Objective:To determine distribution of fungal florae of candial balanoposthitis (CBP),the relatioship between antibiotics administration and candial infection and the major source of opportunistic pathogens.Methods:The fungal strains were collected and identified,and the history of antibiotic administration was reviewed.Results:①Foreign fungi were predominant pathogens of CBP;②Dysbacteriosis induced by antibiotics stimulated the growth of foreign fungi,which resulted in CBP;③There was a positive relationship between fungal distribution of male patients and their sexual partners.Conclusion:In order to reduce the incidence of CBP safe coition and reasonalbe administration of antibiotics should be emphasized.

Objective To develop a brachtherapy (BT) dose calculation program based on AAPM TG-43UI formula.With this program we can combine the dose result of external beam radiotherapy (EBRT) and BT together which is calculated by the different treatment planning TPS.Methods BT treatment data, such as source parameter, dwelling position and dwelling time, are retrieved from Nucletron Plato planning system and converted to ADAC planning system coordinate.The BT 3D dose distribution is re-calculated as well.Then the 3D dose distribution is exported to ADAC planning system.In that way, ADAC planning system can display either the EBRT dose or the BT dose and the combined dose can be calculated, displayed and evaluated as well.Results BT dose calculation result of our program which based on AAPM TG-43UI formula is identical with which of Plato (<0.1%).Furthermore, the BT dose can be transfer to the ADAC easily and the dose distributions of combined therapy can be merged in ADAC.Conclusions Our program can be used to combine the dose result of EBRT and BT from different TPS.

ObjectiveTo identify and confirm a novel HLA allele in a Chinese individual.MethodsA new HLA allele was found during routine HLA genotyping by polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSOP) and sequencing-based typing (SBT).ResultsThe new sequence differs from HLA-B * 40:01:01 by two nucleotide substitutions in exon 2 at positions 103 (G＞T) and 106 (A＞G) ; These mutations result in two codon changes:at codon 35 (GCC＞TCC) where an alanine (A) is substituted by a serine(S) and at codon 36(ATG＞GTG) where a methionine(M) is substituted by a valine (V).ConclusionA novel HLA allele,HLA-B * 40:74,was identified,and was named officially by the WHO Nomenclature Committee (HWS10004518 - EF458488).

Background and purpose: Anti-tumor chemotherapy compromises normal immune function of the patients. There were many reports that chemotherapy for advanced colorectal cancer often inhibit the cellular immune function. The effect of FOLFOX regimen chemotherapy on immunity of the patients with colorectal cancer before and after therapy was studied, and healthy people were used as a control. Methods: Eighty colorectal cancer patients were treated by FOLFOX regimen, which consisted of 2-hour infusion of oxaliplatin(85 mg/m~2) and 2-hour infusion of leucovorin (CF)(200 mg/m~2) on Day 1, followed by 5-fluorouracil(5-FU) bolus (400 mg/m~2) on Day 1 and 46-hour infusion (2 400 mg/m~2). FOLFOX regimen was repeated at 2-week intervals. Two treatments of the above regimen were defined as one cycle. Flow cytometry was used to detect T lymphocyte subsets and NK cells in blood samples from patients with colorectal cancer before and after therapy. Data obtained fi'om healthy people was used as control. Results: CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio in blood samples were not significant before and after chemotherapy in first day, second week and fourth week(P0.05). Lower CD3~+, CD4~+ T cells, NK cells and CD4~+/CD8~+ ratio were detected in blood samples from cancer group than that from the healthy control(P<0.05). CD8~+ T lymphocyte were reverse. This change was related to the TNM pathological stage. Conclusion: FOLFOX regimen was effective for patients with coloreetal cancer, which can improve patients' life quality and did not impact on the immune function of the patients. The immune function of lymphocytes in peripheral blood of the patients with colorectal cancer was low, and even worse in the patients with late TNM stage. It is valuable for estimating the function of cell immune of the patients, patients prognosis and the role of immune therapy in the treatment of the patients by detecting T lymphocyte subset and NK cell.

