Objective: To study significance of detection of serum levels of high sensitive C reactive protein (hsCRP), tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) for assessing patient’s condition in patients with coronary heart disease (CHD). Methods: Serum levels of hsCRP, TNF-α and IL-8 were measured in 78 CHD patients undergoing percutaneous coronary intervention (PCI) before and three months after PCI. Among CHD patients, there were 17 patients with acute myocardial infarction (AMI), 36 patients with unstable angina pectoris (UAP) and 25 patients with stable angina pectoris (SAP). Their levels of above indicators were compared with those of 47 healthy subjects (normal control group). Results: （1）Compared with normal control group, there were significant increase in serum levels of hsCRP [ (1.96±0.60) mg/L vs. (22.43±9.68) mg/L, (18.27±8.56) mg/L], TNF-α [ (11.26±3.82) ng/L vs. (60.12±19.37) ng/L, (40.33±15.48) ng/L] and IL-8 [ (48.26±20.87) ng/L vs. (120.36±33.32) ng/L, (105.92±34.2) ng/L] in AMI group and UAP group before treatment (P<0.01 all), and Pearson linear correlation analysis showed that hsCRP was positively correlated with levels of TNF-α and IL-8 (r=0.873~0.956, P<0.01 all); （2）Serum level of hsCRP in SAP group [(6.04±2.38) mg/L] was significantly higher than that of normal control group (P<0.01); （3）Compared with before PCI, there were significant decrease in serum levels of hsCRP[(13.89±6.13) mg/L vs. (2.06±1.42) mg/L], TNF-α[(38.26±14.27) ng/L vs. (13.76±4.12) ng/L] and IL-8[(98.96±32.9) ng/L vs. (50.12±19.85) ng/L] in CHD patients three-month after PCI (P<0.01 all), and they were no significant difference compared with normal control group (P>0.05 all). Conclusions: Detections of serum levels of hsCRP, TNF-α and IL-8 in CHD patients are of certain significance for diagnosis, treatment and prognosis prediction of CHD.

Objective To discuss the feasibility of biodegradable covered magnesium alloys stent for a rabbit model of lateral aneurysm in the common carotid artery (CCA). Methods The left CCA was ligated in 20 conventional New Zealand rabbits. MRA of the neck was performed 1 month after ligation. The rabbits with thickening of the right CCA and non-or slight thickening of the bilateral vertebral arteries were selected for lateral aneurysm model making. The venous pouch and the right CCA wall by discontinuous extroversion sutures, to form a lateral aneurysm model. The biodegradable covered magnesium alloys stents or Willis covered stents were inserted two weeks after model making. Angiography was performed prior to the procedure, 3, 6 and 12 months after stent implantation to evaluate the disappearance of the aneurysms and patency of the right CCA. The degradation behaviour is invastagated with molybdenum target 2 weeks, 1, 2, 4, 6,9 and 12 months after stent placement. Results The left CCAs were successful ligated in all rabbits. MRA 1 month after ligation showed thickening of the right CCA and non-thickening of the bilateral vertebral arteries in 17 of 20 rabbits. In these animals, the CCA lateral aneurysm model was deemed successful, and biodegradable covered magnesium alloys stents and Willis covered stents were implanted in 9 and 8 aneurysms, respectively. DSA after biodegradable covered magnesium alloys stent placement displayed disappearance of the aneurysms and patency of the CCA in all 9 rabbits during follow-ups. DSA 3 months after Willis stent placement displayed patency of the CCA in 7 rabbits and occlusion of the artery in one. No occlusion of the right CCA was observed on angiography at 6 and 12 months. The degradation of the biodegradable covered magnesium alloys stent was investigated with molybdenum target during follow-ups, and no changes was observed in Willis covered stent. Conclusion Biodegradable covered magnesium alloys stent is a feasible approach for the treatment of a lateral aneurysm in the right CCA.

