ObjectiveTo provide a reference for the rational clinical use of cold Chinese medicines by sorting and analyzing their properties， flavors， meridian tropism， primary therapeutic indications， methods of administration， dosages， and precautions as recorded in the 2020 edition of Pharmacopoeia of the People's Republic of China （Chinese Pharmacopoeia）. MethodsCold Chinese medicines for internal and external use included in the 2020 edition of Chinese Pharmacopoeia were entered one by one， and their efficacy， properties， flavors， meridian tropism， methods of administration， dosages， and usage precautions were statistically classified and summarized to guide clinical medication use. ResultsA total of 259 cold Chinese medicines for internal use were included and categorized into 18 efficacy groups， mainly comprising heat-clearing drugs， water-excreting and dampness-draining drugs， and phlegm-resolving， cough- and asthma-relieving drugs. Their predominant flavors were bitter， sweet， and pungent， and they primarily entered the liver， lung， and stomach meridians. The main methods of administration included decocting first， grinding into powder for oral use， or preparing into pills or powders， with most dosages ranging from 9 to 15 g. A total of 83 cold Chinese medicines for external use were included， involving 16 efficacy categories. Their main flavors were bitter， sweet， and pungent， primarily entering the liver， lung， and large intestine meridians. The main external application methods were grinding into powder for topical use or preparing decoctions for fumigation and washing， with most dosages ranging from 9 to 15 g. Whether for internal or external use， cold Chinese medicines should be used with caution or contraindicated in pregnant women. ConclusionThe cold Chinese medicines included in the 2020 edition of the Chinese Pharmacopoeia are mainly suitable for patients with carbuncles， swellings， and coughs. However， in clinical practice， it is necessary to strictly follow the principles of syndrome differentiation and treatment， pay attention to administration methods and dosages， and use cold medicines rationally and effectively to improve clinical efficacy.

[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.

OBJECTIVE To investigate the effects of clopidogrel on the pharmacokinetics and pharmacodynamics of ciprofol in rats. METHODS Eighteen male SD rats were randomly divided into control group， clopidogrel normal-dose group and clopidogrel high-dose group， with 6 rats in each group. Among them， rats in the normal-dose group and high-dose group were given 7.5 mg/kg and 15 mg/kg clopidogrel by gavage， respectively， and rats in the control group were given the same volume of 0.5% sodium carboxymethyl cellulose solution， once a day， for 14 consecutive days. Afterward， 2.4 mg/kg ciprofol was injected by tailvein and blood samples were collected from the inner canthus of the eye at 2， 4， 8， 12， 16， 20， 30， 45 and 60 min after the end of the administration. During this period， the duration of the loss of righting reflex （LORR） in rats was counted. After the proteins were precipitated by acetonitrile， the rat plasma sample was analyzed by LC-MS/MS using deuterated ciprofol as the internal standard， Symmetry C18 as the chromatographic column， and acetonitrile-0.01% ammonia solution containing 5 mmol/L ammonium acetate （gradient elution） as the mobile phase to detect the concentration of ciprofol in the plasma. The pharmacokinetic parameters in rats were calculated by using DAS 2.0 software. RESULTS Compared with control group， area under the drug concentration-time curve and mean residence time of ciprofol increased or prolonged significantly， while plasma clearance decreased significantly in clopidogrel normal-dose and high-dose groups； the duration of LORR in rats was prolonged by 19.5% and 23.9%， with statistical difference （P＜0.05）. However， there was no statistically significant difference in the pharmacokinetic parameters or LORR duration of ciprofol between the different dose groups of clopidogrel （P＞0.05）. CONCLUSIONS Clopidogrel could inhibit the metabolism of ciprofol in rats and prolong the duration of LORR.

With the widespread use of antibiotics, drug-resistant bacterial infections have become a significant threat to human health. Finding new antibacterial strategies that can effectively control drug-resistant bacterial infections has become an urgent task. Unlike small molecule drugs that target bacterial proteins, antisense oligonucleotide (ASO) can target genes related to bacterial resistance, pathogenesis, growth, reproduction and biofilm formation. By regulating the expression of these genes, ASO can inhibit or kill bacteria, providing a novel approach for the development of antibacterial drugs. To overcome the challenge of delivering antisense oligonucleotide into bacterial cells, various drug delivery systems have been applied in this field, including cell-penetrating peptides, lipid nanoparticles and inorganic nanoparticles, which have injected new momentum into the development of antisense oligonucleotide in the antibacterial realm. This review summarizes the current development of small nucleic acid drugs, the antibacterial mechanisms, targets, sequences and delivery vectors of antisense oligonucleotide, providing a reference for the research and development of antisense oligonucleotide in the treatment of bacterial infections.

