Does serum progesterone level impact the ongoing pregnancy rate in frozen embryo transfer under artificial preparation with vaginal progesterone? Study protocol for a randomized controlled trial.

BACKGROUND: In previous retrospective studies, low serum progesterone level on the embryo transfer day is associated with lower clinical pregnancy and ongoing pregnancy rates. Whether adding progesterone in low serum progesterone patients can rescue the outcome, there is no sufficient evidence from randomized controlled studies. METHODS: This trial is a clinical randomized controlled study (high serum progesterone vs low serum progesterone 1:1, 1:1 randomization ratio of intervention vs the control group with low serum progesterone). The eligible hormone replacement therapy-frozen embryo transfer (HRT-FET) cycles, will be recruited and randomly assigned to two parallel groups when serum progesterone is < 7.24µg/l on the day of embryo transfer for D3. The intervention group will be extrally given intramuscular progesterone 40 mg per day from D3 to 8 weeks of gestation if clinical pregnancy. The primary outcome is the ongoing pregnancy (beyond 12 weeks of gestation) rate. DISCUSSION: The findings of this study will provide strong evidence for whether the progesterone addition from the D3 in low serum progesterone patients can improve the outcome in the HRT-FET cycle.

Physicochemical properties and cytocompatibility of biomimetically precipitated nanocrystalline calcium phosphate granules / 中国组织工程研究

BACKGROUND:Artificially synthesized hydroxyapatite ceramic granules are widely used in clinical practice to repair large-volume bone defects.However,the osteogenic effect of hydroxyapatite ceramic granules prepared by high-temperature sintering is limited by their low degradability and bioactivity. OBJECTIVE:To prepare biomimetically precipitated nanocrystalline calcium phosphate granules by a novel low-temperature deposition technique,and to characterize their physicochemical properties and cytocompatibility. METHODS:Biomimetically precipitated nanocrystalline calcium phosphate granules were prepared using a modified supersaturated calcium phosphate mineralization solution and a repeated settling and decantation washing method.Hydroxyapatite bioceramic granules were used as the control.The morphology and phase composition of the granules were characterized by scanning electron microscopy,X-ray diffraction,and Fourier transform infrared spectroscopy.The specific surface area,porosity distribution,hardness and hydrophilicity of the granules were characterized by BET-N2 method,hardness test,and contact angle test.The adsorption properties of the granules for bovine serum albumin and fetal bovine serum protein were determined by bicinchoninic acid assay.The two kinds of granules or granule extracts were co-cultured with human umbilical cord mesenchymal stem cells,and the cell proliferation was detected by MTT assay. RESULTS AND CONCLUSION:(1)Scanning electron microscopy showed that the surface of the two kinds of particles was slightly rough and accompanied by tiny particles,the surface of the hydroxyapatite bioceramic particles was dense and smooth,and the biomimetically precipitated nanocrystalline calcium phosphate granules were mainly composed of needle/plate crystals with non-uniform nanometer size,and formed a nanopore structure between the crystals.X-ray diffraction and Fourier transform infrared spectroscopy exhibited that compared with hydroxyapatite bioceramic granules,biomimetically precipitated nanocrystalline calcium phosphate granules had smaller crystalline particles,lower crystallinity,and more binding water and carbonic acid groups.Compared with hydroxyapatite bioceramic granules,biomimetically precipitated nanocrystalline calcium phosphate granules had higher specific surface area,better hydrophilicity,lower hardness,and higher protein adsorption capacity.(2)The results of MTT assay showed that the two kinds of granule extracts had no cytotoxicity,human umbilical cord mesenchymal stem cells survived well on the surface of the two kinds of granules,and the biomimetically precipitated nanocrystalline calcium phosphate granules had stronger cell proliferation activity.(3)These findings indicate that compared with hydroxyapatite bioceramic granules,biomimetically precipitated nanocrystalline calcium phosphate granules have better physicochemical properties and cytocompatibility.

