ABSTRACT
Objective:To investigate the effect of early selective reduction of twin pregnancies or spontaneous reduction on the improvement of clinical outcome in IVF-ET treatment.Methods:The clinical data of 6535 cycles(6535 cases)of single or twin pregnancy obtained from fresh and frozen-thawed embryo transfer(FET)of IVF or ICSI-ET in the Department of Reproductive Medicine,Women and Children's Hospital Affiliated to Xiamen Univer-sity from November 2011 to December2021 were analyzed retrospectively,The propensity score matching(PSM)method(1∶4)was used to include the study subjects.The surgical reduction group and the spontaneous single-ton group were included in 128 cycles and 510 cycles,respectively.The spontaneous reduction group and the ini-tial singleton group were included in 511 cycles and 2038 cycles,respectively.The pregnancy outcomes of each groups were compared.Results:After PSM,the number of transferred embryos in the surgical and spontaneous reduction group was higher than that in the initial singleton group.The gestational week of delivery was earlier than that of the initial singleton group,and the birth weight of the newborn was lower than that in the initial single-ton group.The rate of premature delivery and low birth weight was higher than that in the initial singleton group,and the difference was statistically significant(P<0.05).The incidence of pregnancy complications(postpartum hemorrhage,gestational diabetes,hypertensive disorders of pregnancy)and the rate of cesarean section were not significantly different(P>0.05).The abortion rate and neonatal birth defect rate were missing after adjusting the PSM model.According to the calculation before adjustment,the early abortion rate of the surgical reduction group and the spontaneous reduction group were significantly lower than that in the initial singleton group(P<0.05),and the late abortion rate of the spontaneous reduction group was lower than that in the initial singleton group,the difference was statistically significant(P<0.05).There was no significant difference in the neonatal birth defect rate between the surgical/spontaneous reduction group and the initial singleton group(P>0.05).Conclusions:Patients with multiple pregnancies caused by assisted reproductive technology(ART)may have a relatively poor prognosis in the perinatal period even if the effect of early pregnancy reduction surgery or spontaneous reduction is limited.Reducing the number of embryos transferred cannot completely reverse the pregnancy outcome.Limiting the number of embryos transferred is the fundamental solution to the adverse outcomes of ART assisted pregnancy.

ABSTRACT
Objective:To compare the effects of bubroscopolamine combined with diclofenac on pain relief and recurrence in patients with stone-forming renal colic.Methods:From December 2016 to December 2018, 86 cases of calculus renal colic were selected.According to random number table method, the patients were randomly divided into control group and observation group, with 43 cases in each group.Both two groups were given plenty of antimicrobial agents and static drops of butyl bromide scopolamine treatment, the control group was intramuscularly injected diclofenac sodium, while the observation group was rectally administered diclofenac sodium suppositories.The pain relief of the two groups was observed, and the incidence of adverse reactions and clinical efficacy of the two groups were compared.Results:After 0.5 h of treatment, the total effective rate of pain relief in the control group was 88.37%(38/43), which was significantly higher than 48.84%(21/43) in the observation group (χ 2=8.384, P<0.05). The VAS score of the observation group was (2.62±1.02)points, which was significantly lower than that of the control group[(4.21±0.84)points]( t=4.394, P<0.05). After 1 h of treatment, there were no statistically significant differences in the total effective rate of pain relief and VAS score between the two groups (all P>0.05). The incidence and recurrence rates of adverse reactions in the control group were 18.60%(8/43) and 20.93%(9/43), respectively, which were significantly higher than those in the observation group [4.65%(2/43) and 4.65%(2/43), χ 2=7.394, 8.769, all P<0.05]. There was no statistically significant difference in pain relief between the two groups after secondary treatment (all P>0.05). Conclusion:The analgesic effect of intramuscular injection of diclofenac sodium is significantly faster than rectal administration in patients with stone renal colic, but the adverse reactions of this method are more and the curative effect lasted for a short time.Rectal administration of diclofenac sodium suppository is safe and stable for patients with stone renal colic, so it is worthy of popularizing in clinic.
ABSTRACT
OBJECTIVE To invest igate the correlation between fractional exhaled nitric oxide(FeNO) and lung function in artemisia argyi allergy patients. Whether the course of disease and rhinitis score are correlated with FeNO and lung function. METHODS A total of 88 patients with mugwort pollen allergy, who visited the hospital between August and September 2017 and August and September 2018, the results of their FeNO and Pulmonary ventilation function, were included in this study. RESULTS Compared with patients with a duration of 9 years or more, FeNO and FEV1% of patients with a duration of 5 years were significantly different(P =0.004, P =0.032), and FeNO increased with the extension of the duration, while FEV1% decreased gradually. FeNO was negatively correlated with FEF25%-75%pred and FEV1%, while there was no correlation with FEV1%pred. Rhinitis score was positively correlated with FeNO. There was no correlation with FEV1%pred, FEV1%, FEF25%-75%pred. CONCLUSION With the development of mugwort pollen allergy, the probability of airflow limitation is also increased. To some extent, FeNO can predict the changes of airway function early, and can be used as a monitoring indicator for asthma prediction.FeNO value can reflect the degree of inflammation of the body, and can be used in the auxiliary diagnosis of the severity of allergic rhinitis patients.

