Objective To investigate the relativity between morning blood pressure surge (MBPS) and carotid atheresclerosis. Methods Noninvasive ambulatory blood pressure monitor (ABPM) was per-formed on 97 patients with the first and second stage of essential hypertension and according the ABPM re-suits, the patients were classified into MP+ group (31 cases) and MP-group (66 cases). In the meantime, the carotid intima-media thickness (IMT) and the carotid atheresclerotic plaque was examined by the color Doppler ultrasound. The relationship among MBPS, carotid atherosclerotic plaque and IMT was analyzed.Results The IMT of common carotid artery (CCA), carotid artery bifurcation (CAB)and internal carotid artery (ICA) in MP+ group was significantly higher than that in MP- group [ (1.02±0.36)mm vs (0.86±0.22) mm, (1.14±0.39 ) mm vs(0.96±0.26) mm, (0.94±0.30 )mm vs ( 0.82±0.18 mm ), P<0.05 ]. The ratio of carotid atherosclerotie plaque in MP+ group was significantly higher than that in MP- group (64.5% vs 42.4%,P<0.05). Conclusions The MBPS is related to carotid atheroselerotie plaque and the carotid IMT. The MBPS may accelerate the forming and developing of atherosclerosis.

Objective To study the changes of diamine oxidase (DAO )and intestinal fatty acid binding protein (I-FABP)levels in neonates with hypoxic-ischemic encephalopathy treated with selective brain hypothermia.Methods Collect a sample of 60newborns with moderate and severe hypoxic-ischemic encephalopathy who were hospitalized in the NICU of Matemal and Child Health Care Hospital of Baoding from June 2013to December 2014.The 60newborns were divided into two groups randomly:hypothermia group(n=30)and conventional treatment group(n=30).Selected 30cases hospitalized at the same period, except the related to the ischemia hypoxia and gastrointestinal dysfunction disease as the control group.The levels of serum levels of DAO and I-FABP were measured by ELISA on admission and 7days after treat-ment,respectively.And the score of gastrointestinal dysfunction were compared.Results Neither the levels of DAO and I-FABP in hypothermia group and conventional treatment group had statistical differences on ad-mission[DAO:(15.77±2.04)U/ml,(15.81±1.85)U/ml,P﹥0.05;I-FABP:(310.01±46.43)ng/L, (301.12±38.61)ng/L,P﹥0.05],but were higher than that in the control group [(7.65±0.74)U/ml, (51.65±6.91)ng/L].Seven days after treatment,both the levels of DAO and I-FABP of hypothermia group and conventional treatment group decreased [DAO:(7.88±1.87)U/ml,(12.51±1.53)U/ml;I-FABP:(59.16±6.17)ng/L,(121.31±21.54)ng/L],meanwhile,the variation of hypothermia group was more significant(P﹤0.05).The correlation of the plasma DAO and I-FABP levels and the score of gas-trointestinal dysfunction was significantly (r1=0.831,r2=0.827,P ﹤0.01).Conclusion Hypothermia treatment could effectively reduce the levels of DAO and I-FABP,thus improve the gastrointestinal function in some extent.

Objective To explore the clinical features and treatment strategy of severe anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis in children. Methods The clinical data and follow-up information of 4 children with severe anti-NMDAR encephalitis were retrospectively analyzed. Results Four patients (one male and 3 females) were 10 to 13 years old and one child had teratoma combined. In all patients symptoms at onset mainly were psychiatric syndrome and movement disorder, and then progressed to seizures, disturbance of consciousness and central hypoventilation respiratory failure in one month. The anti-NMDAR antibodies in cerebrospinal fluid were positive in all patients. The EEG showed focal or diffuse slow waves. The brain MRI showed no pathological changes at the diagnosis. The treatment included methylprednisolone and large doses of intravenous immunoglobulin (IVIG), ventilator for 5-95 days, and tracheotomy in 2 cases. One case died because of serious infection. In 21-27 months of the follow-up, one case had clinical recovery; 2 cases had the sustained use of immunosuppressive agents and anti-epileptic drugs and the clinical symptoms were significantly improved. The EEG and anti-NMDAR antibodies continued abnormal in the patient combined with teratoma. One patient relapsed. Conclusions The severe anti-NMDAR is more likely in older female children. The central hypoventilation respiratory failure occurs in the early course of the disease. Combination with tumor is high risk factor. Conventional hormone therapy and ventilator treatment is effective. The recovery is slow. It may be relapsed even one year later.

