Objective To investigate the surgical treatment and perioperative care of the elderly patients with colorectal cracinoma.Methods The surgical treatment of 77 elder patients above 70 with colorectal carcinoma was analyzed.Results 54 patients were resected curatively,tumor resection rate 70%,12 patients were resected palliatively,9 cases in cecostomy,2 cases in by-pass operation.26 instances of postoperative complications happened.5 in death,with 6% mortality rate.Conclusion Allround preoperative preparation,strengthy perioperative care and correct operation procedure is a safety and effective way to raise tumor resection rate and reduce preexisting diseases for the elderly patients with colorectal carcinoma.

BACKGROUND: Theoretically, a novel single-sided groove target release biodegradable stent can avoid drug-induced inflammation of the local vessel wall, reduce drug dose, decrease the likelihood of thrombosis, and relieve stenosis.OBJECTIVE: To evaluate the influence of the novel single-sided groove target release biodegradable stent on intimal hyperplasia in a healthy porcine coronary artery model.METHODS: Eighteen healthy pigs were randomly divided into three groups, bare metal stent group, Firebird metal stent group and Firehawk stent group, which were implanted with L605 cobalt chromium alloy bare metal stents and L605 cobalt chromium alloy non-biodegradable rapamycin-eluting stent and L605 cobalt chromium alloy biodegradable rapamycin-eluting stent, respectively. Two same stents were implanted into the left anterior descending artery and the right coronary artery of each pig, respectively. After 1 and 3 months of follow-up, coronary angiography was performed,and the pigs were killed to take coronary artery samples for detection of intima hyperplasia.RESULTS AND CONCLUSION: At 1 and 3 months after stent implantation, no stenosis, thrombosis and aneurysm occurred in the three groups shown by the coronary angiography; the lumen loss was significantly lower in the Firebird metal stent group and Firehawk stent group than the bare metal stent group (P < 0.05), while there was no difference between the Firebird metal stent group and Firehawk stent group. Histopatologically, there was no coronary arterial tissue necrosis or luminal thrombosis in the three groups. Compared with the bare metal stent group, at 1 and 3 months after stent implantation, the neointimal area and the percentage of stenosis were significantly lower in the Firebird metal stent group and Firehawk stent group (P < 0.05), while the residual lumen area and internal elastic lamina area were significantly higher (P < 0.05). Additionally, there was no significant difference between the Firebird metal stent group and Firehawk stent group. Overall, the Firehawk stent that achieves the same clinical efficacy as the non-biodegradable rapamycin-eluting stent effectively inhibits intimal hyperplasia, and prevents stent restenosis after stent implantation.However, future investigations on the long-term effect are warranted.

Shanghanlun contains the theory of stagnation,though which is concealed among the treating system.This theory is great important to clinical practice.When we have a whole understanding to the theory of stagnation,it is easy to analyze the obstruction-removing therapy.Though this principle hasn't clearly definition,it is connected closely with other regular treating methods.Based on it,the dissertation analyzes all kinds of obstruction-removing therapy in Shanghanlun.That will be very helpful for readers to understand this theory and its significance in clinical practice.

Objective To discuss the safety and efficacy of laparoscopic modified ventrifixation for women with uterine prolapse.Methods Thirty-seven women with Ⅱ-Ⅳ degree uterine prolapse were undergent laparoscopic modified ventrifixation in the the First Hospital of Qinhuangdao and Anzhen Hospital of Beijing from January 2008 to June 2012.The midpart of a noabsorble PROLENE soft mesh was sutured to the anterior cervical fascia.Two back ends of the mesh were passed through extraperitoneal channels through ligamentum latum uteri and sutured to the abdorminal wall to fix uterus.The effect and complications were observed.Results The objective and subjective success rate were 100％ and 91.9％ respcetively at 6 months after operation.All patients were followed up for 6 to 48 months.Prolapse recurrence rate was 10.8％ (4/37).Conclusion Laparoscopic modified ventrifixation is effective,safe and mini-invasive in the treatment of uterine prolapse.The surgery may be a satisfactory procedure for women with uterine prolapse hoping for uterine preservation.

To control the quality of Yixue caps ule,its main comp onents were identified by TLC and the content of tanshinone ⅡA was determined b y TLC scanner.A good linearity was shown at the concentration of 0.5 to 2. 5 μg of tanshinone ⅡA.The average recovery rate was 97.90% and RSD was 1.16%.This method is specific and sensitive with good reproducibility and can be used for the quality control of the preparation.

In most universities the usage of digital information resources are not ideal.One reason is that primary audience groups of libraries——college students rarely use these resources.So we propose some measures and proposals for university libraries to provide the service of digital information resources for university students.

Objective To establish a method for the content determination of 3-epibetulinic acid in Nodus Nelumbinis Rhizomatis Charcoal. Methods HPLC was used on Lichrospher C18 column (4.6 mm?150 mm, 5 ?m) with mobile phase of acetonitrile-0.2% glacial acetic acid (75∶25), the flow rate of 1 mL/min, the column temperature of 30 ℃ and the detection wavelength of 207 nm. Results 3-epibetulinic acid has a good linearity within 0.365 4～3.654 0 ?g (r=0.999 6) and the average recovery was 98.83% with RSD=2.47%. The content of 3-epibetulinic acid in Nodus Nelumbinis Rhizomatis Charcoal from different region varied from 0.048 3% to 0.575 8%. Conclusion This method is simple, accurate, with good reproducibility, and can be used for the content determination of 3-epibetulinic acid in Nodus Nelumbinis Rhizomatis Charcoal.

Objective To offer the theoretical evidence for clinical application,we observed the changes of angiographic appearances and local pathological changes before and after embolizing the left gastric artery with mitomycin C gelatin microspheres (MMC-MS).Methods Catheter was delivered into the left gastric arteries via femoral artery and then infused MMC-MS.The angiographic appearances and local pathological changes were observed immediately,and then with follow up of 6～8h,24h,72h,1w,2w and 4w. Results The minute arterioles of tunia mucosa and tela submucosa were mainly embolized inducing edema and focal necrosis.With the degradation of MMC-MS,the damage of gastric tissue was alleviated but turned normal after 4 weeks.The results of DSA showed that no recanalization of the embolized vessels occurred after one week of emboliatdion but revealed one recanalization after two weeks and two in four weeks.Conclusions The damage of tissue induced by embolizing the left gastric artery with MMC-MS can be recovered.The application of the MMC-MS is feasible.
