Objective:This study aims to analyze the provincial policy text of separate payment for National medical insurance negotiated drugs,summarize the key measures and characteristics,and provide reference for the formulation and improvement of separate payment policies in various provinces.Methods:The retrieved policy texts were analyzed by searching the websites of the medical security bureaus of various provinces,municipalities,and autonomous regions.Results:There are differences in the separate payment policies of different provinces in terms of catalogue publishing,catalogue selection,drug management,policy treatment level and policy cohesion.Conclusion:The separate payment policy is the key driver of Joint Reformation for Public Health Services,Medical Insurance,and Medical Production-Circulation.And all provinces should balance the various policy elements of the separate payment catalogue,deal with the control of medical insurance funds and patients'sense of gain,and clarify the relationship between the separate payment policy and support the development of innovative drugs,so as to reduce the obstacles of Joint Reformation for Public Health Services,Medical Insurance,and Medical Production-Circulation.

Tetrandrine(TET),a natural bisbenzyl isoquinoline alkaloid extracted from Stephania tetrandra S.Moore,has diverse pharmacological effects.However,its effects on melanoma remain unclear.Cellular prolif-eration assays,multi-omics analyses,and xenograft models were used to determine the effect of TET on melanoma.The direct target of TET was identified using biotin-TET pull-down liquid chromatograph-mass spectrometry(LC-MS),cellular thermal shift assays,and isothermal titration calorimetry(ITC)analysis.Our findings revealed that TET treatment induced robust cellular autophagy depending on activating transcription factor 6(ATF6)-mediated endoplasmic reticulum(ER)stress.Simultaneously,it hindered autophagic flux by inducing cytoskeletal protein depolymerization in melanoma cells.TET treatment resulted in excessive accumulation of reactive oxygen species(ROS)and simultaneously triggered mitophagy.Sirtuin 5(SIRT5)was ultimately found to be a direct target of TET.Mechanistically,TET led to the degradation of SIRT5 via the ubiquitin(Ub)-26S proteasome system.SIRT5 knockdown induced ROS accumulation,whereas SIRT5 overexpression attenuated the TET-induced ROS accumula-tion and autophagy.Importantly,TET exhibited anti-cancer effects in xenograft models depending on SIRT5 expression.This study highlights the potential of TET as an antimelanoma agent that targets SIRT5.These findings provide a promising avenue for the use of TET in melanoma treatment and underscore its potential as a therapeutic candidate.

Objective To evaluate the predictive factors for failure of non-invasive positive pressure ventilation (NIPPV) in immunosuppressed patients with acute respiratory failure (ARF). Methods The clinical data of 118 immuno-deficient patients treated with NIPPV in the respiratory and intensive care unit (RICU) of the First Affiliated Hospital of Xinjiang Medical University from January 2012 to August 2017 were retrospectively analyzed. The patients were divided into a non-endotracheal intubation (ETI) group (n = 62) and ETI group (n = 56) according to whether ETI was performed during the hospitalization period or not. Each observed indicator was analyzed by univariate analysis, and factors leading to failure of NIPPV were further analyzed by Logistic regression. Receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of risk factors for failure of NIPPV in immunosuppressed patients with ARF. Results The non-intubation rate for NIPPV in immunosuppressed patients was 50.8% (60/118). Compared with the non-ETI group, the body temperature, pH value in the ETI group were significantly increased, the partial pressure of arterial carbon dioxide (PaCO2) was significantly decreased, the ratio of oxygenation index (PaO2/FiO2) < 100 mmHg (1 mmHg = 0.133 kPa), acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ) score ≥ 20, and the number of cases requiring catecholamine were significantly increased, the mortality was significantly increased. Multivariate Logistic regression analysis showed that the APACHE Ⅱ score ≥ 20 [odds ratio (OR) = 15.274, 95% confidence internal (95%CI) = 2.175-107.252, χ2= 7.516, 1 = 0.006], PaO2/FiO2< 100 mmHg (OR = 0.075, 95%CI = 0.014-0.408, χ2= 8.968, 1 = 0.003), and need for catecholamine (OR = 35.736, 95%CI = 6.974-183.124, χ2= 18.400, 1 < 0.001) were independent risk factors for failure of NIPPV. ROC curve analysis showed that the APACHE Ⅱ score ≥ 20 and PaO2/FiO2< 100 mmHg could predict failure of NIPPV, the area under ROC curve (AUC) of the APACHE Ⅱ score ≥ 20 was 0.787, the sensitivity was 83.93%, the specificity was 69.35%, the positive predict value (PPV) was 71.21%, the negative predict value (NPV) was 82.69%, the positive likelihood ratio (PLR) was 2.74, the negative likelihood ratio (NLR) was 0.23, and Youden index was 0.53; the AUC of PaO2/FiO2< 100 mmHg was 0.757, the sensitivity was 80.65%, the specificity was 66.07%, the PPV was 68.18%, the NPV was 78.85%, the PLR was 2.38, the NLR was 0.29, and Youden index was 0.47. Conclusions 50.8% of immunocompromised and ARF patients treated with NIPPV did not require ETI, which is independent of the etiology of ARF. APACHE Ⅱ score ≥ 20, PaO2/FiO2<100 mmHg, and the need for catecholamine are predictive factors for failure of NIPPV in immunocompromised patients.

OBJECTIVEWe investigate the magnitudes of waveform changes of arterial blood gas (ABG) in patients with heart failure.

METHODSFive patients with heart failure were selected, continuous collecting radial artery blood and measured PaO2, PaCO2, pHa and Sao2. We selected two typical breaths cycles of waveform changes of ABG from each patient for data analysis. Comparison of the adjacent highest and lowest values to verify the presence of a periodic waveform changes of ABG, and in addition, we used t test to analysis the range of waveform changes of ABG in patients with heart failure and patients with normal cardiac function and compared whether the difference between them.

RESULTSThe 5 patients (2 surgical and 3 ICU) with heart failure, were 4 male and 1 female, (69 ± 7)year, (169 ± 10) cm, (75 ± 19)kg, LVEF = (38 ± 3)%. The heart beat numbers for full blood into the blood sampling pipe were 17 ± 2, and all covered more than 2 breath cycles. There were significant changes of PaO2, PaCO2, [H+]a and SaO2 (P < 0.05). The magnitudes of changing PaO2, PaCO2, [H+]a and Sao2 were (7.94 ± 2.02)mmHg, (1.18 ± 0.56)mmHg, (0.54 ± 0.17)nmol/L and (0.21 ± 0.07)%, and they were (6.1 ± 1.5)%, (3.2 ± 1.5)%, (1.5 ± 0.5)% and (0.2 ± 0.1)% from their mean respectively. Even these magnitudes fo all ABG parameters were trendily lower than those of patients with normal cardiac function, but only PaO2 and [H+]a were significant (P < 0.05).

CONCLUSIONUsing this simple continuous beat-by-beat arterial blood sampling method, we obtained a clear evidence of periodic waveform of ABG parameters following by breath cycle in patients with heart failure, but the magnitude trendily be decreased.
