Objective To study the mechanism of Chinese Medicine in treating adenomyosis. Methods Thirty-seven patients in the Chinese Medicine treated group (17 cases of adenomyosis) and the control group (20 cases of adenomyosis, non-drug treated) underwent hysterectomy. Endometrium was looked as eutopic endometrium and adenomyosis as ectopic endometrium. Expression of MMP-9 and TIMP-1 in eutopic and ectopic endometrium were measured by immunohistochemical techniques. Meanwhile the levels of CA125 in serum were measured. Results The ectopic endometrium of the Chinese Medicine treated group expressed lower level of MMP-9, higher level of TIMP-1 and lower ratio of MMP-9/TIMP-1 than the ectopic endometrium of the control group (P<0.05). The levels of CA125 in serum were significantly decreased in Chinese Medicine group after treated as contrast with those in control group. Conclusion Chinese Medicine could reduce the level of CA125 and the ratio of MMP-9 and TIMP-1 to prevent the progression of adenomyosis.

MicroRNA (miRNA) is a kind of naturally occurring short non-coding small molecular RNA,which regulates gene expression at the posttranscriptional level through its sequence complementation with target mRNAs.Researches have shown that different malignant tumors,including diffuse large B cell lymphoma,have specific miRNA expression profiles.Therefore,miRNAs expression level of specimens of body fluids and tissues is expected to be the new indicator for assessing diffuse large B cell lymphoma.

Objective To investigate the effects of remifentanil on NF-κB activity in a rabbit model of myocardial ischemia/reperfusion (I/R) injury. Methods Fifty New Zealand white rabbits were randomly divided into 5 groups (n = 10 each): sham operation group (group S); group I/R; low dose of remifentanil group (group L); median dose of remifentanil group (group M); high dose of remifentanil group (group H). In group I/R, L,M and H, myocardial I/R was produced by occlusion of left anterior descending artery for 30 min followed by 120 min reperfusion.In group S and I/R,10 min before ischemia,normal saline was infused at 5 ml·l·h-1 via the external jugular vein until the end of 120 min reperfusion. In group L, M and H, remifentanil was infused at 1, 5 and 10ug·kg·min-1 respectively 10 min before ischemia until the end of 120 min reperfusion,and the other procedures were the same as those in group I/R. The myocardial tissues were taken at the end of 120 min reperfusion for determination of NF-κB expression which was used to reflect the activity of NF-κB and microscopic examination. Results The activity of NF-κB was significantly higher in group I/R, L, M and H than in group S. The activity of NF-κB was gradually decreased with the increase in the dose of remifentanil in group L, M and H compared with group I/R. The microscopic examination showed that remifentanil significantly attenuated I/R-induced injury in a dose-dependent manner. Conclusion Infusion of remifentanil reduces myocardial I/R injury through decreasing the activity of NF-κB in a doee-dependent manner.

Objective To study the loss of imprinting(LOI) of insulin-like growth factor Ⅱ(IGF2) and H19 genes in cervical carcinomas.Methods Polymerase chain reaction(PCR) method was used on DNA samples extracted from 40 cases of cervical carcinoma and 20 cases of normal control tissues to detect the heterozygosity of IGF2 and H19 genes.The LOI of IGF2 and H19 genes was detected by RT-PCR.Results The heterozygous frequency of IGF2 was 52% in cervical cancer samples.Comparatively,in 20 matched normal samples,13 cases showed the heterozygosity(65%).The biallelic expression of IGF2 was detected in 10 cases among the 21 informative cervical cancer samples(47.6%),however,1 case in 13 heterozygous samples of control group(7.7%)((P0.05).Conclusion LOI and LOH of IGF-2 and H19 genes are involved in cervical carcinomas.LOI of IGF2 and H19 may be involved in the initiation stage of carcinogenesis of cervical carcinoma.

Objective To study the relationship between fetal growth retardation(FGR) and expression of insulin-like growth factor-2 and H19 imprinted genes.Methods Immunoradioassay was used to detect the insulin-like growth factor-2(IGF2)level in cord blood from 42 pregnant women with FGR(FGR group) and 30 normal pregnant women(normal group).Reverse transcription-polymerase chain reaction method(RT-PCR) was used to detect H19 imprinted genes allele-specific expression level in placenta.Results The level of IGF2 in cord blood from FGR group was(1.52?0.20)?g/L.It was significantly decreased as compared with that from the normal group(1.97?0.21)?g/L(P

Objective To investigate the expression of H19 imprinted genes in the villus tissues of women with spontaneous abortion.Methods Reverse transcription-polymerse chain reaction method(RT-PCR) was employed to detect H19 imprinted genes allele-specific expression levels of the villus tissues extracted from 45 cases of spontaneous abortion and 30 cases of normal pregnancy.Results Nineteen cases of 21 heterozygous cases in spontaneous abortion samples showed billelic expression of H19(19/21),whereas no billelic expression was found in the normal pregnancy samples(0/13)(P

Objective:To analyze the pathologic types and clinical characteristics of lymphoma in Shandong, China. Methods:The clinical data of lymphoma patients admitted from September 2011 to September 2014 in Shandong Cancer Hospital and the Affiliat-ed Hospital of Shandong Academy of Medical Sciences were retrospectively analyzed. Data included age, sex, pathologic classification, and onset locus of lymphoma. Results:The clinical data of 520 lymphoma cases were collected. The ratio of male to female was 1.2:1, and the median age was 51 years old. Among these patients, 67 cases (12.9%) were Hodgkin's lymphoma (HL), whereas 453 cases (87.1%) were non-Hodgkin's lymphoma (NHL). Among NHL cases, 75.9% were B-cell NHL and 24.1% were T/ natural killer-cell NHL. Nodular sclerosis classical Hodgkin's lymphoma was the most common pathologic type of HL, comprising 52.2%. The age of HL onset did not present twin peaks. In NHL, 245 cases (54.1%of NHL) were diffuse large B-cell lymphoma (DLBCL). The constituent ra-tio of DLBCL was higher than in other countries and regions (18%to 42.7%), in which the ratio of male to female was 0.9:1, and the age of onset was slightly earlier (median age was 54 years old). Lymph nodes in the cervical region were the most commonly involved in the disease, and NHL extranodal onset was frequently observed. Conclusion:Among the 520 cases of lymphoma, DLBCL is the most common subtype. Most subtypes show male predominance, but female predominance was observed for DLBCL. The commonly involved sites of extranodal lymphoma are the nasal cavity and gastrointestinal tract.
