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 explore the effect of swallowing training on dysphagia in patients with head and neck neoplasm receiving ra-diotherapy. Methods 60 patients with head and neck neoplasm receiving radiotherapy from March, 2014 to August, 2015 were divided into intervention group (n=30) and control group (n=30) randomly. The control group received routine nursing and relevant health education, while the intervention group received swallowing training from 2 weeks before to 3 months after radiotherapy. They were assessed with Functional Oral Intake Scale and M. D. Anderson Dysphagia Inventory 1 week, 3 months after radiotherapy. Results The scores of Function-al Oral Intake Scale (Z=-3.195, P<0.01), the total score of M. D. Anderson Dysphagia Inventory and the subscores (t>4.385, P<0.01) were better in the intervention group than in the control group 1 week after radiotherapy, as well as 3 months after radiotherapy (Z=-4.436, P<0.01;t>5.361, P<0.01). Conclusion Swallowing training could improve the condition of dysphagia of head and neck neoplasm patients after radiotherapy.

Purpose To investigate the diagnostic value of dual energy CT spectrum curve combined with CT morphology in central lymph node metastasis of papillary thyroid carcinoma (PTC).Materials and Methods Thirty-one PTC patients who accepted dual energy CT double-phase enhanced scan before surgery were analyzed.Central lymph nodes with short diameter ＞ 5 mm were labelled using axial plus 3D positioning.Preoperative labelled lymph nodes were collected and marked during operation.The CT morphology of metastatic lymph nodes was analyzed.The spectrum curve slope (K) difference between metastatic and non-metastatic lymph nodes of arterial-phase and venous-phase primary lesion was compared.The critical K value and the diagnostic efficacy of K value combined with morphology were obtained according to receiver operating characteristic (ROC) curve.Results A total of 73 central lymph nodes were obtained from 31 patients,among which 51 were metastatic and 22 were non-metastatic.There was no significant difference in K value between metastatic and non-metastatic lymph nodes of arterial phase group (P＞0.05).While,there was a significant difference in K value between metastatic and non-metastatic lymph nodes of venous phase group (P＜0.05).For venous phase,the sensitivity and specificity of the K value in diagnosing central lymph node metastasis were 62.7％ and 59.1％,respectively,and combined with morphology,the sensitivity and specificity reached 76.5％ and 81.8％,respectively.Conclusion The K value of CT spectrum curve is of certain significance in predicting PTC central lymph node metastasis,and the K value combined with CT morphology can improve the accuracy of diagnosis.

Objectives To understand essential basis data availability for implementation of cost accounting in TCM hospitals. Methods Costs of a total of 1588 TCM hospitals were investigated by conducting the baseline survey via questionnaires in 2013. Results Departmental basic data (including ratio of office staff and entire staff, ratio of outpatient and inpatient departments in clinical department), and construction data for housing were well accessible, while utility fee and internal service data were not. Conclusion ①Public TCM hospitals need to improve and specify the basic cost data. ②Differences exit among different types and levels of hospitals in the availability of data. ③There are still difficulties in carrying out cost accounting in public TCM hospitals, which needs strong supports from all relevant departments.

ATP binding cassette C4(ABCC4,MRP4)plays an important role in transshipment physio-logic,endogenous or exogenous substances. The over expression of ABCC4 gene has been found in many kinds of solid tumors and hematological malignancies. The target gene also influences metastasis and recurrence process. ABCC4 can reduce the intracellular concentration and the sensitivity of various chemotherapy drugs, which is bad for prognosis.

Objective To explore the influence of different relaxation training time on relaxation effect of patients with coronary heart disease. Methods 108 patients with coronary heart disease were randomly divided into the morning group, the night group and the morning-night group, each group adopted morning, night and morning-night relaxation training. The relaxation effect was compared between these groups. Results Significant difference existed in sleep quality, anxiety condition and hypnotic dose of the patients in these groups. The time factor played a significant role in the effect of relaxation. The morning group was different in sleep quality improvement and anxiety condition alleviation from the night group and the morning-night group. Conclusions Relaxation training at night or morning-night could effec-tively help improve the sleep quality of patients, decreasing the level of anxiety and tendency of hypnotic in pa-tients with coronary heart disease.

Recent studies reported that thymoquinone (TQ), a component derived from the medicinal spice Nigella sativa (also called black cumin), exhibited inhibitory effects on cell proliferation of many cancer cell lines. This study was performed to investigate the anti-metastatic effect of thymoquinone on the pancreatic cancer in vitro and in vivo. The results showed that thymoquinone suppressed the migration and invasion of Panc-1 cells in a does-dependent manner. To investigate the possible mechanisms involved in these events, Western blotting analysis was performed, and found that thymoquinone significantly down-regulates NF-kappaB and MMP-9 in Panc-1 cells. In addition, metastatic model simulating human pancreatic cancer was established by orthotropic implantation of histologically intact pancreatic tumor tissue into the pancreatic wall of nude mice. And administration of thymoquinone significantly reduced tumor metastasis compared to untreated control. Furthermore, the expression of NF-kappaB and MMP-9 in tumor tissues was also suppressed after treatment with thymoquinone. Taken together, the results indicate that thymoquinone exerts anti-metastatic activity on pancreatic cancer both in vitro and in vivo, which may be related to down-regulation of NF-kappaB and its regulated molecules such as MMP-9 protein. Consequently, these results provide important insights into thymoquinone as an antimetastatic agent for the treatment of human pancreatic cancer.

Based on ninety three acetylcholinesterase inhibitors (AChEIs) which have the same mechanism of action but are different in structural characteristics, the pharmacophore model for acetylcholinesterase inhibitor was constructed by the CATALYST system. The optimal pharmacophore model with three hydrophobic units, a ring aromatic unit and a hydrogen-bond acceptor unit were confirmed (Weight=3.29, RMS=0.53, total cost-null cost=62.75, Correl=0.93, Config=19.05). This pharmacophore model will act on the double active site of acetylcholinesterase and is able to predict the activity of known acetylcholinesterase inhibitors that are used for clinical treatment of Alzheimer's disease (AD), and can be further used to identify structurally diverse compounds that have higher activity treating with Alzheimer's disease (AD) by virtual screening.

Objective To explore the effect of double silicone balloon catheter used as nasal packing materials after functional endoscopic sinus sur?gery(FESS). Methods Totally 80 patients(47 males and 33 females,median age of 43 years)with bilateral chronic sinusitis who underwent en?doscopic surgery under general anesthesia were randomly divided into two groups,each group with 40 patients. The hemostatic sponge group used he?mostatic sponge for postoperative nasal packing and the hemostatic catheter group used double silicone balloon catheter plus medical sponge. Patients were observed for postoperative pain,ventilation and bleeding after packing removal to evaluate efficacy. Results Double silicone balloon catheter was superior to hemostatic sponge in ventilation maintenance(mean scores:78.8 vs 2.32)and pain relief(mean scores:0 vs 5.26),the difference was statistically significant(P<0.05). Moreover,double silicone balloon catheter was also superior to hemostatic sponge regarding to nasal bleeding after packing removal. Conclusion Double silicone balloon catheter is a preferable material for nasal packing after endoscopic surgery,which has reliable hemostatic effect and can better maintain the nasal ventilation,reduce pain in patients,and improve the patient's quality of life during treat?ment.
