Objective To investigate the therapeutic effect of large dose mucosolvan combined variant flow rate continuous positive airway by nasal mask on neonatal respiratory distress syndrome(NRDS).Methods One hundred and fourteen newborns with NRDS were randomly divided into treatment group(58 cases) and control group(56 cases),on the base of same combined therapy,the cases in control group only underwent oxygen-absorbing by head set with the flow rate 4-6 L/min,and the cases in treatment group were given large dose mucosolvan(Ambroxol Hydrochloride) 30 mg/(kg?d) + 5%GS 20 mL,for two times and variant flow rate continuous positive airway by nasal mask(NCPAP),the parameter setting flow rate 6-8 L/min,FiO_2 0.4-0.6,pressure 5-8 cm H_2O.The clinical symptom and blood gas analysis after 12 and 48 hours were observed and compared the changes of pa(O_2),pa(CO_2),pa(O_2)/FiO_2 in two groups.Results The dyspnea and groan in 44 cases in the treatment group lessoned or vanished,pa(O_2) rised and pa(CO_2) lowered,the oxygenation index obviously increased,the cases with RDS grade Ⅰand gradeⅡ had better therapeutic effect,and the cases with RDS grade Ⅲ(X-ray)and Ⅳ had not manifest effect,the total effective rate was 75.8% in treatment group and 26.7% in control group.There were significant difference in therapeutic effect and oxygenation index between two groups.Conclusions Large dose mucosolvan(combi)-ning variant flow rate continuous positive airway by nasal mask can significantly improve the ventilation and oxygenation function and there are significant therapeutic effect in NRDS,especially in the NRDS grade Ⅰand gradeⅡ,the trachea cannula may be avoided and mechanical ventilation rate may be decreased if the therapeutic method can be used in earlier period.

Objective:To explore the pathogenesis of multiple organ dysfunction syndrome(MODS)with respect to the bal- ance of Th1/Th2.Methods:Eighteen healthy male minipigs,weighing 22-30 kg,were randomly divided into two groups: MODS group and control group.Double-hit method including hemorrhagic shock and endotoxiemia was used to establish the porcine MODS model.The peripheral vein blood samples were collected at different time-points(before bloodletting,before en- dotoxin injection,1 h,24 h,48 h and 72 h after endotoxin injection)in the two groups.The spleen samples were collected after death of the animals.Plasma levels of IFN-?and IL-4 were detected by enzyme-linked immunosorbent assay(ELISA).Real- time PCR was used to detect the expression of IFN-?,IL-4,T-bet and GATA-3 mRNA(The latter 2 were the key transcription factors associated with Th1/Th2 response)in the spleen samples.Results:The plasma levels of IFN-?and IL-4 quickly reached the peak values 1 h after the endotoxin injection,then the level of IFN-?decreased quickly.The ratio of IFN-?/IL-4 was signifi- cantly lower than the baseline value 72 h after endotoxin injection(P=0.000).The ratio of IFN-?/IL-4 mRNA in MODS group was obviously lower than that in the control group(P=0.020);the ratio of T-bet/GATA-3 was also lower in MODS group (P=0.038).Conclusion:The shift from Th1 to Th2 occurs in the progress of MODS.

OBJECTIVEIn order to explore the therapeutic effect of tongxinluo capsule (TXLC) on diabetic nephropathy, the influence on plasma endothelin (ET-1) level of the drug was observed.

METHODSAll the 63 patients enrolled were randomly divided into the treatment group and control group. They were all treated with low protein diabetic diet, oral administration of hypoglycemic or injection of insulin, calcium antagonist according to level of blood pressure and supportive symptomatic treatment. To the treated group, 2 capsules of TXLC were given additionally three times a day. The efficacy was evaluated after 8 weeks' treatment. The chief indices observed before and after treatment were endogenous creatinine clearance rate (CCr), urinary albumin excretion rate (UAER), urinary beta2-microglobulin (beta2-MG), fasting blood-glucose (FBG) and ET-1.

RESULTSBefore treatment, no significant difference was shown in all the tested indices between the treated group and the control group. After treatment, levels of CCr, UAER, beta2-MG, ET-1 and FBG significantly changed in the treated group, showing significant difference as compared with those before treatment (P < 0.05). Moreover, comparison of these indices in the two groups after treatment, excepting FBG, also showed statistical significance (P < 0.01).

CONCLUSIONTXLC shows obvious effect in reducing plasma ET-1 and UAER, it is definitely effective in repairing the renal tubular interstitial damage, and effectively delay the progress of diabetic nephropathy, improve the renal function, and is favorable to ameliorate hyperglycemia auxiliarily.

OBJECTIVETo construct a cDNA library of osteosarcoma SAOS-2 cells and screen the proteins interacting with the bone morphogenetic protein-2 (BMP-2) to explore the role of BMP-2 in the development of prostate cancer.

METHODSThe total RNA was extracted from SAOS-2 cells, from which poly(A)(+)RNA was purified to generate the cDNA using RT-PCR with primer SMARTIII and primer CDSIIIoligo(dT). The library was constructed and screened by cotransformation of the double-stranded cDNA (dscDNA) and linearized pGADT7-Rec with the bait plasmid to the yeast AH109. The proteins interacting with BMP-2 were screened by AH109 mating with the bait strain Y187, and the interaction was confirmed using far-Western blot analysis.

RESULTSThe cDNA library of human osteosarcoma SAOS-2 cells was constructed, which was characterized by high diversity and sufficient capacity. The dscDNA size range was between 250-5000 bp, with a cotransformation efficiency of 4.3 x 10(5) and recombination efficiency of 1.9 x 10(6), and 4.3 x 10(5) clones were screened. The mating efficiency was 32% and 1.0 x 10(6) clones were screened by the bait of BMP-2, and 4 positive clones was obtained and sequenced.

CONCLUSIONThe diversity and capacity of the cDNA library meet the needs for screening genes related to prostate cancer.
