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.

Chinese Pharmaceutical Journal 2013;48(12):1015-1018
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.