Objective To evaluate the relationship of clinical symptom to plasmic levels of D-dimer, activated factorⅦ (FⅦa) and tissue factor pathway inhibitor (TFPI)/X a in patients with urticaria. Methods A total of 27 patients with chronic urticaria (CU), 27 patients with acute urticaria (AU) and 26 normal human controls were included in this study. Symptom score was determined and disease course was surveyed in these patients. ELISA was used to detect the plasma levels of D-dimer, FⅦa and (TFPI)/Xa in patients and controls. The relation of clinical symptom and disease course to plasma levels of these parameters was assessed. Results In patients with AU and normal controls, the plasma level of D-dimer was 450.57± 242.13 ng/mL and 266.81±40.68 ng/mL, respectively, the level of FⅦa, 2.23± 0.74 ng/mL and 5.23±1.35 ng/mL, respectively, and the level of TFPI/Xa 0.87±0.13 nmol/L and 0.88 ~ 0.12 nmol/L, respectively. There was a significant difference in the level of both D-dimer and FⅦa (both P < 0.01 ), whereas no differ-ence was observed in that of TFPI/X a (P > 0.05) between patients with AU and normal controls. In addi-tion, increased level of D-dimer and decreased level of FⅦa were noticed in patients with CU compared with those in normal controls (593.80±294.04 ng/mL vs 266.81±40.68 ng/mL, 3.98±0.35 ng/mL vs 5.23± 1.35 ng/mL, both P < 0.01 ), but there was no significant difference in the plasma level of TFPI/Xa (0.87± 0.16 nmol/L vs 0.88±0.12 nmol/L, P > 0.05). Significant difference was observed in the plasma level of D-dimer and FⅦa between patients with AU and CU (450.57±242.13 ng/mL vs 593.80 ±294.04 ng/mL, P < 0.05; 2.23± 0.74 ng/mL vs 3.98± 0.35 ng/mL, P<0.01 ). The plasma level of D-dimer positively corre-lated to the symptom score of patients with CU and those with AU (r= 0.68, P< 0.01; r= 0.82, P< 0.01),but was independent of discase course (P> 0.05). Neither the level of FⅦa nor that of TFPI/Xa correlated to symptom score or disease course of patients (all P > 0.05). Conclusions There is an overactivation of coagulation cascade, consumption of blood coagulation factors and secondary fibrinolysis in patients with urticaria, suggesting that plasma D-dimer and FⅦa may be associated with the clinical symptoms of urticaria.

Objective To study the value of SCCAg,CYFRA21-1 and TPS in the diagnosis and prognostic evaluation of patients with cell cervical cancer (SCC).Methods The levels of serum SCCAg,CYFRA21-1and TPS from 160 SCC patients and 60 health women were detected by means of ELISA.Results ( 1 ) The levels of serum SCCAg,CYFRA21-1and TPS in SCC were significantly higher than those of normal group ( P ＜0.001 ).The median values of normal group:0.43 μg/L,0.43 μg/L,26 U/L,the median values of cervical cancer group:1.96 μg/L,2.29 μg/L,149.1 U/L ( 2 ) The specificity of SCCAg,CYFRA21-1 and TPS in diagnosing SCC were both 100％.The sensitivity of SCCAg,CYFRA21-1 and TPS in diagnosing SCC was 53.42％,40.68％ and 83.95％,respectively.The sensitivity of TPS was obviously different from SCCAg and CYFRA21-1 ( P ＜0.001 ).The sensitivity of SCCAg plus CYFRA21-1 and three markers together were 69.23％and 92.31％,respectively.(3)The expressing of SCCAg,CYFRA21 -1 and TPS in FIGO stages Ⅲ plus Ⅳ was significantly higher than in stages Ⅰ plus Ⅱ (P ＜ 0.05 ),and all markers were not related to the degree of histological differentiation.SCCAg was correlated strongly with tumor size,growth type,lymph node metastasis and age( P ＜ 0.05 ),but CYFRA21-1 was not correlated with all these factors.TPS level was significantly associated with tumor size and lymph node metastasis( P ＜0.05 ),but not with growth type and age.(4)A total of 78 patients were followed up.The pretreatmental serum levels of SCCAg and CYFRA21-1 in patients with recurrence were significantly higher than those without recurrence( P ＜0.05 ).The same trend was not found for TPS.Compared with the normal control,the patients with elevated SCCAg before treatment has shorter intervals before recurrence and metastasis occurred.Also,the survival of patients with elevated SCCAg before treatment was shorter than the normal control ( P ＜ 0.05 ).Conclusion SCCAg,CYFRA21-1 and TPS serum levels are valuable markers for the diagnosis of SCC.Meanwhile,SCCAg and CYFRA21-1 are chnically significant pridictors for the prognosis of SCC.

