Clinical data were analysed in 19 patients with propylthiouracil (PTU)-induced antineutrophil cytoplasmic antibody associated vasculitis. Among them, 17 patients (89.5%) were diagnosed as Graves′ disease originally. The duration of PTU therapy in 18 patients was more than two years. Multi-organ involvement was common, with 15 patients (78.9%) involved in kidneys and 8 patients (42.1%) involved in lungs. The prevalences of arthralgia, skin rash and fever were also high. All patients withdrew PTU, and some with severe organ involvements received prednisone and immunosuppressant.

Objective To test the efficacy of low-frequency electrical acupoint stimulation plus rehabilitation training in improving swallowing function after stroke. MethodsEighty dysphagic stroke patients were randomly allocated into 2 groups of 40.Patients in the experimental group received low-frequency electrical acupoint stimulation plus 2 courses of rehabilitation training.Control group patients received the same protocol,but the electrical stimulation was not over acupoints.Their swallowing function was assessed using the Kubota water drinking test.ResultsAfter treatment,both groups showed significantly lower Kubota scores compared with pre-treatment.Prepost test difference was 1.25 ± 0.78 in the experimental group and 0.70 ± 0.72 in the control group,a significant difference.The total recovery rate in the experimental group was 87.5％.In the control group it was 55％.The improvement in swallowing function was significantly better in the experimental group.Conclusion Both groups showed a significant improvement in swallowing function,but low-frequency electrical acupoint stimulation increased the effectiveness of the rehabilitation training.

Objective To investigate the experience of endoscopic mini-invasive therapy for residual lesions of peripancreatic necrotizing infection with choledocoscopy-assisted debridement technique, and to explore its clinical application value. Methods 71 patients with postoperative surgical drainage and accompanied with residual focus were collected. Choledochoscope was inserted via the drainage sinus, and the focus was observed and necrotic tissue was removed under direct choledochoscopic vision. Results Of the 71 patients who underwent this procedure, 64 were cured (success rate, 90.1%); 3 patients withdraw from treatment due to economic reasons; 4 patients received open surgery after 1 ～ 3 times of choledocoscopy-assisted debridement. The 64 cured patients received 2 ～ 9 times of choledocoscopy-assisted debridement with a mean of 5.1 times. 87.5% patients needed 4 ～ 6 times of procedures. The healing time was 18 ～ 125 days (average 71.3 days). Hemorrhage occurred in 3 patients and digestive tract fistula occurred in 2 patients and were resolved with non-operative management. Conclusions With the help of postoperative established surgical drainage channel, choledochoscopy-assisted debridement could be considered as a safe and effective miniinvasive treatment for residual focus of peripancreatic necrotizing infection, and is worth of clinical application.

Objective To investigate the difference of apparent diffusion coefficients (ADCs) changes in three major salivary glands after gustatory stimulation using two different stimuli. Methods Thirty healthy volunteers were examined with a 1.5 T MR unit. A diffusion-weighted MR imaging (MR DWI) sequence was performed once at rest and continuously repeated 13 times after gustatory stimulation using a commercially available lemon juice and vitamin C tablets in the same volunteer by using self-controlled method. The subsequence of two stimuli was random. In addition, the salivary flow rates at rest and after stimulation were measured. Characteristics and differences in ADCs curves of three salivary glands before and after stimulation between two stimuli were analyzed. Comparison of maximum ADCs, maximum ADCs increase rates (IRs) and times to maximum ADCs(Tmax) between two stimuli was performed by using independent-samples t test. Correlation analysis between rest salivary flow rates and rest ADCs, the maximum salivary flow rates and ADCs after stimulation, the maximum salivary flow IRs and ADC IRs after stimulation were performed by using Pearson correlation test. Results In lemon juice stimulation group, the mean ADCs mostly showed a steady increase to peak values during the first DW MRI scan after stimulation in all glands, followed by a gradually decrease fluctuating slightly around the baseline values. In vitamin C stimulation group, the mean ADCs were significantly increased in all glands during the first DW MRI scan after stimulation, followed by a gradual upward trend till peak values. In lemon juice stimulation group, the mean Tmax of submandibular and sublingual glands[(184±122)s, (345±232)s, respectively] were significantly earlier than those[(454 ± 301)s, (528 ± 297)s, respectively] in vitamin C stimulation group (t=-3.517 and-2.548 respectively, P<0.01 for all). The mean maximum ADCs of three glands in lemon juice stimulation group[(1.05 ± 0.12) × 10-3 mm2/s, (1.22 ± 0.10) × 10-3 mm2/s and (1.26 ± 0.21) × 10-3 mm2/s, respectively] were all lower than those in vitamin C stimulation group[(1.13±0.13) ×10-3 mm2/s, (1.32±0.25) × 10-3 mm2/s and (1.57 ± 0.36) × 10-3 mm2/s, respectively], and the differences in parotid and sublingual glands between two groups were significant(t=-2.894 and-3.681 respectively, P<0.01 for all). The mean maximum ADC IRs of three glands in lemon juice stimulation group[(11.35±4.07)%, (8.81±5.40)%, (34.08±21.66)%, respectively] were significantly lower than those[(17.80 ± 12.72)%, (18.16 ± 18.93)%, (67.49 ± 46.04)% , respectively] in vitamin C stimulation group (t=-2.252,-2.330 and-3.432 respectively, P<0.05 for all) . In two groups, the mean maximum ADC IRs of parotid and submandibular gland were all significantly lower than sublingual gland (t=-5.994 and-6.443 respectively, P<0.01 for all). No correlation was observed between ADCs and salivary flow rates, ADC IRs and salivary flow rate IRs in two groups (P>0.05). Conclusion MR DWI with transient stimulation using lemon juice is more stable for evaluating the physiologic changes of salivary glands in vivo.

