Schizophrenia has various obstacles in cognition， thinking， emotion， behavior and other aspects； it belongs to the category of “madness” in traditional Chinese medicine （TCM）. Once schizophrenia occurs， multiple factors are often intertwined， and a single therapy is difficult to be effective. At present， TCM compounds and active ingredients have significant effects in the clinical treatment of schizophrenia， which is an important direction for the development of new drugs for schizophrenia. This article summarizes the molecular mechanism of TCM compounds and active ingredients in the treatment of schizophrenia. It is found that Wendan decoction and Yudian decoction can inhibit the apoptosis of hippocampal cells by activating BDNF/TrKB/CREB signaling pathway； quercetin and icariin can promote neural development and regeneration by activating NMDA/ERK signaling pathway； Wendan decoction and icariin can maintain neural cell homeostasis by activating PI3K/AKT signaling pathway； Bushen zhuangyang capsule can enhance learning and memory abilities by activating CaMKⅡ signaling pathway； formulas such as Huatan huoxue tongzhi formula can enhance intercellular information transmission by inhibiting PKC signaling pathway； α-humulene and others can restore nerve cell function by inhibiting NRG1/ErbB4 signaling pathway. TCM compounds and active ingredients can improve schizophrenia by intervening in the above-mentioned signaling pathways.

Human physiological indicators have become an important standard for assessing health in modern society.Traditional detection methods often require a separate laboratory,complex operation process and long detection time,so it is urgent to develop portable,fast and accurate on-site detection technologies for bioanalysis.Point-of-care testing(POCT),which differs from traditional laboratory testing,can realize the rapid in situ detection of biomarkers without the complicated analytical process of the laboratory.Smartphones,which are an essential tool in our daily life,not only have independent operating systems and built-in storage functions,but also have high-definition cameras,which have great application potential in POCT visualization.The combination of various biosensing technologies and smartphones has developed into a new direction in the field of POCT.This review mainly introduced the research progress of smartphone-based visual biosensors in POCT in recent years,including colorimetric sensors,fluorescence sensors,chemiluminescence sensors and electrochemiluminescence sensors.Finally,the problems faced by smart-phone-based visual biosensors in the application of POCT were summarized,and their future development was prospected.

Objective To evaluate the safety and efficacy of CT-guided percutaneous transhepatic gallbladder drainage(PTGBD)in treatment of high-risk acute cholecystitis(AC)patients.Methods CT-guided PTGBD was performed in 29 patients with high-risk AC.The therapeutic results were evaluated by comparing the preoperation and postoperation clinical manifestations and laboratory results.Results The implantation of PTGBD catheter was successfully accomplished with single procedure in all patients.Complica-tions occurred in 2 cases,including abdominal pain in 1 case and a small amount of gallbladder bleeding in 1 case,and the incidence of complications was 6.9%.Compared with preoperation,the pain number rating scale(NRS)score,temperature(T),white blood cell count(WBC),C-reactive protein(CRP),total bilirubin(TBIL),alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were significantly decreased 3 days after PTGBD(P<0.001).Except for 1 case of choledocholithiasis with continuous abdominal pain after PTGBD,the postoperation symptoms of the other patients were significantly relieved.Followed up for 3 months,2 cases of calculous AC recurred after PTGBD,and the recurrence rate of cholecystitis was 25.0%.Conclusion For high-risk AC,the CT-guided PTGBD is a safe and effective treatment method,and it can remarkably relieve the clinical symptoms.Patients with calculous AC have higher risk of recurrence and might benefit from definitive cholecystectomy.

Hepatectomy is the most effective method for the treatment of liver cancer. Asso-ciating liver partition and portal vein ligation for staged hepatectomy (ALPPS) provides resectable opportunities for patients with unresectable or borderline resectable liver cancer. Traditional ALPPS procedures involve a short interval between two stages of the surgery, leading to a higher incidence of perioperative complications and mortality. The authors present a case of two-stage hepatectomy. Initially, laparoscopic ligation of the right hepatic artery and portal vein was performed. To prevent tumor progression after the first stage of surgery, combined immunotherapy and targeted therapy were administered. Three months later, a successful right hemihepatectomy was performed. Postoperative histopathological examination revealed hepatocellular carcinoma with extensive tumor necrosis. A 15-month follow-up showed no tumor recurrence. This indicated that two-stage hepatectomy including simultaneous ligation of the hepatic artery and portal vein, combined with two-stage hepatectomy plus immunotherapy and targeted therapy, showed considerable promise for borderline resectable liver cancer.

