Objective To discuss the clinical effect of urinary kallikrein in the treatment of progressive cerebral infarction and its influence on hs -CRP.Methods 92 patients with progressive cerebral infarction were ran-domly divided into the observation group(n =46)and the control group(n =46)according to the digital table.The control group was treated with conventional therapy,the observation group was treated with urinary kallikrein based on the control group.The clinical effects and the influence on hs -CRP were compared between the two groups.Results The explicit efficiency and the effective rate of the observation group were 71.7% and 89.1%,which were significant-ly higher than 43.5% and 69.6% in the control group(χ2 =7.522 0,5.372 7,P <0.05 or P <0.01).After treat-ment,the hs -CRP levels in the two groups were (11.79 ±3.92)mmol/L and (10.04 ±3.90)mmol/L,which were significantly lower than (13.48 ±3.89)mmol/L and (13.54 ±3.93)mmol/L before the treatment(t =4.287 4, 2.075 5,P <0.05 or P <0.01),and hs -CRP of the observation group was significantly lower than the control group (t =2.146 5,P <0.05).After treatment,NIHSS scores in the two groups were (9.91 ±4.35)points and (6.82 ± 4.32)points,which were significantly lower than (15.39 ±4.34)points and (15.43 ±4.37)points before treatment (t =6.048 6,9.503 2,all P <0.01 ),and NIHSS score of the observation group was significantly better than the control group(t =3.418 5,P <0.01 ).After treatment,the Barthel in the two groups were (53.87 ±18.12)and (68.21 ±18.14),which were significantly higher than (34.35 ±18.08)and (34.42 ±18.11 )before treatment (t =5.172 1,8.943 4,all P <0.01),and Barthel of the observation group was significantly better than the control group(t =3.793 3,P <0.01).There was no obvious adverse reactions and side effects in the treatment.Conclusion Urinary kallikrein can effectively improve the local blood flow perfusion,restore nerve function damage and improve the living ability of the patients in the treatment of progressive cerebral infarction,it has curative effect,and it's safe and reliable,which is worthy of promotion.

Objective To improve the diagnosis and treatment of epidemic cerebrospinal meningitis in children.Methods A retrospective review was performed and a total of 69 cases of children epidemic cerebrospinal meningitis were collected and classified into ordinary and fulminant epidemic cerebrospinal meningitis from 1999 to 2011.Disease prevalent season,age,clinical characteristics,laboratory examination,treatment,prognosis and risk factors were analyzed.Results The mean age(33 male and 36 female) was (6.85 ±5.12)years old,ranging from 56 days to 15 years old.A total of 60 cases began on January to May; 6 cases began on June to October; 3 cases began on November to December.All of the 42 cases of ordinary epidemic meningitis were recovered; 7 cases of fulminant epidemic meningitis(n =27) were dead.All of the patients had fever; 64 cases(92.75％) had Petechiae petechial skin; 36 cases(52.17％) had headache; 49 cases(71.01％) vomited; 65 cases(94.2％) had positive neck resistance; 15 cases(21.74％) had convulsion; 35 cases(50.72％) had drowsiness or coma; 32 cases (46.38％) had positive pathological signs and 24 cases (34.78％) had low blood pressure or shock.Blood tests revealed that 63.77％ of the patients leukocytes raised and 8.70％ of the patients reduced; 42.03％ of the patients platelet reduced; 55.07％ of the patients had electrolyte disturbance and 89.86％ of the patients had coagulation disorders,among which 46.38％ fibrinogen reduced.The rash printed piece and cerebrospinal fluid smear tests found that Gram-negative bacteria positive rate were 12.5％ and 19.35％ respectively; the positive rate in bacterial culture of cerebrospinal fluid and blood culture were 12.90％ and 7.25％ respectively.Drug sensitive test showed that penicillin and ceftriaxone were sensitive to bacteria.The differences of age,leukocyte and platelet counts,fibrinogen and altered mental status between ordinary and fluminant epidemic meningitis were significant (P ＜ 0.05).Conclusion The prevalent season is from January to May and the prevalent age is less than 5 years for children with epidemic cerebrospinal meningitis.Ceftriaxone or penicillin should be the preferred choice;age,lower leukocyte and platelet counts,lower fibrinogen and altered mental status should be used to predict the severity of the disease.

