Objective To investigate the changes and pathogenic significance of serum interleukin-12p70 (IL-12), intefferon-γ,(IFN-γ) and IL-4 in the course of hemorrhagic fever with renal syndrome(HFRS). Methods Twenty five eases were divided into mild group (14 eases) and severe group (11 cases) according to the severity of illness. Blood samples were collected in various stages(fever, hypotensian and oliguria,diuresis stage). Serum IL-12 and IFN-γ levels were determined by enzyme-linked immunoserbent assay(ELISA), IL-4 by radioimmunoassay (RIA), blood urea nitrogen (BUN) and platelet by automatic biochemical analyzer and blood analyzer. Results Serum IL-12 levels in mild and severe groups were significantly different during various stages of HFRS (F=5.765, P<0.01). The IL-12 level of both patient groups significantly increased(P<0.01) in fever[ (0.87±0.38), (1.08± 0.77)μg/L], hypotension and oliguria [ (0.77±0.21), (2.11±2.13)μg/L] ,and diuresis stage [ (1.42±1.10), (1.20±0.88)μg/L], compared with control group [(0.56±0.10)μg/L]. In various stages, IFN-γ levels of both case groups were respectively (8.04±13.05), (5.94±8.24), (15.95±18.05), (4.41±4.10), (1.09±1.24), (1.38±1.74), (1.12±1.26), (0.19±1.29)μg/L, and the difference was statistically significant compared with control [ (0.27±0.15)rig/L]. K,-4 levels did not change significantly in the stages(F=0.682, P0.05), while the ratios of IFN-γ and IL-4 contents in mild and severe cases were significantly higher than control [(0.36±0.26) μg/L] in fever[ (2.46±3.52), (16.92±22.77)p.g/L], hypotension and oliguria[(2.52±2.72), (1.77±2.06) μg/L],diuresis stage [(1.45±2.28), (2.32±3.98)μg/L], the difference had statically significant (P<0.05 or 0.01).The curve of IL-12 was similar to that of BUN, but was contrary to blood platelet count. Conclusions The elevated levels of IL-12 and IFN-γ, with the imbalance of Th1/Th2 might be the main cause of systemic inflammatoryresponse and involved in the pathogenesis of HFRS.

OBJECTIVETo discuss the replantation of fingertip amputation in lack of availability of intravenous anastomosis.
METHODSFrom November 2009 to November 2010, 86 patients (104 fingers) with fingertip amputation were treated with replantatioin, including 64 males and 22 females, with an average age of 26 years ranging from 2 to 64 years. The time from injury to therapy was from 30 min to 12 h, time of broken finger ischemia was from 2.5 to 12 h. Preoperative examination showed no obvious abnormalities. Four different replantation methods were selectively applied to these 104 amputated fingertips of 86 cases: (1) replantation with anastomosis of single or bilateral proper digital artery in 37 fingers; (2) replantation with arteriovenous bypass in 27 fingers; (3) replantation with exclusive anastomosis of digital artery in 24 fingers; (4) replantation with removing the palmar pocket method in 16 fingers.
RESULTSOne hundred and two of 104 amputated fingertips were survived. Among these survived fingers,75 cases (92 fingers) were followed-up for 6 to 24 months. According to the assessment standard of Chinese Medical Association of Hand Surgery, the results were excellent in 52 cases, good in 19, poor in 4.
CONCLUSIONIt benefits to expand the indications and improve the survival rate of replantation of fingertip amputation with the correct choice of different replantation methods according to the injury situation of the broken fingertip artery after debridement under the microscope.

