ObjectiveThe central symptom of Parkinson’s disease (PD) is impaired motor function. Beta-band electrical activity in the motor network of the basal ganglia is closely related to motor function. In this study, we combined scalp electroencephalography (EEG), brain functional network, and clinical scales to investigate the effects of beta burst-period neural electrical activity on brain functional network characteristics, which may serve as a reference for clinical diagnosis and treatment. MethodsThirteen PD patients were included in the PD group, and 13 healthy subjects were included in the healthy control group. Resting-state EEG data were collected from both groups, and beta burst and non-burst periods were extracted. A phase synchronization network was constructed using weighted phase lag indices, and the topological feature parameters of phase synchronization network were compared between the two groups across different periods and four frequency bands. Additionally, the correlation between changes in network characteristics and clinical symptoms was analyzed. ResultsDuring the beta burst period, the topological characteristic parameters of phase synchronization network in all four frequency bands were significantly higher in PD patients compared to healthy controls. The average clustering coefficient of the phase synchronization network in the beta band during the beta burst period was negatively correlated with UPDRS-III scores. In the low gamma band during the non-burst period, the average clustering coefficient of phase synchronization network was positively correlated with UPDRS and UPDRS-III scores, while UPDRS-III scores were positively correlated with global efficiency and average degree. ConclusionThe brain functional network features of PD patients were significantly enhanced during the beta burst period. Moreover, the beta-band brain functional network characteristics during the beta burst period were negatively correlated with clinical scale scores, whereas low gamma-band functional network features during the non-burst period were positively correlated with clinical scale scores. These findings indicate that motor function impairment in PD patients is associated with the beta burst period. This study provides valuable insights for the diagnosis of PD.

OBJECTIVE To explore the clinical risks and monitoring essentials associated with tonifying Chinese patent medicine. METHODS The varieties of tonifying Chinese patent medicines listed in the National Basic Drug List （2024 edition） were counted. Package inserts were collected using software such as “Dingxiangyuan” and then classified and organized according to criteria such as “drug name”“ingredients”“contraindications”“precautions”“drug interactions”. The names of traditional Chinese medicine （TCM） decoction pieces were standardized in accordance with the Chinese Pharmacopoeia （2020 edition） and other relevant standards； literature was reviewed to compile information on TCM decoction pieces that required caution/were contraindicated in special populations， as well as tonifying Chinese patent medicines and their related clinical applications. Then， a database for tonifying Chinese patent medicines was ultimately established by relying on the hospital’s internal information system， so as to conduct an in-depth exploration of the clinical usage risks and key monitoring points of tonifying Chinese patent medicines. RESULTS A total of 222 tonifying traditional Chinese medicines were evaluated. Contraindications or requirements for cautious use were identified in 91 （40.99%） for hepatic or renal impairment， 9 （4.05%） for hypertension， and 8 （3.60%） for pediatric patients， and 109 （49.10%） were designated as contraindicated or requiring caution for athletes. CONCLUSIONS Although tonifying Chinese patent medicines are indicated for deficiency patterns， their use is accompanied by measurable clinical risk， especially in individuals with hepatic or renal compromise who are prone to adverse reactions.

Purpose To explore the value of CT-based radiomics in the preoperative prediction of lymphatic invasion of node-negative gastric cancer,and to construct a nomogram combined with clinical variables.Materials and Methods The clinical and CT imaging data of 173 gastric cancer patients with lymph node negative and pathologically confirmed gastric cancer in the Sir Run Run Shaw Hospital from January 2019 to June 2021 were retrospectively analyzed.A total of 60 cases with lymphovascular invasion(LVI)positive patients and 113 cases with LVI negative patients were included,and randomly divided into train cohort(n=121)and test cohort(n=52)at 7∶3.Based on the train cohort,the clinical model,the radiomics model,the fusion model were constructed and verified in the test cohort.Clinical data and conventional CT features included age,gender,tumor marker,tumor location,tumor morphology,enhancement range,etc.The clinical significant variables were selected through univariate and multivariate analysis to establish the clinical model.The tumor regions of interest were segmented and radiomics features were extracted by using the 3D-Slicer software.Key features were screened through least absolute shrinkage and selection operator regression analysis,and then the radiomics model was constructed with random forest algorithm,and converted to random forest score(RF score).The fusion model was constructed via combining clinical significant variables and RF score,and visualized as a nomogram.The receiver operator characteristic curve and area under curve(AUC)were used to evaluate the prediction performance of the models.Decision curve analysis was used to calculate the clinical practicability.Results The radiomics model was superior to the clinical model.The radiomics model AUC of the train cohort and the test cohort were 0.872(0.810 to 0.935)and 0.827(0.707 to 0.947),the clinical model AUC were 0.767(0.682 to 0.852)and 0.761(0.610 to 0.913).The nomogram further improved the predictive efficiency,the AUC in train cohort and test cohort reached 0.898(0.842 to 0.953)and 0.844(0.717 to 0.971),respectively.Decision curve analysis demonstrated clinical benefits of nomogram.Conclusion The radiomics model can be used to preoperatively predict LVI of node-negative gastric cancer.The nomogram can further improve the prediction efficiency.

