OBJECTIVE:To evaluate the expression on plasminogen activator inhibitor-1 (PAI-1) in the human renal biopsy of patients with CKD and analyze its clinical significance.METHODS:The expression of PAI-1 in 63 specimens of patients with CKD(CKD group) and 19 normal renal tissue(Control group) were detected by immuno-histochemistry.The expression of PAI-1 in the normal renal tissue were compared with the each phase CKD group.Meanwhile,The expression of PAI-1 in 16 patients with CKD treated by valsartan were compared with 47 cases not treated.RESULTS:Compare with the control group,the expression of PAI-1 in each phase CKD group was respectively drastically increased (P

This thesis studies professor WANG Shou-chuan’s clinical experience in treating atopic dermatitis with traditional Chinese medicine (TCM). Professor Wang believes that the key pathogeneses of atopic dermatitis are wind, dampness and toxins. The main therapy is clearing away wind, resolving dampness and removing toxins. It is differentiated as infant period, child period and adult period according to the patients’ age. Xiaofeng san, Bixieshenshi tang and Yangxuedingfeng tang are three main prescriptions in treating this disease. It is emphasized that toxin is the most important pathogenesis of atopic dermatitis, and removing toxins should be used in every period. Moreover, professor Wang is good at using insect medicine to clear away wind and stop itch.

Objective To evaluate the effects of angiotensin Ⅱreceptor antagonist (ARB) on expression of plasminogen activator inhibitor(PAI)-1 in the human renal biopsy of patients with chronic kidney disease(CKD)and analyse its clinical significance.Methods PAI-1 expression of 63 specimens with CKD was detected by immunohistochemistry and quantitative analysis was achieved by image analysis system. meanwhile, the patients'clinical data were collected,and PAI-1 expression of 63 specimens with CKD was compared with that of normal renal tissue(19 cases).Results Compared with the normal renal tissue,the expression of PAI-1 in CKD 1,2 and 3 stage wag respectively drastically increased(P<0.05).The expression of PAI-1 in CKD 3 stage was higher than that in CKD 1 and 2 stage(P<0.05).The expression of PAI-1 in the patients treated by valsartan[renal corpuscle(4.73±1.18)%,renal tubule(37.16±6.81)%]was lower than that with no treatment[renal corpuscle(5.81±1.95)%,renal tubule(43.22 ±10.25)%](P<0.05).Conclusions It suggests that the abnormal expression of PAI-1 in CKD play an important role in the progression of glomerular and tubulointerstitiai sclerosis in patients with CKD.ARB may prevent the development of renal inflammation and sclerosis by inhibiting the production of PAI-1.ARB may contribute to the prevention and therapy of CKD.

Objective To study the effect of Qingfei oral liquid contained serum on the transforming growth factor-?1 (TGF-?1) and platelet-derived growth factor-BB (PDGF-BB) mRNA gene expression of human embryonic lung fibroblast cells infected by adenovirus (ADV) type 3I and 7b. Method TGF-?1 and PDGF-BB mRNA expression of human embryonic lung fibroblast cells infected by ADV type 3I and 7b were determined by in situ hybridization before and after treated with Qingfei oral liquid contained serum. Results ADV could up-regulate TGF-?1 and PDGF-BB mRNA of human embryonic lung fibroblast cells (P

Reccent investigations demonstrated that genetically modified tumor cells could be used as vaccines against cancer. In this light, we introduced human interleukin -2 (IL-2) gene into a poorly immunogenic rat fibrosarcoma cell line WBT, a human lung abenocarcinoma cell line AGZY and a highly metastatie sub - cell line Anip973 derived from AGZY. The transduced cells showed no obvious changes in morphology, growth and colony - forming ability in soft agar.Transduction with IL-2 gene rendered the cells more sensitive than the parental cells and cells transduced with NeoR gene alone to the lysis by cytotoxic lymphocytes. High levels of IFN and TNF were detected in the supernatants of cocultured lymphocytes and tumor cells containing IL-2 gene. Tumorigenicity of WBT/IL-2 cells was greatly reduced in syngeneic rats. Metastatic capacity of Anip973 in nude mice was blocked by the transduction of IL-2 gene, but not the transduction of NeoR gene alone. Inoculation of WBT/IL-2 cells conferred rats resistance to the challenge of parental WBT cells.Splenocytes from WBT/IL-2-inoculated rats restimulated with WBT cells in vitro showed high CTL activity against WBT cells. Our results demonstrated the potential application of tumor cells transduced with IL— gene as active vaccine against cancer.

