Pain and anxiety engender major psychic problems during all phases of treatment for burn patients. Analgesic alone does not allay these problems satisfactorily in these patients. Music therapy, as an important complementary and alternative therapy, has been widely used in multiple medical fields. However, its positive effect on alleviation of pain and anxiety in burn patients is undefined. The objective of this review is to summarize the feasibility, application fields, methods, and the effectiveness of music therapy in allaying pain and anxiety of burn patients during the whole course of treatment.

Objective To study the effects of Grape Procyanidins(GPC)on hemorheology in long distance runner.Method In vitro study: 22 long distance runners were divided into two groups randomly,the experimental group and control group.With ten days period,the experimental group was given GPC 200 mg per day;while the control group were given the capsule of starch 200 mg per day.In vivo study: the vein blood samples were taken from 5 long distance runners and every example was divided into five parts,and then treated with different concentrations of GPC or H2O2.Items of the hemorheology such as Er,HCT,Eb,Ep,PFC and VAI were tested both in vivo and vitro before and after the study.Results in vitro study: all items of the experimental group showed significant decline at then end of the study than those before the study.The contents of Er,Eb and Ep before the study(6.830?0.164,4.145?0.177,1.647?0.020,respectively) were significantly higher than those after the study(6.759?0.158,4.088?0.173,1.621?0.013,respectively)(P

Objective: To explore the advantage of RR-Lorenz plot (RR-LP) in analyzing the patients of sinus rhythm with long RR interval.
Methods: A total of 308 RR-LP patients with long RR interval were retrospectively studied. The patients were divided into 7 groups according to the type of long RR intervals. ① Sinus bradycardia with arrhythmia group, n=63,②Repeated transient sinus arrest group, n=16, ③Ⅱ° sino-atrial block group, n=14, ④Ⅱ° atrial ventricular block (Ⅱ° AVB) group, n=47, ⑤ Un-passed atrial premature beats (APB) group, n=28, ⑥ Atrial premature beats group, n=72 and ⑦ Premature ventricular beats group, n=68. We analyzed the patients of RR interval greater than 1500 ms with ambulatory electrocardiogram record.
Results: ①RR-LP of sinus bradycardia with arrhythmia group showed a single distributing area with 1500 ms for the origin of transverse and longitudinal axis with B line slope at 1, tilt angle of 45°.②RR-LP of repeated transient sinus arrest,Ⅱ° sino-atrial block,Ⅱ° AVB and APB groups showed special four distributing areas with B line slope at (0.51 ± 0.01), tilt angle of (23.04 ± 0.50) °, B line slope at 0.6, tilt angle of (27°), B line slope at (0.57 ± 0.21), tilt angle of (25.69 ± 9.59)° and B line slope at (0.50 ± 0.01), tilt angle of (22.59 ± 0.54) ° respectively.③RR-LP of premature beats groups showed special four regional distributing areas, B line slope for atrial premature beats was at (0.38 ± 0.12), tilt angle of (17.06 ± 5.22) ° and B line slope for ventricular premature beats was at (0.07 ± 0.05), tilt angle of (3.02 ± 2.39) °.
Conclusion: RR-LP in patients of sinus rhythm with long RR interval had speciifc morphology and distribution features, the local abnormality could be found in a plane via all RR intervals which provided a differential diagnosis for repeated occurrence of short RR interval.

This study examined the effects of ursolic acid (UA) on the proliferation and apoptosis of a human ovarian cancer cell line, CAOV3. The CAOV3 cells were cultured in the RPMI 1640 media and treated with different concentrations of UA (0, 10, 20, 40 mumol/L). The proliferation rate of the CAOV3 cells was determined by MTT assay. The apoptosis rate was measured by flow cytometry. ERK activity was detected by immunoprecipitation and the expressions of p-ERK1/2, MKP-1, Bax and Bcl-2 by Western blotting. The results showed that the proliferation rate was significantly decreased in the cells treated with UA as compared with that in the non-treated cells (P<0.05). The intracellular ERK activity and p-ERK1/2 expression were also reduced in the UA-treated cells, while the MKP-1 expression was elevated. Moreover, the apoptosis was found in the CAOV3 cells exposed to UA; the Bax expression was increased and the Bcl-2 expression decreased. The apoptosis rate in the UA-treated cells was much higher than that in the non-treated cells (P<0.05). It is concluded that UA can inhibit the proliferation of CAOV3 cells by suppressing the ERK activity and the expression of p-ERK1/2. And it can also induce the apoptosis of the CAOV3 cells by up-regulating the Bax expression and down-regulating the Bcl-2 expression.

Sauropunol A-D potentially with anti-inflammatory,anti-bacterial activities were recently isolated from traditional Chinese medicinal plant Sauropus rostratus.Herein,we report the total synthesis of sauropunol (A-D) starting from a commercially available 2-deoxy-D-arabino-hexopyranose.The trifluoromethane sulfonation of intermediates could simultaneously trigger intramolecular cyclization to afford 3,6-anhydro hexofuranoside scaffold.The following deprotection reaction could produce sauropunol A,B and C/D with total yields of 21％,5％,and 17％ (isomer sauropunol C/D),respectively.Structures of the target compounds were confirmed by comparison with NMR spectroscopic properties of those previously reported.

