OBJECTIVETo explore the therapeutic effect of acupuncture for hypertensive cerebral hemorrhage at the early stage.

METHODSFifty-four cases of small-amount cerebral hemorrhage were randomized into an acupuncture group and a conventional treatment group, 27 cases in each one. In the conventional treatment group, special care, oxygen therapy, nerve nutrition and symptomatic support were applied. In necessary, dehydrant and hypotensive drugs were prescribed for antihypertension, or surgery was given. In the acupuncture group, on the basis of the treatment as the control group, acupuncture was applied at Quchi (LI 11), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3). Acupuncture was given at the admission, 4 h, 6 h and 12 h after disease onset respectively. Blood pressure was monitored in the whole procedure. 6 h and 24 h after disease onset, the cranial CT was re-examined. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), hematoma volume and neurological deficit score were compared at different time points between the two groups.

RESULTS(1) Blood pressure: from the admission to 12 h after disease onset, SBP, DBP and MAP were increased apparently in the conventional treatment group and increased slightly in the acupuncture group. The differences in SBP [(164.3 +/- 21.6) mmHg vs (158.6 +/- 21.5) mmHg] and MAP [(113.4 +/- 4.9) mmHg vs (106.7 +/- 6.1) mmHg] were significant between the two groups (both P < 0.05). From 12 h to 24 h after disease onset, compared with the conventional treatment group, SBP and MAP were decreased apparently in the acupuncture group [(147.3 +/- 21.6) mmHg vs (158.4 +/- 23.5) mmHg, (97.2 +/- 5.3) mmHg vs (106.6 +/- 5.1) mmHg, both P < 0.05)]. (2) Hematoma volume: from the admission to 6 h after disease onset, the volume was increased by (4.15 +/- 0.73) mL in the convertional treatment group and (2.67 +/- 0.33) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). From the admission to 24 h after disease onset, it was increased by (5.57 +/- 1.26) mL in the convertional treatment group and (3.14 +/- 1.18) mL in the acupuncture group, indicating the significant difference in comparison (P < 0.05). (3) Neurological deficit score: the score was increasing gradually in first 3 days after disease onset in the two groups. The score (38.39 +/- 6.84) in the acupuncture group on the first day was different significantly as compared with that (42.37 +/- 7.46) in the conventional treatment group (P < 0.05). On the 10th days, the score (24.68 +/- 5.42) in the acupuncture group was different significantly from that (29.74 +/- 7.36) in the convertional treatment group (P < 0.05).

CONCLUSIONThere is no peak of blood pressure rising, and the continuous hemorrhagic volume is less in 24 h and neurological deficit score is improved in the acupuncture group. Acupuncture brings the positive significance in the treatment of cerebral hemorrhage at the early stage.

Functional training is put a very high position in the treatment of fractures by Western Medicine and Traditional Chinese Medicine. The influences of functional training during fracture healing are very important. Functional training will begin after reduction and fixation and it represents the principle of the combination of functional training and fixation in the fracture treatment by TCM. Functional training makes kinds of favourable stress, which can accelerate the healing of fracture, but the incorrect functional training makes shear strength or torsion and so on, which may make interfere fracture healing. So, the biomechanical studies on functional training of the fracture are becoming a focus of fracture treatment.

Aim To study inhibitory effect of 5-fluorouracil encapsulated by galactosylceramide liposomes (5-Fu-GCL)on 5-Fu-resistent HepG_2 cells and its mechanisms. Methods Inhibitory effect of 5-Fu-GCL on established model of 5-Fu-resistant HepG_2 cells was assessed with MTT assay in vitro. The concentration-time course of 5-Fu-GCL in intracellular fluid was detected with high performance liquid chromatography (HPLC). Thymidylic acid synthase (TS) expression was observed with immunohistochemical method,and NO content was determined with chemical method. Results Obvious inhibitory effects of 5-Fu-GCL (75,150,300,600,1200?mol?L-1) on 5-Fu-resistant HepG_2 cells were observed with IC_ 50 of 158.6 ?mol?L-1,far lower than that of free 5-Fu (400.9 ?mol?L-1). 5-Fu-GCL (300 ?mol?L-1) inhibited 5-Fu-resistant HepG_2 cells in a time-dependent manner,and the inhibitory effect of 5-Fu-GCL was stronger than that of free 5-Fu during 12～48 h. Compared with free 5-Fu,5-Fu-GCL (300 ?mol?L-1) increased the content of intracellular fluid in 5-Fu-resistant HepG_2 cells. 5-Fu-GCL(62.5,300,1200 ?mol?L-1) not only inhibited the expression of TS,but also increased the production of NO in 5-Fu-resistant HepG_2 cells,and these effects of 5-Fu-GCL(300,1200 ?mol?L-1) were stronger than those of free 5-Fu. Conclusion 5-Fu-GCL has inhibitory effect on 5-Fu-resistant HepG_2 cells. The effect may be related to the increased concentration of 5-Fu-GCL in intracellular fluid,inhibited expression of TS and increased production of NO.

