Sterilization is one of the key links in the production of traditional Chinese medicine,and it is also an important factor to ensure the safety,effectiveness and quality control of traditional Chinese medicine.Traditional sterilization techniques such as moist heat sterilization are limited in many cases due to their inherent shortcomings.In contrast,irradiation sterilization has attracted more and more attention due to its advantages of fast,efficient,strong sterilization and low cost.However,the chemical composition of traditional Chinese medicine is complex,due to the radioactivity and strong penetration of irradiation,after a certain dose of irradiation,its chemical composition and pharmacological activity may change.At present,there is still a lack of systematic research on the changes of chemical composition,effectiveness and safety of traditional Chinese medicine after irradiation sterilization.Based on the research status of 60Co-γ ray and electron beam irradiation sterilization in the sterilization of traditional Chinese medicine in recent years,this paper reviews the effects of irradiation on the effectiveness of traditional Chinese medicine,the detection methods of irradiation and the safety evaluation,in order to provide some reference for the subsequent application of irradiation sterilization of traditional Chinese medicine.

Objective:To explore the treatment of iatrogenic injury to the medial collateral ligament (MCL) in total knee arthroplasty (TKA).Methods:From January 2009 to December 2016, 14 patients were treated at Department of Arthropathy, Zhengzhou Orthopedics Hospital for iatrogenic MCL injury in primary TKA (injury group). They were 3 males and 11 females with an age of (72.6±3.9) years. The MCL injury was body rapture in 9 cases and avulsion of femoral insertion in 5 ones. Interlacing suture was used for body rapture and reparative reconstruction with wire anchors or nails was performed for avulsion of femoral insertion. A restrictive condylar prosthesis was used instead in the 4 patients whose medial stability failed to be restored after repair of body rapture. A control group of 21 cases was enrolled who had suffered from no iatrogenic MCL injury in primary TKA at the corresponding period. There were 5 males and 16 females with an age of (73.2±3.9) years. The 2 groups were compared in terms of American Knee Society Score (KSS) and knee flexion.Results:There was no significant difference between the 2 groups in preoperative general data, showing comparability between groups ( P>0.05). The injury group was followed up for 18 to 36 months (mean, 33 months). Joint loosening was observed at 18 months after operation in 3 patients with nonrestrictive prosthesis who had to receive secondary revision. At the 36-month follow-up of the remaining 11 patients, normal knee extension and flexion was observed, the stress test of valgus showed no inner relaxation, their KSS increased significantly from preoperative 50.0±22.7 to 93.3±4.7, and their knee flexion was improved significantly from 90.4°±10.3° to 110.7°±8.8° ( P<0.05). There were no significant differences in KSS score or knee flexion between the 2 groups at 3, 6, 12 or 36 months after operation ( P>0.05). Conclusion:Iatrogenic MCL injury in primary TKA should be repaired and reconstructed by one-stage surgery because the patients can achieve curative results similar to those for the patients free from iatrogenic MCL injury in primary TKA.

Objective: To compare the value of two 3D imaging reconstruction methods for left atria and pulmonary vein on guiding the catheter ablation for atrial fibrillation (AF). Methods: From January 2014 to January 2017, a total of 100 drug refractory paroxysmal AF patients were divided into left atria direct angiography group (n=50), and indirect angiography group (n=50). 3D CARTO system was applied for mapping and guiding the ablation procedure. Patients assigned to direct angiography group were treated as follows: intraoperative puncture of atrial septum, inject contrast agent directly into the left atrium, conduct left atrial and pulmonary venous rotation angiography, reconstruct three-dimensional image, integrate the image into real-time X-ray system to facilitate circumferential pulmonary vein isolation. Patients assigned into the indirect angiography group were treated as follows: inject contrast agent through the right ventricle, conduct delayed rotation angiography of the left atria and pulmonary vein to guide circumferential pulmonary vein fixation and ablation. The left atrial and pulmonary venous image acquisition, the operation and X-ray exposure time, the success rate and the incidence of complication of the two groups were compared. The patients were followed up for 3-6 months. Results: General clinical characteristics of the two groups were similar(all P>0.05). Ablation was successful in all 100 patients. The operation time[(112.0±21.4)min vs. (134.0±24.3)min]and X-ray exposure time((10.7±4.7)min vs. (15.8±5.2)min)were significantly lower in direct angiography group than in indirect angiography group (both P<0.01). There was no significant difference between the two groups in the immediate (86%(43/50) vs. 82%(41/50), P=0.59) and short-term (76%(38/50) vs. 72%(36/50), P=0.65) success rate and complication rate (1 aneurysm in the direct angiography group, 1 pericardial tamponade in the indirect angiography group). In-hospital mortality was zero percent. Conclusion It is safe and effective method to guide the radiofrequency catheter ablation of paroxysmal atrial fibrillation by reconstruction 3D image of left atrium and pulmonary vein. Compared with indirect angiography group, direct angiography group can improve the imaging quality of left atrium and pulmonary vein, decrease the X-ray exposure time of the ablation procedure.

