Objective To evaluate the effects ofbeta-endorphin (β-EP) and substance P (SP)with sedative and analgesic drugs on mechanical ventilated patients. Methods Twenty-eight mechanical ventilated patients were randomly divided into two groups: midazolam group (M group, 14 cases) and midazolam combined with fentanyl group (M + F group, 14 cases). Eight healthy persons were as control group (C group). The sedative target was VAS≤3 scores and Ramsay 2-4 scores. The levels of serum β -EP and SP were tested before sedation and 12, 24 h after sedation in mechanical ventilated patients and at 8 Am in C group. The sedation levels were evaluated and the hemodynamie and respiratory parameters were recorded before sedation and 1, 12, 24 h after sedation in mechanical ventilated patients. The oxygenation index was measured before sedation and 1,12, 24 h after sedation. Results The levels of serum β -EP and SP in M and M+F group were significantly higher than those in C group(P< 0.05). After sedation, the level of SP in M+F group [(101.42 ± 12.46) ng/L]was significantly lower than that in M group [(132.72 ± 23.82) ng/L] (P < 0.05). Compared with before sedation, there were significant differences in heart rate, VAS and Ramsay scores between M group and M+F group (P< 0.05). Compared with M group, pressure airway and respiratory rate at 12, 24 h and total after sedation were lower in M+F group (P <0.05). The amount of serum SP in mechanical ventilated patients. Fentanyl improves the ventilator synehron and reduces the dose of midazolam.

OBJECTIVETo analyze the differences in serum proteomic profiles between patients with silicosis and chronic bronchitis and to investigate the pathogenesis, clinical diagnosis, and treatment of these two disease.
METHODSSerum samples from patients with stage I silicosis and chronic bronchitis were collected. Two-dimensional gel electrophoresis was performed and protein plots with expression differences higher than 2-fold were identified and further analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.
RESULTSCompared with the silicosis group, the chronic bronchitis group had 11 up-regulated proteins and 23 down-regulated proteins. The chronic bronchitis group had high expression of proteins such as interferon beta precursor, apolipoprotein precursor, and transforming growth factor beta1 precursor. The silicosis group had high expression of proteins such as interleukin-6, granzyme A, cathepsin G, and glycoprotein precursor.
CONCLUSIONThe differentially expressed proteins are mainly involved in the activity of serine enzymes, cytotoxicity, inflammation response, and apolipoprotein transfer and play different roles in silicosis and chronic bronchitis.

Objective:To explore the application value of guide tube fenestration and drainage technology in intracranial artery stenting surgery.Methods:A total of 120 patients with symptomatic intracranial atherosclerotic stenosis admitted to the Xingtai Third Hospital from January 2021 to December 2022 were selected and randomly divided into an observation group ( n=60) and a control group ( n=60). Both groups were treated with intracranial artery stenting, with the observation group receiving guidance catheterization and window opening technique during the surgery. Two groups of surgeries were observed and compared: the degree of vascular stenosis before and after surgery, the Montreal Cognitive Assessment Scale (MoCA) scores before and one month after surgery, intraoperative complications, and prognosis. Results:The surgical time and catheter placement time in the observation group were (110.20±23.32)minutes and (11.32±2.01)minutes, respectively, which were significantly shorter than those in the control group (all P<0.05). The stent placement rate and operation success rate in the observation group were 95.00% and 96.67%, respectively, significantly higher than those in the control group (all P<0.05). The degree of postoperative vascular stenosis in the observation group was (32.29±7.11)%, significantly milder than that in the control group [(44.43±8.15)%, P<0.05]. One month after surgery, the MoCA scores of both groups improved significantly compared to before surgery (all P<0.05), and there was no statistically significant difference between the groups ( P>0.05). There was no statistically significant difference in the incidence of collateral circulation occlusion and vascular rupture between the two groups (all P>0.05). During the follow-up period, there was no statistically significant difference in the incidence of restenosis, intracranial hemorrhage, and recurrent ischemic stroke between the observation group and the control group (all P>0.05); The good prognosis rate of the observation group was 73.33%, significantly higher than that of the control group (53.33%, P<0.05). Conclusions:The application of guided catheter fenestration technique in intracranial artery stenting has good value, which is beneficial for improving the stent placement rate and operation success rate, and improving the degree of vascular stenosis.

