AIM: To research the application analysis of trabeculectomy combined with phacoemulsification treating patients with primary angle-closed glaucoma ( PACG) and cataract.
METHODS: Seventy-three patients from September, 2011 to September, 2013, with primary angle- closed glaucoma and cataract, were selected in our research. Patients were all treated with trabeculectomy combined with ultrasonic emulsification, and the therapeutic effect was observed.
RESULTS: The effects of trabeculectomy combined with phacoemulsification treating primary angle-closed glaucoma and cataract in reducing intraocular pressure were better, and postoperative visual acuity results of the research objects were satisfactory. And it could deepen the central anterior chamber depth effectively. All the research objects had few complications.
CONCLUSION: Trabeculectomy combined with phacoemulsification treating primary angle - closed glaucoma and cataract can achieve a good result for reducing intraocular pressure, postoperative visual acuity recovery and correction, and the surgical success rate is high, with low complication rates. It is worthy of widely clinical application.

OBJECTIVE: To establish the method to analyze γ-hydroxybutyric acid (GHB) and its precursors 1,4-butanediol (1,4-BD) and gamma-butyrolactone (GBL) in urine through LC-MS/MS and provide evidence for related cases. METHODS: GHB-d6 and MOR-d3 were used as the internal standard. The urine sample was separated by LC after protein precipitation with methanol. The electrospray ion source was for ionization. Each compound was detected through multiple-reaction monitoring (MRM) mode. RESULTS: The limits of detection of GHB and its precursors 1,4-BD and GBL were 0.1, 0.1 and 2 μg/mL. The accuracy was 87.6%-98.1%. The intra-day and inter-day precisions were less than 15% and matrix effects were higher than 80%. CONCLUSION The method is high sensitive, simple, rapid, specific and with high reliability. This study has provided technical support and basic data for forensic cases involving GHB.

The phytase was extracted from solid state leavening of Trichoderma Viride LH374.The crude product was purified by(NH_4)_2SO_4 precipitation,gel filtration and ion exchange chromatography.The purified phyatse was 13.3 times of the raw products,and the extraction ration was 27.1%.The study on the enzymology of phyatse showed that the optimal temperature and pH were 55℃ and 6.0,respectively.The Km value of the phytase was 0.15mmol/L.

Objective One typical case with stress cardiomyopathy was reported and the current knowledge of the syndrome was reviewed to improve relevant knowledge.Methods A 71-year-old female patient presented dyspnea and chest pain due to emotional stress.ECG,echocardiography,selective coronary artery angiography,left ventriculography,~(99)Tc~m-MIBI single photon emission computed tomography (SPECT),~(18)F-FDG SPECT and MRI were performed.Results Electrocardiogram at admission showed ST segment elevation and T wave inversion in leads V1—V4.Pathological Q wave occurred 1 week later,it disappeared 1 month later however and severe T wave inversion occurred.Normal or slightly elevated cardiac enzymes in the blood were found during the course.Left ventriculogram at admission showed left ventricular apical ballooning with LVEF of 30%.The ballooning volume was about 3/4 of left ventricular volume, without any corresponding coronary artery diseases found in coronary angiogram.The abnormal apical ballooning decreased significantly in the follow-up left ventriculogram performed one month later.The LVEF rose up to 63.6%.~(99)Tc~m-MIBI and ~(18)F-FDG SPECT showed mismatch of perfusion and metabolism in the corresponding region,indicating presence of viable myocardium.MRI showed left ventricular apical ballooning without perfusion defect and late enhancement,indicating viability of corresponding myocardium. Conclusions Emotional stress can cause transient left ventricular apical ballooning called"stress cardiomyopathy".Either ~(99)Tc~m-MIBI SPECT associated with ~(18)F-FDG SPECT or delayed enhancement MRI plays an important role in identification of myocardial viability,which can efficiently guide clinical treatment.

During the process of growth, harvesting, transportation, processing and storage, Chinese herbal medicines (CHMs) can be easily contaminated by fungi and their metabolites like mycotoxins, which not only express negative effects on the quality and safety of CHMs and their processed products, but also pose great threats to human health. Now, some chemical synthetic fungicides have been frequently used to control the growth of fungi and accumulation of mycotoxins in the preservation of CHMs. However, the concentration and type of chemical fungicides allowed for postharvest application are restricted due to the disadvantages of their high residual toxicity, long degradation period and pollution to the environment and so on. Therefore, it is critical to research and develop some highly effective, safe and non-toxic, natural, environment-friendly fungistatic agents from plants to prevent CHMs from being contaminated by fungi and mycotoxins. The paper reviews mycotoxins and their harmfulness, the effective compounds of fungistatic plants as well as the antifungal mechanism to provide scientific evidences for developing novel and effective fungistatic agents plants. Then, the application prospect of fungistatic agents from plants in the preservation of CHMs was discussed.

A total of 104 patients with polycystic ovarian changes on ultrasound were divided into polycystic ovary syndrome (PCOS) and polycystic ovaries (PCO) groups according to their clinical symptoms and endocrine examinations.And 40 women with normal ovulation served as the controls.Ovarian volume (OV),ovarian stroma area (SA),ovarian total area (TA) and SA/TA ratio were measured by transvaginal uhrasonography.Their endocrine hormone levels were determined.Patients with PCOS showed significantly higher OV,SA,TA and SA/TA than those of PCO and control groups.SA/TA was positively correlated with testosterone.The median serum levels of anti-Mullerian hormone (AMH) and inhibit B in the PCO group were intermediate between those in control and PCOS groups.AMH and inhibin B of PCOS were higher than the PCO and control groups.It indicated that the levels of AMH and inhibit B were associated with the degree of polycystic ovaries and they could be used to differentiate PCOS and PCO.SA/TA is associated with the elevated serum testosterone of PCO.And SA/TA is an important ultrasonic parameter for diagnosing PCOS.

Objective To assess the value of procalcitonin(PCT)measurement to differentiate infection from non-infection in critically ill patients requiring long-term immunosuppressive therapy.Methods A prospective study was conducted in patients with underlying diseases requiring corticosteroids or chemotherapy in ICU from January 2008 to December 2009.Patients were divided into the infection group and the non-infection group and their PCT levels were compared.Results A total of 103 patients (65 women)were enrolled in this prospective study[aged(47.9 ± 21.9)years old]with 84 in the infection group and 19 in the non-infection group.The baseline level of PCT was significantly higher in infection than in non-infection patients[2.58(0.08-44.65)pg/L vs 0.62(0.15-6.00)pg/L,P =0.002].Different levels of PCT were manifested in different pathogen groups with 3.41(0.45-44.65)pg/L in bacteria infection,0.99(0.28-6.67)pg/L in fungus infection,0.11(0.08-0.20)pg/L in virus infection group(P =0.018).The AUCROC of PCT was 0.867 for diagnostic bacterial infection.By multivariate analysis,the factors associated with the level of PCT were bacteria infection(OR 5.1,P =0.031)and septic shock(OR 7.5,P =0.027),while the factors not associated with the level of PCT were age,renal function,infection site and prognosis(P ＞ 0.05).Conclusions The level of PCT is increased in the critically ill patients requiring immunosuppressive therapy with infection and it can be used for diagnosis for bacterial infection.
