The reform of payment based on disease diagnosis related grouping (DRG) is an important measure to deepen the medical security system. Its implementation will have a profound impact on the operation and management of public TCM hospitals from four aspects: medical service efficiency, cost, quality, and medical resource allocation. At the same time, there are also difficulties in reform, such as the contradiction between personalized diagnosis and treatment in TCM and standardized payment in DRG 2.0, compatibility issues between TCM medical record data and DRG 2.0 grouping system, limitations of special case negotiation mechanism, and difficulty in cost control and accounting. In response, this study formulated targeted strategies and recommendations intended to facilitate the effective implementation of the DRG 2.0 payment system, and bolster the operational and administrative efficacy of public TCM hospitals, culminating in a favorable scenario of tripartite synergy among "healthcare providers, insurers, and patients".

Objective:To investigate the dosimetric differences between non-coplanar volumetric modulated arc therapy (VMAT) and non-coplanar fixed-field intensity-modulated radiotherapy (IMRT) of Monaco treatment planning system (TPS) in hippocampus-avoidance whole-brain radiation therapy with simultaneous integrated boost(HA-WBRT+SIB) for brain metastases,so as to provide a practical and feasible treatment plan for clinical work. Methods:A total of 22 patients with brain metastases were retrospectively selected. Two radiotherapy plans,which included non-coplanar VMAT and non-coplanar fixed field IMRT of HA-WBRT+SIB,were designed for each patient. The dose distribution,the machine units (MU) of plan,and verification of pre-treatment plan in target area and organs at risk (OARs) between two plans were compared under meeting the prescribed dose requirements of target volume. Results:There were no significant differences in covered volumes (V50 and V55) of 50 and 55 Gy dose,maximum dose (Dmax),heterogeneity index(HI) and conformity index(CI) of planning gross tumor volume(PGTV) between the two plans (P>0.05). For whole-brain planning target volume (PTV-brain-SIB),there was no significant difference in the dose that was covered by 98% volume (D98%) between IMRT and VMAT (P<0.05). VMAT plan could significantly improve the covered volume of 30 Gy dose (V30) of PTV-brain-SIB,and decrease HI value and increase CI value,and the differences of them between VMAT and IMRT were significant (t=-6.366,3.289,-8.343,P<0.05),respectively. The Dmax values of left and right eyes of VMAT plan were significantly lower than those of IMRT plan,and the differences were significant (t=5.784,5.351,P<0.05),respectively. The Dmax value of right inner ear of VMAT plan was higher than that of IMRT plan,and the difference was significant (t=-2.848,P<0.05). VMAT could significantly increase D100% value of left and right hippocampus,which was higher than that of IMRT plan,and the differences of them between two plans were significant (t=-2.564,-6.578,P<0.05),respectively. The MU of IMRT plan was significantly lower than that of VMAT plan,and the difference was significant (t=-6.249,P<0.05). The treatment time of VMAT plan was (294.1±16.4) s,which was significantly less than that of IMRT plan,and the difference of that between two plans was significant (t=-7.400,P<0.001). Under the standards of 3%/2 mm and 2%/2 mm of γ analysis,the γ pass rates of IMRT plan were respectively (99.1±0.6)% and (97.6%±1.0)%,which were significantly higher than those of VMAT plan,and the differences of them were significant (t=-2.733,t=-5.780,P<0.001),respectively. Conclusion:The non-coplanar VMAT and non-coplanar fixed field IMRT based on the Monaco TPS can produce clinically acceptable results for HA-WBRT+SIB in patients with brain metastases. Compared with IMRT,VMAT has better advantage in dose distribution of target volume,and higher treatment efficiency,but IMRT can better protect the hippocampus and reduce the number of MU.

