Objective To evaluate the clinical effect of the enteral nutrient(Pediasure) on making improvements in nutritional status of children with anorexia.Methods Thirty children were treated with pediasure for 2 months, twice a day, and height(Ht),weight(Wt),AG,TSF,SSF,ASF,RBC,Hb were measured before and after treatment and their appetites,alimentary canal reactions were recorded.Results Compared with the effects after 2 months, the average Ht,Wt,AG,SF all increased, and there was significant difference between pretreatment and after treatment(P0.05). All of the 30 children had no adverse reactions during treatment.Twenty-two children (73.33%) had better appetites and increased the amount of eating after treatment.Conclusion The study suggests that pediasure may be safely used in the treatment of children′s anorexia and effectively improve patients′ nutrition without adverse reactions.

Objective To evaluate the MR imaging and CT appearances of focal nodular hyperplasia (FNH) of the liver and improve the accuracy of diagnosis in FNH. Methods 6 patients with solitary FNH underwent MR exiamnation. Dynamic Gd-DTPA enhancement were performed in all the lesions. Of the 6 patients, three underwent CT plain and dynamic contrast scan; one underwent CT plain scan. More attention was payed to the atypical appearances. Results Atypical lesion appearances ineludod:apparent hypointensity on T1 WI and hyperintensity on T2WI,diffusly heterogeneous enhancement in arterial phase, pseudocapsule enhancement in delayed phase;the dynamic contrast MR and CT appearance in each phase were not all similar. Conclusion MR and CT especially dynamic contrast enhancemenl is of great value to the diagnosis of FNH. The atypical appearances of FNH shoud keep in mind to avoid misdiagnosis.

Objective To analyze negative lymph nodes of 34 non-small cell lung cancer(NCLC) patients with total correction by means of fluorescent quantitation PCR and immunohistcchemistry,and to form molecular bi- ology staging.Methods Clinical data and tissue samples of 193 lymph nodes were collected from 34 patients under- going resection for non-small cell lung cancer.Using fluorescent quantitation reverse transcription-polymerase chain reaction(RT-PCR) and immunohistochemistry method,lymph nodes were examined for CEA gene mRNA,P53 and CK to form molecular biology staging.All the patients were followed-up for an average of forty months.Results The CEAmRNA was identified in 21.7% (42/193) lymph nodes negative patients from 17 patients(17/34,50%); TMN staging was up-regulated in 8 patients;positive lymph nodes were increased in 9 patients.P53 and AE1/AE3 were identified 9.8%(19/193) from 11 patients,18.6 % (36/193)from 15 patients,separately;TMN staging was up-regulated in 2 patients of P53 examination and 5 patients of AE1/AE3 analysis;positive lymph nodes were in- creased in in 7 patients of P53 examination and 11 patients of AE1/AE3 analysis.There was obvious statistical sig- nificance in them,but the molecular biology staging based on the three markers was not an independent factor on re- currence and metasis of lung cancer.Conclusion CEAmRNA.P53 and AE1/AE3 analysis could find lung cancer micrometasis more sensitively to form molecular biology staging which was relative to the prognosis,but not an inde- pendent prognostic indicator.It might be good to the therapy strategy after operation.

OBJECTIVETo investigate the expressions of the EZH2 protein and EZH2 mRNA in human prostate cancer (PCa) and their correlation with the clinicopathologic parameters.

METHODSA tissue microarray (TMA) was constructed, which contained 48 dots of formalin-fixed paraffin-embedded tissue samples of human PCa. The expressions of the EZH2 protein and EZH2 mRNA in the samples were detected by immunohistochemistry (EnVision) and in situ hybridization (ISH). Another 15 cases of human benign prostate hyperplasia (BPH) and 12 cases of human prostate intraepithelial neoplasia (HGPIN) were taken as controls.

