Objective To investigate the effect on thyrotropin (TSH) levels of pregnant women and their newborns in different delivery ways. Methods The serum TSH levels of 213 pregnant women and the umbilical cord blood TSH levels of their newborns (140 cases from normal vaginal delivery, 38 cases from cesarean section, 35 cases from low forceps delivery) were tested by immunoradiometric assay. Urinary iodine was detected from pregnant women before delivery. Results In pregnant women, the mean serum level of TSH in the forceps group [(4 13?0 69) mU/L] was significantly higher than those of the normal birth group [(2 58?0 87) mU/L, P

Abstract: Cell death is a fundamental biological phenomenon that is essential for the survival and development of organisms. Cell death can be either a spontaneous programmed process by the host or an accidentally triggered process. According to the different signaling pathway activated by various stimulates, programmed cell death exhibits the lytic or non-lytic morphology. For example, apoptosis, a typical non-lytic form of cell death, exhibits cell shrinkage and induces the formation of apoptotic bodies. Pyroptosis mediated by cysteine-containing aspartate-specific protease-1/11 (caspase-1/11) and necroptosis can induce inflammatory reactions and promote cell lysis to release inflammatory cytokines via triggering the pore-forming mechanism of the cell membrane, representing a typical modes of lytic cell death. In addition, the release of reactive oxygen species caused by the damaged mitochondria may further trigger ferroptosis during the pathogen infection. Programmed cell death can play an immune defensive role by eliminating infected cells and intracellular pathogens and stimulating the innate immune response through the resulting cell corpses. Here, we discuss the molecular mechanisms of five programmed cell death pathways: apoptosis, pyroptosis, ferroptosis, necroptosis and PANoptosis. We describe their roles in the innate immune defense against bacterial infections and give a brief statement of the interactions between the different programmed cell death, hoping to provide new insights for in-depth study of the pathogenic mechanisms of infectious diseases.

Objective To evaluate the impact of chronic hepatitis B virus (HBV) infection on the outcome following resection for intrahepatic cholangiocarcinoma (ICC) patients.Methods The clinicpathological data of 60 consecutive operated ICC patients were collected.These patients were divided into group A with HBV infection,represented by serum positive hepatitis B surface antigen (HBsAg),group B with hepatitis B surface antibody (HBsAb) positive,and group C with all serum marker of HBV negative.The overall survival rate was evaluated.Results The 1-and 3-year overall survival rate and median survival of three groups were 50％ vs 53％ vs 29％ ; 22％ vs 18％ vs O; and 12.0 m vs 12.0 m vs 6 m,respectively.The difference was statistically significant(P =0.037).Multivariate analyses revealed that the preoperative serum level of TIBL,tumor location,HBV infection or injection of hepatitis B vaccine,hepatolithiasis and adjuvant chemotherapy were related to the prognosis.Conclusions HBV infection or injection of hepatitis B vaccine is favorable independent factor for prognosis of patients with intrahepatic cholangiocarcinoma after resection.

Objective To analyze the side effects of in-vitro amplification human leukocyte antigen (HLA)-haploidentical donor immune cell infusion(HDICI) in childhood malignant patients,and to provide the basis for how to nurse these patients.Methods From September 2011 to September 2012,twelve hospitalized childhood malignant patients were recruited in Cancer Center of Sun Yat-sen University,and they received a total of 92 times of HDICIs for immunotherapy.Side effects were carefully observed both during and 2 hours and 24 hours after each infusion,and we also provided psychological nursing,pre-infusion nursing,side effect analysis and corresponding care during infusion,post-infusion education and follow-up for every childhood patient.Results Among 92 times of HDICIs,fever occurred in 20 cases,of whom 6 cases were with chills,1 case with febrile convulsion,all achieved remission after receiving symptomatic treatment.5 cases were also recorded with a slight change of mood.Vital signs were all stable both during and after every HDICIs; and no nausea,vomiting,abdominal pain,diarrhea,rash,swelling or allergic reaction was observed.Neither change of the hemogram nor biochemical indexes was recorded before or after every course of HDICI.Conclusions Our study showed that HDICIs for immunotherapy in childhood malignant patients were safe,and during the whole infusions,much attention should be paid both for psychological nursing,pre-infusion anti-anaphylactic treatment,temperature monitoring,discovery of the precursor of febrile convulsion promptly,symptomatic treatment against corresponding side effects,and post-infusion education and follow-up,all those above are of great importance for childhood malignant patients who received HDICIs for immunotherapy successfully.

