Fifty cases of mild - moderate cerebrovascular dementia selected by referring to the diagnositic criterion DSM- I -R for cerebrovascular dementia (VaD) established by America Society of Psychoneurology issued by WHO were randomly divided into Shen Tong Capsule treatment group (30 cases) and hydergine treatment group (20 cases). Modified Mental State Examination (MMSE) and Blessed Behavior Scale (BBS) were used to calculate changes of marks before and after treatment for assessment of therapeutic effects. Results show that Shen Tong Capsule has therapeutic effect on key symptoms and clinical behaviour of mild - moderate disturbance of intelligence, with the total effective rate of 86. 67%. Differences of accumulated marks in both MMSE and BBS before and after treatment in the treatment group are superior to those of the control group respectively.

BACKGROUND: Transplantation of microencapsulated rabbit Schwann cells in the rat spinal cord can relieve inflammatory reaction, promote spinal cord regeneration, but the precise mechanisms remain unclear. OBJECTIVE:To observe basic fibroblast growth factor (bFGF)expression and movements recovery following transplantation of microencapsulated rabbit Schwann cells in rat spinal cord. METHODS: The sciatic nerves taken out from rabbits wore digested with mixed enzyme and were made into Schwann cells suspension. Then we used air-jet method to make Schwann cells microcapsule. Using the same method, empty microcapsule was made. Sprague Dawiey rats were randomly divided into cell group, empty microcapsule group and microcapsule group. Conducted by hemisection injury of spinal cord,the rats in cell group,empty microcapsule group and microcapsule group were implanted with gelatin sponge with 10μL Schwann cells suspension, gelatin sponge with 10 μL empty microcapsule and 10 μL microencapsulated Schwann cells. Normal group was left intact. After operation, we observed hindlimb movements recovery in rats with the Basso, Beattie, and Bresnahan (BBB) scale. Meanwhile,a set of sections were stained immunohistochemically for bFGF expression, another set of sections wore stained for hematoxylin-eosin and Nissal. RESULTS AND CONCLUSION: After spinal cord injury, rat right hindlimb affected paralysis immediately. At 7, 14 and 28 daysfollowing transplantation,motor function in rat hindlimb was significantly recovered, and the BBB scores were significantly higher in microencapsulated schwenn cells than in cell and empty microcapsule group (P < 0.05 or P < 0.01). bFGF positive products were mainly distributed in cytoplasm of the spinal neuron and nucleus of neuroglical cell. The numbers of bFGF positive glial cells mainly appeared surrounding the spinal cord injured site on days 1, 3, 7 and rose to its peak on day 3 and began to appear in neuronal calls on day 14. The number of bFGF positiv cells in microcapsule group was significantly superior to that in cell group and empty microcapsule group. From then on, the bFGF expreSsion was significantly decreased in each group. These indicated that transplantation of microencapsulated Schwann cells can inhibit the immunological rejection after xenotransplantation, suppress inflammatory reaction, improve the expression of bFGF, increase hindlimb movements recovery and spinal cord regeneration after spinal cord injury.

OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

Objective To summarize the 18F-FDG PET/CT findings of LCH in children,and explore its value in the diagnosis of LCH.Methods PET/CT imaging and clinical data of 13 patients (6 males,7 females;average age (3.0±2.3) years) with LCH confirmed by histology before treatment from August 2011 to December 2015 in Xin Hua Hospital were retrospectively analyzed.Results All 13 patients have different degrees of bone destruction with increased metabolism,the common lesion sites were craniofacial bone,spine,limb long bones,ribs/chest/shoulder blade and pelvic bone.Lymph node lesions which manifested lymph node enlargement with increased metabolism were found in 10 cases,and the SUVmax was 4.0±1.3.Diffuse FDG uptake in spleen was found in 10 cases.There were 4 cases with liver lesions,3 with lung lesions,1 with high metabolic nodules in muscle,1 with orbital lesions and 1 with intraspinal high metabolic nodules.Conclusion 18F-FDG PET/CT could display the distribution and activity of LCH,and plays an important role in the diagnosis and systemic evaluation of LCH.

AIM:To study the effect of captopril on calcineurin and NF-?B p65 in the signal transduction pathway of the cardiovascular remodeling in hypertensive rats.METHODS:Using a animal model of hypertension induced by abdominal aortic banding,the rats were treated with captopril for 10 weeks.The blood pressure was observed with a tail cuff method.The heart weight and heart weight/body weight were measured.The expression of calcineurin and NF-?B p65 were studied by using immunohistochemistry.RESULTS:After treated with captopril,the blood pressure of the model rats was decreased(P

Objective To evaluate the application of sentinel lymph node biopsy in surgical operation for clinical stage N0 differentiated thyroid carcinoma.Methods One hundred and six patients who were diagnosed clinical stage N0 differentiated thyroid carcinoma in Department of Mammary Gland Thyroid Surgery of Qingdao Women and Children's Hospital between Jan.2012 and Jan.2013 were reviewed retrospectively.Carbon nanoparticles were used to trace sentinel lymph node in the surgery,the patients were divided into the dissection group (46 cases included 2 cases whose sentinel lymph nodes were not detected) and the non dissection group (60 cases) based on the rapid pathological results.The operation index,complications incidence and short-term outcomes were compared.Result The operative time,intraoperative blood loss and the faulty excision of parathyroid gland in dissection group is much higher than those in non dissection group (P ＜0.05).The incidence of provisionality hypoparathyroidism in dissection group is much higher than those in non dissection group (P ＜ 0.05).There were no permanent hypoparathyroidism and damage of laryngeal nerve in the two groups.Postoperative outpatient follow up was 30 months,no significant differences were seen in local regional recurrence rates(6.5％ vs 10％) between the two groups (P ＞ 0.05).There were no distant metastasis occurred in the two groups.Conclusions Lymph node metastasis can be found by sentinel lymph node biopsy,it is helpful for us to decide whether dissect central lymph node or not.Carbon nanoparticles is safe,which is helpful to protect the parathyroid gland.

With the popularization of ureteroscopy, ureteral avulsion has become a common complication of urological surgery in recent years. In the study, we reviewed the clinical management of 2 patients who underwent emergency ureterostomy and selective operation of ileoureteral substitution, emergency repair and selective operation of Boari-flap ureteroneocystostomy respectively. After 22 and 17 months of follow-up, no ureter stricture were found, and hydronephrosis were relieved compared with preoperative in both.

OBJECTIVETo investigate the effect of distraction osteogenesis (DO) in the treatment of severe mandibular micrognathia with severe obstructive sleep apnea and hypopnea syndrome (OSAHS).

METHODS19 cases of severe mandibular micrognathia with OSAHS were treated by DO. All the patients received PSG and MSCT examination before and after DO to evaluate the therapeutic effect and changes in the upper airway.

RESULTSAccording to the evaluation standard, 17 cases were cured and 2 cases improved markedly. The sagittal distance and area, transverse distance and area of the upper airway increased markedly after DO. The volume of upper airway increased from (15 572.03 +/- 3 370.11) mm3 to (21 182.69 +/- 4 533.15) mm3.The airway change happened mainly in velopharyngeal region and the lingopharyngeal region, but not in the laryngopharyngeal region.

CONCLUSIONSDO can treat severe mandibular micrognathia patients with OSAHS effectively by enlarging the volume of upper airway,especially in the velopharynx and glossopharyngeum region. The MSCT plays an effective and important role.
