Objective:To study the morphological characteristics of temporo-mandibular joint with high angle vertical skeletal pattern in adult females with class II skeletal type.Methods:41 CBCT films of adult females (20 normal controls;21 skeletal class II high angle subjects)were collected.The position of and form of condyle,form of fossa and joint spaces were measured by Mimics 17.0 soft-ware.Results:Compared with the control group the condyles in high angle patients located more posterior.The joint fossae were lower. The angles of posterior joint node bevels were smaller.The condyles were shorter,thinner and tipped more anteriorly.The position of the conyles were more anteriorly.Conclusion:Class II skeletal type adult females with high vertical skeletal patterns have different forms of fossae,different positions and forms of condyle compared with the normal controls.

Objective To explore the effects of angelica naphtha on the withdrawal signs and norepinephrine neurotransmitter in uorphine-dependent rats.Methods 72 SD rats were randomly divided into control group,model group,clonidine group and three angelica naphtha groups (80,40 and 20 mg/kg).Rats were received gradualy increasing doses of morphine to produce physical dependence.Withdrawal symptoms were evaluated by Ryuta Tomoji score.The level of norepinephrine and normetanephrine(NMN) were tested by enzyme-linked immunosorbent assay(ELISA).Results The scores of withdrawal signs were (4.00± 3.29),(30.13±4.41),(18.96± 4.43),26.04±4.13),(22.33±4.60) and (19.00±3.47),respectively.The morphine withdrawal signs were reduced by angelica naphtha in a dose-dependent manner(P＜0.01),also significantly reduced the level of NE and NMN and the ratio of NMN/NE in the nucleus ceruleus and prefrontal cortex(all P＜0.01).Conclusion Angelica naphtha alleviates the withdrawal synlptons in morphine-dependent rats,which may be related to the inhibition of excessive turnover of norepinephrine neurotransmitters in the nucleus ceruleus and prefrontal cortex.

Objective To understand the clinic usage of TCM decoction pieces in the First Affiliated Hospital of Xi’an Jiaotong University (hereinafter referred to as our hospital).Methods By using Microsoft Office Excel software, the medicine doses, classification of functions and clinic application of the TCM decoction pieces, which were among the top 50 most frequently used TCM decoction pieces were analyzed.Results In 2014, 60% of the top 50 most frequently used TCM decoction pieces in our hospital exceed the medicine dosage inChinese Pharmacopoeia. According to the functions, the top 3 TCM decoction pieces were medicine for reinforcing deficiency, clearing heat and promoting qi, respectively. Medicine for reinforcing deficiency was mainly used in gastroenteropathy, menopathy and nephropathy. Medicine for clearing heat was mainly used in gastroenteropathy, menopathy and infection of the upper respiratory tract. Medicine for promoting qi was mainly used in gastroenteropathy, tumor and disease of cardiovascular system.Conclusion TCM decoction pieces in our hospital exceed the medicine dosage in Chinese Pharmacopoeia, which requires attention. The top 3 TCM decoction pieces are respectively medicine for reinforcing deficiency, clearing heat and promoting qi, whose clinic applications are basically rational.

Objective To investigate the reliability of the morphologic measure of the iliotibial band (ITB) with musculoskeletal ultrasound imaging. Methods 20 healthy young subjects were measured with the musculoskeletal ultrasound imaging of the thickness of bilateral ITB at the levels of the femoral condyle by 2 testers, and one of the testers measured again 3-5 days later. The intraclass correlation coefficient (ICC) and minimum detectable change (MDC) were calculated, and the thickness of ITB in both sides was compared. Results The ICC of test-retest was 0.89 (R) and 0.85 (L), and it was 0.82 (R) and 0.84 (L) of inter-testers. The MDC was 0.41-0.51 mm. There was no significant different between right and left sides for the ITB thickness among healthy subjects (P=0.97). Conclusion Musculoskeletal ultrasound imaging is a feasible and reliable to measure the ITB thickness among young healthy subjects.

