Objective: To observe the clinical effects of pediatric tuina plus Chinese medicine for exogenous fever in children. Methods: A total of 150 children withexogenous fever were randomly divided based on the random digital table into a control group (75 cases) and a treatment group (75 cases). The control group was treated with oral Xiao'er Chaigui Tuire Keli (<1 year old, 0.5 bag/time; 1-3 years old, 1 bag/time; 4-6 years old, 1.5 bags/time), 4 times/day. The treatment group was treated with pediatric tuina plus the intervention of the control group. The amount and usage of Chinese medicine were the same as those of the control group; tuina was conducted 1 time/day. The clinical effects and adverse reactions were observed after 3 d of treatment in both groups. The recurrence was observed within 7 d after the end of treatment. Results: The total effective rate was 92.0％ in the treatment group and 81.3％ in the control group. The difference between the two groups was statistically significant (P<0.05). There were no obvious adverse reactions in the two groups after treatment. The recurrence rate was 1.5％ in the treatment group and 13.1％ in the control group. The difference in the recurrence rate between the two groups was statistically significant (P<0.05). Conclusion: Pediatric tuina plus Chinese medicine is effective in treating children with exogenous fever.

The ability to induce hypersensity on leaves of tomato and the stability of double-plasmid of an harpin-producing, nitrogen-fixing engineered strain E4 were tested. Hypelsensitivity-inducing experiment indicated that the time and density of hypersensitivity-induction of E4 was similar to those of DH5, the positive control of pCPP430. Although E4 took the same time to induce hypersensitivity as 308R, another positive control of pCPP430, it induced weaker hypersen- sitivity on tobacco leaves. On tomato leaves, there was no difference in time and density of hypersensitivity between E4 and 308R (pCPP430). Results revealed that the two plasmids, pCPP430 and pMC73A, were unstable in host bacteria, with the losing rate of 100% at the 48th generation. The emergence probability of bacteria with either pCPP430 or pMC73A was almost the same.

Objective　To distinguish benign from malignant multiple vertebral collapses.Methods　171 vertebral collapses (77 benign,94 malignancy) were studied in 58 patients with T1WI,T2/T2WI,contrast enhancement T1WI with fat saturation.Pathologic result was available in 16 vertebras,including 10 malignancy and 6 benign.The remaining patients were performed 3～6 months follow-up to confirm the final diagnosis.The following MR characteristics were reviewed:(1)The shape and distribution of abnormal signal intensity.(2)The shape of antero-or poster-border of compressive vertebral body.(3)Paravertebral soft tissue mass.(4)The change of lesions signal intensity on T1WI,T2WI and contrast enhanced MRI with fat saturation.(5)Signal intensity increasing ratio after contrast enhancement.Results　The malignant vertebral compression fractures showed as the punch or patchy low signal intensity on T1WI distributing anywhere in the compressive body and enhancement.It had the convex posterior cortex,pedicle involved,paravertebral soft tissue mass.The benign vertebral compression fractures showed as the band linear hypo-or-iso-intensity in end-plate,enhanced (acute fracture)or unenhanced(old fracture),retropulsion of posterior cortex,no pedicle involved and paravertebral soft tissue.Conclusion　The most important MR characteristics for differentiation of malignant or bengin vertebral compression are the shapes and distributions of the abnormal signal intensities of vertebral collapses.The contrast enhancement T1WI with fat saturation is helpful for imaging diagnosis.

Objective To distinguish malignant from osteoporotic acute vertebral collapses at the single location. Methods Fifteen osteoporotic and sixteen malignant vertebral collapses were studied in thirty-one patients with T1 WI,gadolinium enhanced T1 WI and T2 WI MRI. All the patients had the follow-up periods of 3 ～ 6 months or pathologic results from biopsy. Results Seven findings were suggestive of osteoporotic: 1. The compression of vertebral body was severe. 2. The lesion extended to the whole vertebral body was uncommon. 3. The location of the lesion was closed to the end plate of the vertebral body and the anterior and/or posterior of the vertebra was straight or concave.The posterior bone fragment can be seen. 4. Pedicles were normal. 5. No epidural soft tissue mass. 6. The vertebral vein was normal. 7. The bandilike or flakelike enhancement under the end plate. Another seven findings were suggestive of malignancy: 1. The compression of vertebral body was mild. 2. The lesion extended to the whole vertebral body was common. 3. The anterior and /or posterior of the vertebra cortex was convex. 4. Pedicles were involoved. 5.Epidural soft tissue mass was usually seen. 6. The vertebral vein was involved and disappeared. 7. The lesion was usually nodulus enhancement. Conclusion To distinguish malignant from osteoporotic acute vertebral collapses,the MRI findings of the morphology and the shape of the lesion postcontrast are useful in the differentiation of solitary acute vertebral collapses.

Objective To discuss whether it is necessary to integrate metabolic indices into diagnosis of polycystic ovary syndrome(PCOS).Methods Taking ESHRE /ASRM diagnosis standard as gold standard,the case group composed of 51 women with PCOS and the control group composed of 47 women without PCOS were selected.By using classification tree C5.0,significant variables chosen by single factor analysis were used to establish a new diagnostic model which combined reproductive indices and metabolic indices.The validity and reliability of the new diagnostic model by using ROC curve analysis were evaluated.Finally,the consistence and difference between the new diagnostic model and the gold standard were analyzed.Results Single factor analysis chose 13 significant variables. ROC analysis showed an area under the curve of 0.930(P =0.000)and the optimal cut -off point was 0.190 with a sensitivity of 94.10%,a specificity of 91.50% and a consistency of 92.86%,which told us the new diagnostic model had superior validity and reliability.The two diagnostic methods had excellent consistence (Kappa =0.857,P =0.000)and there was no statistically significant difference (P =1.000).Conclusion Considering that whether metabolic indices are integrated into diagnosis of PCOS doesn′t change the diagnosis result,and it is unnecessary to integrate metabolic indices into diagnosis of PCOS.

This study was aimed to establish a fast determination method of main components in honey. Honey samples from difference production bases were used as study objects. Transmission and reflection spectra of different honey samples were collected with the Fourier transform near infrared spectrometer. The main components in honey (moisture content, fructose content, glucose content and reducing sugar content) were detected by the near infrared quantitative analysis technique. The near infrared quantitative analysis models of moisture content, fructose content, glucose content and reducing sugar content in honey were established by the partial least squares (PLS). The results showed that the correlation coefficient (r) of the moisture content, fructose content, glucose content and reducing sugar content in honey were 0.997 25, 0.973 90, 0.927 94 and 0.952 68, respectively. The root mean square error of prediction (RMSEP) were 0.165 (%), 0.564 (%), 1.300 (%) and 1.270 (%), respectively. It was concluded that determination of main components in honey by the near-infrared spectroscopy technology was a fast and nondestructive determination method with high accuracy, which can be used in the quantitative detection of main components in honey.
