Objective To study the effect of batroxobin combined with Yinxingdamo injection on serum endothelin(ET),nitric oxide(NO),superoxide dismutase(SOD),vascular cell adhesion molecule-1(VEGF-1)in patients with sudden deafness(SVCAM-1),to explore the best treatment for patients with sudden deafness.Methods Ninety patients with sudden deafness from June 2014 to June 2015 were recruited as the subjects of this study.The patients in control group were treated with batroxobin and batroxobin and ginkgo dipyridol.The levels of serum ET,NO,SOD,sVCAM-1,time of symptom recovery and the curative effect were observed.Results After treatment,the levels of ET,NO and sVCAM-1 in the observation group were significantly lower than those in the control group [(64.28±5.72)pg/mL vs(67.36±6.31)pg/mL,(43.08±9.53)μmol/(93.24±11.25)NU/mL](P<0.05).The results showed that there was no significant difference between the two groups.The recovery time of tinnitus,auria and vertigo in the observation group were less than those in the control group [(3.86±1.02)d vs(5.97±1.34),(5.03±1.24)d vs(7.37±2.01)d,(8.09±2.10)d vs 9.07±2.37)d](P<0.05).The total effective rate in the observation group was better than that in the control group(93.33％vs 75.55％,P<0.05).Conclusion Batroxobin combined with ginkgo dipyridolum injection can decrease the level of ET,NO and sVCAM-1,improve the level of SOD,and improve the microcirculation of the inner ear.Compared with the single effect of Batroxobin More desirable,worthy of promotion.

Objective To explore the therapeutic effects of statin in patients with chronic obstructive pulmonary disease (COPD) in stable period. Methods 83 patients with COPD in stable period were recruited and randomly divided into two groups, treatment group (n = 41) and control group (n = 42).The control group received conventional routine therapy, and treatment group was given rosuvastatin calcium 20 mg once per day on the basis of routine treatment. The levels of sera C-reactive protein (CRP), pulmonary function (FEV1、FEVl%pred), and COPD assessment test (CAT) were observed at the time points of 0 week and 12th week, 24th week and 48th week were compared between two groups. Results At 12th week after the treatment, sera CRP levels, FEV1, FEV1%pred and CAT scores in either control group or treatment group showed some extent of improvements as compared to those at the time point of 0 week, and there was statistical difference of sera CRP levels and CAT scores between two groups (P < 0.05). There was no statistical difference of FEV1, FEV1%pred between two groups (P > 0.05) .24th week and 48th week after the treatment; sera CRP levels, FEV, FEV1%pred and CAT scores in two groups all significantly improved and were statistical different between two groups (P < 0.05). Conclusion Statin can alleviate inflammatory reaction, improve pulmonary function and life quality of patients with COPD.

Objective To investigate the effects of continuous positive airway pressure (CPAP) on the levels of hemorheology and C-reactive protein in patients with obstructive sleep hypopnea apnea syndrome (OSAHS). Methods 58 moderate to severe OSAHS subjects were selected as treatment group and 32 healthyadults were selected as control group. Hemorheology and C-reactive protein in all subjects were examined and compared. The levels of hemorheology and C-reactive protein were also examined and compared before and after 3 months CPAP treatment in treatment group. Results In treatment group, the levels of the whole blood viscosity and hs-CRP were significantly higher than those in control group (P < 0.01). After treatment of CPAP for three months, the levels of the whole blood viscosity and hs-CRP obviously decreased (P < 0.01). Conclusion Levels of hemorheology and hs-CRP are elevated in patients with OSAHS and CPAP therapy could effectively decrease serum levels of hemorheology and hs-CRP in patients with OSAHS.

