLa cells′, and the effect of ALEX1 interference on HeLa cells′ cycle and apoptosis was analysed by flow cytometry. The effect of ALEX1 interference on HeLa cells′ proliferation and sensitivity to resveratrol was analysed by CCK-8 assay. Results ALEX1 protein expression was significantly increased in cervical cancer tissues compared with non-cancerous tissues. HeLa cells′proliferation was inhibi-ted compared with control group and blank group. He-La cells′ sensitivity to resveratrol was enhanced com-pared with control group blank group. Conclution SiRNA silencing of ALEX1 gene could significantly in-hibit HeLa cells′ proliferation and enhance resveratrol ability of inhibiting HeLa cells′proliferation.

Objective To study the association of liver fat content (LFC) with insulin resistance and β cell function. Methods One hundred and nine subjects including 31 cases with impaired glucose regulation (IGR), 31 newly diagnosed type 2 diabetes (NT2DM) and 47 normal controls (NC) with normal metabolic parameters were involved in the study. LFC was measured by 1H magnetic resonance spectroscopy (1H MRS) and the insulin resistance and β cell function were evaluated by oral 75 g glucose tolerance test. Results (1 ) LFCs were3.83% (2.35% ～7.59% ) ,12. 82% (8.10%～21.37%), and 21.99% (11.89%～34.43%), being progressively raised in the respective NC, IGR, NT2DM groups(P<0.01). (2) The subjects were divided into four subgroups according to LFC Quartile: Quartile 1 (LFC<4. 04% ) , Quartile 2(4. 04% ≤LFC<9. 77% ), Quartile 3 (9.77% ≤LFC<20.78% ) ,and Quartile 4( LFC≥20.78% ). Homeostasis model assessment of insulin resistance index (HOMA-IR) values were elevated significantly and progressively starting from Quartile 2(P<0. 01). (3) Insulin from 0 to 30 min ( △I30), the ratio of insulin from 0 to 30 min to glucose from 0 to 30 min ( △I30/ △G30) , C peptide from 0 to 30 min (△CP30) had a trend of increase in Quartile 2,then trended to decrease in Quartile 3. In Quartile 4, △CP30 and △I30/△G30 sharply decreased (P<0.05 or P<0.01). The ratio of C peptide from 0 to 30 min to glucose from 0 to 30 min ( △CP30/△G30) began to decrease from Quartile 3 (P<0. 05). The ratio of area under curve of C peptide to area under curve of glucose (CPAUC/GAUC) was significantly decreased from Quartile 3(P<0.05). From Quartile 3,glucose level became abnormally elevated to impaired fasting glucose and impaired glucose tolerance (P<0.01). (4) LFC was positively correlated with HOMA-IR (rs =0. 618 ,P<0.01), but was negatively correlated with △CP30(rs =-0.282), △CP30/△G30(rs = -0. 404), and CPAUC/GAUC(rs = -0. 308,all P<0.01). (5) Stepwise regression analysis demonstrated that LFC was the strongest predictor of HOMA-IR. Conclusions When LFC accumulated to 4% , insulin resistance occurred and the early phase of insulin secretion was compensatively increased. As the LFC further accumulated to 10% , both the early phase as well as β cell function in whole were deteriorated, and hyperglycemia developed.

Objective To investigate the incidence and correlative factors of metabolic syndrome (MS) in patients with systemic lupus erythematosus (SLE).Methods A total of 116 SLE patients and 115 controls were enrolled into the study.The incidence of MS,SLE disease activity index(SLEDAI) of patients with SLE combined with MS (MS-SLE) and patients without MS (n-MS-SLE),lupus characteristics,cumulative glucocorticoids,administration dose of glucocorticoids and hydroxychloroquine were compared between SLE group and the control group.Results The incidence of MS of SLE group was obviously higher than that of the control ( 34.48％ vs 14.78％,P ＜ 0.05 ).The ratios of patients with lower HDL-C,higher TG and higher blood pressure in SLE group ( 50.86％,56.03％,46.55％ ) were higher than those in the controls ( 34.78％,16.52％,20.00％,all P ＜ 0.05 ).MS-SLE group had significantly higher mean waist circumference,BMI,systolic blood pressure and diastolic blood pressure and lower HDL-C than n-MS-SLE group (all P ＜0.05 ).No significant difference was found regarding duration of disease,renal involvement,ESR,C-reactive protein,high-sensitivity C-reactive protein,SLEDAI,cumulative and current glucocorticoids use in MS-SLE group and n-MS-SLE group.The ratio of patients taking hydroxychloroquine in n-MS-SLE group was higher than that of MS-SLE group (46.05％ vs 15.00％,P＜0.05).Conclusions Patients with SLE has a higher incidence rate of MS.Hydroxychloroquine may reduce their MS incidence.

