ABSTRACT
Objective To compare the effectiveness and safety of ultramini percutaneous nephrolithotomy (UMP) and retrograde intrarenal surgery (RIRS) in treatment of moderate-sized (about 1-2 cm) renal lower caliceal calculi.Methods From March 2015 to December 2016,patients in our hospital scheduled for surgery due to renal lower caliceal calculi with the greatest diameter of 10-22 mm were prospectively analyzed.Patients were randomized into two groups according to the random number table.Group UMP's operational channel was only F14 and the nephroscope's diameter was 1 mm.200 μm holmium laser lithotripsy was used to break the stones which was rushed out by eddy cuurent.In Group RIRS,all patients needed placing a F6 double J stent preoperatively for two weeks.A flexible ureteroscope sheath required imbedding intraoperatively.The stones were smashed by 200 μm holmium laser lithotripsy through the WOLF flexible ureteroscope.The intraoperative and postoperative datas including stone-free status and the complications were compared.Results 100 patients were enrolled in the study 50 patients in Group UMP,28 were male and 22 were female,mean age was 43.4 ± 7.9 years old.Mean stone size was 14.5 ±3.0 mm(range 10-22 mm).Among them,18 cases were complicated with mild and moderate hydronephrosis.The other 50 cases were allocated to Group RIRS,including 31 males and 19 females.Their mean age was 44.5 ± 8.3 years old and mean stone size was 13.7 ± 3.1 mm (range 10-21 mm).Among them,16 cases were complicated with mild and moderate hydronephrosis.No statistically significant difference were seen between the two groups (P ＞ 0.05).After three months' follow-up,one-time stone free rate(SFR) of UMP group was 94.0％ (47/50),which was significantly more superior than the 72.0％ (36/50) of the RIRS group(P ＜ 0.05).The intraoperative decrease in hemoglobin were (7.8 ± 3.3) g/L vs.(3.1 ± 3.4) g/L,and operating time(26.5 ± 6.1) min vs.(43.3 ± 6.3) min.Significant differences were also seen between the two groups(P ＜0.05).There was more blood loss and less operating time in the group of UMP.The hospital stay,delayed hemorrhage and postoperative fever between the UMP and RIRS groups were (4.3±1.3)d vs.(3.24 ± 1.21)d,8.0％ (4/50)vs.0(0/50),16.0％ (8/50)vs.12.0％ (6/50) respectively.No significant differences were seen (P ＞ 0.05).Conclusions Both UMP and RIRS procedures are effective and safe in the treatment of moderate-sized renal lower caliceal calculi.Compared with RIRS,UMP may be more effective and has less operating time,however wtih more intraoperative blood loss.
ABSTRACT
Objective To study the clinical effect of remifentanil intravenous patient-controlled analgesia pump combined with psychological intervention in labor analgesia.Methods 100 cases of maternal in our hospital from April 2015 to July 2016 were selected as the research object in this study.They were randomly divided into the control group and the experimental group, each group had a total of 50 cases.Patients in the control group were treated with intravenous patient-controlled analgesia pump, while the experimental group received psychological intervention on the basis of remifentanil treatment.The anxiety, pain and cesarean section were compared between the experimental group and the control group.Results After the corresponding treatment, the experimental group of 50 patients, the number of cases of cesarean section in 6 cases, the rate of cesarean section was 12%, in the control group of patients with a total of 50 cases, the number of cases of cesarean section in patients with cesarean section rate of 28%.But the control group was significantly higher than that of the experimental group, the difference was statistically significant(P<0.05).The visual analogue score of the experimental group was significantly lower than that of the control group, with statistical difference(P<0.05).The incidence of adverse reactions in the experimental group was 18%, and the incidence of adverse reactions in the control group was 14%.The number of patients with moderate anxiety in the control group was significantly higher than that in the experimental group, with statistical difference(P<0.05).Conclusion Remifentanil intravenous analgesia pump combined with psychological intervention for clinical effect of labor analgesia is better, can effectively eliminate the anxiety of patients, relieve pain, and high safety, is further applied in clinical significance.
ABSTRACT
In recent years,due to the impact of marked-oriented economy,the scale of the magazine and the demand of the readers of some Medical Abstracts Journals was tending to decrease year by year,as well as the publication was facing difficulties.This article discussed on how to revitalize the Medical Journal Abstracts.It proposed that the Abstracts Journals should pinpoint the orientation,embody the characters,and take the development of individualization.
ABSTRACT
AIM: To investigate the antidysmsenorrhea pharmacologic effects of Compound Yimucao Paste (Herba Leonuri, Rhizoma chuanxiong, Radix Angelicae Sinensis, Flos Carthami) METHODS: The methods of microcirculation and isolated uterus smooth muscle of rat were used. RESULTS: Compound Yimucao Paste could improve the microcirculation disturbance on the aspects of the diameter, the velocity of mice auricle microarterioles and microveins, inhibit the isolated uterus smooth muscle contraction and mouse twister induced by oxytocin. CONCLUSION:Compound Yimucao Paste has an obvious action of blood quickening and stasis transforming and inhibit the isolate and uterus smooth muscle contraction induced by oxytocin, which are contributed to its antidysmenorrhea effect.

ABSTRACT
Phloroglucinol is an antineoplastic effective compound from Dryopteria Crassirhizoma Nakai. In this study, mice implanted with leukemia P388 were examined under an electron microscope. It' was found that the leukemia bearing mice, which had been injected with phloroglucinol exhibited degeneration and swelling of mitochondria in the P38'8 cells. Measurement with an oxygen electrode showed that the drug treatment of P388 cells markedly lowered their oxygen consumption in comparison with the control cells .The results demonstrate that phloroglucinol inhibits respiration of tumor cells. Probably, the mitochondria of tumor cells is a target that the drug attacks.
ABSTRACT
Objective To observe the molecular weight distribution of soybean peptides prepared by complex enzyme hydrolysation and tumor inhibitory effect in vivo or in vitro. Method The soybean protein was enzymolyzed to soybean peptides by Flavourzyme, Alealase and neutral protease, at(50-55)℃, followed by separation, absorption,affination, ultra centrifuge and spray drying. The soybean peptides were passed Sephadex G25 column at 0.5ml/min with 0.1mol/L Tris-HCl buffer. The fragment of fluid collected was determined by UV at 280nm and HPLC. Then the molecular weight distribution was calculated. The inhibitory effect on ansplant glioma (G422) at dose 1.25, 2.5 and 5g/kg bw (ig daily for 11 d) was tested in mice and in Hep-2 in vitro. Results The peptides contents in three batches were 54.6%, 51.9%, 51.8% respeclively. The molecular weight