Objective:To study the relationship and the role of leptin in children with biliary atresia and hepatic fibrosis to provide a treatment basis for these patients.Methods:The clinical data of children with biliary atresia or congenital biliary dilatation (CBD) who underwent surgical treatment at the Department of General Surgery of Tianjin Children's Hospital from August 2019 to August 2021 were retrospectively analyzed. Of 31 children included in this study, there were 14 males and 17 females, with age of 60 (30, 63) d. Children with biliary atresia served as the study group ( n=26) and children with CBD served as the control group ( n=5). Leptin protein, α-smooth muscleactin (α-SMA) and phosphorylation of extracellular-regulated protein kinase 1/2 (p-ERK1/2) in liver tissues were detectd by immunohistochemistry (IHC). The expression level of leptin mRNA in liver tissues were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results:The average optical density values of leptin protein, α-SMA protein and p-ERK1/2 protein in the liver tissues of children in the study group were significantly higher than the control group ( P<0.05). The expression levels of leptin, α-SMA and p-ERK1/2 in liver tissues of children with biliary atresia significantly increased with increase in fibrosis degree ( P<0.05). The expression level of leptin in liver tissues of children with biliary atresia was positively correlated with the liver fibrosis grade ( rs=0.876), α-SMA ( r=0.723) and p-ERK1/2 ( r=0.725) ( P<0.01). The results of qRT-PCR showed that the content of leptin mRNA in liver tissues of children with biliary atresia was significantly higher than that of children with CBD ( P<0.05). Conclusion:Expressions of leptin increased with aggravation of degrees of hepatic fibrosis in biliary atresia. Leptin may be involved in activation of HSCs through the ERK1/2 signaling pathway in the process of hepatic fibrosis due to biliary atresia.

Objective To examine the correlation between the gene of phosphate and tension homology deleted on chromosometen (PTEN gene) polymorphism and schizophrenia (SCZ) associated with the type 2 diabetes mellitus (T2DM ) in Shanghai Han population. Methods The study recruited 591 long-stay schizophrenic inpatients including 304 with and 287 without type 2 diabetes mellitus, 206 patients with the type 2 diabetes mellitus and 205 normal subjects from Shanghai Han population. SNPs of PTEN gene (rs1234225, rs12569998, rs1234223) were genotyped by using Taqman genotyping. The frequency distributions of allele, genotype and haplotype between groups were analyzed. Results There were significant differences in the frequency of rs1234223 genotype (P=0.01) and allele distribution (P=0.02) between the SCZ with type 2 diabetes mellitus group and the SCZ without type 2 diabetes mellitus group. The difference of genotype frequencies remained statistically significant (P=0.03) but the allele distribution was not (P=0.06) after Bonferroni correction. Haplotype analysis showed that TTC haplotype was less common in the SCZ with type 2 diabetes mellitus group than in the SCZ without type 2 diabetes mellitus group (P=0.02). Conclusions PTEN gene may be a susceptibility gene for schizophrenia with type 2 diabetes mellitus in Chinese Han population. The TTC haplotype may be a protective factor for schizophrenia with type 2 diabetes mellitus.

Objective To explore the relationship between the serum neuropeptide Y (NPY) levels and the pathogenesis,therapeutic intervention of schizophrenia. Methods One hundard twenty-five patients with schizophrenia (case group) with no medication for at least 4-week and 136 healthy controls (control group) were evaluated by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Positive and Negative Syndrome Scala (PANSS). Simultaneously blood tests were performed to detect serum NPY levels. In the case group, PANSS was evaluated and blood collected again after 4 weeks of treatment with olanzapine. Result At the baseline,the serum NPY concentration was significantly lower in the case group than in control group (t=-5.79, P<0.01). The scores of RBANS and its factors were significantly lower in the case group than in control group (all P<0.01). The concentration was positively correlated with the score of the attention factor for RBANS scale (r=0.20, P=0.04). After treatment with olanzapine for 4 weeks,the serum NPY level in the case group was significantly increased (t=-2.23,P=0.03).The scores of PANSS total scale and subscale were significantly decreased(all P<0.01).There was no significant correlation between alterations of the serum level of NPY and PANSS total or subscale scores from baseline to 4-week (all P>0.05). Conclusion The present study has revealed a significant decrease in serum NPY levels in patients with schizophrenia which can be attenuated by treatment of Olanzapine.The action of Olanzapine may be related to the mechanism of action of Olanzapine.However,there is no correlation between alterations of the serum level of NPY and the improvement in the patientˊs clinical symptoms.
