OBJECTIVE: To investigate the effect of chronic emotional stimulation induced by empty bottle stimulation on CXCL12/CXCR4-mediated inflammatory response in rats with acute myocardial infarction (AMI). METHODS: Rat models of anxiety were established by a 21-day stimulation with uncertain empty bottle drinking water, and myocardial infarction was induced by ligating the left anterior descending branch of the coronary artery; compound models were established by performing myocardial infarction operation on the 15th day of anxiety modeling. The rats were randomly divided into 4 groups: shamoperated group (=6), myocardial infarction group (=6), compound model group (with myocardial infarcted and anxiety; = 6), and inhibitor group (compound models treated daily with 1 mg/kg AMD3100 for 6 days; =7). Echocardiography was used to examine the LVEF and LVFS to evaluate the cardiac function of the rats. Elevated maze test and open field test were used to evaluate the behaviors of the rats. The expressions of CXCL12, CXCR4, IL-1β, IL-18 and neutrophil active protease (NE) in the myocardial tissues and blood samples were detected with ELISA and immunohistochemistry. RESULTS: The LVEF and LVFS were lower in the compound model group than in the sham group and myocardial infarction group ( < 0.05), and were higher in inhibitor group than in the compound model group ( < 0.05). LVID; d and LVID; s were lower in the inhibitor group than in the compound model group ( < 0.05). Compared to those in the sham group and myocardial infarction group, the rats in the compound model group more obviously preferred to stay in the closed arm ( < 0.05) in EPM; the rats in the inhibitor group had more times of entering and staying in the open arm than the compound model rats ( < 0.05); the horizontal and vertical movements were less in the compound model rats than in those in the sham group and the myocardial infarction group ( < 0.05) in OFT, and the vertical movement of the rats in inhibitor group was higher than those in the compound model group ( < 0.05). The expression of CXCR4 in the marginal zone of myocardial infarction was significantly higher in the compound model group than in the sham-operated group, myocardial infarction group and inhibitor group ( < 0.05). The expressions of IL-1β, IL-18 and NE in the inhibitor group were significantly lower than those in the compound model group ( < 0.05). Compared with at in the sham-operated group, the number of Nissl bodies in the compound model group decreased significantly ( < 0.01). CONCLUSIONS Chronic emotional stress induced by empty bottle stimulation can lead to dysfunction of the CXCL12/CXCR4 axis, which causes inflammatory cascade after myocardial infarction to worsen myocardial cell necrosis, cardiac function and hippocampal neuronal damage after the infarction.

Objective:To report for the first time the clinicopathologic characteristics of two patients with light chain deposition disease after renal transplantation.Methods:The clinicopathologic features were analyzed for two patients with light chain deposition disease and the related literature was reviewed.Case 1 was a 49-year-old male with unknown primary disease presenting with abnormal urine test and elevated serum creatinine at 24 months after kidney transplantation. Renal allograft biopsy hinted at light chain deposition disease. Case 2 was a 38-year-old male with light chain deposition disease in native kidneys presenting with proteinuria, microscopic hematuria and elevated serum creatinine at 15 months after kidney transplantation. Renal allograft biopsy supported recurrent light chain deposition disease.Results:1 case after bortezomib and dexamethasone dosing, serum creatinine decreased during follow-ups. 1 case received bortezomib and dexamethasone. However, sepsis and pulmonary infections developed and allograft function deteriorated.Conclusions:Light chain deposition disease after renal transplantation is a rare disorder with a rapid progression and a poor prognosis. Early detection of free light chain in blood and urine through immune fixed electrophoresis is conducive to an early diagnosis. The efficacy of bortezomib is to be furthered examined.

Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.

