Objective:To observe the clinically curative effects of Qingwen Baidu drink(清瘟败毒饮) on epidemic hemorrhagic fever (EHF).Methods:One hundred and eighty cases with EHF who were admitted to hospital within 5 days after onset were randomly divided into two groups.The control group (n=60) was treated with Ribavirin infused intravenously and liquid therapy,and treating complications simultaneously,meanwhile the treated group (n=120) based on the same therapy as control group treated with Qingwen Baidu drink number Ⅰ,Ⅱ or Ⅲtaken orally two times a day according to different course.Results:In treated group all the days of fever,polyuria,recovering platelet to normal,and transforming proteinuria to negative were significantly shorter than those in control group (both P<0.01),otherwise the overphase rates of oliguria and hypotension shock were higher than those in control group too (all P<0.01).The occurance rate of complications in treated group was lower than that in control group(P<0.05).Conclusions:The curative effects adding Qingwen Baidu drink on EHF are significant and worth spreading.

Objective To discuss the selection and clinical efficacy of operative methods for subaxial cervical dislocation without spinal cord injury. Methods A retrospective study was performed on 11 patients with subaxial cervical dislocation without spinal cord injury treated from January 2004 to June 2009. According to Allen' s classification, all patients suffered from retracted flexion injuries, including seven patients with Ⅰ degree dislocation, one with Ⅱ degree dislocation and three with Ⅲ degree dislocation. There were eighth patients with old dislocation and three with fresh dislocation, both of which were simple cervical trauma without other organ injuries. Open reduction, internal fixation and iliac bone graft spinal fusion were performed in seven patients and combined posterior and anterior open reduction,internal fixation and iliac bone graft spinal fusion in four. All the patients were followed up for observation of clinical effect. Results All operations were completed successfully. There were 11 patients at Frankel grade E preoperatively and 11 at grade E postoperatively. X-ray photographs showed that the sequence and curvature of the cervical spine recovered to normal after operation. All patients were followed up for 3-31 months postoperatively, which showed no redislocation or symptoms of spinal cord injury.Conclusion For lower cervical dislocation combined with locked facet, one-stage combined anterior and posterior reduction and internal fixation should be performed. While for those without locked facet, simple anterior reduction and bone graft spinal fusion is needed. Open reduction, internal fixation and bone graft spinal fusion are effective method for treatment of subaxial cervical dislocation without spinal cord injury.

Objective To summarize the experience of tension-free repair for inguinal hernia in the preperitoneal space using modified surgical mesh. Methods From Dec 2008 to May 2010, 134 cases with 138 reducible primary inguinal hernia were randomly divided into two groups. Sixty-seven patients (70 hernias) in the study group underwent tension-free repair in the preperitoneal space by modified surgical mesh, while the control group (67 cases, 68 hernias) underwent Rutkow's herniorrhaphy by surgical mesh.Results Postoperatively 127 cases (95%) were followed up from 2 to 18 months with an average of 9. 2months[64 cases of the test group were followed up with an average of(9 ±4) months, 63 cases of the control group followed up with an average of (9 ± 5 ) months]. There was no recurrence. No significant differences were found between the two groups in the operation time (P = 0. 697), blood loss (P = 0. 318 ),hospital stay (P = 0. 116) and total postoperative complications (P = 0. 080). The visual analogue scale of the study group was lower than the scale of the control group ( P = 0. 048 ). Conclusions Modified surgical mesh is more comfortable in the treatment of inguinal hernia with tension-free repair in the preperitoneal space with a comparative result to Rutkow's herniorrhaphy by surgical mesh.

Objective To investigate the effect of fish oil parenteral supplementation on monocyte function in gastrointestinal cancer patients.Methods Sixty-four gastrointestinal cancer volunteers were equally randomized into study group and control group.Both groups received conventional lipid emulsion,and the study group was added with fish oil parenteral supplementation for 5 days.Blood samples were collected on the 1st,3rd,and 6th post-operative days to detect the interleukin (IL)-1β,IL-10,IL-6,tumor necrosis factor-α,and human leukocyte antigen-DR.Results After 5 days of continuous management,the IL-1β,IL-6,and tumor necrosis factor-o levels in the study group became significantly lower than those in the control group [(1 818 ± 213)pg/Lvs (2292 ±289)pg/L,P=0.027; (415 ±71)pg/Lvs (791±163)pg/L,P=0.001; (2 194± 350) pg/L vs (2 509 ± 507)pg/L,P =0.036,respectively),whereas the level of IL-10 by mononuclear leukocytes in two groups showed no significant difference.The expression of human leukocyte antigen-DR was significantly increased in both groups,but was significantly higher in the study group than in the control group [(76.6±15.2)％ vs (62.3±16.8)％,P=0.029].Conclusion Fish oil helps improve postoperative monocyte function in patients with gastrointestinal tumor.

