Objective To detect the expressions of proliferating cell nuclear antigen (PCNA), C-erbB-2, p53, estrogen receptor (ER) and progesterone receptor (PR) in order to explore the proper margin for breast conservative surgery on Chinese women. Methods We collected 40 resection specimens from breast cancer patients who had received radical surgery. Then we divided each specimen into primary tumor group and hyperplasia and gene expression characteristics of PCNA, c-erbB-2, p53, ER and PR were measured by pathological and immunohistochemical assay in the five groups. Results With the further distance from the primary tumor, the proportions of high-risk disease and positive gene expressions of PCNA, c-erbB-2 and p53 in paracarcinoma tissues gradually decreased (P<0.05). Higher risk and more positive expressions were related to paracarcinoma was no correlation of PCNA, ER and PR expressions adjacent to breast cancer with tissue differentiation and lymph node metastasis (P>0.05). a safe and appropriater region for breast conservative surgery.

Objective To introduce the method of reconstructing posterolateral complex injury of the knee with the autogenous middle 1/3 of biceps femoris tendon and gracilis and evaluate its short-term outcome. Methods There were 21 cases of posterolateral complex injury of the knee reconstructed with the middle 1/3 of biceps femoris tendon and gracilis from January 2003 to December 2006. There were 13males and 1 female at age range of 18-49 years ( mean 34.3 years). The reconstructed ligaments included popliteal tendon, lateral collateral ligament and poplitrofibular ligament. An autogenous folded gracilis tendon was extracted and placed through trastibial bony tunnel from anterolateral to the posterior condylar of the tibia to reconstruct the popliteal tendon. An autogenous folded middle 1/3 of biceps femoris tendon was fixed in the isometric bony tunnel of the femoral lateral condyle. The anterior half was used to reconstruct the lateral collateral ligament, and the posterior half to reconstruct the poplitrofibular ligament. The posterolateral stability of the knee was evaluated mainly through examination varus instability of knee and external rotation range of leg. Results All cases were followed up for average 26 months (6-24months). Lysholm score of the knee was (43 ± 2) points preoperatively and (90 ± 3 ) points half year after operation, with significant improvement. Conclusions PCL injury may result in functional deficiency of the injured extremity. While the autogenous middle 1/3 of biceps femoris tendon and gracilis can yield a stable knee with good function, mini-trauma and satisfactory clinical results in reconstructing the posterolateral complex of the knee joint.

Objective To determine the level and clinical significance of 5-hydroxytryptamine (5-HT) and intestinal fatty acid binding protein (iFABP) in patients of severe acute pancreatitis (SAP) with intestinal dysfunction. Methods The serum and urine in 42 cases of SAP with intestinal dysfunction were collected at day 1, 3 and 7 after admission, respectively. The numbers of bowel sounds were recorded. 20 health subjects were selected as the control. Results The numbers of bowel sounds in health subjects were 5.6 ± 2.3/min. The numbers of bowel sounds in SAP patients at day 1,3 and 7 were 2.3 ± 0.7/min, 1.7 ± 0.2/min and 3.1 ± 1.1/min, respectively;which were significantly lower than that in the control group (P < 0.01). The level of 5-HT in the control group was(86.7 ± 9.5)ng/ml, while the levels of 5-HT in the SAP patients at day 1, 3 and 7 were (112.0 ± 17.8) ng/ml, (130.5 ± 19.7) ng/ml, (107.9 ± 16.3) ng/ml. The level of urine iFABP in the control group was (90.5 ± 19.8) pg/ml, while the levels of urine iFABP in the SAP patients were (1250.2 ± 425.3) pg/ml, (1586.9 ± 523.4) pg/ml, (1154.6 ± 394.0) pg/ml. The levels of 5-HT and urine iFABP in the SAP patients all were significantly higher than those in the control group (P <0.01). The levels of 5-HT and urine iFABP in the SAP patients at day 3 were significantly higher than those in the day 1 and day 7, while there was no significant difference between the two groups. Conclusions Determination of serum 5-HT and urine iFABP in patients with early SAP could effectively evaluate the intestinal function, and it may have potential clinical significance.

