Objective:
To prospectively evaluate the feasibility, accuracy, and safety of multiparameter MRI-guided percutaneous biopsy using a 1T open MRI scanner for evaluating suspicious centrally located lung lesions with associated post-obstructive atelectasis.
Materials and Methods:
In this single-center study, MRI-guided percutaneous coaxial cutting biopsy was performed for 107 suspicious central lung lesions with associated post-obstructive atelectasis in 107 patients between July 2015 and December 2020. A fast T2-weighted imaging (T2WI)-turbo spin echo (TSE) sequence and an enhanced fast T1-weighted imaging (T1WI)-TSE sequence were used to identify, localize, and biopsy lung lesions, and diffusion-weighted imaging (DWI) was used as a supplementary sequence for identifying the lesion location. The final diagnosis was confirmed by surgical histopathology or clinical follow-up for a minimum of 24 months. The sensitivity, specificity, and accuracy for diagnosing lung malignancies were calculated, and the complications were recorded for each case.
Results:
Using multiparameter MRI, central lung lesions could be clearly distinguished from post-obstructive atelectasis in 96 patients (89.7%). The sensitivity, specificity, and accuracy of MRI-guided percutaneous biopsy for diagnosing lung malignancy was 97.0% (98/101), 100% (6/6), and 97.2% (104/107), respectively. Self-limited hemoptysis occurred in three patients. Pneumothorax occurred in five patients, of which none required pleural drainage. No serious procedure-related complications were observed.
Conclusion
As a technology that does not involve ionizing radiation, multiparameter MRI-guided percutaneous coaxial cutting biopsy is a safe and accurate diagnostic technique for evaluating centrally located lung lesions associated with post-obstructive atelectasis.

For Perihilar cholangiocarcinoma (pCCA), surgical resection is the only effective way to cure this disease. However, it has high postoperative mortality and high recurrence rate. Domestic and foreign scholars have constructed statistics-based evaluation methods to predict patients′ postoperative survival and complications, such as nomogram, scoring system and other prognostic models. Based on these methods, clinicians can better select patients who can benefit from surgery and choose the optimal? treatment for more severe patients. Through the adoption of other treatments or some ways to ameliorate some preoperative condition, to improve the patient′s mortality and survival. This article reviews the prognostic risk factors and prognostic models of pCCA in order to provide a reference for clinicians to predict the prognosis about the surgery.

Ankylosing spondylitis is an autoimmune disease with sacroiliac arthritis and spinal arthritis as the main manifestations.The disease mainly occurs in young men,has a high disability rate,and is a serious threat to the life and health of patients.Biological agents are expensive,and many adverse reactions to hormones,non-steroidal anti-inflammatory drugs,and anti-rheumatic drugs have been recorded.Traditional Chinese medicine can regulate the immunity and anti-inflammatory effects of the disease,and has good clinical effects.To promote the further study of the pathogenesis of ankylosing spondylitis and the development and screening of therapeutic drugs and therapies,in this paper,we summarize the method and mechanisms of modeling of the existing animal model of ankylosing spondylitis and analyze the advantages and disadvantages of the model.To evaluate the agreements between Chinese and Western medicine clinical characteristics,we compare the characteristics of Chinese and Western medical syndromes of the animal model.Building an animal model of ankylosing spondylitis with a higher degree of consistency between traditional Chinese and Western medicine is the key to innovative research into traditional Chinese medicine method of treating ankylosing spondylitis.To lay the foundation for research into traditional Chinese medicines and acupuncture for ankylosing spondylitis,this paper analyzes the degree of concurrence between the Chinese and Western medicine clinical characteristics of animal models.

Objective:To observe the inhibiting effects of manual acupuncture(MA)on bladder cell apoptosis in rats with diabetic neurogenic bladder(DNB)based on the protein and mRNA expression of B-cell lymphoma-leukemia(Bcl)-2,Bcl-2-associated X(Bax)protein,caspase-3,and the protein expression of α-smooth muscle actin(α-SMA),transforming growth factor(TGF)-β in the bladder tissue. Methods:A DNB rat model was established via intraperitoneal injection of streptozotocin(STZ).The rats were randomly divided into a control group,a model group,and an MA group,with 10 rats in each group.For the MA group,MA was applied after modeling.The body mass,fasting blood glucose(FBG),bladder wet weight,and bladder histomorphology were observed.Protein and mRNA expression levels of Bcl-2,Bax,and caspase-3 and the protein expression of α-SMA and TGF-β in the bladder tissue were determined.The apoptotic index of bladder cells was also evaluated. Results:After STZ injection,compared with the control group,the model group and the MA group both showed higher FBG from week 3 and lower body mass from week 9(P<0.05),and had a larger bladder wet weight(P<0.05).Compared with the model group,the MA group showed a smaller bladder wet weight(P<0.05).The histopathological evaluation indicated that MA improved muscle fiber alignment and detrusor cell compensatory hypertrophy in the bladder tissue.In addition,compared with the control group,the apoptotic index increased significantly in the model group and the MA group(P<0.05);the protein and mRNA expression levels of Bax and caspase-3 and the protein expression level of TGF-β in the bladder tissue in the model group and the MA group increased significantly(P<0.05),while the protein and mRNA expression levels of Bcl-2 and the protein expression level of α-SMA in the bladder tissue decreased significantly(P<0.05).Compared with the model group,the apoptotic index of the MA group decreased significantly(P<0.05);the protein and mRNA expression levels of Bax and caspase-3 and the protein expression level of TGF-β in the bladder tissue decreased significantly(P<0.05),while the protein and mRNA expression levels of Bcl-2 and the protein expression level of α-SMA in the bladder tissue increased significantly(P<0.05). Conclusion:MA can protect the bladder by inhibiting the excessive apoptosis of bladder cells,which may be related to the down-regulation of Bax and caspase-3 proteins and mRNAs and TGF-β protein expression,and the up-regulation of Bcl-2 protein and mRNA and α-SMA protein expression.
