Objective To evaluate the protective effect of human nucleus pulposus cell by Liraglutide(Lir)under high-glucose environment via inhibition of NOD-like receptor family,pyrin domain containing 3(NLRP3)inflammasome activation and its mechanism.Methods Human nucleus pulposus cell lines were cultured and the third-generation nucleus pulposus cells were randomly divided into control group(Con group),high glucose group(HG group),and Liraglutide interference group(Lir group),and cultured for 48 h.ELISA was used to detect interleukin IL-1β;flow cytometry was used to testreactive oxygen species(ROS),and Western blot was used to evaluate the protein expressions of NLRP3,Pro-caspase-1,and Caspase-1.Results Compared with Con group,IL-1β,ROS,NLRP3,Pro-caspase-1,Caspase-1 protein expression and cell apoptosis were increased in HG and Lir groups(P<0.05).Compared with HG group,IL-1β,ROS,NLRP3,Pro-caspase-1,Caspase-1 protein expression and cell apoptosis were significantly decreased in Lir group(P<0.05).Conclusion Liraglutide protects human NPCs by inhibiting the activation of NLRP3 inflammasome,reducing IL-1β secretion,and inhibiting cell apoptosis.

Objective To investigate the incidence and influencing factors of aggressive behavior in adolescent inpatients with mental disorders.Methods A total of 372 patients with mental disorders admitted to the Department of Child and Adolescent Psychiatry of the Second Affiliated Hospital of Xinxiang Medical University from January to December 2022 were selected as research subjects.The occurrence of aggressive behavior and its influencing factors were analyzed.Results Among the 372 patients,38(10.2％)cases had aggressive behavior during hospitalization.Univariate and multivariate logistic regression results showed that the history of aggressive behavior,only child,and high irritation factor scores were the risk factors of aggressive behavior in hospitalized adolescents with mental disorders(P＜0.05).Mild,outgoing,insecure and isolated personalities before the onset were protective factors of aggressive behavior in hospitalized adolescents with mental disorders(P＜0.05).Conclusion Adolescent inpatients with mental disorders are likely to have aggressive behavior.Those who have aggressive behavior before,are the only child in their family and get a high score of irritant factors need more attention.Corresponding nursing interventions should be taken in time through nursing assessment to reduce the occurrence of aggressive behavior.

