Objective To investigate the relationship between serum cystain C,urinary neutrophil gelatinase?associated lipocalin(NGAL),uri?nary kidney injury molecule?1(KIM?1)and preeclampsia,and explore the value in predicting preeclampsia and early kidney damage. Methods A total of 30 cases of pregnant women with severe preeclampsia,30 cases of mild preeclampsia and 60 cases of healthy pregnant women admitted in the Second Hospital of Jilin University from October 2014 to July 2015 were enrolled for the study. ELISA was performed to check urinary KIM?1 and urinary NGAL,and the serum cystatin C was detected by immune turbidity method. Results KIM?1,NGAL,serum cystatin C in the preeclampsia were significantly higher than the normal control group(P<0.05). In addition,with the development of their concentrations,the progression of pre?eclampsia gradually rise;BMI,e?GFR,urine protein/creatinine ratio,KIM?1,serum scystatin C and NGAL are the risk factors for preeclampsia;uKIM?1,serum scystatin C and NGAL and combined predictors of preeclampsia are taken as the early indicators of renal injury,which sensitivity are separately 83.3%,75%,88.9%,96.8%;specificity are respectively 72.7%,70%,75.6%,86.4%. Conclusion KIM?1,serum scystatin C and NGAL may reflect the progression of renal injury in preeclampsia .Combined predictors have a higher predictive value in the early renal injury of the preeclampsia.

AIM:To observe the neuritogenic actions of botulinum neurotoxin serotype A heavy chain ( BoNT/A HC) on cultured Neuro-2a cells and to investigate the related signaling mechanisms for the effect of BoNT /A HC. METHODS:Neuro-2a cells were treated with different doses of BoNT/A HC (0.01, 0.1, 1 and 10 nmol/L), and then the cells were harvested at 24 h, 48 h and 72 h of BoNT/A HC exposure for detecting the neurite length and the percen-tage of the cells with neuronal processes by immunofluorescence staining .The most efficient dose of BoNT/A HC was cho-sen for exposure to Neuro-2a cells as the above.Whole cell protein was harvested at different time points for detecting the protein levels of phosphorylated ERK 1/2 ( p-ERK1/2 ) and phosphorylated Akt ( p-Akt ) by Western blot .RESULTS:Low doses of BoNT/A HC stimulated the neurite outgrowth , and increased the percentage of the cells with neurites com-pared with the negative controls (P<0.05), especially in the group with 1 nmol/L of BoNT/A HC treatment.Meanwhile, the phosphorylation of ERK 1/2 and Akt was increased after treated with BoNT/A HC.There was an increasing tendency for the phosphorylation of ERK1/2 after the exposure of the cells to BoNT/A HC.The obvious increase in p-ERK1/2 was seen from 60 min to 5 h with 1 nmol/L of BoNT/A HC treatment ( P<0.05 ) , and the increased protein level of p-Akt was mainly observed at 15 min and 60 min ( P<0.05 ) .CONCLUSION: BoNT/A HC stimulates the neuritogenesis .The neuritogenic mechanism of BoNT/A HC on Neuro-2a cells might be realized by activation of the phosphorylation of ERK 1/2 and Akt.

The present study aims to investigate the kinetic histocytochemical changes of acupoints in different condition. The expression of tryptase (+) mast cells, histamine (HA) , serotonin (5-HT) and nociceptive neuropeptides including calcitonin gene-related peptide (CGRP) and substance P (SP) were observed by immunohistochemistry combined with confocal technology. Mast cells were labeled with anti-mast cell tryptase antibody and simultaneously with HA or 5-HT primary antibodies to observe their co-expression. The results showed that: (1) SP and CGRP were expressed more highly on the cutaneous nerve fibers of "Hegu" (LI 4) after acupuncture stimulation than that of the control. Mast cells aggregated in close proximity to the blood vessels in intra-epidermis and dermis, and some of them with degranulation in the lower dermis and subcutaneous tissue of "Hegu" (LI 4). Both mast cells and their granules appeared with HA (+) and 5-HT (+) expression at stimulated LI 4 sites, while a few intact mast cells with a little expression of 5-HT and HA were distributed in areas of non-stimulated Ll 4. (2) The acupoints in different locations such as Baihui (GV 20), Weishu (BL 21), Zhongwan (CV 12) and LI 4 had the same constituent but the contents were different. (3) The histocytochemical responses of acupoints sensitized by the Gastric mucosa injury (GMI) were also investigated. GMI resulted in neurogenic plasma extravasation by Evans Blue (EB) in the skin of the acupoints over the back and abdomen, which mostly occurred in the T9-T11 dermatomere. The EB extravasation dots just like acupoints sensitization appeared after GMI and disappeared gradually during the natural self-recovery of the gastric mucosa. More SP and CGRP positive nerve fibers were distributed in EB dots than in regions beside EB dots and in the control, mostly distributed in the nerve fibers around both the vessels and root of hair follicle. Mast cells also aggregated and degranulated to release algogenic substances of 5-HT and HA around the vessels in areas of the EB dots. Collectively the acupoints displayed the same histocytochemical responses due to either acupuncture stimulation or GMI. This may potentially be the histocytochemical basis in the local acupoints and acupoints displayed kinetic changes in different condition.