Objective:To investigate clinical efficacy of conformal sphincter preservation operation (CSPO) versus intersphincteric resection (ISR) in the treatment of low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 183 patients with low rectal cancer who were admitted to two medical centers (117 in the Changhai Hospital of Naval Medical University and 66 in the Huashan Hospital of Fudan University) from August 2011 to April 2020 were collected. There were 110 males and 73 females, aged (57±11)years. Of 183 patients, 117 cases undergoing CSPO were allocated into CSPO group, and 66 cases undergoing ISR were allocated into ISR group, respectively. Observation indicators: (1) surgical situations of patients with low rectal cancer in the two groups; (2) postoperative complications of patients with low rectal cancer in the two groups; (3) follow-up; (4) influencing factors for prognosis of patients with low rectal cancer; (5) influencing factors for satisfaction with the anal function of patients with low rectal cancer. Follow-up was conducted using outpatient examination, questionnaire and telephone interview to determine local recurrence, distal metastasis, survival, stomal closure, satisfaction with the anal function of patients. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test.The Kaplan-Meier method was used to draw survival curves, and life table method was used to calculate survival rates. Log-rank test was used for survival analysis. Univariate analysis was performed using the linear regression. Variables with P<0.10 in the univariate linear regression analysis were included for multivariate analysis. Multivariate analysis was performed using the COX stepwise regression model and linear regression analysis. Results:(1) Surgical situations of patients with low rectal cancer in the two groups: cases with laparoscopic surgery, operation time, volume of intraoperative blood loss, distance from tumor to distal margin, cases with postoperative chemotherapy, duration of postoperative hospital stay were 44, (165±54)minutes, (142±101)mL, (0.6±0.4)cm, 76, (6.6±2.5)days for the CSPO group, respectively, versus 55, (268±101)minutes, (91±85)mL, (1.9±0.6)cm, 9, (7.9±4.7)days for the ISR group, showing significant differences between the two groups ( χ2=35.531, t=8.995, -3.437, -3.088, χ2=44.681, t=2.267, P<0.05). (2) Postoperative complications of patients with low rectal cancer in the two groups: 19 patients in the CSPO group had complications. There were 6 cases with grade Ⅰ complications, 12 cases with grade Ⅱ complications, 1 case with grade Ⅲb complication. Fourteen patients in the ISR group had complications. There were 4 cases with grade Ⅰ complications, 7 cases with grade Ⅱ complications, 1 case with grade Ⅲa complication, 2 cases with grade Ⅲb complications. There was no significant difference in the postoperative complications between the two groups ( χ2=0.706, P>0.05). Patients with complications in the two groups were improved after symptomatic and supportive treatment. There was no perioperative death in the postoperative 30 days of the two groups. (3) Follow-up: 183 patients received follow-up. Patients of the CSPO group and ISR group were followed up for (41±27)months and (37±19)months, respectively, showing no significant difference between the two groups ( t=-1.104, P>0.05). There were 2 cases with local recurrence and 9 cases with distal metastasis of the CSPO group, respectively, versus 3 cases and 4 cases of the ISR group, showing no significant difference between the two groups ( χ2=1.277, 0.170, P>0.05). The 3-year disease-free survival rate and 3-year total survival rate were 84.0% and 99.0% for the CSPO group, versus 88.6% and 92.8% for the ISR group, showing no significant difference between the two groups ( χ2=0.218, 0.002, P>0.05). The stomal closure rate was 92.16%(94/102) and 96.97%(64/66) for 102 patients of CSPO group and 66 patients of ISR group up to postoperative 12 months,respectively, showing no significant difference between the two groups ( χ2=1.658, P>0.05). Of the 8 cases without stomal closure in the CSPO group, 2 cases refused due to advanced age, 4 cases subjectively refused, and 2 cases were irreducible due to scar caused by radiotherapy. Two cases in the ISR group had no stomal closure including 1 case of postoperative liver metastasis and 1 case of subjective refusal. There were 92 and 61 patients followed up to 12 months after stomal closure, of which 75 cases and 38 cases completed questionnaires of satisfaction with the anal function. The satisfaction score with the anal function was 6.8±2.8 and 5.4±3.0 for CSPO group and ISR group, respectively, showing