Objective To analyze the differences in urinary stone components between Uyghur and Han patients with urolithiasis in Xinjiang,and to explore the related factors contributing to the observed differences.Methods The data of urinary stone compo-nents in 317 adult patients with urolithiasis (152 cases of Uyghur nationality and 165 cases of Han nationality)admitted to Xinjiang Uygur Autonomous Region People′s Hospital from June 2009 to June 2011 were retrospectively analyzed.The urinary stone compo-nents were analyzed by the infrared spectroscopy.Results There were significant differences in thestone component proportions of calcium oxalate monohydrate (COD),COD+carbapatite (CA)and uric acid (UA)between Uyghur and Han patients(P <0.05). Conclusion The characteristics of the urinary stone comppnents have significant differences between Uyghur and Han patients with urolithiasis,which may be related with ethnicity and the different dietary habits.

OBJECTIVETo investigate the value of neutrophil-monocyte product (NMP) combined with serum creatinine (Scr) in the assessment of the severity of acute pancreatitis (AP).

METHODSThe clinical data of 120 Uighur patients with AP were retrospectively analyzed, including 104 with non-severe AP (non-SAP group) and 16 with severe AP (SAP group). The correlation of NMP combined with Scr with ICU admission and in-hospital death were analyzed. The receiver operating characteristic (ROC) curves were plotted to compare the efficiency of acute physiology and chronic health evaluation (APACHE-II), neutrophil-lymphocyte ratio (NLR) and NMP combined with Scr in determining the severity of AP.

RESULTSThe levels of NMP and Scr were significantly higher in SAP group than in non-SAP group within 24 h after admission (P=0.012; P<0.001). NMP combined with Scr was positively correlated with ICU admission (r=0.489, P<0.001) and in-hospital death (r=0.383, P<0.001). No significant difference was found in the area under curve (AUC) between APACHE-II and NMP combined with Scr for determining AP severity (Z=0.38, P=0.704), but they both were superior to NLR (Z=3.10, P=0.002; Z=2.43, P=0.016).

CONCLUSIONNMP combined with Scr can be a simple and effective indicator for determining the severity of AP.

Objective To determine the status of glycemic control in type 2 diabetic patients in Jiangsu province. Methods Survey was conducted among outpatients with type 2 diabetes mellitus from 56 diabetes centers including 23 tertiary hospitals, 18 secondary hospitals and 15 primary hospitals, covering 13 cities in Jiangsu province. Data were obtained by patient interview and by reviewing medical records of the most recent laboratory assessment and clinical examinations. Blood samples were collected during patient′s visits for assessment of HbA1C. Results The mean HbA1Cof 2 966 patients was 7.18%±1.58%. Mean age of patients was(56.4±11.2) years, mean duration of diabetes was(6.3±5.7) years, and mean body mass index was(24.5±3.3) kg/m2. The proportion of good control was 40.2% defined as HbA1C＜6.5%. 42.2% of the patients in the tertiary hospitals, 36.5% of the cases in the secondary hospitals, and 36.2% of cases in the primary hospitals achieved that goal with HbA1C＜6.5%, while age, body mass index, and duration of diabetes revealed no difference among these 3 groups of patients. Conclusions The status of glycemic control in Jiangsu province has been improved as compared with the result from national survey performed 3 years ago. Patients from tertiary hospitals are better controlled than those from secondary and primary hospitals. Structural interventions to improve diabetes care in secondary and primary hospitals are needed.

