ObjectiveTo explore the clinical and epidemiological value of semi-quantitative regional cerebral blood flow(rCBF)imaging in children with school phobia. Methods A total of 20 cases diagnosed with school phobia were examined with rCBF.Twelve were males and the other 8 were females.The mean age was(14.2?2.1)years(11-18 years).Semi-quantitative analysis methods were used to investigate the correlations among gender,age and rCBF. ResultsThere were significant differences in the rCBF of right fronto-parietal lobe,right occipital lobe,caput and putamen,left thalamus and hippocampus,and temporo-occipital lobe between males and females(P0.05).Only the PI of left temporo-parietal lobe of those ≥ 15 years old was significantly different from that of those

Objective To explore the clinical manifestations of ultrasonography(US),99mTc-methoxyisobutylisonitrile(99mTc-MIBI),and 131I whole body scan(131I-WBS)of patients with differentiated thyroid carcinoma(DTC)and cervical lymph node metastasis.Methods A total of 117 cases received examinations of US and 99mTc-MIBI before uses of 131I and received 131I-WBS after 6 d of 131I treatment.Combined with serum thyroglobulin(Tg),131I-SPECT/CT,lymph node biopsy and clinical follow-up of patients,cervical lymph node metastases were identified.Results In 117 patients,the sensitivity of US,99mTc-MIBI and 131I-WBS were 76.5%,67.1% and 83.5%(P

0.05)between the recurrent rate[2.2%(10/463)]of the CR patients with lung metastasis and the progression rate of the 152 patients.Conclusions After normalization of ?-hCG titer,patients whose lung tumors remained unchanged even after several additional courses of chemotherapy should be considered as CR patients.Follow-ups should be strictly carried out on these patients,especially at around 6 months after the completion of treatment,and particularly for high-risk and drug-resistant choriocarcinoma patients.

Objective To explore the role of serum S-100B concentration of umbilical cord blood and blood on the 24 h after admission in the early diagnosis and development of newborn hypoxic-ischemic encephalopathy(HIE).Methods Forty-six HIE newborns(31 cases with mild HIE and 15 cases with moderate and severe HIE)were selected as HIE group,and 43 normal full-term newborns were selected as control group.The umbilical cord blood sample and blood sample were aquired on the 24 h after admission.The serum S-100B concentration was detected by enzyme-linked immunosorbent assay(ELISA)analysis.Results 1.There was no significant difference of serum S-100B concentration between the male sub-group and female sub-group of normal group and their birth weight had no significant relative to the serum S-100B concentration.2.The serum S-100B concentration of umbilical cord blood of control group and HIE group were(1.03?0.32)and(2.53?1.1)?g/L,respectively,there was significant difference between two groups(t'=8.848 P

To clone the 2-C-methyl-D-erythritol 4-phosphate cytidylyltransferase (TwMCT) full length cDNA from Tripterygium wilfordii, the specific primers were designed according to the transcriptome data and the LCPCR were carried out. After a series of bioinformatics analysis on the TwMCT, the MeJA induced expression content were investigated by real-time fluorescence quantification polymerase chain reaction (RT-qPCR). The result showed that the full of TwMCTcDNA was 1 318 bp nucleotides encoding 311 amino acids. The molecular weight of the deduced TwMCT protein was about 34.14 kDa and the theoretical isoelectric point was 8.65. Result of the RT-qPCR analysis indicated that the content of TwMCT mRNA expression in T. wilfordii suspension cell was rising after treating with MeJA and reached the maximum in 24 h. Cloning and analyzing TwMCT gene from T. wilfordii provided gene element for studying the function and expression regulation of secondary metabolites.

OBJECTIVETo systematically review the effectiveness of minimally invasive total hip arthroplasty (MIS-THA) versus traditional total hip arthroplasty (THA) in patients with hip diseases.

METHODSThrough a method of combining Free words and keywords,we searched databases including PubMed,The Cochrane Library, EMbase,Web of Science, CBM , CNKI and Wanfang Data for randomized controlled trials (RCTs) on the comparison between MIS-THA and THA for hip disease from inception to June, 2014. Two reviewers independently screened literatures according to the inclusion and exclusion criteria, extracted data and assessed the quality of the included studies according to the "bias risk assessment" tool recommended by Cochrane Handbook 5.0 for Systematic Reviews. Then, meta-analysis was performed using RevMan 5.3 software.

RESULTSThirteen RCTs involving 1 213 cases of surgeries and total 1 284 hips (MIS-THA: n = 631; THA: n = 653) were identified. The results of meta-analysis showed that statistically significant differences were found in Harris hip score on the 3rd month after operation [MD = 8.37, 95% CI (6.02,10.72)], Hematocrit [MD = 0.02, 95% CI (0.01, 0.03)] and Hemoglobin [MD = 0.50, 95% CI (0.16, 0.85)] at the 48th hour after operation, changed value of femoral offset [MD = 0.30, 95% CI (0.04, 0.56)] between two groups. In the change value of femoral offset, THA was better than MIS-THA; There were no statistically significant differences between two groups in Harris hip score at 1st year after operation [MD = 3.26, 95% CI (-3.25, 9.76)], WOMAC score [MD = -0.53, 95% CI (-3.67, 2.60)] and Oxford score [MD = 1.34, 95% CI (-3.46, 6.13)] at the 6th week after operation, Hematocrit at the 8th hour after operation [MD = -0.01, 95% CI (-0.02, 0.00)], the incidence of hip varus [RR = 0.82, 95% CI (0.45,1.52)] and dislocation [RR = 1.40, 95% CI (0.48, 4.12)].

CONCLUSIONTHA brings less trauma, less hemorrhage and better early clinical outcome compared with MIS-THA, but the difference of the complication rates between the two groups is similar.

AIM: To study the effects of Sodium Hyaluronate (HA) and Bion Tears on corneal thickness in adult myopic patients.METHODS: A total of 38 cases (76 eyes) were involved in this study. Three consecutive corneal measurements (the thinnest point of the cornea,THN) were evaluated before and half an hour after the instillation of one drop of HA in one eye and Bion Tears in the other at random with the Orbscan Corneal Topography System II (Orbscan,Inc,Salt Lake City,UT,USA,Version 3.00E).RESULTS: There were no significant between-group differences in baseline variable (t=0.264). Thirty minutes after the instillation of HA and Bion tears,THN were significantly increased by 5.57±7.00μm (t=4.906,P<0.01) and 7.89±7.64μm (t=6.369,P<0.01) respectively. However,there were no between-group differences in THN changes(t=1.381,P>0.05).Increase in the corneal thickness were found in 32 eyes (84%) and 33 eyes (87%) for the HA and Bion tears group,respectively.CONCLUSION: Artificial tears including HA and Bion Tears can significantly increase the corneal thickness in a short period of time. Corneal thickness can be used as one of the objective indices for evaluating the quality and therapeutic role of artificial tears.
