Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective: To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for patients with acute leukemia who are positive for the SET-NUP214 fusion gene (SET-NUP214⁺AL). Methods: This was a retrospective case series study. Clinical data of 18 patients with SET-NUP214⁺AL who received allo-HSCT in the First Affiliated Hospital of Soochow University and Soochow Hongci Hematology Hospital from December 2014 to October 2021 were retrospectively analyzed to investigate treatment efficacy and prognosis. The Kaplan-Meier method was used for survival analysis. Results: Of the 18 patients, 12 were male and 6 were female, and the median age was 29 years (range, 13-55 years). There were six cases of mixed phenotype acute leukemia (three cases of myeloid/T, two cases of B/T, one case of myeloid/B/T), nine cases of acute lymphoblastic leukemia (ALL) (one case of B-ALL and eight cases of T-ALL), and three cases of acute myeloid leukemia. All patients received induction chemotherapy after diagnosis, and 17 patients achieved complete remission (CR) after chemotherapy. All patients subsequently received allo-HSCT. Pre-transplantation status: 15 patients were in the first CR, 1 patient was in the second CR, 1 was in partial remission, and 1 patient did not reach CR. All patients were successfully implanted with stem cells. The median time of granulocyte and platelet reconstitution was +12 and +13 days, respectively. With a median follow-up of 23 (4-80) months, 15 patients survived, while 3 patients died. The cause of death was recurrence of SET-NUP214⁺AL after transplantation. After allo-HSCT, 5 patients relapsed. The estimated 3-year overall survival (OS) and relapse-free survival (RFS) rates were 83.3%±15.2% and 55.4%±20.7%, respectively. Among the 15 patients who achieved CR before transplantation, there was no significant difference in OS and RFS between haploidentical HSCT and matched sibling donor HSCT (all P>0.05). Conclusions: Allo-HSCT can improve the prognosis and long-term survival rate of patients with SET-NUP214⁺AL. Disease recurrence is the most important factor affecting long-term survival.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

In this paper, Asarum polysaccharides(AP) were extracted, and its composition was analyzed to study the activity against H1 N1 influenza virus in vitro and its intervention effect on mice with kidney Yang deficiency syndrome. AP was prepared by the strategy of water extraction and alcohol precipitation, the content was determined, and its monosaccharide composition was analyzed. The cell Real-time monitoring system and Reed-Muench model were adopted to evaluate the antiviral activity of AP in vitro. And the mouse model of kidney Yang deficiency syndrome was established in vivo to compare the efficacy of Mahuang Xixin Fuzi Decoction(MXF) and AP. MXF group and AP group were treated with clinical equivalent doses of 1.8 g·kg~(-1)·d~(-1) and 0.077 g·kg~(-1)·d~(-1) respectively, once a day for 6 consecutive days. Real-time PCR was used to detect the relative expression of M gene of H1 N1 influenza virus and cytokines in lung tissue. The content of AP in Asarum was 25.22%, and the protein content was 0.8%. And the monosaccharide composition was identified as L-rhamnose, D-arabinose, D-xylose, D-glucose, D-galactose and D-mannose. TI values of Tamiflu, MXF and AP were 30.00, 8.06 and 10.33, respectively. Three different doses of AP could significantly reduce the concentration of virus in supernatant. Compared with the model mice, lung indexes of MXF group and AP group decreased significantly(P<0.05), and the relative expression of M gene decreased significantly(P<0.05). The relative expressions of IL-10 and IFN-γ were up-regulated to varying degrees, while the relative gene expressions of IL-1β, IL-6 and MCP-1 were down-regulated to different degrees. In addition, AP could significantly enhance the expression of TNF-α(P<0.01). AP had a good anti-influenza virus activity in vitro, and could protect mice with kidney Yang deficiency syndrome by reducing the viral load in lung tissue, decreasing inflammation damage in lung tissue, and regulating the expression of inflammatory cytokines. Compared with the prescription of MXF, AP had a better antiviral activity.

BACKGROUNDRenal function is associated with mortality and functional disabilities in stroke patients, and impaired autonomic function is common in stroke, but little is known regarding its effects on stroke patients with renal dysfunction. This study sought to evaluate the association between autonomic function and stroke in patients with renal dysfunction.

METHODSThis study comprised 232 patients with acute ischemic stroke consecutively enrolled from February 2013 to November 2014 at Guangdong Provincial Hospital of Chinese Medicine in China. All patients recruited underwent laboratory evaluation and 24 h Holter electrocardiography (ECG). Autonomic function was measured based on the heart rate variability (HRV) using 24 h Holter ECG. Renal damage was assessed through the estimated glomerular filtration rate (eGFR), and stroke severity was rated according to the National Institutes of Health Stroke Scale (NIHSS). The Barthel index and modified Rankin score were also determined following admission. All the clinical covariates that could potentially affect autonomic outcome variables were adjusted with linear regression.

RESULTSIn the patients with a mild or moderate decreased eGFR, the values for the standard deviation of the averaged normal-to-normal RR interval (SDANN) index (P = 0.022), very low frequency (VLF) (P = 0.043), low frequency (LF) (P = 0.023), and ratio of low-to-high frequency power (LF/HF) (P = 0.001) were significantly lower than those in the patients with a normal eGFR. A multinomial linear regression indicated that eGFR (t = 2.47, P = 0.014), gender (t = -3.60, P < 0.001), and a history of hypertension (t = -2.65, P = 0.008) were the risk factors of LF/HF; the NIHSS score (SDANN index: t = -3.83, P < 0.001; VLF: t = -3.07, P = 0.002; LF: t = -2.79, P = 0.006) and a history of diabetes (SDANN index: t = -3.58, P < 0.001; VLF: t = -2.54, P = 0.012; LF: t = -2.87, P = 0.004) were independent factors for the SDANN index, VLF, and LF; the Oxfordshire Community Stroke Project (t = -2.38, P = 0.018) was related to the SDANN index.

