Medical Journal of Chinese People's Liberation Army 2016;41(6):500-503
Objective To observe surgical outcome of reoperation for paravalvular leakage and medium- and long-term survival. Methods The clinical data of 28 patients receiving reoperation for paravalvular leak (PVL) in General Hospital of PLA between October 1998 and October 2015. The patients included 22 males and 6 females, with a mean age of 55.3 years (ranging from 15-67 years). PVL was reported in 18 cases after mitral valve replacement, in 4 after aortic valve replacement, in 4 after multiple valve replacement (mitral PVL), in 1 case after multiple valve replacement (multiple PVL) and in 1 after radical surgery for trilogy of Fallot with tricuspid valve replacement (tricuspid PVL). There were 2 cases diagnosed as infective endocarditis contributing to PVL. The grades of heart function were NYHA II in 11 patients, NYHA III in 10, NYHA IV in 7. Results Two patients died in hospital because of septic shock and MODS respectively. One patient developed hypoxic-ischemic encephalopathy after operation. There were 2 patients undergoing second thoracotomy on account of drainage post-operatively. One patient suffered recurrence of PVL. Twenty-two out of 26 patients were followed-up for 12 to 219 months (average 76.21 months) and 4 were lost to follow-up. One patient died of severe pancreatitis 31 months after hospital discharge and 1 had recurrence of PVL with heart function NYHA III. Twenty-four survivals are in NYHA class II. Conclusion Aggressive operation is effective treatment for moderate-severe PVL diagnosed by cardiac ultrasonography.

The antitussive activity assay for the root extraction of Disporum cantoniense was carried out with coughing mice induced by ammonia liquor. The results showed that the ethanol and water extractions of D. cantoniense possess strong antitussive activity, and the high dose of the former was better than positive control, and then the constituents of the ethanol extraction were separated and purified by various modern chromatographic techniques. Their structures were identified by physico-chemical properties and spectroscopic data. As a result, eight compounds were isolated and identified as stigmast-4-en-3-one(1), (22E, 24R)-ergosta-5, 7, 22-trien-3beta-ol(2), obtucarbamate A(3), obtucarbamate B(4), neotigogenin(5), azo-2, 2'-bis[Z-(2,3-dihydroxy-4-methyl-5-methoxy) phenyl ethylene] (6),dimethyl {[carbonylbis (azanediyl)] bis( 2-methyl-5, 1-phenylene) j dicarbamate (7) , and quercetin-3-O-pB-D-glucopyranoside(8). All compounds were isolated from this plant for the first time, and the result of bioactivity-directed isolation showed that compounds 3, 4, and 6 had obvious effect on antitussive activity, and compound 6 had the same level as positive control.

BACKGROUND: The present study was undertaken to examine the regulatory effect of hydrogen sulfide (H2S) on endoplasmic reticulum stress in alveolar epithelial cells of rats with acute lung injury (ALI) induced by oleic acid (OA). METHODS: Seventy-two male Sprague Dawley (SD) rats were divided into control group, oleic acid-induced ALI group (OA group), oleic acid-induced ALI with sodium hydrosulfide (NaHS) pretreatment group (OA+NaHS group), and sodium hydrosulfide treatment group (NaHS group). Rats of each group were further subdivided into 3 subgroups. Index of quantitative assessment of histological lung injury (IQA), wet/dry weight ratio (W/D) and H2S level of lung tissues were measured. The expressions of endoplasmic reticulum stress markers including glucose-regulated protein 78 (GRP78) and α-subunit of eukaryotic translation initiation factor-2 (elF2α) in lung tissues were measured by immunohistochemical staining and Western blotting. RESULTS: The IQA score and W/D ratio of lung tissues at the three time points significantly increased in rats injected with OA, but significantly decreased in other rats injected with OA and NaHS. The level of H2S in lung tissue at the three time points significantly decreased in rats injected with OA, but significantly increased in other rats injected with both OA and NaHS. GRP78 and elF2αdecreased in rats injected with OA, but increased in other rats injected with both OA and NaHS, especially at 4-hour and 6-hour time points. CONCLUSION: The results suggested that H2S could promote alveolar epithelial cell endoplasmic reticulum stress in rats with ALI.

