Objective To evaluate the clinical efficacy of a novel sleep-aid decoction in treating elderly insomnia patients with different traditional Chinese medicine (TCM) constitutional types, and its effects on neurotransmitter and inflammatory factor levels. Methods A total of 200 patients with four different TCM constitutions-peaceful, Qi-deficient, Yin-deficient, and Yang-deficient-were recruited. Peripheral blood neurotransmitter and inflammatory factor levels were measured for variations among insomnia patients across different constitutions. These patients were treated using the novel sleep-aid decoction, the effects of which were evaluated based on changes in neurotransmitters and inflammatory factors. Results Compared to the peaceful constitution group, insomnia patients with Qi-deficient, Yin-deficient, and Yang-deficient constitutions exhibited significantly elevated baseline levels of neurotransmitters (5-HT, GABA) and inflammatory factors (IL-6, TNF-α, IL-1β, CRP). Following the treatment, the Qi-deficient and Yin-deficient groups showed a marked increase in 5-HT levels, restored balance of Glu, GABA, and melatonin, and significant reductions in IL-6 and TNF-α levels. The overall effective rate was 83.5%, with optimal efficacy observed in the Qi-deficient (97.72%) and Yin-deficient (95.34%) groups. Conclusion The novel sleep-aid decoction is effective in treating insomnia in elderly patients, with the best results observed in the Qi-deficient and Yin-deficient constitution groups.

OBJECTIVE: Hepatocellular carcinoma (HCC) is a leading cause of mortality worldwide. Huachansu (Cinobufacini) is active extract isolated from the dry skin of Bufo Bufo gargarizans. It has now been widely used in clinical treatment of cancer, this study is to clarify the material basis of down-regulation of thymidylate synthase (TYMS) induced by Huachansu. METHODS: Our study utilized UPLC-MS/MS to identify major bioactive components from Huachansu. Cell Counting Kit 8 (CCK-8) assay and clone formation assay were used to examine the cell viability of tumor cells. TYMS and γ-H2AX level were detected by using quantitative real-time RT-PCR and/or western blotting. Small interfering RNA (siRNA) transfection was used to explore whether inhibition of TYMS could enhance the suppressive effect of Huachansu on cell growth of HCC cells. RESULTS: In our study, firstly, we identify 21 major bioactive components from Huachansu. CCK-8 assay results showed that Huachansu and its bioactive bufadienolides (Bufalin, Bufotalin, Cinobufotalin, Desacetylcinobufagin, Arenobufagin, Telocinobufagin, and Resibufogenin) significantly inhibited the proliferation of HepG2 and SK-HEP-1 cells in a dose- and time-dependent manner. Further molecular mechanistic investigation demonstrates that Huachansu significantly suppresses thymidylate synthase (TYMS), the enzyme which provides the sole de novo source of thymidylate for DNA synthesis. The inhibition of TYMS could lead to cell-cycle block and DNA damage of HCC cells. Furthermore, we identified that Huachansu markedly increased γ-H2AX expression, which indicated the presence of DNA damage. Moreover, we confirmed that transfection of cells with small interfering RNA specific to TYMS could increase the suppressive effects of Huachansu on the HCC cells proliferation. Quantitative RT-PCR analysis showed that Huachansu treatment had no effect on the transcription level of TYMS. Furthermore, proteasomal inhibitor MG132 could block TYMS inhibition induced by Huachansu, and concomitant administration of protein synthesis inhibitor cycloheximide (CHX) with Huachansu could further suppress the protein level of TYMS, indicating that Huachansu promotes proteasome-dependent degradation of TYMS in liver cancer cells. More importantly, the bioactive bufadienolides of Huachansu such as Bufalin, Bufotalin, Cinobufotalin, Desacetylcinobufagin, Arenobufagin, Telocinobufagin, and Resibufogenin could also significantly restrain the protein level of TYMS, revealing the material basis of inhibition of TYMS exposed to Huachansu. 5-Fluorouracil (5-FU) is a TYMS inhibitor, we also evaluate the effects of the combined treatment of Huachansu with 5-FU, the results show that interactions between Huachansu and 5-FU are synergistic or antagonistic. Thus, in clinical, attention should be paid to the dosage of Huachansu in combination with 5-FU. CONCLUSION Huachansu inhibits the growth and induces DNA damage of human HCC cells through proteasome-dependent degradation of TYMS, bioactive bufadienolides are the material basis of down-regulation of TYMS induced by Huachansu.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.

Objective:To establish an irritant contact dermatitis(ICD)model induced by sodium dodecyl sulfate(SDS)in mice,and explore its endotype to provide an experimental and theoretical basis for subsequent precise treatment.Methods:Mice were randomly divided into two groups(model group and control group),4%SDS was topically applied to induce ICD in mice,saline was used on control group,the dose and frequency were consistent with model group,and the skin lesions of mice were observed.Epidermal thickness and inflammatory cell infiltration were analyzed by HE staining,toluidine blue staining and immunofluorescence staining.Real-time quantitative PCR was performed to investigate mRNA expression levels of cytokines.Results:Compared with control group,mice in ICD model group showed epidermal thickness on the back of neck,and the numbers of inflammatory cells were increased in dermis.The number of neutrophils,macrophages and T cells were increased.Expressions of Il17a and Il17f mRNA levels were increased.Conclusion:SDS-induced ICD model is successfully established,with the elevated infiltration of neutrophils,macrophages and T cells,and secretion of type 17 cytokines.