RESULTSThe positive rates of the EZH2 protein and mRNA were significantly higher in PCa than in BPH and HGPIN (87.5% vs 13.33% and 16.67%, 81.25% vs 6.67% and 16.67%, P < 0.05). The positive expression of the EZH2 protein was 96.67% and 72.22% in the Gleason score > or = 7 and Gleason score < or = 6 groups, respectively, with significant differences between the two groups (P < 0.05). The positivity of the EZH2 protein was significantly related to the TNM stage, increasing with tumor progression (P < 0.05), but not to age and serum PSA (P > 0.05), and so was that of EZH2 mRNA to TNM stage (P < 0.05), but not to age, serum PSA and Gleason score (P > 0.05). When the above characteristics were regarded as two-level discrete variables, both the EZH2 protein and EZH2 mRNA showed statistically significant differences in the positive expression rate (P < 0.05).

CONCLUSIONThe over-expressions of the EZH2 protein and EZH2 mRNA may play an important role in the pathogenesis and progression of PCa and provide some reference indexes for estimating the malignancy, progression and prognosis of PCa.

OBJECTIVETo compare the clinical effects of unilateral pedicle screw fixation (uni-PS) assisted by Quadrant system and bilateral pedicle screw fixation (bi-PS) for the treatment of lumbar degenerative diseases.

METHODSFrom October 2008 to October 2010,102 patients with lower back pain, unilateral lower limb radiating pain or paraesthesia were treated with pedicle screw fixation and lumbar interbody fusion. There were 67 males and 35 females with an average age of 51.5 years ranging from 34 to 69 years. The patients were randomly divided into two groups (group A and group B) according to the internal fixation type. The patients of group A (n=50) underwent with minimally transforaminal lumbar interbody fusion (TLIF) and unilateral pedicle screw fixation with one single cage placement assisted by Quadrant system;and the patients of group B (n = 52) underwent with posterior lumbar interbody fusion (PLIF) and bilateral pedicle screw fixation with one single cage placement. There were no significant differences between two groups in general information (P > 0.05). VAS score and ODI score system were used to evaluate the preoperative and postoperative pain and function recovery. Operative time, volume of blood loss, fusion rate and complication rate were compared and analyzed by statistical test.

RESULTSAll the patients were followed up from 12 to 21 months with an average of 18.2 months. In the group A,operative time and volume of blood loss were (87.6 +/- 25.5) min and (105.7 +/- 27.2) ml, respectively; VAS score of low back pain and leg pain, ODI score decreased respectively from preoperative 7.2 +/- 1.4, 7.9 +/- 1.1, 42.2 +/- 11.8 to 3.2 +/- 0.6, 3.0 +/- 0.7,15.6 +/- 2.3 at one month after operation; the fusion rate was 96.0% (48/50) and the complication rate was 4.00% (2/50). In the group B,operative time and volume of blood loss were (160.3 +/- 20.5) min and (220.6 +/- 25.5) ml, respectively; VAS score of low back pain and leg pain, ODI score decreased respectively from preoperative 7.3 +/- 1.1, 8.1 +/- 0.9, 43.1 +/- 12.0 to 3.3 +/- 0.4, 3.2 +/- 0.3, 14.9 +/- 2.6; the fusion rate was 96.2% (50/52) and the compli- cation rate was 5.77% (3/52). There were no statistically significant differences between the two groups in fusion rate, complication rate, VAS pain and ODI score. Whereas the operative time and blood loss in group A were significantly lower than that of group B.

CONCLUSIONMinimally invasive unilateral pedicle screw fixation is a safe and feasible method for the treatment of lumbar degenerative diseases. It is as effective as the bilateral fixation in lumbar spinal fusion. In addition, it has the advantages of short operative time, less volume of blood loss, high fusion rate, etc.

OBJECTIVETo explore the effect of acupoint massage dominant early comprehensive intervention on the prognosis of premature infants with brain injury.

METHODSTotally 210 premature infants with brain injury were assigned to the intervention group (112 cases) and the control group (98 cases). All patients received routine therapy (medicinal + routine care instructions). Patients in the intervention group additionally received acupoint massage. Those with abnormal early motion received physical sports treatment. Those with upper limbs dysfunction or with fine movement disorders received occupational therapy. Premature infants' development quotient (DQ) was performed at corrected age of 6 and 12 months by using neuropsychological development examination table for 0 - 6 years old children. The incidence of cerebral palsy was statistically calculated.