ABSTRACT
Objective To compare the evaluation of care behaviors among inpatients and nurses, in order to know the implementation of caring behavior from different perspectives, and to provide evidence for better humanistic care in hospitals. Methods The nurses' humanistic practice ability scale and the caring behavior scale were used to investigate 160 nurses and inpatients respectively in The Third Affiliated Hospital of Southern Medical University. Results The total score of nurses' self rating for caring behavior was (4.15 ± 0.58) points, while the score of self-management ability was lowest, which was (3.84 ± 0.67) points;and the total score of nurses' caring behaviors was (3.49 ± 0.92) points, while the lowest scoring dimensions were respect and connection (3.42 ± 0.95) points. Nurses and patients both feel better at basic care (such as meeting basic needs, providing good environment), psychological care (such as giving support and) and professional care (such as health education), but both of them think that nurses did not do good enough in the provision of high-level emotional needs (such as diversified care, spiritual sustenance)and participation in nursing programmes. Conclusions The evaluation of nursing caring behavior is in the middle and upper level, which shown that the nurses have certain humanistic care and practical ability in clinical practice, and have been recognized by patients, but there is still a lot of room for improvement, and suggested that nursing administrators should give nurses enough respect and consideration while considering patients.

ABSTRACT
Immunosuppression plays a vital role in the pathophysiological mechanism of sepsis, and it is the main cause of death in patients with sepsis during the later phase. Sepsis induced immunosuppression is gradually recognized. Its underlying mechanisms involve immune cell apoptosis, autophagy, cell metabolism reprogramming, endotoxin tolerance, central nervous system regulation, and epigenetic regulation. New approaches that target the host immune response and reconstruct the immune balance are the keys to improve the prognosis of patients with sepsis. With the help of immune status monitor, novel immunomodulatory agents, such as thymosin α1, γ- interferon (IFN-γ), interleukin-7 (IL-7), granulocyte-macrophage colony stimulating factor (GM-CSF) and anti-programmed death receptor 1 (PD-1) antibody, are expected to become a new strategy for the treatment of sepsis in future.

ABSTRACT
Objective To explore the differences in clinical and pathological characteristics of idiopathic membranous nephropathy between elderly and non elderly patients.Methods The clinical and pathological data,which were used for biopsy diagnosing idiopathic membranous nephropathy in elderly patients (aged ≥65 years) versus non elderly patients (aged <65 years) in our hospital during the recently 10 years,were retrospectively analyzed and compared.Results The elderly patients with idiopathic membranous nephropathy accounted for 26.29% and patients aged less than 45 years with idiopathic membranous nephropathy accounted for 25.26%.The proportions of idiopathic membranous nephropathy in the two different age groups were similar.The occurrence rate of hypertension and microscopic hematuria as well as levels of blood serum creatinine and urinary N-acetyl-β-D-glucosaminidase were higher,while the urinary osmotic pressure,estimated glomerular filtration rate (eGFR) and blood albumin were lower in elderly group than in non-elderly group (all P<0.05).The proportions of glomerulosclerosis,tubulointerstitial lesions and vascular lesions were higher in elderly group than in non-elderly patients (all P< 0.05).There were no significant differences in the immunofluorescence intensity of IgG,positive rates of IgA,C3,C4 and Fi between the two groups,while the positive rate of C1q was lower in elderly group than in non elderly.Among 51 patients receiving IgG4 immunohistochemical staining,the positive rate of IgG4 staining and the intensity were higher in elderly group than in non-elderly [100.00% vs.81.25%,(2.11±0.46) vs.(1.59 ± 0.95),both P < 0.05].Conclusions The proportion of idiopathic membranous nephropathy is increased in non-elderly patients.Elderly patients are more susceptible to hypertension,hematuria and renal dysfunction.The positive rate and the intensity of IgG4 are higher and the positive rate of C1q is lower in elderly group than in non-elderly group,which indicate that patients with negative IgG4 and positive C1q have secondary causes which have not yet been demonstrated,and they should be closely observed during the follow-up.
ABSTRACT
Objective To investigate the changes of protein and energy intakes and the z-score of weight for age in appropriate for gestational age (AGA) and small for gestational age (SGA) preterm infants with gestational age less than 34 weeks. Methods The data from 314 hospitalized premature infants ( 268 cases of AGA and 46 cases of SGA) during January 2012 to December 2014 were retrospectively collected. The intakes of protein and energy and the changes of weight within 2 weeks after birth were compared. Results Compared with AGA group, the hospital stays, durations of parenteral and enteral nutrition and total enteral nutrition, and time to achieve full dose feeding were signiifcantly longer in SGA group (P?0 . 05 ). The energy intakes on day 4 , 8 , and 12 after birth in SGA group was obviously lower than in AGA group;the protein intakes on day 6 and 8 in SGA group was also obviously lower than in AGA group (P?0 . 05 ). The daily average weight gain was signiifcantly higher in SGA group than that in AGA group (P?0 . 05 ). The z-score of weight for age was gradually away from the median level in both AGA group and SGA group within 2 weeks after birth. Moreover, the z-score of weight for age at 2 weeks was lower in SGA group than that in AGA group (P?0 . 05 ). Conclusions The growth velocity in SGA premature infants was faster than that in AGA premature infants with gestation age lower than 34 weeks after recovery of birth weight. There was catch-up growth to some extent. However, the growth of SGA and AGA premature infants need to be improved.
