Objective:To investigate the serum level of fatty acid binding protein 1 (FABP1) and its relationship with Helicobacter pylori (Hp) infection in patients with gastric cancer. Methods:Forty gastric cancer patients (gastric cancer group) who were hospitalized in Affiliated Hospital of Qinghai University from August 2021 to August 2022 were selected as the research subjects, and 40 physical examination subjects during the same period were selected as the normal control group and 40 chronic atrophic gastritis patients were selected as the CAG group. The Hp infection were detected by 13C breath test, and the levels of serum FABP1 were detected by enzyme-linked immunosorbent assay. The Hp infection status, serum FABP1 levels, and the relationship between the two in the three groups of study subjects were analyzed. And the relationships between the level of serum FABP1 and the clinicopathological features of gastric cancer patients were analyzed. The diagnostic value of serum FABP1, CA19-9, CA72-4 and combined test of 3 indexes were evaluated by receiver operating characteristic (ROC) curve. Results:The Hp infection rates in the control group, CAG group, and gastric cancer group were 32.50% (13/40), 55.00% (22/40), and 60.00% (24/40), respectively, with a statistically significant difference ( χ2=6.87, P=0.032). Among them, the Hp infection rate in the control group was compared with that in the gastric cancer group, with a statistically significant difference ( P<0.05), and there were no statistically significant differences between the CAG group and the control group, the gastric cancer group (both P>0.05). The levels of serum FABP1 in the control group, CAG group, and gastric cancer group were [63.47 (37.53, 71.59) ] ng/ml, [65.26 (51.15, 79.67) ] ng/ml, and [72.84 (53.44, 82.25) ] ng/ml, respectively, with a statistically significant difference ( H=6.62, P=0.037). Among them, there was a statistically significant difference between the control group and the gastric cancer group ( H=19.93, P=0.031), while there were no statistically significant differences between the CAG group and the control group, the gastric cancer group ( H=1.50, P=0.133; H=1.09, P=0.277). Among all study subjects, the levels of serum FABP1 in the Hp positive group ( n=59) and Hp negative group ( n=61) were [77.05 (68.90, 83.54) ] ng/ml and [47.80 (37.76, 63.32) ] ng/ml, respectively, with a statistically significant difference ( Z=7.45, P<0.001). In the control group, the levels of FABP1 in the serum of Hp positive and Hp negative persons were [77.34 (68.84, 86.31) ] ng/ml and [39.79 (36.83, 63.75) ] ng/ml, respectively, with a statistically significant difference ( Z=4.46, P<0.001). In the CAG group, the levels of FABP1 in the serum of Hp positive and Hp negative patients were [76.51 (65.30, 80.97) ] ng/ml and [49.34 (39.92, 59.41) ] ng/ml, respectively, with a statistically significant difference ( Z=4.32, P<0.001). In the gastric cancer group, the levels of FABP1 in the serum of Hp positive and Hp negative patients were [77.15 (72.62, 84.13) ] ng/ml and [50.57 (44.54, 68.97) ] ng/ml, respectively, with a statistically significant difference ( Z=4.32, P<0.001). There were significant correlations between the serum level of FABP1 and smoking ( t=2.54, P=0.015), tumor diameter ( t=2.23, P=0.035), and lymph node metastasis ( t=3.22, P=0.003) in gastric cancer patients. And there were no significant correlations between FABP1 and gender ( t=0.98, P=0.333), age ( t=1.60, P=0.117), alcohol consumption ( Z=0.10, P=0.925), tumor site ( F=1.06, P=0.356), degree of differentiation ( t=0.61, P=0.545), the depth of infiltration ( t=1.41, P=0.166), distant metastasis ( Z=1.96, P=0.050) and TNM staging ( Z=0.66, P=0.508). ROC curve analysis showed that the area under the curve (AUC) of serum FABP1 for gastric cancer diagnosis was 0.62, 95% CI: 0.51-0.72, the sensitivity and specificity were 57.50% and 68.70%, respectively; the AUC of CA19-9 for gastric cancer diagnosis was 0.89, 95% CI: 0.83-0.95, the sensitivity and specificity were 77.50%, 86.30%, respectively; the AUC of CA72-4 for gastric cancer diagnosis was 0.88, 95% CI: 0.81-0.94, the sensitivity and specificity were 70.00%, 93.70%, respectively; the AUC of combined test of 3 indexes for gastric cancer diagnosis was 0.91, 95% CI: 0.82-0.97, the sensitivity and specificity were 67.50% and 95.00%, respectively. Conclusion:The Hp infection rate of gastric cancer patients is higher than that of the health examiners, the serum FABP1 level of gastric cancer patients is higher than that of the healthy health examiners, the serum FABP1 level of Hp positive persons is higher than that of Hp negative persons, and Hp infection and FABP1 level may have a common carcinogenic mechanism in the occurrence and development of gastric cancer.

