OBJECTIVE:To observe therapeutic efficacy and safety of recombinant human brain natriuretic peptide (rhBNP) in the treatment of acute decompensated heart failure (ADHF). METHODS:129 ADHF patients admitted in our hospital during Jul. 2013-Jul. 2015 were randomly divided into observation group(69 cases)and control group(60 cases). Control group was giv-en routine treatment. Observation group was additionally given rhBNP 1.5 μg/(kg·d)vein shock(d1),and then rhBNP 1 mg+5%Glucose injection 100 ml by 0.007 5 μg/(kg·min),ivgtt(d2-4). Treatment courses of 2 groups lasted for 7 d. Therapeutic efficacy and heart function indexes [left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVDd)] were observed in 2 groups as well as NT-proBNP level,medication fluid intake and urine volume 24 h after medication. The occurrence of ADR was observed. RESULTS:3 cases dropped out and 66 cases were included finally in doservation group. Total effective rate of AD-HF therapy in observation group (96.97%) was significantly higher than in control group (86.67%),with statistical significance (P<0.05). There was no statistical significance in LVEF,LVDd and NT-proBNP between 2 groups before treatment(P>0.05). Af-ter treatment,LVEF of 2 groups were increased significantly while LVDd were decreased significantly;LVEF of observation group [(42.3±3.6)%] was significantly higher than in control group[(37.9±3.3)%],while LVDd of observation group [(55.5± 3.6)%] was significantly lower than in control group[(61.3 ± 3.4)%]. NT-proBNP levels of 2 groups were decreased significant-ly,and the observation group [(1 389.5±29.6)pg/ml] was significantly lower than the control group [(2 778.0±26.8)pg/ml]. 24 h after medication,urine volume of 2 groups were significantly higher than medication fluid intake,and urine volume of observation group [(1 781.4 ± 89.7)ml] was significantly higher than that of control group [(1 372.6 ± 78.3)ml],with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between observation group (3.03%) and control group (5.00%),without statistical significance(P>0.05). CONCLUSIONS:rhBNP is significantly effective for ADHF,promotes heart function recovery and reduces renal function injury with good safety.

QTG also had an obvious inhibitory effect on early exudative auricular swelling induced by 2% compound croton oil and late proliferative granuloma induced by 2% agar. Conclusion QTG has an obvious effect for prostatitis. It can inhibit the early and late inflammation .

Purpose To investigate the diagnosis and differentail diagnosis of metastatic small cell carcinoma of bone in needle biopsy, especially for the differentail diagnosis with Ewing sarcoma of bone. Methods Clinicopathological informations of 11 cases of metastat-ic small cell carcinoma and 20 cases of Ewing sarcoma were collected, and markers for differentail diagnosis were detected in two groups by immunohistochemistry of EnVision. Results The positive rates of CD99 and FLI-1 were 27. 3% and 54. 5% in metastatic small cell carcinoma group, while the positive rate of CK was 15. 0% in Ewing sarcoma group. Patient′s age, single lesion, expression of CK, vimentin, CD99, FLI-1, CD56 were significantly different in two groups. Conclusions Metastatic small cell carcinoma and E-wing sarcoma share similar histopathologic features in needle biopsy, no single immunohistochemical marker can specifically distinguish small cell carcinoma from Ewing sarcouma. The correct diagnosis should comprehensive analyze clinicopathologic characters and a se-ries of immunohistochemical markers.

The acute phase of ischemic stroke patients are often treated with both Chinese patent medicine:and western medicine therapies in clinical practice. This research included 27,678 cases of the acute phase of ischemic stroke came from 14 3A level hospitals. We collected data from patients with ischemic stroke who used both Chinese patent medicine and western medicine and were hopitalized within 14 days from hospital information system (HIS). Constructing complex network of Chinese patent medicine and western medicine were found to show scale-free network. Hierarchical structure of the core algorithm was used to analyze the characteristics of combined core Chinese patent medicine and western medicine in admission condition of "acute", "critically", and "general" of ischemic stroke acute phase patient within one day, 2-3 days, 4-7 days and 8-14 days. We found that the core Chinese patent medicine mainly used for activate blood and resolve stasis medicine, and phlegm eliminating brain refreshing medicine in all kinds of patients, but the phlegm eliminating brain refreshing medicine were used to reduce with time elapsing. The core western medicine mainly used for anti-platelet medicine, improve circulation medicine, neuroprotective medicine, anticoagulants medicine and dehydration medicine. The dehydration medicine as the core western medicine for critically patients within 14 days, but the patients for general admission as core western medicine within 3 days. The neuroprotective medicine was used to decreases after 7 days in hospital. Combination of Chinese patent medicine and western medicine were mainly for neuroprotective medicine + activate blood and resolve stasis medicine, and anti-platelet medicine + activate blood and resolve stasis medicine, and improve circulation medicine + activate blood and resolve stasis medicine. The phlegm eliminating brain refreshing medicine was mainly combined with neuroprotective medicine by urgent and general admission condition patients, and it was more combined with dehydration medicine by critically admission condition patients. This research found that the dynamic characteristics for the combination of Chinese patent medicine and western medicine of acute phase of ischemic stroke patients by big data analytics and complex networks modeling, and provide basis for acute phase of ischemic stroke patients, it provide basis for ischemic stroke treatment strategy making.

