Post-hepatitis cirrhosis (PHC),which results from either hepatitis B virus (HBV) or hepatitis C virus (HCV) infection,and its associated with hemodynamic changes may cause the spleen to become functionally hyperactive-a condition known as hypersplenism.Hypersplenism is associated with anemia,leukopenia,thrombocytopenia and splenomegaly.There are several effective methods to treat hypersplenism with the development of medical technology and the main purpose is the remission of hypersplenism,reducing the portal hypertension and decreasing the risk of hemorrhage.However,complete splenectomy or partial treatment of the hyperactive spleen is still controversial all over the world.This may be caused by the lack of the knowledge on the pathophysiological characteristics and clinical significance of treating hypersplenism.This review is a comprehensive discussion on the recent research which investigates hypersplenism caused by PHC.

Objective To observe the effect of Sini decoction on inflammatory response and immune function in septic rats and to discuss its possible mechanism.Methods 66 Sprague-Dawley (SD) rats were randomly divided into normal control group (n=6),model group (n=30),and Sini decoction group (n=30).Septic model was reproduced by intraperitoneal injection of lipopolysaccharide (LPS,5 mg/kg).After the reproduction of sepsis,rats in Sini decoction group received Sini decoction (5 g/kg) by gavage,while those in model group were given equal dose of normal saline in the same way.Rats in normal control group did not receive any treatment.Blood was collected via eye sockets at 2,12,24,48,72 hours after LPS administration,then the rats were sacrificed.The concentrations of inflammatory mediators,such as interleukin (IL-1,IL-6,IL-10),tumor necrosis factor-α (TNF-α),and the expression level of monocyte human leukocyte antigen-DR (HLA-DR) were determined with enzyme linked immunosorbent assay (ELISA),and the pathological changes in intestinal mucosa were observed under electron microscope.Results The concentration of IL-1 (ng/L) at 2 hours in model group was gradually increased and peaked at 48 hours (4.07 ± 0.10),and then gradually decreased,while the IL-1 level in Sini decoction group peaked at 12 hours (2.98 ± 0.12) followed by a gradual decrease.IL-6 (ng/L) in model and Sini decoction groups peaked twice at 12 hours (91.39 ± 1.55,73.00 ± 2.38) and 48 hours (82.51 ± 1.49,64.68 ± 1.68) respectively.IL-10 (ng/L) in model group gradually decreased after peaking at 2 hours (86.66 ± 6.12),and that in Sini decoction decreased at 12 hours (71.61 ± 2.35) followed by an increasing tendency,and approached normal level at 48 hours (109.09 ±4.77 vs.124.01 ± 7.89,P＞0.05).TNF-α (ng/L) in model group was gradually increased and peaked at 48 hours (83.37 ±3.79),and that in Sini decoction peaked at 12 hours (48.52 ± 1.21),and decreased to normal level at 72 hours (18.59 ± 1.97 vs.15.50 ± 2.68,P＞0.05).During the course of the experiment,as compared with those of the model group,level of IL-1,IL-6,and TNF-α were significantly lower at all time points in Sini decoction group,and IL-10was significantly higher.The expression level of HLA-DR (μg/L) in model and Sini decoction groups peaked at 2 hours (4.86 ± 0.15,4.85 ± 0.17),and then gradually lowered.HLA-DR expression μg/L) at 48 hours and 72 hours in Sini decoction group was significantly lower than that in model group (48 hours:4.21 ± 0.12 vs.2.74 ± 0.16,72 hours:3.80 ± 0.09 vs.2.27 ± 0.12,both P＜0.01).Pathological study of intestinal mucosa showed that the intestinal mucosa were infiltrated significandy by inflammatory cells,and villi were damaged severely in both model group and Sini decoction group at 2 hours after LPS challenge.Infiltration of inflammatory cells in Sini decoction group was less intense after 12 hours,and the intestine villi repair was more obvious compared with model group.Conclusion Sini decoction could regulate systemic inflammatory response,and promote the repair of intestinal mucosa,the intestinal function and the immune status of septic rats.

