Objective To investigate the expressions of complements 3 (C3), 4B1 (C4B1) and apolipoprotein E (ApoE) in pancreatic cancer and relations with TNM staging and lymph node metastasis of pancreatic cancer. Methods Thirty-eight pancreatic cancer biopsy specimens, 20 fresh pancreatic cancer specimens and 20 adjacent normal tissues of pancreatic cancer were collected. The expressions of C3, C4B1, ApoE in pancreatic cancers and normal pancreatic tissues were detected by immunohistochemistry and Western-Blot, the positive expression rates of C3, C4B1, ApoE and the differences in gray scale were also observed. Their association with pancreatic cancer TNM staging and lymph node metastasis were analyzed by SPSS 13.0. Results The expression rates of C3, C4B1, ApoE in pancreatic cancer were 73.68% (28/38), 86.84%(29/38) and 76.31% (33/38) respectively, higher than those in normal pancreatic tissues which were 42.11% (16/38), 26.32% (10/38) and 42.11% (16/38) accordingly, the differences were statistically significant (χ2 was 7.77, 19.01, 16.6, and P value were 0.01, 0.00, 0.00 respectively). The gray scale of C3, C4B1 and ApoE in pancreatic cancer were 1.63±0.28,1.25±0.18 and 2.57±0.22 respectively, higher than those in normal pancreatic tissue (0.88±0.19,0.65±0.13,1.28±0.24 respectively), the differences were statistically significant (t value were 9.93,11.81,17.71 and all P value were 0.00, respectively). There was no association between C3 and TNM staging or lymphatic metastasis of pancreatic cancer. C4B1 and ApoE were closely related with TNM stage and lymph node metastases. The expressions of C4B1 and ApoE in stage Ⅱ to Ⅳ pancreatic cancer or with lymphatic metastasis were significantly higher than those in stage Ⅰpancreatic cancer and those without lymph node metastasis. Conclusion C3, C4B1 and ApoE were all highly expressed in pancreatic cancer. C3 was only involved in early event in pancreatic cancer, not related with development of pancreatic cancer. C4B1 and ApoE were involved in tumor growth and metastasis.

Objective To investigate the expression of apolipoprotein E (ApoE) and complement C4b1 in pancreatic carcinoma and study its significance. Methods Immunohistochemistry was used to detect the expression of ApoE and C4b1 protein in 38 cases of pancreatic carcinoma tissues and adjacent normal pancreatic tissues, and RT-PCR was used to detect the expression of ApoE and C4b1 mRNA in 20 cases of pancreatic carcinoma tissues and adjancent normal pancreatic tissues. The relevance of ApoE and C4b1 expressions to the biological features of pancreatic carcinoma were analyzed. Results The positive rates of ApoE and C4b1 expressions are 86.8% (33/38) and 76.3% (29/38) in pancreatic carcinoma, respectively,which were significantly higher than those in normal pancreatic tissues [42.1% (16/38) and 26.3% ( 10/38 ),P ＜ 0.01]. The positive rates of ApoE and C4b1 expressions [78.3% ( 18/23 ) and 73.9% ( 17/23 )] in patients with metastasis were significantly higher than in those without metastasis [(33.3% (5/15) and 40.0%(6/15), P ＜ 0.05). Significantly higher expressions of ApoE and C4b1 mRNA were noted in pancreatic carcinoma(4.83 ± 0.65 and 7.94 ± 0. 95 ) than those in the normal pancreatic tissue ( 1.78 ± 0.74and 1.22 ±0.57, P ＜ 0.01 ), and patients with metastasis showed significantly higher expression of ApoE and C4b1 mRNA (5.05 ±0.71 and 8.24 ± 1.07) than those without metastasis (4.42 ±0.25 and 7.39 ±0.15,P ＜ 0.05). Conclusions ApoE and C4b1 were highly expressed in pancreatic cancer, and may be closely related with lymph node metastasis.

