BACKGROUND: The clinical effect of drug-eluting stent implantation in treatment of coronary artery disease is good, but there may be some differences in the therapeutic effect between different stents. OBJECTIVE:To compare the clinical effect of different stent implantation in treatment of coronary artery disease. METHODS:A total of 278 patients with coronary artery disease were enroled and al underwent coronary artery stent implantation treatment, of which 91 patients underwent implanted rapamycin eluting stent, 92 patients underwent implanted paclitaxel eluting stent, and 95 patients underwent implanted bare metal stents. Al the patients were folowed up for 12 months after stents implantation. The occurrence of adverse cardiac events such as death, myocardial infarction, and the occurrence of coronary restenosis and host reaction were recorded. RESULTS AND CONCLUSION:The rates of coronary artery stenosis, acute myocardial infarction, coronary artery bypass grafting or second-time percutaneous coronary interventional therapy in the paclitaxel eluting stent and rapamycin eluting stent groups were al lower than those in the bare metal stent group (P< 0.05). There were no significant differences in the above indicators between paclitaxel eluting stent and rapamycin eluting stent groups (P> 0.05). There was no significant difference in the mortality between these three groups (P> 0.05). There was no stent shift, shedding, breakage, bad implantation position, leukocytosis, thrombocytopenia and hemolysis in these three groups. These results demonstrate that the therapeutic effects of these two kinds of drug-eluting stents are al good enough, and better than those of bare metal stents.

Objective: To analyze the epidemiological characteristics of hospitalized children with burn in Ningbo from 2013 to 2018,and to provide evidence for developing intervention strategies. Methods: The pediatric burn cases,discharged from the Ningbo Women & Children's Hospital from 2013 to 2018,were registered using the Ningbo Hospitalized Injury Monitoring Report Card,and their distributions of time,places,groups,involved body parts and prognosis were analyzed. Results: There were 3 862 pediatric burn inpatients included in this study,with 2 977（77.08%）cases aged 1-3 years and 2 532（65.65%）nonlocal cases. About 898（23.25%）cases occurred during 9:00-12:00 a.m. and 1 833（47.46%）cases occurred during 17:00- 21:00 p.m. Burns predominantly occurred at home,with 3 810（98.65%）cases. The top three body regions involved were multiple regions,lower limbs and upper limbs with 1 820（47.13%）,835（21.62%）and 541 cases（14.01%）. The proportions of involving multiple regions declined with age（Psingle<0.05）. The proportion of involving multiple regions in nonlocal children was higher than that of local children（P<0.05）. Conclusion Burn is one of the leading causes of child injury-related hospitalization in Ningbo. Home is the main burn scene. Nonlocal and 1-3 year-old children were especially at high risk of burns.

Type Ⅰ sialidosis is a neurosomatic disorder related to the storage of lysosomal and induced by shortage of neuraminidase. It is an autosomal recessive disorder, maybe heterogeneous in its onset, clinical manifestations and prognosis. A case of type Ⅰ sialidosis with a missense mutation in the α-N-acetyl-neuraminidase (NEU1) gene is reported. The patient was characterized by reduced visual acuity, ataxia and subcortical myoclonus. Although the macular cherry red spots were not detected in the male patient, his bilateral visual evoked potential showed severely prolonged latencies of P100, which was consistent with continuous decline of his visions. Finally, he was treated with carbamazepine and clonazepam with moderate improvement in the symptom of myoclonus. In order to make the definite diagnosis, the importance of a clinical history integrating all the patient′s clinical manifestations and the mutation in NEU1 gene was highlighted. Regardless of being an uncommon disorder, the burden for those patients with sialidosis was significant. Therefore, this diagnosis in the relevant setting should always be considered.

