Kallikrein-kinin system consists of kininogen , kallikrein, bradykinin and kinin .Kinins, derived from kininogen by tissue kallikrein , play their biological effects via bradykinin 1/2 receptors or protease activated receptors .Existing researches suggest that kinins exert various effects through different intracellular and mitochondrial signal pathways such as MAPK , PI3K/Akt/GSK3 be-ta, NO, JAKs/STATs.This review aims to elucidate the roles and the intracellular signal pathways of KKS in different diseases .

Objective To study the relationship between MRI features and pathological characteristics of the renal clear cell carcinoma,and to conduct a comparative analysis.Methods 23 patients renal clear cell carcinoma who were proved by postoperative pathology were retrospectively analyzed. The preoperative MRI findings and the postoperative pathological characteristics were compared. Results MRI plain scan showed uniform signal was seen in 2 cases, and mixed signal was found in 21 cases with cystic and necrosis. Blood was seen in 11 cases and false envelope was present in 12 cases. Dynamic enhanced scanning revealed that solid part was enhanced obviously, it was lower than the renal cortex but higher than the renal medulla in cortical phase and continued to be enhanced in medullary phase and delay phase.Postoperative pathological characteristics showed that tumor profiles were yellow-white and cystic and necrotic structures were present within tumors, blood was found in 17 cases. Endoscopic tumor cells were present in solid nests or acinar structure, and mesenchyma was rich in thin-walled vessels involved in reticular interval.14 cases were found to have false envelope.Conclusion Renal clear carcinoma MRI imaging manifestion is related to organixational srructure. MR plain scan combined with dynamic enhanced scan has very high value in the diangnodis of renal cell carcoinoma.

Objective To investigate the expressions and mutual relationship of Galectin-3 andβ-catenin in endome?triosis (EM). Methods Immunohistochemistry was used to detect expression levels of Galectin-3 andβ-catenin and their mutual relationship in expression was also examined. Samples were collected from ectopic endometrium of patients with en?dometriosis (ectopic endometrium group, n=34), eutopic endometrium of patients with endometriosis (eutopic endometrium group, n=34) and normal endometrium from people without endometriosis (control group, n=30). Results The expressions of Galectin-3 were seen in 88.2%, 85.3%, 50.0%of cases in ectopic endometrium group, eutopic endometrium group and control group respectively. On the other hand, the expression ofβ-catenin were seen in 55.9%, 52.9%, 26.7%of cases in ecto?pic endometrium group, eutopic endometrium group and control group respectively. In EMs patients, the expression of Galec?tin-3 andβ-catenin were significantly higher in ectopic endometrium and eutopic endometrium than those in normal endome?trium group(P<0.05). Expression of Galectin-3 was positive correlated with expression ofβ-catenin(rs=0.512, 0.428, P<0.01). Conclusion Galectin-3 andβ-catenin may play important roles synergistically in the pathogenesis of endometriosis.

Serum triglyceride ( TG ) , total cholesterol ( TC ) , low density lipoprotein cholesterol ( LDL-C) , high density lipoprotein cholesterol ( HDL-C) , uric acid ( UA) levels and fasting blood glucose ( FBG) were measured in 67 patients with chronic spontaneous urticaria ( CSU ) and 66 healthy subjects ( controls).Results showed that the rates of increased serum TG and FBG levels in CSU patients were higher than those in controls ( 19% vs.6%,χ2 =5.309, P <0.05; 12% vs.1%,χ2 =4.194, P <0.05, respectively);however, there were no significant differences in abnormal rate of TC(7%vs.3%) , LDL-C (4%vs.1%), HDL-C(6%vs.3%)and UA(6%vs.1%) between CSU patients and healthy controls(all P>0.05).The rate of rising FBG in CSU patients accompanied by angioedema(4/9)was higher than that in CSU patients without angioedema(7%,χ2 =7.181,P<0.05).

The clinical data of 7 patients with porokeratosis (PK) were analyzed retrospectively.In 7 PK patients, 4 cases were disseminated superficial actinic porokeratosis (DSAP),1 case was disseminated superficial porokeratosis (DSP),1 case was giant porokeratosis (GP) and 1 case was hypertrophic porokeratosis (HP).The characteristic cutaneous manifestations were annular well-circumscribed keratotic plaques with slightly atrophic center and elevated border.All patients shared a common histological hallmark, the cornoid lamella.Four cases of DSAP patients had family medical history, consistent with autosomal dominant inheritance.DSP, GP and HP patients denied family medical history.Diagnosis of PK should be based on clinical manifestations, family medical history and histopathological examination.

Objective Hypertension is a leading modifiable risk factor for cardiovascular disease .However , a lot of hyper-tension patients hold inactive attitudes to hypertension treatment .The purpose of this study was to investigate the relationship between previous treatment of hypertension and stroke severity in acute ischemic stroke . Methods We retrospectively analyzed the clinical data of 653 in-hospital ischemic stroke patients with hypertension between January 2011 and December 2014 .According to the National Institutes of Health Stroke Scale (NIHSS) at admission, the stroke patients were divided into a mild group (NIHSS≤3) and a severe group (NIHSS >3) and, based on their history of hypertension treatment , allocated to a regular treatment, an irregular treatment, a non-treatment , and an unawareness group .We studied the relationship of previous hypertension treatment with stroke severity by Spearman correlation analysis and identified the potential factors associated with stroke severity by multivariate logistic regression anal-ysis. Results Previous treatment of hypertension was positively correlated with stroke severity (r=0.146, P=0.000 2).Compared with the patients of the regular treatment group , those in the irregular treatment group (OR: 2.21; 95%CI:1.39 -3.52; P =0.001), non-treatment group ( OR: 2.18; 95%CI: 1.41 -3.36; P =0.0004) and unawareness group (OR:1.80;95%CI:1.12-2.88; P=0.015) tended to have more severe stroke. Conclusion Previous treatment of hypertension is closely related to the severity of ischemic stroke .