Objective To explore the correlation between wide QRS of transesophageal atrial pacing (TEAP) and implicit ventricular pre-excitation.Methods 77 patients tested by TEAP were divided into two groups according to the ECG results .45 patients in group Ⅰhad normal electrocardiogram .32 patients in group Ⅱhad ven-tricular pre-excitation.In group Ⅰ,TEAP results showed that electric pulse wave (S wave) was followed by intermit-tent or continuous wide QRS complex .At the same time , the results of group Ⅰ were compared with the results of groupⅡ.Results (1)The patients of group Ⅰwere excluded the presence of concealed accessory pathway by intra-cavitary electrocardiographic test,among them 20 patients (group ⅠA) were ventricular pacing,the test results dis-played that S wave was followed by wide QRS complex exhibiting a pattern of right bundle branch block ( RBBB) ,SR interval was 0 s;SR intervals of 25 patients (groupⅠB) were not fixed,SR interval was (0.07 ±0.01)s,S wave had no concern with QRS wave ,the wide QRS complex was premature ventricular contraction ,QRS wave shapes were dif-ferent according to the different sites of pacing origin .(2)In groupⅡ,the test results displayed that S wave was close-ly followed by the atrial depolarization wave P ,and there was a wide QRS complex with pre-excitation wave at the be-ginning after a atrioventricular conduction time shorter than normal ,SR interval was fixed ,SR interval was (0.08 ±0. 03)s,at the same time,different parts of accessory pathway QRS complex had different morphological characteristics . (3) SR interval of ⅠA group compared with groupⅠB and groupⅡ,the differences were statistically significant ( t=2.97,3.02,all P<0.05);SR interval had no statistically significant difference between group ⅠB and groupⅡ(t=2.66,P>0.05).Conclusion When TEAP displaying pacing wide QRS complex ,in order to avoid bringing misdiag-nosis,TEAP results should be analyzed comprehensively rather than blindly believing that the reason was concealed accessory pathway .

ObjectiveTo study of the impact on dose distribution by electron width of energy spectrum and angular distribution using Monte Carlo simulation.MethodsThe simulated electron energy spectrum and angular distributions was as the input parameters and percentage depth dose (PDD) and offaxis curves were simulated by a modified PENELOPE code package. Results PDD and off-axis dose distribution curves are almost the same and are not sensitive to energy spectrum width and angular distribution with the exception of energy spectrum width of 2.5 MeV with obviously different curves.ConclusionsIn the situation of clinical treatment,spectrum and angular distributions can be ignored when their width are not very large.It is helpful to save about 9％ time by using monoenergy beams in treatment planning system development.

Objective To analyze the misdiagnosis in extraovarian peritoneal carcinoma(EOPC). Methods The clinical manifestation, blood tumor marker, imaging examination, laparotomy, pathology, treatment and prognosis of 19 EOPC patients were retrospectively analyzed. Results The clinical symptoms were abdominal distention, abdominal pain and swelling. 17 cases were tested for blood CA-125 with 15 at abnormaly high level, and in 4 cases ascites was CA-125 positive ( ＞ 10 KU/L). Tumor cells were detected in the ascites in 12 cases. Three cases were misdiagnosed as of uterine origin, 13 cases misdiagnosed as adnexal tumor, 1 case was misdiagnosed as bladder and intestinal tumor. Only 2 cases were correctly diagnosed before the operation. All of the cases were pathologically proved as peritoneal carcinoma. The five-year survival rate was only 20 percent. Conclusions Abdominal distention and pain with unknown causes were the primary manifestations of EOPC, elaborate physical examination sometimes may provide with important information. The significant elevation of serum CA-125 and the ascites cytology may be helpul for the differential diagnosis of PPC. CT scan is valuable for the diagnosis of EOPC.

To produce specific antibodies against malachite green ( MG) , one special hapten was synthesized and characterized, and conjugated to carrier protein as immunogen. The immunogen showed excellent reactogenicity and immunogenicity. One specific monoclonal antibody (mAb, named MG-DA4-C7) with high sensitivity and specificity for MG in indirect competitive enzyme-linked immunoassay ( icELISA ) was screened. The isotype was IgG1 and the light chain was κ type. After optimization of ELISA conditions, the proposed icELISA showed a 50% inhibition value ( IC50 ) of 0. 96 μg/L, a linear range ( IC20-IC80 ) of 0. 1-8. 1 μg/L and a limit of detection ( LOD, IC10 ) of 0. 05 μg/L for determination of MG. The assay showed cross-reactivity of 18. 1%, 26. 5% with crystal violet and brilliant green, respectively, and negligible cross-reactivity with other metabolites of MG (<0 . 1%) . The average recoveries of MG from spiked fish samples were from 87. 3% to 107. 3%. Good correlation (R2=0. 999) was obtained between the results of icELISA and those of liquid chromatography-tandem mass spectrometry analysis. The proposed icELISA is suitable for the determination of MG in fish samples in a simple and sensitive manner.
