Objective:To analyze the effect of meridian scraping combined with thunder fire moxibustion in improving the motor function and hemorheology of patients with shoulder hand syndrome (SHS) after ischemic stroke, in order to provide reference for clinical intervention of SHS patients after ischemic stroke.Methods:A prospective study was conducted using a simple random sampling method to select SHS patients after ischemic stroke admitted to Shijiazhuang Hospital of Traditional Chinese Medicine from January 2020 to June 2023, and were randomly divided into two groups. The thunder-fire moxibustion group were given routine nursing and thunder-fire moxibustion therapy, and the combined group were additionally given scraping therapy along meridians on the basis of thunder-fire moxibustion group. The Upper Limb Fugl-Meyer Motor Function Assessment Scale (U-FMA) score, Visual Analogue Scale (VAS) score, Action Research Arm Test (ARAT) score, shoulder joint activity score, hemorheological indicators (hematocrit, plasma viscosity, platelet adhesion rate) and activities of daily living (Barthel Index), etc. were compared between two groups before and after intervention.Results:Finally, 86 patients with SHS after ischemic stroke were included, with 42 patients in the thunder-fire moxibustion group, including 25 males and 17 females, aged (59.37 ± 7.64) years; 44 patients in the combined group, including 24 males and 20 females, aged (59.52 ± 7.61) years. Before intervention, there was no statistical significance in U-FMA score, VAS score, ARAT score, shoulder joint activity score, hemorheology index level and Barthel Index between two groups (all P>0.05). After intervention, the U-FMA score, ARAT score and Barthel Index in the combined group were (48.21 ± 4.85), (40.22 ± 4.64), (56.43 ± 9.76) points, respectively, which were higher than (44.56 ± 4.23), (35.98 ± 4.37), (51.97 ± 8.31) points in the thunder-fire moxibustion group, the differences were statistically significant ( t =3.71, 4.36, 2.28, all P<0.05). The VAS score, shoulder joint mobility score, blood cell volume, plasma viscosity and platelet adhesion rate in the combined group were (2.44 ± 0.87) points, (1.23 ± 0.25) points, 0.44 ± 0.02, (1.35 ± 0.32) mPa·s, (53.56 ± 5.71)%, respectively, which were lower than (3.05 ± 0.99) points, (1.58 ± 0.22) points, 0.46 ± 0.02, (1.72 ± 0.36) mPa·s, (62.53 ± 5.94)% in the thunder-fire moxibustion group, the differences were statistically significant ( t values were 3.04-7.14, all P<0.05). Conclusions:Scraping along meridians combined with thunder-fire moxibustion therapy can achieve good intervention effect in patients with SHS after ischemic stroke, improve the upper limb motor function and hemorheology of patients, and enhance the activities of daily living.

Objective:To investigate the influence of cytochrome P450 2A6 (CYP2A6) gene polymorphisms on liver function injury in patients with hyperthyroidism treated with methimazole.Methods:The study selected 90 patients with hyperthyroidism who were treated with methimazole in the Department of Thyroid Surgery at the First Affiliated Hospital of Zhengzhou University from Sept. 2023 to Aug. 2024 as the research subjects. Based on the occurrence of liver injury, they were divided into a liver injury group ( n=36) and a non-liver injury group (n=54). Peripheral blood DNA was extracted from the patients, and the CYP2A6 gene genotypes (rs8192725, rs8192720, and rs28399433) were detected using the polymerase chain reaction (PCR) amplification method. The association between CYP2A6 gene polymorphisms and liver injury induced by methimazole treatment in hyperthyroidism was analyzed. Results:The comparison of genotype distribution frequencies at the rs8192725 locus between the liver injury group and the non-liver injury group showed a statistically significant difference ( P<0.05). The AG and GG genotypes at the rs8192725 locus were protective factors against liver injury in patients with hyperthyroidism (AG vs. AA, OR: 0.21; 95% CI: 0.08-0.57; P<0.05; GG vs. AA, OR: 0.24; 95% CI: 0.06-0.89; P<0.05; AG+GG vs. AA, OR: 0.22; 95% CI: 0.09-0.54; P<0.05). The frequency of the G allele of rs8192725 in the liver injury group was significantly lower than that in the non-liver injury group (G vs. A, OR: 0.36; 95% CI: 0.19-0.70; P<0.05), indicating that it is a protective factor for liver injury in hyperthyroid patients receiving methimazole treatment. Conclusions:The CYP2A6 gene polymorphism at the rs8192725 locus is associated with the occurrence of liver injury in patients with hyperthyroidism treated with methimazole. The G allele may be a protective factor against liver injury in patients with hyperthyroidism, suggesting that individualized treatment plans can be developed based on the patient's genotype.

