OBJECTIVE:To observe the clinical efficacy and safety of ambroxol hydrochloride in the treatment of neonatal re-spiratory distress syndrome. METHODS:108 cases of neonatal respiratory distress syndrome were randomly divided into control group and observation group,54 cases in each group. Control group were treated with conventional treatment,such as oxygen inha-lation,anti-infection and nutritional support,observation group was additionally treated with 30 mg/kg Ambroxol hydrochloride in-jection,ivgtt,qd,for continuous treatment of 4-6 d. Clinical efficacy,blood gas indexes [oxygen partial pressure(PaO2),carbon dioxide partial pressure (PaCO2)],12,24 and 48 h after treatment remission time of clinical symptoms,hospitalization time, changes of X-ray film value,tidal volume(VT)and dynamic lung compliance(Cdyn)in 2 groups were compared,and the inci-dence of adverse reactions was observed. RESULTS:The total effective rate in observation group was 94.44%,which was signifi-cantly higher than control group (51.58%),the difference was statistically significant (P<0.05);there was no significant differ-ence in the blood gas indexes in observation group after 12 h(P>0.05),PaO2 was significantly higher than control group and Pa-CO2 was significantly lower than control group 24 and 48 h after treatment,there was significant difference between 2 groups(P<0.05). Remission time of cyanosis,dyspnea,lung moist rales and hospitalization time in observation group were shorter than con-trol group,the difference was statistically significant(P<0.05). X-ray film value,Cdyn and VT levels in observation group were significantly higher than control group,the difference was statistically significant(P<0.05). The incidence of adverse reactions in observation group was 3.70%,which was significantly lower than control group(18.52%),the difference was statistically signifi-cant(P<0.05). CONCLUSIONS:Ambroxol hydrochloride shows obvious efficacy in the treatment of neonatal respiratory distress syndrome,it can improve blood gas indexes and accelerate the recovery from disease,with good safety.

Objective To study the effects of angiogenesis inhibitor SU5416 on the growth and metastasis of pancreatic cancer in SD rat model. Methods Dimethylbenzanthracine (9 mg) (DMBA),was implanted into the parenchyma of Sprague Dawley rat pancreas to induce pancreatic cancer. Rats with established pancreatic carcinoma were randomly divided into 4 groups (15 rats each) to receive every the other day for consecutive 13 weeks before sacrifice peritoneal cavity injection of: Normal saline (control),5-fluorouracil 30 mg?kg -1 (5-Fu group),SU5416 16 mg?kg -1 (SU5416 group),and both 5-Fu and SU5416(combined treatment group). Tumor weight,inhibition rates,intratumoral microvessel density (MVD),apoptotic index (AI) and metastasis were evaluated. Results Tumor weight was (1.15?0.21) g,(0.68?0.42) g,(0.31?0.11) g,(0.19?0.06) g respectively;the inhibition rate was 0,48%,80%,85% respectively;the intratumoral microvessel density (MVD) was (12.3?3.2),(11.4?3.8),(2.1?1.5),(1.8?1.1) respectively;The apoptotic index (AI) was (2.64?1.86)%,(5.71?3.14)%,(13.21?4.26)%,(21.12?7.15)% respectively.
