Inflammatory skin diseases(ISD)are characterized by persistent inflammatory cell infiltration and lingering and intractable skin lesions.At present,corticosteroids are the main drugs used in the treatment of ISD.However,due to the characteristics of recurrent and intractable ISD,long-term use of these hormone drugs may cause serious side effects in patients.In recent years,increasingly more studies are confirming that bee venom has significant anti-inflammatory,anti-apoptosis,anti-fibrosis,antibacterial,and other effects and could effectively treat ISD.In this paper,the main active components and anti-inflammatory mechanisms of bee venom are reviewed.The latest attempts to use bee venom for acne,atopic dermatitis,psoriasis,urticaria,and systemic lupus erythematosus are discussed,providing a reference for basic research and the clinical treatment of ISD.

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 study the impact and the mechanism of splenectomy combined with pericardial devascularization on cirrhotic livers.Methods:Serum samples and clinical data were collected preoperatively and postoperatively from 54 patients with cirrhosis who underwent splenectomy combined with pericardial devascularization from May 2013 to Oct 2014 at Beijing You’an Hospital, Capital Medical University. Changes in hepatic arterial and portal venous blood flow, liver function and fibroscan results were analyzed. The levels of nitric oxide (NO), endothelin-1 (ET-1), interleukin-6 (IL-6), hepatocyte growth factor (HGF), transforming growth factor-β1 (TGF-β1) and matrix metalloproteinase 1 (MMP1) were measured.Results:There were 31 males and 23 females, aged(45.48±10.21)years. Free portal vein pressure decreased significantly from (37.0±7.1) cmH 2O (1 cmH 2O=0.098 kPa) to (26.1±5.7) cmH 2O after surgery ( P<0.05). Significant increases in postoperative lumen diameter (4.0±1.0) mm vs (3.1±0.7) mm were observed, accompanied by increase in peak flow velocity and blood flow of the hepatic artery. Significant deductions in lumen diameter (11.9±2.0) mm vs (13.1±1.9) mm, accompanied by reduction of peak flow velocity and blood flow of the portal vein were observed following surgery (all P<0.05). The NO level was significantly elevated immediately after splenectomy and was subsequently remained at high levels. The ET-1 level decreased 2 days after surgery and became fluctuated at low levels. The IL-6 and HGF levels increased significantly 2 days after surgery and decreased gradually after 7 days and 1 month, respectively. The TGF-β1 and the MMP1 levels increased after surgery. The endotoxin level decreased significantly after surgery (all P<0.05). Conclusion:Splenectomy combined with pericardial devascularization induced hepatic blood flow restoration, hepatocyte regeneration and reversal of fibrosis in cirrhotic livers. Splenectomy has a protective effect on cirrhotic liver when combined with pericardial devascularization.

Objective:To explore the diagnostic value of quantitative 99Tc m-hydrazinonicotinamide(HYNIC)-prostate specific membrane antigen (PSMA) SPECT/CT in patients with prostate cancer. Methods:From November 2018 to March 2021, the data of 56 patients ((69.8±8.0) years) with clinically suspected prostate cancer, who had elevated radioactive uptake in prostate on 99Tc m-HYNIC-PSMA SPECT/CT images in Henan Provincial People′s Hospital, were retrospectively analyzed. According to the pathological results, patients were divided into prostate cancer group ( n=45) and non-prostate cancer group ( n=11). The xSPECT-QUANT software was used to quantitatively analyze the high uptake area of the prostate, and SUV max was measured. The independent-sample t test, Mann-Whitney U test, ROC curve and Spearman correlation analysis were used for data analysis. Results:The prostate cancer group had higher SUV max than non-prostate cancer group (10.79±5.96 vs 3.60±1.27; t=7.43, P<0.001). When SUV max≥6.46, the AUC of prostate cancer was 0.887, with the diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of 73.3%(33/45), 11/11, 100%(33/33), 47.8%(11/23), 78.6%(44/56), respectively. The SUV max of prostate cancer group was positively correlated with Gleason score ( rs=0.632, P<0.001). The SUV max of 29 patients with Gleason score≥8 was higher than that of 16 patients with Gleason score≤7 ( z=-3.89, P<0.001). There was no statistical difference in PSA level between patients with Gleason score≤ 7 and patients with non-prostate cancer ( z=-1.63, P=0.110), but the SUV max was significantly different ( z=-2.22, P=0.026). The SUV max of 23 patients with metastases was higher than that of 22 patients without metastasis (12.99±5.85 vs 8.50±5.28; t=2.69, P=0.010). ROC analysis showed that the AUC was 0.709; with SUV max≥13.02 as the threshold, the sensitivity for diagnosing prostate cancer metastases was 56.5%(13/23), the specificity was 86.4%(19/22), and the accuracy was 71.1%(32/45). Conclusions:The 99Tc m-HYNIC-PSMA SPECT/CT quantitative analysis is feasible in patients with prostate cancer. SUV max of 99Tc m-HYNIC-PSMA can be used in the diagnosis of prostate cancer, assessment of the malignancy and prediction of metastasis.