This article reported a case of type 1 diabetes caused by a programmed death-1 ( PD-1) inhibitor. The patient was a 52-year-old man with metastatic renal cell carcinoma who received the combined therapy of PD-1 inhibitor Nivolumab and vascular endothelial growth factor ( VEGF) inhibitor Bevacizumab. He presented with thirst, polydipsia, polyuria, repeated vomiting, and fatigue 9 weeks after initiation of the therapy and developed into diabetic ketoacidosis (DKA) about 2 weeks later, with blood glucose 50.9 mmol/L, HbA1C8.4％, serum fasted and glucose-loaded C peptide<0.01 ng/ml, arginine test negative, and autoantibodies negative. The patient was diagnosed as type 1 diabetes caused by the PD-1 inhibitor and was given intensive glucose lowering treatment with insulin, water and electrolyte disorders were also corrected. His symptoms improved but he had to continue insulin treatment. It is recommended to check baseline glucose level prior to the initiation of treatment with PD-1 inhibitor, and should carefully monitor the clinical symptoms and glucose levels during the treatment. Timely detection, correct diagnosis and treatment are important to ensure patients' safety and to improve their prognosis.

Objective To study the value of fast dynamic contrast enhanced MRI in the diagnosis of orbital occupying lesions. Design Retrospective ease series.Participants 21 patients with orbital occupying lesions.Methods All the 21 patients were performed on fast dynamic contrast enhanced MRI and were verified by pathology.The raw datum were processed by the software of GE Functool. Parameters such as time-intensity curve(TIC),time to peak(Tpeak),1 minute enhancement ratio(ERlmin)and maximum enhancement ratio(ERmax)were analyzed to study the characteristics of orbital diseases on fast dynamic contrast-enhanced MRI.Main Outcome Measures TIC,ERlmin,and ERmax.Results The characteristics of TIC between benign diseases and malignant tumors were different. Of the 16 cases of benign lesions,12 demonstrated as continuous increasing type,and of 5 cases of malignant lesions,3 cases of lym- phoma were all platform type.The ER1min of the malignant tumors(150.47?42.18)was higher than that of the benign lesions (101.37?43.02)(P=0.021).Cavernous hemangiomas had special progressing enhancing model.Conclusions Fast dynamic contrast enhanced MRI is valuable to distinguish malignant tumors from benign occupying lesions.(Ophthalmol CHN,2007,16:305-308)

Objective To analyze the clinical factors for pathologic complete response ( pCR) after preoperative neoadjuvant chemoradiotherapy ( neo?CRT) for locally advanced rectal cancer. Methods From 2005 to 2012, 297 patients with locally advanced rectal cancer and complete clinical data were enrolled as subjects. Those patients were diagnosed with biopsy and treated with neo?CRT ( radiotherapy by 3?dimonsional conformal radiotherapy or volumetric?modulated arc therapy) followed by radical surgery. The logistic regression model was used for the multivariate analyses of the correlation of pCR with age, gender, distance between tumor and the anal verge, serum level of carcinoembryonic antigen ( CEA ) before treatment, hemoglobin level before treatment, cT staging, and cN staging. Results In all patients, 78 ( 26?7%) patients had pCR after treatment. The numbers of patients with pCR were 42( 34?4%) in patients with stage T1?T3 disease and 37(21?1%) in patients with stage T4 disease. In the patients with serum CEA levels no higher than 5?33 ng/ml, 55(36?4%) had pCR after treatment, while in the patients with serum CEA levels higher than 5?33 ng/ml, only 24( 16?4%) had pCR. The univariate analysis revealed that age, gender, distance between tumor and the anal verge, anemia before treatment, or cN staging were not related to pCR. The multivariate analysis showed that stage cT1?T3 and a serum CEA level no higher than 5?33 ng/ml before treatment were influencing factors for pCR after neo?CRT for locally advanced rectal cancer ( P=0?031,P=0?000) . Conclusions The clinical staging and the serum CEA level before treatment are influencing factors for pCR after neo?CRT for locally advanced rectal cancer. The serum CEA level before treatment can be considered as a predictor of pCR after neo?CRT for locally advanced rectal cancer.

