1.The preliminary exploration into regulating sub-health as preventive and therapeutic strategies for tumor.
Chinese Journal of Integrated Traditional and Western Medicine 2012;32(3):412-414
The definition of sub-health was studied from the angle of tumor dormancy again. We believe it is necessary to further supplement the present definition, diagnosis criteria, and assessment means. The definition of sub-disease and the division of a disease into four development stages (health --> sub-health --> sub-disease --> disease) were also brought up. Furthermore, we believe that application of regulating sub-health as preventive and therapeutic strategies for tumor is an anti-cancer method with Chinese features, which enriches the modern theories of tumor prevention and therapy.

To explore differentially expressed genes in leukemia gene expression profile and identify main related genes in acute leukemia, gene expression profiles were analyzed in bone marrow/leucopheresis peripheral blood stem cells samples from 9 acute leukemia patients and their sibling donors with the use of oligonucleotide microarrays. 163 reported leukemia-related genes were involved in the study. The oligonucleotide primers were designed, synthesized and spotted on the chemical-material-coated-glass plates in array. The total RNAs were isolated from nine patients' bone marrow or leucopheresis peripheral blood cells and from nine their sibling donors peripheral blood stem cells treated by G-CSF, then collected by CS-3000 cell selection machine, and were reversely transcribed to cDNAs with the incorporations of fluorescent dUTP. The mixed probes were then hybridized to the oligonucleotide microarray. The results showed that in four patient/donor pairs with B-ALL, 5 up-regulated (RIZ, STK-1, T-cell leukemia/lymphoma 1A, Cbp/p300, Op18) and 1 down-regulated genes (hematopoietic proteoglycan core protein) were identified; In five patient/donor pairs with AML-M(4) and AML-M(5), 6 up-regulated (STAT5B, ligand p62 for the Lck SH2, CST3, LTC4S, myeloid leukemia factor 2 and epb72) and 1 down-regulated genes (CCR5) were identified. In conclusion, on the basis of distinguishing study of specific genetic related recipient/sibling donor pairs, screening leukemia-related genes with oligonucleotide microarrays, a set of 13 up-regulated or down-regulated genes among 163 leukemia-related genes has been identified. The result has further confirmed that above genes play critical role in the molecular mechanism of acute leukemia.

ObjectiveTo investigate the clinicopathological features and prognosis of natural killer (NK)/T cell lymphoma and to analyze its relationship with Epstein-barr virus(EBV). MethodsTotally, 36 cases of cutaneous NK/T cell lymphoma were collected from 2000 to 2010 at the Department of Pathology, Peking University Health Science Center, and classified into primary and secondary groups according to whether there is evidence of extracutaneous involvement within 6 months after diagnosis. Clinicopathological features were analyzed and Epstein-barr virus (EBV) was detected. ResultsOf these 36 cases, 13 (36.1%) were classified as primary cutaneous NK/T cell lymphoma, 20 (55.6%) as secondary, and 3 (8.3%) remained unclassified because of the lack of clinical data. Males were more likely to develop both primary and secondary cutaneous NK/T cell lymphoma than females, but there was no striking difference in sex ratio between the patients with primary and secondary lymphoma (P > 0.05 ). Compared with the patients with primary cutaneous NK/T cell lymphoma, those with secondary cutaneous NK/T cell lymphoma showed a younger median age at onset(43.5 vs. 54 years, P < 0.05), higher prevalence of B symptoms(including fever, night sweat, body weight loss) and multiple skin lesions (P < 0.05 and 0.01, respectively). EBV was positive in 92.3% (12/13) of the primary lymphoma cases and 85%(17/20) of the secondary lymphoma cases. Moreover, the median survival was 8 months in all the cutaneous NK/T cell lymphoma cases, and was significantly shorter in secondary cases than in the primary cases(6 vs. 18 months, x2 = 6.074, P < 0.05). ConclusionsCutaneous NK/T cell lymphoma is an EBV-associated, clinica]ly aggressive disease entity. Patients with primary cutaneous NI/T cell lymphoma seem to have an older age at onset and a better prognosis as compared with those with secondary cutaneous NK/T cell lymphoma.

