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.

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.

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.

Objective To explore the clinical and MR imaging features of myxoid liposarcoma.Methods Clinical and MR imaging data of 7 patients with histologically confirmed myxoid liposarcomas on extremities were retrospectively analyzed.The age of the patients ranged from 41 to 59 years with a median age of 51 years.Results Three tumors occurred in thigh,two in calf,one in foot and one in shoulder.Six tumors were situated deeply,and one was superficial.On T_1-weighted images,all 7 tumors showed predominant isointense or slightly hypointense signals relative to muscle,with 6 having lacy,linear or amorphous loci of high signal intensity.The major portion of each tumor displayed hyperintense signals compared with fat on T_2-weighted images.Following the injection of Gd-DTPA,all tumors showed inhomogenous and strong enhancement.All tumors had septa and were well defined without obvious surrounding edema and invasion of the adjacent bones.Conclusion Myxoid liposarcomas usually show predominant isointense or slightly hypointense signals relative to muscle on T_1-weighted images and hyperintense signals relative to fat on T_2-weighted images.The fat components within the tumors may be identified as linear,lacy or amorphous foci of high signal intensity on T_1-weighted images.The contrast enhancement of the mvxoid liposarcomas is usually pronounced and heterogeneous.

Objective To investigate the relationship between proteinuria components and the severity of pregnancy induced hypertension syndrome (PIH), the unconcentrated urine samples from patients with PIH were analyzed on proteinuria components by electrophoresis.Methods Proteinuria components were analyzed by sodium dodecyl sulfate-agarose gel electrophoresis (SDS-AGE) in unconcentrated urine samples from PIH patients (PIH group,n=114) and normal third trimester pregnant women (control group,n=110).Results Eleven kinds of urinary protein were detected in the PIH group and four in the control group. The results showed positive relationship between the urine protein component complexity and the severity of PIH (P

OBJECTIVETo observe clinical efficacy in treating cutaneous deficiency of traumatic shank amputation stump with full-thickness skin graft combined with vacuum sealing drainage.

METHODSFrom September 2009 to December 2012, 15 patients with cutaneous deficiency of traumatic shank amputation stump were treated with full-thickness skin graft combined with vacuum sealing drainage. Among patients, there were 11 males and 4 females with an average age of 41.5 (ranged from 25 to 62) years old. Ten cases were caused by traffic accident and 5 cases were caused by heavy object, 9 cases on left and 6 cases on right. Six patients with smashed wound were treated with debridement and amputation, combined with vacuum aspiration in-emergency; 9 patients caused by infection and necrosis were treated with debridement and amputation, combined with vacuum aspiration, and full-thickness skin graft were performed at stage II. The skin defect area of residual limbs ranged from 40 cm x 20 cm to 25 cm x 15 cm.

RESULTSAll patients were followed up from 3 months to 1 year. Full-thickness skin graft of residual limbs were survived,and obtained satisfactory walking function with prosthetic. Residual skin increased thicken, wearproof without rupture and pain.

CONCLUSIONFull-thickness skin graft combined with vacuum sealing drainage in treating cutaneous deficiency of traumatic shank amputation stump could reserve the length of residual limbs, increase survival rate of skin graft with less scar of survival skin, get good wearability and it is conducive to prosthetic wear. It is a simple and easy treatment method.

Objective To study the diarrhea causes and nursing care after kidney transplantation from donation after cardiac death(DCD).Methods The clinical data of 91 patients undergoing kidney transplantations from DCD were retrospectively analyzed from November 2011 to May 2013 in our department,to investigate the incidence of diarrhea and the causes.Results Eighty three cases contracted diarrhea in 91 recipients,with the incidence of diarrhea 91.2%.The use of immunosuppressive agents,intestinal flora,infection and bowel movement dysfunction were all related to the diarrhea.Conclusions The incidence of diarrhea is high and the causes are complex after kidney transplantation from DCD.So nurses should take the appropriate care measures to improve the quality of nursing,avoiding complications and ensuring transplant results based on a different cause of diarrhea.

Objective To retrospectively analyze the influence of intensity-modulated radiotherapy (IMRT) on tumor regression in primary nasopharyngeal carcinoma (NPC).Methods 272 patients with NPC received radical radiotherapy alone,196 by IMRT with a total treatment time of 6 weeks,and 76 by bilateral field conventional radiotherapy (CRT) with the total treatment timc of 7 weeks.Results By the end of radiotherapy,the primary tumor and neck lymph node residual rates of the IMRT group were 36.7％ and 44.2％,respectively,both significantly higher than those of the GRT group (21.1％ and 26.6％,x2 =6.15,3.99,P ＜ 0.05).Three months after the radiotherapy,residual lesions were observed at the nasopharynx or neck lymph nodes in 12 of the IMRT group,with a residual rate of 6.1％,not significantly different from that of the CRT group (9.2％,7/76).The 12 residual lesions of the IMRT group all vanished completely 4 -9 months after the radiotherapy.Conclusions There is an obvious difference in regressive mode between IMRT and CRT technique in NPC treatment.At the end of IMRT,the tumor residual rate is slightly increased.However,the delivered dose of gross tumor volume (GTV) is sufficient,and the boost dose should not be delivered indiscreetly.

BACKGROUND: Peri-implant crestal bone resorption is considered as a normal reaction according to traditional butt-joint prosthesis around two-piece implants. OBJECTIVE: To evaluate bone loss around two-piece implants restored according to the platform switching concept in the posterior area of the mandible. METHODS: Eighty-eight implants were consecutively placed in 50 patients following submerged surgical protocol. In the test group, 40 Ankylos implants were placed using platform switching technique, while 48 3i implants using traditional butt-joint in the control group. All the implants were positioned at the crestal level. Definitive prosthesis was delivered after 3 months. RESULTS AND CONCLUSION: All implants were judged to be successfully osseointegrated. The success rate was 100%. Twelve months after restoration, radiographic analysis showed an average bone reduction level of (0.31±0.39) mm in the test group that was statistically significantly different (P < 0.01) from the average reduction in the control group [(0.94±0.43) mm]. In the follow-up time, no implants were loose or lost and healthy gingival was seen. These findings show that the platform switching technique can reduce peri-implant crestal bone resorption and preserve alveolar bone level around dental implants 12 months after restoration.Oral Implantology Center, Affiliated Hospital of Medical College, Qingdao University, Qingdao 266003, Shandong Province, China
