The determination and characterization of solid drug form polymorphisms plays an important role in drug quality control, selection of the production process and clinical efficacy evaluation. Vibrational spectroscopy is a powerful method for the characterization of drug polymorphisms. In this paper we review recent research and application advances in the polymorphic characterization of active pharmaceutical ingredients (APIs) and drug cocrystals/salts by using Fourier transform infrared (FTIR) and Raman spectroscopy to elucidate the characteristics of APIs and drug complexes. This may provide theoretical support for structural analysis during the development process for drugs.

Objective To investigate the plasma visfatin levels and explore the relationship between visfatin and anthropometric parameters,glucose,lipid profile,insulin sensitivity index and insulin secretion index in the subjects with different glucose tolerances.Methods Fifty-three patients with newly diagonosed type 2 diabetes(T2DM),7 subjects with impaired glucose tolerance(IGT)and 35 healthy controls were enrolled.Visfatin levels were measured along with the BMI,blood pressure,lipids,glucose,insulin and HOMA-IR indexes.Results Plasma visfatin levels were elevated in patients with newly diagnosed T2DM compared with IGT group or controls.There was no significant difference in the visfatin levels between IGT group and healthy controls.Plasma visfatin level was positively correlated with glucose levels and HOMA-IR,and negatively correlated with insulin secretion index(HOMA-B).Multiple regression analysis showed that postprandial plasma glucose was independent related factor influencing plasma visfatin levels.In T2DM group,plasma visfatin concentration was positively correlated with HbA1c level.Conclusion The increased plasma visfatin concentration in newly diagnosed and untreated type 2 diabetes mellitus represents a compensatory mechanism aimed at ameliorating the functional consequences of insulin deficiency.

Objective To explore the significance of ultrasound in choosing the delivery modality in 200 cases scarred uterus gravida′s second deliveries .Methods The study selected 200 cases late pregnancy gravidas who had once uterine incision delivery history and analyzed clinical data retrospectively ,all of them were chosen from September 2010 to September 2013 in our hospital . All cases were taken by transabdominal ultrasound or transvaginal ultrasound firstly ,then taken by transabdomina transvaginal ul‐trasound ,finally contrast obsenved the transabdomina transvaginal ultrasound detections with their caesarean section observations , meanwhile observe how the uterus scar ranking affect the delivery consequence .Results (1)A total of 200 cases had higher uterus scars visualization ratio(100 .0% ) than ransabdominal ultrasound (92 .0% )and transvaginal ultrasound(96 .5% )(P<0 .05);con‐trasting the transabdomina transvaginal ultrasound with the caesarean section observations ,there was no significant difference(P>0 .05) .The grading diagnosis coincidence of transabdomina‐transvaginal ultrasound was 89 .74% .(2)The UD rate ,the bleeding vol‐ume during operation and the 24 hours postoperative bleeding volume of scarred uterus gravida grade Ⅱ and grade Ⅲ were signifi‐cantly higher than grade Ⅰ (P<0 .05) .Conclusion Transabdomina transvaginal ultrasound can effectively improve the diagnosis coincidence rate of uterine scar detection and can help to chose the better delivery mode according to the scars healing .

[ Objective ] To investigate the effect of Huatan Quyu Tablets in treating carotid atherosclerosis ( CA). [Methods] Color Doppler ultrasonographic technique was used to detect the mid-intima thickness (MIT) and carotid resistance (CR) in 40 cases of CA before and after treatment with Huatan Quyu Tablets . [Results] MIT and CR were both decreased after treatment (P

Monteggia fracture dislocation refers to the fracture of the ulna with associated dislocation of the radial head. This rare injury only accounts for less than 5%of all the forearm fractures. By literature review of the history of Monteggia fracture dislocation, the authors further clarify the definition, classification, injury mechanism and treatment protocol of this special type of fracture. The key to a good result of the treatment for a Monteggia fracture dislocation is timely diagnosis and management so that anatomic reduction and stable fixation of the ulna can be achieved. In addition, enough attention must be paid to the associated injuries at the level of the elbow, including fractures of the coronoid process and the radial head as well as posterolateral rotatory instability of the ulnohumeral articulation. The factors strongly affecting prognosis include comminuted fractures of the ulna combined with fractures of the radial head and coronoid process.

For all the time the book Symptomatic Figures of Lip and Tongue(Chunshe Zhenghou Tu)was described as written by Li Jun of Qing dynasty. We made studies on historical records on Li Jun and the features and contents of this book, and proved that Symptomatic Figures of Lip and Tongue was not written by him, but a Chinese medical book written by Japanese.
