Background Pneumoconiosis is a prevalent and severely harmful occupational disease in China. Objective To estimate disease burden and trends of different types of pneumoconiosis among Chinese males from 1992 to 2021, and to provide insights for pneumoconiosis prevention and control as well as the development of public health policies in China. Methods Based on the latest data from the Global Burden of Disease (GBD) study (2021), this study evaluated the disease burden of pneumoconiosis among Chinese males using indicators such as mortality rate and disability-adjusted life years (DALYs). Joinpoint regression model and age-period-cohort model were applied to analyze trends in the mortality rates of pneumoconiosis among Chinese males. Results From 1992 to 2021, the age-standardized DALYs rate, age-standardized years of life lost (YLLs) rate, age-standardized years lived with disability (YLDs) rate, and age-standardized mortality rate of pneumoconiosis among Chinese men all showed a downward trend, with average annual percentage changes (AAPC) of −2.63%, −2.81%, −0.87%, and −2.56%, respectively (P<0.05). Among the four types of pneumoconiosis, the disease burden of silicosis was the highest. The age-standardized mortality rates for silicosis, asbestosis, coal worker’s pneumoconiosis, and other types of pneumoconiosis had AAPC of −2.18%, −1.24%, −3.81%, and −3.21% (P<0.05), respectively. The age effects showed mortality rates for all types increased with age, particularly in silicosis and coal worker’s pneumoconiosis. The period effects showed a general decline in mortality risk, though silicosis remained significantly higher than other types. The cohort effects indicated that later birth cohorts had progressively lower mortality risks. Conclusion From 1992 to 2021, the burden of pneumoconiosis among Chinese males has shownsome alleviation; however, pneumoconiosis remains China’s most severe occupational disease. Given that males are the primary affected group in both incidence and mortality, continued attention and targeted preventive measures are essential. Effective control strategies should be tailored to address the specific characteristics of each type of pneumoconiosis.

ObjectiveTo observe the clinical efficacy and safety of hot ironing with Haitongpi Formula （海桐皮方， HF） in the treatment of lumbar disc herniation （LDH） of cold-dampness obstruction type. MethodsA total of 70 patients with cold-dampness obstruction type LDH were randomly divided into a treatment group and a control group， with 35 cases in each group. Both groups received three movements technique of Qinggong Spinal Manipulation （QSM） as the basis for treatment. In addition， the treatment group received hot ironing with HF， while the control group applied Diclofenac Sodium Gel externally. The treatment duration for both groups was 14 days. The clinical efficacy was compared between groups. Japanese Orthopedic Association （JOA） score， visual analog scale （VAS） for pain， pain pressure threshold （PPT） for lumbar positive response points， and traditional Chinese medicine （TCM） symptom scores were compared， on day 7， and day 14 of treatment， as well as on day 7 and day 14 of follow-up. The lumbar curvature index （LCI） was also compared before treatment and on day 14 of treatment. Adverse reactions during the study were recorded for both groups. ResultsA total of 35 patients in the treatment group and 34 patients in the control group were included for final analysis. The clinical total effective rate of the treatment group （91.43%， 32/35） was significantly higher than that of the control group （82.35%， 28/34， P＜0.05）. Both the JOA score and PPT of the two groups increased on day 7 and day 14 of treatment， and on day 7 and day 14 of follow-up. VAS scores and TCM symptom scores both decreased. The LCI of both groups increased on day 14 of treatment （P＜0.01）. Compared with the control group at the same time points， on day 14 of treatment and day 7 and day 14 of follow-up， the treatment group had higher JOA scores and PPT， and lower VAS scores and TCM symptom scores. The LCI of the treatment group increased on day 14 of treatment （P＜0.05 or P＜0.01）. One case in the control group showed mild skin allergy， with no other adverse reactions observed in either group. ConclusionBased on three movements technique of QSM， hot ironing with HF shows better clinical efficacy than external Diclofenac Sodium Gel in the treatment of cold-dampness obstruction type LDH. It can significantly reduce lumbar pain， increase pain pressure threshold， improve clinical symptoms， lumbar function， and lumbar curvature， with good safety.

