The rapid progress in surgery in China has been closely related to government investment in public health care, construction of medical talents team, and basic and clinical research. The achievements of bench studies promote the development of clinical surgery. Translational medicine (bench-bedside-bench) has gained much attention in the medical community. The driving force promoting long-term development of surgery in China includes collaboration of basic scientists and surgeons, cultivation of surgeons with aptitude in scientific research, initiation of clinical research and popularization of multidisciplinary team.

Gastric cancer remains one of the most common causes of cancer-related death in China. Radical operation is the only potentially curative therapy for advanced gastric cancer (AGC). D2 radical gastrectomy has been widely accepted as a standard surgical procedure for patients with AGC in China. Several clinical trials have revealed that more extended resection than D2 surgery has no impact on survival. In order to improve the prognosis of AGC patients, it is necessary to carry out the preoperative TNM staging for selecting a reasonable therapeutical modality before surgery. Multimodality treatment involving perioperative chemotherapy, radiotherapy or molecular targeting agents in addition to surgery have been thought to be promising treatment strategy. In this article, we present an update on the current literature regarding the trends of surgical multimodal treatment for the patients with AGC.

The incidence of gastric cancer has declined worldwide in the past decades. However, due to the large number of population in mainland of China, the absolute number of newly-diagnosed patients in this developing country is still very high. Most of the major clinical centers have established multi-disciplinary team, but the strategy in treating this life-threatening disease still needs to be optimized, including the precise preoperative staging by various techniques, perioperative chemotherapy for locally advanced diseases, role of minimally invasive surgical approaches in treating patients with different stages, translational research to fill the gap between clinical trials and basic research, as well as the individualized treatment for gastric cancer. We believe that the biological behaviors and molecular events of gastric cancer in eastern countries are different from that of Western countries, so the clinical evidences derived from Eastern countries need to be strengthened to enrich the unmet demands in the clinical practice in China.

Objective:To explore the clinicopathologic features of 112 patients with mantle cell lymphoma (MCL). Methods:Da-ta from 112 MCL cases were collected, and immunohistochemical assay was conducted. A break in the CCND1 gene was detected by fluorescence in situ hybridization (FISH). The t-test was used in the statistical analysis. Results:All tumor cells in the 112 cases ex-pressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all the cases, 106 expressed CD5 and 104 expressed cyclinD1. A break in the CCND1 gene was not found in 3 cases with CD5-MCL. IgH/CCND1 polyploid was found in 2 classical cases. Conclusion:MCL is a type of special immunophenotypic B-cell lymphoma. The prognoses of blastoid and polymorphic subtypes are poor. Special subtypes should be classified during diagnosis.

BACKGROUND:Tantalum rod implant technology is a new method of early osteonecrosis treatment. Current research on stress distribution before and after tantalum rod implant in different sizes of femoral head necrosis area is few. OBJECTIVE:To analyze the stress distribution before and after tantalum rod implantation in different sizes of necrotic femoral head area using three-dimensional finite element method. METHODS:Three-dimensional finite element models of normal femoral head and necrotic femoral head of 15, 20 and 30 mm diameterwere constructed. Eight measuring points were chosen on two tiers of each necrotic model to detect the stress distribution and its alteration before and after tantalum rod implantation. RESULTS AND CONCLUSION:(1) Stress concentration werefound on every necrotic femoral head, most pronounced on the one with 30 mm lesion. (2) Tantalum implant appeared to reduce the stress concentration generaly. Comparison of the peak points of these models indicated most significant benefit in 15 mm lesion, next in 30 mm lesion, last in 20 mm lesion. (3) Results indicate that larger lesion entails more concentrated stress distribution and more likely to colapse. Tantalum rod implantation can delay the development of necrosis of the femoral head, andismost effective in smal lesion.

Objective To study the relationship between lymph node micrometastasis in early gastric cancer and clinicopathology of tumor,and explore an appropriate operative procedure.Methods A total of 1 004 lymph nodes from 50 patients with early gastric cancer(EGC)were sliced and restained with H.E and immunohistochemical technique,respectively.Immunohistochemical staining was performed by the streptavidin-biotin immunoperoxidase method with cytokeratin-specific monoclonal antibody CAM5.2.The relationship between lymph node micrometastasis and clinicopathological characteristics of primary tumors and prognosis of EGC was analysed.Results The incidence of nodal micro-involvement was significantly increased in diffuse type cancerous lesions(n=11,32.35%)as compared with intestinal type cancerous lesions(n=1,6.25%)(P

Objective To study the clinical and imaging characteristics of patients with infectious sacroiliac arthritis.Method Twenty-one patients diagnosed with infectious sacroiliac arthritis were analyzed retrospectively between 2000 and 2014.The chief complaint was pain in hip and lumbosacral area.Their clinical features,laboratory tests and pathological examination results as well as CT/MRI/PET-CT images were evaluated.Results There were nine males and thirteen females eighteen (85.7％) patients had unilateral sacroiliac joint involvement.Among these patients,three were diagnosed with brucellosis sacroiliac arthritis(BSI),eight patients with tuberculosis sacroiliac arthritis (TSI),and ten patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis (ISI).For those patients with non-brucellosis and non-tuberculosis infectious sacroiliac arthritis,white blood cell count,erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP)were dramatically increased.Twelve patients were diagnosed pathologically including 6 ISI,2 BSI and 4 TSI.Twelve patients and seventeen patients were scanned by CT and MRI respectively.Two patients undertook PET-CT examination.Antibiotic therapy showed significant therapeutic effects in all patients.Conclusion Infectious sacroiliac arthritis patients with hip or lumbosacral pain as the chief complaint can be easily misdiagnosed as spondyloarthritis.Comprehensive analysis of clinical features,imaging and laboratory findings is essential for accurate diagnosis.
