OBJECTIVE:To provide for rational use of Tripterygium glycosides tablet clinically. METHODS:The utilization of Tripterygium glycosides tablet were collected from hospital information system(HIS)in our hospital during Jun. 2012-Jun. 2014. Then the data about the basic information,patients’age,departments and diagnosis,were analyzed by the Excel. RESULTS:The application of Tripterygium glycosides tablet remained stable since Jun. 2012. There were 4 600 prescriptions in average every year, and the age of patients was distributed from 11 to 90. Tripterygium glycosides tablet was mainly used in rheumatology department (52.11%),followed by TCM rheumatology department(20.62%),skin disease and venereal disease department(18.15%),ne-phrology department(3.52%)and integrated traditional and western medicine cardiology department(1.77%). It was mainly used to treat rheumatoid arthritis,Sjogren's syndrome,polymyalgia rheumatica,osteoporosis and nephrotic syndrome. CONCLUSIONS:The application of Tripterygium glycosides tablet as immunosuppressant is widely used,but the age of patient is with wide distribu-tion;the narrow gap exists between minimum effective dose and minimum lethal dose;so ADR should be concerned closely.

The compound that distributes in the herbs with one common effect was named as "co-effect compound" (CEC). The CECs of three traditional Chinese medicine(TCM) effects, purgative, relieving pain and clearing heat, had been found and studied. A strong corresponding relationship was found between the pharmacological activities of CECs and the TCM effect they belong to. The study shows that it may be a feasible method to connect traditional effect of TCM with modem pharmacological activity.

OBJECTIVE: To establish the rapid PCR amplification program and system and to verify the technical indexes. METHODS: PCR multiplex and capillary electrophoresis detection of 24 autosomal STR loci and one Y-STR loci using the 6-color fluorescence marking technology, as well as A melogenin and Y-InDel. Meanwhile, sensitivity, specificity, identity, stability, mixing and a batch of sample tests were investigated, and the genotype of various routine samples and degraded, exfoliated cell samples were observed. RESULTS: The sensitivity of the system was 0.062 5 ng. In addition, the genotype could be detected accurately only around 65 min via rapid amplification. The species-specificity was high and the genotyping of all kinds of dry blood specimens of filter paper and mixed, degraded, exfoliated cell samples were accurate. CONCLUSION The rapid amplification system can significantly improve the detection rate, and obtain accurate and stable genotyping results, which may be important implications for the establishment of STR database and study on population genetics and forensic identification.

Objective To explore acute toxicity of succimer on mice.Methods Twenty Kunming mice(10 males and 10 females) weighting approximately (21.2?2.3)g were acclimatized for 3 days prior to dosing,then were divided into control group and experiment group with 10 mice in each group according to body weight.Fasted for 12 hours,the mice in experiment group received intragastric administration of 160mg DMSA in deionized water in 24 hours,and the control group received the same volume of deionized water,and then they were observed for 7 days.Blood was collected into heparinized-tubes by removal of eyeball.All mice were sacrificed and brain,heart,liver and kidney were removed and washed with normal saline.The activity or amount of BUN,Scr,AST,ALT,SOD, GSH-PX and MDA were analyzed.Results (1)Given 160rag DMSA in 24 hours,gastrointestinal symptoms were main side effects.During the observation,experiment group lost weight due to the decrease of food-intake ,and some mice had slight hydroabdomen.(2)High dose of DMSA caused a significant inhibition of GSH-PX(P0.05).The hepatic cell was damaged accord- ing to the significant raise of MDA in liver(P0.05),which was related to acute toxicity on liver.Conclusion Succimer could inhibit the antioxidarrt systems and could do damage to liver and kidney.

OBJECTIVETo explore the value of phase ordering with automatic window selection(PAWS)and simultaneous multiple volume(SMV)algorithm double respiratory navigator-gated two-dimensional(2DNAV)dual inversion recovery(DIR)fast spin echo(FSE)high-resolution black-blood coronary artery wall magnetic resonance imaging(MRI)and evaluate its advantages and limitations.