Objective To compare the efficacy of tramadol for patient-controlled intravenous versus provicial epidural analgesia (PCIA vs PCEA) and their effects on the T-lymphocyte subsets and natural killer (NK) cells during postoperative period in patients undergoing gynecological operation for tumor. Methods Thirty-nine ASA Ⅰ-Ⅱ patients aged 18-83 yr undergoing elective surgery for ovarian cancer or uterine cancer or myoma were randomly divided into two groups : PCIA group (n = 21) and PCEA group ( n = 18). Premedication consisted of intramuscular atropine 0.5 mg and phenobarbital 0.1 g. Operation was performed under epidural anesthesia. Epidural catheter was inserted at T12 -L1 approximately 3-4 cm into epidural space cephalad. The patients received a test dose of 2% lidocaine 5 ml. The first dose was 2% lidocaine 10-12 ml followed by 0.5% bupivacaine 5 ml every 45-60 min. Tramadol 100 mg was given iv in PCIA group or epidurally in PCEA group 15 min before the end of surgery. 100 ml of PCIA solution contained tramadol 800 mg (16 ml), haloperidol 5 mg (1 ml) and normal saline 83 ml and 100 ml of PCEA solution contained tramadol 400 mg (8 ml), haloperidol 5 mg (1 ml) and NS 91 ml. The PCA pump was set to deliver a background infusion at 2 ml?h-1 and a bolus dose 0.5 ml with lock-out interval of 15 min. Analgesia was assessed using VAS. Venous blood samples were taken for determination of T-lymphocyte subset (CD3+ , CD4+ , CD8+) and NK cell counts by flow cytometry the day before surgery and on 1st and 2nd postoperative day. Results The postoperative analgesia was satisfactory in both groups, and there was no significant difference in VAS scores between the two groups. No vomiting and respiratory depression were observed in both groups. The NK cell counts decreased significantly on the 1 st and 2nd postoperative day as compared with the preoperative value (P

BACKGROUND:Hemodialysis therapy is an important means for the treatment of acute renal failure, which aims to remove excess water and toxins and maintain acid-base balance of a patient, creating conditions for medication and nutrition therapy while avoiding multiple organ failure. OBJECTIVE:To compare bicarbonate-and lactate-buffered solutions for acute continuous hemodiafiltration in acute renal failure. METHODS:A computer-based search was performed in PubMed, EMBASE, SCI, Cochrane Library, Chinese Biomedical Literature Database, China Journal Ful Text Database, Chinese Medical Association Journals for randomized control trials related to bicarbonate-versus lactate-buffered solutions for hemodiafiltration in acute renal failure published before January 2014. The quality of the included studies was evaluated by Cochrane Handbook, and data were analyzed by RevMan 5.1 from the Cochrane Col aboration. RESULTS AND CONCLUSION:Four studies (171 patients) met inclusion criteria. Overal , patients treated with bicarbonate-buffered solutions had fewer cardiovascular complications and symptomatic hypotension events as wel as lower serum lactate levels than patients who received lactate-buffered solutions (P<0.05). There were no differences in mortality, serum bicarbonate levels, serum creatinine, serum pH, carbon dioxide partial pressure. The current evidence shows that patients undergoing bicarbonate-buffered solutions may experience fewer cardiovascular complications and symptomatic hypotension. Given the limited research, it is insufficient to recommend for clinical use.

Objective To study the effect of Interleukin-22 (IL-22) on murine asthmatic airway inflammation and airway remodeling, observe the effect of budesonide on IL-22 of asthmatic mouse model, explore the mechanism of budesonide in the treatment of asthma.Methods Ovalbumin(OVA) was used as an allergen to sensitize and challenge the mice.24 female specific-free (SPF) BALB/c mice aged four weeks were randomly divided into 3 groups:control group, asthma group and budesonide treatment group (BUD group).For Histopathological Examination, HE staining was used to measure the inflammation scores, AB-PAS staining was used to measure the hyperplasia of goblet cells and mucin.Enzyme-linked immunosorbent assay(ELISA) was used to analyze IL-22 levels in bronchoalveolar lavage fluid (BALF).Quantitative Real-time PCR was performed to analyze the effects of budesonide on IL-22 mRNA levels in lung tissue.Results The inflammation scores of asthma group were elevated compared with the control group.An overall change towards less severe asthmatic airway inflammation by the end of the trial was observed in the BUD group.IL-22 levels in BALF were significant decreased after the treatment of budesonide, the mRNA levels of IL-22 were obviously decreased in BUD group, too.A significant positive correlation was observed between the mRNA levels of IL-22 and airway inflammation.Conclusions The increasing IL-22 secretion can lead to the occurrence of airway inflammation of asthma.Budesonide can inhibit the expression of IL-22, thereby Budesonide could inhibit the development of airway inflammation of asthma.