Objective: To investigate the trends in mortality of malignant tumors in Ningbo City, Zhejiang Province from 2002 to 2022, so as to provide the evidence for formulating malignant tumor control strategies in Ningbo City. Methods The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Methods: The data regarding the mortality of malignant tumors in Ningbo City from 2002 to 2022 were collected through the Ningbo Municipal Death Cause Monitoring System, and the crude mortality and age-specific mortality of malignant tumors were calculated in Ningbo City. The mortality of malignant tumors was standardized by the population of the sixth National Population Census in China in 2010 (Chinese-standardized mortality) and the world standard population in 1960 (world-standardized mortality). The trends in mortality of malignant tumors were evaluated with annual percent change (APC) and average annual percent change (AAPC). Results: The crude mortality of malignant tumors was 186.43/105 to 221.24/105 in Ningbo City from 2002 to 2022, which showed a tendency towards a rise (AAPC=0.76%), and both the Chinese- (AAPC=-2.64%) and world-standardized mortality (AAPC=-2.74%) appeared a tendency towards a decline (all P<0.05). The world-standardized mortality of malignant tumors presented three changes in Ningbo City from 2002 to 2022, with a more remarkable decline from 2011 to 2018 (APC=-3.53%) than from 2002 to 2011 (APC=-2.10%) and from 2018 to 2022 (APC=-2.00%) (all P<0.05). The annual decline in mortality of malignant tumors was higher in men (Chinese-standardized mortality: AAPC=-2.68%; world-standardized mortality: AAPC=-2.75%) than in women (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%), and higher in urban areas (Chinese-standardized mortality: AAPC=-2.85%; world-standardized mortality: AAPC=-2.92%) than in rural areas (Chinese-standardized mortality: AAPC=-2.45%; world-standardized mortality: AAPC=-2.57%) (all P<0.05). The mortality of malignant tumors appeared a tendency towards a rise with age in Ningbo City, with the highest mortality in residents at ages of 85 years and older (1 447.13/105). Death from malignant tumors were responsible for 31.86% of all causes of death in Ningbo City, and the five most common causes of cancer death included lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer. In addition, the world-standardized mortality of pancreatic cancer (AAPC=3.92%), prostate cancer (AAPC=4.71%), and cervical cancer (AAPC=1.60%) appeared a tendency towards a rise in Ningbo City (all P<0.05). Conclusions The crude mortality of malignant tumors appeared a tendency towards a rise in Ningbo City from 2002 to 2022, while the standardized mortality showed a tendency towards a decline. Management of malignant tumors should be given a high priority among men and rural residents, and lung cancer, liver cancer, gastric cancer, colorectal cancer and esophageal cancer should be emphasized.

Objective: To investigate the trends in incidence and mortality of gastric cancer in Ningbo City, Zhejiang Province from 2011 to 2022, so as to provide insights into improving gastric cancer control strategy. Methods: The incidence and mortality of gastric cancer in Ningbo City from 2011 to 2022 were collected through Ningbo Municipal Chronic Disease and Cause of Death Monitoring System. The incidence and mortality of gastric cancer were calculated, and standardized by the data from the Sixth Chinese National Population Census in 2020 (Chinese-standardized rate) and the world standard population first introduced by Segi in 1960 (world-standardized rate). The trends in incidence and mortality of gastric cancer were evaluated using annual percent change (APC) and average annual percent change (AAPC). Results : The crude incidence of gastric cancer was 45.69/105 in Ningbo City from 2011 to 2022, with no significant changing patterns seen during the study period (AAPC=-0.02%, P>0.05), and the Chinese- and world-standardized incidence of gastric cancer was 28.61/105 and 21.87/105, which both appeared a tendency towards a decline (AAPC=-3.19% and -3.05%, both P<0.05). The crude, Chinese-standardized and world-standardized mortality rates of gastric cancer were 28.56/105, 17.07/105 and 12.57/105, respectively, all showing a tendency towards a decline (AAPC=-3.00%, -6.26% and -6.34%, all P<0.05). The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline in urban (AAPC=-2.72%, -2.53%, -5.91% and -5.96%, all P<0.05) and rural areas (AAPC=-3.61%, -3.53%, -6.79% and -6.89%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer were significantly higher among urban residents than among rural residents. The Chinese- and world-standardized incidence and mortality of gastric cancer all appeared a tendency towards a decline among men (AAPC=-3.18%, -3.00%, -5.82% and -5.91%, all P<0.05) and women (AAPC=-2.98%, -2.90%, -7.12% and -7.12%, all P<0.05), and the Chinese- and world-standardized incidence and mortality of gastric cancer was significantly higher among men than among women. In addition, the crude incidence and mortality of gastric cancer both appeared a tendency towards a rise with age among residents in Ningbo City (both P<0.05). Conclusions The incidence and mortality of gastric cancer both appeared a tendency towards a decline in Ningbo City from 2011 to 2022; however, the incidence and mortality remained high. Males and urban residents should be given a high priority for gastric cancer control, and gastric cancer screening should be strengthened among individuals at ages of 40 years and older.