Objective:To observe the effects of acupuncture-moxibustion on symptoms,signs,and Th1/Th2 cytokine,and regulation on Th1/Th2 in patients with perennial allergic rhinitis(PAR) to provide experimental basis for acupuncture treating allergic rhinitis and investigate the mechanism.Methods:Thirty patients with allergic rhinitis were treated with acupuncture-moxibustion,and 30 healthy cases were the control.Clinical symptoms,signs,and nasal mucosa were observed,and contents of IL-4,IFN-γ,and granulocyte-macrophage colony stimulating factor (GM-CSF) in the supernatant of peripheral blood monocyte cultured with PHA by ELISA,before treatment,after one course of treatment,and after two courses of treatment.Results:Before the treatment,the contents of IL-4,and GM-CSF were higher (P＜0.01) and IFN-γ was lower (P＜0.01) in the PAR cases than in the control cases.In the PAR cases,the content of GM-CSF was positive correlation with that of IL-4 (P＜0.01),and negative correlation with IFN-γ (P＜0.01).After the treatment,contents of IL-4 and GM-CSF were lowed (P＜0.01),content of IFN-γ was increased (P＜0.05),and all IL-4,GM-CSF and IFN-γ had no difference compared with those in the control cases.Conclusion:Acupuncture moxibustion could improve the symptoms and signs in PAR patients,enhance the immune function.It may be achieved by regulating the expression of Th1 and Th2,correcting the imbalance of Th1/Th2.

Objective To compare and observe the clinical effects of microscopic evacuation of intraeranial hematoma and small bone flap approach mierosurgical operation in treatment of hypertensive cerebral hemorrhage.Methods From June 2008 to June 2010,116 cases of patients with hypertensive cerebral hemorrhage were classified into two groups with 58 cases in each by random digits table.Group A was treated with microscopic evacuation of intracranial hematoma and group B was treated with small bone flap approach microsurgical operation.The clinical efficacy and neurological impairment Scores were observed and compared between the two groups.Results The total effective rate in group A[87.9%(51/58)]was significantly higher than that in group B[72.4%(42,58)](P<0.05).After treatment 14 d and 28 d,the neurological impairment scores in group A were (22.1±6.2).(12.6±3.3)scores and in group B were (23.5±6.7),(18.6±5.1)scores.Compared with pre-treatment[group A:(41.9±8.1)scores;group B (41.7±7.9)scores],after treatment l4 d and 28 d,the neurological impairment scores in two groups were significantly decreased(P<0.05).Moreover,After treatment28 d,the neurological impairment scores in group A were significantly lower than those in group B(P<0.05).Conclusion Both microscopic evacuation of intracranial hematoma and small bone flap approach microsurgical operation are effective methods in hypertensive cerebral hemorrhage,but microscopic evacuation of intracranial hematoma can enhance the effect and improve the neurological function.

To analyze the reasons of injuries during surgical practices and explore the hazards and the corresponding preventive measures. The surgical interns don't receive enough training of injury prevention. They don't pay enough attention to the occupational prevention and are not skilled in operation, which causes high rate of sharp edged instrument injuries. Therefore, a perfect plan of education, training and treatment must be made to reduce the occupational injuries and blood sourced diseases.

Objective To investigate the influence of CD4+CD25+ regulatory T cells (Tregs) on the disease progression in MRL/lps mice. Methods Tregs were separated by using magnetic beads from splenic cells of MRL/lps mice and BALB/c mice, and concentrated. Twenty-four MRLAps mice were equally divided into 3 groups, test group 1 injected with Tregs from MRL/lps mice, test group 2 injected with Tregs from BALB/c mice, and control group injected with physiological sodium chloride solution. Three weeks later, the levels of urine protein as well as serum anti-dsDNA antibody were determined; subsequently, the mice were sacrificed followed by histopathological and immunopathological examination of renal tissue. Results A significant decline was observed in the test group 1 compared with the test group 2 and control group in the urine protein score (10.63 ± 4.17 vs. 20.00 ± 5.35 and 18.75 ± 8.34, both P < 0.05), serum anti-dsDNA antibody level (5.36 ± 2.40 pg/ml vs. 9.57 ± 1.97 pg/ml and 10.75 ± 3.98 pg/ml, both P < 0.05), glomerular sclerosis index [(32.00 ± 12.09)% vs. (45.50 ± 13.68)% and (47.50 ± 10.78)%, both P< 0.05], and immunofluorescence intensity of IgG immune complex in renal tissue (1.88 ± 0.99 vs. 2.88 ± 0.64 and 2.75 ± 0.71, both P< 0.05). No significant difference was noted in renal tubule interstitial impairment index between the 3 groups (4.63 ± 1.92, 6.00 ± 1.07 and 5.75 ± 1.28, all P> 0.05). There was no statistical difference between the test group 2 and control group in terms of any of the above parameters (all P > 0.05). Conclusions Injection of Tregs from homologous mice could significantly down-regulate proteinuria degree, serum anti-dsDNA antibody level, glomerular sclerosis index and IgG immune complex level in renal tissue, and thereby decelerate the progression of renal impairment in MRL/lps mice.

