OBJECTIVE: To compare the clinical efficacy of acupuncture with Neiguan (PC6)-to-Waiguan (TE5) and esmolol on hemodynamics during anesthesia induction and postoperative nausea and vomiting. METHODS: A total of 100 patients undergoing elective laparoscopic hernia repair or gynecological surgery under general anesthesia were randomly divided into an acupuncture group (50 cases, 3 cases were eliminated) and an esmolol group (50 cases, 2 cases were eliminated). In the acupuncture group, before anesthesia induction, patients were applied to acupuncture with Neiguan (PC6)-to-Waiguan (TE5), and the needles were retained for 15 min on the right side and 30 min on the left side. Patients in the esmolol group were intravenously injected with 20 mg esmolol hydrochloride injection 5 min before anesthesia induction. The systolic blood pressure (SBP) and heart rate (HR) of the two groups were recorded at 5 min after entering the operating room (T₀), before anesthesia induction (T₁), after anesthesia induction (T₂), before tracheal intubation (T₃) and 1 min after tracheal intubation (T₄). The visual analogue scale (VAS) scores of pain and the incidence of nausea and vomiting in the two groups were observed at the time of entering postanesthesia care unit (PACU) (T₅), leaving PACU (T₆), 6 h after operation (T₇) and 24 h after operation (T₈). The dosage of anesthesia-related drugs in the two groups was counted. RESULTS: The SBP and HR of the two groups at T₂, T₃ and T₄ were lower than those at T₁ (P<0.05). SBP and HR at T₃ in the acupuncture group were higher than those in the esmolol group (P<0.05). Compared with the esmolol group, in the acupuncture group, the VAS scores of pain at T₆ and T₇ were decreased (P<0.05), the incidence of nausea and vomiting at T₇ and T₈ and the nausea and vomiting visual analogue scale (NVAS) scores were decreased (P<0.05). Compared with the esmolol group, the dosage of propofol in the acupuncture group was decreased (P<0.05). CONCLUSION Acupuncture with Neiguan (PC6)-to-Waiguan (TE5) can relieve hemodynamic fluctuations during anesthesia induction, reduce postoperative pain and nausea and vomiting, and reduce the dosage of propofol. The curative effect is better than that of esmolol.

Objective To explore the effect of compound active tea of Lithocarpus litseifolius on uric acid levels and kidney function of mice with hyperuricemia nephropathy and to provide an experimental basis for the development of hyperuricemia nephropathy drugs and functional food.Methods A mouse model of hyperuricemia nephropathy was established by administering potassium oxazinate with adenine.Mice were randomly divided into common,model,positive drug(10 mg/(kg·d))and compound active tea of Lithocarpus litseifolius high-,middle-and low-dose groups(10 g/(kg ·d),3.33 g/(kg·d)and 1.11g/(kg·d),respectively).One hour after the last gavage,urine protein(UP)was measured by CBB method,urea nitrogen(UUN)was measured by urease method.Orbital blood pampling,blood was collected for uric acid(UA)analysis by enzyme ratio method,urea nitrogen(BUN)was measured by urease method.The serum contents of interleukin 6(IL-6)and tumor necrosis factor(TNF-α)were measured by ELISA.Take kidney tissue,levels of urate transporter 1(URAT1)and glucose transporter 9(GLUT9)were measured by quantitative fluorescence,kidney histopathological changes were observed by HE stainning.Results Compared with the control group,the model group's levels of UP,UUN,UA,BUN,IL-6,URAT1,ULUT9 and TNF-α were significantly increased(P＜0.01,P＜0.05),and the renal tissue structure was normal.Compared with the model group,the positive group's levels of UP,UUN,UA,BUN,IL-6 and TNF-α were significantly decreased(P＜0.01,P＜0.05),there was little glomerular atrophy or deformation in the kidneys,kidney tubular dilatation was occasionally seen,but there was no inflammatory cell infiltration.Compared with the model group,the high-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA,BUN,IL-6,URAT1,TNF-α and GLUT9 levels were significantly decreased(P＜0.01,P＜0.05).The middle-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA content,IL-6,URAT 1,GLUT9,BUN and TNF-αwere significantly decreased(P＜0.01,P＜0.05).The low-dose compound active tea of Lithocarpus litseifolius group's UP,UUN,UA,IL-6,URAT1,BUN,TNF-α and GLUT9 levels were significantly decreased(P＜0.01,P＜0.05).Conclusions Compound active tea of Lithocarpus litseifolius can reduce uric acid in mice with hyperuricemia nephropathy and has a certain protective effect on the kidneys.The mechanism may be related to the inhibition of uric acid reabsorption,and the specific mechanistic details should be further investigated.

