ObjectiveTo observe the effects of modified Chaihu Shugansan on the calmodulin-dependent protein kinase Ⅱ（CaMKⅡ）/cAMP-response element binding protein （CREB） signaling pathway in the hippocampus and heart tissue of a rat model with myocardial ischemia and depression and explore the mechanism by which this formula prevents and treats coronary heart disease combined with depression. MethodsThe model of myocardial ischemia combined with depression was established by high-fat diet， intraperitoneal injection of isoproterenol （ISO）， and chronic unpredictable mild stress （CUMS）. A total of 108 SD male rats were randomly divided into normal group， model group， high （23.4 g·kg^-1）， medium （11.7 g·kg^-1）， and low （5.85 g·kg^-1） dose groups of modified Chaihu Shugansan， CaMKⅡ inhibitor （KN93） group， and KN93 + high， medium， and low dose groups of modified Chaihu Shugansan， with 12 rats in each group. From the first day of modeling to the end of modeling， drugs were administered once a day. In the seventh and eighth weeks， the KN93 group and the KN93 + high， medium， and low dose groups of modified Chaihu Shugansan were intraperitoneally injected with KN93 three times weekly. At the end of the eighth week， behavioral tests including sucrose preference， open field， and elevated plus maze were conducted. Electrocardiogram （ECG） lead Ⅱ changes were observed in each group of rats， and hematoxylin-eosin （HE） staining was performed to observe changes in heart tissue. Serum levels of triglycerides （TG）， total cholesterol （TC）， high-density lipoprotein （HDL）， low-density lipoprotein （LDL）， and lactate dehydrogenase （LDH） were measured by using an enzyme-labeled instrument. Creatine kinase （CK） and creatine kinase-MB （CK-MB） were detected by ultraviolet spectrophotometry， while serum monocyte chemoattractant protein-1 （MCP-1） was measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect mRNA expression of CaMKⅡ and CREB in hippocampal and heart tissue， and Western blot was performed to assess protein expression of CaMKⅡ， phosphorylated （p）-CaMKⅡ， CREB， and p-CREB. ResultsCompared to the normal group， the model group showed significant reductions in sucrose preference rate， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）. The ECG showed ST-segment elevation， and HE staining showed serious degeneration of myocardial fibers， disordered arrangement， and infiltration of a large number of inflammatory cells. In addition， serum TC and LDL levels increased （P<0.01）， and HDL level decreased （P<0.01）. CK， CK-MB， LDH， and MCP-1 levels significantly increased （P<0.05， P<0.01）. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB decreased in the hippocampal tissue （P<0.05， P<0.01）， but those increased in the heart tissue （P<0.01）. Compared to the model group， the high， medium， and low dose groups of modified Chaihu Shugansan showed improvements in these abnormalities. The KN93 group had reduced sucrose preference， total activity distance in the open field， number of entries into the center area of the open field， and percentage of entries into the open arms of the elevated plus maze （P<0.01）， as well as decreased serum CK， CK-MB， LDH， and MCP-1 levels （P<0.05， P<0.01）. KN93 also reduced ST-segment elevation， alleviated the degeneration degree of myocardial fibrosis， and lowered inflammatory cell infiltration. The mRNA expression of CaMKⅡ and CREB and the protein expression of p-CaMKⅡ and p-CREB in both the hippocampal and heart tissue were reduced （P<0.05， P<0.01）. The KN93 + high， medium， and low dose groups of modified Chaihu Shugansan showed further improvements in these abnormalities compared to the KN93 group. ConclusionThe modified Chaihu Shugansan exerts antidepressant and myocardial protective effects in rats with myocardial ischemia and depression， possibly related to bidirectional regulation of the CaMKⅡ/CREB signaling pathway， with the high-dose modified Chaihu Shugansan showing the best effects.