CONCLUSIONSAutonomic dysfunction is aggravated with the progression of eGFR stage in patients with acute ischemic stroke; the eGFR is an independent factor of LF/HF in the adjusted models. Stroke severity and a history of diabetes are more significantly associated with HRV in patients with acute ischemic stroke at different stages of renal dysfunction.

OBJECTIVETo evaluate the prognosis effect of Chinese herbal medicines (CHMs) for benefiting qi and activating blood circulation adjunctive to conventional treatment in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).

METHODSA total of 702 patients with ACS who underwent PCI were enrolled and randomly assigned to receive conventional treatment plus CHMs for benefiting qi and activating blood circulation (treatment group, 351 cases) or conventional treatment alone (control group, 351 cases) for 6 months. Six months later, all patients received conventional treatment alone. Follow-ups were scheduled at 6th, 12th, 18th, 24th month after enrollment in April 2008, and the final follow-up visit was during September 2011 and November 2011. The primary endpoint was the composite of cardiac death, nonfatal myocardial infarction or revascularization (PCI or coronary artery bypass grafting); and the secondary endpoint was the composite of re-admission for ACS, congestive heart failure, nonfatal stroke or other thrombus events.

RESULTSA total of 621 (88.59%) patients completed 35.4±3.8 months follow-up, while 80 (11.41%) patients withdrew from the trial (41 in the treatment group and 39 in the control group). The incidence of primary endpoint was 5.7% (20 patients) in the treatment group versus 10.86% (38 patients) in the control group [relative risk (RR): 0.53; 95% confidence interval (CI): 0.30, 0.88; P=0.013; absolute risk reduction (ARR):-0.052, 95% CI: -0.06, 0.01]. The incidence of secondary endpoint was 5.98% (21 patients) in the treatment group versus 10.28% (36 patients) in control group (RR: 0.58, 95% CI: 0.33, 0.97, P=0.037; ARR: -0.043, 95% CI: 0.06, 0.01). Most of the primary and secondary endpoints were occurred in 18 months (84.50% in the treatment group versus 78.10% in the control group).

CONCLUSIONCHMs for benefiting qi and activating blood circulation adjunctive to conventional treatment improved clinical outcomes for patients with ACS after PCI in long-term follow-up.

Water-soluble polysaccharides from traditional Chinese medicine have properties of complex structure and high molecular, resulting in hardly complete their structural characterization.However, a "bottom-up" approach could solve this problem.Glehniae Radix extract was extracted with hot water and then precipitated by 40% ethanol to obtain Glehniae Radix polysaccharides (RGP). Subsequently, a partial acid hydrolysis method was carried out and the effects of acid concentration, time and temperature on hydrolysis were investigated. Under the optimum hydrolysis condition (1.5 mol•L⁻¹ trifluoroacetic acid, 4 h, and 80 ℃), RGP were hydrolyzed to characteristic oligosaccharide fragments. Futher, a hydrophilic liquid chromatography- mass spectrometry method was used for the separation and structural characterization of the polysaccharide hydrolysates. According to MS and MS/MS analysis of several standard disaccharides, a method for determining the type of polysaccharide glycosidic linkage by mass spectrometry was established. The results showed that the polysaccharide hydrolysates were linear glucan containing 1, 4-glycosidic bonds. And gluco-oligosaccharides with the degrees of polymerization (DP) of 4-11 were obtained after partial acid hydrolysis.

BACKGROUNDSubthalamic nucleus deep brain stimulation (STN DBS) is effective against advanced Parkinson's disease (PD), allowing dramatic improvement of Parkinsonism, in addition to a significant reduction in medication. Here we aimed to investigate the long-term effect of STN DBS in Chinese PD patients, which has not been thoroughly studied in China.

METHODSTen PD patients were assessed before DBS and followed up 1, 3, and 5 years later using Unified Parkinson's Disease Rating Scale Part III (UPDRS III), Parkinson's Disease Questionnatire-39, Parkinson's Disease Sleep Scale-Chinese Version, Mini-mental State Examination, Montreal Cognitive Assessment, Hamilton Anxiety Scale and Hamilton Depression Scale. Stimulation parameters and drug dosages were recorded at each follow-up. Data were analyzed using the ANOVA for repeated measures.

RESULTSIn the "off" state (off medication), DBS improved UPDRS III scores by 35.87% in 5 years, compared with preoperative baseline (P < 0.001). In the "on" state (on medication), motor scores at 5 years were similar to the results of preoperative levodopa challenge test. The quality of life is improved by 58.18% (P < 0.001) from baseline to 3 years and gradually declined afterward. Sleep, cognition, and emotion were mostly unchanged. Levodopa equivalent daily dose was reduced from 660.4 ± 210.1 mg at baseline to 310.6 ± 158.4 mg at 5 years (by 52.96%, P < 0.001). The average pulse width, frequency and amplitude at 5 years were 75.0 ± 18.21 μs, 138.5 ± 19.34 Hz, and 2.68 ± 0.43 V, respectively.

CONCLUSIONSSTN DBS is an effective intervention for PD, although associated with a slightly diminished efficacy after 5 years. Compared with other studies, patients in our study required lower voltage and medication for satisfactory symptom control.
