OBJECTIVE To investigate the improvement mechanism of Huatan tongmai decoction on rats with polycystic ovary syndrome （PCOS） by regulating autophagy through phosphatidylinositol-3-kinase（PI3K）/protein kinase B（AKT）/mammalian target of rapamycin （mTOR） pathway. METHODS A total of 40 rats were randomly divided into blank group （purified water）， model group （purified water）， traditional Chinese medicine group [Huatan tongmai decoction， 24 g/（kg·d）] and chemical drug group [metformin， 0.16 g/（kg·d）]， with 10 rats in each group. Except for blank group， other groups were given a combination of high-fat diet and intragastric administration of 1 mg/kg letrozole suspension to establish PCOS rat model. After modeling， they were given relevant medicine or water intragastrically， once a day， for 42 consecutive days. After the last administration， the pathological and ultrastructural changes of ovarian tissue were observed. The levels of follicle stimulating hormone （FSH）， testosterone （T）， estradiol （E2） ，luteinizing hormone （LH） in serum were detected，and the LH/FSH ratio was calculated. mRNA expressions of Beclin-1， p62 and microtubule-associated protein 1 light chain 3 （LC3） in ovarian tissue were detected. The expressions of related proteins of PI3K/AKT/mTOR pathway and autophagy in rat ovarian tissues were also detected. RESULTS Compared with blank group， the pathological damage and ultrastructural changes of the ovarian tissue in the model group rats were obvious， and a large number of autophagosomes could be seen in cells. The levels of T and LH and the LH/FSH ratio in serum， as well as mRNA and protein expressions of Beclin-1 and LC3， were increased significantly （P＜0.05）， while the levels of E2 and FSH in serum， as well as mRNA and protein expressions of p62 and the phosphorylation levels of PI3K， AKT and mTOR proteins in ovarian tissue， were significantly decreased （P＜0.05）. Compared with model group， the pathological damage of ovarian tissue in the administration groups was significantly reduced， the number of autophagosomes was smaller， and the expression levels of the above indicators were significantly reversed （P＜0.05）. CONCLUSIONS Huatan tongmai decoction can inhibit autophagy in ovarian granular cells by activating the PI3K/AKT/mTOR pathway， regulate the secretion of sex hormones， alleviate pathological damage in ovarian tissues， and promote normal follicular development， thereby exerting an ameliorative effect on PCOS rats.

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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Aim To explore the effects of ethanol extraction of Dysosma versipellis on the proliferation and apoptosis of renal clear cell carcinoma OS-RC-2 cells and the underlying mechanism. Methods After treated with Dysosma versipellis, the proliferation of OS-RC-2 cells was detected by the CCK-8 assay and clone formation assay. The migration rate of cells was detected by thewound healing assay and Transwell assay. The level of ROS was detected by the reactive oxygen detection kit. The common targets between Dysosma versipellis and ROS were obtained by the network pharmacology. The above common targets were analyzed by KEGG. The apoptosis rate and cell cycle were detected by the flow cytometry, and the key proteins of MAPK signaling pathway and the levels of apoptosis related proteins were measured by Western blot. Results The results showed that Dysosma versipellis significantly inhibited the cell viability and migration ability of 0S-RC-2 cells, and up-regulated the level of ROS. Network pharmacology analysis showed a total of 165 common targets between Dysosma versipellis and ROS. KEGG analysis of the common targets revealed that there were significant changes in the MAPK signaling pathway. The results of Western blot showed that after treated with Dysosma versipellis, the protein level of JNK and the ratio of p-ERK/ERK were down-regulated. Besides, the protein level of caspase-9 and Bcl-2 declined, while the levels of cleaved caspase-9 and Bax were promoted. The flow cytometry results showed that Dysosma versipellis could significantly promote the apoptosis rate,down-regulate the cells in Gl-phase,while up-regulate the cells in G2/M-phase. The results of the rescue experiment showed that co-administration of NAC and Dysosma versipellis could significantly reverse the cell viability and apoptosis rate, the level of apop-totic related proteins, as well as the protein levels of MAPK pathway,when compared to treated with Dysosma versipellis alone in OS-RC-2. Conclusion In summary, Dysosma versipellis may inhibit the MAPK signaling pathway via the changes in ROS,further promoting apoptosis rate and decline cell proliferation in OS-RC-2 cell line.

