Objective To study the value of serum CA 125. in the evaluation of pulmonary tuberculosis activity and treatment effect.Method This study included 90 subjects who were divided into three groups.Group 1 consisted of 30 patients with active pulmonary tuberculosis.Group 2 included 30 patients with inactive pulmonary tuberculosis.There were 30 healthy subjects in group 3.While measurement of serum CA 125. level were performed only once in groups 2 and 3,CA 125. levels were measured four times in group 1 before and after the treatment.Result The serum CA 125. concentration in group 1 was higher than in the other groups (P0.05).CA 125. levels in group 1 showed a significant decrease after treatment (P

Absctact: Objective To discuss the correlation between the TCM syndromes and the clinical pathological features of central air way non-small cell lung cancer.MethodsTCM syndromes were determined through inquiry and physical examination for 109 cases of lung cancer patients. Remaining specimens after excision and routine pathological examination were under HE staining for pathological diagnosis and study. The correlation between the TCM syndromes and the clinical pathological features was analyzed.ResultsThe histological types of central airway non-small cell lung cancer comprised squamous cell carcinoma (69/109, 63.3%), salivary type carcinoma (27/109, 24.8%), adenocarcinoma (10/109, 9.2%) and other rare carcinomas (adenosquamous, 2/109, 1.8%; sarcomatoid carcinoma, 1/109, 0.9%). The clinical and pathological features showed that the elderly, male, smoking patients most commonly suffered from squamous cell carcinoma, while the young, female, non-smoking patients suffered from salivary type carcinoma most frequently. The distribution characteristics showed that the qi-yin deficiency syndrome was most common in squamous cell carcinoma and salivary type carcinoma, accounting for 41.4% (29/70) and 40.7% (11/27) respectively; qi-deficiency and phlegm-dampness syndrome was most common in adenocarcinoma, accounting for 50.0% (6/12). TCM syndrome types were closely related to sex, to smoking history, and to Karnofsky score respectively, with statistical significance (P<0.05,P<0.01). The qi-yin deficiency syndrome was common in male, smoking patients, while the qi-deficiency and phlegm-dampness syndrome and yin-deficiency and heat-toxin syndrome were common in female and non-smokers. The qin-yin deficiency syndrome was common in patients of Karnofsky score≥60, and qi-deficiency and phlegm-dampness syndrome was most frequently found in <60 scores group.Conclusion The histological types of central air way non-small cell lung cancer are related to age, gender and smoking history of patients. Patients with different ages, genders and smoking histories distribute differently in TCM syndrome.

Objective:To investigate the expression of CXCL12-CXCR4 and VEGF-C in pancreatic cancer and relation to clinical pathology.Methods:The tissue samples including PAC,the cancerous peripheral tissues,the normal pancreatic tissues and peripheral lympho nodes were obtained from 30 patients with PAC.The expressions of CXCL12,CXCR4and VEGF-C proteins in these tissues were assayed by immunohistochemical staining.The expressions of CXCL12,CXCR4 and VEGF-C mRNA in PAC were also investigated by fluorescence quantitative real-time PCR.Results:In all the samples,the positive rates of CXCL12 protein in PAC,the cancerous peripheral tissues,the normal pancreatic tissues and peripheral lympho nodes were respectively 13.3%(4/30),46.7%(14/30),56.7%(17/30) and 50.0%(15/30).The positive rates of CXCR4 protein in PAC,the cancerous peripheral tissues,the normal pancreatic tissues and peripheral lympho nodes were respectively 80.0%(24/30),70.0%(21/30),26.7%(8/30) and 73.3%(22/30).The expression levels of CXCR4 mRNA in PAC tissues,the cancerous peripheral tissues and peripheral lympho nodes were higher than that in the normal pancreatic tissues(P