Objective:To analyze the bone turnover markers in systemic lupus erythematosus (SLE) patients with different disease activity and the risk factors of osteoporosis.Methods:In this retrospective study, a total of 417 SLE inpatients were enrolled from the Department of Rheumatology and Immunology, the First Affiliated Hospital of Xi′an Jiaotong University, from March 2019 to June 2020. According to SLEDAI score, the patients were divided into 3 groups: 281 patients disease with inactive disease group; 99 patients with mild active disease group; and 37 patients with moderate/severe active disease. ANOVA test was used to compare the differences in serum bone turnover markers (PTH, NOST, VITDT, β-crossl, TP1NP, Ca and P) and bone density (Spine L 1~4 and left femur) among the three groups, and Tukey's method was used for the two groups comparison. Logistic regression analysis was used to investigate the risk factors of osteoporosis. Results:Serum VITDT, β-crossl and Ca levels were significantly different among the 3 groups ( F=11.66, P<0.001; F=7.22, P<0.001; F=29.38, P<0.001). Compared with patients in the inactive group, patients with both the mild disease group (VITDT: t=3.94, P<0.001; Ca: t=5.10, P<0.001) and the moderate/severe disease group (VITDT: t=3.33, P<0.001; Ca: t=7.19, P<0.001) had lower VITDT levels [(20.3±9.7) ng/ml vs. (15.9±9.3) ng/ml vs. (14.8±7.4) ng/ml] and serum Ca levels [(2.19±0.15)mmol/L vs. (2.09±0.21)mmol/L vs. (2.00±0.16)mmol/L]. Moreover, the moderate/severe disease group patients had much lower serum Ca levels ( t=2.36, P<0.05), compared with patients with the mild disease group. Compared with the patients with inactive group, both the mild activey group ( t=3.06, P<0.01) and the moderate/severe activie group ( t=2.99, P<0.01) patients had higher serum β-crossl levels [(419±316) pg/ml vs. (543±424) pg/ml vs. (586±343) pg/ml]. Compared with patients with the inactive disease group both patienes with the mild active group and the moderate/severe disease group patients had significantly decreased spine BMD ( t=2.75, P<0.01; t=2.71, P<0.01), Z-score ( t=5.65, P<0.001; t=4.70, P<0.001), T-score ( t=3.02, P<0.01; t=3.37, P<0.001), whereas, no difference was found between the mild disease group and moderate/severe disease group. Compared with the inactive group patients, both the mild active group and moderate/severe disease group patients had lower left femur BMD levels ( t=2.83, P<0.001; t=2.65, P<0.001) and T-score ( t=2.24, P<0.05; t=1.977, P<0.05) and no difference was found between the mild disease group and the moderate/severe disease group. Logistic regression analysis showed that age [ HR (95% CI)=1.080 (1.052, 1.109), P<0.001], BMI [ HR (95% CI)=0.801 (0.704, 0.911), P<0.001], SLEDAI score [ HR (95% CI)=1.047 (1.025, 1.076), P<0.05] and cumulative glucocorticoids dose [1.046 (1.006, 1.087), P<0.05] were associated with osteoporosis of SLE patients. Conclusion:Abnormal bone metabolism and decreased bone density are associated with SLE disease activity in SLE patients, especially in those with advanced age, low BMI and receiving high cumulative dose of glucocorticoids. Osteoporosis should be proactively prevented in the SLE patients.

