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.

[Objective] To analyse and predict the tendencies of using erythrocyte blood in Changsha based on the autoregressive integrated moving average (ARIMA) model, long short-term memory (LSTM) and ARIMA-LSTM combination model, so as to provide reliable basis for designing a feasible and effective blood inventory management strategy. [Methods] The data of erythrocyte usage from hospitals in Changsha between January 2012 and December 2023 were collected, and ARIMA model, LSTM model and ARIMA-LSTM combination model were established. The actual erythrocyte consumption from January to May 2024 were used to assess and verify the prediction effect of the models. The extrapolation prediction accuracy of the models were tested using two evaluation indicators: mean absolute percentage error (MAPE) and root mean square error (RMSE), and then the prediction performance of the model was compared. [Results] The RMSE of LSTM model, optimal model ARIMA(1,1,1)(1,1,1)12 and ARIMA-LSTM combination model were respectively 5 206.66, 3 096.43 and 2 745.75, and the MAPE were 18.78%,11.54% and 9.76% respectively, which indicated that the ARIMA-LSTM combination model was more accurate than the ARIMA model and LSTM model, and the prediction results was basically consistent with the actual situation. [Conclusion] The ARIMA-LSTM model can better predict the clinical erythrocyte consumption in Changsha in the short term.

[Objective] To evaluate the efficacy and safety of sacral neuromodulation (SNM) in the treatment of patients with benign prostatic hyperplasia (BPH) complicated with underactive bladder (UAB) who respond poorly to transurethral resection of the prostate (TURP). [Methods] A retrospective analysis was performed on 10 patients with BPH and UAB treated with TURP by the same surgeon in Zhongda Hospital Southeast University during Jan.2018 and Jan.2023.The residual urine volume was not significantly relieved after operation, and the maximum urine flow rate and urine volume per discharge were not significantly improved.All patients underwent phase I SNM, and urinary diaries were recorded before and after surgery to observe the average daily frequency of urination, volume per urination, maximum urine flow rate, and residual urine volume. [Results] The operation time was (97.6±11.2) min.During the postoperative test of 2-4 weeks, if the residual urine volume reduction by more than 50% was deemed as effective, SNM was effective in 6 patients (60.0%). Compared with preoperative results, the daily frequency of urination [(20.2±3.8) times vs. (13.2±3.2) times], volume per urination [(119.2±56.7) mL vs. (246.5±59.2) mL], maximum urine flow rate [(8.7±1.5) mL/s vs. (16.5±2.6) mL/s], and residual urine volume [(222.5±55.0) mL vs. (80.8±16.0) mL] were significantly improved, with statistical significance (P<0.05). There were no complications such as bleeding, infection, fever or pain.The 6 patients who had effective outcomes successfully completed phase II surgery, and the fistula was removed.During the follow-up of 1 year, the curative effect was stable, and there were no complications such as electrode displacement, incision infection, or pain in the irritation sites.The residual urine volume of the other 4 unsuccessful patients did not improve significantly, and the electrodes were removed and the vesicostomy tube was retained. [Conclusion] SNM is safe and effective in the treatment of BPH with UAB patients with poor curative effects after TURP.

ObjectiveTo investigate the anti-Alzheimer's disease (AD) effect of Dipsacus asper(DA) in the Caenorhabditis elegans model, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α (PPARα)/transcription factor EB (TFEB) pathway. MethodsFirst, transgenic AD C. elegans individuals were assigned into the blank control, model, positive control (WY14643, 20 µmol·L-1), and low-, medium-, and high-dose (100, 200, and 400 mg·L-1, respectively) DA groups. The amyloid β-42 (Aβ42) formation in the muscle cells, the paralysis time, and the deposition of amyloid β-protein (Aβ) in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ, LC3I, LAMP2, and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα, and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain (LBD). ResultsCompared with the model group, the positive control group and 200 and 400 mg·L-1 DA groups showed prolonged paralysis time (P<0.05), and all the treatment groups showed decreased Aβ deposition in the head (P<0.01). DA within the concentration range of 50-500 mg·L-1 did not affect the viability of BV2 cells. In addition, DA enhanced the autophagy flux (P<0.05), up-regulated the mRNA levels of beclin1, Atg5, LAMP2, and CLN2 (P<0.05, P<0.01), promoted the nuclear translocation of TFEB (P<0.05), increased LAMP2 expression and autophagy flux (P<0.05, P<0.01), and enhanced the transcriptional activities of PPARα and TFEB (P<0.01). The positive control group and 200 and 400 mg·L-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus (P<0.01). UPLC-MS detected nine known compounds of DA, from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

