Neonatal jaundice or hyperbilirubinemia is a common occurrence in newborns.Most cases of neonatal jaundice have a benign course.Hyperbilirubinemia can be best understood as a balance between the production and elimination of bilirubin,with a multitude of factors and conditions affecting each of these processes.When an imbalance results because of an increase in circulating bilirubin ( or the bilirubin load)to significantly high levels( severe hyperbilirubinemia),it may cause permanent neurologic sequelae( kernicterus),which is preventable if the hyperbilirubinemia is identified early and treated appropriately.Phototherapy for jaundice is a common treatment in neonatal medicine and is used to prevent the neurotoxic effects of bilirubin.Phototherapy for hyperbilirubinemia should be based primarily on total serum bilirubin levels of the infant's age in hours and other factors that affect the risk of bilirubin encephalopathy.

Objective To learn about the mastery level of midwives and obstetric nurses about fetal monitoring knowledge.Methods 77 midwives and obstetric nurses attending a fetal monitoring education programme in Huaxi Second Hospital of Sichuan University were investigated by using a self-made questionnaire.Results Some respondents lacked of systematic training in fetal monitoring knowledge,and they could not accurately answer the purpose or contents of fetal monitoring,as well as the basic elements and related knowledge about fetal electronic monitoring.Most of the respondents focused on fetal monitoring in clinical practice,but neglected the corresponding frontier progresses.Conclusions The training and education on fetal monitoring knowledge should be strengthened to improve obstetric quality because of the unsatisfactory survey results in midwives and obstetric nurses.

[Summary] Glucagon-like peptide-1 ( GLP-1 ) as a new treatment of type 2 diabetes, not only has hypoglycemic effect, but also plays an important role in the regulation of lipid metabolism. GLP-1 plays a unique role in regulating lipid metabolism via lipid absorption and transport, fat formation and decomposition, hepatic lipid metabolism, and cholesterol transport.

Objective To determine the range of total serum bilirubin(TSB) of healthy term newborns during the first post natal week in Huainan region of Anhui province and provide the theoretical basis for the neonatal jaundice intervention in this region.Methods The bilirubin analyzer for capillary blood was used to measure TSB level of 1257 healthy term newborns during the first post natal week,P25,P50,P75 and P95 were recorded at every time point,the peak serum bilirubin(PSB) and the time it appeared was observed.50 blood samples were randomly selected and the TSB level was measured by the routine laboratory method,at the same time,the serum bilirubin level was measured by bilirubin analyzer for capillary blood.Then,the linear correlation coefficient of capillary blood bilirubin level and TSB level was calculated and statistically analyzed,and at last got the linear regression model.The newborns'skin xanthochromia coverage scales and TSB levels were recorded in order to get the corresponding TSB level in terms of xanthochromia coverage.Results In this study,the serum bilirubin P25,P50,P75 and P95 of 1 257healthy term newborns were 58.64μmol/L,72.51μmol/L L,102.44μmol/L,120.35 μmol/L,respectively in the first day,2nd day 105.41μmol/L,119.72μmol/L,150.18μmol/L,185.30μmol/L,3rd day 128.85μmol/L,157.951μmol/L,191.22μmol/L,227.61μmol/L,4th day 160.24μmol/L,191.40μmol/L,216.65μmol/L,277.49μmol/L,5th day 164.26μmol/L,179.51 μmol/L,209.88μmol/L,263.74μmol/L,6th day 131.87mol/L,172.73μmol/L,195.57μmol./L,231.26μmol/L,and the 7th day 118.94μmol/L,157.57μmol/L,204.83μmol/L,223.84μmol/L,with PSB 294.46μmoL/L appeared at the fourth day.The correlafionship was existed between the capillary blood bilirubin measurement and the routine laboratory method (r =0.948,t =21.067).The TSB level was (1 12.3 ± 6.2) μmol/Lwhen the xanthochromiawas on thehead,(165.1 ± 2 6.7) μmol/Lon the chest,(214.0 ±30.8) μmol/L on the belly,(268.5 ± 28.2) μmol/L on the knee or elbow,and ＞ 271.7μ mol/L on the palm or sole of the foot.Conclusion The TSB variation rang is 120.35 ～ 223.84μmol/L within 7 days after their birth in Huainan region of Anhui province,capillary blood bilirubin is reliable in measuring serum bilirubin level of newborns ; visual assessment of xanthochromia coverage is also an easy and feasible way of estimating serum bilirubin level initially.