ObjectiveTo investigate the psychology of the children with lip and palate cleft and their social environment.Methods700 patients with lip and palate cleft of 0～24 years old were investigated to the harmonization with their parents and their social environment using questionnaire, so as their psychology using Symptom Checklist 90 (SCL-90) in the follow-up after operation.ResultsThe score of SCL-90 was higher in the patients above 6 in some dimension compared with the normal. Their parents seemed to exclude them, and they felt uncomfortable to the others around them.ConclusionThere were a lot of problem of the psychology in patients with lip and palate cleft above 6, and they get poor support from their social environment.

Objective To investigate the diagnostic value of CT-guided craniocerebral puncture biopsy, and to discuss its clinical safety. Methods During the period from April 2013 to June 2014 at authors’ hospital CT-guided craniocerebral puncture biopsy was carried out in 23 patients. All patients had clinical symptoms or signs of nervous system. Imaging examination revealed that all patients had intracranial space-occupying lesions. CT-guided craniocerebral puncture biopsy was performed to make pathological or bacteriological examinations. The results were statistically analyzed. Results In this group of patients, definite pathological diagnosis was made in 19 cases, biopsy positive diagnosis rate of biopsy was 82.6% (19/23), among them oncology-pathological diagnosis was obtained in 14 cases (60.9%), mainly including glioma, non-Hodgkin lymphoma, dysembryoplastic neuroepithelial tumor, choroid plexus papillary tumor, epidermoid cyst, etc. Non-neoplastic lesion was confirmed in 5 cases (21.7%), including suppurated meningitis, cerebral gliosis hyperplasia, cerebral telangiectasis, etc. Small amount of subdural hemorrhage was observed in one case (4.3%). No severe complications, such as intracranial infection or epilepsy, occurred in all patients. Conclusion CT-guided craniocerebral puncture biopsy is minimally-invasive with fewer complications, it can provide definite diagnosis for intracranial lesions, therefore, this technique has a broad development prospect in clinical practice.

Objective To screen and identify effective small interfering RNA (siRNAs) targeting the conserved 5’ untrans-lated region (UTR) of the enterovirus 71 (EV71) genome. Methods Double-stranded siRNAs were designed to target the 5’UTR of the EV71 genome. The cytotoxicity effect of siRNAs on rhabdomyosarcoma (RD) cells was evaluated. The cytopathic effect on EV71-infected RD cells was observed under phase-contrast microscopy and the effective siRNAs were screened out by cell viability assay and real-time TaqMan RT-PCR assay. Results All the siRNAs did not exhibit any cytotoxic effects on the viability and growth of RD cells. Transfection of si-1 and si-2 targeting the 5’ UTR in EV71 genome into RD cells signiifcantly delayed and alleviated the cytopathic effects of EV71 infection, increased cell viability and reduced the EV71 RNA transcripts. And the inhibitory effect of si-1/si-2 on EV71 replication was sequence-speciifc. Conclusions The 2 siRNAs (si-1 and si-2) targeting the conserved 5’UTR of the EV71 genome may have broad spectrum antiviral effects on many epidemic EV71 strains.

