Objective:To explore the clinical efficacy of Paishi granules on promoting stone expulsion after extracorporeal shock wave lithotripsy ( ESWL) . Methods:A retrospective study method was adopted. Totally 510 cases of lithangiuria patients were divided into the treatment group and the control group with 255 cases in each. The control group was treated by ESWL, and the treatment group was treated by Paishi granules after ESWL. The stone expulsion rate,clinical efficacy and adverse reactions in the two groups were stud-ied and compared. Results:The stone expulsion rate of the observation group was 78. 8%,which was significantly higher than that of the control group (51. 0%, P<0. 05). The curative rate of the observation group was 72. 9% with the total effective rate of 92. 5%, that of the control group was 43. 9% with the total efficiency of 82. 4%,and the differences between the two groups were statistically significant (P<0. 05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0. 05). Conclusion:Using Paishi granules after ESWL can promote stone expulsion with high efficacy and slight adverse reactions.

Objective To evaluate the effects of gender on the median effective target plasma concentration (EC50) of propofol inhibiting responses to laryngeal mask airway (LMA) insertion in patients.Methods Fiftyfive ASA physical status Ⅰ or Ⅱ patients,aged 20-60 yr,with body mass index 18-25 kg/m2,requiring LAM insertion,undergoing elective surgery,were divided into 2 groups according to the gender:male group (group M,n =27) and female group (group F,n =28).Propofol was given by target-controlled infusion.Anesthesia was induced with target-controlled infusion of propofol.The concentration of propofol was determined by using modified Dixon's up-and-down method.The initial target plasma concentration of propofol was 3.0 μg/ml (group M) or 2.7μg/ml (group F) and the ratio between the 2 successive concentrations was 1.1.Fentanyl 1 μg/kg was injected intravenously at about 10 min of propofol target-controlled infusion.LMA was inserted after the effect-site and plasma concentrations were balanced.The positive response to LMA insertion was defined as development of swallowing,coughing,biting LMA,body movement and laryngospasm during insertion.When the response to LMA insertion was positive,the concentration of propofol was increased in the next patient and when the response was negative,the concentration was decreased in the next patient.The EC50 and 95 ％ confidence interval of propofol inhibiting responses to LMA insertion were calculated.Results The EC50 (95 ％ confidence interval) of propofol was 3.11 (2.92-3.30) μg/ml in group F and 2.70 (2.55-2.85) μg/ml in group M (/ ＜ 0.05).Conclusion The EC50 of propofol inhibiting responses to LMA insertion is higher in female patients than in male patients.

5-Fluorouracil(5-FU)has been widely used to treat gastrointestinal,head,neck,chest and ovarian malignant tu-mors since 1957. As an analogue of pyrimidine,5-FU plays anti-cancer roles by inhibiting thymioylate synthase and integrating its me-tabolites into DNA and RNA. Although 5-FU is one of the first-line therapeutic compounds for gastrointestinal malignant tumor as a sin-gle drug or in combination with other drugs,its effectiveness is hindered by its low efficiency,which may be due to chemotherapy re-sistance. 5-FU chemotherapy resistance may stem from enzyme abnormality,genetic abnormality and tumor microenvironment. In this paper,we make a review about 5-FU actions and the mechanisms underlying chemotherapy resistance.

