The drugs such as sildenafil adulterated in herbal products and dietary supplements may endanger human health. The number of the new modified derivatives is increasing recently. Based on Q-TOF-MS, a new sildenafil analogue was found. It was isolated and purified by preparative liquid chromatography. Its structure was determined by NMR, as 1-[4-propoxy-3-(6, 7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d] pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Compared with sildenafil, the ethoxy group of the benzene ring moiety was moved to the propoxy group, which had not been reported in China. The mass spectrometric behavior pattern of the structure type was summarized, which can greatly accelerate the structural analysis of novel analogues.

Objective To observe the specific changes of content of cyclic guanosine monophosphate (cGMP) around meridian skin and specific influences of electroacupunture Neiguan (PC6) on cGMP of rats with acute myocardial ischemia (AMI). Methods With 6 male Wistar rats as normal group, 18 rats were made AMI model and divided into model group, high-frequency group and low-frequency group (n=6). The high-frequency and low-frequency group were given electroacupuncture in bilateral PC6 with 100 and 2 Hz for 20 min respectively. The content of cGMP in skin around PC6, Ximen (PC4), Tianquan (PC2), Waiguan (TE5) and Zusanli (ST36) was detected by using enzyme-linked immunosorbent method after treatment. Results In model group, cGMP content increased significantly around PC6, PC2, TE5 and ST36 compared with normal group (P <0.05,P <0.001). After the treatment with high-frequency or low-frequency electroacupunture in PC6, cGMP content decreased significantly in skin around PC6, PC2, TE5 and ST36 compared with model group (P <0.05, P <0.001). Conclusion High-frequency electroacupunture or high-frequency electroacupunture used in PC6 can protect rats from the injury of AMI. The mechanism may be related to the decrease of cGMP content around the acupoint areas in heart-related meridian.

Objective To investigate the incidence, diagnosis and treatment of complications after endoscopic retrograde cholangiopancreatography (ERCP), and to explore the ways of prevention. Methods Clinical data of 930 subjects, in which 510 were older than 60, with cholangiopancreatic diseases who underwent ERCP in the past 2 years were retrospectively analyzed. Results Success rate of ERCP was 96.34% (896/930),and the postoperative complication incidence was 7.85% (73/930). Of all the complications, there were 42 cases of acute pancreatitis, among which 1 was accompanied with biliary tract infection, 4 cases of duodenum perforation, 6 delayed hemorrhage, 2 cardiac dilacerations bleeding, and 19 biliary tract infection (5 combined with infectious shock). All subjects with complications were cured except for 2 deaths. Conclusion ERCP is a safe and effective method for elderly patients. However, due to decreased organ functions and other underlying diseases, complications after ERCP in elderly patients are usually difficult to manage. The key factors in prevention of complications after ERCP includes in obedience to indications, improvement in procedure skills, treatment of accompanied diseases before and after ERCP, and active management of complications.

Objective To compare the dose distribution of the target and normal tissues in gastric cancers between three-dimension conformal radiation therapy (3DCRT) and intensity modulated radiation therapy (IMRT) plan when respiratory motion factors integrated in the plan. Methods From January 2005to November 2006, 10 patients with post-operatively radiation of gastric cancer were enrolled in this study.Planning CT were acquired conventionally with free-breath mode and the static treatment plans of the 3DCRT and IMRT were designed respectively. Probability distribution functions (PDF) were generated and convoluted with the static dose distributions from 3DCRT and IMRT plans to obtain the integrated plans. The dose distributions of the target and normal tissues were compared between 3DCRT and IMRT integration treatment plans, such as V45 of clinical target volume, V4o of liver and V15, V18 of left and right kidney.Results In the respiratory integrated treatment planning, the target volume coverage and homogeneity with IMRT are superior to those with 3DCRT ( ( V45 98%∶ 87% (t = -3. 35 ,P =0. 010) ,mean dose 46. 81 Gy ±0. 75 Gy∶45.99 Gy ± 1.12 Gy (t = -0. 31 ,P=0. 020) ). The V40 of teh liver in IMRT are smaller than those in 3DCRT ( 12%∶ 16% ;t=3.75,P=0.010). For the left kidney, the V15 and V18 in IMRT are smaller than those in 3DCRT ( (34%∶ 50% (t = 2. 17 ,P = 0. 050) and 27%∶46% (t = 3. 11 ,P = 0. 020) ),but for the right kidney, V15 and V18 in 3DCRT are smaller than those in IMRT ( ( 15%∶ 21% (t = - 2. 42,P=0.040) and 11%∶15% (t= -2.71,P=0.030)). Conclusions When respiratory motion factor integrated in the treatment plan, IMRT showed advantage both in target coverage and normal tissue sparing in the high dose region of liver and left kidney.