Objective To investigate the expression of NADPH oxidase Nox-4 induced by stress in gastric mucosa and its role in inflammation.Methods Twenty male SPF Kunming mice were randomly divided into chronic restraint stress group(stress group) and control group.Stress mice were restrained in selfmade restraint device for 2 hours each day.The rest of the time,the mice in the two groups had free access to food and water normally,experiment lasted 14 days.The histopathological changes of gastric mucosa were assessed by HE staining under light microscope.The expression of Nox-4 in gastric mucosa of mice was carried out by immunohistochemical method.The relative expression levels of Nox-4,antioxidant protein (Mn-SOD,GSH,Catalase) and inflammatory factors(IL-8,IL-1β,TNF-α) in gastric mucosa were detected by real-time quantitative RT-PCR and ELISA.Results Basal cell proliferation,neutrophil,eosinophil and plasma cell infiltration and inflammatory changes were observed in the lamina propria and glandular epithelium of stress mice,while no obvious abnormalities were found in control mice.The expression of Nox-4 in stress group was deeper and more abundant than that in control group,mainly expressed in lamina propria and glandular epithelium.The mRNA expression levels of Nox-4 in gastric mucosa of stress group was(2.42±0.51) times higher than that of control group,and blood concentration of stress group was(2.23±0.67) times higher than that of control group(t=-46.32,P＜0.001).The RT-PCR of antioxidant proteins in gastric mucosa showed that the transcription levels of Mn SOD,GSH and Catalase in stress group were significantly lower than that of control group (Mn-SOD:0.59± 0.10,GSH:0.58± 0.11,Catalase:0.57± 0.09),and there were significant differences between the two groups(t=13.57,11.67,15.01,P＜0.01).RT-PCR results showed that the transcription levels of IL-8,IL-1β,TNF-α in stress group were significantly higher than those in control group (IL-8:1.47±0.34,IL-1β:1.48 ± 0.42,TNF-α:1.51 ± 0.37),and there were significant differences in two groups(t=-18.45,-19.14,-20.85,P＜0.01).ELISA results showed that the serum levels of inflammatory factors in stress group were significantly higher than those in control group(2.25±0.37,3.59±0.45,3.41±0.34),and the differences were statistically significant(t=-47.11,-79.36,-96.32,P＜0.01).Pearson correlation analysis showed that there was a positive correlation between serum concentration of Nox-4 and inflammatory factors(IL-8,IL-1β,TNF-αt) in stress group(r=0.97,0.99,0.98,P＜0.01).Spearman rank correlation analysis showed that the grade of gastric mucosal inflammation was positively correted with serum levels of Nox-4 and inflammatory factors (IL-8,IL-1β,TNF-α) (r =0.96,0.92,0.91,0.94,all P＜ 0.01)Conclusion Stress may lead to gastric mucosal lesion by overexpression of proinflammatory factors through destroying the balance of oxidation/antioxidant system in gastric mucosa.

Objective To explore the clinical and laboratory characteristics of chronic B lymphocyte proliferation disease (B-CLPD) without typical lymphoid proliferation. Methods The clinical records of patients with B-CLPD only characterized by pancytopenia form January 2007 to March 2016 in hematology department of Xinjiang Uygur Autonomous Region People ' s Hospital were collected, and the cell morphology, bone marrow pathology, cytogenetics and molecular characteristics were retrospectively analyzed. Results The median age of 11 patients was 68 years old. The lymphocyte ratio of peripheral blood smears in all patients increased in different level (0.36-0.68), but absolute lymphocyte count was normal or decreased (0.59×109-1.99×109). Lymphocyte-like plasma cell or small numbers of plasma cell can be seen in the bone marrow smears of 4 cases and lymphocytes with irregular burr-like protrusions were observed in 2 cases while there were no characteristic morphological changes in remained 5 cases. Immunophenotypical analysis showed that all patients expressed CD19, CD20, CD22, SmIg, not expressed CD5, CD10 which with scores of 0-2 according to chronic lymphocytic leukemia (CLL) points system;CD103, CD11C, CD25 and FMC7 were highly expressed in 2 cases while there were no characteristic expression in remaining cases. There were no abnormal karyotypes observed from the conventional cytogenetic and fluorescence in situ hybridization (FISH) analysis (both of IgH/CCND1, bcl-2/IgH were negative) in all patients. 8 patients were found IgH gene rearrangement, MYD88L256P and BRAF V600E was positive in 5 cases and 2 cases respectively. 5 cases were diagnosed as Waldenstrom macroglobulinemia, 3 cases were B-CLPD, 2 cases were hairy cell leukemia, 1 case was nodal marginal zone B-cell lymphoma after comprehensive analysis of their clinical and laboratory data. Conclusion Even if there are no increased peripheral blood lymphocytes in pancytopenia patients, it is necessary to perform bone marrow smears, immunophenotyping, IgH gene rearrangement, cytogenetics and other molecular laboratory tests to exclude B-CLPD, and reduce misdiagnosis.