Objective To investigate the mechanism and role of ?-ray of 103Pd in the treatment of biliary duct cancer.Methods A series of biliary duct cancer cells were treated with different ?-ray dose,and MTT [3-(4,5-dimethy thiazol-2-yl)-2,5-diphenyl terazolium-bromide] technique was used to determine the inhibition rate of ?-ray of 103Pd on the biliary duct cancer cells;and electron micro-technique,DNA agarose gel electrophoresis and flow cytometry to evaluate the morphological characteristics and apoptosis rate of the biliary duct cancer cells were also used.Results The ?-ray radiation of 103Pd resulted in significant inhibition of the biliary duct cancer cells.The features of biliary duct cancer cells apoptosis(e,g:apoptic bodies,DNA ladders band hypodiploid DNA peak) could be seen in the group with lower dosage(5.333mci),and cell necrosis was seen in higher dosage(more than 6.645 mci).Conclusions The ?-ray radiation could induce apoptosis of the biliary duct cancer cells,but with dose dependence,and apoptosis can be an important mechanism for radiation treatment of biliary duct cancer.

Objective To study the influence of walking exercise training on heart function, left heart ventricle structure and plasma brain natriuretie peptide (BNP) concentration in patients with chronic heart failure ( CHF), to explore the sense of exercise training.Methods A total of 223 CHF patients were randomly assigned to a guided rehabilitation group, a non-guided rehabilitation group and a control group.All patients were given basic medicine treatment, and the guided rehabilitation group was administered guided walking exercise training program, while the non-guided rehabilitation group was encouraged to do exercise freely but with no guidance.Blood pressure, 6 min walking distance test, plasma concentration of BNP and echocardiography were measured in all patients before and after exercise training.Results At entry to the study, there was no significant difference among the 3 groups with regard to blood pressure, 6 rain walking distance and BNP level as well as echocardiographic parameters including left ventrieular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDd).A follow-up at the 6th month after intervention, the amount of readmission patients in guided rehabilitation group were significantly less than those in non-guided rehabilitation and control groups ( P < 0.05 ).It was also revealed that the plasma concentration of BNP decreased significantly ( P < 0.01 ) ; LVEF and 6 min walking distance improved significantly ( P < 0.01 ) in the guided rehabilitation group when compared with baseline and 6-month follow-up of the non-guided rehabilitation and control groups.However, there observed no significant change with regard to LVEDd.Conclusion Walking exercise training can improve exercise endurance in CHF patients and is safety; but has no influence on left heart ventricular structure in short time.

Objective:To summarize the clinical characteristics of patients with epilepsy caused by focal cortical dysplasia (FCD), and identify the influencing factors for postoperative seizure controls.Methods:Fifty-seven patients with epilepsy caused by FCD admitted to Department of Neurosurgery, Third Affiliated Hospital of Zhengzhou University from July 2019 to November 2023 were chosen; standard preoperative evaluation, surgery, postoperative management and follow-up were performed. A retrospective study of clinical data, imaging and video electroencephalogram (VEEG) data, surgical approaches, pathological findings, and follow-up data was performed; influencing factors for postoperative seizure controls were analyzed.Results:In these 57 patients with epilepsy caused by FCD, 29 were males (50.88%) and 28 were females (49.12%). Onset age was 30.00 (8.00, 74.50) months, and surgery age was 95.00 (50.00, 138.50) months. Focal to bilateral tonic-clonic seizures (42/57; 73.68%) and epileptic spasms (13/57; 22.81%) were common seizure types. Cranial MRI was positive in 34 patients (59.65%), mainly manifested as abnormal cortical gyri/sulci morphology (17/57; 29.82%). In 43 patients accepted PET-CT, hypometabolic sites were detected in 40 (93.02%), and complete agreement between PET/MRI fusion results and actual lesion sites was noted in 40 (93.02%). FCD type I was noted in 16 patients (28.07%), type II in 39 (68.42%), and type III in 2 (3.51%). By December 2023, 44 (77.19%) had Engel grading I, 4 (7.02%) had grading II, 4 (7.02%) had grading III, and 5 (8.77%) had grading IV. Children with good prognosis (Engel grading I+II) and those with poor prognosis (Engel grading III+IV) showed significant differences in terms of time from first seizure to surgery, positive/negative MRI, and regularity of postoperative ASMs ( P<0.05). Conclusions:Focal to bilateral tonic-clonic seizure is the most common seizure type in patients with epilepsy caused by FCD, and abnormal cortical gyri/sulci morphology is the most common MRI manifestation; PET/MRI fusion imaging is superior to PET-CT or MRI in identifying epileptogenic foci. Poor seizure control can be noted in patients with long onset time to surgery, with negative cranial MRI results, or with irregular postoperative ASMs.