Objective To explore whether the effect of urine-derived stem cells(USCs)on chondro-cytes in osteoarthritis(OA)is related to the PI3K/AKT pathway.Methods Human urine was collected aseptically,and primary USCs were isolated and cultured through specific steps.Meanwhile,chondro-cytes were extracted from the knee joints of Sprague-Dawley rats to establish the OA model.USCs were co-cultured with OA chondrocytes by using Transwell co-culture system,and the transcriptome changes of chondrocytes before and after co-culture were analyzed by using the high-throughput RNA sequencing.Moreover,the phosphorylation levels of key proteins of the PI3K/AKT/mTOR pathway were detected using protein immunoblotting,and the PI3K agonist 740 Y-P was employed to further vali-date the relationship between the protective effect of USCs on OA chondrocytes,as well as its possi-ble relationship to the PI3K/AKT pathway and the possible mechanism.Results Transcriptomic analysis showed that the protective effect of USCs on OA chondrocytes might be related to the'PI3K-Akt sig-naling pathway'.Protein level analysis confirmed that USCs significantly inhibited the PI3K/AKT/mTOR pathway in OA chondrocytes.Moreover,protein immunoblotting and immunofluorescence showed that USCs improved the expression of OA-related proteins and autophagy-related proteins in OA chondro-cytes.What's more,the inhibitory effect of USCs on the PI3K/AKT/mTOR pathway was partially re-versed by using the PI3K agonist 740 Y-P,while the protective and autophagy-promoting effects of USCs on OA chondrocytes were down-regulated.Conclusion This study reveals the potential protective effect of USCs on OA chondrocytes through inhibition of the PI3K/AKT/mTOR signalling pathway and its close correlation with improved autophagy.Therefore,it provides a research basis and theoretical support for the future application of USCs in the treatment of OA.

Objective:To investigate clinical curative effect of multiple composite tissues replantation with microsurgical technique in single hand.Methods:From May 2008 to December 2021, the clinical data of patients who underwent multiple composite tissue replantation in single hand in Chongming Hospital Affiliated to Shanghai University of Medicine & Health Sciences and Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, were retrospectively analyzed. According to the severed site, anatomical level, the injury cause, the severity of injury, the size of severed tissue, and replantation conditions (such as blood vessels for anastomosis), the severed tissue was evaluated and carried out modified classification (type Ⅰ-Ⅳ) before the operation, and the surgical plan was designed. The severed composite tissue was debrided in emergency, the severed bone and muscle tissue were fixed, and the arteries, veins and nerves were anastomosed by microsurgical technique under a high-power microscope. The ratio of arteries to veins was 1∶1-1∶2. If enough arteries and veins could not be found, arteriovenous shunt could be used to form arterial venous flap or venous arterialized flap, or form artery flap by just artery anastomosis, or form venous flap by just vein anastomosis. Then skin tissue was sutured after recanalization. After the operation, the patients received specialized treatment and guided rehabilitation exercise. The wound healing of hand, skin color, skin quality, swelling degree, sensation, pain degree of joint, and activity function were followed up after the operation. At the last follow-up, the patient’s self-evaluation of the treatment effect was divided into three levels: satisfactory, average, and unsatisfactory. One chief physician and one doctor-in-charge were responsible for the comprehensive evaluation of curative effect, according to the assessment standard for upper limb function issued by Chinese Medical Association of Hand Surgery. 80-100 points were excellent, 60-79 points were good, 40-59 points were fair, and <40 points were poor.Results:A total of 94 severed composite tissues in 35 patients, including of 20 male patients and 15 female patients were enrolled. The average age was 36.4 years (range, 16-65 years). Fifty severed tissues in 18 cases were classified into type Ⅰ, 40 severed tissues in 15 cases type Ⅱ, 4 severed tissues in 2 cases type Ⅲ. Among the 35 cases, 1 case of thumb pulp severed tissue was necrotic at the edge (0.3 cm×0.5 cm) due to local contusion, 1 case of index finger lateral severed tissue was necrotic at the edge (0.3 cm×0.8 cm) due to local avulsion injury, and healed after dressing change, and the other replanted composite tissue survived. The patients were followed up for 3 to 65 months (average, 18.5 months). The wounds were completely healed, and the color, elasticity, and quality of the replanted tissue was close to the surrounding normal skin. There was no obvious swelling or atrophy deformity of the hands. According to the patients’ self-assessment, 31 cases were satisfied and 4 cases were average. Comprehensive evaluation of hand function and appearance: excellent in 23 cases, good in 9 cases, fair in 3 cases, excellent and good rate was about 91.4% (32/35).Conclusion:Though multiple composite tissues replantation with microsurgical technique in single hand is difficult, and vascular anastomosis technical requirement is high, once surgery succeeds, the function and appearance can get good recovery, and patient satisfaction is also relatively high.
