BACKGROUND:Titanium aloy and stainless steel are two common internal fixation materials, but there are some difference in their therapeutic effects and biocompatibility. OBJECTIVE:To explore the therapeutic effects and biocompatibility of titanium aloy and stainless steel internal fixation materials for the treatment of spinal tuberculosis. METHODS:Seventy-one spinal tuberculosis patients, 35 males and 36 females, aged 17-81 were enroled. Among them, 35 patients received titanium aloy internal fixation, and the 36 patients underwent stainless steel internal fixation. At the end of 12-month folow-up, Cobb angle changes, therapeutic effect and Frankel grade were analyzed in the two groups. RESULTS AND CONCLUSION:Before treatment, there was no difference in the spinal kyphosis angle and Frankel grade between the two groups. At the last folow-up, the Frankel grade and Cobb angle were both improved in the two groups (P < 0.05), but there was stil no difference between the two groups. The cure rate was 97% (n=34) in the titanium aloy group and 92% in the stainless steel group (n=33), and no significant difference was found between the two groups. These two kinds of internal fixation materials exhibited good biocompatibility, and no infection and other adverse reactions occurred. These findings indicate that both titanium aloy and stainless steel as internal fixation materials have good biocompatibility and therapeutic effects.

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 explore the current application and features of Aconite prescriptions with incompatible herbs in grade A class three hospitals in east China and central China through a clinical study and comparative analysis.
METHODClinical prescriptions containing Aconite with incompatible herbs were collected. Association rules were utilized to analyze the compatible features of these herbs.
RESULTThis analysis found that the frequently used incompatible herba; pairs are Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, with the support rate of 44.45%, occupying nearly half of the surveyed prescriptions; Pinelliae Rhizoma is the most frequently used herb in the two areas, with support rate up to 76.24%. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata and Pinelliae Rhizoma, the top 10 herbs in Central China were mostly for warming the middle jiao and tonifying qi, such as Zingiberis Rhizoma, Atractylodis Macrocephalae Rhizoma and Codonopsis Radix; Whereas those in east China were mostly for activating and nourishing blood, such as Angelicae Sinensis Radix, Chuanxiong Rhizoma, and Salviae Miltiorrhizae Radix et Rhizoma. Among the top 10 herbal pairs in the support rate, except for Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, the core herbal pairs applied in central China were mainly for resolving phlegm and warming the middle jiao, such as Pinelliae Rhizoma-Glycyrrhizae Radix et Rhizoma, Pinelliae Rhizoma-Zingiberis Rhizoma; Whereas those in east China were principally for activating blood and tonifying qi, like Atractylodis Macrocephalae Rhizoma and Pinelliae Rhizoma, Angelicae Sinensis Radix and Pinelliae Rhizoma. Among the core herbal groups in the two areas, the most frequently used herbal groups in the two areas are Aconiti Lateralis Radix Praeparata, Glycyrrhizae Radix et Rhizoma and Pinelliae Rhizoma with the support rate of 59.73%, accounting for the highest proportion among all of herbal groups.
CONCLUSIONThere are the combined clinical application of Aconite with incompatible herbs, mostly with Aconiti Lateralis Radix Praeparata-Pinelliae Rhizoma, but with differences in the combined application in east China and central China.

Objective To investigate the expression of E-cadherin and matrix metallopeptidase 7(MMP-7)and their significance in basal-like and Her-2 over-expressing breast carcinoma. Methods The protein expression of E-cadherin and MMP-7 were analyzed by immunohistochemical method in 20 cases of basal-like breast carcinoma and 21 cases of Her-2 over-expressing breast carcinoma.Statistical method was used to analyze the clinicopathological performance.Patients were followed up from 6 to 60 months.Results The ratio of basal-like breast carcinoma and invasive ductal carcinoma was 3.4%(20/501).the mean age was 49 years.The mean size of basal-like breast carcinoma(2.1 cm)was smaller than that of Her2 over-expressing breast carcinoma(3.0 cm)(P<0.05).The 5-year survival rate of patients with basal-like breast carcinoma was obviously(40.0%) lower than that of Her-2 over-expressing breast carcinoma (71.4%)(P<0.05),though,the 3-year survival rate was similar between the two groups.The protein expression of E-cadherin was down-regulated and even deficient in basal-like breast carcinoma(P<0.05).The protein expression of MMP-7 was higher in basal-1ike breast carcinoma than that in Her-2 overexpressing breast carcinoma(P<0.05).Conclusion Down-regulated expression of E-cadherin and upregulated expression of MMP-7 may be one of the mechanisms leading to high metastasis of basal-like breast carcinoma.
