Objective To compare the effects and complications of lumboperitoneal shunt ( LP ) and ventriculoperitoneal shunt ( VP ) in the treatment of post?traumatic hydrocephalus. Methods Eighty patients with post?traumatic hydrocephalus treated in the neurosurgery department of Zhangjiagang Hospital of Traditional Chinese Medicine from March 2014 to March 2010 were retrospectively analyzed. The patients were randomly divided into two groups,40 patients treated with LP were assigned into the LP group and 40 patients undergone VP treatment were seen as the VP group. All patients were followed up for 1 year to investigate and compare the symptom improvement rate,neurological deficit score and the incidence of complication of the two groups. Results The total effective rate of hydrocephalus disappearance in the LP group was 41. 50% ( 37/40) and 87. 50%( 35/40) in the VP group. The difference between the two groups was not statistically significant (χ2=0. 556,P=0. 456);the neurological deficit scores before treatment in the LP group and VP group were (28. 35±8. 64) points and (29. 13±7. 98) points,there was no significant difference between the two groups (t=0. 419,P=0. 676) . The difference in the scores of neurological deficit after treatment in the LP and VP group was not statistically significant ( (19. 32±5. 34) points vs. (21. 62±4. 86) points,t=1. 480,P=0. 143),the average scores of neurological deficits in the two groups were significantly better than those before treatment ( t=5. 623, 5. 084,P<0. 001 ) . There was no significant difference in the average score of improvement of urinary incontinence between the two groups before and after treatment ( t=0. 376,1. 265,P>0. 05) ,the average score of urinary incontinence improvement after treatment in both groups were better than those before treatment ( t=4. 891,5. 370,P<0. 001) . In the LP group,the incidence of bleeding,infection,shunt related complications and shunt abnormality were all 2. 50% ( 1/40 ) , the overall complication rate was 10. 00%, the incidence of bleeding,infection,shunt related complications and shunt abnormality in the VP group were 7. 50% (3/40), 10% ( 4/40 ) , 5% ( 2/40 ) 10%, ( 4/40 ) , the overall complication rate was 32. 50%, there was significant difference between the two groups (χ2=6. 050,P=0. 014) . Conclusion LP and VP have significant curative effect on the treatment of post?traumatic hydrocephalus,but the overall incidence of LP complication after 1 year is significantly lower than that of VP,and is worth popularizing widely in clinical practice

OBJECTIVETo explore the clinical application of mandibular-driven simultaneous maxillo-mandihular distraction to correct hemifacial microsomia with rapid prototyping technology.

METHODSThe patient' s skull resin model was manufactured with rapid prototyping technology. The osteotomy was designed on skull resin model. According to the preoperative design, the patients underwent Le Fort I osteotomy and mandibular ramus osteotomy. The internal mandible distractor was embedded onto the osteotomy position. The occlusal titanium pin was implanted. Distraction were carried out by mandibular-driven simultaneous maxillo-mandihular distraction 5 days after operation.

RESULTSThe distraction in five patients was complete as designed. No infection and dysosteogenesis happened. The longest distance of distraction was 28 mm, and the shortest distance was 16 mm. The facial asymmetry deformity was significantly improved at the end of distraction. The ocelusal plane of patients obviously improved.

CONCLUSIONSRapid prototyping technology is helpful to design precisely osteotomy before operation. Mandibular-driven simultaneous maxillo-mandibular distraction can correct hemifacial microsomia. It is worth to clinical application.

