Objective:To observe the clinical effect of internal administration of Traditional Chinese Medicine (TCM) and external application of hot election bag combined with acupuncture on urinary retention after stroke with kidney qi deficiency type.Methods:A total of 106 patients admitted to Chengde Hospital of Traditional Chinese Medicine from January 2017 to December 2020 who met the inclusion criteria were randomly divided into 2 groups according to the random number table method, with 53 in each group. The control group was treated with conventional western medicine therapy and bladder function training, while the observation group was treated with TCM, acupuncture and external application on the basis of the control group. Both groups were treated for 28 days. Before and after treatment, TCM syndrome scores were performed, and the maximum urinary capacity and residual urine volume were recorded by abdominal B-ultrasound to evaluate the bladder function of the patients. The improvement time of urinary pain, first urination time, catheter indwelling time, length of hospital stay and adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate was 96.2% (51/53) in the observation group and 84.9% (45/53) in the control group, and the difference between the two groups was statistically significant ( χ2=3.98, P=0.046). The residual urine volume of the observation group after treatment [(54.23±6.23) ml vs. (91.24±11.25) ml, t=20.95] was significantly lower than that of the control group ( P<0.01), and the maximum urinary bladder volume [(366.23±30.23) ml vs. (259.63±26.23) ml, t=19.39] was significantly higher than that of the control group ( P<0.01). After treatment, the TCM syndrome score of the observation group was significantly lower than that of the control group ( t=13.25, P<0.01), and the bladder function score of the observation group was significantly lower than that of the control group ( t=13.53, P<0.01). The improvement time of urinary pain, first urination time, catheter indwelling time and hospital stay in the observation group were significantly lower than those in the control group ( t=5.73, 17.91, 6.76, 9.67, all Ps <0.01). No adverse reactions occurred in the two groups during treatment. Conclusion:The combination of TCM, hot compress therapy and acupuncture plus routine therapy can treat the patients with urinary retention after stroke and kidney qi deficiency type with good bladder function, improved symptoms and fast recovery and safety.

Objective:To investigate the diagnostic value of nucleic acid matrix-assisted laser desorption ionization-time of flight mass spectrometry(MALDI-TOF MS)in sputum smear-negative patients with nontuberculous Mycobacterial(NTM)pulmonary disease.Methods:Clinical data of 123 patients suspected of NTM pulmonary disease admitted in Public Health Clinical Center Affiliated to Shandong University between July 2022 and November 2023 were retrospectively analyzed. Bronchoalveolar lavage fluid(BALF)specimens were collected for MALDI-TOF MS assay and MGIT 960 culture. The diagnostic efficacy of MALDI-TOF MS for NTM pulmonary disease in patients with negative sputum smears for acid-fast bacilli was evaluated with receiver operating characteristic(ROC)curve. Statistical analysis was performed using SPSS 26.0 software and MedCalc statistical software.Results:Diagnosis of NTM pulmonary disease was finally confirmed in 66 out of the 123 suspected patients. It took 8 to 24 h for MALDI-TOF MS to identify NTM species and resistance. By MALDI-TOF MS,72 NTM strains were identified,with the Mycobacterium avium complex being the most prevalent(34 strains,47.22%),followed by the Mycobacterium abscessus complex(13 strains,18.06%);resistance to macrolides was detected in 6 cases,while no resistance to aminoglycosides was found. It took 9 to 45 days for BALF MGIT 960 culture to identify NTM,and took 7 to 15 days for NTM typing and drug sensitivity testing. By BALF MGIT 960 culture,28 NTM strains were identified;and 1 case was found to be resistant to macrolides. Using confirmed diagnosis as the gold standard,MALDI-TOF MS demonstrated higher sensitivity,negative predictive value,and agreement rate compared to MGIT 960 culture(84.85% vs. 42.42%,81.13% vs. 56.32%,80.49% vs. 62.60%, χ2=25.667,8.998,9.664, P<0.05 or <0.01). The area under ROC curve(AUC)for MALDI-TOF MS was significantly higher than that of MGIT 960 culture(0.801 vs. 0.642, Z=3.300, P=0.001). Conclusion:Compared to MGIT 960 culture,MALDI-TOF MS exhibits superior diagnostic efficiency in detecting NTM pulmonary disease in patients with acid-fast bacilli smear-negative sputum,with advantage of rapidly identifying NTM species and resistance.