Aim To explore the protective effect of lo-ganin ( an active component in Cornus officinalis ) on podocyte injury induced by advanced glycation end products ( AGEs) and its possible mechanism. Meth-ods Mouse podocytes were cultured in vitro and di-vided into Normal group, model group ( AGEs group) , loganin group and aminoguanidine group ( set as posi-tive control) . After being incubated with loganin( final concentrations are 0. 1, 1, 10 μmol · L-1 ) for 1 h, podocytes were stimulated by AGEs of 100 mg · L-1 for 24 h. Then, the cell viability was measured by u-sing MTT method. Podocytes apoptosis was evaluated by Hoechst33342/PI staining and flow cytometry. Re-ceptors of advanced glycation end products ( RAGE ) ,desmin and apoptosis-related protein like Bax, Bcl-2, cleaved caspase-3 in podocytes were detected by Western blot. Results Loganin ameliorated podocyte injury induced by AGEs, down-regulated the expression of desmin and RAGE. Loganin also reduced the apoptotic rate of podocytes and decreased the ratio of Bax/ Bcl-2 and the expression of pro-apoptotic protein cleaved caspase-3 in podocytes. Conclusion Loganin could ameliorate podocyte injury, and its mechanism may be related to the decrease of the expression of RAGE and inhibition of the apoptotic pathway.

L-1 for 24 h.Then, the cell viability was measured by using MTT method .The supernatant was extracted and the levels of NO ,ET-1,MCP-1,VCAM-1 were measured by the corresponding kits .Receptors of advanced glycation end products ( RAGE ) and NF-κB in HUVEC were detected by Western blot .Results Loganin and morroniside could inhibit HUVEC injury induced by AGEs .In model group ,the contents of ET-1,MCP-1,VCAM-1 increased(P<0.01),the content of NO decreased ( P <0.01 ) and the expression of RAGE and NF-κB increased(P<0.01); however,lo-ganin and morronside could reduce the ET-1,MCP-1, VCAM-1contents,increase the NO content and down-regulate the expression of RAGE and NF-κB to differ-ent extents .Conclusion Loganin and morroniside could ameliorate HUVEC injury , and its mechanism may be related to inhibit inflammation , the improve-ment of endothelial cell function , and the decrease of the expression of RAGE .

ObjectiveTo evaluate the protective effect of Xuebijing injection against renal injury in patients with sepsis, and to explore its possible mechanism.Methods A prospective randomized controlled trial (RCT) was conducted in which 62 severe patients with sepsis and septic shock admitted in Department of Critical Care Medicine of Jiangsu Province Traditional Chinese Medicine Hospital from June 2013 to December 2013 were randomly divided into control group and Xuebijing group, with 31 patients in each group. The patients in both groups received basic treatment for sepsis, and the patients in Xuebijing group were additionally given intravenous injection of Xuebijing 100 mL once a day for 7 days. In both groups, the changes in acute physiology and chronic health evaluationⅡ (APACHEⅡ) score were observed before treatment and 1, 3, 7 days after treatment, and the changes in the levels of interleukins (IL-6, IL-10), prothrombin time (PT), fibrinogen (Fib), activated partial thromboplastin time (APTT), serum creatinine (SCr), and Cystain C (Cys C) were determined before treatment and 1 day and 3 days after treatment.Results There was no statistically significant difference in APACHEⅡ score before treatment between two groups, however, the APACHEⅡ scores were significantly decreased in both groups 3 days and 7 days after treatment compared with those before treatment, and the degree of decrease in Xuebijing group was more obvious 7 days after treatment (13.61±7.62 vs. 16.34±8.70,P< 0.05). Serum concentrations of Cys C, SCr, IL-6, IL-10, PT, APTT, and Fib showed no difference between two groups before treatment (allP> 0.05), while after treatment the degrees of improvement of above indexes in Xuebijing group were obviously superior to those in control group, especially 3 days after treatment[Cys C (mg/L):1.12±0.11 vs. 1.35±0.14, SCr (μmol/L): 115.0±31.0 vs. 135.0±24.0, IL-6 (ng/L): 54.27±28.79 vs. 73.35±31.01,PT (s): 13.50±0.11 vs. 15.71±0.11, APTT (s): 43.66±0.31 vs. 48.03±0.55, Fib (g/L): 1.91±0.51 vs. 1.51±0.52, P< 0.05 orP< 0.01].ConclusionXuebijing injection has certain renal protective effect in patients with sepsis, and its mechanism is possibly related to the regulation and improvement of uncontrolled inflammatory response and coagulation function in sepsis.

