ABSTRACT
Objective@#To understand the status quo and influencing factors of overweight and obesity in preschool children, and to provide scientific theoretical reference for the prevention and control of overweight and obesity in preschool children in Urumqi.@*Methods@#Stratified cluster sampling method was adopted to select 1 897 preschool children from 10 kindergartens in Urumqi from October to December in 2021 to understand the status quo of overweight and obesity of preschool children by measuring their height and weight. The influencing factors were collected by questionnaire survey, including Chinese preschoolers eating behavior questionnaire, Chinese preschooler s caregivers feeding behavior scale, 3-6 year old children s home nurture environment scale, and characteristics and influencing factors of physical activity among preschool children.@*Results@#The prevalence of overweight and obesity in preschool children was 31.21% (592), including 19.50% (370) overweight and 11.70% (222) obesity.Childhood overweight and obesity detection rates varied significantly by age, sex, child dietary habits, father BMI, maternal BMI, and maternal pre pregnancy BMI ( χ 2=19.63,28.75,9.45,18.21,18.45,19.36, P <0.05). Multivariate Logistic regression analysis showed that gender, children s eating habits, paternal BMI, pregnancy BMI, satiety responsiveness, external eating, initiative eating, weight concerns, behavior restricted feeding, physical activity and family physical activity environment were the influencing factors of overweight and obesity in preschool children( OR =0.52,1.43,1.51,1.44,0.69,0.74,1.35,1.71,0.81,0.96,1.10, P < 0.05 ).@*Conclusion@#Overweight and obesity in preschool children are popular in Urumqi. Education, diet control and scientific exercise should be strengthened to prevent childhood overweight and obesity.
ABSTRACT
The mixture of ketamine and xylazine is widely used for the auditory brainstem response (ABR) measurement. Esketamine is twice as potent as ketamine. Our objective was to assess the influence of esketamine in mice undergoing cochlear function measurement including ABR and distortion product otoacoustic emission (DPOAE) measurement. C57Bl/6J mice were treated with an equivalent dose of analgesia and received either a single intraperitoneal (ip) injection of 100 mg/kg ketamine and 25 mg/kg xylazine or 50 mg/kg esketamine and 25 mg/kg xylazine. Hearing thresholds, peak latencies of waves I and V, and DPOAE thresholds were recorded. Time to loss of righting and time to regain righting were also assessed. We found that hearing thresholds, the peak latencies of waves I and V, and DPOAE thresholds were similar between the two groups (all P>0.05). Time to regain righting was significantly shorter in the esketamine group (P<0.001) than in the ketamine group. We concluded that when using equivalent doses of analgesia, esketamine may be an ideal substitute for ketamine during cochlear function test.

El lupus eritematoso sistémico (LES) es una enfermedad multisistémica con manifestaciones proteicas. La pancreatitis lúpica es la segunda enfermedad más frecuentemente asociada con el abdomen agudo en relación con el LES. Si bien la pancreatitis aguda es rara, es clínicamente importante porque puede ser potencialmente mortal si no se trata de inmediato. En este artículo, describimos el caso de una niña de 10 años que desarrolló pancreatitis asociada a LES después del tratamiento con corticoesteroides que se complicó posteriormente debido a septicemia fúngica. Los signos y síntomas clínicos mejoraron marcadamente después de la administración de glucocorticoides y ciclofosfamida.
Systemic lupus erythematosus (SLE) is a multisystem disease with protean manifestations. Lupus pancreatitis is the second most common disease associated with SLE-related acute abdomen. Although acute pancreatitis is rare it is clinically important because this condition can be life threatening if not treated promptly. Here, we report a case of a 10-year-old girl who developed SLE-associated pancreatitis after steroids therapy that was subsequently complicated by fungal septicaemia. Her clinical symptoms and signs markedly improved after administration of glucocorticoids and cyclophosphamide.

En este artículo, presentamos el caso de una paciente con glomerulonefritis aguda postestreptocócica (GNAPE) y anemia hemolítica autoinmunitaria (AHAI). Además de los signos típicos de la GNAPE, la paciente tuvo un resultado positivo en la prueba de antiglobulina directa y anticuerpos contra la cardiolipina sin que presentara las manifestaciones clínicas típicas del síndrome antifosfolipídico. Este caso genera dudas respecto de la relación entre el estreptococo y el desarrollo de anemia hemolítica autoinmunitaria en los niños. Este caso destaca la posibilidad de que las infecciones estreptocócicas de nuestra paciente podrían haber causado la anemia, ya sea en el contexto de anticuerpos antifosfolipídicos preexistentes o por haber desencadenado el desarrollo de anticuerpos patogénicos, que luego lleva a la presentación clínica de hemólisis. Se presume que, en la paciente, los anticuerpos contra la cardiolipina inducidos por la infección estreptocócica podrían tener una función directa en la presentación clínica de AHAI.
We present a case of acute post-streptococcal glomerulonephritis (APSGN) with autoimmune hemolytic anemia (AIHA). Along with the classic findings of APSGN, the patient had a positive direct antiglobulin test and an anticardiolipin antibody without any typical clinical manifestations of antiphospholipid syndrome (APS). This case raises questions of the relationship between Streptococcus and the development of autoimmune hemolytic anemia in children. Our case highlights the possibility that the streptococcal infections in this patient might be responsible for her anemia, either in setting of underlying antiphospholipid antibodies, or in having triggered the development of pathogenic antibodies, which subsequently leads to the clinical evolution of hemolysis. It is presumed that in our case, the anticardiolipin antibody induced by streptococcal infection may play a direct role in the clinical evolution of AIHA.

