Objective To investigate the difference of apparent diffusion coefficients (ADCs) changes in three major salivary glands after gustatory stimulation using two different stimuli. Methods Thirty healthy volunteers were examined with a 1.5 T MR unit. A diffusion-weighted MR imaging (MR DWI) sequence was performed once at rest and continuously repeated 13 times after gustatory stimulation using a commercially available lemon juice and vitamin C tablets in the same volunteer by using self-controlled method. The subsequence of two stimuli was random. In addition, the salivary flow rates at rest and after stimulation were measured. Characteristics and differences in ADCs curves of three salivary glands before and after stimulation between two stimuli were analyzed. Comparison of maximum ADCs, maximum ADCs increase rates (IRs) and times to maximum ADCs(Tmax) between two stimuli was performed by using independent-samples t test. Correlation analysis between rest salivary flow rates and rest ADCs, the maximum salivary flow rates and ADCs after stimulation, the maximum salivary flow IRs and ADC IRs after stimulation were performed by using Pearson correlation test. Results In lemon juice stimulation group, the mean ADCs mostly showed a steady increase to peak values during the first DW MRI scan after stimulation in all glands, followed by a gradually decrease fluctuating slightly around the baseline values. In vitamin C stimulation group, the mean ADCs were significantly increased in all glands during the first DW MRI scan after stimulation, followed by a gradual upward trend till peak values. In lemon juice stimulation group, the mean Tmax of submandibular and sublingual glands[(184±122)s, (345±232)s, respectively] were significantly earlier than those[(454 ± 301)s, (528 ± 297)s, respectively] in vitamin C stimulation group (t=-3.517 and-2.548 respectively, P<0.01 for all). The mean maximum ADCs of three glands in lemon juice stimulation group[(1.05 ± 0.12) × 10-3 mm2/s, (1.22 ± 0.10) × 10-3 mm2/s and (1.26 ± 0.21) × 10-3 mm2/s, respectively] were all lower than those in vitamin C stimulation group[(1.13±0.13) ×10-3 mm2/s, (1.32±0.25) × 10-3 mm2/s and (1.57 ± 0.36) × 10-3 mm2/s, respectively], and the differences in parotid and sublingual glands between two groups were significant(t=-2.894 and-3.681 respectively, P<0.01 for all). The mean maximum ADC IRs of three glands in lemon juice stimulation group[(11.35±4.07)%, (8.81±5.40)%, (34.08±21.66)%, respectively] were significantly lower than those[(17.80 ± 12.72)%, (18.16 ± 18.93)%, (67.49 ± 46.04)% , respectively] in vitamin C stimulation group (t=-2.252,-2.330 and-3.432 respectively, P<0.05 for all) . In two groups, the mean maximum ADC IRs of parotid and submandibular gland were all significantly lower than sublingual gland (t=-5.994 and-6.443 respectively, P<0.01 for all). No correlation was observed between ADCs and salivary flow rates, ADC IRs and salivary flow rate IRs in two groups (P>0.05). Conclusion MR DWI with transient stimulation using lemon juice is more stable for evaluating the physiologic changes of salivary glands in vivo.

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

OBJECTIVEFrom the end of 1990s, ambulatory blood pressure monitoring (ABPM), which measures ambulatory blood pressure (ABP) during a whole 24 hours, has been applied. However, there are few studies on the use of ABPM in children with kidney disease, especially those whose renal function is normal or mildly impaired in both China and abroad. This study aimed to explore the characteristics of ABP in patients with common pediatric kidney diseases.
METHODSTotally 33 patients (21 boys and 12 girls) hospitalized in our hospital with kidney diseases aged from 5 - 16 yrs from February 2005 to January 2006 were enrolled; 28 cases (85%) had normal renal function [Ccr > or = 90 mmol/(Lx1.73 m2)]. None of them were taking anti-hypertensive drugs during the monitoring. Twenty-four-hour ABP monitoring was performed by using Welch Allyn ABPM 6100 in the patients. ABPM recordings of 1141 healthy children performed in Germany in 1997 was used as the normal reference data, which was the largest pediatric study and was most commonly used in the world up to now.
RESULTSThe incidence of nocturnal hypertension was significantly higher than that of diurnal hypertension (P < 0.01); nocturnal systolic/diastolic blood pressure load (29.1 +/- 34.5)%/(24.9 +/- 34.3)% and index (0.95 +/- 0.11)/(0.90 +/- 0.18) were significantly higher than diurnal systolic/diastolic blood pressure load (12.9 +/- 23.6%/9.3 +/- 19.1%) and index (0.88 +/- 0.09)/(0.77 +/- 0.12) (P < 0.01); nocturnal systolic/diastolic dipping rate (7.3 +/- 5.3)%/(10.5 +/- 10.6)% in the patients was significantly lower than that in the healthy children (13 +/- 6)%/(23 +/- 9)% (P < 0.01); the incidence of non-dipper in 33 patients was 72.7%, even with the same incidence in patients with normal blood pressure. Five cases had elevated CBP whose ABP were also elevated; while among the 28 cases with normal CBP, 6 cases were found to have elevated ABP.
CONCLUSIONSABPM can detect the nocturnal hypertension and abnormal rhythm of blood pressure during 24-hour in patients with pediatric nephropathy. ABPM can also disclose masked hypertension, thereby warrant to follow-up and start earlier intervention.

