To summarize Professor LIU Feng-bin's clinical experience and theoretical thoughts on chronic atrophic gastritis (CAG), the study group designed a retrospective study on his case series and expert interview. First of all, the data of CAG patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2009 and 2013, e. g. herbs, diseases, syndrome type, prescription amount and number of herbs, was collected and processed. The statistical description and binary logistic regression were used to determined the syndrome type, initial basic remedy and modification. During the statistics, a complete and sub-group analysis was performed simultaneously. After the expert interview, the syndrome type and medication were finalized. As a result, a total of 228 CAG patients aged at (50.30 ± 10.18) were collected, including 151 males (66.23%). Of them, the TCM diagnosis and syndrome type were extracted from the information of 157 patients, including 115 cases with gastric stuffiness, 23 cases with gastric pain, 19 missing cases, 2 cases with spleen-stomach weakness syndrome, 57 cases with spleen deficiency and dampness-heat syndrome, 18 cases with spleen-stomach disharmony syndrome, 23 cases with syndrome of liver depression syndrome, 21 cases with liver qi invading stomach syndrome and 26 qi and yin deficiency syndrome, respectively. All of the 228 patients used totally 104 herbs, while the subgroups with 157 patients used 94 herbs. The most frequently used 15 herbs used in each groups were analyzed to determine the initial basic remedy and modification. Subsequently, based on the information of the sub-groups with 157 patients, with the syndrome type as the dependent variable, the logistic regression analysis was made on the most frequently used 32 herbs, in order to determined the modification in herbs for different syndrome types. After experts reviewed and modified, they believed the main causes of CAG were dietary irregularities, moodiness and weak constitution; the pathogenesis of CAG was spleen deficiency with qi stagnation, heat depression and blood stasis in the stomach meridian. The above six syndrome types and 12 herbs were determined, including Pseudostellariae Radix, Poria, Atractylodismacrocephalae Rhizoma, Glycyrrhizae Radix et Rhizoma, Fritillariae Thunbergii Bulbus, Sepiae Endoconcha, Arecae Pericarpium, Aurantii Fructus, Perillae Caulis, Herba Hedyotis Diffusae, Scutellariae Barbatae Herba, Curcumae Rhizoma. This study summarized Professor LIU Feng-bin's clinical experience and theoretical thoughts of chronic atrophic gastritis based on clinical practice data and expert interview, with a rigorous design and good scientificity and practicability.

Objective To study the integration and expression of HLA-B2704 gene in HLA-B2704 transgenic mice. Methods HLA-B2704 gene was introduced into fertilized eggs of C57BL/6?Kunming and Kunming?Kunming by microinjection. The founder mice were screened by PCR for integration of HLA-B2704 transgene and were then further confirmed by southern blot. RT-PCR and flow cytometry were carried out to detect the expression of HLA-B2704 gene at mRNA and protein level. Results Ten F0 hybrid mice carried HLA-B2704 gene in 101 F0 hybrid mice, 3 of 64 (4.7%) hybrid mice from Kunming?Kunming and 7 of 37 (18.9%) hybrid mice from C57BL/6?Kunming background carried HLA-B2704 gene. Statistical analysis showed that there was significant difference in the integration rate between the two groups (P

OBJECTIVETo summarize the complications and the early clinical effect of less invasive stabilization system and the femoral condylar support plates in the treatment of AO type C distal femoral fractures.

METHODSFrom September 2007 to February 2012, 46 patients with AO type C distal femoral fractures were retrospectively studied. Of all patients 25 were treated with less invasive stabilization system including 14 males and 11 females with a mean age of (56.3±4.2) years old; according to AO classification, there were 14 cases of C1, 8 cases of C2 and 3 cases of C3 with a mean hospital stay of (15.6±1.7) days. While 21 cases were treated with femoral condylar support plates fixation including 12 males and 9 females with a mean age of (53.8±5.1) years old;there were 13 cases of C1, 6 cases of C2 and 2 cases of C3 with a mean hospital stay of (17.8±2.2) days. Comparative analysis was performed from the operation related index,postoperative complications and Evanich score of the knee joint function between the two groups at follow-up.

RESULTSAll 46 patients were followed up from 13 to 38 months with a mean time of 19.6 months after surgery. Complications included 1 case with infection,3 cases with internal fixation failure, 1 case with nonunion and 1 case with activity limitation of the affected knee. The differences in the incision length, blood loss, fracture healing time were significant between two groups (P<0.05), while there was no significant difference in the duration of operations, hospital stays and the incidence of postoperative complications between two groups (P>0.05). The statistical significance was also found in the Evanich score at last follow-up between two groups (P<0.05).

CONCLUSIONPatients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time and better functional recovery. Less invasive stabilization system had became one of the ideal internal fixations in the treatment of AO type C distal femoral fractures.

OBJECTIVETo detect serum levels of MMP-9 and VEGF in patients with bladder cancer.

METHODSSerum levels of MMP-9 and VEGF in 58 patients with bladder cancer and 45 healthy controls were measured by sandwich-ELISA.

RESULTSSerum levels of MMP-9 and VEGF (737.12 micro g/L and 1148.88 ng/L) were significantly higher in the cancer patients than those of controls (423.51 micro g/L and 846.96 ng/L, P < 0.01). The serum levels were associated with tumor stage and grade. In patients with invasive cancer, the levels were significantly higher than those of superficial cancer (P < 0.01). Patients with distant metastasis had significantly higher levels of MMP-9 and VEGF than those with localized invasion (P < 0.01). But there was no significant difference between patients with superficial cancer and controls. Patients with G(3) tumors had significantly higher levels of MMP-9 and VEGF than those of patients with G(1) and G(2) tumors (P < 0.01).

