OBJECTIVETo establish a solvent desorption Gas chromatographic method for detecting the isoflurane in air of workplaces.

METHODSThis method is based on "Standardization of methods for determination of toxic substances in workplace air".

RESULTSThis method presents the linear relation with the minimum detectable limit 1.0 µg/ml and the minimum detectable concentration 0.07 mg/m(3). The precision (RSD) was 0.5% ∼ 5.0%, the mean dsorption efficiencies were 96.7% ∼ 98.9%, the absorption efficiencies were 92.1% ∼ 100%, the breakthrough volume was 3.7 mg isoflurane/100 mg active carbon. Other volatile organic solvents (Sevoflurane, Enflurane and Ethyl Alcohol) did not interfere the detection. The sample could be stored in the active carbon tube at least for 10 days.

CONCLUSIONThis method is meet the requirement of GBZ/T 210.4-2008 "Guide for establishing occupational health standards-Part4: Determination methods of air chemicals in workplace" and is feasible for determining the isoflurane in the air of workplaces.

The aim of the present study is to investigate the expression of a novel estrogen receptor, G protein-coupled receptor 30 (GPR30) and its correlation with matrix metalloproteinases-9 (MMP-9) in epithelial ovarian cancer (EOC). Ovary tissues were obtained from 39 female patients, including 30 cases of EOC and 9 cases of benign ovarian tumor. Four normal ovary tissues were used as control. Immunohistochemical staining was used to detect the expressions of GPR30 and MMP-9. Chi square test, Fisher's exact test and Spearman's rank correlation analysis were used for statistical analysis. The results showed that GPR30 overexpression rate in EOC cases was significantly higher than those in benign ovarian tumor and normal ovary cases. Whereas MMP-9 overexpression rate in EOC cases was significantly higher than that in normal ovary cases, without any difference to that in benign ovarian tumor cases. To demonstrate the relationship between GPR30 and clinicopathological variables of EOC, we further analyzed the pathology type, FIGO stage and age of patients sampled in our study. The analysis showed there were significant differences of GPR30 overexpression rate among various pathology types and different FIGO stages (P<0.05), and no significant difference of both GPR30 and MMP-9 among three age groups (P>0.05). Moreover, GPR30 expression was positively correlated with MMP-9 (r(s)=1.000, P=0.002). These results suggest that GPR30 may be involved in the invasion and metastasis of EOC, being a potential index of EOC early diagnosis and malignancy grade prediction.

OBJECTIVETo study the epidemiologic characteristics of virus-induced acute diarrhea in children under 5 years old in Taiyuan, Shanxi province.

METHODSStool specimens and clinical data were collected from 346 inpatients with acute diarrhea from children less than 5 years old. Rotavirus-positive specimens were identified by ELASA kit. Calicivirus and astrovirus were detected by reverse transcription-polymerase chain reaction (RT-PCR). Adenovirus was done by polymerase chain reaction (PCR).

RESULTSOf the 346 specimens, the percentage of samples with Rotavirus, Calicivirus, Astrovirus, and Adenovirus was 40.8%, 7.5%, 6.4% and 3.2%. Among 141 rotavirus positive samples, serotype G1 (42.6%) was the predominant strain. More than 95% of viral diarrhea patients under hospitalization occurred among children younger than 2 years.

CONCLUSIONRotavirus is the major pathogen contributing to the acute diarrhea. The disease generally peaks at autumn/winter. The predominant rotavirus strain circulated was G1P[8].

OBJECTIVETo compare the enlarged mesenteric lymph nodes in healthy children with those children with mesenteric lymphadenitis.

METHODSAccording to the diagnostic criteria defining lymph node enlargement as a 5-mm enlargement or greater in the short diameter, 137 healthy children and 148 children with mesenteric lymphadenitis were retrospectively analyzed for mesenteric lymph node enlargement based on the ultrasonographic data.

RESULTSThe distribution of enlarged mesenteric lymph nodes was detected in the right lower quadrant (RLQ) in 46.3%, in the para-aortic areas in 19.2%, and in the left lower quadrant (LLQ) in 13.6% of the children. The clusters of lymph nodes between the two groups showed no significant difference in the distribution, age, L/W, longitudinal diameter or clusters, only the short diameter differed significantly between them.

CONCLUSIONEnlarged mesenteric lymph nodes are present in many healthy children, which does not necessarily suggests any abnormalities. The mesenteric lymph nodes increase with the age until 6 years and then decrease. The lymph nodes with a short diameter larger than 8 mm may indicate the condition of mesenteric lymphadenitis.

OBJECTIVETo investigate the effect of HLA-Cw on haploidentical hematopoietic stem cell transplantation (HHSCT) without T-cell depletion.

METHODSHLA-Cw were detected with PCR-SSP, the clinical data of 21 cases of haploidentical hematopoietic stem cell transplantation, including 8 standard risk and 13 high risk cases from July 2002 to March 2006 were summarized, and the effect of HLA-Cw in HHSCT was analyzed.

