ObjectiveTo investigate the effects of the combination of components from Tripterygii Radix et Rhizoma and Chuanxiong Rhizoma on rheumatoid arthritis fibroblast-like synoviocytes （RA-FLSs） and the underlying mechanism. MethodsRA-FLSs were grouped as follows： blank control， positive control （methotrexate）， Tripterygii Radix et Rhizoma components， Chuanxiong Rhizoma components， and components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma. The cell-counting kit-8 （CCK-8） assay was employed to the cell proliferation， invasion， and apoptosis. The levels of tumor necrosis factor （TNF）-α， interleukin （IL）-6， reactive oxygen species （ROS）， and malondiadehyde （MDA） in cells were measured. Western blot was employed to determine the protein levels of nuclear factor erythroid 2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， nuclear factor-kappa B （NF-κB） p65， phosphorylated inhibitory subunit of NF-κBα （p-IκBα）， cysteinyl aspartate-specific protease-3 （Caspase-3）， and B-cell lymphoma 2 （Bcl-2）. Real-time PCR was employed to determine the mRNA levels of Nrf2， HO-1， and NF-κB p65. ResultsThe cells in the groups of positive control， Tripterygii Radix et Rhizoma components， Chuanxiong Rhizoma components， and components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma were treated with 2.50 mg·L^-1 methotrexate， 0.20 mg·L^-1 triptolide + 0.20 mg·L^-1 celastrol， 5.00 mg·L^-1 ferulic acid + 20.00 mg·L^-1 ligustrazine， 0.20 mg·L^-1 triptolide + 0.20 mg·L^-1 celastrol + 5.00 mg·L^-1 ferulic acid + 20.00 mg·L^-1 ligustrazine， respectively. Compared with the blank control group， drug administration reduced the proliferation and invasion and increased the apoptosis of cells （P<0.01）， lowered the levels of TNF-α， IL-6， ROS， and MDA （P<0.01）， up-regulated the mRNA and protein levels of Caspase-3， Nrf2， and HO-1 （P<0.01）， and down-regulated the mRNA and protein levels of Bcl-2， NF-κB p65， and p-IκBα （P<0.01）. Compared with the Tripterygii Radix et Rhizoma components group， the combination of components from Tripterygii Radix et Rhizoma+Chuanxiong Rhizoma inhibited the proliferation and invasion （P<0.05） and promoted the apoptosis of RA-FLSs， up-regulated the mRNA levels of Nrf2 and HO-1 and protein levels of Nrf2 and Caspase-3 （P<0.05）， and down-regulated the protein levels of NF-κB p65 and p-IκBα （P<0.05）. ConclusionThe combination of components from Chuanxiong Rhizoma and Tripterygii Radix et Rhizoma can inhibit the proliferation and invasion and promote the apoptosis of RA-FLSs and alleviate oxidative stress and inflammation by inhibiting the NF-κB signaling pathway， activating the Nrf2/HO-1 pathway， and regulating the expression of Bcl-2/Caspase-3.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective: To systematically evaluate the efficacy and safety of CT-guided percutaneous lung puncture biopsy versus ultrasound-guided percutaneous lung puncture biopsy. Methods: Relevant domestic and foreign related databases such as PubMed, Web of Science, Cochrane Library, OVID, China Biology Medicine, VIP, Wanfang and CNKI databases were searched, the randomized controlled trial about the applications of CT-guided and ultrasound-guided percutaneous lung puncture biopsy were collected. After extracting the relevant data, a Meta-analysis was performed using RevMan 5.2 and Stata softwares. Results: Ten studies met the inclusion criteria, with a total sample size of 1 158 cases, of which 635 were CT-guided puncture biopsy and 523 were ultrasound-guided puncture biopsy. Meta-analysis showed that the difference of the success rate between the CT-guided group and the ultrasound-guided group was not statistically significant [97.48% (619/635) vs. 96.56% (505/523), RR= 1.01, 95% CI 0.99-1.03, P= 0.360]; the puncture diagnosis rate in the CT-guided group was lower than in the ultrasound-guided group, and the difference was statistically significant [92.44% (619/635) vs. 96.56% (505/523), RR= 0.97, 95% CI 0.94-0.99, P= 0.007]. The total incidence of complications after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [14.49% (92/635) vs. 9.56% (50/523), RR= 1.56, 95% CI 1.11-2.19, P= 0.010]; the incidence of pneumothorax after puncture in the CT-guided group was higher than that in the ultrasound-guided group, and the difference was statistically significant [11.50%(73/635) vs. 6.31% (33/523), RR= 1.77, 95% CI 1.17-2.68, P= 0.007]; the difference of the incidence of bleeding after puncture between the CT-guided group and the ultrasound-guided group was not statistically significant [2.99% (19/635) vs. 3.25% (17/523), RR= 1.08, 95% CI 0.59-1.98, P= 0.800]. Conclusions Both CT-guided and ultrasound-guided percutaneous lung puncture biopsy have good clinical diagnostic value. However, for the intrapulmonary masses shown by ultrasound, the ultrasound-guided lung puncture biopsy has a shorter operation time, lower cost, and higher safety.

