OBJECTIVE: To evaluate the use and tendency of anti-rejection drugs in six cities in the Yangtze valley.METHODS: The consumption data for anti-rejection drugs in the Yangtze areas during the period 2004～2006 were analyzed statistically by the method of order of consumption sum.RESULTS: The anti-rejection drugs used in the Yangtze valley increased year by year,up 28.4% in 2005 and 23.9% in 2006 over the previous year.On the list of consumption sum for the six cities in Yangtze valley,the proportions for Shanghai over the 3 years were 67.1%,62.5% and 65.4%;those for Hangzhou were 12.6%,16.7% and 14.7%;5.3%,4.6%,4.6% for Nanjing;7.6%,9.0% and 7.4% for Wuhan;4.9%,4.5%,5.0%for Chendu,and 2.5%,2.7% and 2.9% for Chongqing.CONCLUSION: The consumption of anti-rejection drugs was unbalanced among the 6 cities in the Yangtze areas,but its clinical application was basically in line with the marketing of new drug both at home and abroad.The import drugs occupied the biggest market share,while the market share of the domestic drugs increased slowly but steadily.The prices for anti-rejection drugs were still very high,which should be lowered to reduce patients' economic burden.

The nutritional value of bread fortified with zinc, lysine, iron, and calcium was evaluated by biological method. The amount of the supplemented lysine, iron, calcium and zinc in the experimental diet was 0.3%, 0.008%, 0.3% and 0.008% respectively.32 Wistar rats were devided randomly into 4 groups; the control group was fed with ordinary bread and the other three groups were fed with bread fortified with lysine, Fe and Ca, or Zn or lysine, Ca, Fe and Zn respectively. All the rats in each group took thier respective diet and drank distilled water ad libitum.The results indicated that the body weight of the group fortified with zinc alone was increased more fast at the first two weeks, and then slow down, finally, slower than the control group obviously. The increase of body weight, FE, PER, NPU, BV, weight and length of long bones, iron status in the group fortified with lysine, iron, and Ca combind were better than the control group. The group, however, fortified with lysine, Fe, Ca and Zinc combined was the best among these four groups. It promoted the growth of the rats markedly and did not impede the utilization of iron, calcium and copper as well.

Primary hepatic lymphoma (PHL) is an extremely rare disease without any unified diagnostic criterion.The symptoms are usually nonspecific.Liver biopsy remains the most valuable tool for diagnosis of PHL.The predominant histology of PHL is diffuse large B-cell lymphoma.The therapeutic modalities are variable,including surgery,chemotherapy,radiotherapy,or combination of the various processes.This article described a 33-year-old man with diffuse large B-cell PHL who was treated at the Affiliated Cancer Hospital of Shanxi Medical Univeitity Blood Disease Diagnosis and Treatment Center in February 2014.The patient benefited from eight-cycle chemotherapy.At present,the patient is disease-free and undergoes regular follow-up.

Objective To access the effectiveness of withdrawing iodized salt on correcting the iodine excess in the population living in high iodine areas.Methods Before withdrawing iodized salt,2 twons were selected from each of 5 cities with water-borne iodine excess areas in Hebei province.All the selected towns were divided into 7 groups according to their iodine content in drinking water.Two villages wereselected from each group where urine samples of children aged 8 to 10 years old were collected to investigate the change of urinary iodine content of these children before and after withdrawing iodized salt.The urinary iodine content was determined using the method for determination of ammonium persulfate digestion arsenic cerium catalytic spectrophotometry (WS/T 107-2006).Correlation between children's urinary iodine and drinking water iodine was analyzed.Results Before and after withdrawing iodized salt,744 and 771 urine samples were collected from the examined children aged 8-10 years respectively.The overall median urinary iodine content (MUIC) of the examined children after withdrawing iodized salt (350.1 μg/L) decreased significantly than that of before withdrawing iodized salt (460.8 μg/L,U =3 127.8,P ＜ 0.05).After withdrawing iodized salt,the MUIC of the children decreased significantly in 8 of 12 villages (P ＜ 0.05).Before and after withdrawing iodized salt,the percentage of urine samples with iodine content above 300 μg/L was 76.7％ (571/744),58.5％ (451/771) respectively,with significant statistical difference (x2 =57.7,P ＜ 0.05).After withdrawing iodized salt,Children's MUIC also decreased significantly across gender and age (boys:558.5,351.6 μg/L,U =960,P ＜ 0.05; girls:522.9,355.5 μg/L,U =698,P ＜ 0.05; 8 years old:536.0,295.5 μg/L,U =529.5,P ＜ 0.01; 9 years old:386.2,323.2 μg/L,U =753.5,P ＜ 0.01; 10 years old:525.5,368.8 μg/L,U =521.5,P ＜ 0.05).The children's MUIC correlated positively with the median water iodine contert (MWIC) in the villages where they lived (r =0.951,P ＜ 0.01).Analyzed by linear regression,approximately 89％ of the variability in MUIC was associated with variability in MWIC.Conclusions Withdrawing iodized salt could only correct the iodine excess caused by consuming iodized salt in the population living in the areas with MWIC below 100 μg/L.In the areas with water iodine above 100 μg/L,intervention should be focused on seeking water with proper iodine content.