Objective:To investigate the efficacy and safety of atorvastatin combined with indobufen in the treatment of elderly patients with diabetic kidney disease (DKD) complicated with large atheromatous ischemic stroke (LAA-IS) during convalescence.Methods:The clinical data of 102 elderly patients with DKD complicated with LAA-IS during convalescence from September 2018 to April 2022 in Baoding Second Central Hospital were retrospectively analyzed. Among them, 51 patients were treated with atorvastatin combined with indobufen (observation group), 51 patients were treated with atorvastatin combined with aspirin (control group), and both groups were treated continuously for 6 months. The prethrombotic state indexes, neurological function and quality of daily life, carotid artery ultrasound indexes, renal fibrosis indexes before treatment and after treatment were compared between two group. The prethrombotic state indexes included arachidonic acid (AA) and adenosine diphosphate (ADP) induction platelet aggregation rate, fibrinogen (FIB), protein C; the National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological function, and the modified Barthel index (MBI) was used to evaluate the quality of daily life; carotid artery ultrasound indexes included carotid artery intima-media thickness (IMT) and maximum plaque area; the renal fibrosis indexes included transforming growth factor-β 1 (TGF-β 1), matrix metalloproteinase-9 (MMP-9), hyaluronic acid and platelet derived growth factor-BB (PDGF-BB). The adverse reactions were recorded. Results:There were no statistical differences in the all indexes before treatment between two groups ( P>0.05). In two groups, compared before treatment, the AA induction platelet aggregation rate, ADP induction platelet aggregation rate, FIB, NIHSS score, IMT and maximum plaque area after treatment were significantly lower, the protein C and MBI score were significantly higher, and there were statistical differences ( P<0.01); but there were no statistical differences after treatment between two groups ( P>0.05). The TGF-β 1, MMP-9, hyaluronic acid and PDGF-BB after treatment in two groups were significantly lower than before treatment, and the indexes in observation group were significantly lower than those in control group: (39.46 ± 6.89) μg/L vs. (45.04 ± 8.20) μg/L, (278.46 ± 49.39) μg/L vs. (327.30 ± 57.28) μg/L, (102.37 ± 20.62) μg/L vs. (116.84 ± 24.97) μg/L vs. (25.26 ± 4.45) μg/L vs. (28.13 ± 5.08) μg/L, with statistically significant differences( P<0.01). The incidence of adverse reactions in observation group was significantly lower than that in control group: 7.84% (4/51) vs. 23.53% (12/51), and there was statistical difference ( P<0.05). Conclusions:Compared with atorvastatin combined with aspirin, atorvastatin combined with indobufen in elderly patients with DKD complicated with LAA-IS during convalescence has the same effect in improving the related indicators of prethrombotic state, reducing neurological function deficit, improving the ability of daily living, and reversing carotid atherosclerosis. However, atorvastatin combined with indobufen can further protect renal function with higher safety.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Objective By comparing with arthroscopic rotator cuff repair alone,to explore the efficacy and difference of leukocyte poor platelet-rich plasma(LP-PRP)and leukocyte rich platelet-rich plasma(LR-PRP)in arthroscopic rotator cuff repair.Methods Sixty patients with total rotator cuff tear accompanied by arthroscopic rotator cuff repair admitted to the Affiliated Hospital of North China University of Science and Technology from October 2021 to September 2022 were included and randomly divided into control group(n=20),LP-PRP group(n=20)and LR-PRP group(n=20).The control group only received arthroscopic rotator cuff repair.The LP-PRP group was injected with leukocyte poor platelet-rich plasma(LP-PRP)into the sutured torn tendon after the same operation,and the LR-PRP group was injected with leukocyte rich platelet-rich plasma(LR-PRP)into the sutured torn tendon after the same operation.The postoperative rehabilitation training plan of the three groups was the same,and the postoperative follow-up and evaluation were conducted for 1 year.It included pain score(VAS score),shoulder joint function score(CMS,UCLA,ASES score),retear rate and related complications.Results All patients were followed up.(1)VAS score:Compared with the LR-PRP group and the control group,the results were statistically significant only at 1,3 and 6 weeks after surgery(P<0.05);There was no statistical significance between the LR-PRP group and the control group at 1 week,3 weeks,6 weeks,3 months,6 months and 12 months after surgery(P>0.05).(2)CMS,UCLA and ASES scores:There were no significant differences between the LP-PRP group and the LR-PRP group at 3 months,6 months and 12 months after surgery(P>0.05);Compared with LP-PRP group and LR-PRP group,there were significant differences in each follow-up time point of control group(P<0.05).(3)Retear rate:In the LP-PRP group,there was 1 retear in the LR-PRP group(tear rate 5%),and 3 in the control group(tear rate 15%).There was no statistically significant difference between the three groups(P>0.05).(4)There were no postoperative complications in 60 patients.Conclusions Compared with arthroscopic rotator cuff repair alone,although the application of LP-PRP and LR-PRP could not reduce the rate of retear,it could significantly improve the shoulder joint function of patients,and LP-PRP could significantly reduce the pain of patients with rotator cuff injury in the early postoperative period(within 6 weeks),with no postoperative complications,and the short-term clinical results of patients were satisfactory.

