Objective To evaluate the quality of life of patients with diabetes mellitus in rural areas,and to analyze the main influencing factors.Methods The EQ -5D and questionnaire were used to collect information of patients with diabetes mellitus and to evaluate their quality of life.Logistic regression,multiple liner regression analyses and other statistical methods were used to analyze the related factors of life quality among rural patients with diabetes mellitus. Results A total of 416 patients with diabetes mellitus were investigated.The mean score of EQ -5D and EQ -VAS of all cases were 0.835 ±0.197 and 61.48 ±16.47 respectively,and the rates of the participants had problems at the dimensions of mobility,self -care,usual activities,pain/discomfort and anxiety/depression were 21.15%,11.54%,17.31%, 38.46% and 47.12% respectively.Logistic regressions for the five dimensions showed that complications were the common significant factors of all five dimensions,and age was related to the dimensions of mobility,usual activities,pain/discomfort and anxiety/depression.Gender and HbA1C were influencing factors of pain/discomfort dimension.Multiple liner regression analyses showed that the number of complications was the influencing factors of the valuation of EQ -5D and the score of EQ -VAS.Conclusion The quality of life among patients with diabetes mellitus in rural areas was lower than healthy people.Anxiety/depression was the most common problem,and complications were the main factor for the decrease of quality of life among diabetic patients.

OBJECTIVETo observe the effect of magnesium sulfate, Nifedipine Tablet (NT) combined Salvia Injection (SI) on endothelin-1 (ET-1), nitric oxide (NO), thromboxane A2(TXA2), prostacyclin I2(PG2), and hemorheology of preeclampsia patients.

METHODSTotally 704 preeclampsia patients were randomly assigned to the treatment group and the control group, 352 cases in each group. All patients were treated with magnesium sulfate combined NT (on the first day: slow intravenous injection of magnesium sulfate 5 g + intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg; on the second and third day, intravenous dripping of magnesium sulfate injection 10 g + oral administration of NT 30 mg), while those in the treatment group were dripped with SI additionally at 20 mL per day for 3 consecutive days. Before and after treatment plasma levels of endothelin-1 (ET-1), nitric oxide (NO), TXA2, PGi2, and hemorheology indicators [such as high blood viscosity (HBV), low blood viscosity (LBV), plasma viscosity (PV), erythrocyte rigidity index (ERI), fibrinogen (FIB)] of two groups were detected.

RESULTSCompared with the same group before treatment, serum levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the two groups after treatment (P <0. 05), but levels of NO and PG2 increased (P <0. 05). Compared with the control group in the same period, levels of ET-1, TXA2, HBV, LBV, PV, ERI, and FIB decreased in the treatment group after treatment (P <0. 05), but levels of NO and PGI2 increased (P <0. 05).

CONCLUSIONMagnesium sulfate, NT combined SI could effectively regulate the balance of ET-1/NO and TXA2/PGI2, and improve hemorheology of preeclampsia patients.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

