OBJECTIVE To investigate the efficacy and safety of ropivacaine combined with oxycodone for the analgesia of iliac fascia nerve block in patients undergoing hip replacement. METHODS Sixty-six patients who underwent hip replacement at the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture from October 2023 to April 2024 were selected and randomly divided into observation group and control group， with 33 cases in each group. Before induction of anesthesia， ultrasound-guided iliac fascial nerve block was performed. Patients in the observation group were treated with 0.33% ropivacaine+0.1 mg/kg oxycodone injection mixture 30 mL， and patients in the control group were treated with 0.33% ropivacaine injection 30 mL. The time of first postoperative rescue analgesia， 24 h postoperative analgesic drug consumption， sensory block and motor block effective and maintenance time， satisfaction degree， numerical rating scale （NRS） pain score， Ramsay sedation score， muscle strength score， heart rate （HR）， mean arterial pressure （MAP）， oxygen saturation（SpO2）， sleep score， anxiety score， and the occurrence of adverse reactions in the two groups were all recorded. RESULTS Compared with the control group， the first rescue analgesia time after operation was significantly prolonged in the observation group， and 24 h postoperative analgesic drug consumption after operation decreased； the effective time of sensory block was significantly shortened， and the maintenance time of sensory block was significantly prolonged， and the satisfaction score was higher； the NRS pain score after iliac fascia nerve block was lower， HR and MAP were lower， and the anxiety score and sleep score 24 and 48 h after operation were lower （P＜0.05）. In terms of safety， patients in both groups had adverse reactions after operation， such as hypertension， nausea， vomiting， and dizziness， but there was no significant difference in the incidence of adverse reactions between the two groups （P＞0.05）. CONCLUSIONS Oxycodone combined with ropivacaine shows good efficacy and safety for iliac fascial nerve block analgesia in patients undergoing hip replacement， can significantly prolong the analgesic time of ropivacaine， reduce postoperative analgesic drug consumption， improve the sleep quality of patients， and promote the rapid recovery of patients.

Objective To investigate the value of ¹⁸F-FDG PET/CT metabolic parameters in the prognostic assessment of nasopharyngeal cancer patients. Methods The clinical data and PET/CT metabolic parameters of 185 nasopharyngeal cancer patients were retrospectively analyzed. The collected parameters were SUV_max, MTV, TLG, total metabolic tumor volume (TMTV) and whole-body total lesion glycolysis (WTLG). The ROC curve was used to determine the optimal cut-off values of PET/CT metabolic parameters. Univariate and multivariate Cox regression models were used to screen the independent prognostic factors. Kaplan–Meier curves were used to analyze the survival differences. Results The results of univariate Cox regression analysis showed that age, pathologic type, WTLG, TMTV, MTV, and TLG were closely associated with OS and PFS; and SUV_max was associated with PFS (P<0.05). Multivariate Cox regression analysis results showed that age, TMTV, and WTLG were the independent prognostic factors for OS and PFS (P<0.05). The combination of WTLG with T/N staging (AUC=0.781 and 0.781) and TMTV with T/N staging (AUC=0.800 and 0.790) yielded greater predictive accuracy than that of WTLG and TMTV alone (AUC=0.724 and 0.719) or T/N staging (AUC=0.593 and 0.575). Conclusion TMTV and WTLG are important prognostic predictors of nasopharyngeal carcinoma. TLG and MTV of primary lesions are prognostic factors for patients’ PFS and OS. SUV_max has limited prognostic value. Systemic metabolic indexes (TMTV and WTLG), when combined with T/N staging, can optimize prognostic stratification.

The liver plays an important regulatory role in maintaining the dynamic balance of coagulation and anticoagulation in the body. Such dynamic balance is fragile in patients with liver cirrhosis， and the risk of bleeding can be increased due to reductions in coagulation factors and platelet count and excessive fibrinolysis； meanwhile， thrombus can be formed due to the increases in von Willebrand factor and coagulation factor Ⅷ， the reductions in anticoagulant protein C and anticoagulant protein S， the increase in thrombin-generating potential， and alterations in antifibrinolytic components. This article reviews the mechanisms of coagulation disorder in liver cirrhosis， so as to help clinicians with the prevention and treatment of bleeding or thrombotic disorders in patients with liver cirrhosis.

