BACKGROUND:At present,it is found that both Chinese medicine for activating blood circulation and removing blood stasis and platelet-rich plasma technology can repair damaged blood vessels,promote vascular regeneration,rebuild blood supply in the femoral head,restore normal blood supply,and further promote osteogenesis.Both of them have certain advantages in early intervention of steroid-induced necrosis of femoral head.It can also further understand the mechanism of blood activating and stasis removing herbs and platelet-rich plasma technology in improving steroid-induced necrosis of the femoral head,and provide new ideas for future treatment. OBJECTIVE:To review the research progress of the mechanism of the combination of blood activating and blood stasis removing herbs and platelet-rich plasma technology on steroid-induced necrosis of the femoral head according to the related literature at home and abroad. METHODS:PubMed,Web of Science,Metstr,CNKI and WanFang databases were searched for relevant articles."Traditional Chinese medicine,signal pathways,steroid induced necrosis of femoral head,vascular endothelial growth factor,platelet rich plasma"were used as the Chinese and English search terms separately.The time limit for searching the literature was from January 2000 to July 2022,and 75 related articles were finally included. RESULTS AND CONCLUSION:Both Chinese medicine for activating blood circulation and removing blood stasis and platelet-rich plasma technology have certain advantages in intervening the early stage of steroid-induced necrosis of femoral head.For traditional Chinese medicine,both single and compound drugs can effectively alleviate the further development of steroid-induced necrosis of the femoral head.The specific mechanism is as follows:(1)The traditional Chinese medicine for activating blood circulation and removing blood stasis has a significant anticoagulation effect,which can antagonize the abnormal(hypercoagulable)state of blood caused by hormone drugs,and further restore the normal blood supply in the femoral head.(2)Traditional Chinese medicine for activating blood circulation and removing blood stasis can repair damaged vascular endothelium,regenerate blood vessels and remodel blood supply in the femoral head by activating vascular endothelial growth factor.(3)The traditional Chinese medicine of promoting blood circulation and removing blood stasis has the obvious effect of removing blood stasis,which can reduce the accumulation of fat cells in the bone marrow cavity and relieve the pressure in the femoral head.(4)Traditional Chinese medicine for promoting blood circulation and removing blood stasis can regulate relevant signal pathways,maintain bone metabolism,promote the differentiation and balance of osteoblasts and osteoclasts,and effectively reduce steroid-induced necrosis of the femoral head.In addition,platelet-rich plasma contains a large amount of high concentration of cell growth factor,which plays a positive role in osteogenesis and vascular regeneration,and can also improve the abnormal state of the blood.Traditional Chinese medicine for activating blood circulation and removing blood stasis combined with platelet-rich plasma technology can play their biological roles,and the intervention effect is more significant.

Purpose::To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.Methods::A total of 282 healthy young male volunteers aged 18 -20 years participated in this cohort study. Injury location, degree, and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries. The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly. The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5, 50, 100 and 200 kHz to obtain 4 impedance values. The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution. Data of normal distribution were shown as mean ± SD and analyzed by t-test, while those of non-normal distribution were shown as median (Q 1, Q 3) and analyzed by Wilcoxon rank sum test. The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy. Results::Among the 282 subjects, 78 (27.7%) developed training injuries. Lower extremity training injuries revealed the highest incidence, accounting for 23.4% (66 cases). These patients showed higher percentages of lean body mass ( p = 0.001), total body water (TBW, p=0.006), extracellular water ( p=0.020) and intracellular water ( p=0.010) as well as a larger ratio of basal metabolic rate/total weight ( p=0.006), compared with those without lower extremity muscle injuries. On the contrary, the percentage of body fat ( p=0.001) and body fat mass index ( p=0.002) were lower. Logistic regression analysis showed that TBW percentage > 65.35% ( p=0.050, odds ratio =3.114) and 3rd space water > 0.95% ( p=0.045, odds ratio =2.342) were independent risk factors for lower extremity muscle injuries. Conclusion::TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower extremity muscle injuries in young males following training.

