OBJECTIVETo observe the effect of anisodamine (Ani) injection on the survival rate and histologic result of flaps with ischemia-reperfusion injury, so as to demonstrate the protective effect of Ani on the flap survival.

METHODSA total of 48 healthy male Wistar rats were randomly divided into model control, normal saline(NS) and anisodamine groups, with 16 rats in each group. An 3 cm x 6 cm axial flap was formed at the right lower abdomen with abdominal superficial blood vessel as the pedicle. 0.5 cm x 0.5 cm skin tissue was taken from the middle part of flaps in each group, immediately after operation, 12, 18, 24 h after operation. The superoxide dismutase (SOD), nitric oxide (NO), nuclear factor-kappaB contents in the specimens were detected. The histologic study was also performed. The flap survival rate was recorded 7 days after operation.

RESULTSFlap survival rate was (78.6 +/- 7.3) % in Anisodamine group. 12, 18, 24 h after reperfusion injury, the SOD was (103.3 +/- 3.9), (82.6 +/- 3.8), (67.5 +/- 4.6) U/mg; the NO was (5.33 +/- 2.05), (4.75 +/- 1.68), (4.15 +/-1.59) nmol/mg; the NF-kappaB was 0.211 +/- 0.039, 0.313 +/- 0.033, 0.096 +/- 0.028. The contents of SOD, NO and NF-kappaB had the statistical difference of at different time. The skin pathological changes in Anisodamine group was obviously better than those in NS group. Flap survival rate in Anisodamine group was significantly higher than that in NS group.

CONCLUSIONSIn the flap with ischemia-reperfusion injury, Anisodamine can reduce the damage of free radical, increase the blood flow, reduce the production of NF-KB, decrease inflammatory reaction. So Anisodamine can increase the survival rate of flaps with ischemia reperfusion injury.

OBJECTIVETo explore effects of Tongxinluo Capsule (TC) on platelet activating factor (PAF), vascular endothelial function, thrombolysis in myocardial infarction (TIMI) blood flow, and heart function in acute myocardial infarction (AMI) patients after delayed percutaneous coronary intervention (PCI).

METHODSTotally 80 AMI inpatients were recruited at Department of Cardiology, People's Hospital of Jiangxi Province, from Jan. 2008 to Sep.2013. Those in line with inclusion criteria were randomly assigned to TC treatment group and the conventional treatment group by random digit table, 40 in each group. Besides, another 40 healthy subjects from examinees at Outpatient Department were recruited as a healthy control group. PCI was performed after 1-week treatment. Then blood samples were collected, and then blood contents of CD62P, CD63, GP II b/III a, ET-1, NO, and plasma von Willebrand factor (vWF) levels were detected. Coronary TIMI blood flow and corrected TIMI frame count (CTFC) were determined during PCI. Meanwhile, noninvasive blood pressure (BP) and heart rate (HR) were recorded before and after PCI, and cardiac function measured. They were compared with the healty control group.

RESULTSCompared with the healthy control group, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 significantly increased, but NO significantly decreased in AMI patients (all P < 0.05). After 1-week intervention of TC, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, NO, and ET-1 significantly decreased (P < 0.05, P < 0.01). Compared with the conventional treatment group at the same time point, blood contents of CD62p, CD63, GP II b/IIIa receptor compound, vWF, and ET-1 decreased more significantly in the TC group (P < 0.05, P < 0.01), increased NO levels were also more obviously seen (P < 0.01). The aforesaid parameters changed more obviously at day 30, as compared with those changes at week 1 (P < 0.05, P < 0.01). The TIMI blood flow grade and CTFC were more obviously improved after PCI in the two treatment groups. Better TIMI blood flow was seen in the TC group. TIMI level 3 blood flow rate was higher in the TC group than in the conventional treatment group with statistical difference (P < 0.05). The left ventricular ejective factor (LVEF) after PCI was obviously elevated in the TC group and the conventional treatment group (P < 0.01), and the improvement was more obviously seen in the TC group (P < 0.05). There were 6 cases of recurrent angina, 3 cases of ventricular tachycardial (VT)/ventricular fibrillation (VF), 6 cases of heart failure (HF), 1 case of cardiac sudden death in the conventional treatment group, with the total incidence of cardiovascular events being 40% (16/40). There were 2 cases of recurrent angina, 2 cases of VT/VF, 2 cases of HF, no cardiac sudden death in the TC treatment group, with the total incidence of cardiovascular events being 15% (6/40). There was statistical difference in the recurrent rate of cardiovascular events between the two groups (χ² = 2.27, P < 0.05).