OB JECTIVE To explore the construction of system of pharmacoeconomic evaluation fo r Chinese patent medicine in preventing and treating major chronic diseases. METHODS The problems in pharmacoeconomic evaluation of Chinese patent medicine for preventing and treating major chronic diseases were analyzed. Based on the problem ，the pharmacoeconomic theory ， tools and methods that can be used to systematically evaluate the prevention and treatment of major chronic diseases by Chinese patent medicine were explored to build the relevant pharmacoeconomic evaluation system. RESULTS & CONCLUSIONS Traditional Chinese medicine shows the advantages in the prevention and treatment of major chronic diseases. This unique advantage needed to be explored ，reflected and proved in the pharmacoeconomic evaluation. The pharmacoeconomic evaluation of Chinese patent medicine had made some progress in recent years. However ，there were still deficiencies of theory and methodology in the pharmacoeconomic evaluation for the advantages of Chinese patent medicine in preventing and treating major chronic diseases. It was difficult to truly and comprehensively reflect the value of Chinese patent medicine by simply applying the economic evaluation indicators and technologies of chemical medicine. It is necessary to focus on the unique pharmacoeconomic attributes of Chinese patent medicine ，excavate the economic value indicators of Chinese patent medicine for “preventive treatment of disease ” and playing the self-regulation role of human body ，comprehensively consider the pharmacoeconomic particularity of Chinese patent medicine in respects of research design ，research angle ，target population ，intervention measures and control selection ，research time limit and evaluation method ，etc. Through the use of system modeling ，real-world research and the establishment of Chinese medicinal quality of life scale that reflects the characteristics of TCM ，the economic value of Chinese patent medicine in the prevention and treatmen t of major chronic diseases is reflected comprehensively，so as to reflect the advantage of Chinese patent medicine in preventing and treating major chronic diseases.

Objective:To assess the correlation between frailty and cardiac autonomic nervous system function in elderly patients.Methods:Elderly hospitalized patients aged 65 years and over were enrolled and assessed for frailty by using the clinical frailty scale.Cardiac autonomic modulation was evaluated by heart rate variability analysis through 24 h electrocardiogram recording.Results:A total of 180 elderly patients were enrolled in this study, including 66 patients with frailty and 114 patients without frailty.The mean age of the frailty group was higher than that of the non-frailty group(79.8±6.0 vs.75.0±6.3, t=5.030, P<0.001). The proportions of patients with hypertension, stroke/transient cerebral ischemia attack(TIA), heart failure and osteoarthritis were higher in the frailty group than in the non-frailty group(all P<0.05). Compared with the non-frailty group, the standard deviation of normal-to-normal intervals(SDNN)[103.0(76.0, 121.2) vs.107.5(92.0, 136.0), Z=-2.108, P=0.035], the standard deviation of the averages of NN intervals in all 5-min segments(SDANN)[86.0(67.7, 106.5) vs.97.5(78.0, 126.0), Z=-2.694, P=0.007], normalized low frequency(LFnorm)(53.1±13.0 vs.59.3±13.9, t=-3.024, P=0.003)and low frequency/high frequency(LF/HF)ratio[1.2(1.0, 1.4) vs.1.4(1.1, 1.7), Z=-3.041, P=0.002]were decreased and normalized high frequency(HFnorm)(36.8±9.2 vs.32.2±10.7, t=3.033, P=0.003)was increased in the frailty group.HFnorm in the frailty group was significantly higher than that in the non-frailty group.The incidents of SDANN<92 ms, LFnorm<50 nU, HFnorm>32 nU and LF/HF ratio<1.5 were higher in the frailty group than in the non-frailty group(59.1% or 39/66 vs.41.2% or 47/114, 42.4% or 28/66 vs.22.8% or 26/114, 72.7% or 48/66 vs.49.1% or 56/114, 84.8% or 56/66 vs.65.8% or 75/114, χ2=5.346, 7.660, 9.547, 7.664, P=0.021, 0.006, 0.002, 0.006). Logistic multivariate regression analysis showed that LFnorm, HFnorm and LF/HF ratio were correlated with frailty( OR=0.971, 1.039 and 0.333, all P<0.05), and HFnorm>32 nU and LF/HF ratio<1.5 were risk factors for frailty( OR=2.401 and 2.773, both P<0.05). Conclusions:Cardiac autonomic nerve system function is impaired in elderly frail patients, with the imbalance between the sympathetic and vagus nerves.Therefore particular attention should be paid to heart rate variability in elderly patients with frailty.