OBJECTIVETo evaluate the efficacy of Bufei Yishen Granule BFYSG) combined with Shufei Tie acupoint sticking therapy on quality of life of patients with stable chronic obstructive pulmonary disease (COPD).
METHODSA multi-center, double-blinded, double-dummy and randomized controlled method was adopted in this trial. A total of 244 patients were randomly assigned to a trial group and a control group according to the random number, each with 122 patients; treatment allocation occurred when the participants met the inclusion criteria and signed the informed consent form. In the trial group, patients were treated with BFYSG combined with "Shufei Tie" acupoint sticking therapy and sustained-release theophylline dummy, and in the control group patients were treated with oral sustained-release theophylline and BFYSG dummy combined with "Shufei Tie" acupoint sticking therapy dummy. The therapeutic course for two groups was 4 months and the follow-up was 6 months. The frequency and duration of acute exacerbation calculated by adding up each frequency and duration of acute exacerbation in treatment and follow-up time respectively, the quality of life measured by the World Health Organization Quality of Life (WHOQOL)-BREF scale and adult COPD quality of life (COPD-QOL) scale were observed.
RESULTSAmong the 244 enrolled patients, 234 were screened for full analysis set (FAS); 221 were screened for per-protocol analysis set (PPS). After 4-month treatment and 6-month follow-up there were differences between the trial group and the control group in frequency of acute exacerbation (FAS: P=0.013; PPS: P=0.046); duration of acute exacerbation (FAS: P=0.005; PPS: P=0.006); scores of physiological, psychological and environment aspects of the WHOQOL-BREF questionnaire (FAS: P=0.002, P=0.006, P=0.000; PPS: P=0.00, P=0.001, P=0.000); scores of daily living ability, social activity, depression symptoms aspects of the COPD-QOL questionnaire (FAS: P=0.000, P=0.000, P=0.006; PPS: P=0.002, P=0.001, P=0.001).
CONCLUSIONBFYSG combined with acupoint sticking therapy could improve the quality of life of patients with stable COPD.

OBJECTIVETo explore the effect of one dressing of porcine acellular dermal matrix on deep partial thickness burns.
METHODSFrom January 1997 to January 2004, sixty-seven cases of deep partial thickness total burned surface area (TBSA) from 50% to 90% burn wound were treated by a single dressing of porcine acellular dermal matrix (the porcine acellular dermal matrix group). Ten cases of deep partial thickness burned patients with the same TBSA treated by exposure method served as the exposure method group. The healing time of the wound was observed. The patients were followed up for 3 months to 2 years, and the scar proliferation was observed.
RESULTSThe deep partial-thickness wound would be healed without dressing change in the porcine acellular dermal matrix group, and the average healing time was (12.2 +/- 2.6) days. The average healing time of the exposure method group was (27.4 +/- 3.5) days. Follow up of the patients within 3 months to 2 years showed that scar proliferation in the porcine acellular dermal matrix group was much less than that in the exposure method group, even no scar proliferation was observed in some patients.
CONCLUSIONWithout tangential excision, autografting and dressing change, a single dressing of porcine acellular dermal matrix on deep partial thickness burn wound could shorten the healing time and inhibit scar proliferation.

OBJECTIVETo investigate the role of xenogenic (porcine) ADM as dermal substitute in scar treatment.
METHODSAfter scar excision, the wounds were covered with composite grafts of DR procine ADM and autologous thin split-thickness grafts in one stage or in two stages.
RESULTS22 out of 47 cases were treated in two-staged procedure. After the ADMs were applied to the wound, the autologous thin split-thickness grafts were implanted 7 days later. 25 cases were treated in one-staged procedure. The survival rates of composite grafts were (88.3 +/- 3.7)% for subcutaneous recipient bed and (89.7 +/- 3.4)% for deep fascia recipient bed in group with two-staged procedure, compared with (92.5 +/- 4.1)% and (93.2 +/- 5.2)%, respectively, in group with one-staged procedure. Early after grafts taken, the grafts had a pink colour and smooth surface. The patients were followed up for 90 days at most. The survived composite grafts were durable, elastic, smooth and soft with good function and appearance like normal skin. They could even be pinched up. The scar along the edge of the grafts was slightly hypertrophic.
CONCLUSIONSThe survival rate of composite graft is higher in patients with one-staged procedure. The elasticity and textural of the taken grafts are better on subcutaneous recipient bed than on deep fascia recipient bed, though the function has no difference. Xenogenic (porcine) ADM can be an optimal dermal substitute for wound coverage after scar excision.

