OBJECTIVETo investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG).

METHODSOne hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin-2 (IL-2), peripheral T-lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno-equilibrium method, and compared with normal control.

RESULTSThere were disorders of T-lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL-2 (P < 0.05 or P < 0.01). These abnormalities could be normalized after YSKG treatment.

CONCLUSIONFunctional disorders of cellular and humoral immunity exist in CPN patients of chronic stage, YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.

Objective To report clinical manifestations, electroencephalogram (EEG), and the genotypes of two siblings with type Ⅲ Gaucher disease.Methods Two patients with different features were siblings. Their clinical data, signs, peripheral leukocytes acid β-glucosidase activity, andGBA gene were analyzed.Results (1) The proband was a boy. He visited us at the age of nine years old because of hepatosplenomegaly, thrombocytopenia and growth retardation without any neurologic symp-toms. He had normal intelligence but abnormal EEG ifndings. The activity of acid β-glucosidase in his leucocytes decreased to 1.5 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr), supporting the diagnosis of type Ⅲ Gaucher disease. (2) The elder sister of the proband was 12 years old. She had tonic-clonic seizure and myoclonus seizure from the age of seven years old. Mild hepatomegaly, abnormal EEG, poor effect for antiepileptics, and progressive deterioration of psychomotor abilities were found. Her blood leucocytes acid β-glucosidase activity decreased to 1.8 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr). Two heterozygous missense mutations, c.680A>G, (p.N188S) and c.1342G>C (p.D409H) were detected from the two siblings, respec-tively.Conclusions Patients with type Ⅲ Gaucher disease usually have the onset in childhood with typical features of Gaucher disease without neurologic involvement. Abnormal EEG may be helpful to the differential diagnosis of type I or type Ⅲ. On the other hand, neurologic manifestations could be presented as the ifrst symptom in some patients without viscera enlargement. The patients of type Ⅲ Gaucher disease with the same genotype could have different phenotypes, even between the siblings.

The depositions of immunoglobulins on the retina of diabetic rat were studied with immunohistochemistry,immunofluorecence and computer analysing system.In comparison with control group, depositions of IgG,IgA and IgM on the retina of diabetic rat induced by streptozotocin were significantly increased (all P＜0.05 ).So the immunoglobulin depositions may contribute to the pathogenesis of diabetic retinopathy.

0.05).Conclusion CYPIA1 MspⅠ polymorphism is not related to the susceptibility to colorectal carcinoma.

BackgroundDiabetic retinopathy (DR) is the result of the cytokine network disorders,the imbalance of angiogenic factor and vascular inhibitory factor is the start factor.ObjectiveTo analyze the levels of CXC chemotatic factors of type 2 diabetes mellitus patients,evaluate the clinical application value of them in different clinical types of DR using receiver operating characteristic (ROC)analysis and to approach the new way of individualized treatment.Methods This was a prospective research.The gold standard was ophthalmolscope and fundus fluorescein angiography.The levels of CXC chemotatic factors and multiplicaiton factors were measured in 96 cases with type 2 diabetes mellitus (66 cases with retinopathy and 30 cases without retinopathy as control).The assessment tasks were performed for these index and courses of DR with ROC curve.Results The expression of age,course of disease has significant difference in different courses of DR ( F =8.507,P =0.001 ; F =28.143,P =0.000).Compared with the control group,the expression of growth-related oncogene-α ( GROα ) ( t =- 2.172,P =0.035,AUC =0.625 ),whole blood viscosity 200 ( t =- 3.724,P =0.001,AUC =0.904 ) and neutrophilic leukocyte (t=-2.562,P =0.013,AUC =0.577 ) has significant difference in the group of mild NPDR.Compared with the control group,the expression of interferon-γ-inducible protein 10 ( IP-10 ) ( t =-3.591,P =0.001,AUC =0.592 ),platelet derivation growth factor-BB ( PDGF-BB ) ( t =- 3.233,P =0.003,AUC =0.735 ),vascular endothelial growth factor(VEGF) ( t =- 3.617,P =0.001,AUC =0.776 ),C peptide ( t =- 3.366,P =0.002,AUC =0.962 ),leukocyte ( t=-3.201,P =0.003,AUC =0.852) and neutrophilic leukocyte(t =-4.201,P=0.000,AUC =0.852) has significant difference in the group of moderate and severe NPDR.ConclusionsCXC chemotatic factors may act as reactivator in the pathogenesis of DR,GROα and IP-10 may be useful for clinical monitoring of the severity of DR,and evaluating the imbalance state of chemotatic factors maybe a new approach to clinical monitoring and prognosis of DR.

