RESULTS: The anterior ocular media of early postoperative became transparent quickly. No exudative lemma and no complications were found relate to puncture incisions after operations.
CONCLUSION:23G minimally invasive vitreous cutting system can be used in the first stage of anterior segment reconstruction on sever ocular injury. It can reduce iatrogenic injury, operative complications and inflammatory response, also can shorten therapeutic time and create favorable conditions.

Objective To evaluate the effect of one-visit endodontic treatment for infected root canals with combination of nickel-titanium instruments and ultrasonic technique and warm vertical technique.Methods According to treatment,90 teeth were randomly divided into experimental and control groups.Two groups were used nickel titarlium root canal preparation.Experimental group:51 teeth for ultrasonic root canal irrigation,and warm vertical technique was employed to fill the root canal.Control group:39 teeth for rinse syringes,and warm vertical technique was employed to fill the root canal.Washing fluid was 2％ sodium hypochlorite.The root canal filling was observed after a week and one year of postoperative pain response.Results A week later,two groups of post-operative pain showed that there was significant difference in responses (x2 =15.525,P ＜ 0.05).One year later,the two groups showed no significant difference in efficacy(x2 =0.085,P ＞ 0.05).Conclusion The combination of nickel-titanium instruments and ultrasonic irrigation technique and warm vertical obturation,for the treatment of infected root canals was a method to complete the root canal filling,could reduce both the number of patients subsquent visits and the postoperative pain response,while it could improve the quality of root canal filling.

Objective To explore the effects of mechanical ventilation on the treatment of acute severe left heart failure.Methods While the routine drug therapy was used,25 patients with severe acute left heart failure received mechanical ventilation treatment.The changes of their artery blood gas,vital signs and clinical symptom were observed before and after mechanical ventilation.Results The parameters of their blood gas and clinical symptom were dramatically improved after the mechanical ventilation therapy in 21 patients(P＜0.01).19 patients were saved successfully and 6 patients died.Conclusion The mechanical ventilation could effectively improve the clinical symptoms and respiratory function of patients with acute severe left heart failure,which is an effective method in the adjuvant treatment of patients with acute severe left heart failure.

The origin and development of umbilical therapy in traditional Chinese medicine is explored from related literature in the history. As a result, the Shang period is regarded as initial period of umbilical therapy, while periods from Han Dynasty, Jin Dynasty and Southern-Northern Dynasties to Sui Dynasty and Tang Dynasty could be taken as stage of primary development. Time from Song Dynasty, Jin Dynasty and Yuan Dynasty to Ming and Qing Dynasties is believed as mature stage. Also the manipulation, application principle, indications and contraindications of umbilical therapy are explained. A brief overview of modern development of umbilical therapy is also described.

Objective To explore the effect of long-term alcohol consumption on morning blood pressure surge (MBPS) and its association with left ventricular hypertrophy (LVH) in males with hypertension. Methods According to the findings of our questionnaire survey, 199 male patients with hypertension were divided into non-drinking, giving up drinking and mild, moderate and heavy drinking groups. The fasting plasma glucose (FPG), serum total cholesterol (TC), triglycerides (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), heart rate (HR) and body mass index (BMI) were examined in all patients. The 24-hour ambulatory blood pressure monitoring and echocardiography were performed and the left ventricular mass index (LVMI) were calculated. The data were analyzed by using SPSS 10.0 software. Results The FPG, TC, TG, HDL,LDL HR, BMI and other parameters had no significant differences among the 5 groups (P>0. 05). The levels of 24- hour mean systolic blood pressure(24h SBP), daytime mean systolic blood pressure (dSBP) and nighttime mean systolic blood pressure(nSBP) in the non-drinking, giving up drinking and mild drinking groups were significantly lower than those in the moderate and heavy drinking groups (P<0. 05). The percentages of dipper systolic blood pressure and dipper diastolic blood pressurewere significantly higher, the MBPS value, incidence of increased MBPS, LVMI and incidence of LVH were significantly lower than those in the moderate and heavy drinking groups (P<0. 05). Theabove parameters were not significantly different among non-drinking, giving up drinking andmild drinking groups (P>0. 05). The average daily alcohol consumption was positively correlated with MBPS value andLVMI in the moderate and heavy drinking groups (P<0. 05). Conclusion Long-term moderate and heavy drinking can affect the circadian rhythm of blood pressure, and aggravate MBPS and LVH in males with hypertension. The MBPS and degree of LVH increase with the increase in alcohol consumption.
