ABSTRACT
Objective@#To study the therapy of cordyceps-astragalus-salvia miltiorrhiza in treating acute lung injury and pulmonary interstitial fibrosis induced by paraquat poisoning.@*Methods@#All 120 adult Wister male rats were randomly assigned to three groups, the paraquat poisoning group (rats were intragastric administration paraquat 50 mg/kg body weight once at the beginning) , the cordyceps-astragalus-salvia miltiorrhiza therapy group (rats were given cordyceps-astragalus-salvia miltiorrhiza 90 mg/kg body weight intragastric administration half an hour after paraquat was given, then the same dose was given once a day) ; control group (rats were intragastric administration with physiological saline) . At 7th, 14th, 21st, and 28th day rats were sacrificed postanesthetic respectively after paraquat exposure, sample of lung tissue, bronchoalveolar lavage (BAL) , and venous blood were collected. GSH, SOD, TNF-α, TGF-β1, and HYP in plasma, bronchoalveolar lavage (BAL) , and the lung homogenates were determined. Optical microscope was performed to examine pathological changes in lung.@*Results@#Each experimental time point paraquat group and the treatment group rats serum SOD content significantly lower than the control group (P<0.05) . Each experimental time point the treatment group rats serum SOD levels increased significantly than that of paraquat group (P<0.05) . Each experimental time point paraquat group rats serum GSH content significantly lower than that of the control group (P<0.05) . Treatment group rats 7 days time GSH content significantly lower than that of the control group (P<0.05) . Treatment group 21 days, 28 days GSH content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rats alveolar lavage SOD content was significantly lower than that of the control group (P<0.05) . Treatment group 7 days, 14 days time SOD content was significantly lower than that of the control group (P<0.05) , Treatment group 21 days, 28 days SOD content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group and the treatment group rats alveolar lavage GSH content significantly were lower than that of the control group (P<0.05) . Treatment group days 14 and 21 days, 28 days GSH content was increased significantly than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rats alveolar lavage TNF α levels was higher than that of the control group (P<0.05) . Treatment group 7 days, 14 days the rat alveolar lavage TNF α levels was higher than that of the control group (P<0.05) . Treatment group 21 days, 28 days TNF α content significantly was decreased than that of paraquat group (P<0.05) . Paraquat group days 14 and 21 days, 28 days HYP content was significantly higher than that of control group (P<0.05) . Treatment group 21 days HYP content was significantly higher than that of control group (P<0.05) . Treatment group 28 days time HYP content in lung tissue of rats was significantly decreased than that of the paraquat group (P<0.05) . Each experimental time point paraquat group rat lung tissue (tissue homogenate) TGF-β1 content was higher than that of the control group, the difference was statistically significant (P<0.05) . Under optical microscope, the tissue damage of lung was aggravated, and reduced after cordyceps-astragalus-salvia miltiorrhiza was administrated.@*Conclusion@#Cordyceps-astragalus-salvia miltiorrhiza can reduce inflammation factor releasing, and relieve lung injury. It has therapeutic effect on lung injury induced by paraquat poisoning.
ABSTRACT
Objective To investigate the incidence of genotypes related to analgesia and muscle relax effects,and to review the genetic polymorphism of OPRM1,CYP3A4 * 1G,SLCO1B1 and ABCB1 in Han population in North-western China.Methods The genotypes of OPRM1,CYP3A4 * 1G,SLCO1B1 and ABCB1 in patients born in North-western China between September,2016 and May,2017 were reviewed.North-western China was defined as Shaanxi,Gansu,Ningxia,Qinghai and Xinjiang Provinces.The distribution of genotypes was recorded.And the differences between male and female patients were compared.Results The frequency was 42.11％ for AG genotype and 12.14％ for GG genotype of OPRM1 (118A＞G).For CYP3A4 * 1G,the frequencies of CC,TT,TC and CT were 29.69％,4.17％,65.67％ and 0.47％,respectively.For ABCB1,the frequencies of CC,TT,TC and CT were 13.07％,44.60％,0.28％ and 42.05％,respectivsly.For SLCO1B1,AG genotype appeared in 37.44 ％ of the patients,GG genotype appeared in 55.21％ of the patients.There was no difference between the male and the female patients.Conclusion Genotypes related to change of susceptibility to opioids including fentanyl and rocuronium were detected in high percentage of patients in North-western China,indicating that SNP assay for instruction of anesthetic practice be of value.
ABSTRACT
Objective To explore the role of humall papillomavims (HPV) type 16 E6 variants in the persistent infection and recurrence of the cervical high-grade squamous intraepithelial lesion (HSIL) after conization. Motheds During May to June 2012, 100 HSIL patients with HPV16 positive but negative at the margin after Loop electrosurgical excision procedure (LEEP) were selected from Shanghai People′s Hospital of Pudong District. The gene sequencing was done to the E6. The patients were followed up for 2 years. The E6 gene sequencing was done again to detect the HPV16 variants among those with persistent infections and recurrence. Results Among the 100 cases, E6 variants were detected, 81% of them HPV E6 variants Asian prototype, 14% European variant; 2% European prototype (EP) and 3% African variant 1. LEEP for Asian prototype was susceptible to the clearance of HPV16 (P < 0.001). The European variants of T350G, and A442C were correlated with persistent infection and recurrence (P < 0.001). Conclusion The HPV16 variant is closely related to the HSIL incidence. HSIL caused by HPV16 in Pudong New Area of Shanghai belong to the Asian type variant. The European variants of E6 , T350G/A442C were likely related to the recurrence of HPV16.