Objective: To clarify the association between occupational exposure to wood dust and chronic obstructive pulmonary disease risk by a meta-analysis. Methods: A systematic search of the studies was conducted using 3 English databases (Pubmed, Embase, and Cochrane library) and 3 Chinese databases (CNKI, WanFang, and VIP) before March 2019. The following key words was used: 1) wood, 2) hardwood, 3) softwood, 4) saw, 5) dust, 6) chronic obstructive pulmonary disease, 7) chronic obstructive airway disease, 8) lung function. A quality score was evaluated by Newcastle-Ottawa Scale, NOS (Wells, 2012). Pooled effect value with 95% confidence interval (CI) was calculated using fixed-effect model (Heterogeneity test I²<25%) or random-effect model (Heterogeneity test I²≥25%). Meta-regression was used to explore heterogeneous source. Sensitivity analysis was used to verify the stability of the results. Publication bias was assessed by Egger＇s test. Fill and trim method was used to correct the pool effect value with 95%CI for studies which wit publication bias. The TSA threshold was calculated by the O＇Brien-Fleming loss function in the TSA data. The studies were evaluated based on the accrued information size (AIS) . Results: A total of 9 studies were included in the analysis. The occupational exposure to wood dust was not significantly associated with increased chronic obstructive pulmonary disease risk (ES=1.01, 95%CI: 0.856-1.194). TSA showed that the cumulative Z-value curve neither gone beyond the traditional (Z=1.96) threshold line, nor exceed the TSA threshold, but has reached the expected amount of information. This result was consistent with the meta-analysis. Conclusion This study does not yet consider that COPD is associated with occupational wood dust exposure.

OBJECTIVETo study the hepatoprotective effect of the extract of Terminala catappa leaves (TCE) and the possible mechanisms underlying its protection on acute liver injury induced by D-Galactosamine (D-GalN).

METHODIn vivo: D-GalN-induced liver injury model was used to evaluate the effect of TCE on the activities of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) in mice. Structure of liver was observed and liver mitochondrial swelling was measured following D-GalN injection without or with TCE. In vitro: D-GalN-induced primary cultured hepatocytes injury model was used to value the effect of TCE on cultured hepatocytes. Cell viability was measured by means of MTT assay, and the AST and superoxide dismutase (SOD) activities in supernatant of cultured cells were investigated also.

RESULTIn acute hepatic injury test, with oral pretreatment of TCE, remarkable rises in serum AST and ALT activities (2.95 fold and 3.35 fold) induced by D-GalN were obviously reversed and significant morphological changes were remarkably lessened. In addition, the decrease in sensitivity of mitochondrial swelling to the exotic Ca2+ stimulation induced by D-GalN was also prevented by TCE. In primary cultured hepatocytes of mice, it was found that incubation with TCE could prevent the decrease in cell viability in a dose-dependent manner. It was also found that both the increase in AST level (1.9 fold) and the decrease in SOD activity (48.0%) in supernatant of primary cultured hepatocytes induced by D-GalN could be inhibited by pretreatment of TCE.

CONCLUSIONTCE has hepatoprotective activity and the mechanisms underlying its protective effect may be related to its antioxidant activity and protection on both hepatocytes and liver mitochondria.
