It is unanimously accepted that stroke is a highly heterogeneous disorder.Different subtypes of ischemic stroke may have different risk factors,clinical features,and prognoses.The aim of this study was to evaluate the risk factors,clinical characteristics,and prognoses of different subtypes of ischemic stroke defined by the Trial of ORG10172 in Acute Stroke Treatment (TOAST) criteria.We prospectively analyzed the data from 530 consecutive patients who were admitted to our hospital with acute ischemic stroke within 7 days of stroke onset during the study period.Standardized data assessment was used and the cause of ischemic stroke was classified according to the TOAST criteria.Patients were followed up till 30 and 90 days after stroke onset.It was found that large-artery atherosclerosis was the most frequent etiology of stroke (37.4%),and showed the highest male preponderance,the highest prevalence of previous transient ischemic attack,and the longest hospital stay among all subtypes.Small artery disease (36.4%) was associated with higher body mass index,higher plasma triglycerides,and lower plasma high-density lipoprotein cholesterol than cardioembolism.Cardioembolism (7.7%),which was particularly common in the elderly (i.e.,individuals aged 65 years and older),showed the highest female preponderance,the highest prevalence of atrial fibrillation,the earliest presentation to hospital after stroke onset,the most severe symptoms on admission,the maximum complications associated with an adverse outcome,and the highest rate of stroke recurrence and mortality.Our results suggest that ischemic stroke should be regarded as a highly heterogeneous disorder.Studies involving risk factors,clinical features,and prognoses of ischemic stroke should differentiate between etiologic stroke subtypes.

In vitro neuraminidase inhibition assays and ultrafiltration liquid chromatography with diodearray detector coupled to time of flight mass spectrometer (UPLC-DAD-TOF-MS) were combined to screen bioactive compounds inhibiting neuraminidase from Isatidis Radix. By comparing the compounds from Isatidis Radix before and after ultrafiltration, we found that arginine, goitrin and adenosinea can bind with neuraminidase, and the binding degree of the three compounds were (36.23 +/- 1.12)%, (32.54 +/- 1.02)% and (9.38 +/- 0.47)%, respectively. The IC50 of arginine and goitrin were (1.16 +/- 0.02), (1.20 +/- 0.02) g x L(-1), respectively. While the IC50 of adenosinea was higher than 500 g x L(-1). The results showed that arginine and goitrin might be the main compounds with antiviral activity of Isatidis Radix. This study may provide a useful method for the screening of bioactive compounds and quality control of Isatidis Radix.

OBJECTIVETo introduce our experience in diagnosis and treatment of 33 patients with Tessier craniofacial clefts.
METHODS33 patients with craniofacial clefts were classified by Tessier classification. According to the type and severity of the clefts, various techniques, from simple local flap transfer to complicated osteotomy and bone grafting were used to correct the deformity in 29 patients.
RESULTSAll patients who underwent corrective operation were satisfied with the result, and there were no complications.
CONCLUSIONS(1) Tessier classification is very important for plastic surgeon to find potential craniofacial deformities related to main signs. (2) No. 7 cleft is one of most common Tessier craniofacial clefts. (3) Each Tessier cleft is unique, therefore, the treatment plans cannot be standardized. Specific corrective operation must be performed on each patient according to the type and severity of the cleft, including simple local flap transfer to complicated osteotomy and bone grafting or distraction osteogenesis.

OBJECTIVETo investigate the role of releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus in the correction of the congenital blepharoptosis.
METHODSTwenty-seven patients with 40 eyes of blepharoptosis were undergoing the treatment. It was performed by releasing the fibrous bundles across the levator muscle between the medial canthus and lateral canthsus near the top of tarsus to correct the mild and moderate blepharoptosis. A further procedure can also be added to by folding the levator aponeurosis if necessary. In the severe blepharoptosis, the frontalis aponeurose flap may be applied for the suspension as well during the operation.
RESULTSOf the 40 eyes in 27 cases with mild, moderate and severe blepharoptosis were treated by using this method, with 38 eyes corrected satisfactorily and 2 eyes corrected mostly in the following-ups from 3 months to 1 year.
CONCLUSIONThe above mentioned technique may be a good, simple and effect method to corret congenital blepharoptosis.