a significant difference between the two groups ( t=-2.542, P<0.05). Fifty-four cases in the CSPO group and 21 cases in the ISR group had satisfaction score with the anal function >5, showing no significant difference between the two groups ( χ2=3.165, P>0.05). (4) Influencing factors for prognosis of patients with low rectal cancer: results of COX stepwise regression analysis showed that gender and pT staging were independent influencing factors for disease-free survival rate of patients with low rectal cancer ( hazard ratio=2.883, 1.963, 95% confidence interval as 1.090 to 7.622, 1.129 to 3.413, P<0.05). Gender and pT staging were independent influencing factors for total survival rate of patients with low rectal cancer ( hazard ratio=10.963,3.187, 95% confidence interval as 1.292 to 93.063, 1.240 to 8.188, P<0.05). (5) Influencing factors for satisfaction with the anal function of patients with low rectal cancer: results of univariate analysis showed that surgical method and tumor differentiation degree were related factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.464, -1.580, 95% confidence interval as 0.323 to 2.605, -2.950 to -0.209, P<0.05). Results of multivariate analysis showed that surgical method, tumor differentiation degree and preoperative radiotherapy were independent influencing factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.637, -1.456, -1.668, 95% confidence interval as 0.485 to 2.788, -2.796 to -0.116, -2.888 to -0.447, P<0.05). Conclusion:Compared with ISR, CSPO can safely preserve the anus in the treatment of low rectal cancer, without increasing the incidence of postoperative complications, which can also guarantee the oncological safety and improve the postoperative anal function.

China Pharmacy 2019;30(10):1297-1301
OBJECTIVE: To provide reference for the construction of medicine terminologysets in China.METHODS: By introducing and comparing naming rules, terminology type and classfication system of RxNorm, WHODrug and SNOMED CT, the relevant suggestions on the construction of medicine terminology sets in China were put forward. RESULTS & CONCLUSIONS: Due to the different demanding objects and specific application scenarios of different terminology sets, the three medicines terminology sets had their own characteristics.RxNorm mainly served electronic health records and medical insurance, and its medicine terminology contained the trade name information of the medicine. WHODrug mainly served ADR reports, and its structured medicine information data carried by the Drug Code, and the set adopted the system classification system-ATC. In order to promote the international interoperability of medicines concepts, SNOMED CT did not contained the trade name,and the purpose of classification was to define drugs. It is suggested that the construction of China’s medicine terminology sets should be based on the design and practical experience of foreign advanced drug terminology, encourage hospitals or pharmaceutical companies to disclose and share data, and try to build a drug model compatible with chemical drugs and proprietary Chinese medicines to adapt to the special nature of Chinese medicines and the needs of international communication.

Objective To compare the biomechanical characteristics of medial and lateral locking plates for Schatzker typeⅥfractures of tibial plateau by finite element analysis. Methods A 38 year-old male volunteer was enrolled for CT scan of his lower limbs. His CT images of the left tibial plateau were used for 3D reconstruction of a model of Schatzker type Ⅵ fracture by NX 9.0 software. After the boundary con-ditions were set, a 500 N load was applied to the tibial plateau to simulate the stress on a single leg when an adult weighing 60 kg walked. The displacement and stress on plate and screws were analyzed by Abaqus software. Results The ultimate stress on the model fixated with a medial locking plate was 81.7 MPa, located at the proximal tibiofibular joint surface. The ultimate stress on the model fixated with a lateral locking plate was 487.4 MPa, located at the junction of plate and screws. The ultimate stress on the fibula was much larger in the model fixated with a medial locking plate than in the model fixated with a lateral locking plate. The ultimate displacement was smaller and more homogeneous in the model fixated with a medial locking plate (1.15 mm) than in the model fixated with a lateral locking plate (3.44 mm).Conclusion The Schatzker type Ⅵ fractures of tibial plateau should be fixated with a medial locking plate because it has more biomechanical advantages than a lateral locking plate.