Objective:To investigate the application value of spectral computed tomo-graphy (CT) multi-parameter imaging in predicting gastric cancer lymph node metastasis.Methods:The retrospective case-control study was conducted. The clinicopathological data of 86 patients with gastric cancer who were admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to June 2017 were collected. There were 53 males and 33 females, aged from 22 to 87 years, with a median age of 53 years. All patients received abdominal plain scan and arterial and venous phase contrast spectral scan. Images of plain scan, 70 keV monochromatic and iodine-based images in arterial and venous phase were analyzed on post-processing working station. Observation indicators: (1) gastric cancer lymph node metastasis; (2) analysis of influencing factors for lymph node metastasis in gastric cancer; (3) introduction of special cases. Count data were described as absolute numbers. Univariate analysis was performed using the chi-square test or rank sum test. Multivariate analysis was conducted using the Logistic regression model.Results:(1) Gastric cancer lymph node metastasis: of the 86 patients, 64 cases had lymph nodes metastasis and 22 had no lymph nodes metastasis. (2) Analysis of influencing factors for lymph node metastasis in gastric cancer: results of univariate analysis showed that tumor growth pattern, tumor diameter, infiltration of peritumor fat, CT value in arterial phase, CT value in venous phase, iodine value in venous phase were related factors affecting lymph nodes metastasis in gastric cancer ( χ2=6.753, Z=-3.180, χ2=7.649, Z=-2.051, -2.971, -2.547, P<0.05). Results of multivariate analysis showed that infiltration of peritumor fat and the iodine value in venous phase were greater than 12(100 μg/cm 3) and not greater than 16(100 μg/cm 3), or greater than 16(100 μg/cm 3) were independent risk factors affecting lymph nodes metastasis in gastric cancer ( odds ratio=13.154, 3.761, 7.583, 95% confidence interval as 2.597-66.620, 1.893-8.572, 4.769-16.692, P<0.05). (3) Introduction of special cases: case 1 was male, aged 46 years. Results of preoperative spectral CT enhanced scan showed gastric antrum space occupying lesion combined with enlarged lymph nodes. During enhancement arterial phase, spectral CT 70 keV monochromatic images and corresponding iodine-based images of primary lesion layer in the transverse view showed gastric wall thickening with mild to moderate enhancement, clear fat space in serosa and enlarged lymph nodes in lesser curvature. The spectral CT 70 keV monochromatic images and corresponding iodine-based images below pylorus level in the transverse view showed subpyloric enlarged lymph nodes. During enhancement venous phase, the 70 keV monochromatic images and corresponding iodine-based images of primary lesion layer in the transverse view showed layered enhancement of gastric antrum lesions and mucosal enhancement, with a high iodine value. The patient was diagnosed as gastric antrum cancer with lymph node metastasis, no serosal or peritumoral fat invasion. Results of postoperative pathological examination showed moderately differentiated adenocarcinoma of gastric antrum with serosal invasion and lymph node metastasis. Case 2 was male, aged 53 years. Results of preoperative spectral CT enhanced scan showed gastric cancer of lesser curvature combined with enlarged lymph nodes. During enhancement arterial phase, 70 keV monochromatic images and corresponding iodine-based images of primary lesion layer in the transverse view showed gastric wall heterogeneous thickening of lesser curvature, with moderate enhancement, obscure peritumor fat space, unclear serosa, and multiple enlarged lymph nodes in lesser curvature. During enhancement venous phase, 70 keV monochromatic images in the transverse view showed unclear boundary between lesions and enlarged lymph nodes in lesser curvature, obscure peritumor fat. During enhancement arterial phase, 70 keV monochromatic images of celiac trunk layer in the transverse view showed parasplenic artery lymph nodes, with circular enhancement and no enhancement in central necrotic elements. The patient was diagnosed as gastric cancer of lesser curvature with lymph node metastasis, serosal and peritumor fat invasion. Results of postoperative pathological examination showed poorly differentiated adenocarcinoma of gastric antrum with serosal invasion and lymph node metastasis. Conclusion:The infiltration of peritumor fat and iodine value in venous phase are independent factors affecting gastric cancer lymph node metastasis.

