OBJECTIVETo observe the prevention and clinical efficacy of combination of Liuwei Dihuang Pill (LDP) and Ginkgo Leaf Tablet (GLT) for early diabetic retinopathy (DR).
METHODSUsing randomized, double-blind, double simulation, parallel controlled clinical trial, 140 type 2 diabetes mellitus (T2DM) outpatients were recruited and assigned to the treatment group and the control group, 70 in each group. All patients received basic Western medicine treatment (such as blood glucose and pressure control). Patients in the treatment group took LDP (8 pills each time, 3 times per day) and GLT (19.2 mg each time, 3 times per day), while those in the control group took LDP placebos and GLT placebos. All treatment lasted for 24 consecutive months. All subjects were followed-up every month. The general clinical data as sex, age, and metabolic data such as blood glucose, blood pressure, blood lipid, and DR prevalence rate were collected and statistically analyzed.
RESULTSThere was no significant difference in levels of blood glucose, blood pressure, or blood lipid between the two groups (P > 0.05). After treatment the DR incidence rate was significantly lower in the treatment group than in the control group [3.1% (2/64) vs 18.6% (11/59), P < 0.05)]. Meanwhile, the DR prevalence rate of the treatment group was also significantly lower than that of the control group [6.3% (4/64) vs 20.0% (13/59), P < 0.05].
CONCLUSIONCombination of LDP and GLT could effectively prevent and treat the development of DR in T2DM patients.

Objective To re-evaluate the prognostic value of the 6th edition of UICC/AJCC staging system in patients with nasopharyngeal carcinoma (NPC) treated with intensity-medulated radiation therapy (IMRT). Methods From February 2001 to March 2007, Clinical data of 570 NPC patients initially treated with IMRT in Cancer Center of Sun yat-sen University were reviewed and the long-term survival was analyzed according to T, N and overall stages. Results The median follow-up was 42 months. 184 patients were followed up to 5 years. The 5-year local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS) and overall survival (OS) of the whole group were 93. 0%, 85.4% and 83. 3% ,respectively. No statistically significant difference of LRFS was detected between the either two of stage T_1, T_(2a) and T_(2b)(100%, 100% and 94. 5% ;T_1 vs. T_(2b), χ~2 = 1.92, P =0. 166 ;T_(2a) vs. T_(2b), χ~2= 0. 35, P =0. 555), stage T_(2b) and T_3 (94. 5% and 91.3% ;χ~2 = 2. 62, P = 0. 106), or stage T_3 and T_4 (91.3% and 89. 5% ; χ~2 = 1.55, P =0. 214). The 5-year DMFS of stage N_2 was similar with stage N_1 or stage N_3(80. 2%, 86. 2% and 61. 4% ; N_2 vs. N_1, χ~2=2.22, P=0.136;N_2 vs. N_3, χ~2= 1.92, P=0.165). No statistically significant difference of 5-year OS was observed among stage Ⅰ , Ⅱ_a and Ⅱ_b(91.7%, 100% and 95. 3% ; Ⅰ vs. Ⅱ_b χ~2 =0.32, P=0.574;Ⅱ_a vs. Ⅱ_b,χ~2-0.25, P=0.617), or between Ⅳ. And Ⅳ_b(67.9% and 75. 0% ;χ~2 = 0.25, P = 0. 616). Conclusions The 6th edition of UICC/AJCC staging system shows poor predictive value for the long-term survival of NPC patients treated with IMRT.