Objective To evaluate the efficacy,adverse events of gemcitabine vs.5-FU with radiotherapy for locally advanced pancreatic carcinomas.Methods Between January 2007 and January 2011,a total of 56 patients with locally advanced pancreatic carcinomas was included and clinical data were retrospectively analyzed.All patients received 3-DCRT radiotherapy with individual dose of 1.8 ～ 2 Gy,5 times per week,and total dose of 45 ～ 50.4 Gy for 25 ～ 28 fractions,and received concurrent chemotherapy (5-FU or gemcitabine).The patients (n =30) in gemcitabine group were treated with gemcitabine (500 rng/m2 at the 1st,8th,15th,22nd day,at 10 mg · (m2)-1 · min-1,through micro-pump) during radiotherapy; 3 weeks after radiotherapy the patients received gemcitabine infusion at a dose of 800 mg · (m2)-1 · d-1,one time per week,for 3 or 4 cycles.The patients (n =26) in 5-FU group were treated with 5-FU (500 mg/m2 at the 1 ～ 5th day per week,IV),the cycle was repeated every 2 weeks during radiotherapy; 3 weeks later the patients received 5-FU infusion at a dose of 800 mg · (m2)-1 · d-1,the 1st ～5th day per week,the cycle was repeated every 2 weeks ; with a total of 3 or 4 cycles.The efficacy and adverse events were observed,and the patients were followed until June 2013,and the median survival,1 year and 2 year survival was calculated.Results Of the 56 patients,the overall response (CR + PR) rate was 73.2％,and it was 65.3％ in radiotherapy with 5-FU group,80.0％ in radiotherapy with gemcitabine group (P ＜ 0.05).The overall one and two year survival rate was 48.2％ and 14.3％,while median survival was 15.2 months,and the corresponding values were 42.3％,11.5％,13.3 months in radiotherapy with 5-FU group,and 53.3％,16.7％,16.6 months in radiotherapy with gemcitabine group,and the survival difference between the two groups was not statistically significant (P =0.071).At the end of treatment,the pain-relief rate (VAS score ＜4) of the 56 patients was 83.3％,it was 75.0％ in 5-FU group and 90.0％ in gemcitabine group.In radiotherapy with gemcitabine group,the incidence of 3～ 4 grade myelosuppression was significantly higher than that in radiotherapy with 5-FU group,and the difference between the two groups was statistically significant (20.0％ vs 7.6％,P ＜ 0.05).Conclusions For the locally advanced pancreatic carcinomas,radiotherapy with gemcitabine can improve pain-relief and prolong survival compared with radiotherapy with 5-FU,but the incidence of adverse event of myelosuppression is higher.

A 77-year-old man was admitted to our hospital at July 5th,2010 with an unexplained massive pericardial effusion for 10 years.With dyspnea for one month and normal vital signs without pulsus paradoxus,other physical examination included a small amount of moist rale,normal heart sounds,jugular vein engorgement,positive hepatojugular reflux,hepatosplenomegaly and pitting edema of the extremities.The patient had a complex past history with lymph node tuberculosis,primary artertial hypertension,polycythernia vera,chronic renal insufficiency and hypothyroidism (Hashimoto's thyroiditis),and moreover,received a high dose radiation of 31p in 1967. Family history is negative.The patient had no cardiac tamponade or pericardial constriction during 10 years,he received pericardiocentesis twice,and pericardial effusion was exudative with a high proportion of monocyte.There was no evidences of tuberculosis infection,hypothyroidism,malignant tumor,severe heart failure,uremia,trauma,severe bacterial or fungus infection,chronic myeloid leukemia or bone marrow fibrosis during the admission. The patient refused anti tuberculosis,indwelling catheter drainage or surgical therapy.In this rare case,the aetiology of chronic massive pericardial effusion is most probably chronic idiopathic recurrent pericarditis.

The ABCD2 score is validated for evaluating short-term stroke risk after transient ischemic attack (TIA); however, whether it is able to predict the long-term risk of vascular outcome remains uncertain. Recently a new tissue-based definition of TIA has been proposed. The ABCD2 scores of 145 TIA patients admitted to our hospital were retrospectively calculated and stratified into two categories: ≤ 3 points (low risk); 4-7 points (moderate-high risk). At a median follow-up of 81 months, new vascular events were recorded. Follow-up data were available in 107 patients. Seventy one patients had a moderate-high ABCD2 score. Sixty six patients experienced a cerebral ischemic event; 8 a myocardial infarction; 7 died of cerebrovascular or cardiovascular cause. Moderate-high ABCD2 score was significantly associated with the further cerebral ischemic events (hazard ratio [HR], 1.755; 95% confidence interval [CI], 1.019 to 3.024) and with the combined endpoint (HR, 1.818; 95% CI, 1.079 to 3.063). Our study shows that the ABCD2 score may also be used to predict long-term vascular outcome after tissue-based definition of TIA. Moderate-high ABCD2 score is associated with an increased general vascular risk in the long-term follow-up after TIA.
