Clinical efficacy scale of traditional Chinese medicine (TCM) should be built according to the characteristics of TCM, scientific demand, and demonstrated by practice. This paper provides some considerations of the scale.

Objective To evaluate the association between the expression of PTEN protein and the clinicopathological char‐acteristics of breast cancer patients .Methods All eligible studies regarding the association of PTEN protein expression with clini‐copathological features in patients with breast cancer were retrieved from PubMed ,Embase ,Cochrane Library ,CNKI and Wanfang databases .Odds ratio(OR) with corresponding 95% confidence interval(95% CI) form eligible studies were pooled .Heterogeneity and publication bias were also evaluated .All analyses were operated using RevMan 5 .2 software .Results A total of 28 articles con‐taining 3 172 patients were ultimately included for this Meta‐analysis .Our findings revealed that the expression level of PTEN was significantly correlated with estrogen receptor status(OR= 3 .16 ,95% CI:2 .01 -4 .97 ,P< 0 .01) ,progesterone receptor status (OR=2 .27 ,95% CI:1 .70 -3 .04 ,P<0 .01) ,lymph node metastasis(OR=0 .36 ,95% CI :0 .27 -0 .49 ,P<0 .01) ,clinical stage (OR=2 .59 ,95% CI:2 .04-3 .30 ,P<0 .01) and histological grade(OR=2 .19 ,95% CI:1 .74-2 .75 ,P<0 .01) .Conclusion Aber‐rant PTEN expression might have strong impacts on carcinogenesis ,tumor progression ,invasion and prognosis ,which makes it a potential biomarker for early cancer screening and endocrine therapy in breast cancer .

OBJECTIVE:To observe the clinical efficacy,safety,the maximal tolerated dose(MTD) and dose-limiting toxicity(DLT) of docetaxel(TXT) in the treatment advanced breast cancer.METHODS:Docetaxel was given by drip infusion in escalating doses from the initial dose of 65 mg?m-2 to 75 mg?m-2 and 85 mg?m-2 until the appearance of DLT.RESULTS:Among the 15 cases,1 case with CR,5 PR,4 SD,and 5 PD.The DLT of TXT was neutropenia,and its MTD was 85 mg?m-2.CONCLUSION:Docetaxel(at a dose of 75 mg?m-2) showed remarkable efficacy and good tolerance in patietns with advanced breast cancer.

Brain injury of premature infant is a hot topic in the neonatal clinical study. Early diagnosis and intervention can improve the prognosis of premature infants. Although there are some interventions for brain injury of premature infants, most of them do not have evidence-based study to support the clinical application. Antenatal application of magnesium sulfate for pregnant women and application of erythropoietin for preterm infants may be the most promising interventions. Avoiding prematurity and brain damage is the key interventions for brain damage of premature infants.

Based on the shortcomings of graduate education in clinical medicine of our country and the characteristics of this specialty, the author point out that the cultivation of graduates in otolaryngology, head and neck surgery should be focused on the training of humanities, professional knowledge and skills. And they also make some suggestions and discussion about the reform of graduate education mode.

Falling in the elderly is a major health problem and may cause severe consequences. Fall risk assessment is important for preventing and intervening fall incidence. Inertial Measurement Unit (IMU) has been introduced to evaluate motion/balance function and fall risk among the older people. Some researches indicated that it might have advantages over the usual tools, and can be used in the hospitals, communities, nursing homes, etc. IMU is a good way to measure gait variability, which may be strongly related with the risk of falls.

Objective To investigate the dynamic changes of metallothionein(MTs)gene expression and explore the important significance of MTs during hepatocarcinogenesis.Methods One hundred and twenty-five SPF 5 -8-week old male C57BL/6J mice were randomly divided into control group and model group.Diethylnitrosamine (DEN) was given to the mice at a dose of 100 mg/kg, ip, and 50 mg/kg, ip, in the first and next week, respectively.The mice were given ethanol (53%, 5 mL/kg/day, 5 days/week) from the third week of experiment till 35 weeks.At 1, 3, 9, 13, 24 and 35 weeks of the experiment, liver samples were taken for histopathological examination of liver damages and incidence of HCC. The liver index and malondialdehyde (MDA) of liver homogenate were determined.All liver tissue samples were examined by histopathology using hematoxylin and eosin (HE), Masson and reticular fiber staining.Real-time RT-PCR was used to analyze the mRNA expression level of liver metallothionein-1 /2 (MT-1 /2) in different periods.Results Progressive liver damages in model group mice were identified in different periods.Hepatocytes abnormal tission and abnormal liver plate structure, architecture often characteristic of HCC could be seen in approximately 50% of mice at 35 weeks.In addition to these, a higher liver index also were seen at 35 weeks.Increased MDA levels in the mouse liver tissues were observed in each stage.Real-time RT-PCR analysis showed that significantly increased transcription of MT-1 and MT-2 at 1, 3 and 9 weeks, then gradually declined and even below the normal level.Conclusions MTs gene expression levels in mouse liver tissues are changed from significantly increased in the early stage of injury to decreased expression combined with distinct fibrosis. Our findings further demonstrate that the down-regulation of MTs level is closely correlated with hepatocarcinogenesis.

Objective This paper aims to assess the clinical efficacy of pemetrexed maintenance therapy in patients with advanced non-small cell lung cancer( NSCLC) through Meta analysis.Me thods Systematic lit-erature searches were performed in Cochrane、Pubmed,Web of science, Embase and ClinicalTrials databases.The related references had been traced.We made quality assessment of qualified randomized controlled trials( RCTs) of pemetrexed maintenance therapy compared with best supportive care( BSC) in advanced NSCLC.Besides,we u-tilized stata 12.0,Revman 5.3 and GRADEpro software to evaluate the overall quality of the evidence,according to the Cochrane collaboration to perform Meta-analysis.Resutl s Three RCTs were eligible and included 1257 patients.Meta-analysis results suggested that:compared to BSC,pemetrexed maintenance therapy had a statisti-cally significant benefit in improving progression-free survival(PFS)(HR =0.55,95% CI:0.48~0.64)and overall survival(HR=0.76,95%CI:0.65~0.88).The objective response(ORR)did not reach statistical signif-icance(RR=0.97,95%CI:0.86~1.10).Conclusion Compared with BSC,pemetrexed maintenance therapy statistically significantly improve PFS and OS,but has no demonstrable impact on ORR in patients with advanced NSCLC.

Objective To probe the effects of hypothermia and St Thomas Hospital Ⅱ cardioplegia on immature myocardium.Methods To observe the change of hemodynamics,myocardial enzyme in the coronary effluent and myocardial biochemistry of the perfused immature rabbit heart in vitro after two or four hours ischemia at 14 degrees centigrade.Results There were no significant differences in post ischemic hemodynamics,myocardial enzyme in the coronary effluent and myocardial biochemical parameters of the perfused immature heart The myocardial protective effect provided by St.Thomas Hospital Ⅱ cardioplegia was worsen than that of hypothermia alone,marked by the elevated myocardial enzyme leakage and the decreased hemodynamics.Single dose perfusion was better than multi dose perfusion by characteristics of decreased enzyme leakege and good post ischemic hemodynamics.Conclusions Hypothermia alone can provide immature heart with satisfactory myocardial protection.St.Thomas Hospital Ⅱ cardioplegia can not afford good myocardial protection to immature heart and enhance the myocardial protective effect provided by hypothermia.The myocardial protection effect is better provided by single dose perfusion than by multi dose perfusion
