To introduce Prof. T ian Cong-huo’s commonly used acupuncture methods and their clinical application, in order to summarize the famous doctor’s experience, promote the experience inheritance of Chinese acupuncture, and enhance the therapeutic effect of acupuncture.

Objective To study the distribution of pathogenic bacterium and its sensitivity to antibiotic in severe cerebral vascular disease patients with nosocomial pneumonia.Methods Retrospective studies were done in 42 cases of severe cerebral vascular disease patients in neurological intensive care unit (NICU). Secretion from lower respiratory tract was cultivated and done medicine sensitive test at 3 d、4 d、5 d、9 d、16 d after hospitalized,then the etiologic data of nosocomial pneumonia were analyzed.Results Among 42 cases,15 pathogenic microorganisms and 163 strains were cultivated, the fisrt 4 strains were Staphylococcus aureus,Pseudomonas aeruginosa,Klebsiella and Enterobacter cloacae. The results of medicine sensitive test indicated that Gram-negative bacteria was sensitive to Imipenem,and Gram-positive bacteria was sensitive to Vancomycin.Conclusions The main pathogen of nosocomial pneumonia in severe cerebral vascular disease patients may be Staphylococcus aureus,Pseudomonas aeruginosa. Staphylococcus aureus was sensitive to Vancomycin,so Vancomycin can be act as the first choice drug to deal Gram-positive bacteria. Pseudomonas aeruginosa is relatively sensitive to Amikacin and Ciprofloxacin,while Imipenem is the second, but drug fast is to cephalosporins. So the first two antibiotics can be as the experience drugs to deal Pseudomonas aeruginosa.

Objective To investigate the effect of 12-lipoxygenase(12-LOX) inhibitor inducing the apoptosis of human hepatocellular carcinoma cell line HepG2 on the expression of survivin gene.Methods HepG2 cells were cultivated in RPMI-1640 medium.12-LOX mRNA was analyzed by reverse transcription polymerase chain reaction(RT-PCR).The effect of baicalein on the proliferation of the cells was detected by thiazolyl blue tetrazoliumbromide(MTT) method.The subcellular structures were observed under electron microscope.DNA ladder pattern on agarose gel electrophores was used to evaluate the apoptotic index of hepG2 cells.The expression of survivin mRNA was analyzed by RT-PCR.Results 12-LOX mRNA was expressed in human HepG2 cells.At concentrations from 20 to 80 ?mol?L-1,baicalein inhibited the proliferation of HepG2 cells in a concentration-and time-dependent manner from 24 to 72 h.There were significant differences between any other groups(P

Objective To investigate the projects funded by ministry of national science and technology (NSTP) in China allocated to oral medicine from 2003 to 2013.Methods The data regarding the NSTP allocated to oral medicine research from 2003 to 2013 were collected,including funding years,the expenses and numbers of programs,the secondary discipline of oral medicine and the program units,etc.Multidimensional analyses were provided subsequently.Results From 2003 to 2013,a total number of 59 projects and 210 million CNY supported by NSTP were allocated to oral medicineresearch.The development trend showed increased year by year.The oral medicine researches were allocated by almost all major types of NSTP and the funding directions were tending to diversified development.But,the projects units were relatively concentrated in clinical,teaching and research institutions,only few enterprises.Conclusions Over the past 10 years,the sustainable improvement of NSTP in oral medicine research has led to the development of oral medicine discipline.NSTP has becoming an important way for oral medicine research to obtain State-level funding.

winter. The dominant species of algae were Microcystis aeruginosa, Anabaena spiroides and Spirulina . The annual average contents of total nitrogen, total phosphorus and chlorophyl-a were 4. 30 mg/ L, 0.09 mg/ L and 0.015 mg/ L respectively, all of which exceeded the related temporary standards in China. Conclusion The source water of Chaohu Lake had been in the state of serious eutrophication.

Objective To explore the toxicity of algae in water of Chaohu Lake and its influence on the quality of drinking water.Methods In1999,the water samples were collected from the sampling location of A point as a discarded water source for Chaohu Water Plant 1.5km far from the lakeside of Chaohu Lake and the sampling location of B point as a water source in use for Chaohu Water Plant 3.0km far from the lakeside of Chaohu Lake.The species and count of algae in these water samples were analyzed.The determination of micro cystin,sanitary indexes of water quality,Ames test,micronucleus test and SCGE test were carried out in the water samples from B point and the finished water from water plants using water source for B point.Re -sults83species of algae belong to8phylum and49genus were found in water samples from A point and B point in Chao hu Lake.The anual averages of algae count in water sample of B point (8205.67?10 4 /L)exceeded16.8%of that of A point water samples(7024.27?10 4 /L).Microcystin was found in12water samples among total16water samples collected from the lake water,two of which revealed excessive content s of microcystin exceeding standard,but it was not found in raw water and finished water samples from five plants in Hefei and Chaohu Lake[except the4th water plant (4th WP )].After transportation and stor-age,the raw water of4th WP of Hefei with lower content s of microcystin revealed higher contents of microcystin exceeding the standard in primary finished water samples of clean-well finished water storage,but it couldnt be found in secondary finished water samples with the processes of coagulation,ch lorination and active carbon-filtration.The total nitrogen and other6indexes of raw water of4th WP exceeded the related standards ruled by GB3838-2002Surface Water Environment Standard Grade V in different degree,but above6water quality indexes could reach the related sanitary standard after water treatment.Ames test and micronucleus test indicated that the raw water of4th WP presented suspectable mutagenicities which couldnt be removed by co-agulation and chlorination.SCEG test also showed that the organic extracts of the raw water of4th WP presented DNA damage effects.Con clusion The water source in use in Chaohu Lake revealed heavier pollution by algae compared with the original discarded water source in Chaohu Lake.Chaohu Lake water and its finished water revealed higher levels of microcystin exceed-ing the standard and the organic extracts from raw water and finished water presented suspectable mutagenicity.

Objective To transform the equipment with traditional RS232 interface into that with CAN connection interface.Methods On the CAN main line,node is the station for information receiving and transmission in the network.The intelligent node can establish the work way ID,the address and the baud rate through the programming.It is mainly composed by the singlechip and the programmable CAN correspondence controller.Results The hardware and software were designed.SJA1000 initialization,transmission and receiving subroutines are including in the software design.Conclusion CAN is a kind of excellent field bus with high reliability,low cost and has been applied in many fields.It has already formed the international standard and been viewed as one of the most widely used field buses in future.Lots of traditional equipment with RS232 interface are facing the problem of CAN interface transformation.

Objective To analyze the clinical characterist ic s and treatment of chronic idiopathic intestinal pseudo-obstruction(CIIP). Methods We retrospectively reviewed 8 C IIP patients admitted to our hospital from 1980 to 1999. There were 4 males and 4 females, with an average age of 29 years. Results The earliest onset of symptom was at an age of 2 years old. Re current abdominal distention is the most common symptom. Gastrointestinal imagin g and colonoscopy showed dilated loops of bowels with no evidence of mechanical obstruction. Delayed gastric emptying was presented by radionucleotide(~99m Tc-Sc) gastric emptying test. Gastrointestinal manometry showed low pressure in esophagus and colon. Biopsy taken in 2 patients showed chronic inflammation. On e patient underwent total colectomy for the treatment of lesions confined within the colon. Prokinetic agents have limited efficacy. Conclusions CIIP is a rare disease. Operation is not a prima ry method for treatment. The patients usually have poor prognosis.
