Spontaneous rupture of extensor pollicis longus after distal radius fracture: a case report

Extensor pollicis longus tendon rupture, rare and linked to trauma or arthritis, is prevalent post-distal radius fractures. Mechanisms include friction and vascular issues. Manifestations occur 4-8 weeks’ post-trauma. We present the case of A 31-year-old male, post-motorcycle accident surgery for distal radius fracture, faced extensor pollicis longus tendon rupture. A surgical intervention transposed the extensor indicis proprius tendon, restoring thumb function. Successful closure and splinting showed no movement limitations at the 12-week follow-up, prompting a rehabilitation referral. Distal radius fracture treatments, whether operative or non-operative, entail risks of extensor tendon complications, notably extensor pollicis longus. While direct suture repair is optimal, studies endorse effective restoration of thumb function through tendon grafts, particularly utilizing the extensor indicis proprius. Rupture of the extensor pollicis longus, while uncommon, often occurs with distal radius fractures. Extensor indicis proprius grafting is recommended for superior efficacy over alternatives, emphasizing the need for accurate and timely diagnosis.

Identification of Spices and their Adulterants by Integrating Machine Learning and Analytical Techniques: A Representative Study

This multidisciplinary research presents a comprehensive method to tackle the widespread problem of spice adulteration, which represents substantial risks to both public health and spices authenticity. A comprehensive approach is developed to authenticate spices with high accuracy and efficiency by combining old methods with contemporary approaches such as machine learning and artificial intelligence. This paper presents a specific case study where machine learning models, specifically using transfer learning with proven frameworks like MobileNetV2, were effectively employed. The models achieved an impressive accuracy of 98.67% in identifying Capsicum annum, a spice that is usually adulterated in the market. In addition, a wide range of traditional and advanced techniques, including qualitative testing, microscopy, colorimetry, density measurement, and spectroscopy, are reviewed closely. In addition, this article provides a detailed explanation of high-performance liquid chromatography based quantitation of capsaicin, which is the main active constituent for ascertaining the quality of C. annum. The present work defines a new interdisciplinary approach and also provides valuable information on evaluating the quality of spices and identifying adulterants using artificial intelligence. The outcomes presented here have the potential to completely transform the methods used to verify the authenticity of spices and herbal drugs, therefore ensuring the safety and health of consumers by confirming the quality.

Staged Treatment with Chinese Herbal Medicine in a Controlled Ovarian Hyperstimulation of In Vitro Fertilization-Embryo Transfer Programme / 中医杂志

It is believed that kidney deficiency is the fundamental pathogenesis while liver constraint and spleen deficiency， and disharmony of chong （thorough vessel， 冲脉）and ren （conception vessel， 任脉） is the key pathogenesis of infertility patients who adopted controlled ovarian hyperstimulation of in vitro fertilization-embryo transfer （IVF-ET） programme. Therefore， the method of tonifying the kidneys dominantly and treating the liver and spleen simultaneously is proposed， and Chinese herbal medicine is suggested to be used in adjuvant treatment of staged IVF-ET controlled ovrian hyperstimulation. In the regulation stage， modified Liuwei Dihuang Pill （六味地黄丸） can be used to tonify kidney and supplement essence， fortify spleen and nourish liver； in the ovulation promotion stage， modified Wenjing Decoction （温经汤） should be used to warm kidney and assist yang， dispel stasis and nourish blood； in the pre-transplantation endothelial preparation stage， modified Shenling Baizhu Powder （参苓白术散） is suggested to fortify spleen and replenish qi， invigorate blood and resolve stasis； after the transplantation stage， modified Shoutai Pill （寿胎丸） or Taiyuan Decoction （胎元饮） can be taken to fortify spleen and tonify kidney， benefit qi and nourish blood.

