Public health awareness existed in the practice of traditional Chinese medicine (TCM) long ago. In the process of Shanghai's modernization and in competition with Western medicine, TCM in Shanghai has gradually accepted the modern public health awareness, fostering its strengths, circumventing its weaknesses and playing an important role in the local public health service. To study the vicissitude of TCM public health awareness at this time will be helpful to further understand the modern history of TCM and also provide useful reference for further participation of TCM in modern public health enterprise. In this paper, the authors used literature analysis and historical research to analyze the medical practice and writings of representative TCM practitioners, medical groups and journals. The results showed that the public health awareness of TCM in Shanghai has evolved from its traditional pattern to the modern pattern seen today; the traditional pattern was characterized by individual health care and some degree of medical collaboration, whereas the modern pattern is characterized by public health education. This process was propelled forward throughout by intense national spirit. TCM has made significant contributions to the local public health service in Shanghai in the late Qing Dynasty, which promoted the modernization of public health awareness of TCM in the People's Republic of China. The authors also found that one of the ways of modernizing TCM is to diversify the ways of publicizing TCM and make it easily understood, which can shed a new light on promoting the development of TCM.

Objective To determine the pathogen profile and antibiotic resistance in aerobic isolates from blood cultures of neonates. Methods All blood culture reports (n=28120) from newborns admitted to the Department of Neonatology during 2002-2012 were analyzed, and the sensitivity patterns were recorded. Results A total of 1665 bacteria were isolated from 1606 blood culture-positive samples and the positive rate of blood cultures was 5.7%(1606/28120). Gram-positive bacteria were iso-lated in 1336 cases, with Staphylococcus epidermidis (902 cases) and Staphylococcus haemolyticus (206 cases) being the com-mon bacteria. Klebsiella pneumoniae (108 cases), followed by Escherichia coli (73 cases), were the major Gram-negative bacte-ria (235 cases). The determination of the antibiotic resistance of aerobic isolates was performed in 2012. Most Gram-positive iso-lates were sensitive to vancomycin and moxifloxacin, and more than 90%were resistant to penicillin while most of Gram-nega-tive isolates were sensitive to amikacin and imipenem. Conclusions Staphylococcus epidermidis, Staphylococcus haemolyticus, Klebsiella pneumoniae and Escherichia coli remain to be the principal organisms responsible for neonatal sepsis.

Objective To evaluate the value of ultrasonic diagnosis of congenital prepyloric diaphragm. Methods Twelve cases were collected for the analysis of the characteristics of ultrasonography in diagnosis of congenital prepyloric diaphragm. Results Of the 12 cases of congenital prepyloric diaphragm, valvula in pyloric antrum could be observed in 5 cases, inclusive of 2 cases of complicating pachyntic stenosis of pyloric muscular layer. Other valvula in pyloric canal could not be found with ultrasonography. No pyloric muscular layer pachynsis was observed, but signs of pyloric obstruction such as gastric retention, slow or difficult transfer of gastric contents, gastro-esophageal reflux were found. Prepyloric diaphragm was confirmed surgically in all cases. Conclusion Ultrasonic diagnosis of congenital prepyloric diaphragm is of practical value in clinical practice and can provide reliable imaging data for the option of preoperative approaches.

Objective To evaluate the relationship between the existence of DME and the SFCT in DR pa-tients. Methods We collected 70 cases which were clinical diabetic involving 122 eyes. They are 36 men with 64 eyes and 34 women with 58 eyes. The average age is 56.7 ± 9.7 year-old. All patients had been examined by oph-thalmologic examination. Grouping: patients without diabetic retinopathy (NDR) group; mild-to-moderate NPDR group; severe NPDR group; PDR group. The last three groups were divided into two subgroup groupsrespectively , which were cases with and without significant macular edema (CSME + / CSME). EDI was used to measure the SFCT. SPSS 17.0 software was used for statistical analysis. Results The average SFCT of NDR group, mild-to-moderate NPDR group, severe NPDR group and the PDR group respectively were (282.94 ± 104.21)μm, (313.62 ± 94.40)μm, (382.44 ± 76.91)μm, (335.00 ± 73.82)μm. Compared with the NDR group, SFCT was thicker than the other three groups, and difference was statistically significant (F = 2.786, P = 2.786). There were no statisti-cally significant difference of SFCT between the mild-to-moderate NPDR/CSME - group and mild-to-moderate NPDR/CSME + group, severe NPDR/CSME - group and severe NPDR/CSME + group PDR/CSME-group, PDR/CSME + group. Conclusions The SFCT of DR patients could potentially be thickenedas disease became serious. When considered the same degree DR, there is no obvious difference of SFCT between patients with CSME and without CSME.