Objective To investigate the correlation between Yes-associated protein(YAP)nuclear expression and tumor size with prognosis of patients with epithelial ovarian cancer(EOC)and to study the role of YAP in EOC.Methods 120 patients with EOC were selected as the experimental group,including 38 patients with early stage(Ⅰ+Ⅱ)EOC and 8 2 patients with advanced stage(Ⅲ+Ⅳ)EOC.3 0 normal ovarian tissues obtained from patients with uterine leiomyoma were enrolled as the control group.Immunohistochemical(IHC)assay was em-ployed to determine YAP expression and sub-location.The relationship between YAP expression and the pathologi-cal parameters of the 120 patients with EOC was analyzed,so as to the prognosis of these patients.EOC cells(C13K and OV2008)were cultured with varying initial cell volumes.Ki67 expression and cell proliferation were tested by immunofluorescence and cloning assay respectively.YAP expression at mRNA and protein levels were de-tected by q-PCR and Western blot respectively when the cell conference of EOC cells reached to low(60％)and high(90％)cell density.Results The YAP nuclear expression was significantly higher in the EOC group com-pared to the control group(P＜0.05).The average diameter of stage Ⅰ+Ⅱ EOC was larger than that of stage Ⅲ+Ⅳ EOC(P＜0.01).The high nuclear expression of YAP was positively associated with pathological grade,clinical stage and the level of Ca125＞1 000 IU/ml,while negatively correlated with tumor size(all P＜0.05).Survival analyses showed that smaller tumor size(＜10 cm)and higher YAP nuclear expression were negatively as-sociated with the 3-year overall survival rate of EOC patients(P＜0.01).C13K and OV2008 cells cultured in the low density group exhibited a high number of clone formation,high Ki67 and YAP expression(P＜0.01).The down-regulation of YAP expression could decrease the cell viability of EOC cells in the low-and high-density groups(P＜0.05).Conclusion Higher level of YAP nuclear expression and smaller tumour size are inversely associated with the clinical prognosis of patients with EOC.Inhibiting YAP nuclear expression leads to a decrease in the prolif-eration capacity of EOC cells.

Objective:To explore potential predictors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in early stage. Methods:The prospective multicenter study was conducted in Zhejiang, China from May 1 st, 2019 to January 31 st, 2020. A total of 1 428 patients with fever >48 hours to <120 hours were studied. Their clinical data and oral pharyngeal swab samples were collected; Mycoplasma pneumoniae DNA in pharyngeal swab specimens was detected. Patients with positive Mycoplasma pneumoniae DNA results underwent a series of tests, including chest X-ray, complete blood count, C-reactive protein, lactate dehydrogenase (LDH), and procalcitonin. According to the occurrence of RMPP, the patients were divided into two groups, RMPP group and general Mycoplasma pneumoniae pneumonia (GMPP) group. Measurement data between the 2 groups were compared using Mann-Whitney U test. Logistic regression analyses were used to examine the associations between clinical data and RMPP. Receiver operating characteristic (ROC) curves were used to analyse the power of the markers for predicting RMPP. Results:A total of 1 428 patients finished the study, with 801 boys and 627 girls, aged 4.3 (2.7, 6.3) years. Mycoplasma pneumoniae DNA was positive in 534 cases (37.4%), of whom 446 cases (83.5%) were diagnosed with Mycoplasma pneumoniae pneumonia, including 251 boys and 195 girls, aged 5.2 (3.3, 6.9) years. Macrolides-resistant variation was positive in 410 cases (91.9%). Fifty-five cases were with RMPP, 391 cases with GMPP. The peak body temperature before the first visit and LDH levels in RMPP patients were higher than that in GMPP patients (39.6 (39.1, 40.0) vs. 39.2 (38.9, 39.7) ℃, 333 (279, 392) vs. 311 (259, 359) U/L, both P<0.05). Logistic regression showed the prediction probability π=exp (-29.7+0.667×Peak body temperature (℃)+0.004×LDH (U/L))/(1+exp (-29.7+0.667×Peak body temperature (℃)+0.004 × LDH (U/L))), the cut-off value to predict RMPP was 0.12, with a consensus of probability forecast of 0.89, sensitivity of 0.89, and specificity of 0.67; and the area under ROC curve was 0.682 (95% CI 0.593-0.771, P<0.01). Conclusion:In MPP patients with fever over 48 to <120 hours, a prediction probability π of RMPP can be calculated based on the peak body temperature and LDH level before the first visit, which can facilitate early identification of RMPP.

