Objective To establish normal reference intervals of plasma and urine neutrophil gelatinase-associated lipocalin (NGAL) in children′s hospital.Methods A total of 183 fresh EDTA anticoagulant samples and 125 fresh urine in healthy children were collected from May 2014 to October 2014.According to the CLSI C28-A2 ,the unilateral upper limit 95% was established the normal reference value in different age group.Results There was significant difference in four groups (P<0.05).The normal reference intervals of plasma NGAL in healthy children:0 to <7 months;<291.28 μg/L;7 months to <5 years old;<150.87 μg/L;5 years old to <9 years old:<127.93 μg/L;9 years old to ≤16 years old:<161.74 μg/L;the normal reference intervals of healthy children urine NGAL:0 to <7 months:<257.31 μg/L;7 months to <5 years old:<201.55 μg/L;5years old to <9 years old:<197.69 μg/L;9 years old to ≤16 years old:<151.46 μg/L.Plasma and urine NGAL results in neonatal group were higher than the other three groups.Conclusion The normal reference intervals of plasma and urine NGAL in children′s hospital is established.this could provide clinical evidence for the diagnosis and treatment of acute renal injury in pediatric patients.

Objective To evaluate eutopic endometrial blood supply and vessels in patients with endometriosis(EMs) with contrast enhanced ultrasound (CEUS),to explore a newmethod to estimate vascularization of eutopic endometrium in EMs patients.MethodsThirty patients with EMs were enrolled and 20 patients who were diagnosed as other gynecological diseases as control.Informed consent of each case was obtained. AllcasesunderwentconventionalultrasoundexaminationandCEUSexamination.Characteristics of CEUS in each patients were observed and analyzed using off-line Qontrast software.Parameters of CEUS including peak intensity(PEAK),time to peak(TTP),regional blood volume(RBV),regional blood flow(RBF) were obtained automatically.ResultsComparing with control group,the eutopic endometrium in EMs group presented higher enhancement.The parameters of CEUS,including PEAK,TTP,RBV,RBF were (41.18 ± 3.29) dB,(29.01 ± 4.46) s,(29.07 ± 4.59) ml,(48.61 ± 5.35) ml/min in EMs group and (13.36 ± 2.34)dB,(24.59 ± 2.29)s,(26.51 ±- 3.80)ml,(48.71 ± 3.80)ml/min in controls respectively,the value of PEAK in EMs group was higher than that of controls ( P =0.000).Conclusions CEUS can be regarded as a new method which can be used to assess vascularization of eutopic endometrium in endometriosis.

Objective To investigate the clinical features of patients with multiple sclerosis (MS) and restless legs syndrome (RLS) and to further examine relevant factors that may contribute to the co-occurrence of MS and RLS.Methods Seventy MS patients were recruited in the present study.The RLS screen was further performed in MS patients based on the diagnostic criteria for RLS.MS patients with RLS were designated as the case group and MS patients without RLS served as the control group.The clinical data including age of MS onset,MS duration and clinical disability by the expanded disability status scale (EDSS) were analyzed.Results There were 12 MS patients with RLS in total 70 MS patients and the incidence rate was 17.1％.The average age of MS onset in the RLS group was (47.6 ± 10.0) years,and (40.1 ± 10.4 ) years in the control group.The difference of average age of MS onset was found to be significant (t =2.29,P =0.030).The average history of MS in the RLS group was ( 12.6 ± 6.8 ) years,and ( 8.2 ± 6.6) years in the control group ( t =2.10,P =0.039).The average EDSS of the RLS group was 4.5 ±2.5,and 2.5 ±2.0 in the control group (t =3.02,P =0.004).There was no significant association between RLSRS and EDSS in MS patients with RLS (P =0.15).Conclusion The incidence rate of RLS in MS patients was high.Among patients with MS,RLS was associated with older age,longer MS duration,and more severe disability.

OBJECTIVE:To investigate the situation of antibiotic resistance of S.pneumoniae(Sp)of clinical isolates from children in Guangzhou.METHODS:The authors cultured,isolated and identified the Sp strains from nasopharyngeal secretion of patients who visited Guangzhou children's hospitals because of upper respiratory tract infections in2000and2001.The paper strip method and E-Test of antibiotic susceptibility were done for157isolates.RESULTS:The penicillin resistant Sp(PRSP)isolates accounted for53.5%.PRSP isolates showed a higher resistance to other?-lactam antimcrobal,erythromycin and trimethoprim/sulfamethoxazole as compared to penicillin susceptible Sp(PSSP)isolates.More than90%of PRSP were mul?tidrug resistant strains.The strains of Sp were susceptible to amoxicillin/clavulamic acid and ceftriaxone.Strains had decreaced susceptibility(59%)to cefuroxime.In2001,the rate of cefaclor resistance was56%.The prevalence of erythromycin resistant Sp in this study was up to78%.The rate of tetra-cycline resistance were87.9%.Trimethoprim/sulphamethoxazole(TMP/SMX)resistant rate was as high as69%.The chloramphenicol resistant isolats were in stable low levels(33.3%).CONCLUSI_ ON:The resistant Sp isolated from children with respiratory tract infections in this area would be a severe problem.PRSP rate was increased and was characterized by a multi-resistance to erythromycin,tetracycline and TMP/SMX.