Objective:To advance the understanding of posterior reversible encephalopathy syndrome (PRES) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The medical history, diagnosis and treatment process, laboratory examination and imaging examination results of a patient who developed PRES after undergoing allo-HSCT at Changhai Hospital of Naval Medical University in November 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 33-year-old woman, and she was admitted to the hospital with 17 years of diagnosis of aplastic anemia, 1 month after sibling-matched allo-HSCT, with low-grade fever for 1 week. On the 7th day of hospitalization, the patient experienced a sudden onset of seizures. After combining findings from cranial magnetic resonance imaging (MRI) and other relevant examinations, organic brain lesions were ruled out, and PRES was considered. The patient's condition improved after receiving antihypertensive, antiepileptic, anti-infection, and other appropriate treatments. A follow-up cranial enhanced MRI was performed 3 months after the onset of symptoms revealed the disappearance of lesions.Conclusions:PRES after allo-HSCT has the potential to yield favorable outcomes when it is promptly diagnosed and treated.

Objective:To explore the early effects and safety of using a hybrid fixation strategy with 3D-printed porous tantalum metal augments to reconstruct substantial bone defects in complex primary total knee arthroplasty (TKA).Methods:A retrospective analysis was performed on the clinical data from August 2019 to September 2023, encompassing 20 patients (21 knees) with significant bone loss who underwent hybrid fixation with 3D-printed porous tantalum augments. The procedures were conducted at two medical centers: the First Affiliated Hospital, School of Medicine, Zhejiang University (11 cases) and Xiangya Hospital of Central South University (9 cases). The study cohort comprised 6 males (6 knees) and 14 females (15 knees), with a mean age of 61.05±11.23 years (range, 42-80 years). The distribution of cases was 7 on the left side and 14 on the right side. All cases were categorized as type 3 according to the Anderson Orthopaedic Research Institute (AORI) classification system. The cohort included 19 unilateral and 1 bilateral case, with 5 involving complex primary replacements (3 with Charcot arthropathy, 1 with syphilitic arthropathy, and 1 with severe valgus deformity) and 16 revision surgeries (13 for aseptic loosening and 3 for infection). Preoperative assessments included routine CT scans and digital three-dimensional reconstructions to identify large metaphyseal defects exceeding 50% of the metaphyseal area or those thicker than 10 mm. For such defects, 3D-printed standardized porous tantalum augments were implemented. In cases of extensive cavitary bone defects or severe metaphyseal defects where the medial and lateral defects collectively exceeded 80% of the metaphyseal region or where the residual bone stock was insufficient for screw fixation of standardized augments, 3D-printed personalized custom-made porous tantalum augments were employed for hybrid fixation and repair. Comparative analyses were conducted on pre- and postoperative imaging data (prosthesis positioning and complications), knee range of motion (ROM), visual analogue scale (VAS) for pain, and Knee Society score (KSS).Results:Of the cases, 17 were repaired using standardized 3D-printed porous tantalum augments, while 4 underwent repairs with customized augments for hybrid fixation. Follow-up averaged 26.5±15.0 months (range, 12-62 months). There was a significant increase in knee ROM, improving from 72.8°±31.9° preoperatively to 113.2°±6.8° at 12 months postoperatively ( P<0.05). VAS scores decreased from 6.6±1.4 preoperatively to 2.5±1.0 at 12 months postoperatively ( P<0.05). Similarly, KSS improved from 52.8±6.4 preoperatively to 80.7±7.9 at 12 months postoperatively ( P<0.05). There were no incidences of prosthesis displacement, poor bone integration, or postoperative infections. Conclusion:The hybrid fixation strategy employing 3D-printed porous tantalum augments has been found to be effective in addressing significant bone defects in TKA. The follow-up results indicate a satisfactory biological integration of the porous tantalum metal augments with the host bone, which has resulted in substantial improvements in pain relief and knee joint functionality.

Evidence mapping was performed to review the clinical trials and systematic reviews about the treatment of hyperlipidemia with Chinese patent medicines in recent ten years. A total of 387 clinical studies and 18 systematic reviews/Meta-analysis involving 45 Chinese patent medicines commonly used in the treatment of hyperlipidemia in recent ten years were retrieved from Chinese and English academic publication databases. The article information was extracted by reading the abstract and full text, and the evidence of publication trend, combined medication, intervention course, complications, and outcome indicators was sorted out. The Cochrane risk-of-bias assessment tool was used to evaluate the quality of some randomized controlled trial(RCT), and the research results were presented by figures combined with tables. The Chinese patent medicines mostly mentioned included Xuezhikang Capsules, Yindan Xinnaotong Capsules, Hedan Tablets, Pushen Capsules, and Compound Danshen Dropping Pills. The outcome indicators included blood lipid levels(total cholesterol, low-density lipoprotein, etc.), clinical efficacy(markedly effective, effective, and ineffective), adverse reactions(mainly including gastrointestinal reactions), hemorheological indicators, and liver and kidney functions. The available studies generally had small sample sizes, short period, and insufficient attention to traditional Chinese medicine(TCM) syndromes. The RCT and systematic reviews/Meta-analysis generally had low quality, and thus the results had low reliability. Nevertheless, the studies demonstrated a heightened focus on adverse reactions, diverse combined intervention measures, and varied options for addressing different complications. It is recommended that the clinical research on Chinese patent medicines for hyperlipidemia should strive to improve research quality, standardize research protocols, and devote greater attention to TCM syndromes, thereby enhancing the influence and effectiveness of these medicines.