Objective To analyze the short-term clinical efficacy and influencing factors of ustekinumab monoclonal antibody(UST)in the treatment of Crohn′s disease(CD).Methods Retrospective cohort study was used to collect the clinical data of CD patients treated with UST in the 10th People′s Hospital affiliated to Tongji University from December 2020 to October 2022.The main analysis is the short-term clinical efficacy and influencing factors of UST treatment for CD at weeks 8 and 16,And analyze the endoscopic response rate of some patients.Results A total of 91 CD patients who first used UST were included.The 8-week clinical response rate of UST treat-ment for CD was 61.5%,and the clinical response rate was 45%;The clinical response rate at 16 weeks was 71.4%,and the clinical response rate was 54.9%.56 cases underwent endoscopic re-examination in our hospital,and the endoscopic response rate at 16 weeks was 41.1%.Univariate analysis showed that fistula(including anal fistula,personal history of anal fistula,and intestinal skin fistula)is associated with clinical remission in Crohn′s disease patients at 8/16 weeks.Further multivariate COX regression analysis showed that the presence of a history of anal fistula surgery was an independent protective factor affecting clinical remission in CD patients treated with UST at 8 weeks(HR = 0.04,95%CI:0.00～0.38;P = 0.005)and 16 weeks(HR = 0.04,95%CI:0.01～0.34;P = 0.003)compared to those without fistula;Narrow lesions are an independent risk factor for 16 week clinical remission in CD patients compared to non-narrow and non-penetrating lesions(HR = 1.75,95%CI:1.08～2.84;P = 0.023).No patients were found to have stopped medication due to serious adverse reactions.Conclusions UST can improve the clinical remission and response of CD patients at 8/16 weeks,and has good short-term clinical efficacy.CD patients with a personal history of anal fistula are recommended to use UST monoclonal antibodies,while patients with stenotic lesions should be cautious in using UST monoclonal antibodies.Whether the patient has undergone surgical treatment in the past,as well as whether UST has been used on the first or non-first line,has no significant impact on clinical remission.

Objective: To explore growth and intelligence development of low birth weight infants (LBWI) at 24 and 36 months of age, so as to provide reference for early monitoring and intervention of the development of LBWI. Methods: A total of 100 LBWI born and managed in Hefei Maternal and Child Health Care Institution were selected from 2012 October 1 to 2015 December 30, and 99 normal birth weight infants (NBWI) under child health management in the same sitinstitution were selected as controls. According a prospective cohort study method, and based on the establishment of a cohort and monitoring of childhood growth and development, a unified method was used to longitudinally follow up and observe the physical fitness of two groups of infants at the determined time points. The development of LBWI and NBWI at 24 and 36 months of age was surveyed using the Gesell Development Scale. Results: Weight, length and head circumference of LBWI children at the age of 15-36 months were significantly lower than those of NBWI children ( P <0.05). In addition, 117 children (43.98%) completed the full assessment of intelligent development scale, including 62 LBWI and 55 NBWI. The scores of Gesell in NBWI group was higher than that in LBWI group at 24 and 36 months of age, including adaptability, gross motor, fine metor skills, language and personal social functions ( t =-4.17, -3.82, -3.21 , -3.03, -2.61; -4.23, -3.16, -3.07, -3.13, -3.99, P <0.05). Multivariate linear regression analysis found that birth weight was positively correlated with adaptability, gross motor, fine motor skills, language functions at 24 and 36 months of age and personal social function at 36 months of age ( β =0.004, 0.010; 0.003, 0.008; 0.003, 0.007; 0.004, 0.009; 0.011, P ＜0.05). Conclusion The growth and development of LBWI children are significantly delayed compared to NBWI children. The scores of LBWI children are lower than those of NBWI children in all functional areas. Weight is the main factor affecting children s intellectual development. Early monitoring and intervention of low birth weight infants should be carried out to avoid or mitigate adverse consequences.

Objective:To identify the relationship between exposure to mobile phones and other electronic products and the ability development in children.Methods:Retrospective study.A total of 218 children aged 0.5-6.0 years presented to the Department of Health Care, Beijing Children′s Hospital, Capital Medical University form September 2019 to June 2020 for developmental examination were included.Those with nervous system, mental system diseases, endocrine system diseases and premature children were excluded.Their development was evaluated and the information about exposure to mobiles phones and other electronic products were collected. Chi- square test and Fisher′ s exact probability method were used to analyze the relationship between the exposure to mobile phones and other electronic products and the ability development in children.The influencing factors of children′s development in various fields were analyzed by the binary Logistic regression. Results:Abnormal fine movements of children aged 0.5-0.9 years were related to the latest time every night of exposure ( P<0.05). Abnormalities of adaptability, language and social self-care in children aged 1.0-2.9 years and abnormality of language in children aged 3.0-5.9 years were correlated with the number of hours of daily exposure (all P<0.05). Abnormalities of language and social self-care in children aged 1.0-2.9 years and abnormalities of adaptability, language and social self-care in children aged 3.0-5.9 years were correlated with the purposes of exposure (all P<0.05). Binary Logistic regression analysis indicated that the children′s gross motor was affected by the number of hours of daily exposure ( OR=1.868, P<0.05). The children′s fine motor movements were affected by mother′s educational level and the latest time every night of exposure ( OR=1.722, 2.355, all P<0.05). The children′s adaptability was affected by mother′s educational level, child caregivers, the number of hours of daily exposure and the latest time every night of exposure ( OR=1.711, 2.866, 1.895, 1.650, all P<0.05). The children′s speech was affected by the number of hours of daily exposure, the latest time every night of exposure, and the purposes of exposure (telephone or video phone, early education or study)( OR=2.348, 1.806, 0.328/0.350, all P<0.05). The children′s social interaction and self-care delay were affected by mother′s educational level, the number of hours of daily exposure and the purposes of exposure (telephone or video phone, early education or study)( OR=1.647, 2.678, 0.307/0.363, all P<0.05). Conclusions:The adverse effects of exposure to mobile phones and other electronic products on children should be well concerned.The exposure time of developing young children should be strictly controlled to prevent the adverse effects on the nervous system and development in children.For children who were already affected, relevant habits and behaviors should be timely corrected to avoid irreversible damages.

