RESUMO
Objective:To investigate the safety and feasibility of the CHESS endoscpic ruler (CHESS ruler), and the consistency between the measured values and the interpretation values by endoscopic physician experience.Methods:From January 2021 to January 2022, a total of 105 liver cirrhosis patients with portal hypertension were prospectively enrolled from General Hospital, Xixia Branch Hospital, Ningnan Hospital of People′s Hospital of Ningxia Hui Autonomous Region (29 cases), and the First People′s Hospital of Yinchuan (25 cases), General Hospital of Ningxia Medical University (18 cases), Wuzhong People′s Hospital (10 cases), the Fifth People′s Hospital of Ningxia Hui Autonomous Region (10 cases), Shizuishan Second People′s Hospital (6 cases), Yinchuan Second People′s Hospital (5 cases), and Zhongwei People′s Hospital (2 cases) 8 hospitals. The clinical characteristics of all the patients, including gender, age, nationality, etiolog of liver cirrhosis, and Child-Pugh classification of liver function were recorded. A big gastroesophageal varices was defined as diameter of varices ≥5 mm. Endoscopist (associated chief physician) performed gastroscopy according to the routine gastroscopy procedures, and the diameter of the biggest esophageal varices was measured by experience and images were collected, and then objective measurement was with the CHESS ruler and images were collected. The diameter of esophageal varices of 10 randomly selected patients (random number table method) was determined by 6 endoscopists (attending physician or associated chief physician) with experience or measured by CHESS ruler. Kappa test was used to test the consistency in the diameter of esophageal varices between measured values by CHESS ruler and the interpretation values by endoscopic physician experience.Results:Among 105 liver cirrhosis patients with portal hypertension, male 65 cases and female 40 cases, aged (54.8±12.2) years old, Han nationality 82 cases, Hui nationality 21 cases and Mongolian nationality 2 cases. The etiology of liver cirrhosis included chronic hepatitis B (79 cases), alcoholic liver disease (7 cases), autoimmune hepatitis (7 cases), chronic hepatitis C (2 cases), and other etiology (10 cases). Liver function of 32 cases was Child-Pugh A, Child-Pugh B 57 cases, and Child-Pugh C 16 cases. All 105 liver cirrhosis patients with cirrhotic portal hypertension were successfully measured the diameter of gastroesophageal varices by CHESS ruler, and the success rate of application of CHESS ruler was 100.0% (105/105). The procedure time from the CHESS ruler into the body to the exit of the body after measurement was (3.50±2.55) min. No complications happened in all the patients during measurement. Among 105 liver cirrhosis patients with cirrhotic portal hypertension, 96 cases (91.4%) were recognized as big gastroesophageal varices by the endoscopists. Totally 93 cases (88.6%) were considered as big gastroesophageal varices by CHESS ruler. Eight cases were recognized as big gastroesophageal varices by the endoscopist, however not by the CHESS ruler; 5 cases were recognized as big gastroesophageal varices by the CHESS ruler, but not by the endoscopists; 4 cases were not recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler; 88 cases were recognized as big gastroesophageal varices both by the endoscopists and CHESS ruler. The missed diagnostic rate of big gastroesophageal varices by the endoscopists experience was 5.4% (5/93), and the Kappa value of consistency coefficient between the measurement by the CHESS ruler and the interpretation by endoscopists experience was 0.31 (95% confidence interval 0.03 to 0.60). The overall Kappa value of consistency coefficient by 6 endoscopists measured by CHESS ruler in big gastroesophageal varices diagnosis was 0.77 (95% confidence interval 0.61 to 0.93).Conclusion:As an objective measurement tool, CHESS ruler can make up for the deficiency of subjective judgment by endoscopists, accurately measure the diameter of gastroesophageal varices, and is highly feasible and safe.
