Objective:To investigate the culture technique and secretory function of parathyroid cells in rats in order to establish experimental basis of parathyroid cell transplantation.Methods:After parathyroid glands were digested by collagenase and trypsin,isolated parathyroid cells were cultured.The cells cultured for 5 days were observed by transmission electron microscopy.Parathyroid hormone obtained from the cell culture fluid on day 1,3,5 and 7 was measured respectively.Results:Parathyroid cells cultured for 5 days had abundant rough surfaced endoplasmic reticula、Golgi bodies、stab mitochondria and secretory granules.Cultured parathyroid cells could secrete parathyroid hormone normally,especially on the 5th day.Conclusion:Parathyroid cells cultured for 5 days still possess original morphologic structure and have maximum secreting function,so it is an optimal donor for transplantation.

OBJECTIVE: To evaluate the efficacy and safety of diammonium glycyrrhizinate in the treatment of drug-induced liver injury according to present clinical studies. METHODS: Retrieved from CBM and the CNKI from 1994 to 2009, literatures about the randomized controlled trials that the effective rate of diammonium glycyrrhizinate was compared with that of other hepatoprotective with drug-induced liver injury and drug-induced liver disease as study subjects. RESULTS: 18 RCTs including 1,644 patients with drug-induced liver injury were enrolled. The effective rate of diammonium glycyrrhizinate group was higher than that of control group, statistical significance was noted in two groups (P

Objective To explore the main affecting factors on sanitary quality of public places and to assess the sanitary quality scientifically. Methods The sanitary qualities of 6 kinds of public places of entertainment in Taiyuan during 1998～2000 were assessed using the method of compreheusive fuzzy assessmeat. Results All of 6 kinds of public places revealed similar sanitary qualities. All of the sanitary indexes accorded with the related National Sanitary Standards. The sanitary qualities were better for ballrooms, theaters, bar and billiard rooms in hotels with Grade Ⅰ quality, and were worse for tennis and bowling halls with Grade Ⅱ quality. The assessments on single index showed that the affecting factors of sanitary quality of public places of entertainment were the levels of CO2, noise and CO. Conclusion The sanitary quality of entertainment public places was better during 1998～2000.

Only in recent years, attentions have been drawn to the significance of expressing killer cell inhibitory receptors (KIR) in T cells KIRs specifically bind to the corresponding region of the MHC class I molecules and transmit negative signals to prevent cytotoxity of T cells. When the ligands of KIRs are missing, the lysis of the target cells can't be avoided. Perhaps the existence of KIRs is the main mechanism for preventing T cells from attacking autologous tissues. The recognition mechanism of the interaction between the KIR + donor T cells and the recipient's MHC class I molecule expressing tissue cells might shed light on the establishment of the immunotolerance for the prevention of allo-graft rejection and graft-versus-host disease.

Malnutrition is the common complication for the patients with gastrointestinal neoplasms during perioperative period.Tumor and chemotherapy drugs are the main influencing factors of patients with malnutrition.The correct evaluation of the nutritional status in patients is the basis of individualized nutrition therapy.New evaluation methods and nutritional preparations could more help patients with gastrointestinal neoplasms during perioperative period to maintaining good nutritional status.

AIM To study the effects of cyclophosphamide (CTX) on the pharmacokinetics of buthionine sulfoximine (BSO)in Walker 256 tumor bearing rats. METHODS Walker 256 tumor bearing rats were treated ip for 4 days with saline or CTX in saline (20 mg?kg -1 ), then received iv BSO 200 mg?kg -1 . BSO concentration in rat plasma was determined by a reverse phase HPLC with fluorescence detection after precolumn derivatization with o phthaldialdehyde. Compartment model and pharmacokinetic parameters were determined by 3P87 software processed on a computer. RESULTS A single intravenous dose of BSO 200 mg?kg -1 was eliminated from plasma in a two compartment manner in tumor bearing rats. The pharmacokinetic parameters of BSO were as follows: In tumor bearing control rats, T 1/2? =(11 1?2 4) min, T 1/2? =(65?14) min, CLs=(12 8?1 3) ml?min -1 ?kg -1 , AUC=(262?26) mg?L -1 ?h; in tumor bearing CTX treated rats, T 1/2? =(8 2?1 8) min, T 1/2? =(42?3) min, CLs=(13 4?1 9) ml?min -1 ?kg -1 ,AUC=(252?35) mg ?L -1 ?h. CONCLUSION There is no significant difference between the parameters of tumor bearing control and CTX treated rats except T 1/2? .

Drug induced liver injury(DILI) is one of the most common factors causing liver damage and liver failure in children.And in most cases,patients' manifestations lack characteristic features.Thus,patients will develop gastrointestinal symptoms such as jaundice,nausea,vomiting and abdominal abstention until serious hepatic dysfunction.Futhermore,some patients are likely to develop acute liver failure,even death,without drug discontinuation and timely intervening measures.Early diagnosis and effective therapies considerably make sense.This review aims to illustrate the mechanism,manifestations,diagnosis and treatment of DILI in children,in order to promote the early treatment of the disease,reduce the serious complications and improve survival rate in clinical work.

OBJECTIVE:To establish an HPLC method for the determination of gastrodin in Choudongning capsule. METHODS:The sample was determined on Elite C18 column(250 mm?4.6 mm,5 ?m);the mobile phase consisted of methanol -water(3∶97) at a flow rate of 1.0 mL?min-1;the detection wavelength was set at 221 nm. RESULTS:The linear range of gastrodin was from 0.051 ?g to 0.357 ?g(r=0.999 9) and its average recovery was 98.99%(RSD=1.91%,n=6).CONCL-USION:The method is convenient,accurate and reproducible,and it is applicable for the quality control of Choudongning capsule.

OBJECTIVE:To improve the quality of drug consultation.METHODS:The drug consultation records of a total of 1 663 cases in our hospital from July 2004 to July 2007 were analyzed statistically by a retrospective method.RESULTS:Of the drug consultation records of a total of 1 663 cases,the chief questions consulted were adverse drug reactions and long-term medication safety(25.2%),dosage and administration(21.1%),medication for special populations(9.7%),drug interactions(8.1%),pharmacological action and indications(7.1%),and generic name and composition of drugs(5.2%).CONCLUSION:The drug consultation service in our hospital achieved a remarkable efficacy in guiding physicians and pharmacists on rational drug use;however,it has its problems and remains to be improved further.
