Objective To understand the prevalence of anemia and its influencing factors in infants aged 6 to 24 months in poor areas of Gansu Province, and to provide reference for improving the prevalence of anemia in local children. Methods A multi-stage sampling method was used to conduct a survey on infant and caregivers, in the 12 children nutrition improvement project counties in Gansu Province. T-test and analysis of variance were used to compare the hemoglobin content, the chi-square test was used to compare the prevalence of anemia, and the Logistic regression model was used to analyze the influencing factors. Results Among the 3 188 effective data, the detection rate of anemia was 25.69% (819). The detection rate of anemia among boys and girls was 24.54% and 26.90%, respectively. There was no significant difference in the detection rate of anemia among different sexes ( 2=2.326, P=0.127). The detection rate of anemia between different age groups were statistically significant ( 2=42.339, P<0.001); The results of multivariate analysis showed that children's age, children's ethnic groups, parents' awareness of feeding knowledge, the feeding method of 6 months after birth and the way of taking nutritional packs were associated with anemia (all P<0.05). Conclusions The prevalence of anemia in infants aged 6 to 24 months in poor areas in Gansu Province was relatively high. Strengthening the education of caretakers’ knowledge of guardian feeding and scientific child-rearing, and ensuring the nutrition packages intake can significantly reduce the prevalence of anemia prevalence in poor areas in Gansu Province.

OBJECTIVETo explore the therapeutic methods of adrenal incidentalomas.
METHODSThe data of 156 cases were analyzed retrospectively.
RESULTSThe operation were performed in 151 cases, radiotherapy and chemotherapy in 1 case and follow up in 4 cases. The diameter of the tumors were 1.3-15.0 cm. Pathological results indicated that 34 cases were pheochromocytoma, 83 adrenal cortical adenoma, 5 adrenal cortical carcinoma, 3 metastases carcinoma, and 26 other benign tumors. One hundred and thirty-six cases were followed-up for 1-7 years. 3 cases of metastases carcinoma died in 1.5 years, 2 cases of cortical carcinoma died in 2.0 and 2.5 years for recurrence and metastases. One hundred and thirty-one cases survived healthy, 3 cases of them take orally dexamethasone for 1 year after post-operation.
CONCLUSIONSSurgical operations should be performed in malignant tumors, hypersecretion tumors, deuto-clinical adrenal cortical tumors, pheochromocytoma and those whose diameters of tumors are over 3 cm. But those whose tumors had non-hypersecretion and diameters are less than 3 cm should be followed up closely.

OBJECTIVETo investigate the clinical methods for reducing bladder cancer recurrence after surgical treatment for renal pelvic carcinoma.
METHODSFrom October 1997 to December 2007, the data of 227 patients undergoing total nephroureterectomy for clinically localized transitional cell carcinoma of the renal pelvis with follow-up results were analyzed retrospectively, including 126 cases of male and 101 cases of female, and the age was 34 to 78 years old. There were 2 kinds of technique used in the dissection of bladder wall circumferentially around the ureteral orifice. Technique A was dissection along the ipsilateral ureter to the bladder wall. Technique B was dissection along the vas deferens to the bladder wall circumferentially around the ipsilateral ureteral orifice and division of the lateral vesical ligament to reach the seminal vesicle. Prophylactic intravesical chemotherapy included 3 method. Method 1 was intraoperative intravesical chemotherapy and then administrated once a week, 10 times in total. Method 2 was intraoperative intravesical chemotherapy and then administrated once a week from the 4(th) week after operation, 10 times in total. Method 3 was intravesical chemotherapy was given once a week from the 4(th) week after operation, 10 times in total. The time of follow-up was 1 to 10 years with regular cystoscopy. Chi-square test and Logistic regression were used to analyzed the recurrence rate of bladder cancer.
RESULTSRecurrence rate of bladder cancer was 27.8% (63/227). The recurrence rates of bladder cancer in patients using technique A and B were 18.0% (7/39) and 12.5% (3/24), respectively (P < 0.05). The postoperative recurrence rates of bladder cancer in patients using 3 kinds of intravesical chemotherapy regimen were 17.9% (11/67), 20.8% (10/48) and 33.3% (17/51), respectively. There was significant difference between the recurrence rates of patients using method 1 and method 3 intravesical chemotherapy (P < 0.05).
CONCLUSIONComplete removal of the bladder mucosa circumferentially around the ureteral orifice, administration of the intraoperative intravesical chemotherapy instillation and instillation once a week may be a useful approach to reduce the recurrence of bladder cancer after operation for renal pelvic carcinoma.

