Thyroid-associated ophthalmopathy(TAO)is an organ-specific autoimmune disease. A series of symptoms related to it cause serious harm to the physical and mental health of patients, and then seriously affect their quality of life. However, there is stilly lack of specific treatment methods at present. Even after effective treatment, it is difficult to fully recover the appearance changes. Therefore, it is very important to avoid or reduce the risk factors associated with the occurrence and progress of TAO. Hypercholesterolemia, as one of the potential risk factors for the occurrence and progression of TAO, has been concerned by more clinical researchers. Recent studies have found that statins can significantly reduce the incidence of ophthalmopathy and the risk of ophthalmopathy progression in patients with Graves disease. Based on the inflammatory pathological mechanism of TAO, statins may become a new hope to prevent and delay the occurrence and progression of TAO.

[Objective]To explore the curative effect of lumbar discogenic low back pain treated with posterior lumbar interbody fusion(PLIF)and transpadicular instrumentation.[Method]Thirty-six patients with lumbar discogenic low back pain were treated with disc excision,lumbar interbody fusion and transpedicular instrumentation.The clinical results were evaluated by pre-and post-operative VAS(visual analogue scale),and the fusion rates were evaluated by X-ray of the lumbosacral spine.[Result]The average period of follow-up was 16 months,ranging from 8 to 28 months.Low back pain basically disappeared in 33 patients treated with PLIF,mild back pain occurred in 3 patients;the VAS after operation decreased significantly in comparison with that of preoparation(P

Objective To investigate the clinical effect of surgical treatment for hilar cholangio-carcinoma. Methods The clinical data of 89 patients with hilar cholangiocarcinoma surgically treated in our hospital were retrospectively analyzed. They were divided into 3 groups: radical resection(group A,n=23),palliative resection (group B,n=44) and external drainage operation (group C,n=22). Complications,operative mortality,survival rate and posttreatment quality of lire were compara-tively analyzed among the 3 groups. Results The rate of complications was significantly higher in group A than in group C (P<0.05). There was no marked difference in operative mortality between group A and group B (P>0.05). The 1-,2-and 3-year survival rates and scoring of quality of life were remarkably higher in group A than in other 2 groups (P<0. 001 and 0. 05). Conclusion Radical re-section of hilar cholangiocarcinoma can improve the long-term survival and significantly enhance quality of life of the patients after operation. For patients receiving unradical resection, palliative surgical man-agement can improve the long-term survival and enhance quality of life.

AIM:It is suggested that the peptidergic nerves containing substance P(SP),calcitonin gene-related peptide(CGRP),vasoactive intestinal peptide(VIP),neuropeptide Y(NPY) and tyrosine hydroxylase(TOH) co-exist in bone tissues and distribute in the active bone metabolism area,indicating these peptidergic nerves are closely related with bone growth and development. In this study,the expression of neuropeptides in tibial callus of rats after brain injury was observed. METHODS:The experiment was conducted in the Experimental Animal Center of Guangxi Medical University from February to May 2007. ①130 male Wistar rats of 3-4 months old and 450-550 g were randomly divided into fracture group(n =60),brain injury plus fracture group(n =60) and control group(n =10). ②The right parietal bone of anesthetized rats was exposed,and bone window of 5 mm was opened 2 mm near median line,then moderate brain injury was made by sap pressure,and the rat models of tibial fracture were established. The fracture group was only subjected to cranial bone window,and the control group was not given any treatment. ③The distribution of neuropeptide in tibia and callus succession as well as fracture healing were observed by HE and immunohistochemical staining on postoperatively days 3,7,14,21,28,and 35 days. The callus area in brain injury plus fracture group and fracture group was detected by computed radiography(CR) at 14,21 and 28 days after operation. RESULTS:All 130 rats were involved in the result analysis. ①At early stage after brain injury,there were a quantity of fibrous callus and cartilaginous callus formation in brain injury and fracture group and many neuropeptides immunoreactive nerve fibers in callus were found. Strong immunoreactivites of CGRP,SP,VIP,NPY,TOH occurred to osteogenitor cells and chondroblast,which proliferated in thickened endothecium. ②In brain injury and fracture group on day 14,the chondrocyte group was enlarged and subperiosteum chondrocyte layer was thickened;on day 21,bone trabecula was significantly thickened,and cartilage islands were increased;on day 28,there were still quantity of fibrous callus and cartilaginous callus,and sparse woven bones surrounding chondrocyte groups. In fracture group,periosteal reaction was slight,and fibrous callus was few;osteogenesis in bone and cartilage occurred,but mainly in bone. Moreover,the fracture healing was remarkably later than brain injury and fracture group. ③Callus area in brain injury and fracture group was larger than that in fracture group on days 14 and 21(P

BACKGROUND: Loss of sacral slope has been shown to be an important anatomic basis for low back pain. The effect of sacral slope changes after lumbar fusion on pain relief remains unclear.OBJECTIVE: To analyze the variations of sacral slope and clinical significance at the early stage after posterior lumbar interbody fusion at L4-5.METHODS: Sixty patients with herniation at disc levels L4-5 and spinal stenosis (n=38) or lumbar spondylolisthesis at L4 (n=22) undergoing posterior lumbar interbody fusion were enrolled. All patients were followed up for 12-24 months to compare the sacral slop at baseline and postoperatively. The clinical outcomes were evaluated by MacNab criteria, and its correlation with age, sex and sacral slop variations was analyzed.RESULTS AND CONCLUSION: At 12-24 months postoperatively, the sacral slope in the two groups was significantly improved than that at baseline (P < 0.05), but there was no significant difference in sacral slop between two groups (P > 0.05). The age, sex and sacral slop variations showed no significant effects on the early clinical outcomes (P > 0.05).These results suggest that posterior lumbar interbody fusion can markedly improve the sacral slope in patients with spinal stenosis and lumbar spondylolisthesis at early period. Furthermore, age, sex, and sacral slope variations all show no obvious effect on postoperative early functional recovery.

Objective To develop a selective isolation media which has a high isolation ratio for Legionella.Methods We compared the growth of Legionella pneumonia on BCYE? plate (with DGVP), BCYE?(with GVPC) and BCYE? (with CCCV) by colony count and compared with BCYE? plate. The comparison of isolation ratio of Legionella pneumonia from air-conditions cooling water with 3 kinds of BCYE? plate containing different anti-reagents was performed.Results The results of colony count on BCYE? plate (with DGVP) and BCYE?(with GVPC) was identical with that on BCYE? plate at same concentration. But the result of colony count on BCYE? plate (with CCCV) was half of the former 2 kinds of plate. 5 strains of Legionella pneumonia isolated from 9 central air-condition cooling water were used by BCYE? plate (with DGVP) and BCYE? (with GVPC), while only 2 strains of Legionella pneumonia were isolated by BCYE? plate (with CCCV). Legionella pneumonia wasn′t detected by BCYE? plate.Conclusion BCYE? plate with antibiotics system of CCCV showed obvious suppression to Legionella pneumonia, and so that there was a low isolation ratio to Legionella pneumonia. But BCYE? plate with antibiotics system of DGVP and GVPC had a few suppression and showed a high isolatio ratio for Legionella pneumonia. Moreover, BCYE? plate with antibiotics system of DGVP and GVPC can effectively inhibit non-Legionella and increase isolation ratio of Legionella. They should be the first selection media for Legionella from environment and clinical samples.
