Quality standard research of pieces of Chinese crude drugs is the important content of research of Chinese medicine processing, and it is also the key point of the whole standardization system of Chinese medicine. Although we have set up a preliminary quality standard system of pieces of Chinese crude drugs, it still under a low level. During the research of quality standard of pieces of Chinese crude drugs, we still face some problems, such as how to set up a more comprehensive, scientific, and reasonable quality standard. In this paper, we proposed some advices that we should pay more attention to traditional processing theories, processing mechanisms and effective substances during research of quality standard research of pieces of Chinese crude drugs.

Objective To determine the proportion and the clinical value of the thymus extending superiorly into the lower neck in children.Methods The MR images of 400 normal children were retrospectively reviewed.According to the childhood staging criteria.all children were divided into four groups:the infancy and toddlerhood group(0-3 yo,42),the pre-school age group(>3-6 yo,87),the school age group(>6-12 yo,168),and the adolescence group(>12-18 yo,103).The presence or absence of the superior extension of the thymus above the manubrium Was determined on sagittal T2-weighted images.If so,the distance between manubrium and thymic apex was measured.The associations between frequency of ccrvicaI extension and age and sex were evaluated using correlation analysis.Results Superior extension of the thymus was detected in 288(288/400,72.0%)children,with 39(39/42,92.9%)in the infancy and toddlerhood group,72(72/87,82.8%)in the pre-school age group,118(118/168,70.0%)in the school age group,and 59(59/103)in the adolescence group(57.3%).There Was a statistically significant relationship between age group and frequency of cervical extension of the thymus (X2=4.9684,P<0.05).There was no significant decreasing trend in the mean distance of cervical extension between age increasing groups(F=2.28,P>0.05).Conclusions Cervical extension of the thymus occurs in the majority of children,and should be considered as a normal finding.Through recognizing this finding,doctors can avoid misdiagnosing it as a pathologic mass.

BACKGROUND: With the development of nanotechnology, a new system for the delivery of drugs by magnetic nanovectors has been proposed. Within a magnetic field, the system can implement site-specific drug administration, thereby raising drug concentration at the lesion focus, elevate therapeutic effects, and reduce side effects.OBJECTIVE: To study the preparation of magnetic poly D, L-lactide-co-glycolic acid phenylarsine oxide nanoparticles (M-PLGA-PAO-NPs) and to evaluate characteristics of the prepared nanoparticles.DESIGN: Several factors influencing nanoparticle characteristics were selected for single-factor tests. Then, according to experimental results, and in conjunction with orthogonally designed statistics, the optimized prescription was obtained. SETTING: Department of Special Diagnosis, Changhai Hospital, Second Military Medical University of Chinese PLA.MATERIALS: The study was performed at the Department of Pharmaceutics, School of Pharmacy, Second Military Medical University of Chinese PLA from January 2005 to March 2006. The reagents used were as follows: phenylarsine oxide (Sigma, USA), poly D, L-lactic-co-glycolic acid (Shandong Medical Apparatus Institute, China), ferroso-ferric oxide (nanometer, Sigma, USA), polyvinyl alcohol (PVA1788, Beijing Organic Chemical Industry Plant, China). Methylene dichloride and other agents were all analytical grade and purchased from Shanghai Sinopharm Chemical Reagent Co., Ltd, China.METHODS: M-PLGA-PAO-NPs were prepared through an emulsion-evaporation process. Nanoparticle shape was observed by transmission electron microscopy. Magnetism was determined by a vibrating sample magnetometer. The size and diametral distribution of nanoparticles were determined by a laser particle size analyzer. The encapsulation ratio and drug loading of phenylarsine were measured by high performance liquid chromatography (HPLC). The percentage of phenylarsine oxide release in vitro was calculated [the percentage of phenylarsine oxide release in vitro =(total dose of phenylarsine oxide-residual dose of phenylarsine oxide)/ total dose of phenylarsine oxide].MAIN OUTCOME MEASURES: The shape, size, drug loading, encapsulation ratio and release in vitro of M-PLGA-PAO-NPs.RESULTS: The prepared nanoparticles had an average encapsulation ratio of 34.2%. Drug loading of 5 batches of nanoparticles was 3.06%, 3.15%, 3.18%, 3.21%, and 3.41%, respectively, with an average drug loading of 3.20%. Drug loading difference was small between batches, indicating good stability and reproducibility of the technology. M-PLGA-PAO-NPs were spherical, smooth, evenly distributed and non-adhesive. Ferrosoferric oxide microparticles, which exhibited unevenly dispersed black opacities, were found in the magnetic microparticles. Nanoparticles were in a narrow size range, with an average diameter of 290 nm (range 140-500 nm). When the magnitude and the direction of the outside magnetic field were changed, nanoparticles showed different intensities of magnetization. This indicated that M-PLGA-PAO-NPs had a certain magnetic response. The in vitro nanoparticle-release curve indicated that drug release was initially fast followed by a slow controlled release, and on day 8, it was basically stable.CONCLUSION:The experiment acquires a satisfactory technique for preparation of M-PLGA-PAO-NPs. The prepared M-PLGA-PAO-NPs were well targeted and exhibited slowly controlled drug release effects.

