Objective To investigate effects of zingiber alcohol extract(ZGB)on the inflammation-associated cytokines in rats with carbon tetrachloride(CCL4)induced hepatic fibrosis.Methods 24 adult male SD rats were randomly divided into three groups:normal control group(CON,n=8),hepatic fibrosis model group(HF,n=8),and zingiber administration group(ZGB,n=8).The rats in the HF and ZGB groups were administrated by subcutaneous injection of 50%CCL4 3 mL/kg,twice per week for 8 weeks,the first time dosage was doubled.At the same time the ZGB group received daily intragastric ZGB(300 mg/kg a day),while the CON and HF groups received daily intragastric isovolumic normal saline for 8 weeks.The animals were executed at the end of 8 weeks.Serum samples were collected for detecting the content of ALT,AST.The liver samples were used for assessing the Hyp content,detectingα-SMA level by Western blotting and TNFα,IL-1 b,IL-6 mRNA levels by the real-time PCR.The histological ob-servation of the liver tissue was done with HE stain.Results As compared with the HF group,the serum levels of ALT and AST in the ZGB group were markedly decreased,and the content of Hyp in liver tissue was decreased(P<0.05).The Western blot re-sults showed that the expression amount ofα-SMA protein in the ZGB group was significantly lower than that in the HF group(P<0.05);the real-time quatitative PCR showed that the expression levels of TNFα,IL-1b,IL-6 were decreased compared with the HF group(P<0.05).The hepatocyte degeneration degrees observed by the optical microscope in the ZGB group were significantly alle-viated compared with the HF group.Conclusion ZGB has better anti-hepatic fibrosis and hepatocyte-protective effect,one of its mechanisms could be that ZGB could reduce the release of pro-inflammatory cytokines TNFα,IL-1b and IL-6,thus delay or hinder the progress course of liver fibrosis.

OBJECTIVE:To study the volatile constituents of the compound extract from Folium Perillae,Pericarpium Citri and Herb Schizonepetae in Siji Ganmao tablet by supercritical CO2 fluid extraction (SFE-CO2). METHODS:Supercritical CO2 ex-traction technology was used to extract the volatile constituents of 3 medical material in Siji Ganmao tablet. The chemical constitu-ents of the compound extract from 3 medicinal materials were analyzed by GC-MS. RESULTS:The extracting rate of SFE-CO2 was 2.21%,21 compounds in the compound extract were separated and 16 compounds were identified with the major components of si-nensetin(36.56%)and linolic acid(19.52%). The extracting rate of water steam distillation(SD)was 1.035%,51 compounds in the compound extract were separated and 32 compounds were identified with the major components of D-limonene(62.40%) and thujone(15.49%). CONCLUSIONS:The volatile constituents of F. perillae,P. cCitri and H. Schizonepetae can be compound ex-tracted by SFE-CO2,however,it is different from the constituents of the compound volatile oil by SD.

Objective To observe the effect of the combined therapy on headache after craniotomy.Methods 30 patients complained severe headache after craniotomy were divided into the treatment group (n=15, received the combined therapy mainly including nerve block) and control group (n=15, received professional medicine). The visual analogue scale (VAS), admission days after surgery, and medical fees of the patients in two groups were compared.Results The VAS scores of the patients in the treatment group decreased significantly after treatment ( P<0.01), the admission days after surgery significantly shortened ( P<0.01), and the fees of examination, medicine, and ward bed significantly decreased compared with the control group.Conclusion The combined therapy mainly including nerve block is effective on headache after craniotomy.

Objective To explore the feasibility of the double venipuncture instead of central venous catheter as a temporary vascular access in hemodialysis.Methods The upper arm below the 1/3 was tied a tourniquet,and fistula needle directly punctured the vein in the middle of the elbow.After the success of the puncture,elastic bandage was replaced by a tourniquet,and the ball movement was done by imitating the blood donation member for blood donation at hand gripping a ball or elements as the artery blood lead.Another elbow vein or lower limb saphenous vein was punctured.Thirty patients using double venipuncture dialysis or central venous catheter dialysis 2 weeks or more were randomly selected into each group,and biochemical and renal function was measured before dialysis.Results All of 1 282 patients who were newly into the blood dialysis,mature arteriovenous fistula was in 8 patients (0.6％,8/1 282),deep venipuncture to insert the central venous catheter was in 542 patients(42.3％,542/1 282),using the double venipuncture was in 732 patients (57.1％,732/1 282).The flow of blood was 180-200 ml/min,the avalible time was 1-2 months.The serum creatinine,blood urea nitrogen,calcium,phosphorus and carbon dioxide combining power had no significant difference between two groups (P ＞ 0.05).Conclusions The majority of patients with double venipuncture blood flow can satisfy the need of dialysis.Because the operation is simple,no recycling and may reduce the deep venipuncture,it is an ideal temporary vascular access.