Objective To study the clinical characteristics,cardiac magnetic resonance (CMR)features,and genetype of hypertrophic cardiomyopathy (HCM) in neonates.Method HCM newborns diagnosed at pediatric department of Anzhen Hospital Affiliated to Capital Medical University from January 2015 to December 2018 were retrospectively collected.The clinical manifestations,imaging features and genetype were analyzed.Result During the study period,there were 11 227 deliveries and 11 397 live births.52 of the parturient women were diagnosed as HCM before or during pregnancy (0.46％,52/11 227).54 neonates were delivered from HCM mothers.Among them,5 were diagnosed as HCM (5/11 397,0.04％).In addition,there was another infant patient who was admitted from another hospital.In total,6 HCM infants were included in this study,with 4 males and 2 females.The average gestational age of the infants was (36.6 ± 1.2) weeks,with 3 preterm infants,and the others were full-term infants.The median age of diagnosis was 1 day.The clinical manifestation was that 4 patients needed rest in the course of suckling,3 of them also had accompanied symptoms,with pale face,cyanosis while crying and sweating in each case.CMR showed that the ventricular septum was (6.80 ± 1.78)mm,ejection fraction was (60.0 ± 2.8)％.All six patients showed septal thickening on CMR,including a case with right ventricular myocardial hypertrophy,another with left ventricular outflow tract obstruction and late gadolinium-enhanced.The infants were all treated with metoprolol.They were followed up until 6 months to 2 years old.Among them,4 cases had no progress in myocardial thickening.Two cases had progressive myocardial thickening,one of them was diagnosed as end-stage HCM at 2 year-old.Three MYBPC3 mutations,one MYH7 gene mutation,one MYH7 gene mutation combined with TMPO gene mutation and one RYR2 gene mutation were detected.Conclusion The neonatal HCM is characterized by thickening of ventricular septum,outflow tract obstruction and delayed enhancement of CMR.The most common HCM mutations were MYBPC3 and MYH7,the most common clinical symptoms were breast feeding interruption,followed by cyanosis,pale and sweating.It is suggested that beta-blockers should be recommended for neonates with hypoxic episodes or outflow tract obstruction.

Objective To analyze the epidemiological characteristics and influence factors of human brucellosis in Jilin Province and provide scientific basis for enacting prevention and control strategy to brucellosis in the new period.Methods Descriptive epidemiological methods were used to analyze the epidemiological characteristics (regional distribution,time distribution,population distribution,etc.),influencing factors (risk factors,protective measures and epidemic prevention),epidemic links,detection methods,clinical stages and prognosis of reported brucellosis cases in Jilin Province from 2011 to 2017.Results From 2011 to 2017,12 116 cases of brucellosis were reported in Jilin Province,with an average incidence of 6.30/100 000.The annual incidence rates were 7.51/100 000,7.11/100 000,7.36/100 000,6.58/100 000,5.90/100 000,5.38/100 000 and 4.24/100 000,respectively.The reported cases were mainly distributed in Songyuan City and Baicheng City,accounting for 73.29％ (8 880/12 116) of the total number of reported cases;the time was from January to July,and the peak was from March to May.The age of onset ranged from 20 to 70 years old,mainly in young and middle-aged adults,accounting for 95.86％ (11 615/12 116) of the total number of reported cases.The following factors were studied:to take protective measures rate,human and animal mixed live,the same water source,colony house housing disinfection,manage abortion,buy animal quarantine,raise livestock immunity,and the proportion of these factors in each year was 24.38％ to 43.33％,3.11％ to 17.35％,63.68％ to 76.58％,25.40％ to 35.07％,21.66％ to 34.49％,9.32％ to 29.66％,26.09％ to 45.45％,respectively.The main infection source was sick sheep,accounting for 96.72％ (11 718/12 116).Skin mucosa was the main route of transmission,followed by digestive tract,accounting for 61.55％ (7 458/12 116) and 34.17％ (4 140/12 116),respectively.The main transmission factors were apoblema and flying dust,accounting for 55.68％ (6 746/12 116) and 35.62％ (4 316/12 116),respectively.The number of reported cases of brucellosis was 90.55％ (10 971/12 116) through passive monitoring.The clinical stage was mostly acute,accounting for 92.01％ (11 148/12 116).Healing and improvement accounted for 60.80％ (7 367/12 116) and 37.93％ (4 596/12 116),respectively.Conclusions Brucellosis has dropped slightly in Jilin Province in 2011-2017,but remains high;the epidemic situation is still grim.We should further strengthen monitoring,health education and health promotion,team construction,in order to effectively control the occurrence of human brucellosis.