ObjectiveTo investigate the protective effect and mechanism of monosialotetrahexosyl gangliosides ( GM-1 ) on neurons after spinal cord injury (SCI) in rats by observing the effect of GM1 on the expression and motor function of microtubule-associated protein 2 (MAP-2) and Choline acetyltransterase (ChAT). MethodsSixty-six adult female Wistar rats (weighing 260-300 g) were enrolled in the study and six were selected randomly as the normal control group. The rest were divided into GM1 group (group A, n =30) and normal saline control group (group B, n =30) after acute contusion injury was made at T10 level according to the improved Allen's method. At days 1,3, 7, 14 and 28 after operation, the neurological function of the low extremities was assessed with the improved Tarlov scale. Then,the rats were sacrificed to obtain the spinal cord tissues. There were six rats in each group at different time points. The expressions of MAP-2 and ChAT were detected with immunohistochemistry after SCI in rats. ResultsThe improved Tarlov scale in the Group A was higher than that in the Group B after SCI since the 7th day after operation, with statistical difference at day 7, 14 and 28 after operation ( P ＜0. 05). The expressions of MAP-2 and ChAT in the Group A were higher than that in the Group B after SCI ( P ＜ 0.05 ). ConclusionsThe neurological function recovery of the low extremities has some correlations with the expressions of MAP-2 and ChAT after SCI in the rats. GM-1 can protect the neurons by promoting the expressions of MAP-2 and ChAT after SCI.

Objective To summarize the efficacy and the feasibility of 125I seed implantation for recurrence cervical lymph node of head and neck tumor after radiotherapy or radiotherapy plus neck dissection. Methods Thirty-six patients with the recurrence cervical lymphnode of head and neck tumor after radiotherapy (17 patients) or radiotherapy plus neck dissection (19 patients) were treated with 125I seed implantation guided by ultrasound or CT under local anesthesia. The median number of seeds was 27( range from 3 to 78 ). Postoperative quality evaluation were routinely obtained for all patients. The actuarial D90 ranged from 90-160 Gy (median, 130 Gy). Results The follow-up rate was 100%. The number of the patients who were followed up over 1-and 2-year were 11 and 3. The overall response rate was 81%. The 1-and 2-year over local control rates, over survival rates were 69% and 35%, 50% and 22%, respectively.The 1-and 2-year local control rates in patients with recurrence node after radiotherapy plus neck dissection were 72% and 54%, while those were 67% and 50% in patients with recurrence node after radiotherapy,respectively (χ2=00,P=0.965). The 1-and 2-year survival rates in two groups were 48%, 13% , and 51%, 39%, respectively (χ2=0.17, P=0.676). Conclusions 125I seed implantation is a safe,minimal invasive with low morbidity and high efficacy salvage treatment method for cervical lymph node recurrence of head and neck tumor after radiotherapy with or without neck dissection.

Objective: Based on scores by number of vessels diseased and age (NVDA), the minimum lumen area (MLA) of left anterior descending (LAD) proximal or middle intermediate lesions were examined by intravascular ultrasound (IVUS) to analyze the clinical characteristics, to ifnd the factors affecting lumen area and to establish a scoring system for predicting MLA in relevant patients.
Methods: A total of 90 patients were enrolled including 58 male and 32 female with the age of (41-77) years. The demographic information, medical history and laboratory results were studied by simple linear regression analysis to screen relevant factors affecting MLA; multi regression analysis was conducted to establish a regression equation for predicting MLA and to calculate the risk factor coefifcient for obtaining relevant scoring system.
Results: NVDA score≤4 was deifned as negative result with speculated MLA≥3.0mm2, while NVDA score>4 was deifned as positive result with speculated MLA<3.0mm2. The sensitivity, speciifcity and negative predictive value of NVDA scoring system for predicting MLA were 83.35%, 75% and 90% respectively.
Conclusion: NVDA scoring system had the better accuracy, sensitivity and speciifcity for predicting MLA in coronary artery intermediate lesions, it had certain value for guiding coronary interventional therapy in relevant patients.

Objective To investigate the safety and short-term outcome of rotational atherectomy followed by drug-eluting stenting in heavily calcified coronary long lesions. Methods From Jan 1, 2011 to May 31, 2016, 109 cases with 114 heavily calcified coronary lesions which were treated with rotational atherectomy followed by drug-eluting stenting in Peking University People's Hospital were included. They were divided into diffuse lesion group ( lesion ≥25 mm, 68 cases, 72 lesions ) and focal lesion group (lesion ﹤25 mm,41 cases, 42 lesions). All patients were followed up in hospital. Procedure parameters, procedural complications ( dissection, perforation, slow flow/no flow and procedural related myocardial infarction),procedural success and major adverse cardiovascular events (cardiac death, non-fatal myocardial infarction and stent thrombosis) were analyzed. Results The procedural success rate was 98. 5%(67/68) in diffuse lesion group and 100% ( 41/41 ) in focal lesion group ( P=0. 453 ) . Complication rates did not differ between the two groups (41. 2% and 34. 1%, P=0. 673). Major adverse cardiovascular events rates were 41. 2% and 31. 7%, P =0. 484. Conclusions Treating coronary lesions ≥25 mm in length with rotational atherectomy followed by drug-eluting stenting does not impact the short-term outcome when treating carefully and correctly . Procedural success rate and in-hospital outcome is satisfactory.
