Objective To investigate the causes,diagnostic methods,prevention and cure of postmenopausal bleeding(PMB).Methods The clinical and pathological data of 210 PMB patients admitted in this hospital were retrospectively analyzed.Results The causes for PMB were benign diseases(69.5%),the most of which were infec- tious diseases(49.5%),non-organic disease(20.5%)and malignant tumor(10.0%).Compared with benign diseases and non-organic diseases,the attack age of malignant tumor was higher[(67.1?6.9)years old],menopausal dura- tion was longer(11.6?2.9)years,bleeding duration was longer[(157.6?26.4)days],and mucous membrane was obviously thickened[(14.6?3.2)mm](P0.05).Conclusion The main cause for PMB is benign diseases,followed by non-organic diseases.More attentions should be paid to the PMB patients with higher attack age,longer menopausal duration and bleeding dura- tion,and obviously thickened mucous membrane,so as to be precautions to the occurrence of malignant tumor.

Objective To detect the expression of cyclooxygenase(COX) in human gastric cancer cell lines and its subcellular location of the isoforms. Methods Immunohistochemistry、RTPCR combined with laser scanning cofocal microscopy (LSCM) were used to investigate expression and distribution of COX. Results Positive staining of COX2 and COX1 protein was seen in human gastric cancer cell line MKN45、SGC7901 and AGS. However, the COX2 staining was absent and COX1 staining was weak in MGC803; though their mRNA in all the four cell lines. When compared to COX1,COX2 showed a stronger signal at both protein and mRNA levels of the gastric cancer cell lines, which was confirmed by double labeling and LSCM. The quantitative analysis of fluorescein intensity indicated the pixel intensity peak of COX2 reached 50～70, while COX1 only 10. LSCM also showed that COX2 was both cytoplasmic and nuclear envelope staining but COX1 only in cytoplasm. Conclusions In human gastric cancer, there is stronger expression of COX2 than COX1, and different distribution of the two isoforms implies their distinct roles in cell function.

Objective To investigate the effect of MT-1 and MT-2 in liver damage in chronic inorganic arsenate exposure mice and to explore the mechanism of arsenic-induced liver damage. Methods The male Kunming mice were randomly divided into control and exposed groups. The control group was given ordinary feed and tap water. The exposed group was given ordinary feed and 300 mg/L of sodium arsenite solution by drinking water. After 10 months of treatment, the activity of serum alanine aminotransferase (ALT), aspartate aminotransferase(AST) and globulin (Glb) content were determined. The total RNA was extracted by the TRIzol-phenol-chlorofor-method from the liver tissue. The quantity of the RNA was determined by spectrophotometry and its purity was judged at a ratio of A260/A280. Then real-time PCR(RT-PCR) was used to measure the mRNA expression of MT-1 and MT-2. Results Compared with the control group, serum ALT, AST activity and Glb content were higher and the MT-1 and MT-2 mRNA content was lower in the exposed group (P

Objective To explore the effect of HIPK2 on apoptosis of human kidney tubular epithelial cells (HKC) induced by cisplatin.Methods Apoptosis of HKC cells was induced by cisplatin and the expression of HIPK2 was detected by RT-qPCR and Western blot.Two HIPK2 siRNAs were designed according to gene sequence of HIPK2 and cell lines with HIPK2 knockdown were established through transfecting the HIPK2 siRNAs into HKC cells by liposome.The expression of HIPK2 mRNA and protein was detected by RT-qPCR and Western blot after induced by cisplatin.Then cell apoptosis was detected by Annexin V/PI after the HIPK2-knockdown cells were treated with cisplatin.Moreover,the expression of pro-apoptotic protein bax was detected by Western blot after HIPK2 was knockdown.Results The expression of HIPK2 mRNA and protein was down-regulated obviously on the process of HKC apoptosis which induced by dose-dependent cisplatin (P＜0.05).The transfection of siRNA could significantly reduce the expression of HIPK2 mRNA and protein in HKC (P＜0.05),which promotes the HKC cells apoptosis induced by cisplatin.Conclusions HIPK2 can suppress the HKC cells apoptosis induced by cisplatin.

Objective To investigate the effect of eosinophils(EOS)in asthmatic guinea pigs airway and explore the mechanism of antiasthma by inhaled arsenic trioxide. Methods The guinea pigs asthma models were established with ovalbumin(OVA)challenge method,2 groups received inhaled different doses of arsenic trioxide,and three control groups respectively received normal saline inhaled and high dose of arsenic trioxide by intraperitoneal injection and dexamethasone(DEX)intraperitoneally. EOS invaded and apoptosis with all of the groups were assessed after 7 days intraperitoneal injection or inhalation. Results Compared with group of inhaled normal saline, both EOS invaded and apoptosis in bronchus submuconsa were significantly different(P0.05)among groups of inhaled low dose arsenic trioxide [2.0 mg(kg?d)]and intraperitoneal injection with higher dose arsenic trioxide[5.0 kg/(kg?d)]and DEX[10 mg/(kg?d)]for these two parameters. Conclusions The mechanism of arsenic trioxide antiasthma with arsenic trioxide can decrease EOS amount in bronchial submucosa and accelerate EOS apoptosis, and relieve bronchial inflammation in asthma. For inhaled lower dose arsenic trioxide or intraperitoneal injection with high dose arsenic trioxide ,the effect of EOS is equivalent. The antiasthma effect of inhaled lower dose arsenic trioxide[2.0 mg/(kg?d)]is equivalent to intraperitoneal injection higher dose[5.0 mg/(kg?d)],and may be safe comparatively. The mechanism of antiasthma by inhaled arsenic trioxide is the same with DEX.

Objective To investigate the effects of Liraglutide on plasma FGF-21 level in patients with type 2 diabetes mellitus (T2DM). Methods Enzyme linked immunosorbent assay (ELISA) was used to measure plasma FGF-21 level in patients with T2DM and normal controls (NGT). Relationship between plasma FGF-21level and BMI, WHR, HOMA-IR, HOMA-IS, FFA was analyzed. After Liraglutide treatment, plasma FGF-21level was observed in patients with T2DM. Results Fasting plasma FGF-21 level was higher in T2DM patients than that in normal control group ( 1.81 ±0.32 vs. 1.32 ±0.09 μg/L, P ＜0.01 ). After Liraglutide treatment, WHR, BMI, FPG, 2hPBG, HbA1c and FFA in T2DM patients significantly decreased ( P ＜0.05 or P ＜0. 01 ),HOMA-IS remarkably increased (P ＜ 0. 01 ), and FGF-21 had no change. Conclusion Liraglutide and FGF-21may have different roles in insulin resistance.
