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.

Tacrolimus is an widely used immunosuppressant in organ transplant patients for anti-rejection,and the quality of life and survival rate are greatly enhanced.At present,a growing number of scholars concerned with drug interactions of Western medicine and tacrolimus.However,the impact of planta medica on it was rarely systematically overviewed.This article explored the interaction of planta medica and tacrolimus.

Malnutrition is one of the most important factors for the prognosis of patients with gastric cancer,but the mechanism of malnutrition is unclear at present. These patients are at risk of nutritional deple-tion from anorexia,dysphagia,and may be associated with the presence of two or more of the following cyto-kines with metabolic activity such as TNF-α,IL-1,IL-6,interferon,leptin,nuclear factor-κB and so on, which are secreted by the host-tumor interaction. The cytokines constitute a sophisticated regulatory network. Therefore,the study of the relationship between malnutrition and related factors in patients with gastric cancer may improve the nutritional status and prognosis of these patients.

Objective To detect the serum estrogen level in women with involution al depression (ID) and to study the effect of estrogen on the occurrence of ID. Methods Serum estrogen levels at 7:00 am were detec ted by r adioimmunoassay in 40 normal menopausal women (Group A) and 49 cases of ID (Grou p B), and compared with those of 36 cases previously detected. Results Estro gen level was much lower in Group B than Group A (P 0.05 ). Co nclusion The occurrence of ID in menopausal women may be related to t he decrease of estrogen level, but the specific correlation of the above two has not been proved yet.

Objective To investigate the effectiveness of microresection combined with radiofrequency ablation under laryngoscope and rigid telescope for laryngeal precancerosis. Methods Fifty-one patients with laryngeal precancerosis, which was diagnosed pathologically, were treated with microresection combined with radiofrequency ablation under laryngoscope and rigid telescope. The patients were followed up for over 6 months. Results During a mean of 26-month follow-up (6 months to 4.5 years), 7 of the patients had recurrence (vocal cord leukoplakia in 3, atypical hyperplasia in 2, and laryngeal papilloma in 2); 4 had carcinomatous change (vocal cord leukoplakia in 1, atypical hyperplasia in 2, and laryngeal papilloma in 1);and 2 patients developed laryngeal web after surgical treatment for bilateral vocal cord leukoplakia. One month after the operation, the Jitter, Shimmer, and NNE were decreased significantly (P

Objective To investigate the method of constructing bioartificial renal tubule assist device(RAD) and its transport function to creatinine,glucose,sodium and asparagine,theonine,serine,glutamic acid in vitro.Methods The cultured LLC PK1 cells were seeded into the inner space of the hemofilter(FH66)and the hemofilter was incubated for two weeks.Then the filtration in vitro was simulated to detect the function of the RAD.The transport rates of sodium,creatinine,glucose and four kinds of amino acids were measured.Meanwhile,the effects of oubaine and phlorizin on the transport rates of sodium,glucose and amino acids were determined and compared with no LLC PK1 device.Results The creatinine transport rate of RAD was significantly decreased as compared with control group(P

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.

Objective To explore effect of different withdrawal time of dexmedetomidine (DEX) on the quality of general anesthesia recovery.Methods Eighty patients of ASA Ⅰ or Ⅱ undergoing lymph surgery were randomly assigned to four groups (n =20).Groups D1,D2 and D3 received DEX 0.5 μg/kg as bolus before induction,continued with 0.5 μg/(kg · h) by infusion until one hour,30 min before the end of operation and the end of operation,respectively.Group C received equal volume of normal saline.Mean artery pressure (MAP),heart rate (HR) and pulse oxygen saturation (SpO2) were observed during and after operation.Spontaneous respiration recovery time,eyes open time,extubation time,orientation recovery time,observer's assessment of alertness/sedation score (OAA/S),restlessness score (RS),and visual analogue scales (VAS) were observed after operation.Results For MAP and HR in Groups D2 and D3,there were no statistically significant difference during extubation compared to those at preoperation,but at the same time point,they were lower than those in group C (P ＜ 0.05).For groups C and D1,MAP and HR at extubation and 5 min after extubation were higher than those at preoperation (P ＜0.05).Spontaneous respiration recovery time,eyes open time,extubation time,orientation recovery time in group D3 were significantly longer than those in Group C (P ＜ 0.05),while there were no statistically significantly difference between groups D1,D2,and group C.OAA/S in group D3 was significantly lower than that in group C (P ＜ 0.05) at extubation.Incidence of restlessness,VAS,and cases given analgesic 2 hours after operation in groups D2 and D3 were significantly lower than those in groups C and D1.Compared to those in group C,dosages of propofol and remifentanil in groups D2 and D3 were significantly lower.Conclusions Dexmedetomidine administered of 0.5 μg/kg before induction,continued with infusion of 0.5 μg/(kg · h) until 30 min before the end of operation,may improve emergence,without influencing the awakening time of patients,and prolong the duration time of analgesia which comfort the patients.

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.