Objective:To investigate the clinical efficacy of dopamine hydrazine combined with carlobidopa controlled-release tablets in the treatment of Parkinson's disease and its effect on inflammatory reaction, serum homocysteine and YKL-40 levels in patients with Parkinson's disease.Methods:A case-control study was conducted to retrospectively analyze the clinical data of 230 patients with Parkinson's disease who received treatment at Xianyang Hospital of Yan 'an University from January 2020 to December 2022. According to the different treatment methods, these patients were divided into a dopamine hydrazine (treatment with dopamine hydrazine, n = 113) and a combination group (treatment with dopamine hydrazine and carlobidopa controlled-release tablets, n = 117). All patients were treated for 6 weeks. Inflammatory reactions, serum homocysteine levels, and serum YKL-40 levels post-treatment were compared with pre-treatment levels. Clinical efficacy and the incidence of adverse reactions were evaluated between the two groups. Results:After 6 weeks of treatment, the levels of tumor necrosis factor α, interleukin-1β, interleukin-6, and high-sensitivity C-reactive protein in the combination group were (9.76 ± 1.57) ng/L, (27.02 ± 3.41) ng/L, (10.29 ± 1.89) ng/L, and (6.62 ± 0.99) mg/L, respectively, which were significantly lower than those in the dopamine hydrazine group [(12.34 ± 1.97) ng/L, (30.84 ± 4.73) ng/L, (13.83 ± 2.18) ng/L, (8.77 ± 1.55) mg/L, t = -10.98, -7.04, -13.16, -12.58, all P < 0.05]. The serum levels of homocysteine and YKL-40 in the combination group were (19.08 ± 5.70) μmol/L and (3.33 ± 0.97) g/L, respectively, which were significantly lower than those in the dopamine hydrazine group [(22.54 ± 5.62) μmol/L, (4.03 ± 1.23) g/L, t = -4.63, -4.81, both P < 0.05]. The total response rate in the combination group was 94.02% (110/117), which was significantly higher than 78.76% (89/113) in the dopamine hydrazine group (χ2 = 11.47, P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:The use of dopamine hydrazine combined with carbidopa controlled-release tablets for the treatment of Parkinson's disease reduces inflammatory reactions, decreases serum homocysteine and YKL-40 levels, enhances clinical efficacy, and does not increase the incidence of adverse reactions.

Objective:To explore the economic applicability and safetyof the novel uterovaginal pubic comb suspension(UPCS)surgery with Mersilene tape in the treatment of pelvic organ prolapse(POP).Methods:A ret-rospective analysis was conducted on the clinical data of patients who underwent UPCS surgery due to POP from January 1st,2021 to February 28,2023.They were divided to the UPCS surgery with Mersilene tape group(group A)and suspension surgery with Y-shaped mesh group(group B)respectively.The POP-Q indication points,sus-pension surgery duration,intraoperative bleeding volume,material expense,postoperative catheter retention time,anal exhaust time and hospitalization duration were recorded for both groupbefore and after surgery.Evaluate the severity of POP related symptoms in patients before and after surgery using the pelvic Floor Distress Invento-ry-short Form 20(PFDI-20)and Pelvic Organ Prolapsed/Urinary Incontinence Sexual Questionnaire-12(PISQ-12),and follow up and observe the patients and analyze the complications.Results:A total of 17 POP patients were included in the study.There were 12 patients in group A while 5 patients in group B.The suspension material expense of group A was considerably lower than that of group B(P＜0.05).There was no significant difference between the two groups in preoperative PFDI-20 score,preoperative PISQ-12 score,UPCS surgery duration,intr-aoperative bleeding volume,postoperative urinary catheter retention time,postoperative anal exhaust time and hospitalization duration.All patients showed stable vital signs during the surgery and no severe complications were reported.Compared with the preoperative status,the positions of the Aa,Ba,and C indicatorpoint in group A and group B were all increased significantly(P＜0.05).The PFDl-20 and PISQ-12 scores of the two groups at the last follow-up after surgery showed significant improvement compared to those before surgery(P＜0.05).No signifi-cant difference was found in the PFDI-20 and PISQ-12 scores between the two groups after surgery(P＞0.05).There were no significant differences in the postoperative complications between the two groups(P＞0.05).Con-clusions:Compared with suspension surgery with Y-shaped mesh,UPCS surgery with Mersilene tape is safe and effective in the treatment of POP.The UPCS surgery with Mersilene tape showed better cost-effectiveness in the treatment of POP,and the surgical steps are relatively simple.Therefore,UPCS surgery with Mersilene tape was worthy of promotion in clinical practice.

