The AUC, accuracy, sensitivity, and specificity of serum miR-106b-5p, miR-760 combined with low-dose spiral CT in diagnosing early lung cancer were 0.96, 90.00%, 94.44%, and 85.56%, respectively. The accuracy of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 and low-dose spiral CT ( χ2=11.52, P=0.001; χ2=10.72, P=0.001; χ2=5.14, P=0.023), the sensitivity of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 and low-dose spiral CT ( χ2=4.77, P=0.029; χ2=7.46, P=0.006; χ2=11.51, P=0.001), the specificity of the three combined diagnosis was higher than that of individual diagnosis of miR-106b-5p, miR-760 ( χ2=7.11, P=0.008; χ2=4.12, P=0.042) . Conclusion:The serum level of miR-106b-5p is significantly increased in early lung cancer patients, while the serum level of miR-760 is significantly reduced. The combination of miR-106b-5p, miR-760 and low-dose spiral CT has high diagnostic value for early lung cancer.

Objective:To explore the value of coronary computed tomography angiography(CCTA)in assessing the relationship between the fat volume around coronary plaque and the abnormal coronary hemodynamics.Methods:A total of 218 hospitalized patients admitted to Cangzhou People's Hospital from June 2022 to September 2023 were selected.In these patients,108 patients without coronary heart disease(CHD)were included in the control group,and 110 CHD patients were included in the observation group.All patients underwent CCTA examination to compare the CT imaging values(FFRCT)of the fat volume around heart and blood flow reserve fraction between the two groups.Receiver operating characteristic(ROC)curve was performed to analyze the efficacy of the fat volume around heart and FFRCT values in predicting coronary artery plaques.Additionally,Pearson's method was used to analyze the correlation between fat volume around heart and FFRCT.Results:The fat volume around heart in the observation group was(168.70±38.16)cm3,which was significantly higher than(98.75±21.19)cm3 in the control group,and the FFRCT value(0.78±0.11)of the observation group was lower than(0.89±0.10)in the control group,with statistically significant differences(t=16.688,8.041,P<0.05),respectively.In the observation group,89 patients occurred plaque,and 21 patients did not occur plaque.In the observation group,the fat volume around heart in patients with plaques was(176.63±34.15)cm3,which was significantly higher than(133.52±36.85)cm3 in patients without plaques,and the FFRCT value in patients with plaques was(0.76±0.10),which was significantly lower than(0.85±0.11)in patients without plaques,with statistically significant differences(t=4.945,3.815,P<0.05),respectively.According to Pearson's analysis,there was a negative correlation between the fat volume around heart and FFRCT value.According to Spearman's analysis,with or without plaques appeared positive correlation with the fat volume around heart in CHD patients,and they appeared negative correlation with FFRct value.According to ROC curve analysis,the area under curve(AUC)values of fat volume around heart,FFRCT,and the combination of them were respectively 0.777,0.726 and 0.930 in predicting the plaques of CHD patients.Conclusion:Hemodynamics and fat volume around heart that is measured by CCTA can predict coronary plaque,and there is a certain of relationship between coronary hemodynamics and the fat volume around coronary artery plaques,which appears negative correlation.

Objective To investigate HPV vaccine hesitancy and influencing factors among parents of primary and secondary schools in Guangyuan, and to provide scientific countermeasures for reducing the hesitancy rate of HPV vaccine in parents. Methods Using stratified multi-stage cluster random sampling, 1,018 parents of girls in primary and secondary schools in Guangyuan were selected for a questionnaire survey from March to July 2021. The data were analyzed by Chi-square test and multivariate logistic regression model. Results The hesitancy rate of HPV vaccine in parents was 42.95%. Multivariate logistic regression analysis showed that families with low economic income, parents who believed that HPV vaccination would have long-term side effects, and be unsafe and expensive, and parents who concerned with the effect of HPV vaccine on the prevention of cervical cancer and insufficient supply of first doses of vaccine, had positive effects on HPV vaccine hesitancy (OR = 2.02, 1.44, 3.13, 1.53, 3.76, and 2.43, respectively, P < 0.05). Conclusion HPV vaccine hesitancy rate is high among parents of primary and secondary schools in Guangyuan. It is necessary to fully promote school education and increase the publicity of HPV vaccine to improve parents' awareness of HPV vaccine. Government departments need to make an overall plan to reduce vaccine costs and ensure sufficient vaccine quantity, so as to reduce parents' hesitation to vaccinate their children with HPV vaccine.

