Objective To investigate the impact of metoprolol and tongxinluo on the levels of hypersensitivity C -reactive protein (hs -CRP)and NT -proBNP in patients with coronary heart disease.Methods 84 patients with coronary heart disease were randomly divided into the observation group(n =42)and the control group(n =42). The control group was given metoprolol treatment,and the observation group was given metoprolol and tongxinluo treat-ment for 3 months.The echocardiography before and after treatment was inspected.The levels of serum hs -CRP were measured with immune reflection method and the levels of BNP were measured with ELISA.Results The total effective rate,adverse reaction rate of the control group were 95.24%,4.76%,and those of the observation group were 76.19%,23.81%,the differences were statistically significant (P <0.05).The ventricular septal thickness (IVST),left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVDD),left ventricular systolic touch the inside diameter (LVSD)of the observation group were improved than the control group (P <0.05),while the IVST,LVEF,LVDD,LVSD of the observation group after treatment were better than the control group (t =3.996,4.123,3.852,4.256,all P <0.05).The levels of serum hs -CRP and NT -proBNP of the observation group were lower than the control group (t =5.225,7.856,all P <0.05).Conclusion Metoprolol combined with Tongxinluo capsule can improve cardiac function,reduce serum hs -CRP and plasma BNP levels,improve clinical outcomes of patients.

Objective:To investigate the curative effects of Herba houttuyniae injection by spray inhalation and by intravenous drip on lower respiratory tract infection and compare effects.Methods:62 patients with lower respiratory tract infection were divided into the intravenous drip group, spray group 1 and 2 according to sequential trial. The intravenous drip group was treated with Herba houttuyniae injection by intravenous drip, once a day. The spray group 1 and 2 were treated with Herba houttuyniae injection by spray inhalation, once a day and three times a day, respechively.Results:The cure rate of the intravenous drip group was 48% and the total effective rate was 90.48%. The cure rates and total effective rates of the spray group 1 were 25% and 60%. The spray group 2 was 43% and 85.07%.Conclusion:The curative effects of Herba houttuyniae injection by intravenous drip and by spray inhalation (three a day ) on lower respiratory tract infection are similiar and better.

Objective: The kinetic turbidimetric limulus test was used in the endotoxin assay of Sodium Ferulate for injection. Methods: The preliminary validation test was fulfilled, when the standard endotoxin spiked in Sodium Ferulate for injection sample (Lot. No. 20000704) and its 10 fold dilution、 20 fold dilution、 40 fold dilution、 60 dilution、 80 fold dilution. The recoveries were 0.20%, 74.70%, 87.93%, 87.09%, 98.55%, 119.2% respectively. The optimum detection concentration found was 60 fold dilution. During the formal interference tests of 3 batches of Sodium Ferulate for injection (Lot. No. 20000308 20000704 20000315), the recoveries were 120.4%,98.55% and 85.40% respectively. Results: 5.00,0.500,0.0500 Eu/mL of standard endotoxin were used. The standard endotoxin was quantitatively added into the 60 fold dilution of Sodium Ferulate for injection. The recoveries were all 50%～200% and no interference action was found.Conclusion: The kinetict turbidimetric limulus test provided a new way to the detection of endotoxin in Sodium Ferulate for injection.

Objective To realize the isolation of multidrug-resistant organisms (MDROs)from ward environment, and provide evidence for clinical prevention and control of MDRO transmission.Methods Patients with MDRO in-fection in a stomatology hospital from September 2012 to July 2014 were as trial group,12 randomly selected pa-tients without MDRO infection were as control group,environmental object surface in patients’ward were taken specimens and performed culture,isolated organisms were identified and performed antimicrobial susceptibility tes-ting.Results Of 44 patients with MDRO infection,13 patients’surrounding environment were detected MDROs,the total detection rate was 29.55%(13/44).The detection rate of methicillin-resistant Staphylococcus aureus (MRSA),multidrug-resistant Acinetobacter baumannii (MDRAB),and methicillin-resistant Staphylococcus epidermidis (MRSE)were 45.45%(5/11),66.67% (2/3)and 66.67%(6/9)respectively.Detection rates of MRSA from nasal cavity and hands of MRSA-infected patients were 72.73% and 54.54% respectively,from nasal cavity and hands of patients’caregivers were 36.36%and 18.18% respectively.The difference in bacterial count between trial group and control group was not significantly dif-ferent (all P >0.05).Conclusion Isolation rate of MDROs from ward environment of MDRO-infected patients is higher than that of non-MDRO-infected patients,monitoring,cleaning and disinfection for MDRO-infected patients’surrounding environment should be strengthened,so as to prevent the spread of MDROs in hospital.

