The incidence of pancreatic carcinoma is increasing obviously in recent years with a serious threat to the people's life, and yet there is not a single treatment for obtaining satisfactory prognosis. At present, the radical resection is the primary method for resectable pancreatic carcinoma, together with radiotherapy can improve the surgical resection rate and reduce the dissemination of tumors. Intraoperative radiotherapy can alleviate the pain and increase the survival rate, but the role of postoperative radiotherapy and chemotherapy is still in controversial. There is a lot of advantages for regional chemotherapy theoretically, but lack of evidence in practice. Physical therapy and biological therapy in the treatment of pancreatic carcinoma have been recognized extensively. It is possible to change fundamentally the current status of treatment and to improve the long-term survival rates with the quality of life until establishing a comprehensive treatment system mainly depended on surgical resection with combination of radiotherapy, chemotherapy, physical and biological treatment. The interventional therapy has been significantly developed as an important palliative treatment during recent years.

In the criminal cases of driving under the influence (DUI), DNA evidence can be collected from the deployed airbag of the motor vehicle and submitted to the crime lab for touch DNA analysis. The evidence can be acquired when the skin cells are observed on the surface of the airbag in a traffic accident. However, the low quantity or quality of the evidence collected from a crime scene prevents further identification analysis in many cases. In the current study, we reported a case of identifying touch DNA extraction from the shed skin cells from the deployed airbag of a motor vehicle. We managed to collect DNA evidence from the shed skin cells in an airbag using a proper approach of collection and extraction. The 5.87 ng of extracted DNA was sufficient for genotyping and forensic identification, which helped to identify the driver of the car in collision with a pier in the street. In DUI cases and other traffic accidents, therefore, the amount of touch DNA extracted from the deployed airbag can be sufficient for DNA marker genotyping and further analysis.

Objective To observe the antibacterial effects of amikacin sulfate combined with the ingredient of coptis chinensis:the extract of coptis chinensis, berberine hydrochloride and palmatine hydrochloride on multiple drug resistance (MDR) of Escherichia coli (E.coli) in vitro. Methods One hundred strains of E.coli checked out from 2013 to 2014 that showed resistence to cefotaxime were selected, and in which MDR to bacteria were determined. The extended-spectrum β-lactamases (ESBLs)-producing by Kirby-Bauer test. The minimum inhibitory concentrations (MIC) of the extract of coptis chinensis, berberine hydrochloride, palmatine hydrochloride and amikacin sulfate on ESBLs-producing E.coli were determined firstly, and then the sterilization effects of amikacin sulfate combined with the other three medicines were observed by broth microdilution checkerboard method together with their fractional inhibitory concentrations (FIC), with ATCC 25922 for quality control strains. Results Ten MDR E.coli were screened and proved to be ESBLs-producing. The inhibitory effects were enhanced in a synergistic or additive pattern when amikacin sulfate combined with the extract of coptis chinensis, berberine hydrochloride on nine of the ten MDR E.coli in vitro, where the inhibitory effects were a synergistic or additive pattern when amikacin sulfate combined with palmatine hydrochloride on all of the MDR E.coli in vitro. Conclusion Palmatine hydrochloride or berberine hydrochloride or the extract of coptis chinensis combined with the amikacin sulfate has significant value in treatment of MDR E.coli, which is worthy of further study.

Objective To compare the influences of off-pump and on-pump coronary artery bypass grafting operation on plasma thyroid hormones.Methods Forty patients undergoing coronary surgery were randomly divided into off-pump group(n=20)and on- pump group(n=20).Plasma thyroid hormones(T_3,T_4,FT_3,FT_4,rT_3)and thyroid-stimulating hormone(TSH)were studied perio- peratively.Results Before operation,the values of aU the variables were within normal range in the two groups.In off-pump group, T_3 and FT_3 concentration dropped significantly after operation,reaching the lowest value at first day postoperatively[T_3:(39.7?6.2) ng/dl vs.(78.6?2.1)ng/dl,P0.05),which were within normal range all along,rT_3 concentration rose significantly after operation,reaching the highest value at third day postoperatively[(82.1?26.8)ng/dl vs.(42.3?15.6)ng/dl, P0.05),whereas baseline,operative and postoperative variables were similar.Con- clusion Off-pump operation has some influences on plasma thyroid hormones,showing"low T_3 syndrome"postoperatively,that is similar to what on-pump operation does.