Objective To investigate the application technology and effect of Navien catheter in intracranial aneurysms embolization.Methods The clinical data of 15 patients with intracranial aneurysm treated with Navien catheter in Department of Neurosurgery of Yijishan Hospital Affiliated to Wannan Medical College from March to December 2016 were analyzed retrospectively. The extracranial segments of internal carotid arteries were seriously tortuous in all patients. The coaxial system was used during procedure. Whether the Navien catheter could be smoothly placed into the target artery or not was observed,and the coils or stent-assisted coils were used to embolize the intracranial aneurysms in the corresponding positions. The immediate embolization results were assessed by the Raymond grading. The intraoperative and postoperative complications were observed and the patients were followed up by imaging.Results All 15 patients had abnormal tortuosity of extracranial segments of internal carotid arteries. The Navien catheter was able to smoothly pass through the tortuous vessels and reach the desired position. The stent-assisted coil embolization was used in 9 patients,and the coil embolization was used in 6 patients. The success rate of the coil and stent placement technology was 100%. The stents were all accurately put in place without shift. According to the Raymond grading,the immediate embolization rate of aneurysms showed that 15 patients achieved Raymond gradeⅠ. One case developed internal carotid spasm during the procedure. The patient was improved after giving papaverine. Others did not have intraoperative complications,such as cerebral vasospasm,vascular dissection,in-stent thrombosis,and intraoperative aneurysm rupture. Five patients were followed up for 3 to 6 months with digital subtraction angiography (DSA). There was no recurrence of aneurysm and no in-stent stenosis and shift,No rebleeding or cerebral ischemia was observed.Conclusion Forpatients with severely tortuous in extracranial segments of internal carotid artery,using the Navien catheter may overcome artery tortuosity and other unfavorable factors of the patients and successfully reach the target vessel position,enable the embolization of intracranial aneurysms to be completed successfully.

Objective To investigate the influence of deep brain stimulation (DBS) at high frequency to the bilateral nucleus accumbens on morphine-induced conditioned place preference (CPP) and relapse behaviors during extinction phase in rats. Methods Twenty adult SD rats were employed in the experiment. Through stereotactic operation, outer electrode cannula was implanted into rats' bilateral nucleus accumbens. After 5 days of rest, the morphine-dependent rat model with CPP was established through intraperitoneal morphine injection (10 mg/kg). The rats, after being randomly divided into experimental group (morphine+DBS) and control group (morphine+sham DBS), were electrically stimulated using DBS circuits. Rats in the experimental group were given high frequency electrical stimulations while the control group was given sham stimulation. The CPP score of the two groups was recorded the day after stimulation until successful extinction and then the extinction time was compared between the two groups. After successful extinction the rats were given small dose of morphine to trigger relapse within 24 hours, and the CPP score was recorded and compared between the two groups.Results Compared with the control group (six days), the experimental group (26 days) had a longer extinction time. After relapse, the retention time within the drug-paired chamber of the experimental group was (357.01±192.72) s, obviously shorter than that of the control group ((704.91±181.35) s;t=2.370, P=0.034 6). Conclusion High frequency DBS to rats' bilateral nucleus accumbens can prolong extinction time but inhibit relapse behavior.

