Objective To study the relationship between helicobocter pylori(Hp)infection and iron deficiency anemia(IDA)in children.Methods Children who had upper digestive symptom were had gastroscopy examination and Hp test.According to the examination results,all the patients were divi-ded into 2 groups,the observation group and the control group.All patients were detected blood routine,serum iron(SI),serum ftrritin(SF)and total iron-binding capacity(TIBC).Results The IDA morbidity was 52.27%(23/44 cases)in obsorvation group and 17.39%(8/46 cases)in control group,there was obvious difference between two groups(?2=12.12 P

Objective To evaluate of red blood cell as giving instruction in whole white blood cell immunological activity by new nature experimental system of hemaimmune reaction rood map. Methods Plasma 0.3ml were added to whole blood cells (including: red blood cell and white blood cells) or white blood cells 0.2ml, and incubated for 1h at 37℃. The content of IL-8 and IL-12 was determined by enzyme linked immunadsorbent assay (ELISA) method. The expression level of CD4, CD8, CD35 and CXCR4 on white blood cells was determined by method of Flow Cytometry. Results The content of IL-8 (5.96?4.26) and IL-12 (9.84?2.23) in whole blood and plasma nature group was significantly lower than that (13.59?3.69?B?pg~ -1 ?ml~ -1 ) and (15.09?9.86?B?pg~ -1 ?ml~ -1 ) in white blood cell and plasma isolation group (P

[Objective]To compare the fixation effects of cannulated compression screws and dynamic hip screws.[Method]From July 2000 to December 2006,152 old patients with intertrochanteric hip fracture were fixed with cannulated compression screws(n=68) and dynamic hip screws(n=84).They were followed up and their complete clinic data were obtained.A retrospective comparison was made between the two differet fixation devices in terms of operation time,blood loss,intraoperative and postoperative complications,functional recovery one year postoperatively and treatment expenses.[Result]The differences in operation time,blood loss between 2 groups had statistical significance(P0.05) for the Evans types Ⅰ,Ⅱ patients,but had statistical significance(P

Objective To discuss the clinical significance of the diffuse calcified distribution in diagnosis of benign and malignant breast lesions .Methods 379 patients with different benign and malignant breast lesions confirmed by surgery underwent digital X‐ray mammography .The morphology ,distribution ,number ,diameter ,concentration and density of calcification in lesions ,the maximum range of the calcified area and other accompanied manifestations in benign and malignant breast lesions were analyzed .Results As for the morphology of calcification ,tiny polymorphic calcification was found in 58 .5% of malignant lesions ,meanwhile ,dot‐like one was found in 49 .3% of benign lesions .Fine linear calcification or branched linear one occurred in malignant lesions ,however ,round one occurred in benign lesions .As for the calcification distribution ,regional distribution was found in 43 .9% of malignant lesions , meanwhile the clustered distribution was found in 58 .4% of benign lesions .And all lobar or segmental distribution was seen in malig‐nant lesions .As for the calcification diameter ,the calcification with the diameter less than 0 .5 mm occurred in 71 .6% of malignant lesions ,however ,that with diameter more than 1 .0 cm occurred in 69 .3% of benign lesions .As for the concentration of calcification , lesions with calcification more than 25 were 71 .8% of malignant ones ,whereas those with calcification of 15-25 were 58 .4% of be‐nign ones .As for calcified density ,uneven calcification occurred in 94 .2% of malignant lesions ;however the even one occurred in 63 .4% of benign lesions .The maximum diameter of calcification ranged from 40 mm to 80 mm was found in 59 .0% of malignant lesions , whereas that ranged from 0 mm to 40 mm was in 77 .2% of benign lesions .Conclusion Statistical differences have been found in the morphology ,distribution ,diameter ,concentration ,density and maximum diameter of calcification between the breast benign and ma‐lignant lesions .