Objective: To observe the therapeutic effect of mild moxibustion on irritable bowel syndrome (IBS) visceral hyperalgesiamodel rats and its regulatory effect on P2X3 receptors in the spinal cord, anterior cingutate cortex (ACC) and thalamic ventral posterolateral nucleus (VPL). Methods: Thirty 8-day-old newborn rats were randomly divided into a normal group (n=6) and a modeling group (n=24) according to the completely random number table method. Rats in the normal group were bred routinely, and those in the modeling group were subjected to preparing IBS chronic visceral hyperalgesia model using colorectal distention (CRD) in stimulation method. Rats successfully modelled were re-divided into a model group, a mild moxibustion group, a P2X3 receptor antagonist group, and a normal saline group according to the completely random number table method with 6 rats in each group. Rats in each group received corresponding interventions from the 37-day old, once a day for 7 consecutive days. Immunohistochemistry and Western blot assays were used to detect P2X3 protein expressions in the spinal cord, ACC and VPL of rats. Results: Under different intensities of CRD stimulation, the abdominal withdrawal reflex (AWR) scores of the model group were significantly increased versus the normal group (all P<0.05); the AWR scores of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). The P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the model group were significantly increased versus the normal group (all P<0.01); the P2X3 protein expressions in rat spinal cord, ACC and VPL tissues of the mild moxibustion group and the P2X3 receptor antagonist group were significantly reduced versus the model group (all P<0.01). Conclusion: Mild moxibustion can inhibit the P2X3 receptor expressions in the spinal cord, ACC, and VPL tissues of IBS visceral hyperalgesia model rats, which may be the mechanism of mild moxibustion in relieving the central sensitization of rats with IBS visceral hyperalgesia.

This study investigated the correlation between periprostatic fat thickness (PPFT) measured on magnetic resonance imaging and lower urinary tract symptoms, erectile function, and benign prostatic hyperplasia (BPH) progression. A total of 286 treatment-naive men diagnosed with BPH in our department between March 2017 and February 2019 were included. Patients were divided into two groups according to the median value of PPFT: high (PPFT >4.35 mm) PPFT group and low (PPFT <4.35 mm) PPFT group. After the initial evaluation, all patients received a combination drug treatment of tamsulosin and finasteride for 12 months. Of the 286 enrolled patients, 244 completed the drug treatment course. Patients with high PPFT had larger prostate volume (PV; P = 0.013), higher International Prostate Symptom Score (IPSS; P = 0.008), and lower five-item version of the International Index of Erectile Function (IIEF-5) score (P = 0.002) than those with low PPFT. Both high and low PPFT groups showed significant improvements in PV, maximum flow rate, IPSS, and quality of life score and a decrease of IIEF-5 score after the combination drug treatment. The decrease of IIEF-5 score was more obvious in the high PPFT group than that in the low PPFT group. In addition, more patients in the high PPFT group underwent prostate surgery than those in the low PPFT group. Moreover, Pearson's correlation coefficient analysis indicated that PPFT was positively correlated with age, PV, and IPSS and negatively correlated with IIEF-5 score; however, body mass index was only negatively correlated with IIEF-5 score.

