The complex field cure instrument is a new medical instrument with which an experiment was carried out. Rats were continuously irradiated by the complex field for 90 days, with a day's total dose of 285.9 M.T.G. while other rats weren't irradiated for control group. The animals were respectively killed at 7d, 14d, 30d, 60d and 90d, and their blood samples were taken for cell and humoral immune analysis. The results show that values of lymphocyte transform rate, soluble receptor (SIL-2R), total hemolytic complement levels (CH50) and immunoglobulin (A.G.) after irradiation are more than those of the control group having proved that the instrument may improve immune function of rats.

Objective:To investigate the expression and clinical significance of B7-H3 and IL-21 in serum of patients with HBV-related primary liver cancer.Methods: Gathering 121 cases of HBV-related patients,50 cases of primary hepatic carcinoma of them were considered as hepatic carcinoma group,71 cases of benign group including 12 cases with acute hepatitis,21 cases of chronic moderate to severe hepatitis,20 cases of compensatory phase cirrhosis,18 cases of decompensated cirrhosis and 20 cases of healthy persons in the same period as normal control.The content of serum B7-H3 and IL-21 were detected by ELISA.HBV DNA quantitative results were analyzed by Quantitative Real-time PCR.Results: The levels of B7-H3 and IL-21 in patients with primary hepatic carcinoma were (207.60±57.16)ng/ml and(2 357.28±805.01)pg/ml,respectively,which were significantly higher than those of the normal control subjects(P<0.001).Comparison with the normal control subjects,the content of B7-H3 and IL-21 in serum of patients with different clinical types in the benign group increased significantly(P<0.001).B7-H3 and IL-21 were positively associated with each other in serum of patients with HBV-related primary liver cancer.The expression of sB7-H3 was not significantly correlated with the degree of HBV DNA replication.The expression of IL-21 was correlated with HBV DNA replication in patients with HBV associated hepatocellular carcinoma,but was not significantly correlated with the degree of HBV DNA replication.Conclusion: HBV-related primary hepatic carcinoma express sB7-H3 and IL-21 with high level.The continuous high expression of sB7-H3 and IL-21 in the body may be related to the development and prognosis of the patients.

OBJECTIVETo investigate the effect of short hairpin RNA (shRNA) targeting survivin on adhesion and invasion of human colon carcinoma cell line SW480 in vitro.

METHODSAccording to the sequence of the coding region of survivin gene, two strings of 19 nucleotides of inverted sequence flanking the loop sequence of two complementary 9-base oligonucleotides were designed and synthesized to prepare the hairpin construct as the DNA templates for the target shRNA. The shRNA templates were cloned into shRNA expression vector pRNAT-U6.1/Neo, and the resulted vector pRNAT-U6.1/Neo-survivin was transfected into SW480 cells using Lipofectamine 2000. Western blotting was performed to evaluate survivin gene silencing induced by shRNA transfection at the protein level, and the biological behaviors of the SW480 cells were investigated by cell-matrix adhesion, invasion and gelatin-zymography assays.

RESULTSWestern blotting revealed significantly lowered survivin protein expression in transfected SW480 cells, and survivin gene silencing induced by shRNA significantly suppressed the metastatic potential of SW480 cells in association with suppressed MMPs activity.

CONCLUSIONSSurvivin may play an important role in modulating human colorectal carcinoma cell invasion and metastasis, and survivin gene silencing can inhibit human colorectal cancer cell invasion and the production of MMP-2 and MMP-9. Survivin may affect invasion and metastasis of human colorectal carcinoma cells via regulating the production of MMPs.

OBJECTIVETo explore the point specificity of eye-acupuncture and the mechanism of eye-acupuncture on diarrhea-predominant irritable bowel syndrome (D-IBS).