Objective To investigate the adjustment effect of microRNA-155 on CD4+CD25+ regulative T cell (Treg) in peripheral blood of sepsis patients,and to elucidate the role of miR-155 in the pathogenesis of sepsis.Methods A retrospective study was corducted.60 sepsis patients (mild n =20,moderate n=20,and severe n =20)from emergency room or intensive care unit (ICU) of the Fourth Hospital of Jiangsu University were enrolled.20 healthy volunteers were enrolled as controls.Real-time fluorescent quantitation polymerase chain reaction (qRT-PCR) was used to detect the levels of miR-155 and Foxp3 mRNA expressions in peripheral blood.CD4+CD25+ Treg cells in peripheral blood were identified by flow cytometry.Peripheral interleukin-10 (IL-10) was measured by enzyme-linked immunosorbent assay (ELISA).Results The expressions of miR-155,Treg,Foxp3 mRNA and the level of IL-10were higher in the patients with sepsis than those in healthy control group [Treg:(2.89 ± 1.13)％ vs.(2.32 ± 0.91)％,t=10.540,P=0.002; miR-155:1.19 ±0.48 vs.0.80 ±0.33,t=8.605,P=0.006; Foxp3 mRNA:0.18 ±0.08 vs.0.13 ±0.03,t=6.862,P=0.008; IL-10 (ng/L):56.89 ± 17.28 vs.33.24 ± 11.93,t=12.742,P=0.001].These variables were elevated gradually with the elevation of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ)score.The expressions of Treg,miR-155,Foxp3 mRNA and the level of IL-10 were (3.05 ± 1.21)％,1.36 ± 0.79,0.21 ±0.10,(62.82 ±21.38) ng/L in severe sepsis group; they were (2.86 ±0.88)％,1.25 ±0.56,0.17 ±0.08,(56.38 ± 19.65) ng/L in moderate group; they were (2.61 ± 0.87)％,0.94 ± 0.52,0.15 ± 0.05,(45.43 ± 14.40) ng/L in mild group.The values showed significant statistical difference among the mild,moderate and severe sepsis groups (all P＜0.01).Above values were significandy higher in non-survival group than those in survival group [Treg:(3.46 ±1.53)％ vs.(2.85 ± 1.03)％,t=14.250,P=0.005; miR-155:1.41 ±0.85 vs.1.16 ±0.76,t=11.875,P=0.006;Foxp3 mRNA:0.24 ± 0.11 vs.0.17 ± 0.09,t=8.795,P=0.001 ; IL-10 (ng/L):65.47 ± 23.58 vs.51.70 ± 16.86,t=16.313,P=0.001].The expression of miR-155 was positively correlated with the expression of CD4+CD25+ Treg and Foxp3 mRNA (r1=0.635,P1=0.007; r2=0.671,P2=0.005).Conclusion The result of this study suggest that miR-155 is involved in the cell proliferation regulation of CD4 +CD25 + Treg cells,and play some role in the immunological dissonance in sepsis.

