CMV related matrix protein pp65 antigenemia was screened in 100 Allo HSCT patients after transplantation. As control groups, samples from fourteen autologous HSCT patients, seventeen patients with various hematological malignant disorders, as well as twenty seven normal donors also were detected. CMV antigenemia was found in 91/100 Allo HSCT patients (91%) after transplantation. 56 % patients with antigenemia developed CMV disease. 54% patients developed acute GVHD. In 87 patients survived more than three months, 52 9% patients developed chronic GVHD. After follow up 18(4～36) months post transplantation, 21 patients died of CMV related diseases. Compared with autologous and non transplantation patients, CMV antigenemia and CMV diseases were particularly associated with Allo HSCT patients. It was obviously correlated with acute and chronic GVHD. CMV infection is a major factor affecting the clinical outcome of Allo HSCT patients.

Cooling bag for heat stroke in wild field was invented in order to fulfill rapid cooling for heat stroke in field environment. The cooling bag is composed of the hood, the body cover (which is made up of the anterior portion, the linking, and the posterior portion), the fixed straps, the handles. The length is 200 cm, the regulative width is 60-70 cm, the folding volume is 26 cm× 20 cm× 9 cm, and the weight is 1.4 kg. There are a number of pockets for the cold sources in the hood and the body cover. Fixed straps are set in the upper, middle and lower of the bag. The handles are set in the hood and the body covers. Usage: put the activated cold sources in the pockets, then put off the patient's clothes, stretch his/her arms into the linking, zipper up and wrapped up by the fixed straps; the amount of cold sources can be adjusted or changed according to the temperature. The patient's temperature, blood pressure, intravenous infusion can be monitored during the cooling course. The handles in the hood and the body cover allow the patient to be easily moved and be transferred in rescue. The cooling bag for heat stroke in field has good cooling effect, and are reusable and easy to be carried, operate, monitor and move, with low cost, which make it popularization and application.

Objective To study the method,effect and safety of percutaneous targeted argon-helium (cryoablation) for liver cancer. Methods Retrospective analysis of the clinical data was made on the 52 (patients) with primary liver cancer who were treated with argon-helium cryoablation. Results Following the treatment of the 52 (patients), there were no operative mortality or complications, such as rupture of liver,bleeding,biliary fistula,frostbite of skin,and metastatic implantalion or infection at the injection site.(Postoperatively), 5 patients developed pneumothorax and reactive pleural effusion, and 43 patients had a low-grade fever. The 1- and 2-year survival rates were 63.5 %( 33/52) and 36.5 %( 19/52)(respectively).After treatment, the AFP levels were significantly lower. Conclusions CT guided percutaneous targeted argon-helium cryoablation is a reasonable, safe, effcctive and mimimally invasive new therapeutic method for the treatment of liver cancer.

Object To determine and compare the content of polysaccharides in three species of Semen Plantaginis from different places of origin. Methods Spectrophotometry was used. Results The content of polysaccharides in the seed of Plantago major L. was higher than those in the seed of P. asiatica L. and P. depressa Willd. Conclusion The content of polysaccharides in Semen Plantaginis of different species or origins are obviously different.

OBJECTIVETo explore the relationship between a proliferation-inducing ligand (APRIL) expression in primary tumor foci of breast cancer and the patients' prognosis.

METHODSParaffin sections of surgical specimens were retrospectively collected from 130 stage I-III breast cancer patients who received surgery between January 2000 and December 2002 in our hospital. Immunohistochemistry was used to assess APRIL expression intensity in the tumor cells and density of interstitial APRIL-positive cells, and their association was analyzed with the density of interstitial CD4⁺ and CD8⁺ cells and with the histopathologic features, overall survival (OS), and disease-free survival (DFS) of the patients.