Objective To investigate the expression of malondialdehyde ( MDA) in esophageal mu-cosa of different types of gastroesophageal reflux disease ( GERD) patients and its role in the esophageal in-flammation. Methods According to the inclusion and exclusion criteria, 42 patients hospitalized in the the Xinjiang Uygur Autonomous Region People's Hospital from December 2017 to October 2018 were selected as the research group. 8 healthy subjects completed physical examination were set up as healthy control group. GERD completed GERDQ score, 24 h pH monitoring, and taken 3 cm on the dentate line of the esophagus as a specimen. The study group was divided into non-erosive reflux disease (NERD) group (17 cases) and Ero-sive reflux disease [erosive esophagitis (RE)] group (25 cases). Then hematoxylin-eosin (HE) staining, immunohistochemistry, real-time polymerase chain reaction ( qPCR ) , enzyme-linked immunosorbent assay (ELISA) methods were used to detect inflammation, oxidative stress (MDA), antioxidant enzyme [manga-nese superoxide dismutase (Mn SOD), glutathione (GSH), catalase (CAT)], and proinflammatory cyto-kines [monocyte chemotactic protein-1 (MCP-1), interlukin-8 (IL-8), tumor necrosis factorα(TNF-α)]. Results There was no significant difference in body mass index ( BMI ) between the three groups ( P >0. 05). 24 h pH monitoring of esophagus showed that the indexes of weak acid reflux (40. 05). In RE group , the infiltration of immune cells (neutrophils, eosinophils), nipple lengthening, edema and other inflammatory changes were found in the esophageal mucosa, and the inflammation score reached the peak, which was signif-icantly higher than that in NERD group, with statistical significant difference (P<0. 001). The positive ex-pression of MDA in the two groups ( NERD, RE) was higher than that in the control group, and the MDA ex-pression in the RE group was almost covered with the full layer esophagus. The serum MDA concentration in the NERD and RE groups was significantly higher than that in the control group (P<0. 001). Compared with the NERD group, the serum MDA in the RE group reached the peak (P<0. 01). The relative expression of mRNA ( Mn SOD, GSH and CAT) in NERD group and RE group was significantly decreased, and there was a significant difference between the three groups (P<0. 001). Compared with the NERD group, the mRNA expression level of Mn SOD and CAT in RE group was significantly decreased (P<0. 01). The relative ex-pression of mRNA (MCP-1, IL-8, TNF- α) increased significantly in the two groups (NERD, RE), and there was a statistically significant difference between the three groups ( P <0. 001 ) . Compared with the NERD group, the expression of its inflammatory factors in the RE group significantly increased (P<0. 01). Conclusions The expression level of MDA in different types of GERD is significantly higher, which may be closely related to esophageal inflammation induced by acid reflux.

Objective To investigate stress induced Nox-4 expression and to explore its role in adipose inflammation. Methods Twenty male Kunming mice were randomly divided into two groups ( n=10 each) , chronic restraint stress group and control group. Stress mice were restrained in self-made restraint device for 2 hours per day for 14 days. HE staining, immunohistochemistry, RT-PCR, and ELISA were used to analyze the expression of Nox-4, CD11b, antioxidant protein ( Mn SOD, GSH-Px, Catalase), adipocytokines ( adiponectin, MCP-1, IL-6, TNF-a). Results White adipose tissue (WAT) of stress mice inguinal fat pad significantly shrank compared to control group. HE staining showed that there were a large number of mononuclear cells, neutrophils, eosinophils, and cell infiltration reactions and inflammatory changes in WAT of stress mice. The stress significantly increased CD11b-positive cells and the expression of mF4/80, CD68. The concentration of serum FFA in stress group increased significantly, nearly twice of the control group ( P<0.01) . Nox-4 positive staining cells in stress WAT were deeper and more abundant. The level of Nox-4 in stress WAT was significantly higher than that of control group(P<0.01). The levels of antioxidant proteins such as Mn-SOD, GSH-Px, and catalase in stress WAT were significantly lower than those of control group (P<0.01). The expression levels of adiponectin in stress WAT were significantly reduced as compared to control group ( P<0.01) . The levels of MCP-1, IL-6 and TNF-α in stress WAT were significantly higher than those in control group (P<0.01). Conclusion Stress may lead to imbalance of adipose oxidation/antioxidant system and abnormal expression of adipocytokines, which may result in adipose inflammation.

