Purpose To detect the expression of insulin-like growth factor-ⅡmRNA-binding protein 3 (IMP3) in preeclampsia (PE) placentas. Methods The levels of IMP3 expression were measured using immunohistochemistry in 8 cases of mild PE, 41 cases of se-vere PE, 6 cases of fetal growth restrict ( FGR) without PE and 22 cases of normal late trimester of pregnancy placentas. Results Compared with normal late trimester of pregnancy, the expression of IMP3 was obviously decreased in severe PE placenta ( Z =-2. 063,P<0. 05), decreased in mild PE (Z= -1. 31,P>0. 05). The expression of IMP3 in severe PE placenta was lower than that of mild PE placenta but not statistically significant (Z= -0. 233,P>0. 05). The expression of IMP3 in early onset PE placenta was lower than that of late onset PE placenta but not statistically significant(Z= -0. 108,P>0. 05). Compared with normal late tri-mester of pregnancy, the expression of IMP3 was significantly decreased in PE with FGR placenta (Z= -2. 375,P <0. 05), de-creased in FGR without PE and PE without FGR (Z= -1. 225,P>0. 05, Z= -1. 36,P>0. 05). Conclusion The results indicate that IMP3 protein expression is low in sever PE, which may be one of the pathogenesis of PE. IMP3 may be used as a marker to predict PE with FGR, and to provide a basis for the development of a novel therapeutic target in PE.

Objective To investigate the impact of applying patient-centered care concept on easing the negative moods among the parents of the neonates hospitalized in NICU.Methods The parents of neonates (76 people) hospitalized in NICU from March to May in 2012 were selected as the control group,they conducted normal nursing.The parents of neonates hospitalized in NICU during June and August in 2012 were named as the observation group (81 people).In addition to the normal nursing,they were given nursing intervention according to patient-centered care concept.The anxiety and depression moods of the two groups was analyzed.Results Before the patient-centered care concept intervention,there was no statistical difference of SAS,SDS scores for both groups.For the observation group,the SAS,SDS scores after intervention were significantly lower than those before the intervention.While for the control group,there was no statistical difference of SAS,SDS scores.After intervention,the SAS、SDS scores of the observation group were significantly lower than those of the control group,and the difference was statistically significant.Conclusions The negative moods of the parents of hospitalized neonates can be eased significantly by applying patient-centered care concept intervention.

Objective To investigate the changes of blood coagulation indices during the percutaneous cor-onary intervention(PCI), so as to provide evidence for anticoagulation therapy. Methods 34 acute coronary syn-drome patients were enrolled,whose blood sample was taken at baseline,1 h,4 h,24 h,and 48 h after PCI operation. Thrombin-antithrombin complex(TAT), vWF, protein C, antithrombin, fibrinogen, D-dimer were tested. The result was processed by statistical software. Results After PCI, TAT continued to rise, protein C and antithrombin drop down,the vWF and D-dimer rose with TAT,and fibrinogen transiently drop down. Conclusion The thrombin pro-duces more quickly after PCI,its time phrase is coordinated with vWF and D-dimer,at the same time the anticoagula-tion system drops down. High anticoagulation at least maintains within 48 h and then tends to be normal.

Background Pseudoexfoliation syndrome (PEX) has a high incidence in Uygur population and usually leads to secondary glaucoma and complicated cataract.The abnormal change of lens tissue and degeneration of zonular fibers bring a lot of difficulties for phacoemulsification (phaco) with intraocular lens implantation,especially stop-and-chop phaco technique.Prechop technique is a new choping technology,but its application in PEX with cataract is less.Objective This study was to compare the efficacy and safety of pre chop phaco technique and stop-and-chop phaco technique for PEX combined cataract.Methods A randomized controlled Clinical trial was designed.Forty-one eyes of 41 patients with PEX combined cataract of Ⅲ degree of nucleus were enrolled in People's Hospital of Hetian District from March 2015 to January 2016.The patients were randomized into the prechop group and stop-and-chop group according to random nubmer table,and cystotome-assisted prechop phaco surgery and stop-and-chop phaco surgery were performed in different groups,respectively.The effective phaco duration,corneal endothelium loss rate,cornea edema eye number after operation,vision outcomes and complications were compared between the two groups.Results The mean effective phaco duration was 14.0 (13.0,16.5) minutes and 18.5 (16.5,24.0) minutes in the prechop group and stop-and-chop group,with a significant difference between them (Z =17.354,P ＜ 0.01).The corneal endothelial cells were (2 101.90 ± 209.08)/mm in the prechop group,and the number was similar to (2 002.30 ± 207.04)/mm of the stop-and-chop group (t =-1.530,P =0.134).Corneal endothelial cell lossing rate was (8.27±2.23)％ in the prechop group,which was lower than (13.09±4.26)％ in the stop-and-chop group (t =3.810,P =0.001).The BCVA was better in the prechop group than that in the stop-and-chop group in postoperative day 3 (P =0.044),and the corneal edema degree was not signigicantly different in postoperative day 1 and day 3 between the two groups (P=0.221,0.446).Intraoperative complication was rapture of zonule and occurred in 1 eye and 2 eyes in the prechop group and stop-and-chop group,respectively.Conclusions Compared with the stop-and-chop phaco technique,the prechop phaco tequnique can decrease intraoperative complication,lighten the postoperative damage of corneal endothelial cells and accelerate visual rehabilitation in PEX combined with cataract patients.