BACKGROUNDAlthough traumatic brain injury can lead to opening the blood-brain barrier and leaking of blood substances (including water) into brain tissue, few studies of brain antigens leaking into the blood and the pathways have been reported. Brain antigens result in damage to brain tissues by stimulating the immune system to produce anti-brain antibodies, but no treatment has been reported to reduce the production of anti-brain antibodies and protect the brain tissue. The aim of the study is to confirm the relationship between immune injury and arachnoid granulations following traumatic brain injury, and provide some new methods to inhibit the immune injury.
METHODSIn part one, methylene blue was injected into the rabbits' cisterna magna after traumatic brain injury, and concentrations of methylene blue and tumor necrosis factor (TNF)-α in blood were detected to determine the permeability of arachnoid granulations. In part two, umbilical cord mesenchymal stem cells and immature dendritic cells were injected into veins, and concentrations of interleukin 1 (IL-1), IL-10, interferon (IFN)-γ, transforming growth factor (TGF)-β, anti-brain antibodies (ABAb), and IL-12 were measured by ELISA on days 1, 3, 7, 14 and 21 after injury, and the numbers of leukocytes in the blood were counted. Twenty-one days after injury, expression of glutamate in brain tissue was determined by immunohistochemical staining, and neuronal degeneration was detected by H&E staining.
RESULTSIn part one, blood concentrations of methylene blue and TNF-α in the traumatic brain injury group were higher than in the control group (P < 0.05). Concentrations of methylene blue and TNF-α in the trauma cerebrospinal fluid (CSF) injected group were higher than in the control cerebrospinal fluid injected group (P < 0.05). In part two, concentrations of IL-1, IFN-γ, ABAb, IL-12, expression of glutamate (Glu), neuronal degeneration and number of peripheral blood leukocytes were lower in the group with cell treatment compared to the control group. IL-10 and TGF-β were elevated compared to the control group.
CONCLUSIONSTraumatic brain injury can lead to stronger arachnoid granulations (AGs) permeability; umbilical cord mesenchymal stem cells and immature dendritic cells can induce immune tolerance and reduce inflammation and anti-brain antibodies to protect the brain tissue.

OBJECTIVETo evaluate the value of a new platelet function test PFA P2Y (PFA-200) in monitoring clopidogrel treatment for cardiovascular disease in elderly patients.
METHODSFifty-six elderly patients receiving clopidogrel therapy in the Department of Cardiology of General Hospital of PLA from March to August in 2016 and 85 healthy volunteers were recruited for analysis. All the subjects underwent PFA P2Y, LTA (light transmittance aggregometry) and TEG (Thromboelastograph) tests, and Spearman correlation coefficients were used to test the associations between test results. The agreement among the 3 platelet function test methods was assessed using Cohen's kappa coefficient.
RESULTSCorrelation coefficient (r) was -0.701 (P<0.001) between PFA P2Y and LTA, and 0.475 (P<0.001) between PFA P2Y and TEG. The agreement was 75% between PFA P2Y and LTA and 67.9% between PFA P2Y and TEG. The κ value was 0.434 (P=0.001) between PFA P2Y and LTA and 0.242 (P=0.046) between PFA P2Y and TEG. With ADP-induced maximum platelet aggregation rate of LTA >50% as the laboratory clopidogrel resistance, the cut-off value of PFA P2Y was 119 s (AUC=0.733) with a sensitivity of 75.6% and a specificity of 73.3%.
CONCLUSIONPFA P2Y has a moderate correlation and agreement with LTA, but has a poor correlation and agreement with TEG. PFA P2Y can be useful for assessing the effects of clopidogrel therapy and the association of the cut-off value (119 s) with the long-term clinical ischemic events needs be confirmed in further study.

