Objectives To search for the relationship between HP and lesions of gastric mucosa of children.Methods Four hundred and fifty-eight bioptic specimens-from eastrie mueosa in children were strained with hematoxylin-eosin(HE)and Warthin-Starry for light microscopic study.Results HP was detected in 152 specimens. HP deteetable rate-in specimens with normal mucosa was 1. 1%, in compari-on with 42.3% in those with chronic superficial gastritis and 14. 3% in those with chronic atrophic gastrins .Specimens with chronic active gastritls, mostry manitesting local active lesions,had HP detectable rate of as high as 80.2%、69. 7% of the specimene with HP were found to have obvious lymph follicles reaction within lamina propria in their gastric mucosa.Conclusions There is a close relationship between HP infection and Pediatric chronic gastritis(especially chronic active gastritis). Histopathologically, HP-associated gastritis is characterized by chronic and local active inflamations, and tbe formation of lymph follicles within lamina propria.

OBJECTIVETo observe the clinical efficacy difference on vegetative state in children between acupoint injection combined with plum-blossom needle and western medication based on basic treatment.

METHODSForty-eight children of vegetative state were randomized into an observation group and a control group, 24 cases in each one. On the basis of the treatment of transcranial magnetic stimulation apparatus, balancing treatment apparatus and massage, the acupoint injection and tapping method with plum-blossom needle were adopted in the observation group, in which Xingnaojing injection, mouse nerve growth factor (mNGF) injection, monosialotetrahexosylganglioside sodium injection (MSI), compound Danshen injection were divided in 6 pairs and were injected respectively in Baihui (GV 20), Yongquan (KI 1), Fengfu (GV 16), Yamen (GV 15) and the others, 0.5 mL in each acupoint, once a day for continuous 10 days. Additionally, the tapping method with plum-blossom needle was used on the Governor Vessel and Jiaji (EX-B 2) on the back. In the control group, the intravenous infusion was adopted with citicoline sodium injection, mannitol injection and dexamethasone injection. The treatment was given once a day, 20 days of treatment made one session and totally 3 sessions were required in the two groups. The clinical efficacy, the vegetative state score and the mean curing time were observed after 20 days, 40 days and 60 days of treatment between the two groups.

RESULTSThe effective rates were 58.3% (14/24), 70.8% (17/24) and 79.2% (19/24) in 20 days, 40 days and 60 days of treatment in the observation group and 20.8% (5/24), 45.8% (11/24) and 58.3% (14/24) in the control group respectively. The efficacy in the observation group was superior to those in the control group (P < 0.01, P < 0.05). The vegetative state score was improved apparently after 20 days, 40 days and 60 days of treatment as compared with those before treatment separately (all P < 0.05). It was improved obviously at the each time point after treatment in the observation group as compared with that in the control group (3.34 +/- 2.41 vs 2.64 +/- 11.56, 6.20 +/- 1.46 vs 4.34 +/- 1.64, 11.26 +/- 2.63 vs 8.75 +/- 2.18, all P < 0.05). The mean curing time was (45.67 +/- 16.24) days in the observation group, which was shorter apparently than that of (55.34 +/- 4.57) days in the control group (P < 0.05).

CONCLUSIONBased on basic treatment acupoint injection combined with tapping method of plum-blossom needle achieve the reliable efficacy on vegetative state in children.

ObjectiveTo evaluate the applicability of modified formulas based on plasma creatinine levels in Chinese patients with chronic kidney disease (CKD). MethodsA total of 327 CKD patients were investigated. Glomerular filtration rate (GFR) was estimated with Chinese equations and Ruijin equation. The accuracy of estimated GFR was compared with 99mTc-DTPA-GFR (sGFR) in CKD patients. ResultsBland-Ahman analysis demonstrated that Ruijin equation was more consistent with sGFR than the other equations. But all the equations were not well consistent with sGFR. Linear regression showed that the slopes of Ruijin equation and MDRD-1 equation were closer to the identical line. 15%, 30% and 50% accuracy of Ruijin equation were higher than the other equations. But 30% accuracy of Ruijin equation was still less than 70%. When the accuracy of estimated GFRs was compared with sGFR in different stages of CKD, GFR estimated by Ruijin equation showed good results. ConclusionsWhen plasma creatinine is checked with enzymatic method, modified GFR estimation equations may show great bias in Chinese CKD patients. More clinical trails should be carried out to evaluate and identify the application of modified GFR estimation equations in Chinese patients with CKD.