OBJECTIVETo study the prognostic implications of hematopoietic cell transplantation-specific comorbidity index (HCT-CI) on non-relapse mortality (NRM) and overall survival (OS) in patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODSClinical data of 161 cases received allo-HSCT from July 2003 to November 2010 were analyzed retrospectively. The prognostic significance of HCT-CI, age, sex, conditioning regimens, disease status before transplantation, graft source and the degree of HLA matches for NRM and OS was conducted by COX regression model. The prognostic impact of HCT-CI on NRM and OS was performed in all patients under different disease status before transplantation.
RESULTSOf the 161 cases with allo-HSCT, 3-year NRM and OS were 26.4% and 61.4% respectively. NRM at 3 years in patients with HCT-CI score 0, 1-2 and ≥3 were 14.9%, 24.5% and 52.7% respectively. And OS at 3 years were 68.9%, 64.6% and 34.7% respectively. There were significant differences between HCT-CI score 0 and ≥3 groups for NRM and OS (P<0.01). High-risk disease status before transplantation (NRM: RR=3.35, P<0.01;OS: RR=3.53, P<0.01) and HCT-CI score≥3 (NRM: RR=6.85, P<0.01;OS: RR=3.77, P<0.01)were independent risk factors by COX regression model. In the subgroup analysis according to disease status, high score of HCT-CI was associated with poor OS (P<0.01) and high NRM (P<0.01) in patients with low-risk, but not in those with high-risk disease status.
CONCLUSIONHCT-CI score and disease status before transplantation are independent risk factors for patients received allo-HSCT. HCT-CI score have prognostic implication for NRM and OS in patients with low-risk disease status, but not in high-risk group.

The aim of this study was to evaluate the application value of SPECT/PET (18)F-FDG imaging in patients with lymphoma and its significance in monitoring relapse of this disease. A retrospective analysis of 71 SPECT/PET examinations was performed in patients with lymphoma diagnosed by pathologic and immunohistochemistry means from 1998 to 2008 in Peking university first hospital. The results showed that 28 patients underwent SPECT/PET before initial therapy, the accuracy of SPECT/PET and CT were 100% and 81.7% respectively. The diagnostic sensitivity of SPECT/PET and CT for foci were 85.7% and 53.5% respectively, and there was significant difference between them (p = 0.003). The diagnostic sensitivity of SPECT/PET and CT for extranodal foci were 91.3% and 56.5% respectively, there was significant difference also between them (p = 0.007). 32 patients underwent 43 SPECT/PET for monitoring relapse during follow up. The positive predictive value and negative predictive value of SPECT/PET for relapse were 100% and 92.9% respectively. The relapse were found by SPECT/PET in 6 patients more early than appearance of clinical symptoms and physical signs as well as laboratory examination, imaging examination. In conclusion, SPECT/PET has significant value in diagnosing and monitoring relapse for patients with lymphoma.

This study was purposed to investigate the role of NK-alloreactivity and donor-inhibiting or activating KIR gene in predicting prognosis under unmanipulated allogeneic blood and marrow transplantation. A modified polymerase chain reaction sequence specific primers (PCR-SSP) method was used to typing KIR and HLA genotype of donors and recipients. The relationship between donor activating or inhibitory KIR and recipient HLA genotypes on event free survival (EFS), cumulative incidence of malignant relapse and transplant-related mortality (TRM) were investigated retrospectively in 67 patients undergoing hematopoietic stem cell transplantation. The results showed that no effect of 'KIR/HLA mismatched' was detected on acute graft-versus-host disease (aGVHD) and relapse. The EFS of KIR/HLA mismatched group was lower, especially KIR2DL1/HLA-C2 mismatched group (44.8% vs 69.2%, P = 0.043). However, EFS was better for the presence of donor-activating KIR2DS2 (81.3% vs 52.6%, P = 0.052), and the relapse rate was significantly lower for the presence of this genotype (7.7% vs 34.2%, P = 0.05). EFS was worse in patients homozygous for group 1 HLA-C (C1) when donor carries the activating KIR2DS1 (KIR2DS1 positive/HLA-C2-negative group, P = 0.028), and the incidence of aGVHD in this group was significantly higher than that in any other groups (P = 0.028). In multivariate analysis, advanced disease stage, more than two donor-activating KIR, donor KIR2DS2-negative genotype were associated with an reduced disease-free survival (HR = 3.34, 2.19, 3.18;and P = 0.005, 0.053, 0.066). Donor KIR2DS2-negative genotype were also associated with an increased risk of relapse (HR = 6.72, 9.43; and P = 0.019, 0.047). And donor KIR2DS1 positive/recipient HLA-C2 negative group was the only risk factor of TRM (HR = 3.27, 95% CI 1.78 - 9.06, P = 0.023). It is concluded that missing ligand for the donor inhibitory KIR has weak effect on the outcome of unmanipulated HSCT. The activating KIR play an important role in the EFS, relapse and TRM after HSCT. Donor KIR2DS1-positive/recipient HLA-C2-negative group and donor KIR2DS1 gene negative predict poor prognosis. Analysis of KIR genotype and its ligand is important for the selection of best donor and prognostic evaluation in unmanipulated allogeneic HSCT.