Objective:To improve the understanding of the diagnosis and treatment of early T-cell precursor acute lymphoblastic leukemia (ETP-ALL).Methods:The clinical data of a patient with ETP-ALL who was misdiagnosed as peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) admitted to the Second Hospital of Lanzhou University in October 2020 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient who presented "inguinal lymphadenopathy" as the first symptom underwent lymph node biopsy and pathological examination at local hospital, and he was diagnosed as PTCL-NOS according to the consultation of another 2 hospitals. After 2 courses of chemotherapy (CHOPE regimen, GLD regimen, unknown specific medication and dosage), the therapeutic efficacy was poor. For further diagnosis and treatment, this patient came to Lanzhou University Second Hospital. Flow cytometry found blast cells in the bone marrow, and then other related examinations were completed, he was finally diagnosed as ETP-ALL. The chemotherapy regimens of Hyper-CVAD and EA were alternatively used, progressive disease (PD) occurred after 3 courses of treatment, and chidamide was added in the 4th and 5th courses of treatment, the disease still progressed, and the patient died after follow-up. The disease course of the patient was about 12 months.Conclusions:ETP-ALL has unique immunophenotypic characteristics. ETP-ALL patients have a low remission rate after conventional induction therapy, high recurrence rate and poor prognosis. Currently, there is no effective standard treatment regimen, and allogeneic hematopoietic stem cell transplantation or timely addition of new drugs may improve the prognosis.

Objective:To observe the incidence of syncope in patients with acute and critical cardiovascular diseases and to explore the risk factors of death.Methods:925 cases of acute heart failure, acute myocardial infarction, pulmonary embolism, arrhythmia and aortic dissection rupture who participated in Prospective, Multi-CenterRegistered Research Project for Chinese Syncope Patients from March 2018 to March 2020, admitted to the department of emergency of Nanyang Second General Hospital were selected as the research objects. The incidence and mortality of syncope were recorded, and the patients were divided into syncope group and non-syncope group according to whether they were accompanied by syncope or not. The incidence of syncope in male and female patients with different cardiovascular critical diseases, the age and mortality of cardiovascular critical patients with syncope or not were analyzed and compared. Multivariate Logistic regression analysis was used to analyze the risk factors of death, and receiver operating characteristic curve (ROC curve) was drawn to evaluate the predictive value of risk factors on the prognosis of patients.Results:The incidence of syncope in 5 kinds of cardiovascular critical patients from high to low was: acute myocardial infarction 3.03% (28/925), arrhythmia 2.70% (25/925), pulmonary embolism 1.51% (14/925), aortic dissection rupture 1.41% (13/925), acute heart failure 0.65% (6/925), with statistically significant differences ( χ2 = 10.765, P = 0.010). There was no significant difference in the incidence of syncope between male and female patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia and acute heart failure. The age of patients with aortic dissection rupture, acute myocardial infarction and arrhythmia in syncope group were significantly higher than those in non-syncope group [aortic dissection rupture (years old): 66.29±15.64 vs. 57.63±14.23, acute myocardial infarction (years old): 69.55±15.13 vs. 62.10±15.75, arrhythmia (years old): 70.48±14.93 vs. 60.29±16.31, all P < 0.05]. The mortality of patients with pulmonary embolism, aortic dissection rupture, acute myocardial infarction, arrhythmia, acute heart failure in syncope group were significantly higher than those in non-syncope group [pulmonary embolism: 5.81% (5/86) vs. 0.95% (8/839), aortic dissection rupture: 4.65% (4/86) vs. 0.60% (5/839), acute myocardial infarction: 4.65% (4/86) vs. 1.19% (10/839), arrhythmia: 2.33% (2/86) vs. 0.95% (8/839), acute heart failure: 2.33% (2/86) vs. 0.60% (5/839), all P < 0.05]. Multivariate Logistic regression analysis showed that age [odds ratio ( OR) = 2.158, 95% confidence interval (95% CI) was 0.921-4.785, P = 0.000], pulmonary embolism ( OR = 15.391, 95% CI was 8.904-27.314, P = 0.001), aortic dissection rupture ( OR = 13.079, 95% CI was 6.237-25.509, P = 0.000), acute myocardial infarction ( OR = 18.826, 95% CI was 10.420-32.921, P = 0.000), syncope ( OR = 4.940, 95% CI was 1.764-9.287, P = 0.000) were risk factors for the prognosis of patients with acute and critical cardiovascular diseases. ROC curve analysis showed that syncope had a certain predictive value for 28-day prognosis of patients [the area under the ROC curve (AUC) = 0.760, P = 0.000], when the cut-off value was 4.12, the sensitivity was 88.51%, the specificity was 78.05%, the positive predictive value was 81.31%, and the negative predictive value was 84.27%. Conclusions:Syncope is an independent risk factor of death in patients with acute and critical cardiovascular diseases. For patients with syncope as the chief complaint, we should quickly identify the types of acute and critical diseases and assess the risk of sudden death.

