Objective:To investigate the impact of different luteal phase support protocols on pregnancy outcomes in patients aged ≤35 years undergoing modified natural cycle frozen-thawed embryo transfer (mNC-FET).Methods:A retrospective cohort study was conducted to analyze 2 086 cycles of patients aged ≤35 years who received mNC-FET cycles in Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University from January 2018 to December 2020. The cycles were divided into three groups based on luteal phase support protocols used. The patients received a combination of progesterone soft capsule and dydrogesterone in the group A (446 cycles), the patients received dydrogesterone in the group B (439 cycles), and the patients received a combination of progesterone vaginal sustained-release gel and dydrogesterone in the group C (1 201 cycles). The pregnancy and perinatal outcomes were compared between groups A and B, groups C and B after matching the baseline data in a ratio of 1∶1 using the propensity score matching (PSM). The effect of different luteal phase support on live birth rate was analyzed after adjusting for confounding factors affected by univariate and multivariate generalized estimating equation (GEE).Results:After PSM, there were no significant differences between groups A and B, groups C and B in human chorionic gonadotropin positive rate, clinical pregnancy rate, ectopic pregnancy rate, live birth rate in transplant cycle, incidence of low weight, macrosomia, premature delivery rate, pregnancy complication rate and incidence of birth defects (all P>0.05). GEE analysis showed that three different luteal phase support regimens were not associated with live birth rate. Conclusion:In the mNC-FET cycle, patients aged ≤35 years who chose dydrogesterone alone as luteal phase support drug, had no difference in live birth rate and perinatal outcome between progesterone soft capsules or progesterone vaginal sustained-release gel combined with dydrogesterone, but the outcome still needs to be confirmed by large sample prospective studies.

Objective:To investigate the pregnancy outcomes in patients ≤35 years old with diminished ovarian reserve (DOR) undergoing intrauterine insemination (IUI).Methods:A retrospective cohort study was conducted by analyzing the clinical data of 6 229 IUI cycles performed in patients aged ≤35 years at the Reproductive Health Hospital of the Third Affiliated Hospital of Zhengzhou University between June 2016 and March 2024. Based on serum anti-Müllerian hormone (AMH) levels, the subjects were divided into two groups: patients with AMH <1.1 μg/L were classified as the DOR group (489 cycles), and patients with AMH ≥1.1 μg/L were classified as the normal ovarian reserve (NOR) group (5 740 cycles). Propensity score matching (PSM) was applied to control for confounding factors, after 1∶1 PSM matching, 486 cycles were included in each group. Clinical pregnancy rate, miscarriage rate, live birth rate, biochemical pregnancy rate, and ectopic pregnancy rate were compared between the two groups by generalized estimating equations.Results:The clinical pregnancy rate was 21.19% (103/486) in DOR group and 24.07% (117/486) in NOR group, with no statistically significant difference ( P=0.294). The live birth rate was 18.31% (89/486) in DOR group and 20.16% (98/486) in NOR group, also without significant difference ( P=0.469). Additionally, no significant differences were observed in miscarriage rate, biochemical pregnancy rate, or ectopic pregnancy rate between the two groups (all P>0.05). Conclusion:In patients aged ≤35 years with DOR, pregnancy outcomes from IUI are comparable to those in young patients with NOR.