METHODSPAWS and SMV 2DNAV DIR FSE high-resolution black-blood MRI was performed in 21 healthy volunteers. The images were evaluated qualitatively by using four grades(grade 0can not evaluate;grade 1bad;grade 2good;grade 3perfect). Images defined as grade 0 and grade 1 were excluded and those defined as grade 2 and 3 were evaluated further. Thickness of proximal(or middle)segment of right coronary artery(RCA)and left anterior descending branch(LAD)were measured. The difference of wall thickness was analyzed by using two-tailed independent sample t-test. P values of less than 0.05 were considered statistically significant.

RESULTSAmong the 38 slice images,31 slices(RCA13 slices,LAD18 slices;grade 214 slices,grade 317 slices)were obtained for further evaluation. The mean thickness of RCA and LAD was(0.94±0.16)and(0.89±0.15)mm,respectively,and the difference was not significant(t=-0.790,P>0.05).

CONCLUSIONPAWS and SMV algorithm 2DNAV DIR FSE high-resolution black-blood MRI has certain clinical value for coronary artery wall imaging.

OBJECTIVETo observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.

METHODSWe treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.

RESULTSStapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).

CONCLUSIONCircumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.

OBJECTIVE: To observe the different tissue distributions of the adriamycin polybutylcyanoacrylate nanoparticle (ADM-PBCA-NP) in the mice body after the injection via lateral tail vein, and to study the liver targeting effects of ADM-PBCA-NP in different diameters on normal mice livers. METHODS: One hundred and eighty mice were randomly divided into 6 groups with 30 mice in each group: non-conjugated free ADM (Group 1); (22.3+/-6.2) nm in diameter ADM-PBCA-NP group (Group 2); (48.6+/-9.2) nm ADM-PBCA-NP group (Group 3); (101.9+/-20.3) nm ADM-PBCA-NP group (Group 4); (143.5+/-23.5) nm ADM-PBCA-NP group (Group 5), and (194.2+/-28.4) nm ADM-PBCA-NP group (Group 6). A single dose of either conjugated or free adriamycin equaled 2 mg/kg of body weight was delivered via the tail vein. Five mice in each trail were sacrificed at 5, 15, 30 minutes, 1, 5 and 12 hours after the injection, respectively. The adriamycin concentrations in the collected livers, kidneys, spleens, hearts, lungs and plasma were demonstrated using a high performance liquid chromatography with fluorescence detector. RESULTS: Compared with that of the control group, adriamycin was hardly detected in the heart muscles of the treatment groups (P<0.05). The nanoparticle-conjugated adriamycin was cleaned up quickly from the kidney tissues. The adriamycin concentrations of the mice liver and spleen in the experimental groups was significantly higher than those in the control group, except for the group with the nanoparticles diameters of (22.3+/-6.2) nm (P<0.05). The ADM-PBCA-NP in (101.9+/-20.3) nm diameter had the highest liver distribution, and the second highest adriamycin distribution in the liver was the group of (143.5+/-23.5) nm diameter (P<0.05). Adriamycin was released slowly in the liver during the detection period in the experimental groups. ADM-PBCA-NP in (22.3+/-6.2) nm diameter was not distributed in the tissues of the livers, kidneys, hearts, spleens, and lungs. CONCLUSION ADM-PBCA-NP with a 100 - 150 nm diameter range has the best liver targeting with slow medicine release. It also decreases the medicine distribution in the heart and other organs. In the treatment of liver cancer, the polybutylcyanoacrylate nanoparticle system has a good liver targeting ability, which increases the anticancer activity and markedly decreases the toxicity of adriamycin.