Objective:To evaluate the effectiveness of syncope unit in improving the diagnosis efficiency and treatment prognosis of patients with suspected syncope.Methods:The standardized syncope unit was established in the Affiliated Nanyang Second General Hospital of Xinxiang Medical College in 2018. Patients with suspected syncope attending from November 2018 to April 2019 (before the establishment of syncope unit) and from May to October 2019 (after the establishment of syncope unit) were enrolled in the study. There were 109 cases attending before the establishment of syncope unit (control group) and 126 cases attending after establishment (syncope unit group). The positive rate of examination, the treatment and its cost before and after the establishment of syncope unit were compared. After one year, the follow-up rate, recurrence rate, rehospitalization rate, treatment satisfaction and quality of life of patients were documented and compared between two periods.Results:The positive rates of tilt table test [61.90%), Holter monitoring [64.29%(81/126)], exercise stress test [7.14%(9/126)] invasive electrophysiology [40.48%(51/126)], cardiac imaging [9.52%(12/126)] and 24-h blood pressure monitoring [55.56%(70/126)] in syncope unit group were significantly higher than those in control group [44.95%(49/109), 36.70%(40/109), 5.50%(6/109), 10.09%(11/109), 2.75%(3/109) and 40.37%(44/109); χ2=19.28, 23.11, 6.93, 28.18, 15.85 and 11.61,respectively; all P<0.01]. The diagnostic rate of etiology in syncope unit group was significantly higher than that in control group [87.30%(110/126) vs. 77.06%(84/109), χ2=21.70, P<0.01].The time from onset to cardiac assessment and hospitalization time in syncope unit group were significantly shorter than those in control group[(3.68±1.93)h vs. (7.31±2.64)h;(6.17±1.52)d vs. (10.83±2.09)d]. The hospitalization rate [3.17%(4/126) vs. 8.26%(8/109)], hospital mortality [0.79%(1/126) vs. 2.75%(3/109)] and treatment cost [(4.91±1.14) thousands Yuan vs. (7.05±2.53) thousands Yuan] in syncope unit group were significantly lower than those in control group ( t=14.49, P<0.01; t=8.62, P=0.02;χ2=15.83, P<0.01;χ2=10.03, P=0.01; t=6.17, P=0.03).The outpatient follow-up rate [82.54%(104/126)] and treatment satisfaction rate [91.35%(95/104)] in syncope unit group were significantly higher than those in control group [61.47%(67/109) and 64.18%(43/67)]; and the recurrence rate [14.42%(15/104)] and rehospitalization rate [7.69%(8/104)] in syncope unit group were significantly lower than those in control group [40.30%(27/67) and 23.88%(16/67)](χ2=17.30, 20.37, 18.56, 15.08,all P<0.01). The scores of psychological status, physiological status, environmental status, social relations and overall quality of life in contral group were significantly lower than those in syncope unit group (43.62±12.84 vs. 59.13±13.95,43.10±11.31 vs. 5.86±12.09,52.35±12.76 vs. 63.58±13.05,54.87±12.08 vs. 67.91±14.23,58.42±11.87 vs. 69.28±13.51; t=7.74, P=0.03; t=7.50, P=0.03; t=8.66, P=0.02; t=9.77, P=0.01; t=8.46, P=0.02, respectively). Conclusion:The establishment of standardized syncope unit is helpful to improve the diagnosis efficiency and the prognosis of patients with suspected syncope, and also reduce the cost of diagnosis and treatment.

