Objective To discuss the protection of parathyroid and application of nano-carbon suspen-sion in thyroid surgery .Methods 80 cases were randomly divided into 2 groups:the experimental group which were injected nano-carbon into thyroid during thyroidectomy , and the control group without any injection .Results There were 5 cases with hypocalcemia and 5 cases with PTH decrease in the experimental group , and there were 15 cases and 14 cases respectively in the control group .Pathological results showed that misresection of par-athyroids occurred in 6 cases of the control group(11 parathyroid glands)were while it didn't happen in the experi-mental group .Conclusion Nano-carbon can help to identify and protect the parathyroid , decreasing the proba-bility of parathyroid gland damage during thyroid surgery .

Myocardial ischemia/reperfusion injury ( MI/RI) is a pathophysiological phenomenon commonly seen during thromboly-sis, percutaneous transluminal coronary angioplasty ( PTCA ) , and coronary artery bypass grafting ( CABG ) . It is defined as restoration of blood flow to a previously ischemic region followed by complex pathological events leading to tissue injury greater than the original ischemic insult. Many experimental interven-tions have been reported to protect the ischemic myocardium in experimental animals; however, with the exception of early reperfusion, none has been translated into clinical practice. The root of Panax notoginseng ( Burk. ) F. H. Chen ( PN) is one of the iconic herbs in traditional Chinese medicine. Traditional pharmacopeia recommended it among the most efficacious herbs for‘promoting blood circulation ’ and hemostasis. Inspired by this, in the last decade, a large number of modern investigators made substantial efforts to search the PN activities against a vari-ety of MIRI. The systematic review was performed according to the protecting drug of the MIRI development guidelines.

The damage of tissue increases dramatically after reperfusion of blood supply to ischemic tissues.Immune response is one of the key reasons of ischemia-reperfusion injury.Th1 /Th2 generally stays balanced in normal states.Under the envi-ronment of ischemia reperfusion,Th1 /Th2 shifting let Th1 domi-nant to mediate cellular immunity.Excessive immune reaction may cause cell apoptosis and tissue damage.Recent studies showed that induction of transferring Th1 dominant to Th2 domi-nant was feasible for the treatment of ischemia-reperfusion inju-ry.With the progress of modern drug development paradigm“multi-composition,multi-target”,Chinese medicine has advan-tages in treating complex diseases.This paper summarizes the research of the relationship between Th1 /Th2 imbalance and is-chemia-reperfusion injury,together with the prospects of tradi-tional Chinese medicine with multi-target effect in ischemia-reperfusion injury.

Objective To investigate the changes and correlative factors of natural killer(NK)cells and T lymphocyte subpopulations levels in neonates with hypoxic-ischemic encephalopathy(HIE).Methods Peripheral blood samples were collected from 50 neonates with HIE.The percentages of NK cell(CD3~-CD_(16)~+CD_(56)~+) and T lymphocyte subpopulations including CD3~+,CD4~+,CD8~+ and CD4~+/CD8~+ ratio were determined by Flow Cytometr(FCM).Meanwhile,20 healthy neonates were served as controls.Results (Le)-vels of NK cell,CD3~+,CD4~+,CD8~+ and CD4~+/CD8~+ ratio in neonates with HIE were significantly lower than those in control group(all P0.05).Spearman correlation analysis showed that there were negative correlation between the NK cell,CD3~+,CD4~+,CD4~+/CD8~+ ratio and stages of HIE(all P0.05). Linearregression analysis showed that there was a positive correlation between NK cell and gestationalages((P

Objective To explore the effect of Melatonin(MT) on CD4+CD25+ regulatory T cell (CD4+CD25+Tr)and airway inflammation in asthmatic rat.Methods Thirty-two SD rats were randomly divided into 4 groups,8 rats in each group.Asthmatic group:rats were immunized on day 1 and 7 by intraperitoneal inject of mixture of ovalbumin(OVA) and aluminumhydroxide.From day 14,the animals were allenged with aerosolized OVA for 20 min per day for 7 consecutive days.MT group:OVA-sensitized rats were injected intraperitoneally with 0.1 mg/kg MT 30 min before each OVA challenge.Dexamethasone group:OVA-sensitized rats were injected intraperitoneally with 0.5 mg/kg Dexamethasone 30 min before each OVA challenge.Control group:OVA for inhalation and MT for intraperitoneal injection was replaced with saline.After the last challenge,peripheral blood was stained to count the percentage of eosinophil(EOS).Then the rats were lavaged and total leukocytes counts in bronchoalveolar lavage fluid(BALF) were performed after staining with Wright-Giemsa staining.The EOS counts around the airway was counted after the histological section of lung staining with hematoxylin and eosin staining.The serum level of immunoglobulin E(IgE) was detected by immunoenhancement.The change of CD4+CD25+Tr was assessed with flow cytometry.SPSS 10.0 software was applied to analyze data. Results In asthmatic rats,the CD4+CD25+ Tr/ CD4+T cells ratio had significant negative relationship with the EOS counts around the airway and the total leukocytes counts in BALF (r=-0.73 P0.05).There was a significant decrease in the percentage of the eosinophils in peripheral blood,the eosinophil counts around the airway,the total leukocytes counts in BALF and the serum level of IgE in MT group compared with asthmatic group (Pa

ObjectiveTo compare the efficacy and side effects of ilioinguinal/iliohypogastric nerve blockades and rectal paracetamol after pediatric inguinal hernia repair.MethodsNinety children undergoing half inguinal hernia repair were randomly divided into 3 groups:nerve block group(n=30),paracetamol group(n=30) and control group(n=30).After basal anesthesia,ilioinguinal/iliohypogastric nerve blockades was administed in nerve block group,paracetamol group received rectal paracetamol,control group had not any medication.Every child was oberserved 1,3,6,8 h postoperatively for pain score,overall satisfaction were evaluated by parents,furthermore,evaluation of distress for children such as nausea,vomiting and delayed femoral nerve palsy was made.ResultsPain scores were significantly lower in nerve block group and paracetamol group during the postoperative follow-up 1,3 and 6 h.Overall satisfaction in nerve block group and paracetamol group were significantly higher than control group.The incidence of delayed femoral nerve palsy in nerve block group was higher than paracetamol group(F=4.22P

Objective To discuss the role of therapeutic drug monitoring (TDM) in pharmaceutical care by successful intervention of severe drug-drug interaction in 3 patients with hematological disease treated with voriconazole and rifampin.Methods Three patients with hematological disease were monitored for the plasma concentration of voriconazole before,during,and after the concomitant use of rifampin.The severity of this drug interaction was revealed,risks for developing invasive fungal infection and tuberculosis dissemination after chemotherapy were evaluated based on the TDM results,and alternative regimens were recommended.Results Voriconazole plasma concentration was normal at baseline but significantly depressed after combination with rifampin in all 3 cases.Concomnitant use of rifampin leads to a rapid decline in plasma concentration of voriconazole in 2-3 days,and withdraw of this enzyme induction effect takes 8-10 days after discontinuation of rifampin.Conclusion TDM is a helpful tool for providing pharmaceutical care,it helps to objectively visualize the degree of clinically important drug-drug interactions.Clinical evidence together with TDM results suggests high risk for developing invasive fungal infection and tuberculosis dissemination in hematology patients while using this combination therapy.Discontinuation of rifampin was suggested and accepted.For these patients,combination of voriconazole and rifampin should be avoided.
