Objective To compare the different doses of low-temperature plasma (LTP) on wound healing in BALB/c mice so as to discuss the effects of the optimal dose of low-temperature plasma dealing with wound in mice and the acting mechanism of wound healing.Methods Adoptatmospheric pressure plasma jet discharged by the dielectric barrier was used to treat mouse skin wound.According to the processing time, the wounds were divided into 10s, 20s, 30s, 40s and 50s experimental groups, while naturally healing wounds served as negative controls and the wounds dealt with recombinant human epidermal growth factor served as positive controls.We recorded the wound size every day, observed the histopathological changes, the expression level of type Ⅰ collagen by immunofluorescence, and analyzed the composition of low-temperature plasma jet.Results The wounds with plasma treatment time of 10s, 20s, 30s, and 40s showed significant daily improvement and almost complete closure at days 12, 10, 7, 13, respectively.However, the wounds with plasma treatment time of 50s remained unhealed atday 14.The wounds in positive control group all healed, and the wound healing effect in positive control group could be achieved in 30s group.HE staining and immunofluorescence staining assays showed the optimal result of epidermal cell regeneration, granulation tissue hyperplasia, and collagen deposition in histological aspect at day 7 in 30 s group.The low-temperature plasma jet contained highly reactive free radicals of nitrogen and oxygen, which play an important role in wound healing process.Conclusion Appropriate doses of cold plasma can accelerate wound healing whereas over-doses of plasma can suppress wound healing.The process of wound healing may be related to reactive oxygen and nitrogen species in LTP.

Objective:To evaluate the immunogenicity of recombinant factor H binding protein(fHBP) by detecting serum antibody titer and serum bactericidal antibody test (SBA).Methods:fHBP sequence was selected and synthesized, connected to plasmid pET43.1a, transformed to Escherichia coli BL21(DE3), and expressed two recombinant fHBP proteins, included two subfamilies, fHBPA and fHBPB. After purification, the recombinant fHBP proteins were immunized to rabbits and mice. The immune antiserum titer and the bactericidal titer to epidemic strains of meningococcal bacteria group B were measured by ELISA and SBA respectively. Results:The antiserum titer of fHBP immunized rabbits was greater than 2.0×10 6, and that of immunized mice was not less than 1.0×10 6. fHBP immunized rabbit serum had bactericidal titer more than 1∶128 to 41 strains A subfamily and 20 strains B subfamily in the SBA against 69 endemic strains, and there was no cross-protection between the subfamily bacteria. The bactericidal titers of mouse serum immunized fHBPA to strains A subfamily such as Nm210902 Nm211009、Nm450522 were 1∶1 024, 1∶608、1∶861, to Nm510703、Nm311304、Nm431002 were 1∶234、1∶861、1∶430 respectively, and mouse serum immunized fHBP B to strains B subfamily Nm311302、Nm311304、Nm431002 were 1∶876、1∶274、1∶1858, all of three strains were positive in bactericidal titers. Conclusions:the titer of fHBP antiserum was higher than 1.0×10 6, the bactericidal titer was no less than 1∶128 to 61 epidemic strains, and it has a 94.2% protective effect on 69 meningococcal epidemic strains group B.

Objective: To explore the relationship between prepregnancy body mass index, weight gain during pregnancy with preschool obesity and body composition in offspring, so as to provide evidence for gestational weight gain and childhood obesity prevention. Methods: A total of 1 333 preschool children were recruited from 3 kindergartens in Tianjin from September to December 2020. Structured questionnaire was used to collect children s lifestyle information. Height, weight and body fat mass of children were assessed, and body fat percentage (FM%), fat mass index (FMI) and non fat mass index (FFMI) were calculated. Maternal medical records were collected and the mothers were grouped according to their prepregnancy weight status and weight gain during pregnancy. χ 2 test, t test, linear regression model and Logistic regression were used to analyze the differences of obesity and body composition among different groups. Results: The prevalence of overweight and obesity in preschoolers was 12.7% and 7.7%. After adjusting maternal age and delivery, gestational age, gender, age and lifestyle of children, the correlation between maternal pre pregnancy BMI,gestational weight gain with obesity and body composition indexes of children in preschool age was statistically significant ( P <0.05). For mothers with normal weight before pregnancy, excessive weight gain during pregnancy increased risk of high FM% and high FMI in offspring ( OR=1.81, 1.68, P <0.05). There was no significant correlation between maternal weight gain during pregnancy with offspring obesity and body composition among mothers with prepregnant overweight or obesity. Conclusion Maternal weight status before pregnancy and weight gain during pregnancy are correlated with obesity and body composition in the preschool age of offspring. It is suggested that mothers should maintain appropriate weight status before and during pregnancy.

Objective To explore the effect of intraoperative parathyroid hormone (IOPTH) examination on parathyroidectomy for primary hyperparathyroidism.Methods The clinical data of 41 PHPT patients who received IOPTH monitoring (IOPTH group) from Jan.2009 to Dec.2014 were retrospectively analyzed.The clinical manifestation,examination and changes of parathyroid hormone and calcium before and after operation were collected.Results There were 12 males and 29 females.36 cases had parathyroid adenoma,and 5 cases were parathyroid carcinoma.23 cases were positive in 24 cases of 99Icm-MIBI parathyroid adenoma radionuclide examination,and 2 cases were positive in 3 cases of parathyroid carcinoma radionuclide 99Tcm-MIBI inspection (P＝ 0.213).10 mins after tumor resection,PTH in all cases decreased by 50％ or more than that before tumor resection except for one case of parathyroid carcinoma.23 cases appeared hypocalcemia in 36 cases of parathyroid adenoma after surgery and 2 cases appeared hypocalcemia in 5 cases of parathyroid cancer patients (P＝0.361).No postoperative hoarseness,cough,bleeding occoured.Patients were followed up from 6 to 72 months.Hypocalcemia symptoms recovered 2 weeks to 3 months after surgery.No permanent hypoparathyroidism occured.One case of parathyroid carcinoma died of hypercalcemia 5 months after surgery.The remaining 40 cases survived without recurrence or death.Conclusions Intraoperative PTH monitoring can help doctors analyze whether all the hyperthyroidism glands have been removed,which can help to avoid miss diagnosis of multiple gland disease and unnecessary bilateral neck exploration.This method is highly accurate so it is recommended for routine use in PHPT surgery.

OBJECTIVETo map the gene responsible for nonsyndromic hearing impairment in a consanguineous family.

METHODSFirstly, X chromosome scanning was used to exclude X chromosome. Secondly, candidate gene analyzing and genome scanning were performed by homozygosity mapping. Then, additional markers flanking the tightly linked marker were tested to confirm linkage and decide the candidate region.

RESULTSThe nonsyndromic hearing impairment of this family was autosomal recessive. Twenty-five known genes were excluded. Autosomal genome scanning indicated that D17S1293 was tightly linked with disease gene. And further study mapped the disease gene to a 5.07 cM interval bounded by D17S1850 and D17S1818.

CONCLUSIONThe disease gene of the family is mapped to a 5.07 cM interval between D17S1850 and D17S1818, which is a new locus of autosomal recessive nonsyndromic hearing impairment.