OBJECTIVETo investigate the short-course and efficient way to treat mumps meningitis.

METHODSTotally 155 cases of mumps meningitis treated by intrathecal injection with dexamethasone only once were enrolled as experimental group and 55 similar cases treated with the common therapy as control.

RESULTSThe time for recoveries of temperature, headache, the pathologic reflexes and the total time of treatment were 32 hours, 15 hours, 12 hours and 3.1 days, respectively, while those of the control group were 58 hours, 24 hours, 32 hours, 6.5 days respectively. There was statistical difference between the two groups (P<0.01 or 0.05).

CONCLUSIONSIntrathecal injection with dexamethasone only once is efficient and safe in the treatment of mumps meningitis.

OBJECTIVETo identify a novel human leukocyte antigen (HLA) A allele.

METHODSA new HLA-A allele was found during routine HLA genotyping by polymerase chain reaction-sequence specific oligonucleotide probes (PCR-SSOP) and sequencing-based typing (SBT).

RESULTSThe novel HLA-A*30 allele was identical to A*300101 except that a nucleotide C at position 294 of exon 2 is substituted by A, resulting in codon 98 changed from GAC (D) to GAA (E).

CONCLUSIONA new HLA allele, HLA-A*3020, was identified, and was named officially by the WHO Nomenclature Committee.

OBJECTIVEA novel human leukocyte antigen-B (HLA-B) allele, B*9526, was identified and analyzed by sequencing-based method in a Chinese donor.

METHODSHLA typing was performed by PCR-sequence-specific oligonucleotide (SSO). Molecular cloning and DNA sequencing were used to identify the sequence of the potential novel allele and the difference between this new allele and other known alleles were analyzed.

RESULTSHLA genotyping of one sample gave different results. The sequencing result showed HLA-B alleles of the proband as B*5403 and a novel allele. The nucleotide sequence of the novel allele was different from all known B alleles and harbored one nucleotide change from the closest matching allele B*1507 at nucleotide 425 (A to G) in exon 3, resulting in an amino acid change from Y (TAC) to C (TGC) at codon 142.

CONCLUSIONA novel HLA allele was identified and officially designated as HLA-B*9526 by WHO Nomenclature Committee for Factors of the HLA System.

Objective To explore the relationship between the peripheral dose and radioactive counts of 125I seeds detected by SPECT/CT.Methods Six 125I seeds(1.48×107 Bq, 1.85×107 Bq, 2.22×107 Bq, 2.59×107 Bq, 2.96×107 Bq, 3.33×107 Bq) were put into the solid water phantoms respectively. SPECT/CT was applied to scan the seeds. The radioactive counts (x) at the distance of 1-15 mm from the center of seeds were recorded respectively, while the corresponding doses (y, cGy) were calculated. SPSS 18.0 was used to analyze the relationship between the radioactive counts and peripheral dose. Results There was an exponential relationship between the peripheral dose of 125I seeds and the radioactive counts. The formula was as follow: y=507.849×1.004x. Conclusion SPECT/CT can visualize the peripheral dose of 125I seed, which may provide a method for dosimetric verification after brachytherapy.

Objective An attempt to develop a patient survey questionnaire on the public benefit nature of medical institutions as seen by patients,along with an evaluation of its reliability and validity.Methods A field survey was conducted among the patients visiting these institutions.The Cronbach's α coefficient was calculated to test the reliability.Factor analysis and spearman correlation analysis were applied to test the validity.The validity was also tested by analyzing the demographic factors and comparing the results between different kinds of medical institutions.Results The Cronbach's α coefficient of the questionnaire was 0.853,meanwhile the Cronbach's α coefficient of the three items was 0.845(quality of care),0.845 (suitability of services) and 0.752 (professional ethics).Three common factors were extracted,which coincided with the three items-quality of care,suitability of services and professional ethics.And the results are hardly affected by common demographic characteristics.Condusion The reliability of the questionnaire was acceptable,and the items were reasonably divided in the questionnaire with good structural validity.The questionnaire can be widely applied to evaluate the public benefit nature of medical institutions.