BACKGROUNDPodocyte has inflammatory role in the development of diabetic nephropathy (DN). Mycophenolate mofetil (MMF), an anti-inflammatory agent, can suppress macrophage infiltration and reduce renal injury in streptozotocin-induced diabetic rats. Angiotensin II receptor blocker (ARB), another renal protecting agent, can decrease podocyte loss in DN. In this study, we detected the expression levels of monocyte chemoattractant protein-1 (MCP-1) and nephrin to evaluate podocyte's role in inflammatory reaction in DN, observe and compare the effect of MMF alone and in combination with valsartan, on preventing podocyte loss in streptozotocin (STZ) induced diabetic rats.

METHODSDiabetic model was constructed in uninephrectomized male Wistar rats by single peritoneal injection of STZ (65 mg/kg). The successfully induced diabetic rats were randomly divided into four groups: diabetes without treatment group (DM), valsartan treated group (DMV), MMF treated group (DMM), and combined therapy group (DMVM). Normal rats of the same sibling were chosen as control (NC). At the end of the 8th week, serum biochemistry, 24-hour urinary protein (UP) and the ratio of kidney weight/body weight (RWK/B) were measured. The rats were sacrificed for the observation of renal histomorphology through light and electron microscope. Nephrin, desmin and MCP-1 levels were detected by semi-quantitative immunohistochemical assays. Real-time quantitative PCR was used to detect the mRNA levels of nephrin and MCP-1.

RESULTSCompared with group NC, serum glucose level, 24-hour UP and RWK/B in group DM were significantly higher (P < 0.01), and the nephrin mRNA level in DM group was significantly lower (P < 0.05). The nephrin mRNA expression levels in group DMV, DMM and DMVM were all higher than that of DM group (P < 0.05) and no significant differences were found among the three treatment groups (P > 0.05). Treatment with MMF, valsartan or their combination could significantly decrease the 24-hour UP and RWK/B, and suppress glomerulosclerosis and interstitial fibrotic lesions in diabetic rats. In diabetic rats, the high expressions of desmin and MCP-1 in kidney were suppressed by valsartan, MMF or their combination.

CONCLUSIONSPodocytes are involved in the inflammatory reaction of diabetic rats. MMF could suppress MCP-1 and desmin expression, enhance nephrin expression, and attenuate proteinuria in diabetic rats. The combined therapy of valsartan and MMF did not show any superiority over monotherapies on renal protection. MMF may have renoprotective effect in early stages of diabetic nephropathy through preventing podocytes loss and anti-inflammatory activity.

OBJECTIVETo investigate the feasibility, advantages and efficacy of implantation of left atrial and ventricular epicardial dual chamber pacemaker to treat pediatric complete atrioventricular block.

METHODEleven children with median age 4.0 years (0.5-7.6 years) diagnosed as complete atrioventricular block resisting to drug therapy received implantations of left atrial and ventricular epicardial dual chamber pacemakers. Six were male and five female. Temporal or permanent right ventricular pacing was used for all of them before implantation of left atrial and ventricular epicardial dual chamber pacemakers. Three cases showed cardiac dysfunction. Left lateral thoracotomy was performed at 4th intercoastal space along anterior axillary line under general anesthesia, the pericardium was incised vertically anterior to the phrenic nerve, two pacing leads were individually located at left atrial appendage and left ventricular lateral wall. After all the parameters were detected to be satisfactory, a pouch was made at left abdomen under coastal margin. Dual chamber pacemaker was connected with pacing leads through subcutaneous tunnels. The sizes of heart chambers, cardiac functions, parameters of pacemaker, sensitivity, pacing status, PR interval and QRS interval were closely followed up post-operatively.