Spinal cord injury has changed the function of human body and the way of life, and reduced the reserve capacity of the organs of various systems, which exceeded the body's repair ability itself, and overlapped with physiological aging and premature senescence appeared. This paper reviewed recent studies and analyzed the relation of the injured age, the chronological age, number of years after injury with dysfunction, predicted the function changes of them, and identified the factors related with their quality of life.

Qi-Gui-Yin (QGY) compound, which composes of five herbal medicines of Astragalus membranaceus (Fisch.) Bge., Angelica sinensis (Oliv.) Diels, Lonicera japonica Thunb., Artemisia annua L., and Polygonum cuspidatum Sieb.et Zucc., which is able to treat antibiotic-resistant bacteria with antibiotics, and also to delay or even reverse the bacterial resistance producing. However, QGY compound is a complex mixture. And it is very difficult to elaborate its material foundation. Therefore, chemical constituents in five herbal medicines were summarized through searching of the related literatures. And then, 170 kinds of bioactive ingredients were classi-fied in order to provide evidences for the study on chemical constituent of QGY compound and identify its mate-rial foundation of delaying drug resistance .

Objective To investigate the clinical and biologic characteristics of acute myeloid leukemia (AML) with 6q deletions (6q-). Methods Two cases of with 6q deletions (6q-) were here described, and all the AML cases with 6q- found in the literature were reviewed. Results Two cases were diagnosed with AMLMt and AML-M2, respectively. Myloloid markers were positive on the leukemia cells in both cases, none of them expressing lymphocytic antigens. The karyotype of these patients were 46,XX,del(6)(q21q25),t(4; 7)(q10;q10)[3]/46,XX,del(6)(q21q25)[2]/46,XX[25], and 46,XX,del(6)(q23),t(7;11)(p15;p15)[5]/46,XX,t(7;11)' (p15;p15)[9]/46,XX [6]. Until now, 28 cases (including present 2 cases) of AML with 6q- have been documented in the world literature. Many of the AML patients with 6q -have additional chromosomal abnormalities. The breakpoints on 6q- were widely distributed from q12 to q27, mainly involved in the 6q21-23 region. Overall, the AML patients with 6q- were associated with an unfavorable clinical outcome, with a poor response to chemotherapy and a shorter duration. 6q-clone may itself confer a malignant clinical outcome. The 6q- found in some AML cases may associate with leukemogenesis via an activation of an oncogene other than myb or deletion of an antioncogene located in the long arm of chromosome 6. Conclusion Deletion of 6q is a very rare event in AML. AML with 6q- had distinct biologic features and a. poor clinical outcome.

Objective To explore the indication and the functional advantages of the high-flexion posterior stabilized (PS) rotating-platform mobile-bearing (RP-MB) total knee system. Methods A prospective randomized, controlled trial was performed. Osteoarthritis was the indicators for total knee arthroplasty.From Feb. 2009 to Apr. 2009, 75 patients (94 knees) were randomly assigned to to receive either a highflexion PS, RP-MB total knee system(PFC sigma RPF) or a standard one (PFC sigma RP). There were no statistical difference in the baselines, the preoperative scores of the Hospital for Special Surgery (HSS) and the knee range of motion (ROM) of both groups. The functional status were assessed with Hospital for Special Surgery and the ROM of the knee at the postoperative 1, 6, 12, 18 months. The satisfaction rates were assessed at the postoperative 18 months. The radiographic measurements were t assessed at the postoperative 3days and 3, 6, 12, 18 months. Results A total of 70 participants (87 knees) completed the 18-month followup. At the time of the final follow-up, the average Hospital for Special Surgery knee score was 92.4±5.0points in the standard group and 94.7±7.0 points in the high-flex ion group. The difference was not statistically significant(P ＞0.05). The average maximal flexion was 131.9±14 degrees in the high-flexion group and 123.0±15.3 degrees in the standard group. There was a statistical difference. But it was not enough to confirm our hypothesis that the difference should be higher than 10 degrees. Moreover, the satisfaction rate were 100% in both groups, and no statistical significant difference was found. Conclusion No significant differences were found between standard and high-flexion posterior-stabilized rotating-platform mobile-bearing total knee prostheses in terms of clinical outcomes or range of motion.
