Objective The Nuangong Waifu formula （NGWFF） is a traditional Chinese medicine prescription that has been used in gynecology of traditional Chinese medicine in our hospital for many years. It has a certain effect on preventing postoperative intrauterine re-adhesion. To further retrospectively analyze the clinical efficacy of NGWFF. Methods A total of 200 patients who were diagnosed with intrauterine adhesions and underwent intrauterine adhesion separation from January 2018 to December 2020 were retrospectively included. They were divided into control group and observation group according to different drug use for postoperative prevention of re-adhesion, with 100 cases in each group. All patients were given oral estrogen and progesterone （ethinyl estradiol tablets 0.037 5 mg, q12 h, or estradiol valerate tablets 3 mg, q12 h, a total of 21 days, 7 days after estrogen therapy plus dydrogesterone 20 mg, qd or progesterone capsules 200 mg, qd） to promote endometrial growth. In the control group, 100 patients only used estrogen and progesterone after operation. In the observation group, 100 patients were treated with NGWFF at Guanyuan acupoint （four fingers under the navel）, once a day. Both groups were evaluated for the degree of intrauterine adhesions under hysteroscopy and the effective rate after 3-5 menstrual cycles of drug treatment. Results Compared with using estrogen and progesterone alone, combination use of NGWFF significantly decreased in the scores of intrauterine adhesions under hysteroscopy （2.41±1.19 vs 3.31±1.18, P=0.00）, and the effective rate was also significantly higher than that in the control group （ 86 % vs 47 %, P<0.000）. Conclusion The combination use of NGWFF was more effective than using estrogen and progesterone alone in preventing re-adhesion after intrauterine adhesions， which provided a scientific basis for the clinical application of NGWFF.

OBJECTIVE: To explore the relationship between the geriatric nutritional risk index (GNRI) and cognitive function. METHODS: A cross-sectional study method was conducted. People aged ≥ 60 years from the National Health and Nutrition Examination Survey (NHANES) databases from 1999 to 2002 and 2011 to 2014 were included as study subjects. The participants were divided into three groups based on their GNRI scores: a medium-high risk group (82 ≤ GNRI < 92), a low risk group (92 ≤ GNRI < 98), and a no-risk group (GNRI ≥ 98). Demographic characteristics (gender, age, race, education), chronic diseases [chronic bronchitis, emphysema, thyroid problems, coronary heart disease, angina pectoris, stroke, hypertension, diabetes mellitus, and depression score on the patient health questionnaire (PHQ-9)], lifestyle habits (history of smoking, hours of sleep), etc., were collected. Cognitive function was assessed using the consortium to establish a registry for Alzheimer's disease word learning subtest (CERAD-WL), animal fluency test (AFT), and digit symbol substitution test (DSST) for the 2011-2014 data, while only the DSST was used for the 1999-2002 data. Differences in the above information among the GNRI cohorts were compared. Factors affecting cognitive function in the population were analyzed using multifactorial Logistic regression. RESULTS: 2 653 participants from 2011 to 2014 and 2 380 participants from 1999 to 2002 were enrolled, with a total of 5 033 participants in the study. There were statistically significant differences in age, stroke, diabetes mellitus, DSST score, AFT score, CERAD score test 1 recall (Cst1), and CERAD score test 2 recall (Cst2) among the GNRI groups. Multifactorial Logistic regression analysis of data from 2011 to 2014 showed that in model 3 (DSST score, age, gender, race, marriage, education, hours of sleep, history of smoking, emphysema, thyroid problems, chronic bronchitis, coronary heart disease, angina pectoris, hypertension, diabetes mellitus, depression score on the PHQ-9, and stroke) adjusted for all covariates, GNRI was a protective factor for DSST [odds ratio (OR) = 1.03, 95% confidence interval (95%CI) was 1.00 to 1.05, P = 0.03]; Logistic regression analyse for 1999 to 2002 and 2011 to 2014 showed a significant association even after adjustment for covariates (OR = 1.02, 95%CI was 1.00 to 1.03, P = 0.02). Subgroup Logistic regression analyses of the total population from 2011 to 2014 showed a significant association between GNRI and DSST scores (OR = 1.02, 95%CI was 1.01 to 1.03, P < 0.001), with significant associations in the age subgroups of 60 to 64 years old, across gender, non-Hispanic Whites and Blacks, by education, and by marital status associations were significant (all P < 0.05). Subgroup Logistic regression analyse of the total populations from 1999 to 2002 and 2011 to 2014 showed a significant association between the GNRI and DSST score (OR = 1.01, 95%CI was 1.01 to 1.02, P < 0.001), but did not show a significant year difference (interaction P = 0.503), and the newly found in the smoking population the association was also more significant (P < 0.01). CONCLUSION The GNRI correlates with the presence of cognitive functions related to processing speed, sustained attention, and executive function, and may be able to serve as an indicator for the assessment or prediction of related cognitive functions.