Objective:To investigate the safety and feasibility of Ivor-Lewis procedure under uniportal video-assisted thoracoscopy(VATS) for esophageal cancer and Siewert type I esophago-gastric junction carcinoma.Methods:The patients with middle-lower segment esophageal cancer or Siewert type I esophago-gastric junction carcinoma received minimally invasive esophagectomy between October 2020 and June 2021, and the clinical data was collected and analyzed.Results:26 patients received Ivor-Lewis procedure underwent uniportal VATS, while 45 patients underwent McKeown surgery under multiport VATS. The average operation time of patients in the two groups were(265±110)min and (235±94)min, and the average intraoperative blood loss were(80±57)ml and(105±60)ml. The mean number of lymph nodes removed in the surgery were (19.3±2.9) and 18.6±2.7 respectively in two groups, and the mean length of hospital stay was(7.5±3.5)days and(8.3±2.7)days. The incidence of perioperative complications were not significantly different in two groups. The VAS score of patients received Ivor-Lewis procedure underwent uniportal VATS was lower than that of patients received McKeown surgery in ostoperative day 1, day 3, day 7 and 1 month. The difference was statistically significant in two groups( P<0.05). Conclusion:The Ivor-Lewis procedure under uniportal VATS for esophageal cancer and Siewert type I esophago-gastric junction carcinoma has the advantage of less postoperative pain, and the procedure is feasible in clinical practice.

Alcoholic liver disease(ALD)is the most frequent liver disease worldwide,resulting in severe harm to personal health and posing a serious burden to public health.Based on the reported antioxidant and anti-inflammatory capacities of scutellarin(SCU),this study investigated its protective role in male BALB/c mice with acute alcoholic liver injury after oral administration(10,25,and 50 mg/kg).The results indicated that SCU could lessen serum alanine aminotransferase(ALT)and aspartate aminotransferase(AST)levels and improve the histopathological changes in acute alcoholic liver;it reduced alcohol-induced malondialdehyde(MDA)content and increased glutathione peroxidase(GSH-Px),catalase(CAT),and superoxide dismutase(SOD)activity.Furthermore,SCU decreased tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and IL-1β messenger RNA(mRNA)expression levels,weakened inducible nitric oxide synthase(iNOS)activity,and inhibited nucleotide-binding oligomerization domain(NOD)-like receptor protein 3(NLRP3)inflammasome activation.Mechanistically,SCU suppressed cytochrome P450 family 2 subfamily E member 1(CYP2E1)upregulation triggered by alcohol,increased the expression of oxidative stress-related nuclear factor erythroid 2-related factor 2(Nrf2)and heme oxygenase-1(HO-1)pathways,and suppressed the inflammation-related degradation of inhibitor of nuclear factor-κB(NF-κB)-α(IκBα)as well as activation of NF-κB by mediating the protein kinase B(AKT)and p38 mitogen-activated protein kinase(MAPK)pathways.These findings demonstrate that SCU protects against acute alcoholic liver injury via inhibiting oxidative stress by regulating the Nrf2/HO-1 pathway and suppressing inflammation by regulating the AKT,p38 MAPK/NF-κB pathways.

Objective:To investigate the knowledge, attitude and practice status of ophthalmic nurses on prevention and control of intraocular infection in grade Ⅲ class A hospitals.Methods:A self-made questionnaire was used to investigate the knowledge, attitude and practice of 236 nurses on prevention and control of intraocular infection in the ophthalmology department of 8 grade Ⅲ class A hospitals in Zhengzhou from January to June 2020. The correlation between the knowledge, attitude and practice were analyzed by Pearson correlation analysis and the influencing factors of each term were analyzed by multivariate Logistic regression.Results:The scores of knowledge, attitude, practice of all nurses were (26.08 ± 2.46), (67.45 ± 8.48), (50.31 ± 6.67) points, and the scoring rate were (87.0 ± 8.2)%, (84.3 ± 10.1)%, (83.9 ± 9.8)%, respectively. The scores of each dimension of knowledge, attitude and practice were significantly positively correlated ( r values were 0.26-0.42, all P<0.05), respectively. Multivariate Logistic regression analysis showed that education background, professional title and training experience of infection were the influencing factors of knowledge score ( P<0.05), education background, professional title, training experience of infection and demand were the influencing factors of attitude score ( P<0.05), and nursing age and work post were the influencing factors of practice score ( P<0.05). Conclusions:The level of knowledge, attitude and practice of ophthalmic nurses in grade Ⅲ class A hospitals on prevention and control of intraocular infection is overall good. Hospital management department still needs to make reasonable management countermeasures according to personnel characteristics to improve the knowledge, attitude and practice level of ophthalmic nurses and to reduce post-operative intraocular infection.

