Objective To explore the relationship of delivery of parenteral fat emulsion and lipid peroxidation,and to observe the safety and effectiveness of parenteral nutrition(PN)in infants with very low birth weight(VLBWI).Methods Thirty infants with VLBWI were randomly divided into 3 groups:the preterm infants received pareneral nutrition containing amino acids and dextrose and soluvit,while intralipid provided separately,intralipid were light exposed(group A,n=10)or light protected(group B,n=10).In group C(n=10),soluvit and vitlipid were co-administered with intralipid and light protected.All the prematures received PN for 7 days and 10 cases of VLBWI not recei-ving PN were collected as control group.Anti-oxidation level,ascorbate,blood glucose,oxygen saturation,serum biochemistry index and body weight were determined before and after experiment.Results Seven days after PN,the MDA concentrations in the test groups all increased(⊿dA was the most,⊿dB was the next,⊿dC was the least).For superoxidedimutuse(SOD)reduction concentrations,⊿dA decreased sharply,then was ⊿dB,⊿dc decreased little,The blood Vit C increase in group B and C were more than group A.Significant changes of MDA,SOD and Vit C existed among the group B,C and A.In the 3 test groups,bilirubin,albumin,prealbumin concentrations were higher after the experiment,but there were no significant changes compared with control group.No significant changes in blood biochemistry,oxygen saturations were found before and after the observation in every group.Conclusions Multivitamin preparations protect fat emulsion against light-induced formation of lipid hydroperoxides,and administering multivitamins with fat emulsion via dark delivery tubing provide a practical way of preventing peroxidation of the lipid while limiting vitamin loss.Furthermore,it is relatively safe to apply fat emulsion intravenously with suitable dose and infusion rate for a few days to VLBWI from the second day of birth who require partial parenteral nutrition.

OBJECTIVETo analyze the early clinical and radiographic outcomes of Hoffa fractures treated by a standard protocol of open reduction and internal fixation using headless compression screws combined with back buttress plate in a consecutive series of 8 Chinese patients.

METHODSOpen reduction and internal fixation was performed on all patients. The fractures were anatomically reduced and held temporarily by K-wire. If the ends of fractures were atrophic, autologous bone graft from the ipsilateral iliac crest was packed between the ends. Then the fracture fragments were fixed with AO 6.5 mm headless compression cannulated screws. At least two screws were used to provide rotational stability. One pre-contoured reconstruction plate was placed on the nonarticular surface posteromedially or posterolaterally as back buttress plate.

RESULTSAll the patients were followed up for at least 12 months (range 12-25 months). All fractures achieved anatomical reduction and healed clinically and radiographically. At recent follow-up, the mean flexion degree was 120.6° (range 110°-135°) and the mean extension degree was 2.5° (range 0°-5°). The average visual analogue scale score was 1.6 points (range 0-3). Six patients were assessed as excellent and 2 as good according to the hospital for special surgery knee score system. There were no superficial or deep infections, or hardware breakages. No patient had giving way or locking of the knee, though some had intermittent pain and swelling after strenuous exercise. Injury mechanism had significant influence on the functional outcome (P=0.046).

CONCLUSIONHeadless compression screws combined with back buttress plate and/or autologous bone grafting to treat old Hoffa fracture is one of effective measures. It would be conducive to not only fracture healing but also early exercise and functional recovery.

Objective To investigate the 7 kinds of respirovirus etiology of children with acute respiratory infection(ARI) in Wenzhou area from 2005 to 2006.Methods Three thousand nine hundred and seventy children with ARI visited the Yuying children's hospital were chosen,including 308 children with acute upper respiratory infection(URI) and 3 662 children with lower respiratory infection(LRI).Direct immunofluorescence(DIF) was used to detect the respiratory syncytial virus(RSV),adenovirus(ADV),influenza virus(IV) A and B,parainf-luenza virus(PIV) type 1,2,3 from nasopharyngeal secretions(NPS) collected from these patients.Results Among the 3 970 samples,1 773(44.7%) positive results were determined and the positive rate of RSV(36.2%) was the highest.The isolating rate of respirovirus were all conspicuous difference in sex(?2=9.2 P

