AIM: To delineate the specific mutation responsible for retinitis pigmentosa(RP)in a Yi pedigree, and to analyze the correlation of RHO gene mutation with clinical phenotype.METHODS:A comprehensive clinical evaluation was conducted on the proband diagnosed with RP and other familial members, complemented by a thorough ophthalmic examination. Peripheral blood samples were obtained from the proband and familial members, from which genomic DNA was extracte. Subsequent whole exome sequencing(WES)was employed to identify the variant genes in the proband. The identified variant gene was validated through Sanger sequencing, then an in-depth analysis of the mutation genes was carried out using genetic databases to ascertain the pathogenic mutation sites. Furthermore, an exhaustive analysis was performed to delineate the genotype and phenotype characteristics.RESULTS:The RP pedigree encompasses 5 generations with 42 members, including 19 males and 23 females. A total of 13 cases of RP were identified, consisting of 4 males and 9 females, which conforms to the autosomal dominant inheritance pattern. The clinical features of this family include an early onset age, rapid progression, and a more severe condition. The patients were found to have night blindness around 6 years old, representing the earliest reported case of night blindness in RP families. The retina was manifested by progressive osteocytoid pigmentation of the fundus, a reduced visual field, and significantly decreased or even vanished a and b amplitudes of ERG. The combined results of WES and Sanger sequencing indicated that the proband had a heterozygous missense mutation of the RHO gene c.1040C>T:p.P347L, where the 1 040 base C of cDNA was replaced by T, causing codon 347 to encode leucine instead of proline. Interestingly, this mutation has not been reported in the Chinese population.CONCLUSION:This study confirmed that the mutant gene of RP in a Yi nationality pedigree was RHO(c.1040C>T). This variant leads to the change of codon 347 from encoding proline to encoding leucine, resulting in a severe clinical phenotype among family members. This study provides a certain molecular, clinical, and genetic basis for genetic counseling and gene diagnosis of RHO.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Thermal analysis technology has emerged as a pivotal tool for the identification and quality control of traditional Chinese medicine （TCM） owing to its advantages of high sensitivity and capability for simultaneous multi-parameter detection. The application progress on thermogravimetric analysis （TGA）, differential thermal analysis （DTA）, and differential scanning calorimetry （DSC） in four key areas: authenticity identification of herbal medicines, optimization of processing techniques, evaluation of extract thermal stability, and construction of quality evaluation systems were summarized. Thermal analysis technology enables rapid authentication of medicinal materials by establishing a thermal fingerprint. When integrated with hyphenated techniques （e.g., FTIR and GC-MS）, it facilitates in-depth analysis of compositional differences in complex matrices. In Future, the development of thermal analysis databases and multi-technology integration will be expected to further promote the standardization of TCM quality control.

Objective: To investigate the potential efficacy and safety of Lutai Danshen Baishao granules (LDBG) for treating female melasma associated with kidney deficiency and blood stasis patterns. Methods: A randomized, double-blind, placebo-controlled trial was conducted at the Third Central Hospital of Tianjin, China from March to December 2023. A total of 110 female patients with melasma linked to kidney deficiency and blood stasis were enrolled and treated with either LDBG or a placebo twice daily for 60 days. Efficacy was assessed through measures such as the total melasma area, reduced melasma area, reduction rate of melasma area, melasma color score, Melasma Area and Severity Index (MASI) score, and traditional Chinese medicine (TCM) symptom score scale. Safety assessments included routine blood and biochemical tests. Results: Participants in both groups were aged 52–63 years, with no significant differences. After the 2-month intervention, the total melasma area decreased in both groups; however, a greater reduction was observed in the test group [462.50 mm2 (12.81%) vs. 100.00 mm2 (3.11%), P < .001]. Moreover, LDBG treatment significantly reduced the MASI and melasma color scores in the test group (P < .05). The total TCM symptom evaluation score significantly decreased (test group: 6.00 vs. placebo group: 7.00, P = .001), with significant relief in symptoms such as improvement in dark lips, nails, and waist soreness in the test group, compared with that in the placebo group (P < .05). Within-group comparisons revealed that TCM syndrome was significantly alleviated in the test group (P < .05). Conclusion LDBG intervention shows promising effectiveness in reducing female melasma and alleviating TCM syndromes.

