Objective To analyze the epidemiological trend and distribution of stroke mortality in residents of Tianjin, China. Methods The study was based on 102 718 died cases with stroke in Tianjin between 1999 and 2006. The death cause and the stroke typing were coded according to the ICD -9 and ICD -10. Standardized mortality rates were calculated for stroke and its subtypes, adjusted for age and sex according to the world standard population of the Year 2000. The age, sex and geographic distribution of the stroke and its subtype mortality were analyzed. Chi-square tests were used to determine the statistical significance of mortality trends and differences. Results Stroke mortality rate in Tianjin declined from 133.52 / 100 000 / year in 1999 to 102.52 / 100 000/year in 2006. Cerebral infarction accounted for more than 50% of stroke mortality. The stroke mortality rate for males (120.17 / 100 000 to 157.74 /100 000) was higher than that for females (84.87/100 000 to 109.31/100 000). Stroke mortality rates elevated with age (P

Objective To investigate the effects of vitamin K1 in the adjuvant treatment of spasmodic cough in pertussis syndrome children,and its impacts on length of hospital stay.Methods 87 pertussis syndrome children were randomly divided into two groups,among which 41 cases in the control group were treated with the therapies such as anti -infection,respiratory support,antispasmodic,expectorant et al,while 46 cases in the treatment group were treated additionally with vitamin K1 on the basis of the control group.Then compared the duration and hospital stay of the two groups with spasmodic cough.Results The disappeared time of spasmodic cough in the treatment group was (7.22 ±1.33)d and hospital stay was (9.52 ±1.84)d,which in the control group were (15.51 ±2.73)d,(18.71 ± 3.30)d respectively,and there were statistically significant differences(t =-18.310,-16.269,all P <0.01).In the treatment group,the total effective rate was 93.5%,there were 18 cases with markedly effective,25 cases with effective and 3 cases with ineffective.Correspondingly,there were 7 cases markedly effective,23 cases effective, 11 cases ineffective,and total efficiency rate was only 73.1% in the control group,the difference was statistically significant(χ2 =4.285,P <0.05 ).Conclusion Vitamin K1 to alleviate spasmodic cough in children has a significant effect,which can reduce the duration of the cough time and hospital stay in pertussis syndrome children, and also can improve the clinical effect.

Since intra-arterial chemotherapy with the help of implantation of port-catheter system (PCS) was first used in the surgical field in 1981, PCS has been widely employed in the field of interventional radiology. Intra-arterial chemotherapy by implantation of PCS has some certain advantages such as minimal invasion, no need of general anesthesia, etc. Ten randomized clinic trails have been already reported, which indicate that intra- arterial chemotherapy with PCS is obviously superior to systemic chemotherapy in treating hepatic metastasis form colorectal cancer. As for the treatment of advanced biliary tract cancer, pancreatic carcinoma and hepatocellular carcinoma, the relevant reports can be found only in several phaseⅠ/Ⅱclinical trials or in some retrospective cohort studies. This paper aims to make a comprehensive review about the indications, clinical applications and complications of PCS in treating abdominal tumors in order to improve the clinical practice.

Objective To analyze the risk factors of 30-day mortality in patients with malignant hilar obstruction (MHO) after percutaneous transhepatic biliary metal stent deployment. Methods One hundred and fifty-nine consecutive patients with MHO caused by cholangiocarcinoma or gallbladder carcinoma were enrolled in this study. Percutaneous transhepatic biliary stent (PTBS) implantation was carried out in all the patients. Independent predictors for 30-day mortality were evaluated by logistic regression analysis. Covariates that were incorporated into the multivariate analysis were the variables that reached statistical significance (P < 0.1) in univariate analysis. Two-tailed, P value of less than 0.05 was considered to be statistically significant. Results The 30-day mortality of patient with MHO after metal stent deployment was 9.4%. Univariate analysis indicated that the differences in WBC (OR = 1.224.95%CI [1.07 - 1.44], P < 0.01), INR (OR=78.75, 95%CI [5.02-1 235.70], P<0.01), PT(OR=1.55, 95%CI [1.18-2.04], P<0.01), BUN (OR=1.19, 95%CI [1.02- 1.38], P < 0.05), CRE(OR = 1.02, 95%CI [1.000 - 1.041], P < 0.1) and lymph nodes metastasis(OR = 0.334. 95%CI[0.105 - 1.131], P < 0.1) were statistically significantly between 30-day mortality group and non-30-day mortality group. Multivariate analysis showed that statistically significant differences in WBC (OR = 1.19, 95%CI[1.026 - 1.380], P < 0.05), INR(OR = 151.5, 95%CI [3.13 - 5 440.7], P < 0.05) and CRE (OR = 1.025, 95%CI [1.002 - 1.048], P < 0.05) also existed palliative treatment for patients with malignant hilar obstruction. Active preoperative measures to improve hepatic and renal functions as well as to control infection are necessary in order to reduce 30-day mortality.

Objective To investigate the effect of elevating the root of tongue bare-handed to assist ProSeal laryngeal mask airway insertion in patients with tongue body hypertrophy under general anesthesia. Methods Sixty ASAⅠ~Ⅲgrade patients with tongue body hypertrophy undergoing surgery in general anesthesia were randomly divided into two groups:30 cases in each group. After anesthesia induction ,laryngeal mask airway was inserted in the observation group with assistance of elevating the root of tongue bared-handed ,while inserted in the control group by standard method.Insertion time ,success rate of the first and secondary and total insertion ,pharyngolaryneal complications at 24 hours after removal were recorded ,as well as the success rate of gastric tube intubation was recorded. Results Compared with the control group ,insertion time was significantly shortened (P < 0.05). Success rate of the first and total insertion were increased (P < 0.05).Success rate of gastric tube intubation was increased(P < 0.05),and pharyngolaryneal complications were decreased (P < 0.05) in the observation group. Conclusions Elevating the root of tongue bare-handed to assist ProSeal laryngeal mask airway insertion in patients with tongue body hypertrophy is a simple and fast method with high success rate ,good apposition and less complications. Its efficacy is better than that of the standard method.

Objective To analyze the economic effects of different rehabilitation patterns for children suffering from cerebral palsy. Methods A total of 153 cerebral palsy patients were divided into a hospital-community-family rehabilitation group(n = 52), a hospital rehabilitation group (n = 50) and a non-intervention control group (n = 51). Those in the first group were provided with a hospital-community-family rehabilitation therapy pattern, those in the sec-ond only hospital rehabilitation and the third no intervention. All the patients were evaluated using the Gross Motor Function Measure-88 (GMFM-88) Scale and the Cost Measure Scale at admission, and at the end of the 3rd and 6th months of treatment. Results There were no significant differences in gross motor function among the three groups at admission. At the end of the 3rd month and the 6th month there were significant differences between the children in the hospital-community-family rehabilitation program and those in the hospital rehabilitation program in terms of gross motor function. Their general percentage, monthly percentage and monthly relative percentage results were all significantly different. But there was no significant difference in the non-interventian control group since admission. Every unit of improvement in gross motor function cost $101.87±97.59, $75.11±45.75 in the hospital-community-family reha-bilitation program and $387.21±54.76, $170.31±123.16 in the hospital rehabilitation program at the end of the 3rd and the 6th month respectively. So the cost of the former was only about 30% of the latter. Conclusion Hospital rehabilitation is suitable for the early rehabilitation of cerebral palsy children. Hospital-community-family rehabilitation is better for long-term rehabilitation of cerebral palsy children, and what is more, it can decrease the rehabilitation ther-apy cost substantially. So a hospital-community-family rehabilitation pattern is more compatible with China's national situation.
