Objective To study the clinical therapeutic effect of arthroscopic debridement cooperated with injecting chuanxiongqin in treating knee osteoarthritis. Methods Sixty cases of knee osteoarthritis were randomly divided into 2 groups: treating group and control group, 30 cases in each group. The treating group were treated by arthroscopic debridement cooperated with injecting chuanxiongqin;the control group were given hyaluronate-Na after received arthroscopic debridement. The operation evaluation criteria of JOA was taken to value the therapeutic effect at 1 week, 3 months, 6 months and 12 months postoperation. At the same time, nitric oxide (NO) content in joint fluid were measured at preoperation, 1 week, 4 weeks, 3 months postoperation. Results At 1 week postoperation, there were no statistically significant differenced > 0.05) between the two groups,at 3, 6 and 12 months postoperation, the therapeutic effect of the treating group were much better than those of the control group (P < 0.01);NO content in joint fluid of preoperative treatment group [(90.32 ± 22.24) μmol/L]and control group [(90.31 ±22.20) μ mol/L]was similar, there was no significant difference (P >0.05). At 3 months postoperation, NO content in joint fluid of the treating group [(85.63 ± 30.63) μ mol/L]decreased significantly compared with preoperative (P < 0.05 ) , and the content was much lower than that of the control group [(89.66 ± 20.63 ) μ mol/L], there was significant difference between the two groups (P < 0.05). Although NO content in joint fluid of the control group was decreased, but the difference was not statistically significant (P >0.05). Conclusions Arthroscopic debridement with injecting chuanxiongqin in treating knee osteoarthritis can control inflammatory reaction of cartilage and synovia]in effect, improve the therapeutic effect. Therefore, it should be avalid method in treating knee osteoarthritis.

Objective To investigate the efficacy and safety of different doses of dezocine at different administration time on analgesia after laparoscopic cholecystectomy.Methods 80 patients elected from ASA Ⅰ-Ⅱ grade laparoscopic cholecystectomy were randomly divided into four groups,20 cases in each group.Group Ⅰ was anesthetized by intravenously injected dezocine 0.10mg/kg before the surgery,group Ⅱ was anesthetized by dezocine 0.15mg/kg before the surgery,group Ⅲ was anesthetized by intravenously injected dezocine 0.10mg/kg after stopping anesthetic surgery,and group Ⅳ was anesthetized by intravenously injected dezocine 0.15mg/kg after stopping anesthetic surgery.The postoperative pain scores were observed 1,6,12,24 hours after operation in the four groups by using visual analog scale (VAS),comfort score (BCS),and anesthesia recovery score (modified Aldrete score).Results TheVAS of the four groups 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.308,P =0.036),group Ⅰ and group Ⅳ was significantly different (t =2.106,P =0.042),group Ⅱ and group Ⅲ was significantly different (t =2.711,P =0.014),group Ⅱ and group Ⅳ was significantly different (t =2.317,P =0.037).The BCS 1 hour after surgery:group Ⅰ and group Ⅲ was significantly different(t =2.108,P =0.042),group Ⅰ and group Ⅳ was significantly different(t =2.069,P =0.048),group Ⅱ and group Ⅲ was significantly different (t =2.353,P =0.033),group Ⅱ and group Ⅳ was significantly different (t =2.361,P =0.036).The VAS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.084,P =0.045),group Ⅱ and group Ⅲ was significantly different(t =2.309,P =0.038),group Ⅱ and group Ⅳ was significantly different(t =2.303,P =0.040).The BCS 6 hours after surgery:group Ⅰ and group Ⅲ was significantly different (t =2.294,P =0.041),group Ⅱ and group Ⅲ was significantly different(t =2.322,P =0.035),group Ⅱ and group Ⅳ was significantly different (t =2.070,P =0.048).The BCS 12 hours after surgery:group Ⅱ and group Ⅲ was significantly different(t =2.518,P =0.047).VAS and BCS scores at other time points had no significant difference (P ＞ 0.05).Conclusion The analgesic after laparoscopic gallbladder surgery using dezocine 0.10mg/kg-0.15mg/kg,especially 0.15mg/kg administered anesthesia before surgery,can effectively relieve postoperative pain and improve postoperative comfort,reduce postoperative analgesic(pain pump) and has less adverse reactions,which is worthy of promotion.