RESULTSAt corrected age of 6 months, DQ of gross motor, fine motor, language three functional areas was higher in the intervention group than in the control group with significant difference (P < 0.05). At corrected age of 12 months, DQ of gross motor, fine motor, language, social and adaptive capacities was higher in the intervention group than in the control groupwith significant difference (P < 0.05). The incidence of cerebral palsy was 4.46% (5/112) in the intervention group and 12.24% (12/98) in the control group (P < 0.05).

CONCLUSIONAcupoint massage dominant early comprehensive intervention could obviously improve the intelligence development level and lower the incidence of cerebral palsy in premature infants with brain injury.

Objective:To study the effect of curcumin on enterocyte apoptosis and its protective effect on intestinal mucosal barrier in septic rats.Methods:Eighty-seven 3-month male Sprague-Dawley (SD) rats were divided into Sham group, model group and curcumin group by random number table method, with 29 rats in each group. The septic rat model was reproduced by cecal ligation and puncture (CLP). 4 mL dimethyl sulfoxide solution were intraperitoneally injected in both Sham group and model group, 200 mg/kg curcumin dissolved by 4 mL dimethyl sulfoxide solution were intraperitoneally injected in curcumin group 10 minutes after operation. The blood samples (15 rats in each group) were collected 2, 12, 24 hours after operation, and the levels of serum procalcitonin (PCT), tumor necrosis factor-α(TNF-α), D-lactic acid and diamine oxidas (DAO) were tested by enzyme linked immunosorbent assay (ELISA). The ileum tissues were collected 12 hours, 24 hours after operation in three groups, water content was tested by weighting, pathologic structure was observed by light microscope, the enterocyte apoptosis was tested by terminal deoxynucleotidyl transferase-mediated dUTP-nick end labeling method (TUNEL). The 7-day survival rate was observed in three groups (14 rats in each group).Results:The serum levels of PCT, TNF-α, D-lactic acid and DAO were higher in model group at 2, 12, 24 hours after operation than those in Sham group, PCT, TNF-α levels were significantly higher in model group than those in Sham group 2 hours after operation [PCT (μg/L): 1.89±0.17 vs. 0.10±0.02, TNF-α (ng/L): 216.51±1.47 vs. 85.25±8.20, both P < 0.01], D-lactic acid, DAO levels were significantly higher in model group than those in Sham group 12 hours after operation [D-lactic acid (mg/L): 40.53±7.76 vs. 11.29±1.28, DAO (ng/L): 1 120.40±302.35 vs. 330.02±81.28, both P < 0.01]. Compared with model group, the levels of serum PCT, TNF-α, D-lactic acid and DAO were lower in curcumin group 2, 12, 24 hours after operation, the statistical difference appeared from 12 hours after operation [PCT (μg/L): 5.37±0.44 vs. 8.67±0.64, TNF-α(ng/L): 211.12±4.31 vs. 313.30±18.46, D-lactic acid (mg/L): 29.74±1.41 vs. 40.53±7.76, DAO (ng/L): 810.71±201.41 vs. 1 120.40±302.35, all P < 0.05], curcumin group had lower water content in ileum tissues 12 hours, 24 hours after operation [(68.34±0.68)% vs. (70.55±0.87)%, (69.41±0.59)% vs. (71.69±0.87)%, both P < 0.05]. The pathologic structures of intestinal villus were normal in Sham group, however, in model group intestinal villus were atrophic, edematous and shorten 12 hours after operation, it was further exacerbated 24 hours after operation. Compared with model group, the pathologic structures of intestinal villus in curcumin group were relived 12 hours, 24 hours after operation. The number of apoptotic enterocytes were significantly increased in model group compared with Sham group 24 hours after operation (cells: 25.48±6.10 vs. 4.00±2.04, P < 0.05), and the number of apoptotic enterocytes was lower in curcumin group than that in model group at the same time (cells: 15.48±3.75 vs. 25.48±6.10), the difference was statistically significant (both P < 0.05). Seven-day survival rate was significantly lower in curcumin than that in model group [42.9% (6/14) vs. 50.0% (7/14)], however, the difference was not statistically significant ( P > 0.05). Conclusion:Curcumin can protect the intestinal mucosal barrier by inhibiting enterocyte apoptosis in septic rats.

