Objective To analyze testing results and values of blood heterotypic lymphocyte in flu patients.Methods 100 cases of influenza patients and 100 healthy people were collected.The observation group for flu patients and control group of healthy people.Extraction of peripheral blood in patients with microscopic examination observing leukocyte,neutrophil,lymphocyte,intermediate cells,atypical lymphocytes under a microscope,and calculated the percentage in the patients in the two group cells to make analysis and comparison.Ratio in peripheral blood of patients and analysis of specific lymphocytes were also calculated between different ages.Results Peripheral blood lymphocytes in observation group was (11.1 ± 2.6) ％,which was significantly higher than than of the control group [(1.5 ± 0.5) ％].The difference was statistically significant (chi-square =16.9,P ＜ 0.05) ; White blood cells,the ratio of neutrophils,lymphocytes in observation group were obvious differenent compared with the control group(t/chi square are:13.2,11.3 and 12.6,P ＜ 0.05) ;Three ages of influenza patients peripheral blood lymphocytes of the opposite sex ratio has no difference(P ＞ 0.05).Conclusion Detection of peripheral blood lymphocyte heterosexual has great significance to the diagnosis of influenza with simple,convenient and feasible characters.It is worth to be used widely in clinical practice.

Objective To analyze the efficacy and experience of coil embolization in patients with pulmonary arteriovenous malformations(PAMV). Methods Seven patients (2 males and 5 females, age range from 11 to 52 years; mean age 31 years) were admitted including 4 single saccular, 2 multiple saccular, 1 diffuse capillary pulmonary arteriovenous malformations. Results Coil embolization of pulmonary arteries was successful in all 7 patients. The mean arterial oxygen saturation rate increased from 87% to 96% in patients with saccular PAMV. Transient chest pain occurred in a case of diffuse capillary PAMV during the procedure, after undergoing multiple coil embolization, the arterial oxygen saturation rate increased from 79% to 87%. All patients were followed up for 6 months to 5 years, arterial oxygen saturation declined slightly,and mild to moderate tricuspid regurgitation was found by echocardiography only in the patient with diffuse capillary PAMV.Conclusion Coil embolization is an effective and safe method of treatment for saccular PAMV. But it is only a palliative therapy for diffuse capillary PAMV.

Objective To elucidate the efficacy and safety of transcatheter closure of secondary atrial septal defect (ASD) with Amplatzer septal occluder (ASO) in people over 50 years of age. Methods Retrospective comparison of 41 patients (14 males, 27 females) with ASD over 50 years of age ranging from 50 to 75(mean age 55.5?7.6, elder group) was conducted with 132 patients younger than 50 years(control group). After diagnosis of ASDs and evaluation of pulmonary artery systolic pressure and right atrial and ventricular dimensions by transthoracic echocardiography (TTE), all patients underwent transesophageal echocardiography (TEE) for complete assessment of ASD size, margins and anatomic relationship of the defect before closure of ASD. Each case was treated with ASO through the percutaneous transcatheter procedure under fluoroscopy and TTE or TEE. Early follow up(3 months) by echo was taken after the intervention. Results There was no difference of mean defect diameter measured by TEE and the balloon-stretched defect diameter of the ASDs between 2 groups. Pulmonary artery pressures in elder group were higher than those in younger group(P

Objective To study CT and MRI features and classification of brain schistosomiasis granuloma. Methods CT and MRI data of 30 cases of brain schistosomiasis granuloma were reviewed.All cases were proved by the surgery or pathological examination and clinical laboratory test.There were 20 males and 10 females, and their age ranged from 5 to 58 years, mean 29.2 years.Plain and enhanced CT were performed in all patients with GE MAX 640 scanner.Ten patients were examined by plain and enhanced MRI with GE Signa profile 0.2 Tesla open scanner.Results The lesions located in supratentorial region in 27 cases and in infratentorial region in 3cases.The nodules were isodense or slight hyperdense on CT plain scan, iso or hypointense on T_1WI, hyperintense on T_2WI, Slight hyperintense on FLAIR.After the contrast material was injected intravenously, CT and MRI findings were multiple or single enhanced nodules at the cortical or subcortical area.There were four types of imaging features: (1) multiple small nodules in 5 cases (presenting as bright stars in the dark sky); (2) single large nodule in 8 cases; (3) mixed nodules in 14 cases; (4) circle-enhanced nodules in 3 cases.Conclusion The brain schistosomiasis granuloma has typical CT and MRI findings.CT and MRI classification is not only helpful to its diagnosis and differential diagnosis, but also might be useful for the choice of clinical treatment.

