Objective To isolate,purify human endometrial stromal cells,and culture these cells in vitro,for the further research of pathogenesis of intrauterine adhesions.Methods Human endometrial stromal cells were separated and purificated by enzymo ly-sis,mesh filtration and pasted wall,then the stromal cells of purification were cultured.Phenotype of stromal cells was identified by immunohistochemistry.Results The stromal cells became adherent 30 min after culture.Two types of stromal cells were found. One was spindle and the other was polygonal.Immunocytochemical staining method revealed that vimentin was positive in both types of stromal cells,and the positive rate was above 9 5%;meanwhile,cytokeratin was negative in both types of stromal cells, which indicated that these cells were endometrial stromal cells.The isolated endometrial stromal cells can be cultured in vitro.Con-clusion Highly purified stromal cells of human endometrium could be obtained by enzymolysis,mesh filtration and pasted wall pur-ification,and the cultured stromal cells could passage to limited generations.

This study was conducted under the background of the internationalization of traditional Chinese medicine (TCM) terminology. Current TCM symptom terminology related to sweat was taken as basis in the extended study. The ICD classification of multiple axis and hierarchical level was used as guidance thought. This paper proposed the principle of detailed classification of TCM sweat symptoms and finally made classification rules for TCM sweatsymptoms. This study has promoted the development of TCM terminology standardization.

Objective:By monitoring the lung compliance,oxygenation index(OI),CC16、IL-8 in plasma,observe whether the protective lung ventilation in patients undergoing gynecological laparoscopic surgery can improve the respiratoryw function and reduce lung injury.Methods:40 cases of ASA grade Ⅰ-Ⅱ were selected,and 40 patients were treated by elective laparoscopic radical resection of cervical cancer.The patients were divided into two groups according to the random number table method in 40 cases.Mechanical ventilation in general anesthesia,A group used traditional intermittent positive pressure ventilation mode,tidal volume is set to 10ml/KG (PBW);B group used lung protective ventilation strategy,tidal volume is set to 6ml/KG (PBW) + 5cmH2O PEEP + recruitment manoeuvres.For patients before pneumoperitoneum(T0),2 hours after pneumoperitoneum (T1),4 hours after pneumoperitoneum (T2)MAP,HR,CVP,RR and C were observed.In pneumoperitoneum (T0),2 hours after pneumoperitoneum(T1),4 hours after pneumoperitoneum (T2),2 hours after operation(T3),24 hours after surgery(T4) venous,IL-8,CC16 content detection.Results:Before pneumoperitoneum,two groups of patients with pulmonary compliancethe difference was statistically significant(P ＜0.05).Compared T1 、T2 with T0 in A group and B group,the pulmonary compliance all decreased and there existed significant deference(P＜0.05).Notably,A group decreased evidently(P＜0.05).T0,T1,T3,T4 time points in two groups of patients with oxygenation index,the difference was statistically significant (P ＜ 0.05).Two groups of patients with CC16,IL-8content in T1,T2,T3,T4 time point,the difference was statistically significant (P ＜ 0.05).Conclusions:Lung protective ventilation strategy can improve respiratory function in patients with gynecological laparoscopic surgery,and reduce the incidence of lung injury.

Objective To study the effect of the Hushengujingfang (HSGJF), a traditional Chinese prescription, on the biological behaviour of rat mesangial cell (MC). Methods MC was cultured in vitro, and the serologic pharmacology method was employed. The cells were divided into serum groups of HSGJF, LPS group and control group. Added the different concentration actors to MC and cocultured then made into unicell suspension. After examining it by flow cytometry, the percentage of G 0 /G 1 period, S period, G 2 /M period in cell cycle and the inhibition percentage of S period and cell proliferation index were calculated. Result The actors of different concentration had different effects to the multiplication cycle of MC and delayed the entry of cell cycle at G 0 /G 1 period. HSGJF induced apoptosis of MC. Conclusion One of action mechanism of HSGJF treating mesangial proliferative nephritis and other renal glomerular diseases is to inhibit MC proliferation and promote apoptosis.