Objective To study the relationship between the genetic polymorphism of interleukine-6 (IL-6)-174 and the response to benazepril treatment in patients with hypertensive renal damage. Methods Two hundred and eighty-four patients with hypertension were enrolled in this study. The hypertensive renal damage was defined by the measurement of urinary albumin excretion rate (UAER). One hundred and sixty healthy subjects were enrolled simultaneously as control group. Blood samples were obtained from all the subjects, and plasma levels of IL-6 and the genotype of gene IL-6-174 were detected. The patients with hypertensive renal damage were treated with benazepril for 16 weeks. The responses were evaluated by the changes of UAER level to benazepril in different genotypes. Results Genotype CC was the most common of the gene IL-6-174 in patients with hypertension, followed by GG and GC successively, with the G/C allele frequency of 47%and 53%(P<0.05), while in patients with hypertensive renal damage, GG was the most common genotype of the gene IL-6-174, followed by GC and CC successively, with the G/C allele frequency of 68%and 32%(P<0.05). After benazepril treatment, the UAER was decreased most in patients with genotype CC, followed by GC and GG successively ( P<0.05). Conclusion The G allele frequency of the gene IL-6-174 is related with hypertensive renal damage in patients in Ningxia, with GG as the most common genotype. The patients with CC genotype have the best response to benazepril treatment, with most decreased UAER.

Objective To observe hemodynamic changes in patients with primary hypertension with wave intensity (WI). Methods Carotid arteries of 36 patients with primary hypertension and 30 age-matched normal controls were examined with imaging technique of WI. The following parameters were measured: the first wave peak in early ejection (W1), the second wave peak in late ejection (W2), the negative area during the mid-ejection (NA), the interval between the R wave of the ECG and the first peak of W1 (R-1st), the interval between the first peak and the second peak (1~(st)-2~(nd)), the ratio of R-1st and a cardiac cycle time R-1_(HR)~(st)) and the ratio of 1~(st)-2~(nd) , as well as one cardiac cycle time (1~(st)-2(_(HR)~(nd)). Results ①W1 in primary hypertension group increased compared with those of normal controls (P＜0.01), while no significant difference of W2, NA, R-1st, 1~(st)-2~(nd), R-1_(HR)~(st), 1~(st)-2_(nd)~(HR) was detected (P＞0.05). ②Both W1 and W2 correlated positively with pulse pressure (PP) and systolic blood pressure (SBP) (r=0.66, 0.55, P＜0.01;r=0.62, 0.44, P＜0.01). W1, W2 and age, DBP were not related significantly (P＞0.05). Conclusion The hemodynamic parameters of WI technology provide a new way to evaluate the dynamics of the heart and vascular system and their interaction.

Objective Glycodelin-A is one of glycoproteins secreted from endometrial epithelial cells , and it plays an im-portant role in embryo implantation , inhibition of reject reaction and pregnancy maintenance .Glycodelin-A will become an important potential marker in evaluating the endometrial receptivity and predicting the pregnancy outcome .The aim of this study was to investigate the correlation of glycodelin-A detected on the day of HCG and endometrial receptivity and the effects of glycodelin -A on the pregnancy outcome in the intrauterine insemination (IUI) period. Methods One hundred and seven woman patients with bilateral unobstruct-ed tubes and without endometrial lesions , endometrial polyps or intrauterine adhesions from Oct 2012 to Feb 2014 in our hospital were recruited in this study .Serum glycodelin-A in women receiving IUI on the day of HCG was measured by ELISA .Serum estradiol (E2), progesterone (P), and corpus luteum (LH) levels were measured by immunochemiluminometric assays .The condition of the endometrium was examined by transvaginalultrasonography . Results The serum glycodelin-A level on the day of HCG was higher in pregnant group [(1.47 ±0.38)ng/mL] than that in nonpregnant group ([0.62 ±0.13]ng/mL).The serum glycodelin-A level on the day of HCG was higher in endometrial thickness ≥7 mm group ([1.53 ±0.49]ng/mL) than endometrial thickness <7 mm group ([0.51 ±0.17]ng/mL). Conclusion The serum glycodelin-A level on the day of HCG may reflect endometrial receptivity to a cer-tain extent , which might have prognosis value for pregnancy following IUI .

