OBJECTIVE:
To observe the efficacy and safety of Tiaowei Jiannao acupuncture (acupuncture for regulating defensive qi and nourishing brain) for post-ischemic stroke insomnia (PISI).
METHODS:
A total of 96 patients with PISI were randomized into an acupuncture group (32 cases, 1 case was excluded), a medication group (32 cases, 1 case dropped out, 1 case was excluded) and a sham-acupuncture group (32 cases, 1 case dropped out, 1 case was excluded). In the acupuncture group, Tiaowei Jiannao acupuncture was applied at bilateral Shenmai (BL62), Zhaohai (KI6), Hegu (LI4), Taichong (LR3), and Baihui (GV20), Sishencong (EX-HN1), Yintang (GV24+), Shenting (GV24), once a day, 1-day interval was taken after 6-day treatment, for 3 weeks totally. In the medication group, eszopiclone tablet was given orally, 1-3 mg a time, once a day for 3 weeks. In the sham-acupuncture group, non-invasive sham acupuncture was applied, the acupoint selection, frequency and course of treatment were the same as the acupuncture group. Before treatment, after 2,3 weeks of treatment, the scores of Pittsburgh sleep quality index (PSQI), self-rating sleep scale (SRSS), National Institutes of Health Stroke scale (NIHSS), Hamilton depression scale-17 (HAMD-17) were observed; before and after treatment, the sleep parameters were recorded using polysomnography (PSG); and the efficacy and safety were evaluated after treatment in the 3 groups.
RESULTS:
After 2,3 weeks of treatment, the scores of PSQI, HAMD-17 and SRSS in the acupuncture group and the medication group, as well as the SRSS scores in the sham-acupuncture group were decreased compared with those before treatment (P<0.05); after 2 weeks of treatment, the NIHSS score in the acupuncture group was decreased compared with that before treatment (P<0.05); after 3 weeks of treatment, the NIHSS scores in the acupuncture group, the medication group and the sham-acupuncture group were decreased compared with those before treatment (P<0.05). After 3 weeks of treatment, the scores of PSQI, SRSS, HAMD-17 and NIHSS in the acupuncture group and the medication group, as well as the NIHSS score in the sham-acupuncture group were decreased compared with those after 2 weeks of treatment (P<0.05). After 2,3 weeks of treatment, the scores of PSQI, SRSS and HAMD-17 in the acupuncture group and the medication group were lower than those in the sham-acupuncture group (P<0.05), the NIHSS scores in the acupuncture group were lower than those in the medication group and the sham-acupuncture group (P<0.05); after 3 weeks of treatment, HAMD-17 score in the acupuncture group was lower than that in the medication group (P<0.05), the NIHSS score in the medication group was lower than that in the sham-acupuncture group (P<0.05). Compared before treatment, after treatment, the total sleep time was prolonged (P<0.05), the wake after sleep onset, sleep latency, and non-rapid eye movement (NREM) sleep latency were shortened (P<0.05), the sleep efficiency was improved (P<0.05), the number of awakenings was reduced (P<0.05), the percentage of rapid eye movement (REM%) and the percentage of NREM stage 1 (N1%) were decreased (P<0.05), the percentage of NREM stage 2 (N2%) and the percentage of NREM stage 3 (N3%) were increased (P<0.05) in the acupuncture group and the medication group; the sleep latency was shortened in the sham-acupuncture group (P<0.05). After treatment, the PSG indexes in the acupuncture group and the medication group were superior to those in the sham-acupuncture group (P<0.05); in the acupuncture group, the number of awakenings was less than that in the medication group (P<0.05), the REM% and N1% were lower than those in the medication group (P<0.05), the N2% and N3% were higher than those in the medication group (P<0.05). The total effective rate were 93.5% (29/31) and 90.0% (27/30) in the acupuncture group and the medication group respectively, which were higher than 10.0% (3/30) in the sham-acupuncture group (P<0.05). There was no serious adverse events in any of the 3 groups.

OBJECTIVES:
The purinergic receptor P2X2 (P2RX2) encodes an ATP-gated ion channel permeable to Na+, K+, and especially Ca²⁺. Loss-of-function mutations in P2RX2 are known to cause autosomal dominant nonsyndromic deafness 41 (DFNA41), which manifests as high-frequency hearing loss, accelerated presbycusis, and increased susceptibility to noise-induced damage. Zebrafish, owing to their small size, rapid development, high fecundity, transparent embryos, and high gene conservation with humans, provide an ideal model for studying human diseases and developmental mechanisms. This study aims to generate a p2rx2 knockout zebrafish model using CRISPR/Cas9 gene editing system to investigate the effect of p2rx2 deficiency on the auditory system, providing a basis for understanding P2RX2-related hearing loss and developing gene therapy strategies.
METHODS:
Two CRISPR targets (sgRNA1 and sgRNA2) spaced 47 bp apart were designed within the zebrafish p2rx2 gene. Synthesized sgRNAs and Cas9 protein were microinjected into single-cell stage Tübingen (TU)-strain zebrafish embryos. PCR and gel electrophoresis verified editing efficiency at 36 hours post-fertilization (hpf). Surviving embryos were raised to adulthood (F0), tail-clipped, genotyped, and screened for positive mosaics. F1 heterozygotes were generated by outcrossing, and F2 homozygous mutants were obtained by intercrossing. Polymerase chain reaction (PCR) combined with sequencing verified mutation type and heritability. At 5 days post-fertilization (dpf), YO-PRO-1 staining was used to examine hair cell morphology and count in lateral line neuromasts and the otolith region. Auditory evoked potential (AEP) thresholds at 600, 800, 1 000, and 2 000 Hz were measured in nine 4-month-old wild type and mutant zebrafish per group.
RESULTS:
A stable p2rx2 knockout zebrafish line was successfully established. Sequencing revealed a 66 bp insertion at the first target site introducing a premature stop codon (TAA), leading to early termination of protein translation and loss of function. Embryos developed normally with no gross malformations. At 5 dpf, mutants exhibited significantly reduced hair cell density in the otolith region compared with wild type, although lateral line neuromasts were unaffected. AEP testing showed significantly elevated auditory thresholds at all 4 frequencies in homozygous mutants compared with wild type (all P<0.001), indicating reduced hearing sensitivity.
CONCLUSIONS
We successfully generated a p2rx2 loss-of-function zebrafish model using CRISPR/Cas9 technology. p2rx2 deficiency caused hair cell defects in the otolith region and increased auditory thresholds across frequencies, indicating its key role in maintaining zebrafish auditory hair cell function and hearing perception. The phenotype's restriction to the otolith region suggests tissue-specific roles of p2rx2 in sensory organs. This model provides a valuable tool for elucidating the molecular mechanisms of P2RX2-related hearing loss and for screening otoprotective drugs and developing gene therapies.

