OBJECTIVETo investigate the anxiety disorders and influence factors that occur in adolescent patients with cleft lip and palate and to provide theoretical foundation for mental intervention.
METHODSA total of 120 adolescent patients with cleft lip and palate were investigated using a general information questionnaire, the self-rating anxiety scale, and the social support rating scale (SSRS). The influence factors of anxiety disorders were analyzed.
RESULTSThe effective questionnaires were 119. The occurrence rate of anxiety disorder in adolescent patients was 49.6% (59/119), and the occurrence rates of mild, moderate, and severe anxieties were 41.2% (49/119), 7.6% (9/119), and 0.8% (1/119), respectively. The gender, residential area, disease category, family status (one child or no children), and incidence rate of anxiety disorder in patients were statistically different (P<0.05). The SSRS scores of patients with anxiety disorder were lower than those of patients without anxiety disorder (P<0.05). Multiple regression analysis showed that gender and social support were predictive factors of the occurrence of anxiety disorder (R=0.318).
CONCLUSIONA high anxiety disorder rate occurred in adolescent patients with cleft lip and palate. dender and social support were important influencing factors for anxiety disorder. In the after-mental intervention, considerable attention should be given to the anxiety disorders of patients and improve their mental health.

Objective To observe the serum γ-glutamyltransferase (γ-GGT) levels in patients with chronic hepatitis B virus (HBV) infection in different immune status and investigate their relationship with HBV DNA loads and ALT levels. Methods Blood samples were collected from 191 patients with chronic HBV infection in different immune status, including inactive HBV carrier state (group B,n = 55), immune tolerance phase (group C, n=47), HBeAg-negative CHB (group D, n =17), immune-reactive phase (group E, n=72) and 61 healthy individuals ( group A) for the detection of the serum γ-GGT, ALT level and HBV DNA loads. Results γ-GGT level were obviously higher in groups D and E than those in groups of A, B and C (P<0.01). Correlation analysis showed that the γ-GGT levels were positively correlated with serum ALT , AST levels in HBeAg-negative CHB and immune-reactive phase , but not correlated with HBV DNA loads. Conclusions The levels of γ-GGT are different during different immune status in patients with chronic HBV infection. The increased serum γ-GGT level may be an indicator for patients with chronic HBV infection entering immune active phase. The liver inflammation is the major impact factor to the γ-GGT levels.

Objective To find out the potential risk factor of plague in Wanzhou section of the Three Gorges Reservoir area, and to provide scientific basis for prevention and control of plague. Methods Rodents were captured by rat traps/cages at night and identified into species in Wanzhou section of the Three Gorges Reservoir area from 2001 to 2009. Flea was counted and serum antibodies against plague F1 of rats, cats and dogs were detected by indirect hemagglutination (IHA). Plague surveillances were performed in human beings and rats. Results The rodents captured belonged to 9 species, 2 families, 2 orders and 1 classes. The average indoor rodent density was 1.16% (961/82 558), and was 1.12% (1345/119 671) outdoors. Rattus norvegicus was the dominant species,accounting for 50.37%. The proportion of R. Flavipectus was 3.80% in 2004, 4.50% in 2008 and 10.12% in 2009,showing an increasing trend year by year. There were three kinds of mice infected fleas in Wanzhou, which including Xenopsylla cheopis, Leptopsylla segnis and Ctenocephalides felis. The average rate of flea infected mice was 1.18%(82/6959) and the total flea index was 0.036. No F1 antibody against plague was detected in 6959 dogs and 160 cats serum samples. Conclusions No plague is found in Wanzhou section of the Three Gorges Reservoir area. But R.Flavipectus, Xenopsylla cheopis and Leptopsylla segnis are dominant species in Wanzhou section, and the proportion of which shows an increasing trends year by year. There is a potential risk of plague outbreaks in Wanzhou section of the Three Gorges Reservoir area.

