ABSTRACT
ObjectiveTo explore the clinical efficacy of Gandou decoction in treating Wilson's disease （WD） with dampness heat accumulation accompanied by rapid eye movement （REM） sleep behavior disorder （RBD）. MethodFrom April 2019 to August 2023，62 patients with dampness heat accumulation type WD accompanied by RBD who met the inclusion criteria were selected from the Department of Encephalopathy at the First Affiliated Hospital of Anhui University of Chinese Medicine. They were randomly divided into a control group and an observation group with 31 cases each using a computer distributor. The control group received routine copper removal treatment，while the observation group received additional treatment with Gandou decoction on the basis of the control group. Eight days was one course of treatment，totaling three courses. The scores of traditional Chinese medicine syndromes，RBD screening questionnaire （RBDSQ） scores，RBD questionnaire-Hong Kong （RBDQ-HK） scores，polysomnography （PSG） parameters，24-hour urine copper （24 h U-Cu） levels，and non-ceruloplasmin-bound copper （NCC） levels between the two groups before and after treatment were compared，and adverse reactions were observed. ResultSixty trial cases were ultimately completed，with 30 cases in each group. Before treatment，there was no statistically significant difference in various indicators between the two groups， and thus they were comparable. Compared with those before treatment，the traditional Chinese medicine syndrome scores，RBDSQ scores and RBDQ-HK scores of the two groups were significantly reduced，the 24 h U-Cu levels were significantly increased，and the NCC levels were significantly reduced （P<0.05，P<0.01）. Compared with the control group， the observation group showed better improvement in traditional Chinese medicine syndrome scores， RBDSQ scores， RBDQ-HK scores， and NCC levels （P<0.05，P<0.01）. Compared with those before treatment，the total sleep time （TST），sleep efficiency （SE），sleep/REM latency，the proportion of N1/N2/REM stages，arousal index （ARI），and proportion of phasic electromyographic activity （P-EMG-A） were significantly improved in both groups （P<0.05）. Compared with the control group after treatment，the observation group showed more significant improvements in the proportion of TST，SE，REM stages，ARI，and P-EMG-A proportion （P<0.05）. ConclusionGandou decoction can not only improve the traditional Chinese medicine syndrome of WD patients with dampness heat accumulation accompanied by RBD but also alleviate their RBD symptoms.
ABSTRACT
ObjectiveA high-risk group of diabetes in a community in Shanghai was followed up for 2 years. The level of blood glucose control was monitored， the incidence and risk factors of the high-risk group were analyzed， and the incidence and risk factors distribution in the community were studied. The results will provide a basis for the community to formulate strategies for early prevention and treatment of diabetes in Shanghai. MethodsA total of 580 subjects were collected， according to the criteria of high-risk groups of diabetes. Among them， 77 people whose blood glucose had reached the diagnostic criteria for diabetes entered the patient group， and the rest 503 people entered the high-risk group. Corresponding intervention methods such as outpatient follow-up and health education were given， and blood glucose monitoring was repeated at the 12th month and 24th month after enrollment. Blood glucose control， new-onset diabetes and the effect of intervention were analyzed. ResultsThe patients’ venous fasting blood glucose level at the 12th and 24th month was significantly lower than that at the baseline survey， and there was no significant change in body mass index （BMI） and waist circumference. Subjects in patient group were older and had a higher proportion of a history of impaired glycemic regulation， family history of diabetes， hypertension， and hyperlipidemia than those in high-risk group. In the high-risk group of 503 cases， 74 （14.7%） were new-onset diabetics during the follow-up period， A higher proportion of new-onset diabetics were male， BMI， a combined history of impaired glucose regulation and gestational diabetes history of gestational diabetes mellitus （women only） was a contributing factor to the onset of diabetes. ConclusionHigh-risk groups are more susceptible to diabetes； patients in the diabetes group have better control of fasting blood glucose levels during the 2-year follow-up period， and outpatient follow-up combined with comprehensive interventions helps diabetic patients to control blood glucose.
