OBJECTIVE To optimize the extraction process of organic acids from Angelica sinensis using deep eutectic solvents （DESs）， and conduct characterization， antioxidant activity evaluation， and extraction mechanism analysis. METHODS The conductor-like screening model for realistic solvation with segment activity coefficients （COSMO-SAC） was employed to screen the types of DESs. With total organic acid content as the response value， single-factor experiments and Box-Behnken response-surface methodology were used to optimize the extraction conditions. Using A. sinensis decoction pieces and/or A. sinensis methanol extract as references， scanning electron microscope and Fourier transform infrared spectrometer （FTIR） were applied to characterize the products. Additionally， the 1，1-diphenyl-2-picrylhydrazyl （DPPH） and 2，2′-azino-bis（3-ethylbenzothiazoline-6- sulfonic acid） （ABTS） free radical scavenging capacities were determined. Density functional theory （DFT） was used to analyze the extraction mechanism of ferulic acid and chlorogenic acid by the DESs. RESULTS & CONCLUSIONS The optimal DESs was choline chloride-propanediol. The optimal extraction conditions for organic acids from A. sinensis were as follows： choline chloride- propanediol molar ratio of 1∶1， DESs water content of 70%， solid-liquid ratio of 1∶10， heating temperature of 57 ℃， and heating and stirring time of 8 min. In three validation experiments， the total organic acid content was 2.92 mg/g， yielding a relative error of 0.34% compared to the predicted value （2.91 mg/g）. Compared with A. sinensis decoction pieces and methanol extracts， the agglomerated structure of the DESs extract powder almost disappeared， showing the presence of lamellar structures similar to those of the intestinal wall. Compared with the methanol extract， the DES extract exhibited higher FTIR characteristic peak intensity and peak area integration， as well as stronger scavenging capacities against DPPH and ABTS free radicals. The extraction of organic acids from A. sinensis by DESs is the result of the combined effects of polarity matching， hydrogen bonding， and structural adaptation.

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. CONCLUSION Tiaowei Jiannao acupuncture improves the insomnia symptoms in patients with ischemic stroke, improves the quality of sleep, increases the deep sleep, promotes the recovery of neurological function, and relieves the depression. It is effective and safe for the treatment of PISI.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test（DVAT） in vestibular migraine（VM）. Methods:A total of 50 VM patients（case group） and 50 healthy subjects（control group） diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test（vHIT）, caloric test, and Dizziness Handicap Inventory（DHI） assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss（DVALoss）, as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group（P<0.001）. In both groups, age was significantly and positively correlated with DVALoss（P<0.001）. Within the case group, DVALoss was strongly and positively correlated with DHI scores（r=0.807, P<0.001）; it was negatively correlated with the vestibulo-ocular reflex（VOR） gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores（R²=0.713）, with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.

Objective To explore the efficacy and safety of pegylated doxorubicin liposome(PLD)in neoadjuvant chemotherapy(NAC)for breast cancer.Methods A total of 126 breast cancer patients treated with the NAC regimen containing PLD in the Third Xiangya Hospital of Central South University from Janu-ary 2018 to December 2022 were selected as the research subjects.The clinical efficacy,pathological efficacy and occurrence of adverse reactions of the patients were observed,and total pathological complete response(tpCR)rates of different molecular subtypes were analyzed.The changes in left ventricular ejection fraction(LVEF)were compared between before and after treatment.Results Among 126 patients,the clinical efficacy of NAC in 119 cases was evaluated,and the objective response rate(ORR)was 67.2％(80/119).A total of 123 patients were evaluated for the pathological efficacy,breast cancer pathological complete response(bpCR)rate was 13.8％(17/123);tpCR rate was 12.2％(15/123),in which the the human epidermal growth factor receptor 2(HER2)positive[hormone receptor(HR)negative]type had the highest rate(33.3％),followed by triple-negative(21.7％).There was no hand-foot syndrome occurred,and only one case developed the grade 2 oral mucositis.LVEF showed no statistically significant difference between before and after treatment[69.9％(51.0％,87.0％)vs.69.0％(57.0％,85.0％)](P＞0.05).Conclusion The NAC regimen containing PLD has a better effect on HER2—positive and triple-negative breast cancer.