Objective To compare the efficacy of 18F-FDG PET/CT, 99Tcm-MDP bone scintigraphy (BS), and combination of the two techniques (PET/CT + BS) for detecting bone metastasis by ROC curve analysis. Methods All 296 patients with various cancers, who underwent both 99Tcm-MDP BS and 18F-FDG PET/CT within two months, were retrospectively analyzed. These images were interpreted according to 5-point scale (0: definitely negative, 1: probably negative, 2: equivocal, 3: probably positive, 4:definitely positive for bone metastasis), and the scale of PET/CT + BS was the sum of PET/CT and BS. In light of the confirmed diagnosis derived from pathology or follow-up, ROC curve analysis was performed.The area under the ROC curve (AUC) was compared by z-test. Results Of 296 cases, 61 (20.6%) were confirmed as bone metastases and 235 (79.4%) were negative. The AUC were 0. 919 (95% confidence interval (95% CI) :0. 867 - 0. 971) for BS, 0. 949 (95% CI: 0. 906 - 0. 991) for PET/CT, and 0. 994 (95% CI: 0.988-0.999) for PET/CT + BS, rctrospectively. The AUC of PET/CT + BS was statistically significantly larger than that of BS (z=2. 866, P=0.004) or PET/CT (z =2.027, P=0.043), while the AUC of PET/CT was larger than that of BS, but no statistically significance (z = 0. 881, P = 0. 378) was showed. The optimal sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value(NPV) were 90. 2% (55/61), 85. 1% (200/235), 86. 1% (255/296), 61. 1% (55/90), 97. 1%(200/206) for BS, 88.5% (54/61), 97.0% (228/235), 95.3% (282/296), 88.5% (54/61), 97.0% for PET/CT, and 98.4% (60/61), 95.7% (225/235), 96.3% (285/296), 85.7% (60/70) for PET/CT + BS,respectively. The specificity (χ2 = 19.862, P<0. 001), accuracy (χ2 = 23. 361, P<0.001) and PPV (χ2 =11. 791, P =0.001) of PET/CT + BS were significantly higher than those of BS, the sensitivity of PET/CT +BS was significantly higher than that of PET/CT (χ2 =4.167, P=0.031). Compared with BS, PET/CT had a higher specificity (χ2 = 19.600, P<0. 001), accuracy (χ2 = 13. 755, P <0. 001), PPV (χ2 = 13. 608, P <0. 001), but their sensitivity showed no statistically significant difference (χ2 = 0, P = 1. 000). Conclusions The efficacy of 18F-FDG PET/CT for detecting malignant bone metastasis was superior to that of 99Tcm-MDP BS alone. The detection ability can be obviously improved by combination of the two techniques.

Objective To evaluate the nutritional status of iodine of pregnant and lactating women in coastal and inland areas of Zhejiang province,and to provide scientific basis for iodine supplementation.Methods In 2009,five coastal cities,five coastal counties and three inland areas from Zhejiang province were selected by the cluster sampling method,and one sub-district(township) was randomly selected in each city (county),then one community (village) was randomly selected in each sub-district (township).Thirty pregnant women,thirty lactating women and fifty children aged 8 - 10,were randomly selected in each community(village) as the investigation objects to collect instant urine samples to detect urine iodine,and to collect thirty resident edible salt and some water samples to detect salt iodine and water iodine,if the numbers of water source were more than 5 then 1 water sample was collected by their location of east,south,west,north and center in each community(village),otherwise,the numbers of water samples collected were equal to the number of community (village).Results The medians of salt iodine of coastal city,coastal county and inland area were 28.42,25.29,and 33.24 mg/kg,respectively,and the medians of water iodine correspondingly were 5.41,11.52,and 2.80 μg/L,respectively.The medians of urinary iodine of pregnant and lactating women in Zhejiang province were 148.72 and 161.34 μg/L,respectively,which were less than that of children aged 8 - 10(231.02 μg/L,Z =8.57,8.24,all P ＜ 0.017).The medians of urinary iodine in pregnant women from different areas were ranked in order as inland areas(211.42 μg/L),coastal counties (150.51 μg/L) and coastal cities (123.33 μg/L,Z =2.80,5.31,2.42,all P ＜ 0.017),and in lactating women,the medians of urinary iodine in inland areas( 197.43 μg/L) was higher than that in coastal cities( 139.64 μg/L,Z =4.03,P ＜ 0.017).Conclusions The overall levels of iodine nutrition in lactating and pregnant women in Zhejiang province are in the appropriate level,but that of the pregnant women in the coastal cities is inadequate.