Objective:To evaluate the efficacy of rhomboid inter-costal and sub-serratus (RISS) block with ropivacaine-dexmedetomidine-dexamethasone for analgesia after thoracoscopic lobectomy.Methods:This study was a prospective, randomized, double-blind, controlled trial. From January 2021 to November 2023, 46 American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients of either sex, undergoing elective video-assisted thoracoscopic lobectomy at the Second Affiliated Hospital of Nanjing Medical University, were selected and assigned into 2 groups ( n=23 each) using simple randomization: ropivacaine group (R group) and ropivacaine-dexmedetomidine-dexamethasone group (RDA group). RISS block was performed preoperatively, with 20 ml of the drug solution injected at the target points of the rhomboid-intercostal muscle and the serratus anterior-intercostal muscle. R group received 0.375% ropivacaine 40 ml, while RDA group received 40 ml of the mixture containing 0.375% ropivacaine, dexmedetomidine 1 μg/kg, and dexamethasone 8 mg. Postoperative analgesia was performed with oxycodone (When the patient′s numerical rating scale [NRS] score >4 in post-anesthesion care unit, oxycodone 2 mg was intravenously administered as needed until the NRS score <4, and then a patient-controlled analgesia pump was initiated). The time of the first postoperative analgesic requirement, NRS scores at rest and during coughing at 1, 3, 6, 12, 24 and 48 h postoperatively, cumulative consumption of oxycodone in the periods of 0-12 h, >12-24 h, and >24-48 h, time to first ambulation, and incidence of related adverse reactions within 48 h postoperatively were recorded. Results:Compared with R group, the time to the first analgesic requirement was significantly prolonged, the cumulative consumption of oxycodone in the first 0-12 h postoperatively was reduced ( P<0.001), and no statistically significant changes were found in the time to first ambulation, NRS scores at rest and during coughing, or the incidence of postoperative adverse reactions in RDA group ( P>0.05). Conclusions:RISS block using a combination of ropivacaine, dexmedetomidine and dexamethasone can significantly prolong block duration, reduce postoperative opioid analgesic consumption, and provide good safety for the patients undergoing thoracoscopic lobectomy.

Objective:To determine the median effective dose (ED 50) of oliceridine inhibiting the responses to the laryngeal mask airway insertion when combined with ciprofol in elderly patients. Methods:In this sequential trial, American Society of Anesthesiologists Physical Status classificationⅠ-Ⅲ elderly patients of either sex, aged ≥65 yr, with a body mass index of 18-30 kg/m 2, undergoing elective urological surgery under general anesthesia with laryngeal mask airway, were included in this study. Ciprofol 0.4 mg/kg was intravenously injected, the dose of oliceridine was determined by using modified Dixon′s up-and-down method (increment or decrement of 0.005 mg/kg), and the initial dose of oliceridine was 0.01 mg/kg. A positive response was defined as an increase in maximum mean arterial pressure or heart rate ≥20% within 3 min after inserting the laryngeal mask airway or occurrence of any one of these signs such as movement, coughing, frowning, mouth corner twitching, tearing, laryngospasm, or bispectral index value failing to drop below 60. The trial was terminated upon observing 7 positive-to-negative transition points, starting from the first occurrence of an alternation between positive and negative responses to laryngeal mask airway insertion. The ED 50 and 95% confidence interval of oliceridine inhibiting the responses to the laryngeal mask airway insertion was calculated when combined with ciprofol in elderly patients. Results:The ED 50 of oliceridine inhibiting the response to laryngeal mask airway insertion was 0.027 mg/kg, and the 95% confidence interval was 0.008-0.048 mg/kg when combined with ciprofol 0.4 mg/kg. Conclusions:The ED 50 of oliceridine inhibiting the response to laryngeal mask airway insertion is 0.027 mg/kg when combined with ciprofol 0.4 mg/kg in elderly patients.

