Objective To investigate the efficacy of metholrexate combined with rmifepristone and laparoscopic surgery for treating ectopic pregnancy.Methods 85 patient with ectopic pregnancy were selected.41 cases treated with methotrexate and mifeprisione were considered as the control group,while 44 cases with laparoscopic surgery were considered as the observalion group on the voluntary basis.The clinical efficacy,serum β-HCG value and recovery time after 7d were compared between the two groups.Results After the treatment,the cure rate in the observation group was 100％ which was significantly higher than 90％ of the control group ( P ＜ 0.05 ),the serum β-HCG value of the observation group was lower and the restoration normal time was shorter than the control group ( P ＜0.05).Conclusions Laparoscopic surgery and conservative treatment of methotrexate combined with mifepristone are effective in the treatment of ectopic pregnancy.However,the clinical efficacy of the laparoscopic surgery is better and it has rapid recovery time,and it can completely cure the patients.

[ABSTRACT]AIM:ToobservetheeffectofthesignalingpathwayofproteinkinaseC(PKC)-nuclearfactor-ery-throid 2-related factor 2 (Nrf2) on the expression of heme oxygenase-1 (HO-1) induced by cigarette smoke extract (CSE) in the rat airway epithelial cells .METHODS:After exposed to CSE , the airway epithelial cells of male SD rats were di-vided into control group , CSE3 group, RO318220 group, Nrf2 siRNA group and RO318220+Nrf2 siRNA group.The pro-tein levels of HO-1, Nrf2 and PKC were semi-quantified by Western blotting .The protein expression of HO-1 was assessed by immunocytochemistry .The mRNA expression of HO-1 was detected by reverse transcription-polymerase chain reaction ( RT-PCR) .Nrf2 protein location was observed by immunofluorescence staining .HO-1 activity was also determined .RE-SULTS:After exposure to CSE for 3 h, the Nrf2 protein was mainly located in the nucleus , and the expression level of Nrf2 protein in the nucleus was stronger than that in the control cells .CSE also significantly enhanced the levels of p-PKC protein, and HO-1 mRNA, protein and activity .Pretreatment with RO318220 significantly decreased the levels of PKC pro-tein, Nrf2 protein, and HO-1 mRNA, protein and activity.Meanwhile, Nrf2 protein significantly decreased , and the activ-ity, mRNA and protein levels of HO-1 were also significantly attenuated by pretreatment with siRNA to knock down Nrf2. Pretreatment with RO318220 and Nrf2 siRNA significantly decreased the PKC protein , Nrf2 protein, and HO-1 mRNA, protein and activity .CONCLUSION:CSE up-regulates the HO-1 expression through PKC-induced nuclear translocation of Nrf2 in the rat airway epithelial cells .

Objective:To observe the effect of the signaling pathway of protein kinase C (PKC)-nuclear factor-erythroid 2-related factor 2 (Nrf2) on the expression of heme oxygenase -1 (HO-1) induced by cigarette smoke extract in rat airway epithelial cells.Methods:The airway epithelial cells of 25 male SD rats were randomly divided into a control group, a CSE3h group, a RO318220 group (PKC inhibitor), a Nrf2 siRNA group and a Nrf2 siRNA+RO318220 group, 5 rats in each group. hTe control group was incubated with DMEM/F12 alone. hTe CSE3h group was treated with 10% CSE for 3 h. hTe RO318220 group was pretreated with 3 μmol/L RO318220 for 0.5 h and subsequently treated with 10% CSE for 3 h. hTe Nrf2 siRNA group was pretreated with Nrf2 siRNA, and then treated with 10% CSE for 3 h. hTe Nrf2 siRNA+RO318220 group was pretreated with Nrf2 siRNA and 3 μmol/L RO318220 for 0.5 h, and then treated with 10% CSE for 3 h. hTe protein levels of Nrf2 in the nucleus and cytoplasm, and HO-1 and PKC in the whole cells were semi-quantified by Western blot. The protein expression of HO-1 was measured by immunocytochemistry. HO-1 mRNA expression was detected by RT-PCR. Immunolfuorescence staining was used to observe the nuclear translocatin of Nrf2. Results: CSE markedly induced Nrf2 nuclear translocation in the rat airway epithelial cells, and RO318220 pretreatment blocked the CSE induced Nrf2 nuclear translocation. Immunocytochemistry showed that HO-1 protein expression was strongly positive in the CSE3h group, weakly positive in the other 4 groups. hTe expression of PKC protein, HO-1 mRNA and protein signiifcantly increased in the CSE3h group, and HO-1 activity markedly improved in the CSE group (P<0.05). hTe level of PKC protein expression was not signiifcantly different in the Nrf2 siRNA group compared with that in the CSE3h group (P>0.05). Conclusion: CSE induces the nuclear translocation of Nrf2 by PKC signaling pathway, thus upregulating the HO-1 expression in the rat airway epithelial cells.