AIM: To explore a simple, reliable method for tissue processing and section staining by extracting DNA from the manually microdissectioned specimen, and to identify whether the extracted DNA is useful in the following study at molecule level. METHODS: The experiment was performed at the pathological laboratory of Guangdong Medical College from July 2004 to July 2007. The paraffin imbedding tissue sections of cervical cancer were thoroughly deparaffinized after mounted on slides for a long period of time. The nucleus was slightly stained with hematoxylin and microdissectioned under inverted microscope. The microdissectioned samples were put into EP tubes filled with digestion buffer to split the cells and then the DNA was extracted. During the whole course, PE tubes did not change, and the complicated phenol/chloroform extraction did not perform. The DNA extraction was rapid and simple. RESULTS: The DNA was measured by the spectrophotometer with concentrations from 0.14 to 5.25 g/L and absorbance values of A260/A280 were 1.6-1.8. All samples were amplified with PCR to produce expected length specific target fragment (231 bp). CONCLUSION: Rapid DNA extraction after manual tissue microdissection can produce adequate amount of DNA and maintain good quality of DNA template for PCR. The DNA meets the need of the following molecular experiments.

Objective To investigate the differences between animal temperature controller (ATC) and artificial climate chamber (ACC) used for the establishment of classical heat stroke (CHS) rat model.Methods Twenty-four male specific pathogen-free Wistar rats were randomly (random number) and equally assigned to three groups,namely room temperature control (C-C) group,heat stroke under conscious state (HS-C) group,and heat stroke under anesthesia (HS-A) group.Rats of HS-C or HS-A group were placed into ACC or ATC,then exposed to 35 ℃ heat stress.The systolic blood pressure (SBP) and core body temperature (Tc) were monitored.The time required for onset of HS was recorded.The white blood cell count (WBC) in peripheral blood and serum levels of C-reactive protein (CRP),tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) were measured.The histopathological changes of major organs were also confirmed by hematoxylin-eosin (HE) staining.Results The onset time in HS-A group was significantly shorter thanthatin HS-C group [(40.0 ± 4.3) minvs.(110.1 ± 5.3) min,P＜0.01].The SBP and Tc at this moment were lower in HS-A group [(159.1 ± 5.91) mmHg vs.(174.54 ± 5.77) mmHg,P＜0.01;(43.5 ± 0.4)℃ vs.(44.4 ± 0.2)℃,P＜0.01].TheWBC,CRP,TNF-α and IL-1 β levels of these two HS groups were dramatically elevated compared with C-C group (P ＜0.01).The inflammatory cytokines levels in HS-A group were significantly lower than those in HS-C group (P ＜ 0.01),but there was no difference in WBC between them (P ＞ 0.05).However,there was no obvious difference in histopathological change in major organ observed between HS-A and HS-C groups.Conclusions In comparison of these two methods,ATC is similar to ACC in respect of the establishment of CHS rat model.ATC is quicker in onset of HS,and more simplified and economical than ACC and could substitute ACC.