OBJECTIVE: Epstein-Barr virus (EBV) is a ubiquitous human γ-herpes virus, which can adapt and evade host immune defense. Dendritic cells (DCs) play a pivotal role in the initiation and maintenance of immune responses. This study investigated the effects of EBV on cord blood monocytes derived DCs (CBDC). METHODS: Monocytes were isolated from cord blood and cultured in medium containing recombinant IL-4 and GM-CSF to induce DCs development. B95-8 supernatant was added in monocytes culture medium for EBV infection at day 0. Phenotypic characterization of DCs, apoptotic cells, and mitochondrial membrane potential (MMP) were detected by flow cytometry. The morphology was observed by Hoechst 33258 staining and TUNEL staining, the expression of X-linked inhibitor of apoptosis protein (XIAP) was detected by Western blotting assay and caspase 3, 8 and 9 activity was measured. RESULTS: Phenotypic characterization of DCs was changed in EBV-treated group. Chromatin condensation and DNA fragmentation were observed in EBV induced CBDC apoptosis. In addition, caspase 3, caspase 8, and caspase 9 activation were enhanced in the EBV-treated group. This was accompanied by the loss of MMP. Furthermore, XIAP expression was down-regulated in the EBV-treated group and compared to mock-infected group. CONCLUSION: These results suggested that EBV could inhibit CBDC phenotypic differentiation, and induce CBDC apoptosis in caspase-dependent manner with involvement of the mitochondrial pathway. This might help EBV to evade host immune responses to establish persistent infection.

In this study,real-time PCR and immunohistochemistry were used to detect coxsakie and adenovirus receptor (CAR) expression.Both localization and quantity were evaluated in the uteri obtained at days post coitus (dpc) 2.5,4.5,6.5,8.5.Outcome of PCR was assessed by 2-△△Ct method.Image Pro-Plus 6.0 software was used for quantifying mean density of CAR expression in immunohistochemical sections.We found relatively weak CAR expression in the mouse uteri during implantation window.PCR and immunohistochemistry revealed highest CAR expression was detected on dpc 2.5 followed by down-regulation of CAR at dpc 4.5 and 6.5 (with significant difference).At dpc 8.5,CAR expression was increased slightly again.It is concluded that during implantation,the expression of CAR mRNA and protein is declined,resulting in the impairment of tight junction between cavity epithelium cells.After implantation window closure,CAR appears again to maintain epithelium stability.CAR might play an important role during embryo implantation procedure.
ABSTRACT
To assess the relationship between pronuclear scoring and day-3 embryo quality and pregnancy outcome and to determine the clinical value of pronuclear stage scoring system in human in vitro fertilization-embryo transfer (WF-ET) program, a pronuclear scoring system was used to score zygotes 16-20 h after insemination during conventional WF or intracytoplasmic sperm injec- tion (ICS1). The embryos were classified into groups Z1, Z2, Z3 and Z4. Comparisons were made of the rates of arrested embryos and excellent embryos on day 3. Comparisons of pregnancy outcome were made only in those patients in whom cohorts of similarly Z-scored embryos were transferred. The results showed that there were less arrested embryos and more excellent embryos on day 3 in groups Z1 and Z2 than those in group Z3 and Z4. More embryos arrested and less excellent embryos developed in group Z4 than group Z3. The clinical pregnancy rates resulting from the transfer of single pronuclear score homologous embryo types were similar among groups Z1, Z2 and Z3. Implanta- tion rates of group Z1 were higher (P<0.05) than that of group Z3. These findings suggests that pro- nuclear scoring can predict developmental ability on day 3 and implantation potential. A evaluation that combines the Z-score and day 3 embryo morphology is useful in the determination of the most viable embryos and the number of embryos for transfer.
ABSTRACT
Summary: In order to compare GnRH agonist with antagonist protocol for the same patient during controlled ovarian stimulation cycles, the in vitro fertilization and embryo transfer (IVF-ET) outcome was retrospectively studied in 81 patients undergoing 105 agonist protocols and 88 antagonist protocols. The results showed that there was no statistically significant difference in duration of ovarian stimulation, number of ampoules, oocytes retrieved, serum estradiol (E2) and progesterone (P) levels,thickness of endometrium, the zygote-and blastocyst-developmcnt rate between GnRH agonist and antagonist protocols (P>0.05). High quality embryo rate was higher in antagonist protocols, but there was no significant difference between two protocols. Implantation rate and clinical pregnant rate were significantly higher in antagonist protocol (15.82% and 30.26%, respectively) than in agonist protocol (5.26% and 10.64% respectively (P<0.05). It was concluded GnRH antagonist protocol probably improved the outcome of pregnancy of older patients with a history of multiple failure of IVF-ET in a GnRH protocol.
