Objective:To explore the efficacy and safety of the modified VIALE-A regimen in the treatment of elderly (>75 years old) patients with intermediate or high risk myelodysplastic syndromes (MDS).Methods:A retrospective case series analysis was conducted. Clinical data were collected from 7 MDS patients aged >75 years who were continuously treated with the modified VIALE-A regimen (azacytidine 75 mg/m 2 per day from day 1 to day 7 + venetoclax 200 mg per day from day 8 to day 28) from May 2021 to August 2023, and the patients were diagnosed according to the World Health Organization 2016 staging criteria and were determined to be at intermediate or high risk according to the revised International Prognostic Scoring System. The patients' efficacy and common adverse reactions were analyzed, and the Kaplan-Meier method was used for survival analysis. Results:Of the 7 patients, 5 were female and 2 were male; the median age [ M ( Q1, Q3)] was 84 years old (80 years old, 90 years old). One patient failed the initial treatment, and the remaining 6 achieved complete remission or complete remission in bone marrow after induction therapy with the modified VIALE-A regimen in 1-2 courses. By the follow-up cut-off date of December 31st, 2023, the median follow-up was 10 months (5 months, 18 months) and the median overall survival time was 18 months (95% CI: 0-39 months). Grade 3-4 myelosuppression occurred in all 7 patients during the induction phase, with granulocytopenia lasting 7-10 d; Of the 64 courses of maintenance treatment, 54 (84%) had grade 1-3 myelosuppression; non-hematologic adverse reactions were mild; no treatment interruptions occurred in the cumulative 73 courses. Conclusions:The modified VIALE-A regimen is moderately efficacious in elderly patients with intermediate or high risk MDS, with controllable adverse reactions.

Background: and Purpose The eye-movement examination can be applied as a noninvasive method to identify multiple-system atrophy (MSA). Few studies have investigated eye movements during the early stage of MSA with predominant parkinsonism (MSA-P). We aimed to determine the characteristic oculomotor changes in the early stage of MSA-P. Methods: We retrospectively selected 17 patients with MSA-P and 40 with Parkinson’s disease (PD) with disease durations of less than 2 years, and 40 age-matched healthy controls (HCs).Oculomotor performance in the horizontal direction was measured in detail using videonystagmography. Results: We found that the proportions of patients with MSA-P and PD exhibiting abnormal eye movements were 82.4% and 77.5%, respectively, which were significantly higher than that in the HCs (47.5%, p<0.05). Compared with HCs, patients with MSA-P presented significantly higher abnormal proportions of fixation and gaze-holding (17.6% vs. 0%), without-fixation (47.1% vs. 0%), prolonged latency in reflexive saccades (29.4% vs. 5.0%), memory-guided saccades (93.3% vs. 10.0%), and catch-up saccades in smooth-pursuit movement (SPM, 41.2% vs. 0) (all p<0.05). Compared with those with PD, patients with MSA-P presented a significantly higher proportion of catch-up saccades in SPM (41.2% vs. 2.5%, p<0.001). Conclusions MSA-P presented the characteristic of catch-up saccades in SPM in the early stage, which may provide some value in differentiating MSA-P from PD.

