Berberine is a taste of traditional Chinese medicine.With the progress of research on pharmacology and mechanism of drug action of extensive research,the new mechanism of berberine was revealed through a series of clinical trials,the clinical indications continue to expand,and berberine has a therapeutic effect in digestive and endocrine system disease.The current study confirmed that berberine not only has the broad-spectrum antibacterial activity,but also plays a strong anti-inflammatory and immune regulatory role,which makes more and more research began to concern its application value in the diseases of respiratory system.The strong anti-inflammatory effect of berberine cau effectively relieve the airway inflammation of patients who are suffering from chronic obstructive pulmonary,and the broad-spectrum antibacterial effect brought hope for the treatment of tuberculosis and pneumonia.The subsequent animal and clinical studies have confirmed that berberine can effectively improve the symptoms of respiratory system diseases,and play a role in the treatment.

OBJECTIVE:To establish the quality standard of shuangbai tincture.METHODS:The rhubarb and cortex phellodendri in shuangbai tincture were identified qualitatively by TLC.The content of emodin in this preparation was deter-mined by HPLC.RESULTS:In the TLC of the testing samples,the corresponding positions of standard rhubarb and standard cortex phellodendri respectively showed the same color of speckles.The linear range of emodin was0.1176?g～2.3520?g(r=0.9994)and the average recovery was98.81%(RSD=0.45%).CONCLUSIONS:This method is simple,accurate and repro-ducible,and suitable for the quality control of shuangbai tincture.

Objective To investigate the effect of different anesthesia methods on perioperative body temperature. Methods Eighty patients undergoing esophagus cancer resection were randomized into two groups of combined general and epidural anesthesia(GEA, group A,42 cases) and general anesthesia(GA, group B, 38 cases). Epipharynx and peripheral temperatures were recorded at the same time every 30 minutes for 3 hours after induction. Epipharynx temperature was recorded than after when circulating water mattresses and fluid warming were used to rewarming. The incidence of postoperative shivering was recorded. Results The peripheral temperature was gradually decreased after induction in both groups. The core temperature was decreased quickly within the first 1 hour in both groups, which was reduced slowly within the next two hours with a greater magnitude of temperature reduction in group A than that in group B(P<0.05). The incidence of shivering was higher in group A than that in group B during warming up. Conclusion The patients undergoing long procedures such as esophagus cancer recection under GEA is at more risk for hypothermia than those under GA.

Objective To investigate the therapeutic potential of brain-derived neurotrophic factor (BDNF) and Schwann cells(SCs) in experimental autoimmune neuritis (EAN) and assess the effect and mechanism.Methods EAN model was established by immunization of Lewis rats with 400 μg of specific peptide P2(57-81)and complete Freund adjuvant.In the therapy group,the SCs (n =28) and the combination of BDNF administration and SCs (n =48) were labeled by the nuclear fluorescent dye injected into the intracerebroventricularly in 14 d after immunization.Transplanted cell migration tracking respectively were at 25,35 and 45 days after immunization.The rats were observed for signs of disease daily and subjected to clinical score,of which the sciatic nerves were subjected to histopathological examination (hematoxylin eosinstaining,luxol-fast-green and immunohistochemical staining).The inflammatory cell infiltration and demyelination were assessed,and the CD4,CD8,CD68,S-100 and nerve growth factor (NGF) positive cells numbers were compared among the 3 different groups.Results AIl the rats had the neurological deficits.Compared with control group,there were no significant differences in SCs therapy group.In SCs + BDNF therapy group,the recovery of paralytic symptom was faster and the score was lower after immunization 45 d.After immunization 25 and 35 days,both the inflammatory cells infiltration (EAN model group:325.8 ±10.8,221.4 ± 35.2;SCs + BDNF transplantation group:307.3 ±4.6,197.2 ± 16.8; t =2.172,P =0.031 ;t=3.756,P=0.000) and the expression of CD4+,CD8+ T cells and CD68+ macrophages were reduced.After immunization 35,45 days,the demyelination degree (EAN model group:3.4 ± 0.5,2.9 ± 0.8 ; SCs +BDNF transplantation group:2.9 ±0.8,2.3 ±0.5) was reduced (t =-7.408,P =0.000;t =-6.092,P =0.000),the expression of S-100 is higher,and NGF was lower than the control group in each time point after immunization.Conclusions SCs transplanted into the cerebellar ventricle of animals can migrate into the sciatic nerve.The combination of BDNF administration and SCs transplantation may represent an effective strategy by reducing inflammation reaction,improving the expression of S-100 in the donor cell,and reducing NGF irritability heighten in sciatic nerve.However,delivery of SCs alone is inefficiency to the treatment of EAN.

