Objective:To compare the short-term efficacy of hip arthroscopic surgery assisted by platelet-rich plasma (PRP) and hip arthroscopy alone in the treatment of femoroacetabular impingement (FAI).Methods:A retrospective cohort study was performed on the clinical data of 133 FAI patients admitted to Fourth Medical Center of PLA General Hospital from January 2019 to January 2021. The patients included 86 males and 47 females, aged 19-71 years [(39.1±12.6)years]. A total of 67 patients were treated with hip arthroscopy alone (hip arthroscopy group), and 66 patients were treated with PRP after hip arthroscopy under ultrasound guidance (hip arthroscopy+PRP group). The two groups were compared before, at 12 months after surgery and at the last follow-up regarding the following items: Visual Analogue Scale (VAS), Modified Harris Hip Score, International Hip Outcome Tool-12 (iHOT-12), and Hip Outcome Score Activities of Daily Living Scale (HOS-ADL). The incidence rate of complications after surgery was compared between the two groups.Results:A total of 108 patients were followed up for 24-36 months [(28.5±3.8)months], while 25 patients were lost to follow-up because of withdrawal of consent, wrong telephone number, etc, including 11 patients (16.4%) in the hip arthroscopy group and 14 patients (21.2%) in the hip arthroscopy+PRP group. The values of VAS in the hip arthroscopy group before, at 12 months after surgery and at the last follow-up were 5.00(5.00, 7.00)points, 3.00(2.00, 3.75)points, and 1.00(0.00, 2.00)points, respectively; the values of Modified Harris Hip Score were 49.00(39.00, 57.00)points, 76.00(69.25, 82.00)points, and 86.00(82.00, 88.00)points, respectively; the values of iHOT-12 were 0.45(0.28, 0.58)points, 0.69(0.58, 0.80)points, and 0.81(0.70, 0.92)points, respectively; the values of HOS-ADL were 0.52(0.42, 0.68)points, 0.87(0.75, 0.93)points, and 0.93(0.86, 0.99)points, respectively. The scores of VAS in the hip arthroscopy + PRP group before, at 12 months after surgery and at the last follow-up were 6.00(5.00, 7.00)points, 3.00(2.00, 3.75)points, and 1.00(0.00, 2.00)points, respectively; the values of Modified Harris Hip Score were 46.50(37.00, 56.75)points, 78.00(72.00, 84.00)points, and 84.50(82.00, 88.00)points, respectively; the values of iHOT-12 were 0.42(0.26, 0.51)points, 0.66(0.58, 0.74)points, and 0.81(0.68, 0.88)points, respectively; the values of HOS-ADL were 0.54(0.38, 0.65)points, 0.87(0.72, 0.96)points, and 0.94(0.86, 1.00)points, respectively. In both groups, VAS, Modified Harris Hip Score, iHOT-12, and HOS-ADL were significantly improved at 12 months after surgery and at the last follow-up compared with those before surgery, and were further improved at the last follow-up compared with those at 12 months after surgery (all P<0.01). There were no significant differences in VAS, Modified Harris Hip Score, iHOT-12 and HOS-ADL between the two groups before, at 12 months after surgery and at the last follow-up (all P>0.05). There was no significant difference in the incidence rates of postoperative hip pain and clicking between the two groups (both P>0.05). Conclusion:Hip arthroscopy can considerably improve short-term hip symptoms and function in FAI patients, but the use of PRP treatment after hip arthroscopy cannot further improve its short-term efficacy in FAI patients.

Brucellosis can lead to pathological changes of multiple systems. Capillary leak syndrome (CLS) is a clinical syndrome caused by different reasons, mainly characterized by hypotension, hypoproteinemia and systemic edema. The condition is critical and the clinical manifestations are complex, and multiple organ dysfunction syndrome (MODS) may occur in severe cases. CLS caused by brucellosis is extremely rare. The diagnosis and treatment of a patient with brucellosis complicated with CLS and MODS was analyzed in this paper, in order to improve the knowledge of clinicians about brucellosis and its complications.