ObjectiveTo observe the antidepressant effect of Chaihu Shugansan combined with ferulic acid on the rat model of chronic unpredictable mild stress (CUMS) and explore the mechanism from the histomorphology of frontal cortex, expression of key molecules in the brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB) signaling pathway, and changes in monoamine neurotransmitter levels. MethodsSixty adult male SD rats were randomized into six groups (n=10): blank control, depression model, Chaihu Shugansan (3.3 g·kg-1·d-1), ferulic acid (50 mg·kg-1·d-1), Chaihu Shugansan (3.3 g·kg-1·d-1) + ferulic acid (50 mg·kg-1·d-1), and fluoxetine (2.1 mg·kg-1·d-1). Rats in other groups except the blank control group were subjected to a mild chronic unpredictable stress stimulus every day. Seven stimuli were used, including fasting with free access to water for 24 h, water deprivation with free access to food for 24 h, wetting the bedding with water in the cage, restraint for 3 h, tail clamping for 1 min, swimming in ice water at 4 ℃, and day and night reversal. Each stimulus was used 1 to 3 times, and the modeling lasted for a total of 21 days. At the same time of stimulation, rats in each medication group were treated with corresponding agents by gavage, while those in the blank control group and the depression model group received equal volumes of normal saline by gavage. The open field test, sucrose preference test, and forced swimming test were conducted before and after modeling. The rats were anesthetized by intraperitoneal injection of 3% pentobarbital sodium, and the frontal cortex was isolated on ice. The mRNA and protein levels of BDNF, TrkB, and cyclic adenosine monophosphate-responsive element-binding protein (CREB) in the frontal cortex were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The levels of monoamine neurotransmitters 5-hydroxytryptamine (5-HT), dopamine (DA), and norepinephrine (NE) in the frontal cortex were determined by enzyme-linked immunosorbent assay. Light microscopy was employed to observe the histopathological changes in the frontal cortex. ResultsCompared with the blank control group, the depression model group showed reduced body mass (P<0.05, P<0.01), decreased number of crossings and rearings in the open field test and sucrose preference (P<0.01), prolonged time of immobility in the forced swimming test (P<0.01), reduced neuronal cells, increased necrotic cells, and darkening cell staining in the frontal cortex, down-regulated mRNA and protein levels of BDNF, TrkB, CREB, and lowered levels of 5-HT, NE, and DA in the frontal cortex (P<0.01). Compared with the depression model group, each intervention group showed improved general state, increased body mass (P<0.05), increased number of crossings (P<0.05), shortened immobility time in the forced swimming test (P<0.01), increased neuronal cells, reduced necrotic cells, and lightened cellular staining in the frontal cortex, up-regulated mRNA and protein levels of BDNF, TrkB and CREB, and elevated levels of 5-HT, NE, and DA in the frontal cortex (P<0.01). Moreover, the Chaihu Shugansan + ferulic acid group outperformed the Chaihu Shugansan group and the ferulic acid group in increasing the body mass and the 5-HT content in the frontal cortex (P<0.05). The combination group outperformed the Chaihu Shugansan group regarding the number of rearings and up-regulation in the mRNA level of BDNF in the frontal cortex (P<0.05), and it was superior to the ferulic acid group in terms of shortening the immobility time in the forced swimming test, up-regulating the mRNA levels of BDNF, TrkB, and CREB and the protein levels of BDNF and CREB in the frontal cortex, and increasing the DA content in the frontal cortex (P<0.05). ConclusionChaihu Shugansan combined with ferulic acid can exert antidepressant effect on the rat model of CUMS by regulating the BDNF/TrkB signaling pathway and monoamine neurotransmitter content in the frontal cortex. Moreover, the antidepressant effect of Chaihu Shugansan combined with ferulic acid was more significant than that of Chaihu Shugansan and ferulic acid used alone.