Comprehensive analysis of insulin products complex disulfide bonds structure by high resolution mass spectrum / 药学学报

The correct pairing of disulfide bonds maintains the correct folding mode and high-level structure formation of peptides and protein drugs, which is crucial for the quality control of products. In order to ensure that the disulfide bonds are correctly paired, disulfide bond analysis is an essential part of peptides and protein drug characterization. Mass spectrometry can be used to analyze disulfide bonds. However, insulin and its analogues have two pairs of disulfide bonds without restriction enzyme cutting site. Conventional collision-induced dissociation (CID) and high-energy induced cleavage (HCD) cannot accurately locate the complex disulfide bond. In our study, three methods were used to localize the complex disulfide, including enzyme digestion combined with key peptide fragment in source decay (ISD) fragmentation method, enzyme digestion combined with partial reduction alkylation method, intact protein source ISD and electron transfer dissociation (ETD) cleavage method, The applicability of insulin aspart, insulin lispro and insulin glargine were also investigated. This study provides a new way for the quality control of disulfide bonding mode of insulin and its analogues, and also provides a reference for the disulfide bond localization of peptides or proteins containing this complex disulfide bond.

Predictive value of combination of normal morphology sperm percentage and sperm DNA fragmentation index for in vitro fer-tilization embryo transfer outcomes / 临床检验杂志

Objective To investigate the effects of combined assessment of normal morphology sperm rate(MNS)with sperm DNA fragmentation index(DFI)on the outcomes of in vitro fertilization-embryo transfer(IVF-ET).Methods A retrospective analysis was conducted on the clinical data of 641 patients who underwent IVF-ET in our center from June 2020 to February 2023.According to MNS and DFI levels,the patients were divided into group A(MNS＜4％,DFI＜25％,403 cases),group B(MNS ≥4％,DFI ≥25％,9 ca-ses),group C(MNS≥4％,DFI＜25％,125 cases),group D(MNS＜4％,DFI≥25％,104 cases),group A1(MNS＜1％,DFI＜25％,106 cases)and group D1(MNS＜1％,DFI≥25％,60 cases).The general information,semen parameters,embryo develop-ment and pregnancy outcomes were compared among all the 6 groups.Results No statistically significant differences were found be-tween female and male age among these groups(P＞0.05).Significant differences were observed in sperm motility,progressive motili-ty,sperm concentration and fertilization rates(P＜0.05),but no differences of usable embryo rates,good-quality embryo rates,clinical pregnancy rates,early miscarriage rates,or live birth rates(P＞0.05)among the groups A,B,C,D,A1 and D1.Conclusion The decreased MNS and increased DFI in males were associated with reduced sperm motility and concentration,affecting fertilization rates in IVF-ET,but had no significant impact on clinical pregnancy outcomes.The combined assessment of MNS with DFI had limited pre-dictive value for IVF-ET pregnancy outcomes.

Analysis of Cumulative Live Birth Rate of Selective Single Embryo Transfer by Time-lapse Monitoring System and Conventional Morphological Assessment in IVF/ICSI-ET / 实用妇产科杂志

Objective:To analyse the clinical significance of selective single embryo transfer by time-lapse mo-nitoring(TLM)or conventional morphology assessment(CMA)in vitro fertilization/intracytoplasmic sperm in-jection and embryo transfer(IVF/ICSI-ET),and to initially explore the predictive value of Raman spectral analy-sis of embryo culture medium for clinical pregnancy rate.Methods:The study is a prospective randomized con-trolled clinical trial.We assigned 139 patients treated with IVF/ICSI-ET in Reproductive and Genetics Center of Suzhou Municipal Hospital from April 2019 to July 2020,which were randomly assigned to either the CMA or the TLM group.We performed selective single-embryo transfer(fresh cycle and FET)after selecting the optimal em-bryos with TLM or CMA respectively.If the patient's first embryo transfer was unsuccessful,a second one would be performed to compare the differences in the cumulative live birth rate of embryo transfer and other pregnancy outcomes between the two groups.Meanwhile,we collected 15 μl of embryo culture medium at day 3 after IVF/ISCI fertilization for Raman spectroscopy analysis.Results:There were no differences in cumulative live birth,cu-mulative clinical pregnancy,cumulative premature birth,cumulative early spontaneous abortion,cumulative ectopic pregnancy and LGA or SGA between TLM and CMA groups(P＞0.05).The Neonatal sex ratio in the TLM group was lower than that in the CMA group,but the difference was not significant(P＞0.05).Raman spectros-copy analysis of embryo culture medium predicted the clinical pregnancy rate with 67.21％accuracy.Conclu-sions:In young women with a good ovarian reserve,the advantage of using TLM to evaluate embryos is not obvi-ous,so we should remain vigilant that embryo selection based on morphokinetic parameters may affect the sex ratio.Raman spectroscopic analysis of embryo culture medium is not yet able to effectively predict the planting ability of embryos.

