At present stage,the needs of practice personnel of medical law include‘professional personnel’ (master's degree)and ‘general personnel’(bachelor's degree),but the existing training system did not make any distinction between the two and triggered the following situations:practical teaching mode convergence,content inanition,lack of resources,etc. From the real needs of the com-munity,practice teaching in master stage should focus on vocational practical trainingcourse including mock trial,common medical law disputes,professional documents writing. Practice teaching in un-dergraduate stageshould focus on the primary practical trainingcourse including court records and medical dispute mediation.

OBJECTIVE: To investigate effect of crystallinity on in vitro and in vivo release behaviors of spherical self-assembly of Recombinant human interferon-alpha (rhIFN). METHODS: rhIFN can form spherical self-assembly by static crystallization method. The crystallinity was determined by X-ray to characterize molecular ordered degree of various spherical crystals. The drug dissolution in vitro and the pharmacokinetics in vivo of various rhIFN forms were further investigated. RESULTS: The spherical self-assembly of rhIFN in amorphous and crystalline forms were obtained through adjusting protein supersaturation during self-assembly process. The amorphous precipitates were characterized as recovery of 96.5% and mean diameter size of 0.6 μm. Two kinds of crystallized rhIFN were characterized as mono-dispersed spheres, with yield of ≤ 80%, mean diameter size of 10-20 μm. Their crystallinity was 23.2% and 30.8%, respectively. The dissolving rates of spherical self-assemblies were decreased significantly with increased crystallinity. After s.c. administration of spherical self-assembly of rhIFN in amorphous and crystalline forms, the peak time (tmax) were retarded from(6.00±1.40) h to (13.20±2.68) and (22.40±3.57) h, the corresponding half life (t1/2) were prolonged from (4.75±0.82) h to (10.68±1.97) and (29.17±4.93) h. CONCLUSION: The spherical self-assemblies of rhIFN in crystalline form can improve their release performance either in vitro or in vivo, which provide a new candidate for sustained delivery of therapeutic proteins.

Unlike conventional radiation therapy, stereotactic radiation therapy (SRT) is an emerging tumor-ablative radiation technology with a high-dose delivery to targets while dramatically sparing adjacent normal tissues. The strengths of SRT involve noninvasive and short-course treatment, high rates of tumor local control with a low risk of side effects. Although the scientific concepts of radiobiology fail to be totally understood currently, SRT has shown its potential and advantages against various tumors, especially for those adjacent to less tolerable normal organs (spinal cord, optic nerve, bowels, etc.). Nowadays, the clinical efficacy of SRT has been widely confirmed in certain patients, especially for those medically inoperable, unwilling to undergo surgery, medicine ineffective with tumor progression. Moreover, SRT could be properly used as palliative treatment aiming at relieving local symptoms and pain, and eventually achieving a potential survival benefit of several months. However, the weaknesses of SRT relate to inevitable radiation-induced toxicities as well as the inaccessibility of prophylactic irradiation. In general, one flaw cannot obscure the splendor of the jade. The emergence and development of SRT has opened the new era of precision radiation therapy, and SRT will probably step gloriously onto the remarkable stage for precision medicine.

Objective To investigate the characteristics and influencing factors leading to sudden cardiac death (SCD) of incarcerated prisoners. Methods Seventy-five SCD cases of prisoners between 2000 and 2013 in Henan province were collected, and environment, psychological and physical factors were retro-spectively analyzed. Combined with histopathological results, specific factors of SCD were also studied. Results In the 75 cases, 21 cases (28%) had definite chronic past medical histories, and 75 cases (100%) had cardiovascular disease confirmed by autopsy. Conclusion Due to presence of the potential cardiac diseases, special incarcerated environment, psychological stress, and body-restraint might be the precipitat-ing factors in SCD of those prisoners.

Targeted therapy has gradually become the focus in the treatment of tumor, with the emerge of more and more targeted drugs which has brought the treatment of tumor into a new era. Imatinib, the tyrosine kinase inhibitor, is one of the important types of targeted therapy, has become the standard of care in adjuvant therapy of gastrointestinal stromal tumor(GIST) with extraordinary effects. However, the questions are still on debate incluing the optimal way to evaluate treatment results, the treatment duration, whether it can be intermitted or not, second line therapy for imatinib-intolerance or -resistance and the combination with surgery.

