Objective To evaluation of curative effect of Yiqi-Wenshen decoction combined with salmon calcitonin subcutaneous injection for the patients with postoperative bone atrophy after calcaneal fracture.Methods According to the inclusion criteria, 120 patients with calcaneal fracture were randomly divided into 2 groups, 60 in each group. The control group received the subcutaneous injection of salmon calcitonin, and the combined group received the control group treatment plus Yiqi-Wenshen decoction. Both groups were treated for 6 weeks. The X-ray was used to detecte the local bone density of limbs, and the foot function scores of ankle function and the changes of clinical symptoms and signs before and after treatment were observed.Results After treatment, joint pain (2.8 ± 1.1vs. 3.6 ± 1.1,t=4.129), tenderness (1.0 ± 0.5vs. 1.4 ± 0.7,t=3.297), the color change of (1.5 ± 0.8vs. 2.0 ± 0.6,t=3.117) score in the combined group were significantly lower than those in the control group (P<0.05). The degree of swelling (112.5 ± 11.8 cm3vs. 122.5 ± 13.6 cm3,t=3.816) in the combined group was significantly lower than that in control group (P<0.05). The bone mineral density (0.762 ± 0.020 g/cm2vs. 0.722 ± 0.023 g/cm2,t=3.803,P<0.05) in the combined group was significantly higher than that in the control group. The effect rate of the combined group was 90% (54/60), and the control group was 70%. There was significant difference between 2 groups (χ2=7.500,P=0.006). The effect rate of ankle joint function of the combined group was 83.3% (50/60), and the control group was 70% (42/60). There was significant difference between 2 groups (χ2=4.444,P=0.035).Conclusions The Yiqi-Wenshen decoction combined with subcutaneous injection of salmon calcitonin could relieve the pain, swelling and other symptoms of the patients with bone atrophy after calcaneal fractures, and could benefit the recovery of ankle joint function.

Objective To study the clinical and imaging features of chlamydial pneumonia in newborns.Methods Medical records,chest X-Ray and CT findings of 17 neonates with chlamydia pneumonia were reviewed.The age was ranged from 9.0 to 28.0 days with mean of ( 16.8 ± 5.8 ) days.There were 11males and 6 females.Sixteen were full term infants and one was born post term.All babies were examined with chest X-ray film,and 13 patients also underwent chest CT scan.Serologic test using immunofluorescence method for Chlamydia IgG and IgM antibodies were performed in all patients.Results All newborns presented with cough but without fever.Positive results of the serologic tests were demonstrated.Chest films showed bilateral hyperventilation in 10 patients,diffuse reticular nodules in 10 patients including nodules mimicking military tuberculosis in 7 patients,and accompanying consolidation in 9 patients.CT features included interstitial reticular nodules in 13 patients with size,density,and distribution varied.Subpleurul nodules ( 11patients) and fusion of nodules ( 10 patients ) predominated.Bilateral hyperinflation was found in 10 patients,which combined with infiltration in 12 patients,thickening of bronchovascular bundles in 10 patients,and ground glass sign in 5 patients.No pleural effusion and lymphadenopathy was detected in any patient.Conclusions Bilateral hyperinflation and diffuse interstitial reticular nodules were the most common imaging features of neonatal chlamydial pneumonia.The main clinical characteristic of neonatal chlamydial pneumonia is respiratory symptoms without fever,which is helpful to its diagnosis.

Objective To investigate the CT imaging findings of thymus and thyroid gland involved in Langerhans cell histiocytosis(LCH) of pediatric patients. Methods CT image findings in pediatric patients with LCH confirmed by pathology and clinical diagnosis from January 2006 to February 2015 were retrospectively analyzed. By radiography, 38 cases' thymus gland were involved and 8 cases' thyroids gland were involved. Results Plain CT scan for thymus gland involved patients revealed 9 cases were shown as hyperplasia, 17 cases were shown as calcification, 9 cases were shown as hyperplasia with calcification, 1 case was shown as cavity, 1 case was shown as hyperplasia with calcification and cavity and 1 case was shown as hyperplasia with calcification and low density. Enhanced CT scan for thyroid gland involved patients showed bilateral or unilateral enlargement of thyroid gland with heterogeneous low density and unobvious enhancement. Conclusions Finely calcifications were the most common CT findings on thymus gland involved in LCH and might without hyperplasia. CT imaging of thyroid LCH exhibited an enlarged or normal size and abnormal density in the thyroid gland with adjacent soft tissues involved.