The hG -CSF cDNA was cloned by RT-PCR and confirmed by sequencing, which contains the full length of hG-CSF encoding region and parts of 5 '、3' non - coding region. Then the hG - CSF retroviral vector pLGSN was constructed by orientationally inserting the hG-CSF cDNA into the EcoRI/XhoI cloning sites of pLXSN vector. Packaged with CRE and CRIP packaging cell lines which are considered to be unlikely to produce helper viruses, the final pLGSN retrovirion titer reached 1. 1 ?106 CFU/ml. During constitutive passaging, the CRIP - LGSN cell clone produced relatively stable tilers of pLGSN retrovirion, ranging from 6. 8?105CFU/ml to 1. 1?106CFU/ml. By infecting the murine fibroblast cell line NIH3T3 with pLGSN retrovirion, a cell clone designated as NIH3T3 -G -CSF was obstained, secreting 168U/ml G-CSF . The integration and expression of hG-CSF gene in this cell clone were confirmed by Southern and Northern blotting analyses. Western blotting has also detected specifically the hG-CSF protein in the condensed supernalants from NIH3T3-G-CSF cells . After packaging the hG-CSF-secreting fibroblasts with collagen and implanting them into synergenic mice peritoneally , we detected a certain levels of G-CSF in the sera of mice, which suggested the implanted NIH3T3-G-CSF fibroblast cells could constitutively express and release hG-CSF in vivo. Our data showed the constructed hG-CSF retroviral vector could be used to further investigate the fibroblasl-mediated hG-CSF gene therapy .

Objective To investigate the feasibility of ultrasound-guided percutaneous drainage for the treatment of peripancreatic abscess. Methods The clinical data of 36 patients with peripancreatic abscess who were admitted to the General Hospital of the Chengdu Military Command were retrospectively analyzed. All the puncture sites were designed according to the region, range and shape of the abscess, and then the angle and the direction of the needle penetration were determined according to the spatial relationship between the puncture site and the abscess. Finally, the drainage tubes were placed under the guidance of the ultrasound. Results The technique was successfully performed on all the patients, and 33 patients were cured with the cure rate of 92%.The mean healing time was 37 days. Three patients were converted to laparotomy because of the unsatisfied therapeutic effects. Enterocutaneous fistula was detected in 3 patients after the surgery and they were cured after receiving nonoperative management. All patients were followed up for 3-48 months, and neither residual abscess nor recurrence was detected. Two patients were complicated with type one diabetes, one with dyspepsia, two with gallstone, and they were cured by symptomatic treatment. The body weights of 27 patients were increased compared to those before the operation. Conclusion Ultrasound-guided percutaneous drainage is effective for the treatment of peripancreatic abscess.

AIM:Atherosclerotic calcification is highly linked with plaque instability and cardiovascular events .Adenosine monophosphate-activated protein kinase ( AMPK) has been involved in the pathogenesis of various cardiovascular disease .The contributions of AMPKαsubunits to the development of atherosclerotic calcification in vivo remained unknown .We hypothesized that AMPKαsubunits may play a role in the development of atherosclerotic calcification .METHODS: Atherosclerotic calcification was generated by 24-week fed of western diet in ApoE-/-background mice .Calcification was evaluated in aortic roots and innominate arteries of ApoE-/-mice or in mice with dual deficiencies of ApoE and AMPKαsubunits globally ( AMPKα1 and AMPKα2 ) , or vascular smooth muscle cell ( VSMC)-specific or macrophage-specific knockout of AMPKα1 with atherosclerotic calcification pone diet . The mechanism of AMPKα1 in regulating Runx2 was further explored in human aortic VSMC .RESULTS: Ablation of AMPKα1 but not AMPKα2 in ApoE-/-background promoted atherosclerotic calcification with increased Runt -related transcription factor ( Runx2 ) expression in VSMC compared with ApoE-/-mice.Conversely, chronic administration of metformin, which activated AMPK, markedly reduced ath-erosclerotic calcification and Runx2 expression in ApoE-/-mice but had less effects in ApoE-/-/AMPKα1 -/-mice.Furthermore, VSMC-but not macrophage-specific deficiency of AMPKα1 in ApoE-/-background promoted atherosclerotic calcification in vivo com-pared with the controls .AMPKα1 silencing in human aortic VSMC prevented Runx 2 from proteasome degradation to trigger osteoblastic differentiation of VSMC .Conversely , activation of AMPK led to Runx 2 instability by inducing its small ubiquitin-like modifier modifi-cation (SUMOylation).Protein inhibitor of activated STAT-1 (PIAS1), the SUMO E3-ligase of Runx2, was directly phosphorylated by
AMPKα1 at serine 510, to enhance its SUMO E3-ligase activity.Ablation of PIAS1 serine 510 phosphorylation inhibited metformin-in-duced Runx2 SUMOylation, and subsequently prevented the effect of metformin on reducing oxLDL-triggered Runx2 expression in hu-man aortic VSMC.CONCLUSION:Deficiency of AMPKα1 in VSMC increases Runx2 expression and promotes atherosclerotic calcifi-cation in vivo.AMPKα1 phosphorylates PIAS1 to enhance Runx2 SUMOyalation and subsequent degradation .