Objective To analyze the intratumoral and peritumoral microvessel density (MVD) and microlymphatic vessel density (MLVD) in pancreatic cancer and record the expression of vascular endothelial growth factor(VEGF)-C and VEGF-D. And to explore the significance of VEGF-C and VEGF-D during the lymphatic metastasis and development of pancreatic cancer. Methods The expression of VEGF-C and VEGF-D, VEGF-R3, CD34 were assayed by immunohistochemical staining in 30 cases of pancreatic cancer tissues. Results The positive rates of VEGF-C and VEGF-D protein in the central portion of tumors (30% and 16.7%) were significantly lower than those in the marginal portion (73.3% and 56.7%), P <0.01. The group with high expression of VEGF-C and VEGF-D in the marginal portion had significantly higher incidences of lymph node metastasis, lymphatic invasion and venous invasion( P <0. 01 ). MLVD in both of the VEGF-C and VEGF-D positive groups was higher than that in the negative groups( P <0. 01 ), and the lymph node me-tastasis increased. MVD in VEGF-C positive group was significantly higher than that in the negative group. MVD had no significant difference between VEGF-D positive and negative group ( P =0. 07). Conclusions The expression of VEGF-C and VEGF-D in the marginal portion of tumor is significantly correlated with lym-phatic metastasis in pancreatic cancer patients, and may induce lymphangiogenesis. VEGF-C may play an im-portant role in the regulation of angiogenesis and lymphangiogenesis in pancreatic cancer, and VEGF- D maybe only participate in the regulation of lymphangiogenesis.

Aim To investigate the effect of intestinal cholesterol absorption inhibitor Ezetimibe on lipid accumulation in RAW264.7 cells and identify the underlying mechanism.Method RAW264.7 cells were pretreated with the indicated concentrations of Ezetimibe (0,0.003,0.01 and 0.03 mol·L~(-1))for 24 hours or pretreated with the optimal concentration(0.03 mol·L~(-1))of Ezetimibe for different periods (0,6,12 and 24 h),followed by incubation with 50 mg·L~(-1) oxLDL for 24 hours,then the number of intracellular lipid droplets and lipid content were measured by using oil red O staining and HPLC; the expression of NPC1L1 was measured by Western blot.Results Pretreatment with indicated concentrations of Ezetimibe caused a concentration-dependent inhibition of intracellular lipid accumulation;pretreatment with 0.03 mol·L~(-1) Ezetimibe caused a time-dependent inhibition of intracellular lipid accumulation.It was noted that pretreatment with 0.03 mol·L~(-1) Ezetimibe for 24 hours inhibited CE by about 47%+0.1% compared with control group(oxLDL alone).Immunoblotting results showed that NPC1L1 was expressed in RAW264.7 cells and it was down-regulated after Ezetimibe treatment.Conclusions Ezetimibe causes concentration-dependent and time-dependent inhibition of lipid accumulation in RAW264.7 cells;it also reduces NPC1L1 expression in RAW264.7 cells.

Objective To investigate Fascin expression in human lung cancer tissues and its clinical significance.Methods Immunohistochemistry was performed in 62 patients with different histological types and clinical stages of lung cancer and 92 cases with other malignant tumors.Fascin positive rate in each group was calculated and the differences of pathological characters between the two groups were analyzed.Results Fascin expression in lung cancer tissues was significantly higher than that in normal lung tissues(P ＜ 0.05),its expression varied by different clinical stage of lung cancer tissue differentiation.As differentiation degree decreased,Fascin positive rate increased.Fascin expression was independent with age,sex,smoking history(P ＞ 0.05).Fascin expression had no significant difference between lung cancer group and other tumor group(P ＞ 0.05).Conclusions Fascin expression raising might be common in malignant tumors.Fascin expression in lung tissues indicated the possibility of lung cancer.In lung tissue,high expression of Fasein was a sign of poor differentiation and malignant status of lung cancer.