Objective To investigate the influence of atosiban on the pregnancy outcome in patients with repeated implantation failure(RIF)in blastcyst thawed embryo transfer(bTET) Methods From January 2014 to December 2015,a total of 262 RIF patients undergoing bTET were retrospectively studied. They were divided into study group with a single bolus dose (6.75 mg/0.9 mL,iv) of atosiban before bTET (n = 94),and control groupwithout atosiban(n = 168). Results The clinical pregnancy rate(57.41%),implantation rate(38.41%) and living-birth rate(46.81%) of study group were significantly higher than those of control group (41.12%, 28.32% and 33.93% respectively;P < 0.05). Although the abortion rate of study group was higher than that of control group(14.82% vs 13.04%),both the ectopic pregnancy rate(3.70%) and the multiple pregnancy rate (16.67%) were lower than those of control group(5.79% and 17.39%),and there was no statistical difference (P > 0.05). Conclusion Atosiban treatment before embryo transfer may improve pregnancy outcomes of RIF patients in bTET.

Aim To construct 3 D structure model of cardiac Cav1.2 channel and check its accuracy and re-liability.Methods Homology model of Cav1.2 chan-nel α1 subunit was constructed using SWISS-MODEL server.The model was submitted to an online testing server built by University of California and scored by it.The binding of Cav1.2 channel with blocker or drug was simulated by MOE software molecular docking pro-gram to check the model′s accuracy and reliability.Re-sults Both the target sequence Cav1.2 α1 C and the template sequence Cav1.1 α1 S searched by SWISS-MODEL server belonged to L-type Ca2+channel.Since the homology was 7 1.5% revealed by sequence align-ment,homology modeling was performed using automa-ted mode.L-type Ca2+ channel blockers Verapamil, Nifedipine and Diltiazem could bind to the 3 D structure model of Cav1.2 channel,while sodium channel bloc-ker TTX could not.Furthermore,active ingredient of traditional Chinese drug Praeruptorin A and Berberine could also bind to the 3D structure model of Cav1.2 channel.Conclusion The 3 D structure model of Cav1.2 channel was constructed successfully,which provides reliable materials for further studies and estab-lishes the foundation for the application of homology modeling in the study of 3 D structure prediction of ion channels.

Objective To investigate the relationship between serum levels of adiponectin (APN) and retinol binding protein 4 (RBP4) in newly diagnosed type 2 diabetes mellitus (T2DM) patients. Methods 95 newly diagnosed T2DM patients and 55 non-diabetic volunteers from health examination population were studied. The serum concentrations of APN and RBP4 were determined by ELISA. The levels of plasma glucose, lipid profiles and insulin were also measured in fasting samples. Insulin sensitivity was assessed by insulin resistance index (HOMA-IR). The control group and diabetic group were divided into ≥60 years subgroup and <60 years subgroup respectively. According to the guideline designed by Chinese Diabetes Society(CDS)in 2004, the control group and diabetic group were divided into different kinds of abnormal metabolism groups. Results (1)The level of APN was significantly decreased in diabetic group compared with the control group[(7.26±4.69)mg/L vs. (11.93±4.89)mg/L], while the serum level of RBP4 in diabetic group was obviously higher than that in control group[(16.48±7.82) mg/L vs. (10.91±5.26) rag/L]. (2) The prevalence of metabolic syndrome in diabetic group was higher than that in control group (46.3% vs. 7.3%). (3)APN level was decreased with the increasing number of components of MS, and RBP4 level was increased with the increasing number of components of MS. (4) In DM group, APN level was correlated negatively with MS, waist circumference and BMI, and RBP4 level was correlated positively with waist circumference, HOMA-IR, BMI and TG. Conclusions APN and RBP4 levels are significantly associated with metabolic syndrome. Hypoadiponectinemia and higher retinal binding protein 4 may play an important role in the pathogenesis of MS.