Objective:To assess the clinical effectiveness and safety of Omalizumab for treating pediatric allergic asthma in real world in China.Methods:The clinical data of children aged 6 to 11 years with allergic asthma who received Omalizumab treatment in 17 hospitals in China between July 6, 2018 and September 30, 2020 were retrospectively analyzed.Such information as the demographic characteristics, allergic history, family history, total immunoglobulin E (IgE) levels, specific IgE levels, skin prick test, exhaled nitric oxide (FeNO) levels, eosinophil (EOS) counts, and comorbidities at baseline were collected.Descriptive analysis of the Omalizumab treatment mode was made, and the difference in the first dose, injection frequency and course of treatment between the Omalizumab treatment mode and the mode recommended in the instruction was investigated.Global Evaluation of Treatment Effectiveness (GETE) analysis was made after Omalizumab treatment.The moderate-to-severe asthma exacerbation rate, inhaled corticosteroid (ICS) dose, lung functions were compared before and after Omalizumab treatment.Changes in the Childhood Asthma Control Test (C-ACT) and Pediatric Asthma Quality of Life Questionnaire (PAQLQ) results from baseline to 4, 8, 12, 16, 24, and 52 weeks after Omalizumab treatment were studied.The commodity improvement was assessed.The adverse event (AE) and serious adverse event (SAE) were analyzed for the evaluation of Omalizumab treatment safety.The difference in the annual rate of moderate-to-severe asthma exacerbation and ICS reduction was investigated by using t test.The significance level was set to 0.05.Other parameters were all subject to descriptive analysis.A total of 200 allergic asthma patients were enrolled, including 75.5% ( n=151) males and 24.5% ( n=49) females.The patients aged (8.20±1.81) years. Results:The median total IgE level of the 200 patients was 513.5 (24.4-11 600.0) IU/mL.Their median treatment time with Omalizumab was 112 (1-666) days.Their first dose of Omalizumab was 300 (150-600) mg.Of the 200 cases, 114 cases (57.0%) followed the first Omalizumab dosage recommended in the instruction.After 4-6 months of Omalizumab treatment, 88.5% of the patients enrolled ( n=117) responded to Omalizumab.After 4 weeks of treatment with Omalizumab, asthma was well-controlled, with an increased C-ACT score [from (22.70±3.70) points to (18.90±3.74) points at baseline]. Four-six months after Omalizumab administration, the annual rate of moderate-to-severe asthma exacerbation had a reduction of (2.00±5.68) per patient year( t=4.702 5, P<0.001), the median ICS daily dose was lowered [0 (0-240) μg vs. 160 (50-4 000) μg at baseline] ( P<0.001), the PAQLQ score was improved [(154.90±8.57) points vs. (122.80±27.15) points at baseline], and the forced expiratory volume in one second % predicted (FEV 1%pred) was increased [(92.80±10.50)% vs. (89.70±18.17)% at baseline]. In patients with available evaluations for comorbidities, including allergic rhinitis, atopic dermatitis or eczema, urticaria, allergic conjunctivitis and sinusitis, 92.8%-100.0% showed improved symptoms.A total of 124 AE were reported in 58 (29.0%) of the 200 patients, and the annual incidence was 0(0-15.1) per patient year.In 53 patients who suffered AE, 44 patients (83.0%) and 9 patients (17.0%) reported mild and moderate AE, respectively.No severe AE were observed in patients.The annual incidence of SAE was 0(0-1.9) per patient year.Most common drug-related AE were abdominal pain (2 patients, 1.0%) and fever (2 patients, 1.0%). No patient withdrew Omalizumab due to AE. Conclusions:Omalizumab shows good effectiveness and safety for the treatment of asthma in children.It can reduce the moderate-to-severe asthma exacerbation rate, reduce the ICS dose, improve asthma control levels, and improve lung functions and quality of life of patients.

