Objective To discuss the effect of blood glucose monitoring during pregnancy and pregnancy outcome in patients with gestational diabetes mellitus (GDM). Methods One hundred and fifty-three GDM patients from July 2007 to July 2008 were analysed.The cases were divided into satisfactory group (74 cases)and unsatisfactory group (79 cases) based on the level of bleod glucose and compared the pregnancy outcome between the two groups. Results The incidences of pre-eclampsia, polyhydramnios, macrosomia, neonatal hypoglycemia, hyperbilirubinemia of satisfactory group were lower than those of unsatisfactory group(5.41% vs 17.72%,4.05% vs 20.25%, 12.16% vs 31.65% , 5.41% vs 20.25%,8.11% vs 30.38%). The difference is statistically significant (P <0.05). The incidence of premature rupture of membranes, premature birth, postpartum hemorrhage, fetal distress of satisfactory group were lower than those of unsatisfactory group, but there was no significant difference between the two groups. Conclusion GDM can cause great harm to maternal and child health, and satisfactory blood glucose control during pregnancy may reduce maternal and child complications.

To improve the water solubility of daidzein, solid inclusion complexes of daidzein with two amino-modified β-cyclodextrins (ACDs), i.e., mono-6-amino-6-deoxy-β-cyclodextrin (NCD) and mono-6-ethylenediamino-6-deoxy-β-cyclodextrin (ENCD), were prepared by the saturated solution method in water under the preparation conditions as follows: the ratio of daidzein/ACD was 3∶1 and the stirring time was 72 h (83% and 67% yields, respectively).The formation of two inclusion complexes was confirmed by x-ray diffractometry (XRD) and themogravimetric (TG) analysis.The inclusion stoichiometry of the inclusion complexes was 1∶1 from the Job plot and their complexation stability constants (KS) were 899.2 and 203.8 L/mol from fluorescence titration, respectively.After formation of inclusion complexes with NCD and ENCD, the water solubility of daidzein was dramatically raised from 8.31 μg/mL to 15.2 and 13.2 mg/mL at 25℃, increasing by 1800-fold and 1500-fold.

Objective To synthesize 131I labeled anti-neuropilin-1 monoclonal antibody A6 (131IA6) and evaluate its biodistribution and imaging in malignant glioma xenografts.Methods (1) A6 was labeled with 131I by Iodogen method under the optimum labeling conditions,then the labeling efficiency,radiochemical purity and stability were measured in vitro.(2) In vitro bioactivity,cellular uptake and receptor affinity of 131I-A6 with U87MG cells were measured.(3) The nude mice bearing human U87MG cells were randomly divided into 5 groups with 5 in each group.The nude mice were sacrificed by cervical dislocation and dissected at 24,48,72,96,and 120 h,respectively,after intravenous injection of 1.2 MBq 131I-A6.The biodistribution of the agent was measured as ％ID/g,and the ratios of tumor/blood (T/B) and tumor/muscle (T/M) were calculated.(4) SPECT/CT imaging was performed in 6 mice including 3 in the competitive inhibition control group at 24,48,72,96,and 120 h post injection.Two-sample t test was used for data analysis.Results (1) The labeling yield of 131I-A6 was (95.46±3.34)％,and the radiochemical purity was more than 95％.At 96 h of incubation in PBS,the radiochemical purity was more than 85％.(2)131I-A6 had rapid accumulation in U87MG cells and reached the peak of (15.80±1.30)％ at 1 h.When the probe was incubated with large excesses of non-radioactive A6,the uptake level of 131I-A6 in U87MG cells was significantly inhibited (t=2.862,P＜0.05).Kd of 131I-A6 binding to NRP-1 was (1.67±0.14) nmol/L in U87MG cells.(3) Biodistribution study showed that the uptake in blood,liver and tumor was (8.00±1.42),(7.68±1.56) and (6.00±1.24) ％ID/g at 24 h,respectively.The uptake in muscle,brain and bone was lower.The T/B and T/M were 0.78±0.10 and 3.20±0.30 at 24 h,and they reached the highest level of 1.87±0.50 and 7.13±0.24 at 120 h.(4) The SPECT imaging showed that the tumors could be visualized at 24 h and delineated more clearly at 120 h post injection of 131I-A6.Conclusions 131I-A6 can be easily synthesized by Iodogen method with high radiochemical purity.The specific tumor uptake of 131I-A6,which correlates with NRP-1 expression in gliomas,suggests that it may be a new promising tumor targeting radiotracer.