Objective To investigate the eating problems of outpatient infants,preschool age children(1 to 7 years old) enrolled in the Department of Child Health Care,Nanjing Maternal and Child Health Hospital Affiliated to Nanjing Medical University,and to analyze its correlation with children's physical development,so as to establish strategies for preventing abnormal eating habit in children.Methods A toll of 2458 children met the criteria,and caregivers (mothers) completed the Children's Eating Behavior Questionnaires (CEBQ) in Department of Child Health Care,Nanjing Maternal and Child Health Hospital Affiliated to Nanjing Medical University were selected and the children's sociodemographic data and the morbidity of children eating problems were investigated.The correlation between children's body mass index(BMI) with children's eating problems was determined by using Chi-square test and multiple regression analysis.Results About 66.2％ (1627/2458 cases) had normal weight,and 10.8％ (257/2458 cases) and 8.5 ％ (210/2458 cases) were overweight (BMI ＞ P85-P95) or obese (BMI ≥ P95),respectively.The prevalence of eating behavior problems was detected during 25-36 months.For 1-to-7-year-old children,the highest detection rate of eating problems was inattention and eating at non-permanent locations,occupying 64.7％ (1590/2458 cases)and 50.5％ (1241/2458 cases),respectively;the prevalence rate of preferring to junk food was the lowest,accounting for 19.3％ (474/2458 cases).The children's eating problems had a high association with the children's BMI.Among them,children with eating problems,such as difficultly in accepting the varying food stuff[at the age of 12 month,odds ratio(OR)=11.50,95％ confidence interval(CI):1.84-72.16] and eating at non-permanent locations(at 25-36month,OR=1.77,95 ％ CI:1.11-2.83),were prone to be wasting away;children with eating problems,such as preferring to junk food (at 12 month,OR=5.08,95 ％ CI:1.43-18.00;13-18 month,OR=2.17,95 ％ CI:1.06-4.44),rarely eating vegetables or fruit (19-24 month,OR=4.06,95％CI:1.46-11.31) and inattention (12 month,OR=3.85,95 ％ CI:1.52-9.79),were associated with overweight or obesity (all P＜0.01).Conclusions There was a high prevalence of eating problems in children between 12-84 month(1-7 years old) in Nanjing.Improper children's eating behaviors can increase the risks of wasting away or children's overweight/obesity.

Objective: To investigate the influencing factors of depressive symptoms among rural elderly patients with chronic diseases in China, so as to provide insights into depression prevention and control among the rural elderly patients with chronic diseases. Methods: The basic demographics, health status, and lifestyle of rural residents at ages of 65 years and older who had at least one chronic disease were retrieved from The Chinese Longitudinal Healthy Longevity Survey (CLHLS) database in 2018, and participants' depressive symptoms were assessed with The Center for Epidemiological Studies Depression-10 (CES-D-10) scale. Factors affecting the depressive symptoms were identified with a multivariable logistic regression model. Results: Totally 5 146 rural elderly patients with chronic diseases were enrolled, including 2 373 men (46.11%) and 2 773 women (53.89%). The prevalence of depressive symptoms was 27.13%. Multivariable logistic regression analysis identified having two and more children (OR=0.614, 95%CI: 0.387-0.975), living alone (OR=1.450, 95%CI: 1.192-1.764), life satisfaction (general, OR=1.933, 95%CI: 1.651-2.264; low, OR=5.366, 95%CI: 3.488-8.254), self-assessed health status (general, OR=2.697, 95%CI: 2.284-3.185; poor, OR=5.338, 95%CI: 4.262-6.685), disability in instrumental activities of daily living (OR=1.592, 95%CI: 1.328-1.908), sleep duration (normal, OR=0.502, 95%CI: 0.429-0.586; too long, OR=0.494, 95%CI: 0.405-0.603), exercise (OR=0.721, 95%CI: 0.607-0.856), watching TV (OR=0.787, 95%CI: 0.664-0.933), and gardening activities (OR=0.781, 95%CI: 0.626-0.975) as factors affecting depressive symptoms among rural elderly patients with chronic diseases. Conclusions The prevalence of depressive symptoms was 27.13% among rural elderly patients with chronic diseases. Number of children, living style, life satisfaction, health status, sleep duration, exercise, watching TV, and gardening activities are associated with the development of depressive symptoms among rural elderly patients with chronic diseases.