ObjectiveTo analyze the polymorphism of HLA-A,B,and DRB1 alleles and their haplotypes in Chinese Man population.Methods Frequencies of HLA-A,B and DRB1 alleles and haplotypes were estimated by maximum-likelihood estimation method based on the genotypes of 2183 Chinese Man bone marrow donors.ResultsA total of 18 HLA-A alleles,44 HLA-B alleles and 15 HLA-DRB1 alleles were detected in Man population,and the most frequent alleles were A*02,A*11,A*24,A*30,A*33,B*13,B*35,B*46,B*51,B*40(B60),B*40(B61),B*15(B62),DRB1*04,DRB1*07,DRB1*08,DRB1*09,DRB1*11,DRB1*12,DRB1*13,DRB1*14 and DRB1*15.A*30-B*13,A*02-DRB1*15,B*13-DRB1*07 and A*30-B*13-DRB1*07 were the most frequent haplotypes in Man population for A-B,A-DRB1,B-DRB1 and A-B-DRB1 haplotype,respectively.The number of haplotypes with frequency ≥ 0.01 for A-B,A-DRB1 and B-DRB1 haplotype was 31,24 and 27,respectively,and ≥ 0.005 for A-B-DRB1 haplotype was 32.There were 14 in A-B,3 in A-DRB1,14 in B-DRB1 and 38 in A-B-DRB1 haploypes that showed strong linkage disequilibrium with ALD≥0.40.ConclusionsThe distribution of HLA-A,B and DRB1 alleles and haplotypes in Man population was similar to that in Northern Chinese Han population.

Objectives To construct prokaryotic expression plasmid of rat surfactant protein C (sp-c) gene under hyperoxia and expression in E.coli. Methods Twenty-one-day-old SD premature rats were exposed to 85%hyperoxia 12 hours after birth. The rats were executed after 7 days and their RNA were extracted from lung and cDNA was synthesized and amplified. And then the cDNA was cloned into pMD18-T vector and confirmed by enzyme digestion and sequencing. After the prokaryotic expression vector pET-28a(+)-sp-c was constructed, the recombinant plasmid was induced by IPTG and expressed in E.coli BL21 strain. The fusion protein was analyzed by SDS-PAGE and Western blotting. Results The pET-28a(+)-sp-c plasmid was constructed and the fusion protein with relative molecule mass of 21000 was highly expressed. Conclusions SP-C is successfully expressed in E. coli, which can be used to study the mechanism of action between SP-C and endoplasmic reticulum, the expression of SP-C in lung epi-thelial cell A549 and the impact of SP-C on proliferation, differentiation and apoptosis of AECIIs in future.

Objectives To investigate the expressions of endoplasmic reticulum stress (ERS)-related factors, glucose regulated protein 78 (GRP78) and C/EBP homologous protein (CHOP), in lungs of rats with bronchopulmonary dysplasia (BPD) and their relationship with pneumonocyte apoptosis, and further to explore the role of ERS-induced apoptosis in the pathogen-esis of BPD. Methods A total of 24 neonatal SD rats were randomly divided into control group and BPD group with 12 rats each. Rats in BPD group were exposed to 85%O2, while rats in the control group were exposed to air. Four rats in each group were sacriifced at 7, 14 and 21 days respectively after exposure. The expression of GRP78 in the lung tissues was examined by immunohistochemistry, the mRNA and protein levels of GRP78 and CHOP were detected respectively by real-time PCR and Western blot, and the apoptosis in lung cells were evaluated by TdT-mediated dUTP nick end labeling (TUNEL) assay. Results The mRNA and protein levels of GRP78 and CHOP, and the cell apoptosis in BPD group were signiifcantly different from those in control group (P<0.01) at different time points and increased over the time of hyperoxic exposure (P<0.01). Conclusions En-doplasmic reticulum stress may be initiated by hyperoxic exposure and apoptosis is induced via CHOP signal pathway, which is involved in the pathogenesis of BPD.