Objective:To evaluate the effect of different doses of compound sodium chloride injection combined with norepinephrine on prevention of hypotension after lumbar anesthesia in the patients undergoing caesarean section.Methods:A total of 150 patients with a singleton fetus, aged 18-45 yr, at ≥37 weeks of gestation, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, with height ≥150 cm, weighing ≤100 kg, with body mass index < 40 kg/m 2, scheduled for elective caesarean section under lumbar anesthesia, were divided into 3 groups ( n=50 each) by the random number table method: compound sodium chloride injection 4, 8 and 12 ml·kg -1·h -1 groups (group A, group B, group C). Compound sodium chloride injection 4 ml/kg was intravenously injected for liquid preload before lumbar anesthesia, and 0.5% hyperbaric bupivacaine 12.5 mg was injected to the subarachnoid space for lumbar anesthesia. Norepinephrine was intravenously injected at a dose of 6 μg immediately after intrathecal injection, followed by an infusion of 0.05 μg·kg -1·min -1, and infusion was stopped at 5 min after delivery. Compound sodium chloride injection was intravenously infused simultaneously at a rate of 4, 8 and 12 ml·kg -1·h -1 in A, B and C groups, respectively. The maximum diameter of inferior vena cava (IVCmax) and the minimum diameter of inferior vena cava (IVCmin) were measured by ultrasound, and inferior vena cava collapse index (IVC-CI) was calculated at 1 min before fluid preload (T 1), immediately after fluid preload (T 2), at 5 min after anesthesia (T 3), at 5 min after fetal delivery (T 4) and immediately before leaving the operating room (T 5). The incidence of intraoperative adverse events (hypotension, severe hypotension, bradycardia, hypertension, nausea, and vomiting) and neonatal outcomes (umbilical artery blood gas index and Apgar score at 1 and 5 min after birth) were recorded. Results:Compared with group A, IVCmin was significantly increased and IVC-CI was decreased at T 5 in group B, and IVCmin and IVCmax were significantly increased and IVC-CI was decreased at T 5 in group C ( P<0.05). There was no significant difference in IVCmax, IVCmin and IVC-CI at each time point between group B and group C ( P>0.05). There was no significant difference in the incidence of hypotension, severe hypotension, bradycardia, hypertension, nausea and vomiting among the three groups ( P>0.05). There was no significant difference in the results of blood gas analysis of the umbilical artery and Apgar score at each time point after birth among the three groups ( P>0.05). Conclusions:Compound sodium chloride injection 4, 8 and 12 ml·kg -1·h -1 combined with norepinephrine can effectively prevent the occurrence of hypotension after lumbar anesthesia in the patients undergoing caesarean section without increasing maternal and infant adverse events, and the effect of 8 and 12 ml·kg -1·h -1 for volume supplementation is better than that of 4 ml·kg -1·h -1.

Objective:To evaluate the outcome of laser coagulation under fetoscope for placental chorioangioma (CA).Methods:The clinical data of three pregnant women with giant CA treated by laser coagulation under fetoscope in Peking University Third Hospital from January 2018 to December 2020 were analyzed retrospectively. Relevant articles up to September 2022 were retrieved from Wanfang Database, China National Knowledge Infrastructure and PubMed, and the clinical data of all patients were retrospectively summarized. Indications and intervention effects of fetoscopic laser therapy were analyzed. Descriptive statistics was used to describe the data.Results:Thirteen patients were involved in this study including 10 cases retrieved from the databases. The average age of the pregnant women was (30.3±6.2) years old. There were 12 cases of single pregnancy and one case of twin pregnancy (monochorionic diamnionic twin pregnancy). Except for cases for which data were not available in the literatures, at the diagnosis of CA, the average gestational age was (19.9±4.5) weeks ( n=7) and the average maximum diameter of the mass was (6.1±4.1) cm ( n=6). The patients underwent fetoscopic laser therapy at an average gestational age of (25.0±2.0) weeks ( n=13) with the average maximum tumor diameter of (7.6±2.8) cm ( n=9). After treatment, the amniotic fluid volume of three cases decreased to normal. In one case, the amniotic fluid volume decreased but was still above the upper limit of the normal range. Moreover, the maximum tumor diameter decreased in four cases; the peak systolic velocity of the fetal middle cerebral artery decreased to normal in one case; fetal heart function became normal in two cases and fetal edema was relieved in one case. Among the three patients treated in our hospital, the blood supply of CA disappeared after treatment. Intrauterine fetal death occurred in two cases. The other 11 patients gave birth to live babies at the gestational age of (36.6±3.8) weeks with five through cesarean section (5/11), five through vaginal delivery (4/11) and two not reported. The birth weight of the neonates was (2 712±1 023) g and all of them survived. The gender of five neonates were reported and all were females, two of them were monochorionic diamnionic twins. No abnormality was found in the three neonates delivered in our hospital during a six-month follow-up. No abnormality was reported in the other neonates during ten days to six months of follow-up. Conclusions:Fetoscopic laser coagulation may help reduce the size of CA, decrease complications and improve pregnancy outcomes.

