Objective To investigate the mortality and cause of death in inpatients with cerebral infarction. Methods The clinical data of 515 patients with cerebral infarction as the underlying cause of death from January 2005 to December 2009 were analyzed retrospectively. The hospital mortality, direct cause of death,and constituent ratio of the cause of death were calculated. The clinical features,such as classification of the Trial of Org 10 172 in acute stroke treatment( TOAST),age and duration of hospital-ization were analyzed. Results ( 1 )The hospital mortalities in patients with cerebral infarction from 2005 to 2009 were 2. 0%(91/4 659),2. 1%(110/5 264),1. 9%(95/5 035),1. 2%(100/8 656),and 1. 0%(119/11 640),respectively. The overall mortality rate was 1. 5%(515/35 254),basically had a declining trend year by year(χ2 =42. 39;P<0. 01).(2)The mortalities of the inpatients with cerebral infarction in the young( <45 years),middle-aged(45 to 59 years),elderly(60 to 74 years),and aged ( >74 years)groups were 1. 1%( 22/2 009 ),1. 0%( 112/11 158 ),1. 5%( 221/14 311 ),and 2. 1%(160/7 776),respectively. They increased with increasing age(P<0. 01).(3)The TOAST classification in 515 died patients were as follows:57. 3%(n=295)for large-artery atherosclerosis,19. 4%(n=100) for cardioembolism,14. 4%(n=74)for cryptogenic stroke,7. 0%(n=36)for small-artery occlusion and 1. 9%(n=10)for other reasons. The five leading direct cause of death were cerebral hernia 49. 3%(n=254),primary central respiratory and circulatory failure 25.0%(n=129),pneumonia 8. 9%(n =46), cerebral-cardiac syndrome 5. 8%( n =30 ),and multiple organ failure 5. 6%( n =29 ).( 4 ) The mean age of death was 67 ± 12 years old. The patients who died of cerebral hernia and primary central respiratory and circulatory failure were younger than those who died of pneumonia(65 ± 13,68 ± 11,and 75 ± 10,respectively;all P<0. 01). The median length of hospital stay was 3 days. The length of hospital stay in patients who died of hernia,primary central respiratory and circulatory failure,and cerebral-cardiac syndrome were significantly shorter than those who died of pneumonia and multiple organ failure( the median length of hospital stay was 3. 0,3. 0,3. 0,12. 5,and 9. 0 days,respectively;all P <0. 05). Conclusions The mortality of hospitalized patients with cerebral infarction have a declining trend year by year. Brain disease itself is the most important reason of early death for patients with cerebral infarction, indicating that it is the important point of prevention and treatment in clinical work.

OBJECTIVETo observe and evaluate the clinical effect of acupuncture at "Siguan" combined with the Gallbladder Meridian acupoints on migraine.

METHODSWith randomized controlled trial design, 87 patients were randomly divided into an observation group (42 cases) and a control group (45 cases). The observation group was treated with acupuncture at "Siguan" including Hegu (LI 4) and Taichong (LR 3), combined with the Gallbladder Meridian acupoints including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40) and Zulinqi (GB 41), while the control group was treated with acupuncture at the Gallbladder Meridian acupoints, including Fengchi (GB 20), Shuaigu (GB 8), Qiuxu (GB 40), Zulinqi (GB 41), Yanglingquan (GB 34) and Hanyan (GB 4). The treatment was given every other day in two groups, 3 times per week for totally 6 weeks. The migraine intensity, migraine frequency and lasting time of each migraine were observed before and after treatment, and 3-month follow-up was performed after treatment. The clinical efficacy in two groups was evaluated.

RESULTSCompared with those before treatment, the migraine intensity, frequency and lasting time were all reduced significantly after treatment in the two groups (all P<0.01), which were more obvious in the observation group (all P<0.05). At the end of the treatment, the total effective rate was 95.2% (40/42) in the observation group and 80.0% (36/45) in the control group, which had statistical difference (P<0.05). After 3-month follow-up, the total effective rate was 88.1% (37/42) in the observation group and 75.6% (34/45) in the control group, which had no statistical difference (P>0.05).

CONCLUSIONThe "Siguan" combined with the Gallbladder Meridian acupoints could significantly relieve the migraine intensity, frequency and lasting time, and its improvement of symptoms and short-term efficacy are superior to those of the Gallbladder Meridian acupoints alone.

OBJECTIVE: To establish an HPLC method to determine the dissolutions of felodipine and metoprolol tartrate in compound felodipine controlled release tablets. METHODS: An HPLC method was established with Agilent Eclipse C18 column (4.6 mm×250 mm, 5 μm).A mixture of 0.3% SDS (pH adjusted to 2.5 with phosphoric acid)-acetonitrile-methanol V:V:V(40:50:10) was used as the mobile phase. The column temperature was 25°C. The flow rate was 1 mL·min-1 and the detection wavelength was set at 233 nm. RESULTS: The relative retention time of felodipine and metoprolol tartrate was 6.20 and 8.45 min respectively. The linear ranges of these two drugs were 1-24 μg·mL-1 (r=0.9999) and 10-240 μg·mL-1 (r=0.9999). The average recoveries of felodipine and metoprolol tartrate were 99.99% and 99.91% respectively. The RSDs of this method were all less than 2%. CONCLUSION: The established method is sensitive, accurate and reliable for determination of the dissolutions of felodipine and metoprolol tartrate in compound felodipine controlled release tablets.