Objective:This study aims to explore the impact of various clinical factors on the risk of polymyxin B induced DKI in patients.Methods:This is a single-center retrospective case-control study. A total of 139 patients receiving polymyxin B intravenous treatment in our hospital from January 1 to December 31, 2020 were collected. Baseline variables between polymyxin B induced DKI group and non-DKI group were compared using the Chi-square test or Fisher's exact test for categorical variables and the T-test or Wilcoxon rank sum test for continuous variables, as appropriate. Statistical analysis was performed using univariate and multivariate Logistic regression models, Logistic regression models, multivariate Logistic regression models, Kaplan Meier curve, as well as Log-Rank test.Results:Among a total of 139 patients receiving polymyxin B treatment, 49 cases have experienced DKI, 90 cases did not. The incidence of DKI was 35.25%. There was no statistical difference in general information of age, gender, and proportion of standard weight between the two groups. Among the related indexes of polycolistin B administration, the proportion of high daily dose [>25 000 U/(kg·d)] and the total dosage of medication in the DKI group were both significantly higher than that in the non-DKI group ( P< 0.05, respectively). Among the organ function indexes, there were significant differences in initial serum creatinine, blood urea nitrogen, uric acid, urinary occult blood and urinary specific gravity between DKI group and non-DKI group 48 hours before polymyxin B administration ( P< 0.05). Binary Logistic regression analysis suggested that daily dose and initial creatinine before medication were independent risk factors for DKI caused by polymyxin B ( P< 0.05). Kaplan-meier survival analysis showed that with the accumulation of Polymyxin B administration, the higher the daily dose of Polymyxin B was, the faster the DKI occurred (Log-Rank P= 0.0194). Conclusions:Using intravenous polymyxin B is associated with the risk of DKI, among which higher initial blood creatinine values and higher daily doses are independent risk factors for DKI.

Objective:To explore the relationship between soft markers found in the first trimester (11-13 + 6 gestational weeks) ultrasound screening and fetal adverse pregnancy outcomes. Methods:Single pregnancy fetuses were selected from the Multicenter Clinical Study of First Trimester Screening in China during August 2017 to August 2020. The types and detection rate of soft markers during the first trimester were compared. The correlation between positive soft markers and adverse pregnancy outcomes was analyzed by binary Logistics regression.Results:A total of 16 625 fetuses with complete follow-up outcomes were included in the group. Six hundred and seven ultrasonic soft markers were detected in 556 fetuses with positive soft markers during the first trimester, and the first four most frequently occurred were increased nuchal translucency (NT) (2.08%, 345/16 625), echogenic intracardiac focus (EIF) (0.94%, 156/16 625), hypoplasia of fetal nasal bone (0.20%, 34/16 625), single umbilical artery (SUA) (0.19%, 31/16 625). Among 556 fetuses, the incidence of adverse pregnancy outcome in fetuses with two or more positive soft markers was 32.50% (13/40), which was significantly higher than fetuses with single positive soft marker (11.05%, 57/516), and the difference was statistically significant (χ 2=5.055, P<0.001). The incidence of adverse pregnancy outcome in positive soft markers fetus associated with structural abnormalities was 80.77% (21/26), which was significantly higher than fetuses with isolated positive soft marker (12.08%, 64/530), and the difference was statistically significant (χ 2=90.310, P<0.001). Binary logistic regression analysis showed choroid plexus cyst (CPC), SUA, echogenic bowel (EB), absent/reversed a-wave of ductus venosus, hypoplasia of fetal nasal bone, increased NT, and EIF were closely related to the adverse pregnancy outcomes (all P<0.05). However, there were no significant correlations between tricuspid regurgitation (TR), pyelectasis (PYE) and fetal adverse pregnancy outcomes (all P>0.05). Conclusions:The ultrasonic soft markers during the first trimester are of great significance in predicting fetal adverse pregnancy outcomes. For multiple positive soft markers or positive soft markers combined with structural abnormalities, more attention should be paid to them and comprehensive evaluation is required to be carried out.

Rabdosia (Bl.) Hassk is a medicinal plant rich in enantiomers such as 15α-acetoxyl-6, 11α-epoxy-6α-hydroxy-20-oxo-6, 7-seco-ent-kaur-16-en-1, 7-olide and 15α-dihydroxy-6β-methoxy-6, 7-seco-6, 20-epoxy-1, 7-olide-ent-kaur-16-ene. It has high medicinal value and huge market potential, but the yield from wild Rabdosia (Bl.) Hassk species cannot meet the needs of marketization. Carrying out pollution-free cultivation of Rabdosia rubescens (Hemsl.) Hara and Rabdosia serra (Maxim.) Hara has become the most direct and effective measure to solve this problem in order to ensure the sustainable use of the resources of Rabdosia. This paper summarized a set of non- pollution cultivation system of R. rubescens and R. serra to achieve the"safe, effective, stable and controllable"target.

