ObjectiveTo study the mechanism of compound Xishu granules (CXG) in inhibiting the proliferation of hepatocellular carcinoma cells by regulating ferroptosis. MethodsThe transplanted tumor model of human Huh7 was established with nude mice and the successfully modeled mice were randomized into model, Fufang Banmao (0.21 g·kg-1), low-dose (1.87 g·kg-1) CXG, medium-dose (3.74 g·kg-1) CXG, and high-dose (7.49 g·kg-1) CXG groups. Mice were administrated with drinking water or CXG for 28 days, and the body weight and tumor volume were measured every 4 days. Hematoxylin-eosin staining was employed to observe the histopathological changes of tumors. The cell-counting kit-8 (CCK-8) was used to examine the survival rate of Huh7 cells treated with different concentrations (0, 31.25, 62.5, 125, 250, 500, 1 000 mg·L-1) of CXG for 24 h and 48 h. CA-AM, DCFH-DA, and C11-BODIPY581/591 fluorescent probes were used to determine the intracellular levels of ferrous ion (Fe2+), reactive oxygen species (ROS), and lipid peroxide (LPO), respectively. The colorimetric method was employed to measure the levels of glutathione (GSH) and superoxide dismutase (SOD). Western blot was employed to determine the protein levels of glutathione peroxidase 4 (GPX4), transferrin receptor 1 (TFR1), and ferritin heavy chain 1 (FTH1), respectively. ResultsIn the animal experiment, compared with the model group, the drug treatment groups showed reductions in the tumor volume from day 12 (P<0.01). After treatment, the Fufang Banmao and low-, medium-, and high-dose CXG groups had lower tumor volume, relative tumor volume, and tumor weight than the model group (P<0.05), with tumor inhibition rates of 48.99%, 79.93%, 91.38%, and 97.36%, respectively. Moreover, the CXG groups had lower tumor volume and relative tumor volume (P<0.05 in all the three dose groups) and lower tumor weight (P<0.05 in medium-dose and high-dose groups) than the Fufang Banmao group. Compared with the model group, the drug treatment groups showed reduced number of tumor cells, necrotic foci with karyopyknosis, nuclear fragmentation, and nucleolysis, and the high-dose CXG group showed an increase in the proportion of interstitial fibroblasts. In the cell experiment, compared with the blank group, CXG reduced the survival rate of Huh7 cells in a dose-dependent manner after incubation for 24 h and 48 h (P<0.05). Compared with the blank group, the RSL3 group and the low-, medium-, and high-dose CXG groups showed a decrease in the relative fluorescence intensity of CA-AM and increases in the fluorescence intensity of DCFH-DA and fluorescence ratio of C11-BODIPY581/591, which indicated elevations in the levels of Fe2+ (P<0.01), ROS (P<0.05), and LPO (P<0.01), respectively. Compared with the blank group, the RSL3 and low-, medium-, and high-dose CXG groups showed lowered levels of GSH and SOD (P<0.05). In addition, the RSL3 group and the medium- and high-dose CXG groups showed down-regulated expression of GPX4 and FTH1 (P<0.05), and the low- and high-dose CXG groups presented up-regulated expression of TFR1 (P<0.05). ConclusionCXG suppresses the proliferation of hepatocellular carcinoma cells by inducing ferroptosis via downregulating the GSH-GPX4 signaling axis and increasing intracellular Fe2+and LPO levels.

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of tirzepatide for diabetes mellitus type 2 (T2DM) and long-term weight management, and provide evidence-based basis for clinical drug treatment and health insurance policy formulation. METHODS Computer searches were conducted in Embase, PubMed, the Cochrane Library, CNKI and health technology assessment (HTA) official website from their inception to October 1st 2024 to collect HTA report, systematic review/ meta-analysis and pharmacoeconomic study on tirzepatide for the treatment of T2DM or for weight management. After data extraction and quality evaluation, descriptive analysis was performed on the research results. RESULTS Totally 18 papers were included, including 14 systematic reviews/meta-analyses and 4 pharmacoeconomics studies, and no HTA report was retrieved. In terms of efficacy, most results showed that the tirzepatide 10 mg and 15 mg were significantly better than other glucagon-like peptide-1 (GLP-1) receptor agonists in reducing glycosylated hemoglobin, body weight, and waist circumference (P<0.05). In terms of safety, compared with other GLP-1 receptor agonists, tirzepatide did not increase the incidence of gastrointestinal-related adverse events (AE), the incidence of AE of grade ≥3, or the incidence of severe hypoglycemia (P>0.05). However, tirzepatide 15 mg may significantly increased the incidence of hypoglycemia and the rate of discontinuation due to adverse reactions (P< 0.05). In terms of cost-effectiveness, based on the background of foreign pharmacoeconomic studies, tirzepatide was more cost- effective compared to semaglutide and liraglutide in the treatment of T2DM or for weight management. CONCLUSIONS Tirzepatide at doses of 10 mg and 15 mg has good efficacy and safety for the treatment of T2DM and for long-term weight management. However, when using the 15 mg dose of tirzepatide, close monitoring is required due to the risk of hypoglycemia and discontinuation due to adverse reactions it may pose. Based on pharmacoeconomic studies conducted abroad results, tirzepatide exhibits economic advantages.