Objective: To investigate the safety and efficacy of CARTO3 fast anatomical mapping during radiofrequency ablation in patients with paroxysmal atrial ifbrillation (PAF). Methods: A total of 120 PAF patients treated in our hospital from 2013-01 to 2015-07 were enrolled. All patients received CARTO3 system for mapping and they were randomly divided into 2 groups: Control group, the patients had selective pulmonary vein angiography, followed by conventional point by point method to reconstruct left atrial model for guiding the ablation of PFA and Treatment group, the patients had selective pulmonary vein angiography followed by fast anatomical mapping to build left atrial model for guiding the ablation of PFA; the rest operational steps such as trans-septal and circumferential pulmonary vein ablation were the same.n=60 in each group. The times of operation, X-ray exposure and the rates of success, complication occurrence were compared between 2 groups. Results: All patients were successfully completed radiofrequency ablation for PAF. Compared with Control group, Treatment group had increased modeling time (8.5 ± 3.6) min vs (5.2 ± 2.3) min, while decreased pulmonary vein ostium determing time (12.0 ± 5.6) min vs (25.0 ± 8.4) min, circumferential pulmonary vein ablation time (95.0 ± 22.0) min vs (115.0 ± 25.0) min and X-ray exposure time (15.0 ± 6.3) min vs (24.0 ±5.5) min, allP<0.05. The rates of success and complication occurrence were similar between 2 groups, P>0.05. Conclusion: CARTO3 fast anatomical mapping is safe and effective for guiding radiofrequency ablation in PAF patients, it may decrease the X-ray exposure time and operation time which were important for treating the relevant patients.

Objective To evaluate the clinical performance of high-risk human papillomavirus ( HR-HPV) E6/E7 mRNA test in female in different groups with atypical squamous cell of undetermined significance ( ASC-US) cytology.Methods 320 samples from female patients with ASC-US were detected with HR-HPV E6/E7 mRNA test and HR-HPV DNA test simultaneously, patients were examined with colposcopy and cervical biopsy.They were divided into two groups:younger than 30 years and 30 years and older.The statistical analysis were performed.Results There were no statistically significance in the positive rate of HR-HPV E6/E7 mRNA between two groups ( P>0.05) .In the group aged younger than 30 years, the positive rate of HR-HPV DNA was significantly higher than the group aged 30 years and older ( P<0.05),but the prevalence of CINⅡor greater was significantly lower than the other group (P<0.05).In the group aged younger than 30 years, the specificity of HR-HPV E6/E7 mRNA test for detection of CINⅡor greater was 68.0%,which was significantly higher (P<0.05) than that of HR-HPV DNA test 38.7%, meanwhile, the specificity of HR-HPV E6/E7mRNA test for detection of CINⅡor greater was significantly higher ( P<0.05) than that of HR-HPV DNA test ( 76.5% vs 69.4%) in the group aged 30 years and older.There were no statistically significance (P>0.05) in sensitivity, positive predictive value(PPV) and negative predictive value( NPV) between the two tests in each group.Conclusion Comparing to HR-HPV DNA test, HR-HPV E6/E7mRNA test is more suitable for triage of ASC-US including female patients who were younger than 30 years.

This study was aimed to investigate the effects of Chai-Hu Shu-Gan Tang (CHSGT) on levels of TNF-α and 5-HT in lithium chloride–pilocarpine caused epilepsy–depression comorbidity rat model, in order to discuss the intervention effect of CHSGT on TNF-α and 5-HT in epilepsy–depression comorbidity. The lithium chloride–pilocarpine caused epilepsy–depression comorbidity rat model was established. After 6 weeks of animal establishment, rats were randomly divided into 5 groups, which were citalopram group (A), physiological saline group (B), CHSGT high dose group (C), medium dose group (D), and low dose group (E). Intragastric administration was given for 4 weeks, twice a day. Before and after the treatment, RT-PCR was performed to detect hippocampal TNF-αlevels. Liquid chromatography-mass spectrometry was performed to detect hippocampal 5-HT levels. Both forced swimming test (FST) and saccharin preference test were carried out to monitor the depressive behaviors of rats. In the meantime, 24 hours a day video camera surveillance were performed to record the number of seizures of rats. The results showed that after treatment, the number of seizures of rats were significantly reduced, the accumulative immobility time in FST was shortened, and the consumption of sucrose increased significantly (P < 0.01) in group A, C and D. Compared with group B, after the treatment, the expressions of hippocampal TNF-α mRNA of rats in group A, C, D were distinctly downregulated, with the level of 5-HT significantly increased (P < 0.05,P < 0.01). Compared with group A, group C and D showed no significant changes. It was concluded that TNF-α played a role in the pathogenesis of epilepsy–depression comorbidity through mediating the level of 5-HT. High and medium doses of CHSGT can downregulate the expression of TNF-α mRNA in depression comorbidity of chronic temporal lobe epilepsy, increase 5-HT level, reduce the number of seizures of rats, and improve depressive behaviors.

Objective To investigate the protective effect of allopurinol in kainic acid-induced epileptic rats and to explore new ideas and methods for the clinical treatment of epilepsy. Methods 120 Wistar rats were randomly divided into sham group, KA epilepsy group and allopurinol groups. Six rats of each group were randomly selected and were given electrodes into their left frontal and hippocampal regions. After injection, behavior changes were observed in all rates without electrodes. 24 h later, MDA level and SOD enzymatic activity of the left hippocampi were measured. One week later, the EEGs were recorded in rates with electrode, as well as total time of seizures /30 min and numbers of seizures / 30 min. Results Compared with the KA model group, latency period of the epilepsy in the allopurinol group was longer (P < 0.05) and the extent was lighter (P < 0.05); the MDA level was significantly lower (P < 0.01), the SOD enzymatic activity was significantly higher (P < 0.01). The total time of seizures / 30min and numbers of seizures / 30 min in allopurinol group reduced significantly (P < 0.01). Conclusion Allopurinol has potential antiepileptic and antioxidative activities in kainic acid-induced epileptic rats.