The objective of this study was to investigate the effect of ZnPcH(1)-PDT on the lymphoma cells and its mechanism. Human Burkitt's lymphoma cell line CA46 and mouse lymphoma cell line P388 were selected as objects for study. The killing effect of ZnPcH(1)-PDT on cells were assessed by MTT method and colony formation assay; the cell death patterns were analyzed by AO/EB fluorescence stain, TdT-mediated dUTP nick end labeling (TUNEL), DNA ladder assay; and the different proportions of each death pattern were determined by Annexin-V(-FITC)/PI double stains. The results showed that ZnPcH(1)-PDT displayed anti-proliferation effect on both CA46 cells and P388 cells in dose-dependent manner. CA46 cells were less sensitive to PDT than P388 cells (p < 0.05). Furthermore, PDT could induce cell apoptosis in time-dependent manner. The rate of cell apoptosis increased in the PDT-treated cells. The results of Annexin-V(-FITC)/PI stain indicated that early apoptosis was the main death pattern in the PDT-treated CA46 cells, while early apoptosis and necrosis were the main death model in the PDT-treated P388 cells. It is concluded that ZnPcH(1)-PDT can effectively inhibit lymphoma cell proliferation and induce cell apoptosis.

The study was to observe the effect of rhG-CSF (lishengsu) in treating leukopenia caused by radiotherapy and chemotherapy in patients with breast cancer. 100 cases of breast cancer received modified radical mastectomy were randomized into two groups with the same treatment of one cycle chemotherapy using the protocol of CAF at two weeks after the operations and then radiotherapy. The patients in treated group received rhG-CSF 75 micro g per day s.c. for 5 - 7 days constantly, and additional 3 - 5 days according to leukopenia during radiotherapy. The patients in control group did not receive rhG-CSF during the chemo- and radio-therapy. The results shows that nadir of WBC and neutrophil counts in the treated group was higher than that in control significantly. In conclusion, effect of lishengsu on leucopenia in process of chemotherapy and radiotherapy shows definite therapeutic effect, the side effects are not remarkable.

OBJECTIVETo compare the epidemiological and clinical features of lower respiratory tract infection (LRTI) caused by influenza virus A (IVA) and influenza virus B (IVB) in children.

METHODSThe clinical data of 366 children with LRTI caused by influenza virus (IV), who were hospitalized in Yuying Children′s Hospital of Wenzhou Medical University between 2010 and 2014, were analyzed retrospectively, and there were 272 cases caused by IVA and 94 cases caused by IVB.

RESULTSIV was mainly prevalent from December to March of the next year, with the predominance of IVA. There were small peaks of IVA prevalence in July or September every other year, and IVB was prevalent from December to March of the next year every other year. The children with LRTI caused by IVA alone had a significantly higher white blood cell (WBC) count and significantly higher percentages of children with increased WBC, abnormal serum sodium, and abnormal serum potassium than those caused by IVB alone (P<0.05). However, there were no significant differences in age, sex, underlying diseases, clinical manifestations, and co-infection rate with bacteria or atypical pathogens between the two groups (P>0.05). The rate of co-infection with respiratory syncytial virus (RSV) was significantly higher in the IVB group than in the IVA group (P<0.01).

CONCLUSIONSIVA is prevalent in winter and spring every year and has small peaks in summer every other year, while IVB is prevalent in winter and spring every other year. Compared with IVB, IVA causes more cases of increased WBC and electrolyte disturbance. The children infected with IVB are more likely to be co-infected with RSV. The children with LRTI caused by IVA and IVB have similar clinical manifestations.

OBJECTIVETo map the high myopia gene in a Chinese family with autosomal dominant high myopia.

METHODSA family with autosomal dominant high myopia in three generations was collected. Eighteen short-tandem-repeat markers on previously reported loci linked to high myopia were chosen for genotyping and two-point linkage analysis was carried out.

RESULTSThe spherical equivalent of affected individuals ranges from -6.00D to -20.00D and the genetic pattern is autosomal dominant. The LOD score was less than -1 in all 18 microsatellite markers, indicating that there was no linkage between these markers and the high myopia related genes in this family.

CONCLUSIONA novel myopia locus for high-grade myopia may exist in the kindred. Genome-wide scan will be needed to determine this novel locus.