Objective To investigate the protective effects of ursolic acid (UA) on global cerebral ischemic-reperfusion injury in rats.MethodsThe experimental rats were divided into the sham operation group, the model group, the UA low, medium and high dose groups, 20 in each group. Except the rats in the sham operation group, the rats in other groups were dealed by four arteries occlusion to made global cerebral ischemia-reperfusion model. The rats in the UA low, medium, high dose groups were given UA as 40, 80, 120 mg/kg immediately after the occlusion line was inserted; the rats in the sham operation group and the model group were given equal-volume saline. And 6 hours later, the recovery time of righting reflex and electrical activity of brain were recorded, water content of the brain were evaluated, and the activity of LDH, MDA, SOD, CAT in brain tissue were determined; the inflammatory cytokines content of TNF-α, IL-1β, IL-6 were determined by ELISA. Results Compared with the model group, the recovery time of righting reflex (20.6 ± 7.2 min, 18.2 ± 6.9 min vs. 27.3 ± 8.8 min) and electrical activity of brain (16.2 ± 5.8 min, 14.9 ± 5.6 min vs.24.1 ± 7.2 min) of the UA medium and high dose groups were shortened (P<0.05 orP<0.01); the water content were significantly decreased (79.0% ± 0.7%, 78.6% ± 0.5%vs. 80.7% ± 0.9%;P<0.05 orP<0.01); the activity of SOD (158.5 ± 8.4 U/mg, 165.4 ± 9.0 U/mgvs. 143.0 ± 7.1 U/mg), CAT (3.3 ± 1.4 U/mg, 3.9 ± 1.5 U/mgvs. 2.4 ± 0.9 U/mg) in brain tissue of the UA medium and the high dose groups were significantly improved; the content of LDH (16.0 ± 2.6 mmol/g, 18.4 ± 2.8 mmol/gvs. 12.4 ± 1.9 mmol/g) were significantly increased; the content of MDA (18.6 ± 2.8μmol/g, 17.2 ± 2.4μmol/gvs. 24.9 ± 3.4μmol/g), TNF-α (45.8 ± 6.3 nmol/L, 40.1 ± 5.6 nmol/Lvs. 56.3 ± 7.2 nmol/L), IL-6 (187.2 ± 18.5 nmol/L, 136.8 ± 15.7 nmol/Lvs. 238.4 ± 22.9 nmol/L) were significantly decreased, and the content of IL-1β in UA 120 mg/kg treated group was significantly decreased (713.6 ± 56.3 nmol/L vs. 915.7 ± 70.5 nmol/L;P<0.05 orP<0.01).Conclusion UA can effectively promote righting reflex and EEG recovery, reduce brain water content, which perhaps related with its pharmacological effects of enhanceing the activity of antioxidant enzymes, lower oxidative stress, and inhibit inflammation.

Construc-tion of CSSD should be standard,so as to ensure the effectiveness of clean,disinfection and sterilization of surgical instruments.

Objective To evaluate the changes of hepatic blood perfusion of liver cirrhosis patients and the role of pericardial devascularization (PCDV)on them.Methods Hepatic artery and portal vein perfusions of 22 liver cirrhotic patients (LC) pre and post P CDV compared with control were evaluated with rheohepatogram(RHG) and ultrasonogram(USG).Results Compared with control,both hepatic and portal effective perfusion of LC were decreased on RHG, PCDV could increase portal perfusion of LC patients without significant effect on hepatic artery.USG showed that portal vein diameter and blood quantity of LC increased and PCDV didn't influence liver perfusion;No correlation between RHG and USG parameters were seen by STATA analysis. Conclusions RHG is an effective way to evaluate comprehensive blood perfusion of cirrhotic livers,the effect of operation on blood perfusion and prognosis.

BACKGROUND:For patients with lumbar spondylolisthesis combined with osteoporosis, appropriate fixation system for effective reset and good fixation stability is currently a hot issue of clinical concern. Pedicle screw screw-rod system after bone cement perfusion can achieve the effective fixation between pedicle screw system and the vertebral bone. OBJECTIVE:To observe the therapeutic effect of bone cement-augmented pedicle screw on patients with lumbar spondylolisthesis combined with osteoporosis. METHODS:17 cases of lumbar spondylolisthesis combined with osteoporosis were identified by bone density test. They received the posterior open reduction and internal fixation, and implanted with 68 bone cement-augmented pedicle screws. Their repair effects were observed by short-term fol ow-up. Patients were evaluated using low back pain Visual Analog Scale and lower limb Oswestry Disability Index before treatment, 1 week, 3 months and 1 year after treatment. Vertebral height, intervertebral height, screw loosening and bone cement leakage were observed using imaging.
RESULTS AND CONCLUSION:Compared with pre-treatment, low back pain Visual Analog Scale score and lower limb Oswestry Disability Index were significantly improved at 1 week, 3 months and 1 year after treatment (P<0.05). No significant difference was detected between post-treatment and fol ow-up (P>0.05), which indicated that clinical repair effect could be effectively maintained. At 3 months of fol ow-up, one screw loosening occurred in two patients. During fixation, mild bone cement leakage appeared in seven vertebral bodies with screw fixation, no symptoms or subsequent complications were observed. There were no significant differences in vertebral height and intervertebral height before and after treatment and during fol ow-up (P>0.05). These results suggest that bone cement-augmented pedicle screw for patients with lumbar spondylolisthesis combined with osteoporosis can effectively reset vertebral slippage, effectively provide good anti-pul-out force for a long term, and the effect was stable. Bone cement augmentation can perfectly strengthen fixation, shows good biocompatibility, and avoids osteoporosis around the screw-induced failure fixation.