Objective To assess the efficacy and safety of topical tacrolimus for erosive oral lichen planus (EOLP). Methods Literatures published up to December 2013 were searched from PubMed, Embase, CENTRAL, Chinese BioMedical Literature Database (CBM), and System for Information on Grey Literature in Europe (SIGLE). All randomized controlled trials (RCTs) of topical tacrolimus for EOLP which compared with other interventions or a placebo were considered in this Meta-analysis. Two researchers collected data independently. The assessment of methodological quality was based on Cochrane Handbook and the materials were analyzed with the software Revman 5.2.5. The primary outcome measures were the symptoms (e.g. pain, discomfort) complained by patients. The secondary outcome measures included the improvement rate of clinical signs assessed by the investigators and the incidence of adverse effects (e.g. clinical candidiasis). Results A total of 9 RCTs involving 476 patients were finally included. The pooled odds ratio (OR) of clinical improvement for topical tacrolimusvs. topical corticosteroids was 1.19 [95% confidence interval (CI): 0.64-2.22,I2: 44%]. Regarding to 0.1% tacrolimus and 0.03% tacrolimus, the pooledOR were 1.87 (95 %CI: 0.60-5.82) and 1.47 (95 %CI: 0.14-16.04) respectively in subgroup analysis. No serious adverse events were reported in topical tacrolimus group. Conclusions There was no evidence to support that topical tacrolimus for EOLP was more effective and safer than topical corticosteroids in this Meta-analysis. Clinical assessment criteria should be established and accepted by clinicians and researchers before further RCTs are undertaken.

Aim: To study the effect of diabetes mellitus and insulin treatment on rat penile nitric oxide synthase content.Methods: Male Wistar rats were divided at random into two groups: the Control ( n = 8) and the Diabetic ( n =17). Diabetes mellitus was induced by intraperitoneal injection of streptozotocin. The diabetic animals were then ran domly divided into two subgroups: diabetic rats without insulin treatment ( n = 7) and diabetic rats with insulin treat ment ( n = 10). The neuronal nitric oxide synthase (nNOS) in the penile corpus cavemosum were assayed by immrmo histochemical staining with specific antibody to nNOS and the nNOS-positive nerve fibers were counted semiquantita tively under a high power microscope. Results: The nNOS- positive nerve fibres in diabetic rats with treatment was higher than that in diabetic rats without treatment ( P < 0.05) and lower than that in the controls ( P < 0.01 ). The nNOS-positive nerve fibres in diabetic rat without treatment were also lower than that in the controls ( P < 0.01). Con clusion: In streptozotocin-induced diabetic rats, the nNOS content in the penile corpus cavernosum was significantly decre~ed. Insulin treatment at the dose level employed partially restores the penile nNOS content in these rats.

Objective To observe the effects of arsenic trioxide (ATO) on apoptosis of human fibrob- last-like synoviocytes of rheumatoid arthritis (HFLS-RA) and to study the mechanism.Methods HFLS-RA were cultured with standard medium as control group or with mediums supplemented with 0.5,2,8?mol/L ATO respectively.The apoptosis of HFLS-RA cultured for 72 h with different concentrations of ATO were in- vestigated under electron microscope.Apoptosis exponent was measured by terminal deoxynucleotidyl transf erase-mediated dUTP nick-end labeling (TUNEL).To detect the proliferation of HFLS-RA euhured with ATO,MTr assay were carded out in 5 consecutive days.Moreover,the NF-kB mRNA level of HFLS-RA was measured by RT-PCR after treated with ATO for 24 h.Results ATO induced the apoptosis of HFLS-RA. Apoptosis exponent was increased in a dose dependent manner in TUNEL experiment,especially in the cells treated with 2 and 8?mol/L ATO (P<0.05).HFLS-RA proliferation was inhibited in both dose and time de- pendent manner when cultured with ATO.Meanwhile,the NF-kB mRNA level was decreased in ATO treated groups,which was especially significant in mediums cultured in higher than 2?mol/L ATO (P<0.05).Con- clusion ATO depresses the proliferation of HFLS-RA and may increase the apoptosis by decreasing the ex- pression of NF-kB mRNA.These findings suggest that ATO have the potential to be a novel therapeutic agents for rheumatoid arthritis.
