Objective To investigate the anesthetic action of intraperitoneal (i.p.) emulsified isoflurane and determine ED50 and LD50 in rats. Methods One hundred and thirty SD rats aged 6-8 weeks veighing 120-150 g were randomly divided into three groups: (A) control group ( n = 10) ; (B) ED50 group ( n = 60) ; (C) LDSO group (n = 60) . Group B and C were further divided into 6 subgroups with 10 animals (5 male, 5 female) in each subgroup. In control group a single bolus of 30% emulsified fat 2ml/100g body weight was administered i. p. In ED50 group a single bolus of 2.30% -6.0% vol/vol emulaified isoflurane 1.5 ml/100 g was administered i. p. and righting reflex was recorded. In LD50 group a single bolus of 4.09% - 10.64% vol/vol emulsified isoflurane 2 ml?100 g-1 was given i.p. and toxic response and lethal dose were recorded. The concentration ratio of the two neighbouring subgroups was 1:0.825. Results The ED50 of emulsified isoflurane was (0.57?0.07) ml.kg-1 and 95% confidence limit (CL) was (0.51-0.64)ml?kg-1 . The average onset time of action was (2.64 ?0.99) min and the average duration of action was (28 ? 11) min. The LD50 of emulsified isoflurane was (1. 26 ?0.10) ml?kg-1 and 95% confidence limit was 1.10-1.45 ml?kg-1 . The therapeutic index (LD50/ED50)was 2. 24. Conclusion Intraperitoneal emulsified isoflurane can provide effective general anesthesia and can be used for animal experiments which need anesthesia of short duration.

Methods Between Apr. 2006 and Jun. 2009,60 patients undergone curative treatment for HCC were enrolled in the retrospective analysis. Patients were assigned into four groups (15 each):patients in groupⅠ(serum HBV-DNA≥1.0?105copies/ml) and groupⅡ(serum HBV-DNA

Objective To evaluate the role of thoracoscopy-assisted mini-incision in surgical treatment of lung tuberculosis.Methods From 1999 to 2004,pulmonary lobectomy was performed with thoracoscopy-assisted mini-incision(5-7 cm) on 42 patients with lung tuberculosis(right superior lobectomy in 16,right middle lobectomy in 4,right inferior lobectomy in 4,left superior lobectomy in 10,left lingular lobectomy in 4,and left inferior lobectomy in 4).Results None of the patients were converted to open surgery.The mean operation time was 105 min(35-170 min);blood loss ranged 100-800 ml(mean,150 ml).In the patients,thoracic drainage lasted for 1-5 d(mean,2.8 d) after the operation,and the hospital stay was 4-11 d(mean,6.7 d).During a 2-to 13-month follow-up(mean,8.2),no patient showed positive sputum,bronchopleural fistula,or diffusion of tuberculosis.Conclusions Since thoracoscopy-assisted mini-incision is assosiated with minimal tissue injury,few blood loss,quick postoperative recovery,short hospital stay,and few complications after the surgical treatment of lung tuberculosis,it is worth being widely used.For surgeons,it is important to remember the indications for the procedure.

Objective To compare the short-term curative effects of prucalopride and mosapride respectively combined with low dose polyethylene glycol in treating elderly refractory functional constipation.Methods Ninety patients with elderly refractory functional constipation in the outpatient department of our hospital from May 2014 to February 2016 were retrospectively analyzed and divided into two groups randomly,45 cases in each group.the prucalopride group:Prucalopride Succinate Tablets,2mg,4 times daily;the mosapride group:Mosapride Citrate Capsules,5mg,3 times daily.Polyethylene Glycol Electrolytes Powder(PEG) was also used in the two groups,13.125g,twice daily.The course of treatment was 4 weeks.The first defecating time and defecation difficulty relief time,average weekly spontaneous complete bowel movements (SCBM),defecating difficulty,stool character,adverse reactions and change of life quality were observed in the two groups.Results The treatment effective rate of slow transit constipation(STC) and defecatory disorder had the statistical difference between the two groups (P<0.05).The comparison of the effective rates in mixed type showed no statistical difference between the two groups(P>0.05).Compared with the mosapride group,the first defecating time and defecation difficulty relief time in the prucalopride group were shorter with statistical difference (P<0.05).After 4-week treatment,SCBM times per week in the two groups were more than 3 times;the times of the prucalopride group were even more.In the prucalopride group,the defecation difficulty improvement was more obvious,the difference between the two groups had statistical significance (P<0.05).As for the comparison of the stool character improvement,the difference had no statistical significance(P>0.05).The total effective rate had statistical difference between the two groups(P<0.05).The incidence rate of adverse reactions had no statistical difference between the two groups(17.78% vs.15.56%,P<0.05).The total average score of PAC-QOL after treatment in the two groups were both decreased,moreover the decrease in the prucalopride group was more obvious;the difference between the two groups had statistical significance(P<0.05).Conclusion Prucalopride +PEG take effect faster in the treatment of elderly refractory functional constipation and has the advantages in the aspects of overall curative effect and life quality improvement,which is specially suitable for STC and defecatory disorder type.

