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.

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.

A new method for the comparison of the treatment efficacy for specific diseases or conditions between Chinese medicine and Western medicine, which serve the same medical aim but are based on substantially different theoretical systems, was identified. Abiding by the principle of parallel subgroup design of a randomized controlled trial (PSD-RCT), participants were recruited following identical inclusion and exclusion criteria and were randomly allocated into two groups to receive treatment using the respective approaches of Chinese medicine and Western medicine. The Chinese medicine group was divided into subgroups according to the theory of Chinese medicine and the Western medicine group was also divided into subgroups according to the theory of Western medicine. The treatment for each subgroup was well defined in the protocol, including major formulae and principles for individualized modifications. The primary outcome measure was ascertained to be directly related to the patients' status but independent from both theories of Chinese medicine and Western medicine, while the secondary outcomes were represented by the patient-reported outcomes and some laboratory tests commonly accepted by Chinese medicine and Western medicine. Then, taking functional dyspepsia as an example, the authors explain the framework of the PSD-RCT for efficacy comparisons between Chinese medicine and Western medicine, and recommend that the PSD-RCT can be used to compare treatment efficacy for a specific disease or condition between Chinese medicine and Western medicine, and the comparison among subgroups can provide valuable clues for further studies.

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.

OBJECTIVETo develop and evaluate the short version of patient reported outcomes (PROs) questionnaire for gastric stuffiness (Wei Pi) patients with modern test theory and technologies, hoping to provide testing tools for related clinical practice and scientific researches with higher quality and less administrative and response burdens.
METHODSUsing descriptive study design, clinical data were collected with sociological questionnaire and previous developed full items version of PROs instrument for gastric stuffiness (Wei Pi) patients via field and online surveys between Sep 2011 and Mar 2012. The statistical analysis group identified the termination parameters firstly, and then selected items with discrimination, fitting residual, item information curve (IIC) , item characteristic curve (ICC), and the rank of computerized adaptive testing (CAT) select proportion, etc. After assumption evaluation of item response theory (IRT), IIC, ICC, difficulty coefficient distribution, items-response relation and thresholds, etc. were used for psychometric evaluation of instrument.
RESULTSA total of 331 patients [Ages: 31.99 +/- 10.29 yrs; Male: 186 (56.3%)] were enrolled in statistical analysis. The test termination criterion was Max SE = 0.2 or Max items number =16. After items selection, a 15-item short version of instrument, which contains symptoms facet (8 items) and impact facet (7 items) was generated. With good unidimensionality, local independence, and monotonicity, the IC and ICC in IRT analysis showed good working capability of the questionnaire. The difficulty coefficient distribution and items-response relation were also rational, as well as response thresholds.
CONCLUSIONSThe short version of PROs instrument for adult gastric stuffiness (Wei Pi) patients was successfully developed and assessed. The instrument with good methodological and reporting quality could be used in clinical and scientific evaluating their symptoms and impact.

The prognostic value of phosphatidylinositol-4,5-bisphosphate 3-kinase,catalytic subunit alpha (PIK3CA) in patients with esophageal squamous cell carcinoma (ESCC) is controversial.We aimed to investigate the prognostic significance of PIK3CA mutation in patients with ESCC.EMBASE,PubMed,and Web of Science databases were systematically searched from inception through Oct.3,2016.The hazard ratios (HRs) and 95% confidence intervals (CI) were calculated using a random effects model for overall survival (OS) and disease-free survival (DFS).Seven studies enrolling 1505 patients were eligible for inclusion of the current meta-analysis.Results revealed that PIK3CA mutation was not significantly associated with OS (HR:0.90,95% CI:0.63-1.30,P=0.591),with a significant heterogeneity (I2=65.7%,P=0.012).Additionally,subgroup analyses were further conducted according to various variables,such as types of specimen,the sample size,technique and statistical methodology.All results suggested that no significant relationship was found between PIK3CA mutation and OS in patients with ESCC.For DFS,there was no significant association between PIK3CA mutation and DFS in patients with ESCC (HR:1.00,95% CI=0.47-2.11,P=0.993,I2=73.7%).Publication bias was not present and the results of sensitivity analysis were very stable in the current meta-analysis.Our findings suggest that PIK3CA mutation has no significant effects on OS and DFS in ESCC patients.More well-designed prospective studies with better methodology for PIK3CA assessment are required to clarify the prognostic significance of PIK3CA mutation in ESCC patients.

OBJECTIVETo investigate whether the heat shock protein (HSP) 70 antisense oligomers can enhance the sensitivity of bladder cancer cell EJ to mitomycin C.
METHODSThe HSP70 mRNA of EJ cells was blocked by the 10 micromol/L HSP70 antisense oligomers, while its effect on cell growth was evaluated by methyl thiazolyl tetrazolium (MTT) and colony forming ability test.
RESULTSThe HSP70 expressions in HSP70 antisense treated group were lower than the corresponding sense and nonsense treated groups (P < 0.01). While, the increased sensitivity of EJ to mitomycin C was found in antisense treated group, compared with the corresponding sense and nonsense treated groups (P < 0.01).
CONCLUSIONThe sensitivity of bladder cancer cell EJ to mitomycin C was enhanced by the blockage of the HSP70 expression.

OBJECTIVETo explore the clinicopathological, immunohistochemical, and molecular biologic characteristics of esophageal stromal tumors and smooth muscle tumors.
METHODSTwenty four cases of esophageal mesenchymal tumors were reclassified by a panel of antibodies such as CD117, CD34 etc. The sequence of 11 exon of c-kit gene were detected in some cases.
RESULTSThere were 3 cases of esophageal stromal tumors, 20 leiomyomas, and 1 leiomyosarcoma. The 3 esophageal stromal tumors occurred in 3 men aged 71, 56 and 60 years respectively. The tumors originated from muscularis propria with the size of 4 cm, 8 cm and 14 cm in diameter. Microscopically, the tumor cells were spindle and epithelioid shaped with slightly basophilic appearance, arranged in intersecting fascicles, diffusing and palisading patterns. Immunohistochemically, the tumors were positive for CD117 and CD34. The mutation of 11 exon of c-kit gene was detected in one case. In comparison, esophageal leiomyomas occurred in a younger population. The age ranged from 30 to 60 years (mean age 41.6 years), 12 male cases, 8 female cases. 15 cases of esophageal leiomyomas were intramural tumors with a diameter of 0.8 - 10.5 cm (mean 4.5 cm) originating from muscularis propria and 5 cases which were intraluminal polyps with a diameter of 0.2 - 1.0 cm originating from muscularis mucosae. Leiomyomas were strongly eosinophilic in appearance, diffuse positivity for alpha-SMA, MSA, and desmin, and no c-kit gene mutation. One male case of leiomyosarcoma had a diameter of 5 cm and originated from muscularis mucosae and displayed a sausage-shaped polyp.
CONCLUSIONSLeiomyoma is still the most common mesenchymal tumor of the esophagus, the stromal tumor can be similar to gastrointestinal stromal tumors. Typical esophageal leiomyosarcoma is very rare and has different clinicopathologic and molecular biologic features.
