To propose a formula method of medicated diet based on medicinal property combination patterns in this paper under the context of lack of innovation in medicated diets. By analyzing the property combination patterns of traditional Chinese medicine and commonly used foods recorded in the pharmacopoeia, medicated diet formulae were optimized by using the greedy algorithm, with the property combination patterns of classical formulae based on the syndrome differentiation and treatment. In this paper, the Baihu Rensheng decoction, which is a classical formula for treating lung and stomach heat-derived diabetes, was taken for example in the formula design. As a result, totally 18 medicated diet formulae were developed and proved to be rational in the analysis on traditional Chinese medicines and nutriology. This method expands the way of thinking for personalized diet therapies and provides theoretical basis the industrial development and clinical application of medicated diets.

The prescription combinations of traditional Chinese medicine (TCM) focuses on the taste and channel tropism, the Qi movement, as well as the compatibility according to multiple combination principles and medicinal property and flavor combination of several traditional Chinese medicines. With the in-depth study on the prescription compatibility, researchers have realized that the medicinal property theory is the core of TCM combinations. However, there is no definite method for combinations based on medicinal properties. In this paper, the authors put forward an method for designing prescription combinations based on bipartite graph and the greedy algorithm. With the medicinal property combinations of Siweilurong Pills for example, the authors proved this method could provide ideas for quickly choosing herbal medicines for prescription combinations, and discussed the prospect of this method in substituting previous and endangered herbal medicines and banned medicinal materials.

Traditional Chinese medicine (TCM) has definitely clinical effect in treating hyperlipidemia, but the action mechanism still need to be explored. Based on consulting Chinese Pharmacopoeia (2010), all the lipid-lowering Chinese patent medicines were analyzed by associated rules data mining method to explore high frequency herb pairs. The top three couplet medicines with high support degree were Puerariae Lobatae Radix-Crataegi Fructus, Salviae Miltiorrhizae Radix et Rhizoma-Crataegi Fructus, and Polygoni Multiflori Radix-Crataegi Fructus. The 20 main ingredients were selected from the herb pairs and docked with 3 key hyperlipidemia targets, namely 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase), peroxisome proliferator activated receptor-α (PPAR-α ) and niemann-pick C1 like 1 (NPC1L1) to further discuss the molecular mechanism of the high frequency herb pairs, by using the docking program, LibDock. To construct evaluation rules for the ingredients of herb pairs, the root-mean-square deviation (RMSD) value between computed and initial complexes was first calculated to validate the fitness of LibDock models. Then, the key residues were also confirmed by analyzing the interactions of those 3 proteins and corresponding marketed drugs. The docking results showed that hyperin, puerarin, salvianolic acid A and polydatin can interact with two targets, and the other five compounds may be potent for at least one of the three targets. In this study, the multi-target effect of high frequency herb pairs for lipid-lowering was discussed on the molecular level, which can help further researching new multi-target anti-hyperlipidemia drug.

Objective To investigate relationships between signal/cutoff (S/CO) ratios of antiHCV recombinant immunoblot assay (RIBA) and their positivity with different chemiluminescence immunoassay(CLIA) reagents.Methods A case-control study was performed.From March 2014 to March 2015,anti-HCV antibody was detected in 2 616 serum of outpatients and inpatients coming from Department of Clinical Laboratory,Qilu Hospital of Shandong University by three kinds of homemade CLIA reagents and one imported CLIA reagents.The positive samples were further tested by RIBA.The correlation between the positivity and the S/CO ratios was analyzed.The difference between different reagents were compared by x2 method.Results The predicted positivities of Shandong Laibo were 97.8％ and 33.3％ with S/CO ratio ≥ 26.8 and 1 to 26.8,respectively;The predicted positivities of Beijing Yuande were 96.7％ and 20％ with S/CO ratio ≥ 16.6 and 1 to 16.6,respectively;The predicted positivities of Beijing Kemei were 97.0％ and 9.8％ with S/CO ratio ≥ 16.7 and 1 to16.7,respectively;The predicted positivities of Abbott were 96.9％ and 12.8％ with S/CO ratio≥5 and 1 to 5,respectively.Conclusions Anti-HCV CLIA S/CO ratio and RIBA confirmatory test results have some relevance.Domestic reagents also can refer to import reagents determine the relationship between the positivity and the S/CO ratio.Different domestic reagent of positivity has different S/CO ratio.Although each reagent S/CO ratio to the same positivity has large difference,suggesting each manufacturer should set their products corresponding values according to the situation,providing reference for the clinical use of unit in result determination of the clinical trials.

Objective To evaluate the application value of hyperinsulinemic euglycemic clamp in the diagnosis and treatment of newly-onset diabetic patients. Methods Totally 11 newly-onset diabetic inpatients (10 patients with type 2 diabetes mellitus and 1 patient with latent autoimmune diabetes of adulthood) who were diagnosed in the Department of Endocrinology of Peking Union Medical College Hospital from January 2009 to August 2009 were included in this study. Hyperinsulinemic euglycemic clamp was applied to measure the glucose disposal rate (M value). Afterwards insulin pump therapy was applied and the total insulin dosage per day to get to the target of the fasting and postprandial blood glucose was calculated. Final]y the relationships between insulin dosage per day and the M value, body mass index (BMI) , fasting blood glucose, fasting insulin level were separately analyzed. Results The insulin dosage was only negatively correlated with M value (r = - 0. 83, P = 0. 003), and was not significantly correlated with BMI (r = 0.54, P = 0.106), fasting blood glucose (r = - 0. 16, P =0. 657) , and fasting insulin (r = 0. 16, P = 0. 659). The formula of insulin dosage and M value according to the mathematic model as follows: insulin dosage per day = - 3. 327 M + 49. 849. Conclusion Hyperinsulinemic euglycemic clamp can effectively evaluate the insulin sensitivity in the newly-onset type 2 diabetic patients, and thus can be a useful tool in deciding the clinical insulin dosage.

