OBJECTIVE:To study the stability of Tramadol hydrochloride,Fentanyl citrate and Ondansetron hydrochloride in-jection in 0.9% Sodium chloride injection. METHODS:At room temperature [(25±1)℃],three injections were poured into infu-sion bag of disposable analgesia pump,and diluted with 0.9% Sodium chloride injection. The changes in precipitation,turbidity, color and pH value of the mixture were observed. The relative percentage of three injections within 72 h were determined by HPLC method. RESULTS:There was no significant change in the pH value and appearance of the mixture. Relative percentage of tramad-ol hydrochloride,fentanyl citrate and ondansetron hydrochloride were all higher than 97% within 72 h. CONCLUSIONS:The mix-ture of Tramadol hydrochloride,Fentanyl citrate and Ondansetron hydrochloride injection in 0.9% Sodium chloride injection keep stable within 72 h under room temperature.

Objective To evaluate the efficacy of aerosol inhalation ofXiyanpingversus ribavirin for the treatment of respiratory tract infections in children.MethodsPubMed, Embase, Cochrane database of Systematic Reviews, CNKI, cqvip and wanfangdata were searched. The randomized controlled trials(RCTs) of aerosol inhalation ofXiyanpingversus ribavirin injections for the treatment of respiratory tract infections in children were incuded. The quality of trials was evaluated and data analyses were performed with the Cochrane Collaboration’s software RevMan 5.0.Results A total of 7 trials were included, involving 857 patients(437 treated withXiyanping, 420 treated with ribavirin). Both of the clinical cure rate(50.11%vs. 40.71%) and clinical effective rate(91.08%vs. 75.95%) in theXiyanping group were significantly higher than those in the ribavirin group, withOR(95%CI) 1.49(1.13 to 1.97) and 3.54(1.87 to 6.71), respectively.Conclusions Aerosol inhalation ofXiyanping superior to aerosol inhalation of ribavirin for the treatment of respiratory tract infections in children. Owing to the poor quality and the small sample size of included trials, more larger good quality CRTs are required to confirm this conclusion.

Objective To explore the application value of ultrasound in the diagnosis and treatment for cesarean scar pregnancy. Method The ultrasonic features, clinical treatment of 42 cases of cesarean scar pregnancy were reviewed retrospectively. Results Among 42 patients,35 patients (83.3% ,35/42) were diagnosed accurately by ultrasound. The sonographic appearance showed 15 cases were gestational sac-type and 22 cases were mixed mass-type,the other 5 cases were classified into type three in which the gestational sac mostly located at the uterine cavity and only the inferior part implanted in the cesarean scar. Uterine artery embolisation and suction curettage with the sonographic guidance with 2 cases, intra-amniotic administration of MTX under sonographic guidance with 15 cases, expectant treatment with 20 cases or complex treatment with 5 cases. During treatment,ultrasonography showed focus of infection was shrinked gradually and blood flow disappeared, blood (3 -human chorionic gonadotrophin was decreased to normal level. ConclusionUltrasound can diagnose cesarean scar pregnancy promptly and accurately, proportionate treatment would be selected according to the type of cesarean scar pregnancy, and also can evaluate the therapeutic effect.

Objective:To explore the clinical effect of negative pressure wound therapy and to discuss the ethi-cal issues in this therapy and seek a solution. Methods:Sixty patients with negative pressure wound therapy in our hospital were invited to participate in this study. Patients were all with deep pressure ulcers or diabetic foot, of which the Wagner Scores were graded as three or four. They were divided into two groups randomly. The subjects in control group received standard treatment, while those in experimental group were treated by self -designed closed negative pressure drainage settings. The wound healing time, the cost of the treatment and comfort were compared between the two groups. Results:The cost of wound care in the experimental group was less than those in the control group (P<0. 001). There was no significant difference in comfort between two groups (P>0. 05). But the wound healing time was longer in the experimental group than those in the control group. Conclusion:Self-designed closed negative pressure settings can decrease the cost of patient care with the equal patient comfort and acceptance as the standard negative pressure, however, the wound healing time has been extended. So before using negative pressure technique, the medical staff should comprehensively analyze, be guided by medical ethics and choose the appropriate treatment for different patients.

OBJECTIVE:To study the general pattern and characteristics of the adverse drug reactions(ADRs) induced by Zhongjiefeng injection for reference of rational drug use.METHODS:A total of 25 ADRs cases induced by Zhongjiefeng injection reported in domestic medical journals during 1994～2007 were analyzed statistically.RESULTS:ADRs of Zhongjiefeng injection were more often seen in children and occurred usually within 30 min after injection,appeared mainly as allergic rcactions (88.0%) or anaphylactic shock in severe cases.CONCLUSION:Clinical physicians and pharmacists should stay on high alert to the ADRs induced by Zhongjiefeng injection and adhere to rational drug use.

