The presence of the cervical artery sulcus ring was found on the atlas in 56 out of 346 air pilots. The X ray appearance could be classified as follows. Type Ⅰ:Complete sulcus ring in 32 cases, in whom the sulcus might be complete unilaterally or bilatrally. Type Ⅱ: Incomplete or half ring in 18 cases. This type could be further divided into Ⅱ a , consisting of 4 persons with half ring in the anterior aspect, andⅡ b , half ring posteriorly in14 persons. Type Ⅲ: Broken ring in 6 persons. It is an anatomic variation, which may be have some relationship to vertigo. It is suggested that the presence of cervical artery sulcus ring on atlas should be taken as an disqualification factor in air pilot recruitment.

BACKGROUND:Bone marrow mesenchymal stem cel transplantation has not been thoroughly reported on its effects on apoptosis in hepatoma carcinoma cel s and inflammatory factor level.
OBJECTIVE:To investigate the effect of rat bone marrow mesenchymal stem cel s on dynamic change of inflammatory factors and cel apoptosis during hepatocarcinogenesis.
METHODS:Sixty healthy Sprague-Dawley rats were divided randomly into healthy group (n=30), control group (n=30) and transplantation group (n=30). Healthy group was given ordinary feed and normal water, while other groups were given diethylnitrosamine solution in drinking water to induce liver cancer models. Then, rats in the transplantation group were subjected to bone marrow mesenchymal stem cel transplantation via the tail vein. Two weeks after cel transplantation, CXCL5, interleukin-8 and interleukin-6 levels were tested by ELISA, mRNA level of hepatocyte nuclear factor 1αdetected by RT-PCR, expression of Bcl-2 and Bax in liver tissue measured by immunohistochemical method, and liver cancer cel apoptosis index detected by TUNEL technique.
RESULTS AND CONCLUSION:After modeling, the expressions of CXCL5, interleukin-8 and interleukin-6 in the control group were significantly higher than those in the healthy group (P<0.05), while these indexes were reduced significantly after bone marrow mesenchymal stem cel transplantation (P<0.05) and close to the normal levels (P>0.05). Bone marrow mesenchymal stem cel transplantation significantly up-regulated the mRNA level of hepatocyte nuclear factor 1αin the liver tissue that was decreased obviously after modeling (P<0.05). In addition, the expression of Bcl-2 was reduced, while the expression of Bax and the apoptosis index increased significantly in the transplantation group compared with the control group (P<0.05). These findings indicate that bone marrow mesenchymal stem cel transplantation contributes to hepatocyte differentiation and regeneration in liver cancer rats by reducing serum inflammatory factor levels and promoting apoptosis in hepatoma carcinoma cel s.

Objective To describe the level of self-perceived burden (SPB) and analyze its influencing factors among the patients with advanced lung cancer, in order to provide a theoretical basis for individualized nursing care. Methods A total of 102 hospitalized patients with lung cancer from 3 hospitals in Shandong province were investigated by the Self-Perceived Burden Scale for Cancer Patient (SPBS-CP). Results The total score of the SPBS-CP was (60.31±17.06) points, which indicated at a moderate level. Those patients rated the highest score on the sub-scale of economic/family burden (22.04±6.72) points, the lowest score on the sub scale of care burden (10.28±3.62) points. Single factor analysis and regression results showed that different work conditions, different stages were related with SPB. Conclusions Patients with moderate and advanced lung cancer had a moderate or higher level of SPB. Staff nurses should focus on the psychological status of the patients and take positive interventions to release the negative emotional experiences.

Objective To explore the clinical and imaging factors influencing the patients' prognosis after preoperative radiotherapy for local advanced rectal cancer.Methods We retrospectively analyzed 106 locally advanced rectal cancer patients from June 2004 to September 2015 in our institution.All patients underwent preoperative radiotherapy.According to the Mandard score,patients were divided into 5 groups (TRG1-5).All patients were divided into two groups according to the TRG,which including good responder (TRG1 + 2) and poor responder (TRG3 + 4 + 5) groups.All of the tumor ADC values of post-RT were measured by Diffusion-weighted MRI technology,and the relationship between tumor ADC values of post-RT and TRG was analyzed.Results In univariate analysis,age,chemotherapy,pT,pN,differentiation degree,vascular invasion and TRG were significantly associated with overall survival (x2 =3.945-8.110,P ＜ 0.05).Multivariate analysis indicated that differentiation degree and TRG were the independent prognostic factors for OS (x2 =5.221,6.563,P ＜ 0.05).No significant difference was found between long-course and short-course radiotherapy group (P ＞ 0.05) in OS.The good responder group had a favorable survival in 5-year OS compared to the poor responder group (x2 =8.110,P ＜ 0.05).Preoperative radiotherapy,preoperative chemotherapy,pathological type,differentiation degree and gross type,vascular tumor thrombus and tumor ADC values of post-RT were significantly associated with TRG (x2 =4.189-18.139,P ＜ 0.05).The best critical point of tumor ADC values of post-RT was 1.7 x 10-3 mm2/s by using ROC curve.The accuracy of tumor ADC values of post-RT in predicting TRG1 + 2 was 70％.Conclusions The TRG can predict the efficacy of preoperative radiotherapy in patients with locally advanced rectal cancer based on the Mandard score.There was no significant difference in OS between long-course radiotherapy group and short-course radiotherapy group.The tumor ADC values of post-RT might become a potential factor to predict TRG in patients with locally advanced rectal cancer after preoperative radiotherapy.

