ObjectiveTo evaluate the efficacy and safety of high-dose irbesartan in the treatment of mild and moderate proteinuria in patients with chronic kidney disease (CKD).MethodsA single center,prospective,observational study was performed.A total of 96 subjects were given irbesartan 150 mg/d for 4 weeks.Twenty-six were divided into single-dose ( 150 mg/d) irbesartan group when their clinical efficacy were eligible for improvement criteria and 70 were divided into high-dose (300-600 mg/d) irbesartan group when there were no effect for single-dose treatment.Both groups received treatment for 48 weeks.Then 24-hour quantitative urine protein,systolic pressure,diastolic pressure,TC,LDL-C,plasma albumin,serum creatinine,blood urea nitrogen,blood uric acid,serum potassium and ALT were determined.Results The proteinuria level after treatment in the single-dose irbesartan group was decreased by 68.3％ with a statistically significant difference( P ＜0.001 ).In the high-dose group,the dose of irbesartan was increased based on the ineffectiveness when treating with single-dose,and the proteinuria was decreased by 63.4％ (P ＜0.001 ).Total effective rate in treating proteinuria in high-dose group was 72.9％ (51/70).Among the blood pressure sub-groups,the effective rates for the normal blood pressure group and hypertension group in treating proteinuria were 68.2％ and 76.9％ respectively ( P ＞ 0.05 ).However,in the normal blood pressure group and hypertension group,the proteinuria was decreased by 61.9％ and 67.5％ respectively after treatment (P＜0.001,P＜0.01),while without difference between the two groups (P＞0.05).The effective rates of high doses of 300,450 and 600 mg/d of irbesartan in treating proteinuria were 70.8％,63.6％ and 66.7％,respectively.The difference in effective rates of treating proteinuria among different doses had no statistical significance ( P ＞ 0.05 ).No obvious increase of SCr value before and after treatment in high-dose group ( P =0.583 ).The increasing level of serum potassium in high-dose group after treatment was higher than that in the single-dose group ( P ＜ 0.05 ),but the highest concentration (4.8 mmol/L) was still within the normal range.The blood pressure of 3 cases who quit observation because of low blood pressure in high-dose group returned to normal after drug withdrawal.ConclusionHigh-dose irbesartan can effectively lower the mild and moderate proteinuria in CKD patients with a good safety and tolerance and the efficacy is independent of lowering blood pressure.

Objective This study aims to investigate the correlation of CD4+ CD25+ FOXP3+ Tregs and PD‐1+ CD4+ T cells located at cervical lesions and the prognosis of CIN .PD‐1 expression on T cells induces Tregs .Methods Cervical lymphocytes were collected from CIN patients and analyzed by FACS .Comparisons were made between populations of cervical Tregs and PD‐1+CD4+T cells in CIN regressors and non‐regressors .Results A median of 11 .8% of cervical CD4+ T cells were CD4+ CD25+ FOXP3+Tregs ,while a median of 30 .3% were PD‐1+ CD4+ T cells .The proportions of CD4+ CD25+ FOXP3+ Tregs and PD‐1+ cells were significantly lower in CIN regressors when compared with non‐regressors .Conclusion The prevalence of CD4+ CD25+ FOXP3+Tregs negative correlates with spontaneous regression of CIN ,suggesting that cervical Tregs may play an important role in HPV‐related neoplastic immunoevasion .

Glycogen storage disease (GSD) is a rela-tively rare inherited metabolic disease. However, its relative rarity implies that no metabolic centre has experience of large numbers of patients and experience with long-term manage-ment is limited. In addition, there is wide variation in meth-ods of medical treatment. With the development of medical care, life-expectancy in glycogen storage disease (GSD) has improved considerably. With ageing liver adenoma may de-velop which will bring about several complications-compres-sion, hemorrhage, or even transformation into carcinomas-and needs immediate intervention. In this paper, reviews for the mechanism and surgical intervention of GSD are presented.

In this paper, the function of the iel gene from baculovirus Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV), belonging to group Ⅱ nucleopolyhedrovirus, was studied in mammalian cells.We amplified the SeMNPV ie1 gene and expressed it by fusing to the C terminal of enhanced GFP protein in HEK 293 cells. Confocal microscopy revealed that the IE1-GFP fusion protein was localized in the nucleus of the mammalian cells. The promoter sequences of AcMNPV gp64, SeMNPV F protein and Drosophila hsp70 were also analyzed, to further study the function of SeMNPV IE1. The results showed that, in the absence of the hr sequence, IE1 improved the expression of the F promoter but didn't influence the gp64 promoter significantly, but IE1 moderately stimulated the hsp70 promoter.

