Chongqing Medicine 2016;45(21):2900-2902
Objective To investigate the role of Rho kinase on collagen(COL)Ⅰ and Ⅲ expression of human renal tubular epithelial cells .Methods Human kidney tubular epithelial (HK‐2) cells were cultured in the RPMI‐1640 culture solution containing 15% fetal bovine serum .After 30 min pretreatment by the ALD receptor antagonist eplerenone(10 μmol/L) and Rho kinase inhibi‐tor Y27632(1 μmol/L) ,100 nmol/L ALD acted the HK‐2 cells for 24 h .The expressions of collagenⅠ and Ⅲ mRNA in each group were detected by real time PCR and the expression levels of COL Ⅰ ,Ⅲ and Rho kinase protein were detected by ELISA .Results ALD could up‐regulate the expressions of COLⅠ ,Ⅲ mRNA in HK‐2 cells ,and increased the levels of Rho kinase ,COLⅠ and Ⅲprotein ,while the Rho kinase inhibitor Y27632 and ALD receptor inhibitor eplerenone could antagonize these effects .Conclusion ALD could activate Rho kinase signal transduction pathway in HK‐2 cells and accelerate the progression of tubular interstitial fibro‐sis via Rho kinase induced expression of COL Ⅰ and Ⅲ .

Objective To study the effects of an extended-interval dosing regimen of gonadotropin releasing hormone agonist(GnRH-a) in the treatment of adenomyosis. Methods 20 patients with adenomyosis who asked for medicine treatment were divided into two groups randomly(n=10). The patients in the study group were given four doses of triptorelin depot 3. 75mg every 6 weeks in a new extended-interval dosing regimen. The other patients in the control group were given triptorelin 3.75mg in the conventional depot regimen of six doses,each given 4 weeks apart. The changes of degree of dysmenorrhea and the uterine volume were investigated. And the level of sexual hormone was also detected both before and after therapy.Results After six months of therapy,the reliving rate of dysmenorrheal was 100% both in the new regimen and the conventional regimen. The uterine volume was reduced at 46.7 % and 47. 5 % . And the level of LH, FSH and E2 were decreased significantly(P 0.05).Conclusion The use of the extended-interval dosing regimen of triptorelin depot in adenomyosis results in a consistent hypoestrogenised state,which is similar to that achieved by the conventional regimen. The new regimen thus reduces the cost of treatment obviously.

Objective To investigate effect of first, second, and third trimester placental factors (PF) on CD4, CCR5, and CXCR4 expression in human peripheral blood lymphocytes (PBLs), and to explore their influence on human immunodeficiency virus (HIV) vertical transmission.Methods Human peripheral blood mononuclear cells (PBMCs) were treated with first, second,and third trimester PF (concentration 25%) respectively for 24 hours. The expression of CD4, CCR5,and CXCR4 in PBLs, and the percentages of CCR5+, CXCR4+,and CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes were determined with flow cytometry.Results All trimester PFs reduced CCR5 expression in PBLs. The efficiency of the first trimester PF was higher than that of the second and third trimester PF. The percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of PF groups was significantly lower than that of the control group, and the percentage of CCR5+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the second and third trimester group. The percentages of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of PF groups were significantly decreased as compared with the control group, and the percentage of CCR5+CXCR4+ cells in peripheral blood CD4+ lymphocytes of the first trimester PF group was significantly lower than that of the third trimester PF group.Conclusion PF can reduce the expression of CCR5 in human PBLs and peripheral blood CD4+ lymphocytes, indicating that PF might reduce R5 virus infection via preventing HIV entry, and might play an important role in reducing R5 virus intrauterine infection.

The individual intervention control of risk factors in high-risk population is one of key preventive measures of chronic disease.A total of 312 volunteers consulted physicians in one selected community.And 23 high-risk individuals of chronic disease were screened.The physicians customized the limit or requirement of diet,activity,tobacco and alcohol for each individual and made interventions of life behaviors according to the plans.The results showed that physical state of 20 (87%) of them converted from high-risk to health after interventions.Therefore customized control plan of individual risk factors is an effective control method of chronic disease.

Objective To investigate the distribution of islet autoantibodies (GAD-Ab, IA2-Ab, IAA) in new-onset diabetic patients with unprovoked ketosis and their association with clinical characteristics and pancreatic ? cell function.Methods Islet autoantibodies, including GAD-Ab、IA2-Ab and IAA were detected in 161 new-onset diabetic patients with unprovoked ketosis by radioligand assay. Prevalence of positive islet autoantibodies was compared among groups with different ages, body mass indexes (BMI), severity of ketosis and fasting C peptide (FCP) levels. Clinical characteristics and pancreatic ? cell function were compared between groups with positive and negative islet autoantibodies.Results One or more kinds of islet autoantibodies were detected in 68 from the 161 subjects (42.2%), with higher prevalence of positive islet autoantibodies in the patients aged equal to or less than 20 years, of BMI equal to or less than 18.5 and with FCP equal to or less than 300 pmol/L. Younger age of onset, lower BMI, more severe ketosis and poorer islet endocrine function were found in patients with positive islet autoantibodies, as compared with those with negative ones.Conclusions In diabetic patients with unprovoked ketosis, the younger, the lower C peptide and the lower BMI they are, the higher prevalence of positive islet autoantibodies, the more possibility that they are classified as type 1A diabetes and the less possibility as type 1B diabetes or type 2 diabetes.Pancreatic ? cell function was poorer in patients with positive islet autoantibodies,which should be treated with insulin as earlier as possible.

AIM:To study the effects of sesamin (Ses) on attenuating renal injury in spontaneously hyperten-sive rats (SHR) and its relationship with PI3K/AKT/mTOR signaling pathway.METHODS:Spontaneously hypertensive rats were randomly divided into 4 groups:model (SHR) group, Ses low-dose (80 mg/kg) group, Ses high-dose (160 mg/kg) group and captopril (30 mg/kg) group.Another 7 WKY rats were given 0.5%sodium carboxymethylcellulose ( CMC-Na, the solvent was used to dissolve the drugs) as control group.Meanwhile, the rats in drug treatment groups were given the corresponding drugs.All animals were administered intragastrically once a day, and the blood pressure was measured every 2 weeks before and after the beginning of the administration.After 12 weeks, blood urea nitrogen ( BUN) , serum creatinine ( SCr ) , urine micro-albumin ( U-mAlb ) , malondialdehyde ( MDA ) and superoxide dismutase ( SOD ) were measured.The pathological changes of the renal tissues were observed under microscope with HE and Masson staining.Ap-optotic rate of nephridial tissue was determined by TUNEL method.The protein levels of p-AKT, p-mTOR, 4EBP1, S6K1, Bcl-2 and Bax were detected by Western blot.RESULTS:Ses decreased the diastolic blood pressure of SHR, significantly ameliorated the pathological damage in the nephridial tissues.Compared with model group, Ses was obviously reduced the contents of SCr, BUN, U-mAlb, MDA and apoptotic rate of the kidney, decreased the protein levels of p-AKT, p-mTOR, 4EBP1, S6K1 and Bax, and increased the protein expression of Bcl-2 and SOD activity.CONCLUSION:The protective effects of Ses against renal injury in SHR may be related to decreasing blood pressure, increasing anti-oxidative stress, re-straining apoptosis and inhibiting over-activated PI3K/AKT/mTOR signaling pathway.