Objective To investigate the clinical effects of phacoemulsification combined with goniosynechialysis on the treatment of primary angle-closure glaucoma (PACG) with cataract. Methods The retrospective review included 71 patients (98 eyes) with PACG and cataract treated in Tianjin Huanghe Hospital. Patients were underwent phacoemulsification and intraocular lens implantation combined goniosynechialysis. Among these patients, there were 21 males (30 eyes) and 50 females (68 eyes). Patients ranged in age from 53 to 94 years old, everage (73.94 ± 6.43) years old. They were divided into acute angle-closure glaucoma with cataract group (47 patients, 64 eyes) and chronic angle-closure glaucoma with cataract group (24 patients, 34 eyes). The visual acuity, intraocular pressure (IOP), anterior chamber angle, anterior chamber depth (CCT), topical and oral medications and surgical complications were observed before and after surgery in two groups. All the patients were followed up for 6 months. Results At the end of follow-up, postoperative visual acuity, IOP, CCT, anterior chamber angle and IOP-lowing medicine (topical and oral medications) were all improved in the two groups compared with those of preoperative levels (all P < 0.01). There were no statistical differences in preoperative or postoperative average visual acuity, IOP and anterior chamber angle between two groups (all P > 0.05). Values of CCT were significantly higher before and after operation in chronic angle-closure glaucoma with cataract group than those of acute angle-closure glaucoma with cataract group (P < 0.05). No drug-control rate of intraocular pressure was 76.5% (26/34) for chronic angle-closure glaucoma with cataract group than that of acute angle-closure glaucoma with cataract group (100%, 64/64). There was no need on topical medication in acute angle-closure glaucoma with cataract group. There were 14 eyes had corneal edema and 8 eyes appeared iris fibrous exudation in two groups, while no other serious complications. Conclusion For patients with PACG and cataract, the combined surgery of phacoemulsification and goniosynechialysis is a safe and effective therapy that can improve visual acuity and reduce IOP with fewer complications.

Objective To discuss the effect of butylphthalide soft capsules in the treatment of type 2 diabetic patients with mild cog-nitive impairment.Methods Ninety cases of diagnosed type 2 diabetic with mild cognitive impairment were randomly divided into two groups:the treatment group (n=45) and the control group (n=45) .Patients in both groups were treated with the traditional therapy, but those in the study treatment group were given butylphthalide soft capsules.MoCA and P300 were used as the effect judge standard after June.Results Compared with the control group, the MoCA score was increased in the treatment group(P<0.01), P300 latency was shorten and P300 amplitude was increased (P<0.05).Conclusion Butylphthalide capsules can improve cognitive function in patients with type 2 diabetes patients with mild cognitive impairment, and worthy of further clinical promotion and application.

Vasovagal syncope (VVS)is the most common clinical unexplained syncope,and its pathogenesis has not been fully understood yet.The contradictory reflection of cardiac autonomic nervous system caused by riggerring Bezold-Jarisch reflex,which could cause dilated blood vessels,blood pressure and cardiac output decreased,insufficient blood supply to the brain relate with syncope occurrence.Currently,most people consider it mainly relatel to the age and gender of patients,history of syncope,family history,mental and psychological factors,dietary habits and other factors,but the exact risk factors of VVS remains further study of multi-center and a large sample of data.
