ABSTRACT
Objective To analyze the effect of transvaginal total hysterectomy under combined spinal epidural anesthesia. Methods From December 2015 to December 2016, in Longde people's hospital 80 cases underwent transvaginal total hysterectomywere randomly divided into two groups, he observation group and the control group. The control group was treated with continuous epidural anesthesia, the observation group were given combined spinal epidural anesthesia. The anesthesia effect and VAS scores were observed and compared. Results The excellent rate of anesthesia in the observation group was 95%, which was significantly higher than 75% in the control group(P<0.05). 1h after anesthesia, there was no statistically significant difference in the cough and static state VAS scores between the 2 groups; 6 and 12 hours after anesthesia, the cough and static state VAS scores was significantly better than those in the control group(P<0.05). Conclusion Compared with epidural anesthesia, combined spinal epidural anesthesia for vaginal total hysterectomy has a better anesthetic and analgesic effect, anesthesia safety is high, it is worthy of clinical application.
ABSTRACT
Objective To explore the difference and clinical effect in pediatric regional anesthesia with ketamine and fentanyl.MethodsThe clinical data of 60 cases of children with surgical treatment from June 2014 to December 2015 in Longde People's Hospital were retrospectively analyzed and randomly divided into two groups,with 30 cases in each group.The control group was given simple ketamine anesthesia;The intervention group was given ketamine combined with fentanyl anesthesia, of children with breathing,After anesthesia,the heart rate, respiratory,arterial pressure and other indicators and the anesthetic effect of the two groups were comprehensively evaluated.ResultsIn the intervention group after anesthesia, heart rate, respiratory rate, mean arterial pressure and pulse oxygen saturation was significantly better than the control group, there was statistical significance (P<0.05);and wake-up time in the intervention group, the dosage of ketamine and ketamine bolus times was significantly lower than the control group,there was statistical significance (P<0.05).ConclusionThe regional anesthesia operation were given ketamine and fentanyl assisted anesthesia, can stabilize children's heart rate, respiratory rate, shorten postoperative awake time, reduce anesthetic dosage, higher safety, anesthetic effect, can be widely applied in clinical.
ABSTRACT
Objective To investigate the apoptosis mechanism induced by BH3 mimetic S1 in human leukemia cell line K562.Methods Cell viability was detected by XTT to S1 in leukemia cell line K562.K562 cells was incubated with S1 for different time,the apoptosis rate of K562 cells was determined by flow cytometry analysis.Caspase-3,-8,and-9 activities were measured by absorption spectra.Co-immunoprecipitation was used to analyze the releasing of bax,bak from bcl-2 and mcl-1.Results Compared with control group,a dose-dependent increase in apoptosis coincided with a dose-dependent decrease in cell viability following S1 treatment suggested that S1 inhibits cell proliferation through the induction of apoptosis.The IC50 value at 24 h for S1 was 13.5 μ mol/L.Exposure of K562 cells to S1 for 12 h resulted in a time-dependent increase in FITC-Annexin-positive/PI-negative early apoptotic cells.The strong increase of FITC Annexin/PI doublepositive cells after a 24 h treatment indicated a shift to late apoptosis.S1 activated Caspase-3 and-9,but not Caspase-8 indicated that S1 induced K562 cells apoptosis via the intrinsic pathway.K562 cells treated with 5 μmol/L of S1 showed a disruption in bcl-2/bax,mcl-1/bak complexes after 8 h S1 treatment.Conclusion The main mechanism that S1 induces K562 cells apoptosis might be through the inhibition of bcl-2/bax,mcl-1/bak complexes dissociation.
ABSTRACT
Objective To evaluate the protective effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) in mice. Methods Thirty C57BL/6 mice were randomly divided into 3 groups: sham-operated (SO) group, I/R group (mice were injected with 5 ml/kg saline by tail vein just before ischemia induction) and hydrogen-rich saline group (mice were injected with 5 ml/kg hydrogen-rich saline). At the 6th h after reperfusion, the sera and renal samples subject to IR injury were collected. The Scr and BUN levels in serum were determined and renal histological changes were also examined. The apoptosis of renal tubular epithelial cells was measured by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay. Malondialdehyde (MDA) contents in renal samples were measured using specific kits. The infiltration of F4/80 positive macrophages and neutrophils was assayed by using immunohistochemistry. The mRNA expression of TNF-α, IL-6, IL-1β and IL-17 was detected by using real time reverse transcription PCR. Results As compared with LR group, at the 6th h following reperfusion the levels of Scr and BUN were significantly reduced (P<0.05), histological changes obviously alleviated (P<0.01), apoptosis of renal tubular epithelial cells and MDA contents was decreased (P<0.05) in hydrogen-rich saline group. Moreover, the infiltration of macrophages and neutrophils, and the mRNA expression of TNF-α, IL-6, IL-1β and IL-17 in renal tissue in hydrogen-rich saline group were also declined as compared with IR group (P<0.05). Conclusion Hydrogen-rich saline can ameliorate renal IR injury to some extent, which is associated with inhibition of inflammatory response induced by reperfusion.
ABSTRACT
Objective To observe the results of crown lengthening surgery on the teeth with subgingival defect.Methods Crown lengthening surgery was performed on 54 terior teeth,which were divided into two groups based on probing depth of pre-operation:group A (<3 mm) and group B (3-4 mm).All teeth were restored 8 weeks after operation and followed-up to 1 year.The parameters of plaque index (PLI),suleus bleeding index (SBI),maximal defect probing depth (PD) and mobility degree (MD) at different times were measured,respectively.Results PLI,BI and PD were significantly improved during the follow-up period (P<0.01).The success rates of both groups were 96.8% and 69.6%, respectively (P<0.01).No significant difference about MD in the group A one year after restoration (P>0.05),but a significant improvement in the group B (P<0.01).Conclusion Crown lengthening surgery is a good method on the teeth with subgingival defect,but one must select the right indication.

ABSTRACT
Objective To observe the application effect of wuhuangyou in the prevention of radiodermatitis for tumor patients undergoing chemotherapy and evaluate its applicability. Methods We divided 203 tumor patients undergoing chemotherapy into 3 groups.Application of wuhuangyou,meibao and routine health education were used in each group. Results Statistical difference existed in the incidence rate and degree of radio-dermatitis between the three groups,among which wuhuangyou proved to possess the best effect,P ＜ 0.01. Conclusion The application of wuhuangyou was safe,effective,economical in the prevention of radio-dermatitis.It could relieve the pain of patients and guarantee the smooth process of chemotherapy.