Objective To explore the clinical effects of high frequency oscillatory ventilation (HFOV) combined with pulmonary surfactant (PS) on neonatal meconium aspiration syndrome (MAS).Methods Data of 53 newborns with MAS admitted into the Neonatal Intensive Care Unit of Ning Bo Women and Children's Hospital from June 2008 to June 2011 were retrospectively analyzed.According to different therapeutic measures,they were divided into three groups:conventional mechanical ventilation (CMV) group (n=23),HFOV group (n=18) and HFOV+PS group (n=12).The oxygen index,arterial oxygen/alveolar oxygen ratio (a/ApO2) and inspired oxygen fraction (FiO2) were monitored at 2,12,24 and 48 h after mechanical ventilation.The mechanical ventilation time,duration of hospital stay,change of symptom,complications and clinical outcomes of the three groups were compared by analysis of variance and Chi-square test.Results The parameters of the three groups at 2 and 48 h after mechanical ventilation were as followed:CMV group [oxygen index:(23.79±7.27) and (15.04±4.76) mm Hg; a/ApO2:0.11±0.04 and 0.31 ±0.07; FiO2:0.74±0.16 and 0.47± 0.21],HFOV group [oxygen index:(21.13±6.29) and (11.73±4.54) mm Hg; a/ApO2:0.14±0.06 and 0.35±0.06; FiO2:0.68±0.14 and 0.41±0.11] and HFOV+ PS group [oxygen index:( 18.35 ± 5.68 ) and ( 7.85 ± 5.06 )mm Hg; a/ApO2:0.17±0.03 and 0.40±0.02; FiO2:0.59±0.13 and 0.29±0.16].Compared with CMV group,the parameters of HFOV group and HFOV+ PS group were different at different time points,and the parameters (duration and extent) of HFOV+ PS group were better than those of HFOV group (all P＜0.05).The mechanical ventilation time was (7.2±0.6) days in CMV group,(4.2± 1.4) days in HFOV group and (2.9±0.5) days in HFOV+PS group; the hospital stay was (22.2±4.5) days in CMV group,(15.6±3.4) days in HFOV group and (11.8±4.3) days in HFOV+PS group; and the oxygen treatment time was (15.4± 2.4) days in CMV group,(11.8±5.3) days in HFOV group and (7.4±2.2) days in HFOV+PS group.The mechanical ventilation time,oxygen treatment time and hospital stay time were the longest in CMV group,the shortest in HFOV+ PS group (P＜ 0.05,respectively).Conclusions Early HFOV combined with PS might be a better therapeutic method for infants with MAS than HFOV or CMV alone.

Objective To evaluate the prophylactic effect of pancreatic duct stent (PPDS),NonSteroid Anti-Inflammtory Drugs (NSAIDs),and joint PPDS and NSAIDs on post endoscopic rectrograde cholangiopancreatography(ERCP) Pancreatitis(PEP) in choledocholithiasis patients.Methods A total of 200 choledocholithiasis patients were randomly divided into 4 groups,prophylactic pancreatic duct stent(PPDS) group (A),NSAIDs group (B),joint PPDS-NSAIDs group (C) and routine ERCP without prevention for PEP(group D).VAS score,levels of amylase in serum and CRP were measured before and 4 h,24 h,48 h after ERCP.Incidences of hyperamylasemia and PEP were observed.Results (1) Incidences of hyperamylasemia 48 h after ERCP were 6％ (3/50),6％ (3/50) and 4％ (2/50) in group A,group B and group C respectively,which were significantly lower than that of group D (11/55) (P ＜ 0.05).(2) Incidences of PEP 48 h after ERCP were both 2％ (1/50) in group A and group C,which were lower than that in group D (10％,5/50,P ＜ 0.05).Group B (4％,2/50) was lower than that of group D but there was no statistical significance(P ＞0.05).(3) VAS scores of all groups at 4 h,24 h and 48 h after the operation were significantly higher than before (P ＜ 0.05).Group B score was significantly lower than that of group D (P ＜ 0.05).Scores of group A and C at 4 h were lower than those of group D (P ＜ 0.05),and those at 24 h and 48 h were also lower but with no statistical significance (P ＞ 0.05).(4) Serum CRP levels at 4 h,24 h and 48 h were significantly higher than those before in each group.Serum CRP levels of group B and C were significantly lower than that of group D at 4 h,24 h and 48 h.Serum CRP level of group A was significantly lower than group D at 4 h,24 h.CRP level at 48 h of group A was lower than that of group D,but there was no statistical significance (P ＞ 0.05).Conclusion Both prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce incidence of hyperamylasemia after ERCP common bile duct lithotomy.Single or joint use of prophylactic pancreatic duct stent can prevent PEP.Furthermore,prophylactic pancreatic duct stent and NSAIDs (Parecoxib Sodium) can reduce pain and inflammation after ERCP common bile duct lithotomy.NSAIDs only (Parecoxib Sodium) is more effective than prophylactic pancreatic duct stent only and joint use of both.
