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.

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.

Layered anatomy is a both ancient and novel conception, which is derived from topographic anatomy.Topographic anatomy and phylembryogenesis are basic academic knowledges of layered anatomy.With the development of laparoscopic surgery and robotic surgery, less bleeding, more meticulous dissection, faster postoperative recovery and lower recurrence rate are required in surgical operation, because of which layered anatomy is mentioned and valued again.Organs in abdominal cavity are composed of different layered tissues,between them are loose connective tissues which are poor in vessels.Layered anatomy in surgical operation can avoid the en bloc dissection of organs, which not only reach total lesion dissection, but also avoid hurting surrounded normal tissues, showing the best surgical results.

Mental Health Law has specify the mental disorder patients’ informed consent right,but in practice, the problems,the mental health status of patients, namely the families’ right of subrogation exercise,“loss of self-control or deny having mental disorder”, have prevented the exercising of informed consent right. Therefore,it is necessary to effectively solve this plight of rebuilding a harmonious relationship between doctors and patients,estab-lishing mentally disordered patients’ right to advance directives, especially choosing the instrument of assessing the individual’ s capacity to consent.

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

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.

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.

A 4-year-old girl presented with generalized papules, erythema, desquamation, subcuta-neousnodules around large joints, as well as a 3-year-history of progressive eye damage. Three months after her birth, papules developed on the lower limbs, and gradually spread to involve the whole body. Eye damage appeared after a high fever and she was diagnosed with keratoleukoma, old iritis, and posterior synechia. Physical examination revealed sharply demarcated corneal opacity, shallow anterior chamber, obscure irides, and posterior synechia; pupils were not round. No superficial lymphadenectasis was observed. Dermatological examination showed ichthyosis-like coarse skin with generalized papules, erythema and desquamation, increased wrinkles and absence of sweat. Skin temperature was higher than normal. There were soft, irregu-larly sized, non-tender, movable subcutaneous masses at the wrist, ankle and knee joints without inflamma-tion or warmth. Type-B uitrasonography of both eyes disclosed vitreous opacification, posterior detachment of vitreous, extravasation at the posterior vitreous membrane, and decreased intraocular pressure. Histopathology of lesions on the back, waist, and back of hands as well as subcutaneous nodules on the wrists showed epidermal acanthosis and infiltration with a large number of histiocytes, foam cells and multi-nucleated giant cells in the dermis. No abnormal findings were observed from other examinations. This case was diagnosed as Blau syndrome, which is an autosomal dominant inherited disease; currently, there is no effective therapy for it.