OBJECTIVETo investigate the anatomical interaction between uncinate process and agger nasi cell to better understand the anatomy of the frontal sinus drainage pathway by endoscopy, spiral computed tomography (CT) and sectioning.
METHODSTwenty-one skeletal skulls (forty-two sides) and one cadaver head (two sides) were studied by spiral CT together with endoscopy and collodion embedded thin sectioning at coronal plane. The sections with the thickness of 100 microm were stained with hemotoxylin and eosin.
RESULTSUnder endoscopy, a leaflet of bone to the middle turbinate, which is given off by uncinate process, forms the anterior insertion of the middle turbinate onto the lateral nasal wall. The middle portion of the uncinate process attached to the frontal process of the maxilla in all of the skeletal nasal cavities, as well as the lacrimal bone in 78.6% of the skeletal nasal cavities. On CT scans, the agger nasi cell is present in 90.5% of the skeletal nasal cavities. While the lateral wall of the agger nasi cell is formed by lacrimal bone, the medial wall of the agger nasi cell is formed by uncinate process. And the anterior wall is formed by the frontal process of the maxilla. The superior portion of the uncinate process forms the medial, posterior and top wall of the agger nasi cells. The superior portion of the uncinate extends into the frontal recess and may insert into lamina papyracea (33.3%), skull base (9.5%), middle turbinate, combination of these (57.2%).
CONCLUSIONSThe agger nasi cell is the key that unlocks the frontal recess.

OBJECTIVETo ascertain the causation of a pregnant woman with undefined pneumonia reported from the People's Hospital of Tongling city in Anhui province on November 2005.
METHODSEpidemiological and clinical information of the case was collected from the keypersons close to the case and referring to the medical record. A medical observation was carried out on the close contacts of the case and sick or dead poultry. Tracheal aspirates being collected were tested by both RT-PCR and real-time PCR to detect viral nucleic acids of A/H5N1, and were inoculated into special pathogen free (SPF) embryonated hens' eggs.
RESULTSThe pregnant woman was found to have been contacted with the sick/dead poultry directly on the 4th day before onset of illness. All the 122 close contacts were healthy after a 10-day medical observation. The major clinical features of the case were viral pneumonia with rapidly developed leukopenia and lymphopenia. The progress to acute respiratory distress syndrome and multiple organ dysfunction syndromes was found at clinical presentation. HA and NA gene of A/H5N1 virus were positive. The 8 gene fragments of A/Anhui/1/2005 (H5N1) isolated from the tracheal aspirates had not carried genes from a human virus through reassortment, and the receptor-binding site of the hemagglutinin was polybasic cleavage site.
CONCLUSIONThis was the first documented case of H5N1 infection in pregnant woman. The immunotolerant state of pregnancy might have predisposed to the fatal outcome of the patient.

To explore the drug-induced constituents of Polygonum multiflorum extract (PM). This study was the first to study the drug-induced constituents in target organ liver. Agilent MassHunter qualitative analysis software and Metabolite ID software were applied for the analysis of retention time, exact relative molecular mass, primary and secondary mass spectrum information based on ultra performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) and targeted-MS/MS. By comparison with literature and standards, a total of 5 prototypes and 6 metabolites were identified or tentatively elucidated from the liver samples. In addition, the drug-induced constituents in plasma and PM were also analyzed in this study and 8 prototypes and 19 metabolites were detected from the plasma samples, while 30 compounds were detected from the extract of PM. Emodin oxidative acetylation metabolites, hydroxyl methylation metabolites, carboxylation glucuronidation metabolites and ketone glucuronidation metabolites in this study were first reported. Through the comparative analysis between the and constituents of PM, the study preliminarily revealed the drug-induced constituents (prototypes and metabolites) in liver and clarified the transfer process and transmutation rules of constituents in PM, blood and liver, which would further deepen our understanding on constituents of PM .