Objective To investigate changes in number of endothelial progenitor cells(EPCs)from bone marrow and circulation in mice with acute pancreatitis.Methods BALB/c mice were assigned randomly to saline group and cerulein group.Animals were sacrificed at 12, 24 and 48 hours after injection.Bone marrow and circulating EPCs were detected by flow cyzometric analysis.Plasma VEGF, TNF-α and ET-1 were determined by enzyme-linked immunosorbent assay.The expression of VEGF in the pancreas was assessed by Western blotting.Apoptosis in situ was detected by TUNEL.Results The amounts of EPCs in bone marrow and circulation increased remarkably after cerulein injection(P < 0.05), also the levels of plasma VEGF TNF-α and ET-1(P < 0.05), the EPCs levels in bone marrow and circulation seen in the study closely mirrors the levels of VEGF detected in the circulation(r = 0.77, 0.67 individually).VEGF expression in pancreas was up-regulated after 12 h of cerulein injection compared with that of control group.Apoptosis of endothelial cells also increased in the cerulein group.Conclusion EPCs were mobilized by acute pancreatitis, which may be due to the mobilizing effect of increased levels of VEGF, EPCs may participate in the repair process of injured endothelium induced by acute pancreatitis.

BACKGROUNDTo investigate the relationship between cytokine level and cancer cachexia on murine model, and to observe the effects of regular dose of indomethacin on cancer cachexia and survival of mice.

METHODSC57 mice bearing Lewis lung carcinoma were used to establish murine cancer cachexia model. The serum cytokine levels (IL-1, IL-6, TNF-α and IFN-γ) and body weight of the mice were measured at different time points before and after treatment with daily intraperioneal injection of either indomethacin (1 mg/kg) or saline.

RESULTSThe mice in cancer cachexia group had significantly higher serum levels of IL-1, IL-6 and TNF-α ( P < 0.05) and lower body weight ( P < 0.05) than those in healthy control group. Compared to saline treatment, indomethacin intervention apparently down regulated the levels of IL-1, IL-6 and TNF-α ( P < 0.05 ), and remarkably prolonged the survival of mice ( P < 0.05). No significant difference in IFN-γ level was observed between cancer cachexia and healthy control groups ( P > 0.05), as well as between indomethacin and saline groups ( P > 0.05).

CONCLUSIONSThe results suggest that serum IL-1, IL-6 and TNF-α are possibly associated with cancer cachexia, however, IFN-γ seems to be irrelevant. Indomethacin may potentially ameliorate cancer cachexia through down-regulating levels of cytokines.

A 10-year-old boy presented with a 3-year history of erythematous flat keratotic papules and brown-yellow, nail-like prominent keratotic plaques all over the body surface. Dermatological examination showed verrucous or nail-like prominence over multiple erythematous keratotic plaques on the head, face,trunk and limbs. The lesions, most of which confluenced, were covered with brown-yellow and greasy crusts,and gave a porcupine-like appearance. Skin biopsy of lesions from the back revealed epidermal hyperkeratosis,focal columnar parakeratosis, acanthosis, few acantholytic and dyskeratotic cells in stratum corneum, irregular upward proliferation of dermal papilla cells, and a superficial perivascular lymphocytic infiltration. A diagnosis of ichthyosis hystrix was established based on the histopathological findings. The boy was treated with oral acitretin and topical 0.1% acitretin cream for 8 years. The initial and maximum dose of oral acitretin was 0.5 mg·kg-1·d-1 and 1 mg·kg-1·d-1, respectively. Liver and kidney function, body height and weight were examined during the treatment, and no side effect was observed except for skin xerosis.

Objective To evaluate the value of serum procalcitonin(PCT)on antibiotics use in treatment of acute exacerbations of chronic obstructive pulmonary disease( AECOPD). Method From May 2004 to December 2006, a total of 235 patients requiring hospitalization for AECOPD were randomly assigned into two groups: standard therapy group(group A, n = 117)and PCT-guided group(group B, n = 118) .PCT levels of all patients were measured after hospital admission by an amplified cryptate emission technology assay. On the base of similarly normal treatment, group A received antibiotics according to the attending physicians,and group B were treated with antibiotics according to serum PCT levels:antibiotic treatment was applied with PCT level ≥0.25 ng/ml and was discouraged with PCT level ＜0.25 ng/ml. Length of hospitalization,clinical efficacy,costs of hospitalization and antibiotics, rate of antibiotics use, hospital mortality,rate of exacerbation and rehospitalization within 1 year were observed. Analyses were performed by t test, Mann-Whitney U test or χ2 test. Results Clinical efficacy, hospital mortality, length of hospitalization, rate of exacerbation and rehospitalization within 1 year were similar in two groups (P =0.635,0.768,0.884,0.747,0.727) ;costs of antibiotics and hospitalization,rate of antibiotics use of PCT-guided group were lower than that of standard therapy group( P = 0.029,0.036,0.014). Conclusions PCT could be used in treatment of AECOPD for antibiotic use after hospital admission,which may reduce antibiotic use and lower costs of antibiotic and hospitalization.

