OBJECTIVE: To observe the transcranial Doppler ultrasonography and X-ray changes of cervical vertigo patients caused by cervical instability before and after the manipulation treatment in supine position. METHODS: Sixteen cervical vertigo patients who underwent supine manipulation treatment were reviewed retrospectively. After the treatment, the changes of transcranial Doppler ultrasonography of cervical vertebral artery and X-ray of cervical spine were observed. RESULTS: Before the treatment, the mean blood flow velocity of vertebral artery was (48.6+/-3.1) cm/s, much higher than that of the normal group (P<0.05), the means of the horizontal displacement of C3,4 and C4,5 were (3.18+/-0.42) mm and (3.46+/-0.26) mm respectively. After the treatment, the blood flow velocity and the C3,4 horizontal displacement decreased significantly (P<0.05). The effective rate of the manipulation treatment was 100%. CONCLUSION: The manipulation treatment is an effective method for cervical vertigo patients caused by cervical instability, and the effect is correlated with the improvement of the blood flow of cervical artery and the restoration of cervical stability.

Objective To explore the effect of heterosexual interaction training on rehabilitation in first-episode schizophrenic patients. Methods 246 patients of first-episode schizophrenic were divided into the study group and the control group with 123 cases in each group at random. Both groups were treat-ed with conventional pharmacotherapy under the orders of physicians in hospital. For the study group,both the male patients and the female patients took part in entertainment treatment activities,eating and interaction training together during the day, then they lived separately at night. Two groups were evaluated with BPRS and ITAQ before treatment and at the 2nd, 4th, 6th, and 8th week after treatment. Results The BPRS scores of the study group were significantly lower than the control group after 4th, 6th,and 8th week. The ITAQ scores of the study group were significantly higher than the control group after 4th, 6th,and 8th week. Conclusions The application of heterosexual interaction training in schizophrenic patients can alleviate illness condition, improve treatment compliance and rehabilitation.

Objective To discuss the prevention and treatment of bile duct injures io the gallbladder bed during laparoscopic cholecystectomy(LC).Methods A retrospective analysis was made on clinical features,treatment,and curative effects of 15 cases of bile duct injures in the gallbladder bed out of 2 032 cases of LC from January 1997 to December 2004.Results There were 5 cases of acute attack of chronic calculous cholecystitis and 10 cases of chronic atrophic calculous cholecystitis.The location of injury was at the branches of the right hepatic ducts in 8 cases and at aberrant bile ducts in 7 cases.The injury was treated with titanium clipping in 8 cases,primary suture in 5 cases,and open surgery of bile duct repair in 2 cases because the injury was relativly large and the site of injury was near the trunk of the right hepatic duct.Postoperatively,bile leakage happened in 1 case and was cured by drainage for 5 days.Follow-up surveys for 6~36 months (mean,23 months) showed free of symptoms and no jaundice or cholangitis.Conclusions Surgical dissection closely near the gallbladder wall when mobilizing the gallbladder is the key to preventing bile duct injuries in the gallbladder bed during laparoscopic cholecystectomy.Prompt detection and proper management of the injury have satisfactory curative effects.

Objective To study cortactin function in cancer cell endocytosis.Methods We applied cortactin siRNA interference to MDA-Mb-231,a human breast adenocarcinoma cell line in which cortactin was over-expressed,and introduced anti-cortactin immunoreagents into the cells with BioPorter system to interfere with cortactin function in vivo.Capture-ELISA assay was used to measure transferrin uptake.We used immunoblot assay to assess the effect of cortactin knock-down and immunoflurescence microscopy to examine the effect of cortactin down-regulation on transferrin uptake.Results Interference of cortactin function in cells resulted in impairment of transferrin endocytosis.Transferrin fluorescent intensity in cytoplasm in cortactin siRNA treated-cells was significantly reduced in comparison to that of mock-treated cells.Less than 50% of cells subjected to cortactin siRNA treatment had normal transferrin uptake.Endocytosis in MDA-Mb-231 cells introduced with cortactin antibodies was impaired as well,showing a 30%～ 60% reduction in transferrin uptake.Conclusion Crtactin,an actin-binding protein,plays an essential role in cell endocytosis.

Objective To explore agreement between parent-child report of self-rating scale of systemic family dynamics (SSFD),as well as factors that may influence the agreement.Methods SSFD was used to investigate the agreement between parent and child reports on family dynamics in a sample of 639 Chinese children aged 10 to 18 years from Mainland China,and possible influence factors.Results The results showed that there was significant difference between parent-child report of SSFD.The parents had significant lower score than their children at atmosphere,individuation and disease conception and had higher score at system logic (all P＜0.01).But the two still had significant positive correlation (correlations ranging from 0.15 to 0.38),indicating a low to moderate agreement between them(r=-0.15-0.38,all P＜0.01).The age factor was related to parent-children agreement on SSFD.Parent-child agreement was highest for family atmosphere,followed by individuation,system logic and disease conception.The age factor was related to parent-child agreement on SSFD.Conclusions Both parents' and children's reports of SSFD can be used to assess family dynamics,however,attention should be payed to the affection of parent-child report's difference and age factor to the results.

Objective To inactivate Death-associated protein kinase 1 gene (DAPK1) by transfecting complementary methylated oligonucleotides and studies its effect on the proliferation of myelogenous leukemia cell line K562. Methods Methylated oligonucleotides complementary to DAPK1 gene promoter were transfected into K562 cells by Iipo2000. Methylation specific PCR (MSP) and Reverse transcription PCR (RT-PCR) were applied to detect DAPK1 gene promoter methylation status and its mRNA expressions respectively. MTT was used to detect the proliferation of K562 cells pre- and post- oligonucleotides transfection. Results DAPK1 gene promoter in non-treated and control groups were unmethylated with detectable mRNA expressions, but it became methylated with inhibited mRNA expressions after methylated oligonucleotide transfection. Proliferation in methylated oligonucleotide treatment group was significantly higher than that in non-treated and control groups. Conclusion Complementary methylated oligonucleotides could inactivate DAPK1 gene and inhibit its expression in K562 cells, which could promote its proliferation.

Objective To explore the MRI findings of enthesitis in peripheral ankylosing spondylitis (AS). Methods We retrospectively reviewed the MRI obtained from 13 patients with clinically-diagnosed peripheral AS. MRI finding attributable to enthesitis could be visualized as tendon or ligament enthesitis, bone marrow edema (BME), synovitis, bursitis, tenosynovitis. Results MRI findings of knee showed enthesitis in 8 knees, mainly involved in the insertions of the quadriceps tendon at the upper patellar pole , the patellar ligament at the lower patellar pole and the tibial tubercle, BME in 8 knees, synovitis in 5 knees, bursitis in 3 knees, and tenosynovitis in 4 knees. MRI findings of ankle showed enthesitis in 3 ankles, involved in plantar insertion into calcaneus and Achilles tendon insertion into the calcaneus, BME in 1 ankle, and tenosynovitis in 3 ankles. Conclusion The lower extremities are more often involved in peripheral AS than the upper extremities. MRI characteristic of enthesitis may contribute to the diagnosis of peripheral AS early combined with HLA-B27.
