Objective To investigate the efficacy and safety of perioperative use of different hemostatic drugs in elderly patients undergoing transurethral resection of the prostate (TURP).Methods A total of 480 elderly patients with benign prostatic hyperplasia (BPH) admitted to the Departments of Urology and Gerontology of our hospital from January 2010 to October 2014 were selected and randomly divided into 6 groups (n =80,each).Patients in all groups were given preoperative oral finasteride for 1 week,with each of the non-control groups receiving perioperative heamocoagulase agkistrodon,mangabeys hemocoagulase,reptilase,ethylenediamine diaceturate,or dicynone + paraaminomethyl benzoic acid (PAMBA).Intraoperative bleeding,perioperative hematocrit,hemoglobin change,continuous bladder irrigation time,adverse reactions and other clinical parameters were recorded.Results Operations went smoothly with all patients.Changes in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time had significant differences between the control group and the groups treated with hemostatic drugs (all P＜0.05).No significant differences in perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time were found between groups treated with heamocoagulase agkistrodon,mangabeys hemocoagulase and reptilase,or between groups treated with ethylenediamine diaceturate and dicynone+PAMBA (all P＞ 0.05).There were significant differences in the perioperative blood routine indexes,coagulation function,intraoperative bleeding volume and continuous bladder irrigation time between the groups with and without blood coagulation enzymes (all P ＜0.05).Fibrinolytic responses occurred in 2 patients in the heamocoagulase agkistrodon group and were mitigated after drug withdrawal and fibrinogen infusion.Conclusions A reasonable perioperative dose of a hemostatic drug has good clinical effects in elderly patients undergoing TURP.Hemostatic drugs such as blood coagulation enzymes have certain advantages including safety over other types of hemostatic drugs,but their doses should not be too large.

Objective To investigate the diagnosis,treatment and prognosis of bilateral renal clear cell carcinoma in the elderly.Methods Clinical data from 38 cases of elder patients admitted with bilateral renal clear cell carcinoma in our department from 2010 to 2014 were retrospectively analyzed.Among the total 38 cases diagnosed by B ultrasound and CT,13 cases(A group)were treated with laparoscopic radical nephrectomy on one side,combined with microwave ablation on the other side;another 25 cases(B group)were treated with microwave ablation on bilateral sides.Patients were followed up for 24-36 months,with regularly checking by B ultrasound,CT and renal function.Results The operations were successful in total 38 cases (A +-B group),and no postoperative complications were found.All cases were diagnosed as pathologically proven bilateral renal clear cell carcinoma.Postoperative renal functions of the cases were decreased at different degrees as compared with preoperative renal functions,but not needing dialysis treatment.The microwave ablation on bilateral sides(B Group) versus A Group,significantly decreased the surgical time cost (P =0.012) and hospital stay(P =0.021).For both A and B group,postoperative renal function were declined in different degree.The damage extents of blood urea nitrogen,creatinine and creatinine clearance rate were less in group B than in group A at one week after surgery(P=0.008,0.009 and 0.006).Atpostoperative follow-up for 3 month,it was found that the damage extents of blood urea nitrogen,creatinine and creatinine clearance rate were less in group B than in group A (P =0.037,0.020 and 0.018).At postoperative follow-up for 30 months in average,no local recurrence or metastasis was found.Diagnosis of bilateral kidney clear cell carcinoma in the elderly mainly depended on B ultrasound,CT scan and MRI imaging.Conclusions As to the treatment of elderly patients with early renal clear cell carcinoma,considering both the general healthy condition of patients and tumor therapy and choosing microwave ablation might be good for efficiency and prognoses.