METHODSForty male Wistar rats of SPF grade were randomly divided into a normal group, a model group, a eye-acupuncture point (AA) group and a non-point (NA) group. The D-IBS rat model was established with the combination methods of the chronic stress and binding limbs. The AA group was treated by acupuncture at "low energizer area", "large intestine area", "liver area" and "spleen area", and the NA group by acupuncture at 3 mm apart from the same points area mentioned above, and the normal group and the model group with no intervention. The rate of feces moisture content was detected. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA of aquaporin 8 (AQP 8) in colon. Protein expressions of the vasoactive intestinal peptide (VIP) and AQP 8 in colon were detected by SABC immunohistochemistry method.

RESULTSCompared with normal group, the rate of feces moisture content at the 18th and 25th days, VIP protein in colon mucosa, myenteric nerve plexus and hypo-mucosa nerve plexus increased significantly (all P < 0.01), and AQP 8 mRNA in colon mucosa decreased significantly in model, AA and NA group (P < 0.05, P < 0.01); AQP 8 protein in colon mucosa decreased significantly in model group and NA group (both P < 0.01). Compared with model group, the rate of feces moisture content at the 25th day and VIP protein in colon mucosa decreased significantly (P < 0.01, P < 0.05), and AQP 8 mRNA and protein increased significantly (P < 0.05, P < 0.01) in AA group. Compared with AA group, the rate of feces moisture content at the 25th day and VIP protein in colon mucosa increased significantly (both P < 0.01), and AQP 8 mRNA and protein decreased significantly (both P < 0.01) in NA group.

CONCLUSIONEye-acupuncture has a good therapeutic effect on D-IBS. It is suggested that one of the mechanism is relate to increase AQP 8 in colon tissue and restrain the expression of VIP. Non-point area of eye-acupuncture has no obviously therapeutic effect and so to illustrate the point specificity of eye-acupuncture.

OBJECTIVETo isolate and culture tumor stem cells from glioma tissues obtained at surgical operation and to study their biological characteristics.

METHODSGlioma tissues obtained from surgically resected specimens of 8 patients were fully chopped, trypsinized, and filtered to prepare single cell suspensions. The cells were cultured in serum-free medium with EGF, LIF and bFGF. CD133(+) cells were purified by magnetic cell sorting, and cultured continuously in vitro to obtain tumor cell spheres. Tumor stem cells of the 5th passage were induced to differentiate with 10% FBS, and expression of cell differentiation markers such as Nestin, MAP2, GFAP was evaluated with immunocytochemistry techniques.

RESULTSCD133(+) cells were successfully separated and cultured from one anasplastic mixed astrocyte-ependymocyte type glioma specimen. These cells maintained a sphere-like growth status in vitro (3 months, 14 passages), and can self-renew, proliferate and conditionally differentiate into MAP2(+) and GFAP(+) cells. However, CD133(-) cells did not possess these properties.

CONCLUSIONGlioma tissue contains tumor stem cells. Those cells can be cultured and passaged in vitro for a long term, and therefore to offer new approaches for studying cellular and molecular biology of glioma.

OBJECTIVETo explore the morphology, immunophenotype, cytogenetics and clinical features of TCF3-PBX1 fusion gene positive adult acute lymphoblastic leukemia (ALL).

METHODSR banding was used to analyze conventional cytogenetics (CC), interphase fluorescence in situ hybridization (iFISH) and RT-PCR to detect the TCF3-PBX1 fusion gene, and flow cytometry to immunophenotype. The clinical and laboratory features and long-term follow-up of the patients were analyzed.

RESULTSThe incidence of 19 TCF3-PBX1-positive adult ALL was 3.13% of total ALL patients. Of them, 12 and 7 cases were diagnosed as L(1) and L(2) morphology respectively; 7 cases with balanced translocation of chromosome 1 and 19; 10 with der(19) t(1;19) formed from unbalanced translocation and 2 with normal karyotypes. TCF3-PBX1 fusion gene was detected by RT-PCR in 9 cases, and by iFISH in 17. 16 cases were B-phenotype and the other 2 T-phenotype; 17 cases had lymph node, spleen or liver infiltration. Of 18 patients received chemotherapy, 17 (94.7%) achieved complete remission (CR); the median relapse-free survival (RFS) and median overall survival was 3.2 months and 7.2 months, respectively.