RESUMO
Objective:To investigate the antibiotics resistance of patients with Helicobacter pylori ( H. pylori) infection of different age in Ningxia. Methods:From July to December 2021, a total of 1 040 patients with H. pylori infection confirmed by 14C-urea breath test who had no history of H. pylori treatment and underwent gastroscopy were selected from the H. pylori special outpatient clinics from Ningxia Hui Autonomous Region People′s Hospital, Ningxia Hospital of Integrated Traditional Chinese and Western Medicine, Yuanzhou District People′s Hospital of Guyuan, Wuzhong People′s Hospital, the Second People′s Hospital of Shizuishan, People′s Hospital of Zhongwei, Yinchuan First People′s Hospital. Gastric mucosa specimens were obtained under gastroscopy and cultured for H. pylori in vitro. Harvested H. pylori were detected for H. pylori drug resistance phenotype. Kirby-Bauer disk diffusion method was used to detect antibiotic sensitivity. Previous use of antibiotics of patients were recorded. The characteristics of primary drug resistance of people≤44, 45 to 59, and ≥60 years old were analyzed. Chi-square test was used for statistical analysis. Results:A total of 538 H. pylori strains were obtained from 1 040 gastric mucosa specimens cultured in vitro, with a positive rate of 51.7%. A total of 187 patients could provide information on history of antibiotics usage. The primary drug resistance rates of metronidazole, clarithromycin and levofloxacin were high, which were 95.5% (514/538), 44.6% (240/538) and 45.4% (244/538), respectively; however drug resistance of amoxicillin, furazolidone and tetracycline were not found. The double drug resistance rate was 36.4% (196/538), mainly resistant to metronidazole and clarithromycin or metronidazole and levofloxacin, the drug resistance rates were 17.8% (96/538), 18.2% (98/538), respecitively. The triple drug resistance rate was 25.5% (137/538), all of the strains were metronidazole, clarithromycin and levofloxacin resistant strains. The primary drug resistance rates to levofloxacin and clarithromycin in patients with H. pylori infection who had previous history of quinolones and macrolides were 60.9% (28/46) and 63.4% (83/131), respectively; which were higher than those of patients who had not used corresponding drugs (41.8%, 59/141 and 39.3%, 22/56), and the differences were statistically significant ( χ2=5.05 and 9.23, P=0.023, 0.002). The drug resistance rates of metronidazole of ≤44, 45 to 59, and ≥60 years old group were 94.2% (163/173), 95.5% (231/242) and 97.6% (120/123), respectively, and the differences were not significant ( P>0.05). The single drug resistance rates of levofloxacin of ≤44, 45 to 59, and ≥60 years old group were 34.7% (60/173), 48.3% (117/242) and 54.5% (67/123), respectively, and the differences were statistically significant ( χ2=12.95, P=0.002). The levofloxacin resistance rate of ≤44 years old group was lower than that of 45 to 59, and ≥60 years old group, and the differences were statistically significant ( χ2=7.70 and 11.49, P=0.006, 0.001). The single drug resistance rates of clarithromycin of ≤44, 45 to 59, and ≥60 years old group were 36.4% (63/173), 50.4% (122/242) and 44.7% (55/123), respectively, and the differences were statistically significant ( χ2=8.00, P=0.018). The clarithromycin resistance rate of ≤44 years old group was lower than 45 to 59 years old group, and the difference was statistically significant ( χ2=8.00, P=0.005). Dual drug resistance rates of levofloxacin and clarithromycin of ≤44, 45 to 59 and ≥60 years old group were 49.7%(86/173), 70.2%(170/242), 45.5%(56/123), and the difference was statistically significant( χ2=27.63, P<0.001). The resistance rate of clarithromycin and levofloxacin in 45 to 59 years old group was higher than that in ≤44 and ≥60 years old group, and the difference was statistically significant ( χ2=18.00 and 21.13, both P<0.001). Conclusions:Primary drug resistance rates to metronidazole, levofloxacin and clarithromycin are high in patients with H. pylori infection of different ages in Ningxia. Individualized eradication therapy guided by drug resistance test is recommended.

There were 538 males and 282 females, aged (56±13)years. Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.
RESUMO
Objective:To investigate the curative effect of different restorations for deciduous teeth defect of children.Methods:67 children with teeth defecting seriously and being unable to fill restore were enrolled from January 2011 to January 2015 and randomly divided into three groups,one group of patients accepted metal crown restoration (Group A,n=22),one group adopted ceramic inlay restoration (Group B,n=22),and the last one accepted silver amalgam filling (Group C,n=23),the curative effect and incidence of adverse reactions among three groups in the period follow-up were compared.Results:In the period of 18-month follow-up,6 patients of toothache,5 patients of food impaction and crevices between restorations and teeth,3 cases of gingival congestion,2 cases of secondary caries were observed in group C;3 cases of toothache,1 case of food impaction,gingival congestion,crevices between restorations and teeth and secondary caries were observed in group B;2 cases of toothache and food impaction,1 case of gingival congestion were observed in group A.The incidence of adverse reactions in group A and group B was lower than those in group C (P＜0.05),which was lower in group A than that in group B,but no significant difference was found between group A and group B (P＞0.05).Conclusion:The restoration of metal crown and ceramic inlay deserved popularization had better curative effect and safety for deciduous teeth defect of children than silver amalgam filling.
