Objective To observe the clinical efficacy of bamboo-circled salt-partitioned moxibustion in treating arthritis of temporomandibular joint.Method Eighty patients were randomized into two groups. Forty cases in the bamboo-circled salt-partitioned moxibustion group received bamboo-circled salt-partitioned moxibustion at temporomandibular joint; forty cases in the warm needling group were intervened by selecting Xiaguan (ST7), Ashi point, etc. at the affected side. For the two groups, 3-day treatment was taken as a treatment course, and the therapeutic efficacy was analyzed after 2 treatment courses. The improvements in pain and mouth opening were observed before and after the treatment, and the treatment efficacy was evaluated by a 1-month follow-up study.Result The bamboo-circled salt-partitioned moxibustion group was superior to the warm needling group in comparing the real-time analgesic effect (P<0.05) and in the improvement of mouth opening (P<0.05); the comprehensive markedly effective rate was respectively 67.5% and 45.0% in the bamboo-circled salt-partitioned moxibustion group and warm needling group, and the between-group difference was statistically significant (P<0.05), indicating that bamboo-circled salt-partitioned moxibustion is better than warm needling in treating arthritis of temporomandibular joint; the follow-up study revealed satisfactory therapeutic efficacies in both groups: the effective rate was 92.5% in the bamboo-circled salt-partitioned moxibustion group versus 87.5% in the warm needling group, and the difference was statistically insignificant (P>0.05).Conclusion Bamboo-circled salt-partitioned moxibustion can produce a real-time analgesic effect and improve mouth opening; it's especially suitable to treat the patients who are afraid of needling, as it's significantly effective, safe, non-invasive,and easy-to-operate.

OBJECTIVE: Small diameter vascular grafts (＜ 6 mm) are used predominantly in revascularization and reconstructive procedures. The small diameter vascular grafts already used in our clinical practice include autologous veins or arteries, polyethylene terephthalate (Dacron) and expanded polytetrafluoroethylene (ePTFE) synthetic vascular grafts. Unfortunately these vascular grafts all have some disadvantages that prohibit their uses. Therefore search for ideal small diameter vascular grafts has become the focus in recent years.DATA SOURCES: A computer-based online search of Pubmed database was undertaken to identify the articles about small diameter vascular grafts published in English between January 1990 and January 2007 with the key words of "prosthetic graft, vascular bypass graft, small diameter vascular graft, tissue engineering".STUDY SELECTION: The data were selected firstly to choose the full-text of articles met the criteria. Inclusion criteria: ① Articles about biological vascular grafts; ②Articles about synthetic vascular grafts; ③Articles about small diameter tissue engineering blood vessels. Exclusion criteria: Repetitive or analogical articles or case reports.DATA EXTRACTION: Totally 113 articles on small diameter vascular grafts were collected and 41 met the inclusive criteria after eliminated the repetitive or similar studies or case reports.DATA SYNTHESIS : Although biological vascular grafts have the outstanding advantages, such as superior long-term patency, relatively resistant to infection, minimal thromboembolism, etc., they also have predominant disadvantages of limited availability, durability and aneurysm formation. Dacron and ePTFE are currently the standard synthetic vascular grafts in the vascular bypass surgery, but their immediate or long-term patency rates are relatively poor due to compliance mismatch, thrombogenicity and poor haemodynamics, especially when they are used in small diameter revascularization and reconstructive procedures. Thus, various modifications have been applied to Dacron and ePTFE grafts to improve their function. In recent two decades, the emergence of tissue-engineering technology has made the development of a novel biologically viable vascular substitute feasible, and it may prove to be the ultimate solution for better small-diameter vascular grafting.CONCLUCTION: So far there is no completely biodegradable small diameter vascular graft suitable for the arterial circulation in humans. Construction of an ideal small-diameter vascular graft will require an interdisciplinary effort requiring critical contributions from biologists, engineers, and clinicians, with strong collaborations among these 3 fields being crucial to success.

Melamine is a kind of triazine compound and the fluorescence of it can get enhanced in the presence of cationic surfactant in weak alkaline medium. A new fluorescent spectrophotometry based on this principle) has been developed to determine melamine under the optimum conditions such as Tris-HCl buffer solution), pH 8.0 and with CTMAB as sensitizing agent. The linear range, detection limit and relative standard deviation were 25-1000 μg/L, 19 μg/L and 1.6%,respectively. The samples were pretreated according to the solid phase extraction monolithic column to carry out the detection of real milk. This method is simple, rapid and accurate. It can be used to screen and detect the milk samples primarily.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.

Objective To provide an anatomical basis for treatment of coronoid process fractures through an anteromedial elbow approach and evaluate its clinical effects.Methods Forty cadaveric specimens of adult upper limb were dissected to evaluate the anatomical relationships between the median nerve branches and the nearby muscles in the field of the anteromedial elbow approach.On the basis of the anatomical study,10 patients with coronoid fracture were treated from June 2014 to June 2015.They were 7 males and 3 females,from 17 to 63 years of age (average,43 years).By the O'Driscoll classification,there were 2 cases of type Ⅰ1,3 ones of type Ⅰ2,one of type Ⅱ1,3 ones of type Ⅱ2 and one of type Ⅲ2.The anteromedial elbow approach through the intramuscular space between the pronator teres and the flexor carpi radialis was used to reduce and fixate the fractures of unlar coronoid process and to explore and repair the medial collateral ligaments in all the patients.The ranges of extension,flexion and rotation of the elbow joint were measured at the last follow-ups;the function of the elbow was evaluated according to Mayo elbow performance scores (MEPS).Results The main branch of the median nerve ran between the lateral and the medial epicondyles of the humerus,27.34 mm away to the medial epicondyle of the humerus.The mean distance between the first pronator teres nerve branch and the coronoid process was 13.19 mm.The mean distance between the flexor carpi radialis nerve branch and the coronoid process was 47.02 mm.The mean distance from the medial epicondyle to the flexor carpi radialis nerve branch was 64.40 mm.All the patientswere followed up for an average of 12 months (from 6 to 18 months).Fractures united after an average of 1.8 months (from 1.5 to 2.0 months).Deformity,instability,pain or limited motion of the elbow joint was not observed during the follow-ups.At the last follow-ups,the mean flexion-extension arc of the elbow was 133.0° (from 120° to 140°),the mean rotation was 144.5° (from 130° to 160°),and the mean MEPS was 98 points (from 95 to 100 points).Conclusions The anteromedial approach through the intramuscular space between the pronator teres and the flexor carpi radiafis is a reliable and safe access for coronoid process fractures,because it leads to less injury to the median nerve than the anterior approach,and exposes the coronoid more favorably than the medial approach to facilitate reduction and fixation of the fracture fragments.

In this study, metabolism of nobiletin in rats was studied using ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS). As a result, seven major metabolites were found in bile, urine and serum of rats. Three phase I products were assigned to be demethyl and di-demethyl products, and other four phase II products were assigned to be glucuronic and sulfonic conjugates. The four phase II metabolites were reported for the first time. Among the metabolites found in the present study, the glucuronic conjugates of demethyl-nobiletin played a predominant role in the metabolic pathway, indicating that its potential role for glucuronidation-related factors, such as gene polymorphism, drug-drug interaction, etc., in changing the active and toxic effect of nobiletin and that it should be paid more attention in further development.