Objective To explore the effect Tiaoli-Qixue decoction on bleeding and coagulation during perioperative period of total hip arthroplasty (THA).Methods A total of 180 THA patients who met the inclusion criteria were randomly divided into three groups with 60 cases in each group.All patients underwent routine anti-infection treatment after unilateral THA through lateral hip approach.The patients took the Tiaoli-Qixue decoction 3 days before THA in the treatment group.The patients in the Xuesaitong control group received intravenous Xuesaitong on the day of operation and rivaroxaban tablets were administered orally on the day of operation in the westem medicine control group.The continuous medication was administered until 7 days after operation in three groups.The amount of hemorrhage and drainage after operation were recorded and the total amount of dominant hemorrhage was calculated.The Degao M4 semi-automatic hemagglutination instrument was used to detect plasma D-dimer level and observe thrombosis.Harris scale was used before and after operation to calculate the excellent and good rates of Harris score.Results The total amount of dominant hemorrhage (376.67 ± 61.44 ml vs.400.08 ± 61.16 ml,413.33 ± 53.76 ml,F=5.963),intraoperative hemorrhage (165.50 ± 15.67 ml vs.174.75 ± 14.68 ml,175.42 ± 11.13 ml,F=9.452) and postoperative drainage (211.17 ± 58.12 ml vs.225.33 ± 56.93 ml,237.92 ± 54.28 ml,F=3.370) in the treatment group of traditional Chinese medicine were significanlty less than those in the Xuesaitong control group and the Western medicine control group (P＜0.01 or P＜0.05).On the 7th day after operation,there were 6 cases of thrombosis in the treatment group of traditional Chinese medicine,4 cases in the Xuesaitong control group and 4 cases in the Western medicine control group.There was no significant difference between the three groups (x2=0.667,P=0.881).Six months after operation,the excellent and good rate of that the treatment group of traditional Chinese medicine was 45.0％ (27/60),which of the the Xuesaitong control group was 11.7％ (7/60),and which of the the Western medicine control group was 13.3％ (8/60).There was significant difference among the three groups.Conclusions The Tiaoli-Qixue decoction bleeding and coagulation can reduce the amount of dominant bleeding during perioperative period in patients with THA,and effectively prevent and treat deep venous thrombosis of lower limbs after THA.

BACKGROUND: The choice of suitable bone graft substitute is vital for spinal fusion treatment, which can solve some limitations caused by autogenous bone graft and other materials. OBJECTIVE: To investigate properties of different bone graft fusion materials, and to explore their application in dog spinal fusion of lumbar vertebral body. METHODS: Forty-five Chinese rural dogs were enrol ed to prepare lumbar interbody fusion models, and then were randomized into three groups transplanted with autogenous ilium, recombinant human bone morphogenetic protein-2 composite or al ograft ilium, respectively. Afterwards, effects of different materials in the lumbar interbody fusion were analyzed. RESULTS AND CONCLUSION: The fusion rate of the composite group was significantly higher than those of the other groups (P < 0.05). Oswestry dysfunction index of the composite group was significantly lower than those of the other groups after surgery (P < 0.05). Hematoxylin-eosin staining showed that dogs achieved complete bony fusion, continuous bone trabecula gradual y formed, and there was no gap between the transplanted bone and the bone surface in the composite group compared with the other groups at 12 weeks after surgery. These results demonstrate that recombinant human bone morphogenetic protein-2 composites can significantly promote the spinal fusion superior to autologous and al ogeneic bone grafts.

Objective:To comparatively analyze the efficacy of S-1 plus cisplatin as first-line chemotherapy between advanced AFP posi-tive and AFP negative gastric cancer. Methods:A total of 89 eligible patients with advanced gastric cancer from January 2010 to June 2013 were enrolled in this retrospective study. The cases were divided into AFP positive group (n=18) and AFP negative group (n=71) based on serum AFP level before treatment. Both groups received S-1 plus cisplatin as first-line treatment. Results:Significant differ-ences were observed in remission rate (66.7% versus 32.4%, P=0.028) and radical surgical resection rate (44.5% versus 18.3%, P=0.029) after chemotherapy between AFP positive group and AFP negative group. In the two groups, neither progression-free survival nor overall survival (OS) showed any significance (P>0.05) in patients without surgery after chemotherapy. However, the disease-free survival of the two groups with radical surgical resection after chemotherapy was significantly different (median:27.0 months versus 15.6 months, P=0.034). The OS of the AFP positive group was evidently longer than that of the AFP negative group (median:16.0 months versus 11.0 months, P=0.005). Conclusion:As first-line chemotherapy, S-1 plus cisplatin was more effective for the advanced AFP positive gastric cancer and prolonged overall survival.