Objective To explore the treatment of locally advanced pancreatic cancer(LAPC)by Nanoknife,and the demonstrations on contrast enhanced ultrasonography(CEUS)after the procedures. Methods Four patients were enrolled.Each of them was percutaneously inserted 3-5 Nanoknife electrodes to ablate the lesions with 2-3 sessions under the guidance of ultrasound.After the procedures,CEUS, contrast enhanced CT,contrast enhanced MRI or computed tomography angiography (CTA) were performed to assess the efficacy.Results All patients uneventfully were able to tolerate the high-voltage Nanoknife procedures.However,the endurable pain or discomfort in abdomen was complained.For one patient with obstructive jaundice and mild liver dysfunction,pancreatic amylase in serum increased slightly at the first day after treatment.Furthermore,C response protein in serum elevated,and biliary tract infection happened at the third day.Moreover,thromboses in portal and splenic vein were found at the seventh day.The survival time for all cases were 3-8 months.According to the findings of CEUS,a well-defined no contrast enhancement was detected at ablative zone for all the patients within one week.Yet, contrast enhancement was sporadically detected at the periphery in 3 patients 1-2 months late.Meanwhile, on contrast enhanced CT or MRI,an area of absent enhancement was also depicted at the ablation zone with heterogeneously decreased enhancement at periphery of the lesion.Base on CTA findings,local stenosis of splenic vein and superior mesenteric vein with varices of collateral vascularity were found in one patient at the fiftieth day,and superior mesenteric vein obstruction accompanied by varices of collateral vascularity was also found in another patient at the seventieth day.Conclusions For patients with LAPC,Nanoknife treatment is a safe and convenient procedure that can be percutaneously completed under the guidance of ultrasound.Along with enhanced CT,MRI or CTA,CEUS is a promising way to evaluate the efficacy of this procedure.

Objective: To investigate the regulation of JAK2 tyrosine kinase inhibitor ruxolitinib on extracellular matrix metalloproteinase (MMP in JAK2V617F positive myeloproliferative neoplasms (MPN) cells. Methods: ①Forty cases of newly diagnosed JAK2V617F positive MPN patients and 15 healthy volunteers as control in Baoding No.1 Hospital between January 2012 and December 2015 were enrolled in this study. JAK2V617F/JAK2 ratio was detected by real-time-PCR; the expression levels of phosphorylation protein tyrosine kinase 2 (p-JAK2) , MMP-2 and MMP-9 in pathological tissues of bone marrow were detected by immunohistochemistry. The bone marrow cells of JAK2V617F positive MPN patients were treated with ruxolitinib, then the migration ability and MMP-2, MMP-9 gene and protein expression levels were detected. ②The human erythroleukemia cell line HEL cells were treated with different concentrations of ruxolitinib (0, 50, 100, 250, 500, 1 000 nmol/L) . The cell viability was detected by CCK-8 test; cell migration ability was tested by transwell chambers. The mRNA expression levels of JAK2, MMP-2 and MMP-9 were detected by real-time-PCR. The protein expression levels of p-JAK2, MMP-2 and MMP-9 were detected by Western blot. Results: ①The expression levels of p-JAK2, MMP-2 and MMP-9 in the newly diagnosed group were significantly higher than control group respectively [ (78.56±24.55) % vs (41.59±17.29) %, P<0.05; (48.25±18.74) % vs (22.79±13.89) %, P<0.05; (53.29±19.28) % vs (15.56±14.96) %, P<0.05]. Spearman correlation analysis showed the positive correlation of MMP-2 and MMP-9 protein expression levels with JAK2V617F mutation (r=0.526, P=0.001; r=0.543, P=0.001) . ②The proliferation of HEL cells was inhibited by different concentrations of ruxolitinib in time and dose dependent manner. ③Cell migration test showed the number of cells leaked to the low chamber in MPN patients bone marrow cells and HEL cells treated with 5 nmol/L of ruxolitinib group were significantly lower than that without ruxolitinib treatment after 24 h [ (154.7±27.5) vs (320.3±67.3) , t=13.47, P<0.05; (70.7±10.5) vs (135.3±16.7) , t=13.89, P<0.05]. The mRNA and protein expression levels of JAK2, MMP-2 and MMP-9 decreased with the increased concentration of ruxolitinib. Conclusion Ruxolitinib inhibits MPN cell migration and expression of MMP-2 and MMP-9 via JAK2 signal pathway.

OBJECTIVE: To discuss management of chylous leakage after retroperitoneoscopic upper-pole heminephrectomy for duplex kidney. METHODS: Between November 2004 and Februar y 2011, 39 patients underwent retroperitoneoscopic upper-pole heminephrectomy for duplex kidney, of these 5 patients had chylous leakage. The ages of the patients ranged from 32 to 60 years (mean 42). All the patients were treated conservatively, and the therapeutic effects were observed. RESULTS: Delayed chylous leakage in 5 patients occurred 5-31 days after surgery, and leakage occurred in 4 of the same 5 patients during the first 2 post-operative years. Chylous leakage after retroperitoneoscopic upper-pole heminephrectomy for duplex kidney preferentially occurred at the left side of duplex kidney. All the patients healed under conservative treatment. CONCLUSION Chylous leakage typically occurs after left retroperitoneoscopic upper-pole heminephrectomy for duplex kidney, and can be prevented by improving surgical technique; it can be completely relieved by conservative management with satisfactory results.