Objective:This study evaluates the horizontal sound localization ability of young and middle-aged individuals with symmetric sensorineural hearing loss (SNHL) in noisy environments. It also examines the impact of hearing loss severity and signal-to-noise ratio (SNR) on localization accuracy.Methods:In this cross-sectional study, conducted from April 2023 to April 2024, 135 young and middle-aged patients (73 males and 62 females, aged 18-60 years) with SNHL who sought care at Beijing Chaoyang Hospital, were categorized into mild, moderate, and moderate-to-severe hearing loss groups (45 per group), with 45 normal-hearing controls (23 males and 22 females, aged 20-60 years). Participants completed localization tasks in quiet and noisy environments with SNR levels of 5 dB, 0 dB, -5 dB, and-10 dB. Root mean square error (RMSE) was used to measure localization accuracy. Repeated measures ANOVA assessed the effects of hearing loss and SNR on RMSE, while, Pearson correlation evaluated the relationship between binaural 4-frequency pure-tone average (4fPTA) and RMSE. Multiple linear regression analyzed the predictive role of 4fPTA and age.Results:(1) Two-way repeated measures ANOVA showed that both hearing loss severity and SNR significantly affected RMSE ( F=92.67, P<0.01; F=430.29, P<0.01), with a significant interaction between the two factors( F=92.67, P<0.01). (2) RMSE increased with hearing loss severity. At SNRs of 5 dB, 0 dB, and-5 dB, the moderate-to-severe group had significantly higher RMSE than the mild and moderate groups ( P<0.01). No significant differences were found between mild and moderate groups ( P=0.53, 0.57, 0.22). At-10 dB SNR, significant differences were observed across all groups ( P<0.01). (3) RMSE increased non-linearly as SNR decreased. Mean RMSE values under quiet conditions and at SNRs of 5 dB, 0 dB, -5 dB, and-10 dB were (7.43±5.01)°, (9.80±5.74)°, (11.60±6.22)°, (14.56±7.07)°, and (18.74±8.02)°, respectively. (4) RMSE was significantly positively correlated with binaural 4fPTA ( r=0.54-0.58, P<0.01). Multiple linear regression analysis indicated that the binaural average 4fPTA significantly predicted RMSE ( P<0.01), explaining 30.5%-34.1% of RMSE variance. Age did not significantly contribute to RMSE variation. Conclusions:The degree of hearing loss and background noise SNR significantly affect horizontal sound localization in young and middle-aged SNHL patients. RMSE increases with hearing loss severity and decreases with higher SNR. The interaction between hearing loss and SNR is significant, and RMSE correlates with binaural 4fPTA. However, the regression model based on 4fPTA and age explains only part of the RMSE variance, suggesting other contributing factors.

