Objective To evaluate the consistency of multi-slice spiral CT (MSCT), Digital Radiography (DR) and fat-suppression MRI in detecting occult knee joint injury. Method Clinical data from 150 patients with suspected occult knee injuries who presented to the Department of imaging at the General Hospital of Ordnance Industry between August 2022 and August 2023 were retrospectively reviewed. All patients underwent MSCT, DR, and fat-suppression MRI for diagnostic evaluation. Arthroscopic or surgical findings served as the gold standard. We analyzed and compared the detection rates of specific types of occult knee injuries (ligament, meniscus, occult fracture, etc.) across the three modalities, as well as their ability to assess the degree of collapse and horizontal displacement in patients with knee fractures, and their overall diagnostic performance. Result According to the gold standard, among the 150 patients with suspected occult knee injury, 103 tested positive and 47 negative. Statistically significant differences were observed among MSCT, DR, and fat-suppression MRI in detecting occult fractures(P<0.05). The detection rates ranked in descending order asfollows: fat-suppression MRI>MSCT>DR. However, no significant difference were found in the detection rates of joint effusion and patellar cartilage injuries among the three techniques (P>0.05). Statistically differences were also note among the three techniques in detecting the degree of collapse and horizontal displacement in patients with knee fractures (P<0.05). Specifically fat-suppression MRI identified a higher proportion of grade 1 and 2 lesions than both MSCT and DR. Statistically significant differences were observed among the three techniques in diagnostic sensitivity and accuracy for occult knee injuries (P<0.05). Fat-suppression MRI demonstrated superior sensitivity (99.03%) and accuracy (96.67%) compared with MSCT (75.73%, 79.33%) and DR (61.17%, 68.00%). However, no significant difference was found in diagnostic specificity among the three techniques (P>0.05). Conclusion Compared with MSCT and DR, fat-suppression MRI offers higher diagnostic sensitivity and accuracy for occult knee injuries, particularly in identifying ligament injuries, meniscus injuries, and occult fractures.

Cardiovascular diseases （CVD），a group of common diseases in clinical practice，are witnessing a steady rise in both incidence and mortality rates，posing a challenge to public health. Gualou Xiebai Banxiatang，originating from Synopsis of the Golden Chamber （《金匮要略》），was initially used to treat severe cases of chest impediment. The formula consists of Trichosanthis Fructus，Allii Macrostemonis Bulbus，Pinelliae Rhizoma，and Baijiu. It has a wide range of clinical applications，with therapeutic effects including moving Qi to relieve depression，activating Yang to dissipate mass，and expelling phlegm to alleviate chest congestion. In recent years，clinical research has confirmed that Gualou Xiebai Banxiatang，with or without modification，used alone or in combination with Western medicine，has definite effects in the treatment of CVD such as hyperlipidemia，coronary atherosclerotic heart disease，hypertension，heart failure，and arrhythmia. It can alleviate disease symptoms and reduce the risk of re-hospitalization. Basic research indicates that the mechanisms of Gualou Xiebai Banxiatang include improving endothelial functions，exhibiting anti-inflammatory properties，countering oxidative stress，preventing apoptosis，inhibiting ventricular remodeling，regulating mitochondrial functions，improving hemorheology，and modulating autophagy and neurotransmitters. This article reviews relevant articles in recent years with focuses on the compatibility，clinical application，and mechanism of Gualou Xiebai Banxiatang. This review is expected to provide a theoretical basis for the mechanism research and clinical application of this formula in treating CVD and to offer ideas and reference for in-depth research.

ObjectiveTo investigate the effect of Naoqingtong decoction （NQT） on the kidney damage and the inflammatory factors NOD-like receptor protein 3 （NLRP3）， apoptosis-associated speck-like protein containing a C-terminal caspase recruitment domain （ASC）， cysteinyl aspartate-specific proteinase-1 （Caspase-1）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） in spontaneously hypertensive rats （SHRs）. MethodsTwenty-four SHRs were randomized into a model group， a low-dose （12.9 g·kg^-1·d^-1） NQT （NQT-L） group， a high-dose （25.8 g·kg^-1·d^-1） NQT group （NQT-H）， and a captopril （CTP， 20 mg·kg^-1·d^-1） group， with 6 rats in each group. In addition， 6 homozygous male Wistar-Kyoto rats were used as the control group. The control and model groups were administrated with the same amount of normal saline by gavage for 8 weeks. General behaviors of rats were observed during the intervention period， and the blood pressure was measured periodically. At the end of intervention， the body mass was weighed， and both kidneys were collected and weighed for the calculation of the renal index. Hematoxylin-eosin staining was performed to observe the pathological changes in the kidney tissue. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were employed to determine the expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue. ResultsDuring the experiment period， the control group had normal mental status， food intake， and activity， while the model group showed thinning of hair， loss of luster， reduced activity， loss of appetite， fecal adhesion， and irritability， and some of the skin had scratches or blood scabs. The above symptoms were alleviated to different degrees after 8 weeks of NQT administration. An intelligent non-invasive sphygmomanometer was used to measure the tail artery pressure of rats， which showed that the systolic and diastolic blood pressure of rats in the model group was higher than that in the control group （P<0.01）. Compared with the model group， drug interventions lowered the systolic and diastolic blood pressure （P<0.05， P<0.01）. Compared with the control group， the model group showed severe pathological damage in the kidney tissue， which was alleviated in each drug intervention group. Compared with the control group， the model group showed up-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. Compared with the model group， the drug intervention groups showed down-regulated expression levels of NLRP3， ASC， Caspase-1， IL-6， and TNF-α in the kidney tissue （P<0.05， P<0.01）. ConclusionNQT can lower the blood pressure in SHRs by inhibiting the activation of NLRP3 inflammasomes， suppressing renal inflammation， and ameliorating hypertensive kidney damage.

