This research explored the synergistic effects and the potential mechanisms of RCE-4 and various nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of cervical cancer Ca Ski cells. The MTT assay and CalcuSyn V2.0 software were used to detect cell proliferation and calculate the combination index (CI); the expression levels of various proteins were analyzed using Western blot assay; mitochondrial membrane potential (MMP) was assessed using JC-1 staining; acridine orange/ethidium bromide (AO/EB) double-fluorescence staining was used to detect the apoptosis of Ca Ski cells; a co-immunoprecipitation (Co-IP) assay was used to analyze the relative content of Bcl-2-Beclin 1 complex in Ca Ski cells. The results demonstrate that the combination of RCE-4 and NSAIDs increases the inhibition of Ca Ski cells compared to the single-RCE-4 group, and celecoxib provided the best synergistic effect among the four NSAIDs tested, with a CI of 0.32. The combination of RCE-4 and celecoxib significantly down-regulated the expression of cyclooxygenase-2 (COX-2) and nuclear transcription factor-κB (NF-κB), and promoted the expression of non-steroidal anti-inflammatory drugs activity gene-1 (NAG-1). In addition, autophagy induced by RCE-4 was markedly inhibited in combination with celecoxib, which was associated with down-regulation of the expression of microtubule-associated protein 3 (LC3)-II, Beclin 1, p62 and autophagy-related gene (ATG) 3/4B/5/7/14. RCE-4-induced apoptosis was significantly enhanced by altering the depolarization of mitochondrial membrane potential and the expression of B cell lymphoma-2 (Bcl-2), B cell lymphoma-xl (Bcl-xl), Bcl-2 associated X protein (Bax), Bcl-2/Bcl-xl-associated death promoter (Bad) and cleaved cysteinyl aspartate specific proteinase (cleaved-caspase) 3/7/9. Furthermore, the formation of the Bcl-2-Beclin 1 complex was significantly inhibited in Ca Ski cells treated with RCE-4 in combination with celecoxib. Taken together, this research shows that the combination of RCE-4 and celecoxib has a significant synergistic effect on the proliferation of Ca Ski cells by promoting apoptosis, inhibiting autophagy and disturbing the formation of the Bcl-2-Beclin 1 complex, which may be a novel strategy to increase the sensitivity of anti-cervical cancer drugs.

Drug reservation wag investigated in 2077 community residents.We found that most drugs were obtained from the hospitals(83.78%),kept at a relatively lower place(69.23%),packed in box(75.25%),and did not meet the storage requirement(72.60%).Half of the overdue drugs(median time,12 months)were used for internal treatment.This study suggests that there might be unsafe drug storage in communities.

Objective To study the relationship between portal hypertension(PHT) and heme oxygenase-1(HO-1)mRNA expression in rats.Method An animal model of PHT induced by partial portal vein constriction was established to detect the expression of HO-1mRNA in the liver,spleen, and splenic vein of rats by situ hybridization method. Result HO-1mRNA was not detected in the liver, spleen, and splenic vein in the control group. In PHT rats, HO-1mRNA was not detected in the liver;but in the spleen,the expression of HO-1mRNA was 83.3%;in the splenic vein,the expression was 55.6%. Conclusions The PHT rat is in stress condition.The expression of HO-1mRNA in the spleen and splenic vein of PHT ratsare increased and the metabolic product of HO-1 may exacerbate the PHT.

Aim The effects of antibiotics and anticoagulants on mouse peritonaeum were ob-served to explore the factor of the peritoneal dialysis related sclerosing peritoni-tis. Methods The experimental models of peritoneal dialysis were established in miceby infusing different kind of drugs to the peritoneal cavity and the changes of the peri-toneal membrane for each drug at different time were observed by the autopsy and lightmicroscope for several weeks. Results Amikacin, Cefradine, Zinacef, Ciprofloxacin,Heparin and Urokinase could induce sclerosing changes of peritoneal membrane such asloss of peritoneal mesothelum infiltration of inflammatory cells and of proliferation fibrecell.These changes were irreversible after the drugs were stoped.Conclusion Thedrugs commonly used in peritoneal dialysis may in different degree result in peritonealsclerosis.