Objective:To investigate the chronic restraint stress induced expressions of acid sensitive receptors and its role in the esophageal inflammation and oxidative stress.Methods:Twenty male specific pathogen free (SPF) Kunming mice were randomly divided into two groups: stress group and control group (each group, n=10). Stress mice were restrained in self-made restraint device for 2 hours per day and lasted for total 14 days. The histopathological changes of esophageal mucosa were observed by hematoxylin eosin (HE) staining under light microscope. The expression of nicotinamide adenine dinucleotide phosphate (Nox-4) was detected by immunohistochemistry, real time fluorescent quantitative polymerase chain reaction (qRT-PCR) and enzyme linked immunosorbent assay (ELISA). The mRNA expressions of acid sensitive receptors were detected by qRT-PCR. Results:HE staining showed that stress mice had obvious infiltrations of neutrophils and eosinophils, and also showed inflammatory change in esophgus, while no significant abnormality was found in the esophagus of control mice. The inflammotory scores in stress group were significantly higher than that in control group ( P<0.001). Immunohistochemistry showed that Nox-4 was mainly expressed in the lamina propria, mucosa and submucosa of esophagus. The mRNA expression levels of Nox-4 in stress group was (2.67±0.62) times higher than control group, with statistically significant difference ( P<0.001). In addition, the plasma concentration of Nox-4 in stress group was significantly higher than that of control group [(0.42±0.01)ng/ml vs (2.13±0.35)ng/ml, P<0.001]. The transcription levels of acid sensitive receptors in stressed mice, such as transient receptor potential vanilloid-1 (TRPV-1), TRPV-4, acid-sensing ion channel-1 (ASIC-1), ASIC-2 and ASIC-3 were significantly higher than those in the control group, with statistically significant difference ( P<0.001). Pearson correlation analysis showed that there was a positive correlation between Nox-4 mRNA expression and TRPV-1, TRPV-4, ASIC-1, ASIC-2, ASIC-3 mRNA expression in stress group ( r=0.97, 0.94, 0.98, 0.95 and 0.99, P<0.01). Conclusions:Stress may increases the expression of acid sensitive receptors and result in an esophageal inflammation and oxidative stress, which may contribute to the formation of esophageal hypersensitivity.

Objective:To investigate the anti-inflammatory effects of water extract of the Iris halophila root on lipopolysaccharide（LPS） stimulated RAW264.7 cells and analyze its chemical constituents. Method:The supernatant of YWG prepared by water extraction and alcohol precipitation was separated by AB-8 macroporous adsorption resin column chromatography to obtain ethanol eluates with different concentrations （YWG，YWG-0%，YWG-20%，YWG-40%，and YWG-60%）. Cell counting kit-8（CCK-8） assay was used to determine the effects of YWG-0%，YWG-20%，YWG-40%，and YWG-60% on the viability of RAW264.7 cells. Griess assay was employed to detect the nitric oxide （NO） level in LPS-stimulated RAW264.7 cells. The release of tumor necrosis factor（TNF）-α，interleukin（IL）-6，IL-10，and IL-1β was detected by enzyme-linked immunosorbent assay（ELISA）. YWG and the elution site with the most robust anti-inflammatory activity were identified and compared by ultra-high performance liquid chromatography-quadrupole-time of flight-mass spectrometry （UHPLC-Q-TOF-MS/MS）. Result:Ethanol eluates with different concentrations inhibited the release of NO，TNF-α，IL-1β， and IL-6 in the supernatant of LPS induced RAW264.7 cells （P<0.05），and promoted the release of IL-10 （P<0.05）. YWG-60% displayed a highly significant effect （P<0.01）. A total of 127 constituents were detected from the comparison of YWG and YWG-60% by UHPLC-Q-TOF-MS/MS in the positive and negative ion modes，including 61 flavonoids. YWG-60% contained 25 flavonoids with elevated content as compared with YWG. Conclusion:YWG-60% showed potent anti-inflammatory effect，and the effective anti-inflammatory constituents were presumedly flavonoids. The findings of this study are expected to provide a scientific theoretical basis for the basic research on the medicinal effect of the water extract of YWG.