Objective To explore which operation and the accuracy of the detection method is better by exploring the correlation among three bilirubin detection methods.Methods 50 hospitalized neonates within 7 days after birth with visual jaundice were randomly selected.The total serum bilirubin level was measured by the routine laboratory method.At the same time,the serum bilirubin level was measured by bilirubin analyzer for capillary blood and transcutaneous bilirubin(TcB) measurement,then calculated the linear correlation coefficient of TcB level and TSB level,capillary blood bilirubin level and TSB level respectively to analyze their statistical significance,and get the linear regression model at last.Results Close correlation is existed between the capillary blood bilirubin measurement and the routine laboratory method,also the transcutaneous bilirubin measurement and the routine laboratory method.Moreover,the former is better than the later.Conclusion Capillary blood bilirubin is reliable in measuring serum bilirubin level of newborns.

To investigate the damage on macrophage of the commercial peritoneal dialysis solution(CDS). Methods Macrophages were seperated from peritoneal fluid remained overnight of seven CAPD patients and TNF-a level of supernatant was determined and compared with those macrophages from uremic patients not yet recieving peritoneal dialysis. Results TNF-a levels of different glucose concentration decreased obviously in experimental group compared with control group, especially lower in 2.5% and 4.25% group. Conclusion In vivo experiment confirms that CDS possesses a long time inhibition on macrophage and this inhibition varies with different glucose concentrations.

Objective To study the chemical composition and the sources of indoor PM10 in some residential houses in Beijing. Methods PM10 samples were collected using cascade impactors in smoker's and non-smoker's homes in winter. The mass concentrations and enrichment characteristics of nineteen elements, such as Al, Si, and S in airborne particles were analyzed by proton induced X-ray emission (PIXE) and enrichment factor. Results The concentrations of 19 elements were higher in smoker's homes than those in non-smoker's homes in winter, especially K and S concentrations were 2-4 times of those in non-smoker's homes. Al, Si, S, K, Ca and Fe made greater contribution to concentrations of elements in PM10, of which K and S accounted for 72% of total elements in smoker's homes while Al, Si and Ca amounted to 57% of total elements in non-smoker's homes. Conclusion Al, Si, Ca, Ti and Fe come from natural sources while S, Zn, Pb, Cr, Cu, As, Cl and P originated from anthropogenic sources such as smoking, coal combustion and oil combustion.

Methods X-ray therapy was taken in no more than 24 hours after the keloids removing operations on 63 subjects, partly irradiating incision with 100～140kv X-ray,which was continued in the next three days,once for each day,till the total amount reached DT 1600～2000cGY. Results All postoperative incision healed in one-stage,all cases were followed up for 6～12 months, the new hyperplastic scar didn' t appeare on the incision of 57 subjects, while this happened on those of the other six with some improvement after operation than before operation. Rate of healing reached 90. 5% .Conclusion Cure of keloid by operation and closely following X-ray therapy can reach low recurrence and aesthetic effection,and it is worth popularizing in the clinic.

Objective To investigate the effect of XueBiJing injection(a concoction of Chinese herbs)on the expression of high mobility group box-1 protein(HMGB1)in the lung with acute lung injury of rats following delayed resuscitation after burn injury.Methods 78 male rats were randomly divided into sham scald group(n=18),scald group(n=30)and XueBiJing treatment group(n=30).In the scald group and XueBiJing treatment group,4ml/kg normal saline or XueBiJing was intravenously injected 2 hours after scald injury.In the latter two groups,rats were subjected to 30% TBSA full-thickness scald injury,and fluid resuscitation was delayed.The animals were sacrificed at 8h,24h and 72h after injury,respectively.Lung tissue samples were collected to determine the expression of HMGB1 mRNA and protein,and the activity of pulmonary myeloperoxidase(MPO).HMGB1 mRNA level was semi-quantitatively measured by RT-PCR using GAPDH as an internal standard,and protein expression of HMGB1 was determined by Western blot.Results Compared with sham scald controls,both mRNA and protein expressions of HMGB1 were significantly enhanced in the lung at 8-72h after scald injury(P

Objective To clarify whether the peritoneal equilibration test (PET)-determined solute transport groups defined by Twardowski fits patients in our medical center. Methods 158 initial standardized PET data since 1995 was selected and proportions of four transport groups were calculated according to Twardowski's criterion. Using the mean and standard deviations of 4-hour dialysis/plasma ratio of creatinine (D/Pcr), transport groups of our patients were re-determined. Patients were classified as follow: according to both two criteria, patients whose 4-hour D/Pcr in the range of high transport, low transport and average transport were classified as group H1, group L1 and group A, respectively; several average transport patients who changed to low transport after re-evaluation were classified as group L2; high transport patients who changed to average transport were classified as group H2. Every group was compared with clinical status in order to evaluate which criterion fit our patients. Results The 4-hour D/Pcr was 0. 70 ?0. 14 in our patients. The proportion of high, high-average, low-average and low transport were 21.5%, 44.9%, 17.8% and 5. 7% according to Twardowski's and 14. 6% , 33.5%, 33.5% and 18. 4% after re-evaluation. The ultrafiltration volume in group L2 was significantly higher than that in group A ( P