RESULTImplantations of pacemakers were successful for all of the patients with no complications associated with operations. Preoperative electrocardiograms showed QRS interval (180 ± 33)ms under right ventricular pacing, it decreased to (140 ± 24)ms after implantation of left atrial and ventricular epicardial dual chamber pacemaker, significantly lower than right ventricular pacing (t = 8.8, P < 0.05) . Atrioventricular (AV) interval was set at 90 ms, PR interval (124 ± 4)ms. Echocardiograms performed within 2-3 days after implantation of left atrial and ventricular epicardial dual chamber pacemakers showed that for the 3 cases who were previously under right atrial and right ventricular dual chamber pacing presenting cardiac dysfunction, their left ventricular diastolic diameter (LVDd) decreased from (46.3 ± 12.5) (32.0-55.0) ms to (44.7 ± 12.0) (31.0-53.0) mm and left ventricular ejection fraction (LVEF) increased from 30% ± 15% (18%-47%) to 44% ± 18% (33%-65%). During 2-14 months' follow up, LVEF increased progressively which became significantly higher than before (65% ± 8% vs. 30% ± 15%, t = 5.6, P < 0.05) . Cardiac chamber sizes and left ventricular systolic function for the other 8 patients maintain normal during follow up. Pacing status and sensitivity were satisfactory for all these patients during follow up.

CONCLUSIONImplantation of left atrial and ventricular epicardial pacemaker might be considered for children diagnosed as complete atrioventricular block for whom endocardial pacemaker could not be implanted, due to its utmost protection for cardiac function with minimal injury and its ability to prevent or reverse pacemaker syndrome. Left atrial and left ventricular epicardium should be regarded as the first-choice and routine locations for epicardial pacing.

OBJECTIVETo evaluate the validity and reliability of Thread-tooth Arc-track Screw Plate System (TASPS) in the fixation fusion through expandable channels.

METHODSFrom August 2007 to August 2010, 108 patients with lumbar instability were treated with surgery, including 61 males and 47 females, ranging in age from 26 to 57 years, with an average of 41 years. All the patients were divided into two groups : minimally invasive fusion group and traditional operation group (54 patients in each group). The patients in the minimally invasive fusion group were treated with self-designed TASPS to conduct the fixation fusion through expandable channels by minimally invasive pedicle screw; and the patients in traditional operation group were treated with traditional interbody fixation fusion by pedicle screw. The data were collected and investigated at the 1st week, 3rd month and 1st year postoperatively. The comparative parameters of two groups contained the total operation time, the implanted time, the total amount of bleeding; the VAS score, ODI score and improvement rate at each investigated period; the intervertebral space height of preoperative and postoperative periods; the inefficiency rate of implantation and the fusion rate of postoperative period.

RESULTSAll incisions were healed by first stage without any complications such as dural tear, injury of nerve root or cauda equine, intervertebral space infection. The patients in the minimally invasive fusion group needed longer operative time than that of the traditional operation group, but had less total amount of intraoperative and postoperative bleeding and shorter implanted time of pedicle screw than those of the traditional operation group. The VAS scores of two groups at the 1st week after operation significantly decreased compared with that of the 1st day before the operation, and the difference was of high statistical significance. And the VAS scores of two groups at the 3rd month and 1st year after operation also significantly decreased compared with that of the 1st day before the operation, and the difference was highly statistically significant. By comparing the VAS score and ODI score at the 1st week, 3rd month and 1st year postoperatively, the results showed that the VAS score and ODI score of the minimally invasive fusion group were all lower than those of the traditional operation group, and the differences were of high statistical meaningfulness. After 1 year, the improvement rate of the minimally invasive fusion group was (77.46 +/- 6.34)%, while that of the traditional operation group was (72.73 +/- 4.49)%, and the difference was highly statistically significant (P < 0.01). The intervertebral space heights of two groups remarkably increased. At the 3rd month after operation, the difference of intervertebral space heights of the two groups was of no statistical significance. At the 1st year after operation, intervertebral space heights of the two groups were lost to some extent, but the height of the minimally invasive fusion group was higher than that of the traditional operation group, and the difference was statistically significant. The fusion rates of the two groups after 1 year were 100%.

CONCLUSIONThe fixation fusion through expandable channels by minimally invasive pedicle screw possesses the characteristics of fewer traumas, less intraoperative blood loss, less postoperative pain and rapid recovery. Since its intervertebral fusion rate is similar to the open surgery, it can be viewed as one effective approach for the treatment of lumbar instability diseases. And TASPS is reasonably designed, easy to install and reliably fixed with good reduction effect, which can be applied through expandable channels.
