Objective To study the effect of octreotide on patients with postoperative acute adhesive small bowel obstruction. Method In this study, 87 patients with postoperative acute adhesive small bowel obstruction were divided into 2 groups: experimental group (46 patients) and control group (41 patients). Patients in the control group were treated with routine therapy, including gastrointestinal decompression, intravenous infusion, antibiotic and enema. Patients in the experimental group were treated with routine therapy plus somatostatin analogue (octreotide) 0.1 mg. ih q8 h. for 72 hour. The alleviation of abdominal symptom and sign and the possibility of surgical intervention are observed and compared.Results Compared to the control group, the obstruction in the experimental group alleviated significantly,the abdominal pain relieved, the amount of draining decreased, and the passage of gas was earlier.Conclusions Based on the routine therapy, the use of octreotide significantly relieves the symptoms of obstruction and shortens the course of conservative therapy.

AIM: To investigate lipoprotein lipase gene HindⅢ polymorphism and its relationship with serum lipids and apolipoprotein, serum HDL subclasses in patients with hyperlipoidemia. METHODS: Lipoprotein lipase gene HindⅢ polymorphism was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The subclasses of serum HDL in 152 hyperlipoidemia patients and 128 healthy subjects were determined by two-dimensional gel electrophoresis conjunction with immunodetection method. RESULTS: H+H+ genotype and allele H+ in hyperlipoidemia and control groups were both the highest. In hyperlipidemia group, H+H+ genotypes tended to be higher than that in control group, while H+H- and H-H- genotypes were significantly lower (P

Background: Iliac vein compression syndrome (IVCS) is an important cause of deep vein thrombosis, but the incidence of IVCS is still unclear. The purpose of this prospective study was to determine the incidence of IVCS in an asymptomatic patient population and to evaluate the risk factors in patients with and without IVCS. Methods: From October 2011 to November 2012, a total of 500 patients (228 women and 272 men; mean age of 55.4 ± 14.7 years) with no vascular?related symptoms were enrolled in this study. Computed tomography was performed to evaluate all patients. The degree of venous compression was calculated as the diameter of the common iliac vein at the site of maximal compression divided by the mean diameter of the uncompressed proximal and caudal left common iliac vein (LCIV). We compared the stenosis rate of the common iliac vein in women and men according to age and followed up patients to evaluate outcomes. Results: The mean compression degree of the LCIV was 16% (4%, 36%); 37.8% of patients had a compression degree ≥25% and 9.8% had a compression degree ≥50%. There was a significant difference between men and women in the LCIV compression degree (9% [3%, 30%] vs. 24% [8%, 42%]; U = 4.66, P < 0.01). In addition, the LCIV compression degree among younger women (≤40 years) was significantly different compared with that in older women (>40 years) (42% [31%, 50%] vs. 19% [5%, 39%]; U = 5.14, P < 0.001). Follow?up was completed in 367 patients with a mean follow?up of 39.5 months (range, 6–56 months). The incidence of IVCS in the follow?up period was 1.6%. Stenosis rate and the diameter of the site of maximal compression correlated with the incidence of IVCS. Multivariable Cox regression analysis showed that the stenosis rate was an independent risk factor of IVCS (Wald χ2 = 8.84, hazard ratio = 1.13, P < 0.001). Conclusions: The incidence of IVCS was low and correlated with the stenosis rate of iliac vein. Preventative therapy may be warranted for common iliac vein compression in patients at an increased risk of venous thromboembolism, especially patients with a higher iliac vein compression degree.

