OBJECTIVE:To prevent and reduce the occurrence of nosocomial deep mycosis.METHODS:The medical records of patients with nosocomial deep mycosis in the period from January2001to December2002in this hospital were ret?rospectively analysed.RESULTS:There were43patients with nosocomial deep mycosis,which accounted for10.54%of all nosocomial infections in the same period.The predilection sites were respiratory tract(34.88%)and digestive tract(30.23%). The main pathogen was Candida albicans(77.78%).All patients had serious underlying diseases and were treated with broad-spectrum antibiotics,and some of them had received adrenocortical steroids.CONCLUSION:Rational use of broad-spectrum antibiotics and adrenocortical steroids is the most important way to prevent deep mycosis and improve the prognosis.

Objective To evaluate cytotoxic effects of cytokine-induced killer cells (CIK cells) transfected with the interleukin-2 (IL-2) gene on malignant melanoma cells.Methods Mouse spleen cells were extracted,lymphocyte cells were separated,and CIK cells were prepared from these lymphocyte cells.PEGF-N1 plasmids containing IL-2 gene (PEGF-NI-IL-2) were transfected into CIK cells.Fluorescence microscopy was used to observe transfection products,and reverse transcriptase-polymerase chain reaction (RT-PCR) was conducted to determine the IL-2 mRNA expression.Then,effector cells such as CIK cells and IL-2-transfected CIK cells were separately co-cultured with target cells (B16 melanoma cells) at effector-target ratios of 10∶ 1,20∶1 and 40∶1,then 4-hour lactate dehydrogenase release assay was performed to evaluate cytotoxic effects of the two kinds of CIK cells on B 16 cells.After effector cells were cocultured with target cells at the effector-target ratio of 40∶1 for 48 hours,enzyme-linked immunosorbent assay (ELISA) was conducted to detect levels of IL-2,interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) in the supernatant of the two kinds of CIK cells.Finally,mouse models of melanoma were established,and a total of 28 melanoma-bearing mice were divided into 4 groups to be peritumorally injected with 0.2 ml sodium chloride physiological solution (control group),100 IU IL-2 solution (IL-2 group),CIK cell suspension at a cell density of 1 × 106 cells per milliliter (CIK group) and IL-2-transfected CIK cell suspension at a cell density of 1 × 106 cells per milliliter (IL-2-transfected CIK group) respectively.Tumor morphology,tumor inhibition rate and cell apoptosis rate were used to evaluate tumor growth in the above groups.If data were normally distributed,t-test was used for comparing means between two groups,and analysis of variance and least significant difference (LSD)-t test were used for comparing means among multiple groups.Results Fluorescence microscopy and RT-PCR both showed that IL-2 was successfully transfected into CIK cells.The cytotoxic effect of IL-2-transfected CIK cells on B16 cells was strongest at the effector-target ratio of 40:1.Levels of IL-2,IFN-γ and TNF-α were also significantly higher in the supernatant of IL-2-transfected CIK cells [(1107.26 ± 6.49) pg/ml,(50.01 ± 3.35) pg/ml,(39.86 ± 3.25) pg/ml] than those in that of CIK cells [(51.09 ± 3.85) pg/ml,(32.71 ± 2.43) pg/ml,(30.11 ± 3.08) pg/ml,t =442.60,14.93,6.89,all P ＜ 0.01].Animal experiments showed that the tumor volume obviously increased in the control group (P ＜ 0.05),but significantly decreased in the IL-2 group,CIK group and IL-2-transfected CIK group (all P ＜ 0.001) after intervention compared with those before intervention.Furthermore,the tumor volume in the IL-2-transfected CIK group was significantly less than that in the other three groups (all P ＜ 0.01),but no significant difference was observed between the IL-2 group and CIK group (P ＞ 0.05).In addition,the apoptosis rate was significantly higher in the IL-2 group,CIK group,and IL-2-transfeeted CIK group than that in the control group (all P ＜ 0.01).The apoptosis rate and tumor inhibition rate were significantly higher in the IL-2-transfected CIK group than those in the IL-2 group and CIK group (all P ＜ 0.01),but insignificantly different between the IL-2 group and CIK group (P ＞ 0.05).Conclusion IL-2-transfected CIK cells had stronger killing effects on malignant melanoma.

