Objective To study the protective effect of Xingnaojing combined with alprostadil on brain after acute ischemic stroke in rats.MethodsSixty patients with acute ischemic stroke were enrolled in zhejiang xin'an international hospital from March 2014 to March 2016.They were randomly divided into control group and treatment group, 30 cases in each group.The control group received conventional treatment plus alprostadil, the treatment group in the control group based on the combination of Xingnaojing treatment.Two groups of patients after treatment, are given nursing intervention, such as routine diet guidance, nutritional support, health education.The levels of serum oxidative stress (MDA), vascular endothelial growth factor (VEGF) and vascular endothelial growth factor (VEGF) were compared between the two groups before and after treatment.The levels of cerebral blood flow (CBFV) were recorded before and after treatment Observe the adverse reactions during treatment.ResultsAfter 14 days of treatment, the NIHSS score of the treatment group was lower than that of the control group and the ADL score was higher than that of the control group.The difference between the two groups was statistically significant (P<0.05).Before treatment, the oxidative stress indexes MDA and Hcy were no significant difference between the two groups.After treatment, the oxidative stress indexes MDA and Hcy were lower than the control group(P<0.05).Before treatment, the levels of VEGF and CBFV in the two groups were no significant difference between the two groups.After treatment, the levels of VEGF and CBFV in the two groups were significantly higher than those in the control group (P<0.05).The adverse reaction rate between the 2 groups was similar, and there was no significant adverse reaction, there was no significant difference between the two groups.ConclusionXingnaojing combined with alprostadil has a certain clinical effect on acute ischemic stroke, and has a good protective effect on brain tissue after reperfusion.

Paeonol has inhibitory effect on a variety of tumor cells, whereas cadherin is a kind of glycoprotein that is associated with the occurrence and development of different tumor.In this study, the interactions of paeonol and E-cadherin have been investigated by fluorescence spectrometry and atomic force microscopy (AFM).Fluorescence spectrometry results revealed that the addition of paeonol significantly quenched the fluorescence of E-cadherin.Based on the results of the quenching constant, it was inferred that the interaction of paeonol and E-cadherin was a static quenching process.The thermodynamic parameters ΔH and ΔS were calculated to be -4.3×10.5 J/mol and -1.3×10.3 J/(mol·K), respectively, which proved the involvement of weak interactive forces such as hydrogen bond van der Waals force.AFM results revealed that cadherin molecules were assembled into the long-chain structure.The addition of paeonol could significantly disrupt these assembling structures into short chains, which could be ascribed to the damage of the interdigitation model from the adjacent cadherin molecules.All these results reveal that cadherin is an important target of paeonol to modulate its activity.

Background and purpose:Currently, subjective questionaire is the most frequently used methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, while lacking of effective objective examinations. This study aimed to explore effective methods to evaluate swallowing dysfunctions after radiotherapy in nasopharyngeal carcinoma patients, and gain knowledge of the incidence and severity of swallowing dysfunctions. Methods: From Oct. 2013 to Dec. 2013, 128 consecutive outpatients with previously treated nasopharyngeal carcinoma received esophageal barium lfuoroscopy examination at there regularly follow-ups to evaluate swallowing function. Among these patients, 89 were primary treated with intensity modulated radiation therapy (IMRT) and 39 with conventional radiotherapy (CRT). In this study, each patient received esophageal barium lfuoroscopy examination for 3 times with thin, thick and pasty barium and were dynamically observed using X-ray fluoroscopy from front and lateral direction. Swallowing dysfunctions were defined as follows:①The bolus could not be swallowed and blocked in the mouth;②The dilute barium diverted to the glottis or trachea;③Residual barium delayed in the pyriform sinus and vallecula;④The movement of the hyoid bone or epiglottis were restricted;⑤Bolus prolong through the pharynx;⑥Barium slowed down when went though the esophageal entrance. Results:Of the 128 patients, incidence of dysphagia was 60.2%for the entire cohort, 52.8%for IMRT group and 76.9%for CRT group. Incidence of dysphagia for IMRT group was signiifcantly lower than CRT group (P=0.018). Dysphagia incidence within 1 year, 1 to 2 years and more than 2 years after RT were 63.1%, 33.3%and 69.0%, respectively (P=0.019). Conclusion:There was a high incidence of swallowing dysfunction for the nasopharyngeal carcinoma patients treated with radiotherapy and dysphagia incidence decreased when treated with IMRT. Esophageal barium lfuoroscopy examination is objective method to evaluate the incidence and severity of the swallowing dysfunction.