Objective:To investigate the endorectal ultrasound findings in rectal neuroendocrine neoplasms (R-NEN) and to compare the diagnostic performance of ERUS and MRI for T staging of R-NENs.Methods:The imaging features of 77 confirmed R-NEN cases with different pathological grades in the Sixth Affiliated Hospital, Sun Yat-sen University from August 2015 to August 2021 were retrospectively analyzed and the abilities of ERUS and MRI for T staging of R-NENs were compared.Results:A total of 77 R-NEN patients underwent preoperative ERUS examinations and detected lesions in 62 patients with a detection rate of 80.52%. Among them, 30 cases underwent simultaneous MRI examinations, and detected lesions in 25 cases with a detection rate of 83.33%, without statistical difference between MRI and ERUS ( P>0.05). R-NEN exhibited hypoechoic nodules with rich blood flow in the submucosa on ERUS. Grade G1 and G2 tumors generally had sizes less than 10 mm, clear boundaries, and regular shapes, while G3 was typically large, irregular, poorly defined, and more likely to invade the musculi propria and serous layer. G3 demonstrated a more profound infiltration level, a less defined border, and a larger diameter than G1 and G2, with statistically significant differences (all P<0.05). For T staging, the accuracy of ERUS was 86.67%, and that of MRI was 94.67%, with no statistical difference ( P>0.05). Conclusions:ERUS is effective for detecting R-NEN lesions and useful for tumor grading with comparable performance to MRI, and should be recommended for preoperative evaluation of neuroendocrine tumors.

With the reform of the national medical and health system entering a new stage of high-quality development of public hospitals,the large-scale implementation of day surgery in hospitals is imminent in the face of increasing patient demand.In this paper,the medical administration management and medical insurance policies related to day surgery in China and their im-pacts were sorted out,and the example of large-scale implementation of day surgery by a specialized ophthalmic medical institu-tion through pre-hospitalization mode was used to illustrate how to use management tools to break through the bottleneck in the promotion process of day surgery,and the positive effect of large-scale development of day surgery on both doctors and patients was expounded.

Objective To discuss the correlation of serum visceraladiposetissue-derived serineproteinase inhibitor(vaspin)and atrial fibrosis biochemical markers in atrial fibrillation(AF)patients.Methods The subjects were selected from inpatients in Shanghai Putuo District People's Hospital during January 2021 to October 2022.Enzyme linked immunosorbent assay(ELISA)was used to determine the levels of serum vaspin,C-terminal propeptide of prollagen type Ⅰ(PⅠCP),matrix metalloproteinase-1(MMP-1),N-terminal type Ⅲ collagen peptide(PⅢNP),tissue matrix metalloproteinase inhibitory factor-1(TIMP-1)of paroxysmal atrial fibrillation(PAF)group,persistent atrial fibrillation(PeAF)group,and control group.The correlation between serum vaspin and the above serum biochemical markers was analyzed.Results ①Levels of serum vaspin(9.51±1.47)ng/ml,PⅠCP(704.83±120.45)ng/ml,MMP-1(5.92±0.73)ng/ml,PⅢNP(63.34±12.24)ng/ml,and TIMP-1(7.56±0.90)ng/ml in PeAF group were significantly higher than those of PAF group and control group(P<0.05);②vaspin was significantly and positively correlated with PⅠCP,MMP-1,PⅢNP,TIMP-1 in PAF group and PeAF group.Conclusion Serum vaspin level of AF patients were significantly high and positively correlated with atrial fibrosis biochemical markers,which indicated that serum vaspin level might be closly related to atrial fibrosis in AF patients.It may be a potential marker to identify the degree of fibrosis in atrial fibrillation.