Objective: To explore the value of catheter-based adrenal ablation in treating Cushing's syndrome (CS)-associated hypertension. Methods: A clinical study was conducted in patients with CS, who received catheter-based adrenal ablation between March 2018 and July 2023 in Daping Hospital. Parameters monitored were blood pressure (outpatient and 24-hour ambulatory), body weight, clinical characteristics, serum cortisol and adrenocorticotropic hormone (ACTH) at 8 am, 24-hour urinary free cortisol (24 h UFC), fasting blood glucose and postoperative complications. Procedure effectiveness was defined as blood pressure returning to normal levels (systolic blood pressure<140 mmHg (1 mmHg=0.133 kPa) and diastolic blood pressure<90 mmHg), cortisol and 24 h UFC returning to normal and improvement of clinical characteristics. The parameters were monitored during follow up in the outpatient department at 1, 3, 6, and 12 months after catheter-based adrenal ablation. Results: A total of 12 patients (aged (40.0±13.2) years) were reviewed. There were 5 males, with 5 cases of adenoma and 7 with hyperplasia from imaging studies. Catheter-based adrenal ablation was successful in all without interruption or surgical conversion. No postoperative complication including bleeding, puncture site infection, adrenal artery rupture or adrenal bleeding was observed. The mean follow up was 28 months. Compared to baseline values, body weight declined to (59.48±11.65) kg from (64.81±10.75) kg (P=0.008), fasting blood glucose declined to (4.54±0.83) mmol from (5.53±0.99) mmol (P=0.044), outpatient systolic blood pressure declined to (128±21) mmHg from (140±19) mmHg (P=0.005), diastolic blood pressure declined to (78±10) mmHg from (86±11) mmHg (P=0.041), and the mean ambulatory daytime diastolic blood pressure declined to (79±12) mmHg from (89±8) mmHg (P=0.034). Catheter-based adrenal ablation in 8 patients was defined as effective with their 24 h UFC significantly reduced after the procedure (1 338.41±448.06) mmol/L from (633.66±315.94) mmol/L, P=0.011). The change of 24 h UFC between the effective treatment group and ineffective group was statistically significant (P=0.020). The postoperative systolic blood pressure in the treated adenoma group was significantly lower than those of hyperplasia group (112±13) mmHg vs. (139±20) mmHg, P=0.026). Conclusions: For patients with CS-associated hypertension who are unwilling or unable to undergo surgical treatment, catheter-based adrenal ablation could improve the blood pressure and cortisol level. Catheter-based adrenal ablation could be a safe, effective, and minimally invasive therapy. However, our results still need to be validated in further large-scale studies.

Background: Disrupted circadian rhythms have been associated with the development of irritable bowel syndrome (IBS). In some IBS patients, the symptoms may present with circadian fluctuations. Enterochromaffin cells (EC cells) and tryptophan hydroxylase 1 (TPH1) - 5 - hydroxytryptamine (5 - HT) signaling pathway are currently recognized as the key pathophysiological mechanism of IBS. Aims: To explore whether Bmal1, the core circadian clock gene, is involved in the occurrence of IBS by regulating TPH1-5-HT signaling pathway in EC cells. Methods: Normal Sprague-Dawley (SD) rats and IBS-model SD rats, as well as wild type (WT) and intestine-specific Bmal1 knockout (Bmal1

Pancreatitis is one of the most common inflammatory diseases of the pancreas caused by autodigestion induced by excessive premature protease activation. However, recognition of novel pathophysiological mechanisms remains a still challenge. Both genetic and environmental factors contribute to the pathogenesis of pancreatitis, and the gut microbiota is a potential source of an environmental effect. In recent years, several new frontiers in gut microbiota and genetic risk assessment research have emerged and improved the understanding of the disease. These investigations showed that the disease progression of pancreatitis could be regulated by the gut microbiome, either through a translocation influence or in a host immune response manner. Meanwhile, the onset of the disease is also associated with the heritage of a pathogenic mutation, and the disease progression could be modified by genetic risk factors. In this review, we focused on the recent advances in the role of gut microbiota in the pathogenesis of pancreatitis, and the genetic susceptibility in pancreatitis.
