Objective To investigate the prevalence of substantia nigra(SN)hyperechogenicity in patients with Parkinson's disease(PD)using transcranial ultrasound(TCS),identify the associated influencing factors,and construct a predictive model.Methods A retrospective analysis was conducted on 101 PD patients admitted to Chengde City Central Hospital between August 2022 and July 2024.All patients underwent TCS examination to detect SN hyperechogenicity.Based on TCS findings,patients were categorized into case group(SN hyperechogenicity,stagesⅢ-V)and control group(normal SN echogenicity,stagesⅠ-Ⅱ).The prevalence of TCS-detected SN hyperechogenicity in PD patients was evaluated,and the clinical and laboratory data between two groups were compared.The risk factors for SN hyperechogenicity in PD patients were identified using multivariate Logistic regression,and a regression equation model of Logit(P)was established based on the results of multivariate analysis.The established model was validated by the Hosmer-Lemeshow goodness-of-fit test and the likelihood ratioχ2 test.Receiver operating characteristic(ROC)curve was constructed to evaluate the predictive accuracy of the model for SN hyperechogenicity in PD patients,and the area under the curve(AUC)was calculated.Results Among 101 PD patients,34(33.66%)exhibited SN hyperechogenicity.Compared with control group,case group had higher percentages of olfactory dysfunction,sleep disorders and H-Y stage≥Ⅲ(P<0.05),and lower levels of serum copper and ceruloplasmin(P<0.05).Multivariate Logistic regression analysis identified olfactory dysfunction,sleep disorders,H-Y stage≥Ⅲ,decreased serum copper and reduced ceruloplasmin as independent risk factors for SN hyperechoicity in PD patients(OR=2.168,2.008,2.063,2.300,1.921,respectively;P<0.05).The predictive model was formalized as Logit(P)=-9.233+olfactory dysfunction×0.774+sleep disorders×0.697+H-Y stage≥Ⅲ×0.724+decreased serum copper×0.833+reduced ceruloplasmin×0.653.ROC analysis showed that when Logit(P)>13.00,the AUC value was 0.876(95%CI:0.795-0.933),with a sensitivity of 73.53%and a specificity of 82.09%.Conclusion The phenomenon of TCS-detected SN hyperechogenicity is severe in PD patients,and its occurrence was associated with olfactory dysfunction,sleep disorders,H-Y stage≥Ⅲ,decreased serum copper and reduced ceruloplasmin,and the predictive model incorporating these factors demonstrated excellent predictive value.

Objective:To investigate the efficacy of endoscopic sclerotherapy for internal hemorrhoids and its effects on patients' bowel function.Methods:A total of 111 patients who received endoscopic sclerotherapy at Xi'an No. 3 Hospital from September 2019 to August 2020 were retrospectively included in this study. Clinical efficacy, postoperative complications, perianal discomfort, and abnormal defecation were compared among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at 1, 4, 8, 12 weeks, and 6 months after surgery.Results:After 6 months of follow-up, the overall response rate was 77.48% (86/111), and the cure rate was 77.17% (79/111). The response rate and cure rate for rectal bleeding were 83.75% (67/80) and 80.00% (64/80), respectively. The response rate and cure rate for prolapse were 82.46% (47/57) and 75.44% (43/57), respectively. There were no statistically significant differences in the response rates and cure rates for rectal bleeding and prolapse symptoms among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids at each follow-up time point (all P>0.05). Among the 111 patients, 27.93% (31/111) experienced perianal discomfort, and 40.54% (45/111) reported abnormal defecation. The incidences of perianal discomfort and abnormal defecation were not statistically significant among patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids (both P>0.05). In patients with gradeⅠ and Ⅱ internal hemorrhoids, perianal discomfort symptoms began to improve 4 weeks after surgery, while symptoms of abnormal defecation started to improve 1 week after surgery. Conclusions:Endoscopic sclerotherapy has a good clinical efficacy for rectal bleeding and prolapse symptoms in patients with grade Ⅰ, Ⅱ, and Ⅲ internal hemorrhoids. Additionally, it improves perianal discomfort and abnormal defecation by identifying the anal canal transition zone in patients with internal hemorrhoids.

