Objective To investigate the role and expression of serum substance P (SP) in the patients with breast cancer.Methods The quantity of serum SP by using ELISA in 21 patients with breast cancer (breast cancer group) and 10 healthy women (control group) were detected,the data were analyzed according to AJCC guide line.Results The positive rate of serum SP in breast cancer group was significantly higher than that in control group [57.1％ (12/21) vs.0] (P ＜ 0.01).The level of serum SP in breast cancer group was significantly higher than that in control group [(240.14 ± 435.04) ng/L vs.(16.80 ± 11.74) ng/L](t =2.9852,P ＜ 0.01).There was no relationship between serum SP and estrogen receptor in the patients with breast cancer (t =0.1856,P ＞ 0.05).The level of serum SP showed significantly difference according to AJCC stages respectively (F =3.24,P ＜ 0.05).Conclusion The level of serum SP in the patients with breast cancer increase and may play a role in the progress of breast cancer.

Hepatocellular carcinoma (HCC) is the most common malignant cancer in China. The size of HCC can be categorized into 4 grades: (1) micro-HCC, the diameter of the HCC is ≤2 cm; (2) small HCC, the diameter of the HCC is between 2 and 5 cm; (3) large HCC, the diameter of the HCC is between 5 and 10 cm; (4) giant HCC, the diameter of the HCC is > 10 era. The new classification helps to choose the appropriate methods and to analyze the curative effect for various kinds of HCC respectively. The resection of large and giant HCC is safe and feasible. During the past 20 years, we have modified and innovated some techniques of HCC surgery, including hepatectomy without dissecting the hepatic hilus, increasing the safety time limit of portal pedicle occlusion from 15-20 minutes to 20-60 minutes, in situ bepatectomy with occlusion of hepatoduodenal ligament and infrahepatic vena cava, and double hanging maneuver techniques. The techniques mentioned above improved the bleeding control of hepatectomy, and enhanced the long-term survival rate of HCC patients.

The robotic surgical system can provide a stable, clear and magnified three-dimensional view, filter the surgeon's hand tremor, and hold robotic arms with multiple degrees of freedom to ensure flexible and stable operations, which overcomes the shortcomings of traditional laparoscopy. Although the robotic surgical system has been widely used in surgical fields such as urology, obstetrics and gynecology, its role in hepatic surgery has not been fully recognized. In this article, based on the relevant literatures and their own experience, the authors briefly discuss the indications of the application of robotic surgical system in liver surgery, safety and efficacy of robotic liver resection, learning curve of robotic hepatectomy, difficult robotic hepatectomy, the cost of robotic liver resection and other issues.

Objective　To improve the treatment effect of primary hepatic cancer (PHC). Methods　Analysis of the influential factors on treatment effect of PHC in China, and propose the countermeasure. Results and Conclusions　The main factors influencing the treatment effect of PHC in China are the followings: (1) Most patients with PHC of subclinical type failed to be diagnosed and treatment in time. (2) As a wrong idea PHC has been considered an “uncurable disease", so the treatment strategy is nagative. (3) Unsuitable choice of treatment resulted in some PHC unable to be resected. (4) Intraoperative massive bleeding due to unskill-operative techniques, increase the postoperative morbidity and mortality. (5) The manner of treatment is not positive for PHC patients with portal cancer thrombosis, bile duct cancer hteombosis and portal hyperlension. (6) Combined therapy can not be used or unsuitably used. The following things should be done in order to improve the treatment effect of PHC: (1) Strengthening improving the health-protective consciousness of people and regular examinaton of “high risk" population. (2) Renewing the professional knowledge in time to improve the level of diagnosis, treatment and operative techniques of medical personnel. (3) strengthening the basic medical research to make a break through in PHC treatment.

Objective To observe the effects of octreotide combined with enzyme supplementation in treatment of pain in chronic pancreatitis. Methods Fifty-six patients were divided into two groups. Thirty-six patients in the treatment group were treated with octreotide combined with enzyme supplementation,and twenty patients in the control group were treated with enzyme supplementation alone. The pain relief rate,analgesic requirement per day and average days in hospital were analyzed between the two groups. Results Compared with the control group,the treatment group presented better improvement of abdominal pain(P〈0. 05),less requirement of analgesics(P〈0. 05),and shorter duration in hospital(P〈0. 05). Conclusion Octreotide combined with enzyme supplementation is effective in alleviating pain and improving quality of life in patients with chronic pancreatitis.

Intravascular large B cell lymphoma is a rare subtype of diffuse large B cell lymphoma. Abnormal proliferation of intravascular lymphoma cells is its pathological feature with aggressive clinical behavior such as easy invasive feature, rapid disease progression, poor prognosis and low survival rate. We review the progress in recent research on classification, diagnosis, treatment and prognosis of intravascular large B cell lymphoma.

ObjectiveTo study the relationship among serum levels of interleukin-12 (IL-12), interleukin-2 (IL-2), and soluble interleukin-2 receptor (sIL-2R) in patients with hepatocellular carcinoma (HCC).Methods60 patients were randomized into two groups, group A (n=30) received IL-2 (1 MIU?day -1 for seven days), group B (n=30) served as control. Venous blood levels of IL-12?IL-2 and sIL-2R in all patients were measured by enzyme-linked immunosorbent assay (ELISA) before and after the IL-2 administration. Results There was positive correlation between serum levels of IL-2 and IL-12, negative correlation between serum levels of IL-2 and sIL-2R and no correlation between that of IL-12 and sIL-2R. Mean serum levels of IL-12,IL-2 and sIL-2R significantly (P