Objective　To study the effects of sFas in hepatocellular cancer (HCC) and chronic hepatitis (CH). Methods　The serum sFas was detected in 18 patients with HCC, 12 patients with CH and 6 cases of normal control by ELISA. Results　The serum sFas in HCC was obviously increased and had significant difference with the patients of CH and normal control (P<0.01). The serum sFas had positive correlation with the serum TBIL(P<0.01), but negative correlation with the ALB, PTA and the ratio of ALT/AST(P<0.01).Conclusions　sFas may resist the occurrence of HCC apoptosis. In CH, sFas has correlation with the severity of CH. The role of sFas in viral hepatitis is uncertain.

Objective To investigate the association of C3 and ApoE expressions with lymph node metastasis and clinical pathological stage of human pancreatic cancer. Methods Immunohistochemistry was used to detect the expression of C3 and ApoE in pancreatic cancer's tissues and normal pancreatic tissues,and the relevance of C3 and APoE expressions to the metastasis of pancreatic cancer was analyzed. Results The positive rates of C3 and ApoE expressions were 73.68% and 86.84% in pancreatic cancer,significantly higher than those in normal pancreas tissues (42.11% and 42.11%, P＜0.01 ). The positive rate of C3 expressions in pancreatic cancer of lymph node metastasis was 56.52%, in those without lymph node metastasis was 46.67% (P=0.741). The positive rate of C3 expressions in pancreatic cancer of stage Ⅰ was 57.14%, in those of stage Ⅱ - Ⅳ was 77.42% (P=0.194). The positive rate of ApoE expressions in pancreatic cancer of lymph node metastasis was 78.26%, significantly higher than those without lymph node metastasis (33. 33%, P＜0.01). The positive rate of ApoE expressions in pancreatic cancer of stage Ⅰ was 57. 14%, significantly lower than those of stage Ⅱ - Ⅳ (93.55%, P ＜0.05 ). Conclusions C3 and ApoEare all overexpressed in pancreatic cancer. C3 is not related with tumor's lymph node metastasis and clinical stages, may be marker for early diagnosis of pancreatic cancer. ApoE is closely related with tumor' s development, may reflect the biological behavior of pancreatic cancer.

Objective To observe the change of cerebral oxygen metablism and the level of blood lactate in early stage of sepsis in rats.Method Sixty-four SD rats were randomly(random number)divided into septic group and control group.The sepsis model of rat was made by lipopolysaccharide (LPS,10 mg/kg)injected intra-abdominally,and rats of control group were treated with the same amount of physiological saline instead.And each group was further divided into 4 sub-groups of4 h,6 h,12 h and 24 h after treatment.At each interval,blood samples were obtained via jugular vein for detecting blood oxygen saturation (Sjv02)and blood lactate(LA).The blood oxygen saturation(Sa02)of ventral aorta was also measured.Arteriovenous oxygen content difference (AVD02) and oxygen extraction fraction (OEF) were studied.These four variables were analyzed and compared between two groups.Results The AVD02 and OEF in sepsis group were higher than those in control groups of 3 h,6 h and 12 h (P<0.05) ,but lower than those in control group of24 hours (P<0.05).The Sjv02 in sepsis group was lower than that in control groups of 3 h,6 h and 12 h (P<0.05),but increased to that in control group of 24 h (P>0.05).LA in sepsis group was higher than that in control group in each interval (P<0.05).Conclusions In early stage of sepsis,cerebral perfusion,cerebral oxygen supply and cerebral oxygen extraction increase.The global oxygen metabolic variables(Sjv02,AVD02 and OEF)and the level of LA can be used to objectively and accurately evaluate the cerebral oxygen metabolic dysfunction in early stage of sepsis.

The theoretical foundation and scientific connotation of spirit-regulating and pain-relieving acupuncture method as well as its clinical application for pain are discussed. During spirit regulation, attention should be paid on regulating heart and brain, while acupoints should be selected mainly from the Heart Meridian, Pericardium Meridian and Governor Vessel. It has significant efficacy for refractory pain in clinical treatment. Spirit-regulating and pain-relieving acupuncture method is development of acupuncture treating spirit, and it is an important method for pain in clinic. Improvement on sensitization of pain center and brain function is considered as one of the mechanisms in spirit-regulating and pain-relieving acupuncture method.
