OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.

RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.

CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.

Objective To master the prevalence trend of Kaschin-Beck disease in Xinghai county (Shanglujuan and X.ialujuan village of Tangnaihai township) from 2003 to 2008 in order to understand changes of selenium level of internal and external environments. Methods According to monitoring method on national Kaschin-Beck disease,we carried out epidemical investigation,clinical examination and X-ray photograph on school children aged 7-12 in Xinghai county,a monitoring region,and collected samples of hair and grain. The content of selenium was detected by 2,3-naphthalene fluorescence. Results From 2003 to 2008,in Shanglujuan village,the prevalence rate of clinic examination was fluctuating between 0(0/34)-17.14%(6/35); the detectable rate of X-ray examination was fluctuating between 11.11% (3/27)-20.59% (7/34),the prevalence rates of metaphysis and extremities were fluctuating between 0 (0/27)-13.21%(7/53) and 2.63% (1/38)-11.43% (4/35). In Xialujuan village,the prevalence rate of clinic examination was fluctuating between 2.94% (1/34)-13.33% (6/45); the detectable rate of X-ray examination was fluctuating between 26.67% (12/45)-43.63%(24/55),the prevalence rate of metaphysis and extremities were fluctuating between 8.33% (6/72)-26.47% (9/34) and 13.33% (6/45)-38.18% (21/55). The selenium contents in hair samples were (139.92±92.27),(134.98±63.77)μg/kg respectively in Shanglujuan and Xialujuan village in 2003; the selenium contents in grain samples were (12.90± 7.18),(14.58±9.90)μg/kg respectively in Shanglujuan and Xialujuan village in 2005. Conclusions The prevalence state of Kaschin-Beck disease in national monitoring region is rigid and pathogenetic factors of Kaschin-Beck disease are active. Selenium levels of internal and external environments are low in this region.

Under the guidance of the concept of fast tract surgery (FTS), peri-operative managements including pre-operative, intra-operative and post-operative treatments can be optimized to accelerate the rehabilitation of surgery patients. Post-operative recovery of gastrointestinal functions is one of the key links of FTS, in which Chinese medicine has certain features and advantages over it. Current assessments on post-operative gastrointestinal functions recovery include clinical and laboratory assessments, but there is still no industrial assessment received by all. The current situation of post-surgery assessment of peri-operative gastrointestinal functions was studied in this paper, and the research orientation of this field was analyzed and prospected.

OBJECTIVETo study the expression of heme oxygenase-1 (HO-1) in dental pulp tissue and to find out the relationship of distribution and function of HO-1.

METHODS30 pulp tissues were obtained from clinically extracted human healthy premolars and third molars. The expression of HO-1 in dental pulp was detected by means of SABC immunohistochemical technology.

RESULTSHO-1 immunoreactivity was observed in vascular endothelial cells, odontoblasts and some fibroblasts cells.

CONCLUSIONThe distribution of HO-1 in normal human dental pulp suggests that HO-1 may play an important role in pulp flow regulation, dentin production and its calcifying; it also may play some roles in dental pulp cells metabolism and differentiation.

Human gut microbiota plays a key role in the development of obesity. Intestinal flora can regulate energy absorption and nutrition metabolism, increasing the energy harvesting from diet. Alteration of gut flora produces excessive lipopolysaccharide, which, when absorbed into the blood, can induce inflammatory reactions and promote the high-fat diet-associated obesity and metabolic syndrome. Intestinal flora increase visceral fat deposition by lowering the expression of Fiaf in intestinal mucosa. Different immune status also affects the intestinal flora.The gut microbiota is hypothesized to be an environmental factor that contributes to obesity; by interacting with factors such as host and diet, it adjusts the energy metabolism. Antibiotics or probiotics may alter the composition of intestinal microflora and improve the metabolic syndrome, and thus provides new treatment options.

OBJECTIVETo investigate the therapeutic experience of gastrointestinal stromal tumors (GIST) and to analyze the pathological features and prognostic factors of GIST.

METHODSThe clinicopathological and follow-up data of 181 patients with GIST admitted in Renji Hospital between January 1999 and December 2007 were analyzed retrospectively. All the cases were grouped according to Fletcher's risk scheme. Life table and COX regression model were used to evaluate the prognostic factors.

RESULTSOut of 181 tumors, 107(59.1%) were located in stomach, 51 (28.2%) in intestine and 23(12.7%) in colorectum or other sites. Distant metastases,including liver metastases were found in 7 patients intraoperatively. Tumor size ranged from 0.5 to 30 cm with the mean of 7.02 cm. The positive rate of CD117 was 94.5% (171/181) and that of CD34 was 86.2% (156/181). One hundred and seventy-six patients underwent complete resections, including multi-organ resections in 26 patients. The other patients underwent palliative operations. The 1-, 3- and 5-year overall survival rates of 181 patients were 95.2%, 87.9% and 78.5% respectively. Univariate analysis revealed age, tumor size, primary organ of tumor, mitotic count, Fletcher's classification and multi-organ resection were associated with survival rate. No significant difference of sex was existed among groups. COX hazard proportional model revealed that advanced stage and large tumor size indicated worse prognosis. Eight patients with high risk of recurrence and 3 patients with recurrence and metastasis were stable after receiving imatinib therapy.

CONCLUSIONSThe diagnosis of GIST depends on endoscope and CT. Fletcher's classification is simple and effective to evaluate GIST behavior and prognosis. Surgical resection is still the main therapy for GIST and targeted therapy will play a more important role for prognosis in the future.

OBJECTIVETo explore the mid-term surgical results of arterial revascularization for femoro-popliteal arterial occlusive disease (lesion type C and D).

METHODSFrom January 2005 to February 2009, 191 arterial bypass had been performed on 170 patients (21 cases bilateral). There were 108 male and 62 female, age ranged from 45 to 85 years old with an average of 67 years old. The operative indication was claudication in 78 cases, rest pain in 62 cases, ischemic ulcer in 19 cases, and distal tissue necrosis in 11 cases. Arterial angiography were performed on all cases. According to TASC II document, type C lesions were seen in 127 limbs, type D lesions were seen in 64 limbs. Autogenous greater saphenous vein bypass in situ were done on 15 limbs, autogenous greater saphenous vein bypass reversed in 20 limbs, revascularization with artificial prosthesis in 128 limbs, composite grafts consisting of a prosthetic conduit with a distal venous segment in 28 limbs.

RESULTSThere were no 30-day mortality. Follow-up periods ranged 6 to 36 months with an average of (24 + or - 6) months. Seventy-three cases were lost during follow-up periods, follow-up rate was 57% (109/191). Primary patency rate was 84.4% (92/109). The patency rate was 88.2% with artificial prosthesis, 70.8% with greater saphenous vein (in situ or reversed). Secondary patency rate was 89.9%.

CONCLUSIONSArterial revascularization with artificial prosthesis is main treatment for diffused superficial femoral artery occlusive disease (TASC II type C and D lesion) with satisfied surgical results.