Objective To explore the application effect of high-functioning group therapy model in female patients with depression.Methods A total of 80 female patients with depression who were hospitalized in the Department of Psychiatry,the Second Affiliated Hospital of Xinxiang Medical University from April 2021 to April 2022 were selected as the research sub-jects.According to the treatment methods,the patients were divided into the observation group and the control group,with 40 patients in each group.The patients in the two groups were treated with routine anti-depressant drugs based on their condition;the patients in the control group received routine nursing interventions based on their condition;the patients in the observation group received high-function group therapy intervention on the basis of the control group;the patients in the two groups were in-tervened for 1 month.Before and one month after the intervention,the levels of depression and anxiety of patients in the two groups were evaluated by the Hamilton depression scale(HAMD)and the Hamilton anxiety scale(HAMA);the quality of life of patients in the two groups was evaluated by the World Health Organization's quality of life scale(WHOQOL-BREF),while the interpersonal relationships of patients in the two groups were evaluated by the interpersonal relationships comprehensive diagnostic scale.Results Before intervention,there was no statistically significant difference in the scores of HAMA,HAMD,WHOQOL-BREF and interpersonal relationship comprehensive diagnostic scale of patients between the two groups(P＞0.05).The HAMA and HAMD scores of patients in the two groups after one month of intervention were significantly lower than those before intervention(P＜0.05);after one month of intervention,the HAMA and HAMD scores of patients in the observa-tion group were significantly lower than those in the control group(P＜0.05).The WHOQOL-BREF scores in the social,psychological,physiological and environmental domains of patients after one month of intervention were significantly higher than those before intervention in the two groups(P＜0.05);after one month of intervention,the WHOQOL-BREF scores in the social,psychological,physiological and environmental domains of patients in the observation group were significantly higher than those in the control group(P＜0.05).The scores of interpersonal interaction,conversation,social interaction and hetero-sexual interaction and total scores of interpersonal relationship comprehensive diagnosis scale of patients one month of interven-tion were significantly lower than those before intervention in the two groups after(P＜0.05);after one month of intervention,the scores of interpersonal interaction,conversation,social interaction and heterosexual interaction and total scores of interper-sonal relationship comprehensive diagnosis scale of patients in the observation group were significantly lower than those in the control group(P＜0.05).Conclusion Compared to conventional nursing interventions,the high-functioning group therapy model can significantly reduce the depression and anxiety of female depression patients,improve interpersonal communication skills and their quality of life.

Objective:To establish an Epstein-Barr virus-transformed peripheral blood B cell line (BCL), and explore its phenotypic characteristics, the ability to secrete antibodies and cytokines, and the ability to present hepatitis B virus (HBV) antigen peptide.Methods:Peripheral blood mononuclear cells (PBMCs) were isolated from patients with HBV infection. Epstein-Barr virus supernatant was incubated to construct BCL. The expression of CD19, CD138, CD38, CD27 and the production levels of IFN - γ, IL-10, IL-6 were detected by flow cytometry. BCL loaded with HBV antigen peptide was incubated with in vitro-expanded autologous T cells. Intracellular staining was used to detect the level of interferon-gamma produced by T cells.Results:Compared with untransformed peripheral blood B cells, BCL had high expression levels of CD138, CD38 and CD27, and the difference was statistically significant ( P < 0.05), while the level of IL-6 production was decreased, and the difference was statistically significant ( P < 0.01). BCL loaded with HBV antigen peptide had significantly enhanced the production of interferon-gamma by in vitro-expanded autologous T cells, and the difference was statistically significant ( P < 0.01). Conclusion:BCL highly expresses CD138, CD38 and CD27, but its ability to produce IL-6 decreases. BCL can improve the immune response efficiency of HBV-specific T cells to HBV antigen peptide, and serve as a new tool for hepatitis B immune research.

Objective　We investigated the correlation of MMP-2，MMP-14 with the vulnerability of carotid plaque. Our study was to explore the related factors which influence the stability of the plaques. Methods　Carotid plaques were collected from patients undergoing CEA in the Department of Neurosurgery of the First people’s Hospital of Lianyungang. 55 patients were recruited between January 2018 and June 2019.All of the plaques were divided into 23 stable carotid plaques and 32 vulnerable carotid plaques by imaging and histological analysis. Immunohistochemistry was used toloca lize the expression level of MMP-2 and MMP-14 in stable and vulnerable plaques. Results　Density analysis revealed that the immunohistochemical staining of MMP-2 and MMP-14 were more intense among samples from vulnerable group than those from stable group. MMP-2 and MMP-14 staining was positive in ulcer plaque and the atheromatous lesions. Conclusion　The expression of MMP-2 and MMP-14 were associated with plaque vulnerability of human carotid plaques，which is an important factor affecting the stability of plaques.
