0.05).The off-pump group had a shorter respiratory support time [(4.8?1.9)h vs(8.9?2.1)h,t=17.453,P=0.000],less drainage volume[(390?152)ml vs(660?111)ml,t=17.173,P=0.000],and required less blood transfusion [(270?77)ml vs(510?144)ml,t=17.861,P=0.000] than the on-pump group.In the off-pump group,3(2.0%)of the 150 patients developed renal function injury that is significantly more than that in the on-pump group [11/140(7.9%),?2=5.407,P=0.020].Conclusions Off-pump CABG is as effective as the on-pump surgery;moreover,it is a better choice for patients with high-risk coronary disease since this technique is superior in reducing respiratory support time,volumes of chest drainage and blood transfusion,and renal function injury.

Nasal spray can treat local diseases such as rhinitis, it also plays an important role in the treatment of systemic diseases including vaccine immunity. As a drug-device combination product, spray pattern is often used as the quality indicator of nasal spray to ensure its quality, plume geometry can not only be combined with the spray pattern to evaluate the performance of the nasal spray, but also can predict the deposition of the nasal spray in the nasal cavity. This article systematically reviews the definition and measurement methods of the spray pattern and plume geometry of nasal spray and their correlation with nasal deposition behavior. The measurement parameters of spray pattern and plume geometry are defined. The influence of formulation, device and trigger parameters on spray pattern and plume geometry is clarified. The correlation between various parameters and nasal deposition is analyzed. The measurement parameters are classified according to the size and shape of the spray. Plume angle is closely related to the deposition of drugs in the nasal cavity. Jet-like plume with a smaller plume angle can increase the navigation ability of the nasal spray in the curved anatomical structure of the nasal cavity, which is conducive to increase drug deposition. This makes it possible to increase deposition of the nasal spray in the nasal cavity

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.
METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.
RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).
CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

Chinese patent orthopedic medicines feature complex components, mainly including desperate and toxic herbal pieces, narrow safety window, more clinical contraindications and frequent adverse drug reaction/events (ADR/ADE). To study the general safe medication regularity of Chinese patent orthopedic medicines, define key points in the medication education and ensure rational clinical medication, the authors took 80 types of commonly used Chinese patent orthopedic medicines as the study objects, collect 237 cases from 164 ADR/ADE documents through a system retrieval strategy, make a multidimensional literature analysis to determine the common risk factors for safe and rational medication of Chinese patent orthopedic medicines and establish an ADR/ADE prevention regularity. First, in the aspect of clinical symptoms, skin allergy is the most common ADR/ADE and closely related to the toxic ingredients, particularly accumulated liver or kidney damage caused by some drugs. Second, there are three time nodes in the ADR/ADE occurrence; The ADR/ADE occurred in 30 minutes is closely related to the idiosyncrasy; the ADR/ADE occurred between several months and half a year is related to the drug-induced liver and kidney damages; The most common ADR/ADE was observed within 7 days and predictable according to the pharmacological actions; Third, toxicity is an important factor in the occurrence of ADR/ADE of Chinese patent orthopedic medicines. Fourth, emphasis shall be given to the special medication factors, such as the combination with western medicines and Chinese herbal decoctions, overdose and long-course medication and self-medical therapy. In conclusion, the general ADR/ADE prevention regularity for Chinese patent orthopedic medicines was summarized to provide supports for clinicians in safe and rational medication and give the guidance for pharmacist in medication education.

In this article, the implementation of eye movement tracking system includes three procedures: hardware acquisition, data extraction and overall analysis. The system is based on Camshift algorithm with an eye tracking module added, developed on VC++ 6.0. The system can track the eye movement effectively in simulated phosphene evaluation experiment based on prosthetic vision.

Objective The purpose of this study was to investigate the value of serum galactomannan (GM) in the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with chronic obstructive pulmonary disease (COPD).Methods We enrolled 60 COPD patients in the study, including 19 IPA and 41 non-IPA cases.We examined serum GM of the patients by ELISA, evaluate the value of serum GM test for the diagnosis of IPA in patients with COPD, and compared the GM values before and after treatment.Results With 0.5 as the positive cutoff value, the sensitivity, specificity, positive predictive value, and negative predictive value of serum GM were 57.9%, 95.3%, 84.6%, and 83.0%, respectively, with a high specificity and a low sensitivity.The 7 IPA cases showed a significantly decreased GM value after treatment as compared with the baseline (0.30±0.21 vs 1.48±1.37, P=0.004).Conclusion The serum GM test has a limited value in the diagnosis of IPA in patients with COPD, but dynamic monitoring of the changes of the serum GM value may help evaluate the patient's condition.

Objective To evaluate the technical feasibility and safety of endoscopic retrograde catheterization of gallbladder (ERCG) and endoscopic transpapillary gallbladder stenting (ETGS) for gallbladder diseases.Methods Patients who underwent ERCG and ETGS in Eastern Hepatobiliary Hospital from January 2010 to June 2016 were enrolled to this retrospective study.The superselection time of cystic duct,the catheterization time of gallbladder,postoperative symptoms and complications were analyzed.Results A total of 10 patients were enrolled to this study,including 2 cases of acute calculous cholecystitis,4 cases of percutaneous transhepatic gallbladder drainage (PTGBD) and 4 cases of cholecystocholedocholithiasis.The success rates of ERCG and ETGS were 100%.Symptoms were relieved in all patients and PTGBD catheter was removed after ETGS.The mean times of ERCG and ETGS were 10.2 ± 6.9 min and 17.0 ± 8.0 min respectively.The mean times of ERCG were 18.5±4.9 min,13.0±3.6 min and 3.3± 1.3 min,respectively (F=18.86,P =0.002).The mean times of ETGS were 25.5±4.9 min,21.0± 4.7 min and 8.8 ± 1.0 min,respectively (F =18.04,P =0.002).Complications included 1 case of cholangitis and 1 case of hyperamylasemia.Cholangitis was relieved after anti-inflammatory treatment.No acute pancreatitis,bleeding,perforation or procedure-related death occurred.Conclusion ERCG and ETGS are safe and feasible,which can play important roles in the treatment of specific gallbladder diseases or gallbladder with bile duct diseases.