Objective To investigate the indications and results of long channel technique with pedicle inner preputial flap urethroplasty for middle hypospadias repair. Methods During September 2007 to April 2010,28 cases of middle hypospadias were include in this study.The average age was 2.0 years (1.5 -6.0 years).The orifice of urethra was opened in the shaft of penis,and the distance between the urethral meatus and the center of glans was 25 mm ( 16 - 37 mm).A pars-meatus skin incision was made,which was dissected deep to the urethral plate.The urethral plate was transected,and a long channel between the urethral plate and the corpora cavernosa was created.The neourethra was made from the inner prepuce,and transposed to the ventral tunnel through a tunnel between buck's fascia and albuginea of ventrolateral corpora cavernosa.The neourethra was anastomosed with the proximal urethra.The buck's and dartos fascia along the skin incision were brought together and sutured individually,covering the proximal neo-urethra and the anastomosis.Induced penile erection confirmed that 13 cases were with mild penile curvature,and the other 15 case were without penile curvature.The average length of the defected urethra and tunnel was 38 mm (30 -42 mm) and 33 mm (26 -38 mm). ResultsSuccess was achieved in all cases without fistula or urethral stricture formation with the average follow-up of 20 months (6 -31 months),and penile curvature was completely corrected.The urethra was opened in the apex of the glans with normal-looking circumcised penis. ConclusionsLong channel technique with pedicle inner preputial flap urethroplasty can provide another option for repairing middle hypospadias without penile curvature or with mild penile curvature,especially for young children and those with small penis.This technique is simple,and the result is satisfied.

Objective To explore the efficacy of cold packs combined with ice compress in treatment of pain after erbium fractional photothermal therapy on acne scars. Methods Eighty cases which were confirmed to the criteria were randomized into two groups:treatment group and control group. The treatment group (n=40) treated with cold packs combined with cold icy compress immediately after the surgery for 30~40 mins. The control group (n=40) was given icy compress therapy immediately after the surgery for 30~40 mins. The therapy continued for three days after the surgery on the two groups. The self-feeling symptom and pain relieving time were compared between the two groups. Result The time for pain relief in the wounds and the time for scabbing were both significantly shorter than those in the control group (P<0.01). Conclusion The cold packs combined with ice compress therapy can relieve the pains effectively and it can shorten the recovery time after fractional photothermal therapy.

Objective To study the changes of diamine oxidase (DAO)levels in neonates with hypoxic -is-chemic encephalopathy (HIE)treated with selective brain hypothermi,also to further evaluate Scores for Newborn Gastrointestinal Functior (SNGF).Methods 60 newborns with moderate and severe HIE who were in the NICU of our department from June 2013 to December 2014 were collected.The 60 newborns were randomly divided into hypo-thermia treatment group (HG)and conventional treatment group(CG).The serum was collected and ELISA method was used to test the consistency of DAO on admission and 7 days afterwards,respectively.Meanwhile,the SNGF level of the two groups at the two time points was compared.Results Neither the DAO and SNGF level of the two groups had statistical difference on admission(all P >0.05).Seven days later,both the DAO of the two groups and the SNGF decreased[(12.51 ±1.53)u/mL vs (7.88 ±1.87)u/mL,however,the variation of the hypothermia treatment group was apparently more significant than the change of the conventional treatment group(P =0.011).The SNGF scores of the two groups all decreased,while the hypothermia treatment group was significantly lower than the conventional treat-ment group,the difference were statistically significant (P =0.044,0.006,0.013).Besides,there was remarkably positive correlation between serum DAO level and SNGF (r1 =-0.825,r2 =-0.876,all P <0.05).Conclusion Hypothermia treatment could effectively reduce the injury of asphyxia neonatal gastrointestinal tract by inhibiting the level of DAO,thus improve the gastrointestinal function.