Objective To explore the role of serum S-100B concentration of umbilical cord blood and blood on the 24 h after admission in the early diagnosis and development of newborn hypoxic-ischemic encephalopathy(HIE).Methods Forty-six HIE newborns(31 cases with mild HIE and 15 cases with moderate and severe HIE)were selected as HIE group,and 43 normal full-term newborns were selected as control group.The umbilical cord blood sample and blood sample were aquired on the 24 h after admission.The serum S-100B concentration was detected by enzyme-linked immunosorbent assay(ELISA)analysis.Results 1.There was no significant difference of serum S-100B concentration between the male sub-group and female sub-group of normal group and their birth weight had no significant relative to the serum S-100B concentration.2.The serum S-100B concentration of umbilical cord blood of control group and HIE group were(1.03?0.32)and(2.53?1.1)?g/L,respectively,there was significant difference between two groups(t'=8.848 P

OBJECTIVES: To analyze the effect of walking pace on the fitness of middle-aged and elderly people in order to provide more theoretical data for the development of entensive mass fitness based on the means of sports physiological and biochemical techniques. METHODS: The selected 80 middle-aged and elderly subjects were divided into three groups:brisk walking group A (=30, 56.26 ±3.68 years), brisk walking group B (=30, 57.65 ±4.78 years), and control group C (=20, 55. 73 ±4. 18 years). Exercise group A:10 000~12 000 steps/day, a total of 16 weeks; walking group B:10 000~12 000 steps/day in the first 10 weeks, 14 000~15 000 steps/day in the last 6 weeks. Control group C:keeping the normal living conditions. The indicators were tested before the experiment and after the tenth week and the sixteenth week of the experiment. Test indicators included systolic blood pressure, diastolic blood pressure, heart rate, vital capacity, timed vital capacity, total cholesterol, triglycerides, high density lipoprotein cholesterol, low density lipoprotein cholesterol. RESULTS: The levels of systolic blood pressure, diastolic blood pressure, total cholesterol and triglyceride were decreased significantly (<0.05, <0.01), while the vital capacity and high density lipoprotein cholesterol were increased significantly in both exercise groups afler 10 and 16 weeks compared with those in the same group betor test(<0. 05, <0. 01). The levels of diastolic blood pressure, timed vital capacity, serum triglyceride and high density lipoprotein cholesterol in exercise group B after 16 weeks were significantly higher than those of exercise group A (<0.05). CONCLUSIONS Ten thousand steps away every day can effectively improve the indexes of blood pressure, vital capacity, serum triglyceride, total cholesterol and high density lipoprotein cholesterol of middle-aged and elderly men and it can further improve the indicator above by increasing the number of steps after 10 weeks.

OBJECTIVE: To explore the relation between the behavior psychology analysis of partial mechanical injuries and the nature of death in high-falling cases, and provide reference, for such cases. METHODS: Of 311 death victims of high-falling injuries collected from 2008 to 2013, 205 cases were associated with partial mechanical injuries. The characteristics of injury formation, preliminary crime scene traces, fatal injury of high-falling, and text messages were all retrospectively analyzed. RESULTS: According to the investigation of preliminary crime scene traces, fatal injury of high-falling and text message, there were 86 suicide, 24 accident and 95 uncertainty in the 205 cases. According to the behavior psychology analysis of partial mechanical injuries, there were 80 suicide, 11 accident, and 4 homicide in the 95 uncertainty cases. CONCLUSION The partial mechanical injuries uncertainly caused by high-falling correlate with the manner of high-falling death. According to the behavior psychology analysis of the partial mechanical injuries in high-falling death cases, the presumption of high-falling death is usually accurate
