150 slides of vaginal sample of married women aged 16-49 years old at 8 village of Ha Tay province were investigated. In 51.6% of subjects, there is not pathological manifestation in 48.3% - inflammative damages, then 38.6% with chronical manifestation and 12.6% with acute PaP1 account for 62.6%, PaP2: 24.5% and PaP3: 0.13%. There is not any cancerous damage. Hygiene condition, obstetrical history and venerological diseases were factors related to inflammative state and cervix cell morphology change

From 1996 to 2000, 73 samples of renal biopsy in patients >16 years old with glomerulonephritis and nephrotic syndrome were study on light microscopy. Results: the rate of minimal change glomerulopathy was highest (72.6%), then was the rate of diffuse mesangial proliferative glomerulonephritis (20.6%). The rates of focal segmental glomerulonephritis, membranous proliferative glomerulonephritis, and membranous glomerulonephritis in this study were lower than the other studies. The changes in minimal change glomerulopathy are glomerular basement membrane thickened irregularly, widening and effacement of the visceral epithelial cell foot processes

Calcium phosphate ceramics, such as tricalcium phosphate (TCP) and hydroxyapatite (HA) are commonly used as bone substitutes. These materials have different physical and chemical properties and, therefore, display different interactions with the host tissue. Factors such as porosity,osteoconductivity,and biocompatibility seem to become increasingly important in the development of new artificial bone replacement materials. This article focuses on the relationship between the physical and chemical properties of calcium phosphate ceramics and the host tissue.

Objective To investigate the effect of telmisartan on the plasma brain natriuretic peptide (BNP) in patients with permanent cardiac pacing.Methods According to the method of simple random numbers,106 patients with permanent cardiac pacing were randomly divided into study group and control group,with 53 cases in each group.All patients received implanted operation of permanent pacemaker.The study group was given telmisartan tablets,1 time a day,1 tablet each time,until the end of follow-up.The control group was given valsartan.The plasma BNP was measured by the immunofluorescent assay before administration and at the end of follow-up.In addition,left ventricular ejection fraction (LVEF) and cardiac index (CI) was determined by echocardiography.Results The plasma BNP in two groups was lower than 100 ng/L before administration.At the end of follow-up,the plasma BNP changed slightly in study group,but increased in control group,and the plasma BNP in control group was higher than that in study group [(105.67 ± 15.64) ng/L vs.(73.23 ± 10.56) ng/L],and there was significant difference (P ＜ 0.05).LVEF and CI was stable within the normal range before administration and at the end of follow-up in study group [(58 ± 4)％ vs.(59 ± 5)％,(3.58 ± 0.32) L/(min· m2) vs.(3.56 ± 0.26) L/(min· m2)].LVEF and CI at the end of follow-up in control group was decreased compared with that before administration[(49 ± 3)％ vs.(56 ± 3)％,(2.97 ± 0.26) L/(min· m2) vs.(3.62 ± 0.29) L/(min· m2)],which was lower than that in study group[(49 ± 3)％ vs.(59 ±5)％,(2.97 ±0.26) L/(min·m2) vs.(3.56 ±0.26) L/(min·m2)],and there was significant difference(P ＜ 0.05).Conclusions Telmisartan can delay the increase of the plasma BNP in patients with permanent cardiac pacing,delay the onset of symptoms of heart failure,and improve the quality of life.So early administration of telmisartan is recommended for the patients with permanent cardiac pacing.

Objective To analyze the clinical efficacy of diacerein plus methotrexate and leflunomide in the treatment of rheumatoid arthritis in elderly patients.Methods Eighty elderly patients with rheumatoid arthritis seeking treatment at our hospital from September 2010 to December 2012 were divided into the treatment group (n =40) and the control group (n =40).Patients with osteoarthritis were excluded from enrollment.The treatment group was given diacerein,in addition to methotrexate and leflunomide,whereas the control group received methotrexate and leflunomide.Results Compared with the control group,the treatment group showed a lower swollen joint count [(0.93±0.21) vs.(3.43±0.69),t=10.728,P=0.013],a lower tender joint count [(1.15±0.46)vs.(3.6110.83),t=11.443,P=0.008],shorter morning stiffness (1.6±2.2 min vs.13.5±4.2min,t=11.164,P=0.011),and greater hand grip strength [7.97±1.53) kPa vs.(5.68±2.07)kPa,t=10.562,P=0.014].When measured by health assessment questionnaire (HAQ),visual analogue scale (VAS) and DAS28 scores,the treatment group also performed better than the control group.Additionally,the treatment group displayed a more favorable laboratory profile,which included the erythrocyte sedimentation rate (ESR) (9.51±4.32 mm/h vs.26.47±6.32 mm/h,t=9.892,P=0.028),C-reactive protein (CRP) [(2.34±0.57) mg/L vs.(8.13±2.14) mg/L,t=9.427,P=0.031],and rheumatoid factors (RF) [(231.3±45.5) kU/L vs.(283.3±68.4) kU/L,t=10.023,P=0.018].Furthermore,the adverse reaction rate was significantly lower in the treatment group than in the control group (15.0％ vs.37.5％,x2 =5.230,P=0.020).Conclusions Diacerein in combination with methotrexate and leflunomide has shown clearly positive outcomes in the treatment of rheumatoid arthritis in elderly patients and should be recommended in clinical treatment.

P13K/Akt signaling pathway is an classic anti-apoptotic,urge-survival signal transduction pathway.It plays important regulation and control roles in neurons apoptosis.PTEN ( phosphatase and tensin homolog deleted on chromosome 10) is a highly conservative tumor suppressor gene with a dual-specificity phosphatase activity.PTEN protein can specifically dephosphorylats the 3 position of phosphoinositides,antagonize the PI3K/Akt signaling pathway,as negativity regulation and control roles to cell survival and growth.This review summarizes the progresses of the composition,function in PI3 K/Akt and PTEN,and the relationship with developing brain after hypoxia-ischemia.

High mobility groupbox 1 (HMGB1),a highly conserved protein previously known as a DNA-binding protein involved in maintenance of nucleosome structure and regulation of gene transcription,was recently found to act as a potent proinflammatory cytokine during infection responses.Levels of HMGB1 increase in serum and tissues during infection,especially in sepsis.A growing number of studies have demonstrated that HMGB1 is a cytokine that can mediate inflammation and is a potential therapeutic target in experimental models of sepsis.In this article,we will describe the biological function of HMGB 1 and HMGB 1 inhibitors for a potential role of inflammatory disease treatment.

Cisplatin is widely used in lung cancer chemotherapy, but drug resistance seriously affects its efficacy.The mechanism of cisplatin resistance is not yet clear.Now it is widely recognized that P-glycoprotein (P-glycoprotein, P-gp) expression is associated with cisplatin resistance. Inhibition of P-gp expression can overcome cisplatin resistance and improve the treatment efficacy.

Teaching quality is the basis of higher education.This article compared the results of teaching supervision and evaluation between campus and affiliated hospitals of Qiqihar Medical University in 2011.Differences were found out and corresponding strategies were proposed in order to improve the teaching quality and train high-quality talents.

Surgical therapy should be the main method in treatment of rectal cancer.Along with the increase rate of undergoing anterior resection for rectal cancer,it is getting be paid more and more attention on postoperative anastomotic fistula as the main complications of rectal carcinoma.In recent research,anastomotic fistula occurred caused by various factors had also been put forward gradually,while the risk factors for postoperative anastomotic fistula were still remain unclear.Therefore,it is very important to understanding the risk factors in order to prevent the happening of the anastomotic fistula,and provide clinical basis for their necessary preventive colostomy.
