Objective To study the DSA hepatoarteriography manifestations in hepatic carcinoma after endocare cryocare system (ECS)treatment for improving the comprehensive therapy of hepatic carcinoma.Methods Thirty eight male patients with primary liver cancer ( n =32) and hepatic metastasis (n=6) were enrolled in this study. Common hepatic arteriography or super-selection angiography was performed in all patients after ECS treatment in 7 days and 30-60 days.Results The foci covered with ice ball were shown as round or ovoid. Single tumor less than 5 cm was covered completely, while the shape of focus covered with more ice ball showed irregularity, mass-like and diffuse nodulss with diseminated tumor vessels and tumor stains. The shortcoming of ECS included 18 missed areas, hepatic A-V shunt and hepatic A-portal V shunt in 4, bleeding in puncture tract 5, and extravasation of contrast material in 6 cases. Delineated margin existed between the frozon area and surrounding tissues.Conclusions ①ECS is effective on liver tumor 5 cm. ③ Tendency of missed areas in huge tumor and widespread nodes accurs after ECS. ④Complication occurs easily during ECS performance near the hepatic capsule and porta hepatis. ⑤TACE would improve comprehensive therapy effect of liver cancer about7 days after cryotherapy.

OBJECTIVETo study the molecular epidemiological characteristics of hantavirus seen during 2000-2003 in Qingdao region of Shandong province.

METHODSSera were collected from 64 patients with hemorrhagic fever with renal syndrome (HFRS) and viral RNA was extracted from the sera. HTN and SEO universal primers were designed as outer primers and HTN and SEO specific primers as inner primers. G1 gene region of M segment from hantavirus was amplified by using RT-nest-PCR for sequencing. The data of nucleotide sequences were analyzed by DNA star software.

RESULTSSix cases were positive by HTN specific primer of total cases (9%); 25 of 64 cases by SEO specific primer (39%); total positive rate was 48%. In general, SEO type was a prevalent type of hantavirus in Qingdao region. The variation of the nucleotide sequences among SEO viruses (nucleotide sequence divergence ranged from 0.3% approximately 8.9%) was lower than that among HTN type (nucleotide sequence divergence ranged from 2.6% approximately 11.2% ).

CONCLUSIONMajority of hantavirus found in Qingdao region belonged to SEO type and still a few strains belonged to HTN type. Most of the HTN viruses were detected in Jiaonan county.

Objective To study the clinical characteristic of acquired immune deficiency syndrome (AIDS) patients younger than 15 years old and to explore the influence of human immunodeficiency virus (HIV) infection on them. Methods The clinical information, including demographic profile, clinical stages of the disease, laboratory test results and developmental status were gathered from 275 antiretroviral therapy naive patients. Results Seventy eight point nine percent patients were infected by vertical transmission. Sixteen percent were infected by receiving blood products. The average age was (7.6±3. 7) years, with 5 cases younger than 1 year old, 104 cases ranging from 1 - 5 years and 166 cases elder than 6 years. Seventy point one percent patients were classified as stage 3 or 4 according to World Health Organization definitions. The average CD4 count was ( 137 ± 159 )/μL, ( 304 ± 317 ) /μL and ( 1 246 ± 776 )/μL respectively in children elder than 6 years, ranging from 1 to 5 years and younger than 1 year. One hundred and eighty one cases suffered from anemia on different severity grading. The most common HIV related symdromes included persistent fever, skin damage, persistent diarrhea, oral candidiasis and recurrent upper respiratory tract infection. Among these infected children, 49. 6% showed height lower than x - 2s and 19. 9% showed weight lower than x - 2s. Conclusions Most survival pediatric AIDS patients are elder than 6 years. HIV infection can significantly affect the children's immune system function,growth and development.

OBJECTIVETo investigate the risk factors of intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSThe clinical data of 534 cases of 533 patients undergoing allo-HSCT during Jan 2004 and Sep 2012 were retrospectively analyzed. The effects of donor-recipient HLA mismatching, recipient age, donor age, donor-recipient sex combination, donor-recipient relationship, HSC source, conditioning regimen with or without total body irradiation (TBI) and HLA loci on intestinal aGVHD with different severity were analyzed by Logistic regression.

RESULTSIntestinal aGVHD occurred in 123(23.0%) cases, with 86(16.1%) cases of stage 1 intestinal aGVHD(16.1%) and 37(6.9%) cases of stage 2 to 4 intestinal aGVHD. Multivariate analysis showed that donor-recipient HLA mismatching (OR=2.519, P=0.002), increasing donor age (OR=1.034, P=0.003), female donor for male recipient (OR=1.855, P=0.007) were risk factors for intestinal aGVHD, HLA-B38 (OR=0.256, P=0.032) was its protective factor. Donor-recipient HLA mismatching (OR=2.799, P=0.011), increasing donor age (OR=1.045, P=0.012), HLA-A1 (OR=4.157, P=0.002), A30 (OR=3.143, P=0.005) were risk factors for stage 2 to 4 intestinal aGVHD.

