Primary diffuse large B-cell lymphoma in cavernous sinus: report of 1 case and review of literature / 白血病·淋巴瘤

Objective:To investigate the clinicopathological features, treatment programs and prognosis of patients with primary diffuse large B-cell lymphoma (DLBCL) in cavernous sinus.Methods:The clinical data of a patient with primary DLBCL in cavernous sinus who were admitted to Wuhan No.1 Hospital in December 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 63-year-old female who underwent resection of the cavernous sinus lesion, and the pathological diagnosis was DLBCL. The patient received 6 courses of R-CHOP regimen chemotherapy, lumbar puncture + intrathecal injection of chemotherapy drugs, and twice additional rituximab immunochemotherapy, and no tumor cells were found in the results of liquid-based thin layer cytology for cerebrospinal fluid exfoliated cells; twice magnetic resonance imaging (MRI) re-examination after the operation showed no recurrence and adjacent metastasis of the tumor. The patient's symptoms were significantly improved without residual neurological sequelae.Conclusions:Primary DLBCL in cavernous sinus is rare in clinical practice, early diagnosis is crucial for the prognosis of patients, and different protein expression may indicate the prognosis. Biopsy, complete resection of the tumor under the premise of preserving important anatomical structures and functions, and standardized chemotherapy combined with intrathecal injection local chemotherapy can effectively prolong the survival time of patients and improve the quality of life.

Research on price-formation in the big data diagnosis-intervention packet / 中华医院管理杂志

Objective:To explore the price formation method and price standard in the big data diagnosis-intervention packet.Methods:The expenditure data and income data of 95 medical institutions in Shanghai in 2018 were used for analysis, including 33 municipal hospitals and 62 district hospitals. After using the standardized data of disease score, the medical institutions in the region were divided into four quadrants with the regional average of unit price per index and cost per index as the coordinate axis. The best quadrant of income and cost was found out, namely the high quality range. The geometric center was calculated in the high quality range, and the unit price per index of the geometric center was taken as the cost standard.Results:For the district hospitals, there were 20 hospitals in the first quadrant, 8 in the second quadrant, 24 in the third quadrant and 10 in the fourth quadrant; For the municipal hospitals, there were 7 hospitals in the first quadrant, 5 in the second quadrant, 12 in the third quadrant and 9 in the fourth quadrant. In the third quadrant, the average income and cost of medical institutions were lower than the average of the city, and the income could cover the cost. The third quadrant was the high quality range. The unit price per index of the third quadrant geometric center of district hospitals was 14 115.4 yuan, and that in municipal hospitals was 15 559.1 yuan, which could be used as the corresponding cost standard.Conclusions:The price discovery mechanism based on objective data and high-quality interval geometric center method can remove the impact of unreasonable charges or unreasonable behavior on medical income, and reflect the guidance of the standard price of medical insurance payment.

The big data diagnosis-intervention packet payment method: experience from Shanghai and Guangzhou / 中华医院管理杂志

Medical insurance payment model is transforming from project-based purchases to service bundle-based strategic purchases. The new form of bundled purchases should found on a scientifically-led design process of such bundles. The core to bundled purchase would be the payment standard, and the key to its success would be process control. Establishment of such a foundation, a core, and a key, would promote the current price standards, and lead service providers to a standardized medical service standard, so as to ensure a precise rewarding system of payment and service. The big data diagnosis-intervention packet(DIP)is able to fulfill mentioned ambitions by integrating insurance payment and supervision into one management. DIP is a full-process payment mode that encompasses pre-service estimation, in-service process control, post-service grading, and resource allocation. It is an innovative practice in line with China′s national conditions for the modern governance of medical security and medical services.

CT perfusion evaluation before and after revascularization in adult patients with Moyamoya disease / 国际脑血管病杂志

Objective To investigate the application value of CT perfusion (CTP) imaging for the revascularization treatment in adult patients with Moyamoya disease.Methods Adult patients with Moyamoya disease underwent revascularization in the Department of Neurosurgery,Wuhan No.1 Hospital from July 2009 to December 2016 were analyzed retrospectively.CTP and clinical evaluation were performed before and after 3-6 months of procedure.The modified Rankin Scale (mRS) was used to assess the functional outcomes.Results A total of 20 patients were enrolled in the study,including 9 females and 11 males,aged 29 to 73 years,with an average of 53.5 years.The initial symptom was ischemic stroke in 10 patients,transient isehemic attack in 7 patients,and hemorrhagic stroke in 3 patients.All patients underwent superficial temporal artery-middle cerebral artery bypass grafting plus encephalomyo-synangiosis under general anesthesia.All patients have different degrees of improvement in cerebral blood flow after procedure,and the CTP parameters were significantly improved compared with those before procedure (all P ＜0.05).The clinical symptoms were significantly improved in 3 cases (15％) and recovered in 13 cases (65％) at 6 months after procedure.The proportion of the mRS score 0-2 was significantly higher than that before procedure (90.0％ [18/20] 对 50.0％ [10/20];x2 =7.619,P =0.006).Conclusion CTP can evaluate the cerebral perfusion status in various vascular areas through hemodynamic parameters in early stage,which can effectively guide the operation mode of Moyamoya disease,and evaluate the changes of cerebral perfusion status after procedure as a means of follow-up of the disease.

Expression changes of indoleamine 2,3-dioxy-genase in the hippocampus of rat with post-traumatic stress disorder / 中华行为医学与脑科学杂志

Objective To observe the expression of indoleamine 2,3-dioxy-genase(IDO) in hippocampus of rats with posttraumatic stress disorder (PTSD) and the protective effect of IDO inhibitor on neurons,and to explore the role of IDO in the pathogenesis of PTSD.Methods Adult male Wistar rats were randomly divided into the normal control group,PTSD model group and IDO inhibitor treatment group.The expression of IDO was detected by immunohistochemistry,RT-PCR and Western-blot.The apoptosis of rat hippocampal neurons was assayed by Tunel staining.Tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were detected by ELISA.Moreover behavioral evaluation was performed,including central residence time,percentage of open arm residence time and stage latency.Results Comparing with the control group,PTSD rats showed decreased central residence time ((22.65± 1.54)s),decreased percentage of open arm residence time((10.55± 1.96) ％),prolonged stage latency ((56.38±4.21) s) (P＜0.05),increased TNF-α ((8.58±0.6) pg/ml),IL-6 ((15.72±1.42) pg/ml) and IDO mRNA (0.8278±0.0796),increased IDO protein (1.2329±0.1148) expression and apoptosis rate ((81.47± 6.86) ％) in hippocampus (P＜ 0.05) (P＜ 0.05).However,rats treated with IDO inhibitor showed increased central residence time((30.78±3.20) s),increased percentage of open arm residence time ((10.55± 1.96)％),shortened stage latency ((56.38 4.21) s),meanwhile reduced expression of TNF-α((3.69±0.41) pg/ml),IL-6((7.45±0.58) pg/ml),IDO mRNA(0.2236 ±0.0387) and IDO protein(0.4235±0.0411) was detected in hippocampus(P＜0.05).Apoptosis rate ((42.54± 3.98)％) was also decreased in hippocampus(P＜0.05).Conclusion The content of TNF-α,IL-6 and IDO are increased significantly in the hippocampus of PTSD rats.IDO may participate in the pathogenesis of PTSD,and the IDO inhibitor may play a neuroprotective role in hippocampus of PTSD.