Objective To explore the changes of plasma endothelin-1 (ET-1), nitrousoxide (NO), blood gas analysis, and blood rheology in patients with chronic bronchitis (CB), pulmonary emphysema (PE) and pulmonary heart disease (PHD) at different periods.Methods The plasma ET-1, NO, blood viscosity, hematocrit (Hct) and aggregation index (AI) of patients in groups of CB, PE and PHD, and the subjects of the control group were tested and compared. Blood gas analysis of subjects in four groups also performed and compared. Each group had 40 cases.Results In PE and PHD patients, the ET-1 level was higher, the indexes of blood gas analysis and blood rheology were abnormal. When PE developed into PHD, the ET-1 and PaCO2 tended to increase, PaO2 tended to decrease. When CB developed into PE and PHD, the blood viscosity, pressure volume and AI tended to increase, but NO tended to decrease.Conclusion When CB developed into PE or PHD, ET-1, PaCO2 tend to increase and NO, pH, PaO2 tend to decrease; increased red blood cells, blood viscosity and AI become severe.

Objective To explore the biological function of rhoptry protein 38(ROP38)of Toxoplasma gondii,and to iden?tify the reactogenicity of the recombinant protein(rROP38). Methods The ROP38 was amplified by RT?PCR from T. gondii RH strain,and was cloned into prokaryotic expression vector pET?28a(+). The recombinant plasmid was transformed into E. co?li BL21(DE3)competent cells. Then the rROP38 was analyzed by SDS?PAGE and identified by Western blot. Results SDS?PAGE showed that rROP38 was efficient expression with a molecular weight of about 43 kD. Western blot showed that rROP38 reacted with antibody of His tag or human positive antibody,which indicated that ROP38 had good reactogenicity and could be a serological diagnostic antigen. Conclusion The study successfully obtains the rROP38 of T. gondii with good reactogenicity.

Objective To evaluate the role of multi-slice CT (MSCT) perfusion in early diagnosis of liver fibrosis. Methods Thirty-three subjects underwent CT perfusion of the liver. Among whom, 11 subjects were volunteers without hepatic disease and the other 22 subjects were pathologically confirmed with liver fibrosis who were further divided into slight (n= 10) and severe (n=12)liver fibrosis according to the lshak system. Parameters of CT perfusion were measured and compared among three groups. Results The mean hepatic arterial fraction in controls, light and severe fibrosis tended to increase with the severity of liver fibrosis[(18. 49 ± 9. 69) %, (19. 92 ± 6.01) % and (21.31±7.47)% ,respectively], and the mean mean transit time tended to decrease with the severity of liver fibrosis [(13.80 ± 2. 60) s, (12.35 ± 1.31) s and (12.19 ± 3.33) s, there was no significant difference in all parameters between any two groups (P>0.05). Conclusions Quantitative measurement of hepatic blood supply can be obtained by CT perfusion. Some parameters will be helpful in staging fibrosis to a certain extent. But its clinical usefulness for the evaluation of the early diagnosis may not be affirmed yet.

The present paper is aimed to observe the lateral attachment of the renal fascia (RF) in vivo with multidetector computed tomography (MDCT) scanning, and to discuss its diagnostic value. 121 healthy adults were adopted into this experiment. All images were obtained with MDCT and double phase enhancement scanning. Then we observed the lateral attachment of RF. In addition, we mad a fresh body specimen as anatomical basis. The study found that above the renal hilar plane (RHP), the anterior renal fascia laterally fused with the peritoneum of the liver on the right and the peritoneum of the spleen on the left,and the posterior renal fascia fused with the subdiaphragmatic fascia. The lateral attachment of the RF at the RHP and the lower renal pole(LRP)is divided into three types. The RF in Type I is about 47.9% (58/121) at the left RHP, while about 33.9% (41/121) at the right RHP. At the LRP of the kidney is about 55.3% (67/121) on the left, and about 42.1% (51/121) on the right. The RF in Type I is about 38.8% (47/121) on the left side at the RHP, about 26.4% (32/121) on the right side. At the LRP, left side about 27.3% (33/121), right side about 13.3%(16/121). The RF in Type III at the RHP is 13.3% (16/121) on the left side, and on the right side is about 39.7% (48/121). At the LRP, it is about 17.4% (21/121) on the left side, and about 44.6% (54/121) on the right side. MDCT can display the lateral attachment of the RF better as well as the outside connection of the retroperitoneal space.
