Of the 250 cases of blunt abdominal trauma,15 cases of pancreatic lesions were complicatedwhich include 3 cases lacerated on the head of pan-creas, 5 on the body, 6 on the tail and one con-tused. The pancreatic bed drainage was performedfor one case, repair for 8 cases and pancreatic tailresection for 6 cases, In author's experiences, theroutinely inspecting the pancreas was carried outintra operatively, with blunt epigastric trauma, es-pecially the light red hemotoliquid was found bypericentesis. Operative method was classified frompancreatic bed drainage, repair and resection in ac-cordance with severity of the trauma, For prevent-ing the pancreatic juice fistula, the main pancreaticduct must try its best to be ligated. If the traumais on the head, a common bile duct and duodenumdecompression must be done.

Objective To prepare an active anti-tumor component, compound K (C-K), from saponins in leaves of Panax notoginseng (SLPN) using immobilized β-glucanase. Methods Two entrapments, alginate gel-1 (Alg 1) and alginate gel-2 (Alg 2), were evaluated for their ability to immobilize β-glucanase. The amount and purity of C-K obtained from the transformation process were analyzed by HPLC, and the immobilizing parameters were optimized. Results β-Glucanase can be immobilized and reused with either of the entrapment. However, using AIg 1 resulted in higher enzyme activity than Alg 2. The optimal concentration of the immobilized enzyme was 10%; The optimal crosslinking time was 4-6 h; and the optimal concentration of the crosslinking agent was 6%-7%. Conclusion Immobilized β-glucanase shows sustained enzyme activity, good ethanol tolerance, and was reusable for the preparation of C-K from SLPN.

Objective To explore the expression and significance of vascular endothelial growth factor (VEGF) and transforming growth factor β1 (TGF-β1) in hepatic fibrosis.Methods Fifty-six cases of patients with hepatic fibrosis were selected as observation group and 50 healthy persons as control group.Immunohistochemistry were performed to detect VEGF and TGF-β1 in two groups.Results Serum VEGF and TGF-β1 in observation group were significantly higher than those in control group(VEGF:(110.87 ±32.64) μg/L vs (15.98 ±6.75) μg/L,t =20.166,P ＜0.001;TGF-β1:(15.08 ±4.27) ng/L vs (7.17 ±2.86) ng/L,t =11.066,P ＜ 0.001) ;There were significant differences on VEGF and TGF-β1 level among S1,S2,S3 and S4 subgroups(VEGF:(84.25 ±16.86) μg/L vs (101.87 ±36.70) μg/L vs (118.04 ±40.75)μg/L vs (134.65 ± 45.73) μg/L,F =15.689,P =0.015 ; TGF-β1:(10.87 ± 2.64) ng/L vs (13.06 ± 2.74)ng/L vs (17.87 ± 3.28) ng/L vs (22.76 ± 4.75) ng/L,F =12.438,P =0.026).VEGF had positive correlation with TGF-β1 (r =0.532,P =0.013).Conclusion VEGF and TGF-β1 level have close relationship with the occurrence and development of hepatic fibrosis.Combined detection of VEGF and TGF-β1 can be serum index for diagnosis and evaluation disease condition.

Objective To evaluate preliminary effect of In-Space percataneous interspinous spacer in the treatment of lumbar instability.Methods Data of 18 patients who had undergone interspinous spacer implant for lumbar instability from May 2009 to June 2011 were retrospectively analyzed.There were 10 males and 8 female,aged from 39 to 58 years.All patients suffered from varying degrees of lower back pain induced by lumbar hyperextension,as well as radiating and segmental pain of unilateral lower limb.The visual analogue scale (VAS) and Oswestry disability index (ODI) were used to evaluate clinical outcomes.The pre-and postoperative interspinous distance,trailing edge height of intervertebral space,foraminal width,foraminal height,segmental lordotic angle and lumbar range of motion were tested and compared.Results All patients were followed up for 18 to 36 months.The VAS score improved from preoperative 7.9±2.1 to 3.1±1.3 at 6 months postoperatively and 1.5±0.8 at final follow-up.The ODI improved from preoperative 82.1％±13.1％ to 54.7％±14.8％ at 6 months postoperatively and 10.1％±2.5％ at final follow-up.The postoperative interspinous distance,trailing edge height of intervertebral space,foraminal height,foraminal width,segmental lordotic angle and lumbar range of motion were 9.29±1.43 mm,11.28±0.85 mm,21.27±1.01 mm,10.83±0.73 mm,7.62°±0.74° and 6.34°±0.81°,respectively.Wound healed smoothly in all patients,and there were no complications such as spinous process fracture,spinal cord injury,cerebrospinal fluid leakage,device displacement and device dislocation.Conclusion It is easy and safe to use In-Space percataneousinterspinous spacer in the treatment of lumbar instability,and the preliminary effect is satisfactory.