AIM: To illuminate the effect of SWI/SNF-related, matrix-associated, actin-dependent regulator of chromatin, subfamily b, member 1 (SMARCB1) in early diagnosis and prognosis of hepatocellular carcinoma (HCC) by determining the clinical expression of SMARCB1 in HCC tissue and benign liver tissue.METHODS: The specific target gene SMARCB1 was selected from these genes by using The Cancer Genome Atlas (TCGA).SMARCB1 expression in HCC tissue and benign liver tissue was measured by immunohistochemistry.Further statistical analysis of TCGA was performed to illuminate the role of SMARCB1 on HCC occurrence and progression.RESULTS: Compared with the benign liver tissue, immunohistochemical staining showed that SMARCB1 expression was significantly up-regulated in the HCC tissue (P<0.01).In addition, SMARCB1 expression was significantly associated with advanced tumor stage (P<0.05).The relation between SMARCB1 expression at mRNA level and clinical prognosis was analyzed.The results indicated that high SMARCB1 expression was an independent prognostic factor for HCC (P<0.05).CONCLUSION: SMARCB1 may play a part as a carcinogenic gene in tumorigenesis.We can distinguish primary HCC samples from non-malignant samples according to its different clinical expression.High SMARCB1 expression probably predicts poor outcome in HCC patients.

Objective:To explore the value of octreotide suppression test(OST) in predicting the efficacy of somatostatin receptor ligands(SRLs) in the treatment of active acromegaly.Methods:The clinical data of 76 patients with active acromegaly from 2011 to 2020 was retrospectively analyzed. OST was carried out as follows: After an overnight fasting and baseline sampling of growth hormone(GH), 100 μg octreotide was subcutaneously injected, and sampling for GH was obtained every 2 hours for 8 hours. All patients were treated with SRLs for at least 3 months. A good GH response is defined as a post-treatment random GH<1 μg/L or >80% fall compared with the baseline GH. A good insulin-like growth factor Ⅰ(IGF-Ⅰ) response is defined as IGF-Ⅰ<1.3 upper limit of normal(ULN) or >50% reduction compared with the baseline. If both GH and IGF-Ⅰ fulfill the criteria of a good response, it is defined as a good GH and IGF-Ⅰ response.Results:The baseline level of GH during OST was 15.00(6.38, 34.20) μg/L, the median time to reach the nadir GH was(3.65±1.65) hours, and the nadir GH level was 1.47(0.50, 4.19) μg/L. The median GH suppression rate was 89.12%(72.71%, 95.09%). When the cutoff value of GH suppression rate in predicting a good GH response was 89.32%, the area under the curve(AUC) was 0.74, with a sensitivity of 81.80% and specificity of 66.00%. When the cutoff value of GH suppression rate in predicting a good IGF-Ⅰ response was 93.14%, the AUC was 0.64, with a sensitivity of 50.00% and specificity of 75.60%. When the GH suppression rate was 90.71%, the AUC was 0.78, with the sensitivity of 83.30% and specificity of 70.00% in predicting a good GH and IGF-Ⅰ response. Compared with GH/IGF-Ⅰ non-responders, GH/IGF-Ⅰ responders displayed lower nadir GH during OST, higher GH suppression rate and IGF-Ⅰ reduction rate, and lower ratio of IGF-1 to ULN( P<0.05). Conclusion:GH suppression rate during the OST is a valuable predictor to evaluate the efficacy of SRLs in patients with acromegaly, with the highest sensitivity and specificity when the cutoff value is 90.71%.

Objective There is still a lack of effective clinical prognostic factors for predicting outcomes and guiding treatments in extranodal nasal-type NK/T-cell lymphoma (NKTCL).This study was aimed to investigate the clinical features and prognostic role of primary tumor burden (PTB).Methods A total of 1383 patients were recruited from ten hospitals, including 947 stage Ⅰ patients (68.5%), 326 stage Ⅱ patients (23.6%), and 110 stage Ⅲ-IV patients (8.0%).There were 751 patients (54.3%) presenting with high PTB (H-PTB).The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was conducted for survival difference analysis.Meanwhile, a multivariate analysis was performed using the Cox regression model.Results H-PTB was associated with high invasive potential, high frequency of B symptoms, advanced stage, regional lymph node involvement, lactate dehydrogenase elevation, and poor performance status.The patients with H-PTB had significantly lower 5-year overall survival (OS) and progression-free survival (PFS) rates than those with low PTB (L-PTB)(OS:50.2% vs.72.1%, P=0.000;PFS:41.8% vs.62.5, P=0.000).PTB was an independent prognostic factor for both OS (HR=1.851) and PFS (HR=1.755) according to the Cox multivariate analysis.Moreover, H-PTB was associated with significantly lower locoregional control (LRC) in early-stage NKTCL, and the 5-year LRC rate was 71.6% in patients with H-PTB and 84.3% in those with L-PTB (P=0.000).Conclusions H-PTB is associated with multiple adverse clinical features in NKTCL, and it is an independent indicator for poor outcomes and LRC.H-PTB can be used as a reliable indicator for risk stratification and treatment decision.