Angiogenesis, the expansion of preexisting blood vessels, is a complex process required for tumor growth and metastasis. Although current antiangiogenic strategies have shown promising results in several cancer types, identification of additional antiangiogenic targets is required to improve the therapeutic response. Herein, we show that the microtubule-binding protein CLIP-170 (cytoplasmic linker protein of 170 kDa) is highly expressed in breast tumor samples and correlates positively with blood vessel density. Depletion of CLIP-170 significantly impaired vascular endothelial tube formation and sprouting in vitro and inhibited breast tumor growth in mice by decreasing tumor vascularization. Our data further show that CLIP-170 is important for the migration but not the proliferation of vascular endothelial cells. In addition, CLIP-170 promotes the polarization of endothelial cells in response to the angiogenic stimulus. These findings thus demonstrate a critical role for CLIP-170 in tumor angiogenesis and suggest its potential as a novel antiangiogenic target.

In daily medical work, most of the critically ill patients who cannot move by themselves are pulled and lifted by manpower, often relying on the cooperation of many doctors and nurses, which not only increases the risk of transfer and patients' discomfort, but also causes certain skeletal and muscle damage to the porters. The emergency department of the First Hospital of Jiaxing City, Zhejiang Province designed a kind of patient transfer device, and obtained the National Utility Model Patent (ZL 2018 2 0579844.X). The transfer device is composed of upper frame, lower frame and base. The upper frame and the lower frame are rectangular and in a horizontal position. The upper frame can slide laterally through the circular tubes which are fixed on the lower frame. The lower part of the base is provided with four universal foot brake wheels. During the usage, the booster frame facilitates the transfer of patients by the rolling and two sliding tracks of the circular tube, which can make patients move smoothly and comfortably, and reduce the working intensity of the transporter. This device has good practical value.

OBJECTIVETo provide theoretic warrant and technical reference for Salvia miltiorrhizr standardization planting, by carrying out various systemic studies such as observation of seeds configuration fabric, idiosyncrasy of water absorption and groping germinating conditions.
METHODIn the study of configuration fabric, seeds were observed and taken photos by scanning electronic microscope, and heft method was used for measuring changes of water absorption velocity and dehydration velocity. Seeds germination conditions were probed into under the national test regulations for crop seeds and related prescription from international standards.
RESULT(1) There was a layer of slime about 10-20 microm thickness covering epicarp of Danshen seeds. The slime formed as diamond meshwork (reseau) and the weight of it was 8%-10% of total seeds weight. (2) The speed of water absorption of seeds was extremely rapid. The weight of seeds could increase above 10 times as original while the dehydration velocity was quite low. (3) The optimal temperature for the seeds germination is around 25 degrees C, and the germination rate of the new seeds gained yearly was above 75%, but the rate would decrease sharply as years went by. It was also found that the seeds germination power and exponent of vigor were quite high under the temperature transformation between 23 degrees C, 28 degrees C. Such treatments as pre-cool, PEG treatment and infusing with GA3 could increase the rate of seeds germination capacity obviously.

Objective To demonstrate the current prevalence and treatment status of diabetes mellitus (DM) among inpatients with acute coronary syndrome (ACS) in China. Methods Sixty-four hospitals, including 32 secondary hospitals and 32 tertiary hospitals were selected for baseline survey. Fifty inpatients diagnosed with ACS were recruited consecutively from hospitals participated in this study. This paper focused on the prevalence and treatment status of DM among inpatients with ACS. Results (1)Clinical data of 3223 inpatients (average age 65±11 ) with ACS were collected during baseline survey,including 2183(67.7%) males and 1040(32.3%) females. Among them,39.8% were diagnosed as ST-segment elevation myocardial infarction ( MI), 9.2% as non-ST-segment elevation MI, 51.0% as unstable angina,and 27.1% with ACS history. (2) DM was found in 22.6% ACS patients. The prevalence rate of DM was higher in female (26.3%) patients than that in males (20.8%). The rate of DM was the highest(28.0%) in northeast area and lowest (17.7%) in southwest among 7 geographic districts (north, east,south,central,northeast,northwest and southwest parts of the country). Significant difference was observed among these areas. (3) Rate of awareness on DM was 73.1% among patients with DM, with significant differences among various areas. Treatment rate was 62.1% among patients with DM, with the highest(88.6%) seen in northwest and the lowest (78.4%) in central part of China. (4) Rates of prevalence(27.1%), awareness (82.3%) and treatment (86.7%) of DM were higher in recurrent ACS patients than in those without ACS history, Conclusion Nearly one-forth of the ACS inpatients were having DM, and 15% of the patients with known DM were not on anti-diabetic treatment. It is essential to pay more attention on the treatment of DM for the purpose of secondary prevention on cardiovascular disease.

