[Objective] To explore the strategy of blood management in patients with massive transfusion in the frigid plateau region. [Methods] The treatment process of a patient with liver rupture in the frigid plateau region was analyzed, and the blood management strategy of the frigid plateau region was discussed in combination with the difficulties of blood transfusion and literature review. [Results] The preoperative complete blood count (CBC) test results of the patient were as follows: RBC 3.14×10¹²/L, Hb 10⁶ g/L, HCT 30.40%, PLT 115.00×10⁹/L; coagulation function: PT 18.9 s, FiB 1.31 g/L, DD > 6 μg/mL, FDP 25.86 μg/mL; ultrasound examination and imaging manifestations suggested liver contusion and laceration / intraparenchymal hematoma, splenic contusion and laceration, and massive blood accumulation in the abdominal cavity; it was estimated that the patient's blood loss was ≥ 2 000 mL, and massive blood transfusion was required during the operation; red blood cell components were timely transfused during the operation, and the blood component transfusion was guided according to the patient's CBC and coagulation function test results, providing strong support and guarantee for the successful treatment of the patient. The patient recovered well after the operation, and the CBC test results were as follows: RBC 4.32×10¹²/L, Hb 144 g/L, HCT 39.50%, PLT 329.00×10⁹/L; coagulation function: APTT 29.3 s, PT 12.1 s, FiB 2.728 g/L, DD>6 μg/mL, FDP 25.86 μg/mL. The patient was discharged after 20 days, and regular follow-up reexamination showed no abnormal results. [Conclusion] Individualized blood management strategy should comprehensively consider the patient’s clinical symptoms, the degree of hemoglobin decline, dynamic coagulation test results and existing treatment conditions. Efficient and reasonable patient blood management strategies can effectively improve the clinical outcomes of massive transfusion patients in the frigid plateau region.

Objective:To explore the standardized performance of a FISH probe before clinical detection.Methods:The probe sensitivity and specificity of ETV6/RUNX1 were analyzed via interphase and metaphase FISH in 20 discarded healthy bone marrow samples. The threshold system of the probe was established using an inverse beta distribution, and an interpretation standard was established. Finally, a parallel-controlled polymerase chain reaction detection study was conducted on 286 bone marrow samples from patients at our hospital. The clinical sensitivity, specificity, and diagnostic coincidence rate of ETV6/RUNX1 FISH detection were analyzed, and the diagnostic consistency of the two methods was analyzed by the kappa test.Results:The probe sensitivity and specificity of the ETV6/RUNX1 probe were 98.47% and 100%, respectively. When 50, 100, and 200 cells were counted, the typical positive signal pattern cutoffs were 5.81%, 2.95%, and 1.49%, respectively, and the atypical positive signal pattern cutoffs were 13.98%, 9.75%, and 6.26%, respectively. The clinical sensitivity of FISH was 96.1%, clinical specificity was 99.6%, diagnostic coincidence rate was 99.00%, diagnostic consistency test kappa value was 0.964, and P value was <0.001.Conclusion:For FISH probes without a national medical device registration certificate, standardized performance verification and methodology performance verification can be performed using laboratory developed test verification standards to ensure a reliable and accurate reference basis for clinical diagnosis and treatment.

Objective:To assess the clinical value of metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid in pathogenic diagnosis of neurological infectious disease.Methods:Patients who were clinically diagnosed with infectious encephalitis and meningitis and treated in Department of Neurology, Affiliated Hospital of Chifeng University from March 2018 to September 2019 were retrospectively analyzed, including the clinical characteristics and data of mNGS and traditional laboratory test of pathogens.Results:Totally 104 patients with infectious encephalitis and meningitis were eligible for enrollment, and mNGS detected 22 bacterial species(22/104,21.15%), 24 viral species (24/104,23.08%), one fungal species (1/104,0.96%), one parasitic species (1/104,0.96%) and one mycoplasma species (1/104,0.96%).The three leading positive detections were varicella-zoster virus ( n=19), streptococcus ( n=7) and Mycobacterium tuberculosis ( n=4). Combined with traditional pathogen detection methods, clinical manifestations, final diagnosis and treatment results, the number of cases diagnosed by mNGS was 49 cases. The positive rate of the mNGS was 47.12% (49/104).False positives occurred in 21 (20.19%) patients. False negatives occurred in 34 (32.69%) patients. Conclusions:mNGS is more sensitive in evaluating the pathogens causing the infectious encephalitis and meningitis. It has advantages in accurate diagnosis of infectious encephalitis and meningitis.

