Objective To detect the expression of selenium binding protein 1 ( SBP1 ) in gastric cancer cell line SGC7901, BGC823, normal gastric epithelial cell line GES-1, gastric cancer tissues and normal gastric tissues, explore the relationship between SBP1 and pathologic features, and discuss the feasibility of SBP1 as an diagnostic marker of gastric cancer. Methods The clinical data of 135 patients with gastric cancer who were admitted to Zhongnan Hospital of Wuhan University from 2006 to 2007 were retrospectively analyzed. The expression of SBP1 in the gastric cancer tissues and 16 cases of normal gastric tissues were detected by immunohistochemistry. The mRNA and protein expressions of SBP1 of SGC7901, BGC823 and GES-1 were determined by Western blot and RT-PCR. All data were analyzed by using chi-square test and one-way analysis of variance.Results The mRNA expressions of SBP1 in BGC823 and SGC7091 were 0. 120 ± 0. 020 and 0. 133 ± 0. 015,respectively, which were significantly lower than 0. 907 ± 0. 015 in GES-1 ( F = 2106. 462, P ＜ 0.05 ). The protein expression of SBP1 in BGC823 and SGC7901 were 0.253 ±0.015 and 0.273 ±0.015 ,respectively, which were significantly lower than 0.877 ±0.025 in GES-1 ( F = 1026. 758, P ＜0.05 ). A strong positive reaction of SBP1 was observed in 3 cases of gastric cancer tissues and 16 cases of normal gastric tissues. The decrease of the protein expression of SBP1 was correlated with clinical stages of the patients ( x2 = 12. 629, P ＜ 0.05 ), rather than the sexes, ages, tumor histological types, tumor differentiation, infiltration depths and lymph node metastasis (x2 =2. 142, 0.860, 1.838, 5.001,4.858, 1.994, P＞0. 05). Conclusions The decrease of SBP1 expression could be used as a marker in diagnosing gastric cancer. Down-regulation of SBP1 expression may play an important role in the genesis and prognosis of gastric cancer.

Objective To investigate the cause, the clinical manifestation, the diagnosis and the treatment of subacute thyroiditis. Methods The medical history, clinical characteristics, laboratory data, nuclear medicine tests and treatment of 76 cases of subactue thyroiditis were analyzed. Results Subacute thyroiditis was more common in women than men, and 76 3% cases with subacute thyroiditis occurred during 30～49 years old. Almost all cases were characterized by enlargement of the thyroid with pain and tenderness, 49 cases of which showed that radioiodine uptake was low with increased serum thyroid hormone levels. 25 cases were treated with prednisone, 23 cases were treated with intrathyroid injection of dexamethasone, 23 cases were treated with intrathyroid injection of dexamethasone and triamcinolone, all recovered well, and 5 cases underwent operation incorrectly. Conclusions Confirmation of subacute thyroiditis should put emphasis on a complete medical history, physical examination and necessary tests. Nuclear medicine tests play an important role in diagnosis of subacute thyroiditis, and the diagnostic drug treatment or fine needle aspiration biopsy may be performed in suspected cases. Glucocorticoid is the best medicine for treating this kind of disease. There is no need for operation therapy of subacute thyroiditis.

Objective:To investigate the changes of hyoid position and pharyngeal airway before and after sagittal split ramus osteotomy (SSRO) of skeletal mandibular prognathism. Methods:Sixteen severe skeletal mandibular prognathism cases(Class Ⅲ, 5 males and 11 females) were chosen. Pre and post operation lateral cephalograms analysis reflecting pharyngeal airway and position of the hyoid bone was performed. Results: ① After SSRO, the width of airway decreased significantly. ② The distance between the mandible and the hyoid bone was also decreased significantly. No significant differences were found regarding measurements of the hyoid bone to the cranial base in male patients. Conclusion: The distance from the mandible to the hyoid bone and the width of airway were decreased significantly after SSRO. It suggests that the tongue and airway might be reformed functionally to new environments following SSRO surgical treatment.

Guided by the innovation theory and ideology, the authors'hospital saw to it that the main line of innovative progress ran through the entire process of its development and set up a management engineering framework for innovation in six chief aspects. It managed to achieve “three firsts”, viz. the first to put forward in the domestic medical industry the suggestion of taking strategic actions so as to promote the construction of a clean and honest administration in the hospital; the first among hospitals of the armed forces to cultivate an “experimental plot” that partook of no money earmarked for national defense; and the first among large general hospitals at home to develop into a non profit hospital without government subsidies. It also attained remarkable results in the fight against SARS.

Objective To investigate the value of spiral CT for the diagnosis and treatment of congenital anorectal malformations (CARM). Methods Thirty children with CARM underwent lateral upside-down plain film in abdomen and spiral CT scanning in pelvic cavity before surgical operation. The distance between rectal blind end and anal fossa in two imaging modalities was measured. The correlation between the measurement results in two imaging modalities was compared with operational results. Sacral deformation was diagnosed according to 3D reconstruction of CT images. Results The measurement results obtained from CT were correlated positively with those of operation (r=0.99, P<0.01). CARM combined with curved sacrum was diagnosed in one child. No correlation was found between the measurement results of X-ray and operation (r=0.31, P>0.05). Conclusion Spiral CT scanning can accurately describe the atresic level of rectum and malformation of sacrum. It can provide reliable evidence for surgeon to choose the best surgical method and to judge prognosis.

