Indolent B-cell lymphomas constitute a slow growing cancer of the lymphatic system. These lymphomas mainly include fol-licular lymphoma, chronic lymphocytic leukemia/small lymphocytic lymphoma, Waldenstom macroglobulinemia, marginal zone lym-phoma, and low malignant mantle cell lymphoma. These lymphomas are sensitive to chemotherapy and/or immunochemotherapy, but they cannot be cured. Furthermore, patient age at diagnosis, patient age at time of first onset or subsequent relapses, and compli-cations often influence the chemotherapy curative effect. At present, recent progress has been achieved in our understanding of dys-regulated pathways and immunologic anti-tumor responses in indolent lymphoma. In particular, the breakthrough of non-cytotoxic drugs renderschemo-freetreatment a near-future reality. In this review, we highlight these promising approaches, such as the com-bination of anti-CD20 antibodies with immunomodulatory drugs, mAbs directed against other surface antigens, and programmed cell death 1 (PD-1) receptor inhibitor or B-cell receptor signaling pathway inhibitors. Future phase III studies will evaluate the efficacy of these drugs in the context of non-chemotherapy and further clarify treatment status.

ObjectiveTo investigate the effect of puerarin on the expression of pigment epithelium-derived factor (PEDF) in the retina of diabetic rats.MethodsThe diabetic retinopathy rat model was established.Rats were randomly divided into three groups (normal,diabetic,and diabetic with puerarin injection).The pathological changes of the retinopathy were examined.PEDF was analyzed with PCR in different time point.Results Body weight of diabetic group [ ( 216.9 ± 8.37 ) g,and(179.1 ±7.56)g] was compared with normal group[ (298.2 -±6.78)g,and(323.5 -±6.45)g] in the 3 month and 5 month ( q =12.39,P ＜0.01 ; q =15.47,P ＜0.01 ).Blood glucose of diabetic group and diabetic with puerarin injection group was compared with normal group at each time point ( P ＜ 0.01,P ＜ 0.05 ).HE staining of the retina of diabetic rats indicated a diabetic retinopathy occurred in the early - stage in diabetic group,but changed slightly in the diabetic model with an injection of puerarin.The PEDF expression at the 5 month time point in normal group,diabetic group,and diabetic group with puerarin injection was 8.833 (1.200),1.650(3.300),and 8.350( 1.100),respectively.Compared with normal group and diabetic group with puerarin injection,the level of PEDF was significantly decreased in diabetic group (x2 =48.57,P ＜ 0.01 ;x2=48.46,P ＜ 0.01 ).ConclusionsPuerarin can alleviate the retinal pathological damage of diabetic rats,early intervention with puerarin can prevent from the expression of PEDF and delay the diabetic retinopathy process.

Objective The aim of this article is to discuss the relation between serum uric acid and prehypertension, and to evaluate the influence of age, obesity, fasting plasma glucose (FPG) and lipids in Chinese adults. Methods All the 14 451 non-hypertensive samples were analyzed for blood pressure, body mass index (BMI), FPG, lipids and serum uric acid. Results The serum uric acid levels were stratified by quintiles, after adjustment for relevant factors, OR values of prehypertcnsion increased with the elevated uric acid levels. Serum uric acid level was 200-380 μmol/L, it had a linear relationship with the risk of prehypertension, 200 μmol/L as a turning point for this linear relationship, FPG could affect their correlation (P ＜ 0.0001 ). Conclusions Serum uric acid was associated with prehypertension, independent of metabolic risk factors. The associations were not significant in old individuals. FPG may modify the associations.

