Objective:To observe the clinical efficacy of combined acupuncture and medication therapy in treating cerebral infarction in the acute stage and its impact on cerebral blood flow.Methods:A total of 160 patients with cerebral infarction were divided into 4 groups using the random number table method,with 40 cases in each group.Conventional treatment was given to all groups.Besides,the Chinese medication group received Tong Shen Fu Nao Wan;the acupuncture group received Xing Nao Kai Qiao(mind-refreshing and orifice-opening)needling therapy;the acupuncture-medication group received both Tong Shen Fu Nao Wan and Xing Nao Kai Qiao needling therapy.After 4 weeks of treatment,the clinical efficacy was assessed,and changes in the traditional Chinese medicine(TCM)symptom score and hemodynamics were compared among the four groups,as well as complications and adverse reactions.Results:After treatment,the acupuncture-medication group had a higher total effective rate compared to the other three groups(P<0.05).After the intervention,the National Institutes of Health stroke scale(NIHSS)score dropped in all groups(P<0.05)and was lower in the acupuncture-medication group than in the other three groups(P<0.05);all groups showed a decrease in the TCM symptom score(P<0.05),and the acupuncture-medication group was significantly lower than the other groups(P<0.05).After treatment,the blood flow velocity of the bilateral anterior cerebral artery(ACA),middle cerebral artery(MCA),and posterior cerebral artery(PCA)increased in every group(P<0.05),and the acupuncture-medication group had higher blood flow velocities compared to the other three groups(P<0.05).The acupuncture-medication group had the fewest number of complications among the four groups(P<0.05),and there was no statistical significance when comparing the adverse reactions among the groups(P>0.05).Conclusion:Compared to the separate use,the combined use of acupuncture and medication enhances the clinical efficacy,accelerates cerebral blood circulation,and boosts the recovery in treating cerebral infarction.

Objective To explore the feasibility of radiomics nomogram based on magnetic resonance diffusion weighted imaging for predicting the expression of Ki-67 in breast cancer.Methods A retrospective study was conducted on patients with breast cancer confirmed by surgery and pathology in the Second Affiliated Hospital of Guangdong Medical University.All patients were detected by Ki-67 expression staining,and then divided into group A(n=28,low-level expression of Ki-67)and group B(n=73,high-level expression of Ki-67).The apparent diffusion coefficient(ADC)graph was generated from diffusion weighted images,and the two groups were compared for radiomics features of ADC images and clinical data.The expression level of Ki-67 in breast cancer was predicted using the features of LASSO after dimensionality reduction,and a nomogram model was established,whose diagnostic efficiency was analyzed with receiver operating characteristic curve.Results No significant difference was observed in ADC value,age,carbohydrate antigen 199,carbohydrate antigen 153,carbohydrate antigen 125 and carcinoembryonic antigen between two groups(P>0.05).LASSO regression identified two radiomics features as predictors for the expression level of Ki-67 in breast cancer.The best tuning Lambda of LASSO was-0.125 690 135 478 682,and the included radiomics features for nomogram establishment were MinIntensity and Quantile95.The established nomogram had an area under ROC curve of 0.917,achieving a sensitivity of 91.7%and a specificity of 83.3%.Conclusion The expression of Ki-67 in breast cancer can be predicted based on the radiomics features of ADC images,which can provide a noninvasive detection method for evaluating the proliferation degree and treatment prognosis of breast cancer.

Objective:To investigate the value of digital medical 3D technology versus traditional 2D technology in the diagnosis and treatment of solid abdominal tumors in children. Methods:A total of 80 children with solid abdominal tumors who received surgical treatment guided by digital medical 3D technology at Guigang People's Hospital from January 2018 to January 2022 were included in the observation group. An additional 80 children with solid abdominal tumors who received surgical treatment guided by traditional 2D technology at the same hospital from January 2014 to December 2017 were included in the control group. Clinical efficacy was compared between the two groups.Results:The surgical time, intraoperative blood loss, postoperative exhaust time, postoperative hospital stay in the observation group were (111.8 ± 28.9) minutes, (26.8 ± 25.2) mL, (2.2 ± 1.2) days, (7.5 ± 1.4) days, respectively, which were significantly shorter or less than those in the control group [(193.1 ± 66.0) minutes, (86.2 ± 47.0) mL, (3.7 ± 0.9) days, (12.2 ± 3.5) days, t = 7.00, 6.88, 5.87, 7.53, all P < 0.05]. The complete surgical resection rate in the observation group was significantly higher than that in the control group [92.5% (74/80) vs. 81.3% (65/80), χ2 = 4.44, P < 0.05]. The incidence of complications in the observation group was significantly lower than that in the control group [6.3% (5/80) vs. 16.3% (13/80), χ2 = 4.00, P < 0.05]. Conclusion:The utilization of digital medical 3D technology in the surgical treatment of solid abdominal tumors in children can markedly decrease surgical time, reduce intraoperative blood loss, promote postoperative recovery, achieve a high surgical resection rate, and minimize postoperative complications.