Airway humidification is an important treatment for tracheotomy patients. At present, the commonly used methods of humidification are atomization inhalation, intra-tracheal drip, etc., but most of them have the disadvantages of interrupted humidification, inadequate humidification, repeated exposure of airway, increased nursing workload, etc. An improved disposable atomizer was designed by the emergency department of Jiaxing First Hospital in Zhejiang Province, which solved the above problems and obtained the National Utility Model Patent of China (ZL 2014 2 0406688.9). In the traditional atomizer, a make-up pipeline is added to run through the liquid container. The replenishing pipe is connected with an external infusion device. At the end of the pipeline inside the liquid container, a buoy with a guide rod is designed to continuously add liquid and automatically control the make-up speed. The device is driven by oxygen to perform airway humidification. The design can keep sufficient airway humidification, avoid frequent addition of humidification fluid, achieve the effect of increasing humidification, reducing the occurrence of complications, increasing the comfort of patients, and reducing the workload of nursing, and has a certain clinical value.

OBJECTIVE: To analyze the sociodemographic and clinical factors related to anxiety in patients with major depressive disorder (MDD). METHODS: This study involved a secondary analysis of data obtained from the Diagnostic Assessment Service for People with Bipolar Disorders in China (DASP), which was initiated by the Chinese Society of Psychiatry (CSP) and conducted from September 1, 2010 to February 28, 2011. Based on the presence or absence of anxiety-related characteristics, 1,178 MDD patients were classified as suffering from anxious depression (n=915) or non-anxious depression (n=263), respectively. RESULTS: Compared with the non-anxious group, the anxious-depression group had an older age at onset (t=-4.39, p<0.001), were older (t=-4.69, p<0.001), reported more lifetime depressive episodes (z=-3.24, p=0.001), were more likely to experience seasonal depressive episodes (chi2=6.896, p=0.009) and depressive episodes following stressful life events (chi2=59.350, p<0.001), and were more likely to have a family history of psychiatric disorders (chi2=6.091, p=0.014). Their positive and total scores on the Mood Disorder Questionnaire (MDQ) and the 32-item Hypomania Checklist (HCL-32) (p<0.05) were also lower. The logistic regression analysis indicated that age (odds ratio [OR]=1.03, p<0.001), a lower total MDQ score (OR=0.94, p=0.011), depressive episodes following stressful life events (OR=3.04, p<0.001), and seasonal depressive episodes (OR=1.75, p=0.039) were significantly associated with anxious depression. CONCLUSION: These findings indicate that older age, fewer subclinical bipolar features, an increased number of depressive episodes following stressful life events, and seasonal depressive episodes may be risk factors for anxiety-related characteristics in patients with MDD.

This study was conducted to define the taxonomic status of Spermophilus in the plague area of Dingbian County in Shaanxi Province, China, through the two-factor variance analysis of morphological characteristics, DNA barcoding, and chromosome karyotype analysis. The Spermophilus samples collected from Dingbian and Zhengxiang Baiqi Counties exhibited significant differences in their morphological measurements. All Spermophilus samples form two distinct branches in neighbor-joining (NJ) tree. One branch included the Spermophilus samples collected from Inner Mongolia, and the other branch included samples collected from the plague foci of Shaanxi Province and the Ningxia Region. The Spermophilus samples collected from Dingbian County had a chromosome number of 2n = 38 in 84.40% of all their cells. The Spermophilus species collected from the plague area of Dingbian County was categorized as Spermophilus alashanicus (S.alashamicus). The findings reported in this study are epidemiologically significant for monitoring plague in this region of west-central China.
