Hedging is an important component of vague language. This paper retrieves high frequency expressions of hedgingby using medical English corpus. Pragmatic functions of hedging are analyzed, which can be summarized as politeness principle, authors' self-protection, avoidance of the absolute, pursuit of objectiveness as well as conversational implication. To medical researchers, it is necessary to cultivate the awareness of hedging and learn how to adopt it in their research papers.

ObjectiveTo investigate the risk factors,prevention measures and treatment methods of the pulmonary fibrosis patients with nosocomial pulmonary fungal infection. Methods50 pulmonary fibrosis patients with nosocomial pulmonary fungal infection were chosen as the observation group. In the same time,50 pulmonary fibrosis patients without nosocomial pulmonary fungal infection were chosen as the control group. The following factors were compared: hospital stay, corticosteroid use, antibiotic use, invasive procedures, a merger of the underlying disease.ResultsThere were 46％ (23/50) patients had long-term use of antibiotics in the observation group, much more than the control group(26％ ,13/50) ,the difference was statistically significant( P ＜0.05) ;More than half of patients in both groups using glucocorticoids, the ratio in the observation group was 84％ (42/50), which was significantly higher than the control group( P ＜ 0.05) ; In the observation group, the rates of patients with long time hospitalization ( ≥30 days), received invasive procedures, and associated with underlying diseases were much higher than the control group( all P ＜ 0.05). ConclusionMultiple risk factors could lead to the occurrence of pulmonary fibrosis patients with nosocomial pulmonary fungal infection,and the positive and effective preventions and standard treatment should be taken.

Primary central nervous system lymphoma (PCNSL) is a rare type of extranodal lymphoma, and its incidence rate is increasing nowadays. Chemotherapy is the main means for treatment of PCNSL and the efficacy of high-dose methotrexate (HD-MTX) has been confirmed among those chemotherapeutics. Treatments of HD-MTX combined with other drugs have been studied extensively. Progress of HD-MTX and other drugs for PCNSL are reviewed in this article.

Trauma is one of the main reasons for the death and disability in children.Ultrasonic tech-nology has been applied in the early assessment and diagnosis of trauma.it is quick,effective,non-invasive, fast imaging,mobile and suitable for different patients and different parts of the body.It has been used to as-sess the organs in patients with severe trauma widely.

The paper elaborates the utilization status of the graphic reports system in hospitals, proposes that ASP .NET technology should be applied to realize the web-based hospital integrated query system for graphic reports, analyzes the advantages of applying ASP .NET technology and introduces the concrete realization of the integrated query system.This system solves the problem that graphic reports are unable to be queried simultaneously, resulting from differences between various internal reporting systems in hospitals.

Scutellarin (SC),a botanical extract,possesses a variety of suppressing free radical generation,anti-inflammatory,cardioprotection and anti-virus activity.Recently,many studies show that SC has inhibitory effects on the growth of many tumors and is a kind of potential anti-tumor drug.Its anti-tumor mechanisms mainly include inducing apoptosis,arresting cell cycle,enhancing the adhesion between cells,inhibiting tumor invasion,reversing multidrug resistance,anti-angiogenesis and so on.

Objective To investigate the expression of proliferating cell nuclear antigen (Ki67) in hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) tissue and its correlation with clinicopathological parameters of HBV related HCC. Methods HBV-related HCC patients (n=134) were divided according to Ki67 index (the percentage of Ki67-posi?tive cells) into Ki67 index<10%group (negative group, n=30) and Ki67 index≥10%group(positive group, n=104). The cor?relation of Ki67 index with age, gender, glypican 3 (GPC3), histological grade, BCLC (Barcelona Clinic liver cancer) staging, portal involvement, AFP (AFP), liver function related child-pugh classification data were calculated in both groups. Ki 67 in?dex is set according to the interval score to assess the relationship between Ki67 score and BCLC classification. Results (1) SP staining showed, Ki67 present a trend of increase from normal liver tissue to well-differentiated to medium differentiat?ed tissue to poorly differentiated tissues intensity. (2) In positive group, Ki67 index was correlated with BCLC staging, portal metastasis, histological grade, GPC3 and AFP (P<0.05);By contrast, in negative group, Ki67 index was not correlated with any clinical parameter (P>0.05). (3) Ki67 score increases with the progress of BCLC classification. Conclusion In Ki67 positive group, Ki67 index combined with GPC3, histological grade, BCLC staging, portal involvement, AFP and liver func?tion child-pugh classification can assess the severity of the patients with HCC, which is expected to become an important in?dicator for the HBV-related HCC early diagnosis.

