Field operations,work and war on plateau is an important part of future war. It is necessary to study the early treatment and evacuation of scull injury. Research and survey were made in 7 field hospitals and hundreds of records were summaried before treatment criterion in early phase was put forward for patients on plateau as well as the evacuation in different level and stage,which aims to actively save patients' lives within limited time and reduce the death rate and prevent deformity. References are provided for war,training,and construction in battlefield.

[Abstact] Objective To investigate the efficacy and safety of sunitinib as first line therapy in treating those patients with metastatic renal cell carcinoma ( mRCC ) .Methods A total of 66 patients , including 42 male and 24 female cases ,with metastatic renal cell carcinoma were enrolled from January 2009 to June 2014.The median age was 52 years (range 26-75 years).According to American Joint Committee On Cancer (AJCC) staging,there were 35 cases of T3 stage,31 cases of T4 stage.All patients had distant metastasis ,including single organ metastasis in 52 patients and multiple organ metastasis in 14 cases.Sixty-one patients received prior radical nephrectomy ,5 patients received biopsy .Sixty-two patients were diagnosed as renal clear cell carcinoma and 4 patients were diagnosed as renal papillary cell carcinoma .Sunitinib was administered in standard 4/2 regimens.Briefly, patient takes 50 mg once a day orally for 4 weeks.Then the sunitinib will be stopped for 2 weeks.Six weeks was defined as 1 cycle.It should be continued until disease progression or occurrence of intolerable adverse reactions .The efficacy of sunitinib should be evaluated within 2 cycles.Results The duration of following-up ranged from 5 to 66 months.The efficacy could be evaluated in 63 patients.Two patients ( 3.2%) achieved complete remission .Twelve patients ( 19.0%) achieved partial remission.Forty-five patients (71.4%) demonstrated stable disease and 4 patients (6.3%)
developed progressive disease .The disease control rate was 93.7%(59/63) and the objective response rate was 22.2%(14/63).2 (3.2%) patients died due to the progression of disease .The most commonⅠ-Ⅱadverse events included fatigue in 36 cases ( 57.1%) , thrombocytopenia in 36 cases ( 57.1%) , hand-foot syndrome in 32 cases (50.8%),hypertension in 27 cases (42.9%),neutropenia in 15 cases (23.8%), hypothyroidism in 12 cases (19.0%), diarrhea in 6 cases (9.5%) and alopecia in 4 cases (6.3%).Ⅲ-Ⅳ adverse events were hand-foot syndrome in 4 cases ( 6.3%) , hypertension in 2 cases ( 3.2%) , neutropenia in 5 cases (7.9%) and thrombocytopenia in 5 cases (7.9%).Most mild adverse reactions after symptomatic treatment could be alleviated ,did not affect the medication .When the adverse events returned to the Ⅰ-Ⅱdegree, the 37.5 mg sunitinib was resumed once daily by orally.NoⅢ-Ⅳadverse events were reported again.Conclusions Sunitinib was efficacious in the treatment of advanced renal cell carcinoma.Most mild adverse events were tolerable ,and severe adverse events need medical treatment .

Objective To discuss the dosimetric differences in the planning methods between physical and biological optimization during thehypofractionated radiotherapy for lung cancer.MethodsTen cases of non-small cell lung cancer (NSCLC) receiving radiotherapy were selected in this retrospective study.The VMAT plans for all patients were re-designed by physical functions (DV group),biological combined with physical functions (DV+EUD group and EUD+DV group) and biological functions (EUD group).The constrained functions were different,whereas the constrained conditions and optimized parameters were identical among four groups.The dosimetric differences among four optimization methods during thehypofractionated radiotherapy for lung cancer were evaluated through calculating and analyzing each dosimetry parameter.Results For the target area,the equivalent uniform dose was approximate between the EUD and EUD+DV groups.The EUD in these two groups was approximately 2.8％-3.6％ and 3.2％-3.7％ higher than those in the DV and DV+EUD groups.The average tumor control probability (TCP) in the EUD and EUD +DV groupswas considerably higher than those in the other two groups (both P＜0.05).The homogeneity index (HI) significantly differed (all P＜0.05),whereas the conformity index (CI) did not differ (all P＞0.05).For the organ at risk (OAR) area,the differences of EUD,V5,V1o,V20,V30 of normal lung tissues and the difference of dosimetry parameters in heart and spinal cord were not statistically significant (all P＞0.05).The mean dose of all lungs in the EUD and EUD+DV groupswas slightly lower than those in the other two groups.ConclusionsBiological optimization method has certain advantages in increasing EUD and TCP in the target area and decreasing the irradiation dose of normal lung tissues,which provides references for selecting the optimization method with biological functions in clinical practice.

Objective: In order to understand the current situation and influencing factors of teaching quality in a Medical University in Yunnan, thus improving the teaching quality of the teachers. Methods: The self-made evaluation forms for teachers' teaching quality which include 9 first-level indicators were adopted. In December 2016, a survey was conducted on some students from grade 2013 to 2016 about the teachers who gave them lectures from September to December 2016, involving 7 different majors, 23 teachers and 18 courses. SPSS 21.0 was used for data analysis. Enumeration data were described by frequencies and percentages. Univariate and multivariate Logistic regression analyses were used for satisfaction. Results: There were 1 542 valid questionnaires collected in this survey. Univariate Logistic regression analysis showed that there were 6 factors related to the overall satisfaction of teachers' classroom teaching quality, which were "whether the courses are professional (OR=1.430)", "curriculum difficulty (OR=1.731)", "curriculum progression (OR=1.620)", "learning time after class (OR=1.141)", "interest before class (OR=1.565)", and "interest after class (OR=2.291)", respectively. Conclusion "courses are professional", "courses are too easy", and "the progression of courses is slow " are favorable factors for high satisfaction degree, while "courses are set up by the departments that the students belong", "learning time used after class is too short", and "interest for study is decreased after class" may be unfavorable factors for high satisfaction degree.

OBJECTIVE To establish an HPLC method for determination of the related substances in papaverine hydrochloride. METHODS NanoChrom ChromCore 120 C8 column was used; the mobile phase A consisted of 3.4 g·L−1 potassium dihydrogen phosphate aqueous solution, adjust pH to 3.5 with phosphoric acid-acetonitrile(90∶10), the mobile phase B was methanol, with gradient elution at the flow rate of 0.8 mL·min−1; the detection wavelength was 238 nm; the column temperature was 50 ℃. RESULTS The minimum separation between the main component and each impurity was >1.5; Papaverine and its thirteen impurities showed a good linear relationship in the self-concentration range(r>0.999); and the average recoveries were 93.1%−101.2% with RSDs of 2.3%−8.1%. CONCLUSION The method is accurate, sensitive and reliable, which is suitable for the determination of related substances in papaverine hydrochloride.
