Non-Hodgkin's lymphoma (NHL) is a heterogeneous disease from various resources and biological characters. Currently, about 90 ％ of NHL is relative to chromosomal abnormalities. This review emphasizes chromosomal abnormalities in non-Hodgkin's lymphoma, which can not only help understanding NHL genesis,but also is useful for diagnosis on early stage and proper treatment.

Crohn's disease (CD) is a chronic granulomatous disease with unknown causes, and its incidence shows a rising trend in China. So far there is no way for the complete cure of the disease. Conventional drug therapy has many limitations. The appearance of biological agents brings new treatment options for CD and also initiates a debate over "Step-up" versus "Top-down" strategies. Rational nutrition supplement plays an important role in the comprehensive treatment of CD. This paper reviews the efficacy of conventional drugs, new progress in drug therapy, roles and status of nutritional support, and new treatment strategies for CD.

In the treatment of parenteral nutrition(PN) of preterm infants, parenteral nutrition associated cholestasis(PNAC) is the most common complication. However, the mechanisms of how this complication happens are unknown. This paper summarizes the research reports about PNAC both at home and aboard in recent years and raises various precautions on premature birth avoiding, reasonable feeding, PN projects optimizing and so on.Ursodeoxycholicacid is the first-line drug in the current treatment for PNAC.

Circular RNA (circRNA) is widely found in various species' cells.They have several characteristics including structural stability,high expression and expression in a tissue-specific manner.Recent studies have demonstrated that circRNA is a member of competing endogenous RNA (ceRNA).CircRNA regulate the expression of related RNA molecules via binding with target microRNA (miRNA) and play an important role in gene expression and regulation.The finding of circRNAs not only expand our understanding about eucaryon and ceRNA regulation network,but also indicate that circRNA might be a new biological marker for diagnosis and has good application prospects in drug development research,and disease diagnosis and treatment.Because current research on circRNA is still very few,a brief summary about circRNA is presented in this paper for further research.

Inhalation injury seriously threatens the survival and quality of life in burn and trauma patients. So far there is no breakthrough in the treatment of inhalation injury. A significant advance has been witnessed in the experimental study of the use of stem cells in the treatment of lung injury in recent years. In this paper, according to the results of our study in the systemic transplantation of bone marrow mesenchymal stem cells for the treatment of inhalation injury, the effect of mesenchymal stem cells on anti-inflammatory process and repair of lung tissues in inhalation injury, and its possible mechanisms are reviewed.

Objective To investigate the role of IP-10 in the pathogenesis of ankylosing spondylitis (AS). Methods The peripheral blood monocytic cells (PBMC) were collected from 39 AS patients, and the mRNA expression of IP-10, IFN-? and IL-4 were measured by semi-quantitive RT-PCR with G3PDH as the internal control. Results The mRNA expression levels of IP-10, IFN-? and IL-4 as well as the rate of IFN-?/IL-4 were elevated in the PBMC of AS patients compared with the healthy controls (P

Objective To analyze surgical diagnosis and treatment effect of 25 cases with gastric stump carcinoma.Methods The clinical manifestations and therapies of 25 cases with gastric stump carcinoma in our hospital from 1992 to 2003 were analyzed retrospectively.We sum up the surgical methods and postoperative survival rate.Results The postoperative survival rates of 1,3 and 5 years in 25 cases with gastric stump carcinoma were 60.2%,34.2% and 18.6% respectively,and were 81.4%,48.2% and 36.7% respectively in cases treated with radical resection.Conclusion No specific symptoms were identified,endoscopy examination periodically is the key point to detect gastric stump carcinoma.Radical resection is the most effective surgical style for surgical treatment of gastric stump carcinoma.

Objective To evaluate effects of two different flap designs (envelope flap and triangular flap) on complica?tions after the mandibular third molar surgery. Methods A randomized, self controlled clinical trial design was selected for 52 patients treated in the outpatient surgery of Stomatological Hospital Affiliated to Tianjin Medical University. Patients were treated with envelope flap design for lower third molar removal in one side and triangular flap on the other side. VAS scores were used to evaluate postoperative pain. The postoperative swelling was evaluated by patient`subjective index. The degree of the upper and lower incisor distance was used to evaluate trismus. Data of postoperative swelling, pain and trismus were re?corded 1, 2 and 7 days after surgery. Data of postoperative wound dehiscence, bleeding situation and alveolitis were also re?corded and compared between two groups. Results There were no significant differences in postoperative pain after 1, 2 and 7 days between two flap designs (P>0.05). After 1 and 2 days there was more severe facial swelling in triangular flap group than that of envelope flap group (Z=2.005, Z=2.017, P<0.05). There was more limited mouth opening after 1 and 2 days in triangular flap group than that of envelope flap group (t=2.578, t=2.410, P<0.05), but on the seventh day there was no significant difference in the severity of facial swelling and trismus between two groups (P>0.05). There were no signifi?cant differences in postoperative pain, alveolitis, bleeding and wound dehiscence between two groups (P > 0.05). Conclu?sion The envelope flap is more conductive to the early recovery in patients after surgery, but in the long term there is no ob?vious difference between the two flap designs.

Objective To evaluate the effect of FOCUS-PDCA program(find,organize,clarify,understand,se-lect,plan,do,check,act )on the prevention and control of catheter-related blood stream infection (CRBSI)in an intensive care unit(ICU).Methods Process of central venous catheterization and nursing care were analyzed by u-sing FOCUS-PDCA program,and the causes for CRBSI were found out ;a continuous quality improvement (CQI) team was established to provide training for ICU nurses,and the process was improved and supervised,virtuous cir-cle was created.Results Incidence of CRBSI decreased from 8.29‰ before FOCUS-PDCA intervention(January-December,2010)to 3.20‰ after FOCUS-PDCA intervention(January 2011 -December 2012),the difference was significant (χ2 =14.6,P <0.001).Conclusion FOCUS-PDCA program is effective for controlling the incidence of CRBSI.

Tumor dormancy is a state that tumor cells long-term exist in human body,without obvious growth. Dormant cell is one of the origins of tumor recurrence or metastasis. The exact mechanism of tumor dor-mancy is still unclear. Combined with cellular and molecular biological techniques,tumor cell transplantation and culture in vitro can establish experimental tumor dormancy-recurrence models. These in vivo and in vitro models can be used to investigate mechanisms of tumor dormancy and to explore novel treatments.