RESULTSTwenty patients achieved sustained, full-donor-type engraftment. The HLA-Cw matched and mismatched groups attained neutrophil recovery at a median of 12 days and 13 days, and platelet recovery to more than 20 x 10(9)/L at a median of 20 days and 23 days respectively (P > 0.05). The cumulative incidences of grades II-IV acute GVHD were 76.9% in HLA-Cw matched group and 14.3% in the mismatched group(P < 0.05). The incidences of chronic GVHD were 85.7% in HLA-Cw matched group and 57.1% in the mismatched group(P > 0.05). The 28 months disease-free survival probabilities were 49.0% in HLA-Cw matched group, and 85.7% in the mismatched group (P > 0.05). The Karnofsky score of survival patients was over 90%.

CONCLUSIONHLA-Cw mismatched in donor and recipient of HHSCT is beneficial for reducing II-IV aGVHD, and being in favor of long term survival.

OBJECTIVETo study the microsatellite abnormalities of the aromatic amine exposure-associated transitional cell carcinoma (TCC) and sporadic TCC of urinary bladder, and to evaluate the potential of microsatellite analysis on detection of this diseases.

METHODSBased on our previous investigations, 5 microsatellite markers (D17S695, D9S162, D3S1295, DBH and D3S1234) that had high frequencies of loss of heterozygosity (LOH) in sporadic TCC, were selected for analysis with the bladder lesions derived from 16 patients with aromatic amine exposure history. The microsatellite analysis with urine sediments from the post-operated patients was also carried out.

RESULTSThere was at least one informative marker out of the 5 microsatellite foci showed polymorphism in the DNA derived from 16 patients examined. Within 87.50% (14/16) patients, LOH was detected in the bladder lesions at least with one microsatellite marker. The LOH frequency of D3S1295 was higher in occupational TCC patients than that in sporadic TCC patients. The diagnostic accordance rate of patients showed LOH in at least one microsatellite marker with patients diagnosed by pathology was 81.25% (13/16). In the urine sediments from 8 TCC post-operated patients, LOH was found at least with one microsatellite marker.

CONCLUSIONThere could be a different LOH pattern in aromatic amine exposure-associated TCC, and genes near D3S1295 might play a role in the occupational exposure-associated TCC.

OBJECTIVETo study the biological function of killer cell immunoglobulin-like receptor (KIR) and the role of donor inhibitory KIR and recipient genetic background in HLA matched unrelated hematopoietic stem cell transplantation (HSCT).

METHODSHLA genotype of 51 patients (ALL 18 cases, CML 15 cases, AML 10 cases and others 8 cases) and their respective matched unrelated donors from Database of China Marrow Registration was determined by polymerase chain reaction sequence oligonucleotide probes (PCR-SSOP) and sequence specific primers (PCR-SSP). The KIR genotype was determined by PCR-SSP.

RESULTSAll the patients and the donors expressed KIR2DL1, KIR2DL2/L3, KIR2DL4, KIR3DL2 and KIR3DL3. 96.7% individuals expressed KIR3DL1. Among them, 21.57% of KIR was completely identical, while 78.43% was not. Of the non-identical KIRs, 25.49% were the recipient's KIR genotype containing the donor's ones, and 27.45% was the donor's containing the recipient's. 74.62% of donor's KIR2DL1 lacked recipient's C2 ligand, 5.91% of donor's KIR2DL2/L3 lacked recipient's C1 ligand, 19.74% of donor's KIR3DL1 lacked recipient's Bw4 ligand and 54.91% of donor's KIR3DL2 lacked recipient's A3, A11 ligand.

CONCLUSIONKIR genotype and HLA class I antigen are inherited independently. KIR2DLI and KIR3DL2 of donors may cause alloreactivity of NK cell. The mismatch of KIR/HLA in donor-recipient plays a very important role in matched unrelated allo-HSCT. The outcome of HSCT can be better predicted by the model of the presence of KIRs on the donor' sNK cells and the absence of corresponding KIR ligand in the recipient's HLA.

OBJECTIVETo investigate the response rate (RR), time to tumor progression (TTP), quality of life (QOL) and adverse reaction in the treatment of pretreated advanced non-small cell lung cancer (NSCLC) using escalated doses of rh-endostatin (YH-16), and to determine the optimal dose for clinical application.

METHODSIn this phase II randomized, controlled, multicenter trial, the patients were randomly divided into two groups to receive daily 3 hours intravenous infusion of either 7.5 mg x m(-2) or 15 mg/m(2) YH-16 for 28 days.

RESULTSTotally, 68 patients were entered and 60 patients were evaluable. There were no differences in RR (3.0% in both groups, P > 0.05), median TTP (ITT: 60 days versus 71 days, P > 0.05), QOL and incidence rate of adverse reactions (48.6% versus 38.7%, P > 0.05). No significant unexpected adverse events were observed.

CONCLUSIONRh-endostatin may have anti-tumor activity with high clinical benefit rate and is well tolerated in pretreated advanced NSCLC patients. The dose of 7.5 mg x (m(2))(-1) x d(-1) is clinically recommended.
