ABSTRACT
Objective@#To analyze the trends and influencing factors of endurance performance of 19-22 years old college students in Hunan Province from 1985 to 2019, so as to provide objective and scientific basis for sports and health work in colleges and universities.@*Methods@#A retrospective analysis was conducted on the data of 14 490 college students aged 19-22 in Hunan Province from 8 consecutive National Student Physical Fitness and Health Surveys conducted from 1985 to 2019. The analysis indexes were 1 000 m running for boys and 800 m running for girls.@*Results@#From 1985 to 2019, the endurance running time of 19-22 years old Han college students in Hunan Province showed an obvious trend of decline. The 1 000 m running time of urban and rural male students increased by 41.9 and 45.4 s on average, and the 800 m running time of urban and rural female students increased by 29.5 and 30.6 s on average, respectively. Multiple linear regression analysis showed that age ( β =0.17), urban students (rural students as reference; β =0.44), GDP ( β =0.94) and urbanization level ( β = 0.44 ) were positively correlated with the average endurance running time of males. Urban students ( β =0.92), GDP ( β = 1.38 ) and Engel coefficient ( β =0.93) were positively correlated with the average endurance running time of females. BMI ( β =-0.47) was negatively correlated with the females mean time of endurance running ( P ＜0.05).@*Conclusion@#The endurance performance of Han college students in Hunan Province showed a declining trend from 1985 to 2019,which is associated with age, urban and rural distribution, regional GDP, Engel s coefficient, urbanization level and BMI. Effective measures should be taken to improve the physical quality of college students.
ABSTRACT
Objective To investigate the efficacy of entecavir after partial embolization in patients with hepatitis B cirrhosis complicated with hypersplenism.Methods From February 2016 to October 2016,the clinical data of 92 patients with hepatitis B cirrhosis and hypersplenism in the First People 's Hospital of Taizhou were retrospectively analyzed.Among them,46 cases were treated with lamivudine antiviral therapy after partial embolization as the control group.46 cases were treated with entecavir tablets after partial embolization as the observation group.After 36 weeks of contact therapy,liver fibrosis was compared between the two groups:procollagen Ⅲ (PC-Ⅲ),serum hyaluronic acid (HA),collagen Ⅳ (Ⅳ-C).The liver function of the two groups were compared:total bilirubin (TBil),alanine transaminase (ALT),albumin (ALB),aspartate aminotransferase (AST).The the control of hepatitis B virus were compared between the two groups:HBeAg/anti-HBe negative,negative HBV DNA.Results Liver fibrosis:the levels of PC-Ⅲ,HA and Ⅳ-C in the observation group were (93.6 ± 31.3) U/L,(83.2 ± 25.4) U/L and (85.5 ± 25.4) μ mol/L,respectively,which were significantly lower than those in the control group [(148.6 ± 24.4) U/L,(152.2 ± 34.5) U/L and (146.1 ± 36.6) μmol/L],the differences were statistically significant (t =3.457,3.848,4.065,all P ＜ 0.05).Liver function:the levels of TBil,AST and ALT in the observation group were (21.4 ± 5.4) μmol/L,(60.1 ± 20.6) U/L,(52.4 ± 15.4) U/L,respectively,which were significantly lower than those in the control group [(51.1 ± 6.7) μmol/L、(116.4 ± 25.5) U/L、(110.9 ± 20.5) U/L],the differences were statistically significant(t =4.106,3.763,2.945,all P ＜ 0.05).The ALB in the observation group was significandy higher than that in the control group [(31.2 ± 1.5) g/L vs.(35.9 ± 2.8) g/L,t =2.966,P ＜0.05].Hepatitis B virus control:the observation group and control group had 13 cases and 2 cases in HBeAg/antiHBe negative,respectively,the difference was statistically significant (x2 =5.035,P ＜ 0.05);the observation group and control group were 15 cases,2 cases in HBV DNA negative,respectively,the difference was statistically significant (x2 =5.364,P ＜ 0.05).Conclusion The treatment of entecavir by partial embolization of patients with hepatitis B cirrhosis complicated with hypersplenism can well control the liver function and hepatitis B virus replication and reverse the control of liver fibrosis.Antiviral therapy after embolization has an important role.
