AIM To explore the effect of hypoxia on apoptosis in human umbilical vein endothelial cells(HUVECs) and the role of ecdysterone(EDS)in inhibition of apoptosis. METHODS ① Culture and identification of HUVECs;② Hypoxic model(0,12,24,48 h) in HUVECs was established. While HUVECs was incubated 24 h with EDS(100 mg?L -1 ) under hypoxic condition. Apoptosis in HUVECs was detected by TUNEL;③ HUVECs received EDS 100 mg?L -1 in normal and hypoxic condition. After 24 h, vascular endothelial growth factor (VEGF) was detected with immunohistochemical technique. RESULTS The apoptosis percentages are different under different hypoxic condition. The longer hypotic the time was, the higher the apoptosis percentage was. EDS reduced apoptosis of HUVECs. EDS could enhance expression of VEGF protein in cardiac myocytes of rat in normal and hypoxic condition. CONCLUSION The role of hypoxia in HUVECs apoptosis is more significant along with prolonging of hypoxic time. VEGF play an important role in protective effect of EDS on endothelial cell apoptosis.

Objective To observe the estrogenic activity of octylphenol(OP) in vitro and to conduct a preliminary study of its mechanism. Methods The estrogenic activity of OP was detected by cell proliferation test of MCF 7 cells in vitro and the mechanism was preliminarily studied by growth curve analysis, cell cycle analysis, tamoxifen(Tam) antagonistic test and apoptosis detection. Results OP was found to have estrogenic activity to stimulate the proliferation of MCF 7 cells. Cell cycle analysis revealed that the cell proliferation indexes of OP and 17? estradiol(E 2) were higher than those of alcohol. The estrogenic activities of OP and E 2 to stimulate the proliferation of MCR 7 could be antagonized by Tam. Both OP and E 2 could inhibit the cell apoptosis of MCF 7 cells. Conclusion OP possesses estrogenic activity to stimulate the proliferation of MCF 7 cells. The mechanism may be due to binding to the estrogen receptor, which may have effect on cell proliferation and apoptosis.

0.05).Conclusions Both CBZ and OXC are effecive in treating typical frontal lobe seizures.

Objective To compare adductor canal block(ACB)with topical anesthesia for postoperative analgesia in the patients undergoing arthroscopic knee surgery.Methods Sixty patients of both sexes,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status ⅠorⅡ,scheduled for elective arthroscopic meniscectomy,were divided into 2 groups (n=30 each) using a random number table:ACB group and topical anesthesia group(TA group).In group ACB,0.2% ropivacaine 20 ml was injected into the adductor canal under the guidance of ultrasound at 30 min before operation to perform ACB.In group TA,0.25% ropivacaine 20 ml was injected into the articular cavity at 5 min before the end of operation.The development of effective analgesia (VAS scores ≤4)and weakened quadriceps femoris muscle strength(muscle strength 0-2 grade,post-operative muscle strength was assessed by using manual muscle testing),related complications(local anesthetic intoxication,bleeding at the puncture site and hematoma) and occurrence of postoperative nausea,vomiting and delayed emergence were recorded.Results Compared with group TA,the rate of effective analgesia within 12 h after surgery was significantly increased (P<0.01),and no significant change was found in the incidence of weakened quadriceps femoris muscle strength,nausea and vomiting in group ACB(P>0.05).Local anesthetic intoxication,bleeding at the puncture site,hematoma or delayed emergence was not observed in the two groups.Conclusion ACB produces better efficacy for postoperative analgesia than topical anesthesia in the patients undergoing arthroscopic knee surgery.

Objective: To prove the clinical therapeutic effect of acute and chronic bronchial asthma with Chuankezhi(CKZ) Injection. Methods: 40 cases of bronchial asthma, including inpatients and outpatients were selected, divided into the attack period group (20) and the relief period group (20). The former was intramuscularly injected CKZ injection 4mL, twice a day, 14 days being a course of treatment. The latter was intramuscularly injected CKZ injection 4mL, twice a day for 15～30 days and 2mL, every other day for 31～90 days; 90 days being a course of treatment. The symptoms and signs, such as asthma, cough, expectroation, pulmonary wheeze were observed. and pulmonary function, absolute eosinophilic granulocyte count and immunogobulin E were measured before and after treatment. Result: By the use of CKZ injection to treat bronchial asthma, the total effective rate amounted to 85% and obvious difference before and after treatment in the two groups ( P

Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.

OBJECTIVETo observe the effect of Bushen Huoxue Recipe (BHR) on inhibiting vascular calcification (VC) in chronic renal failure (CRF) rats by regulating BMP-2/Runx2/Osterix signal pathway, and to explore its possible mechanism.

METHODSThirty SD rats were randomly divided into the normal group, the model group, and the BHR group, 10 in each group. Rats in the model group and the BHR group were administered with 250 mg/kg adenine suspension by gastroagavage and fed with 1.8% high phosphorus forage, once per day in the first 4 weeks, and then gastric administration of adenine suspension was changed to once per two days in the following 5-8 weeks. Rats in the BHR group were administered with BHR at the daily dose of 55 g/kg by gastrogavage in the first 8 weeks, once per day. Equal volume of normal saline was given to rats in the normal group by gastrogavage for 8 weeks. Histological changes in renal tissue and aorta VC were observed by HE staining and alizarin red staining respectively. Levels of calcium (Ca), phosphorus (P), serum creatinine (Cr), blood urea nitrogen (BUN), and intact parathyroid hormone (iPTH) in serum were detected. Protein expression levels of bone morphogenetic protein (BMP-2), Runt related transcription factor (Runx2) , and Osterix were detected by Western blot.

RESULTSHE staining showed that compared with the normal group, disordered glomerular structure, tubular ectasia and dropsy, intracavitary inflammatory cell infiltration, dark brown crystal deposition in kidney tubules, renal interstitial fibrosis, and decreased number of renal blood vessels in the model group. Compared with the model group, normal glomerular numbers increased more, reduced degree of tubular ectasia, decreased number of inflammatory cells, and reduced adenine crystal deposition in the BHR group. Alizarin red staining showed that compared with the normal group, calcified nodes could be found in the model group, with extensive deposition of red particle in aorta. Compared with the model group, calcified nodes were reduced in the BHR group. Compared with normal group, serum levels of P, SCr, BUN, and iPTH significantly increased, serum Ca level significantly decreased, protein expressions of BMP-2, Runx2, Osterix also increased in the model group (P < 0.05, P < 0.01). Compared with the model group, serum levels of P, SCr, BUN, and iPTH levels significantly decreased, serum Ca level significantly increased, protein expressions of BMP-2, Runx2, Osterix also decreased in the BHD group (P < 0.05, P < 0.01).

CONCLUSIONBHD could improve renal function, Ca-P metabolism, and renal histological changes in CHF rats, down-regulate the expression level of BMP-2/Runx2/Osterix signal pathway in vascular calcification of CRF, which might be one of the mechanisms for inhibiting VC in CHF.