CONCLUSIONOccurrence of intestinal aGVHD and its severity are associated with donor-recipient HLA mismatching, donor age, donor-recipient sex relationships and some HLA loci.

Objective To investigate the curative effects of various infusion volumes on liver-related metabolic mechanism in the treatment of hemorrhagic shock.Methods A severe hemorrhagic shock rabbit model was established in 30 rabbits.The rabbits were randomly divided into three groups:non-infusion group (A), conventional infusion group (B), and excessive infusion group (C) (n=10 in each group).Taking group B as the control, groups A and C were observed for the damage of non-infusion and excessive infusion, respectively.The outcomes in the three groups and their relations with liver tissue metabolism changes were analyzed with gas chromatograph-mass spectrometer (GC-MS).Results The mortality in groups A, B, and C group were 80％, 0％, and 70％, respectively.The liver tissue metabolic profile in group B showed statistically significant difference compared with that in groups A and B.In group C, the levels of 21 metabolites were lower than those in group B, and the levels of8 metabolites were lower than those in group A.The relative contents of various metabolites were correlated with infusion volumes, and the succinic acid content was associated with death events (P＜0.05).Conclusion The conventional infusion has significant curative effect on hemorrhagic shock.The metabolites of liver tissues with excessive infusion are generally decompensated and have longer survival time than those in non-infusion group, which may caused by the excessive infusion-induced blood volume increase after hemorrhagic shock.Tissue fluid dilution is an important cause of death.

BACKGROUND: The tumor necrosis factor recepter associated factor (TRAF) 6 is an important intracellular adapter protein that plays a pivotal role in activating multiple inflammatory and immune related processes induced by cytokines. TRAF6 represents a strong candidate susceptibility factor for sepsis. We investigated whether polymorphisms at the TRAF6 gene are associated with the susceptibility to and severity of sepsis. METHODS: A hospital-based case-control study was conducted with 255 patients with sepsis and 260 controls who were recruited from Zhengzhou, China. Haplotype tagging single nucleotide polymorphisms (htSNPs) were selected from the HapMap database and genotyped using the SNPstream genotyping platform. The associations with the susceptibility and disease severity of sepsis were estimated by logistic regression, and adjusted for age, sex, smoking, drinking, chronic diseases status, APACHEII score and critical illness status. RESULTS: A total of 13 TRAF6 SNPs were tagged by 7 htSNPs. Five htSNPs (rs5030490, rs5030411, rs5030416, rs5030445 and rs3740961) were genotyped in the case control study. Genotype frequencies of the htSNPs were conformed to the Hardy-Weinberg equilibrium in both patients and controls. No significant association was found between the 5 htSNPs and the susceptibility to and severity of sepsis. Compared with the main haplotype -11120A/-10688T/-9423A/805G/12967G, no certain haplotype was associated with the significantly susceptibility to or severity of sepsis. CONCLUSION: TRAF6 gene polymorphisms might not play a major role in mediating the susceptibility to and severity of sepsis in the Chinese population. A larger population-based case-control study is warranted.

OBJECTIVETo investigate the incidence, risk factors, prognosis and high risk patients of invasive fungal infections (IFI) in patients with hematological diseases.

METHODS: Over 2-week hospitalized patients from January 2007 to December 2008 were retrospectively reviewed. Logistic regression was used to analyze the risk factors of IFI, and recursive partitioning to reveal high risk patients. Incidence of IFI was estimated by cumulative incidence function, and the prognosis by Kaplan-Meier method.

RESULTSA total of 1048 assessable treatment cycles were recorded and 93 cases of IFI were diagnosed, with an incidence of 8.87 per 100 treatment cycles. Multivariate logistic regression revealed the following risk factors: age (OR 1.025, 95% CI 1.010-1.041, P = 0.002), duration of neutropenia (OR 1.028, 95% CI 1.014-1.042, P < 0.0001) and uncontrolled underlying diseases (OR 2.620, 95% CI 1.608-4.268, P = 0.0001). Recursive partitioning found two groups of high risk patients: (1) patients with uncontrolled underlying diseases and neutropenia duration > or = 58 days (7/12, 58.3%), (2) patients with uncontrolled underlying diseases and age > or = 33 years (40/208, 19.2%). At the end of follow-up, 111 cases of IFI were recorded in 451 patients, with a 1-year cumulative incidence of 27.1%. In patients with established IFI, overall survival rate and IFI related mortality rate at 12 weeks after diagnosis were 83.4% and 13.5% respectively.