objective To evaluate the influence of HLA matching and new immunosuppressants on pre-venting acute rejection of renal allograft in sensitized recipients. Methods 751 recipients underwent renal transplantation were enrolled in this study including 46 sensitized recipients (study group) with PRA be-tween 10%-90% and 705 non-sensitized recipients (control group) with PRA less than 10% pretransplant. All patients in the study group received induction course (ATG 100 mg/d, 5-7 d) plus triple-immunosup-pressive therapy including FK506 + MMF + steroid. The rate of acute rejection and delayed graft function after renal transplantation was analyzed. The influence of HLA matching on preventing acute rejection was al-so evaluated. Results The acute rejection rate in the study group and control group was 30.43% and 19. 57%, respectively, (P < 0.05). The rate of delayed graft function was 60.86% in the study group, signifi-cantly higher than that of the control group (11.87%). There was no statistically difference of one-year pa-tient / graft survival rotes between the two groups. The average serum creatinin levels at one-year posttrans-plantation were similar between the two groups (130 mmol/dl in the study group and 125 mmol/di in the control group). The average loci of HLA matching in the study group (4.2) was significantly higher than that in the control group (2.8). The acute rejection rate in the study group was significantly higher when lo-ci of HLA mismatch ranging from 2-4 compared with loci of HLA mismatch less than 2. The acute rejection rate was significantly higher in the highly sensitized recipients (PRA ranging from 50% -90% pretmnsplant) than that in the less sensitized (PRA ranging from 10% to 20% pretransplant) in the study group. Patients with higher PRA level posttransplantation were prone to developing acute rejection. Conclusion HLA matching and new immunosuppressants can reduce the incidence of acute rejection in sensitized recipi-ents and increase the survival rate of patients and allografts.

Objective To investigate the incidence of infection and the effect of anti-infection prophylaxis in renal transplanted patients after Basiliximab induction therapy. Methods A total of 204patients who have received renal transplantation and Basiliximab induction therapy from January 1,2001 to December 31, 2010 in our hospital have been retrospective analysed in this study. These patients were divided into a prophylaxis group (118 cases) with Ganciclovir + Sulfadiazine +Trimethoprim therapy and a control group (86 cases) without any anti-infection prophylaxis.Furthermore, 440 transplanted patients in the same peroid without any induction therapy were also analysed. They were also devided into two groups: an anti-infection prophylaxis group (206 cases)and a control group (234 cases) without any anti-infection prophylaxis. Results In the prophylaxis group with Basiliximab induction therapy, there were 23 patients (19. 5 %, 23/118)experienced hospitalization due to infection, 3 cases (13. 0 %,3/23) among them were severe infection, and 3patients (13.0 %, 3/23) died from vital infection. In the non-prophylaxis control group with Basiliximab induction therapy, 27 patients (31.4 %, 27/86) had infection complication, 7 patients (25.9 % ,7/27) among them were severe infection, and 4 patients(14. 8 % ,4/27)died. The incidence of infection between the above two groups is significantly different (P＜0. 05). In the prophylaxis group without induction therapy, the incidence of infection was 15.0 % (31/206), there were no severe infection cases but 7 patients (22. 6 %, 7/31) died from infection. In the non-prophylaxis control group without induction therapy, the incidence of infection was 12. 8 % (30/234), 3 cases among them were severe infection(10. 0 %,3/30)and 5 patients died from infection (16. 7 %, 5/30).The incidence of infection in Basiliximab induced patients without anti-infection prophylaxis is significantly higher than that in patients without induction therapy and anti-infection prophylaxis (31.4 % vs. 12.8 %,P＜0.01). Conclusion Basiliximab induction therapy increased the risk of infection, but not the rate of mortality. It is necessary to give anti-infection prophylaxis in renal transplanted patients with Basiliximab induction therapy.