Activation of acid-sensing ion channels (ASICs) plays an important role in neuroinflammation.Macrophage recruitment to the sites of inflammation is an essential step in host defense.ASIC 1 and ASIC3 have been reported to mediate the endocytosis and maturation of bone marrow derived macrophages.However,the expression and inflammation-related functions of ASICs in RAW 264.7 cells,another common macrophage,are still elusive.In the present study,we first demonstrated the presence of ASIC 1,ASIC2a and ASIC3 in RAW 264.7 macrophage cell line by using reverse transcriptase polymerase chain reaction (RT-PCR),Western blotting and immunofluorescence experiments.The non-specific ASICs inhibitor amiloride and specific homomeric ASIC 1 a blocker PcTx 1 reduced the production of iNOS and COX-2 by LPS-induced activating RAW 264.7 cells.Furthermore,not only amiloride but also PcTx 1 inhibited the migration and LPS-induced apoptosis of RAW 264.7 cells.Taken together,our findings suggest that ASICs promote the inflammatory response and apoptosis of RAW 264.7 cells,and ASICs may serve as a potential novel target for immunological disease therapy.

OBJECTIVETo investigate the relation between lipoprotein (a) (LP(a)) and cerebral infarction in young adults.

METHODSSerum LP(a) of 90 young adults (age below 45 years) with cerebral infarction was measured. Serum lipids include triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol, low density lipoprotein cholesterol, apolipoprotein A-I (ApoA-I) and apolipoprotein B (ApoB) were also measured. Other possible risk factors such as hypertension, smoking, drinking and family stroke history were reviewed.

RESULTSThere was no significant difference of serum LP(a) value between stroke patients and controls. TG (P < 0.01) and ApoB (P < 0.01) values in patients with cerebral infarction were significant higher than those in controls. Lipoprotein (a) was correlated with total cholesterol and low density lipoprotein cholesterol, with the values of correlation coefficient (r) 0.28 and 0.23 (both P < 0.01). After adjustment for age, sex, hypertension, smoking, drinking alcohol, family stroke history and other serum lipids, the odd radio for LP(a) and cerebral infarction was 0.74 (95% CI: 0.27 - 1.98). The odd radio for elevated TG was 3.57 (95% CI: 1.34 - 9.49); The odd ratios for hypertension, heart diseases and smoking as risk factors for cerebral infarction in young patients showed as: hypertension OR = 8.18, 95% CI: 2.54 - 26.33; heart diseases: OR = 8.51, 95% CI: 2.27 - 31.85; smoking: OR = 3.21, 95% CI: 1.27 - 8.13.

CONCLUSIONLP(a) might not be a risk factor for cerebral infarction in young patients while elevated triglyceride, hypertension, heart diseases and smoking were important risk factors in young adults with cerebral infarction.

Hemopexin (HPX) is a plasma protein with the strongest binding capacity to heme and widely involved in modulation of a variety of physiological and pathological processes. The main physiological function of HPX is to bind and transport free toxic heme. Recent studies indicate that HPX also plays roles of anti-oxidant, anti-apoptosis, immune regulation and organic protection. In addition, HPX participates in regulation of cell differentiation and extracellular matrix reconstruction. In recent years, a great deal of progress has been made in studies of the mechanisms of HPX protective effects and on possible clinical application. In the past few years, especially, a number of proteomic studies have demonstrated that HPX could be served as positive molecular biomarkers for cancers of lung, liver, kidney, colon, and uterine myoma as well as osteoarthritis. In this review, recent progress in the biochemical characteristics and function of HPX and its possible clinical applications are summarized.