Objective To discuss the clinical value of intravascular ultrasound (IVUS) in treatinginternal carotid arteries occlusion.Methods The patient was diagnosed with internal carotid artery occlusionthat was confirmed by CTA.Cerebral perfusion imaging showed that low perfusion area was consistent withischemic symptoms.Guided by IVUS,percutaneous transluminal angioplasty (PTA) was performed.By usingmicro-catheter coaxial technology,the micro guide wire was inserted in the carotid artery until it passedthrough the obstructed segment;After IVUS examination proved that the micro guide wire was in the truelumen of carotid artery,angiography through micro-catheter was carried out to confirm that the distal arterywas unobstructed;after adjusting the device position the embolism protector was placed.The plaque andlumen condition were assessed with IVUS,which was reevaluated after pre-expansion of balloon.After normaldirection blood flow was regained,the plaque stability was assessed with IVUS virtual organization sequence.Simple balloon dilatation therapy was adopted as the fibrous cap of plaque was in stable condition and thelumen stenosis rate was ＜40％.Results After balloon dilatation,the obstructed artery was reopened and theblood flow regained normal direction.IVUS examination showed that during the whole operation process thefibrous cap of plaque at the narrowed segment remained in stable condition,the lumen stenosis rate was ＜40％.Cerebral perfusion imaging revealed that after the treatment the low perfusion state was markedlyimproved.Conclusion IVUS plays an important guiding role in performing PTA for internal carotid arteryocclusion.This technique can increase the success rate of vascular recanalization and reduce the incidence ofcomplications.

Objective To observe the characteristics of respiratory airflow in healthy adults and stable chronic obstructive pulmonary disease (COPD) patients by analysis of analyzing tidal breathing flow-volume curves (TBFV). Methods Fifteen stable moderate COPD patients (COPD group) and 15 healthy cases without smoking(healthy control group)were enrolled into the study. No bronchodilators were used in patients of COPD group 8 h before test. Pulmonary function test and TBFV in seated position were measured, and the pressure of oral cavity was monitored concomitantly. Results The levels of percentage of vital capacity (VC%), percentage of forced expiratory volume in the first second (FEV 1)/forced vital capacity (FVC) and percentage of maximum mid-expiratory flow (MMEF%) in COPD group were significantly lower than those in healthy control group (P<0.01). The parameters of TBFV showed that the fraction of exhaled volume to achieve PTEF to VTE (VPTEF/VTE) and the fraction of exhaled time to achieve PTEF to TE (TPTEF/TE) in COPD group were 0.18 ± 0.08 and 0.20 ± 0.08, which were lower than those in healthy control group: 0.27 ± 0.04 and 0.29 ± 0.06, and there were significant differences (P<0.01). The level of peak tidal expiratory flow (PTEF) and peak tidal inspiratory flow (PTIF) in two groups had no significant differences (P>0.05). The levels of tidal expiratory flow at 50%of the remaining tidal volume/PTEF (TEF50/PTEF) and tidal expiratory flow at 25%of the remaining tidal volume/PTEF (TEF25/PTEF) in healthy control group were significantly higher than those in COPD group:0.54 ± 0.13 vs. 0.40 ± 0.12, 0.28 ± 0.13 vs. 0.20 ± 0.06, P<0.01 or<0.05. No differences were found in peak inspiratory pressure (PI max) and peak expiratory pressure (PE max) between two groups. Conclusions The degree of airflow limitation and the effect of bronchodilator in critical patients could be evaluated by analysis of TBFV parameters. The measurement of TBFV is simple and don′t need special technique. It is worth of promoting.