Objective: To establish a three-dimensional coordinate system that can accurately measure the recurrence rate after orthognathic surgery, and evaluate and analyze the degree of recurrence. Methods : Data from patients who underwent orthognathic surgery in a hospital were selected to reconstruct three-dimensional images with spiral CT. The two researchers used the multiplane assisted positioning method to fix the points three times and screened them using intra-andintreclass correlation coefficients (ICC). Reproducible and accurate landmark points were drawn to establish different coordinate systems and calculate the facial asymmetry index (AI) to determine the coordinate system with the best mid-sagittal plane symmetry. This coordinate system and lateral radiographs were used to separately measure the recurrence rate, and evaluate and analyze the three-dimensional recurrence degree of orthognathic surgery. Results : Ten landmark points that may be repeatedly fixed were obtained, including N (nasion), K (K point), ANS(anterior nasal spine), PNS (posterior nasal spine), Ptm(pterygomaxillary fissure), Gn (gnathion), IZ(IZ point), MZ (MZ point), Ms (mastoideale), Cor (coronion) and and Go (gonion). Three coordinate systems were established, and the most suitable coordinate system was the upper edge point of the left infraorbital foramen. The inner upper edge of the right infraorbital foramen and both sides of the midpoint of the ear points constituted the horizontal plane (HP), which passed through the outermost point of the left zygomatic frontal suture and the outermost point of the right zygomatic frontal suture and was perpendicular to the horizontal plane to constitute the coronal plane (CP). It was perpendicular to the two planes to form a sagittal plane (SP). Two-dimensional and three-dimensional measurements of recurrence were performed on 112 patients, and new three-dimensional recurrence evaluation results were obtained. Less than 40% had low recurrence, 40% to 61% had moderate recurrence, and greater than 61% had high recurrence. Conclusion This study established a three-dimensional coordinate system suitable for measuring the recurrence rate after orthognathic surgery, obtained a new three-dimensional recurrence evaluation result, and provided a clinical experimental basis for evaluating the effect of orthognathic surgery and improving stability.

The fall armyworm (FAW), Spodoptera frugiperda, is a destructive pest native to America and has recently become an invasive insect pest in China. Because of its rapid spread and great risks in China, understanding of FAW genetic background and pesticide resistance is urgent and essential to develop effective management strategies. Here, we assembled a chromosome-level genome of a male FAW (SFynMstLFR) and compared re-sequencing results of the populations from America, Africa, and China. Strain identification of 163 individuals collected from America, Africa and China showed that both C and R strains were found in the American populations, while only C strain was found in the Chinese and African populations. Moreover, population genomics analysis showed that populations from Africa and China have close relationship with significantly genetic differentiation from American populations. Taken together, FAWs invaded into China were most likely originated from Africa. Comparative genomics analysis displayed that the cytochrome p450 gene family is extremely expanded to 425 members in FAW, of which 283 genes are specific to FAW. Treatments of Chinese populations with twenty-three pesticides showed the variant patterns of transcriptome profiles, and several detoxification genes such as AOX, UGT and GST specially responded to the pesticides. These findings will be useful in developing effective strategies for management of FAW in China and other invaded areas.