Objective To understand teicoplanin concentration in cerebrospinal fluid (CSF)during intravenous in-fusion in patients following neurosurgery operation,and evaluate whether drug concentration can be increased if blood-brain barrier was damaged, and effect of continuous pump of drug on drug concentration in CSF. Methods The post-neurosurgical surgery patients with surgical site/ventricular drainage were enrolled in the study, patients were divided into routine administration group(a dose of teicoplanin of 400 mg/12 h was administered for 30 min)and continuous administration group (a dose of 400 mg teicoplanin was administered for 30 min followed by a continuous infusion of 200 mg/6 h).CSF specimens were collected at respective time points of administration, teicoplanin concentration in specimens was measured.Results For routine administration group,drug concentration in CSF was (0.004 ± 0.0123 )mg/L immediately after teicoplanin was bumped,the peak concentration was (0.712 ± 1.028)mg/L after 1-hour bumping,then concentration decreased gradually,which were (0.254 ±0.222),(0.173 ± 0.152),and (0.355±0.207)mg/L at 12,18,and 24 hours of bumping respectively.For continuous administration group, drug concentration in CSF was(0.017±0.020))mg/L immediately after teicoplanin was bumped,the peak concentration reached (0.587±0.255)mg/L after 4-hour bumping,then concentration were (0.429±0.416),(0.325±0.254),(0.476 ±0.686),and (0.318 ±0.464)mg/L at 6,12,18,and 24 hours of bumping respectively,teicoplanin concentration was relatively stable 6 hours later,which were (0.318±0.464)mg/L-(0.476±0.686)mg/L.The area under the curve during 24 hours (AUC0-24 )in routine administration group and continuous administration group were 5.590 mg/L·h and 9.082 mg/L·h respectively.For two groups of patients,teicoplanin concentration only at the area near peak value a-chieved 50% minimum inhibitory concentration(MIC50 )for coagulase negative staphylococcus (CNS),but the time for a-chieving concentration higher than CNS MIC50 was far less than 50% of total administration time;teicoplanin concentration in CSF of both groups of patients didn’t achieve MIC50 for Staphylococcus aureus .Conclusion After continuous infusion of teicoplanin,drug concentration in CSF can be increased compared with routine administration group,but still can’t achieve the effective MIC;the increase of blood drug concentration is benefit to drug concentration in CSF,it is necessary to in-crease the dose appropriately to achieve clinical effectiveness.

Objective To evaluate the impact factors on weight and proportion of prostate tissue resected by transurethral resection of prostate (TURP) in patients with benign prostatic hyperplasia (BPH). Methods The patients undergoing TURP from January 2007 to June 2009 and diagnosed as BPH according to postoperative pathological results were enrolled in this study. The prostate volume measured by transrectal ultrasound (TRUS), prostate specific antigen (PSA), maximum flow rate (MFR), residual urine volume and body mass index (BMI) were measured and calculated. The prostate tissue collected at resection was weighed, and the proportion of the prostate resected was the percentage of the pre-operative estimated weight. Results For the 458 patients with the average age of 69.5 years, average BMI was 24. 3 kg/m2 , PSA 6. 1 μg/ml, prostate volume 85.5 ml, MFR 8. 4ml/s, residual urine volume 31.8 ml, resected prostate weight 32.9 g, proportion of resection 37. 6%Prostate volume and BMI were positively related with resected prostate weight. BMI was positively related with proportion of prostate resection. There was no linear correlation between prostate volume and resected proportion. But there was significant difference in resected proportion between patients with prostate volume more than and less than 40 ml. Finasteride had no influence on the weight and resected proportion. Conclusions Prostate volume, PSA and BMI are correlated with weight and proportion of prostate tissue resected by TURP. Finasteride has no influence on the resected weight and proportion.