OBJECTIVE To provide medication reference for duloxetine use in clinical settings， particularly for patients with depression in primary medical institutions in Xinjiang that lack therapeutic drug monitoring conditions. METHODS The medical records of 281 depression inpatients taking duloxetine in the First Affiliated Hospital of Xinjiang Medical University from January 2022 to December 2023 were retrospectively collected. They were divided into training set （196 cases） and test set （85 cases） in the ratio of 7∶3. Feature selection was performed by encapsulating random forests （RF） with recursive feature elimination. Four machine learning algorithms， namely support vector machine， RF， extreme gradient boosting （XGBoost） and artificial neural network， were used to construct duloxetine blood concentration prediction model. The prediction performance of the models was evaluated and compared by coefficient of determination （R2）， mean absolute error （MAE） and root mean squared error （RMSE）. The feature of the selected optimal model was explained by Shapley additive explanation method， and the importance ranking of the features and the influence on the prediction results of duloxetine blood concentration were determined. RESULTS A total of 29 characteristic variables were selected， including age， ethnicity， body mass index（BMI）， etc. XGBoost showed the highest R2 （0.808）， and the lowest MAE （7.644） and RMSE （10.808）. The ranking of feature importance for predicting the blood concentration of duloxetine was as follows： BMI＞age＞other 20 feature sets （including liver and kidney function and biochemical indicators）＞daily dosage＞comorbidities＞combination therapy＞ethnicity＞white blood cell count＞hemoglobin＞height. CONCLUSIONS XGBoost model possesses the best prediction performance of duloxetine blood concentration； BMI and age have a greater impact on the prediction of duloxetine blood concentration.

OBJECTIVE To provide a reference for individualized treatment and pharmaceutical care for patients with breast cancer complicated with chronic kidney disease （CKD）. METHODS Clinical pharmacists participated in the anti-tumor treatment and pharmaceutical care for a breast cancer patient with CKD. Clinical pharmacists reviewed guidelines and literature to assist the clinical physician in formulating the initial neoadjuvant treatment plan （docetaxel+trastuzumab+paltuzumab） and provided monitoring recommendations for potential adverse drug reactions， such as vomiting， myelosuppression， renal impairment， cardiotoxicity. In response to the patient’s acute kidney injury after treatment， clinical pharmacists assisted the physician in analyzing the cause of the adverse reaction through causality assessment. Taking into account the patient’s preferences， docetaxel was substituted with paclitaxel （which did not require dose adjustment based on renal function）. The clinical pharmacists collaborated with the physician to establish a postoperative targeted therapy regimen （trastuzumab+pertuzumab）. Taking into account the patient’s positive estrogen receptor status， the clinical pharmacists recommended to initiate regular anastrozole administration after the completion of radiotherapy and undergo periodic bone density assessments. RESULTS The clinical physician accepted the suggestions from the clinical pharmacists. The patient successfully completed preoperative neoadjuvant chemotherapy and postoperative targeted therapy， and was discharged with medication （anastrozole）. During the treatment process， the patient did not experience adverse reactions such as myelosuppression， cardiotoxicity， or the occurrence of osteoporosis. CONCLUSIONS Clinical pharmacists analyzed and adjusted the preoperative and postoperative antitumor treatment plans based on the patient’s renal function. They promptly assessed the correlation between antitumor drugs and acute kidney injury， and actively implemented comprehensive pharmaceutical care to ensure medication safety for breast cancer patients with CKD.

Background: and Purpose Symptomatic intracranial hemorrhage (sICH) following endovascular thrombectomy (EVT) is a severe complication associated with adverse functional outcomes and increased mortality rates. Currently, a reliable predictive model for sICH risk after EVT is lacking. Methods: This study used data from patients aged ≥20 years who underwent EVT for anterior circulation stroke from the nationwide Taiwan Registry of Endovascular Thrombectomy for Acute Ischemic Stroke (TREAT-AIS). A predictive model including factors associated with an increased risk of sICH after EVT was developed to differentiate between patients with and without sICH. This model was compared existing predictive models using nationwide registry data to evaluate its relative performance. Results: Of the 2,507 identified patients, 158 developed sICH after EVT. Factors such as diastolic blood pressure, Alberta Stroke Program Early CT Score, platelet count, glucose level, collateral score, and successful reperfusion were associated with the risk of sICH after EVT. The TREAT-AIS score demonstrated acceptable predictive accuracy (area under the curve [AUC]=0.694), with higher scores being associated with an increased risk of sICH (odds ratio=2.01 per score increase, 95% confidence interval=1.64–2.45, P<0.001). The discriminatory capacity of the score was similar in patients with symptom onset beyond 6 hours (AUC=0.705). Compared to existing models, the TREAT-AIS score consistently exhibited superior predictive accuracy, although this difference was marginal. Conclusions The TREAT-AIS score outperformed existing models, and demonstrated an acceptable discriminatory capacity for distinguishing patients according to sICH risk levels. However, the differences between models were only marginal. Further research incorporating periprocedural and postprocedural factors is required to improve the predictive accuracy.