OBJECTIVE: To evaluate the effects of a 48-week course of adefovir dipivoxil (ADV) plus Chinese medicine (CM) therapy, namely Tiaogan Jianpi Hexue () and Tiaogan Jiedu Huashi () fomulae, in hepatitis B e antigen (HBeAg)-positive Chinese patients. METHODS: A total of 605 HBeAg-positive Chinese CHB patients were screened and 590 eligible participants were randomly assigned to 2 groups in 1:1 ratio including experimental group (EG, received ADV plus CM) and control group (CG, received ADV plus CM-placebo) for 48 weeks. The major study outcomes were the rates of HBeAg and HBV-DNA loss on week 12, 24, 36, 48, respectively. Secondary endpoints including liver functions (enzymes and bilirubin readings) were evaluated every 4 weeks at the beginning of week 24, 36, and 48. Routine blood, urine, and stool analyses in addition to electrocardiogram and abdominal B scan were monitored as safety evaluations. Adverse events (AEs) were documented. RESULTS: The combination therapy demonstrated superior HBeAg loss at 48 weeks, without additional AEs. The full analysis population was 560 and 280 in each group. In the EG, population achieved HBeAg loss on week 12, 24, 36, and 48 were 25 (8.90%), 34 (12.14%), 52 (18.57%), and 83 (29.64%), respectively; the equivalent numbers in the CG were 20 (7.14%), 41 (14.64%), 54 (19.29%), and 50 (17.86%), respectively. There was a statistically significant difference between these group values on week 48 (P<0.01). No additional AEs were found in EG. Subgroup analysis suggested different outcomes among treatment patterns. CONCLUSION Combination of CM and ADV therapy demonstrated superior HBeAg clearance compared with ADV monotherapy. The finding indicates that this combination therapy may provide an improved therapeutic effect and safety profile (ChiCTR-TRC-11001263).

BACKGROUND: Intensive therapy with disease modifying anti-rheumatic drugs (DMARDs) has been reported to improve the outcomes of rheumatoid arthritis (RA). However, real-world study on the effect of intensive therapy on RA sustained remission is still lacking. This study aimed to investigate the outcome of sustained intensive DMARD therapy (SUIT) for RA in a real-world 5-year consecutive cohort. METHODS: Based on a consecutive cohort of 610 out-patients with RA, remission of RA was assessed in 541 patients from 2012 to 2017, by dividing into SUIT, non-SUIT, and intermittent SUIT (Int-SUIT) groups. Changes in the disease activity scores were evaluated by 28-joint disease activity score based on erythrocyte sedimentation rate (DAS28-ESR), 28-joint disease activity score based on C-reactive protein (DAS28-CRP), and clinical deep remission criteria (CliDR). Cumulative remission rates between different groups were compared using Kaplan-Meier curves and predictive factors of sustained remission were identified by univariate and multivariate logistic regression analysis. RESULTS: The remission rates of the SUIT group decreased from 12.0% (65/541) to 5.6% (20/359) based on DAS28-ESR, from 14.0% (76/541) to 7.2% (26/359) based on DAS28-CRP, and from 8.5% (46/541) to 3.1% (11/359) based on CliDR, respectively, with a gradually decreasing trend during the 5 years. The SUIT regimen led to a significantly higher cumulative remission rate than non-SUIT regimen based on DAS28-ESR (39.7% vs. 19.5%, P = 0.001), DAS28-CRP (42.0% vs. 19.6%, P = 0.001), and CliDR (24.5% vs. 8.7%, P = 0.001). The cumulative remission rates of patients treated with SUIT regimen were significantly higher than those treated with Int-SUIT regimen based on DAS28-ESR (39.7% vs. 25.7%, P = 0.043) and CliDR (24.5% vs. 14.2%, P = 0.047), but there was no significant difference between the two groups based on DAS28-CRP (42.0% vs. 27.4%, P = 0.066). Multivariate logistic regression analysis showed that the use of SUIT regimen was an independent favorable predictor according to different remission definitions (for DAS28-ESR: odds ratio [OR], 2.215, 95% confidence interval [CI]: 1.271-3.861, P = 0.005; for DAS28-CRP: OR, 1.520, 95% CI: 1.345-1.783, P = 0.002; for CliDR: OR, 1.525, 95% CI: 1.314-1.875, P = 0.013). CONCLUSION Sustained intensive treatment of RA is an optimal strategy in daily practice and will lead to an increased remission rate.