Objective:To explore the optimization potential of clinical target volume (CTV) delineation proposed in the guidelines of the Oncology Group (RTOG), the Francophone Group of Urological Radiotherapy (GFRU), and the European Society for Radiotherapy and Oncology (ESTRO) based on prostate bed local occurrence patterns after radical prostatectomy identified using prostate-specific membrane antigen positron emission tomography (PSMA PET).Methods:A retrospective analysis was conducted on patients with local prostate bed recurrence after radical prostatectomy who underwent PSMA PET at the Department of Nuclear Medicine, Peking University First Hospital from September 2021 to February 2024. The central point of each recurrence was marked. A six-zone method was established based on prostate bed anatomy and the characteristics of cross-sectional imaging. Then, the positional relationships (within or outside) were recorded with respect to recurrences and CTV defined by the RTOG, GFRU, and ESTRO (CTV RTOG, CTV GFRU, and CTV ESTRO), followed the analysis of the recurrence rates and distribution characteristics of various zones. Results:A total of 63 patients with prostate bed recurrence after radical prostatectomy were enrolled in this study, including 97 recurrences. The recurrence rates in the six zones were as follows: 10% of zone 1, 22% of zone 2, 29% of zone 3, 2% of zone 4, 12% of zone 5a, 18% of zone 5b, and 7% of zone 6. Among these zones, zones 2 and 3 showed the highest and second-highest recurrence rates, respectively. CTV GFRU and CTV ESTRO completely covered zones 2 and 3, while CTV RTOG covered zone 2 completely and zone 3 partially. Zone 4, characterized by a low recurrence rate, was not covered by CTV GFRU and CTV ESTRO but was entirely covered by CTV RTOG. Zone 5a, with a recurrence rate of 12%, was completely covered by CTV RTOG but was partially covered by CTV GFRU and CTV ESTRO. The range of 1.3 cm in front of the posterior wall of the bladder covered all recurrences in zone 5a. Conclusions:For CTV delineation of the prostate cancer surgical bed, zone 4, the anterior half of the bladder above the pubic symphysis midpoint, should be contracted due to the low recurrence rate in this zone. In contrast, the anterior boundary above the pubic symphysis midpoint should extend to 1.3 cm in front of the posterior wall of the bladder to completely cover the recurrence zones.

Objective To explore the correlation between serum hypoxia-inducible factor-1α(HIF-1α)levels and cerebral microbleeds(CMBs)and cognitive impairment and to assess the predictive value of HIF-1α for CSVD-related cognitive impairment.Methods A total of 104 patients with CSVD who attended the Department of Neurology,First Affiliated Hospital of Xinxiang Medical University from June 2022 to November 2023 were enrolled.All enrolled patients were subjected to basic statistics,cranial nuclear magnetic resonance examination,cognitive function assessment,and serum HIF-1α test,and the number and location of CMBs were counted.Based on the above data the enrolled patients were grouped.The correlation between HIF-1α and cognitive function and CMBs was studied the influencing factors of CMBs and cognitive impairment were analyzed,and the predictive value of HIF-1α on the occurrence of cognitive impairment was evaluated.Results There were statistically significant differences in HIF-1α levels and cognitive function among different CMBs groups.Serum HIF-1α levels were significantly negatively correlated with overall cognitive function,visuospatial and executive function,attention,and delayed recall,and serum HIF-1α was positively correlated with the number of CMBs.HIF-1α may be a risk factor for CMBs and cognitive impairment associated with CSVD,and serum HIF-1α has potential in predict the cognitive impairment caused by CSVD.Conclusion Serum levels of HIF-1α were associated with the number of CMB and CSVD-related cognitive impairment,and serum levels of HIF-1α may have a predictive value for CSVD-related cognitive impairment.
