Objective To study the drug resistance of neonatal sepsis caused by Klebsiella pneumoniae and provide evidence for drug treatment. Method Retrospectively analysis was conducted on the clinical data and antibiotic resistance of Klebsiella pneumoniae in 50 neonates with sepsis. Results The majority of the 50 cases were infected in hospital. There were 13 ESBLs strains in 50 Klebsiella pneumoniae strains (26%), and the others were negative ESBLs starins (74%). All the strains were multidrug-resistance to the β-lactam antibiotics and only sensitive to few antibiotics such as Imipenem and Amikacin. The sensitive rate was 100%. Conclusions The first selected antibiotic for the treatment of neonatal sepsis caused by Klebsiella pnemoniae was Imipenem or Amikacin.

Objective To investigate the affect of body positions on biochemical indexes. Methods By autogenous contrast and cross matched survey, 107 volunteers divided into 3 season patches of winter, spring and summer, blood samples were drawn from the same part in both standing and lying positions。From19 persons, blood samples were collected respectively after standing and sitting for 15 min, lying for 15 min and 30 min and then sitting for another 15 min。 The blood samples were analyzed for 32 biochemical indexes on analyzer。Results 25 biochemical indexes in sitting position were significantly different from those in lying position (P0。05)。Conclusions Changing body position can result in obvious physiological variation of 28 biochemical indexes, particularly of those related to protein. Such result may lead to abnormality in some marginal values. It suggests body position should not be neglected in analyzing laboratory data.

Objective To investigate the immunological characteristics and clinical significance of reactive plasmacytosis in patients with severe fever with throbocytopenia syndrome (SFTS).Methods Bunyavirus-infected patients who were diagnosed with SFTS were collected from March 2015 to October 2015 in Taizhou Hospital.Morphology analysis of bone marrow and peripheral blood (PB) smear, as well as flow cytometry analysis of plasma cell immune phenotype from peripheral blood were conducted.Serum immunoglobulin levels and helper T hymphocytes (Th)1/Th2 cytokine expressions were detected.Mann-Whitney U test was used.Results PB plasma cells from all of the SFTS patients increased in varying degrees, and the phenotype of the plasma cells was CD19+CD38++CD45+CD138+, which indicated normal mature plasma cells.The ratio of PB plasma cells was >0.030 in 10/16 patients, and >0.300 in 2/16 patients.The ratios of PB plasma cells in the patients with severe and critical groups were significantly higher than that in the mild group (0.052 vs 0.016, P<0.05).Monocytoid histiocytes and hemophagocytes were observed in the BM morphology of 9 patients.Three of them were diagnosed as hemophagocytic lymphohistiocytosis (HLH).The ratio of plasma cells was more than 0.030 in the bone marrow of 8 patients.The serum levels of interlewkin (IL)-6, IL-10 and interferon (IFN)-γ in acute phase were significantly elevated with the median level of 49.75 ng/L, 26.98 ng/L (reference value 2.6 to 4.9 ng/L) and 17.57 ng/L, respectively.While the levels of IL-2, IL-4 and twmor necrosis fautor(TNF)-α were not significantly changed.The serum IL-6 and IL-10 levels in the patients with severe and critical groups were both significantly higher than those in the mild group (IL-6: 132.36 vs 22.81 ng/L;IL-10: 75.28 vs 6.33 ng/L, both P<0.05), but the difference of IFN-γ level was not significant (P>0.05).The serum IgG, IgA and IgM levels did not increase in acute stage, with the median of 11.6 g/L, 2.56 g/L and 1.60 g/L (reference value 0.46 to 3.04 g/L), respectively.Conclusion The patients with SFTS show excessive humoral and cellular immunity, and the severity of disease is positively correlated with the ratio of peripheral plasma cells and the levels of cytokines IL-6 and IL-10.

Objective To investigate the morphological factors related to the rupture of very small (≤3mm) anterior communicating artery (AComA) aneurysms, which provides basis for decision-making of whether or not taking intervention in very small un-ruptured AComA aneurysms. Methods (1) One hundred patients with primary AComA aneurysms, admitted to our hospital from January 2008 to June 2013, were enrolled; 84 AComA aneurysms were ruptured while 16 were un-ruptured; the morphological parameters of aneurysms were obtained by three-dimensional reconstruction with CT angiography (CTA) of the patients, and the clinical data and aneurysm morphological parameters were compared between the ruptured aneurysm group and the un-ruptured aneurysm group; multivariate Logistic regression was used to analyze the risk factors of small aneurysm rupture in the AComA, and receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of size ratio (SR) of maximum tumor depth to proximal carrier artery diameter in rupture of small aneurysms in the AComA. (2) Ninety-nine patients with primary AComA aneurysms, admitted to our hospital from June 2013 to January 2016, were enrolled; the parameters from the above analyses were applied to these patients to verify their predictive effectiveness. Results (1) Perpendicular height, AR value (Height/Neck), SR value and vessel angle were significantly different between ruptured aneurysm group and un-ruptured aneurysm group (P<0.05); multivariate Logistic analysis indicated that SR value was the independent risk factor of rupture of very small AComA aneurysms (OR=4.201, 95％CI: 1.175-15.019, P=0.012), and the lager the SR value, the higher the risk of rupture; ROC curve analysis revealed that the area under the curve was 0.699 with the optimal cut-off value being 0.9, and its diagnostic sensitivity, specificity and accuracy was 0.786, 0.625 and 0.760, respectively. (2) The SR value was then applied to the 99 patients, showing a stable predictive potential with sensitivity, specificity and accuracy of 0.676, 0.714 and 0.687, respectively. Conclusion SR value (≥0.9) is identified as independent morphological risk factor for rupture of very small AComA aneurysms; SR value is closely related to the state of aneurysms, which help make a better individualized and effective decision on the treatment of very small AComA aneurysms in clinic.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

