OBJECTIVETo investigate the effect of Xianxiong decoction on the mice with acute lung injury induced by lipopolysaccharide.

METHODEighty female ICR mice were randomly divided into 8 groups: model group, Xianxiong decoction group, Daxianxiong decoction group, Xianxiong decoction group without Kansui Radix group, Xianxiong decoction group without Glycyrrhizae Radix et Rhizoma group, Glycyrrhizae Radix et Rhizoma and Kansui Radix group, normal group and control group. Animals of each group, except normal group, were undertaken intraperitoneal injection and intranasal inhalation of lipopolysaccharide (LPS) on day 1, 2, 3 to establish acute lung injury (ALI) model. 30 min after modeling, 0.2 mL corresponding drugs were administrated to each mice, dexam ethasone and normal saline were given to the mice of control group and normal group respectively. White blood cell in blood, neutrophil percentage of blood and bronchoalveolar lavage fluid (BALF) supernatant, the ratio of wet and dry lung tissue ( W/D), histopathological changes of lung tissue were estimated. Sixty ICR mice were randomly divided into normal, model, control, high, middle and low dose Xianxiong decoction groups and were modeled in the same way. ELISA was applied to detect the level of NF-kappaB, TNF-alpha and IL-6 in BALF, PCR for NF-kappaB and TNF-alpha mRNA in lung tissue, and Western blot for NF-kappaB and TNF-alpha. Half of 20 ICR mice were administrated with Xianxiong decoction of its maximum tolerant normal saline.

RESULTCompared with model group, the number of WBC in blood of Xianxiong decoction group mice decreased (P < 0.01), percentage of neutrophils in both blood and BALF decreased as well (P < 0.01, P < 0.05); it also significantly reduced the ratio of W/D (P < 0.01); and found the alveolar wall, the number of inflammatory cells infiltrating improved, compared with model group. Xianxiong decoction reduced the level of NF-kappaB, TNF-alpha and IL-6 in BALF (P < 0.01, P < 0.01, P < 0.05); its high and low dose groups only found TNF-alpha level declined. Five mice died 24 h after administration of Xianxiong decoction which indicated its toxicity when other influential factors were considered.

CONCLUSIONXianxiong decoction is effective on the ALI mice induced by LPS, but it is of toxicity at 3 g x mL(-1).

OBJECTIVETo analyze the radiological parameters of the conservatively in treating distal radius fracture and investigate whether the final re-displacement can be predicted after primary reduction.

METHODSFrom January 2013 to June 2014,212 patients with distal radial fracture conservatively were treated in our hospital, 107 patients of them were excluded because of their incomplete radiological parameters;the remaining 105 patients were available for radiological were assessed after injury, there were 56 male patients and 49 female patients in this study, the average age of the patients was 51 years old (ranged from 22 to 80 years). According to AO classification, there were 47 cases of type A2 and C1, and 58 cases of type A3, C2, C3. All patients were treated by closed reduction and below-elbow cast immobilization for 4 to 6 weeks. All patients were followed up for 3 to 6 months (means 4.5 months) by X-ray, all fractures were healed. Standard AP and lateral radiographic examination was conducted before reduction and after reduction and bony consolidation,the dorsal angulation and the radial angle were measured at each time point. The linear regression was used for the analysis to find out whether the final re-displacement can be predicted after primary reduction.

RESULTSAmong 105 patients,the significant correlations were found for the dorsal angulation between the reduction time and the end time (r = 0.82) and for the radial angulation between the reduction time and end time (r = 0.85).

CONCLUSIONThe dorsal angulation and the radial angulation after complete healing can be predicted from linear the regression functions. Due to the possibility of predicting the end result, whether the fracture should receive further conservative treatment or surgical treatment can be decided immediately.

OBJECTIVETo analyze the clinical features of patients with newly diagnosed myeloma bone disease (MBD).

METHODClinical features of MBD in two hundred and five patients with newly diagnosed multiple myeloma (MM) were analyzed retrospectively. The relationship between outcome of different grades of MBD patients and their prognosis was compared.

RESULTS(1) Among the 205 patients, one hundred and fifty (72.7%) had bone pain as the first symptom. (2) According to X-ray evaluation, there were 23 (11.3%) of grade 0, 14 (6.9%) grade 1, 23 (11.3%) of grade 2, 68 (33.3%) grade 3 and 76 (37.2%) grade 4. (3) Patients with grade2-4 MBD had significantly higher ECOG performance score, marrow plasmacytes, marrow CD138(+) CD38(+) cell percentage and serum IL-6 level than those with grade 0 - 1 did (P < 0.05). Patients with grade 4 MBD presented with hypocalcemia (P < 0.05) more often than those with grades 0 - 3 diseases did. (4) There was no significant difference in response to initial induction chemotherapy among the five groups (P = 0.642). (5) Univariate analysis demonstrated that the time to progression (TTP) in grade 2 - 4 MBD groups was significantly shorter than that in grade 0 - 1 groups (P = 0.029). (6) Multivariable COX analysis did not indicate lytic bone changes was a independent prognostic factor for OS and TTP.

CONCLUSIONThere is a rather high incidence of MBD in MM patients in China. Patients with extensive X-ray bone lesions have more severe hematologic parameters than those without bone lesions did, and severe bone lesions is an important adverse prognostic factor for TTP.

A comprehensive HPLC-DAD-MS method was developed to study the chemical components of semi-bionic extract of Coptis-Evodia herb couple. The extract was isolated on a Hypersil BDS C18 column (4.6 mm x 200 mm, 5 microm) using acetonitrile-ammonium formic buffer as mobile phase by gradient elution. Detection was performed on DAD and MS equipped with an electrospray ionization (ESI) source by full scan and product full scan on positive mode. The chromatogram of Coptis-Evodia showed seventeen main peaks, eight of which were from Evodia while the others were from Coptis. By comparison of the retention time, the on-line UV spectra and MS spectra, four peaks were identified as jatrorrhizine, hydroxevodiamine, palmatine and berberine, and three peaks were deduced as epiberberine, columbamine and coptisine. In addition, berberine and palmatine were quantitatively determined. No new component was created in the semi-bionic extract of the herb couple, yet the solubilities of berberine and palmatine decreased.

The application potential of rep-PCR in typing beer-spoilage isolates was studied. The effects of different factors, including DNA templates and primers, on the quality and reproducibility of fingerprints were investigated. The CTAB protocol was shown to be the feasible method for DNA extraction. Primers BOXA1R and (GTG)5 were used in rep-PCR, and the PCR products were sequenced to identify strains isolated from two breweries. Rep-PCR fingerprint profiles were obtained by using GelCompar II software. Cluster analysis showed that the isolates belonging to Lactobacillus brevis, L. buchneri, L. casei/paracasei, L. plantarum are divided into 2 or 3 subgroups. In addition, the two rep-PCR fingerprint profiles complemented with each other in typing these isolates. Combining the similarity coefficient cut-off (SCC) of species, 9 unknown isolates were identified rapidly by using both fingerprint databases. The results indicate that rep-PCR is a simple, reliable and promising method for rapid identification of beer-spoilager.
