OBJECTIVETo evaluate the correlation between standardized uptake valus (SUV) of 18F-fluorodeoxyglucose (18 F-FDG) of tumor at PET/CT examination and the expression of glucose transporter-1 (Glutl) and Ki-67 in esophageal cancer.

METHODS56 patients with esophageal cancer were evaluated with 18 F-FDG PET/CT examination before operation. The expression of Glut1 and Ki-67 antigen in the tumor tissues was detected by immunohistochemistry after operation.

RESULTS(1) Positive rate of Glutl and Ki-67 expression in esophageal cancer tissues was 100% , respectively. There was a positive correlation between the expression of Glutl and Ki-67 and the clinical stages and differentiation of the tumor. The more the tumor and the clinical stages were advanced and the lower was the tumor differentiation, the more Glutl and Ki-67 were expressed. (2) There were abnormal radioactive high uptake regions on PET/CT imaging of esophagus in the 56 patients, which were confirmed by pathology as the primary carcinoma. The SUV was higher than 2. 5. There was a gradually increasing tendency in SUV along with the lowering of the tumor differentiation and the advance of clinical stages. (3)There was a correlation between the expression of Glutl, Ki-67 and the SUV, the more Glutl and Ki-67 were expressed, the higher the SUV of tumor 18F-FDG at PET/CT examination was in esophageal tumor tissues.

CONCLUSIONThere is a widespread expression of Glutl in esophageal cancer tissues, and the SUV may be used to indirectly evaluate the proliferative capacity of esophageal cancer.

Objective To understand the current status of paragonimiasis epidemic in western mountain areas in Hubei Prov-ince. Methods Four counties(cities)of Western Hubei Province(Xingshan,Enshi,Yunxi,Baokang)were selected as the investigation sites for active surveillance. Crabs were captured and the metacercariae of Paragonimus were detected. Meanwhile, the blood samples were collected from the residents in the surveillance sites and the unique IgG and IgM antibodies against Para-gonimus in the sera were detected by ELISA. In addition,a questionnaire survey about knowledge and behavior of prevention and control of paragonimiasis was taken among the residents. Results A total of 1143 residents were investigated in the active surveillance,the total positive rate of the serology test was 1.84%(21/1143),while the rates of the male and the female were 1.78%(10/562)and 1.89%(11/581),respectively,with no statistical significance between them(χ2=0.002,P>0.05). The average weight of 161 fresh-water crabs captured was 11.72 g,with the positive rate of 9.32%(15/161)and the infective density of 7.07 metacercariae per positive crab. The positive rates of the male and female crabs were 11.54%(9/78)and 7.23%(6/83), respectively(χ2=0.884,P>0.05),and the infective densities were 6.67 and 7.67 metacercariae per positive crab,respective-ly. Totally 1143 residents were investigated by questionnaires,and 0.44%of them had the behavior of eating raw or half-done fresh-water crab,and 0.87% of them had the behavior of drinking un-boiled stream water. Conclusions The transmission chain of paragonimiasis still exists in the nature environment of mountain area in Western Hubei Province. The positive rate of the second intermediate host rebounds in some investigation sites. Therefore,the measures of continuous surveillance and health education should be taken to avoid the appearance of the prevalence or outbreak.

OBJECTIVETo study the clinical effificacy of electroacupuncture (EA) on treating knee osteoarthritis (KOA) of Shen ()-Sui () insuffificiency (SSI) syndrome type.

METHODSA total of 245 patients (279 knees) of KOA-SSI were randomly assigned to two groups by lottery: 141 knees in the treatment group and 138 knees in the control group. The treatment group was managed with EA at the dominant points of Neixiyan (Ex-LE4) and Waixiyan (Ex-LE5) as well as the conjugate points of Xuanzhong (GB39) and Taixi (KI3) for 30 min, once a day, with 15 days as one course; 2 courses were applied with a 5-day interval in between. The control group was treated with intra-articular injection of 2 mL hyaluronic acid into the affected joint every 7 days for 5 times in total. The clinical effects on the patients in different stages were observed, and their symptom scores of knee and contents of cytokines, including interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), prostaglandin E(2alpha) (PGE(2alpha)) and matrix metalloproteinases-3 (MMP-3), in the knee joint fluid were measured before and after treatment.