Objective:To investigate the factors influencing the right heart dysfunction in myloproliferative neoplasm (MPN) patients with BCR::ABL fusion gene-negative.Methods:A retrospective case-control study was conducted. A total of 130 MPN patients with BCR::ABL fusion gene-negative admitted to the Second People's Hospital of Lianyungang from January 2020 to December 2022 were selected as the study objects. The general data, laboratory indexes and cardiac function parameters were collected. All patients were divided into the control group (non-right heart function injury, 96 cases) and the observation group (right heart function injury, 34 cases) according to whether there was right heart dysfunction judged by ultrasonic cardiogram. Multivariate logistic regression analysis was used to analyze the independent influencing factors of right heart dysfunction in MPN patients with BCR:: ABL fusion gene-negative. Taking right heart dysfunction judged by ultrasonic cardiogram as the gold standard, the receiver operating characteristic (ROC) curve was drawn to predict right heart dysfunction according to independent influencing factors, and the diagnostic efficacy of the factors was analyzed.Results:The median age was 57 years old (range 19-76 years); among the 130 patients, 62 cases were male and 68 cases were female. There were 69 cases of primary thrombocytosis, 35 cases of polycythemia vera and 26 cases of primary myelofibrosis. The proportions of patients with age > 60 years old, hypertension, embolism history, pulmonary hypertension in the observation group were higher than those in the control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in the composition of patients with gender, body mass index > 28 kg/m2, smoking, drinking, diabetes, hyperlipidemia and different pathological types between the two groups (all P > 0.05). The white blood cell count, neutrophil count, basophil count, monocyte count, red blood cell count, hematocrit (Hct), CD34+ cell count and platelet count in the observation group were higher than those in the control group, and the differences were statistically significant (all P < 0.05). There were no statistically significant differences in lymphocyte count, eosinophilic count, triglyceride, total cholesterol, high density lipoprotein cholesterol, low density lipoprotein cholesterol and high sensitive C-reactive protein levels between the two groups (all P > 0.05). The cardiac ejection time in the observation group was shorter than that in the control group, but the transverse diameter of right atrium, anteroposterior diameter of right ventricle, anterior wall thickness of right ventricle, isovolumic systole time, isovolumic diastole time and right ventricular Tei index in the observation group were all higher than those in the control group, and the differences were statistically significant (all P < 0.001). Multivariate logistic regression analysis showed that age > 60 years (OR = 1.520, 95% CI: 1.250-1.692, P = 0.002), embolism history (OR = 1.765, 95% CI: 1.302-2.020, P = 0.001), pulmonary arterial hypertension (OR = 1.555, 95% CI: 1.303-1.702, P = 0.001), elevated Hct (OR = 1.900, 95% CI: 1.587-2.269, P = 0.002), the increased density of CD34+ cell (OR = 1.400, 95% CI: 1.158-1.630, P = 0.001), and increased Tei index of right ventricle (OR = 2.269, 95% CI: 1.700-3.568, P = 0.001) were independent risk factors of right heart dysfunction in MPN patients with BCR::ABL fusion gene-negative. ROC curve analysis showed that the area under the curve of age > 60 years old, embolism history, pulmonary arterial hypertension, Hct, the density of CD34+ cell, and Tei index of right ventricle, in predicting right heart dysfunction in MPN patients with BCR-ABL fusion gene-negative was 0.780 (95% CI: 0.690-0.925), 0.657 (95% CI: 0.533-0.740), 0.728 (95% CI: 0.660-0.813), 0.619 (95% CI: 0.510-0.708), 0.777 (95% CI: 0.720-0.809), 0.822 (95% CI: 0.749-0.886), respectively. The area under the curve of the 6 combined items was 0.930 (95% CI: 0.850-0.987). The sensitivity and specificity were 89.69% and 96.38% respectively when the optimum critical value was reached.Conclusions:Age > 60 years old, embolism history, pulmonary arterial hypertension, elevated Hct, the increased density of CD34+ cell and increased Tei index of right ventricle are independent risk factors of right heart dysfunction in MPN patients with BCR::ABL fusion gene-negative.

