To summarize the clinical experience of Professor LIU Shangyi in treating pruritus vulvae. It is believed that women have the physiological characteristics of liver and kidney as the root， and their pubic area is easily attacked by wind-dampness pathogenic qi， so the core mechanism of pruritus vulvae is proposed as wind-dampness accumulation and deficiency of liver and kidney. The core treatment method is to dispel wind-dampness and nourish the liver and kidneys， and modify the Danggui Decoction （当归饮子） to form a self-prescribed Yinyang Formula （阴痒方） as the basic prescription to treat pruritus vulvaen.

Syringa pinnatifolia, belonging to the family Oleaceae, is a species endemic to China. It is predominantly distributed in the Helan Mountains region of Inner Mongolia and Ningxia of China. The peeled roots, stems, and thick branches have been used as a distinctive Mongolian medicinal material known as "Shan-chen-xiang", which has effects such as suppressing "khii", clearing heat, and relieving pain and is employed for the treatment of cardiovascular and pulmonary diseases and joint pain. Over the past five years, significant increase was achieved in research on chemical constituents and pharmacological effects. There were a total of 130 new constituents reported, covering sesquiterpenoids, lignans, and alkaloids. Its effects of anti-myocardial ischemia, anti-cerebral ischemia/reperfusion, sedation, and analgesia were revealed, and the mechanisms of agarwood formation were also investigated. To better understand its medical value and potential of clinical application, this review updates the research progress in recent five years focusing on the chemical constituents and pharmacological effects of S. pinnatifolia, providing reference for subsequent research on active ingredient and support for its innovative application in modern medicine system.

OBJECTIVE: To analyze four patients with a 16q22 fragile site with miscarriage or infertility by using cytogenetic methods. METHODS: Four patients presented at Northwest Women's and Children's Hospital between January 2022 and December 2024 were selected as the study subjects. Peripheral blood samples were collected from the patients and subjected to G-banded chromosomal karyotyping, among whom two were also subjected to copy number variation (CNV) sequencing. This study has been approved by the Ethics Committee of the Hospital (Ethics No. 2020-022). RESULTS: The chromosomal karyotypes of the patients were mos 46,XX,fra(16)(q22)[26]/47,XX,del(16)(q22),+chrb(16)(q22)[4]/46,XX,del(16)(q22)[3]/46,XX[91], mos 46,XY,fra(16)(q22)[21]/46,XY,del(16)(q22)[3]/46,XY[76], mos 46,XX,fra(16)(q22)[21]/ 46,XX,del(16)(q22)[4]/46,XX[75] and mos 46,XX,fra(16)(q22)[16]/46,XX,del(16)(q22)[7]/47,XX,del(16)(q22),+chrb(16)(q22)[6]/47,XX,fra(16)(q22),+chrb(16)(q22)[3]/46,XX[68], respectively. CNV sequencing of patients 2 and 4 revealed no deletion or duplication on chromosome 16. CONCLUSION Identification of the 16q22 fragile site has facilitated genetic counseling for these patients.

Background::An evidence gap still exists regarding the efficacy and safety of tegoprazan in patients with erosive esophagitis (EE) in China. This study aimed to verify the efficacy and safety of tegoprazan vs. esomeprazole in patients with EE in China. Methods::This study was a multicenter, randomized, double-blind, parallel, active-controlled, non-inferiority phase III trial of patients with EE randomized 1:1 to tegoprazan 50 mg/day vs. esomeprazole 40 mg/day. This study was conducted in 32 sites between October 24, 2018 and October 18, 2019. The primary endpoint was the cumulative endoscopic healing rate at week 8. The secondary endpoint included endoscopic healing rate at week 4, changes in the reflux disease questionnaire (RDQ) and gastroesophageal reflux disease health-related quality of life (GERD-HRQL) scores, and symptom improvement. Results::A total of 261 patients were randomized: 132 to the tegoprazan group and 129 to the esomeprazole group. The cumulative endoscopic healing rate at 8 weeks in the tegoprazan group was non-inferior to that of the esomeprazole group (91.1% vs. 92.8%, difference: -1.7%, 95% confidence interval [CI]: -8.5%, 5.0%, P = 0.008). There were no statistically significant differences in the changes in RDQ (total, severity, and frequency) and GERD-HRQL scores between the two groups (all P >0.05). The percentages of days without symptoms, including daytime and nighttime symptoms based on patients' diaries, were similar between the two groups (all P >0.05). In the tegoprazan and esomeprazole groups, 71.5% (93/130) and 61.7% (79/128) of the participants reported adverse events (AEs), 2.3% and 0 experienced serious AEs, while 70.0% and 60.2% had treatment-emergent AEs, respectively. Conclusion::Tegoprazan 50 mg/day demonstrated non-inferior efficacy in healing EE, symptom improvement, and quality of life, and it has similar tolerability compared with esomeprazole 40 mg/day.

Objective:To perform molecular diagnosis and pedigree analysis for one case with α-thalassemia who does not conform to the genetic laws,and explore the effects of a newly discovered rare mutation(HBA2:c.*12G＞A)on clinical phenotypes.Methods:Blood samples of the proband and her family members were collected for blood routine analysis,and the hemoglobin components were analyzed by capillary electrophoresis.The common α-and β-globin gene loci in Chinese population were detected by conventional techniques(Gap-PCR,RDB-PCR).The α-globin gene sequences(HBA1,HBA2)were analyzed by Sanger sequencing.Results:By analyzing the test results of proband and her family members,the genotype of the proband was-α3,7/HBA2:c.*12G＞A,her father was HBA2:c.*12G＞A heterozygous mutation carrier.Conclusion:This study identifies a rare α-globin gene mutation(HBA2:c.*12G＞A)that has not been reported before.It is found that heterozygous mutation carriers present with static α-thalassemia.

Objective To explore the diagnostic value of MRI quantitative enhancement parameters in breast cancer and their rela-tionships with human epidermal growth factor receptor-2(HER-2)and angiopoietin-2(Ang-2).Methods A total of 80 patients with breast cancer were selected as the study objects.The MRI quantitative enhancement parameters[rate constant(Kep),extravascular extracellular space volume fraction(Ve),volume transfer constant(Ktrans)]of all patients with different clinical staging and lymph node metastasis were compared,respectively.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of MRI quantitative enhancement parameters on the expression of HER-2 and Ang-2.Results Kep and Ktrans in stage Ⅱ group were significantly lower than those in stage Ⅲ and Ⅳ groups(F=6.322,F=6.676;P＜0.05).Kep and Ktrans in lymph node metas-tasis group were significantly higher than those in lymph node non-metastasis group(t=4.265,t=4.557;P＜0.05).Kep and Ktrans in HER-2 positive group were significantly higher than those in HER-2 negative group(t=3.988,t=4.616;P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of the combination of Kep and Ktrans for the diagnosis of HER-2 expression in breast cancer patients was 0.887,with specificity of 0.811 and sensitivity of 0.889,respectively.Kep and Ktrans in Ang-2 positive group were signifi-cantly higher than those in Ang-2 negative group(t=2.534,t=3.189;P＜0.05).ROC curve analysis showed that the AUC of the com-bination of Kep and Ktrans for the diagnosis of Ang-2 expression in breast cancer patients was 0.767,with specificity of 0.867 and sensitivity of 0.569,respectively.Conclusion MRI quantitative enhancement parameters can improve the diagnostic value of breast cancer and the expression of HER-2 and Ang-2,which are beneficial to guide the selections of clinical therapeutic regimens.