AIM To study the therapeutic effect of bone marrow transplantation on mustard gas-poisoned mice. METHODS Mustard-poisoned mice model was constructed by injected mustard gas 20 mg·kg~(-1) subcutaneously. At 4 h, 1 d and 2 d after poisoned by mustard gas, the suspended bone marrow cells (106 cells per time) were injected into mice respectively. After poisoned 3, 5, 7 and 10 d, the numbers of leukocyte and marrow nucleated cells were recorded periodically. At the same time, after poisoned 4 h and 1 d by mustard gas, mice in another group were injected granulocyte colony stimulating factor (G-CSF) 74 μg·kg~(-1) combined with transplantation and changes of the cell number were observed. RESULTS Compared with poisoned group without transplantion, leukocyte number in bone marrow transplanted group presented ascending trend, but there was no statistical significance until the 10 d after poisoned. However, the number of marrow nucleated cell increased significantly from the 5th day. After mice injected bone marrow cells combined with G-CSF, leukocyte increased markedly in earlier stage compared with transplantation only. CONCLUTION The bone marrow transplantation has significant effects on improvement of marrow hematogenic system inhibited by mustard gas.

AIM: To determine differentially expressed genes associated with cell adhesion and immune regulation in peripheral blood eosinophils from asthmatic patients. METHODS: Peripheral blood eosinophils were isolated from the asthmatic patients at the time of exacerbation and after improvement. Total RNA was extracted. Super SMART PCR cDNA was synthesized, suppression subtractive hybridization (SSH) and PCR-select differential screening technology were used to detect expressed genes. The differentially expressed genes were sequenced. RESULTS: High efficiency subtractive cDNA library was constructed successfully. Differential screening identified 15 differentially expressed genes, which were Charcot-Leyden crystal protein (CLC protein; galectin-10), putative pre-mRNA splicing regulator female-lethal (2D), aquaporin 9 (AQP9), IL-8, slingshot 2L (SSH-2L), PP1 catalytic subunit, beta isoform, helicase with zinc finger domain (HELZ), ?2-microglobin (?2-MG) and a gene associated with mitochondrion. CONCLUSION: Increased expression of these genes might be associated with eosinophil migration, adhesion and immune regulation. Intervention of these pathways may provide a theoretical base for future new targeting treatment for asthma.

BACKGROUND:Xenogeneic ligament is readily available, which has ligament scaffold structure and is conducive to tissue ingrowth and creeping substitution. After processing, the xenogeneic ligament, with the presence of good growth scaffold function, can be completely eliminated antigenicity that can cause immune rejection. OBJECTIVE:To study the feasibility of biological xenogeneic ligament graft instead of alogeneic ligament graft for reconstruction of goat anterior cruciate ligament. METHODS: Twenty-four healthy adult goats were randomly divided into A, B, C groups, and then, the left knee joints of goats were removed to establish animal models of anterior cruciate ligament injury in the three groups. After the establishment of the tibia and femoral bone tunnel, groups A, B, C were respectively transplanted with biological xenogeneic ligament graft combined with bone marrow mesenchymal stem cels, biological xenogeneic ligament graft alone, and alogenic ligament. RESULTS AND CONCLUSION: After implantation, no rejection but good biocompatibility was found in the group A, in which, the transplanted ligament as a functional scaffold for anterior cruciate ligament reconstruction, and new tissues in-grew and replaced the scaffold under intraarticular environment to form the new ligament with good bone tendon healing. However, there were no differences in histology, immune response, biomechanical findings between groups A and C. Additionaly, in the group A, the host tissues were found to grow into the scaffold and establish a micro-circulation. These findings indicate that xenogeneic ligament combined with bone marrow mesenchymal stem cels can accelerate the establishment of micro-circulation and promote the growth of ligaments, especialy improve the ligament revascularization significantly, but has no influence on the biological characteristics of the ligament.

With references of historical materials and modern literature regarding acupoint characteristic, a secondary analysis on the concept, origin, related factors and research methods in present research of acupoint characteristic is performed. The acupoint characteristic should be considered as an acupoint inherent attribute that could explain physiological and pathological manifestations at the same time, including location attribute and function attribute, which is related with time and treatment method. Some re-thinking on acupoint characteristic is proposed as well as advice on further research method and direction, hoping to promote the research development of acupoint characteristic.