Objective:To clarify the relationship between postoperative tumor recurrence and the type and dosage of immunosuppressants in patients undergoing liver transplantation.Method:A retrospective analysis was conducted on the clinical data of patients who underwent liver transplantation for liver cancer from September 2007 to January 2019 at the Department of Hepatobiliary Surgery, First Affiliated Hospital of Chongqing Medical University. According to whether there was tumor recurrence after liver transplantation, the patients were divided into the case group and the control group. The etiology, alpha-fetoprotein level, Child-Pugh score, model for end-stage liver disease (MELD) score, and cancer nodules, number of tumors, diameter of largest cancer nodule, microvascular infiltration (MVI), large vessel infiltration, Edmondson grade of tumor differentiation, postoperative immunosuppression regimen, and blood trough concentration of tacrolimus or cyclosporine were compared between the two groups. The effects of calcineurin inhibitor (CNI) exposure in groups of patients on tumor recurrence were compared, and statistically significant factors were included in the Cox regression analysis. Using the BCLC staging standard of liver cancer, all the subjects were stratified, and the influence of CNI exposure on tumor recurrence was further analyzed.Results:This study included 50 patients. There were 15 patients in the case group, aged (45.8±8.2) years, with 13 males (86.7%). There were 35 patients in the control group, aged (45.4±12.0) years, 31 males (88.6%). The diameter of the largest cancer nodule in the case group was significantly larger than that in the control group [(5.9±3.0) cm vs (3.5±1.8) cm, P<0.05]. The tacrolimus exposure levels in the case group at 14 d after operation were significantly higher than the control group[(11.7±7.7)ng/ml vs (5.9±3.0)ng/ml, t=2.48], 1 month after operation [(12.2±4.5) ng/ml vs (7.8±4.3) ng/ml, t=2.82], 9 months after operation [(6.9±4.0) ng/ml to (4.7±2.0) ng/ml, t=2.21] and the area under the curve at 1 year after operation [(100.1±21.1) vs (74.4±19.2), t=3.66], all P<0.05. Survival analysis showed that the cumulative tumor-free survival rate of the CNI high-exposure group was significantly lower than that of the CNI low-exposure group (52.2% vs 85.2%, χ 2=6.52, P<0.05). Multivariate analysis using the Cox proportional hazards regression model showed that the largest cancer nodule diameter ( RR=1.23, 95% CI: 1.01-1.60) and high CNI exposure ( RR=4.02, 95% CI: 1.10-14.74) were independent risk factors for tumor recurrence after liver transplantation. Stratified analysis showed that of the 17 patients with BCLC stage B, 6 patients (66.7%) with high CNI exposure developed tumor recurrence, while only 1 patient (12.5%) with low CNI exposure developed tumor recurrence. The difference was statistically significant ( P<0.05). Survival analysis showed that the cumulative tumor-free survival rate of patients with CNI high-exposure was significantly lower than that of patients with CNI low-exposure (33.3% vs 87.5%, χ 2=5.74, P<0.05). Of the 8 patients with BCLC stage C, 4 patients developed tumor recurrence with CNI high-exposure (100.0%). There was no tumor recurrence in patients with low CNI exposure. The difference between groups was statistically significant ( P<0.05). Survival analysis showed that the cumulative tumor-free survival rate of patients with high CNI exposure was significantly lower than that of low CNI exposure (0 vs 100.0%, χ 2=6.80, P<0.05). Conclusions:Tumor recurrence after liver transplantation was not significantly related to the type of immunosuppressant used. High CNI exposure was a risk factor for tumor recurrence after liver transplantation.

Objective To summarize our experience in choledochofiberscopic treatment for residual stones of biliary tract. Methods 1105 cases of residual stones of biliary tract diagnosed and treated with choledochofiberscope in the past 19 years were reviewed retrospectively. Results The 1067 patients with residual stones of bile duct were treated with choledochofiberscope for 1483 times altogether. The stones were completely removed in 1035 cases, while the stones were not cleared in other 32 cases. The clearance rate of residual stones was 97.0%(1035/1067). No patient died of choledochofiberscopic treatment. Conclusions Choledochofiberscopic treatment plays an important role in the treatment of residual stones of bile duct, because it not only reduces residual stones of bile duct to avoid repeated operation, but also has some advantages such as excellent safety, minimal invasion, low cost and quicker recovery.