ObjectiveTo evaluate the efficacy of Shuanghua drink in treating primary dysmenorrhea in the rat model and explore its mechanism of action. MethodsAn oxytocin-induced writhing mouse model was established to evaluate the analgesic effect of Shuanghua drink. Forty-eight non-pregnant female institute of cancer research (ICR) mice were randomly divided into six groups, including a blank group, a model group, an ibuprofen group (85.00 mg·kg-1), a low-dose group of Shuanghua drink (7.14 mL·kg-1), a medium-dose group of Shuanghua drink (14.28 mL·kg-1), and a high-dose group of Shuanghua drink (28.57 mL·kg-1). Each group consisted of eight mice. All treatment groups received daily intragastric administration at corresponding doses for 10 consecutive days. One hour after the final administration, 2 U of oxytocin was intraperitoneally injected per mouse. The writhing latency and number of writhing within 20 minutes were recorded. A primary dysmenorrhea rat model was established by using estradiol benzoate and oxytocin to evaluate the inhibitory effect of Shuanghua drink on the contraction of uterine smooth muscle. Forty-eight non-pregnant female Sprague-Dawley (SD) rats were divided into six groups, including a blank group, a model group, an ibuprofen group (51.00 mg·kg-1), a low-dose group of Shuanghua drink (4.28 mL·kg-1), a medium-dose group of Shuanghua drink (8.57 mL·kg-1), and a high-dose group of Shuanghua drink (17.10 mL·kg-1). Each group consisted of eight rats. Rats received subcutaneous injections of estradiol benzoate for 10 consecutive days to enhance uterine sensitivity. On the eleventh day, oxytocin (2 U/rat) was intraperitoneally administered to induce abnormal uterine contractions for establishing the primary dysmenorrhea model. All treatment groups received daily intragastric administration from the second day of modeling for 10 days. The effects of Shuanghua drink were evaluated by using parameters including uterine motility and the variation rate of uterine motility. The mechanism of action was investigated in rats with primary dysmenorrhea. The content of prostaglandin F2α (PGF2α), prostaglandin E2 (PGE2), thromboxane B2 (TXB2), prostacyclin metabolite (6-keto-PGF1α), and β-endorphin (β-EP) in uterine tissue of rats was detected by using enzyme-linked immunosorbent assay (ELISA). The changes in the content of nitric oxide (NO) and inducible nitric oxide synthase (iNOS) were analyzed via colorimetric assay. Western blot was performed to determine the content of phosphorylated inhibitor of kappa B kinase beta (p-IKKβ)/IKKβ, phosphorylated inhibitor of kappa B alpha (p-IκBα), IκBα, phosphorylated p65 (p-p65), p65, and cyclooxygenase-2 (COX-2) proteins in uterine tissue of rats. ResultsIn the oxytocin-induced writhing mouse model, the model group exhibited significantly shortened writhing latency and increased writhing frequency compared to the control group (P<0.01). Both the ibuprofen group and the high-dose group of Shuanghua drink displayed prolonged writhing latency (P<0.05), while the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink exhibited reduced writhing frequency (P<0.01). In the primary dysmenorrhea rat model, the uterine motility and its variation rate in the model group were significantly higher than those in the blank group (P<0.01). These parameters were markedly suppressed by ibuprofen and Shuanghua drink at all tested doses (P<0.01). For the mechanism of action, the model group showed significantly increased PGF2α/PGE2, TXB2/6-keto-PGF1α, NO, and iNOS in uterine tissue (P<0.05, P<0.01) and significantly decreased β-EP (P<0.01). These parameters were significantly attenuated in the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink. The PGF2α/PGE2 (P<0.01), TXB2/6-keto-PGF1α (P<0.01), NO (medium-dose group P<0.05), and iNOS (P<0.01) were reduced, and the β-EP (medium-dose group P<0.05) was up-regulated. Compared to the model group, the ibuprofen group and medium-dose group of Shuanghua drink showed significantly increased content of β-EP in the serum of rats (P<0.05). Compared to the blank group, the model group showed significantly elevated expressions of COX-2, p-IKKβ/IKKβ, p-IκBα/IκBα, and p-p65/p65 proteins (P<0.01) and significantly reduced anti-inflammatory protein IκBα (P<0.05). Compared to the model group, the ibuprofen group and the low-dose, medium-dose, and high-dose groups of Shuanghua drink showed significantly reduced expressions of COX-2 (P<0.01), p-IKKβ/IKKβ (P<0.01), p-IκBα/IκBα (P<0.05, P<0.01), and p-p65/p65(P<0.01) and up-regulated expression of IκBα protein (P<0.05, P<0.01). ConclusionShuanghua drink effectively alleviates primary dysmenorrhea through analgesia and suppression of abnormal contractions of uterine smooth muscle. Its mechanism may be mediated by reduced levels of PGF2α/PGE2, TXB2/6-keto-PGF1α, iNOS, and NO, elevated β-EP level, and inhibited COX-2/NF-κB signaling pathway.

