Objective To investigate the expression of nm23-H1 in human benign and malignant colorectal lesions and the relationship between invasion,metastasis in colorectal carcinoma.Methods The expression of nm23-H1 were determined by ABC immunohistochemical technique in 80 cases human colorectal carcinoma,and compared with that in adenoma and normal mucus.Result Positivity expression rates of nm23-H1 were 66.7% in colorectal carcinoma.No significant difference of the expression of nm23-H1 in normal mucus,adenoma and cancerous tissue (P>0.05).The positive rates of nm23-H1 expression in different pathological grading,lymph node metastasis and post-operative survival (3 years) were showed significant difference (P<0.05).Conclusions It is suggested that the deletion of nm23-H1 low expression might play an important role in the carcinogenesis,development,metastasis and prognostic value of human colorectal carcinoma.

Objective To probe timely diagnosis and surgical intervention of traumatic diaphragmatic rupture(TDR). Methods The clinical data of 161 patients with TDR treated surgically in our department during the past 17 years were analyzed retrospectively in respects of diagnostic methods,accuracy of preoperative judgment of TDR,incidence of diaphragmatic hernia,surgical procedures and outcome,etc. Results There were 139 males and 22 females at a mean age of 32.4 years(9-84 years),with average ISS of 27.8 points(13-66 points).Of all patients,65.2%had shock at admission.For these 161 patients,36 suffered from blunt injuries and 125 from penetrating injuries.For diaphragmatic injury.preoperative diagnostic rate was 88.9%for blunt injuries and 78.4%for penetrating injuries (P>0.01).The incidence of diaphragmatic hernia was 94.4%in blunt injuries and 14.4%in penetrating injuries(P<0.05).In this series,thoracotomy was performed in 30 patients,laparotomy in 106,thoracotomy plus laparotomy in 18 and combined thoraco-laparotomy in 7,with overall fatality rate of 10.6%and a mean ISS of 41.6 points.The mortality rate was 22.2%in blunt injuries and 7.2%in penetrating injuries(P<0.01).The main causes for death were hemorrhagic shock and septic complications; Conclusions Blunt diaphragmatic injury can be diagnosed by radiographic signs of diaphragmatic hernia.According to"offside sign",which implies a thoracic wound with positive physical or radiological signs in the abdomen or in the thorax,penetrating diaphragmatic injury can be recognized.To deal with diaphragmatic hernia,it is important to judge the vitality of viscera.Penetrating injury has a relatively good prognosis.

Hepatic encephalopathy (HE) has various clinical symptoms, and its etiology and pathogenesis have not been fully understood. Recent studies have shown that the composition of intestinal flora is associated with the changes in the central nervous system in patients with HE. With reference to recent studies in China and foreign countries, this article analyzes and summarizes the regulatory mechanism of intestinal flora on HE through the liver-brain axis from the perspectives of microbiology, nervous system, and immunology, and it is pointed out that in-depth studies on the mechanism of action of intestinal flora are needed for the treatment of HE and can provide a clear basis for clinical diagnosis and treatment.

Objective :
To analyze the status and influencing factors of the intention of people aged 18 to 25 years to primary medical institutions and their satisfaction for health services in Zhejiang Province, so as to provide basis for the improvement of health services in primary medical institutions.
Methods:
During November and December in 2019,the 18-25 year-old people in Zhejiang Province were recruited to investigate the general information, intention to seek medical advice and satisfaction for health services in primary medical institutions through WeChat. Logistic regression was performed to analyze the influencing factors of the intention and the satisfaction. Importance matrix was used to analyze the key drivers of the satisfaction.
Results:
Among the 620 people surveyed, with a response rate of 93.37%, 142 (22.90%) chose primary medical institutions for advice. Actually 516 (83.23%) people went to primary medical institutions last year, and 384 ( 74.42% ) of them were satisfied with the health services. The results of multivariate logistic regression analysis showed that the people aged 18-25 years who were under the new rural cooperative medical care system ( OR=3.062, 95%CI: 1.745-5.373 ) and who had records in community health centers ( OR=0.547, 95%CI: 0.308-0.970 ) were more likely to go to primary medical institutions for medical advice; the ability of doctors ( OR=1.478, 95%CI:1.168-1.871 ) ,the drug notification by medical staff ( OR=1.308, 95%CI: 1.065-1.606 ) , routine examination items ( OR=1.523, 95%CI: 1.227-1.889 ) , the ways of payment ( OR=1.168, 95%CI: 1.017-1.340 ) , the comfort of environment ( OR=1.785, 95%CI: 1.437-2.219 ) and the bulletin boards of health knowledge ( OR=1.302, 95%CI: 1.086-1.561 ) were associated with the satisfaction. The results of importance matrix analysis showed that the ability of doctors and routine examination items were the priorities to improve, followed by the drug notification by medical staff; the comfort of environment had competitive advantages; the ways of payment and the bulletin boards of health knowledge needed to be further analyzed.
Conclusions
The 18-25-year-old people in Zhejiang Province were less intended to seek medical advice in primary medical institutions, which was associated with the type of medical insurance and records in community health centers. They were satisfied with the health services, the ability of doctors and routine examination items were the key drivers.

The incidence of thyroid cancer has continued to increase. Most thyroid cancer patients have good prognosis, but there are still some patients who will develop into the middle or late stage. The status of cytotoxic treatment in thyroid cancer treatment is controversial. Chemotherapy, as a classical malignant tumor treatment, has its unique significance for the special type and the special period of thyroid cancer. Chemotherapy can be an option for systemic treatment if no other treatment is available for patients of differentiated thyroid carcinoma refractory to radiodine in rapid progression and life-threatening period. For patients of anaplastic thyroid cancer in progression period, chemotherapy can be selected if there are no other treatments in clinical trials. And "Chemical therapy plus" treatment model might play an important role in thyroid treatment, because with the development of targeted drugs and immunotherapy, chemotherapy combined with other treatments can reduce the dosage of chemotherapy drugs to reduce the toxic side effect, and can improve other therapeutic effects.