Objective To investigate the effect of HbA1c meeting the standard or not on microalbuminuria,blood lipids and liver enzymes in patients with type 2 diabetes.Methods A retrospective analysis was performed on 457 subjects who had type 2 diabetes.They were divided into substandard group and standard group according to HbA1c result.The general information and relevant laboratory indicators of patients were.collected and compared between two groups.Results The microalbuminuria,serum triglyceride and liver enzymes (glutamyl transpeptidase,alkaline phosphatase,aspertate aminotransferase) were significantly different between two groups [ (189.8 ± 235.3) mg/dl vs (38.9 ± 85.5) mg/dl,(2.64 ± 2.99) mmol/L vs (2.02 ± 1.50)mmol/L,(41.7 ±52.9)U/L vs (29.7 ±24.9)U/L,(83.6 ±28.6) U/L vs (74.3 ±25.8)U/L,(26.7 ±19.1)U/L vs (22.0 ±10.5) U/L,P ＜0.05].HbA1c level was positively correlated with microalbuminuria,glutamyl transpeptidase and alkaline phosphatase (r =0.209,0.115,0.11,P ＜0.01).The microalbuminuria was an independent risk factor of affecting HbA1c to reach the standard (OR = 1.009,P ＜0.05).Conclusions HbA1c meeting the standard or not can influence many factors except blood glucose.

Purpose To assess the value of 2-(fluorine-18) fluroro-2-deoxy-D-glucose (FDG)-PET/CT on the diagnosis of cervical lymphadenopathy.Materials and Methods FDG-PET/CT was performed in 38 patients with cervical lymphadenopathy from June 2006 to October 2008. The standard uptake value (SUV) of abdominal lymph nodes (SUVmean) and SUV of normal cervical lymph nodes (SUVneck) were measured. All malignant lymph nodes were pathologically proved.Results 35 enlarged lymph nodes detected in 30 patients demonstrated higher SUV than normal neck tissue. 7 benign lymph nodes were not visualized and 4 benign ones were visualized.The accuracy of PET/CT in indicating the malignant lymph nodes was higher than that of ultrasonography, CT and MRI (P<0.001).Conclusion PET/CT is an effective tool in differentiating malignant lymph nodes from benign ones for patitents with lymphadenopathy.

Objective To evaluate the feasibility of model-based iterative reconstruction (MBIR) in low-dose chest CT (80 kV) examination in children.Methods Forty-four children who had post-operation scoliosis and received low dose chest CT scans were included.The fix tube voltage was 80 kV,fix current was 50 mA.Images were reconstructed with MBIR (observation group).The pre-operation scan were used 120 kV and 50 mA for acquisition,and images were reconstructed with filtered back-projection (FBP) mehed (control group).The subjective quality of the images was independently evaluated by two radiologists.Objective noises in the muscle and lung field were measured,the SNR,CNR were calculated,and the CTDIvol was record.Results The subjective noise score in the observation group was significantly higher than that in the control group (P＜0.05).Objective noise reduced about 40.36％,SNR increased 72.37％,CNR increased 78.69％,CTDIvol decreased by 66.52％,all of which had statistical difference between both groups (all P＜0.001).Conclusion Low-dose chest CT (80 kV) examination in children can meet the requirements of diagnosis for children.

