OBJECTIVETo compare the efficacy among acupuncture based on "jin" theory, regular acupuncture and western medication.

METHODSA total of 95 cases, by using incomplete randomization method, were divided into a "jin" theory acupuncture group (32 cases), a regular acupuncture group (31 cases) and a medication group (32 cases). Patients in the "jin" theory acupuncture group were treated with acupuncture based on "jin" theory which included the "gather" and "knot" points on the affected side: positive reacted points, Fengchi (GB 20), Tianrong (SI 17), Tianyou (TE16) and Yiming (EX-HN14) as the main acupoints, while the Ermen (TE 21), Tinggong (SI 19) and Tinghui (GB 2) and zhigou (TE 6) as the auxiliary acpoints; the treatment was given once a day. Patients in the regular acupuncture group were treated with regular acupuncture at Tinggong (SI 19), Tin- ghui (GB 2) and Ermen (TE 21) and other matched acupoints based on syndrome differentiation, once a day. Pa- tients in the medication group were treated with oral administration of betahistine mesylate, three times a day. Ten days of treatment were taken as one session in three groups, and totally 2 sessions were given. Visual analogue scale (VAS), tinnitus handicap inventory (THD), and tinnitus severity assessment scale (TSIS) were evaluated before and after treatment; also the clinical efficacy was compared among three groups.

RESULTSThere are 5 drop-out cases du- ring the study. After the treatment, the VAS, THI and TSIS were improved in three groups (all P < 0.05); the VAS, THI and TSIS in the "jin" theory acupuncture group were lower than those in the regular acupuncture group and medication group (P < 0.05, P < 0.01). The total effective rate was 90.0% (27/30), 80.0% (24/30) and 63.3% (19/30), which was higher in the "jin" theory acupuncture group (P < 0.05, P < 0.01).

CONCLUSIONThe acupuncture based on "jin" theory is superior to regular acupuncture and western medication for cervical tinnitus.

Objective To propose a modified graph cut algorithm under the elliptical shape constraint to segment the ultrasonogram of cervical lymph nodes. Methods Since cervical lymph nodes were usually oval-shaped, the prior of the elliptical shape information, which was expressed as a distance function, was used to constrain the cut cost of the graph cut algorithm. The initially segmented contour was fitted with an ellipse to get the constraint. Then a certain segmentation was obtained by minimizing the cut cost function constrained with the elliptical prior. This procedure was iterated until it to be convergent. Results Under the same user input, this algorithm successfully segmented nodes on the low contrast ultrasonograms, while the traditional graph cut approach failed. For 20 ultrasonograms, with the average minimum Euclidean distance (AMINDIST) measure and the Hausdorff distance measure, these two distances between contours manually delineated by the radiologist and those segmented by this algorithm were far less than the distances resulted from the traditional graph cut algorithm. Conclusion It is indicated that utilizing the elliptical shape constraint prior can obviously improve the graph cut algorithm for segmenting cervical nodes on ultrasonograms.

Objective To propose prevention and management of vascular crisis according to cause analysis, and improve the survival rate of digital replantation. Methods The vascular crisis of 132 digits of 98 cases were observed during intraoperative. The replantation was performed under different time and different conditions. The causes of vascular crisis, and propose effective prevention and management of vascular crisis were restrospective analysis. Results From March 2006 to June 2007, 35 amputated digits occurred vascular crisis during intraoperative, 19 amputated digits occurred during postoperative. After using warm physiological saline and injecting the papaverine partly, we proceed operations research with regard to the non-catabatic amputated digits. As result 58 digits survived, the achievement ratio was 89.2%. From July 2007 to March 2009, 10 amputated digits occurred vascular crisis during intraoperative,5 amputated digits occurred during postoperative. After non-surgical treatment, we performed operations research regard to the non-catabatic amputated digits. After blood supply recover, we imbed PCA pump into flex tendinous sheath to avoid the occurrence of vascular crisis postoperative. As result 66 digits survived, the achievement ratio was 98.5%. postoperative 9 cases out of fullow-up, 89 cases follow up ranged from 6 to 8 months. Recovery of the hand function was good. Conclusion Good and adequate anesthetic and an appropriate ambient temperature during operation are important factors to prevent occurrence of vascular crisis in digital replantation. Paying enough attention to these factors can effectively improve the survival rate of replantatian.