CONCLUSIONTC not only could prevent coronary embolism of AMI patients after delayed PCI, attenuate vascular endothelial injury, but also could improve TIMI blood flow, and strengthen cardiac systolic function.

Microwaves can be directly transformed into heat inside materials because of their ability of penetrating into any substance. The degree that materials are heated depends on their dielectric properties. Materials with high dielectric loss are more easily to reach a resonant state by microwaves field, then microwaves can be absorbed efficiently. Microwave irradiation technique with the unique heating mechanisms could induce drug-polymer interaction and change the properties of dissolution. Many benefits such as improving product quality, increasing energy efficiency and reducing times can be obtained by microwaves. This paper summarized characteristics of the microwave irradiation technique, new preparation techniques and formulation process in pharmaceutical industry by microwave irradiation technology. The microwave technology provides a new clue for heating and drying in the field of pharmaceutics.

OBJECTIVETo systematically evaluate the efficacy and safety of kidney-tonifying traditional Chinese medicine in the treatment of male infertility.

METHODSBased on the principles and methods of Cochrane systematic reviews, we searched CNKI, VIP, and Wanfang databases from inception to December 2012 for randomized controlled clinical trials addressing the treatment of male infertility with kidney-tonifying traditional Chinese medicine. According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and conducted meta-analysis using the RevMan 5. 2 software.

RESULTSTwenty trials involving 2,272 patients were included, and the sample size of each study was from 60 to 270 cases. All the studies were graded as of poor quality, with Jadad scores of no more than 3 points. The results of meta-analysis showed that the total effectiveness rate of traditional Chinese medicine versus Western medicine on male infertility was RR = 1.71, 95% CI 1.19-2.47, and that of Chinese-Western combined therapy versus Western medicine was RR = 1.15, 95% CI 1.01-1.30. Both traditional Chinese medicine and Chinese-Western combined therapy showed a significantly better total effectiveness than Western medicine alone in improving the pregnancy rate without serious adverse reactions.

CONCLUSIONDue to the poor methodological quality and high heterogeneity of the included studies, the evidence for the efficacy and safety of kidney-tonifying traditional Chinese drugs in the treatment of male infertility is of but limited value, and further validation is needed by more high-quality studies.

Objective To evaluate clinical effect of simultaneous kidney-pancreatic transplantation(SKPT) with portal venous and enteric drainage. Method Between June 2001 and June 2004, six insulin-dependent diabetes mellitus(IDDM) and renal failure patients underwent this procedure. The venous drainage of the graft was established between donor′s portal vein and recipient′s superior mesenteric vein. The exocrine secretion was drained into proximal jejunum via side-to-side anastomosis between donor′s duodenum and recipient′s proximal jejunum. Steroids, mycophenolate mofetil, tacrolimus and Zenapax were used as immunosuppressants. Results Procedures were successful in all 6 cases. Excellent renal function and euglycemia were achieved in 4 cases. Follow-up of 4-34 months on the 4 survivers found excellent kidney-pancreatic function without any rejection episode. Two patients died perioperatively due to sepsis secondary to pancreatic leakage and drug toxicosis of excessive FK506. Conclusion Our preliminary experience suggests that simultaneous pancreas-kidney transplantation with enteric and portal drainage is reliable procedure for the treatment of IDDM with renal failure.
