Objective:To develop and evaluate a nomogram prediction model for the 3-month mortality risk of patients with sepsis-associated acute kidney injury (S-AKI).Methods:Based on the American Medical Information Mart for Intensive Care-Ⅳ (MIMIC-Ⅳ), clinical data of S-AKI patients from 2008 to 2021 were collected.Initially, 58 relevant predictive factors were included, with all-cause mortality within 3 months as the outcome event. The data were divided into training and testing sets at a 7∶3 ratio. In the training set, univariate Logistic regression analysis was used for preliminary variable screening. Multicollinearity analysis, Lasso regression, and random forest algorithm were employed for variable selection, combined with the clinical application value of variables, to establish a multivariable Logistic regression model, visualized using a nomogram. In the testing set, the predictive value of the model was evaluated through internal validation. The receiver operator characteristic curve (ROC curve) was drawn, and the area under the curve (AUC) was calculated to evaluate the discrimination of nomogram model and Oxford acute severity of illness score (OASIS), sequential organ failure assessment (SOFA), and systemic inflammatory response syndrome score (SIRS). The calibration curve was used to evaluate the calibration, and decision curve analysis (DCA) was performed to assess the net benefit at different probability thresholds.Results:Based on the survival status at 3 months after diagnosis, patients were divided into 7?768 (68.54%) survivors and 3?566 (31.46%) death. In the training set, after multiple screenings, 7 variables were finally included in the nomogram model: Logistic organ dysfunction system (LODS), Charlson comorbidity index, urine output, international normalized ratio (INR), respiratory support mode, blood urea nitrogen, and age. Internal validation in the testing set showed that the AUC of nomogram model was 0.81 [95% confidence interval (95% CI) was 0.80-0.82], higher than the OASIS score's 0.70 (95% CI was 0.69-0.71) and significantly higher than the SOFA score's 0.57 (95% CI was 0.56-0.58) and SIRS score's 0.56 (95% CI was 0.55-0.57), indicating good discrimination. The calibration curve demonstrated that the nomogram model's calibration was better than the OASIS, SOFA, and SIRS scores. The DCA curve suggested that the nomogram model's clinical net benefit was better than the OASIS, SOFA, and SIRS scores at different probability thresholds. Conclusions:A nomogram prediction model for the 3-month mortality risk of S-AKI patients, based on clinical big data from MIMIC-Ⅳ and including seven variables, demonstrates good discriminative ability and calibration, providing an effective new tool for assessing the prognosis of S-AKI patients.

The theory of static and dynamic combination coincides with the effect of osteoblast stress, although there are few articles on molecular biology about the theory in recent years. The treatment of static and dynamic combination theory for fractures and other orthopedic disorders is to use the localized stress fracture, and the stress controls bone formation results through afffecting proliferation of osteoblast differentiation, which has proved by relevant experimental evidence. This article discussed the molecular biology basis about the correlation between theory of static and dynamic combination and osteoblast proliferation and differentiation by stress stimulation.

Recent studies have shown that TCM treatment for bone metabolic diseases, such as steroid-induced avascular necrosis of the femoral head, has definite efficacy and has received extensive attention. However, due to lack of molecular biological basis of pharmacodynamics mechanism, it has not yet reached the standard of scientific treatment. The discovery of OPG/RANK/RANKL system has become a new breakthrough point in the prevention and treatment of bone metabolic diseases. The pathogenesis of deficiency of spleen and kidney - blood stasis - caused by phlegm arthralgia caused by blood stasis is closely related to the system. The effect of the final control of the system from the deficiency theory can be expressed through the axial micro-information. This article discussed the TCM syndrome differentiation of steroid-induced osteonecrosis of the femoral head and the relation of regulation of bone metabolism combined with the OPG/RANK/RANKL system, and provided the basis for prevention and treatment of this disease.

In recent years, due to the irregular and abused use of glucocorticoid in clinical treatment, the incidence of steroid induced avascular necrosis of femoral head (SANFH) is gradually increasing. TCM for the prevention and treatment of SANFH has received much attention from many scholars. However, due to the lack of the scientific explanation of molecular biology level for its pharmacodynamics mechanism, it is difficult to achieve the purpose of standardized treatment. The discovery of OPG/RANK/RANKL signaling pathway has opened up new shortcuts for the prevention and treatment of bone metabolic diseases. OPG/RANK/RANKL signaling pathway is associated with the pathogenesis of spleen deficiency and phlegm - blood stasis caused by phlegm-blood stasis due to paralysis of SANFH. The treatment efficacy based on the phlegm theory can eventually axial control of the system through the micro-information to express. This article discussed the relevance between the phlegm in the treatment of SANFH and molecular biology mechanism of OPG/RANK/RANKL signal regulation mechanism, and combined the system of bone metabolism regulation mechanism to discuss TCM differentiation of SANFH, with a purpose to provide references for clinical and further study.

Objective To observe the effects of Najia method of midday-midnight point selection for acute ischemic stroke (AIS) model rats onthe contents of NSE and S100B protein in serum. Methods SPF SD male rats were chosen to establish the models by middle cerebral artery bolt method. Rats were divided into blank group, sham-operation group, model group, channel-point group, and Najia method group by random number table method. Blank group, sham-operation group, and model group were in the absence of treatment, while the channel-point group received acupuncture treatment according to differentiation syndrome. Najia method group used Najia method of midday-midnight point selection to conduct acupuncture treatment once a day. Improvement of neural function and cerebral infarction volume were observed. The contents of NSE and S100B protein in serum were detected. Results Compared with model group, neurological function score, infarct volume and infarct volume percentage, and the contents of NSE and S100B protein in serum decreased in Najia method group and channel-point group (P<0.05, P<0.01). The effects of Najia group were generally better than the channel-point group. Conclusion Najia method of midday-midnight point selection can decrease the content of NSE and S100B protein in serum of AIS model rats, so as to achieve the effects of neuroprotection and treatment.

AIM: To investigate the mechanism of the AP-1 signal transduction pathway inhibited by JIP in nasopharyngeal carcinoma cells. METHODS: AP-1 activity was triggered by Dox-induced LMP1 expression in Tet-on-LMP1-HNE 2 cells (L7). The retention of phospho-JNK in the cytoplasm caused by JIP was examined with immunofluroscence assay. RESULTS: 24 h after transfection of L7 cells with the JIP expression plasmid, the translocation of activated JNK was inhibited, which resulted in the retention of phospho-JNK in the cytoplasm and down-regulation of the AP-1 activity. CONCLUSION: JIP down-regulates the activity of AP-1 through the inhibition of the translocation of JNK.