Objective To investigate the efficacy and safety as well as the effects of rituximab on B-lymphocytes and anti-platelet glycoprotein-specific antibodies,in patients with steroid-resistant idiopathic thrombocytopenic purpura(ITP).Methods Twelve steroid-resistant ITP patients,16 to 54 years old,received intravenous rituximab at the dose of 375 mg/m2 once-weekly for 4 weeks.Lab studies included CBC,serum concentrations of IgG,IgM and IgA.CD+3,CD+4,CD+8,CD+19,CD+20 cell numbers were assayed by flow cytometry and anti-platelet glycoprotein-specific antibodies(GP Ⅱ b/Ⅲ a,GP Ⅰ b/Ⅸ)were assayed by monoclonal antibody-specific immobilisation of platelet antigens prior to and following rituximab therapy.Results A complete response(platelet counts ≥100×109/L)was observed in 4 cases,a partial response (platelet counts between 50 and 100×109/L)in 3 cases,a minor response(platelet counts between 30 and 50×109/L)in 2 cases,and non response(platelet counts＜30×109/L)in 3 cases.Responses were sustained 0.5 to 12 months(median 5 months).After 4 weeks of rituximab therapy,anti-platelet glycoprotein-specific antibodies(GP Ⅱ b/Ⅲ a,GP Ⅰ b/Ⅸ)disappeared except one NR patient and CD+19/CD+20 cells were almost depleted in all patients(295.0±86.4)×106/L vs(4.1±2.2)×106/L(P＜0.01).As expected,the T cell counts,and the serum concentrations of IgG,IgM and IgA were not changed after therapy.No severe side effects were observed.Conclusion Rituximab may be an effective and safe treatment for adults with steroid-resistant ITP.

Objective To investigate the effects of δ-opioid receptor agonist DADLE (D-Ala2-D-Leu5-enkephalin) on the hemodynamics and oxygen metabolism in rats with sepsis. Methods Eighty healthy male SD rats were randomly divided into 4 groups ( n = 20 each) : sham operation group (group S), sepsis group (group SEP) ,DADLE, group and DADLE2, group. Sepsis was induced by cecum ligation and puncture (CLP) in SEP, DADLE,and DADLE2 groups. In DADLE1 and DADLE2 groups, 0.5 mg/ml DADLE 10 mg/kg was injected intraperitoneally (IP) 0.5 h before CLP and immediately after CLP respectively. Mean arterial pressure (MAP), left ventricular systolic pressure (LVSP) and ± dp/dtmax were recorded at 0, 2, 4 and 6 h after CLP (T1-4). Blood samples from left common carotid artery and right external jugular vein were collected at T4 for blood gas analysis. The cardiac index (CI), O2 delivery (DO2), O2 consumption (VO2) and O2 extraction rate (ERO2) were calculated.Results Compared with group S, MAP and LVSP were significantly increased at T2, while decreased at T3,4, and ± dp/dtmax was significantly increased in group SEP, MAP was significantly increased at T2, while decreased at T3,4, LVSP was significantly increased at T2,3, while decreased at T4 , and ± dp/dtmax was significantly increased in DADLE, and DADLE2 groups, and CI, DO2 and VO2 were significantly decreased and ERO2 was increased in SEP, DADLE, and DADLE2 groups (P＜0.05). Compared with group SEP, MAP, LVSP and ± dp/dtmax at T3,4 and CI, DO2 and VO2 were significantly increased, while ERO2 was significantly decreased in DADLE1 and DADLE2 groups (P ＜ 0.05). There was no significant difference in the parameters mentioned above between DADLE1 and DADLE2 groups ( P ＞ 0.05). Conclusion δ-opioid receptor agonist DADLE can obviously improve the hemodynamics and oxygen metabolism in septic rats.