Objective To study the relationship of three-dimensional power Doppler ultrasonographic parameters and endocrine profile in different symptoms of patients with polycystic ovary syndrome(PCOS).Methods One hundred and forty nine women with PCOS were divided into two groups,which included obese PCOS(OB-PCOS) group and non-obese PCOS (NOB-PCOS) group.The ultrasonic parameters such as follicle number,ovarian average diameter,ovarian volume,stromal volume,follicle volume,vascularization index(Ⅵ),flow index(FI),vascularization flow index(VFI) were measured and compared.Serum levels of luteinizing hormone (LH),follicle stimulating hormone (FSH),progesterone (P),estradiol (E2),testosterone(T),prolactin (PRL),sex hormone binding globulin (SHBG),free androgen index (FAI),fasting plasma glucose (FPG),fasting insulin (FINS),homeostasis model assessment-IR(HOMA-IR) were also measured and compared.The correlation of the ultrasonic parameters and hormonal factors were analyzed.Results The follicle number,ovarian average diameter,ovarian volume,stromal volume,follicle volume,FI and VFI,FINS,HOMA-IR,FAI of OB-PCOS were significantly higher than those of NOB-PCOS (P ＜0.01 or 0.05),the FSH,SHBG were significantly lower than those of NOB-PCOS (P ＜0.05 or 0.01).In OB-PCOS group,the follicle number was significantly associated with FSH(r =0.771,P ＜0.01).The ovarian volume,stromal volume,FI and VFI were significantly associated with HOMA-IR(r =0.412,0.842,0.389,0.415,P ＜0.05 or 0.01),FI was significantly associated with FAI (r =0.812,P ＜0.01).In NOB-PCOS group,the follicle number,ovarian volume were significantly associated with FAI(r =0.472,0.552,P ＜0.05)..Conclusions There are some different characters in ultrasonography and endocrine parameters between obese and non-obese PCOS patients.

Objective To observe the clinical efficacy on the treatment of diabetic gastroparesis of self-designed Xiaopi Formula. Methods Totally 200 cases of DGP were divided into the observation group and the control group with random number table, with 100 cases in each group. Two groups were given the general treatment scheme, such as the subcutaneous injections of insulin or oral hypoglycemic medicine. The patients in the control group were treated with Domperidone orally, one tablet each time, 3 times a day;while the patients in the observation group were treated with self-designed Xiaopi Formula, twice a day, one time for morning and one time for evening. One course lasted for one month, 3 courses in total. Clinical efficacy and the change of gastric emptying rate, glycosylated hemoglobin and hemorrheology in the two groups were observed. Results Total effective rate of observation group (94.0%) was higher than that of the control group (82.0%), with statistical significance (P<0.05). After treatment, blood sugar decreased and gastric emptying rate improved in both groups (P<0.05), and observation group was superior to control group (P<0.05); The control group in terms of improving hemorrheology had no obvious significance (P>0.05); Observation group can obviously improve the indexes of blood rheology, with statistical significance with control group (P<0.05). Conclusion The clinical efficacy of self-designed Xiaopi Formula for the treatment of diabetic gastroparesis is obvious, which can promote gastric emptying rate and decrease HbA1c level, and improve blood rheology.

Objective To explore the non-bacteria pathogens of acute laryngitis in children. Methods The clinical data and sputum sample were collected from 325 patients hospitalized due to acute laryngitis in consecutive 10 years from January 2006 to December 2015 . The multiple non-bacteria pathogens were detected and analyzed with clinical data. Seven types of respiratory viruses were detected by direct immunolfuorescence. Mycoplasma pneumoniae (MP), Chlamydia pneumoniae (CP), and Boca virus (HBoV) were detected by lfuorescence quantitative PCR. The rhinovirus (HRV) and human metapneumovirus (hMPV) were detected by RT-PCR. Venous blood was collected within 24 h after hospitalization and 7-10 d after treatment. The MP antibody of IgG and IgM were detected by ELISA. Results The detection rate of non-bacteria pathogens was 46 . 2%in 325 children with acute laryngitis ( 150/325 ), including 76 cases ( 23 . 4%) of virus and 99 cases ( 30 . 5%) of MP. Virus detection rate in 1-3 year old children was obviously higher than in 0-1 year old children and over 3 years old children (χ2?=?9 . 527 , P=?0 . 009 ). With the increase of age, the detection rate of MP increased gradually (χ2?=?10 . 132 , P=?0 . 006 ). The detection rates of RSV and hBoV were higher in under 3-year-old children. The detection rates of virus in winter and spring were signiifcantly higher than those in summer and autumn (χ2?=?5.064, P=?0.024). The detection rates of MP in winter, spring, summer, and autumn was 13.1%, 25 . 0%, 38 . 2%, and 44 . 9%respectively, and the MP detection rates were increased gradually over seasons (χ2?=?4 . 438 , P=?0 . 035 ). The detection rate of RSV was higher in winter, and hBoV was higher in summer. Conclusion Acute laryngitis mainly occurred in children under 3-years-old children, and the detected non-bacteria pathogens were different among different ages and seasons. Virus was the major pathogens in young children, while MP was more common in older children.