Objective:To investigate the factors influencing horizontal sound localization ability in patients with unilateral sensorineural hearing loss (USHL), with the aim of providing evidence-based guidance for clinical rehabilitation.Methods:This cross-sectional study included 43 patients diagnosed with USHL (22 males, 21 females; age range: 30-60 years, mean age: 46.5 years), recruited from Beijing Chaoyang Hospital, Capital Medical University, between October 2023 and April 2024. A control group of 20 age-matched normal-hearing participants (8 males, 12 females; mean age: 45.5 years) was also enrolled. Data collected included demographic variables, four-frequency pure-tone averages (4fPTA at 500, 1 000, 2 000, and 4 000 Hz) for both ears, and duration of hearing loss. Based on the residual hearing in the affected ear, USHL patients were divided into a group with residual hearing (defined as having at least one frequency threshold ≤65 dBHL) and a group with no detectable hearing (all frequencies >65 dBHL). Furthermore, patients in the residual hearing group were categorized by hearing loss severity into those with moderate hearing loss (35 dBHL ≤4fPTA <50 dBHL) and those with moderate-to-severe hearing loss (4fPTA≥50 dBHL). All participants underwent horizontal sound localization testing using speech stimuli under four listening conditions: quiet, and noise at signal-to-noise ratios (SNRs) of +5 dB, 0 dB, and -5 dB. Localization performance was quantified using root-mean-square error (RMSE), and data were analyzed using two-way ANOVA and Pearson correlation in SPSS 26.0.Results:Both the degree of hearing loss and background SNR significantly influenced localization accuracy (hearing level: F=47.59, P<0.01; SNR: F=69.79, P<0.01), with a significant interaction between the two factors ( F=2.81, P<0.01). In quiet environments, even patients with moderate hearing loss demonstrated significantly poorer localization performance compared to normal-hearing controls ( P<0.01). Among those with residual hearing, localization ability at SNR=+5 dB was not significantly different from that in quiet ( P>0.05), but performance deteriorated significantly at SNR=0 dB ( P<0.001). In contrast, patients without residual hearing exhibited significant deficits even at SNR=+5 dB ( P<0.001). Pearson correlation analysis revealed no significant association between RMSE and sex, age, or duration of hearing loss (all P>0.05). However, a strong positive correlation was observed between hearing loss severity and RMSE across all noise conditions ( r=0.760-0.800, all P<0.001), indicating that worse hearing thresholds were associated with poorer localization performance. Conclusions:Even moderate unilateral sensorineural hearing loss can impair horizontal sound localization, and this deficit is exacerbated by increasing hearing loss severity and background noise. Both hearing threshold and SNR are key determinants of localization ability and should be prioritized when designing individualized rehabilitation and intervention strategies for USHL patients.

Objective:This article introduces a novel technique for totally laparoscopic, right thoracic approach, esophagojejunostomy for digestive tract reconstruction.Methods:A retrospective analysis was conducted on the clinical data of patients with adenocarcinoma of the esophagogastric junction who successfully underwent totally laparoscopic esophagojejunostomy via the right thoracic approach at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, between February 2022 and March 2022.The surgical procedure was performed as follows:(1)Following total laparoscopic resection of the gastric tumor and lymph node dissection, the specimen was transected distal to the tumor margin. The specimen was then placed into a retrieval bag and extracted through the umbilical observation port.(2)Dissection was continued through the esophageal hiatus to mobilize the esophagus. The tumor-bearing tissue, along with the esophagus, was delivered into the thoracic cavity via the esophageal hiatus.(3)The jejunum was transected 20 cm distal to the ligament of Treitz. The distal Jejunum was mobilized for 15-20 cm and subsequently delivered into the thoracic cavity through the esophageal hiatus.(4)A Roux-en-Y jejunojejunostomy was constructed 45-50 cm distal to the cut end of the distal jejunal limb; the mesenteric defect was closed, and the duodenal stump was reinforced.(5)The patient was repositioned into the left lateral decubitus position. Port placement was established as follows: the observation port at the 7th intercostal space (ICS) in the right midaxillary line, the main operating port at the 4th ICS in the anterior axillary line, and the assistant operating port at the 9th ICS in the scapular line.(6)The main operating port incision was enlarged. Using a purse-string instrument, the esophagus was clamped and transected at least 5 cm proximal to the upper tumor margin, and the specimen was removed. (7)The distal jejunum was delivered into the thoracic cavity via the esophageal hiatus. Under total laparoscopic visualization, esophagojejunostomy was completed.Results:Both patients who underwent totally laparoscopic esophagojejunostomy via the right thoracic cavity successfully completed the procedure without conversion to laparotomy, unplanned reoperation, or any intraoperative/postoperative complications. The patients recovered well postoperatively, with no evidence of abdominal or thoracic hemorrhage. Postoperative computed tomography (CT) scans of the chest and abdomen confirmed the absence of anastomotic leakage or other related complications.Conclusions:The esophagojejunostomy was performed totally laparoscopically via the right thoracic cavity. This approach overcomes the drawback of significant trauma associated with open surgery while ensuring safe esophageal resection margins and thorough lymph node dissection. This technique offers advantages including minimal invasiveness, accelerated postoperative recovery, and a reduced incidence of reflux esophagitis. To our knowledge, no similar method of digestive tract reconstruction has been reported in the literature. Its novelty and clinical potential may offer new therapeutic options for patients with Siewert type II adenocarcinoma of the esophagogastric junction (AEG).
