OBJECTIVETo observe the immediate antihypertensive effect of guasha combined with bleeding therapy for mild (grade I) hypertension.

METHODSThirty patients with mild (grade I) hypertension and 30 cases with normal blood pressure were compared. Areas and acupoints in governor vessel, meridian of foot-taiyang, meridian of hand-yangming and meridian of foot-yangming were scraped for 3 times, which was followed by bleeding therapy. The blood pressures after each guasha and bleeding therapy were recorded as well as the skin temperature in Dazhui (GV 14) after each guasha. The treatment was given once a week and totally 4 treatments were given.

RESULTSThere were significant antihypertensive effects after the first guasha, the second guasha and the third guasha and bleeding therapy (all P<0.01), in which guasha combined with bleeding therapy had the most significant antihypertensive effect (P<0.01). The skin temperature in Dazhui (GV 14) was obviously increased after three times of guasha (all P<0.01).

CONCLUSIONGuasha or combined with bleeding therapy has better antihypertensive effect for mild hypertension, which is likely to be related with warming stimulation on meridians and acupoints.

Objective To explore the significance of sample cultivation and drug resistance of the patients in PICU with severe lower respiratory tract specimens.Methods 1 107 pathogenic bacteria of lower respiratory tract samples collected were analyzed and the drug resistance was kept watch on.Results A total of 1107 samples were cultured into 948 strains of pathogens,with the positive rate of 85.64%,and 616 strains of Gram negative bacteria accounting for 64.98%,of which 145 strains of Pseudomonas aeruginosa(15.30%),Klebsiella pneumoniae 135(14.24%),Acinetobacter spp 131(13.82%),large intestine Egypt Greek bacteria 89(9.4%);Gram positive cocci 129(13.61%),the main pathogen was staphylococcus aureus and Fungi 203(21.41%),the main pathogen was candida albicans.Carbapenems was the most active antibiotics for gram negative bacill,and vancomycin for gram positive cocci.Conclusion Infectious bacteria have high selectivity to the sensitive antibiotics,and doctors should carefully use antibiotic according to the susceptibility test results in order to reduce hospital infection and the emergence and spread of resistant strains.

Objective To investigate the role of pancreatic β cell on pancreatic regeneration following experimental acute pancreatitis.Methods Eighty-seven SD male rats were randomly divided into four groups:control group ( n =15 ),STZ group ( n =24),L-Arg group ( n =24 ),STZ + Arg group ( n =24).60 mg/kg of STZ was administrated by intraperitoneal injection to induce the diabetes model.2.5 g/kg body weight of LArg was administrated by intraperitoneal injection to induce the acute pancreatitis model.The rats were sacrificed 1,3,5,7 d later and the serum levels of amylase and glucose were measured.Relative pancreatic weight (pancreatic weight/body weight) were measured.Pancreatic tissue underwent routine pathologic examination,and the percentage of area of necrosis and tissue transformation was calculated.The expression of Reg4 and insulin was performed by immunofluorescence.Results Serum level of glucose significantly increased after STZ injection.After L-Arg injection,serum level of amylase significantly increased,and there was pancreatic tissue edema,necrosis,infiltration of inflammatory cells,which suggested the successful model induction.The percentage of area of necrosis in STZ + L-Arg group was (71.6 ± 6.0) ％ at the 3rd day,which were significantly higher than (42.3 ± 4.0 ) ％ in L-Arg group; the percentage of area of transformation was (45.6 ± 5.4) ％,which were significantly lower than (78.5 ± 6.4) ％ in L-Arg group.Expression of Reg4 in pancreatic islets of STZ + L-Arg group was significantly lower than those in L-Arg group.Conclusions STZ impairs pancreatic β cells,aggravates pancreatic damage following L-arginine induced pancreatitis and inhibits pancreatic regeneration.

Objective To explore the expression of HCK gene during the cardiomyocyte differentiation of mouse embryonic stem cells and analyze the role of HCK gene in maintenance of pluripotency of embryonic stem cells.Methods Mouse embryonic stem cells were cultured,then induced to differentiate into cardiomyocytes.Total RNAs were isolated from mouse embryonic stem cells in the differentiation days:0 day(D0),the second day(D2),the fourth day(D4),the sixth day(D6),the eighth day(D8),respectively.The levels of HCK mRNAs were assessed by the method of semi-quantitive reverse transcriptase-polymerase chain reaction(RT-PCR).In the meanwhile,Total proteins were also isolated from mouse embryonic stem cells in the differentiation D0,D2,D4,D6,D8,and the levels of HCK proteins were evaluated by Western-blot.Results HCK mRNAs could be detected in the mouse embryonic stem cells in D0 and D2,however,they were undetectable from D4 to D8.The expression of HCK mRNAs was rapidly down-regulated during cardiomyocyte differentiation of mouse embryonic stem cells.Expression of HCK proteins,which coincided with HCK mRNAs,down-regulated during differentiation and couldn't be detected in D4.Conclusions With the cardiomyocyte differentiation of mouse embryonic stem cells,the expression of HCK in the levels of mRNA and proteins are sharply down-regulated;HCK may play an important role in maintaining the pluripotency of embryonic stem cell.

An on-line two dimensional liquid chromatographic (2D-LC) method was established by using an ultimate dual gradient liquid chromatography, three chromatographic columns and valve-switching technology to detect 2460A in trichoderma hazianum fermentation liquor. MF C8 column (10 mm×4. 6 mm, 5. 0 μm) was used as purification column and MG C18 column (20 mm×4. 6 mm, 5. 0 μm) was used as enriching column. Methanol and water were used as mobile phase with a gradient elution at a flow rate of 2. 0 mL/min. The sample was separated on the Thermo Hypersil GOLD C18 column (250 mm×4. 6 mm, 5. 0μm) maintained at 40 ℃ using methanol and water. The flow rate was 1. 0 mL/min and 1. 0 mL sample was injected into the 2D-LC system. The detection wavelength was 424 nm. The whole analytical time was less than 60 min. The standard curve was linear over the 2460A concentration range of 0. 0025-10. 0 mg/L(r=0. 9981, n=8). The limit of detection was calculated to be 1 . 2μg/L ( S/N=3 ) and the limit of quantification was calculated to be 2 . 5 μg/L ( S/N=10 ) . The average recoveries varied from 88 . 0% to 104 . 4%.

Objective To observe the protective and anti-apoptosis effects of Rannasangpei (RNSP) on brain ischemia and reperfusion injury in rats. Methods Middle cerebral artery occlusion (MCAO) model was established and the groups were divided as sham group, MCAO group, vehicle + MCAO group and RNSP + MCAO group. Neuronal deficient signs, brain infarct area, the ratio of Bcl-2/Bax and the expression of caspase-3 were evaluated by neuronal deficient score, TTC (2,3,5-Triphenyltetrazolium chloride) staining and Western blot respectively. Results Compared with those parameters in sham group, the neuronal deficient signs, infarct area and caspase-3 expression increased evidently while the ratio of Bcl-2/Bax decreased markedly in MCAO group. But in RNSP+MCAO group, the neuronal deficient signs, infarct area and cas?pase-3 expression decreased greatly while the ratio of Bcl-2/Bax increased markedly compared with those parameters in MCAO group. Conclusion RNSP may have protective effects on brain ischemia and reperfusion, which is related to its an?ti-apoptosis role indicated by upregulation of Bcl-2/Bax ratios and downregulation of caspase-3.