OBJECTIVE:To provide reference for solving the shortage of national essential medicines in Changchun. METH-ODS:According to preliminary work,a questionnaire was conducted to investigate and statistically analyze the shortage situation of essential medicines in 22 higher than secondary and 50 basic medical and health institutions in Changchun;ABC analysis was used to analyze the national essential medicines in shortage;the bid results and shortage causes of the primary and secondary nation-al essential medicines in shortage were inquired. RESULTS:Totally 72 questionnaire were send out,and 72 were recycled with ef-fective recovery of 100%. The investigation results showed there were 19 shortage breeds(22 dosage forms),which lost the bid-ding,and 99 breeds(111 dosage forms)of national essential medicines in shortage,which won the bidding,including 85 kinds of chemical medicines and biological products,14 kinds of Chinese patent medicine in Changchun. Cardiovascular system drugs shows the largest number in the bid chemical medicines and biological products,and the Chinese patent medicine were mainly Fu-zheng agent and Quyu agent(internal medicine). Results of ABC analysis showed,among the 111 bid shortage dosage forms,17 were primary and 23 were secondary. The main causes for them were price raising in raw materials,lack of production,no produc-ing in manufacturers and purchase price higher than winning bids. CONCLUSIONS:Low accessibility of raw material drugs,low enthusiasm to production,lower drug price than a reasonable level,and small clinical requirements can lead to the shortage of na-tional essential medicines. It is suggested to intensify in supervising the raw materials’marketing,raising the enthusiasm of manu-facturers,perfecting the system of drug bidding,developing fixed-point production and building drug reserve system to guarantee the production and supply of national essential medicines,and satisfy clinical demands.

The interactions between genetic variations and dietary factors in type 2 diabetes mellitus have attracted some attention. Several studies revealed that dietary carbohydrate quality and quantity and increased dietary fat intake might interact with genetic variations of type 2 diabetes mellitus and increase risk of this disease. Genome-wide association studies suggest that genetic variance may modulate the association between dietary pattern and type 2 diabetes mellitus.

Objective To investigate the relationships between vascular factors and plaque morphology in the patients with acute coronary syndrome(ACS). Methods lntravascular ultrasound(IVUS) was performed on 56 consecutively enrolled patients with ACS. Cytometric bead array for seven vascular factors(sPE,t-PA, MCP-I, IL-8,IL-6,sVCAM-1, and sCD40L) was measured by cytometry. The others biomarkers were tested by ELISA or biochemistry. Differences in bio-factors were compared between vulnerable plaque and non- vulnerable plaque groups, accte myocardial infarction (AMI) and ustable angina (UA) patients, and occurring plaque rupture. The relationship between the parameters of morphology and vascular factors was analyzed. Results There were positive correlations between sVCAM-1sPE, sVCAM-1-sCD40L, sCD40L-sPE, IL-6-IL8,IL8-MCP4, and MCPI-sVCAM-1; CRP (18.868±4.907mg/L vs 5.806±3.553 mg/L)and IL-6 (19.5 pg/ml [9.2±44.6 pg/ml]vs 5.3 pg/ml [2.3～ 13.4 pg/ml])were elevated in the vulnerable plaque group(P <0.05). sCD40L(473.82±126.11 vs 237.94±34.78 pg/mi),sPE (107.214±39.90 vs 49.06±5.61 μg/L) and MCP-1(132.42±17.85 vs 127.174±13.27 pg/ml) were increased in the plaque rupture group(P < 0.05);There was correlation between tPA and plaque morphology(P < 0.05). Increases in sCD40L, MCP-1, sPE, and TC were independent factors for plaque rupture. Conclusions IL-6 and CRP may be biomarkers for vulnerable plaque and for diagnosis ofAMI, sCD40L, MCP-1 and sPE are potential markers when for plaque rupture patient present with severe ACS.

The over-activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mechanistic target of rapamcyin (mTOR) pathway is closely related to the occurrence, development and clinical prognosis of malignant tumors. Taking this signal pathway as a target can effectively inhibit tumor progression. At present, the Food and Drug Administration of the United States has approved three drugs (CAL-101, BAY80-6946, IPI-145) for the treatment of recurrent and refractory indolent non-Hodgkin lymphoma, which demonstrates significant efficacy and a manageable safety profile.

The understanding of anatomical structures and their adjacent relationship is the founda-tion and key to the development of surgical skills and clinical thinking. In clinical teaching for residents and graduate students , we took the advantage of donor operations in organ transplantation and showed abdominal anal operations anatomical features and relationships through different view angles and compre-hensive ways. This new teaching approach was designed in accordance with processes of organ donation, procurement and back-table operation. The main contents included anatomy of abdominal wall layers, rela-tionships among abdominal organs, locations and courses of important structure, as well as medical human-istic education. In the context of organ donation becoming more and more popular and standardized after the cardiac death of Chinese citizens, this teaching approach is worth exploring.