Effects of preoperative dezocine patient-controlled analgesia pump on stress response and cognitive function in elderly patients with lower extremity fractures / 中国临床药理学与治疗学

AIM: To explore the effects of preoperative application of dezocine patient-controlled analgesia pump on stress response and cognitive function in elderly patients with lower extremity fractures. METHODS: A total of 80 elderly patients with lower extremity fractures who were treated from November 2018 to June 2020 were selected and randomly divided into a control group and a study group, 40 cases in each. The control group was not given a patient-controlled analgesia pump before anesthesia, and the study group was given intravenous analgesia with a dezocine patient-controlled analgesia pump before surgery. The postoperative stress response, cognitive function and safety were compared between the two groups.RESULTS: There were no significant differences in cognitive function MMSE score, stress response index (cortisol, epinephrine) levels, and inflammatory factors (IL-6, TNF-α) levels between the two groups before intervention (P>0.05). Compared with the indexes after operation, the MMSE scores of the study group at 12 h, 24 h and 3 days after operation were higher than those in the control group (P<0.05); The levels of cortisol, epinephrine, IL-6 and TNF-α in the study group were lower than those in the control group at 12 h and 24 h after operation (P<0.05); At the same time, the incidences of respiratory depression, urinary retention and nausea and vomiting in the study group were significantly lower than those in the control group (P<0.05).CONCLUSION: Preoperative application of dezocine patient-controlled analgesia pump in elderly patients with lower extremity fracture can significantly reduce postoperative stress response, reduce inflammatory response, and improve postoperative cognitive function, which is worthy of clinical application.

Expectations and their influencing factors of gynecological examination among female physical examination population / 中华健康管理学杂志

Objective:To analyze the expectations and their influencing factors of gynecological examination among female physical examination population.Methods:Convenience sampling method was used to select women undergoing gynecological examinations in the health management center of the Shandong Provincial Hospital Affiliated to Shandong First Medical University between April to June 2021. A face to face interview was conducted with a 20-item structured questionnaire including general information, the women?s feelings about a gynecological examination, expectations of doctors, preferences for the doctor ?s gender, and the presence of chaperones in male doctor examination scenarios. Of the 1 600 questionnaires distributed, 1 583 were valid, with a recovery rate of 98.93%. To compare the preferences for a doctor ?s gender and chaperones with different demographic characteristics, an χ2 test was used. Logistic regression was used to analyze the influencing factors of preferences for doctors ?gender and for chaperones. Results:For a gynecological examination, women were mainly worried about the possibility of bad results (77.4%), while the main expectation to doctors was communication before the examination (49.2%); most women wanted to be examined by a female doctor (85.5%), mainly because they felt relaxed (76.0%); most women did not want chaperones when examined by a female doctor (56.5%), while most of them preferred to be accompanied by a nurse when examined by a male doctor (50.1%). Women whose family income was lower than expenditure and had gynecological examination experiences with male doctors tended to have no preference for a doctor ?s gender. Additionally, there was a strong inverse association between the education level and likelihood of no preference for a doctor ?s gender, that is, the lower the education level, the more likely they were to have no preference for the doctor ?s gender ( P<0.05), when examined by a male doctor. Furthermore, women older than 55 years and who had a gynecological examination more than twice a year, was less likely to need chaperones, while women who had gynecological examination experience with male doctors tended to have no preference for chaperones. Conclusions:Women preferred gynecological examinations to be performed by female doctors who provide gentle and companion staff support during the examinations. Education level, family income, and examination experience of male doctors are the influencing factors for gender preferences of a doctor. Age, examination frequency, and examination experience of male doctors are the influencing factors affecting the preferences of choosing an accompanying person.