Objective:To explore the effect of nursing intervention based on the health action process approach (HAPA) theory on follow-up compliance and blood glucose management of patients with diabetes retinopathy (DR) .Methods:From October 2022 to May 2023, 102 DR patients who visited the Diabetes Fundus Clinic of Shanxi Eye Hospital were selected by convenience sampling as participants. A total of 51 patients who visited from October 2022 to January 2023 were selected as control group, and 51 patients who visited from February to May 2023 were selected as observation group. Control group received routine nursing, while observation group received nursing intervention based on HAPA theory on this basis. The follow-up compliance, Chinese version of the Compliance with Annual Diabetic Eye Exams Survey (CADEES-C) score, fasting blood glucose (FBG), 2-hour postprandial blood glucose (2hPG) and glycosylated hemoglobin (HbA1c) were compared between the two groups.Results:The compliance of DR patients in observation group after six months of follow-up was higher than that in control group, and the difference was statistically significant ( P<0.05). After six months, the CADEES-C dimension scores and total score of DR patients in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05). FBG and 2hPG of DR patients in observation group were lower than those in control group after three and six months, and the differences were statistically significant ( P<0.05). After six months of intervention, there was no statistically significant difference in HbA1c between observation group and control group ( P>0.05) . Conclusions:Nursing interventions based on HAPA theory can effectively improve the follow-up compliance of DR patients, enhance their health beliefs during follow-up, and improve their blood glucose.

Aim To investigate the effects of Radix Angelica Sinensis and Radix Hedysari ultrafiltration(RAS-RH)on oxidative stress and inflammatory injury of human umbilical vein endothelial cells(HUVECs)induced by ionizing radiation.Methods The model of HUVECs damage induced by 6 Gy X-rays was estab-lished.HUVECs were treated with different concentra-tions of RAS-RH(100,200,400 μg·L-1).The proliferative activity of HUVECs was detected by CCK-8 method,the structural changes of mitochondria were observed by transmission electron microscope,the level of ROS was detected by DCFH-DA probe,the change of intracellular mitochondrial membrane potential was detected by JC-1 kit,and the apoptosis and cycle were detected by flow cytometry.The contents of IL-6 and TNF-α in cells were detected by ELISA.The activities of MDA,CAT,SOD and GSH-PX were detected by biochemical kit.The gene expression levels of Nrf2,HO-1,NF-κB,eNOS and IL-6 were detected by qRT-PCR,and the expression levels of Nrf2,HO-1,eNOS,NF-κB,p-NF-κB and IL-6 protein were detected by Western blot.Results Compared with the model group,RAS-RH could increase the activity of HUVECs induced by ionizing radiation,decrease the rate of ap-optosis,decrease the level of intracellular ROS,re-duce the injury of intracellular mitochondria,increase the level of mitochondrial membrane potential,promote the expression of Nrf2,HO-1 and eNOS,and inhibit the expression of NF-κB and IL-6.Conclusions RAS-RH has anti-radiation,antioxidant and anti-in-flammatory effects,which may reduce the oxidative stress and inflammatory damage of HUVECs induced by ionizing radiation by activating the activity of Nrf2/HO-1 signal pathway,thus promoting the activity of cell proliferation.

Objective:To investigate the therapeutic effect and safety of pomadomide combined with cyclophosphamide and dexamethasone (PCD) in the treatment of relapsed/refractory multiple myeloma (MM).Methods:The clinical data of 20 relapsed/refractory MM patients receiving PCD regimen in the Second People's Hospital of Lianyungang Affiliated to Bengbu Medical College from March 2021 to June 2022 were retrospectively analyzed; and 29 relapsed/refractory MM patients receiving other regimens including DECP (dexamethasone+etoposide+cyclophosphamide+cisplatin, 13 cases) and VCD (bortezomib+ cyclophosphamide+ dexamethasone, 16 cases) during the same period were treated as the control group. The efficacy and adverse effects of both groups were compared after 4 cycles of treatment.Results:After 4 cycles of treatment, the overall response rate (ORR) and the clinical benefit rate (CBR) of 20 cases in PCD group was 70.0% (14/20) and 85.0% (17/20), respectively; among 20 cases, there were 5 cases of complete response (CR), 4 cases of very good partial remission (VGPR), 5 cases of partial remission (PR), 3 cases of minimal remission (MR), 2 cases of stable disease (SD), 1 case of the progression of the disease (PD). ORR and CBR of 29 cases in the control group was 41.4% (12/29) and 65.5% (19/29), respectively; among 29 cases, there were 2 cases of CR, 3 cases of VGPR, 7 cases of PR, 7 cases of MR, 5 cases of SD, 5 cases of PD. There was a statistically significant difference in ORR of both group ( χ2 = 3.89, P = 0.048), while the difference in CBR of both group was not statistically significant ( χ2 = 2.30, P = 0.129). There were 2 patients with renal impairment achieving CR in PCD group and 1 patient with renal impairment achieving CR in the control group ( P = 0.152); 1 genetically high-risk patient achieved CR in PCD group and none of patients in the control group achieved CR, and the difference was statistically significant ( P>0.05). The common hematological adverse effects of two groups were anemia, neutropenia, thrombocytopenia; the common non-hematological adverse effects were malaise, infection and fatigue, and the differences were statistically significant (all P>0.05). The incidence of grade 3-4 infection was 25.0% (5/20) in PCD group and the disease was under the control after anti-infective therapy, and the incidence of grade 3-4 infection was 24.1% (7/29) in the control group; and the difference was not statistically significant ( P > 0.05). Conclusions:PCD regimen has good clinical efficacy and safety in treatment of relapsed/refractory MM.