OBJECTIVE: To investigate the relationship of group B (GBS) colonization in late pregnancy with perinatal outcome. METHODS: Pregnant women who underwent antenatal check-up at General Hospital of PLA Eastern Theater Command and the First Affiliated Hospital of Nanjing Medical University from January 2016 to December 2018 were enrolled in the study. The vaginal and rectal swab samples were collected for GBS culture at 35-37 weeks of pregnancy. The perinatal outcomes of positive and negative GBS groups were compared. The GBS-positive group samples were tested for antibiotic susceptibility. In GBS positive group the maternal and child perinatal outcomes were compared between pregnant women with antibiotics treatment and those without antibiotics. RESULTS: A total of 13 000 pregnant women were enrolled, and the overall colonization rate of GBS was 3.65%(475/13 000). The colonization rate of GBS in the vagina was 2.33%(303/13 000), and the colonization rate in the rectum was 1.75%(227/13 000). Through the collection and detection of rectal specimens, the positive rate of GBS increased by 56.77%(172/303). The monthly colonization rate of GBS showed significant fluctuations with the highest in March and October (all < 0.05). The sensitivity of 475 GBS-positive specimens to ceftriaxone, vancomycin and linezolid were 100%, and the sensitivity to ampicillin and penicillin were 97.26%and 93.47%, respectively. The resistance rates of the strains to levofloxacin, clindamycin, erythromycin and tetracycline were 30.11%, 48.00%, 52.21%and 88.63%. The incidence of premature rupture of membranes, postpartum hemorrhage, puerperal infection, neonatal pneumonia and sepsis in GBS positive group were significantly higher than those in GBS negative group (all < 0.01). In pregnant women with positive GBS, the incidence of puerperal infection, neonatal infection and admission to the NICU in the antibiotic group were significantly lower than those in the non-antibiotic group ( < 0.05 or < 0.01). CONCLUSIONS The total colonization rate of GBS is low. The detection of GBS can be significantly improved by supplementing rectal examination. Ceftriaxone, ampicillin and penicillin are currently the drugs of choice for the prevention and treatment of GBS-related diseases. GBS infection can increase the incidence of maternal and child complications. The use of antibiotics during labor can improve the outcome of mothers and infants.

Objective To evaluate the efficacy,safety of rigid gas permeable contact lens (RGPCL) wearing for over 5 years in different degrees of keratoconus eyes.Methods A retrospective case study was performed.The clinical data of 217 eyes with different degree of keratoconus from 126 keratoconus patients who fitted with RGPCL in Beijing Tongren Hospital from 2000-2010 over 5 years were analyzed.The eyes were divided into mild keratoconus group (Ks≤45.0 D),moderate keratoconus group (45.0 D＜ Ks ＜ 52.0 D) and severe keratoconus group (Ks ≥52.0 D) according to the severity.Uncorrected visual acuity (UCVA,LogMAR),spectacle corrected visual acuity (SCVA) and RGP corrected visual acuity (RGPVA) was examined before RGPCL wearing and the end of followingup after RGPCL wearing.The refraction,corneal curvature,corneal astigmatism were measured with auto-refractomer/keratometer and keratoconus screening analysis system of computer-assisted corneal topography.Comparisons of the changes of corrected visual acuity and corneal parameters were assessed.Results The RGPVA was 0.09±0.17,0.05±0.07 and 0.07 ±0.07 in the mild,moderate and severe keratoconus group,respectively,showing a significant difference among the three groups (F=0.522,P=0.594);The △Ks was (2.25±5.42),(0.26±3.44) and (-4.52±3.44)D,and △Kf was (2.06±4.98),(1.02±3.41) and (-2.03±5.05)D,and the change value of corneal astigmatism was (0.19±2.87),(-0.78±2.84) and (-2.44±3.77)D in the mild,moderate and severe keratoconus group(all at P＜ 0.05),respectively,with the minimum amount of change in the severe keratoconus group.The variation of differential sector index (△DSI) was-0.33 ± 1.64,0.14±3.01 and-2.11 ±4.28;the variation of center/ surround index (△CSI) was-0.41 ± 1.07,0.03±2.22 and-2.49±4.15;the variation of standard deviation of power (△SDP) was-0.43 ±0.64,-0.02 ±0.89 and-1.67 ± 1.68;the variation of keratoconus prediction index (△KPI)was 0.00±0.07,0.03±0.09 and-0.05±0.11 in the mild,moderate and severe keratoconus group,respectively,and the reduced amount in above parameters was much more in the severe keratoconus group than that in the mild and moderate keratoconus group (all at P＜0.01).Mild conjunctivitis and corneal affection occurred in 12 eyes (5.5％)during the follow-up.Conclusions Long-term wearing RGPCL can improve the visual acuity and slow the tendency of corneal curvature increase in keratoconus eyes,and this procedure is safe and effective for the correction of different degree of keratoconus.

Human gut microbiota contains around 1014 colonized intestinal microbes.Gut microbiome outnumbers the human gene pool by ten to one.Therefore,it's generally considered to be our "second gene pool".Several research have clarified that the cycle of "maternal intestinal microbes-placental microbes-fetal intestinal microbes" plays a critical role in the neurological and immune regulation and metabolism in infants,which may contribute to the furtherance of research on gut microbes.We summarized the factors affecting the colonization of maternal and fetal gut microorganisms during perinatal period from recent research.