Objective: To analyze the relationship between thrombin activatable fibrinolysis inhibitor ( TAFI ) and coronary heart disease ( CHD ), and to provide evidence for the prevention of CHD. Methods: The patients with CHD in Fushun Central Hospital in Liaoning Province were selected as the case group, the patients without CHD in the same hospital and period were selected as the control group. The demographic information and clinical examination results ( serum TAFI, lipid, glucose, etc. ) were collected to analyze the association between TAFI and CHD by logistic regression models.The multivariate logistic regression analysis was used to explore the relationship between TAFI and CHD. Results: There were 222 cases, including 100 cases of stable angina, 44 cases of unstable angina and 78 cases of acute myocardial infarction, and 222 controls. The median ages of cases and controls were 62 and 57 years old. The results of multivariate logistic regression analysis showed that serum TAFI>22.88 μg/mL ( P75 of controls ) was associated with the risk of CHD ( OR=1.619, 95%CI: 1.011-2.593 ), unstable angina ( OR=2.917, 95%CI: 1.433-5.939 ) and acute myocardial infarction ( OR=2.626, 95%CI: 1.007-6.847 ). Conclusion The high level of TAFI is related to CHD, unstable angina and acute myocardial infarction.

Objective to explore the current situation and related influencing factors on the retention time of patients receiving methadone maintenance treatment (MMT). Methods Information on basic situation and daily treatment of the patients were collected from the 7 MMT clinics opened in the pro-two batch in Hunan province. Retention rate and influencing factors were analyzed. Results (1) The retention rates after 6 and 12 months of MMT became 72.06% and 49.65% respectively. (2) The retention rates of high-dosage group and low-dosage group were 85.03% and 68.03% after 6 months on MMT program while became 60.48% and 46.28% after 12 months of MMT respectively. (3) The mean retention time of HIV+ patients and HIV- patients were 9.46 months and 8.62 months respectively during the 12 months follow-up observation, showing a significant difference. (4) Patients who took large dose methadone, did not share needles, at older age or HIV+ , were prone to keep MMT at a long period. Conclusion The retention rates for 6 months and 12 months in the MMT program in Hunan province were similar to the national data. Dose, type of drug abuse, age and HIV status were related to the period of retention.

OBJECTIVETo understand the metabolic patterns of NAA, Cr and Cho in radiation encephalopathy (RE) induced by radiotherapy for nasopharyngeal carcinoma detected by proton magnetic resonance spectroscopy (1H-MRS), and provide useful evidence for early diagnosis of this disease.

METHODSChemical shift imaging 1H-MRS was performed for 10 healthy volunteers (control group) and 21 patients with pathologically confirmed nasopharyngeal carcinomas, who developed RE after radical radiotherapy as diagnosed on the basis of clinical symptoms and imaging findings. The contents of NAA, Cr and Cho in the pixels were observed, the metabolic maps generated, and NAA/Cr and NAA/Cho ratios calculated for all the subjects.

RESULTSThe concentrations of NAA, Cr and Cho were rarely observed in the necrosis and liquefaction foci in the patients, nor were any signals displayed on their metabolic maps. In the visible lesions, with the exception of the necrosis and liquefaction foci, the content of NAA increased slightly, whereas that of Cr or Cho decreased obviously or even became absent. An area around the lesion was identified where NAA content decreased but Cr or Cho increased. The signal in the metabolic maps appeared indistinguishable. The NAA/Cr and NAA/Cho ratios were less than 1. Farther away from the visible lesions, the NAA, Cr and Cho contents remained normal with NAA/Cr and NAA/Cho ratios of less than 1.

CONCLUSION1H-MRS is capable of displaying the patterns of metabolite changes in RE induced by radiotherapy, and identifying larger area of abnormal metabolism in RE than the visible lesion in MRI, which suggests the possibility of earlier detection of RE with 1H-MRS.

Abuse of pharmaceutical drugs is a major public health and social problem worldwide. Mostly abused drugs mainly include opioids such as morphine, tramadol, methadone and fentanyl, sedative-hypnotics such as benzodiazepines and non-benzodiazepines, and central stimulants such as Ritalin (methylphenidate), Adderall (amphetamine and dextroamphetamine) and modafinil. Abuse of pharmaceutical drugs not only causes direct damage to multiple systems of the body, but also significantly increases risks of mental and physical diseases, imposing a heavy burden on individuals, families and society. Therefore, the prevention and control of pharmaceutical drug abuse are of vital importance. The Chinese government has taken strict administration measures for pharmaceutical drugs with abuse risk. However, confronting endless new drugs and changing abuse trends, it is necessary to further strengthen management and prevention of pharmaceutical drugs, monitor the trend of abuse, establish rapid response mechanisms, popularize relevant knowledge, and develop specific therapeutic drugs and intervention means, in order to promote prevention and treatment of pharmaceutical drug abuse.