Hypertensive intracerebral hemorrhage (ICH) is mostly single in basal ganglia, thalamus and pons. Simultaneous hemorrhage in other brain regions is relatively rare, accounting for only 5.6% of all hemorrhagic strokes, while bilateral symmetrical hemorrhage is extremely rare. A case of bilateral basal ganglia symmetrical hemorrhage is reported for clinical reference.

To explore the relationship between progesterone receptor (PGR) gene G1978T polymorphism and endometrial carcinoma. METHODS: After searching PubMed, EMBASE, Wan-fang and CNKI databases for literatures on PGR G1978T genotyping of endometrial cancer patients, the data were extracted and odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using STATA15. The whole blood samples of endometrial carcinoma cases (EC group) and normal women (control group) were collected. Allelic-specific primers matching G1978T wild type G allele and mutant type T allele were designed with 3' terminal phosphorothioate modification, and the two-directional primer extension was performed using Exo + polymerase to genotype PGR gene G1978T polymorphism and Sanger sequencing was used to verify the genotype. RESULTS: PGR gene G1978T mutation was marginally associated with endometrial carcinoma risk (ORper allele =1.10, 95%CI=0.98-1.24, P= 0.072). At the same time, only 1 normal blood samples were found with PGR gene G1978T mutation, and the differences in genotypes and allele frequency between the case group and the control group were not statistically significantP>0.05. CONCLUSION: The G1978T polymorphism of the PGR gene maybe not be associated with the risk of endometrial carcinoma.

Objective:To summarize the evidence of cold therapy for patients after knee joint replacement, so as to provide theoretical support for the practical implementation of cold therapy in patients after knee joint replacement in clinical practice.Methods:The literature on cold therapy for patients after knee joint replacement was systematically searched in relevant databases and websites at home and abroad. The search period was from database establishment to September 2022. The evaluation of literature quality and evidence extraction were independently completed by two researchers.Results:A total of 17 articles were included, including two clinical practice guidelines, five systematic reviews, six randomized controlled trials, and four expert consensuses. After independent evaluation and evidence extraction by two researchers, a total of 19 pieces of evidence were collected from 5 aspects: evaluation and education, observation of cold therapy, cold therapy tools, cold therapy parameters, and cold therapy effects. Among them, 8 pieces of A-level recommended evidence and 11 pieces of B-level recommended evidence.Conclusions:Cold therapy for patients after knee joint replacement is widely accepted and applied. Medical and nursing personnel should prioritize patient safety and formulate scientific cold therapy plans based on various factors such as individual differences, patient preferences, actual clinical scenarios, differences in medical equipment, medical and nursing personnel technical level, and cost-effectiveness, in order to maximize patient benefits.

Objective:To compare the dosimetric difference between intensity-modulated photon radiaotherapy (IMRT) planning and intensity-modulated proton radiotherapy (IMPT) planning for glioma.Methods:The clinical data of 15 glioma patients who underwent IMRT in ion medical center of the First Affiliated Hospital of USTC from November 2020 to April 2022 were retrospectively analyzed. IMRT planning and IMPT planning were designed for the image of each patient in the therapy planning system. Main dosimetric parameters were compared including plan target volume (PTV), coverage index (CI), dose homogeneity index (HI), and maximal dose (D max) and mean dose (D mean) of organs at risk between both plans. Results:There were no significant differences between IMRT planning and IMPT planning in terms of D max and D mean of PTV1 and PTV2, CI and HI (all P > 0.05). Compared with IMRT planning, brainstem D mean [6.92 GyE (0.09 GyE, 12.58 GyE) vs. 24.41 GyE (2.59 GyE, 34.18 GyE)], left optic nerve D max [0.78 GyE (0.04 GyE, 25.18 GyE) vs. 20.42 GyE (6.38 GyE, 37.17 GyE)], left optic nerve D mean [0.10 GyE (0.01 GyE, 11.63 GyE) vs. 9.74 GyE (2.99 GyE, 20.87 GyE)], right optic nerve D mean [1.57 GyE (0.13 GyE, 14.90 GyE) vs. 14.08 GyE (2.66 GyE, 23.67 GyE)], left len D max [0 GyE (0 GyE, 2.91 GyE) vs. 4.84 GyE (1.42 GyE, 5.48 GyE)], left len D mean [0 GyE (0 GyE, 1.73 GyE) vs. 3.84 GyE (1.25 GyE, 4.30 GyE)], right len D max [0.25 GyE (0.04 GyE, 4.55 GyE) vs. 4.28 GyE (1.58 GyE, 5.84 GyE)], right len D mean [0.16 GyE (0.01 GyE, 1.95 GyE) vs. 3.73 GyE (1.04 GyE, 4.86 GyE)], pituitary D max [6.97 GyE (0.18 GyE, 39.70 GyE) vs. 36.60 GyE (2.74 GyE, 45.19 GyE)], pituitary D mean [1.36 GyE (0.06 GyE, 13.85 GyE) vs. 24.74 GyE (2.42 GyE, 32.80 GyE)], hippocampus D max [5.10 GyE (0.24 GyE, 26.52 GyE) vs. 35.83 GyE (5.03 GyE, 46.11 GyE)], hippocampus D mean [0.36 GyE (0.04 GyE, 25.65 GyE) vs. 18.79 GyE (2.37 GyE, 28.10 GyE)] in IMPT planning were lower, and the differences were statistically significant (all P < 0.05). There were no statistical differences in brainstem D max [51.98 GyE (0.66 GyE, 53.43 GyE) vs. 53.29 GyE (3.87 GyE, 53.48 GyE)], right optic nerve D max [9.60 GyE (0.01 GyE, 43.32 GyE) vs. 25.37 GyE (3.45 GyE, 41.25 GyE)] of both plans (all P > 0.05). Conclusion:In the radiotherapy for glioma, IMRT and IMPT can meet the dose demand in clinic. Furthermore, IMPT planning can protect organs at risk and reduce radiation dose in hippocampus, brainstem, optic nerve, lens and pituitary.

