Objective To study the variation of serum IL-18 and TNF-? in infants with cytomegalovirus (CMV) hepatitis before and after treatment. Methods The levels of serum IL-18 and TNF-? in 36 infants with CMV-hepatitis before and after treatment and in 21 normal infants were detected by enzyme linked immunosorbent assay (ELISA). Results Serum levels of IL-18 and TNF-? in infants with CMV-heptitis were obviously higher than those in normal infants (P

Objective To investigate the differences of apparent diffusion coefficient(ADC)value in normal breasts and to evaluate the correlation between ADC value and corresponding histology.Methods Sixty-two normal breasts including 42 normal breasts of 42 patients with unilateral lesions and 20 normal breasts of 10 volunteers were studied.The ADC value of all 62 normal breasts were calculated when b value was given from 1000 to 0 s/mm~2,1000 to 500 s/mm~2and 500 to 0 s/mm~2.The MRI features of 60 normal breasts were classified into 3 types(dense,lobular-speckled,degenerative types)according to Wolf's classification and histology.Results DWI and ADC images were different in 3 types of normal breasts because of different histologic structures.The mean ADC value of the dense type breasts was(1.70? 0.37)?10~(-3)mm~2/s,the lobular-speckled type was(1.93?0.46)?10~(-3)mm~2/s and the degenerative type was(1.18?0.65)?10~(-3)mm~2/s(F=12.998,P=0.000).There were no significant differences between the dense type and the lobular-speckled type(F=2.167,P=0.147),but significant differences between the dense type and the degenerative type,the lobular-speckled type and the degenerate type(F=5.593 and 19.128;P=0.029 and 0.000).When b value decreased,the ADC value of the dense type and the lobular- speckled type increased correspondingly,but the degenerative type didn't increase apparently.Conclusion ADC value was influenced by histologic structures in normal breasts and also was influenced by b value in the dense type and lobular-speckled type breasts.

Objective:To explore the diagnostic value of low dose multi-detector computed tomography urography (CTU) in patients with urinary tract diseases.Methods:Sixty patients who were treated with CTU from January 2015 to December 2016 were included in this study.All patients were divided into three groups according to the random number method.Group Ⅰ (160 mA tube current),group Ⅱ (120 mA tube current) and group Ⅲ (80 mA tube current),the selected patients were taken to the corresponding tube current CTU.The diagnostic efficacy of three groups of uropathy was analyzed,and the three groups of CTU imaging results,iodine contrast agent dosage and radiation dose of the situation were compared.Results:The dose of iodine contrast agent and the effective dose of radiation in group Ⅲ were lower than those in group Ⅰ and group Ⅱ,and the dose of radiation and dose of iodine contrast agent in group Ⅱ were lower than those in group Ⅰ (P＜0.05).The difference of CTU imaging scores between the three groups was not statistically significant.Conclusions:The diagnostic value of low-dose (80 mA tube current) CTU in urinary tract diseases is similar to the high-dose CTU,with the iodinated contrast agent dosage and effective dose of radiation reduced significantly,which is worth of clinical promotion.

OBJECTIVETo investigate the relationship between perinatal risk factors such as premature, low birth weight, small for gestational age and childhood cerebral palsy (CP).

METHODSA cross sectional survey was carried out among 305,263 children aged 1 - 6 years old in seven cities of Jiangsu Province, China from May to July 1997. The perinatal risk factors were analysed.

