OBJECTIVE: To investigate the effectiveness of Xuanshen Yishen Decoction (XYD) in the treatment of hypertension. METHODS: Hospital electronic medical records from 2019-2023 were utilized to emulate a randomized pragmatic clinical trial. Hypertensive participants were eligible if they were aged ⩾40 years with baseline systolic blood pressure (BP) ⩾140 mm Hg. Patients treated with XYD plus antihypertensive regimen were assigned to the treatment group, whereas those who followed only antihypertensive regimen were assigned to the control group. The primary outcome assessed was the attainment rate of intensive BP control at discharge, with the secondary outcome focusing on the 6-month all-cause readmission rate. RESULTS: The study included 3,302 patients, comprising 2,943 individuals in the control group and 359 in the treatment group. Compared with the control group, a higher proportion in the treatment group achieved the target BP for intensive BP control [8.09% vs. 17.5%; odds ratio (OR)=2.29, 95% confidence interval (CI)=1.68 to 3.13; P<0.001], particularly in individuals with high homocysteine levels (OR=3.13; 95% CI=1.72 to 5.71; P<0.001; P for interaction=0.041). Furthermore, the 6-month all-cause readmission rate in the treatment group was lower than in the control group (hazard ratio=0.58; 95% CI=0.36 to 0.91; P=0.019), and the robustness of the results was confirmed by sensitivity analyse. CONCLUSIONS XYD could be a complementary therapy for intensive BP control. Our study offers real-world evidence and guides the choice of complementary and alternative therapies.

ObjectiveTo investigate the feasibility of multiparametric MRI （mpMRI） combined with histogram analysis of apparent diffusion coefficient （ADC） in the assessment of patients with variant histology （VH） of urothelial carcinoma （UC）. MethodWe retrospectively analyzed the data of patients pathologically diagnosed with UC who underwent mpMRI in the First Affiliated Hospital of Sun Yat-sen University between March 2015 and March 2023. The patients were divided into VH group （urothelial carcinoma mixed with other histologies） and non-VH group （pure urothelial carcinoma） according to pathological results. We performed propensity score 1：1 nearest-neighbor matching on the two groups based on age and gender and 49 patients were included in each group. The regions of interest （ROIs） of the whole tumor were delineated manually by using ITK-SNAP software and Pyradiomics was applied to extract ADC histogram parameters. We compared the clinicopathological data， MRI morphological features and ADC histogram parameters between the groups. Multivariate logistic regression was used to identify independent risk factors and construct the prediction model. Receiver operating characteristic （ROC） curve analyses were performed to evaluate the diagnostic performance of these parameters for determining VH of UC. ResultsMRI morphological features including the lesion shape， vesical imaging-reporting and data system （Ⅵ-RADS）score， enhancement pattern and suspicious lymph node metastasis were markedly different between the two groups （all P < 0.05）. ADC _mean， ADC _median， ADC_25th， ADC_75th， ADC_10th and ADC_90th were significantly lower in patients with VH than those in non-VH group （all P<0.05）. Multivariate logistic regression analysis showed enhancement pattern， ADC_25th， ADC_75th and ADC mean were independent predictors （P < 0.05）. The combined model yielded the best predictive performance， with an area under the ROC curve （AUC） of 0.91 （95% CI： 0.83-0.96）. ConclusionsMpMRI combined with whole-tumor histogram analysis of ADC can serve as a reliable method for evaluating the presence of VH in UC， further to assist the clinical decision making.

Buxrugulosides A-E, four lignan glycosides (1-4) and a protocatechuate derivative (5) featuring a rare (N, N-diethyl)methyl amino group at aromatic rings, were obtained from the aerial parts of Buxus rugulosa, which is famous for treating coronary heart disease. Their structures including absolute configurations were elucidated by HRMS, 1D and 2D NMR, and by comparing their CD data with previous reports. Compound 1 was a rare sesquilignan, and all of these compounds were the first example of lignans with (N, N-diethyl)methyl amino group.

In recent years， the incidence of neurological diseases has been increasing year by year. To give full play to the advantages of traditional Chinese medicine （TCM） in the treatment of neurological disorders， identify the breakthrough point of integrating TCM with western medicine， and further standardize the clinical diagnosis and treatment of TCM， the China Association of Chinese Medicine organized neurologists in TCM and western medicine to carry out in-depth discussion on the neurological diseases responding specifically to TCM and integrated TCM and western medicine， such as stroke， headache， vertigo， multiple sclerosis， and epilepsy， aiming to formulate a well-recognized and integrated treatment protocol for TCM and western medicine and improve the efficacy of neurological disorders. Furthermore， the treatment suggestions of the corresponding diseases in TCM and western medicine were proposed to provide references for clinical practice and scientific research.

