OBJECTIVE: To explore clinical efficacy of autologous platelet-rich plasma(PRP) in treating Rockwood type Ⅲ acromioclavicular dislocation. METHODS: From January 2019 to July 2021, 32 patients with Rockwood type Ⅲ acromioclavicular dislocation were treated with minimally invasive adjustable titanium plate internal fixation, and were divided into PRP group and control group according to whether PRP treatment was performed, with 16 patients in each group. In PRP group, there were 10 males and 6 females, aged from 28 to 47 years old with an average of (36.75±7.14) years old;the time from injury to surgery ranged from 1 to 31 h with an average of (26.13±3.98) h;5 patients on the left side and 11 patients on the right side;PRP was injected once during operation and the 4th and 8th weeks after operation respectively. In control group, there were 8 males and 8 females, aged from 30 to 52 years old with an average of (38.50±5.48) years old; the time from injury to surgery ranged from 1 to 29 h with an average of (25.48±3.11) h;7 patients on the left side and 9 patients on the right side; minimally invasive surgical treatment was performed. Visual analogue scale(VAS) was used to evaluate pain and Constant-Murley score for shoulder joint function was used to evaluate the recovery of shoulder joint movement function before operation and 1, 3, 6, and 12 months after operation respectively. RESULTS: All patients were followed up for 12 to 28 months with an average of (18.3±5.2) months. All incisions patients healed well without adverse events such as infection. Postoperative VAS of PRP group at 1, 3, and 6 months were (5.5±1.2), (3.7±1.6), and (2.4±1.2), respectively, while were lower than those of control group (6.6±1.4), (4.9±1.1), and (3.7±1.3), respectively;and had statistical differences between two groups (P<0.05). There was no statistically significant difference in VAS between two groups before operation and 12 months after operation (P>0.05). Postoperative Constant-Murley scores of PRP group at 1, 3, and 6 months were (64.09±11.61), (73.19±12.89), and (82.61±14.81) points, respectively, which were higher than those of control group were (52.32±17.42), (61.65±14.43), and (72.52±11.04) respectively;and the differences were statistically significant (P<0.05). There was no statistically significant difference in Constant-Murley scores at 12 months after operation between two groups (P>0.05). In PRP group, there was no statistically significant difference at 6 months and 12 months after operation (P>0.05), while there were statistically significant differences at the other time points (1 month after operation compared with before operation, 3 months after operation compared with 6 months after operation, and 3 months after operation compared with 1 month after operation) (P<0.05). In control group, there was no statistically significant difference when comparing 1 month and 3 months after operation (P>0.05), while at the other time points (1 month after operation with before operation, 3 months after operation with 6 months after operation, and 6 months after operation with 12 months after operation), the differences were all statistically significant (P<0.05). CONCLUSION Adjustable titanium plate fixation combined with postoperative injection of PRP for the treatment of Rockwood type III acromioclavicular joint dislocation has effect of promoting the recovery of shoulder joint function and reducing pain.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.

Objective To develop a health belief model(HBM)based adolescent alcohol-related cognition scale to measure adolescent alcohol-related cognition and test its reliability and validity.Methods The adolescents'alcohol-related cognitive scale was developed based on HBM model.By using purposive sampling,three general high schools in Qingpu District,Shanghai were selected.One-third of the classes from grades 10 and 11 in each school were randomly selected,and the students from these classes were surveyed as the research subjects.Exploratory factor analysis and confirmatory factor analysis were used to analyze its reliability(internal consistency reliability and combination reliability)and validity(structural validity,convergent validity,discriminative validity and criterion validity).Results A total of 970 questionnaires were collected,of which 948 were valid,with an effective rate of 97.7%.The adolescents'alcohol-related cognitive scale contained 22 items.Five common factors were extracted from exploratory factor analysis,including perceived susceptibility,perceived severity,perceived benefits,perceived obstacles,and self-efficacy.The cumulative variance contribution rate reached 83.89%.The results of confirmatory factor analysis confirmed the overall fit of the model.The average variance extracted value(AVE)of each dimension was greater than 0.5,and the convergent validity of the model was ideal.The AVE square root of each dimension of the scale was greater than its correlation coefficient,indicating good discrimination validity.Cronbach's α coefficient of the total volume table was 0.892,indicating good overall reliability.Conclusion The adolescents'alcohol-related cognitive scale developed in this study has good reliability and validity,which can be used to measure adolescents'alcohol-related perceptions.

Objective:To analyze the expression levels and clinical significance of interferon (IFN)-α/β in the renal cortex and serum of children with lupus nephritis (LN).Methods:A total of 32 children with LN diagnosed in the pediatric nephrology department of the Second Xiangya Hospital of Central South University from December 2017 to September 2020 were selected as the study subjects (LN group). The normal kidney control group consisted of 3 normal kidney transplant volunteers who underwent biopsy of kidney tissue (normal kidney control group), while 14 healthy children who underwent physical examination were collected as the normal control group. According to the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), LN patients were divided into mild activity group ( n=8), moderate activity group ( n=9), and severe activity group ( n=15). According to the International Society of Nephrology/Society of Nephrology (ISN/RPS) 2003 LN classification criteria, pathological classification was performed (3 cases in the mild pathological damage group, 8 cases in the moderate pathological damage group, and 11 cases in the severe pathological damage group); Immunohistochemistry was used to detect the expression and distribution of IFN-α/β in glomeruli and renal interstitium; Enzyme linked immunosorbent assay (ELISA) was used to detect the concentration of IFN-α/β in serum samples and analyze its correlation with the pathological classification and disease activity of LN patients. Results:The serum and renal cortex IFN-α/β levels in the LN group were higher than those in the normal control group and normal kidney control group, respectively (all P<0.05). The average level of serum IFN-α/β in the heavy activity group was higher than that in the light and moderate activity groups (all P<0.05). The serum and renal cortex IFN-α/β levels in the severe pathological damage group were significantly higher than those in the mild and moderate pathological damage groups (all P<0.05). Conclusions:IFN-α/β in the renal cortex is closely related to renal injury in LN; Serum IFN-α/β can assist in evaluating the disease activity level of LN to a certain extent.