Objective To assess the effectiveness of a novel mobile health patient management system involving doctors, nurses, and patients ( TRIO mode) on glycemic control and self-monitoring of blood glucose (SMBG) compliance among the type 2 diabetes mellitus ( T2DM) patients using basal insulin standardization treatment in China. Methods From April 2014 to April 2015, 416 hospitals in 110 cities of 30 provinces, municipalities, and autonomous regions across China were selected to participate in the program. A Online-to-Offline ( O2O) integrated mobile health patients management system with mobile terminals for the doctors, nurses, and patients was applied in the program for patient education, follow-up, and data collection. For all the newly recruited patients, the baseline information was collected and a first-day patient education program were provided by a designated nurse. In the 12-week follow-up period, data of basal insulin doses and fasting plasma glucose ( FPG) values were collected from the patients by text messages or tracking phone call by the nurse. The patients also received timely standardized patients health education and glycemic control guidance by participating in thepatient education forum anddoctors' hotline in order to help them achieve the glycemic control goals. Results A total of 102 524 patients using basal insulin treatment were eligible and enrolled in the program. 64 420 patients completed the 12 weeks follow-up and provided at least one FPG value at all five follow-ups. In total, 62. 6% (40 334 / 64 420) of the patients reached the FPG control target(FPG≤7. 0 mmol/ L) at the end of follow-up period. The weekly average FPG for patients with complete SMBG data decreased from 10. 58 mmol/ L to 6. 91 mmol/ L while the FPG control rates increased from 13. 4% to 69. 2% . The weekly average FPG for the patients provided incomplete SMBG data decreased from 10. 54 mmol/ L to 7. 13 mmol/ L while the FPG control rates increased from 13. 6% to 62. 2% . The FPG control rates for the patients provided complete SMBG were 1. 74 times higher than those patients provided incomplete SMBG. Based on a GEE model, the average decline of the FPG and the increase of the FPG control rates were significantly better for patients who provided complete SMBG as compared to the patients with incomplete SMBG data. The results of the multivariate logistic regression analysis showed that factors such as receiving the first-day education, participating in the follow-up patient education forum, and the doctors' hotline were significantly associated with the improvement of the SMBG compliance, the treatment adherence, and the FPG control rates. The SMBG compliance and the treatment adherence for patients who completed first-day education were 1. 68 times and 1. 22 times higher, respectively. For the patients who participated in follow-up education activities, their SMBG compliance and treatment adherence were 3. 17 times and 3. 36 times higher, respectively. Conclusion The innovativeTRIOmobile health patient management mode was feasible and effective for better managing the type 2 diabetes patients initiated on basal insulin treatment in China. Active participation in the first-day education program and the follow-up patient education activities can effectively improve the SMBG compliance and the treatment adherence, and therefore play an important role in helping patient achieving FPG control in a faster manner.

