Objective To investigate the relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents;To provide basis for the targeted interventions for couples of childbearing age before pregnancy-periconceptional TCM constitution. Methods Compiling scales for pregnant couple’ TCM constitution type assessment and postpartum visits to newborns, the research team got access to the information of neonatal physical problems, constitutions and changes of 675 babies’ father and mother who had established maternal manual from April, 2012 to March, 2013 at the Sanlin Community Health Center of Pudong District of Shanghai. Results Early to mid-pregnancy expectant parents mainly had peace constitution type. In detail, 55% of pregnant women had gentle constitution type, while others mainly had qi deficiency, yang deficiency and damp-heat constitution types;76% expectant fathers got peace constitution, while others mainly got damp-heat, yin deficiency and qi deficiency constitution types. Marital pregnancy physique did not change significantly. Compared with the peace constitution type, newborns, whose fathers got damp-heat constitution type, had higher risk of jaundice, and whose mothers got yin deficiency, the babies had higher risk of spits (P<0.05). The constitution types of expectant parents did not have obvious combined action on neonatal health. Conclusion There is a certain relationship between neonatal health and TCM constitution types of early to mid-pregnancy expectant parents. It is necessary to distinguish constitution types of prospective parents, and thus to take targeted health interventions.

Objective To investigate the role of IgG determination in diagnosis of early renal damage in children with Henoch-schonlein purpura(HSP). Methods Urine IgG was determined in 188 children with HSP (HSP group), 99 patients with Henoch-schonlein purpura nephritis (HSPN group) and 26 healthy controls (healthy control group). Simultaneously, qualitative detection of urine protein was carried out in HSP group. Results The abnormality rate of urine IgG was significantly higher than that of urine protein in HSP group (P<0. 05). The level of urine IgG was significantly higher in HSP group than that in healthy control group (P<0. 05), while the level of urine IgG in group than that in HSP group (P<0. 05). Conclusion Urine IgG determination is simple and nonin-vasive, which if high clinical value in diagnosis of early renal damage in children with Henoch-schonlein purpura(HSP).

Objective To study the effect of IL-8 on cell proliferation and invasion,and to analyze the correlations between chemokine and epidermal growth factor receptor(EGFR)signaling pathways in breast carcinoma cells.Methods IL-8 secretion responded to treatment with rhEGF and anti-EGFR and expression of its receptors CXCR1,CXCR2 in MDA-231 cells were measured by ELISA and immunocytochemistry,respectively.Effect of rhIL-8 and neutralizing antibody on cell proliferation and invasion were analyzed by using MTT and matrigel invasion assay.EGFR transactivation stimulated with rhIL-8 and neutralizing an tibody was assessed by Western blot using anti-phosphotyrosine antibody.Results MDA-231 cells released hish level of IL-8 and two receptom of IL-8(CXCR1 and CXCR2)both expressed on cell membrane.Exogenous IL-8 and its neutralizing antibody did not significantly influence the proliferation of breast carcinoma cells,but rhIL-8 stimulated invasive activity in MDA-231 cells and its neutralizing antibody inhibited the in vasive activity(P＜0.05).EGF and anti-EGFR both inhibited the secretion of IL-8 in breast carcinoma cells,and IL-8 had no effect on EGFR phosphorylation,but anti-IL-8 induced transactivation of EGFR after 24h.Conclusion IL-8 contributes to tumor progression in breast carcinoma through its enhancement of in vasive activitv but not act as an autocrine growth factor.The correlation of competitive inhibition rather than cross-talk is found between G protein coupled receptor(GPCR)-mediated IL-8 signaling pathway and EGFR pathway in breast carcinoma.

Objective:To explore the expression of IL-5 and its role in the formation and development ofnasal polyp. Method: 31 patients with nasal polyp, 11 patients with chronic sinusitis (CS) and 6 control cases werechosen . Their IL-5 concentration in tissue homogenate were measured by ELISA. All patients with chronic si-nusitis,control cases and 15 patients with nasal polyp were chosen to be counted eosinophils in their HE slice.Result :①The values of IL-5(pg/ml) in nasal polyp,CS and control group separately were .. 23.44± 6.68,16.41±3.09,12.86±4.17. IL-5 concentration in nasal polyp group was higher than that in the other two groups( P ＜0. 001). ②The numbers of eosinophils in nasal polyp ,CS and control group were 7.42±2.33,1.30± 0. 59,1.07±0.70 separately,the numbers of eosinophils in nasal polyp group were higher than that in CR or control group(P ＜ 0.05). Conclusion: Nasal polyp is a disease characterized by eosinophilia, and IL-5 which activateseosinophil plays part role in the formation of nasal polyp.

