1.On exploration on medical equipment repair strategies
China Medical Equipment 2013;(9):82-83
Objective: To explore the troubleshooting of medical equipment and ensure its function and performance in daily work in hospital. Methods: According to the fault degree, equipment important degree, time and funds the difference, we should adopt different repair method. Results:Medical equipment fault is varied. The repair method depends on the repair time, repair funds for various reasons, we should according to the specific situation, weigh the advantages and disadvantages before making a decision. Conclusion:Medical equipment repair involves many factors. Leadership should be aware of the engineering and technical personnel in the hospital daily work, improve the level of engineering and technical personnel, in order to safeguard the medical equipment intact rate and meet needs.

A novel system is proposed to control the liquid nitrogen cooling and radio frequency heating of tissue to achieve effective thermal ablation in the treatment using fuzzy logic controller and fuzzy logic PID type controller separately. Results of ex-vivo pig liver experiments demonstrate that this system is useful and could p control the desired treatment procedure.

3.Selection of antiviral drugs for patients with hepatitis B virus-associated hepatocellular carcinoma
Journal of Clinical Hepatology 2022;38(11):2452-2456
Hepatitis B virus (HBV) infection is a key risk factor for the development and progression of hepatocellular carcinoma (HCC) and it promotes the progression of HCC by inducing liver fibrosis, genetic and epigenetic alterations, and the expression of active virally encoded proteins. Many studies have confirmed the influence of viral status on the prognosis of HCC, and effective antiviral therapy can help prevent or delay the recurrence of HBV-associated HCC, increase the overall survival time of patients undergoing radical or systemic, and improve the prognosis after multimodality therapy. Therefore, correct selection of antiviral drugs is crucial for the antiviral treatment of patients with HBV-associated HCC. This article briefly reviews the selection of antiviral drugs for patients with HBV-associated HCC, so as to provide a reference for clinical practice.

Objective To investigate the safety,feasibility and clinical application effect of upper arm totally implantable venous access port (TIVAP) inserted by the combination of oncologists and nurses in patients with tumor.Methods A total of 34 patients,who needed long-term transfusion treatment,were included in this study with upper arm TIVAP from March 2017 and December 2017.There were 20 males and 14 females.The median age was 63 (35 ~ 83) years.Upper arm TIVAP was implanted by both doctors and nurses into the patients with tumor,and the TIVAP related success rate,complications and patients satisfaction were recorded.Results 34 patients all succeeded in TIVAP implantation with the operation success rate of 100%.The average operation time was about 40 minutes (30 to 60 minutes) from the disinfecting cloth to the end of the suture.The operations of all patients were successful.After the operation two patients died of cancer progression,one patient had soft tissue infection around capsular bag,None of the patients had other complications such as blocked infusion,catheter shift,port reversal,and so on,and the incidence of complication was 2.94% (1/34).Conclusions Upper arm TIVAP has the advantages of safe puncture,shorter operation time,few intra-operative and post-operative complications and higher feasibility for operation by both oncologist and nurse,which can supplement the limitations and deficiencies of the chest wall port and PICC in a certain extent,therefore is a good choice for clinical application.

Objective:
To investigate the efficacy and drug related adverse reactions of sorafenib and sunitinib as first-line tyrosine-kinase inhibitors (TKIs) for patients with metastatic renal cell carcinoma (mRCC) and analyze the clinical prognostic factor for survival.
Methods:
The data of 271 patients with metastatic renal cell carcinoma who had complete clinicopathological data were retrospectively analyzed, including 174 cases in sorafenib group and 97 cases in sunitinib group, to access patients′ overall survival (OS) and progression-free survival (PFS). Prognostic values of all characteristics were determined by using univariate and multivariate Cox regression models.
Results:
The objective response rates (ORR) of the sorafenib and sunitinib groups were 14.9% and 19.6%, respectively, and the disease control rates (DCR) were 85.1% and 88.6%, respectively. No significant difference was found between the sorafenib and sunitinib group in ORR (
