Objective To study the diagnosis and treatment of the severe pulmonary infection in the patients after kidney transplantation. Methods The clinical data of 26 patients with severe pulmonary infection following kidney transplantation were analyzed retrospectively. Results Microorganisms were isolated and identified in 22 patients out of 26 kidney transplantation patients with severe pulmonary infection. The main etiological pathogens according to their frequency and type were: bacteria (15 cases, including Escherichia coli, Aerobacter cloacae, Klebsiella fredlanderi, Enterococcus faecalis, Staphylococcus epidermidis, etc.), fungi (12 cases, Fermentum, Blastomyces albicans, Candida tropicalis, Aspergillus, etc.), and cytomegalovirus (10 cases). 46.15% (12/26) of patients were infected with one kind of microorganism, and 53.85% (14/26) of patients were mixed infection. In 73.1% (19/26) of patients the pulmonary infection occurred during 1-6 months after renal transplantation. Among 26 patients, 12 developed ARDS, and 4 patients gave up therapies due to high expenses. With energetic treatment, 18 patients (81.82%) were cured and 4 died. Conclusions Intensive care and active measures should be given in the treatment of severe pulmonary infection after kidney transplantation. Early diagnosis, administration of broad-spectrum and combined use of antibiotics, the early identification of pathogens, enforcement in systemic support, including correction of immunosuppression, the timely use of mechanical ventilation to correct hypoxia, are the key treatment strategies for a successful result.

To investigate the change in renal CD11a and myeloperoxidase (MPO) contents and renal function during ischemia-reperfusion injury (IRI) of rat kidney, as well as the role of lymphocyte function associated antigen-1 (LFA-1) played in renal IRI, we utilized a rat model of renal IRI to detect the renal tissue contents of CDlla and MPO and renal functioa The results showed that the levels of CD11a and MPO were very low in normal renal tissue, but increased significantly in ischemia reperfusion. Renal failure was presented in rats with IRI. The levels in the ischemia-60min-reperfusion group were higher than those in the ischemia-30min-reperfusion group in the same time points. Our conclusion is the levels of CD11a and MPO in rat renal tissue increase significantly during renal IRI. LFA-1-mediated leukocyte adherence plays an important role in renal IRI. Up-regulation of CDlla further elucidates the mechanism of relation between IRI and acute rejection: more heavier IRI is, more possible acute rejection would be.

ObjectiveTo investigate the localization G protein couple receptor 30 (GPR30) and its mRNA in submaxillary gland, and to supply theoretic evidence for further studying functional significance of the GPR30 in submaxillary gland of rats. Methods Four male SD rats were sacrificed by cervical dislocation after the intraperitoneal anesthesia, and excised the submaxillary glands. The distribution of GPR30 and its mRNA were studied through immunohistochemistry and in situ hybridization in the experiment. After isolation of the total RNA from the submaxillary gland, RT-PCR was conducted to obtain GPR30 cDNA by using the specific primers. The products of PCR were analyzed by sequencing with Sanger's method. Results The serous acinus epithelial cells and granular convoluted epithelial cells in submaxillary gland of rats showed GPR30 immunoreactivity, which were located in cytoplasm with negative nuclei. GPR30 mRNA hybridized signals were also detected in cytoplasm in the above cells. The products of PCR is identical to that of the GPR30 sequence of rats. Conclusion The serous acinus and granular convoluted epithelial cells not only express GPR30 but also may be a target organ by rapid estrogen signaling pathway in submaxillary gland of rats. This may be involved in the functional regulation of submaxillary gland.

Objective To investigate the relationship between activity of plasma platelet-activating factor acetylhydrolase (PAF-AH)and insulin resistance (IR) in patients with polycystic ovary syndrome (PCOS). Methods From Oct. 2006 to Jan. 2008, 105 PCOS patients undergoing treatment in Department of Obstetrics and Gynecology of Second Hospital affiliated to West China University were enrolled in the study, among 53 cases with homeostatic model assessment IR (HOMA-IR) exceed or equal 2.77 as IR-PCOS group and 52 cases with HOMA-IR less than 2.77 as non IR-PCOS group. In the mean time, 53 infertile women due to fallopian tube or husband factors were chosen as control group. Plasma PAF-AH activity, high-density lipoprotein-associated PAF-AH (H-PAF-AH) activity, low-density lipoprotein-associated PAF-AH (L-PAF-AH) activity, the ratio of L-PAF-AH to H-PAF-AH activity were measured and compared among three groups. The method of Pearson correlation analysis and stepwise multiple regression analysis were used to study the relationship between the ratio of L-PAF-AH to H-PAF-AH activities and hormonal and metabolic parameters. Results (1) Plasma PAF-AH activity [ (0.055±0.012) mmol· L~(-1)·min~(-1)], L-PAF-AH activity [(0.052±0.012) mmol·L~(-1)·min~(-1)], and the ratio of L-PAF-AH to H-PAF-AH activity (23±6) in the IR-PCOS group were significantly higher than those at control group [(0.050±0.009) mmol·L~(-1) ·min~(-1), (0.047±0.009) mmol·L~(-1)·min~(-1) and (18±4)] and non-IR-PCOS group [(0.050±0.0012) mmol·L~(-1) ·min~(-1), (0.048±0.012) mmol·L~(-1)·min~(-1) and (18± 5 ), P <0.05 ]. The ratio of L-PAF-AH to H-PAF-AH activities at IR-PCOS group was also significantly higher than those at Non IR-PCOS and control group after correction for body mass index (P<0.01). (2) Pearson correlation analysis showed that the ratio of L-PAF-AH to H-PAF-AH in PCOS patients was positively correlated with atherogenic index, age, body mass index, waist-to-hip ratio, HOMA-IR, triglyceride levels, fasting insulin levels, fasting glucose levels, low density lipoprotein cholesterol and total cholesterol (r=0.644, 0.247, 0.296, 0.212, 0.356, 0.587, 0.377, 0.375, 0.292 and 0.199, respectively, P<0.05), and negatively correlated with high density lipoprotein cholesterol (r=-0.510, P<0.05). The multiple stepwise regression analysis showed that atherogenic index and triglyceride were significant variables for the ratio of L-PAF-AH to H-PAF-AH activity (standardized coefficient, β=0.515 and 0.201, respectively, P<0.05). Conclusion The elvated L-PAF-AH activity may be associated with IR in PCOS patients, and the increased ratio of L-PAF-AH to H-PAF-AH activities may be a potential marker of inflammation in the patients.
