OBJECTIVE:To observe the effect of acyclovir on neurological function and cytokines of children with viral menin-gitis. METHODS:Totally 70 children with viral meningitis were randomly divided into control group and observation group. All children were given routine treatment,including defervescence,reducing intracranial pressure and regulating water and electrolyte balance,etc. Based on it,the control group was treated by Ribavirin glucose injection 15 mg/kg,iv,bid;observation group was treated by Acyclovir glucose injection 5 mg/kg,iv,tid. The course for both was 7 d. The clinical data was compared,including the vascular endothelial growth factor (VEGF),matrix metalloproteinase-9 (MMP-9) in cerebrospinal fluid (CSF) and serum,insu-lin-like growth factor-Ⅱ(IGF-Ⅱ) and insulin like growth factor binding protein-3(IGFBP-3) in CSF before and after treatment and the incidence of adverse reactions. There were no obvious adverse reactions during the treatment. RESULTS:After treatment, the VEGF and MMP-9 in serum and the VEGF,MMP-9,IGF-Ⅱ and IGFBP-3 in CSF in 2 groups were significantly lower than before,and observation group was lower than control group,with significant differences(P<0.05). There was no adverse reactions in 2 groups during the treatment. CONCLUSIONS:Compared with ribavirin,acyclovir can more obviously improve the neurological function and cytokines of children with viral meningitis,with similar safety.

Objective To investigate serum procalcitonin(PCT)and C-reactive protein(CRP)and clinical significance of changes in children with pneumonia.Methods 123 cases of childhood pneumonia included 48 cases of bacterial infection,mycoplasma infection in 36 cases,39 cases with viral infections,40 cases of physical healthy children were selected as the control group.They were measured in serum PCT and CRP content of the correlation between test results and analysis of clinical final diagnosis.Results The level of PCT in Bacterial pneumonia group, Mycoplasma pneumonia group and viral pneumonia group were (5.80 ±1.92)μg/L,(0.45 ±0.15 )μg/L and (0.32 ±0.17)μg/L,respectively,significantly higher than control group(0.19 ±0.10)μg/L(t =5.37,3.41,1.23, all P <0.05);the level of CRP in Bacterial pneumonia group,mycoplasma pneumonia group and viral pneumonia group were(45.34 ±13.35 )mg/L,(28.63 ±11.37)mg/L and (8.19 ±2.07)mg/L,respectively,significantly higher than control group(3.85 ±1.31)mg/L(t =5.37,3.41,1.23,all P <0.05);serum PCT sensitivity to detect pneumonia children,specificity and the positive predictive were 93.56%,82.35% and 69.25%,respectively,higher than serum CRP diagnosis of pneumonia sensitivity,specificity and positive predictive(χ2 =4.41,5.83 and 7.62, respectively,all P <0.05).Conclusion Serum PCT and CRP measurement can be used as an auxiliary to identify indicators of childhood pneumonia,the diagnosis of pneumonia in children has important clinical significance.

There are many progresses in the therapy of MM with ASCT. ASCT improves the ratio of CR,EFS and OS,compared with conventional chemotherapy.Myeloma patients with renal failure or old age also can be candidate for ASCT.Tandem autologous transplantation improves the ratio of CR. Its impact to long-term EFS and OS still need to be judged.To improve conditional project,to choose suitable time,and- toselect consolidation schedule can boost therapeutic effect.

In order to improve the production of agro-antibiotic 2-16,the producing strain(Streptomyces ahygroscopicus var.huangshanensis) was treated by protoplast regeneration,ultraviolet radiation,NTG mutagenesis and low energy C~(+) ion implantation.At last,a high-yield strain No.515 was obtained.The production of ~()No.515 was increased by 223.10%.By using Plackett-Burman design and Response Surface Analysis provided by SAS software,the cultivation condition of No.515 was optimized.The amount of agro-antibiotic 2-16 was increased by 38.53% when the strain No.515 was cultivated in the optimum medium instead of the initial one.

The intracellular hepatitis B surface antigen (HBsAg) content per cell was increased by 7.2-fold in the culture with 1.5% dimethyl sulfoxide (DMSO) compared with that in the control without DMSO, while the extracellular HBsAg production and specific productivity were only improved by 70% and 3.2-fold, respectively. Electron microscope has been employed to reveal large dilated structures within recombinant CHO cells in the presence DMSO. The dilated structures have a distribution within whole cytoplasm, and some dilated areas were engulfed in the nucleus. These large, dilated structures were not observed in the control. Immunogold labeling was used to discover the accumulated HBsAg was localized within these dilated areas, and some HBsAg-specific labels were detected in the nucleus membrane, owing to the encroachment of the dilated areas upon nucleus. The result could help to reveal the mechanism of intracellular HBsAg accumulation in the presence of DMSO.

In this study, an approach based on triple-color fluorescence probes was developed for screening potential nephro-protective bioactive substances. Three fluorescent probes (i. e. FDA, MTR and Hoechst 33342) were used to label HK-2 cells injured by doxorubicin hydrochloride, and cellular fluorescence images were subsequently acquired and analyzed by a cellular-fluorescence image microscopy platform. The established method was applied to screening 53 components of Carthami Flos, and three components C17, C18 and C19 were found to exhibit nephroprotective effects against doxorubicin hydrochloride induced injury on HK-2 cells. Eight compounds (i. e. hydroxysafflor yellow A, 6-hydroxykaempferol-3-O-rutinoside-6-O-glucoside, 6-hydroxykaempferol-3,6-di-O-gluco-side or 6-hydroxykaempferol-6, 7-di-O-glucoside, 6-hydroxykaempferol-3-O-rutinoside, 6-hydroxykaempferol-3-O-glucoside or 6-hydroxykaempferol-7-O-glucoside, rutin, isoquercetin, and kaempferol-3-O-rutinoside) in components C17, C18 and C19 were preliminarily identified by liquid chromatography-mass spectrometry (LC-MS). Isoquercetin, rutin, kaempferol-3-O-rutinoside, and hydroxysafflor yellow A were confirmed by comparing with reference substances, Further study indicated that these four compounds had moderate nephroprotective effects, while isoquercetin showed a significant nephroprotective effect in a dose-dependent manner. These results suggest that isoquercetin, rutin, kaempferol-3-O-rutinoside and hydroxysafflor yellow A might be the nephroprotective bioactive substances in Carthami Flos.

OBJECTIVETo study the clinical efficaly and safety of Tiepi Fengdou Granule (TFG) and Capsule (TFC) combined with chemotherapy and/or radiotherapy in treating lung cancer patients with Qi-Yin asthenia syndrome (QYAS).

METHODSEighty patients were randomly assigned into 3 groups: the TFG group (32 cases), the TFC group (32 cases) and the Shengmai Capsule control group (16 cases). Changes of symptoms of QYAS, main symptoms of lung cancer, Karnofsky scoring as well as the blood routine test were observed.

RESULTSThe total effective rate of symptom improving in the TFG group and the TFC group was 81.2% and 93.3% respectively, showing insignificant difference between the 2 groups (P > 0.05), but both were higher than that in the Shengmai Capsule control group (50.0%, P < 0.05 and P < 0.01). Additionally, as compared with those before treatment, the neutrophil count increased and the lymphocytes count obviously decreased in the TFC group after treatment (all P < 0.05).

CONCLUSIONBoth dose-forms of the remedies, TFC and TFG, have significant effects in treating lung cancer with QYAS, but with insignificant difference between them.
