Application values of multiple detection methods of bone marrow in newly diagnosed multiple myeloma / 白血病·淋巴瘤

Objective:To investigate the application values of bone marrow morphology, bone marrow immunohistochemistry, flow cytometry, fluorescence in situ hybridization (FISH) and cytogenetic testing in newly diagnosed multiple myeloma.Methods:A total of 280 patients with multiple myeloma who were newly diagnosed in Tianjin KingMed Diagnosis Center from September 2018 to August 2019 were collected. The bone marrow biopsy was carried out according to the routine method, and bone marrow morphology, bone marrow immunohistochemistry, flow cytometry immunophenotyping, FISH and cytogenetic testing were performed. The detection results of each method were compared.Results:In 280 patients, the bone marrow immunohistochemistry results showed that the median ratio of plasma cells was higher than those of bone marrow morphology (20 cases, 0.675 vs. 0.300) and flow cytometry (47 cases, 0.650 vs. 0.147), and the differences were statistically significant ( Z = -3.883, P < 0.01; Z = -5.947, P < 0.01). Flow cytometry results showed that the positive rates of CD38, CD138, κ, λ, CD56 and CD19 were 100.0% (280/280), 100.0% (280/280), 57.5% (161/280), 42.5% (119/280), 62.1% (174/280) and 19.3% (54/280); bone marrow immunohistochemistry results showed that the positive rates of CD38, CD138, κ, λ and CD56 were 98.9% (277/280), 98.2% (275/280), 57.5% (161/280), 42.5% (119/280) and 62.1% (174/280); there was no statistical difference between the two detection methods in the detection coincidence rate of the same detection index (all P > 0.05). Among patients who underwent FISH detection, the detection rate of gene abnormalities was 69.9% (93/133); the detection rate of abnormalities by direct fluorescence in situ hybridization (D-FISH) was 42.9% (57/133); the detection rate of abnormalities by CD138 immunomagnetic sorting myeloma cells (MACS)-FISH was 82.7% (110/133). Among patients who underwent G-band karyotyping, the detection rate of abnormal karyotype was 38.5% (85/221). FSIH, especially MACS-FISH, had a higher detection rate of cytogenetic abnormalities than G-band karyotyping, and the difference was statistically significant ( χ2 = 65.697, P < 0.05). Conclusion:The comprehensive application of bone marrow morphology, bone marrow immunohistochemistry, flow cytometry, FISH (especially MACS-FISH), cytogenetic testing and other detection methods is more helpful for the diagnosis of multiple myeloma, and may be useful for prognostic judgment.

Hospitalization days and costs of patients with acute cholecystitis in different departments by DRGs / 中华医院管理杂志

Objective To analyze the differences in hospitalization days and costs of patients with acute cholecystitis in different departments or diagnosis related groups ( DRGs ), and provide scientific references for clinical medical management. Methods All the medical record homepages of the patients with acute cholecystitis were selected from a tertiary hospital from January 2017 to December 2017. The hospital analysis system of DRGs was used to calculate the classification results of DRGs. The Kruskal-Wallis H test was used to analyze the differences in hospital stays and costs between different DRGs or departments. Results The average length of stay was the shortest and the hospitalization cost in the department of hepatobiliary surgery was lower than other departments among patients with surgery and non-surgical(all P<0.05); The average length of stay at the department of hepatobiliary surgery was lower than the same other DRGs groups, namely the department of digestive medicine and gastrointestinal surgery(all P<0.05). There was no significant difference in the cost of " acute biliary tract disease with complications" between the various departments(P>0.05). The average cost in the department of hepatobiliary surgery was the lowest, and the average cost of gastrointestinal surgery was the highest in two DRGs of " acute biliary disease without complications and concomitant symptoms" and " laparoscopic cholecystectomy without common bile duct exploration" ( all P < 0.05 ). Conclusions Department of hepatobiliary surgery was better than other departments in the treatment of acute cholecystitis. Medical institutions should follow the principle of special treatment to reduce interdisciplinary patients and improve the professional competitiveness of the department.

Management practice and thinking of different DRGs grouped patients in clinical pathway / 中华医院管理杂志

Objective To analysis the clinical pathway management efficiency under different DRG groups, for a basis for further optimizing clinical pathway management. Methods The retrospective analysis method was used to compare the average length of stay, sub-average costs, and drug proportions of patients with different DRGs in the same clinical pathway. Shapiro-Wilk was used to detect the normality of the samples, t test was used to analyze measurement data conformed to the normal distribution, non-parametric test was used to analyze the abnormal distribution data, and enumeration data was detected by using chi-square test. Results For patients with a clinical pathway of bronchial pneumonia, patients with severe complications and concomitant symptoms had no significant difference in mean hospitalization and sub-costs, regardless of whether they completed or entered the clinical pathway ( P >0.05). For the other two DRG patients, the difference between the average length of stay, sub-average costs, and the proportion of medications for patients who completed the clinical pathway and withdrew from or did not complete the clinical pathway was significant(P<0.05). In the severe surgical group, the length of stay and average cost for patients who completed the clinical pathway were lower than those who exited or did not enter the clinical pathway(P<0.05). Conclusions Patients with different severity of DRGs should be cautious when they are enrolled in the clinical pathway.

Research Advance on Tuina and Postpartum Milk Secretion / 针灸推拿医学（英文版）

Objective: To analyze the relevant literature regarding the effect of tuina on postpartum milk secretion and thus summarize the clinical rules on tuina for lactation disorder. Method: Investigate the relationship between tuina and postpartum milk secretion for four aspects, including the initial time of lactation, level of serum prolactin, volume of lactation, and Chinese medicine's understanding of tuina on milk secretion. Result and Conclusion: Tuina on breasts after childbirth can speed and promote lactation. This has been proved by clinical practice over the past hundreds of years, along with modern laboratory and scientific research. This method, therefore, is of great significance in obstetrical nursing.