ObjectiveTo explore the importance and significance of classification diagnosis and treatment of chordee among hypospadias in children.MethodsA random sample review and controlled study was made in patients with hypospadias and chordee from 1989 to 2011 in First Affiliated Hospital of Sun Yat-Sen University,and the patients were divided into 2 groups.There were 232 cases in group A,who were all diagnosed as chordee only on the basis of clinical symptoms or an erection induced by artificial stimulation before operation.All the 232 cases were corrected empirically without objective assessment by degloving the penis,dissecting superficial and deep fascia,and cutting off the urethral plate,and so on during operation.There were 25 cases in group B,who were all strictly implemented on classification diagnosis and treatment of chordee,in sponge saline injection test during operation and correction effect evaluation after operation.Chordee was classified according to different etiology and pathology:skin type,fascia-type,urethra type,sponge type and the glans of penis type.There were different operating methods in different ways of folding tunica albuginea.ResultsIn group A,86 patients (37％) had postoperative recurrence of chordee,25 patients ( 11％ ) had pain during erection after surgery,183 patients were satisfied with correction of chordee (79％).In group A,25 patients were in their adulthood when followed up,and 7 patients had IIEF-5 score ＜21 points.In group B,the single type of chordee among hypospadias were 7/25 (28％),merged type were 18/25 (72％).All patients were followed up without chordee recurrence or painless erection,and 100％ patients or families were satisfied with correction of chordee.The efficacy difference were statistically significant between the two groups in chordee correction.In folding tunica albuginea group in group B,the penile erection length was (4.58 ± 1.59) cm before the correction,and (6.16 ±2.54) cm after correction.In non-folding tunica albuginea group,penile erection length was (4.O1 ± 1.18 ) cm before correction,and (5.82 ± 1.51 ) cm after correction.The difference was not significant between the 2 groups in penile erection length (P ＞ 0.05 ).ConclusionsSurgeon should pay more attention to the correction,effect evaluated,classified etiology and pathological diagnosis of hypospadias and chordee.And the targeted selection of the correct treatment of chordee can further improve the therapeutic effect.Chordee of hypospadias can exist in single or merged according to the pathological classification.Chordee correction surgery can increase length of penis,and dorsal tunica albuginea plication had no significantly different effect on the length of the penis compared to other chordee corrective surgery.

Objective: : This study aims to investigate the relationship between aneurysm wall enhancement and clinical rupture risks based on the magnetic resonance vessel wall imaging (MR-VWI) quantitative methods. Methods: : One hundred and eight patients with 127 unruptured aneurysms were prospectively enrolled from Feburary 2016 to October 2017. Aneurysms were divided into high risk (≥10) and intermediate-low risk group (<10) according to the PHASES (Population, Hypertension, Age, Size of aneurysm, Earlier SAH history from another aneurysm, Site of aneurysm) scores. Clinical risk factors, aneurysm morphology, and wall enhancement index (WEI) calculated using 3D MR-VWI were analyzed and compared. Results: : In comparison of high-risk and intermediated-low risk groups, univariate analysis showed that neck width (4.5±3.3 mm vs. 3.4±1.7 mm, p=0.002), the presence of wall enhancement (100.0% vs. 62.9%, p<0.001), and WEI (1.6±0.6 vs. 0.8±0.8, p<0.001) were significantly associated with high rupture risk. Multivariate regression analysis revealed that WEI was the most important factor in predicting high rupture risk (odds ratio, 2.6; 95% confidence interval, 1.4–4.9; p=0.002). The receiver operating characteristic (ROC) curve analysis can efficiently differentiate higher risk aneurysms (area under the curve, 0.780; p<0.001) which have a reliable WEI cutoff value (1.04; sensitivity, 0.833; specificity, 0.67) predictive of high rupture risk. Conclusion : Aneurysms with higher rupture risk based on PHASES score demonstrate increased neck width, wall enhancement, and the enhancement intensity. Higher WEI in unruptured aneurysms has a predictive value for increased rupture risk.
