Objective To investigate the effect of ectopic pregnancy tubal resection or common disease retention on female reproductive endocrine and menstrual traits.Methods 286 patients with ectopic pregnancy lapa-roscopic operation were selected.According to the different treatment methods,the patients were divided into resection group (n =199),retention group 87 cases,in surgical operation on the third day and the thirtieth day and tested for female reproductive hormone (P,LH,FSH,E2 )and human chorionic gonadotropin (hCG).Results Resection group in the third day after surgery of FSH[(8.5 ±4.9)IU /mL]was significantly higher than that of preserving group[(3.9 ± 0.9)IU /mL],with significant difference (t =5.44,P <0.05),the amounts of LH,E2 ,P and HCG were insignificant (t =0.56,1.24,0.82,all P >0.05).30 days after the surgery,there was no significant difference between the two groups in FSH,LH,E2 ,P and HCG (t =0.92,0.77,1.02,0.65,all P >0.05),but at the age of more than 40 years old and bilateral absence of fallopian tube in patients with,menorrhagia and menstrual cycle change obviously,and female ovarian endocrine function to reduce the clinical symptoms.Conclusion Tube resection has some influence on the ovarian function of tubal ectopic pregnancy,especially older,lack of bilateral fallopian tube.

Objective To investigate the effect of geldanamycin(GA) on the expression of HSP(HSP90,HSP70,HSP27) and oncoprotein(mutant p53,CDK4) in human breast cancer cell line MDA-MB-435s.Methods Proliferation of MDA-MB-435s cells was measured with MTT assay.The mRNA expression levels of HSP90,HSP70 and HSP27 were detected by RT-PCR.The protein expression levels of HSP90,HSP70,HSP27,mutant p53 and CDK4 were detected by Western blot.Results GA inhibited the proliferation of MDA-MB-435s cells in a time-dose dependent manner.The expression level of mRNA and protein of HSP90,HSP70 and HSP27 were increased,and the increasing of HSP70 was the most significant,while the protein expression level of mutant p53 and CDK4 in MDA-MB-435s cells were reduced obviously after 48-hour treatment with 400 nmol/L GA as compared with that of control cells.Conclusion GA inhibits the proliferation of MDA-MB-435s cells by down-regulating the level of mutant p53 and CDK4 protein,and GA involves in the protection of cell stress through increasing the expression of HSP90,HSP70 and HSP27.

Objective To observe the effect of intellectual activity on the cognitive function of the elderly.Methods The longi-tudinal follow-up study and the cross-sectional study were undertaken among physical examination people.The intellectual activity group (92 cases,more than 60 years old)often to take part in any one or more of the following activities for 5 years and above:pla-ying chess,playing the game of go,playing mahjong,playing cards,playing checkers,calligraphy,painting,reading,etc.The frequen-cy of intellectual activity was more than once per week at least.According to gender,age and educational level,92 cases were screened out as the control group and the control group was not to take part in above-mentioned intellectual activities or occasionally attend.The respondents had no baseline cognitive impairment.MoCA,MMSE,ADL and self-made questionnaire were adopted to conduct the evaluation.One year later when health check-up,the above-mentioned scales were used to evaluate again.The score changes were compared between the control group and experimental group.Results When enrolling,there was no significant differences in the MoCA scores,MMSE scores and ADL scores between the two groups.One year later,the comparison of the MMSE scores and ADL scores between the control group and experimental group had no significant difference (P>0.05).The Mo-CA scores manifested 2 cases (2.2%)of below the critical value of cognitive impairment in the experimental group and 6 cases (6.5%)in the control group,reaching the mild cognitive impairment(MCI)standards,the difference between the two groups showed the statistical significance (P<0.05).Conclusion The intellectual activity may be beneficial for the prevention of cognitive decline of the elderly and the MoCA scale is more suitable for screening MCI.

To investigate whether low density lipoprotein (LDL), very low density lipoprotein (VLDL), oxidized LDL (OX-LDL) and VLDL (OX-VLDL) could induce the cultured human endothelial cells (ECs) to express high levels of macrophage inflammatory protein lα (MIP-lα) and vascular cell adhesion molecule 1 (VCAM-1) mRNA. LDL and VLDL were isolated from normal human blood donors by density gradient ultracentrifugation and oxidized by Cu2+. The cultured human umbilical vein ECs were incubated with native LDL, VLDL, OX- LDL and OX-VLDL respectively, for 24 h, and in the control group no lipoproteins were added. Total cellular RNA was extracted from the cultured ECs by guanidinium isothiocyanate method. The expression of MIP-lα and VCAM-1 mRNA was detected by dot blotting analysis with two probes of digoxigenin-labeled MIP-lα and VCAM-1 cDNA fragments. The results showed that the cultured ECs could express MIP-lα and VCAM-1 mRNA. Incubation of ECs with LDL and VLDL led to a slightly increased expression of MIP-1α and VCAM-1 mRNA, whereas exposure of ECs to OX-LDL and OX-VLDL resulted in a significant increase ofMIP-1α mRNA expression that was 3. 2- and 2. 5-fold as much as that of the control group, respectively, and the VCAM-1 mRNA expression was increased as well, which was 2. 6- and 2. 17-fold as much as that of the control group respectively. It was suggested that lipoproteins especially oxidized lipoproteins could induce the expression of MIP-1α and VCAM-1 mRNA in ECs, which might play an important role in the recruitment of monocytes into the intima.