ABSTRACT
ObjectiveTo observe the clinical efficacy of Gandouling decoction combined with cognitive behavioral therapy （CBT） in the treatment of impulse control disorders in patients with Wilson's disease （WD， syndrome of combined phlegm and stasis）. MethodA prospective study was conducted on 90 WD patients with the syndrome of combined phlegm and stasis and impulse control disorders （ICD） treated in the Department of Encephalopathy of the First Affiliated Hospital of Anhui University of Chinese Medicine from August 2018 to February 2023. They were randomized into a control group， a CBT group， and a treatment group， with 30 patients in each group. The control group received routine Western medicine treatment （basic copper removal）. The CBT group received cognitive behavioral therapy in addition to the therapy in the control group， and the treatment group received Gandouling decoction in addition to the therapy in the CBT group. Each course of treatment was 8 days， and the patients were treated for 4 courses. Before and after treatment， the 24-hour urine copper （24 h U-Cu）， non-ceruloplasmin-bound copper （NCC）， traditional Chinese medicine （TCM） syndrome score， unified WD rating scale part Ⅲ （UWDRS Ⅲ） score， Barratt Impulse Scale Version 11 （BIS-11） score， Buss-Perry aggression questionnaire （BPAQ） score， modified overt aggression scale （MOAS） score， and treatment emergent symptom scale （TESS） score of three groups of patients were determined and statistically analyzed. ResultBefore treatment， there was no statistically significant difference in the level of 24 h U-Cu or NCC among the three groups. After treatment， all the three groups showed an increase in 24 h U-Cu （P<0.01） and a decrease in the NCC level （P<0.05， P<0.01）. There was no significant difference in the 24 h U-Cu level among the three groups after treatment. After treatment， the NCC level showed no significant difference between the control group and the CBT group， while the NCC level in the treatment group was lower than that in the control group and CBT group （P<0.05）. Before treatment， there was no statistically significant difference in the TCM syndrome score among the three groups. After treatment， the TCM syndrome scores of all the three groups decreased （P<0.01）. Moreover， the treatment group had lower TCM syndrome score than the control group and CBT group （P<0.05）. Before treatment， the UWDRS Ⅲ， BIS-11， BPAQ， and MOAS scores had no statistically significant differences among the three groups. After treatment， the UWDRS Ⅲ， BIS-11， BPAQ， and MOAS in all the three groups declined （P<0.05）. Moreover， the CBT group and treatment group had lower UWDRS Ⅲ， BIS-11， BPAQ， and MOAS scores than the control group （P<0.05）， and the treatment group had lower BIS-11 and BPAQ scores than the CBT group （P<0.05）. ConclusionThe combination of Gandouling decoction and CBT can ameliorate impulse control disorders in the WD patients with combined phlegm and stasis.

ABSTRACT
Objective:To analyze risk factors for unfavorable outcomes after recanalization of large vessel occlusion (LVO) in patients with acute ischemic stroke (AIS).Methods:Patients with AIS-LVO who underwent recanalization treatment (including intravenous thrombolysis and endovascular intervention) at the Stroke Unit of Beijing Hospital from August 2018 to January 2022 were consecutively enrolled. According to the modified Rankin Scale (mRS) at 90-day follow-up after recanalization treatment, participants were classified as unfavorable outcomes (mRS>2) and favorable outcomes (mRS≤2). Baseline clinical data of enrolled patients was collected, and step-wise multivariate logistic regression analysis was used to identify independent risk factors for unfavorable outcomes after recanalization in AIS-LVO patients.Results:A total of 212 AIS-LVO patients were enrolled, including 86 females (41.35%), with an average age of 72.9 years. There were 75 patients in the favorable outcome group and 137 patients in the unfavorable outcome group. Compared with the favorable outcome group, the unfavorable outcome group had a higher average age, a higher proportion of females and patients with atrial fibrillation, higher baseline NIHSS, higher systolic blood pressure, and higher blood creatinine and D-dimer levels (all P<0.05). After adjusting for age and atrial fibrillation as confounding factors, multivariate logistic regression analysis showed that female ( OR=2.859, 95% CI: 1.202-6.799, P=0.018), higher baseline NIHSS ( OR=14.417, 95% CI: 6.269-33.158, P<0.001), higher pre-treatment systolic blood pressure ( OR=1.034, 95% CI: 1.015-1.054, P=0.001), higher emergency blood creatinine level ( OR=1.378, 95% CI: 1.105-1.719, P=0.005), and higher D-dimer level ( OR=3.594, 95% CI: 1.290-10.014, P=0.014) were independent risk factors for unfavorable outcomes after recanalization treatment in patients with AIS-LVO. Conclusion:Female, higher NIHSS, higher systolic blood pressure, higher blood creatinine level and D-dimer level are independent risk factors for unfavorable functional outcomes at 90 days after recanalization treatment of large vessel occlusion in patients with acute ischemic stroke.