Objective:To evaluate the diagnostic value of neck imaging reporting and data systems (NI-RADS) based on MRI in extracavity local recurrent nasopharyngeal carcinoma (ELRNPC) and posttreatment changes (PTC).Methods:From April 2015 to September 2020, 33 cases of ELRNPC and 37 cases of PTC confirmed by pathology or follow-up were retrospectively enrolled at Zhongshan City People′s Hospital. Two radiologists independently evaluated the conventional MRI findings using NI-RADS criteria in the first step, then evaluated with conventional MRI and diffusion weighted imaging (DWI) sequences in the second step. All images were re-evaluated by one senior radiologist in the same steps after three months. Inter- and intra-reader agreements were assessed with Cohen′s Kappa test. Receiver operating characteristic curves were generated to assess the diagnostic values of NI-RADS categories between ELRNPC and PTC. The area under the curve (AUC) was compared by Delong test.Results:Inter- and intra-reader agreements of Kappa value were 0.742 and 0.909 for conventional MRI and 0.807 and 0.934 for conventional MRI with DWI. In the differential diagnosis of ELRNPC and PTC, the AUC, sensitivity, and specificity of NI-RADS categories based on conventional MRI were 0.932 (95%CI 0.846-0.978), 87.9% (95%CI 71.8%-96.6%), 94.6% (95%CI 81.8%-99.3%), and of NI-RADS based on conventional MRI with DWI were 0.991 (95%CI 0.933-1.000), 93.9% (95%CI 79.8%-99.3%), 97.3% (95%CI 85.8%-99.9%), respectively. There was a statistical difference between the AUCs of the two categories ( Z=2.20, P=0.028). Conclusions:For both the NI-RADS based on MRI with or without DWI, the differential diagnostic value of ELRNPC and PTC is excellent, while the consistency and diagnostic performance are more substantial when combined with DWI.

Objective To assess the effects of 7,8-dihydroxyflavone (7,8-DHF) on the striatum (ST) in normal cynomolgus monkeys using 99Tcm-TRODAT-1 imaging.Methods A total of six healthy female cynomolgus monkeys were included in this study.Three of them were fed with normal food (control group),and the other three were given oral administration of 7,8-DHF in addition to normal food (experimental group).The SPECT/CT imaging was performed at different time after 99Tcm-TRODAT-1 injection.The ROI of ST was drawn on images of 3 consecutive transverse slices that could be visualized best.The cerebellum (CB) was taken as the background reference area.The radioactivity uptake ratios of ST/CB at 1,3,4 and 5 h were calculated respectively.Paired-t test was used to analyze the data.Results ST radioactive uptake ratios showed continuing increase on the delay images.ST/CB uptake ratios of the control group at 1,3,4 and 5 h were 1.43±0.04,1.82±0.06,2.04±0.12,2.42±0.23,respectively,and those of the experimental group were 1.35±0.08,2.40±0.09,2.74±0.13 and 3.25±0.15 respectively.There was no significant difference between the two groups at 1 h (t =2.57,P＞0.05),while ST/CB uptake ratios of the experimental group at 3,4 and 5 h were significantly higher (t values:2.77,2.87 and 2.92,all P＜0.05).Conclusion 99Tcm-TRODAT-1 SPECT/CT imaging can be used to assess the DAT activation effect by 7,8-DHF on ST of cynomolgus monkeys.

Objective To investigate the clinical effect of Xingnaojing injection combined with gastroenteric fluid replacement in the treatment of hyperosmolar nonketotic diabetic coma ( HNDC) .Methods In accordance with different treatment methods , 150 HNDC patients who received medical care in the Neurological and Endocrinological Department of the hospital from April 2015 to April 2017 were divided into 3 groups, i.e.the conventional treatment group , the gastroenteric fluid replacement group and the Xingnaojing injection combined with gastroenteric fluid replacement group (or the combination group ), each consisting of 50 patients.Blood bio-chemical indexes and changes in plasma osmotic pressure were detected in the patients of the 3 groups, both before therapy and at hour 24 and hour 48 after therapy, and the therapeutic efficacy , rate of complications and mortality were also closely observed .Results To-tal effective rates of the gastroenteric fluid replacement group and the combination group were significantly higher than that of the con -ventional treatment group(P<0.01).As compared with that of the gastroenteric fluid replacement group , total effective rate of the combination group was also significantly higher(P<0.05).The levels of blood glucose, serum sodium, blood urea nitrogen and plasma osmotic pressure at hour 24 and hour 48 after treatment were all lower than those before treatment (P<0.01).The levels of blood glu-cose, serum sodium, blood urea nitrogen and plasma osmotic pressure in the patients of the gastroenteric fluid replacement group and the combination group were obviously lower than those of the conventional group at corresponding time points (P<0.05), and the a-bove-mentioned levels of the combination group were lower than those of the gastroenteric fluid replacement group (P<0.05).The rate of adverse reactions and mortality of the combination group were obviously lower than those of the gastroenteric fluid replacement group and the conventional group (P<0.05 or P<0.01).Conclusion The therapeutic efficacy of Xingnaojing injection combined with gas-troenteric fluid replacement in the treatment of hyperosmolar nonketotic diabetic coma is superior to those of the conventional fluid re -placement and single gastroenteric fluid replacement treatment , and this treatment method is simple and safe , which is worth further clinical extension .