Objective:To investigate the mechanism of interleukin-6 (IL-6) /signal transducers and activators of transcriptional 3 (STAT3) /helper T cell 17 (Th17) signaling pathway in lung injury of rats with sepsis intervened by forsythia, with a view to provide experimental basis for the role and mechanism of forsythia in the treatment of sepsis.Methods:In July 2021, 30 healthy Wistar male rats were selected and randomly divided into sham operation group, model group and treatment group, with 10 rats in each group. The rat model of sepsis was established by cecal ligation and puncture. 2 h after recovery, the rats were given traditional Chinese medicine forsythia orally, twice a day at an interval of 12 h. The wet/dry mass ratio (W/D) of lung tissue was detected 24 h after surgery. The morphological changes of lung tissue were detected by HE staining. Flow cytometry was used to detect Th17 population in peripheral blood. The expression levels of IL-6 and interleukin-17A (IL-17A) in serum were determined by enzyme-linked immunosorbent assay. The mRNA expression levels of IL-17A and IL-6 in lung tissues were detected by reverse transcription-polymerase chain reaction. The expression levels of STAT3 and IL-17A in lung tissue were determined by Western blotting.Results:Compared with model group, the W/D of lung tissue in treatment group was decreased, and the difference was statistically significant ( P<0.05). HE staining of lung tissue showed that compared with the model group, the degree of lung lesion and injury was reduced in the treatment group. Compared with sham operation group, the proportion of Th17 cells in CD4 lymphocytes in peripheral blood of rats in model group was significantly increased ( P<0.05). Compared with model group, the proportion of Th17 cells in CD4 lymphocytes in peripheral blood of rats in treatment group was significantly decreased ( P<0.05). Compared with sham operation group, peripheral blood serum IL-6 and IL-17 of rats in model group were significantly increased ( P<0.05). Compared with model group, IL-6 and IL-17 in peripheral blood serum of rats in treatment group were decreased ( P<0.05). Compared with sham operation group, the expressions of IL-17A and IL-6 mRNA in lung tissue of model group were significantly increased ( P<0.05). Compared with model group, the expressions of IL-17A and IL-6 mRNA in lung tissue of rats in treatment group were significantly decreased ( P<0.05). Compared with sham operation group, the protein expressions of STAT3 and IL-17A in lung tissue in model group were significantly increased ( P<0.05). Compared with model group, the pritein expressions of STAT3 and IL-17A in lung tissue in treatment group were significantly decreased ( P<0.05) . Conclusion:Forsythia plays a role in alleviating lung injury by down-regulating the expressions of the signaling pathway IL-6/STAT3/Th17, which providing a new target for the treatment of sepsis induced lung injury.

The incidence of human brucellosis is on the rise worldwide. The disease can affect various systems. The clinical manifestations are complex and non-specific, and the diagnosis is difficult. Especially the clinicians in the non-epidemic areas have sporadic cases on the pest free areas. Lack of experience in diagnosis and treatment leads to misdiagnosis and mistreatment, which affects prognosis. This article reports on the epidemiology, clinical manifestations, laboratory tests and treatment of a patient with unexplained fever and brucellosis in our department in June 2019. Raise the attention of clinicians in non-epidemic areas to the disease and enhance people's awareness of protection in non-epidemic areas.

Septic shock is a pathological stage during the progress of sepsis. The mortality rate is high, and timely, standardized and comprehensive treatment is of great significance in reducing the mortality rate. At present, there are many domestic and international guidelines for the diagnosis and treatment of sepsis and septic shock. On this basis, China Association of Integrative Medicine Emergency Medicine Committee organized experts to collect evidence-based medical evidence and expert experience in the diagnosis and treatment by integrated Chinese and Western medicine, and referred to the Expert consensus on diagnosis and treatment of sepsis with integrated traditional Chinese and Western medicine published by China Association of Integrative Medicine Emergency Medicine Committee in 2013, developed Expert consensus on diagnosis and treatment of septic shock with integrated traditional Chinese and Western medicine. The consensus provided a "China approach" for the resolution of this worldwide problem. In the "China approach", the staging of septic shock is "longitude", and the "four syndromes and four methods" treatment thought is "latitude". Under the framework of interlaced latitude and longitude, we recommend a series of effective integrated Chinese and Western medicine treatment. The method embodies the wisdom of China and has certain guiding significance for the clinical treatment of septic shock.

Bullous pemphigoid is a chronic obstinate dermatological disease. Hormone is the main therapeutic method, but the disease course is rather long, relapse is frequently seen and difficult to be radically cured; many complications may occur such as pulmonary infection, etc. From traditional Chinese medicine (TCM) basic principal points of view "lung governing skin and hair" and "strengthen the body resistance to eliminate pathogenic factors", the author explored the TCM therapy of bullous pemphigoid. By using clearing away lung heat and invigorating lung qi as the main principles supplemented by invigorating spleen and kidney, eliminating phlegm and blood stasis for treatment of such disease, relatively satisfactory therapeutic results were obtained.

Idiopathic systemic capillary leak syndrome (ISCLS) is a rare disease, the clinical manifestation is increased acute episodic capillary leakage (SCL), leading to protein-rich fluid leakage from the blood vessels to the interstitial tissue space, resulting in progressive systemic edema, hypoproteinemia, hypotension, blood concentration and other clinical symptoms. Because of ISCLS frequent recurrences, high mortality, pathogenesis unclear and no definite treatment plan, it is extremely important to fully understand the disease to carry out early intervention to save the patients' lives. This article reviews the progress of ISCLS, including its disease onset characteristics, clinical features, pathological mechanism, diagnosis and treatment of ISCLS.
