Objective:To analyze the survival time, prognostic factors and the value of postoperative thoracic radiotherapy in resected small cell lung cancer (SCLC) patients.Methods:Clinic opathological data of SCLC patients who received surgical treatment in Cancer Hospital & General Hospital of Ningxia Medical University from April 2014 to September 2021 were enrolled in this retrospective study. All patients were subject to follow-up. The survival time of SCLC patients was evaluated by Kaplan-Meier method. Univariate and multivariate analyses of prognostic factors were performed by Cox proportional hazard model.Results:A total of 64 patients with SCLC were enrolled in the study. The 5-year overall survival (OS) rate was 43.5%. Univariate analysis showed that TNM staging ( P=0.027), postoperative neutrophil-lymphocyte ratio (NLR) ( P=0.039) and adjuvant thoracic radiotherapy ( P=0.041) were the prognostic factors. Multivariate analysis showed that TNM staging ( P=0.038) and adjuvant thoracic radiotherapy ( P=0.022) were the prognostic factors in patients with SCLC. The 5-year OS rates of patients with and without adjuvant thoracic radiotherapy were 71.6% and 35.4% ( P=0.028), respectively. There was a statistically significant difference in the 5-year OS rates between pathological stage N 2 SCLC patients with or without adjuvant thoracic radiotherapy (75.0% vs. 0%, P=0.030). Conclusions:TNM staging and postoperative adjuvant thoracic radiotherapy are prognostic factors in patients with SCLC undergoing surgical treatment. Pathological stage N 2 SCLC patients can benefit from adjuvant thoracic radiotherapy.

Objective@#The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated.@*Methods@#Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check.@*Results@#(1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01).@*Conclusions@#There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.

Objective To evaluate the value of MRI diffusion tensor imaging (DTI) on diagnosis of traumatic brain injury(TBI). Methods Twenty two patients with TBI 1 to 7 days post-injury and 14 healthy controls were studied with DTI and conventional MRI. The fractional anisotropy (FA) was quantified from different regions of interest (ROI) including the genu of corpus callosum (CC), the splenium of CC, the genu of internal capsule (IC) and the posterior limb of IC bilaterally. The FA value of the same ROI was compared between TBI group and control group, and FA value of the lesion side was compared with the mirror healthy side in TBI group. Correlations between the FA and Glasgow coma scale (GCS) in TBI patients were analyzed with Pearson linear correlation. Results Compared with control group, the FA value decreased significantly in each ROI (P<0.01). Compared with the healthy side, FA value was also significantly lower in lesion side in TBI group (P<0.01). The FA value in all the sites were not correlated with GCS in TBI group (P>0.01).Conclusion DTI is sensitive for detecting the acute traumatic injury of white matter and evaluate the degree of injury. It offers the possibility to diagnose TBI earlier and accurately.

Objective To evaluate changes of regional cerebral metabolism by proton MR spectroscopy (~1H-MRS) in patients with minimal hepatic encephalopathy (MHE) and to correlate these changes with the neuropsychological test. Methods Fifty-four patients with cirrhosis including nine patients with hepatic encephalopathy (HE),23 patients with MHE,22 patients without HE and 13 controls underwent neuropsychological tests and ~1H-MRS scanning. The volumes of interest included occipital gray matter and left parietal white matter regions. Ratio of spectral peak areas of N-acetylaspartate (NAA),choline (Cho),myo-inositol (mI),and glutamine/glutamate (Glx) relative to creatine (Cr) were acquired. Statistical analysis was conducted using independent t test and one-way analysis of variance. The results of different groups were compared by using the nonparametric Mann-Whitney U test with Bonferroni correction. Correlations among the ~1H-MRS ratios, the grade of HE, neuropsychological test and ammonia data were calculated with Spearman correlation test. Results The ratios of NAA/Cr,Cho/Cr,mI/Cr,Glx/Cr of the occipital gray matter and left parietal white matter regions in patients with cirrhosis are 1.55±0.12,0.48±0.10,0.42±0.14,2.52±0.48 and 1.73±0.17,0.75±0.16,0.42±0.16,2.75±0.59respectively,and they are 1.53±0.10,0.48±0.09,0.51±0.11,2.20±0.39 and 1.69±0.15,0.82±0.14,0.53±0.12,2.40±0.40 in patients without HE,1.58±0.13,0.48±0.08,0.38±0.13,2.62±0.39 and 1.78±0.18,0.74±0.14,0.38±0.15,2.84±0.58 in patients with MHE,1.54±0.12,0.50±0.13,0.29±0.07,3.04±0.31 and 1.70±0.19,0.62±0.16,0.29±0.07,3.37±0.38 inpatients with HE.Compared with controls, decreased mI/Cr and Cho/Cr ratios and elevated Glx/Cr ratios were found in patients with cirrhosis (t=3.196,9.394,-6.527,P<0.01,occipital gray matter. t=5.592,9.717,-6.681,P<0.01,left parietal white matter= and in subgroup of patients without HE, with MHE and HE (F=5.097,25.896,20.204,P<0.01,occipital gray matter.F=16.435,28.660,21.283,P<0.01,left parietal white matter).Significant difference in these metabolic alterations was also found among the different groups of cirrhosis especially the ratios of Glx/Cr in occipital gray matter and left parietal white matter (P<0.0084).The ratios of mI/Cr also significantly altered between patients without HE and with MHE (P<0.0084).There was a significant negative correlation between the ratios of Cho/Cr,mI/Cr and the grade of HE (P<0.01= and a significant positive correlation between the ratios of Glx/Cr and the grade of HE (r=0.709,P<0.01,occipital gray matter; r=0.720,P<0.01,left parietal white matter=.NCT-A and DST of controls is (49±8) s and 39±6.They are (134±37),(83±26),(64±22) second and 15±2,25±9,35±8 in patients with HE,MHE and without HE respectively.The metabolic alterations of Cho/Cr,mI/Cr,Glx/Cr correlated significantly with neurepsychological tests in all subjects (P<0.01=.There was a significant positive and a negative correlation between the ratios of Glx/Cr and the data of NCT-A and DST respectively (r=0.570,-0.642,occipital gray matter; r=0.541,-0.632,left parietal white matter).The metabolic alterations of Glx/Cr had no correlation with ammonia data as well as other metabolic alterations.Conclusions ~1H-MRS study shows cerebral metabolic alterations of gray and white matter in patients with cirrhosis,especially the reduction in mI/Cr ratio and increase in Glx/Cr ratio. These changes correlate well with the neuropsychological tests and may be useful in predicting the presence of MHE.
