3.Comparison of retrograde intra-renal surgery and percutaneous nephrolithotomy in treating renal pelvic stone less than 1 .5 centimeters
Journal of Clinical Surgery 2015;(2):113-115
Objective To explore the best minimal invasive method in treating renal pelvic stones less than 1.5 cm.Methods A total of 90 patients with renal pelvic stone less than 1.5 cm were enrolled, including 47 cases of retrograde intrarenal surgery(RIRS)by rigid and flexible ureteroscopy with holmium laser lithotripsy,and 43 cases of percutaneous nephrolithotomy(PCNL)by holmium laser lithotripsy.Opera-tion time,stonefree rate(SFR),hospitalization,and complications were analyzed for comparison.Results The average sizes of stone in the RIRS group and PCNL group were 1.2 cm(range 1.0 ~1.5 cm)and 1.3 cm (1.0 ~1.5 cm),respectively.In the RIRS group,45(95.74%)patients out of 47 had complete clearance and 32 patients needed combination of flexible ureteroscopy to fragmentate the stones falling into the renal calices.The operation time was 44 min(range 27 ~70 min)with postoperative fever in 2 cases.The decrea-sing in hemoglobin and hematocrit was(0.18 ±0.06)g/L and 0.11%,respectively.No major complication was recorded.In PCNL group,the mean operation time was 70min(range 45 ~90 min)with a stone-free rate of 95.35%(41 /43).The decreasing in hemoglobin and hematocrit was(17.25 ±6.70)g/L and 5. 62%,respectively.The complications in PCNL group were postoperative fever in two cases and bleeding in two cases.Conclusion RIRS has the advantages of natural orifice endoscopic surgery in shortening opera-tion time,reducing blood transfusion requirements,and decreasing postoperative complications.For renal pelvic stone less than 1.5 cm,RIRS can be the primary choice.
4.Comparison of root resorption between T loop technique and sliding technique of orthodontic treatment
Journal of Practical Stomatology 2015;(1):92-95
Objective:To Compare root resorption between T loop technique and sliding technique of orthodontic treatment.Meth-ods:90 patients with Angle class I malocclusion were orthodontically treated by MBT fixed appliances with T loop technique(n =45) and sliding technique(n =45)respectively.Root resorption of the patients were examined by grading evaluation method with orthopan-tomography and periapical films before and after orthodontic treatment.Results:After orthodontic treatment the tooth root resorption rate increased(P <0.05),the root resorption rate was not significantly different between T loop technique group and sliding technique group(P >0.05).Root resorption mostly occurred in the incisors,especially in mandibular tooth.Conclusion:There is no difference of the effect of root resorption between T loop technique and sliding technique of orthodontic treatment in patients with Angle class I malocclusion.
5.Effects of heroin use on serum levels of homocysteine
The Journal of Practical Medicine 2015;(9):1519-1521
Objective To determine whether concentrations of plasma homocysteine and status of folate and vitamin B12 were altered in patients with heroin dependence compared with control subjects. Methods We recruited 20 patients with heroin addiction. Twenty age-and sex-matched healthy volunteers as the control group were enrolled. Blood concentrations of homocysteine, folate and vitamin B12 were measured in a fasted status. Results Mean homocysteine level was higher in the heroindependence group than in the control group [18.3 ± 4.5 (Q1 = 14.7, Q2 = 17.6, Q3 = 19.2) vs. 8.4 ± 2.7 (Q1 = 5.9, Q2 = 8.5, Q3 = 10.5) μmol/L, P < 0.001]. Patients in heroinaddictiongroup had signi cantly lower folate levels compared with the control group [6.6 ± 2.6 (Q1=4.6, Q2=6.4, Q3=8.1) vs. 12.7 ± 2.5 (Q1 = 11.1, Q2 = 13.0, Q3 = 17.5) ng/mL, P < 0.001]. There was significant difference on plasma B12 concentrations between heroin users and controls [384.1 ± 228.8 (Q1=312.0, Q2=348.5, Q3=374.5) vs. 399.4 ± 45.1 (Q1=358.0, Q2=394.5, Q3=428.3) Pg/mL, P < 0.001]. Heroin users group demonstrated a negative correlation of homocysteine with folate , which was statistically significant in heroin users groups (r = - 0.614; P = 0.004), there was a trend towards a negative correlation of homocysteine with B12 in heroin users (r = -0.605; P = 0.005), respectively. Conclusions We conclude that patients with heroin dependence are prone to high concentration of plasma homocysteine.
6.Effect of Piribedil Combined with Madopar in the Treatment of Parkinson’ s Disease
China Pharmacist 2014;(5):806-807
Objective:To observe the clinical effect of piribedil and madopar on Parkinson's disease ( PD) . Methods:Totally 58 patients with PD were divided randomly into the treatment group (29 cases) and the control group (29 cases). Piribedil and madopar were used in the treatment group, while only madopar was applied in the control group. Therapeutic effect of both groups was evaluated by UPDRS at the end of 6 courses. Results:The decrease of UPDRS after the remedy in the treatment group was more significant than that in the control group (P<0. 05), and the total effective rate in the treatment group(89. 7%) was significantly higher than that in the control group(65. 5%)(P<0. 05). Conclusion:The clinical effect of piribedil combined with madopar on PD is superior to that of madopar alone, therefore, the combination use is a useful method in the treatment of PD with the value of popularization and applica-tion.
7.Concurrent chemoradiation for non-small cell lung cancer
Journal of International Oncology 2013;40(10):755-758
The standard non-surgery approach for locally advanced non-small cell lung cancer (NSCLC) is concurrent chemoradiotherapy.Common chemotherapy regimens include EP,NP,DC and PC.New chemotherapy drugs combination and targeted therapy are still under study.The tolerances of elderly patients are declining for concurrent chemoradiotherapy,but it is not the absolute contraindication.The tolerance for hyperfraction and high dose radiotherapy is well,however,the effectiveness and long-term toxicity need to be further studied and evaluated.