Objective To establish a rat model of coal-burning-borne fluorosis,and to observe the expression changes of bone morphogenetic protein-2 (BMP-2) and bone morphogenetic protein-3 (BMP-3) in the serum of rat treated with different dose of fluoride and different treatment duration.Methods A total of 120 clean grade SD rats(body mass between 80 to 120 g) weaned for 4 weeks were randomly assigned into four groups,which were control,low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,respectively,and 30 rats in each group (female 15,male 15).All of the rats were fed with coal drying corn from fluorosis area.Ten rats were killed by femoral artery bleeding 30 d,90 d and 180 d after exposed to fluoride,respectively.Serum BMP-2 and BMP-3 level was tested by enzyme-linked immunosorbent assay (ELISA).Results ①Results of BMP-2:after exposed to fluoride for 90 d and 180 d,the differences of serum BMP-2 level between groups were statistically significant(F=385.08,173.98,all P ＜ 0.01).In low-dose fluorid,medium-dose fluorid and high-dose fluorid groups,the expression of serum BMP-2 at 90 d[(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] and 180 d[(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89)μg/L] was higher than that of control group[(12.54 ± 1.29),(7.53 ± 0.97)μg/L,all P ＜ 0.05],and the level of BMP-2 increased with increasing dose of fluoride (all P ＜ 0.05).Within each group,the difference of serum BMP-2 was statistically significant(F =55.42,511.58,686.35,671.64,all P ＜ 0.01).The expression of BMP-2 in each group at 90 d [(12.54 ± 1.29),(18.80 ± 0.43),(22.22 ± 0.85),(25.14 ± 0.69)μg/L] was higher than that at 30 d[(11.75 ± 1.15),(11.42 ± 1.07),(11.38 ± 0.92),(11.15 ±1.03)μg/L,all P ＜ 0.05].The expression of BMP-2 in each group at 180 d[(7.53 ± 0.97),(7.98 ± 0.68),(8.97 ± 0.78),(15.04 ± 0.89) μg/L] was lower than that at 90 d.②Results of BMP-3:the difference between groups was not statistically significant at every experimental stage(F =0.7215,1.2951,0.0964,all P ＞ 0.05).Conclusions Longer excessive fluoride intake stimulates the expression of BMP-2 in rats,but with prolonged fluoride intake,the stimulation becomes weak.The effect of fluoride on BMP-3 is not as sensitive as that on BMP-2.

Objective To evaluate the efficacy of preoperative regional intra-arterial chemotherapy (RIAC) in the treatment of resectable pancreatic head carcinoma. Methods The clinical data of 50 patients with resectable pancreatic head carcinoma who had been admitted to the Research Institute of Pancreatic Diseases of Fudan University from December 2006 to July 2007 were retrospectively analyzed. Patients were randomly divided into2 groups (n =25 in each group): patients in group A were treated with preoperative RIAC followed by regional pancreaticoduodenectomy, and patients in group B were treated with surgical procedure routinely. The lymphatic metastases in the 50 specimens of pancreatic head carcinoma were detected by histological examination with hematoxylin and eosin (HE) staining, and lymphatic micrometastases were detected by immunohistochemical method with staining of cytokeratin AE1/AE3 in 10 specimens with negative HE staining of the lymph nodes in each group. Results There was no significant difference in the incidence of complications, the length of hospital stay and the 1-, 2-year survival rates between the 2 groups (χ2 = 0.12, 2.88, P > 0.05). The incidence of positive lymph node metastasis in group A was 7.1% (52/734), which was significantly higher than 22.1% (118/532) in group B (χ2 = 60.01, P < 0.05). The incidence of lymphatic micrometastasis was 9.4% (30/319) in group A, and 9.1% (23/252) in group B, with no statistical difference between the 2 groups (χ2= 0.01, P > 0.05). Conclusions Preoperative RIAC is helpful in improving the prognosis of patients with resectable pancreatic head carcinoma by reducing the incidence of lymphatic metastasis and decreasing tumor stage.

Objective To discuss the clinical effects of hemiarthroplasty for the treatment of intertrochanteric comminuted fracture in aged patients.Methods From June 2006 to June 2010,91 cases with intertrochanteric comminuted fractures were treated by hemiarthroplasty using Zweymtüller long-stem cementless implant.There were 35 males and 56 females,with an average age of 81.2 years (range,75-94 years).There were fresh fractures in 75 cases and old fractures in 16 cases.According to classification of Evans-Jensen,there were 36 cases with type Ⅲ fracture and 55 with type Ⅳ.Osteoporosis was graded by Singh index,and there were 51 cases with level Ⅲ and 40 with level Ⅱ.The interval between injury and operation was 2-10 d (average,3.5 d).Results The surgery lasted 30-50 min (average,39 min).The blood loss was 320-610 ml (average,405 ml).The hospital stay was 14-21 d (average,16.5 d).Two cases who experienced with the infection of the respiratory system after operation,recovered through routine treatment.Thirty-seven cases were followed up for 15 to 38 months (average,24.5 months).According to the Harris score,the overall rate of excellent or good result was 83.8％ (31/37).Conclusion Hemiarthroplasty using Zweymüller long-stem cementless prosthesis is reliable option for intertrochanteric comminuted fracture in the aged patients.