Functional electrical stimulation can improve the gait of hemiplegic stroke survivors with an ankle-foot orthosis / 中华物理医学与康复杂志

Objective:To observe the effect of functional electrical stimulation (FES) combined with an ankle-foot orthosis (AFO) and gait training on lower limb motor function, gait parameters and the joint angles of hemiplegic stroke survivors.Methods:Thirty-two stroke survivors who met the inclusion criteria were selected and randomly divided into a control group ( n=10), an orthosis group ( n=10), and a combination therapy group ( n=12). In addition to routine medication and rehabilitation, the control group received only gait training, the orthosis group received gait training and an AFO and the combination therapy group was given FES, an AFO and gait training. All three groups were treated for four weeks. Then, the Fugl-Meyer lower extremity assessment (FMA-LE), the Brunnstrom lower extremity assessment (BRL), and Functional Ambulation Categories (FACs) were used to evaluate the lower limb motor function and walking ability of the three groups. The gait parameters of the three groups were quantified using a three-dimensional gait analyzer, and the changes in the hemiplegic gait before and after treatment were compared among the three groups. Results:After the treatment the average FMA-LE, FAC and BRL scores, time-space parameters, and joint angle parameters of all three groups had all improved significantly. After the intervention the average indicators in the combined therapy group (including stride frequency, stride length and walking speed) were all significantly better than in the other two groups.Conclusions:Adding FES to gait training with an AFO can effectively improve lower limb motor function and the walking ability of hemiplegic stroke survivors.

Risk of low birth weight infants in women conceived through in vitro fertilization and fresh embryo transfer / 中华围产医学杂志

Objective To analyze the risk factors of low birth weight (LBW) in infants who were conceived through flesh embryo transfer after in vitro fertilization.Methods We retrospectively reviewed the medical records of 4 930 live babies born after in vitro fertilization/intra-cytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) at Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University between January 2011 to December 2016.They were 3 474 singletons and 1 456 pairs of dizygotic twins.According to their birth weight,all singletons were divided into two groups:the LBW singleton group (＜2 500 g,n=252) and the control singleton group (≥ 2 500 g,n=3 222).Two dizygotic twin groups,the LBW dizygotic twin group (＜2 500 g,n=1 014) and the control dizygntic twin group (≥ 2 500 g,n=442),were set up as well.Clinical characteristics of the infants in different groups and risk factors of LBW were analyzed.Independent samples t-test,Mann-Whitney U test,Chi-square test,and logistic regression were used for statistical analysis.Results (1) The rates of LBW were 7.25％ (252/3 474) in singletons and 69.64％ (1 014/1 456) in dizygotic twins.(2) In singleton pregnancies,the maternal body mass index (BMI) of the LBW group was lower than that of the control group [(20.9± 2.8) vs (21.3 ± 2.7) kg/m2,t=-2.162,P=0.031],while the rates of preterm delivery and blastocyst transfer were higher [61.7％ (153/252) vs 5.7％ (182/3 222),8.7％ (22/252) vs 5.1％ (163/3 222),x2=814.232 and 6.234,respectively,all P＜0.05].(3) In dizygotic twin pregnancies,maternal age,paternal age,the rate of preterm delivery and estradiol (E2) level [M(P25-P75)] at trigger were higher than those of the control group [(31.0±3.7)vs (30.5±3.9) years,(33.7±5.0) vs (32.7±4.5) years,63.0％ (631/1 014) vs 28.0％ (123/442),11 362.3 (7 549.2-16 716.1) vs 10 444.8(7 079.4-14 569.9) pmol/L;the values of t or x2 or Z were-2.498,-3.680,150.295 and-2.570,all P＜0.05].(4) Multivariate logistic regression analysis revealed that preterm delivery,maternal BMI＜18.5 kg/m2 and girl baby were independent risk factors for LBW in singleton pregnancies (adjusted OR=28.45,1.59 and 1.45,95％CI:20.87-38.80,1.06-2.41 and 1.06-1.97,all P＜0.05).Preterm delivery,high E2 level at trigger (＞10 970 pmol/L) and different gender of twins were independent risk factors for LBW in dizygotic twin pregnancies (adjusted OR=4.51,1.35 and 1.45,95％CI:3.50-5.82,1.06-1.74 and 1.09-1.93,all P＜0.05).Conclusions High maternal serum E2 level after controlled ovarian stimulation (COS) in fresh embryo transfer cycle may be one of the risk factors for LBW in twin pregnancies.