Objective:To explore the effects of the γ-aminobutyric acid(GABA) neurons and melanin-concentrating hormone (MCH) neurons of the nucleus accumbens (NAc)-lateral hypothalamic area (LHA) neural pathway on the rewarding feeding(palatable food sweat condensed milk) in the obesity rats.Methods:Total 142 male Wistar rats of SPF grade were divided into normal diet (ND) group ( n=68) and high-fat diet induced obesity (DIO) group ( n=74) according to the principle of body mass matching. The rats in the two groups were given normal diet and high-fat diet for 8 weeks. Eight weeks later, 6 DIO rats were randomly selected to observe the nerve projection from GABA neurons in NAc to MCH neurons in LHA by fluorogold retrograde tracing combined fluorescence immunohistochemistry. And the expressions of c-Fos and MCH in LHA after ingestion of sweet condensed milk(rewarding feeding) were observed by fluorescence immunohistochemistry (6 rats in each group). GABA receptor agonist Musimol or GABA receptor antagonist Bicuculine was microinjected into the nucleus of LHA to observe the effect of GABA on rewarding food intake in ND and DIO rats ( n=8 in each group), and the changes of rewarding food intake after blocking MCH signal ( n=8 in each group). SPSS 17.0 was used for statistical analysis, two-way ANOVA and post hoc Bonferroni test were used for comparison among multiple groups, and t-test was used for comparison between two groups. Results:After 8 weeks of high-fat diet modeling, the intake of delicious food in DIO rats was significantly higher than that in ND rats((12.52±2.29) mL, (7.45±1.23) mL, t=4.778, P<0.01) after satiety.The results of fluorogold retrograde tracing combined with fluorescence immunohistochemistry showed that GABA neurons in NAc projected nerve fibers to neurons in LHA, and GABA A receptors in some neurons in LHA coexisted with MCH.The results of NAc-LHA pathway on delicious food intake showed that the interaction between rat group and drug intervention was significant( F=9.869, P<0.01). Simple effect analysis showed that the intake of delicious food after microinjection of Musimol into LHA nucleus of ND rats was significantly lower than that of microinjection normal saline ((4.25±1.38) mL, (7.29±1.49) mL, P<0.01), while the intake of delicious food after injection of Bicuculine was significantly higher than that of microinjection normal saline((10.72±2.11) mL, (7.29±1.49) mL, P<0.05). The intake of delicious food after microinjection of Musimol into LHA nucleus in DIO group was significantly lower than that of microinjection normal saline((3.51±1.77)mL, (13.68±2.95) mL, P<0.01), but there was no significant difference between microinjection Bicuculine and microinjection normal saline ((14.83±3.44) mL, (13.68±2.95) mL, P>0.05). The results of blocking MCH signal on delicious food intake showed that the interaction effect between SNAP-94847 and Bicuculine intervention was not significant ( F=1.468, P>0.05). The main effect of SNAP-94847 intervention was significant ( F=15.880, P<0.01)and the main effect of Bicuculine intervention was significant ( F=6.930, P<0.05). After intracerebroventricular injection of MCH receptor blocker SNAP-94847, the delicious food intake of ND rats was significantly less than that of injection normal saline((4.78±1.72) mL, (7.63±2.77) mL, P<0.05), and it was not affected by pre injection of Bicuculine in LHA ((6.24±2.18) mL, (4.78±1.72) mL, P>0.05). In the DIO rats, the interaction effect between SNAP-94847 and Bicuculine intervention was not significant( F=0.006, P>0.05). The main effect of SNAP-94847 intervention was significant ( F=18.46, P<0.01) and the main effect of Bicuculine intervention was not significant ( F=2.059, P>0.05). After intracerebroventricular injection of MCH receptor blocker SNAP-94847, the delicious food intake of DIO rats was significantly lower than that of injection normal saline((6.89±2.11) mL, (12.19±4.36) mL, P<0.05), and it was not affected by pre injection of Bicuculine in LHA ((8.72±2.26) mL, (6.89±2.11) mL, P>0.05). Conclusion:GABAergic signal in NAc can regulate the expression of MCH in neurons of LHA. In the DIO rats, the sensitivity of MCH neurons in LHA to satiety signal decreases and the hedonic feeding increases.
