Nicotinamide N-methyltransferase (NNMT) is a S-adenosyl-L-methionine (SAM) dependent cytoplasm enzyme,which plays a vital role in the biotransformation and detoxification of many drugs and xenobiotic compounds.Recent studies have revealed abnormal expression of NNMT in many tumors,which may contribute to tumorigenesis and tumor development and radiotherapy or chemotherapy resistance.

Objective To study the effects of Alprosladil and Glutathione therapy on patients with drug-induced acute renal damage. Methods 108 patients with drug-induced acute renal damage were divided into three groups at random. The patients in gruoup A (n=36) received 10?g Alprosladil injection once a day, the patients in group B (n=42) received both 10?g alprosladi and 1200mg glutathione injection once a day additionally, and the patients in group C (n=30) received 10mg dpamine injection once a day. The course of treatment of the three groups was 2~4 weeks. Results The effective rates for acute renal failure in groups A, B and C were 85 7%, 96% and 61% respectively. The effective rates for proteinuria, hematuria, N-acetyl-?-glucosaminidase(NAG)and retinol-binding protein(RBP) in urine were 70%, 78%, 76% and 80% in group A, 85%, 90%, 90% and 90% in group B, and 50%, 50%, 42% and 58% in group C respectively, which had significant difference among the three groups (P

Chinese Traditional and Herbal Drugs 2018;49(21):5125-5133
Objective To predict the pharmacological effect and targets of main chemical components of Lindera aggregata, and construct the multi-target network. Methods The potential targets and pathways of linderene acetate, isocembrol, laurolitsine, β-humulene, chamazulene, laurotetanine, and lindestrenolide, selected as the representative compounds of oils, alkaloids, and furan sesquiterpene lactones from Linderae Radix, were predicted by methods of network pharmacology. The pharmacodynamic effects of main chemical constituents of L. aggregata was analyzed by data integration. Results The in silico prediction results showed that seven compounds of L. aggregata affected 20 related pathways through 40 potential targets. The pathways were involved in several links including inflammatory, analgesic, gastrointestinal movement regulation, anti-oxidation, antitumor, liver injury protection, and immunoregulation. The various components showed common targets, pathways, and pharmacodynamic effects and had different emphases. Conclusion The pathways related to L. aggregata oils, alkaloids, and furan sesquiterpene lactones were connected by the common targets, showing the synergistic effect of different compounds by acting on multi-targets and multi-pathways. This study provides references for systematic exploration on the pharmacological actions and mechanisms of L. aggregata.

Objective To investigate the efficacy and safety of a schedule of 2 cycles' high-dose dexamethasone (HD-DXM) as an initial therapy in adults immune thrombocytopenia (ITP), and compare with conventional dose prednisone therapy. Method A total of 59 newly diagnosed ITP patients were divided into 2 groups randomly. In 30 patients ( Dexamethasone group), oral HD-DXM was administered at 40 mg/d for 4 consecutive days, repeated one week later, and then failed to maintain. In the remaining 29and then gradually tapered. Results For short-term efficacy, after 1 and 2 weeks of treatment, the response rate in Dexamethasone group was significantly higher than that in Prednisone group (50. 0% vs 24. 1%, P <0. 01; 73.3% vs 55.2%, P <0. 05 ), while 3 weeks later, there was no remarkable difference between the two groups(83.3% vs 68.9%, P > 0. 05 ), though the response rate in Dexamethasone group remained higher. For long-term effect, at the end of the 2nd and 3rd months of follow-up, the relapse rate in Dexamethasone group was significantly lower than that in Prednisone group(24. 0% vs 40. 0%, P < 0. 05;32.0% vs 65. 0%, P < 0. 01 ), while at the end of the 1st month of follow-up, there was no significant difference( 16. 0% vs 20. 0%, P >0.05 ). In addition, it's well tolerated and no complications such as severe infection or Cushing syndrome were complained in Dexamethasone group. Conclusion HD-DXM possesses an advantage over conventional dose prednisone therapy in efficacy and safety.

Aim To set up a novel animal model of intra-abdominal adhesion and to determine whether the tissue plasminogen activator activity (PAA) in exudate can be taken as an indicator to judge the formation of the adhesion. Methods Rats were randomly divided into 2 groups. Each animal in both groups was opened the abdominal cavity via midline laparotomy without any disinfectant measures. 2-cm section from the cecal end was clamped and ligated, 1-cm cecum of the section was cut, and another 1-cm end from the ligated site was kept. After the content in the end was extruded, the cecum was put back without using any antibacterial agent. Before the skin closure, an effective combination AMD (allantoin, metronidazole and dexamethasone in combination), was given (ip) according to 1.5 ml per 100 g body weight (60.6 mg·kg-1). The control group was injected (ip) the same volume of normal saline. After 6 h, the exudate was extracted from drainage-tube, with the rats varying posture, and after 1 kw, the rats were killed for examining the intra-abdominal adhesion. The values of PAA of exudate in both groups were analyzed by the relative operating characteristic curve (ROC). Results In the control group, all 20 rats formed the adhesions, the amount of exudate=(1.25±0.09) ml, the number of WBC(×103)=(23.1±6.6) mm3 and PAA=(0.9±0.4) IU·ml-1 in the exudate of abdominal cavity. In AMD group, however, there was not the adhesion formations (0/20), the amount of exuade was (0.52±0.04) ml (P<0.01), the number of WBC (×103) (10.6±4.2) mm3 (P<0.01), and PAA (23.1±6.6) IU·ml-1(P<0.01) in exuade.ROC analysis indicated that if PAA >1.24 IU·ml-1 in the exuade, the adhesion was difficult to form, and vice versa. Conclusion This animal model can be taken as an effective tool to evaluate the human adhesion related to multi-links on the pathogenesis, and the PAA in exudate an indicator to judge intra-abdominal adhesion formation.