RESULTSAPRIL positive staining was found in the cytoplasm of the tumor cells, interstitial cells, and the extracellular matrix. APRIL intensity in the tumor cells was positively correlated with the density of interstitial APRIL-positive cells (P=0.009) and Ki67 (P=0.003). The density of interstitial APRIL-positive cells was positively correlated with the density of interstitial CD4⁺ cells (P<0.001) and CD8⁺ cells (P<0.001). In hormone receptor negative patients (ER- and PR-), multivariate COX regression identified the density of interstitial APRIL-positive cells as a positive prognostic factor for DFS (HR=0.313, 95% CI=0.107-0.920, P=0.035). CONCLUSIONSl APRIL is widely expressed in the interstitial immune cells in breast cancer. APRIL staining intensity in the tumor cells is positively correlated with tumor proliferation, indicating that the immune cells might promote tumor proliferation by secreting APRIL. A greater density of interstitial APRIL-positive cells is associated with a good prognosis in hormone receptor-negative patients.

OBJECTIVETo examine the expression pattern of membrane type-1 matrix metalloproteinase (MT1-MMP) in breast carcinomas.

METHODSForty-three breast cancer tissues were collected and examined for MT1-MMP protein and mRNA expressions using immunohistochemistry, semi-quantitative RT-PCR and in situ hybridization.

RESULTSImmunohistochemistry of the breast cancer specimens showed MT1-MMP immunoreactivity on the cancer cell membrane. MT1-MMP mRNA was located in the stromal cells surrounding the breast cancer nest as shown by in situ hybridization. MT1-MMP mRNA expression was detected in all of the carcinomas, but its level was significantly lower in immunohistochemically negative specimens than in positive ones (0.547=0.0886 vs 0.759=0.0802, Plt;0.01).

CONCLUSIONMT1-MMP is very likely produced by stromal cells surrounding the breast cancer nest and anchored on the cell membrane after activation.

To investigate the significance of GATA-2 and immunoglobulin heavy chain germline gene C( micro ) (IgH germline gene C( micro )) expression and coexpression in various leukemia cells, GATA-2 and IgH germline gene C( micro ) mRNA in bone marrow and peripheral blood cells from 63 leukemia patients were detected by reverse transcription-polymerase chain reaction (RT-PCR). No GATA-2 or IgH germline gene C( micro ) mRNA were detected in normal bone marrow and peripheral blood. GATA-2 mRNA were be detected in 91.3% patients with acute myeloid leukemia (AML), 75% patients with acute lymphoblastic leukemia (ALL) as well as 83.3% patients with chronic myeloid leukemia (CML-CP); IgH germline gene C( micro ) mRNA were be identified in 47.8% AML, 41.6% ALL, as well as 5.6% CML-CP. All patients with CML-AP and CML-BC expressed GATA-2 mRNA and partly expressed IgH germline gene C( micro ) mRNA. 47.8% AML and 41.6% ALL patients coexpressed GATA-2 and IgH germline gene C( micro ) mRNA. GATA-2(+) IgH germline gene C( micro )(+) cells of AML and ALL were mainly HLA-DR positive. As aberration of the transcription factors, GATA-2 and germline IgH germline gene C( micro ) gene might been linked to leukemogenesis. Various expression of GATA-2 and germline IgH germline gene C( micro ) gene in leukemia might correlated with the heterogeneous differentiation level of leukemia cells. The fact that leukemia with GATA-2(+) IgH germline gene C( micro )(+) coexpression indicated multilineage impairment of hematopoietic cells.