Objective To establish a chemiluminecentdetection method ( CLIA ) of HCV IgG antibody for the detection of HCV infection and therefore lay a foundation for the research and development of testing kit.Methods Based upon the indirect ELISA method, the microwell plate was coated with HCV-NS3 and HCV-Core antigen expressed through gene engineering, and the anti-human IgG antibody was labeled with horse radish peroxidase.In this way, the chemiluminesent detection method of HCV IgG antibody was established.Meanwhile, the serum specimen of randomly selected 198 patients infected with HCV from No.302 Hospital of PLA and 222 blood donors, and the results were compared.Results The HCV-IgG antibody, a positive consistent rate of 99.0%( 196/198 ) , a negative consistent rate of 98.2%(218/222), and a total consistent rate of 98.6%(414/420) were found through testing 420 serum specimen with self-made agent and contrast agent.One HCV positive serum was repetitively tested with the self-made agent for 10 times, and a coefficient of variation ( CV) of less than 10% was found.Conclusion The chemiluminescent detection method of HCV IgG antibody is initially established, and the method, with an outstanding specificity and sensitivity, is applicable for screening blood donors, clinically detecting HCV infection as well as epidemiological survey.

Objective To study the clinical characteristics of primary hypoparathyroidism in adults.Methods The clinical data of 200 cases with adult-onset primary hypoparathyroidism in Peking Union Medical College Hospital during December 1987 to December 2015 were collected and analyzed retrospectively.Among them, 128 cases were followed up for a median period of 3 years.Results The major manifestations at their first visits were tetany and numbness in the distal extremities (81.5%,163/200 and 62.0%, 124/200).Thirty-two percent of the cases (62 cases) had history of seizures, and 60.9%( 98/161 ) and 74.4% ( 96/129 ) of them were with intracerebral calcifications and cataracts , respectively.Most of subjects(155/200)had more than one year delay in diagnosis.Hypercalciuria occurred in 67.2%( 86/128 ) of the cases during the follow-up.No significant differences in the clinical characteristics and biochemical markers between the hypercalciuria subjects and the non -hypercalciuria subjects.Renal nephrocalcinosis or stones were found in 6.5%( 5/77 ) of the cases , and kidney function decreased in 6.6%(6/91) of the patients.Kidney function was negatively associated with age and duration of disease.Conclusions The predominant manifestations of primary hypoparathyroidism in adults included tetany and numbness in the distal extremities and seizures .It is often misdiagnosed.Calcium supplement combined with vitamin D or its metabolites effectively relieve clinical symptoms and signs.The serum and urinary calcium levels should be monitored frequently to reduce renal complications .

OBJECTIVETo Explore the significance of preoperative screening of deep vein thrombosis (DVT) on the prevention from pulmonary embolism (PE) with color Doppler flow imaging (CDFI) in patients of lower limb fractures.

METHODSA total of 2 000 patients with lower limb fractures were retrospectively analyzed from January to September in 2010. All the patients were scheduled to be operated. There were 1 140 males and 860 females, ranging in age from 18 to 94 years, with a mean of (54.78 +/- 21.45) years. Swollen limbs could be observed in all patients when admitted and traditional Chinese medicine therapies were given by both internal and external administrations. Selective internal or external fixations were scheduled 3 to 14 days after injured and the swell relieved. CDFI screenings for DVT were applied to all the patients one day before operations and clinical data, such as gender, age, fracture site and course of diseases, were analyzed.

RESULTSOf all the 2 000 patients, 128 patients had lower limbs DVTs (6.4%). Among all the DVT patients, 52 patients had DVT within vena iliacas or femoral veins,20 patients had DVT within popliteal veins or vena crualis, 56 patients had DVT within small muscular veins of legs. Thrombolytic therapies or inferior vena cava filters were taken to 72 patients with DVTs proximal to vena cruralises and thrombi disappeared in 20 cases. Inferior vena cava filters were placed in 17 patients. There were 28 patients with either failed thrombolytic or no filters placement. All above 65 patients were treated with fracture reduction, and other 7 patients were treated with conservative methods. Of all the operated patients, one patient had PE during operation and recovered after immediately rescue. Among 56 patients with DVT within small muscular veins of legs, 51 patients were treated with reduction without other special treatment, and other 5 patients were treated with conservative methods. There was no relationship between DVT occurrence and gender. The youngest sufferer was 22 years old. DVT occurrences of patients over 41 years old were significantly higher than that of patients under 40 years old. Higher occurrences were also observed in patients with multiple fractures, fracture of femurs compared with those with tibia or fibula fractures. DVT was found as early as 3 days after injury in one case. The longer the time from injuries to operations, the higher the occurrences of DVTs.

CONCLUSIONRoutine CDFI screenings should be applied to traumatic fractured patients before operations no matter whether there are DVTs existing or not. That is very important for the prevention of fatal PE during both anesthesias and operations.