Objective:To explore the real-life experiences of patients six months after laparoscopic sleeve gastrectomy (LSG), aiming to provide a reference for developing intervention plans.Methods:This was a descriptive phenomenological study. Purposeful sampling and maximum variation sampling were used to select 24 patients who underwent LSG at the Affiliated Hospital of Zunyi Medical University from February to August 2023. Semi-structured in-depth interviews were conducted, and the Colaizzi 7-step analysis method was applied to inductively extract and refine the themes.Results:A total of six main themes and ten sub-themes were identified through analysis. The main themes were: desires to improve postoperative physical symptoms (gastrointestinal symptoms, hair loss, neurological symptoms, and general symptoms) ; perception of subjective emotions (anxiety, regret, fear, and confidence) ; decreased social adaptability (decline in work ability, impaired social skills) ; general low compliance; desire for professional guidance; and postoperative benefit finding.Conclusions:Six months after LSG, patients primarily experienced physical symptom disturbances, poor psychological states, decreased social adaptability, low compliance, and a desire for professional guidance. However, they also recognized various benefits of the surgery. Healthcare providers should strengthen dynamic symptom assessments and management, guide patients psychologically, enhance social support, and actively improve follow-up and continuous care to help patients improve self-coping abilities and weight loss outcomes.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective:To investigate the correlation between macular cherry red spot (CS) and severity of neurological manifestations in Chinese children with sialidosis (SD) type I.Methods:A evidence-based medical study. "China", "Sialidosis" and "Sialidoses" were used as Chinese and English search terms. The literature was searched in CNKI, Wanfang and PubMed. The cases were all from China and matched the diagnostic criteria. According to the presence or absence of CS in the fundus, the SD children were divided into a group with CS (+) and a group without CS (-), and the correlation between the occurrence of ocular CS and neurological manifestations was compared with meta-analysis by RevMan 5.3 software.Results:Sixty-eight studies were initially retrieved according to the search strategy, and 17 studies were finally included, and 5 studies with CS+ and CS- were meta-analyzed. Among the 43 patients, 28 were male and 15 were female, with a median age of 12 years. Visual impairment was observed in 37 cases (90.2%, 37/41, 2 cases not recorded), and CS was present in 24 cases (55.8%, 24/43). The most common neurological manifestation was myoclonus (97.7%, 42/43), followed by cerebellar ataxia (95.1%, 39/41, 2 cases not recorded) and seizures (91.4%, 32/35, 8 cases not recorded). Pathogenic NEU1 gene mutations were detected in 42 cases and one case was undocumented. The incidence of seizure in group CS+ (100%, 20/20) was higher than that in group CS- (80%, 12/15). Meta-analysis showed that there was no statistically significant difference between the incidence of myoclonus or ataxia [relative risk ( RR)=1.13, 95% confidence interval ( CI) 0.79-1.63, P=0.49] and seizure ( RR=1.13, 95% CI 0.84-2.06, P=0.24) among the children in the CS+ and CS- groups. Conclusions:The incidence of ocular CS in Chinese children with type I SD was 55.8%. There was no correlation with neurological manifestations, however the incidence of seizure was significantly higher in patients with CS than in others without CS.

Objective:To investigate the application of mind map combined with daily mini-clinical evaluation exercise in standardized training of gynecological residents.Methods:A total of 100 trainees who received standardized training in Department of Gynecology, Women and Children's Hospital of Chongqing Medical University, were selected as subjects, and they were divided into control group (traditional teaching) and observation group (mind map combined with daily mini-clinical evaluation exercise) according to the order by which they entered the department for training, with 50 trainees in each group. After teaching, the two groups were compared in terms of assessment results of clinical practice exercise and degree of satisfaction with teaching. SPSS 22.0 statistical software was used for the t-test. Results:After the application of mind map combined with daily mini-clinical evaluation exercise in the standardized training of gynecological residents, compared with the control group, the observation group had significantly higher assessment results of inquiry ability, specialized physical examination, clinical diagnosis, diagnosis and treatment regimen, clinical practice ability, communication ability, clinical thinking ability, decision-making ability for clinical issues, and overall performance ( P<0.05). Compared with the control group, the observation group had significantly higher levels of mastery of clinical inquiry ability, specialized physical examination, development of diagnosis and treatment regimen, doctor-patient communication ability, and clinical practice ability, as well as a significantly higher overall teaching satisfaction score ( P<0.05). Conclusion:Mind map combined with daily mini-clinical evaluation exercise is a simple and feasible teaching method and can help to improve the comprehensive clinical practice ability of trainees receiving standardized residency training, and therefore, it holds promise for application in teaching.

Irritable bowel syndrome (IBS) is characterized by abdominal pain associated with changes in defecation frequency and blood folate level. FODMAP stands for fermentable oligosaccharides, disaccharides, monosaccharides and polyols. High-FODMAP diet could elicit or exacerbate IBS-associated bowel symptoms, which is inadequately recognized among gastroenterologists in China. Here we report an IBS case, focusing on the association between high-FODMAP diet and bowel symptoms and the intervention of low-FODMAP diet.
