OBJECTIVETo investigate the efficacy of autologous peripheral blood hematopoietic stem cell transplantation(auto-PBHSCT) combined with adoptive immunotherapy for patients with B lymphocyte malignant lymphoma(ML).

METHODSA total of 110 cases of ML treated with adoptive immunotherapy after auto-PBHSCT from January 2000 to December 2009 were enrolled in adoptive immunotherapy group (treated group), while 74 cases of ML treated without adoptive immunotherapy after auto-PBHSCT from January 1995 to December 1999 were used as control group. The efficacy of 2 groups were analyzed and compared, 110 case of ML in treated group included 78 cases of non-Hodgkin's lymphoma(NHL), 32 cases of Hodgkin's lymphoma(HL),74 cases of ML in control group included 52 NHL and 22 HL. All of the patients were treated sequentially with chemotherapy regimens for 6 courses. After that, all the patients received auto-PBHSCT. After hematopoietic reconstruction, the patients in treated group were given 6 courses of adoptive immunotherapy(rhIL-2 100 WU/day for 10 days monthly for each course), while the patients in control group were not given immunotherapy. All the patients were followed-up for more than 5 years.

RESULTSThere was one patient in each group, who died of liver failure and cerebral hemorrhage respectively within 3 and 2 months, and all the other patients achieved hematopoietic reconstruction. Following-up for 1, 3, 5 years, the disease-free survival (DFS) rate in treated group was 97.3%,93.6%,87.3% while 91.9%, 73.0%, 64.9% in control group. Following-up for 3 and 5 years, there was very significant difference in DFS between 2 groups(P<0.01). The 1,3 and 5 year DFS rate of patients in stage I/II and III/IV in the treated group were 100%,100%,91.7% and 96.5%,91.9%,86.0% respectively while DFS of control group was 100%, 93.3%, 86.7% and 89.8%, 67.8%, 59.3%, there was a significant difference in 3 and 5 years DFS of III/IV stage patients between 2 groups (P<0.01). The 1,3 and 5 year DFS rate of HL patients were 100%, 93.8%,84.4% in treated group and 100%,72.7%,59.1% in control group respectively. There was significant difference in 3 and 5 years DFS of HL between 2 groups (P<0.05). The 1,3 and 5 year DFS rate of stage I/II HL patients were 100%,100%,88.9% in treated group and 100%,100%,80.0% in control group. The 1,3 and 5 year DFS of HL patients in stage III/IV was 100%,91.3%,82.6% and 94.1%,64.7%,52.9% respectively. There was significant difference in 3 and 5 years DFS of III/IV stage of HL patients between 2 groups (P<0.05). The 1,3 and 5 year DFS rate of NHL patients is 96.2%, 93.6%,88.5% in treated group and 90.4%,73.1%,65.4% in control group respectively. There was a significant difference in 3 and 5 years DFS of NHL between 2 groups(P<0.01). The 1,3 and 5 year DFS rate of stage I/II NHL patients was 100%, 100%, 93.3.9% in treated group and 100%, 90%, 90.0% in control group, respectively. The 1,3 and 5 year DFS of NHL patients in stage III/IV is 95.2%, 92.1%,87.3% and 88.1%,69.0%, 59.5% respectively. There was significant difference in 3 and 5 years DFS of III/IV stage NHL patients between 2 groups (P<0.05).

OBJECTIVETo study the character of welder's pneumoconiosis on CT, pathology, and lung function.

METHODSTo contrast 185 welder's pneumoconiosis and 115 silicosis on CT, pathology, and clinical characters which were diagnosed between Jan 2008 and Dec 2013. Chest X-ray and lung function of 39 welder's pneumoconiosis patients were followed up after diagnosed 4~6 years later.

RESULTSAverage age and working years of welder's pneumoconiosis were 36.7 and 11.5, less than silicosis patients 58.8 and 22.1, respectively (P<0.05). Of all 185 welder's pneumoconiosis 98.4% were of stage I and no stage III, while in silicosis group stage I, stage II and stage III were 56.5%, 22.6% and 20.9%, respectively. The ratio differences between the two groups were statistically significant,P<0.05. 82.7% of welder's pneumoconiosis patients were observed pathologically moderate or above dust deposition in lung tissue while interstitial fibrosis level was just mild (97.6% patients) or no fibrosis (2.4% patients). By contrast, 60.0% silicosis patients pathologically showed moderate or above dust deposition while 77.8% were of moderate or above fibrosis. CT findings in welder' s pneumoconiosis were diffuse branching linear structure (38.9%), low density consistent size centrilobular micronodules (19.5%), or both (30.8%). Poorly-defined ground-glass attenuation centrilobular micronodules or widely ground glass shadow were observed in 6.4% welder's pneumoconiosis patents. 30.8% patients failed to reach the original stage when 39 welder's pneumoconiosis followed up chest radiograph.

CONCLUSIONChanges in welder's lung caused by welding fume were not only siderosis, but also interstitial fibrosis.

OBJECTIVETo investigate the clinical effects of plate and xenogenic bony plate for the treatment of nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing.