In order to reflect the research achievements of acupuncture on international academic community and study the acupuncture international discourse power from 2007 through 2017, we used text analysis software to analyze 5668 papers that focusing on acupuncture research in the recent 10 years. The results show that international acupuncture research trend has been formed, the research force diverges to the rest of the world with "China-America" as the center, and the study focuses on its sight and the interaction between China and foreign countries is good. Under the perspective of international discourse power, the construction of the national communication platform, the cultivation of academic centers and research fields, and the interaction with international research forces will enhance the quality of Chinese acupuncture research, and these will become an important task in enhancing the international discourse power of Chinese acupuncture.

OBJECTIVETo evaluate the efficacies of different treatments for recurrent cervical lymph nodes and the factors contributing to prognosis in patients with nasopharyngeal carcinoma after radiotherapy.

METHODSClinical data of 79 patients with nasopharyngeal carcinoma after radiotherapy were retrospectively analyzed, and all cases were diagnosed as having recurrent cervical lymph nodes by pathological examination. The factors including sex, age, the interval between completion of radiotherapy and recurrence, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor in the neck were analyzed for prognosis. Kaplan-Meier curves, Log-rank test and Cox's proportional hazards regression mode were used in the statistical analysis.

RESULTSThe median recurrence time was 26 months, and the 1- , 3- and 5-year overall survival rates were 77.9%, 53.4% and 39.7%. Cox's proportional hazards regression mode analysis indicated that age, rN stage, treatment methods, and the location relationship between recurrent lesion and primary tumor were significantly prognostic factors.

CONCLUSIONSNeck dissection is superior to re-radiotherapy in treatment of recurrent cervical lymph nodes in nasopharyngeal carcinoma after radiotherapy. The patients younger than 45 years old, in early rN stage and for recurrence in the center region of primary tumor have a better prognosis.

Objective To observe the clinical efficacy ofTiao Du Tong Ren (regulating the Governor Vessel and Unblocking the Conception Vessel) needling in treating post-stroke depression.Method Sixty patients with post-stroke depression were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened byTiao Du Tong Ren needling, while the control group was by ordinary acupuncture. The Hamilton Depression Scale (HAMD) was observed before and after intervention, and the clinical efficacies were compared between the two groups.Result The total effective rate was 93.3% in the treatment group versus 80.0% in the control group, and the difference was statistically significant (P<0.05). The HAMD scores were significantly changed in both groups after intervention (P<0.05). The change of HAMD score after intervention in the treatment group was markedly different from that in the control group (P<0.05).ConclusionTiao Du Tong Ren needling method is an effective approach in treating post-stroke depression.

Characteristics in pulse wave signals (PWSs) include the information of physiology and pathology of human cardiovascular system. Therefore, identification of characteristic points in PWSs plays a significant role in analyzing human cardiovascular system. Particularly, the characteristic points show personal dependent features and are easy to be affected. Acquiring a signal with high signal-to-noise ratio (SNR) and integrity is fundamentally important to precisely identify the characteristic points. Based on the mathematical morphology theory, we design a combined filter, which can effectively suppress the baseline drift and remove the high-frequency noise simultaneously, to preprocess the PWSs. Furthermore, the characteristic points of the preprocessed signal are extracted according to its position relations with the zero-crossing points of wavelet coefficients of the signal. In addition, the differential method is adopted to calibrate the position offset of characteristic points caused by the wavelet transform. We investigated four typical PWSs reconstructed by three Gaussian functions with tunable parameters. The numerical results suggested that the proposed method could identify the characteristic points of PWSs accurately.