Objective To compare the efficacy,acceptability and safety of a low-volume magnisium sodicum potassium sulfate oral sulfate solution(OSS)with polyethylene glycol(PEG)electrolytes powder in bowel preparation for colonoscopy.Methods A prospective,single-blinded and single-center cohort study was conducted.The ambulatory and hospitalized 1 037 patients who underwent colonoscopy from April 2023 to January 2024 were enrolled.Participants were divided into OSS group(639 cases)and PEG group(398 cases),according to the bowel cleansing drugs taken orally.After propensity score matching(PSM),each group included 385 cases.The success rate of bowel preparation,scores of Boston bowel preparation scale(BBPS),medication taste,patients'satisfaction and the occurrence of adverse events were compared.Results The success rate of bowel preparation in the OSS group was 96.4％(371/385),higher than the 91.7％(353/385)in the PEG group,and the difference was statistically significant(P＜0.05).The total and segmented BBPS scores of the OSS group were higher than those of the PEG group,the differences were statistically significant(P＜0.05).The medication taste and patients satisfaction of the OSS group were significantly better than those of the PEG group,the differences were statistically significant(P＜0.05).There was no statistically significant difference in incidence of adverse reactions between the two groups(P=0.800).Conclusion Compared to PEG,OSS has a better intestinal cleaning effect,medication taste,and patients satisfaction.In addition,OSS has security that is not inferior to PEG.

ObjectiveTo explore the clinical application law and provide literature support and development ideas for the modern application of fresh Plantaginis Herba. MethodThe literature about the application of fresh Plantaginis Herba was retrieved from the fifth edition of Chinese medical dictionary， China national knowledge infrastructure （CNKI）， VIP， Wanfang data， and Chinese medical journals and analyzed. ResultFresh Plantaginis Herba appeared frequently in ancient books， with the effects of clearing heat， cooling blood， promoting urination， and relieving stranguria. It was used for the treatment of stranguria， urine retention， bloody urine， sore and carbuncle， epistaxis， red and swelling eye， suppurative inflammation in the throat， and gynecological and pediatric diseases. According to modern medical publications， fresh Plantaginis Herba is mainly used to treated diseases in the kidney， five sense organs， spleen， stomach， lung， liver， gallbladder， and skin and gynecological and pediatric diseases. Specifically， it is mainly used to treat the syndrome of dampness and heat in kidney and skin diseases caused by the accumulation of dampness and heat toxin， with the effects of clearing heat， removing toxin， promoting urination， and relieving stranguria. Since ancient times， there have been reports of using fresh Plantaginis Herbausing for food and health care. ConclusionFresh Plantaginis Herba is widely used in clinical practice and has a high medical value and economic value. However， its modern application lags behind， so it is necessary to promote the development of fresh Plantaginis Herba from the aspects of medicinal material production， storage， transportation， preparation research and development， and clinical application.

【Objective】 To investigate the frequency of platelet antibodies in voluntary blood donors and patients in Zhongshan, Guangdong Province, and to study the specificity and cross-matching of platelet antibodies. 【Methods】 Platelet antibodies of blood donors and patients were screened by solid-phase immunoadsorption (SPIA), rechecked by flow cytometry (FCM), and antibody specificity was identified by PakPlus enzyme immunoassay, and platelet cross-matching was simulated by SPIA. 【Results】 A total of 1 049 blood donor samples and 598 patient samples were tested, with 6 (0.57%) and 49 (8.19%) samples positive for SPIA,respectively(P<0.05); In SPIA positive samples, the positive concordance rate of FCM in blood donors and patients was 100% vs 95%, and that of enzyme immunoassay was 100% vs 88%. Among the initial screening positive samples of blood donors, 5 were anti-HLA Ⅰ antibodies, accounting for 83%, and 1 was anti CD36 antibody, accounting for 17%, with an incidence rate of 0.10%. Among the 14 samples of enzyme immunoassay positive patients, 2 were anti-GP Ⅱb/Ⅲa, 1 was anti-GP Ⅱa/Ⅱa, 8 were anti HLA Ⅰ, and 3 were mixed antibodies (HLA Ⅰ, GP Ⅱb/Ⅲa, GP Ⅰa/Ⅱa). According to the types of antibodies, HLA Ⅰ antibodies were the most common, accounting for 65% (11/17), followed by HPA related anti GP, accounting for 35% (6/17). The majority of patients had a platelet antibody positive typing rate below 30%, accounting for 71.4% (10/14). 【Conclusions】 The positive rate of platelet antibody of patients in Zhongshan area is significantly higher than that of voluntary blood donors, and most of them are anti-HLA Ⅰ and anti-GP, and the incidence of anti-CD36 is extremely low. Therefore, it is necessary to establish a known platelet antigen donor bank, and at the same time, carry out platelet antibody testing and matching of patients, which is helpful to solve the issue of platelet transfusion refractoriness.