ObjectiveTo evaluate the efficacy and safety of the angiotensin Ⅱ receptor blockers (ARB) in reducing portal hypertension ( PHT) in patients with cirrhosis.Methods PubMed,EMBASE,Web of Science,The Cochrane Central Register of Controlled Trials,Chinese BiomedicalDatabase,ChineseJournals Full-text Database and WanFang Digital Journal Full-text database were searched.Statistical analysis was performed by meta-analysis using RevMan4.2 software.ResultsAmong 8 randomized controlled trials ( RCT) including 282 patients met the inclusion criteria,4 trials were analyzed to compare the ARB with the placebo or no treatment and the other 4 trials were analyzed to compare the ARB with propranolol.Meta-analysis results were as follows.(1) The ARB resulted in more significant hepatic venous pressure gradient ( HVPG) reduction as compared with the placebo or no treatment [ WMD =1.87 mm Hg (1 mm Hg =0.133 kPa),95％CI ( 0.86-2.87 )mmHg,P =0.00003 ].Andthe ARB were similar to propranolol in reducing HVPG [ WMD =0.92 mm Hg,95％ CI ( - 0.41-2.26)mm Hg,P =0.17 ].(2)The ARB led to more significant reduction in mean arterial pressure than the placebo or no treatment [ WMD =8.89 mm Hg,95％ CI( 7.16-10.62)mm Hg,P ＜ 0.00001 ],but they were similar to propranolol had no significant difference.And the ARB had no significant effect on the heart rate of the patients,which was similar to no treatment group ( P ＞ 0.05 ).Whereas,propranolol could greatly decrease heart rate of the patients ( WMD =- 21.25,95％ CI - 25.83-16.68,P ＜ 0.000 01 ).( 3 ) No significant differences were found in serum bilirubin and creatinine levels between the ARB and the placebo or no treatment groups ( P ＞0.05).The rate of nonspecific adverse events was higher in the ARB groups than in the placebo or no treatment groups ( P =0.03 ),but it showed there was no difference between the ARB and propranolol groups (P =0.72).ConclusionThe ARB is effective in reducing portal hypertension in patients with cirrhosis,which is similar to propranolol.Their effects on mean arterial pressure is similar to propranolol without significant effects on hear rate,liver functionand kidney function,and with less nonspecific adverse events.The ARB could become a new choice for the treatment of portal hypertension.

Objective To assess the effect and safety of lanthanum carbonate vs conventional phosphate binders for hyperphosphatemia in patients undergoing maintenance hemodialysis.Methods According to the collaborative search strategy,MEDLINE (1996 to 2012.12),EBCO (1996 to 2012.12),the clinical control test database of Cochrane Library and Chinese Wanfang database (1996to 2012.12) were searched.Related literature,whether Published or not and meeting summary included,were searched by hand.Quality assessment and data extraction were conducted by two independent investigators.Meta-analysis was conducted by RevMan 5.0.The following outcomes were assessed:serum phosphorus levels,serum iPTH levels,serum calcium levels and adverse events.Results were expressed as OR with 95％ confidence interval for dichotomous outcomes and WMD with 95％ confidence interval for continuous outcomes.Results A total of 10 reports were identified which met the inclusion criteria.The meta-analysis showed that the efficacy of treating hyperparathyroidism in hemodialysis patients was similar between lanthanum carbonate and conventional phosphate binders (WMD =-0.06,95％ CI-0.27 to 0.15,P =0.57) and the incidences of discontinuing due to adverse events were also similar.However,there were fewer hypercalcemic episodes and lower serum calcium levels in the lanthanum carbonate group compared to calcium-based phosphorus binders group.Conclusion Lanthanum carbonate is effective and well tolerated in treating hyperphosphatemia in hemodialysis patients with fewer hypercalcemia and lower serum calcium levels compared to calciumbased phosphate binders.

Objective To select a best mouse strain for establishing an animal model of orthotopic transplanted liver cancer through comparison analysis.Methods C57,C3H and BALB/c mice( each 10) were selected as model groupⅠ,Ⅱ and Ⅲ.H22 cells were inoculated into the liver parenchyma of mice in model group along the ventral midline laparotomy.Fifteenth days after injection of laparotomy,the rate of tumor was observed,the volume of ascites and gross tumor volume were measured,and tumor pathology was analyzed.Results The survival rate of mice in three groups was 100%. After 15 days,ascites in three groups were produced,but with no significant difference among the three groups of the volume of ascites.Tumor transplantation rate in model groupⅠwas 100%,which was higher than 60%in model groupⅡand 30%in model group Ⅲ.Liver tumors in model group Ⅰ were all large compact grayish white lesions, and the average tumor volume was significantly greater than that of model group Ⅱ and Ⅲ( P <0.05 ) .Pathology results confirmed that white lesions in liver of three groups were hepatocelluar carcinoma in situ.Conclusion C57 is the better ideal experimental animal for establishing orthotopic liver caner model,and these results will provide a good experimental platform for research in pathogenesis of hepatocellular carcinoma.