OBJECTIVETo research the correlation between surgical treatment for atlantoaxial dislocation and dredging Governor vessel.
METHODSFrom June 2004 to June 2010,113 patients were reviewed, including 65 males and 48 females, with the mean age of 42.6 years (ranged, 8 to 64 years). All the patients were classified and treated by TOI clinical classification which included traction and decompression and reduction, and inter fixation fusion by surgery. The SAC (space available for the cord), Governor vessel Yuzu score, JOA score, NDI score (cervical spine dysfunction index) before treatment were compared with those of after treatment.
RESULTSThe SAC in each group before treatment were (13.34 +/- 3.21), (10.43 +/- 2.42), (7.89 +/- 3.14), (10.50 +/- 0.71) mm respectively, the last follow-up of (16.02 +/- 1.42), (15.34 +/- 1.87), (14.49 +/- 1.58), (12.50 +/- 0.71) mm; Governor vessel Yuzu score before treatment were (8.37 +/- 1.87), (6.87 +/- 1.35), (5.17 +/- 1.13), (7.50 +/- 0.71) respectively, the last follow-up of (10.59 +/- 0.94), (10.25 +/- 1.01), (8.41 +/- 1.31), (9.0 +/- 0); JOA, NDI score significantly improved compared with that of before treatment.
CONCLUSIONAtlantoaxial dislocation confirmed and treated by TOI clinical classification can effectively relieve the nerve function and Governor vessel Yuzu syndrome, and show that surgical treatment is closely related with dredging the Governor vessel.

Objective To predict the monthly reported echinococcosis cases in China with the autoregressive integrated mov-ing average(ARIMA)model,so as to provide a reference for prevention and control of echinococcosis. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported echinococcosis cases of time series from 2007 to 2015 and 2007 to 2014,respectively,and the accuracies of the two ARIMA models were compared. Results The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2015 was ARIMA(1,0,0)(1,1, 0)12,the relative error among reported cases and predicted cases was-13.97%,AR(1)=0.367(t=3.816,P<0.001),SAR (1)=-0.328(t=-3.361,P=0.001),and Ljung-Box Q=14.119(df=16,P=0.590).The model based on the data of the monthly reported cases of echinococcosis in China from 2007 to 2014 was ARIMA(1,0,0)(1,0,1)12,the relative error among reported cases and predicted cases was 0.56%,AR(1)=0.413(t=4.244,P<0.001),SAR(1)=0.809(t=9.584, P<0.001),SMA(1)=0.356(t=2.278,P=0.025),and Ljung-Box Q=18.924(df=15,P=0.217).Conclusions The different time series may have different ARIMA models as for the same infectious diseases.It is needed to be further verified that the more data are accumulated,the shorter time of predication is,and the smaller the average of the relative error is.The estab-lishment and prediction of an ARIMA model is a dynamic process that needs to be adjusted and optimized continuously accord-ing to the accumulated data,meantime,we should give full consideration to the intensity of the work related to infectious diseas-es reported(such as disease census and special investigation).

