OBJECTIVE To analyze risk factors in order to provide scientific gist in diagnosis and treatment of central venous catheter related sepsis(CRS) in patients with total parenteral nutrition(TPN). METHODS To make comparison of the 57 cases of CRS with 423 cases of non-CRS during 1998-2002.First,monovariable chi-square test and then non-condition Logistic regression analysis of the markedly different factors in SPSS10.0 were conducted. RESULTS The major risk factors might be infectious disease,duration of central venous catheter in,location of catheter, type of catheter and material of catheter,and serum protein

Objective To study the clinical characters,the mode of inheritance of osteogenesis Imperfecta in a Chinese Family and effect of bisphosphonate on Osteogenesis Imperfecta.Methods Clinical data of proband and their family members were collected.The family patterns were mapped.clinical features were summarized and analyzed.Results(1)Clinical features:There are sixty members of four generations in the family.20 cases including proband's mother and cousin were diagnosed as having OI type Ⅰ based on clinical manifestations.15 cases of blue sclera,16 cases of dentinogenesis imperfecta,5 cases of hearing loss and 3 cases of fracture.Thyroid cancer and Turner's syndrome was found in Proband's mother and cousin respectively.(2)The genetic map showed that the disease was autosomal dominant inheritance.(3)Treatment:The proband,her mother and her cousin were treated with alendronate for two years.Bone pain relieved and bone mineral density increased significantly,and no fracture occurred so far.Conclusion(1)This OI family was diagnosed as having OI type Ⅰ.The mode of inheritance is autosomal dominant inheritance.(2)Bisphosphonates may be an effective drug for treatment of OI.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