The morbidity of diabetes has been increasing rapidly in recent years. Delayed wound healing has become a common complication in diabetes, which seriously affects the orthobiosis of patients. Exploring and finding the molecular mechanisms of diabetic wound healing and the effective therapies to promote wound healing have important clinical significances. Stem cells transplant has become a research hotspot in accelerating diabetic wound healing. This article reviewed the present approaches concerning stem cells transplant in diabetic wound healing both at domestic and abroad, and looked forward the clinical therapy of stem cells on diabetic wound healing.

Objective To observe the effect of gene gun transduction of K-RAS Antisense gene on the expression of K-RAS P21 protein in human pancreatic carcinoma cells.Methods K-RAS Antisense gene was transduced into pancreatic carcinoma cells by gene gun transduction, the expression of K-RAS P21 protein on BxPC-3、AsPC-1 and MiaPaCa-2 pancreatic carcinoma cells line were examined by western blot and immunocytochemistry staining. Results The expression of K-RAS P21 protein in AsPC-1 and MiaPaCa-2 pancreatic carcinoma cells was obviously lower after the transduction of specific K-RAS Antisense gene,which has little impact on BxPC-3 pancreatic carcinoma cells. Conclusion Gene gun transduction of K-RAS Antisense gene is a potential method for treatment of pancreatic carcinoma.

myocytes.In aging mice induced by D-galactose experiment.TP has anti-apoptosis and anti-oxidation effect in a dose-dependant manner.

ObjectiveTo explore the role of autofluorescence bronchoscopy in lung cancer operation and the meaning of choice lung cancer operation mode.MethodsTo retrospectively analyze 32 non-small cell lung cancer patients.Before lung cancer operation,white light bronchoscopy (WLB) and autofluorescence bronchoscopy (AFB) had been done routinely.Compared the different invasive tumor conditions by WLB and AFB,operation modes were decided by the edge of the tumor which were proved by biopsy pathology.ResultsIn 32 cases,19 cases underwent pulmonary lobectomy.One case underwent carinal resection and reconstruction.8 cases underwent sleeve lobectomy.4 cases underwent other therapy because of tumor airway metastasis.In 8 cases which underwent sleeve lobectomy,3 ca ses were found by WLB and AFB together,5 cases were found only by AFB.In 4 cases who had no operation chance,2 cases were found by WLB and AFB together,2 cases were only by AFB.The sensitivity for the detection of bronchial premalignant lesions was extremelyhigher withthe addition of AFB than WLBalone ( P ＜ 0.05 ).ConclusionAutofluorescence bronchoscopy is a safe and efficient technique which could improve the sensitivity of diagnosis in lung cancer than WLB.It is important to select operation mode.

Objective To analyze prognostic factors in children with acute myeloid leukemia(AML).Methods Retrospective analyze the relationship between many factors of the diagnosed children with AML and their 3-years event-free survival(EFS).Statistics was analyzed with ?2 test.Results The 3-years EFS was 47.5%.According to the analysis of statistics,EFS of some children groups had statistical differences with their controls (P

Objective To explore the property and diagnostic significancec of transnasal gastroscope(EG-470N5)in children with upper gastrointestinal tract disorders.Methods Sixty children with upper gastrointestinal tract disorders were examined by using EG-470N5.The scope was inserted either through nose(n=28)or via mouth(n=32).Beside the routine preparations,nasal spray of lidocaine or nasal drib of ephedrine was added to those who received nasal intubation.Results Examination of upper gastrointestinal tract subjects in all succed with no obvious side response in 28 cases(46.7%)who received the examination via nose,27 cases(45%)had mild nausea and 5 cases(8.3%)had serious nausea and dysphoria.Children with esophagostenosis and pyloristenosis and 2-day-old neonate were examined without adverse effect.Conclusions Transnasal gastroscope is preponderant to children due to its slim diameter and supple body,especially to those having swallow difficulty and confined tract.It is more favorable practical prospect than routine gastroscope.