An artificial liver support system (ALSS) is a body circulatory system aims to blood purification, which consists of plasma exchange, hemodialysis, hemoperfusion, in combination with hemodiafiltration. The clinical application of non-biological artificial liver, especially plasma exchange technology, can solve the problem such as hyperbilirubinemia, endotoxemia, toxic substance accumulation and disorder of amino acid metabolism, which would save patients’ lives. ALSS can significantly improve the general physical condition, reduce operative risk, as well as relieve physiologic derangement after liver transplantation. Therefore, artificial liver serves as a bridge for liver transplantation. This paper analyzes the characteristics of ALSS, explores the methods of ALSS application in perioperative period of liver transplantation, and discusses its developing orientation.

OBJECTIVETo observe the difference in the therapeutic effects on knee osteoarthritis (KOA) among auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste (combined therapy), electroacupuncture (EA) and TDP irradiation.

METHODSEighty-nine cases were randomized into three groups. In the combined therapy group (30 cases), the auricular electroacupuncture therapy was adopted together with the isolated moxibustion with Lingxian herbal paste. The auricular points were xi (AH4), pizhixia (AT4), shenmen (TF4), etc. The Lingxian herbal paste was applied at Yanglingquan (GB 34), Dubi (ST 35), Zusanli (ST 36), Neixiyan (EX-LE 4), Heding (EX-LE 2) and Ashi points. In EA group (29 cases), EA was applied at the acupoints that were same as those in the isolated moxibustion with Lingxian herbal paste. In TDP group (30 cases), TDP irradiation was given at the affected knee. The treatment was given once every day, 10 treatments made one session and there was 1 week at the interval among sessions. Totally, 3 sessions of treatment were required. KOA clinical symptom and physical sign score and the single item pain symptom score of Lequesne index were observed before treatment and 1 week after treatment in the patients of each group separately. The efficacies were compared among the three groups.

RESULTSOne week after treatment, the total score of symptoms and physical signs of the patients in each group was reduced significantly as compared with that before treatment (all P < 0.05). The improvements in the symptoms and physical signs in the combined therapy group were better than those in the other two groups (1.50 +/- 1.57 vs 2.52 +/- 1.82, 2.63 +/- 1.97, both P < 0.05). The improvement in pain in the combined therapy group was also better than that in the other two groups (2.37 +/- 0.81 vs 2.83 +/- 0.92, P < 0.05; 2.37 +/- 0.81 vs 3.03 +/- 0.77, P < 0.01). The curative rate in the combined therapy group was 40.0% (12/30), which was higher than 17.2% (5/29) in EA group and 20.0% (6/30) in TDP group separately (both P < 0.01). The overall efficacy in the combined therapy group was superior to the other two groups (P < 0.05).

CONCLUSIONThe auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste is advantageous at the total score of the symptoms and physical signs and the overall efficacy in the patients of KOA as compared with EA at the local acupoints and local TDP irradiation.