BACKGROUND: Knee osteoarthritis (OA) is a major cause of disability among the older adults. Few treatments are safe and effective. Moxibustion is commonly used in treating knee OA in Chinese medicine (CM). CO Laser moxibustion device is a substitute for traditional moxibustion, which mimics the effects of traditional moxibustion. More data are needed to support its application in knee OA. OBJECTIVE: ObjectiveThe trial aims to assess the effect and safety of CO laser moxibustion in patients with knee osteoarthritis compared with a sham control. METHODS: This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial. A total of 392 participants were recruited and assigned to the CO laser moxibustion group and sham laser moxibustion group with a 1:1 ratio at 6 outpatient clinics in Shanghai, China. Participants in both groups received treatment at the affected knee(s) at the acupuncture point Dubi (ST 35) and an Ashi point. There were 3 sessions per week for 4 weeks, and an additional 20-week follow-up. Primary outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain scores at week 4. Secondary outcomes were WOMAC function score, stiffness score and overall score, VAS pain, Short-Form heath survey (SF-36), and patients' global assessment. The serum levels of cytokines involved in progress of knee OA were explored. Safety was assessed during the whole trial. Masking effectiveness was assessed by both participants and treatment providers.This is a protocol for a multicenter, randomized, double-blind, placebo-controlled trial.

Objective To construct a human renal epithelial cell line HEK293T by CRISPR-Cas9-based site-directed knock-in of vascular endothelial growth factor 165 (VEGF165) gene, and avoid the off-target effect caused by lentivirus infection. Methods The VEGF165 expression vector with homologous arm (pUCm-T-VEGF165 plasmid) and the sgRNA expression vector [pSpCas9(BB)-2A-Puro-sgRNA plasmid] were designed and constructed based on the DNA sequence of the EZH2 gene, and then co-transfected into HEK293T cells. The expression of VEGF165 mRNA was detected by qPCR and the expressions of VEGF165 proteins were detected by Western Blot. Results The qPCR and Western Blot results showed that, comparing with the control, the pUCm-T-VEGF165 plasmid and pSpCas9(BB)-2A-Puro-sgRNA plasmid, the expression of the co-transfection plasmid were significantly increased, i.e. 3.42±0.30 vs. 1.02±0.21, 1.13±0.16 and 0.98±0.18 for the VEGF165 mRNA level (all P<0.01), and 1.13±0.16 vs. 1.02±0.06, 0.88±0.03 and 0.80±0.05 for the VEGF165 protein level (all P<0.01), respectively. Besides, the expression of EZH2 was significantly down-regulated, i.e. 0.14±0.06 vs. 1.08±0.11, 1.02±0.12 and 1.13±0.16 for the EZH2 mRNA level (all P<0.01), and 0.23±0.03 vs. 1.05±0.13, 0.91±0.04 and 0.81±0.06 for the EZH2 protein level (all P<0.01), respectively. This result showed that the VEGF165 was successfully inserted into the EZH2 genome, interfering the EZH2 expression. Conclusions VEGF165 gene can be successfully knocked into HEK293T cells by CRISPR/Cas9 system.

OBJECTIVETo evaluate the value of blood lactic acid (BLA) as a predictor for the severity and prognosis of neonatal shock.

METHODSA total of 326 neonates with shock were enrolled and divided into three groups based on the severity, namely mild group (n=147), moderate group (n=105), and severe group (n=74). BLA level was measured during and early after (about 6 hours later) fluid resuscitation, and lactate clearance rate (LCR) was calculated. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of BLA in neonatal shock.

RESULTSBLA level was high in all subjects prior to treatment, and was highest in the severe group and lowest in the mild group (P<0.01). BLA level was significantly higher among patients with septic shock than among those with hypovolemic, cardiogenic, and asphyxiating shock (P<0.05). BLA level was significantly reduced in patients in recovery after treatment (P<0.05). Mortality was significantly lower in patients with BLA level ≤4 mmol/L or LCR ≥10% than in those with BLA level >4 mmol/L or LCR <10% (P<0.01). BLA at 11.15 mmol/L had 100% sensitivity and 96.8% specificity in predicting severe shock. BLA at 10.65 mmol/L had 88.9% sensitivity and 74.1% specificity in predicting the prognosis (survival or dead) of newborns with shock.

CONCLUSIONSIn neonates with shock, arterial BLA level increases as the disease severity increases and is associated with prognosis, so it is a useful predictor of the severity and prognosis of neonatal shock.

OBJECTIVETo explore the clinical features and prognostic factors of pediatric acute lymphoblastic leukemia (ALL) in high-risk (HR) group.

METHODSA total of 421 children with ALL in the Children's Hospital of Soochow University from August 2008 to March 2013 were diagnosed and treated according to the Chinese Children Leukemia Group (CCLG)-2008 Protocol. Among different risk-groups, 148 cases were stratified into the low-risk group and 191 cases were included in the moderate-risk group. Eight-two patients of the high-risk group were analyzed retrospectively for their clinical features, 5-year event-free survival (EFS) rate and overall survival (OS) rate.

RESULTSThe median follow-up times of 82 patients were 64 months(3.0-76.3 months), 55 patient achieved complete remission(CR) after 1 cycle of induction chemotherapy(CR rate 67.1%), 25 patients relapsed(30.5%) mainly in very early and early relapse phases, significantly different from the low-risk group (P=0.013), 27 pateitns died(32.9%). The 5-year pEFS and pOS were 57.20% and 58.5%, respectively. Phor BCR/ABLand MRD>10on the 33rd day in the high-risk group were 2 main factors influencing EFS and OS according to single factor analysis. Phor BCR/ABLwas an independent prognostic factor, however, the MRD value on the 33rd day was not statistically significant differente by virtue of COX regression analysis.

CONCLUSIONThe clinical feature of children with ALL in high risk group display low induction CR rate, high recurrence rate and the lower 5-year pEFS. Phor BCR/ABLis regarded as an independent factor of poor prognosis.