ABSTRACT
Objective:To investigate the long-term follow-up results and the risk factors of bleeding among very elderly patients with non-valvular atrial fibrillation (NVAF).Methods:A total of 177 patients with NVAF admitted in Beijing Hospital from January 2016 to July 2016 were enrolled in the study, including 107 very elderly patients (aged≥80 years) and 70 elderly patients (aged 65-80 years). The demographic information, comorbid diseases, lifestyles, antithrombotic therapy, thromboembolism risks, bleeding risks, and medical history were documented. Patients were followed up for 5 years and the events of death, thromboembolism, bleeding and major bleeding were recorded.Results:There was no significant difference in the incidence of thromboembolic events between the two groups (15.9%(17/107) vs. 14.3%(10/70), P>0.05). The proportions of bleeding events and severe bleeding events in the very elderly group were higher than those in the elderly group (45.8%(49/107) vs.10.0%(7/70), 14.0%(15/107) vs. 1.4%(1/70), both P<0.05). According to the bleeding events during follow-up, very elderly patients were divided into bleeding group ( n=49) and non-bleeding group ( n=58). Compared with the non-bleeding group, patients in the bleeding group had an older age, a higher proportion of chronic cardiac insufficiency, chronic kidney disease, malignant tumor, bleeding history and higher bleeding risk score (HAS-BLED score) (all P<0.05). Multivariate logistic regression model analysis showed that age, HAS-BLED score, history of bleeding, and complicated malignant tumor were independent risk factors for bleeding events in very elderly patients with NVAF (all P<0.05). Conclusions:Very elderly patients with NVAF have a similar risk of thromboembolism compared with the younger elderly, but have significantly higher risk of the bleeding and major bleeding. Age, HAS-BLED score, bleeding history, and malignant tumor are independent risk factors for bleeding events in very elderly NVAF patients.
ABSTRACT
Objective:To summarize the efficacy and safety of transurethral partial cystectomy combined with intravesical suturation in the treatment of bladder cancer.Methods:The clinical data of 28 patients with bladder cancer who were admitted in Zhengzhou People's Hospital from July 2020 to October 2021 were analyzed retrospectively. There were 22 males and 6 females, with the average age of (68.8±8.9) years old. Twenty cases were with single bladder tumor, and 8 cases were with multiple bladder tumors. The diameter of single bladder tumor measured by CT was less than 4 cm, with a median tumor diameter of 2.3(0.9, 2.8)cm. All 28 patients underwent transurethral partial cystectomy combined with intravesical suturation for the first time. Intraoperative intravesical instillation was conducted with 1 g gemcitabine. Bladder hot reperfusion treatment was performed with gemcitabine 2 g at 45℃ immediately after operation. The patients underwent reexamination with cystoscopy every 3 months after operation.Results:All the 28 patients successfully completed the operation. The average operation time was (128.3±16.3)min. No obturator nerve reflection was induced during operation. Muscularis tissue was found in all tumor pathological specimens after operation, among which 4 cases showed muscularis infiltration. Pathology of tumor basal and peripheral tissues showed tumor cell infiltration in 3 cases (1 case full-thickness infiltration, namely the incision margin was positive). The median continuous irrigation time of bladder after operation was 24.0(20.9, 25.0)h. The median time of indwelling catheter after operation was 6.5(6.0, 7.0)days, and one case developed severe bladder spasm. All patients were followed up, with a median follow-up of 7.5(4.0, 10.8) months.Postoperative recurrence occurred in 3 cases, all of which were ectopic recurrence in bladder.The 1-year recurrence rate was 10.7% (3/28).Conclusions:In the first surgical treatment of bladder cancer, transurethral partial cystectomy combined with intravesical suturation can provide accurate pathological staging, and low positive surgical margin rate. Immediate suturation of bladder wound during operation and immediate bladder perfusion chemotherapy can provide short bladder irrigation time, with few adverse reactions and low incidence of complications.