A phytochemical investigation on the roots and stems of Litsea cubeba led to the isolation of seven isoquinolone alkaloids. By spectroscopic analysis and comparison of their 1H and 13C-NMR data with those in literatures, these alkaloids were identified as (+)-norboldine (1), (+)-boldine (2), (+)-reticuline (3), (+)-laurotetanine (4), (+)-isoboldine (5), (+)-N-methyl-laurotetanine (6), and berberine (7), respectively. Among them, 7 was isolated from the genus for the first time. The evaluation of these compounds showed weak anti-inflammatory activity against NO production in RAW 267.4 and BV-2 cells.

Objective To study the significance of the cerebrospinal fluid(CSF)lactate level in diagnosing neonatal bacterial meningitis(BM). Methods The CSF samples were collected from neonates admitted to Neonatal Ward of Children's Hospital of Fudan University between January 2014 and March 2015. CSF lactate and glucose con-centrations were measured with blood - gas analyzer. CSF and serum glucose levels were measured with glucometer. The enrolled neonates were divided into 2 groups based on CSF culture,CSF white blood cells(WBCs)and clinical presenta-tion:observation group(neonates with BM)and control group(neonates without BM). Statistical analysis of data was performed with Stata 12. 0. Results A total of 93 infants(16 assigned to observation group and 77 assigned to control group)met the inclusion criteria. Neonates in observation group had higher median CSF lactate level(4. 2 mmol/ L)and CSF lactate/ glucose ratio(L/ Gcsf)(2. 32 mmol/ L),than those in control group(1. 3 mmol/ L,0. 52),and there were significant differences(Z = - 6. 19,- 5. 92,all P ﹤ 0. 05). CSF glucose levels were lower in observation group(me-dian,1. 25 mmol/ L)than those in control group(median,2. 5 mmol/ L),and the difference was significant(Z = 4. 97, P ﹤ 0. 05);CSF/ serum glucose ratio(CSF/ Sglu)were lower in observation group(median,0. 44 vs 0. 81 in control group),and the difference was significant(Z = 4. 43,P ﹤ 0. 05). The optimal CSF lactate cutoff point of 2. 2 mmol/ L had a positive predictive value(PPV)of 72. 7% and negative predictive value(NPV)of 100. 0% for bacterial meningi-tis. The optimal L/ Gcsf cutoff point of 1. 24 had a PPV of 94. 1% and NPV of 100. 0% . The optimal CSF glucose cutoff point of 2. 0 mmol/ L had a PPV of 65. 0% and NPV of 95. 9% . The optimal CSF/ Sglu cutoff point of 0. 6 had a PPV of 60. 0% and a NPV of 96. 9% . Conclusion CSF lactate may be an excellent biomarker for early diagnosis of neo-natal BM.

Objective To investigate the value of three-dimensional speckle tracking imaging (3D-STI) in assessment of left ventricular (LV) strains. Methods Thirty healthy young adults examined by two-dimensional speckle tracking imaging (2D-STI) and 3D-STI. And the results of LV measurements were compared, which included mean peak systolic longitudinal strains, radial strains and circumferential strains. Also, the time consumption of these two methods was compared. Results The time needed for 3D-STI in acquisition and analysis of the images were (309.3±23.4)s, (305.5±11.2)s, while the time for 2D-STI were (490.6±14.4)s, (1261.4±39.9)s. The differences were signiifcant(t=-21.81, 69.94, both P<0.01). The global mean peak systolic radial strains was (48.59±7.68)%by 3D-STI and (33.25±7.27)%by 2D-STI. The difference was signiifcant(t=9.16, P<0.01). The global mean peak systolic longitudinal and circumferential strains were (-17.66±3.14)%, (-17.13±2.29)% by 3D-STI and (-21.35±2.46)%, (-21.97±3.84)% by 2D-STI. The differences were signiifcant(t=5.33, 5.99, both P < 0.01). The 3D-STI strains were different at different levels of LV. The longitudinal, circumferential and radial 3D-STI strains were largest at middle levels. However, 2D-STI strains didn′ t show such trend. Peak strains measured by 3D-STI and 2D-STI showed high inter-observer and intra-observer agreement in Bland-Altman chart. Conclusion 3D-STI is a novel, convenient and reproducible method to evaluate the strains of LV.