OBJECTIVETo observe the effect of Panax notoginseng (PN) on pathological features in chronic subdural hematoma (CSDH) rabbits and its mechanisms.

METHODSA stable pathological animal model similar to CSDH in humans could be established using subdural injections of small number of blood through a subdural pre-catheter in rabbits. After successful modeling, 18 rabbits were randomly divided into the model group, the low dose PN group (0.125 g/kg), and the high dose PN group (0.250 g/kg), 6 in each group. Normal saline was given to rabbits in the model group, while PN power was given to those in the PN groups by gastrogavage for 6 successive days. Pathologic features of the hematoma outer membrane were observed by HE staining. The activity of SOD and the content of MDA in the hematoma outer membrane were examined by the colorimetric method. Expressions of CD31, CD34, and VEGF in the hematoma outer membrane were observed by immunohistochemical assay. Expressions of VEGF in the peripheral blood and the subdural hematoma were detected by enzyme-linked immunosorbent assay (ELISA). Expressions of VEGFR-1 and VEGFR-2 in the hematoma outer membrane were detected by Western blot.

RESULTSCompared with the model group, the inflammatory reaction was comparatively lessen and the proliferation of the fibrous tissue was relatively mature in the low and high dose PN groups. The activity of SOD increased (P < 0.05); expressions of CD31 and CD34 were reduced (P < 0.01); VEGF expression in the residual hematoma fluid decreased (P < 0.05) in the high dose PN group. Expressions of VEGF and VEGFR-2 were all reduced in the high and low dose PN groups (P < 0. 05, P < 0.01). Compared with the low dose PN group, expressions of CD31 and CD34 were reduced (P < 0.01), and the VEGFR-2 expression was also reduced (P < 0.05) in the high dose PN group.

CONCLUSIONSPN could promote the fibrous repairing of subdural hematoma in CSDH rabbits. It also lessened inflammation and oxidative injury of the hematoma outer membrane and reduced expressions of VEGF. The pathological angiogenesis could be reduced through influencing VEGFR-2 receptor pathways, which might be an important mechanism.

OBJECTIVETo study the expression of gastric and intestinal phenotypic markers in gastric signet-ring cell (SRC) carcinoma and the relationship with the clinicopathologic parameters and prognosis.

METHODSImmunohistochemical study was carried out in 91 cases of early-stage SRC carcinoma using MUC1, MUC5AC and MUC6 antibodies as the gastric phenotypic markers and MUC2 and CDX2 antibodies as the intestinal phenotypic markers. According to the expression of phenotypic markers, the tumors were classified into three different subgroups: gastric, intestinal and mixed. The findings were analyzed together with various clinical parameters and follow-up data.

RESULTSAmongst the 91 cases studied, 53 cases (58.2%) belonged to gastric type, 22 cases (24.2%) mixed type and 16 cases (17.6%) intestinal type. The positive rates of MUC2 and CDX2 in early submucosal carcinoma were significantly higher than those in mucosal carcinoma (P < 0.01). On the other hand, the rates of MUC5AC and MUC6 expression in early submucosal carcinoma were significantly lower than those in mucosal carcinoma (P < 0.01 and P < 0.05). The rates of MUC2 and CDX2 expression in cases with lymph node metastasis and vascular invasion were significantly higher than those in cases without nodal or vascular involvement (P < 0.05). The expression of CDX2 was also significantly higher in cases with larger tumor size (P < 0.05). Cases with intestinal phenotype more likely had invasion deeper than mucosal layer and carried higher chance of lymph node metastasis (P = 0.000 and P = 0.003). Intestinal and mixed types correlated with shortened five-year survival.

CONCLUSIONSThe intestinal type of SRC carcinoma is associated with poorer biologic behavior and prognosis, as compared with that of the gastric type. Classification on the basis of immunophenotypic markers may be useful in predicting prognosis and guiding treatment for patients with gastric SRC carcinoma.