OBJECTIVETo retrospectively analyze the curative effects and prognostic factors of HLA-matched sibling donor allogeneic hematopoietic stem cell transplantation (allo-HSCT) for chronic myelogenous leukemia patients (CML).
METHODSOf the 35 CML patients, 26 were males and 9 were females, with a median age of 32 (12 - 50) years. 30 patients were in chronic phase of CML, 5 patients were in accelerated phase. Allo-HSCT from HLA identical siblings was performed for 35 patients, of whom 11 received bone marrow transplantation (BMT) and 24 peripheral blood stem cell transplantation (PBSCT). Conditioning regimens was TBI (total-body irradiation) + CY (CTX) protocol in 8 patients and BU/CY protocol in 27 patients. The average follow-up was 48 months (range 7 - 108 months).
RESULTS34 (97.1%) patients were successfully engrafted. Among them, 21 patients (60.0%) had three years disease-free (DFS) survival. The overall 5-year survival (OS) was 57.1%. Two patients (5.7%) relapsed. Transplant-related mortality occurred in 12 patients. Hemorrhagic cystitis (HC) occurred in 5 patients and HVOD was observed in 1 patient. Acute graft-versus-host disease (aGVHD) occurred in 18 patients (51.4%), among them 7 patients (20.0%) were of grade III-IV. Chronic GVHD was in 17 patients (48.5%). There was no significant difference in 3-years DFS between BMT group and PBSCT group (54.5% vs. 62.5%, P > 0.05). The 3-year disease-free survival (DFS) was 42.9% in TBI/CY group and 55.6% in BU/CY group (P > 0.05). In univariate prognostic analysis model, the DFS at 3 years is 75% and 47.4% for < or =30 years patients and >30 years patients, respectively, P < 0.05. The 3-year DFS of patients with first chronic phase is higher than patients with advanced diseases (61.3% vs. 40%, P < 0. 05). The 3-year DFS in patients of grade I - II GVHD was higher than that in patients of grade III-IV GVHD (81.8% vs. 14.3%, P < 0.05).
CONCLUSIONThe patients who had transplantation done within 1 year after diagnosis during their first chronic phase of disease and who had low-grade GVHD have better prognosis. Those patients who had III-IV acute GVHD are prone to incorporate severe infection, which was a worse prognostic factor of allo-HSCT for chronic myelogenous leukemia.

OBJECTIVE:
To understand the relationships of daily average temperature and relative humidity with outpatient visit frequency of patients with chronic obstructive pulmonary disease, and whether temperature and relative humidity have a lag effect.
METHODS:
The effects of daily average temperature, relative humidity, and their interaction in Lanzhou between January 2013 and December 2017 on the outpatient visit frequency of chronic obstructive pulmonary disease patients were analyzed using Poisson generalized linear regression model combined with distributed lag non-linear model.
RESULTS:
There was a non-linear relationship between the daily average temperature and the outpatient visit frequency of chronic obstructive pulmonary disease patients. Between -12 °C and -8 °C, the outpatient visit frequency increased gradually with the decrease of the daily average temperature, and the outpatient visit frequency of chronic obstructive pulmonary disease patients increased by 11.60% per 1 °C of temperature drop. The daily average relative humidity also presented a non-linear effect on the outpatient visit frequency chronic obstructive pulmonary disease patients. When the daily average relative humidity was in the range of 15%-28%, the outpatient visit frequency increased gradually with the decrease of relative humidity, and the outpatient visit frequency of COPD patients increased by 37.05% for every 1% decrease of relative humidity. A synergistic effect was found between air temperature and relative humidity on chronic obstructive pulmonary disease, that is, under different relative humidity, the effect of air temperature was different. When the daily average relative humidity ≤ 50% and the daily average temperature≤11 °C, the effect of air temperature was the most obvious. For every 1 °C drop in temperature, the daily out-patient visit frequency of the whole population increased by 12.68% (5.62% in males and 7.56% in females; 5.24% in population < 65 years and 14.74% in population ≥ 65 years). When the daily average relative humidity > 50% and the daily average temperature ≤ 11 °C, the daily outpatient visit frequency of the whole population increased by 9.00% for every 1 °C drop in temperature (< 65 years, 7.11%; ≥65 years, 10.93%). When the daily average temperature > 11 °C, the temperature had no effect on the daily outpatient visit frequency of chronic obstructive pulmonary disease patients under different relative humidity.
CONCLUSION
The presence of a certain extent of interaction is observed between daily average temperature and relative humidity. Low-temperature and dry environment (relative humidity ≤50%, temperature ≤11 °C) as well as low-temperature and high-humidity environment (relative humidity > 50%, temperature ≤11 °C) can both increase the risk of outpatient visit in chronic obstructive pulmonary disease patients.