In the past two years, a line of basic and genetic findings have been produced in the field of type 2 diabetes. Some evidence has suggested that mature β cell under long-term metabolic stress could de-differentiate into pre-endocrine cells and re-differentiate into α and PP endocrine cells. Several key factors were reported with genetic modified animal models in the past two years. A novel adipokine, Asprosin was found to control insulin resistance and food intake in both humans and mice. Additionally, researchers reported that gut microbiota was associated with the development of type 2 diabetes, and a few bacteria or certain enterotype could be valuable in the prediction of prevention and clinical intervention for diabetes. The genetic composition for missing heritability of type 2 diabetes and obesity was revealed with the next-generation sequencing strategy. Importantly, scientists at home and abroad made a significant progress in the field during the past few years, which should be reviewed here. (Chin J Endocrinol Metab, 2018, 34: 605-609)

A 72-year-old female patient was admitted to our hospital due to chronic cough, expectoration and dyspnea for 10 years,aggravated with intermittent fever for 1 month. She was diagnosed as acute exacerbation of chronic bronchitis,chronic pulmonary heart disease,cardiac function class IV,bilateral lower extremity venous thrombosis and thrombocytopenia. The application of antico-agulant drugs and coagulant drugs in the patient needed to be well weighed with the methods of the bleeding score system combined with clinical assessment of actual risk of bleeding. The interactions of drugs harmful to the patient should be considered and the prognosis of the patient should also be evaluated with careful clinical thought to reduce the patient's risk.

OBJECTIVE: To determine the feasibility of reduced field-of-view diffusion-weighted imaging (rFOV DWI) with multi-b values to detect functional variability in transplanted kidneys. MATERIALS AND METHODS: Using a 3T MRI scanner, multi-b rFOV DWI of transplanted kidney or native kidney was performed in 40 renal transplantation recipients and 18 healthy volunteers. The patients were stratified, according to an estimated glomerular filtration rate (eGFR): Group 1, eGFR ≥ 60 mL/min/1.73 m2; Group 2, eGFR ≥ 30 mL/min/1.73 m2 and < 60 mL/min/1.73 m2; Group 3, eGFR < 30 mL/min/1.73 m2. Total apparent diffusion coefficient (ADCT), perfusion-free ADC (ADCD) and perfusion fraction (FP) of kidneys were calculated and compared among the four groups. Correlations between the imaging results and eGFR were assessed. RESULTS: All volunteers had eGFR ≥ 60 mL/min/1.73 m2, while 16, 16, and 8 patients were included in Groups 1, 2, and 3, respectively. In the renal cortex, ADCT was higher in Group 1 ([1.65 ± 0.13] × 10−3 mm2/s) than Group 3 ([1.44 ± 0.11] × 10−3 mm2/s) (p < 0.05), and the inter-group differences of FP values were significant (all p < 0.05) (0.330 ± 0.024, 0.309 ± 0.019, 0.278 ± 0.033, and 0.250 ± 0.028 for control group, Groups 1, 2, and 3, respectively). Renal cortical ADCT, ADCD, FP, and renal medullary ADCT and FP correlated positively with eGFR (r = 0.596, 0.403, 0.711, 0.341, and 0.323, respectively; all p < 0.05). When using 0.278 as the cutoff value, renal cortical FP had a sensitivity of 97.1% and a specificity of 66.7% for predicting decreased renal function. CONCLUSION: Multi-b rFOV DWI presents transplanted kidneys with high resolution, which is a promising functional tool for non-invasively monitoring function of transplanted kidneys.