Objective To explore different features and influencing factors of 75 g oral glucose tolerance test (OGTT) and glycated hemoglobin Ale (HbAlc) levels in subjects with newly diagnosed diabetes and prediabetes of natural history of type 2 diabetes. Methods All subjects were classified by OGTT into four groups: (1) normal glucose test (NGT), 31 subjects at age of (48. 4±15. 3) yrs (29-75 years old); (2) impaired fasting glucose (IFG), 33 subjects at age of (50. 8±9. 8) yrs (38-72years old) ; (3) impaired glucose tolerance test (IGT), 34 subjects at age of (54. 5±11.4) yrs (33-74years old), (4) T2DM, 117 subjects at age of (54.3 ± 14.1) yrs (29-75 years old). Glucose metabolism was evaluated by results of OGTT and HbAlc levels. The insulin secretion function and insulin resistance (IR) were evaluated by HOMA-β, △I30/△G330, area under curve of insulin (AUCINS)and HOMA-IR respectively. Results (1) Significant changes of HbAlc values among groups were as following order: T2DM(7. 41%)>IGT(5. 85%)>NGT(5.21%) (P<0. 01). HOMA-β value in T2DM, IGT and IFG decreased by 53. 1% (P<0. 01), 29.3% (P<0. 01) and 23.4% (P<0. 05)respectively as compared with NGT group. HOMA-IR value in diabetes group was 1.66-fold of NGT (P<0.01), 1. 29-fold of IFG (P<0.001) and 1.44-fold of IGT (P<0.05). (2) Only 3 h blood glucose concentration (BG) in 75 g OGTT was independently and positively correlated with HbAlc level (r=0. 71, P<0. 01). △I30/△G330 ratio was independently and negatively correlated with both 1 h and 2 h BG of OGTT (P<0.01). AUCins was positively correlated with only 3 h BG of OGTT (P<0.01). HOMA-β was independently and negatively correlated with all OGTT results except 2 h BG(P<0.01). HOMA-IR was an independently and negatively correlative factor of all OGTT results (P<0. 01 or P<0. 05). TG level was independently and positively correlated to only fasting BG (P<0. 05), and waist circumference value had an independent and positive relationship with only 1/2h BG (P<0. 01). Independently correlative factors of OGTT changes included △I30/△G330, AUCINS,HOMA-β, HOMA-IR and circumference values. Only 3 h BG was probably an independent contributor to HbAlc variation. Conclusions There are obvious HbAlc differences among T2DM,IGT and NGT patients. When HbAlc values are over 8%, no significant changes of glucose and insulin levels at 75 g glucose load test are found among subjects.

This study aimed to evaluate the influence of quartz fiber post placement on the fracture resistance of endodontically treated premolars with different dental defects under dynamic loading. Fifty extracted single-rooted mandibular premolars were randomized into five groups. Each group was prepared according to numbers of residual walls ranged from 0 to 4. Then each group was divided into two subgroups with one restored with quartz fiber posts and the other without posts. In no-post groups, gutta percha point 2 mm below cemento-enamel junction was removed. Composite resin was adapted to the well and used to shape the core directly. Each tooth was restored with a complete metal crown. Dynamic loading was carried out in a masticatory simulator with a nominal load of 50 N at 2 Hz for 300 000 loading cycles. Then a quasi-statically load was applied in a universal testing machine 30° to the long axis with a crosshead speed of 1 mm⋅min(-1) until fracture. Data were analyzed with one-way analysis of variance and pairwise comparison (P<0.05). No specimens failed during dynamic loading. The fracture resistance enhanced with the increase of numbers of coronal walls and the differences were significant (P<0.05). Placement of fiber posts had a significant effect when fewer than two walls remained (P<0.05), but it had no significant influence in groups with two, three or four walls (P>0.05). Fiber post did not change failure mode, and the fracture pattern was mainly favorable. More dentin walls need to be retained in clinic. When no less than two walls remained, a fiber post is not always necessary.