Objective To study the methylation status of secreted frizzled-related protein (SFRP) 1 and SFRP2 genes in hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) and the relationship between the methylation status of the two genes and the development of HCC.Methods Using methylation-specific polymerase chain reaction (MSP) to detect methylation status of SFRP1 and SFRP2 genes of 45 specimens of HCC tissue and adjacent non-tumorous liver tissue from HCC patients during operations,and 6 normal liver tissues from patients with cholecystolithiasis or hepatic hemangiomas. The data were analyzed by chi-square test and Fisher exact test. Results SFRP1 gene methylation was detected in 28 HCC tissues and 16 adjacent non-tumorous liver tissues,accounted for 62.2% and 35.6%,respectively;and SFRP2 gene methylation was detected in 23 HCC tissues and 13 adjacent non-tumorous liver tissues,accounted for 51.1% and 28.9%,respectively;while no methylation was detected in 6 samples of normal liver tissues. There was no significant difference between the methylation of SFRP1 and SFRP2 genes in HCC tissues and gender,age,HBV serum markers,types of adjacent non-tumorous liver tissues,metastasis and pathological stage (P＞0.05).The abnormal methylation status between SFRP1 and SFRP2 genes was linear correlated in HCC tissues (r=0.381,P=0.01).Conclusion Hypermethylation of SFRP1 and SFRP2 genes frequently occurs in HBV-related HCC,which may be an important molecular biomarker for prediction of hepatocarcinogenesis in the future.

Objective To explore the the prognostic significance of MMP-9,uPA and uPAR protein expression and its relationship with clinical-pathologic factors in esophageal squamous cell carcinoma treated by radiotherapy.Methods MMP-9,uPA and uPAR protein expression was measured in 59 esophageal car cinomas and 41 peri-carcinoma tissues with immunohistochemistry.The relationship between the protein expression and the clinical-pathological parameters was analyzed,and the prognostic factors in esophageal squamous cell carcinoma treated by radiotherapy alone was evaluated.Results The rates of positive expression of MMP-9.uPA and uPAR were 85%,76%and 78%in esophageal carcinoma and 39%,49%and 44%in peri-carcinoma tissues(x2=22.54,8.04 and 12.18;P=0.000,0.005 and 0.000).The rates of positive expression of MMP-9 was 79%and 100%when the depth of tumor invasion was≤2 am and＞2 cm(P=0.048),respectively.The expression of uPA was significantly correlated with the status of fat interspace between the esophageal lesion and the vertebra in CT seaning image.When the fat interspace existed and disappeared,the rates of strong positive expression was 44%and 70%,respectively(χ2=4.21,P=0.040).The positive expression rate of uPA was significantly correlated with distant metastasis.which was 100%in patients with distant metastasis and 68.89%in those without distant metastasis(χ2=4.12,P=0.042).r11}lepositive expression rate of MMP-9.uPA and uPAR did not affect the prognosis and the short-term result of esoph.ageal carcinoma treated by radiotherapy alone.Conclusions The protein expression of MMP-9,uPA and uPAR may correlate with local infiltration and distant metastasis in esophageal squamous cell carcinoma.Protein expression may not influence the prognosis of esophageal carcinoma treated by radio therapy,though long time followed-up is stil needed.

Cervical cancer has become an important disease that jeopardizes women′s health, causing hundreds of thousands of new cases annually. Human papillomavirus (HPV) is the leading cause for cervical cancer. Since the world′s first HPV vaccine was licensed in 2006, 92 countries around the world have introduced them in national immunization programs. The WHO recommends that scientific economic evaluation should be achieved before the introduction, but this is more difficult for low-and middle-income countries. Therefore, this article introduces a mathematical model recommended by WHO in 2014 to quickly and easily accomplish economic evaluation of HPV vaccine -the PRIME, and take the China′s 2018 data published by International Agency for Research on Cancer (IARC) as an example. The evaluation result shows that the introduction of HPV vaccine in Chinese 12-year-old women is cost-effective.