METHODSFrom February 2006 to June 2013, 21 cases with nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing were treated with femoral plate and contralateral xenogenic bony plate. There were 12 males and 9 females with an average age of 34.8 years old (ranging from 18 to 62 years). The time of nonunion was 9 to 18 months (averaged 12.8 months). The clinical outcomes of the treatment were evaluated by Merchan assessment.

RESULTSAll of the patients were primary healing, and on complications such as infection,fat embolism, internal fixation breaking or rotational deformity, shortening were occurred. All the cases were followed up for 13.2 months (ranging from 8 to 24 months). Nineteen cases were bone healed,the time of union averaged 6.2 months (ranging from 4 to 9 months). Two cases appeared delayed union and gained bony union after 7 to 13 months' observation. According to the criterion of Merchan,the results were excellent in 13 cases, good in 6 cases, poor in 2 cases.

CONCLUSIONTreatment of nonunion of femoral shaft fracture after initial locked intramedullary fixation with plate and xenogenic bony plate has advantages of high curative rate and low complications, good postoperative function recovery, it is a reliable treatment to elevate the stability of fixation and promote the osteogenesis.

BACKGROUNDGender is one of the risk factors accounting for the high prevalence of adolescent myopia. Considerable research results have shown that myopia incidence of female is higher than that of male. This study aimed to analyze the correlation between ocular parameters and serum estrogen level and to investigate the vision changes along with estrogen change in menstrual cycle of adolescent females.

METHODSA total of 120 young females aged between 15 and 16 years, diagnosed with myopia were recruited. Spherical lens, cylindrical lens, axis, interpupillary distance (IPD), and vision in each tested eye of the same subject were measured by automatic optometry and comprehensive optometry, with repetition of all measurements in the menstrual cycle of the 2 nd or 3 rd days, 14 th days, and 28 th days, respectively. Serum estradiol (E 2 ) levels were assayed by chemiluminescence immunoassay at the same three times points of the menstrual cycle mentioned above.

RESULTSIn young females with myopia, the spherical lens showed a statistically significant difference among all different time in menstrual cycle (all P < 0.0001). The cylindrical lens, axis, and IPD were changed significantly during the menstrual cycle (P < 0.05). The vision of the three different time points in menstrual cycle had a significant difference (χ2 = 6.35, P = 0.042). The vision during the 14 th and 28 th day was higher compared to that on the 2 nd or 3 rd days (P = 0.021). Serum E 2 levels were significantly different at different time points in menstrual cycle (P < 0.05). E 2 levels reached its maximum value on the 14 th day and the minimum value on the 2 nd or 3 rd day.

CONCLUSIONSIn adolescent females, the spherical lens and other related ocular parameters vary sensitively with different levels of E 2 in menstrual cycle. Vision in late menstrual stage is significantly higher than that in premenstrual stage.

BACKGROUNDInfections remain a major cause of therapy-associated morbidity and mortality in children with acute lymphoblastic leukemia (ALL).

METHODSWe retrospectively analyzed the medical charts of 256 children treated for ALL under the CCLG-2008 protocol in Beijing Children's Hospital.

RESULTSThere were 65 infectious complications in 50 patients during vincristine, daunorubicin, L-asparaginase and dexamethasone induction therapy, including microbiologically documented infections (n = 12; 18.5%), clinically documented infections (n = 23; 35.3%) and fever of unknown origin (n = 30; 46.2%). Neutropenia was present in 83.1% of the infectious episodes. In all, most infections occurred around the 15 th day of induction treatment (n = 28), and no patients died of infection-associated complications.

CONCLUSIONSThe infections in this study was independent of treatment response, minimal residual diseases at the end of induction therapy, gender, immunophenotype, infection at first visit, risk stratification at diagnosis, unfavorable karyotypes at diagnosis and morphologic type. The infection rate of CCLG-2008 induction therapy is low, and the outcome of patients is favorable.

To investigate the role and possible molecular mechanism of astrocytes in inflammation and amyloid β-protein (Aβ) formation, in this research, by using LPS to stimulate cultured rat astrocytes in vitro with or without anti-Toll-like receptor 4 (TLR4) antibody pretreatment, we first detected the TLR4, TNF-α, IL-1β, β-amyloid precursor protein (β-APP) and β-site APP clearing enzyme 1 (BACE1) mRNA with real-time PCR, and TLR4, NF-κB/P65 protein in cultured astrocytes by Western blot, and then further probed the translocation of NF-κB/P65 using immunofluorescence and the contents of TNF-α, IL-1β and Aβ in culture supernatant through ELISA. We found that all of these indexes increased at different degrees after LPS-stimulation. However, if pretreatment with anti- TLR4 antibody, such stimulating effects of LPS on the nuclear translocation of NF-κB/P65 and TNF-α, IL-1β, Aβ contents in astrocytic culture supernatant were reduced significantly or disappeared in comparison with the group with only LPS-administration. Our results suggest that TLR4 in astrocytes might play an important role in the inflammation and Aβ formation through the TLR4/NF-κB signaling pathway, thus providing new knowledge and understanding of the inflammatory hypothesis of AD pathogenesis.

