OBJECTIVE:To establish the quality standard for Tongmai pill. METHODS:TLC was used for the qualitative iden-tification of Salvia miltiorrhiza,Angelica sinensis and Carthamus tinctorius. HPLC was used for the content determination of feru-lic acid. The column was Diamonsil C18 with mobile phase of acetonitrile-0.1% aqueous phosphoric acid (17∶83,V/V) at a flow rate of 1 ml/min,the detection wavelength was 316 nm,the column temperature was 30 ℃,and the injection volume was 10 μl.. RESULTS:The TLC of S. miltiorrhiza,A. sinensis and C. tinctorius showed clear spots and good separation. The linear range of ferulic acid was 8-80 μg/ml(r=0.999 8);RSDs of precision,stability and reproducibility tests were lower than 2%;recovery was 97.2%-99.6%(RSD=1.2%,n=6). CONCLUSIONS:The standard can be used for the quality control of Tongmai pill.

Objective To observe the clinical effect of modified laparoscopic adrenalectomy for adrenal pheochromocytoma. Methods 23 patients with adrenal pheochromocytoma were treated with modified posterior laparoscopic adrenalectomy. The changes of blood pressure, heart rate, operation time and blood loss during and after operation were observed. Results 23 patients were successfully operated, the operation time was (62.3 ± 11.7) min, the intraoperative blood loss was (34.4 ± 17.7) ml, there has no hemorrhage occurred while 3 cases were transferred to ICU for intraoperative blood pressure and heart rate fluctuation significantly, and back to general ward after 2 days, while there was no significant difference in blood pressure and heart rate preoperatively. Conclusion Modified laparoscopic adrenalectomy is safe and effective for pheochromocytoma and holds the advantages of clear anatomy, short operative time, less bleeding and less change in blood pressure and heart rate.

Objective To investigate the long-term outcome of radical prostatectomy (RP) in the patients with incidental prostate cancer (IPCa) detected by surgery of benign prostatic hyperplasia (BPH) and to evaluate the risk factors for residual tumour after BPH surgery and biochemical recurrence in patients with IPCa treated with RP.Methods We retrospectively analyzed the clinical and follow-up data of 45 patients with IPCa detected by surgery of BPH and undergoing RP from January 2004 to October 2016.The age,PSA before and after BPH surgery,prostate volume,T stage and Gleason score after the BPH surgery,T stage at RP (pT0,pT2,pT3),Gleason score at RP and status of biochemical recurrence were recorded.Multivariate logistic regression analysis addressed the association between the factors and the presence of residual cancer after the surgery for BPH.Cox regression was used to analyzed the relationship between the factors and the rate of biochemical recurrence after RP.Results Among 45 IPCa patients,21 patients were stage T1a and 24 were stage T1b.After RP,7 (15.6％) patients had no residual tumor (pT0).PSA before BPH surgery (RR =2.58,95％ CI 1.27-5.42,P =0.04),PSA after BPH surgery (RR =4.26,95％ CI 2.57-7.64,P =0.01) and Gleason score after BPH surgery (RR =3.98,95％ CI 1.85-5.77,P =0.02) were significant associated factors with the residual cancer after BPH surgery.With a mean follow-up of 54 months(ranging 5-144 months),the 5-and 10-years.biochemical recurrence-free survival rates were 95.6％ and 86.7％,respectively.PSA after surgery for BPH (RR =4.79,95％ CI 2.57-7.64,P =0.02) and Gleason score after RP(RR =2.01,95％ CI 1.74-5.21,P =0.04) were the only independent risk factors for biochemical recurrence.Stage (T1a-T1b) did not predict residual cancer or the rate of biochemical recurrence (P ＞ 0.05).Conclusions RP in the patients with IPCa detected by BPH surgery had a good outcome of long-term oncological control.PSA before and after BPH surgery and Gleason score at BPH surgery were the significant associated factors of residual cancer after BPH surgery.PSA after BPH surgery and Gleason score at RP were the only independent risk factors for biochemical recurrence.

Objective To investigate oral health-related quality of Life(OHRQoL)in end-stage renal disease Patients undergoing hemodialysis(HD) and its influencing factors. Methods Through convenient sampling, totally 185 HD patients in two first-class tertiary hospitals in Changchun were investigated with the Oral Health Impact Profile-14(OHIP-14) . Influencing factors of oral health-related quality of life of patients were extracted from patients'general information and oral health behavior questionnaire. Single factor analysis and multivariate linear stepwise regression analysis were used for statistical analysis. Results The scores of oral health-related quality of life in hemodialysis patients were Significantly higher than those of the normal population in China(P<0.05)and age, duration of hemodialysis, status of smoking, frequency of brushing, brush teeth time, status of using mouth wash, and frequency of oral examination were influencing factors for oral health-related quality of life of HD patients, (β=-0.156-0.164, all P<0.05). Conclusions Oral health-related quality of life in HD patients is poor. Medical workers should pay attention to older patients with longer duration of hemodialysis and poor oral health behavior, take effective interventions to improve oral health-related quality of life of HD patients.

Objective To investigate the effect of tyrosine kinase inhibitor(TKI)on radioiodine-refractory differentiated thyroid carcinoma(RAI-rDTC).Methods Literature related to RAI-rDTC was retrieved from Wanfang Data,CNKI,VIP,PubMed,Cochrane,EmBase and Medline databases until December 31,2021.Literature quality and experimental bias were referred to the Cochrane quality risk assessment table,and Meta-analysis was performed using RevMan 5.3 software.Results A total of 1384 patients were included in 6 studies.The results of Meta-analysis showed that the median progress free survive(HR=0.30,95%CI:0.18-0.50,P<0.00001)and overall survival(HR=0.70,95%CI:0.57-0.88,P=0.002)in treatment group were significantly longer than those in control group.There was no significant difference in complete response between two groups(RR=3.31,95%CI:0.41-26.89,P=0.26).The partial response in treatment group was significantly higher than that in control group(RR=15.97,95%CI:3.48-73.17,P=0.0004).The incidence of TKI-related adverse reactions above grade 3 in treatment group was significantly higher than that in control group(RR=2.91,95%CI:1.70-4.96,P<0.0001).Conclusion TKI can significantly prolong progress free survive and overall survival in patients with RAI-rDTC,but there are still many adverse reactions.It is necessary to comprehensively evaluate the health status of patients before medication.