To analyze the reasons of injuries during surgical practices and explore the hazards and the corresponding preventive measures. The surgical interns don't receive enough training of injury prevention. They don't pay enough attention to the occupational prevention and are not skilled in operation, which causes high rate of sharp edged instrument injuries. Therefore, a perfect plan of education, training and treatment must be made to reduce the occupational injuries and blood sourced diseases.

Objective To investigate the clinical effects of sodium aescinate adjuvant in treatment with tibial plateau fracture. Method According to the principle of random draw, 160 cases of tibial plateau fractures patients were divided into observation group and control group, each had 80 cases. All cases were given the improved bilateral plate internal ifxation with conventional interventions, besides, the observation group were added intravenous infusion of sodium aescinate after surgery. Results The differences of operative time, blood loss and clinical fracture healing time between two groups were not signiifcant. After intervention, the overall incidence of complications with arthritis, deep vein thrombosis, joint stiffness and joint instability in observation group were signiifcantly lower than that in control group, but the value of joint activity with the HSS values were signiifcantly higher(P<0.05). The plasma TNF-αlevels between two groups before the intervention was not signiifcant, and the values were signiifcantly decreased after the intervention (P<0.05), and had signiifcant differences between the two groups (P<0.05). Conclusion Sodium aescinate has good effect on prognosis in treatment with tibial plateau fractures, the mechanism may be related to reducing the level of plasma TNF-α.

Objective To investigate the anti-tumor effects of a combination of Kanglaite injection (KI) and photodynamic therapy (PDT) on human pancreatic cancer SW1990 xenograft in nude mice.Methods The animal model of human pancreatic cancer was developed by suturing small pieces of SW1990 tumors into the dorsum of nude mice.60 rats were randomly divided into six groups:group A ( control group without treatment),group B ( receiving 1.25g/kg KI via the tail vein prior to PDT and continuously for 10 days),group C (receiving 2.5g/kg KI via the tail vein continuously for 10 days),group D (PDT group,2 mg/kg Photosan 48h prior to laser irradiation),group E ( group B + group D),group F ( group C + group D)with 10 rats in each group.The tumor sizes were measured twice per week.The mice were sacrificed on the 14th day of PDT treatment.The tumor was took out and weighted and the tumor inhibitory rate was analyzed.Results The tumor volumes of group A to F were 9550.08±52.46)mm3,(519.71±46.44)mm3,(405.29±38.67 ) mm3,( 199.27±37.37) mm3,( 107.47±14.13 ) mm3 and (75.58±12.53 )mm3,the weight of group A to F were (0.82±0.08)g,(0.77±0.06)g,(0.61±0.06)g,(0.41±0.05)g,(0.28±0.04)gand (0.16±0.04)g,respectively.The tumor volumes and tumor weights of the two combined groups were significandy smaller than those in the other groups (P＜0.05).The combination group of 1.25 g/kg KI increased the tumor inhibitory rate from 50% in PDT group to 65.9%.The combination group of 2.5 g,/kg KI increased the tumor inhibitory rate to 80.5%.Conclusions KI had attenuated effect on PDT therapy,and the combination of KI and PDT could significantly inhibit the tumor growth.

Objective To evaluate surgical therapy for recurrent rectovaginal fistula.Methods In this study.two patients were treated by endorectal advancement flap repair and one patient was treated by vascular pedicled segment of small bowel.Results All patients were cured and followed up from 4 to 20 months.During the period of follow-up there was no recurrence.Conclusions The procedures and timing of operation are important factors for a successful repair.Both the endorectal advancement flap and patch of intestine provide an effective methods in repairing recurrent rectovaginal fistula.

Objective To retrospectively analyze our experience of embolization of ruptured intracranial aneurysms during the period of cerebral vasospasm (CVS). Methods Thirty-seven patients with ruptured intracranial aneurysms were embolized with electrolytic detachable coils during the period of CVS (days 4 to 14). Group A included the 14 patients with angiographic CVS and group B included 23 patients without angiographic CVS. All except 2 patients were transferred to our department during the CVS period. Glasgow outcome score (GOS) was evaluated 3 months after the treatment. Results Twelve patients in group A successfully received the aneurysm embolization and treatment of the CVS with intraarterial papaverine injection and balloon angioplasty. GOS in 3 months was good recovery in 7 patients, moderate disability in 2, severe disability in 1, and dead in 2, respectively. Embolization failed in 2 patients because the microcatheters could't pass the spasmodic parent arteries. All the aneurysms in group B were successfully embolized. GOS were good recovery in 18 patients, moderate disability in 2, severe disability in 2, and dead in 1, respectively. There was no intraprocedural aneurysmal rupture but with 2 thromboembolic events. No rebleeding occurred during the mean 11 months follow-up. Conclusions The so-called “period of CVS” isn′t always associated with CVS in angiograpy. Embolization of ruptured intracranial aneurysms during the period of pure CVS doesn′t carry an increased risk. Both the aneurysms and CVS can be treated during the single procedure. It can reduce the rebleeding rate in hospital and improve the prognosis of the patients with CVS.