Objective To investigate the safety and feasibility of laparoscopic wedge resection for gastric gastrointestinal stromal tumors ( GIST ) . Methods One hundred GIST patients treated in our department between 2010 and 2014 were retrospectively enrolled, and their clinicopathological data were reviewed. Fifty patients underwent laparoscopic wedge resection, and open surgery cases were 1 ∶ 1 matched by tumor diameter. The clinicopathological characteristics, perioperative related factors, postoperative nutritional status and short?term outcome were compared between the two groups. Results Among the clinicopathological characteristics, only the age was of statistical significance (61.58±10.43 vs. 56.40±9.82, P=0.012) . Over fifty percent of the tumors occurred in the gastric body. Although the short?term survival did not show statistical significance, the laparoscopic group showed predominant advantages in estimated blood loss [(48.60±48.89) ml vs. (137.60±140.69) ml, P<0.001], average hospital stay[ (12.14±4.32) d vs.(17.22±7.11) d, P<0.001], oral intake time[ (3.76±1.73)d vs. (6.28±3.73)d, P<0.01], decline of prealbumin [(0.07±0.04)g/L vs. (0.11±0.05)g/L, P<0.001)], decline of transferrin [(0.51±0.29)g/L vs. (0.64±0.30) g/L, P=0.034] and complication (2.0% vs. 14.0%, P=0.027). Conclusion Laparoscopic wedge resection is feasible and safe for GIST surgery, allows a rapid recovery and having a better nutritional status in patients, and is a less invasive approach for patients.

Objective To investigate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with covered stent in the treatment of portal hypertension in patients with hepatocellular carcinoma.Methods The clinical data of 46 patients with primary hepatocellular carcinoma and portal hypertension who received TIPS with stent treatment were retrospectively analyzed.After treatment,liver function,shunt patency,re-bleeding rate,hepatic encephalopathy,ascites,gastric intestinal symptoms, lifetime and causes of death were analyzed. Compare t test was performed for measurement data comparison among groups.The survival curves were used to analyse the cumulative stent shunt patency rate,the incidence of hepatic encephalopathy and the survival rate.Results After the operation,portal vein pressure significantly decreased compared with that before operation [(16.2 ± 4.6 )mmHg vs (28.3±5 .1)mmHg,1 mmHg=0.133 kPa],and the difference was statistically significant (t =21 .30, P <0.05).There was no significant difference in liver function before and after operation [(6.8 ±1 .8) score vs (6.9±1 .5)score,P >0.05].Cumulative stent shunt patency at 3,6,12,24,36 month after operation was 100.0%,95 .6%,93.5 %,91 .3% and 91 .3%,respectively.The cumulative incidence of hepatic encephalopathy was 6.5 %,8.7%,13.0%,17.4% and 26.1 %,respectively;cumulative survival rate was 95 .7%,82.6%,67.4%,43.5 % and 32.6%,respectively.In 10 cases of refractory ascites, ascites of all the patients reduced with different degree after operation and gastrointestinal uncomfortable symptoms were relieved.Conclusion In patients with primary hepatocellular carcinoma and portal hypertension,who have gastrointestinal bleeding or refractory ascites,treatment of TIPS with covered stents could effectively lower portal pressure,prevent re-bleeding and reduce the volume of ascites.

PurposeTraumatic pancreatitis which has a high mortality rate is likely to be misdiagnosed. This study aims to analyze the clinical manifestations and CT findings of traumatic pancreatitis, so as to improve its early diagnosis and treatment.Materials and Methods The clinical manifestations and CT images of 25 patients with traumatic pancreatitis confirmed by operation or post-treatment review were analyzed retrospectively. Pancreatic injuries were classified as superficial lesions (with the depth of trauma less than 50% of the thickness of pancreas) and deep lesions (with the depth of trauma more than 50% of the thickness of pancreas). The clinical manifestations, CT findings and the complicated organ injuries in these two types of pancreatic trauma were analyzed.Results Eight patients had superficial lesions, and 17 patients were with deep lesions. Nine patients had complicated organ injuries. Patients with deep lesions showed a more severe abdominal pain, nausea, vomiting, rebound tenderness and muscular tension than those patients with superficial lesions. The serum amylases increased in all the patients. Pancreatic-relevant complications including pancreas pseudocyst, pancreatic fluid leakage and peritonitis occurred in 7 patients who accepted a delayed operation. Three out of 8 patients with superficial pancreatic injuries were missed on plain CT scan in the first time. Among 17 patients with deep pancreatic trauma, 12 had incomplete laceration, 5 had complete laceration, and 1 was missed in the first time. The direct CT features of pancreatic trauma were focal abnormal attenuation and/or discontinuity in pancreatic parenchyma.Conclusion The clinical manifestations of patients with traumatic pancreatitis are complicated. The direct CT features of pancreatic trauma include heterogeneous density of pancreatic parenchyma and/or interruption. Trauma's depth is closely related to the main injury of pancreatic duct. It is worth to be aware of the indirect signs such as peripancreatic oozy and other viscera damages.