OBJECTIVE To explore the effect of volatile oil of Ligusticum chuanxiong on the transdermal properties and cytotoxicity of triptolide in vitro. METHODS The chemical constituents of the volatile oil of L. chuanxiong were analyzed by gas chromatography-mass spectrometry. The lower abdominal skin of KM mice was separated and divided into triptolide group, triptolide in compatibility with volatile oil of L. chuanxiong groups at 1∶10, 1∶50, 1∶100 (hereinafter referred to as “compatibility 1∶10”“compatibility 1∶50”“compatibility 1∶100” groups). After the skin of mice in each group was fully exposed to 0.2 g of the corresponding cream for 24 h, the cumulative transdermal dose (Qn) of triptolide in the receiving solution of each group was determined by high-performance liquid chromatography, and the transdermal absorption rate (Jss) was calculated. Human immortalized keratinocytes (HaCat) were used as a model, the CCK-8 method was used to detect the cell survival rate of different concentrations of the volatile oil of L. chuanxiong and triptolide before and after compatibility. RESULTS A total of 62 chemical constituents of the volatile oil of L. chuanxiong were identified, including Z-ligustilide, senkyunolide, and β-selinene. The Qn (P< 0.01) and Jss of triptolide increased within 24 h in the compatibility 1∶10 and 1∶50 groups, while the Qn (P<0.05) and Jss decreased in the compatibility 1∶100 group as compared with the triptolide group. Compared with the triptolide group, the cell survival rate of HaCat was significantly increased in the compatibility 1∶10 and 1∶50 groups when the triptolide concentrations were 36, 72 and 144 ng/mL (P<0.05 or P<0.01); while the cell survival rate of HaCat was decreased in the compatibility 1∶100 group, but the difference was not statistically significant (P>0.05). CONCLUSIONS When the compatibility ratio of triptolide and volatile oil of L. chuanxiong was 1∶10 or 1∶50, it can promote the transdermal absorption of triptolide and reduce the cytotoxicity of triptolide to HaCat.

ObjectiveTo investigate the value of serum Fetuin-A and Fetuin-B combined with Homeostasis Model Assessment of Insulin Resistance (HOMA-IR) in predicting nonalcoholic fatty liver disease (NAFLD). MethodsA total of 120 patients with NAFLD who attended Department of Gastroenterology, The First Affiliated Hospital of Dali University, from June 2020 to June 2021, and 120 healthy individuals who underwent physical examination at Physical Examination Center during the same period of time were enrolled as subjects, and clinical data were collected from all subjects. The serum levels of Fetuin-A and Fetuin-B were measured. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups; the multivariate Logistic regression analysis was used to assess the risk factors for NAFLD. The receiver operating characteristic (ROC) curve was plotted to evaluate the predictive efficacy of Fetuin-A and Fetuin-B combined with HOMA-IR in NAFLD patients. ResultsCompared with the healthy control group, the NAFLD group had significantly higher levels of body mass index, systolic blood pressure, diastolic blood pressure, alanine aminotransferase, aspartate aminotransferase, fasting blood glucose, fasting insulin, triglycerides, HOMA-IR, Fetuin-A, and Fetuin-B (all P<0.05). The multivariate Logistic regression analysis showed that Fetuin-A (odds ratio [OR]=1.010, 95% confidence interval [CI]: 1.001 — 1.020, P<0.05), Fetuin-B (OR=1.113, 95%CI: 1.021 — 1.214, P<0.05), and HOMA-IR (OR=24.053, 95%CI: 2.624 — 220.470, P<0.05) were independent risk factors for NAFLD. The ROC curve analysis showed that Fetuin-A, Fetuin-B or HOMA-IR alone had an area under the ROC curve (AUC) of 0.637 (95%CI: 0.551 — 0.722), 0.853 (95%CI: 0.796 — 0.912), and 0.837 (95%CI: 0.763 — 0.912), respectively, and Fetuin-A combined with Fetuin-B, Fetuin-A combined with HOMA-IR, and Fetuin-B combined with HOMA-IR had an AUC of 0.853 (95%CI: 0.795 — 0.911), 0.843 (95%CI: 0.770 — 0.916), 0.922 (95%CI: 0.877 — 0.967), respectively, while the combination of these three indicators had an AUC of 0.922 (95%CI: 0.877 — 0.966). ConclusionFetuin-A and Fetuin-B have a certain value in predicting NAFLD, and Fetuin-B combined with HOMA-IR tends to have a higher predictive value.
