Objective To explore the clinical significance of hydrogen sulfide(H2S)and heme oxygenase-1(HO-1)on pulmonary hypertension(PH),by detecting their levels of patients with congenital heart disease(CHD).Methods Forty-eight patients with CHD who had left-to-right shunt were selected randomly from cardiac surgery in the Fourth Hospital of Hebei Medical University.Forty-eight patients were performed successfully on radical operation under complex intravenous anesthesia,and they were divided 3 groups according to pulmonary artery systolic pressure(PASP)detected by doppler echocardiography before operation:no PH group(PASP0.05).Conclusions H2S plays an important role in the formation of PH and restructure.There is no correlation between PASP and HO-1 activities in serum,but HO-1 may be play an indirect action in the formation of PH and restructure.Measuring the levels of H2S may be a reliable method to follow the change of pulmonary pressure and worsening of PH.

?AIM:To explore the efficacy and safety of operation in treating secondary glaucoma caused by contusion hyphema.?METHODS: Seventy patients (70 eyes) with secondary glaucoma caused by contusion of anterior chamber in our hospital from November 2014 to November 2015 were selected.All patients were treated by operation.Visual acuity, anterior chamber depth, mean intraocular pressure and postoperative complications of patients before and after operation were compared.?RESULTS:Patients with secondary glaucoma caused by contusion of anterior chamber had better visual acuity after operation and the difference was statistically significant (t=42.471, P<0.001).And they had deeper anterior chamber depth and lower mean intraocular pressure, and the differences were statistically significant (t=9.726, 26.041; P<0.001).Two of those patients had emergence of hyphema after operation and symptomatic relieved after treatment. None of the patients had complications such as blood-staining of cornea or eye pain.? CONCLUSION: The curative effect of operation in treating secondary glaucoma caused by contusion of anterior chamber is good and safe and it can improve visual acuity, deepen the anterior chamber angle depth and reduce the intraocular pressure.

Separation of complex mixtures needs more resolving power. In two dimensional liquid chromatography (2D LC), the sample is subjected to two different separation conditions or mechanisms, which significantly increases the peak capacity,resolving power and reduces peak overlap. Meanwhile, 2D separation is more reliable for peak i-dentification from run to run than single-dimension chromatography, because two independent elution times are ob-tained for each peak. Among different 2D liquid chromatographic combinations/configurations, online comprehensive 2D-LC has appeared to be very attractive due to its high peak capacity, minimal sample loss, good reproducibility, and easy to automation, especially for separation of very complex samples. The present review discusses the theoreti-cal aspects and hardware configuration of online 2D-LC, particularly online comprehensive 2D-LC. It highlights its concept, features, advantages, applications and prospective in TCM quality Control analysis.

Objective To analyze the application of color Doppler ultrasonography in diagnosis of diabetic carotid sclerosis and to study the relation between diabetes and carotid sclerosis. Methods Color Doppler ultrasound findings in 68 hospitalized type 2 diabetes patients ( as an observation group) and in 73 healthy individuals ( as a control group) were compared and analyzed from Feb. 2007 to Feb. 2009. Results The tunica intima and media of carotid were significantly thicker in observation group than in control group ( P

Encephalopathy of prematurity is still an important reason which affects the survival and quality of life of preterm infants. During hospitalized in neonatal intensive care unit(NICU),a variety of environmental factors such as noise,light,too much tactile stimuli,pain,and maternal - infant separation all will affect the development of preterm infants' brain,leading to encephalopathy of prematurity. Therefore,need to attach importance to the effects of NICU environment on the growth and development and the neurological function of preterm infants,try to optimize the environment of NICU,to reduce the incidence of brain injury of prematurity,improve the long - term prognosis of pre-term infants.

