Objective To investigate the effect of 3-n-butylphthalide(NBP)on etoposide-induced senescence in human umbilical vein endothelial cells(HUVECs).Methods HUVECs were divid-ed into blank control group,etoposide group(500 nmol/L etoposide+dimethyl sulfoxide),etopo-side+low-,medium-and high-dose NBP groups(500 nmol/L etoposide+5,10 and 20 μmol/L NBP,respectively).Senescence-related β galactosidase(SA-β-gal)staining was used to observe the change in senescent cell proportion.Real-time quantitative PCR was employed to detect the mRNA levels of senescence-associated secretory phenotype(SASP),such as IL-8,IL-1β,and CXC chemokine ligand 1(CXCL1).Western blotting was applied to measure the expression level of ag-ing-related protein,P21.Immunofluorescence staining was utilized to detect the proportion of pro-liferation-related protein Ki67 positive cells.Results Significantly higher P21 expression(1.00± 0.00 vs 0.59±0.09),larger ratio of SA-β-gal positive cells(29.58±4.51)％vs(11.27±1.18)％,increased mRNA levels of IL-8(2.49±0.11 vs 1.00±0.03),IL-1β(6.32±0.15 vs 1.00±0.03)and CXCL1(2.40±0.24 vs 1.00±0.04),but reduced proportion of Ki67 positive cells(5.95±1.55)％vs(27.38±7.00)％were observed in the etoposide group than the blank control group(P＜0.05).Low-dose NBP treatment decreased the ratio of SA-β-gal positive cells,P21 protein level,and mRNA level of IL-1β,and increased the proportion of Ki67 positive cells when compared with the etoposide group(P＜0.05).Conclusion NBP has an antagonistic effect on etoposide-induced se-nescence of vascular endothelial cells.

Objective:Summarizing and analyzing the rules of access and renewal of drugs in Australia,Japan,South Korea,and Chinese Taiwan,this paper aims to provide experience for the improvement of China's policy on national drug reimbursement list renewal.Methods:Through literature review,expert interviews,and other academic methods,it compares the different experience of drug renewal policy from the perspectives of the type,content,and renewal period.Results:Internationally representative national or regional medical insurance drug renewal policies are broadly categorized into single-drug price-volume agreements,joint price-volume agreements,and efficacy-based risk-sharing agreements.Conclusion:It is recommended that China should introduce new content such as joint measurement for renewal of exclusive drugs,combination consideration of quantity,price,and effectiveness,risk-sharing agreement for renewal of non-exclusive drugs,and placing an upper limit on the rate of reduction for the first renewal in its medical insurance policy.

Objective:To unveil the pathological changes associated with demyelination in schizophre-nia(SZ)and its consequential impact on interstitial fluid(ISF)drainage,and to investigate the thera-peutic efficacy of ursolic acid(UA)in treating demyelination and the ensuing abnormalities in ISF drainage in SZ.Methods:Female C57BL/6J mice,aged 6-8 weeks and weighing(20±2)g,were randomly divided into three groups:control,SZ model,and UA treatment.The control group received intraperitoneal injection(ip)of physiological saline and intragastric administration(ig)of 1％carboxy-methylcellulose sodium(CMC-Na).The SZ model group was subjected to ip injection of 2 mg/kg dizo-cilpine maleate(MK-801)and ig administration of 1％CMC-Na.The UA treatment group underwent ig administration of 25 mg/kg UA and ip injection of 2 mg/kg MK-801.The treatment group received UA pretreatment via ig administration for one week,followed by a two-week drug intervention for all the three groups.Behavioral assessments,including the open field test and prepulse inhibition experiment,were conducted post-modeling.Subsequently,changes in the ISF partition drainage were investigated through fluorescent tracer injection into specific brain regions.Immunofluorescence analysis was employed to examine alterations in aquaporin 4(AQP4)polarity distribution in the brain and changes in protein expres-sion.Myelin reflex imaging using Laser Scanning Confocal Microscopy(LSCM)was utilized to study modifications in myelin within the mouse brain.Quantitative data underwent one-way ANOVA,followed by TukeyHSD for post hoc pairwise comparisons between the groups.Results:The open field test re-vealed a significantly longer total distance[(7 949.39±1 140.55)cm vs.(2 831.01±1 212.72)cm,P＜0.001]and increased central area duration[(88.43±22.06)s vs.(56.85±18.58)s,P=0.011]for the SZ model group compared with the controls.The UA treatment group exhibited signifi-cantly reduced total distance[(2 415.80±646.95)cm vs.(7 949.39±1 140.55)cm,P＜0.001]and increased central area duration[(54.78±11.66)s vs.(88.43±22.06)s,P=0.007]compared with the model group.Prepulse inhibition test results demonstrated a markedly lower inhibition rate of the star-tle reflex in the model group relative to the controls(P＜0.001 for both),with the treatment group dis-playing significant improvement(P＜0.001 for both).Myelin sheath analysis indicated significant demy-elination in the model group,while UA treatment reversed this effect.Fluorescence tracing exhibited a significantly larger tracer diffusion area towards the rostral cortex and reflux area towards the caudal thala-mus in the model group relative to the controls[(13.93±3.35)mm2 vs.(2.79±0.94)mm2,P＜0.001 for diffusion area;(2.48±0.38)mm2 vs.(0.05±0.12)mm2,P＜0.001 for reflux area],with sig-nificant impairment of drainage in brain regions.The treatment group demonstrated significantly reduced tracer diffusion and reflux areas[(7.93±2.48)mm2 vs.(13.93±3.35)mm2,P＜0.001 for diffusion area;(0.50±0.30)mm2 vs.(2.48±0.38)mm2,P＜0.001 for reflux area].Immunofluorescence staining revealed disrupted AQP4 polarity distribution and reduced AQP4 protein expression in the model group compared with the controls[(3 663.88±733.77)μm2 vs.(13 354.92±4 054.05)μm2,P＜0.001].The treatment group exhibited restored AQP4 polarity distribution and elevated AQP4 protein expression[(11 104.68±3 200.04)μm2 vs.(3 663.88±733.77)μm2,P＜0.001].Conclusion:UA intervention ameliorates behavioral performance in SZ mice,Thus alleviating hyperactivity and anxiety symptoms and restoring sensorimotor gating function.The underlying mechanism may involve the improve-ment of demyelination and ISF drainage dysregulation in SZ mice.

