Chinese Journal of Biochemical Pharmaceutics 2017;37(8):156-157,160
Objective To study the effects of combination therapy (psychological intervention+clopidogrel+aspirin) for coronary heart disease. Methods 88 cases were selected from January 2016 to April 2017 in patients with coronary heart disease in our hospital. In a randomized approach, patients were divided into treatment groups and control groups, with 44 cases per patient. Patients in the control group were treated with aspirin, and the treatment group was treated with a combination therapy (psychological intervention+clopidogrel+aspirin). The treatment effect, angina and adverse reaction were observed and compared. Results Comparing the therapeutic effect of two groups of patients, the treatment group total effective rate was 97.73%, control group total effective rate was 79.55%, significant difference was statistically significant (P<0.05); Compared two groups of patients with angina, the treatment group patients with onset time (4.32±1.18) shorter, longer time interval (5.03 ±1.34), less number of attacks (1.67±0.49), with statistical significance (P<0.05); Compared to the adverse reactions in the two groups, the incidence of adverse reactions in the treatment group was 4.55%, compared with 18.18% in the control group. Statistical significance (P<0.05). Conclusion Psychological intervention in combination with clopidogrel and aspirin enteric-coated metformin hydrochloride in the treatment, in the clinical treatment of patients with coronary heart disease angina pectoris, shows good therapeutic effect, has higher application value.

Chinese Journal of Primary Medicine and Pharmacy 2011;18(5):590-592
Objective To explore carotid atherosclerosis and its relative factors of maintenance peritoneal dialysis patients. Methods The general clinical conditions,hematobiochemical parameters and color ultrasound parameters of 27 maintenance peritoneal dialysis patients and 24 controll patients were collecled. General clinical conditions included body weight, height and BMI. Hematobiochemical paremeters included Hb, Alb, LP (a), TC, TG, HDL-C,LDL-C, CRP, plasma fibrinogen, C3, Apo-A 1, Apo-B, LP (a). Color ultrasound parameters included plaque incidence rate,thickness of vascularendothelium(IMT). Results Compared with the controll group,maintenance peritoneal dialysis patients: plaque incidence rate, thickness of vascularendothelium (IMT) increased significantly, Age, TC, TG,LDL-C,LP (a), dialysis time increased significantly in plaque-positive group(all p < 0. 05), while Hb, Alb andPAB decreased significantly (all P < 0.0 5) , CRP increased significantly (P < 0.0 1) . Conclusions In maintenance peritoneal dialysis group,CRP,LP(a) had positive relationship with C-IMT. CRP had negative relationship with ALb. CRP had not relationship with age and dialysis time. There were relationships among malnutrition,inflammation and atherosclerosis in maintenance peritoneal dialysis patients. Interdiction of the relationship may played a very important role in ameliorating the prognosis of the maintenance peritoneal patients.
3.Advancing USP compendial methods for fixed dose combinations: A case study of metoprolol tartrate and hydrochlorothiazide tablets
Journal of Pharmaceutical Analysis 2019;9(2):77-82
The current United States Pharmacopeia–National Formulary (USP–NF) includes more than 250 mono-graphs of fixed dose combinations (FDCs), and some of them need to be updated due to incompleteness of impurity profiles and obsolescence of analytical methodologies. A case study of metoprolol tartrate and hydrochlorothiazide tablets is presented to summarize challenges encountered during the USP monograph modernization initiative of FDCs and to highlight an "adoption and adaptation" approach employed for method development. To this end, a single stability-indicating HPLC method was devel-oped to separate the two drug substances and eight related compounds with resolution 2.0 or higher between all critical pairs. Chromatographic separations were achieved on a Symmetry column (C18, 100 mm × 4.6 mm, 3.5 μm) using sodium phosphate buffer (pH 3.0; 34 mM) and acetonitrile as mobile phase in a gradient elution mode. The stability-indicating capability of this method has been demon-strated by analyzing stressed samples of the two drug substances. The developed HPLC method was validated for simultaneous determination of metoprolol tartrate and hydrochlorothiazide and relevant impurities in the tablets. Moreover, the developed method was successfully applied to the analysis of commercial tablet dosage forms and proved to be suitable for routine quality control use. The case study could be used to streamline USP's monograph modernization process of FDCs and strengthen compendial procedures.

Objective To analyze the results and indications of anterior, posterior or combined surgery for thoracolumbar burst fractures. Methods A retrospective review of surgically managed thoracolumbar burst fractures from 1998 to 2003 was performed. There were 76 males and 13 females, and the age of the patients were from 17 to 51 years with an average of 36.8 years. The fractures were located at T11 in 10, T12 in 21, L1 in 29, L2 in 18 and L3 in 11. According to Magerl classification, type A fractures were 68, and type C were 21. Of the 89 patients, 41 received posterior surgeries, 40 anterior surgeries, and 8 combined anterior and posterior surgeries. Operative notes, preoperative and postoperative neurological status, radiographs, CT scans, and follow-up records were reviewed. Results All of the 89 cases had successful surgery. Seventy-eight patients were followed-up for 6 to 48 months (average 12 months). Neurological status improved at least 1 ASIA grade in all of the 65 patients who had preoperative incomplete paraplegia. In the posterior surgeries, pedicle screws broken in 2 cases, deep infection in 1 case which was cured after debridement. The correction of anterior vertebral body height and Cobb's angle averaged 9.4 mm and 14.8? postoperatively, and the correction loss averaged 0.5 mm and 7.5? respectively at 6 months after surgery. And the correction loss was most evident at the above disc spaces, then the below disc spaces. In the anterior surgeries, leakage of cerebrospinal fluid in 2 cases which cured with dressing change, the other cured after debridement, implant removal and posterior fixation. The spinal canal was enlarged, and the spine recovered normal curvature. No evident correction loss, pseudoarthrosis or implant failure was noted at follow-up. Conclusion The choice of anterior, posterior or combined surgery for thoracolumbar burst fractures depends on neurological status and column stability. The vertebral compression, canal encroachment, posterior column stability and concomitant displacement should be considered in the choice of appreciate surgical approach.