RESULTSFour hundred and eighty-four cases of CP were found among this population. The prevalence of CP for children aged 1 - 6 years old was 1.59 per thousand. The prevalence of CP were strongly correlated to prematurity (RR = 25.16), low birth weight (RR = 19.63), and also highly correlated to small for gestational age (RR = 4.34). For smaller groups divided by small for gestational age (SGA), appropriate for gestational age (AGA), large for gestational age (LGA) and then by gestational age, prematurity was found to be at high risk in SGA (RR = 9.29), AGA (RR = 28.34) and LGA (RR = 21.41) groups. For groups divided by gestational age and then by SGA, AGA and LGA, SGA was found to have significantly high risk in premature (RR = 1.45), mature (RR = 4.41) and postmature (RR = 3.19) groups. Nine groups were divided by the gestational age along with SGA, AGA and LGA, rates of CP were found to be significantly higher in most groups than in the term AGA group. Compared with the rate of CP in the term AGA group, the RR were calculated and showed as followings (from higher to lower), premature SGA (RR = 40.99), premature AGA (RR = 28.34), premature LGA (RR = 21.08), postmature SGA (RR = 8.39), mature SGA (RR = 4.41) and postmature AGA (RR = 2.63).

CONCLUSIONPrematurity and small for gestational age are both independent risk factors for cerebral palsy. Postmaturity and large for gestational age are not risk factors.

OBJECTIVETo summarize the clinical experience in repair of deep burn and traumatic wounds with combined transplantation of different types of pedicled skin flaps in lower extremities.

METHODSTwo hundred and thirty-six patients with 271 deep wounds in lower extremities after burn or trauma were repaired with muscular skin flaps, local fascial flaps and island flaps with vascular pedicle (more than 20 types) in our department from Jan. 1998 to Sept. 2008.

RESULTSComplete necrosis of skin flaps occurred in 1 case, congestion and necrosis over the edge of skin flaps occurred in 3 cases, which were healed after grafting, and other skin flaps survived well with soft texture. Skin flaps were too bulky in 26 cases, among them 17 cases were thinned, and the appearance of other skin flaps were satisfactory. In 68 patients with functional region injury were recovered to certain extent without contracture.

CONCLUSIONSSkin flaps with pedicles, multiple transplantations if necessary, can repair deep wounds satisfactorily in lower extremities after deep burn or trauma injury.

AIMTo separate and identify the chemical constituents of the aril of Torreya grandis cv. Merrilli.

CONCLUSIONThese compounds were isolated from this plant for the first time, and compound III is a new compound.

BACKGROUNDUnplanned extubation is associated with adverse outcomes in intensive care unit. The massive burn patient differs from other critically ill patients in many ways. However, little is known about the unplanned decannulation (UD) in Burn Intensive Care Unit. This paper describes the special features of the circumstances and outcome of UD of tracheotomy tube in massive burn patients.

METHODSA case series study was performed between January 1999 and December 2008 and UD of tracheotomy tube was analyzed retrospectively. A total of 21 patients with 29 UD events were identified. Demographic data, diagnosis, intervention, UD events and outcome of UD patients were collected. Differences in proportions were compared using the chi-square (χ(2)) or Fisher's exact test.

RESULTSPatients with UD were often burned with head and neck (67%) and combined with inhalation injury (62%). The majority of them (76%) were transferred patients, occurred early (55%) and were accidental UD (79%). UD events tended to happen in day shift (90%) and to be associated with the medical procedure that was performing by caregivers at besides (79%). Loose of the stabilizing rope, medical procedure and tracheotomy malposition were the main causes of UD. Early UD and reintubation failure were associated with patients' death.

CONCLUSIONSUD happened to massive burn patients can lead to patient death. Careful management of respiratory tract was essential for massive burn patients.

Objective Feasibility of using MNA cell-culture inoculation test to detect and isolate the street rabies virus. Methods Using MNA cell-culture inoculation test, fluorescent antibody test (FAT) and sandwich ELISA with double-antibodies to detect 33 specimens of street rabies virus, 20 specimens of negative canine brains and 4 specimens of healthy mice brains. Results 33 specimens of street rabies virus were positive to the cell-culture inoculation test but the others were negative. The concordances of MNA cell-cultured inoculation test with FAT and sandwich ELISA with double-antibodies were both 100%. Conclusion MNA cell-culture inoculation test appeared to be both highly sensitive and specific in detecting the street rabies virus, and could be used in detection and isolation of the virus.
