Technical standards were supports that not only for any profession’s development, but also for the basic means of modern quality control.Forensic clinical medicine has developed nearly 40 years in china, there are 23 normative technical documents at present, the range of its application has been expanding with time, the caseload has been more than 1 million pieces per year all the country. Reviewing these standards, it can be seen: Technital standard of forensic clinical medicine has absorbed a large number of advanced international ideas, assimilating plenty of practice experience at the same time, standard's system has been initially formed, it has become one of the important means to guarantee the quality of medicolegal expertise. Certainly, the construction of forensic clinical standardization in China is still an arduous task, there are also many outstanding contradiction in the existing standards, our studies on international standards were not in-depth, and so on. In the future, forensic science experts still need to strengthen the companion study of technical standards and laws or regulations, intensify tracing and evaluating of international standards in order to form more adaptive and advanced technical standards.

Objective To study the expression of inducible nitric oxide synthase (iNOS),endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF) in human gastric cancer and their relationship with tumor angiogenesis and to investigate the interaction of NOS and VEGF in gastric cancer.Methods The expression and distribution of VEGF, iNOS and eNOS in 34 gastric cancer specimens were detected with immunohistochemistry. Microvessel density (MVD) was counted with FⅧRAg immune specific staining.Results The expression rates of iNOS, eNOS and VEGF in 34 gastric cancers were 73.5%, 82.4%and 91.2%respectively. The expression of VEGF had a significant positive relation with iNOS, but not with eNOS. The MVDs of VEGF or iNOS positive gastric cancers were obviously higher than those of VEGF or iNOS negative gastric cancers. There was no significant difference between the MVDs of eNOS positive gastric cancers and eNOS negative ones. Conclusion MVD increases with increase of expression of VEGF and iNOS in gastric cancer. It is indicated that VEGF and iNOS can promote gastric cancer angiogenesis. VEGF and iNOS have a significant positive correlation, which suggests that in human gastric cancer, iNOS plays an important role in the production and action of VEGF.

The theory of cancer stem cells proposed that recurrence and metastasis of liver cancer are closely related to liver cancer stem cells.The traditional surgical treatment of liver cancer simply kills those rapidly proliferating tunor cells instead of eliminating hepatic cancer stem cells which play decisive role in recurrence and metastasis.As far as people have concerned,there are many signaling pathways and regulatory factors modulating liver cancer stem cells,such as the Wnt/β-catenin pathway,TGF-β pathway,Notch pathway,Hedgehog pathway,hepatitis B virus,as well as epigenetics.Further studies on regulatory mechanisms of liver cancer stem cells are of great significance,in hope of providing new evidence for treatment and prevention of recurrence and metastasis of liver cancer.

0.05). The levels of progesterone and hCG in the inevitable group were significantly decreased to(36?17) nmol/L and(13 ?3) kU/L, respectively. The differences when compared to the other groups were statistically significant (P0.05). Conclusion LIF may play a role in the maintenance of normal pregnancy. Reduction of LIF expression in chorionic villi may induce the decrease of serum progesterone and hCG levels and, ultimately, cause inevitable abortion.

The endoluminal stenting is popular for more than two decades,even in China,encouraging achievements also are getting around the recent dacade.Endoluminal stents are not only applicated for all kinds of vascular stenosis,and nonvascular stenosis such as biliary tract,esophagus,trachea etc,but also are utilized gradually in the interventional treatment of cerebral ischemia and hemorrage in the recent years,especially for aortic aneurysm.There would still have a long way to go in China for further development in basic research,standardized procedure,and normalized followed-up.The main target for all the interventional radiologists in the foreseen future is how to develop new stents with independent knowlege property right and to expand the stents usage reasonably.

AIM: To establish the fingerprint analysis of Yadanzi Youru Injection(Fructus Bruceae) and to provide the quality information by capillary gas chromatography(CGC). METHODS: The CGC method was used.The capillary column was Supelcowax~(TM)-10(30 m?250 ?m?0.25 ?m),The detector was FID. RESULTS: The result showed that 4 peaks were common and the content of oleic acid in Yadanzi Youru Injection was determined.The linear ranges were within(0.34)～(2.07) ?g/L,r=0.999 9 n=5; CONCLUSION: The method is simple,accurate and reproducible.It can be applied to the quality control of Yadanzi Your Injection.

Objective To research the survivability of pinaverium bromide in elderly colonoscopy preoperative preparation to improve the quality of the elderly colonoscopy.Methods Three hundred elderly outpatient who underwent colonoscopy were enrolled in this study and were randomly divided into observation group and control group,with 150 patients in each group.The patients in observation group were given pinaverium bromide100 mg,3 times a day with the meal,and at the last time they took 100 mg before 2 h of colonoscopy.The patients in control group took nothing.The entry time and abdominal pain class were recorded by endoscopic doctors and assistants and compared between two groups.Results The completion rate of observation group and control group was 98.0％(147/150)and 93.3％(140/150),the successful rate of observation group and control group was 78.0％(117/150) and 65.3％(98/150),and there were significant differences (x2 =3.94,5.93,P ＜ 0.05).The number of entry time ＜ 5 min,5-10 min,＞ 10 min in observation group was 25,60,62 cases,in control group was 10,53,77 cases,and there was significant difference (P ＜ 0.05).The abdominal pain class Ⅰ,Ⅱ,Ⅲ,Ⅳin observation group was 32,85,30,3 cases,in control group was 21,77,42,10 cases,and there was significant difference (P ＜ 0.05).There was no adverse reaction in observation group.Conclusions Taking pinaverium bromide before colonoscopy 1 d in elderly patients can help to alleviate the symptoms of conventional colonoscopy abdominal pain and increase the tolerance of elderly.

Objective To explore effect of treatment of a non-surgical spinal decompression system(SDS) on neck muscle surface electromyography(EMG)of patients with cervical spondylotic radiculopathy(CSR).Methods Sixty patients with CSR in Department of Rehabilitation Medicine at The First Affiliated Hospital of Sun Yat-sen University in China between February 2014 and February 2016 were recruited and randomly divided into SDS group and control group,with 30 patients for each group.The SDS group and control group were treated with the SDS and general traction system for cervical traction respectively.Surface EMG telemeter was used to measure the surface EMG signals of the affected side cervical erector spinae muscle and sternocleidomastoid with the score of averaged EMG value(AEMG)and the median frequency(MF)as surface electromyogram signal evaluation indexes,and VAS and NDI as therapeutic effect evaluation indexes after a course of treatment.The data before and after the treatment were statistiacaly analyzed.Results During the first traction with tradtional traction or SDS,AEMG values of the cervical paraspinal muscle and sternocleidomastoi were significantly decreased and MF values significantly increased as compared with those before the traction (all P＜0.05).After a course of treatment,AEMG values of affected side cervical erector spinae muscle and sternocleidomastoi of SDS group were significantly decreased as compared with those before the treatment,and they were significantly lower in SDS group than in ordinary group (all P＜0.05);and MF values of affected side cervical erector spinae muscle and sternocleidomastoi in SDS group were significantly increased as compared with those before the treatment,and they were significantly higher in the SDS group than in the ordinary group (all P＜0.05).VAS and NDI scores of the two groups after a course of treatment were significantly lower than those before the treatment (P＜0.05),and VAS and NDI scores were significantly lower in the SDS group than in the ordinary group (P＜0.05).Conclusion SDS traction is superior to ordinary traction in relieving pain,improving function,relaxing neck muscles and alleviating muscle fatigue.
