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.

Objective:To evaluate the clinical efficacy of modified all-arthroscopic reconstruction of medial patella femoral ligament (MPFL) for the treatment of recurrent patellar dislocation.Methods:A retrospective case series study was conducted to analyze the clinical data of 38 patients (46 knees) with recurrent patellar dislocation, who were treated at First Affiliated Hospital of Shenzhen University from January 2017 to January 2020. The patients included 12 males (12 knees) and 26 females (34 knees), aged 14-40 years [(24.6±5.4)years]. All patients underwent the modified all-arthroscopic MPFL reconstruction procedure. The femoral tunnel locations were assessed by 3D-CT immediately after surgery. The MRI was performed at 6 and 12 months after operation to assess the healing morphology of the reconstructed MPFL. The Lysholm score and Kujala score were used to assess the knee function before operation, at 6 months after operation, at 12 months after operation and at the last follow-up. The time to return to sports as well as complications were observed.Results:All patients were followed up for 26-48 months [(32.4±8.6)months]. Postoperative 3D-CT examination showed that the femoral tunnels were located in the groove area of the medial epicondyle of the femur and the adductor tubercle. At 6 and 12 months after operation, MRI T2 images showed that the reconstructed MPFL had a low signal and well tensioned ligament tissue, indicating that the MPFL was healed well. The Lysholm scores at 6 and 12 months postoperatively and at the last follow-up were (81.1±12.0)points, (91.2±3.8)points, and (92.2±9.8)points, respectively, being significantly higher than the preoperative (52.4±10.6)points (all P<0.01). The Kujala scores at 6 and 12 months postoperatively and at the last follow-up were (85.4±3.9)points, (91.4±3.6)points, and (93.1±8.5)points, respectively, being significantly higher than the preoperative (55.2±6.8)points (all P<0.01). Compared with 6 months postoperatively, the Lysholm score and Kujala score were significantly improved at 12 months postoperatively and at the last follow-up (all P<0.05). All patients returned to sports, with the time to return to sports for 3-12 months [(8.7±2.3)months] after operation. One patient had poor wound healing but was healed after dressing changes. No wound infection, nerve injury, joint stiffness, patella re-dislocation or other complications occurred. Conclusion:For recurrent patellar dislocation, the modified all-arthroscopic MPFL reconstruction has advantages of accurate bone tunnel positioning, good ligament healing, good function recovery, early return to sports, and less postoperative complications.

ObjectiveTo investigate the clinical features of patients with hepatic myelopathy (HM) in China. MethodsThe articles on HM, published in China from January 2009 to December 2018, were collected to analyze the clinical features, laboratory examination results, diagnosis, treatment, and prognosis of HM patients. ResultsA total of 94 articles were included, with 562 patients in total, among whom there were 489 male patients and 73 female patients. Their age ranged from 17-81 years, with a mean age of 46.3±17.5 years. Hepatitis B cirrhosis was the most common etiology (64.4%), followed by alcoholic cirrhosis (10.3%) and hepatitis C cirrhosis (9.2%). The clinical manifestations of HM mainly included decline of muscle strength (89.50%), tendon hyperreflexia (76.87%), ataxia, and movement disorder (76.51%). Laboratory examination showed an increase in blood ammonia by 92.31% and a reduction in albumin by 88.96%. Imaging diagnosis mainly depended on electromyography (64.92%) and spinal cord MRI (22.82%), and abdominal color Doppler ultrasound, CT, or MRI alone has limited clinical value. After comprehensive medical treatment, no patient (0%) was cured, 106 patients (18.86%) were improved, 211 patients (37.54%) had no response, 31 patients (5.52%) worsened, 129 patients (22.95%) died, and 53 patients (9.43%) were not explained. A total of 39 patients underwent liver transplantation, with an improvement rate of 5641%. ConclusionHM is a rare complication of end-stage liver disease and is mainly observed in middle-aged men. It has the main manifestation of chronic and progressive spastic paraplegia of both lower limbs. Currently, there is no effective treatment method, and liver transplantation is feasible for some patients, with poor treatment response and poor prognosis.