Trajectories and influencing factors of post-traumatic stress disorder in women with multiple in vitro fertilization embryo transfer failures / 中国实用护理杂志

Objective:To explore the potential categories of post-traumatic stress disorder (PTSD) trajectories in women with multiple in vitro fertilization-embryo transfer (IVF-ET) failures, and to analyze the effects of different demographic characteristics and psychological factors on the potential categories of PTSD trajectories.Methods:This was a prospective empirical research, from May 2021 to October 2022, women with IVF-ET failure ≥ 2 times in the reproductive department of Shanghai First People′s Hospital from May 2021 to October 2022 were selected as the research objects. Post-traumatic stress disorder civilian version scale was used for 4 follow-ups at 3 d (T1), 10 d (T2), 20 d (T3) after the last transplantation failure and 3 d before the next transplantation cycle (T4). Telephone follow-up and online follow-up were combined to obtain the PTSD level at 4 time points. Potential categories of PTSD score trajectories at four time points were identified using a latent category growth model, and analyze influencing factors using unordered multi classification logistic analysis.Results:Totally 196 IVF-ET women were admitted, aged (29.42 ± 4.13) years. Three PTSD trajectories were fitted in this study, including 82 cases (42%) in non-PTSD group, 61 cases (31%) in mild PTSD group and 53 cases (27%) in elevated PTSD group. Logistic regression analysis showed that age, education level, fertility pressure and marital adjustment level were the predictors of PTSD trajectory in women with multiple IVF-ET failures. Compared with the non-PTSD group, women aged ≥35 years, with lower education level and marital adjustment level were more likely to enter the elevated PTSD group ( OR=4.570, 8.540, 0.949, all P<0.05). Women aged 35 years and with greater reproductive pressure were more likely to enter the mild PTSD group ( OR=3.871, 1.063, both P<0.05). Conclusions:There is group heterogeneity in the trajectories of PTSD in women with multiple IVF-ET failures in the next transplantation cycle. Old age, low education level, high fertility pressure and poor marital adjustment can predict the trajectories of PTSD. Fertility stress and marriage adjustment are changeable variables. Medical staff can relieve women′s fertility pressure through health education and mindfulness intervention, promote a good state of marriage adjustment, and minimize the adverse effects of PTSD on the next cycle of conception.

A study on the relationship between irrational fertility cognition and reproductive life quality of in vitro fertilization-embryo transfer female patients: the mediating effect of psychological resilience / 中国实用护理杂志

Objective:To investigate the relationship between psychologicalresilience and irrational parenthood cognition and fertility life quality in female patients with in vitro fertilization-embryo transfer, and to analyze the mediating effect of psychological resilience on irrational parenthood cognition and fertility life quality, so as to provide guidance for infertility patients to improve their psychological resilience and fertility life quality.Methods:A cross-sectional study method was used to conveniently sample 460 female patients with in vitro fertilization-embryo transfer who were admitted to the Women′s Hospital, School of Medicine Zhejiang University from October 2022 to April 2023.General data questionnaire, Connor-Davidson Resilience Scale, Irrational Parenthood Cognitions Questionnaire and the Fertility Quality of Life were used for investigation.Results:A total of 449 valid questionnaires were retrieved. Patients aged (33.31 ± 4.99) years old. The total scores of irrational parenthood cognition, psychological resilience and the fertility quality of life were (38.73 ± 9.31), (63.19 ± 15.40) and (68.18 ± 11.89) points respectively for female patients with IVF-ET. The total score of irrational parenthood cognition was negatively correlated with the total score of fertility quality of life ( r = - 0.513, P<0.01), and the total score of psychological resilience was positively correlated with the total score of fertility quality of life ( r = 0.424, P<0.01). Pychological resilience played a partial mediating role between irrational parenthood cognition and fertility life quality, with the mediating effect accounting for 28.01% of the total effect. Conclusions:The irrational parenthood cognition of female patients with IVF-ET is at a medium level, and the psychological resilience and the fertility quality of life are at a low level. The irrational parenthood cognition has a direct negative predictive effect on the fertility life quality of patients, while the psychological resilience is a positive predictor of fertility life quality. Irrational parenthood cognition can directly or indirectly affect patients′ fertility life quality through psychological resilience.