Objective To discuss the X-knife radiosurgery (XKS) in the treatment of brain metastasis of lung carcinoma. Methods A total of 100 patients with similar prognostic factors were divided into two groups with 50 patients in each group, receiving either whole-brain radiotherapy alone (30~40 Gy/3~4 weeks) (Radiotherapy Group) or XKS combined with radiotherapy (Combination Group). In the Combination Group, 27 patients received XKS with single fraction of radiation, with a median prescription dose of 14.2 Gy, and the other 23 patients received multiple fractions of radiation (5~10 Gy/f, 3 times weekly), with a total dose of 15~30 Gy. Results In the Combination Group and the Radiotherapy Group, the median survival time was 16.4 and 10 months, respectively (P=0.0064), the 2-year local tumor control rate was 88% (44/50) and 44% (22/50), respectively (?2=21.569,P=0.000), and the effective rate under CT or MRI scanning at 1~3 months after treatment was 87.5% (35/40) and 52.2% (24/46), respectively (?2=16.497,P=0.001). An analysis on the cause of death showed that 11.9% of patients (5/42) in the Combination Group died from brain metastasis, which was significantly lower than that in the Radiotherapy Group (55.6%, 25/45) (?2=25.908,P=0.000). The incidence of complications was not significantly different between the Combination Group (8%, 4/50) and the Radiotherapy Group (4%, 2/50) (?2=0.709,P=0.400). Conclusions Combined use of X-knife radiosurgery and routine radiotherapy has better therapeutic effects than radiotherapy alone for treating brain metastatic tumor.

OBJECTIVE: To investigate the protective effects of Chaiqin Chengqi Decoction (CQCQD), a compound traditional Chinese herbal medicine, on acinar cells and the changes of intracellular calcium concentration ([Ca(2+)]i) in acute pancreatitis (AP) rats. METHODS: CQCQ serum (CQCQS) was prepared by intragastric administration of CQCQD in SD rats, and AP was induced in SD rats by biliary-pancreatic duct ligation method. Pancreatic acinar cells were isolated by collagenase digestion and co-incubated with the drug serum containing CQCQD in vitro, then cell viability was determined by methyl thiazolyl tetrazolium (MTT) method and intracellular fluorescent intensity (FI) was observed and analyzed to investigate the changes of intracellular calcium concentration ([Ca(2+)]i). RESULTS: Both 5% and 10% CQCQS could improve the viability of pancreatic acinar cells in AP rats (P<0.05), and 10% CQCQS was more effective than 5% CQCQS (P<0.05). [Ca(2+)]i was elevated in AP rats (P<0.05), while the level of [Ca(2+)]i elevation was reduced after CQCQS treatment (P<0.05). CONCLUSION: CQCQD has a protective effect on pancreatic acinar cells of AP rats, which may be associated with its inhibition effect on intracellular calcium overload.

AIM:To detect the effect and underlying mechanism of parthenolide ( PN) on neointimal hyperpla-sia.METHODS:After 1 week of high-fat feeding, 30 male New Zealand white rabbits (2.0~2.3 kg) were randomly di-vided into 6 groups: sham +NS, rabbits received 0.9% normal saline after sham operation; sham +DMSO, rabbits re-ceived DMSO after sham operation;balloon injury(BI)+NS, rabbits received NS after balloon injury;BI+DMSO, rabbits received DMSO after balloon injury;BI+PN low, rabbits received PN at 1 mg/kg after balloon injury;BI+PN high, rab-bits received PN at 2 mg/kg after balloon injury .The drugs were intraperitoneal injected once a day after the operation until sacrifice.After fed with high-fat diet for 4 weeks, the intima-media thickness, the expression of caspase-1, IL-1β, the lev-els of IL-8, TC, TG, LDL and HDL in the serum were measured .RESULTS:Compared with sham +DMSO group, the thickness of intima, the amount of caspase-1, IL-1βand IL-8 in BI +DMSO group were significantly increased ( P <0.05).The levels of caspase-1, IL-1βand IL-8 were significantly decreased in BI +PN high group compared with BI +DMSO group (P<0.05).CONCLUSION:Neointimal hyperplasia is suppressed by PN after balloon injury , the potential mechanism may be associated with its anti-inflammatory role .