Objective:To investigate the association of Subclinical Carotid AtheroSclerosis (SCAS) and prediabetes or Diabetes Mellitus (DM)in the healthy people.Methods:From September 2018 to June 2019, participants who underwent physical examination in the Health Management Center of Beijing Tiantan Hospitial were enrolled consecutively. The baseline characters were collected prospectively. Carotid Ultrasound was evaluated by radiologists according to the standard operating protocol. Univariable analysis and multivariable logistic analysis were used to estimate the association of prediabetes or DM with SCAS.Results:Totally 401 participants were eligible and enrolled. The mean age was (52.2±10.4) years and 43.7% (252/401) of them were females. The prevalence of DM and SCAS were 16.4% (66/401) and 48.9% (196/401) respectively. In the univariate analysis, elder age (≥60 years old) ( OR=5.93, 95% CI: 3.86-9.09, P<0.001), hypertension ( OR=2.76, 95% CI: 1.84-4.15, P<0.01), prediabetes( OR=1.67, 95% CI: 1.08-2.58, P<0.05) and DM ( OR=3.60, 95% CI: 1.97-6.58, P<0.01), cigarettes smoking ( OR=2.64, 95% CI: 1.82-3.81, P<0.001), lower HDLlevel<1.04 mmol/L ( OR=1.58, 95% CI: 1.04-2.42, P<0.001) and hyperhomocysteinemia (≥15 μmol/L)( OR=1.69, 95% CI: 1.17-4.04, P<0.01) were associated with higher prevalence of SCAS. On the contrary, female sex ( OR=0.53, 95% CI: 0.39-0.74, P<0.001) was associated with lower prevalence of SCAS. In the multivariable logistic analysis, elder age(≥60 years old) ( OR=6.04, 95% CI: 3.13-11.7, P<0.01), hypertension ( OR=2.14, 95% CI: 1.13-3.87, P<0.05), cigarettes smoking ( OR=2.19, 95% CI: 1.21-3.98, P<0.05) and DM ( OR=2.32, 95% CI: 1.16-4.67, P<0.05) were associated with SCAS independently. The association between prediabetes and SCAS was not statistically significant. Conclusions:DM is independently associated with SCAS in neurological healthy people, while prediabetes tended to increase the risk of SCAS.

Obgective To investigate the impact of different ways and doses of recombinant human interferon o1b(rhIFN-α1b) on antiviral effect on respiratory syncytial virus(RSV)-effected mice and signal pathway of JAK/ STAT.Methods Forty-eight mice were divided randomly into 6 groups,negative control group,RSV-infection model group,12.5,25.0,50.0 μg rhIFN-α1 b atomization inhalation of intervention group,and 12.5 μg rhIFN-α 1 b injection of intervention group.After continuous drug therapy for 5 days,the left lung tissues of mice were aseptically dissected in the sixth day.Then it were observed lung tissue pathology changes by optical microscope,and expression of STAT1 and STAT2 protein with laser scanning confocal microscopy.Results It was observed that RSV-infection model mice's lungs had significant inflammatory injury under light microscope.After treatments of rhIFN-α 1b,it showed that the mice lung tissue had recovery of inflammation on different degrees.The group of inhaled rhIFN-o1b 50.0 μg was damaged on lightest degree.There were statistically significant differences between each group (all P ＜ 0.05).The expression of STAT1 and STAT2 protein in RSV-infection model mice's lungs decreased remarkably under fluorescene microscopy.Treatments of rhIFN-α 1b increased the expression of STAT1 and STAT2 inhibited by RSV-infection.The expression of STAT1 and STAT2 protein of the inhaled rhIFN-α1b 50.0 μg group increased significantly.The differences between groups were statistically significant(all P ＜ 0.05).Conclusions rhIFN-α 1 b played an important role in anti-RSV effects,simultaneously,it could improve the activity of JAK/STAT signal pathway inhibited by RSV-infection.The treatment effect of rhIFN-α 1b deliveried by atomization inhalation was better than that of intraperitoneal injection.And curative effect is proportional to the atomization inhalation dose within a certain range.
