Funcoidan (FCD) is a polysaccharide extracted from Laminaria japonica Aresh. When we injected FCD into mice subcutaneously for 9 days in our experiments, splenocyte proliferation induced by mitogen (Con A, PHA, LPS), IL - 1 production of peritoneal M?induced by Lps and IL - 2 production of splenocyte induced by Con A were promoted and the primary antibody response to SRBC of murine splenocyte was also promoted. FCD could directly stimulated murine splenocyte to produce IFN - 7. FCD, in vitro or in vivo ,could enhance NK activity.

OBJECTIVETo compare the differences of clinical effects on primary hypertension between acupuncture combined with auricular point sticking and western medicine.

METHODSNinety patients with primary hypertension were randomly divided into a medication group and a combination group, 45 cases in each group. In the medication group, captopril tablets were treated with oral administration, 12.5 mg each time, twice a day; in the combination group, acupuncture and auricular point sticking were used, and acupuncture was applied at Renying (ST 9), Fengchi (GB 20) and Baihui (GV 20), while auricular point sticking was adopted at Shenmen (TF4), Xin (CO15), Jiangyagou and Jiaogan (AH6a), once a day for continuous 4 weeks. After treatment, the changes of 24 h ambulatory blood pressure, angiotensin II (Ang II) level, creatinine level and syndrome scores were observed and the clinical efficacy was assessed in the two groups.

RESULTSAfter 4 weeks' treatment, the 24 h ambulatory blood pressure was both improved compared with that before treatment in the two groups (P<0.01, P<0.05). The reducing of 24 h ambulatory blood pressure in the combination group was superior to that in the medication group (P<0.05). There were reducing tendencies about coefficients of variation (CVs) of the two groups, and in the combination group, the CVs of 24 h ambulatory blood pressure and systolic pressure acquired more obvious reducing range compared with the medication group (both P<0.05). Serum Ang II level and plasma creatinine level of the patients in the two groups after treatment were both decreased (both P<0.05) and the reducing of Ang II level and creatinine level of the combination group was more obvious than that of the medication group (both P<0.05). The syndrome scores of the two groups after treatment were both remarkably decreased (both P<0.05), and the reducing of the syndrome scores of the combination group was more marked than that of the medication group (P<0.05). The total effective rate of the combination group was 95.6% (43/45), which was superior to 71.1% (32/45) of the medication group (P<0.05).

CONCLUSIONAcupuncture combined with auricular point sticking for primary hypertension has reliable effect. It is better than captopril for the improvement of 24 h ambulatory blood pressure, AngII level and creatinine level, and can improve dizzy, palpitation and other clinical symptoms.

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.

Objective To analyze the data of concentric (c) and eccentric (e) peak torque of hamstring (H) and quadricep (Q) in differ-ent gender and angle after 4-week concentric and eccentric isokinetic exercise training on knee, in order to provide suggestions for the knee extensor and flexor in rehabilitation exercise prescription. Methods 28 healthy college students from May to June 2014 in our college partic-ipated in maximum concentric (n=14) or eccentric (n=14) resistance training of the right knee extensors and flexors 3 times per week for 4 weeks. The concentric strength was measured with BIODEX isokinetic dynamometer assessment system 4 at 30 °/s, 60 °/s, 90 °/s, and ec-centric strength was measured at 60 °/s, 120 °/s, 180 °/s. PT, H/Q (He/Qc, Hc/Qc) ratio and H/H (He/Hc) or Q/Q(Qe/Qc) ratio were ana-lyzed. Results Concentric isokinetic training could improve the Hc and He at 60 °/s and 90 °/s (P<0.05), and the Qe and Qc increased at 30 °/s, 60 °/s, 90 °/s respectively (P<0.01). There was no significant improvement after eccentric training (P>0.05). After concentric isokinet-ic training, the He/Qc ratio decreased at 90 °/s (P<0.05), the Hc/Qc ratio decreased at 30 °/s (P<0.05). However, there was no difference in He/Qc and Hc/Qc after eccentric contraction (P>0.05). The Qc/Qe ratio increased at 60 °/s and 90 °/s (P<0.05), and the Hc/He ratio de-creased at 90 °/s (P<0.05) after concentric training. There was no difference in Hc/He and Qc/Qe after eccentric contraction (P>0.05). There were significant differences in Hc, He, Qc, Qe and He/Qc ratio between different genders (P<0.05). Conclusion Concentric training and ec-centric training have different influences on the muscle strength after 4 weeks training. Eccentric training only can reduce the knee stability. Hc/He ratio and Qc/Qe ratio can be used to evaluate the knee muscle function. Gender should be considered into training.

Objective To study the morphological characteristics of tumor microvasculature in primary hepatic cell carcinoma (HCC). Methods From Jan. 1998 to Feb. 2002, 32 cases, consisting of 26 male and 6 female, with age ranging from 28 to 76 years [mean (50.56?10.52) years], underwent preoperative digital subtraction angiography (DSA) without theraputic embolization in General Hospital of PLA and 307 hospital of PLA. The diameters of the tumors measured 2～23 (8.05?6.17) cm. The tumor microvessel density (MVD), type and diameter of the tumor microvessels, width of tumor trabeculae, and the size of the malignancy were measured and statistically analyzed. The outcome of the each patient was also statistically analysed. Results The size of tumor tended to be positivly correlated with the pattern of microvasculature of the tumor. The size of the tumor was negatively correlated with MVD, white the tumor size and the diameter of tumor related vessels were positively correlated with the diarneter of tumor trabeculae. Hoverer, the size of the tumor was not correlated with the diameter of vascular trabeculae. Conclusions The density, configuration and the distribution of tumor microvessels were not even in HCC. The features of tumor microvasculature were distinctive at different phases of tumor growth, having definite rules in the development.