Based on the trinity life view of ''physique, Qi, and spirit'', Chaihu Jia Longgu Mulitang treats the patient's physical symptoms, disorders of Qi movement, and disorders of consciousness, covering the overall treatment and comprehensive nursing of physique, Qi, and spirit. It is widely applied and recognized for its efficacy in modern clinical practice. This paper explored the treatment effect of Chaihu Jia Longgu Mulitang from the trinity life view of ''physique, Qi, and spirit''. This formula mainly targeted patients with Qi deficiency caused by cold, leading to a syndrome of Qi stagnation and water retention in the Triple Energizer Meridian of Hand Lesser Yang (TE), as well as fire-heat syndrome in the Large Intestine Meridian of Hand Yang Brightness (LI) and Stomach Meridian of Foot Yang Brightness (ST), accompanied by disorder of nutrient-blood and subsequent spirit and soul unrest. Accurately judging the imbalance of the patient's physique, Qi, and spirit and using an appropriate combination of medicinals can achieve balance among the three to achieve the best effect. The treatment strategy of Chaihu Jia Longgu Mulitang is as follows: For disorders of Qi movement, such as Qi deficiency, Qi stagnation, and gastrointestinal fire-heat, Ginseng Radix et Rhizoma and Bupleuri Radix-Scutellariae Radix, and Rhei Radix et Rhizoma are used in combination. For physical symptoms such as water retention and disorder of nutrient-blood, Poria-Pinelliae Rhizoma-Zingiberis Rhizoma Recens, as well as Cinnamomi Ramulus-Jujubae Fructus are used in combination. Finally, Os Draconis-Ostreae Concha-Plumbum Rubrum is used to calm the spirit and soothe the soul. According to existing research, Chaihu Jia Longgu Mulitang has shown good efficacy in treating a variety of complex clinical diseases. This article provides a comprehensive interpretation of Chaihu Jia Longgu Mulitang from the perspective of the trinity life view of ''physique, Qi, and spirit'', offering new insights for clinical syndrome differentiation, treatment, and prescription.

The Solomon four-group design, a critical method for improving internal validity in clinical research, can reduce bias and control the interference of Hawthorne effects and pretest sensitization on research results, which offers unique advantages in evaluating complex intervention outcomes. This paper systematically outlined the core framework and key points of statistical analysis of the Solomon four-group design, summarized its applications in clinical research at home and abroad, explored its advantages and limitations, and discussed the potential value in traditional Chinese medicine (TCM) clinical trials. It is believed that the Solomon four-group design can help distinguish between testing effects and intervention effects in TCM clinical studies, and reduce the bias in the evaluation of subjective indicators. Meanwhile, given the complexity of the Solomon four-group design and the particularity of TCM clinical research, it is proposed that future TCM clinical studies should focus on using psychological scales, know-ledge, attitude, and behavior measurements, and other similat evaluations as endpoints. It also advocates strengthening interdisciplinary collaboration to provide new methodological paths for TCM clinical research.

Objective: To investigate the precise detection methods for weak partial D type 15 and evaluate their implications for blood transfusion safety, along with the development of corresponding strategies. Methods: A combination of serological methods, including the microplate method, indirect antiglobulin tube method, and microcolumn gel card method, was employed to identify RhD-negative and RhD variant samples. RhD-negative samples were screened for the presence of RHD genes using whole-blood direct PCR amplification. Subsequently, RhD variant samples and RhD-negative samples containing RHD genes underwent full-coding-region sequencing of the RHD gene to confirm their genotypes. The genotyping results were further correlated with the serological test findings for comprehensive analysis. Results: Among 615 549 first-time healthy blood donors, 3 401 samples with an RhD-negative phenotype and 156 samples with RhD variant were identified. Of the 3 401 RhD-negative samples, 1 054 were found to harbor RHD genes. Gene sequencing analysis of the 156 RhD variants and the 1 054 serological negative samples revealed that 89 samples contained the RHD
15 (c. 845G>A) allele. Conclusion: The integration of serological testing methods and genotyping technologies for the precise determination of RhD blood type plays a critical role in ensuring the safety and compatibility of blood transfusions.