Objective To explore the prenatal genetic diagnosis for classic phenylketonuria (PKU) families.Methods Probands and their family members from three classic PKU families were analyzed by combining linkage analysis through short tandem repeats (STR) polymorphism and PCR-sequencing for the exons within mutation hot spot of phenylalanine hydroxylase gene.Results Linkage analysis found uninformative for Family 1,while 100 % confirmative information was obtained from Family 2 and 3.Sequencing showed compound heterozygous mutations of phenylalanine hydroxylase gene for all of the three probands.Five mutations were detected,namely Y166X,R243Q,R413P,EX6-96A ＞ G and IVS11-1G＞ C,and IVS11-1G ＞ C was a novel identified muntation.Information from linkage analysis and mutation screening showed clearly that the fetus of Family 1 and 2 were affected,while normal for Family 3.Conclusions For those PKU families,reliable service of prenatal genetic diagnosis could be provided by combining linkage analysis with mutation screening of phenylalanine hydroxylase gene.

AIM: To determine the association between subfoveal choroidal thickness before therapy and therapeutic activity in diabetic macular edema.
METHODS: The current study was a retrospective study, which included 32 patients ( 32 eyes ) diagnosed with diabetic retinopathy and macular edema. All the patients were firstly treated with intravitreal injections of ranibizumab. Main outcome measures were included the subfoveal choroidal thickness, central macular thickness and best-corrected visual acuity ( BCVA) at preoperation and postoperative visit at 3mo.
RESULTS: After 3 monthly intravitreal injections of ranibizumab, the BCVA was significantly higher than that before therapy and accompanied with significantly reduced thickness of subfoveal choroid and central fovea of macula. Spearman analysis was revealed that a greater baseline subfoveal choroidal thickness was associated with a better BCVA (rs=0. 544, P=0. 036).
CONCLUSION:In the therapy of intravitreal injections of ranibizumab on diabetic macular edema, there seems to be a better BCVA in the patients with a greater baseline subfoveal choroidal thickness. Therefore, baseline subfoveal choroidal thickness may be a useful predictor for the therapy of diabetic macular edema.

Objective To detect the expression and function of cysteinyl leukotriene receptors (CysLTRs)in keratinocytes.Methods Human keratinocytes were isolated from the tissue of foreskin by digestion with dispase Ⅱ and trypsin,and subjected to primary culture.By using confocal laser scanning microscopy and reverse transcriptase PCR,the localization and expression of CysLTRs were studied in kemtinocytes.respectively.Some primarily cultured keratinocytes were pretreated with leukotriene D4 (30 nmoi/L),MK571(300 nmol/L),and BAYu9773 for 5 minutes followed by the detection of intmcellular calcium level using the Ca2+ indicator dye Fura-2/AM as well as cell proliferation bv MTT assay.Results The expressions of CysLTR1 and CysLTR2 were observed in cultured keratinocytes,and they were mainly located on cell membrane,partly in cytoplasm and nuclei.Compared with non.stimulated cells,a significant increase Was noted in the expression of CysLTRs,especially in the nuclei of keratinocytes stimulated by LTD4(P＜0.05),together with an elevation in intracellular calcium level(42.27±3.00 mmol/L,P＜0.01)and acceleration in cell proliferation (P＜0.01).However,both MK571 and BAYu9773 could completely block the effect of LTD4 on intmcellular calcium level and cell proliferation.and there was no significant difference in the blocking effect between MK571 and BAYu9773.Conclusions Functional CysLTRs are expressed in human keratinocytes.and they carl increase the intracellular calcium level in,and cell proliferation of,keratinocytes.