Objective To explore the clinical effect of active risk prevention nursing on the prevention of skin injury in patients with esophageal cancer during radiotherapy.Methods A total of 102 patients who underwent radiotherapy for esophageal cancer in Jiangsu Cancer Hospital from December 2022 to November 2023 were enrolled.They were assigned to control group(n=51,routine nursing)and study group(n=51,routine nursing+active risk prevention)according to the random number table.The skin injury,quality of life,and nursing satisfaction were compared between the two groups.Results The skin injury in the study group at 20 Gy,40 Gy and at the end of radiotherapy was significantly slighter than that in the control group(P<0.05).After 4 weeks of intervention,the total score of SF-36 and scores in all dimensions in the study group were higher than those in the control group,and the degree of nursing satisfaction in the study group was significantly higher than that in the control group(72.55%vs 94.12%,χ2=8.541,P<0.05).Conclusion Active risk prevention can reduce skin injury,improve quality of life,and help to improve nursing satisfaction in patients with esophageal cancer during radiotherapy.

Primary hyperparathyroidism is a disease with a large potential population. Some cases of primary hyperparathyroidism are non-primary, preventable and curable at early stage, requiring long-term follow-up after surgery. Therefore, all-round and full-cycle management are necessary for primary hyperparathyroidism, which involves an enhancing focus on etiological prevention, early detection, prompt diagnosis, timely intervention, multi-disciplinary standardized diagnosis and treatment, and postoperative scientific management. Meanwhile, implementing a "12+5+1" multidisciplinary joint diagnosis and treatment model, along with a two-way referral model, to achieve the transition from a disease-oriented diagnostic and treatment model to a patient-oriented, all-round and full-cycle interdisciplinary management model. This management can reduce the incidence and recurrence rate of primary hyperparathyroidism, and related osteoporosis or osteopenia, fractures, nephrolithiasis, metastatic vascular calcification, and systemic abnormal migratory calcium deposits, improve the overall quality of life and prognosis of patients.

The incidence of parathyroid hyperfunction is high and its clinical manifestations are diverse. Some patients develop chest tightness and palpitations as the main discomfort, which may be caused by the hypocalcemia and hypercalcemia related to negative calcium balance and parathyroid hyperfunction. We report a case of 53 years old male with parathyroid hyperfunction who was diagnosed with osteoporosis before and received conventional regular supplementation of vitamin D and calcium supplements. However, his condition worsened and he developed chest tightness and palpitation. After 1 month of sufficient supplementation of calcium, the symptoms of chest tightness and palpitation disappeared completely. Then we continued to provide the patients enough vitamin D and calcium supplementation actively. After 1 year of follow-up, the patient's condition was stable. His discomfort of chest tightness and palpitation never recurred, and all the bone metabolism indicators returned to normal.

Surgery is the important treatment for each type of thyroid cancer. Single or multiple parathyroid injuries or blood supply disorders may occur during the operation, resulting in dramatic decline of parathyroid hormone and hypocalcemia after operation, which is common in clinical practice. After discharge, chronic hypocalcemia can cause great physical and psychological pain to patients. Although the residual parathyroid glands can compensate after surgery in some cases, long-term negative calcium balance and postoperative hypocalcemia may cause excessive hyperplasia of the residual parathyroid glands, resulting in parathyroid hyperfunction or even hyperparathyroidism, which can lead to osteoporosis, urinary calculi, metastatic vascular calcification, and systemic abnormal migratory calcium deposits. It’s advisable to enhance the awareness of the cause and harm of the postoperative hypocalcemia, evaluate and diagnose it early, and actively intervene in every stage of before, during and after the operation and long-term follow-up, which can effectively reduce the occurrence and severity of hypocalcemia and improve the postoperative life quality and the prognosis.

Thyroid cancer is the common malignant tumor in the neck, and surgery is the important treatment measure for it. Some patients suffer from hypoparathyroidism and hypocalcemia after thyroidectomy, which will seriously affect the patient’s life quality and prognosis. This article reported a case of 42 years old female patient with hypocalcemia for 6 years after total thyroidectomy due to thyroid cancer, who still had frequent hypocalcemia with high dose of oral calcium and active vitamin D supplementation. Long-term and frequent facial and limb numbness, convulsions, epileptic-like seizures and sudden unconsciousness afflicted her due to hypocalcemia. After admission, her symptoms were obviously relieved after one week of adequate calcium supplementation through oral administration or intravenous infusion under close monitoring. Upon discharge she was able to maintain the normal level of blood calcium by decreased dose of oral calcium supplementation alone. Long-term limb numbness, convulsions, low back pain, shoulder pain, walking instability and other symptoms disappeared basically. The epileptic-like seizures did not recur. During six months of follow-up, her blood calcium was still well controlled in normal level.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.