To discuss the academic features of Ding-Ganren’s medical records and to provide the references for learning and applying the theories in the book. With bibliography research method, the academic features of Ding-Ganren’s medical records were investigated in academic thoughts, medication characteristic and clinic experience, etc. The academic features of Ding-Ganren’s medical records were summarized into 4 pointes, which are ①good at classical prescription and determination of treatment based in pathogenesis obtained through differentiation of symptoms and signs of typhus and complicated diseases. ②Focusing on six meridians and proposing the combination of cold and warm treatment. ③Mild treatment and claiming gentle application of the medicine. ④Determination of treatment based in pathogenesis obtained through differentiation of symptoms and signs of scarlet fever and emphasizing to distinguish Qi from Ying. Ding-Ganren YiAn has high academic value in research and clinic application and worth further study.

Objective To observe the effect of high flux hemodialysis (HFHD) combined with artificial kidney on fibroblast growth factor-23 (FGF-23) in patients with maintenance hemodialysis (MHD). Methods Eighty cases who regularly carried out long-term HFHD in nephrology blood purification center of NO.85 Hospital of PLA were enrolled. All the patients firstly received HFHD alone for 1 month, and then according to random principle, they could receive HFHD followed by hemoperfusion (HP) for treatment (HFHD+HP group) or HP followed by HFHD for treatment (HP+HFHD group). These two types of treatment were respectively carried out for 3 months, and then exchanged to proceed the procedure, the interval of exchange being 1 month (in this month, the two groups of patients all underwent simple HFHD treatment). The therapeutic course was 8 months including 2 cycles. The serum samples were taken from patients undergoing simple HFHD before and after the first month of blood purification, and patients in HFHD+HP group and HP+HFHD group before and after the last month for determination of serum creatinine (SCr), calcium, phosphorus, parathyroid hormone (iPTH), FGF-23 levels. Results The SCr level in HFHD + HP group before hemodialysis was significantly lower than that in simple HFHD group (μmol/L:773.45±212.23 vs. 803.27±192.47, P<0.05), there were no significant differences in blood calcium and phosphorus before hemodialysis between HFHD+HP group and HP+HFHD group (all P>0.05). After hemodialysis, the serum iPTH, FGF-23 were dropped significantly in HFHD + HP and HP + HFHD groups compared with those in simple HFHD group (P < 0.05 or P < 0.01). After hemodialysis, there were no statistically significant differences in SCr and calcium levels between the above two groups (both P>0.05). But the levels of serum phosphorus, iPTH, and FGF-23 in HFHD+HP group were significantly lower than those of HP+HFHD group [serum phosphorus (mmol/L):1.47±0.22 vs. 1.60±0.23, iPTH (μg/L):490.12±145.23 vs. 516.34±165.75, FGF-23 (μg/L): 802.11±92.58 vs. 822.39±107.23, P < 0.05 or P < 0.01]. Conclusions In the aspect of elimination of large and medium sized molecules, the effect of combined artificial kidney is much better than that of simple HFHD. The rates of toxin elimination in different types of combined artificial kidney treatment are different, and the HFHD+HP type has greater effect than HP+HFHD type on elimination of toxins with large or medium sized molecules such as iPTH, FGF-23, etc.