Objective To determine clinical features and rupture risk of anterior communicating artery (AComA) aneurysms in different age groups. Methods The clinical data of 519 consecutive patients with AComA aneurysms in the First Affiliated Hospital of Wenzhou Medical University between December 2007 and February 2015 were reviewed and divided into younger group (<65 years) and older group (≥65 years). The clinical characteristics and aneurysm morphologies were compared between the two groups. Results There were 390 aneurysms in younger group, and 129 in older groups. For the younger group, hypertension,the size of the aneurysms, maximum height, perpendicular height, size ratio (SR), aspect ratio (AR), aneurysm angle, A1 segment configuration, morphology showed significantly differences in ruptured aneurysms group compared with those in unruptured aneurysms (P<0.05). The multivariate analysis showed that significant difference between the two groups was aneurysm size ( OR＝1.461,95% CI 1.027-2.079, P＝0.035). For the older group, there were statistically significant differences in hypertension,size of the aneurysms, maximum height, perpendicular height, SR, aneurysm angle, vessel size and the distribution of aneurysm projection between the ruptured aneurysms group and unruptured aneurysms group (P<0.05). The multivariate analysis showed that SR ( OR＝11.516,95% CI 1.782-74.445,P＝0.01) was the only significant predictor of aneurysm rupture. Between the younger and older groups,the distributions of sex, hypertension, smoke, vessel size and SR were statistically significant (P < 0.05). Conclusions For younger people, the males who smoked are more likely to have AcomA aneurysms and the size of the aneurysms is independent risk of aneurysm rupture. For older people, the females with hypertension also more often have AcomA aneurysms and the SR is independently associated with aneurysm rupture.

Objective To investigate the incidence and predictors of cerebral infarction in patients with ruptured ACoA aneurysms, and to provide diagnostic and therapeutic information.Methods A total of 319 patients with ruptured ACoA aneurysms in our hospital from January 2009 to February 2015 were reviewed in this study. The author collected data regarding clinical characteristics, and measured the aneurysm morphologies on CTA images. Age, flow angle, vessel angle were analyzed by independent-samples t tests in patients with or without cerebral infarction. Mann-Whitney U tests were used for aneurysm size, aneurysm height, perpendicular height, neck size, size ratio, aspect ratio, aneurysm angle , World Federation of Neurosurgical Societies (WFNS) grade at admission and Fisher grade. Chi-square tests and Fisher's exact tests were used for sex, histories of hypertension, smoking and stroke, treatment modalities, anterior cerebral A1 segment configuration and angiographic vasospasm on CTA images. The multivariate logistic regression analyses were used to determine the independent risk factors of cerebral infarction using the stepwise regression method. Results Of the 319 patients, there were 253 without and 66 patients with cerebral infarction. Differences of age(53±11 vs 57±12,respectively;t=-2.415, P=0.016), Fisher grade [Ⅰ 23(9.1%), Ⅱ 27(10.7%), Ⅲ 74(29.2%), Ⅳ 129(51.0%) vs Ⅰ 1(1.5%), Ⅱ 7 (10.6% ), Ⅲ 13(19.7% ), Ⅳ 45(68.2% ), respectively;Z=-2.541, P=0.035] and treatment modalities [endovascular coil embolization 155(61.3% ), neurosurgical clipping 98(38.7% ) vs endovascular coil embolization 23(34.8%), neurosurgical clipping 43(65.2%), respectively;χ2=14.810, P<0.001] reached statistical significance. Multivariate analysis showed that Fisher grade Ⅳ(OR=10.36,95%CI 1.34-80.29, P=0.025) and neurosurgical clipping (OR=3.28, 95% CI 1.84-5.86,P<0.001)still had statistical significance. Conclusions Cerebral infarction in patients with ruptured ACoA aneurysms may be associated with Fisher grade and treatment modalities. Although there is difference between the two groups in age, it is not a predictor of the occurrence of cerebral infarction.

As the smallest combination unit of Chinese medicinals， herbal pairs serve as the bridge between medicinals and formulas， whose combination theory reflects the basic characteristics of Chinese medicinals combination and the core essence of prescription composition. Simultaneously， as a key combination of medicinals in clinical treatment of diseases， syndromes， and symptoms， herbal pairs are the main form of clinical medication in traditional Chinese medicine （TCM） as well as the characteristic advantage of treating diseases. This article summarized that “mutual complement of medicinals of same or antagonism flavor and nature” theory is the theoretical origin， and efficacy-enhancement and toxicity-attenuation is the core purpose of the combination of herbal pairs. The property theory of Chinese medicinals and the thought of differentiation and treatment are the main basis of the combination of herbal pairs， and pertinence and flexibility are the key points in clinical application. All mentioned above are expected to provide theoretical guidance for the clinical use and modern research of herbal pairs.