Tumor recurrence is the main factor affecting the postoperative prognosis of hepatocellular carcinoma.The forecast of tumor recurrence by monitoring biomarker can effectively improve the prognosis of such disease.To improve the detection rate of early cancer recurrence can be achieved by detecting the level of the alpha-fetoprotein (AFP),Lens culinaris agglutinin-reactive fraction of AFP (AFP-L3),des-γ-carboxyprothrombin (DCP),or combined detection.In recent years,the researches on the miRNA and Long Noncoding RNAs (LncRNA),which are key regulators in the upstream of signal pathways,could provide a new way for HCC recurrence monitoring.The combined detection of biomarkers in different control levels,maybe is the effective measure to improve the tumor recurrence detection rate,and is also the focus of the further research.

Objective To study the efficacy of sodium profile combined with ultrafiltration profile in preventing intradialytic hypotension and changes of the sodium level in blood plasma after hemodialysis. Methods 10 patients with maintenance hemodialysis were chosen randomly. Every patient underwent with conventional hemodialysis treatment and sodium profile combined with ultrafiltration profile treatment 5 times alternatively. And then the blood pressure changes. HR changes, ultrafiltration volume changes and clinical symptoms were observed during treatments. And also after HD, the sodium level in blood plasma was observed. Results The blood pressure decrease of sodium profile combined with ultrafiltration profile evidently reduced the conventional HD treatments( P＜0.01 ).Ultrafiltration volume of the former evidently increased compared with that of the latter(P＜0.01 ). The sodium level in blood plasma after HD was not significantly changed compared with before HD(P＞0.05). Conclnsion Sodium profile combined with ultrafiltration profile diminishes the episodes of hypotension evidently and increases the ability to endure sufferirgs to patients and does not increase the sodium level in blood plasma. So it is an effective medical treatment.

Objective To observe the effectiveness and salty of Xiaoer Dingfeng Decoction(Decoction to stop wind in children con- vulsion)in the treatment of syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.Methods Totally 90 infantile patients were randomized into three groups,which were treated by Xiaoer Dingfeng Decoction,Kangxian(Capsule to treat epilepsy)and Xifeng Capsule(Capsule to calm the wind)respectively.Frequency of seizure,lasting duration,and change of electroen- cephalogram(EEG)were observed 12 months later.Results The total effective rate of Xiaoer Dingfeng Decoction group was 86. 67%,better that that of Kangxian Capsule group(P0.05). It could greatly reduce the frequency of seizure,shorten the lasting duration,and improve the EEG.Conclusion Xiaoer Dingfeng De- coctions is effective and safe for the syndrome of primary infantile convulsion due to phlegm-heat in tonic-clonic epilepsy.

OBJECTIVETo preliminarily study the effective dosage range and mechanism of the abirritation of volatile oil of Evodia Fructus on the stomach cold syndrome model in mice, and discuss the correlation between its accompanying toxicity and oxidative damage mechanism, in order to provide the experimental basis for explaining the efficacy-syndrome-toxicity correlation.

METHODThe stomach cold-syndrome model in mice was induced by the classic hot plate test by orally administrating with different doses of volatile oil of Evodia Fructus, in order to observe its abirritation and companying toxic and side effects and detect serum ALT, AST, PGE2, NO, NOS, MDA, SOD, GSH, GSH-Px, BUN, CR and hepatic ALT, AST. The companying toxic symptoms in mice were recorded in toxic reaction integral table.

RESULTVolatile oil of Evodia Fructus had an obvious analgesic effect at 30 min after the oral administration and reached the peak effect at 60 min, with certain "dose-effect" and "time-effect" relations, rises in serum and hepatic ALT and AST levels, serum PGE2, MDA, NO and NOS and hepatic indexes, decreases in SOD, GSH and GSH-Px and no notable change in BUN, CR levels and kidney weight/body ratio. Conclusion: The abirritation mechanism of volatile oil of Evodia Fructus was related to the inhibition of pain transmitter release, peroxidative damage and NO damage, which is accompanied by certain hepatotoxicity, mainly mainly oxidative damage, with a concurrent "dose-time-toxicity" relationship.