Objective To develop a diagnostic model based on deep neural network for intelligent discrimination of thyroid function. Methods A total of 1616 patients ( 283 males, 1333 females, average age:52 years) who underwent thyroid imaging between May 2016 and June 2018 were selected. According to the clinical diagnosis, the 1616 cases included 299 normal thyroid cases, 876 hyperthyroidism cases and 441 hypothyroidism cases. Feature extraction and learning training were performed on 1000 training set sam-ples by two deep neural network models ( AlexNet;deep convolution generative adversarial networks ( DCGAN) ) using deep learning algorithm. Performance verifications were implemented on 616 test set samples. The con-sistency between the verification results of the two models and the clinical diagnosis was analyzed by Kappa test. Meanwhile, the time advantage of the intelligent diagnosis models was analyzed. Results The average diagnostic time of AlexNet model was 1 s/case, and the classification accuracy for normal thyroid, hyperthy-roidism, hypothyroidism were 82.29％(79/96), 94.62％(369/390), 100％(130/130), respectively. The Kappa value between results of AlexNet model and clinical diagnosis was 0.886 ( P<0.05) . The average di-agnostic time of DCGAN model was 1 s/case, and the classification accuracy for normal thyroid, hyperthy-roidism, hypothyroidism were 85.42％(82/96), 95.64％(373/390), 99.23％(129/130), respectively. The Kappa value between results of DCGAN model and clinical diagnosis was 0.904 ( P<0.05) . Conclusion The deep neural network intelligent diagnosis model can quickly determine the functional status of thyroid gland in thyroid imaging, and it has a high recognition accuracy, thus providing a new method for thyroid image review.

Objective To analyze the main practices of capitation payment system reform in the case areas and put forward enlightenments and suggestions in this regard. Methods The implementation practices of the case areas were summarized, and descriptive statistical analysis was carried out on the implementation effects. Results By analyzing the effectiveness of the case areas′reform, it was found that the case areas are curbing the excessive growth of medical expenses (for example, outpatient fees per visit of Dingyuan county-level hospitals decreased from 245.11 yuan in 2015 to 218.40 yuan in 2017), increasing the actual compensation ratio of residents ( for example, the actual compensation ratio of Funan increased from 59.80% in 2015 to 63.28% in 2017), forming a medical treatment pattern within the county (for example, out-of-county compensation ratio in Dingyuan decreased from 37.38% in 2015 to 31.13% in 2017), achieving double-way referrals (for example, the number of referrals to superior hospitals of Jimo increased from 98 in 2015 to 328 in 2017), improving the subsidence of quality services, and controlling the risks of medical insurance funds. Conclusions At present, the reform of the case areas has been implemented steadily and achieved results. It is recommended to further improve such aspects as reform coordination, insurance standard setting, incentive mechanism establishment, and leadership to ensure the reform progress.

Pilot areas have achieved initial success in capitation reform. On the other hand, challenges remain unsolved in terms of practical pathways, change of national medical insurance management system, related measures, incentives and allocative mechanism for implement of the reform. With the concerning on progress, practice, effects and challenges of typical areas, this article established an institutional framework. On such basis, we propose to design and refine a scheme in terms of 5 aspects, namely strengthening the basic medical care packages′financing, setting contents and standard of the basic medical care packages rationally, establishing effective evaluation system and formulating supporting measures.

Objective The aim of this study was to compare the short-term and long-term prognostic significance of dif-ferent systemic inflammatory scores in patients with gastric cancer:neutrophil lymphocyte ratio(NLR) and platelet lymphocyte ratio ( PLR). Methods The clinical data of 240 patients with gastric cancer who underwent radical surgery were retrospectively analyzed. The relationship between NLR,PLR,glasgow prognostic score( GPS) and clinicopathological characteristics and perioperative compli-cations were compared. Survival analysis was performed using Kaplan-Meier survival analysis. The Log-rank methods were used to test the difference significance,and the multivariate analysis was performed using the Cox regression risk model. Results Patients in the high NLR and PLR groups were older,had a high GPS,deep tumor infiltration,more lymph node metastasis,and a late TNM stage (P<0. 05). The rate of positive margin in the high NLR group was higher(P<0. 05). Patients in the high NLR and PLR groups re-quired significantly higher transfusion rates than those in the low NLR and PLR groups(P<0. 05),and the high NLR group had more postoperative complications(P<0. 05). Univariate analysis showed that age,GPS,tumor location,tumor infiltration depth,lymph node metastasis status,TNM stage,vascular tumor thrombus,nerve infiltration,NLR and PLR were associated with postoperative survival of gastric cancer patients(P<0. 05). The overall survival(OS)in high NLR and high PLR groups was lower than that of low NLR and low PLR groups(P=0. 018 and P<0. 001). Cox regression analysis showed GPS and lymph node metastasis were independent prog-nostic factors of OS(P<0. 001 and P=0. 002). Conclusion Preoperative systemic inflammatory scores NLR and PLR are prognos-tic factors affecting the preoperative clinical outcomes of gastric cancer. It is recommended to be used in combination with other prog-nostic indicators for routine use in the prognosis of patients undergoing radical gastrectomy.
