OBJECTIVETo evaluate the effect of the pulsed Nd: YAG laser irradiation on the survival rate of human penodontal ligament fibroblast (PDLF) at different power and irradiation time settings, and to compare the morphological change of cells before and after irradiation.

METHODSThe cells were cultured and placed into the 96-well tissue culture plates. Cells were divided into groups according to the irradiation time (10 s, 20 s, 40 s, 60 s) and the output energy (0.5 W, 1.0 W, 1.5 W, 2.0 W, 2.5 W). After the irradiation, the cell number were counted and the survival rates were calculated. The correlation between the survival rate and irradiation time as well as power output was analyzed.

RESULTSNo significant reduction of survival rates were found in 10 s group, as well as in 20 s group with 0.5 W, 1.0 W setting. The increase of the power output and increase of the irradiation time caused significant reduction of cell survival rate (P <0.05). The irradiation time was more relevant to this reduction than the power output.

CONCLUSIONIt indicates that the laser irradiation may cause damage to PDLF and decrease the cell survival rate. The irradiation time is more related to this effect than the power output.

In this study, two school-aged children had an acute onset in spring and had the manifestations of fever, headache, vomiting, disturbance of consciousness, purpura and ecchymosis, and positive meningeal irritation sign. There were increases in peripheral white blood cells and neutrophils, but reductions in the hemoglobin level and platelet count in the two children. They had a significant increase in C-reactive protein. There were hundreds or thousands of white blood cells in the cerebrospinal fluid, mainly neutrophils. Increased protein contents but normal levels of glucose and chloride in the cerebrospinal fluid were found. Head CT scan showed multiple hematomas in the right cerebellum and both hemispheres in one child. Bone marrow cytology indicated infection in the bone marrow, and both blood culture and bone marrow culture showed methicillin-resistant Staphylococcus aureus (MRSA). Both patients had cardiac murmurs and progressive reductions in the hemoglobin level and platelet count during treatment, and echocardiography showed the formation of vegetation in the aortic valve. Therefore, the patients were diagnosed with infectious endocarditis (IE). Vancomycin was used as the anti-infective therapy based on the results of drug sensitivity test. One child was cured after 6 weeks, and the other child was withdrawn from the treatment and then died. Dynamic monitoring of cardiac murmurs should be performed for children with unexplained fever, and echocardiography should be performed in time to exclude IE. IE should also be considered for children with purulent meningitis and skin and mucosal bleeding which cannot be explained by the reduction in platelet count.

Childhood polyarteritis nodosa (PAN) is a rare systemic vasculitis and the delayed diagnosis and treatment will cause high incidence of sequelae and high mortality. This article reports a girl with childhood PAN due to posterior reversible encephalopathy syndrome (PRES). The girl aged ten years was admitted to the hospital due to hypertension and convulsions for one month. She had complaints of headache, vomiting, and blurred vision before convulsions. At six months before admission, a mass was observed in the neck. The physical examination showed that she had hypertension and no abnormal findings in the central nervous system. The brain magnetic resonance imaging manifested long T1 and T2 signals, high signal intensities on fluid-attenuated inversion recovery (FLAIR) images, and iso-signal intensity on diffusion-weighted imaging in the white matter of the left occipital lobe. Therefore, the cause of convulsions was considered as PRES. Mass biopsy suggested PAN and no findings supported tuberculosis. The right kidney atrophy was observed by ultrasound examination. Emission computed tomography of the kidney showed multiple vascular stenosis and no blood perfusion in the right kidney, so PAN was confirmed. These findings suggest that PAN should be considered in patients with vasculitis who had involvements of multiple systems after excluding common vasculitis, such as Kawasaki disease and Henoch-Schönlein purpura. Biopsy and angiography should be performed as early as possible for timely diagnosis and treatment.

Objective To observe the effect of transfection with lentivirus carrying Ifi204 genes on the expression of p204 in rat vascular adventitial fibroblasts. Methods Culturing the vascular adventitial fibroblasts of rat aortic and then conducting immunocytochemistry to identify the type and purity of these rat fibroblasts. The vascular adventitial fibroblasts of rat aortic cultured were transfected with lentivirus vector system carrying Ifi204 genes (Ifi204 group), the fibroblasts which has been transfected with the empty vector lentivirus particles as the control group (group C), and the untreated fibroblasts as the blank group (group N). The expressions of mRNA and protein of p204 in the fibroblasts were detected by realtime fluorescent quantitative PCR and Western blot test separately. Results There was expression of p204 in group N. Compared with group N and group C, mRNA and protein expression of p204 in the Ifi204 group had been all upregulated (P＜0.01). Conclusions There is structural expression of p204 in vascular adventitial fibroblasts of rat aortic. Transfection with lentivirus carrying Ifi204 genes can upregulate the expression of p204 in vascular adventitial fibroblasts.

Objective To detect the resistance index and esterase activity of each generation of DDVP-resistant Culex mosquitoes and analyze the relationship between insecticide resistance and esterase. Methods WHO bioassay and micro-plate measurement were used for the detection. Results The resistance index increased to 12.17 after 43 generations' insecticide selection compared to 1.00 as sensitive isolate. The nonspecific esterase(NSE) activity of the mosquitoes became strengthened with the extension of the generations, and the individual frequency of those with OD values no less than 0.9 increased gradually, consistent basically to the bioassay. The AChE average inhibition rate decreased with the extended generation and increased resistance, and the individual frequency of those with inhibition rate less than 30% became strengthened with the extension of generations, showing a positive correlation. Conclusion The activity of NSE and AChE shows a correlation with DDVP resistance.

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.

OBJECTIVE: To discuss the causes for changes of opinions in reappraisals of mental disabilities due to traffic accidents. METHODS: Fifty-one reappraisals of mental disorders due to traffic accidents from October 2009 to October 2011 in the Institute of Forensic Science, Shaoxing Seventh People's Hospital, were retrospectively analyzed. RESULTS: In the reappraisals, the opinions about disability grade changed in 30 cases (58.82%), including 8 cases increased and 22 cases decreased. According to the causes of changing the opinions, there were 8, 10 and 2 cases related to different understandings of appraisers in the severities of mental disorders, subjective judgements and certain psychiatric symptoms, respectively. Also, there were 10 cases related to different appraisal time. CONCLUSION Appraisals of mental disabilities should grasp the appraisal time, decrease the changes of opinions due to the differences of appraisers and correctly understand the orders of rules and clauses.