Horseshoe kidney and retrocaval ureter are uncommon congenital anomalies of the genitourinary system that are easily diagnosed by typical imaging features. Both anomalies presenting in one patient is a rare disease characterized by isthmus of horseshoe kidney between the abdominal aorta and inferior vena cava. The clinical diagnosis and treatment of horseshoe kidney with retrocaval ureter remain a challenge. Here, we reported a case of a 44-year-old man with the two anomalies who was preoperatively diagnosed by unenhanced computed tomography scanning immediately after retrograde pyelography. The literatures on such combined anomalies are reviewed and the diagnostic evaluation and surgical management of this rare entity are discussed.

Objective To investigate the effect of thymosin ?1 (T?1) on cellular immune function in gastric cancer patients through observing its treatment on the differentiation of T-lymphocyte subsets from screened peripheral blood mononuclear cells (PBMCs). Methods PBMCs were obtained by centrifugation of blood samples from 18 healthy subjects and 32 patients with gastric cancer,and then cultured in the presence of culture medium with addition of T?1 at 50,10 and 1 ?g/ml for 2 d. T lymphocyte subsets (such as CD4+,CD8+ and CD4+ CD25+ Foxp3+ T cells) and Th1/Th2 multiplex cytokines were detected by flow cytometry (FCM). Results After PBMCs isolated from healthy people and patients were incubated with or without T?1,there was no significant change in percentage of CD4+,CD8+ peripheral lymphocyte subsets and ratio of CD4+/CD8+. There was no obvious change in the percentage of CD4+ CD25+ Foxp3+ T lymphocyte subsets in the normal control,but a significant increase was observed in the cells from patients with gastric cancer after treatment (P

Objective To investigate the function of JAK2-STAT3 signaling pathway in pancreatic injury and systematic inflammatory response in rats with acute necrotizing pancreatitis ( ANP) . Methods SD rats were randomly divided into the ANP group (n=48), ANP+JAK2 inhibitor Ruxolitinib group (ANP+R group, n=48), ANP+STAT3 inhibitot Stattic group (ANP+S group, n=48), ANP+Ruxolitinib+Stattic group (ANP+R+S group, n=48), and sham operation group (SO group, n=48). 5% sodium taurocholate injection via retrograde pancreatobiliary duct was used to establish ANP model. Blood samples from abdominal aorta and pancreatic tissue were collected after 3 h, 6 h, 12 h and 18 h after modeling. Serum amylase (AMY) and tumor necrosis factor-α(TNF-α) and interleukin-4 (IL-4) were tested. JAK2 and STAT3 mRNA expression and protein expression of p-JAK2 and p-STAT3 in pancreas were examined by RT qPCR and western blot, respectively. Results AMY, TNF-α and IL-4 in plasma, and JAK2 mRNA, STAT3 mRNA, p-JAK2 protein and p-STAT3 protein at different time points in ANP group were all obviously higher than those in SO group(P<0. 05). Serum AMY, TNF-αand IL-4 in ANP+R group, ANP+S group and ANP+R+S group at different time points were lower than those in ANP group [12 h (5391 ± 1009),(6130 ± 1227),(4818 ± 992)U/L vs (8524 ± 1360) U/L;(147.25 ± 27.85),(156.25 ± 23.17),(127.87 ± 21.39) ng/L vs (187.58 ±20.09)ng/L;(45.89 ±16.95),(50.19 ±15.87),(38.87 ±14.03)ng/L vs (58.85 ±9.34)ng/L] . JAK2 mRNA and p-JAK2 protein,STAT3 mRNA and p-STAT3 protein in ANP+R group and ANP+R+S group at different time points were obviously lower than those in ANP group (12 h 0. 357 ± 0. 091 vs 0. 597 ± 0. 121,1. 115 ± 0. 203 vs 1. 217 ± 0. 213,0. 361 ± 0. 089 vs 0. 489 ± 0. 097,0. 965 ± 0. 189 vs 1. 128 ± 0. 217, 0. 362 ± 0. 092 vs 0. 597 ± 0. 121,1. 107 ± 0. 212 vs 1. 217 ± 0. 213,0. 297 ± 0. 087 vs 0. 489 ± 0. 097,0. 713 ± 0. 184 vs 1. 128 ± 0. 217). STAT3 mRNA and p-STAT3 protein in ANP+S group were obviously lower than those in ANP group(0. 319 ± 0. 107 vs 0. 489 ± 0. 097,0. 849 ± 0. 177 vs 1. 128 ± 0. 217), and the difference was statistically different (P<0.05). Conclusions The activation of JAK2-STAT3 signaling pathway in pancreas may play a key role in the pathogenesis of systematic inflammatory response in ANP.
