Objective To have insight into the epidemiological situation and to predict the possibilities for achieving the national goal of basic eradication or the WHO target of elimination of leprosy as a public health in the leprosy high- endemic areas in China. Methods Based upon the data during 1983- 1996 from the National Leprosy Recording and Reporting Surveillance System and using the appropriate mathematical models, the expected calendar year of reaching the national goal in terms of detection and prevalence rates and the WHO target of elimination under different conditions was predicted. Results Of 337 counties where the national goal of basic eradication of leprosy had not reached and 40 counties where the WHO goal of leprosy elimination had not achieved in 1996, the detection rates in calendar years followed the negatively exponential models with a significant goodness- of- fit in 67 and 11 counties, respectively. In the former, the national goal can be met in 6% of counties before the year 2000 or 34.4% before 2010 in terms of detection rate, or 31.3% before the year 2010 in terms of prevalence rate. In the latter, the WHO target can be met in 8- 10 counties within this century when the duration of disease was determined with the WHO definition. While the MB proportion among new cases increased by 10% , the target would be met one year later. However, at the same MB proportion, the change of the duration of completing the fixed treatment from PB 0.5 year and MB 2 years to PB 0.75 year and MB 3 years will result in the achievement of the goal 2- 10 years later. Conclusion The results imply that WHO goal of leprosy elimination can be reached in more than 95% of counties by the end of this century, but the national goal of achieving basic eradication of leprosy in more than 95% of counties by this century will not be met, indicating that leprosy control will go beyond the century in China.

Objective To observe the curative effect of condyloma acuminatum patients treated with differences of bacilli phlei injection after fulfufized and the effect of immunity function. Methods We compared curative effect and peripheral blood T lymphocyte subpopulation in the treatment group( 55 cases, 8 weeks, prior and posttreatment with differences of bacilli phlei only) and the control group (50 cases, 8 weeks, prior and post-treatment with recombinant human interferon α-2b only). Results Compared with the control group (24.0 %/41.7 % ), the treatment group(47.3 %/11.5 % ) had advantage in the terms of cure rate and relapse rate( P<0.05 ). CD+3, CD+4 ,CD4+/CD+8 increased and CD+8 decreased in two groups after treatment. CD+3 , CD+4, CD+4/CDs+ were significantly increased in treatment group compared with the control group after treatment(P<0.05), but CD+8 had no obvious difference in two groups(P>0.05). Conclusion Differences of bacilli phlei injection can prevent relapse of condyloma acuminatum and increase immunity function of patients.

Objective To determine the antigen-specific CTL in PBMC induced by a fusional family-gene vaccine of the immunoglobulin heavy chain variable gene framework region combined with the sequence of cytokine CM-CSF in vitro with MHC pentamer. Methods Peripheral blood samples were collected from two healthy donors and two patients. One was follicular lymphoma and another was hair cell leukemia. PBMC were isolated by density gradient centrifugalization with Ficoll and then subsequently differentiated into immature DCs (imDCs) induced by recombinant human GM-CSF and recombinant human IL-4. Gene gun was used to deliver the plasmids of the gene vaccine or the control plasmids into the imDCs. RT-PCR and ELISA assay were used to detect IgHVl-GM-CSF mRNA and GM-CSF in order to validate the transfection of the vaccine. After adding the cytokine cocktail, the imDCs became mature DCs. Then the mature DCs were co-cultured with lymphocytes from the blood samples for the induction of the antigen-specific CTL. The cultured cells were classified into vaccine group and control group and harvested at different time points of 0 d,7d, 17 d and 24 d after transfection. The subset of CD3+CD8+ T cells was analyzed by FCM assay. Finally, the CTL levels were detected with fluorescently labeled MHC pentamer antibody targeting vaccine epitopes. Results With the induction of cytokines, the imDCs with typical morphology were generated in PBMC. After delivering, the efficient expressions of the vaccine in the imDCs were determined by RT-PCR. And ELISA results also confirmed that GM-CSF was produced at a level of (28 ±6) ng/106 cells of the imDCs loaded with the vaccine, which was significantly different from that of control group (10 ± 3) ng/106 cells (t = 5. 191, P <0.01). FCM assay result showed that the CD3+ CD8+ T cells increased in a stepwise pattern during the culture. For control group, the levels at 0 d,7d, 17d and 24 d were ( 34. 24 ± 2. 72 )% , (46.06 ± 3.08)%, ( 65. 34 ± 4. 26 )% and (73.86 ±4.85 )% , respectively. For vaccine group, the results were (32. 28 ± 2. 08 ) % , (45. 32 ± 3. 81)% , ( 63. 37 ± 4. 21)% and (75. 01 ±3. 20)%. The differences between each time point had statistical significance (F = 176. 966 ,P <0.01) ,but there was no statistical differences between vaccine group and control group ( F = 0.657,P>0.05). The MHC pentamer analysis showed that the DCs loaded with IgHV1-GM-CSF fusional vaccine could efficiently induce the antigen-specific CTL response and the CTL levels increased gradually with the culture time, with the highest level of 4. 36% in the lymphoma blood and 3. 89% in the hair cell leukemia blood. Conclusions MHC pentamer assay could efficiently determine the antigen-specific CTLs response induced by the gene vaccine of family IgHV frame region in vitro. It could be a useful method for monitoring of anti-tumor cell immunity and evaluating of diagnosis and prognosis of the tumors in clinical application.