CONCLUSIONSTCF3-PBX1-positive adult ALL had unique clinical and pathological features with high remission rate, high relapse rate and short survival time and should be considered to receive intensified treatment strategies. iFISH combined with CC and RT-PCR can increase the detection rate of t(1;19)/TCF3-PBX1 fusion gene.

BACKGROUND AND OBJECTIVEIn Guangxi province, from 1970s to 1990s, the mortality of primary liver cancer (PLC) ranked the first among a variety of malignant tumors. Investigating the epidemiological characteristics of PLC is very important for developing reasonable and effective treatment strategy, allocating health resources rationally, and evaluating the quality of PLC prevention and control. This study was to analyze the mortality and epidemiological characteristics of PLC in Guangxi province between 2004 and 2005.

METHODSMulti stage stratified cluster random sampling method was used to select 9 counties (cities or urban areas) as sample points. The residents' death causes between 2004 and 2005 were analyzed, and the epidemiological characteristics of PLC were investigated.

RESULTSIn the period of 2004-2005, the crude mortality of PLC was 34.39/100,000 in Guangxi province population (55.30/100,000 in men and 13.21/100,000 in women). The national population standardized mortality in 1964 was 22.17/100,000. The man to woman ratio of mortality was 4.19:1. PLC ranked as the first death cause among a variety of malignant tumors, and PLC related death accounted for 30.70% of all tumor related death cases. Age specific mortality of PLC was increased with age, rising significantly from 30 year old (from 25 year old in men and from 40 year old in women), and reached a peak at 75 year old.

CONCLUSIONSThe mortality of PLC shows a decreasing trend in Guangxi province in the early 21st century, and the starting age of PLC death peak postpones about 10 years than that in 1990s. It shows that the comprehensive prevention and control measures of PLC implemented in Guangxi province are fruitful. However, the PLC mortality in Guangxi province is still significantly higher than the national average level, and it still ranks as the first death cause in a variety of malignant tumors in Guangxi province. PLC mainly occurs in middle aged and elderly people. The prevention and treatment research of PLC still has a long way to go.

OBJECTIVE: To study the significance of the level of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) in serum and bronchoalveolar lavage fluid (BALF), Acute Physiology and Chronic Health Evaluation II (APACHE II) score, and Sequential Organ Failure Assessment (SOFA) score in evaluating the conditions and prognosis of children with severe pneumonia. METHODS: A total of 76 children with severe pneumonia who were admitted from August 2017 to October 2019 were enrolled as the severe pneumonia group. According to the treatment outcome, they were divided into a non-response group with 34 children and a response group with 42 children. Ninety-four children with common pneumonia who were admitted during the same period of time were enrolled as the common pneumonia group. One hundred healthy children who underwent physical examination in the outpatient service during the same period of time were enrolled as the control group. The serum level of sTREM-1, APACHE II score, and SOFA score were measured for each group, and the level of sTREM-1 in BALF was measured for children with severe pneumonia. The correlation of the above indices with the severity and prognosis of severe pneumonia in children was analyzed. RESULTS: The severe pneumonia group had significantly higher serum sTREM-1 level, APACHEII score, and SOFA score than the common pneumonia group and the control group (P<0.05). For the children with severe pneumonia, the non-response group had significant increases in the levels of sTREM-1 in serum and BALF and SOFA score on day 7 after admission, while the response group had significant reductions in these indices, and there were significant differences between the two groups (P<0.05). Positive correlation was found between any two of serum sTREM-1, BALF sTREM-1, and SOFA score (P<0.05). APACHE II score was not correlated with serum sTREM-1, BALF sTREM-1, and SOFA score (P>0.05). CONCLUSIONS The level of sTREM-1 in serum and BALF and SOFA score can be used to evaluate the severity and prognosis of severe pneumonia in children.