Objective To investigate the correlation between immature granulocyte and CD34+ cells, mononuclear cells (MNC) in donor's peripheral blood by recombinant human granulocyte colony-stimulating factor (rhG-CSF). Methods The stem cell were mobilized by rhG-CSF 7.25-10 μg·kg-1·d-1 from 122 allo-PBSCT donors. Before and after mobilization, to test CD34+ cells of peripheral blood stem cell graft and number of MNC, immature granulocyte, CD34+ cell per patient' weight were calculated. Results White blood cell count and immature granulocyte gradually increased, and reached the peak on the frith day. There was a good relationship between increased immature granulocytes and increased CD34+ cells. The patients all achieved completed donor engraftment and achieved hematopoietic recovery. The chromosome, blood type and HLA type were transformed to be donor's type. Ph1 changed to be negative in CML patients. Conclusion rhG-CSF (7.25～10 μg·kg-1·d-1) had a good effect to mobilize PBSC. There was a good relationship between in-creased immature granulocytes and increased CD34+ cells after mobilization by rhG-CSF. The number of immature granulocytes can reflect indirectly the count of stem/progenitor, so the MNC and immature granulo-cytes can become a threshold of dosage standard.

Objective To investigate the expressions of receptor for advanced glycation endproducts (RAGE) and nuclear factor κB(NF-κB) in brain hippocampus of rat with chronic fluorosis,and to reveal the mechanism of brain damage resulted from chronic fluorosis.Methods Sixty clean grade SD rats were randomly divided to three groups(20 rats in each group,10 female and 10 male) fed with different contents of fluoride,control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group(10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group(50 mg/L fluoride) for six months.Then the rats were killed by femoral artery bleeding and hippocampus was removed.Protein and mRNA levels of RAGE and NF-κB in the hippocampus were determined by Western blotting and quantitative real time PCR,respectively.Results As compared to the control groups[(100.00 ± 2.60)％,(100.00 ± 7.80)％],the expressions of RAGE and NF-κB at protein level in the hippocampus were significantly increased in the small dosage of fluoride exposure groups [(205.00 ± 15.30)％,(156.00 ± 12.20)％] and the large dosage of fluoride exposure groups[(232.00 ± 10.90)％,(162.00 ± 9.80)％,all P ＜ 0.05]; for the mRNA level of RAGE and NF-κB,the expressions were higher in the small dosage of fluoride exposure groups(1.27 ± 0.09,0.83 ± 0.15) and the large dosage of fluoride exposure groups (2.60 ± 0.19,1.27 ± 0.19) than those of the control groups(0.66 ± 0.18,0.32 ± 0.08,all P＜ 0.05).Conclusions The increased expressions of RAGE and NF-κB in the hippocampus of rat brain are caused by chronic fluorosis,and these changes may be associated with the mechanism of nerve injury.

Objective Aim of the study is to investigate the expression of syndecan-4 and nuclear factor κB(NF-κB) in the kidney of rat with chronic fluorosis,and to reveal the mechanism of kidney damage resulted from the toxicity of excessive amount of fluoride.Methods According to body mass and sex,sixty SD rats were randomly divided to three groups according to body mass and fed with different contents of fluoride:control group with normal tap-water(＜ 0.5 mg/L fluoride),small dosage of fluoride exposure group (adding 10 mg/L fluoride in tap-water) and large dosage of fluoride exposure group (50 mg/L fluoride) for six months.The protein level of syndecan-4 and NF-κB in the kidney was detected by Western blotting and syndecan-4 mRNA level by quantitative real time PCR.Results As compared to the control group[(100.0 + 8.1)％],the expression of syndecan-4 at protein level in the kidney of rat was significantly increased in the small dosage of fluoride exposure group [(198.5 + 5.6)％,P ＜ 0.05] and large dosage of fluoride exposure group [(209.2 + 13.0)％,P ＜ 0.05]; the protein levels of NF-κB in the small dosage of fluoride exposure group[(284.4 + 11.1)％,P ＜ 0.05] and in the large dosage of fluoride exposure group[(343.2 + 2.9)％,P ＜ 0.05] were significantly increased than that of the control group[(100.0 ± 10.7)％].The mRNA levels of syndecan-4 in the kidney in the small dosage of fluoride exposure group and large dosage of fluoride exposure group(0.431 + 0.058 and 0.453 ± 0.065,both P ＜ 0.05,respectively) were significantly increased than that of the control(0.128 + 0.026).Conclusions The increased expression of NF-κB in the kidney is induced by increased expression of syndecan-4,which may be involved in kidney damage of chronic fluorosis.

Objective To investigate the detection of respiratory tract virus from throat swabs of patients with lower respiratory tract infection(LRTI)in a hospital,so as to provide reference for clinical diagnosis and treatment. Methods Throat swabs of hospitalized children with LRTI between May 2103 and April 2014 were detected by di-rect immunofluorescence assay,infection/carriage of respiratory syncytial virus(RSV),adenovirus(ADV),influen-za virus A(IV-A),IV-B,parainfluenza virus 1(PIV-1),PIV-2,and PIV-3 in children were surveyed.Results Of 8 425 throat swab specimens of hospitalized patients,1 879 were detected virus,the total detection rate was 22.30%,detection rate of RSV was the highest (11 .31 %),followed by PIV-3(4.37%).There was no significant difference in the total detection rate of respiratory tract virus between children of different genders (P =0.051).Of all age groups,detection rate of RSV in infants and young children was the highest,the detection rates of 7 kinds of virus from preschool children were approximate,detection rate of ADV from primary school children was the high-est (37.50%).In spring and winter,children mainly infected with RSA,accounting for 62.82% and 69.88% re-spectively;in summer,PIV-3 was the predominant virus,accounting for 41 .47%,in autumn,there was little difference in the percentage of each virus.Conclusion The detection rate of 7 kinds of virus isolated from throat swabs of hospitalized children with LRTI is related to age and season;the detection rate of 7 kinds of virus from in-fants and young children is high,RSA is the main virus.