Objective To investigate the expression of periostin in the kidneys of rats with obstructive nephropathy and its relevance to renal interstitial fibrosis.Methods Eighteen male adult SD rats were randomly divided into sham group,model group and benazepril group (6 in each group).Unilateral ureteral obstruction (UUO) model was induced by ligating the left ureter of rats.RT-PCR was used to detect the mRNA expressions of periostin and TGF-β1,and ELISA to detect the protein expression of periostin,Ang Ⅱ,and TGF-β1 in kidney tissue.Pathological changes of renal tissue were observed by HE and Masson staining.The protein expression of collagen Ⅰ (Col Ⅰ ) in kidney tissue was examined by immunohistochemical staining.Results The mRNA expressions of periostin and TGF-β1 in model group increased markedly as compared with sham group (all P＜0.05),and benazepril could decrease these mRNA expressions (all P＜0.05).The protein expressions of periostin,Ang Ⅱ and TGF-β1 in kidney tissue were significantly increased in model group as compared with sham group (all P＜0.05),and benazepril could decrease these protein expressions (all P＜0.05).The expression of periostin in kidney tissue was positively correlated with the expressions of Ang Ⅱ,TGF-β1 and Col Ⅰ,as well as the degree of renal interstitial fibrosis (r=0.652,0.781,0.776 and 0.825 respectively,all P ＜0.05).Conclusion Periostin expression is up-regulated in kidney tissue of rats with obstructive nephropathy,which is associated to the over-deposition of extracellular matrix (ECM) in the kidneys of UUO rats.

Objective To compare the effects of fluvastatin and valsartan on the inflammatory cytokines in the early stage of type 2 diabetic nephropathy and their protective effects on to diabetic nephropathy. Methods Ninety patients with early stage of type 2 diabetic nephropathy were divided into three groups, 30 patients receiving routine hypoglycemic agents (DN1) as control,30 patients receiving routine hypoglycemic agents plus valsartan (DN2) and the other 30 receiving routine hypoglycemic agents plus fluvastatin (DN3). Blood glucose, blood lipid,serum creatinine and C reactive protein(CRP),24-hour urine protein,urinary albumin excretion rate (UAER) and several inflammatory cytokine were measured before and after treatment. Results ( 1 ) No significant difference of the levels of serum CRP,TGF-β1,IL-6,TNF-α, IL-18 at the baseline were observedamong these three groups.In the DN2 group,after treatment,IL.6 was([15.99±2.87]ng/L and[17.64±2. 131 ,P <0. 05) ,TGF-β1 was ( [33.54 ±10. 69] μg/L and [40. 11 ± 12. 08] μg/L,t = -2. 921 ,P <0. 01 ),IL-18 was ( [139.65±66. 37] ng/L and [158.74±74. 20]ng/L,t = -2.053,P <0. 05),CRP was ( [5. 12±3. 54] mg/L and [6. 08 ±3. 39] mg/L, t = - 2. 072, P < 0. 05 ) after and before treatment, respectively. All abovemented indices significantly decreased after treatment. In the DN3 group, IL-6 was ( [15. 39 ±2. 77] ng/L ng/L,t = -3. 651 ,P <0. 01 ) ,TGF-β1 was ( [31.19 ±10. 48] μg/L and [37. 11± 11.76] μg/L,t = -2. 963,P<0.01),IL-18 was ([141.54 ±66.65] ng/L and [158.01±73.23] ng/L,t = -2. 182,P <0.05),CRP respectively. All abovemented indices significantly decreased after treatment No significant difference was observed on inflamaory factors after treatment between the DN2 and DN3 group ( P > 0. 05). (2) In the subgroup that there was no difference in blood pressure between before and after treatment in both the DN2 and DN3 group,in the DN3 group,UAER was ([63. 1 ±31.7] μg/min and[82.9±40.0] μg/min,t = -2. 145,P <0. 05) ,24 h total urokinase protein was ( [0. 14 ±0. 11] g/24 h and [0. 18±O. 15] g/24 h, t = - 2. 438, P <0. 05 ), microalbuminuria/urine creatinine was ( [ALb/Cr] [114. 7±68. 1] mg/g and [162.0±83.8] mg/g,t = - 2. 399, P < 0. 05 ) after and before treatment. All abovemention indices significantly decreased after treatment. In the DN3 group, UAER was ( [65.5 ±32. 6]μg/min and [83.5 ±42. 1]μg/min,t = - 2. 131, P <0. 05 ),24 h total urine protein was ( [0. 14 ±0. 11] g/24 h and [0. 18±0. 15] g/24 h, t = - 2. 438, P < 0. 05 ),0. 05 ) after and before treatment. All abovemention indices significantly decreased after treatment. No significant difference was observed after treatment between the DN2 and ON3 group ( P > 0. 05 ). Conclusion Both valsartan and fluvastatin are able to protect the renal function of patients with type 2 diabetic nephropathy by decreasing the levels of urine proteins and correlated serum inflammatory cytokines.