Objective@#To compare the clinical outcomes of posterior maxillary implant surgery when using the regular transalveolar approach or with the crestal approach-sinus (CAS-KIT), a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure.@*Methods@#In this retrospective study 887 patients during Jan 2012 to July 2015 in Hangzhou Dental Hospital with underwent either regular transalveolar approach or CAS-KIT approach for maxillary augmentation; whereas 11 patients dropped out for the reason of serious membrane perforations. Totally, 876 patients with 1 204 plants, placed immediately after transalveolar maxillary augmentation, were included in this study. The data analysis was performed by radiological measures to assess the changes in height of maxillary sinus floor after the transalveolar augmentation at different time points. In addition, the complications after surgery, failure rates, osseointegration condition and the performance of rehabilitation were evaluated as well.@*Results@#Five hundred and three patients were experienced with regular transalveolar approach, and 7 patients were drop out for the serious membrane perforations. Thus, 496 patients received 653 implants in this group; the average lifted range in maxillary sinus floor height changes was (4.08±3.45) mm. The complications were minor membrane perforations during procedure in 64 patients, postoperative maxillary sinus infection happening in 2 patients and 13 patients experienced rehabilitation failure. Three hundred and eighty-four patients had CAS-KIT approach with 4 patients dropped out. Three hundred and eighty patients get 551 implants with the mean lifted range of (8.36±4.07) mm in maxillary sinus floor height changes. Minor membrane perforations during procedure occurred in 31 people and 2 got postoperative maxillary sinus infection. The 4 year overall survival rate of 1 204 implants was 97.26%, with four implants fell off after 3 months of rehabilitation and one implant occurred after one year of rehabilitation.@*Conclusions@#The regular transalveolar sinus lift technique is easier and time saving, but the compromised lifting range in maxillary sinus floor height and the comparatively high occurrence of intraoperative membrane perforations should be concerned. Using CAS-KIT could be an alternative method to perform maxillary sinus augmentation with a reduced incidence of complications. There was no statistically difference in implant failure rates and incidence of postoperative maxillary sinus infection between two groups.

Role and mechanism of retinoic acid in axonal regeneration / 中国组织工程研究

BACKGROUND:Retinoic acid signaling pathways is very important in the formation pf nervous system, specialization of neurons and outgrowth of axons. The recent studies show that, retinoic acid plays an important role in the process of axonal regeneration, but few research reports its exact molecular mechanism. OBJECTIVE:To analyze and summarize the mechanism underlying retinoic acid signaling pathways in the process of axonal regeneration. METHODS:A computer-based online research was conducted among the VIP, CNKI, PubMed, BioMed Centeral, Springer, The Free Medical Journals, EBSCO and Foreign Journals Integration System between January 2000 and December 2013, with the key words of“retinoic acid, the central nervous system, nerve damage, axon regeneration, and mechanism”in Chinese and English. A total of 43 studies addressing the molecular mechanism of retinoic acid in axonal regeneration were screened. According to the supplementary documents, another five references were added. Repetitive research and atypical reports were excluded. RESULTS AND CONCLUSION:Fol owing acute central nervous system injury, axonal regeneration and functional recovery are extremely limited. For proper functionality fol owing injury, axons must regrow, reinnervate their targets, and remyelinate their axons. When the central nervous system injuries occur, retinoic acid signaling pathways express transcription factor retinoic acid receptorβ2 to induce axonal regeneration fol owing injury;in dorsal root ganglion neurons, cAMP levels are greatly increased by lentiviral retinoic acid receptorβ2 expression and contribute to neurite outgrowth. More recently, retinoic acid-retinoic acid receptorβ2 pathways directly transcriptional y repress a member of the inhibitory Nogo receptor complex, Lingo-1, under an axonal growth inhibitory environment in vitro as wel as fol owing spinal cord injury in vivo. Through these molecular mechanisms, retinoic acid signaling pathways play its important role in the process of axonal regeneration.