Objective To evaluate the value of immature granulocytes count in diagnosing and monitoring the systemic inflam-matory response for patients with systemic inflammatory response syndrome,and to provide a new indicator of systemic inflammato-ry response.Methods 207 patients suspected of systemic inflammatory response syndrome were enrolled.The dynamic changes of immature granulocytes counts and the disease situation were recorded for all subjects.The blood samples were collected in vacuum tubes with EDTA-K2 anticoagulant.Blood cell count and immature granulocytes count were performed in Sysmex XE-2100 hema-tology analyzer.The determination of C-reactive protein and procalcitonin were also completed.The performance of immature granu-locytes in diagnosing systemic inflammatory response syndrome was evaluated by receiver operating characteristic curve analysis. Results The area under the curve of immature granulocyte count (IG #)was 0.78 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 62.2 % and a specificity of 73 % at IG #> 0.1 65.The area under the curve of immature granulo-cyte percent (IG%)was 0.771 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 54.1 % and a specifici-ty of 94.6 % at IG%>2.55 %.The area under the curve of C-reactive protein was 0.71 6 in diagnosing systemic inflammatory re-sponse syndrome,with a sensitivity of 67.6% and a specificity of 75.7 % at C-reactive protein> 64.15 mg/L.The area under the curve of procalcitonin was 0.772 in diagnosing systemic inflammatory response syndrome,with a sensitivity of 75.7 % and a speci-ficity of 70.3 % at procalcitonin> 0.33 mg/L.Conclusion Immature granulocyte count is beneficial for the diagnosis and the as-sessment of prognosis of systemic inflammatory response syndrome.

Objective To assess the clinical efficiency , safety and potential advantages of autologous blood transfusion (ABT) drains compared with the closed-suction/no drainage. Methods Pubmed, Embase, Cochrane Library, CBMdisc, CNKI, VIP and WANGFANG were searched comprehensively. The statistical anal-ysis was conducted by using the Cochrane Collaboration review Manager 5.3.5. Results The pooled data of seventeen RCTs including a total of 1 993 patients showed that the patients in the ABT drainage group might benefit from the low rate of blood transfusion [ 16 . 59% and 37 . 47%, OR: 0 . 28 ( 0 . 14 ~ 0 . 55 ); 13 . 05% and 16.91%, OR: 0.73 (0.47 ~ 1.13), respectively]. The ABT drainage and the closed-suction drainage/no drainage have the similar clinical efficiency and safety length of hospital stay and wound infection on days 3 post-operative haemoglobin. Conclusion This systematic review provides the evidence that the ABT drainage offers a safe and efficient alternative to CS/no drainage with the lowered blood transfusion rate.

Objective To study the expression of aquaporin-4 (AQP-4) in core and marginal region of the contusion brain tissues from patients with severe traffic brain injuries. Methods Thirty patients with severe traffic brain injuries (frontal-temporal brain contusion) admitted into our department from January 2007 to July 2009 were enrolled in the study and divided into three groups according to the period from injury to operation, ie, 0-4 hours (Group A), 5-8 hours (Group B) and 9-12 hours (Group C). The tissue was collected from core and marginal regions of brain contusion in each group. Ten parts of normal brain tissues obtained from the cerebellum to gain good exposure of CPA region tumors were used as control. The expression of AQP-4 in the normal brain tissues and in the tissues from core and marginal region of brain contusion, with GAPDH used as a control. Results The expression of AQP-4 in the marginal region was distinctly higher than that in normal tissues and in the tissues from core region. The AQP-4 expression in the tissues of the core region was lower than that in normal tissues. Conclusions AQP-4 is highly expressed in the tissues from the marginal region early after injury in a time-dependent fashion. Low expression level of AQP-4 in the core region is possibly correlated with early damage of blood brain barrier and peripheral structures.