CONCLUSIONAge, duration of neutropenia and uncontrolled underlying diseases are risk factors of IFI; patients with uncontrolled underlying diseases and age > or = 33 years were at high risk of IFI and need major concern. IFI has a better prognosis and a lower related mortality in this study.

OBJECTIVETo observe the impacts of different time of moxibustion on its regulating lipid effects and safety of hyperlipidemia.

METHODSSeventy-six cases of hyperlipidemia patients were randomly divided into three groups: including moxibustion 10 min group (group A, 25 cases), moxibustion 20 min group (group B, 25 cases) and moxibustion 30 min group (group C, 26 cases). All of these three groups choose the same acupoints, Shenque (CV 8),Zusanli (ST 36), Fenglong (ST 40) and Sanyinjiao (SP 6) were selected. These three groups were treated with moxibustion for 10 min, 20 min and 30 min, respectively, three times a week, 12 times constituted one course, two courses were required for each group. All indices of blood lipid and fasting blood glucose were observed before and after treatment, and the preliminary evaluation was made on the safety of hepatic and renal function.

RESULTSThere were significant decrease in total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), and blood sugar after moxibustion treatment (all P<0.001), there was no significant difference of high density lipoprotein cholesterol (HDL-C) before and after treatment (P>0.05). The group C played more prominent role than group A in regulating the TC (P<0.01) and LDL-C (P<0.05), there was no significant difference between group C and group B (P>0.05). The blood urea nitrogen(BUN) was significantly reduced after moxibustion treatment (P<0.05), and there were no significant differences of other safety indices before and after treatment (all P>0.05).

CONCLUSIONMoxibustion can effectively and safely reduce the blood lipid level of hyperlipidemia patients, the decreasing degree of lipid is different with different time of moxibustion after treatment, and the decreasing degree in moxibustion 30 min group is significantly better than that in moxibustion 10 min group.

Objective:To observe the improving effect of Danggui Shaoyaosan on diminished ovarian reserve （DOR） in rats triggered by Tripterygia wilfordii polyglycoside tablet combined with stress， and to explore the role of transforming growth factor-β₁ （TGF-β₁）/Smads signaling pathway in such improvement. Method:Forty-eight female SD rats with normal sexual cycle were selected and randomly divided into a normal group （n=8） and a modeling group （n=40）， and the ones in the modeling group were given Tripterygium wilfordii polyglycoside tablets （50 mg·kg^-1） combined with random stress for 15 d. After successful modeling， the rats were randomized into the model group， low-， medium-， and high-dose （3.96， 7.92， 15.84 g·kg^-1） Danggui Shaoyaosan groups， and estradiol valerate group （0.09 mg·kg^-1）， with eight in each group. Under the premise of stress exposure， they were separately gavaged with the normal saline， low-， medium- and high-dose Danggui Shaoyaosan， and estradiol valerate for 15 successive days. The estrous cycle of rats in each group was observed daily. After intervention， the rats were sacrificed and the ovarian visceral index was calculated. The pathological changes in ovarian tissues were observed by hematoxylin eosin （HE） staining. The protein expression levels of TGF-β₁ and TGF-β₁ receptor （TGF-β₁R） in the ovarian tissues of rats were measured by immunohistochemistry （IHC）， and the mRNA expression levels of Smad2， Smad3， and Smad7 in the ovarian tissues by real-time polymerase chain reaction （Real-time PCR）. Result:Compared with the normal group， the model group exhibited disordered estrus cycle （P<0.05）， reduced visceral index （P<0.01）， and down-regulated TGF-β₁ and TGF-β₁R protein and Smad2 and Smad3 mRNA expression in the ovarian tissues （P<0.01）， and up-regulated Smad7 mRNA expression （P<0.01）. Compared with the model group， Danggui Shaoyaosan at the low， medium， and high doses and estradiol valerate improved the estrus cycle of rats to varying degrees （P<0.05） and increased the visceral index， with better effects observed in the medium-group and high-dose Danggui Shaoyaosan groups （P<0.05，P<0.01）. Besides， the protein expression levels of TGF-β₁ and TGF-β₁R and the mRNA expression levels of Smad2 and Smad3 in the ovarian tissues were elevated to varying degrees （P<0.01）， and the Smad7 mRNA expression declined （P<0.01）. The improvements in TGF-β₁ and TGF-β₁R protein expression of the medium-dose Danggui Shaoyaosan group and estradiol valerate group were more obvious. Conclusion:Danggui Shaoyaosan significantly improves ovarian reserve in DOR rats， which is closely related to the regulation of TGF-β₁/Smads signaling pathway.

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.
