ObjectiveTo observe the dose of methadone and the compliance of patients to the methadone maintenance treatment(MMT).MethodsWe analyzed the status of 69 patients who were addicted to opiate medication and 44 patients who dropped out in our clinic until July 31,2010.ResultsThere was no significant relationship between patients' urine test and the dose.Crime caused the patients who dropped out.The percentage of positive urine did not decline as the dose increased,but the rate of patients who dropped and the number of positive urine test showed a significant correlation( r =0.523 P =0.000).Crime was the main reason that affected the compliance to MMT and caused dropping out.ConclusionThe use of MMT dose should be individualized.

Objective To observe therapeutic effects of acupoint catgut embedding therapy on ulcerative colitis.Methods 55 cases of ulcerative colitis were randomly recruited into a treatment group and a control group. The treatment group was treated with catgut embedding, and the control group was treated with oral administration of salicylazosul fapyridine. Results The therapeutic effect of the treatment group was better than those of the control group (P=0.002＜0.05). Conclusion Acupoint catgut embedding therapy has a better therapeutic effect on ulcerative colitis.

Objective:To screen out the differentially regulated metabolites by the analysis of serum metabolic fingerprints, and to provide potential biomarkers for diagnosis of lung cancer.Methods:A total of 228 subjects were enrolled in Changhai Hospital from January 27, 2021 to June 4, 2021, including 97 newly diagnosed lung cancer patients and 131 healthy individuals. Serum samples were collected from the enrolled cohort according to a standard procedure, and the enrolled cohort was divided into a training set and a completely independent validation set by stratified random sampling. The metabolic fingerprints of serum samples were collected by previously developed nano-assisted laser desorption/ionization mass spectrometry (nano-LDI MS). After age and gender matching of the training set, a diagnostic model based on serum metabolic fingerprints was established by machine learning algorithm, and the classification performance of the model was evaluated by receiver operating characteristic (ROC) curve.Results:Serum metabolic fingerprint for each sample was obtained in 1 minute using a novel nano-LDI MS, with consumption of only 1 μl original serum sample. For the training set, the area under ROC curve (AUC) of the constructed classifier for diagnosis of lung cancer was 0.92 (95% CI 0.87-0.97), with a sensitivity of 89% and specificity of 89%. For the independent validation set, the AUC reached 0.96 (95% CI 0.90-1.00) with a sensitivity of 91% and specificity of 94%, which showed no significant decrease compared to training set. We also identified a biomarker panel of 5 metabolites, demonstrating a unique metabolic fingerprint of lung cancer patients. Conclusion:Serum metabolic fingerprints and machine learning were combined to establish a diagnostic model, which can be used to distinguish between lung cancer patients and healthy controls. This work sheds lights on the rapid metabolic analysis for clinical application towards in vitro diagnosis.