AIM:To study the effect of Hand2 (one of basic helix-loop-helix proteins’ transcription factors) expression on the development of the cardiac tissues in the fetal rats from gestational diabetes mellitus ( GDM) parents, and to investigate the potential pathogenesis of GDM-induced congenital cardiac defects in rats.METHODS: The adult Spra-gue-Dawley female rats were randomly divided into blank control group (n=24), GDM group (n=30), negative control group ( n=30) and insulin intervened group ( n=30) .The GDM model was established by intraperitoneal injection of 2%streptozotocin (STZ, 40 mg/kg body weight) to the pregnant rats on the successive day.The rats in insulin intervened group were injected with intermediate-acting insulin in order to keep the fasting blood glucose in the normal range.The rats in negative control group were injected with citric acid-sodium citrate buffer solution in the same position.Blood glucose and body weight were examined every day 72 h after STZ injection.On E12, E15 and E19, the rats were anesthetized and the embryonic cardiac tissues were collected after caesarean section.The histopathological changes of the cardiac tissues were observed under microscope with HE staining.The expression of Hand2 was analyzed by the method of immunohisto-chemistry.The expression of Hand2 in the cardiac tissues at mRNA and protein levels was determined by real-time fluores-cence quantitative PCR and Western blotting.RESULTS:During the development of embryonic heart, the protein expres-sion of Hand2 in the cardiac tissues was showed dynamic changes.Observed on E12, obviously increased on E15, and at the highest level on E19.Compared with the other 3 groups, the protein and mRNA expression of Hand2 in GDM group was decreased at the time points of E12 and E15.CONCLUSION:The morbidity of fetal cardiac malformation is significantly increased in GDM group, suggesting that Hand2 may be involved in the development of cardiac malformation in GDM.

BACKGROUNDSerine threonine kinase 15 (STK15) is a kind of mitotic kinase. The overexpression of STK15 is significantly associated with carcinogenesis in many tumors, however, its expression and significance in human lung cancer are still unclear. The aim of this study is to investigate the expression of STK15 in squamous cell carcinoma and adenocarcinoma of the lung and to analyze the correlation between STK15 expression and clinicopathological factors.

METHODSThe pattern of STK15 protein expression was detected in 44 squamous cell carcinomas, 36 adenocarcinomas and 20 paracancerous lung tissue samples by immunohistochemistry method using anti-STK15 antibody. The relative quantity of STK15 protein expression was detected by Western blot, and STK15 mRNA expression was detected by RT-PCR in 40 fresh lung cancer samples and corresponding paracancerous lung tissues.

RESULTSPositive expression rate of STK15 protein was 68.75% (55/80) in lung cancer tissues and 0% in paracancerous controls (P < 0.001). STK15 expression was significantly related to differentiation grade of lung cancer (P=0.011), but not to histological classification, TNM stages or lymphatic metastasis (P > 0.05). The relative expression levels of STK15 protein (P < 0.001 ) and STK15 mRNA (P < 0.001) in lung cancer tissues were both significantly higher than those of corresponding paracancerous lung tissues.

CONCLUSIONSThe expression of STK15 protein and STK15 mRNA is significantly higher in lung cancer tissues than that in paracancerous lung tissues. The expression of STK15 correlates with differentiation of lung cancer.

Objective:To analyze the epidemiological features of respiratory syncytial virus (RSV) infection in Beijing, and monitor the sequence variations in RSV glycoprotein (G) gene and clinical features of infected children.Methods:Respiratory tract specimens were collected from children with acute respiratory infection in the Children′s Hospital Affiliated to Capital Institute of Pediatrics from January 1, 2023 to December 31, 2023. RSV-positive specimens screened by multiple nucleic acid testing were subjected to PCR to amplify the full-length RSV G gene. A phylogenetic tree was constructed after gene sequencing to analyze RSV subtypes and trace G gene variants. Clinical data were retrieved from the medical record system to analyze the clinical features of children with RSV infection in Beijing.Results:A total of 5 489 respiratory specimens were collected from 3 046 male patients and 2 443 female patients. The average age of the patients was 4.36 years. A total of 589 RSV-positive specimens (10.7%, 589/5 489) were detected with 349 from male patients and 240 from female patients. The average age of children with RSV infection was (2.51±2.78) years and the median age was 0.48 years. RSV had been circulating among children in Beijing since March 2023 with two epidemic peaks in May (24.6%, 122/496) and December (18.2%, 126/693). The predominant subtype of RSV in the first half of 2023 was subtype A, but it was replaced by subtype B from November 2023. Phylogenetic analysis revealed a novel G gene of RSV subtype B (RSV-B-BA9-954bp) with a length of 954 bp, which belonged to a new cluster in the phylogenetic tree. The percentage of patients admitted to the Intensive Care Unit (ICU) was higher in children with new variant of RSV subtype B infection than in those with common RSV subtype B infection [44.1% (15/34) vs 25.2% (31/123), χ 2=4.600, P=0.032], while the counts of white blood cells and the levels of C-reactive protein were lower in the children with new variant infection ( P<0.05). Conclusions:RSV has been prevalent among children in Beijing since March 2023 with two epidemic peaks. The predominant A subtype is gradually replaced by to B subtype. A new variant of RSV B G gene (RSV-B-BA9-954bp) is detected among the children.