Objective To understand the prevailing status of coal-burning endemic fluorosis in Henan, and to provide scientific grounds for endemic fluorosis prevention. Methods Undertook general surveillance on factors such as coal using, living habit, main foods, the structure of the houses and the fluoride content in drinking-water among 1832 historical coal-burning endemic fluorosis villages within 13 counties in 2006 and 2007, and conducted focal point sampling survey on 216 villages which still using local high-fluoride. For all children aged 8-12 years of each village, conducted dental fluorosis examination and collected 30 immediate urinary samples for fluoride content determination. Results The fluoride content in drinking-water of all historical fluorosis villages was below 1.0 mg/L. Households having individual kitchens accounted for 93.7%(241 281/257 393), those with stoves having smoke evacuation devices accounted for 41.9% (107 917/257 393), those using local high-fluoride coal for cooking accounted for 28.6%(73 686/257 393), those using local high-fluoride coal for heating accounted for 24.1%(61 924/257 393). Villages with serf-supply of main foods accounted for 95.7%(1753/1832) of all fluorosis villages. Solar drying food was used in all households. Villages with dental fluorosis detection rate for children aged 8 to 12 years above 30.0% accounted for 16.2%(35/216), which axe all in Luoyang City. Among 77.8%(168/216) of fluorosis villages, children' s urinary fluoride concentrations were no higher than 1.50 mg/L. Conclusions Coal-burning endemic fluorosis areas in Henan Province were decreased greatly and the extent of the health hazard was becoming slightly. The detection rate of dental fluorosis for children aged 8 to 12 years of 8 counties had reached the standard for fluorosis control, whereas the other 5 counties had not yet, all located in Luoyang City.

To explore the cytogenetics and related clinical characteristics of adult acute leukemia with Philadelphia chromosome positive (Ph(+)AL), MIC classification by morphology, immunology and cytogenetics was used to retrospectively study 79 patients with Ph(+)AL hospitalized in the Institute of Hematology, People Hospital in Beijing from October 1991 to September 2003. The results showed that 6.9% cases were diagnosed as Ph(+)AL and classified into three subtypes: acute lymphoblastic leukemia (Ph(+)ALL) in 56 patients (18%), acute myeloid leukemia (Ph(+)AML) in 10 patients (1.2%) and mixed acute leukemia (Ph(+)MAL) in 13 patients. B-cell antigen expression was found in 52 out of 56 patients with Ph(+)ALL. 54.4% (43/79) patients had additional chromosome abnormalities including chromosome 7, double Ph and plus 8, etc. Complete remission (CR) rate of Ph(+)ALL and Ph(+)MAL was 57.0%, none of Ph(+)AML achieved CR. Median overall survival of Ph(+)ALL, Ph(+)MAL and Ph(+)AML were 10, 10 and 2.5 months respectively. It is concluded that Ph(+)AL has highly heterogeneity involving various differentiated stages of immature leukemic cells. Since the poor prognosis associated with this kind of AL, early diagnosis with MIC classification is a prerequisite to take more effective conditioning regimen and prospectively consideration of allogeneic stem cell transplantation to improve prognosis.

BACKGROUND/AIMS: Early colorectal (CR) neoplasm can be cured by endoscopic submucosal dissection (ESD), but clinical experience and factors associated with complications from ESD for CR neoplasms in China have not been reported. METHODS: Seventy-eight cases of early CR neoplasm treated with endoscopic resection performed between December 2012 and December 2013 at Beijing Military General Hospital were included. Factors associated with ESD complications and procedure times were evaluated. RESULTS: The en bloc resection rate was 88.5% (69/78), tumor size was 32.1+/-10.7 mm, and procedure time was 71.8+/-49.5 minutes. The major complication was perforation, which occurred in 8.97% of the ESD procedures. Multivariate logistic regression analysis indicated that only tumor size (p=0.022) was associated with ESD perforation. Tumor size (p<0.001) and the non-lifting sign (p=0.017) were independent factors for procedure time, and procedure time (p=0.016) was a key factor for en bloc resection. After a median 10 months (range, 4 to 16) of follow-up, no patients had local recurrence. CONCLUSIONS: This study indicated that ESD is an applicable method for large early CR neoplasm in the colon and rectum. Tumor size and the non-lifting sign might be considerable factors for increased complication rate and procedural time of ESD.
