Objective To analyze the correlations between pediatric intersive cave unit (PICU) nurses′job satisfaction and their perception of job characteristics. Method One hundred and thirty-six PICU nurses from a women and children′s hospital of Guangzhou participated in the study and the job diagnostic survey (JDS) and Minnesota satisfaction questionnaire short-form (MSQ20) were used to investigate the relationship between the job characteristics and job satisfaction. Results The average score on general satisfaction was (3.57 ± 0.41). The dimensions like skill variety, task integrity, feedback from job and feedback from others, had a significant positive impact on general satisfaction (all P<0.05). Conclusion Nurses generally have a relatively middle level of job satisfaction and measures should be taken to improve their job satisfaction as well as the quality of nursing.

A 36-year-old female presented with multiple dark brown papules on the chest and abdomen for more than 10 years,which had gradually increased in number.Physical examination revealed dozens of dark brown,flat papules measuring 1-3 mm in diameter in the chest and abdomen.Most of the lesions had a smooth surface,and some lesions gave a papilloma-like appearance,with no confluent trend.Biopsy of abdominal lesions showed mild hyperkeratosis of epidermis,acanthosis,extension of epidermal protrusions forming a reticulated appearance,horn pseudocysts in prickle cell layer,enhanced pigmentation of basal layer,and a sparse lymphocytic perivascular infiltrate in superficial dermis.A diagnosis of dermatosis papulosa nigra (DPN) was made.

Objective: To explore the structural and functional changes of femoral and popliteal arteries in hypertension patients before and after drug therapy. Methods: A total of 201 hypertension patients treated in our hospital from 2010-03 to 2016-01 were studied. Based on blood pressure levels, the patients were divided into 3 groups: Grade-1 group,n=72, Grade-2 Group,n=68 and Grade-3 group,n=61. The patients were treated for 3 months and blood pressure was reduced below 140/90 mmHg. The intima-media thickness (IMT) of femoral and popliteal arteries was measured by two-dimensional ultrasound, blood vessel elasticity parameters of β, Ep, AC and PWV were determined by ET technology. The differences were compared between pre- and post-medication. Results: Compared with pre-medication, post-medication IMT in femoral artery was decreased in 3 groups, allP<0.05 and IMT in popliteal artery was similar,P>0.05; blood vessel elasticity parameters of β, Ep, PWV were decreased in 3 groups and AC was increased, allP<0.05. Conclusion: Drug therapy could effectively improve the elasticity of femoral and popliteal arteries in hypertension patients; two-dimensional ultrasound combining ET technology may dynamically monitor vascular elasticity of lower extremity which provides an objective basis for evaluating medication efifcacy in clinical practice.

Objective To investigate the relationship between rapists and related allele genes based on the analysis of 15 short tandem repeats (STRs) loci genetic polymorphism. Methods The method of Genome-wide scan was being used. Buccal swab samples of 129 rapists and 156 random populations were collected and PCR compound amplification was carried out with the aid of AmpFISTR Identifiler system. Then the products were subjected to electrophoresis and gene detection with AB13100 type gene analysis system so as to calculate and compare the alleles of 15 STRs gene frequency in the two groups. Results All the 15 STRs loci allele gene frequency in rapists and random population was found to coincide with Hardy-Weinberg law(P>0. 05). Allele 28 of D21S11 (rapists: 1.55% ,control group:5. 13%) ,allele22 of FGA(rapists:24.03% ,control group:16.99%),allele23 of FGA(rapists: 17.05% ,control group:26.28%) ,allele 10 of TH01(rapists:1.16% ,control group:4.17%) ,allele 8 of TPOX(rapists:55.77% ,control group:63.77%),allele 12 of TPOX(rapists:4.26% ,control group: 1.28%) were different between the two groups (P< 0.05) .while it is no differ significantly in other STRs loci allele gene(P >0.05). Conclusion Allele 28 of D21 S11,allele 22 and 23 of FGA, allele 10 of TH01, allele 8 and 12 of TPOX may be associated with the violent crime of rape. It is suggested that there are existing sensitive or resistance genes about the violent crime of rape in chromosome 2,4,11,21.

Objective To evaluate the clinical value of 6 h 99mTc-diethyl iminodiacetic acid (99mTc-EHIDA) planar hepatobiliary scintigraphy (HBS),6 h tomographic HBS and 24 h planar HBS in diagnosis on biliary atresia(BA).Methods Seventy cases(32 male,38 female) with continuous jaundice received planar and tomographic HBS in Beijing Friendship Hospital from Jan.2005 to Dec.2007.The mean age was 48.7 d (29 d-4 months).According to final diagnosis,all cases were divided into BA group (45 cases) and non-BA group (25 cases).All cases fasted at least 4 hours before HBS.The equipment was 3 head IRIX from Philips company with low energy high resolution collimator.The tracer was 99mTc-EHIDA and the radiochemistry purity was more than 95 percent.The dosage was 7.4 MBq/kg.All diagnosis demonstrated by operation pathology and clinical follow-up.All cases received HBS at 5,10,15,20,30 min and 1,6 h after tracer injection.HBS would ended if radioactivity appeared in gallbladder or intestine.These cases would received tomographic HBS and 24 h HBS if radioactivity did not appear in gallbladder or intestine at 6 h post injection.All these images were analyzed by 2 or more nuclear medicine physicians.Results There were not radioactivity appearing in gallbladder and intestine on planar and tomographic HBS of 27 cases,which suggested the BA.There were radioactivity appearing in gallbladder and intestine on planar and tomographic HBS of 30 cases,which suggested the non-BA.Positive rate of 6 h tomographic HBS was significantly higher than that of 6 h planar HBS and there was significantly difference between the 2 methods.Positive rate of 6 h tomographic HBS was significantly higher than that of 24 h planar HBS and there was significant difference between the 2 methods.Conclusions 99mTc-EHIDA HBS is a noninvasive,safety,valuable examing method and has definitely clinical value in the diagnosis on BA.The clinical value of 6 h tomographic HBS is significantly higher than that of 6 h planar HBS and 24 h planar HBS.