Objective To study the expression and clinical significance of serum levels of transforming growth factor-31 (TGF-β1) and tumor necrosis factor-alpha(TNF-α) in patients with hypertensive disorder complicating pregnancy(HDCP).Methods The serum levels of TGF-β1 and TNF-αin 50 cases with HDCP and 30 cases of normal third trimester pregnant women(control group) were detected by ELISA.50 cases with HDCP were divided into gestational hypertension group,mild preeclampsia group and severe preeclampsia group according to the severity of HDCP.Results The serum levels of TGF-β1 and TNF-α in HDCP patients were significantly higher than the control group (t =13.283,13.607,all P ＜ 0.05).The serum levels of TGF-β1 and TNF-α gradually increased with the aggravating of HDCP disease,the serum levels of TGF-β1 and TNF-αwere significantly different among the three subgroups of HDCP(P ＜ 0.05).The correlation analysis showed that the serum levels of TGF-β1,TNF-α were positively correlated with the severity of HDCP (r =0.575,0.512,all P ＜ 0.05),there was significantly positive correlation between the serum TGF-β1 and TNF-α(r =0.515,P ＜0.05).Conclusion The serum levels of TGF-β1 and TNF-α were high in the HDCP patients,the high levels of TGF-β1 and TNF-α can reflect the changes and development of HDCP disease.The abnormal levels of TGF-β1 and TNF-α may be associate with dysfunction of trophoblast cell.

Objective:To analyze the clinical and echocardiographic features of constrictive pericarditis. Methods: Thirty-six patients diagnosed as having constrictive pericarditis from Oct. 1989 to Jun. 2007 were enrolled in this retrospective study. Clinical manifestations and echocardiographic features were analyzed. Results: The main clinical manifestations were fatigue, effort dyspnea(100%), and sign of pressure elevation of vena cava(97%). Echocardiographic features included thickening of pericardium(67%), abnormal motion of septal and posterior wall of left ventricle in diastole(83%,75% respectively), left and right atrial enlargement(92%,39% respectively), early filling changes of mitral flow with respiration(93%), inferior vena cava dilation and without respiration variation(100%), mitral annulus paradoxical enhanced motion in early diastole. Conclusion: Clinical manifestations of pressure elevation of vena cava were indicators for diagnosis of constrictive pericarditis. Echocardiography could be a valuable method for confirming the diagnosis.

Objective To evaluate Left ventricular(LV) diastolic function in essential hypertension by conventional pulse-wave Doppler echocardiography (cPWD) and Doppler tissue imaging (DTI) and compare the two modalities. Methods Two hundred patients with essential hypertension were classified as NLVH subgroup (n = 160) and LVH subgroup (n =40) based on left ventricular mass index (LVMI) with one hundred and sixty health subjects as control group. The mitral valve flow pattern (MVFP) was obtained.Early diastolic (E) and late velocities (A) were measured and E/A was calculated. DTI was used to obtain the left ventricular lateral wall early diastolic mitral annulus velocity (Em) and E/Em was calculated.Results Essential hypertension patients had LV diastolic dysfunction both by cPWD (higher E and lower E/A ratio) and DTI (lower Em and higher E/Em ratio) compared with healthy subjects [E:(0. 88 ±0. 18)cm/s vs (0. 76 ±0. 19) cm/s;E/A ratio:0. 86 ±0. 28 vs 1.02 ±0. 38;Em: (9. 4 ±2. 8)cm/s vs (11. 9 ±3. 8)cm/s;E/Em ratio;7. 9 ± 2. 7 vs 6. 0 ± 1. 8: with all P value ＜0.01]. Em was significantly reduced and E/Em was significantly elevated in LVH subgroup than NLVH subgroup [Em; (7.7 ±2. 6) cm/s vs (9. 9 ± 2. 8) cm/s, E/Em: 9. 6 ± 3. 6 vs 7. 4 ± 2. 4, P ＜ 0. 05]. No significant difference was found in A and E/A between these two subgroups [(0. 90 ± 0. 22) cm/s vs (0. 87 ± 0. 17) cm/s; 0. 80 ± 0. 34 vs 0.88 ±0.28, P ＞ 0.05]. Conclusions cPWD and DTI both had implications to detect diastolic dysfunction in non-hypertrophic stage hypertension. Em、E/Em could be more sensitive and precise to reflect the impairment of diastolic function in the progress of hypertension.