ABSTRACT
Objective Through To analyzing analyze the pathogen distribution and resistance analysis of elderly patients with pulmonary infection,in order to provide basis for clinical rational administration.Methods The clinical data of 285 elderly patients diagnosed as pulmonary infection were selected,and their sputum specimens cultivation were collected for statistical analysis,and the pathogenic bacteria distribution and drug resistance were analyzed.Results 292 strains of pathogenic bacteria were detected from 285 patients,of which 204 strains of gramnegative bacteria,accounting for 69.8％,mainly including pseudomonas aeruginosa,acinetobacter baumannii and klebsiella pneumoniae,while 84 strains of gram-positive bacteria,accounting for 28.8％,mainly including staphylococcus aureus and 4 strains of fungus,accounting for 1.4％.Different pathogens showed different degrees of antimicrobial resistance:pseudomonas aeruginosa,acinetobacter baumannii,klebsiella pneumoniae and e.coli had highly sensitivity for imipenem and meropenem,which were secondly sensitive to amikacin and highly resistant to ampicillin;Staphylococcus aureus and epidermis staphylococcus were all sensitive to linezolid and vancomycin,which were highly resistant to benzyl penicillin.Conclusion Gram-negative bacilli is the main bacteria for patients with pulmonary infection,which has higher antimicrobial drug resistant rate,and antimicrobial agents should be rationally used according to drug susceptibility results.
ABSTRACT
Objective To study the clinical effects and side effects of recombinant human vascular endostatin combined with pemetrexed and cisplatin in the treatment of advanced lung adenocarcinoma.Methods Forty-seven patients with advanced lung adenocarcinoma were recruited from Jan 2011 to Jan 2013,and they were randomly divided into experimental group and control group.The experimental group (n =24) was added with recombinant human vascular endostatin based on pemetrexed and cisplatin,whereas the control group(n =23) was administered with pemetrexed and cisplatin only.The objective response rate (ORR),disease control rate (DCR),progressive disease (PD) rate,progression-free survival (PFS),overall survival (OS) and the side effects of 2 groups were evaluated.Results In the experimental group,ORR,DCR,PD rate,PFS and OS were 41.7 ％ (10/24),79.2 ％ (19/24),20.8 ％ (5/24),8.0 months and 12.5 months respectively,while those of control group were 34.7 ％ (8/23),47.8 ％ (11/23),52.2 ％ (12/23),6.2 months and 10.0 months.DCR,PD rate and PFS of experimental group had significant differences compared with control group (P ＜ 0.05).OS of experimental group had no significant difference compared with control group (P ＞ 0.05).The side effects of 2 groups were mainly hematologic toxicities,digestive reactions and fatigue,and the incidence rates were not significantly different between 2 groups (P ＞ 0.05).Conclusions Recombinant human vascular endostatin combined with pemetrexed and cisplatin in treatment of patients with advanced lung adenocarcinoma improves the DCR,decreases the PD rate,prolongs the PFS.There is an increasing trend in the OS of experimental group,and with tolerable side effects.
ABSTRACT
Objective: To study the expression and significance of VEGF-C, D2-40, and E-Cad in Human breast carcinoma. Methods: S-P immunohistochemical method was used to assess the expression of VEGF-C in 88 cases of infiltrating ductal carcinoma of the breast (with intact clinicopathologic and follow-up in-formation) and 54 cases of different intraductal hyperplastic lesions. The relationship of VEGF-C expression with D2-40 and E-Cadherin in infiltrating ductal carcinoma of the breast was analyzed. Results: VEGF-C ex-pression was higher in the invasive group than that in the dysplasia group and benign lesions. VEGF-C ex-pression in the metastatic group was significantly higher than that in the group without lymph node metasta-sis, indicating that VEGF-C plays an important role in the growth and metastasis of breast cancer. VEGF ex-pression in breast cancer group was higher than that in the dysplasia group and benign lesions. LVD count in the group with lymph node metastasis was significantly higher than that in the group without lymph node me-tastasis. The positive rate of E-Cad expression in the invasive group was significantly lower than that in the dysplasia group and benign lesions. VEGF-C expression was positively correlated with D2-40 expression. VEGF-C expression was negatively correlated with E-Cad expression. Conclusion: VEGF-C and D2-40 could be used for the detection of early lymphatic metastasis of breast cancer. VEGF-C and E-Cad can be used as important indices for the evaluation of the prognosis of breast cancer.