Selection and affinities of Cd binding peptides were assayed by phage random dodecapeptide library and affinity chromatography. Two Cd binding peptides were obtained, it was found that the affinities of Cu~ 2+ ,Co~ 2+ ,Zn~ 2+ ,Ni~ 2+ for Cd binding peptides were higher than that of Cd~ 2+ and Cr~ 2+ after detection of the amplified Cd binding peptides displayed phages to different heavy metal-charged resins; the detoxification of E.coli to Ni~ 2+ and Cd~ 2+ was enhanced when infected by Cd binding peptide displayed phages as compared with those of the control. The interaction of Cd binding peptide displayed phages with heavy metals charged resins was also observed under microscope. The work would be of great value and consequences for the study of interaction between heavy metals and proteins(peptides), as well as thedetoxification and bioremediation of heavy metals.

Objective To study the effect of injured podocytes on glomerular maturation and its underlying mechanism in neonatal mice.Methods Single i.p.injection with puromycin aminonucleoside (PA,0.1 mg/g BW) was given to ICR neonatal mice at day 1 after birth (1 dpp). Littermates injected with normal saline (NS) were used as control.Animals were examined for urine protein,blood pressure,kidney weight/body weight (KW/BW),renal histology at 2,4,8,12, 30,60 and 90 dpp (n=6～9 for each group).Immunohistochemistry and quantitative RT-PCR were performed to examine the expression of WT-1,CD31,VEGF,Flk-1,Ang-1,Ang-2,Tie-1 and Tie-2.Results Mice with PA injection had lower kidney weight and body weight at all time points as well as lower KW/BW at 4,8,12 dpp when compared with NS controls.Electron microscopy revealed nearly complete foot process effacement and segmental microvillous transformation as early as 1 day after PA injection.PA-injected kidneys showed fewer capillary loops and decreased maturation index as well as less CD31-positive endothelium in cortical glomeruli at 12 dpp. Glomerular mesangial injury and developing glomerulosclerosis along with proteinuria were noted in PA-injected kidneys starting from 30 dpp.Significantly increased systolic blood pressure was detected at 60 dpp in PA mice.Compared with NS injection,PA injection significantly induced decreased mRNA expression of Flk-1 and Tie-2 as well as increased expression of Ang-1,without obvious changes of VEGF at 2 dpp.Conclusions Podocytes in neonatal kidney of ICR mice are susceptible to PA. Such podocyte injury can alter the expression of VEGF and angiopoietin system in glomeruli,leading to abnormal development of glomerular capillaries,and subsequent proteinuria,hypertension and glomerulosclerosis.

Objective To investigate the clinical efficiency of applying tibial artery perforator flap to treat anterior medial incision poor healing one-stage after Pilon fracture.Methods From June,2012 to August,2015,13 cases of anterior medial incision poor healing after Pilon fracture,with tendon or plate exposure in patients and without acute infection,treated by tibial artery perforator flap to repair wound one-stage after thorough debridement.Results All the wounds were repaired by tibial artery perforator flap after a thorough debridement.There was flap necrosis in distal 1/3 part of flap in 1 case,which gained healing after debridement and skingrafting.The remaining 12 cases of flaps survived well.All patients were followed up for 5-14 months (mean 9.8 months),the flaps or skin grafts survived well,without tissue infection,osteomyelitis and other complication,and the functional recovery of the ankle was basically normal.Conclusion It is a simple and effective method by using posterior tibial artery perforator flap to treat anterior medial incision poor healing one-stage with non-acute infection after Pilon fracture on the basis of thorough debridement,worthy of clinical application and promotion.

OBJECTIVETo compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.

RESULTSThuVEP, in comparison with HoLEP, achieved a significantly shorter operation time ([57.6 +/- 12. 8] vs. [70.4 +/- 21.8] min, P = 0.001) and a higher laser efficiency ([0.71 +/- 0.18] vs. [0.62 +/- 0.19] g/min, P = 0. 021). At 1, 6, or 12 months of follow-up, no significant differences were observed in IPSS, OOL, Omax, and PVR between the two groups (P > 0.05). Both the HoLEP and ThuVEP groups showed low incidences of complications and remarkably improved IIEF-EF scores at 12 months postoperatively, but with no significant differences (both P > 0.05). However, in those with relatively normal erectile functions before operation, the mean IIEF-EF score was reduced from 22.8 +/- 2.2 preoperatively to 21.0 +/- 2.7 after HoLEP, (P = 0.036).

CONCLUSIONBoth HoLEP and 120W ThuVEP are effective and safe in the treatment of BPH. Compared with HoLEP, 120 W ThuVEP has even a higher laser efficiency. However, neither can significantly improve erectile function, and HoLEP may have a short-term negative impact on the relatively normal erectile function of the patient.