OBJECTIVETo objectively evaluate the efficacy and safety of Yimusake Tablet in the treatment of premature ejaculation (PE) through a multi-centered large-sample trial.

METHODSWe conducted a multi-centered, open, fixed-dose, and self-compared clinical trial among 300 patients with diagnosed PE. The trial lasted 12 weeks, including 4 weeks without any medication and 8 weeks of treatment with Yimusake Tablet, 2 pills (1 g) per night. We observed the intravaginal ejaculation latency time (IELT) before and after treatment, evaluated the safety of medication, and performed a questionnaire investigation on the patients' satisfaction.

RESULTSOf the 300 PE patients, 288 accomplished the clinical trial. The patients ranged in age from 22 to 60 years, averaging at 31.6 years. The mean IELT of the patient was 62.5 seconds at baseline, 168.9 seconds after 4 weeks of treatment with Yimusake Tablet, and 222.2 seconds after 8 weeks of medication. Among the 157 patients with normal erectile function (IIEF >21), the mean IELT was 71.4 seconds before treatment, 147.4 seconds after 4 weeks of medication, and 172.5 seconds after 8 weeks of medication. The patients' satisfaction was significantly increased after treatment. Those complicated by mild to moderate erectile dysfunction achieved different degrees of improvement in the IIEF-5 score, with a mean increase of 3.8. Only a few patients experienced mild adverse events, including constipation, dry mouth, nose bleeding, abdominal pain, and lumbosacral pain, which were all relieved without drug withdrawal.

CONCLUSIONYimusake Tablet is a safe and effective medicine for the treatment of PE.

OBJECTIVETo evaluate the iodine nutrition level of population in Zhejiang province and to analyze the relevant influencing factors from 2009 to 2011.

METHODSFrom October 2009 to October 2011, a total of 19 517 subjects were recruited in this cross sectional survey, by multistage stratified cluster random sampling method. The subjects were all living over three years in Zhejiang province. The basic information and life styles were interviewed by questionnaires; and the samples of drinking water, edible salt and urines were separately collected from the subjects to test the content of iodine. In total, 16 228 subjects answered the questionnaire, and 265 samples of drinking water, 7811 samples of edible salt and 19 517 samples of urine were collected. Then, we analyzed the distribution of iodine in water, edible salt and urine samples, as well as the relevance.

RESULTSThe median (25% - 75% percentile) of water iodine was 2.42 (1.17 - 6.28) µg/L in drinking water among Zhejiang residents; while separately 2.79 (1.60 - 6.87) µg/L in city and 2.04 (1.03 - 5.29) µg/L in country side (Z = 2.07, P < 0.05). The figures turned out to be 2.17 (1.22 - 5.73) µg/L, 2.77 (1.88 - 6.87) µg/L, and 1.40 (0.77 - 5.65) µg/L, respectively, in coastal areas, coastal periphery areas and inland areas (χ(2) = 11.16, P < 0.05). The median (25% - 75% percentile) of salt iodine was 28.80 (22.93 - 32.40) mg/kg; while separately 29.00 (24.50 - 32.60) mg/kg and 28.50 (13.90 - 32.29) mg/kg in city and country side (Z = 6.32, P < 0.05). The figures turned out to be 25.19 (0.00 - 30.20) mg/kg, 29.00 (26.60 - 31.70) mg/kg and 32.40 (28.94 - 36.30) mg/kg, respectively, in coastal areas, coastal periphery areas and inland areas (χ(2) = 1581.62, P < 0.05). The coverage rate of iodized salt was 79.54% (6213/7811) in all province. The urinary iodine median was 160.74(97.20 - 247.00) µg/L, while the urinary iodine median in pregnant women was 137.99 (82.40 - 215.30) µg/L, lower than the recommended optimal levels, which was 150 - 249 µg/L. The figures turned out to be 153.45(92.00 - 237.50) µg/L in city and 168.00 (102.18 - 257.00) µg/L in country side (Z = -9.25, P < 0.05); while in coastal, coastal periphery place and inland areas, the median were separately 156.00 (94.29 - 242.80) µg/L, 150.14 (94.70 - 227.00) µg/L and 187.70 (109.00 - 276.80) µg/L (χ(2) = 194.12, P < 0.05). The analysis of relevance between urine iodine, water iodine and iodized salt showed that the urine iodine would increase as long as the iodized salt increased; and the difference had statistical significance (χ(2) = 440.88, P < 0.01). And there were no relevance between urine iodine level and the water iodine level (χ(2)cmh = 0.57, P = 0.45). The analysis of the influencing factors showed that education background (χ(2) = 14.17, P < 0.05), different styles of career (χ(2) = 16.15, P < 0.01) and diet habits (χ(2) = 108.63, P < 0.01) could influence the level of urine iodine.

CONCLUSIONIodine was deficient in Zhejiang province. The nutrition level of iodine was fine in Zhejiang in 2009, however, the coverage rate of iodine was commonly low in coastal areas, especially the pregnant women suffered from iodine deficiency. In our study, the factors influencing the urine iodine level included iodized salt, age, education background and diet habits.