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.

With the decline in hepatitis B virus (HBV) incidence and the increase in the life expectancy of infected individuals, the population infected with HBV is experiencing rapid aging, leading to an escalating risk of co-morbid chronic noncommunicable diseases (NCDs). This study summarizes research related to the comorbidity between HBV and NCDs, discussing the aging of the HBV-infected population, the mechanisms, prevalence, and management of this comorbidity. This study provides insights into potential directions for future research on the comorbidity between HBV and NCDs and aims to provide a basis for further research and the development of prevention and treatment strategies for the comorbidity of NCDs among HBV-infected individuals in China.

This paper analyzed the clinical data, diagnosis and treatment of 4 asymptomatic patients with ureteral calculi without hydrops in our hospital from October 2018 to January 2019, and comprehensively discussed the previous literature. The 4 patients in this group had no obvious clinical symptoms, no positive stones were found in the B-ultrasound of the urinary system, and no hydroureter and hydroureter of the affected side was found. Urinary CT scan confirmed ureteral stones. They were all located in the lower ureter, and the stones obstructed the lumen. The stones were round and smooth, and there was no obvious hyperplasia and edema in the surrounding mucosa. The lithotripsy was completed in the first-stage operation, and the DJ catheter was left behind for one month after the operation. Based on the clinical diagnosis and treatment process of the 4 cases of asymptomatic calculi in this group and the analysis of previous studies, these patients were mostly detected by imaging examinations or other systematic imaging examinations during the regular review of urinary calculi. Ureteral stones with obstruction did not necessarily have stone-related symptoms. The onset of renal colic involved an increase in intraluminal pressure, related stimulation of nerve endings, smooth muscle spasms caused by stretching of the ureteral wall, and systemic changes in cytokines and related hormones. Cascade reactions, etc., were associated with the movement of stones down. Ureteral stones without hydrops were mostly located in the lower ureter, which had a certain buffering effect on obstructive pressure. Asymptomatic ureteral calculi could also induce irreversible damage to renal function, and the proportion of damage increased with the diameter of the stone. Patients with a history of urinary calculi, especially those with asymptomatic stones for the first time, should be paid attention to during clinical follow-up. At present, there are few research reports on asymptomatic and non-accumulating ureteral calculi. We analyze the clinical diagnosis and treatment process and characteristics of this group of patients combined with previous literature to provide a reference for the diagnosis and treatment of such patients.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

OBJECTIVE: To investigate the association between the expression level of platelet-activating factor acetylhydrolase 1B3 (PAFAH1B3 ) gene in bone marrow CD138⁺ cells of patients with multiple myeloma (MM) treated with autologous hematopoietic stem cell transplantation (AHSCT) and the prognosis within 2 years. METHODS: 147 MM patients treated with AHSCT in The First and The Second Affiliated Hospital of Nantong University from May 2014 to May 2019 were included in the study. Expression level of PAFAH1B3 mRNA in bone marrow CD138⁺ cells of the patients was detected. Patients with disease progression or death during 2 years of follow-up were included in progression group, and the rest were included in good prognosis group. After comparing the clinical data and PAFAH1B3 mRNA expression levels of the two groups, the patients were divided into high PAFAH1B3 expression group and low PAFAH1B3 expression group based on the median PAFAH1B3 mRNA expression level of the enrolled patients. Progression-free survival rate (PFSR) between the two groups was compared by the Kaplan-Meier method. The related factors of prognosis within 2 years were analyzed by univariate analysis and multivariate COX regression analysis. RESULTS: At the end of follow-up, there were 13 patients lost to follow-up. Finally, 44 patients were included in the progression group and 90 patients were included in the good prognosis group. Age in the progression group was higher than that in the good prognosis group, the proportion of patients with CR+VGPR after transplantation in the progression group was lower than that in the good prognosis group, and there was a statistical difference between two groups in the cases distribution of ISS stage (all P<0.05). PAFAH1B3 mRNA expression level and the proportion of patients with LDH>250U/L in the progression group were higher than those in the good prognosis group, and platelet count in the progression group was lower than that in the good prognosis group (all P<0.05). Compared with the low PAFAH1B3 expression group, the 2-year PFSR of the high PAFAH1B3 expression group was significantly lower (log-rank χ²=8.167, P=0.004). LDH>250U/L (HR=3.389, P=0.010), PAFAH1B3 mRNA expression (HR=50.561, P=0.001) and ISS stage Ⅲ(HR=1.000, P=0.003) were independent risk factors for prognosis in MM patients, and ISS stage Ⅰ (HR=0.133, P=0.001) was independent protective factor. CONCLUSION The expression level of PAFAH1B3 mRNA in bone marrow CD138⁺ cells is related to the prognosis of MM patients treated with AHSCT, and detecting PAFAH1B3 mRNA expression can bring some information for predicting PFSR and prognostic stratification of patients.