OBJECTIVETo study the hormonal and metabolic responses of fetal lamb during cardiopulmonary bypass.
METHODSSix pregnant ewes underwent fetal cardiopulmonary bypasses with artificial oxygenators and roller pumps for 30 minutes, which maintained the blood gas value at the fetal physiological level. The fetal blood pressure, heart rate, pH value and blood lactate levels were monitored. The levels of catecholamine, cortisol and insulin were measured pre-bypass and then again 30 minutes later. The blood glucose and free fatty acid levels were monitored continuously during the bypass. Fetal hepatic PAS staining was also carried out.
RESULTSThere were no changes before and during the bypass in fetal blood pressure, heart rate and blood gas. However, pH values decreased and blood lactate levels increased (P < 0.05). The fetal catecholamine and cortisol levels increased significantly (P < 0.01), while the levels of insulin did not change. The blood glucose and free fatty acid levels increased at the beginning of the bypass (P < 0.01), and then gradually slowed down during the bypass. The fetal hepatic PAS staining showed that hepatic glycogen was consumed in large amounts. After 30 minutes of bypass, the fetal lamb would not survive more than 1 hour.
CONCLUSIONThe fetal lamb has a strong negative reaction to cardiopulmonary bypass.

OBJECTIVETo investigate if there are microsatellite loci in the long arm of chromosome 6 that have close relationship with non-small cell lung cancer.
METHODSMultiple PCR approach was used to analyze the 18 loci in the long arm of chromosome 6. The PCR products were analyzed in PAGE, and then the electrophoresis maps were analyzed with Gene Scan(TM) and Genotyper(TM).
RESULTSThere were different frequencies of loss of heterozygosity (LOH) in different loci (varying from 3.85% to 38.45%). The total frequency of LOH in 41 gastric cancers was 58.5%(24/41). Eight loci with the LOH frequency higher than 20% were mainly located in 2 regions: 6q24 and 6q27. The accurate location is 6q24-6q25.3 [D6S1699(35%), D6S409(23.33%), D6S441(33.33%)] and 6q26-27 [D6S1550(38.45%), D6S264(20%), D6S1585(25%), D6S446(33.33%), D6S281(30.77%)].
CONCLUSIONThere may be tumor suppressor genes located in the region of 6q24 and 6q27, which have close relationship with non-small cell lung cancer.

Objective:To investigate the effects of CT simulation positioning and three-dimensional conformal radiotherapy combined with regimen of paclitaxel and cisplatin (TP) on serum squamous cell carcinoma antigen (SCC) level and prognosis in patients with advanced esophageal cancer.Methods:A total of 80 cases of advanced esophageal cancer patients in People′s Hospital of Xinjiang Uygur Autonomous Region from June 2016 to October 2017 were selected and randomly divided into treatment group and control group, with 40 cases in each group. The control group was treated with CT simulation positioning three-dimensional combined cisplatin and Docetaxel, and the treatment group was treated with CT simulation positioning three-dimensional combined TP regimen. The clinical efficacy, tumor marker levels [serum SCC, carcinoembryonic antigen (CEA), carbohydrate antigen-199 (CA-199), human cytokeratin 21-1 fragment (CYFRA21-1)], Karnofsky functional status (KPS) score, Quality of Life(QOL) score, progression free survival period and incidence of adverse reactions were compared between the two groups.Results:After treatment, the total effective rate in the treatment group was 70.00%, which was significantly higher than 55.00% in the control group ( P<0.05); the levels of serum SCC, CEA, CA-199 and CYFRA21-1 in the two groups after treatment were significantly lower than those before treatment ( P<0.05), and those in the treatment group were significantly lower than those in the control group ( P<0.05); after treatment, the QOL and KPS scores in the two groups were significantly higher than those before treatment ( P<0.05), and the scores in the treatment group were significantly higher than those in the control group ( P<0.05); The progression free survival time in the treatment group was significantly longer than that in the control group ( P<0.05); The incidence of adverse reactions in the treatment group was 15.00%, which had no significant difference compared with 25.00% in the control group ( P>0.05). Conclusions:CT simulation positioning three-dimensional combined with TP regimen in the treatment of advanced esophageal cancer has obvious effect, can effectively reduce the level of tumor markers, improve the patient′s physical function and quality of life, improve prognosis , and does not increase the survival rate of adverse reactions, which is safe and effective.