BACKGROUND:Kidney-tonifying herbs have been reported to promote tendon-bone healing in rabbits after anterior cruciate ligament reconstruction (ACLR). OBJECTIVE:To verify the effects of kidney-tonifying herbs on tendon-bone healing after ACLR. METHODS:Seventy patients with anterior cruciate ligament injury undergoing ACLR were randomly assigned to study group (administration of Liuwei dihuang pil s+celecoxib) and control group (administration of celecoxib alone). Preoperative, postoperative 6-and 12-month assessments of patients by the Lysholm Knee Scoring Scale, International Knee Documentation Committee (IKDC) Subjective Knee Form and MRI imaging were performed. RESULTS AND CONCLUSION:Postoperative Lysholm scores were significantly increased compared with preoperation in the study and control groups (P<0.05), and the scores of sections stair-climbing and instability and total scores of the Lysholm Knee Scoring Scale in the study group were superior to those in the control group (P<0.05). Postoperative IKDC scores were significantly increased compared with pre-operation in the study and control groups (P<0.05), and the scores of section flaccid leg and subjective function and total scores of the IKDC in the study group were superior to the control group (P<0.05). The enlargement rate of middle and proximal parts of grafts was significantly increased in the study group compared with the control group 6 months postoperatively (P<0.05), and the enlargement rate of middle and distal parts of grafts was significantly increased in the study group compared with the control group 12 months postoperatively (P<0.05). The tibial and femoral tunnel enlargement was observed in both groups at 6 and 12 months postoperatively (P<0.05). The enlargement rate of the tibial tunnel was significantly decreased in the study group compared with in the control group (P<0.05). The signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly higher than that in the control group 6 months postoperatively (P<0.01). In contrast, the signal-noise ratio of the femoral end and middle part of grafts in the study group was significantly lower than that in the control group 12 months postoperatively (P<0.05). Our results indicate that kidney-tonifying herbs can improve the tendon-bone healing after ACLR.

BACKGROUND:Absorbable colagen membrane can be theoreticaly applied to secondary alveolar bone grafting in alveolar cleft surgery, which can improve the bone preservation and slow bone resorption. However, there is stil no unified conclusion.
OBJECTIVE:To assess the efficacy and safety of absorbable colagen membrane for secondary alveolar bone grafting viaa systematic review.
METHODS:MEDLINE, EMBASE, CBM and CAJD were searched for eligible articles addressing clinical randomized controled or controled trials of absorbable colagen membrane for secondary alveolar bone grafting. Test group received bone grafting with absorbable colagen membrane and control group only received bone grafting. Meta-analysis on the clinical success rate of bone grafting and incidence of complications in the recipient region was delivered with Revman 5.3.
RESULTS AND CONCLUSION:Five clinical trials, involving 416 cleft sites and 387 participants, were included. Two had high risk of bias and the rest had unclear risk of bias. If “the height of new bone is≥ 50% of alveolar height” was adopted as clinical success, the clinical success rate of the test group was significantly higher than that of the control group (P=0.002, relative risk value=1.33, 95% confidence interval [1.11, 1.60]). If “the height of new bone is≥ 75% of alveolar height” was chosen as clinical success, the clinical success rate of the test group was higher than that of the control group, but there was no significant difference between the two groups (P=0.06, relative risk value=1.40, 95% confidence interval [0.99, 1.99]). For safety, the use of absorbable colagen membrane could not increase the complications incidence (P=0.35, relative risk value=0.66, 95% confidence interval [0.28, 1.58]). So, the use of absorbable colagen membrane is safe to improve the clinical success rate of secondary alveolar bone grafting in alveolar cleft surgery. More randomized controled trials should be considered to reinforce the conclusion.

BACKGROUND:There are numerous clinical studies on comparing absorbable internal fixation system and titanium metal internal fixation system in maxilofacial fractures; however, the systematic reviews and Meta-analysis in this field are rare. OBJECTIVE:To compare the clinical effect of absorbable internal fixation system and titanium internal fixation system in maxilofacial fractures through systematic review and Meta-analysis. MATERIALS AND METHODS:The randomized controled trials and controled clinical trials regarding the application of absorbable internal fixation system and titanium internal fixation system in maxilofacial fractures were electronicaly retrieved from Medline, Embase, the Cochrane Central Register of Controled Trials, China Biology Medicine disc, and China Academic Journal Network Publishing Database using the keywords. Meta-analysis was conducted using Revman 5.3 software. RESULTS AND CONCLUSION:Thirteen clinical studies were included, and totaly 1 718 patients were involved. The Meta-analysis results showed that the removal rate of implants in the absorbable internal fixation system group was significantly lower than that in the titanium internal fixation group (P=0.000 2); there were no significant differences in the healing rate of fracture I stage, the incidence of insufficient fixation in fracture site and the incidence of long-term complications between these two groups. These results demonstrate that the efficiency and safety of absorbable internal fixation system in maxillofacial fracture is satisfactory, and can reduce the proportion of secondary surgical removal of the implant. More randomized controlled trials should be conducted to confirm this conclusion.