BACKGROUND:Brain natriuretic peptide, an important serum marker for diagnosis of cardiovascular diseases, is crucial for risk factor analysis of cardiovascular diseases.
OBJECTIVE: To analyze the relationship between brain natriuretic peptide and hemodynamic parameters before and after coronary artery bypass grafting.
METHODS:Thirty patients with coronary heart disease undergoing coronary artery bypass grafting were selected, including 13 patients with left ventricular ejection fraction≥ 50% (normal heart function) and 17 patients with left ventricular ejection fraction < 50% (cardiac insufficiency). Levels of plasma brain natriuretic peptides were detected at 1 day before transplantation, 7 hours, 1, 3, 5, 7 days after transplantation, and then the correlation between plasma brain natriuretic peptide levels and hemodynamic parameters was analyzed before and after coronary artery bypass grafting.
RESULTS AND CONCLUSION: Preoperative and postoperative levels of plasma brain natriuretic peptides were significantly lower in the patients with left ventricular ejection fraction≥ 50% than those with left ventricular ejection fraction < 50%; while in each group, the level of brain natriuretic peptides was remarkably increased after coronary artery bypass grafting (P < 0.05 orP< 0.001). Preoperative brain natriuretic peptide levels were positively correlated with New York Heart Association classification grading, left atrial diameter and left ventricular diameter (r=0.61;r=0.34;r=0.67), but negatively correlated with echocardiographic left ventricular ejection fraction and cardiac output (r=-0.75;r=-0.70). The postoperative peak level of brain natriuretic peptides was positively correlated with New York Heart Association classification grading, echocardiographic left ventricular end diastolic diameter and pulmonary artery pressure (r=0.72;r=0.70;r=0.45). These findings indicate that the plasma level of brain natriuretic peptides before coronary artery bypass grafting shows a good correlation with left ventricular ejection fraction and left ventricular end diastolic diameter, which accurately reflect the state of cardiac function before coronary artery bypass grafting.

OBJECTIVE:To investigate clinical efficacy and safety of Miao medicine Jinyin huashi granules combined with western medicine in the treatment of chronic calculous cholecystitis(CCC). METHODS:A total of 120 CCC patients in our hospi-tal during Jan. 2014-Jan. 2016 were randomly divided into control group and observation group,with 60 cases in each group. Con-trol group was given 50％ Magnesium sulfate solution 10 mL orally before meal,tid;amoxicillin 0.5 g orally,tid+Racanisodamine tablets 10 mg,tid+Compound dantong tablets 1 slice,tid,after meal. Observation group was additionally treated with Miao medi-cine Jinyin huashi granules 15 g,tid,on the basis of control group. Both groups were treated for consecutive 4 weeks. Clinical effi-cacies,the improvement of upper abdominal pain,nausea and greasy,calculus were observed in 2 groups. The thickness of gall-bladder,serum levels of IL-2 and IL-5,mRNA and protein expression of CYP7A1 and B-UCT were compared between 2 groups before and after treatment. The occurrence of ADR was recorded in 2 groups. RESULTS:Total response rate of observation group was 96.67％,which was significantly higher than 88.33％ of control group,with statistical significance (P<0.05). One d and one week after treatment,the improvement rates of upper abdominal pain were 63.33％ and 81.67％ in observation group, which were significantly than 36.67％ and 50.00％ of control group,with statistical significance(P<0.05). There was no statisti-cal significance in the improvement rate of nausea or greasy after treatment between 2 groups(P>0.05). The stone-free rate of ob-servation group was 33.33％ and significantly higher than 11.67％ of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the thickness of gallbladder wall,serum levels of IL-2 or IL-15,mRNA and pro-tein expression of CYP7A1 or B-UCT between 2 groups(P>0.05). After treatment,the thickness of gallbladder wall,serum lev-els of IL-2 and IL-15 were all decreased significantly in 2 groups,while mRNA and protein expression of CYP7A1 and B-UCT were increased significantly;observation group was significantly better than control group,with statistical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05).