Objective To establish a method to simultaneously determinate cobalt, nickel, arsenic, molybdenum, silver, cadmium and lead in blood and urine using inductively coupled plasma tandem mass spectrometry (ICP-MS/MS). Methods The blood samples were diluted 20 times with a mixed solution of nitric acid (0.10% V/V) and Triton X-100 (0.02% V/V). The urine samples were diluted 10 times with nitric acid (1.00% V/V). Yttrium-89, rhodium-103, and lutetium-175 were used as internal standards to decrease matrix interference, and either On-Mass mode or Mass-Shift mode was used to decrease mass spectrometry interference, with detection by ICP-MS/MS. Results The linear ranges of the seven elements were 0.100-10.000 μg/L, with the correlation coefficient >0.999 9. The detection limits for the seven elements in the blood and urine were 0.003-0.021 and 0.003-0.031 μg/L, respectively, and the minimum quantification limits were 0.009-0.064 and 0.009-0.094 μg/L, respectively. The recovery rates were 96.64%-102.90% and 96.34%-104.50% for the blood and urine, respectively. The within-run relative standard deviations (RSDs) were 0.32%-2.33% and 0.25%-2.31%, and the between-run RSDs were 1.07%-3.81% and 1.30%-3.62% for blood and urine, respectively. The samples were stable at 4 ℃ for at least 14 days. Conclusion ICP-MS/MS is a simple, sensitive, and accurate method for rapid detection of seven heavy metal elements in the blood and urine of occupational hazard-exposed workers.

Objective:To evaluate the therapeutic effects of Yufu ointment for acute radiation-induced skin injury. Methods:We enrolled a total of 104 patients with malignant tumors who developed acute skin injury of grade 2-3 during or after the first course of radiotherapy from June 2019 to February 2023. The observation group ( n=53) and control group ( n=51) received external application of Yufu ointment and Shirun Shaoshang ointment, respectively. We recorded the changes in the grade of skin injury and associated symptoms (such as pain, itching, and burning sensation) and healing speed and time for the two groups. Results:A total of 102 patients completed the study, with 53 cases in the observation group and 49 cases in the control group. The incidence rate of moisture skin lesions in the observation group was significantly lower than that in the control group (62.26% vs. 83.67%, P<0.05). The healing speed of moisture skin ulcerations was significantly faster in the observation group than in the control group (1.67 cm 2/d vs. 0.55 cm 2/d, P<0.05). The observation group had a significantly shorter time to skin injury healing than the control group (10.40 d vs. 14.41 d, P<0.05), significantly different for skin injury of grade 2 (10.21 d vs. 17.57 d, P<0.05) but not for skin injury of grades 2.5 and 3 ( P>0.05). Regarding clinical symptoms, both groups experienced significant reductions in pain and burning sensation scores after treatment ( P<0.05); the grade of itching was significantly decreased for the observation group ( P<0.05), but had no significant change for the control group after treatment ( P>0.05). Conclusions:Yufu ointment can significantly alleviate secondary damage for patients with acute radiation-induced skin injury, by accelerating the healing process and relieving symptoms such as pain, itching, and burning sensation with good tolerability, which deserves further promotion.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective To investigate the predictive value of vitamin D,sex hormones and their receptors in the development and regression of male patients with clinical isolated syndrome(CIS).Methods A total of 40 male CIS patients were included in the CIS group and 30 healthy subjects matched in age and long-term res-idence were included in the control group.The levels of vitamin D[1,25(OH)2D2 and 1,25(OH)2D3]inpe-ripheral blood of the included individuals and the first relapsed multiple sclerosis patients(MS group)were detected by ultra-high-performance liquid chromatography-tandem mass spectrometry.The levels of testoster-one(T),progesterone(P),and estradiol(E2)in peripheral blood were detected by electrochemiluminescence.Estrogen receptor(ERα,ERβ),androgen receptor(AR)and vitamin D receptor(VDR)levels in lymphocyte supernatant were detected by enzyme-linked immunosorbent assay(ELISA).Results After a median follow-up of 31.5 months,29 patients(72.5％)with CIS were converted to multiple sclerosis.Compared with pa-tients with non-recurrent CIS patients,patients with multiple sclerosis had a younger age of onset and were prone to positive oligoclonal bands.Compared with HC group,vitamin D levels were reduced in CIS patients,and the difference was statistically significant(P＜0.05).When CIS patients reverted to multiple sclerosis,se-rum levels of E2,ERα,and ERβ were elevated compared with those before relapse,and the levels of testosteroneand AR were decreased,and the difference was statistically significant(P＜0.05).Correlation analysis showed no correlation between peripheral blood levels of vitamin D,sex hormones and their receptors and EDSS in CIS patients.Conclusion Male CIS patients with younger onset age and positive oligoclonal bands are prone to transition to multiple sclerosis.The decrease of vitamin D level may be associated with the onset of male CIS.Vitamin D,sex hormones,and their receptors have no predictive value in the conversion of CIS to multiple sclerosis.