Objective To analyze the effects of fetal reduction in early pregnancy on obstetric and neonatal outcomes of spontaneously or selectively reduced multiple pregnancies produced by in vitro fertilization-embryo transfer (IVF-ET). Methods Retrospective study of 6917 clinical pregnancies from IVF-ET cycles, including 754 multiple pregnancies divided into two groups according to the remaining fetus number: reduced singleton group (n=599) and reduced twin group (n=155); and maternal and neonatal outcomes of two groups were compared to primary singleton group (n=3589) and primary twin group (n=2574). Results The rate of pregnancy complication [9.85%(59/599) versus 6.21%(223/3589)], preterm birth [19.37%(116/599) versus 10.73%(385/3589)], low birth weight [9.71%(56/577) versus 4.57%(152/3324)], perinatal death [0.69%(4/577) versus 0.12%(4/3324)] and malformation [2.95%(17/577) versus 1.02%(34/3324)] in reduced singleton group were significantly higher than those in primary singleton group (all P<0.01). There were no significant differences between reduced twin group and primary twin group (all P>0.05). In reduced singleton group, birth defect rate was 2.95%, which was higher than those of the other three groups (P<0.05), in this group spontaneous pregnancy reduction accounted for 89.3%(535/599). Conclusions (1) The rate of pregnancy complication, preterm birth, low birth weight, perinatal death and malformation in reduced singleton group are still higher than primary singletons, suggesting embryo reduction only is a compensated method in multiple pregnancies. Limiting the number of embryos transferred is the essential solution. (2) The rate of birth defect in spontaneous pregnancy reduction group is higher, so prenatal examination should be reinforced in this group.

Objective To evaluate the feasibility of diagnostic and therapeutic peroral direct cholan-gioscopy (PDCS)using an ultra-slim upper endoscopy assisted by a snare.Methods Between November 2014 and January 2015,8 patients underwent PDCS with assistance of an ultra-slim endoscopy.After endo-scopic papillary balloon dilation,the duodenoscopy was withdrew,an ultra-slim endoscopy was inserted di-rectly into the biliary tract assisted by a snare,and biopsy or laser lithotripsy was performed.The snare was closed tightly in the bent portion of the scope,and the snare was pulled while scope shaft had to become the form of U loop by counterclockwise rotation,in order to advance the scope into common bile duct.Results PDCS succeeded in all eight cases,one common hepatic duct adenoma was diagnosed by biopsy,and con-firmed by surgery;one benign biliary stricture was diagnosed by PDCS;laser lithotripsy was successfully per-formed in 4 patients with large CBD stones;bile duct clearance was verified by PDCS in two patients who was suspected of residual CBD stones.No perforation,bleeding or post-operative pancreatitis was found.Con-clusion PDCS using an ultra-slim gastroscopy assisted by a snare is a safe,simple and practical procedure in the diagnosis and treatment of biliary tract diseases.

Objective: To observe the clinical efficacy of combination of Dahuang Mugong decoction(DMD,大黄牡公汤) and sequential colon dialysis in treatment of chronic renal failure(CRF) and explore its potential mechanism.Methods: Nintyeight patients with CRF were treated with sequential colon dialysis and DMD.Besides the observation on the clinical symptoms and signs,the serum levels of blood urea nitrogen(BUN),serum creatinine(SCr),uric acid(UA),serum phosphorus((SP),inorganic),Ca~(2+) and(albumin)(Alb) were measured with autoanalysis machine and the optical density(A_(450) value) of medium molecule substance(MM) with(nephelometer) between pre treatment and posttreatment.Results: The(accumulated) score of the clinical symptoms and signs were decreased with the combination of DMD and(sequential) colon dialysis(P

ObjectiveTo investigate the clinical characteristics of the inpatients suffering from dengue fever in order to provide references for better diagnosis and treatment.Methods The clinical data of 158 dengue fever patients admitted to the First Affiliated Hospital of Sun Yat-Sen University from July 23rd to October 31st, 2014 during the 2014 epidemic in Guangzhou area were retrospectively analyzed, including general clinical manifestations, conventional examinations, pathogenesis, and prognosis.Results The mean age of the 158 patients was (56±20) years, with half of them over 60 years old (79 cases). Among them, 94 (59.49%) were male.① The common manifestations included fever (100%), headache (70.89%), myalgia/bone soreness (62.03%), and skin rash (54.43%). Bleeding and plasma leakage were found in 25.95% and 14.56% of the patients respectively.② Laboratory examination:leucopenia (75.32%) and thrombocytopenia (77.85%) were found, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were elevated in 57.59% and 77.85% of the patients respectively. However, elevation of blood hematocrit was rare (1.27%).③ It was found that in the acute phase (0 - 5 days of the onset), serum dengue virus antibody IgM (DF-IgM) was positive in 63.54% of the patients (61/96), and 92.62% (113/122) of patients were dengue virus RNA (DENA-RNA) positive.④ The rate of comorbidity in this study was 55.06% (87/158), including hypertension (27.22%) and type 2 diabetes (15.82%), which were the two most common co-morbidities.⑤ All the patients were given supportive therapy to prevent complications. They were also isolated for more than 5 days after onset, and at least for 24 hours after subsidence of fever in addition.⑥ The criteria for the diagnosis of severe dengue were fulfilled in 18 patients (11.39%). One patient died of massive hemorrhage from gastro-intestinal tract, and 1 patient voluntarily left hospital with untreated multiple organ dysfunction syndrome (MODS). Another 2 patients of dengue fever died from primary cardio-cerebrovascular disease, and the remaining 154 patients (97.47%) fully recovered with supportive therapy and complication prevention measures.Conclusions The clinical manifestations of inpatients with dengue fever in this study were typical, and they manifested a higher incidence of severe illness. DENA-RNA could be a sensitive indicator for early pathogenic diagnosis. With symptomatic and supportive therapy, most patients had a good outcome. However, early diagnosis and clinical interventions of severe dengue still need further studies.