Objective It remains to be confirmed whether tissue kallikrein has neuroprotective effect in diabetes-induced stroke.This study was to investigate the neuroprotection of tissue kallikrein against cerebral ischemia-reperfusion injury in diabetic rats. Methods Healthy male SD rats were randomly divided into a sham operation, a saline control, and a tissue kallikrein group.Diabetes mellitus was induced in the animals by intraperitoneal injection of streptozotocin and the model of focal cerebral ischemia-reperfusion was made with an intraluminal vascular occlusion method. At 24 hours after modeling, we obtained the neurological deficit score, in-farct size, and brain water content, counted Iba1-and MPO-positive cells by immunohistochemistry, and determined the expressions of ICAM-1 and VCAM-1 by real-time PCR. Results In comparison with the saline controls, the rats treated with tissue kallirein showed significant decreases in the neurological deficit score (P<0.01), the infarct size ([23.57 ±5.79] vs [47.97 ±1.19]%, P<0.01), brain edema ([81.73 ±2.10] vs [84.94 ±2.34]%, P<0.05), the counts of Iba1-and MPO-positive cells (12.33 ±4.46 vs 31.83 ±8.13 and 13.83 ±4.49 vs 37.50 ±7.64, both P<0.01), and the expressions of ICAM-1 and VCAM-1 (both P<0.05). Conclusion Tissue kallikrein has a neuroprotective effect against cerebral ischemia-reperfusion injury in diabetic rats, which may be associated with its anti-inflammation property.

Objective To investigate long-term data of dry eye after LASIK in young myopia patients.Methods Young myopia patients were divided into treated group (group A) and control (group B),who were interviewed before surgery and on 1 year,3 years and 5 years after surgery.Their diopters,uncorrected visual acuity (UCVA),tear breakup time test,Schirmer I test and corneal fluorescent staining were taken,then dry eye was diagnosed and OSDI questionnaire were scored.Results The postoperative incidence of dry eye in group A was higher than that before surgery (35.6％) and decreased with time (51.7％,44.9％ and 40.7％,respectively),and there was no significant difference in group B at each time point (P ＞ 0.05).The preoperative incidence of dry eye was equal between two groups (P ＞ 0.05),which were much higher in group A after surgery (all P ＜ 0.05).In group A,the postoperative constituent ratio of mild dry eye was the majority and decreased with time (65.6％,52.8％,41.7％,respectively),while moderate and severe dry eye was increased,especially the latter (6.6％,11.3％ and 16.7％,respectively;P ＜ 0.05).At 5 years after surgery,the UCVA and visual function score in dry eye patients were lower than those of non-dry eye patients (all P ＜ 0.05),while the residual refraction and ocular symptom score were higher than those of dry eye patients (all P ＜ 0.05).Conclusion Dry eye disease may last for a long time and may getting worse after LASIK.Therefore,we should pay more attention to the development of dry eye long after LASIK in young myopic patients.

Objective Inflammation response is involved in the whole pathological process of acute cerebral infarction ( ACI) , but few reports are seen on its clinical implication in ACI patients .The purpose of this study was to investigate the predictive value of the differential count of leukocytes for stroke severity and early clinical outcomes in the acute phase of cerebral infarction . Methods We collected the clinical and laboratory data of 635 patients diagnosed with ACI within 72 hours of symptom onset and eval-uated the association between the differential count of peripheral blood leukocytes and stroke severity at admission and within 3 days af-ter admission as well as the clinical outcomes at discharge .The neural function impairment scores of the patients were obtained with The NIH Stroke Score ( NIHSS) at admission and on the third day after admission , and the therapeutic results evaluated with the modi-fied Rankin Scale ( mRS) , mRS >2 as poor prognosis .Analyses were performed on the correlation of the differential count of leuko-cytes with NIHSS and mRS scores and its influence on the ACI patients . Results At discharge , the mRS related influencing factors included the total count of leukocytes (OR=1.147, 95% CI:1.038-1.268), count of neutrophil cells (OR=1.227, 95% CI:1.00-1.369 ), count of lymphocytes ( OR =0.508, 95% CI:0.342-0.753), and neutrophil to lymphocyte ratio (NLR) (OR=1.150, 95%CI:1.008-1.314).the NIHSSs were correlated with the counts of leucocytes (r=0.078, P=0.024), neutrophil cells (r=0.083, P=0.019), and lymphocytes (r=0.010, P=0.004) at admission, and with the counts of leucocytes ( r =0.238, P <0.001), neutrophil cells (r=0.335, P<0.001), lymphocytes (r=-0.269, P<0.001), and NLR (r=0.423, P<0.001) on the third day after admission. Conclusion In the acute phase of cer-ebral infarction , the differential count of leukocytes and NLR are valuable for predicting the severity of neurologic impairment and early poor functional outcome .