RESULTSThe study was completed in 235 patients (263 knees); four patients (7 knees) in the treatment group and six patients (9 knees) in the control group dropped out. Comparison of therapeutic effects (excellent and effective rates) between the two groups showed insignificant differences (P>0.05). Symptom scores of knee and contents of cytokines in the knee flfluid after treatment were lowered signifificantly in the patients of stage I-III in both groups (P<0.05 or P<0.01). However, the lowering of the total symptom score of knee in the patients of stage III in the treatment group was more signifificant (P<0.05).

CONCLUSIONSEA could effectively alleviate the clinical symptoms in KOA patients of stage III, showing an effect superior to that of hyaluronic acid. EA also shows action in suppressing the secretion of IL-1, IL-6, TNF-alpha, PGE(2alpha) and MMP-3 in the knee flfluid.

This study was aimed to detect the expression of leukemia stem/progenitor cell (LSPC) related genes (ABCB1, BMI-1, HOXB4) in the patients with acute leukemia, and to explore its clinical significance in acute leukemia. Bone marrow samples were collected from de novo acute leukemia patients (41 cases), patients with complete remission (CR, 16 cases) and the patients with non-malignant hematologic diseases (10 cases) respectively. And the expressions of ABCB1, BMI-1, HOXB4 genes were detected by comparative real-time quantitative PCR (RQ-PCR) with SYBR Green assay. The results showed that the expressions of ABCB1, BMI-1, HOXB4 were not detected in the patients with non-malignant hematologic diseases, but were higher (relative expressive level: 4.26 ± 2.26, 3.72 ± 1.91, 3.74 ± 2.38) in de novo acute leukemia patients and lower (relative expressive level: 2.14 ± 1.47, 2.07 ± 0.99, 1.47 ± 0.89) in the acute leukemia patients with CR (p < 0.05). The expressions of LSPC related genes were lower (relative expressive level: 1.77 ± 1.29, 2.09 ± 1.26, 1.78 ± 1.49) in the patients acquired CR/partial remission (PR) than those in the patients not acquired CR/PR (relative expressive level: 7.23 ± 1.78, 3.96 ± 0.92, 4.48 ± 2.57) (p < 0.01). Univariate analysis revealed that there were more cases with the expression of LSPC immunophenotype (CD34(+)CD38(-)CD96(+) and CD34(+)CD38(-)CD123(+)) and more hyperleukocytosis cases in patients with any higher expression of LSPC related gene (p < 0.05). Analysis of multiple parameters discovered larger significance (p < 0.01). It is concluded that there is a good relationship between LSPC related genes (ABCB1, BMI-1, HOXB4) and LSPC immunophenotype. The expression of LSPC-related genes is higher in de novo acute leukemia patients, and lower in patients acquired CR/PR. The patients with higher expressed LSPC-related genes display worse response to chemotherapy, lower CR/PR rate and higher leukocytosis, the analysis of multiple parameters may be a good method for assessing the therapeutic efficacy/prognosis of acute leukemia.

OBJECTIVETo investigate the feasibility, reliability and therapeutic effectiveness of adjuvant chemotherapy for advanced hepatocellular carcinoma (HCC) after orthotopic liver transplantation (OLT).

METHODSThe clinical data of adjuvant chemotherapy after OLT in 10 advanced HCC patients were studied retrospectively. FAP chemotherapy regimen was adopted calcium folinate (CF) 200 mg/m(2) and 5-Fluorouracil 500 mg/m(2) iv on D1 to D5, and doxorubicin 40 mg/m(2), cisplatin 30 mg/m(2) iv on D1, with 28 days as a cycle. The opportune time of chemotherapy, chemotherapy regimen, synergistic action between cytotoxic agent and immunosuppressive agent on liver and kidney and side-effects were preliminarily evaluated.

RESULTS7/10 patients are surviving, with the longest survival of 32 months, and the shortest 9 months. Three patients died after operation, two at 13 months, one at 20 months after OLT, all died of metastasis. The incidence of one year survival was 9/9. During the period of chemotherapy, the side-effects of adjuvant chemotherapy were moderate.

CONCLUSIONChemotherapy which is able to prolong the life-span of patients with advanced HCC after orthotopic liver transplantation is feasible and effective, the side-effects were mild. The choice of opportune time of chemotherapy might influence the outcome.
