BACKGROUND: Combining drugs with materials using 3D printing technology can be formulated Into a dosage form with a specific release rate, which is better for clinical use. OBJECTIVE: To review the preparation technique, advantages and indications of pharmaceutical composites made from western medicine, traditional Chinese medicine, metal elements and Ions and related materials. METHODS: The first author used the search terms "Drug; Chinese medicine; Metal; Composite materials; 3D printing" to search the CNKI and Wanfang databases In Chinese and the PubMed and Web of Science in English to retrieve papers published during 1950-2019. A total of 339 papers were preliminarily retrieved. After screening, 46 papers were included in the final analysis. RESULTS AND CONCLUSION: Pharmaceutical composite materials made of western medicine, traditional Chinese medicine, metal elements and Ions and related materials have certain advantages in the pharmaceutical field and clinical use. It can not only improve the bioavailability of drugs, reduce toxic side effects, but also achieve a combination of drugs. In recent years, drug composite materials have been used In orthopedics, dentistry, cardiovascular medicine, otolaryngology and other fields, but its application is still in its Infancy. Many aspects need to be Improved, such as improving the quality of drug composites, Increasing mechanical stability, reducing the brittleness, printing the full-featured blood vessels and organs that fit the size of the human body, and better Imitating the biomechanics and tissue structure of human body.

Objective To investigate the change of Th22 cells in the peripheral blood of the patients with primary biliary cirrhosis (PBC) and evaluate its clinical significance. Methods The proportion of Th22 cells in the peripheral blood of PBC patients and healthy controls were evaluated by flow cytometry. The cytokine IL-22 of each group was measured by ELISA and ALT, AST, GGT, TBIL and CRP were measured by Automatic biochemical analyzer. The proportion of Th22 cells correlation with IL-22 , ALT, AST, GGT, TBIL and CRP were analyzed. Results The proportion of Th22 cells was higher in PBC patients than healthy controls (P < 0.05), Moreover the frequency of Th22 was increased in PBC patients with liver cirrhosis than in PBC patients with liver non-cirrhosis (P < 0.05). The level of IL-22, ALT, AST, GGT, TBIL and CRP were increased in PBC patients (P < 0.05). Moreover Th22 frequency of peripheral blood was positively associated with IL-22, ALT, AST, GGT and CRP (P < 0.05). Conclusion Th22 may be involved in the pathogenesis of and it is a potential therapy target for PBC.

This paper was aimed to study the safety of moxibustion with FMEA method.Failure mode and effects analysis (FMEA) were used in every aspect of the operation process of moxibustion.And the local skin temperature was measured in 80 patients treated with moxa box moxibustion.The results showed that the skin temperature reached the highest when the moxibustion was given for 15 min,which was in consistence with the patients' chief complaints and their tolerances.It indicated that moxibustion for 15 min was the best moxibustion amount.Meanwhile,inspection should be made to avoid burning.After the application of FMEA,the RPN of the inspection activities,the temperature and distance of moxibustion were significantly decreased (P ＜ 0.05).It was concluded that the application of FMEA management mode strengthened the risk management of moxibustion treatment,standardized treatment process,provided the basis for the temperature and distance of moxibustion,and ensured the safety and efficacy of treatment.

OBJECTIVETo compare the efficacy and toxicity of the chemotherapeutic regimen containing pirarubicin and mitoxantrone on the treatment of relapsed or refractory acute myeloid leukemia (AML) in adults.

METHODSIn this open prospective multicentre study, we randomly assigned patients with relapsed or refractory AML to receive TAE regimen (pirarubicin+cytarabine+etoposide) versus MAE regimen (mitoxantrone + cytarabine + etoposide). The efficacy and toxicity were compared between the two groups.

RESULTS56 patients entered this clinical trial. The complete remission (CR) rate on TAE arm was 79.0% versus 55.6% on MAE arm with the overall response (OR) rates of 86.8% versus 88.9%, respectively. The CR was higher on TAE arm (P=0.035) but with no significant difference between the two groups regarding the overall response (OR) rate. The regimens were well tolerated in both groups. Hematologic and non-hematologic toxicity were similar except relatively lower the mean dosage of G-CSF, red blood cells and platelets transfusion on TAE arm. No significant differences were seen between the two groups regarding the overall survival and relapse free survival rates.

CONCLUSIONTAE regimen might be an effective salvage therapy in patients with relapsed or refractory AML.

With widespread popularization, the radiological diagnosis and treatment technology has played an increasingly important role in clinical practice. The tertiary general hospital is generally featured as multiple types of radioisotope and radiation equipment, wide involvement of departments and persons, and many ways of use and potential harms of the radiological diagnosis and treatment technology. Radiation protection has become a content that cannot be ignored in hospital management. This article analyzes the radiation protection management structure of the tertiary general hospital - Guangdong Provincial People’s Hospital. The hospital radiation protection management is gradually improved by clarifying the main leading department, refining duties and responsibilities, strengthening multi-departmental communication and cooperation, and sorting out key connection links. A closed loop of refined management is formed through digging and correcting problems and continuously improving the management level and work efficiency. Valid qualifications are ensured to be obtained in time by radiation workers, radioactive drugs, equipment, and the venues to guarantee the radiation safety of radiation workers and patients and to further promote the construction of the Safe Hospital.