Objective To investigate the therapeutic effect of Da-Cheng-Qi Decoction on gut dysfunction in patients with severe acute pancreatitis (SAP). Methods Forty-eight SAP patients complicated with gut dysfunction were randomly divided into two groups according to the number of admission, which were treatment group and control group. The therapy in t reatment group was Da-Cheng-Qi Decoction infusion through gastric tube (one paste/day, b. i. d), however the therapy of control group was normal saline infusion through gastric tube (the amount was the same as the former, b. i. d), and other management in the two groups was similar. The first passage of gas by anus and defecation after treatment was observed. Serum amylase, C-reactive protein (CRP), tumor necrosis factor (TNF)-α, interleukin (IL)-6 were examined before and one week after treatment;complications and mortality were compared between the two groups. Results The first passage of gas by anus and defecation in the treatment group was ( 12.3 ± 5.7 ) h and ( 24.8 ± 11.2 ) h, respectively, and shorter than ( 22. 1 ± 9.7 ) h and 46.2 ± 17.4) h of control group ( P <0.01) ;the numerical values of serum amylase, CRP, TNF-α and IL-6 one week after treatment were ( 120.3 ± 35.8 ) U/L, ( 10.8 ±2.0) ng/ml, (36.3 ± 5.8) U/L and (4.8 ± 1.0) U/L, which were significantly decreased when compared with the values before treatment, and these values were significantly lower than (267.2 ± 78.9 )U/L, ( 19.5 ± 2.7 ) ng/ml, (80.1 ± 9.0) U/L, ( 10.5 ± 1.2 ) U/L of the control group ( P < 0.05 ). The total complications and mortality of treatment group was 12.5% and 4.4%, respectively, which were significantly lower than those in the control group (37.5% and 25%, P <0.05). Conclusions Treatment with Da-Cheng-Qi Decoction in SAPpatients complicated with gut dysfunction was effective to reverse gut dysfunction and reduce total complications and mortality.

Objective To investigate the effect of Da-Cheng-Qi decoction on enteric functional disturbance in rats with acute experimental pancreatitis and its potential mechanism. Methods Seventy-two SD rats were randomly divided into sham operation group, acute pancreatitis (AP) group and Da-Cheng-Qi decoction treated group with 24 each. The AP model was induced by retrograde injection of sodium taurocholate (0.1 ml/100 g) into bitiopancreatic duet. Before modeling, the rats in treatment group received Da-Cheng-Qi decoction (2 g/100 g), and the rats in other two groups received 0.9% NaCl solution. The rats were sacrificed at 3, 6 and 12 hours with 8 each, and the blood samples were taken for detecting the level of amylase and the contents of 5-hydroxytryptamine (5-HT) by enzyme-linked immunosorbent assay. The colonic tissues 10 cm apart from trans-ligament incluing jejunum, terminal ileum and sigmoid colon were collected for examining the expressions of 5-HT_3 and 5-HT_4mRNA and proteins by RT-PCR and Western blotting respectively. Results ① The levels of serum amylase and 5-HT in AP group and treatment group were significantly higher than those in sham operation group (P<0. 01), but they were lower in treatment group than in AP group at each time points (P<0. 05). The level of 5-HT was increased in the initial stage and then decreased gradually both in AP group and treatment group. ③ The expressions of 5-HT_3 and 5-HT_4 mRNA and proteins were significantly decreased in the jejunum, terminal ileum and sigmoid colon in AP group compared with sham operation group (P<0. 01). Whereas the expressions of 5-HT_3 mRNA and protein,but not 5-HT_4, were increased in the treatment group in comparison with AP group (P<0.05). Conclusions The level of 5-HT is significantly increased in acute pancreatitis, but its receptors (5-HT_3 and 5-HT_4) are decreased, which may induce enteric functional disturbance. The Da-Cheng-Qi decoction may improve enteric dynamic failure by increasing the expression of 5-HT_4 and may be a choice for treatment of acute pancreatitis with enteric dynamic failure