Objective:To investigate the effects of early postoperative nutritional management under enhanced recovery after surgery (ERAS) guidelines on nutritional biochemical indicators and length of hospital stay in patients undergoing lumbar fusion surgery. Method:Ninety-four patients who underwent lumbar posterior internal fixation + intervertebral fusion surgery in Department of Orthopedics Ⅲ of Ningxia Medical University General Hospital from January 2020 to March 2021 were randomly divided into an intervention group (n=47) and a control group (n=47). The intervention group received nutritional intervention by a clinical nutritionist at 2 hours after anesthesia recovery, and the control group started to eat liquid diet at 6 hours after anesthesia recovery. The protein-calorie intake, blood glucose, total protein, albumin, hemoglobin, postoperative hospitalization time and total hospitalization time of the two groups were observed. Results:The protein-calorie intake of the intervention group was higher than that of the control group on the day of surgery and the first 3 days after surgery, with statistically significant differences (P<0.05). The blood glucose level of the intervention group was lower than that of the control group on the first day after surgery, with statistically significant differences (P<0.05). The total protein level of the intervention group was higher than that of the control group on the third day after surgery, with statistically significant differences (P<0.05). The albumin and hemoglobin levels of the intervention group were higher than those of the control group on the first and third days after surgery, with statistically significant differences (P<0.05). The incidence of abdominal distension and the length of hospital stay in the intervention group were lower than those in the control group, with statistically significant differences (P<0.05). Conclusion:Early postoperative nutritional management has a certain effect on improving nutritional and biochemical indicators and shortening the length of hospital stay in patients undergoing lumbar fusion surgery.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Excessive sodium/salt intake is the leading dietary risk factor for the loss of healthy life in the Chinese population. The "Healthy China 2030" Action Plan set the goal of reducing salt intake by 20% by 2030. However, salt intake in China is still at a very high level in the world, with adults reaching 11 g/d, more than twice the recommended limit of 5 g/d. The current policies and action plans of China have targeted catering workers, children, adolescents, and home chefs in salt, oil, and sugar reduction actions. However, there are still obvious deficiencies in the coordinated promotion and implementation. This study, therefore, proposed a set of comprehensive strategies (named CHRPS that is composed of communication and education, salt reduction in home cooking, salt reduction in restaurants, reducing salt content in pre-packaged food, and surveillance and evaluation) and key implementation points for further deepening the salt reduction action in China. These strategies were developed based on the main sources of dietary sodium for Chinese residents, the status of "knowledge, attitude and practice" in salt reduction, evidence of effective intervention measures, existing policies and requirements, and the salt reduction strategies of the World Health Organization and experience from some other countries. As a scientific reference, the CHRPS strategies will help the government and relevant organizations quickly implement salt reduction work and facilitate the earlier realization of China's salt reduction goal.