Objective To investigate the role of complement C3 in early predicting pregnancy outcomes of frozen-thawed embryo transfer(F-ET).Methods A total of 378 F-ET cycles were prospectively collected and divided into group A(complement C3≤1.05,120 cycles)and group B(complement C3>1.05,258 cycles)based on the best cutoff value of complement C3 for predicting F-ET pregnancy outcomes.The outcomes of the two groups were compared,and the best cutoff value of complement C3 for predicting F-ET spontaneous abortion was analyzed in group B.Results Age was a risk factor for successful F-ET pregnancy(P<0.05),and complement C3 and embryo type were protective factors for successful F-ET pregnancy(P<0.05).The area under the receiver-operating characteristic curve(ROC)of complement C3 for predicting F-ET pregnancy outcome was 0.702,and the best cutoff value was 1.05 g/L,with a clinical pregnancy sensitivity of 87.60%and a specificity of 52.00%.The clinical pregnancy rate and embryo implantation rate in group B were both significantly higher than those in group A(67.05%vs.52.75%,P<0.05).The best cutoff value of complement C3 for predicting spontaneous abortion after F-ET was 1.32 g/L,with an area under the ROC curve of 0.760,a sensitivity of 69.00%,and a specificity of 81.20%.Conclusions Complement C3 is of significance in the early prediction of F-ET pregnancy outcome.When complement C3 exceeds the level of 1.32 g/L,it may lead to an increase in the rate of spontaneous abortion.

Effect of Zishen-Yutai pills on refrozen-thawed embryo transfer in patients with diminished ovarian reserve / 中国组织工程研究

BACKGROUND:Currently,hormone replacement therapy is the main treatment in Western medicine for patients with decreased ovarian function,but these patients are not sensitive to exogenous hormones,leading to unsatisfactory therapeutic effect.Zishen-Yutai pills can nourish the blood and calm the fetus,tonify the kidney and spleen,invigorate qi and strengthen the body.Studies have confirmed that Zishen-Yutai pill is effective in reducing follicle-stimulating hormone index and improving traditional Chinese medicine symptoms in patients with diminished ovarian reserve.However,few studies have been conducted to improve the implantation rate of patients by improving endometrial receptivity. OBJECTIVE:To evaluate the effect of Zishen-Yutai pills on the clinical outcome of patients with diminished ovarian reserve undergoing frozen-thawed embryo transfer again. METHODS:A total of 300 patients with diminished ovarian reserve who underwent frozen-thawed embryo transfer to assist pregnancy after the first failure in the Center of Reproductive Medicine,Changzhou Maternal and Child Health Care Hospital from January 2019 to December 2021 were selected as the study subjects.Subjects were randomly treated with a placebo or Zishen-Yutai pills in a ratio of 1:2,with 100 cases in the treatment group and 200 cases in the control group.However,13 patients fell off due to lack of contact,refusal to take medicine or other reasons.Finally,90 cases in the treatment group and 197 cases in the control group were included in the study.Oral medication was administered 7 days before frozen-thawed embryo transfer transplantation at a dose of 5 g/time,3 times/day.To investigate whether taking Zishen-Yutai pills could improve the clinical outcome of patients with diminished ovarian reserve after frozen-thawed embryo transfer again,the primary outcome measures included clinical pregnancy rate,implantation rate,abortion rate,live birth rate,offspring birth weight and birth defects. RESULTS AND CONCLUSION:Compared with the control group,the clinical pregnancy rate(P<0.05)and implantation rate(P=0.009)were significantly increased after the oral administration of Zishen-Yutai pills.Correlation analysis showed that taking the Zishen-Yutai pill was positively correlated with the number of implanted embryos(r=0.200,P=0.001)and clinical pregnancy(r=0.235,P=0.000).There was no correlation between taking Zishen-Yutai pills and indexes of endometrial thickness and blood flow.It is indicated that Zishen-Yutai pills can improve the clinical pregnancy rate and implantation rate of frozen-thawed embryo transfer recurrence in patients with diminished ovarian reserve.