CONCLUSIONSElevated MMP-9 and VEGF levels are associated with a high stage and grade of bladder cancer and they may serve as markers of tumor progression in the future.

Objective To explore the expressions of Caveolin-1 and Ki-67 in esophageal squamous cell carcinoma tissues and discuss the clinical significances.Methods The expressions of Caveolin-1 and Ki-67 in 110 specimens of esophageal squamous cell carcinoma tissues (treatment group) and 15 specimens of normal esophageal tissues (control group) were detected by immunohistochemistry technique.The correlation between their positive expression and the elinieopathologie features were analyzed.Results The positive rates of Caveolin-1 were 47.62％ (10/21 cases),70.91％ (39/55 cases),94.11％ (32/34 cases) in low,middle,and high differentiation in treatment group,had significant difference with that in control group,which was 33.33％ (5/15 cases,P ＜ 0.05).The positive rates of Ki-67 were 52.38％ (11/21 cases),85.45％ (47/55 cases),97.06％ (33/34 cases) in low,middle,and high differentiation in treatment group,had significant difference with that in control group,which was 20.00％ (3/15 cases,P ＜0.05).Expression of Caveolin-1 was positively related with expression of Ki-67 in esophageal squamous cell carcinoma tissues(r =0.545,P ＜ 0.001).The positive expression of Caveolin-1 and Ki-67 were correlated with differentiation degree,tumor-node-metastasis (TNM) stage,lymph node metastasis,and liver metastasis(all P ＜0.05).Conclusions The expression levels of Caveolin-1 and Ki-67 are high in esophageal squamous cell carcinoma tissues,which have correlation with differentiation degree,TNM stage,lymph node metastasis,and liver metastasis.

Decoction is one of the most commonly used dosage forms of traditional Chinese medicine. The stability of chemical constituents in decoction is closely related to the clinical efficacy and safety. There were few reports about the influence of metal ions in the stability of chemical constituents in traditional Chinese medicine. However, there is no evidence that metal ions in decoction water need to be controlled. In this study, 2,3,5,4'-tetrahydroxy stilbene-2-O-β-D-glucoside (THSG), one of the main constituents in Polygoni Multiflori Radix was studied. Ordinary tap water, deionized water, and water containing different metal ions were used to investigate and compare the influence on THSG. The results showed that after storage in a dark place at the room temperature for 10 days, the degradation of THSG was 7% in deionized water, while undetectable in tap water. The content of THSG could be decreased by different kinds of metal ions, and the effect was concentration-dependent. Moreover, Fe3+ and Fe2+ showed the greatest influence at the same concentration; and our study has shown that THSG decreased more than 98% in Fe and Fe2+ solutions at 500 ppm concentration. In the same time we found out p-hydroxybenzaldehyde (molecular weight: 122.036 7) and 2,3,5-trihydroxybenzaldehyde-2-O-glycoside (molecular weight: 316.079 4) were the main degradation products of THSG in tap water and water containing Cu2+, Ca2+, Zn2+, Mg2+ and Al3+. The product of THSG dimer with a water molecule was found in water containing Fe3+ and Fe2+. The above results showed that the metal ions in water could significantly influence the stability of THSG in water, indicating that the clinical efficacy and safety of decoction would be affected if the metal ions in water were not under control. It's suggested that deionized water should be used in the preparation of decoction containing Polygoni Multiflori Radix in the clinic to avoid degradation of THSG. Meanwhile, decoction prepared by tap water should be taken by patients in a short time. Our investigation provides important information and reference about the influence of metal ions on the stability of decoctions in other traditional Chinese medicine that have unstable groups such as hydroxyls and unsaturated bonds, etc.

BACKGROUNDBladder cancer is a relatively common tumor in the urinary system, in which mitomycin C (MMC)-based chemotherapy or combination chemotherapy has been mainly used to treat patients with advanced bladder cancer. The prognosis of patients with advanced bladder cancer is still extremely poor in spite of recent therapeutic advances. To improve the prognosis, the sensitivity of tumor cells to mitomycin C by the induction of apoptosis with the abating heat shock protein 70 (HSP70) expression in human bladder cancer cell lines of BIU-87 was investigated.

METHODSHSP70 expression was abated in BIU-87 cells by HSP mRNA antisense oligomers. MTT assay and the clone-forming test were used for evaluating the sensitivity of cells to MMC. Apoptosis was assessed using both fluorescent microscopy after staining the cells with Hoechst 33258 and DNA fragment ladder agarose electrophoresis. Thirty-two male six-week-old BALB/c nude mice, at the beginning of the experiment, were used to evaluate the effect of antisense oligomers (ASO) on the tumor formation in vivo.

RESULTSHSP70 expression in BIU-87 was effectively abated by HSP70 mRNA antisense oligomers. The percentage of apoptotic cells in ASO group was greater than in sense oligomers (SO) [P < 0.05, (18.31 +/- 2.89)% vs (1.89 +/- 0.74)%], nonsense oligomers (NO) [P < 0.05, (18.31 +/- 2.89)% vs (1.78 +/- 0.92)%] and blank groups [P < 0.05, (18.31 +/- 2.89)% vs (1.87 +/- 0.84)%], while the sensitivity of tumor cells to mitomycin C was enhanced. The in vivo tumor inhibition rate of ASO plus MMC (> 50%) was more than that of ASO or MMC group alone (all P < 0.05).

CONCLUSIONSThe abating level of HSP70 expression can strengthen the sensitivity of BIU-87 to MMC. One of this effect might be related to the induction of apoptosis by abating HSP70 expression.