This study was performed to investigate the inhibitory effects of Xuebijing injection(XBJ)on lipopolysaccharide(LPS)-induced inflammatory signals on EA.hy926 vascular endothelial cells and the underlying mechanism,and to provide a theoretical basis for the treatment of sepsis with XBJ.WST-1 assay was used to detect the effects of XBJ on the cell viability;Western blot analysis was performed to detect the protein expression levels of IκBα,p-p65,p-ERK,p-JNK,p-p38,p-AMAD17 in cell lysates and the content of sTLR4 fragment in the concentrated culture supernatants.ADAM17 sheddase activity in cells was detected by using a commercial available kit.Data showed that all of the TLR4-mediated inflammatory signals were significantly inhibited by the treatment of XBJ(P＜0.01).ADAM17 phosphorylation and shedding activity were induced by XBJ treatment,simultaneously the sTLR4 contents in the culture media were increased.XBJ-induced shedding of TLR4 was suppressed by the preteatment of 10 μmol/L TAPI-1(an ADAM17 inhibitor).Taken together,XBJ can induce the shedding of TLR4 from cell membrane by up-regulating ADAM17 shedding activity,thereby inhibiting the activation of TLR4-mediated intracellular inflammatory signals in EA.hy926 cells.

Objective:To provide reference for clinical diagnosis and treatment of hepatic cystic echinococcosis by analyzing the clinical characteristics of these patients.Methods:Clinical data of 15 patients with hepatic cystic echinococcosis hospitalized in the Second Hospital of Lanzhou University from April 22, 2019 to March 5, 2022 were collected. The general data, clinical manifestations, abdominal imaging results, treatment and outcome of the included patients were retrospectively analyzed.Results:The age of 15 patients with hepatic cystic echinococcosis ranged from 39 to 78 years, with a median age of 51 years. Among the 15 patients, 12 were farmers, two were freelance workers, and one was unknown. Eleven patients presented with abdominal pain and fatigue, one patient presented with obstructive jaundice, and three patients whom were found by physical examination did not complain of obvious discomfort. Echinococcoid cysts were located at the right lobe of the liver in eight patients, at the left lobe of the liver in five patients, and with multiple lesions in the left and right lobes of the liver in two patients. Two patients received conservative therapy. All the 13 patients who received surgical treatment recovered without complications, such as biliary fistula and subphrenic infection. The clinical symptoms including abdominal pain and fatigue were relieved significantly after surgery. The hospital stay were four to 23 days. All patients were administrated with albendazole (400 mg once daily).Conclusions:Hepatic cystic echinococcosis is more common in the right lobe of the liver, with atypical clinical symptoms. Preoperative imaging diagnosis and postoperative pathological examination are necessary for diagnosis. Surgery is the most effective treatment at present, and albendazole should be taken regularly in all patients.

Osteonecrosis of the femoral head （ONFH） is a painful and debilitating disease caused by impaired blood supply to the femoral head and cellular and tissue degeneration， leading to gradual destruction of the bone structure and progressive collapse of the femoral head. The main pathological mechanism of ONFH is the disruption of the balance between bone absorption and the reconstruction of new bone， resulting from microcirculation damage and decreased cellular tissue ability. This imbalance leads to biomechanical changes and accelerates the pathological progression of ONFH. In the early stages， clinical manifestations may not be obvious， mainly presenting as pain or discomfort in the hip or groin area， which can be relieved after rest. In the later stage of the disease， pain intensifies， and limb shortening， lower limb weakness， difficulty walking， or limping may occur. Currently， western medicine commonly uses osteogenic agents， anticoagulants， and artificial joint replacement for treatment， but there are also many issues such as prosthesis loosening and infection. Research has shown that traditional Chinese medicine （TCM） treatment of ONFH takes a holistic approach and employs multi-functional， multi-target， and multi-system Chinese medicine therapies， ensuring the safety and effectiveness of the treatment. The osteoprotegerin （OPG）/receptor activator of nuclear factor-κB （RANK）/RANK ligand （RANKL） signaling pathway plays a crucial role in maintaining the dynamic balance of bone remodeling. TCM treatments utilize this pathway to promote apoptosis of osteoclasts， reduce bone resorption， and accelerate bone formation， thereby playing an important role in the prevention and treatment of ONFH. This paper reviewed the role of OPG/RANK/RANKL signaling pathway and related cytokine expression in ONFH by reviewing relevant literature in China and abroad and research status of Chinese medicinal monomers， Chinese medicinal formulations， and combinations with physical therapy in increasing osteoblast secretion， promoting OPG expression， enhancing cytokine expression levels， and inhibiting osteoclast activity for the prevention and treatment of ONFH. This paper is expected to provide new ideas and directions for TCM in the prevention and treatment of ONFH.