Objective To investigate the iodine nutritional status of targeted population in the high-risk areas of iodine deficiency disorders in Chongqing, so as to provide scientific evidence for establishing prevention and remedial measures. Methods Six towns were selected in Chengkou and Wuxi Counties to found suspected dementia patients born after first Jan, 1997. Two hundred children aged 8-10 years were investigated in every town. The thyroid volume, intelligence quotient(IQ) and urinary iodine of the children were examined. Forty women (pregnant and nursing women) were investigated in every town. The iodine content of salt from their home was measured. The thyroid volume was examined by palpation and B-uhrasound. IQ was measured by combined Raven Test in China(CRT-RC2). Urinary iodine was determined using the acid digest arsenic-cerium contacting method, and iodined salt was detected using direct titration method. Results Six suspected dementia patients were found in the local town hospital. Five eases were excluded. There was 1 case born in other place. The rates of goiter by palpation and B-ultrasound were 9.58%(92/960) and 8.89%(65/731), respectively. The median of urinary iodine of children and women was 319.15 μg/L and 248.42 μg/L, respectively. The mean of IQ of the children was 103.32. The coverage rate of iodine salt from residents was 98.82%(336/340). Conclusions The iodine nutrition of children was good and there is no newly occurred cretinism in Chengkou and Wuxi Counties. Goiter rate and median of urinary iodine aged 8-10 years and of women, coverage rate of iodine salt from resident has meet the standard set for basical elimination iodine deficiency disorders.

The academic origin of homogeny of spleen and pancreas is explained from the aspect of Chinese medicine.The authors think spleen faihng to spread essence is the basic pathogenesis to diabetes mellitus.Spleen function of spreading essence is impaired.Thus essence of water and grain could not be spread in the whole body but amass sugar-turbidity,which manifests high blood sugar.Differentiating diabetes mellitus from the viewpoint of spleen,invigorating spleen and benefiting Qi could help spleen to ascend clear.Invigorating spleen-yin and clearing endogenous heat are used.The liver and kidney should be considered.The methods of dissipating phlegm and activating blood circulation could be combined.The treating idea of treating spleen is treating pancreas should be used in preventing and treating diabetes mellitus.

Objective:To investigate the mutations of the epidermal growth factor receptor (EGFR) gene and its clinical signifi-cance in non-small cell lung cancer (NSCLC). Methods:The EGFR gene mutations of exons 18 to 21 in NSCLC were detected by us-ing the ADx-ARMS? detection kit method. Results:The total mutation percentage in exons 18 to 21 of the EGFR gene was 45.8%(98/214) in NSCLC. These mutations predominantly occur in exons 19 and 21. EGFR gene mutation percentages were found in exons 18 (0.93%, 2/214), 19 (22.0%,47/214), 20 (2.3%, 5/214), and exon 21 (20.6%, 44/214) in the NSCLC. Two NSCLC cases were identified to have double EGFR gene mutations of exons 19 and 21. EGFR gene mutations were more frequently observed with adenocarcinoma histology (50.3%, 93/185) than with squamous cell carcinoma (17.2%, 5/29) (P=0.001). EGFR gene mutations occur more frequently in NSCLC cases in women than in men (P=0.002). EGFR gene mutations were significantly higher in NSCLC with lymphatic metastasis (66.7%) than in NSCLC without lymphatic metastasis (39.5%) (P<0.05). However, no evident association was found between EGFR gene mutations and age, as well as tumor grade and clinical stage of NSCLC (P>0.05). Conclusion:NSCLC, especially lung adenocar-cinomas, has exhibits frequent EGFR gene mutations in China. EGFR gene mutations in exons 19 and 21, combined with the clinical pathological features of lung cancer, can serve as the molecular marker to evaluate the efficacy of EGFR TKI for NSCLC patients.