The intervention and prevention of perioperative hypothermia is not only reflected in the technical level, but also reveals the important role of humanistic care in the whole intervention work. If perioperative patients have hypothermia, it is likely to cause a series of complications such as postoperative shivering, which seriously threatens the life safety of patients. Prevention and intervention was based on a comprehensive understanding of the causes and hazards of hypothermia, especially the impact on the lives of the elderly. Effective supervision was implemented in the whole process of operation, such as dynamic monitoring of vital signs including body temperature, followed by room temperature regulation, body temperature protection and preoperative and postoperative psychological nursing. At this time, the sense of responsibility, good humanistic care of medical staff are of positive significance to effectively prevent and reduce the probability of perioperative hypothermia and accelerate the postoperative rehabilitation of patients.

OBJECTIVE To provide a reference for the early diagnosis, drug treatment and medication monitoring for patients with Lemierre’s syndrome. METHODS The doctors confirmed the diagnosis of the patient as having Lemierre’s syndrome based on the patient’s condition and the results of metagenomic next-generation sequencing (mNGS), and the clinical pharmacists participated in the treatment process of the patient. During the treatment process, the clinical pharmacists suggested using piperacillin sodium and tazobactam sodium combined with metronidazole for anti-infective treatment against Fusobacterium necrophorum infection; clinical pharmacists recommend anticoagulant treatment with Enoxaparin sodium injection for left internal jugular vein thrombophlebitis. RESULTS The doctors accepted the suggestion of the clinical pharmacists, and the patient’s condition improved after treatment and was allowed to be discharged with medication. CONCLUSIONS By interpreting the results of mNGS, combined with the patient’s condition, the clinical pharmacists assist doctors in formulating individualized anti-infective and anticoagulant plans for the patient and provide medication monitoring, ensuring the safety and effectiveness of the patient’s medication.

Objective:To summarize the clinical features and pregnancy outcomes of fetal micrognathia.Methods:This retrospective study enrolled 52 cases of fetal micrognathia diagnosed at Shandong Provincial Maternal and Child Health Hospital Affiliated to Qingdao University and Affiliated Maternity and Child Health Care Hospital of Nantong University from January 2014 to December 2022. Clinical features, genetic testing results, and pregnancy outcomes of the cases were summarized. These cases were divided into two groups based on whether they were complicated by other system anomalies: non-isolated micrognathia (49 cases) and isolated micrognathia (three cases). The non-isolated micrognathia cases were further divided into two subgroups: cleft palate group (21 cases) and non-cleft palate group (28 cases). Clinical features were compared between different groups. Statistical analysis was performed using two independent samples t-test, Chi-square test, or Fisher's exact test. Results:(1) The non-isolated micrognathia cases were complicated by one to six system anomalies, with the most common being facial anomalies (59.2%, 29/49), followed by circulatory system (51.0%, 25/49), musculoskeletal system (44.9%, 22/49), nervous system (34.7%, 17/49), digestive system (12.2%, 6/49), and urinary system anomalies (8.2%, 4/49). (2) Among 52 cases, nine non-isolated micrognathia cases received genetic testing, and the results indicated six with genetic abnormalities. (3) Forty-seven cases chose to terminate the pregnancies, while the other five cases continued the pregnancies (all fetuses were non-isolated micrognathia) and resulted in live births. Treatment was withdrawn in one live birth due to multiple anomalies, and the other four neonates required mechanical ventilation (two died after withdrawal of treatment; two underwent surgeries after birth and the prognosis of them was good during a one-year outpatient follow-up). (4) The proportion of women with polyhydramnios [28.6% (6/21) vs. 3.6% (1/28), Fisher's exact test, P=0.033] and the proportion of fetuses with confirmed Pierre Robin sequence [85.7% (18/21) vs. 7.1% (2/28), Fisher's exact test, P<0.001] were higher in the cleft palate group than those in the non-cleft palate group. Conclusions:Fetal micrognathia cases revealed by prenatal ultrasound should undergo a comprehensive screening for other system anomalies, especially cleft palate. Fetuses with micrognathia and multiple system anomalies often have a poor prognosis. Besides, it is recommended to take genetic testing. For fetuses with micrognathia, preparations for neonatal resuscitation at birth are essential to avoid adverse outcomes due to breathing difficulties.
