Malnutrition has traditionally been regarded as a global concern,especially in the developing countries. Malnutrition seems more prevalent in hospitalized patients, with potentially serious consequences, it may increase susceptibility to infection and mortality and lengthen the stays in hospital,which lead to additional health care costs. Along with the development of the screening tools,it plays an increasingly important role in the nutritional problems in adults. Recently several nutritional screening tools have been applied in pediatrics,but the lack of the universal acceptable tools is still a problem demanding prompt solution. This review aims to compare the nutritional screening tools that are currently available in clinic and their drawbacks in daily work.

AIM:To observe the efficacy, complications and ocular surface tear dynamics of the treatment for pterygium combined with conjunctivochalasis by inferior limbal-stem-cell transplantation.
METHODS: All 30 patients ( 46 eyes ) diagnosed as pterygium combined with conjunctivochalasis in our hospital from December, 2010 to December, 2012 with a mean age of 61. 2y (SD 7. 2, range 49-75) were subjected to observation. After excision of nasal pterygium, an equivalent size of conjunctival flap linked with corneal limbal stem cell from inferior limbus was transplanted to the exposed sclera. Afterwards, the inferior bulbar conjunctiva was trimmed and fixed onto surface of sclera and inferior corneal limbus. After one-year follow-up, the comparisons regarding vision acuity between pre-operation and post-operation ( 1mo later ) as well as ocular-surface tear dynamics changes including several indexes like altitude and integrity of tear meniscus, break-up time ( BUT ) , corneal fluorescein staining and chloramphenicol gestation test before and 3mo after surgery were made. The operative complications and the recurrence rates 1y after operations were recorded.
RESULTS: Median visual acuity was 0. 2 (0. 04-0. 6) before the operation and median visual acuity was 0. 4 (0-04-1. 0) 1mo after the operation. Of total 46 eyes in 21 eyes ( 45. 7%), visual acuity improved. No vision changes were found in other 25 eyes ( 54. 3%). Significant difference ( P<0. 01 ) of vision acuity before and after surgery was found. In addition, break-up time ( BUT) , corneal fluorescein staining and chloramphenicol gestation test and altitude and integrity of tear meniscus show better results 3mo after surgery than that of pre-operation, which showed statistically significant ( P <0-05). After 1y follow-up, 33 eyes (71. 7%) healed while problems in 11 eyes ( 23%) were relieved. The total efficacy rate was 95. 6%. Nonetheless, invalid surgeries were noticed in two eyes ( 4. 4%) that affected by recurrence of pterygium. The 33 eyes (71. 7%) affected by conjunctivochalasis was cured in terms of subjective evaluation and improved in 9 eyes (19. 6 %), but 4 eyes (8. 7%) exhibited no evident improvement in terms of subjective complains. Total efficacy was 91. 3%. The 41 eyes (89. 1%) were reported to be normal while 5 eyes ( 10. 9%) were revealed to be abnormal in terms of objective therapeutic evaluation. And this condition was so-call conjunctivochalasis recurrence with a recurrence rate of 10. 9%. No proliferation of granulation, narrowing inferior fornix and malfunction of eye movements was found.
CONCLUSION: Inferior - limbal - stem - cell transplantation to treat pterygium combined with conjunctivochalasis obtains better results. It proves to eradicate or relieve symptoms of patients effectively and ameliorate ocular-surface tear dynamics.

Objective To identify the molecular components involved in acquired methotrexate-resistance of human choriocarcinoma. Methods Methotrexate-resistant cell line(JAR/MTX) was derived from JAR cell line by exposed to intervally and progressively increasing higher concentration of MTX. cDNA microarray analyses of JAR/MTX and its parental cell line JAR were performed. Results JAR/MTX was established after one year with stable resistance. Its resistant index to MTX was 7.3. Nine genes were differential expressed between JAR/MTX and JAR cells. INSR,SLC1A3,SAT,HBB,and FLJ12443 were underexpressed and HS1,TXNRD1,TAGLN2,and EEF2 were overexpressed in JAR/MTX cells. Conclusion The cDNA microarray system showed that several alterations of gene expression were present in acquired methotrexate-resistance of human choriocarcinoma.

Objective To investigate the clinical significance of peripheral blood parameters including immature reticulocyte fraction (IRF) in monitoring the hematopoietic recovery of patients with acute myeloid leukemia aftcr receiving consolidation chemotherapy with high dose cytarabine (HDAC).Methods The peripheral blood parameters,including absolute neutrophil (ANC) and platelet (Plt) counts as well as IRF,were measured by Sysmex XE-2100 automated hematology analyzer before and after consolidation chemotherapy with HDAC in 30 patients with acute myeloid leukemia.These peripheral blood parameters were further statistically analyzed and compared.Results Following consolidation chemotherapy,the median time to recovery for ANC,Plt and IRF was (9.2±2.5) days,(11.3±3.7) days and (5.0±2.6) days,respectively.In comparison with ANC and Plt recovery,IRF showed significantly early recovery (P ＜ 0.05).Additionally,ANC raised preceding Plt recovery (P ＜ 0.05).However,the median recovery time of ANC,Plt and IRF showed little difference among these patients further subgrouped according to FAB and risk based classification (P ＞ 0.05).Conclusion IRF is an early indicator for the hematopoietic recovery of patients with acute myeloid leukemia following consolidation chemotherapy with HDAC,which could provide important clinical information to evaluate therapeutic efficacy.

OBJECTIVETo study the correlation between Chinese medical types of coronary heart disease (CHD) [i.e., phlegm turbidity syndrome (PTS) and qi deficiency syndrome (QDS)] and their metabolites.

METHODSRecruited were 65 CHD patients including 37 cases of PTS and 28 cases of QDS. Serum endogenous metabolites in the two syndrome types were determined by gas chromatograph-mass spectrometer-computer (GC/MS), and their differences between their metabolic profiles analyzed.

RESULTSMore than 100 chromatographic peaks were totally scanned. Chromatograms obtained was matched with mass spectrum bank, and finally we got the category contribution value of 46 kinds of substances. Results of MCTree analysis showed patients of PTS and patients of QDS could be effectively distinguished. Compounds contributing to identify the two syndromes were sequenced as serine, valine, 2 hydroxy propionic acid. Comparison of metabolites showed contents of serine and 2 hydroxy propionic acid were higher in patients of PTS than in patients of QDS (P<0.05).

CONCLUSIONThe differences in the metabonomics of CHD TCM syndrome types could provide material bases for TCM syndrome differentiation of CHD, indicating that metabonomics technologies might become a new research method for TCM syndrome typing.
