Objective To investigate the relationship between air pollution and respiratory diseases in Nanning. Methods To analyze the prominent pollutants in the last 12 years: total suspensible particulate (TSP), drop dust, sulphur dioxide (SO2) and nitrogen oxide (NOx) by using Shanghai Air Quality Index, and study the correlation between the above data and the constituent ratio of chronic odstructive lung disease(COPD) inpatients of Guanxi Zhuangzu Autonomous Region People's Hospital as well as the mortality of respiratory diseases in Nanning in the same period. Results The air pollution in Nanning was classified into coal pollution. The dominating pollutants were TSP, drop dust, SO2 and NOx. The epidemiology research showed that the mortality of respiratory diseases in industrial zone were 1.4-2.4 times of that in the city zoon, the city zone was less higher than suburb. During the most severe air pollution period in 1991-1995, the mortality of respiratory diseases was highest, and the inpatients of COPD in the hospital was relevant higher. Conclusion Air pollution is the primary environmental pathogeny and fatal factor for respiratory diseases.

Objective To investigate the relationship between plasma neuropeptide Y(NPY) and asphyxia in newborns. Methods Thirty-seven patients with neonatal asphyxia (asphyxia group) and 33 healthy pregnant women(control group )in their third trimester were chosen. The concentrations of plasma NPY were measured by radioimmunoassay. Results The levels of NPY in umbilical artery plasma was (187.47? 46.63) ng/L in asphyxia group,and (115.33?29.42) ng/L in control group. There were significant difference between them ( P 0.05). Conclusions The neonatal asphyxia was associated with NPY. NPY might play an important role in the pathophysiological changes in neonatal asphyxia.

OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.

METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.

RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).

CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.

Objective To study the clinicopathologic features of post-transplant lymphoproliferative disorders (PTLD) following renal transplantation.Methods Four cases of PTLD following renal transplantation were studied and relevant literatures were reviewed.Results All the 4 cases had received 3-drug-immunosuppression after transplantation.The duration between renal transplantation and diagnosis of PTLD was 5-112 months,averagely 34 months.The patients were suffered from infective monocytic hyperplasialike PTLD,plasmacytic hyperplasialike PTLD,polymorphic PTLD and monomorphic PTLD respectively in morphology and had no specific symptoms.All the patients received therapy with dosage reduction of immunosuppressants and some received rituximab or chemotherapy.The case of monomorphic PTLD died in a short time after diagnosis.Conclusion PTLD is a lymphoproliferative disease with distinctive morphologic and clinical characteristics.The main treatments include the dosage reduction of immunosuppressive agents,biotherapy and chemotherapy.The prognosis of monomorphic PTLD is poor.

Objective To investigate the signal transducer and activator of transcription 1(STAT1) and matrix metalloproteinase 3(MMP3)′s genetic expressions and their clinical significance on urothelial carcinoma after renal transplantation. Methods Fifty-one patients with urothelial carcinoma were recruited in this study. Sixteen of them who had renal transplant were in the experimental group and 35 of them without renal transplant were in the control group. All the cases had been proved postoperatively having transitional cell carcinoma by histopathological study. The human genome oligo arrays were used to analyze the gene expression spectrum of urothelial carcinoma after transplantation, aiming the STAT1 and MMP3's expression. Real time RT-PCR and immunohistochemical staining were used to compare the differences in the 2 groups. Results The experimental group showed that there were 35 genes up-regulated compared with the control group. Of them, 23had known gene function or partly known, and 12 had unknown gene function. There were 76 genes down-regulated. Of them, 46 had known gene function or partly known, and 30 had unknown gene function. After pathway analysis of the differentially expressed genes, there were 23 groups of pathways which had significant differences (P＜0.05), referring to the aspects of immunosuppressive and tumor growth. The levels of STAT1 and MMP3 expressions had significant differences between the 2groups(P＜0.05)as well. Conclusions The differential expression of urothelial tumor genes is obvious between patient who has had renal transplant and who has not. There are many aspects that are related to the tumor's growth like signaling pathways regulating proliferation, apoptosis of tumor cells, tumor angiogenesis and the tumor metastasis potential. STAT1 and MMP3 maybe become the targets of chemoprevention for post-transplantation urothelial carcinoma.
