Objective To evaluate the efficacy of Disposcope endoscope for tracheal intubation in patients with difficult glottis exposure.Methods Sixty adult patients of both sexes,aged 22-68 yr,scheduled for elective oro-tracheal intubation under general anesthesia,whose glottis was not visible under Macintosh laryngoscope (grade Ⅲ or according to Cormach-Lehane Grading of laryngoscopic view),were randomized into 2 groups (n =30 each) using a random number table:group Macintosh laryngoscope-assisted Disposcope endoscope (group DM) and group Disposcope endoscope (group D).The glottis exposure condition and time,intubation condition and time,assisted lifting mandible,laryngeal mucosa bleeding and postoperative sore throat and hoarseness were recorded.Results The success rate of intubation at second attempt achieved 100％ in the two groups.Compared with group DM,the incidence of assisted lifting mandible was decreased,and no significant changes were found in the success rate of glottis exposure,glottis exposure time,intubation time,success rate of intubation at first attempt,incidence of laryngeal mucosa bleeding,and postoperative sore throat and hoarseness in group D.Conclusion Disposcope endoscope can improve the condition for tracheal intubation significantly after lifting mandible in patients with difficult glottis exposure.

Objective:To investigate whether radiotherapy should be delivered before the application of immune checkpoint inhibitor PD-1 in patients with advanced non-small cell lung cancer (NSCLC) and evaluate the effect of previous radiotherapy on the efficacy and pulmonary toxicity of PD-1 inhibitor.Methods:Clinical data of patients with stage Ⅳ NSCLC who received immunotherapy in Henan Cancer Hospital from March 2015 to September 2019 were retrospectively analyzed. The baseline data of patients, the status of radiotherapy and immunotherapy and the pulmonary toxicity were collected. According to whether radiotherapy was given before PD-1 inhibitor application, all patients were divided into the previous radiotherapy and non-radiotherapy groups. Survival analysis was performed by Kaplan- Meier method. Results:A total of 90 patients were enrolled including 39 cases in the previous radiotherapy group and 51 cases in the non-radiotherapy group. The median follow-up time was 22.9 months. The median progression-free survival (mPFS) in the previous radiotherapy group was 7.5 months (95% CI 5.4-9.5 months), significantly longer compared with 4.1 months (95% CI 3.1-5.1 months) in the non-radiotherapy group ( P=0.003). The median overall survival (mOS) significantly differed between two groups[15.2 months (95% CI 12.3-18.1 months) vs. 9.3 months (95% CI 6.1-12.5 months)]( P=0.040). The incidence of pulmonary toxicity showed no significant difference between two groups ( P=0.154). Conclusions:Patients with stage Ⅳ NSCLC patients in the previous radiotherapy group obtain significantly better mPFS and mOS and similar pulmonary toxicity compared with their counterparts in the non-radiotherapy group. Nevertheless, the findings remain to be validated by subsequent investigations with larger sample size.

Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.

Objective To survey the prevalence of greenhouse farmer's lung and related risk factors in part of rural areas of Liaoning Province.Methods Using uniform scheme,procedures and questionnaire,a survey for 5420 farmers(2660 men and 2760 women)with complete data who work inside greenhouses was performed in Shenyang,Xinmin,Chaoyang,and Jinzhou between August 2006 and June 2009.Pulmonary function tests was performed for every active farmer.Results Greenhouse farmer's lung was diagnosed in 308 cases,205 men(66.55%,205/308)and 103 women(33.44%,103/308),a prevalence of 5.7%(308/5420).The prevalence rate of greenhouse farmer's lung in males was significantly higher than that in females(?2=39.93,P0.05).In the 308 cases,the number of patiernts presented with fever chill,cough/sputum,chest tightness/shortness of breath were 180(58.44%),192(62.34%),160(51.95%)respectively,and the number of crepitations,radiological changes,spirometry abnormalities and serum IgE antibodies(+)was 164(53.25%),153(49.68%),147(47.73%)and 136(44.16%)at the time of the study.62.34%(192/308)of patients with greenhouse farmer's lung were mild and 38.66%(116/308)were severe.Conclusion The total prevalence rate of greenhouse farmer's lung in part of rural areas of Liaoning Province was 5.7% and multiple risk factors were associated with the disease.

OBJECTIVE: To systematically evaluate the clinical effect of cultured milk products as adjunctive therapy in the anti- Helicobacter pylori (H. pylori) treatment.
 METHODS: The randomized controlled trials (RCT) and Quasi-randomized controlled clinical trials (Quasi-RCT), which were used to evaluate the efficacy and safety of eradicating H. pylori by fermented milk-based routine treatment, were searched and collected in Pubmed, Embase, CNKI (China National Knowledge Infrastructure), CBM (Chinese BioMedical Literature Database), Wangfang Database, VIP (VIP Citation Database) from establishment of these database to February 2015. The combined relative risk (RR) of H. pylori eradication rate and the rate of side effects were analyzed. Sub-group and sensitivity analysis was performed, and the publication bias was also tested. 
 RESULTS: A total of 9 studies including 1 644 cases were identified. The H. pylori eradication rate was 79.5% in fermented milk products combined with routine therapy, and 67.0% in routine therapy. The combined RR of H. pylori eradication rate was 1.186 (95% CI 1.118-1.257), and the combined RR of total side effects was 0.706 (95% CI 0.373-1.340).
 CONCLUSION Cultured milk products as adjunctive therapy is effective in improving the eradication rate during eradication therapy for H. pylori. However, it could not effectively decrease the risk of side effects.