OBJECTIVETo investigate the preoperative assessment value of spectral CT quantitative parameters in lymph node metastasis of gastric cancer.

METHODSFrom December 2013 to June 2015, clinical and image data of 86 patients with gastric cancer confirmed by gastroscope pathology undergoing preoperative enhanced CT were prospectively collected. Enhanced CT included nonenhanced CT of conventional 120 kVp mode, arterial phase (AP) and venous phase (VP) with GSI mode on Discover GSI CT scanner. The raw data were transferred to ADW4.6 workstation to reconstruct the monochromatic images at 70 keV and iodine-based images in AP and VP with 1.25 mm thickness. The short diameter, long diameter, ratio of short to long diameter, CT attenuation and iodine value of lymph nodes in each phase were measured and recorded. Pathology results were used as golden standard. The spectral CT quantitative parameters of positive and negative lymph nodes were compared by t test and the sensitivity and specificity analyses were performed by ROC curves. This clinical study registration number 81271573.

RESULTSAmong these 86 gastric cancer patients (53 male and 33 female), tumors of 28 cases were in upper part, of 12 cases in middle part, of 27 cases in distal part and of 19 cases involved two parts. Thirty-five cases were differentiated type and 51 cases were undifferentiated type. A total of 1 072 lymph nodes were found in operation, of which 412 nodes were positive and 660 were negative. Among 552 lymph nodes found in CT images, 338 nodes were positive and 214 were negative. Compared to negative lymph nodes, short diameter [(9.52±3.58) mm vs. (6.48±2.94) mm, t=4.639, P=0.000], ratio of short to long diameter (0.82±0.14 vs. 0.61±0.08, t=13.514, P=0.000), CT attenuation in precontrast [(20.44±6.77) Hu vs. (16.06±7.14) Hu, t=3.154, P=0.002], CT attenuation in AP[(61.71±11.78) Hu vs. (40.11±10.18) Hu, t=9.588, P=0.000], CT attenuation in VP[(71.34±13.03) Hu vs. (53.81±11.39) Hu, t=7.888, P=0.000], iodine value in AP [(16.17±4.22) 100 μg/cmvs. (8.03±3.10) 100 μg/cm, t=9.781, P=0.000], the iodine value in VP [(20.13±6.04) 100 μg/cmvs. (11.58±4.13) 100 μg/cm, t=10.147, P=0.000] of positive lymph nodes were greater. The long diameter was not significantly different between positive and negative lymph nodes [(11.71±5.63) mm vs. (10.64±3.20) mm, t=1.380, P=0.169]. The area under ROC curve of short diameter, ratio of short to long diameter, CT attenuation in precontrast, AP and VP, iodine value in AP and VP of lymph nodes was 0.600, 0.880, 0.648, 0.832, 0.755, 0.864, 0.835, respectively. Taking the ratio of short to long diameter over 0.72 as diagnosis standard, the sensitivity was 75.6% and the specificity was 93.5%. Taking the CT number in AP over 49.75 Hu, the sensitivity was 66.9% and the specificity was 88.8%. Taking the CT number in VP over 59.80 Hu, the sensitivity was 69.9% and the specificity was 77.6%. Taking the iodine value in AP over 9.65 (100 μg/cm), the sensitivity was 80.4% and the specificity was 82.2%. Taking the iodine value in VP over 15.65 (100 μg/cm), the sensitivity was 69.9% and the specificity was 86.9%. Combinong the ratio of short to long diameter with the iodine value in AP, the sensitivity was 95.2% and the specificity was 76.9%.

CONCLUSIONSThe ratio of short to long diameter, the iodine value and CT attenuation in AP and VP of lymph nodes in spectral CT are important criteria to evaluate the metastasis of gastric cancer. Combining the ratio of short to long diameter with the iodine value in AP can obviously improve the sensitivity.