ABSTRACT
Objective:To study the factors influencing repeatedly hospitalization in patients with acute pancreatitis (AP), and to analyse the predictive value of triglyceride for repeated hospitalization.Methods:The clinical data of 1 958 patients with AP treated at the First Affiliated Hospital of Anhui University of Science and Technology from January 2012 to April 2022 were analyzed. Of 1 733 AP patients who were enrolled, there were 1 000 males and 733 females, with mean ± s. d age being (49.4±16.4) years. Patients were grouped based on their ID numbers to determine their number(s) of hospitalization. Those who were admitted only once were included in the initial hospitalization group ( n=1 030), and those who were admitted twice or more were included in the repeated hospitalization group ( n=703). The factors influencing repeated hospitalization were analyzed by univariate analysis and multivariate logistic regression analysis. The predictive value of triglyceride for repeated hospitalization was evaluated by receiver operating characteristic (ROC) curve. Results:Multivariate logistic regression analysis showed that hypertriglyceridemia ( OR=1.445, 95% CI: 1.144-1.825, P=0.002) and biliary causes ( OR=3.184, 95% CI: 1.978-5.125, P<0.001) were independent risk factors for repeated hospitalization. When triglyceride <10.9 mmol/L, the prediction of AP patients without repeated hospitalization was 90.6%. The area under the ROC curve was 0.589, and the Yoden index was 0.170. Conclusion:Hypertriglyceridemia was risk factor for repeat hospitalization in AP patients and the efficacy of triglyceride in predicting repeat hospitalization in AP patients was good.

ABSTRACT
Objective:To observe the application of near-infrared autofluorescence imaging (NIRAF) technology combined with carbon nanoparticle (CNP) negative imaging in identification of parathyroid gland (PG) during thyroid carcinoma surgery.Methods:80 patients with thyroid cancer who underwent total thyroidectomy + central lymph node dissection performed by the same experienced physician team at the 960th Hospital of the PLA from Jan. to Mar. 2022 were prospectively included. Before operation, they were divided into two groups using random number table method before surgery: control group (40 cases) using CNP negative imaging, and experimental group (40 cases) using CNP negative imaging combined with NIRAF technique for intraoperative identification of PG. The gold standard for the identification of parathyroid glands was to compare the amount of intraoperative discovery retention misresection and transplantation of PG and the number of postoperative parathyroid hormone (PTH) and the number of complications in the two groups by immune colloidal gold technique. SPSS 25.0 software was used for statistical analysis.Results:All patients in the two groups were successfully operated and followed up. 137 149 PG were found and confirmed in the control group and the observation group, 108 132 PG were retained in situ and 29 17 PG were transplanted, the differences were statistically significant (all P <0.05) ; The number of A1 PG was 103 and 109, respectively. Among them, 84 102 were retained in situ and 19 7 were transplanted, the difference was statistically significant ( P <0.05) . There was no significant difference in the amount of A2 type PG and B type PG between the two groups ( P >0.05) . No A3 type PG was found in the two groups, and a total of 3 A3 types of PG were confirmed in postoperative pathological reports. There were no significant differences in misresection in the control group and the observation group, 5 and 2 PG were mistakenly cut, respectively (all P >0.05) . The PTH 1 day after surgery was 17.7 (5.6,30.4) pg/mL in the control group and 21.7 (12.8,38.3) pg/mL in the observation group, the difference was statistically significant ( P<0.05) . There were no significant differences in the levels of serum calcium and serum phosphorus 1 day after operation and PTH 1 month after surgery between the two groups (all P > 0.05) . Conclusion:Compared with CNP alone, combined with NIRAF technique can quickly and effectively identify PG, and PG can be better protected in situ and postoperative hypoparathyroidism can be reduced.