Objective To investigate the risk factors for influencing recrudescence after endovascular embolization of posterior communicating artery aneurysms.Methods From January 2014 to December 2014,71 consecutive patients (a total of 74 aneurysms) with posterior communicating artery aneurysm treated with endovascular treatment at the Department of Neurosurgery,Yijishan Hosptial of Wannan Medical College were enrolled retrospectively.The aneurysms were calculated as the number of cases (n=74).The aneurysms were divided into two groups according to whether they had recrudescence or not,including recurrent group (n=18) and non-recurrent group (n=56).The differences of the clinical data and aneurysm characteristics between the two groups were compared.Multivariate logistic regression was used to analyze the risk factors for recrudescence after endovascular embolization of posterior communicating artery aneurysms.Results Of the 74 patients with aneurysm,51 were treated with simple coil embolization and 23 were treated with stent-assisted coil embolization.All the coils were released satisfactorily.There were significant difference in the size of aneurysms and Raymond grade between the two groups (all P<0.01).The incidence of aneurysms with daughter cysts (55.6% [10/18] and the rate of non-stent-assisted coil embolization (88.9% [16/18]) in the recurrent group were significantly higher than those in the non-recurrent group (23.2% [13/56],62.5% [35/56]).The difference between the two groups was statistically significant (all P<0.05).There was no significant difference in other aneurysm features between the two groups (all P>0.05).After variable selection,the Raymond grade was referred to Raymond gradeⅠ.Multivariate logistic regression analysis showed that the non-stent-assisted coil embolization (OR,4.789,95%CI 1.207-19.009,P=0.026),Raymond grade Ⅱ (OR,12.326,95%CI 3.838-39.592,P<0.01),Raymond grade Ⅲ (OR,36.884,95%CI 2.892-470.454,P=0.005) were the independent risk factors for recrudescence after embolization of posterior communicating artery aneurysms.Conclusion Non-stent-assisted coil embolization,Raymond Ⅱ and Ⅲ may cause recrudescence of posterior communicating artery aneurysms.

Objective To investigate the level of phosphorylated high-molecular-weight neurofilament (pNF-H) after spinal cord injury (SCI), and explore the relationship between pNF-H and severity of SCI. Methods 20 Sprague-Dawley rats were equally divided into control group (group A), mild SCI group (group B), moderate SCI group (group C) and severe SCI group (group D). The level of pNF-H in serum, BBB score and remaining area of white matter were obtained at different time points. Results The level of serum pNF-H in groups B, C and D arrived at peaks 12 hours and 3 days after SCI, and there was significant difference among them (P<0.05). Both BBB score and remaining area of white matter 14 days after SCI negatively correlated with the level of pNF-H 3 days after SCI (r=-0.987 and r=-0.978, respective-ly). Conclusion The pNF-H increases twice after SCI in rats, and may be associated with the severe of SCI, which can be considered as a biomarker.

Objective To investigate the feasibility and effectiveness of endovascular treatment of posterior communicating artery aneurysm (PcoAA)in keeping the fetal posterior cerebral artery (FPCA) patency. Methods Form January 2014 to December 2015,14 patients with ruptured PcoAA enrolled retrospectively were treated with endovascular embolization. Six of them were treated with simple coil embolization,3 with stent-assisted coil embolization,3 with double catheter-assisted coil embolization,1 with stent-assisted coil embolization + double catheter technique,and 1 with Y-stent in Yijishan Hospital, Wannan Medical College. The immediate embolization rate of PcoAA (using Raymond grade),prognosis of the patients (the modified Rankin scale score at 6 months after procedure),complications,and imaging follow-up results were analyzed. Results The success rate of coil and stenting was 100% . All the stents were accurately released in place without displacement. The immediate Raymond grading of the aneurysms displayed that Raymond grade Ⅰ was in 8 cases,Raymond grade Ⅱ was in 4 cases,and Raymond grade Ⅲ was in 2 cases. All FPCA were kept patent. A coil protruded into internal carotid artery in one case during the procedure. Others did not have any complications,such as intraoperative cerebral vasospasm,in-stent thrombosis,and rupture. All 14 patients were followed up for 3 -24 months after procedure. Two had recurrence. Both were aneurysms embolized with coils only. No rebleeding and ischemic
complications were observed. The modified Rankin scale scores in 13 cases were 0 -2 at 6 months after procedure,1 was 4. Conclusions Endovascular embolization for the treatment of PcoAA and keeping FPCA patency are safe and feasible. A variety of endovascular treatment modalities are necessary in order to keep FPCA patency.