Objective To evaluate the imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza.Methods CT and MRI brain imaging data of three children acute necrotizing encephalopathy caused by A H1N1 influenza virus and proved by clinical and laboratory investigation were analyzed.All the three children got CT and MRI scan because of coma while in hospital.Results All cases represented multifocal damage,and some were symmetrical.Bilateral thalamencephalons were involved in the all cases.Bilateral grey and white matters of frontal lobe,temporal lobe,parietal lobe and occipital lobe,and hippocampi,putamina,external capsule,brain stem,bilateral cerebellum,could be seen multifocal damage,and some were symmetrical.All the cases showed brain swelling in varying degrees.These region presented low density in CT,hypointensity on T1 weighted series and hyperintensity on T2 weighted series and FLAIR series in MRI.Conclusion The imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza represented multifocal and symmetrical damage and brain swelling.It may be characteristic that bilateral thalamencephaloas were involved.The patient was serious,and fatality rate was high.So we should pay much attention to acute necrotizing encephalopathy caused by children A H1 N1 influenza.

Objective To investigate the clinical effect of anterior internal fixation plus vacuum sealing drainage in the treatment of ulnar and radial fractures of Gustilo type Ⅲ.Methods Twenty-eight patients with open ulnar and radial fracture of Gustilo type Ⅲ were managed from April 2007 to March 2014,and were divided into four groups(n =4).Group A were managed with external fixator and conventional changing dressings.Group B were managed with internal fixation and vacuum sealing drainage.Group C were managed with external fixator and vacuum sealing drainage.Group D were managed with internal fixation and conventional changing dressings.Result Twenty-eight cases were adopted telephone follow-up for 6 to 27 months.The soft tissue recovery time of each group respectively was (20.5 ± 2.37) days,(14.7 ±2.16) days,(15.6 ±2.17) days and(19.7 ±2.18) days.The hospital stay of each group respectively was (9.7 ± 2.54) weeks,(4.7 ± 1.46) weeks,(5.2 ± 2.34) weeks and 8.6 ± 2.16) weeks.The fracture healing time of each group respectively was (19.6 ± 2.74) weeks,(13.1±1.84) weeks,(18.1 ±2.54) weeks and (14.7 ± 1.74) weeks.There was significant difference of these data between the two groups(P ＜ 0.05).Conclusions Anterior internal fixation plus vacuum sealing drainage is a better way to treat ulnar and radial fractures of Gustilo type Ⅲ.The technique has short period,less complications,less painful and less expense.

The contents of cholesterol in a number of vegetable oils were determined by saponification-gas chromatography ( FID) . There was quite a large possibility that cholesterol peak was seriously interfered by saponification-gas chromatography ( FID) , so it was difficult to set a cholesterol content value to differentiate vegetable oil from waste oil. Solid phase extraction ( SPE) sample pretreatment was chosen and the process conditions were optimized. The optimal conditions were as follows:0. 25 g of oil samples, 20 mL of 0. 6%ethyl ether-hexane ( V/V) as eluent ( get rid of fatty acid glycerides) and 20 mL of 15% ethyl ether-hexane ( V/V) as eluent ( obtain cholesterol) . An obvious cholesterol-content-difference between vegetable oils and waste oils was found by SPE-GC. The detected cholesterol contents in 84 vegetable oil samples were all less than 50 μg/g and the contents of 11 waste oil samples among the 13 waste oils were greater than 50 μg/g. Therefore, cholesterol content in vegetable oil of more than 50 μg/g could be determined as suspected waste oil, not vice versa by SPE-GC. The correlation coefficient R2 was 0. 9999 in 0-760 mg/L concentration range, and the detection limit was 6. 0 μg/g. Relative standard deviations at two concentration levels of 17. 7 and 695 mg/L were 1. 6% and 1. 5% respectively. The recovery was 103%.