Objectives: To analyze the long-term survival of patients with localized renal cell carcinoma after partical nephrectomy. Methods: The clinicopathological records and survival follow-up data of 2 046 patients with localized renal cell carcinoma, who were treated with partial nephrectomy from August 2001 to February 2021 in the Department of Urology, Sun Yat-sen University Cancer Center, were retrospectively analyzed. There were 1 402 males and 644 females, aged (M(IQR)) 51 (19) years (range: 6 to 86 years). The primary end point of this study was cancer-specific survival. Survival curves were estimated using the Kaplan-Meier method, and the difference test was performed by Log-rank test. Univariate and multivariate Cox analysis were fitted to determine factors associated with cancer-specific survival. Results: The follow-up time was 49.2 (48.0) months (range: 1 to 229 months), with 1 974 patients surviving and 72 dying. The median cancer-specific survival time has not yet been reached. The 5- and 10-year cancer specific survival rates were 97.0% and 91.2%, respectively. The 10-year cancer-specific survival rates for stage pT1a (n=1 447), pT1b (n=523) and pT2 (n=58) were 95.3%, 81.8%, and 81.7%, respectively. The 10-year cancer-specific survival rates of patients with nuclear grade 1 (n=226), 2 (n=1 244) and 3 to 4 (n=278) were 96.6%, 89.4%, and 85.5%, respectively. There were no significant differences in 5-year cancer-specific survival rates among patients underwent open, laparoscopic, or robotic surgery (96.7% vs. 97.1% vs. 97.5%, P=0.600). Multivariate analysis showed that age≥50 years (HR=3.93, 95%CI: 1.82 to 8.47, P<0.01), T stage (T1b vs. T1a: HR=3.31, 95%CI: 1.83 to 5.99, P<0.01; T2+T3 vs. T1a: HR=2.88, 95%CI: 1.00 to 8.28, P=0.049) and nuclear grade (G3 to 4 vs. G1: HR=2.81, 95%CI: 1.01 to 7.82, P=0.048) were independent prognostic factors of localized renal cell carcinoma after partial nephrectomy. Conclusions: The long-term cancer-specific survival rates of patients with localized renal cancer after partial nephrectomy are satisfactory. The type of operation (open, laparoscopic, or robotic) has no significant effect on survival. However, patients with older age, higher nuclear grade, and higher T stage have a lower cancer-specific survival rate. Grasping surgical indications, attaching importance to preoperative evaluation, perioperative management, and postoperative follow-up, could benefit achieving satisfactory long-term survival.

AIM: To investigate the effect of modified Chufeng Yisun Decoction on ocular surface inflammation after pterygium surgery.METHODS: A total of 60 patients(60 eyes)with primary pterygium who underwent pterygium surgery were randomly divided into control group and study group, with 30 cases(30 eyes)in each group. In the control group, patients were treated with pranoprofen eye drops, tobramycin dexamethasone eye drops, and deproteinized calf blood extract eye gel after the surgery. In the study group, patients were treated by oral modified Chufeng Yisun Decoction in addition to the treatments in the control group. The changes of ocular irritation symptoms, ocular inflammatory signs, tear interleukin 6(IL-6)levels, and tear ferning test(TFT)of patients in the two groups were assessed.RESULTS: The visual analogue scale(VAS)in patients of both groups was significantly lower at 2d and 1wk after the surgery than that at 1d after the surgery(all P<0.01), and the VAS of the study group was significantly better than that of the control group at 2d and 1wk after surgery(P<0.01). The ocular signs integrals(OSI)and TFT results of both groups at 1wk were significantly lower than those at 1d after the surgery(all P<0.01), and the OSI and TFT were also lower in the study group than in the control group at 1wk after the surgery(all P<0.01). In addition, the concentration of tear IL-6 in both groups was significantly lower at 1wk after the surgery than 1d after the surgery(all P<0.01), and it was also significantly lower in the study group than in the control group at 1wk after the surgery(P<0.05).CONCLUSION: The combination of Chufeng Yisun Decoction and conventional treatment of western has a better effect on controlling ocular surface inflammation after pterygium surgery.

Objective To investigate the characteristics of hemodynamic changes in superior mesenteric artery(SMA)of patients with acute suppurative appendicitis(ASA)to facilitate the diagnosis of ASA.Methods Ninety-three ASA patients diagnosed by ultrasound and confirmed by pathology in some hospital from January 2015 to December 2022 were enrolled into an ASA group,and 88 soldiers without abnormalities in the annual physical examination at the hospital in 2021 were divided into a control group,and the two groups were compared in terms of SMA hemodynamic indexes including peak systolic velocity(PSV),end diastolic velocity(EDV),resistance index(RI)and systolic/diastolic ratio(S/D).The statistically significant data of the above indexes were selected to draw the ROC curve and obtain the cut-off values.SPSS 22.0 software was used for statistical analysis.Results The PSV was(212±69)cm/s in the ASA group and(118±26)cm/s in the control group,with statistically significant differences(P＜0.05),and the two groups had the differences in EDV,RI,and S/D not statistically significant(P＞0.05).The ROC curve was plotted based on the PSV data,and a cutoff value of 238 cm/s was obtained with an AUC of 0.714.Conclusion Ultrasound examination of SMA hemodynamic changes in suspected ASA patients facilitates a definitive diagnosis and is of guidance for clinical treatment.[Chinese Medical Equipment Journal,2023,44(10):64-67]