Objective To investigate the levels of serum macrophage inflammatory protein-1α (MIP-1α),inflammatory factors and pulnonary function in patients with asthma,and the correlation between thenm.Methods Eighty patients with asthma were selected who were treated in our hospital from March 2015 to August 2016,and the data of 80 healthy adults were selected as control.The differences of serum MIP-1α,inflammatory factors,imnmunoglobulin and lung function were observed in two groups.The correlation between MIP-1α and inflammatory factors,lung function and immunoglobulin were analyzed.Results The levels of MIP-1α,interleukin (IL)-6,and tumor necrosis factor-α (TNF-α) in patients with asthma were significantly higher than those in control group (t =-207.04,-33.209,-55.132,P ＜ 0.01);The levels of forced vital capacity (FVC),the forced expiratory volume in one second (FEV1),FEV1/FVC,maximal mid expiratory flow (MMEF),and peak expiratory flow (PEF) in the asthma group were significantly lower than those in the control group (t =17.100,39.154,22.791,25.391,19.356,P ＜ 0.01).The IgG and IgM of asthma group were significantly lower than those of the control group (t =9.564,7.528,P ＜ 0.01).The IgE level was significantly higher than that of the control group (t =-82.683,P ＜0.01).The level of MIP-1α was positively correlated with the levels of IL-6,TNF-0 and IgE,and negatively correlated with FVC,FEV1,FEV1/FVC,MMEF,PEF,IgG and IgM in patients with asthma.Conclusions The level of serum MIP-1 α in asthmatic patients is high,and is closely related to the inflammatory cytokines and lung function in patients with asthma.

Objective To investigate the patients with postoperative skin damage around the stoma after Miles operation,take measures according to the influencing factors,and explore an effective way to reduce the incidence of skin damage around the stoma patients.Methods There were 62 cases of skin damage around the stoma in 110 cases of patients with permanent colostomy in out-patient follow-up.Each patient with skin damage occurring around the stoma were retrospectively analyzed the reasons,and the related factors that might affect Miles postoperative stoma skin damage were analyzed.Results The incidence rate of Miles postoperative skin damage around the stoma was 56.36％,through the multi-factor Logistic regression analysis,there were six related factors with the Miles postoperative skin damage around the stoma,patients' excrement stimulation,ostomy bag allergies,improper operation of the replacement of the ostomy bag,the potential skin disease,excessive scrub / rub the skin,unfamiliar with ostomy care knowledge were the influencing factors of patients with skin damage around the stoma.Conclusions Appropriate stoma care products and paste methods,detailed guiding of patients and their families about ostomy care knowledge and skills can significantly reduce the incidence rate of Miles postoperative skin damage around the stoma.