Objective To explore association between childhood trauma,resilience and non-suicidal self-injury in adolescents.Methods One hundred and fifty-eight first-episode adolescent patients with mood disorders were selected and divided into NSSI group(n=94)and non-NSSI group(n=64)based on presence or absence of NSSI.The Hamilton depression scale(HAMD),Hamilton anxiety scale(HAMA),childhood trauma questionnaire(CTQ-SF)and Connor-Davidson resilience scale(CD-RISC)were used to evaluate the depression and anxiety symptoms,childhood trauma and resilience.Results There were more cases of younger age(16.17±1.67 vs.16.73±1.37),lower education level(30.9% vs.15.6% ),left behind experience(48.9% vs.29.7% ),school bullying(46.8% vs.25.0% ),suicide ideation(85.1% vs.37.5% )and history of attempted suicide(29.8% vs.6.3% )in the group with NSSI compared to those without NSSI.The HAMD score(27.99±5.94 vs.24.19±5.19),HAMA score(18.02±5.94 vs.15.45±4.99),CTQ total score(48.43±15.40 vs.41.97±9.75),emotional abuse score(12.77±6.06 vs.10.19±4.06),and emotional neglect score(11.40±5.34 vs.9.14±3.55)were higher in the group with NSSI,and the differences between the two groups were significant(P<0.05).The total scores of psychological resilience(39.83±10.27 vs.28.66±12.75),resilience(19.59±4.92 vs.12.28±6.47),strength(12.03±3.98 vs.9.99±4.67),and optimism(8.98±2.97 vs.6.47±3.73)in the group without NSSI were higher than those in the group with NSSI(P<0.05).Logistic regression analysis showed that left behind experience(OR=4.494,95% CI:1.192-16.940),school bullying(OR=5.983,95% CI:1.329-26.945),suicidal ideation(OR=13.225,95% CI:2.908-60.146),history of attempted suicide(OR=16.769,95% CI:1.845-152.379),HAMD(OR=1.264,95% CI:1.046-1.626),emotional abuse(OR=1.327,95% CI:1.093-1.612),and resilience(OR=0.468,95% CI:0.266-0.823)were significantly associated with adolescent mood disorders with NSSI(P<0.05).Conclusion Left behind experience,campus bullying,suicidal ideation and attempted suicide,emotional abuse,degree of depression,and psychological resilience may be associated with NSSI behavior in adolescents with mood disorders.

Objective To explore the influence of IL-6 secreted by cancer-associated fibroblasts(CAFs)on pro-moting the proliferation and invasion of ovarian cancer cells and the possible mechanisms.Methods CAFs and normal ovarian fibroblasts(NFs)were isolated and cultured respectively from epithelial ovarian cancer and normal ovarian epithelial tissues.Cell markers alpha-smooth muscle actin(α-SMA),E-cadherin were detected by West-ern blot and immunofluorescence.CAFs and normal ovarian fibroblasts(NFs)were collected and cultured,and their supernatants were used to establish an indirect co-culture system with ovarian cancer SKOV3 cells,including SKOV3 cells alone(SKOV3)group,SKOV3 combined with the supernatants of NFs(NFs)group and SKOV3 combined with the supernatants of CAFs(CAFs)group.Cell immunochemistry was used to detect the expression of alcohol dehydrogenase 1B(ADH1B)in SKOV3 cells co-cultured with the supernatant of CAFs or NFs.Before and after treatment with the methylation inhibitor 5-aza-2'-deoxycytidine(5-Aza-dC),methylation-specific PCR(MSP),Reverse transcription quantitative real-time PCR(RT-qPCR),enzyme-linked immunosorbent assay(ELISA),and Western blot were used to detect the mRNA level and methylation status of ADH1B,and the phos-phorylation level of signal transducers and activators of transcription 3(p-STAT3).The cell counting kit-8(CCK-8)method and Transwell assay were used to investigate the effects of the IL-6 inhibitor LMT-286 and recombinant human interleukin-6(rhIL-6)on cell proliferation and invasion.Results The protein levels of α-SMA was highly expressed,however,CAFs and NFs cells almost lacked the E-cadherin protein.Compared with the SKOV3 and NFs groups,CAFs group exhibited significantly downregulated mRNA and protein expression of ADH1B.After treatment with 5-Aza-dC,ADH1B methylation was partially reversed,and the mRNA and protein expression of ADH1B increased in all groups.The phosphorylation level of STAT3 proteins was significantly reduced in CAFs group,while there were no significant changes in SKOV3 and NFs groups.Intervention with LMT-286 and rhIL-6 only inhibited or promoted the proliferation and invasion of cells in CAFs group,while there were no significant changes in SKOV3 and NFs groups.Conclusion CAFs can enhance the methylation of ADH1B in ovarian cancer cells via IL-6/STAT3 pathway,and may promote the proliferation and invasion.