Strength of association between follicular fluid melatonin levels and pregnancy rates in single-cycle in vitro fertilization-embryo transfer women / 中国组织工程研究

BACKGROUND:In vitro fertilization-embryo transfer is commonly used to solve infertility,but its success rate is not high,the more common reasons are poor endometrial receptivity,poor egg quality,etc.The follicular fluid melatonin can inhibit the aging of the ovary,to a certain extent,can promote the development of embryos,improve the probability of conception,but whether there is a correlation between the two is not known. OBJECTIVE:To explore the correlation between follicular fluid melatonin level and pregnancy rate of single-cycle in vitro fertilization-embryo transfer women. METHODS:A total of 112 female patients who received in vitro fertilization-embryo transfer treatment in the First Affiliated Hospital of Anhui Medical University from December 2020 to April 2021 were selected as the study subjects.They were divided into quartile array(Q1-Q5)according to the follicular fluid melatonin level from low to high.Among them,the melatonin level of group Q1 was<6.99 ng/L(n=18),that of group Q2 was 7.00-9.99 ng/L(n=26),that of group Q3 was 10.00-11.99 ng/L(n=27),and that of group Q4 was 12.00-13.99 ng/L(n=18);and melatonin levels in group Q5 were 14.00-19.99 ng/L(n=23).Clinical data characteristics of the five groups were compared.Multi-factor Logistic regression was used to analyze the correlation between follicular fluid melatonin level and pregnancy rate of women with single-cycle in vitro fertilization-embryo transfer and embryo transfer.A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship,and the model was evaluated by clinical decision curve. RESULTS AND CONCLUSION:(1)Compared with the study population with the lowest melatonin quintile(Q1),with the increase of melatonin level(Q2-Q5),the levels of egg harvest and pregnancy success were gradually increased,and the body mass index was gradually decreased,and the differences were significant(P<0.05).(2)Multivariate Logistic regression analysis showed that after adjusting for confounding factors such as global mass index,number of eggs retrieved,luteinizing hormone,estradiol,progesterone and other confounding factors,follicular fluid melatonin level was still independently correlated with pregnancy rate of single-cycle in vitro fertilization-embryo transfer women(OR=1.538,95%CI:1.032-1.837,P<0.05),and there was significant difference in trend test of follicular fluid melatonin level from low to high quintile array(Ptrend<0.05).(3)The sensitivity test analysis showed that E value was 2.117.Subgroup analysis showed that the study population with higher levels of luteinizing hormone in follicular fluid had a more significant association between follicular fluid melatonin and pregnancy rate in single-cycle in vitro fertilization-embryo transfer women(P interaction=0.008).(4)The results of restricted cubic spline model analysis showed that there was a nonlinear dose-response relationship between follicular fluid melatonin level and pregnancy rate of single-cycle in vitro fertilization-embryo transfer women(P<0.05),and there was an overall positive correlation between follicular fluid melatonin level and pregnancy rate of single-cycle in vitro fertilization-embryo transfer women.(5)The results of clinical decision curve analysis showed that the follicular fluid melatonin level had important clinical value in predicting the pregnancy rate of single-cycle in vitro fertilization-embryo transfer women.(6)Follicular fluid melatonin level is closely related to the pregnancy rate of single-cycle in vitro fertilization-embryo transfer women,and with the decrease of follicular fluid melatonin level,the pregnancy rate of single-cycle in vitro fertilization-embryo transfer women also decreases.