OBJECTIVE: To evaluate the use of oral hypoglycemic drugs in our hospital in order to provide an reference for rational use of drugs in clinic. METHODS: DDDs, sales volume, and daily expenses of drugs in our hospital from 2001to 2003 were analyzed with the method of DDD analysis. RESULTS: The varieties, quantities and sales volumes of oral hypoglycemic drugs increased year by year. The top 3 hypoglycemic drugs in respect of DDDs were dimethylbigmide, gliclazide, and glipizide. The top 3 hypoglycemic drugs in respect of sales volume were glipizide, acarbose, and dimethylbimide. The ratio of sales volume sequencing to that of DDDs was between 0.2～4. CONCLUSIONS: Gliclazide and dimethylbimide are most widely used and their prices are reasonable; Acarbose is expensive, and its sales volume has not grown in pace with DDDs.

The value of dobutamine 99m橳c-MIBI SPECT (DBA-SPECT) for detecting coronary artery disease was assessed in 56 patients with chest pain. Exercise ECG, DBA-ECG and DBA-SPECT were obtained. The hemodynamic changes in DBA infusion are similar to that in exercise test. In 21 patients who had coronary angiogram,the sensitivity,specificity and accuracy were 87. 5% ,76. 9% ,81. 7% ,respectively in DBA-SPECT;75. 0%, 92. 3%, 85. 0%, respectively in DBA-ECG,and 87. 5%,46. 2% ,61.9% ,respectively in exercise ECG test. The results showed that DBA-SPECT is a feasible safe and non-invasive method for detecting coronary artery disease.

Calmodulin(CaM),as major intracellular Ca 2+ signal transductor,is a ubiquitous, multifunctional protein in eukaryotic cells,invovled in a wide variety of cellular processes . Study of the structure and molecular recognition mechanism of CaM helps better understanding intracellular Ca 2+ signaling system and molecular recognition of protein-protein interaction,giving new insight into medicine development and clinical therapy. This paper reviews progress in the studies of molecular recognition of calmodulin in recent past years.

Objective Clinical parenteral nutrition( PN) support still lacks in standards on some degree .This paper was to analyze the clinical application of PN support in our hospital in order to provide the basis for clinical rational drug use . Methods Random weighting method was applied to collect 5% hospitalized patients′information from each patient unit each month from April 2012 to March 2013 in Nanjing Gerneral Hospital of Nanjing Military Region .NRS-2002 nutrition risk screening was applied to eval-uate whether the patient needed PN support .Statistical analysis were carried out on patients supported with parenteral nutrition from department distribution, PN detailed components and distribution intervals of aII in one admixture non-protein calorie and nitrogen ra-tio. Results According to the survey, 393 patients had received PN support, including 217 cases′NRS score <3 and 176 cases′NRS score ≥3.General surgery department ranked the first in the cases of usingall in oneadmixture support.Among 133 cases receiving all in one admixture support, the course of 37 cases(27.82%) <7 d.The aII in one admixture non-protein calorie and ni-trogen ratio(100~150∶1) only took up 28.57%. Conclusion Although PN has got wide application in clinical departments, the rationality of prescription should be strengthened .Pharmacists should help doctors set up appropriate prescription from the aspect of pharmacy.