Objective To investigate the neurodevelopmental toxicity of ACR by studying the expression of DCX and GAP-43 in the hippocampal dentate gyrus of rats after maternal exposure to acrylamide. Methods Pregnant rats were randomly divided into low-dose ACR(4.5 mg/kg),medium-dose(9 mg/kg),high dose groups(18 mg/kg)and the control group(0 mg/kg),8 in each group,and were exposed to toxicant from gestation-al day 15 to postnatal day 13. All rats and their pups were killed on postnatal day 14. ABC immunohistochemistry was used to detect the expression of GFAP in the hippocampus of mother rats and offspring. Results Compared with the control group,the expression of DCX and GAP-43 in hippocampus dentate gyrus of the pregnant rats in middle and high dose groups was significantly decreased(P < 0.05). Conclusion ACR may interfere with the growth and development of neurons by reducing the expression of DCX and GAP-43.

Objective To investigate the role of ceramide in radiation induced bystander effect (RIBE) in vivo by irradiating Caenorhabditis elegans with proton microbeam.Methods The posterior pharynx of wide-type N2 and genetically mutated L4-staged worms was irradiated with 2 000 particles,then germ cell apoptosis and gene expression were analyzed.Results Point-fixed radiation to posterior pharynx of N2 worms significantly increased the number of apoptotic germ cells (t =9.007,P＜0.05),but not in the worms with deletion mutants of ceramide synthase (CerS) genes (hyl-1 and lagr-1) (P＞0.05).Realtime quantitative PCR assay indicated that in both N2 and lagr-1 (gk327);hyl-1 (ok976) worms,the genes of egl-1 and ced-13 in core apoptosis pathway were up-regulated after radiation to posterior pharynx,without statistical significance between these two strains (P＞0.05).The gene expression levels of hyl-1 and lagr-1 were increased in both N2 and hus-1 (op241) worms after radiation with no statistical significant difference between two strains (P＞0.05).Furthermore,radiation-induced germ cell apoptosis was increased in abl-1 (ok171) worms (t=13.241,P＜0.05),rather than in lagr-1(gk327);hyl-1(ok976);abl-1(ok171) worms (t=13.462,P＜0.05).Conclusions Ceramide is required for RIBE on germ cell apoptosis in C.elegans,and it might play function together with egl-1 and ced-13 in core apoptosis pathway and HUS-1 in DNA damage response pathway.But ceramide had antagonistic relationship with anti-apoptotic protein abl-1 in germ cell apoptosis.

Objective To evaluate the prognostic value of anemia in patients diagnosed with extranodal nasal-type natural killer (NK)/T cell lymphoma (NKTCL).Methods Clinical data of 1 225 NKTCL patients receiving the first course of treatment from 10 medical institutions in China were retrospectively analyzed.According to the diagnostic criteria in China,anemia was defined as the hemoglobin (Hb) level＜ 120 g/L for the male and＜ 110 g/L for the female from the sea-level area.The severity of anemia was classified into the extremely severe anemia (Hb ≤ 30 g/L),severe anemia (31-60 g/L),moderate anemia (61-90 g/L) and mild anemia (＞90 g/L).Results Among 1 225 patients,199(16.2％) were complicated with anemia,who had more adverse prognostic factors compared with their counterparts without anemia.Among NKTCL patients with anemia,the proportion of patients with stage Ⅱ-ⅣV,a median age＞ anemia,Eastern Cooperative Oncology Group (ECOG) score of 2-4 and NK/T-cell lymphoma prognostic index (NKTCLPI) ≥ 2 was relatively high.Patients with anemia obtained worse clinical prognosis than those without anemia.The 5-year overall survival (OS) and progression-free survival (PFS) in NKTCL patients with anemia were calculated as 49.4％ and 35.4％,significantly lower compared with 63.3％ and 56.0％ in their counterparts without anemia (both P＜0.01).Single factor analysis demonstrated that anemia,age,ECOG score,group B symptom,lactate dehydrogenase,primary tumor site,primary tumor invasion and staging were the prognostic factors of OS and PFS.Multivariate analysis revealed that anemia was still the independent prognostic factor.Conclusions Anemia is not common in patients with NKTCL and these patients obtain poor clinical prognosis.Anemia is an independent prognostic factor for patients with NKTCL.