Objective:To investigate the effects of ginsenoside Rg1 (GS-Rg1) on the secretion of exosomes (MSC-Exo) and expression of angiogenesis related microRNAs (miRNAs) in mesenchymal stem cells.Methods:Human umbilical cord blood mesenchymal stem cells (hUCBMSCs) were divided into experimental group and control group. The experimental group was treated with GS-RG1 at a final concentration of 40 mg/L, while the control group was treated with phosphate buffered saline (PBS) at the same volume. Both groups were cultured for 24 h. The morphology of MSC-Exo was observed by transmission electron microscopy; the characteristic surface markers were identified by Western blot; the concentration of MSC-Exo was detected by dicootanobutyric acid protein quantification method, and the expression of 8 miRNAs related to angiogenesis in MSC-Exo was detected by reverse transcription polymerase chain reaction (RT-PCR).Results:After 24 h of incubation, MSC-Exo with a circular membrane vesicle structure was visible. MSC-Exo was positive for the expression of the characteristic surface markers CD9, CD63 and TSG101. After 24 h of intervention, the concentration of MSC-Exo protein were (1.080±0.019)μg/μl and (0.881±0.032)μg/μl in the experimental group and control group, respectively, with statistically significant difference ( P<0.01). The expression of miR-126-3p, miR-21, miR-146a-5p and miR-125b-5p in the GS-Rg1 group were significantly higher than that in the control group, while the expression of miR-16-5p was significantly lower than that in the control group (all P<0.05). Conclusions:GS-Rg1 promotes the secretion of MSC-Exo and enhances the expression of angiogenesis-related miRNAs within Exo to promote angiogenesis.

Objective:To explore the value of application and manipulation technique of neuroendoscope in microsurgical clipping of ruptured posterior communicating artery(PCoA)aneurysms via keyhole approaches.Methods:From January 2018 to December 2020, the clinical data of 52 patients who received microsurgical clipping for ruptured via keyhole approach were retrospectively analysed. Forty-one patients had the intraoperative endoscopic monitoring. The supraorbital keyhole approach or pterional keyhole approach was applied based on the characteristics of the aneurysms. According to the in-surgery requirement, a 30° rigid neuroendoscope was used before and/or after clipping. All patients entered postoperative follow-up in outpatient clinic and were evaluated with the modified Rankin Scale(mRS).Results:All 52 patients had 52 ruptured PCoA aneurysms. Eighteen of the patients were treated via supraorbital keyhole approach and 34 via pterion keyhole approach. Pre-and post-clipping endoscopic observation were carried out in 12 cases and 29 only with post-clipping endoscopic observation. Residual aneurysmal neck was detected in 3 patients. Missed clipping of perforators was found in 2 patients and followed by proper adjustment of clips. All patients received follow-up angiographic examinations. Total obliteration of the aneurysm and an intact of internal carotid artery and PCoA were found in 41 patients by the intraoperative endoscopic observation. Two residual aneurysmal neck were detected in 11 patients without intraoperative endoscopic observation. After 11 to 45 months of follow-up, all patients had good recovery(mRS 0-1).Conclusion:It is a safe and effective method with endoscopic observation during microsurgical clipping procedure for ruptured PCoA aneurysms via keyhole approaches. It can effectively make up for the insufficient visual angle of microscope, realise the anatomical relationship between the aneurysm and adjacent structures, and avoid residual aneurysmal neck and an iatrogenic injury to the parent artery and perforators.