ABSTRACT
The passing of ethical review is a necessary conditions and prerequisite for the development of life science and medical research involving humans. At present, some medical and health institutions have no or insufficient ethical review capabilities. The lack of ethical review ability has become a bottleneck restricting the development of life science and medical research involving humans. According to documents such as Opinions on Deepening the Reform of the Review and Approval System and Encouraging the Innovation of Pharmaceutical and Medical Devices, Opinions on Strengthening the Ethical Governance of Science and Technology, institutions can entrust competent institutional ethics review committees or regional ethics review committees in writing to conduct ethical review. Entrustment ethical review provides a viable solution for institutions that need to carry out life science and medical research involving humans but do not have an ethics (review) committee or the ethics (review) committee is not competent to review. To conduct the entrustment ethical review, the entrustment between the principal and the trustee is required. According to The Measures for Ethical Review of Life Sciences and Medical Research Involving Humans, if medical and health institutions and their ethical review committees do not accept the formal entrustment to provide the ethical review opinions for other institutions, the local health authorities at or above the county level will impose administrative penalties and sanctions on the relevant institutions and personnel in accordance with the law. Signing the entrustment ethical review contract, implementing legal compliance entrusted ethical review to protect the rights and interests of the trustee and the principal, and protect the research participants.
ABSTRACT
The seventh article of Measures for the Ethical Review of Biomedical Research Involving Humans (2016) stipulated that medical and health institutions without an ethics committee shall not carry out biomedical research involving Humans. The Opinions on Strengthening the Governance of Ethics in Science and Technology, issued in March 2022, clearly stated that the institutions that do not meet the conditions for establishing a scientific and technological ethics (review) committee should entrust other institutions to conduct the review. The fourteenth article of Measures for Ethical Review of Life Science and Medical Research Involving Humans (2023) proposes that if an institution, which carries out life science and medical research involving humans, has not established an ethics committee or its ethics committee is not competent for ethics review, it can entrust a competent ethics committee or regional ethics committee in writing to carry out ethical review. Most medical institutions at or above the second level in China have set up ethics committees. While most universities and colleges, scientific research institutions, enterprises and grass-roots medical and health institutions have not set up ethics committees, which lack a working system to protect the safety and interests of the participants, and is difficult to conduct life sciences and medical research involving humans. At present, there is a need for some research institutions that do not have the conditions to establish ethics committees to entrust their projects of life science and medical research involving humans to other institutions for ethical review. The entrusted review is still in the exploratory stage, and there is no relevant specification. The hasty implementation of entrusted review may not achieve the goal of effectively protecting the safety and interests of the participants, and even cause legal disputes. Based on the thematic discussion, with reference to the relevant laws and regulations, departmental rules, ethical standards, and the experience of the ethics committees of some domestic institutions in implementing the entrusted review, the guideline was formulated for the reference of the current entrusted review to ensure the safety and interests of the participants.
ABSTRACT
Objective To analyze and describe the morphological characteristics of the proximal origin of the biceps brachii, and measure the anatomical data of its tendons, so as to provide references for related clinical applications of the biceps brachii. Methods Six adult shoulder specimens (4 on the left and 2 on the right) were dissected to observe the origin, morphology, and course of the biceps brachii tendon and its adjacent relationship with the coracobrachialis muscle, musculocutaneous nerve and other structures. And then the length, width, and thickness of the biceps tendon were measured. Results The origin of the short head of biceps consisted of muscle fibers attaching directly to the tip of the coracoid process, with a thin, tendinous aponeurosis covering its anterior surface, rather than a true tendon as previously described. The mean of length,widths and thickness of the short head of biceps were (107.7±9.6) mm,(20.0±1.5)mm and (5.8±2.0)mm. Conclusion The short head of the biceps brachii is directly from the coracoid process with muscle fibers.
ABSTRACT
Tenapanor is a novel phosphorus-lowering drug, which mainly inhibits sodium/hydrogen exchange protein 3 (NHE3), and also reduces intestinal phosphorus absorption by down-regulating the expression of sodium phosphate co-transporter protein (NAPI). Tenapanor is mainly used for the treatment of hyperphosphatemia in patients with end-stage renal disease-hemodialysis (ESRD-HD). Diarrhea is the most common adverse reaction to this product. This article reviews Tenapanor by performing a literature search on its pharmacological effects, pharmacokinetic properties, clinical evaluation, safety, drug interactions and dosage.