Objective: To evaluate the effectiveness of Bian stone warming and ironing combined with aromatherapy on postpartum urinary retention among lying-in women with painless delivery, so as to provide the reference for preventing postpartum urinary retention after painless delivery. Methods: Lying-in women who underwent painless delivery in the Hangzhou Women' s Hospital were randomly assigned into the intervention and control group. Participants in the intervention group were given Bian stone warming and ironing combined with essential oil aromatherapy, while participants in the control group were given routine nursing care. The first postpartum urination and urinary retention were recorded, nursing satisfaction was investigated using Newcastle Satisfaction with Nursing Scale, the quality of life was evaluated using The World Health Organization Quality of Life-BREF, and these indicators were compared between the two groups. Results: There were 92 participants in the intervention group, with a mean age of (26.51±1.31) years and mean gestational age of (38.11±0.55) weeks, and 86 participants in the control group, with a mean age of (26.61±1.24) years and mean gestational age of (38.28±0.72) weeks. There was no statistically significant difference in the general data between the two groups (P>0.05). The time of first urination in the intervention group was shorter than that in the control group [(2.91±1.02) h vs. (3.76±1.68) h], the first postpartum urine volume was more than that in the control group [(160.56±21.03) mL vs. (142.43±18.42) mL], the residual urine volume of the bladder after the first urination was less than that in the control group [(73.20±17.03) mL vs. (85.46±20.24) mL], the incidence of urinary retention was lower than that in the control group (3.26% vs. 10.47%), nursing satisfaction was higher than that in the control group, and the increase in scores of all dimensions of quality of life was greater than that in the control group, with statistically significant differences (all P<0.05). Conclusions Bian stone warming and ironing therapy combined with aromatherapy may effectively reduce the incidence of postpartum urinary retention, and improve nursing satisfaction and quality of life among lying-in women after painless delivery.

The main sources of natural drugs include various biological species such as plants, animals, and microorganisms. The accurate identification of these species is the bedrock of natural drug development. We propose a novel method of species identification in this paper: analysis of whole-genome (AGE), a molecular diagnostic method used to identify species by finding species-specific sequences from the whole genome and precisely recognizing the specific target sequences. We elaborate that the principle for species identification based on AGE is that the genome sequences of diverse species must differ and divide the implementation strategy of the method into two levels of research and application. Based on our analysis of its characteristics, the method would have the potential advantages of reliable principle, high specificity, and wide applicability. Moreover, three crucial concerns related to building method systems including genome acquisition, bioinformatics analysis, and database construction, are further discussed. In summary, we offer theoretical underpinnings and methodological guidance for the development of bioinformatics software and commercial kits, indicating AGE has great application potential in objects, subjects, and industries.

OBJECTIVE: To retrospectively study medium term follow up outcomes effects of effect of bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients. METHODS: Total of 32 elderly patients with the osteoporotic intertrochanteric fractures were treated with bio-lengthend stem hemiarthroplasty from Jan. 2016 to Jan. 2019 including 14 males and 22 females, aged from 85 to 95 years old with an average of (89.5±4.5) years old. According to classification of Evans, there were 12 cases with type Ⅲ, 11 with type Ⅳ and 9 with type Ⅳ. The time from injury to operation ranged from 0.5 to 9 days with an average of (4.5±3.9) days. The operation time, blood loss and postoperative complications were analyzed. Functional outcome was assessed by Parker Palmer mobility score(PPMS) and Harris hip score. RESULTS: Four patients died within one year after operation, and the mortality was 12.5%. The follow up time for the rest 28 patients ranged from 24 to 60 months with an average of (28.5±4.5) months. The mean operative time was (54.2±22.5) min;the mean blood loss (hidden blood loss+obvious blood loss) was (450±140) ml;the first weight bearing was (3.35±1.35) days. No perioperative death occurred. PPMS were(6.63±1.25), (6.94±1.18), (7.11±0.83), (7.32±1.11) and Harris scores were(67.85±6.19), (71.42±5.57), (73.41±5.62), (77.32±5.24) respectively at 1, 3, 6 months and the final follow-up after operation. There were no significant difference in PPMS and Harris score at 1, 3, 6 months after operation and the final follow-up(P>0.05). There were no complications such as joint dislocation and prosthesis loosening occure at the final follow-up. CONCLUSION On the premise of strictly mastering the case selection criteria, the bio-lengthend stem hemiarthroplasty in the treatment of unstable osteoporotic intertrochanteric fractures in elderly patients has a satisfied medium term follow-up outcomes. It can restore hip function in the early stage and improve the quality of life of patients.