Objective To investigate the effect of Kangaroo care(KC)on diminishing neonatal pain during heel lancing. Methods Sixty neonates were divided randomly into two equal groups:intervention group and control group,which 30 cases in each group.In the intervention group,neonates were treated with KC(neonates were put in direct and continuous skin-to-skin contact with his/her mom)from 20 mins before heel lancing to 1 mins after the end of the lancing.In the control group,neonates were treated with regular care.The differences in heart rate,blood oxygen saturation,facial pain expression,crying duration and DAN(Douleur Aigue Nouveaune)scores between two groups were compared at 7 time points from 10s before the heel lancing to 10s after the lancing. Results The results of repeated measu te at 7 time points after heel lancing.There were significant interaction effect between time and main effect(P<0.01),which showed that the heart rate of two groups were not equal at different time points.Compared with the time effects(P<0.01)which showed that two groups of neonatal heart rate of the two groups would accelerate with time extension. There were significant differences(all P<0.05)in heart rate at 7 time points between two groups and smaller heart rate varied range in intervention group.The results of repeated measures analysis for neonatal blood oxygen saturation at 7 time points after heel lancing. There were significant interaction effect between time and main effects(P<0.01),which showed that the blood oxygen saturation of two groups were not equal at different time points.Compared with the time effect(P<0.01),which showed that two groups of neonatal blood oxygen saturation would reduce with time extension.There were significant differences(all P<0.05)in blood oxygen saturation of two groups at 30s,40s and 50s after heel lancing and smaller blood oxygen saturation varied range in intervention group.The crying duration and DAN scores in intervention group were significantly reduced compared with the controls(all P<0.05).Conclusions
Heel lancing could lead to moderate to severe pain of neonates.KC could effectively diminish the neonatal pain degree caused by heel lancing.

Objective To investigate the process of apoptosis in lungs and liver induced by crushing hindlimbs of rat, and study the mechanismof crush injury. Methods The rat experimental model of hindlimbs crush injury was established. The cell apoptosis in lungs and liver was detected by TUNEL assay, and the expression of Bax, Bcl-2 and caspase-3 apoptin was examined by immunohistochemistry. Results C ompared with the control group, the partial muscle injury of rat’s hindlimbs was more serious with more apoptosis observed in lungs and liver (P<0.05). The expression of Bax was up-regulated and Bcl-2 was down-regulated, whereas caspase-3 expression was activated (P<0.05). Conclusion The cell apoptosis has increased significantly in lungs and liver after crush injury of hindlimbs in rat. The corre-lation factor released during tissue injury may mediate apoptosis process.

Objective To analysis the diagnostic values and characteristics of ultrasound and ultrasound guided fine needle aspiration cytology (FNAC) in patients with papillary thyroid carcinoma (PTC) before operation. Methods The data of ultrasound and ultrasound guided FNAC in 129 patients (including 148 PTC nodules) with PTC were collected from January 2014 to February 2017, and the diagnostic reports and feature descriptions of ultrasound and ultrasound guided FNAC were analyzed retrospectively. Results Among the 148 PTC nodules, the ultrasonographic imaging showed that 84.5% (125/148) with low echo-level solid nodules, 61.5% (91/148) with echo heterogenicity, 77.7% (115/148) with a ratio ≥ 1 in longitudinal/breadth, 69.6 % (103/148) with fuzzy boundary, 75.0% (111/148) with microcalcification in nodules, 97.3% (144/148) without or with incomplete aureole, 64.9% (96/148) with rich blood flow and 7.0% (9/129) with enlargement of cervical lymph nodes. The FNAC diagnosis showed that 78.4% (116/148) was diagnosed with suspected papillary carcinoma, 1.4% (2/148) was diagnosed with malignent tumor, 11.5% (17/148) was diagnosed with atypia of undetermined significance (AUS), 1.4% (2/148) was diagnosed with benign lesion, 0.7% (1/148) was diagnosed with follicular neoplasm and 6.7% (10/148) could not be diagnosed. If the suspected papillary carcinoma and malignent tumor were defined as cytodiagnosis, the diagnostic accordance rate with intraoperative pathology was 79.7%. Conclusion The preoperative accuracy rates of ultrasound diagnosis and ultrasound guided FNAC diagnosis for patients with PTC are high, and the characteristics of the both are also typical. The two examinations before operation are helpful for early diagnosis and treatment formulation for patients with PTC.

Objective: To investigate the inhibitory effects on m yeloperoxidase (MP O) oxidation activity by affinity-purified anti-MPO antibodies from patients w it h microscopic polyangiitis (MPA) and to further investigate the interaction betw een MPO, ceruloplasmin and anti-MPO antibodies. Methods: Human IgG fractions wer e purified from plasma of 11 patients with anti-MPO antibody positive MPA and s e ra of 12 normal controls. Anti-MPO antibodies were further purified from anti- MP O antibody containing IgG fractions using MPO affinity chromatography. The enzym e activity of MPO was measured, in the presence of anti-MPO antibodies and norm a l IgG preparations, using a classical MPO oxidation assay. Interaction between c eruloplasmin, MPO and anti-MPO antibodies was further investigated using ELISA. Results: Anti-MPO antibodies from 7/11 patients with MPA could inhibit the MPO a ctivity as non-competitive inhibitors in a dose-dependent manner. Ceruloplasmi n could competitively inhibit the oxidation activity of MPO in a dose-dependent an d time-dependent manner. Anti-MPO antibodies could inhibit the binding between M PO and ceruloplasmin to a maximum of (75.4?11.6)%. Conclusion: Anti-MPO antibod ies, from the majority of patients with MPA, could inhibit the oxidation activity of MPO and interfere with the binding between MPO and ceruloplasmin.