ABSTRACT
Aim To investigate the mechanism and search for potential biomarkers of ovalbumin ( OVA ) -induced asthma in mice base on lipidomics. Methods A BALB/c mouse model of asthma was prepared by OVA. TNF-α, IL-4, IL-10, IFN-γ levels in BALF and IgE level in serum were measured by ELISA. The inflammatory changes in mouse lung tissue were observed using HE staining. Lipid mediators ( LMs) in lung tissue and serum were quantified with UPLC-MS/ MS strategy. Results IgE level in serum and TNF-α, IFN-γ levels in BALF were higher (P <0.05) of asthmatic mice.Typical inflammatory manifestations were seen in lung tissue of asthmatic mice. A total of 57 lipid mediators were quantified with UPLC-MRM. LMs metabolic profiles differed significantly in serum and lung tissue between asthmatic and normal mice, 17 significantly different LMs were found in lung tissue and 6 LMs were found in serum, and the differential metabolites were produced through the cyclooxygenase (COX), lipoxygenase (LOX) and cytochrome P450 oxidase (P450) metabolic pathways. Conclusions OVA-induced allergic asthma can cause disorder of lip-id mediators, LMs and cytokines are involved in the occurrence and development of asthma. The differential LMs have potential research value as biomarkers for the development of allergic asthma.

ABSTRACT
Long non-coding RNAs (lncRNAs) play an important role in cancer metastasis. Exploring metastasis-associated lncRNAs and developing effective strategy for targeted regulation of lncRNA function in vivo are of utmost importance for the treatment of metastatic cancer, which however remains a big challenge. Herein, we identified a new functional lncRNA (denoted lncBCMA), which could stabilize the expression of eukaryotic translation elongation factor 1A1 (eEF1A1) via antagonizing its ubiquitination to promote triple-negative breast cancer (TNBC) growth and metastasis. Based on this regulatory mechanism, an endosomal pH-responsive nanoparticle (NP) platform was engineered for systemic lncBCMA siRNA (siBCMA) delivery. This NPs-mediated siBCMA delivery could effectively silence lncBCMA expression and promote eEF1A1 ubiquitination, thereby leading to a significant inhibition of TNBC tumor growth and metastasis. These findings show that lncBCMA could be used as a potential biomarker to predict the prognosis of TNBC patients and NPs-mediated lncBCMA silencing could be an effective strategy for metastatic TNBC treatment.
ABSTRACT
Objective: To investigate the value of plasma cells for diagnosing lymph node diseases. Methods: Common lymphadenopathy (except plasma cell neoplasms) diagnosed from September 2012 to August 2022 were selected from the pathological records of Changhai Hospital, Shanghai, China. Morphological and immunohistochemical features were analyzed to examine the infiltration pattern, clonality, and IgG and IgG4 expression of plasma cells in these lymphadenopathies, and to summarize the differential diagnoses of plasma cell infiltration in common lymphadenopathies. Results: A total of 236 cases of lymphadenopathies with various degrees of plasma cell infiltration were included in the study. There were 58 cases of Castleman's disease, 55 cases of IgG4-related lymphadenopathy, 14 cases of syphilitic lymphadenitis, 2 cases of rheumatoid lymphadenitis, 18 cases of Rosai-Dorfman disease, 23 cases of Kimura's disease, 13 cases of dermal lymphadenitis and 53 cases of angioimmunoblastic T-cell lymphoma (AITL). The main features of these lymphadenopathies were lymph node enlargement with various degrees of plasm cell infiltration. A panel of immunohistochemical antibodies were used to examine the distribution of plasma cells and the expression of IgG and IgG4. The presence of lymph node architecture could help determine benign and malignant lesions. The preliminary classification of these lymphadenopathies was based on the infiltration features of plasma cells. The evaluation of IgG and IgG4 as a routine means could exclude the lymph nodes involvement of IgG4-related dieases (IgG4-RD), and whether it was accompanied by autoimmune diseases or multiple-organ diseases, which were of critical evidence for the differential diagnosis. For common lesions of lymphadenopathies, such as Castleman's disease, Kimura's disease, Rosai-Dorfman's disease and dermal lymphadenitis, the expression ratio of IgG4/IgG (>40%) as detected using immunhistochemistry and serum IgG4 levels should be considered as a standard for the possibility of IgG4-RD. The differential diagnosis of multicentric Castleman's diseases and IgG4-RD should be also considered. Conclusions: Infiltration of plasma cells and IgG4-positive plasma cells may be detected in some types of lymphadenopathies and lymphomas in clinicopathological daily practice, but not all of them are related to IgG4-RD. It should be emphasized that the characteristics of plasma cell infiltration and the ratio of IgG4/IgG (>40%) should be considered for further differential diagnosis and avoiding misclassification of lymphadenopathies.