INTRODUCTIONThis study aimed to evaluate compliance with and performance of the Canadian Computed Tomography Head Rule (CCHR), and its applicability to the Singapore adult population with minor head injury.
METHODSWe conducted a retrospective study over six months of consecutive patients who presented to the adult emergency department (ED) with minor head injury. Data on predictor variables indicated in the CCHR was collected and compliance with the CCHR was assessed by comparing the recommendations for head computed tomography (CT) to its actual usage.
RESULTSIn total, 349 patients satisfied the inclusion criteria. Common mechanisms of injury were falls (59.3%), motor vehicle crashes (16.9%) and assault (12.0%). 249 (71.3%) patients underwent head CT, yielding 42 (12.0%) clinically significant findings. 1 (0.3%) patient required neurosurgical intervention. According to the CCHR, head CT was recommended for 209 (59.9%) patients. Compliance with the CCHR was 71.3%. Among the noncompliant group, head CT was overperformed for 20.1% and underperformed for 8.6% of patients. Multivariate logistic regression analysis revealed that absence of retrograde amnesia (odds ratio [OR] 4.1, 95% confidence interval [CI] 1.8-9.7) was associated with noncompliance to the CCHR. Factors associated with underperformance were absence of motor vehicle crashes as a mechanism of injury (OR 6.6, 95% CI 1.2-36.3) and absence of headache (OR 10.8, 95% CI 1.3-87.4).
CONCLUSIONCompliance with the CCHR for adult patients with minor head injury remains low in the ED. A qualitative review of physicians' practices and patients' preferences may be carried out to evaluate reasons for noncompliance.

To investigate the therapeutic effect of Jingfang Granules on carbon tetrachloride(CCl_4)-induced liver fibrosis in mice and its mechanism. Forty-nine 8-week-old male C57 BL/6 J mice were randomly divided into a blank group, a CCl_4 group, a silybin group(positive control, 100 mg·kg~(-1))+CCl_4, a Jingfang high-dose(16 g·kg~(-1)) group, a Jingfang high-dose(16 g·kg~(-1))+CCl_4 group, a Jingfang medium-dose(8 g·kg~(-1))+CCl_4 group, and a Jingfang low-dose(4 g·kg~(-1))+CCl_4 group, with 7 mice in each group. The mice in the blank group and Jingfang high-dose group were intraperitoneally injected olive oil solution, and mice in other groups were intraperitoneally injected with 10% CCl_4 olive oil solution(5 mL·kg~(-1)) to induce liver fibrosis, twice a week with an interval of 3 d, for 8 weeks. At the same time, except for the blank group and CCl_4 group, which were given deionized water, the mice in other groups were given the corresponding dose of drugs by gavage once daily for 8 weeks with the gavage volume of 10 mL·kg~(-1). All mice were fasted and freely drank for 12 h after the last administration, and then the eyeballs were removed for blood collection. The liver and spleen were collected, and the organ index was calculated. The levels of alanine aminotransferase(ALT), aspartate aminotransferase(AST), total bile acid(TBA), and triglyceride(TG) in the serum of mice were detected by an automated analyzer. Tumor necrosis factor-α(TNF-α), interleukin-6(IL-6) and interleukin-1β(IL-1β) levels were detected by enzyme-linked immunosorbent assay(ELISA). Kits were used to detect the contents of superoxide dismutase(SOD), malondialdehyde(MDA), and glutathione(GSH) in the liver tissue. Pathological changes in the liver tissue were observed by hematoxylin-eosin(HE), Masson, and Sirius red staining. Western blot was used to detect protein expressions of transforming growth factor-β(TGF-β), α-smooth muscle actin(α-SMA) and Smad4 in the liver tissue. The results indicated that Jingfang Granules significantly reduced the organ index, levels of ALT, AST, TBA,TG, TNF-α, IL-6, and IL-1β in the serum, and the content of MDA in the liver tissue of mice with CCl_4-induced liver fibrosis. Jingfang Granules also significantly increased the content of SOD and GSH in the liver tissue. Meanwhile, Jingfang Granules down-regulated the protein levels of TGF-β, α-SMA, and Smad4. Furthermore, Jingfang Granules had no significant effect on the liver tissue morphology and the above indexes in the normal mice. In conclusion, Jingfang Granules has obvious therapeutic effect on CCl_4-induced liver fibrosis, and its mechanism may be related to reducing the expression of pro-inflammatory factors, anti-oxidation, and regulating TGF-β/Smad4 signaling pathway.
