Chinese Journal of Obstetrics and Gynecology 2001;0(01):-
Objective To investigate mRNA expression of matrix metalloproteinase (MMP-9) and tissue inhibitor of metalloproteinase (TIMP-1) in ectopic endometriosis tissue and uterine endometrium from women with and without endometriosis. Methods Thirty-eight women with endometriosis (Revised American Fertility Society classification, RAFSⅠ-Ⅳ) were selected as study group. Thirty-eight specimens of ovarian endometrioma(ovarian chocolate cysts, OCC), 16 red peritoneal endometriotic lesions(RPL), and 35 matched eutopic endometrium(Eu) were collected from them simultaneously at the time of surgery. Twenty specimens of endometrium from reproductive women undergoing laparoscopic surgery without endometriosis were obtained as control group. The mRNA expressions of MMP-9 and TIMP-1 were detected by reverse transcription polymerase chain reaction (RT-PCR). Results Expression of TIMP-1 mRNA was detected in all samples. The level from endometriosis patients and control group was similar(2.31?1.21, 2.40?0.89). However, ectopic endometrium expressed significantly fewer TIMP-1 mRNA(OCC 1.67?0.79, RPL 1.45?0.68)compared with eutopic endometrium from both endometriosis and endometriosis-free patients(P

Objective To Investigate the expression of metallothionein (MT) and p53 in non-small cell lung carcinoma(NSCLC). Methods The expression of MT and p53 was detected by immunohistochemical method in the paraffin-embedded specimens of 73 NSCLCs and 15 normal bronchial mucosal tissues(NBMT). Results [WTBZ]The positive rates of MT and p53 expression in NSCLC were 54.8%(40/73)and 65.8%(48/73), respectively, and in NBMT were 20.0%(3/15)and 33.3%(5/15), respectively. The positive rates of both MT and p53 in NSCLC were significantly higher than those in NBMT(P0.05). The positive rates of MT and p53 were closely correlated with the histological grades and lymph node metastasis of NSCLC(P

Objective To explore the feature of epileptiform discharges during day and night in patients with sleep epilepsy and its diagnosis value. Methods Ambulatory EEG (AEEG) was performed continuously for 24 hours in 91 patients with sleep epilepsy. The frequency of epileptiform discharges in wake phase and sleep phase were analyzed. Results Epileptiform discharges were observed in 71 patients. 4 patients showed epileptiform discharges only in wakefulness, 41 only in sleep and 26 both in wakefulness and sleep. 34 patients showed epileptiform discharges only in stage 1 and 2 of NREM sleep, and 33 patients displayed epileptiform discharges in whole cycle of sleep. Seizure frequency in the patients with epileptiform discharges in wakefulness was higher than those without epileptiform discharges or with epileptiform discharges in sleep (both P

Objective To evaluate the clinical efficacy and safety of traditional Chinese medicine on internal and external treatment of acne.Methods 128 patients in Dermatology Department of Xiyuan Hospital CACMS from May 2012 to March 2013 were collected and randomly divided into Chinese medicine group and western medicine group.The patients of Chinese medicine group were divided into invasion of the Lung by Wind-Heat syndrome and damp-heat oflmg and stomach syndrome,respectively taking acne liquid 1 or 2 orally and using the herb mask once a week.The western medicine group took Roxithromycin Capsules orally and smeared 0.3% Viaminate and Vitamin E Cream.The treatment period lasted for 6 weeks,and collected the photograph of the target lesion before and after research every 2 week and evaluated the efficacy.Result The total efficacy rate were 90.77% (59/65) and 74.60% (47/63) for Chinese medicine group and western medicine group respectively,with significant difference between them(x2=11.83,P<0.05).The efficacy rates were 87.50% and 93.94% for invasion of the Lung by Wind-Heat syndrome and damp-heat of lung and stomach syndrome respectively,with no significant difference between them(x2=0.416,P>0.05).The TCM symptom scores after treatment [Chinese medicine group (4.36 ± 2.45),western medicine group (8.62± 2.49)] had significant difference in two groups respectively compared with before treatment[Chinese medicine group(15.33±6.08),western medicine group(14.34±5.29),P<0.05].The difference of TCM symptom scores after treatment between the two groups also had a significant difference (P<0.05).The TCM symptom scores after treatment of invasion of the Lung by Wind-Heat syndrome group and damp-heat of lung and stomach syndrome group were (4.50±3.01) and (4.24±1.83),which had a significant difference compared with before treatment respectively[(15.37±7.03)and(15.29±5.13),P<0.05].Conclusion The TCM internal and external treatment on acne could reduce the number of lesions and improve TCM symptom scores.The effect of treating invasion of the Lung by Wind-Heat syndrome and damp-heat of lung and stomach syndrome with TCM was almost equal.

Objective:To investigate sinomenine (Sinomenine,SIN) effect on RAW264.7 cells polarization to M1 or M2 phenotype induced by lipopolysaccharide (LPS) or interleukin-4 (IL-4) .Methods:RAW264.7 cells were induced to polarize to M1 by LPS ,and to M2 by IL-4.Sinomenine effects on LPS or IL-4 induced macrophages:TNF-αand IL-10 secretion induced by different condition were detected by Enzyme linked immunosorbent assay (ELISA);The expression level of mRNA of Arginase1(Arg-1),Nitric oxide synthase(iNOS),suppressor of cytokine signaling protein-2(SOCS2) and suppressor of cytokine signaling protein-3(SOCS3) of M1/M2 phenotypes were detected by real time PCR respectively.Results:Sinomenine inhibited the increase of TNF-αsecretion,iNOS and SOCS3 mRNA expression level induced by LPS.Sinomenine inhibited the increase of IL-10 secretion and Arg-1 mRNA expression level induced by IL-4,but SOCS2 mRNA expression level was not affected by Sinomenine.Conclusion: Sinomenine can inhibite the macrophage polarization to M1 and M2 induced by LPS and IL-4.Sinomenine plays a regulatory role on imbalance of M1/M2,and is conducive to maintain the dynamic balance.

AIM: To investigate the effects of fluvastatin on the airway remodeling in a guinea pig model of asthma. METHODS: Asthmatic guinea pig model was established by intraabdominal injection of ovalbumin and aluminium hydroxide and challenged with ovalbumin once every other day for 60 days. 30 guinea pigs were randomly divided into three groups: control group ( n= 10), asthma group ( n= 10) and fluvastatin plus asthma group ( n= 10) in which fluvastatin was inhaled at concentration of 0.5 g/L 30 min before every challenging. The thickness of airway smooth muscle layers of every three groups were compared after Haematin-Eosin staining by image analysis system. The level of ras mRNA in airway were examined by Dot-blot molecular hybridization. The expression levels of ras p21 were also examined by immunohistochemical technique. RESULTS: The mean thickness of airway smooth muscle in asthma group was (74 27?3 30) micrometer, greater than that of control group [(38 57?3 37) micrometer ( P

Objective To explore the relationship between the expression of CD44v6,P16 protein and the invasion and metastasis in gastric carcinoma and to investigate the correlation between the expression of CD44v6 and P16 protein.Methods Immunohistochemical methods were used to detect the expression of CD44v6 and P16 protein in 110 cases of gastric carcinoma.Results In 110 cases of gastric carcinoma,the expression of CD44v6 and P16 protein were 72.7%(80/110)and 47.3%(52/110)respectively. The high level expression of CD44v6 protein and low level expression of P16 protein were positively correlated with the TNM staging,serosa infiltration,lympho node and liver metastasis of gastric carcinoma(P