Objective To compare the outcomes between interstitial cystitis/bladder pain syndrome (IC/BPS)patients treated with three-drug combination (M blockers + alpha blockers + Amitriptyline) and Sodium hyaluronate intravesical instillation.Methods The patients who came to Second Affiliated Hospital of Nanjing Medical University during October 2014 to September 2015 were investigated if they had IC/BPS.According to the treatment plan,27 patients (group A) received three-drug combination (M blocker + alpha blockers + Amitriptyline)therapy.Thirty-eight patients recelved instillation of sodium hyaluronate (40 mg/50 ml) therapy (group B).Intravesical instillations were performed weekly in the first 6 weeks,and monthly until sixth month.Interstitial cystitis symptom index,interstitial cystitis problem index,overactive bladder symptom score,visual analogue scale/score,the maximum urination and self-rating depression scale were assessed at baseline and the sixth month.Measurement data were expressed as ((x) ±s),t test was used for comparison between groups,and paired t-test was used for comparison of paired data.Results There were 65 patients.Age range was 25-73 years,course of disease (2-99 months),average age (51.4 ± 13.5),average duration (39.8 ± 31.0) months,of which 9 male (13.8％) and 56 female (86.2％) patients.The group A variation of ICSI、ICPI、OABSS、VAS、SDS and maximum urination were 3.7 ± 2.4、1.3 ± 1.5、1.2 ± 1.3、2.1 ± 1.5、3.1 ± 4.5、74.6 ± 52.4,The variation of group B ware 6.8 ± 3.6、5.0 ± 3.8、2.5 ± 1.8、2.8 ± 1.7、8.9 ± 6.4、109.0 ± 81.1.The improvement in ICSI,ICPI,OABSS,SDS of group B were higher than group A (P ＜ 0.05).Conclusion IC/BPS seriously affect the quality of life and the patients are prone to depression.The sodium hyaluronate intravesical instillation therapy could achieve more effect than the three-drug combination therapy.