Objective The aim of this study is to evaluate the efficacy and safety of preoperative CT-guided hardening agent localization.Methods From December 2010 to January 2012,27 patients with 29 solitary pulmonary nodules who had undergone CT-guided hardening agent localization and video-assisted thoracoscopic surgery (VATS) were studied.Results All cases were underwent CT-guided hardening agent localization successfully,and no patient had serious complication that required any intervention.The diameter of nodules ranged from 3 to 21 mm as measured by CT[mean (11.27 ± 6.32) mm].The distance between the center of nodule and visceral pleural ranged from 4 to 38 mm[mean (14.45 ± 4.32) mm].Conversion from VATS to thoracotomies was not necessary during the diagnostic resection procedure nodules.29 solitary pulmonary nodules underwent thoracoscopic wedge resection,and no intra-or postoperative mortality or morbidity was recorded.Conclusion CT-guided hardening agent localization before video-assisted thoracoscopic solitary pulmonary nodule resection is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.

OBJECTIVETo evaluate the value of UV absorption spectrum for identification and quality control of compound Danshen tablets and pills.

METHODUV absorption spectra of compound Danshen tablets and pills, and other drugs were scanned using ultraviolet spectrophotometer (water as the solvent). Pearson's correlation coefficients (Pearson's R) were displayed in the correlations table obtained from SPSS correlate, and deltaR defined as the absolute value of the difference between Pearson's R and its mirror image in the table were used for measuring the spectral similarity between two drugs from different manufacturers.

RESULTRegarding compound Danshen tablets and pills, the spectral similarity between different batch drugs from same manufacturer was very high with Pearson's R = 0.995-0.9999, and the similarity between two manufactures was high with Pearson's R = 0.92-0.997 and deltaR < 0.02. Compared with the spectra of compound Danshen tablets and pills, the spectral similarity of the other drugs was low with Pearson's R = 0.25-0.98 and deltaR > 0.02.

CONCLUSIONThe results showed that UV absorption spectrum could be suitable for identification and quality control of compound Danshen tablets and pills.

From the hospital information system (HIS) of 20 national grade III-A general hospitals, 2 960 cases of herpes zoster as the research object, analyzes the relations between the general information, syndrome of traditional Chinese medicine (TCM), western medicine combined diseases, the relationship between the solar term and the incidence of herpes zoster, and the combined use of Chinese and western medicine. Among the patients with 46-65 year old has the highest percentage of diseased; admission to general outpatient clinic is the most; the most common medical payment is medicare; combined disease such as hypertension, diabetes and coronary heart disease is more common; early treatment effect of herpes zoster is better than the sequelae; summer and autumn solar term patients is hospitalized more, TCM syndrome is damp heat of liver fire; about drugs, western medicine is the most commonly used vitamin B1 and mecobalamin, traditional Chinese medicine is the most frequently used Danhong injection, combination therapy with promoting blood circulation drugs and neurotrophic drugs. Thus, herpes zoster, more common in elderly patients, with no obvious relationship between solar term, should be early diagnosis and early treatment, often with combination of Chinese traditional and western medicine treatment.

Qigui Tongfeng tablet (QLTFT) is a traditional Chinese medicine with good effect for treating gout. Here, network pharmacology method and molecular similarity analysis were utilized to study the effective substance basis and molecular mechanism of the QLTFT on the gout. The similarity to the medicinal compounds is reflected in the Tanimoto coefficient that gives the structural similarity of two compounds. Operationally, similar modifiers were described as pairs of concepts with a similarity score of 0. 500. The results of the molecular similarity analysis suggested that the flavonoids in QLTFT could be new leads for gout. Furthermore, complex biological systems may be represented and analyzed as computable networks. Two important properties of a network were degree and betweenness. Nodes with high degree or high betweenness may play important roles in the overall composition of a network. And the results of network analysis showed that dongbeinine, verticinone-N-oxide, verticine N-oxide, peimine, peiminine, isobaimonidine, dongbeirine, peimisine and simi-arenol which with high degree acted on xanthine dehydrogenase/oxidase, matrix metalloproteinase-9, an arachidonate 5-lipoxygenase-activating protein, tyrosine-protein kinase and etc. Inhibition of these targets can prevent the formation of uric acid, reduce inflammation by uric acid and regulate the body's immune response. Thus, these compounds may be the main effective substance basis. The research results not only reveals its molecular mechanism, but also provide a theoretical basis for the quality control of drugs and clinical application.