[Objective]To explore the role of estrogen and estrogen receptor (ER) in the pathogenesis and regulation of non-invasive fungal rhinosinusitis (NIFR).[Methods]Totally 60 patients with NIFS who met the inclusion criteria in Fuzhou Second General Hospital from November 2020 to November 2023 were selected as the NIFS group,while 30 healthy volunteers were recruited as the blank control group. Samples of each group were collected. The number of eosinophils and mast cells in each group were detected by HE staining;ER expression was detected by immunohistochemistry and immunofluorescence;mRNA expression levels of NF-κB,IKK and MASPIN were detected by qPCR;and protein expression levels of NF-κB,IKK and MASPIN were detected by immunohistochemistry and Western blot.[Results]In the NIFS group,the counts of eosinophils and mast cells were significantly increased respectively,compared with those in the control group,and the inter-group differences are statistically significant (P<0.01 and P<0.05,respectively). The Estrogen Receptor (ER) score in the NIFS group was significantly increased compared with that in the control group,and the inter-group differences are statistically significant (P<0.05). Additionally,the average high-density value in the NIFS group was significantly increased compared with that in the control group,and the inter-group differences are statistically significant (P<0.01). The expression levels of NF-κB,IKK,and MASPIN in the NIFS group were significantly increased respectively,compared with those in the control group,and the inter-group differences are statistically significant (P<0.01,P<0.05,and P<0.01,respectively). The mRNA expression levels of NF-κB,IKK,and MASPIN in the NIFS group were significantly increased,respectively,compared with those in the control group (P<0.01). Furthermore,the protein expression levels of NF-κB,IKK,and MASPIN in the NIFS group were increased,respectively,and the inter-group differences are statistically significant (P<0.01,P<0.01,and P<0.05,respectively).[Conclusion]Our results show that the significant increase in the number of eosinophils and mast cells,and in the expression levels of ER,NF-κB,IKK and MASPIN may indicate a significant increase in eosinophil and mast cell infiltration in ER positive patients,and suggest the involvement of estrogen and its receptors in the pathogenesis of NIFS.

OBJECTIVE: To show evidence of the autophagy in hippocampal nerve cells from rats with sepsis-associated encephalopathy (SAE) in vivo and to investigate the expression of microtubule-associated protein 1 light chain 3 (LC3). 
 METHODS: A rat model of sepsis was established by the cecal ligation and puncture (CLP). A total of 60 male Wistar rats (30 days old) were randomly divided into a sham group (n=10) and a CLP group (n=50). At 12 hours after CLP, the electroencephalogram (EEG) and somatosensory evoked potential (SEP) changes in rats were monitored and the neurobehavioral score was measured. According to the occurrence of SAE, the CLP group was further divided into an SAE(+) group and an SAE(-) group. Histopathological changes in hippocampus were observed by hematoxylin-eosin staining. An electron microscope was used to observe autophagosome formation and lysosome activation in the hippocampal nerve cells. Expressions of LC3-I and LC3-II protein were measured by Western blot. 
 RESULTS: Five of 50 rats in CLP group died in 12 hours after CLP. According to the low neurobehavioral score and abnormal EEG and SEP, 16 rats were diagnosed as SAE. The incidence of SAE was 35.56% (16/45). Compared with the sham group or the SAE(-) group, the frequency of α wave in SAE(+) group was significantly decreased at 12 hours after CLP, the δ wave increased, the P1 amplitude decreased, and the latency of SEP waves (P1 and N1) was prolonged (P<0.05). The morphology of hippocampal nerve cells was obvious in a status of edema. Pyramidal cells decreased significantly, even dissolved, and cell arrangement was in disorder in the SAE(+) group. But these cells were normal in the sham group and the SAE(-) group. The structure of hippocampal nerve cells was disordered, and the autophagy, granular matrix and square or rectangular crystals were found in the SAE(+) group. However, there was no autophagy both in the sham group and the SAE(-) group. LC3-II/LC3-I ratio in the hippocampal nerve cells was increased significantly at 12 hours after CLP in the SAE(+) group when compared with that in the sham or the SAE(-) group (P<0.05). 
 CONCLUSION There is autophagy in hippocampal nerve cells from rats with SAE and the LC3-II/LC3-I ratio is increased significantly.