Background: En bloc resection is recommended for the treatment of malignant and aggressive benign spinal tumors; however, it often requires a combined anterior-posterior approach, which is usually accompanied by longer surgical duration, increased blood loss, larger trauma, and surgical complexity. The present study describes a novel rotation-reversion technique for en bloc resection of the thoracic and upper lumbar spinal tumors using a posterior-only approach and evaluate its safety and efficacy. Methods: Thirteen patients with thoracic and upper lumbar (L1-L3) spinal tumors were treated with en bloc resection using the rotation-reversion technique through a posterior-only approach at our institution between 2015 and 2023. The clinical characteristics and surgical results of the patients were reviewed and analyzed. Results: Posterior-only en bloc resection was performed successfully in all 13 patients using the rotation-reversion technique, with a median follow-up of 30.4 months (range, 6–74 months). The average maximum size of these 13 tumors was 5.7 × 5.8 × 4.8 cm.The mean operation time and blood loss were 458.5 minutes (range, 220–880 minutes) and 3,146.2 mL (range, 1,000–6,000 mL), respectively, with 4 of the 13 patients (30.8%) experiencing perioperative complications. Negative margins were achieved in all the 13 patients (100%). One patient experienced local recurrence (7.7%) and 1 patient experienced instrumentation failures. Interbody fusion was confirmed in 11 of the 13 patients (84.6%), with a median fusion time of 6.9 months. All of the 13 patients experienced varying degrees of mild postoperative neurological deficits owing to resection of the nerve roots affected by tumor invasion of the vertebrae. No vessel injury or postoperative neurological paralysis occurred, except 1 patient who had been completely paralyzed before surgery. Conclusions The rotation-reversion technique is an effective procedure for en bloc resection of selected thoracic and upper lumbar spinal tumors through the posterior-only approach.

BACKGROUND:Patients with osteoporotic compression fractures of the lumbar spine have varying degrees of changes in the sagittal parameters of the spine and pelvis,resulting in disequilibrium and rebalancing of the sagittal plane of the whole spine/lumbar spine.If the primary osteoporotic vertebral compression fracture is not treated promptly,it develops into an old osteoporotic vertebral compression fracture with nonunion over time. OBJECTIVE:To observe the effect of percutaneous vertebroplasty in nine patients with old osteoporotic lumbar compression fracture with nonunion. METHODS:A retrospective analysis was conducted on the clinical data of nine elderly patients with old osteoporotic lumbar compression fractures with nonunion treated in the Orthopedics Department of Shanghai Public Health Clinical Center from September 2018 to August 2022.All patients underwent revision treatment with percutaneous vertebroplasty and received regular anti-osteoporosis treatment and rehabilitation training.The lumbar spine X-ray plain film and three-dimensional CT test results were reviewed before discharge and during follow-up to evaluate the diffusion of bone cement.Visual analog scale score,lumbar Oswestry disability index score,and Roussouly classification were recorded before,after surgery and during follow-up. RESULTS AND CONCLUSION:(1)During postoperative follow-up,none of the 9 cases in this group experienced serious surgical complications such as nerve injury,infection,bone cement leakage,pulmonary embolism,and allergic shock,and no adverse reactions related to bone cement occurred.One patient died of respiratory failure due to COVID-19 infection 2 years after operation.(2)The visual analog scale score and Oswestry disability index score of postoperative pain in patients with recurrent vertebral fractures after percutaneous vertebroplasty were significantly lower than those before revision surgery.After the last follow-up percutaneous vertebroplasty revision surgery,the Roussouly classification of patients significantly improved.There was no statistically significant difference between the changes in vertebral body height during the last follow-up measurement and preoperative comparison.(3)These findings indicate that for patients with old osteoporotic lumbar compression fractures with nonunion,moderate injection of bone cement and effective dispersion of bone cement have a significant relieving effect on postoperative pain.Regular anti-osteoporosis and effective postoperative rehabilitation training can help patients improve their postoperative lumbar spine function.