Objective To explore the clinical features and causes of misdiagnosis of the patients with acquired deficiency of vitamin K-dependent coagulation factors (ADVKDCF). Methods Retrospective analysis was performed with the data from 62 patients with ADVKDCF for etiological factors, clinical manifestations,laboratory examinations, diagnosis and treatments. Results Among the 62 patients, 51 patients were with unknown causes( subgroup A) and 11 were with clear histories of anticoagulant rodenticide poisoning( subgroup B). The presentations of hemorrhage of the patients varied with hematuria as the most common first symptom,followed by skin, mucosa, muscle, internal organs bleeding (28/62). The most common hemorrhage symptom is hematuria. 35 of the 62 patients had hemoglobin(Hb) levels less than 100 g/L due to blood loss( the lowest level was 32 g/L). Thirty-eight patients were misdiagnosed at the first visit and the median time from hemorrhage manifestation to definite diagnosis was 8 days (range,2 to 192 days). ADVKDCF was mostly misdiagnosed as the urinary system diseases (23/38), followed by hemophilia (8/38). Laboratory examinations showed normal platelet count , throm bin time (TT) and normal fibrinogen(Fg) concentration, but prolonged plasma prothrombin time (PT), activated partial prothrombin time (APTT) and international normalized ration (INR). All of patients received high dose vitamin K ( intravenous vitamin K1 with a initial dose of 20 to 240 mg/d and then oral vitamin K4 maintenance) . The bleeding symptoms disappeared 1 day after treatment and the Hb levels increased dramatically. There were significant differences in PT, APTT and INR of the patients before and after treatment( P ＜0. 01 ). Followed by a median follow - up of 8 months , no patient had severe adverse effects or recurrence. Conclusion The hemorrhage presentations of the patients with ADVKDCF are various. The most common hemorrhage symptom is hematuria. The misdiagnosis rate of ADVKDCF is high with urinary systems disorders as the most common misdiagnosis. Sequential treatment with vitamin K is an effective and safe method to prevent recurrence. Early detection of coagulation function is helpful to reduce misdiagnosis possibility.

Objective: The aim of the study was to evaluate the changes and outcome of kidney function after catheter ablation in patients with persistent atrial fibrillation (PAF). Methods: A total of 146 patients with PAF underwent primary atrial fibrillation (AF) ablation were enrolled from January 2013 to December 2014 and followed up. The subjects were divided into the AF recurrence and AF non recurrence groups. The estimated glomerular filtration rate (eGFR) was calculated and serum creatinine levels were detected before ablation and during follow-up. Renal failure was defined as ≥ 25% decline in eGFR. Kaplan-Meier survival curves was applied for the incidence of renal failure. Cox proportional hazards models were conducted to assess the relationship between recurrence of AF and renal failure. Results: After (16.3±11.8) months of follow-up, the eGFR in patients with no recurrence of AF was higher than that in patients with recurrence. eGFR and ΔeGFR in patients with no AF recurrence differed significantly from those in patients with recurrence [(114.15±18.24) ml·min^-1·1.73m^-2 vs. (98.64±24.09) ml·min^-1·1.73m^-2, and (7.42±6.36) ml·min^-1·1.73m^-2 vs. (-11.40±10.19) ml·min^-1·1.73m^-2, all P<0.001]. The incidence of the renal failure was significantly lower (4.41% vs. 16.67%, P<0.05) and the survival prognosis was significantly better in patients with no recurrence than those in patients with recurrence (χ²=5.965, log-rank P=0.05). The multivariate Cox regression analysis revealed that age, baseline eGFR, recurrences of AF and diabetes were independent predictors of the renal failure, with the HR 1.152, 1.086, 13.442 and 6.076, respectively. Conclusions PAF patients with no recurrence after ablation had a better renal function than those with recurrence, and the recurrence of AF is associated with the deterioration of kidney function in patients with PAF.