Objective:To investigate the inhibitory effect of phloretin on inflammation and oxidative stress in interleukin (IL)-1β induced orbital fibroblasts (OFs) from Graves orbitopathy (GO) patients and its mechanism.Methods:The orbital fat and connective tissue from 6 eyes of 6 patients diagnosed as inactive GO who underwent orbital decompression in Henan Eye Hospital from January 2019 to December 2020 were collected.Primary OFs were isolated and passaged by explant culture and were identified by cell immunofluorescence assay.OFs were divided into control group, IL-1β induced group, and groups of various phloretin concentrations (25, 50, 75, 100 and 200 μmol/L). The viability of OFs after 24- and 48-hour treatment of the various phloretin concentrations was determined by cell counting kit-8 (CCK-8). OFs were induced by IL-1β to simulate an inflammatory environment of GO in vitro.Intracellular reactive oxygen species (ROS) levels of the normal control group, IL-1β induced group, 50 μmol/L phloretin group and 100 μmol/L phloretin group were detected by fluorescent probe (H 2DCF-DA). The concentrations of pro-inflammatory cytokines IL-6, IL-8 and monocyte chemoattractant protein-1 (MCP-1) in cell culture supernatant of the normal control group, IL-1β induced group and phloretin treated groups (25, 50, 75, and 100 μmol/L) were examined by enzyme-linked immunosorbent assay (ELISA). The expressions of heme oxygenase-1 (HO-1), nuclear factor erythroid 2-related factor (Nrf2) proteins, as well as P38, extracelluar regulated protein kinase (ERK) and c-Jun N-terminal kinase (JNK) proteins as well as their phosphorylated proteins in the MAPK signal pathway of the normal control group, IL-1β induced group and 100 μmol/L phloretin group, were detected by Western blot.The purpose and methods of the study were explained to the patients and their family members.Written informed consent was obtained.The study protocol was approved by the Ethics Committee of Henan Provincial People's Hospital (No.HNEECKY-2020[07]). Results:For cultured OFs, the mesenchymal origin was confirmed by positive expression of vimentin and fibroblasts were identified by negative expression of desmin, S-100 and cytokeratin-18.CCK-8 showed that there was no significant difference in absorbance value after 24- and 48-hour treatment between 25 μmol/L, 50 μmol/L, 75 μmol/L and 100 μmol/L phloretin groups and control group (all at P>0.05). The ROS levels of 50 μmol/L and 100 μmol/L phloretin groups were 21.95±1.71 and 10.01±1.03, respectively, which were significantly lower than 39.27±4.01 of IL-1β induced group (both at P<0.01). ELISA showed that IL-6 concentrations in 25 μmol/L, 50 μmol/L, 75 μmol/L and 100 μmol/L phloretin groups were (4 544.25±572.98), (1 000.25±133.96), (724.25±98.63), (519.50±118.02)pg/ml, respectively, which were all significantly lower than (7 581.75±565.93)pg/ml in IL-1β induced group (all at P<0.01). IL-8 concentrations in 50 μmol/L, 75 μmol/L and 100 μmol/L phloretin groups were (3 679.50±676.76), (2 143.75±616.20), (1 174.75±284.18)pg/ml, respectively, which were all significantly lower than (8 411.00±939.67)pg/ml in IL-1β induced group (all at P<0.01). The concentrations of MCP-1 in 50 μmol/L, 75 μmol/L and 100 μmol/L phloretin groups were (3 783.25±610.24), (1 565.75±457.89), (745.75±227.01)pg/ml, respectively, which were all significantly lower than (5 533.00±602.87)pg/ml in IL-1β induced group (all at P<0.01). The relative expression levels of HO-1 and Nrf2 were significantly higher and the relative expression levels of p-P38, p-ERK, and p-JNK were significantly lower in 100 μmol/L phloretin group than IL-1β induced group (all at P<0.01). Conclusions:Phloretin reduces the oxidative stress level of IL-1β induced OFs from GO patients and inhibits the production of pro-inflammatory cytokines.The mechanism is related to the activation of Nrf2/HO-1 and the inhibition of the MAPK signal pathway.