Objective To promote preventive and therapeutic measures for osteoporosis by investigating the prevalence of low bone mineral density (BMD) in connective tissue disease patients who were taking corticosteroid and identify the associated risk factors of osteoporosis.Methods Thirty-eight female patients who had connective tissue diseases and were taking corticosteroid in PU MCH rheumatology outpatient clinic were studied and followed up from Oct 2006 to April 2007.Lumber spine and right femoral bone mineral density were determined bv dual energy X ray absortiometry (DEXA).Clinical information was obtained from a questionnaire of history and medical records.Duration and accumulative dosage of glucocorticoid intaking.menopause time were obtained retrospectively.Correlation analysis between BMD and clinical information was conducted.Results ① In 38 patients,23 (61%) patients showed a normal BMD,10 (26%) were osteopenia,3 (8%) were iu the osteoporotic range,while 2 patienLs (53%) had fragile fracture.② Compared with patients with normal BMD,subjects with low BMD had significantly older age,longer period after menopause and higher accumulated dose of corticosteroids.③ Postmenopausal women had significantly lower BMD in lumber and hip than premenopausal women.④ Either of vertebral and right hip BMD correlated negatively with the accumulated dosage of cortieosteroids by simple linear regression.⑤ The correlation between BMD and accumulated dosage of corticosteroids improved after correcting for the effect of age by partial correlation analysis (Pearson partial vertebral r=-0.8,P=0.009;right hip r=-0.3,P=0.010).⑥ A stepwise multivariate linear regression model was constructed to explore the relationship between the different clinicsl factors studied and a low BMD.Two statistically significant variables were menopause status (P=0.0000) and a higher steroid accumulated dosage (P=0.008).Conclusion Low BMD is common in connective tissue disease patients receiving corticosteroid.Risk factors for low BMD are postmenopause.duration and the accumulated dosage of glucocorticosteroid.The high prevalence of low BMD implies that more attention should be paid to the prevention and treatment of osteoporosis and fractures in connective tissue disease patients who are taking corticosteroids.

Objective: To investigate the influence of the expression of retinoic acid receptor genes on the development of B cells in lymph nodes of young children. Method: In situ hybridization was performed on the frozen section of lymph node of young children (≤age 5 ). Six digoxin labeled antisense RNA probes for retinoic acid receptors mRNA(RAR?、?、?、RXR?、?、?)were used. The expression and distribution of retinoic acid receptor genes in lymph nodes and their influence on the differentiation and maturation of B cell were observed. RT-fluorescent PCR was also used to observe the expression levels of retinoic acid receptor genes and their relation to the maturation of B cells. Results: In situ hybridization showed all the 6 retinoic acid receptor genes were expressed in lymphocytes and reticular cells of lymph node, and the distribution was widespread. RT fluorescent PCR also showed a varying expression of 6 retinoic acid receptor genes in lymph node among different age children, but lower in children younger than 1 year, and then increased gradually with the development of immune system. Conclusion: The expression and regulation of retinoic acid receptor genes may take part in the ontogenesis of B cells, and play a key role in the regulation of retinoic acid and enforce the anti-infective immunity in children.

Objective: To investigate the effect of retinoic acid on the differentiation and development of B lymphocytes, and explore the mechanism of vitaminA in increasing the production of antibodies. Method: In vitro cultured cells from children’s normal mesentery lymph nodes, before and after administration of retinoic acid or retinoic acid antagonist, the changes of cell surface markers were analyzed by flowcytometry to observe the differentiation and maturation of B cells. Results: During culture in vitro, the percent of mature CD19+IgM+ B cells increased and relatively immature CD19+IgM- B cells decreased gradually, and the changes were especially obvious at 48 h. The administration of retinoic acid further increased the percent of CD19+IgM+ B cells, and the enhancement was markedly at 24 and 48 h (P