Objective To explore the effect of different treatment methods on prognosis in elderly patients with lower extremity arterial occlusive disease.Methods A total of 352 elderly patients with lower extremity arterial occlusive disease admitted in our hospital from May 2020 to May 2022 were enrolled,and according to their willingness and characteristics of lower extremity le-sions,they were divided into balloon dilation group(142 patients),stent implantation group(145 patients)and conservative treatment group(65 patients).All patients were followed up for 13-24 months.The incidences of major adverse cardiovascular events(MACE),including all-cause death,acute myocardial infarction,acute ischemic stroke,and major adverse lower limb events(MALE),including lower extremity pain at rest,ulcers or skin defects,gangrene,reocclusion,and amputation were observed and recorded.The clinical data and prognosis were compared and ana-lyzed of the three groups.Kaplan-Meier survival curves were drawn.Results The incidence of all-cause mortality was significantly lower in the stent implantation group than the conservative treatment group(9.7％vs 23.1％,P＜0.01).The incidence of MALE was obviously lower in the stent implantation group and the balloon dilatation group than the conservative treatment group(4.8％and 9.2％vs 24.6％,P＜0.01).Conclusion Endovascular therapy can reduce the risk of all-cause death and MALE occurrence in elderly patients with lower extremity arterial occlusive disease who are suitable for interventional therapy.

Metabolic-associated fatty liver disease (MAFLD), which is previously known as non-alcoholic fatty liver disease (NAFLD), represents a major health concern worldwide with limited therapy. Here, we provide evidence that ferroptosis, a novel form of regulated cell death characterized by iron-driven lipid peroxidation, was comprehensively activated in liver tissues from MAFLD patients. The canonical-GPX4 (cGPX4), which is the most important negative controller of ferroptosis, is downregulated at protein but not mRNA level. Interestingly, a non-canonical GPX4 transcript-variant is induced (inducible-GPX4, iGPX4) in MAFLD condition. The high fat-fructose/sucrose diet (HFFD) and methionine/choline-deficient diet (MCD)-induced MAFLD pathologies, including hepatocellular ballooning, steatohepatitis and fibrosis, were attenuated and aggravated, respectively, in cGPX4-and iGPX4-knockin mice. cGPX4 and iGPX4 isoforms also displayed opposing effects on oxidative stress and ferroptosis in hepatocytes. Knockdown of iGPX4 by siRNA alleviated lipid stress, ferroptosis and cell injury. Mechanistically, the triggered iGPX4 interacts with cGPX4 to facilitate the transformation of cGPX4 from enzymatic-active monomer to enzymatic-inactive oligomers upon lipid stress, and thus promotes ferroptosis. Co-immunoprecipitation and nano LC-MS/MS analyses confirmed the interaction between iGPX4 and cGPX4. Our results reveal a detrimental role of non-canonical GPX4 isoform in ferroptosis, and indicate selectively targeting iGPX4 may be a promising therapeutic strategy for MAFLD.
