Soft tissue tumors have specific morphologies. In many cases, differential diagnoses pose a challenge, and as such, immuno-histochemical and molecular methods are often needed. With the development of molecular genetics, the discovery of new diagnostic antibodies and genetic targets, and the emergence of further applications to clinical practice, clinically individualized and precision treatments have also been widely used. In the future, however, we must further investigate the molecular mechanisms of soft tissue tumors to improve their diagnosis and treatment.

Objective To investigate the physical fitness status of stationed on an island and the influence factors of military operational ability in order to take effective intervention measures to cope with the problems encountered by the garrison force.Methods The outdoor environment heat intensity of the island was monitored and evaluated by thermal environment monitors.The physical fitness of thirty-eight soldiers randomly selected was evaluated by measuring VO 2max. Ninety soldiers stationed on this island were selected by random sampling , for whom questionnaires and interviews were designed, involving the influence factors of military operational ability .Results This island was a typical humid-hot environment, with high temperature , high humidity and high radiation .The physical fitness of soldiers declined obviously because of the typical humid-hot environment.The top five working environmental factors were high temperature , humidity, solar radiation, wind and seasonal drying .The top five personal factors were physical fatigue , overtraining, injury, mental fatigue and lack of sleep .Conclusion Considering the obviously decreased physical fitness of soldiers caused by the typical humid-hot environment , how to assess military combat effectiveness and how to determine whether the level of combat effectiveness can meet the actual needs of tropical combat , requires scientific indicators and criteria of evaluation .

Objective To investigate the morbidity of soldiers stationed on an island ,analyze the relationship betweendiseases and the environment,and to provide an effective method for disease prevention and treatment .Method Data ofoutpatients from troops stationed on an island between September 2012 and August 2013 were statistically investigatedaccording to the classification of diseases.The cause of disease was analyzed .In addition,90 soldiers stationed on an islandwere randomly selected to investigate their response to heat and humidity and parts susceptible to skin diseases viaquestionnaires and talks.Results A total of 789 cases of disease were identified,including 226 cases of upper respiratorytract infection,118 cases of orthopedic-related diseases,90 cases of traumatic diseases,88 cases of oral diseases,74 casesof digestive system diseases,62 cases of skin diseases,53 cases of ENT diseases,41 cases of urinary tract infection,and37 cases of anorectal diseases.The top five responses to heat and humidity were sweating,thirst,body fatigue,dizzinessand profuse sweating.The most susceptible part to skin diseases was the feet ,followed by the cheek,crotch,back andneck.Conclusion The epidemiological characteristics of diseases on this island are significant,and medical supportshould be focused on improving the overall level of hospital treatment.

Preoperative neoadjuvant therapy of rectal cancer has been widely promoted, and postoperative standardized pathological assessment has gradually attracted widespread attention. Accurate pathological examination plays an indicating role in the diagnosis and treatment of rectal cancer, which can not only evaluate the effects of neoadjuvant chemoradiation and surgical resection, but also guide postoperative adjuvant therapy and assess the prognosis. Tumor regression grade (TRG) and TNM staging are the bases of routine pathological diagnosis of rectal cancer, and they are closely related to patient survival and prognosis. At present, TRG evaluation methods for neoadjuvant chemoradiation include NCCN, AJCC, Becke, Mandard, Dowrak/Rodel, MSKCC, and RCRG. However, there is still no universally accepted best standard. The commonly used classifications in practice are AJCC and NCCN TRG grading standards. The prerequisite for accurate TRG classification is a detailed and standardized pathological assessment, which includes both gross assessment of the specimen and microscopic examination. How to evaluate the therapeutic response to lymph node metastasis after neoadjuvant therapy and improve the assessment consistency among pathologists are the two major issues that remain to be resolved.
