OBJECTIVETo investigate the incidence of depression and its etiological factors in patients with cryptorchidism 6-16 years after surgical treatment.

METHODSUsing Self-Rating Depression Scale and Correlation Factor Questionnaire, we investigated the incidence of depression symptoms among 70 patients with cryptorchidism 6-16 years after surgical treatment and another 70 healthy males as controls, and analyzed the related factors of depression symptoms.

RESULTSThe incidence rate of depression symptoms was 50% in the cryptorchidism patients postoperatively, extremely significantly higher than 4.3% in the control group (χ2 = 23.5, P <0.01). Multiple stepwise regression analysis showed that the main risk factors of depression symptoms were worries about natural fertility (F = 15.8992, P <0.01), dissatisfaction with scrotal appearance (F = 4.6003, P <0.05), and the status of being married (F = 4.1002, P <0.05).

CONCLUSIONSymptoms of depression often occur in cryptorchidism patients after operation, and the major etiological factors are infertility, dissatisfaction with scrotal appearance, and the status of being married.

Objective To explore the correlation between CTvolume rendering (VR) statistics and living age and to build the mathematical models for skeletal age evaluation based on the grow th rules of medi-al clavicular epiphysis of teenagers in China. Methods The thin layer CTscan and VR3D imaging re-construction of both sides of sternal ends of clavicles were exam ined for 684 teenagers aged from 15 to 25 in East and South China. The parameters of sternal end of clavicle including the longest diameter of epiphysis, the longest diameter of metaphysis, their length radio, area of epiphysis, area of meta-physic, their area ratio, and other data were measured and calculated in order to establish mathematical models of skeletal age evaluation. Fifty trained subjects were tested to verify the accuracy of the math-ematical models. Results In the same age group, the length ratio and the area ratio had significant dif-ference in genders (P<0.05). The established mathematical models showed that the grow th rules of medial clavicular epiphysis were highly correlated with the living ages. The accuracies of these models were higher than 70.5% (±1.0 year) and 82.5% (±1.5 year). Conclusion The mathematical models have easy operability and high accuracy. It can be used to confirmand sustain the conclusion of atlas method. M eanw hile, it is of great significance to study the other single skeletal age evaluation in the future.

Objective To summarize the subtle anatomical structures of the normal nasal bone in mul-ti-slice spiral CT (MSCT) image through the observation of the three-dimensional images. Methods One hundred and twenty volunteers who had no nasal trauma and disease history were collected. The nasal was scanned using MSCT. Raw data was reconstructed into bone window images (slice thickness 0.6 mm, slice interval 0.5 mm), and then the images were imported into Syngo Imaging XS software to recon-struct three-dimensional images and to summarize the nasal bone ’s subtle anatomical structures. Results The subtle anatomy of normal nasal bone generally included four seams, two holes and one edge. The four seams were left and right nasal-maxillary suture, nasal-frontal seam, and internasal suture. The two holes were left and right nasal aperture. The edge of the nasal was the lower edge of the nasal bone. In addition, there was suture bone in internasal suture in some normal nose. The nasal aperture mostly was hole-like, but some nasal apertures were line shape. The nasal edge can be divided into flat type, wave-shaped type, inverted spike type, hook-shaped type and others. Conclusion The anatomy diversity and individual differences in nasal bone are large. MSCT and three-dimensional image reconstruction techniques, combined with the history of trauma could distinguish between the normal anatomy and fractures.

Emergency in public health is one major issue relating to the national economy and the people's livelihood.In dealing with the key technologies of detects,diagnosis,disinfection,prevention and control,it is wise to syncretize the correlated subjects in nucleus,chemistry and biology,improve the support condition of teaching,strengthen the reform of teaching contents,add some lessons of emergency treatment,make emergency equipments,and form the ability of rapid diagnosis on the spot and precise identifying in lab,for cultivating the students'capability of spot handling,organization and command,and furthermore exploring and practicing the training pattern of the public heath talent with high quality and emergency ability in our country.

This study was aimed to clone human intercellular adhesion molecule-1 (ICAM-1) gene, to transfect the constructed eukaryotic expression vector ICAM-1-GFP into CHO cells, as well as to detect ICAM-1-GFP expression in CHO cells binding with Molt-4 cells. ICAM-1 cDNA gene was amplified by RT-PCR and inserted in PMD(18)-T vector. Then ICAM-1 cDNA from pMD18-ICAM-1 vector was subcloned into eukaryotic expression vector pEGFP-C1 to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing were used to confirm the recombinant vector. After stable transfection of CHO-K1 cells with the recombinant vector, the expression and subcellular localization of ICAM-1-GFP were detected by RT-PCR, flow cytometry and fluorescence microscopy. The function of ICAM-1-GFP fusion protein was assessed by the binding of ICAM-1-GFP/CHO cells to Molt-4 cells. The results showed that 1622 bp full-length ICAM-1 cDNA obtained and was successfully ligated with pMD(18)-T-vector, subcloned to construct recombinant ICAM-1-pEGFP-C1 vector. Restriction analysis and DNA sequencing indicated that recombinant ICAM-1-GFP was successfully constructed and ICAM-1-GFP was expressed stably in CHO cells. ICAM-1-GFP expression was only observed in the cytoplasm of ICAM-1-GFP/CHO cells by fluorescence microscopy. The ICAM-1-GFP/CHO cells were bound to PMA-treated Molt-4 cells. The expression of MEM-148 was very weak in PMA-treated Molt-4 cells. It is concluded that the ICAM-1-GFP eukaryotic expression vector has been constructed successfully and expresses stably in CHO cells. PMA can increase the binding of Molt-4 cells to ICAM-1-GFP/CHO cells by inducing specialized form of ICAM-1 clustering.

Cytometric bead array (CBA) is a new analytical technique, which can achieve real-time and rapid detection of targeted components in a small amount of sample. With many advantages of high throughput screening, high specificity and sensitivity, low cost, easy operation and good repeatability, this CBA technique has been widely used for the detection of various components in foods, agricultural products and environmental samples. Recently, it has got significant development in rapid detection of small molecules. This review briefly introduced the theory of CBA technique, summarized the application in the analysis of small molecules, such as mycotoxins, pesticide residues, shellfish toxins, and then prospected the application of trace small molecules detection in the complex matrices of traditional Chinese medicine and the development trend of it.