Objective: To explore the IL\|5 values in the tissue and secretion of nasal polyp. Methods: The concentrations of IL\|5, either in tissue homogenate or in nasal secretion, were measured by ELISA. The values of total protein in tissue homogenate were measured by Bradford colorimetry. In this study, 31 cases with nasal polyp, 8 patients with perennial allergic rhinitis (PAR), 11 cases with chronic sinusitis (CS) and 6 control cases were chosen. Results: ① In tissue homogenate, the IL\|5 concentrations of nasal polyp were higher than that in CS or control group (P＜0.001). ② In nasal secretion, IL\|5 values of both nasal polyp and PAR group were significantly higher than that in CS or control group (P＜0.05). ③ When all cases or only patients with nasal polyp were taken as the subjects, the Pearson correlation coefficient were 0.70, 0.66 respectively. Conclusions: IL\|5 values, both in tissue homogenate and nasal secretion, are significantly higher, which suggested that there were a close relationship between IL\|5 and nasal polyp, and IL\|5 play a key role in the formation of nasal polyp.

AIM: To study the effect of the overexpression of p16 on an anion exchange function of band 3 in HeLa cells. METHODS: The expression of p16 and band 3 in HeLa cells was detected by immunohistochemistry (IHC). The p16 cDNA was subcloned to plasmids pEGFP-C1 by PCR and identified by restriction enzyme digestion and sequencing, and then, the recombinant pEGFP-C1-p16 plasmids were transiently transfected into HeLa cells. The expression of fusion protein in HeLa cells was detected by fluorescence microscope. 6-methoxy-N-(3-sulfopropyl)-quinolinium(SPQ)fluorescent probes were used to detect the anion exchange function of band 3. RESULTS: P16 and band 3 were expressed in HeLa cells. The amplificated p16 cDNA sequence was the same as the report sequence. The transfective efficacy of pEGFP-C1-p16 was above 60%. The anion exchange function increased after the transfection of pEGFP-C1-p16 plasmids. CONCLUSION: p16 facilitates the anion exchange function of band 3 in HeLa cells.

Objective To compare the efficacy and safety of full-thickness peroral endoscopic myotomy (POEM) and circular myotomy for patients with severe achalasia.Methods The clinical data of 123 patients with severe achalasia who were admitted to the Second Xiangya Hospital of Central South University from August 2011 to May 2013 were retrospectively analyzed.Seventy patients who received full-thickness POEM were in the full-thickness myotomy group,and the other 53 patieuts who received circular myotomy were in the circular myotomy group.The clinical efficacies and incidences of complications of the 2 groups were compared.Patients in the 2 groups were followed up at the out-patient department till May 2014.The consecutive measurement data were presented by (x) ± s and analyzed using thc t test; the non-consecutive data were presented by M (range) and analyzed using the Wilcoxon rank test.Data before and after operation were compared using the repeated measure of analysis of variance.The count data were analyzed using the chi-square test.Results All the patients successfully received POEM.The operation time of the full-thickness myotomy group and the circular myotomy group were (57 ± 8)minutes and (63 ± 12)minutes,with significant difference between the 2 groups (t =3.421,P ＜0.05).The incidences of complications of the full-thickness myotomy group and the circular myotomy group were 14.3％ (10/70) and 11.3％ (6/53),with no significant difference between the 2 groups (x2=0.234,P ＞0.05).Atotal of 119 patients were followed up,with the median time of 18 months (range,12-24 months).The Eckardt scores at postoperative month 6 and 12 were 0 (range,0-3) and 0 (range,0-3) in the full-thickness myotomy group,and 0 (range,0-2) and 0 (range,0-3) in the circular myotomy group,with no significant difference between the 2 groups (Z =0.525,1.476,P ＞ 0.05).The sussess rates of the full-thickness myotomy group and the circular myotomy group were 98.6％ (69/70) and 98.1％ (52/53),with no significant difference between the 2 groups (x2=0.040,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 of the full-thickness myotomy group and the circular myotomy group were (3.2 ± 0.3) cm and (3.4 ± 0.4) cm,with no significant difference between the 2 groups (t =1.927,P ＞ 0.05).The diameters of the esophagus at postoperative month 6 and 12 were significantly lesser than (5.9 ± 1.0) cm and (5.9 ± 1.0) cm before operation (F =780.923,493.018,P ＜ 0.05).No recurrence was detected in the 2 groups during the follow-up.Conclusion The short-term efficacy and incidence of complications of full-thickness myotomy and circular myotomy are comparable,while the operation time of patients who received full-thickness myotomy is shorter.