It has been demonstrated that surgery is currently still the most effective approach to completely cure gastric cancer. However, while only 30%-40% of gastric cancer can obtain curative outcome through pure surgery, most of patients with gastric cancer would died of recurrence or distant metastasis of the tumor. It appears to be more critical to search for other therapeutic strategies for gastric cancer other than surgery. Molecular targeting therapy has become the focus and hotspot of comprehensive treatment of gastric cancer.

OBJECTIVE To investigate the prevalence of meticillin-resistant Staphylococcus haemolyticus(MRSH)and resistance in S.haemolyticus isolates. METHODS MRSH was detected by cefoxitin disc test and susceptibilities were tested by agar dilution method. RESULTS There were 86.4% of MRSH isolates.MRSH was highly resistant to penicillin,cefazolin,cefuroxime,ceftriaxone,tetracycline,ciprofloxacin,and clindamycin.The resistance rate to amikacin,rifampicine and chloramphenicol was 16.9%,11.2% and 28.1%,respectively.All isolates were susceptible to vancomycin and teicoplanin.Except for tetracycline,amikacin,rifampicin,and chloramphenicol,the resistant rate to other antimicrobial agents was significantly higher in MRSH than in MSSH. CONCLUSIONS MRSH is mostly occupied in S.haemolyticus isolates and resistant to most of antimicrobial agents.More attention should be paid to survey and detect these strains.

Objective To examine the protein expression of the nucleotide excision repair gene (ERCC-1) in patients with locally advanced cervical cancer and its relationship with the efficacy of radiotherapy and chemotherapy.Methods The expression of ERCC-1 protein in 88 patients with locally advanced cervical cancer treated in our hospital between 2007-2011 was measured using immunohistochemistry (IHC).The patients were divided into high-expression group (n=48) and low-expression group (n=40) based on the fluorescence intensity on the IHC staining.All patients received cisplatin (40 mg/m2 per week) during radiotherapy.The relationship between ERCC-1 protein expression and the clinicopathological factors of cervical cancer was analyzed using the chi-square test.Survival was calculated using the Kaplan-Meier method and compared by the log-rank test.Multivariate prognostic analysis was performed using the Cox model.Results The overall response rate (CR+PR) was 81%(39/48) in the high-ERCC-1 expression group and 85%(34/40) in the low-ERCC-1 expression group (P=0.641).ERCC-1 protein expression was associated with recurrence and metastasis (P=0.043,0.043).The 5-year survival rate was significantly higher in the low-ERCC-1 expression group than in the high-ERCC-1 expression group (65% vs.42%, P=0.029).Conclusions Patients with high ERCC-1 protein expression are more likely to have local recurrence and distant metastasis than those with low ERCC-1 protein expression.ERCC-1 protein expression may be a clinically significant biomarker for predicting the prognosis of cervical cancer patients.

Objective To determine the relationship between hyperhomocyseinemia and atherosclerosis in hemodialysis patients.Methods Plasma total homocysteine (tHcy)concentrations were measured by using fluorescence polarization immunoassay.Carotid initial-medial thickness(IMT)was measured by echocardiography.Cardiovascular parameters including carotid Young elastic index and the prevalence of atherosclerosis plaques were calculated by established formulas.Results The prevalence of hyperhomocyseinemia was 68.3% in the hemodialysis patients.The folate and vitamin B_(12) concentrations were higher in patients than those in controls.Cartid IMT,carotid Young elastic index and the prevalence of atherosclerosis plaques were positively and independently correlated with tHcy (r=0.34,0.31,0.23).Multivariate stepwise regression indicated that the correlation also existed independently of other conventional risk factors such as age,sex,blood pressure,Scr,glucose.Conclusion The results indicate that hyperhomocyseinemia may be an independent risk factor for atherosclerosis found in hemodialysis patients.

Objective To investigate the causes of upper gastrointestinal bleeding (UGB), and some relative factors. Methods The UGB in 1 869 patients examined endoscopically between 1982－ 1996. Results 1.The most common causes of UGB were peptic ulcer (31.5％ ), gastric cancer(19.3％ ), and AGML(17.5％ ), and the rate of severe bleeding was highest in esophageal varices(49.4％ ). 2.Between 1982－ 1986,1987－ 1991,and 1992－ 1996, the rates of UGB were 22.3％ ,12.0％ ,and 13.4％ respectively. 3. The rate of UGB in male and female patients were 17.5％ and 8.9％ ; their difference is statistically significant(P