Objective To evaluate the applied value of septal cartilage combined with perpendicular plate of ethmoid bone graft in short nose plasty in Chinese people with insufficient septal cartilage.Methods From February 2015 to March 2017,thirty-five women with short noses underwent septal extension grafting in our institute.We used perpendicular plate of ethmoid bone to enhance the L-strut structure.An L-strut,comprising 0.6 cm segments of the caudal and dorsal cartilaginous septum,was left altered to harvest more cartilages for septal extension.The harvested septal cartilage was grafted on one side of the caudal septum.Then the alar cartilage was fixed at the end of the septal cartilage graft.Nasal lengths and nasolabial angles were measured pre-and postoperatively.Results The average nasal lengthening was (3.37±1.87) mm (P＜0.001).There was no infection,cerebral spinal fluid leakage,hemorrhage and other complications postoperatively.The average follow-up was 10 months (6 months to 2 years).After operation,33 patients were satisfied with the nasal contour,1 patient complained of high tip projection whereas one patient complained of low tip projection,and the dissatisfactions were corrected by revision surgeries.Conclusions Combining the septal cartilage with perpendicular plate of ethmoid bone graft presents an adequate nose lengthening and a decreased nostril show,even in patients with very little septal cartilage.With minimum complications,this novel technique provides promising clinical outcomes and high patient satisfaction.

OBJECTIVETo screen differentially expressed genes and identify potential signaling pathway in Asian people with breast cancer.

METHODSFive gene microarray datasets of Asian people with breast cancer, GSE6367, GSE9309, GSE15852, GSE33447 and GSE45255, were downloaded from GEO. Microarrays with 318 breast cancer and 60 normal breast tissues were used for analysis of differentially expressed genes and pathway. 32 pairs of breast cancer patients' specimens were used to validate the differentially expressed genes by real-time PCR.

RESULTSAnalysis of the large sample of microarray data identified 436 differentially expressed genes in breast cancer tissues, while 259 of these genes were up-regulated and the other 177 down-regulated. Pathway analysis showed that metabolism-related signaling pathway may be involved in the development of breast cancer in Asian people. The expressions of KRT19, ADIPOQ, CFD, RBP4, LPL, ABCA8 and CD36 genes were confirmed by real-time PCR.

CONCLUSIONThis study shows differential gene expression profile and potential signaling pathway in Asian people with breast cancer. CD36 gene may be closely related to the Asian breast cancer. ABCA8 gene may be a new disease gene in Asian breast cancer.

BACKGROUND: Lung cancer prevails and induces high mortality around the world. This study provided real-world information on the evolution of clinicopathological profiles and survival outcomes of lung cancer, and provided survival information within stage I subtypes. METHODS: Patients pathologically confirmed with lung cancer between January 2009 and December 2018 were identified with complete clinicopathological information, molecular testing results, and follow-up data. Shifts in clinical characteristics were evaluated using χ2 tests. Overall survival (OS) was calculated through the Kaplan-Meier method. RESULTS: A total of 26,226 eligible lung cancer patients were included, among whom 62.55% were male and 52.89% were smokers. Non-smokers and elderly patients took increasingly larger proportions in the whole patient population. The proportion of adenocarcinoma increased from 51.63% to 71.80%, while that of squamous carcinoma decreased from 28.43% to 17.60%. Gene mutations including EGFR (52.14%), KRAS (12.14%), and ALK (8.12%) were observed. Female, younger, non-smoking, adenocarcinoma patients and those with mutated EGFR had better survival prognoses. Importantly, this study validated that early detection of early-stage lung cancer patients had contributed to pronounced survival benefits during the decade. Patients with stage I lung cancer, accounted for an increasingly considerable proportion, increasing from 15.28% to 40.25%, coinciding with the surgery rate increasing from 38.14% to 54.25%. Overall, period survival analyses found that 42.69% of patients survived 5 years, and stage I patients had a 5-year OS of 84.20%. Compared with that in 2009-2013, the prognosis of stage I patients in 2014-2018 was dramatically better, with 5-year OS increasing from 73.26% to 87.68%. Regarding the specific survival benefits among stage I patients, the 5-year survival rates were 95.28%, 93.25%, 82.08%, and 74.50% for stage IA1, IA2, IA3, and IB, respectively, far more promising than previous reports. CONCLUSIONS Crucial clinical and pathological changes have been observed in the past decade. Notably, the increased incidence of stage I lung cancer coincided with an improved prognosis, indicating actual benefits of early detection and management of lung cancer.