Short-chain fatty acids (SCFAs) are important metabolic products of intestinal bacteria, and participate in the metabolism of intestinal materials, mediate the interaction between intestinal bacteria and intestinal mucosal epithelial cells, and are closely related to the occurrence of many diseases. Intestinal leakage is a pathological state and disease process in which intestinal function is impaired due to various reasons. Studies on the relationship between SCFAs and intestinal leakage are few. This article reviewed the relationship between SCFAs and intestinal leakage and its impact on diseases.

Objective: To investigate awareness of digestive system injury caused by corona virus disease 2019 (COVID-19) in gastroenterologists. Methods: From February 21 to 23 in 2020, the electronic questionnaire was sent out to explore the condition of the basic knowledge of COVID-19 and knowledge of digestive system injury caused by COVID-19 grasped by gastroenterologists. Chi-square test was used for statistical analysis. Results: A total of 2 216 gastroenterologists from 31 provinces, autonomous regions and municipalities nationwide completed the survey. 99.7% (2 209/2 216) of gastroenterologists stated that they had read the COVID-19 diagnosis and treatment guidelines. The percentage of physicians who well knew the diagnostic criteria of suspected and confirmed cases of COVID-19 was 34.9% (774/2 216) and 39.4% (874/2 216), respectively. The percentage of physician who gave the right answer of COVID-19 detectable methods and lung imaging was 68.4% (1 516/2 216) and 71.6% (1 586/2 216), respectively. The percentage of correct answer of digestive system injury caused by COVID-19 in residents, attending physicians, associate chief physicians and chief physicians was 30.9% (134/433), 33.9% (234/691), 32.4% (213/657) and 34.9% (152/435), respectively, however there were no statistically significant differences among physicians of different level (χ²=6.60, P> 0.05). 95.6% (2 119/2 216) of gastroenterologists believed that probiotics could effectively improve bowel function, and 94.0% (2 082/2 216) of gastroenterologists considered that enteral nutrition support could improve patients’ prognosis. Conclusions The knowledge and dynamic progress of the digestive system injury caused of COVID-19 are still insufficiently grasped by gastroenterologists in China. So it is necessary to carry out systematic and pertinent training for them.

At present, coronavirus disease 2019 (COVID-19) caused by 2019 novel coronavirus (2019-nCoV) infection has spread rapidly in China and more than 70 countries around the world and thus become a public health event of international concern. In addition to fever and respiratory symptoms, varying degrees of liver injury is also observed after 2019-nCoV infection. This article reviews the clinical features, pathology, pathogenic mechanism, and therapeutic strategies of liver injury associated with COVID-19, hoping to provide a reference for clinical decision-making on the prevention and treatment of COVID-19.

Objective To analyze the clinical and imaging features, surgical strategy and prognosis in patients with brainstem gangliogliomas (GG). Methods The clinical data of 46 patients with brainstem GG from February 2010 to August 2017 were retrospectively analyzed. The clinical and imaging features, surgical methods and prognosis were reviewed. Results The age of 46 brainstem GG patients was (22.5 ± 4.6) years, the duration was (38.1 ± 8.9) months, and the most common symptoms were dizziness and headache, accounting for 47.8％(22/46). The MRI results showed that endogeny type was in 5 cases, exogenesis type in 10 cases, and endogeny-exogenesis type in 31 cases. The exogenesis type was enrolled as non-infiltrate brainstem group (10 cases), and the endogeny type and endogeny-exogenesis type were enrolled as infiltrate brainstem group (36 cases). The axial T1WI showed that the crescent sign was in 20 cases (43.5％, 20/46), and the sagittal T1WI showed that the patching sign was in 31 cases (67.4％, 31/46). Among all patients, total resection was achieved in 13 cases, near total resection in 9 cases, subtotal resection in 16 cases, partial resection in 7 cases and biopsy in 1 case. No operative death occurred. The patients were followed up for 3 to 87 (40.6 ± 12.8) months, and 5 patients died (all in infiltrate brainstem group). The progression- free survival in non- infiltrate brainstem group was significantly longer than that in infiltrate brainstem group:(46.0 ± 13.1) months vs. (19.5 ± 8.9) months, and there was statistical difference (P<0.05). Conclusions Most brainstem GG has some unique MRI characteristics. Microsurgical resection might be preferred. Tumors that locate outside the brainstem can be fully removed. The long-term prognosis of brainstem GG is better.