Objective To investigate the efficacy and safety of Solifenacin for the treatment of overactive bladder in children. Methods A retrospective analysis was done in a children admitted to our hospital in January 2010,with lower urinary tract obstruction lead to overactive bladder.The boy was 4 years old,suffering from difficult urinating,urinary frequent,urgency and incontinence for 4 years.Imaging studies (B ultrasound,intravenous urography,CT,bladder voiding urethrography) found bilateral hydronephrosis and kidney collecting system separation with left 3.3 cm and right 2.3 cm in diameter; ureteral dilation with left 1.3 cm,right 1.6 cm in diameter.A transverse septum crossing the urethra at a right angle distal to the verumontanum was detected.According to history,physical examination and imaging examination,a diagnosis for posterior urethral valves was established.Under general anesthesia,urethroscopy found that the valve was attached below urethra wall,divided into two forks towards urethral lateral wall.The valve was excised.Three months later,although good voiding,the hydronephrosis and hydroureter still did not improve.After cystostomy and 6 months follow-up,hydronephrosis and hydroureter still not improved. B ultrasound showed the renal pelvis dilation with left 3.2 cm,right 2.0 cm in diameter,and bilateral ureteral dilation with left 1.3 cm,right 1.4 cm in diameter.Solifenacin (5 mg/tablet),1/3 tablet,about 1.7 mg per day was added. Results After oral Solifenacin one month,hydronephrosis and hydroureter began to improve.After 3 months,hydroureter disappeared; hydronephrosis improved significantly.. B-ultrasound showed the renal collecting system mild dilation with left 1.1 cm,right 1.0 cm in diameter.After 13 months follow-up,no side effects was detected. Conclusions Combined with the surgical treatment,Solifenacin can alleviate hydronephrosis secondary to OAB,and can also protect the renal function.

Objective To study the preventive effects of vitamin K2 on tumor recurrence in patients with hepatocellalar carcinoma (HCC) after radical resection. Methods The clinical data of 50 patients with HCC who received radical resection from March 2006 to March 2007 in No. 181 Hospital of PLA were analyzed retrospec-tively. All the patients were divided into 2 groups according to the random number table. Twenty-six patients in vitamin K2 group were administered with menatetrenone (45 mg per day), and the rest 24 pateints were in the control group. The accumulative and tumor-free survival rates, differences between the 2 groups, multivariate factors for prognosis were analyzed by Kaplan-Meier curve, Log-rank test and Cox regression model, respectively. Results During a period of 36 month follow-up, 10 patients died and 28 had tunor recurrence. The 1-, 2-, 3-year accumulative survival rates were 96%, 92% and 83% in vitamin K2 group, and 96%, 82% and 63% in control group (χ2 = 3.61, P > 0.05). The 1-, 2-, 3-year tumor-free survival rates were 92%, 60% and 38% in vitamin K2 group, and 75%, 42% and 12% in control group, with significant difference between the 2 groups (χ2 =5.61, P <0.05). Univariate and multivariate Cox proportional hazard analysis showed that without taking menate-trenone, the preoperative level of alpha fetoprotein (AFP) ≥800 μg/L and vascular invasion were the indepen-dent risk factors for tumor recurrence. Conclusions Vitamin K2 has a suppressive effect on tumor recurrence of HCC, while patients with AFP≥800 μg/L before operation or with vascular invasion have poor prognosis.

Objective To investigate the prevalence rate of thyroid nodules as well as related influencing factors. Methods In this clinical study, 8,912 healthy people were included, involving medical staff, teachers, electric enterprise staff and civil authorities from January to December in 2014 . The prevalence rate of thyroid nodules and related influencing factors were investigated . Results (1) The prevalence rate of thyroid nodules was 40.4%, 34.9%for male and 46.7%for female. The prevalence of female was higher than that of male (P<0.001);(2) The prevalence rate of thyroid nodules showed a trend of increase with age (P<0.01);(3) The prevalence rate of thyroid nodules in medical staff and teachers was significantly higher than others (P<0.001);(4) The difference was statistically significant in BMI, blood pressure, blood lipid, blood glucose in thyroid nodule group and non thyroid nodules group (P<0.001). All indexes mentioned above of thyroid nodule group was much higher than those of non thyroid nodules group. (5) The prevalence rate of breast hyperplasia of females under the age of fifty years was significantly higher than those of non thyroid nodule group (P<0.001). Conclusion The prevalence rate of thyroid nodules is high. It is related to gender, age, occupation and estrogen. Effective measures should be taken to change people's bad habits, blood sugar control and blood pressure, reduce BMI and work tension in order to reduce the incidence of thyroid nodules.