Objective To study the different ultrasonic features in patients of polycystic ovary syndrome (PCOS) with or without obesity based on body mass index (BMI), and to investigate whether certain hormonal factors correlate with ovarian morphology and blood flow, and to discuss the role of ultrasound combined with hormone test in the diagnosis of obese PCOS. Methods One hundred and five women with PCOS were recruited. Patients were divided into two groups according to BMI;obese PCOS group (OB-PCOS, n=32, BMI≥25 kg/m2) and non-obese PCOS (NOB-PCOS, n=73, BMI<25 kg/m2). The ultrasonic parameters of follicle number (FN), ovarian volume (Vol), resistance index (RI) of ovarian stromal blood, RI of uterine artery and serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), the ratio of luteinizing hormone and follicle-stimulating hormone (LH/FSH), progesterone (P), estradiol (E2), free testosterone (FT), prolactin (PRL), sex hormoe binding globulin (SHBG), fasting plasma glucose (FPG), fasting insulin (FINS), the extent of insulin resistance and hyperandrogenism (HOMA-IR) were measured and compared. The correlation of the ultrasonic parameters and hormonal factors were analyzed. Results The Vol of OB-PCOS group was significantly higher than NOB-PCOS group [(12.25±4.89) ml vs (10.73±2.30) ml, t=2.20, P < 0.05]. FN and uterine artery RI of OB-PCOS group had a rising trend and RI of ovarian interstitial was on a reducing trend compared with NOB-PCOS group. But the differences were not statistically significant. The levels of FINS and HOMA-IR in OB-PCOS group [(14.82±6.45) mU/L and (3.91±3.30)] were significantly higher than those in NOB-PCOS group [(8.04±4.57) mU/L and (1.64±1.20)] (t=4.87, 3.47, respectively, both P < 0.01). And FSH in NOB-PCOS group was significantly higher than OB-PCOS group [(5.95±1.91) U/L vs (4.65±1.88) U/L, t=-2.77, P<0.01]. In POCS patients, FN was significantly associated with LH/FSH (r=0.35, P<0.01), and FT (r=0.38, P<0.01). Vol was significantly associated with LH/FSH, BMI, HOMA-IR and FPG (r=0.27, P<0.05;r=0.25, P<0.05;r=0.40, P<0.01;r=0.32, P<0.01). RI of ovarian stromal blood flow was significantly associated with SHBG (r=0.28, P<0.05). In OB-POCS group, RI of uterine artery was significantly associated with PRL (r=-0.58, P < 0.05). Vol was significantly associated with HOMA-IR (r=0.47, P < 0.05). In NOB-POCS group, FN was significantly associated with LH/FSH (r=0.33, P<0.05), and FT (r=0. 56, P<0.05). Vol was significantly associated with FT (r=0.31, P < 0.05). Conclusion There are some differences in the ultrasound and endocrine parameters between obese and non-obese PCOS patients, and some correlations exist between them.

Objective To explore the method to carry out epidemiological investigation of chronic kidney disease (CKD) in rural area surrounding the Tarim Basin, and to elucidate the prevalence and risk factors associated with CKD among the Uygur adults in Moyu county. Methods A total of 1650 residents (age >18 years) from 15 villages in 3 rural town of Moyu county were randomly selected by using a stratified, multistage sampling. All the residents were interviewed and received physical examination and tested for random spot urine of albumin to creatinine ratio (ACR). Estimated glomerular filtration rate (eGFR) was calculated by modified factors of CKD were examined. Results Valid data of 1552 subjects were enrolled in the study. After the adjustment of age and gender component, the prevalence of albuminuria and reduced eGFR was 4.5% (95% CI 4.4-4.6) and 1.4% (95% CI 1.4-1.5) respectively. Approximately 5.4% subjects had at least one indicator of kidney damage. Age and hypertension were independently associated with CKD. Conclusions Experience and method of epidemiology investigation of CKD in the rural areas of Uygur are obtained through this study. The prevalence of CKD is 5.4% and the awareness is 12.5% in the Uygur adults of Moyu county. Independent risk factors associated with CKD are hypertension and age.