Objective:To explore the effects of genotypes of one-carbon metabolism (OCM)-related enzyme single nucleotide polymorphisms (SNPs) sites and anti-epileptic drugs on OCM metabolite levels in epileptic patients, and to screen valproic acid (VPA) teratogenic susceptibility genes.Methods:Three hundred and seventy-two epileptic patients, admitted to our hospital from January 2019 to December 2020, were enrolled in the study; patients taking VPA, levetiracetam (LEV), lamotrigine (LTG) or oxcarbazepine (OXC) for more than 6 months without attack during regular medication were classified as VPA group ( n=95), LEV group ( n=61), LTG group ( n=57) and OXC group ( n=70); firstly diagnosed epileptic patients who had never taken antiepileptic drugs or had not taken antiepileptic drugs in the previous 6 months were assigned into blank control group ( n=89). Plasma folic acid (FA), vitamin B12 (VitB 12) and homocysteine (Hcy) levels were determined by automatic chemiluminescence immunoassay, and genotypes of OCM-related enzyme SNPs sites were detected by Sequenom iPLEX. Results:(1) As compared with LEV group and blank control group, VPA group had significantly decreased FA level and significantly increased Hcy level ( P<0.05). (2) Patients with DNA methyltransferase (DNMT) 3a rs12987326(-178G>A) GA type had significantly higher Hcy level than those with GG type ( P<0.05); patients with DNMT1 rs2288350(82G>C) GC type had significantly higher Hcy level than those with GG type ( P<0.05); patients with DNMT1 rs75616428 (55850G>C) GC type had significantly lower VitB 12 level than those with GG type ( P<0.05). Patients with DNMT1 rs1863771(128G>A) GA+AA type had significantly higher FA level than those with GG type, patients with folate receptor 2 rs2298444(59T>C) CT+CC type had significantly higher Hcy level than those with TT type, patients with 5,10-methylenetetrahydrofolate reductase rs1801131(1298A>C) AC+CC type had significantly higher Hcy level than those with AA type, and patients with DNMT3a rs6722613(2327C>T) CT+TT type had significantly lower VitB 12 level than those with CC type ( P<0.05). Conclusions:Decreased FA and increased Hcy levels can be noted in epileptic patients who used VPA; some gene variations in SNPs of OCM also affect the OCM metabolite levels in epileptic patients. Epileptic patients during pregnancy should avoid using VPA or detecting SNPs genotypes before medication to reduce the incidence of fetal malformation.

Leptin, an adipocyte-derived peptide hormone, has been shown to facilitate breathing. However, the central sites and circuit mechanisms underlying the respiratory effects of leptin remain incompletely understood. The present study aimed to address whether neurons expressing leptin receptor b (LepRb) in the nucleus tractus solitarii (NTS) contribute to respiratory control. Both chemogenetic and optogenetic stimulation of LepRb-expressing NTS (NTS^LepRb) neurons notably activated breathing. Moreover, stimulation of NTS^LepRb neurons projecting to the lateral parabrachial nucleus (LPBN) not only remarkably increased basal ventilation to a level similar to that of the stimulation of all NTS^LepRb neurons, but also activated LPBN neurons projecting to the preBötzinger complex (preBötC). By contrast, ablation of NTS^LepRb neurons projecting to the LPBN notably eliminated the enhanced respiratory effect induced by NTS^LepRb neuron stimulation. In brainstem slices, bath application of leptin rapidly depolarized the membrane potential, increased the spontaneous firing rate, and accelerated the Ca²⁺ transients in most NTS^LepRb neurons. Therefore, leptin potentiates breathing in the NTS most likely via an NTS-LPBN-preBötC circuit.

The nucleus tractus solitarii (NTS) is one of the morphologically and functionally defined centers that engage in the autonomic regulation of cardiovascular activity. Phenotypically-characterized NTS neurons have been implicated in the differential regulation of blood pressure (BP). Here, we investigated whether phenylethanolamine N-methyltransferase (PNMT)-expressing NTS (NTS^PNMT) neurons contribute to the control of BP. We demonstrate that photostimulation of NTS^PNMT neurons has variable effects on BP. A depressor response was produced during optogenetic stimulation of NTS^PNMT neurons projecting to the paraventricular nucleus of the hypothalamus, lateral parabrachial nucleus, and caudal ventrolateral medulla. Conversely, photostimulation of NTS^PNMT neurons projecting to the rostral ventrolateral medulla produced a robust pressor response and bradycardia. In addition, genetic ablation of both NTS^PNMT neurons and those projecting to the rostral ventrolateral medulla impaired the arterial baroreflex. Overall, we revealed the neuronal phenotype- and circuit-specific mechanisms underlying the contribution of NTS^PNMT neurons to the regulation of BP.