BACKGROUNDThe auditory brainstem implants (ABIs) have been used to treat deafness for patients with neurofibromatosis Type 2 and nontumor patients. The lack of an appropriate animal model has limited the study of improving hearing rehabilitation by the device. This study aimed to establish an animal model of ABI in adult rhesus macaque monkey (Macaca mulatta).
METHODSSix adult rhesus macaque monkeys (M. mulatta) were included. Under general anesthesia, a multichannel ABI was implanted into the lateral recess of the fourth ventricle through the modified suboccipital-retrosigmoid (RS) approach. The electrical auditory brainstem response (EABR) waves were tested to ensure the optimal implant site. After the operation, the EABR and computed tomography (CT) were used to test and verify the effectiveness via electrophysiology and anatomy, respectively. The subjects underwent behavioral observation for 6 months, and the postoperative EABR was tested every two weeks from the 1 st month after implant surgery.
RESULTThe implant surgery lasted an average of 5.2 h, and no monkey died or sacrificed. The averaged latencies of peaks I, II and IV were 1.27, 2.34 and 3.98 ms, respectively in the ABR. One-peak EABR wave was elicited in the operation, and one- or two-peak waves were elicited during the postoperative period. The EABR wave latencies appeared to be constant under different stimulus intensities; however, the amplitudes increased as the stimulus increased within a certain scope.
CONCLUSIONSIt is feasible and safe to implant ABIs in rhesus macaque monkeys (M. mulatta) through a modified suboccipital RS approach, and EABR and CT are valid tools for animal model establishment. In addition, this model should be an appropriate animal model for the electrophysiological and behavioral study of rhesus macaque monkey with ABI.

Objective To investigate the influences of Chinese herbal remedies (CHR) with the actions of replenishing qi and nourishing yin, and resolving mass and freeing the collateral vessels on renal nephrin-mRNA and ultrastructure in rats with early diabetes. Methods All SD rats were randomly divided into 6 groups including group 1 (with nephrectomy), group 2 (model), group 3 (with irbesatan), group 4 (with low-dose CHR), group 5 (with mid-dose CHR) and group 6 (with high-dose CHR). The relevant drugs or CHR were given intragastrically to different groups respectively. At the end of 6th week the quantity of 24-hour urine protein (UPro) and kidney function were detected. The pathological changes of renal cortex were observed by using transmission electron microscope (TEM) after HE staining. The expression of nephrin was determined by applying RT-PCR.Results There were pathological changes of diabetic nephropathy observed by the light microscope and TEM in group 2 and 1, which were alleviated in other 4 groups. The quantity of UPro decreased significantly in group 3, 4 and 5 compared with that in group 2 and 6 (P<0.05). The renal function was improved significantly in all treatment groups compared with that in group 2 (P<0.05). In group 3, 4, 5 and 6 the expression of nephrin-mRNA increased significantly compared with that in group 2 (P<0.05).Conclusion CHR with the actions of replenishing qi and nourishing yin, and resolving mass and freeing the collateral vessels have a protective effect on kidney in rats with diabetic nephropathy induced by STZ.

This study was designed to investigate the effect of hypoxia on preeclampsia(PE)by modulating the Src/Siglec-6/SHP2 signaling pathway in the cytoplasm of trophoblast cells.Mouse model of PE was established in normal control and Siglec-6 knockdown mice by L-NAME administration,with aims of studying the changes in vascular diameter of spiral arteries in vivo and examining the expression levels of Siglec-6,p-Src,p-Shp2 and p-ERK1/2 proteins in mouse uterine vascular tissues.While,the effect of Src/Siglec-6/SHP2 on the invasive proliferation of trophoblast cells was explored by culturing human chorionic trophoblast cells HTR-8/SVneo with hypoxia in vitro.In vivo experimental assays showed that the diameter of spiral arteries was reduced in the Siglec-6 knockdown group of mice,and the expression levels of Siglec-6,p-Src,p-SHP2 and p-ERK1/2 proteins were significantly reduced.In vitro hypoxic HTR-8/SVneo cell model results revealed that Siglec-6 overexpression could promote trophoblast cell invasion and proliferation by regulating p-Src,p-SHP2,p-ERK1/2,MMP2,P53 and P21.While,suppression of Src and SHP2 eliminated Siglec-6 overexpression-mediated Siglec-6,p-Src,p-SHP2 and p-ERK1/2 expression,and inhibited the ability of Siglec-6 overexpression to mediate trophoblast invasion and proliferation.Taken together,Siglec-6 plays an important role in preeclampsia,and can alleviate preeclampsia by promoting trophoblast invasion and proliferation through the Src/SHP2 signalling pathway.

Critical ultrasonography is widely used in ICU and has become an indispensable tool for clinicians. However, besides operator-dependency of critical ultrasonography, lack of standardized training mainly result in the physicians′ heterogenous ultrasonic skill. Therefore, standardized training as well as strict quality control plays the key role in the development of critical ultrasonography. We present this quality control standards to promote better development of critical ultrasonography.
