Purpose:To investigate the pathogenesis,diagnos is and treatment of hashimoto's disease(HD) complicated with papillary thyroid c ancer (PTC ). Methods:Clinical data of 12 cases of HD complicated with PTC un dergoing surgery were analysed retrospectively and followed-up for one half to 8 years. Results:In this series papillary thyroid cancer occurred in 25 % (12/48) in patients with HD, but correct preoperative diagnosis was obtained i n 3 (25%) of 12 cases.All patients had thyroid nodules and received thyroidectom y,3 cases underwent functional cervical clearance of lymph nodes. All patients w ere followed up for 6 months to 8 years and there was no death , no recurrence and no metastasis. Conclusions:HD can develop into PTC .The clinical diagnosis of coexistence of HD and PTC is still difficult. The key to diagnosis and rational treatment includes detailed understanding its clinical features, routine examin ation of serum antibodies and ultrasonography, selected scintigraphic thyroid s can or FNAB and finally quick frozen pathologic section in operation. HD complic ated with PTC should be treated surgically.Intraoperative frozen section diagnos is should be performed routinely so that HD complicated with PTC can be diagnose d.The operation procedure should be individualized.All patients should be given small dosage of thyroxine.

Objective:To investigate the remodeling of alveolar bone and the changes of roots after an-terior retraction with maximum anchorage by analyzing CBCT data from adult cases.Methods:The sam-ple comprised 48 incisors and 24 canines from 12 patients (18 to 40 years of age)with problems of ma-xillary protrusion or upper arch protrusion.CBCT scans were exposed before and after treatment,and la-teral cephalometric images as well as multiple planar reconstruction images were reconstructed.Tracing superimpositions of sagittal sections and three-dimensional reconstructions were done for qualitative analy-sis.For all maxillary anterior teeth,changes of root length,alveolar bone height and labial-palatal thick-nesses at different levels were evaluated.The average of measurements taken by the same tester in three times was processed by SPSS 17.0 statistical package.Results:In 6 of the 12 cases,alveolar thickness became thinner on labial side [apical area:(-0.64 ±1.18)mm]while thicker on palatal side [apical area:(0.93 ±2.0)mm]and the root length decreased[(-0.95 ±0.79)mm].In the other 6 cases, the incisors’alveolar bone became thicker on labial side [apical area:(2.12 ±1.46)mm]while thin-ner on palatal side [apical area:(-2.88 ±0.58)mm]and the loss of root length was obvious[(-2.12 ± 1.43)mm].In all the 12 cases,the canines’alveolar bone became thinner on labial side especially on the apical level [(-0.27 ±1.86)mm]while greatly thicker on palatal side [apical area:(6.40 ± 6.00)mm]and the root resorption was slight [(-1.12 ±1.19)mm].For all the anterior teeth,the height of alveolar bone reduced around them after retraction.Conclusion:When the root apical moved more palatally,more root resorption would occur and the alveolar bone would get thicker on labial side but thinner on palatal side and thinner as a whole after anterior retraction with maximum anchorage.In the vertical direction,the height of the alveolar bone generally decreased on all sides and decreased the most on the palatal side.

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.

Objective: To investigate the laboratory,clinical and economic results of early postoperative enteral nutrition(EEN) in patients with gastrointestinal cancer.Methods: 120 patients with gastrointestinal cancer were randomly divided into three groups: EEN,early postoperative parenteral nutrition(PN), and traditional nutrition(CON)groups.The 1/3 and 2/3 target volumes were administered on the first and second postoperative days(1POD,2POD),and the full volume was given from 3POD to 8POD in EEN and PN groups.The routine formula was offerd from 1POD to 8POD in CON group.The nutritional and immune parameters were detected one day before surgery and 9POD, and the clinical and economic results were collected in three groups.Results: The levels of ALB,TF,PA,CD3,CD4,CD4/CD8 were significantly higher in EEN and PN groups than those in CON group(both P＜0.01),and the CD3,CD4,CD4/CD8 were better in EEN group than those in PN group(P＜0.05).The side effects of EEN group were similar to those of PN group(P>0.05). The recovery of bowel function was quicker in EEN group than that in PN and CON groups(both P＜0.05).The complication rate, cost of nutrition support,and cost of complication treatment were lower in EEN group than those in PN group(P＜0.05, P＜0.01, P＜0.01).Although the cost of nutrition support was lowest but the complication rate and cost of complication treatment were all highest in CON group.Conclusion: EEN is better in immune function, recovery of bowel function,complication rate, and cost-effectiveness than those in PN, and from our multiple angular viewpoints EEN is the first choice for patients with gastrointestinal cancer.

Objective To explore the establishment and implementation of nursing quality evaluation system in department of orthopedics. Methods Randomly 527 patients hospitalized in the department of orthopedics from December 2011 to December 2012 were selected and assigned into the control group, where a traditional evaluation system was used. Another 528 patients hospitalized from April 2013 to June 2014 as the observation group, where orthopedics specialist evaluation system was used. The two groups were compared in terms of hospital evaluation accuracy, observation accuracy, accuracy rate of specialist intervention complications, the qualified rate of nursing records and patient satisfaction. Result The hospital evaluation accuracy, observation accuracy, the accuracy rate of specialist intervention complications, the qualified rate of nursing records and patients satisfaction of the observation group were significantly higher than those of the control group (P<0.01) and there was no incidence in two groups. Conclusion The establishment of orthopaedic nurse quality evaluation system can make up the shortage of traditional evaluation system and improve the quality of the orthopaedic nursing management.

Objctive To search for the therapeutic method of children's nephrotic syndrome.Methods Sixty-six cases oe children's nephrotic syndrome were randomly divided into 2 groups,impulsion group (34 cases) and control group (32 cases). Dexamethasone (1．5~3 )/mg (kg?d) added into (100~150)ml 10%GS solution, intravenous drip in impulsion group, one time a day, totat 3 days, the fourth day stoped. The fifth day started again and used one time evcry two days, total 6 times. Prednisone(1．5~3)mg/(kg?d) were taken next day and total 4 weeks, then grandually decreased the dose. Only prodnisone was used in control group, the method and dose were the same as impulsion group.Results Complete remission. partial remission inefficacy ere 23, 7 and 4 cases respectiye1y in impulsion group and 22, 5 and 5 cases respectively in control group, the effective rates of the 2 group are 88．23%and 84．38% (P＞0．05). The times of state of illness stabilization are respectively 11．3?7．2 and 10．48?6．34 months in the 2 groups. The side effect of impulsion group is bigger than that of control group.Conclusion Children's primary nephrotic syndrome should be treated for 8 weeks by routine hormone induction therapy, if no remission, impulsion therapy could be used.

Objective To investigate the plantar pressure distribution of the injuried limbs and the healthy side after the operation for Pilon fracture. Methods 31 patients with Pilon fractures were tested with Footscan USB2 system, including the maximum force and impulse of 10 zones of the feet 1 year after surgery. Results Compared with the contralateral feet, the maximum force reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and it increased under the fourth, and fifth metatarsal bone (P<0.05) of the injured feet. The impulse reduced under the the first metatarsal bone, medial heel, and lateral heel (P<0.05), and increased under the fifth metatarsal bone and midfoot (P<0.05). Conclusion The load decreased on the heel and medial forefoot, and increased on the lateral forefoot of the injured limbs after Pilon fracture, while the lateral forefoot and midfoot tend to be injured.