Objective To observe the clinical effect of Shumu-Yuntu-Zhike decoction with conventional treatment for the Gastroesophageal Reflux Cough (GERC).Methods A total of 64 patients with GERC were randomly divided into the conventional treatment group and the combined treatment group, 32 in each. The conventional treatment group took the Rabeprazole capsule and Mosapride Citrate Tablets, and the combined treatment group received the traditional prescription of Shumu-Yuntu-Zhike decoction on the basis of the conventional therapy. Two groups were treated for 8 weeks and evaluated the effect with the Visual analogue scale (VAS), Reflux diagnostic questionnaire (RDQ) and Chronic cough impact questionnaire (CCIQ) before and after 4 and 8 weeks' treatment.Results After 4 week treatment, the VAS (4.47 ± 1.32vs. 6.22 ± 1.34;t=-5.859,P<0.01), CCIQ (32.60 ± 5.83vs. 47.32 ± 5.56,t=-11.548,P<0.01) in the combined treatment group decreased significantly than the conventional group, but the RDQ (13.62 ± 2.89vs. 13.67 ± 2.77;t=-0.079, P=0.937) showed no significant difference between the two groups. After 8 weeks' treatment. After 8 week treatment, the VAS (2.57 ± 1.69vs. 4.55 ± 2.06;t=-4.676,P<0.01), CCIQ (12.47 ± 3.41vs. 23.47 ± 3.55;t=-14.126,P<0.01) in the combined treatment group decreased significantly, but the RDQ (9.18 ± 2.77vs. 9.3 ± 2.43,t=-0.202,P=0.841) showed no significant difference between the two groups. After the treatment, the total effective rate of combined treatment group was 90.6% (29/32), while the control group was 68.7% (22/32). There was significant difference between the two groups (χ2=4.730,P=0.030).Conclusions The therapy of Shumu-Yuntu-Zhike decoction combined with conventional therapy can relieve the symptom of gastroesophageal reflux cough.

OBJECTIVE: To analyze genetic variant in a pedigree affected with congenital high myopia. METHODS: Whole exome sequencing (WES) was carried out for the proband. Suspected variation was verified with Sanger sequencing. The pedigree was also subjected to co-segregation analysis. RESULTS: WES has identified a novel splice site heterozygous variant (c.2556+1G>A) in the COL11A1 gene in the proband. Co-segregation analysis of the pedigree showed that the affected mother and two daughters of the proband have carried the same variant(c.2556+1G>A), while his unaffected father and sister did not. Based on the ACMG Standards and Guidelines for the Interpretation of Sequence Variants, the variant was classified as "likely pathogenic" (PVS1+PM2). CONCLUSION A novel splice variant (c.2556+1G>A) of the COL11A1 gene has been identified in a pedigree affected with congenital high myopia, which probably underlies the disease.

Objective To investigate the value of strong ion gap (SIG) in predicting the severity of acute pancreatitis (AP) based on the revised Atlanta classification. Methods A total of 133 patients with AP admitted from January, 2015 to December, 2016 were enrolled. Of them, there were 55 with mild AP (MAP), 52 with moderately severe AP (MSAP) and 26 with severe AP (SAP). All patients with AP conformed to the diagnostic criteria of Guidelines or Diagnosis and Treatment of Acute Pancreatitis set in 2014 in China. Patients with other underlying diseases that might influence the clinical outcome were excluded, including those with diabetic ketoacidosis, chronic renal failure and other disorders. The changes in blood SIG levels in each group were observed. The correlations between SIG and acute physiology, chronic health evaluation (APACHE) Ⅱ score, Ranson score and length of hospital stay were analyzed. The receiver operating characteristic curves (ROC) were plotted to determine the efficiency of SIG, Scr, APACHE Ⅱ score, and Ranson score for predicting the severity of acute pancreatitis. Results The level of SIG in the SAP group was the highest, followed by the MSAP group and the lowest in the MAP group.There were significant differences in pairwise comparisons (P<0.01). The correlations between SIG and APACHE Ⅱ score (r=0.567, P<0.01), Ranson score (r=0.502, P<0.01), and length of hospital stay were positive (r=0.589, P<0.01). There was no statistical difference in the area under curve (AUC) between SIG and APACHE Ⅱ score (0.874±0.029 vs.0.895±0.025, P>0.05) and as well as Ranson score (0.874±0.029 vs. 0.890±0.027, P>0.05) for predicting moderately-severe acute pancreatitis, but SIG was superior to Scr (0.874±0.029 vs. 0.735±0.043, P<0.01). There was a significant difference in AUC between SIG and Scr (0.910±0.030 vs. 0.755±0.054, P<0.01), but no statistical differences between SIG and APACHE Ⅱ score (0.910±0.030 vs. 0.867±0.034, P>0.05) and Ranson score (0.910±0.030 vs. 0.871±0.032, P>0.05) for predicting severe acute pancreatitis. Conclusion SIG has important clinical significance for predicting the severity of acute pancreatitis.
