AIM: To evaluate the antioxidant properties in vitro of Longxuejie Capsule (Sanguis draconis) (LC). METHODS: The antioxidant activities of Longxuejie Capsules were investigated by employing several external assay systems, including 1,1-diphenyl-2-picrylhydrazyl (DPPH?)/peroxide anion/hydroxyl radical-scavenging, reducing power assay system, peroxidation of polyunsaturated fatty acid from yolk lipoprotein induced by Fe~ 2+ method, and ?-carotene/linoleic acid assay system. RESULTS: The LC showed scavenging activity against free radicals, such as DPPH?, peroxide anion and hydroxyl radicals. LC also exhibited effective reducing power and powerful inhibitory effects on peroxidation of polyunsaturated fatty acid from yolk lipoprotein induced by Fe~ 2+ . Furthermore, LC showed markedly inhibitory effect on ?-carotene/linoleic acid assay system. CONCLUSION: Longxuejie Capsule has obvious antioxidant activities in vitro

The synergistic cytotoxicity of rhTNF-? or/and six chemotherapeutic agents namely ADM, MMC, DDP, VP-16, GBP and IFO, against two human hepatic carcinoma cell lines, SMMC-7721 and BEL-7402, was examined by MTT assay. The results showed that the cytotoxic effects of six chemotherapeutic agents with rhTNF-? against two cell lines were significant. Examined cytotoxicity of rhTNF-? combined with chemotherapeutic agents, we found that rhTNF-? singnificantly enhanced cytotoxic efficacy of ADM, DDP, VP-16. The study suggested that rhTNF-? with some chemotherapeutic agents had synergistic effects. This and other preclinical studies with rhTNF-? will form the basis of clinical treatments for hepatic carcinoma patient.

BACKGROUND:Deep venous thrombosis has already been recognized as an important serious postoperative complication because it can cause fatal pulmonary embolism and long-term deep venous dysfunction. With the constant development of artificial joint operation and the popularization of such surgery, much attention has been paid to the formation of deep venous thrombosis following artificial joint replacement.OBJECTIVE: To observe the anatomical property of acetabular surrounding arteries and veins, as well as their injury during total hip replacement,so as to explore the cause of deep venous thrombosis in lower limbs following artificial total hip replacement.DESIGN: Single sample observation and before-after self-control.SETTING: Gross anatomy was carried out in the anatomical laboratory of the Medical School of Huzhou Teachers' College; total hip replacement was carried out in the Orthopedic Department, Xinhua Hospital of Zhejiang Traditional Chinese Medicine College.PARTICIPANTS: Pelvic samples were collected from 60 normal adult corpuses (30 from men and 30 from women); meanwhile, 30 patients (18 males and 12 females) received total hip replacement in the Orthopedic Department of Xinhua Hospital, Zhejiang Traditional Chinese Medicine College, between March 2002 and August 2003.METHODS: Gross anatomy was carried out at the anatomical laboratory in the Medical School of Huzhou Teachers' College between March and May 2003. The running course of bilateral external iliac artery and vein, as well as the relationship between the branches of femoral artery and vein and acetabulum were observed on 60 pelvic samples. In order to make the observation easier, 12 o'clock division mode chart of acetabulum was established, that is, a line drawn from anterior superior iliac spine toanterior inferior iliac spine, with the crossing point of its extension line and acetabular edge taken as 12 o'clock, therefore the other points should be arranged clockwise. Totally 30 patients received artificial total hip replacement by acetabular lateral-posterior approach. One week later, bilateral deep venous radiography was performed to observe the state of deep venous thrombosis in lower limbs.MAIN OUTCOME MEASURES: ① The anatomical relationship between the branches of external iliac artery and vein, femoral artery and vein and acetabulum. ② The formation rate of deep venous thrombosis in lower limbs after total hip replacement. ③ Adverse events and side effects.RESULTS: Totally 60 adult normal pelvic samples and other 30 pelvic samples of patients who received total hip replacement remained in the results analysis. ① Anatomical observation of external iliac artery and vein,as well as femoral artery and vein: the branches of femoral artery and vein: Medial and lateral circumflex femoral arteries were found running across acetabulum and entering acetabulum; the safe position for the retractor was from 12 o'clock to 3 o'clock and from 5 o'clock to 9 o'clock. However, 9o'clock to12 o'clock and 3 o'clock to 5 o'clock were taken as fragile regions. ② The incidence of deep venous thrombosis following total hip replacement: Bilateral deep venous radiography was carried out after operation and revealed that 11 patients developed deep venous thrombosis with the incidence of 37%. ③ Adverse events and side effects: Postoperative bleeding of over 1 000 mL occurred in 3 cases. In order to fully expose operative field, the retractor should be used to hold off muscles and other tissues, which contributed to long-term vascular compression and blood flow retardation.CONCLUSION: Artificial total hip replacement is liable to injure the internal wall of acetabular vessels, thereby leading to blood flow retardation and platelet aggregation, and ultimately thrombosis. In addition, the massive bleeding during operation will increase blood mucosity, which also increases the risk for thrombosis. From the mode chart of fragile regions and safe regions, we can deduce that deep venous thrombosis in lower limbs can be reduced.

BACKGROUND: At present, the artificial total hip replacement(THR) is the first choice of the hip joint disease for the old, and the choiceness rate is 84% according to the Harri' s grade, and the therapeutic effect is content. The occurrence rate of the sciatic nerve injury in the THR is reported to be 0.46% in and 0. 08%-9.7% abroad.OBJECTIVE: To study the influencing factors of the sciatic nerve injury in the THR through the anatomical location analysis.DESIGN: Single sample study based on the human anatomical samples.SETTING: Human Anatomy Laboratory in the Medical Department of the Huzhou Normal University.PARTICIPANTS: The study was completed in the Human Anatomy Laboratory in the Medical Department of the Huzhou Normal University from March to May in 2003. There were 56 pelvis samples of the normal human adult cadaver, 27 males and 29 females.METHODS: The origins and the pathways of the sciatic nerves and the relation of the sciatic nerve and the acetabulum were analyzed, and the sciatic nerve injury induced by the clasp and the screw fixation in the THR was measured and analyzed.MAIN OUTCOME MEASURES: The location relation of the sciatic nerve and the acetabulum.RESULTS: The distance between the sciatic nerve and the bottom of the acetabulum was(6.00 ±0. 85) mm on the left and(6.00 ±0. 71) mm on the right. The distance between the sciatic nerve and the edge of the acetabulum was(13.00 ±0. 75) mm on the left and(14.00 ±0.06) mm on the right. The SN circumference on the edge of the acetabulum was(32.00 ± 0. 28) mm on the left and(31.00 ± 0.68) mm on the right. The distance between the bottom of the acetabulum and the greater sciatic foramen was(29.00 ±0. 36)mm on the left and(29.00 ±0.24) mm on the right.CONCLUSION: It is confirmed that the clasp and the screw fixation can be done on the safe region at the 1-3 o' clock and the 5-6 o' clock. The obsolete fracture and dislocation of the acetabulum, the unsuitable clasp location and the unsuitable location of screw fixation may induce the iatrogenic sciatic nerve injury.
